A tick-preventing multi-function-latch-pulley-handle and multi-function-latch-pulley-wheel popup comprises four-way circular roof intersector, foldable roof trusses, foldable side trusses, four upper corner intersectors and four lower corner intersectors each being able to be adjusted up and down, four automatic rounded-head see-saw post locks and four see-saw-post-lock springs respectively attached to the four lower corner intersectors for locking and unlocking upper corner intersectors, four multi-function latch-pulley-handles respectively and pivotably attached to the four upper corner intersectors for functioning as latches to wrap on the side trusses to lock the popup when folded and for also functioning as pulleys to wrap cables thereon and for also functioning as handles to unfold the popup, four upper octagonal posts, four multi-function post-centering water-discharging tick-preventing braces respectively attached to the four upper octagonal posts, tick-preventing downward teeth and water-discharging recesses, respectively molded to the four multi-function post-centering water-discharging tick-preventing braces for preventing ticks from entering the popup posts and allowing water drainage to protect pets and other occupants, post-height-adjusting tapered holes respectively inserted into four lower octagonal posts, wheel chassis respectively attached to the four lower octagonal posts, and multi-function latch-pulley-wheel rotatably attached to the wheel chassis for functioning as latches to hook cables thereon and for also functioning as pulleys to wrap cables thereon to tension the popup canopy and for also functioning as wheels to roll the popup along the ground.

A collapsible canopy has a collapsible frame and a canopy cover supported by the collapsible frame. In some configurations, the frame includes telescopic legs having three or more stages. An automatic lock release is carried by one of the legs and automatically releases a lock between two other of the legs. A relative inner leg can include a cap having a resilient portion that contacts an inner surface of a relative outer leg to increase a lateral rigidity of the leg assembly. At least one of the eave cross members can have an end portion having an abutting extension that contacts an adjacent cross member to limit lateral deflection of the eave. The abutting extension can be positioned between eave cross members that incorporate a bracket for supporting a center support that extends from the eave toward a center or interior of the canopy.

A frame for a shelter including at least four legs and at least four arch rails, wherein the legs and/or arch rails are preferably coupled together with rib members scissor-type coupled together and wherein the shelter is expandable and collapsible upon the arch rails being rotated relative to the legs such that angles greater than 90? and less than 90? can be formed (i) between the first leg and first arch rail, (ii) between the second leg and second arch rail, (iii) between the third leg and third arch rail, and (iv) between the fourth leg and fourth arch rail, and wherein angles less than 180? and greater than 180? can be formed (i) between the first arch rail and the third arch rail and (ii) between the second arch rail and the fourth arch rail.

Apparatus for use in isolating a subject, the apparatus including a frame movable between collapsed and erected configurations, a body supported by the frame, wherein in the erected configuration, the body defines an internal volume for containing a subject to thereby substantially isolate the subject from a surrounding environment and a door actuator supported by the frame for moving a door between open and closed positions to thereby provide access to the internal volume.

DE 86 22 844 01 discloses a tent having a carrying framework and a tarpaulin arranged thereon, wherein the carrying framework is formed by a scissor type system of rods having the tarpaulin arranged thereon.

Passageway including a section that is extendable and retractable, the section including frame, slide track assemblies, and scissor bar assembly. The frame includes upright members on a first side of the frame. The slide track assemblies are disposed proximately to the upright members. Each of the slide track assemblies includes a slide track and a slide block. The slide track has a cavity and a channel. The slide block can ascend, descend, and rotate within the cavity. The slide block includes a guide block that extends from the slide block through the channel. The scissor bar assembly is secured to the upright members and slide blocks of the slide track assemblies such that the upright members are enabled to extend and retract with respect to each other along an arcuate path, wherein the guide block limits rotation of the slide block to rotation of the guide block within the channel.

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.

Passageway including a section that is extendable and retractable, the section including a frame, slide track assemblies, and scissor bar assembly. The frame has upright members. The slide track assemblies are disposed proximately to respective upright members. Each of the slide track assemblies includes a slide track and slide block. The slide track has a cavity and channel. The slide block is configured to ascend, descend, and rotate within the cavity. The slide block includes a guide block that extends from the slide block at least partially through the channel. The scissor bar assembly is secured to the upright members and slide track assemblies such that the upright members are enabled to extend and retract with respect to each other along at least one arcuate path, wherein the guide block limits rotation of the slide block within the slide track to rotation of the guide block within the channel.
