Description

CONNECTEUR POUR RACCORDER DEUX EXTREMITES CREUSES DE PROFILE CONNECTOR FOR CONNECTING TWO HOLLOW PROFILE ENDS
L'invention concerne un connecteur pour raccorder deux extrémités creuses de profilé, le connecteur étant destiné à être inséré entre les parois internes des extrémités de profilé, et comportant un corps qui présente deux faces opposées et deux parois latérales. Un tel connecteur est par exemple utilisé pour relier des extrémités de profilé afin de former un cadre qui constitue l'intercalaire d'un vitrage isolant. L'invention sera plus particulièrement décrite en regard d'une telle application, qui n'est cependant nullement limitative et peut s'adresser à d'autres applications non verrières. Un type de vitrage isolant bien connu comporte deux feuilles de verre qui sont espacées par une lame de gaz tel que de l'air et, qui sont écartées et réunies au moyen d'un cadre entretoise constitué par des profilés métalliques creux plies ou par des profilés assemblés par des pièces médianes et/ou d'angle nommées connecteurs. Les profilés sont garnis d'un tamis moléculaire qui a notamment pour rôle d'absorber les molécules d'eau emprisonnées dans la lame d'air intercalaire au moment de la fabrication du vitrage et qui seraient susceptibles de se condenser par temps froid, entraînant l'apparition de buée. Pour assurer l'étanchéité du vitrage, le cadre entretoise est collé aux feuilles de verre par un cordon élastomère du type caoutchouc butyl appliqué directement sur les profilés formant le cadre entretoise par extrusion au travers d'une buse. Une fois le vitrage assemblé, le cordon élastomère d'étanchéité joue un rôle de maintien mécanique provisoire des feuilles de verre. Enfin, on injecte dans la gorge périphérique délimitée par les deux feuilles de verre et le cadre entretoise un mastic d'étanchéité réticulable du type polysulfure ou polyuréthane qui termine l'assemblage mécanique des feuilles de verre. Le caoutchouc butyl a principalement comme rôle de rendre étanche l'intérieur du vitrage à la vapeur d'eau, tandis que le mastic assure une étanchéité à l'eau liquide ou aux solvants. On connaît comme connecteur pour profilés d'entretoise de vitrage isolant celui par exemple décrit dans la demande de brevet EP 0 283 689. Ce connecteur est inséré à force dans les extrémités creuses de profilé et maintenu fermement grâce à des saillies latérales de retenue qui sont orientées dans le sens opposé au sens de traction selon lequel il conviendrait de tirer sur les extrémités de profilé en cas de démontage. Une fois les deux extrémités de profilé aboutées, il existe irrémédiablement au niveau de la jonction un espace minime qui doit nécessairement être étanché au gaz. On ajoute généralement au niveau de cette jonction et sur les faces de l'intercalaire qui seront opposées à la lame de gaz, un joint d'étanchéité du type butyl comme déjà expliqué plus haut, ou bien davantage de mastic. Dans la demande de brevet US 2003/0059253, l'étanchéité au niveau de la jonction des deux extrémités de profilé est réalisée avec un matériau d'étanchéité qui est, non pas ajouté à l'extérieur des extrémités de profilé après aboutement, mais disposé à l'intérieur des deux extrémités creuses de profilé, plus exactement agencé dans une cavité prévue dans le corps du connecteur au niveau de la jonction. C'est un matériau qui est injecté dans la cavité du connecteur après le raccordement de l'une des extrémités de profilé et qui flue aux endroits appropriés pour former l'étanchéité, la seconde extrémité étant ensuite rapportée contre la première. Cependant, ces diverses méthodes pour étancher la jonction entre les deux extrémités de profilé engendrent dans la fabrication d'un cadre une opération supplémentaire de dépôt de matière étanche, ce qui nécessite un apport de matière et un outillage spécifique pour assurer cette opération. En outre, si sur certaines lignes de fabrication, l'opération d'étancher est faite ultérieurement à l'opération de raccordement des extrémités de profilé (en particulier lorsque le matériau est rapporté après aboutement), il est nécessaire par des moyens adaptés de connaître la position exacte de la ou des jonctions afin de rapporter la matière au bon endroit. Aussi, une telle opération ne participe pas à un économie des coûts de fabrication et à la rapidité de fabrication. Or, il est toujours souhaitable dans un procédé de fabrication de réduire le nombre d'étapes