Abstract

A runway guidance sign includes a housing defining an interior space and an opening at a front side. The housing includes opposite upper and lower walls. An interior upright is received in the interior space of the housing. The interior upright is fastened to and extends between the upper and lower walls. The interior upright is integrally formed from a one-piece sheet of material.

First claim

What is claimed is:

1. A runway guidance sign comprising:
a housing defining an interior space and an opening at a front side, the housing includes opposite upper and lower walls; and
an interior upright received in the interior space of the housing, the interior upright fastened to and extending between the upper and lower walls, wherein the interior upright is integrally formed from a one-piece sheet of material, and wherein the interior upright comprises a body having opposite planar side faces and opposite front and rear ends, the side faces being free of openings extending therethrough, wherein the interior upright includes a vertical body having first and second halves folded over one another about a fold line; and
recesses in the front and rear ends of the body to provide clearance for structures within the interior space of the housing.

2. The runway guidance sign set forth in claim 1 , further comprising a rear wall and a runway guidance sign panel opposing the rear wall and secured to the housing at the front side to enclose the interior space.

3. The runway guidance sign set forth in claim 2 , wherein the interior upright is disposed between the rear wall and the runway guidance sign panel.

4. The runway guidance sign set forth in claim 1 , wherein the first and second halves are mirror images of one another.

5. The runway guidance sign set forth in claim 1 , wherein the interior upright includes a generally planar vertical body, and upper and lower fastening tabs extending outward out of plane from upper and lower ends of the generally planar vertical body.

6. The runway guidance sign set forth in claim 5 , wherein the upper and lower fastening tabs are secured to the corresponding upper and lower walls of the housing.

7. The interior upright set forth in claim 5 , wherein the upper and lower fastening tabs each define fastener openings.

8. The runway guidance sign set forth in claim 1 , wherein the interior upright is integrally formed from a one-piece sheet of metal.

9. The runway guidance sign set forth in claim 1 , further comprising a runway guidance sign panel secured to the housing at the front side.

10. The runway guidance sign set forth in claim 9 , furthering comprising a light source within the interior space of the housing and configured to backlight the runway guidance sign panel.

11. The runway guidance sign set forth in claim 10 , further comprising at least one foot secured to the lower wall of the housing and configured to elevate the housing about a runway.

12. The runway guidance sign set forth in claim 1 , wherein the housing further includes opposite side walls extending between the upper and lower walls, and a rear wall.

13. The runway guidance sign set forth in claim 1 , further comprising recesses in the front and rear ends of the body to provide clearance for structures within the interior space of the housing.

14. An interior upright for a runway guidance sign having a housing with upper and lower walls, the interior upright comprising:
a vertical body that is generally planar, the vertical body having opposite side faces, opposite front and rear ends, and upper and lower ends;
at least one upper fastening tab extending outward from at least one of the opposite side faces at the upper end of the vertical body, the at least one upper fastening tab configured to be fastened to the upper wall of the housing of the runway guidance sign; and
at least one lower fastening tab extending outward from at least one of the opposite side faces at the lower end of the vertical body, the at least one lower fastening tab configured to be fastened to the lower wall of the housing of the runway guidance sign,
wherein the interior upright is sized and shaped to be disposed between the upper and lower walls of the housing of the runway guidance sign and provide load-bearing support to the upper wall,
wherein the interior upright is integrally formed from a one-piece sheet of material, wherein the vertical body is free of openings extending through the opposite side faces, and wherein the at least one upper fastening tab and at least one lower fastening tab each define fastener openings.

15. The interior upright set forth in claim 14 , vertical body has first and second planar halves folded over one another about a fold line.

16. The interior upright set forth in claim 15 , wherein the first and second halves are mirror images of one another.

17. The interior upright set forth in claim 15 , wherein the interior upright is integrally formed from a one-piece sheet of metal.

18. A method of making a runway guidance sign comprising:
forming a housing defining an interior space and an opening at a front side, the housing including opposite upper and lower walls;
forming an interior upright from a one-piece sheet of metal, the interior upright including
a vertical body that is generally planar, the vertical body having opposite side faces, opposite front and rear ends, and upper and lower ends, the vertical body being free of openings extending through the opposite side faces,
at least one upper fastening tab extending outward from at least one of the opposite side faces at the upper end of the vertical body, and
at least one lower fastening tab extending outward from at least one of the opposite side faces at the lower end of the vertical body, wherein the at least one upper fastening tab and at least one lower fastening tab each define fastener openings;

fastening the at least one upper fastening tab to the upper wall of the housing within the interior space of the housing; and
fastening the at least one lower fastening tab to the lower wall of the housing within the interior space of the housing.

19. The method of making a runway guidance sign set forth in claim 18 , wherein said forming the interior upright comprises folding the one-piece sheet of metal about a fold line.

20. The method of making a runway guidance sign set forth in claim 19 , wherein said forming the interior upright comprises folding the at least one upper and lower fastening tabs out of plane relative to the vertical body.
