Description

The present invention relates to a double sash frame

  glazing, provided with means allowing the existing air space, trapped between the two independent parallel windows which form this glazing, to be put into permanent relationship and in equilibrium with the external atmosphere, in particular to avoid phenomena condensation or other on the faces of the windows opposite, these means being also arranged, because these two panes are not connected directly to one another to form a unitary unit sealed and sealed o the blade of air would be totally confined, so as to facilitate the assembly, maintenance and possible repair 15 various accessories, the kind of blind, sun screen, internal curtain etc ..., housed between these two panes. Several embodiments of such frames having a glazing unit enclosing an air knife in the above-mentioned conditions, said chassis being breathable, are already known, in particular as described in the French patent application in the name of the Applicant, filed on January 24, 2002 under the No. 02 00892. However, the arrangement described in this application, as generally in the state of the art, preferably applies to a fixed frame, in particular of the type of those provided on the facade of a building or the like, in particular in structures

say on a curtain wall or the like.

  On the other hand, the known solutions do not usually apply to a mobile door or window frame, in particular of a sliding or striking leaf, whose structure is different and which comprises sealing means which do not lend themselves directly the establishment of a communication between the inner air space and the external atmosphere, necessary for the desired breathing. The present invention relates to a new breathable opening frame structure with double glazing, of the sliding or knocking type, which provides an advantageous and effective solution to this problem.

particular problem.

  For this purpose, the sash frame considered having a frame formed by the assembly along its four sides of contiguous metal profiles, this frame being mounted in a fixed frame separating the external atmosphere from an inner zone situated on the opposite side relative to a glazing carried by this frame and formed of two parallel panes 15 delimiting between them a free space containing an air space, the periphery of at least the first window in contact with the outside atmosphere having its outer edge taken in the wallet in a seal made of a suitable flexible material, this seal being shaped to comprise a continuous U-shaped portion receiving this edge of the pane and extended by a flat element extending in the free space between the two panes these, with the gasket carried by the first being embedded in each of the sides of the frame in the metal profiles of the frame, are characterized in that the U-shaped part of the seal comprises a set of passage holes distributed along the length of the seal in contact with the lower part of the first pane and in that the metal section

  disposed under the U-shaped portion of the gasket which is embedded in it is pierced with through holes to establish a communication between the air gap in the glazing between the two panes and the outside atmosphere.

  According to a complementary feature, implemented in a preferred but non-exclusive variant of the invention, the flat element extending the U-shaped part of the seal receiving the edge of the first window taken in the wallet, is in turn extended by a second part, also in U, in which is taken similarly the edge of the second pane, parallel to the first and in

look at the inner area.

  Also preferably, the two U-shaped portions of the gasket, in which the edges of the panes are

  taken in the wallet, are identical.

  According to another characteristic, the passage holes formed in the U-shaped portion of the gasket 15 receiving the first pane are provided in line with the connection between this U-shaped portion and the flat element which extends it in the free space between the two. windows. According to yet another feature, the metal section under the U-shaped portion of the joint comprises a backdrop where the through holes are drilled to communicate the air gap with the outside atmosphere beyond this U-shaped portion. this fabric extending over a laterally open groove formed in the profile. Advantageously, the open groove comprises, under the backdrop of the profile, a protective grid to prevent the penetration of solid bodies or various particles in this groove and, from there, in the free space between the two panes, by ascent through the through holes

of the seal.

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

complementary lip seal.

  In one embodiment of the invention, the breathable opening is a sliding leaf, the

  metal section which forms the underside of the frame being provided with at least two rolling members, adapted to move on a guide rail, preferably common, carried by the lower part of the fixed frame receiving the opening.

  In another embodiment, the breathable opening is of the striking type and is pivotally mounted on the fixed frame, one of the metal sections forming a lateral side of the frame beyond the seal being integral with a frame.

hinge hinge.

  Advantageously and whatever the embodiment envisaged, the metal profiles of the frame of the chassis comprise, beyond the seal 20, externally to the space containing the air gap in the glazing, insulating strips ensuring a break of thermal bridge on either side of these profiles, outward and

inside the chassis.

  Other features of a chassis

  According to the invention, breathable according to 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. 2 is a partial sectional view of the lower part of a sliding leaf of the general type illustrated in FIG. 1, but in which, as a variant, one of the panes of the glazing unit is fixed to the frame by gluing, the other window being

  maintained by a conventional pareclose device.

  - Figure 3 is a sectional view of a frame 5 according to the invention adapted to an opening of the type

  - Figure 4 is an enlarged view

a detail of Figure 3.

  5, 6 and 7 are sectional views of various variants of the so-called striking chassis according to FIGS.

Figure 3.

  In Figure 1, the reference 1 designates a door or window frame for sliding leaf, this frame having an outer frame 15 2 mounted to be movable vis-à-vis a fixed frame 3, this frame being constituted by the assembly of metal sections 4, arranged along the four sides of

  opening and assembled together in the corners thereof in accordance with provisions which are in themselves classic 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 rail 6 common to all these wheels, carried by the frame 3 25 to ensure the movement of the 1 of the opening frame, this profile 4 advantageously comprising side brush seals 7 which rub on the

side of the rail 6.

