Abstract

The window has two glass panels joined together with spacers and seals between their inner surfaces. One inner element (17) is attached to the panels by butyl joints (19), for example, separated from an inner spacer frame member (15) by a polysulphide elastomer strip (18). The inner spacer frame member (15) has elastomer seals (21) between it and the glass panels, and is attached to an outer surrounding frame (14) by fixing screws (16). The outer glass panel (20) of the window can be larger than the inner one, with its edge overlapping part of the surrounding frame.

Description

L'invention concerne un panneau vitré comportant un cadre dans lequel est installé un vitrage isolant comportant deux ou plusieurs feuilles de matériaux transparents. Les panneaux du type précédent sont destinés à constituer des vantaux fixes ou des vantaux mobiles de fenêtre. Les cadres sont faits de matériaux divers : bois, métal tel que l'aluminium, ou matières plastiques. Les vitrages sont faits le plus souvent de verre silicosodo-calcique.The invention relates to a glazed panel comprising a frame in which is installed insulating glazing comprising two or more sheets of transparent materials. The panels of the previous type are intended to constitute fixed leaves or leaves window mobiles. The frames are made of various materials: wood, metal such as aluminum, or plastics. The glazing is most often made of silica-calcium glass.

Le plus souvent, traditionnellement, les panneaux vitrés possèdent un cadre qui a une section en forme de L, le vitrage, comme par exemple, un vitrage isolant venant s'installer à l'intérieur du L par l'intermédiaire de cales à sa périphérie et de produits d'étanchéité sur ses faces. Du côté du vitrage opposé au coin du L, la fixation se fait à l'aide d'une baguette dite pareclose. Les panneaux vitrés du type précédent ont ainsi des cadres dans lequel le vitrage vient s'insérer. Il est donc nécessaire que l'épaisseur du cadre terminé avec sa pareclose soit nettement supérieure à l'épaisseur du vitrage.Most often, traditionally, the glass panels have a frame which has an L-shaped section, the glazing, such as for example an insulating glazing coming from settle inside the L by means of shims at its periphery and products sealing on its faces. On the side of the glazing opposite the corner of the L, the fixing is done at using a rod called a glazing bead. The glass panels of the previous type thus have frames in which the glazing is inserted. It is therefore necessary that the thickness of the frame finished with its glazing bead is significantly greater than the thickness of the glazing.

Lorsque le vitrage est un verre simple, de 2 ou 3 millimètres, l'épaisseur du cadre reste raisonnable et correspond aux nécessités mécaniques pour que le vitrage puisse résister aux sollicitations diverses comme celles du vent, ou aux chocs liés à l'ouverture et la fermeture d'un ouvrant. Il en va différemment lorsque le vitrage est un vitrage isolant et spécialement du type de ceux qui comportent une lame d'air de 12 mm ou davantage puisqu'alors le vitrage atteint et dépasse des épaisseurs de l'ordre de 20 mm, ce qui nécessite d'augmenter très sensiblement l'épaisseur des cadres des panneaux vitrés.When the glazing is a simple glass, 2 or 3 millimeters, the thickness of the frame remains reasonable and corresponds to the mechanical necessities so that the glazing can withstand various stresses such as wind, or shocks related to the opening and closing an opening. It is different when the glazing is insulating glazing and specially of the type having an air gap of 12 mm or more since then the glazing reaches and exceeds thicknesses of the order of 20 mm, which requires a very substantial increase in the thickness of the glass panel frames.

On a vu ainsi apparaítre récemment des vitrages isolants à isolation thermique améliorée, l'une des parois du vitrage isolant est recouverte intérieurement d'une couche mince à basse émissivité et l'espace intercalaire, porté à 15 mm est rempli d'argon. Par rapport à certains vitrages isolants de la première génération 4 (6) 4, on a là aussi un accroissement important de l'épaisseur.We have seen recently appear insulating glazing with thermal insulation improved, one of the walls of the insulating glazing is internally covered with a layer thin with low emissivity and the spacer space, increased to 15 mm, is filled with argon. Through compared to certain first generation insulating glazing 4 (6) 4, here too there is a significant increase in thickness.

L'augmentation des épaisseurs des châssis nécessitée par l'accroissement proportionnel des épaisseurs des vitrages a entraíné une augmentation des coûts. Par ailleurs, les préoccupations concernant l'environnement poussent à limiter les quantités de matières utilisées pour remplir une fonction donnée. Il serait très important - en particulier avec le bois - de pouvoir revenir à des épaisseurs de châssis aussi faibles que possible. En effet, les autres fonctions exigées de la fenêtre et que le châssis contribue à remplir telles que tenue au vent, résistance mécanique, étanchéité pourraient l'être avec des épaisseurs de châssis bien inférieures à celles qu'impose l'accroissement d'épaisseurs des vitrages.The increase in the thickness of the frames required by the increase proportional to the thickness of the glazing has led to an increase in costs. Through elsewhere, concerns about the environment lead to limiting the quantities of materials used to perform a given function. It would be very important - especially with wood - to be able to return to chassis thicknesses as small as possible. In indeed, the other required functions of the window and that the sash helps to fulfill such that wind resistance, mechanical resistance, tightness could be with thicknesses of chassis much lower than those required by the increased thickness of the glazing.

