Abstract: A mobile performance stage is configurable between a compact transport condition to a performance condition with expanding deck wings and expanding canopy wings. The deck wings are carried directly on top of the main trailer deck and roll on tracks to deploy to the performance condition. The roof canopy includes a main roof element and two foldable roof wings. The roof wings pivot from fully open to a fully closed stowed condition below the main roof element to reduce the height of the stage when transported. Lift columns are hinged to reduce height. The roof wings may also be stored in a vertical position to provide side walls for a cargo trailer configuration. The roof may also be completely removed to form a deck only stage.

Abstract: A container assembly for rapid erection of portable buildings meets the following requirements: it is transportable by a single truck tractor, has dimensions which are customary and permissible for highway transport, and may be quickly erected on-site by simple means, whereby its floor space in the use mode is multiplied over that in the transporting mode and comprises two side containers swingably linked to a central container on the two longitudinal sides of the central container, whereby said side containers swing inwardly to fit one into the other and over the central container. When the assembly is in the swung-in transporting and storing position the available floor space is reduced to approximately one-third of that in the swung-out use position. The container assembly is particularly advantageous for use as a mobile hospital.
