Abstract: A towing device (1) for towing vehicles has a tow bar (8) movably mounted about at least two axes of rotation, and at least one mechanical drive (13) for moving the tow bar between an operating position and a position of rest. The drive has a mechanism (14) for generating an at least partially superimposed movement of the tow bar about both axes. The preferred features include the axes of rotation being positioned at right angles to each other. The mechanism is designed as a gear unit (21) coupling the pivot axis (16) and the axis of rotation (18). The rotational movement of the tow bar about the axis of rotation is derived from the pivoting movement of the tow bar or a housing (19).

Abstract: The hand brake lever 1 mounted rotatably at a stationary frame 4 engages with two lever arms 10 to a slide 11, which surrounds a tie rod 15 and is to displace same along its longitudinal axis via a silent ratchet. At least one cable line 6 is linked to the tie rod 15. The silent ratchet includes two clamping pieces 14 made of a plastic or other material, which are located between the side surfaces of the tie rod 15 and of the slide 11, which side surfaces face each other. The clamping pieces 14 are pressed via wedge surfaces 20, 21 against the tie rod 15, and opposite teeth 16, 19 lead to positive locking. The tie rod 15 is also subjected to the force of a tension spring 18 to bring about the absence of clearance.

Abstract: A multistep spindle drive is provided for converting a rotary movement into a linear movement with different speeds of withdrawal and extension. The spindle drive includes at least two threaded spindles, which telescopically mesh with each other and are in threaded connection with one another, and a nut. The inner threaded spindle is connected to a crank, and the nut is connected to a support wheel via a pipe. The internal threaded connection existing between the threaded spindles has a smaller diameter and a lower pitch than the external threaded connection existing between the outer threaded spindle and the nut. The speeds of withdrawal and extension are changed over based on the greater frictional force. A friction-increasing coupling member is arranged between the threaded spindles. The coupling member is spring-loaded and can be set for changing the friction.
