Description

TECHNICAL FIELD

The present disclosure relates to the field of sporting equipment. More specifically, the present disclosure relates to a device for facilitating hand gripping in sporting and other manual activities.

BACKGROUND

Athletes participating in sports that involve hand manipulations such as, for example, basketball, tennis, baseball, handball, and many others, are frequently reluctant to wear gloves. The primary reason for this is the loss of tactile sensitivity that may be caused by the gloves. The athletes may feel that hand sensitivity and dexterity is essential in the performance of their sport.

Hand adhesion to balls, tennis rackets, poles used in pole vault, and the like, with good sensitivity, is therefore of primary importance to the athletes. Various conditions such as excessive heat, cold, sweat, rain, oily skin, and the like, could be overcome by wearing gloves, but the resulting loss of sensitivity and/or loss of dexterity would be unacceptable.

An alternative to gloves is the use of tape wrapped around the fingers and/or on the palm of the hand of the athlete. Such tape is usually used to prevent sweat from being in contact with balls, tennis rackets and other sporting accessories, while preserving a “skin-touch” feeling with the sporting accessories. However, athletes have to heavily wrap their fingers in order to ensure that the tape will remain in place during a complete sport session, frequently causing harm to the overall blood flow in the athlete's hand. Similarly, usage of adhesive medical bandages is less than ideal due to their thicknesses, particularly in their cushioned areas.

The challenge for athletes is to ameliorate grip with their hands, continuously over the course of a sporting event, without any perceivable loss of sensitivity and of dexterity.

Therefore, there is a need for improvements in sporting devices that compensate for problems related to the lack of grip that athletes may experience and to the loss of tactile sensitivity that athletes wish to avoid.

In one embodiment, the device 100 may be configured to be worn on a finger of an athlete's and may comprise an adhesive being configured to stick to human skin, allowing the device 100 to be wrapped or to be folded around a finger of the athlete's hand. Therefore, a longitudinal size of the device 100 may be equivalent to a length of the finger, so that the device 100 may entirely cover the finger on a palm side of the hand. A placement of the device 100 on the finger of the athlete's hand is described with greater details hereinafter.

FIG. 2 is an image of two devices 100′ worn by an athlete in accordance with one embodiment of the present technology. As illustrated on FIG. 2, the devices 100′ may entirely cover index and major fingers of an athlete's hand 200, on a palm side of the hand 200. FIG. 2 also shows the outer surfaces of the devices 100′. Note that the athlete may choose to wear one or both of the devices 100′ and may choose to wear additional devices on other fingers. This aspect is not limitative and corresponds to a personal choice of the athlete, a grip and/or adherence level needed depending on the performed sport, and/or external conditions that may cause the athlete to adjust his grip and/or adherence by adding or removing one or more device 100. A shape and a composition of the device 100 are further described in greater details hereinafter.

FIG. 3 is a schematic representation of a composition of the device 100 in accordance with one embodiment of the present technology. The device may comprise a foldable substrate 610. In various embodiments, the foldable substrate 610 may either be stretchable or inelastic, as a choice of a degree of a stretchiness of the foldable substrate 610 may be provided to the wearer.

The foldable substrate 610 may be formed of knits or woven textiles, for instance and without limitations nylon or polyester; non-woven textile, for instance and without limitations microfiber; or plastic films, for instance and without limitations Polyvinyl chloride (PVC), polyethylene or polyurethane. The foldable substrate 610 may have a thickness between 0.05 mm, for instance for Thermoplastic polyurethane films (TPU), and 1.2 mm, for instance for microfibre on the palm side of the hand 200. The person of ordinary skill in the art will be able to select these and other materials, as well as a suitable thickness of the foldable substrate 610, to allow the athlete to keep a high sensitivity and dexterity level.

An upper surface of the foldable substrate 610 may be textured to increase a grip strength of the athlete, the upper surface of the foldable substrate 610 provides a gripping interface the device 100 with a sporting accessory, such as for example a ball or a tennis racket. In the same or another embodiment, the upper surface may be entirely or partially covered with an additional layer 630 configured to further increase a grip strength at desired location of the upper surface of the foldable substrate 610. Therefore, in an embodiment, the additional layer 630 may define continuous or non-continuous regions on the upper surface of the foldable substrate 610 as illustrated in FIG. 2. The additional layer 630 may, for example and without limitation, be formed of flexible film such as thermo-plastic elastomer, silicon, fabric material such as non-woven material, microfiber, woven or knit textile; coating such as latex, PVC, polyurethane; nitrile, tar compound, or any other suitable material, or any combination thereof. The additional layer 630 may comprise a textured material (e.g. a textured fabric, a textured rubber, and the like). Without limitation, a point density of the additional layer 630 of textured material may be in a range between 16 and 900 points per square inch. In another embodiment, the additional layer 630 may comprise a material having a modest level of stickiness, the additional layer 620.

