Description

ESPACEUR, CONNECTEUR ET VITRAGE ISOLANT  SPACER, CONNECTOR AND INSULATING GLAZING
L'invention concerne un espaceur de vitrage isolant, ou un connecteur en équerre entre deux espaceurs de vitrage isolant, et un vitrage isolant comprenant au moins deux feuilles de verre et au moins un espaceur disposé entre les feuilles de verre. The invention relates to an insulating glazing spacer, or an angled connector between two insulating glazing spacers, and an insulating glazing unit comprising at least two glass sheets and at least one spacer disposed between the glass sheets.
Un espaceur de vitrage isolant est habituellement en métal, par exemple en aluminium ou en acier, ou en matériau composite, par exemple une combinaison de plastique et de métal. Pour réaliser un vitrage isolant, un cordon de butyle est déposé sur les côtés de l'espaceur formant un cadre de forme quelconque, puis le cadre butylé est placé entre deux feuilles de verre. Le cordon de butyle permet à la fois de solidariser l'espaceur aux feuilles de verre afin de réaliser le scellement du vitrage isolant, et de réaliser une première barrière d'étanchéité au gaz et à la vapeur d'eau. Un mastic de polyuréthane, polysulfure ou silicone est ensuite appliqué entre les feuilles de verre du vitrage isolant, à l'extérieur de l'espaceur, entre le bord de l'espaceur orienté vers l'extérieur du vitrage et la tranche des feuilles de verre, ce qui permet de réaliser une deuxième barrière d'étanchéité au gaz et à la vapeur d'eau.  An insulating glazing spacer is usually made of metal, for example aluminum or steel, or composite material, for example a combination of plastic and metal. To make an insulating glass, a butyl bead is deposited on the sides of the spacer forming a frame of any shape, then the butyl frame is placed between two sheets of glass. The butyl bead both makes it possible to secure the spacer to the glass sheets in order to seal the insulating glazing, and to provide a first barrier against gas and water vapor. A polyurethane, polysulfide or silicone sealant is then applied between the glass sheets of the insulating glazing, outside the spacer, between the edge of the spacer facing the outside of the glazing and the edge of the glass sheets. , which makes it possible to produce a second barrier to seal gas and water vapor.
Toutefois, lorsqu'un vitrage isolant est soumis à des charges climatiques ou à des charges de vent, il se déforme. Par exemple, le vitrage se dilate sous l'effet de la chaleur du soleil. Lorsqu'un vitrage isolant muni d'un espaceur tel que décrit ci-dessus se déforme sous l'effet de charges climatiques, le cordon de butyle subit des déformations qui, si elles sont importantes, l'endommagent. Cela détériore l'étanchéité du vitrage isolant, entraînant alors une diminution des per- formances d'isolation thermique du vitrage isolant si de l'air pénètre dans le vitrage isolant et remplace un gaz tel que l'Argon et/ou une diminution de la visibilité si de la vapeur d'eau pénètre entre les feuilles de verre et se condense sur les feuilles de verre à l'intérieur du vitrage isolant.  However, when an insulating glass is subjected to climatic loads or wind loads, it is deformed. For example, the glazing expands under the heat of the sun. When insulating glazing with a spacer as described above deforms under the effect of climatic loads, the butyl bead undergoes deformations which, if they are important, damage it. This deteriorates the sealing of the insulating glazing unit, thereby reducing the thermal insulating performance of the insulating glass if air enters the insulating glass and replaces a gas such as argon and / or a reduction in visibility if water vapor penetrates between the glass sheets and condenses on the glass sheets inside the insulating glass.
Pour éviter ce problème d'endommagement du cordon de butyle, il est connu de dimensionner les vitrages isolants de façon à ne pas excéder un niveau maximum de contrainte mécanique dans les barrières d'étanchéité formées par le mastic et le cordon de butyle. Toutefois, les possibilités de dimensionnement des vitrages isolants sont alors limitées. Ainsi, pour des triple-vitrages de largeur infé- rieure à 800 mm, ou avec des lames de gaz d'épaisseur supérieure à 12 mm ou encore avec des feuilles de verre d'épaisseur supérieure à 6 mm ou du verre feuilleté, les contraintes mécaniques générées dans le cordon de butyle peuvent être élevées, entraînant un endommagement du cordon de butyle et un perte d'étanchéité du vitrage isolant. To avoid this problem of damage to the butyl bead, it is known to size the insulating glass units so as not to exceed a maximum level of mechanical stress in the sealing barriers formed by the sealant and the butyl bead. However, the sizing possibilities of insulating glass units are then limited. Thus, for triple-glazings of less than less than 800 mm, or with gas slats greater than 12 mm thick or with glass sheets greater than 6 mm thick or laminated glass, the mechanical stresses generated in the butyl bead may be high, causing damage to the butyl bead and loss of sealing of the insulating glass.
