Abstract

The invention concerns an insulating window element (1) comprising at least one convex rigid pane (2), another rigid pane (3) and a spacer frame (4) that joins the two panes together using an impermeable adhesive, thus creating an interstice between the panes, said frame having a variable cross-section along its length, seen in the direction of its longitudinal extension in the region of the joint between the convex rigid pane (2) and the other rigid pane (3); according to the invention, the spacer frame (4) is composed, at least in the aforementioned region, of an elastomer material that is plastically deformed when the two rigid panes are pressed together (2, 3).

Description

ELEMENT DE VITRAGE ISOLANT COMPORTANT UNE VITRE BOMBEE INSULATING GLAZING ELEMENT COMPRISING A BOMBED GLASS
L'invention concerne un élément de vitrage isolant comportant une vitre bombée, qui présente les caractéristiques du préambule de la revendication 1.The invention relates to an insulating glazing element comprising a curved pane, which has the features of the preamble of claim 1.
Par élément de vitrage isolant au sens de la présente description, il faut comprendre un élément plat formé par au moins deux vitres rigides et un cadre d'écartement reliant ces deux vitres l'une à l'autre. Le cadre d'écartement est assemblé aux faces intérieures des vitres à l'aide de minces couches adhésives. Les deux faces principales tournées l'une vers l'autre des vitres rigides et le cadre d'écartement délimitent un interstice entre les vitres, qui est en règle générale fermé de façon étanche à l'air et a l'humidité. Par "rigide", on se réfère ici à la rigidité relative de vitres en verre et en matière plastique par comparaison avec des matériaux plus mous.By insulating glazing element within the meaning of the present description, it is necessary to understand a flat element formed by at least two rigid panes and a spacer frame connecting these two panes to one another. The spacer frame is assembled to the inner faces of the panes with thin adhesive layers. The two main faces facing each other of the rigid windows and the spacer frame define a gap between the panes, which is generally closed airtight and moisture-proof. "Rigid" refers here to the relative stiffness of glass and plastic windows compared to softer materials.
Pour les objectifs de l'invention décrite ici, on considère des vitres rigides en verre et en matière plastique, et ceci aussi bien sous forme monolithique que sous forme composite (au moins deux vitres rigides, assemblées l'une à l'autre par collage de surface avec une couche ou une feuille adhesive) . En outre, on peut utiliser aussi bien des vitres de verre précontraint, que partiellement précontraint ou non précontraint.For the purposes of the invention described here, rigid glass and plastic panes are considered, and this both in monolithic form and in composite form (at least two rigid panes, assembled to one another by gluing surface with an adhesive layer or sheet). In addition, one can use both prestressed glass panes, partially prestressed or non prestressed.
Le document EP 0 921 260 Bl divulgue un tel vitrage isolant avec une vitre rigide plane et une vitre rigide bombée sous forme cylindrique. Dans la région de la courbure relativement forte, le cadre d'écartement en forme de profilé creux de cet élément de vitrage est muni d'une nervure saillante, qui doit combler la fente en forme de croissant entre le profilé creux rectiligne et la vitre bombée. Une telle construction spéciale du cadre d'écartement est relativement compliquée et dès lors coûteuse.EP 0 921 260 B1 discloses such an insulating glazing unit with a flat rigid pane and a curved rigid pane in cylindrical form. In the region of the relatively strong curvature, the hollow profile-shaped spacer frame of this glazing element is provided with a projecting rib, which must fill the crescent-shaped slot between the straight hollow section and the curved window. . Such a special construction of the Spacer frame is relatively complicated and therefore expensive.
Par le document EP 1 657 396 A2 , on connaît un élément de vitrage isolant avec une vitre bombée sous forme cylindrique, dont le cadre d'écartement se compose d'un segment de profilé plein, par exemple en verre, dans la région de courbure précitée.Document EP 1 657 396 A2 discloses an insulating glazing element with a curved glass pane in cylindrical form, whose spacer frame consists of a solid profile segment, for example made of glass, in the region of curvature. supra.
Les cadres d'écartement en profilé creux sont la plupart du temps remplis avec un agent d'assèchement, qui extrait de l'interstice entre les vitres, dans une certaine mesure, toute humidité résiduelle et toute humidité pénétrant ultérieurement. De cette manière, on empêche durablement le dépôt de buée par l'intérieur sur les vitres, aussi longtemps qu'il ne se produit pas de dommage externe (par exemple bris de la vitre, détachement du collage entre le cadre d'écartement et les vitres) .Hollow profile spacers are usually filled with a dewatering agent, which extracts from the gap between the panes, to some extent, any residual moisture and any subsequent penetrating moisture. In this way, the deposition of condensation from the inside is permanently prevented on the windows, as long as no external damage occurs (for example breakage of the glass, detachment of the bonding between the spacer frame and the windows).
