Foldedörsystem, spesielt til vognkasser

In the use of folding doors, it is possible to work with broad, crossbar-free access openings for various types of box vans with non-fixed frame parts, without broad and heavy swing- or sliding-doors being required. Such a folding door can typically consist of three hinged-together door wings which with moderate breadth can be folded together in a zigzag manner. However, this in itself requires that the door wings are hinged-together in a precise manner and are of a relatively strong and heavy configuration. With the invention, a lightweight configuration is made possible, in that the wings are hinged together with a certain degree of axial play, but on the other hand are provided with individual hand-lever means which make it possible to raise the wings to the correct closed position. There is thus no demand that the innermost wing must be able to support outer wings at the correct closing level, and a locking of the wings in the closed position can be achieved in a simple manner as a result of the raising itself.
