Abstract

La présente invention concerne une échelle (1) comprenant au moins deux montants (2) d'échelle qui courent dans le sens longitudinal de cette échelle (1). Cette échelle (1) comprend une plaque (6) fixée sur sa partie supérieure et on peut augmenter la taille de cette plaque dans une direction parallèle aux échelons (3) par un déploiement ou par une extension, cette plaque étant connectée de façon pivotante à l'échelle. Le déploiement des parties (8) de la plaque sur cette plaque ou la mise en place d'une prise entre un ascenseur et une paroi de puits d'ascenseur permet d'assurer cette échelle dans une position fixe à l'intérieur d'un ascenseur, de façon que cette échelle ne puisse pas glisser et que les portes de l'ascenseur ne puissent pas se fermer.
