Abstract

A golf club head includes a body, a weight, and a positioning resilient member. The body includes an engaging seat having a perimeter wall and a perimeter groove defined in the perimeter wall. The weight is mounted in the engaging seat, and includes a main body having a perimeter wall with a plurality of latching grooves corresponding to the perimeter groove of the engaging seat. The positioning resilient member is initially mounted in the perimeter groove of the engaging seat prior to receiving the weight. The positioning resilient member includes at least one engaging point pressing against a perimeter bottom wall of the perimeter groove. The positioning resilient member is further engaged in the latching grooves of the weight to thereby resiliently retain the weight in the engaging seat when assembled.

Claims

1. A golf club head comprising:

a body including an engaging seat having a perimeter wall, a perimeter groove being defined in the perimeter wall;

a weight mounted in the engaging seat, the weight including a main body having a perimeter wall with a plurality of latching grooves corresponding to the perimeter groove of the engaging seat, wherein the main body of the weight includes a plurality of longitudinal unlatching holes extending from a first side of the main body through a second side of the main body, each said longitudinal unlatching hole being in communication with an associated one of the latching grooves of the main body, so that the combination of the longitudinal unlatching hole and the latching groove commonly forming a cruciform groove; and

a positioning resilient member mounted in the perimeter groove, the positioning resilient member including at least one engaging point pressing against a perimeter bottom wall of the perimeter groove of the engaging seat such that the positioning resilient member being received in the engaging seat, the positioning resilient member being further engaged in the latching grooves of the weight to thereby resiliently retain the weight in the engaging seat when assembled.

2. The golf club head as claimed in claim 1, wherein the engaging seat further including a bottom wall, and the golf club head further comprising a vibration-absorbing member mounted between the bottom wall of the engaging seat and the weight.

3. The golf club head as claimed in claim 1, wherein the engaging seat further includes a bottom wall and an extension extending longitudinally inward from the bottom wall, and the weight includes a shank extending from the main body, so that the shank is received in the extension of the engaging seat when assembled.

4. The golf club head as claimed in claim 1, wherein the extension of the engaging seat including an opened bottom end.

5. The golf club head as claimed in claim 1, wherein the extension of the engaging seat including a closed bottom end.

6. The golf club head as claimed in claim 5, further comprising a vibration-absorbing member mounted to the closed bottom end of the extension.

7. The golf club head as claimed in claim 1, wherein the shank of the weight including a plurality of sections having different lengths in varying weights.

8. The golf club head as claimed in claim 1, wherein the shank of the weight including a plurality of sections having different specific densities in varying weights.

9. The golf club head as claimed in claim 1, wherein the engaging seat including an opening that is polygonal, and wherein the main body of the weight having a shape corresponding to that of the opening of the engaging seat.

10. A golf club head comprising:

a body including an engaging seat having a perimeter wall, a perimeter groove being defined in the perimeter wall;

a weight mounted in the engaging seat, the weight including a main body having a perimeter wall with a plurality of latching grooves corresponding to the perimeter groove of the engaging seat;

a positioning resilient member mounted in the perimeter groove, the positioning resilient member including at least one engaging point pressing against a perimeter bottom wall of the perimeter groove of the engaging seat such that the positioning resilient member being received in the engaging seat, the positioning resilient member being further engaged in the latching grooves of the weight to thereby resiliently retain the weight in the engaging seat when assembled; and

an unlatching member including a plurality of unlatching rods, each said unlatching rod being inserted and slid into an associated one of the unlatching holes of the weight to expand the positioning resilient member radially outward, thereby allowing removal of the weight from the engaging seat.

11. The golf club head as claimed in claim 10, wherein each said unlatching rod includes an inclined face on a distal end thereof for pushing the positioning resilient member in disassembling operation.

12. The golf club head as claimed in claim 10, wherein the engaging seat including a bottom wall, and the golf club head further comprising a vibration-absorbing member mounted between the bottom wall of the engaging seat and the weight.

13. The golf club head as claimed in claim 10, wherein the engaging seat including a bottom wall and an extension extending longitudinally inward from the bottom wall, and the weight including a shank extending from the main body, so that the shank being received in the extension of the engaging seat when assembled.

14. The golf club head as claimed in claim 13, wherein the extension of the engaging seat including an opened bottom end.

15. The golf club head as claimed in claim 13, wherein the extension of the engaging seat including a closed bottom end.

16. The golf club head as claimed in claim 15, further comprising a vibration-absorbing member mounted to the closed bottom end of the extension.

17. The golf club bead as claimed in claim 13, wherein the shank of the weight including a plurality of sections having different lengths in varying weights.
