ABSTRACT:
Hardware for the closure of a door or window which is constructionally simple and functionally reliable, permitting movement of the closure out of the frame to a parallel position and allowing horizontal shifting in this position. Lower supporting arms are pivotally mounted on the closure and two traveling carriages are associated with the supporting arms and with an associated bearing block at the side of the closure. The carriages are designed in mirror-image relationship, so that the carriages are movable in opposite directions by means of a differential coupling gear.
