Publication number: 20240075358Abstract: A golf club head, preferably a putter head, comprising at least one structural support member is disclosed herein. The structural support member has a smooth, organic-looking aesthetic, with a continuously changing curvature along its spline and at least one surface, and preferably connects one portion of the golf club head to another portion. Where the support member connects to other portions of the golf club head, the surfaces of the member have a curvature that changes smoothly and continuously, lacking any sharp corners. The support member may be part of a lattice structure formed via binder jetting.Type: ApplicationFiled: November 7, 2023Publication date: March 7, 2024Applicant: Topgolf Callaway Brands Corp.Inventors: Eric Stubben, William C. Watson, Brandon D. DeMille, David R. Handy, Irina Ivanova, Patrick Dawson

Patent number: 11878221Abstract: Methods of creating golf club components with complex structures that would be difficult, impossible, or cost prohibitive to produce, such as lattice structures, beam structures, and complex surface-based structures, are described herein. In particular, a binder jet machine is used create complex structures to optimize weighting, sound, and performance of golf club heads. The method preferably includes the steps of designing a golf club head component in CAD using optimization software, printing the component from a powdered material, and then removing excess powder from the component via port holes that extend into an external surface of the component and communicate with interior voids within the component.Type: GrantFiled: May 21, 2021Date of Patent: January 23, 2024Assignee: Topgolf Callaway Brands Corp.Inventors: Brandon D. DeMille, Eric Stubben, David R. Handy, Irina Ivanova, Patrick Dawson
