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.
Claims16
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.
