Golf club heads

Abstract

A golf club head includes a golf club head body, a striking plate mounted to the golf club head body, a hosel mounted to a side of the golf club head body, and a wrapping layer. The hosel includes a reduced section for reducing a weight of a hosel side of the golf club head, thereby shifting a center of gravity of the golf club head outwardly and downwardly and increasing an inertial momentum of the golf club head. The wrapping layer is made of a light material and wrapped around the reduced section of the hosel for improving structural strength of the hosel and for absorbing shock generated as a result of striking a golf ball.

1 . A golf club head, comprising: 
 a golf club head body;    a striking plate mounted to the golf club head body;    a hosel mounted to a side of the golf club head body, the hosel including a reduced section for reducing a weight of a hosel side of the golf club head, thereby shifting a center of gravity of the golf club head outwardly and downwardly and increasing an inertial momentum of the golf club head; and    a wrapping layer made of a light material and wrapped around the reduced section of the hosel for improving structural strength of the hosel and for absorbing shock generated as a result of striking a golf ball.    
   
   
       2 . The golf club head as claimed in  claim 1 , wherein the hosel further includes an engaging hole for engaging with a shaft.  
   
   
       3 . The golf club head as claimed in  claim 2 , wherein the hosel includes a top end distal to the golf club head body, a flange being formed on the top end of the hosel for improving bonding stability between the engaging hole of the hosel and the shaft.  
   
   
       4 . The golf club head as claimed in  claim 1 , wherein the reduced section of the hosel includes at least one protrusion on an outer periphery thereof for improving bonding stability between the reduced section and the wrapping layer.  
   
   
       5 . The golf club head as claimed in  claim 1 , wherein the reduced section of the hosel includes at least one recessed portion on an outer periphery thereof for improving bonding stability between the reduced section and the wrapping layer.  
   
   
       6 . The golf club head as claimed in  claim 1 , wherein the reduced section of the hosel includes a conic annular groove in a bottom edge wall thereof for improving bonding stability between the reduced section and the wrapping layer.  
   
   
       7 . The golf club head as claimed in  claim 1 , wherein the reduced section of the hosel extends to a joint area between the hosel and the striking plate.  
   
   
       8 . The golf club head as claimed in  claim 7 , wherein the reduced section of the hosel includes a conic annular groove in a bottom edge wall thereof for improving bonding stability between the reduced section and the wrapping layer.  
   
   
       9 . The golf club head as claimed in  claim 7 , wherein the hosel further includes an engaging hole for engaging with a shaft.  
   
   
       10 . The golf club head as claimed in  claim 9 , wherein the hosel includes a top end distal to the golf club head body, a flange being formed on the top end of the hosel for improving bonding stability between the engaging hole of the hosel and the shaft.  
   
   
       11 . The golf club head as claimed in  claim 10 , wherein the reduced section of the hosel includes at least one protrusion on an outer periphery thereof for improving bonding stability between the reduced section and the wrapping layer.  
   
   
       12 . The golf club head as claimed in  claim 10 , wherein the reduced section of the hosel includes at least one recessed portion on an outer periphery thereof for improving bonding stability between the reduced section and the wrapping layer.  
   
   
       13 . The golf club head as claimed in  claim 1 , wherein the hosel is formed by one of precision casting, casting, mechanical processing, press casting, forging, and injection molding.  
   
   
       14 . The golf club head as claimed in  claim 1 , wherein the hosel is engaged to the golf club head by means of section-by-section engagement.  
   
   
       15 . The golf club head as claimed in  claim 1 , wherein the wrapping layer wraps the reduced section of the hosel by one of heat pressing, press casting, and injection molding.
