The disclosed subject matter relates generally to workout accessories for use with weightlifting. More specifically, the present invention relates to a band comprising that provides a barrier between the user's skin and the workout equipment being gripped.
Weightlifters, both professional and novice, experience injuries on their hands caused by friction between the soft skin of the palm and the workout equipment or other skin. Although the human body will develop calluses on the palm to ease these types of injuries, the calluses take time to form, allowing injury during that time. Further, many find these calluses to be undesirable as they affect the appearance and texture of the hand and may even cause reduced sensation, which, in particular, is undesirable for professionals who may rely on manual dexterity and sensitivity to do their jobs, such as doctors and musicians.
One proposal to protect the hands while weightlifting is to use chalk as described in U.S. Pat. No. 5,565,023 to Sereboff. However, this proposal is deficient as chalk is messy to apply and known to leave residue behind on equipment or clothing. Further, the use of chalk comes with some health risks from breathing in airborne chalk, drying out the skin, and particles entering into cuts, tears, and open wounds in the skin. Additionally, chalk may need to be applied multiple times throughout a workout, and failing to do so may lead to chalk being ineffective at preventing calluses and skin tears.
Gloves have also been proposed to protect the hands while weightlifting as in U.S. Pat. No. 9,844,693 to Jones and 9,421,449 to Ditto. These proposals are deficient, in one respect, as the gloves trap heat, causing users to sweat. Accumulation of sweat in the gloves makes them moist and can exacerbate skin issues, such as eczema. Additionally, the gloves can develop an odor from the sweat and become a breeding ground for bacteria, which can cause further infections to the skin and any open wounds. Further, many weightlifters find that wearing gloves impacts their grip on the weights. In particular, glove users often have trouble feeling equipment through their gloves and fail to optimally adjust their grip. As such, they may not engage all desired muscle groups and can be at risk for injury due to poor form caused by poor grip. It is recommended that users wear gloves with a tight fit—like a second skin—to reduce the impact on grip, however, this makes the gloves difficult to remove and replace during a workout. While some users may elect to leave their gloves on throughout their workout, this can impact fine motor skills necessary for, for example, opening a water bottle, adjusting the fitness equipment being used, turning a door knob, or, in some cases, using a touchscreen to check one's phone. The configuration of the glove fingers, in particular, further limits users from providing additional support to their fingers by a splinting or buddy taping, as they generally separate the fingers from one another.
One proposal to improve traditional weightlifting gloves is U.S. Pat. No. 9,931,533 to Ingram for lifting straps. Such lifting straps provide a tool to improve one's grip on workout equipment without the need for gloves. However, this proposal remains deficient because the straps are not ergonomically designed to prevent the impingement of the user's palm skin when gripping equipment. Instead, they act as a mere cover for the palm. This proposal is further deficient because it fails to correct a user's grip to engage and stimulate a wider range of muscle groups. Instead, it is merely an assist to prevent one's loss of grip. Further, this proposal is deficient because of its time to set up. Users not only have to connect the straps to their hands and wrists, but they also have to engage the straps with each individual piece of equipment they plan to use. Indeed, excess lengths of unsecured strap can easily become caught by the user's limbs or in the equipment, which can lead to injury. As such, the straps must be wrapped repeatedly around the equipment until the strap does not obstruct the user, and, repeatedly unwrapped to disengage them. Thus, it may be seen that lifting straps requires additional time to set up prior to each set of repetitions, which can be significant over the course of a workout. Additionally, as is the case with workout gloves, lifting straps are difficult to clean. They are commonly made of woven or braided nylon or cotton material, which cannot simply be wiped down, leading to the proliferation of bacteria and, consequently, development of an odor.
Thus, although various proposals have been made to reduce the injury to the palm caused by weightlifting, none of those in existence combine the characteristics of the present invention. Therefore, there remains a need for a hygienic device which can protect the skin on the palm of the hand without requiring extensive time and setup, while allowing the user to retain the benefits of tactile feedback from the hand and enhancing the grip to engage additional muscles.
