Abstract

A golf club head includes a club head body and a weight member that is secured to the body. The weight member is constructed to utilize lateral forces to couple to the head body to minimize the structure required to retain the weight member, and the weight member is preferably constructed so that it has a low profile.

Claims (34)

1. A golf club head including a weight member, comprising:

a club head body;

a weight mount disposed in a portion of the club head body, wherein the weight mount includes an aperture defined by an outer surface of the golf club head body and at least one spline tab, wherein the weight mount defines an undercut adjacent the aperture; and

a weight member comprising a weight body, a spring clip, and a locking mechanism, wherein the weight body includes a first flange that includes at least one spline tab, wherein the first flange is spaced from a second flange by a clip portion, wherein the weight body defines a bore that extends through the first flange and at least a portion of the clip portion, wherein the clip portion defines at least one aperture extending radially through the clip portion,

wherein the spring clip is disposed on the clip portion;

wherein the locking mechanism includes a locking member and at least one roller, wherein the at least one roller is disposed in the at least one aperture in the clip portion, and wherein the at least one roller abuts a cam surface of the locking member and an inner surface of the spring clip;

wherein the cam surface of the locking member has an outer dimension that is different at different locations around the locking member,

wherein the locking member is rotatably coupled to the weight body,

wherein in a first configuration of the weight member the locking member is oriented so that the at least one roller is aligned with a first portion of the cam surface and the spring clip forcibly abuts the at least one roller,

wherein in a second configuration of the weight member the locking member is oriented so that the at least one roller is aligned with a second portion of the cam surface and forcibly abuts the spring clip to force the spring clip outward and away from the clip portion of the weight body and into the undercut, and

wherein the spline tab of the first flange mechanically interlocks with the spline tab of the weight mount so that relative rotation between the weight body and the weight mount is prevented.

2. The golf club head of claim 1 , wherein the golf club head includes a plurality of weight mounts.

3. The golf club head of claim 1 , wherein the spring clip comprises a clip alignment feature that is a tab, wherein the weight body comprises a body alignment feature that is a slot in the second flange, and wherein the tab extends into the slot.

4. The golf club head of claim 1 , wherein the locking member includes a circumferential groove in an outer surface, wherein the weight body includes a circumferential groove in an inner surface formed by the bore, and wherein a snap ring extends into the circumferential groove of the locking member and the circumferential groove of the weight body so that the locking member is rotatably coupled to the weight body in the bore.

5. The golf club head of claim 1 , wherein the at least one roller is a ball.

6. The golf club head of claim 1 , wherein the spring clip is biased toward the center of the weight member.

7. The golf club head of claim 1 , wherein the first flange of the weight body is annular, wherein the second flange of the weight body is annular, and wherein the clip portion of the weight body is annular.

8. The golf club head of claim 1 , wherein the weight mount includes a tapered flange, and wherein the spring clip abuts the tapered flange when the weight member is in the second configuration.

9. The golf club head of claim 1 , wherein the weight member further comprises a gasket disposed on the first flange of the weight body, and wherein the gasket is disposed between the first flange and the weight mount when the weight member is located in the weight mount.

10. The golf club head of claim 1 , wherein the cam surface of the locking member includes at least one detent and at least one ramp, and wherein the locking member has a minimum outer dimension on the at least one detent and a maximum outer dimension on the at least one ramp.

11. A weight member for a golf club head, comprising:

a weight body including a first flange that includes at least one spline tab, wherein the first flange is spaced from a second flange by a clip portion, wherein the weight body defines a bore that extends through the first flange and at least a portion of the clip portion, and wherein the clip portion defines at least one aperture extending radially through the clip portion;

a spring clip disposed on the clip portion; and

a locking mechanism that includes a locking member and at least one roller, wherein the at least one roller is disposed in the at least one aperture in the clip portion, wherein the at least one roller abuts a cam surface of the locking member and an inner surface of the spring clip;

wherein the locking member is rotatably coupled to the weight body, wherein the cam surface of the locking member has an outer dimension that is different at different locations around the locking member,

wherein in a first configuration of the weight member the locking member is oriented so that the at least one roller abuts a first portion of the cam surface and the spring clip forcibly abuts the at least one roller, and

wherein in a second configuration of the weight member the locking member is oriented so that the at least one roller is aligned with a second portion of the cam surface and forcibly abuts the spring clip to force the spring clip outward and away from the clip portion of the weight body.

12. The weight member of claim 11 , wherein the spring clip comprises a clip alignment feature that is a tab, wherein the weight body comprises a body alignment feature that is a slot in the second flange, and wherein the tab extends into the slot.

13. The weight member of claim 11 , wherein the locking member includes a circumferential groove in an outer surface, wherein the weight body includes a circumferential groove in an inner surface formed by the bore, and wherein a snap ring extends into the circumferential groove of the locking member and the circumferential groove of the weight body so that the locking member is rotatably coupled to the weight body in the bore.

14. The weight member of claim 11 , wherein the at least one roller is a ball.

15. The weight member of claim 11 , wherein the spring clip is biased toward the center of the weight member.

16. The weight member of claim 11 , wherein the first flange of the weight body is annular, wherein the second flange of the weight body is annular, and wherein the clip portion of the weight body is annular.

17. The weight member of claim 11 , wherein the weight member further comprises a compressible gasket disposed on the first flange.

18. The weight member of claim 11 , wherein the cam surface of the locking member includes at least one detent and at least one ramp, and wherein the locking member has a minimum outer dimension on the at least one detent and a maximum outer dimension on the at least one ramp.
