Golf club head with adjustable vibration-absorbing capacity

Abstract

A golf club head includes a body, a striking plate engaged with the body and including a front side for striking a golf ball and a rear side, at least one vibration-receiving member made of an elastomeric material, and at least one adjusting member. At least one compartment is defined in a rear side of the body and is delimited by the rear side of the striking plate. The vibration-absorbing member is mounted in the compartment and in contact with a portion of the rear side of the striking plate. The adjusting member is adjustably mounted in the compartment to adjust a pressing force exerting on the rear side of the striking plate by the vibration-absorbing member and to adjust a compressed amount of the vibration-absorbing member, thereby effectively absorbing residual vibrations and avoiding loss of momentum.

1 . A golf club head comprising: 
 a body, a striking plate being engaged with the body and including a front side for striking a golf ball and a rear side, the body including at least one compartment in a rear side of the body and being delimited by the rear side of the striking plate;    at least one vibration-receiving member made of an elastomeric material and mounted in said at least one compartment, said at least one vibration-absorbing material being in contact with a portion of the rear side of the striking plate; and    at least one adjusting member mounted in said at least one compartment, said at least one adjusting member being adjustable to adjust a pressing force exerting on the rear side of the striking plate by said at least one vibration-absorbing member and to adjust a compressed amount of said at least one vibration-absorbing member, thereby effectively absorbing residual vibrations and avoiding loss of momentum.    
   
   
       2 . The golf club head as claimed in  claim 1 , wherein said at least one adjusting member is a screw having an outer threading, an inner periphery delimiting said at least one compartment including an inner threading for threadedly engaging with the outer threading of the screw.  
   
   
       3 . The golf club head as claimed in  claim 2 , wherein said at least one adjusting member further includes a slot for engaging with a tool for driving said at least one adjusting member.  
   
   
       4 . The golf club head as claimed in  claim 1 , wherein said at least one vibration-absorbing member is bonded in said at least one compartment.  
   
   
       5 . The golf club head as claimed in  claim 1 , wherein said at least one vibration-absorbing member is slidably received in said at least one compartment.  
   
   
       6 . The golf club head as claimed in  claim 1 , wherein said at least one compartment and said at least one vibration-absorbing member are located in a location opposite to a sweet spot of the striking plate.  
   
   
       7 . The golf club head as claimed in  claim 1 , said at least one compartment and said at least one vibration-absorbing member are located in a location opposite to a residual vibration concentrating area of the striking plate.  
   
   
       8 . The golf club head as claimed in  claim 1 , wherein said at least one vibration-absorbing member includes a bladder defining a gas chamber, the gas chamber being filled with at least a gas to provide said at least one vibration-absorbing member with compressibility.  
   
   
       9 . The golf club head as claimed in  claim 8 , wherein the gas chamber in the bladder has a pressure not lower than atmosphere.  
   
   
       10 . The golf club head as claimed in  claim 8 , wherein the gas chamber further contains a liquid.  
   
   
       11 . The golf club head as claimed in  claim 10 , wherein the liquid is selected from the group including water, oil, gel-like fluid, non-corrosive water solution, organic solution, mixed solution, and viscous solution.  
   
   
       12 . The golf club head as claimed in  claim 1 , wherein said at least one vibration-absorbing member is solid and has compressibility.  
   
   
       13 . The golf club head as claimed in  claim 1 , wherein said at least one vibration-absorbing member and said at least one adjusting member are integrally formed with each other.  
   
   
       14 . The golf club head as claimed in  claim 1 , wherein the body is an iron club head body including a back cavity that exposes the rear side of the striking plate.  
   
   
       15 . The golf club head as claimed in  claim 14 , wherein the back cavity is communicated with said at least one compartment.  
   
   
       16 . The golf club head as claimed in  claim 1 , wherein the elastomeric material of the bladder is selected from the group including rubber, polyurethane, thermoplastic elastomers, and high-molecular elastomeric resins.  
   
   
       17 . The golf club head as claimed in  claim 1 , wherein the elastomeric material has a hardness between Shore A 10 and Shore D 30.
