Patent number: 8657701Abstract: A ball striking device, such as a golf club head, has a head that includes a face configured for striking a ball and a body connected to the face, the body being adapted for connection of a shaft proximate a heel thereof. The face includes one or more stiffening members or other structures on the inner surface of the face to provide locally increased stiffness to particular areas of the face. Certain stiffening members may provide greater stiffness than other stiffening members, allowing the face to be configured for areas of greatest stiffness and greatest COR tailored to common impact patterns.Type: GrantFiled: July 13, 2012Date of Patent: February 25, 2014Assignee: Nike, Inc.Inventors: Robert Boyd, John T. Stites

Patent number: 8655631Abstract: The accuracy or computation speed of mechanical analysis of a golf ball using the finite element method is increased. In the mechanical analysis, a model representing the golf ball is prepared on a computer, and computation is made by the finite element method using elements and nodes. At this time, the elements are made solid elements of hexahedron, the aspect ratio of the shape of each element is set so as to be not lower than 1.0 and not substantially higher than 6.5, and nodes are provided on the sides and at the vertexes of the hexahedron of element.Type: GrantFiled: November 7, 2012Date of Patent: February 18, 2014Assignee: Bridgestone Sports Co., Ltd.Inventors: Takuichi Shimizu, Hideo Matsunaga

Patent number: 8647217Abstract: A hollow golf club head comprises a main body member provided with a face opening and a sole opening, a face member brazed/soldered to the main body member to close the face opening, and a sole member brazes/soldered/welded to the main body member to close the sole opening. The main body member has a thin front edge part of the sole opening and a thick heat blocking part between the thin front edge part and the face portion. The sole member has a front edge part connected to the sole opening's front edge part and a thicker sole reinforcing part positioned backward thereof. The thicknesses of the sole member's front edge part and the sole opening's front edge part are not less than 0.5 mm and less than 2.5 mm. The thicknesses of the sole reinforcing part and the heat blocking part are 2.5 to 10.0 mm.Type: GrantFiled: May 25, 2012Date of Patent: February 11, 2014Assignee: SRI Sports LimitedInventor: Masayoshi Nishio

Patent number: 8641555Abstract: A ball striking device, such as a golf club, includes a head with a face having an outer surface configured for striking a ball, a body connected to the face, and a channel located in the body. The channel is configured to influence the characteristics of the impact of a ball on the face, such as by flexing or compressing in response to the force of the impact, exerting a response or reaction force on the face, changing the motion or behavior of the face, and other manners. The head may also include a pair of channels that have a gap between them.Type: GrantFiled: August 6, 2012Date of Patent: February 4, 2014Assignee: Nike, Inc.Inventors: John T. Stites, Robert Boyd, Rick Wahlin, Andrew G. V. Oldknow