De même, le document DE 203 04 806 Ul décrit entre autres des éléments de vitrage isolants avec des vitres rigides bombées sous forme cylindrique, dans lesquels les deux vitres peuvent présenter des rayons de courbure différents. Le document est cependant muet au sujet de la réalisation du cadre d'écartement dans cette région de courbure.Similarly, the document DE 203 04 806 U1 discloses inter alia insulating glazing elements with curved rigid panes in cylindrical form, in which the two panes may have different radii of curvature. The document is however silent about the realization of the spacer frame in this region of curvature.
Il est largement connu de fabriquer des cadres d'écartement pour des éléments de vitrage isolants en un matériau élastomère, éventuellement thermoplastique, extrudable. Ceci a surtout pour objectif de minimiser le transfert de chaleur par conduction calorifique dans la région du bord des vitrages isolants (vitrages isolants "a bord chaud"). Ces cadres d'écartement élastomères imposent cependant encore d'autres mesures, pour que leur étanchéité contre la diffusion de vapeur d'eau puisse soutenir la comparaison avec les valeurs de cadres d'écartement métalliques. Le matériau élastomère seul ne suffit pas. Par conséquent, la plupart des cadres d' écartement elastomères comprennent encore des mserts métalliques supplémentaires, sont métallisés extérieurement ou sont munis d'un film mince. Il est également connu de mélanger ces matériaux avec des agents d'assèchement contre l'humidité dans l'interstice entre les vitres.It is widely known to manufacture spacer frames for insulating glazing elements in an elastomeric, possibly thermoplastic, extrudable material. The main purpose of this is to minimize heat transfer by heat conduction in the edge region of the insulating glazing units ("hot edge" insulating glazing units). These elastomeric spacers, however, still impose other measures, so that their sealing against the diffusion of water vapor can support the comparison with the values of metal spacer frames. The material elastomer alone is not enough. As a result, most elastomeric spacer frames still include additional metal meshes, are metallized externally or are provided with a thin film. It is also known to mix these materials with moisture dewatering agents in the interstice between the panes.
Le document EP 0 875 654 Al décrit un cadre d' écartement en profile creux en un matériau élastomère, dont la résistance mécanique est accrue par l'incorporation de fibres de verre.EP 0 875 654 A1 discloses a hollow profile spacer frame of an elastomeric material whose mechanical strength is increased by the incorporation of glass fibers.
Le document EP 1 195 497 A2 décrit la fabrication d'un élément de vitrage isolant avec un cadre d' écartement élastomère et encore déformable plastiquement après son dépôt (extrusion) sur une des vitres rigides. Pour que l'air déplacé lors de la pose de la deuxième vitre par compression du cadre d' écartement puisse s'échapper, sans que l'on doive d'abord prévoir une ouverture dans le cadre d' écartement, le cadre d'ecartement est d'abord, selon cette description, comprimé sur un côté plus fortement que ce qui est réellement nécessaire, alors que la vitre n'est pas encore posée sur le côté opposé. Puis la vitre est posée sur ce côté opposé du cadre d'ecartement, et ce dernier est comprime à son épaisseur de consigne. En l'occurrence, et jusqu'avant la fermeture de la dernière fente, l'air encore enfermé est déplacé plusieurs fois. Dans une dernière étape, le côté d'abord plus fortement comprimé du cadre d'ecartement est étendu à son "épaisseur de consigne". Le document ne concerne cependant pas la fabrication de vitres bombées dans un tel élément de vitrage isolant.The document EP 1 195 497 A2 describes the manufacture of an insulating glazing element with an elastomeric spacer frame and further plastically deformable after it has been deposited (extrusion) on one of the rigid panes. In order that the air displaced during the installation of the second window by compression of the spacer frame can escape, without first having to provide an opening in the spacer frame, the spacer frame is first, according to this description, compressed on one side more strongly than is really necessary, while the glass is not yet laid on the opposite side. Then the window is placed on this opposite side of the spacer frame, and the latter is compressed to its target thickness. In this case, and until before closing the last slot, the air still locked is moved several times. In a last step, the first more compressed side of the spacer frame is extended to its "setpoint thickness". The document does not however relate to the manufacture of curved panes in such an insulating glass element.
Par le document DE 30 02 904 Al ainsi que sous le nom commercial "Swiggle Strip", on connaît en outre un matériau élastomère avec un insert métallique flexible, par exemple pour des cadres d'ecartement d'éléments de vitrage isolants. Ce matériau convient également, selon les informations fournies par le site internet http: //www.bentglassdesign. com/glasstypes .html (Etat en janvier 2007), pour l'assemblage de deux vitres rigides bombées dans le même sens en un élément de vitrage isolant. Dans l'élément vitré bombé représenté ici, la distance entre les vitres est partout égale, même dans les régions courbes.By DE 30 02 904 A1 and under the trade name "Swiggle Strip", there is furthermore known an elastomeric material with a flexible metal insert, for example for spacer frames of insulating glazing elements. This material is also suitable, according to the information provided by the website http: //www.bentglassdesign. com / glasstypes .html (Status in January 2007), for the assembly of two rigid panes curved in the same direction into an insulating glass element. In the convex glazed element shown here, the distance between the panes is everywhere equal, even in the curved regions.
