Description

VITRAGE ISOLANT AVEC ESPACEUR AMELIORE INSULATING GLASS WITH IMPROVED SPACER
L'invention concerne le domaine des vitrages isolants double ou triple comportant au moins deux feuilles de verre espacées par au moins une lame d'air ou de gaz à l'aide d'au moins un espaceur agencé à la périphérie des feuilles de verre. La présente invention concerne des vitrages avec de nouvelles formes d'espaceur. The invention relates to the field of double or triple insulating glazing comprising at least two sheets of glass spaced apart by at least one layer of air or gas using at least one spacer arranged at the periphery of the sheets of glass. The present invention relates to glazing with new forms of spacer.
Le document WO2017/157634 (ou EP 3 430 225 Al), au nom du demandeur, propose de fabriquer des vitrages isolants avec des espaceurs transparents, au niveau de leurs côtés verticaux. Les espaceurs sont fixés avec des adhésifs transparents, l'adhésif étant en interface entre l'espaceur et la face interne des verres du vitrage. Document WO2017/157634 (or EP 3 430 225 A1), in the name of the applicant, proposes manufacturing insulating glazing units with transparent spacers, at their vertical sides. The spacers are fixed with transparent adhesives, the adhesive being at the interface between the spacer and the internal face of the panes of the glazing.
La présente invention a pour but de proposer de nouvelles formes d'espaceur permettant une bonne adhésion de l'espaceur aux feuilles de verre. The object of the present invention is to propose new forms of spacer allowing good adhesion of the spacer to the sheets of glass.
L'invention vise également à améliorer l'étanchéité des vitrages doubles ou triples, notamment l'étanchéité aux gaz et à la vapeur d'eau. The invention also aims to improve the tightness of double or triple glazing, in particular gas and water vapor tightness.
L'invention peut s'appliquer aux espaceurs transparents ainsi que non transparents. The invention can be applied to transparent as well as non-transparent spacers.
L'invention vise également à fournir un vitrage qui évite les défauts de type dendrite. Ces défauts, qui apparaissent notamment lorsque le vitrage est soumis à des gradients importants de température, s'opposent non seulement à l'obtention d'un vitrage présentant de bonnes caractéristiques esthétiques, mais peuvent également être la source de problèmes d'étanchéité du vitrage. The invention also aims to provide a glazing which avoids defects of the dendrite type. These defects, which appear in particular when the glazing is subjected to significant temperature gradients, not only prevent the obtaining of a glazing having good aesthetic characteristics, but can also be the source of problems of sealing of the glazing. .
La présente invention a pour objet un vitrage isolant double ou triple comportant : The subject of the present invention is a double or triple insulating glazing comprising:
- au moins deux feuilles de verre comportant quatre côtés, espacées par au moins une lame d'air ou de gaz, - at least two sheets of glass with four sides, spaced apart by at least one air or gas layer,
- au moins un espaceur agencé à la périphérie des feuilles de verre, le long des quatre côtés et maintenant espacées les deux feuilles de verre, ledit espaceur comportant deux faces longitudinales de fixation sensiblement parallèles, ainsi qu'une face interne tournée vers la lame d'air ou de gaz et une face externe, - at least one spacer arranged at the periphery of the glass sheets, along the four sides and maintaining the two glass sheets spaced apart, said spacer comprising two faces substantially parallel longitudinal fastening strips, as well as an internal face facing the air or gas layer and an external face,
- une barrière d'étanchéité assurant l'étanchéité de la lame d'air ou de gaz. - a sealing barrier ensuring the sealing of the air or gas gap.
L'espaceur comporte sur au moins un des côtés du vitrage un élément de rétention permettant d'éviter le fluage de la barrière d'étanchéité vers la lame d'air ou de gaz (face interne de l'espaceur). En outre, que l'espaceur est réalisé dans la même matière sur les quatre côtés du vitrage. The spacer comprises on at least one of the sides of the glazing a retention element making it possible to prevent the sealing barrier from creeping towards the air or gas layer (internal face of the spacer). Furthermore, that the spacer is made of the same material on the four sides of the glazing.