The foldable substrate 610 may comprise a plurality of regions separated by textured material, each of the plurality of regions defining a shape in the textured material and being configured to provide increased grip strength at desired locations of the foldable substrate 610. In the same or another embodiment, two regions of the plurality of regions may be formed of different materials. The foldable substrate 610 may be formed of material similar to aforementioned additional layer 630 under a textured form.

A lower surface of the foldable substrate 610 comprises an adhesive 620 configured to stick to human skin, thereby interfacing the device 100 with a finger of the athlete's hand 200. The adhesive 620 may be significantly stickier than the additional layer 630. Prior to usage, the adhesive 620 may be covered by a releasable layer 622, for example and without limitation a release paper liner, a plastic film, or the like. The adhesive 620 may be formed of acrylic, acrylate, methacrylate, epoxy diacrylate or other vinyl resins.

In an embodiment, the releasable layer 622 may comprise one complete strip of material that may be removed in one operation. In another embodiment, the releasable layer 622 may be divided into multiple portions. The releasable layer 622 may thus define a plurality of portions covering the adhesive 620. In an embodiment, a main portion of the releasable layer 622 may correspond to a main section of the device and one more flap portions of the releasable layer 622 may correspond to one or more flaps of the device 100, so that each portion of the releasable layer 622 may be removed from the foldable substrate 610 separately. In this embodiment, the releasable layer 622 may include perforation lines 624 (FIG. 4) separating the portions. Each portion of the releasable layer 622 may therefore be detachable from the other ones along these perforation lines 624.

FIG. 4 is an image of the device 100 in accordance with one embodiment of the present technology. FIG. 4 depicts an inner face of the device 100 being covered by the releasable layer 622. In the shown embodiment, the foldable substrate 610 of the device 100 comprises a main section 1 covered by a main portion of the releasable layer 622 and a plurality of flaps extending from the main section 1, each flap being covered by a respective flap portion of the releasable layer 622. In the non-limiting embodiment of FIG. 4, a first flap 2 is located at a forward extremity of the main section 1. A second flap 3 extends on one side of the main section 1, and a third flap 4 extends on an opposite side of the main section 1. In the illustrative embodiment of FIG. 4, the device 100 thus comprises three flaps 2, 3 and 4 extending from the main section 1. It is contemplated that the device 100 may comprise a different number of flaps, so the releasable layer may comprise a different number of flap portions.

It should be understood that the embodiment illustrated on FIG. 4 is a mere example of a shape of the device 100 and that device 100 may have a different shape. Notably, in another embodiment, the device 100 may have five different shapes, each shape being sized and configured to be worn on a respective one of the five fingers of the athlete's hand. Additionally, the device 100, or kits including a plurality of devices 100 configured to be worn on various fingers of the athlete's hand, may be produced in various sizes suitable for use by persons with various hand sizes.

With continued reference to the illustrative embodiment of FIG. 4, the main section 1 is configured for placement, after removal of the releasable layer 622, on a palm side of one of the fingers of the hand 200. Following placement of the main section 1, a top end 1a of the main section 1 may be placed on a distal phalanx of the finger, a bottom end 1b of the main 1 section being then placed on a proximal phalanx of the finger. Once the finger in placed in contact with the main section 1, the first flap 2 may be folded around a tip of the finger. In the same or another embodiment, the first flap 2 may be configured to be folded on a dorsal side of the finger, the dorsal side being opposition to the palm side of the finger, thereby partially covering a nail of the finger. Once the first flap 2 is folded on the finger, the second flap 3 may be folded around the finger on a first lateral side of the finger, thereby covering an area of the dorsal side of the finger. In the same or another embodiment, the second flap 3 may be configured to cover at least in part the first flap 2 located on the dorsal side of the distal phalanx of the finger. Once the second flap 3 is folded on the finger, the third flap 4 may be folded around the finger on a second lateral side of the finger, thereby covering another area of the dorsal side of the finger. In the same or another embodiment, the third flap 4 may be configured to cover at least in part the second flap located on the dorsal side of the finger. Each operation leading to the placement of the main section 1 and of the flaps 2, 3 and 4 on the finger may comprise successive removals of the portions of the releasable layer 622, which may be torn along the perforation lines 624.

The main section 1 and the flaps 2, 3 and 4 may be maintained folded around the finger by the adhesive 620 (FIG. 3), located on the bottom side of the foldable substrate 610 interfacing with the finger. Use of any other suitable manner to maintain the device 100 on the finger is also contemplated.

Note that the order of the aforementioned operations for folding the different flaps 2, 3 and 4 on the finger is not a limitative aspect to the present disclosure. It is only a mere example of operations for placement of the device 100. As an example, the first flap 2 may be folded around the finger once the second flap 3 and the third flap 4 are folded on the finger.

It should be understood that a removal of the device 100 from the finger may be performed by unfolding the various flaps 2, 3 and 4, operations for removing the device 100 being performed in a reverse order from the placement of the device 100. Additionally or alternatively, operations for removing the device 100 may comprise peeling, wiping or any other suitable techniques.