Le problème à la base de l'invention est de procurer un autre élément de vitrage isolant comportant au moins une vitre bombée et un cadre d1 écartement, qui présente une section transversale variable, considérée selon son extension longitudinale, dans la région de la courbure de la vitre.The problem underlying the invention is to provide another insulating glazing unit comprising at least one curved pane and a frame spacing d 1 which has a variable cross-section, considered along its longitudinal extent, in the bending region of the window.
Ce problème est résolu selon l'invention par les caractéristiques de la revendication 1. Les caractéristiques des revendications secondaires présentent des formes de réalisation avantageuses de cette invention.This problem is solved according to the invention by the features of claim 1. The features of the secondary claims show advantageous embodiments of this invention.
Partant des éléments de vitrage isolants connus comportant des vitres rigides bombées, la courbure du cadre d' écartement est obtenue selon l'invention par la déformation plastique du matériau du cadre d' écartement imposée lors du pressage de la vitre bombée. On le remarque sur le produit terminé parce que le cadre d' écartement présente des surépaisseurs locales dues au matériau déplace, qui sont naturellement plus épaisses dans la région de la plus grande déformation que dans la région de la plus grande hauteur d'arc. A l'extérieur de l'interstice entre les vitres, les surépaisseurs peuvent éventuellement être enlevées / éliminées. Indépendamment de cela, elles peuvent être masquées de façon connue par la pose d'un joint d'étanchéité extérieur ou secondaire (finition en polysulfure) . Le matériau décrit dans le document DE 30 02 904 Al convient bien pour ce cas d'application selon l'invention, éventuellement après certaines modifications qui seront encore décrites plus loin. Naturellement, d'autres matériaux analogues peuvent aussi être employés pour compenser les différences de courbure, dans la mesure où ils présentent la déformabilité plastique nécessaire. Il ne doit absolument pas s'agir dans ce document d'un matériau thermoplastique, qui doit d'abord être chauffé pour la déformation ou qui ne peut être déformé qu'à l'état encore chaud après la pose. Des matériaux déformables plastiquement de manière durable à la température ambiante conviennent en principe également, dans la mesure où ils présentent les valeurs de résistance nécessaires pour le composite isolant et une adhérence suffisante aux faces des vitres rigides.Starting from the known insulating glazing elements comprising curved rigid panes, the curvature of the spacer frame is obtained according to the invention by the plastic deformation of the spacer frame material imposed during the pressing of the curved pane. It is noted on the finished product because the spacer has local overthicknesses due to the moving material, which are naturally thicker in the region of greatest deformation than in the region of greatest arc height. Outside the gap between the panes, the extra thicknesses can optionally be removed / eliminated. Independently of this, they can be masked in known manner by the installation of an outer or secondary seal (polysulfide finish). The material described in DE 30 02 904 A1 is well suited for this case of application according to the invention, possibly after certain modifications which will be further described below. Of course, other similar materials may also be employed to compensate for differences in curvature, as long as they have the necessary plastic deformability. It must absolutely not be in this document a thermoplastic material, which must first be heated for deformation or can be deformed in the still hot state after installation. Durable plastically degradable materials at room temperature are also suitable in principle, since they have the required strength values for the insulating composite and sufficient adhesion to the faces of the rigid glass panes.
Même si le cas d'application préféré est la combinaison d'une vitre bombée et d'une vitre plane, deux vitres de courbure différente peuvent cependant aussi, selon l'invention, être assemblées l'une à l'autre en utilisant la capacité de compensation du cadre d'écartement élastomère dans la région des courbures différentes.Even if the preferred application case is the combination of a curved glass and a flat pane, two windows of different curvature can however also, according to the invention, be assembled to one another using the capacity compensation of the elastomeric spacer frame in the region of the different curvatures.
Naturellement, l'invention peut être appliquée non seulement avec des vitres bombées sous forme cylindrique, mais aussi avec des vitres bombées dans l'espace jusqu'à leurs arêtes, dans lesquelles il y a donc plus de deux arêtes latérales courbées à assembler avec le cadre d'écartement. Dans ce cas, on utilise la déformabilité du matériau du cadre d'écartement à chaque arête courbée, a laquelle il faut compenser des cintrages différents ou des courbures différentes entre les paires de vitres.Naturally, the invention can be applied not only with curved panes in cylindrical form, but also with curved panes in space up to their edges, in which there are therefore more than two curved side edges to be assembled with the spacer frame. In this case, the deformability of the spacer frame material is used at each curved edge, to which different bends or curvatures between the pairs of panes must be compensated.
