One-handed wearable glove

Abstract

A single-hand wear and doff (SHWT) glove can protect the hands and fingers from direct contact with undesirable objects, such as hot, dirty, or corrosive objects, while maintaining the dexterity of the fingers to effectively complete tasks. The SHWT glove provides different finger combinations (optionally including the thumb as one of the fingers), for use by people with different finger and hand sizes, can be worn and doffed with a single hand (for single-handed operation), and has improved mechanical properties and leverage. Human hand sizes vary from small to large, and the SHWT glove is suitable for small, medium, and large hands. The SHWT glove can be constructed from different materials, and the material thickness can be varied in different parts of the finger gloves. The materials selected and the thickness applied can vary the elasticity, stiffness, bendability, or stretchability of the SHWT glove.

Description

[0001] Cross-reference to related applications

[0002] This application claims priority to U.S. Provisional Patent Application No. 63 / 616,509, filed December 29, 2023, entitled “Wearable Glove for One Hand,” and U.S. Provisional Patent Application No. 63 / 666,108, filed June 29, 2024, entitled “Wearable Glove for One Hand,” both of which are incorporated herein by reference in their entirety. Technical Field

[0003] This disclosure relates to various aspects of personal protective equipment, and more specifically to protective devices for the protection of fingers and hands in kitchens, laboratories, hospitals, shops, factories, offices, garages, workshops or other environments. Background Technology

[0004] Grasping objects is an essential aspect of daily life, as people use their hands to grasp things throughout the day. Heat-resistant gloves, heat-resistant mats, and plate mats are most commonly used for holding heated kitchen utensils. Because heat-resistant gloves are often large and bulky, users may find it difficult to grip objects securely and may need the assistance of a second hand to put them on. Heat-resistant mats do not cover the area to be grasped well and are prone to slipping. Therefore, unless extra care is taken when using heat-resistant gloves and heat-resistant mats, the user's hands can easily come into contact with heated utensils. Consequently, neither heat-resistant gloves nor heat-resistant mats provide a safe and convenient mechanism for using cooking utensils.

[0005] Gloves are sometimes used to protect hands from heated surfaces or other unwanted objects (such as raw meat, corrosive or hazardous substances) and to enhance grip strength. Gloves used for such purposes may cause discomfort due to wrinkling and buildup in their construction materials. Furthermore, gloves should be sized to fit the user's hand properly to provide both enhanced grip and protection.

[0006] Existing finger gloves are either too restrictive in their use, provide insufficient protection for the hands or fingers, fail to enhance grip strength or adequately empower users to grasp objects, or have other problems. None of the existing solutions provide an effective means of gripping and protecting the user's hands during cooking or other activities.

[0007] Therefore, a glove that can be put on and taken off with one hand is needed. Summary of the Invention

[0175] This article discloses a single-handed put-on and take-off glove that protects the hand and fingers from direct contact with unwanted objects such as heated, dirty, or corrosive substances, while maintaining finger dexterity to efficiently perform the task at hand. This single-handed put-on and take-off glove is referred to below as SHWT and SHWT gloves.

[0176] One problem with traditional finger gloves is that they are configured with specific combinations of finger sleeve sizes, which, if not followed, make them difficult or impossible to use. For example, each finger sleeve of a traditional finger glove may only allow a single finger to be inserted. When a user wants to remove the traditional glove, they may need, for example, a second hand. For traditional gloves with larger finger sleeves, inserting a single finger into the sleeve may not be a practical option, or even if possible, the use of such a traditional glove will be affected. One reason for these problems with traditional finger gloves is the failure to understand and apply the various finger sizes, and the failure to fully understand finger movements (absolutely and interdependently), finger positions, various grasping geometries, and the associated movement, position, configuration, and shape of the finger glove to meet the conflicting needs of being easy to put on (by inserting fingers into the finger glove), easy to remove (simply by swinging, alternating movements between fingers within the finger glove), and simultaneously providing useful gripping and protection for the fingers and hand. Traditional gloves fail to meet these needs, so there is a need for a single-handed put-on and take-off glove to protect the hand during a variety of tasks. The gloves offer the flexibility and freedom to use different finger insertion combinations, as well as the ability to be easily put on and taken off with one hand.

[0177] The following are the limitations and drawbacks of traditional finger gloves: 1) Traditional finger gloves are designed to accommodate a specific number of fingers. For example, a finger glove with two finger sleeves can only accommodate two fingers, and a finger glove with three finger sleeves can only accommodate three fingers (one finger in each sleeve), etc. Therefore, they do not provide a universal protection solution for various tasks requiring two, three, four, or five fingers. This leads to the need for multiple finger gloves, each with a different configuration, each suitable only for one finger insertion pattern.

[0178] 2) Many finger gloves have round or near-round oval finger cots that tightly wrap around the inserted fingers to prevent slippage. This makes them difficult to put on and take off without the aid of a second hand. If the round finger cots are made too large, the gloves are prone to slipping off accidentally during use.

[0179] 3) Each finger sleeve of a finger glove is difficult to accommodate fingers of different sizes. If each finger sleeve is made too small, people with large fingers cannot wear it. If each finger sleeve is made too large, it may accidentally slip off the hand of someone with small fingers.

[0180] 4) Some finger gloves have narrow bridges connecting the finger sleeves. Finger gloves with this structure are unstable and cannot stand on their own, making them difficult to put on and take off without the aid of a second hand. They are also difficult to stack with one hand. They offer little protection for the palm.

[0181] 5) Some finger gloves have short finger sleeves that only cover the fingertips, leaving most of the fingers exposed and unprotected. If the finger sleeves are made too long, the gloves will be difficult to remove, especially without the aid of a second hand.

[0182] 6) Some finger gloves (especially short-finger gloves) have narrow bridges connecting the fingers far from the base of each finger. This requires the fingers to exert more force when two adjacent fingers inside the finger glove need to spread, making it more difficult to stretch wide to grasp large objects.

[0183] On one hand, each finger glove of the SHWT glove can accommodate one, two, or three fingers inserted at once, and can accommodate different sized fingers without relying on the elasticity of the glove material. SHWT gloves can be quickly put on and taken off without the need for a second hand or some other device to hold the fingers in place.

[0184] Using an ergonomic design approach, SHWT gloves solve many practical problems faced by other gloves on the market, problems that make these gloves conceptually appealing but impractical for actual use. SHWT gloves can keep fingers securely inside the glove without slipping during work, while still allowing the gloves to be put on and taken off without the aid of a second hand.

[0185] SHWT gloves allow hands to firmly grip both very small and large objects. SHWT gloves allow hands to open and close freely without feeling restricted. SHWT gloves provide a comfortable feel, closely resembling the sensation of bare hands, while offering protection for fingers, parts, or even the entire palm area. SHWT gloves can be worn on either the left or right hand. SHWT gloves can stand upright on flat surfaces without collapsing, aiding in one-handed wear and easy stacking for storage. SHWT gloves can also be used as cutlery holders.

[0186] SHWT gloves overcome the limitations of traditional finger gloves, offering different finger combinations, with the thumb selectable as one of the fingers. They are suitable for people with different finger and hand sizes, allowing for single-handed donning and doffing (for one-handed operation), and feature improved mechanics and leverage compared to previous versions. The term "finger" in this description can include both fingers and the thumb. For example, "5 fingers" can include 4 fingers and the thumb, or "4 fingers" can include 3 fingers and the thumb, or it can refer to 4 fingers excluding the thumb, and so on.

[0187] Human hands come in various sizes, from small to large. This section illustrates the structural dimensions, size, and shape of the SHWT glove, designed to fit a standard medium-sized hand, referencing the dimensions (size and shape) of such a hand. Using the design principles described, SHWT gloves can be scaled proportionally to small, medium, and large sizes to fit different hand sizes.

[0188] SHWT gloves can use different materials and vary the material thickness in different parts of the finger glove. The selected material and its applied thickness can alter the elasticity, stiffness, flexural capacity, or stretching capacity of the SHWT glove.

[0189] SHWT glove materials can be categorized into different types. Type I materials are low-elasticity or non-elastic but flexible materials with limited (or low) stretchability or no stretchability. Type I materials can be hard rubber, hard silicone with low stretchability (roughly estimated to be materials with a Shore A hardness greater than 80), or non-stretchable materials such as paper or flexible bendable plastics or other similar bendable but non-stretchable materials. One way to make Type I material-based SHWT gloves stretchable is to utilize the material's bendability to implement structurally foldable / compressible and expandable structures, such as in... Figure 16 and Figure 19 SHWT gloves incorporate horizontal, vertical, or serrated U / V-shaped grooves. Type I materials (e.g., paper-based materials) can be coated or laminated with different materials to achieve better water and oil resistance, or to modify / improve mechanical properties. Type I materials (e.g., paper-based SHWT gloves) can be partially or fully folded to reduce storage size. These folded SHWT gloves can be unfolded / deployed into a wearable shape to stand upright on a flat surface.

[0190] Type II materials are soft, stretchable, and bendable materials. Type II materials can be soft, elastic rubber, silicone, naturally occurring isoprene polymers, neoprene (a synthetic polymer of 2-chloro-1,3-butadiene), or any stretchable organic material. Typical Shore A hardness for Type II materials can be below 80. Typical Shore A hardness for Type II materials can range from approximately 20 to 60 (this is an estimate for illustrative and representative hardness ranges only). Using SHWT gloves made of Type II materials with varying thicknesses at the same Shore hardness can also alter the bendability and stretchability of the SHWT gloves. Thinner materials with the same Shore hardness can have better stretchability. Type II materials can be coated or laminated with other materials to achieve certain physical and mechanical properties to improve the usability and performance of the SHWT gloves. SHWT gloves using Type II materials can utilize the material's inherent stretchability or combine it with a structure-based stretchable structure (e.g., Figure 16 and Figure 19 (Example of U / V shaped grooves) to achieve elasticity and stretchability.

[0191] SHWT gloves can use Type I or Type II materials, and the material thickness can be varied in different parts of the glove body to achieve different elasticity, bendability and flexibility properties.

[0192] In the following description, we will refer to and use specific finger anatomy terminology. Figure 2 A shows the anatomical terminology and corresponding labels for all finger joints. The metacarpophalangeal joint (MCP) refers to the palmar joint of all fingers; the distal interphalangeal joint (DIP) refers to the distal phalangeal joint of all fingers; and the proximal interphalangeal joint (PIP) refers to the intermediate joint of the four fingers excluding the thumb. The thumb does not have a PIP joint but has a unique CMC joint located near the wrist, such as... Figure 8 As shown in C. To specifically distinguish the joints of each finger by marking them, we use the first letter of each finger's name as a prefix to the general markings for the finger joints. For example, we can call the DIP joint of the thumb T-DIP and the PIP joint of the index finger I-PIP. The same convention applies to all finger joints.

[0193] In the following description, we refer to hands in a relaxed, open position, for example... Figure 2 A, Figure 2 B Figure 8 B and Figure 8 The posture of the right hand 202b shown in C. More specifically, when the hand is in Figure 2 A, Figure 2 B Figure 8 B and Figure 8 When C is in a relaxed, open posture, the MCP joint of the thumb (T-MCP joint 271) and the MCP joints of the other fingers (272, 273, 274 and 275) are used as the apex of the angle, and the palm and the finger segments connected by each MCP joint form a large obtuse angle of nearly 180 degrees.

[0194] When we refer to a clenched hand, it means the hand is closed to grasp or hold an object and all the fingers are touching near their tips. Figure 12 B Figure 12 C Figure 12 D and Figure 12 The right hand 202b shown in E is grasping a small object. For illustration, refer to... Figure 15 A, Figure 15 B Figure 15 C and Figure 15 The hand in picture D is wearing SHWT gloves and is in a clenched position.

[0195] In the following description, we define parallel insertion of a finger into a finger sleeve as: the two lateral vertices of the inserted finger are approximately on the same line as the two lateral vertices of the finger sleeve. Figure 2 D shows the thumb's cross-section 211C inserted parallel to the top finger sleeve, the index finger's cross-section 212C and the middle finger's cross-section 213C inserted parallel to the lower left finger sleeve, and the ring finger's cross-section 214C and the little finger's cross-section 215C inserted non-parallel to the lower right finger sleeve.

[0196] Note that in the following description, any markings with a number followed by a capital "C" indicate a cross-sectional view, such as 108C or 106C.

[0197] Figure 1 A, Figure 1 B Figure 1 C shows the SHWT glove 100 with three finger sleeves 101. Figure 1 B shows that each finger sleeve has an open end 102 at the top and a closed end at the bottom. Figure 1 C), the open end at the top joins at the central connection area 103. Figure 1 B illustrates that the central connecting region 103 is implemented as a triangular region. Alternatively, the central connecting region can be other shapes or be hollowed out. The central connecting region can also be raised in the middle to form a raised shape for the hand to grasp or pick up the SHWT glove, such as... Figure 21 As shown in B. Figure 21 The carrying loop 317 shown in Figure A can be added to the central connection area to hang SHWT gloves on the hook.

[0198] SHWT gloves are structurally designed to stand upright on a flat surface. Figure 2 A illustrates one aspect of an SHWT glove 100, which stands upright on a flat surface such that the end of each finger cot contacts the flat surface with the open end 102 facing upwards, ready for finger insertion. Such a flat surface could be a kitchen countertop in a home. The ends of all the finger cots in the SHWT glove form a sitting plane. In one aspect, the "sitting plane" is a virtual plane formed by the ends of the finger cots of the SHWT glove. In another aspect, the "sitting plane" is a virtual plane formed by the finger cots of the SHWT glove at 0% of the finger cot height (SH) (see below). The sitting plane can be analogous to a plane formed by a table, for example, when the ends of the finger cots contact the table, such as if the SHWT glove is on a table and the ends of the finger cots are touching the table and positioned to allow fingers to be inserted from above. The sitting plane is defined to better explain the various geometries of the SHWT glove.

[0199] In this description, the cross-section of the SHWT glove and the cross-section of the finger sleeve are defined as two-dimensional cross-sections parallel to the sitting plane or the flat surface on which the SHWT glove may stand.

[0200] Figure 1The longitudinal sectional perspective view of D shows that the finger sleeves of the SHWT glove have an inner wall 109C and an outer wall 104C, with the inner wall 109C closer to the central connecting region 103 than the outer wall 104C along the cross-section of each finger sleeve. On one hand, the side sections of the finger sleeve (e.g.) Figure 10 A and Figure 10 The left and right segments centered at the side vertex 100S in section B, whether lateral arcs or other structures, can be used as references for separating the inner and outer walls. In one sense, the inner wall of the finger sleeve can be considered the finger sleeve wall facing or in contact with the object being grasped, or the finger sleeve walls facing or in contact with each other when the hands of a user wearing the SHWT glove are in a clenched position. Each finger sleeve has an inner surface (the surface inside the finger sleeve) and an outer surface (the surface outside the finger sleeve).

[0201] Figure 1 A, Figure 1 C Figure 8 A, Figure 9 A, Figure 9 E, Figure 13 D、 Figure 15 E illustrates the SHWT glove having a glove bottom center (GBC) on the sitting plane. (See diagram) Figure 1 C and Figure 13 As shown in Figure D, in a three-finger sleeve-based SHWT, the glove bottom center (GBC) is the center of the contact circle 002, which creates at least one contact point 003 with the inner wall of the end of each finger sleeve. When the finger sleeve contacting the contact circle is an arc or an angle, such as... Figure 13 As shown in D, the contact circle and the finger sleeve form exactly one contact point. In some cases, the finger sleeve can form multiple contact points with the contact circle, for example, when the finger sleeve has multiple arcs and the peak of each arc contacts the contact circle. The contact circle is outside the finger sleeve, such that, in one aspect, multiple contact points may exist between the contact circle and the outer surface of the finger sleeve, while the contact circle does not intrude into the inner surface of the finger sleeve. In another aspect, the contact circle having only a single contact point with the finger sleeve will also remain outside the finger sleeve, without intruding into the inner surface of the finger sleeve. In one aspect, the end of the finger sleeve can be configured to contact the contact circle.

[0202] In a four-finger SHWT glove, the inner walls of the ends of any three of the four finger cots can create a contact circle, resulting in a total of four contact circles in a four-finger SHWT glove, each belonging to a different group of three finger cots. On one hand, the bottom center (GBC) of a four-finger SHWT glove with multiple contact circles is the center of the smallest contact circle. On another hand, a four-finger SHWT glove can have four perfectly overlapping contact circles. In this case, the center of the four (overlapping) contact circles is the bottom center (GBC) of the four-finger SHWT glove. On another hand, if two or more contact circles perfectly overlap and the remaining contact circles are larger, the center of these two perfectly overlapping contact circles is the bottom center (GBC). On yet another hand, in overlapping contact circles, when there is no smallest contact circle because all contact circles are the same size, the bottom center (GBC) is the center of any overlapping contact circle.

[0203] On one hand, the ends of the four finger sleeves can be configured to contact multiple contact circles. For example, the finger sleeves may be labeled as first finger sleeve, second finger sleeve, third finger sleeve, and fourth finger sleeve, and they can contact the following contact circles: First, second, and third finger sleeves can be configured to contact the first contact circle. Second, third, and fourth finger sleeves can be configured to contact the second contact circle. First, third, and fourth finger sleeves can be configured to contact the third contact circle. First, second, and fourth finger sleeves can be configured to contact the fourth contact circle.

[0204] SHWT gloves have a vertical axis orthogonal to the sitting plane, which in one respect can be a flat standing surface. Figure 1 A, Figure 8 A, Figure 9 A and Figure 15 E illustrates a vertical line along the vertical axis of the SHWT glove, from the central connection area to the seating plane passing through the center of the glove bottom (GBC). This vertical line will be referred to as the center SH line. The intersection of the cross-sectional plane of each SHWT glove with the center SH line will be referred to as the glove center (GC) of that cross-section. Figure 13 C shows the center of the glove (GC) in a cross-section of the SHWT glove based on a three-finger cot. Figure 13 The bottom center (GBC) of the glove in D is located at the center (GC) of the glove on the sitting plane.

[0205] The SHWT glove is rotationally symmetrical about the central SH line. Figure 1 B and Figure 1 C, shown in perspective, illustrates that the SHWT glove 100 is rotationally symmetrical and has three identical finger sleeves 101 (101 is shown in...). Figure 1 A and Figure 1 (C in the middle). Figure 13 A and Figure 13 B shows that the SHWT glove 250 is rotationally symmetric and has four identical finger sleeves. Note that in the rotationally symmetric four-finger sleeve-based SHWT glove, the four contact circles created by any three finger sleeves on the inner wall at the ends completely overlap, as if they were a single contact circle. The center of the overlapping contact circles is the bottom center (GBC) of the rotationally symmetric four-finger sleeve-based SHWT glove.

[0206] Rotationally symmetrical SHWT gloves may offer advantages over conventional gloves. These advantages include, but are not limited to: universal adaptability to any inserted finger or finger combination, and the ability of SHWT gloves to be stacked with identical SHWT gloves, where any finger sleeve can be nested within the finger sleeve of the stacked SHWT glove. On the other hand, SHWT gloves do not have to be rotationally symmetrical. One example of a non-rotationally symmetrical SHWT glove is that the finger sleeves have different shapes from each other. Other examples of non-rotationally symmetrical SHWT gloves include: the printed pattern on each finger sleeve can be different, or a hanging hole for convenient hanging can be added at the top edge of the SHWT glove, below the top edge rim 107 (see [link to relevant documentation]). Figure 1 A and Figure 1 B).

[0207] The finger sleeves of the SHWT glove have a finger sleeve height (SH) along the vertical axis of the SHWT glove. Figure 21 A shows a rotationally symmetrical SHWT glove 125 divided equally (by a 120-degree longitudinal cut along the UC line from the center) into three separate finger sleeves. The UC line will be discussed later. Figure 21 C is from Figure 21 A longitudinal sectional isometric side view of a single finger glove cut in half, showing the finger glove height (SH), which is the distance along the vertical axis from the outer surface of the finger glove's end on the sitting plane to the bottom surface of the central connecting area. The finger glove height (SH) is not a direct measurement of the distance from the central connecting area to the finger glove's end. When the central connecting area is generally flat or has a convex spherical (dome) structure, the measurement point for the finger glove height (SH) at the central connecting area is located at the intersection of the central SH line (a vertical line from the center of the glove's bottom (GBC)) and the bottom surface of the central connecting area. For information on how to determine the measurement point for the finger glove height (SH) at the central connecting area when the central connecting area has a concave spherical (inverted dome) structure or a U / V-shaped groove, please see below. Figure 21 C and Figure 21As shown in D, the finger sleeve can be measured vertically as a percentage of the finger sleeve height (SH), from the outer surface of the bottom finger sleeve end to the bottom surface of the central connecting area. 0% of the finger sleeve height (SH) is located at the outer surface of the finger sleeve end or the sitting plane, and 100% of the finger sleeve height (SH) is located at the bottom surface of the central connecting area. When the central connecting area contains a convex spherical (dome) structure and its highest point is located on the central SH line, the central connecting area can be considered as a point.

[0208] Figure 13 C shows the clamping radius (RC) of the finger sleeves in the SHWT glove on the cross-sectional plane of the SHWT glove. The clamping radius (RC) of each finger sleeve begins at the center of the glove (GC) and bisects the clamping angle β. The apex of the clamping angle β is located at the center of the glove (GC), and each side of the clamping angle β clamps one side of the finger sleeve with at least one contact point.

[0209] Figure 13 D illustrates the bottom clamping radius (BRC) of the SHWT based on three-finger cots on a cross-sectional plane at 0% of the finger cot height (SH). The bottom clamping radius (BRC) of each finger cot begins at the center of the glove bottom (GBC) and bisects the clamping angle β. The angular vertex of the clamping angle β is located at the center of the glove bottom (GBC), and each side of the clamping angle β clamps one side of the finger cot with at least one contact point. Figure 13 D shows that one side of the finger sleeve contacts clamping angle β with an arc, and the other side contacts clamping angle β with an angle. When the sides of the finger sleeve are straight lines overlapping the side of angle β, they will create more than one contact point. The bottom clamping radius (BRC) is the clamping radius (RC) at 0% of the finger sleeve height.

[0210] The cross-section of the finger sleeve has a width (OW) and a height (OH), such as Figure 10 B Figure 10 C Figure 11 C Figure 13 C Figure 13 D、 Figure 21 E and Figure 23 As shown in C. Figure 21 E and Figure 23 As shown in Figure C, the cross-section of the finger sleeve is placed in an XY coordinate system, where the y-axis is parallel to the gripping radius (RC) of the finger sleeve, and the height (OH) is parallel to the gripping radius (RC), representing the distance between the highest and lowest points on the finger sleeve along the Y-axis. The width (OW) is orthogonal to the height (OH) and represents the distance between the leftmost and rightmost points on the finger sleeve along the X-axis. Note: Each finger sleeve cross-section has its own XY coordinate system, where the Y-axis is always parallel to the gripping radius (RC) of that finger sleeve. When measuring the width (OW) and height (OH) of the finger sleeve cross-section, the outer surface of the finger sleeve is used, excluding any additional structures on the outer surface, such as... Figure 2 Printed pattern 206 in A.

[0211] refer to Figure 13 D. The height (OH) of the finger sleeve has two OH-end horizontal lines 008, which are perpendicular to the bottom clamping radius (BRC) of the finger sleeve and are determined as follows: One OH-end horizontal line 008 contacts the inner wall of the finger sleeve with at least one contact point, and the other OH-end horizontal line 008 contacts the outer wall of the finger sleeve with at least one contact point. When a section of the finger sleeve wall overlaps with an OH-end horizontal line, it will create more than one contact point with that OH-end horizontal line. The length of the bottom clamping radius (BRC) at 0% of the finger sleeve height is measured from the center of the glove bottom (GBC) to the OH-end horizontal line 008 that contacts the inner wall of the finger sleeve. The bottom clamping radius (BRC) is measured from the center of the glove bottom (GBC), as follows: Figure 9 As shown in Figure A.

[0212] like Figure 13 As shown in Figure C, the clamping radius (RC) above 0% of the finger sleeve height (SH) is measured from the glove center (GC) of the corresponding cross-section. For example, the clamping radius (RC) of an SHWT glove at a cross-sectional plane at 50% of the finger sleeve height (SH) is measured from the glove center (GC) at 50% of the finger sleeve height. The clamping radius (RC) of the finger sleeves may differ at different percentages of finger sleeve height. In an SHWT glove, the SHWT glove is non-rotationally symmetric when the clamping radii (RC) of the finger sleeves on the same cross-sectional plane are different from each other. The clamping radius (RC) and bottom clamping radius (BRC) in a four-finger SHWT glove are defined using the same method.

[0213] When the central connecting area has a concave spherical (inverted dome) structure or a U / V-shaped groove, we can use the bottom clamping radius (BRC) as a reference to determine the measurement point of the finger sleeve height along the central SH line at the central connecting area.

