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.

Claims

1. A generally spherical basketball defining a center point, the basketball comprising:

a carcass having an outer surface that includes a set of outwardly extending ribs and a plurality of cover panels regions between the ribs, the ribs including an elongated central surface extending between first and second rib side walls, the ribs having a rib height that is measured in a direction extending radially from the center point from a first point positioned at the same radial dimension as the outer surface of the cover panel region to the central surface, the central surface of the rib having first and second edges formed by the central surface meeting the first and second rib sidewalls, respectively; and

a plurality of cover panels respectively positioned over the plurality of cover panel regions, the central surface of the ribs and the outer surface of the cover panels collectively fonning the outer surface of the basketball, the central surface having a central surface width defined by the exposed distance from the first rib side wall to the second rib side wall, at least one narrow elongate channel being formed into the central surface of the rib, the channel having a width that extends between the range of 20 to 60 percent of the width of the central surface of the rib and a maximum depth that is greater than or equal to the maximum rib height, the central surface being generally smooth and non-pebbled, the at least one elongate channel and the central surface defining third and fourth edges, the rib height at the first edge being greater than the rib height at the third edge, and the rib height at the second edge being greater than the rib height at the fourth edge.

2. The basketball of claim 1, wherein the set of outwardly extending ribs define a collective first total length and wherein the at least one elongate channel 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 set of outwardly extending ribs is a collection of interconnected ribs, wherein the at least one elongate channel is formed in each of the interconnected ribs.

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

6. The basketball of claim 1, wherein the at least one channel forms a general U-shape when viewed from the perspective of a lateral cross-sectional view of the rib.

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

5. A generally spherical basketball defining a center point, the basketball comprising:

a carcass having an outer surface that includes a set of outwardly extending ribs and a plurality of cover panels regions between the ribs, the ribs including an elongated central surface extending between first and second rib side walls, the ribs having a rib height that is measured in a direction extending radially from the center point from a first point positioned at the same radial dimension as the outer surface of the cover panel region to the central surface; and

a plurality of cover panels respectively positioned over the plurality of cover panel regions, the central surface of the ribs and the outer surface of the cover panels collectively forming the outer surface of the basketball, the central surface having a central surface width defined by the exposed distance from the first rib side wall to the second rib side wall, at least one narrow elongate channel being formed into the central surface of the rib, the channel having a width that extends between the range of 20 to 60 percent of the width of the central surface of the rib and a maximum depth that is at least 60 percent of the maximum rib height, the central surface of the rib has first and second edges formed by the central surface meeting the first and second rib sidewalls, respectively, and wherein the at least one elongate channel and the central surface define third and fourth edges, wherein the rib height at the first edge is greater than the rib height at the third edge, and wherein the rib height at the second edge is greater than the rib height at the fourth edge, each of the cover panels define a convex curved outer surface that curves toward the rib side walls, the central surface being curved from the first edge to the third edge and being curved from the second edge to the fourth edge.

8. The basketball of claim 5, wherein the at least one channel forms a general U-shape when viewed from the perspective of a lateral cross-sectional view of the rib.

9. The basketball of claim 5, wherein the set of outwardly extending ribs define a collective first total length and wherein the at least one elongate channel defines a collective second total length that is at least 20 percent of the first total length.

10. The basketball of claim 9, wherein the set of outwardly extending ribs is a collection of interconnected ribs, wherein the at least one elongate channel is formed in each of the interconnected ribs.

11. The basketball of claim 10, wherein the second total length is substantially the same as the first total length.
