Abstract

A generally spherical basketball defining a center point and including a carcass having an outer surface and a cover assembly positioned over the outer surface of the carcass. The cover assembly includes at least one cover panel. The cover panel has an outer surface including a valley base surface and first and second sets of spaced-apart projections. Each of the projections of the first and second sets of spaced-apart projections include first and second outermost surfaces, respectively. The first set of projections have an average height measured in a radial direction from the center point within the range of 0.2 to 2.0 mm from the valley base surface to the first outermost surface. The second set of projections have an average height measured in a radial direction from the center point within the range of 15 to 175 μm from the valley base surface to the second outermost surface.

First claim

What is claimed is:

1. A generally spherical basketball defining a center point, the basketball comprising:
a carcass having an outer surface;
a cover assembly positioned over the outer surface of the carcass, the cover assembly including at least one cover panel, the at least one cover panel having an outer surface including a valley base surface and first and second sets of spaced-apart projections, each of the projections of the first and second sets of spaced-apart projections including first and second outermost surfaces, respectively, the first set of projections having an average height measured in a radial direction from the center point within the range of 0.2 to 2.0 mm from the valley base surface to the first outermost surface, the second set of projections having an average height measured in a radial direction from the center point within the range of 5 to 175 μm from the valley base surface to the second outermost surface, the second set of spaced-apart projections being positioned between and not being positioned over the first set of spaced-apart projections, the first set of projections extending over a majority of an outer surface of the at least one cover panel, each of at least two of the projections of the first set of projections being substantially enclosed on all sides by the projections of the second set of projections.

2. The basketball of claim 1 , wherein the first set of spaced-apart projections are pebble-like projections having a pebbled outer surface that is free of any of the second set of spaced-apart projections.

3. The basketball of claim 1 , wherein the second set of spaced-apart projections are pebble-like projections.

4. The basketball of claim 2 , wherein the second set of spaced-apart projections are pebble-like projections.

5. The basketball of claim 1 , wherein the first set of spaced-apart projections have an average height within the range of 0.25 to 1.0 mm from the valley base surface to the first outermost surface.

6. The basketball of claim 1 , wherein the second set of spaced-apart projections have an average height within the range of 25 to 150 μm from the valley base surface to the second outermost surface.

7. The basketball of claim 5 , wherein the second set of spaced-apart projections have an average height within the range of 25 to 150 μm from the valley base surface to the second outermost surface.

8. The basketball of claim 1 , wherein the first set of spaced-apart projections have an average maximum width within the range of 1 to 5 mm, wherein the second set of spaced-apart projections have an average maximum width within the range of 30 to 600 μm, and wherein the first set of spaced-apart projections have an upper surface that is free of any of the second set of projections.

9. The basketball of claim 8 , wherein the first set of spaced-apart projections have an average maximum width within the range of 1.5 to 3.0 mm, and wherein the second set of spaced-apart projections have an average maximum width within the range of 20 to 500 μm.

10. The basketball of claim 1 , wherein two adjacent projections of the first set of projections are spaced apart from each other by a maximum width within the range of 150 to 1000 μm.

11. The basketball of claim 2 , wherein the first set of pebble-like spaced-apart projections are selected from the group consisting of irregularly shaped pebble-like projections, hemi-spherically shaped pebble-like projections, generally oval shaped pebble-like projections, generally triangular shaped pebble-like projections, generally square shaped pebble-like projections, generally rectangular shaped pebble-like projections, generally diamond shaped pebble-like projections, generally pentagon-shaped pebble-like projections, other polygonal shaped pebble-like projections, generally conical pebble-like projections, generally frustoconical pebble-like projections, generally cylindrical pebble-like projections, generally pyramid-shaped pebble-like projections, generally cubic pebble-like projections, and combinations thereof.

12. The basketball of claim 3 , wherein the second set of pebble-like spaced-apart projections are selected from the group consisting of irregularly shaped pebble-like projections, hemi-spherically shaped pebble-like projections, generally oval shaped pebble-like projections, generally triangular shaped pebble-like projections, generally square shaped pebble-like projections, generally rectangular shaped pebble-like projections, generally diamond shaped pebble-like projections, generally pentagon-shaped pebble-like projections, other polygonal shaped pebble-like projections, generally conical pebble-like projections, generally frustoconical pebble-like projections, generally cylindrical pebble-like projections, generally pyramid-shaped pebble-like projections, generally cubic pebble-like projections, and combinations thereof.

13. The basketball of claim 3 , wherein each of the spaced-apart projections of the second set of projection has a maximum length and a maximum width, and wherein the maximum length and the maximum width define an aspect ratio of within 0.2 and 5.0.

14. The basketball of claim 1 , wherein the outer surface of the carcass defines a first set of channels and a plurality of cover panel regions between the first set of channels, and wherein the at least one cover panel is a plurality of cover panels respectively positioned over the plurality of cover panel regions and spaced apart from each other.

15. The basketball of claim 14 , wherein a plurality of elongated cover strips are positioned over the first set of channels, and wherein the cover strips have an outer surface.

16. The basketball of claim 15 , wherein the outer surface of the elongated cover strips include the first set of spaced-apart projections.

17. The basketball of claim 15 , wherein the outer surface of the elongated cover strips include the first and second sets of spaced-apart projections.

18. The basketball of claim 1 , wherein the at least one cover panel is formed of at least a first material positioned at the outer surface of the at least one cover panel, and wherein the first material is selected from the group consisting of a natural rubber, a butyl rubber, natural leather, a polyurethane, a thermoplastic material, and a thermoset material.

19. The basketball of claim 1 , wherein the carcass is formed of at least a bladder, a layer of windings about the bladder and at least one layer of elastomeric material formed over the layer of windings.

20. The basketball of claim 3 , wherein the second set of pebble-like spaced-apart projections are generally circular shaped pebble-like projections.
