CA 2450892

In this lift shaft door, a door panel (2,3) is composed of a respective front wall (4) and rear wall (5), which are connected together by thermally releasable connecting means (6), wherein at least a part of the closing edge of the respective door panel (2, 3) consists of a profile member (7, 8, 14) which is formed by the back wall (5) or thermally non-detachably fastened to this back wall (5). In the case of fire, the back wall (5) separates from the front wall (4) through release of the thermally releasable connecting means, wherein the front wall curves by heat effect whilst the back wall (5) with the closing edge retains the original shape. (Fig. 2)

L'invention concerne une porte de cage d'ascenseur dans laquelle un battant de porte (2, 3) est composé d'un panneau avant et d'un panneau arrière (4, 5) qui sont reliés l'un à l'autre par des moyens de liaison (6) détachables thermiquement. Au moins une partie de l'arête de fermeture du battant de porte concerné (2, 3) est constituée d'un profil (7, 8, 14) formé par le panneau arrière (5) ou fixé à ce panneau arrière (5) de manière non détachable thermiquement. En cas d'incendie, les moyens de liaison détachables thermiquement se défont de sorte que le panneau arrière (5) se sépare du panneau avant (4) et le panneau avant se cintre sous l'effet de la chaleur alors que le panneau arrière (5) pourvu de l'arête de fermeture conserve sa forme initiale.
