Abstract

A golf club head includes a body having a face plate having a strike surface and an opposing interior surface, a rear end, and a sole connecting the faceplate with the rear end. The face plate, the rear end, and the sole partially define a cavity. An insert is positioned within the cavity, the insert presenting an insert surface facing the interior surface of the face plate and spaced therefrom.

Claims

1. A golf club head comprising:

a body including;

a face plate having a strike surface and an opposing interior surface,

wherein a distance between the strike surface and the opposing interior surface of the face plate defines a thickness of the face plate,

and the thickness of the face plate is uniform;

a rear end; and

a sole connecting the face plate with the rear end, wherein the opposing interior surface of the face plate, an interior surface of the rear end, and an interior surface of the sole partially define a cavity; and

an insert positioned within the cavity, the insert comprising;

a first end configured to contact the entire interior surface of the sole;

a second end opposite the first end; and

a front portion configured to face the opposing interior surface of the face plate, the

front portion having;

a first insert surface in contact with the opposing interior surface of the face plate and positioned between the first end and the second end; and

a second insert surface positioned adjacent and offset from the first insert surface;

wherein the second insert surface is spaced apart from the opposing interior surface of the face plate defining a distance between the second insert surface and the opposing interior surface of the face plate; and

wherein the distance between the second insert surface and the opposing interior surface of the face plate ranges from 0.005-0.060 inch.

2. The golf club head of claim 1, wherein the second insert surface includes a taper angle such that the distance between the second insert surface and the opposing interior surface of the face plate, in a direction normal to the second insert surface, increases from near the first end to the second end.

3. The golf club head of claim 2, wherein the taper angle is between 0.01°

-20°

.

4. The golf club head of claim 1, wherein the second insert surface is concave relative to the face plate in a direction extending from near a bottom surface of the insert to near a top surface of the insert, and in a direction extending from near a heel end of the insert to near a toe end of the insert.

5. The golf club head of claim 4, wherein the first insert surface is a U-shape comprising:

a cross-member extending from the heel end of the insert to the toe end of the insert, adjacent to the bottom surface; and

a first arm adjacent to the heel end of the insert and a second arm adjacent to the toe end of the insert, the first and second arms extending at least partially from the bottom surface of the insert to the top surface of the insert.

6. The golf club head of claim 1, wherein the first insert surface is in contact with 0.5-10% of the opposing interior surface of the face plate within the cavity.

7. The golf club head of claim 1, wherein the face plate is configured to deform towards the rear end during impact with a golf ball, and further wherein the first insert surface is configured to limit travel of the face plate during impact.

8. The golf club head of claim 1, wherein the face plate is configured to deform towards the rear end during impact with a golf ball, wherein the face plate does not contact the second insert surface of the insert during impact.

9. The golf club head of claim 1, wherein the sole of the club head comprises a uniform thickness less than 0.060 inch.

10. A golf club head comprising:

a body including;

a face plate having a strike surface and an opposing interior surface,

wherein a distance between the strike surface and the opposing interior surface of the face plate defines a thickness of the face plate,

and the thickness of the face plate is uniform;

a rear end; and

a sole connecting the face plate with the rear end, wherein the opposing interior surface of the face plate, an interior surface of the rear end, and an interior surface of the sole partially define a cavity; and

an insert positioned within the cavity, the insert comprising;

a first end configured to contact the entire interior surface of the sole;

a second end opposite the first end; and

a front portion configured to face the opposing interior surface of the face plate, the

front portion having;

a first insert surface having one or more ribs or protrusions in contact with the opposing interior surface of the face plate and positioned between the first end and the second end; and

a second insert surface positioned adjacent and offset from the first insert surface, wherein the second insert surface is spaced apart from the opposing interior surface of the face plate;

wherein a distance between the second insert surface and the opposing interior surface of the face plate ranges from 0.005-0.060 inch.

11. The golf club head of claim 10, wherein the second insert surface includes a taper angle such that the distance between the second insert surface and the opposing interior surface of the face plate, in a direction normal to the second insert surface, increases from near the first end to the second end.

12. The golf club head of claim 11, wherein the taper angle is between 0.01°

-20°

.

13. The golf club head of claim 10, wherein the second insert surface is concave relative to the face plate in a direction extending from near a bottom surface of the insert to near a top surface of the insert, and in a direction extending from near a heel end of the insert to near a toe end of the insert.

14. The golf club head of claim 13, wherein the first insert surface comprises a first arm adjacent to the heel end of the insert and a second arm adjacent to the toe end of the insert, the first and second arms extending at least partially from the bottom surface of the insert to the top surface of the insert.

15. The golf club head of claim 10, wherein the first insert surface is in contact with 0.5-10% of the opposing interior surface of the face plate within the cavity.

16. The golf club head of claim 10, wherein the sole of the club head comprises a uniform thickness less than 0.060 inch.
