Abstract

A golf club head comprising a slidable weight for adjusting the location of the golf club head center of gravity, as well as the golf club head bias, is disclosed herein. In particular, the golf club head, which may be a wood or iron-type head, comprises a pair of rails extending along at least one surface, such as a rear surface of an iron type head or a channel disposed in a wood-type head, and a slidable weight comprising a pair of grooves sized to receive the rails. In some embodiments, an applique or one or more clips are applied over or to the rails to prevent the weight from disengaging from the golf club head.

First claim

We claim:

1. A golf club head comprising:
a face component;
a body comprising a channel;
an applique sized to cover the channel; and
a weight comprising a pair of grooves,
wherein the channel comprises a pair of protruding rails extending parallel to one another,
wherein the grooves are sized to receive at least a portion of the rails
wherein the channel comprises a pocket region, and
wherein the applique fills the pocket region.

2. The golf club head of claim 1 , wherein the weight comprises a mass of 2 to 10 grams.

3. The golf club head of claim 1 , further comprising a screw, wherein the screw reversibly fixes the weight to the rails.

4. The golf club head of claim 1 , wherein the applique comprises a cutout, and wherein the weight is visible through the cutout when the applique is affixed to the golf club head.

5. The golf club head of claim 4 , wherein the cutout is filled with a translucent material.

6. The golf club head of claim 5 , wherein the applique is composed of a lightweight material selected from the group consisting of plastic, rubber, composite, and aluminum alloy.

7. The golf club head of claim 1 , wherein the applique comprises a cutout, and wherein the cutout does not extend over the pocket region when the applique is affixed to the golf club.

8. The golf club head of claim 1 , further comprising an adjustable hosel.

9. The golf club head of claim 1 , wherein the golf club head is selected from the group consisting of a driver-type head, a fairway wood-type head, and a hybrid-type head.

10. The golf club head of claim 9 , wherein the golf club head is a driver-type head, wherein the body comprises a composite crown, a metal sole, an adjustable hosel, a heel side, and a toe side, and wherein the channel is disposed in the sole and extends from the heel side to the toe side.

11. The golf club head of claim 1 , wherein channel has a first length, wherein each of the pair of rails has a second length, and wherein the first length is greater than the second length.

12. A golf club head comprising:
a face component;
a body comprising a pair of parallel rails;
at least one clip sized to receive the pair of rails;
at least one screw; and
a weight comprising a pair of grooves,
wherein the grooves are sized to receive at least a portion of the rails,
wherein the screw reversibly fixes the weight to the rails, and
wherein the at least one clip prevents the weight from disengaging from the rails.

13. The golf club head of claim 12 , wherein the at least one clip comprises first and second clips.

14. The golf club head of claim 12 , wherein the body comprises a hosel having an adjustable structure.

15. The golf club head of claim 12 , wherein the body comprises a top surface, a bottom surface, and a rear surface, and wherein the pair of parallel rails is disposed on the rear surface.

16. The golf club head of claim 15 , further comprising an applique, wherein the applique comprises a cutout portion, and wherein the weight is visible through the cutout portion when the applique is engaged with the body.

17. The golf club head of claim 16 , wherein the applique is composed of a material selected from the group consisting of plastic, rubber, and composite.

18. The golf club head of claim 16 , wherein the cutout portion is filled with a material selected from the group consisting of plastic and glass.

19. The golf club head of claim 12 , wherein the weight has a mass of 2 to 10 grams.
