Abstract

A golf ball having dimples covering its surface and having six great circular paths on the surface of the golf ball where none of the paths intersect a dimple is disclosed. The six great circular paths are obtained by inscribing a cubical pattern in the surface of the golf ball, dividing each square face of the cube into four isosceles triangles by bisecting the square face twice and filling each triangle so produced with dimples. A total of twenty-four triangles are obtained on the surface of the golf ball. Golf balls having six great circles and having 360, 384, 408, and 432 dimples are disclosed.

Claims

1. A golf ball having a spherical surface with a plurality of dimples formed thereon and six parting lines which do not intersect any dimple, the dimples being arranged by dividing the spherical surface into twenty-four spherical isosceles triangles, said twenty-four isosceles triangles being formed by inscribing a cube in said spherical surface and bisecting each face of said cube into four isosceles triangles, said six parting lines corresponding to six great circular paths formed along the bisecting lines of each square face of the cube, said dimples being arranged so that the dimples do not intersect the bisecting lines which form the six circular paths.

2. The golf ball of claim 1 wherein each isosceles triangle has a substantially similar dimple pattern.

3. The golf ball of claim 1 wherein the dimples are of two different sizes.

4. The golf ball of claim 1 wherein each isosceles triangle has the same number of dimples.

5. The golf ball of claim 1 wherein the total number of dimples is 360.

6. The golf ball of claim 1 wherein the total number of dimples is 384.

7. The golf ball of claim 1 wherein the total number of dimples is 408.

8. The golf ball of claim 1 wherein the total number of dimples is 432.

9. The golf ball of claim 1 wherein the total number of dimples is 384 and said dimples are triangular in shape.

10. A golf ball having a spherical surface with a plurality of dimples thereon and six great circular paths which do not intersect any dimples, the circular paths being arranged on the spherical surface by inscribing a cube in the spherical surface and bisecting each square face of said cube twice to form four isosceles triangles, said great circular paths corresponding to the bisecting line of each said square face, said dimples being arranged inside said isosceles triangle so that they do not intersect the bisecting lines.

11. The golf ball of claim 10 wherein each isosceles triangle has a substantially similar dimple pattern.

12. The golf ball of claim 10 wherein the dimples are of two different sizes.

13. The golf ball of claim 10 wherein each isosceles triangle has the same number of dimples.

14. The golf ball of claim 10 wherein the total number of dimples is 360.

15. The golf ball of claim 10 wherein the total number of dimples is 384.

16. The golf ball of claim 10 wherein the total number of dimples is 408.

17. The golf ball of claim 10 wherein the total number of dimples is 432.

18. The golf ball of claim 10 wherein the total number of dimples is 384 and said dimples are triangular in shape.

20. The golf ball of claim 18 wherein the total number of dimples is 384 and said dimples are triangular in shape.

19. A golf ball having a spherical surface with a plurality of dimples thereon and six parting lines which do not intersect any dimples, said parting lines corresponding to circular paths which coextend with twelve bisecting lines, said bisecting lines corresponding to lines which bisect faces of a cube inscribed in said spherical surface, said lines forming four isosceles triangles from each face of said cube, said dimples being arranged so that they do not intersect the parting lines.
