Abstract

A door assembly for a vehicle with two door leaves is stated. In each case the door leaves can be opened in such a manner that the maximum angle of opening between them can be limited. After a door leaf has been opened, the door leaves can thus only be pivoted together so that opening the first door leaf results in closing the second door leaf. As a result of this, access to a space in a vehicle may be controlled.

First claim

What is claimed is:

1. A door assembly for granting access to a space of a means of transport, comprising:
a first door leaf;
a second door leaf; and
a limitation device limiting a maximum angle of opening between the first door leaf and the second door leaf, irrespective of an angle of the second door leaf relative to a door frame,
wherein an angle of opening between the first door leaf and the second door leaf is adjustable, the first door leaf and the second door leaf are pivotally held relative to each other,
wherein in a closed state of the door assembly, the first door leaf can be opened by moving the first door leaf in a first direction while the second door leaf remains in a closed state,
wherein the first door leaf and the second door leaf can be jointly pivoted in a second direction opposite to the first direction until the first door leaf closes the door assembly,
wherein the second door leaf can be moved in the first direction to close the door assembly,
wherein, in the closed state of the door assembly, the second door leaf can be moved in the second direction while the first door leaf remains in the closed state,
wherein the first door leaf and the second door leaf can be jointly pivoted in the first direction so that the second door leaf closes the door assembly, and
wherein the first door leaf can be moved in the second direction to close the door assembly.

2. The door assembly of claim 1 , wherein the maximum angle of opening of the first door leaf relative to the second door leaf is about 60°.

3. The door assembly of claim 1 , wherein between the first door leaf and the second door leaf there is a damper in order to ensure closing of the first door leaf and of the second door leaf in a damped manner.

4. The door assembly of claim 1 , wherein at least one of the first door leaf and second door leaf comprises a protrusion in order to provide a passage area.

5. The door assembly of claim 1 , wherein the limitation device is removable.

6. The door assembly of claim 1 , further comprising:
at least one actuator;
wherein the actuator is arranged for opening at least one of the first door leaf and the second door leaf.

7. The door assembly of claim 1 , wherein the first door leaf and second door leaf form a security door.

8. The door assembly of claim 1 , wherein at least one of the first door leaf and second door leaf comprises a locking device operable both from a front of the respective at least one of the first door leaf and second door leaf, and from a rear of the respective at least one of the first door leaf and second door leaf.

9. The door assembly of claim 1 , wherein the first door leaf and the second door leaf are interconnected by means of a hinge.

10. A means of transport, comprising:
the door assembly of claim 1 for a space of the means of transport, including a first door leaf, a second door leaf, and a removable limitation device limiting a maximum angle of opening between the first door leaf and the second door leaf, irrespective of an angle of the second door leaf relative to a door frame,
wherein the first door leaf and the second door leaf are pivotally held relative to each other, an angle of opening between the first door leaf and the second door leaf is adjustable, the first door leaf opens against a direction a direction of passing through the door assembly and the first door leaf and the second door leaf are pivotable in the direction of passing through the door assembly so that the first door leaf closes the door assembly.

11. The means of transport of claim 10 , wherein the means of transport is an aircraft, and the space is the cockpit of the aircraft.

12. The means of transport of claim 11 , wherein at least one of the first door leaf and the second door leaf comprises at least one predetermined breaking point so that in the case of decompression in the cockpit or in a passenger space pressure equalization becomes possible.

13. The means of transport of claim 10 , wherein the maximum angle of opening of the first door leaf relative to the second door leaf is about 60°.

14. The means of transport of claim 10 , wherein between the first door leaf and the second door leaf there is a damper in order to ensure closing of the first door leaf and of the second door leaf in a damped manner.

15. The means of transport of claim 10 , wherein at least one of the first door leaf and second door leaf comprises a protrusion in order to provide an enlarged passage area.

16. The means of transport of claim 10 , wherein the door assembly is a security door assembly.

17. A method for providing access to a space of a means of transport with the use of the door assembly of claim 1 with a first door leaf and a second door leaf, starting from the state in which the first door leaf and the second door leaf are closed, comprising:
opening the first door leaf against the direction of passing through the door assembly the angle of opening between the first door leaf and the second door leaf being adjustable;
limiting a maximum angle of opening between
the first door leaf and the second door leaf with a limitation device, irrespective of an angle of the second door leaf relative to a door frame;
pivoting the first door leaf and the second door leaf in the direction of passing through the door assembly so that the first door leaf closes off a door passage; and
closing the second door leaf.

18. The method of claim 17 , further comprising:
unlocking the second door leaf,
wherein unlocking takes place after limiting the maximum angle of opening of the first door leaf relative to the second door leaf.

19. The method of claim 18 , further comprising:
locking the first door leaf relative to a position of the second door leaf; and
releasing the locking mechanism of the first door leaf,
wherein locking takes place after opening the first door leaf against the direction of passing through the door assembly and before pivoting the first door leaf and the second door leaf.

20. The method of claim 19 , wherein releasing the locking mechanism takes place after pivoting the first door leaf and the second door leaf and before closing the second door leaf.
