ABSTRACT:
A multipurpose collapsible structure which may be used, for example, as a display stand or as a storage rack. The structure comprises four rectangular frames 2, 3, 4 and 5, defining a rectangular enclosure. The two opposite upright frames 2 and 4 have outwardly projecting bracket 12 which slide over the upper long sides of the other frames. The upright frames are pivoted at their bases enabling the structure to be collapsed, firstly to an oblique structure and then to a substantially flat state.
