  • Patent number: 10413789
    Abstract: 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.

  • Patent number: 10406407
    Abstract: A golf club head having elevated internal weighting that improves ball speed, reduces backspin, and increases launch angle is disclosed herein. In particular, the golf club head comprises a hollow body with a face, sole, and elevated weight bar, which is disposed inside the body and is fixed to heel and toe sides of the body, preferably with mechanical fasteners such as screws or bolts. The weight bar bridges a central portion of the sole, and a central section of the weight bar, which preferably comprises at least 50% of the overall mass of the weight bar, extends towards the face without actually making contact with the face. The sole also includes at least one slot extending perpendicular to the face and underneath the central section of the weight bar, the slot having a front-to-back length that is greater than a maximum front-to-back length of the weight bar.

  • Patent number: 10406408
    Abstract: 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.
