Abstract

Improved interlocking device for elevator doors of elevator shafts, of the type that on each floor comprises a hook pin provided with a locking roller rotatably connected to the sliding door of the elevator shaft, whose pin can adopt a locking position in which it engages at the end of an interlocking rail and that for unlocking can be rotated to remove it from the locking position and is movable along the rail together with the doors of the elevator shaft and the car that are opened by means of of a driver attached to the door of the cabin and which, by means of driving rollers, attacks the hook pin, essentially characterized by the fact that at the end of the locking rail subjected to the end of the opening path of the door there is a cam-like control that returns the hook pin to an angular position corresponding to the latching position with the closed door, whose cam leads to the locking roller to a position of engagement of said roller, the driving rollers and the lock being located with their axis parallel to the axis of rotation of the hook pin, and the axes of said rollers being in parallel planes they are cut with the axis of rotation of the hook pin, whose rollers the internal driver is located at a shorter distance, while the external one is at a greater distance, from said axis of rotation, in whose device the roller of locking in the the locking position makes contact with a substantially vertical surface of the end of the locking rail opposite the cam-type control, from which the locking surface is withdrawn, being raised up to the running surface of said rail upon the introduction of the driver, constituted by a plate, for between the driving rollers, of which the internal receives the translational force or thrust of said plate, whose the force acts in the direction of the opening of the door, while the external roller receives the torsional moment thus produced and limits the subsequent turning movement of the hook pin.
