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 body;

an insert bonded to the body to at least partially define a hollow interior club head volume; and

an elongate weight removably received or selectively retained into a bore within the insert;

wherein, the elongate weight comprises a longitudinal axis and the elongate weight is asymmetrically balanced about the longitudinal axis;

the elongate weight further comprises one or more radial protrusions that extend outward from a body of the elongate weight; and

the one or more protrusions of the weight slide freely in a longitudinal direction down one or more channels of the bore.

2. The golf club head of claim 1, wherein,

the elongate weight is rotatable about its longitudinal axis from a first weight configuration to a second weight configuration.

3. The golf club head of claim 2, wherein,

the elongate weight further comprises a first indicia and a second indicia;

the first indicia represents the first weight configuration; and

the second indicia represents the second weight configuration.

4. The golf club head of claim 3, wherein,

the first indicia is hidden when the elongate weight is in the second weight configuration;

and

the second indicia is hidden when the elongate weight is in the first weight configuration.

5. The golf club head of claim 2, wherein rotation of the elongate weight results in alteration of the center of gravity of the club head.

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

7. The golf club head of claim 2, wherein the insert is transitioned between the first weight configuration and the second weight configuration under the assistance of a tool;

and the tool is configured to fit within a recess in an end of the weight and transmit a torque to the weight.

8. The golf club head of claim 2, wherein,

the elongate weight is further rotatable to a third configuration;

the first weight configuration is a locked configuration, which prevents the weight from being longitudinally removed from the bore of the insert;

the second weight configuration is a locked configuration, which prevents the weight from being longitudinally removed from the bore of the insert; and

the third configuration is an unlocked configuration, which allows the weight to be longitudinally removed from the bore of the insert.

9. The golf club head of claim 1, wherein:

the elongate member is insertable within the bore in either a first orientation or a second orientation;

in the first orientation a first end of the weight makes initial entry into the bore and is closer to the face than a second end of the weight; and

in the second orientation the second end of the weight makes initial entry into the bore and is closer to the face than a first end of the weight.

10. The golf club head of claim 9, wherein when the elongate member is switched from a first orientation to a second orientation, the center of gravity of the club head is shifted.

11. The golf club head of claim 10, wherein the insert is formed from a polymeric material.

12. The golf club head of claim 1, wherein,

the first weight configuration and the second weight configuration are positioned between about 90 degrees and about 180 degrees apart.

13. The golf club head of claim 2, wherein,

the insert further comprises a rotational locking feature comprising a first stop and a second stop that both extend radially inward from an outer portion of the bore;

the first stop and the second stop are configured to align with the rotational path of the one or more protrusions as the elongate weight is rotated between the first weight configuration and the second weight configuration.

14. The golf club head of claim 13, wherein,

the first stop and the second stop inhibit any rotational motion caused by a torque that is below a predetermined torque threshold;

and

the first stop and the second stop elastically yield under a torque load above the predetermined torque threshold and allow the one or more protrusions to pass.

15. The golf club head of claim 1, wherein,

the bore of the insert further comprises one or more channels and one or more cinching ramps;

and

the one or more protrusions contact the one or more cinching ramps, which exert a longitudinal force onto the one or more protrusions to draw the weight into the bore.

16. The golf club head of claim 1, further comprising a damping member disposed at an end of the bore that is opposite from an opening of the bore of the insert.

17. The golf club head of claim 16, wherein,

the damping member comprises a deformable material selected from the group consisting of a rubber and a thermoplastic polyurethane material.

18. The golf club head of claim 16, wherein,

the damping member firmly secures the elongate weight by placing an elastic biasing pressure on the elongate weight.

19. The golf club head of claim 18, wherein, the elongate weight compresses the damping member by about 15% to about 45% of an original thickness of the damping member.