Il y a donc un besoin pour un espaceur de vitrage isolant qui permette de ne pas contraindre le dimensionnement du vitrage isolant tout en assurant une résistance à des charges climatiques ou des charges de vent élevées sans endommagement du cordon de butyle du vitrage isolant.  There is therefore a need for an insulating glazing spacer which makes it possible not to constrain the dimensioning of the insulating glazing while ensuring resistance to high climatic loads or wind loads without damaging the butyl bead of the insulating glazing unit.
Pour cela, l'invention propose un espaceur de vitrage isolant comprenant un corps longitudinal muni de deux côtés longitudinaux et deux membranes ou parties de membrane destinées à être chacune solidarisées à une feuille de verre du vitrage isolant, chaque membrane ou partie de membrane étant adaptée à être articulée sur le corps autour d'un axe parallèle à l'axe longitudinal du corps, entre une position dans laquelle la membrane ou partie de membrane est disposée contre un côté longitudinal du corps et une position dans laquelle la membrane ou partie de membrane est au moins partiellement écartée du côté longitudinal du corps.  For this, the invention proposes an insulating glazing spacer comprising a longitudinal body provided with two longitudinal sides and two membranes or membrane parts intended to be each secured to a glass sheet of the insulating glazing unit, each membrane or part of the membrane being adapted to to be articulated on the body about an axis parallel to the longitudinal axis of the body, between a position in which the membrane or membrane portion is disposed against a longitudinal side of the body and a position in which the membrane or membrane portion is at least partially separated from the longitudinal side of the body.

L'invention propose un espaceur de vitrage isolant comprenant un corps longitudinal muni de deux côtés longitudinaux et deux membranes ou parties de membrane destinées à être chacune solidarisées à une feuille de verre du vitrage isolant. Chaque membrane ou partie de membrane est adaptée à être articulée sur le corps autour d'un axe parallèle à l'axe longitudinal du corps, entre une posi- tion dans laquelle la membrane ou partie de membrane est disposée contre un côté longitudinal du corps et une position dans laquelle la membrane ou partie de membrane est au moins partiellement écartée du côté longitudinal du corps. Ainsi, chaque membrane ou partie de membrane forme une charnière par rapport au corps.  The invention proposes an insulating glazing spacer comprising a longitudinal body provided with two longitudinal sides and two membranes or membrane parts each intended to be secured to a glass sheet of the insulating glazing unit. Each membrane or membrane portion is adapted to be hinged to the body about an axis parallel to the longitudinal axis of the body, between a position in which the membrane or membrane portion is disposed against a longitudinal side of the body and a position in which the membrane or membrane portion is at least partially spaced apart from the longitudinal side of the body. Thus, each membrane or membrane portion forms a hinge relative to the body.
Lorsque le vitrage isolant se déforme sous l'effet de charges de vent ou de charges climatiques, la déformation des feuilles de verre est prise en charge par les membranes ou parties de membrane qui forment une charnière par rapport au corps, ce qui leur permet de s'écarter du corps en même temps que le cordon de butyle qui est collé entre chaque feuille de verre et une membrane ou partie de membrane afin de suivre les mouvements des feuille de verre déformées. De cette manière, le cordon de butyle n'est pas sollicité ou est très peu sollicité, ce qui permet d'empêcher son endommagement. Cet avantage est présent quel que soit la dimension du vitrage isolant. Ainsi, la fonction charnière des membranes ou parties de membrane de l'espaceur de vitrage isolant permet de ne pas contraindre le dimensionnement du vitrage isolant tout en assurant une résistance à des charges climatiques élevées sans endommagement du cordon de butyle du vitrage isolant. When the insulating glazing is deformed under the effect of wind loads or climatic loads, the deformation of the glass sheets is supported by the membranes or parts of the membrane which form a hinge relative to the body, which allows them to deviate from the body at the same time as the cord of butyl which is bonded between each glass sheet and a membrane or portion of membrane to follow the movements of the deformed glass sheets. In this way, the butyl cord is not stressed or has very little stress, which prevents its damage. This advantage is present regardless of the size of the insulating glass. Thus, the hinge function of the diaphragms or diaphragm parts of the insulating glazing spacer makes it possible not to constrain the dimensioning of the insulating glazing while ensuring resistance to high climatic loads without damaging the butyl bead of the insulating glazing unit.
