[0001] <Cross-Reference to Related Applications> This application claims the priority benefit of U.S. Patent Application No. 18 / 776,096, entitled "Strap Devices, Systems, and Methods for Sports Equipment," filed on July 17, 2024, which is a divisional application of U.S. Patent Application No. 18 / 407,261, entitled "Strap Devices, Systems, and Methods for Sports Equipment," filed on January 8, 2024, which claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Application No. 63 / 517,564, entitled "Strap Devices, Systems, and Methods for Sports Equipment," filed on August 3, 2023, the disclosure of which is hereby incorporated by reference in its entirety.

[0002] The present disclosure relates to devices, systems, methods, and assemblies for holding sports equipment such as baseball or softball bats and maintaining contact between the equipment and both hands through a batting motion, a swinging motion, or an attempted swinging motion. While certain aspects and features of the present disclosure are described herein with reference to baseball or softball, the scope of the present disclosure is not limited to the field of baseball or softball and may include other sports or activities. For example, the present disclosure may be used in tennis, cricket, badminton, pickleball, golf, lacrosse, field hockey, ice hockey, table tennis, or any other sport that requires both hands of a user to remain engaged in the follow-through motion during a swinging motion, an attempted swinging motion, or after contact with another object such as a ball.

Background Art

[0003] Sports equipment and accessories include a variety of items used in or around a particular sport, such as during the preparation phase, training sessions, actual matches, or competitive events. Some sports accessories (e.g., baseball bats, tennis rackets, golf clubs) are necessary for athletes (or general users) to play a particular sport. Other accessories can protect the user during sports and / or help improve the user's performance. For example, helmets can protect an athlete's head, and gloves can protect a baseball player's hands (and / or help them grip the bat more securely). However, while gloves protect the skin on a baseball player's hands, the player is still vulnerable to injuries that may occur during the swinging motion, swing attempts, or follow-through after actually hitting the ball.

[0004] This disclosure recognizes the problems with swing motions currently practiced in sports, and provides solutions to address problems that users may encounter during the follow-through motion when swinging, attempting to swing, or actually hitting a ball using sports equipment. [Overview of the Initiative] [Problems that the invention aims to solve]

[0005] One concern concerns user performance when using sports equipment to hit or attempt to hit a ball (or other object), or during and / or after swinging (or attempting to swing) sports equipment. For example, during a baseball game, a batter holding a baseball bat would want to hold the bat with both hands and maintain contact with it before swinging or attempting to hit the ball, during the swing motion, after actually hitting the ball, and until the hitting or swing motion is complete. This swing or hitting motion may be roughly similar to a semicircular motion. The ability to hold both hands on the bat throughout the entire motion allows the user to maintain better control and / or increase swing speed, thereby allowing the ball to travel faster and further. The device of this disclosure can address this concern. For example, by simulating a locking motion that encourages the use of both hands, the device of this disclosure can achieve increased power during the swing. Furthermore, the device of this disclosure may contribute to increasing the power that the user can generate by encouraging the user to bring the upper hand closer to the lower hand and / or the grip of the bat, thereby generating a greater moment. The device of this disclosure may enable the user to improve the power that the user can generate by matching the speed of the front or lower hand with the back or upper hand, while maintaining a unified state and using leg power when making contact with the ball.

[0006] Another concern concerns the user's health and safety during the follow-through motion. For example, during a baseball game, if the second hand loses contact with the bat after the user has swung, attempted to swing, or actually hit the ball, uncontrolled movement of the first hand / arm / shoulder could result in injury to the first hand / arm / shoulder that is maintaining contact with the bat. The device of this disclosure can provide a solution to this concern. For example, by allowing the user to retain both hands on the bat after swinging or attempting to swing, the device of this disclosure can reduce the forces acting on the user's body during the swing motion.

[0007] Another concern concerns the health and safety of people around the user after an uncontrolled follow-through. For example, during a baseball game (or practice), an uncontrolled (usually one-handed) follow-through after a user attempts to hit the ball, or actually hits the ball, could injure the catcher, umpire, or other people nearby. The device of this disclosure can provide a solution to this concern. For example, by shortening the backswing and the corresponding follow-through, the likelihood of the follow-through injuring people around the batter can be reduced.

