Abstract

Described are balls for a ball sport, wherein the ball includes at least one heating element.

Claims

1. A ball for a ball sport, wherein the ball comprises at least one heating element.

2. The ball according to claim 1, wherein the at least one heating element is an electrically conductive fabric.

3. The ball according to claim 1, wherein the at least one heating element is a radiant heater.

4. The ball according to claim 3, wherein the radiant heater is arranged substantially at a geometric center of the ball.

5. The ball according to claim 1, wherein the at least one heating element is a conductive polymer.

6. The ball according to claim 1, wherein the ball is inflatable.

7. The ball according to claim 1, wherein the ball comprises a bladder in its interior and the at least one heating element is arranged on the bladder.

8. The ball according to claim 7, wherein the at least one heating element is a heating wire that is vapor-deposited or imprinted on the bladder or a wire mesh that is vapor-deposited or imprinted on the bladder.

9. The ball according to claim 1, wherein the at least one heating element is arranged within an outer casing of the ball.

10. The ball according to claim 1, wherein the ball comprises a valve that comprises a first end, which is arranged outside the outer casing of the ball and a second end, which is arranged within the outer casing of the ball, whereby the at least one heating element is arranged at the second end of the valve.

11. A ball for a ball sport, wherein the ball comprises at least one heating element and at least one electrical power source, wherein the at least one electrical power source provides an electrical current for heating the at least one heating element and with which it is electrically connected.

12. The ball according to claim 11, wherein the at least one electrical power source is arranged substantially opposite a valve of the ball, or in a geometric center of the ball.

13. The ball according to claim 11, wherein the at least one electrical power source is a battery or an accumulator battery.

14. The ball according to claim 11, wherein the at least one electrical power source can be charged by means of electromagnetic induction.

15. The ball according to claim 11, further comprising at least one electric generator that is configured to convert rotational energy and/or kinetic energy of the ball into current, which can be fed to the at least one heating element and/or the at least one electrical power source.

16. The ball according to claim 11, further comprising a regulator, which is suitable for regulating a current for heating the at least one heating element in such a manner that a temperature of the ball substantially reaches a predetermined value.

17. The ball according to claim 16, wherein the predetermined value ranges between 5°

C. and 15°

C.

18. The ball according to claim 16, wherein the regulator is a switch that is configured to automatically switch on the current for heating the at least one heating element when the temperature of the ball drops below a first predefined threshold value, and to automatically switch the current off when the temperature of the ball rises above a second predetermined threshold value.

19. The ball according to claim 16, wherein the temperature of the ball is a temperature of a filler gas of the ball or a temperature of the outer casing of the ball.

20. The ball according to claim 16, wherein the at least one heating element and/or the at least one electrical power source and/or the regulator are arranged in such a manner that a center of mass of the ball substantially coincides with a geometric center of the ball.

21. The ball according to claim 16, wherein the at least one heating element and/or the at least one electrical power source and/or the regulator are arranged in such a manner that a distribution of mass of the ball is substantially spherically symmetric.

22. A ball for a ball sport, wherein the ball comprises a bladder in its interior and at least one heating element is arranged on the bladder in such a manner that a center of mass of the ball substantially coincides with a geometric center of the ball.

23. The ball according to claim 22, wherein the at least one heating element is a heating wire that is vapor-deposited or imprinted on the bladder or a wire mesh that is vapor-deposited or imprinted on the bladder.
