Abstract

A golf ball is provided with evenly and uniformly distributed dimples. The spherical surface of the golf ball is divided into thirty-two geometric shapes, comprising twelve spherical pentagons and twenty spherical hexagons. The arrangement of the dimples on the spherical surface is generally defined by the sides of the spherical pentagons and hexagons. The uniform distribution of dimples is such that the golf ball displays multiple axes of symmetry.

Claims

1. A golf ball having a spherical surface with a plurality of dimples formed therein, said dimples being arranged by dividing said spherical surface into twelve identical spherical pentagons and twenty identical identical spherical hexagons.

2. The golf ball according to claim 1 wherein:

all of said dimples are formed within the boundaries of said spherical pentagons and hexagons so that said dimples do not intersect the sides of any of said spherical squares and hexagons.

3. The golf ball according to claim 1 wherein:

at least one of said dimples intersects at least one side of at least one of said spherical pentagons or hexagons.

4. The golf ball according to claim 1 wherein:

all of said dimples are of the same approximate size and configuration.

5. The golf ball according to claim 1 wherein:

said dimples are of varying sizes.

6. A golf ball having a spherical surface with a plurality of dimples formed therein, the arrangement of said dimples being defined by the projection of a geometric prism onto said spherical surface of said golf ball, said geometric prism comprising twelve pentagons and twenty hexagons.