Lors de la mise en œuvre de la présente invention, il peut être utile d'utiliser des hauteurs de base différentes pour le cadre d'écartement sur les arêtes sans courbure et sur les arêtes de la région de courbure, c'est-à-dire de réaliser celui-ci par exemple avec un total de quatre segments (deux paires de segments différentes) . Dans la région de la courbure, on utilisera une forme de réalisation plus large avec le volume de compression requis, dans la région sans courbure le profile peut être plus étroit. Ceci présente l'avantage que l'on ne doit pas comprimer le matériau aussi fortement sur les arêtes longitudinales. On pourrait aussi réaliser ainsi de plus grandes hauteurs d'arc.In the practice of the present invention, it may be useful to use basic heights different for the spacer on the edges without curvature and on the edges of the curvature region, that is to say to achieve it for example with a total of four segments (two pairs of different segments). In the region of the curvature, a wider embodiment with the required compression volume will be used, in the region without curvature the profile may be narrower. This has the advantage that the material should not be compressed so strongly on the longitudinal edges. We could also achieve greater arc heights.
L'inconvénient de cette forme de réalisation serait pourtant qu'il se trouve à chaque coin un point de soudure ou de jonction, qui doit aussi être rendu étanche .The disadvantage of this embodiment is that it is at each corner a weld or junction, which must also be sealed.
Dans une telle forme de réalisation, il serait également possible de fabriquer les segments du cadre d'écartement, dans lesquels aucune courbure n'est nécessaire, en un matériau conventionnel jusqu'aux cadres d'écartement métalliques usuels. On pourrait même imaginer de fabriquer tout le cadre d'écartement en profilés métalliques conventionnels et de ne munir ceux-ci que dans la région de courbure d'une couche de matériau plastiquement déformable et capable de compenser la courbure. On ne vise pas ici la compensation de petites inégalités d'une vitre (qui est naturellement possible aussi dans une faible mesure avec les matériaux adhésifs normaux entre le cadre d'écartement et la surface des vitres), mais exclusivement une compensation de différences de courbure avec des hauteurs d'arc de plusieurs millimètres.In such an embodiment, it would also be possible to manufacture the spacer frame segments, in which no curvature is required, from a conventional material to the usual metal spacer frames. One could even imagine making all the spacer frame of conventional metal profiles and to provide them only in the region of curvature of a layer of plastically deformable material and capable of compensating the curvature. It is not intended here to compensate for small unevenness of a window (which is of course also possible to a small extent with normal adhesive materials between the spacer frame and the window surface), but only compensation for differences in curvature with arc heights of several millimeters.
En outre, on peut mettre en œuvre l'invention, selon la hauteur de la courbure, avec des vitres prébombées ou aussi des vitres planes, dont la courbure n'est imposée que lors de la compression du cadre d ' écartement, dans le cadre de leur déformabilité élastique. Un tel "cintrage à froid" peut être conservé dans le produit fini a l'aide de la forte adhérence du cadre d' écartement, dans la mesure ou le matériau du cadre d1 écartement possède une stabilité de forme et une résistance au fluage à long terme suffisantes.In addition, it is possible to implement the invention, according to the height of the curvature, with pre-bent panes or also flat panes, the curvature of which is not imposed. only when compressing the spacer frame, as part of their elastic deformability. Such "cold-bending" can be retained in the finished product using the strong adhesion of the spacer frame, in so far as the distance d 1 frame material has a dimensional stability and creep resistance long term sufficient.
Enfin, des éléments fonctionnels électriques et/ou électroniques peuvent, de façon connue en soi, être incorporés ou intégrés dans un tel élément de vitrage isolant. Ceux-ci peuvent se trouver aussi bien dans l'interstice entre les vitres qu'à l'intérieur d'une vitre feuilletée utilisée comme vitre rigide, si l'on ne peut pas ou si l'on ne veut pas les installer sur une des faces extérieures. On peut envisager ici par exemple des éléments fonctionnels tels que des écrans électrochromes ou électroluminescents, des lampes, des écrans d'affichage, des cellules solaires, des capteurs et des indicateurs, des éléments chauffants et/ou des antennes. De même, des éléments non électriques, comme par exemple des éléments de surface thermochromes ou photochromes, tels que des revêtements naturellement transparents et/ou opaques, en particulier des barrières thermiques et/ou des filtres de lumière et/ou de couleur, peuvent être combinés avec des éléments de vitrage isolants selon l'invention.Finally, electrical and / or electronic functional elements may, in a manner known per se, be incorporated or integrated in such an insulating glazing element. These can be found both in the gap between the windows and inside a laminated glass used as rigid glass, if we can not or if we do not want to install them on a outer faces. For example, functional elements such as electrochromic or electroluminescent screens, lamps, display screens, solar cells, sensors and indicators, heating elements and / or antennas can be envisaged. Likewise, non-electrical elements, such as for example thermochromic or photochromic surface elements, such as naturally transparent and / or opaque coatings, in particular thermal barriers and / or light and / or color filters, may be combined with insulating glazing elements according to the invention.
