Method and apparatus for elastic tailoring of golf club impact
A method and apparatus for beneficially controlling the impact between a club head and a golf ball are described. A golf club head (such as on a driver, iron, or putter) has a body and a face mechanically supported thereon, wherein the face and body are elastically tailored to create beneficial face motion and deformation at impact. The tailored clubhead compliance is shown to influence impact properties and resulting ball parameters such as speed, direction and spin rates resulting from the impact event between the face of the club and the golf ball. Several embodiments are presented for controlling ball spin through design of the elastic and dynamic response of the face and body under impact loading.
1. A golf club iron head having a ball hitting face and a body defined by a top, a sole, a toe, a heel and a rear surface; the head comprising a metal face being elastically supported relative to said body for tangential motion in a selected direction relative to a plane parallel to said ball hitting face in response to impact of said head with a golf ball;
wherein said face is supported by a plurality of elastic mounts.
2. A golf club iron head having a ball hitting face and a body defined by a top, a sole, a toe, a heel and a rear surface; the head comprising a metal face being elastically supported relative to said body for tangential motion in a selected direction relative to a plane parallel to said ball hitting face in response to impact of said head with a golf ball;
wherein said face is supported by at least one elastic motion mount on an elongated beam.
3. The golf club head recited in claim 2 wherein said beam has a varying thickness along its length.
4. The golf club head recited in claim 3 wherein said beam is thinner at its center than at its ends.
5. A golf club iron head having a ball hitting face and a body defined by a top, a sole, a toe, a heel and a rear surface; the head comprising a metal face being elastically supported relative to said body for tangential motion in a selected direction relative to a plane parallel to said ball hitting face in response to impact of said head with a golf ball;
wherein said face is supported on a plurality of elastic mounts supported on a folded beam extending to said rear surface of said body.
