Description

DESCRIPTION

The present invention relates to a window or a window glazing such as a breathing structure, comprising: - a first frame suitable for securing an opening function, comprising an outer notch for an outside glazing, and an inner longitudinal groove for an interior pane enclosing an air gap between the latter, - a second frame suitable for securing a frame function in which the first frame is intended to be positioned in a closed position of a window, - means for establishing a fluid connection between the air chamber and the exterior, at least in said closure position, comprising at least one fluid passageway in which one end opens onto a surface of the first frame in contact with the outer wall and the other end opens into the air chamber. The prior art teaches about such windows, or glazed balcony doors. Generally, this type of window or balcony glass door of said breathing structure relates to stop-gap or swing-stop windows, and offers multiple possibilities in terms of thermal, phonic, or light insulation. For example, in the air chamber between the said external pane and the said inner pane, we can place a light concealment means, namely a roller shutter. By the term "bay windows", "bay window" means all bay windows or doors in which the opening is mobile, or in which the opening has been definitively fixed in the closed position, and / or in which the external and / or interior was replaced by a concealing panel. The bead is said to breathe in order to allow the air chamber a fluid relationship with the exterior, that is to say by definition with the environment situated on the side of the pane or said outer panel, avoiding an air circulation crossing the surface of the chamber comprised between the two interior and exterior glazing. In use, current such windows or glazed balconies separating the interior and exterior of a building, and the fluid relationship of the inner chamber with the outside essentially allows a balance of the air chamber pressures, and prevent or attenuate the rich inside it. The inner pane may be a double glazing for good thermal insulation, and the outer glazing may be a single thick pane for good sound insulation of the window or glazed balcony door.

More particularly, documents FR 2784709 or FR 2784710 are known which describe such windows with breathing structure. These windows comprise, according to FR 2784709, on the one hand, in the frame of the aperture, at least one passageway or an orifice disposed in the range of the exterior and interior glazing to allow the pressure balance between the glazing and the exterior zone and, on the other hand side, in the frame, at least one passage or orifice which places said inter-glazing zone sufficiently in communication with the exterior of the window to establish this pressure or air circulation equilibrium. According to the document FR 2784710, said at least one passage or hole disposed in the opening frame opens into the inter-glazing zone and in a peripheral chamber that is delimited by the opening frame and the frame, this peripheral chamber communicating by means appropriate to the environment outside the window. Another window of breathing structure is known from EP-A-1403461. This document describes all the features of the preamble of claim 1.

Such windows or glazed doors with breathable facades have the drawback that they require specific fabrications and impermeability in the notch between the aperture and the frame. Moreover, such a breathing structure device has the drawback of interacting with the hardware and drains of the breathing frame. It should be noted that the routing of the orifices or breathing passages is long and complex, thus causing loss of charge and being compensated for by sections of greater fluid passage. The present invention aims to mitigate these drawbacks and bring other advantages. More precisely, it consists of a window, a window glazing, or the like, said breathing structure, comprising: a first frame capable of securing an opening function, comprising an outer notch for an outside glazing and an interior notch for an inner pane enclosing an air chamber between the latter, a second frame capable of securing a frame function in which the first frame is intended to be positioned in a closed position of the window, a balcony glazed door or the like, means for establishing a fluid connection between the inner tube and the outer one, at least in said closure position, comprising at least one fluid passageway in which one end opens onto a surface of the first frame in contact with the outside, and wherein the other end opens into the air chamber, characterized in that: - said at least one fluid passage is formed in a profiled gasket and wherein said window, a balcony glazed door, or the like comprises: - a peripheral impermeable gasket of said air chamber, composed of a first half-seal fixed to an inner profile of said window and a second half-seal integrated in said profiled seal on a low transverse support bracket of the external glazing - said profiled seal in a low maintenance pane of the exterior glazing comprising at least one aperture, said at least one end a fluid passage opening on a surface of the first frame in contact with the outside, and opening outwardly on a vertical face of the profiled seal in a low transverse support bracket of the exterior pane, above the second frame. Establishing a direct breath through the aperture allows to avoid having to work or fabricate the frame, and simplifies the breathing device by rendering it more direct. The window according to the invention has, among others, the advantage of having no need of matching, i.e. adjusting for the breathing device, between the aperture and the frame. The window according to the invention provides a more outward breathing possible by the fact of a passage through the aperture between the chamber and the outside. The window according to the invention makes it possible to avoid all the manufacture of the frame relative to the breathing device, from where a simplification of manufacture and thus in particular a gain in manufacturing time and a decrease in the risks of imperfection. The window according to the invention has the advantage that it does not require any impermeability between the aperture and the frame, nor any manufacture nor any impermeability in the notch between the aperture and the frame. The fluid passageway formed in a low-profile profiled gasket supporting the external glazing makes it possible to avoid working the frame of the aperture therein to form the breathing passages or to work the glazing and thus simplify the manufacture of the latter by locating the fluid passages in the gasket of the glazing, more particularly the inner horizontal joint. Such a configuration allows delivering the breathing principle under the control of the range supplier, that is to say of the creator of the window who knows all the elements to be taken into account for determining the breathing data. It is called a peripheral impermeability seal of the air chamber, the joint composed of half-joints forming peripheral impermeability against the surfaces of the glazing internal to the air chamber, between them, the fluid passages that communicate the air chamber with the the external waterproofing function being determined and not impeding the peripheral waterproofing function, such waterproofing must exist in the presence of fluid passages, in particular with a view to suppressing an air circulation which will be able to pass through the air chamber in its height, and also in view of to allow control of said fluid breathing passages from the air chamber, for example to filter the air entering the chamber.

