Abstract

The present invention is directed to a golf club having a playing characteristic that is communicated to a player based upon a vibration damping material that is colorized and visible from outside of the club head, thereby communicating to a golfer information about the playing characteristics of the club.

Claims

1. A golf club head, comprising:

a body portion comprising a sole, topline, heel, and toe;

a hitting face insert attached to a front of the body portion;

a channel formed along a portion of the body portion, at least a first portion of the channel having an opening directed only toward a back surface of the face insert; and

a damping material disposed in at least the first portion of the channel and in contact with the back surface of the face insert, wherein an exposed portion of the damping material includes a colorant and is colorized by the inclusion of the colorant and is visible from an outside of the club head, wherein the colorant provides visual information indicative of one or more playing characteristics of the club head, the visual information selected from the group consisting of a damping property of the damping material, density of the damping material, weight placement along the club head, weight distribution along the club head, and loft setting of the club head.

2. The golf club of claim 1, wherein a first portion of the damping material near the sole comprises a material having a first density and a second portion of the damping material near the topline comprises a material having a second density lower than the first density.

3. The golf club of claim 2, wherein the first portion has a first color and the second portion has a second color different than the first color and both first and second portions are visible from outside of the club head through one or more openings defined along the body portion.

4. The golf club of claim 2, further comprising:

a third portion of the damping material disposed in at least a portion of the channel, wherein the third material is different from the first and second portions.

5. The golf club head of claim 4, wherein the third material is disposed in only a lower portion of the entire channel near the sole of the body portion.

6. The golf club head of claim 5, wherein the third material has a greater density than the first and second materials.

7. The golf club head of claim 5, wherein the third portion comprises tungsten.

8. The golf club head of claim 5, wherein the second and third portions of material comprise UV stabilizers.

9. The golf club of claim 1, wherein the exposed portion is visible through an opening defined along a back of the club head.

10. The golf club of claim 9, wherein the opening is near the topline.

11. The golf club of claim 9, wherein the opening is near the sole.

12. The golf club of claim 1, wherein the exposed portion is visible through an elongated opening defined on the body portion.

13. The golf club of claim 1, wherein the exposed portion is visible through a circular opening defined on the body portion.

14. The golf club of claim 1, wherein the exposed portion comprises a transparent material covering a colored underlying material.

15. The golf club of claim 1, wherein the colorized portion of material includes a fluorescent pigment.

16. The golf club of claim 1, wherein the damping material further comprises a second exposed colorized portion of a different color than the first portion and visible from an outside of the club head.

17. The golf club head of claim 16, wherein the second portion is disposed in only a lower portion of the entire channel near the sole of the body portion.

18. The golf club head of claim 1, wherein the second portion of material is disposed in only an upper portion of the entire channel near the topline of the body portion.

19. The golf club of claim 1, further wherein no material is disposed within an open region of the channel creating a hollow space, wherein the hollow space is exposed by an opening.