Les figures 1 et 2 représentent une vue en coupe transversale d'un détail de vitrage isolant, respectivement lorsqu'il n'est pas déformé et lorsqu'il est déformé, avec un espaceur selon l'invention monté dans le vitrage isolant.  Figures 1 and 2 show a cross-sectional view of an insulating glazing detail, respectively when not deformed and when it is deformed, with a spacer according to the invention mounted in the insulating glazing unit.
Le vitrage isolant comprend au moins deux feuilles de verre 1 , 2 entre lesquelles est disposé un espaceur 3 selon l'invention. Lorsque le vitrage isolant comporte plus de deux feuilles de verre, un espaceur 3 est disposé entre chaque paire de deux feuilles de verre. Ainsi, un vitrage isolant triple comporte deux es- paceurs et un vitrage isolant quadruple comporte trois espaceurs 3.  The insulating glazing unit comprises at least two glass sheets 1, 2 between which is disposed a spacer 3 according to the invention. When the insulating glazing comprises more than two sheets of glass, a spacer 3 is disposed between each pair of two sheets of glass. Thus, a triple insulating glazing unit comprises two hoppers and a quadruple insulating glazing unit comprises three spacers 3.
L'espaceur 3 selon l'invention comprend un corps rigide comprenant deux côté longitudinaux 31 , 32 destinés à être en vis-à-vis d'une feuille de verre 1 , 2 du vitrage isolant. L'espaceur 3 comprend également deux membranes 61 , 62 qui sont disposées sur les côtés longitudinaux 31 , 32 du corps de l'espaceur 3. En variante, l'espaceur 3 comprend une membrane 6 comportant deux parties 61 , 62 qui sont disposées sur les côtés longitudinaux 31 , 32 du corps de l'espaceur 3, tel que représenté sur les figures. La membrane 6 a alors une partie supplémentaire qui relie les deux parties de membrane 61 , 62. Cette partie supplémentaire est collée sur le corps de l'espaceur, sur le bord du corps de l'espaceur destiné à être orienté vers l'extérieur du vitrage isolant, à savoir du côté des tranches 10, 20 des feuilles de verre 1 , 2. Les deux membranes ou parties de membrane 61 , 62 sont adaptées à former une charnière par rapport au corps, en particulier lorsque l'espaceur 3 est en place dans un vitrage isolant.  The spacer 3 according to the invention comprises a rigid body comprising two longitudinal sides 31, 32 intended to be vis-à-vis a glass sheet 1, 2 of the insulating glass. The spacer 3 also comprises two membranes 61, 62 which are arranged on the longitudinal sides 31, 32 of the body of the spacer 3. In a variant, the spacer 3 comprises a membrane 6 comprising two parts 61, 62 which are arranged on the longitudinal sides 31, 32 of the body of the spacer 3, as shown in the figures. The membrane 6 then has an additional portion which connects the two membrane parts 61, 62. This additional part is bonded to the spacer body, on the edge of the spacer body intended to be oriented towards the outside of the spacer. insulating glass, namely on the side of the slices 10, 20 of the glass sheets 1, 2. The two membranes or membrane parts 61, 62 are adapted to form a hinge relative to the body, in particular when the spacer 3 is in position. place in an insulating glass.
La ou les membranes sont de préférence étanches au gaz et à la vapeur d'eau. Elles présentent une certaine flexibilité. La ou les membranes sont métalli- ques (par exemple en aluminium ou en acier inoxydable) et/ou en matière plastique. The membrane or membranes are preferably impervious to gas and water vapor. They have a certain flexibility. The membrane or membranes are metallized (eg aluminum or stainless steel) and / or plastic.
