Abstract

A golf club head has a striking face. A ledge extends from the perimeter contact rim of the golf club head. The striking face is secured to the club head body proximate the rim. There is a gap between the striking face and the ledge. The inner wall's perimeter edge is disposed in the gap and is in contact with the ledge. The rear surface of the striking face is in contact with a portion of the inner wall.

First claim

The invention claimed is:

1. A golf club head comprising:
a striking face;
a club head body comprising a perimeter contact rim and a ledge extending from the perimeter contact rim, wherein the striking face is secured to the club head body proximate the perimeter contact rim, and wherein the ledge is spaced from a rear surface of the striking face so as to define a gap therebetween; and
an inner wall comprising a perimeter edge,
wherein when the striking face is in a neutral position, at least a first portion of the perimeter edge is disposed in the gap and in contact with the ledge and spaced apart from the rear surface of the striking face and the rear surface of the striking face is in contact with a non-perimeter edge portion of the inner wall, and
wherein when the striking face is in a deflected position, at least the first portion of the perimeter edge is disposed in the gap and spaced apart from both the ledge and the rear surface of the striking face and the rear surface of the striking face is in contact with the non-perimeter edge portion of the inner wall.

2. The golf club head of claim 1 , wherein the ledge extends inward from the perimeter contact rim, and wherein the ledge is offset from the perimeter contact rim, and wherein the inner wall is substantially parallel to the striking face.

3. The golf club head of claim 1 , wherein the perimeter edge is tapered.

4. The golf club head of claim 1 , wherein the club head body further comprises a sole, a topline, a heel, and a toe, and wherein the ledge is disposed proximate at least one of the sole, the topline, the heel, and the toe.

5. The golf club head of claim 4 , wherein the perimeter edge is in contact with a portion of the ledge disposed proximate the topline and the sole.

6. The golf club head of claim 4 , wherein a heel portion of the perimeter edge is unsupported by the ledge when the striking face is in a neutral position.

7. The golf club head of claim 6 , wherein the heel portion of the perimeter edge is in contact with a lip when the striking face is in a deflected position.

8. The golf club head of claim 1 , wherein the perimeter edge of the inner wall has a shape substantially similar to a perimeter edge of the striking face.

9. A golf club head comprising:
a body portion comprising a perimeter contact rim and a ledge extending inward from at least a portion of the perimeter contact rim, wherein the ledge is discrete from the perimeter contact rim;
an inner plate having an edge and a central portion, wherein at least a portion of the edge is in contact with the ledge; and
a striking face secured to the perimeter contact rim, wherein a rear surface of the striking face is in contact with the central portion of the inner plate and spaced apart from the edge of the inner plate when the striking face is in a neutral position, and wherein the edge of the inner plate is tapered and wherein when in the deflected position, the rear surface of the striking face and the perimeter edge of the inner plate define a space therebetween.

10. The golf club head of claim 9 , wherein the rear surface of the striking face is in contact with the central portion of the inner plate when the striking surface is in a deflected position.

11. The golf club head of claim 9 , wherein the inner plate comprises a topline edge, a sole edge, and a heel edge, and wherein when the striking surface is in a neutral position, the topline edge and the sole edge are in contact with the ledge.

12. The golf club head of claim 11 , wherein when the striking surface is in a deflected position, (a) the topline edge and the sole edge are in contact with the ledge, and (b) the heel edge is in contact with a lip extending from the club head body.

13. The golf club head of claim 9 , wherein the striking face is secured about the perimeter contact rim.

14. The golf club head of claim 9 , wherein the body portion comprises a topline edge, a sole edge, a heel edge, and a toe edge, and wherein the ledge extends along substantially the entire length of at least one of the topline edge, the sole edge, the heel edge, and the toe edge.

15. The golf club head of claim 14 , wherein the ledge comprises two ledges, wherein the two ledges are disposed proximate opposing edges of the perimeter contact rim.

16. A golf club head comprising:
a club head body comprising a perimeter contact rim and a ledge extending inward from at least two opposing edges of the perimeter contact rim;
a striking face connected to the club head body proximate the perimeter contact rim; and
an inner wall comprising a central portion defining a central area and an edge surrounding the central portion and defining an edge area less than the central area, wherein a portion of the edge is in contact with the ledge, and wherein a rear surface of the striking face contacts the central portion and is spaced apart from the edge when the striking face is in both a neutral position and a deflected position.

17. The golf club head of claim 16 , wherein a distance between the edge and the rear surface of the striking face in the neutral position is greater than a distance between the edge and the rear surface of the striking face in the deflected position.

18. The golf club head of claim 16 , wherein the central area comprises an area approximately 78% of a total area of the inner wall.

19. The golf club head of claim 16 , wherein the striking face and the inner wall comprise substantially similar perimeter shapes.
