<p>This invention is represented by a casing or a fixture in which is fitted, at least on one wing of the fixture, a frame consisting of openable or extensible slides; these slides consist of movable parts suited to go from a closing position, in which the series of slides form a frame enclosing a safety grate, to an opening position in which these slides allow the grate to come out from the fixture profile and finally close the windows/door opening. The invention intends to apply to the wing of a fixture, a frame consisting of channel irons, duly shaped, placed along the perimeter of the wing; among these channels is fitted a metallic protection grate. The structural shapes, constituting the frame wedge placed just next to the hinging side of the wing, can be opened and go into contact respectively with the windowsill and the upper edge of a window opening, in such a way as to create a couple of slides along which the grate representing the armour plating element can slide in order to close the window opening. <IMAGE></p> |
