Filed:

May 16, 2022

Appl. No.:

17/745591

Inventors:

- Carlsbad CA, US
James A. Seluga - Carlsbad CA, US
Denver Holt - Carlsbad CA, US
David Handy - Carlsbad CA, US

International Classification:

A63B 53/04

Abstract:

A golf club head comprising a body and a hollow stiffening structure is disclosed herein. The body comprises a face section, a sole section, and a crown section, and defines a hollow interior. The hollow 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 hollow stiffening structure creates stiffness in a vertical, crown-sole direction of the body, while reducing stiffness in the horizontal, front-rear direction, and is filled with a weighted dampening insert that extends the entirety of the length of the stiffening structure and blocks entry into the stiffening structure.

Patrick Dawson - San Diego CA, US

International Classification:

A63B 53/04
A63B 53/00

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.

International Classification:

A63B 53/04
A63B 53/00

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.
