ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a temporary or semi-permanent shelter erectable from folded flat components. It also relates to a roof and wall reinforcing beams for such a shelter, also erectable from flat components.
BACKGROUND OF THE INVENTION
Recent disasters—earthquakes and floods—and political mobilizations and assemblies have demonstrated the need for temporary or semi-permanent shelters. Especially needed have been shelters whose components are easily stored and readily transported and are easily erected near the site of the disaster or wherever needed. Typically, such shelters have been in the form of fabric tents.
The present invention provides a temporary or semi-permanent shelter of more substantial nature, illustratively with rugged multi-ply, laminated corrugated board walls and roof. Prior to erection, the components are flat packages. The components together take on a three-dimensional shape in assembly and afford a substantial, durable, water-proof shelter which can be readily returned to flat condition when no longer needed. The word “Temporary” is used herein to indicate what is generally thought of as not being permanent. The durability of the present shelter may belie the name.
SUMMARY OF THE INVENTION
The invention is a shelter erectable on site comprising a wall assembly including hinged-together panels folded into a flat stack adapted in assembly to form a polygonal continuous side wall structure having a plurality of side walls. It also comprises a roof assembly including a plurality of flat generally triangular roof segments adapted to be arranged and connected with a vertex of each triangle directed to the same point, the base of each triangular segment being outward from the vertex, the total of the vertices adjacent the point being less than 360° so that, when assembled, the roof comes to a peak. The roof assembly is adapted to superpose the wall assembly with the bases of the triangular roof segments resting on the upper ends of the side walls respectively.
Further, the roof assembly includes a plurality of roof and wall attachment and reinforcement beams comprising flat sheets having generally trapezoidal shapes with long sides equal to the interior width of the respective walls, each sheet presenting three spaced fold lines parallel to the long side and marked or scored at different distances from the long side to define four connected side bands. These are a first, second and third side bands and an overlapping end band: Each sheet is adapted to be folded on the marked or pre-scored lines to form a triangular tubular beam with the overlapping band adhesively secured to the inside of the first band. In a preferred form of the invention, the second band is adhesively secured to the contiguous roof segment in the pre-erected condition. The tubular beams of the roof segments together form a downward curb secured to the roof and which fits snugly inside the polygon comprising the walls attach the roof and walls together and additionally there are mechanical means to further secure the roof and walls together if desired or necessary.