Les membranes ou parties de membrane 61 , 62 sont attachées aux côtés longitudinaux 31 , 32 du corps de l'espaceur 3 à proximité du bord du corps de l'espaceur destiné à être orienté vers l'extérieur du vitrage isolant, à savoir du côté des tranches 10, 20 des feuilles de verre 1 , 2 et non du côté intérieur du vitrage isolant. Cela permet de mieux compenser les charges de vent ou les charges climatiques subies par le vitrage isolant comprenant l'espaceur 3, en particulier en cas de forte chaleur lorsque les feuilles de verre 1 , 2 se dilatent, comme représenté sur la figure 2.  The membranes or membrane parts 61, 62 are attached to the longitudinal sides 31, 32 of the body of the spacer 3 near the edge of the spacer body intended to be oriented towards the outside of the insulating glass, namely on the side. slices 10, 20 of the glass sheets 1, 2 and not the inner side of the insulating glass. This makes it possible to better compensate the wind loads or the climatic loads experienced by the insulating glazing unit comprising the spacer 3, in particular in the case of high heat when the glass sheets 1, 2 expand, as represented in FIG. 2.
Pour fabriquer un vitrage isolant, un cordon de butyle 4, 5 est déposé entre chaque côté longitudinal 31 , 32 de l'espaceur 3 et chaque feuille de verre 1 , 2. Le cordon de butyle permet à la fois de solidariser l'espaceur 3 aux feuilles de verre 1 , 2 afin de réaliser le scellement du vitrage isolant, et de réaliser une première barrière d'étanchéité au gaz et à la vapeur d'eau.  In order to manufacture an insulating glazing unit, a butyl bead 4, 5 is deposited between each longitudinal side 31, 32 of the spacer 3 and each glass sheet 1, 2. The butyl bead allows the spacer 3 to be secured at one and the same time. the glass sheets 1, 2 to seal the insulating glass, and to achieve a first barrier gas and water vapor.
Les membranes ou parties de membrane 61 , 62 peuvent ne pas adhérer aux côtés longitudinaux 31 , 32 du corps de l'espaceur 3, hormis sur la ligne d'articulation de la charnière. Toutefois, de préférence, les membranes ou parties de membrane 61 , 62 adhèrent très légèrement aux côtés longitudinaux 31 , 32 du corps de l'espaceur 3 avant le montage de l'espaceur 3 entre deux feuilles de verre. Cela permet de faciliter le montage du vitrage isolant, en particulier le dépôt du cordon de butyle 4, 5 sur les membranes ou parties de membrane 61 , 62 et l'application des membranes ou parties de membrane enduites du cordon de butyle 4, 5 contre les feuilles de verre 1 , 2. Cela permet également de faciliter la fabrication, le stockage et le transport des intercalaires sans risque d'endommagement de la membrane qui, sinon, risque de se déchirer.  The membranes or membrane portions 61, 62 may not adhere to the longitudinal sides 31, 32 of the body of the spacer 3, except on the line of articulation of the hinge. However, preferably, the diaphragms or membrane portions 61, 62 very slightly adhere to the longitudinal sides 31, 32 of the spacer body 3 before mounting the spacer 3 between two sheets of glass. This facilitates the mounting of the insulating glass, in particular the deposition of the butyl bead 4, 5 on the membranes or membrane parts 61, 62 and the application of membranes or membrane parts coated with the butyl bead 4, 5 against the glass sheets 1, 2. It also facilitates the manufacture, storage and transport of the spacers without risk of damaging the membrane which otherwise may tear.
