Disclosed is a double-spliced foldable tent with central lifting and automatic opening and closing structure, including two groups of central tops, one group of middle frame and two groups of edge frames. Any group of edge frame and middle frame are connected by telescopic fork frame. Two groups of side inclined frames are arranged between a group of central top and middle frame. At least one group of side inclined frame is arranged between a group of central top and a group of edge frame. One group of central tops includes an upper top and a lower support locked or separated by spring pin. One group of side inclined frame includes a first inclined rod hinged on upper top at one end and a second inclined rod hinged on lower support at one end, of which the other end is hinged on the side wall of first inclined rod.

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 mobile automotive spray booth having a collapsible enclosure and a fire suppression system. The fire suppression system includes a control unit, a fire detection cable or cable assembly in communication with the control unit, and a fire extinguisher assembly in communication with the control unit. The fire detection cable or cable assembly extends across at least a portion of the collapsible enclosure, and is configured to detect a fire within the collapsible enclosure. The control unit is configured to activate the fire extinguisher assembly to extinguish the fire upon detection of the fire by the fire detection cable or cable assembly. The fire detection cable or cable assembly is configured to bend to allow the collapsible enclosure to collapse from an expanded configuration to a collapsed configuration without removal or disassembly of the fire detection cable or cable assembly.

A wheeled collapsible canopy with foldable support frame. The wheeled collapsible canopy includes at least two wheeled legs and also at least two non-wheeled legs. A protective cover covers the top of the collapsible canopy when the collapsible canopy is in a folded state. The protective cover extends only partially down the length of the folded support frame.

A rotary unlocking central lock device is adapted for a foldable tent. The rotary unlocking central lock device includes a top plate base, a lock rod, a lower plate base, and a rotary base. The rotary base is rotatably fit with the lower plate base. A lock rod latch mechanism is disposed between the rotary base and the lower plate base. A top portion of the lock rod is fixed with the top plate base. A bottom portion of the lock rod penetrates through the lower plate base to fit with the lock rod latch mechanism. Locking and unlocking of the lock rod and the lock rod latch mechanism can be realized by rotation of the rotary base.

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.

An articulating frame for a shelter includes a plurality of struts pivotally connected to each other to define a skeletal structure that is adapted to be articulated between a folded condition and an erected condition. The skeletal structure in the erected condition includes a segmented arch that defines an interior space. The skeletal structure is adapted to support an associated outer shell covering. The frame includes at least one double-scissor linkage segment including four of the plurality of struts. The four struts include: (i) first and second struts each with opposite inner and outer ends, the first and second struts bring pivotally connected to each other at a first pivot point located between their respective inner and outer ends; and, (ii) third and fourth struts each with opposite inner and outer ends, the third and fourth struts being pivotally connected to each other at a second pivot point located between their respective inner and outer ends. The inner end of the first strut is pivotally connected to the inner end of the third strut at a third pivot point and the inner end of the second strut is pivotally connected to the inner end of the fourth strut at a fourth pivot point such that a four-bar parallelogram accommodating linkage is defined by the four struts between the first pivot point, the second pivot point, the third pivot point, and the fourth pivot point.

A shelter system is shown and described. A hub for a shelter system is shown and described. A frame for a shelter system is shown and described. In one embodiment, the shelter system includes a frame, a cover and a hub. The frame may be collapsible. The cover is configured to fit with the frame. The hub may include a receiver slot, a receiver sleeve and an attachment projection. The result is a shelter system with reduced set up time, effort and requirements and improved strength and ease of use. The inventions may also be considered a shelter kit and/or a shelter and hub method.

A portable room is presented. The portable room includes multiple sides and a roof attached to the multiple sides. The portable room also includes multiple pockets integrated with the roof. Each pocket is configured to receive an insert, such as an air filter. The portable room is attachable to a structure, such as a portable shelter.
