Description

[Technical field]

[0001] The present invention relates to a hand support capable of supporting the wearer's daily activities, and in particular to a hand support capable of improving the stability of the thumb and / or wrist and reducing the burden on the thumb and / or wrist. [Background technology]

[0002] The thumb plays an important role in daily life, as it is involved in hand movements such as pinching objects, swinging a frying pan from side to side, holding chopsticks, turning doorknobs, carrying luggage, and holding onto train straps. In recent years, there has been an increase in cases of pain or discomfort in the thumb or wrist due to prolonged use of computers and smartphones, and the number of wrist and finger-specific disorders due to overuse has also increased.

[0003] Actions that overuse the range of motion of the wrist and fingers include bending the wrist toward the palm of the hand (palmar flexion), bending the wrist joint toward the thumb (radial side) (radial flexion), and bending the wrist joint toward the little finger (ulnar side) (ulnar flexion).

[0004] Overuse of the wrists and fingers makes it difficult to grasp or pinch objects, making it difficult to use the hands for long periods of time on a daily basis, resulting in interference with daily life.

[0005] Conventionally, to address this issue, strip-shaped taping tapes (elastic or non-elastic adhesive cloth tapes that are attached to parts of the body) or bandages or roughly cylindrical supports knitted with circular knitting have been used.

[0006] Of these, taping tape is not economical because it is disposable and has a high environmental impact. Furthermore, depending on the wearer's constitution, the adhesive in the taping tape may cause skin rashes, and elderly and other wearers with sensitive skin may suffer from epidermal peeling when the taping tape is removed.

[0007] For example, a conventional hand support includes a band-shaped main body portion woven from a fabric having a hook-and-loop surface and consisting of a wrapping portion that is wrapped around the wearer's wrist and a support portion that is positioned from the back or palm of the wearer's hand to the wrist, an anchor portion joined to one end of the main body portion through which the fingers of the wearer's hand are inserted, and an attachment portion joined to the other end of the main body portion and having a hook surface of a hook-and-loop fastener that can be attached and detached to the loop surface of the main body portion (see, for example, Patent Document 1).

[0008] Furthermore, for example, a conventional hand support is a wrist support that is worn on the wrist of a human body and includes a support base formed by integrally forming an elastically stretchable tubular wrist cover that covers at least a portion of the wrist and an elastically stretchable tubular thumb cover that covers at least a portion of the thumb of the human body, and a load application pattern portion formed by applying an elastic adhesive material made of a rubber material or an elastic resin material to the surface of the support base and having at least a thumb load application member portion that extends from the thumb cover to the wrist cover and is capable of applying a predetermined load (main load) to the movement of the thumb when the thumb is moved (see, for example, Patent Document 2).

[0009] Furthermore, for example, a conventional hand supporter includes a three-dimensional spiral supporter in which one of the ends of a single stretchable elastic band is twisted 360 degrees in a spiral shape and joined by sewing, welding, or the like, and then the appropriate locations where the elastic band crosses are joined by sewing, welding, or the like to form a three-dimensional figure-8 crossing with two circular portions (see, for example, Patent Document 3).

[0010] Also, for example, a conventional hand support is a wrist support that, although not for use in everyday life, is used to immobilize the wrist for learning spiking technique in volleyball spiking practice, and the wrist support has a pad that is arranged to cover the surface of the wrist + back side that extends from the back of the hand, over the back of the wrist, to the tip of the forearm, to which a finger belt for fastening the pad to the fingers and a strap belt for fastening the pad to the tip of the forearm are attached, and a rigid core material made of a rigid plate that prevents dorsiflexion of the wrist is enclosed between the outer surface of the pad and the lining on the skin side (see, for example, Patent Document 4). [Prior art documents] [Patent documents]

[0011] [Patent Document 1] International Publication No. 2015 / 133480 [Patent Document 2] JP 2022-20906 A [Patent Document 3] Utility Model Registration No. 3152361 [Patent Document 4] JP 2017-122287 A Summary of the Invention [Problem to be solved by the invention]

[0012] However, conventional hand supports, such as those described in Patent Documents 1 and 3, are composed of a single band, and due to their simple structure, they only have enough strength to tighten the band, and it is difficult to achieve a strength sufficient to fix the thumb while allowing freedom of movement.

[0013] There are conventional hand supports, such as that described in Patent Document 4, which have a different band-like structure. However, since this is designed for volleyball spike practice, it contains a rigid core material made of a rigid plate, which restricts freedom of movement in everyday use and cannot be used for everyday use.

[0014] Furthermore, in the case of devices such as those described in Patent Document 2, which apply a specified load to the movement of the thumb when the thumb is moved, the thumb is fixed with an elastic adhesive material, which requires the hand support to be considerably heavy as the specified load, making it difficult to provide a comfortable fit as a hand support, difficult to carry, and difficult to handle.

[0015] The present invention has been made to solve the above-mentioned problems, and has an object to provide a hand support that can stably fix the thumb and / or wrist while maintaining freedom of movement of the thumb and / or wrist, thereby reducing the burden on the thumb and / or wrist. [Means for solving the problem]

[0016] The hand support disclosed in the present application comprises a main body portion made of elastic fabric and having a thumb insertion portion through which the thumb of a wearer's hand is inserted to separate it from the other fingers, and a wrist insertion portion through which the wearer's wrist is inserted; a support portion formed from a first elastic band, one end of which is fixed within a region from the vicinity of the thumb insertion portion to the vicinity of the wrist insertion portion, and which is wrapped around the wearer's wrist and has the other end of the first band for releasably engaging with one side of the first band; and an auxiliary support portion formed from a second elastic band, one end of which is fixed at a position near the thumb insertion portion but different from the support portion, and which has a fabric opening formed by opening a hole in the middle of the fabric of the second band, and which has the wearer's thumb inserted through the fabric opening, and which has the other end of the second band for releasably engaging with one side of the first band.

