Shock-absorbent golf club handle structure
The present invention provides a shock-absorbent golf club handle structure, which includes a rubber bottom layer that is wrapped and fastened onto an end of a metallic golf club, and an outer surface layer that is mounted on an outer surface of the rubber bottom layer. Through the plurality of ring grooves formed on an outer end surface of the rubber bottom layer, isolated spaces are formed on the handle, when combining and wrapping the rubber bottom layer to the outer surface layer, thereby absorbing the shock produced during pitching and dampening the shock perceived by one's hand during pitching.
1. Field of the Invention
The present invention relates to a shock-absorbent golf club handle structure, particularly to a shock-absorbent golf club handle structure that is capable of dampening the shock to one's hand during golf pitching and maintaining the firmness when gripping the handle.
2. The Prior Arts
A conventional golf club handle structure primarily includes a rubber sleeve 1, which is directly wrapped and fastened onto an end of a metallic golf club. As the shock produced by pitching is transmitted to one's hand via the rubber sleeve 1, the hardness of materials for the rubber sleeve 1 is generally adjusted in order to overcome the shock produced when pitching the golf ball. However, the shock-absorbing effects of soft rubber sleeves are relatively limited. Moreover, they lower the sense of hand gripping, thus affecting pitching. As a result, improvement is required for the said conventional golf club handle.
According to another conventional rubber sleeve structure (shown in
The primary object of the present invention is to provide a shock-absorbent golf club handle structure, which is wrapped and fastened onto an end of a metallic golf club. The gold club handle structure includes a rubber bottom layer and an outer surface layer, wherein the rubber bottom layer is a suitably thick rubber layer, having a plurality of ring grooves formed on an outer end surface thereof and an inner surface of the rubber bottom layer wrapped and fastened onto an external rim of an end of the metallic golf club. On the other hand, the outer surface layer is a suitably thick rubber layer that is wrapped and fastened onto an outer surface of the rubber bottom layer. Finally, the handle structure is formed by combining and wrapping the rubber bottom layer to the outer surface layer. In this way, the plurality of ring grooves formed on the outer surface face of the rubber bottom layer is exactly positioned in the center of a layer formed by the handle, thereby forming ring-shaped isolated spaces. The shock produced by pitching will first be absorbed from the bottom layer, thus dampening the shock partially. Then, through the isolation created by the ring-shaped shock-absorbent spaces, the magnitude of the shock is further dampened, making the shock become minimized, such that the force perceived by one's hand becomes insignificant, thereby stabilizing the effects of pitching.
In other words, the primary object of the present invention is to provide a shock-absorbent golf club handle structure that subjects one's hand to a dampened shock level.
Another object of the present invention is to provide a shock-absorbent golf club handle structure that is capable of enhancing the sense of hand gripping.
The present invention will be apparent to those skilled in the art by reading the following detailed description of a preferred embodiment thereof, with reference to the attached drawings, in which:

Finally, the handle structure is formed by combining and wrapping the rubber bottom layer 30 to the outer surface layer 31, such that an opening of each of the plurality of ring grooves 310 is configured into a ring-shaped space by sealing an inner edge of the outer surface layer 31. In this way, each of the ring-shaped spaces is exactly positioned in the center of a layer formed by the handle. In addition, an upper cover 4 is wrapped and fastened onto a structure formed by wrapping the rubber bottom layer 30 to the outer surface layer 31. Then a fixed column 40 protruding from the upper cover 4 is positioned on a hollow structure of the metallic golf club 3, thereby fastening the handle to an end of the metallic golf club 3.
