Abstract

A golf club head comprising a variable thickness profile comprising a thick central portion; a transition portion; and a thin perimeter portion; wherein said transition portion surrounds said thick central portion; wherein said thin perimeter portion surrounds said transition portion; wherein said thick central portion comprises a center, said center of said thick central portion located equidistant from a heel most portion of said thick central portion and a toe most portion of said thick central portion; wherein said center of said thick central portion is offset from said geometric center of said striking face. The present invention also discloses a flexure feature located near a frontal sole portion of the golf club head, wherein the flexure has a specific thickness profile adapted to respond to the needs of the present golf club head.

First claim

We claim:

1. A golf club head comprising:
a striking face;
a posterior body comprising a crown portion and a sole portion, wherein said crown portion is coupled to an upper end of said striking face and said sole portion is coupled to a lower portion of said striking face;
wherein said sole portion further comprises a flexure spaced from said striking face, said flexure further comprising;
a central portion, located near a geometric center of said striking face;
a plurality of two or more intermediate transition regions, located nears a toe portion and a heel portion of said central portion; and
a plurality of two or more outer transition regions, located near a toe portion and a heel portion of said plurality of two or more intermediate transition regions;

wherein said central portion further comprises, a front wall, a rear wall, and an apex, and
wherein said front wall has a wall thickness greater than a wall thickness of said rear wall, said rear wall has a wall thickness greater than a wall thickness of said plurality of two or more intermediate transition regions, and said plurality of two or more intermediate transition regions has a wall thickness greater than a wall thickness of said plurality of two or more outer transition regions.

2. The golf club head of claim 1 , wherein said wall thickness of said front wall is between about 1.50 to about 2.0 mm.

3. The golf club head of claim 2 , wherein said wall thickness of said front wall is between about 1.60 mm to about 1.90 mm.

4. The golf club head of claim 3 , wherein said wall thickness of said front wall is between about 1.65 mm to about 1.85 mm.

5. The golf club head of claim 2 , wherein said wall thickness of said rear wall is between about 1.20 mm to about 1.70 mm.

6. The golf club head of claim 5 , wherein said wall thickness of said plurality of intermediate transition regions is between about 1.10 mm to about 1.60 mm.

7. The golf club head of claim 6 , wherein said wall thickness of said plurality of outer transition regions is between about 0.80 mm to about 1.10 mm.
