ABSTRACT:
A pivotable and slidable window assembly includes one or more sashes slidable in parallel, coplanar horizontal tracks. Each sash carries a pair of pivot members extending in opposite directions from the sash to define a pivot axis for swinging the sash out of its usual sliding plane for cleaning or the like of both sides of the sash. Each pivot member is slidably received in a respective one of the tracks, and each includes a foot extending in the plane of sliding movement of the sash and perpendicular to the pivot axis. Each track includes an opening to receive the foot of a respective pivot member when the sash is pivoted for cleaning. Upon pivoting of the sash and movement of the feet into the respective openings, contact between the feet and the openings stabilizes the sash preventing further and unwanted sliding of the sash in the tracks. Thus the sash cannot twist catercorner with respect to the tracks and is prevented from falling out while pivoted.
