Abstract
Description
L'invention se rapporte à un dispositif d'isolation de baies vitrées. The invention relates to a device for insulating bay windows.
La nécessité de faire des économies d'énergie a favorisé le développement des dispositifs permettant de doubler les vitrages traditionnels par des vitrages additionnels avec interposition d'une lame isolante d'air. De tels dispositifs ont été dénommés "survitrage". Ils sont en principe constitués par un châssis porteur de la seconde vitre ou glace, monté fixe ou articulé sur celui de la baie. Ces dispositifs réduisent les dépenses de chauffage en diminuant sensiblement de moitié les fuites de calories à travers les parties vitrées et en supprimant l'effet de paroi froide. Ils permettent aussi un affaiblissement acoustique traversant, pouvant aller jusqu'à 30 dBA pour une fenêtre rendue étanche à l'air. The need to save energy has favored the development of devices making it possible to double traditional glazing with additional glazing with the interposition of an air insulating layer. Such devices have been referred to as "glazing". They are in principle constituted by a frame carrying the second window or glass, mounted fixed or articulated on that of the bay. These devices reduce heating costs by substantially halving the heat leakage through the glass parts and by eliminating the cold wall effect. They also allow through sound reduction, up to 30 dBA for a window made airtight.
Evidemment, l'amélioration de l'isolation thermique et phonique est réversible (intérieur vers l'extérieur ou extérieur vers l'intérieur). Obviously, the improvement in thermal and sound insulation is reversible (interior to the exterior or exterior to the interior).
Dans ce dernier cas, il est bien connu d'utiliser des stores placés derrière le vitrage, stores ayant pour objet d'arrêter on atténuer le passage des rayons lumineux du soleil. In the latter case, it is well known to use blinds placed behind the glazing, blinds having the object of stopping or attenuating the passage of the light rays of the sun.
On connait des stores fait d'une feuille plastique réfléchissante par exemple une nappe sandwich de deux films de polyester transparent revêtus d'une trame d'aluminium déposée par vaporisation sous vide, cette nappe pouvant être calendrée à chaud ou non. We know blinds made of a reflective plastic sheet for example a sandwich sheet of two transparent polyester films coated with an aluminum frame deposited by vacuum spraying, this sheet can be calendared hot or not.
L'écran constitué par ce type de store, basé sur le principe des "miroirs indiscrets" chers aux Vénitiens du
XVIIe siècle, permet une bonne vision vers l'extérieur, tout en agissant comme réflecteur des rayons calorifiques par diffraction de ces rayons (théorie de Ernst AUBE)
Il faut néanmoins observer que si ces stores empêchent la propagation de l'onde calorifique en direction de l'intérieur de la pièce, ils ne peuvent s'opposer à l'échauffement de la lame d'air située entre eux et le vitrage, et qui selon les règles de la thermodynamique diffuse par les cotés restes libres.The screen constituted by this type of blind, based on the principle of "prying mirrors" dear to the Venetians of
17th century, allows a good vision towards the outside, while acting as a reflector of the heat rays by diffraction of these rays (theory of Ernst AUBE)
However, it should be noted that if these blinds prevent the propagation of the heat wave towards the interior of the room, they cannot prevent the heating of the air space between them and the glazing, and which according to the rules of thermodynamics diffuses by the sides free remainders.
Pour obvier à cet inconvénient, on a proposé de disposer le store réfléchissant à l'intérieur d'un cadre marginal. To overcome this drawback, it has been proposed to arrange the reflective blind inside a marginal frame.
Cette disposition a amélioré le rendement sans toutefois réussir à éviter les fuites en raison de l'impossibilité de réaliser un boitier réellement étanche, uniquement constitué par un cadre. This arrangement improved the yield without, however, succeeding in avoiding leaks due to the impossibility of producing a genuinely watertight case, consisting solely of a frame.
La présente invention se propose de résoudre ce problème en plaçant l'écran réfléchissant dans l'espace compris entre la glace extérieur traditionnelle et celle du survitrage, ledit espace constituant une enceinte étanche. The present invention proposes to solve this problem by placing the reflecting screen in the space between the traditional exterior glass and that of the glazing, said space constituting a sealed enclosure.
D'autres particularités et avantages apparaitront lors de la lecture de la description et des revendications qui suivent, faites en regard du dessin annexé représentant en coupe partielle du dispositif d'isolation conforme à l'invention. Other particularities and advantages will appear on reading the description and the claims which follow, made with reference to the appended drawing representing in partial section of the insulation device according to the invention.
Comme on le voit sur cette figure, la glace extérieure VE est fixée dans la feuillure du dormant D où elle est immobilisée par la parclose P. As can be seen in this figure, the external window VE is fixed in the rebate of the frame D where it is immobilized by the glazing bead P.
Sur la face intérieure de ce dormant est fixé le châssis du survitrage SV, ici un châssis ouvrant. On the inner face of this frame is fixed the frame of the SV glazing, here an opening frame.
