ABSTRACT:
The subject of this invention is a security window bar system containing three types of elements. The first type comprises a plurality of vertical bars, the second type comprises at least two horizontal metal plates, and the third a plurality of right angular, generally L-shaped brackets or fasteners. The vertical bars are held in place by the horizontal crossbars which have therethrough spaced openings which the vertical bars extend. Opposite ends of the horizontal crossbars are fastened to opposite sides of the window frame by the L-shaped fasteners, each of which has one leg fastened to an adjacent end of a crossbar, and the opposite leg fastened to the window framework by a one-way screw. The result is a simple, inexpensive, and easy to install window bar grid system that prevents unwanted intruders from entering the structure.