Une fois le vitrage isolant fabriqué, l'énergie d'adhésion entre le cordon de butyle 4, 5 et chaque membrane ou partie de membrane 61 , 62 est strictement supérieure à l'énergie d'adhésion entre chaque membrane ou partie de mern- brane 61 , 62 et les côtés longitudinaux 31 , 32 du corps de l'espaceur 3. Ainsi de préférence, chaque membrane ou partie de membrane 61 , 62 adhère très légèrement aux côtés longitudinaux 31 , 32 du corps de l'espaceur 3 grâce par exemple à du polyuréthane thermofusible (« hotmelt » en anglais) sans primaire d'adhésion, ou grâce à tout autre polymère avec une faible adhésion et qui ne dégaze pas pour ne pas polluer l'intérieur du vitrage isolant. Ainsi, après montage et dès la moindre déformation du vitrage isolant due à des charges de vent ou à des charges climatiques, les membranes ou parties de membrane 61 , 62 se dé- collent des côtés longitudinaux 31 , 32 du corps de l'espaceur 3 hormis sur la ligne d'articulation de la charnière. Dès la moindre déformation du vitrage isolant, les membranes ou parties de membrane 61 , 62, en étant articulées sur les côtés longitudinaux du corps de l'espaceur 3, permettent donc de compenser la déformation des feuilles de verre 1 , 2 en suivant les mouvements des feuilles de verre et ainsi d'éviter tout endommagement du cordon de butyle 4, 5. Once the insulating glazing unit has been fabricated, the adhesion energy between the butyl bead 4, 5 and each membrane or membrane portion 61, 62 is strictly greater than the adhesion energy between each membrane or part of the moth brane. 61, 62 and the longitudinal sides 31, 32 of the body of the spacer 3. Thus, preferably, each membrane or portion of membrane 61, 62 adheres very slightly to the longitudinal sides 31, 32 of the body of the spacer 3 for example by to hot melt polyurethane ("hotmelt" in English) without primary adhesion, or thanks to any other polymer with low adhesion and that does not degass not to pollute the insulating glass interior. Thus, after assembly and at the slightest deformation of the insulating glazing due to wind loads or to climatic loads, the diaphragms or membrane parts 61, 62 are disengaged from the longitudinal sides 31, 32 of the spacer body 3 except on the hinge line of the hinge. At the slightest deformation of the insulating glazing, the diaphragms or diaphragm parts 61, 62, being articulated on the longitudinal sides of the body of the spacer 3, thus make it possible to compensate the deformation of the glass sheets 1, 2 by following the movements glass sheets and thus avoid any damage to the butyl bead 4, 5.
Dès fabrication de l'espaceur si les membranes ou parties de membrane n'adhèrent pas du tout aux côtés longitudinaux du corps ou dès la moindre déformation du vitrage si les si les membranes ou parties de membrane adhèrent très légèrement aux côtés longitudinaux du corps, chaque membrane ou partie de membrane 61 , 62 est articulée sur le corps autour d'un axe parallèle à l'axe longitudinal du corps, en formant charnière par rapport au corps. Chaque membrane ou partie de membrane 61 , 62 peut ainsi bouger entre une position dans laquelle elle est disposée contre un côté longitudinal 31 , 32 du corps et une position dans laquelle elle est au moins partiellement écartée du côté longitudinal 31 , 32 du corps. En effet, dans le mode de réalisation de la figure 2, il reste toujours au moins une ligne de contact entre les membranes ou parties de membrane et les côtés longitudinaux du corps pour l'articulation.  As soon as the spacer is made, if the membranes or parts of the membrane do not adhere at all to the longitudinal sides of the body or the slightest deformation of the glazing if the membranes or parts of the membrane adhere very slightly to the longitudinal sides of the body, each membrane or portion of membrane 61, 62 is articulated on the body about an axis parallel to the longitudinal axis of the body, forming hinge relative to the body. Each membrane or portion of membrane 61, 62 can thus move between a position in which it is disposed against a longitudinal side 31, 32 of the body and a position in which it is at least partially spaced from the longitudinal side 31, 32 of the body. Indeed, in the embodiment of Figure 2, there is always at least one line of contact between the membranes or membrane parts and the longitudinal sides of the body for the joint.
Le vitrage isolant comprend également un mastic 8 qui est disposé entre les feuilles de verre 1 , 2 du vitrage isolant, entre le bord de l'espaceur 3 orienté vers l'extérieur du vitrage isolant et les tranches 10, 20 des feuilles de verre 1 , 2. Le mastic 8 permet de réaliser une deuxième barrière d'étanchéité au gaz et à la vapeur d'eau. Le mastic 8 est par exemple du polyuréthane, du polysulfure ou du silicone.  The insulating glazing unit also comprises a putty 8 which is placed between the glass sheets 1, 2 of the insulating glazing unit, between the edge of the spacer 3 facing the outside of the insulating glazing unit and the slices 10, 20 of the glass sheets 1 , 2. Putty 8 makes it possible to produce a second barrier to seal gas and water vapor. Putty 8 is for example polyurethane, polysulfide or silicone.
Le corps de l'espaceur 3 est de préférence un profilé creux rempli de des- sicant 7 pour permettre d'absorber de l'humidité qui pourrait se trouver à l'intérieur du vitrage isolant.  The body of the spacer 3 is preferably a hollow profile filled with desiccant 7 to allow moisture to be absorbed which might be inside the insulating glass.