[0017] In this way, the hand support disclosed in the present application comprises a main body portion made of elastic fabric and having a thumb insertion portion through which the thumb of the wearer's hand is inserted separately from the other fingers, and a wrist insertion portion through which the wearer's wrist is inserted; a support portion formed from a first elastic band, one end of which is fixed within a region from the vicinity of the thumb insertion portion to the vicinity of the wrist insertion portion, which is wrapped around the wearer's wrist and has the other end of the first band detachably attached to the first band; and a second elastic band, one end of which is fixed at a position near the thumb insertion portion but different from the support portion. The second belt is fixed at a position on the wrist, and a fabric opening is provided by opening the middle of the fabric of the second belt, and the wearer's thumb is inserted through the fabric opening, and the other end of the second belt is provided with an auxiliary support part that is detachably attached to the first belt. Therefore, the support part and the auxiliary support part are supported and fixed so as to firmly double-tighten and pressurize the thumb and wrist from positions close to each other with a simple configuration, and the support part fixes the wrist and fixes the left and right movement of the wrist, and the auxiliary support part suppresses excessive movement of the thumb and wrist, thereby reducing discomfort when the thumb and wrist are moved left and right. In addition, the movement of the brachioradialis muscle, which is the muscle that acts when bending the elbow and moving the palm up and down, is smoothed. In addition, the support part is formed of the elastic belt. As a result, the wearer can freely adjust the fixing force, and the wearer can obtain a comfortable feeling of pressure and wearing comfort.

[0018] In addition, the hand supporter disclosed in the present application may be one in which the support portion is fixed to the vicinity of the thumb insertion portion at one end of the first band-shaped body as required. In this manner, the support portion is fixed to the vicinity of the thumb insertion portion at one end of the first band-shaped body, and the support portion and the auxiliary support portion are supported and fixed to the thumb and wrist from positions adjacent to each other so as to firmly double-tighten and pressurize the thumb and wrist with a simple configuration, and the support portion fixes the wrist and fixes the left and right movement of the wrist, and the auxiliary support portion suppresses excessive movement of the thumb and wrist, thereby reducing discomfort when the thumb and wrist are moved left and right. In addition, the movement of the brachioradialis muscle, which is a muscle that acts when bending the elbow and moving the palm up and down, is made smoother. In addition, the support portion is formed of the elastic band-shaped body. As a result, the wearer can freely adjust the fixing force, and the wearer can obtain a comfortable feeling of pressure and wearing comfort.

[0019] In addition, the hand supporter disclosed in the present application may be one in which the support portion is fixed to the vicinity of the wrist insertion portion at one end of the first band-shaped body as required. In this manner, the support portion is fixed to the vicinity of the wrist insertion portion at one end of the first band-shaped body, and the support portion and the auxiliary support portion are supported and fixed so as to firmly double-tighten and pressurize the thumb and wrist from both sides of the thumb side and the wrist side, respectively, with a simple configuration, and the support portion firmly fixes the wrist from the vicinity of the wrist, more firmly fixing the left and right movement of the wrist, and the auxiliary support portion suppresses excessive movement of the thumb and wrist, thereby reducing discomfort when the thumb and wrist are moved left and right. In addition, the movement of the brachioradialis muscle, which is a muscle that acts when bending the elbow and moving the palm up and down, is smoothed. In addition, the support portion is formed of the elastic band-shaped body. As a result, the wearer can freely adjust the fixing force, and the wearer can obtain a comfortable feeling of pressure and wearing comfort.

[0020] In addition, the hand supporter disclosed in the present application is one in which one end of the second band of the auxiliary support part is fixed to the vicinity of the position opposite to the fixing position of the support part, sandwiching the thumb insertion part, as necessary. In this way, one end of the second band of the auxiliary support part is fixed to the vicinity of the position opposite to the fixing position of the support part, sandwiching the thumb insertion part, so that the support part and the auxiliary support part support and fix the thumb and wrist from the positions facing each other so as to simultaneously and firmly double-tightly pressurize them from both sides with a simple configuration, and the support part fixes the wrist and fixes the left and right movement of the wrist, and the auxiliary support part suppresses excessive movement of the thumb and wrist, thereby reducing discomfort when the thumb and wrist are moved left and right. In addition, the movement of the brachioradialis muscle, which is a muscle that acts when bending the elbow and moving the palm up and down, is smoothed. In addition, this support part is formed of the elastic band. This allows the wearer to freely adjust the fixing force, providing a comfortable feeling of pressure and fit.

[0021] In the hand support disclosed in the present application, the main body includes, as necessary, an other finger insertion portion through which the other finger of the wearer's hand is inserted and a wrist insertion portion through which the wearer's wrist is inserted. Since the main body includes an other finger insertion portion through which the other finger of the wearer's hand is inserted and a wrist insertion portion through which the wearer's wrist is inserted, the hand support can be stably positioned from the wearer's wrist when worn, and in conjunction with this, the positioning of the wearer's thumb and other finger can also be stabilized, resulting in a more comfortable fit for the wearer.

