Abstract

A protection apparatus employed in the construction of aircraft can be collapsed to a small configuration to enable insertion of the apparatus to access openings in a structure of the aircraft, for example an access opening in a wing of the aircraft, to position the protection apparatus inside the aircraft structure. Once inside the aircraft structure, the protection apparatus can be expanded from its collapsed configuration and positioned over components in the aircraft structure, for example hydraulic tubing or electric wiring, to protect those components from damage by a worker working in the aircraft structure above the components.

First claim

The invention claimed is:

1. A protection apparatus comprising:
a support surface on a top of the protection apparatus and a bottom surface on a bottom of the protection apparatus;
a first support leg on the bottom surface, the first support let projecting outwardly from the bottom surface to a distal end of the first support leg, the first support leg being fixed at an angle relative to the support surface;
a second support leg on the bottom surface, the second support leg projecting outwardly from the bottom surface to a distal end of the second support leg, the second support leg being fixed at an angle relative to the support surface;
the first support leg and the second support leg being movable toward and away from each other;
with the first support leg and the second support leg being moved away from each other, the distal end of the first support leg and the distal end of the second support leg are positioned at opposite sides of the support surface at a distance apart that corresponds to a spacing between adjacent stringers of an aircraft structure that enables the first support leg and the second support leg to be positioned between the adjacent stringers of the aircraft structure and support the support structure over components of the aircraft structure between the adjacent stringers;
a first part of the protection apparatus, the first part having a first support surface area that is a portion of the support surface on the top of the protection apparatus, and the first part having a first bottom surface area that is a portion of the bottom surface on the bottom of the protection apparatus;
the first support leg being on the first bottom surface area;
a second part of the protection apparatus, the second part of the protection apparatus having a second support surface area that is a portion of the support surface on the top of the protection apparatus, and the second part having a second bottom surface area that is a portion of the bottom surface on the bottom of the protection apparatus;
the second support leg being on the second bottom surface area;
the first part and the second part being separate parts of the protection apparatus;
a connection connecting the first part and the second part; and,
the first part and the second part being mirror images of each other.

2. The protection apparatus of claim 1 , further comprising:
the support surface being a flat surface.

3. The protection apparatus of claim 1 , further comprising:
the first support surface area being a flat surface; and,
the second support surface area being a flat surface.

4. The protection apparatus of claim 1 , further comprising:
the connection enabling the first part and the second part to move relative to each other.

5. The protection apparatus of claim 1 , further comprising:
the connection enabling the first part and the second part to pivot relative to each other.

6. The protection apparatus of claim 1 , further comprising:
the connection enabling the first part and the second part to move between first relative positions and second relative positions of the first part and the second part where in the first relative positions the distal end of the first support leg and the distal end of the second support leg are adjacent and the first support surface area and the second support surface area are oriented at an angle and in the second relative positions the distal end of the first support leg and the distal end of the second support leg are spaced the distance apart and the first support surface area and the second support surface area form a continuous support surface.

7. The protection apparatus of claim 1 , further comprising:
a first surface extension, the first surface extension extending from the support surface outwardly from the first support leg; and,
a second surface extension, the second surface extension extending from the support surface outwardly from the second support leg.

8. The protection apparatus of claim 1 , further comprising:
the protection apparatus is constructed of a rigid plastic configuring the protection apparatus for manual manipulation and movement by a worker.

9. The protection apparatus of claim 1 , further comprising:
the first part is formed with a plurality of hinge knuckles;
the second part is formed with a plurality of hinged knuckles; and,
the hinge knuckles of the first part are positioned to alternate with the hinge knuckles of the second part.

10. The protection apparatus of claim 1 , further comprising:
the first support leg and the second support leg are configured for positioning against the adjacent stringers of the aircraft structure providing further support to the protection apparatus.

11. A protection apparatus comprising:
a first part of the protection apparatus, the first part having a first support surface area on a top of the first part and a first bottom surface area on a bottom of the first part;
a first support leg on the first bottom surface of the first part, the first support leg being fixed at an angle relative to the first support surface area, the first support leg projecting outwardly from the first bottom surface to a distal end of the first support leg;
a second part of the protection apparatus, the second part having a second support surface area on a top of the second part and a second bottom surface area on a bottom of the second part;
a second support leg on the second bottom surface area of the second part, the second support leg being fixed at an angle relative to the second support surface area, the second support leg projecting outwardly from the second bottom surface area to a distal end of the second support leg;
a connection between the first part and the second part, the connection enabling the first part and the second part to move between first relative positions and second relative positions of the first part and the second part where in the first relative positions the distal end of the first support leg and the distal end of the second support leg are adjacent and the first support surface area and the second support surface area are oriented at an angle and in the second relative positions the distal end of the first support leg and the distal end of the second support leg are spaced a distance apart and the first support surface area and the second support surface area form a continuous support surface; and,
the first part and the second part being mirror images of each other.

12. The protection apparatus of claim 11 , further comprising:
the first support leg projecting outwardly from an outboard edge of the first support surface area; and,
the second support leg projecting outwardly from an outboard edge of the second support surface area.

13. The protection apparatus of claim 11 , further comprising:
the first support surface area being a flat surface; and,
the second support surface area being a flat surface.

14. The protection apparatus of claim 11 , further comprising:
the connection between the first part and the second part being a hinge that enables the first part and the second part to pivot relative to each other.

15. The protection apparatus of claim 11 , further comprising:
in the first relative positions of the first part and the second part the distal end of the first support leg and the distal end of the second support leg contact.

16. The protection apparatus of claim 11 , further comprising:
the first support surface area being planar, the first support surface area having a general rectangular configuration with an inboard edge and an outboard edge on op
