Appl. No.:

7/421344

Kenneth K. Schweiss - Wyoming PA

Assignee:

Exeter Architectural Products, Inc. - Wyoming PA

International Classification:

E06B 368

US Classification:

49 56

Abstract:

A window guard screen and frame assembly installable on the jamb of a building window to prevent unauthorized access therethrough. The assembly screen is fabricated from a single sheet of metal having folded-in margins to define channel-like upper and lower end branches and right and left side branches bordering a planar field that is perforated in a predetermined pattern to admit light and air. The planar frame is dimensioned to overlie or nest within the window jamb and is secured to the walls or face of the jamb by adjustable brackets. Integral with the inner surface of the frame and surrounding the opening therein is a slideway socket for receiving the screen, the socket being defined by upper and lower end legs and right and left side legs. One side branch of the socketed screen is hinged at its extremities to the upper and lower end legs of the socket by hinge pins slidable in slots formed in these legs whereby the screen is horizontally slidable from a security mode position in which it is confined to the socket and the window is guarded, to an access mode position in which the screen is free to swing out from the frame opening to permit one to exit through the then unguarded window. A releasable latch is provided which engages the other side branch of the screen and is accessible only from the building inside to lock the socketed screen in its security mode position.

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.