[0022] In the hand support disclosed in the present application, one end of the second band constituting the auxiliary support part is fixed to a portion corresponding to the ridge of the wearer's first interdigital space, as necessary. In this way, since one end of the second band constituting the auxiliary support part is fixed to a portion corresponding to the ridge of the wearer's first interdigital space, the auxiliary support part can be fixed in a position that is easy to fix the thumb along the direction toward the wrist, and the thumb and / or wrist joint can be pressed and fixed.

[0023] In the hand supporter disclosed in the present application, the support part has a loop surface of a hook-and-loop fastener on one side of the first belt and a hook surface of the hook-and-loop fastener on the other end of the first belt, and the auxiliary support part has a hook surface of the hook-and-loop fastener on the other end of the second belt, as necessary. In this way, the support part has a loop surface of a hook-and-loop fastener on one side of the first belt and a hook surface of the hook-and-loop fastener on the other end of the first belt, and the auxiliary support part has a hook surface of the hook-and-loop fastener on the other end of the second belt, so that the auxiliary support part and the support part can be engaged with each other on the hook surface and loop surface of the hook-and-loop fastener, and the wearer can freely adjust the fixing force by himself with a simple configuration. In addition, a comfortable wearing feeling and wearing strength are obtained for the wearer.

[0024] The hand support disclosed in the present application is composed, as necessary, of a thumb positioning and support part, the main body being arranged in a region adjacent to the thumb insertion part, in a first elasticated region made of knitted elastic material having greater elasticity in a short direction perpendicular to the longitudinal direction than in a longitudinal direction from the wearer's wrist to the fingers, for positioning and supporting the wearer's thumb, and another finger positioning and support part, the main body being arranged around the first elasticated region, in a second elasticated region made of knitted elastic material having elasticity in both the longitudinal direction and the short direction, for positioning and supporting the other finger of the wearer.

[0025] In this way, the main body is composed of a thumb positioning and supporting part that is arranged in a first elastic region formed by knitting an elastic member having higher elasticity in a short direction perpendicular to the longitudinal direction than in a longitudinal direction from the wrist to the fingers of the wearer, and a second finger positioning and supporting part that is arranged around the first elastic region and knitted an elastic member having elasticity in both the longitudinal direction and the short direction, and positions and supports the wearer's other fingers. Since the main body is composed of two regions with different elasticity, the thumb is fixed in the longitudinal direction and can be flexibly moved in the short direction, and excessive movement of the thumb is suppressed, and discomfort when the thumb is moved from side to side can be reduced. In addition, the movement of the brachioradialis muscle, which is a muscle that acts when bending the elbow and moving the palm up and down, is smoothed.

[0026] In the hand support disclosed in the present application, the thumb positioning support part is knitted with one-way raschel knitting in one direction along the longitudinal direction and knitted with urethane thread or rubber thread along the transverse direction as necessary. In this way, since the thumb positioning support part is knitted with one-way raschel knitting in one direction along the longitudinal direction and knitted with urethane thread or rubber thread along the transverse direction, the thumb is fixed in the longitudinal direction and can be flexibly moved in the transverse direction with a simple configuration, and excessive movement of the thumb is suppressed, thereby reducing discomfort when moving the thumb from side to side and facilitating the movement of the brachioradialis muscle, which is a muscle that acts when bending the elbow and moving the palm up and down.

[0027] In the hand supporter disclosed in the present application, the maximum elongation in the lateral direction of the thumb positioning and supporting part is preferably greater than the maximum elongation in the longitudinal direction, as necessary. For example, the maximum elongation in the lateral direction is preferably 1.5 times or more, and more preferably 2 times or more, of the maximum elongation in the longitudinal direction. In this way, since the maximum elongation in the lateral direction of the thumb positioning and supporting part is 5 to 10 times the maximum elongation in the longitudinal direction, the thumb is fixed by a fabric that is difficult to stretch in the lateral direction, and can move flexibly by a fabric that is easy to stretch in the longitudinal direction, so that excessive movement of the thumb is suppressed, and discomfort when moving the thumb from side to side can be reduced, and the movement of the brachioradialis muscle is smoothed.

[0028] The hand supporter disclosed in the present application is a device that can be worn on either the left or right wrist of the wearer as needed. Since the device can be worn on either the left or right wrist of the wearer, it is easy to use for the wearer. In addition, the manufacturing process can be simplified, and manufacturing costs can be reduced. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] (First embodiment) A hand supporter according to a first embodiment of the present invention will be described below with reference to the above-mentioned Figs. 1 to 13.

[0031] As shown in FIG. 1, the hand support according to the first embodiment of the present application is made of a stretchable fabric, and is formed from a main body 1 having a thumb insertion section 11 through which the thumb of the wearer's hand is inserted separately from the other fingers, and a wrist insertion section 13 through which the wearer's wrist is inserted, and a first stretchable band-like body, one end of which (support section one end 2a) is fixed within the region from the vicinity of thumb insertion section 11 to the vicinity of wrist insertion section 13, and the other end of the first band-like body ... The glove is provided with a support part 2 which is removably attached to one side of the first band at one end, and an auxiliary support part 3 which is formed from a stretchable second band, one end of which is fixed at a position different from the support part 2 among the positions near the thumb insertion part 11, and in which a fabric aperture 33 is provided by opening a hole in the middle of the fabric of the second band, the wearer's thumb is inserted through this fabric aperture 33, and the other end of the second band is removably attached to one side of the first band.

[0032] Thumb insertion portion 11 disposed in main body 1 can have an opening shape formed in a cylindrical shape, and the opening width of the opening shape is not limited as long as it is large enough to allow the thumb to be inserted, but from the viewpoint of fixing the thumb, it is preferable that the opening width has a moderate feeling of tightness, and for example, the opening width can be about 2 to 3 cm.

