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;
said face having a strike surface and an inner surface opposite said strike surface, said face having a point of maximum coefficient of restitution and a geometric center; and
a coefficient of restitution lowering insert coupled to said inner surface of said face within said interior volume;
wherein said point of maximum coefficient of restitution is between said crown and said geometric center.

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.

18. A wood-type golf club head, comprising:
-
a face with a strike surface and an inner surface opposite said strike surface, said face having a non-uniform coefficient of restitution; and
an insert coupled to a portion of said inner surface;
wherein said insert stiffens said face in and around said portion, lowering the coefficient of restitution thereof below a predetermined value. - View Dependent Claims (19, 20, 21)
