Definitions
- the present invention relates to an armour-clad, bullet-proof closure means like a door, window, shop-window and the like ("closure means"), integrally made of aluminum alloy and constituted by the assembly of extruded structural shapes for forming two frames coupled with each other, one frame of which, the interior frame, is made of traditional aluminum alloy, and the other frame of which, destined to remain outside the room, is made of an aluminum alloy endowed with very high characteristics of mechanical strength and toughness, which makes it possible to produce an armour-clad closure means particularly resistant to the penetration of bullets.
- closure means integrally made of aluminum alloy and constituted by the assembly of extruded structural shapes for forming two frames coupled with each other, one frame of which, the interior frame, is made of traditional aluminum alloy, and the other frame of which, destined to remain outside the room, is made of an aluminum alloy endowed with very high characteristics of mechanical strength and toughness, which makes it possible to produce an armour-clad closure means particularly resistant to the penetration of bullets.
- the so said armour-clad doors and armour-clad windows are made, in certain cases, by applying a steel plate to the outer face, or to the inner face, of a traditional door; in other cases, the door is totally made of steel sheet, having the shape of a box-like body inside which a honey-comb structure is provided, which performs the functions of spacer and of connecting body; the so obtained door is then mounted on a door jamb constituted by a metal frame rigidly anchored to the opening provided in the wall.
- EP-A- 191190 relates to an armoured, bullet-proof closure mean accomplished by means of extruded shapes, comprising an internal part made of traditional structural shapes and a part destined to remain outside made of flat, bullet-proof plates obtained by extrusion of a special aluminium alloy (claim 1, lines 40 to 52),with Si 0,6 to 0,8 and magnesium (claim 4, lines 8 to 11), said external part being connected to the internal part through yielding elements.
- DE-A- 2824199 (G.KUGEL) relates to a bullet-proof closure mean accomplished by extruded hollow shapes into wich a bullet-proof plate is inserted in an inclined position in order to deviate a bullet wich strikes it (page 8, lines 6 to 9). Instead of the inclined plate, sand or concrete can be placed into the hollow shape in order to render it bullet-proof (fig.3).
- DE-U- 8612216 (H.SALZER) relates to a bullet-proof closure mean accomplished by a system of hollow shapes into wich flat plates of high mechanical strength are inserted.
- DE-A- 2324724 (BLOHM + VOSS AG) relates to an armoured member consisting of two flat plates between which elastic elements are inserted, in order to absorb the impacts.
- ALLUMINIO L11 (R.PILI) relates to a bullet-proof closure mean integrally made from aluminium alloy and comprising an inner part of extruded profiles of traditional type and an outer frame made of aluminium alloy plate endowed with high mechanical strenght, said outer frame being internally provided with protrusions and seats for retaining coupling blocks.
- a purpose of the present invention is to provide a closure means, such as a door, a window, a fixed or openable shop-window, or the like, of bullet-proof armour-clad type, integrally made by means of the assemblage of extruded structural shapes of aluminum alloy, and more precisely of structural shapes of aluminum alloy of the traditional type for closure means, combined with structural shapes of a special aluminum alloy endowed with a high level of mechanical strength and toughness, which makes said aluminum alloy suitable for solving the specific problems of the armour-cladding in the building field with the typical flexibility, and by the manufacturing techniques of the normal closure means made of aluminum alloy.
- Another purpose of the invention is to provide an armour-clad, bullet-proof closure means which can be obtained by means of the assemblage of extruded structural shapes of aluminum alloy, partly modular and polyfunctional, so anchored to each other as to give rise to two mating frames easily and rapidly obtainable, and such to show high characteristics of resistance to the atmospheric agents.
- a further purpose of the invention is to provide an integrally armour-clad closure means in which the armour-clad portion is an integral part of the support frame of the closure means, securing a high protection agains the penetration of bullets and the attack by cutting tools, and hence capable of constituting a valid protection structure for fixed and openable glass windows and glass doors, doors, windows, and the like, in rooms in general, and in particular in rooms of houses, banks, shops, post offices and the like.
