Abstract

In one embodiment, a golf club head which has a club head body, a means to attach the club head body to a shaft, a striking face wall to address a ball during a golf club stroke and a bottom surface adapted to pass adjacent the ground during the golf club stroke, includes a vibration damping member of shock-absorptive material disposed within the club head body and extending in a plane outside the plane containing the striking face wall. The vibration damping member is preferably disposed either substantially perpendicular to the striking face wall or substantially parallel to the bottom surface. The damping member preferably abuts the striking face wall without penetrating therethrough.

Claims

1. A golf club head body having an outer periphery which includes a substantially planar front striking-face surface to address a ball during a golf club stroke and a bottom surface adapted to pass adjacent the ground during the golf club stroke, said club head body comprising at least one substantially planar shock-absorptive vibration damping portion wherein at least part of said vibration damping portion extends latitudinally along a part of said outer periphery;

and

wherein said damping portion is substantially parallel to said bottom portion.

2. The club head body according to claim 1 wherein said damping portion extends across substantially an entire cross-section of said golf club head body.

3. The club head body according to claim 1 further comprising a plurality of shock-absorptive vibration damping portions.

4. The club head body according to claim 1 wherein said golf club head is the head of a putter.

5. The club head body according to claim 1 wherein said golf club head is the head of an iron.

6. The club head body according to claim 1 wherein said golf club head is the head of a wood.

7. A golf club head body having an outer periphery which includes a substantially planar front striking-face surface to address a ball during a golf club stroke and a bottom surface adapted to pass adjacent the ground during the golf club stroke, said club head body comprising at least one substantially planar shock-absorptive vibration damping portion;

wherein said damping portion extends rearwardly from said planar striking-face surface; and

wherein said damping portion is substantially perpendicular to said striking-face surface.

8. A golf club head comprising:

a club head body having an outer periphery which includes a substantially planar striking face portion to address a ball during a golf club stroke and a bottom portion adapted to pass adjacent the ground during the golf club stroke, said club head body being provided with at least one slot disposed outside the plane of said striking face portion; and

a shock-absorptive vibration damping member disposed in said at least one slot;

wherein at least part of said vibration damping member extends latitudinally along a part of said outer periphery;

wherein said slot is substantially parallel to said bottom portion.

9. The golf club head according to claim 8 wherein said vibration damping member substantially fills said slot.

10. The golf club head according to claim 8 wherein said slot lies substantially in a plane.

11. The golf club head according to claim 8 wherein said slot extends rearwardly from said planar striking face portion.

12. The golf club head according to claim 8 wherein at least part of said vibration damping member forms part of said outer periphery.

13. The golf club head according to claim 8 further comprising a plurality of slots and a plurality of shock-absorptive vibration damping members disposed in respective said slots.

14. The golf club head according to claim 8 wherein said golf club head is the head of a wood.

15. A golf club head comprising:

a club head body having an outer periphery which includes a substantially planar striking face portion to address a ball during a golf club stroke and a bottom portion adapted to pass adjacent the ground during the golf club stroke, said club head body being provided with at least one slot disposed outside the plane of said striking face portion; and

a shock-absorptive vibration damping member disposed in said at least one slot;

wherein said slot extends rearwardly from said planar striking face portion; and

wherein said slot is substantially perpendicular to said striking face portion.

16. The golf club head according to claim 15 wherein said golf club head is the head of a putter.

17. The golf club head according to claim 15 wherein said golf club head is the head of an iron.

18. A golf club head comprising:

a club head body having an outer peripheral which includes a substantially planar striking face portion to address a ball during a golf club stroke and a bottom portion adapted to pass adjacent the ground during the golf club stroke, said club head body being provided with a slot disposed outside the plane of said striking face portion; and

a shock-absorptive vibration damping material injected into said slot; and

said vibration damping material extending along said part of said outer periphery;

wherein said slot is substantially parallel to said bottom portion.

19. The club head of claim 18 wherein said damping material is of the group consisting of thermosetting resin and plastic.

20. The club head of claim 19 wherein said damping material is a thermosetting resin and said club head further including a sealing filler material sealing said slot.

21. The club head of claim 19 including a sealing filler material sealing said slot.

22. A substantially solid golf club head body having an outer periphery which includes a substantially planar front striking-face surface to address a ball during a golf club stroke and a bottom surface adapted to pass adjacent the ground during the golf club stroke, said club head body comprising at least one substantially planar shock-absorptive vibration damping portion;

and

wherein said damping portion is substantially parallel to said bottom portion.

23. A substantially solid golf club head body having an outer periphery which includes a substantially planar front striking-face surface to address a ball during a golf club stroke and a bottom surface adapted to pass adjacent the ground during the golf club stroke, said club head body comprising at least one substantially planar shock-absorptive vibration damping portion;

wherein said damping portion extends rearwardly from said planar striking-face surface; and

wherein said damping portion is substantially perpendicular to said striking-face surface.

24. A golf club head comprising:

a substantially solid club head body having an outer periphery which includes a substantially planar striking face portion to address a ball during a golf club stroke and a bottom portion adapted to pass adjacent the ground during the golf club stroke, said club head body being provided with at least one slot disposed outside the plane of said striking face portion; and

a shock-absorptive vibration damping member disposed in said at least one slot;

wherein said slot is substantially parallel to said bottom portion.

25. A golf club head comprising:

a substantially solid club head body having an outer periphery which includes a substantially planar striking face portion to address a ball during a golf club stroke and a bottom portion adapted to pass adjacent the ground during the golf club stroke, said club head body being provided with at least one slot disposed outside the plane of said striking face portion; and

a shock-absorptive vibration damping member disposed in said at least one slot;

wherein said slot extends rearwardly from said planar striking face portion; and

wherein said slot is substantially perpendicular to said striking face portion.
