BREATHABLE DOUBLE-WINDOW WINDOW

  The invention relates to the field of windows or double-window / rage windows. These windows have improved performance in terms of thermal and acoustic insulation. Wiles generally comprise an opening opening part, a fixed part asleep for fixing the window to the large work. The opening comprises a frame supporting an internal glazing and an external glazing maintained at a distance from one another by a spacer or spacer. These wind windows are each housed in a rabbet to said frame with or without parecloses, or glues

  on the outside eVou depending on the case, inside the frame of the opening.

  A problem inherent in double-glazed windows is the condensation of water vapor contained in the air gap included in the space formed between the two glazings. This condensation is due to the lowering of the temperature of the air space which causes its saturation in water vapor. Saturation causes condensation of the vapor on the inner surface of the outer glazing, which is usually the coldest surface. This problem is particularly problematic insofar as the interior surfaces of the glazings are not accessible for cleaning. One solution is to make the space between the sealed glazings (for example by forming seals between the glazing and the frame) and dry the air gap using a material absorb moisture. In this way the dew point of the air gap is lowered to never reached temperatures, thus avoiding condensation.

  This solution has some disadvantages, however.

  In particular, the windows being sealed, the air traps in the air space generated by expanding mechanical stresses on the glazing and in the assemblies, especially when the window is subjected to a

284001 1

  sunshine. The thickness of the air space is thus limited by these

mechanical constraints.

  The thickness of the air space being limited, the performances of the

  double-glazing in terms of acoustic insulation are also limited.

  In addition, it is generally not possible to include blinds (blade type or other type) between the two windows because of their

Insufficient spacing.

  Finally, the watertightness achieved being never perfect, this type of

  Double-glazed window has a limited life time.

  To overcome the above-mentioned drawbacks and in particular to limit the phenomena of deformation of the glazings, it is necessary to achieve pressure balancing between the space between the glazings and the outside.

from the window.

  There are windows called "breathable" windows to equilibrate water vapor pressure the air gap with the outside of the glazing. Thus the document WO 00/22273 (published on April 20, 2000) proposes a striking window with opening cover in which an opening has been made in the frame of the opening, opening out into the interlocking zone containing the air gap. and in the peripheral chamber delimited by the frame and the frame, and in which the peripheral chamber communicates

with the outside.

  This device allows a circulation of air between the intervitrage and the outside, via the peripheral chamber, so that the air space is always at the same pressure as the outside air. The temperature of the air space is generally slightly higher than the outside temperature, eliminating the risk of condensation on the face.

interior of the exterior glazing.

  Such a window requires the drilling of the profiles supporting the glazing on their periphery. The profiles are then equipped with pierced specific pieces putting in communication the air space with the outside. These parts have in particular a filter avoiding

  foreign elements inside the air gap.

284001 1

  In such a window, it is often impossible to make a direct path between the air gap and the outside. Or a path

  too crooked can interfere with the proper functioning of the breath.

  In addition, the presence of parts and penetrations can affect the sealing of the window with the interior of the building and generate

problems in case of air conditioning.

  The drilling is delicate to achieve and can be expensive.

  It is therefore an object of the invention to provide a double-window

  breathable glazing does not present the aforementioned drawbacks.

  To this end, the invention proposes a double-glazed window comprising a frame supporting an internal glazing unit and an external glazing unit, the glazings being kept at a distance from one another by spacing means, characterized in that space defined between glazings communicates with the outside by at least one passage at the level of

  from one of the upper corners of the outer glazing.

  Maintaining the passage of air at at least one upper corner of the glazing makes it possible not to weaken the structure of the window. The window of the invention thus guarantees a good resistance to external mechanical stresses on the glazing, and in particular to the action

the wind.

  The invention furthermore guarantees a bilateral exchange of air between the interstage space and the outside of the window, and allows a constant equilibrium of water vapor pressure between the air gap and the air gap.

the outside of the glazing.

  Furthermore, the fact of keeping the air passage at at least one corner of the glazing allows a simple and discreet realization of the ventilation. In one embodiment of the invention, the external glazing has at least one upper angle cut allowing an air passage between the

pan of ['angle cut and frame.

  This particularly simple implementation does not require the drilling of the profiles and makes a direct path between the air gap

  the intervitrage and the outside of the window.

284001 1

  In another embodiment of the invention, the outer glazing has at least one opening in one of its corners

  superiors allowing an air passage.

  This covering also realizes a direct path between the air gap of the intervitrage and the outside of the window. The opening

  can advantageously be achieved by drilling.

  In another implementation of the invention, the spacing means define a rib on either side of which the glazing bears on their periphery, this rib being machined close to one of the upper corners of the external glazing so as to form

  an air passage between the glazing angle and the frame.