- closure means like a door, window, shop-window and the like
- closure means integrally made of aluminum alloys, and constituted by a plurality of extruded base-structural shapes, of hollow shape, so positioned relatively to each other as to form two mutually opposite frames, joint-coupled with each other by means of blocks or continuous bars which can be inserted inside seats provided on the mating faces of the same frames, and so dimensioned as to form both the frame constituting the jamb and the glass-holding frame of a door or window of the leaf type or fixed
- the structural shapes forming the frame destined to remain inside the room being made of an aluminum alloy of the traditional type for fixed or movable closure means of aluminum
- the structural shapes forming the frame destined to remain outside the room are made of an aluminum alloy endowed with very high mechanical strength and high toughness, the alloy known under the "Series 7000"
- the closure means of the invention is to be understood as being both a fixed closure element, i.e., constitued by a glass-frame mounted fixed inside the opening provided in a wall, e.g., for a fixed shop-window, and a shutter (or glass-door or window) of leaf type, contained inside a frame normally denominated "jamb".
- Figure 1 shows a partial transversal sectional view of a glass shutter, hinged onto a jamb upright, i.e., a closure means constitued, according to the invention, by extruded structural shapes of aluminum alloys having different mechanical characteristics, but all of them being equally suitable for being processed according to the known extrusion techniques for the aluminum alloys for closure means and the like.
- the closure means of Figure 1 is constituted, according to the present invention, by the assembly of a reduced number of base structural shapes, of a traditional aluminum alloy, forming, after the assemblage, the frame of a jamb, and a frame for a glass-door or window, both destined to remain inside the room; with these frames a frame destined to remain outside the room is coupled, which is accomplished by assembling structural shapes of a "Series 7000" aluminum alloy, already known for other uses, such frames constituting the armour-clad portion of the jamb-rotatable shutter assembly.
- the box-shaped structural shapes 1 constitute, after the assembling, as it will be explained in greater detail in the following, the jamb of a door or shop-window, to be anchored onto the walls of the building room; they are provided, on one of their sides, with the external continuous toothed appendices 1a-1b, and with two equal parallel appendices 1c-1d in a central position, whilst on the opposite sides thereof continuous protrusions 1e-1f-1g are provided, which are opposite to each other, and are "T"-shaped, suitable for enabling various types of couplings with elements for fastening glasses, gaskets and butt-straps, as it will be better explained hereunder.
- the extruded structural shapes 1 constitute a frame (jamb) which is made of an aluminum alloy of the type already used for aluminum closure means (Series 6000), and which is destined to remain inside the room.
- a structural shape 2 can be snap-coupled, which is made of a "Series 7000" aluminum alloy, known under the Registered International trade mark "ALUBLIND" of ALLUMINIO ITALIA SpA, and being the subject matter of the Italian Patent No 1163151 (Application No 20156 A/83), whose characteristics of mechanical strength and toughness make it suitable to resist to the penetration of bullets and of perforating tools.
- ALUBLIND Registered International trade mark
- composition of "ALUBLIND" aluminium alloy in % by weight, is the following : Si upto 0,08%; Fe upto 0,12%; Cu 0,6 to 0,9%; Mn 0,05 to 0,20%; Mg 1,5 to 1,9%, Zn 4,6 to 5,2%; Zr 0,08 to 0,14%; Ti upto 0,03%; Al balance to 100%.
- Each structural shape 2 is of the double-shield structure, i.e., it is composed by two separated elements 2a-2b, between which the-air gap 3 contributes to dampen the residual energy of the bullets and, after the assemblage, said structural shapes constitute an armour-clad frame which is destined to remain outside the room to be protected.
- the stable union of the two frames is obtained by means of the insertion of two rows of moulded blocks or continuous bars 4-4a, of a stiff and thermally insulating material, snap-mounted at pre-established distances inside the seats defined by the appendices 1b-1d and 1c-1a of the structural shape 1 and anchored onto the structural shape of the external frame 2 by means of known pins or rivets, not shown.
- the external structural shapes 2 are furthermore provided with sloped stop surfaces 5, with a gasket 6, for the protruding edge of the shutter of the closure means.
