  • Publication number: 20210236891
    Abstract: 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.

  • Patent number: 11045697
    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: 10532258
    Abstract: The present invention is directed to a body for a golf club head that includes structural columns or connectors, also referred to as stiffening members, and particularly a pair of solid rods, that extend between a return section and a sole section approximately parallel with a rear surface of a striking face section and parallel with each other without touching the rear surface or one another, even during impact with a golf ball. Each of the solid rods preferably is cylindrical, has a diameter of 0.050 inch to 0.200 inch, and has a length of 1 to 2.5 inches. Each of the rods has an upper end and a lower end. The solid rods preferably have a variable diameter to reduce their overall mass, such that the upper ends and lower ends have diameters that are larger than, and taper towards, a midpoint of the solid rods so that the solid rods each has an approximate hourglass shape.

  • 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.
