ABSTRACT:
Structure for maintaining a sliding window sash at an intended position with respect to a frame within which the sash moves. The structure serves to retain the sash at a position along an axis generally perpendicular to a plane defined by the window frame. An inwardly facing surface of the frame has formed therein an elongated trough which extends generally parallel to a direction of intended sliding movement of the sash. A blade is mounted within a cavity in the sash and disposed for pivotal movement between a first position, wherein the blade is retracted within an outwardly facing surface of the sash, and a second position, wherein the blade is extended through the outwardly facing surface of the sash into the trough defined within the inwardly facing surface of the frame. The blade is normally biased to the second position, but it can volitionally be retracted to the first position to enable tilting inward or removal of the sash from the window frame.