Outre l'aspect esthétique apporté par le fait que l'espaceur s'étend sur les quatre côtés du vitrage, de sorte à créer le champ de vision le plus aéré possible, l'invention se distingue notablement de l'art antérieur en ce que cet espaceur est réalisé dans la même matière sur les quatre côtés du vitrage. Apart from the aesthetic aspect provided by the fact that the spacer extends over the four sides of the glazing, so as to create the most ventilated field of vision possible, the invention is notably distinguished from the prior art in that this spacer is made of the same material on the four sides of the glazing.
En effet, le choix d'une matière unique pour l'espaceur, sur les quatre côtés du vitrage, permet très avantageusement d'homogénéiser le coefficient de dilatation thermique de la barrière d'étanchéité tout autour du vitrage. Il résulte de ces dispositions une minimisation du risque d'apparition de défauts de type dendrites, en particulier lorsque le vitrage est soumis à des gradients importants de température. Indeed, the choice of a single material for the spacer, on the four sides of the glazing, very advantageously makes it possible to standardize the coefficient of thermal expansion of the sealing barrier all around the glazing. The result of these provisions is a minimization of the risk of appearance of defects of the dendrite type, in particular when the glazing is subjected to significant temperature gradients.
Par ailleurs, les caractéristiques selon lesquelles l'espaceur est réalisé dans la même matière sur les quatre côtés du vitrage permettent, en synergie avec la présence dudit au moins un élément de rétention, d'assurer une excellente étanchéité du vitrage. Furthermore, the characteristics according to which the spacer is made of the same material on the four sides of the glazing make it possible, in synergy with the presence of said at least one retention element, to ensure excellent sealing of the glazing.
Selon un mode d'exécution préféré, l'élément de rétention est constitué d'une double lèvre disposée sur chacune des jonctions entre la face interne et les faces longitudinales de fixation de l'espaceur. According to a preferred embodiment, the retention element consists of a double lip arranged on each of the junctions between the internal face and the longitudinal fixing faces of the spacer.
Les lèvres peuvent avoir une forme sensiblement rectangulaire, une forme triangulaire ou une forme arrondie. The lips can have a substantially rectangular shape, a triangular shape or a rounded shape.
La lèvre est avantageusement réalisée d'un seul tenant avec l'espaceur. Selon un autre mode d'exécution de l'invention, l'élément de rétention est constitué d'une rainure ou gorge, disposée sur les faces longitudinales de l'espaceur. L'invention peut aussi couvrir un élément de rétention qui comporte à la fois des lèvres et des rainures. The lip is advantageously made in one piece with the spacer. According to another embodiment of the invention, the retention element consists of a groove or groove, arranged on the longitudinal faces of the spacer. The invention can also cover a retention element which comprises both lips and grooves.
La barrière d'étanchéité peut être réalisée dans divers matériaux connus de la technique. Elle peut aussi avantageusement être réalisée dans un matériau transparent de type butyle, à base de polysobutylène ou une colle transparente étanche (ex. colle UV acrylate, cyanoacrylate etc.) The sealing barrier can be made of various materials known in the art. It can also advantageously be made of a transparent material of the butyl type, based on polysobutylene or a transparent waterproof glue (eg UV glue acrylate, cyanoacrylate etc.)
Le vitrage selon l'invention comporte de préférence un joint structurel, adhésif qui assure la fixation de l'espaceur aux feuilles de verre. Il vient, de préférence, en contact avec la barrière d'étanchéité. The glazing according to the invention preferably comprises an adhesive structural joint which secures the spacer to the sheets of glass. It preferably comes into contact with the sealing barrier.
Selon un mode d'exécution, l'espaceur est en matière plastique transparente, notamment est en copolymère styrène acrylonitrile (SAN), en polyéthylène téréphtalate (PETg), en polyuréthanne (PU), en polyméthylméthacrylate PMMA, en polycarbonate ou en polyméthylpenthène (TPX). According to one embodiment, the spacer is made of transparent plastic material, in particular is made of styrene acrylonitrile copolymer (SAN), polyethylene terephthalate (PETg), polyurethane (PU), polymethylmethacrylate PMMA, polycarbonate or polymethylpenthene (TPX ).
