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.

Claims

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.
