Abstract
An iron-type golf club head includes a ball striking face and a rear weight member that are engaged through one or more resilient members with a connection structure that creates a mass-damping effect at impact with a golf ball.
Claims15
An iron-type golf club head, comprising:
- a ball striking face member including a rear surface and a ball striking face;
- a rear weight member including a front surface,
- at least one resilient member between the front surface of the rear weight member and the rear surface of the ball striking face member,
- wherein the front surface of the rear weight member and the rear surface of the ball striking face member face one another and define a space therebetween;
- wherein the at least one resilient member is disposed within the space,
- wherein the ball striking face member comprises a first material having a first hardness,
- wherein the rear weight member comprises a second member having a second hardness, and
- wherein the at least one resilient member comprises at least a third hardness,
- wherein no portion of the at least one resilient member comprises a hardness greater than any portion of the ball striking face member or rear weight member;
- wherein the hardness of the at least one resilient member is varied;
- wherein the rear surface of the ball striking face member comprises an engagement member,
- wherein the engagement member comprises a raised rib element formed as part of the ball striking face member,
- wherein the raised rib element projects rearward from the rear surface of the ball striking face member,
- wherein the raised rib element extends from a toe portion of the ball striking face member to a heel portion of the ball striking face member,
- wherein the at least one rear weight member and varied hardness of the at least one resilient member are configured to receive transferred energy from impact between the face member and a ball, and to selectively limit compressibility of the space between the ball striking face member and the rear weight member and divide the space into:
- (a) an area of low compressibility located above the raised rib element, and (b) an area of high compressibility located below the raised rib element,
- wherein the raised rib element is arranged with respect to a center of gravity of the golf club head such that the raised rib element passes through the center of gravity of the iron type golf club head.
