Abstract
A mobile container system for providing rooms for human occupancy having flat plate wall elements, each having a polyurethane foam core coated with aluminum or glass fibers. The walls are arranged into cube-like structures, and the cubic structures may be joined together. Each wall edge has a joint fastened on it with a projection extending outward from the edge with an arrow shaft and arrow head shape cross-section. The arrow head shape is thicker than the shaft. Angles are provided to interlock the wall elements by the projections. The angles have sockets conforming in shape to the projections. The walls of the socket may be pushed apart by turning an oval-shaped member lying therebetween to allow the arrow head to pass between the walls and into an accommodating area of the socket.
