(57) This invention proposes a casing in which at least one side of a shutter (7) is fitted
with a support frame (3) for a sliding armour plate (1) made in such a way as to move
from a close position - where it remains contained into the said frame - to an open
position where, with the shutters (7) open, it comes out from the said frame (3),
and finally closes the window/door opening.
The said armour plate (1) can consist, for example, of a metal grate or armour-plating
bars welded to an armour-plating case in which at least one - either upper or lower
- edge is slide-mounted on the support frame by means of telescopic slides, e.g. ball-bearing
slide type.
Ultimately, according to this invention, a frame (3) in which an armour plate (1)
slides is applied to or fitted into the door/window frame shutters; the said case,
while the shutters are open, can come out and close the window/door opening or remain
held into the said case and hidden by the shutter itself.
In compliance with a preferred embodiment of the invention, this support frame (3)
can be fitted with an additional panel of the shutter, in such a way as to create
a double-sided shutter, inside of which both the case and the armour plate (1) are
hidden, if the said armour plate, while the shutters are open, is not pulled out of
the case.
