Definitions
- the present invention relates to exercise equipment. More particularly, the present invention relates to equipment for protecting a user's wrist and hand during exercise.
- Wrist wraps generally comprise one or more straps that wrap around the user's wrist and had support through slight compression of the joint and the added stiffness of the wrap. Wrist wraps are especially helpful for exercises that involve movement of a barbell, dumbbell, or other load above the lifter's head, and help prevent fatigue in the wrist joint which may set in before the lifter's larger muscles have been sufficiently fatigued.
- Palm grips are intended to alleviate this issue. Palm grips generally comprise a leather or other material strap secured to the wearer's wrist and to the base of the wearer's fingers such that the leather strap covers the wearer's palm. The strap, therefore, bears the majority of the friction between the wearer's hand and the ring or bar.
- Such high-intensity exercise regimens often utilize workouts that utilize 2-4 different movements that each target different body parts and athletic skills.
- one workout might involve a series of shoulder-to-overhead barbell presses (for which an athlete may wish to have the additional wrist support of wrist wraps), bodyweight pull-ups (for which an athlete may wish to have the palm protection of palm grips), and “wall ball shots” (which involve tossing a medicine ball to an overhead target and then catching the ball, an exercise for which an athlete may prefer to have bare hands to better handle the ball).
- this workout may be set up as a competition between athletes for the shortest time to complete a given number of repetitions of each exercise or as a set time period in which the athletes compete to amass the most number of repetitions of each exercise. In either case, the athletes are racing to move as fast as possible through the movements.

Abstract
Description
- This application is a continuation-in-part of U.S. patent application Ser. No. 15/630,570 filed Jun. 22, 2017 and claims the benefit of that application and of U.S. Provisional Appl. No. 62/353,140 filed Jun. 22, 2016, both of which are incorporated by reference as if disclosed herein in their entirety.
- The present invention relates to exercise equipment. More particularly, the present invention relates to equipment for protecting a user's wrist and hand during exercise.
- Weightlifters have been using wrist wraps to protect and support their wrists during lifts for many years. Wrist wraps generally comprise one or more straps that wrap around the user's wrist and had support through slight compression of the joint and the added stiffness of the wrap. Wrist wraps are especially helpful for exercises that involve movement of a barbell, dumbbell, or other load above the lifter's head, and help prevent fatigue in the wrist joint which may set in before the lifter's larger muscles have been sufficiently fatigued.
- Gymnasts have been using palm grips for many years to protect the palms of their hands during movements that involve rings, pull-up bars, and the like. Such movements involve very high levels of force applied by the gymnast to the rings or bar. This force is translated via friction between the gymnast's palm and the rings or bar. Many repetitions of such movements can cause injury to the gymnast's palms in the form of blisters or even painful tears to the skin. Palm grips are intended to alleviate this issue. Palm grips generally comprise a leather or other material strap secured to the wearer's wrist and to the base of the wearer's fingers such that the leather strap covers the wearer's palm. The strap, therefore, bears the majority of the friction between the wearer's hand and the ring or bar.
- In recent years, fitness experts have increasingly advocated that cross training provides health benefits to individuals across a variety of athletic skill levels. Fitness experts have also identified additional benefits of high-intensity fitness training to both elite athletes and the general population. The result has been the increasing popularity of cross training exercise regimens that emphasize use of multiple types of exercise movements in high-intensity workouts.
- Such high-intensity exercise regimens often utilize workouts that utilize 2-4 different movements that each target different body parts and athletic skills. For example, one workout might involve a series of shoulder-to-overhead barbell presses (for which an athlete may wish to have the additional wrist support of wrist wraps), bodyweight pull-ups (for which an athlete may wish to have the palm protection of palm grips), and “wall ball shots” (which involve tossing a medicine ball to an overhead target and then catching the ball, an exercise for which an athlete may prefer to have bare hands to better handle the ball). Further, this workout may be set up as a competition between athletes for the shortest time to complete a given number of repetitions of each exercise or as a set time period in which the athletes compete to amass the most number of repetitions of each exercise. In either case, the athletes are racing to move as fast as possible through the movements.
- In this context, it is extremely time consuming for the athlete to change between wrist wraps, palm grips, and bare hands multiple times during the workout. The lost time encourages athletes to forego wrist wraps and palm grips, which substantially increases the risk that the athlete will injure his or her wrist and/or hand. Furthermore, it is inconvenient for an athlete to have to organize and carry multiple pieces of protective equipment in his or her bag, which increases the possibility that the athlete will forget his or her wrist wraps or palm grips and, therefore, increase the risk of injury.
