Description

Field of application

[0001] The present invention refers to a door/window, according to the preamble of the main independent claim.

[0002] The present finding is intended to be employed in the field of production of doors/windows and in particular for obtaining windows, French windows or glass doors/walls.

State of the art

[0003] According to the conventional art closest to the present invention, the doors/windows have a door/window assembly with a glass panel composed of multiple parallel sheets, two-by-two spaced from each other by channels, adapted to define corresponding double glazing capable of improving the thermal insulation of the door/window.

[0004] The door/window assembly also comprises a frame, made of metal, wood or plastic material, which is perimetrically associated with the panel during installation in order to support it with respect to a frame integral with the walls of the building.

[0005] The interconnection between glass panel and frame has in practice shown to be difficult to obtain and rather costly, so that recently doors/windows have appeared in the market in which the panel is mechanically perimetrically associated to the frame, already during the production process.

[0006] Such new doors/windows arose also to meet the need of arranging at least one lateral sheet of the panel completely in view, with the perimeter edge that completely conceals the side of the frame, without it being visually possible to see the engagement of the panel inside a seat of the frame.

[0007] An example of a door/window of known type indicated above is for example described in the patent DE 10119640.

[0008] In addition, known from the patent EP 1528213 is a door/window provided with a door/window assembly having a glass panel comprising an internal sheet, an external sheet and a central sheet, and a frame perimetrically fixed to the glass panel.

[0009] Such frame is composed of a first section with rectangular section fixed between the two lateral sheets, on the lower part of the central sheet and in part on the lower part of the two channels, and of a second section, with width larger than the first and against which a lateral glass of the panel abuts.

[0010] The door/window of known type described above has shown that it does not lack drawbacks.

[0011] A first drawback lies in the fact that the frame is composed of multiple sections which require difficult operations for their interconnection and which do not allow obtaining a door/window of high quality.

[0012] A second drawback derives from the fact that the first section supports the glass in a far-from-optimal manner, given that its precise positioning is not provided with respect to the central glass. In particular, the load of the panel, discharging also on a lateral sheet of the panel, does not allow a centered support and determines the formation of moments that can create clearances or lead to breakage or cracks.

[0013] A third drawback lies in the fact that means are not provided for supporting the lateral glass sheets with respect to the central glass sheet outside of sealing glues, leaving the latter with the full stress of the weight force and hence of the consequent shearing moment with respect to the central sheet. Consequently, the sealing between glass plates must be selected with large thicknesses (e.g. greater than one centimeter) in order to support the weight itself of the plates with consequent increase of production costs.

[0014] A further drawback lies in the lack of systems for adjusting the glass panel with respect to the frame which, especially in the case of doors/windows with considerable size, can determine misalignments that negatively affect aesthetics as well as cause functional problems for the correct opening and closing of the door/window.

[0015] Doors/windows are also known, described for example in the patent DE 102009027297, in which the door/window assembly has the support frame of the panel forming part of the channels that space the glass sheets.

[0016] Such doors/windows require a complex production process and are not very versatile in the possibilities of production thereof, combining in an indissoluble manner the characteristics of the panel with those of the frame, in addition to not ensuring good mechanical performances and simultaneously good insulating seal performances, given that the two functionalities are assigned to the same frame. A further drawback of the doors/windows of known type mentioned above which employ a support frame for the glass panel constituted by a metal section is tied to the poor thermal insulation performances of the door/window. Indeed, the insulation performances are considerably compromised by the presence of the metal profile inserted between the external sheet and the internal sheet of the door/window, which form an undesired thermal bridge between the internal and external face of the door/window.

[0017] Known from the French patent FR 2701997 is a panel for continuous glass facades, which comprises a panel provided with three glass sheets rigidly fixed parallel to each other and comprising an external lateral sheet, an internal lateral sheet and a central sheet interposed between the lateral sheets and respectively separated therefrom by means of a first and a second channel adapted to define a corresponding first and second double glazing. A frame is provided that is perimetrically fixed to the panel and intended to support the latter with respect to the façade of a building. The panel is extended beyond the double glazing for a peripheral section. The frame is provided with two projecting shapes with pyramid form which are slipped between the pairs of glass sheets (i.e. between each lateral sheet and the central sheet) supporting the panel. The two shapes are separated by a perimeter seat in which the central sheet is inserted, however without the latter being fixed thereto and only abutting against a cord of insulating material that does not have a structural function.