nécessaires et/ou de les simplifier ainsi que de minimiser les coûts de fabrication. L'invention a donc pour but de simplifier le raccordement de deux extrémités de profilé qui doivent au niveau de leur jonction être impérativement étanchées. Selon l'invention, le connecteur est caractérisé en ce qu'il comporte des moyens d'étanchéité aux gaz qui sont disposés de manière solidaire sur l'une des faces du corps et qui sont adaptés à subir une compression. Ainsi, les moyens d'étanchéité sont intrinsèques au connecteur. Une fois le raccordement effectué, l'étanchéité est également assurée. Aucune opération supplémentaire pour étancher, contrairement à l'art antérieur, n'a besoin d'être effectuée. Avantageusement, le connecteur est réalisé par moulage et est réalisé en une seule pièce. Les moyens d'étanchéité sont constitués d'un matériau élastique de dureté comprise entre 20 et 50 Shore A. Il s'agit par exemple d'un matériau à base de polyéthylène, et/ou polypropylène, et ou PMMA, et/ou polyamide. Selon une caractéristique, le corps du connecteur est longitudinal et comporte les moyens d'étanchéité dans sa partie médiane. Dans une variante de réalisation, le corps du connecteur comporte deux ailes formant un angle, les moyens d'étanchéité s'étendant en continu sur au moins une partie de chacune des ailes et sur l'angle. Selon une autre caractéristique, le connecteur comporte au moins une pièce de support sur laquelle sont rapportés les moyens d'étanchéité par clipsage ou par collage. Avantageusement, la pièce de support est un élément mobile par rapport au corps du connecteur. De préférence, la pièce de support est rendue amovible par le biais d'une charnière. Selon une autre caractéristique, le connecteur comporte au moins un système de poussoir qui est adapté, à faire saillie par rapport à la face opposée à celle munie des moyens d'étanchéité, ou à être rentré dans le corps du connecteur. De préférence, le système de poussoir consiste en un ergot agencé sur la pièce de support et en un évidemment agencé dans le corps du connecteur et traversant les deux faces opposées du connecteur, l'ergot coopérant avec l'évidemment. Selon une variante de réalisation, les moyens d'étanchéité se présentent sous la forme d'une pastille plate. Les moyens d'étanchéité peuvent présenter sur la face opposée à celle en regard du corps du connecteur des nervures qui sont perpendiculaires aux parois latérales. Selon une autre variante de réalisation, les moyens d'étanchéité présentent à l'opposé de la face en regard du corps du connecteur une forme adaptée concave ou une forme adaptée conique à sommet plat pour exercer la force de compression nécessaire à l'étanchéité. Pour avantageusement savoir jusqu'à quel endroit il convient d'introduire le connecteur dans les extrémités de profilé, les parois latérales du corps du connecteur comportent en milieu du corps ou des ailes du corps, des butées. Ainsi, il est possible de constituer un ensemble formé d'au moins deux extrémités creuses de profilé à parois internes, et d'au moins un connecteur selon l'invention, les moyens d'étanchéité étant comprimés contre les parois internes des extrémités creuses de profilé au niveau de la jonction des deux extrémités de profilé ou au niveau de leur angle d'aboutement. L'ergot de la pièce de support des moyens d'étanchéité est alors logé dans l'ouverture du connecteur lorsque le connecteur comporte au moins un système de poussoir. Un tel ensemble permet par exemple de réaliser un cadre pour être utilisé par exemple dans un vitrage isolant. Pour procéder au raccordement de deux extrémités creuses de profilé à l'aide d'un connecteur selon l'invention, le connecteur est inséré par l'une de ses extrémités dans la partie creuse de l'une des extrémités de profilé, la seconde extrémité de profilé est alors rapportée autour de l'extrémité opposée libre du connecteur en établissant une force de poussée sur chacune des extrémités de profilé jusqu'à obtenir leur aboutement. D'autres avantages et caractéristiques de l'invention vont à présent être décrits plus en détail en regard des dessins annexés sur lesquels : • La figure 1 est une vue de profil du connecteur de l'invention selon un exemple de réalisation; • La figure 2 est une autre vue de profil du connecteur selon la figure 1 ; « La figure 3 est une vue en coupe du raccordement de deux extrémités de profilé à l'aide du connecteur selon la ligne A- A de la figure 1 ; • La figure 4 est une vue en coupe du connecteur associé à une extrémité de profilé ; • Les figures 5a et 5b sont des vues en coupe du connecteur selon deux autres exemples de réalisation; • Les figures 6a et 6b illustrent schématiquement un connecteur d'angle en vue d'assembler deux extrémités de profilé selon un angle; • La figure 7 illustrent de points de mesure du pourcentage de gaz échappé après des tests de durabilité sur des vitrages isolants. La figure 1 illustre un exemple de réalisation d'un connecteur 1 selon l'invention destiné à raccorder, conformément à la figure 3, deux extrémités creuses 2 et 3 de profilé. Le connecteur 1 intègre des moyens d'étanchéité 15, décrits plus loin, qui sont agencés au niveau de la jonction 4 des deux extrémités de profilé et contre d'une part une face 20a et ses arêtes latérales, et d'autre part une face 30a et ses arêtes latérales, respectivement des parois internes 20 et 30 des extrémités de profilé. Le connecteur 1 comporte un corps longitudinal 10 qui présente deux faces opposées 11 et 12, et deux parois latérales opposées 13 et 14. Le corps 10 est formé de préférence par moulage avec l'injection d'une matière plastique sans ou avec peu de plastifiant. En variante, il peut être métallique. Les moyens d'étanchéité aux gaz 15 sont disposés sur la partie médiane 11a de l'une des faces 11 du corps 10. Ces moyens d'étanchéité sont adaptés à subir une compression. Ils sont ainsi en un matériau élastique de dureté comprise entre 20 et 50 Shore A. Ce matériau n'a pas besoin d'avoir des propriétés de collage, il doit simplement présenter l'élasticité adéquate pour pouvoir se déformer lors de sa compression contre les parois internes des extrémités de profilé, tout en absorbant les variations de forme du profilé et tout en gardant une forme sensiblement égale à celle d'origine avant compression pour assurer sa tenue mécanique au cours du temps. Un tel matériau, qui soit en outre étanche aux gaz, est par exemple un matériau de type "hot melt" tel que du polyuréthane réticulable ou un matériau à base de polyéthylène, polypropylène, PM A, polyamide. On peut citer le matériau de marque Vitaprène commercialisé par la société VTC. Le connecteur 1 comporte avantageusement une pièce de support 16 sur laquelle reposent les moyens d'étanchéité 15. La pièce de support présente une surface équivalente à la surface des moyens d'étanchéité. Les moyens d'étanchéité 15 sont solidarisés avec la pièce de support 16 par collage, ou par clipsage selon des formes coopérantes de la pièce et des moyens d'étanchéité non illustrées ici. Le connecteur 1 comporte également un système de poussoir 18, tel qu'illustré sur la figure 3, qui est adapté à être logé dans le corps 10 du connecteur, et à faire saillie par rapport à la face 12 opposée à la face munie des moyens d'étanchéité 15. Le système de poussoir 18 est composé d'un ergot 18a intégré à la face 16a de la pièce de support 16, opposée aux moyens d'étanchéité 15, et d'un évidemment 18b traversant les faces 11 et 12 du corps du connecteur dans sa partie médiane. L'ergot 18a est de forme adaptée à l'évidemment 18b pour coopérer avec celui-ci selon un emboîtement serré. De manière à assurer cette coopération, la pièce de support 16 est rendue mobile par rapport au corps 10 du connecteur. Elle consiste soit en un élément amovible, soit en un élément mobile par le biais d'une charnière 17 tel qu'illustré sur la figure 2. On préférera la seconde solution pour des raisons de simplicité de fabrication du connecteur. Le connecteur étant formé par moulage, la charnière 17 reliant la pièce de support et le corps du connecteur permet de n'avoir à démouler qu'une seule pièce combinée. Dans cet exemple de réalisation, les moyens d'étanchéité 15 présente la forme d'une pastille plate. Cette pastille comporte sur sa face externe opposée à la pièce de support 16, des nervures 15a qui permettent de compenser les défauts de planéité des parois internes 20, 30 des extrémités de profilé et de compenser les tolérances de forme de la section des extrémités de profilé, et assurer ainsi une parfaite compression de la pastille contre les parois en position jointe des extrémités de profilé. A noter que ces nervures ne sont pas nécessairement utiles lorsque le matériau des moyens d'étanchéité présente une dureté proche de 50 Shore A. Le connecteur 1 sert donc au raccordement de deux extrémités 2 et 3 de profilé. Ces extrémités de