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, a sole, and a channel in the sole; and
a slidable weight assembly comprising a retention plate, a weighted base, and at least one bolt having a head portion and a threaded extension portion,wherein the channel comprises a curved floor, a first wall, a second wall, a first rail extending from the first wall, and a second rail extending from the second wall,wherein the retention plate comprises a first lower surface, at least one first through-bore, and at least one ledge having a second lower surface that is offset from the first lower surface,wherein the weighted base comprises an upper surface, at least one threaded bore, and at least one convex spherical portion centered around the at least one threaded bore,wherein the at least one convex spherical portion has the same approximate curvature as the channel,wherein the head portion rests against the at least one ledge within the first through-bore when the bolt is engaged with the retention plate,wherein the threaded extension portion is sized to engage the at least one threaded bore,wherein the bolt reversibly fixes the slidable weight to the rails, andwherein the retention plate does not make contact with the weighted base when the slidable weight assembly is fixed within the channel.

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 an S-shaped channel disposed in its sole and a slidable weight assembly comprising a retention plate, at least one bolt, and a weighted base. The weighted base comprises at least one spherical portion extending from its underside to permit the slidable weight assembly to slide smoothly within the channel, which preferably has a partially tubular cross-section along a vertical Z-axis. The bolt, when tightened, reversibly fixes the slidable weight assembly to a pair of rails extending into the channel from the channel'"'"'s walls.

16. A weight assembly comprising:
-
a retention plate comprising a first lower surface, a first unthreaded through-bore, a second unthreaded through-bore, a first ledge extending beneath the first unthreaded through-bore, and a second ledge extending beneath the second unthreaded through-bore, each of the first and second ledges having a second lower surface that is vertically offset from the first lower surface; a weighted base comprising an upper surface, a first threaded bore, a second threaded bore, a first convex spherical portion centered around the first threaded bore, and a second convex spherical portion centered around the second threaded bore; and at least one bolt having a head portion and a threaded extension portion, wherein the head portion rests against one of the first and second ledges when the at least one bolt is engaged with the retention plate, wherein the threaded extension portion is sized to engage one of the first and second threaded bores, and wherein the weight assembly is approximately oval in shape. - View Dependent Claims (17, 18, 19, 20)
