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.

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.

Abstract: A support system for landscape screens is disclosed in which the panels of an elevated or computer floor are provided with sockets which receive studs. The studs are mounted on tracks which, in turn, are secured to the lower side of the landscape screen. The tracks permit the studs to be located at various positions along the landscape screen so that the studs can be positioned within the sockets in the floor panels. The floor panel sockets are eccentrically located so that they can be located in a plurality of positions by properly orienting the panel within the floor system. Various height adjusting means are disclosed for adjusting the height of the studs, and in turn the screen above the floor surface. Further, various structures are illustrated for anchoring the tracks to the landscape screens.
