Abstract

Cradle assemblies for supporting a door for uninstalling and/or installing the door to a fuselage of an aircraft, and arrangements and methods for the same are provided. In one example, a cradle assembly includes a first contoured board and a second contoured board that is spaced apart from the first contoured board. The first and second contoured boards are cooperatively configured to support outer sections of a first door. A third contoured board is configured to be selectively positioned adjacent to and extending higher than the first contoured board to support a first outer section of a second door that has a different outer shape than the first door. The third contoured board is contoured to substantially match the first outer section of the second door. The cradle assembly is configured to be positioned proximate to the fuselage.

First claim

What is claimed is:

1. A cradle assembly for supporting a door to a body of a vehicle, the cradle assembly comprising:
a first contoured board;
a second contoured board spaced apart from the first contoured board, wherein the first and second contoured boards are cooperatively configured to support outer sections of a first door;
a base, wherein the first and second contoured boards extend generally upward from the base, wherein the first contoured board has a first inboard side and a first outboard side that is opposite the first inboard side, and wherein the second contoured board has a second inboard side that faces the first inboard side and a second outboard side that is opposite the second inboard side;
a third contoured board configured to be selectively positioned adjacent to and extending higher than the first contoured board to support a first outer section of a second door that has a different outer shape than the first door, wherein the third contoured board is contoured to substantially match the first outer section of the second door, and wherein the cradle assembly is configured to be positioned proximate to the body; and
a fourth contoured board configured to be selectively positioned adjacent to and extending higher than the second contoured board to support a second outer surface of the second door, wherein the fourth contoured board is contoured to substantially match the second outer section of the second door, wherein the third contoured board and the fourth contoured board are hingedly coupled to the first contoured board and the second contoured board, respectively.

2. The cradle assembly of claim 1 , wherein the third contoured board has a first contoured edge that substantially matches a shape of the first outer section of the second door, and wherein the second contoured board has a second contoured edge that substantially matches a shape of corresponding outer sections of the first and second doors that are substantially similar to each other, and wherein other corresponding outer sections of the first and second doors have substantially different shapes than each other.

3. The cradle assembly of claim 2 , wherein the first and second contoured edges each have a substantially concave shape for supporting the second door.

4. The cradle assembly of claim 1 , wherein the third contoured board is hingedly coupled to the first inboard side of the first contoured board and the fourth contoured board is hingedly coupled to the second inboard side of the second contoured board.

5. The cradle assembly of claim 1 , further comprising:
at least one first arm disposed outboard of and coupled to the first outboard side of the first contoured board; and
at least one second arm disposed outboard of and coupled to the second outboard side of the second contoured board, wherein the at least one first arm and the at least one second arm cooperate to limit lateral movement of the first door and the second door.

6. The cradle assembly of claim 5 , further comprising:
at least one first layer of foam disposed along a third inboard side of the at least one first arm; and
at least one second layer of foam disposed along a fourth inboard side of the at least one second arm.

7. The cradle assembly of claim 5 , wherein the at least one first arm and the at least one second arm are independently adjustable in height relative the first and second contoured boards.

8. A method for supporting a door to a body of a vehicle, the method comprising the steps of:
supporting the cradle assembly of claim 1 on a table of a lift;
moving the table of the lift to advance the cradle assembly to a first position that is proximate to the body;
supporting the door with the cradle assembly; and
one of uninstalling and installing the door to the body while the door is supported by the cradle assembly in the first position.

9. A cradle assembly and lift arrangement for supporting a door to a body of a vehicle, the cradle assembly and lift arrangement comprising:
a lift comprising a table and configured to vertically move the table; and
a cradle assembly mounted on the table of the lift, the cradle assembly comprising:
a first contoured board;
a second contoured board spaced apart from the first contoured board, wherein the first and second contoured boards are cooperatively configured to support outer sections of a first door;
a base that is mounted to the table of the lift, wherein the first and second contoured boards extend generally upward from the base, wherein the first contoured board has a first inboard side and a first outboard side that is opposite the first inboard side, and wherein the second contoured board has a second inboard side that faces the first inboard side and a second outboard side that is opposite the second inboard side;
a third contoured board configured to be selectively positioned adjacent to and extending higher than the first contoured board to support a first outer section of a second door that has a different outer shape than the first door, wherein the third contoured board is contoured to substantially match the first outer section of the second door, and wherein the cradle assembly is configured to be positioned proximate to the body, and
a fourth contoured board configured to be selectively positioned adjacent to and extending higher than the second contoured board to support a second outer surface of the second door, wherein the fourth contoured board is contoured to substantially match the second outer section of the second door, wherein the third contoured board and the fourth contoured board are hingedly coupled to the first contoured board and the second contoured board, respectively.

10. The cradle assembly and lift arrangement of claim 9 , wherein the third contoured board is hingedly coupled to the first inboard side of the first contoured board and the fourth contoured board is hingedly coupled to the second inboard side of the second contoured board.
