ABSTRACT:
A collapsable, articulated wall structure is formed from pivotally interconnected links. In an erected configuration, the wall has a generally planar face which is suitable for hanging display posters. In a collapsed configuration, the wall folds into a compact bundle of generally parallel links. The wall is comprised of a plurality of rectangular parallelpiped sections. Each section has a first plurality of pivots in the four corners defining a face of the section and a second plurality of pivots on the other four corners of the section. The first plurality of pivots is connected with the second plurality of pivots by a plurality of side links which are pivotally interconnected in an X-shaped arrangement. Displaced slightly inward from the face plane is a face pivot which is connected to the first plurality of pivots by four face links. The section is releasably locked in its erected configuration by a locking link. The locking link is pivotally connected at one end to one of the face links and at its other end to one of the second plurality of pivots.
