Golf club with faceplate having variable thickness and contour
A recently granted patent (Publication Number: US11771962B2) describes a new design for a golf club. The golf club includes a head with a body and a faceplate that is integrally formed as a single unitary piece. The faceplate has a unique cross-section through a central location, with a continuously variable wall thickness that undergoes a non-constant rate of change of slope from an edge of the inner surface to an opposite edge of the inner surface through the central location.
The faceplate of the golf club is designed with multiple closed non-convex contour curves, each defined by a different constant faceplate wall thickness. These contour curves enclose each other, with each contour curve having a faceplate wall thickness difference of at least 0.2 mm. The patent also mentions the inclusion of additional closed non-convex contour curves with varying wall thickness differences.
The central location of the faceplate is highlighted as having the greatest characteristic time compared to other locations on the faceplate. The patent also specifies that the faceplate should not have any area of constant wall thickness greater than 1 mm2.
The cross-section of the faceplate can be horizontal, vertical, or at an angle of 30° or 60° with respect to the ground plane. In some embodiments, the faceplate may have polygonal shapes within the closed non-convex contour curves.
Importantly, the faceplate is devoid of any inwardly extending projection that defines a closed curve enclosing the central location.
The patent also describes the inclusion of annular regions within the faceplate, defined by inner and outer circles with specific radii. These annular regions should not include any convex contour curves.
Overall, this granted patent introduces a unique design for a golf club faceplate with continuously variable wall thickness and closed non-convex contour curves. The design aims to optimize the performance of the golf club by providing a faceplate with specific characteristics at the central location.