[0033] The other fingers refer to the four fingers other than the thumb: the index finger, middle finger, ring finger, and little finger.

[0034] The other finger can be fixed in the main body 1 by providing the other finger insertion portion 12 formed in a cylindrical shape in the main body 1. The configuration of the other finger insertion portion 12 is not particularly limited, but may be, for example, a shape in which each of the four fingers constituting the other finger is inserted separately, a shape in which each of the three fingers constituting the other finger and one finger is inserted separately, or a shape in which each of the two fingers constituting the other finger are inserted separately. The other finger insertion portion 12 may be adjacent to the thumb insertion portion 11, or may be spaced a predetermined distance apart.

[0035] The wrist insertion section 13 has a cylindrical opening shape, and the wearer's hand is inserted through the wrist.

[0036] In this way, the main body is provided with finger insertion section 12 through which the other finger of the wearer's hand is inserted, and wrist insertion section 13 through which the wearer's wrist is inserted, so that the glove can be stably positioned from the wearer's wrist when worn. This also stabilizes the positioning of the thumb and other fingers, providing a comfortable fit for the wearer.

[0037] This support part 2 is fixed to the main body part 1 at one end, that is, support part one end 2a, of this support part 2, and is composed of a support main body part 21 as the fabric main body of the first belt-like body having elasticity, and a support attachment part 22 arranged at the other end, that is, support part other end 2b, of this support part 2.

[0038] Since this support part 2 is made of a stretchy strip-shaped fabric, it easily conforms to the wearer's hand and the wearer can adjust the fixing force while wrapping it around the wearer. This does not apply excessive force to the movement of the wearer's wrist, provides stable fixing force, and is economical because it can be used repeatedly.

[0039] The position of the support part 2 is not particularly limited as long as one end 2a of the support part, which is one end of the first band, is fixed within the region from the vicinity of the thumb insertion part 11 of the main body part 1 to the vicinity of the wrist insertion part 13, and for example, as shown in Fig. 1, it can be disposed on the extensor pollicis longus side of the thumb, which is in the vicinity of the thumb insertion part 11 of the main body part 1. In other words, it can be disposed in the vicinity of a position of the thumb insertion part 11 that faces the first interdigital space with the wearer's thumb sandwiched between them.

[0040] The length of this support part 2 must be long enough to support the back or palm of the wearer's hand, and long enough to go around the wearer's wrist at least once to protect the wrist. There are individual differences in hand size depending on gender, age, etc., and there are no particular limitations, but it is suitable to set the length to, for example, 30 cm to 50 cm, preferably 40 cm to 50 cm.

[0041] The width of the support part 2 is not particularly limited, but may be, for example, 2 cm to 5 cm, and preferably 3 to 4 cm.

[0042] The thickness of this support part 2 is not particularly limited, but if it is too thick, it will be bulky and difficult to wrap around the wearer's wrist, and if it is too thin, the fabric itself will tend to bend easily and it will be difficult to obtain the desired fixing force, so for example, if the maximum elongation in the warp direction of this support part 2 is 60%, it is preferable to make the thickness 3 mm or less.

[0043] On the other hand, as shown in Figure 1 (b), the auxiliary support part 3 is composed of an auxiliary support main body part 31 which is the fabric main body of the second belt-shaped body having elasticity, a fabric opening part 33 formed by opening a hole in the middle of the fabric of the auxiliary support main body part 31, and an auxiliary support attachment part 32 arranged at the other end of the auxiliary support part 3 (other end 3b of the auxiliary support part).

[0044] In addition, as shown in FIG. 1(b), the fabric opening 33 is formed by opening the center of the fabric of the auxiliary support main body 31 along the longitudinal direction, and the shape thereof is not particularly limited as long as the center of the fabric of the auxiliary support main body 31 is penetrated.

[0045] The opening shape of the fabric opening 33 may be in an open state or in a closed state in a natural placement. In either case, the wearer's thumb can be inserted. The opening shape in the open state in a natural placement may be a circle or an ellipse. An example of an opening that is in a closed state in a natural placement is a slit shape. A slit shape is preferable because of its simple configuration and ease of manufacture.

[0046] The fabric opening 33 penetrates the center of the fabric of the auxiliary support main body 31, dividing the fabric into left and right halves, forming one divided portion 31a and another divided portion 31b.

[0047] The position of the auxiliary support part 3 is not particularly limited as long as one end 3a of the auxiliary support part 3 is fixed in the vicinity of the thumb insertion part 11, but it is preferably fixed near a position opposite to the fixed position of the support part 2 across the thumb insertion part 11. For example, as shown in Fig. 2, it is preferably fixed to part A corresponding to the ridge of the wearer's first interdigital space, which is near a position opposite to the fixed position of the support part 2 across the thumb insertion part 11.

[0048] The first interdigital space refers to the space between the thumb and index finger. The interdigital webbing of this first interdigital space corresponds to the part formed by the thin skin stretched in the interdigital space between the thumb and index finger. The ridge of this first interdigital space corresponds to the outline of this interdigital webbing.

[0049] The fastening method is not particularly limited, but for example, suturing can be used, and a straight suture line that follows the ridge of the wearer's first interdigital space allows for simple and strong fixation.

[0050] There are various types of stitching, including flat seam (four-needle stitching), overlock, and three-point staggered stitching. Flat seam stitching is preferred because it has the following advantages: the seams are thin, the force that holds the seams down produces flat and strong stitches, the mountain-shaped cut makes it easy to conform to three-dimensional shapes, and there is no seam allowance on the back of the fabric, so the stitching does not touch the skin and is comfortable to wear.

