Abstract

A separating element for a platform cabin is provided. The separating element comprises: at least one stationary partition, delimiting a passage defining a circulation axis inside the cabin; at least one leaf, mounted transversely movable relative to the circulation axis between a closed position, in which it extends through the passage, and an open position, in which it is positioned at least partially spaced away from the passage; and means for moving the or each leaf between the closed position and the open position thereof, the or each leaf being adapted to move along the plane transverse to the circulation axis.

First claim

The invention claimed is:

1. An aircraft cabin comprising at least one separating element, said separating element including:
at least one stationary partition, delimiting a passage defining a circulation axis inside the cabin;
at least one leaf, mounted transversely movable relative to the circulation axis between a closed position, in which it extends through the passage, and an open position, in which it is positioned at least partially spaced away from the passage, the or each leaf comprising at least one leaf portion; and
a movement system for moving the or each leaf between the closed position and the open position thereof, the or each leaf being adapted to move along the plane transverse to the circulation axis, wherein the movement system comprises, for the or each leaf, a movement mechanism for moving a driven leaf portion of the at least one leaf portion of the leaf, the movement mechanism comprising two push rods each articulated, by a first point of articulation, to a respective stationary partition among the at least one stationary partition, and by a second point of articulation to a connecting element which is fixed relatively to the driven leaf portion, the first points of articulation being spaced apart from one another, the push rods being substantially parallel to one another and being adapted to remain substantially parallel during the movement of the leaf from the open position to the closed position thereof.

2. The aircraft cabin according to claim 1 , wherein the points of articulation form the four apices of a parallelogram irrespective of the position of the leaf.

3. The aircraft cabin according to claim 1 , wherein the separating element comprises, for the or each leaf, a limiting member for limiting the travel of the leaf along the circulation axis, said limiting member having at least one protrusion secured to one of the push rods and adapted to bear against the respective stationary partition.

4. The aircraft cabin according to claim 1 , wherein the respective stationary partition has two partition panels delimiting a space between them for receiving the leaf when it is in the open position, and the separating element has, for the or each leaf, a limiting member for limiting the travel of the leaf along the circulation axis, said limiting member having at least two extensions, each secured to one of the partition panels, and at least two skates secured to the driven leaf portion of the leaf, each skate being adapted to be sandwiched between one of said extensions and the driven leaf portion when the leaf is in the closed position.

5. The aircraft cabin according to claim 1 , wherein the separating element comprises, for the or each leaf, a limiting member for limiting the travel of the leaf along the circulation axis, said limiting member including a fastening member jointly movable with the movement mechanism and a slide for receiving the fastening member, formed in the respective stationary partition, the fastening member cooperating with the slide between an intermediate position of the leaf and the closed position to prevent the leaf from moving away from the respective stationary partition when the leaf is in the closed position.

6. The aircraft cabin according to claim 5 , wherein the fastening member is pivotably mounted on the movement mechanism between an idle position, in which is retracted substantially in a plane defined by the movement mechanism, and a position retaining the leaf, in which it is deployed substantially perpendicular to said plane.

7. The aircraft cabin according to claim 1 , wherein the connecting element comprises an adjustment system for adjusting the position of the leaf relative to the movement mechanism along two axes comprised in the transverse plane.

8. The aircraft cabin according to claim 7 , wherein the adjustment system includes a support secured to one of the movement mechanism and the driven leaf portion, a flange secured to the other of the driven leaf portion and the movement mechanism, and at least one cam lock, the or each cam lock having a larger cylinder portion and a smaller cylinder portion that is off-center relative to the larger cylinder portion, the flange having at least one opening in which the larger cylinder portion is received, said opening having a shape substantially complementary to the shape of a radial section of the larger cylinder portion, and the support having at least one elongate slot in which the smaller cylinder portion is received, said slot having a width smaller than the diameter of the opening, so that, when the cam lock is pivoted along an axis which is coaxial with the larger cylinder portion, the smaller cylinder portion is moved perpendicular to the direction of elongation of the slot, thus causing movement of the support relatively to the flange.

9. The aircraft cabin according to claim 1 , wherein the at least one stationary partition comprises a first stationary partition and a second stationary partition opposite the first stationary partition, the passage being delimited between the first and second stationary partitions.

10. The aircraft cabin according to claim 9 , wherein the at least one leaf comprises two opposite leaves.

11. The aircraft cabin according to claim 1 , wherein the separating element comprises, for the or each leaf, a locking system for locking the leaf in the open position and in the closed position, the locking system having a movable locking member secured to the leaf and two stationary locking members secured to the respective stationary partition, one of the stationary locking members cooperating with the movable locking member to lock the leaf in the open position, and the other one of the stationary locking members cooperating with the movable locking member to lock the leaf in the closed position.

12. The aircraft cabin according to claim 3 , wherein the protrusion comprises a rolling member.
