Abstract

Echelle escamotable comprenant deux montants formés par des sections télescopiques (10), une pluralité d'échelons (11) montés chacun entre deux sections de montants respectifs et des mécanismes de verrouillage situés dans les échelons pour verrouiller automatiquement les sections (10) des montants l'une par rapport à l'autre quand elles sont en extension. Les mécanismes de verrouillage de chaque échelon sont conçus pour libérer les sections des montants reliées à l'échelon supérieur le plus proche quand celui-ci s'escamote contre l'échelon inférieur le plus proche.