[0214] Figure 21 B illustrates the case of adding a U / V-shaped groove in the central connection area. The finger sleeve height (SH) at the central connection area should terminate at the 1 / 2 PV-H level, that is, half the distance between the bottom surface of the central peak "P" and its adjacent valley "V" on the U / V-shaped groove within a circular area 005 with a radius of 25% of the bottom clamping radius (BRC) on the central SH line. The conclusion is that when the central connection area within a circular area centered on the central SH line and with a radius of 25% of the bottom clamping radius (BRC) is neither flat nor a convex spherical (dome) structure, but rather a concave spherical (anti-dome) structure or a U / V-shaped groove, the finger sleeve height (SH) at the central connection area can be measured to terminate at half the height between the bottom surfaces of the highest and lowest points within that circular area (e.g., ...). Figure 21 (1 / 2 PV-H in B).

[0215] When measuring the finger sleeve height (SH), additional structures added above or below the central connecting area 103 (e.g., Figure 21 The lifting loop 317 in A is not included in the finger sleeve height (SH).

[0216] Figure 10 A, Figure 10 B Figure 10 C Figure 10 D、 Figure 10 E illustrates SHWT gloves 100, 230, 150, 130, and 170, all of which have finger sleeve cross-sections that are symmetrical along the clamping radius (RC). On the other hand, the cross-sections of the SHWT glove finger sleeves may not be linearly symmetrical. Figure 13 D shows that the cross-section of the finger sleeves is not linearly symmetrical, but rather the three finger sleeves are rotationally symmetrical about the central SH line. A rotationally symmetrical SHWT glove with each finger sleeve being linearly symmetrical would have advantages, including but not limited to: universal adaptability to the left or right hand, universal adaptability to inserting any finger or finger combination into a single finger sleeve, and a stackable SHWT glove body.

[0217] refer to Figure 13 C. The cross-sectional plane of the SHWT glove has UC lines, each UC line originating from the glove center (GC) and bisecting the angle between two adjacent clamping radii (RC). In a rotationally symmetric SHWT glove with three finger sleeves (e.g....), Figure 13 In the SHWT glove 100 shown in C, there are three clamping radii (RC) on each cross section, which are 120 degrees apart from each other. The UC line is 60 degrees away from its adjacent clamping radius (RC), which is half the angle between two adjacent clamping radii (RC). Figure 13 D shows a rotationally symmetric SHWT glove with three UC lines at 0% finger height and its relative position to the bottom clamping radius (BRC).

[0218] The longitudinal axis of each finger sleeve, extending from the top to the bottom, may not be perpendicular to the sitting plane or a flat standing surface. One design allows the longitudinal axis of the finger sleeve to be tilted at a non-orthogonal angle, but orthogonal or near-orthogonal longitudinal axes of the finger sleeves can help SHWT gloves achieve various purposes, such as easy direct insertion of fingers for self-wearing, and making SHWT gloves stackable.

[0219] On one hand, the SHWT glove can be configured to accommodate a single finger in each finger sleeve, with sufficient friction between the finger sleeve and the user's finger to allow the user to insert their finger into the SHWT glove, and for the SHWT glove to be held on the user's finger due to the friction of the finger sleeve. On the other hand, the SHWT glove configured to accommodate a single finger in each finger sleeve can also be configured to accommodate multiple fingers in a single finger sleeve, accompanied by friction to hold the SHWT glove on the user's finger, while still allowing the user to easily remove the SHWT glove without the assistance of a second hand.

[0220] Figure 2 A, Figure 2 B Figure 2 C and Figure 2 D shows three-dimensional and two-dimensional views of one way to wear the SHWT glove 100: the index and middle fingers are inserted parallel to each other into the first finger cot, the ring and little fingers are inserted non-parallel into the second finger cot, and the thumb is inserted parallel to each other into the last finger cot. Another way to wear the SHWT glove 100 is to insert the thumb and index finger into one finger cot each, and the middle, ring, and little fingers into the remaining finger cots together. Note that the little finger may not be fully inserted into the finger cot body because it is shorter than the ring and middle fingers. The little finger can also be retracted outside the finger cot while working and can push against the edge of the glove body after work to help remove the glove without a second hand.

[0221] Figure 13 A and Figure 13 B illustrates an alternative design in which the SHWT glove 250 may include four identical finger sleeves. Using four finger sleeves, three fingers can each be inserted into one sleeve, and the remaining two fingers can be inserted into the last sleeve. For example, the thumb, index finger, and middle finger can each occupy one sleeve, while the ring finger and little finger can share the last sleeve.

[0222] SHWT Glove 100 has three arched sections 108 (such as...) Figure 1 As shown in B), the central connecting area 103 (as shown in B) Figure 1 (as shown in B) and the top skirt (e.g.) Figure 5 A palm protection section formed by SW03 (with three inter-arc bridging fins 216c1). When the top skirt includes inter-arc bridging fins 216c1, the horizontal portion of 216c1 is also part of the arch bridge section 108. The three arch bridge sections 108, the horizontal portions of the connecting inter-arc bridging fins 216c1, and the central connecting area 103 protect the central palm area and the inner root area of ​​the fingers, while Figure 5 The top skirt of A and the SW03 inter-arc bridging flap extend upwards to further protect the edge of the palm and the base of the fingers. Figure 5 The SW03 illustration of D shows the fully inserted hand protected by the top skirt in these extra areas of the SHWT glove.

[0223] Figure 1 B and Figure 1 D shows the arched bridge sections 108 (and 108C) connecting two adjacent finger sleeves and extending as a single unit from the top of the finger sleeves. This integrated design, along with the top skirt SW03, provides enhanced protection for the palm.

[0224] High top skirt SW07 ( Figure 17 A) and SW08 ( Figure 19 A) Further extend the palm protection upwards to wrist level.

[0225] To better describe the top hem, we divide the SHWT Glove 100 into the lower and upper sections, as follows: Figure 5 and Figure 6 As shown. In one respect and as Figure 5 and Figure 6 As shown, the top skirt surrounds the finger cots, such as finger cot 101 in a three-finger SHWT glove, or finger cots in a four-finger SHWT glove (not shown). Figure 5 and Figure 6 (As shown in the image).

[0226] Figure 5 A, as shown in the SHWT glove 100, depicts a lower portion that is a finger protection body 100f, comprising three finger sleeves 101 and a partial arched section 108 joined at a central connecting area 103. (See image.) Figure 5 B and Figure 21 As shown in Figure C, the height 100f-H of the finger protector body 100f is equal to the height of the finger sleeve (SH) plus the wall thickness 505 of the central connecting area. The top is an upward-extending top skirt SW03.

[0227] It should be noted that SHWT gloves without an upwardly extending top skirt still offer some finger protection and application functionality, but they do not provide as much palm protection and SHWT body structure stiffness enhancement. Figure 5 B shows the SHWT glove 111 without an upwardly extending top hem. For better illustration, Figure 5The right side of B shows that the SHWT glove 111 can be divided into a lower finger protection body 100f and an upper SW00. SW00 is a non- (or zero) upward-extending top skirt, as it has no upward-extending skirt wall above the finger protection body 100f. In SW00, the top edge rim 107 and the top flat finger sleeve connection 330 of the horizontally extending arched section 108 provide partial palm protection above the finger protection body 100f. They also provide limited structural reinforcement to increase the rigidity of the SHWT glove 111.

[0228] One function of the upward-extending top skirt is to provide extra protection in the area around the edges of the palm and the base of the fingers, such as... Figure 5 D's SW03 and Figure 6 As shown in SW02 and SW05 of A.

[0229] One function of the upward-extending top skirt is to provide further structural reinforcement to the lower finger sleeve body and increase the rigidity of the SHWT glove body. This reinforcement helps the SHWT glove stand upright on a flat surface and prevents the glove from collapsing during single-handed finger insertion, such as... Figure 2 A and Figure 2 As shown in B. This reinforcement helps to easily reinsert a finger cot after it has been temporarily removed from one cot while the other cot still has a finger inserted (or when the SHWT glove is partially worn with two finger cots). For example, in Figure 2 D and Figure 2 In the SHWT glove 100 shown in C, if the ring finger 214 and little finger 215 are removed from their finger sleeves, while the remaining fingers are still inserted into the other two finger sleeves, the empty finger sleeves may still remain firmly in their relatively original positions without the top finger sleeve opening falling down due to the increased stiffness of the palm protection section provided by the top skirt. This allows the removed fingers to be easily reinserted into the finger sleeves. This also helps prevent still inserted fingers from slipping out of the finger sleeves, especially for finger sleeves with only one finger inserted.

[0230] The top skirt that extends upwards (e.g.) Figure 5 C and Figure 6 One embodiment of SW01 shown in A can be described as extending upward from the top of the outer wall of the finger sleeve above the finger protection body 100f. Figure 6 A and Figure 6 B shows the SHWT glove 121 with SW01 as its top skirt.

[0231] However, due to the anatomical structure of the human hand, when fingers attempt to fully insert into SHWT gloves 121 with a specific finger sleeve height (SH will be discussed in more detail below), Figure 6 In case B), such as Figure 5 C and Figure 5 As shown in D, the sudden bulge of the thenar eminence 219 near the base of the thumb, close to the MCP crease 287, will... Figure 5 At position 506 in D, push outwards and thus deform / bend the upward top edge wall of SW01. When the hand is fully inserted into SHWT glove 121 ( Figure 6 B) When performing a gripping motion, the sudden outward tilt of the thenar eminence 219 at the base of the thumb further presses the corresponding SW01 top edge against the... Figure 5 Press down at position 506 in D. This may cause the thumb to move and slide inside the finger sleeve.

[0232] When wearing SHWT gloves 121 with a selected finger cot height (SH) Figure 6 B) When the hand is repeatedly opened and closed, the protrusion from the thenar eminence 219 (see Figure 3 B and Figure 7 A) This may cumulatively press down on the top edge of SW01, causing it to lower and the thumb to move upward a distance D from its fully inserted position, such as... Figure 5 As shown in D. The maximum movement distance D occurs when the upward top edge of SW01 finally reaches the level of the thumb MCP fold 287 and no longer contacts the suddenly protruding thenar eminence 219.

[0233] Since the thumb typically occupies a single finger sleeve in actual use, repeated gripping motions can cause the thumb tip to move upwards away from the end of the finger sleeve without ever touching it. This can affect the grip performance of SHWT gloves.

[0234] During the hand grasping action, the top edge wall of SW01 is pushed by the sudden protrusion from the thenar eminence 219, possibly because the shape of its top edge wall does not match the shape of the lateral protrusion of the thenar eminence 219, thus hindering the hand movement.

[0235] The improved top skirts SW02, SW03 and SW05 described below all have skirt wall shapes that match the shape of the thenar eminence 219 protrusion, thus avoiding the problem of thumb displacement and slippage.

[0236] To avoid the pushing effect of the thenar eminence 219 protruding during hand grasping movements, measures such as... Figure 6 A and Figure 7 The top skirt of SW02 shown in C is constructed by tilting the skirt wall in SW01 outward to follow the raised shape of the thenar eminence 219 across the entire lateral circumference of the skirt.

[0237] Figure 6 SHWT gloves 122 in B are implemented Figure 6A has a top skirt SW02 with an outwardly sloping wall, positioned at the base of the thumb. Figure 5 The area around position 506, indicated by D, provides space for the protrusion from the thenar eminence 219. This allows the thumb to be inserted more fully into the end of the finger sleeve by an additional distance of D, without bending or twisting the top edge of the skirt, and preventing the thumb tip from sliding upwards due to hand gripping movements.

[0238] However, an outward-sloping hem design may create a large opening at the top of the hem, resulting in less snug protection for the rest of the hem (excluding those around the base of the thumb and little finger) for other fingers that can be inserted into other finger sleeves.

[0239] Another type of top skirt, such as Figure 5 A and Figure 5 As shown in D, SW03 can be improved by adding an inter-arc bridging winglet 216c1 below the thenar eminence 219 protrusion in the design of SW01 (e.g., Figure 5 As shown in A) and notch Nh (as shown in A) Figure 5 To implement (as shown in D).

[0240] The top skirt SW03 is rotationally symmetrically embedded with three inter-arc bridging fins 216c1, as... Figure 1 A, Figure 1 D、 Figure 3 C and Figure 5 As shown in Figure A, each inter-arc bridging flap begins at a relatively flat point at the top of the partial arch section 108, then transitions at the transverse edge of the skirt to an upward-facing wall, becoming part of the skirt wall. It may be higher than the rest of the skirt wall.

[0241] for Figure 2 A, Figure 2 B. Figure 2 C and Figure 2 As shown in Figure D, an SHWT glove 100 wearing assembly is provided, in which the thumb is inserted into one finger cot, the index and middle fingers are inserted into one finger cot, and the ring and little fingers are inserted into a final finger cot. Figure 2 A, Figure 2 B. Figure 2 C and Figure 2 D shows three interarc bridging flaps 216c1 roughly located between the base of the middle and ring fingers, the base of the thumb and index finger, and the hypothenar eminence 217 and the thenar eminence 219 (see [reference]). Figure 3 B and Figure 3 C). The slope of the inter-arc bridging flap 216c1, transitioning from the horizontal arch section to the upward-facing skirt wall, can approximate the slopes of the aforementioned interdigital root region and the hypothenar and thenar eminence regions, with particular consideration given to the slopes of the deformed shapes in these regions under a clenched grip. The shape of the inter-arc bridging flap of the SHWT glove when the user's hand is in a clenched grip... Figure 3 A, Figure 3 B and Figure 4 Figure A shows the area located between the hypothenar eminence 217 and the thenar eminence 219, and between the base of the thumb and index finger. Figure 4 A and Figure 15 Figure B shows the area located between the base of the middle and ring fingers. The SW03 design allows the SHWT glove to better fit the left or right hand and better protect the aforementioned hand area, while reducing finger slippage and displacement issues.

[0242] A portion of the inter-arc bridging flap 216c1 (e.g., its upwardly extending portion) can reinforce the arch bridge section 108 to increase the stiffness of the palm protection section and generate additional stiffness between the connecting portions of two adjacent finger sleeve bodies. The increased stiffness of the palm protection section can further help prevent the SHWT glove 100 from collapsing on a flat surface during finger insertion (see...). Figure 2 A).

[0243] The increased stiffness of the inter-arc bridging flap 216c1 in SW03 allows temporarily removed fingers to be easily reinserted into empty finger sleeves while the remaining fingers are still in the other two finger sleeves, keeping the empty finger sleeve near its original position.

[0244] In addition, the inter-arc bridging wing 216c1 has a flip-up design. Figure 3 C shows that when the hand wearing the SHWT glove is in a relaxed, open position, the inter-arc bridging flap 216c1 stands upright at the lateral edge of the top skirt.

[0245] and Figure 3 Compared to C's relaxed and open posture. Figure 3 A and Figure 3 B illustrates the inter-arc bridging flap 216c2 in an outward-flipped state when the hand wearing an SHWT glove is in a clenched position. When the hand is closed to grasp an object, if the larger inter-arc bridging flap 216c1 is not flipped, the top edge of the inter-arc bridging flap 216c1 may move upward and push against the palm area near and between the thenar eminence 219 and the hypothenar eminence 217 (see [reference]). Figure 3 B).

[0246] Figure 3 B shows the inter-arc bridging wing 216c1 gradually flipping outward within the arrow circle. The structurally flippable inter-arc bridging wing (due to its horizontal portion being directly integrated with the arch section) allows for smoother gripping motions for the hand wearing SHWT gloves, and the outward-flipping inter-arc bridging wing extends the protection area of ​​the palm towards the wrist.

[0247] The top skirt SW03 also adds notches Nh on both sides of each inter-arc bridging wing 216c1 (such as... Figure 5 D and Figure 6 As shown in A). They can be symmetrical along the UC line of the SHWT glove cross-section (see Figure A). Figure 13 C understands UC line). Two additional notches Nh (e.g.) Figure 5 D and Figure 6 (As shown in A) Located below the thenar eminence 219 protrusion, it facilitates the full insertion of the left or right thumb into the end of the finger sleeve within the finger sleeve with a selected finger sleeve height (SH). This prevents the thenar eminence protrusion from contacting the top edge of the skirt and prevents thumb retraction during hand grasping movements. The notch in SW03 achieves the same effect as the outwardly sloping skirt wall design in SW02, but leaves the thenar eminence 219 protrusion outside the top skirt.

[0248] Figure 5 C and Figure 5 D shows a comparison between SW01 without notch Nh and SW03 with notch Nh. SW03 allows the thumb to move deeper into the finger sleeve end during a gripping action in an SHWT glove with a selected finger sleeve height (SH) and helps prevent the thumb from being pushed out a distance D compared to SW01.

[0249] The inter-arc bridging wing 216c1 and the two notches Nh on both sides are part of the integrated design of the top skirt SW03. This design helps to address the issue of the thenar eminence 219 protrusion at the base of the thumb. Figure 5 The issue of blocking / distorting the top edge of the skirt is located at position 506, as shown in D. This design also helps the inter-arc bridging wing flip downwards, as... Figure 3 A and Figure 3 The inter-arc bridging wing 216c2 in B is shown.

[0250] Figure 6 A, Figure 7 A, Figure 7 B and Figure 7 C shows another top skirt SW05 with a notched winglet 335. Figure 7 B, in perspective view, shows that the notched wing 335 in SW05 is implemented by extending the notch Nh in SW03 outward to further follow the shape of the thenar eminence protrusion at the base of the thumb.

[0251] Figure 6 B shows that the top skirt SW03 of SHWT glove 100 includes a notch Nh, and the top skirt SW05 of SHWT glove 125 includes a notch flap 335.

[0252] Figure 7A shows the portion where the notched wing 335 and the inter-arc bridging wing 216c1 and their connecting areas (shown in the dashed circle) are integrated to simulate and match the thumb MCP fold 287. Figure 5 (D) and the shape of the base of the thumb, which is the thenar eminence.

[0253] Figure 7 The expanded window of A shows the connecting area in the dashed circle, which simulates and matches the shape of the base of the thumb, while the middle part of the inter-arc bridging wing 216c1 maintains a gap with the palm when the inserted hand is in a relaxed open posture.

[0254] When the hand wearing the SHWT glove is in a clenched position, the inter-arc bridging wing 216c1 may flip downwards, and its internal horizontal portion may, as... Figure 8 As indicated by the upward arrow at the center 007 of the dome in section B, it moves upward toward the palm. The connected notched wing 335 may partially fold outward and gently wrap around the thenar eminence protrusion to avoid pushing or moving the base of the thumb. The integrated design of the notched wing and the inter-arc bridging wing allows for matching the dynamic shape of the thenar eminence and its protrusion in a gripping posture (see...). Figure 15 A. The thenar eminence of the hand when it is in a clenched position (219).

[0255] Inter-arc bridging wing 216c1 is not limited to Figure 1 The SHWT glove 100 shown in Figure A is circular. It can have any shape and appropriate height, as long as it does not affect the usability of the SHWT glove and remains functional. Figure 3 B. Figure 12 C or Figure 12 E provides protection for the specific palm area. Specifically, the shape of the portion of the inter-arc bridging wing 216c1 connected to the notched wing 335 can match the shape of the thenar eminence and its protrusion, such as... Figure 7 The area shown in the dashed circle in section A is an example.

[0256] Add notched winglets 335 on both sides of the inter-arc bridging winglet 216c1. Figure 7 A and Figure 7 (B in the middle) may have a partial structural buffer connection effect, which can make the inter-arc bridging wing 216c1 more likely to flip downward during the gripping action.

[0257] Figure 7 B and Figure 7 The integrated structural design of the notched fin 335 in SW05 shown in C is structurally and functionally similar to the outwardly inclined skirt wall of SW02, but it is only implemented in the area near the base of the thumb (or little finger). Figure 5 At position 506 as shown in D, the rest of the skirt wall remains relatively vertical.

[0258] Figure 7C shows the notched fin 335 of SW05 and the section cut from the outwardly sloping skirt wall of SW02 in the area near the base of the thumb (or little finger). Figure 5 The comparison at position 506 shown in D. Note that if we vertically cut this outwardly sloping wall section from SW02, it will break down into a notch and a fin, as shown in the diagram. Figure 7 As shown in C, its design is similar to the notched wing 335 of SW05.

[0259] SW05 adds notched flaps 335 on both sides of each inter-arc bridging flap 216c1 to follow the shape of the thenar eminence of the left or right hand at the base of the thumb (near the thumb MCP crease 287), while keeping the rest of the skirt edge more vertical. This reduces the overall top skirt opening size and fits the shape of the palm better than SW02.

[0260] In the area near the base of the thumb (or little finger) Figure 5 The notch or notched flap implemented at position 506 as shown in D allows the rest of the skirt wall to extend upwards further, which protects more of the base of the fingers and the palm without causing the thumb or little finger to move upwards a distance D from the end of the finger sleeve when the hand wearing the SHWT glove performs repetitive opening and closing movements.

[0261] Figure 5 The height of position 506 in D roughly corresponds to the height of the base of the user's thumb when the SHWT glove is inserted. The base of the thumb includes the thumb MCP crease 287 and the nearby thenar eminence 219. Therefore, the height of position 506 can be relatively constant. (Reference) Figure 5 and Figure 6 SHWT gloves can be divided into a lower finger protection body (100f) and an upper top skirt (SW03 or SW05). In one aspect, and as... Figure 6 As shown in Figure A, the top skirt (SW03 or SW05) extends upwards above the finger protection body 100f. (Reference) Figure 21 C. Assuming the central connecting area is a flat or convex spherical (dome) structure, and ignoring the wall thickness 505 of the central connecting area, the height 100f-H of the finger protector body 100f is equal to the finger sleeve height (SH). When the finger sleeve height (SH) is similar to or lower than the height of position 506, the notch or notch flap implemented at the height of position 506 can be completely located at the top skirt, such as... Figure 5 , Figure 6 , Figure 17 and Figure 18 As shown in all the examples. When the height of the finger sleeve (SH) is higher than the height of position 506, the lower part of the notch or notch flap may be located at the finger protection body 100f, while its upper part is located at the top skirt (SW03 or SW05).

[0262] The top edge of the SW03 top skirt (which is also the top edge of the SHWT glove) can be reinforced with the top edge rim 107 (in... Figure 1 A and Figure 1 (As shown in B). The thickness of the top edge rim 107 can vary along different sections of the top skirt. By changing the thickness of the top edge rim 107, we can change the stiffness of the top of the SHWT glove, allowing the SHWT glove to stand upright without collapsing.

[0263] The top edge rim 107 and the notched flap 335 also serve another purpose. When a person needs to remove the SHWT glove without the aid of a second hand, the fingers outside the finger cots (usually the ring or little finger) can push against the top edge rim 107 or the notched flap 335 to help pop the finger cots out. Another way to remove the glove is to place the top edge rim 107 against any edge of a fixed object (such as the edge of a kitchen countertop) to help pop the glove out.

[0264] On one hand, the top skirt of the SHWT glove offers superior practicality compared to other gloves on the market due to the addition of notches, notched wings, and reversible inter-arc bridging wings. This top skirt provides enhanced protection for the palm area and the base of the fingers. Furthermore, it prevents the top edge of the skirt from pressing against the thenar eminence at the base of the thumb, helping the SHWT glove stay securely in place.

[0265] Figure 1 A and Figure 1 C shows that the SHWT glove 100 has three identical inverted U-shaped channels 106, which are formed by the inner half of the inner wall of two adjacent finger sleeves and the arched bridge section 108 connecting them. Figure 1 B and Figure 1 D) Formation. When the hand is wearing an SHWT glove, the inverted U-shaped channel 106 is located directly below the root region between the inserted fingers, for example... Figure 8 B. Figure 8 C Figure 12 B and Figure 12 The area at the base of the thumb and index finger shown in D ( Figure 1 B and Figure 1 D). Therefore, the design of the inverted U-shaped channel may affect the performance of SHWT gloves in the finger root region. The inverted U-shaped channel of SHWT gloves has limitations in overall vertical dimensions.

[0266] To explain the vertical dimensions of the inverted U-shaped channel, we define a curve called arc B. Figure 1 D shows one aspect of the longitudinal cross-section 106C of the inverted U-shaped channel of the SHWT glove 100. The longitudinal cross-section 106C is symmetrical along the longitudinal axis and to the UC line of the SHWT glove cross-section, as shown... Figure 1A and Figure 13 The two-dimensional view of C is shown. The top plate of the inverted U-shaped channel is the arch bridge section 108, in Figure 1 D is shown as a cross-sectional view 108C.

[0267] Figure 1 C shows the bottom of the inverted U-shaped channel 106 of the SHWT glove 100, where the outer width 105a is the distance between the two outer corners of the adjacent finger sleeves, and the inner width 105b is the distance between the inner walls of the two adjacent finger sleeves. 105b is parallel to 105a and has the same length as it.

[0268] like Figure 1 As shown in Figure D, to measure the outer width 105a and the inner width 105b, we can assume that the parallel portion of the inner wall 109C extends to the end of the finger sleeve and ignore the curvature of the bottom of the finger sleeve. We call this type of inverted U-shaped channel a parallel inverted U-shaped channel, which can be formed by... Figure 10 A, Figure 10 C Figure 10 D、 Figure 11 B and Figure 13 The finger sleeve shown in Figure C has a cross-section. (As shown in Figure C) Figure 1 As shown in Figure D, we define arc B as a curve that starts from the bottom of one finger sleeve, runs along the longitudinal cross-section 106C, and ends at the bottom of the adjacent finger sleeve. Because Figure 1 The inverted U-shaped channels 106 in D are parallel, so that the arcs B in each longitudinal cross-section 106C along the transverse axis have the same length. Here, the upwardly upright portion of the inter-arc bridging fin is excluded from the longitudinal cross-section 106C.

