A collapsible sun shelter that includes an arch support and a rollable flat mat that is configured to expand to include a canopy section and further includes a floor area portion, an upwardly deployable area portion at least two mat anchor points and at least two arch support openings. The rollable mat has an upwardly deployable area portion defined by an outer perimeter passing through at least one layer of the rollable flat mat such that the upwardly deployable area portion remains connected with the floor area portion when the upwardly deployable area portion is extended upwardly in a deployed configuration.

Apparatus for use in isolating a subject, the apparatus including a frame movable between collapsed and erected configurations, a body supported by the frame, wherein in the erected configuration, the body defines an internal volume for containing a subject to thereby substantially isolate the subject from a surrounding environment and a door actuator supported by the frame for moving a door between open and closed positions to thereby provide access to the internal volume.

An extendable and retractable column which is formed from at least three linked sections or chains. The linked sections include a plurality of individual segments linked end to end. As the linked segments are extended, each of the individual segments of the linked chains engage individual segments of adjacent linked sections to form a column. As the linked sections are retracted, each of the individual segments of the linked sections disengage from the individual segment of the adjacent linked sections and the individual linked sections may be rolled up into a multi-sided form for compact storage.

An elevatable building including a foundation (18) set into a ground surface and a platform (15) that, in the event of a flood, is to be elevated by a lifting mechanism (19). The building includes lightweight walls (14) and a roof assembled on the platform (15) to form a house. An adaptable connection (28) for utility services is provided which adjusts to the height from ground level of the platform when it is raised or lowered by the lifting mechanism so that vital service to the house can remain uninterrupted.

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 extendable and retractable column which is formed from at least three linked sections or chains. The linked sections include a plurality of individual segments linked end to end. As the linked segments are extended, each of the individual segments of the linked chains engage individual segments of adjacent linked sections to form a column. As the linked sections are retracted, each of the individual segments of the linked sections disengage from the individual segment of the adjacent linked sections and the individual linked sections may be rolled up into a multi-sided form for compact storage.

A manual or motor activated enclosure, appropriate for any surface to be enclosed, comprising matching opposite cross-linked structures containing a set of profiles that fits in the field of telescopic modular pivoting roof structures, that upon retraction it is housed underground such that none of its components are visible above ground, and upon deployment it achieves complete enclosure of the area while proving for openings.

A telescoping barrier assembly provides interlocking modules coupled together so as to slide vertically with respect to the other. The modules telescopically extend to a deployed position to form a barrier that withstands inertial and the external forces, and then retracts to a collapsed position. The modules include a base module and a plurality of deployable modules that are arranged in a nested configuration, such that each module slides in and out of an adjacent module. The base module has a mounting portion that may be subterranean. A lifting mechanism applies an axial force to the deployable modules to enable displacement between the operational and collapsed position. Spring biased lateral support members help the deployable modules remain in the extended position and a pulley system helps displace the modules to the collapsed position. An inner and outer seal inhibit liquid leakage between the module and between multiple adjacent assemblies.
