Dimple patterns for golf balls
First Claim
1. A golf ball having a plurality of dimples covering at least 78% of the spherical outer surface thereof, wherein the dimples are arranged in a pattern defined by a hexagonal dipyramid projected on the spherical outer surface of the ball, the pattern consisting of twelve substantially identical dimple sections, wherein each of the twelve dimple sections comprises at least three different dimple diameters and at least two different chord depths, wherein the largest dimple diameter ratio among nearest neighbor dimples on the ball is 1.4 or less, wherein there are no dimple free great circles on the outer surface of the ball;
- wherein the border of each of the dimple sections consists of two linear side edges and a non-linear base edge;
wherein each dimple section consists of a plurality of shared non-polar dimples each of which has a centroid that lies along a side edge of the section, a plurality of dimples that are not intersected by a side edge, and, optionally, a shared polar dimple having a centroid that lies at the vertex of the two linear side edges of the section;
wherein the dimples within each dimple section that are located adjacent to the base edge of the section include dimples having at least three dimple diameters that differ by at least 0.005 inches.