[0269] Figure 11 A shows an SHWT glove 230 with three inverted U-shaped channels 106n, the outer width 105a and the inner width 105b having different lengths. We refer to this type of inverted U-shaped channel as a non-parallel inverted U-shaped channel, which can be formed by having, for example, Figure 10 B and Figure 10 The finger sleeve is formed by the cross-section shown in E. In this case, each arc B of the longitudinal cross-section (106C) of the inverted U-shaped channel along the transverse axis has a different length.

[0270] like Figure 11 As shown in the diagram on the right side of A, the inner width 105b of the non-parallel inverted U-shaped channel (e.g., those in SHWT gloves 230) is defined as the distance between the two adjacent finger sleeves after their clamping radii (RC) have shifted half an ARC IN segment outwards from their endpoints on the inner wall of the finger sleeve (opposite to the glove center (GC)). The inner width 105b of the parallel inverted U-shaped channel (e.g. Figure 1Those of the SHWT gloves 100 shown in C can follow the same principle to define the internal width 105b by moving half an ARC IN segment from the clamping radius (RC) endpoint on the inner wall of the finger sleeve. Figure 1 As shown in D, the internal width 105b is measured at the glove cross-sectional plane facing the bottom of the finger sleeve, just before the curvature of the finger sleeve bottom begins. Note that in some SHWT glove configurations, the clamping radius (RC) endpoint (opposite to the glove center (GC)) may not be on the inner wall of the finger sleeve. For Figure 10 A, Figure 10 C Figure 10 As shown in Figure D, when the cross-sectional shape of the finger sleeve has an ARC IN segment directly connected to two straight edges, the ARC IN segment can be easily separated and measured. In situations such as... Figure 10 B and Figure 10 In the other cases shown in E, where the ARC IN segment is part of a long arc segment, it can be defined by estimation. In this case, the ARC IN length can be estimated as 1 / 3 of the finger sleeve cross-sectional width (OW), such as... Figure 10 As shown in B.

[0271] For parallel or non-parallel inverted U-shaped channels, the arc B of the longitudinal cross-section 106C located at the inner width 105b can be used as a design reference because the top region of the arc B based on the inner width 105b is the region that may contact or push the base of the fingers (e.g. Figure 15 The location of the base region between the middle and ring fingers (shown in B). In the following description, we can simply refer to arc B, based on an internal width of 105b, as arc B.

[0272] When a person's hand opens and closes, the interdigital arcs MI, MR, and TI (…) Figure 14 The length of the finger creases (shown in D) changes. When the hand is closed and the fingers are bent, the lengths of the finger creases 281, 282, and 283 (as shown in D) change. Figure 14 (as shown in C) and palmar crease 285 and thumb MCP crease 287 (as shown in C) Figure 14 (As shown in D) When the skin is partially or completely folded, it contracts, causing the lengths of arcs MI, MR, and TI to decrease. Here, arc MI represents the arc between the middle and index fingers, arc MR represents the arc between the middle and ring fingers, and arc TI represents the arc between the thumb and index finger.

[0273] Figure 12 B. Figure 12 C Figure 12 D、 Figure 12 E shows a hand wearing SHWT gloves 100 in a clenched position. Figure 8D shows a detailed three-dimensional perspective view of a hand wearing an SHWT glove 100 in a clenched position, with the finger sleeves squeezed together near the ends. To better illustrate the deformation of the finger sleeves, Figure 8 Hands are not shown in D.

[0274] Figure 15 B is a perspective view of the right hand 202b wearing SHWT glove 100 in a clenched position, with the top or arch section 108 of the SHWT inverted U-shaped channel compressed and bent upward toward the root area between the middle finger 213 and the ring finger 214. Figure 15 B shows the base region between the middle finger 213 and the ring finger 214 almost touching the top region of the arc B based on the internal width 105b (see...). Figure 1 C Figure 1 D and Figure 11 A has an internal width of 105b). A similar situation may occur in the base area between the middle and index fingers when each finger is inserted into two adjacent finger sleeves.

[0275] Figure 15 A shows a hand wearing an SHWT glove 100 in a clenched position, using... Figure 2 D shows a typical finger insertion combination, but the SHWT glove 100 is not shown in the figure to better illustrate the hand posture. The minimum lengths of arcs MI, MR, and TI occur when the fingers are pressed together at the fingertips to form a clenched posture, as... Figure 15 A, Figure 15 B. Figure 15 C and Figure 15 As shown in D.

[0276] Here we introduce the projected grip arc as the projected arc of each fingertip arc when the SHWT glove is in a gripped position. Figure 15 C and Figure 15 D shows the projected tight-grip arc MR to represent Figure 14 The projected tight arc of arc MR in D. Following the same representation principle, projected arc MI represents the projected tight arc of arc MI, and projected arc TI represents the projected tight arc of arc TI.

[0277] like Figure 15 C and Figure 15 As shown in D, the projected arc MR is defined as the arc that occurs when the hand performs a clenching motion, causing all the fingertips to come into contact near their ends (see Figure D). Figure 12 B. Figure 12 C Figure 12 D、 Figure 12 E, Figure 15 B and Figure 15 D) The vertical arc length of the projected shape created by the light source from the center SH line of the SHWT glove 100 when the inverted U-shaped channel is squeezed by the middle and ring fingers. Figure 15 C and Figure 15 Figure D shows that when the parallel light source is located at the center SH line of the SHWT glove 100 and the beam direction is along the UC line of the SHWT glove's cross-section, the projection arc MR encloses a shadow area. The length of the projection arc MR can be determined using the light source and its beam direction described above. The same definition and method for estimating the length can be applied to the projection arcs MI and TI.

[0278] The vertical dimensions of the inverted U-shaped channel, based on an internal width of 105b (see...). Figure 1 C Figure 1 D and Figure 11 The length of arc B in A) can have an upper limit. When the length of arc B exceeds this upper limit, the top area of ​​the inverted U-shaped channel may push against the base of the finger and cause the inserted finger to slip out of the finger sleeve.

[0279] When the hand wearing the SHWT 100 glove is in a clenched position and the fingers are fully inserted into the finger cots, all three finger cots are squeezed together (e.g., Figure 12 C Figure 12 D and Figure 12 As shown in E). Interdigital arc (as shown in E). Figure 14 The arcs TI, MI, or MR shown in Figure D are projected to create a projected gripping arc. For example... Figure 15 The inverted U-shaped channel 106 shown in B (e.g., the one between the middle and ring fingers) is deformed, with the top region of arc B, based on the inner width 105b, pressing upward toward the root region between the fingers. On one hand, the length of arc B, based on the inner width 105b, may not exceed the length of the projected clenched arc; otherwise, the top region of arc B may contact and push against the root region between the fingers, causing the fingers to slip out of the finger sleeve.

[0280] Projected grip arcs (e.g., projection arc MI, projection arc MR, or projection arc TI) can have different lengths. Projected arcs MI and MR are typically similar in length, but may be shorter than projection arc TI. When the little finger and thumb each occupy two adjacent finger sleeves in an SHWT glove, the length of projection arc TI may be shorter than the length of the projected grip arc from the little finger through the palm to the thumb. Furthermore, some people may have a longer projection arc MR than projection arc MI, while others may have a longer projection arc MI than projection arc MR.

[0281] On one hand, all inverted U-shaped channels 106 can be identical. In this case, the average length of the projected arc MI and the projected arc MR can be used as an upper limit for arc B based on the inner width 105b.

[0282] Finding the upper limit of arc B based on an internal width of 105b by averaging the lengths of the projected arcs MI and MR can help determine the vertical dimension of the inverted U-shaped channel, which maximizes the size of the object that a hand wearing an SHWT glove can grip between two adjacent finger cots. Here, we refer to the clamping or gripping of an object between two adjacent finger cots or below the inverted U-shaped channel of the SHWT glove as inter-finger grip.

[0283] We use a spherical object as a reference for the arc B length design to describe the size of objects for finger-loop gripping, because a spherical object provides a standard dimensional representation for the size of objects for finger-loop gripping.

[0284] There is no lower limit to the length of arc B. However, the length of arc B determines the largest spherical object that the SHWT glove's finger grip can hold. On one hand, when the SHWT glove's finger grip can hold a spherical object, the ends of two adjacent finger sleeves can extend beyond the equator of the object. This reduces the likelihood of the object slipping. Therefore, if arc B is too short, it may reduce the size of the object that the SHWT glove's finger grip can hold. For simplicity, we have ignored the thickness of the finger sleeve walls here. The thickness of the finger sleeve walls may further reduce the maximum size of the object that the SHWT glove's finger grip can hold.

[0285] The length of arc B can be no greater than (or no more than) but close to the average length of the projected arcs MI and MR, so that the SHWT glove remains fixed during interdigital gripping and can increase the size of objects that the user can grasp using interdigital gripping. This arc B length limitation rule is based on the fact that the maximum size of an object that can be grasped by the bare hand through interdigital gripping is limited by its projected arc MI or projected arc MR. In other words, users with larger hands can grasp larger objects than users with smaller hands.

[0286] To understand the design of the SHWT glove's central gripping space, located directly beneath the palm, we define each finger sleeve as having an approximate curve called arc C. For example... Figure 8 A and Figure 9 As shown in the 3D perspective and 2D view in Figure A, we define arc C as an approximate line starting from the center 007 at the top of the dome, running downwards along the inner wall of the finger sleeve, and ending at the end of the finger sleeve. The center 007 at the top of the dome is the endpoint of the center SH line at the bottom surface of the central connecting area plus the wall thickness 505 of the central connecting area (as shown in Figure A). Figure 21 (As shown in C). The arc C of each finger glove lies in a two-dimensional plane formed by the center SH line of the finger glove and the bottom clamping radius (BRC). There are three arc Cs in the SHWT glove 100. Figure 8A shows three arcs C of the SHWT glove 100, spaced 120 degrees apart, forming a virtual dome space due to rotational symmetry. The virtual dome space has... Figure 8 A, Figure 8 B and Figure 9 A shows the center of the dome's top at 007. The bottom of the dome is a flat surface where the seated object or SHWT glove may stand, and the longitudinal arc of the dome is arc C. The dome height is the height of the center SH line plus the wall thickness of the center connecting area, 505 (e.g., ...). Figure 21 (As shown in C). If arc C is rotated 360 degrees, a virtual dome space can be formed, in which... Figure 8 The bottom clamping radius (BRC) shown in Figure A is the radius of the bottom dome. For example... Figure 9 E and Figure 9 As shown in F, arc C is defined as an approximate line because the bottom curvature of each finger sleeve is ignored, and the bottom segment of arc C is approximated as a vertical straight line. Figure 8 B and Figure 8 C illustrates that the virtual dome space is located below the palm and simulates the shape of the palm when the hand is inserted into the SHWT glove in a relaxed, open position. On the one hand, if the central connecting area and the finger sleeve portion are taken into account, the "virtual dome space" can be represented as an actual physical dome in the SHWT glove.

[0287] When the hand is in a clenched position, such as Figure 8 D、 Figure 12 B. Figure 12 C Figure 12 D and Figure 12 As shown in E, all three finger cots are squeezed together. Figure 8 As indicated by the upward arrow at the center 007 of the dome in section B, the top of the virtual dome space or the virtual dome panel will be squeezed upward toward the palm at the central connecting area, together with the top of the inverted U-shaped channel 106.

[0288] The length of arc C may have an upper limit; otherwise, the virtual dome plate at the central connecting area 103 and the inverted U-shaped channel connected thereto may push the palm during the gripping action and cause the fingers to slip out of the SHWT glove. Figure 8 Two-dimensional view in E or Figure 12 B. Figure 12 D and Figure 12 The 3D view in E shows the hand in a clenched position, with the fingers squeezed together. See also: Figure 15 B SHWT gloves 100 grip deformation shape, because arc B together with arc C affects the usability of SHWT gloves during gripping.

[0289] To better describe the upper bound of arc C, we use Figure 2 A and Figure 2Figure B shows an example of how to wear SHWT gloves 100. Figure 2 A and Figure 2 In option B, the thumb is inserted into the first finger sleeve, the index and middle fingers into the second finger sleeve, and the ring and little fingers into the third finger sleeve.

[0290] Figure 15 A shows when the hand is in Figure 15 B or Figure 12 B. Figure 12 D and Figure 12 When gripping as shown in E, and Figure 2 A and Figure 2 B is the same as the above-mentioned finger insertion combination (SHWT glove 100 is not shown in the figure). Figure 15 A. The SHWT gloves have been omitted from the attached diagram to better illustrate the finger and palm positions. We will... Figure 15 The clenched arc C shown in A is defined as a curve from the tip of the folded fingers to the center of the arched palm connection area (shaded area), which is located just below and close to the base of the middle finger. When the hand is in a clenched position, this shaded area overlaps with the central connection area 103 of the SHWT glove 100.

[0291] 3D simulation and measurement of the SHWT glove 100 prototype verified that when the hand wearing the SHWT glove 100 is in a relaxed open or clenched position, the central connection area 103 of the SHWT glove ( Figure 15 The shaded area in the image is roughly located in Figure 14 The palm area below the base of the middle finger, as shown in D, with the hand placed flat.

[0292] exist Figure 14 In step D, with your hand flat, imagine your index and middle fingers straight and together, while simultaneously rotating your thumb clockwise to approximately 120 degrees and your ring and little fingers counterclockwise to approximately 120 degrees. This simulates... Figure 2 A and Figure 2 B is the same exemplary finger insertion combination. When the fingers are extended in the imagined virtual posture described above, the distances from the tips of the thumb, middle finger, and ring finger to the center of the shaded area are approximately the same, and this shaded area overlaps with the central connecting area 103. We refer to this distance as the "flat-hand arc radius," as... Figure 14 As shown in D. This is Figure 14 The radius of the larger circle in D is the center of the shaded area.

[0293] When the hand wearing the SHWT glove is in a clenched position and all the finger cots are squeezed together... Figure 14 C and Figure 14 All finger folds 281, 282, 283, 287 and palm fold 285 in D will be folded, and the surrounding skin will contract.

[0294] The radius of the arc of a flat hand will decrease to that of a tightly clenched hand (e.g.) Figure 15 The gripping arc C (as shown in Figure A). Figure 14 D shows that the approximate difference between the radius of the flat arc and the tight arc C is the contraction distance SD.

[0295] Figure 14 D shows that the clenching arc C of the middle finger is straight, while the clenching arc C of the thumb and little finger is curved, but they are roughly the same length.

[0296] Therefore, return Figure 15 A shows a three-dimensional illustration of the length of the clenched arc C, illustrating how this length changes due to the folding of the fingers and palm and the contraction of the skin when the hand is in a clenched position. Figure 14 It comes from the reduction of the "flat arc radius" of D.

[0297] On the one hand, the length of arc C can not exceed the length of the tightly clenched arc C; otherwise, when the hand wearing the SHWT glove is in a tightly clenched posture, the top of the central connecting area 103 of the SHWT glove and the inverted U-shaped channel 106 may bend upwards (e.g., Figure 8 (As indicated by the upward arrow at the center 007 of the dome in section B) and push your palm, which may cause the SHWT glove to slip off.

[0298] Finding the grip arc C as the upper limit of arc C not only helps prevent fingers from slipping out of the SHWT glove during gripping, but also helps determine the arc C that maximizes the size of the object that the hand wearing the SHWT glove can grip firmly with all finger sleeves in the center. Here, we refer to the object gripped in the center between all finger sleeves of the SHWT glove as the SHWT glove center grip.

[0299] On one hand, we use a spherical object as a reference for the arc C length design to describe the size of the object that the center grip of the SHWT glove can hold, because the spherical object provides a standard dimensional representation of the object size that the center grip of the SHWT glove can hold.

[0300] Figure 8 A, Figure 8 B and Figure 8 C illustrates the virtual dome space within the SHWT glove inserted beneath the palm of the hand. The size (or volume) of this virtual dome space varies with the length of the bottom grip radius (BRC) as the hand opens and closes, but the fixed arc length C determines the maximum size of a spherical object that the SHWT glove's central grip can hold. For the SHWT glove's central grip to hold a spherical object, the ends of all finger sleeves can extend beyond the equator of the spherical object. Otherwise, the object may slip off. Therefore, the longer the arc length C, the larger the spherical object that the SHWT glove's central grip can hold.

[0301] For simplicity, we have omitted the thickness of the finger sleeve walls here. The thickness of the finger sleeve walls may further reduce the maximum object size that the SHWT glove's central grip can hold.

[0302] On the one hand, the length of arc C can not exceed but can be very close to the grip arc C so that the SHWT glove remains fixed during the center grip, while increasing the size of the object that the user can grip with the center grip of the SHWT glove.

[0303] On the one hand, arcs C and B can follow the guidelines described herein to ensure that the SHWT glove fits securely to the hand without slipping during use, while also maximizing the size of objects that the SHWT glove's finger-to-finger grip and center grip can hold.

[0304] On the one hand, the inverted U-shaped channel space between the SHWT finger sleeves (including the lower part of the inter-arc bridging wing) and the central dome space determined by the selected arcs B and C can increase the protection area for the base of the fingers and the palm, and improve the fit to the outer interdigital base area.

[0305] Similar to Figure 1 A and Figure 1 The SHWT glove 100 in B is an SHWT glove with a palm protection section, which includes a central palm protection section and a top skirt. The central palm protection section includes an arch section 108 ( Figure 1 B) Partial horizontal section of the inter-arc bridging winglet 216c1 (such as...) Figure 1 (as shown by the dashed circle in B) and Figure 1 B and Figure 1 The central connecting region 103 in D. The central palm protection segment can be as follows: Figure 1 B. Figure 2 A, Figure 2 D、 Figure 5 B. Figure 8 A, Figure 8 B or Figure 8 C shows the protected center of the palm and the inner root section of the fingers from different perspectives.

[0306] Top skirt, for example, has Figure 5 A or Figure 3 The upward section of the inter-arc bridging wing 216c1 of C. Figure 5 , Figure 6 and Figure 7 SW03 or SW05 in the formula can further protect the base of the fingers and the rest of the center and edge areas of the palm. Figure 3 B. Figure 5 D and Figure 7A). The outward-flipping inter-arc bridging fin 216c2 can protect... Figure 3 B. Figure 12 C and Figure 12 The palm area between the thenar eminence 219 and the hypothenar eminence 217 shown in E.

[0307] For simplicity, the complete palm protection section, including the central palm protection section and the top skirt, will be referred to simply as the palm protection section.

[0308] The palm protection section is an integrated extension of the finger sleeve opening at the top of the finger sleeve. Figure 2 D、 Figure 3 C Figure 3 B. Figure 4 A, Figure 12 C and Figure 12 E shows how the hand protection section can protect the hand from different angles and postures.

[0309] Figure 8 A, Figure 9 A and Figure 9 E shows three-dimensional and two-dimensional views of the SHWT glove 100. The longitudinal axis of each finger sleeve connected to the palm protection segment is orthogonal or nearly orthogonal to the cross-sectional plane of the SHWT glove. Therefore, refer to... Figure 8 A. The size of the palm protection zone can be determined by the bottom clamping radius (BRC) of the SHWT glove and the distance between the bottom finger sleeves of two adjacent finger sleeves (ISD) or the width of the inverted U-shaped channel. Throughout the description, the bottom clamping radius (BRC) will be used when discussing the clamping radius (RC) related to the size of the SHWT palm protection zone. Figure 8 A, Figure 9 E and Figure 9 F is shown).

[0310] like Figure 8 As shown in Figure A, the bottom finger gap distance (ISD) is the distance between the endpoints of two adjacent bottom clamping radii (BRCs) (opposite to the glove bottom center (GBC)). In a rotationally symmetric SHWT glove, two adjacent bottom clamping radii (BRCs) and the ISD form an isosceles triangle.

[0311] refer to Figure 8 A and Figure 16C. In a three-finger-based SHWT glove, two adjacent bottom grip radii (BRCs) have a 120-degree angle, so the lengths of the bottom grip radius (BRC) and ISD can be calculated and converted between each other. The same applies to four-finger-based SHWT gloves, where two adjacent bottom grip radii (BRCs) have a 90-degree angle to convert between the bottom grip radius (BRC) and ISD. The bottom grip radius (BRC) length can affect the center grip performance of the SHWT glove, as it is a threshold for determining whether the SHWT glove needs to open or close to center-grip spherical objects of different radii.

[0312] When the radius of a spherical object is greater than the bottom grip radius (BRC), the user needs to open the SHWT glove before grasping the object. If the radius of the spherical object is smaller than the bottom grip radius (BRC), the user can close the SHWT glove to grip the object on the smaller object without opening the SHWT glove.

[0313] As a reasonable approximation and ignoring the finger sleeve wall thickness, the ISD minus the width of two and a half finger sleeves is approximately equal to Figure 1 The outer width 105a or inner width 105b of the inverted U-shaped channel 106 in the SHWT glove 100 shown in Figure C is determined by the fact that the ISD terminates at the two bottom clamping radius (BRC) endpoints on the inner wall. The ISD can be used instead of the inverted U-shaped channel width to explain the palm protection section dimensions, since non-parallel inverted U-shaped channels may have different widths (see Figure C). Figure 11 (Outer width 105a and inner width 105b in A).

[0314] Once the cross-sectional width of the finger sleeve at the bottom finger sleeve section of the SHWT glove is determined, the ISD is used as a threshold to determine whether an opening or closing action is required between two adjacent finger sleeves to grasp spherical objects of different diameters, similar to how the bottom grip radius (BRC) is used as a threshold for grasping objects at the center.

[0315] When the diameter of a spherical object is greater than ISD minus the width of two and a half finger cots (approximately equal to the width of the inverted U-shaped channel), a user wearing SHWT gloves can open the SHWT gloves to grip the object. If the diameter of the object is less than ISD minus the width of two and a half finger cots, a user wearing SHWT gloves can close the SHWT gloves on the object to grip it without opening the SHWT gloves.

[0316] Geometrically, either the bottom grip radius (BRC) or the inter-finger distance (ISD) can represent the finger-to-finger grip and center grip performance of SHWT gloves, as ISD and bottom grip radius (BRC) values ​​are translatable (see [link to relevant documentation]). Figure 8 A and Figure 16 C).

[0317] In such Figure 13 A and Figure 13 In the case of the SHWT glove 250 based on four-finger cots shown in B, there may be a distance between the finger cots (the distance between two non-adjacent finger cots), which can be twice the length of the bottom clamping radius (BRC). Therefore, the original bottom clamping radius (BRC) or ISD can still determine the size of the palm protection area.

[0318] Figure 8 B and Figure 9 E illustrates that, for a selected palm protection segment and a fully inserted right hand 202b in a relaxed, open position, in Figure 9 The upper dashed box above E shows the upper section of arc C of the solid curve D and the arch bridge section 108 (see...). Figure 1 D) formed a virtual dome panel below the palm.

[0319] Figure 8 B. Figure 9 A and Figure 9 E shows the inner wall of the finger sleeve's top opening curving toward a virtual dome plate centered on the upper segment of arc C, the curvature of which follows the curvature of the parallel-inserted index and / or middle fingers in a relaxed, open posture. Figure 8 B).

[0320] Note: The shape of the virtual dome plate centered on the upper section of arc C follows the shape of the inserted index and / or middle fingers, but it may also follow the average open and relaxed shape of all four inserted fingers (excluding the thumb) in the SHWT glove.

[0321] Figure 8 C illustrates the possible gap space 288 between the upper section of arc C and the relatively vertically inserted thumb. This is unavoidable in rotationally symmetric SHWT gloves. If we make the upper section of arc C a curve closer to a 90-degree angle (e.g., ...), ... Figure 9 If the curve shape DH in E is used to reduce the gap space 288, it may conflict with the curvature of the other four inserted fingers in a relaxed, open posture. We also do not want the upper segment of arc C to be closer to a straight line, for example... Figure 9 The curve shape DL in E may produce a larger gap space 288 (see...) Figure 8 C and Figure 9 E). The desired range of the upper segment of arc C can roughly follow the average curvature of the four inserted fingers (excluding the thumb) in a relaxed, open posture, with some deviation allowed, but not as... Figure 9 The curve shape shown in E deviates as much as DH or DL.

[0322] Therefore, the selected arc C length and the relatively constant upper segment curve shape of arc C ( Figure 9 The solid curve within the upper dashed box (E) plus its relatively vertical lower section can be used to determine... Figure 8 A and Figure 9 The relatively constant distance VD is shown in E. When analyzing the geometric relationships between arcs C, VD, SH, and BRC (e.g., Figure 9 E and Figure 9 When considering arc C at the height of the top starting point (center 007 of the dome top, as shown in F), we can assume that arc C is at the height of the top starting point (center 007 of the dome top, as shown in F). Figure 9 As shown in Figure A, the height of the center SH line or the height of the finger sleeve (SH) is ignored, ignoring the wall thickness of the center connection area 505 (e.g., Figure 21 (as shown in C), because the wall thickness of 505 is negligible compared to the length of SH.

