Abstract

A sport ball may incorporate a casing that includes a plurality of joined panels. At least one of the panels may have a first layer, a second layer, and a third layer. The casing defines at least one indentation in the exterior surface, and the first layer is bonded to the third layer adjacent to the indentation. In some configurations, the casing may also define at least one indentations in a surface of the third layer, which may correspond in location with the indentation in the exterior surface. Additionally, the sport ball may include an intermediate structure and a bladder located within the casing.

Claims

1. A sport ball comprising:

a casing that includes a plurality of joined panels, including at least a first panel having (a) a first layer including a polymer material and positioned to form a portion of an exterior surface of the ball, (b) a second layer including a polymer foam material and positioned inward and adjacent to the first layer, and (c) a third layer including a textile material and positioned inward and adjacent to the second layer, the casing defining at least one indentation in the exterior surface, the first layer being bonded directly to the third layer at the indentation; and

a bladder located within the casing;

wherein the indentation is spaced from edges of the panel.

2. The sport ball recited in claim 1, wherein the casing defines a second indentation in a surface of the third layer, the first layer being bonded to the third layer adjacent to the second indentation.

3. The sport ball recited in claim 1, wherein at least the first layer extends through the second layer in an area where the first layer is bonded to the third layer.

4. The sport ball recited in claim 1, wherein the second layer has (a) a first thickness adjacent to the area where the first layer is bonded to the third layer and (b) a second thickness spaced from the area where the first layer is bonded to the third layer, the first thickness being less than the second thickness.

5. The sport ball recited in claim 1, wherein at least one of the polymer material of the first layer and the polymer foam material of the second layer includes a thermoplastic polymer material.

6. The sport ball recited in claim 1, wherein an intermediate structure is located between the casing and the bladder.

20. The sport ball recited in claim 1, wherein the indentation extends through substantially all of a thickness of the first panel.

21. The sport ball recited in claim 1, wherein the indentation has a rounded cross-sectional configuration.

7. A sport ball comprising:

a casing including at least one panel defining a plurality of edges, the panel having a polymer foam layer and a pair of cover layers located on opposite sides of the polymer foam layer, the panel defining opposing indentations in the cover layers, the indentations being spaced inward from the edges, and the cover layers being bonded directly to each other at the indentations; and

a bladder located within the casing.

8. The sport ball recited in claim 7, wherein a first of the cover layers is formed from a polymer material and a second of the cover layers is formed from a textile material.

9. The sport ball recited in claim 7, wherein the cover layers extend into the polymer foam layer between the indentations.

10. The sport ball recited in claim 7, wherein the polymer foam layer has (a) a first thickness between the indentations and (b) a second thickness in an area spaced from the indentations, the first thickness being less than the second thickness.

11. The sport ball recited in claim 7, wherein an intermediate structure is located between the casing and the bladder.

19. The sport ball recited in claim 7, wherein the opposing indentations include a first indentation and a second indentation, and wherein the first indentation extends through more of a thickness of the panel than the second indentation.

22. The sport ball recited in claim 7, wherein the opposing indentations extend to an approximate midpoint of a thickness of the first panel.

12. A sport ball comprising:

a casing having an exterior surface facing outward from the ball and an opposite interior surface facing inward, the casing including a plurality of panels, the plurality of panels including a first panel having (a) an outer layer that defines a first indentation in the exterior surface of the casing, (b) an inner layer that defines a second indentation in the interior surface of the casing, and (c) a central layer, a majority of the outer layer of the first panel being spaced from the inner layer of the first panel by the central layer, and the outer layer of the first panel being secured to the inner layer of the first panel at the first indentation and the second indentation; and

a bladder located within the casing;

wherein the first panel has one or more peripheral edges joined to edges of adjacent panels of the casing to form one or more seams, each of the one or more seams projecting inward beyond portions of the first panel adjacent the one or more seams, the first indentation being spaced from the seams.

13. The sport ball recited in claim 12, wherein the first indentation is disposed opposite the second indentation.

14. The sport ball recited in claim 12, wherein the outer layer is formed from a polymer material and the inner layer is a textile material.

15. The sport ball recited in claim 12, wherein the central layer is a polymer foam layer.

16. The sport ball recited in claim 12, wherein an intermediate structure is located between the casing and the bladder.

17. The sport ball of claim 12,

wherein the first indentation and the second indentation are opposing indentations;

and

wherein a majority of the central layer is formed from a polymer foam material with a first thickness, and a portion of the central layer located between the indentations has a second thickness, the first thickness being greater than the second thickness.

18. The sport ball recited in claim 12, wherein the first indentation and the second indentation each have a substantially squared cross-sectional configuration.
