Abstract
Automatic opening and closing device for doors, applicable in elevators and lifts, characterized in that it consists of a motor and reducer equipment that provides the appropriate speed to a transmitter shaft to allow the rotation of a lever fixed to it by one of its ends, and limited in its total opening and closing travel respectively by a fixed stop and an elastic reopening element while at the other end protrudes perpendicularly a pin passing through which penetrates a bar on which it moves subject to it a slide that it is constituted by a vertical one being able to constitute said bar, according to the needs of assembly, in the axis-guide of lateral lateral roldanas or to be constituted by respective walls of rolling for a central pulley; said bar is rigidly fixed to the leaf or leaves of the door, forcing the lateral displacement of these along an upper guide, by means of two runners arranged in the upper part of the door, while on the other hand part said door terminates inferiorly in rolling elements that move along the lower guide that also allow its lateral movement along the same.
