A foldable blast proof protective structure comprising a foldable walls envelope with integrated door, a detachable ceiling and a detachable floor, wherein such a modular design of the structure enables a complete assembly within a few simple steps, for which no special tools or heavy cranes are required.

A construction material structure, comprising a plurality of inner support columns, the support columns being fixtured at the top end portion and/or the bottom end portion in a generally parallel, spaced apart arrangement, a polymeric film stretched across a first side and an opposite second side of the support columns, a quick cure polymeric fibrous material formed on the outer surface of the stretched polymeric film, and a polymeric foam disposed between the support columns and the stretched polymeric film.

A building panel is constructed of a corrugated material. The panel can be folded into a U-shaped configuration. Successive folded panels can be coupled together using complementary shaped corrugations to fix panels in position relative to each other. Shaped connectors can be used to connect building panels in one plane to building panels in another plane.

A collapsible dwelling includes a front wall assembly, a rear wall assembly, opposed sidewall assemblies, a roof assembly and a floor assembly. The wall assemblies are collapsible to be received between the floor assembly and the roof assembly, and at least one of the roof assembly and the floor assembly defines at least one recess, the, or each, recess being dimensioned to receive an appliance that is mounted on one of the wall assemblies when that wall assembly is in a collapsed configuration.

Disclosed herein is a protective enclosure deployable within an interior space such as a school classroom or an office, or an exterior space. The deployable protective enclosure is to protect multiple occupants against projectiles such as flying or falling debris resulting from a natural disaster such as a tornado, hurricane or earthquake, or rounds fired. Occupants may be corralled into the protective enclosure and be protected against projectiles. The protective enclosure comprises three or more articulated partitions comprising ballistic materials or high-impact resistant materials. The protective enclosure may be affixed to one wall or two walls at a corner of a classroom, office or other space. The articulated partitions may be readily and rapidly secured in a protective configuration, forming a triangular, square or other polygonal enclosure. When not in use, the partitions may be folded and stowed against the walls.

Embodiments may relate to a foldable play structure which may be easily assembled and which may be form of four or more panels each connected to another to provide an accordion fold structure; corner hinges comprising a first hinge portion attached to one panel of the at least four panels; a second hinge portion attached to another panel of the at least four panels; and a fastener configured to be retained within either the first portion or the second portion; and mid-wall hinge(s) attached to two of the panels and located between the corner hinges. Typically, in a first configuration, the panels of the accordion fold structure are folded to be stacked in substantially parallel planes, and in a second configuration, the panels are unfolded forming a play structure. The retained fastener may be used to secure the corner panels together.

Disclosed is a popup camper having a base, a top, a first sidewall having a first edge, a second sidewall having a second edge, a third sidewall connected to the top at a third edge, and connected to the base at a fourth edge, and six panels of the third sidewall. The first panel is adjacent to the third edge, the second panel, the third panel, and the fourth panel, the second panel is adjacent to the base, the first panel, the fifth panel, and the sixth panel, the third panel is adjacent the first edge, the first panel, and the fifth panel, wherein the fourth panel is adjacent the first panel, the second edge, and the sixth panel, the fifth panel is adjacent the first edge, the second panel, and the third panel; and the sixth panel is adjacent the second panel, the second edge, and the fourth panel.

A shelter or camper that provides improved portability and protection. The shelter or camper may include rigid walls to offer greater protection from weather, animals, and theft. The shelter or camper may be transitionable between different configurations for different purposes, including an open and expanded configuration for use as a shelter, camper, or sleeping quarters and a compact, closed case configuration for easy storage and transport. To facilitate this, the walls may be foldable, expandable, or collapsible. When the walls are folded or collapsed, roof and floor sections may be connected to each other and may enclose the folded, collapsed walls and internal components within the collapsed closed case.

An enclosure component having a thickness for a building structure having an interior sheathing layer comprising paper; a first structural layer bonded to the interior sheathing layer and comprising a first generally rectangular structural panel of magnesium oxide arranged in a side-by-side relationship with a second generally rectangular structural panel of magnesium oxide to define a first structural panel seam between the first and second structural panels. There is a first binding strip of magnesium oxide positioned over the first structural panel seam and fastened to form a lap joint with the first structural panel and with the second structural panel, so as to bond together the first and second structural panes. The enclosure component includes a first strengthening layer, comprising woven fiber mat, bonded to the first structural layer; and a foam layer with first and second opposing faces comprising a first generally rectangular foam panel and a second generally rectangular foam panel arranged in a side-by-side relationship to define a foam panel seam between the first and second foam panels. The first structural panel seam is offset from the foam panel seam a select distance in a direction generally perpendicular to the thickness. The first strengthening layer is bonded to the first opposing face of the foam layer. The enclosure component also has a second structural layer comprising a third generally rectangular structural panel of magnesium oxide arranged in a side-by-side relationship with a fourth generally rectangular structural panel of magnesium oxide to define a second structural panel seam between the third and fourth structural panels. There is a second binding strip of magnesium oxide positioned over the second structural panel seam and fastened to form a lap joint with the third structural panel and with the fourth structural panel, so as to bond together the third and fourth structural panels. The second structural panel seam is offset from the foam panel seam a select distance in a direction generally perpendicular to the thickness; and the second structural layer is bonded to the second opposing face of the foam layer.
