Abstract: A foldable structure which can be used as the basis for a wide variety of articles, such as furniture, office equipment, freight containers and portable buildings, is foldable between a generally flat form and an erected, three-dimensional form. A first pair of opposed frame units (10,11) are connected by at least one further frame unit (12), which is hingedly attached to one (11) of the pair of frame units and is hingedly and slidably attached to the other (10) of the pair of frame units, for example by means of swivel cleats (13). Further components are connected to one or both of the pair of frame units (10,11) so that such further components can be disposed in a folded-flat position adjacent to said pair of frame units (10,11) when the latter are in their collapsed state and can be disposed in a second, ready-for-use position in planes at an angle to the planes containing the frame units to which they are attached.

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.
