[0001] The present invention relates to a reinforced door that has innovative and improved characteristics with respect to commercially available ones.
[0002] It is specified that a reinforced door (or intruder-resistant door) is a specific closure element intended to be installed in an opening for access to an enclosed space (be it a dwelling, an office or other) that has specific security characteristics against break-ins. Hereinafter, the expression "reinforced door" will actually reference all doors that have high standards of security against break-ins, such as for example armored doors, intruder-resistant doors, security doors and other equivalent devices.
[0003] Reinforced doors, from the point of view of providing buildings with high thermal and acoustic efficiency, are a fundamental element for insulating correctly the enclosed space that they control.
[0004] The most severe heat exchange problems are linked to infiltrations, since gaskets of the known type are generally insufficient to ensure a correct seal, especially if the installation space of the frame does not have predefined geometric and dimensional requirements.
[0005] The weight and volume of a reinforced door are generally such as to make it difficult (in some cases impossible) to provide correct (hermetic) mating of the gaskets of the leaf with the surface of the frame (or vice versa). In any case, these conditions can be lost rapidly due to the lack of elastic return of said gaskets (aging causes a greater tendency to plastic deformation, with consequent deformation of the gasket) and/or wear thereof.
[0006] Generally speaking, a closure element must ensure thermal and acoustic insulation with respect to the outside environment.
[0007] These performances cannot be ascribed exclusively to the sealing gaskets but also provide for the adoption of filling with rock wool (and the like) and cladding with internal panels made of insulating material.
[0008] However, the arrangement of these elements is not enough to avoid the presence of thermal bridges (a limited local region of the building enclosure that has a higher heat flow density than the adjacent constructive elements) and/or the transmission of sound waves.
[0009] The aim of the present invention is to solve the problems described above, by proposing a reinforced door that avoids drafts as a consequence of an optimum seal of the corresponding gaskets.
[0010] Within this aim, an object of the invention is to propose a reinforced door that is simple to install with a thermal and acoustic seal, even if the frame has been installed on the respective opening without strictly complying with the parameters prescribed by the manufacturer.
[0011] Another object of the invention is to propose a reinforced door that has a modest heat transmittance and therefore that thermally insulates in an optimum manner the installation space from the outside.
[0012] Another object of the invention is to propose a reinforced door that has good sound insulation and therefore isolates acoustically in an optimum manner the installation environment from the outside.
[0013] A further object of the present invention is to provide a reinforced door that has substantially low costs, is relatively simple to provide in practice and is safe in application.
[0014] This aim and these objects are achieved by a reinforced door, of the type comprising at least one frame provided with at least one upright and at least one crossmember that can be installed in an opening of a wall and at least one leaf provided with at least one perimetric border, with at least one panel that constitutes a face of said leaf, internal reinforcement and stiffening elements, insulating material and a lock controlled by respective bolts, between said frame and said leaf there being interposed at least one hinge for mutual connection, characterized in that it comprises, perimetrically with respect to said leaf, at least one sealing gasket intended to abut against a corresponding surface of said frame, said at least one sealing gasket having a closed rectangular shape with dimensions that are substantially similar to those of said leaf, the cross-section of said gasket comprising a base main body, which defines internally a closed chamber, and a curved band, which protrudes substantially from the outer centerline portion of said main body.

[0016] With particular reference to the figures, the reference numeral 1 generally designates a reinforced door.
[0017] The reinforced door 1 comprises at least one frame 2 provided with at least one upright (actually, the vertical uprights are two in number, are mutually parallel and face each other) and at least one crossmember (which is perpendicular to the two uprights and is arranged at the top) that can be installed in an opening of a wall.
[0018] The door 1 comprises furthermore a leaf 3 provided with at least one perimetric border 4, with at least one panel 5 that constitutes a face thereof, with internal reinforcement and stiffening elements 6, with insulating material 7 and with a lock 8 controlled by respective bolts 9.
[0019] At least one hinge 10 for mutual connection is interposed between the frame 2 and the leaf 3.
[0020] According to the invention, at least one sealing gasket 11 intended to abut against a corresponding surface of the frame 2, is provided perimetrically along the perimeter of the leaf 3.