[0008] Another concern concerns the applicability of devices or methods that assist in maintaining follow-through motion. For example, a device that works with a specific piece of sports equipment may not be suitable for many users who prefer different types of sports equipment. Similarly, a device that works with a specific brand of batting gloves may not be suitable for users who prefer different brands. The devices disclosed herein are compatible with a wide variety of different brands and types of equipment.

[0009] Another concern concerns how users can maintain contact with sports equipment with both hands and how they can quickly switch between different accessories. For example, during a baseball game, a user may want to quickly release the baseball bat. Devices that fix both hands, or devices that fix one hand (or both hands) to the bat, may be unsuitable. The device of this disclosure addresses this concern by allowing the user to quickly release the bat without fixing their hands to it.

[0010] Another concern concerns the durability of devices that assist in follow-through motion or control of such motion. For example, certain sports are performed outdoors, and devices may be exposed to adverse weather conditions. The devices of this disclosure may include durable materials that can withstand adverse weather conditions and be used in a variety of weather conditions. [Means for solving the problem]

In some aspects, the strip 55 may be bent to form a loop portion 60. In some aspects, the strip 55 may include a lower grip portion 61 (also called the grip portion 61) and an upper grip portion 63. The grip portion 61 and the upper grip portion 63 may have elongated bodies. In some aspects, the strip 55 may have a wider loop portion 60 (or upper grip portion 63) than the lower grip portion 61. For example, the strip 55 may form a flared portion in the loop portion 60 and / or the lower grip portion 61. The length of the strip 55 may be any number or fraction of about 8 inches, or about 10 inches, or about 14 inches, or about 14.5 inches, or less than about 8 inches, or greater than about 14.5 inches. In light of the fact that the optimal length and width for maintaining a given hand position in a particular sporting instrument varies from application to application, those skilled in the art will understand that the devices disclosed herein may have dimensions that differ somewhat from those provided above to accommodate the grip requirements of a particular sport or sporting instrument. The strip 55 may have a first end 51 and a second end 52. The first end 51 may be located at one end of the strip 55.The second end 52 may be located at the opposite end of the strip 55.

[0089] The strip 55 may include a first side and a second side. In some embodiments, the strip 55 may include a first layer 56 and a second layer 57. The first layer 56 may be located on the first side (face) of the strip 55, and the second layer 57 may be located on the second side (face) of the strip 55. When in use, the first side (face) of the strip 55 may come into contact with the user's hand (or a hand covering device), and the second side (face) of the strip 55 may come into contact with sports equipment. In some aspects, the first layer 56 and the second layer 57 may be located directly opposite each other. The first layer 56 and the second layer 57 may be joined to each other by various means. In some aspects, the first layer 56 may be sewn to the second layer 57. In some aspects, the first layer 56 and the second layer 57 may be joined to each other with adhesive. The first layer 56 and the second layer 57 may be manufactured with a space (or gap) between them, but in different aspects of the strap device 50 of this disclosure, they can be manufactured with or without a space between the first layer 56 and the second layer 57. The thickness of the strip 55 may be constant or variable. Generally, the thickness of a particular layer can be selected depending on the desired final characteristics of the strip or on the user's needs (e.g., to provide strength while balancing the need for grip). For example, the thickness of the strip 55 may be about 0.5 mm, or about 1 mm, or about 1.2 mm, or about 1.5 mm, or about 1.75 mm, or about 2 mm, or about 2.5 mm, or any other thickness less than about 0.5 mm or greater than about 2.5 mm, depending on the user's needs. The thickness of the strip 55 will be the sum of the thicknesses of the first layer 56 and the second layer 57 and other additional layers, plus the space and / or gap between each layer. The first layer 56 and the second layer 57 can be manufactured from a variety of materials. For example, the first layer 56 and / or the second layer 57 may be made from leather, silicone, rubber, neoprene (polychloroprene), nylon, spandex, cotton, polyester, other fibrous materials, webbing, etc. In some aspects, the first layer 56 may include 1-inch wide nylon webbing.In some cases, the second layer 57 may include leather approximately 1.2 millimeters thick. In some cases, the leather is cowhide. As a result, the strip 55 may be manufactured to have rigid or flexible properties depending on the user's needs. In some cases, the strip 55 and / or other components of the strap device 50 may be supplied in roll form. The material used to manufacture the strip 55 may be selected to assist in stabilizing and securing the sports equipment when the user holds the sports equipment (for example, to provide grip and flexibility).

