This present invention relates to a vehicle cargo area or bed cover that forms an enclosed space for use in the vehicle bed. The cover is easy to install and remove for a single person and includes a series of lightweight panels, held together by framing elements and installed on the side rails of the truck bed. The lightweight panels are attached at the top to form the top panel. A rear panel is installed on top of the rear wall of the truck bed and an aerodynamic portion is positioned on the top of the cabin of the vehicle. The enclosure can be accessed by opening a door positioned on the tailgate or front end of the truck bed. The enclosure has LED lights for illumination and fans and windows for ventilation.

A clearspan structure including component systems, and methods of forming a clearspan structure including component systems, for mitigating hazards to personnel or equipment from explosions, fires, toxic material release, and other hazards in hazardous locations. The exemplary clearspan structure is also capable of withstanding environmental conditions such as snow loads and wind. The exemplary clearspan structure is, for example, a tent or fabric structure which includes a plurality of frame members forming a support system for the clearspan structure, and fabric roof portions and walls for enclosing the clearspan structure.

A portable variable volume paint spray enclosure or booth includes a frame assembled from longitudinal members and detachable clamps. The clamps secure together adjacent ends of the longitudinal members. The paint spray enclosure further includes a flexible cover disposed upon the frame such that a relatively air tight enclosure having a predetermined configuration is formed. The assembled frame and flexible cover extend from grade level to a predetermined elevation to encase an object to be painted. The paint spray enclosure also includes an air flow input apparatus for allowing air flow into the enclosure, and an air extraction apparatus/air scrubber for removing air from the enclosure, such that air mixed with vaporized paint inside the enclosure is removed from the enclosure before the paint vapor and air combine to form an explosive mixture, thereby preventing an explosion and/or fire from occurring inside the enclosure, and preventing operators from being exposed to harmful fumes. The air scrubber removes the paint vapor from the air as the combination exits the enclosure, thereby allowing only “clean” air back into the atmosphere.

The invention provides a building assembly comprising a subterranean cellar defining a space to be formed under the ground, the cellar having a ceiling including a first opening defining an access region for a staircase to connect the ground of the subterranean cellar, when in situ, with the surface of the ground above the cellar; and a heat control device having a heat transfer mechanism to provide heat from the cellar to a region on the ground above the cellar.

A pop up cover for a crib is provided for providing a safe, comfortable and isolated environment for a child in a crib. The pop-up cover may be made of breathable fabric panels having an integrated frame, for example a flexible frame, which can be folded (collapsed) on itself, for example when folded in specific ways if appropriate force is applied and which keeps the fabric in a taught, open position when unfolded (preventing the panels form falling inwards onto each other). The pop up cover can be lightweight and compact, quick and easy to set up, dark inside and breathable.