[0018] Such panel solution has the drawback of providing for a frame that substantially extends beyond the perimeter edge of the glass sheets, all the sheets being projecting from the double glazing for a peripheral section of equivalent extension. In addition, the panel described in this French patent does not allow discharging the weight thereof on the frame through the central sheet.

[0019] Known from the German patent DE 102010005181 is a panel provided, also in this case as in the preceding panel of the French patent, with three sheets that are all projecting from the double glazing for a peripheral section of equivalent extension. An externally flat frame, unsuitable for being used as a door/window assembly in a door/window, is fixed to the glass sheets at the space outside the spacer channels of the double glazing. In substance, it is provided to use the silicone sealant of the double glazing also for fixing to perimeter frame. The frame of the panel projects beyond the perimeter ends of the sheets and is bulky and not aesthetically pleasing.

Presentation of the invention

[0020] In this situation, the problem underlying the present invention is that of overcoming the drawbacks manifested by the solutions of known type, by providing a door/window, which has a door/window assembly that structurally connects, in a mechanically resistant manner, the frame thereof to the glass panel thereof.

[0021] Further object of the present invention is to provide a door/window which is simple and quick to install and entirely reliable in operation.

[0022] Another object of the present invention is to provide door/window which allows insulating the internal environment from the external environment, ensuring a reduced thermal transmittance coefficient.

[0023] Another object of the present invention is to provide a door/window provided with a door/window assembly having at least one face with glass completely in view supported by the frame in a mechanically optimal manner.

[0024] Further object of the present invention is to provide a door/window which is quick and easy to obtain.

Detailed description of a preferred embodiment

[0026] In accordance with the figures of the enclosed drawings, the door/window that is the object of the present invention is indicated in its entirety with the reference number 1.

[0027] In the following present description, reference will be made to a door/window formed by a frame 3 and by a door/window assembly 100 of a window provided with a glass panel 2; nevertheless, it is intended that, without departing from the protective scope of the present patent, the door/window assembly 100 can be part of a French window, a skylight or another mobile door/window provided with a glass panel 2.

[0028] In particular, the embodiments illustrated in the enclosed figures refer to the preferred case, in which door/window 1 comprises a mobile door/window assembly 100 of a window rotatably coupled to a frame 3 intended to be embedded-anchored in a wall of a building.

[0029] In an entirely conventional manner, the frame 3 has the shape of a quadrangular frame, usually obtained with two uprights and two crosspieces, and defining a lying plane. Such plane is the installation plane of the door/window 1 and is provided with an internal side, i.e. directed towards the use space of the building, and with an external side, i.e. directed towards the external environment of the building.

[0030] In an entirely conventional manner, the door/window 1 can carry out the functions of separation, protection and insulation of rooms, also allowing the communication and visual contact between the external and internal environments, in addition to being adapted to facilitate the natural ventilation inside the rooms.

[0031] The glass panel 2 is supported by a frame 4 perimetrically fixed to the panel 2 and intended to support the latter with respect to the frame 3.

[0032] More in detail, the panel 2 is of the type formed by at least three glass sheets, of which one is an external sheet 5, one an internal lateral sheet 6 and one a central sheet 7 interposed between the aforesaid two lateral sheets 5, 6.

[0033] The three sheets 5, 6 and 7 are rigidly fixed parallel to each other along the perimeter thereof, by means of fixing means described in detail below, and are separated from each other by means of a first channel 8 interposed between the external sheet 5 and the central sheet 7 and a second channel 9 interposed between the internal sheet 6 and the central sheet 7. The aforesaid two channels 8 and 9 are positioned in proximity to the perimeter edges of the three glass sheets 5, 6 and 7.

[0034] The three glass sheets 5, 6 and 7, together with the two interposed channels 8 and 9, define between them a first and a second double glazing, respectively indicated with the reference numbers 10 and 11.

