Abstract: A window crank assembly includes a stationarily supported cable drum having a core; a housing accommodating the cable drum and having a slot; a cable slung about the core and passing through the slot and being connected to the window pane; a drive for rotating the core, whereby a pulling force is exerted on the cable; a cable conduit accommodating a length portion of the cable as well as fittings supporting opposite ends of the cable conduit. At least one of the fittings is supported on a guide segment member in the vicinity of the cable drum at a predetermined distance from the core. This fitting is swingably arranged on the guide segment member for motion in a plane which is parallel to the slot provided in the housing.

Abstract: A window crank assembly includes a guide rail mounted substantially parallel to the direction of motion of a window pane to be raised and lowered by the crank assembly; a sled mounted on the guide rail for back-and-forth travel thereon; a drive cable attached to the sled for moving the sled on the guide rail; a plug-and-socket joint for supporting a lower end of the guide rail for a pivotal motion about a lower foot point in a direction substantially perpendicular to the plane of the window pane; and a support for engaging the guide rail at a location thereof spaced from the lower end. The support defines a pivotal axis extending substantially perpendicularly to the plane of the window pane. The support holds the guide rail displaceably about the pivotal axis and shiftably parallel thereto prior to establishing connection of the guide rail with the plug-and-socket joint.