On connaít des techniques qui permettent d'associer mécaniquement et structurellement un vitrage et des profilés qui constituent le cadre dans lequel il doit être inséré. Dans le document US-4 134 238 on présente ainsi un vitrage équipé de cavaliers en général métalliques, collés à sa périphérie sur les quatre côtés du vitrage dans lesquels il est possible de venir visser différents éléments et en particulier des profilés, notamment en aluminium, qui constituent le cadre d'une fenêtre ou d'un vantail de fenêtre. Cette technique qui est particulièrement bien adaptée aux menuiseries métalliques présente cependant quelques inconvénients. La technique de collage des cavaliers à la périphérie du vitrage n'est pas très simple. C'est une opération qui nécessite une reprise du vitrage isolant après sa fabrication et qui est coûteuse en main d'oeuvre. Par ailleurs, il est nécessaire de prévoir les trous par où vont passer des vis qui viennent fixer les profilés sur les chants du vitrage avec une grande précision de manière à ce qu'il n'y ait pas de contraintes latérales qui s'exercent sur les cavaliers lorsque l'on procède au vissage. Par ailleurs, la technique précédente nécessite de cacher la partie des cavaliers qui se trouve sur la surface externe du vitrage. D'autre part, traditionnellement, dans une fenêtre, l'ouvrant et le dormant sont ajustés l'un à l'autre et les tolérances de fabrication sont rattrapées grâce au jeu qui existe entre le vitrage et son châssis, des cales assurant l'immobilisation de l'un dans l'autre. Avec la méthode proposée dans US 4 134 238 c'est entre le dormant et l'ouvrant qu'il s'agissait de prévoir cet ajustement ce qui posait des problèmes délicats au fabricant de châssis.We know techniques that allow to combine mechanically and structurally glazing and profiles which constitute the framework in which it must be inserted. Document US-4,134,238 thus presents a glazing unit fitted with jumpers in general metallic, glued at its periphery on the four sides of the glazing in which it is possible to screw different elements and in particular profiles, especially in aluminum, which form the frame of a window or window sash. This technique which is particularly well suited to metal joinery presents however some drawbacks. The technique of bonding the riders to the periphery of the glazing is not very simple. It is an operation which requires a resumption of the glazing insulation after its manufacture and which is costly in labor. Furthermore, it is necessary to provide the holes through which will pass screws which come to fix the profiles on the glazing edges with great precision so that there is no lateral stresses which are exerted on the jumpers when one proceeds to the screwing. Through elsewhere, the previous technique requires hiding the part of the jumpers that is on the external surface of the glazing. On the other hand, traditionally, in a window, opening and the frame are adjusted to each other and the manufacturing tolerances are made up thanks to the clearance between the glazing and its frame, wedges ensuring the immobilization of one in the other. With the method proposed in US 4,134,238 it is between the frame and opening it that it was a question of foreseeing this adjustment what posed delicate problems with chassis manufacturer.

Le document EP-A-0 412 669 propose une technique qui permet de rattraper les jeux existant entre un vitrage de dimensions données et un cadre constituant un châssis de fenêtre de dimensions intérieures légèrement supérieures à celles du vitrage. Dans ce document, on propose des cales ajustables constituées de deux parties à section triangulaires qui forment à elles-deux une cale plate à faces parallèles mais qui permettent, grâce au déplacement d'une partie par rapport à l'autre, de varier l'épaisseur de la cale. Document EP-A-0 412 669 proposes a technique which makes it possible to catch up with clearances between glazing of given dimensions and a frame constituting a frame of window with interior dimensions slightly larger than those of the glazing. In this document, we offer adjustable shims made up of two section parts triangular which together form a flat wedge with parallel faces but which allow, thanks to the displacement of one part relative to the other, to vary the thickness of the shim.

Dans EP-A-0 412 669, la conception des cales réglables en épaisseur ne permet pas d'assurer la fixation latérale des vitrages dans le châssis en l'absence de tout maintien extérieur dépassant des surfaces externes des vitrages. Il est nécessaire selon la technique de EP-A-0 412 669, de prévoir des systèmes de maintien latéral qui accroissent l'épaisseur hors tout de l'ensemble vitrage-profilés du cadre.In EP-A-0 412 669, the design of the shims adjustable in thickness does not does not allow lateral fixing of the glazing in the frame in the absence any external support extending beyond the external surfaces of the glazing. It is necessary according to the technique of EP-A-0 412 669, to provide systems for lateral support which increases the overall thickness of the glazing-profiles assembly of the frame.

Enfin, le document EP 0 228 641 propose un double-vitrage fixé à un cadre au moyen d'éléments profilés qui comportent une partie centrale insérée et fixée entre les deux vitres du vitrage et une partie d'assise associée au cadre. La partie d'assise constitue un gorge dans laquelle se loge une pièce rapportée qui est vissée à une partie du cadre.Finally, document EP 0 228 641 proposes double glazing fixed to a frame by means of profiled elements which have an inserted central part and fixed between the two panes of glazing and a seat part associated with the frame. The seat part constitutes a groove in which is housed an attached part which is screwed to part of the frame.

Bien que les éléments profilés de ce document permettent de diminuer sensiblement l'épaisseur du châssis, la fixation de ceux-ci au cadre n'est cependant pas simple car nécessitant une pièce supplémentaire et de la visserie, moyens, qui par ailleurs, ne sont pas de mise en oeuvre rapide et peuvent se désengager au cours du temps engendrant une fixation peu fiable.Although the profiled elements of this document allow to decrease substantially the thickness of the chassis, the fixing of these to the frame is not however not simple because requiring an additional room and screws, means, which moreover, are not of rapid implementation and can be disengage over time resulting in unreliable attachment.

Le problème technique que l'invention se donne pour tâche de résoudre est de trouver un système de fixation d'un vitrage dans une baie qui permette de diminuer sensiblement l'épaisseur des châssis, soit compatible avec les techniques de montage traditionnelles mais tout en étant facile et rapide de mise en oeuvre.The technical problem which the invention sets itself the task of solving is to find a system for fixing a glazing in a bay that allows significantly reduce the thickness of the chassis, i.e. compatible with traditional mounting techniques but while being easy and quick to set up in action.

D'autre part, l'invention doit permettre d'obtenir toutes les caractéristiques du panneau vitré nécessaires, telles que la tenue mécanique ou l'étanchéité du panneau. Pour atteindre ce but, l'invention propose un panneau vitré comportant un vitrage isolant et des éléments de cadre fixés le long des côtés du vitrage de manière à limiter leurs déplacements relatifs perpendiculairement au vitrage, le vitrage et les éléments de cadre étant associés mécaniquement par une pièce mécanique de liaison qui comporte un organe de fixation de la pièce au vitrage s'insérant au moins localement entre les deux vitres du vitrage isolant, caractérisé en ce que la pièce mécanique de liaison comporte un élément déformable destiné à coopérer par encliquetage avec un élément d'accueil correspondant des éléments de cadre pour, après mise en place du vitrage dans les éléments de cadre, le bloquer perpendiculairement à sa surface. On the other hand, the invention must make it possible to obtain all the required glass panel characteristics, such as mechanical strength or the sealing of the panel. To achieve this goal, the invention provides a panel glazed with insulating glazing and frame elements fixed along the sides of the glazing so as to limit their relative displacements perpendicular to the glazing, the glazing and the frame elements being associated mechanically by a mechanical connecting piece which comprises a fixing the part to the glazing fitting at least locally between the two insulating glass panes, characterized in that the mechanical connecting part comprises a deformable element intended to cooperate by snap-fastening with a matching home element frame elements for, after setting place the glazing in the frame elements, block it perpendicular to its area.