Des éléments de vitrage isolants du type décrit ici conviennent pour des utilisations les plus diverses, aussi bien dans des véhicules que dans des bâtiments. Par exemple, ces éléments de vitrage isolants peuvent être utilises pour les vitrages de véhicules - par exemple dans des bus - et la de préférence dans la région du passage du vitrage latéral au toit. La vitre bombée est alors placée du côté extérieur et elle est adaptée dans le contour extérieur. La vitre intérieure plane ou bombée différemment peut alors être pourvue d'éléments fonctionnels supplémentaires, par exemple des lampes de surface ou d'autres équipements additionnels .Insulating glazing elements of the type described herein are suitable for a wide variety of uses, both in vehicles and in buildings. For example, these insulating glazing elements may be used for vehicle glazings - for example in buses - and preferably in the region of the passage of the side glazing to the roof. The curved glass is then placed on the outside and is adapted in the outer contour. The inner pane flat or curved differently can then be provided with additional functional elements, for example surface lamps or other additional equipment.
D'autres détails et avantages de l'objet de l'invention apparaîtront par les dessins d'un exemple de réalisation et par sa description détaillée qui suit.Other details and advantages of the subject of the invention will become apparent from the drawings of an exemplary embodiment and from its detailed description which follows.
Dans ces dessins, qui sont des représentations schématiques sans échelle particulière,In these drawings, which are schematic representations without a particular scale,
La Fig. 1 est une vue d'un élément de vitrage isolant réalise selon l'invention; La Fig. 2 est une vue en coupe du même élément de vitrage isolant le long de la ligne de coupe II-II indiquée dans la Figure 1 ;Fig. 1 is a view of an insulating glazing element produced according to the invention; Fig. 2 is a sectional view of the same insulating glazing element along section line II-II shown in FIG. 1;
La Fig. 3 montre deux vues de segments du cadre d'ecartement pour l'élément de vitrage isolant selon les Figures 1 et 2 ;Fig. Fig. 3 shows two segment views of the spacer frame for the insulating glazing element according to Figs. 1 and 2;
La Fig. 4 est une représentation éclatée d'un élément de vitrage isolant selon l'invention avant la pose de la vitre rigide bombée sur le cadre d'ecartement préparé.Fig. 4 is an exploded representation of an insulating glazing element according to the invention prior to the installation of the curved rigid pane on the prepared spacer frame.
Dans la Figure 1, on peut voir une vue en plan d'un élément de vitrage isolant 1 comportant une vitre rigide bombée supérieure 2 et une vitre rigide plane sous-jacente 3. Dans la forme de réalisation discutée ici, celle-ci dépasse de quelques centimètres le contour de la vitre bombée 2, de façon à former un élément de vitrage isolant échelonné.In FIG. 1, a plan view of an insulating glazing element 1 comprising an upper curved rigid pane 2 and an underlying flat rigid pane 3 can be seen. In the embodiment discussed here, this exceeds a few centimeters the contour of the curved pane 2, so as to form an insulating glazing element staggered.
En dessous de la vitre supérieure 2, on a indiqué le contour d'un cadre d'ecartement 4, qui s'étend en périphérie sur tout le périmètre de l'élément de vitrage isolant 1 et qui délimite, avec les faces intérieures principales des deux vitres rigides 2 et 3, un interstice entre les vitres étanche à l'air et à 1 ' humidité . Le repère 5 désigne le bord intérieur d'une couche colorée par nature opaque, qui est déposée en forme de cadre sur la face intérieure d'une ou des deux vitres rigides 2 / 3 et qui entoure le champ de vision proprement dit de l'élément de vitrage isolant par ailleurs transparent. Cette couche colorée sert d'une part - de façon connue en soi - à masquer visuellement le cadre d'ecartement elastomère 4 ainsi que ses liaisons collées avec les deux vitres rigides, d'autre part à protéger le matériau elastomère et les couches ou les cordons de colle contre le rayonnement UV et contre la fragilisation / la perte d'adhérence qui en résulte à long terme.Below the upper window 2 is indicated the outline of a spacer frame 4, which extends peripherally over the entire perimeter of the insulating glazing element 1 and which delimits, with the main inner faces of the two rigid panes 2 and 3, a gap between the panes airtight and moisture. The reference numeral 5 designates the inner edge of an opaque colored layer, which is deposited in the form of a frame on the inner face of one or both rigid panes 2/3 and which surrounds the field of view itself of the insulating glazing element which is otherwise transparent. This colored layer serves on the one hand - in a manner known per se - to visually mask the elastomeric spacer frame 4 and its bonded connections with the two rigid panes, on the other hand to protect the elastomeric material and the layers or the glue beads against UV radiation and against the embrittlement / loss of adhesion that results in long-term.
La couche colorée opaque n'est pas opaque dans la représentation, pour des raisons de visibilité du cadre d'ecartement. Elle peut du reste s'étendre également au-delà du bord saillant d'un côté de la vitre 3.The opaque colored layer is not opaque in the representation, for reasons of visibility of the spacer frame. It can also extend beyond the protruding edge of one side of the window 3.
La courbure de la vitre 2 n'est pas visible dans laThe curvature of the window 2 is not visible in the
Figure 1, parce qu'elle se soulevé dans le sens contraire au sens du regard, donc hors du plan du dessin.Figure 1, because it is raised in the opposite direction to the direction of the gaze, so out of the plane of the drawing.
