Abstract

L'invention est relative à un dispositif d'articulation destiné à équiper les échelles portables et particulièrement les échelles dites transformables. La caractéristique principale de l'invention réside dans le fait que l'un des échelons de l'échelle est utilisé comme axe d'articulation. Ce procédé permet de réaliser une articulation d'échelle transformable avec une seule pièce principale affectée à cette fin et autorise pour choix de l'axe de cette articulation chaque échelon de l'un des plans.
