Publication number: 20230372779Abstract: A golf ball includes a generally spherical surface and a plurality of dimples separated by a land area. At least one of the dimples has a perimeter edge connected to the land area and a dimple surface surrounded by the perimeter edge. The dimple surface includes a plurality of channels and a plurality of channel edges that extend continuously from the perimeter edge to an intersection at a dimple center. The dimple surface defines a dimple point depth in relation to continuation of the land area and a channel point depth in relation to the channel edges. Each channel includes a first area having a plan shape of a circular sector of a channel circle. The channel edges extend radially from the dimple center to a terminal end at the channel circle. The perimeter edge intersects the channel circle only at terminal ends of the plurality of channel edges.Type: ApplicationFiled: May 18, 2022Publication date: November 23, 2023Applicant: Acushnet CompanyInventors: Michael R. Madson, David P. Hunt

Patent number: 10293213Abstract: The present invention is directed to a golf ball having a non-planar parting line about non-circular dimples on its spherical surface. The parting line comprises non-concentric arcs having straight connecting line segments between the arcs. Each arc maintains a tangency with its connecting lines and a relief distance greater than or equal to 0.003 inches when measured from an average non-circular dimple diameter to one of the non-concentric arcs and an absolute relief distance of at least 0.001 inches when measured from all points on the non-circular dimple perimeter to one of the non-concentric arcs. The sum of the lengths of the non-concentric arcs relates to the sum of the straight connecting line segments according to the equation: (0.15)?LARCS??LLINES?(0.50)?LARCS.Type: GrantFiled: April 24, 2018Date of Patent: May 21, 2019Assignee: Acushnet CompanyInventors: Michael R.

Patent number: 9649536Abstract: The present invention is directed to a golf ball comprising of non-concentric arcs defining a non-planar parting line on its spherical surface resulting in having a large size disparity between non-circular dimples in one hemisphere and adjacent non-circular dimples from the opposing hemisphere. The parting line is produced by a pair of adjacent non-circular dimples, wherein ?d indicates the average non-circular dimple diameter and N indicates dimples from the Northern hemisphere and those from the Southern hemisphere are indicated by S. A large disparity may be created, if the following condition is satisfied: ? d ? ( N ) ? d ? ( S ) > 1.25 ? ? or ? ? ? d ? ( N ) ? d ? ( S ) < 0.80 .Type: GrantFiled: November 2, 2015Date of Patent: May 16, 2017Assignee: Acushnet CompanyInventors: Nicholas M. Nardacci, Michael R. Madson, David P. Hunt
