Dimple patterns for golf balls
First Claim
1. A golf ball surface including two hemispheres each having a pole, wherein to two hemispheres are divided by an equator positioned midway between the poles, wherein the surface comprises:
- a dimple positioned at each pole; and
six substantially similar mating dimple sections located on each hemisphere,wherein each dimple section has a dimple pattern comprising dimples selectively positioned such that at least a portion of nearest neighbor dimples have diameter ratios of about 1.5 or greater, and wherein the nearest neighbor dimples comprising a diameter ratio of about 1.5 or greater are selectively positioned around an area of each dimple section located midway between the equator and the pole of each of the two hemispheres and not near the equator.

Abstract
A golf ball dimple pattern based on a hexagonal dipyramid polyhedron is disclosed. Preferably, the dimple pattern disclosed by the present invention includes dimples that are arranged such that at least a portion of neighboring dimples have one or more predetermined diameter ratios. The dimples are arranged based on six substantially similar mating dimple sections on each hemisphere. Each of the six substantially similar mating dimple sections on each hemisphere share a dimple positioned at the pole of that hemisphere. The dimple pattern is capable of achieving a surface coverage of about 82% or greater.
