    摘要： An golf club head with a structure that improves the sound and reduces stress placed on the face upon impact with a golf ball is disclosed herein. In particular, the golf club head is an iron with a face having a rear protrusion, also referred to as a piston, with both forward and rearward facing surfaces. The piston is at least partially received within a receptacle provided in the body of the golf club head. The receptacle also includes a pair of bumpers, one of which interacts with the piston to improve the sound of the face upon impact with a golf ball at speeds at which an average golfer would swing the club head, and the other of which reduces the stress placed on the face when the club makes impact with a golf ball at high speeds.

    摘要： A golf club head comprising a body, a variable face thickness pattern, and a plurality of solid metal stiffening rods, and which satisfies the equation Vballnorm≥0.0356x+140.82, is disclosed herein. The body comprises a face, a sole, and a return section, and defines a hollow interior. Each of the rods extends from the return section to the sole within the hollow interior proximate the face to reduce stresses placed on the face during impact with a golf ball. The rods are all located within 1 inch of a rear surface of the face 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. The variable face thickness pattern preferably comprises a plurality of concentric rings, with a center ring having a thickness that is less than a thickness of an intermediary ring.

    摘要： A golf club head with a face stress-reduction structure disposed proximate a rear surface of a striking face is disclosed herein. In particular, the structure is an adjustable tension cable assembly extending from an upper portion of the golf club head, preferably a return section, to a lower portion of the golf club head, preferably a sole portion, approximately parallel with the rear surface of the striking face. The cable assembly comprises a cable portion, a hollow sleeve, and a screw plug.

    摘要： A golf club head comprising a body and a stiffening structure is disclosed herein. The body comprises a face section, a sole section, and a crown section, and defines a hollow interior. The stiffening structure extends within the hollow interior from the crown section to the sole section to reduce stresses placed on the face section during impact with a golf ball. The stiffening structure is entirely located within 0.500 inch of a rear surface of the face section measured along a plane normal to the center of the face, and within 1 inch of the center of the face section along a horizontal axis parallel to the face section, and comprises heel and toe connectors connected to one another by a middle connector, such that the stiffening structure has an approximately X- or H-overall shape.

    摘要： An iron-type golf club head comprising a body with a striking face and a hollow cavity portion, a medallion, and a damping insert that is spaced from, and does not contact any portion of, the striking face is disclosed herein. The damping insert is trapped between the medallion and a support structure that extends from the body of the club head approximately parallel with the striking face, and is at least partially suspended over or in the cavity portion. The structure may be an elongated stiffening member that connects upper and lower portions of the body to one another, or a rectangular lip section. The damping insert is affixed to only one of the medallion and the structure with an adhesive material, and damps vibration in the striking face after the striking face makes contact with a golf ball, while the striking face is rebounding from impact.
