Abstract: A golf club head with means for adjusting a center of gravity along more than one axis is disclosed herein. The golf club head comprises at least one rectangular weight bar disposed within a recessed region on the sole and adjustable within the recessed region. One end of the weight bar is reversibly fixed to the sole with a connection element, while the other end includes an engagement feature that engages a retention feature at the edge of the recessed region. The retention feature provides multiple locations at the edge of the recessed region to which the engagement feature can be fixed, and when the weight bar is in a configuration desired by a golfer, the weight bar can be reversibly secured to the sole and immobilized within the recessed region by tightening the connection element. The weight bar may also include a slidable weight assembly.

Abstract: A golf club head comprising a means for adjusting the location of the center of gravity is disclosed herein. In particular, the golf club head of the present invention comprises two channels, each having at least one shoulder portion, a floor, and a rail extending upwards from the floor. The channels intersect at a junction, and a slidable weight comprising a top portion, a mechanical fastener, and a clamping structure is disposed within at least one of the channels. When the mechanical fastener is tightened, the top portion presses against the at least one shoulder portion and pulls the clamping structure upward so that the clamping structure grips the rail. The rails are spaced from one another at the junction, and the clamping structure allows the slidable weight to be moved into either of the channels without being indexed.

Abstract: A golf club head comprising a body, at least one weight cartridge, and a plurality of hollow tubes is disclosed herein. The body comprises a face section, a sole section, and a return section, and also defines a hollow interior. Each of the plurality of hollow tubes extends from the return section to the sole section to reduce stresses placed on the face during impact with a golf ball, and the at least one weight cartridge is sized to fit within at least one of the plurality of hollow tubes. The sole section and return section each comprise keyed apertures providing access to the hollow tubes with which they communicate, and the at least one weight cartridge comprises a keyed structure sized to fit through the keyed apertures.

Abstract: A golf club head having multiple structural columns is disclosed herein. A body comprises a face section, a sole section, and a crown or return section, and defines a hollow interior.

The structural columns are all located within 1 inch of a rear surface of the face section measured along a plane normal to the center of the face, and are spaced a distance of 0.500 to 2.00 inch from one another within the hollow interior.

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.

Abstract: A golf club head comprising at least one weight port and a cam weight sized to reversibly lock into the weight port is disclosed herein. The weight port includes a floor, a wall, a first seating tab extending from the wall, and a second seating tab extending from the wall, but no openings communicating with an interior of the golf club head. The cam weight, which preferably is composed of a single material, includes a cylindrical body, a first helical wing, a second helical wing, and a tool engagement feature. The helical wings give the cam weight a keyed shape, which matches the shape of the weight port when the seating tabs are taken into account.

Abstract: A golf club head comprising a body and a plurality of stiffening members and satisfying the equation Vballnorm?0.0356x+140.82 is disclosed herein. The body comprises a face section, a sole section, and a crown or return section, and defines a hollow interior. Each of the plurality of stiffening members extends from the crown or return section to the sole section within the hollow interior to reduce stresses placed on the face section during impact with a golf ball. The stiffening members are all located within 1 inch of a rear surface of the face section measured along a plane normal to the center of the face, and are spaced a distance of 0.500 to 2.00 inch from one another within the hollow interior.
