Iron clud head

Abstract

An iron club head includes a striking plate for striking a golf ball and a body. The body includes an elastically deformable thin wall. An opening is defined in a front side of the body and surrounded by the thin wall. The striking plate is bonded in the opening. The thin wall has a thickness smaller than that of the striking plate. When the iron club head hits a golf ball, a momentum of striking generated as a result of hitting the golf ball causes elastic deformation of the striking plate and the thin wall to increase an overall deformation of the iron club head.

1 . An iron club head comprising: 
 a striking plate adapted to strike a golf ball; and    a body including an elastically deformable thin wall, an opening being defined in a front side of the body and surrounded by the thin wall, the striking plate being bonded in the opening;    wherein the thin wall has a thickness smaller than that of the striking plate; and    wherein when the iron club head hits a golf ball, a momentum of striking generated as a result of hitting the golf ball causes elastic deformation of the striking plate and the thin wall to increase an overall deformation of the iron club head.    
   
   
       2 . The iron club head as claimed in  claim 1 , wherein the thickness of the thin wall is between 0.5 mm and 2.0 mm.  
   
   
       3 . The iron club head as claimed in  claim 1 , wherein the thickness of the striking plate is between 2.0 mm and 3.5 mm.  
   
   
       4 . The iron club head as claimed in  claim 1 , wherein the iron club head further comprises a weight member fixed to an inner face of the thin wall at a position behind a lower portion of the striking plate.  
   
   
       5 . The iron club head as claimed in  claim 4 , wherein a weight ratio of the body and the weight member is smaller than 5.5.  
   
   
       6 . The iron club head as claimed in  claim 1 , wherein the iron club head further comprises a weight member integrally formed on an inner face of the thin wall at a position behind a lower portion of the striking plate.  
   
   
       7 . The iron club head as claimed in  claim 6 , wherein a weight ratio of the body and the weight member is smaller than 5.5.  
   
   
       8 . The iron club head as claimed in  claim 1 , wherein the thin wall has a closed rear side.  
   
   
       9 . The iron club head as claimed in  claim 1 , wherein the thin wall has a rear side, the rear side of the thin wall having an opening in an upper section thereof.