- What is needed therefore, is a device that provides athletes with the ability to shift quickly and conveniently between palm protection and bare hands without sacrificing wrist support and protection.
- It is an object of the present invention to provide both wrist support and palm grip protection in a single device, while permitting the user to conveniently remove the palm grip protection while maintaining the wrist support.
- It is an object of the present invention to provide such a device in which the palm grip protection will not be in the way of the user when it is not in use.

FIGS. 7a and 7b are views of an additional embodiment of the present invention. -
FIGS. 1 and 2 show perspective views of a first embodiment of the present invention in the form ofwrist support 10.Wrist support 10 comprises afirst strap 11 and asecond strap 12. Thefirst strap 11 has awrist pad 13 attached to it, as well asfastening system 14. In this embodiment, thefastening system 14 is a two-component fastener comprising afirst component 14 a and a second component 14 b. In this embodiment, the fastening system is a hook-and-loop system (such as Velcro), in whichcomponent 14 a is the hook portion and component 14 b is the loop portion. - The
first strap 11 also has aloop ring 15 attached to a first end 16 of thestrap 11. Theloop ring 15 is sized so that thesecond end 17 of the first strap can be fed through it and folded back onto itself. In this arrangement, thefastener components 14 a and 14 b can be secured to one another so that the first strap forms a loop. To achieve this, both of thecomponents 14 a and 14 b of thefirst fastening system 14 are attached to the same side of thefirst strap 11. Thefirst strap 11 has a length appropriate for wrapping around a user's wrist, as shown inFIGS. 3 and 4 . Different lengths of the first strap are used in different embodiments to accommodate different user wrist sizes. In this context, the length of the first strap refers to the distance between the first end 16 and thesecond end 17. The length of the first strap and the positioning of thefastener components 14 a and 14 b are selected to give the user the ability to adjust the tension of the device around his or her wrists and to accommodate multiple wrist sizes. - The width of the first strap is selected to provide adequate support for the user's wrist during weightlifting movements or other exercises. The width is varied in other embodiments to be appropriate for different amounts of support and/or different types of exercise.
- The
first strap 11 of the first embodiment comprises a flat webbing formed of a suitable material, such as nylon, polypropylene, cotton, or other material or blend of materials. In some embodiments, the strap is a woven webbing, in others it is a suitable unitary construction. - The
second strap 12 is attached to the first strap via anattachment system 18. Thesecond strap 12 is adapted to provide protection to a user's palm and/or to improve the ability of a user to grip an object with his or her hand. In the embodiment shown, thesecond strap 12 is similar to a gymnastics palm grip in material and construction. Thestrap 12 includes twofinger openings 19 adapted to receive a user's fingers as shown inFIG. 3a . Thesecond strap 12 has awrist end 20 and afinger end 21 and is sized to extend from a user's wrist to the base of the user's fingers. In this context, the length of thesecond strap 12 refers to the distance between thewrist end 20 and afinger end 21. - In the embodiment shown, the
second strap 12 is comprised of a leather material. In other embodiments, thesecond strap 12 is comprised of a synthetic leather, a suitable strap webbing material, or any other material that is suitable for use as a gymnastics palm grip. Such materials are sufficiently strong and resilient to withstand the significant friction created between a user's palm and a pull-up bar, for example, but are sufficiently soft and flexible so as not to create excess friction and chafing on the user's palm and/or fingers. - In the embodiment shown, the
pad 13 is comprised of a neoprene foam. Other foam types and other materials are used for the pad in other embodiments. - The attachment system 16 of the
device 10 permits thesecond strap 12 to pivot relative to thefirst strap 11. The pivoting or rotating motion is illustrated byarrows 23 shown inFIG. 2 . As shown inFIGS. 3a, 3b, and 3c , the pivoting motion allows the second strap to move between: (1) a first position shown inFIG. 3a in which thestrap 12 is substantially perpendicular to thefirst strap 11 and thesecond strap 12 provides protection to the user's palm; and (2) a second position shown inFIG. 3c in which thestrap 12 is substantially parallel to thefirst strap 11 and thestrap 12 is secured out of the user's way. In this context, the references to perpendicular and parallel refer to the relationship between the lengths of the first and second straps. - The embodiment shown also includes a second fastening system 22 which is used to secure the
