Abstract

Golf club heads with cavities and inserts, and methods to manufacture golf club heads with cavities. Various embodiments include a golf club head comprising a body. The body comprises a strikeface at a front of the golf club head, a backface opposite the strikeface, a heel region, a toe region opposite the heel region, a sole, a rear portion at a rear of the golf club head, and a cavity located between the backface and the rear portion. In many embodiments, the body further comprises an insert within the cavity.

Claims

1. A golf club head comprising:

a body comprising;

a strikeface at a front of the golf club head;

a backface opposite the strikeface;

a heel region;

a toe region opposite the heel region;

a sole;

a rear portion at a rear of the golf club head; and

a cavity located between the backface and the rear portion comprising;

a side wall offset from the backface;

a bottom wall; and

a divider comprising an aperture, wherein the divider is parallel with the side wall of the cavity and extends from the bottom wall of the cavity along the entire length of the cavity from the heel region to the toe region thereby separating the cavity into a first pocket and a second pocket;

and

an insert received within the cavity;

wherein;

the insert comprises;

a first component having one aperture;

a second component having one aperture that is concentric with the one aperture of the first component;

a slit separating the first component and the second component; and

a base;

the base of the insert is adjacent the bottom wall of the cavity;

the first pocket is adjacent the side wall of the cavity;

the second pocket is opposite the first pocket; and

the first component and the second component abut the divider.

2. The golf club head of claim 1, wherein the first component is positioned within the second pocket of the cavity and the second component is positioned within the first pocket of the cavity.

3. The golf club head of claim 1, wherein the one aperture of the first component, and the one aperture of the second component is concentric with the aperture of the divider of the cavity.

4. The golf club head of claim 3, wherein the one aperture of the first component, the one aperture of the second component, and the aperture of the divider receives a fastener.

5. The golf club head of claim 1, wherein a width of the slit is constant extending from the base of the insert into a portion of the insert.

6. The golf club head of claim 1, wherein a width of the slit varies extending from the base of the insert into a portion of the insert.

7. The golf club head of claim 1, wherein the first component comprises a mass less than the second component.

8. The golf club head of claim 1, wherein the first component comprises a mass greater than the second component.

9. The golf club head of claim 1, wherein the first component comprises a different material from the second component.

10. The golf club head of claim 1, wherein the first component and the second component comprise a metal selected from the group consisting of tungsten, aluminum, titanium, vanadium, chromium, cobalt, and nickel.

11. A golf club head comprising:

a body comprising;

a strikeface at a front of the golf club head;

a backface opposite the strikeface;

a heel region;

a toe region opposite the heel region;

a sole;

a rear portion at a rear of the golf club head; and

a cavity located between the backface and the rear portion comprising;

a side wall offset from the backface;

a bottom wall; and

a divider comprising an aperture, wherein the divider is perpendicular with the side wall of the cavity and extends from the side wall of the cavity along the entire length of the cavity from the heel region to the toe region thereby separating the cavity into a first pocket and a second pocket;

and

an insert received within the cavity;

wherein;

the insert comprises;

a first component having one aperture;

a second component having one aperture that is concentric with the one aperture of the first component;

a slit separating the first component and the second component; and

a front surface;

the front surface of the insert is adjacent the side wall of the cavity;

the first pocket is adjacent the bottom wall of the cavity;

the second pocket is opposite the first pocket; and

the first component and the second component abut the divider.

12. The golf club head of claim 11, wherein the first component is positioned within the second pocket of the cavity and the second component is positioned within the first pocket of the cavity.

13. The golf club head of claim 11, wherein the one aperture of the first component, and the one aperture of the second component is concentric with the aperture of the divider of the cavity.

14. The golf club head of claim 13, wherein the one aperture of the first component, the one aperture of the second component, and the aperture of the divider receives a fastener.

15. The golf club head of claim 11, wherein a width of the slit is constant extending from the front surface of the insert into a portion of the insert.

16. The golf club head of claim 11, wherein a width of the slit varies extending from the front surface of the insert into a portion of the insert.

17. The golf club head of claim 11, wherein the first component comprises a mass less than the second component.

18. The golf club head of claim 11, wherein the first component comprises a mass greater than the second component.

19. The golf club head of claim 11, wherein the first component comprises a different material from the second component.

20. The golf club head of claim 11, wherein the first component and the second component comprise a metal selected from the group consisting of tungsten, aluminum, titanium, vanadium, chromium, cobalt, and nickel.
