PCT No. PCT/NL81/00011 Sec. 371 Date Dec. 4, 1981 Sec. 102(e) Date Dec. 4, 1981 PCT Filed Apr. 14, 1981 PCT Pub. No. WO81/03043 PCT Pub. Date Oct. 29, 1981.A folding wall being composed of modules and substantially comprising a double row of panels foldable in zigzag fashion by means of hinges, wherein at least two panels being in opposite positions in the rows are pivotally interconnected by a coupling piece having two relatively spaced supporting members, while two blades of resilient material slidable between two supporting members are each fastened to an inner side of a panel, said resilient blades will cause an inwardly directed force upon the panels when the wall is drawn out, so moving these panels into a parallel position, and wherein a lever is connected at a distance from the supporting members by means of a hinge with the coupling piece, so when folding the wall, said lever is adapted to exert a pressure on the free ends of the resilient blades, causing an outwardly directed force upon the associated panels so that the zigzag folding of the wall is facilitated. |
