Abstract

PROBLEM TO BE SOLVED: To improve the function of an emergency exit for a shutter curtain by attracting a door body made of the same fire-resistive sheet as the curtain to the emergency exit by a bonded magnet. SOLUTION: The upper end section of a door body 3 consisting of the same fire-resistive sheet as a shutter curtain 1 is sewn at the upper end part of an emergency exit 2 bored at the lower end part of the curtain 1, and the door body 3 is installed the emergency exit 2 in a freely open-close manner. Bonded magnets 7, 11 are mounted at the left-right edge parts 4, 5 and lower edge section 6 of the emergency exit 2 and bag sections set up at the left-right edge parts 8, 9 and lower edge section 10 of the door body 3 by housing, etc., respectively, and the emergency exit 2 is closed by the door body 3 by the attraction of the bonded magnets. Fire-resistive Velcroes are juxtaposed near the magnets 7, 11, and the opening of the emergency exit 2 is prevented even when the attractive force of the magnets 7, 11 is lowered at a high temperature. Accordingly, the emergency exit is opened and a man can escape even when the man fails to escape while smoke and a flame can be interrupted because no clearance is formed in the emergency exit even when the shutter curtain is deflected by hot air.
