ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to a hand grip and more specifically to a hand grip for a handgun.
The present invention is specifically for use with a type of handgun commonly known as a revolver. It has been a trend in recent years to make revolvers lighter in weight and to this end many firearm manufacturers are offering many revolvers constructed from lightweight alloys and titanium. Substantial emphasis has been given to weight reduction in the gun itself, but the grip has been largely ignored. Conventional wisdom dictates that the revolver grip is to be held on the handle frame by screw or other attachment devices. The principal object of the present invention is to eliminate all unnecessary weight by eliminating all separate attachment hardware and maximizing the use of lightweight materials and construction.
The only prior art patent known to the inventor that uses an integral grip made from a resilient, flexible, synthetic plastic material is illustrated in Sniezak et al U.S. Pat No. 4,936,036. This handgrip still requires a pin

fitted through aligned bores in his grip and pin

serves to fasten the grip onto the handle of the handgun.
It is an object of the invention to provide a novel grip for a handgun that does not require any separate attachment hardware.
It is also an object of the invention to provide a novel grip for a handgun made entirely of lightweight plastic material.
It is another object of the invention to provide a novel grip for a handgun that has a U-shaped hard plastic molded core having an over molded layer of resilient plastic material.
It is a further object of the invention to provide a novel grip for a handgun that is economical to manufacture and market.
It is an additional object of the invention to provide a novel grip for a handgun that is easily and quickly attached or detached from the handle frame of a handgun such as a revolver.
SUMMARY OF THE INVENTION
The present invention is a grip for a revolver style handgun that has been molded from a stiff but resiliently flexible material. The grip has a U-shaped configuration such that the grip fits over the opposite ends of the stock pin extending outwardly from both lateral side walls of the handle frame. The U-shaped molded assembly has a front wall portion for engaging the front wall of a handgun handle and two sidewall portions extending rearwardly from the outer edges of the front wall portion for engaging the side walls of the handgun handle.
There is a groove on the inner surface of each of the side wall portions that extends substantially from its top end to its bottom end forming a track for receiving the opposite ends of the stock pin extending outwardly from the side walls of the handle frame of the handgun. A recess is formed in the bottom end of each of these grooves for capturing the respective opposite ends of the stock pin. The grip retains its position over the stock pin by the natural material tension of the grip exerting a clamping force toward the handle frame. The grip is further designed with compressible rubber bumpers in the loop area of the handle frame allowing the grip to be pre-loaded between the stock pin and the loop area in the fully installed position on the revolver. The pre-load prevents any shifting or rocking movement of the grip and compensates for any gun frame dimension variation.
