Connecting structure for a striking plate of a golf club head

Abstract

A golf club head includes a golf club head body, a ring, and a striking plate. The golf club head body includes a recession in a side thereof, the recession including a shoulder on an inner peripheral edge thereof. The ring is mounted on the shoulder of the golf club head body. The striking plate is mounted in the recession of the golf club head body and securely engaged with the ring, with the ring supporting a rear side of the striking plate. The striking plate and the golf club head body have a relatively small contact area therebetween to thereby reduce an amount of the striking stress of the striking plate absorbed by the golf club head body, thereby assuring high deformability of the striking plate.

1 . A golf club head comprising: 
 a golf club head body including a recession in a side thereof, the recession including a shoulder on an inner peripheral edge thereof, the shoulder further including at least one annular groove;    at least one ring mounted in the annular groove of the shoulder of the golf club body head; and    a striking plate mounted in the recession of the golf club head body so that the ring sandwiched in-between the striking plate and the shoulder of the golf club head body, the striking plate being securely engaged with the ring, with the ring supporting a rear side of the striking plate.    
   
   
       2 . The golf club head as claimed in  claim 1 , wherein the ring is made of a material having a Young's modulus smaller than 3×10 7  psi.  
   
   
       3 . The golf club head as claimed in  claim 2 , wherein the material of the ring is one of titanium, brass, bronze, aluminum, magnesium, and wood.  
   
   
       4 . The golf club head as claimed in  claim 1 , wherein the recession of the golf club head body further includes a flange on an outer peripheral edge thereof, the striking plate including a stepped portion, the flange being pressed to form a filling material for engaging with the stepped portion of the striking plate, thereby engaging the striking plate with the golf club head body.  
   
   
       5 . (Cancelled)  
   
   
       6 . The golf club head as claimed in  claim 1 , wherein the annular groove includes a plurality of notches in at least one of two opposed annularly extending corner portions thereof, the notches receiving deformed portion of the ring during a pressing procedure, thereby reducing a contact area between the striking plate and the shoulder of the golf club head body.  
   
   
       7 . The golf club head as claimed in  claim 1 , wherein the striking plate is supported by the ring, forming a gap between the shoulder of the gold club head and the striking plate.  
   
   
       8 . The golf club head as claimed in  claim 7 , further including a filling layer filled in the gap.  
   
   
       9 . The golf club head as claimed in  claim 8 , wherein the filling layer is formed as a result of hardening of a photocuring resin.  
   
   
       10 . The golf club head as claimed in  claim 9 , wherein the photocuring resin is a resin that hardens under radiation with one of visible lights and ultraviolet rays.  
   
   
       11 . The golf club head as claimed in  claim 1 , wherein the ring includes a base portion and an annular protrusion on a side of the base, the striking plate being mounted inside the annular protrusion and supported by the base portion of the ring when the striking plate and the ring are engaged in the golf club head body.  
   
   
       12 . The golf club head as claimed in  claim 1 , wherein the striking plate is made of a material having a Young's modulus smaller than 3×10 7  psi.  
   
   
       13 . The golf club head as claimed in  claim 1 , wherein the striking plate is made of one of titanium alloy, stainless steel, and special steel.  
   
   
       14 . The golf club as claimed in  claim 1 , wherein the golf club head body is made of a material having a Young's modulus greater than 2×10 7  psi.  
   
   
       15 . The golf club head as claimed in  claim 1 , wherein the golf club head body is made of one of stainless steel, carbon steel, alloy steel, and Fe—Mn—Al alloy.
