<p>Collapsible staging formed from modules each having end frames (1, 2) and side frames (3), the side frames incorporating vertical hinges (5) allowing the side frames to be collapsed in a concertina fashion as the end frames (1, 2) are moved toward one another, so that the folded framework lies in a flat "sandwich" configuration. The frames support a platform (8, 9) which may be detached, or alternatively hinged to one end frame and also folded in a concertina fashion. Alternative configurations provide folding stairs and ramps.</p> |
