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 an upper part and a lower part, wherein the upper part is rotatably joined to the lower part by an axial joint, wherein the insert structure is transferable from an open position to a closed position upon rotation of said upper part around said axial joint; wherein the insert structure in said open position is adapted for insertion in the wheel concentrically to the axis of rotation of the wheel and wherein the insert structure in said closed position is adapted for fixating the insert structure in said wheel upon transfer to the closed position after insertion in the wheel,

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

a locking mechanism comprising at least a detachable locking bolt 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 upper part comprises an inferior surface and the lower part comprises a superior surface such that the inferior surface abuts the superior surface when the insert structure is in the closed position.

3. The device according to claim 1 , wherein the upper part of the insert structure forms an angle with the lower part of the insert structure when in the open position.

4. The device according to claim 1 , wherein the upper part and the lower 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.

5. The device according to claim 4 , wherein the first through hole of the upper part and the second through hole of the lower part are concentric when the insert structure is in the closed position and wherein the diameter of the first through hole is larger than the diameter of the second through hole.

6. The device according to claim 1 , wherein the lower part comprises a first guard and the upper part comprises a second guard such that the first guard partially surrounds the upper part and the second guard partially surrounds the lower part when the insert structure is in the closed position.

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

8. The device according to claim 7 , wherein the first wedge and the second wedge are arranged on opposite sides of the concentric diameters of the first through hole and the second through hole of the upper and lower parts of the insert structure.

9. The device according to claim 7 , 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 open position.

10. The device according to claim 7 , 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 closed position.

11. The device according to claim 7 , wherein the first wedge and the second wedge are configured to release the wheel of the vehicle when the insert structure is in the open position.

12. 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 though hole are configured to be aligned with each other; and

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

13. The device according to claim 12 , wherein the insert sleeve comprises recesses and protrusions configured to engage with corresponding recesses and protrusions of the main module.

14. The device according to claim 12 , further comprising a locking cap adapted to be rotationally secured to the main module, the locking cap comprising a fourth through hole adapted to receive the detachable locking bolt, and recesses and protrusions configured to engage with corresponding recesses and protrusions of the insert sleeve.

15. The device according to claim 14 , wherein the detachable locking bolt comprises a key hole and is operable by turning a key in the lock and wherein the detachable locking bolt is configured to be inserted via a front side of the device and secured in the axial direction by engaging the locking protrusion of the center bolt.
