Abstract
A ball striking device, such as a golf club head, has a face member with a striking surface configured for striking a ball and a flange that comprises a portion of the crown. The flange being made of at least two members that are made of different materials, where a second material has a lower modulus of elasticity than the first material. The second member has a length, a width, a thickness and a location proximate to the ball striking surface to improve the impact efficiency of a collision with a golf ball.
Claims20
A golf club head, comprising:
- a club head body comprising a heel, a toe, a crown, and a rear;
- and
- a face member comprising a striking face, a first member, and a second member;
- wherein the first member comprises a first material and the second member comprises a second material;
- wherein the first member comprises a portion of the strike face and a flange, the flange comprising a portion of the crown;
- wherein the flange further comprises an opening extending through the flange;
- wherein the second member is contained within the flange and spans the opening;
- wherein the club head body and the face member are coupled to each other;
- wherein a width of the second member measured in a front-to-back direction varies in width such that the width of the second member increases in a direction from a center of the flange towards the heel and toe;
- a head breadth;
- wherein the head breadth is measured as a distance from a club head forwardmost plane to a club head rearwardmost plane;
- wherein the forwardmost plane intersects a first outermost point on the striking face and the rearwardmost plane intersects a second outermost point on the rear.
- wherein the forwardmost plane and the rearwardmost plane are parallel;
- wherein a ratio of a second member center width to the head breadth is between 1:26 and 1:8.
