Publication number: 20190091529Abstract: A golf club head includes a club head body and a weight member that is secured to the body in a weight mount. The weight member is constructed to utilize lateral forces to couple to the head body to minimize the structure required to retain the weight member. The weight member includes a spring feature that is movably coupled to a weight body so that it is movable between a first configuration and a second configuration. In the second configuration a portion of the spring feature extends outward from a side wall of the weight body. The weight mount includes an undercut and the spring feature extends into the undercut and is partially flexed by the abutment of the spring feature and a perimeter wall of weight mount when the weight member is disposed in the weight mount.Type: ApplicationFiled: November 26, 2018Publication date: March 28, 2019Applicant: Acushnet CompanyInventors: Jonathan Hebreo, Andrew McCarthy, Noah de la Cruz, Grant M. Martens
