Abstract

Claims (35)

1 . A golf club comprising a club head having a club head mass and:

a y-axis extending vertically through a face center of the club head and a Moment of Inertia about the y-axis,

a body comprising a heel, a toe, a topline, a sole, and a hosel;

a back wall coupled to the body;

a face insert formed of titanium and having a face insert mass, the face insert having a face insert thickness at the face center, the face insert being coupled to the body to form a hollow cavity between the face insert and the back wall;

a toe weight member formed of tungsten and is coupled in a lower, toe portion of the hollow cavity and has a toe weight member mass that comprises greater than 25% of the club head mass; and

a heel weight member formed of tungsten and coupled in a hosel cavity of the body such that a shaft axis of the hosel intersects the heel weight member below the hosel; and

wherein the face insert mass is less than the toe weight member mass.

2 . The golf club of claim 1 , wherein the face insert thickness of between 2 mm and 2.5 mm.

3 . The golf club of claim 1 , wherein the heel weight member comprises between 5% and 10% of the club head mass.

4 . The golf club of claim 1 , wherein the Moment of Inertia about the y-axis is greater than 230 kg-mm 2 .

5 . The golf club of claim 1 , wherein the Moment of Inertia about the y-axis is greater than 280 kg-mm 2 .

6 . The golf club of claim 5 , wherein the club head has a Moment of Inertia about a shaft axis that is between 610 kg-mm 2 and 700 kg-mm 2 .

7 . The golf club of claim 1 , wherein the club head further comprises a second heel weight member that is coupled in a heel side of the hollow cavity.

8 . A golf club comprising a club head having a club head mass and:

a y-axis extending vertically through a face center of the club head and a Moment of Inertia about the y-axis,

a body comprising a heel, a toe, a topline, a sole, and a hosel;

a back wall coupled to the body;

a face insert formed of titanium and having a face insert mass, the face insert having a face insert thickness at the face center, the face insert being coupled to the body to form a hollow cavity between the face insert and the back wall;

a toe weight member formed of tungsten and is coupled in a lower, toe portion of the hollow cavity and has a toe weight member mass that comprises greater than 25% of the club head mass; and

a heel weight member formed of tungsten and coupled in a hosel cavity of the body such that a shaft axis of the hosel intersects the heel weight member below the hosel;

wherein the face insert mass is less than the toe weight member mass; and

wherein the body includes a body insert groove and a body insert tongue and the face insert has a face insert tongue that fits within the body insert groove and the face insert has a face insert groove that couples to the body insert tongue.

9 . A golf club comprising a club head having a club head mass and:

a y-axis extending vertically through a face center of the club head and a Moment of Inertia about the y-axis,

a body made of steel comprising a heel, a toe, a topline, a sole, and a hosel;

a back wall coupled to the body,

a face insert formed of titanium and having a face insert mass, the face insert being brazed to the body to form a hollow cavity between the face insert and the back wall;

a toe weight member is formed of tungsten and is coupled in a lower, toe portion of the hollow cavity and has a toe weight member mass that comprises greater than 25% of the club head mass;

wherein the face insert mass is less than the toe weight member mass;

a heel weight member is formed of tungsten and is coupled in a hosel cavity of the body such that it is intersected by a shaft axis of the club head; and

a second heel weight member is formed of tungsten and is coupled in a lower, heel portion of the hollow cavity.

10 . The golf club of claim 9 , wherein the Moment of Inertia about the y-axis is greater than 280 kg-mm 2 .

11 . The golf club of claim 10 , wherein the club head has a Moment of Inertia about a shaft axis that is between 610 kg-mm 2 and 700 kg-mm 2 .

12 . The golf club of claim 9 , wherein the face insert mass is less than ½ the toe weight member mass.
