Golf club head with variable face thickness
First Claim
1. A driver-type golf club head comprising:
- a body having a crown, a sole, and a hollow interior; and
a face disposed on the body,wherein the face comprises a central region having a first perimeter with an elliptical shape and a first average thickness,wherein the face comprises an outer edge defining a perimeter where the face contacts the body, the outer edge having a non-elliptical shape,wherein the face comprises a first intermediate region located between the central region and the outer edge, the first intermediate region having a second perimeter with a second average thickness that is less than the first average thickness,wherein the face comprises a second intermediate region located between the first intermediate region and the outer edge, the second intermediate region having a third perimeter with a shape approximately the same as the shape of the outer edge and having a third average thickness that is less than the second average thickness,wherein the face comprises a third intermediate region between the second intermediate region and the outer edge, the third intermediate region having a fourth perimeter with a shape that is approximately the same as the shape of the outer edge and having a fourth average thickness that is less than the third average thickness,wherein the golf club head has a volume of 385 to 475 cubic centimeters and a mass of 170 to 250 grams, andwherein the face is composed of a titanium material.