De préférence après sa déformation et sa mise en place en position de blocage du vitrage, l'élément déformable ne peut plus quitter cette position. Ce système de blocage des pièces mécaniques intermédiaires, collées ou au moins liées au vitrage, permet de fixer le vitrage dans son plan d'une manière très simple. Selon une première variante, le cadre possède une huisserie équipée d'au moins une rainure et alors, l'élément déformable est une patte qui s'insère dans la rainure. L'autre variante, dans laquelle le cadre possède une huisserie équipée d'au moins une nervure et où l'élément déformable est une patte qui, en position de blocage, enserre ladite nervure fonctionne exactement selon le même principe. Avantageusement, la pièce mécanique intermédiaire a une dimension réglable dans la direction du plan du vitrage. Pour réaliser ce réglage, on propose que la pièce mécanique comporte deux parties prismatiques comportant chacune un plan incliné en contact avec celui de l'autre partie, et que le déplacement d'un plan incliné par rapport à l'autre modifie la dimension de la pièce mécanique dans le plan du vitrage. Pour éviter tout déréglage, l'invention prévoit que les plans inclinés comportent des gradins dont la forme est telle que le déplacement d'un plan en contact avec l'autre n'autorise que l'accroissement de la dimension de la pièce mécanique dans le plan du vitrage.Preferably after its deformation and its positioning in the position of glass blocking, the deformable element can no longer leave this position. This locking system for intermediate mechanical parts, glued or at least linked to the glazing, allows the glazing to be fixed in its plane in a very simple. According to a first variant, the frame has a frame fitted with at least a groove and then, the deformable element is a tab which is inserted in the groove. The other variant, in which the frame has a fitted frame at least one rib and where the deformable element is a tab which, in position blocking, encloses said rib works exactly according to the same principle. Advantageously, the intermediate mechanical part has a dimension adjustable in the direction of the glazing plane. To make this adjustment, we suggest that the mechanical part comprises two prismatic parts comprising each an inclined plane in contact with that of the other party, and that the moving from one inclined plane to the other changes the dimension of the mechanical part in the plane of the glazing. To avoid any adjustment, the invention provides that the inclined planes have steps whose shape is such that the displacement of a plane in contact with the other authorizes only the increase the dimension of the mechanical part in the plane of the glazing.

On voit qu'ainsi l'invention résout parfaitement le problème technique posé.We see that thus the invention perfectly solves the technical problem posed.

La figure 1 représente un cadre de fenêtre traditionnel, en bois dans lequel est installé un vitrage double. On voit en 1 le cadre support qui a une section en L, en 2 le vitrage isolant avec ses vitres 3. Le vitrage est posé sur la partie horizontale du L, en général par l'intermédiaire de cales non représentées. Il est maintenu latéralement d'une part par la partie verticale du L et d'autre part, par une pareclose 7 fixée rigidement à la partie horizontale du L. Le vitrage isolant est réalisé à l'aide de deux éléments, d'une part un cadre intercalaire rigide, notamment métallique 5 rempli de desséchant dont la fonction est de maintenir écartées les deux vitres et d'autre part, une colle 6 qui assure à la fois la tenue mécanique et l'étanchéité à l'eau liquide. Figure 1 shows a traditional wooden window frame in which double glazing is installed. We see in 1 the support frame which has an L-shaped section, in 2 the insulating glazing with its panes 3. The glazing is placed on the horizontal part of the L, generally by means of shims not shown. It is held laterally on the one hand by the vertical part of the L and on the other hand, by a glazing bead 7 rigidly fixed to the horizontal part of the L. The insulating glazing is produced using two elements, on the one hand a rigid intermediate frame, in particular a metallic 5 filled with desiccant, the function of which is to keep the two panes apart and, on the other hand, an adhesive 6 which ensures both the mechanical strength and the tightness with liquid water.

Pour réaliser l'étanchéité entre l'intérieur et l'extérieur du local, on voit en 4 un mastic qui empêche la pénétration de l'eau. En général, le cadre métallique 5 est séparé des surfaces internes des vitres par l'interposition d'un joint butyl qui participe également, avec le joint en élastomère 6, à l'étanchéité du vitrage isolant.To seal between the inside and outside of the room, we see in 4 a putty which prevents the penetration of water. In general, the metal frame 5 is separated from the internal surfaces of the windows by the interposition of a butyl seal which also participates, with the elastomer seal 6, for sealing the insulating glazing.