[0051] In particular, with regard to this fastening, it is preferable to overlap one divided portion 31a and the other divided portion 31b, which are the left and right fabric portions created by dividing the fabric of the auxiliary support main body portion 31 in the center by the fabric opening portion 33, facing each other as shown in Figure 3(a), and then fasten one end of this auxiliary support portion 3 (auxiliary support portion one end 3a) to portion A corresponding to the ridge of the wearer's first interdigital space described above, as shown in Figure 3(b).

[0052] With this configuration, by moving the auxiliary support part 3 in the direction toward the wrist, the thumb in the direction of the wrist can be fixed in a position that is easy to fix, and it can easily engage with the support part 2 in the direction of the wrist, so that the thumb and / or wrist joint can be pressurized and fixed.

[0053] 4, the auxiliary support part 3 has an appearance where one divided part 31a and the other divided part 31b overlap with each other at one end (auxiliary support part one end 3a) of the auxiliary support part 3, and has an appearance where one divided part 31a and the other divided part 31b gradually separate and expand toward the auxiliary support part other end 3b, forming a bulging appearance. That is, the auxiliary support part 3 has a shape equivalent to the lower side of the shape of the English letter Y at the auxiliary support part one end 3a side and a shape equivalent to the upper side of the shape of the English letter Y at the auxiliary support part other end 3b side, like the shape of the English letter Y, and therefore has an overall Y-shape, which can also be called a Y-shaped taping belt.

[0054] There is no particular limitation on the attachment of the support part 2 and the auxiliary support part 3, but as shown in Fig. 5(a), it is preferable that the support part 2 has a loop surface L of a hook-and-loop fastener on one side of the support main body part 21 and a hook F1 surface of a hook-and-loop fastener on the other end (support part other end 2b) of the support part 2. Although there is no particular limitation, by having the hook F1 surface on the back side of the loop surface L, attachment during attachment and detachment is facilitated.

[0055] By using the hook-and-loop fastener, the support part 2 and the auxiliary support part 3 can be repeatedly attached and detached, and their high flexibility provides a comfortable fit and ease of use, while the strong engagement force keeps the area around the thumb under pressure.

[0056] As shown in FIG. 5(b), it is preferable that the auxiliary support part 3 has a hook surface F2 of a hook-and-loop fastener at the other end of the auxiliary support main body part 31.

[0057] This allows the loop surface L of the hook-and-loop fastener arranged on one side of the support main body portion 21 to engage with the hook surface F1 of the hook-and-loop fastener arranged at the other end of the support main body portion 21, and also to engage with the hook surface F2 of the hook-and-loop fastener arranged at the other end of the auxiliary support main body portion 31 of the auxiliary support portion 3.

[0058] As shown in Figure 5(a), when the loop surface L of the hook-and-loop fastener arranged on one side of the support main body 21 is arranged on the surface (front surface) that becomes the outside when the support part 2 is wrapped around the wearer's wrist, it is preferable that the hook surface F2 of the hook-and-loop fastener arranged on the other end of the auxiliary support main body 31 of the auxiliary support part 3 be arranged on the back surface side of the other end of the auxiliary support main body 31 of the auxiliary support part 3 (the surface facing the thumb insertion part 11 of the main body 1) in terms of ease of attachment and removal and freedom of attachment position.

[0059] In this way, the support part 2 has a loop surface L of the hook-and-loop fastener on one side of the support main body part 21 and a hook surface F1 of the hook-and-loop fastener at the other end of the support main body part 21, and the auxiliary support part 3 has a hook surface F2 of the hook-and-loop fastener at the other end of the second belt-shaped body, so that the auxiliary support part 3 and the support part 2 can be attached to each other by the hook surfaces F1 and F2 and the loop surface L of the hook-and-loop fastener, and with this simple configuration, the wearer can freely adjust the fixing force, and the fixing force can be freely adjusted, resulting in a comfortable fit and strength for the wearer.

[0060] The positions at which support part 2 and auxiliary support part 3 are arranged are not particularly limited, but it is preferable that, as shown in FIG. 6(a), the end face of one end (support part one end 2a) of the first band of support part 2 be formed approximately perpendicular to the longitudinal direction Y toward the opening of thumb insertion part 11 along the perpendicular direction X, and it is also preferable that auxiliary support part 3 be arranged on the thumb insertion part 11 side (A1 side) of portion A corresponding to the ridge of the wearer's first interdigital space.

[0061] 6(b), it is preferable that the end face of one end of the first band (support portion one end 2a) be formed approximately perpendicularly along a direction X perpendicular to the longitudinal direction Y toward the opening of the thumb insertion portion 11. As a result, in the natural resting state, the support portion 2 is formed into a shape that extends along a reverse direction Y1 that is opposite to the traveling direction of the longitudinal direction Y of the thumb insertion portion 11, so that it can reach the wrist via the shortest route without any waste and can fix the wrist efficiently and firmly.

[0062] As shown in Fig. 6(c), it is preferable that the auxiliary support part 3 is disposed on the thumb insertion part 11 side (A1 side) of part A corresponding to the ridge of the wearer's first interdigital space, and more preferably, as shown in Fig. 6(c), the height of one end 3a of the auxiliary support part on the thumb insertion part 11 side (A1 side) is greater than the height of one end 2a of the support part 2 once fixed in a predetermined position by a height difference K, and even more preferably, it is disposed at a height that contacts the opening of the thumb insertion part 11 (thumb insertion opening 11a) where this height difference K is maximum. This allows the wearer's thumb to be passed through and fixed in place in the shortest possible route without waste, and the wearer's thumb can be fixed efficiently and firmly.

