Head of a golf club with high coefficient of restitution

Abstract

A head of a golf club is provided with a high coefficient of restitution. The head has a club head with an opening and a through hole opposite each other, a face panel securely mounted on the opening of the club head, a shaft securely mounted in the through hole of the club head, a shock-proof component mounted in the shaft, and an anti-impulse component mounted in the shaft and abutting the face panel. When hitting a golf, the face panel deforms concavely and shock waves are generated. Some of the shock waves are transmitted to the shaft via the through hole. With the shock-proof component, the shock waves transmitted via the through hole may be obstructed and not be absorbed by the anti-impulse component, which let all of the remaining shock waves on the face panel can be absorbed by the anti-impulse component thoroughly.

What is claimed is: 
     
         1 . A head of a golf club, the head comprising:
 a club head forming:
 an opening and a through hole on two opposite sides of the club head, respectively; 
   a face panel securely mounted on the opening of the club head;   a shaft securely mounted in the through hole of the club head; the shaft forming:
 a cavity including a bottom surface; 
   a shock-proof component mounted in the cavity of the shaft and comprising:
 a first surface abutting the bottom surface of the cavity; and 
 a second surface opposite the first surface; and 
   an anti-impulse component mounted in the cavity of the shaft and comprising:
 a third surface abutting the second surface of the shock-proof component; and 
 a fourth surface abutting an inner surface of the face panel. 
   
     
     
         2 . The head of a golf club as claimed in  claim 1 , wherein the anti-impulse component comprises:
 an anti-impulse recession formed on the third surface and concaved away from the shock-proof component.   
     
     
         3 . The head of a golf club as claimed in  claim 1 , wherein the shock-proof component comprises:
 a shock-proof recession formed on the second surface and concaved away from the anti-impulse component.   
     
     
         4 . The head of a golf club as claimed in  claim 1 , wherein one end of the shaft is screwed in the through hole of the club head. 
     
     
         5 . The head of a golf club as claimed in  claim 4 , wherein:
 the club head comprises:
 a first stepped surface in the through hole; and 
   the shaft has a flange abutting the first stepped surface.   
     
     
         6 . The head of a golf club as claimed in  claim 1 , wherein the shaft comprises:
 a column component comprising:
 a first end forming the cavity; and 
 a second end opposite the first end and fixed in the through hole of the club head; and 
   a weight adjusting component securely mounted in the column component.   
     
     
         7 . The head of a golf club as claimed in  claim 6 , wherein the weight adjusting component is screwed in the column component. 
     
     
         8 . The head of a golf club as claimed in  claim 1 , wherein the shaft comprises:
 a column component comprising:
 a first end forming the cavity; and 
 a second end opposite the first end and fixed in the through hole of the club head; and 
   a lead weight component mounted in the column component and being adjustable in location.   
     
     
         9 . The head of a golf club as claimed in  claim 8 , wherein the lead weight component is screwed in the column component.