[0323] Figure 8 A and Figure 9 E illustrates that the VD (Video Depth), bottom clamping radius (BRC), and center SH (Silver Slip) line form a right-angled triangle. Since the length of VD remains relatively constant, it limits the lengths of the center SH line and the bottom clamping radius (BRC), making them inversely proportional. This means that the longer the center SH line, the shorter the bottom clamping radius (BRC), and vice versa. On one hand, the finger sleeve height (SH) is the length along the center SH line from the center of the glove bottom (GBC) to the bottom surface of the center connection area. On the other hand, the length of the center SH line can be equal to the finger sleeve height (SH).

[0324] Figure 9 F shows that for a relatively constant VD length determined by arc C (whose upper segment curve shape D) or an arc Cb of similar length with a similar upper segment curve shape Db, the inversely proportional length SHb will be greater than the original fingertip height (SH) as the bottom clamping radius (BRC) decreases to BRCb. The abbreviation "arc Cb" refers to the arc C line of the SHWT glove, which has a similar length and a similar upper segment curve shape (or dome shape) to the arc C line of the compared SHWT glove. The abbreviation "BRCb" refers to the bottom clamping radius (BRC) of the SHWT glove, which is smaller than the bottom clamping radius (BRC) of the compared SHWT glove. The abbreviation "SHb" refers to the fingertip height (SH) of the SHWT glove, which is greater than the fingertip height (SH) of the compared SHWT glove.

[0325] Based on Figure 8 A, Figure 8 B. Figure 8 C Figure 9 E and Figure 9The above analysis of the two-dimensional and three-dimensional dimensional parameters of the SHWT glove 100 shown in F, under the constraint of a relatively constant VD length, shows that the size of the palm protection area can be determined by the inversely proportional bottom gripping radius (BRC) and finger sleeve height (SH) and their relative ratios. The size of the palm protection area may affect the clamping / gripping performance of the SHWT glove.

[0326] To determine the bottom gripping radius (BRC) and finger sleeve height (SH) of the palm protection section, we need to understand how a gloved hand moves and exerts force to perform gripping / grasping actions. When a hand is wearing a conventional glove, the hand, especially the muscles driving the finger joints, may use additional force to open and close because force is required to bend and stretch the body of the conventional glove or SHWT glove to follow the hand (finger) movements. These additional forces used to deform the conventional glove are one of the main factors contributing to usability issues and hand discomfort associated with conventional gloves.

[0327] Hand muscles, especially those near the finger joints, exert more force during closing movements than during opening movements. Hands wearing SHWT gloves experience muscle weakness or fatigue more easily when opening than when closing to form a clenched fist. When the hand in an SHWT glove closes to grasp a small object, such as... Figure 8 As shown in D, the hand primarily uses additional force to bend and squeeze the SHWT glove body or clamp the finger cots in order to reach and hold small objects (see Figure D). Figure 8 D). The additional force used during the closing action will be referred to as the additional closing force, and will be primarily dominated by the force used to bend and squeeze the SHWT glove to pick up small objects (which will be referred to as the additional bending force).

[0328] When the hand in the SHWT glove needs to open to grasp a large object, the hand first uses additional force to bend the finger sleeves outward, then stretches / expands the palm protection section and the entire SHWT body structure until the SHWT glove reaches its structural stretch / expansion limits based on arcs C and B. We will discuss these structural stretch / expansion limits based on arcs C and B in detail later. The additional force used during the opening action will be referred to as the additional opening force.

[0329] Additional opening forces involve different types of forces. One is the additional bending force that flexes the finger sleeves and palm protection section outwards. Another is the additional stretching / expansion force that further stretches / expands the entire SHWT body structure; this will be referred to as additional stretching force. The additional stretching force will be greater than the additional bending force that occurs during hand closure or opening movements. Human hand physiology, such as weaker muscle strength during hand opening movements within the glove, and the smaller additional bending force versus the larger additional stretching force, are some factors guiding SHWT glove design. The design of the palm protection section's structure and dimensions creates a palm protection section size that can potentially accommodate a wider range of hand geometries and physiology.

[0330] On one hand, the structural dimensions of the palm protection section are designed to maximize the distance between finger sleeves within the constraint of finger sleeve height (SH). Increasing the ISD or bottom grip radius (BRC) can increase the size of objects (assuming a sphere) that the SHWT can grasp using only a closing motion. On the other hand, it can reduce the likelihood that the SHWT needs to open its arms to grasp larger objects. Since the bottom grip radius (BRC) and finger sleeve height (SH) are inversely proportional, a longer bottom grip radius (BRC) results in a shorter finger sleeve height (SH). A shorter finger sleeve height (SH) may lead to other usability issues discussed below. On the other hand, the finger sleeve height (SH) can be determined first, thus deriving the bottom RC (BRC) length.

[0331] On one hand, the structural dimensions of the palm protection section are designed to avoid, delay, and reduce the large additional tensile forces during the opening and closing motion of the SHWT. To determine the structural dimensions of the palm protection section that help reduce the force exerted by the user's hand during the opening and closing motion of the SHWT, we can analyze the movement of the finger joints during the opening and closing motion of the SHWT.

[0332] To analyze the finger joint movements during hand opening and closing actions, we will use a method of wearing SHWT gloves as an example, such as... Figure 2 A, Figure 2 B and Figure 2 As shown in SHWT Glove 100 in D: the thumb is inserted into the first finger sleeve alone, the index and middle fingers are inserted into the second finger sleeve in parallel, and the ring and little fingers are inserted into the third finger sleeve in a non-parallel manner.

[0333] Figure 8 C illustrates an example of how the thumb and index finger joints move during the opening and closing of the hand. The thumb and index finger joints are used to illustrate finger movement because the thumb, index finger, and middle finger play a dominant role in the opening and closing of the hand.

[0334] We omit the movement of the middle finger because a parallel-inserted middle finger may have similar PIP and DIP movements to the index finger. A non-parallel-inserted ring and little finger may have similar joint movements to the index finger.

[0335] To help reduce the force exerted by the user's hand during the opening action of the SHWT glove, we analyzed the stages of the opening process, the associated additional opening forces, and the structural deformation characteristics of the SHWT glove.

[0336] During the hand-opening action in a selected SHWT glove, the hand begins from its initial position until the maximum opening limit of the SHWT glove is reached, which is the structural tensile / expansion limit based on arcs C and B. We can divide the hand-opening action into two phases.

[0337] In the first phase (see Figure 2 A and Figure 8 (C) All five fingers are extended by pivoting the PIP, T-MCP, and T-DIP joints outward to their maximum extent. Correspondingly, the palm protection segment of the SHWT glove flexes outward to separate the ends of all finger sleeves. The remaining four MCP joints (excluding the T-MCP) and the CMC joint do not have major pivoting movement. Therefore, the palm protection segment may not expand, and a major stretching force may not be required at this stage. We call this stage the first PIP, T-MCP, and T-DIP opening stage. This stage may be dominated by relatively small additional bending forces to flex the finger sleeves and palm protection segment outward in an SHWT glove with a selected finger sleeve height (SH), thereby separating all finger sleeves (especially near the ends).

[0338] The end characteristic of the first stage of the SHWT Glove 100 hand opening is that all five fingers are extended by pivoting the PIP, T-MCP, and T-DIP joints outward to their maximum extent, and the hand opening posture has approached or may begin to stretch / expand the SHWT glove based on the structure of arcs C and B, while the four MCPs (excluding the T-MCP) and CMC joints still maintain their relaxed opening angle.

[0339] In the subsequent second phase, the MCP and CMC joints undergo further small outward pivoting movements to help the hand open further to stretch the SHWT glove (including the palm protection segment) and ultimately reach the structural tensile / expansion limits based on arcs C and B. This phase can be referred to as the second MCP and CMC opening phase. The second MCP and CMC opening phase may be dominated by a larger additional tensile force.

[0340] We define the hand posture at which the structural stretch / expansion limits based on arcs C and B are reached as the SHWT glove hand maximum open posture. The SHWT glove hand maximum open posture is characterized by all five fingers being extended at the PIP, T-MCP, and T-DIP joints, with the MCP and CMC joints at their maximum open angles, and the interdigital distance (especially at the fingertips) reaching its maximum.

[0341] As mentioned earlier, the tight grip arc C may not exceed the radius of the flat grip arc (see...). Figure 14 D、 Figure 15A). Since arc C may not exceed the clenched arc C, arc C may not exceed the flat-hand arc radius. This results in the maximum open position of the SHWT glove hand in the selected SHWT glove never exceeding the flat-hand arc radius and being limited by structural stretch / extension limits based on arcs C and B. Therefore, after all PIP, T-MCP, and T-DIP joints are fully open and extended, the further opening angles of the four MCPs (excluding T-MCP) and CMC joints will be limited by structural stretch / extension limits based on arcs C and B. In other words, in the maximum open position of the SHWT glove hand, the maximum opening angle of the four MCPs (excluding T-MCP) and CMC joints will be smaller than their opening angle in a flat-handed hand. This is why, in the second opening phase, in the selected SHWT glove, the MCP and CMC joints require only small angle changes from the relaxed opening angle to the maximum opening angle.

[0342] On the one hand, there may be overlap between the opening phases of the first PIP, T-MCP, and T-DIP and the opening phases of the second MCP and CMC. These two phases may overlap, but the first phase is dominated by the movement of the PIP and T-MCP joints, while the second phase is dominated by the movement of the MCP and CMC joints.

[0343] To perform opening and closing movements in an SHWT glove, the finger joints can move in different combinations and sequences. Here, we list three typical combinations and sequences of finger joint movements, where the SHWT glove... Figure 8 C and Figure 8 Begin with the hand in a relaxed, open position as shown in Figure B, focusing on the opening motion of the hand.

[0344] Figure 8 C illustrates the pivoting motion and range of motion (dashed lines) of each finger joint in the SHWT glove 100, represented by the thumb and forefinger. Understanding these three cases may help in designing an SHWT glove that reduces the force required for the user's hand to open the SHWT glove during use.

[0345] Case A is a common finger joint movement combination in SHWT gloves, particularly for hand opening movements. All PIP, T-MCP, and T-DIP joints pivot to perform the opening and closing motion; the CMC and the remaining MCPs move almost no further, except during the opening phase of the second MCP and CMC. (Reference) Figure 8 C. T-DIP 261 may have a greater pivoting motion than T-MCP joint 271. For the other four fingers, the pivoting motion of the PIP joint may also be accompanied by a smaller pivoting motion of the DIP joint.

[0346] Case A is characterized by the fact that the opening and closing of the hand mainly relies on the pivoting motion of the four PIP joints as well as the T-MCP and T-DIP joints, while the CMC and MCP joints hardly move unless a second MCP and CMC opening phase is performed to reach the structural tensile / expansion limit based on arcs C and B.

[0347] The opening action in scenario A will follow the two-stage opening process described above: a first PIP and T-MCP opening stage, and a second MCP and CMC opening stage involving the CMC and MCP. It should be noted that the opening sequence from the PIP, T-MCP, and T-DIP groups to the MCP and CMC groups in scenario A can differ, and there are no clear boundaries, but the final finger posture and the additional opening force generated may be similar. For example, the PIP, T-MCP, and T-DIP opening stage may also be accompanied by a small MCP and CMC opening stage. Then, before all five fingers are fully extended at the PIP, T-MCP, and T-DIP joints, the MCP and CMC joints may first reach near the stretch / extension limits of the hand's protective structures.

[0348] During the opening phase of the MCP and CMC, the stretching / expansion limits of the hand's protective structures may be reached first, which could lead to the completion of full extension of all five fingers by all PIP, T-MCP, and T-DIP joints, while the MCP and CMC joints eventually open to reach the stretching / expansion limits of the structures based on arcs C and B.

[0349] Case B is mainly used for closing actions. (See reference) Figure 2 A and Figure 8 C. During the closing action, pivoting may occur at the four MCPs (excluding the T-MCP), CMC, and possibly T-DIP 261. All four PIP joints (292, 293, 294, and 295) and the T-MCP joints undergo almost no pivoting and maintain their flexion angle in the relaxed open position.

[0350] Although the hand may be limited by the structural tensile / expansion limits of the palm protection segment and may not reach the structural tensile / expansion limits based on arcs C and B, the hand can still open through the four MCPs (excluding the T-MCP) and CMC joints as in Case B, while keeping all PIP and T-MCP joints in a relaxed open position and maintaining their flexion angles. Unless the first PIP and T-MCP opening phase is involved and until all four fingers are extended, the hand may not reach the maximum open position of the SHWT glove hand.

[0351] Unlike the structural tensile / expansion limits based on arcs C and B, the structural tensile / expansion limits of the hand protection zone can include the maximum tensile limits of the perimeter of the central hand protection area and the outer skirt wall of the top skirt (including the inter-arc bridging flaps).

[0352] To further open, and before the four MCPs and CMCs open to the structural tensile / expansion limit of the palm protection segment, all PIPs, T-MCP joints 271 and T-DIPs 261 pivot to straighten outward, thereby separating the ends of all finger sleeves until they reach the structural tensile / expansion limit based on arcs C and B.

[0353] Case B is characterized by hand closure primarily relying on the four MCPs (excluding the T-MCP) and CMC joints, accompanied by small T-DIP pivoting movements, while all PIP and T-MCP joints 271 are held at a relaxed opening angle. The opening movements to achieve the maximum open position of the SHWT glove hand in Case B are the same as in Case A, with the same combination and sequence of finger joint movements.

[0354] Case C is similar to Case B, using the pivoting movements of the four MCPs (excluding the T-MCP) and CMC joints to achieve the opening and closing motion, but it will begin with the movement of the four PIP joints to straighten the fingers. The T-DIP may participate in the pivoting motion during the closing motion.

[0355] The finger joint movements in Case C primarily occur with bare hands or when the hand is in a regular five-finger glove. Case C may not occur frequently in SHWT gloves, but some people will straighten their PIP joints before using the four MCPs (excluding T-MCP) and CMC joint pivoting movements to perform hand opening and closing movements in SHWT gloves. Case C is characterized by the hand opening and closing movement beginning in a relaxed open position with the PIP and T-MCP joints straightened outward, followed by pivoting movements of the four MCPs (excluding T-MCP) and CMC joints similar to Case B, and a small T-DIP pivoting movement used only for closing movements. The opening movement in Case C is similar to Case A, with a first PIP and T-MCP opening phase, and a second MCP and CMC opening phase involving the CMC and MCP.

[0356] As described, the closing action in cases A, B, and C ends with the fingers squeezing together near the tip, as... Figure 12 B. Figure 12 C Figure 12 D、 Figure 12 E and Figure 15 As shown in B. For the final closed shape and posture of the hand inside the SHWT glove, please refer to [reference needed]. Figure 15 A, Figure 15 C and Figure 15D (SHWT glove 100 is not shown in the figure to better illustrate hand posture).

[0357] In cases A, B, and C, the opening / closing of the hand in the SHWT glove 100 exhibits corresponding deformation characteristics of the SHWT glove's main structural features, which can be summarized as follows: 1) The opening motion of the four MCPs (excluding the T-MCP) and CMC joints may primarily expand the palm protection segment first, then expand the entire SHWT glove based on arcs C and B, which may result in large additional tensile forces. The pivoting motion of the closing motion of the four MCPs and CMC joints may primarily flex the palm protection segment, which may result in the hand requiring only small additional flexing forces. In the closing motion of case B, the four MCPs (excluding the T-MCP) and CMC joints may cause... Figure 8 The virtual dome plate shown in B bends / compresses upward toward the palm. The opening action performed in cases A, B, and C via the four MCPs (excluding the T-MCP) and CMC joints may cause the virtual dome plate to move downward and stretch the top edge and skirt wall of the palm protection section, the finger protection body 100f.

[0358] 2) The opening or closing motion of all PIP and T-MCP joints may primarily involve bending or squeezing the SHWT glove at a selected palm protection segment with a selected finger sleeve height (SH). If the finger sleeve height (SH) is not within the selected range, for example when the finger sleeve height (SH) is lower than the PIP and T-MCP joint height, their opening motion may involve additional tensile forces stretching the palm protection segment, which will be discussed in more detail later. By selecting the palm protection segment size, we can reduce the additional tensile forces during the opening phase of the PIP and T-MCP.

[0359] 3) Any pivoting movement of the DIP joint during the closing action can help the DIP protrusion 80° (in Figure 8 B and Figure 8 (C) Further squeezing the relatively straight finger sleeve wall to increase the clamping force of the finger sleeve may help prevent the finger sleeve from slipping off the inserted finger.

[0360] Based on the above analysis of the finger joint movements during the opening and closing action of the hand and the small additional bending force and large additional stretching force generated by them that deform the SHWT glove, we can find a finger sleeve height (SH) that allows the PIP and T-MCP joint opening actions to primarily bend or compress but not stretch / expand the SHWT glove body, in order to reduce the large additional stretching force.

[0361] After determining the finger sleeve height (SH), it can be based on Figure 9The right-angled triangle relationship between the finger sleeve height (SH), bottom clamping radius (BRC), and constant VD shown in E determines the size of the palm protection segment.

[0362] The following discussion addresses how the selected palm protection segment dimensions prolong the first PIP and T-MCP opening phase and delay the second MCP and CMC opening phase by keeping the relaxation opening angles of the MCP and CMC joints close to their opening angle limits in the SHWT glove. The opening angle limits of the MCP and CMC in the SHWT glove are limited by structural tensile / expansion limits based on arcs C and B.

[0363] Keeping the relaxation opening angle of the MCP and CMC close to their opening angle limits in the SHWT glove is one factor that may be needed to delay or reduce the large additional tensile force during the second MCP and CMC opening phase.

[0364] To reduce the additional tensile force exerted on the palm protection segment by the hand during the PIP and T-MCP opening phases, the selected finger sleeve height (SH) can be close to the range between the average height of the PIP joint and the height of the thumb T-MCP joint when the hand is fully inserted into the SHWT glove in a relaxed open position. Figure 8 B and Figure 8 As shown in C. The selected finger cot height (SH) can deviate from this range. Height 100f-H (in Figure 5 B. Figure 15 E and Figure 21 C) equals the selected finger sleeve height (SH) plus the wall thickness of the central connecting area 505 (e.g. Figure 21 As shown in C). The height of the center 007 at the top of the dome ( Figure 8 (A) equals the selected finger sleeve height (SH) plus the wall thickness of the central connecting area 505 (e.g.) Figure 21 (as shown in C).

[0365] Figure 2 B. Figure 5 D、 Figure 6 A, Figure 8 B and Figure 8 C shows the relative position of the finger joints to the finger height (SH) of the SHWT glove when the finger height (SH) is within the range between the average height of the PIP joint and the height of the thumb T-MCP joint. Figure 5 D and Figure 8 B shows the index finger crease 282 below the height of the finger sleeve (SH). Figure 5 D and Figure 8 The height of the finger sleeve (SH) is not shown in B. See [reference needed]. Figure 8A sample of finger sleeve height (SH) is shown), and the I-PIP joint 292 is at (or approximately at) the finger sleeve height (SH) (see [reference]). Figure 8 B and Figure 8 C). Figure 2 B. Figure 5 D、 Figure 6 A, Figure 8 B and Figure 8 C shows that the same situation applies to PIP joints 293 and 294, whose height is close to the finger sleeve height (SH) (see Figure 2 A. Understand joint numbering. Figure 8 C shows that the height of the inserted T-MCP joint 271 is higher than the average PIP, but not far from the finger sleeve height (SH).

[0366] refer to Figure 5 D、 Figure 6 A, Figure 8 B and Figure 8 C. The top skirt of the SHWT glove (including the SW03 notch or SW05 notch flap) can cover all PIPs (see [link]). Figure 2 A, Figure 2 B, but P-PIP 295 is not shown in the figure). Part of the top skirt wall and the notch or notch wing in SW03 or SW05 can create additional space for the thenar eminence of the T-MCP joint 271 and above it (see Figure 5 D、 Figure 6 A and Figure 7 A).

[0367] During the first PIP and T-MCP opening phase, each finger cot can be driven outward by the pivoting motion of the PIP and T-MCP joints of the inserted finger. In SHWT gloves where the finger cot height (SH) is between the average height of the PIP joint and the height of the thumb T-MCP joint, the pivot point of the finger cot during the movement of the PIP and T-MCP joints can be close to the pivot point of the PIP joint (see [link to glove description]). Figure 8 B and Figure 8 C). When the finger sleeve height (SH) closely matches the pivot points of the average PIP and T-MCP joints, the user's hand may only require additional bending force to flex the palm protection segment and open the finger sleeve outward.

[0368] Although the T-MCP joint is located above all PIP joints (see...) Figure 8 (C) It remains close to the aforementioned finger cuff height (SH), and the force that moves it outward is still dominated by additional bending force, with not much additional stretching force. This is because the outward movement of the thumb involves two joints, the T-MCP and the T-DIP, therefore the outward movement range of the T-MCP is smaller than... Figure 8All PIPs shown in C. Additionally, the T-MCP is located near the notch or notch flap area of ​​the top skirt, which provides extra space to avoid stretching the skirt wall, even though it is close to the thenar eminence area.

[0369] SHWT gloves, with a finger sleeve height (SH) within the range of the average height of the PIP joint and the height of the thumb T-MCP joint, allow these joints to use small additional bending forces during opening movements and avoid potentially large additional tensile forces that could deform the palm protection segment. Figure 8 The dome top center 007 shown in A may move up and down during the opening and closing action, but the force applied to the central connecting area is likely to be primarily a bending force.

[0370] If the finger sleeve height (SH) is lower than the average height of all inserted finger PIP joints, for example, if the finger sleeve height (SH) is near the midpoint between I-PIP and I-DIP (see... Figure 8 C and Figure 15 The SHL of the hand (PIP joint opening and pivoting motion) may stretch / expand the palm protection segment, thus causing the hand to use additional stretching force.

[0371] Figure 15 E illustrates that, with reference to the dimensions of the finger protector body 100f, when the bottom clamping radius (BRC) increases to BRCL, the finger sleeve height (SH) will decrease to SHL. The abbreviation "BRCL" indicates the bottom clamping radius (BRC) of an example SHWT glove, which is larger than the bottom clamping radius (BRC) of a comparable SHWT glove. The abbreviation "SHL" indicates the finger sleeve height (SH) of an example SHWT glove, which is smaller than the finger sleeve height (SH) of a comparable SHWT glove. The reduced SHL may force the upper section of arc C to become flatter (e.g., ...). Figure 15 The two-dimensional cross-sectional view of E is shown as arc CL in the flatter upper section, resulting in a finger protector body shorter (or lower) than the finger protector body 100f. With the arc C length remaining relatively constant, the arc C length is approximately the same as the arc CL. The abbreviation "arc CL" refers to an example arc C line of an SHWT glove with an arc C line of similar length to that of the SHWT glove being compared. Short finger protector bodies with reduced SHL (such as...) Figure 15 E, as shown in the two-dimensional extended finger sleeve shape, may cause all PIP and T-MCP joints (see...). Figure 2 A, Figure 8 B and Figure 8 C) Located above the SHL level. In this case, the top skirt wall may need to extend higher to protect the exposed PIP and / or T-MCP joints mentioned above.

[0372] The pivot point of a finger with a high SHL remains close to the height of the pivot point of these joints during pivoting movements of its PIP and T-MCP joints.

[0373] When the finger cot height SHL is relatively short ( Figure 15 E), the palm protection section of the SHWT glove will be positioned lower than the PIP and T-MCP joints. During the first PIP and T-MCP opening phase, as the PIP and T-MCP joints pivot outward to straighten the fingers and move the finger sleeves outward, they may not only bend the finger sleeves and palm protection section outward but also stretch / expand the palm protection section, including the virtual dome plate and the slightly wrapped top skirt wall (see [link]). Figure 8 B. Figure 8 C and Figure 15 E).

[0374] The distance between the short finger cot height (SHL) and the original finger cot height (SH) will be proportional to the corresponding palm protection stretch / expansion distance. Therefore, a glove body based on a short height SHL may introduce additional tensile force to expand the lower palm protection section.

[0375] SHWT gloves based on short finger height (SHL) may require extending their top skirt walls higher to protect exposed PIP and / or T-MCP joints, which could increase additional tensile forces.

[0376] Finger sleeves with a short finger sleeve height (SHL) may reduce the clamping force toward the inserted finger. Figure 8 The gap space 288 in the finger sleeve with a short finger sleeve height SHL shown in C may shift towards the lower part of the inserted thumb. The same applies to the other fingers. The downward shift of the gap space may reduce the contact surface between the finger sleeve wall and the inserted finger, resulting in a decrease in the finger sleeve clamping force and a decrease (or absence) in the fit around the middle of the finger. As previously stated, this is for Figure 8 The vertically inserted thumb shown in C can cause problems, potentially leading to finger slippage and affecting the clamping / gripping performance of the SHWT glove.

[0377] Furthermore, the short finger cuff height (SHL) creates a low and relatively flat virtual dome space beneath the palm, which may force the hand to use more additional bending force to center-grip objects with a height greater than the dome height (SHL), such as... Figure 8 The long object OL in D. Due to the additional SHWT glove structure deformation, the extra bending force may result in an unnatural hand grip experience.

