Description

ELEMENT FOR MEDIUM PLAN DOOR, WINDOW OR PANEL

  OF DEFORMABLE SEALING AND ITS MANUFACTURING PROCEED

  The present invention relates to an element for a door, window or flat facade panel, more particularly an element for double

  glazing, and its manufacturing process.

  We already know double glazing consisting of two transparent parallel glass panels, separated by a spacer containing a desiccant, defining a closed enclosure

  containing a colorless gas which is usually air.

  We also know double glazing inside which we place a folding accordion blind. In winter, these blinds are lowered at night to avoid heat loss and folded down during the day to allow the use of solar heat. Conversely, in summer, we lower the blind during the day, and fold it up at night. To allow the awning to be housed between the two glass panels, the distance between these panels must be large. In addition, the larger the air gap between the two panels, the better the properties.

  thermal insulation of double glazing.

  However, increasing the thickness of the air gap poses problems. In fact, when the temperature varies inside the enclosure, the pressure and the volume of the air gap vary, causing deformations and constraints of the double glazing. However, the larger the initial volume of this air space, the greater the variations in volume

  depending on temperature variations.

  Thus, from a certain thickness of the air space, the adhesion and the effectiveness of the seals are

  danger, before arriving at the risk of implosion or explosion.

  As a result, moisture can penetrate inside the enclosure and cause undesirable effects (halo of mist, corrosion, etc.). To overcome these drawbacks, multiple solutions have been proposed. In a first variant, described in French patent 83.14724, there is provided a variable volume formed of the spacer and a flexible membrane. In a second variant, such as that described in German patent 2031576, provision has been made to interpose means for varying the thickness of the air gap between the spacer and the interior panel. However, none of the known solutions is satisfactory. Indeed, in the first variant, the volume variations are not enough and in the second variant, the sealing and the maintenance of the panel are not ensured. In addition, these solutions are sophisticated, expensive and do not offer sufficient reliability, such as that required in the construction of buildings. Consequently, the invention aims to overcome these drawbacks and to provide an economic solution, reliable in the long term, allowing the simple production of double glazing with a large thickness of air layer completely waterproof. , steam

water, air and other gases.

  To this end, the invention provides an element for a door, window or flat front panel consisting essentially of at least two parallel flat panels, facing each other, spaced a distance d from one of the other by a peripheral profile interposed in a spacer, between the two panels, of peripheral association means of the two panels with one another and / or to the profile, the enclosure formed of the two panels, of the profile and of said association means containing a gas and being hermetically sealed by peripheral means of sealing against water, steam, air and at least said gas, characterized in that the sealing means are interposed with a part between the inner panel and the profile and, secondly, between the outer panel and the profile and in that these sealing means are elastically deformable transversely so as to allow relative movements of the panels, one relative to the other, in relation to the 'profile and in the a transverse direction, as a function of the temperature and / or pressure variations in the hermetic enclosure, without however causing deterioration of these sealing means; the sealing means are deformed transversely beforehand, by compression so as to be permanently compressed against the panels, even when the latter are separated as far as possible; the sealing means consist of a generally elongated joint, consisting of a central core of transversely deformable material, coated with a layer of material impermeable to water, steam, air , and at least the gas contained in the airtight enclosure; the peripheral association means are association means of each of the panels with the profile, elastically deformable transversely, consisting of two silicone seals interposed respectively between each of the panels and the profile, preferably superimposed on the sealing means at the periphery external of the element. Preferably, the outer layer of the sealing means is made of polyisobutylene (or

  butyl) and the association means are made of silicone.

  An element according to the invention advantageously comprises means of variable thermal insulation inside the enclosure such as a blind, and an internal glazing bead rigidly associated with the profile. The invention also relates to a method of manufacturing such an element, in which the transverse deformations are

  compression sealing means.

  Thus, an element for a door, window or facade panel according to the invention can withstand large variations in temperature and pressure, while being of considerable width and having

  excellent thermal and acoustic insulation properties.

  In fact, the two panels can move relative to the profile to be compensated by a variation in volume, variations in internal pressure due to variations in temperature or movements of the insulation means, or the like. The sealing means being deformed beforehand by compression, in particular of the order of 33% of their initial thickness, are permanently compressed between the panels and the profile, never work in transverse traction and therefore cannot be detached from the panels. and the profile. Consequently, an element according to the invention remains perfectly sealed even under extreme operating conditions (high or low temperatures, deployment or folding back at high speed of the insulation means, etc.). Finally, the application of the deformable sealing means to an element according to the invention, in addition to the technical advantages mentioned above, makes it possible to obtain a price.

  very low cost compared to known solutions.

