GOLF CLUB HEAD WITH ADJUSTABLE CENTER OF GRAVITY
First Claim
1. A golf club head comprising:
- a body comprising a hosel, a striking face, a heel side, a toe side, a rear side, and a sole;
a rail comprising a stem and a ledge extending approximately perpendicular to, and away from, the stem; and
a slidable weight assembly comprising a weight body and a rotatable portion,wherein the weight body comprises an upper portion, a base portion extending from and perpendicular to the upper portion, and at least one rounded nub extending from and approximately perpendicular to the base portion,wherein the rotatable portion comprises a cylindrical body and a curved protrusion extending from a lower end of the cylindrical body,wherein the curved protrusion extends only partially around the cylindrical body,wherein the upper portion comprises an opening sized to receive an upper end of the cylindrical body,wherein the upper end of the cylindrical body is permanently trapped within the opening,wherein the stem extends from, and is approximately perpendicular to, the sole,wherein the ledge is spaced from the floor, andwherein rotating the rotatable portion causes at least a portion of the curved protrusion to slide under the ledge and reversibly fixes the slidable weight assembly to the rail.

Abstract
A golf club head comprising a slidable weight for adjusting the location of the club head center of gravity is disclosed herein. The club head has a channel disposed in its sole and a slidable weight assembly comprising a weight body and a rotatable cam portion. The channel includes a single, L-shaped rail extending upwards from a channel floor, and the slidable weight assembly is reversibly fixed to the rail when the rotatable cam portion is rotated such that a curved protrusion is disposed underneath a ledge of the L-shaped rail. The channel preferably has an S-shaped or closed loop configuration such that the club head'"'"'s center of gravity can be adjusted along X (front to back) and Y (heel to toe) horizontal axes.
