Abstract

A method of forming a golf club head includes providing a body having an end portion (e.g., a heel end or a toe end of the club head) wherein the body end portion includes a lower surface and a boss extending therefrom. The method comprises providing a weight having a top surface and a cavity configured to receive the boss, and inserting the boss on the body into the cavity in the weight by rotating the weight such that the boss interlocks with the cavity and so that at least a portion of the top surface of the weight contacts at least a portion of the lower surface of the body end portion. The weight further includes a protrusion having a concave surface and the body has a corresponding convex surface. The weight is rotated about an axis extending through the body such that the concave surface of the weight bears on the convex surface of the body

Claims

1. A method of forming a golf club head, said method comprising:

providing a body having an end portion, wherein said body end portion includes a lower surface and a boss extending therefrom;

providing a weight having a top surface and a cavity configured to receive said boss; and

inserting said boss into said cavity by rotating said weight such that said boss interlocks with said cavity and so that at least a portion of said top surface of said weight contacts at least a portion of said lower surface of said body end portion.

2. The method of claim 1, further including securing said weight to said body end portion.

3. The method of claim 2, wherein said securing step includes fastening said weight to said body using a screw inserted through said weight into said body.

4. The method of claim 1, wherein said weight further includes a protrusion having a concave surface and wherein said body has a corresponding convex surface, and said rotating step including rotating said weight about an axis extending through said body such that said concave surface of said weight bears on said convex surface of said body.

5. The method of claim 1, wherein said end portion of said body corresponds to a heel end of said body.

6. The method of claim 1, wherein said end portion of said body corresponds to a toe end of said body.

7. The method of claim 1, wherein said body includes another end portion, and wherein said method further includes providing another weight configured to interlock with said another end of said body.

8. The method of claim 1, wherein said body and said weight each include a front surface, and wherein said rotating step includes rotating said weight such that said front surface of said weight is substantially flush with said front surface of said body thereby forming a striking face on said golf club head.

9. The method of claim 1, wherein said body includes a sole, said weight includes a bottom surface, and wherein said rotating step includes rotating said weight such that said bottom surface of said weight is substantially flush with said sole.

10. A golf club head comprising:

a body having an end portion, said body end portion including a lower surface and a boss extending therefrom; and

a weight having a top surface and a cavity configured to receive said boss, said boss being rotatably inserted into said cavity such that said boss interlocks with said cavity and so that at least a portion of said top surface of said weight contacts at least a portion of said lower surface of said body end portion.

11. The club head of claim 10, wherein said weight is secured to said body end portion.

12. The club head of claim 11, wherein said weight is fastened to said body using a screw inserted through said weight into said body.

13. The club head of claim 10, wherein said weight further includes a protrusion having a concave surface and wherein said body has a corresponding convex surface.

14. The club head of claim 10, wherein said body end portion corresponds to the heel of said body.

15. The club head of claim 10, wherein said body end portion corresponds to a toe end of said body.

16. The club head of claim 10, wherein said body and said weight each include a front surface, and wherein said front surface of said weight is substantially flush with said front surface of said body in order to form a striking face on said club head.

17. The club head of claim 10, wherein said body includes a sole, said weight includes a bottom surface, and wherein said bottom surface of said weight is substantially flush with said sole.

18. The club head of claim 10, wherein said body comprises a material having a density greater than that of said weight.

19. The club head of claim 18, wherein said body comprises titanium and said weight comprises tungsten.
