Abstract: front page image
(EN)A folding wall being composed of modules and substantially comprising a double row of panels (1) 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 (4) having two relatively spaced supporting members (13), whilst two blades (11) of resilient material slidable between two supporting members (13) are each fastened to an inner side of a panel, said resilient blades (11) 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 (15) is connected at a distance from the supporting members (13) by means of a hinge (16) with the coupling piece (4), so when folding the wall, said lever (15) is adapted to exert a pressure on the free ends of the resilient blades (11), causing an outwardly directed force upon the associated panels (1) so that the zigzag folding of the wall is facilitated.
(FR)Paroi pliable composee de modules et comprenant sensiblement une double rangee de panneaux (1) pliables en zigzag au moyen de charnieres, dans laquelle au moins deux panneaux occupant des positions opposees dans la rangee sont relies entre eux de maniere pivotante par une piece de couplage (4) possedant deux organes de support (13) relativement espaces, tandis que deux lames (11) d"un materiau elastique pouvant glisser entre deux organes de support (13) sont fixees chacune a un cote interieur d"un panneau, ce lames elastiques (11) exercant une force dirigee vers l"interieur sur les panneaux lorsque la paroi est depliee, ce qui a pour effet de faire pivoter les panneaux dans une position parallele, un levier (15) etant relie a une certaine distance des organes (13) de support a la piece de couplage (4) au moyen d"une charniere (16), de sorte que lorsque la paroi est repliee, le levier (15) exerce une pression sur les extremites libres des lames elastiques (11), ce qui a pour effet d"exercer une force dirigee vers l"exterieur sur les panneaux associes (1) de maniere a faciliter le pliage en zigzag de la paroi.
