Abstract

A window guard screen and frame assembly installable on the jamb of a building window to prevent unauthorized access thereto. The screen is fabricated of a metal sheet whose margins are folded in to define channel-like end and side branches bordering a planar field perforated to admit light and air. The frame is dimensioned to overlie or nest within the window jamb and is secured thereto. Integral with the inner surface of the frame and bordering the opening therein is a slideway socket for receiving the screen, the socket being defined by end and side legs which complement the branches of the screen. Hinge pins are mounted on the end legs of the slideway socket adjacent one side leg, the pins extending through elongated slots formed in the corresponding end branches of the screen whereby the screen is slidable to an extent limited by the slots from a security mode position in which the screen is confined to the socket and the window is guarded, to an access mode position in which the screen is free to swing on the hinge pins out from the frame opening to permit one to exit through the then unguarded window. A releasable latch is mounted on the other side leg of the socket to engage the corresponding side branch of the screen to lock the socketed screen in its security mode position. When released, the latch permits the screen, which is spring loaded, to slide to its access mode position.
