Abstract

Articulation pour échelles pliantes composée d'une part d'un système de verrouillage et d autre part d'un ou deux flasques extérieurs formant une demi-articulation solidaire d'un élément constitutif du montant de l'échelle et d'un flasque intérieur formant l'autre demi-articulation également solidaire d'un autre élément constitutif du montant de l'échelle caractérisé en ce que l'un ou les deux flasques extérieurs comportent plusieurs évidements alors que le flasque intérieur n'en comporte qu'un seul. Cette disposition desdits évidement permet à la fois une pré-sélection et une automaticité du point de verrouillage de l'articulation correspondant à la position opérationnelle désirée de l'échelle pliante.
