The present invention relates generally to the field of sports and sports equipment. Specifically, the present invention relates to a grip for handled sports equipment, for example, a baseball bat, a golf club and a hockey stick, that facilitates strength development through the natural movements of the sport.
Exercise grips for strength training of the hands and muscles in the arms are known in the art. For example, one can exercise and strengthen the hands with a compressible hand-grip strengthener, or spring-loaded compressible grips designed for a weightlifting bar to improve stability in the grip and strengthen the grip during a weightlifting session or designed to be placed on the handles of sports equipment during practice or training sessions. However, particularly, training for a sport that requires swinging handled equipment requires a high level of awareness or concentration in their use, including proper grip, stance, movement of the equipment and safety when in use, to develop one's strength and overall skill via the correct repetition of an action or activity.
The requirement of having to physically compress the grip in order to secure it to the handle or weightlifting bar focuses the concentration of the user onto compressing the grip and not to the actual motion the user is trying to replicate during a practice or training session and creates an added step or requirement for the grip to be functional. This is neither practical nor, more importantly, effective in developing strength during the normal repetition of an activity in a training exercise as it does not permit replication of the actual activity as normally required.
Such a situation can occur when using a spring-actuated jawed or sleeve-like grip designed to encircle the handle on sports equipment designed to be swung. For example, U.S. Pat. No. 8,128,542 B2 and U.S. Publication No. 2010/0197470 Al both disclose an exercise grip device that is a tube-like member with a lengthwise opening and a spring preformed to an open relaxed position. The exercise grip device is designed for use with a single hand and when placed around the handle, a user must compress and maintain compression in the closed position to keep the handle in place to strengthen the hand and arm. To exercise the other hand, a user must reposition the grip device so that the hand naturally grips it when properly placed on the handle.
Therefore, the prior art is deficient in a grip device for handled sports equipment that improve and strengthen the grip thereon. Particularly, the art is deficient in a grip that strengthens the grip of both hands simultaneously and strengthens the fingers, wrists, forearm, and upper arm muscles when the grip is placed on the handle without the necessity of constantly squeezing the grip beyond its relaxed configuration while swinging or otherwise moving the equipment. The present invention fulfills this longstanding need and desire in the art.
The present invention is directed to a grip device for a golf club. The grip device comprises a hollow member with a substantially cylindrical body comprising an outer surface, a bore that defines an inner surface therein and a length extending between the proximal open end and the distal open end, and a slit therethrough to the bore along the length of the hollow member. The outer surface and the inner surface are each with a perimeter that tapers along the length of the hollow member from the proximal open end to the distal open end to securely and removably receive a golf club handle therein.
The present invention is directed to a related grip device where the inner surface further comprises a plurality of nub-like protuberances disposed thereon adapted to grip the handle when placed thereon. The present invention is directed to another related grip device that further comprises a texture formed on the outer surface of the hollow member. The present invention is directed to yet another related grip device that further comprises a plurality of finger grooves formed on the outer surface of the hollow member.
The present invention also is directed to a two-handed grip device for a grip-end of a golf club. The two-handed grip device comprises a tubular sleeve having a length extending between a proximal open end and a distal open end and tapering along the length from the proximal open end to the distal open end. The tubular sleeve comprises an outer surface, a bore that defines an inner surface therein extending between the proximal open end and the distal open end and a slit through the outer surface to the bore from the proximal open end to the distal open end. The length of the tubular sleeve sufficient to accommodate both hands of a user gripped thereon when the grip device is placed on the golf club.
The present invention is directed to a related two-handed grip device where the inner surface further comprises a plurality of nub-like protuberances disposed thereon. The present invention is directed to another related two-handed grip device that further comprises a texture formed on the outer surface of the hollow member. The present invention is directed to yet another related two-handed grip device that further comprises a plurality of finger grooves formed on the outer surface of the hollow member.
The present invention is directed further to a two-handed grip device for a grip-end of a golf club. The two-handed grip device comprises a tubular sleeve having a length extending between a proximal open end and a distal open end and tapering along the length from the proximal open end to the distal open end. The tubular sleeve comprises an outer surface with a plurality of finger grooves formed thereon, a bore that defines an inner surface therein extending between the proximal open end and the distal open end and a slit through the outer surface to the bore from the proximal open end to the distal open end.

