  • Patent number: 10758784
    Abstract: Golf ball comprising dimple(s) incorporating three or more linear channels having the same channel length L and same channel width CW; all linear channels extend radially outward from a centroid of the dimple toward a perimeter of the dimple without intersecting the dimple's centroid. Each linear channel may extend radially outward from a location on the dimple that is a distance Cd from the dimple's centroid, wherein Cd>0. Alternatively, at least one of the three or more linear channels has a different channel length L and/or a different channel width CW than at least one other linear channel. Dimple may have circular or non-circular plan shape; channels may not intersect each other; at least one linear channel may intersect the dimple's perimeter; and linear channels may be spaced by n separation angles ?S, wherein n is number of linear channels, which may be equal, or at least two differ.

  • Patent number: 10758782
    Abstract: The present invention provides a method for arranging dimples on a golf ball surface in which the dimples are arranged in a pattern derived from at least one irregular domain generated from a regular or non-regular polyhedron. The method includes choosing control points of a polyhedron, generating an irregular domain based on those control points, packing the irregular domain with dimples, and tessellating the irregular domain to cover the surface of the golf ball. The control points include the center of a polyhedral face, a vertex of the polyhedron, a midpoint or other point on an edge of the polyhedron and others. The method ensures that the symmetry of the underlying polyhedron is preserved while minimizing or eliminating great circles due to parting lines.

  • Patent number: 10716970
    Abstract: The present invention provides a golf ball having an aerodynamic subsurface for packing dimples. More particularly, the invention relates to a golf ball having an exterior surface and at least a first subsurface containing at least two dimples located solely on the subsurface and lying below the exterior surface of the golf ball. A transition zone between the exterior surface and the subsurface is disclosed having an angle of transition and a top radius and a bottom radius. According to the present invention, the exterior surface and at least the first subsurface have at least a first and second surface colors that are different.

  • Patent number: 10709936
    Abstract: Golf balls including at least one modified dimple group are disclosed. The modified dimple group comprises one or more modified dimples forming an axially symmetric pattern about a Correction Area Centroid located on an axis of symmetry at a latitude greater than 0°, where 0° represents the hemispherical pole and 90° represents the equator. The modified dimples can be altered, for example, by changing dimple coverage, dimple diameter, dimple depth, dimple edge angle, dimple volume, dimple cross-sectional shape, and/or dimple plan shape. Optionally, the dimples have a catenary cross-sectional shape and the modified dimples are altered by changing the shape factor and/or chord depth. Such modifications preferably produce a golf ball that flies more consistently regardless of orientation when struck than a corresponding golf ball without such modifications.

  • Publication number: 20200215395
    Abstract: The present invention generally relates to golf balls having an internal skeletal structure that can be self-supporting. The golf ball preferably contains a spherical hollow inner core that is gas or liquid-filled. The ball further comprises an outer shell skeletal structure having a spherical shape and containing apertures that form hollow compartments. In one version, the skeletal structure supports itself and the space inside and around the skeletal structure is hollow. In another embodiment, the space is solid, for example, it may be foam-filled. In yet another version, the hollow space is filled with liquid. Multi-piece golf balls having outer cores, inner covers, and intermediate layers can be made.