  Other features and benefits will come out again from the

  description which follows, which is purely illustrative and not exhaustive and

  to be read with reference to the appended drawings among which: FIG. 1A is a front view of a double glazed window according to an embodiment of the invention; FIG. 1E is a sectional view of a detail of one of the breathing angles of the window of FIG. 1, FIGS. 2A to 2D show representations according to different views (front, bottom, right and perspective respectively) of a first corner angle element intended to be positioned at a breathing corner of the outer glazing, - Figures 3A to 3D wind representations according to different views (respectively front, bottom, right and perspective) of a second piece of room angle to be positioned on the first element, - Figures 4A to 4D wind representations according to different views (respectively front, bottom, right and perspective) of a corner piece member to be positioned at the level of a non-breathable corner of the glazing Figure 5 is a partial perspective view of a window breathable angle in accordance with a second embodiment of the invention; Figure 6A is a partial front view of a window resistive angle; According to a third embodiment of the invention, FIG. 6E is a sectional view of a detail of the breathable angle of the window of FIG. 6A. FIG. 1A shows a view of the outside face of the opening 10 of a << strike >> type window according to an embodiment of the invention. The opening 10 comprises a frame 100 formed of two vertical uprights 102 and 106 connected at their bevel ends by a lower cross member 104 and an upper cross member 108. The uprights and crosspieces 102, 104, 106 and 108 form a wind extruded profile in wood,

in plastic or metal.

  In a manner known per se, an external glazing 14 and an internal glazing 16 (not shown in this view) wind mounted bearing on the frame 100. The edges of the outer glazing 14 wind covered by finishing elements or parecloses 22, 26 and 24, 28 respectively fixed to the uprights 102, 106 and the cross members 104, 108 of the frame 100 by clipping into

  grooves along the profiles.

  These partitions 22, 24, 26 and 28 extend between four corner pieces 31, 33 (represented in dotted lines), 35 and 37 respectively positioned in one of the corners 101, 103, 105, 107 of the frame 100 respectively. and making a junction between the parécloses 22, 24, 26 and 28. These pieces of angles 31, 33, 35, and 37 of general triangular shape also wind up by clipping in the extension of the clipping grooves

  intended for the assembly of partitions 22, 24, 26 and 28.

  The corner pieces 37 and 31 above wind pieces quoted << breathable>, they allow the passage of air between the space defined

  between the windows 14 and 16 and the outside of the opening 10.

  The corner pieces 33 and 35 below have an outer shape similar to the corner pieces 31 and 37. However, these pieces wind pieces quoted << non-breathable >>, they do not allow air exchange between the space 20 defined between the windows 14 and 16 and the outside of

the opening 10.

  In the embodiment shown in Figures 1A and 1E, the upper angles 141 and 147 of the outer glazing 14 have been cut obliquely. Thus, the upper angle 141 positioned in the angle 101 of the frame 100 has been cut in the X direction. The breathable corner piece 31 masks the missing angle of the glazing 14. FIG. 1E is a partial sectional view along the direction DD of the upper breathable angle 101 of the opening 10 in which is the corner piece 31. In this figure, the profile of the upper cross member 108 of the frame 100 forms a rib 13 having two side surfaces 15 and 17 on which the inner and outer glazing 16 and 14 respectively support. This rib 13 constitutes a spacer ensuring a spacing

  gives between the two windows 14 and 16.

  The corner piece 31 comprises a first element 41 or "corner" positioned in the extension of the glazing 14 at its cutting angle 141. It further comprises a second element 51 or "hood" superimposed at the corner 41 and masking from outside the cutting angle 141 of the external glazing 14. The cover 51 is held in the angle 101 of the frame 100 by clipping into the groove 19 formed in the profile of the cross member 108 and

amount 102.

  The two elements 41 and 51 form an air passage (represented by an arrow) ensuring the communication of the space 20 between the

  two windows 14 and 16 with the outside.

  More precisely, FIGS. 2A to 2D show in detail, according to different views, the corner 41 of the breathable corner piece 31 mounted on the cutaway angle 141 of the glazing 14 (represented as a dot). This corner 41 has the general shape of a right triangle. It comprises a bottom wall 402 and edges 404, 406 and 408 extending perpendicularly to the bottom wall 402 on its periphery. The two edges 404 and 406 forming a right angle wind intended to be arranged respectively along the upright 102 and the cross member 108 of the frame 100 of the opening 10 in the angle 101 thereof. The third edge 408 of the wedge 41, opposed to its right angle, is intended to rest on the cutaway 141 of the external glazing 14 of

  so that this corner 41 extends the glazing 14.

  This third edge 408 has a lower lip 410 intended to come into contact with the inner surface 148 of the outer glazing 14 and two upper lugs 412 and 414 positioned on either side of the lower lip 410 and intended to come into contact with the external surface 146 of the external glazing 14. The lower lip 410 and the two upper lugs 412 and 414 thus hold the wedge 41 in the extension of the angle

section 141 of the external glazing 14.

  The bottom wall 402 of the wedge 41 has a triangular opening 416 giving it a general shape in L. Each branch of the L-shaped wall is intended to bear on a rib 13 of the profile.

  amount 102 and the upper rail 108 of the frame 100.

