Abstract

Structure de cage d'ascenseur (14) dans un immeuble, autour d'un ascenseur, permettant d'aider à se dégager d'une cabine d'ascenseur (76) en cas de panne de courant. Elle comprend une structure définissant une cage d'ascenseur (14) pour une cabine d'ascenseur (76), qui dispose d'un mur de cage arrière (24, 26) avec un escalier de secours (42, 42', 42'') se prolongeant à l'extérieur allant du mur arrière (24, 26) à un mur d'immeuble (12) permettant de se déplacer d'un étage à l'autre (50, 52, 54, 56) et, dans la cabine de l'ascenseur (76) d'une porte arrière (46) prévue pour se dégager de l'ascenseur en passant sur l'escalier de secours (42, 42' et 42'').
