Abstract

A golf club head includes a first portion that is rigidly adhered to a second portion to at least partially define an interior club head volume. The first portion is formed from a metallic material and includes a face, and the second portion is formed from a polymeric material and defines a bore that is configured to receive and to selectively retain an elongate weight.

Claims

1. A golf club head comprising:

a first portion rigidly adhered to a second portion to at least partially define an interior club head volume;

wherein the first portion is formed from a metallic material and includes a face; and

wherein the second portion is formed from a polymeric material and includes;

a wall defining a bore that is configured to receive and to selectively retain an elongate weight; and

a stiffening feature integrally molded with the wall such that the stiffening feature extends outward from the bore.

2. The golf club head of claim 1, wherein the second portion includes a locking means for selectively retaining the elongate weight within the bore.

3. The golf club head of claim 1, wherein the stiffening feature is adhered to the first portion.

4. The golf club head of claim 1, wherein the polymeric material is a filled or unfilled thermoplastic polyamide.

5. The golf club head of claim 1, wherein the bore has a longitudinal axis;

and

wherein the longitudinal axis of the bore intersects the face.

6. The golf club head of claim 1, wherein the first portion is rigidly adhered to the second portion across a lap joint disposed therebetween.

7. A golf club head comprising:

a first portion rigidly adhered to a second portion to at least partially define an interior club head volume;

wherein the first portion is formed from a metallic material and includes a face;

wherein the second portion is formed from a polymeric material and includes;

a wall defining a bore that is isolated from the interior club head volume;

a means for selectively retaining a removable weight within the bore; and

a stiffening feature integrally molded with the wall such that the stiffening feature extends outward from the bore.

8. The golf club head of claim 7, wherein the polymeric material is a filled or unfilled thermoplastic polyamide.

9. The golf club head of claim 7, wherein the stiffening feature is adhered to the first portion.

10. The golf club head of claim 7, wherein the bore has a longitudinal axis;

and

wherein the longitudinal axis of the bore intersects the face.

11. The golf club head of claim 7, further comprising a means for translating a center of gravity of the club head between a first location and a second location, wherein the first location and the second location are disposed along an axis that intersects the face.

12. The golf club head of claim 7, wherein the first portion is rigidly adhered to the second portion across a lap joint disposed therebetween.

13. A golf club head comprising:

a first portion rigidly adhered to a second portion to at least partially define an interior club head volume; and

an elongate weight removably affixed to the second portion, the weight having a first end, a second end that is opposite the first end, and wherein each of the first end and the second end are disposed along a longitudinal axis of the elongate weight;

wherein the first portion is formed from a metallic material and includes a face; and

wherein the second portion is formed from a polymeric material and defines a bore that is configured to receive and to selectively retain the elongate weight; and

wherein the weight is insertable into the bore in either a first orientation or a second orientation such that the first end of the weight makes initial entry into the bore when inserted in the first orientation, and the second end of the weight makes initial entry into the bore when inserted in the second orientation.

14. The golf club head of claim 13, wherein the second portion includes a means for selectively retaining the elongate weight within the bore.

15. The golf club head of claim 14, wherein the second portion includes:

a wall defining the bore; and

a stiffening feature integrally molded with the wall such that the stiffening feature extends outward from the bore.

16. The golf club head of claim 15, wherein the stiffening feature is adhered to the first portion.
