Abstract

A golf club head includes a club body and a resting face angle adjuster. The club body includes a crown opposite a sole, a toe end opposite a heel end, a back end opposite a face, and a hosel. The sole includes a sole surface. The resting face angle adjuster includes an adjustment member having a keel surface, and a recess formed in the sole such that a portion of the sole surface at least partially bounds the recess. The adjustment member is disposed in the recess and positionable between a first adjustment position and a second adjustment position. In the first adjustment position, the keel surface is at a first distance relative to the portion of the sole surface. In the second adjustment position, the keel surface is at a second distance relative to the portion of the sole surface not equal to the first distance in the direction.

First claim

What is claimed is:

1. A golf club head comprising:
a club body having a crown opposite a sole, a toe end opposite a heel end, a back end opposite a face, and a hosel, the sole including a sole surface; and
a resting face angle adjuster including an adjustment member positionable within a recess formed in the sole and defining a recess edge, the adjustment member including a keel surface rotatable about a pivot axis between a first adjustment position and a second adjustment position,
the adjuster configured such that when the adjustment member is positioned in the first adjustment position, a portion of the keel surface is at a first distance from a portion of the recess edge and when the adjustment member is positioned in the second adjustment position, the portion of the keel surface is at a second distance from the portion of the recess edge greater than the first distance
wherein:
the adjustment member includes a first end and a second end, and the keel surface extends between the first and second ends, the adjuster configured such that when the adjustment member is positioned in the first adjustment position, a portion of the keel surface adjacent the first end protrudes outside of the recess, and a portion of the keel surface adjacent the second end is situated within the recess; and when the adjustment member is positioned in the second adjustment position, the portion of the keel surface adjacent the first end is situated within the recess, and the portion of the keel surface adjacent the second end protrudes outside of the recess.

2. The golf club head of claim 1 , wherein:
the adjustment member is further rotatable to a third adjustment position, the adjuster configured such that when the adjustment member is positioned in the third adjustment position, the keel surface is generally coplanar with a portion of the sole surface.

3. The golf club head of claim 1 , wherein:
the adjustment member includes a bottom surface opposite the keel surface; and
the adjuster includes a threaded bore adjacent the recess, and an adjustment screw selectively receivable into the threaded bore, the adjustment screw having a tip portion selectively engageable with the bottom surface,
wherein the adjustment screw is rotatable to reposition the adjustment member between the first and second adjustment positions.

4. The golf club head of claim 1 , wherein the recess extends longitudinally from a recess front wall, closer to the face than the rear end, to a recess back wall, closer to the rear end than the face.

5. The golf club head of claim 1 , wherein the recess is positioned on the sole closer to the heel end than to the toe end.

6. The golf club head of claim 1 , wherein a resting face angle of the golf club head is altered by between 1 and 20 degrees when the adjustment member is reoriented from the first adjustment position to the second adjustment position.

7. The golf club head of claim 1 , wherein:
by orienting the adjustment member in the first adjustment position, the resting face angle of the golf club head is a more open position than that of a similar club head lacking the adjustment member in the first adjustment position; and
by orienting the adjustment member in the second adjustment position, the resting face angle of the golf club head is a more closed position than that of a similar club head lacking the adjustment member in the first adjustment position.

8. The golf club head of claim 1 , wherein:
either the first end or the second end of the adjustment member defines a keel point on which the golf club rests against the ground when in a resting or address position;
the golf club head comprises a center of gravity;
the keel point is forward of the center of gravity when the adjustment member is in the first adjustment configuration; and
the keel point is behind the center of gravity when the adjustment member is in the second adjustment configuration.

9. The golf club head of claim 1 , wherein the adjustment member can only be positioned in a discrete number of adjustment positions.

10. The golf club head of claim 1 , wherein the adjustment member can be repositioned in at any intermediate position between the second adjustment position and the third adjustment position.

11. A golf club head comprising:
a club body having a crown opposite a sole, a toe end opposite a heel end, a back end opposite a face, and a hosel, the sole including a sole surface; and
a resting face angle adjuster including an adjustment member positionable within a recess formed in the sole and defining a recess edge, the adjustment member including a keel surface rotatable about a pivot axis between a first adjustment position, a second adjustment position, and a neutral position;
wherein:
the adjustment member includes a first end and a second end, and the keel surface extends between the first and second ends, the adjuster configured such that:
when the adjustment member is positioned in the first adjustment position, a portion of the keel surface adjacent the first end protrudes outside of the recess, and a portion of the keel surface adjacent the second end is situated within the recess;
when the adjustment member is positioned in the second adjustment position, the portion of the keel surface adjacent the first end is situated within the recess, and the portion of the keel surface adjacent the second end protrudes outside of the recess; and
when the adjustment member is positioned in the neutral position, the keel surface is generally coplanar with a portion of the sole surface.

12. The golf club head of claim 11 , wherein:
the adjustment member includes a bottom surface opposite the keel surface; and
the adjuster includes a threaded bore adjacent the recess, and an adjustment screw selectively receivable into the threaded bore, the adjustment screw having a tip portion selectively engageable with the bottom surface,
wherein the adjustment screw is rotatable to reposition the adjustment member between the first and second adjustment positions.

13. The golf club head of claim 11 , wherein the recess extends longitudinally from a recess front wall, closer to the face than the rear end, to a recess back wall, closer to the rear end than the face.

14. The golf club head of claim 11 , wherein the recess is positioned on the sole closer to the heel end than to the toe end.

15. The golf club head of claim 11 , wherein a resting face angle of the golf club head is altered by between 1 and 20 degrees when the adjustment member is reoriented from the first adjustment position to the second adjustment position.

16. The golf club head of claim 11 , wherein:
by orienting the adjustment member in the first adjustment position, a resting face angle of the golf club head is a more open position than that of a similar club head lacking the adjustment member in the first adjustment position; and
by orienting the adjustment member in the second adjustment position, the resting face angle of the golf club head is a more closed position than that of a similar club head lacking the adjustment member in the first adjustment position.

17. The golf club head of claim 11 , wherein:
either the first end or the second end of the adjustment member defines a keel point on which the golf club rests against the ground when in a resting or address position;
the golf club head comprises a center of gravity;
the keel point is forward of the center of gravity when the adjustment member is in the first adjustment configuration; and
the keel point is behind the center of gravity when the ad
