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 balls having dimple patterns arranged in dipyramid layouts are disclosed. The patterns may be arranged in triangular dipyramid, quadrilateral dipyramid, pentagonal dipyramid, or hexagonal dipyramid layouts. The dipyramid patterns have six, eight, ten, or twelve substantially identical dimple sections, where each dimple section is defined by a spherical triangle. The dimples in each of the identical dimple sections have at least two different dimple diameters including a minimum dimple diameter and a maximum dimple diameter. The resulting dimple patterns have a surface coverage of about 70 percent or less. The reduced surface coverage helps to reduce the flight of the golf balls.

A golf ball includes a core, a cover and a coating layer disposed entirely about an outer surface of the cover. The coating layer is opaque about an entirety of the outer surface of the cover and consists of three regions: a first color region, a second color region, and a transition color region disposed between the first color region and the second color region about an entire circumference of the golf ball. The first color region consists of a spray-painted first color. The second color region consists of a spray-painted second color that is different than the spray-painted first color. The transition color region consists of a combination of the spray-painted first color and the spray-painted second color, wherein said combination produces a transitional color that is a spectrophotometer-measurable different color than both the first and the second colors.

A multi-piece solid golf ball having a two-layer core with an inner core layer and an outer core layer and having a cover of one or more layer with numerous dimples on the surface is characterized in that the hardest cover layer has a specific material hardness and the ball has a specific value obtained by subtracting the surface hardness of the overall core from the surface hardness of the hardest cover layer, a specific deflection, and a specific value obtained by subtracting the initial velocity of the inner core layer from the initial velocity of the sphere consisting of the inner core layer encased by the outer core layer. This golf ball enables relatively low head speed golfers to achieve a good distance on full shots with drivers and iron clubs and also provides a soft, comfortable feel at impact.

A golf swing training device for training a user to aim a golf swing in the desired direction includes a resiliently deformable body having a top surface, a bottom surface, and a perimeter surface extending between the top surface and the bottom surface. The bottom surface is configured to support the body on a support surface, and the body is elongated along a horizontal central longitudinal axis from a first end to a second end. The body is symmetrical about a vertical central plane. There is a divot penetrating the top surface adjacent the first end coupled to a compactable, resiliently deformable ball. The body is constructed of a low-density material and is configured to abruptly decelerate when moving through a quantity of air due to an air resistance force.

The present invention relates to golf balls, specifically to a golf ball comprising an aerodynamic pattern having novel shaped dimple structures which reduce the variation in airflow turning angle thereby improving the golf ball's flight performance. The dimple structures have a conical shaped base with a dimple in the center and reduced or no flat land areas between the dimples.

A golf ball with an aerodynamic design is disclosed herein. The aerodynamic design has a protrusion at a center of a hex geometry representing an increase in ball radius greater than 0.0005 inches from a minimum ball radius. The minimum ball radius is located between 0.01 and 0.04 inch (11%-46%) from the center of the hex geometry.

A golf ball 2 includes a core 4, a mid layer 6, a cover 8, and dimples 10. A Shore C hardness Hmc of the mid layer 6 is greater than a Shore C hardness Hs at a surface of the core 4. A Shore D hardness He of the cover 8 is less than a Shore D hardness Hm of the mid layer 6. Peak values and orders of maximum peaks of data constellations of the golf ball 2 are calculated. A minimum value of the peak values is not less than 95 mm. A minimum value of the orders is not less than 27, and a maximum value of the orders is not greater than 37. An average of the orders is not less than 30 and not greater than 34.
