A tent with hubs positioned on the outer circumference of the tent, wherein the hub includes a plurality of pin rings that are configured to independently rotate at offset positions along a rotational axis to incrementally open and close the tent.

A portable room includes a number of sides, where a first side of the number of sides includes a first door, a second side of the number of sides includes a port, and the second side is adjacent to the first side. The portable room also includes a roof attached to the number of sides. The portable room further includes a number of pockets integrated with the roof, where each pocket is configured for receiving a filter.

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.

An integral tent structure and system that, through the use of flexible and specifically configured rib elements, along with selectively placed restraining elements to position and hold sections of the configured rib elements in proximity to each other, allows for easy folding, collapsing, storage, transportation, and then equally easy unfolding, assembly, and usage of the tent, is disclosed. The rib elements are designed to, with minimal directional force, fold, and collapse into a compact, readily storable configuration. The tent cover of the tent structure incorporates specifically placed connection and securing elements to provide means for securing the folded tent structure in the folded configuration. Because the rib elements are folded or collapsed with a resistive or expanding spring force, upon release of the securing elements, the integral tent structure automatically unfolds into the normal operative shape and configuration with little to no effort.

A tent includes a domed-shaped modular frame and a tent cover attachable to the frame and having a door, a transparent top, and rain cover. The rain cover also has a transparent top. A shield is selectively positioned on the interior of the tent cover to cover the transparent top. The transparent top of the tent cover and rain cover are resistant to ultraviolet radiation.
