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.
A foldable shelter, configurable in a collapsed shape and in an expanded shape, comprising a sheet for forming wall sections and roof sections of the shelter, said sheet having first and second opposing sides, a first fold line central to the sheet and second and third fold lines each positioned in the sheet on a different side of the first fold line, the second and third lines each formed in canted orientation with respect to the first fold line and extending from the first side to the second side.
A shelter system, comprising:
A shelter system, configurable in a collapsed shape and in an expanded shape, comprising first and second sheets each configurable into a tunnel shape having first and second openings at opposing ends of the tunnel shape, a roof section and a pair of opposing wall sections each extending to the roof section, each sheet having first and second opposing side edges, with the first side edge positionable to define the first opening and the second side edge positionable to define the second opening,
A method of forming a shelter system of the type configurable in a collapsed shape and in an expanded shape, formed with at least first and second overlapping sheets that form a tunnel shape shelter having roof and wall sections, each sheet having first and second opposing side edges, the method comprising:
A shelter of the type having collapsed and expanded configurations, the expanded configuration including a tunnel-shaped portion forming a pair of opposing side walls and a roof section, the roof section having a peak positioned above the side walls, the tunnel-shaped portion including 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 along portions of the side walls and roof section, the shelter comprising:
