COMPACT ANTI-FLOOD BARRIER, FOR WINDOWS, A

IMPROVED SEAL

[0001] The present invention relates to a compact anti-flooding barrier, of the type with a removable bulkhead for window frames, with improved sealing.

Field of application

[0002] The innovation finds particular if not exclusive application in the sector of accessory devices, which can be installed if necessary, aimed at safeguarding the interior of buildings when extreme conditions occur from inclement weather events, such as flooding and tides .

[0003] In general, windows for buildings are known, having the main purpose of ensuring effective protection against bad weather, thermally and also acoustically insulating the interior of the building. In particular, the doors and windows existing today are effective in protecting environments from temperature variations and the action of the wind, and yet they are not the same or they are certainly less so to prevent the migration, inside the building, of water. . This is certainly not the case with rainwater protection, both because the phenomenon is episodic and because the amount of water that generally hits the window or door is modest, all the more so in the case of the more frequent applications where the windows are placed. in areas or recesses mostly always protected. Instead, it is the hypothesis, fortunately less frequent, in which buildings are affected by natural disasters, such as floods, or other phenomena, such as, for example, high water in nearby Venice.

[0004] It is therefore evident that the current doors and windows, now commonly installed in buildings, are insufficient to prevent water from seeping through them, or even to freely cross the obstacle of the door or window, considering the thickness of the remaining openings perimeter, this mainly due to the uneven coupling surfaces. Not even the use of the most advanced seals can overcome the problem, since it is evident that the pressure that insists on it is proportional to the level that the water reaches. It follows that, since these are rather important phenomena, such as violent flooding of rivers, the level reached by the water is always sufficiently high, to the point of making any traditional measures useless.

State of the art

[0005] The solutions adopted to prevent water from entering a building are numerous today; in order to determine the state of the art closest to the invention, a conventional check was carried out, interrogating public archives, which led to the identification of some prior art, including: D1: US3861081 (Maskell);

D2: BE0882294 (S.t.r.v.);

D3: FR2723137 (Berard);

D4: US7523589B1 (Smith);

D5: GB2453919 (Kirk);

D6: GB2458519 (England);

D7: GB2381030 (McGrath;

D8: DE4023286 (Buss);

D9: US7523589 (Smith);

D10: ITTV20110072 (Casari et al.).

[0006] In summary, D1 suggests the use of a frame to be secured on the sides of the lower part of a door, with straight C-type segments conveniently provided with sealing means, having the function of guiding the introduction from and hold in position a panel of waterproof material, which if necessary is inserted along said support structure and then, once the emergency has ceased, be removed.

[0007] In D2 a highly insulating window is proposed, suitable for both doors, windows or other. From the practical side, it consists in providing, perimetrically to the counterframe anchored along the opening to be closed, a seat, within which a tubular gasket with an inflatable chamber is allocated. Said seat and therefore the gasket coincide with the edge of the frame of the moving parts of the window, so that in the closed condition, if necessary, a fluid can be introduced inside the chamber, the pressure of which will gradually tend to dilate the gasket itself as long as it does not insist vigorously along the edge of the closed moving parts.

[0008] D3 instead describes the interposition, between the tubular element and the edge of the counterframe of the window against which the movable part closes, of a shaped rubber profile. In this case, said profile, being shaped on one side to accommodate the expandable portion of the tubular element and on the other plane, requires the latter part to insist on the perimeter surface of the subframe.

[0009] D4 proposes an adjustable barrier resistant to water flows, for removable application in a window or door opening or the like. Said barrier is housed inside an elastic bag and can be laterally expanded in such a way as to engage the sides and bottom of the opening to be protected. An adjustment mechanism comprises a shaft which protrudes upwards from the upper part of the frame, approximately in the center of the same, and mounts a handle which has a double function, respectively on one side acts as a support means for carrying the panel, on the other hand, by rotating said shaft it allows to act on the adjustment mechanism to vary the dimensions of the panel in width. Improved peripheral sealing minimizes the likelihood of corner leakage. For large openings, lightweight posts are provided to support center zones adapted to the center of the panel and to increase downward sealing. Light uprights can also be positioned between an opposing pair of barrier panels to close and isolate even large openings.