[0021] The gasket 11 has a shape that is intended to eliminate (or at least reduce significantly) air infiltrations even if the predefined conditions of ideal alignment of the leaf 3 and of the frame 2 do not occur (due for example to imprecise mounting of the frame 2 or to geometric and dimensional problems of the opening that is present in the installation wall).
[0022] It is specified, therefore, that the at least one sealing gasket 11 has a closed rectangular shape with dimensions that are substantially similar to those of the leaf 3.
[0023] More specifically, it is necessary to point out that the gasket 11 is provided in one piece, so that it can be fitted on the leaf 3 by defining a sort of continuous ring that covers at least partially the perimetric border 4 of said leaf 3.
[0024] In order to provide this continuous ring, one begins with linear segments of an elastomeric profile that are as long as the sides of the leaf 3: by using specific joining apparatuses (blocks of elastomeric material that have opposite faces that are shaped appropriately to mate stably with the profile being used), one proceeds with a process for joining the linear segments until a closed gasket 11 is provided.
[0025] The joining process can occur by heat-sealing and/or thermocompression (if the profile and the joining apparatuses comprise at least one portion made of thermoplastic elastomers) or by means of specific adhesive bonding operations (which ensure a high tenacity and maintain it over time).
[0026] In order to achieve the desired sealing performance, the joining apparatuses have a shape that allows to mate segments that are oriented differently with respect to each other. The need may in fact occur to ensure that different parts of the leaf 3 abut against the frame 2 along different directions (for example due to the presence of edges and/or protruding tabs). Therefore, this leads to the need to orient the respective segment so that it can abut against the surface that is complementary thereto along the ideal direction.
[0027] It is furthermore necessary to specify additionally that the possibility is provided to adopt auxiliary joining means that are interposed between at least two consecutive segments intended to cover one side of the perimetric border 4 in order to allow any expansions of the gasket 11. The gasket 11 is in fact provided with dimensions that are suitable to mate by elastic forcing (therefore elongation of said gasket 11) with the border 4. In some cases, therefore, it is appropriate to ensure that the elastic deformations that are a consequence of the arrangement of the gasket 11 on the leaf 3 are located exclusively in some regions, in particular the ones that are less subject to air infiltrations.
[0028] This goal is achieved by adopting auxiliary joining means, which deform more easily than the elastomeric profile segments: during the arrangement of the gasket 11 on the leaf 3, the elastic elongations of the gasket 11 are located at the auxiliary joining means (with high deformability), ensuring that the segments of elastomeric profile maintain their ideal shape.
[0029] In particular, the cross-section of the gasket 11 comprises a base main body 12, which defines internally a closed chamber 13, and a curved band 14. The band 14 protrudes from the outer centerline portion of the main body 12.
[0030] The band 14 is constituted substantially by a flat strip of elastomeric material that has a curved cross-section: more specifically, it is constituted by two substantially flat and mutually incident flaps (ideally perpendicular) joined by a curved portion.
[0031] According to a constructive solution of particular interest in practice and in application, the leaf 3 can comprise an internal lever system 15, which is controlled by a movement control element 16 that can be operated from the outside.
[0032] The lever system 15 is preset to move at least one slider 17 from an inactive configuration, at which it is accommodated substantially in a respective area of the perimetric border 4 of the leaf 3, to an active configuration, at which said slider protrudes with respect to the perimetric border 4 of the leaf 3 for the elastic hermetic forcing of the gasket 11 that surmounts it against a corresponding face of the frame 2.
[0033] The movement control element 16 that can be operated from the outside can be connected to a dedicated handle provided on the face of the leaf 3 that is directed toward the inside of the installation space. However, the possibility is not excluded to adopt servomechanisms intended to actuate the control element 16 and/or to interconnect mechanically said control element to the lock 8 in order to ensure that the transition from the inactive configuration to the active configuration can be provided simply by moving the key to a predefined position.
[0034] According to a constructive solution that is particularly interesting on a practical level, the at least one slider 17 preferably can have an angular shape. In this case, it is accommodated along the perimetric border 4 of the leaf 3, at a corner thereof. The advantage of this embodiment is linked to the fact that in traditional doors the infiltrations of air (or also of water, the containment of which is also specifically prescribed by the statutory provisions in force) occur predominantly at the corners of the leaf 3: the forcing of respective angular sliders 17, indeed at the corners, ensures that an optimum tightness to infiltrations of air (and/or water) is ensured in these regions.