  This wedge 41 makes it possible in particular to support a filter (non

  represents) is positioned on the wall 402 L and covering the triangular opening 416. This filter allows the passage of air through the triangular opening 416 while avoiding ['introduction of particles or parasites

between the two glazings 14 and 16.

  Figures 3A to 3D show in detail in different views, the cover 51 of the breathable corner piece 31. This cover 51 also has a general shape of right triangle. It comprises a substantially planar plate 542 intended to cover the wedge 41 when the latter is positioned in the angle 101 of the frame 100. Each of the two edges 444 and 546 of the plate 542 forming a right angle is extended by a skirt 554, 556 extending perpendicularly to the plate 542. Each skirt 554 and 556 presents along its free edge an excess thickness 564, 566 projecting towards the interior of the cover 51. These skirts 554 and 556 wind are intended to be introduced into the grooves 19 profiles forming the frame 100 for

  clipping the cover 51 in the angle 101 of the frame 100.

  The hood 51 also presents along its edge 548 at its right angle an inclined lip 558 extending the flat surface of the

  plate 542 to the outer surface 146 of the outer glazing 14.

  This lip 558 has an opening 568 allowing the passage of air between the plate 542 of the cover 51 and the wedge filter 41 positioned under the cover 51 as represented by the arrow in Figure 1 E. This cover has opened >> 51 protects and covers the corner 41 supporting the filter. In particular, its inclined lip 558 entrains the runoff of rainwater along its edge and thus prevents the introduction of water on the corner 41 and

in the filter it contains.

  4A to 4D show in detail according to different views, the cover 45 of the non-breathable corner piece 33 mounted in the lower angle 103 of the frame 100. This cover 45 has a general shape similar to the cover 51 of FIGS. 3A. a 3D, except that it does not include an opening in its inclined lip 558. This lip 558 is full and is in contact on

  all its free edge with the external surface 146 of the external glazing 14.

  This cover says mouth >> 45 is mounted in the same way as the cover 51 by clipping in ['lower angle 103 of the frame 100. At this point, the angle 143 of the external glazing 14 is not cut and the piece d angle 33

there is no breathable corner.

  In addition to the fact that the four corner pieces 32, 34, 36 and 38 confer a symmetry to the opening, these corner pieces advantageously constitute safety parts ensuring the maintenance of the outer glazing 14 on the frame 100 in case, for example, detachment of this frame 100 glazing

of the opening 10.

  Nevertheless, it will be understood that the lower corner pieces 34 and

  32 are not necessary for the realization of the breathing.

  Moreover, it is possible to choose to perform the breathing only in one of the two upper angles 101 or 107 of the frame 100, in which case the

  assembly requires only one breathable corner piece 31 or 37.

  According to another embodiment of the invention represented in FIG. 5, the breathing is not performed by cutting the angle of the glazing.

  but per per, cant an opening 142 in the corner of this glazing.

  In this embodiment, a wedge 42 similar to the corner 41 of Figure 2A but having a slot 409 housed between its lower lip 410 and its two lugs 412 and 414 superiors is positioned on the angle 141 pierced glazing. The angle 141 of the glazing 14 is inserted into the slot 409 of the wedge 42 so that the triangular opening 416 of the L-shaped wall is superimposed on the pierced opening 142 of the glazing 14.

  through the triangular opening 416 and the pierced opening 142.

  The wedge 42 may advantageously support a filter.

  In a variant of this embodiment, the window is pierced and no corner is used. In this case the filter can be mounted directly

  on the pierced opening 142 of the glazing 14.

  An open hood similar to the hood 51 of FIGS. 3A to 3D covers

  and protects the breathable corner of the glazing.

  According to another embodiment of the invention represented in FIGS. 6A and 6E, the spacer 13 formed in the profiles of the upper cross member 108 and the amount 102 of the opening 10 is machined in the corner 101 of the frame 100. machining may for example consist in the realization in the thickness of the spacer 13 a groove 144 for milling the spacer 13 at the junction between the upright 102 and the upper rail 108. The milling is performed in the direction represented by the arrow F from the surface 17 of rib 13 in contact with the inner surface 148 of the

external glazing 14.

  FIG. 6E is a partial view in section along the direction DD of the upper breathable angle 101 of the opening 10. As illustrated in this figure, this machining consists in providing a passage of air around the corner 141 of the glazing. 14. This passage allows the flow of air (represented by an arrow) between the space 20 defined between the windows 14 and 16 and the outside. In this implementation, it also covers the breathable angle 141 of a protective cover similar to the cover 51 of Figures 3A to 3D. It is also possible to cover this angle 141 with a corner piece

  less "covering" than in the implementations described previously.

  It is advantageous to position on this breathing angle a hood in

  L-shaped extending the parecloses 22 and 28.

  The protective cover can also support a filter.