D5 discloses a flood barrier for a door comprising an adjustable panel with a rubber woven along the edge. The flood barrier features a series of threaded pins which are used to force the rubber edging into contact with the door frame creating a hermetic seal phase around the edge of the barrier. The panel can be made of lightweight material, such as aluminum.

[0011] D6 suggests an apparatus for protecting a building against flooding by water, which comprises a barrier, with a first surface preferably convex, facing towards the water, and the other second surface preferably concave, positioned towards the interior of the room, said first surface being delimited by a pair of generally parallel lateral edges and support means for the barrier in an opening through which water can enter the building. Preferably the barrier support means are attached to the second surface and comprise rods, placed in bars with the stop elements, which are movable in one direction so as to engage the door frame and in the opposite direction to release the barrier from the frame. . Preferably, the rods are mounted on a first toothed wheel which can be rotated by means of a second toothed wheel with an integral handle, the rotation of which causes the rods to move towards and away from the movable frame. Preferably, a wing nut and bolt are provided to urge the barrier to move with respect to the door frame towards and facing the side of the flooding, making a seal when the barrier is fixed to the door frame.

[0012] D7 is a flood barrier that can be adjusted horizontally and vertically, for adaptation to a door. The flood barrier includes an adjustable steel frame and a waterproof fabric cover sealed to the frame. Each barrier can be used on top of each other to create a greater barrier.

[0013] In summary, D8 describes a frame solution for sealing door or window openings comprising side profiles provided with external perimeter sealing edges. This solution includes a multi-angle frame that can be inserted at the opening of the building, which frame is provided with a cover plate intended to be placed under tension at its surface. The side profiles are provided with compressible gaskets, placed in correspondence with the peripheral surface. The lengths of said side profiles are variable since the profiles themselves are foreseen to be extendable by means of tensioners in order to allow the compression of the gasket profile against the walls of the opening to be occluded. Said gasket is expected to be shaped with an L-shaped profile, sealing a suitable cover plate and in which the side profiles are shaped in a U-shape.

[0014] In D9, a removable anti-flood barrier solution is proposed for installation within the opening of a window or door of a building comprising an adjustable frame in lateral extension and provided with a curtain panel which it is provided extensible so as to engage the sides and the base of the opening. The extension adjustment mechanism comprises a threaded bar placed vertically and protrudes upwards in correspondence with the upper part of the frame, approximately in correspondence with the center, which mounts a handle to allow portability, where the rotation of said bar allows to adjust the width of the panel with a ratchet or parallelogram mechanism, this in order to improve the perimeter seal and also to minimize the loss of seal at the corners. The solution provides for the possibility of integrating further uprights in order to better provide support to the central areas of the structure if the same is intended to be positioned in large openings.

[0015] Finally, in D10, a transportable anti-flow barrier is proposed, with an adjustable frame, to support a pre-existing window frame, of the type designed to prevent the penetration of water from flooding, from exceptional events through windows and doors, which consists in: a closed infill panel joined to the frame, an expandable U-shaped frame respectively consisting of two lateral uprights joined at one end by means of angle brackets to a base crosspiece and an intermediate connecting crosspiece between said two uprights lateral, a third intermediate upright with respect to said first two, which third upright is perpendicular and joined with respect to the intermediate crosspiece and to the base crosspiece. Said uprights and said crosspiece and crosspiece develop a telescopic function being adjustable in a permanent condition; where the means for adjusting said uprights and said crosspiece and crosspiece are such as to achieve adjustment of the frame according to the dimensions of width and height.