[0090] In some embodiments, the first layer 56 may include a thin material layer, and the second layer 57 may include a thick material layer. For example, the first layer may include a thin layer consisting of a thin layer of nylon webbing, and the second layer may include a thick layer consisting of a thick layer of leather. In some aspects, the second layer may not cover the entirety of the first layer, or vice versa. For example, the length of the second layer may be about 70% of the length of the first layer. In other aspects, the length of the second layer may be about 40%, or about 60%, or about 75%, or about 80%, or any number or fraction less than about 40% or greater than about 80%. In some other aspects, the length of the first layer may be about 70% of the length of the second layer. In some aspects, the length of the first layer may be about 75% or 80%, or any number or fraction less than 70% or greater than 80% of the length of the second layer. Other combinations of one or more material layers of different lengths can also be used to meet user needs. Therefore, the strip 55 may have a uniform or substantially uniform thickness along its entire length, or its thickness may vary throughout the length of the strip. In some aspects, the first layer 56 and the second layer 57 may have the same or similar widths. In some other aspects, the first layer 56 and the second layer 57 may have different widths so as not to overlap each other. The first layer 56 and the second layer 57 may each have a first face and a second face opposite to the first face. The strip 55 (and consequently each of the first layer 56 and the second layer 57) may have a first end and a second end opposite to the first end.

[0091] Continuing to refer to Figure 1, the strip 55 is foldable to form a loop portion 60 that can be configured to receive a user's hand. In some cases, the loop portion 60 can be formed by connecting a second end 52 to a loop end 62 positioned on the strip 55. The second end 52 can be connected to the loop end 62 by various means. For example, the second end 52 can be sewn, connected by a hook-and-loop Velcro® fastener system, or by any other acceptable mechanism. The loop end 62 can be positioned at various different locations along the strip 55 to accommodate the user's needs. For example, a user with larger hands may require a larger loop. In some cases, the closer the loop end 62 is to the first end 51, the larger the loop portion 60 can be. In some cases, when the second end 52 is connected to the first layer 56 at the loop end 62, the strap device 50 can form a shape roughly resembling the number 9. In some configurations, the second end 52 may contact the strip 55 at the loop end 62, extend along the entire length of the first end 51, or contact it at any point between them. For example, in some configurations, the second end 52 may bend and be joined to the first end 51 such that the first layer 56 of the first end 51 contacts the first layer 56 of the second end 52. The first end 51 and the second end 52 may overlap to form a grip length D1 (as shown in Figure 4). The grip length D1 may correspond to the length of the grip portion 61. The grip length D1 may correspond to the length between the first end 51 and the loop end 62. In some configurations, the grip length D1 includes the first layer 56. In some other configurations, the grip length D1 includes the first layer 56 which is positioned to fold back relative to the first layer 56 at the first end to form a double-layer overlap. For example, if the first layer 56 includes nylon and the second layer 57 includes leather, the grip portion 61 may include the two layers of nylon and at least one layer of leather along the first end and / or grip length D1.

[0092] Continuing to refer to Figure 1, in some aspects the strap device 50 may include a first strip attachment portion 58 located at the first end 51. In some aspects the first strip attachment portion 58 may be coupled (or fitted) to a second strip attachment portion 59. In some aspects the first strip attachment portion 58 and the second strip attachment portion 59 may form a hook-and-loop Velcro® fastener system. This configuration allows the user to more securely fasten and hold the grip portion 61 of the strap device 50 to the first hand cover 70. In some other aspects the first strip attachment portion 58 and the second strip attachment portion 59 may form a hook-and-loop Velcro® fastener system, so that when the first strip attachment portion 58 and the second strip attachment portion 59 are coupled, the strap device 50 may have a generally circular overall shape, as shown in Figure 2. This configuration has the advantage of making the overall space occupied by the strap device 50 compact when it is not in use. In some configurations, the first strip mounting portion 58 may be located at the first end, and the second strip mounting portion may be located at the loop portion 60. In some configurations, the first strip mounting portion 58 may be located at the first end 51, and the second strip mounting portion may be located at the second hand cover 80 (details below).

[0093] Figure 2 is a perspective view showing the strap device 50 of Figure 1 in a closed position in one plane. In the closed position, the grip portion 61 and the loop portion 60 can be joined using the first strip attachment portion 58 and the second strip attachment portion 59. In the closed position, the strap device 50 can form an overall shape that is generally circular.

