GOLF CLUB HEAD WITH PROGRESSIVE FACE STIFFNESS
First Claim
Patent Images
1. A golf club head, comprising:
- a face, a crown, a sole, and a skirt coupled together to form a club head body having an interior volume, wherein the face has a striking surface and an inner surface opposite the striking surface; and
a patch coupled to the inner surface of the face within the interior volume, wherein the face has a point of maximum coefficient of restitution between the crown and a geometric center of the face.

Abstract
A metal wood golf club head adapted for attachment to a shaft, with a body comprising of a first body portion and a second body portion, each portion constructed of a different density material. Combining a high density material in the first body portion with a low density material in the second body portion, creates an ultra-low center of gravity relative to the geometric face center, resulting in higher launch angles and spin rate ratios. Thickening the lower area of the front face lowers the center of gravity and upwardly shifts the coefficient of restitution to the geometric center of the face.

14. A golf club head, comprising:
-
a face, a crown, a sole, and a skirt coupled together to form a club head body having an interior volume, wherein the face has a striking surface and an inner surface opposite the striking surface; and a patch coupled to the inner surface of the face within the interior volume, wherein the patch creates a preferred striking zone on the face, wherein the preferred striking zone is located on an upper half of the striking surface and has a greater coefficient of restitution range than the rest of the face. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A golf club head, comprising:
-
a face, a crown, a sole, and a skirt coupled together to form a club head body having an interior volume, wherein the face has a striking surface and an inner surface opposite the striking surface; and a patch coupled to the inner surface, wherein the patch has a first thickness at a lower portion adjacent the sole and a second thickness at an upper portion, wherein the first thickness is greater than the second thickness, wherein the face has a substantially uniform thickness, wherein the face has a point of maximum coefficient of restitution above the geometric center of the face, and wherein an area on the face between the sole and the geometric center has a coefficient of restitution that is less than the point of maximum coefficient of restitution. - View Dependent Claims (22, 23)
