Description

The present invention relates to a opening double glazing, equipped with means allowing the existing air gap, trapped between the two independent parallel windows that form this glazing, to be put in relation permanent and in balance of pressures with the outside atmosphere, in particular to avoid condensation phenomena or other on the faces windows opposite, these means being also arranged, because these two windows are not connected directly to one another to form a unitized unit sealed and sealed where the air gap would be totally confined, so as to facilitate assembly, maintenance and eventual repair of various accessories, of the genus store, screen pare sun, internal curtain etc ..., housed between these two windows.

we already know several achievements of such chassis having glazing enclosing a blade of air under the above conditions, said chassis breathable, particularly as described in French patent application in the name of the Applicant, filed on January 24, 2002 under the No. 02 00892. However, the provision described in this application preferably applies to a fixed frame, especially of the kind of those planned on the front building or other, particularly in structures say on a curtain wall or the like.

This known solution does not usually apply to a mobile chassis of door or window, in particular of sliding or to strike, whose structure is different and which has sealing means that are not suitable not directly to the establishment of a communication between the inner air space and the outside atmosphere, necessary for breathing desired.

Patent EP 0 953 720 describes a breathable multiple glazing whose exterior glass panel is held by clamping, communication between the air gap and the outside atmosphere requiring a space between the frame and at least part of one side of the panel glass.

The subject of the present invention is a novel double breathable opening structure glazing, sliding type or knock type, which provides an advantageous and effective solution to the disadvantages mentioned above.

For this purpose, the sash frame considered comprising a frame formed by the assembly according to its four sides of joined metal profiles, this frame being mounted in a fixed frame separating the outside atmosphere of an indoor area on the opposite side compared to a glazing carried by this frame and formed of two parallel panes delimiting between them a free space containing a air space, the periphery of at least the first window in contact with the outside atmosphere having its outer edge taken in a wallet in a suitable flexible material, this seal being shaped to include a portion continuous U receiving this edge of the glass and extended by a flat element extending into the free space between the two panes, these with the seal worn by the first being recessed on each side of the chassis in the metal profiles of the frame, is characterized what the U-shaped portion of the seal includes a set of passage holes distributed according to the length of the seal in contact with the lower part of the first pane and in that the metal section arranged under the U-shaped part of the joint recess is pierced with through-holes for establish communication between the air space in the glazing between the two windows and the atmosphere exterior.

According to a complementary characteristic, implemented in a preferred variant but not of the invention, the flat element extending the U-shaped part of the joint receiving the edge of the first window taken in portfolio, is in turn extended by a second part, also in U, in which is taken similarly the edge of the second window, parallel to the first and in look at the inner area.

Preferably also, the two U-shaped parts seal, in which the edges of the panes are taken in the wallet, are identical.

According to another characteristic, the holes of passage in the U-shaped part of the joint receiving the first pane are provided to the right of the connection between this U-shaped part and the flat element which prolongs it in the free space between the two windows.

According to yet another characteristic, the metal section under the U-shaped part of the joint, has a backdrop where the through holes to communicate the blade of air with the outside atmosphere beyond this U-shaped part, this canvas extending over a groove open laterally, arranged in the profile.

Advantageously, the open groove comprises, under the backdrop of the profile, a grid of protection to prevent body penetration solids or various particles in this groove and from there, in the free space between the two windows, up through the through holes of the seal.

According to an alternative embodiment, the second window is applied against the seal by holding beads, carried by the profiles metal frame frame and resting on the outer face of the glass with the interposition of a complementary lip seal.

In one embodiment of the invention, the breathing opening is a sliding leaf, the metal profile that forms the underside of the chassis being provided with at least two bearing, able to move on a rail of guidance, preferably common, carried by the party low fixed frame receiving the opening.

In another embodiment, the opening breathable is of type to hit and is mounted to pivoting on the fixed frame, one of the profiles metal forming a lateral side of the chassis beyond the seal being integral with a hinge hinge.

