Abstract

An anti-skid device for a tyre of a vehicle wheel includes an anti-skid raceway designed to be placed on the circumferential tread of the tyre. An elongate element extends in sliding manner through rear attachment means arranged along the periphery of the rear edge of the raceway. Means for tightening the raceway include at least one guide member passing through the raceway to let a part of the elongate element slide freely transversely to the raceway, in front of the front edge of the raceway, elastically extensible means arranged along the elongate element, and securing means to connect at least one end of the elongate element to the front element.

Claims

1-7. -7. (canceled)

8. An anti-skid device for a tyre of a vehicle wheel, comprising:

an anti-skid raceway designed to be placed on the circumferential tread of the tyre,

means for securing the raceway on the circumferential tread of the tyre,

front attachment means arranged on the periphery of the front edge of the raceway,

a front element connected to the front attachment means and forming a stop against the front wall of the tyre after the securing means have been actuated,

rear attachment means arranged on the periphery of the rear edge of the raceway,

and at least one elongate element connected to the rear attachment means and forming a stop against the rear wall or the circumferential tread of the tyre after the securing means have been actuated,

wherein the raceway comprises flexible blocks distributed along a chain track forming a loop so that the raceway presents a continuous shape and the flexible blocks are spaced out along the chain track, and each flexible block comprises a flexible extension directed towards the rear of the rear edge of the raceway to form the rear attachment means.

9. The device according to claim 8, wherein the elongate element extends in sliding manner through the rear attachment means and the securing means comprise:

at least one guide member passing through the raceway to let a part of the elongate element slide freely transversely to the raceway, to the front of the front edge of the raceway,

elastically extensible means arranged along the elongate element,

and securing means to connect at least one end of the elongate element to the front element.

10. The device according to claim 9, wherein the elongate element is formed by two independent cables bordering two distinct angular sectors of the rear edge of the raceway and each following a passage of the guide member, and each of the cables comprises elastically extensible means.

11. The device according to claim 9, wherein the elastically extensible means of each of the cables are arranged on the part of the cable to the front of the front edge of the raceway.

12. The device according to claim 8, wherein the securing means collaborate with at least one hook securedly affixed to the front element.

13. The device according to claim 8, wherein the raceway is continuous and comprises flexible blocks spaced out along a chain track.

14. The device according to claim 12, wherein each block comprises a flexible extension directed towards the rear of the rear edge of the raceway, means for supporting the elongate element with free sliding being arranged at the free end of the extension.
