Abstract: A golf club head includes a club body and a resting face angle adjuster. The club body includes a crown opposite a sole, a toe end opposite a heel end, a back end opposite a face, and a hosel. The sole includes a sole surface. The resting face angle adjuster includes an adjustment member having a keel surface, and a recess formed in the sole such that a portion of the sole surface at least partially bounds the recess. The adjustment member is disposed in the recess and positionable between a first adjustment position and a second adjustment position. In the first adjustment position, the keel surface is at a first distance relative to the portion of the sole surface. In the second adjustment position, the keel surface is at a second distance relative to the portion of the sole surface not equal to the first distance in the direction.

Abstract: A shim or badge is affixed to a golf club body to produce a cap-back iron, giving the appearance of a hollow-body iron. In this way, the golf club can be manufactured with the performance benefits of a game improvement iron, while providing the appearance of a blade, player's iron, and/or a hollow-body iron. For example, by using a lightweight and rigid shim or badge to close a cavity opening and extend into the toe portion in the golf club body, the golf club head can provide increased stiffness in the topline, while lowering CG. Various shim or badge arrangements and materials can be used, and a filler material and/or damper can be included within the cavity to improve sound and feel, while minimizing loss in COR.

Abstract: A golf club head with an improved sole profile is disclosed herein. More specifically, the present invention discloses various types of irons, including wedges, having a toe portion, a heel portion, and a center portion therebetween, in which a camber radius of a sole as measured from a front to a back of the golf club head changes moving from the toe portion through the center portion to the heel portion. In addition, a bounce angle of the golf club head also changes moving from the toe portion through the center portion to the heel portion. The resulting golf club head improves performance, as this new sole profile allows specific portions of the sole to have a profile that meets the needs at that location.

Abstract: A golf club head is formed by joining various parts to a head shell made of metal and having a hollow structure. The head shell has a region where a face and a sole are continuous with each other, thereby forming a leading edge between the face and the sole. The sole of the head shell is provided with a concave slot along the leading edge. The slot is configured to bend in a target direction upon hitting a ball with the face. A reinforcing member made of fiber reinforced plastic configured to apply a resistance to bending of the slot is attached in the slot. The slot has a thickness of, for example, about 0.8 mm to 1.3 mm and has a cross-sectional shape forming a parabola. The reinforcing member has a thickness of, for example, about 10% to 20% of the width of the slot in the target direction.

Abstract: A golf club head includes a face portion including a striking face for hitting a ball, a back face opposite the striking face, and a head outer peripheral surface extending between the striking face and the back face. The back face includes a cavity recessed on a striking face side and a frame portion extending along the head outer peripheral surface so as to surround the cavity. The frame portion is provided with at least one recess that extends along the striking face and opens to the head outer peripheral surface.

Abstract: The present invention relates to a golf club head having an adjustable weight assembly. More specifically, the adjustable weight assembly utilizes a weight member that's secured via a fastener along various positions within an elongate channel.

Abstract: A damper is provided within the cavity of a golf club head and spans substantially the full length of the striking face from heel-to-toe of the golf club head. One or more cutouts and/or other relief is provided in the damper to reduce the surface area of the damper that contacts the rear surface of the striking face. By reducing the surface area that the damper contacts the rear surface of the striking face, the full length damper improves the sound and feel of the golf club head at impact and only minimally reduces performance of the golf club head. For example, the one or more cutouts and/or other relief maintains face flexibility, characteristic time (CT) and coefficient of restitution (COR) of the striking face.

Abstract: A golf club head with a channel sized to receive one or more adjustable weights and an external support structure that bridges, and thereby supports, the channel without unduly interfering with weight adjustment is disclosed herein. The support structure, which includes one or more stiffening members on the exterior of the golf club head, improves the sound quality of the golf club head, and is particularly useful to attenuate the lower frequency mode shapes associated with slider channel geometry in golf club heads.