[0094] Figure 3 shows a side view of the strap device 50 in the open position. In the open position, the first strip attachment portion 58 and the grip portion 61 are positioned away from the loop portion 60 and the second strip attachment portion 59. As previously mentioned, the loop portion 60 can be formed by joining the first layer 56 at the loop end 62. In some aspects, the loop end 62 can be configured to join the first layer 56 to the first layer 56. In other aspects, the loop end 62 can be configured to join the first layer 56 to both the first layer 56 and the second layer 57.

[0095] Figure 4 is a side view showing the strap device 50 in the open position. In the open position, the first strip attachment portion 58 and the grip portion 61 are located away from the loop portion 60 and the second strip attachment portion 59. The loop portion 60 can be formed by joining the first layer 56 at the loop end 62. In some aspects, the loop end 62 may be configured to join only the first layer 56. In other aspects, the first layer 56 may be joined to both the first layer 56 and the second layer 57. As previously mentioned, the first end 51 and the second end 52 can overlap to form a grip length D1. The grip length D1 may correspond to the length of the grip portion 61. The grip length D1 may correspond to the length between the first end 51 and the loop end 62. In some aspects, the grip length D1 includes the first layer 56 and the second layer 57. In some other aspects, the grip length D1 includes the first layer 56 which is folded back and positioned relative to the first layer 56 at the first end 51, forming an overlapping portion of the two layers. For example, if the first layer 56 includes nylon and the second layer 57 includes leather, the grip portion 61 may include two layers of nylon and one layer of leather along the first end 51 and / or the grip length D1.

[0096] Figure 5 shows a plan view of one aspect of a strap device 50 configured to be used (or manufactured) with a first hand cover 70 in an open position. In this aspect, the strip 55 is sewn at the loop end 62, and the first hand cover 70 passes through the resulting loop portion 60 (see Figure 6). As previously mentioned, in the open position, the first strip attachment portion 58 and the grip portion 61 are located away from the loop portion 60 and the second strip attachment portion 59. The grip length D1 is identified, which corresponds to the length between the first end 51 and the loop end 62. In some aspects, the first hand cover 70 can be a glove, such as a batting glove. In other aspects, other types of hand cover accessories used in different sports (e.g., golf gloves, cricket batting gloves, etc.) can be used with the strap device 50. The strap device 50 can be used with or without the first hand cover 70 or the second hand cover 80. For example, a user can pass their bare hand directly through the loop portion 60 without wearing any gloves.

[0097] Figure 6 is another plan view showing one aspect of a strap device 50 configured to be used (or manufactured) with a hand cover. It can be seen that the first hand cover 70 is positioned within the loop portion 60 (see Figure 1) of the strap device 50. As previously mentioned, the size of the loop portion 60 is adjustable, and the strap device 50 can be manufactured in different sizes to suit user needs. In some aspects, the size of the loop portion 60 can be adjusted by bringing the loop end 62 closer to the first end 51. In some aspects, the strip 55 is manufactured from a flexible material, and the size of the loop portion 60 can be adjusted when the user puts their first hand through the loop portion 60. The loop portion 60 may include an upper grip portion 63. When in use, the upper grip portion 63 can be sandwiched between the user's first hand (or first hand cover 70) and the sports equipment. As will be described later, the strap device 50 can be manufactured with or without the loop portion 60. For example, the grip portion 61 can be attached to the first hand cover 70 without requiring the loop portion 60.

[0098] Figure 7 shows one view of the strap device 50 in use. As can be seen from the figure, the user's first hand 170 is placed on the first hand cover 70, and the first hand cover 70 is placed on the loop portion 60. In one view, the position of the loop end 62 can correspond to the opening size of the loop portion 60. For example, the closer the loop end 62 is to the first end 51, the larger the opening size of the loop portion 60. A larger opening size of the loop portion 60 allows it to accommodate users with larger hands. As shown in Figure 7, the grip portion 61 is located away from the first hand cover 70, and the strap device 50 is in an open position.

