ABSTRACT:
A constructional kit comprising elongated connectors and panels. The elongated connectors can only be joined to panels and the panels can only be joined to connectors. Elongated connectors have no means by which they can be joined to other elongated connectors, and panels have no means by which they can be joined to other panels. The elongated connectors comprise a number of longitudinal grooves into which edges of the panels may be pressibly fitted. Certain panels formed as doors and windows are provided with oppositely extending, axially aligned pins. The elongated connectors further comprise holes formed within each groove for pivotally mounting the pin-bearing panels.
