Golf club striking plate having elliptical regions of thickness
First Claim
Patent Images
1. A wood-type golf club head comprising:
- a body having a crown, a sole, a heel end, a toe end, and a striking plate comprising a central elliptical region having an uniform base thickness ranging from 0.122 inch to 0.117 inch, a first concentric elliptical region encompassing the central elliptical region, the first concentric elliptical region having an uniform first thickness ranging from 0.117 inch to 0.112 inch wherein the base thickness is greater than the first thickness, a second concentric elliptical region having an uniform second thickness ranging from 0.112 inch to 0.100 inch wherein the first thickness is greater than the second thickness, a third concentric region having an uniform third thickness ranging from 0.100 inch to 0.085 inch wherein the second thickness is greater than the third thickness, and a periphery region having a fourth thickness wherein the fourth thickness is less than the third thickness;
wherein the thickness of each of the elliptical regions of the striking plate is assigned according to the probability of impacts with a golf ball wherein the central elliptical region has the highest probability of impacts with a golf ball and is the thickest elliptical region of the elliptical regions of the striking plate.

Abstract
A golf club head having a striking plate with concentric elliptical regions of varying thickness ranges is disclosed herein. A central elliptical region has a base thickness range that is thicker than the thickness range of any of the other elliptical regions. The thickness of the elliptical regions decreases outward from the center. The striking plate may be used on a wood-type golf club head or an iron-type golf club head. The striking plate is preferably composed of steel or titanium. The elliptical regions correspond to golf ball impact probability points on the striking plate.