Le corps de l'espaceur 3 est de préférence métallique, par exemple en aluminium ou en acier, ou en matière plastique, ou encore en matière composite tel que la matière commercialisée sous la marque LURAN par l'entreprise BASF, la matière composite étant du styrène acrylonitrile (SAN) comprenant des fibres de verre. The body of the spacer 3 is preferably metallic, for example aluminum or steel, or plastic, or composite material such as the material marketed under the trademark LURAN by the company BASF, the composite material being styrene acrylonitrile (SAN) comprising glass fibers.
Les figures 3 et 4 représentent une vue en coupe transversale d'un espa- ceur 3 selon d'autres modes de réalisation de l'invention.  Figures 3 and 4 show a cross-sectional view of a spacer 3 according to other embodiments of the invention.
Dans ces modes de réalisation, les membranes ou parties de membrane 61 , 62 ont la forme d'un accordéon ou d'un soufflet.  In these embodiments, the membranes or membrane portions 61, 62 are in the form of an accordion or bellows.
Dans le mode de réalisation de la figure 3, seule une partie de la membrane ou partie de membrane a la forme d'un accordéon ou d'un soufflet, avec un seul pli.  In the embodiment of Figure 3, only a portion of the membrane or membrane portion is in the form of an accordion or bellows, with a single fold.
Dans le mode de réalisation de la figure 4, la membrane ou partie de membrane a la forme d'un accordéon ou d'un soufflet avec plusieurs plis.  In the embodiment of Figure 4, the diaphragm or portion of the membrane is in the form of an accordion or bellows with several folds.
La forme d'accordéon ou de soufflet permet à la membrane ou partie de membrane 61 , 62 de se déployer sous l'effet d'une déformation du vitrage isolant, ce qui permet de mieux épouser les mouvements des feuilles de verre, en expansion comme en contraction. Cela permet d'éviter que des contraintes trop fortes pèsent sur l'articulation entre la membrane et le côté longitudinal du corps ou entre la partie de membrane et la partie supplémentaire de la membrane 6, ce qui permet d'éviter un déchirement de la membrane ou partie de membrane.  The accordion or bellows shape allows the diaphragm or part of the membrane 61, 62 to expand under the effect of a deformation of the insulating glazing, which makes it possible to better match the movements of the expanding glass sheets as in contraction. This makes it possible to prevent too much stress on the articulation between the membrane and the longitudinal side of the body or between the membrane part and the additional part of the membrane 6, which makes it possible to prevent tearing of the membrane or part of the membrane.
Avant montage sur un vitrage isolant, les plis de chaque membrane ou partie de membrane 61 , 62 peuvent adhérer très légèrement entre eux de façon à faciliter le montage du vitrage isolant. Une fois le vitrage isolant fabriqué, et dès la moindre déformation du vitrage isolant due à des charges de vent ou à des charges climatiques, les plis de chaque membrane ou partie de membrane 61 , 62 se décollent les uns des autres hormis sur les lignes d'articulation des plis. Ainsi, dès la moindre déformation du vitrage isolant, les plis des membranes ou parties de membrane 61 , 62 permettent de compenser la déformation des feuilles de verre 1 , 2 en suivant les mouvements des feuilles de verre et ainsi d'éviter tout endommagement du cordon de butyle 4, 5.  Before mounting on an insulating glass, the folds of each membrane or membrane portion 61, 62 may adhere very slightly to each other so as to facilitate the mounting of the insulating glass. Once the insulating glazing is manufactured, and as soon as the insulating glazing is deformed due to wind loads or climatic loads, the folds of each membrane or membrane portion 61, 62 separate from each other except on the lines articulation of the folds. Thus, at the slightest deformation of the insulating glass, the folds of the membranes or membrane parts 61, 62 make it possible to compensate for the deformation of the glass sheets 1, 2 by following the movements of the glass sheets and thus to prevent any damage to the cord butyl 4, 5.
Dans le mode de réalisation de la figure 4, comme dans le mode de réalisation de la figure 2, il reste toujours au moins une ligne de contact entre les membranes ou parties de membrane et les côtés longitudinaux du corps pour l'articulation puisque la ligne de contact entre les membranes ou parties de membrane et le corps est située à une extrémité des côtés longitudinaux du corps. In the embodiment of FIG. 4, as in the embodiment of FIG. 2, there is always at least one line of contact between the membranes or membrane parts and the longitudinal sides of the body for the joint since the line of contact between the membranes or membrane parts and the body is located at one end of the longitudinal sides of the body.
