  • 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.

  • 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.

  • Publication number: 20190232129
    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: 10173110
    Abstract: A golf club head comprising multiple means of adjusting the location of the center of gravity, and the bias, is disclosed herein. In a preferred embodiment, the golf club head comprises a non-metal medallion comprising a channel that is affixed to one of the crown and the sole, a slidable weight sized to fit within the channel, and a cover that attaches to the medallion and locks the slidable weight within the channel at a location selected by a user. The cover preferably includes at least one cutout so that the slidable weight is at least partially visible to the user when it is locked within the channel. The cover also includes additional cutouts that receive protrusions extending from the medallion to more securely attach the cover to the medallion.

  • Patent number: 9968834
    Abstract: A golf club head comprising a channel and a sliding weight that can be reversibly fixed at any point within the channel is disclosed herein. The channel preferably is disposed on the sole and extends from a heel side of the golf club head, around a rear side, and ends at a toe side of the golf club head. This channel is not constrained to a planar arc, but instead twists as it extends around the golf club head so that it follows the contours, and preserves the aesthetics, of the golf club head. The slidable weight comprises a base portion and a first cap, and a second cap that has the same dimensions as, and is interchangeable with, the first cap is disposed in a pocket in the sole proximate the face of the golf club head.
