Abstract

A golf club head includes a golf club head body, a striking plate mounted to the golf club head body, a hosel mounted to a side of the golf club head body, and a heel between the hosel and the striking plate. The heel includes a compartment for reducing a weight of the heel, thereby shifting a center of gravity of the golf club head toward a toe of the golf club head body and increasing an inertial moment of the golf club head. A filling material may be filled in the compartment for absorbing vibrations generated as a result of striking a golf ball.

Claims

1. A golf club head, comprising:

a golf club head body having a toe and an inner peripheral wall, the inner peripheral wall being along a portion of a circumference of the golf club head;

a striking plate mounted to a front side of the golf club head body, a rear cavity being an area surrounded by the toe, the strike plate, and the inner peripheral wall;

a hosel mounted to a side of the golf club head body, the hosel being adapted to engage with a shaft; and

a heel disposed between the hosel and the striking plate, the heel including a compartment for reducing a weight of the heel, thereby shifting a center of gravity of the golf club head toward the toe of the golf club head body, the compartment having an opening located in the rear cavity and on the inner peripheral wall to communicate the compartment with the rear cavity of the golf club head body.

2. The golf club head as claimed in claim 1, wherein the compartment of the heel are delimited by a plurality of wall sections having an identical wall thickness.

3. The golf club head as claimed in claim 1, further including a plurality of flanges formed on an inner periphery delimiting the compartment of the heel.

4. The golf club head as claimed in claim 1, further including a filling material received in the compartment of the heel for absorbing vibrations generated as a result of striking a golf ball.

5. The golf club head as claimed in claim 4, wherein the filling material is a damping material selected from a group consisting of rubbers, emulsions, foam materials, liquids, gels, and epoxy resins that are capable of absorbing vibrations.

6. The golf club head as claimed in claim 1, wherein the heel and the hosel are formed on the side of the golf club head body by one of precision casting, forging, integral formation, casting, mechanical processing, press casting, and injection molding.

7. The golf club head as claimed in claim 1, wherein the heel and the hosel are engaged to the side of the golf club head body by means of section-by-section engagement.

8. The golf club head as claimed in claim 1, wherein the golf club head body includes an engaging portion to which the striking plate is mounted.

9. The golf club head body as claimed in claim 8, wherein the engaging portion includes a space delimited by an inner periphery, the opening communicating with the space of the engaging portion.

10. The golf club head as claimed in claim 9, further including a filling material received in the compartment of the heel for absorbing vibrations generated as a result of striking a golf ball.

11. The golf club head as claimed in claim 10, wherein the filling material is a damping material selected from a group consisting of rubbers, emulsions, foam materials, liquids, gels, and epoxy resins that are capable of absorbing vibrations.

12. The golf club head as claimed in claim 3, further including a filling material received in the compartment of the heel for absorbing vibrations generated as a result of striking a golf ball.

13. The golf club head as claimed in claim 12, wherein the filling material is a damping material selected from a group consisting of rubbers, emulsions, foam materials, liquids, gels, and epoxy resins that are capable of absorbing vibrations.
