Patent number: 8771104Abstract: The invention provides a golf ball having, on a surface thereof, a plurality of circular dimples, a plurality of non-circular dimples, and a land area which is a non-dimple region composed of a plurality of arcuate first lands, each formed along an edge of one of the circular dimples, and a plurality of second lands, each arranged so as to bridge between two neighboring circular dimples and having a shape that is recessed at a center portion thereof. The non-circular dimples have an edge shape defined by a plurality of the first lands in combination with a plurality of the second lands. In this golf ball, by fashioning the lands on the ball surface into a unique shape, the surface area of the lands is minimized and the dimple surface coverage is made even larger, increasing the aerodynamic performance and thus enabling the ball to travel even farther.Type: GrantFiled: May 24, 2011Date of Patent: July 8, 2014Assignee: Bridgestone Sports Co., Ltd.Inventors: Katsunori Sato, Takuma Nakagawa
