Abstract

A basketball including a carcass, cover panels, and cover strips. The carcass has an outer surface defining a first set of channels and cover panels regions between the first set of channels. The panels are respectively positioned over the panel regions and are spaced apart from each other. The strips are positioned over the channels. The strips have inner and outer surfaces extending between first and second sidewalls. The strips have a thickness that is measured radially from a centerpoint from the inner to the outer surface, and a width that is measured from the first to the second sidewall. At least one groove is formed into the outer surface. The groove has a width that extends between 20 to 70 percent of the width of the strip and has a maximum depth from the outer surface that is at least 50 percent of the maximum thickness of the strip.

First claim

What is claimed is:

1. A generally spherical basketball defining a center point, the basketball comprising:
a carcass having an outer surface defining a first set of channels and a plurality of cover panel regions between the first set of channels;
a plurality of cover panels respectively positioned over the plurality of cover panel regions and spaced apart from each other, the cover panels having peripheral edges; and
a plurality of elongated cover strips positioned over the first set of channels and between the peripheral edges of the spaced-apart cover panels, the cover strips having inner and outer surfaces extending between first and second side walls, a thickness measured in a direction extending radially from the center point from the inner surface to the outer surface of the cover strip, and a width measured from the first side wall to the second side wall, at least one narrow elongate groove being formed into the outer surface of the cover strips, the groove having a width that extends between the range of 20 to 60 percent of the width of the cover strip and having a maximum depth from the outer surface of the cover strip that is at least 50 percent of the maximum thickness of the cover strip, the outer surface of the cover strip and the first and second side walls of the cover strip forming first and second edges, respectively, and the at least one elongate groove and the outer surface of the cover strip forming third and fourth edges, wherein the thickness of the cover strip at the first edge is greater than the thickness of the cover strip at the third edge, and wherein the thickness of the cover strip at the second edge is greater than the thickness of the cover strip at the fourth edge.

2. The basketball of claim 1 , wherein the plurality of elongated cover strips define a collective first total length and wherein the at least one elongate groove defines a collective second total length that is at least 20 percent of the first total length.

3. The basketball of claim 2 , wherein the plurality of elongated cover strips is a collection of interconnected cover strips, and wherein the at least one elongate groove is formed in each of the interconnected cover strips.

4. The basketball of claim 3 , wherein the second total length is substantially the same as the first total length.

5. The basketball of claim 1 , wherein one or more of the first, second, third and fourth edges are rounded.

6. The basketball of claim 1 , wherein the cover panels are attached to the outer surface of the carcass at the cover panel regions.

7. The basketball of claim 1 , wherein the cover strips are formed at least in part of a synthetic leather.

8. The basketball of claim 1 , wherein the cover strips are formed of at least a first material positioned at the outer surface of the cover strips, 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.

9. The basketball of claim 1 , wherein the at least one groove forms a general U-shape when viewed from the perspective of a lateral cross-sectional view of the cover strip.

10. The basketball of claim 1 , wherein the plurality of cover strips are adhesively bonded to the carcass.

11. The basketball of claim 1 , wherein the outer surface of the plurality of cover strips has a pebbled texture.