[0378] If we further increase the finger sleeve height (SH) above the T-MCP joint level 271, since the finger sleeve height (SH) and bottom gripping radius (BRC) length are inversely proportional, it may reduce the bottom gripping radius (BRC) and ISD length, creating a smaller palm protection area. The reduced bottom gripping radius (BRC) and ISD may increase the likelihood that the SHWT glove needs to open to grip / grasp objects, thus increasing the probability that the hand may need to use additional opening force.

[0379] The small palm protection segment may cause the second MCP and CMC opening phase to occur earlier during hand opening because its initial MCP and CMC opening angles are smaller than the angle of the SHWT glove between the average height of the finger sleeve (SH) at the PIP joint and the height of the thumb T-MCP joint. This may lead to muscle fatigue because the four MCPs (excluding the T-MCP) and CMC joints use large additional tensile forces to expand the small palm protection segment earlier.

[0380] In SHWT gloves where the finger height (SH) falls within the range of the average height of the PIP joint and the height of the thumb T-MCP joint, the ability to pick up certain spherical object sizes may be limited by the arc C and arc B lengths during gripping between the center and finger sleeves. However, if the palm protection segment is too small, the second MCP and CMC opening phases may occur earlier, and the hand in the SHWT glove may reach the structural tensile / expansion limit of the palm protection segment before reaching the structural tensile / expansion limit based on arc C and arc B.

[0381] The small hand protection segment created by the height of the high finger sleeve (SH) reaches its structural tensile / expansion limit earlier and restricts all finger sleeves from opening further. This may prevent all finger sleeves (assuming all inserted fingers are straight) from reaching the equator of the target (spherical) object limited by the length of arc C.

[0382] Once we determine the finger height (SH), the inter-finger distance (ISD), and the bottom clamping radius (BRC) length, the size of the palm protection area can be determined. On one hand, the ratio of the average length of all bottom clamping radii (BRCs) to the finger height (SH) can range from 1:0.9 to 1:1.65. When defining the ratio of the bottom clamping radius (BRC) to the finger height (SH), both the bottom clamping radius (BRC) and the finger height (SH) can be measured when the SHWT glove is in a neutral position, for example, with the finger tips on a flat, horizontal surface and no user's hand inside the glove (which also means the finger body will not deform due to inserted fingers).

[0383] The hand protection section with a selected finger sleeve height (SH) and a selected bottom clamping radius (BRC) length allows the hand inserted into the SHWT glove to remain in a relaxed, open position before any opening or closing motion. The hand in the relaxed, open position within the SHWT glove can help reduce additional opening forces during opening motions by pre-setting the initial angles of the PIP, MCP, T-DIP, and CMC joints.

[0384] On the one hand, the relaxed opening angle of the PIP, T-MCP, and T-DIP joints can be between the maximum opening angle and the minimum closing angle, but is usually closer to the maximum opening angle. This may mean that the opening pivot movement is less than the closing pivot movement. This angle can accommodate the weaker opening ability of the finger muscles and the stronger closing ability of the finger muscles.

[0385] exist Figure 8 B and Figure 8 In C, all MCP and CMC joints (see...) Figure 2 A, Figure 8 B. Figure 8 C) Both are at their relaxed opening angle, which is close to their maximum opening angle, based on the structural tensile / expansion limits of the SHWT glove 100 using arcs C and B. The bottom clamping radius (BRC) length, determined by the finger sleeve height (SH) between the average height of the PIP joint and the height of the thumb T-MCP joint, allows the relaxed opening angle of the inserted MCP and CMC joints to be close to their maximum opening angle, thereby reducing additional tensile forces during opening movements.

[0386] At the end of the first PIP and T-MCP opening phase, all PIP, T-MCP, and T-DIP joints pivot outward to straighten all five fingers, which may stretch the SHWT glove 100 to near its structural stretch / expansion limits based on arcs C and B. Therefore, during the second MCP and CMC opening phase, the MCP and CMC joints move further outward from their relaxed opening angle by a relatively small amount to their maximum opening angle, reaching their structural stretch / expansion limits based on arcs C and B.

[0387] With all five fingers extended, the relatively small further pivoting movements of the MCP and CMC can reduce the additional stretching force on the hand that leads to hand fatigue.

[0388] Furthermore, the opening phase of the second MCP and CMC is delayed by the outward pivoting motion of all PIP, T-MCP and T-DIP joints and the five extended fingers.

[0389] Most large object grasping movements that require opening may only involve outward pivoting of one or more PIP, T-MCP, and T-DIP joints, which may only generate additional flexion forces to flex the finger sleeves, palm protection segments, and skirt walls outward, with little or no additional tensile force involved. This can avoid or delay the second MCP and CMC opening phase, which is dominated by additional tensile force and leads to hand fatigue.

[0390] The second MCP and CMC opening phases may only occur when attempting to grasp an object approaching the maximum size of a spherical object that can be gripped, which is determined by arcs C and B.

[0391] The selected palm protection zone size, determined by the finger sleeve height (SH) and bottom clamping radius (BRC) length and their ratio, is a factor in keeping the MCP and CMC joints relaxed at an angle close to their maximum opening angle. This can delay and reduce additional stretching forces during the opening action and reduce fatigue when the hand is open.

[0392] Selecting the appropriate palm protection segment size helps the second MCP and CMC opening phases reach the structural tensile / expansion limits based on arcs C and B, but avoids reaching these limits prematurely. The purpose of preventing the hand from reaching the palm protection segment's structural tensile / expansion limits before reaching the arc-based limits is to reduce additional opening forces exerted by the hand during the opening action in the SHWT glove. An appropriately selected palm protection segment size can also delay the application of additional tensile forces by the user and facilitates the grasping of the largest spherical objects, causing the SHWT glove to reach its palm protection segment's structural tensile / expansion limits later.

[0393] The selected palm protection segment based on finger sleeve height (SH) within the range between the average height of the PIP joint and the height of the thumb T-MCP joint can match the size of the human hand, such as... Figure 14 Top isometric view of C and its two related perspectives Figure 14 As shown in A and 14B, this palm protection section in the SHWT glove is similar to the close-fitting palm protection section of a regular five-finger glove, allowing the hand to open and close more naturally.

[0394] The outer cross-sectional perimeter of the palm protection section is defined as the perimeter of the finger protector 100f at its top edge, which is also the perimeter at the bottom of the top skirt connecting to the finger protector 100f. For the top skirt SW03 in the SHWT glove 100, since the skirt wall is nearly vertical and the lateral dimension of the top skirt is close to the perimeter of the top edge of the finger protector 100f, Figure 14 A, Figure 14 B and Figure 14C shows the top or bottom dimensions of the SHWT glove 100, which illustrates the close fit between the user's palm and the palm protection section of the SHWT glove.

[0395] With a relatively constant VD length, we can increase or decrease the aforementioned palm protection segment size by varying the finger sleeve height (SH) within the range between the average height of the PIP joint and the height of the thumb T-MCP joint, and / or by varying the ratio of the bottom clamping radius (BRC) to the finger sleeve height (SH) between 1:0.9 and 1:1.65. The resulting palm protection segment size may still be close to the user's palm size, for example... Figure 14 A, Figure 14 B and Figure 14 SHWT Glove 100 shown in C.

[0396] As stated above, when the palm protection section size of the SHWT glove matches the user's palm size, the lengths of arcs B and C under their respective upper limit rules become constraints on the extent to which the hand can open. This relates to the maximum spherical object that the SHWT glove can grasp with a center grip constrained by arc C and an interlocking grip by the fingers constrained by arc B.

[0397] Figure 16 A and Figure 16 B shows that the SHWT glove 133 has added protection to the central palm area and extends down along the inner wall of the finger sleeve to approximately the level of the PIP crease (approximately at the finger crease of a typical user—see Figure 5 D and Figure 8 The horizontal U / V-shaped groove 530 of the finger folds 282 in B). Figure 16 C shows a cross-sectional view 530C of a horizontal U / V-shaped groove. Figure 16 HUV arc C shown in C and similar HUV arc B (not shown in C) Figure 16 (As shown in C) A horizontal U / V-shaped groove 530 is embedded to replace the original arcs C and B, respectively.

[0398] Figure 16 A, Figure 16 B. Figure 16 C and Figure 16 D shows the horizontal U / V groove 530 in SHWT gloves 133 and SHWT gloves 136 that is relatively orthogonal to the HUV arc B and HUV arc C (or the original arc B and arc C) curves. Figure 16 C shows a cross-sectional view 530C of the horizontal U / V-shaped groove. (Reference) Figure 16 A, Figure 16 C and Figure 16D. The horizontal U / V-shaped groove 530 curves upward along the top skirt wall and extends to the edge of the top skirt, becoming a vertical U / V-shaped groove 531 (shown as a solid circle). The vertical U / V-shaped groove 531 can be located between the inter-arc bridging wing and the notched wing, and can be integrated with the inter-arc bridging wing and the notched wing.

[0399] Adding horizontal U / V grooves 530 orthogonal to the curves of arcs C and B can create adaptive HUV arcs B and C, allowing their lengths to be increased or decreased during hand opening and closing movements.

[0400] Figure 16 C illustrates the cross-section 530C of the horizontal U / V-shaped groove. When the hand is opened to the maximum open position of the SHWT glove hand, the horizontal U / V-shaped groove 530 can expand, which will increase the lengths of HUV arcs B and C. When the hand is closed to form a clenched grip, the horizontal U / V-shaped groove 530 can fold, which will reduce the lengths of HUV arcs B and C.

[0401] Because the horizontal U / V-shaped groove 530 can be folded more tightly, the lengths of HUV arcs B and C are reduced to a minimum when the hand is in a clenched position. These reduced minimum lengths of HUV arcs B and C can be achieved by following the principles outlined below. Figure 15 The average lengths of the projected arcs MR and MI, and the length limit rules for the gripping arc C are shown.

[0402] Taking HUV arc C as an example, we explain how the minimum reduction in HUV arc C length when folded tightly does not exceed the length of the tightly folded arc C. The same reasoning applies to the upper limit rule for HUV arc B length.

[0403] Assume that the HUV arc C can extend or decrease the arc C length by X. In a selected SHWT glove (e.g., SHWT glove 100 with the original arc C length), when the hand wearing the SHWT glove is in a gripped position and reaches the gripped arc C length, the arc C length will almost reach the limit of the gripped arc C length and will not push against the palm protection section. The arc C length with horizontal U / V grooves can further reduce the arc C to its minimum length, equal to "arc C - X".

[0404] The additional reduction in X length due to the tight folding effect of the horizontal U / V-shaped groove can be added back to the arc C, and still does not exceed the tight-grip arc C length limit. This new "arc C + X" length becomes the selected SHWT glove (e.g., Figure 16 C and Figure 16 The HUV arc length of the SHWT glove shown in D (133 or 136).

[0405] exist Figure 16In the SHWT glove 133 shown in C, the HUV arc C = arc C + X. When the hand reaches the length of the grip arc C in a gripping posture, the tightly folded horizontal U / V-shaped groove 530 will cause the length of the HUV arc C to decrease by X, that is, "arc C + X" - "X" equals the original arc C length.

[0406] The above discussion explains why the HUV arc C can be longer than the original arc C by X. When the horizontal U / V groove is tightly folded, the HUV arc C can be reduced to the length of the original arc C while still satisfying the tight-grip arc C length limit rule.

[0407] HUV arcs C and B can have an additional fold length than arcs C and B, and still satisfy the upper limit rules for arcs C and B.

[0408] like Figure 16 The HUV arc C of the SHWT glove 133 shown in Figure C is longer than the arc C of the SHWT glove 100 by X, and the VD length will also be increased proportionally to the HUV VD (not shown in the figure).

[0409] When we keep the palm protection section in SHWT glove 133 the same size as that in SHWT glove 100, the bottom gripping radius (BRC) can remain the same length, while the finger sleeve height (SH) can be increased proportionally. Figure 16 HUVSH as shown in C.

[0410] The HUV SH may be higher than the original finger sleeve height (SH). Adding a horizontal U / V groove near the PIP or T-MCP joint level can reduce the additional tensile force caused by the pivoting opening movements of the four MCP and CMC joints. A higher HUV SH may be higher than the average height of the PIP joint compared to the finger sleeve height (SH) in an SHWT glove without a horizontal U / V groove.

[0411] As mentioned above ( Figure 15 (As shown in the example in E), the distance between the lower finger sleeve height SHL and the finger sleeve height (SH) at the average height of the PIP joint will be proportional to the stretching / expansion distance of the palm protection segment caused by the opening pivoting motion of the PIP and T-MCP joints.

[0412] A similar principle applies to the MCP and CMC joints. Because the HUV SH is higher than the finger sleeve height (SH) in an SHWT glove without horizontal U / V grooves, and makes the finger sleeve height closer to the higher MCP and CMC joint levels, it can reduce the additional tensile forces caused by the opening pivoting motion of the MCP and CMC joints.

[0413] HUV SH can reduce the additional opening force caused by one or more PIP, T-MCP, and T-DIP joints because it is higher than the finger sleeve height (SH) of SHWT gloves without horizontal U / V grooves, especially when the size of the palm protection section determined by the bottom clamping radius (BRC) remains constant.

[0414] When the hand reaches the maximum open position of the SHWT glove, the maximum extension length of HUV arc C will be HUV arc C + X or equal to "arc C + 2X", and the maximum extension length of HUV arc B will be HUV arc B + X or equal to "arc B + 2X".

[0415] The extended lengths of HUV arcs B and C will proportionally increase the structural tensile / expansion limits of the hand protection segment, as well as the structural tensile / expansion limits based on arcs C and B (the maximum tensile / expansion limits of the SHWT glove structure may be equal to arc C + 2X and arc B + 2X).

[0416] This can reduce the additional bending and stretching forces during hand opening and closing movements, especially the additional stretching forces during the opening phases of the MCP and CMC.

[0417] The increased lengths of HUV arcs B and C during hand opening allow hands wearing SHWT gloves to open wider, thus increasing the maximum object size for center and finger-to-fingertip grip, which are previously limited by arcs C and B.

[0418] The reduction length of HUV arc C and HUV arc B from their initial length to their minimum length and the increase length from their maximum length do not necessarily have the same reduction and increase length X as in the illustrative example above. The reduction and increase lengths can differ depending on the design of the horizontal U / V groove structure.

[0419] The shape, size, and number of horizontal U / V grooves can be adjusted so that the width, height, thickness, or number of U / V grooves can be changed based on the wall material thickness of the SHWT glove and the amount of structural expansion to be achieved.

[0420] Horizontal U / V-shaped grooves can be implemented in different parts of the SHWT glove body. In one aspect, the horizontal U / V-shaped grooves can be implemented in the central palm protection section, which includes the arched section 108 and the central connecting area 103 (see...). Figure 1 B and Figure 1 D). In one respect, the horizontal U / V-shaped groove may be implemented along the inner wall of the finger sleeve. The horizontal U / V-shaped groove may be included in three- or four-finger SHWT gloves, and may be included in other aspects not explicitly shown herein.

[0421] Horizontal U / V grooves can be added along the inner wall of the finger sleeve at different percentages of finger sleeve height. On one hand, horizontal U / V grooves can be added at the finger sleeve height (SH) close to the average height of each finger joint pivoting movement (e.g., PIP and T-MCP) to reduce additional bending forces during hand opening and closing movements. Figure 16 The horizontal U / V groove 530 in the SHWT glove 133 shown in Figure A is implemented at a position close to and above the average crease height of the PIP joint, to illustrate that it can reduce the additional bending force of the PIP joint on the finger sleeve body during hand opening and closing movements.

[0422] We can also go along the inner wall of the finger sleeve 109C ( Figure 1 D) Add several additional small (or narrow) horizontal U / V grooves at the average level of the DIP joint to reduce the additional bending force of the DIP joint toward the finger sleeve body during hand opening and closing movements. Because Figure 1 The vertical height of the outer wall 104C of the finger sleeve in D is constant. The horizontal U / V-shaped groove added at the level of the DIP joint can extend arcs B and C to a certain range through the deformation of the finger sleeve body.

[0423] Adding horizontal U / V-shaped grooves may reduce the stiffness of the SHWT glove body. Therefore, we can increase the material thickness of the horizontal U / V-shaped grooves or increase the structural strength to prevent the SHWT glove body from collapsing in a standing position.

[0424] For the purpose of the SHWT glove's finger sleeve design, we can divide each finger sleeve into three parts along its longitudinal axis: the top finger sleeve opening 903, the middle finger sleeve section 902, and the bottom finger sleeve section 901, as shown below. Figure 9 A, Figure 9 B. Figure 9 C and Figure 9 The cross-sectional view of D is shown.

[0425] exist Figure 9 A, Figure 9 B. Figure 9 C and Figure 9 D (see also D) Figure 1 The top finger sleeve opening 903 can be integrated with the palm protection section, which is formed by the arch section 108, the central connecting area 103, and the top skirt. There is no clear boundary separating the top finger sleeve opening 903 from the middle finger sleeve section 902. We can consider the top finger sleeve opening 903 to include the top portion of the finger sleeve, whose inner wall curves towards the arch section 108 until the inner wall transitions to a straighter, vertical shape towards the bottom.

[0426] exist Figure 9 A, Figure 9 B. Figure 9 C and Figure 9 In D, the bottom finger sleeve section 901 is the bottom portion of the finger sleeve, including the end. The bottom finger sleeve section 901 accommodates the fingertip of the inserted finger up to at least the nail root (see...). Figure 8 B and Figure 8 (The position of the thumb 211 in C). The middle finger sleeve section 902 is the part of the finger sleeve between the top finger sleeve opening 903 and the bottom finger sleeve section 901. If the thumb is fully inserted into the finger sleeve, this part can cover the thumb DIP joint section.

[0427] The division of the three finger sleeve sections does not need to be precise, as the finger sleeves are a single piece from top to bottom. Furthermore, different variations in the SHWT glove finger sleeve design may cause the division of the three finger sleeve sections to deviate within a certain range of vertical height.

[0428] We will describe aspects of the SHWT glove's three-dimensional finger sleeve design. These include: 1) Design of the cross-sectional shape and dimensions of the finger sleeve from the middle finger sleeve area centered on the T-DIP joint down to the end of the finger sleeve; the finger sleeves of SHWT 100 and SHWT230 were used as references for finger sleeve clamping force analysis and structural shape design. The following description will cover the design of the three-dimensional shape of the SHWT finger sleeve. These shapes are divided into convex ring and hybrid ring shapes, which have their own width (OW) to height (OH) ratios at different percentages of the finger sleeve height (SH).

[0429] 2) Design of the longitudinal cross-sectional shape of the finger sleeve from the middle finger sleeve section downwards to the end of the finger sleeve (see...) Figure 8 A, Figure 8 B. Figure 8 C and Figure 9 A, Figure 9 B. Figure 9 C and Figure 9 D).

[0430] 3) Focus on the front shape design of the finger sleeve in the bottom finger sleeve section (see...) Figure 2 A, Figure 5 A and Figure 12 A SHWT Glove 100 (front view finger cot). The front view shape is an isometric view along the clamping radius (RC) direction, such as... Figure 12 As shown in A, II, and III.

[0431] The opening at the top of the finger sleeve can be integrated with the palm protection segment forming the virtual dome plate, the upper section of which curves along arc C following the curvature of the parallel-inserted index and / or middle fingers (see...). Figure 8 B and Figure 8 C). Two-dimensional view reference of the shape of the opening of the top finger sleeve. Figure 9 E and Figure 9 F. The design of the top finger sleeve opening covers the palm protection section.

[0432] We will use Figure 2 The cross-section shown in Figure C illustrates the design of the finger sleeve cross-section at the cut plane. The finger sleeve section surrounding this plane is the middle finger sleeve section, which at least surrounds the T-DIP joint portion of the single inserted thumb.

[0433] refer to Figure 8 B and Figure 8 C, the T-DIP joint of the thumb may be higher than the other DIP joints where the fingers are fully inserted, therefore we choose Figure 2 C or Figure 10 The horizontal T-DIP-H in the middle of the T-DIP joint section shown in A serves as a cross-sectional cutting plane, providing a better representation of the finger sleeve size, shape, finger sleeve deformation, and clamping force on the inserted finger.

[0434] Above the horizontal cutting plane in the middle of this T-DIP joint segment, the cross-section of the finger sleeve may deviate and transition towards the shape of the top finger sleeve opening, which may increase the finger sleeve size. Below this cutting plane, the cross-section of the finger sleeve may deviate and transition towards the bottom finger sleeve segment, which has... Figure 9 A, Figure 9 B. Figure 9 C Figure 9 D、 Figure 21 D and Figure 21 The different shapes are listed in E.

[0435] We will use along Figure 8 The design of the longitudinal cross-section of the finger sleeve is illustrated by the longitudinal cross-section at the cutting plane of the arc C shown in Figure A. Figure 8 A shows that the central cutting plane of the finger sleeve along arc C has a 120-degree interplanar angle due to the rotational symmetry of the SHWT glove 100. This 120-degree angle is also the angle between adjacent bottom clamping radii (BRC) on the cross-section of the SHWT glove. Figure 8 B shows a side view of the longitudinal cross-sectional cut shape relative to the inserted index finger. Figure 8 C shows their side views relative to the inserted thumb.

[0436] Previously, gloves on the market had each finger cot designed to accommodate only one finger. When a finger was inserted, the cross-sectional shape of the finger cot was nearly circular. When a person's finger was inserted into the finger cot, which was made of elastic / soft material and matched to the circumference of the finger, there was almost no gap space between the finger and the finger cot. The finger cot size closely matched the finger size and produced a tight wrapping effect, and it was assumed that one end of the finger cot was closed, which could result in no air entering or exiting.

[0437] These finger cots can make inserting and removing fingers difficult or even impossible. This is why a second hand is needed to help put on and take off the gloves from the wearing hand. This is especially problematic when large fingers or multiple fingers need to be inserted into relatively tight finger cots. Due to the wrapping effect (due to maximum contact friction between the finger cots) and the airtight effect (due to the lack of airflow), the fingers may become trapped inside the rounded finger cots. In this case, a second hand is needed to put on and take off the gloves from the wearing hand.

[0438] SHWT gloves feature finger sleeves that allow for the insertion of one or more fingers per sleeve, while each finger sleeve also provides sufficient clamping force to securely hold a single inserted finger (such as a parallel thumb, index, or middle finger, or a non-parallel ring finger) inside and prevent them from slipping out.

[0439] In SHWT based on three-finger sleeves, it is also possible to insert three fingers into a single finger sleeve, with the middle finger, ring finger, and part of the little finger inserted into a single finger sleeve in a non-parallel manner (note: in this case, the little finger may not be fully inserted into the finger sleeve because it is shorter than the ring finger).

[0440] SHWT gloves can be made with finger sleeves of large cross-sectional circumference to accommodate one, two, or more fingers in a given sleeve. Properly designing the shape and size of the finger sleeves helps prevent fingers from becoming trapped inside due to tight wrapping and airtightness.

[0441] From the middle finger sleeve section to the end of the finger sleeve, the cross-sectional perimeter of each finger sleeve can be greater than 210 times the cross-sectional perimeter of a finger inserted at the same percentage of finger sleeve height. Figure 2 D (in the middle).

[0442] like Figure 2 As shown in D, the circumference 210 of the inserted finger does not include the space surrounding the interdigital space 218b. Figure 2 D) The finger circumference segments are replaced by the finger sleeve wall length (cross-section) at the finger gap 218b, plus the cross-sectional circumference segment at the contact area between the finger and the finger sleeve, and the finger side length at the two finger sleeve side gaps 218a.

[0443] In a three-finger SHWT glove, the minimum perimeter of the finger sleeve cross-section from the middle finger sleeve section to the end of the finger sleeve can be greater than the perimeter 210 of the index and middle finger combination or the middle and ring finger combination. The perimeter 210 of the index and middle finger combination or the middle and ring finger combination is chosen as a design reference because it represents most two-finger insertion combinations in a three-finger SHWT glove. Furthermore, the perimeter 210 of the index and middle finger combination or the middle and ring finger combination is greater than the perimeter 210 of other two finger combinations in the hand (e.g., ring and little finger). Depending on different hand anatomy, the perimeter 210 of the index and middle finger combination may be greater than that of the middle and ring finger combination in some hands. The average perimeter 210 of the index and middle finger combination versus the middle and ring finger combination can be used as a design reference. For SHWT gloves based on four-finger cots, the circumference of 210 for the ring and little finger combination can be used as a design reference, as this finger combination is probably the most common in SHWT gloves based on four-finger cots.

[0444] When three fingers need to be inserted into one finger sleeve of a three-finger SHWT glove, one way to wear the SHWT glove is to place the middle, ring, and little fingers in one finger sleeve. The little finger is shorter than the other two fingers and therefore may not be fully inserted into the bottom of the finger sleeve. The gradually increasing finger sleeve circumference from the middle finger sleeve section to the top finger sleeve opening, due to the curvature of the inner wall of the finger sleeve towards the arch section 108 (and the central connecting area 103), creates more space for the insertion of three fingers in the above situation. The elastic, stretchable finger sleeve material allows for additional space to accommodate the insertion of three fingers.

[0445] In cases where three fingers are inserted and there is some effect of the finger sleeve covering them, as described below, there are several methods to remove the fingers from the finger sleeve without the aid of a second hand.