The present disclosure is directed to a gripping apparatus comprising a strap and a cushion configured to provide a barrier between the palm of a user's hand and an object being gripped as well as between portions of a palmar side of the user's hand in order to reduce friction on the skin. The gripping apparatus may be a band made of an elastic material configured to conform to the user's hand and preserve a user's ability to receive tactile feedback while covering portions of the palm to prevent injury.
For purposes of summarizing, certain aspects, advantages, and novel features have been described. It is to be understood that not all such advantages may be achieved in accordance with any one particular embodiment. Thus, the disclosed subject matter may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages without achieving all advantages as may be taught or suggested.
The strap may comprise a first end, a second end, an inner surface, and an outer surface. The cushion may be defined by a front edge and a rear edge spaced apart from one another by a first side edge and a second side edge. Further, the cushion may have an inside and an outside. The inner surfaces of the strap and cushion are defined as the portion of the band that, when worn, contacts the user. The outer surface of the strap and the outer of the cushion are defined as the portion of the band that does not directly contact the user's skin when in use. For example, the outside of the cushion may be configured to contact an object being gripped when in use.
The first end of the strap may connect to the first side edge of the cushion, and the second end of the strap may connect to the second side edge of the cushion. As described, the strap and the cushion may be connected to one another in order to define the band. In some embodiments, one or both of the ends of the strap may be removably securable to the first and second side edges, respectively, to define the band.
In one embodiment, the cushion may be configured to provide a barrier between a user's skin and a gripped object when in use and thus, may prevent friction-related injuries such as blisters, rashes, chafing, torn skin, and other irritation. Additionally, by creating a barrier with the skin, the cushion may prevent the loss of sensation and altered appearance of the hand caused by calluses. The cushion may be further configured to provide a barrier to the skin of a user's interdigital folds itself, reducing friction and skin impingement, and thus friction and impingement-related injuries, between the folds and creases of the user's skin.
The cushion may have a width defined by the length of the front and rear edge and a height defined by at least the length of the first and second side edges. In some embodiments, the front edge and the rear edge may comprise the same length. However, in another embodiment, the front edge and the rear edge may comprise different lengths, as such the cushion may have a different width at the front and rear edges.
In instances where the front and rear edges comprise different lengths, the height of the cushion may be defined by the length of the first and second side edges with consideration to the angle at which the first and second side edges extend from the front and rear edges. In some embodiments, the first and second side edges may have different lengths, as such, it will be recognized that the cushion need not have a uniform length to practice the invention. In a further embodiment, the cushion may have a height greater than the first and second side edges at any point along the width of the cushion. It is contemplated that in instances where the height is not uniform, any of the edges of the cushion may be rounded in order to prevent abrupt changes to the shape or avoid defining a portion of the gripping apparatus by sharp angles that might uncomfortably dig into the wearer's hand. In such an embodiment, the height of the cushion may be sized such that it comprises less than all the height of a user's palm. In another embodiment, the height of the cushion may be sized such that it comprises less than all the distance between the user's Kaplan's cardinal line and a ridge on the palm proximal to the user's fingers. Further, the ridge may be disposed on the inside of the cushion, such that the height of the cushion corresponds to a ridge on the palm proximal to the user's fingers and a distal palmar crease.
The front edge of the cushion may be defined by one or more grooves configured to align with at least one of the fingers of the user. In some embodiments, the cushion may comprise up to four grooves, each groove operative to align with a corresponding one of the user's fingers. For the sake of clarity, it is contemplated that the up to four grooves may be configured to align with any or each of the user's index, middle, ring, and little fingers.
In an embodiment in which the cushion comprises a plurality of grooves, any of the grooves may be offset from another groove or grooves. It is contemplated that the grooves may be offset in order to approximate the natural curvature of a top edge of a palm.
