Abstract

An adjustable golf putter utilizes an integrated indexing mechanism for the rotation of the golf club shaft in relation to the putter head. A circular portion of the hosel nests in a cavity formed in the putter head. Matching faces are impressed with a series of radiating serrations incorporated into the head and hosel and no additional parts are required. When pressed together, the serrated faces permit the hosel to rotate in discrete increments selected at time of manufacture. The putter may rotate in increments of 5 degrees for a total of 35 degrees in each direction from a center marking feature. The hosel is locked in a selected position by simply tightening the hosel screw. The putter can be adjusted for use by both right and left handed golfers without disassembly.

Claims

1. An adjustable clubhead assembly comprising:

a hosel including a shaft receiving recess and a hub portion, the shaft receiving recess defining a shaft axis, the hub portion defining a first face and a rotation axis, the hub portion including a first engagement element being disposed on the first face;

a clubhead defining a clubhead axis and including a hub receptor being disposed on a rear section of the clubhead, the hub receptor defining a second face and including a second engagement element being disposed on the second face thereof, the hub receptor being rotatably engageable to the hub portion about the rotation axis with the first face mating with the second face, the first engagement element being matable with the second engagement element for impeding rotational movement of the hosel with respect to the clubhead at a clubhead angle; and

attachment means for securing the hosel to the clubhead.

2. The assembly of claim 1 wherein the first engagement element includes at least one tooth projection.

3. The assembly of claim 2 wherein the second engagement element includes at least one notch.

4. The assembly of claim 1 wherein the first and second engagement elements are a radial serration profile.

5. The assembly of claim 1 wherein the hub portion is cylindrical.

6. The assembly of claim 5 wherein the hub receptor is a cylindrical concave recess portion whereinto the hub portion is received.

7. The assembly of claim 6 wherein the concave recess portion is defined by a raised socket wall, and wherein the raised socket wall substantially surrounds the cylindrical hub portion.

8. The assembly of claim 1 wherein the clubhead angle is defined by the orientation of the shaft axis with respect to the clubhead axis.

9. The assembly of claim 1 wherein the hub portion of the hosel includes a guide selection marking and the hub receptor includes at least one selection marking corresponding to the clubhead angle, the guide selection marking being alignable with the selection marking for orienting the hosel at the clubhead angle with respect to the clubhead.

10. The assembly of claim 1 wherein the attachment means is a screw hole and screw.

11. An adjustable golf club comprising:

an elongate shaft defining a distal end and a shaft axis;

a hosel including a shaft receiving recess and a hub portion, the shaft receiving recess being sized and configured to receive the distal end of the shaft, the hub portion defining a first face and a rotation axis, the hub portion including a first engagement element being disposed on the first face;

a clubhead defining a clubhead axis and including a hub receptor being disposed on a rear section of the clubhead, the hub receptor defining a second face and including a second engagement element being disposed on the second face thereof, the hub receptor being rotatably engageable to the hub portion about the rotation axis with the first face mating with the second face, the first engagement element being matable with the second engagement element for impeding rotational movement of the hosel with respect to the clubhead at a clubhead angle; and

attachment means for securing the hosel to the clubhead.

12. The club of claim 11 wherein the first engagement element includes at least one tooth projection.

13. The club of claim 12 wherein the second engagement element includes at least one notch.

14. The club of claim 11 wherein the first and second engagement elements are a radial serration profile.

15. The club of claim 11 wherein the hub portion is cylindrical.

16. The club of claim 15 wherein the hub receptor is a cylindrical concave recess portion whereinto the hub portion is received.

17. The club of claim 16 wherein the concave recess portion is defined by a raised socket wall, and wherein the raised socket wall substantially surrounds the cylindrical hub portion.

18. The club of claim 11 wherein the clubhead angle is defined by the orientation of the shaft axis with respect to the clubhead axis.

19. The club of claim 11 wherein the hub portion of the hosel includes a guide selection marking and the hub receptor includes at least one selection marking corresponding to the clubhead angle, the guide selection marking being alignable with the selection marking for orienting the hosel at theclubhead angle with respect to the clubhead.

20. The club of claim 11 wherein the attachment means is a screw hole and screw.
