  • Patent number: 11161018
    Abstract: A face insert for a golf club head, preferably a putter head, is disclosed herein. The face insert comprises a pair of stacked plates, each with a plurality of hinge features. The hinge features of the lower plate extend through openings in the upper plate so that the plates are locked together, and the edge surfaces of the hinge features combine to create a striking surface that increases topspin of a golf ball.
    Type: Grant
    Filed: January 14, 2021
    Date of Patent: November 2, 2021
    Assignee: Callaway Golf Company

  • Patent number: 10821333
    Abstract: A resilient face insert for a golf club head, preferably a putter head, is disclosed herein. In particular, the face insert comprises a plurality of hinge features spaced from a striking surface to ensure consistent ball speed across the striking surface. Each hinge feature comprises a tab portion that is spaced from the striking surface by a stem portion and that extends parallel to the striking surface, and is angled with respect to a horizontal y-axis. The orientation of hinge features with respect to the y-axis varies across the face, which reduces sidespin from mishits and produces consistent topspin regardless of impact location of a golf ball on the face insert.
