Abstract
A stowable, load-bearing apparatus is disclosed having at least two bi-stable strips. Each of the bi-stable strips is alternatable between a stable, extended conformation having longitudinal linearity and lateral curvature and a coiled conformation having longitudinal curvature and lateral linearity. The two bi-stable strips are intercoiled when in the coiled conformation, have opposing lateral curvature relative to one another when in the extended conformation, and when extended are directed into a load-bearing alignment by a structural alignment member.