In a related embodiment there is provided herein two-handed grip device for a grip-end of a golf club, comprising a tubular sleeve having a length extending between a proximal open end and a distal open end and tapering along the length from the proximal open end to the distal open end, said tubular sleeve comprising an outer surface with a plurality of finger grooves formed thereon, a bore that defines an inner surface therein extending between the proximal open end and the distal open end and a slit through the outer surface to the bore from the proximal open end to the distal open end, the length of the tubular sleeve sufficient to accommodate both hands of a user gripped thereon when the grip device is placed on the golf club. In this embodiment the inner surface may be smooth. Further to this embodiment the inner surface may comprise a plurality of nub-like protuberances disposed thereon.
In both embodiments the proximal open end may have an outer diameter and an inner diameter at the bore as described supra and the distal open end may have an outer diameter and an inner diameter at the bore as described supra and the inner diameter at the distal open end is smaller than the outer diameter and the inner diameter at the proximal open end. Also the length may be about 7 inches to about 11.5 inches. In addition the proximal open end of the tubular sleeve, the distal open end of the tubular sleeve and the design of the tubular sleeve all may be as described supra.
Provided herein are grips, grip devices and handle grips adapted to be placed, affixed, applied or otherwise brought into contact with the handles of sports equipment, for example, but not limited to, those handles for which both hands are required to grip to play the sport or for which both hands may be utilized at some point while playing, for example, a tennis racquet. These grips are form-fitting and constructed or customized to firmly contact and engage the handle with the inner surface of the grip without a user having to apply an additional compressing force or squeezing force to the grip device to maintain its position and/or to obtain the benefit of strengthening the hands, fingers, wrists, forearms, and upper arms. The increase in diameter of the handle and concomitant increase in weight from the grip device or handle grip along its length requires a user to automatically grip the handle harder with both hands during practice of the sport to develop strength through the natural swing motion of the sport.
The grip devices and handle grips may have a length and outer diameter that, when disposed on or engaged with the handle, is sufficient to accommodate one or both hands in a grip appropriate for holding, swinging or otherwise moving the particular sports equipment. This is an improvement over and lessens or removes complexity from any grip strengthening device or system which requires separate devices for each hand. Alternatively, the grip devices and handle grips may be customized for a specific pair of hands.
The grips, grip devices and handle grips are designed or customized to conform to the varied and unique shapes of the handles on the sports equipment in a non-slipping relationship when the handle is received therein. This eliminates problems from a “one size fits all” approach. The grips, grip devices and handle grips are made from a material that does not compress when strongly gripped by a user. Such materials are known in the art.
The inner surface of the grip may be smooth. The friction between the entire surface area of the inner surface of the grips and the outer surface of the handle keeps the grip positioned on the handle. Alternatively, the inner surface may comprise a plurality of nub-like protuberances or nubs on the inner surface which keep the grip in position via friction. Although each nub has a smaller surface area with which to contact the handle, the evenly distributed nubs over the inner surface provides a plurality of dedicated areas of friction to keep the grip in position. The outer surface of the grip may have a textured pattern formed thereon that provides for a more secure grip for a user. A non-limiting example of a textured pattern or texture is a diamond pattern.
The grips have proximal and distal open ends. The surfaces across one or both of the open ends of the grip may be flat, inwardly beveled or flared depending on the shape of the handle and/or the shape of the proximal end of the handle. For example, a golf club flares toward the grip end of the handle and a baseball bat has a knob at the handle end.
The grip device or handle grip may be adapted or configured for the handle of a baseball bat. Generally, the grip device may be a hollow member with a substantially cylindrical body or may be a tubular sleeve a bore therein which defines or outlines an inner surface in the device. A slit is formed into the bore and along its length for easier insertion of the handle into the bore. The grip device may flex open along the slit to receive the handle, however, once positioned around the handle, the grip becomes form-fitting, is not compressible and is stabilized on the handle by friction. The grip device or handle grip may comprise a plurality of nub-like protuberances formed on or disposed over the inner surface. The nub-like protuberances increase the friction between the inner surface and the handle.
