Abstract

L'invention concerne un dispositif de fermeture pour la protection contre le feu par l'obturation automatique des ouvertures existantes (10); elle est destinée de préférence aux chambres reliées par des rails de transport (12). Le dispositif forme une unité constructive indépendante et consiste, pour l'essentiel dans l'emploi simultané du principe d'un verrou (18) déplaçable (17) parallèlement à la séparation d'une section d'incendie (11), avec une coupure intérieure (31), et une porte articulée (22), apte à tourner de 90 à 180o autour d'un point de rotation (20) dont l'axe longitudinal (19) se déplace parallèlement à la séparation de la section d'incendie (11), ainsi qu'à leur action conjointe obtenue par construction.
