Tensioning device for e.g. snow chain, has blocking pawl engaged with ramp surfaces in gear ring in end positions, where ramp surfaces arranged in different positions support sprockets of ring to stop movement of ring in sprocket direction

摘要

The device has a blocking pawl moved between two end positions corresponding to blocking positions by an actuating member. The blocking pawl is engaged with ramp surfaces in a gear ring in the end positions. The ramp surfaces support sprockets of the gear ring to stop the movement of the gear ring in a sprocket direction. The ramp surfaces are arranged in different positions to cooperate with the sprockets of different orientations. The actuating member has a tensioning strand moved in a housing in the blocking positions.