The main section 1 and/or one or more of the flaps 2, 3 and 4 may comprise a plurality of through-apertures configured for evacuation of sweat, as the through-apertures 4b on the third flap 4 illustrated on FIG. 4.

The flaps 3 and 4 located on the side of the main section 1, namely the second flap 3 and the third flap 4 in the illustrative embodiment of FIG. 4, may comprise recesses in their respective central portions. The recesses are configured to let a proximal interphalangeal joint of the finger uncovered upon folding the flaps, thereby allowing the athlete to use his finger with a full range of motion while performing sport and wearing device 100.

As an example, recesses 310, 320 may be configured to, upon folding the flap on the dorsal side of the finger, define an area of the finger on its dorsal side that is not covered by the flaps 3 and 4. Therefore, the second and third flaps 3 and 4 may be configured to let the proximal interphalangeal joint of the hand 200 uncovered on the dorsal side.

In another embodiment, the second and third flaps 3 and 4 may comprise other recesses configured to let another area of the dorsal side of the finger uncovered, such as a distal interphalangeal joint of the finger. In another embodiment, the second and third flaps 3 and 4 may comprise other recesses configured to let the distal interphalangeal joint and/or the proximal interphalangeal joint of the finger uncovered.

In the same or another embodiment, one or more of the recesses 310 and 320 may define complete separations between two regions of a same flaps 3 or 4, each of the one or more recesses 310 or 320 thereby splitting the flap 3 or 4 into two independent flaps, the two independent flaps being independently extending from the main section 1 of the foldable substrate 610.

FIG. 5 is an image of an athlete's hand wearing three devices 100 on three different fingers in accordance with one embodiment of the present technology. In the illustrative embodiment of FIG. 5, proximal interphalangeal joints 410, 420 and 430 are left uncovered by the flaps 3′ and 4′. The flaps 2 (FIG. 4) of the devices 100 are hidden from view on FIG. 5, being partially covered by the flaps 3′ and 4′.

FIG. 6 is an image of the first flap of the device in accordance with one embodiment of the present technology. The first flap 2 may comprise a first section 2a and a second section 2b, the second section 2b being located between a top end of the main section 1 of the foldable substrate and the first section 2a of the first flap 2. As described hereinbefore, the first flap 2 is extending longitudinally and is configured to be folded around a tip of the finger. Therefore, upon folding the first flap 2, the first section 2a covers an area of the dorsal side of the finger and the second section 2b covers the tip of the finger. A lateral size of the first section 2a may be wider than a lateral size of the second section 2b of the first flap 2. This difference in the lateral size may be configured to prevent any undesirable chunks of matter and/or plies from appearing at the tip of the finger that may results in loss of sensitivity and/or loss of dexterity upon folding the first flap 2 on the finger.

FIGS. 7a, 7b and 7c show additional details of the device 100 in accordance with embodiments of the present technology. The device is worn on the index of the hand 200. In the illustrative embodiment of FIGS. 7a, 7b and 7c, the proximal interphalangeal joint 420 is left uncovered by the flap 3 and flap 4 folded around the finger, so not to impede with folding of the finger.

FIGS. 8a, 8b and 8c show the athlete's hand 200 wearing devices 100 in accordance with embodiments of the present technology. Three devices 100 are depicted on FIG. 8A, each of the three devices 100 covering one finger of the athlete's hand 200. As illustrated on FIG. 8A, each device 100 may comprise one or more regions 810 defining a shape or a pattern in the textured material configured to provide increased grip strength at desired locations of the foldable substrate 610. In opposition to FIG. 4, the device 100 may be asymmetrical. Indeed, FIG. 8b depicted a rear side of the athlete's hand showing asymmetric flaps of the device 100. A shape of the flaps may be configured to leave the flaps uncovered upon folding said flaps around the finger of the athlete's hand 200 as depicted in FIG. 8b. The devices 100 may cover a different number of phalanges as illustrated on FIG. 8c. Indeed, a first device 100 covering the index may cover only two phalanges of said index while a second device 100 covering the small finger of the athlete's hand may cover three phalanges of said finger. A number of phalanges covered by the device 100 is not a limitative aspect. The device 100 may be segmented into a plurality of sub-devices, where each sub-device is configured to cover on phalanx of a finger of the athlete's hand 200.

Those of ordinary skill in the art will realize that the description of the device 100 for improving hand grip are illustrative only and are not intended to be in any way limiting. Other embodiments will readily suggest themselves to such persons with ordinary skill in the art having the benefit of the present disclosure. Furthermore, the disclosed device may be customized to offer valuable solutions to existing needs and problems related to the lack of grip that athletes may experience and to the loss of tactile sensitivity that athletes wish to avoid. In the interest of clarity, not all of the routine features of the implementations of the device are shown and described. In particular, combinations of features are not limited to those presented in the foregoing description as combinations of elements listed in the appended claims form an integral part of the present disclosure.
