[received by the International Bureau on 18 January 1994 (18.01.94); original claims 5 and 6 amended; original claim 9 cancelled; remaining claims unchanged (2 pages)]

1) Device for the accomplishment of an armoured roller blind which can be applied to windows and in the rooms of other premises, characterized

J by the inclusion of a metal slat with wide windows (Fig. 1, 2 N. 1)

5 strengthened in its inner cavity (5) by a steel frame (Fig. 3, 4 N. 1, 7, 9), a slat linked by head pins (14, 15) to special runner guides (Fig. 3, 5, 6 N. 17, 24) fixed with screws (25) to the lateral walls and having inside toothed rods (20) which stop the sliding of every single slat (19 in the wanted position.

10 2) Metal slat (Fig. l , 2, 3 N. 1) according to claim N. 1 , characterized by the fact that its particular profile made up by a central body (5) with a long superior neck (2) which ends as a hook (3) to join the hook (4) of the slat (1) above in the cavity of which it finds full reception, allows wide horizontal windows (Fig. 2 N. 2) and the insertion of a steel frame (Fig.

15 3, 4 N. 7, 9) in the central part (5).

3) Device according to claim N. 1, characterized by the fact that each slat (1) receives in its cavity (5) a steel tube of the same dimension (7) with a round hole (8) where a cut-proof steel round (Fig. 3, 4 N. 9) is inserted, the hole is threaded in the two ends for the screwing of the coupling pins

20 (14, 15) of the slats (1) to the lateral runner guides (17, 24).

4) Device according to claim 1, characterized by the fact that the first inferior slat contacting the treshold, has inserted a metal profile (Fig.3, 4 N. 10) which occupies the whole groove (6) of the slat (1) and it incorporates with an expansion outside used as plinth, the 25 hook ending part as (4) of the slat.

5) Device according to claim N. 1, characterized by the fact that each runner guide totally inserted in the lateral wall (Fig. 3, 5 N. 17) has in the inner back part a semicircular groove (19) which serves to contain a toothed cylindrical rod (Fig. 3 N. 20, 21) used as bolt to stop the stroke of

30 every single pin (14), has also a seat to place fixing screws (25) of the runner guide (17) to the wall.

6) Device according to claim N. 1, characterized by the fact that each runner guide for the installing inside the already exsisting common "U" type runner guides (Fig. 3, 6 N. 24) has in the inner front part a special

35 housing (19) to contain a toothed cylindrical rod (Fig. 3 N. 20, 21) used as bolt to stop the stroke of every single pin (15), it has also two outer fins to place the fixing screw (25) to the wall. 7) Device according to claim N. 1, characterized by the fact that each runner guide (Fig. 3 N. 17, 24) is equipped with a cylindrical rod (Fig. 3 N. 20) with a series of teeth (21) spaced out between them in comspondence to the position of the coupling pins (14, 15) which are used to stop the sliding of the mentioned pins (14, 15) inside the runner guides (17, 24).

8) Device according to claim N. 1, characterized by the fact that each slat (1) has in its ends a metal plug (Fig. 3, 4 N. 12) used for the fixing of the armouring tube (7) and the regular alignment of the slats (1), the plug is blocked inside the slat (1) by the neck (16) of the pins (14, 15).
