Hinge device for inclined tilting type windows with external cover rails

摘要

In a hinge device for inclined tiltable windows with external overlapping cover rails, the base plate of the main frame supports through a pair of pivotable links an intermediate member which is movable in a parallelogramlike-or pantographlike-manner and itself carries a pivot pin on which the sash base plate of the hinge device is journalled. The rotation of said base plate about the pivot pin is co-ordinated with the movement of the intermediate member by way of a coupling link that through pivot pins is connected with the sash base plate and the pivotable link adjacent the coupling link, respectively. The coupling link makes it possible in a simple and cheap manner to reliably controlling the hing parts during the full tilting of the sash in both directions.
