Club head of a golf iron capable of changing its center of gravity

Abstract

The present invention discloses a club head of a golf iron capable of changing its center of gravity, and the club head includes a groove disposed on a blade at the back of a striking surface, a lightweight specific gravity member installed in the groove, so that the groove and the specific gravity member are integrally combined by thermal pressing. The specific gravity member is provided for tuning the center of gravity of the club head of the golf iron so as to give a better stability of striking and controlling a golf ball, and achieve the effects of identifying and decorating the appearance of the club head of the golf iron.

1 . A club head of a golf iron capable of changing its center of gravity, comprising a groove disposed at a blade at the back of a striking surface of said club head, and a specific gravity member disposed into said groove and integrally coupled with said groove by thermal pressing, such that said specific gravity member is used for tuning the center of gravity of said club head of said golf iron to achieve a stability for striking and controlling a golf ball.  
     
     
         2 . The club head of a golf iron capable of changing its center of gravity of  claim 1 , wherein said specific gravity member is made of a lightweight plastic material.  
     
     
         3 . The club head of a golf iron capable of changing its center of gravity of  claim 2 , wherein said specific gravity member is made of polyurethane elastomers (TPU).  
     
     
         4 . The club head of a golf iron capable of changing its center of gravity of  claim 2 , wherein said specific gravity member is made of carbon fibers.  
     
     
         5 . The club head of a golf iron capable of changing its center of gravity of  claim 2 , wherein said specific gravity member is made of ethylene propylene dien monomers (EPDM).  
     
     
         6 . The club head of a golf iron capable of changing its center of gravity of  claim 1 , wherein said specific gravity member is made by an injection molding and coupled with said groove of said club head of said golf iron.  
     
     
         7 . The club head of a golf iron capable of changing its center of gravity of  claim 6 , wherein said specific gravity member is made of an injection molding and attached onto said groove of said club head of said golf iron.