second strap 12 into its second position. In this embodiment, the second fastening system 22 comprises a two-component fastener with afirst component 22 a attached to the second strap 12 (shown inFIG. 1 ) and a second component 22 b attached to the first strap 11 (shown inFIG. 2 ). In this embodiment, the second fastening system 22 is a hook-and-loop system, in which thefirst component 22 a is the hook portion and the second component 22 b is the loop portion. The second component 22 b is positioned so that it aligns with thefirst component 22 a when the first strap is secured on a user's wrist and thesecond strap 12 is wrapped around the wrist into its second position. -
FIGS. 3a, 3b, and 3c show thedevice 10 being worn by a user. In these figures, thefirst strap 11 is wrapped snuggly around the user's wrist to provide support to that joint for, especially, weightlifting movements involving a barbell or dumbbells. InFIG. 3a , thesecond strap 12 is in a first position to provide palm protection to the user. The user's fingers 24 have been placed through thefinger openings 19 so that thesecond strap 12 is secure in first position and does not move while the user performs exercises that bear against thestrap 12. -
FIG. 3b shows thesecond strap 12 being pivoted about theattachment system 18.Arrows 25 indicate the path of movement that the attachment system enables for thesecond strap 12. Once the user no longer needs the palm grip protection provided by the second strap in its first position, he or she slips his or her fingers out of thefinger openings 19 and then simply rotates the second strap either clockwise or counterclockwise. The user can secure the second strap out of his or her way by aligning it in parallel with the first strap and then wrapping the second strap around the first strap and pressing the components of the second fastening system together. -
FIGS. 3c and 4 show thesecond strap 12 secured into its second position. As shown, the lengths of thefirst strap 11 and thesecond strap 12 are essentially parallel.FIG. 4 shows how the second fastening system 22 secures thesecond strap 12 in the second position. Thefirst component 22 a of the system, which is attached to thesecond strap 12, is pressed onto the second component 22 b, which is attached to thefirst strap 11. The second fastening system secures the second strap out of the user's way so that it does not become a distraction or a danger while the user performs exercises that do not require palm grip protection. - In this embodiment, the
second strap 12 is sized, and the second component 22 b of the fastening system is positioned, such that the second strap should be wrapped around the wrist in the direction away from theloop ring 15 to ensure that the second fastening system functions. -
FIG. 5 shows an exploded view of theattachment system 18 used in this embodiment of the invention in relation to other components of thedevice 10. Thesecond strap 12 has a reinforced portion 26 adjacent thewrist end 20. In this embodiment, the reinforced portion 26 comprises a double layer webbing—i.e. a webbing folded over one end of thestrap 12 and attached using abox stitch 27. The reinforced portion 26 of thesecond strap 12 includes anopening 28 in the form of a hole made through the reinforced portion 26. In this embodiment, theopening 28 includes ametal grommet 29. In other embodiments, the reinforced portion 26 is comprised of a leather, synthetic leather, or other sufficiently strong and resilient material. In other embodiments, other types of eyelets are used in place ofgrommet 29, such as other rivet-style components. - The first end 16 of the
first strap 11 is also shown. It includes the webbing of the first strap folded over onto itself in order to attach theloop ring 15. Anopening 30 is also formed in thefirst strap 11 adjacent to the first end 16. Theopening 30 and theopening 28 are sized and located to receive theattachment system 18, which enables thesecond strap 12 to pivot relative to thefirst strap 11. Theattachment system 18 comprises screw portion 31 and abase portion 32. The screw portion includes external threading that engages a complementary internal threading on thebase portion 32. In this embodiment, the attachment system also includes a washer 33 disposed between the screw portion 31 and thefirst strap 11. To assemble theattachment system 18 and attach the first and second straps together, thebase portion 32 is inserted into theopening 28 of the reinforced portion 26, then inserted into theopening 30, then the washer 33, and then the screw portion 31 is screwed into thebase portion 32 until it is sufficiently snug. - When the screw portion 31 is threaded into the
base portion 32, they form essentially a rod around which the straps can pivot. In some embodiments, the base portion is integrally attached to one of the first or second straps. Other types of pivoting attachment systems are used in other embodiments, including more permanently attached pivoting rivet style attachments. In some embodiments, the screw portion, base portion, and other components of the attachment system are stainless steel. In other embodiments, these components are formed of other appropriate metals, composite materials, and thermoplastics, or combinations thereof. -
