Abstract

Improvements in the construction of folding staircases, characterized in that it is composed of two uprights of advantageously angled profile, arranged one opposite the other so that it is opposed by its internal faces, of which the perpendicular to the plane of the staircase carry, respectively placed towards the edge of the wing of the first pillar and towards the angle of the second, two longitudinal ribs that each face a rib of the other pillar and provided, at regular intervals in the longitudinal direction, with opposite perforations receiving pivots for the articulation of the steps, so that it can be folded by approaching the uprights, because it has a railing perpendicular to the plane of the staircase and which also consists of two uprights, one of which is integral with one of the uprights of the staircase, joined by tie rods equally articulated in their end portions on pivots fitted in said s stiles, which can be completed by a railing, similar to the first, which is deployed parallel to the plane of the ladder, which may have additional uprights, equally braced or bearing rungs, articulated in head on the other uprights, so as to allow the constitution of either a footstool or a double staircase, and by means of fixing means of fixing one of the uprights of the ladder, and possibly the second handrail, on a support, means of maintenance in retracted position and in the unfolded position of the ladder, as well as means of acoustic and/or luminous signaling in case of deployment.