La figure 2 montre la coupe d'une variante d'un panneau vitré selon l'invention. On voit cette fois-ci que l'intercalaire métallique du vitrage isolant a été reportée vers l'intérieur du vitrage. Le décalage est de l'ordre de quelques millimètres, compris en général entre 2 et 6 mm. Sur la figure, l'élément de cadre 8 selon l'invention comporte en 9 une baguette intégrée qui pénètre entre les deux vitres du vitrage isolant. Elle constitue avec l'élément de cadre 8 un ensemble structurellement lié. La fonction première de cette baguette 9 est d'assurer la liaison mécanique latérale entre le vitrage isolant et l'élément de cadre 8. Pour exercer cette fonction, il n'est pas nécessaire que la baguette 9 soit continue, elle peut être interrompue en certains endroits. Entre les faces latérales de la baguette 9 et les surfaces internes des vitres 3 on prévoit, lorsque la baguette est continue, un ou deux systèmes d'étanchéité, soit avec des systèmes élastomères qui sont pressés entre les deux surfaces, soit avec des systèmes de mastic qui restent plastiques, du type butyl, et qui adhèrent aux surfaces. Lorsque la baguette 9 est discontinue, un système d'étanchéité indépendant est prévu, il s'agit par exemple d'une baguette analogue à la baguette 7 de la figure 1 mais qui, à la différence de celle-ci, ne joue aucun rôle de maintien latéral du vitrage isolant. Il s'agit simplement d'assurer le maintien du mastic 4 en place et son épaisseur est réduite à un minimum. Figure 2 shows the section of a variant of a glazed panel according to the invention. It is seen this time that the metallic interlayer of the insulating glazing has been transferred towards the interior of the glazing. The offset is of the order of a few millimeters, generally between 2 and 6 mm. In the figure, the frame element 8 according to the invention comprises at 9 an integrated strip which penetrates between the two panes of the insulating glazing. It constitutes with the frame element 8 a structurally linked whole. The primary function of this strip 9 is to provide the lateral mechanical connection between the insulating glazing and the frame element 8. To exercise this function, the strip 9 need not be continuous, it can be interrupted by certain places. Between the lateral faces of the strip 9 and the internal surfaces of the panes 3, one or two sealing systems are provided, when the strip is continuous, either with elastomer systems which are pressed between the two surfaces, or with sealing systems. putty which remain plastic, of the butyl type, and which adhere to surfaces. When the strip 9 is discontinuous, an independent sealing system is provided, it is for example a strip similar to the strip 7 of Figure 1 but which, unlike the latter, plays no role lateral support of insulating glass. It is simply a matter of keeping the sealant 4 in place and its thickness is reduced to a minimum.

En partie basse de l'élément de cadre 8 qui est ici représenté droit, se trouvent habituellement les systèmes qui permettent de rendre étanche la liaison entre l'élément de cadre 8 et le dormant s'il s'agit d'un panneau vitré ouvrant ou entre le panneau vitré et la structure qui l'encadre lorsqu'il s'agit d'un élément fixe. L'homme du métier connaít ces systèmes et sait les réaliser.In the lower part of the frame element 8 which is shown here straight, are usually the systems which make it possible to seal the connection between the element of frame 8 and the frame if it is a glass panel opening or between the glass panel and the structure that frames it when it is a fixed element. Those skilled in the art know these systems and knows how to realize them.

Avec le dispositif représenté figure 2 on doit construire le châssis autour du vitrage, c'est-à-dire que dans le cas d'un vitrage rectangulaire, on va équiper les quatre côtés du vitrage d'éléments de cadre analogues à l'élément 8, ces éléments de cadre ont été préparés à leurs extrémités avec des systèmes d'assemblage d'angle par exemple du type tenon et mortaise, dans le cas du bois, de manière à pouvoir être assemblés dans les angles après avoir été posés à la périphérie du vitrage.With the device shown in Figure 2 we must build the frame around the glazing, that is to say that in the case of a rectangular glazing, we will equip the four sides of the glazing with frame elements similar to the element 8, these frame elements have been prepared at their ends with corner joining systems, for example of the tenon and mortise type, in the case of wood, so that they can be assembled in the corners after having been laid at the periphery of the glazing.

En revanche, le système représenté figure 3 se rapproche beaucoup plus des systèmes de montage de vitrages isolants traditionnels. Ici, l'élément de cadre est en deux parties : d'une part, un élément de cadre proprement dit 11, et d'autre part une baguette séparée 12. Il est possible de procéder à l'assemblage des éléments analogues à l'élément 11 qui constitueront un châssis, semblable aux châssis traditionnels, dans l'atelier de menuiserie, et c'est seulement au moment de la pose du vitrage dans ce cadre que les baguettes 12 vont être introduites puis finalement fixées aux éléments de cadre 11 à l'aide de fixations telles que des vis 13.On the other hand, the system shown in FIG. 3 is much closer to the systems for mounting traditional insulating glazing. Here, the frame element is in two parts: on the one hand, an actual frame element 11, and on the other hand a separate rod 12. It is possible to assemble elements similar to the element 11 which will constitute a frame, similar to traditional frames, in the carpentry workshop, and it is only at the time of the installation of the glazing in this frame that the strips 12 will be introduced then finally fixed to the frame elements 11 to using fasteners such as screws 13.

Dans le cas d'un vitrage rectangulaire, lorsque les quatre baguettes ont été introduites dans les logements prévus à la périphérie du vitrage, on peut introduire l'ensemble du vitrage équipé de ses quatre baguettes à l'intérieur du cadre constitué par les éléments de cadre 11 assemblés dans les coins. Cette technique de montage est ainsi peu différente de la technique habituelle schématisée figure 1.In the case of a rectangular glazing, when the four rods have been introduced into the housings provided at the periphery of the glazing, it is possible to introduce the whole of the glazing equipped with its four rods inside the frame formed by the elements of frame 11 assembled in the corners. This mounting technique is thus little different from the usual technique shown schematically in Figure 1 .

Dans le cadre de l'invention, on peut utiliser comme matériaux pour réaliser l'élément de cadre et les baguettes, des matériaux habituellement utilisés pour réaliser des encadrements de fenêtre, tels que le bois, le plastique, le métal et spécialement l'aluminium ou tout autre matériau qui peut remplir cette fonction. Within the framework of the invention, it is possible to use as materials for making the frame element and the rods, materials usually used to make window frames, such as wood, plastic, metal and especially aluminum or any other material which can fulfill this function.

Dans une variante de l'invention non représentée, l'élément de cadre et sa baguette faits de préférence en une seule pièce, sont constitués d'un matériau susceptible de constituer le cadre intercalaire 5 de la figure 2. Dans ce cas, c'est la baguette elle-même introduite à la périphérie du double vitrage qui constitue le cadre intercalaire du vitrage isolant si bien que dans ce cas les étanchéités du vitrage isolant, c'est-à-dire celles entre les vitres et le cadre intercalaire d'une part et les étanchéité du vantail de la fenêtre entre le vitrage et son châssis de l'autre, seront réalisées en une seule opération.In a variant of the invention not shown, the frame element and its rod, preferably made in one piece, are made of a material capable of constituting the intermediate frame 5 of FIG . 2 . In this case, it is the rod itself introduced at the periphery of the double glazing which constitutes the intermediate frame of the insulating glazing so that in this case the seals of the insulating glazing, that is to say those between the panes and the intermediate frame on the one hand and the sealing of the window sash between the glazing and its frame on the other, will be carried out in a single operation.

