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.
Claims20
A golf club head comprising:
- a crown;
- a sole;
- a toe;
- a heel;
- a faceplate comprising a lattice, the lattice comprises a plurality of land portions that form a plurality of flexure shape recesses;
- each flexure shape recess comprises:
- a major end nodule;
- a minor end nodule;
- and
- a narrowed portion connecting the major end nodule and the minor end nodule;
- wherein the major end nodule comprises a circular shape with a major diameter;
- wherein the minor end nodule comprises a circular shape with a minor diameter;
- wherein the major diameter is larger than the minor diameter;
- and
- wherein the plurality of flexure shape recesses are separate and not connected with each other.
