Abstract

A golf ball having two hemispheres separated by an equator. Each hemisphere has an identical dimple pattern comprising a dimple-free area adjacent the equator, a plurality of substantially identical sections extending between the pole and the equator with each dimple pattern comprising a plurality of elongated dimples, each dimple having an axis extending at an angle relative to the equator between 0° and 90° in either direction. The majority of the dimples overlap at least one adjacent dimple.

Claims

1. A spherical golf ball having a plurality of dimples formed on the spherical surface thereof, said surface defining a pole in each hemisphere thereof and an equator midway between said poles dividing the surface into two hemispheres, each of said hemispheres having substantially the same dimple pattern, said dimple pattern in each hemisphere comprising

a dimple-free area adjacent said equator;

a plurality of substantially identical sections extending between a pole and said equator, each of said sections having a dimple pattern comprising

a plurality of elongated dimples, each of said dimples having an elongated axis extending at any angle relative to said equator from 0°

to 90°

in either direction; and

the majority of said dimples overlapping at least one adjacent dimple.

2. The golf ball of claim 1 further comprising a dimple-free area surrounding the pole in each hemisphere.

3. The golf ball of claim 1 wherein all of said dimples overlap.

4. The golf ball of claim 1 wherein each of said dimples has its longitudinal axis extending from said equator toward said pole.
