ABSTRACT:
A system of articulated planes foldable from a planar configuration to a compact low-volume form. The structure is formed of a series of hinged planes, the planes having inwardly hinged joints at one edge and outwardly hinged joints at an opposite edge, such that the series of planes can be folded in the manner of the sides of an accordion bellows. A plurality of such articulated planes can be arranged in parallel fashion, such that the folds of the second series mesh with those of the first, the folds of the third series mesh with those of the second, etc. The hinges joining the planes are thus positioned in aligned rows transverse to the extent of the plane series and are dimensioned to accommodate the folding action. The hinges of each outside series have a broader span than the adjacent inner one. The inwardly hinge joint of a row are additionally hinged to alternate arms of a pantographic framework, the framework having a pair of cross arms for each series of planes, and a separate pantograhic framework provided for each row of inwardly hinged joints.