- the glass-door or window is also constituted by an internal frame formed by the assembly of structural shapes 7 of a traditional aluminum alloy, of box-shaped type and provided with contiuous appendiced 7a-etc., equal to those of the structural shapes 1; the base of the structural shapes 7, i.e., the internal, on-sight flat face 7b, is horizontally extended so to show a wing 7c, such to constitute, at its end, a seat 7d provided with a stop gasket 7e cooperating with a gasket 7f snap-anchored onto the structural shape 1.
- the outer face of the wing 7c is then hinged, in a known way, onto the external flat face of the structural shape 1 of the jamb.
- a double-shield structural shape 9 is snap-coupled, by means of two rows of moulded blocks or continuous bars 8-8a; said double-shield structural shape 9 is of a "Series 7000" aluminum alloy, and its upper wing 9a is longer than the lower wing 9b, so to constitute a continuous means for holding, with the interplacing of a gasket 10, a bullet-proof glass sheet 11, or the like.
- the sheet 11 is kept blocked against the wing 9a by means of a pin 12 inserted through a glass-locking element 13, of a traditional aluminum alloy (Series 6000), which in its turn is snap-inserted between the protrusions 7g protruding from the structural shapes 7.
- An "L"-shaped butt-strap 14 suitable to be snap-applied to the glass-locking element 13 contributes to make the glass-locking element coplanar with the on-sight plane of the structural shapes 7 and 1.
- a gasket 15 is inserted between the two wings 2a-2b of the external structural shapes 2 for the purpose of securing a tight sealing against the atmospheric agents, whilst the individual structural shapes 9 show a recessed step 16 acting as a stop for the end of the wing 2b of the structural shape 2, and a sloped appendix 17 acting as a stop for the end 5 of the wing 2a of the structural shapes 2.
- the closure means results hence constituted by two coupled frames forming the jamb, and by two coupled frames constituting the glass-door or window, the one of which, which is destined to remain inside the room, is made of extruded structural shapes of a traditional aluminum alloy, and the one of which, which is destined to remain outside the room is made of extruded structural shapes of an aluminum alloy of "Series 7000" type.
- the invention provides a limited set of other structural shapes, as described above in connection with the figure listing; furthermore, the base-structural shapes 1 and 7 can be used both for forming jambs and leaf shutters.
- the structural shape 7 of a traditional alloy can constitute the internal jamb or the internal shutter of a leaf, or also the central internal upright of a frame with crosspieces placed in a "T"-arrangement relatively to the upright; in a similar way, also the same structural shape 7 can constitute the upper crosspiece of a frame with uprights and crosspieces arranged according to a "T" configuration, as well as the internal windowsill-crosspiece of the jamb.
- the internal structural shapes 1 can constitute, as already said, the inner shutter of a leaf, as well as the inner stop jamb.
- the subject set of the present invention comprises structural shapes 18 (Figure 10) of "Series 7000" alloy, constituting the external central uprights of a "T"-frame, wherein between the wing 18a and the end of the lower, shorter wing 18b a bullet-proof glass can be anchored, and on the opposite side an openable shutter made from the structural shapes 9-7b ( Figure 1) can be kept to a stop.
- the structural shape 19 of "Series 7000" alloy of Figure 11 can constitute the external flat face of a door or of a window-glass, or the wainscot thereof, or also an oversize upright for outside, to be coupled with the oversize upright for inside 20, shown in Figure 5.
- the set of base-structural shapes provides a structural shape 21 ( Figure 4) of a traditional alloy, suitable for constituting a wainscot for the inner frame of a glass-door or of a window.
- the integral, armour-clad, bullet-proof closure means accomplished by means of the set of extruded structural shapes of aluminum alloys having different characteristics, besides exploiting the most advanced "Series 7000" aluminum alloys, and hence making it possible to obtain armour-clad closure means of reduced weight, obtainable by the usual extrusion-techniques, and also easy and quick to be assembled, offers the advantage of being particularly suitable for undergoing ornamental and protective surface treatments, such as paint-coating, anodizing, with obvious advantages of aesthetical character.
