Abstract

A golf club comprising an adjustable fitting member semi-permanently attached rearwardly on a sole is disclosed herein. The fitting member can be rotated to adjust the measured and perceived face angle of the golf club head at address without changing the relative relationship of the club with respect to the shaft, which would alter the lie and loft of the golf club head.

Claims

1. A wood-type golf club head comprising:

a body having a front portion, a crown portion and a sole portion, the body also having a heel end;

a toe end and an aft end; and

an adjustable fitting member disposed on the sole;

wherein the adjustable fitting member can be removed, reoriented, and reattached to the sole to effect a change in the face angle of the wood-type golf club head without affecting loft or lie angles of the wood-type golf club head, and

wherein the adjustable fitting member has a triangular shape with a first apex point, a second apex point and a third apex point wherein the first apex point has a height greater than the second and third apex points, and wherein the second apex point has a height greater than that of the third apex point.

2. The wood-type golf club head according to claim 1, wherein the adjustable fitting member is disposed on the sole proximate the aft end and the heel end.

3. The wood-type golf club head according to claim 1, wherein the golf club head contacts the ground surface at first and second contact points at address, wherein the first contact point is a portion of the sole proximate the front portion, and wherein the second contact point is a portion of the adjustable fitting member.

4. The wood-type golf club head according to claim 1, further comprising a recessed portion in the sole, wherein the adjustable fitting member is disposed within the recessed portion.

5. The wood-type golf club head according to claim 1, wherein the golf club head has a neutral face angle when the second apex point contacts the ground surface.

6. The wood-type golf club head according to claim 1, wherein the golf club head has an open face angle when the third apex point contacts the ground surface.

7. The wood-type golf club head according to claim 1, wherein the golf club head has a closed face angle when the first apex point contacts the ground surface.

8. The wood-type golf club head according to claim 1, wherein the adjustable fitting member has an aperture for placement of a bolt therethrough.

9. The wood-type golf club head according to claim 8, wherein the sole comprises an aperture to receive the bolt after the bolt is inserted through the aperture in the adjustable fitting member.

10. A wood-type golf club comprising:

a golf club head comprising;

a body having a front portion, a crown portion and a sole portion, the body also having a heel end, a toe end and an aft end, the sole portion having a recessed portion proximate the aft end, and

an adjustable fitting member disposed within the recessed portion, the adjustable fitting member having a triangular shape with a first apex point, a second apex point, and a third apex point; and

a shaft connected to the golf club head;

wherein the adjustable fitting member can affect the face angle of the wood-type golf club head without affecting the loft or lie angles of the wood-type golf club head,

wherein the golf club head contacts a ground surface at only two points of contact,

wherein the first point of contact is a portion of the sole proximate the front portion, and

wherein the second point of contact is one of the first, second, and third apex points.

11. The wood-type golf club head of claim 10, wherein the first apex point has a height greater than the second and third apex points, and wherein the second apex point has a height greater than that of the third apex point.

12. The wood-type golf club head according to claim 10, wherein the adjustable fitting member has an aperture for placement of a bolt therethrough.

13. The wood-type golf club head according to claim 12, wherein the recessed portion comprises an aperture to receive the bolt after the bolt is inserted through the aperture in the adjustable tilting member.

14. The wood-type golf club head according to claim 10, wherein the golf club head has a neutral face angle when the second apex point contacts the ground surface.

15. The wood-type golf club head according to claim 10, wherein the golf club head has an open face angle when the third apex point contacts the ground surface.

16. The wood-type golf club head according to claim 10, wherein the golf club head has a closed face angle when the first apex point contacts the ground surface.

17. A method of adjusting the face angle of a wood-type golf club head comprising:

providing a golf club head comprising a front portion, a crown portion, a sole portion, and an aft end, the sole portion having a recessed portion proximate the aft end;

providing an adjustable fitting member that fits within the recessed portion, the adjustable fitting member having a triangular shape with a first apex point, a second apex point, and a third apex point, the first apex point having a height greater than the second and third apex points, and the second apex point having a height greater than that of the third apex point;

rotating the adjustable fitting member so that the apex point having a desired height contacts the ground when the golf club head is placed at address; and

removably securing the adjustable fitting member within the recessed portion.

18. The method of claim 17, wherein the golf club head contacts a ground, surface at only two points.

19. The method of claim 17, wherein the golf club head has a neutral face angle when the second apex point contacts the ground surface, the golf club head has an open face angle when the third apex point contacts the ground surface, and the golf club head has a closed face angle when the first apex point contacts the ground surface.