[0063] (How to wear) A method of wearing the hand supporter according to this embodiment will be described with reference to the above-mentioned Figs.

[0064] First, the wrist insertion part 13 is inserted through the wrist 130 of the wearer, and the main body part 1 is wrapped around the back and palm of the wearer's hand, and the thumb insertion part 11 is inserted through the thumb 110 of the wearer, and the other finger insertion part 12 is inserted through the other finger insertion part 12 of the wearer. As a result, as shown in Fig. 7(a), the main body part 1 is wrapped around the back and palm of the wearer's hand and worn in close contact, and the wearer's thumb 110 is exposed from the thumb insertion part 11, and the wearer's other finger 120 is exposed from the other finger insertion part 12. At this stage, the support part 2 and the auxiliary support part 3 are fully extended in a straight line and are not yet fixed, maintaining a belt-like shape.

[0065] 7(b), the support part 2 is wrapped around the wearer's wrist 130 in a wrapping direction B. This causes the support part 2 to be fixed to the wearer's wrist 130 while applying appropriate pressure to the wearer's wrist 130.

[0066] After wrapping the support part 2 around the wearer's wrist 130, as shown in Fig. 8(a), the support engagement part 22 is engaged and fixed to the front side (one side) of the support part 2 that has been wrapped around and fixed to the wearer's wrist 130. As a result, the wearer's wrist 130 is spirally taped by the support part 2. As shown in Fig. 8(a), after the wrist is fixed by the support part 2, the auxiliary support part 3 is moved so as to tilt in a direction C toward the wearer's thumb 110.

[0067] 8(b), the wearer's thumb 110 is inserted through the fabric opening 33 of the auxiliary support part 3. Since the auxiliary support part 3 has the shape of the Y-shaped taping belt described above, the wearer's thumb 110 can be easily inserted through the fabric opening 33, and the wearer's thumb 110 is enclosed by the one divided part 31a and the other divided part 31b, so that the wearer's thumb 110 is fixed.

[0068] Next, as shown in FIG. 8(b), the auxiliary support part 3 is moved in a direction D toward the wrist 130 of the wearer.

[0069] As a result, as shown in Figure 9, the auxiliary support attachment portion 32 at the other end (other end 3b of the auxiliary support portion) of the auxiliary support portion 3 engages and is fixed to the front side (one side side) of the support portion 2 which is wrapped around the wearer's wrist 130 and fixed.

[0070] As shown in FIG. 9, the auxiliary support part 3 having the shape of the Y-shaped taping belt described above wraps around the wearer's thumb 110 from both sides using the two divided pieces of fabric, one divided part 31a and the other divided part 31b, and the auxiliary support attachment part 32 at its tip is detachably attached to one side of the support part 2 in the opposite position, thereby wrapping and securing the thumb in a surrounding manner.

[0071] That is, the wearer's wrist 130 is spirally taped by the support part 2, and the wearer's thumb 110 is taped by being pinched in a Y shape by the auxiliary support part 3, thereby preventing the thumb from bending obliquely.

[0072] In this way, the hand support of this embodiment has a simple structure in which the support part 2 and auxiliary support part 3 firmly support and fix the thumb and wrist from near the positions where they face each other, and the support part 2 and auxiliary support part 3 support and fix the thumb and wrist from near the positions where they face each other by firmly tightening and pressurizing them with a simple structure, so that the support part 2 fixes the wrist and fixes the left and right movement of the wrist, and the auxiliary support part 3 suppresses excessive movement of the thumb and wrist, thereby fixing the left and right movement of the wrist joint, reducing discomfort when moving the thumb or wrist from side to side and facilitating the movement of the brachioradialis muscle.

[0073] The brachioradialis muscle is a muscle located from the elbow to the wrist that works when bending the elbow and moving the palm up and down, and also works to flex the elbow joint and rotate the forearm in a semi-pronated position.

[0074] In addition, the support part 2 formed of this band-shaped body allows the wearer to freely adjust the fixing force according to, for example, the thickness of the wrist or the desired pressure feeling, and provides a comfortable pressure feeling and wearing comfort. As a result, the hand supporter according to this embodiment can suppress symptoms that make it difficult for the wearer to grasp or pick up objects. In addition, it is easy to wear and easy to use, making it possible to use it daily for long periods of time. In addition, it meets the need to wear it inconspicuously.

[0075] In the above, the hand supporter according to this embodiment has a preferred configuration in which the support part 2 is fixed near the thumb insertion part 11, but this configuration is not limited to this, and as long as one end of the first band (support part end 2a) is fixed within the area from the vicinity of the thumb insertion part 11 to the vicinity of the wrist insertion part 13, it is not limited to this configuration.

[0076] For example, as shown in FIG. 10(a), the position of the support part 2 can be arranged near the wrist insertion part 13, different from the above. In this case, the support part 2 and the auxiliary support part 3 are supported and fixed so as to firmly double-tighten and pressurize the thumb and wrist of the wearer from both sides of the thumb side and the wrist side, respectively, with a simple configuration, and in particular, the support part 2 firmly fixes the wrist from the vicinity of the wrist, more firmly fixing the left and right movement of the wrist, and the auxiliary support part 3 suppresses excessive movement of the thumb and wrist, so that discomfort when moving the thumb and wrist left and right can be reduced. In addition, the movement of the brachioradialis muscle, which is a muscle that acts when bending the elbow and moving the palm up and down, is smoothed, and a comfortable feeling of pressure and wearing can be obtained for the wearer. In addition, as will be described later, when a first stretchable region G is arranged as in FIG. 14 of the second embodiment, it is more preferable that the support part one end 2a of the support part 22 is arranged in the first stretchable region G. Combined with the low elasticity in the direction of the thumb provided by this first elastic region G, the strength with which this support section 22 is fixed to the thumb can be further increased.

