Abstract

An access device enables controlled or secure communication between different areas of an enclosure, and in the example illustrated in the present application of an aircraft, while providing reduced size. The access device includes a folding door which, when in folded position, allows at least one of said openings to be closed and, when in deployed position, forms a security vestibule with at least one movable shutter allowing said opening created by the deployment of said folding door to be closed. By superimposing the main components of the security vestibule that said components allow to close, the device frees up the adjoining cabin space when the security vestibule is not in use.

First claim

1 . An access device enabling secure communication between at least two areas of an enclosure through at least one opening, the access device comprising:
a folding door which, when in a folded position, allows at least one of said openings to be closed and, when in a deployed position, forms a security vestibule with at least one movable shutter allowing said opening created by the deployment of said folding door to be closed.

2 . The access device as claimed in claim 1 , wherein the security vestibule is formed by the folding door, the movable shutter and partitions/walls between said areas of said enclosure against one of which one of the ends of the folding door is secured, as well as one of the doors at the level of said wall(s).

3 . The access device as claimed in claim 1 , wherein the folding door is a folding door with two leaves in the form of two solid panels rotatably hinged relative to one another and whose shape and identical dimensions are such that the panels overlap and fit together snugly in said opening so as to completely close said opening.

4 . The access device as claimed in claim 1 , wherein one of the longitudinal edges of said folding door is rotatably hinged at the one of the longitudinal edges of said opening that said folding door closes.

5 . The access device as claimed in claim 1 , wherein the movable shutter is placed against a partition separating two areas, moving in translation along the partition and has dimensions such that the movable shutter completely fills the opening in said partition to close it.

6 . The access device as claimed in claim 1 , wherein retaining, positioning and locking means are provided on the folding door and cooperate with corresponding means provided on the stationary structures of the enclosure to block the door in the closed folded position and in the deployed security vestibule position.

7 . The access device as claimed in claim 1 , wherein reinforcements are provided at the edges of the partition adjacent to the folding door to absorb a thickness of the folding door.

8 . The access device as claimed in claim 1 , wherein the partition adjacent to the folding door consists of two offset parts to absorb the thickness of the folding door. cm 9 . An aircraft comprising at least two areas and an access device enabling secure communication therebetween, the access device comprising:
a folding door which, when in a folded position, allows at least one of said openings to be closed and, when in a deployed position, forms a security vestibule with at least one movable shutter allowing said opening created by the deployment of said folding door to be closed.

10 . The aircraft as claimed in claim 9 wherein one of the two areas is the cockpit, another of the two areas is the cabin and the folding door closes the access between the cabin and cockpit.

11 . The aircraft as claimed in claim 9 , wherein another of the two areas are the toilet facilities and the deployed folding door rests on one of the walls of toilet facilities to form a security vestibule with said wall, the door of the toilet facilities, the partition and the shutter.

12 . An access control method for secure communication between at least two areas of an enclosure through at least one opening, in the method comprising:
deploying a folding door from a folded position in which the door closes at least one of said openings to a position wherein the door forms a security vestibule with at least one movable shutter allowing said opening created by the deployment of the door to be closed.
