摘要

An electro-mechanical maneuvering and safety equipment for automatic doors of the cabin and landing of elevators, characterized by the incorporation of an electric motor, which consists of a running inverter and controlled by the floor relays and the inverters of the control circuit, getting stuck said motor at the appropriate height of a support plate, in turn, secured to the chassis of the car in question; a fixed pole on the motor shaft; a reduction pulley that communicates of the rotation of the poleºn of the motor with the aid of a belt of transmission and has coupled in its own axis a pinion; a carrier pulley diametrically of a lever arm, as well as conditioned in its upper contour of a toothing intended to mesh with that of the pinion of the reduction pulley in a rotation between 150 and 180º in each of the alternate movements of the engine, while which suitably located in the lower periphery a cam on purpose to operate, alternatively and at predetermined times, the microswitches stop the end of the processes of opening and closing of the doors of cabin, in addition to the intermediate microswitch of speed change of the engine to more reduced that avoids the abruptness of stop; a connecting rod articulated by a protruding end of the adjacent end of the diametral lever of the semi-sheared pulley with the purpose of transforming the rotation of said lever-pulley in horizontal and reciprocating movements of back and forward, while the other end of the rod itself it is fixed to the hanger of the matrix sheet of the cabins, so that it attracts or impels it in the alternate movements of opening and closing, in whose movements, the aforementioned matrix sheet simultaneously moves its turn to the other cabin sheet with help of tensile cables guided horizontally on pulleys of the ends of the plate-support to the pair that hooked on both sheets inversely according to the directions of separation and approach of the said alternate movements of opening and closing, carrying fixed in the respective hangers of both leaves of cabin, matrix and driven, separate handles in u, without prejudice still to be slidable in their displacements so guide rails of the lower edge of the repeated plate-support, as well as with the competition of nylon rollers, above, of adjustable eccentrics to annul vibrations, below, sliding blocks through the guide channel of the support tread of the floor of the cabin, and shock absorbers fixed vertically on the adjacent edges of the sheets themselves.
