  • Golf club head with adjustable hosel
    Patent number: 10596421
    Abstract: A golf club head having an adjustable hosel assembly and a plug assembly that can reversibly secure the hosel assembly in a chosen configuration within the club head is disclosed herein. In particular, the hosel assembly includes a shaft sleeve that is trapped within a hosel opening with a screw that extends through an interior flange. The plug assembly includes a wedge-shaped flange that is inserted into an opening in the body and fits between the interior flange and the head of the screw to temporarily immobilize the shaft sleeve. The plug assembly preferably completely fills the opening in the body so as to preserve a smooth outer mold line of the club head and allow graphics or decorations to extend across the exterior surface without disruption.

  • Golf club head having adjustable stress-reducing structures
    Patent number: 10589154
    Abstract: A golf club head comprising a body and a plurality of adjustable stiffening members is disclosed herein. The body comprises a face section, a sole section, and a crown section or a return section, and also defines a hollow interior. Each of the plurality of stiffening members is at least partially disposed within the hollow interior, and extends from the crown section or return section to the sole section to reduce stresses placed on the face during impact with a golf ball. The stiffening members, each of which comprises a rod and a tube, may be adjusted to be in compression or tension, thereby preloading the body and affecting the stresses experienced by the golf club head upon impact with a golf ball.

  • Golf club head with face damping and stress-reduction features
    Patent number: 10569146
    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.

  • Golf club head having stress-reducing features
    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.