Dans ce cas, la fixation consiste en des charnières
CH dont un des charnons est vissé sur le dormant et l'autre solidaire du châssis SV.In this case, the fixing consists of hinges
CH of which one of the knuckles is screwed on the frame and the other integral with the SV chassis.
D'une manière connue, ce dernier comporte une rainure SV1 destinée à recevoir un joint ET assurant l'étanchéité entre le châssis et le dormant, et une rainure SV3 recevant la glace VI du survitrage avec interposition d'un joint-clips CL. In a known manner, the latter comprises a groove SV1 intended to receive a seal ET ensuring the seal between the chassis and the frame, and a groove SV3 receiving the glass VI of the glazing with the interposition of a joint-clips CL.
En raison de la présence de ces joints ET et CL, l'enceinte comprise entre les glaces VE et VI est close d'une manière étanche. Due to the presence of these ET and CL seals, the enclosure between the VE and VI windows is sealed.
Dans la partie supérieure de cette enceinte, on place le boîtier traditionnel du store ST mobile, enfermant le tambour manoeuvrable de l'extérieur, le store ST étant guidé latéralement dans la rainure SV2 du châssis du survitrage SV. Ce store se déplace donc dans l'enceinte close en la divisant en deux zones : une zone antérieure ECl et une zone postérieure EC2. In the upper part of this enclosure, the traditional casing of the movable ST blind is placed, enclosing the maneuverable drum from the outside, the blind ST being guided laterally in the groove SV2 of the frame of the SV glazing. This blind therefore moves within the closed enclosure by dividing it into two zones: an anterior zone EC1 and a posterior zone EC2.
Ainsi, sans avoir besoin d'utiliser un châssis spécial pour le store, châssis dont l'installation est onéreuse en main-d'oeuvre et en matière, et dont la saillie venant s'ajouter à celle du survitrage prohiberait l'emploi du store placé à l'arrière du survitrage. Thus, without the need to use a special frame for the blind, a frame whose installation is costly in terms of labor and material, and the projection of which, being added to that of the over-glazing, would prohibit the use of the blind. placed at the rear of the glazing.
Le Demandeur a constaté que les résultats découlant de l'application de l'invention sont bien meilleurs que ceux inhérents à l'emploi du store à l'extérieur du survitrage. The Applicant has found that the results resulting from the application of the invention are much better than those inherent in the use of the blind outside of the glazing.
En effet, le store en position d'utilisation partageant la lame d'air placée entre vitrage et survitrage en deux zones EC1 et EC2, l'air de celles-ci va se trouver à des températures différentes, la zone EC2 la moins chaude servant de tampon, il s'en suit une amélioration notable du coefficient K d'isolation thermique. Indeed, the blind in the position of use sharing the air space placed between glazing and glazing in two zones EC1 and EC2, the air of these will be at different temperatures, the zone EC2 the warmest serving of buffer, there follows a notable improvement in the coefficient K of thermal insulation.
Par ailleurs, on a observé que l'utilisation des survitrages étanches avait considérablement diminué les phénomènes de condensation. COURTIER, le siècle dernier, a montré que les impuretés et poussières en suspension modifiaient le point de rosée, en agissant comme noyaux de condensation. En supprimant ces poussières on a rendu plus difficile les condensations. Il ne faut pas oublier > néan- moins, que celles-ci sont fonction des températures critiques. Le Demandeur a observé d'une manière surprenante, sans qu'il puisse en donner une explication, que la présence du store dans l'enceinte close inter-vitrage, réduisait considérablement le risque de condensation
On peut tout au plus supposer que le store forme un écran s'opposant à la migration de l'air en direction de la glace froide.Furthermore, it was observed that the use of sealed glazing had considerably reduced the phenomena of condensation. COURTIER, the last century, has shown that suspended impurities and dust modify the dew point, acting as nuclei of condensation. By removing this dust, condensations have been made more difficult. It should not be forgotten, however, that these are a function of critical temperatures. The Applicant has observed, surprisingly, without being able to give an explanation, that the presence of the blind in the closed inter-glazing enclosure considerably reduces the risk of condensation.
At most, we can assume that the blind forms a screen opposing the migration of air towards the cold ice.
Enfin, les stores réfléchissants en polyester sont relativement fragiles, ils se salissent facilement, ils se dégradent vite, et leur pouvoir réfléchissant s'en trouve altéré. Finally, polyester reflective blinds are relatively fragile, they get dirty easily, they degrade quickly, and their reflecting power is affected.
Dans leur emploi actuel, ils ne sont nullement pratiques, alors que placés dans une enceinte close, ils ne sont plus en atmosphère poussièreuse, et de surcroît ils sont protégés de toute agression par les deux glaces qui les enferment entre elles. In their current use, they are in no way practical, while placed in a closed enclosure, they are no longer in a dusty atmosphere, and in addition they are protected from any attack by the two mirrors which enclose them between them.
L'invention s'applique aussi bien à un survitrage fixé au dormant d'une baie non ouvrante, qu'à un survitrage porté par le battant d'un châssis ouvrant. The invention applies equally well to a glazing fixed to the frame of a non-opening bay, as to a glazing carried by the wing of an opening frame.
