Abstract

A golf club head comprises a shock absorption device, which is made of a light shock absorbing material with a specific weight less than two, such as magnesium alloy. The shock absorption device is opening at a face portion and a bottom portion to form a crown, a toe, a heel, and a neck of the golf club head. A weight device, which is made of a wear-resisting material with a specific weight greater than six, such as stainless, is fixed to the shock absorption device at the bottom portion to form a bottom of the golf club head. An elastic device, which is made of a material with an elasticity greater than the shock absorption device and the weight device, such as titanium alloy, fixed to the shock absorption device at the face portion to form a face of the golf club head.

Claims

exact text as granted — not AI-modified
1 . A golf club head, comprising: 
 a shock absorption device made of a light shock absorbing material with a specific weight less than two, which is opening at a face portion and a bottom portion to form a crown, a toe, a heel, and a neck of the golf club head;    a weight device, which is made of a wear-resisting material with a specific weight greater than six, fixed to the shock absorption device at the bottom portion to form a bottom of the golf club head; and    an elastic device, which is made of a material with an elasticity greater than the shock absorption device and the weight device, fixed to the shock absorption device at the face portion to form a face of the golf club head.    
   
   
       2 . The golf club head as defined in  claim 1 , wherein the shock absorption device is made of magnesium alloy and is made by die casting.  
   
   
       3 . The golf club head as defined in  claim 1 , wherein the shock absorption device is bonded with a tube to form the neck.  
   
   
       4 . The golf club head as defined in  claim 1 , wherein the weight device  30  is made of stainless, ductile iron or maraging steel.  
   
   
       5 . The golf club head as defined in  claim 1 , wherein the elastic device is made of titanium alloy.  
   
   
       6 . The golf club head as defined in  claim 1 , wherein the shock absorption device and the weight device are provided with a slot and a plug member respectively for engagement.  
   
   
       7 . The golf club head as defined in  claim 1 , wherein the elastic device is engaged with the shock absorption device and the weight device, and an adhesive is added therebetween.
