Abstract

A valve for a ball includes a casing and a core. The core is arranged at least partially inside the casing. The core comprises a first sealing area with a plurality of sections which have alternating concave and convex curvatures.

Claims

1. A valve for a ball comprising:

(a) a casing; and

(b) a core which is at least partially arranged inside the casing,

wherein the core comprises a first sealing area with a plurality of sections, wherein the sections have alternating concave and convex curvatures; and

define substantially semicircular cross-sections.

2. The valve according to claim 1, wherein the casing comprises a second sealing area, wherein the second sealing area engages the first sealing area.

3. The valve according to claim 2, wherein the second sealing area comprises curvature radii which substantially correspond to curvature radii of the first sealing area.

4. The valve according to claim 1, wherein the first sealing area is continuously curved.

5. The valve according to claim 2, wherein the core comprises at least one third sealing area with a first edge which engages a corresponding second edge of the casing.

6. The valve according to claim 5, wherein the at least one third sealing area has a larger diameter than the first sealing area.

7. The valve according to claim 1, wherein the casing comprises an outer end with a cover area, wherein the cover area has a larger diameter than an inner end of the casing.

8. The valve according to claim 7, wherein at least one receptacle for receiving at least one lighting means is arranged at the outer end of the casing.

9. The valve according to claim 8, wherein the casing comprises a substantially transparent material.

10. The valve according claim 9, wherein at least one projection for collecting and emitting light from the at least one lighting means is arranged on the cover area.

11. The valve according to claim 1, wherein the casing comprises a recess for an electromagnetic coil at an inner end of the casing.

12. A ball comprising the valve of claim 1.

13. The ball according to claim 12, further comprising:

an electromagnetic coil;

an energy storage which can be inductively charged by the electromagnetic coil; and

an electronic device.

14. The ball according to claim 13, wherein the electromagnetic coil is arranged at a bladder of the ball.

15. The ball according to claim 13, wherein at one receptacle for receiving at least one lighting means is arranged at an outer end of the casing of the valve and wherein at least one lighting means is arranged in the at least one receptacle as a display device for the electronic device.

16. The valve according to claim 1, wherein an inner end of the core extends beyond the casing.

17. The valve according to claim 16, wherein the inner end of the core defines a hemisphere.

18. The valve according to claim 1, wherein the plurality of sections comprises at least two convex sections having at least one concave section arranged therebetween.

19. The valve according to claim 5, wherein the third sealing area is arranged toward an outer end of the core, with respect to the first sealing area.

20. The valve according to claim 8, wherein the core is arranged toward an inner end of the casing, with respect to the at least one receptacle.

21. The valve according to claim 13, wherein the electromagnetic coil is arranged about a recess at an inner end of the casing.