According to an advantageous feature, said profiled low-profile support beam of the external pane comprises support means of the outer pane.

This enables to ensure the continuity of the breathing flow through the fluid passages by avoiding a crushing of the gasket under the weight of the glazing assumed by the support means, for example in the form of chocks welded to the end of the gasket on the underside of the aperture.

According to an advantageous feature, said profiled low-profile support member of the outer pane comprises the anti-dust filter means.

The anti-dust filter means incorporated in the interlayer allow the filter to be replaced with a view to the support in order to always ensure the breathing function of the air chamber, advantageously without dismantling the replacements (glass panes or the like), allowing to avoid the main impermeability of the breathing structure. By means of an anti-dust filter, the filter of the known type is understood here, also ensuring in particular the function of preventing the insects from penetrating into the air chamber, and more broadly not being reactive to moisture and advantageously being able to ensure a function of attenuation.

The filters may advantageously be a key element of the product by integrating a particular aesthetic, for example by conveying the technicality of the product and a trademark.

According to an advantageous feature, said lower pane-shaped profiled seal of the outer pane adopts a deep section, said outer pane support means being inserted in the bottom profile of the gasket, in at least two locations along the length of said gasket profiled in low beam. 4

According to an advantageous feature, said profiled low-profile support member of the outer pane comprises an advanced one intended to prevent the penetration of water by at least one aperture opening on a surface of the first frame in contact with the outside.

According to an advantageous feature, said profiled low-profile rail profile support of the outer pane has a generally rectangular section, the upper part of which has a housing capable of receiving an edge of the outer pane.

According to an advantageous feature, said housing is provided with inner and outer impermeability lobes intended to come into contact with the exterior pane.

According to an advantageous feature, a horizontal dimension of the rectangular section of the profiled seal is determined so as to have a face-to-face surface of the periphery of the air chamber, said surface comprising at least one aperture forming the end of at least one fluid passage opening in the air chamber, said surface entering into the constitution, with the inner lobe of the housing in abutment against the inner surface of the inner pane, of the complementary sealing half of the half-joint in order to form the sealing joint peripheral

According to an advantageous feature, said at least one fluid passageway develops in an interior space of the profile section of the low-pane support beam of the outer pane under a wall of said section forming said surface comprising at least one aperture and a housing able to receive an edge of the outer pane.

According to an advantageous feature, the low profile pane of the outer pane support comprises an internal arrangement, defined by a suitable shape of the hollow section of said joint, by means of a rib and / or guard, in order to allow sliding and place a filter running on the wire over the openings.

According to an advantageous feature, the low profile support of the external glazing support comprises, on its external vertical face, a continuous impermeable lobe over the length of the profiled joint, intended to come into contact with the frame when the aperture is closed.

