Description
Description
1. Technical Field
This invention relates generally to a method and a system or device for providing a secure, resilient gripping surface on a bar, and more particularly relates to a resilient gripping pad which is easily wrapped or secured to a bar, such as a weightlifting bar, to provide a secure hand gripping surface on the bar, and to a method of providing an easily adjustable and removable secure resilient gripping surface on a bar.
2. Background of the Invention
Maintaining a secure comfortable grip is extremely important when operating or using various hand held apparatuses. For example, a secure grip is particularly important when using weightlifting equipment, such as a weightlifting bar or dumbbells. A secure grip on the weightlifting bar or the handle of the dumbbell can facilitate the use of greater weight, or increase the number of repetitions made during a particular exercise. Additionally, a secure grip is necessary to avoid accidentally dropping the weightlifting bar or dumbbell, which could result in injury to the user or others, or damage to the exercise equipment.
One method used by weightlifters to provide a secure grip is to coat their hands with rosin. This will make the weightlifter's hands sticky and allow the weightlifter to grip the bar without slipping. However, rosin has a tendency to build up on the weightlifting equipment which necessitates periodically cleaning the equipment to remove the built-up rosin.
Weightlifting gloves are also used by weightlifters to provide a more secure grip on the weightlifting bar. Some gloves are padded to provide a limited amount cushioning in the palm area. However, use of weightlifting gloves increases sweating of the hands during exercising, which permeates the gloves. When the sweat dries, the gloves can become stiff and useless.
Another method used to provide a secure grip is to add a rough textured surface on the weightlifting bar. However, a rough textured surface can cause blistering or abrasions on the hands.
Some weightlifting equipment, such as the Soloflex.RTM. dumbbell, include a cushioned surface permanently attached to the bar or handle area. However, placement of such a surface significantly increases the price of the weightlifting equipment. Further, the permanently placed surface cannot be removed and used on other weightlifting equipment or apparatuses.
Canvas strips have also been utilized to provide a secure grip on a weightlifting bar. A portion of a canvas strap, approximately 1.5 inches wide, is wrapped around the wrist, and the remaining portion is wrapped around the weightlifting bar. However, the strap must be unwrapped each time the user leaves the bar and rewrapped for the next use.
The present system and method are designed to overcome the problems associated with maintaining a secure resilient grip on a bar.
Summary of the Invention
The present invention is a method and system or device for providing a secure resilient gripping surface on a bar. The gripping surface is easily secured to the bar, and can be easily removed from the bar. Thus, the gripping surface can be readily adjusted to the proper position on a bar, and can be used on a variety of different bars.
The system for providing a secure resilient gripping surface on a bar comprises a flexible pad having a first outward gripping surface and an opposing second surface. The pad is wrapped completely around a first portion of the bar wherein at least a portion of the pad overlaps so that a portion of the second surface of the pad contacts and adheres to a portion of the first surface of the pad. The pad is removable from the first portion of the bar by unwrapping the gripping pad from the first portion of the bar. Preferably, the pad is somewhat stretched when wrapped around the bar.
The gripping pad is formed from a compressible and flexible material to provide a cushioned resilient gripping surface on the bar. Rubber is one preferred compressible and flexible material which can be used. A rubber gripping pad has a natural adhesion which enables a portion of the second surface of the pad to adhere to a portion of the first surface.
The pad can be formed to have a predetermined radius of curvature or domed shape wherein the first surface of the pad has a convex shape, and the second surface of the pad has a concave shape. This curvature will inhibit the gripping pad from unwrapping from the bar on its own.
When applied to a weightlifting bar, two gripping pads can be utilized, one for each hand.
The gripping pad of the present invention is not permanently secured to the bar. That is, the gripping pad can be simply removed by unwrapping the gripping pad from around the bar. This allows the gripping pad to be easily adjustable. It can be placed on one portion of a bar and then quickly removed and placed on a second portion of the bar. When used with weightlifting equipment, such as a weightlifting bar or a dumbbell, the disk-shaped weights do not have to be removed in order to secure or remove the gripping pad on the bar. Additionally, the same gripping pad can be used on a multitude of different bars.
The method of providing an easily adjustable and removable secure gripping surface on a bar comprises the steps of providing a bar, and a flexible resilient pad having a first outward gripping surface and an opposing second surface. The method further includes wrapping the pad around a first portion of the bar so that the pad overlaps and at least a portion of the second surface of the pad contacts and adheres to a portion of the first surface.
The wrapping step of the method can comprise slightly stretching the pad as the pad is being wrapped around the first portion of the bar. This will help ensure that the pad is maintained on the bar when in use.
