Abstract

A system and method for protecting an aircraft staircase having a plurality of steps positioned between two sides comprises a step cover configured to be removably coupled to the plurality of steps, a first side cover configured to drape over and be removably coupled to a first one of the sides, and a second side cover configured to drape over and be removably coupled to a second one of the sides, the step cover, the first side cover and the second side cover comprising a lightweight, flexible material. A hood is removably coupled to the first and second side covers or to the staircase to cover and temporarily block access to the staircase.

First claim

I claim:

1. A system for protecting an aircraft staircase having a plurality of steps positioned between two sides, the system comprising:
a step cover configured to be removably coupled to a top landing surface of each of the plurality of steps;
a first side cover configured to drape over a first one of the sides and be removably coupled to the step cover;
a second side cover configured to drape over a second one of the sides and be removably coupled to the step cover; and
a hood configured to be removably coupled to the first side cover and the second side cover to cover the staircase; the hood, the step cover, the first side cover and the second side cover comprising a flexible material.

2. The system of claim 1 , wherein the step cover, the first side cover, the second side cover and the hood comprise one or more fasteners coupled thereto and configured to facilitate removable coupling of the step cover and the hood to the first side cover and the second side cover.

3. The system of claim 1 , wherein the step cover has a width substantially equal to a width of the plurality of steps and a total length substantially equal to a sum of a length and a rise of all of the plurality of steps in the staircase.

4. The system of claim 3 , wherein the step cover comprises score lines extending across the width of the step cover and spaced apart in a lengthwise direction of the step cover by distances equal to the length and the rise of the plurality of steps.

5. The system of claim 3 , wherein the length of each step in the step cover represents a step cover landing surface, the system further comprising a non-skid material positioned on the step cover landing surface.

6. The system of claim 5 , wherein the non-skid material has a width equal to the width of the plurality of steps and a length equal to at least a part of the length of the plurality of steps.

7. The system of claim 1 , wherein the first side cover is configured to encapsulate the first one of the sides and the second side cover is configured to encapsulate the second one of the sides.

8. The system of claim 1 , wherein the first side cover and the second side cover comprise two pieces of the flexible material joined together along one edge to form a top edge of the first side cover and the second side cover and a padding material positioned on an interior surface of each of the two pieces.

9. The system of claim 1 , wherein the hood comprises hook-and-loop fasteners positioned proximate edges of the hood for removable coupling to hook-and-loop fasteners positioned along a top edge of the first side cover and the second side cover.

10. A method of protecting an aircraft staircase having a plurality of steps positioned between two sides, the method comprising:
removably coupling a flexible step cover to a top landing surface of each of the plurality of steps;
draping a flexible first side cover over a first one of the sides and removably coupling the first side cover to the flexible step cover;
draping a flexible second side cover over a second one of the sides and removably coupling the second side cover to the flexible step cover; and
draping a hood over the staircase and removably coupling the hood to the first side cover and the second side cover.

11. The method of claim 10 , further comprising configuring the flexible step cover to have a width substantially equal to a width of the steps and a total length substantially equal to the sum of a length and a rise of all of the steps in the staircase.

12. The method of claim 11 , further comprising configuring the step cover to have score lines extending across the width of the step cover and spaced apart in the lengthwise direction of the step cover by distances alternatively equal to the length and the rise of steps, and folding the step cover along the score lines to form alternating step sections and rise sections.

13. The method of claim 12 , further comprising positioning a non-skid material on the step sections.

14. The method of claim 13 , further comprising configuring the non-skid material to have a width equal to the width of the steps and a length equal to at least a part of the length of the steps.

15. The method of claim 10 , wherein draping the first side cover comprises encapsulating the first one of the sides and draping the second side cover comprises encapsulating the second one of the sides.

16. A method of protecting an aircraft staircase having a plurality of steps positioned between two sides, the sides having a handrail positioned on a top portion of the sides, the method comprising draping a hood over the staircase and removably coupling the hood around the handrail on the sides and fastening the hood to itself to temporarily block access to the staircase.