profilé peuvent être en inox, en aluminium, en plastique ou en tout autre matériau selon la destination du profilé.The invention relates to a connector for connecting two hollow profile ends, the connector being intended to be inserted between the internal walls of the profile ends, and comprising a body which has two opposite faces and two side walls. Such a connector is for example used to connect the ends of the profile in order to form a frame which constitutes the interlayer of an insulating glazing. The invention will be more particularly described with regard to such an application, which is however in no way limiting and can be addressed to other non-glass applications. A well-known type of insulating glazing comprises two sheets of glass which are spaced apart by a blade of gas such as air and which are separated and joined by means of a spacer frame constituted by folded hollow metal profiles or by profiles assembled by middle and / or corner pieces called connectors. The profiles are lined with a molecular sieve which in particular has the role of absorbing the water molecules trapped in the interlayer of air during the production of the glazing and which would be liable to condense in cold weather, causing the appearance of fogging. To ensure the sealing of the glazing, the spacer frame is glued to the glass sheets by an elastomeric cord of the butyl rubber type applied directly to the profiles forming the spacer frame by extrusion through a nozzle. Once the glazing is assembled, the elastomeric sealing bead acts as a temporary mechanical support for the glass sheets. Finally, a crosslinkable sealing mastic of the polysulfide or polyurethane type is injected into the peripheral groove delimited by the two glass sheets and the spacer frame, which completes the mechanical assembly of the glass sheets. The main role of butyl rubber is to seal the interior water vapor glazing, while the sealant seals with liquid water or solvents. The connector for insulating glazing spacer profiles is known as that described for example in patent application EP 0 283 689. This connector is force-fitted into the hollow ends of the profile and held firmly by lateral retaining projections which are oriented in the opposite direction to the direction of traction according to which the profile ends should be pulled in the event of disassembly. Once the two profile ends are joined, there is irremediably at the junction a minimal space which must necessarily be sealed with gas. We generally add at this junction and on the faces of the interlayer which will be opposite the gas slide, a butyl type seal as already explained above, or even more putty. In the patent application US 2003/0059253, the sealing at the junction of the two profile ends is carried out with a sealing material which is not added to the outside of the profile ends after abutment, but disposed inside the two hollow profile ends, more precisely arranged in a cavity provided in the body of the connector at the junction. It is a material which is injected into the connector cavity after the connection of one of the profile ends and which flows at the appropriate places to form the seal, the second end then being brought against the first. However, these various methods for sealing the junction between the two ends of the profile generate in the manufacture of a frame an additional operation of depositing tight material, which requires a supply of material and specific tools to ensure this operation. In addition, if on certain production lines, the sealing operation is done after the connection operation of the profile ends (in particular when the material is added after abutment), it is necessary by suitable means to know the exact position of the joint (s) in order to bring the material to the right place. Also, such an operation does not contribute to saving manufacturing costs and speed of manufacture. However, it is always desirable in a manufacturing process to reduce the number of necessary steps and / or to simplify them as well as to minimize the manufacturing costs. The invention therefore aims to simplify the connection of two profile ends which must at their junction be imperatively sealed. According to the invention, the connector is characterized in that it comprises gas sealing means which are arranged integrally on one of the faces of the body and which are adapted to undergo compression. Thus, the sealing