(EN)A device in an unfoldable escape-ladder made of assembled rungs (1), the ends of which are attached between flexible lateral members (2), preferably steel wires, said rungs (1) being elongated and of plate-shaped material and capable to be stacked, the upper portion of the escape-ladder intended to be attached to a wall (4), a stay or the like, which escape-ladder in folded state having its rungs (1) lying stacked and each of the steel wires (2) forming a ring for each rung (1), which escape-ladder is provided with a means for releasing the ladder. According to the invention, each rung (1) has substantially S-shaped cross-section, where the free ends of the S-shaped portion (7) are extended so as to form two parallel legs (8, 9), and that the steel wires (2) are attached on the rang (1) with their substantial longitudinal direction perpendicular to said legs. In unfolded state of the ladder the upper one (8) of said legs constitutes a tread and the lower one (9) constitutes a distance member for maintaining the ladder at a certain distance from a wall or the like, along which the ladder is unfolded.

Dans l"etat deplie de l"echelle, la jambe superieure (8) constitue une marche et la jambe inferieure (9) constitue une piece d"ecartement, afin de maintenir l"echelle a une certaine distance du mur le long duquel l"echelle est depliee.
