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.

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; a side wall extending between the crown and the sole; a hosel extending from the crown and including a shaft bore; and a face defining a ball-striking surface and intersecting the transmittal portion at a leading edge, wherein the flexure is spaced aftward of the ball-striking surface by the transmittal portion, and comprises a front wall, an apex and a rear wall, wherein the front wall extends into a cavity defined by the golf club head and the rear wall extends into the cavity and the front wall and the rear wall are coupled at the apex, wherein the flexure is spaced from the ball-striking surface by a distance that is between 20% and 50% of a CG-Z-fc distance between the geometric face center of the golf club head and the center of gravity of the golf club head along a horizontal Z-axis that extends from the front to the aft of the golf club head, and wherein the CG-Z-fc distance is at least 33.0 mm and the moment-of-inertia about a vertical axis extending through the center-of-gravity is at least 450 kg-mm2.
