Abstract

The invention provides a golf club head having adjustable weight, allowing the golfer to fine tune the club for his or her swing. The club head includes a body having a ball-striking face, a sole, a crown, and a side extending rearwardly from the face. The body defines an interior cavity and a recess on a selected wall of the body spaced apart from the striking face. A threaded opening is disposed in the recess. The club head further includes a weight assembly having fastener and a mass element configured to be press-fit into the recess the such that a first end is adjacent the bottom of the recess. The mass element also has an aperture configured to receive the fastener flush. The fastener removably attaches the weighting assembly to the selected wall of the club head. Pressure from the fastener attachment provides a press-fit of the mass element in the tapered recess of the selected wall.

Claims

1-21. -21. (canceled)

22. A golf club head comprising:

a head body having at least one recess formed therein, wherein the recess is at least partially delineated by a first recess wall and a recess bottom;

an opening formed in the recess bottom;

a weight body disposed in the recess;

a first aperture having a first diameter formed in the weight body;

a second aperture having a second diameter formed in the weight body;

a cavity formed in the weight body, wherein the first and second apertures are coupled to the cavity; and

a fastener having a fastener head and a fastener body, the fastener head having a third diameter, wherein the fastener head is disposed in the cavity, the fastener body extends through the second aperture, the first and second diameters are less than the third diameter, and the fastener body and the opening in the recess bottom are adapted to be removably engaged.

23. The golf club head of claim 22, wherein a portion of the recess widens towards an outer surface of the head body, and wherein a portion of the weight body widens towards an outer surface of the head body.

24. The golf club head of claim 22, wherein the first diameter is adapted to provide tool access to the fastener head.

25. The golf club head of claim 22, wherein the opening in the recess bottom and the fastener body are threadably engaged.

26. The golf club head of claim 22, wherein the opening in the recess bottom has a depth at least 1.5 times a diameter of the fastener body.

27. The golf club head of claim 22, further comprising a boss formed in the recess bottom, wherein the opening in the recess bottom is formed in the boss.

28. The golf club head of claim 27, wherein the boss extends towards an outer surface of the body.

29. The golf club head of claim 27, wherein the boss extends away from an outer surface of the body.

30. The golf club head of claim 22, wherein a cross sectional shape of the weight body is triangular, hexagonal, oval, or rectangular.

31. The golf club head of claim 22, wherein the weight body has a uniform density.

32. The golf club head of claim 22, wherein the weight body has a non-uniform density.

33. The golf club head of claim 22, wherein the at least one recess is disposed on a sole, top wall, side wall, heel portion, or toe portion of the head body.

34. The golf club head of claim 22, wherein a portion of the recess and a portion of the weight body are coupled by means of a press fit.

35. The golf club head of claim 22, wherein the cavity is adapted such that the fastener may be rotated with respect to the weight body.

36. The golf club head of claim 22, wherein the weight body is comprised of a first material having a first density, the head body is comprised of a second material having a second density, and the first density is different from the second density.

37. The golf club head of claim 22, further comprising a low friction element disposed between the fastener head and the weight body.

38. A golf club head comprising:

a head body having at least one recess formed therein, wherein the recess is at least partially delineated by a first recess wall and a recess bottom;

an opening formed in the recess bottom;

a mass element disposed in the recess;

a first aperture having a first diameter formed in the mass element;

a second aperture having a second diameter formed in the mass element;

a retaining element coupled to the mass element;

a third aperture having a third diameter formed in the retaining element; and

a fastener having a fastener head and a fastener body, the fastener head having a fourth diameter, wherein the fastener head is disposed in the second aperture, the fastener body extends through the first aperture, the fourth diameter is greater than the first and third diameters, and the fastener body and the opening in the recess bottom are adapted to be removably engaged.

39. The golf club head of claim 38, wherein the mass element and the retaining element are threadably engaged.

40. The golf club head of claim 39, wherein an outer diameter of the retaining element is threadably engaged with an inner diameter of the mass element.

41. The golf club head of claim 38, further comprising a fourth aperture having a fifth diameter formed in the retaining element, wherein the fifth diameter is greater than the fourth diameter.

42. The golf club head of claim 38, wherein a portion of the recess widens towards an outer surface of the head body, and wherein a portion of the mass element widens towards an outer surface of the body.

43. The golf club head of claim 38, wherein the third diameter is adapted to provide tool access to the fastener head.

44. The golf club head of claim 38, wherein the opening in the recess bottom and the fastener body are threadably engaged.

45. The golf club head of claim 38, wherein the opening in the recess bottom has a depth at least 1.5 times a diameter of the fastener body.

46. The golf club head of claim 38, further comprising a boss formed in the recess bottom, wherein the opening in the recess bottom is formed in the boss.

47. The golf club head of claim 46, wherein the boss extends towards an outer surface of the body.

48. The golf club head of claim 46, wherein the boss extends away from an outer surface of the body.

49. The golf club head of claim 38, wherein a cross sectional shape of the mass element is triangular, hexagonal, oval, or rectangular.
