Abstract

Un stabilisateur d'échelle pour montage sur au moins un montant d'une échelle à barreaux creux comprend un élément d'extension de montant allongé, une barre transversale dimensionnée pour montage sur un axe de pivotement au travers d'un barreau creux de l'échelle. Une goupille de verrouillage s'étend de la barre transversale par une ouverture d'un réseau d'ouvertures dans l'élément d'extension et coopère avec une barre de verrouillage. La barre de verrouillage est raisonnablement montée sur la goupille de verrouillage pour verrouiller l'élément d'extension de montant sur le montant.
