Patent number: 10279230Abstract: Provided is a golf club head that is able to suppress lowering of the pitch of a ball hitting sound. The golf club head according to the present invention includes a crown portion, a face portion, and a sole portion having at least one recessed portion. The recessed portion is configured to house a weight member such that the weight member does not protrude externally. The sole portion is provided with a placement region connected to the face portion and to be at least partially placed on a placement surface in a reference state, and a rear region arranged further to a back side in a face-back direction than the placement region and in which the recessed portion is arranged. The rear region inclines upward relative to the placement region toward the back side.Type: GrantFiled: May 18, 2016Date of Patent: May 7, 2019Assignee: SUMITOMO RUBBER INDUSTRIES, LTD.Inventors: Hiroshi Abe, Naruhiro Mizutani, Daisuke Kohno

Patent number: 10245487Abstract: In general, aspects of this invention relate to golf clubs or golf club components incorporating adjustment members that permit ready adjustability of golf club parameters and/or interchangeability of golf club components to change a golf club configuration, and methods for providing golf clubs. According to aspects of this invention, an adjustment member may be utilized to allow the adjustability of a golf club parameter to change a golf club configuration, while ensuring there is substantially no change to other club or club head variables, parameters or characteristics. According to another aspect of this invention, an adjustment member may be utilized to allow the adjustability of two golf club parameters independently to change a golf club configuration, while ensuring there is substantially no change to other club or club head variables, parameters or characteristics.Type: GrantFiled: August 8, 2016Date of Patent: April 2, 2019Assignee: Karsten Manufacturing CorporationInventors: Robert Arluna, Robert Boyd, Hiroshi Kawaguchi, Eric A. Larson, Robert Lukasiewicz, Jr., George W. Moody, Jr., Andrew G. V. Oldknow, Raymond J. Sander, John T. Stites

Patent number: 10195497Abstract: An oversized golf club head and golf club having a large volume, large head dimensions, and/or large face characteristics, as well as unique mass property attributes driven by relationships not often considered in conforming club head design, to achieve a resistance to squaring the oversized club head during a golf swing that is comfortable to the novice golfer, a feel similar to a non-oversized golf club, stability during off-center impacts, and preferred launch characteristics. This is achieved in part via establishing a club head configuration and associated center of gravity location that results in a preferred magnitude of Delta1 and Delta2 values, CG angle, moments of inertia, and associated ratios, relationships, and club head mass property characteristics influenced by these variables, to account for the significant scale of the oversized club head and achieve improved performance.Type: GrantFiled: September 13, 2016Date of Patent: February 5, 2019Assignee: TAYLOR MADE GOLF COMPANY, INCInventors: Mark Vincent Greaney, John Francis Lorentzen, Matthew Greensmith, Craig Richard Slyfield

Patent number: 10105580Abstract: A set 2 includes two or more iron type golf clubs 4 having loft angles different from each other. Each club 4 includes a shaft sf, a head hd, and a grip gp. The head hd includes a top surface 10, a sole surface 12, and a face surface 14 having a face line gv. The sole surface 12 includes a leading edge E1 and a trailing edge E2. In a planar view of the sole surface 12, the trailing edge E2 is curved so as to project toward a face side. A sole width WSc at a middle position of the face line gv is increased as the loft angle is increased.Type: GrantFiled: March 10, 2017Date of Patent: October 23, 2018Assignee: SUMITOMO RUBBER INDUSTRIES, LTD.Inventors: Yuki Shimahara, Daisuke Kohno

Patent number: 10039963Abstract: A golf club head includes a striking face having a face center and a virtual striking face plane generally parallel to the striking face. The golf club head further includes a sole portion, a top portion, a rear portion, and a loft L no less than 40°. A virtual vertical plane perpendicular to the striking face plane passes through the face center. A club head center of gravity is spaced from the virtual vertical plane in the heel-to-toe direction by a distance D1 that is no greater than 6.0 mm. The golf club head further includes a hosel including an internal bore configured to receive a golf shaft. The internal bore includes a peripheral side wall and a shaft abutment surface configured to abut a tip end of the golf club shaft. The hosel further comprises an auxiliary recess extending sole-ward from the abutment surface of the internal bore.Type: GrantFiled: November 3, 2016Date of Patent: August 7, 2018Assignee: Dunlop Sports Co., Ltd.Inventors: Patrick Ripp, Brian Herr, Mika Becktor, Keith Dolezel

Patent number: 9999811Abstract: 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 has a thickened portion including an annular tapered area that tapers in thickness between an upper boundary and a lower boundary and encloses an elevated area bounded by the upper boundary. The upper and/or lower boundary defines a shape having two lobes, each with an outer edge with a convex profile, and a connecting portion extending between the lobes, such that the connecting portion is defined by two outer edges extending between the outer edges of the lobes, wherein at least one of the outer edges of the connecting portion has a concave outer profile.Type: GrantFiled: September 26, 2014Date of Patent: June 19, 2018Assignee: Karsten Manufacturing CorporationInventors: Robert M. Boyd, Jeremy N. Snyder, Hiroshi Kawaguchi, James S. Thomas, Raymond J. Sander, Rick S. Wahlin, Akira Shimozuma

Patent number: 9962584Abstract: A golf club head comprises a body having a face, a crown and a sole together defining an interior cavity. The body having a channel located on the sole and extending generally from a heel end of the body to a toe end of the body. A weight member movably positioned within the channel such that a position of the weight member within the channel is able to be adjusted, thereby adjusting a location of a center of gravity of the body. Additionally, adjustment of the weight member provides a maximum x-axis adjustment range of the position of the center of gravity (Max ?CGx) that is greater than 2 mm and a maximum z-axis adjustment range of the center of gravity (Max ?CGz) that is less than 2 mm.Type: GrantFiled: December 13, 2016Date of Patent: May 8, 2018Assignee: Taylor Made Golf Company, Inc.Inventors: Joseph Reeve Nielson, Nathan T.
