Abstract

A spherical sport ball may include a casing that includes first and second substantially hemispherical panel components. Each substantially hemispherical panel component may be a unitary structure having a central panel and a plurality of polygonal peripheral panels adjacent to the central panel. In addition, the first substantially hemispherical panel component may be joined with the second substantially hemispherical panel component at a non-linear, circumferential seam between peripheral panels of the first hemispherical panel component and peripheral panels of the second hemispherical panel component.

Claims

1. A spherical sport ball comprising:

a casing that includes first and second substantially hemispherical panel components, each substantially hemispherical panel component being a unitary structure having a central panel and a plurality of polygonal peripheral panels adjacent to the central panel;

wherein the first substantially hemispherical panel component is joined with the second substantially hemispherical panel component at a non-linear, circumferential seam between peripheral panels of the first hemispherical panel component and peripheral panels of the second hemispherical panel component;

each of the substantially hemispherical panel components further including a plurality of flange areas extending from edges of the polygonal peripheral panels, the flange areas of each of the polygonal peripheral panels being joined to flange areas of adjacent polygonal peripheral panels.

2. The ball of claim 1, wherein the central panel has a polygonal shape, and wherein sides of the central panel are defined by elongated indentations in the casing.

3. The ball of claim 2, wherein the central panel has a pentagonal shape.

4. The ball of claim 3, wherein the polygonal peripheral panels are pentagonal, and wherein the pentagonal peripheral panels are oriented with a vertex pointed in a direction extending radially away from a center of the central panel.

5. The ball of claim 2, wherein the elongated indentations further define at least one side of each polygonal peripheral panel.

6. The ball of claim 1, wherein at least some of the polygonal peripheral panels have a pentagonal shape.

7. The ball of claim 1, wherein the non-linear, circumferential seam is formed by welding.

8. The ball of claim 1, wherein flange areas forming the edge portions of the peripheral panels of the first hemispherical panel component are joined to flange areas of adjacent peripheral panels of the first hemispherical panel component.

9. The ball of claim 1, wherein flange areas of the first hemispherical panel component are joined to flange areas of the second hemispherical panel component to form the circumferential seam.

10. The ball of claim 8, wherein the flange areas forming the edge portions of the peripheral panels of the first hemispherical panel component are joined to the flange areas of adjacent peripheral panels of the first hemispherical panel component by welding.

11. The ball of claim 8, wherein the flange areas of adjacent peripheral panels of the first hemispherical panel component taper to a vertex between the adjacent peripheral panels.

12. The ball of claim 1, wherein the flange areas of adjacent peripheral panels of the first hemispherical panel component are coextensive at a vertex between the adjacent peripheral panels of the first hemispherical panel component.

13. The ball of claim 1, wherein an intersection of the flange areas of adjacent peripheral panels of the first hemispherical panel component terminate at a stress relief opening at a vertex between the adjacent peripheral panels.

14. A spherical sport ball comprising:

a casing that includes first and second substantially hemispherical panel components, each substantially hemispherical panel component being a unitary structure having a polygonal central panel and a plurality of polygonal peripheral panels adjacent to the central panel;

wherein sides of the polygonal central panel are defined by elongated indentations in the casing, the elongated indentations further defining at least one side of each polygonal peripheral panel;

wherein the hemispherical panel components include flange areas that form edge portions of the peripheral panels, the flange areas of each of the polygonal peripheral panels being joined to flange areas of adjacent polygonal peripheral panels; and

wherein the flange areas of adjacent peripheral panels of the first hemispherical panel component are coextensive at a vertex between the adjacent peripheral panels.

15. The ball of claim 14, wherein the indentations are elongate regions of the casing that have been compressed.

16. The ball of claim 14, wherein the central panels have a regular pentagonal shape, the peripheral panels have a regular pentagonal shape, and the indentations in the casing are arranged to resemble seams between the panels of a pentagonal panel pattern.

17. The ball of claim 14, wherein the first substantially hemispherical panel component is joined with the second substantially hemispherical panel component at a circumferential seam between peripheral panels of the first hemispherical panel component and peripheral panels of the second hemispherical panel component.

18. A sport ball comprising:

a casing that includes a panel component having a unitary structure and including a pentagonal central panel and a plurality of polygonal peripheral panels adjacent to the central panel;

wherein each side of the pentagonal central panel is defined by an elongated indentation in the casing; and

wherein a side of each polygonal peripheral panel is defined by one of the indentations that also defines one of the sides of the pentagonal central panel;

the panel component further including a plurality of flange areas extending from edges of the polygonal peripheral panels, the flange areas of each of the polygonal peripheral panels being joined to flange areas of adjacent polygonal peripheral panels.

19. The ball of claim 18, wherein the pentagonal central panel has a convex pentagonal shape.

20. The ball of claim 19, wherein the central panel has a regular pentagonal shape.

21. The ball of claim 18, wherein each of the polygonal peripheral panels has a convex polygonal shape.

22. The ball of claim 21, wherein each of the polygonal peripheral panels has a regular pentagonal shape.

23. The ball of claim 18, wherein the pentagonal central panel has a regular pentagonal shape, each of the polygonal peripheral panels has a regular pentagonal shape, and the indentations in the casing are arranged to resemble seams between the panels of a pentagonal panel pattern.

24. The ball of claim 18, wherein the polygonal peripheral panels are pentagonal, and wherein the pentagonal peripheral panels are oriented with a vertex pointed in a direction extending radially away from a center of the pentagonal central panel.

25. The ball of claim 18, wherein the panel component is joined to at least one additional panel component having substantially the same configuration.

26. The ball of claim 25, wherein each panel component is a substantially hemispherical panel component and the ball is spherical.
