Abstract

L'invention concerne une échelle comportant des montants (1, 2) dont au moins un (1) peut être modifié en longueur à l'aide d'un dispositif de prolongation pour adapter l'échelle à des surfaces de pose obliques. L'échelle comprend en outre un dispositif d'ajustement et un nombre de passages, de cavités ou d'évidements formés dans ladite échelle. Un élément de blocage (5) muni d'un élément d'actionnement est guidé à travers le montant (1) et peut être introduit de manière facultative par sa première extrémité éloignée de l'élément d'actionnement, dans les passages, cavités ou évidements et en être ressorti. L'élément de blocage (5) est également guidé à travers un autre montant (2) qui comporte quant à lui l'élément d'actionnement qui s'appuie sur lui et coopère avec la seconde extrémité de blocage.