Further features and advantages will appear from the following reading of an example embodiment of a window, bay window or analog structure of breathing structure according to the invention, accompanied by the accompanying figures, for example by way of non-limiting illustration. Figure 1 is a vertical cross-sectional view of the bottom of a breathing structure window of the prior invention. Figure 2 shows a vertical cross-sectional view of the bottom of an exemplary embodiment of a breathing structure window according to the invention.

Figures 3 and 4 show details of figure 2. Figure 5 is a horizontal cross-sectional view of the side of a window according to the invention, and according to the example of figure 2. The window of the prior invention represented by figure 1 comprises: a first frame 1 capable of securing an opening function, comprising an outer notch 26 for an outside pane 2 and an inner notch for an inside pane 3 enclosing an air chamber 4 therebetween, a second frame 5 suitable for securing a frame function in which the first frame is intended to be positioned in a closed position of the window, position shown in figure 1, means 6 for establishing a fluid connection between the inner chamber 4 and the outside 7 in the closed position.

As explained above, the means 6 for establishing a fluid connection between the inner tube 4 and the outer tube 7 comprises passages 8 traversing the first frame 1 of the aperture 16 and the second frame 5 or frame, these passages 8 comprising at least one channel 10 fixed to the frame, opening at one end over an aperture 12 of the lower profile of the frame, and intended for the other end to correspond to an aperture 11 formed in a profile 15 of the aperture 1, which supports the outer notch 26 in which is housed the the aperture 11 being in fluid communication with the air chamber 4, as shown in Figure 1, through a passage 14 in the aperture through a sealing gasket 13 of the air chamber 4 and the profile 15 of the aperture at the bridge rupture forming part of the opening frame 1 and in contact with the frame, as shown in figure 1 in the closing position of the window. The window partially shown in Figure 2 retrieves prior art elements similar to those in Figure 1 in order to make the invention of the prior invention better known. These elements of figure 2 functionally similar to those of figure 1 carry the same numerical reference number 400. The window shown in figure 2 comprises: a first frame 401 suitable for securing an opening function, comprising an outer notch 426 for a window pane 402 and an inner notch for an inner pane 403 confining an air chamber 404 between the latter, a second frame 405 apt to provide a frame function in which the first frame is intended to be positioned in a closed position of the latter window, means 406 for establishing a fluid connection between the air chamber and the exterior 407, at least in the closed position, comprising at least one fluid passageway 420 wherein one end 421 opens on a surface of the first frame in contact with the exterior , and wherein the other end 422 opens into the air chamber, said at least one fluid passageway 420 being formed in a junction the inner tube 404 is formed in the lower pane of support of the outer pane 402, a peripheral impermeability seal 413 of the inner tube 404, composed of a first half-seal 452 fixed to an inner contour 428 of the first frame 401, and by a second half- seal 453 integrated in the seal 450 profiled on a lower deck of support of the external glazing 402, said seal 450 profiled on a low deck of support of the external pane 402 comprising at least one opening 421, the end of said at least one fluid passageway 420 opening and on the exterior face 407 on a vertical face of the gasket 450 profiled on a low deck of the outer pane supporting above the second frame 405 as shown in figure 2.

As shown in Figure 1, the frame 401 of the frame 416 comprises in a known manner an inner profile 428 and a thermal bridge breaking outer profile 451 secured to the inner profile 428, as shown in Figure 2. The profile 451 will be described more precisely below .

It will be appreciated that with such a device, the breathing function became independent of the aperture bearing frame comprising the thermal bridge rupture profile 451 and the internal metal profile 428 and the frame 405 to be confined at the level of the profiled joint 450 in the lower support pillar of the outer pane 402. The breathing of the inner tube is ensured that the aperture is in the open or in the closed position on the frame. It should be noted that the window according to figure 2 may or may not contain impermeability 460 between the aperture 416 and the frame 405, the latter 404 of which may, if necessary, properly and known water evacuation holes 435 be known. The exemplary embodiment of a window according to the invention shown in Figures 2 to 4 differs essentially from the example of the previous invention according to Figure 1 in which the fluid passages 420 are formed in a low profile deck profile 450 formed in the support of the outer pane 402 In order to improve understanding of the invention, the window partially shown in Figures 2 and 5 takes up similar prior art elements to those in Figure 1. These elements of Figures 2 and 5 functionally similar to those in Figure 1 carry the same increased numerical reference number 400.

