Golf club head with flexure
First Claim
Patent Images
1. A golf club head, comprising:
- a crown defining an upper surface of the golf club head;
a sole defining a lower surface of the golf club head, comprising a transmittal portion, a flexure and a rear portion;
a side wall extending between the crown and the sole;
a hosel extending from the crown and including a shaft bore; and
a face defining a ball-striking surface and intersecting the transmittal portion at a leading edge,wherein the flexure is spaced aftward of the ball-striking surface by the transmittal portion, and comprises a front wall, an apex and a rear wall, wherein the front wall extends into a cavity defined by the golf club head and the rear wall extends into the cavity and the front wall and the rear wall are coupled at the apex,wherein the thickness of the apex is different from the greater of the thickness of the front wall and the thickness of the rear wall by less than 30%,wherein the face comprises an outer layer forming a portion of the ball striking surface, a back layer and a chip insert, and the outer layer and back layer are coupled and define an enclosed cavity and the chip insert is disposed in the enclosed cavity, andwherein the face has a Face Thickness Ratio of less than about 0.875, wherein the Face Thickness Ratio is defined as a thickness of the outer layer at the geometric face center divided by a thickness of the backing layer at the geometric face center.
