Golf club head having a brazed striking plate

Abstract

A golf club head includes a casing with a front open end to which a striking plate is attached through a layer of brazing material that is formed between a rear surface of the striking plate and a frontmost end face of the casing. One of the striking plate and the front open end of the casing has an extension part which projects outward in a direction away from the opening. The extension part forms a shoulder with one of the first and second outer peripheral faces. During a brazing process, the brazing material is positioned against the shoulder externally of a clearance between the rear surface and the frontmost end face and is then melted to flow into the clearance through a capillary action.

1 . A golf club head comprising: 
 a casing having a front open end defining an opening, said front open end having a frontmost end face and a first outer peripheral face extending rearwardly from said frontmost end face;    a striking plate attached to said front open end to cover said opening and including a rear surface confronting said frontmost end face, a front surface opposite to said rear surface, and a second outer peripheral face that extends forwardly from said rear surface to said front surface; and    a layer of brazing material bonding said rear surface to said frontmost end face and formed within a clearance between said rear surface and said frontmost end face,    one of said striking plate and said front open end having an extension part which projects outward in a direction away from said opening and along a plane of said layer of brazing material, said extension part forming a shoulder with one of said first and second outer peripheral faces, said shoulder being exterior to and immediately adjacent to said clearance,    whereby said shoulder is adapted to hold said brazing material during a brazing process.    
   
   
       2 . The golf club head as claimed in  claim 1 , wherein said striking plate has said extension part, said extension part forming said shoulder with said first outer peripheral face.  
   
   
       3 . The golf club head as claimed in  claim 1 , wherein said front open end of said casing has said extension part, said extension part forming said shoulder with said second outer peripheral face.  
   
   
       4 . The golf club head as claimed in  claim 1 , wherein said rear surface and said frontmost end face are provided with interlocking elements which interlock said rear surface and said frontmost end face.  
   
   
       5 . The golf club head as claimed in  claim 4 , wherein said interlocking elements include a projection formed on one of said rear surface and said frontmost end face, and a groove formed on the other one of said rear surface and said frontmost end face to engage said projection.  
   
   
       6 . The golf club head as claimed in  claim 5 , wherein said projection has a slanting face, said groove having a slanting face engaging said slanting face of said projection.
