(57) 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.
