Abstract

A system for repositioning rails in a cargo bay of an aircraft. The system includes a base configured to be coupled to a structure in the cargo bay and having a first side and a second side. The system further includes a cradle for receiving a rail for restricting movement of a unit load device (ULD) in at least one direction, the cradle configured to position the rail between a first position and a second position in which the rail is closer to the second side of the base than when the rail is in the second position.

First claim

What is claimed is:

1. A system for repositioning rails in a cargo bay of an aircraft, the system comprising:
a rail configured to restrict movement of a unit load device (ULD) in at least one direction;
a base configured to be coupled to a structure in the cargo bay and having a first side and a second side; and
a cradle configured to move the rail between a first position and a second position in which the rail is closer to the second side of the base than when the rail is in the first position, the cradle configured to remain in an upright position during a transition between the first position and the second position; and
at least one support arm coupled to the cradle and pivotably coupled to a pivot point on the base, wherein the cradle is configured to move the rail between the first position and the second position by pivoting the at least one support arm about the pivot point on the base.

2. The system of claim 1 , wherein the cradle includes a first wing extending away from the base and a second wing extending away from the base and located closer to the second side of the base than the first wing.

3. The system of claim 2 , wherein:
the first wing and the second wing each define a fastener aperture, and
the rail is configured to be retained in place relative to the cradle by extending a fastener through the fastener aperture of the first wing and the second wing and through the rail.

4. The system of claim 1 , wherein the at least one support arm includes two support arms each coupled to the pivot point on the base via a pin.

5. The system of claim 1 , wherein the at least one support arm is pivotably coupled to the cradle to facilitate alignment of the cradle relative to the base in both of the first position and the second position.

6. The system of claim 1 , further comprising a locking mechanism configured to lock the cradle the first position and the second position.

7. The system of claim 1 , further comprising a roller coupled to the base and configured to facilitate movement of the ULD across the cargo bay.

8. The system of claim 1 , wherein the cradle comprises a rail support, a first wing, and a second wing, the first wing extending outward from the rail support, the second wing extending outward from the rail support on an opposite side of the rail support from the first wing.

9. A system for repositioning rails in a cargo bay of an aircraft, the system comprising:
a rail configured to restrict movement of a unit load device (ULD) in at least one direction;
a base configured to be coupled to a structure in the cargo bay and having a first side and a second side;
a roller coupled to the base and configured to facilitate movement of the ULD across the cargo bay;
a cradle configured to move the rail between a first position and a second position in which the rail is closer to the second side of the base than when the rail is in the first position, the cradle configured to remain in an upright position during a transition between the first position and the second position; and
at least one support arm coupled to the cradle and pivotably coupled to a pivot point on the base, wherein the cradle is configured to move the rail between the first position and the second position by pivoting the at least one support arm about the pivot point on the base.

10. The system of claim 9 , wherein the at least one support arm includes two support arms each coupled to the pivot point on the base via a pin.

11. The system of claim 9 , wherein the at least one support arm is pivotably coupled to the cradle to facilitate alignment of the cradle relative to the base in both of the first position and the second position.

12. The system of claim 9 , wherein the cradle comprises a rail support, a first wing, and a second wing, the first wing extending outward from the rail support, the second wing extending outward from the rail support on an opposite side of the rail support from the first wing.

13. A system for repositioning rails in a cargo bay of an aircraft, the system comprising:
a rail configured to restrict movement of a unit load device (ULD) in at least one direction;
a base configured to be coupled to a structure in the cargo bay and having a first side and a second side;
a cradle having a first wing extending away from the base and a second wing extending away from the base and located closer to the second side of the base than the first wing, and the cradle being configured to move the rail between a first position and a second position in which the rail is closer to the second side of the base than when the rail is in the first position, the cradle configured to remain in an upright position during a transition between the first position and the second position; and
at least one support arm coupled to the cradle and pivotably coupled to a pivot point on the base, wherein the cradle is configured to move the rail between the first position and the second position by pivoting the at least one support arm about the pivot point on the base.

14. The system of claim 13 , wherein the at least one support arm is pivotably coupled to the cradle to facilitate alignment of the cradle relative to the base in both of the first position and the second position.
