  • DIMPLE PATTERNS FOR GOLF BALLS
    Publication number: 20200114212
    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.

  • GOLF BALL DIMPLE PROFILE
    Publication number: 20200061418
    Abstract: The present invention concerns a golf ball having dimples with a cross-sectional profile comprising a conical top portion and a 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. The dimples optionally have a transition surface connecting the conical top portion to the land area of the golf ball and/or a transition surface connecting the conical top portion to the bottom portion.

  • GOLF BALL
    Publication number: 20200061419
    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.

  • Golf ball having non-planar parting line
    Patent number: 10556153
    Abstract: The present invention is directed to a golf ball having a non-planar parting line on its spherical surface. The plurality of dimples located adjacent to the parting line consists of a first portion of dimples, each dimple of the first portion having a wave relief distance of from 0.001 inches and 0.005 inches, and a second portion of dimples, each dimple of the second portion having a wave relief distance of greater than 0.008 inches, where wave relief distance is measured as the shortest distance from the average dimple diameter of the dimple to the parting line.

  • Curvilinear golf ball dimples and methods of making same
    Patent number: 10532250
    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.
