Folding door with two or more inherently rigid folding shutter elements with alternate element edges that do not bend out and element edges that bend out in alternation and operating device for the same

摘要

The gate (10) has a folding loading element (12B) comprising an element edge with a guiding unit (17) i.e. guiding carriage, for moving a gate element edge (13B), where the guiding unit is connected to a guiding rails (16A). The gate edge has a coupling point (2) for raising and lowering of the gate edge. A displacement unit (7) i.e. two-arm lever (4), is arranged between the coupling point and the guiding unit for displacing the coupling point with respect to the guiding unit during the beginning of opening phase of the gate and during the end of closing phase of the gate.
