ABSTRACT:
A guide device for guiding an elevator during its ascending and descending movement features a pair of guide rails disposed on opposite sides of the elevator body in parallel relation with the vertical line of movement of the elevator body and spaced apart to provide a gap between the sides of the elevator body and the guide rails, a plurality of guides carried by the elevator body and being interlocked with the guide rails on both sides of the elevator body to guide the vertical movement of the elevator body along the guide rails, and the guides being slidably disposed on the elevator body and spring biased in the direction of the guide rails so as to maintain the guides in interlocked relation with the guide rails in their normal state and to project the guide further in the corresponding direction of one of the guide rails when the elevator is shifted accidentally to one side to bend the other guide rail, upon collision therewith, and thus prevent derailment of the elevator from the guide rails.
