Retractable structures comprised of interlinked panels

DETAILED DESCRIPTION In accordance with the present invention, a retractable structure is presented that incorporates an additional useful feature.
I have discovered a way to construct such retractable structures whereby the links are themselves panel elements.
Thus, the structural members themselves form a continuous surface, leading to a more economical, structurally sound and cleaner design.
Such links can be assembled to form planer and three-dimensional structures.
In their planar embodiments, retractable structures according to this invention may be comprised exclusively of panels hinged together.
In their three-dimensional embodiments, whether conical, hemispherical or other shapes, panels are connected to one another via small hub elements.
This discovery represents a significant improvement over the earlier invention, and offers the promise of building of practical architectural structures with retractable features.
