Abstract

A sport ball may include a casing, a restriction structure, and a bladder. The casing forms at least a portion of an exterior surface of the ball. The restriction structure is located within the casing and includes a textile element having a seamless portion with a non-planar configuration. The bladder is also located within the casing. The textile element may be a knitted fabric. Although the restriction structure may be seamless, the restriction structure may also include at most one seam or multiple seams that joins edges of the textile element. In addition, the seamless portion of the textile element may cover at least thirty percent or more of the surface of the bladder.

Claims

1. A sport ball comprising:

a casing that forms at least a portion of an exterior surface of the ball;

a bladder located within the casing; and

a restriction structure located within the casing, the restriction structure including a textile element knitted to have a seamless one-piece portion with a non-planar configuration that covers at least eighty percent of a surface of the bladder, the seamless portion having a plurality of circular courses;

wherein the restriction structure has a pre-formed non-planar configuration shaped to conform with both an interior surface of the casing and an exterior surface of the bladder.

2. The sport ball recited in claim 1, wherein the restriction structure includes at most one seam that joins edges of the textile element.

3. The sport ball recited in claim 1, wherein the seamless portion of the textile element has a configuration of a sphere.

4. The sport ball recited in claim 1, wherein the seamless portion of the textile element has a configuration of a portion of a sphere.

5. The sport ball recited in claim 1, wherein the seamless portion of the textile element covers at least ninety-five percent of a surface of the bladder.

6. The sport ball recited in claim 1, wherein the bladder is located within the restriction structure.

7. The sport ball recited in claim 1, wherein the restriction structure is embedded within a material of the bladder.

8. A sport ball comprising:

a casing that forms at least a portion of an exterior surface of the ball;

a restriction structure located within the casing; and

a bladder located within the restriction structure,

wherein the restriction structure includes a textile element knitted to have a seamless one-piece portion with a non-planar configuration that covers at least eighty percent of a surface of the bladder, and the restriction structure is substantially free of bunching, folding, and overlapping.

9. The sport ball recited in claim 8, wherein the seamless portion of the textile element covers at least ninety-five percent of the surface of the bladder.

10. The sport ball recited in claim 8, wherein the restriction structure includes at most one seam that joins edges of the textile element.

11. The sport ball recited in claim 8, wherein the seamless portion of the textile element has a configuration of a portion of a sphere.

12. A sport ball consisting of:

a casing that forms at least a portion of an exterior surface of the ball;

a restriction structure located within the casing; and

a bladder located within the restriction structure;

wherein the restriction structure is a textile element with a one-piece seamless portion, the seamless portion being knitted into a pre-formed partially-spherical configuration that covers at least eighty percent of a surface of the bladder.

13. The sport ball recited in claim 12, wherein the restriction structure includes at most one seam that joins edges of the textile element.

14. The sport ball recited in claim 12, wherein the seamless portion of the textile element covers at least ninety-five percent of the surface of the bladder.

15. A method of manufacturing a sport ball, the method comprising:

providing an inflatable bladder and a casing;

knitting a textile element with a flat knitting process, the textile element being formed in the flat-knitting process to have a one-piece seamless portion with a non-planar configuration that covers at least eighty percent of a surface of the bladder; and

locating the textile element between the inflatable bladder and the casing of the sport ball.

16. The method recited in claim 15, wherein the step of knitting further includes joining the textile element to another textile element with at most a single seam.

17. A method of manufacturing a sport ball, the method comprising:

providing an inflatable bladder and a casing;

utilizing a knitting process to mechanically-manipulate at least one yarn to form a textile element, the knitting process forming the textile element to have a plurality of circular courses, and the knitting process shaping the textile element to have a partially spherical configuration that covers at least eighty percent of a surface of the bladder; and

locating the textile element between the inflatable bladder and the casing of the sport ball.

18. The method recited in claim 17, wherein the step of mechanically-manipulating includes forming the textile element with a knitting process.

19. A sport ball comprising:

a casing that forms at least a portion of an exterior surface of the ball;

a bladder located within the casing; and

a restriction structure located within the casing, the restriction structure including a textile element having a one-piece seamless portion knitted into a pre-formed non-planar configuration that covers at least eighty percent of a surface of the bladder, the seamless portion having a plurality of circular courses arranged to form the non-planar configuration.

20. The sport ball recited in claim 19, wherein the restriction structure includes at most one seam that joins edges of the textile element.

21. The sport ball recited in claim 19, wherein the seamless portion of the textile element has a configuration of a portion of a sphere.

22. The sport ball recited in claim 19, wherein the seamless portion of the textile element covers at least thirty percent of a surface of the bladder.

23. The sport ball recited in claim 19, wherein the seamless portion of the textile element covers at least ninety-five percent of a surface of the bladder.
