Abstract

A golf club head having a face component, a crown, and a composite sole with one or more weight ports for receiving one or more weight inserts is disclosed herein. At least part of each of the weight ports is integrally formed in the composite sole, and each of the weight ports include a weight receiving region for receiving a weight and a screw receiving region for receiving a screw that secures the weight in the weight port.

Claims

1. A golf club head comprising:

a face plate;

a crown;

a composite sole comprising an interior surface, an exterior surface, and at least one integrally formed weight port;

at least one metal screw-receiving component comprising a first bore; and

at least one removable weight sized to fit within and make direct contact with the at least one integrally formed weight port,

wherein the first bore comprises threads,

wherein the golf club head has a volume of at least 120 and no more than 600 cubic centimeters,

wherein the weight port comprises a first diameter and a second bore having a second diameter,

wherein the first diameter is greater than the second diameter, and

wherein the screw-receiving component is affixed to the weight port with an adhesive such that the first bore aligns with the second bore.

2. The golf club head of claim 1, wherein the sole comprises a heel section and a toe section, and wherein the at least one integrally formed weight port is disposed in the toe section.

3. The golf club head of claim 2, wherein the sole further comprises a second, integrally formed weight port, and wherein the second weight port is located in the heel section.

4. The golf club head of claim 1, wherein the screw-receiving component is affixed to the interior surface of the sole.

5. The golf club head of claim 1, wherein the screw-receiving component is affixed to the exterior surface of the sole.

6. The golf club head of claim 1, wherein the weight is affixed to the weight port with a metal screw.

7. The golf club head of claim 1, wherein the weight is composed of a metal material and has a weight of no less than 2 grams and no more than 20 grams.

8. The golf club head of claim 1, wherein the weight is composed of both metal and non-metal materials.

9. The golf club head of claim 1, wherein the crown is composed of a composite material.

10. The golf club head of claim 9, wherein the crown comprises at least one integrally formed weight port.

11. The golf club head of claim 9, wherein the crown and sole are integrally formed.

12. A golf club head comprising:

a face plate composed of a titanium alloy;

a crown comprising a first integrally formed weight port;

a composite sole comprising a second integrally formed weight port and a third integrally formed weight port;

a first metal screw-receiving component comprising a first bore;

a second metal screw-receiving component comprising a second bore; and

a plurality of removable weights sized to fit within and make direct contact with at least one of the integrally formed weight ports,

wherein each of the first and second bores comprises threads,

wherein the golf club head has a volume of at least 120 cubic centimeters and no more than 600 cubic centimeters,

wherein each of the second and third integrally formed weight ports comprises a first diameter and an unthreaded bore having a second diameter,

wherein the first diameter is greater than the second diameter,

wherein the first screw-receiving component is affixed to the second integrally formed weight port with an adhesive such that the first bore aligns with the unthreaded bore, and

wherein the second screw-receiving component is affixed to the third integrally formed weight port with an adhesive such that the second bore aligns with the unthreaded bore.

13. The golf club head of claim 12, wherein the crown is composed of a metal material.

14. A driver-type golf club head comprising:

a metal face plate;

a composite aft body comprising a crown, a ribbon, and a sole;

at least two metal screw-receiving components, each of which comprises a threaded bore; and

at least one removable metal weight,

wherein the aft body comprises at least two, integrally formed weight ports;

wherein each of the integrally formed weight ports comprises a first diameter and an unthreaded bore comprising a second diameter,

wherein the first diameter is greater than the second diameter,

wherein each of the at least two metal screw-receiving components is affixed to one of the integrally formed weight ports such that the threaded bore aligns with the unthreaded bore,

wherein the at least one weight is affixed within one of the at least two weight ports such that the at least one weight makes direct contact with the weight port, and

wherein the driver-type golf club head has a volume of no less than 440 cubic centimeters and no more than 470 cubic centimeters.

15. The driver-type golf club head of claim 14, wherein the face plate is composed of a titanium alloy.
