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

A sliding connecting member for a shelter framework includes a sliding connecting member having a lever connected to a cam. When pulled or rotated, the lever pulls out a locking pin from an aperture in a leg member. In this respect, releasing the locking mechanism allows the sliding connecting member to slide along the leg member and the framework can be folded or unfolded.

A collapsible shelter having a folding frame assembly, in which a plurality of leg assemblies are disposed at the corners. A central drive mechanism is disposed at a center of the perimeter, and a framework of a plurality of actuation members operatively coupled to the central drive mechanism and to the leg assemblies. The actuation members are structured and configured to move the leg assemblies towards and away from the central drive mechanism; and a canopy supported on the folding frame assembly. The central drive mechanism is configured to operate to simultaneously actuate the plurality of actuation members to move the leg assemblies in synchronization, thereby to expand and collapse the folding frame assembly in unison.

A universal hub adapter for a portable display frame assembly, the hub adapter being configured to mount to an outer surface of a display hub of the frame assembly. The universal hub adapter is configured to adapt the display hub of the frame assembly between the mounting of a first graphics system including a plurality of stretched fabric panels and a second graphics system including a channeled sub-frame for mounting a larger fabric panel. The universal hub adapter can include a faceplate having a substantially planar outer surface and a concave inner surface configured to mate with the convex outer surface of the display hub and a threaded post having a threaded portion, a securement plate, a button shaft, and a button head, the threaded portion configured to pass through an aperture of the faceplate and couple to the display hub, such that the securement plate abuts up against the faceplate thereby securing the faceplate to the display hub, the button shaft and button head configured to operably couple to one of a stretched fabric panel or a sub-frame assembly.

A tent support includes a plurality upright rods, a top module provided at a center of a top of the tent support, a plurality of side rod assemblies each connected to every adjacent two of the upright rods, and a plurality of top rod assemblies connected to the side rod assemblies and the top module. At least one positioning hole is provided at a junction of two adjacent side walls of each upright rod. A sliding seat provided on each upright rod includes a positioning member which is selectively engaged in the positioning hole, a spring, a positioning pin and an outward protruding button therein. The tent support, as a whole, is simple in structure, easy to assemble, and stable in positioning.