In some embodiments, any of the at least one groove may be defined by at least one peak separating a groove from another groove. It is contemplated that the peak may, in some instances, be configured to separate the user's fingers from one another when in use. In some such embodiments, the at least one groove may be configured such that it provides separation only at the proximal end of the user's fingers, thus allowing a user to adjust their fingers as needed without constraint, allowing a more natural grip and increased tactile feedback. It is further contemplated that by providing separation only at the proximal end of the user's fingers, a user may provide additional support to the fingers, for example by a splint or buddy taping, while wearing the band.
The cushion may comprise a ridge disposed along the inside of the cushion configured to separate portions of the user's skin that might otherwise rub against or impinge on one another. In some embodiments, the ridge may span from the first side edge of the cushion to a second side edge of the cushion. In another embodiment, the ridge may span across less than all the distance between the first side edge and the second side edge of the cushion.
In some embodiments, the ridge may be operative to engage a ridge of skin on a user's palm proximal to the fingers. For example, the ridge of skin on the user's palm proximal to the fingers may be a crease on the user's hand distal to the head of each metacarpal, which a person of ordinary skill in the art will recognize as the palmar digital crease.
It is contemplated that the ridge may be flexible and operative to compress and fit a range of hand sizes. In some embodiments, the ridge may be made out of the same material as the band.
The strap may comprise a solid material, which may beneficially reduce deformation during use and aid longevity of the band. In some embodiments, however, the strap may define one or more apertures. It is contemplated that providing apertures may beneficially increase airflow to the hand when the band is in use.
The band may be worn along any portion of the user's hand and wrist. In some instances, the band may be worn so that the strap rests across the dorsal side of the user's hand and the cushion rests on the palm such that the at least one groove aligns with the proximal phalanges comprising any or all of the user's fingers. Wearing the band as described may provide the barrier to the palm in instances where the user is performing a pulling motion, such as when performing pull-ups on a bar, seated cable rows, or bicep curls while gripping barbells, dumbbells, kettlebells or the like. In some instances, such as when a user is performing a pushing motion against a bar or rigid surface, the band may be worn so that the ridge on the inside of the cushion is aligned between the user's distal palmar crease and proximal palmar crease. In some, more generally, the band may be worn so that the rear edge of the cushion is proximal to a top edge of the user's palm. It is contemplated that in the aforementioned instances, the cushion may increase the girth of the user's grip by increasing the circumference of the object being gripped due to the thickness of the cushion resting between the user's palm and the gripped surface. This increase in circumference and overall girth of the user's grip around a surface, such as workout equipment, may activate more muscles and lead to improved results over those produced under a conventional, relatively narrower grip. Further, the band may be worn around the user's wrist when not in use, allowing the user to keep the band on their person when not in use, reducing the likelihood of losing the band. In addition, by allowing the band to be worn around the user's wrist, the user may quickly access it when alternating between workout sets.
In some embodiments, the cushion and the strap may have the same thickness. It is further contemplated that in some embodiments, the cushion and the strap may have different thicknesses. For example, the cushion may have a greater thickness than the strap, such that the cushion may increase the girth and even the width of the user's grip to activate more muscles in addition to providing a barrier between a user's hand and the object being gripped.
In one embodiment, the band may comprise an elastic material such that it flexes with the user's hand during use and maintains its shape when not in use. Suitable elastic materials may, for example and without limitation, comprise natural or synthetic rubber, nylon, foam, thermoplastic polyurethane, polypropylene, and/or combinations thereof. A person of ordinary skill in the art will appreciate that the provided elastic materials are for example only and other elastic materials may be used. The band may further comprise a material suitable to withstand the friction caused by use, such as rubber, while retaining its shape. One of ordinary skill in the art will also recognize that, in some embodiments, it may be desirable for the band to comprise non-woven materials that will be easily cleaned such as by rinsing or wiping. For example, it is well understood that bacterial accumulation is unhygienic and may result in odors, the non-woven material may increase hygiene and prevent undesired odors. Indeed, in some embodiments, materials comprising the strap and cushion may be molded or even extruded as desired.