[0035] Preferably, the central sheet 7 is obtained with a tempered glass or with a stratified glass.

[0036] The fixing means mentioned above for fastening together the glass sheets 5, 6 and 7 are obtained with layers 12 of sealant material, placed next to the channels 8 and 9 on the external side of the double glazing 10, 11, i.e. towards the perimeter edge of the sheets 5, 6 and 7.

[0037] The aforesaid sealant material of the layers 12 is preferably of structural type, such as structural silicone. The thickness of such sealant layers 12 can advantageously have reduced size, e.g. 8-9 mm, since it must support shearing stresses due to the weight of the lateral sheets 5, 6 in a limited manner, since, as explained below, support plates for the lateral sheets 5 and 6 are advantageously provided.

[0038] The channels 8, 9 are preferably obtained with aluminum profiles, or with silicone bars, or with bars made of PVC reinforced with steel layers, and have the function of maintaining the sheets 5, 6, 7 spaced in addition to dehydrating the air contained in the double glazing 10, 11. For such purpose, they can contain hygroscopic salts at their interior, reachable by means of microholes suitably obtained on the surface of the channel directed towards the interior of the double glazing 10, 11, in order to absorb the moisture of the air that would otherwise condense on the internal walls of the sheets 5, 6 and 7.

[0039] According to the idea underlying the present invention, the internal lateral sheet 6 and the central sheet 7 of the panel 2 are extended perimetrically beyond the double glazing 10, 11 for corresponding peripheral sections 5', 6', 7', of which that relative to the central sheet 7' is shorter than those relative to the lateral sheets 5', 6' between which it is interposed, and preferably as an example such central sheet 7' has a height of about 10-20 mm.

[0040] Preferably, the internal lateral glass sheet 6 projects for a section 6' greater than the section 5' of the external lateral sheet 5.

[0041] In addition, the frame 4 comprises a central portion 21 and two lateral portions, of which one is internal 19 and one is external 20, substantially interposed between the peripheral sections 5', 6' of the lateral sheets 5, 6 and connected together by the central portion 21.

[0042] More in detail, the central portion 21 is provided with a perimeter seat 15 delimited by two parallel longitudinal walls 16 and by a bottom 17 placed to connect the longitudinal walls 16. The perimeter seat is associated with the structural sealing cord 18 and it is engaged by the peripheral section 7' of the central sheet 7, which is therefore embedded in the structural sealing cord 18 in order to support the panel 2.

[0043] The two lateral portions, internal 19 and external 20, are susceptible to mechanically collaborating with connection means 13 in order to angularly join together the uprights and the crosspieces of the frame 4.

[0044] Substantially, not only are the internal portions 19 and external portions 20 of the frame interposed between the peripheral sections 5', 6' of the lateral sheets 5, 6, but also the central portion 21 is interposed.

[0045] Preferably, moreover, if one excludes the ribs peripherally projecting in order to define supports of the door/window assembly 100 with the frame 3, the entire frame 4 results interposed between the peripheral sections 5', 6' of the lateral sheets 5, 6.

[0046] Of course, without departing from the protective scope of the present finding, the lateral portions 20, 21 can assume the most suitable form for being mechanically associated with the connection means 13. These are indicated as two separate lateral portions given that the frame 4 is extended from both sides of the central portion 15; nevertheless, such lateral portions can be seen as a single profile connected to a central portion 15. In addition, even only one of such portions (or such single profile) can be mechanically associated with the connection means 13.

[0047] For example, the lateral portions 20, 21 can be hollow and the connection means 13 can comprise small squares inserted in at least one of the aforesaid hollow lateral portions 20, 21.

[0048] Advantageously, the lateral portions 20, 21 mechanically rest on the opposite internal faces of the peripheral sections 5', 6' of the external lateral sheet 5 and the internal lateral sheet 6 of the panel 2.

[0049] Of course, the lateral portions 20, 21 can rest directly on such peripheral sections 5', 6' with their walls facing the same peripheral sections 5', 6' or they can rest with the interposition of a sealant layer or with the interposition of support elements of the type described hereinbelow and indicated with the reference number 30.