  The frame 2 of the frame 1 supports, between the four sections which form the sides of this frame, a glazing 8 consisting of two parallel panes, respectively 9 and 10, delimiting between them a free space 11, in which the frame may comprise accessories 12 of the kind blind or screen 35 sun visor, whose control means within this space 11 do not directly matter 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 of each other, so that the space accommodating the accessory 12 may not be totally watertight with respect to the zone located towards the outside of the frame, this assembly must instead be made such that this space 11 is perfectly isolated vis-a-vis the opposite zone, located inward, these two areas being schematized in the drawings respectively in the references E and I. In accordance with the invention, in order to allow the air gap in the space 11 to be connected to the outwardly facing zone E, and in particular to be in equilibrium with pressure with the atmosphere that prevails in this area, the frame has a seal 13 which extends along the length of each of the profiles 4 forming the frame 2 following the profile thereof, this seal being arranged to provide a sealing only relat ive to the right of the window 9 in contact with the outer zone E, and a total seal to the right of the second pane 10 in contact with the inner zone I, this seal allowing in particular to make the space 11 communicate with this zone E In particular, the seal 13 comprises a U-shaped continuous portion 14 in which the outer edge of the pane 9, which extends parallel to the profile 4, is taken up in the wallet, this portion 14 being extended 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 is in turn extended by a second continuous portion 16, also U-shaped and in which the outer edge of the pane 10 is in turn taken in the wallet similarly to the corresponding edge

of the first window 9.

  Advantageously, the seal 13, in part in its two parts 14 and 16 which receive the windows 9 and 10 taken in portfolio in them, is vulcanized in its corners to further improve the seal vis-à-vis the inner area I. The assembly formed by the two panes 9 and 10 and the gasket 13 is advantageously embedded in the section 4 of the frame 2, this section conventionally comprising, in this type of embodiment, transverse bars 17 made of a thermal insulating material, in particular polyamide, achieving a thermal break in the crossing of the frame 1 between the outer and inner zones E and I. According to the invention, the seal 13 cooperating in the indicated manner with the edges of the two panes 9 and 10 8 of the glazing, is arranged so as to comprise, along its length to the right of the section 4 to the lower part of the frame 2 in its portion which receives the lower edge of the pane 9 in contact with the outer zone E, at the m oins a hole of passage 18, preferably several successive holes, distributed along this length and which, in cooperation with holes 19 provided opposite or not in the profile, to 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 of

  the window 9 a permanent pressure balance.

  According to the invention also, the profile 4 35 comprises, preferably but not necessarily to the right of the holes 18 and holes 19, in a fabric of the profile provided under the panes 9 and possibly 10, through orifices 21, allowing the air in equilibrium with the outside atmosphere, according to a communication schematized by the arrow 22. In the example illustrated in Figure 1, the fabric 20 forms in the section 4 an open groove 23 which can be normally closed partially by a grid 24, forming a filter, for preventing particles or external solid bodies from passing through this groove and, through the orifices 21 and the holes 18, do not rise in the space 11 between the two panes. The grating 24 is removable and can be put in place in front of the groove 23 by being introduced in the direction of the arrow 25, in a slide provided for this purpose

in this groove.

  In the example shown in FIG. 1, the two panes 9 and 10 of the glazing 8 are both held in the parts 14 and 16 of the gasket 13. In the variant partially shown in FIG. 2 , the window 9 is glued against the frame of the sash according to a method itself well known in the art, which eliminates the part 14 of the seal 13 concerning this

window 9.

  Furthermore, in this same variant, the seal 13 at the right of the second pane 10 of the pane 8 comprises a flat rim 26 applied against the surface of this pane on the side directed towards the inner zone I, opposite the space 11, the assembly being sealed by a lip seal 27, applied on the opposite face of this window and held by an external pareclose 28 whose end 29 is locked in a return 30 of the section 4, provided for this purpose, this assembly with pareclose having the advantage of simpler manufacturing and easier maintenance of

  the accessory 12 housed in the space 11.

  Similarly, the different parts of the assembly 5 are arranged so that in the example of the

  Figure 1, the filter 25 behind the grill 24, is apparent from the outer zone E, while in the case of Figure 2, this filter located at the bottom of the frame behind the grill, is 10 in this case hidden vis- to the outside.

  In the embodiment illustrated in Figures 1 and 2, the frame considered is adapted to the support of an opening which slides in the frame

fixed in which it is mounted.

  In Figure 3, there is shown a frame of a different type said striking, adapted to pivot about a hinge 31 vis-à-vis its fixed frame 32, this hinge conventionally comprising two hinges 33 and 34 , Respectively immobilized on the frame and the opening. In this Figure 3 and the following figures,

  has taken identical reference numerals to designate the same members as in the first example sliding frame.

  In particular, as illustrated in more detail in FIG. 4 with regard to the part of the seal which cooperates with the lower edge of the pane 9 (here represented on the right of the figures and no longer on the left as previously), the seal is found again. 13 comprising its two U-shaped portions, respectively 14 and 16, joined by the flat member 15 to ensure the portfolio of the outer edges of the panes 9 and 10 of the glazing 8. This arrangement is also shown in Figure 5 o appear the two transverse bars 17 thermal insulation, the frame comprising a lip seal 35 which bears on the opening in the closed position thereof, to complete the seal 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 to the outer edge of the corresponding pane. Finally, in FIG. 7 is illustrated another embodiment of the beaker 28, the glazing being taken in the wallet on the side of the inner zone I and held in place by a bead, preferably made of plastic, if appropriate metal, of the side of the

external area.

  Thus, a breathable opening frame structure with double glazing, of very simple design and which has the advantage of allowing, at the cost of a simple adaptation of the seal, the free communication of the blade 20. air between the two panes with the outside and where appropriate the inside of the frame, avoiding the disadvantages that are revealed with a fully enclosed space, not allowing in particular to mount in it25 an accessory to which it is essential of

to be able to access.

  Of course, it goes without saying that the invention

  is not limited to the embodiments more specifically described and shown; on the contrary, it embraces all the variants.