As individual human hands vary in size, it is contemplated that the band may be configured to accommodate a variety of hand sizes. In one embodiment, the band may comprise elastic material allowing the band to be stretched such that it may engage a plurality of different widths. In another embodiment, the band may comprise two lengths and a means for adjustably joining such lengths to one another. For instance, the band may comprise hook and loop fasteners, hook and eye fasteners, snaps, a clasp, or the like, allowing a user to manually adjust the band as desired or needed.
Several advantages of one or more aspects of the present invention are that it:
It is an object of this invention to reduce friction on the palm during use. It is another object of this invention to reduce strain on the user's hand joints during use.
It is a further object of this invention to reduce friction-related injuries, such as blisters, rashes, chafing, calluses or torn skin.
It is still a further object of this invention to reduce skin impingements as well as impingement-related injuries such as bruises or blisters.
It is yet another object of the invention to increase engagement of muscles by widening the user's grip.
It is another object of this invention to retain tactile feedback in a user's hand.
It is a further object of the invention to provide a gripping accessory that may be easily cleaned. It is yet another object of the invention to provide a gripping accessory that may be worn in multiple configurations.

The strap 110 may have a first end 111, a second end 113, an inner surface, and an outer surface. With reference to
With particular reference to
Returning to
As shown in
The strap 110 may have a length defined by the distance between the first end 111 and the second end 113. In one embodiment, when worn as illustrated in
The strap 110 may be any width operative to secure the band 100 to the user's hand 202. For example only and not for limitation, the strap 110 may be about 0.25 inches to about 0.75 inches wide. In a further example, the strap 110 may be about 0.43 to about 0.60 inches wide. In yet another example, the strap 110 may be about 0.56 to about 0.65 inches wide.
It is contemplated that the strap 110 may comprise a solid material, as shown in the figures. However, it is also contemplated that the strap 110 may comprise one or more apertures on its surface (not shown). In some embodiments, the strap 110 may comprise embossing, such that the strap 110 may comprise a design, image, logo, pattern, trademark, or other word(s)/phrase(s).
The cushion 120 may be configured to provide a barrier between the skin of a user and an object 160, such as a bar, being gripped as shown in
The width of the cushion 120 may be defined by a distance between the first side edge 121 and the second side edge 123. The distance between the first side edge 121 and the second side edge 123 may be equal to the length of the front edge 127 and the rear edge 125. The front edge 127 and the rear edge 125 may comprise different lengths, thus the cushion 120 may have a non-uniform width. With particular reference to
In an exemplary embodiment, as shown in
With continued reference to
It is contemplated that the cushion 120 may have any height appropriate to provide a barrier to any portion of the user's palm 200. It is contemplated that the cushion 120 may provide a barrier to the entire length of the user's palm 200 or less than all the length of the user's palm 200. In an exemplary embodiment shown in
In some embodiments, the cushion 120 may comprise a smooth, solid material, as shown in the figures. However, it is contemplated that the cushion 120 may be embossed, so that the cushion 120 may feature, display, or otherwise comprise a design, image, logo, pattern, trademark, or other word(s)/phrase(s). In one embodiment, the embossing may be disposed on the inside of the cushion 120. In another embodiment, the embossing may be disposed on the outside of the cushion 120. Further, the embossing may be disposed on the inside and the outside of the cushion 120. In some embodiments, the material may even be textured to further increase friction and improve grip security on a surface.