  Other characteristics and advantages of the invention

  will appear on reading the description of one of its modes of

  preferred embodiments, made with reference to the appended figures in which: - Figure 1 is a vertical section view of an element according to the invention, the insulation means being fully deployed, - Figure 2 is a horizontal section view of an element according to the invention, - Figure 3 is a half-view in vertical section of an element according to the invention, the insulation means being fully folded back, - Figure 4 is an enlarged cross-sectional view of a profile and an internal glazing bead of an element according to the invention, - Figure 5 is a plan view of an element according

  the invention, the isolation means being fully deployed.

  An element 1 for door, window or plane front panel is made up in a known manner of two panels 2, 3 parallel planes facing each other, spaced a distance from each other. The panel 2 is turned towards the inside 4 of the building, and the panel 3 is turned towards the outside 5 of the building, the element 1 separating by isolating them from each other the interior space 4 of the exterior space 5 of the building. In the following, the words "interior and 'exterior' refer to these interior 4 and exterior 5 spaces. The building, not shown, does not matter within the scope of the invention and can be of any type, for example example a building, a house, a ship, a vehicle, or other. The main function of such an element 1 is therefore to thermally and acoustically insulate the two spaces

  interior 4 and exterior 5 of each other as best as possible.

  Generally, the panels 2 and 3 are made of glass to let the light through. The distance d separating the two inner 2 and outer 3 panels from each other and the distance between the inner face 6 of the inner panel 2 and the inner face 7 of the outer panel 3; when the internal space 8 between the two panels is under the same pressure and temperature conditions as the external space 9, generally corresponding to the normal pressure and temperature conditions (20 ° C., Pa). The two panels 2, 3 are spaced from each other by the distance d by a peripheral profile 10 inserted in a spacer

between the two panels 2, 3.

  Preferably, the two panels 2, 3 are of generally rectangular shape, and the profile 10 defines a rectangular cover interposed between the two panels 2, 3 in the vicinity of their

  periphery, substantially parallel to each of their sides.

  Element 1 is generally rectangular (FIG. 5) and has four edges 11, 12, 13, 14, an internal face 15 which is the external face of the internal panel 2 and an external face 16 which is the external face of the external panel 3 For simplicity, it will be assumed that the element 1 is vertical, with its edges 11, 12 the longest vertical, and its edges 13, 14 the shortest horizontal, as shown in FIG. 5. This is generally the case in practice , although other arrangements are possible. The element 1 comprises means 17 for peripheral association of the two panels 2, 3 with one another and / or with the profile 10. The enclosure 8 formed by the two panels 2, 3, of the profile 10 and means 17 for association contains a gas, preferably air and is closed hermetically by peripheral means 18 for sealing against water, steam, air and at least at least

says gas.

  According to the invention, sealing means 18 are interposed on the one hand between the interior panel 2 and the profile 10, and on the other hand between the exterior panel 3 and the profile 10, and these sealing means 18 are elastically deformable transversely so as to allow deformations of the panels 2, 3 and / or relative displacements of the panels 2, 3 relative to one another, and relative to the profile 10 in the transverse direction, that is to say that is to say perpendicular to the median plane P parallel to the panels 2, 3, as a function of the variations in temperature and / or pressure in the hermetic enclosure 8, without however causing deterioration of these sealing means 18. In combination with the previous characteristic, the peripheral association means 17 are elastically deformable transversely to allow deformations and displacements in the transverse direction of the panels 2, 3, one with respect to

  the other and relative to the profile 10.

  Thus, when the pressure P1 in the enclosure 8 tends to vary, the deformations and displacements of the panels 2, 3 in the transverse direction compensate for this variation in pressure by a variation in the volume of the enclosure 8, avoiding the deterioration of

  element 1, and more particularly sealing means 18.

  Preferably, the peripheral association means 17 are association means 17 for each of the panels 2, 3 to the profile, and are interposed on the one hand between the interior panel 2 and the profile 10 and on the other hand between the exterior panel 3 and the

profile 10.

