  • Patent number: 6553715
    Abstract: A device for turnable and slidable suspension of sheet elements including a coupling member (100) which is supported by a rail and has an elongate groove (101) in essentially the same direction as the rail, and a coupling pin which is non-rotationally arranged on the sheet element coinciding with its pivot axis and which is slidable in the groove of the coupling member. The groove of the coupling member has an inclined lateral cam surface (102) and at least one essentially part-circular recess (104), with a center axis (E) which is essentially parallel to the pivot axis of the sheet element, in the inclined lateral surface (102).

  • Patent number: 6487753
    Abstract: A device for pivotable and slidable suspension of sheets, such as window-panes for glazed verandas or balconies. The device has an upper and a lower rail, which are arranged in parallel with each other. The rails have transversely of their longitudinal direction a hollow section with a longitudinal slot on the side facing the other rail. On each of the sheets, an upper and a lower fixing element are arranged, which via the slots engage the rails. The lower fixing element has in its lowermost portion a spherical part which rests against a sliding surface in the lower rail section to enable both a sliding and a pivoting motion. Both the upper and the lower fixing element are cylindrical in the portion which extends through the slot in each rail.
