Abstract
A friction window hinge comprises a frame plate (15) for attachment to the fixed window frame (12), a vent plate (27) for attachment to the movable window vent (11), and a separate curved link (19) which extends between the plates and is slideably engageable with correspondingly curved guide tracks (17, 28) on both of the plates. In the open position the curved link (19) is extended between the plates (15, 27) to support the window vent, while in the closed position the plates are brought into overlying relation with the link retracted between them. The arrangement allows the vent to be swung to the fully open position without the hinged side of the vent significantly obstmcting access through the aperture in the fixed frame.
Claims18
A window hinge comprising a first guide having means for attachment to a fixed window frame, a second guide having means for attachment to a movable window vent, and a link which is engageable with both said guides and is slidable relatively to each guide, wherein each guide is carried on a respective base plate which is substantially co-planar with the guide and extends laterally thereof, which base plates are substantially parallel to one another and move into overlying relationship to one another when the hinge is brought to its closed position.
