Wheel locking device

1. A device for locking the wheel of a vehicle, comprising:

a main module adapted to be attached to the wheel, and configured to cover nuts or bolts for attaching the wheel to the vehicle;

an insert structure comprising a first part and a second part, wherein the first part engages the second part, wherein the insert structure is transferable from a first position to a second position upon compression of a spring having two opposite ends abutting anchors formed in the first part and positioned on an outer circumference of the first part facing the second part; and wherein the insert structure in said second position is adapted for insertion in the wheel concentrically to the axis of rotation of the wheel and wherein the insert structure in said first position is adapted for fixating the insert structure in said wheel upon transfer to the first position after insertion in the wheel;

a center bolt adapted to be connected through the main module to the second part of the insert structure by threading; and

a locking mechanism comprising at least a locking bolt, and being adapted to be arranged in a locking state in which the locking mechanism prevents the center bolt from rotating relative the main module, and in an open state in which the locking mechanism allows the center bolt to rotate relative the main module.

2. The device according to claim 1 , wherein the first part comprises an inferior surface and the second part comprises a superior surface arranged such that the inferior surface is in constant contact with the superior surface.

3. The device according to claim 1 , wherein the first part and the second part of the insert structure comprise a first through hole and a second through hole respectively and wherein the first and second through holes are adapted to receive the center bolt.

4. The device according to claim 1 , wherein the second part comprises a first guard and the first part comprises a second guard such that the first guard at least partially surrounds the first part and the second guard at least partially surrounds the second part when the insert structure is in the second position.

5. The device according to claim 4 , wherein the first guard comprises a central protrusion forming a channel with a superior surface of the second part of the insert structure wherein the first part of the insert structure completely engages the channel when in the second position and partially engages the channel when in the first position.

6. The device according to claim 5 , wherein the spring is arranged to be positioned in the channel and exert opposing forces on the second part and on the first part such that the insert structure is normally in the first position.

7. The device according to claim 6 , wherein the spring represents a leaf spring comprising an arc-shaped length and at least two legs wherein the arc-shaped length is arranged to abut the first guard of the second part and the at least two legs are arranged to abut the first part.

8. The device according to claim 1 , wherein the insert structure comprises a stopper inserted through the second part and the first part and configured to limit the movement of the first part relative to the second part such that the first and second through holes are concentric when in the first position.

9. The device according to claim 1 , wherein the first part of the insert structure and the second part of the insert structure comprise a first wedge and a second wedge respectively.

10. The device according to claim 9 , wherein the first wedge and the second wedge are arranged on opposite sides of the diameters of the first through hole and the second through hole of the upper and second parts of the insert structure.

11. The device according to claim 9 , wherein the first wedge and the second wedge determine an outer diameter of the insert structure and wherein said outer diameter decreases when the insert structure transfers to the second position.

12. The device according to claim 9 , wherein the first wedge and the second wedge are configured to secure the insert structure by engaging the wheel of the vehicle when the insert structure is in the first position and to release the wheel of the vehicle when the insert structure is in the second position.

13. The device according to claim 1 , wherein opposing forces are applied to the first part and to the second part towards the center of the insert structure to transfer from the first position to the second position and released to transfer from the second position to the first position.

14. The device according to claim 13 , wherein the first part of the insert structure is configured to translate towards the second part of the insert structure in a direction parallel to a plane formed by the contacting inferior surface and superior surface when transferring from the first position to the second position and to translate away from the second part of the insert structure in a direction parallel to a plane formed by the contacting inferior surface and superior surface when transferring from the second position to the first position.

15. The device according to claim 1 , wherein the locking mechanism comprises:

a locking protrusion formed in the center bolt;

an insert sleeve having a third through hole and being adapted to be rotationally secured to the main module; and

a detachable locking bolt adapted to be inserted into the main module via the third through hole and the locking protrusion;

wherein the locking protrusion and the third through hole are configured to be aligned with each other; and

the detachable locking bolt is adapted to prevent the center bolt from rotating relative the insert structure.