Dans le mode de réalisation de la figure 3, la ligne de contact entre les membranes ou parties de membrane et le corps est décalée vers le fond du corps. Lorsque les membranes ou parties de membrane s'écartent des côtés longitudinaux du corps, cet écartement peut se faire sans qu'il n'y ait plus de point de contact entre les membranes ou parties de membrane et les côtés longitudinaux du corps.  In the embodiment of Figure 3, the line of contact between the membranes or membrane portions and the body is shifted to the bottom of the body. When the diaphragms or parts of the membrane deviate from the longitudinal sides of the body, this spacing can be done without there being more point of contact between the diaphragms or parts of the membrane and the longitudinal sides of the body.
L'invention concerne également un connecteur en équerre adapté à être disposé dans le coin d'un vitrage isolant, entre deux espaceurs.  The invention also relates to an angled connector adapted to be disposed in the corner of an insulating glazing between two spacers.
Le connecteur comprend un corps en équerre muni de deux branches reliées par un coin. L'extrémité de chaque branche est destinée à être insérée dans un espaceur et chaque branche et chaque coin est muni de deux côtés longitudinaux. Le connecteur comprend également deux membranes ou parties de mern- brane destinées à être chacune solidarisées à une feuille de verre du vitrage isolant. Chaque membrane ou partie de membrane est adaptée à être articulée sur les branches et le coin autour d'un axe parallèle à l'axe longitudinal des branches et du coin, entre une position dans laquelle la membrane ou partie de membrane est disposée contre un côté longitudinal des branches et du coin et une position dans laquelle la membrane ou partie de membrane est écartée du côté longitudinal des branches et du coin. Chaque membrane ou partie de membrane a la forme d'un accordéon ou d'un soufflet ayant au moins un pli. Chaque membrane ou partie de membrane est adaptée à former une charnière par rapport au corps en équerre lorsque le connecteur est monté dans un vitrage isolant. Le corps en équerre forme un unique profilé creux rempli de dessicant. Le corps en équerre est métallique, en matière plastique ou en matière composite tel qu'en SAN avec des fibres de verre. Les membranes ou parties de membrane sont métalliques et/ou en matière plastique.  The connector comprises a square body provided with two branches connected by a corner. The end of each branch is intended to be inserted into a spacer and each branch and each corner is provided with two longitudinal sides. The connector also comprises two membranes or parts of membrane intended to be each secured to a glass sheet of the insulating glazing unit. Each membrane or membrane portion is adapted to be articulated on the limbs and the corner around an axis parallel to the longitudinal axis of the limbs and the wedge, between a position in which the membrane or membrane portion is disposed against one side longitudinal direction of the branches and the corner and a position in which the membrane or part of the membrane is spaced apart from the longitudinal side of the branches and the corner. Each membrane or membrane portion is in the form of an accordion or bellows having at least one fold. Each membrane or membrane portion is adapted to form a hinge relative to the bracket body when the connector is mounted in an insulating glass. The angled body forms a single hollow section filled with desiccant. The angled body is metal, plastic or composite material such as SAN with glass fibers. The membranes or membrane parts are metallic and / or plastic.
L'invention concerne également un vitrage isolant comprenant quatre es- paceurs 3 selon l'invention et quatre connecteurs selon l'invention, les espaceurs 3 étant reliés entre eux deux à deux par un connecteur.  The invention also relates to an insulating glazing unit comprising four hoppers 3 according to the invention and four connectors according to the invention, the spacers 3 being connected together in pairs by a connector.
Ainsi, l'invention, en particulier l'espaceur, permet de fabriquer des vitrages isolants de toutes dimensions avec des performances thermiques optimales, par exemple un triple vitrage avec deux lames de gaz d'épaisseur 19 mm et de hauteur et largeur inférieure à 80 cm, sans prendre de risque sur leur durée de vie. Thus, the invention, in particular the spacer, makes it possible to manufacture insulating glazings of all sizes with optimum thermal performance, by example a triple glazing with two blades of gas 19 mm thick and height and width less than 80 cm, without taking risks over their lifetime.
De plus, des mesures ont montré qu'un vitrage isolant équipé d'espaceurs selon l'invention est plus étanche (environ deux fois plus) qu'un vitrage isolant équipé d'espaceurs sans membrane ou partie de membrane articulée.  In addition, measurements have shown that an insulating glazing unit equipped with spacers according to the invention is more watertight (about twice as much) than an insulating glazing unit equipped with spacers without a diaphragm or an articulated membrane part.