Advantageously and whatever the mode of envisaged embodiment, the metal sections of the chassis frame include, beyond the seal sealing, externally to the space containing the air gap in the glazing, insulating strips ensuring a thermal break on the part and other of these profiles, outward and inside the chassis.

Other features of a breathable opening made in accordance with the invention will become apparent from the following description of several exemplary embodiments, given by way of non-limiting indication with reference to the accompanying drawings, in which:

• Figure 1 is a perspective view of a frame according to the invention, adapted to a sliding leaf.

• Figure 3 is a sectional view of a frame according to the invention adapted to an opening of the type called striking.
• Figure 4 is an enlarged view of a detail of Figure 3.
• Figures 5, 6 and 7 are sectional views of various variants of the so-called striking chassis according to Figure 3.

In Figure 1, reference numeral 1 denotes a door or window frame for leaf opening sliding, this frame having an outer frame 2 mounted mobile vis-à-vis a fixed frame 3, this frame being constituted by the assembly of profiles 4, arranged on the four sides of opening it and assembled together in the angles of according to provisions which are in themselves conventional and well known in the art.

In the section 4 provided at the bottom of the frame 2, are mounted rollers 5, arranged to be able to move on a common rail 6 to all these wheels, worn by the frame 3 to ensure the movement of the chassis 1 of the opening, this section 4 advantageously comprising side brush seals 7 which rub on the side of the rail 6.

Frame 2 of chassis 1 supports, between four profiles that form the sides of this frame, a glazing unit 8 consisting of two parallel panes, respectively 9 and 10, delimiting between them a free space 11, in which the frame can include accessories 12 of the type store or screen sun visor, whose control means to inside this space 11 do not matter directly to the invention and therefore are not described here.

In the assembly thus produced, the two panes 9 and 10 of the glazing 8 are independent one of the other, so that the space 11 receiving the accessory 12 may not be completely waterproof vis-à-vis the area outside the chassis, this assembly must however be realized so that this space 11 is perfectly isolated opposite the opposite zone, located towards interior, these two areas being schematized on the drawings respectively under the references E and I.

According to the invention, in order to allow that the air space in the space 11 can be put in relation with the zone E situated towards outside and in particular be in equilibrium pressures with the prevailing atmosphere in this area, the frame has a seal 13 which extends according to the length of each of the profiles 4 forming frame 2 following the profile of it, this seal being arranged to ensure a seal only relative to the law of the window 9 in contact with the outer zone E, and a total seal at right of the second window 10 in contact with the area I, this seal allowing in particular to make communicate the space 11 with this zone E.

In particular, the seal 13 has a part continuous U 14 in which the outer edge of the window 9, which extends parallel to the profile 4, is taken in the portfolio, this part 14 is extending by a flat element 15 which delimits the air gap in space 11 between the two panes 9 and 10.

In the example shown, the flat element 15 extends in turn by a continuous second part 16, also in U and in which the edge outside the window 10 is in turn taken in wallet similarly to the corresponding edge of the first window 9.

Advantageously, the seal 13, partly in its two parts 14 and 16 which receive the windows 9 and 10 taken in their portfolio, is vulcanized in its angles to further improve the tightness vis-à-vis the inner zone I.

The set formed by the two windows 9 and 10 and the seal 13 is advantageously embedded in the section 4 of the frame 2, this section including usual in this type of embodiment of the strips transverse 17 of a thermal insulating material, especially in polyamide, realizing a rupture of thermal bridge at the crossing of the chassis 1 between external and internal zones E and I.

According to the invention, the seal 13 cooperating in the manner indicated with the edges of two windows 9 and 10 of the glazing 8, is equipped with according to its length to the right of the section 4 at the bottom of frame 2 in its part which receives the lower edge of the window 9 in contact with the outer zone E, at least one hole of passage 18, preferably several holes successive years, divided according to this length and allow, in cooperation with holes 19 planned opposite or not in the profile, to make communicate the space 11 with this external zone, to allow the air contained in this space to be in communication with the outside atmosphere in this area and to ensure on both sides the window 9 a permanent pressure balance.