Selon un mode de réalisation particulier, l'espaceur comporte un chanfrein à la jonction entre chaque face longitudinale et la face externe, de manière à faciliter la pénétration du joint secondaire jusqu'à la barrière d'étanchéité. According to a particular embodiment, the spacer comprises a chamfer at the junction between each longitudinal face and the outer face, so as to facilitate penetration of the secondary seal as far as the sealing barrier.
L'espaceur peut encore comporter, en outre, sur sa face interne, sur au moins un des côtés du vitrage, un film ou revêtement transparent mince d'étanchéité aux gaz et à la vapeur d'eau, en particulier d'une épaisseur d'au plus 500 pm, de préférence comprise en 2 nm et 200 pm. The spacer may further comprise, in addition, on its internal face, on at least one of the sides of the glazing, a thin transparent film or coating for gas and water vapor tightness, in particular with a thickness of at most 500 μm, preferably between 2 nm and 200 μm.
Selon certains modes de réalisation, le vitrage comporte en outre un élément de protection périphérique recouvrant les chants des au moins deux feuilles de verre. According to certain embodiments, the glazing also comprises a peripheral protection element covering the edges of the at least two sheets of glass.
Cet élément de protection périphérique peut être collé sur les chants des au moins deux feuilles de verre, ou éventuellement clipsé sur la face externe de l'espaceur. This peripheral protection element can be glued to the edges of the at least two sheets of glass, or possibly clipped onto the outer face of the spacer.
Le vitrage selon l'invention peut aussi comporter un ou de plusieurs revêtements bas-émissifs et/ou une couche antibuée, antigivre ou anti-reflet. La présente invention est maintenant décrite à l'aide d'exemples uniquement illustratifs et nullement limitatifs de la portée de l'invention, et à partir des illustrations ci-jointes, dans lesquelles : The glazing according to the invention may also comprise one or more low-emissivity coatings and/or an anti-fog, anti-frost or anti-reflection layer. The present invention is now described with the aid of illustrative examples only and in no way limiting the scope of the invention, and from the accompanying illustrations, in which:
La figure 1 est une vue schématique partielle en coupe d'un vitrage selon l'invention ; Figure 1 is a partial schematic sectional view of a glazing according to the invention;
Les figures 2, 3 et 4 sont des vues en coupe schématiques d'un vitrage de l'invention selon des variantes d'espaceur, Figures 2, 3 and 4 are schematic sectional views of a glazing of the invention according to spacer variants,
Les figures 5 et 6 montrent différents espaceurs et les dimensions des éléments de rétention. Les figures ne sont pas à l'échelle pour en faciliter la lecture. Figures 5 and 6 show different spacers and the dimensions of the retention elements. Figures are not to scale for ease of reading.
La figure 1 illustre, en coupe, l'extrémité de deux feuilles de verre 1, 2 maintenues à distance à l'aide d'un espaceur 3 de manière à délimiter une cavité 7 entre les deux feuilles de verre. Comme indiqué aux figures 5 et 6, l'espaceur 3 comporte une face interne 8 dirigée vers la cavité 7, deux faces longitudinales 9, 11, sensiblement parallèles aux feuilles de verre 1, 2, et une face externe 12. FIG. 1 illustrates, in section, the end of two sheets of glass 1, 2 held apart by means of a spacer 3 so as to delimit a cavity 7 between the two sheets of glass. As indicated in Figures 5 and 6, the spacer 3 comprises an internal face 8 directed towards the cavity 7, two longitudinal faces 9, 11, substantially parallel to the glass sheets 1, 2, and an external face 12.
Le vitrage comporte une première barrière d'étanchéité 4 fermant la cavité 7 sur toute la périphérie du vitrage ainsi qu'un second joint structurel 5. The glazing comprises a first sealing barrier 4 closing the cavity 7 over the entire periphery of the glazing as well as a second structural seal 5.
A la fig. 1, un élément de protection périphérique 6 recouvre le joint structurel 5 et les deux chants des feuilles de verre 1, 2. In fig. 1, a peripheral protection element 6 covers the structural seal 5 and the two edges of the glass sheets 1, 2.
