Definitions
- the invention relates to an anti-skid chain with a running net and a holding device connected to it, which in the assembled state is essentially closed to form a ring abutting an inner side flank of a tire, with one locking part being arranged at each end of the holding device, the two locking parts with one another are connectable, and the running net is tensioned on the outside of the tire by at least one tensioning / holding device.
- anti-skid chains with a holding device which can be connected to form a ring for a running network are the most likely to meet the requirement for quick and easy installation.
- the holding device lies against the inner flank of a tire.
- An anti-skid chain of the type mentioned is known for example from DE 199 47 855 AI.
- the known anti-skid chain has a holding device which can be connected to form a ring, for example a spring-elastic mounting bracket or a steel cable.
- the two ends of the holding device each have a closure part with which the holding device can be closed to form a ring.
- a first closure part has a hook and the second closure part has an opening which can be brought into engagement with the hooks.
- the second closure part is made of a hollow cylinder and has a hooking section for the hook part and a tubular fastening section with which it is fastened to the associated end of the holding device.

- One or more tensioning / holding devices can be provided for tensioning the running net LAU on the outside of the tire.
- the turnbuckles SP1, SP2 each have a tension cord SSI, SS2.
- a tension cord SSI, SS2 can be provided at its end arranged outside a tension lock SP1, SP2 with a hook HAK which can be attached to the running net LAU.
- the tension cord SSI, SS2 instead of the hook HAK has a receiving device for a hook and the hook is arranged on a chain strand of the running net LAU.
- the suspended tensioning strand SSI, SS2 can be partially pulled into the turnbuckle SP1, SP2 by actuating the turnbuckle SP1, SP2, whereby the running net can be tensioned.
- a possible embodiment for the turnbuckles SP1, SP2 is described for example in AT 408 635 B of the applicant.
- one of these turnbuckles SP1 is fixedly connected to a chain strand KE1 of the running network LAU and can be connected to a second chain rank KE2 for assembly with the hook HAK or via the tension strand SSI.
- each of the chain strands KE1, KE2 is connected to a closure part VE1, VE2 of the holding device HAL.
- the chain strands KE1, KE2 are in this case attached to end regions EN1, EN2 of the connecting parts VE1, VE2 in such a way that they fix the two closure parts VE1, VE2 against one another in a tensioned state (FIG. 5).
- the two end regions EN1, EN2 of the closure parts VE1, VE2 can be bent away from the respective base BAI, BA2 and a bore BOR for receiving a connecting element VER connected to the respective chain strand KE1, KE2, for example a hook exhibit.
- the closure parts VE1, VE2 according to FIG. 7 can be rotatably mounted about the longitudinal axis ⁇ of the holding device HAL, for example on each closure part VE1, VE2 an end region EN1 'assigned to an end section of the holding device can be bent around the respective end section EAL of the holding device HAL ,
