Abstract

Claims (57)

1. A wheel holder for fastening to a wheel, the wheel holder comprising:

at least two arms extending from a base plate of the wheel holder in a radial direction outward; each of the arms having at least one stationary element and at least one movable element that is movable with respect to the at least one stationary element in the radial direction;

a central rotation element that is disposed in a center of the wheel holder such that it can rotate;

at least two coupling elements each extending between one of the movable elements and the central rotation element such that the movable elements are movable in the radial direction by rotation of the central rotation element;

wherein the central rotation element is attached to the base plate of the wheel holder via a freewheeling system, and wherein the freewheeling system has at least one operating state in which the central rotation element is rotatable in a freewheeling direction and rotation of the central rotation element in a blocking direction opposite to the freewheeling direction is blocked;

wherein the wheel holder further comprises a clamping device which is adapted to apply a force to the freewheeling system in a tensioned state in order to apply additional forces which are directed towards the center of the wheel holder, to the movable elements by rotation of the freewheeling system;

wherein the clamping device comprises a clamping handle and a clamping force transmitting element which is designed to transfer a force exerted on the clamping handle to the freewheeling system;

wherein the clamping device comprises a locking mechanism which is designed to lock the clamping device in the tensioned state; and

wherein the clamping force transmitting element comprises a rod, a chain, a wire or cable pull, a belt and/or a hydraulic system.

2. The wheel holder according to claim 1 ,

wherein the freewheeling system is switchable between a first operating state in which the central rotation element is rotatable in clockwise direction and rotation of the central rotation element in anticlockwise direction is blocked, and a second operating state in which the central rotation element is rotatable in anticlockwise direction and rotation of the central rotation element in clockwise direction is blocked.

3. The wheel holder according to claim 2 , wherein the freewheeling system can be switched into a third operating state in which the central rotation element is rotatable in both directions.

4. The wheel holder according to claim 1 ,

wherein the clamping device comprises a locking mechanism which is designed to lock the clamping device in the tensioned state.

5. The wheel holder according to claim 4 , wherein the locking mechanism comprises a releasable ratchet mechanism.

6. The wheel holder according to claim 1 ,

wherein the freewheeling system comprises a main body rotatably attached to the base plate, as well as a rotation body connected to the central rotation element, and wherein the clamping force transmitting element is connected to the main body of the freewheeling system.

7. The wheel holder according to claim 1 ,

wherein the wheel holder comprises three arms.

8. The wheel holder according to claim 7 , wherein the three arms are arranged at angular distances of 120° about the center of the wheel holder.

9. A method of mounting the wheel holder according to claim 1 to a wheel, said method comprising the steps of:

bringing the freewheeling system into a mounting state in which the movable elements are movable outward in a radial direction and inward movement of the movable elements is blocked;

moving the movable elements outward in radial direction so as to increase the lengths of the arms;

applying the wheel holder to the wheel; and

bringing the freewheeling system into a fixing state in which the movable elements are movable inward in radial direction and outward movement of the movable elements is blocked; and

moving the movable elements in a direction towards the center so as to fix the wheel holder to the wheel.

10. A method of releasing the wheel holder according to claim 1 from a wheel, said method comprising:

releasing a clamping device and/or bringing the freewheeling system into a mounting state in which the movable elements can be moved outward in radial direction and inward movement of the movable elements is blocked;

moving the movable elements outward in radial direction so as to increase the lengths of the arms; and

removing the wheel holder from the wheel.

11. A wheel holder for fastening to a wheel, the wheel holder comprising:

at least two arms extending from a base plate of the wheel holder in a radial direction outward; each of the arms having at least one stationary element and at least one movable element that is movable with respect to the at least one stationary element in the radial direction;

a central rotation element that is disposed in a center of the wheel holder such that it can rotate;

at least two coupling elements each extending between one of the movable elements and the central rotation element such that the movable elements are movable in the radial direction by rotation of the central rotation element;

wherein the central rotation element is attached to the base plate of the wheel holder via a a freewheeling system, and wherein the freewheeling system has at least one operating state in which the central rotation element is rotatable in a freewheeling direction and rotation of the central rotation element in a blocking direction opposite to the freewheeling direction is blocked;

further comprising at least one drive device which is connected to one of the movable elements via a force transmitting element and is designed to apply to said one movable element a force directed towards the center of the wheel holder via the force transmitting element;

wherein the force transmitting element extends substantially parallel to one of the arms or along one of the arms, or wherein the force transmitting element comprises a chain, a wire, a cable pull, or a belt or a rod;

wherein the at least one drive device comprises a wheel, a roller or a drum; and

wherein the force transmitting element is adapted to be wound onto the wheel, the roller or the drum.

12. The wheel holder according to claim 11 ,

wherein the at least one drive device is arranged outside of the center of the wheel holder.

13. The wheel holder according to claim 12 , wherein the at least one drive device is arranged in a region between two arms of the wheel holder.

14. The wheel holder according to claim 11 , wherein the wheel, the roller or the drum can be rotated about an axle that is aligned orthogonal to a common plane of the arms.

15. The wheel holder according to claim 11 ,

wherein the freewheeling system is switchable between a first operating state in which the central rotation element is rotatable in clockwise direction and rotation of the central rotation element in anticlockwise direction is blocked, and a second operating state in which the central rotation element is rotatable in anticlockwise direction and rotation of the central rotation element in clockwise direction is blocked.

16. The wheel holder according to claim 15 , wherein the freewheeling system can be switched into a third operating state in which the central rotation element is rotatable in both directions.
