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.

Abstract: A collapsible security grille is provided comprising two conventional face-to-face sets of rigid grille bars (2, 9) pivotally interconnected at their intersections, wherein all the pivotal connectors (4) are uniformly and non-adjustably spaced apart along their respective grille bars in one said sets, but are free, as far as the second set is concerned, to undergo small sliding displacements along the grille bars of that set. In this way the stresses that ordinarily lead to jamming, jerky action and noise are automatically compensated at the point and instant of their origin. It is preferred that the pivotal connectors around the periphery of the second set are likewise non-adjustably spaced apart, so that every such connector at a grille bar meeting point (6) (as distinct from a crossing point 8) is spaced from both of the two next adjacent crossing-point connectors (8).