La description à laquelle on vient de procéder a été faite avec un vitrage isolant constitué de deux vitres, un double vitrage. L'invention n'est pas limitée à deux vitres mais elle concerne également tout vitrage multiple. Il suffit pour être dans le cadre de cette première variante de l'invention qu'une baguette soit introduite entre au moins deux vitres du vitrage isolant multiple.The description which we have just proceeded has been made with insulating glazing consisting of two panes, double glazing. The invention is not limited to two panes but it also relates to any multiple glazing. It is enough to be under this first variant of the invention that a strip is inserted between at least two panes multiple insulating glass.

Sur la figure 4 on a représenté une variante du système de l'invention. On voit en 14 un élément de cadre d'une forme particulière dont il sera question plus loin, en 15, la baguette située entre les deux verres du vitrage isolant et en 16 la fixation qui les relie l'un à l'autre. Le vitrage isolant est constitué de deux vitres associées à l'aide d'un cadre intercalaire 17 qui est relié aux vitres par l'intermédiaire d'un joint butyl 19 tandis qu'en 18 on voit un élastomère tel que par exemple un polysulfure qui constitue le joint mécanique reliant les vitres du vitrage isolant et le cadre intercalaire. On voit également en 21 des joints en élastomère qui assurent l'étanchéité entre l'élément de cadre et le vitrage. Le vitrage de la figure 4, à la différence des vitrages précédents, est dissymétrique, c'est-à-dire que l'un des verres est de dimension plus grande que l'autre et vient s'insérer ainsi dans la partie prévue sur l'élément de cadre, dissymétrique ici. FIG. 4 shows a variant of the system of the invention. We see in 14 a frame element of a particular shape which will be discussed later, in 15, the strip located between the two glasses of the insulating glazing and in 16 the fixing which connects them to each other. The insulating glazing consists of two panes associated with the aid of an intermediate frame 17 which is connected to the panes by means of a butyl seal 19 while at 18 we see an elastomer such as for example a polysulphide which constitutes the mechanical seal connecting the insulating glass panes and the intermediate frame. We also see at 21 elastomer seals which seal between the frame element and the glazing. The glazing in Figure 4 , unlike the previous glazing, is asymmetrical, that is to say that one of the glasses is larger than the other and thus fits into the part provided on the frame element, asymmetrical here.

Sur la figure 4, la vitre 20 ne s'étend pas jusqu'à la périphérie de l'élément de cadre 14. En réalité, il est également possible dans le cadre de l'invention d'avoir une vitre 20 qui recouvre complètement le cadre 14.In FIG. 4 , the window 20 does not extend to the periphery of the frame element 14. In reality, it is also possible within the scope of the invention to have a window 20 which completely covers the frame 14.

L'avantage d'une disposition où la vitre extérieure recouvre partiellement ou totalement le châssis est qu'elle assure une protection complète du cadre de la paroi vitrée. Non seulement la protection est assurée mais également l'étanchéité à l'eau liquide, à la pluie en particulier, est améliorée lorsque le vitrage 20 de plus grande dimension est situé du côté extérieur de la paroi vitrée. Il est également possible de réaliser grâce à cette disposition un effet esthétique tout à fait particulier. Il est même possible d'imaginer une vitre 20 qui ait des dimensions supérieures à celles du cadre 14 de manière à venir recouvrir non seulement la partie ouvrante d'une fenêtre mais également son dormant (cas d'une ouverture du vantail vers l'extérieur).The advantage of a layout where the exterior glass partially covers or totally the frame is that it provides complete protection of the frame of the glass wall. Protection is not only guaranteed, but also watertightness, rain in particular is improved when the glazing 20 of larger dimension is located on the outside of the glass wall. It is also possible to achieve thanks to this arrangement a very particular aesthetic effect. It is even possible to imagine a window 20 which has dimensions greater than those of frame 14 so as to come cover not only the opening part of a window but also its window frame (case leaf opening to the outside).

Dans tous les systèmes de l'invention que l'on vient de décrire, il est souvent préféré que les vitres soient équipées à leur périphérie d'un cadre décoratif, de préférence situé sur la face intérieure de la vitre et constitué d'un émail, en particulier d'un émail cuit à chaud qui permet de cacher à la vue les éléments du vitrage isolant et de l'ouvrant et de l'élément de cadre qui sont situés à l'intérieur du vitrage isolant. Cet encadrement peut être coloré et constitue à son tour un élément de décor.In all the systems of the invention which have just been described, it is often preferred that the panes be fitted at their periphery with a decorative frame, preferably located on the inside of the glass and made of enamel, in particular baked enamel hot which hides the elements of the insulating glazing and the opening and the frame element which are located inside the insulating glazing. This framework can be colored and in turn constitutes a decorative element.

La variante de l'invention que l'on vient de décrire permet la réalisation de fenêtres extrêmement légères dans lesquelles l'encadrement du vantail ouvrant ne possède que les dimensions minimum nécessaires qui permettent ainsi d'éviter des cadres très épais qui sont habituellement indispensables, en particulier lorsqu'on utilise des vitrages isolants avec un espace d'air intérieur de 12 mm ou plus.The variant of the invention which has just been described allows the production of windows extremely light in which the frame of the opening leaf has only the minimum dimensions necessary, thus avoiding very thick frames which are usually essential, especially when using insulating glass with an interior air space of 12 mm or more.

Les figures 5 à 8 concernent une deuxième variante de l'invention dans laquelle on vient poser un vitrage isolant traditionnel dans le cadre d'un vantail de fenêtre. Figures 5 to 8 relate to a second variant of the invention in which a traditional insulating glazing unit is placed in the context of a window sash.

