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.
Claims19
A golf club head comprising:
- a faceplate comprising a lattice, the lattice comprises a plurality of land portions that form a plurality of flexure shape recesses;
- wherein:
- each land portion of the plurality of land portions is interconnected and defines portions of the faceplate devoid of the plurality of flexure shape recesses;
- each flexure shape recess of the plurality of flexure shape recesses comprises at least four vertices defining an acute interior angle, and a first vertex defining a first reflex angle;
- and
- the first reflex angle does not define an acute interior angle;
- and each flexure shape recess of the plurality of flexure shape recesses defines a depth from 0.025 inch to 0.075 inch.
