Patent number: 11857848Abstract: A golf club head includes a body, a solid portion, and a lattice structure. The body includes a topline, a sole, and an internal cavity arranged between the topline and the sole. The solid portion is arranged within the internal cavity and is fabricated from a solid material. The lattice structure is arranged within the internal cavity and is formed layer by layer via an additive manufacturing process. The lattice structure defines a lattice volume and the solid portion defines a solid volume. An orientation of the lattice structure between the topline and the sole and a volume ratio between the lattice volume and the solid volume define a location of a center of gravity defined by the body.Type: GrantFiled: April 17, 2020Date of Patent: January 2, 2024Assignee: Cobra Golf IncorporatedInventors: Ryan L.

Patent number: 11618213Abstract: A process of manufacturing a golf club head includes the steps of generating, via an additive manufacturing process, a golf club head. Generating, via an additive manufacturing process, the golf club head includes the steps of printing a first material, layer by layer, along a first plane, and creating a first blow through aperture that allows air to pass from a front portion of the golf club head to a head cavity disposed within a rear portion of the golf club head. The process further includes blowing excess material out from within the head cavity using the first blow through aperture, and removing excess material formed at one or more material deposits disposed along the golf club head.Type: GrantFiled: April 17, 2020Date of Patent: April 4, 2023Assignee: Cobra Golf IncorporatedInventors: Ryan L. Roach, Cameron J. Day, Bryce W. Hobbs

Patent number: 11524213Abstract: A golf club head includes a body and an insert. The body defines a top side, a toe side, and a heel side, and includes a sole extending between the toe side and the heel side at a location on the body opposite to the top side. The body defines an internal volume defined between a ball-striking face and an internal wall. The insert is arranged within the internal volume and is formed layer by layer via an additive manufacturing process. The insert includes a lattice structure arranged between a rear surface of the ball-striking face and the internal wall. The lattice structure is in engagement with the rear surface and formed integrally with the ball-striking face and the internal wall.Type: GrantFiled: July 20, 2020Date of Patent: December 13, 2022Assignee: Cobra Golf IncorporatedInventors: Ryan L. Roach, Cameron J. Day, Bryce W. Hobbs, D. Clayton Evans

Patent number: 11511166Abstract: Summary A golf club face member is made by a manufacturing process, such as 3D printing, for a complex topology that is sturdy with good CT. 3D printing creates a face in which struts, a lattice-like structure, a waffle-iron pattern, or interior voids provide great strength and low mass. A golf club head has a club head body defining a heel portion and a toe portion and a hosel extending upward from the heel portion when the club head is at address. A face member is disposed between the heel portion and the toe portion such that it faces forward when the club head is at address. At least portion of the face member comprises a 3D printed material such as a 3D printed or sintered metal.Type: GrantFiled: May 26, 2020Date of Patent: November 29, 2022Assignee: Cobra Golf IncorporatedInventors: Ryan L. Roach, Cameron J. Day, D. Clayton Evans, Steven M. Mitzel

Patent number: 11285365Abstract: The invention provides golf clubs and methods of making golf clubs with machined perimeter faces. The club faces provide an accurate ball striking surface and improved aerodynamics. In particular, a surface is milled into the club face that expands over an edge of a ball striking surface and onto a portion of the face adjacent to at least one of a crown, a sole, a toe, or a heel. During a swing, the milled surface causes the boundary layer of airflow to separate at a point closer to the rear of the club head, resulting in reduced drag.Type: GrantFiled: September 22, 2020Date of Patent: March 29, 2022Assignee: COBRA GOLF INCORPORATEDInventors: D. Clayton Evans, Cameron J. Day, Michael T. McDonnell, Ryan L. Roach, Douglas E. Roberts, Bryce Hobbs, Yi-ching Liao

Patent number: 10850169Abstract: 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.Type: GrantFiled: April 12, 2019Date of Patent: December 1, 2020Assignee: COBRA GOLF INCORPORATEDInventors: Cameron J. Day, D. Clayton Evans, Steven M. Mitzel

Patent number: 10821337Abstract: A golf club head includes a heel, a toe, a sole, and a rail. The toe is opposite the heel. The sole is between the toe and the heel. The sole has a forward portion and an aft portion. A forward-aft direction is defined from the forward portion to the aft portion. A heel-toe direction is defined from the heel to the toe. The rail extends outwardly from the sole along the forward-aft direction. The rail and the sole define an open-ended first channel extending along the rail in the forward-aft direction.
