The present disclosure relates to a protective enclosure to secure occupants against external threats, such as ballistic projectiles, blasts, or natural phenomena.

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.

A portable training studio is disclosed. The portable training studio includes an expandable structure that is reconfigurable between a transport configuration and a use configuration. The expandable structure includes: a frame; a first door that is pivotably connected to the frame such that the first door is movable between an open position and a closed position; and a first deck that is pivotably connected to the frame such that the first deck is movable between an open position and a closed position.

A folded building structure having a first roof portion, a second roof portion stacked on and pivotally connected to the first roof portion in a folded position, and a third roof portion stacked on and pivotally connected to the second roof portion in a folded position. The width of a transverse roof edge of the third roof portion is greater than the width of a transverse roof edge of the second roof portion and greater than the width of a transverse roof edge of the first roof portion.

A folded building structure comprising a fixed space portion including a rectangular floor or roof portion and a wall structure. The floor or roof portion has a longitudinal edge and comprises plural laminate panel sections, N in number, where N is equal to or greater than 2, and with each of the plural laminate panel sections having a rectangular shape with a first panel edge of span S, and two opposed orthogonal edges adjacent the first panel edge. The plural laminate panel sections are positioned adjacent each other with their orthogonal edges side-by-side, to provide N−1 pairs of adjacent panel sections with the longitudinal edge having a length equal to N×S. The wall structure adjoins the floor or roof portion and comprising a further laminate panel section having a rectangular shape and a second panel edge of span S, with the second panel edge vertically positioned so that the wall structure has a height equal to S.

A fork tube arrangement for facilitating the movement of a foldable transportable building.

Structural beams for a building structure that can be folded, to permit the creation of a compact building structure shipping module. The structural beams also can be unfolded and locked in the unfolded position to provide a rigid structure for resisting vertical loads and transferring them to lower levels and ultimately the building foundation.

A toe screw housing, for securing abutting enclosure components together, having a bearing plate with an interior face, an exterior face and a beveled upper edge; a toe screw well joined to and extending away from the interior face and including a fastener shelf; a toe screw support joined to the interior face, and additionally joined to and extending away from the fastener shelf, the toe screw support distal from the fastener shelf including a planar support surface oriented perpendicular to the interior face; and a fastener bore passing through the fastener shelf, the toe screw support and the support surface and inclined at a second angle relative to the interior face of the bearing plate.

A living space is disclosed including one or more adjustable or reconfigurable rooms. A room may be made reconfigurable by including fixed walls and a frame that is mounted to move in a first direction between a first position coextensive with the fixed walls and a second position that is extended relative to the fixed walls. The room may further include panels mounted in the frame configured to move in a second direction, orthogonal to the first direction, to seal off a front of the room. In examples, the panels may store against the frame when not in use.

A spacer system for stacked building structures that is in mating engagement with a seal plate provided on an edge of an enclosure component.
