SNOW CHAIN

摘要

The object of the invention is to provide a snow chain which can be mounted in one step, which therefore does not need to be subsequently tightened. The snow chain (1) is mounted on L-shaped straps (2,3) which are rotatably mounted on a baseplate (16). By fanning out the straps (2, 3), the snow chain is moved into the position illustrated in Fig. 1 on the wheel (4) standing on the floor. Subsequently, the spring device provided according to the invention is tightened, as a result of which the straps (2) are pretensioned with respect to one another in the direction of the arrow (5). The chain is automatically tightened by the spring device when the vehicle drives off. The spring device consists preferably of a displaceable bar (12) to which two pulling springs (7) are attached. The other ends of the pulling springs are connected to the straps (2) by means of cables (15) which are guided over deflection rollers (8).