means are intrinsic to the connector. Once the connection is made, sealing is also ensured. No additional sealing operation, unlike the prior art, needs to be carried out. Advantageously, the connector is produced by molding and is produced in one piece. The sealing means consist of an elastic material with a hardness of between 20 and 50 Shore A. This is for example a material based on polyethylene, and / or polypropylene, and or PMMA, and / or polyamide . According to one characteristic, the body of the connector is longitudinal and comprises the sealing means in its middle part. In an alternative embodiment, the connector body comprises two wings forming an angle, the sealing means extending continuously over at least part of each of the wings and over the angle. According to another characteristic, the connector comprises at least one support piece on which the sealing means are attached by clipping or by bonding. Advantageously, the support part is a movable element relative to the body of the connector. Preferably, the support piece is made removable by means of a hinge. According to another characteristic, the connector comprises at least one pusher system which is adapted, to protrude relative to the face opposite to that provided with the sealing means, or to be retracted into the body of the connector. Preferably, the pusher system consists of a lug arranged on the support piece and in a recess arranged in the body of the connector and passing through the two opposite faces of the connector, the lug cooperating with the obvious. According to an alternative embodiment, the sealing means are in the form of a flat pellet. The sealing means may have ribs on the face opposite to that opposite the body of the connector which are perpendicular to the side walls. According to another alternative embodiment, the sealing means have, opposite the face opposite the body of the connector, a suitable concave shape or a suitable conical shape with a flat top to exert the compressive force necessary for sealing. In order to advantageously know to which point the connector should be introduced into the profile ends, the side walls of the body of the connector have stops in the middle of the body or of the body's wings. Thus, it is possible to constitute an assembly formed of at least two hollow ends of profile with internal walls, and at least one connector according to the invention, the sealing means being compressed against the internal walls of the hollow ends of profile at the junction of the two profile ends or at their abutment angle. The lug of the support part of the sealing means is then housed in the opening of the connector when the connector comprises at least one pusher system. Such an assembly allows for example to produce a frame to be used for example in an insulating glazing. To connect two hollow profile ends using a connector according to the invention, the connector is inserted at one of its ends into the hollow part of one of the profile ends, the second end profile is then reported around the opposite free end of the connector by establishing a pushing force on each of the profile ends until their abutment. Other advantages and characteristics of the invention will now be described in more detail with reference to the appended drawings in which: • Figure 1 is a side view of the connector of the invention according to an exemplary embodiment; • Figure 2 is another side view of the connector according to Figure 1; “Figure 3 is a sectional view of the connection of two profile ends using the connector along line A- A of Figure 1; • Figure 4 is a sectional view of the connector associated with a profile end; • Figures 5a and 5b are sectional views of the connector according to two other embodiments; • Figures 6a and 6b schematically illustrate a corner connector to assemble two profile ends at an angle; • Figure 7 illustrates points of measurement of the percentage of gas escaped after durability tests on insulating glazing. Figure 1 illustrates an exemplary embodiment of a connector 1 according to the invention intended to connect, in accordance with Figure 3, two hollow ends 2 and 3 of profile. The connector 1 integrates sealing means 15, described below, which are arranged at the junction 4 of the two profile ends and against on the one hand a face 20a and its lateral edges, and on the other hand a face 30a and its lateral edges, respectively of the