Golf club head having a high-degree elastically deformable structure

Abstract

A golf club head includes a golf club head body, an elastically deformable thin layer, a striking plate and a club weight portion. The golf club head body includes a crown portion, a toe-side wall portion, a sole portion and a heel-side wall portion. The elastically deformable thin layer is provided on the golf club head body and arranged between the toe-side wall portion and the heel-side wall portion. The elastically deformable thin layer has a thickness thinner than that of other portions of the golf club head body. Mounted on a front portion of the striking plate is the striking plate along which the elastically deformable thin layer has a direction of extension so as to absorb a striking stress transmitted from the striking plate. The club weight portion is arranged on the golf club head body to adjust the center of gravity and the moment of inertia.

1 . A golf club head having a high-degree elastically deformable structure, comprising: 
 a golf club head body including a front portion and a crown portion, the golf club head body having an inner surface delimiting an inner space, and an outer surface opposite to the inner surface;    an elastically deformable thin layer being selectively disposed on at least one of the inner surface and the outer surface of the golf club head body, and being located on the crown portion, said elastically deformable thin layer having a thickness less than that of other portion of the golf club head body; and    a striking plate disposed on the front portion of the golf club head body, the of the golf club head body having a predetermined distance spaced from the striking plate.    
   
   
       2 . The golf club head having the high-degree elastically deformable structure as defined in  claim 1 , wherein the golf club head body further includes a toe-side wall portion and a heel-side wall portion such that the elastically deformable thin layer is continuously extended on the crown portion and between the toe-side wall portion and the heel-side wall portion.  
   
   
       3 . The golf club head having the high-degree elastically deformable structure as defined in  claim 1 , wherein the golf club head body further includes a club weight portion to receive a club weight member, the club weight portion is arranged at a predetermined position according to that of the elastically deformable thin layer.  
   
   
       4 . The golf club head having the high-degree elastically deformable structure as defined in  claim 1 , wherein golf club head body further includes a club weight portion to receive a club weight member, a size of the club weight member is selected according to a size of the elastically deformable thin layer.  
   
   
       5 . The golf club head having the high-degree elastically deformable structure as defined in  claim 1 , wherein the golf club head body further includes a toe-side wall portion and a heel-side wall portion such that the elastically deformable thin layer is continuously extended from the toe-side wall portion through the crown portion to the heel-side wall portion of the golf club head body.  
   
   
       6 . The golf club head having the high-degree elastically deformable structure as defined in  claim 1 , wherein the golf club head body further includes a toe-side wall portion, a sole portion and a heel-side wall portion such that the elastically deformable thin layer is continuously extended along the toe-side wall portion, the crown portion, the heel-side wall portion and the sole portion of the golf club head body.  
   
   
       7 . The golf club head having the high-degree elastically deformable structure as defined in  claim 1 , wherein located between the inner surfaces of the golf club head body and the elastically deformable thin layer is a connection portion which is constructed from a stepped portion.  
   
   
       8 . The golf club head having the high-degree elastically deformable structure as defined in  claim 1 , wherein located between the inner surfaces of the golf club head body and the elastically deformable thin layer is a connection portion which is constructed from a inclined portion.  
   
   
       9 . The golf club head having the high-degree elastically deformable structure as defined in  claim 1 , wherein located between the outer surfaces of the golf club head body and the elastically deformable thin layer is a connection portion which is constructed from a stepped portion.  
   
   
       10 . The golf club head having the high-degree elastically deformable structure as defined in  claim 1 , wherein located between the outer surfaces of the golf club head body and the elastically deformable thin layer is a connection portion which is constructed from a inclined portion.
