Abstract

A golf club head comprising a channel or a pair of parallel rails and a slidable weight assembly that can be removably fixed at any point within the channel or to the rails is disclosed herein. The slidable weight assembly preferably comprises a weight portion and base that can be turned 45 to 90 degrees to reversibly fix the slidable weight assembly within the channel or to the rails.

First claim

We claim:

1. A golf club head comprising:
a body comprising a first rail and a second rail that are spaced from, and extend parallel to, one another; and
a slidable weight assembly comprising:
a weight portion comprising a through bore; and
a cam comprising a top portion, a keyed bore, a neck, and a base having a long side with a first length and a short side with a second length,

wherein the first rail and second rail form a channel having a floor with a first width and an upper opening with a second width,
wherein the first width is greater than the second width,
wherein the base is disposed within the channel,
wherein the neck extends through the upper opening,
wherein the slidable weight assembly is movable between the first and second rails when the long side of the base is oriented so that it is parallel with the first and second rails, and
wherein turning the cam by 45 to 90 degrees reversibly fixes the slidable weight assembly to the first and second rails.

2. The golf club head of claim 1 , wherein a majority of the weight portion is disposed above the first and second rails.

3. The golf club head of claim 1 , wherein the first length is greater than the second length, wherein the neck is disposed within the through bore, and wherein the keyed bore is sized to receive a tool.

4. The golf club head of claim 1 , wherein the golf club head comprises a recessed area, and wherein the first and second rails are disposed within the recessed area.

5. The golf club head of claim 4 , wherein the recessed area is in communication with a weight port, and wherein the slidable weight assembly is sized to fit within the weight port to access the first and second rails.

6. The golf club head of claim 1 , wherein at least one of the first and second rails comprises an inner wall that forms an angle with the floor, wherein the angle is less than 90°.

7. The golf club head of claim 6 , wherein the angle is between 45° and 85°.

8. The golf club head of claim 7 , wherein the angle is approximately 70°.

9. The golf club head of claim 1 , wherein at least one of the first and second rails has a thickness of less than 0.100 inch.

10. The golf club head of claim 1 , wherein the first and second rails are spaced from one another by a distance of between 0.500 and 1.00 inch.

11. The golf club head of claim 1 , further comprising a pair of small rails extending from a lower surface of the weight portion, wherein the small rails rest against, and space the lower surface from, the first and second rails.

12. A golf club head comprising:
a body comprising a first rail and a second rail that are spaced from, and extend parallel to, one another; and
a slidable weight assembly comprising:
a weight portion comprising a through bore, a lower surface, and a pair of small rails extending from the lower surface; and
a cam comprising a top portion, a keyed bore, a neck, and a base having a long side with a first length and a short side with a second length,

wherein the first rail and second rail form a channel having a floor with a first width and an upper opening with a second width,
wherein the base is disposed within the channel,
wherein the neck extends through the upper opening,
wherein the small rails rest against, and space the lower surface from, the first and second rails, and
wherein the slidable weight assembly is movable between the first and second rails when the long side of the base is oriented so that it is parallel with the first and second rails.

13. The golf club head of claim 12 , wherein the golf club head comprises a recessed area, and wherein the first and second rails are disposed within the recessed area.

14. The golf club head of claim 13 , wherein the recessed area is in communication with a weight port, and wherein the slidable weight assembly is sized to fit within the weight port to access the first and second rails.

15. The golf club head of claim 12 , wherein turning the cam reversibly fixes the slidable weight assembly to the first and second rails.

16. A golf club head comprising:
a body comprising a recessed area, a weight port, and first and second rails; and
a slidable weight assembly comprising:
a weight portion comprising a through bore; and
a cam comprising a top portion, a keyed bore, a neck, and a base having a long side with a first length and a short side with a second length,

wherein the first and second rails are disposed within the recessed area and are spaced from, and extend parallel to, one another,
wherein the first rail and second rail form a channel having a floor with a first width and an upper opening with a second width,
wherein the recessed area is in communication with the weight port,
wherein the first width is greater than the second width,
wherein the base is disposed within the channel,
wherein the neck extends through the upper opening,
wherein a majority of the weight portion is disposed above the first and second rails,
wherein the slidable weight assembly is movable between the first and second rails when the long side of the base is oriented so that it is parallel with the first and second rails, and
wherein turning the cam reversibly fixes the slidable weight assembly to the first and second rails.

17. The golf club head of claim 16 , wherein the golf club head is a driver-type golf club head.

18. The golf club head of claim 17 , wherein the driver-type golf club head further comprises a composite crown, and wherein the body is composed of a titanium alloy.
