Abstract
Abstract Two sliding doors or window sashes are supported on tracks of two rockers longitudinally juxtaposed on the bottom member of the door or window frame and each carrying two parallel tracks, the two pairs of tracks on respective rockers being aligned when both rockers are in an opening or in a closing position, and only one track of one rocker being aligned with one track of the other rocker when the rockers are in the opening and closing position respectively, whereby the doors or window sashes may both extend in the plane of the frame to obstruct the same or be practically coextensive in the direction of their sliding movement and offset transversely of this direction.
