Shock-absorbent golf club handle structure

Abstract

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.

       3 . A shock-absorbing golf club handle structure wrapped and fastened onto an end of a metallic golf club comprising:
 a) a rubber bottom layer having:
 i) a plurality of ring grooves located around an exterior surface thereof and located on an end portion of the rubber bottom layer; and 
 ii) an inner adhesive layer coated on an interior surface thereof and connecting the rubber bottom layer to the metallic golf club; and 
   b) an outer surface layer having outer adhesive layer directly located on the exterior surface of the rubber bottom layer, the outer surface layer sealing an open end of the plurality of ring grooves,   wherein the plurality of ring grooves are spaced apart from the interior surface of the rubber bottom layer and an exterior surface of the outer surface layer.   
   
   
       4 . The shock-absorbing golf club handle structure according to  claim 3 , wherein the outer surface layer has a thickness between 1.5 mm and 2.0 mm. 
   
   
       5 . The shock-absorbing golf club handle structure according to  claim 3 , wherein the plurality of ring grooves are equally spaced between the interior surface of the rubber bottom layer and the exterior surface of the outer surface layer.