[0099] Figure 8A shows one aspect of the strap device 50 in use with the assembly 100, which has the first hand cover 70 in a closed position, and Figure 8B shows one aspect of the strap device 50 in use with the first hand cover 70 in an open position. As can be seen in the closed position shown in Figure 8A, the grip portion 61 is coupled to the first hand cover 70. In some aspects, the first strip attachment portion 58 is engulfable with the second strip attachment portion 59, which facilitates the connection between the grip portion 61 and the first hand cover 70. On the other hand, in the open position shown in Figure 8B, the grip portion 61 is positioned away from the first hand cover 70.

[0100] Figure 9A shows one aspect of the strap device 250 used in a closed position with the first hand cover 270 in the assembly 200, and Figure 9B shows one aspect of the strap device 250 used in an open position with the first hand cover 270. In some aspects, the assembly 200 may be a wearable device. In some aspects, the assembly 200 may include a first hand restraint that can be configured to secure the user's first hand to the sports equipment using the user's second hand. As can be seen in the closed position shown in Figure 9A, the grip portion 261 is connected to the first hand cover 270. More specifically, the loop portion (similar to the loop portion 60) may be omitted, and the grip portion 261 can be directly connected to the first hand cover 270 at the loop end 262. In some aspects, the first strip attachment portion 258 engages with the second strip attachment portion 259 to facilitate coupling the grip portion 261 to the first hand cover 270 in a closed position. On the other hand, in the open position shown in Figure 9B, the grip portion 261 is positioned away from the first hand cover 270. In some embodiments, similar to the embodiment of the strap device 50 shown in Figure 1, the grip portion 261 may include a first layer 256 and a second layer 257.

[0101] In some cases, the strap device 50 can be manufactured as a standalone unit that can be used in combination with other sports equipment. For example, a user may obtain the strap device 50 separately and use it in combination with a pair of gloves from any manufacturer. In some other cases, the strap device 50 is sewn onto the first hand cover 70 at the factory. For example, when a user obtains a pair of gloves, the strap device 50 is already sewn onto the gloves (or attached by another mechanism).

[0102] Figures 10A and 10B show an assembly 100 including one aspect of a strap device 50 used with a first hand cover 70 and a sports equipment 90 in an open position. As shown in Figure 10A, the user 110's first hand 170 is positioned inside the first hand cover 70 and passed through the loop portion 60 of the first hand cover 70. The user can place the first hand cover 70 on the sports equipment 90 by passing it through the loop portion 60. In some aspects, the user 110 can use a second hand cover 80 to detach the grip portion 61 from the loop portion 60. The second hand 180 can be placed inside the second hand cover 80. The second hand cover 80 can be placed on the sports equipment 90 such that the second hand cover 80 presses the grip portion 61 against the sports equipment 90. This allows the user to use the second hand 180 to secure the first hand 170 to the sports equipment 90 throughout the swing motion. As shown in Figure 10B, in certain scenarios, the user can operate the strap device 50 using a bare hand, such as a first hand 170. Although some aspects of the device of this disclosure are illustrated with a hand cover device (e.g., a first hand cover 70 and / or a second hand cover 80), it is understood that any aspect of the device of this disclosure may be used with or without a hand cover device, and / or in any combination thereof. As another example, in some scenarios, the user may wear a hand cover on one hand (the first hand) while using the other hand (the second hand) bare (or vice versa). For example, the first hand 170 may remain bare without a first hand cover, and the second hand 180 may be placed on the sports equipment 90 with the second hand cover 80 attached.

[0103] Figures 11A to 11C illustrate the operation of using the strap device 50 together with the sports equipment 90 and the covering device. For illustrative purposes, Figure 11A shows the user attaching the first hand cover 70 and the second hand cover 80 to the sports equipment 90 without showing the strap device 50. Figures 11A and 11B show different side views of the user holding the sports equipment 90 using the first hand cover 70 and the second hand cover 80. In some cases, the first hand cover 70 is threaded through a loop (not shown) before holding the sports equipment 90. In some cases, the grip portion 61 is directly attached to the first hand cover 70. The second hand cover 80 can be used to hold the grip portion 61 and press it against the sports equipment 90. The first hand cover 70 may be for the user's right or left hand, depending on the user's preference.

