Abstract (en)
[origin: WO8302234A1] Closure device for fire protection by automatic obturation of existing openings (10); the invention is preferably intended to chambers connected by transport rails (12). The device forms a self-contained constructive unit and comprises essentially the simultaneous utilization of a bolt (18) displaceable (17) in parallel to the fire section separation (11), with an inner cutting (31), and a hinged door (22) capable of rotating by 90 to 180<o> about a rotation point (20) of which the longitudinal axis (19) is displaced in parallel to the fire section partition (11) as well as to the joined action obtained by construction.
