Abstract

A golf club head with improved striking face is disclosed. More specifically, the present invention relates to a golf club head wherein the striking face is further comprised out of a thickened central region, located near a geometric center of the striking face portion, a central transition region extending outward radially from the thickened central region, a thinned intermediate region, extending outward radially from the central transition region, a thickened stress reducing region, extending outward radially from the thinned intermediate region, and a thinned perimeter region, extending outward radially from the thickened stress reducing region, all of which combine to form the improved striking face.

First claim

What is claimed is:

1 . A golf club head comprising:
a striking face portion, located at a frontal portion of said golf club head, adapted to impact a golf ball; and a body portion, attached to a rear of said striking face portion, wherein said striking face portion further comprises;
a frontal striking surface, wherein said frontal striking surface is substantially planar, and
an internal rear surface,
wherein said frontal striking surface and said internal rear surface combine to further comprise;
a thickened central region, located near a geometric center of said striking face portion, having a first thickness,
 said first thickness measures a thickness of said striking face portion between said frontal striking surface and said internal rear surface,
a central transition region, extending outward radially from said thickened central region, having a variable thickness,
 said variable thickness measures a thickness of said striking face portion between said frontal striking surface and said internal rear surface,
a thinned intermediate region, extending outward radially from said central transition region, having a third thickness,
 said third thickness measures a thickness of said striking face portion between said frontal striking surface and said internal rear surface,
a thickened stress reducing region, extending outward radially from said thinned intermediate region, having a fourth thickness,
 said fourth thickness measures a thickness of said striking face portion between said frontal striking surface and said internal rear surface, and
a thinned perimeter region, extending outward radially from said thickened stress reducing region, having a fifth thickness,
 said fifth thickness measures a thickness of said striking face portion between said frontal striking surface and said internal rear surface,

wherein said thickened stress reducing region forms a ring protruding rearward from said internal rear surface of said striking face portion, and wherein said fourth thickness is greater than said first thickness.

2 . The golf club head of claim 1 , wherein said fourth thickness of said thickened stress reducing region is a thickest portion of said striking face portion.

3 . The golf club head of claim 2 , wherein said fifth thickness is greater than said third thickness.

4 . The golf club head of claim 1 , wherein said thickened stress reducing region has a T over H Ratio of between about 0.6 to about 1.1, said T over H ratio defined as;

5 . The golf club head of claim 4 , wherein said T over H ratio is between about 0.7 to about 0.9.

6 . The golf club head of claim 5 , wherein said T over H ratio is about 0.8.

7 . The golf club head of claim 4 , wherein said thickened stress reducing region further comprises;
an upper thickened stress reducing region, and a lower thickened stress reducing region, wherein said upper thickened stress reducing region and said lower thickened stress reducing region has a same height.

8 . The golf club head of claim 4 , wherein said thickened stress reducing region further comprises;
an upper thickened stress reducing region, and a lower thickened stress reducing region, wherein said upper thickened stress reducing region and said lower thickened stress reducing region has a different height.

9 . The golf club head of claim 8 , wherein a height of said upper thickened stress reducing region is smaller than a height of said lower thickened stress reducing region.

10 . The golf club head of claim 9 , wherein said height of said upper thickened stress reducing region is about 0.5 mm smaller than said height of said lower thickened stress reducing region.

11 . A golf club head comprising:
a striking face portion, located at a frontal portion of said golf club head, adapted to impact a golf ball; and a body portion, attached to a rear of said striking face portion, wherein said striking face portion further comprises;
a frontal striking surface, wherein said frontal striking surface is substantially planar, and
an internal rear surface,
wherein said frontal striking surface and said internal rear surface combine to further comprise;
a thickened central region, located near a geometric center of said striking face portion, having a first thickness,
 said first thickness measures a thickness of said striking face portion between said frontal striking surface and said internal rear surface,
a central transition region, extending outward radially from said thickened central region, having a variable thickness,
 said variable thickness measures a thickness of said striking face portion between said frontal striking surface and said internal rear surface,
a thinned intermediate region, extending outward radially from said central transition region, having a third thickness,
 said third thickness measures a thickness of said striking face portion between said frontal striking surface and said internal rear surface,
a thickened stress reducing region, extending outward radially from said thinned intermediate region, having a fourth thickness,
 said fourth thickness measures a thickness of said striking face portion between said frontal striking surface and said internal rear surface, and
a thinned perimeter region, extending outward radially from said thickened stress reducing region, forming an indentation in said internal rear surface, having a fifth thickness,
 said fifth thickness measures a thickness of said striking face portion between said frontal striking surface and said internal rear surface,

wherein said thickened stress reducing region forms a ring protruding rearward from said internal rear surface of said striking face portion, wherein said fifth thickness is less said fourth thickness, and wherein said third thickness of said thinned intermediate region is a thinnest po
