A shelter of the type having collapsed and expanded configurations. In one of several example embodiments, the expanded configuration includes a tunnel-shaped portion forming a pair of opposing side walls and a roof section. The roof section has a peak positioned above the side walls and the tunnel-shaped portion may include opposing ends with a first opening at the first end and a second opening at the second end, each opening capable of accommodating an end wall. A first sheet is foldable along at least first and second crease lines to define the walls and roof section, the walls having an upper separation distance between the first and second crease lines when the shelter is expanded. The first sheet is segmented into panels with pairs of adjoining panels forming pleats each having a vertex extending from a crease line to an adjoining footing flap, the walls having a lower separation distance between footing flaps on different walls when the shelter is expanded. The lower separation distance is greater than the upper separation distance resulting in at least one of the walls being canted with respect to a vertical orientation.

Collapsible shelter

The present invention a collapsible shelter comprises spaced apart first and second upright pleated wall sections disposed substantially parallel to each other, first and second slanted pleated roof sections joined at upper ends to form a saw tooth roof peak, and joined at lower ends to upper ends of said wall section to form saw tooth wall-roof junctions, wherein said pleated wall sections together with said pleated roof sections form a tunnel member which is collapsible by folding said pleated sections onto each other in accordion style. Preferably the collapsible shelter further comprising a flat floor panel having straight parallel longitudinal creases defining floor panels, each floor panel operably corresponding to a wall panel and said floor further including an axial crease along an axis running in a transverse direction; wherein said flat floor panel is connected to lower ends of said wall section (defining a tunnel section) and collapses together with said tunnel member in accordion style, to a collapsed position, by firstly folding said floor along said axial crease, prior to folding said pleated section onto each other.
