Patent number: 10238930Abstract: A golf club head includes a striking face, a sole portion, a top portion, a hosel, a rear surface, a loft no less than 40°, a virtual vertical plane, and a center of gravity. The striking face has a face center, a leading edge, and a virtual striking face plane. The hosel includes an internal bore configured to receive a golf shaft and includes a peripheral side wall and a shaft abutment surface configured to abut a tip end of the golf shaft. The rear surface is opposite the striking face and has an upper portion and a lower portion, the lower portion including a forward-extending recess. The insert covers the recess forming a hollow portion. The virtual vertical plane is perpendicular to the striking face plane and passes through the face center. The center of gravity is spaced a distance from the virtual vertical plane in the heel-to-toe direction.Type: GrantFiled: July 10, 2017Date of Patent: March 26, 2019Assignee: DUNLOP SPORTS CO.

Publication number: 20180311538Abstract: A method of customizing a golf club, wherein the method includes generating operating data representative of a user operating a mechanical device. The operating data is generated by a first sensor sized and configured to be removably positioned in a mounting port formed on the mechanical device during operation of the mechanical device. The sensor is interchangeably positionable in the mounting port with at least one mass insert, the at least one mass insert being adapted to be interchangeably positioned in the mounting to provide at least two different mass configurations. The method further includes determining a recommended configuration of the at least one mass insert specific to the user based on the operating data generated by the sensor, and transmitting information representative of the recommended mass insert.Type: ApplicationFiled: June 29, 2018Publication date: November 1, 2018Applicant: DUNLOP SPORTS CO.

Publication number: 20180021636Abstract: A sporting apparatus includes a monitoring device. The monitoring device may add no weight to the sporting apparatus relative to a comparable sporting apparatus without the monitoring device. The monitoring device may have a center of gravity substantially aligning with the center of gravity of the sporting apparatus, resulting in a sporting apparatus with a monitor having substantially the same center of gravity as a comparable sporting apparatus without a monitor. The sporting apparatus monitor may be configured to trim unreliable post impact swing data and replace it with extrapolated pre-impact swing data and/or more reliable post impact swing data.Type: ApplicationFiled: August 8, 2017Publication date: January 25, 2018Inventors: Keith Dolezel, Scott Carlyle, Michael J.