Sur la figure 5, on voit en 31 une pièce mécanique intermédiaire selon l'invention. Il s'agit ici d'une pièce adaptée d'une part à un vitrage isolant double et d'autre part à une huisserie comportant une rainure longitudinale comme par exemple un châssis de fenêtre en bois.In Figure 5 , we see at 31 an intermediate mechanical part according to the invention. This is a part adapted on the one hand to double insulating glazing and on the other hand to a frame having a longitudinal groove such as for example a wooden window frame.

La pièce de liaison 31 est destinée à être collée sur le vitrage double. Celui-ci est du type collé, en particulier avec un cadre intercalaire métallique, mais les vitrages isolants à intercalaire plastique du type butyl sont parfaitement compatibles avec l'invention. On verra plus loin que l'invention procure même un avantage supplémentaire dans le cas de tels vitrages.The connecting piece 31 is intended to be glued to the double glazing. This one is from glued type, in particular with a metallic interlayer frame, but insulating glazing with plastic interlayer of the butyl type are perfectly compatible with the invention. We will see later that the invention even provides an additional advantage in the case of such glazing.

La pièce de liaison 31 est en matière plastique rigide, notamment matière adaptée à l'injection comme par exemple en polyamide.The connecting piece 31 is made of rigid plastic, in particular material suitable for injection, such as polyamide.

La partie supérieure extérieure 32, de part et d'autre de la pièce 31 sert de support aux plaques de verre. La nervure centrale 33 et son embase 34 sont toutes deux noyées dans la colle du vitrage isolant. En effet, la liaison entre la pièce 31 et le vitrage isolant se fait de préférence au moment de la fabrication de ce dernier, juste après le dépôt de la colle extérieure (en général du polysulfure ou exceptionnellement, du silicone). De cette manière, c'est la colle du vitrage isolant elle-même qui assure la fixation par collage de la pièce mécanique . Des pièces de liaison telles que celles de la figure 5 sont posées de place en place sur les quatre côtés du vitrage isolant. La largeur des pièces de liaison 31 dans le plan du vitrage est telle qu'elle permette au vitrage d'être relié sans contrainte aux quatre côtés du châssis.The outer upper part 32, on either side of the part 31 serves as a support for the glass plates. The central rib 33 and its base 34 are both embedded in the glue of the insulating glazing. Indeed, the connection between the part 31 and the insulating glazing is preferably made at the time of manufacture of the latter, just after the deposition of the external adhesive (generally polysulfide or, exceptionally, silicone). In this way, it is the glue of the insulating glazing itself which ensures the fixing by gluing of the mechanical part. Connection pieces such as those of FIG. 5 are placed from place to place on the four sides of the insulating glazing. The width of the connecting pieces 31 in the plane of the glazing is such that it allows the glazing to be connected without constraint to the four sides of the frame.

La nervure centrale 33 est équipée de dents longitudinales qui accroissent la surface de collage et améliorent l'accrochage de la pièce au vitrage.The central rib 33 is equipped with longitudinal teeth which increase the surface bonding and improve the attachment of the part to the glazing.

La nervure 33 et son embase 34 constitue un organe en ressaut qui, en plus de faciliter l'adhérence vitrage-pièce de liaison joue un rôle important de transmission des efforts latéraux entre le vitrage et le châssis. Une fois le vitrage avec ses pièces de liaison 31 posé dans la baie et la baie dans la façade du bâtiment, c'est non seulement le collage de l'organe en ressaut dans le vitrage mais ce sont aussi les bords de l'embase 34 voisins des plaques de verre qui permettront de transmettre les efforts comme ceux du vent, du vitrage au châssis. Les emplacements des pièces de liaison 31 à la périphérie du vitrage sont choisis par le spécialiste de la pose des vitrages isolants en fonction de ses connaissances de la résistance des matériaux et de la réglementation. D'autre part, dans le cas où le vitrage isolant ne possède pas d'intercalaire métallique mais simplement un cordon de butyl, les pièces de liaison 31 permettent, grâce à leur ressaut 40 sur lequel s'appuient les vitres, de garantir l'uniformité et la stabilité de l'épaisseur du vitrage.The rib 33 and its base 34 constitutes a projecting member which, in addition to facilitating the adhesion between glazing and connecting piece plays an important role in transmitting lateral forces between the glazing and the frame. Once the glazing with its connecting parts 31 posed in the bay and the bay in the facade of the building, it is not only the collage of the member projects into the glazing, but these are also the edges of the base 34 neighboring the glass plates which will transmit forces such as wind, glazing to the chassis. The locations of the connecting pieces 31 at the periphery of the glazing are chosen by the specialist in the installation of insulating glass according to his knowledge resistance of materials and regulations. On the other hand, in the event that the insulating glass does not have a metal interlayer but simply a cord of butyl, the connecting pieces 31 allow, thanks to their projection 40 on which the panes, to guarantee the uniformity and stability of the glazing thickness.

A la différence de ce qui était connu, et de ce qui est pratiqué avec les baguettes rapportées 12 de la figure 3 qui sont vissées dans le cadre, les pièces de liaison de l'invention ne sont pas fixées dans la baie par vissage mais elles sont immobilisées latéralement grâce à des éléments déformables tels que des pattes ou taquets qui viennent s'encliqueter soit dans des logements creux, soit sur des reliefs.Unlike what was known, and what is practiced with the attached rods 12 of Figure 3 which are screwed into the frame, the connecting pieces of the invention are not fixed in the bay by screwing but they are immobilized laterally thanks to deformable elements such as lugs or cleats which snap either in hollow housings or on reliefs.

Sur la figure 5 des taquets 35 sont prévus aux extrémités de la pièce de liaison 31. De préférence, ces taquets 35 sont faits de la même matière que la pièce 31 et ils lui sont liés par une languette 36 qui permet de faire effectuer au taquet une rotation dans le sens de la flèche 37 mais qui, une fois que le taquet a pris une position perpendiculaire à la base de la pièce 31, assure, sans se rompre ni se déformer, une transmission complète des efforts latéraux.In FIG. 5, cleats 35 are provided at the ends of the connecting piece 31. Preferably, these cleats 35 are made of the same material as the piece 31 and they are connected to it by a tongue 36 which allows the cleat to be made a rotation in the direction of arrow 37 but which, once the cleat has taken a position perpendicular to the base of the part 31, ensures, without breaking or deforming, a complete transmission of the lateral forces.

