Golf Club Head With Adjustable Center of Gravity
First Claim
1. A golf club head comprising:
- a body comprising a crown, a sole, a heel side, a toe side, a face portion, a rear side, an edge portion where the crown connects with the sole, and a channel; and
a weight comprising a base comprising a threaded bore, a cap comprising a through-bore, and a bolt,wherein the cap comprises a first sidewall protrusion and a second sidewall protrusion,wherein the channel comprises a first wall, a second wall, a floor, a first rail extending from the first wall, and a second rail extending from the second wall,wherein the weight is disposed within and movable to any location in the channel,wherein the base and the cap sandwich a portion of each of the first and second rails,wherein tightening the bolt reversibly fixes the weight to the rails, andwherein moving the weight within the channel changes both a moment of inertia and a location of a center of gravity of the golf club head.

Abstract
A golf club head comprising a channel and a sliding weight that can be reversibly fixed at any point within the channel is disclosed herein. The channel preferably is disposed on the sole and extends from a heel side of the golf club head, around a rear side, and ends at a toe side of the golf club head. This channel is not constrained to a planar arc, but instead twists as it extends around the golf club head so that it follows the contours, and preserves the aesthetics, of the golf club head. The slidable weight comprises a base portion and a first cap, and a second cap that has the same dimensions as, and is interchangeable with, the first cap is disposed in a pocket in the sole proximate the face of the golf club head.

13. A driver-type golf club head comprising:
-
a body comprising a crown, a sole, a heel side, a toe side, a face portion, a rear side, an edge portion where the crown connects with the sole, and a channel; and a weight comprising a base comprising a threaded bore, a cap comprising a through-bore, and a bolt, wherein the cap comprises a lower cavity, wherein the base is sized to fit within the lower cavity, wherein the bolt connects the base to the cap, wherein the base and the cap do not make direct contact with one another, wherein the channel comprises a first wall, a second wall, a floor, a first rail extending from the first wall, and a second rail extending from the second wall, wherein the weight is disposed within and movable to any location in the channel, wherein the base and the cap sandwich a portion of each of the first and second rails, wherein tightening the bolt reversibly fixes the weight to the rails, and wherein moving the weight within the channel changes both a moment of inertia and a location of a center of gravity of the golf club head. - View Dependent Claims (14, 15)

16. A golf club head comprising:
-
a composite crown; a metal body comprising a sole, a heel side, a toe side, a face portion, a rear side, and a channel; an edge portion where the composite crown connects with the metal body; and a weight comprising a base comprising a threaded bore, a cap comprising a through-bore, and a bolt, wherein the cap comprises a lower cavity, wherein the base is sized to fit within the lower cavity, wherein the bolt connects the base to the cap, wherein the base and the cap do not make direct contact with one another, wherein the channel comprises a first wall, a second wall, a floor, a first rail extending from the first wall, and a second rail extending from the second wall, wherein the weight is disposed within and movable to a plurality of locations in the channel, wherein the base and the cap sandwich a portion of each of the first and second rails, wherein tightening the bolt reversibly fixes the weight to the rails, and wherein a distance between the edge portion and a midpoint of the channel remains constant for at least 50% of the length of the channel. - View Dependent Claims (17, 18, 19, 20)