The device generally has a uniform outer diameter along the length. For example, the outer diameter may be about 1.5 inches to about 2.5 inches, or alternatively, 1.75 inches to 2.2 inches. The bore may a uniform diameter or inner diameter along its length. For example, the bore diameter may be about 0.8 inches to about 1 inch, for example, 0.82 inches or 26/32 inches, 0.91 inches or 29/32 inches or 0.97 inches or 31/32. Alternatively, the bore may comprise a proximal portion and a distal portion. The proximal portion has a larger diameter at the open end that tapers to a diameter equal to a uniform diameter in the distal portion. The larger diameter of the proximal portion is sufficient to accommodate the wider knob of the baseball bat handle. For example, at its widest, the proximal portion may have a diameter of greater than 1 inch to about 1.5 inches and the distal portion may have a uniform diameter of about 1 inch, for example, the 0.82 inches or 26/32 inches, 0.91 inches or 29/32 inches or 0.97 inches or 31/32 described herein.
The grip device or handle grip may be adapted for the handle of a golf club. The device may have a structure similar to that adapted for a baseball bat. The golf club handle grip generally may be a hollow member with a cylindrical body or a tubular sleeve each comprising a textured pattern thereon and a bore therein which defines or outlines an inner surface in the device. The handle grip may be a one-handed grip or a two-handed grip with a length sufficient to accommodate one or both hands in any of the ways in which a golf club may be held. The perimeter of the outer surface and of the inner surface tapers along the length of the grip from the proximal open end to the distal open end such that the diameters across the outer surface and the bore of the proximal open end is larger than the corresponding diameters at the distal open end. The larger proximal end diameters accommodate the shape of the wider proximal end of the grip end of the golf club. The one-handed or two handed handle grip also may comprise a slit disposed thereon and open to the bore as for the baseball bat handle grip. The one-handed or two handed handle grip when placed over the golf club grip is form-fitting and is held in place by friction as with the baseball handle grip and comprises a non-compressible material. Examples of such materials are, but not limited to, silicone, rubber, polyurethane, neoprene, or nitrile, or a combination thereof. The outer dimensions, inner or bore dimensions and the length of the handle grip are adjustable and/or customizable depending on the size and configuration of the golf club. A user may place one or two one-handed grips or a single two-handed grip on the golf club handle.
The length of the one-handed grip may be about 4 inches to about 6 inches and the length of the two-handed grip may be about 7 inches to about 11.5 inches, preferably about 9 inches to about 11 inches. The one-handed grip and the two handed grip have a larger outer diameter and a larger inner diameter at the proximal open end that tapers to a smaller outer diameter and smaller inner diameter at the open distal end. For example, at the proximal open ends of the one-handed and two-handed grips, the outer diameter across the open surface may be about 1.25 inches to about 2.15 inches and the inner diameter across the bore at the outer surface may be about 0.8 inches to about 1.25 inches. Correspondingly, at the distal open ends of the one-handed and two-handed grips, the outer diameter across the open surface may be about 1 inch to about 1.25 inches and the inner diameter across the bore at the outer surface may be about 0.60 inches to about 1 inch. One of ordinary skill in the art is well able to understand that for any specific lengths of the outer and inner diameters at the proximal open end, the corresponding specific lengths of the outer and inner diameters at the distal open end must be shorter, respectively.
The grip device or handle grip may be adapted for the handle of a hockey stick. The device may be a hollow member with a substantially cuboidal body made of the flexible, but non-compressible, material to accommodate the butt end of the shaft on the hockey stick. The top and bottom surfaces may comprise a textured pattern and with the sides form a bore therein. The handle grip also may optionally comprise a slit disposed thereon and open to the bore as for the baseball bat handle grip. The bore may be open along its entire length or, alternatively, may comprise a stop therein which forms a pocket in the bore. This provides additional securement of the handle grip on the butt end of the hockey stick shaft. The outer dimensions, inner dimensions and length of the handle grip including the dimensions of the pocket are adjustable and/or customizable depending on the size of the hockey stick.
Particularly, embodiments of the present invention are better illustrated with reference to the Figure(s), however, such reference is not meant to limit the present invention in any fashion. The embodiments and variations described in detail herein are to be interpreted by the appended claims and equivalents thereof.