[0050] Advantageously, the frame 4 of the door/window assembly of the door/window according to the invention comprises at least one longitudinal rib 41 which projects beyond the peripheral section 5', 6' of at least one lateral sheet 5, 6 in order to abut against a corresponding portion of the frame 3 of the door/window 1.

[0051] The frame 4, preferably obtained in an extruded plastic section, e.g. made of polyamide, PVC or an insulating composite material such as glass fiber, comprises two crosspieces of which one is lower 14 and one upper (not illustrated) and two uprights placed to connect the two crosspieces.

[0052] The central sheet 7 discharges the weight of the panel 2, i.e. also of the other two plates 5, 6, on the frame 4 in a middle position with respect to its cross section, at the aforesaid seat 15.

[0053] The unit of the door/window assembly 100 constituted by the panel 2 formed by the three plates 5, 6 and 7 and by the frame 4 is obtained during production, such that during installation of the door/window 1 it is sufficient to mount the support hardware of the door/window assembly 100 on the frame 3, such as hinges, in order to complete the mounting of the door/window 1 in a facilitated manner. Preferably, the peripheral section 7' of the central sheet 7 is extended projecting beyond the double glazing 10, 11 along the entire perimeter of the panel 2 (i.e. beyond the channels 8, 9 as well as beyond the corresponding sealant layers 12), it being inserted in the seat 15 of the frame 4, the latter also having a correspondingly perimeter extension in order to retain the aforesaid peripheral edge 7' on the entire perimeter and thus rigidly engage the panel 2.

[0054] The panel 2 abuts against the seat 15 of the lower crosspiece of the frame 4 at the lower side of the peripheral section 7' of the central sheet 7 and is engaged with the other sides thereof, lateral and upper, in the seat 15 obtained on the perimeter of the two lateral uprights and on the upper crosspiece of the frame 4; the panel 2 thus results firmly constrained to the frame 4 along the entire perimeter and hence with respect to the stresses transverse to the plane of the panel 2, due for example to the action of the wind.

[0055] Otherwise, but in a substantially equivalent manner, the door/window assembly 100 could provide for an extension of the peripheral section 7' of the central sheet 7 of the panel 2 and correspondingly of the seat 15 of the frame 4 only for one or more crosspieces and/or uprights of the door/window assembly 100.

[0056] The two hollow lateral portions 19, 20 mentioned above have perimeter extension, have preferably tubular form and have quadrangular section with right angles (in the figures, they have rectangular form), including an internal lateral portion 19, i.e. arranged at the internal face of the door/window assembly 100, and an external lateral portion 20, i.e. arranged at the external face of the door/window assembly 100.

[0057] Each hollow lateral face 19, 20 is arranged perimetrically to the outside of the space subtended between the two pairs of sheets 5, 7 and 6, 7 which define the two double glazings 10, 11, i.e. it is facing the relative sealant layer 12 of the corresponding double glazing 10, 11.

[0058] Preferably, in order to precisely define the rest position of the panel 2 on the frame 4, independent of the possible tolerances of the size of the central sheet 7 due to the production process, at least one abutment bracket 22 is provided fixed on the lower crosspiece 50 of the frame 4. Preferably, the lower crosspiece 50 is provided with two or more abutment brackets 22 of the panel 2 on the frame 4 (e.g. two) that are spaced from each other.

[0059] Each abutment bracket 22 projects from a corresponding opening 23 provided on the bottom 17 of the seat 15 and is adapted to receive, in abutment, the external edge of the peripheral section 7' of the central sheet 7.

[0060] The abutment brackets 22 allow precisely defining the position of the glass panel 2 with respect to the frame 4, i.e. with respect to the lower crosspiece 50 of the frame 4.

[0061] More in detail, the aforesaid abutment bracket 22 is provided with a base portion 24 connected with a shank 25 to an abutment portion 26 which projects from the opening 23 from the bottom 17 of the seat 15 in order to receive, in abutment, the external edge of the peripheral section 7' of the central sheet 7 of support for the panel 2.

