Abstract

A golf ball is provided having a dimpled surface, the configuration of the dimples comprising a dimple-free equatorial line on the ball dividing the ball into two hemispheres, with each hemisphere having substantially identical dimple patterns. The dimple pattern of each hemisphere comprises a first plurality of dimples extending in at least two spaced clockwise arcs between the pole and the equator of each hemisphere, a second plurality of dimples extending in at least two spaced counterclockwise arcs between the pole and the equator of each hemisphere, and a third plurality of dimples substantially filling the surface area between the first and second plurality of dimples.

Claims

1. A golf ball having a dimpled surface, the configuration of said dimpled surface comprising

a dimple-free equatorial line on said ball dividing said ball into two hemispheres with each hemisphere having a pole and substantially identical dimple patterns, each hemispherical dimple pattern comprising

at least two spaced imaginary arcs extending clockwise between said pole and said equator on said surface;

at least two spaced imaginary arcs extending counterclockwise between said pole and said equator on said surface;

a plurality of dimples extending along each of said arcs between said pole and said equator; and

a second plurality of dimples substantially filling the surface area enclosed within said arcs.

2. The golf ball of claim 1 wherein each of said clockwise arcs has the same number of dimples and each of said counterclockwise arcs have the same number of dimples.

3. The golf ball of claim 1 wherein each of said arcs terminates at one end within a common polar dimple.

4. The golf ball of claim 1 wherein a dimple is located substantially at each point on the surface of said hemisphere where said clockwise arcs cross said counterclockwise arcs.

5. The golf ball of claim 1 wherein said dimples are of at least two different diameters.

6. The golf ball of claim 5 wherein each of said clockwise arcs has the same dimple configuration and each of said counterclockwise arcs has the same dimple configuration.

7. The golf ball of claim 1 wherein said arcs are helices.

8. The golf ball of claim 1 wherein each of said arcs on said hemisphere extends substantially 360°

about the hemisphere between the pole and the equator.

9. The golf ball of claim 1 wherein each of said arcs on said hemisphere extends less than 360°

about the hemisphere between the pole and the equator.

10. The golf ball of claim 1 wherein each of said arcs on said hemisphere extends more than 360°

about the hemisphere between the pole and the equator.

11. The golf ball of claim 1 wherein none of said dimples overlap each other.

12. The golf ball of claim 1 wherein said two hemispheres are rotated with respect to each other a predetermined degree about an axis through the said poles.

13. A method of locating dimples on the surface of a golf ball comprising

designating opposite pole locations and an equator between said poles to create two equal hemispheres;

establishing at least two arcs extending clockwise between said pole and said equator on the surface of each of said hemispheres;

establishing at least two arcs extending counterclockwise between said pole and said equator on the surface of each of said hemispheres;

locating a plurality of dimples along said arcs; and

substantially filling the area within said arcs with dimples, the total number of said dimples being the same for both hemispheres.

14. The method of claim 13 wherein each of said arcs terminates in a common polar dimple.

15. The method of claim 13 further comprising locating a dimple substantially at each point where said clockwise and counterclockwise arcs intersect.

16. The method of claim 13 wherein said arcs are helices.

17. The method of claim 13 wherein said arcs on the surface of said hemispheres extend substantially 360°

between said poles and said equator.

between said poles and said equator.

19. The method of claim 13 wherein said arcs on the surface of said hemispheres extend more than 360°

between said pole and said equator.

20. The method of claim 13 wherein said dimples are of at least two different diameters.