[0077] In addition, as shown in FIG. 10(b), the support section 22 may be arranged closer to the thumb insertion section 11 than the wrist insertion section 13. In this case, the support section 22 is supported and fixed so that the support section 2 and the auxiliary support section 3 are further supported and fixed by a simple structure so that the thumb and wrist are tightly double-tightened and pressurized from positions close to each other, and the support section 2 fixes the wrist and fixes the left and right movement of the wrist, while the auxiliary support section 3 suppresses excessive movement of the thumb and wrist, thereby reducing discomfort when the thumb and wrist are moved left and right. In addition, the movement of the brachioradialis muscle is smoothed, and a comfortable feeling of pressure and wearing can be obtained for the wearer. In addition, as will be described later, when the first stretchable region G is arranged as in FIG. 14 of the second embodiment, it is more preferable that the support section one end 2a of the support section 22 is arranged in the first stretchable region G. Combined with the low elasticity in the direction of the thumb provided by this first elastic region G, the strength with which this support section 22 is fixed to the thumb can be further increased.

[0078] In the above, the hand supporter of this embodiment is configured so that the auxiliary support part 3 is fixed to part A corresponding to the ridge of the wearer's first interdigital space, but this configuration is not limited to this, and as long as one end of the auxiliary support main body part 31 (auxiliary support part one end 3a) is fixed in the vicinity of the thumb insertion part 11, it is not limited to this configuration.

[0079] For example, as shown in FIG. 11, the auxiliary support part 3 can be disposed at a position different from the above, on the extensor pollicis longus side of the wearer's thumb. In this case, the support part 2 can be disposed at the position of the first interdigital space of the wearer, near the position facing the auxiliary support part 3. In this case, as in the above, the left and right movement of the wearer's wrist joint can be fixed, and discomfort when the thumb or wrist is moved left and right can be reduced. In addition, the movement of the brachioradialis muscle is smoothed. Furthermore, the support part 2 formed of a band-shaped body allows the fixing force to be freely adjusted according to the wearer, and a comfortable wearing feeling can be obtained.

[0080] In addition, auxiliary support part 3 is not particularly limited as long as it is fixed near a different position of thumb insertion part 11 from that of support part 2 among positions in the vicinity of thumb insertion part 11 .

[0081] For example, as shown in FIG. 12, the support part 2 is arranged on the palm or back of the hand so as to be formed along the longitudinal direction toward the wrist via the palm or back of the hand, and the auxiliary support part 3 can be formed on the extensor pollicis longus side of the thumb at a position facing the support part 2 at approximately 90 degrees across the thumb insertion part 11.

[0082] In addition, as shown in FIG. 13, the support part 2 can be formed on the extensor pollicis longus side of the thumb, and the auxiliary support part 3 can be arranged on the palm or back of the hand at a position facing the support part 2 at approximately 90 degrees across the thumb insertion part 11, so that the support part 2 can be formed in the longitudinal direction toward the wrist via the palm or back of the hand.

[0083] In addition, the vicinity of the opening of thumb insertion section 11 may be made of a different stretchable fabric. This configuration allows the thumb, which is frequently put on and taken off, to be more firmly secured in place.

[0084] Second Embodiment In the second embodiment of the present application, similar to the hand support according to the first embodiment described above, it comprises a main body portion 1, a support portion 2, and an auxiliary support portion 3, and further, the main body portion 1 is composed of two parts with different elasticity.

[0085] That is, as shown in FIG. 14, the second embodiment of the present application is configured such that the main body 1 is arranged in a region adjacent to the thumb insertion portion 11, in a first stretchable region G made of knitted stretchable material having higher stretchability in a short direction perpendicular to the longitudinal direction than in a longitudinal direction from the wearer's wrist to the fingers, and includes a thumb positioning and supporting portion 21a for positioning and supporting the wearer's thumb, and another finger positioning and supporting portion 21b for positioning and supporting the other finger of the wearer, in a second stretchable region H arranged around the first stretchable region G and made of knitted stretchable material having stretchability in both the longitudinal direction and the short direction.

[0086] The first stretchable region G in which the thumb positioning support portion 21a is disposed is not particularly limited as long as it is disposed in the region adjacent to the thumb insertion portion 11, but it is preferable that it be formed in a region that accommodates the ball of the foot, which is the bulging part at the base of the wearer's thumb, as shown in FIG. 15.

[0087] This thumb positioning support portion 21a allows the wearer's thumb to be inserted therethrough, thereby positioning the main body portion 1 relative to the wearer's wrist, and also suppresses rotational movement of the main body portion 1 in the winding direction relative to the wearer's wrist, thereby preventing misalignment.

