Abstract

Échelle à perches avec mécanisme amélioré comprenant une série de montants, d'éléments d'articulation, un mécanisme de blocage et des échelons transversaux, où chaque montant consiste en un échelon creux dont le calibre diminue alors la hauteur de son emplacement augmente. L'échelon supérieur et l'échelon inférieur peuvent être raccordés, s'ajustent entre eux et sont dotés de nécessaires de raccordement horizontaux à l'extrémité supérieure desdits échelons. La partie intérieure dudit nécessaire de raccordement comporte un mécanisme de blocage afin de s'emboîter par pression dans un orifice de passage dudit échelon afin de fixer la perche entre chaque échelon, et l'extérieur dudit mécanisme de blocage est recouvert par la traverse. Grâce au mécanisme de blocage amélioré, l'échelle à perches peut être assemblée facilement et fermement afin d'assurer une sécurité supérieure pour les utilisateurs, même lorsqu'une force extérieure est appliquée.
