Golf club head with openwork rib
First Claim
Patent Images
1. A golf club head comprising:
- a ball-striking face;
a crown and a sole extending back from the ball-striking face and cooperating to define an enclosed hollow body;
a hosel extending upwards from a heel side of the hollow body when the club head is at address; and
a first separately-constructed 3D printed support member comprising an openwork structure defining a Voronoi pattern disposed within the hollow body, wherein the first 3D printed support member defines an extended ridge with at least a first side and a second side and the openwork structure includes a plurality of apertures through the first side and the second side, wherein the first 3D printed support member is fastened at least partially to an interior surface of the sole and is positioned at, and configured to reinforce, a location of the club head identified, via finite element analysis, to exhibit strain in response to stress associated with impact between the ball-striking face and a golf ball;
a second 3D printed support member comprising an openwork structure defining a Voronoi pattern disposed within the hollow body, wherein the second 3D printed support member defines a buttress extending between an inside surface of the hosel and an inside surface of the sole; and
an adjustment mechanism comprising one or more attachment points for removable features for adjusting a feature of the club head.

Abstract
The invention provides a golf club head with an openwork (e.g., lattice-like or trellis-like) internal structural element that provides strength and stiffening at key points of the club head and/or attenuates sound while adding little to the overall mass due to the defined or irregular patterns of holes, piercings, gaps, or apertures through surfaces of the material. A golf club head may be given an openwork internal rib that reinforces regions of high strain, thereby minimizing material fatigue and preventing early breakage of the club head.