Thus, the essential differences between the example of Figure 2 and that of the prior invention of Figure 1 reside: in the absence of any passage or breathing conduit of the air chamber 404 passing through the frame 405, as well as the space 425 comprised between the frame 405 and aperture 416 in the advantageous absence of the entire passage or breathing conduit of the air plenum 404 passing through the thermal bridge rupture profile 451 of the frame 401 of the aperture 416 in the advantageous presence of fluid passages 420 formed in a profiled gasket 450 in the specific outer support pane of outer pane 402 as above and below explained, according to an essential means of the invention, in the modification of the peripheral impermeability seal 413 of the air chamber 404, which is presently composed of a half-joint 452 fixed to the profile 428 of the frame 401 of the aperture 416, and a half-seal 453 integral with the gasket 450 profiled in a lower deck support bracket of the external pane or 402, in a modification of the outer thermal bridge breaking profile 451 of the frame 401 of the aperture 416, the outer profile 451 adopting a shape suitable to receive the profiled low profile support gasket 402 of the outer pane 402, as will be explained below, The gasket 450 profiled on a lower support pane of the outer pane 402 fits a generally rectangular shaped section, the upper part including a housing 454 capable of receiving the pane, said housing 454 being provided with inner impermeability lobes 471 and exterior 472 intended to come into contact with the outer pane 402, the horizontal dimension of the rectangular section of the profiled gasket 450 being determined so as to have a surface 455 relative to the periphery of the air chamber 404, this surface 455 having breathing apertures 422 of the plenum chamber 402, air and into the constitution, with the inner lobe of the housing 454 in abutment against the inner face r of the inner pane of the impermeable half-seal 453 complementary to the half-seal 452 in order to form the peripheral seal 413. The vertical dimension of the rectangular section of the profiled seal 450 is determined in relation thereto in order to allow the passage of fluids 420 of sufficient section for breathing of the air chamber 404 in which the or the outward openings 421 open outwardly 407 on the vertical face of the seal 450, above the abutment 405, more precisely above the stop of the frame 405 that enters in contact with the closure opening of the latter, as shown in Figure 2. The joint 450 will advantageously feature a shoulder 456 intended to prevent water penetration by the or the apertures 421, as shown in Figure 2. The shoulder 456 may be continuous over the length of the joint 450. As shown in Figures 2 or 4, the housing 454 intended to house one side of the exterior pane may adopt a cross section The fluid passages 420 are developed in the interior space of the joint section 450 under the wall of said section forming the surface 455 and the housing 454 in U or V.

As shown in Figure 2, the outer thermal bridge rupture profiling 451 of the frame 401 of the aperture 416 assumes a section suitable to allow a fastening of the gasket 450 formed in a low through-beam and / or anchorage, as shown in Figure 2. A such a configuration permits a breathing aperture of the plenum 404 at the bottom thereof without having to make a breathing hole in the peripheral impermeable half-seal 452, or the peripheral impermeable gasket 13 of the prior invention. The low-profile profiled seal 450 may for example assume a hollow section, as shown in figures 2 or 4, support members 457 able to support the weight of the outer pane 402 and are then inserted into the hollow profile of the joint 450, for example by over-fitting , in at least two locations of the length of the joint 450, in order to prevent crushing of the latter under the weight of the pane 402 and thus ensure sufficient cross-section of the breathing passages 420 of the air chamber 404. The cross-section of such gasket 450 can adopt walls of constant thickness as shown in Figures 2, 4 and 5.

In addition, an anti-dust filter 433 may at least be advantageously inserted in the gasket 450, for example under the aperture 422 opening into the air chamber, as shown in Figure 2. The anti-dust filter means 433 is advantageously disposed through the fluid passages 420, preferably against the apertures 422 of the gasket 450, as shown in Figure 2. The filter 433 may advantageously be a movable filter, namely of the known mechanical stainless steel filter type, which allows not only to stop dust but also more widely insects so that all such objects do not penetrate the air plenum 404. An internal arrangement of the gasket 450, by a suitable shape of the hollow section of the latter, by means of rib 480 and / or carrier 481 for example, may be made to allow to slide and hold in place a threaded filter 433 under the apertures 422 of the gasket 450, as shown in Figure 2.

