Golf club

Abstract

A golf club which comprises a head which is less deformable by the heat in welding. Separate reinforcing members 12 and 13 are provided on inner surface of a front edge 8 A of a crown shell 8. Thus, the front edge 8 A side is thickened and then the upper edge 4 A of the face shell 4 is joined to the front edge 8 A of the crown shell 8, by welding. The front edge 8 A of the crown shell 8 is formed with a plurality of projections 11 which are anchored by the upper edge 4 A of the face shell 4. front edge 8 A of the crown shell 8 is thickened by adding the thickness of the reinforcing members 12, 13 to the thickness of crown shell 8 itself. Thus, thermal deformation and the sinking of the front edge 8 A at the time of welding can be prevented, thus enabling the upper edge 4 A to be joined to the front edge 8 A as designed.

What is claimed:  
     
         1 . A golf club comprising: 
 a head formed by joining a plurality of separate shells one another, said separate shells including a first separate shell and a second separate shell;    a shaft connected to said head; and    a reinforcing means provided for reinforcing joint strength between said first separate shell and second separate shell, said reinforcing means being provided in a peripheral portion of at least said first separate shell.    
     
     
         2 . A golf club according to  claim 1 , wherein said peripheral portion of said first separate shell is thickened partially or entirely.  
     
     
         3 . A golf club according to  claim 1 , wherein said reinforcing means is a separate reinforcing member which is partially or entirely provided on an inner surface of said peripheral portion of said first separate shell, so that it is thickened.  
     
     
         4 . A golf club according to  claim 3 , wherein said seperate reinforcing member protrudes from an end of said first separate shell.  
     
     
         5 . A golf club according to  claim 1 , wherein a plurality of projections are provided on an end of at least said first separate shell so that said projections are anchored by an end of said second separate shell.  
     
     
         6 . A golf club according to  claim 1 , wherein cladding is partially or entirely provided on an inner surface of said first separate shell.  
     
     
         7 . A golf club according to  claim 1 , wherein said head is of a wood type.  
     
     
         8 . A golf club according to  claim 5 , wherein said projections protrude by a length which is less than or at most equal to a thickness of said second separate shell.  
     
     
         9 . A golf club according to  claim 7 , wherein a clearance is formed between an upper edge of a face shell and a front edge of a crown shell, while a weld bead is provided in the clearance.