[0062] Advantageously, the base portion 24 of the abutment bracket 22 is fixed to the external peripheral face 4' of the frame 4 by means of first fixing means constituted for example by at least one screw 27, by a rivet or by similar means.

[0063] Between the base portion 24 of the abutment bracket 22 and the external face of the frame 4, at least one spacer element 28 is interposed. The adjustment of the correct position of the glass panel 2 with respect to the frame 4 can thus be suitably carried out by varying the abutment position of the central sheet 7 on the frame 4, i.e. on the abutment portion 26 inserted in the seat 15.

[0064] The frame 4 is formed by two crosspieces and by two uprights mechanically connected together at the ends in order to form angular joints by means of small mechanical connection squares, which are inserted in engagement relationship in the cavities of the contiguous lateral portions 19, 20 of crosspieces and uprights to which the aforesaid small squares are advantageously fixed, e.g. by means of screws inserted in holes 40 obtained at the ends of the same portions of the uprights and the crosspieces of the frame 4.

[0065] In order to improve the mechanical solidity of the panel 2, i.e. the anchorage between the glass sheets 5, 6 and 7, at least one support element 30 can be advantageously provided, equipped with at least one support portion 31, intended to abut against the perimeter edge (the thickness) of the peripheral section 5', 6' of at least one lateral sheet 5, 6 and at least one anchorage portion 32 mechanically connected by means of second fixing means 33 to the frame 4.

[0066] In particular, in the case in which it is the external lateral sheet 5 of the glass panel 2 to be extended to cover the external lateral face of the frame 4, then the anchorage portion 32 of the support element 30 will be advantageously fixed by means of the second fixing means 33 to the external peripheral face 4' of the external hollow lateral portion 20 of the frame 4.

[0067] In accordance with an advantageous characteristic of the invention, the anchorage portion 32 has a step portion 34 with form analogous to that of the lateral edge 35 of the external lateral portion 20 of the frame 4 in order to obtain a form coupling that allows simultaneously defining both a precise positioning of the support element 30 on the frame 4 and a more solid anchorage of the same support element 30 to the frame 4.

[0068] In the case in which it is the internal lateral sheet 6 of the glass panel 2 to be extended to cover the internal lateral face of the frame 4, then the anchorage portion 32 of the support element 30 will be advantageously fixed by means of the second fixing means 33 to the internal peripheral face 4" (i.e. directed toward the corresponding double glazing) of the internal lateral portion 19 of the frame 4.

[0069] In accordance with an advantageous characteristic of the invention, in the latter case the support element 30 has a substantially Z-shaped form with the support portion 31 and the anchorage portion 32 substantially parallel to each other and joined by a connection portion 36. The latter is extended parallel to the internal sheet 6 of the panel 2, and is for one section thereof interposed between such sheet 6 and the internal lateral portion 19 of the frame 4.

[0070] Advantageously, a first and a second seal 37, 38 are provided, respectively interposed between the frame 3 and the projecting sections 5', 6' of the external 5 and internal 6 lateral glass sheets of the panel 2.

[0071] Preferably, the internal lateral glass sheet 6 projects for a section 6' greater than the section 5' of the external lateral sheet 5.

[0072] Preferably, the frame 4 is provided at the side thereof towards the inside of the building and on its external peripheral face 4' with a longitudinal groove 39 adapted to retain, in engagement relationship, the second seal 38, which is extended for a section behind the peripheral section 6' of the internal lateral sheet 6.

[0073] Advantageously, a longitudinal rib 41 is extended from the external peripheral face 4' of the external lateral portion 20 of the frame 4, such rib intended to receive in abutment a third seal 42 fixed to the frame 3 (and preferably to a protection frame 43 fixed to the external lateral face of the frame 3) and on which the door/window assembly 100 is intended to be closed.

[0074] The finding thus conceived therefore attains the pre-established objects.

[0075] Of course, in the practical attainment thereof, it can also assume forms and configurations different from that illustrated above, without departing from the present protective scope. In addition, all details can be substituted by technically equivalent elements and the shapes, size and materials used can be of any type according to requirements.
