A protective enclosure or cab for an operator of a walk-behind or mechanical device, such as a snow blower, engine-driven snow thrower, ride-on tractor, or the like, is provided. The protective enclosure or cab includes an inflatable frame structure which supports a plurality of transparent, flexible windows or a single sheet of transparent material such as a curtain. When inflated, the protective cab is detachably coupled to the walk-behind or mechanical device and surrounds an operator of the walk-behind or mechanical device protecting the operator from the environment such wind, rain, snow or the like, while providing an unobstructed view of the surrouding environment. When deflated, the protective enclosure or cab can be folded into a small volume to be placed in a storage device which can be coupled to the walk-behind or mechanical device.

A device for draining a liquid from a first film layer which forms at least one part of a building cladding element. A first valve element can be arranged in the region of a first opening of the first film layer such that the valve element can be pivoted between a first position, which closes the first opening, and a second position, which at least partly releases the first opening. Additionally, a first opening and closing are configured to keep the first valve element in the first position if pressure of a liquid is less than or equal to a threshold, allow the first valve element to pivot from the first position to the second position if the pressure of the liquid exceeds the threshold, and pivot the first valve element from the second position to the first position if the pressure is substantially no longer present.

A rooftop tent includes a frame and a canopy, a first inlet is provided on the frame, and a side of the canopy is provided with an entrance; and a baseboard, which is inflatable and a second inlet in provided on a side of the baseboard. The frame is inflatable and air is inflated into the frame by the first inlet, such that the canopy is supported. A second inlet is located on the side of the baseboard, and the air is inflated into the baseboard through the second inlet, such that the baseboard is unfolded into a panel, which is used to support and carry the tent body. A receiving apparatus of the rooftop tent is also provided.

Transportable and rapidly deployable air supported structure systems and related methods are disclosed. The air supported structure systems include at least one transportable container. The systems also include a flexible outer membrane configured to couple to a base in a substantially air-tight manner. The systems further include at least one air handling mechanism contained within the at least one container configured to force air between the outer membrane and the base to form an enclosure therebetween via internal air pressure. The systems are configurable between a packaged state with the outer membrane contained within the at least one container, and a deployed state with the outer membrane being coupled to the base and the at least one air handling mechanism forming the enclosure via the internal air pressure. The at least one container may form a portion of the base and/or provide for ingress and egress with the enclosure.

A portable expandable device with a contracting mechanism which allows for many forms of recreational products and structures to be expanded, reinforced in the expanded shape, and then contracted easily to regain its portable form. The expansion means is exercised by the use of at least one of the following, resiliently extending, unfolding, inflating, as to become an expanding form which can then be easily retracted to the redeployed form. The retraction mechanism reverses the expansion process utilizing a mechanism which sequentially exerts the forces needed in the proper locations in order to ensure proper contraction. Disclosed embodiments utilized supplemental structural reinforcement of the expanded form through the use of joints, releasable interlocks, latching mechanisms, air bladders, to ensure the form is stable and usable. The objective being a stable structure with a rapid and easy deployment and a supplemental retraction means as to be easily transportable.

The detailed principle, structure, manufacture and designing method of a retractable roof for large stadiums or other huge spaces are established. This roof is formed by using a number of connected and paralleled inflatable arc shaped tubes (called “air beams”) made of soft material (membrane). Using successive inflation to the tubes can realize deploying of the roof, and using successive deflation of tubes can realize retraction of the roof. All these processes can be completed by an automatically controlled program. A rigorous mathematics derivation and mechanics proof show that, the retractable air beam roof with durable membrane of ordinary durability can have a large span of over 100 meters, and can withstand in a regularly extreme (critical) weather (heavy wind, rain, snow and hail). The outstanding strong point of this kind of retractable roof is absolutely safe for spectators and performers (or competitors) inside the stadium.

A chemical/biological vehicle survivability barrier (CVSB) has an inflatable air beam shelter (IABS), also referred to as a tunnel-like enclosure, for inserting and coupling to the interior of a vehicle. The CVSB further has at least one air handling and power unit (AHPU) coupled to an exterior fitting of the IABS. The AHPU withdraws potentially contaminated air from inside the tunnel-like enclosure, filtrates the air by removing contaminants from the air withdrawn, and returns the filtrated air back into the tunnel-like enclosure.

A portable, inflatable canopy is disclosed having an inflatable support system comprising interconnected, intersecting arches over which a tarp is secured to form a dome structure that can be temporarily anchored to the ground as a respite for sun, heat, wind, and rain. The inflatable support system works with a battery powered fan to inflate the canopy quickly without outside power requirements, and the fan can also be used to quickly deflate the canopy. The use of all soft materials allows the canopy to be folded or rolled when deflated into a compact storage configuration without poles, rigid supports, or other cumbersome elements.

The present disclosure relates to deployable structures and methods of use thereof. In particular, deployable structures with non-cylindrical or irregular shapes and methods of use thereof are disclosed. Non-cylindrical combustion elements can be used to rigidize such non-cylindrical or irregular shapes. The use of gaseous oxidizers along with deployable structures is also disclosed.
