Abstract

A golf club head including a crown, a sole, a hosel, a face and a flexure. The golf club head includes a multi-material construction including a face member, a midsection and an aft member that allows optimization of the mass distribution of the golf club head. The flexure provides compliance during an impact between the golf club head and a golf ball.

First claim

We claim:

1. A golf club head, comprising:
a front hitting cup including a face that defines a ball-striking surface, and a hosel that extends away from a heel portion of the hitting cup;
an aft cup; and
a tubular midsection that extends between and couples the front hitting cup and the aft cup, wherein the midsection is constructed of a material that is different than a material of the front hitting cup and a material of the aft cup,
wherein at least a portion of the front hitting cup and the midsection form a crown and a sole, wherein the crown defines an upper surface of the golf club head, and the sole defines a lower surface of the golf club head, the sole comprising a transmittal portion, a flexure and a rear portion,
wherein the transmittal portion extends between the face and the flexure such that the flexure is spaced aftward of the ball-striking surface by the transmittal portion, and
wherein the flexure is formed at least partially in the hitting cup and at least partially in the midsection 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.

2. The golf club head of claim 1 , wherein the material of the midsection has a lower specific gravity than the material of the aft cup.

3. The golf club head of claim 1 , wherein the material of the midsection has a lower specific gravity than the material of the front hitting cup.

4. The golf club head of claim 1 , further comprising a bridge member extending between the front hitting cup and the aft cup.

5. The golf club head of claim 4 , wherein the bridge member is disposed at a skirt portion of the golf club head.

6. A golf club head, comprising:
a front hitting cup including a face that defines a ball-striking surface, and a hosel that extends away from a heel portion of the hitting cup;
an aft cup; and
a tubular midsection that extends between and couples the front hitting cup and the aft cup, wherein the midsection is constructed of a material that is different than a material of the front hitting cup and a material of the aft cup,
wherein at least a portion of the front hitting cup and the midsection form a crown and a sole, wherein the crown defines an upper surface of the golf club head, and the sole defines a lower surface of the golf club head, the sole comprising a transmittal portion, a flexure and a rear portion,
wherein the transmittal portion extends between the face and the flexure such that the flexure is spaced aftward of the ball-striking surface by the transmittal portion, and
wherein the flexure is formed entirely in the midsection 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.

7. The golf club head of claim 6 , wherein the material of the midsection has a lower specific gravity than the material of the aft cup.

8. The golf club head of claim 6 , wherein the material of the midsection has a lower specific gravity than the material of the front hitting cup.

9. The golf club head of claim 6 , further comprising a bridge member extending between the front hitting cup and the aft cup.

10. The golf club head of claim 9 , wherein the bridge member is disposed at a skirt portion of the golf club head.
