A central locking apparatus for a folding tent includes a top plate, a bottom plate assembly, and a center rod disposed between the top plate and the bottom plate assembly. The bottom plate assembly includes a bottom plate, a wrench assembly rotatably connected to the bottom plate, and a limit sleeve slidably connected in the bottom plate. The wrench assembly abuts on the limit sleeve, and the wrench assembly is capable of driving the limit sleeve to slide. A limiting component is disposed at a lower end of the center rod, the limiting component may be built into the bottom plate to fit the limit sleeve in a locking manner, and a first elastic element is disposed between the limit sleeve and the bottom plate through fitting.

A foldable table and table legs comprises a tabletop comprising a plurality of tabletop sections each of which are interconnected by a hinge mechanism allowing the tabletop fold into a small, compact package. Detachable and foldable legs are configured for coupling to a table skirt comprising four segments which fold down from a storage pocket on the underside of the tabletop. The foldable legs interconnect with the table skirt once it is folded down from its storage position. The tabletop and foldable legs may all be folded into a compact, portable and packable configuration.

A flexible hinge created by a section of fabric material disposed between upper and lower retention pieces, for creating a hinge from a fabric member.

A T-link hinge for hingeably connecting first and second members comprises a link portion having a T-shaped cross-section including a top region and a bottom region, wherein the top region has a width greater than a width of the bottom region. The link portion comprises first and second thru holes formed in the bottom region of the link portion adjacent each the respective first and second ends of the link portion. Each of the first and second members to which the link portion is to be mounted includes thru holes. In an assembled configuration of the link portion and the first and second members, the thru holes formed on the first and second members axially align with the pair of thru holes in the link portion and are connected by first and second pins.

Systems, methods, and apparatus include a modular tent comprising an upper tent portion having a first base surface area, wherein the upper tent portion does not include a floor surface; and a base extension that includes a floor surface having a second base surface area, the second base surface area being larger than the first base surface area, wherein the base extension is removably secured to the upper tent portion, wherein the base extension, when secured to the upper tent portion, results in a base surface area of the modular tent increasing to the second base surface area.

A tent is designed for use in the air, connected at its vertices to trees or the like. The tent is further designed with enough support from an independent support structure to create a shelter there-in while in the air or on the ground. Further, the tent is built atop a floating mat or base. In order to provide enough strength to the base that it can be used to float the entire tent or hold the tent airborne, straps extend from each vertex of the mat through a central portal and connect back to themselves. From these straps, loops are further created to attach the tent, by way of the loops, to trees while the entirety of the mat is buoyant enough to hold the tent and people there-in afloat.

A tent system including: a fabric member including a body portion and a bottom portion to form a resident space; a fixing device disposed at the fabric member and including a mesh pocket, an upper clip, a lower clip and a side clip; a main pole coupled to the fabric member in an X-shape through the fixing device, in which one end and an opposite end of the main pole are supported by the mesh pocket and the lower clip, respectively; and an adjusting device that allows at least one of the fixing device and the main pole to have a variable structure. The tent is easily installed and disassembled even by one person with a simple structure and maintains a tight supported state to the ground, so that usability is improved in cost-effectiveness.

A containment airlock, in particular an airlock for intervention on a site likely to be contaminated with radiation, asbestos and biological and/or chemical agents. The containment airlock comprises a self-supporting frame and a flexible containment shell. The shell is configured to be assembled with the frame. The frame is articulated so as to be extensible between a folded storage position and an extended intervention position. The frame comprises articulated reinforcement rods. The articulated reinforcement rods comprise rigid segments and at least one intermediate articulation connecting the segments.

The present invention relates to an insect repellant tent. The an insect repellant tent comprises a frame structure comprising a base ring comprised to a plurality of ring sections, a plurality of poles connectable to the plurality of ring sections, a plurality of connectors for connecting the plurality of ring sections with the plurality of poles, wherein the connector comprises a connector means and a handle means, wherein the connector means is configured to receive the plurality of ring sections, the pole, and the handle section, a top cap to which the plurality of poles connect while extending from the plurality of connectors, wherein the plurality of ring sections, the top cap, the plurality of poles, and the plurality of connectors define a dome like structure in an assembled configuration thereof. The tent further comprises at least one floatation means provided on the plurality of ring sections, and an insect repellant sheet for covering frame structure.

The present invention discloses a rooftop fall protection system including a plurality of mast assemblies and at least one ladder assembly removably engaged with the mast assembly. The ladder facilitates the elevation of a human to an elevated surface on a structure. Each of the ladder assemblies and mast assemblies are coupled to at least one cross-member positioned at a height above the perimeter of the elevated surface. The cross-member protects the human from falling from the elevated surface of the structure.