Dans sa position perpendiculaire à la base de la pièce 31, le taquet 35 pénètre et s'ajuste dans une rainure prévue dans la feuillure du châssis.In its position perpendicular to the base of the part 31, the cleat 35 penetrates and fits in a groove provided in the rebate of the chassis.

Sur la figure 6, on voit un exemple de mise en oeuvre du système de fixation de vitrage de l'invention. La mise en oeuvre est ici plus traditionnelle que dans la première variante de l'invention, objet des figures 2 à 4, en effet, le dormant 43 et la partie extérieure de l'ouvrant 42 sont tout à fait analogues à ce qui est schématisé figure 1. Mais ici, le vitrage 39 repose sur la pièce de liaison 31 dont le ressaut 40 pénètre entre les deux plaques de verre et y adhère. La patte 35 est logée dans la rainure 38.In Figure 6 , we see an example of implementation of the glazing fixing system of the invention. The implementation is here more traditional than in the first variant of the invention, the object of Figures 2 to 4 , in fact, the frame 43 and the outer part of the opening 42 are completely similar to what is shown schematically figure 1 . But here, the glazing 39 rests on the connecting piece 31 whose projection 40 penetrates between the two glass plates and adheres thereto. The tab 35 is housed in the groove 38.

Sur la figure 5 on voit deux crochets 41 dont la fonction est de bloquer le taquet 35 une fois qu'il est logé dans la rainure 38. Ce blocage des éléments déformables tels que les taquets 35 garantit que dès que le vitrage est en position dans son châssis, il ne bougera plus. Il garantit également l'inviolabilité de la fermeture du local par le vitrage. Même si un voleur réussissait à accéder aux pièces de liaison 31, l'ouverture de tous les crochets tels que 11, si elle est théoriquement possible, demanderait beaucoup de temps. En revanche, pour l'homme du métier de la fenêtre qui connaít le système de l'invention et qui dispose de temps, l'échange du vitrage est aisé, il suffit, comme on le voit figure 6, après avoir enlevé le cache de protection enjoliveur 44, de couper depuis l'intérieur du local tous les éléments déformables 35 pour pouvoir extraire le vitrage 39 du cadre. Une telle opération n'est pas faisable de l'extérieur.In Figure 5 we see two hooks 41 whose function is to block the cleat 35 once it is housed in the groove 38. This blocking of the deformable elements such as the cleats 35 ensures that as soon as the glazing is in position in its chassis, it will not move. It also guarantees the inviolability of the closing of the room by the glazing. Even if a thief managed to gain access to the connecting pieces 31, the opening of all the hooks such as 11, if it is theoretically possible, would take a long time. On the other hand, for the person skilled in the art of the window who knows the system of the invention and who has time, the exchange of the glazing is easy, it suffices, as can be seen in FIG. 6 , after removing the cover from hubcap protection 44, to cut from the interior of the room all the deformable elements 35 in order to be able to extract the glazing 39 from the frame. Such an operation is not feasible from the outside.

Toujours sur la figure 6, on voit que vue de l'extérieur, l'huisserie avec son ouvrant 42 et son dormant 43, offre un aspect traditionnel. Le système de fixation de vitrage de l'invention a simplement permis de supprimer la pareclose intérieure. Comme il n'est plus besoin de supporter le vitrage latéralement, il a été possible d'amincir sensiblement l'élément de cadre, en l'occurrence la traverse basse 42 et de remplacer la pareclose par un enjoliveur 44 dont la seule fonction technique est d'assurer l'étanchéité vitrage-huisserie grâce au joint butyl 45. L'amincissement des éléments du cadre de l'ouvrant est le même sur les montants et sur la traverse haute que sur la traverse basse et les techniques de mise en oeuvre sont également les mêmes.Still in FIG. 6 , it can be seen that seen from the outside, the frame with its opening 42 and its frame 43, offers a traditional appearance. The glazing fixing system of the invention simply made it possible to eliminate the interior glazing bead. As there is no longer any need to support the glazing laterally, it has been possible to appreciably thin the frame element, in this case the bottom cross member 42 and to replace the glazing bead with an embellisher 44 whose only technical function is to ensure the glazing-frame tightness thanks to the butyl seal 45. The thinning of the elements of the frame of the opening is the same on the uprights and on the upper cross member as on the lower cross member and the implementation techniques are also the same.

Sur la figure 6 on a supprimé une pareclose, du côté intérieur mais une étude nouvelle complète de la fenêtre permettra également d'amincir le profilé de l'autre côté, à l'extérieur. Cela est d'autant plus aisé qu'à l'extérieur, les problèmes d'étanchéité sont plus simples dans le cas de feuillures drainantes comme ici. Le fait d'avoir choisi une largeur de la pièce de liaison 1 qui soit au maximum égale à l'épaisseur du vitrage permet de diminuer l'épaisseur de l'huisserie jusqu'à cette largeur si la chose est possible compte-tenu des autres exigences liées à l'étanchéité, à la tenue mécanique de l'ouvrant en position d'ouverture, à l'esthétique, etc...In Figure 6 we have deleted a glazing bead on the inside but a new complete study of the window will also make it possible to thin the profile on the other side, outside. This is all the easier since outside, the sealing problems are simpler in the case of draining rebates as here. The fact of having chosen a width of the connecting piece 1 which is at most equal to the thickness of the glazing makes it possible to reduce the thickness of the frame up to this width if this is possible taking into account the others requirements related to sealing, mechanical strength of the opening in the open position, aesthetics, etc.

