Abstract
L'invention concerne une échelle pliable qui possède une première partie d'échelle et une seconde partie d'échelle fixée de manière articulée sur la première partie d'échelle à l'aide d'une paire de mécanismes à charnières. Chaque mécanisme à charnières est adapté pour bloquer la première et la seconde partie d'échelle de sorte que la première partie d'échelle et la seconde partie d'échelle forment un angle entre elles. Le mécanisme à charnières possède un mécanisme de déplacement et un sélecteur d'angle d'échelle, reliés audit mécanisme à charnières, afin de pouvoir choisir manuellement l'angle entre la première et la seconde partie d'échelle, et une goupille de verrouillage destinée à verrouiller la première et la seconde partie d'échelle dans une position angulaire.
