Abstract: A foldable, deployable framework for a structure has a lower hub having a first central axis, sets of tracks, masts, and rafters connected pivotally to the lower hub, to one another, and to an upper hub in a manner that allows the framework to be folded into one, two or three small packages, and to be deployed into a structural frame supporting floors, walls, and roof for an enclosed structure. In different versions folding and deployment is accomplished in a different way. Structures based on the framework can be made for many and varied purposes.

Abstract: Compacting, fully enclosed, floored combination multi-antechamber and ramp system for emergency and civil defense use providing, when expanded, means of ingress and egress for the general population including the infected, wounded and handicapped to and from buildings or other folding structures via portals to which its adapter may be securely attached or retrofit while passing through a series of two or more antechambers so as to prevent spreading contamination and allow for various decontamination protocols to be conducted in separate chambers. Compacting is achieved by modularity in some embodiments, and folding in other embodiments, in both framed and panel versions, providing important advantages for transport, pre-positioning, storage, and warehousing.