[0016] Ultimately, it can reasonably be considered known:

- an anti-flood barrier consisting of at least one rigid panel and a relative sliding frame, or vertical guide, to be placed in front of the pre-existing window frame, which can be positioned at the door of a door, threshold of a window or other openings, through the which can migrate a flow of water due to an extraordinary meteorological and meteorological event;

- an anti-flood barrier, made as described above, also of the transportable, removable, and installable type if necessary;

- and where the said barrier is of the type consisting of a flat or convex / concave surface, with, along the perimeter, a gasket-like border made of elastomer for greater sealing;

- and again, in which said barrier is of the type configured to vary the dimensions in width, through the action of screw adjustment means;

- an anti-flood barrier comprising an expandable and adjustable frame which is combined with infill panels and a perimeter sealing gasket, where said frame is of the type including a central crosspiece, base crosspiece, with lateral and lower corner uprights which are movable telescopically and / or slidingly, comprising screw adjustment means which allow its expansion and adjustment in a permanently sealed condition and also allow its contraction in order to remove said barrier from the window frame;

- screw adjustment means that act centrally or originate from the central area of the barrier to act peripherally in a cross or radial pattern or with a parallelogram mechanism, which are applied in correspondence with the horizontal median axis by acting with direct thrust on two lateral uprights opposite, and in correspondence with a central upright by acting vertically with direct thrust on the base sleeper, or also in correspondence with the lower corners by acting diagonally with direct thrust on movable angles.

Drawbacks of the state of the art

[0017] In general, conventional sliding or pull-out panel solutions appear rather empirical and inefficient, both due to the limit set by the height of the panel, and relative to functionality and aesthetics; furthermore, it is known to the operators of the sector that the doors and windows that integrate solutions to guarantee waterproofing are particularly onerous, heavy, bulky and require preventive architectural works that are not always feasible, especially in areas restricted by the fine arts and in any case of demolitive and uncomfortable, in the face of which the replacement of conventional doors and windows is equally often not justified. Add to this the occasional nature of exceptional events which, given the uncertainty of the phenomenon, contributes to not justifying the adoption of these precautionary measures.

[0018] In other words, the removable barrier solution to be set up on the door only upon the occurrence of the exceptional event currently appears to be the only most practicable solution in order to reduce the effects of exceptional flooding, and the advantages are inherent in the fact that it has no aesthetic impact, being used only when necessary, therefore in the transportability and speed of putting into work. Conversely, the limits of currently known anti-flooding barriers, particularly in critical areas, consist in the fact that only in some cases it is possible to minimize the entry of water into the building, i.e. when the pressure exerted by the water level is contained and when the barrier - door coupling surfaces are substantially regular. The known and available devices are generally not sufficient to guarantee a good peripheral seal; in principle, in fact, it can reasonably be agreed on the fact that the peripheral seal is ensured by the gasket which, being directly stressed in several points due to the irregularities of the surfaces and also due to the uneven thrusts exerted by the adjustment or tensioning means, it is by no means sufficient to guarantee the required watertightness.

[0019] It has therefore been found that all the solutions found in documents D1-10, in the applicant's opinion, have drawbacks and limitations consisting both in the fact that their structuring does not seem to guarantee an optimal hermetic seal against the flooding, especially in correspondence of the lower corners, and further it has been found that the structure of the frame and the adjustment in extension that is allowed to the same can be optimized.

[0020] Also the aforementioned solutions aimed at increasing the angular seal, of which for example in D8 or D10, can be improved if a high seal or hermetic type is required. In fact, it has been found in professional practice that the perimeter leakage of the water flow on the inner corners of the barrier is a frequent phenomenon and that it is also very harmful in the case of flooding of valuable environments, such as the floors of historic buildings, or in the case of of delicate materials stored on the ground floor or in the basement, as generally occurs in store warehouses containing easily perishable foodstuffs.

[0021] In particular, it has been found that even the said solutions designed to improve the perimeter and / or angular seal, if subjected to high thrusts for a prolonged time, tend to deform, presenting bending and / or misalignments on the lower corners due to the high length of the orthogonal and / or diagonal adjustment means, otherwise called pushers or tensioners, which originate centrally in the manner of a radial pattern; in order to limit said deformations and increase the resistance of the system, the diagonal pushers therefore have considerable sections, with a consequent increase in cost and weight, or by limiting their use.

