Abstract
A roller tray assembly has a plurality of roller wheels mounted on the floor of a loading platform of a vehicle such as an aircraft or truck. The roller wheels are free to roll either in the loading or unloading directions to permit cargo to be loaded or unloaded on such wheels. Braking rollers are installed on the loading platform floor, the cargo load being moved over such braking rollers. Each braking roller has a central hub supported on unidirectional clutch bearings such that the roller is free to rotate in one direction but locked by the bearings against rotation in the opposite direction. The outer wall of the central hub is covered with an elastomer. The roller has an outer cylindrical wall against which the cargo abuts. The ends of the cylindrical wall have end covers between which a plurality of rods are mounted. These rods abut against the elastomer with sufficient pressure to deform the elastomer. The central hub is rotatably mounted on a fixed shaft. The assembly is free to rotate in one direction. In the opposite direction, the clutch bearings prevent the central hub from rotating. The hub outer wall, however, carries the rods around against the elastomer which is deformed by the rods. This permits motion against resistive force opposing such motion.
