Abstract

In a door (1) for a compartment incorporating moving part(s), having a safety device (5) with a double locking point (6-1, 6-2) activated by two control levers (7-1, 7-2), each having a bolt (8) (dis)engaging a hook (9), and a controlled opening blocker (10), the trajectories of the levers overlap, so that the first lever (7-1) forms an obstacle for the second during unlocking. The blocker is a single lock for immobilizing the locked first lever. A door (1) for closing a compartment incorporating moving part(s) comprises a panel (2) hinged (3) to a frame (3) and having a safety device (5) with a double locking point (6-1, 6-2) activated by two control levers (7-1, 7-2), each having a bolt (8) which engages with a hook (9) (in locked position) or is disengaged by rotating the lever. The safety device also has a controlled blocker (10) for preventing opening of the door, at least when the moving part is operating. The novel features are that (a) the opening and closing trajectories of the two levers at least partially overlap, such that in the locked position the first lever (7-1) forms an obstacle for the second lever (7-2) during unlocking of the safety device and (b) the controlled blocker consists of a single lock for immobilizing the first lever in the locked position.