Un regard sur la coupe selon la ligne II-II de la Figure 1, représentée dans la Figure 2, illustre la forme et la configuration du cadre d'ecartement 4 dans la région de courbure. Dans le reste du périmètre de l'élément de vitrage, la ou les bords des vitres sont parallèles entre eux (arêtes longitudinales) , le cadre d'ecartement est simplement rectiligne et a une section transversale constante. Comme on l'a déjà mentionne, il peut aussi y être réalisé avec des segments de cadre en profilé métallique conventionnels.A look at the section along the line II-II of Figure 1, shown in Figure 2, illustrates the shape and configuration of the spacer frame 4 in the curvature region. In the rest of the perimeter of the glazing element, where the edges of the panes are parallel to each other (longitudinal edges), the spacer frame is straight and has a constant cross section. As already mentioned, it can also be realized with conventional metal profile frame segments.
On soulignera que la hauteur d'arc au-dessus de la corde dans la région de courbure (ici le long des arêtes latérales courtes de l'élément de vitrage isolant) peut se situer dans la plage de quelques millimètres (entre > 0 et environ 6 mm) en fonction de la longueur de la corde. A titre d'exemple, on mentionnera un rayon de courbure d'environ 2000 mm pour une corde d'environ 300 mm avec une épaisseur de verre de 4 mm. Il en résulte une hauteur d'arc maximale au- dessus de la corde d'environ 5,5 mm.It should be emphasized that the arc height above the chord in the curvature region (here along the short side edges of the insulating glazing element) may be in the range of a few millimeters (between> 0 and about 6 mm) depending on the length of the rope. By way of example, mention will be made of a radius of curvature of about 2000 mm for a rope of about 300 mm with a glass thickness of 4 mm. This results in a maximum arc height above the rope of about 5.5 mm.
Dans la Figure 2, on voit en outre d'une part que le cadre d'ecartement 4 est renforcé par un insert métallique 4M non visible dans la Figure 1. Cet insert 4M possède une section transversale constante. Le matériau brut pour le cadre d'ecartement 4 est fabriqué sans fin sous forme de profile extrudé (par exemple coextrudé) et coupé à la longueur nécessaire. En l'occurrence, il n'est pas particulièrement difficile d'obturer suffisamment bien les points de soudure entre des segments de profilé, parce que le matériau est très bien déformable plastiquement, et possède aussi une bonne adhérence pour les matières usuelles de remplissage, d'étanchéité et de collage.In Figure 2, it is further seen firstly that the spacer frame 4 is reinforced by a metal insert 4M not visible in Figure 1. This 4M insert has a constant cross section. The raw material for the spacer frame 4 is made endlessly in extruded profile form (eg coextruded) and cut to the required length. In this case, it is not particularly difficult to seal the weld points sufficiently between profile segments, because the material is very well plastically deformable, and also has a good adhesion for the usual filling materials, sealing and bonding.
Quoi qu'il en soit, les zones de coin, qui se trouvent dans cette représentation des deux côtés du segment visible du cadre d'ecartement 4, peuvent être produites sans difficulté par flexion du matériau. Comme on le voit par comparaison avec la Figure 1, les segments de cadre rectilignes des côtés longitudinaux de l'élément de vitrage isolant, dans lesquels la section transversale est invariable, se raccordent à ces zones de coin.In any case, the corner areas, which are in this representation on both sides of the visible segment of the spacer frame 4, can be produced without difficulty by bending the material. As can be seen by comparison with FIG. 1, the rectilinear frame segments of the longitudinal sides of the insulating glazing element, in which the cross section is invariable, connect to these corner areas.
On peut également voir dans la Figure 2 que le cadre d'ecartement 4 est légèrement en retrait vers l'intérieur, en périphérie, par rapport aux arêtes extérieures des deux vitres 2 et 3. Dans la rainure périphérique qui subsiste, on place de façon connue en soi, après l'achèvement du collage entre le cadre d'ecartement et les vitres rigides, un joint d'étanchéité secondaire en polysulfure, non représenté ici, qui remplit de préférence entièrement la rainure.It can also be seen in Figure 2 that the spacer frame 4 is slightly inwardly withdrawn, peripherally, with respect to the outer edges of the two panes 2 and 3. In the remaining peripheral groove, it is placed known per se, after the completion of bonding between the spacer and the rigid windows, a seal A secondary polysulfide seal, not shown here, which preferably completely fills the groove.
On voit enfin que, dans la forme de réalisation illustrée ici, 1 ' insert métallique 4M est légèrement décentré par rapport à l'extension longitudinale du cadre d'écartement 4.Finally, it can be seen that, in the embodiment illustrated here, the metal insert 4M is slightly off-center with respect to the longitudinal extension of the spacer frame 4.
