Abstract

The invention relates to an aeroplane comprising several decks which are arranged above each other, for passengers, freight and/or crew members, also comprising at least one staircase connected to the decks. Said aeroplane is characterized in that the staircase is provided with photoluminescent markings which enable the staircase to be recognized easily, even in poor lighting conditions, whereby orientation of passengers and crew members to exit is made easier in the event of an emergency.

Claims

1. In an airplane having a plurality of decks, arranged one on top of the other, and at least one staircase, which connects the decks, a first set of photoluminescent strip-like markers arranged on both sides of the staircase steps at the lateral ends thereof, and a second set of photoluminescent strip-like markers which can be seen from above and are essentially uninterrupted, arranged at the sides of the steps, following the ascent of the staircase.

2. In the airplane as claimed in claim 1, wherein the staircase has a landing, and photoluminescent markers are provided in the region of the landing.

3. In the airplane as claimed in claim 1, wherein the markers have different colors.

4. In the airplane as claimed in claim 1, wherein the markers have indicators selected from the group consisting of arrows, symbols and writing.

5. In the airplane as claimed in claim 2, wherein the markers have different colors.

6. In the airplane as claimed in claim 2, wherein the markers have indicators selected from the group consisting of arrows, symbols and writing.

7. In the airplane as claimed in claim 3, wherein the markers have indicators selected from the group consisting of arrows, symbols and writing.

8. In the airplane as claimed in claim 5, characterized in that the markers have indicators selected from the group consisting of arrows, symbols and writing.

9. In the airplane as claimed in claim 1, wherein the markers have different luminosity.

10. In the airplane as claimed in claim 2, wherein the markers have different luminosity.

11. In the airplane as claimed in claim 9, wherein the markers have indicators selected from the group consisting of arrows, symbols and writing.

12. In the airplane as claimed in claim 10, wherein the markers have indicators selected from the group consisting of arrows, symbols and writing.

13. In the airplane as claimed in claim 3, wherein markers having different luminosity are used.

14. In the airplane as claimed in claim 5, wherein markers having different luminosity are used.

15. In an airplane having a plurality of decks, arranged one on top of the other, and at least one staircase, which connects the decks, said staircase including a pair of opposed side walls and steps extending there between, photoluminescent strip-like markers arranged on both sides of the staircase steps at the lateral ends thereof, and photoluminescent strip-like markers descending down said staircase and forming an angle with said markers on said stairs, said markers descending down said staircase being on said side wall.

16. In an airplane as claimed in claim 15, wherein there are two opposed sets of markers descending down said staircase, one on each side wall.

17. In the airplane as claimed in claim 16, wherein said descending markers are on said top of each side of said side wall.

18. In the airplane as claimed in claim 15, wherein said descending markers descend in a straight line.
