ABSTRACT:
The device disclosed serves to control the opening and shutting movement of sliding elevator doors, and is designed to lock the compartment door (3) and the landing door (5) together when positioned face to face, in such a way that both doors open and shut as one. Such a device comprises a projecting catch fitted to the landing door (5), and a mechanism carried by the compartment door (3), which engages the catch and grips it between the upright surfaces of a pair of jaws (9, 10) that can be drawn together and spread apart within a horizontal plane, as well as being traversed horizontally at right angles to the landing door toward and away from the catch.