[0088] As long as the thumb positioning support portion 21a is disposed in the area adjacent to the thumb insertion portion 11, it is shaped to reach the other finger insertion portion 12 in the first inter-finger space of the wearer as described above, but is not limited thereto, and for example, as shown in Fig. 16, it may be shaped to reach the middle between the thumb insertion portion 11 and the other finger insertion portion 12 in the first inter-finger space of the wearer without reaching the other finger insertion portion 12 in the first inter-finger space of the wearer. Also, as shown in Fig. 17, for example, it may be shaped to extend in a straight line from the vicinity of the opening of the thumb insertion portion 11 to the wrist side in the first inter-finger space of the wearer without reaching the other finger insertion portion 12 in the first inter-finger space of the wearer.

[0089] The first stretchable region G in which the thumb positioning support portion 21a is arranged is formed by knitting a stretchable material that has higher stretchability in the short direction (course direction J) perpendicular to the longitudinal direction from the wearer's wrist to the fingers (wale direction I) than in the longitudinal direction, as shown in Figure 18(a).

[0090] Such an elastic member can be, for example, a narrow-width elastic fabric woven by combining warp and weft threads on a power loom such as a needle loom or a jacquard needle loom, and which has elasticity in the short direction (course direction J) and reduced elasticity in the long direction (wale direction I).

[0091] For example, it is preferable that the thumb positioning support portion 21a is knitted with a unidirectional one-way raschel knitting method that exhibits elasticity only along one direction of the short side (course direction J), and further it is preferable that the thumb positioning support portion 21a is knitted with urethane yarn or rubber yarn along the short side (course direction J).

[0092] This unidirectional one-way raschel knitting is a knitted fabric knitted using a raschel knitting machine, and is a knitting method that can be configured to have a low elongation rate in only one of the longitudinal direction (wale direction I) or lateral direction (course direction J). In this embodiment, it is possible to create elasticity in only one direction, the lateral direction (course direction J).

[0093] The urethane yarn may be, for example, a polyurethane yarn. For example, a polyurethane yarn having a thickness of 800 to 900 denier may be used, and a yarn in which a polyurethane yarn is covered with a nylon yarn may also be used. The rubber yarn is not particularly limited, but a covered yarn having a thickness of 60 to 130 may be used.

[0094] This knitting results in high stretchability in the short direction (course direction J) and almost no stretchability in the long direction (wale direction I), resulting in anisotropic stretchability characteristics.

[0095] In this way, the thumb positioning support portion 21a is knitted with unidirectional one-way raschel knitting along the longitudinal direction and with urethane or rubber yarn along the transverse direction, so that with a simple configuration, the thumb is fixed in the longitudinal direction while allowing flexible movement in the transverse direction, thereby suppressing excessive movement of the thumb, reducing discomfort when moving the thumb from side to side, and facilitating the movement of the brachioradialis muscle.

[0096] The elasticity of the elastic material constituting this first elastic region G is not particularly limited, but it is more preferable that the maximum elongation in the short direction (course direction J) is 1.5 times or more, and preferably 2 times or more, of the maximum elongation in the long direction (wale direction I).

[0097] Due to this correlation of maximum elongation, as shown in Figure 18(b), the anisotropic stretchability property is more strongly exhibited, in which there is almost no stretch in the longitudinal direction (wale direction I) but essentially stretches in the transverse direction (course direction J).

[0098] Since the maximum elongation in the short direction of this first stretchable region G is at least 1.5 times, and preferably at least twice, the maximum elongation in the long direction, the thumb is fixed in place by fabric that does not stretch easily in the long direction, while at the same time allowing flexible movement by fabric that stretches easily in the short direction. This suppresses excessive movement of the thumb, reduces discomfort when moving the thumb from side to side, and facilitates the movement of the brachioradialis muscle.

[0099] In addition, while maintaining the flexibility of the thumb positioning support portion 21a, its tightening force fixes the wearer's wrist joint, improving the stability of the wrist joint, thereby reducing the burden on the wrist joint during the wearer's daily activities.

[0100] On the other hand, as for the other finger positioning and supporting part 21b which positions and supports the other finger of the wearer, a mesh fabric having a large number of ventilation holes on the surface of the fabric is suitable as the knitted elastic member, and although a nylon material can be used, it is particularly suitable to use a mesh fabric using polyurethane elastic yarn, that is, a so-called power net fabric.

[0101] Power net fabric is a finely woven mesh fabric with high elasticity, which provides high elasticity and resilience, as well as excellent breathability, water absorption, and quick drying, making it comfortable to wear for long periods of time.

[0102] As shown in FIG. 19, the hand supporter according to this embodiment can be worn on the wearer's hand in the same manner as in FIGS. 7 to 9 of the first embodiment.

[0103] In this way, by having main body 1 composed of two areas with different elasticity, the thumb is fixed in the longitudinal direction while being able to move flexibly in the lateral direction, thereby suppressing excessive movement of the thumb, reducing discomfort when moving the thumb from side to side, and facilitating the movement of the brachioradialis muscle, which is active when bending the elbow or turning the palm up and down.

[0104] (Other embodiments) Furthermore, since the hand support according to each of the above embodiments is constructed with a simple shape, it can be used on either the left or right wrist of the wearer.

[0105] For example, the circumference of the back of the hand of a wearer wearing the hand support according to each of the above embodiments can be designed to be 17 to 21 cm. This circumference of the back of the hand is based on statistical information on the volume zone of hand widths of Japanese people (for example, the AIST body size database, etc.), and can be used on both the left and right hand, as well as both men and women. This means that the hand support as a product requires only one SKU (Stock Keeping Unit) for inventory management, which is common to both left and right hands.

[0106] As such, the device can be worn on either the left or right wrist of the wearer, making it easy for the wearer to handle, simplifying the manufacturing process, improving usability, and reducing manufacturing costs and inventory management costs. [Explanation of symbols]