[0104] Figures 12 to 15 illustrate several aspects of how to operate the device of the present disclosure. Figure 12 shows a method 400 of using the device in one aspect of the present disclosure. In step 410, the method may include securing a first hand to a first hand restraint of the wearable device. In step 420, the method may include placing the first hand around a sports equipment. In step 430, the method may include an optional step of using a second hand to detach the grip portion from the first hand restraint. In step 440, the method may include placing a second hand simultaneously around the sports equipment and the grip portion of the wearable device, thereby allowing the second hand to hold the first hand to the sports equipment through the first hand restraint. In step 450, the method may include swinging the sports equipment along a trajectory to apply or attempt to apply the sports equipment to an approaching object, thereby causing the first and second hands to move together throughout the entire trajectory.

[0105] Figure 13 shows a method 500 of using the device of the present disclosure in another aspect. Method 500 may include a step 510 of placing a first hand on a first hand cover. The first hand cover may include an elongated grip portion extending from the first hand cover. The grip portion may be detachably connected to the first hand cover. In step 520, the method may include placing the first hand cover on a sports equipment. Method 500 may include an optional step 530 of using a second hand to detach the grip portion from the first hand cover. In step 540, method 500 may include placing a second hand on the grip portion of the first hand cover and the sports equipment simultaneously. This allows the second hand to hold the first hand against the sports equipment by the grip portion of the first hand cover. In step 550, method 500 may apply or attempt to apply the sports equipment to an approaching object by swinging the sports equipment along a trajectory of motion. As a result, the first and second hands move together until the completion of their trajectory.

[0106] Figure 14 shows a method 600 for applying the device of the present disclosure in a different aspect. Method 600 may include, as step 610, inserting a first hand into the strap device. The strap device may include a loop portion and an elongated grip portion extending from the loop portion. The grip portion may be detachably connected to the loop portion. In step 620, Method 600 may include placing the first hand on the sports equipment. Method 600 may include an optional step 630 for detaching the grip portion from the loop portion using a second hand. In step 640, Method 600 may include placing the second hand simultaneously on the grip portion of the strap device and on the sports equipment, so that the second hand holds the first hand to the sports equipment via the grip portion of the strap device. In step 650, Method 600 may include applying or attempting to apply the sports equipment to an approaching object by swinging the sports equipment along a trajectory, so that the first and second hands move together throughout the entire trajectory.

[0107] Figure 15 shows a method 700 for applying the device of the present disclosure in a different aspect. Method 700 may include, as step 710, securing the strap device to a first hand. In step 720, Method 700 may include placing the first hand on a sports equipment. In step 730, Method includes placing a second hand on the sports equipment and the strap device, thereby securing the first hand to the sports equipment. In step 740, Method may allow the first hand to be released from the sports equipment when the second hand releases the strap device.

[0108] <Operation> As mentioned above, the strap device 50 can be used to assist a user in maintaining a follow-through motion during sports activities, such as when attempting to hit a ball with a baseball bat or when actually hitting it. Before using the strap device 50, the user can wear the first hand cover 70 and the second hand cover 80. The user can then pass the first hand cover 70 through the loop portion 60 of the strap device 50 so that the user's four fingers pass through the loop portion 60. In this configuration, the grip portion 61 hangs down from the loop portion 60. The user can wrap their fingers (and the second hand cover 80 covering those fingers) around the sports equipment 90 and hold the sports equipment 90 in the desired position. At the same time, the second hand cover 80 can grasp and hold the grip portion 61 of the strap device 50. The user can use their second hand to press down on the grip portion 61 and continue to hold the strap device 50 throughout the swing motion (or attempt thereof).

[0109] As previously stated, the devices disclosed in this disclosure, such as the strap device 250, can be used without a loop. In embodiments of the strap device 250 that do not include a loop (see embodiments of the disclosure shown in Figures 9A and 9B), the grip portion 261 can be integrated with the first hand cover 270. The user can wear the first hand cover 270 and the second hand cover 80 before using the strap device and separate the grip portion 261 from the first hand cover 270. The user can wrap their fingers (and the second hand cover 280 covering those fingers) around the sports equipment 90 to hold the sports equipment 90 in the desired position. At the same time, the second hand cover 280 can grasp and hold the grip portion 261 of the strap device 250. The user can hold and press down on the grip portion 261 with the second hand and hold the strap device 250 throughout the swing motion (or attempt to swing).

