Abstract

A golf ball with improved distance is disclosed. The golf ball has a relatively low spin velocity coupled with a particular dimple number, diameter, depth and arrangement. The ball is characterized by a lower flight trajectory and longer total distance. In a preferred embodiment (Example 10, shown in FIG. 2), the dimples marked 18 have a diameter of 0.140 inches±0.002 inches, while the balance of the dimples have a diameter of 0.160 inches±0.002 inches.

Claims

1. A golf ball having a surface with dimples arranged in a substantially icosahedron pattern thereon, said icosahedron pattern having a plurality of substantially equilateral triangles, each of said equilateral triangles having three side lines and a center area, said dimples being divided into two sets, each set of dimples having a different diameter, said dimples being arranged on said surface such that dimples selected from the first set of dimples are positioned on said three side lines of a plurality of said equilateral triangles and dimples selected from the secind set of dimples are positioned in said center area of a plurality of said equilateral triangles.

2. The golf ball of claim 1 wherein the dimple diameter of one set of dimples is 0.140 inch ±

0.002 inch and the dimple diameter of the other set of dimples is 0.160 inch ±

0.002 inch.

3. A golf ball having a surface with dimples arranged thereon, said surface divided into two hemispherical surfaces, one said hemispherical surface having dimples arranged thereon substantially similar to the other hemispherical surface, each said hemispherical surface having dimples arranged in a hemi-icosahedron pattern thereon, said hemi-icosahedron pattern having a plurality of substantially equilateral triangles, each of said equilateral triangles having three sides and a center area, said dimples consisting essentially of two sets of dimples, a first set of dimples having a small dimple diameter and a second set of dimples having a large dimple diameter as compared to said small dimple diameter, said dimples being arranged on the surface of said golf ball such that dimples selected from said first set are positioned on each of said three sides of each of said equilateral triangles and dimples selected from said second set are positioned in each of said center areas of each of said equilateral triangles.

4. The golf ball of claim 3 wherein the small dimple diameter is 0.140 inch ±

0.002 inch and the large dimple diameter is 0.160 inch ±

0.002 inch.

5. A golf ball having a surface with a plurality of dimples arranged thereon, said dimples consisting essentially of two sets of dimples, a first set of dimples having a small dimple diameter and a second set of dimples having a large dimple diameter as compared to said small dimple diameter, said dimples being arranged on said surface of said golf ball in a substantially icosahedron pattern composed of a plurality of quilateral triangles, each equilateral triangle of said icosahedron having three sides and a center area, said dimples being arranged on said surface such that dimples selected from said first set are arranged on each of said three sides of each of said equilateral triangles and dimples selected from said second set are arranged in said center area of each of said equilateral triangles.

6. The golf ball of claim 5 wherein the small dimple diameter is 0.140 inch±

0.002 inch and the large dimple diameter is 0.160 inch±

0.002 inch.

9. The golf ball of claim 5 wherein the dimple diameter of said second set of dimples is 0.160 inch±

0.002 inch and the dimple diameter of said one set of dimples is 0.140 inch ±

0.002 inch.

7. A golf ball having dimples on the surface thereof, said dimples being arranged on the two hemispherical surfaces of the ball, the dimples on one of said hemispherical surfaces being arranged substantially the same as the dimples on the other of said hemispherical surfaces, the dimples on each said hemispherical surface being of at least two sets, one of said sets of dimples having a larger dimple diameter than another of said sets of dimples, imaginary lines drawn through adjacent dimples of one said set of dimples forming a plurality of substantially spherical triangles on the surface of the ball, the spherical triangles being arranged substantially in the form of a part of an icosahedron on each hemispherical surface of the ball, the dimples of a second said set of dimples lying wholly within the said spherical triangles formed by the said imaginary lines.

8. The golf ball of claim 7 wherein the dimples of said second said set of dimples have a larger dimple diameter than the dimple diameter of the dimples of said one said set of dimples.