[0446] When using finger sleeves with a circumference larger than the inserted finger, the finger may not stay securely in place and could accidentally slip out. Therefore, we can use a chosen finger sleeve shape design to complement a larger finger sleeve size. A larger finger sleeve size combined with a chosen shape design increases the gripping force of the finger sleeve on the inserted finger, making it less likely for the finger to slip out accidentally, while also allowing for easy removal of the finger sleeve when needed without the assistance of a second hand.

[0447] The finger sleeve shape design also helps prevent the SHWT glove from collapsing during finger insertion.

[0448] As mentioned above, Figure 2 The cross-section of the finger cot at the height of the transverse cutting plane T-DIP-H in C will be used to illustrate the design. Figure 2D is an isometric view of the cross-section of the finger sleeve as seen from the bottom of the glove with finger insertion assembly at the transverse cutting plane.

[0449] For the purpose of finger sleeve design, we approximate the cross-sectional shape of a human finger as a near-circular ellipse, especially when the finger skin has some deformation; this is close enough. For illustration, Figure 11 C shows the elliptical cross-section of the middle finger 213C and its elliptical height 213C OH.

[0450] To estimate the cross-sectional shape of a finger, taking the T-DIP joint cross-section of the thumb as an example, one approach is to sample the shape of a single cross-section cut. However, since the T-DIP joint is not straight, its uneven surface contains ridges or DIP protrusions 800 (see...). Figure 8 B and Figure 8 C), we can follow Figure 2 C and Figure 10 The T-DIP segment height shown in the square segment of A is sampled uniformly from several transverse cut shapes, and the average T-DIP shape 207 is calculated. The cross-sectional shapes of the remaining fingers can be obtained using the method described above to obtain a more effective shape and size reference.

[0451] Figure 10 Some examples of finger sleeve cross-sectional shapes are shown. Figure 10 All finger sleeves have a cross-sectional width OW to height OH ratio > 2:1. The finger sleeve cross-section is cut horizontally downwards from the T-DIP-H to the end of the finger sleeve (e.g., Figure 2 C and Figure 10 As shown in A, the ratio of OW to OH can be > 2:1, and this ratio gradually increases toward 0% of the finger sleeve height (SH) (see Figure A). Figure 21 D and Figure 21 E). The cross-section of the finger sleeve can be designed to be symmetrical along the clamping radius (RC). Figure 10 All variations shown are linearly symmetrical. Linear symmetry in the cross-section of the finger sleeves is not mandatory, but it improves universal fit for left- or right-handed wear. SHWT gloves with asymmetrical finger sleeves may create different sensations for left- and right-handed wear, but using soft or elastic glove materials, they can still provide near-universal fit. (Compare...) Figure 13 SHWT Gloves 100 with linearly symmetrical finger sleeves in C and Figure 13 The SHWT glove with a non-linearly symmetrical finger sleeve is shown in D.

[0452] Considering the need to accommodate a single finger insertion, the cross-sectional height (OH) of the finger sleeve is... Figure 10 B and Figure 10(As shown in C) can be smaller than the height of the cross-sectional ellipse of a single parallel-inserted thumb, such as Figure 2 As shown in the top finger sleeve in D, or using Figure 2 The average shape of the T-DIP in C is 207, which is used as a reference. The oval height of the thumb is a design reference because in SHWT gloves based on three-finger sleeves, the thumb typically occupies one finger sleeve.

[0453] For SHWT gloves based on three-finger cots, the index finger is typically inserted into a single finger cot parallel to the middle finger. However, the thumb and index finger can each occupy a separate finger cot. If we need to design a single finger cot for a single index finger, the cross-sectional height (OH) of the finger cot can be reduced to be the same as or smaller than the elliptical height of the parallel-inserted index finger.

[0454] For SHWT based on four-finger cots, for example Figure 13 A and Figure 13 In SHWT Glove 250 of B, considering the case of a single index finger inserted into a single finger sleeve, the cross-sectional height (OH) of the finger sleeve can be the same as or smaller than the elliptical height of a single parallel inserted index finger.

[0455] like Figure 2 As shown in the top finger sleeve of the SHWT glove 100 in D, the cross-sectional height (OH) of the finger sleeve can be limited to an elliptical height no longer than the thumb, allowing the inserted thumb to deform and expand the sides of the finger sleeve wall along the height (OH) direction. The deformed finger sleeve wall increases the static friction with the thumb contact surface, generating a clamping force that holds the thumb within the finger sleeve. This clamping force likely occurs primarily in the middle (cross-section) of the finger sleeve along the height (OH) direction, as a single inserted finger is mainly located around the middle of the finger sleeve, such as... Figure 2 D is shown as thumb 211C.

[0456] For single-finger insertion, the finger sleeve is relatively large compared to the finger itself, and most of the clamping force occurs in the middle of the inner and outer walls of the finger sleeve, so a tight fit that traps the finger within the sleeve is not a problem. If more clamping force is needed, the cross-sectional height (OH) of the finger sleeve can be further reduced. When a single finger is inserted parallel to the finger sleeve and held in a relaxed, open position, the T-DIP or I-DIP joint protrusion on each finger is 800° (e.g., ...). Figure 8 B and Figure 8 (As shown in C) slightly bent. The front and back sides of the bent finger may abut against and keep the relatively straight inner and outer walls of the finger sleeve (as shown in C) in the middle and bottom finger sleeve sections. Figure 1 The inner wall 109C and outer wall 104C shown in D are deformed. This generates additional clamping force to keep a single finger inside the finger sleeve.

[0457] Compared to the relatively straight lower and middle finger sleeve body, the slightly curved DIP joint shape of the other fingers may generate additional clamping force, similar to the case of T-DIP or I-DIP joints.

[0458] When multiple fingers are inserted into a single finger cot, a greater clamping force may be generated compared to single finger insertion, because the circumference of multiple fingers is 210 (in...). Figure 2 (D) is larger than the circumference of a single finger. They can easily make the inner wall of the finger sleeve 109C and the outer wall 104C (as shown in the image). Figure 1 (As shown in D) Deformation to generate sufficient clamping force. Figure 2 D shows the insertion of multiple fingers into the lower left and lower right finger sleeves and how the cross-section of the finger sleeves deforms.

[0459] Figure 11 C shows, as an example, the middle finger 213C inside the finger cot 231C of the SHWT glove 230. The finger cot 231C (with...) Figure 10 The finger sleeves (similar to those in the SHWT glove 230 shown in B) can be considered to be divided into two symmetrical halves along the height (OH) direction. Each half of the finger sleeve has a single angle on its side. When multiple fingers are inserted into the finger sleeve in parallel, the fingers occupying each side of the finger sleeve may deform the corresponding side angle.

[0460] Figure 11 D illustrates the finger sleeve deformation in more detail using the finger sleeve 101C of the SHWT glove 100 as an example. When both the index finger 212C and the middle finger 213C are inserted parallel to each other into a single finger sleeve, Figure 11 In D, the middle finger 213C deforms the right half of the finger sleeve wall and is clamped by the right corner. Similarly, the index finger 212C deforms the left half of the finger sleeve wall and is clamped by the left single corner (see also...). Figure 2 D).

[0461] When the side corners of the finger sleeve deform, additional deformation may occur in the middle of the finger sleeve. To better illustrate this, we will... Figure 11 In Figure C, ARC IN is defined as the arc in the middle of the inner wall of the finger sleeve (2D view), and ARC EXT is defined as the arc in the middle of the outer wall of the finger sleeve. These two arcs connect the two side corners. Figure 11 D illustrates the deformation at ARC IN and ARC EXT in the finger sleeve 101C of the SHWT glove 100. When the index finger 212C and middle finger 213C are inserted parallel to each other, ARC IN and ARC EXT will be stretched into a flatter shape, and the interfinal gap 218b may decrease. The incremental space between the two dashed lines represents the degree of deformation at ARC IN and ARC EXT relative to the original finger sleeve shape.

[0462] The deformation of the finger sleeves at the two side corners and the connecting arc of the middle side corner can provide a better fit for the inserted fingers, making the fingers in SHWT feel natural when grasping or holding objects, and closer to the feeling of grasping objects with bare hands.

[0463] Unlike single-finger insertion, which focuses on securing and holding the finger firmly within the finger sleeve, multi-finger insertion focuses on mitigating excessive clamping force, which makes it difficult to pull the finger out of the sleeve during self-disengagement. Figure 11 C or Figure 11 The finger sleeve side angle shape design shown in D plays a role in improving the finger sleeve clamping force.

[0464] We can adjust two aspects of the side angle shape to improve the gripping force of the finger sleeve. They are... Figure 11 The side angle approximates the angle NTA shown in C, and is derived from... Figure 11 C and Figure 11 The side angle sharpness, determined by the side angle clamping arm length NCA1 (or NCA2) in D and the effective arc size at the end of the side angle, will be explained below.

[0465] Note here that we use the effective arc size because the end of the side angle does not need to be a perfect arc, but an approximate arc, for example... Figure 22 The convex segments “b”, “c”, and “d” listed in A.

[0466] like Figure 11 As shown in C, NTA represents the approximate angle of the finger sleeve's side angle. Since the side angle is formed by a rounded arc rather than entirely by straight lines, NTA is merely an approximation of the angle. Adjusting NTA will change the width (OW) to height (OH) ratio of the finger sleeve's cross-section. Generally, a small NTA will produce a narrow side angle with a high width (OW) to height (OH) ratio, which may help increase the clamping force towards the inserted finger, while a large NTA will produce a wide side angle with a low width (OW) to height (OH) ratio, which may reduce the clamping force, especially for a single inserted finger.

[0467] like Figure 11 As shown in Figure C, the ARC 231 of the finger sleeve cross-section 231C of the SHWT glove 230 is arc-shaped and is at the end of the side corner. The radius of the effective arc at the end of the side corner can be smaller than the arc radius of the adjacent inserted finger, especially from the middle segment of the finger towards the fingertip. Limiting the radius of the arc at the end of the side corner will leave a gap between the inserted finger and the end of the side corner, as shown in Figure C. Figure 2 D and Figure 11 The finger sleeve side gap 218a is shown in C. Figure 11C illustrates this situation, with a finger sleeve side gap 218a between the inserted middle finger 213C and the lateral corner end arc ARC 231 on the right side of the finger sleeve. This gap helps reduce the tight wrapping and airtight effect of the finger sleeve that could trap the finger inside. It also serves as additional cushioning space, allowing for the insertion of larger fingers.

[0468] Figure 11 C shows that the finger sleeve 231C of the SHWT glove 230 has a side angle, the side angle having a side angle angle NTA, a side angle arm length NCA1, and a side angle end arc ARC 231 that follows the side angle end arc radius restriction rule.

[0469] Figure 11 D shows that the finger sleeve 101C of the SHWT glove 100 has a side angle, the side angle has a side angle clamping arm length NCA1 and a side angle end arc ARC 101 that follows the side angle end arc radius limitation rules.

[0470] if Figure 11 The SHWT gloves 230 with ARC 231 and NCA1 in C have side corners and Figure 11 The SHWT gloves 100 with ARC101 and NCA1 in D have excessive clamping force on the side angles for thicker or more fingers inserted. We can make the side angles sharper or extend them. Figure 11 C and Figure 11 D shows the original arcs ARC 231 and ARC 101 extended into arc ARC 2 with a smaller radius and a longer clamping arm NCA2. This sharper flank angle produces a less clamping force than the original blunt flank angle. This is because, as Figure 11 As shown in C, the sharper side angle with ARC 2 has a larger perimeter and extends the finger sleeve side gap 218a by an additional 218ext (as shown in Figure C). Figure 11 (as shown in C).

[0471] With clamping arms having a shorter side angle ( Figure 11 C and Figure 11 Compared to the obtuse lateral angle of NCA1 in D, the clamping arm with a longer lateral angle ( Figure 11 C and Figure 11 The sharp lateral angle of NCA2 in D allows for smaller deformation variations and thus smaller variations in clamping force when inserting fingers of different sizes (or thicknesses) into the finger sleeve. Therefore, the sharp lateral angle has better tolerance for different sized fingers and maintains a relatively constant clamping force than the obtuse lateral angle.

[0472] When multiple fingers are inserted into a single finger sleeve Figure 2 D and Figure 11The finger gap 218b shown in D allows airflow and helps reduce the contact surface and friction between the finger and the finger sleeve wall. Furthermore, multiple fingers can trigger reciprocating motions between each other, making it easier to remove the fingers from the finger sleeve. Figure 12 This is illustrated in A using index finger 212 and middle finger 213. This reciprocating motion of multiple finger insertions allows the fingers to break free from the finger sleeves, a unique feature not found in traditional gloves, which focus on finger sleeve designs based on single finger insertion.

[0473] For SHWT gloves typically with three fingers inserted into one finger cot—for example, the middle, ring, and little fingers—and the thumb and index finger each occupying the other two cots, the reciprocating motion between the middle, ring, and little fingers helps to free them from the cots. Furthermore, the thumb and index finger can be easily pulled out of their respective cots. The pulled-out thumb and index finger can then help push against the palm-protected section to further assist in pulling the other three fingers out of their cots. Therefore, even with three fingers inserted into one cot, it is possible to remove the SHWT glove without problems without the assistance of a second hand or other tools. Single-handed removal can be beneficial when the second hand is performing a task, is dirty, or otherwise unavailable.

[0474] like Figure 2 As shown in D, the cross-sections of the thumb 211C (top finger sleeve), the index finger 212C, and the middle finger 213C (lower left finger sleeve) can be inserted parallel to the finger sleeves of the SHWT glove 100, but the cross-sections of the ring finger 214C and the little finger 215C (lower right finger sleeve) cannot. Figure 2 A shows the same situation in a perspective view. Due to the anatomy of the hand, in a rotationally symmetrical SHWT glove, when the ring and little fingers are inserted into a finger sleeve, they cannot be inserted parallel to each other, but rather at an angle of approximately 30 to 90 degrees, and this angle may change dynamically during hand movements.

[0475] Because the circumference of the ring and little fingers is smaller than that of the thumb, index, and middle fingers, there may be concerns that finger sleeves may not provide enough clamping force to keep the ring and little fingers inside. However, since the ring and little fingers are usually... Figure 2 As shown in the lower right finger cot D, the finger cot is inserted non-parallel; therefore, angled finger insertion may cause greater deformation of the cot wall than parallel finger insertion. This additional deformation may generate a greater clamping force to compensate for the smaller clamping force due to the smaller finger circumference.

[0476] In some cases, the little finger may remain outside the finger sleeve, while the ring finger is inserted non-parallel into the finger sleeve. Although the circumference of the ring finger is smaller than that of the thumb inserted parallel to it, an angled insertion of the ring finger can produce a similar clamping force to the finger sleeve.

[0477] The expansion / deformation distance of the finger sleeve from a non-parallel insertion of the ring finger may be greater than the elliptical height of the ring finger and closer to the elliptical width. This is one reason why the finger sleeve may have sufficient clamping force when inserted into the ring finger. Furthermore, when the ring finger itself inserts into the finger sleeve, it may naturally bend, with its R-DIP and R-PIP joints bending to create an angled insertion. This angled insertion of the ring finger may allow the finger sleeve to generate some clamping force.

[0478] Figure 10 This document lists some variations of the SHWT glove cross-sectional shape design when adjustments are needed for different material properties, material thicknesses, and applications.

[0479] Figure 10 B shows a cross-section of the finger sleeve of the SHWT glove 230. Figure 11 D shows the same finger cot in more detail. For this type of finger cot design, when the finger cots are squeezed together to hold a small object in the center, it may form a shape like... Figure 8 The large center gap 180 shown in the bottom diagram of Figure E. When the center gap 180 is large, the hand may need to apply additional force (such as...). Figure 8 (As indicated by the arrow in D) to bend / squeeze the finger sleeve wall in the area surrounding the center gap 180 in order to reach small objects in the center, especially when the inner wall of the finger sleeve is made of a thick material.

[0480] The additional finger sleeve bending force used to deform the finger sleeve wall to close the central gap 180° and reach the central small object increases the original additional bending force required to hold the object and increases the total additional closing force required by the hand.

[0481] Therefore, the finger sleeve shape of the SHWT 230 glove may be better suited to thinner and more flexible materials that can more easily deform along the fingers, making it easier to grip small objects in the center, such as... Figure 8 As shown in E, it does not cause the fingers to use too much additional bending / compression force. When the hand grasps a small object in the center, such as... Figure 8 As shown in E, a thumb inserted parallel to a single finger sleeve may exert additional squeezing force against the inner wall of the finger sleeve in order to reach an object smaller than 180 degrees from the center gap.

[0482] refer to Figure 10 A and Figure 10 B. We define 100M1 as the midpoint on the inner wall of the finger sleeve and 100M2 as the midpoint on the outer wall of the finger sleeve. In this example, 100M1 is the endpoint of the finger sleeve cross-sectional height (OH) on the inner wall of the finger sleeve, and 100M2 is the endpoint of the finger sleeve cross-sectional height (OH) on the outer wall.

[0483] Figure 10 A shows that the cross-section of the SHWT glove 100 is triangular, with a small arc radius ARC IN centered at the midpoint 100M1 on the inner wall of the finger sleeve, as shown. Figure 10 As shown in the dashed elliptical circle in A, to reduce Figure 8 The center gap of 180, as shown in E, improves the performance of gripping small objects. Its ARC IN radius can be aligned with the forward arc of the thumb (see...). Figure 2 The forward arc of the thumb (211C) or index finger in D is the same as or similar to that of the index finger. The thumb or index finger can be a design reference because in common uses of SHWT gloves, the thumb or index finger may each occupy a finger sleeve. In the cross-section of a non-triangular finger sleeve, the ARC IN length can be defined as equal to OW / 3 length, which may be close to the width of an elliptical thumb or index finger.

[0484] Furthermore, the small radius ARC IN of the finger sleeves of the SHWT Glove 100 is formed by two straight edges spaced 120 degrees apart. For example... Figure 1 C or Figure 8 As shown in E, the straight edges facing each other on adjacent finger sleeves are parallel. These parallel straight edges are also part of the inverted U-shaped channel 106. In the case of the SHWT glove 100, the outer width 105a of the inverted U-shaped channel 106 is the same as the inner width 105b of the inverted U-shaped channel 106, as shown in E. Figure 1 As shown in C.

[0485] refer to Figure 8 E. Compared to the cross-sectional shape of the finger sleeves of SHWT glove 230, the cross-sectional shape of SHWT glove 100 results in parallel inverted U-shaped channels 106 that improve inter-finger gripping performance. Furthermore, when the finger sleeves of SHWT glove 100 are squeezed together, compared to the center gap 180 shown in the bottom diagram of SHWT glove 230, Figure 8 The center gap 180 shown in the top diagram is smaller. Therefore, the finger sleeve design of the SHWT glove 100 improves center grip performance, especially for small objects.

[0486] The triangular cross-section of the finger cots reinforces the vertical support of the SHWT glove 100, similar to right-angled metal strips (or angle strips with L-shaped cross-sections) used to reinforce building structures. This helps reduce the likelihood of the finger cots collapsing when multiple fingers are inserted into a standing SHWT glove.

[0487] For SHWT gloves 100 and SHWT gloves 230, the cross-section of the finger sleeves can transition to a similar elliptical shape with a height-to-width (OW) to height (OH) ratio greater than 2:1 in the bottom finger sleeve section. Therefore, as... Figure 12 B and Figure 12As shown in Figure C, when the finger cots are squeezed together to pick up small objects, a central gap of 180° exists near the ends of the finger cots. When the hand uses the fingertips to pick up small objects, the fingers naturally rotate and move at the fingertips to reduce the gap between the fingertips. Figure 12 D and Figure 12 As shown in E, the SHWT glove finger sleeves follow the natural rotation and movement of the fingers and reduce the center gap 180 near the end of the finger sleeves, which allows the hand in the SHWT glove to pick up small objects, such as small fries 301.

[0488] Traditional gloves on the market are primarily designed to fit a single finger inserted into a single finger sleeve. To optimize performance when picking up small objects, the fingertips of these gloves may be designed to closely follow the shape of the inserted finger, which can result in a tight wrapping effect.

[0489] Figure 10 C shows a basis Figure 10 The alternative cross-sectional shape for the finger sleeve design of SHWT Glove 100 in A. Figure 10 The cross-section in C has two lateral angles on each side of the finger sleeve (as shown in the unfolded window on the left), which are sharper than those of the SHWT glove 100, to adjust the clamping force on the sides of the finger sleeve. Furthermore, the sharper lateral angles increase the vertical support on the sides of the finger sleeve. It mimics a right-angled bar structure to enhance the vertical rigidity of the finger sleeve body, preventing the finger sleeve from collapsing during finger insertion.

[0490] also, Figure 10 The cross-section of the finger sleeve in C can be modified to have a flat shape 500C on the outer wall of the finger sleeve, to replace Figure 10 The original outward-curving portion of finger sleeve A. This is an alternative design that can increase the clamping force of a single parallel inserted finger. The outer wall of the finger sleeve can be inwardly curved, which can provide better clamping force for a single inserted finger.

[0491] Another way to improve the clamping performance of finger sleeves is to embed vertical U / V-shaped grooves along the outer wall of the finger sleeve. Figure 10 D and Figure 10 E illustrates a vertical U / V-shaped groove (531C in cross-sectional view) added to the outer wall of the finger sleeve to make the finger sleeve more adaptable to various numbers of fingers and different finger sizes. When the vertical U / V-shaped groove has sharp angles, it is more like a V-shape than a U-shape. Both "U"-shaped and "V"-shaped vertical U / V-shaped grooves are acceptable.

[0492] Figure 10 D shows the finger cots of the SHWT glove 130 with vertical U / V-shaped grooves (531C in cross-sectional view). Figure 13 E and Figure 13F illustrates an SHWT glove 130 based on the design of the SHWT glove 100, in which all three finger sleeves are embedded in vertical U / V-shaped grooves 531 extending vertically along the outer wall of the finger sleeves, and may disappear near the ends of the finger sleeves, as shown. Figure 13 The expanded window of F is shown.

[0493] The finger sleeve with a vertical U / V-shaped groove has an adaptive cross-sectional circumference to accommodate different finger circumferences. Figure 2 D). Adaptive finger sleeve circumference may be useful for inserting three fingers (e.g., middle, ring, and little fingers into one finger sleeve) or two unusually large / thick fingers into one finger sleeve.

[0494] When vertical U / V grooves are implemented in SHWT gloves based on four-finger cots, it can help improve the clamping force of the finger cots for single and two-finger insertion.

[0495] On the one hand, finger cots without vertical U / V-shaped grooves can be used to insert two fingers with a small circumference of 210 ( Figure 2 D) Slender fingers. Finger sleeves with a fixed cross-sectional circumference, for example... Figure 10 A and Figure 10 Those shown in B can primarily use side angle design and a width (OW) to height (OH) ratio greater than 2:1, for example in SHWT gloves based on three-finger cots, to control clamping force.

[0496] When two large / thick fingers or three fingers are inserted into the same finger sleeve, the cross-sectional circumference of the finger sleeve increases only to a limited extent due to the elasticity of the material. Therefore, two large / thick fingers (or three fingers) may fill more than necessary. Figure 2 As shown in Figure D, the finger sleeve side gap 218a and interfinite finger gap 218b are drastically reduced. In this case, the contact surface between the inserted finger and the finger sleeve wall increases. The large clamping force and tight wrapping effect may dominate, making it difficult for the hand to remove the SHWT glove on its own.

[0497] When a large / thick finger is inserted... Figure 10 D and Figure 10 When the finger sleeve shown in E has a vertical U / V-shaped groove, the vertical U / V-shaped groove stretches wider and increases the total circumference of the finger sleeve. This reduces... Figure 2The finger sleeve side gaps 218a and interfinite gaps 218b shown in D are less reduced than those of finger sleeves without vertical U / V grooves. Due to the wavy structure with multiple peaks and valleys, the vertical U / V grooves themselves also create additional gap space between the inserted finger and the outer wall of the finger sleeve. The vertical U / V grooves help reduce the clamping force of the finger sleeve to an appropriate range. This reduces the tight wrapping effect of the finger sleeve and helps the hand to be removed from the SHWT glove on its own. When inserting a single finger or a slender finger, the peaks on the vertical U / V grooves, which slope towards the finger, also help generate additional clamping force to securely hold the finger.

[0498] In summary, finger cots with vertical U / V-shaped grooves (such as those in SHWT Gloves 130) Figure 10 D、 Figure 13 E and Figure 13 F) It can have better tolerance when the number or size of the inserted fingers varies, because the adaptive cross-sectional perimeter expands and contracts with the inserted fingers, and the resulting clamping force has a smaller deviation range.

[0499] Finger sleeves with vertical U / V grooves (such as those in SHWT Glove 130) can have a larger total extended perimeter than finger sleeves in SHWT Glove 100 without vertical U / V grooves. If the vertical U / V grooves are deep, the total extended perimeter can become too large, which may result in reduced finger sleeve clamping force, especially for a single inserted thumb. We can compensate for the reduced clamping force by reducing the cross-sectional length of the finger sleeve segment that is not part of the vertical U / V groove. The cross-section of the finger sleeve containing the vertical U / V groove can be used to calculate its initial perimeter 006 (before U / V extension) using the initial chord length of the U / V, as shown below. Figure 10 As shown in D.