[0110] In some situations, when a user uses the strap device 50 during a baseball game, practice, or training session, they may want to hold the sports equipment with both hands throughout the entire motion, from before (or actually hitting) the ball until after the swing is complete. As a result, as long as the user wants to continue holding the sports equipment 90, they can continue to hold (and grip) the grip portion 61 and the sports equipment 90 simultaneously via the second hand cover 80. This allows both hands to swing as one unit, enabling the user to achieve a controlled follow-through motion. If the user wants to release the sports equipment, or separate the actions of the first hand cover 70 and the second hand cover 80 (or, if not wearing a hand cover device, separate the actions of the first and second hands), they simply need to release the pressure from the grip portion 61.

[0111] While certain aspects and features of wearing a hand-covering device (e.g., gloves) on one (or both) hands are described in this disclosure, the scope of this disclosure is not limited to the use of this disclosure with a hand-covering device (e.g., gloves). For example, a user can use this disclosure without wearing gloves and can benefit from it with bare hands. Furthermore, the use of this disclosure is not limited to either the left or right hand. Therefore, the devices disclosed in this disclosure can be used with both the left and / or right hand.

[0112] It should be noted that many variations and modifications are possible to the aspects described herein, and their components should be understood as just one of many other acceptable examples. All such modifications and variations are intended to be included within the scope of this disclosure and protected by the following claims. Furthermore, any of the steps described herein may be performed simultaneously or in an order different from that described herein. Also, as will be apparent, the features and attributes of the particular aspects disclosed herein may be combined in various ways to form additional aspects, all of which are included within the scope of this disclosure.

[0113] The conditional language used herein, such as “can,” “maybe,” “might,” “may,” and “for example,” is generally intended to indicate that a particular aspect includes certain functions, elements, and / or states, while other aspects do not, unless otherwise specified or understood in the context in which they are used. Therefore, such conditional language does not generally imply that functions, elements, and / or states are in any way required in one or more aspects, nor does it imply that one or more aspects necessarily include logic for determining whether these functions, elements, and / or states are included in or performed in a particular aspect, with or without author input or prompting.

[0114] Furthermore, the following terms may be used herein: Unless otherwise clearly indicated in the context, the singular forms “a,” “an,” and “the” include the plural forms. Thus, for example, a reference to an item includes a reference to one or more items. The term “ones” refers to one, two, or more and generally applies to the selection of some or all of a quantity. The term “plural” refers to two or more items. The terms “about” or “approximate” mean that the quantity, dimension, size, composition, parameter, shape, and other characteristics do not need to be exact, but are approximated as necessary and / or may be larger or smaller, reflecting tolerances, conversion factors, rounding, measurement errors, and other factors well known to those skilled in the art. The term “substantially” means that the listed characteristic, parameter, or value does not need to be exactly achieved, and deviations or variations may occur, including, for example, tolerances, measurement errors, limits of measurement accuracy, and other factors well known to those skilled in the art, provided that the degree of such deviation or variation does not interfere with the intended effect of the characteristic.

[0115] In this specification, numerical data may be expressed or presented in range format. Such range formatting is used for convenience and conciseness and should therefore not be interpreted as including only the numerical values ​​explicitly stated as limits to the range, but rather flexibly as including all individual numerical values ​​or subranges within that range, as if each numerical value and subrange were explicitly stated. For example, the numerical range "approximately 1 to approximately 5" should not be interpreted as including only the explicitly stated values ​​from approximately 1 to approximately 5, but should also be interpreted as including the individual values ​​and subranges within the indicated range. Thus, this numerical range includes individual values ​​such as 2, 3, 4, etc., and subranges such as "approximately 1 to approximately 3," "approximately 2 to approximately 4," "approximately 3 to approximately 5," "1 to 3," "2 to 4," and "3 to 5." The same principle applies to ranges that list only a single numerical value (e.g., "greater than approximately 1"), regardless of the width of the range or the characteristics described. For convenience, multiple items may be presented in a common list. However, these lists should be interpreted as if each item in the list were an individually identified, independent, and unique item. Therefore, individual items in such lists should not be interpreted as de facto equivalents to other items in the same list simply because they are presented in a common group, unless explicitly indicated otherwise. Furthermore, when the terms “and” and “or” are used in conjunction with a list of items, they should be interpreted broadly, meaning that one or more of the listed items may be used alone or in combination with other list items. The term “or” refers to selecting one of two or more options, and unless the context clearly indicates otherwise, it does not limit the selection to only the listed options, nor does it mean selecting only one of the listed options at a time.