internal walls 20 and 30 of the profile ends. The connector 1 comprises a longitudinal body 10 which has two opposite faces 11 and 12, and two opposite side walls 13 and 14. The body 10 is preferably formed by molding with the injection of a plastic material without or with little plasticizer . Alternatively, it can be metallic. The gas sealing means 15 are arranged on the middle part 11a of one of the faces 11 of the body 10. These sealing means are adapted to undergo compression. They are thus made of an elastic material with a hardness of between 20 and 50 Shore A. This material does not need to have bonding properties, it must simply have the adequate elasticity in order to be able to deform during its compression against the internal walls of the profile ends, while absorbing the variations in shape of the profile and while keeping a shape substantially equal to that of the original before compression to ensure its mechanical strength over time. Such a material, which is also gas-tight, is for example a material of the "hot melt" type such as crosslinkable polyurethane or a material based on polyethylene, polypropylene, PM A, polyamide. Mention may be made of the Vitaprene brand material sold by the company VTC. The connector 1 advantageously comprises a support part 16 on which the sealing means 15 rest. The support part has an area equivalent to the surface of the sealing means. The sealing means 15 are secured to the support part 16 by gluing, or by clipping in cooperating forms of the part and sealing means not illustrated here. The connector 1 also includes a pusher system 18, as illustrated in FIG. 3, which is adapted to be housed in the body 10 of the connector, and to protrude relative to the face 12 opposite the face provided with the means sealing 15. The pusher system 18 is composed of a lug 18a integrated into the face 16a of the support part 16, opposite the sealing means 15, and of an obviously 18b passing through the faces 11 and 12 of the body of the connector in its middle part. The lug 18a is of a shape adapted to the recess 18b to cooperate with the latter in a tight fit. In order to ensure this cooperation, the support part 16 is made movable relative to the body 10 of the connector. It consists either of a removable element, or of a mobile element by means of a hinge 17 as illustrated in FIG. 2. The second solution will be preferred for reasons of simplicity of manufacture of the connector. The connector being formed by molding, the hinge 17 connecting the support piece and the connector body makes it possible to have to unmold only one combined part. In this exemplary embodiment, the sealing means 15 has the form of a flat pellet. This patch has on its external face opposite the support part 16, ribs 15a which make it possible to compensate for the flatness defects of the internal walls 20, 30 of the profile ends and to compensate for the shape tolerances of the section of the profile ends. , and thus ensure perfect compression of the patch against the walls in the joined position of the profile ends. Note that these ribs are not necessarily useful when the material of the sealing means has a hardness close to 50 Shore A. The connector 1 is therefore used to connect two ends 2 and 3 of profile. These profile ends can be made of stainless steel, aluminum, plastic or any other material depending on the destination of the profile.
L'aboutement de deux extrémités de profilé peut servir à la constitution d'un cadre par exemple, destiné notamment à la fabrication d'un vitrage isolant. Les extrémités creuses 2 et 3 de profilé peuvent être fermées sur l'ensemble de leur périphérie, ou non. Dans ce dernier cas (figure 4), l'extrémité de profilé, 2 par exemple, est au moins adaptée à maintenir le connecteur 1 en position introduite, c'est-à-dire contre les parois latérales 2a de l'extrémité de profilé et contre des retours 2b des dites parois latérales, la face 12 du connecteur reposant sur ces retours. Le raccordement à l'aide du connecteur 1 de l'invention s'effectue de la manière suivante. La pièce de support 16 du connecteur est positionnée sur la partie médiane 11a du connecteur de façon que l'ergot 18a soit logé dans l'évidemment 18b en position poussée, l'ergot faisant saillie par rapport à la face 12 du connecteur. Le connecteur 1 est inséré par l'une de ses extrémités dans la partie creuse de l'une des extrémités de profilé sans que nécessairement, le