Golf club head with flexure
First Claim
Patent Images
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;
a side wall extending between the crown and sole;
a hosel extending from the crown and including a shaft bore;
a face defining a ball-striking surface and intersecting the lower surface at a leading edge; and
a flexure that is a tubular member interposed between a face portion and a rear body portion of the golf club head so that it forms an intermediate ring that is spaced aftward of the ball-striking surface,wherein the sole is constructed of a first material having a first Young'"'"'s modulus and the flexure is constructed of a second material having a second Young'"'"'s modulus that is lower than the first Young'"'"'s modulus,wherein the flexure is tuned so that the width across the flexure in a face-to-aft direction varies sinusoidally, immediately after impact, at a frequency of about 2900 Hz to about 4000 Hz, andwherein at least a portion of the flexure is constructed of a β
-Ti alloy.

Abstract
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. The flexure is tuned to vibrate, immediately after impact, at a predetermined frequency.

11. 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; a side wall extending between the crown and sole; a hosel extending from the crown and including a shaft bore; a face defining a ball-striking surface and intersecting the lower surface at a leading edge; and a flexure component that is spaced afterward of the ball-striking surface, extending in a generally heel-to-toe direction and parallel to the leading edge of the golf club head, wherein the flexure component is coupled to a forward flange and an aft flange of the golf club head, wherein the forward flange and the aft flange are angled toward each other, wherein the sole is constructed of a first material having a first Young'"'"'s modulus and the flexure is constructed of a second material having a second Young'"'"'s modulus that is lower than the first Young'"'"'s modulus, wherein the flexure component is tuned so that the width across the flexure component in a face-to-aft direction varies sinusoidally, immediately after impact, at a frequency wherein at least a portion of the flexure component is constructed of a β
-Ti alloy, andwherein the flexure component extends across the body in a generally heel-to-toe direction and within between about 5.0 mm and about 20.0 mm from the leading edge of the golf club head.

12. 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; a side wall extending between the crown and sole; a hosel extending from the crown and including a shaft bore; a face defining a ball-striking surface and intersecting the lower surface at a leading edge; and a flexure component that is spaced aftward of the ball-striking surface, extending in a generally heel-to-toe direction and parallel to the leading edge of the golf club head, wherein the flexure component is coupled to a forward flange and an aft flange of the golf club head, wherein the flexure component is corrugated, wherein the sole is constructed of a first material having a first Young'"'"'s modulus and the flexure is constructed of a second material having a second Young'"'"'s modulus that is lower than the first Young'"'"'s modulus, wherein the flexure is tuned so that the width across the flexure in a face-to-aft direction varies sinusoidally, immediately after impact, at a frequency of about 2900 Hz to about 4000 Hz, wherein at least a portion of the flexure component is constructed of a β
-Ti alloy, andwherein the flexure component extends across the body in a generally heel-to-toe direction and within between about 5.0 mm and about 20.0 mm from the leading edge of the golf club head.