[0022] It was also noted that, in the particular and known case of historic buildings in Venice frequently subjected to high tide, on the ground floor, all the emergency and harmful situations described above sometimes occur jointly; furthermore, there is the fact that in these buildings the shoulders, thresholds and sills of the doors and windows are generally made of stone, with often irregular or worn surfaces, making it sometimes difficult to ensure an effective seal against said leaks when the frame it is geometrically regular and an adequate gasket is not provided, that is, such as to compensate for the lateral thrust by adapting to said irregularities. In these cases, therefore, the need is even more felt to have an innovative removable type solution, more effective in perimeter and angular sealing, which is also compact and light, easily transportable and stackable.

[0023] For this and other reasons, ultimately, there is a need to identify alternative proposals and, at the same time, capable of making technological progress with respect to the solutions currently in place.

Brief description of the invention

[0024] These and other purposes are achieved with the present innovation according to the characteristics of the annexed claims by solving the problems set forth by means of a removable anti-flooding barrier (10), supporting a pre-existing window frame, suitable for preventing the penetration of the flow of water. 'water; said barrier, being compact, light, easy to use and resistant in such a way as to ensure less deformation and an improved seal, particularly on the lower corners. Said barrier (10) provides an expandable frame (100) and adjustable with infill panels (114-5), covered with a rubber seal (101) of the semi-integral type in the form of a waterproof and extensible sheath, the which is made up of a central crosspiece (102), a base crosspiece (106), lateral uprights (103-4) and lower corner pieces (112), with special screw adjustment means (108-110) integrated inside of the frame which implement orthogonal thrusts of the direct type (S1, S2) combined with diagonal thrusts of the derivative type (S3) or additional, by way of a fine adjustment at the lower corners.

Aims and advantages

[0025] In this way, through the considerable creative contribution whose effect constitutes an immediate and not negligible technical progress, various and remarkable objectives are achieved.

[0026] A first advantage consists in the fact that the proposed anti-flooding barrier is extremely compact, integrated, light and easy to handle, in order to facilitate transport, storage in piles and installation on the window frame, allowing a quick and effective installation even in the case of emergencies as often happens in the case of floods or overflows; the proposed solution is also useful in the case of frequent installations, as for example happens in the premises on the ground floor of the historic city of Venice.

[0027] A second advantage consists in the fact that the proposed barrier is very resistant and effective in the permanent seal, being expandable and adjustable in such a way as to ensure less deformation and leakage in the lower part, or below in the central crosspiece, compared to the known and conventional solutions. The invention ensures an improved seal also in correspondence with the lower corners, where the difficulty of obtaining a permanent hermetic seal by applying thrusts of the direct and derivative type combined with each other is known; in particular, additional diagonal thrusts are envisaged as an additional fine adjustment, which is consequential or derived from one of the main thrusts, horizontal and / or vertical.

[0028] A third advantage, linked to the previous ones, consists in the fact that the foreseen structure of expandable frame allows to apply, in the basic configuration, a minimum number of adjustment means, i.e. one for the horizontal thrust, one for the vertical thrust, and two for said diagonal thrusts or one for each of the lower edges; and furthermore it is foreseen that said adjustment means are applied locally, and not centrally or radially, having extremely small dimensions to reduce the free distance between the anchoring point on the fixed part and the final point pushed on the mobile part, so such as to significantly reduce the deflections under stress of each adjustment means and also the consequent deformation on the frame, with the advantage of maintaining thrust and sealing. Such a solution also has the not negligible advantage of reducing the overall weight of the barrier.

[0029] A fourth advantage consists in the fact that the said anti-flooding barrier is cheap and can be easily manufactured on a large industrial scale.

