Abstract

A door for a storage compartment of an aircraft includes a door leaf and a profiled strip connected to an edge of the door leaf. The profiled strip includes openings that provide a path for gas exchange such that smoke from the storage compartment is detectable outside of the storage compartment by passing the profiled strip.

First claim

The invention claimed is:

1. A door for a storage compartment of an aircraft, comprising:
a door leaf; and
a profiled strip connected to an edge of the door leaf;
wherein the profiled strip comprises a first plurality of openings providing a path for gas exchange such that smoke from the storage compartment is detectable outside of the storage compartment by passing the profiled strip,
a hinge for attaching the door leaf to a door frame;
wherein the profiled strip interconnects the hinge and the door leaf;
wherein the profiled strip further comprises:
a first side wall for attaching the hinge;
a second side wall for attaching the door leaf;
a front wall interconnecting the first side wall and the second side wall;

wherein the first plurality of openings is provided in the front wall.

2. The door of claim 1 , wherein the first plurality of openings comprises a plurality of longitudinal openings arranged in a row parallel to the edge of the door leaf.

3. The door of claim 1 , wherein the first plurality of openings are provided along the complete profiled strip.

4. The door of claim 1 , wherein the profiled strip further comprises:
a back wall interconnecting the first side wall and the second side wall of the profiled strip;
wherein a second plurality of openings is provided in the back wall.

5. The door of claim 1 , wherein at least one of the front wall and a back wall comprises two rows of openings.

6. The door of claim 1 , wherein the profiled strip further comprises: an intermediate wall interconnecting the front wall and a back wall.

7. The door of claim 1 , wherein at least one of the front wall and a back wall comprises a deepened middle part comprising at least some of the first or second plurality of openings.

8. The door of claim 1 , wherein the front wall comprises a T-shaped part extending over the first plurality of openings in the front wall.

9. The door of claim 8 , wherein a surface of the T-shaped part is flush with a surface part of the front wall attached to the side walls.

10. The door of claim 1 , wherein the profiled strip provides an edge protection profile for the door leaf having a same profile as an edge protection profile surrounding the door leaf at other edges of the door leaf.

11. The door of claim 10 , wherein the edge protection profile has a U-formed shape.

12. The door of claim 1 , wherein the profiled strip is made from aluminum.

13. A profiled strip for a door comprising a door leaf and a hinge for attaching the door leaf to a door frame in an aircraft, wherein the profiled strip comprises first and second side walls, a front wall and a back wall;
wherein the front wall and the back wall have a first and a second pluralities of openings providing a path for gas exchange through the profiled strip, such that smoke can pass the profiled strip
wherein the profiled strip interconnects the hinge and the door leaf;
wherein the profiled strip further comprises:
a first side wall for attaching the hinge;
a second side wall for attaching the door leaf;
a front wall interconnecting the first side wall and the second side wall;

wherein the first plurality of openings is provided in the front wall.

14. A method for indicating smoke behind a door comprising a door leaf and a hinge for attaching the door leaf to a door frame in an aircraft, the method comprising:
providing the door with a profiled strip comprising first and second side walls, a front wall and a back wall, wherein the front wall and the back wall have a first and a second pluralities of openings providing a path for gas exchange through the profiled strip, such that smoke can pass the profiled strip;
interconnecting the hinge and the door leaf by the profiled strip; and
using the profiled strip as a smoke indication device,
wherein the profiled strip further comprises:
a first side wall for attaching the hinge;
a second side wall for attaching the door leaf;
a front wall interconnecting the first side wall and the second side wall;

wherein the first plurality of openings is provided in the front wall.
