Embodiment Construction

[0053] The ladder according to the invention and shown in the accompanying drawings comprises: a single column 1 , a rung 2 and two support arms 3 , said rungs 2 and said support arms 3 being hinged on said single column 1 .

[0054] The monocolumns 1 , the crosspieces 2 and the support arms 3 are made of tubes of quadrangular, in particular square cross-section, for example made of aluminium.

[0055] The monocolumn 1 is substantially rectilinear except in its upper part 1S which is angularly arcuate with respect to the remaining rectilinear part of said monocolumn. At the free end of this single post, said curved upper part 1S supports hook means 4 (eg double hooks).

[0056] The crosspieces 2 are distributed along the single column 1 in an alternate arrangement on both sides of the single column. Each of the transoms is hinged on said single column 1 by its inner end 2I about an eccentric axis 5 orthogonal to said single column 1 .

[0057] Therefore, rung 2 can take:

Abstract

The invention relates to a ladder comprising a single post (1) provided with a fixing means (4) on the upper end (1S) thereof, said ladder comprising an anchoring means (9, 10) which is especially adapted to said fixing means (4) and is attached to the wall (7), and foldable supporting arms (3) which are connected to either side of the single post (1) in an articulated manner.

Description

technical field [0001] The invention relates to a ladder system which can be used on a vehicle, in particular a civil aircraft, for climbing over a wall belonging to said vehicle. Background technique [0002] It will be readily understood that the movement of the vehicle necessitates that the ladder used be held securely against said wall while it is in use. Furthermore, due to the lack of space available on the vehicle, the ladder must be collapsible so as to have a minimum space requirement when it is not in use. [0003] For example, document US-A-2924291 already discloses a ladder for a ship comprising: [0004] - means for hooking the wall of said ship; [0005] - a single column, on its upper part equipped with said hook device; [0006] - transoms provided on said monocolumn on both sides thereof, said transoms being hinged on said monocolumn by the pivot of the monocolumn around which their inner ends surround, so that said transoms can Take two extreme position...