[0030] These and other advantages have the advantage that is by no means negligible, of achieving an anti-flooding barrier with a good technological, functional and extremely reliable content.

[0031] Other advantages will appear from the following detailed description of some preferential construction solutions with the help of the attached schematic drawings whose execution details are not to be construed as limiting but only and exclusively exemplary.

Practical execution of the invention

[0032] The object of the present invention refers to an advantageous anti-flooding barrier (10), supporting a pre-existing window frame, which has improved sealing and is of the easily transportable, operable and storable type, being compact and thin in shape, like a suitcase with handles. Basically, the said barrier acts as a mobile or removable bulkhead, designed to prevent the penetration of water from flooding by exceptional events through windows and doors, where said improved sealing occurs particularly in correspondence with the lower corners, i.e. where, generally, more leaks occur.

[0033] The said anti-flooding barrier (10) provides an expandable (100) and adjustable frame, with infill and anti-shattering panels (114-5), covered with a rubber seal (101) of the semi-integral type in such a way of waterproof and extensible sheath. The said expandable frame (100) is integrated inside the said barrier (10, 101), between a front panel (114) and a rear panel (115 fixed one on each side (128-9) or symmetrically with respect to it (100 ), and consists of a central crosspiece (102), a base crosspiece (106), with lateral (103-4) and lower corner posts (112) which are telescopically movable (103) and / or sliding (112 ) as a slider, with adjustment means (108-110) which allow its expansion and adjustment in a permanent and improved sealing condition, also allowing its contraction in order to remove said barrier (10) from the window frame.

[0034] Preferably, said screw adjustment means (108-110) are of the threaded rod type, or worm screw, which rotates on its own axis by axially pushing a movable point from a fixed point of the frame, expanding; for this purpose, said bar or screw is then anchored to the fixed part of the frame by means of a base (111) and is constrained to the mobile part by means of a connection means, otherwise called connector (113), which allows said translation being constrained to it and generally threaded according to said bar or screw. The provided adjustment means implement horizontal thrusts (S1) on said lateral uprights (103-4), acting on one side only (104, S1), vertical thrusts (S2) on said base sleeper (106), and also diagonal thrusts (S3) on said lower corner pieces (112). More in detail, said screw adjustment means (108-110) are integrated inside the frame (100, 114-5) and carry out orthogonal thrusts of direct or main type, or a horizontal one (109, 104, S1) and a vertical one (108, 106, S2), which are combined with diagonal thrusts of the derivative type (110, S3) or supplementary being based on at least one of them (S1) to be added as a fine adjustment at the lower corners. All said means (108-110) are positioned below the crosspiece (102) and in proximity to the respective movable part in such a way as to act near the point of application of the thrust (S1, S2, S3) and limit the deformations in the lower part of the anti-flood barrier (10, 100) and increasing the seal on the lower corners.

[0035] In the present description, for the purposes of the invention, said adjustment means (108-110, S1-3) are preferably of the screw type, as described above; however, alternatively, equivalent mechanical members of the cam type, or of the pneumatic, hydraulic or even electromechanical type, are suitable for the invention, in order to facilitate their operation.

[0036] More in detail of the preferential embodiment of said frame (100) and said adjustment means (108-110) (Figs. 1-4), it is envisaged:

- a first screw adjustment means (108) which actuates a horizontal thrust (S1) of the direct type, on a lateral upright (104) which slides at one end of the central crosspiece (102) of the frame (100) on the plane vertical longitudinal center line (138), being it (104) shaped as a T-square with a trapezoidal head, to uniformly distribute the load at full height, and symmetrically with respect to the other upright which is instead fixed (102- 3); said first means (108, S1), with the anchoring base (111) near the said upright (104) and the connector (113) on it (104), being aligned with a horizontal axis at a distance between 1 cm and 10 cm below the said central crosspiece (102);

