Abstract
The emergency-opening sliding door comprises at least one door-leaf constituted by a panel which is stationarily fixed with respect to a panel frame attached to the door casing and at least one movable panel coupled to the frame by means of a roller track which permits displacement of the movable panel in sliding motion in a direction parallel to the fixed panel. The door is provided with an articulation system for permitting a movement of rotation of at least one of the panels about a vertical axis. The driving means for displacement in sliding motion are secured to the panel frame so as to be driven together with the frame in its movement of rotation.
