Patent Images
1. A golf club head comprising:
- a faceplate comprising a lattice, the lattice comprises a plurality of grooves arranged in a sunburst pattern,each sunburst groove comprises;
a base groove; and
a plurality of ligament grooves, the plurality of ligament grooves connected to the base groove and extending outward from the base groove;
wherein the base groove comprises a circular shape;
wherein the ligament groove comprises at least one curve; and
wherein at least three sunburst grooves form a flexure shape, the flexure shape comprises a portion of at least three base grooves and at least three ligament grooves to form a series of convex and concave curves relative to a center of the flexure shape; and
wherein the series of convex and concave curves of the flexure shape flex during golf ball impacts to store energy through linear and torsional bending.

Abstract
Embodiments of golf club head faceplates comprising a lattice to improve the energy storage capabilities and minimize stress concentrations are described herein. The lattice can comprise a plurality of flexure shapes that facilitate in faceplate bending. The flexure shapes of the lattice can comprise a reentrant, concave, or non-convex shape. The lattice can comprise at least one repeating pattern of flexure shapes that can be interconnected or spaced apart. During golf ball impacts, the flexure shapes flex to store energy through linear and torsional bending.