FIG. 6 shows a second embodiment of the present invention.Device 110 comprises a two-piece first strap 111 and asecond strap 112. The first strap 111 comprises apad portion 113 and astrap portion 140. As in the embodiment ofFIGS. 1-5 , the first strap 111 is sized and designed to wrap around a user's wrist to provide support during weightlifting exercises, or any movement for which the user desires additional support for the wrist joint. - The first strap 111 includes a first fastening system 114, with a
first component 114 a attached to thepad portion 113 and a second component 114 b attached to thestrap portion 140. The two components of the fastening system are on opposite sides of the first strap 111. This enables a user to simply wrap thefirst strap 11 around his or her wrist and press the second component 114 b against thefirst component 114 a to secure the strap in place. In this embodiment,component 114 a is a loop portion of a hook-and-loop system, while component 144 b is the hook portion. The length of the strap is again selected so that the user can adjust the tightness of the wrap and/or to accommodate different sized wrists. - The
second strap 112 is attached to the first strap 111 via therotating attachment system 118. In this embodiment, the attachment system comprises a thumb screw and a base for receiving the thumb screw. The thumb screw and base form the rod that fits through openings formed in both of the straps (not shown). This permits thesecond strap 112 to rotate relative to the first strap 111. - The
device 110 also includes a second fastening system 122 for securing thesecond strap 112 to the first strap 111 in a manner similar to that shown inFIGS. 3c and 4. Second fastening system has two components:component 122 a attached to the second strap 112 (in the form of two pieces of the hook portion of a hook-and-loop system) and component 122 b attached to the first strap 111. As in the embodiment ofFIGS. 1-5 , thesecond strap 112 can be pivoted so that it is substantially parallel to the first strap 111 and then secured in this position by pressing the components of the second fastening system 122 together. Advantageously in the embodiment ofFIG. 6 , the entire outside surface of the first strap 111 has the loop portion of a hook-and-loop system so that the second strap can be secured in the second position no matter how far the finger end 121 reaches around the first strap 111 when it is on a user's wrist. In this design, thefirst component 114 a of the first fastening system and the second component 122 b of the second fastening system are essentially one and the same component. That is, a single piece of loop fabric is used by both fastening systems. - The embodiment shown in
FIG. 6 includes asingle finger opening 119 instead of two finger openings as shown for the embodiment ofFIGS. 1-5 . Theopening 119 is sized to accommodate two of the user's fingers. Of course, other embodiments employ different numbers of finger openings of varying size. - The fastening systems used in the embodiments of
FIGS. 1-5 andFIG. 6 are hook-and-loop type systems. But, other types of fastening systems are used in other embodiments, such as buckles, snaps, buttons, or other types of fabric and/or touch fasteners. In some embodiments, fastening systems that use two components of the same kind are used, for example, 3M's DualLock system. In such embodiments, both components have the same design. In some embodiments, a magnetic fastening system is used. In such embodiments, at least one first magnet is used in conjunction with either a second magnet or a ferromagnetic material (such as certain metals) to which the first magnet is attracted. For example, the second fastening system in some embodiments comprises a first magnet attached to the second strap and a second magnet or ferromagnetic material attached to the first strap. - The spacing of the various parts attached to the first strap is important to the functioning of embodiments of the invention. For example, the second component of the second fastening system 22 b, 122 b must be placed on the
first strap 11, 111 at a position that is appropriate for the distance between the pivot point of the second strap (i.e., theattachment system 18, 118) and thefirst component FIG. 6 , this is achieved by ensuring that the second component 122 b (or the combination of thecomponent 114 a and component 122 b) extends to a distance from theattachment system 118 along the first strap 111 equal to the distance along thesecond strap 112 from the attachment system to thefirst component 122 a. When this condition is true along both thepad portion 113 and thestrap portion 140, thesecond strap 112 will always be able to be secured into its second position. - For embodiments in which the first strap utilizes a loop ring or another feature so that the first strap doubles back on itself to be secured, reference is again made to
FIGS. 1 and 2 . Thefirst strap 11 has afirst side 41 on which the components of the first fastening system are attached. The second component 22 b of the second fastening system is attached to thesecond side 42. The second component 22 b is sized and positioned so that it is the same distance from theattachment system 18 around which the second strap pivots as the distance along the second strap between theattachment system 18 and thefirst component 22 a. - In general, the second component 22 b extends about the same distance along the
