SCALABLE AND PORTABLE POPUP WORKSITE SYSTEM
A scalable and portable popup worksite system for work that requires indoor or outdoor workspace isolation from the surrounding elements. In the preferred embodiments, the invention comprises a foldable frame structure, a cover retaining system, and a ventilation system. The frame structure comprises a plurality of foldable wall trusses connecting a plurality of upright telescopic posts transversely forming a wall frame structure and a closed loop geometric footprint, a plurality of foldable roof trusses connecting a centrally disposed roof connector assembly to either the telescopic posts or the wall trusses transversely forming the roof. The cover retaining system comprises a plurality of cover retaining assemblies, spring clips and spring clamps to secure roof and wall cover to the frame structure. The ventilation system comprises an enclosure that can utilize standard furnace air filters and existing air circulation devices. Multiple frame structures can be linked together to scale up workspace.
The present invention relates to a scalable and portable popup worksite system that can provide workspace isolation or separation from the surrounding elements. The present invention offers a system that can be quickly set up and dismantled, adjusted in height to accommodate height constrains, scaled up with multiple units and stowed away in compact and space-saving form.
BACKGROUND OF THE INVENTIONIn many worksites such as construction and renovation sites, it's inevitable that work activities generate airborne particles, such as saw dust, tile cutting dust, sanding dust, spray painting droplets, etc. The airborne nature of the particles creates difficulties to perform concurrent work activities and work waste cleanup, due to hard-to-control cross-contamination. For example, saw dust and tile cutting dust may contaminate un-dried painting surfaces, while spray painting droplets may contaminate existing finished surfaces. This creates the need for a temporary workspace, in which work waste is contained within the workspace, to prevent cross-contamination to surrounding elements. In other situations, there are needs to protect elements from surrounding airborne particles, such as protecting tools, furniture, un-dried painted parts, etc., from being contaminated by dusts or droplets.
While there are other portable worksites existing in the art, for example, patent Pub. No. US 2020/0230638 A1 and Pat. No. US 2010/0272915 A1, they are limited in the functions of quick and easy assembling/dissembling, and/or compact storage. Due to the temporary nature of the portable worksite, these create their limits. They are also limited in other factors demanded by a temporary worksite, specifically, in the scalability, where larger space is required, and/or the adjustability, where the worksite height must be adjusted to accommodate its external housing constrains.
There are many other portable frame structures existing in prior art in other fields, such as U.S. Pat. Nos. 9,482,026 B2, 7,520,290 B2, and 10,900,249 B2. However, they serve respective objectives in their fields but not for the scalable and portable worksite objectives.
Therefore, there is a strong need for an economical and portable worksite that can be quickly assembled and dissembled, can be easily adjusted in height, can be scaled up with multiple units, and can be stowed away in compact form when the worksite is not needed.
SUMMARY OF THE INVENTIONThe primary object of the present invention is to provide a foldable popup frame structure that can be quickly and easily assembled and dissembled, and in compact storage form.
The second object is to provide a roof and wall cover retaining system that can attach existing commercially available plastic sheeting and/or other fabrics to the frame structure, so as to cover the roof and walls to form an isolated workspace.
The other object is to provide capacity of height adjustment when setting up the frame structure, so that the frame structure's height can be adjusted to accommodate its exterior housing constrains, such as a ceiling limit imposed by a garage or a room in which the frame structure is being setup.
The other object is to provide capacity to scale up the workspace by linking multiple units of the frame structure.
The other object is to provide a ventilation system that can utilize a commercial standard furnace air filter to filter airborne particles or droplets, and force air circulation inside the worksite by an existing air circulation device such as a blower fan, or through ducting to other ventilation blowers, or by customization to utilize an existing bathroom exhaust fan and so on.

The plurality of slots on the roof cap connector 401 are matched and paired up with the plurality of slots on the slidable connector 403 to be connected to the roof trusses 300.
To pop up the roof, a user may push up the handle to lock the roof pole 405 in the roof cap connector 401 by guiding the twin-tip pin through the openings of the long vertical paths and the horizontal paths to the short vertical paths. The tubular shape of the roof pole 405 in the preferred embodiments is a cylinder. However, in some embodiments various tubular shapes may be used.
The second type roof truss 1300 may comprise an arm preferably having the same components and construction as the first or second arm of the second type wall truss 1200. On one end of the second type roof truss 1300, the end portion of the longitudinal member 201 projecting upward may be pivotally connected to the roof truss slot of the respective first T connector 1201, and the end portion of the longitudinal member 201 projecting downward may be pivotally connected to the roof truss slot of the respective second T connector 1202.
