The electromechanical device, controlled by a central electronic unit (60), includes a base (10), a sled (12) supported and guided by a relevant device (11) associated with the base (10), which acts by means of a stem (13) and a connecting element (4) on door (2), which can turn around its own hinge (R) axle. A set of limit switches (41 and 42) cooperates with corresponding checkings (39 and 40) fitted on the above nearly-closing of the door (2). A motor (20), by means of a reducer (15) as well as of a gear whell (18), starts the sledge (12) while another motor (25) accomplishes the coupling and uncoupling of the gear wheel (18) with rack (9). |