The method may further include steps for adjusting the gripping pad. The gripping pad can be easily adjusted by unwrapping the pad from the first portion of the bar, and wrapping the pad around a second portion of the bar.
The method also may include providing a second gripping pad and wrapping the second pad around a second portion of the bar.
Further aspects of the invention are evident from the Detailed Description of the Preferred Embodiment, and FIGS. 1-3.

Detailed Description of the Preferred Embodiment
While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail a preferred embodiment of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiment illustrated.
The system of the present invention is designed to provide a secure resilient gripping surface on a bar which is grasped by a hand. The system is preferably utilized with weightlifting equipment, such as a weightlifting bar. However, it is readily apparent that other types of equipment can be utilized with this system.
In the preferred form, a flexible gripping pad is provided which is easily secured to a weightlifting bar by wrapping the gripping pad around a portion of the bar. The gripping pad will provide a comfortable resilient gripping surface which will enhance the ability to grip and utilize the weightlifting bar during various exercises with the bar.
FIGS. 1 and 2 disclose a gripping pad 10 for use in the present system. The gripping pad 10 has a generally rectangular first surface 12 and a generally rectangular second surface 14 opposing the first surface 12. The first and second surfaces 12, 14 respectively include a first end 16, a second end 18 opposing the first end 16, a first side 20, and an opposing second side 22. The first and second surfaces 12, 14 are separated by the thickness "t" of the gripping pad.
The gripping pad 10 is preferably formed from a compressible rubber material, which provides a comfortable secure grip when used on a bar as described below. The gripping pad 10 preferably has a thickness t of approximately 1/16 inches. Accordingly, the pad will not significantly increase the circumference of the bar.
The gripping pad 10 is easily secured to a portion of a weightlifting bar 24 (shown in FIG. 3) by positioning the first end 16 of the second surface 14 of the gripping pad 10 on the weightlifting bar 24, and wrapping the gripping pad 10 around the circumference of the weightlifting bar 24 so that the pad 10 overlaps itself and a portion of the second surface 14 contacts and adheres to a portion of the first outward surface 12. The gripping pad 10 is slightly stretched when wrapped around the weightlifting bar 24 to help ensure that the gripping pad 10 adheres to and remains secured to itself when in use.
The gripping pad 10 is easily removed by unwrapping the gripping pad 10 from the weightlifting bar 24. In this manner, the gripping pad can be easily adjusted to an appropriate position on the weightlifting bar 24.
In the preferred form, the second surface 14 of the gripping pad 10, which contacts the weightlifting bar 24 when wrapped around a portion of the bar 24, will have a natural adhesion. This will help ensure that the gripping pad 10 remains secured to the weightlifting bar 24 during use, and prevents the gripping pad from sliding along the length of the weightlifting bar 24.
FIG. 2 discloses another preferred feature which will help ensure that the gripping pad 10 is properly secured to the weightlifting bar 24. As shown in cross-section, the gripping pad 10 has a predetermined radius of curvature or domed shape which causes the second surface 14 to have a concave shape and the first surface 12 to have a convex shape. The radius of curvature will facilitate the gripping pad 10 to conform to the shape of the weightlifting bar 24 and will inhibit the gripping pad 10 from unwrapping on its own. Gripping pads having a radius of curvature can be manufactured by cutting generally rectangular sections from an inner tube type structure, such as a motorcycle inner tube.
When placed on the weightlifting bar 24, the first surface 12 is directed outwardly, and is contacted by the hand when gripped.
In one embodiment of the system, first and second gripping pads 10 are utilized with the weightlifting bar 24, one for each hand. In this form, the gripping pads 10 preferably have a length "l" of approximately 51/4 inches and a width "w" of approximately 43/4 inches. However, the gripping pads 10 can be formed so that the length more closely corresponds to the particular circumference of the weightlifting bar 24 being used.
The first gripping pad 10 is secured to a first portion of the weightlifting bar 24 by wrapping it around the first portion as described above. Similarly, the second gripping pad 10 is secured to a second portion of the weightlifting bar 24 in an identical manner. The first and second gripping pads 10 should be spaced apart on the weightlifting bar 24 a sufficient distance to provide the correct position of the hands for a particular exercise. The first and second gripping pads 10 can also be used on first and second dumbbell bars.
While a specific embodiment has been illustrated and described, numerous modifications come to mind without markedly departing from the spirit of the invention. The scope of protection is thus only intended to be limited by the scope of the accompanying claims.
