Striking plate for golf club head

Abstract

A golf club head includes a body and a striking plate mounted to the body. The body includes a coupling section at a front side thereof. The striking plate includes a striking portion for striking a golf ball and a perimeter wall extending rearward along a perimeter edge of the striking portion. The perimeter wall includes an end portion for coupling with the coupling section of the body. At least one reinforcing protrusion is formed on an inner face of the perimeter wall for improving vibration resistance of the body and the striking plate.

1 . A golf club head comprising: 
 a body comprising a coupling section at a front side thereof;    a striking plate mounted to the body, the striking plate comprising a striking portion for striking a golf ball and a perimeter wall extending rearward along a perimeter edge of the striking portion, the perimeter wall comprising an end portion for coupling with the coupling section of the body; and    at least one reinforcing protrusion formed on an inner face of the perimeter wall for improving vibration resistance of the body and the striking plate.    
   
   
       2 . The golf club head as claimed in  claim 1 , wherein said at least one reinforcing protrusion is located corresponding to at least one stress-concentrating area on the inner face of the perimeter wall.  
   
   
       3 . The golf club head as claimed in  claim 2 , wherein said at least one reinforcing protrusion is located on the inner face of a bottom portion of the perimeter wall and adjacent to a toe of the body.  
   
   
       4 . The golf club head as claimed in  claim 2 , wherein said at least one reinforcing protrusion is located on the inner face of a bottom portion of the perimeter wall and adjacent to a heel of the body.  
   
   
       5 . The golf club head as claimed in  claim 2 , wherein said at least one reinforcing protrusion is located on the inner face of a top portion of the perimeter wall and adjacent to a toe of the body.  
   
   
       6 . The golf club head as claimed in  claim 2 , wherein said at least one reinforcing protrusion is located on the inner face of a top portion of the perimeter wall and adjacent to a heel of the body.  
   
   
       7 . The golf club head as claimed in  claim 2 , wherein said at least one reinforcing protrusion is located on the inner face of a toe-side-portion of the perimeter wall.  
   
   
       8 . The golf club head as claimed in  claim 1 , wherein the perimeter wall has a width that varies along a perimeter length thereof.  
   
   
       9 . The golf club head as claimed in  claim 8 , wherein the width of the perimeter wall varies in one of continuous and discontinuous manner.  
   
   
       10 . The golf club head as clamed in  claim 8 , wherein variation of the width of the perimeter wall is positively related to a location of the center of gravity of the golf club head and a location of a sweet spot of the striking plate.  
   
   
       11 . The golf club head as claimed in  claim 8 , wherein the width of a bottom portion of the perimeter wall is greater than that of a top portion of the perimeter wall.  
   
   
       12 . The golf club head as claimed in  claim 8 , wherein the width of a top portion of the perimeter wall is greater than that of a bottom portion of the perimeter wall.  
   
   
       13 . The golf club head as claimed in  claim 8 , wherein the width of a toe portion of the perimeter wall is greater than that of a heel portion of the perimeter wall.  
   
   
       14 . The golf club head as claimed in  claim 8 , wherein the width of a heel portion of the perimeter wall is greater than that of a toe portion of the perimeter wall.  
   
   
       15 . The golf club head as claimed in  claim 1 , wherein the front side of the body further comprises a sidewall portion substantially orthogonal to the coupling section.  
   
   
       16 . The golf club head as claimed in  claim 15 , wherein the perimeter wall of the striking plate comprises a side opening adjacent to a heel of the body for coupling with the sidewall portion of the body.
