DETAILED DESCRIPTION OF INVENTION

The above general description and the following detailed description are merely illustrative of the subject invention and additional modes, advantages and particulars of this invention will be readily suggested to those skilled in the art without departing from the spirit and scope of the invention.
The device subject of this disclosure relates to a hand grip that can be installed on exercise equipment such as dumbbells, weight bars, EZ curl bars or exercise machine handles. One advantage of the device (hereinafter “hand grips”) is that the hand grips increase the circumference of the device to be grasped and held by the user's hand. This opens the user's grip when exercising.
The increased circumference achieved from installation of the hand grips is advantageous. The increased circumference spreads the grip of the hand to a more open position. This causes the user to use more force to hold the exercise device without any change in the weight of the device. Exercising with the devices achieves greater finger, hand, and forearm strength with increased muscularity. The purpose of opening the hand grip is to fatigue the muscles in the fingers, hands, and forearms more quickly and more thoroughly than when compared to gripping a standard exercise bar (typically 1 inch diameter or 28 to 30 mm). The use of the hand grips will force the muscles in the fingers, hand and forearms to grow stronger and larger to adapt to the increased force required to grip the bar or handle. The hand grip subject of the invention forces the grip, forearm and biceps to work harder with no increase in the number exercise sets being performed, increase in weights or the time spent working out.
Another advantage of the hand grips is that they can be made of soft, pliable material such as a visco-elastic, urethane or close cell foam. The hand grips may provide a cushioned surface for the user's hand. The hand grip material is able to yield and form around the palm and fingers when squeezed while exercising. This creates a more secure grip as the user has an increased surface area to grip with his/her hand. The rubber like material of the hand grip yields as the user squeezes (grips) to hold onto the bar or handle. This forms a no slip bond with the handle and the bar. The hand grip both opens the grip of the hand and is squeezable.
The annulus and lengthwise split of the hand grip permits the device to fit over varying sized equipment. For example, the hand grip can be used with a 1 inch to 1¼ inch diameter bar.
For example, the hand grip facilitates a reverse curl grip with dumbbells. Starting with the dumbbells in a reverse curl grip, slowly reverse curl the dumbbells up and rotate the dumbbells 180 degrees to the finish at the top of the curl. On the negative portion of the repetition repeat the same motion down. The positive and negative portions of the repetition are to be done slowly and in complete control. This maneuver or exercise feels very awkward without the hand grip subject of the invention. The increased gripping area and resulting control makes this a great exercise.
The hand grip will be beneficial to persons involved in sports that require excellent hand and finger strength. Examples include rock climbing, martial arts, baseball, football, basketball, bodybuilding, tennis and golf. Another group that would benefit would be persons involved in highly demanding activities such as those serving in the United States Armed Forces, police officers, firemen, and emergency medical personnel.
In one embodiment, the hand grips may be manufactured using a plastic injection molding machine. The material used in manufacturing the hand grips may be a soft rubber like material. In a preferred embodiment, the hand grip includes 1 to 1⅛ inch outside diameter (OD) hole or annulus in the center. The annulus extends longitudinally from the small end to the wide end of the hand grip. The hand grip also has a split or opening on one side that allows the hand grip to be spread apart to fit over a standard 1″ OD exercise barbell, dumbbell handle, or exercise machine handle. It will be appreciated that the hand grip may be removed from the equipment when the user is finished and the hand grip placed on other equipment. The removal of the hand grip enhances sanitation of exercise equipment.
The hand grips are designed to be wider at one end, for example 2 inches in an outer diameter (first end) than the other end, for example 2½ inches at a second end. This forms a conical shape.
FIG. 1 illustrates an end view of the first end of the hand grip comprising an outer component 112 of a soft, pliable material such as a visco-elastic, urethane or close cell foam. Also illustrated is an inner annulus 117. The diameter of the annulus may remain relatively constant for the length of the device. See FIG. 2. The length of the hand grip may be 4½ inches. Other lengths are within the scope of the invention.
FIG. 2 illustrates a cross-sectional view of the device shown in FIG. 1. The outer diameter of the hand grip 110 expands from the first end 111 to the second end 112. FIG. 2 also illustrates the cross-sectional view of the device as shown from the second end (FIG. 3). In one example, the outer diameter of the first end is 2 inches and expands to 2½ inches at the second end. Note that in this example, the diameter of the annulus 117 remains constant at 1⅛ inches.
Also illustrated in FIG. 2 is the split or slit 115 that extends through the length and thickness of the hand grip 110 to the annulus 117. As explained elsewhere, this allows the device to be open longitudinally to be placed over a piece of exercise equipment such as a handle on a weight machine or a weight bar.
The hand grip is held in the grip of the user's hand. The wider hand grip end (second end) is held at the bottom of the user's palm, with the narrower end (first end) held against the thumb end of the palm. This design allows the bar or handle to be held more squarely or securely in the palm of the hand. This includes better balance and set straight. This is a more ergonomically correct position in the palm of the hand. The design also forces the fingers to be spread more open when contrasted with holding a bar or handle not using the grips.
FIG. 1 illustrates a top view (first end) of the hand grip showing a 2 inch outside diameter and the inner annulus 117 having a 1⅛ inch diameter.
FIG. 2 illustrates a cross sectional view of the hand holder 110 and the annulus 117. Also illustrated is the tapered shape of the device as it extends from a first end to the wider second end. Also illustrated is the side slit 115 used to open the conical shaped handle for placement on an exercise bar.
FIG. 3 illustrates the second end of the hand grip wherein the outside diameter is illustrated 2½ inches. The inner annulus 117 retains the same approximate 1 inch to 1⅛ inch diameter.
FIG. 4 illustrates the placement of the hand grips 110 on dumbbells 201. The hand grips are placed on the connecting bar 200. The bars have an approximate equal outer diameter than other exercise equipment. Note that the split 115 extending the length of the hand grip may be used to fit the hand grip on the bar.
FIG. 5 illustrates placement of the hand grips 110 on a bar bell 203. The grips are place at the hand hold position of the user.
FIG. 6 illustrates the placement of the hand grips 110 on an EZ curl bar 204.
FIG. 7 illustrates the hand holder 110 placed on a handle 207 of an exercise machine pulling device 205. Also illustrated is the rope of the pulling device.
FIG. 8 illustrates as side view of the hand grip 110, including the narrow first end 111 and the wider second end 113 including the side slit 115 for inserting the holder on the exercise equipment 200.
This specification is to be construed as illustrative only and is for the purpose of teaching those skilled in the art the manner of carrying out the invention. It is to be understood that the forms of the invention herein shown and described are to be taken as the presently preferred embodiments. As already stated, various changes may be made in the shape, size and arrangement of components or adjustments made in the steps of the method without departing from the scope of this invention. For example, equivalent elements may be substituted for those illustrated and described herein and certain features of the invention may be utilized independently of the use of other features, all as would be apparent to one skilled in the art after having the benefit of this description of the invention.
Further modifications and alternative embodiments of this invention will be apparent to those skilled in the art in view of this specification.
