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.
