With reference to the number references of the above mentioned figures, the safety blind according to the present invention, which has been generally indicated at the reference number 1, comprises a perimetrical construction 2 formed by aluminium section members 3 of different shapes and provided with abutment seals or gaskets.
The main feature of these section members is that they are provided with armoring foils 4 7 preferably made of steel or other high strength materials, which have been suitably fitted in seats or recesses 5 provided in the inside of said section members.
In particular, the seats 5 are arranged near that portion of the blind which is outwardly turned, as clearly shown in figure 1.
In another preferred embodiment it is possible to engage additional armoring foils also in seats provided near the portion of the blind facing inwardly.
The assembling of the above disclosed safety blind 1 in a suitable recess provided in the room wall, which also constitutes the housing of the window, involves the use of further aluminium section members 6 provided in their inside with armoring foils 4 which are suitably anchored to the top and bottom side walls of said recess and operate as a support for the above mentioned construction.
In particular, the construction 2 is provided with a plurality of side hinges 7 which allow the rotary movement for opening and closing the safety blind 1.
Said hinges 7, which are provided with pivot pins 8, which in turn are suitably locked so that can not be withdrawn, are connected to the perimetrical construction 2 by means of suitable connecting screws 9, while being anchored to the aluminium section members 6, arranged along a perimetrical or side wall of the above mentioned recess.
More specifically, the hinges 7 are anchored by connecting screws 10 to light alloy blocks 11, which are so designed as to present a L-shaped cross-section, provided inside said side section members 6.
A main feature of the latter section members 6 is that they are provided, in their inside, with additional light alloy compensating elements 12.
The latter are affixed to said blocks 10 engaged in steel plug members 13.
These plug or pin members 13 as is shown in figure 8 are introduced into the concrete wall by passing through false frames of L shape made of steel and suitably embedded in said concrete material by using safety affixing brackets.
Moreover, the above mentioned perimetrical construction 2 is provided, on the side surface opposite to that thereon there are provided the mentioned hinges, with a cremone bolt or handle 15, adapted to perform the opening and closing of the blind 1.
The perimetrical construction 2 constitutes the supporting element for a plurality of slates 16 made of aluminium.
Each slate 16 has the feature that it is provided in its inside with an armoring foil 17.
Moreover the subject safety blind can be constructed according to two preferred embodiments.
More specifically, a preferred embodiment provides that the above mentioned slates can be also arranged, in a partially superimposed relationship, with a fixed orientation, usually slanted at about 15° with respect to the vertical direction.
In particular, each slate 16 will be affixed, by means of two pairs of screws 18 engaged at its opposite ends 19 and 20, so as to provide an anchoring of said slate to the aluminium supporting element 21 which can be introduced into a seat 22 of the same section member, as is shown in figures 4 and 5.
In this connection it should be pointed out that the slates 16 are provided with inner cavities 40 in which can be engaged the armoring and reinforcing foils 41.
The second preferred embodiment of the present invention provides slates which can be arranged with a variable orientation.
In this embodiment, a shown in figures 6 and 7, each slate is affixed to the aforesaid foil 21 by means of a pin 23.
Said slates, accordingly can rotate with respect to this fulcrum, by performing a partial rotation through 45° with respect to the normal attitude which is tilted at 15°.
Thus, there is the possibility of allowing the passing through light to be filtered or caused to pass through in an adjustable amount through the thus arranged slates constituting the subject safety blind.
With reference to figure 10 there is herein shown a specifically designed aluminium slate 16 which is provided with an inner cavity 5 provided with inwardly projecting ribs 5' which operate to hold perfectly arranged and guided the armoring foils 17inside the mentioned cavities of the slate 16.
With reference now to figure 11, there is herein shown an armoring foil 16 affixed by means of screws 18 to a male shell 52 operating as an element for locking the above mentioned foil 16.
In particular the male shell 52 is applied by means of self threading screws 18 and a push fitting plate element.
Figure 11 also shows a wing section member 50 which is provided with cavities 51 in which can be engaged corresponding armoring foils.
The above mentioned wing section member 50 is moreover provided with a screw 54 for locking a female shell 53 in turn provided with a handling pin element.
Figure 11 shows furthermore a rod 55 which operates as a control element for the mentioned handling or driving pin.
Figure 12 illustrates, on the other hand, a movable wing section member 60 which is provided with cavities 4 in which can be engaged armoring foils.
Said movable-wing section member 60 is applied to an arm 61 by means of a screw 9 and is provided with a sealing gasket 62 which abuts against a further section member 63 provided with a seat for a seal or gasket 64 which, in turn, abuts in the inside against the movable-wing section member 60.
Between the two gaskets 62 and 64 there is defined a space 65 which is defined by seats 4, on the inside and outside, for housing corresponding armoring foils.
The thus made blind has the main feature that it is provided with section members adapted to house corresponding armoring foils which will reinforce said blind both in its inside and on its outside, in a perfectly continuous manner thereby providing said blind with a very high strength against possible tampering operations.
With continuous reference to figure 12,there is clearly shown herein a wall portion 66 to which there is fixedly connected a metal back frame 14 of substantially L shape.
In this metal backframe there is pressure fitted a plug element which, in particular is press engaged in a calibrated hole provided in said back-frame.
To said plug element 13 there is applied an extruded aluminium block 11 adapted to allow a hinge portion 14 to be locked to the wall 66.
Said extruded aluminium block is applied to the wall by means of a light alloy compensating element and a screw 68 so as to provide a perfect locking and affixing of the hinge to the wall.
The slates 16 are provided with housing seats 42 in which there are engaged gaskets or seals 43 which are provided with projecting lugs 44.
The latter, as they are arranged among the slates 16 of the blind, will shut off to the light the blind as desired by the user.
The above mentioned gaskets furthermore, as the blind slates are arranged in their closure positions; will also provide a great thermal and acoustical insulation.
From the above disclosure it should be apparent that the invention fully achieves the intended aim and objects.
The invention as disclosed is susceptible to several variations and modifications all of which will come within the scope of the invention.
Moreover all of the details can be replaced by other technically equivalent elements.
