Abstract

Disclosed herein are embodiments of adjustable golf clubs comprising features which allow for the adjustment of a lie angle, a loft angle, or both a lie angle and a loft angle of the golf club. In some embodiments, a golf club head includes a body and a hosel, the hosel including an adjustment screw which can be tightened or loosened to adjust the lie and/or loft angles of a golf club head. In some embodiments, certain angles of a golf club head's geometry can be continuously adjustable through a predetermined range of angles.

First claim

We claim:

1. An adjustable golf club head comprising:
a main body;
a screw having threads; and
a hosel having a shaft bore for receiving a golf club shaft, an adjustment bore for receiving the screw, a notch, an unthreaded opening connecting the notch to the adjustment bore, and a threaded opening connecting the notch to the shaft bore, wherein;
the threaded opening has threads complementing the threads of the screw; and
wherein the notch extends inward from a periphery of the hosel beyond a longitudinal axis of the shaft bore.

2. The golf club head of claim 1 wherein the screw extends from the adjustment bore, through the unthreaded opening, through the notch, through the threaded opening, and into the shaft bore.

3. The golf club head of claim 1 wherein adjustment of the screw causes the hosel to rotate with respect to the main body, thereby changing a lie angle of the club head.

4. The golf club head of claim 1 wherein adjustment of the screw causes the hosel to rotate with respect to the main body, thereby changing a loft angle of the club head.

5. The golf club head of claim 1 further comprising a solid piece of material situated within the shaft bore operates to separate a portion of the shaft bore which can receive the screw from a portion of the shaft bore which can receive a golf club shaft.

6. The golf club head of claim 1 further comprising a threaded boss element coupled to the hosel at a distal end portion of the shaft bore.

7. The golf club head of claim 1 further comprising a range limiter coupled to the hosel to mechanically limit tightening of the screw.

8. The golf club head of claim 1 wherein the notch extends past a centerline of the hosel.

9. The golf club head of claim 1 further comprising a threaded boss element coupled to the hosel proximate the threaded opening that provides communication between the shaft bore and the notch.

10. The golf club head of claim 1 wherein the hosel includes a living hinge situated proximate to the notch.

11. A golf club head comprising:
a hosel having a notch formed therein and a shaft bore configured to receive a golf club shaft;
a screw extending into the hosel and through the notch such that adjustment of the screw causes the hosel to bend at the notch; and
wherein the notch extends inward from a periphery of the hosel beyond a longitudinal axis of the shaft bore.

12. The golf club head of claim 11 wherein the hosel includes an adjustment bore and the screw extends from the adjustment bore, through the notch and at least proximate to the shaft bore.

13. The golf club head of claim 12 wherein:
the shaft bore has a first central longitudinal axis;
the adjustment bore has a second central longitudinal axis; and
adjustment of the screw causes the first central longitudinal axis of the shaft bore to rotate with respect to the second central longitudinal axis of the adjustment bore.

14. The golf club head of claim 11 further comprising a bearing pad situated between a head portion of the screw and the notch.

15. The golf club head of claim 11 wherein the hosel includes a living hinge situated proximate to the notch.
