<p>The invention concerns a folding door with several pairs (2, 3) of panels and fitted with a simple, functional and space-saving device for opening out the individual pairs (2, 3) of panels. Fixed to the neighbouring panels (2a, 3a) of two pairs (2, 3) of panels are entrainment pieces (7) in whose field of traverse lie the arms (8a) of two-armed levers (8). The other arms (8b) of the levers (8) extend to the nearest respective panel (2a) and (3a) so that, when one of the panels (e.g. 2a) pivots, from a certain point in the pivoting motion a turning moment is generated which acts via the entrainment piece (7), the lever arm (8a) and the lever arm (8b) on the neighbouring panel (3a) in the opening direction.</p> |
