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.

Claims

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.