connecteur soit enfoncé jusqu'au niveau des moyens d'étanchéité 15. La seconde extrémité de profilé est alors rapportée autour de l'extrémité opposée libre du connecteur. En établissant une force de poussée sur chacune des extrémités 2 et 3 de profilé, on rapproche ces extrémités jusqu'à obtenir leur aboutement au niveau d'une butée 19 agencée sur chacune des parois 13 et 14 du connecteur et au milieu du corps 10, les moyens d'étanchéité 15 étant répartis de chaque côté de ces butées. Lors du rapprochement des extrémités 2 et 3, les faces des parois internes 20b et 30b des extrémités de profilé viennent en contact avec l'ergot 18a faisant saillie par rapport à la face 12 du connecteur, ce qui exerce une force de poussée contre l'ergot en saillie et comprime alors les moyens d'étanchéité 15, disposés à l'opposé de l'ergot, contre la face opposée 20a, 30a des parois internes 20, et 30 des extrémités de profilé. La jonction 4 est ainsi rendue étanche au niveau au moins de l'une des faces et des arêtes latérales correspondantes des parois internes de chacune des extrémités 2 et 3 de profilé. L'exemple de réalisation donné ci-dessus du connecteur comporte comme déjà expliqué une pastille plate de matériau d'étanchéité combinée à un système de poussoir pour exercer une force de compression lorsque le connecteur est inséré dans les extrémités de profilé. Dans un autre exemple de réalisation, plutôt que de disposer d'une telle combinaison, il est possible d'envisager pour exercer une telle force de compression une forme adaptée des moyens d'étanchéité. Ainsi une forme de section concave (figure 5a), ou une forme de section conique à sommet plat (figure 5b), dont la largeur de la courbure ou du sommet plat soit au moins sensiblement plus grande que la largeur de l'interstice de jonction 4, conviendrait. La hauteur des moyens d'étanchéité est adaptée de manière à obtenir une introduction aisée du connecteur dans les extrémités de profilé et à permettre l'aboutement des deux extrémités de profilé tout en assurant une compression desdits moyens contre les parois des extrémités de profilé lorsque celles-ci sont aboutées. Bien entendu, dans ce mode de réalisation, la pièce de support 16 fait partie intégrante du corps du connecteur, elle n'a pas besoin d'être rendue mobile. La description ci-dessus a été faite pour un raccordement de deux extrémités de profilé positionnés dans un même plan. Sur le même principe, un connecteur d'angle peut être réalisé pour raccorder deux extrémités de profilé positionnés selon un angle d'aboutement. La figure 6a illustre schématiquement le connecteur 1 avant montage. Il comporte deux ailes 10a et 10b faisant un angle équivalent à l'angle avec lequel on désire connecter les extrémités de profilé 2 et 3 (ici une angle deThe abutment of two profile ends can be used to form a frame for example, intended in particular for the manufacture of insulating glazing. The hollow ends 2 and 3 of the profile can be closed over their entire periphery, or not. In the latter case (Figure 4), the profile end, 2 for example, is at least suitable for holding the connector 1 in the inserted position, that is to say against the side walls 2a of the profile end and against returns 2b of said side walls, the face 12 of the connector resting on these returns. The connection using the connector 1 of the invention is carried out as follows. The support piece 16 of the connector is positioned on the middle part 11a of the connector so that the lug 18a is housed in the recess 18b in the pushed position, the lug protruding from the face 12 of the connector. The connector 1 is inserted by one of its ends into the hollow part of one of the profile ends without necessarily, the connector being pressed down to the level of the sealing means 15. The second profile end is then attached around the opposite free end of the connector. By establishing a pushing force on each of the profile ends 2 and 3, these ends are brought together until their abutment is obtained at a stop 19 arranged on each of the walls 13 and 14 of the connector and in the middle of the body 10, the sealing means 15 being distributed on each side of these stops. When the ends 2 and 3 are brought together, the faces of the internal walls 20b and 30b of the profile ends come into contact with the lug 18a projecting relative to the face 12 of the connector, which exerts a pushing force against the protruding lug and