  These means 17 of association, and preferably also the sealing means 18 are non-deformable or not deformable in any direction parallel to the median plane P parallel to the panels 2, 3. Thus, excessive unwanted movements of the panels 2 are avoided, 3 with respect to each other or with respect to the profile 10 in the directions parallel to the plane P. The means 17 for association, and possibly also the sealing means 18 are rigid or almost rigid parallel to the plane P .- One of the consequences of this rigidity is that the element 1 according to the invention does not tend to sag over time. Indeed, in an element 1 according to the invention, the outer panel 3 has a slightly larger area than the inner panel 2, and the element? 1 according to the invention is rigidly associated with the building or the size of the door or window by the external panel 3, the internal panel 2 being left free. Thus, in practice, the outer panel 3 is fixed, and the rest of the element 1 (profile 10, inner panel 2, ...) is mounted floating relative to this outer panel 3. This is why it is advantageous for the peripheral association means 17 to be rigid parallel to the plane P. When the pressure and / or temperature variations in the enclosure 8 cause an increase in volume (increase in temperature, deployment of the isolation means. .), the panels 2, 3 deform or bend, and generally the center of these panels moves more than the edges which are relatively held by the means 17 of association. In current applications of an element 8 according to the invention, it is more common to observe such increases in volume compared to normal conditions than decreases. This is why the sealing means 18 are deformed transversely beforehand by transverse compression, in particular crushed between 20 and 50% of their thickness, when the element 1 is at rest, the pressure and the temperature in the enclosure 8 being normal. and homogeneous, the means 17 of association maintaining these deformed and compressed sealing means 18 between each of the two panels 2, 3 and the profile 10, so that the sealing means 18 are permanently compressed against the panels 2 , 3 and the profile 10, even when the panels 2, 3 deviate as much as possible from the profile 10, in particular

  under the effect of an increase in temperature in enclosure 8.

  Thus, the sealing means 18 are never stressed in transverse traction and are always compressed between each of the

panels 2-, 3 and profile 10.

  On the other hand, the association means 17 are not deformed beforehand and are stressed in transverse traction even when the element 1 is at rest, maintaining the sealing means 18 deformed and compressed between each of the panels 2, 3 and the profile. 10. It is thus preferable that the sealing means 18 are more flexible in the transverse direction.

that means 17 of association.

  The sealing means 18 advantageously consist of a seal of generally elongated shape, consisting of a central core 20 of transversely deformable and elastic material, in particular of synthetic foam such as PVC, this core 20 being coated a layer 21 of material impermeable to water, water vapor, air and at least the gas contained in the hermetic enclosure 8, in particular polyisobutylene. Thus, the sealing means 18 consist on the one hand of an internal seal 22 applied to the internal face 6 of the internal panel 2, substantially parallel to its four edges 24, and on the contact wall 25 of the profile 10 opposite, and on the other hand, a seal 23 applied to the internal face 7 of the external panel 3, substantially parallel to its four edges 26,

  and on the contact wall 27 of the profile 10 opposite.

  The association means 17 are preferably superimposed on the sealing means 18, and surround these sealing means 18, separating them from the external space 9, as shown in the figures. Thus, the means 17 of association are in contact with the external space 9, and the sealing means 18 are in contact

internal space 8.

  As a variant, the sealing means 18 are superimposed on the association means 17, and surround these association means 17

  by separating them from the external space 9.

  According to another variant, the sealing means 18 are superimposed on a first part of the association means 17, and a second part of the association means 17 is superimposed on the sealing means 18 which are then surrounded by the means 17 of association on both sides. In this case, only the association means 17 are in contact with the internal 8 and external 9 spaces, the sealing means 18 being separated by the association means 17. The means 17 for association may be at a certain distance from the sealing means 18, but preferably the means 17

  association are in contact with the sealing means 18.

  In the preferred embodiment, the means 17 for association consist of an inner peripheral seal 28 superimposed in contact with the inner seal 22 of the sealing means 18, and an outer seal 29 peripheral superimposed in contact with the outer seal 23 sealing means 18. The means 17 for association are advantageously made of silicone. Thus an element 1 according to the invention essentially comprises four peripheral seals: An interior seal 22 of PVC foam coated with butyl and an interior seal 28 of silicone association interposed between the interior panel 2 and the profile 10, and ' an outer seal 23 of PVC foam coated with butyl and an outer seal 29 of silicone association inserted between the panel

outside 3 and profile 10.
