Abstract:
A relocation device comprising a rack and at least one carriage moveably disposed thereon, the at least one carriage having a drive unit, wherein the drive unit has a toothed drive wheel operably engaged to a motor, a deflector, a closed toothed belt, and a pressure device having a first pressure surface and a second pressure surface, wherein the distance between the first and the second pressure surfaces is greater than the individual inner diameter of at least one of the toothed drive wheel and the deflector, and wherein the toothed belt is elastically stretchable and has an inner toothed surface and an outer toothed surface, said inner toothed surface operably engaging the toothed drive wheel and the deflector, and the outer toothed surface of the toothed belt operably engaging the rack, and wherein the pressure device is moveably disposed to convert a tension force produced in the elastically stretchable toothed belts by mounting it in an elastically stretched state into a pressure directed onto the inner surface of the toothed belt and in the direction of the rack, wherein the first pressure surface is disposed to direct a pressure onto the inner surface of the toothed belt in the direction of the rack and wherein the second pressure surface is disposed to receive a pressure from the elastically stretched toothed belt and direct said pressure to the first pressure surface and in a direction of the rack.
