An air filtering shelter 100 comprising a shelter frame 110 comprising a plurality of frame members 112 defining a sheltered area 102. Filter media 120 extends across the plurality of frame members 112, where the filter media 120 is disposed over the sheltered area 102. An airflow guide 130 extends across the plurality of frame members 112 between the sheltered area 102 and the filter media 120. The airflow guide 130 is impermeable and the filter media 120 and the airflow guide 130 define an airflow channel 125 between them. An airflow generator 140-1 is coupled to the shelter frame 110. The airflow generator 140-1 has an inlet 142 in the airflow channel 125 and an outlet 144 in the sheltered area 102.

A portable barrier includes a junction assembly having a first junction support, a second junction support, and a third junction support, a first fastener, and a second fastener. The first junction support is spaced apart from the second junction support to define a first junction space. The second junction support is spaced apart from the third junction support to define a second junction space. The first fastener defines a first axis and extends through the first junction support, the second junction support, and the third junction support. The second fastener defines a second axis and extends through the first junction support, the second junction support, and the third junction support. And the first axis is spaced apart from the second axis. The portable barrier further includes a pedestal assembly including a plurality of legs that are movable with respect to each other. The plurality of legs includes a first leg and a second leg. The portable barrier additionally includes a cover assembly including a plurality of arms that are movable with respect to each other, the plurality of arms includes a first arm and a second arm, and a covering connected to the first arm and the second arm. Also, the portable barrier includes a supplemental component pivotally coupled to the junction assembly. The first strut pivots with respect to the junction assembly about the first axis during movement of the portable barrier between the storage mode and the protection mode. In addition, the second strut pivots with respect to the junction assembly about the first axis during movement of the portable barrier between the storage mode and the protection mode. And the junction assembly pivots with respect to the pedestal assembly about the first axis during movement of the portable barrier between the storage mode and the protection mode.

An adjustable folding cabana having a frame with legs is disclosed. A seat is supported on said frame. A front support member, a rear support member and an intermediate support member support a cabana fabric roof. The front support member is movable between a rear support position, an intermediate support position and a front support position. A guide rail is attached to the frame beneath said seat which has a front stop, an intermediate stop and a rear stop. Manipulating a control rod causes a cabana fabric hood to be fully extended when the rod is secured in the front stop, to be partially collapsed when the rod is secured in the intermediate stop, and to be fully collapsed when the rod is secured in the rear stop.

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.
