Abstract:
A device for pivotable and slidable suspension of sheets, said device comprising:an upper and a lower rail, which are arranged in parallel with each other and which each have, transversely of their longitudinal direction, a hollow section with a longitudinal slot defined by inwardly projecting flanges on the side facing the other rail, and a pair of upper and a pair of lower fixing elements on each of the sheets, said fixing elements being, via the slots, in horizontal engagement with the rails, the lower fixing elements having in their lower-most portion a spherical part which rests against a planar sliding surface in the section of the lower rail wherein both the lower and the upper fixing elements prevent any vertical engagement between the fixing elements and the rails in the area of the slots and allow relative vertical motion between the rails and fixing elements having elongated cylindrical portions extending in the vertical direction through the slot in each rail, the cylindrical portions extending in the vertical direction allowing relative vertical motion between said upper and lower rails and said upper and lower fixing elements respectively, and the diameters of the cylindrical portions being slightly smaller than the width of each slot to absorb horizontal forces in the contact area between the cylindrical portions and the flanges defining the slots, wherein said rail sections at predefined opening positions have opening apertures on at least one vertical side of the rails for passage of one first vertical pair of upper and lower fixing elements when opening the sheets, said aperture being closable by a telescoping section which in a closed position transmits horizontal forces from the sheets to the fixing elements, and means for locking of a second vertical pair of upper and lower fixing elements in a position along the rail when pivoting the sheet around said second pair of fixing elements during opening of the sheets.