Dans la Figure 3, ceci est représenté à une échelle légèrement plus grande au moyen d'une vue en élévation et d'une section transversale rabattue à droite. Cette mesure n'est certes pas absolument nécessaire pour la fabrication d'un élément de vitrage isolant selon l'invention, mais on peut aussi travailler avec les profilés symétriques conventionnels, dans la mesure où il y a suffisamment de matériau élastomère déplaçable à côté de l' insert.In Figure 3, this is shown on a slightly larger scale by means of an elevational view and a cross section folded to the right. This measure is certainly not absolutely necessary for the manufacture of an insulating glazing element according to the invention, but it is also possible to work with conventional symmetrical sections, insofar as there is sufficient elastomeric material that can be displaced next to the insert.
La forme de réalisation de base de ce cadre d'écartement est connue par le document DE 30 02 904 Al mentionné dans l'introduction. On procure ici une autre variante, en ce que 1 ' insert métallique 4M est ouvert en direction d'un côté ou, en d'autres termes, est noyé dans le matériau élastomère dans un canal ouvert d'un côté. A l'état monté, l'ouverture du canal est située à l'extérieur, donc à l'opposé de l'interstice entre les vitres, et elle n'est pas visible pour l'observateur.The basic embodiment of this spacer frame is known from DE 30 02 904 A1 mentioned in the introduction. Another variant is provided in that the metal insert 4M is open towards one side or, in other words, is embedded in the elastomeric material in an open channel on one side. In the mounted state, the opening of the channel is located outside, so the opposite of the gap between the panes, and it is not visible to the observer.
Sur le côté tourné vers l'interstice entre les vitres, le cadre d'écartement présente une image unitaire fermée.On the side facing the gap between the panes, the spacer frame has a closed unit image.
La compression du cadre d'écartement 4 à partir de l'état initial (montré par exemple dans la Figure 3) et de l'état déformé entre la vitre bombée 2 et la vitre plane 3 avec une section transversale variable en direction longitudinale (indiqué dans la Figure 3 par une ligne courbe interrompue avec un fort raccourcissement en perspective de l'arc possible) se produit en direction de l'extension transversale de 1 ' insert métallique 4M par nature plat, mais légèrement ondulé pour faciliter les déformations (flexions) . Par conséquent, sa largeur doit être partout inférieure à la distance minimale entre les deux vitres rigides 2 / 3, afin que le métal ne vienne pas en contact avec les faces des vitres.The compression of the spacer frame 4 from the initial state (shown for example in FIG. 3) and the deformed state between the curved glass pane 2 and the flat pane 3 with a longitudinally variable cross section (indicated in FIG. in Figure 3 by a broken curved line with a strong shortening in perspective of the possible arc) occurs in the direction of the transversal extension of 1 'metal insert 4M by nature flat, but slightly wavy to facilitate the deformations (bending). Therefore, its width must be everywhere less than the minimum distance between the two rigid panes 2/3, so that the metal does not come into contact with the faces of the panes.
L'ouverture unilatérale du canal formé dans le matériau élastomère du cadre d'écartement pour 1 ' insert métallique 4M facilite le déplacement du matériau élastomère nécessaire pour la variation de la section transversale. Celui-ci s'écoule à l'état comprime d'une part vers le côté (le cadre d'écartement y devient donc légèrement plus épais), il peut cependant aussi être déplacé dans le canal d'abord ouvert et combler celui- ci partiellement ou entièrement. Au besoin, soit on déformera le matériau élastomère du cadre d'écartement encore à l'état chaud après le dépôt à chaud, soit on le chauffera pour cette opération de déformation, dans la mesure où il n'est pas suffisamment deformable plastiquement aux températures usuelles de mise en œuvre (température ambiante) .The unilateral opening of the channel formed in the elastomeric material of the spacer frame for the 4M metal insert facilitates the displacement of the elastomeric material required for cross-sectional variation. The latter flows in a compressed state on the one hand to the side (the spacer becomes slightly thicker), but it can also be moved into the open first channel and fill it. partially or entirely. If necessary, either the elastomeric material of the spacer frame will be deformed in the hot state after the hot deposition, or it will be heated for this deformation operation, insofar as it is not sufficiently plastically deformable at temperatures usual implementation (ambient temperature).
La Figure 4 est une représentation éclatée montrant, à titre d'exemple, sous forme de dessin evide, les différentes pièces nécessaires pour la composition d'un élément de vitrage isolant 1 selon l'invention avant la pose de la vitre bombée 2. Celle-ci a sa forme de base bombée (courbée) déjà avant la pose. Elle est également munie d'une couche d'encadrement colorée, opaque en réalité mais indiquée uniquement par son bord intérieur 5, comme dans la Figure 1. Sur la vitre plane 3, on a disposé, le long de ses arêtes extérieures et avec un léger retrait vers l'intérieur, quatre segments d'un profilé d'écartement, chaque fois deux segments 4.1 et 4.2. On voit bien que les segments 4.2, qui seront adaptés aux arêtes courbées de la vitre 2, sont plus hauts que les segments 4.1 le long des arêtes longitudinales rectilignes de l'élément de vitrage isolant 1. On a trace dans les segments 4.2 une ligne en traits interrompus 4A, qui reproduit l'arc des arêtes de la vitre bombée, et ainsi aussi le contour que ces segments 4.2 prennent après la pose et le pressage de la vitre bombée.FIG. 4 is an exploded representation showing, by way of example, in the form of an evidenced drawing, the various parts necessary for the composition of an insulating glazing element 1 according to the invention before the curved glass pane 2 is laid. it has its curved base shape (curved) already before laying. It is also provided with a colored framing layer, opaque in reality but indicated only by its inner edge 5, as in Figure 1. On the flat pane 3, is disposed along its outer edges and with a slightly inward withdrawal, four segments of a spacer profile, each time two segments 4.1 and 4.2. It is clear that the segments 4.2, which will be adapted to the curved edges of the pane 2, are higher than the segments 4.1 along the rectilinear longitudinal edges of the glazing element. In the segments 4.2, a dashed line 4A has been drawn, which reproduces the arc of the edges of the curved pane, and thus also the contour that these segments 4.2 take after the installation and pressing of the curved pane.
