Abstract
A window assembly includes a main outer support frame supporting at least one movable rectangular sash frame enclosing an insulated glass panel. The sash frame is supported for vertical or horizontal movement between open and closed positions, and an interlocking system is effective to lock adjacent overlapping sash frame members. The interlocking system includes an angular metal clip member mounted on one sash frame member and having a flange projecting into a slot within the adjacent sash frame member. A pair of clip members are located under the tilt latches on single and double hung window assemblies and are secured to a vertical sash frame member on a horizontal sliding window assembly. The interlocking system responds to a substantial positive or negative wind load or such a wind load after an impact which breaks a glass panel, to limit deflection and prevent permanent deformation or release of the movable sash frame.
