Abstract: A support structure for a lift car or elevator comprising two pairs of parallel rails and followers arranged in a horizontal parallelogram array between the lift car and support frame, such that compound movement of the followers on their respective rails allows the lift car to move in any horizontal direction to absorb transverse vibration due to misalignment of the vertical guide rails in the lift shaft. Also described are biassing devices arranged to lightly bias the lift car to a centralized horizontal position, and centralizing devices arranged to positively centralize the lift car for entry and egress at each floor.

Abstract: A lift car support apparatus providing relatively low natural frequencies of horizontal vibration of the car. A lift car is supported by a lift support member via suspension units. In each unit an intermediate member is pivotably connected to the lift support member. A single elongate member is fixedly connected to that intermediate member and pivotably connected to the underside of the lift car near its floor.

Abstract: A floor-levelling transducer for controlling stopping of an elevator car at a landing, comprising two pairs of electromagnetic core units mounted on the car to generate a signal indicative of the position of the car with respect to the landing, and two metal plates in the shaft corresponding to each landing position and cooperable with the core units to produce said signal, each of the metal plates being flat and in separate parallel planes extending longitudinally of the shaft and having tapering portions pointing in a direction opposite to that of the other plate.
