  • FIG. 12 is a wiring diagram of the electrical circuitry of the enclosure.
  • FIG. 1 Three different types of wall panels are arranged to form the sides of the portable enclosures. These panel types (2, 8 and 7) are the basic building blocks utilized in the design of the enclosure. Each of the panels are interchangeable with each other and designed to perform specific functions in accordance with the overall design of the enclosure. By the use of center support members 30 and comer support members 31, the individual wall panels are rigidly joined together in any desired combination to form a specific enclosure of any desired shape.
  • Wall panel 7 is designed to accommodate door 6.
  • Wall panel 7 is fabricated from a couple of sheets of stock metal sheeting cut to the desired panel size and separated by and welded to channel members which appear about the perimeter of the panel. An opening is made within the panel to house door 6.