- at least a second screw adjustment means (109) which actuates a vertical thrust (S2) of the direct type on said base sleeper (106), with axis on the vertical transversal center line (139), by means of a Y-shaped fork (105) which is constrained to said central crosspiece (102) and to a base bracket (107) constrained to said base crosspiece (106), which are close together to respectively join said base anchor (111) and said connector (113), in such a way as to move the load away from the center of the frame (10, 100) reducing the deflection of the said cross member (102) and bringing the point of application of the thrust (109, S2) closer ) to said sleeper (106);

- third screw adjustment means (110) which actuate a diagonal thrust (S3) of a derivative type on at least each lower corner (112), which slides in the manner of a horizontal cursor at the end of said base sleeper (106) ; said third adjustment means (110, S3), being therefore provided in pairs or in number two means (110, S3) equal to each other and arranged one symmetrically to the other, with respect to the vertical plane of the transverse center line (139); and where the anchoring base (111) of each of said third adjustment means (110, S3) is fixed on the lower part of each lateral upright (103-4) to act with an inclined axis on the lower angle (112). neighbor, being constrained to it (112-113) in such a way as to push further horizontally the lower part of said uprights (103-4) and jointly push vertically the ends of said base sleeper (106), in addition and consequent to said lateral direct expansions (103-4, 106, 108-9, S1-2); and where the said inclined axis (110, S3) is of a degree between 30 sexagesimal degrees and 60 sexagesimal degrees, and passing through the lower corner of the said expandable frame (100, 112).

[0037] In the preferred embodiment configuration, for the purposes of the invention, each of said screw adjustment means (108-110) has the free portion of a threaded rod, i.e. subjected to stress and deformable, which is less than 20 cm in length, considering the distance between the anchoring point on the fixed part, that is the said base (111), and the point pushed on the mobile part, that is the said connector (113) (Fig. 1).

[0038] The said expandable frame (100) and the said panels (114-5) are covered with a rubber gasket (101) of the semi-integral and monobloc type, shaped like a waterproof and extensible sheath, which entirely covers at least the front face (114, 128) facing the flow and also, without interruption, the side faces constituted by said uprights (103-4) and the bottom (130), from which (103-4, 130) protrudes in an orthogonal direction at least a continuous perimeter sealing lip (122) on the window frame or acting on the shoulders and threshold (Figs. 1-5). Preferably, said lip (122) is double in the shape of a C, with two continuous and parallel protrusions, so as to increase the seal and also such as to allow, if necessary, a compensation insert (124) of the edge to be interposed with restraint. form of deformable thickness, for example in elastomer or rubber, which compensates for any irregularities in the interface surface as sometimes occurs in the case of parapets or thresholds of ancient buildings. In particular, such an insert solution (124) possibly added by the user as an accessory is particularly useful if there are profiles or skirting boards at the base of the door jambs to be protected.

[0039] The said rubber gasket (101) on the rear face (129) has openings (123, 135) for accessing the said screw adjustment means (108-110), where these openings correspond to the respective openings (117) which they are present on the panel below (115); moreover, on the upper face of the gasket there is an opening (136) for inserting from above, after expansion being made of rubber, said expandable frame (100, 102-3, 106, 108-110, 114-5, 130) . They (100, 101) are then mounted one inside the other and closed at the top, from the outside, with a lid (118) having a C-shaped cross section, from which at least one handle (119) protrudes upwards. supportive; preferably, two centrally aligned handles (138) are provided. Finally, said frame (100, 114-5), gasket (101) and cover (118) are joined together by means of mechanical fixing pass-through means (131) on bushing (132), through holes (133), so such as to have said handles (119) facing upwards and also such as to ensure watertight integrity between the parts in contact (100-1, 114-5, 118, 133), being said gasket (101) in soft rubber and including a sealing lip (134) protruding upwards (Figs. 4, 6a, 6b).