According to the invention also, the profile 4 preferably, but not necessarily right of holes 18 and holes 19, in a canvas 20 of the profile under the windows 9 and optionally 10, through orifices 21, allowing the air to be in balance with the outside atmosphere, according to a communication schematized by the arrow 22.

In the example shown in Figure 1, the canvas 20 forms in the profile 4 an open groove 23 which can be normally partially closed by a mesh 24, forming a filter, allowing to prevent particles or solid bodies outside this groove and, holes 21 and holes 18, go back in space 11 between the two panes. The fence 24 is removable and can be set up in front of the groove 23 being introduced in the direction of the arrow 25, in a slider provided for this purpose in this groove.

In the example shown in Figure 1, the two windows 9 and 10 of the glazing 8 are one and the other taken in wallet in parts 14 and 16 of the seal 13. In the variant partially shown in Figure 2, the window 9 is glued against the frame of the opening according to a method of himself well known in the art, which removes part 14 of seal 13 regarding this window 9.

In addition, in this same variant, the seal 13 at the right of the second pane 10 of the pane 8, has a flat edge 26 applied against the surface of this window on the side facing the area internal I, the opposite of space 11, the assembly being sealed by a lip seal or stuff 27, applied on the opposite side of this glazed and maintained by an external pareclose 28 which the end 29 is blocked in a return 30 of section 4, provided for this purpose, this assembly with pareclose having the advantage of a manufacturing simpler and easier maintenance of the accessory 12 housed in the space 11.

Similarly, the different parts of the assembly are arranged so that in the example of the Figure 1, the filter 25 behind the mesh 24, apparent from the outer zone E, while in the case of Figure 2, this filter located in the bottom of the frame behind the fence, either in this case hidden vis-à-vis the outside.

In the embodiment illustrated on the Figures 1 and 2, the frame under consideration is adapted to support of an opening sliding in the frame fixed in which it is mounted.

In Figure 3, a frame is shown of a different type says to hit, adapted to rotate around a joint 31 vis-à-vis his fixed frame 32, this articulation comprising classic way two hinges 33 and 34, respectively immobilized on the frame and opening.

In this Figure 3 and the following figures, has taken identical reference numbers for designate the same organs as in the first example with sliding frame.

In particular, as illustrated in more detail on the Figure 4 with regard to the part of the joint that cooperates with the lower edge of the window 9 (here represented on the right of the figures and no longer left as before), we find the seal 13 comprising its two U-shaped parts, respectively 14 and 16, joined by the flat element 15 to ensure the taken from the outer edge of the windows 9 and 10 of the glazing 8. This provision is also shown in Figure 5 where appear the two transverse bars 17 thermal insulation, the frame comprising a lip seal 35 which rests on the opening in closing position of it, to perfect the tightness on both sides of the glazing 8 between zones I and E.

In Figure 6, the same assembly is associated with a pareclose 28 with a seal 27 applied on the outer edge of the corresponding window. Finally, in Figure 7 is illustrated another form of realization of the pareclose 28, the glazing being taken on the side of Internal Zone I and maintained by a pareclose, preferably in plastic, if any metal, on the side of the external area.

We thus realize a frame structure breathable opening double glazed, design very simple and has the advantage of allowing, at the price of a simple adaptation of the seal sealing, free communication of the blade of air between the two panes with outside and where appropriate inside the chassis, avoiding the disadvantages reveal with a fully enclosed space, do not not allowing in particular to climb into this one an accessory which it is essential to to be able to access.

Of course, it goes without saying that the invention is not limited to the more specially described and represented; she on the contrary, embraces all variants.