The openings 422 and 421 may for example be obtained by molding the joint, and for example adopting a circular passage section. Figure 3 shows an example of a rigid support member 457 in the form of a profiled section securing the joint height 450 with the upper pane support by V-shaped ribs as shown, and the width of the joint 450 in order to ensure a rigid fixation of the latter over the thermal bridge rupture profile 451. The rigid support member (s) 457 will not be aligned with the apertures 422 and 421 in order to ensure free passage thereof.

Alternatively, the low profile profiled seal 450 may assume a flat section (not shown) in which ducts are traversed through to form the fluid breathing passages 420 of the air plenum 404. A planar section of the seal 450 could be sufficient to withstand the weight of the pane under a sufficiently weak deformation to ensure the cross-section of the fluid passages, but it is possible to provide for securing the said fluid passages with a rigid sleeve. The profiled gasket 450 in low cross-section with a flat cross-section may comprise the entire rigid insert giving it a rigidity appropriate to its attachment. The gasket 450 may be provided on its outer face against the frame stop 405 when the aperture is in the closed position, an impermeable lobe 460 continues over the length of the gasket 450, intended to come into contact with said stop when the aperture is closed as shown in figure 2. The half-seal 452 secures the impermeability between the inner tube 404 and the inner side of the window by means of a fastening in the inner profile 428 of the opening frame, for example by engagement as shown in figure 2 or 4. The half-seal 452 ensures the impermeability of the air chamber 404, in cooperation with the half-seal 453 of the seal 450, at the level of the junction of these two half-joints, for example at a distance equal to the surface interior of the outer pane 402 and the inner surface of the inner pane 403 as shown on figure 2 or 5. The impermeability between the two half-joints 452 10 and 453 was made by the contact of the latter in a plane parallel to the glazing, as shown in figures 2 and 5.

On Figure 5, a horizontal cross-section of the window of Figure 2 depicts the low-profile profiled seal 450 replaced by an inner medial impervious profiling 459 and an external sill 458 securing all two in combination with the external glazing holder 402. This The configuration according to figure 5 is in vertical section of the upper part of the aperture (not shown). The inner medial impermeability profile 459 adopts a shape which is close to that of the joint 450, intended to fill the space between the inner surface of the outer pane 402 and the inner profile 428 of the aperture 416, and to ensure the impermeability of the air chamber 404 , in cooperation with the impermeable seal 452, to form the peripheral impermeable seal 413. The structure of the impermeable profiling 459 may for this purpose adopt for example a substantially rectangular tubular cross-sectional shape bearing at an exterior angle of the section, an integral lobe seal intended to be applied against the inner surface of the outer pane 402 to make impermeable therewith as shown in Figure 5. It should be noted that the impermeability profile 459 does not contain U- or V-shaped housing 454 nor fluid passage 420. Contrary to the seal 450, the impermeability profiling 459 is entirely disposed between the two inner panes 403 and outer 402 and has no part in direct contact with the exterior 407. The outer thermal bridging profile 451 of the aperture 416 may assume an identical section on the four sides of the aperture. The lateral and upper outer pane fixation sill 458 may be in any known manner and suitable to be aligned with the joint 450. This sill 458 may be provided with a seal of impermeability 465 covering its outer surface, as shown in the figure 5, in order to form, by means of a single monoblock joint associated with the sill, an impermeable seal against the frame stop in the position of the closure of the aperture. The low-profile profiled seal 450, such as the impermeability profiling 459, and the half-seal 452, may be made of plastics of the rubber or the like type, for example an EPDM, molded, extruded, etc. rubber.

The constituent profiles of the inner and outer frame 405 are generally in metal alloy or in plastic materials, separated by thermal bridge rupture indents in the case of the use of metal alloy, and the constituent profiles of aperture 416, interior 428 and exterior 415 , can be respectively metal and plastic, in order to obtain thermal bridge rupture profiles for the frame and the aperture. The invention applies to the entire window, or glazed balcony door, called the breathing structure.
