Abstract
A collapsible cargo container (20) includes a lower portion (22) which is surrounded and slidably received by an upper portion (44). Upper portion (44) may be raised and locked in a fully extended position wherein collapsible cargo container (20) has the dimensions and connection interfaces of a conventional cargo container. Alternatively, upper portion (44) may be lowered onto lower portion (22) so that the volume of collapsible container (20) is approximately one-half that of a convention cargo container. A plurality of connectors (70) hold the walls of the upper portion (44) and lower portion (22) together in either the fully extended or fully collapsed positions. Four hinged corner posts (36a-d) permit upper portion (44) to reside on lower portion (22) in either a fully extended or fully collapsed position.