then compresses the sealing means 15, disposed opposite the lug, against the opposite face 20a, 30a of the internal walls 20, and 30 of the profile ends. The junction 4 is thus sealed at at least one of the faces and the corresponding lateral edges of the internal walls of each of the ends 2 and 3 of the profile. The exemplary embodiment given above of the connector comprises, as already explained, a flat patch of sealing material combined with a pusher system to exert a compressive force when the connector is inserted into the ends of the profile. In another exemplary embodiment, rather than having such a combination, it is possible to envisage, in order to exert such a compressive force, a suitable form of the sealing means. Thus a form of concave section (FIG. 5a), or a form of conical section with a flat top (FIG. 5b), the width of the curvature or of the flat top being at least substantially greater than the width of the junction gap. 4, would be suitable. The height of the sealing means is adapted so as to obtain an easy insertion of the connector into the profile ends and to allow the abutment of the two profile ends while ensuring compression of said means against the walls of the profile ends when those -these are abutted. Of course, in this embodiment, the support part 16 is an integral part of the body of the connector, it does not need to be made mobile. The above description was made for a connection of two profile ends positioned in the same plane. On the same principle, a corner connector can be made to connect two profile ends positioned at an abutment angle. Figure 6a schematically illustrates the connector 1 before mounting. It has two wings 10a and 10b making an angle equivalent to the angle with which one wishes to connect the ends of profile 2 and 3 (here an angle of
90°). La face 11a des ailes comportent les moyens d'étanchéité 15 qui sont également disposés au niveau de l'angle 10c du connecteur. Et sur la face opposées 12 des ailes respectives 10a et 10b ainsi qu'au travers desdites ailes sont aménagés deux systèmes de poussoirs respectifs 18. Après montage, tel qu'illustré sur la figure 6b, seuls sont visibles au niveau de l'angle les moyens d'étanchéité 15. Des tests comparatifs de durabilité d'étanchéité aux gaz de vitrages isolants selon la norme NFP 78451 ont été réalisés sur des extrémités de profilé raccordées respectivement avec un connecteur classique du type celui décrit dans la demande EP 0 283 689 (nommé C1), avec ce même connecteur associé à un joint supplémentaire de butyl (nommé C2), et avec le connecteur de l'invention (nommé C3), ces connecteurs servant à réaliser les cadres des vitrages isolants. Les mesures illustrées sur la figure 7 montrent qu'au cours du temps, il reste en moyenne encore 81 % du gaz contenu dans le vitrage isolant avec le connecteur de l'invention C3 et que ce mode d'étanchéité est aussi performant, voire meilleur que celui avec un connecteur classique auquel est ajouté un joint de butyl (C2) pour lequel il reste 80% du gaz, alors qu'en moyenne il ne rest plus que 74% du gaz avec un connecteur classique sans apport supplémentaire de butyl (C1). 90 °). The face 11a of the wings comprises the sealing means 15 which are also arranged at the angle 10c of the connector. And on the opposite face 12 of the respective wings 10a and 10b as well as through the said wings are arranged two respective push-button systems 18. After assembly, as illustrated in FIG. 6b, only are visible at the angle sealing means 15. Comparative tests of gas-tightness durability of insulating glazing according to standard NFP 78451 were carried out on profile ends connected respectively with a conventional connector of the type described in application EP 0 283 689 ( named C1), with this same connector associated with an additional butyl gasket (named C2), and with the connector of the invention (named C3), these connectors serving to make the frames of insulating glazing. The measurements illustrated in FIG. 7 show that over time, there remains on average still 81% of the gas contained in the insulating glazing with the connector of the invention C3 and that this sealing mode is as efficient, or even better. than that with a conventional connector to which is added a butyl gasket (C2) for which 80% of the gas remains, while on average there remains only 74% of the gas with a conventional connector without additional intake of butyl (C1 ).
