  • Patent number: 9925420
    Abstract: The present invention is a golf ball which comprises dimples having a cross section defined by the superposition of two or more continuous and differentiable functions, and particularly the superposition of a spherical curve and a cosine curve.

  • Patent number: 9925419
    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: 9908004
    Abstract: The present invention is directed to golf balls having improved aerodynamic performance due, at least in part, to the selection of the plan shapes of the dimples thereon. In particular, the present invention is directed to a golf ball that includes at least a portion of its dimples having a plan shape defined by low frequency periodic functions along a closed simple path. In addition, the present invention provides methods for designing dimples having a plan shape defined by a low frequency periodic function along a closed simple path.

  • Publication number: 20180043216
    Abstract: Golf balls having an initial velocity greater than 255 ft/sec and/or an overall distance of greater than 320 yards are disclosed. The golf balls comprise one or more core layers, one or more cover layers, and optionally one or more intermediate layers disposed between the core and the cover. At least one layer is optionally formed from a composition comprising from 2 wt % to 50 wt % of a plasticizer, based on the total weight of the composition.

  • Publication number: 20180036595
    Abstract: The present invention concerns a golf ball having dimples with a cross-sectional profile comprising a conical top portion and a non-conical bottom portion. More particularly, the profiles of the present invention are defined by three independent parameters: dimple diameter (DD), edge angle (?EDGE), and saucer ratio (Sr). These parameters fully define the dimple shape and allow for greater flexibility in constructing a dimple profile versus conventional spherical dimples. Further, conical dimples provide a unique dimple cross-section which is visually distinct.

  • Publication number: 20180036598
    Abstract: The present invention is directed to golf balls having surface textures with unique appearances and improved aerodynamic characteristics due, at least in part, to the use of curvilinear dimple plan shapes. In particular, the present invention is directed to a golf ball that includes at least a portion of its dimples having a plan shape defined by a number of convex or concave arcs that are derived from the vertices of a regular n-sided polygon, for example, an equilateral triangle or square.

  • Publication number: 20180036597
    Abstract: The present invention relates to golf balls having improved packing efficiency and aerodynamic characteristics and a high degree of dimple interdigitation. In particular, the present invention relates to a golf ball including at least a portion of dimples having a plan shape defined by low frequency periodic functions having high amplitudes. The present invention is also directed to methods of developing the dimple plan shape geometries, as well as methods of making the finished golf balls with the inventive dimple patterns applied thereto.

  • Patent number: 9878212
    Abstract: The present invention is directed to golf balls having improved aesthetics and desirable aerodynamic properties due, at least in part, to the novel shape of the dimples on the surface thereof. In particular, the present invention is directed to a golf ball that includes at least a portion of its dimples having a shape obtained from the intersection of a toroid and a sphere. The resulting curve of intersection represents the dimple perimeter and the intersecting portion of the surface of the toroid represents the dimple surface shape.