L'espaceur 3 présente des éléments de rétention qui permette d'éviter le fluage de la barrière d'étanchéité 4 vers la cavité 7. Dans un premier mode d'exécution (représenté aux figures 1, 2 et 3), l'élément de rétention consiste en des lèvres 13 disposées au niveau la face interne 8 de l'espaceur 3 et qui viennent élargir la face interne 8 par rapport à la distance entre les deux faces longitudinales 9, 11. The spacer 3 has retention elements which make it possible to prevent the flow of the sealing barrier 4 towards the cavity 7. In a first embodiment (represented in FIGS. 1, 2 and 3), the element of retention consists of lips 13 arranged at the level of the internal face 8 of the spacer 3 and which widen the internal face 8 with respect to the distance between the two longitudinal faces 9, 11.
Ces lèvres 13 peuvent avoir une forme carrée (fig 1), triangulaire (fig. 2) ou arrondie (fig. 3).These lips 13 can have a square (fig 1), triangular (fig. 2) or rounded (fig. 3) shape.
La fig. 6 montre les dimensions de la lèvre 13. Elle présente une hauteur « h » comprise entre 0,1 et 10 mm, de préférence entre 0,5 et 5 mm et une largeur « I » généralement comprise entre 0,1 et 5 mm, de préférence entre 0,2 et 1 mm. fig. 6 shows the dimensions of the lip 13. It has a height "h" of between 0.1 and 10 mm, preferably between 0.5 and 5 mm, and a width "I" generally of between 0.1 and 5 mm, preferably between 0.2 and 1 mm.
Dans une variante d'exécution représentée aux fig. 4 et 5, l'élément de rétention évitant le fluage de la barrière d'étanchéité consiste en une gorge 14. La hauteur h de la gorge est généralement comprise entre 0,1 mm et 10 mm, de préférence entre 0,5 mm et 5 mm. Sa profondeur d est généralement comprise entre 0,1 mm et 5mm, de préférence entre 0,2 et 1 mm. La distance p entre la face interne 8 et la gorge est généralement comprise entre 0,1 et 10 mm, de préférence entre 0,5 mm et 10 mm. In a variant embodiment represented in FIGS. 4 and 5, the retention element preventing creep of the sealing barrier consists of a groove 14. The height h of the groove is generally between 0.1 mm and 10 mm, preferably between 0.5 mm and 5mm. Her depth d is generally between 0.1 mm and 5 mm, preferably between 0.2 and 1 mm. The distance p between the inner face 8 and the groove is generally between 0.1 and 10 mm, preferably between 0.5 mm and 10 mm.
Il est aussi possible d'envisager à la fois des lèvres 13 et une gorge 14 sur chaque face longitudinale 9, 11. It is also possible to envisage both lips 13 and a groove 14 on each longitudinal face 9, 11.
Ces différentes formes d'éléments de rétention permettent de faciliter le dépôt de la première barrière d'étanchéité 4 et d'éviter son fluage vers la cavité 7 du vitrage. These different forms of retention elements make it possible to facilitate the deposition of the first sealing barrier 4 and to prevent it from creeping towards the cavity 7 of the glazing.
Le profil de l'espaceur 3 peut être sensiblement carré, comme illustré à la fig. 1 ou avoir des chanfreins au niveau de la face externe 12, comme illustré aux figures 2, 3 et 4. The profile of the spacer 3 can be substantially square, as illustrated in FIG. 1 or have chamfers at the outer face 12, as shown in Figures 2, 3 and 4.
L'invention a donc l'avantage de permettre un large choix de matière pour la barrière d'étanchéité même des matières avec une viscosité inférieure aux matières habituellement utilisées. The invention therefore has the advantage of allowing a wide choice of material for the sealing barrier, even materials with a lower viscosity than the materials usually used.
La présente invention a également un avantage esthétique : dans le cas de vitrages transparents, le fluage de butyle sur la surface visible du verre est évité et, les risques de perte d'étanchéité sont réduits. The present invention also has an aesthetic advantage: in the case of transparent glazing, the creeping of butyl on the visible surface of the glass is avoided and the risks of loss of tightness are reduced.