La figure 7 et la figure 8 présentent chacune une partie d'une pièce de liaison dont la dimension dans le plan du vitrage est réglable. Chaque partie a la forme d'un prisme à section triangulaire et le déplacement des deux rampes inclinées l'une par rapport à l'autre permet d'ajuster l'épaisseur. Les rampes inclinées comportent en plus, des gradins avec un côté incliné et l'autre droit. Les gradins sont inclinés de telle manière qu'il est facile de faire glisser une rampe sur l'autre lorsqu'on veut accroítre l'épaisseur de la pièce de liaison. Le mouvement dans l'autre direction ne serait possible qu'après avoir écarté les rampes l'une de l'autre. Figure 7 and Figure 8 each show a part of a connecting piece whose dimension in the plane of the glazing is adjustable. Each part has the shape of a triangular section prism and the displacement of the two ramps inclined with respect to each other allows the thickness to be adjusted. The inclined ramps also have steps with one inclined side and the other straight. The steps are inclined so that it is easy to slide one ramp over the other when you want to increase the thickness of the connecting piece. Movement in the other direction would only be possible after moving the ramps apart.

Sur la figure 7 on voit le vitrage 39 avec ses plaques de verre 48, 49 qui reposent sur les parties supérieures 32 de la moitié 50 de la pièce de liaison qui est collée au vitrage. Cette moitié 50 comporte des guides 51. Leur fonction est temporaire, elle ne joue qu'au moment du collage de la moitié 50 sur le vitrage, ils permettent de maintenir la pièce en place en attendant la prise de la colle, en effet, ils exercent une certaine pression sur les faces du vitrage ce qui centre la pièce et la maintient immobile le temps nécessaire.In Figure 7 we see the glazing 39 with its glass plates 48, 49 which rest on the upper parts 32 of the half 50 of the connecting piece which is glued to the glazing. This half 50 has guides 51. Their function is temporary, it only plays when the half 50 is glued to the glazing, they make it possible to hold the part in place while waiting for the glue to set, in fact, they exert a certain pressure on the faces of the glazing which centers the part and keeps it stationary for the necessary time.

Sur la figure 8 l'autre moitié 52 est représentée avec ses gradins 47 en relief (les gradins 46 de la moitié 51 sont, eux, en creux, et ainsi, tout déplacement latéral d'une moitié par rapport à l'autre est impossible). La moitié 52 possède bien entendu des organes déformables sous la forme ici également de pattes 35 attachées par une languette 36 au corps de la moitié 52.In Figure 8 the other half 52 is shown with its steps 47 in relief (the steps 46 of the half 51 are, them, hollow, and thus, any lateral movement of one half relative to the other is impossible ). The half 52 of course has deformable members here also in the form of lugs 35 attached by a tongue 36 to the body of the half 52.

L'installation de la pièce de liaison en deux parties 50, 52 peut se faire de la manière suivante : le vitrage étant équipé du nombre de moitiés 50 voulu, par exemple deux par côté pour un vitrage de 50 x 80 cm, est présenté horizontalement au dessus du châssis 42 (figure 6) placé sur une table, avec la feuillure en dessous. Des cales temporaires placées sous le vitrage permettent de le situer de manière symétrique par rapport à la rainure 38. Le vitrage 39 est centré dans la baie avec par conséquent toutes les moitiés 50 de pièce de liaison à la même distance de la feuillure. Les moitiés 52 sont alors mises en place sans les serrer et les taquets 35 à leurs extrémités sont insérés dans les rainures 38. Pour finir, le serrage des pièces de liaison est terminé et le vantail redressé.The installation of the connecting part in two parts 50, 52 can be done as follows: the glazing being equipped with the desired number of halves 50, for example two per side for a glazing of 50 x 80 cm, is presented horizontally above the frame 42 ( Figure 6 ) placed on a table, with the rebate below. Temporary shims placed under the glazing make it possible to locate it symmetrically with respect to the groove 38. The glazing 39 is centered in the opening with consequently all the halves 50 of connecting piece at the same distance from the rebate. The halves 52 are then put in place without tightening them and the tabs 35 at their ends are inserted into the grooves 38. Finally, the tightening of the connecting pieces is finished and the leaf straightened.

La technique de pose qui vient d'être décrite et qui est adaptée aux vantaux des fenêtres dites « à la française » de dimension moyenne, dans lesquelles le vitrage est installé dans l'huisserie sur le lieu de fabrication de cette dernière, est une possibilité parmi d'autres. Pour les grands vitrages, la pose se fait, vitrage vertical.The installation technique which has just been described and which is adapted to the leaves of the so-called “French-style” windows of medium size, in which the glazing is installed in the frame at the place of manufacture of the latter, is a possibility among others. For large glazing, installation is done, vertical glazing.

La figure 9 montre une variante dans laquelle, l'huisserie ne comporte pas de rainure mais au contraire, des nervures en relief sur lesquelles reposent les pièces mécaniques de liaison. FIG. 9 shows a variant in which the frame does not have a groove but on the contrary, raised ribs on which the mechanical connecting parts rest.

On voit sur la figure en 53 une partie de l'huisserie en aluminium avec ses nervures 54, 55. La pièce de liaison 56 comporte un taquet 57 de forme adaptée et qui comporte donc deux échancrures 58, 59 destinées à enserrer les nervures 54, 55. Le système de verrouillage est identique à celui des figures 5 et 8 mais tout système équivalent convient.We see in the figure at 53 a part of the aluminum frame with its ribs 54, 55. The connecting piece 56 comprises a cleat 57 of suitable shape and which therefore comprises two notches 58, 59 intended to enclose the ribs 54, 55. The locking system is identical to that of FIGS. 5 and 8, but any equivalent system is suitable.

Le système de fixation d'un vitrage dans une baie qu'on vient de décrire dans cette deuxième variante de l'invention, outre qu'il est particulièrement simple à mettre en oeuvre, présente l'avantage d'être réglable. Son utilisation permet, comme celle de la première variante, de réduire les épaisseurs des huisseries à ce qui est strictement nécessaire d'un point de vue mécanique, toutes les questions liées à la fixation du vitrage dans son huisserie étant résolues par le système de l'invention.The system for fixing a glazing in a bay that has just been described in this second variant of the invention, in addition to being particularly simple to implement work, has the advantage of being adjustable. Its use allows, like that of the first variant, to reduce the thickness of the frames to what is strictly mechanically necessary, all questions related to fixing the glazing in its frame being solved by the system of the invention.
