ABSTRACT:
In a family of collapsible structures, each collapsible structure has a collapsible beam. For each collapsible structure of the family of collapsible structures, the collapsible beam includes a plurality of curved strut pairs of the same length as the curved strut pairs as in every other collapsible structure of the family of collapsible strut pairs. The struts of each curved strut pair are pivotally connected to each other at points closer to the one end of the struts than the other end of the struts. Different collapsible structures of the family of collapsible structures have a different number of curved strut pairs than any other collapsible structure of the family of collapsible strut pairs.