second side 42 from thesecond end 17 as the second component 14 b extends along thefirst side 41 from thesecond end 17. Thespace 43 between the twocomponents 14 a and 14 b is generally the space that permits the fit of the strap to be varied around the wrist of a user. This is the portion of the strap that can easily be moved within theloop ring 15. - The relationships between the length of the second component 22 b, the length of the
space 43, the distance between theattachment system 18 and thefirst component 22 a, and the distance between theattachment system 18 and the far edge of thefirst component 14 a in the embodiment shown are as follows: The ratio of the length of the second component 22 b to the length of thespace 43 is about 2.75:2.5. The ratio of the length of the second component 14 b to the length ofspace 43 is about 3.25:2.5. The distance between theattachment system 18 and thesecond component 22 a is about the same as the distance between theattachment system 18 and the far edge of thefirst component 14 a. The ratio of the length of the second component 22 b to the length of the second component 14 b is about 2.75:3.25. When the device is sized up or down, preserving these ratios ensures that thesecond strap 12 can be safely secured in its second position while still allowing adjustability in the fit of the device. At a minimum, the second component 22 b is sized and positioned such that, when the first strap is folded back onto itself through the loop ring, the second component 22 b extends far enough that it can be reached by thefirst component 22 a on the second strap. In other embodiments, the ratio between the length of the second component 22 b and thespace 43 is about 3:2, about 3:2.5, about 1:1, or about 2:1. -
FIGS. 7a and 7b show an additional embodiment of the invention in which analternative attachment system 218 is used to attach thefirst strap 211 tosecond strap 212. In this embodiment, theattachment system 218 comprises astitching arrangement 250 in the shape of a right triangle. Thestitching arrangement 250 is used to secure the first strap to the second strap. The triangular shape of thestitching arrangement 250 enables thefirst strap 212 to be folded over the stitch line that forms the hypotenuse of the triangle. This folding action permits thesecond strap 212 to pivot between a first position in which thestrap 212 is substantially perpendicular to thefirst strap 211 and thesecond strap 212 provides protection to the user's palm; and (2) a second position in which thestrap 212 is substantially parallel to thefirst strap 211 and thestrap 212 is secured out of the user's way. -
FIG. 7a shows the device in the configuration in which thesecond strap 212 is positioned to provide protection to a user's palm and is substantially perpendicular to thefirst strap 211. In the embodiment shown, the shorter leg of the triangle is substantially parallel with the hand, substantially parallel with the second strap, substantially parallel with a longitudinal dimension of the second strap, and substantially perpendicular to thefirst strap 211. The stitch line that forms the hypotenuse of the triangle is at about a 45 degree angle to the longitudinal dimensions of the first and second straps, which allows thesecond strap 212 to fold at a roughly perpendicular angle to attach to the first strap. The longitudinal direction of the straps refers to the long dimension of the strap. -
FIG. 7b shows the device in the configuration in which thesecond strap 212 is wrapped around thefirst strap 211, and is substantially parallel to thefirst strap 211. The fold in thesecond strap 212 is shown at 251. In this embodiment, thesecond strap 212 includes afastening system 222 for securing thesecond strap 212 in the second position wrapped around the first strap. In this embodiment, thefastening system 222 comprises a hook-and-loop fastener, and the hook portion is located on thesecond strap 212. In the embodiment shown, thesecond strap 212 is adapted to wrap over the loop ring on thefirst strap 211. In other embodiments, thesecond strap 212 is adapted to wrap in the other direction on thefirst strap 211—away from the loop ring. - In other embodiments, only a single stitch line is necessary. In some embodiments, the stitch line is made at a 45 degree angle to the longitudinal direction of each of the first and second straps, similar to the hypotenuse stitch line shown
FIG. 7 a. - Thus, in some embodiments, the attachment system comprises at least one stitch line securing the first strap to the second strap and the stitch line is positioned so that the second strap pivots between the first and second positions by folding over the stitch line. In some embodiments, the at least one stitch line comprises an arrangement of stitching comprising a triangular shape with a first stitch line substantially aligned with a longitudinal dimension of the first strap, a second stitch line substantially perpendicular to the first stitch line, and a third stitch line connecting the first and second stitch lines and over which the second strap folds.
- Those of skill in the art will appreciate that a variety of other features and embodiments can be employed without departing from the spirit of the invention.
