A tent for surrounding a base of an upstanding structure on a support surface is disclosed. The tent features a covering with a top edge arranged to follow a perimeter of the structure base and a bottom edge arranged to define an outer periphery of the covering. The tent additionally features a base strap arranged for forming a closed loop about the structure base at a predetermined height above the support surface. The base strap supports a first attachment member, and a second attachment member is located along the top edge of the covering for cooperating with the first attachment member to fasten the covering at the structure base. A tightening strap along the top edge of the covering but behind the second attachment member is arranged to follow the base strap to seal connection of the covering and the base strap.

A pneumatic tent (1) with at least one pole (2) extending in final assembly position vertically from the mounting surface (8) and a dome-shaped tent cover (3) extending over the self-supporting pole (2) which is locked and tensioned with locking means (4) in relation to the mounting surface (8), wherein the pole (2) containing a pressurized filling gas is constructed as single or multiple layered and includes a controllable or adjustable illumination device (5) that is placed inside the pole (2).

A tent center hub, having a frame that hinges with top rods of the tent, also containing a top seat wherein a solar energy conversion and storage mechanism is mounted; a bottom side of the top seat is provided with an annular press ring protruded away from the top seat; a top side of the frame is provided with an annular block ring protruded away from the frame; the top seat is removably connected to the top side of the frame; a cavity inside the top seat and a cavity inside the frame are in mutual communication with each other; the block ring is disposed within an enclosure of the press ring; a gap exists along a longitudinal direction between a bottom side of the press ring and the frame. The tent center hub can provide lighting inside the tent.

A retractable enclosure includes at least two displaceable structural bow frames which each define a roof section and opposed upwardly extending side sections. These sections are interconnected by joint connectors. The sections are also formed of extruded profiled straight metal tubes which have extruded interconnection channels. The tarp sections of flexible material are engaged by channels of some of the bow frames and collapse and expand as the bow frames are displaced closer or away from one another. Access to the enclosure can be provided from all sides thereof for access to its interior.

A structural tent intended for use as a living space able to withstand extreme temperatures, while still being comfortable and used on a temporary basis; comprising a frame on which there are assembled first profiles and lower posts which are attached to a plurality of second profiles, brackets and upper posts, which form the structure on which a ridgepole is supported; and where a filler material is introduced into the gap created between the frame and the outside fabric; and where, finally, the ridgepole is integrally supported on the upper posts, where honeycomb plates are supported, an impermeable roof being arranged on the honeycomb plates and the gaps in the honeycomb plates being filled with a fine granular material.

A tension-release mechanism configured to facilitate a coupling between a shade membrane and a support structure is provided. The tension-release mechanism comprises a coupling sleeve configured to be installed within the support structure. The tension-release mechanism also comprises a tension actuation element configured to extend along a connection path within the coupling sleeve. The tension actuation element is configured to engage a receiving feature within a moveable sleeve coupled to the shade membrane. Actuating the tension actuation element in a first direction causes the moveable sleeve to be received within the coupling sleeve. Actuation in a second direction causes the moveable sleeve to be decoupled from the coupling sleeve.

An 11-device-in-one system (which can be used as 360-degree-rotatable rollable portable lockable collapsible expandable carport, green house, gazebo, storage, attic, awnings, tent, workshop, outdoor tables, booth, and RV port) comprises: round bars; square bars releaseably attached to the round bars; 360-degree rotatable lockable wheels rotatably attached to the round bars; canvas roof panels; canvas side panels; canvas end panels; canvas gap-covering panels; panel-lifting Velcros sewn to the side and gap-covering panels; panel-sealing zippers sewn to the end panels (for forming doors); panel-sealing grommets attached to the roof, side, and end panels; bungee cords and balls inserted through the grommets (for attaching the roof, side, and end panels together); first telescopic arms foldably and releaseably attached to the round bars; second telescopic arms foldably attached to the first telescopic arms; feet welded to the second telescopic arms (for attaching to each other over the roof panels to form the frames for booth signs); and toes welded to the round bars (for releaseably locking the feet thereon to form the frames for awnings and tables).

Disclosed is a shelter having a base having base buses; a frame having curves and beams supporting the curves. Each end of the curves are attached to corresponding base bus; each curve is composed of curved elements, the curved element has means for connecting a curve to another curve with a beam. The shelter further has a cable, which cable is for tightening and supporting the frame. Additionally, there is a curved element, and a use of a shelter as a shelter for aircrafts or as a sports hall.