[0500] SHWT finger sleeves with expandable structures (such as vertical U / V-shaped grooves embedded in the outer wall of the finger sleeve) can have a smaller width (OW) to height (OH) ratio than SHWT finger sleeves without expandable structures, while still achieving similar clamping performance.

[0501] To explain this, if we make the expanded perimeter of the finger sleeve cross-section with the vertical U / V groove the same as the perimeter of the finger sleeve cross-section without the vertical U / V groove, then the initial perimeter of the finger sleeve cross-section with the vertical U / V groove before the vertical U / V groove expands is 006 ( Figure 10 (As shown by the dashed line in D) will be smaller than the perimeter of the cross-section of a finger sleeve without a vertical U / V-shaped groove.

[0502] If we keep the height (OH) of the cross-section of the finger sleeve with the vertical U / V-shaped groove constant, we can reduce Figure 11 C or Figure 11 The NCA1 or NCA2 arm in D is used to reduce the width (OW) of the finger sleeve cross-section by leaving a smaller finger sleeve side gap 218a. The resulting width (OW) to height (OH) ratio will be smaller than that of the SHWT finger sleeve without the vertical U / V groove.

[0503] although Figure 10 D and Figure 10 E shows that the width (OW) to height (OH) ratio of the finger sleeve with vertical U / V-shaped grooves is > 2:1, because they are respectively directed to SHWT glove 100 ( Figure 10 A) and SHWT gloves 230 ( Figure 10 B) The result of adding vertical U / V shaped grooves, but Figure 10 D and Figure 10 The ratio of width (OW) to height (OH) in E can be reduced to less than 2:1 from the T-DIP joint level or the middle finger sleeve area to the end of the finger sleeve (provided that a vertical U / V groove is implemented).

[0504] The vertical U / V groove can create additional gap space between the inserted finger and the finger sleeve wall with the vertical U / V groove applied, which can help compensate for the two smaller finger sleeve side gaps 218a and avoid the finger sleeve tightly wrapping effect.

[0505] In addition, finger sleeves with vertical U / V-shaped grooves can reduce the finger sleeve width (OW). The reduced finger sleeve width (OW) can also improve the fit of the finger sleeve when inserted.

[0506] Figure 13 E and Figure 13 The vertical U / V-shaped groove 531 on the outer wall of the finger sleeve shown in F does not necessarily need to be uniformly implemented as a central chord. Figure 10 The outward line shown in the two-dimensional view of D can be straight, inward, or outward at different vertical heights of the finger sleeve wall. For example, the middle chord of the vertical U / V-shaped groove can follow the middle finger sleeve section. Figure 10 The straight shape 500C in C or Figure 10 In E, the inward line 501C helps to generate a ratio Figure 10 The outward-facing line 503C in E provides greater clamping force. The middle chord of the vertical U / V groove may transition to the outward-facing line towards the opening of the top finger sleeve. The inward-facing vertical U / V groove implemented on the finger sleeve can help generate greater clamping force, especially for a single inserted finger (such as the thumb or index finger).

[0507] Figure 13 E and Figure 13 The vertical U / V-shaped groove 531 on the outer wall of the finger sleeve shown in F does not need to be implemented at a uniform depth along the finger sleeve wall. For example, the vertical U / V-shaped groove can be deeper in the upper middle part of the finger sleeve wall and shallower towards the lower part of the finger sleeve wall (see...). Figure 13 (The expanded window view of F), and disappears near the end of the finger sleeve.

[0508] Embedding vertical U / V-shaped grooves along the outer wall of each finger sleeve can help enhance the overall vertical stiffness of the SHWT glove, reducing the likelihood of the SHWT glove collapsing during finger insertion, especially when horizontal U / V-shaped grooves are also implemented in the SHWT glove, thus reducing vertical stiffness.

[0509] Vertical U / V-shaped grooves embedded in the outer wall of the finger sleeve allow for adaptability and expandability in the cross-sectional perimeter of the top skirt. (Reference) Figure 21 C, the top skirt begins above 100f-H. Although there is a wall thickness of 505 between the top edge of the finger cot and the top skirt, this thickness is negligible when considering the expandability of the vertical U / V-shaped groove extending from the top edge of the finger cot to the top skirt. The expandable top skirt allows the hand to open with less force because the hand is less constrained by the expandable top skirt.

[0510] In this case, the structural tensile / expansion limit of the palm protection segment may be extended, and the hand may be primarily limited by the structural tensile / expansion limit based on arc C and arc B.

[0511] on the one hand, Figure 1 SHWT gloves 100 in A can be as follows Figure 16 The SHWT glove 136 in D is shown, with the addition of a vertical U / V groove 531 and a horizontal U / V groove 530. The vertical U / V groove 531, shown in a solid circle, extends from the horizontal U / V groove 530, and together with the vertical U / V groove 531 shown in a dashed circle on the finger sleeve wall, further extends the perimeter of the top skirt and expands the range of fit for the top skirt size. Therefore, the SHWT glove 136 has a greater... Figure 13 The SHWT Gloves 130 in the E series features a more expandable top skirt.

[0512] The SHWT Glove 136 features adaptive finger cots, an adaptive top skirt, and adaptive HUV arc C and HUV arc B lengths. With its adaptive, expandable arc C and arc B lengths, the SHWT Glove 136 can grasp large spherical objects through inter-finger grip and center grip.

[0513] Another advantage of implementing both vertical and horizontal U / V grooves in SHWT gloves is that when SHWT gloves use inelastic but flexible Type I materials (such as paper), the vertical and horizontal U / V grooves can add elasticity to the inelastic material to meet the design standards of SHWT gloves.

[0514] Figure 11 B shows a cross-sectional view of the finger sleeve of the SHWT glove 130, which has vertical U / V-shaped grooves (531C in the cross-sectional view) on its outer wall, and further vertical U / V-shaped grooves (531C in the cross-sectional view) added to each side of the finger sleeve. As shown in the dashed window on the left, adding the vertical U / V-shaped grooves can be seen as mirroring an extended pointed corner (a single dashed "V") along the central dashed line and connecting this mirrored corner to the finger sleeve at the mirror line (see the dashed window on the left), thus forming two vertical U / V-shaped grooves (shaped like connected double "Vs"). When counting the number of grooves, only convex grooves are counted. Concave grooves are not included in the count. The definitions of convex and concave shapes will be discussed in later sections. Figure 11 The finger sleeve in B is linearly symmetrical, so there are a total of 4 vertical U / V shaped grooves on the side of the finger sleeve.

[0515] Figure 11 Figure B shows the finger cot of the SHWT glove 130, which has vertical U / V grooves (531C in cross-sectional view) on its outer wall. The finger cot has a width (OW) and a height (OH). OWae represents the width of the finger cot when each side has a single extended apex (shown as a dashed line). OWa represents the width of the finger cot when two vertical U / V grooves (531C in cross-sectional view) are added to each side. The endpoint of OWa on each side is at 1 / 2 PV-W (half the distance between the peak and trough of the U / V groove). When the finger cot has U / V grooves, the width and height of the finger cot's cross-section will be measured in detail later. OWa will be less than OW and OWae. With the same height (OH) and reduced width (OWa), the width (OW) to height (OH) ratio of a finger sleeve with a vertical U / V groove on each side is less than the width-to-height ratio of a finger sleeve with a single extended apex on each side or a finger sleeve without a vertical U / V groove on each side.

[0516] Adding vertical U / V-shaped grooves to the sides of the finger sleeves can help reduce the width of the finger sleeves for a better fit to a single inserted finger, and structurally acts similarly to a corner bar structure to enhance the vertical stiffness of the finger sleeves. This structural improvement can be helpful when SHWT gloves are made of thin and less elastic or non-elastic materials (such as paper).

[0517] On the one hand, vertical U / V-shaped grooves are added to both sides of the finger sleeve to replace the relatively rounded side corner ends (e.g. Figure 10 The side corner of the finger sleeve in the SHWT glove 100 shown in Figure A can further increase the range of finger sizes, the number of fingers, or both the range of finger sizes and the number of fingers that the SHWT glove can accommodate.

[0518] On the one hand, each side of the finger sleeve includes two pointed side angles (such as...). Figure 10 (As shown in the expanded window in C) can achieve the same effect as adding two vertical U / V grooves (such as... Figure 11 Similar to the effect shown in 531C (B), this allows for adaptation to the finger sleeve circumference and reduction in finger sleeve width. This aspect may be useful for SHWT gloves based on non-elastic or low-elastic materials (e.g., paper-based SHWT gloves).

[0519] Figure 11 The dashed window on the right side of B also shows an example of adding three U / V grooves to the side of the finger cot by folding a single point twice.

[0520] The vertical U / V grooves on the sides of the finger sleeve can be implemented at different vertical heights on the finger sleeve wall with varying groove depths. As an illustrative example, the vertical U / V grooves can be implemented at a certain depth around the middle section of the finger sleeve, gradually becoming shallower towards the top opening and / or bottom finger sleeve section, and may eventually disappear near 100% finger sleeve height (SH) and / or near 0% finger sleeve height (SH).

[0521] Compressible or foldable SHWT gloves (including, for example, paper SHWT gloves) can be compressed or folded for purposes such as transportation, storage, and bulk packaging. On the other hand, glove measurements (e.g., finger width (OW), height (OH), finger height (SH), ratio, etc.) can be performed when the SHWT glove is unfolded and expanded into a wearable state (shape).

[0522] On the one hand, considering the clamping force of a finger sleeve when one or more fingers are inserted into a given finger sleeve, the cross-sectional design of the finger sleeve can be described by the ratio of the width (OW) to the height (OH) of the cross-section of the finger sleeve at different finger sleeve heights, as described below.

[0523] Figure 21 D shows the outer surface of the finger sleeve, with cross-sections shown at different percentages of finger sleeve height (SH). These cross-sections can have different shapes depending on their location. Figure 21 E shows a set of certain cross-sectional views. On the one hand, in Figure 21 The three-dimensional view of D shows a cross-section at 70% finger sleeve height (SH), while Figure 21Figure E shows the two-dimensional shape of the finger sleeve at 70% of its height (SH). On one hand, from... Figure 21 The cross section of D is Figure 21 E can be represented as a planar shape (two-dimensional). On the one hand, from Figure 21 The cross section of D is Figure 21 In E, it may not be shown as a planar shape (two-dimensional).

[0524] If the wall thickness of the finger sleeve is approximately the same along the cross-sectional perimeter, the width (OW) and height (OH) can be measured from the inner surface of the finger sleeve, because the ratio of width (OW) to height (OH) is the same as the ratio obtained from the outer surface of the finger sleeve, or the difference is negligible.

[0525] For the following description of the cross-sectional shape of the finger sleeve, the width (OW) and height (OH) are measured from the outer surface of the finger sleeve.

[0526] Figure 22 , Figure 23 and Figure 24 It can include multiple points, such as points "A", "a", "b", "b'", "c", "c'", "d", "d'", "e", "f", "g", "h", "i", "j", etc. For example, a point can be specified as point b or b, or point h or h. An arc can be specified by two points, such as arc ab. An angle can be specified by three points, such as angle d(e)f. A line segment can be specified by two points, such as gh. A line segment is, for example, in... Figure 22 The cross-sectional shape of B is referenced, which has straight line segments from point "g" to point "h" (referenced as gh) and from point "i" to point "j" (referenced as ij).

[0527] finger sleeve cross-sectional shape

[0528] The cross-sectional shape of the finger sleeves in SHWT gloves can be geometrically considered as a single closed loop shape, which is composed of connecting segments of various arcs / angles, such as... Figure 22 As shown in Figure A (arc / angle a to e or a' to e'). Geometrically, a closed-loop shape can contain one or more loops; for example, the number "8" is a closed-loop shape with two loops. The cross-sectional shape of the finger sleeve in the SHWT glove has a single loop.

[0529] like Figure 22 As shown in A, the arc / angle segments can be pure arc segments (e.g., segments a and e), arcs mixed with straight line segments (e.g., segments c and d), or angles formed by two straight line segments (e.g., segment b). These segments can be convex ( Figure 22 All segments above the dashed tangent in A) or concave ( Figure 22(All segments below the tangent in A). Convex means curving outward to form a dome or apex. Concave means curving inward, like the inside of a bowl, and can be filled. Figure 22 The right side of A shows an example structure when convex and concave arc / corner segments are connected together. The horizontal and vertical U / V grooves discussed earlier are examples of connected convex and concave arc / corner segments. When deformed by external forces (such as fingers inserted into finger sleeves), arc / corner segments may be stretched into straight segments, and therefore they can be considered as expandable structures, while a single straight segment is not geometrically expandable (ignoring material stretching).

[0530] On one hand, SHWT gloves based on three-finger cots can have a flat, single closed-loop finger cot cross-sectional shape at a position below 70% of the finger cot height (SH). On the other hand, SHWT gloves based on four-finger cots can have a finger cot cross-sectional shape defined as a flat, single closed-loop shape at a position below 50% of the finger cot height (SH). The term "flat" means that the ratio of its width (OW) to its height (OH) is greater than 1:1, or that its width (OW) is greater than its height (OH). In the following description, the flat, single closed-loop shape is referred to as a flat ring shape.

[0531] Flat ring shapes can be divided into: 1) flat convex rings, which are flat ring shapes with only convex arc / corner segments; or 2) flat hybrid rings, which are flat ring shapes with a mixture of convex and concave arc / corner segments. Both convex and hybrid rings can contain straight line segments because... Figure 22 The arc / angle segment shown in A may contain straight line segments as part of the arc / angle segment (e.g., segments b, c, d). In the following description, for clarity, straight line segments may be described separately from connected arc / angle segments.

[0532] Figure 22 B illustrates a flattened convex ring containing convex arcs ab, bf, fg, hi, and ja, and two line segments gh and ij. On one hand, Figure 10 The approximately flattened ellipse shown in B, if lacking horizontal or vertical U / V grooves and / or concave arc segments, could be a flattened convex ring. The term "approximately" is used with ellipse because an ellipse does not have a strict mathematical definition.

[0533] Figure 22 Figure C shows a flat hybrid ring with convex arcs ab, bc, fg, hi, and ja, a convex angle d(e)f, a concave arc cd, and two straight line segments gh and ij. The concave arc cd and the two adjacent convex arcs bc and convex angle d(e)f can be considered as adding vertical U / V grooves to the finger sleeve from point b to point f. The folds in the vertical U / V grooves allow the finger sleeve to extend or open like an accordion extension. Figure 10 D、 Figure 10 E, Figure 11 The cross-sectional shape in B is an example of a flat hybrid ring.

[0534] On the one hand, connected convex and concave arc / angle segments do not necessarily need to be directly connected. Convex and concave arc / angle segments can be connected by straight line segments.

[0535] Whether the flat ring shape is a hybrid ring or a convex ring will affect how much the width (OW) and height (OH) of the SHWT finger sleeve can be extended to accommodate the circumference of multiple inserted fingers when the finger is inserted into the finger sleeve (see [reference]). Figure 2 (D-expand window) or the circumference and shape of a single inserted finger (see...) Figure 2 (Thumb 211C in D).

[0536] Distinguishing between convex rings and hybrid rings – Tangent test

[0537] Besides visual inspection, one way to distinguish between convex rings and mixed rings is by using a tangent test. Figure 22 A shows a curve starting from point A on the tangent, which turns left (or counterclockwise) or right (or clockwise). Alternatively, the straight line segment starting from point A may not turn along the tangent direction. The tangent test method for identifying convex rings and mixed rings is as follows... Figure 22 B and Figure 22 As shown in C.

[0538] Figure 22 The flattened convex ring shown in B starts at point "a", proceeds to the right (or clockwise) in the direction of the arrow, passes through b and f, reaches points g, h, i, and j, and then returns to a. Each arc and straight line segment along the way always turns right or clockwise (in this particular example) from its respective tangent (the dashed line), or remains on the tangent without turning left (or counterclockwise) away from the tangent (or crossing to the other side of the tangent). Reversing the direction, in other words, will... Figure 22 The arrow in B points in the opposite direction on the flat convex ring, and all arcs and straight line segments will turn to the left (or counterclockwise) or not turn at all.

[0539] Figure 22 The flat convex ring in B has curves that start from points a, b, f, h, j and turn to the right or clockwise (following the direction of the arrows on the flat convex ring) from their respective tangents, and two straight line segments that start from points g and i and follow their tangents to their respective endpoints h and j.

[0540] Note: When using a tangent test to measure the angle formed by two line segments, for example... Figure 22 The angle l(m)n to the right of B, starting from the vertex (m), we use the extension of line lm as the tangent to determine the next line segment mn, which turns right in this example.

[0541] Figure 22 The flat mixed loop in C starts at point "a" and, following the direction of the arrow, the convex arcs ab and bc turn right (or clockwise) from their tangents. As the curve continues from c to d, it turns left (or counterclockwise) from its tangent (or crosses to the other side of the tangent) and forms a concave arc. Then, starting from d, it turns right (or clockwise) again along the straight line segment to e. Starting from e, it turns right (or clockwise) along the straight line segment to f, forming the convex angle d(e)f. Therefore, if the arc / angle segment of the cross-section of the finger sleeve begins to turn right (or clockwise) from the tangent and then turns left (or counterclockwise) from the tangent (i.e., crosses to the other side of the tangent), it is a mixed loop. Similarly, if the arc / angle segment of the cross-section of the finger sleeve begins to turn left (or counterclockwise) from the tangent and then turns right (or clockwise) from the tangent, it is also a mixed loop. The mixing ring has at least one convex arc / corner segment and at least one concave arc / corner segment. Reversal Figure 22 The direction of the arrow in the C-flat hybrid ring will yield the same result.

[0542] Definitions of OW and OH of a convex ring

[0543] In a convex ring, for example Figure 21 E and Figure 23 The convex ring shown in C is positioned in an XY coordinate system, where the y-axis is parallel to the bottom clamping radius (BRC) at 0% finger height (SH), or parallel to the clamping radius (RC) at non-0% finger height (SH) (see [reference]). Figure 13 C and Figure 13 D. Understand the definitions of RC and BRC. The ring height (OH) is parallel to the Y-axis and is the distance between the highest and lowest points on the cross-section of the finger sleeve on the Y-axis. The ring width (OW) is the distance between the leftmost and rightmost points on the finger sleeve on the X-axis.

[0544] Definitions of OW and OH in mixed rings

[0545] The height (OH) and width (OW) used in hybrid rings differ from those used in convex rings. In hybrid rings, for example... Figure 24 A I&II、 Figure 24 B and Figure 24 In the mixed ring shown in C, when both convex and concave arc / corner sections exist at the top or bottom of the cross-section, the start and end points of the height (OH) may not be the highest and lowest points on the finger sleeve shape. When both convex and concave arc / corner sections exist on the left or right side of the finger sleeve shape, the start and end points of the width (OW) may not be the leftmost and rightmost points on the finger sleeve shape.

[0546] Figure 24Figures A, B, and C show a series of flat hybrid rings, which are cross-sections of finger sleeves and can be configured to change shape or deform when one or more fingers are inserted into the finger sleeve.

[0547] Figure 24 AI illustrates a concave arc a(b)c. As this segment expands, arc a(b)c will extend towards a straight line. Therefore, the height (OH) begins at "1 / 2 PV-H" (the midpoint between the highest of the two peaks a or c and the valley b) and ends at the bottom. Figure 24 In the diagram, all PV-H represent peak-valley heights, PV-W represent peak-valley widths, and S-PV-H represent minor peak-valley heights.

[0548] Figure 24 A II shows two concave arcs, de and ef. The height (OH) begins at “1 / 2 PV-H” (the midpoint between the peak point e and the lowest of the two valley points d or f) and ends at the bottom.

[0549] Figure 24 B illustrates a U / V groove, such as segment efb attached to the expanded window of concave segment acb. The “PV-H” of segment acb begins at 1 / 2 S-PV-H of segment efb (as shown in the expanded window) and ends at valley point c of segment acb. The height (OH) begins at “1 / 2 PV-H” of segment acb and ends at the bottom.

[0550] Figure 24 C shows a T-shape with concave angles a(b)c and d(e)f, connected to convex angles b(c)d and c(d)e. The height (OH) starts from the top and ends at “1 / 2 PV-H” (the midpoint between the level of the concave angle segment ab or ef and the level of the convex angle segment cd).

[0551] Figure 24 The width (OW) in C begins at 1 / 2 PV-W on the left (the midpoint between peak point a and valley point b in concave angle a(b)c) and ends at the midpoint between f and e in concave angle f(e)d.

[0552] Definition of convex ring sharp arc / angle – Partial inscribed circle sweep test

[0553] The sharpness of the arc / corner segment in the flat convex ring affects how much the width (OW) and height (OH) can change to conform to the circumference of multiple inserted fingers 210 or the circumference and shape of a single inserted finger when the finger is inserted (see [link to finger sleeve]). Figure 2 D、 Figure 2 C and Figure 11D). The ratio of the width (OW) to the height (OH) of the finger sleeve cross-section of a flat ring varies depending on how many sharp arc / corner segments it contains. The term "sharp arc / corner segment" in flat rings (different from the usual definition of "sharp") is determined based on the Partial Inscribed Circle Sweep (PICS) test described below. The test circle used in the PICS test may not have a tangent point with every segment in the ring, but will have at least one point of contact with the ring.

[0554] By definition, the PICS test is used to determine how many sharp arc / corner segments a flattened convex ring contains, and in Figure 22 D and Figure 23 The PICS test can be performed by starting at the center and sweeping outwards, or by starting at one end, moving to the center, and then to the other end. The PICS test can begin with the smallest arc / corner segment within the convex ring and continue until the entire convex ring is covered.

[0555] On the one hand, the radius of the test circle is <= OH / 2, but > 0. In the case of a flat convex ring with only arc segments (or no corner segments), the minimum test circle can have a radius equal to the minimum arc radius in the convex ring. If the minimum arc / corner segment in the convex ring is formed by two straight line segments, or a corner segment formed by a straight line segment and an arc connected at the corner tip (e.g.) Figure 22 (segments c and d in A), then the minimum test circle can have an initial radius of 1% OH / 2.

[0556] For simplicity, an "S" can be used before the arc / angle segment to indicate a "sharp arc / angle segment" according to our definition; for example, sharp arc ab will be abbreviated as "Sab". In the following description, sharp arc / angle segments will be referred to as "S" segments. Sharp arc / angle segments that contain sub-sharp arc / angle segments are defined as compound sharp arc / angle segments. Compound sharp arc / angle segments will be referred to as compound "S" segments. Sharp arc / angle segments that do not contain sub-sharp arc / angle segments are defined as simple sharp arc / angle segments. Simple sharp arc / angle segments will be referred to as simple "S" segments.

[0557] Figure 22 The flat convex ring in D has a left arc ab, which in the expanded window consists of a larger arc ac with radius r2 and a smaller arc bc with radius r1. Arc bc is the arc with the smallest radius in this convex ring.

[0558] exist Figure 22 In D, a test circle can have a radius r1. When the radius of the test circle is equal to the radius of arc bc, a portion of the test circle overlaps with arc bc, as shown in the expanded window. The overlapping section between the test circle and the convex ring is equivalent to having a contact point. A test circle with radius r1 contains only one overlapping section bc, but an overlapping section is equivalent to a contact point.

[0559] Other examples of overlapping sections equivalent to a single contact point are in Figure 23 As shown in D IV, the left convex ring has a test circle that creates overlapping segments ab, contact points c and d. This test circle divides the convex ring into three "S" segments: Sbc, Scd, and Sad. The right convex ring has a test circle that creates two overlapping segments ij and kl, and a contact point h. This test circle divides the convex ring into three "S" segments: Shi, Sjk, and Slh.

[0560] like Figure 23 D and Figure 22 As shown in D, the contact points and overlapping sections generated by the test circle within the convex ring are equivalent in dividing the convex ring into "S" segments. A test circle with two contact points (either contact points or overlapping sections) will divide the convex ring into two "S" segments, while a test circle with three contact points will produce three "S" segments.

[0561] The length of the "S" segment between two adjacent contact points is always longer than the length of the test circle segment between two adjacent contact points. For example, Figure 22 The solid-line convex shape D has a test circle that generates contact points m and n at the center, thus producing Smdacben and Smd'c'b'e'n. The length of each "S" segment between its two adjacent contact points is longer than the length of the test circle segment. In another example, such as... Figure 23 As shown by the convex ring on the left side of D IV, Sbc is an "S" segment, and the segment length of Sbc is greater than the segment length of the test circle between points b and c. Figure 23 As shown by the convex ring on the right side of D IV, Sjk is an "S" segment, and the segment length of Sjk is greater than the segment length of the test circle between points j and k.

[0562] Refer again Figure 22 D, The PICS test starts with a solid circle with radius r1 on the left and then moves to the next test circle with an increasing radius (dashed circle). It produces two contact points d and e and divides the flat convex ring into two “S” segments: 1) Sdcbe, 2) Sdmd'c'b'e'ne.

