A light, latticed, tubular structure collapsible to become substantially flat or thin, particularly for laying or exposing objects and for hanging the washing, comprises a collapsible trestle (5) including two trestle members (05, 05') hinged at the vertex (55, 55') and at least two draw stage members (4', 4''; 6', 6'', 7', 7'') hinged therebetween and each of them to the corresponding tubular rod of trestle member (05 or 05') of the trestle (5). The hinged vertex connection (55, 55') of the trestle members (05, 05') and the swingable connections (41, 61, 71) between such trestle members (05, 05') and said stage members (4', 4''; 6', 6''; 7', 7'') as well as the hinged connections (40, 60, 70) therebetween provide a collapsible openwork capable of being folded up substantially as a parallelogram. |
