GOLF CLUB HEAD WITH FLEXURE

摘要

A golf club head including a crown, a sole, a hosel, a face and a flexure. The flexure provides compliance during an impact between the golf club head and a golf ball, and is tuned to vibrate, immediately after impact, at a predetermined frequency. A slot is included in a portion of the golf club head and works with the flexure to further tune performance.

主权项

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, wherein the transmittal portion includes an elongate slot defining an aperture that extends through the sole; a side wall extending between the crown and the sole; a hosel extending from the crown and including a shaft bore; a face defining a front ball-striking surface and a back surface, the face intersecting the transmittal portion at a leading edge; and a cover extending at least partially across the flexure in a fore-aft direction, wherein the cover is a separate component that is coupled to the sole, wherein the golf club head defines an origin at a location on a shaft axis defined by the shaft bore in a plane defined by the proximal end of the hosel, an x-axis extending from the origin in a heel to toe direction and parallel to a plane that is tangent to the face at a geometric face center of the ball-striking surface, a y-axis extending vertically through the origin and perpendicular to a ground plane when the golf club head is in an address position on the ground plane, and a z-axis extending in a face to aft direction parallel to the ground plane when the golf club head is in an address position, wherein the flexure is spaced aftward of the ball-striking surface by the transmittal portion, and comprises a front wall, wherein the front wall extends into a cavity defined by the golf club head, and wherein the elongate slot intersects a vertical plane parallel to the y-axis and the z-axis and extending through the geometric face center of the ball-striking surface.
