MULTIPLE USE FREIGHT DECK A deck structure for use in loading a transportation vehcile comprises a main deck portion having a plurality of parallel spaced elongate rail members attached at each end to a sleeve together with a pair of support portions each formed from parallel rail members similar to the rail members of the deck portion attached at one end to a pipe inserted in the sleeves of the deck portion. This allows each side portion to pivot relative to the main deck portion about the axis of the pipe. The rail members are perforated transversely and have channels longitudinally which allow the communication of air. The rail members of the side portions are interleaved with the rail members of the main deck portion so that the side portions can fold to a collapsed condition within the plane of the main deck portion. The device can be used to support a second load above a first load on the floor of the vehicle; to act as a bulkhead across the vehicle; to provide air channels along the sides and/or floor of the vehicle.
