PCT No. PCT/DE89/00385 Sec. 371 Date May 25, 1990 Sec. 102(e) Date May 25, 1990 PCT Filed Jun. 13, 1989 PCT Pub. No. WO90/01099 PCT Pub. Date Feb. 8, 1990.A folding door has plural pairs of panels and the panels of each pair are pivotally connected to one another via hinges defining vertical pivot axes. For any two neighboring pairs, a first panel of one pair and an adjacent second panel of the other pair are articulated to a carrier movable along a horizontal guide rail. At least each first panel supports an elongated actuating element having a projecting portion which overlies the adjacent second panel in the closed position of the door. Every carrier supports a two-armed lever which is rotatable on an axis paralleling the pivot axes defined by the hinges. In the closed position of the door, a first arm of each lever, is located in the path which the projecting portion of the respective actuating element follows during opening of the door while the second arm abuts the respective second panel. When one pair of panels is folded in order to open the door, the projecting portion of the corresponding actuating element pushes against the first arm of the associated two-armed lever. This causes the second arm of the lever to push against the second panel of the pair of panels adjoining the folded pair thereby facilitating folding the adjoining pair. |