The cushion 120 may have any thickness operative to provide a barrier between the user's palm 200 and the object 160 being gripped. It is further contemplated that the thickness of the cushion 120 may widen the user's grip in order to stimulate a wider range of muscles when performing a workout. Exemplary thicknesses may include from about 0.01 inches to about 0.44 inches and from about 0.1 inches to about 0.3 inches. In some embodiments, the cushion 120 may have the same thickness throughout or may comprise a variety of thicknesses. For example, and without limitation, the thickness of the cushion 120 at the rear edge 125 may be thinner than the thickness at the first side edge 121. As a further clarifying example, the rear edge 125 and the front edge 127 of the cushion 120 may be thinner than a central portion of the cushion 120 to reduce resistance when bending the cushion 120 allowing the cushion 120 to form to the user's hand, preventing the rear edge 125 and front edge 127 from digging into the user's palm 200.
With particular reference to
In some embodiments, the ridge 122 may span the distance between the first side edge 121 and the second side edge 123, thus the ridge 122 may have a length equal to the width of the cushion 120. However, it is contemplated that the ridge 122 may, in some embodiments, span less than all the distance between the first side edge 121 and the second side edge 123.
It is contemplated that the ridge 122 may have any dimensions suitable to create separation between the skin on the user's hand 202. For example, the ridge 122 may have a height in the range of about 0.10 inches to about 0.40 inches. In another example, the ridge 122 may have a height in the range of about 0.15 inches to about 0.35 inches. As yet another example, the ridge 122 may have a height in the range of about 0.20 inches to about 0.31 inches.
In some embodiments, the configuration of the ridge 122 may be defined by the slope angle of each side of the ridge 122 relative to the same-side edge 125, 127 of the cushion 120. In some embodiments, for example, a side of the ridge 122 corresponding to the rear edge 125 of the cushion 120 may have a slope angle of about 20° to about 40° with respect to the cushion 120. The same may be said for the slope angle of a side of the ridge 122 corresponding to the front edge 127 of the cushion 120. In some embodiments, a side of the ridge 122 may have a slope angle of about 20°, 25°, 30°, 31°, 32°, 35°, and 40° with respect to the corresponding front or rear edge 125, 127 of the cushion 120. Those of ordinary skill in the art will recognize an entire range of sloping sufficient to practice the invention, and further, that each side of the ridge 122 may be sloped to a greater or lesser degree than the other side of the ridge 122 relative to the cushion 120.
In some embodiments, the ridge 122 may be flexible in order to allow the ridge 122 to conform to a surface in contact with the inside of the cushion 120. As shown in
The width of the ridge 122 may be any size suitable for separation while allowing for the user to grip the object 160 as shown in
With particular reference to
As shown in
In one embodiment, the at least one groove 124 may, for example, have a width in the range of about 0.25 to about 4.0 inches. The at least one groove 124 may further have a width in the range of about 0.5 to about 1.15 inches. In a further exemplary example, the at least one groove 124 may have a width in the range of about 0.75 to about 1.25 inches.
In an embodiment shown in
A second groove may be operative to engage a user's middle finger and thus may be sized accordingly, for example, having a width selected from a range of about 0.6 to about 1.13 inches. The second groove may further have a width in the range of about 0.65 to 0.87 inches. Further exemplary widths for the second groove may be in the range of about 0.7 to about 1.0 inches.
A third groove may be operative to engage a user's ring finger and thus may be sized accordingly. For example, the third groove may have a width in a range of about 0.53 to about 1.0 inches. It is further contemplated that the third groove may have a width in a range of about 0.62 to about 0.75 inches. In some embodiments, the range may be from about 0.69 to about inches.
A fourth groove may be operative to engage a user's little finger and thus may be sized accordingly and thus may have a width in the range of about 0.43 to about 0.93 inches. It is further contemplated that the fourth groove may have a width in the range of about 0.5 to about inches. In some embodiments, the range may be from about 0.62 to about 0.81 inches.
Notwithstanding the foregoing, in some embodiments, the width of each groove may be selected to widen the user's grip relative to such user's natural resting or even unaugmented gripping position. That is, the width of each groove may be selected to gently separate the user's fingers from one another when in use. As such, it is contemplated that each groove may be relatively wider than each of a user's fingers, though this may not be necessary to practice the invention.