[0035] It is specified that, when reference shall be made hereinafter to air infiltrations, one shall consider that the solutions adopted to contain these infiltrations shall also have the purpose of avoiding infiltrations of water and/or wind and/or combined infiltrations. Therefore, one may speak of technical solutions aimed at avoiding infiltrations of the type defined by the acronym AWW (Air, Water, Wind).
[0036] It is specified, moreover, that the gasket 1 (in particular the elastomeric profile starting from which it is provided) is made of elastomeric material with shape memory, i.e., material adapted to assume the initial configuration even after it has been subjected to a long-term deformation. This type of material is used already to provide gaskets that are typical of other technological sectors and is instead an absolute novelty in the field of reinforced doors. It is evident that such materials allow to ensure that tightness to air infiltrations persists over time and remains substantially constant throughout the life of the door 1.
[0037] It is deemed useful to specify that the curved band 14 has the tip substantially aligned with the lateral profile of the main body 12.
[0038] This particular shape ensures that, upon contact of the lateral edge of the main body 12 with an abutment surface 18, a portion of the band 14 also abuts against the abutment surface 17.
[0039] At this arrangement of abutment on the surface 17, between the band 14 and the main body 12 there is a closed compartment 19 that constitutes a hindrance for air infiltrations.
[0040] It is useful to point out that in order to increase tightness to air infiltrations and therefore the thermal and acoustic performance of said door 1, the leaf 3 comprises preferably two substantially mutually opposite gaskets 11, i.e., provided with oppositely oriented bands 14.
[0041] Upon closure of the leaf 3, with its juxtaposition against the frame 2, each band 14 is therefore forced on a respective abutment surface 17 with a thrust that depends on the pressure, caused by any drafts, that is present upstream of said band 14. In practice a path for sealing against air infiltrations is provided in which, if an unwanted infiltration occurs at one of the two gaskets 11 that are present, the shape of the other gasket is such as to increase the force with which the respective band 14 is pushed against the respective abutment 17 following the increase in pressure upstream thereof caused by the above cited air infiltration. Therefore, this constructive solution ensures a considerable reduction of air infiltrations, up to the their total elimination.
[0042] With the goal of achieving the aim and objects defined earlier, it is specified that in the door 1 according to the invention at least one component of the leaf 3 and/or of the frame 2 comprises at least one outer covering layer constituted by insulating paints.
[0043] Likewise, at least one internal cavity of the leaf 3 and/or of the frame 2 accommodates a thermal insulation material that is inserted therein by means of a process such as blowing, dry spraying and the like.
[0044] It is useful to specify that the insulating paints used in the door 1 according to the invention comprise, in a dispersion, at least one substance selected among particles of insulating oxides, ceramic nanospheres, ceramic micro- and nanobubbles, micro- and nanobubbles of oxides, and the like.
[0045] Merely by way of nonlimiting example, some paints that are already commercially available and can be used to provide the outer layer defined earlier are the following: Nansulate®, which is a water-based breathable paint that covers completely any structure, creating a very thin but tough barrier to the passage of heat, is highly resistant to mold formation, is impermeable to water and breathable and utilizes the presence in a dispersion of patented nanomolecules (hydro-NM-oxide); SurfaPaint-ThermoDry™ Metals, which is a water-based and water-repellent thermal insulation paint for metals; NanoceramiX™, which is a mixture of ceramic nanospheres that is formulated to be added to ordinary paints, and in which the ceramic nanospheres have an internal void similar to that of thermos flasks; EcoThermoPaint™, which is an eco-active, thermally insulating, natural mold-resistant paint, which sanitizes and ionizes air and uses insulating hollow ceramics and mineral salts which create a barrier against adhesion to the surfaces of all organic and inorganic particles.
[0046] It is specified moreover that in order to define the criteria for acoustic and thermal insulation of predominant interest for the applicant, the thermal insulation material comprises at least one material selected preferably among cellulose fiber, aerogel, sintered expanded polystyrene, expanded polymers.
[0047] It is fundamental to specify that according to the invention the thermal insulation material has deeply different characteristics with respect to what is already in use in doors of the traditional type: it is in fact known to resort to panels made of expanded polymers or rock wool or glass wool that are used to fill all the cavities that are present inside the door.
