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 crown, a sole, a heel side, a toe side, and an edge portion where the crown makes contact with the sole;
an applique sized to cover the channel; and
a weight comprising a pair of grooves,
wherein the sole comprises a channel,
wherein the channel comprises a pair of protruding rails extending parallel to one another, and
wherein the grooves are sized to receive the rails.

2. The golf club head of claim 1 , wherein the channel extends along at least a part of the edge portion.

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

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

5. 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.

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

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

8. The golf club head of claim 1 , wherein the channel comprises a pocket region, and wherein the applique fills the pocket region.

9. The golf club head of claim 8 , wherein the applique comprises a cutout, and wherein the cutout does not extend over the pocket region.

10. The golf club head of claim 1 , wherein the face component and the sole are composed of a metal material, and wherein the crown is composed of a non-metal material.

11. The golf club head of claim 10 , wherein the crown is composed of a composite material.

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

13. 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.

14. An iron-type golf club head comprising:
a body comprising a face, a top surface, a bottom surface, a hosel, a rear surface, a toe side, and a heel side;
a pair of parallel rails;
an applique; and
a weight comprising a pair of grooves sized to receive the rails,
wherein the applique reversibly fixes the weight to the rails, and
wherein the pair of parallel rails is disposed on the rear surface.

15. The iron-type golf club head of claim 14 , wherein the pair of parallel rails extends from the heel side to the toe side.

16. The iron-type golf club head of claim 14 , further comprising a screw, wherein the screw reversibly fixes the weight to the rails.

17. An iron-type golf club head comprising:
a body comprising a face, a top surface, a bottom surface, a hosel, a rear surface, a toe side, and a heel side;
a pair of parallel rails; and
a weight comprising a pair of grooves sized to receive the rails,
wherein the pair of parallel rails is disposed on the rear surface, and
wherein the hosel comprises an adjustable structure.

18. An iron-type golf club head comprising:
a body comprising a face, a top surface, a bottom surface, a hosel, a rear surface, a toe side, and a heel side;
a pair of parallel rails;
at least one clip sized to receive the pair of rails; and
a weight comprising a pair of grooves sized to receive the rails,
wherein the pair of parallel rails is disposed on the rear surface, and
wherein the at least one clip prevents the weight from disengaging from the rails.