On peut atteindre de différentes manières l'état de déformation de la vitre bombée 2 illustré dans la Figure 2 et indique dans la Figure 4. En règle générale, on pose une vitre 2 préalablement bombée sous forme cylindrique sur le cadre d'écartement déjà déposé sur la vitre plane 3, et on approche par pressage, éventuellement en plusieurs étapes, les bords (longitudinaux) vers la vitre plane 3, jusqu'à ce que la plus haute région de l'arc de la courbure de la vitre 2 soit également assemblée de façon sûre par collage au cadre d'écartement 4. Dans cette région du sommet également, on provoquera donc par sécurité au moins une légère déformation par compression du matériau élastomere. Une vitre préalablement bombée 2 n'est pas nécessairement encore déformée davantage lors de cette opération, sauf éventuellement dans la région d'une déformation élastique, un support de surface de l'arc entier étant possible ici au besoin pour éviter la rupture.The state of deformation of the curved pane 2 illustrated in FIG. 2 can be achieved in different ways and indicated in FIG. 4. As a general rule, a previously curved pane 2 is placed in cylindrical form on the spacer frame already deposited. on the flat pane 3, and the (longitudinal) edges are approached by pressing, possibly in several stages, towards the flat pane 3, until the highest region of the arc of the curvature of the pane 2 is also assembled in a secure manner by gluing to the spacer frame 4. In this region of the summit also, it will therefore cause for safety at least a slight deformation by compression of the elastomeric material. A previously curved window 2 is not necessarily further deformed during this operation, except possibly in the region of an elastic deformation, a surface support of the entire arc being possible here if necessary to avoid breakage.
On peut cependant aussi déformer à froid la vitre bombée 2, dans sa plage de deformabilité élastique, par une opération de pressage analogue à partir d'une forme initialement plane, lorsque la matière de la vitre n'est pas trop épaisse. Avec une telle forme initiale, si l'on ne charge que les arêtes (longitudinales), il s'établira forcement une courbure de la vitre due à la réaction du cadre d'écartement 4 à déformer. On peut en plus atteindre une mesure définie de la hauteur d'arc par un support central dans la région de courbureHowever, it is also possible to cold deform the curved window 2, in its elastic deformability range, by a similar pressing operation from an initially flat shape, when the material of the window is not too thick. With such an initial shape, if one loads only the edges (longitudinal), it will necessarily establish a curvature of the window due to the reaction of the spacer frame 4 to deform. In addition, a defined measure of the arc height can be achieved by a central support in the curvature region
(efficace entre les faces intérieures des deux vitres rigides dans la région de la rainure extérieure périphérique) ou aussi par un gabarit de courbure placé temporairement entre les deux vitres rigides parallèlement au cadre d'ecartement a déformer.(effective between the inner faces of the two rigid windows in the region of the peripheral outer groove) or also by a curvature template placed temporarily between the two rigid panes parallel to the spacer frame to deform.
Bien entendu, on peut aussi envisager des combinaisons des deux procèdes. Par exemple, on peut amener elastiquement a sa forme courbée finale pendant l'opération de pressage une vitre initialement légèrement prebombee. Ceci présente l'avantage que les forces de rappel agissant sur le cadre d'ecartement colle ne sont pas aussi élevées que pour une vitre va froid a partir de l'état plan.Of course, it is also possible to envisage combinations of the two processes. For example, it is possible to bring to its final curved shape during the pressing operation an initially slightly pre-bent window. This has the advantage that the restoring forces acting on the spacing glue frame are not as high as for a glass goes cold from the plane state.
Apres le durcissement, la liaison, etc., final des assemblages colles entre le cadre d'ecartement et les vitres rigides, et aussi après la solidification du matériau elastomere lui-même, la vitre bombée elastiquement conservera la forme désirée sans que l'on doive prendre d'autres mesures. Une telle façon de procéder est connue en soi également pour des vitres feuilletées bombées. After hardening, bonding, etc., final assemblies glued between the spacer and the rigid pane, and also after the solidification of the elastomer material itself, the curved glass elastically retain the desired shape without it must take other measures. Such a procedure is known per se also for curved laminated panes.