[0048] The thermal insulation material according to the invention is instead inserted within each hollow component or in each receptacle that is defined by two or more mutually facing components. This constructive choice eliminates most of the thermal bridges that are present inside the leaf 3 and the frame 2 and minimizes heat and sound transmission coefficients.
[0049] Merely by way of nonlimiting example, some thermal insulation materials that are already commercially available and can be used to fill said cavities are the following: cellulose fiber (preferably stabilized), which is a loose thermal and acoustic insulation material that is particularly suitable for the thermal insulation of interspaces, is permeable to water vapor and has excellent sound absorption and soundproofing abilities, suppressing the reverberation of noise; Aerogel Spaceloft®, which is a silica gel that is manufactured synthetically and is impregnated with a substrate of flexible fabric that constitutes a flexible insulating cladding made of nanoporous aerogel that is capable of reducing energy dispersion even if it is applied with minimal thicknesses; granules of virgin or regenerated expanded polystyrene, which is a product with a uniform distribution of dimensional percentages, with substantially no water absorption and which allows even considerable reductions in transmitted noise.
[0050] In any case, combining the adoption of insulating paints and/or thermal insulation materials is not excluded, even using optionally other types of paints and materials (different from the ones cited) and/or by combining them with other insulating layers.
[0051] For this purpose, mention is made of the possibility to provide the outer coatings of some components of the door 1 with laminas made of insulating materials; for example, provisions are made for resorting to the Spaceloft® insulating felt (and/or materials that are equivalent thereto), glued by means of the respective bio-adhesive (and/or substances equivalent thereto) for the cladding of several components.
[0052] In relation to the interest in providing a reinforced door 1 that constitutes an excellent shield against heat flows and sound waves, all the components of the leaf 3 and of the frame 2 comprise at least one outer cladding layer, which is constituted by insulating paints, and all the internal cavities of the leaf 3 and of the frame 2 accommodate a thermal insulation material that is inserted therein by means of a process such as blowing, dry spraying and the like.
[0053] Blowing is a method by means of which it is possible to "blow" a material until a "container" is filled completely.
[0054] This term indicates the method of inserting some loose thermoacoustic insulation materials, such as flakes of wood cellulose and the like, within cavities.
[0055] Correct blowing entails: complete and uniform filling of the cavity to be insulated, formation of a self-supporting insulating element that does not empty itself as a consequence of a hole in the container, the absence of waste, the continuity of the layers of insulation and therefore the elimination of thermal bridges.
[0056] It is specified that the internal stiffening elements 6 are provided with holes or openings that allow the blowing of thermally insulating material.
[0057] If the internal elements 6 are mutually coupled slats, it is possible to use the areas where one slat is joined to the other for blowing if one does not wish to provide adapted holes.
[0058] If instead the elements 6 are constituted by tubular profiles that are mutually interconnected so as to constitute a grating, they must comprise respective holes that allow the blowing of insulating material.
[0059] The tubular profiles that constitute the grating described above can be mutually interconnected by using shape matings, so as to minimize the welding interventions to individual tack welds (localized welds).
[0060] In order to optimize the mutual alignment of the leaf 3 and the frame 2, the at least one hinge 10 in turn comprises at least one plate 21 that can be coupled detachably to a respective upright.
[0061] It will be seen hereinafter that the hinge 10 is adjustable according to four different axes, allowing optimum adjustment of the mutual position of the leaf 3 and the frame 2 even in conditions of installation on openings in the respective wall that do not have ideal measurements and alignments.
[0062] The plate 21 is provided with at least one hollow protruding block 22 for the pivoting of a slider 23 for supporting the hinge 24. The other articulated wing 20, which is coupled to the leaf 3, is connected to the hinge 24.
[0063] It is appropriate to point out that means for adjusting their mutual arrangement are provided between the plate 21 and the slider 23.
[0064] As mentioned earlier, the seal of the gasket 11 is dependent upon meeting predefined conditions of mutual alignment of the leaf 3 and the frame 2 that arise from the mutual arrangement of the plate 21 and of the slider 23.
[0065] It is particularly important that the upright of the frame 2 comprises a rear profile 25, which is coupled stably to the installation wall, and a front profile 26, which can be mated with the rear one 25, delimiting a compartment.
