Golf club head of iron or wood type

Abstract

Head ( 1 ) of a golf club of the “wood” or “iron” type, having a wall forming the striking face ( 2 ), at least one wall adjacent the wall forming the striking face ( 2 ), namely in particular the wall of the sole ( 3 ), and which also comprises an elastic leaf ( 12 ) one end ( 13 ) of which is fixed to one of the walls ( 6 ) adjacent the wall forming the striking face ( 2 ), and the free other end ( 14 ) of which presses the preload against the back face ( 11 ) of the wall of the striking face ( 2 ).

1 . A head of a golf club of the “wood” or “iron” type, having a wall forming the striking face fixed to the rest of the head, at least one wall adjacent the wall forming the striking face, namely in particular the wall of the sole, and which also comprises an elastic leaf one end of which is fixed to one of the walls adjacent the wall forming the striking face, and the free other end presses the preload against the back face of the wall of the striking face.  
     
     
         2 . The golf club head as claimed in  claim 1 , wherein the elastic leaf if based on metal, on carbon or on glass composite.  
     
     
         3 . The golf club head as claimed in  claim 1 , wherein the elastic leaf is screwed, welded or bonded to the wall adjacent the wall forming the striking face.  
     
     
         4 . The golf club head as claimed in  claim 1 , wherein the free end of the elastic leaf is curved.  
     
     
         5 . The golf club head as claimed in  claim 1 , wherein the free end of the elastic leaf bears at, or in close proximity to, the sweet spot on the striking face.  
     
     
         6 . The golf club head as claimed in  claim 1 , wherein the elastic leaf is fixed to the wall of the sole.  
     
     
         7 . The golf club head as claimed in  claim 1 , and which is of the “wood” type.  
     
     
         8 . The golf club head as claimed in  claim 1 , and which is of the “iron” type.  
     
     
         9 . The golf club head as claimed in  claim 1 , and which comprises means for adjusting the force with which the leaf bears against the back face of the wall of the striking face.  
     
     
         10 . A method of manufacturing a golf club head as claimed in one of  claims 1  to  9 , and which consists: 
 first of all, before fitting the plate that forms the wall of the striking face on the head, in fixing one end of the metal leaf to a wall adjacent the wall of the striking face,  
 then secondly, in fitting the wall of the striking face, elastically deforming the metal leaf,  
 then in fixing the plate that forms the wall of the striking face to the head.  
 
     
     
         11 . The method of manufacturing a golf club head as claimed in one of  claims 1  to  9 , and which consists: 
 first of all, in producing a hollow head comprising the crown, lateral, rear walls and the wall comprising the striking face,  
 then secondly, in fitting the sole to which one end of the elastic leaf has already been fixed, on its interior wall, in such a way that the other end of the elastic leaf comes into contact with the wall of the striking face, experiencing a preload,  
 then finally in fixing the wall of the sole to the head.
