Abstract: The retractable screen retention system is a guiding device for retractable screens that is sturdy, secured, and does not displace easily. To accomplish this, the system includes a track assembly, a guiding rail, and a sliding assembly. The sliding assembly further includes a retention housing and a weight bar. The design and components of the retention housing allows for movement of the weight bar and the retractable screen and yet keeps them retained in the system. Furthermore, the arrangement of the sliding assembly is designed to be flexible and doesn't allow it to come out of the track during deflective motions such as due to wind or some other physical impact. Thus, the system provides a track assembly with a guiding channel for the retractable screen that prevents the displacement of the retractable screen from the track while providing flexibility.

Abstract: Systems and methods for deployment, storage, transport of expandable room dividers. The systems may include a frame configured to lock room divider panels compactly stacked against each other for storage and transport. The frame may retain a non-releasable panel and maintain it vertically upright. That panel may be hinged along a non-retained vertical edge to a closest of a plurality of panels movable with respect to the non-releasable panel. The plurality's panels are serially hinged together, accordion-like, along vertical edges. Hinge angles between adjacent stacked panels are approximately zero degrees.