[0066] A corner support 27 can thus be coupled rigidly to the rear profile 25: said angular support is provided with respective threaded seats. The plate 21 comprises four slots 28, with a substantially angular shape that comprises two substantially rectilinear incident portions that are mutually blended.
[0067] The arrangement of the slots 28 is substantially complementary to the arrangement of the threaded seats of the angular support 27 for its mating, with an adjustable arrangement, to said support by means of threaded elements.
[0068] The slider 23 in turn is constituted by a band that is folded in a U-shape and is provided, on the two facing portions 29, which are mutually opposite at a mutual distance that is slightly larger than the length of the hollow protruding block 22 of the plate 21, with a through channel 30.
[0069] In the configuration for use, a connecting pivot 31 is accommodated simultaneously in the through channel 30 and in the cavity of the protruding block 22: it is specified that according to a preferred constructive solution the through channel 30 and the cavity of the block 22 are threaded identically.
[0070] The connecting pivot is constituted preferably by a screw whose diameter and thread are complementary to those of the through channel 30 and of the cavity.
[0071] It is specified furthermore that the block 22 further comprises further at least one threaded transverse hole 32 that leads to the internal cavity to accommodate at least one respective locking grub.
[0073] The slider 23 comprises at least one threaded duct 33, which is perpendicular and oblique with respect to the through channel 30, in order to accommodate a respective threaded pin 34, the end of which abuts against the plate 21.
[0074] The rotation of the pin 34, which corresponds to its screwing and unscrewing, in the respective duct 33, adjusts the arrangement of the slider 23 with respect to the plate 21 for the consequent spacing and approach of the threaded duct 33 with respect to said plate 21, imposed by the threaded pin 34.
[0075] According to the constructive solution of predominant practical interest, the threaded ducts 33 and 35 are two in number; the threaded pins 34 and 36 are engaged in said ducts 33 and 35.
[0076] The screwing/unscrewing of the pins 34 and 36 entails a rotation of the slider 23 with respect to the plate 21, with consequent movement of the hinge 24.
[0077] Likewise, the fixing of the plate 21 to the corner support 27 can also occur according to a plurality of different adjustable configurations by way of the particular shape of the slots 28.
[0078] It is appropriate to specify that the hinge 24 comprises means for adjusting the accommodation height of the pivoting stem of the leaf 3.
[0079] It has thus been shown that thanks to the many possibilities of adjustment ensured by the hinge 10 according to the invention it is certainly possible to arrange the leaf 3 in correct alignment with the frame 2, so that the gasket 11 can be in the ideal configuration during the use of the door 1, avoiding air infiltrations.
[0080] Advantageously, the present invention solves the problems described earlier, proposing a reinforced door 1 that avoids drafts as a consequence of an excellent seal of the corresponding gaskets 11, which depends on the correct alignment of the leaf 3 and of the frame 2.
[0081] Efficiently, the reinforced door 1 according to the invention is simple to install while ensuring an optimum thermal and acoustic seal, even if the frame has been installed on the respective opening without complying strictly with the parameters prescribed by the manufacturer.
[0082] Conveniently, the reinforced door 1 has a modest thermal transmittance, thus insulating thermally in an optimum manner the installation space with respect to the outside.
[0083] Positively, the reinforced door 1 has good sound insulation, thus insulating acoustically in an optimum manner the installation space with respect to the outside.
[0084] Advantageously, the reinforced door 1 has substantially low costs, is relatively simple to provide in practice and is safe in application.
[0085] The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims; all the details may further be replaced with other technically equivalent elements.
[0086] In particular, suitable architectural elements 100 are adopted to provide the threshold below the leaf.
[0087] These elements 100 are inserted in the floor and cause an interruption of the flooring with consequent blocking of heat flows.
[0088] These elements 100 are preferably made of metal profile or folded metal plate, which can be coated with paints among the ones cited earlier. The compartment 101 inside the element 100 is filled (preferably by blowing) with the thermal insulation materials described earlier.
[0089] The presence of a flap 102 that is folded inwardly to interrupt any heat flow through the walls of said element 100 is provided from the outset.
[0090] In the examples of embodiment shown, individual characteristics, given in relation to specific examples, may actually be interchanged with other different characteristics that exist in other examples of embodiment.
[0091] In practice, the materials used, as well as the dimensions, may be any according to requirements and to the state of the art.
[0092] Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