[0040] Still in the preferential embodiment of the invention (Figs. 1, 4-5, 8, 11), it is envisaged that said rubber gasket (101) is wrapped in tension and joined to said frame with panels (100, 114 -5), by means of integrated rubber buttons (121) protruding from both sides, horizontally aligned and equidistant to each other, in such a way as to couple with the corresponding slots (116) present in said panels (114-5). Furthermore, to facilitate the coupling at the upper edges, a rubber flap (137) is provided which is integrated into the gasket (101) and protrudes inwards as an undercut so as to cover and retain the end upper of said front (114) and rear (115) panels.

[0041] Furthermore, an external protection cap (126), for example made of bent sheet metal (Figs. 2-4), is to be superimposed on said anti-flooding barrier (10), able to completely adhere to the external surface and also to cover the upper part where it has an inclination towards the front face (128) like a flap, and also is in continuity on the back face (129) where the edge is partially folded like a snap flap to facilitate its installation, lifting or removal. In particular, said external hood (126) is optionally added by the user, being supplied as an accessory, snapping on after mounting the bulkhead in such a way as to preserve the rubber of the gasket (101) in the front sealing side (128 ) from blunt instruments and / or accidental blows.

[0042] For the purposes of the invention, the sealing pressure exerted on said gasket (101, 122) by said adjustment means (108-110, S1-3) takes place by activating the expansions sequentially, or by first tightening at least one means for direct thrust and then the means for derivative thrust. Preferably, said actuation takes place in the following order: first said first horizontal adjustment means (108, S1), then said third adjustment means (110) in such a way as to actuate said diagonal derivative thrusts (S3), and finally said second vertical adjustment means (109, S2).

[0043] Finally, compatibly with the excursion guaranteed by the adjustment means (108-110) and by the expandable parts (104, 106, 112) of the frame (100), the anti-flooding barrier (10) is expected to be of the standardized type or universally adaptable, being produced in a limited number of widths or sizes; by way of example, it (10) can be made with fixed widths at intervals of 50 mm or 100 mm, depending on the expansion achievable by said adjustment means (108-110) and by the movable parts of the frame (104, 106 , 112). Furthermore, to facilitate the immediate recognition of said standardized size, during an emergency, it is useful to provide an alphanumeric indicator (127) for dimensional recognition which, for example, is obtained in relief from the mold, directly on said rubber gasket (101), and corresponds to the maximum or minimum width of said barrier or of the window opening, as can be seen from the reference figures relating to the preferential but not exclusive construction configuration where 1200 in millimeters is indicated, (Fig. 2) or alternatively 1150 in millimeters, (Figs. 5-6, 9).

[0044] The proposed barrier (10), depending on the specific application, or the pre-existing window frame to be protected and / or sealed, can therefore be arranged according to the desired dimensions; by way of example, in the case of the most widespread doors and windows where this solution is applicable such as, for example, the doors on the ground floor at the tax level, the following dimensions are suitable for the invention: a thickness between 40 mm and 80 mm , preferably approximately 65 mm approximately, a height between 400 mm and 800 mm, preferably approximately 500 mm, and a standardized width or size alternatively equal to 700, 750, 800, 850, 900, 950, 1000, 1050, 1100, 1150, 1200, 1250 or 1300 mm, or other multiples of 50 mm or 100 mm.

[0045] In a variant embodiment of the invention, not shown in the figures, dimensions corresponding to the entire window frame are provided, i.e. such as to completely block the opening, as a full-height integral barrier; such a solution, by way of example, is effective and advantageous in the case of tornadoes or severe floods. For doors and / or openings of large dimensions, it is therefore advantageous to provide said expandable frame with further adjustment means which implement diagonal thrusts of a derivative type also on the upper corners, symmetrically with respect to said lower corners.

[0046] The advantageous anti-flood barrier solution (10) made as described above, is economical and easily manufactured on a large industrial scale, has a compact and integrated configuration, is easy to use, being light, handy and quickly adjustable, and is very resistant ensuring less deformation and leakage if subjected to high loads from flooding or overflow, compared to known and conventional solutions; in particular, the proposed barrier (10) ensures an improved seal at the lower corners, where the difficulty of providing a hermetic seal is known.
