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 base configured to be coupled to a structure in the cargo bay and having a first side and a second side;
a first support rail coupled to the base;
a second support rail coupled to the base, the second support rail spaced apart from the first support rail;
a first roller coupled to the base and configured to facilitate movement of a unit load device (ULD) across the cargo bay;
a second roller coupled to the base and configured to facilitate movement of the unit load device (ULD) across the cargo bay, the first support rail disposed between the first roller and the second roller, the second roller disposed between the first support rail and the second support rail;
a cradle for receiving a rail for restricting movement of the unit load device (ULD) in at least one direction, the cradle configured to position the rail between a first position and a second position, wherein the rail is closer to the second side of the base in the first position than when the rail is in the second position;
a plunger configured to be received by the base to resist movement of the plunger;
a first rail configuration with the cradle located on the first side, wherein the first rail configuration comprises the cradle positioned adjacent to the second support rail, the cradle restricted from movement along the base by being sandwiched between the plunger and the second support rail; and
a second rail configuration with the cradle located on the second side, wherein the second rail configuration comprises the cradle positioned adjacent to the first support rail, the cradle restricted from movement along the base by being sandwiched between the plunger and the first support rail.

2. The system of claim 1 , wherein the base further defines a slot configured to receive the plunger and the cradle such that placement of the plunger in the slot resists movement of the cradle.

3. The system of claim 1 , further comprising the rail configured to restrict movement of the unit load device (ULD) in the at least one direction, wherein:
the first rail configuration further comprises the rail coupled to the cradle, and
the second rail configuration further comprises the rail coupled to the cradle.