[0563] The test circle radius continues to increase and moves to the right. After reaching the maximum radius = OH / 2, the test circle radius begins to decrease as it moves to the right until it reaches the right end of the flat convex ring. Along the sweep path, except for the first and last test circles (radius r1), which each produce only one overlapping segment (bc and b'c'), each of the remaining test circles produces only two contact points within this flat convex ring, dividing the convex ring into two "S" segments. Since the sweep path covers the direction of all "S" segments and no test circle produces more than two contact points, each "S" segment is a simple "S" segment. Figure 22 The flat convex ring (solid line shape) in D has only two simple "S" segments from the same test circle. On the one hand, replacing the arc dmd' with the sharp angle d(h)d' and applying the PICS test, the middle test circle (in Figure 22 D (shown as a circle with a solid circumference) will generate three contact points g, i, and n, dividing the flat convex ring into three "S" segments: 1) Sg(h)i at the top center, 2) Sgdacben on the left, and 3) Sid'c'b'e'n on the right. Figure 22 The modified flat convex ring with Sg(h)i shown in D has three "S" segments (and) from the same test circle. Figure 22 (Compared to the original solid-line flat ring with two "S" segments). Continuing to sweep towards each "S" segment, no more than two contact points are generated in the remaining test circles. Therefore, the modified flat ring has three simple "S" segments from the middle solid-line test circle. Note that, according to the definition using PICS testing, a flat ring with a width (OW) greater than its height (OH) has at least two simple "S" segments.

[0564] Figure 23 A shows another flat convex ring, applied using the PICS test, with all sweep directions indicated by dashed arrows. Figure 23 A shows the complete PICS test sweep trajectory. Figure 23 B. Figure 23 C and Figure 23 D shows the PICS test and its results in steps.

[0565] exist Figure 23 In section A, starting from the bottom left corner, the test circle overlaps with the corner. (Note that this test circle only overlaps with the convex ring by one segment, but one overlapping segment is equivalent to one contact point). Then, following the direction of the arrow, we gradually increase the radius of the test circle, maintaining two contact points until the test circle encounters three contact points at points a, b, and c. The three contact points a, b, and c generate three "S" structures, Sab, Sbc, and Sca, as shown... Figure 23 As shown in B(I). Continuing with the PICS test will identify... Figure 23A shows a simple "S" segment in the convex ring.

[0566] exist Figure 23 In B(I), since the PICS test starts from Sab, which is a simple "S" segment, the test continues by moving the test circle towards Sbc (arrow pointing to the upper left), decreasing its radius until it overlaps with the end of Sbc, as shown. Figure 23 As shown in the dashed elliptical window D(II), the PICS test towards Sbc along the sweep did not produce more than two contact points, and Sbc is a simple “S” segment.

[0567] exist Figure 23 In B(I), the test circle continues to move to the right along the Sca direction, and its radius increases. Three new contact points d, l, and n (see...) Figure 23 A and Figure 23 B II) Divide the flat convex ring into Sdn, Sdl, and Sn(m)l, as follows Figure 23 As shown in B(II). This indicates that Sca (in Figure 23 B(I) is a composite "S" segment because it contains sub-"S" segments Sdl and Sn(m)l. (Note: Sdl and...) Figure 23 The Sdl-s in DI are different.

[0568] Since the sweeping begins from the left, therefore in Figure 23 In B(II), the sweeping continues toward Sn(m)l and Sdl. The PICS test continues toward Figure 23 In B(II), Sn(m)l confirms that Sn(m)l is a simple “S” segment because no more than two contact points are generated at Sn(m)l along each test circle swept.

[0569] Next, the PICS test continues towards Figure 23 In B II, Sdl, following the arrows, tests the circle radius by decreasing until it encounters three new contact points e, g, and x (see...). Figure 23 A's solid line test circle), which produces the angle Se(f)g (in Figure 23 The right-hand expandable window of A shows Sg(j)x and Sedcban(m)lx. Since the segment length of angle e(f)g minus the segment length of the test circle between points e and g is less than 1% of the segment length of the test circle between e and g, angle e(f)g is not counted as an "S" segment. This <1% exclusion rule for "S" applies to all "S" segments tested using PICS.

[0570] Skip angle e(f)g, continue the PICS test toward Sg(j)x, following... Figure 23 The top right arrow in A indicates that the radius of the test circle should be reduced until three new contact points h, i, and k are encountered (see [reference]). Figure 23 A and Figure 23 (B III), which produces Shi, Si(j)k, and Shk. (Note: Figure 23 In B(III), Shk is related to Figure 23 The same curve defined by Shgfedcban(m)lxk in A).

[0571] Since the sweeping started from the left, the sweeping continued to the right (towards Shi and Si(j)k) and confirmed that both were simple “S” segments. The PICS test stopped here because there were no more composite “S” segments.

[0572] From PICS testing Figure 23 The five simple "S" segments Sbc, Sab, Shi, Si(j)k, and Sn(m)l identified in the convex ring of A are... Figure 23 The shaded section in C is shown.

[0573] Figure 23 D(I) shows that... Figure 23 The original flattened convex ring in C is decomposed into these 5 simple "S" segments around it (shaded segments) and a new flattened convex ring at the center. Figure 23 The central flat convex ring in D(I) still has two "S" segments, Sdn-s and Sdl-s, because the intermediate test circle produces the overlapping segment nl and the contact point d. Sdn-s and Sdl-s are both... Figure 23 The simple “S” segment in D(I) is removed because all sub-“S” segments have been removed and are displayed as the surrounding 5 simple “S” segments.

[0574] exist Figure 23 In D(I), adding one of the two adjacent simple “S” segments determined from the same test circle back to the Sdn-s or Sdl-s of the central convex ring will not generate more than two simple “S” segments from the same test circle in the newly created convex ring. That is, it can still pass the PICS test without having more than two contact locations (contact points or overlapping segments) and generating more than two simple “S” segments from the same test circle.

[0575] exist Figure 23 In D(II), since Sbc and Shi are simple “S” segments and belong to two different test circles (see...), Figure 23 The two dashed circles on the left and right of C), Sbc and Shi can both be added back to Sdn-s and Sdl-s without creating more than two simple "S" segments from the same test circle in the newly created convex ring, such as Figure 23As shown in D II. However, simple “S” segments Sbc and Sba may not be able to be added back together to their original Sdn-s ( Figure 23 DI), because they belong to the same test circle (therefore only one can be added back). Similarly, Shi and Si(j)k (see Figure 23 C) also belong to the same test circle, therefore they cannot be added back together. Figure 23 Sdl-s in DI.

[0576] Figure 23 D(III) shows that if you want to... Figure 23 Add Sba and Sn(m)l back to DI Figure 23 In DI, the Sdn-s and Sdl-s of the central convex ring, without generating more than two simple "S" segments from the same test circle in the newly created convex ring, must be cut off. Figure 23 The shaded area Sdhi(j)kl in D III is because it belongs to the same test circle as Sn(m)l (which has three contact points d, n, l).

[0577] exist Figure 23 In D(III), on the one hand, you can retain Sba and replace Sn(m)l with a simple “S” segment on the test circle segment dl: or use Figure 23 In D(I), Sdl-s can be either Sdl-s plus an additional simple "S" segment, i.e. Figure 23 Shi or Si(j)k in D(I).

[0578] In a flat convex ring, when the PICS test generates three contact locations (contact points or overlapping segments) from the same test circle, resulting in three "S" segments, retaining two simple "S" segments will allow the new modified convex ring to meet the requirement of having two contact locations from the same test circle. Any composite "S" segment can be changed to a simple "S" segment by removing its sub-"S" segments but retaining one sub-simple "S" segment (from the same test circle). After this modification, the new flat convex ring will meet the requirements of the PICS test, having two contact locations and generating only two simple "S" segments from the same test circle.

[0579] Applying the PICS test, after examining all test circles in the sweep, if any test circle creates three or more contact points (contact points or overlapping segments) within the flat ring, then the flat ring has more than two simple "S" segments. If no test circle creates three or more contact points, then the flat ring has fewer than three simple "S" segments.

[0580] A flat convex ring with more than two simple “S” segments (tested by PICS) functions similarly to a flat hybrid ring in terms of having more scalable structures (designed to simulate stretchable materials).

[0581] When a finger is inserted into a finger sleeve, a flat hybrid ring or a flat convex ring with more than two simple "S" segments can have a greater increase / expansion in the width (OW) to height (OH) ratio than a convex ring with <= two simple "S" segments. Therefore, flat hybrid rings and flat convex rings with more than two simple "S" segments can use a smaller width (OW) to height (OH) ratio as defined in Table 2 because they are designs with greater expansion capabilities. Detailed ratios are shown in Tables 1 and 2 below.

[0582] For SHWT gloves with four finger sleeves, since three finger sleeves may be occupied by a single finger and the fourth finger sleeve may be occupied by two fingers (the ring finger and the partially inserted little finger), the ratio of the width (OW) to the height (OH) of the finger sleeve cross-section can be further reduced compared to SHWT gloves with three finger sleeves.

[0583] Figure 24 D shows a flat convex ring with two 90-degree angles (shaded) at the top. This is a flat convex ring with a width (OW) to height (OH) ratio of 2:1 and less than 3 simple "S" segments from the same test circle. Among all flat convex rings with less than 3 simple "S" segments from the same test circle and a width (OW) to height (OH) ratio of 2:1, Figure 24 The shape in D may have the largest perimeter.

[0584] Add the other two sharp corners Figure 24 The two bottom sides of the D-shaped convex ring are obtained Figure 24 The rectangle in E. For example... Figure 24 As shown by the dashed ellipse to the right of E, rotate the lower right corner counterclockwise by 90 degrees so that it is parallel to the upper right corner, forming two parallel inverted V-shaped structures. This is also a structure with connected convex and concave arc / corner segments. Figure 24 The right side of the lower right corner of E flips downwards in an inverted V shape, forming another structure with connected convex and concave arc / corner segments. Figure 24 In E, rotating the lower left corner clockwise creates two parallel inverted V-shaped structures on the left side of the rectangle, the same as on the right side. Therefore, in a flat convex ring, having more than one simple "S" segment on the left or right side (along the width (OW) direction) is equivalent to an expandable structure with connected convex and concave arc / corner segments in a hybrid ring. Figure 10C shows another example of a finger sleeve cross-section, which is a flat convex ring with two pointed corners on the left (shown in the dashed circle in the left unfolded window) and two pointed corners on the right. Adding two pointed corners to the side of the finger sleeve has a similar effect to adding vertical U / V grooves to the side of the finger sleeve, allowing for adaptation to the finger sleeve circumference and reducing the finger sleeve width (OW). Therefore, Figure 10 The cross-sectional shape of the finger sleeve in C uses the width (OW) to (OH) ratio in Table 2.

[0585] The design of the finger sleeves helps control the clamping force relative to the inserted single or multiple fingers. One aspect of this design is the use of a selected ratio of the width (OW) to the height (OH) of the finger sleeve's cross-section. These ratios can be selected within a range, such as 10% to 70%, 10% to 20%, 10% to 30%, or 10% to 50% of the finger sleeve height (SH). This range roughly corresponds to the PIP joints to the nail plate of the five fingers of a hand fully inserted into an SHWT glove (see [link to glove designation]). Figure 2 A. Understanding finger joint position. Controlling the clamping force within this range improves the usability and performance of the SHWT glove. The width (OW) to height (OH) ratio can have no selected range below 10% of the finger sleeve height (SH) because the finger sleeve design below 10% of the finger sleeve height (SH) may focus on matching the shape of the inserted fingertip (e.g., thumb or index finger), especially near the end of the finger sleeve. Therefore, the width (OW) to height (OH) ratio below 10% of the finger sleeve height (SH) can vary within a wide range.

[0586] The average width-to-height ratio of a single finger's cross-section from the PIP joint to the nail tip is typically in the range of 1.1:1 to 1.25:1, and may not exceed 1.28:1. Conventional finger gloves are designed with this size range in mind and incorporate ratios within that range (or slightly larger) to fit a single finger. Doubling these ratios would result in gloves that may only accommodate multiple fingers. Through numerous tests and design iterations, including analysis of hand and finger movement patterns, SHWT gloves incorporate finger sleeves with the ratios described below. As previously mentioned, the benefits of SHWT gloves include single or multiple finger insertion and usability, as well as single-handed removal (for a single finger per finger sleeve and for inserting multiple fingers into one or more finger sleeves). These benefits are not present in conventional gloves, which are designed to fit the average user's hand or fingers, not those benefits of SHWT gloves. Using the width and height of the user's fingers as a design reference, the width (OW) to height (OH) ratio of the finger sleeve cross-section can be larger to allow for the creation of... Figure 2The sufficient finger sleeve side gap 218a shown in D allows for two parallel inserted fingers and is consistent with the benefits of SHWT gloves. The width (OW) to height (OH) ratio of the SHWT glove can be determined when the SHWT glove is in a neutral position, such as on a flat horizontal surface with the finger sleeve ends on the surface and no user's hand inside (which also means that the finger sleeve body is not deformed by the insertion of fingers).

[0588] Table 2

[0589] a) The cross-section of the SHWT glove finger sleeve is a flat convex ring as tested by tangent and has >2 simple "S" segments as tested by PICS; or

[0590] b) The cross-section of the SHWT glove finger sleeve is a flat mixed ring as determined by tangent testing.

[0591]

[0592] like Figure 8 As shown in E (top), on the one hand, the cross-section of the SHWT finger sleeve can be triangular in shape between 20% and 70% of the finger sleeve height (SH). Figure 10 A, Figure 10 C and Figure 10 D shows several examples of triangular finger sleeves. Each of these examples has two straight line segments on its inner wall that are 120 degrees apart. Figure 13 C illustrates that the straight segments of the triangular finger sleeves of the SHWT glove 100 are parallel to the UC line. Two adjacent finger sleeves of the SHWT glove 100 form a parallel inverted U-shaped channel, and the straight segments facing each other on the adjacent finger sleeves form two parallel flat surfaces. During use, such as when the hand makes a gripping motion, the parallel flat surfaces can merge together, which can increase the gripping contact area between the target object and the finger sleeves and help increase friction. For a four-finger-based SHWT glove with a triangular finger sleeve cross-section, forming a parallel inverted U-shaped channel, the two straight segments on the inner wall of the finger sleeve will be 90 degrees apart.

[0593] On the one hand, such as Figure 20 A, Figure 20 B and Figure 20The triangular finger cot shown in C is similar to the triangular finger cot of SHWT glove 100, but in a three-finger-based SHWT glove, the inner wall of the triangular finger cot may not have straight segments, or the straight segments may not be 120 degrees apart (or 90 degrees apart in a four-finger-based SHWT glove).

[0594] The rectangular bar test can identify triangular-shaped finger sleeves (cross-section) in SHWT gloves. Any additional structures added to the finger sleeves (such as printed patterns) should be excluded from the rectangular bar test. Figure 20 A, Figure 20 B and Figure 20 D illustrates a rectangular bar test in a finger sleeve with only convex segments on the inner wall. Figure 20 C illustrates a rectangular bar test in a finger sleeve that has both convex and concave sections on its inner wall.

[0595] refer to Figure 20 In the left image (A), in a three-finger SHWT glove, the three finger cots are moved towards the glove center (GC) (shown as a reference center circle) until every two adjacent finger cots contact at the contact point "tp," as shown in the expanded window on the right. The length "L" is defined as the distance from the glove center (GC), marked 0% L, to the outer tips of the two contacting finger cots, marked 100% L. If the outer tip of one finger cot is higher than its adjacent finger cot, the average height of the outer tips of the two finger cots can be used as 100% L. Figure 20 B and Figure 20 The same rule is used in C to define the length "L".

[0596] exist Figure 20 A and Figure 20 As shown in the expanded window of B, in a finger sleeve with only convex segments on its inner wall, a rectangular bar with a length of 1 / 2 L and a width of 1 / 20 L will be used to test the triangular shape. The aspect ratio of this rectangular bar is (1 / 2)L / (1 / 20)L = 10:1. This rectangular bar has an outer "e", a central side "c", and a midline "m".

[0597] exist Figure 20In A, the contact point "tp" formed by the two straight line segments of adjacent finger sleeves is located within the range of >=75% L to <=100% L. In this case, the rectangular bar is centered, and its outer side "e" is located at 100% L. The straight line segment on the inner wall of the left-hand finger sleeve intersects the central side "c" of the rectangular bar. Repeating the same test on the left-hand finger sleeve and its other adjacent finger sleeve yields the same result. Therefore, the left-hand finger sleeve is triangular. If we replace the straight line segment of the left-hand finger sleeve with the dashed arc A, then arc A does not intersect the central side "c" but intersects the rectangular bar on its long side. This new finger sleeve shape with arc A will not be considered triangular. When point tp is located within the range of >=75% L to <=100% L, if its inner wall intersects the central side "c" in every rectangular bar test with each adjacent finger sleeve, then the finger sleeve is considered triangular.

[0598] exist Figure 20 In section B, the contact point "tp" formed by the two near-flat arcs of adjacent finger sleeves is located within the range of >=50% L to <75% L. In this case, the rectangular bar is positioned in the center, with its line "m" intersecting "tp". For example... Figure 20 As shown in the magnified window (B), the near-flat arc segment of the left-hand finger sleeve intersects the outer "e" and central "c" of the rectangular bar. Repeating the same test on the left-hand finger sleeve and its other adjacent finger yields the same result. Therefore, the left-hand finger sleeve is triangular. When tp is within the range of >=50% L to <75% L, if its inner wall intersects both the outer "e" and central "c" in every rectangular bar test performed with each adjacent finger sleeve, then the finger sleeve is considered triangular.

[0599] exist Figure 20 In section B, if the near-horizontal arc finger sleeve segment is replaced with the dashed curve arc A, then arc A intersects the long side of the rectangular bar at two points. The new finger sleeve shape with the dashed arc A will not be considered a triangular shape.

[0600] When the "tp" point in a finger sleeve with only a convex section on the inner wall is located in the range of >=25% L to <50% L, it is applicable. Figure 20 The same rectangular bar test is shown in B. The rectangular bar is centered, with line "m" intersecting "tp". In this case, if its inner wall intersects the outer "e" in each rectangular bar test with each adjacent finger sleeve, then the finger sleeve is considered triangular.

[0601] like Figure 20As shown in Figure C, for finger sleeves with both convex and concave sections on the inner wall, a three-block rectangular bar is used to test the triangular shape. This rectangular bar can have a length = 3 / 4 L and a width = 3 / 32 L, meaning the aspect ratio of the rectangular bar is (3 / 4)L / (3 / 32)L = 8:1. The rectangular bar has an outer block "E", a middle block "M", and a base block "B", each with a length = 1 / 4 L. In finger sleeves with both convex and concave sections on the inner wall, when there is more than one contact point, the outermost point tp facing 100% L is used as a reference. The rectangular bar is positioned such that its outer "e" is located at 100% L and centered at the contact point of two finger sleeves.

[0602] When the outermost tp point is located in the range of >=75% L to <=100% L, such as Figure 20 As shown in C, if the inner wall of the finger sleeve enters block "M" or "B", and the same result is obtained when the same test is repeated on another adjacent finger sleeve, then the finger sleeve is considered triangular. When the outermost tp is in the range of >=50% L to <75% L, if the inner wall of the finger sleeve enters block "E" or "B", and the same result is obtained when the same test is repeated on another adjacent finger sleeve, then the finger sleeve is considered triangular. When the outermost tp is in the range of >=25% L to <50% L, if the inner wall of the finger sleeve enters block "E" or "M", and the same result is obtained when the same test is repeated on another adjacent finger sleeve, then the finger sleeve is considered triangular.

[0603] Figure 20 D shows the finger cot 231C of the SHWT glove 230 (also shown). Figure 8 E and Figure 10 (B) The test using a rectangular bar for a finger sleeve with only convex segments on the inner wall is not considered to be triangular because the inner wall of the finger sleeve does not contact the central side "c" and the outer side "e" of the rectangular bar, but intersects the long side of the rectangular bar outside of "c" and "e".

[0604] When the % L test range of a finger sleeve and one of its adjacent finger sleeves is different from the % L test range of the finger sleeve and the other adjacent finger sleeve, for example, the finger sleeve with one adjacent finger sleeve is in the range of >=75% L to <=100% L, while the finger sleeve with another adjacent finger sleeve is in the range of >=50% L to <75% L, each side should follow the rectangular bar test rules for its respective test range, and the test results of both sides will be used to determine the triangular shape.

[0605] On the one hand, an adjustable angle ruler or a 360-degree T-shaped bevel gauge can be used to test whether the cross-section of the SHWT finger sleeve is triangular.

[0606] Figure 20 C illustrates the use of an angle gauge to test whether the cross-section of a finger glove is triangular. For a rotationally symmetric SHWT glove based on a three-finger glove, the angle gauge is set to 120 degrees; for a rotationally symmetric SHWT glove based on a four-finger glove, the angle gauge is set to 90 degrees. Figure 20 In the example in C, the angle ruler is set to 120 degrees. The vertex of the angle ruler lies on the clamping radius (RC), and both sides of the ruler are parallel to the corresponding UC lines. The angle ruler is moved along the clamping radius (RC) toward a finger sleeve until each side of the ruler contacts at least one point "tp" on the inner wall of the finger sleeve. Figure 20 Figure C shows a cross-section of a finger sleeve with both convex and concave sections on its inner wall. When there are multiple contact points on one side of the angle scale in a finger sleeve with both convex and concave sections on its inner wall, the contact point located closest to the outer end of the finger sleeve (or furthest from the glove center (GC)) is considered to be tp.

[0607] After generating tp with the angle ruler and the inner wall of each finger sleeve, we can find L, starting from the apex of the angle ruler, along one side of the ruler, and ending at the outermost end of the finger sleeve. The starting point of L is defined as 0% L, and the ending point of L is defined as 100% L. This L is equivalent to about Figure 20 A, Figure 20 The rectangular bar method in B and Figure 20 L is described in the C expand window.

[0608] For a finger sleeve with only convex segments on its inner wall, when tp is in the range of >=75% L to <=100% L, if any distance X from the angle ruler side to the point on the inner wall of the finger sleeve at 50% L is less than 1 / 40L, then the cross-sectional shape of the finger sleeve is triangular.

[0609] For a finger sleeve with only convex segments on its inner wall, when tp is in the range of >=50% L to <75% L, if any distance X from the angle ruler side to the points on the inner wall of the finger sleeve at tp - 25% L and tp + 25% L is less than 1 / 40 L, then the shape of the cross-section of the finger sleeve is triangular.

[0610] For a finger sleeve with only convex segments on its inner wall, when tp is in the range of >=25% L to <50% L, if any distance X from the angle ruler side to the point on the inner wall of the finger sleeve at tp + 25% L is less than 1 / 40 L, then the cross-sectional shape of the finger sleeve is triangular.

[0611] For finger sleeves with only convex segments on the inner wall, the 1 / 40 L threshold for testing the distance X of the triangle shape is half the width of the rectangular bar (1 / 20 L) used to determine the triangle shape when the finger sleeves converge at the center (GC) of the glove, as previously discussed.

[0612] For a finger sleeve with both convex and concave sections on its inner wall, when tp is located in the range of >=75% L to <=100% L, for both sides of the angle gauge, if any distance X from the angle gauge side to a point on the inner wall of the finger sleeve ranging from >=25% L to <=75% L is less than 3 / 64 L, then the cross-sectional shape of the finger sleeve is triangular. The test range of distance X from 25% L to 75% L is equivalent to... Figure 20 Rectangular bar M+B in C.

[0613] For a finger sleeve with both convex and concave sections on its inner wall, when tp is within the range of >=50% L to <75% L, for both sides of the angle gauge, if any distance X from the angle gauge side to a point on the inner wall of the finger sleeve within the range of >=25% L to <=50% L, or to a point on the inner wall of the finger sleeve within the range of >=75% L to <=100% L, is less than 3 / 64 L, then the cross-section of the finger sleeve is triangular. The test range of distance X from 25% L to 50% L is equivalent to... Figure 20 The rectangular block B in C, with a distance X ranging from 75% L to 100% L, is equivalent to the test range of... Figure 20 Rectangular bar E in C.

[0614] For a finger sleeve with both convex and concave sections on its inner wall, when tp is within the range of >=25% L to <50% L, if any distance from the angle ruler side to a point on the inner wall of the finger sleeve within the range of >=50% L to <=100% L is less than 3 / 64 L, then the cross-section of the finger sleeve is triangular. The test range of distance X from 50% L to 100% L is equivalent to... Figure 20 The rectangular bar block M+E in C.

[0615] For finger sleeves with both convex and concave sections on the inner wall, the 3 / 64 L threshold for testing the distance X of the triangle shape is half the width of the rectangular bar (3 / 32 L) used to determine the triangle shape when the finger sleeves converge at the center (GC) of the glove, as previously discussed.

[0616] When the % L test range of tp on one side of the angle ruler is different from that on the other side, for example, tp on one side is in the range of >=75% L to <=100% L, while tp on the other side is in the range of >=50% L to <75% L, the angle ruler test rules for each side should be followed, and the test results of both sides will be used to determine the triangle shape.

[0617] To test the finger sleeves in a non-rotationally symmetric SHWT glove, the angle of the angle gauge is set based on the angle between the clamping radii (RC) of each finger sleeve in the SHWT glove. For example, refer to... Figure 24 F, in a non-rotationally symmetric SHWT glove b...
