Abstract

A golf club head comprising a conformal weight sized to fit within a recess or channel disposed in a crown or sole is disclosed herein. In some embodiments, the crown or sole itself is a conformal weight, and is removably affixed to a base structure comprising a striking face and a skeletal support structure. In other embodiments, the golf club head comprises a conformal weight in the form of a sole cap that is removably affixed to the golf club head and covers small weight ports disposed in the sole.

Claims

1. A golf club head comprising:

a base structure comprising a striking face and a skeletal support structure extending away from the striking face;

a crown composed of a lightweight material; and

a sole composed of the lightweight material,

wherein the skeletal support structure comprises at least one shallow weight port,

wherein at least one of the crown and the sole comprises a protrusion extending from an internal surface,

wherein the protrusion at least partially fills the at least one shallow weight port, further comprising at least one conformal weight made from metal and is able to be moved to another port, and wherein the at least one conformal weight is secured within the at least one shallow weight port by the protrusion.

2. The golf club head of claim 1, wherein the at least one conformal weight is composed of a high-density metal alloy.

3. The golf club head of claim 1, further comprising a damping layer, wherein the damping layer is disposed between the at least one shallow weight port and the at least one conformal weight.

4. The golf club head of claim 1, wherein the at least one conformal weight comprises a polymer having a specific gravity value of 1.8 to 4.2.

5. The golf club head of claim 1, wherein the lightweight material is a composite material, and wherein the base structure is composed of a metal alloy.

6. The golf club head of claim 5, wherein the metal alloy is a titanium alloy.

7. The golf club head of claim 5, wherein the striking face is integrally cast with the skeletal support structure.

8. The golf club head of claim 1, wherein the at least one of the crown and the sole is removably affixed to the skeletal support structure.

9. The golf club head of claim 1, wherein the at least one shallow weight port is integrally formed with the skeletal support structure.

10. The golf club head of claim 1, wherein the shallow recess is disposed at a rear portion of the sole.

11. The golf club head of claim 1, wherein the golf club head is a wood-type golf club head.

12. The golf club head of claim 1, wherein at least one of the crown and the sole is transparent.

13. The golf club head of claim 12, wherein each of the crown and the sole is transparent.

14. The golf club head of claim 1, wherein at least one of the crown and the sole is affixed to the body with an adhesive.
