A golf ball comprising a core and a cover layer, wherein the cover layer provides one or more deep dimples having two or more different radii is disclosed. The deep dimples(s) extend(s) through the cover layer to and/or into a layer or component underneath. The cover may be a single layer or it may include multiple layers. The deep dual dimples may be spherical or non-spherical, and the portion of the dimple that extends to or into the next inner layer may be the same or different shape as the outer portion of the dimple.
1. A golf ball comprising:
a core; and
a cover layer disposed on said core, said cover layer having an outer surface and defining a plurality of dimples along said outer surface of said cover layer, wherein at least one of said dimples extends through said cover layer at last to said core and includes a first region defined by a first radius and having a first span and a second region defined by a second radius and having a second span, wherein said second radius is less than said first radius.
2. The golf ball of claim 1 , wherein said first region of said dimple is defined by said cover layer and said second region of said dimple is defined by said core.
3. The golf ball of claim 1 , wherein said first span is from about 0.030 inches to about 0.250 inches.
4. The golf ball of claim 1 , wherein said second span is from about 0.005 inches to about 0.160 inches.
5. The golf ball of claim 1 , wherein said first region has a depth of from about 0.005 inches to about 0.135 inches.
6. The golf ball of claim 1 , wherein said second region has a depth of from about 0.005 inches to about 0.135 inches.
7. The golf ball of claim 1 , wherein said first region is in the form of a first shape and said second region is in the form of a second shape, said first and second shapes as viewed in a direction extending along a diameter of said golf ball.
8. The golf ball of claim 7 , wherein said first shape and said second shape are selected from the group of shapes consisting of circular, elliptical, oval, square, triangular, and polygonal.
9. The golf ball of claim 7 , wherein said first shape is the same as said second shape.
10. The golf ball of claim 1 , wherein said first shape is different than said second shape.
11. The golf ball of claim 1 , wherein the depth of said first region is from about 40% to about 80% of the total depth of said dimple extending though said cover layer.
12. The golf ball of claim 1 , wherein the depth of said second region is from about 20% to about 60% of the total depth of said dimple extending through said cover layer.
13. A golf ball comprising;
a core;
a mantle layer disposed on said core; and
a cover layer disposed on said mantle layer, said cover layer having an outer surface and defining a plurality of dimples along said outer surface of said cover layer, wherein at least one of said dimples extends trough said cover layer at least to said mantle layer and includes a first region defined by a first radius and having a first span, and a second region defined by a second radius and having a second span.
14. The golf ball of claim 13 , wherein said first span is from about 0.030 inches to about 0.250 inches.
15. The golf ball of claim 13 , wherein said second span is from about 0020 inches to about 0.160 inches.
16. The golf ball of claim 13 , wherein said first region has a depth of from about 0.005 inches to about 0.135 inches.
17. The golf ball of claim 13 , wherein said second region has a depth of from about 0.005 inches to about 0.135 inches.
18. The golf ball of claim 13 , wherein said first region is in the form of a first shape and said second region is in the form of a second shape, said first and second shapes as viewed in a direction extending along a diameter of said golf ball.
19. The golf ball of claim 18 , wherein said first shape is selected from the group consisting of circular, elliptical, oval, square, triangular, and polygonal.
20. The golf ball of claim 18 , wherein said first shape is the same as said second shape.
21. The golf ball of claim 18 , wherein said first shape is different than said second shape.
22. The golf ball of claim 13 , wherein the depth of said first region is from about 40% to about 80% of the total depth of said dimple extending trough said cover layer.
23. The golf ball of claim 13 , wherein the depth of said second region is from about 20% to about 60% of the total depth of said dimple extending through said cover layer.
