Abstract
A golf club head includes a resilient member extending from a sole of the club head to the crown. The resilient member has a convex, arcuate shape relative to a strike face of the club. The resilient member has a rest state prior to impact with a golf ball, in which the resilient member defines a first chord length, and a deflected state during impact with a golf ball, in which the resilient member defines a second chord length that is greater than the first chord length. The resilient member improves impact response of the strike face to allow strike face thickness to be reduced while maintaining durability of the golf club head.
Claims16
A golf club head comprising:
- a strike face comprising a striking surface for impacting a golf ball;
- a body comprising a crown, a sole, a heel, a toe, and a rear end, wherein the strike face and body are coupled together to enclose an interior cavity;
- and
- a resilient member disposed in the interior cavity and extending between the crown and the sole;
- wherein the resilient member is spaced rearwardly of the strike face by an offset distance from 0.5 inch to 1.0 inch;
- wherein the resilient member comprises a first end, coupled to the crown, a second end, coupled to the sole, and an integral hinge therebetween;
- the integral hinge comprises a first hinge leg and a second hinge leg that define an included angle from 10 degrees to 80 degrees;
- wherein the resilient member comprises a substantially curvilinear shape;
- and
- wherein the resilient member is integrally formed with the body.
A golf club head comprising:
- a strike face comprising a striking surface for impacting a golf ball;
- a body comprising a crown, a sole, a heel, a toe, and a rear end, wherein the strike face and body are coupled together to enclose an interior cavity;
- and
- a resilient member disposed in the interior cavity and extending between the crown and the sole;
- wherein the resilient member is spaced rearwardly of the strike face by an offset distance from 0.5 inch to 1.0 inch;
- wherein the resilient member comprises a first end, coupled to the crown, a second end, coupled to the sole, and an integral hinge therebetween;
- the integral hinge comprises a first hinge leg and a second hinge leg that define an included angle between 10 and 80 degrees;
- wherein the resilient member comprises a substantially curvilinear shape;
- and
- wherein the resilient member is mechanically attached to the golf club head.
A golf club head, comprising:
- a body comprising a crown, a sole, a heel, a toe, and a rear;
- a strike face coupled to the body to define an interior cavity, the strike face comprising a striking surface for impacting a golf ball and defining a face center;
- an x-axis extending horizontally through the face center in a direction from the heel to the toe;
- a y-axis perpendicular to the x-axis and extending vertically through the face center in a direction from the sole to the crown;
- a z-axis perpendicular to the x-axis and the y-axis, and extending horizontally through the face center in a direction from the strike face to the rear;
- a resilient member disposed in the interior cavity and having a first end attached to the crown, a second end attached to the sole, and an integral hinge therebetween:
- the integral hinge comprises a first hinge leg and a second hinge leg that define an included angle between 10 and 80 degrees;
- wherein the resilient member is spaced rearwardly of the strike face by an offset distance from 0.5 inch to 1.0 inch;
- and
- the resilient member comprising a curvilinear shape, wherein the curvilinear shape, when viewed in an YZ-plane defined by the y-axis and the z-axis, is concave relative to the strike face.
