First Claim
Patent Images
1. A golf club head comprising:
- a body having a top wall, a bottom wall and a front wall arranged for impacting a golf ball, said front wall having an inner surface and an outer surface; and
said front wall varying in thickness and having a bulging area of increased thickness on said inner surface, said bulging area of increased thickness including a generally ring shaped mass projecting rearwardly from said inner surface of said front wall, said front wall having a maximum thickness dimension measured through said ring shaped mass, said front wall tapering in thickness from said maximum thickness dimension to a thickness dimension located inside said ring shaped mass that is less than said maximum thickness dimension, said front wall also tapering in thickness from said maximum thickness dimension to a thickness dimension located outside said ring shaped mass that is less than said maximum thickness dimension.

Abstract
A golf club head includes a body with a top wall, a bottom wall, and a front wall arranged for impacting a golf ball. The front wall has an inner surface and an outer surface. The front wall varies in thickness and has a bulging area of increased thickness on its inner surface. The bulging area of increased thickness includes a generally ring shaped mass that projects rearwardly from the front wall. A generally cone shaped mass, that also projects rearwardly from the front wall, may be located inside the ring shaped mass.

6. A golf club head comprising:
-
a body having a top wall, a bottom wall and a front wall arranged for impacting a golf ball, said front wall having a geometric center, an inner surface, an outer surface and a perimeter adjacent said top and bottom walls; and
said front wall including a generally ring shaped stiffening region projecting rearwardly from said inner surface, said ring shaped stiffening region having a thickness that tapers from a maximum dimension disposed around the geometric center of said front wall to a dimension located proximal the perimeter of said front wall that is less than said maximum dimension in order to provide said inner surface with a smooth contour. - View Dependent Claims (7)
the thickness of said ring shaped stiffening region tapers from said maximum dimension which is disposed around the geometric center of said front wall to a dimension located proximal the geometric center of said front wall that is less than said maximum dimension.

8. A golf club head comprising:
-
a body having a top wall, a bottom wall and a front wall arranged for impacting a golf ball, said front wall having a geometric center, an inner surface, an outer surface and a perimeter adjacent said top and bottom walls; and
said front wall including a locally thickened region on said inner surface surrounding said geometric center, said locally thickened region tapering from a maximum thickness dimension disposed around said geometric center to a lesser thickness dimension located proximal said geometric center, said locally thickened region also tapering from said maximum thickness dimension to a lesser thickness dimension located proximal said perimeter.
