Patent number: 11752399Abstract: A golf club head with hosel reinforcement structures arrayed around a hosel axis and extending from an inner mold line of the golf club head within a reinforcement region is disclosed herein. The reinforcement structures include ribs and scallops, which are arranged in specific positions within the reinforcement region to maximize hosel bendability without sacrificing the structural integrity of the golf club head.Type: GrantFiled: July 27, 2022Date of Patent: September 12, 2023Assignee: Topgolf Callaway Brands Corp.Inventors: Yaming Pan, Nathan Reed, Denver Holt, James A.

Publication number: 20230256467Abstract: Methods of applying a polymeric coating to a rear face surface of golf club heads with variable face thickness are disclosed herein. The coating, which preferably comprises polyurea, improves the durability of the face and reduces the hits to failure ratio of the golf club head. The coating improves the performance of the golf club head because it allows for reduction in overall face thickness and easy post-process manipulation to allow for fine-tuning of mass properties after production. The reduction in thickness leads to overall weight reduction, because the polymer is roughly a quarter of the density of titanium or stainless steel, and also reinforces the face, thereby increasing the lifespan of the club.Type: ApplicationFiled: March 31, 2023Publication date: August 17, 2023Applicant: Topgolf Callaway Brands Corp.Inventors: Nathan Samuel Reed, Denver Holt

Publication number: 20230049575Abstract: A golf club head comprising a body and a hollow stiffening structure is disclosed herein. The body comprises a face section, a sole section, and a crown section, and defines a hollow interior. The hollow stiffening structure extends within the hollow interior from the crown section to the sole section to reduce stresses placed on the face section during impact with a golf ball. The hollow stiffening structure creates stiffness in a vertical, crown-sole direction of the body, while reducing stiffness in the horizontal, front-rear direction, and is filled with a weighted dampening insert that extends the entirety of the length of the stiffening structure and blocks entry into the stiffening structure.Type: ApplicationFiled: May 16, 2022Publication date: February 16, 2023Inventors: Nathan Reed, James A. Seluga, Denver Holt, David Handy

The body comprises a face section, a sole section, and a crown section, and defines a hollow interior. The hollow stiffening structure extends within the hollow interior from the crown section to the sole section to reduce stresses placed on the face section during impact with a golf ball. The hollow stiffening structure creates stiffness in a vertical, crown-sole direction of the body, while reducing stiffness in the horizontal, front-rear direction. These two effects combine to increase ball speed and improve other performance metrics from low center through high center ball impact locations, and simultaneously lower CT of the golf club.Type: ApplicationFiled: September 14, 2021Publication date: February 16, 2023Inventors: Nathan Reed, James A.

Patent number: 11364423Abstract: A golf club head comprising a body and a stiffening structure is disclosed herein. The body comprises a face section, a sole section, and a crown section, and defines a hollow interior. The stiffening structure extends within the hollow interior from the crown section to the sole section to reduce stresses placed on the face section during impact with a golf ball. The stiffening structure is entirely located within 0.500 inch of a rear surface of the face section measured along a plane normal to the center of the face, and within 1 inch of the center of the face section along a horizontal axis parallel to the face section, and comprises heel and toe connectors connected to one another by a middle connector, such that the stiffening structure has an approximately X- or H-overall shape.Type: GrantFiled: April 20, 2021Date of Patent: June 21, 2022Assignee: Callaway Golf CompanyInventors: Christopher A. G. Nunez, James A. Seluga, Matthew Myers, Denver Holt, Evan D. Gibbs

Patent number: 11325013Abstract: A golf club head comprising a body and a plurality of stiffening members, the tension or compression of which can be adjusted, is disclosed herein. The body comprises a face section, a sole section, and a crown section or a return section, and also defines a hollow interior. Each of the plurality of stiffening members is at least partially disposed within the hollow interior, and extends from the crown section or return section to the sole section to reduce stresses placed on the face during impact with a golf ball. The compression or tension of the stiffening members may be adjusted to affect the stresses experienced by the golf club head upon impact with a golf ball.Type: GrantFiled: January 6, 2021Date of Patent: May 10, 2022Assignee: Callaway Golf CompanyInventors: Jeremy R. Hanhart, Michael Hallack, Homer G. Aguinaldo, James A. Seluga, Christopher A. G. Nunez, Matthew Myers, Denver Holt

Patent number: 11045697Abstract: An golf club head with a structure that improves the sound and reduces stress placed on the face upon impact with a golf ball is disclosed herein. In particular, the golf club head is an iron with a face having a rear protrusion, also referred to as a piston, with both forward and rearward facing surfaces. The piston is at least partially received within a receptacle provided in the body of the golf club head. The receptacle also includes a pair of bumpers, one of which interacts with the piston to improve the sound of the face upon impact with a golf ball at speeds at which an average golfer would swing the club head, and the other of which reduces the stress placed on the face when the club makes impact with a golf ball at high speeds.Type: GrantFiled: August 10, 2020Date of Patent: June 29, 2021Assignee: Callaway Golf CompanyInventors: James A.
