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.
Claims20
A golf club head including a weight member, comprising:
- a club head body comprising a plurality of body members that combine to define a hollow body, wherein the body members include a face defining a ball-striking surface, a sole, a crown, and a skirt, wherein the sole extends aftward from a lower edge of the face, wherein the crown extends aftward from an upper edge of the face, and wherein the skirt extends between the sole and the crown around a perimeter of the body;
- a weight mount disposed on at least one of the body members, wherein the weight mount includes an aperture defined by an outer surface of the golf club head body, 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 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 a plurality of apertures 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 a plurality of rollers, wherein each of the plurality of rollers is disposed in one of the plurality of apertures in the clip portion, and wherein each of the rollers abuts a cam surface of the locking member and an inner surface of the spring clip;
- wherein the cam surface of the locking member includes a plurality of detents and a plurality of ramps, wherein the cam surface of the locking member has an outer dimension that is different at different locations around the locking member from a minimum distance at a detent to a maximum dimension on a ramp,
- wherein the locking member is rotatably coupled to the weight body,
- wherein the spring clip is biased toward the center of the weight member, wherein in a first configuration of the weight member the lock member is oriented so that the plurality of rollers are aligned with the plurality of detents and the spring clip forcibly abuts the rollers, and
- wherein in a second configuration of the weight member the lock member is oriented so that the rollers forcibly abut the spring clip to force the spring clip outward and away from the clip portion of the weight body and into the undercut.

A weight member for a golf club head, comprising:
- a weight body including a first flange that 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 a plurality of apertures extending radially through the clip portion;
- a spring clip disposed on the clip portion;
- and
- a locking mechanism, wherein the locking mechanism includes a locking member and a plurality of rollers, wherein each of the plurality of rollers is disposed in one of the plurality of apertures in the clip portion, and wherein each of the rollers abuts a cam surface of the locking member and an inner surface of the spring clip;
- wherein the cam surface of the locking member includes a plurality of detents and a plurality of ramps, 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 from a minimum distance at a detent to a maximum dimension on a ramp, wherein the spring clip is biased toward the center of the weight member,
- wherein in a first configuration of the weight member the lock member is oriented so that the plurality of rollers are aligned with the plurality of detents and the spring clip forcibly abuts the rollers into the detents, and wherein in a second configuration of the weight member the lock member is oriented so that the rollers forcibly abut the spring clip to force the spring clip outward and away from the clip portion of the weight body.

- and
- a weight member comprising a weight body, a spring clip, and a locking mechanism,
- wherein the weight body defines a bore;
- wherein the weight body defines a plurality of apertures extending radially from the bore;
- wherein the spring clip is surrounds at least a portion of the weight body;
- wherein the locking mechanism includes a locking member and a plurality of rollers, wherein each of the plurality of rollers is disposed in one of the plurality of apertures, and wherein each of the rollers abuts a cam surface of the locking member and an inner surface of the spring clip;
- wherein the cam surface of the locking member includes a plurality ramps, 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 the spring clip is biased toward the center of the weight member, wherein in a first configuration of the weight member the lock member is oriented so that the plurality of rollers are aligned with a low point of the plurality of ramps, and
- wherein in a second configuration of the weight member the lock member is oriented so that the rollers forcibly abut the spring clip to force the spring clip outward and away from the clip portion of the weight body, preventing the weight member from dislodging from the weight mount.
