Description

La présente invention concerne un nouveau joint auto-adhésif pour feuillure, destiné à améliorer l'étanchéité des portes et fenêtres des bâtiments, notamment dans le cas de rénovation ou d'amélioration des éléments existants.The present invention relates to a new self-adhesive seal for rebate, intended to improve the tightness of doors and windows of buildings, especially in the case of renovation or improvement of existing elements.

ART ANTERIEURPRIOR ART

Si les portes et fenêtres de fabrication industrielle récente sont de plus en plus fréquemment fournies avec un joint souple assurant l'étanchéité entre l'ouvrant et le dormant, on trouve très souvent dans les bâtiments existants des portes ou fenêtres dont l'étanchéité est très approximative. Il s'en suit des pertes d'énergie considérables et un manque de confort dans les logements ainsi mal équipés.If the doors and windows of recent industrial manufacture are of more and more frequently supplied with a flexible seal ensuring sealing between the sash and the frame, we very often find in existing buildings doors or windows whose tightness is very approximate. It follows considerable energy losses and a lack of comfort in housing as well ill-equipped.

Pour remédier à ces défauts, il existe des joints qui peuvent être adaptés à l'huisserie pour s'intercaler entre le dormant et le battant de la porte et ainsi améliorer l'étanchéité de l'ensemble ; il peut s'agir de joints obtenus en déposant un cordon de masse polymérisable du type silicone ou acrylique par extrusion d'une cartouche, ou de joints souples préformés tels que des mousses de PVC ou de polyuréthanne ou des élastomères alvéolaires ou compacts fournis sous différents profils. Ce dernier type de joint peut être fixé sur le dormant de la porte au moyen d'agrafes ou, de préférence, au moyen d'un adhésif qui fait généralement partie intégrante du joint commercialisé. Pour l'utilisateur qui veut procéder lui-même à la réfection, les joints souples en élastomère pourvus d'une bande d'adhésif sensible à la pression sont assez faciles à mettre en place et ne nécessitent pas de précautions importantes, à l'inverse des joints obtenus à partir d'une cartouche de mastic à base de silicones.To remedy these faults, there are seals which can be adapted to the frame to be inserted between the frame and the door leaf and thus improving the tightness of the assembly; these can be seals obtained in depositing a bead of polymerizable mass of silicone or acrylic type by extrusion of a cartridge, or of preformed flexible seals such as foams PVC or polyurethane or cellular or compact elastomers provided under different profiles. This last type of seal can be fixed on the frame the door by means of staples or, preferably, by means of an adhesive which makes generally an integral part of the marketed joint. For the user who wants repair itself, the flexible elastomer seals provided with a pressure sensitive tape are fairly easy to apply and do not do not require any significant precautions, unlike seals obtained from a silicone-based sealant cartridge.

Parmi les produits connus, on peut également citer les joints en V formés d'une bande de métal ou de matière plastique pliée en V et fixée au dormant par l'une des faces du dièdre, l'autre partie restant élastiquement déformable pour s'appliquer contre la porte lorsque celle-ci est fermée. De façon analogue aux joints en mousse ou en élastomère alvéolaire, les joints en V sont de préférence fixés au moyen d'un adhésif sensible à la pression.Among the known products, we can also cite V-joints formed of a metal or plastic band bent in V and fixed to the dormant by one of the dihedral faces, the other part remaining elastically deformable to be applied against the door when it is closed. Of similar to foam or cellular elastomer seals, V-seals are preferably attached with a pressure sensitive adhesive.

Ces différents joints doivent cependant toujours travailler en compression et ne supportent pas les contraintes en cisaillement : il est donc impératif, lors de la mise en place du joint sur le dormant, de veiller à ce que le joint soit placé de telle manière que l'ouvrant vienne comprimer le joint lors de la fermeture et non pas le cisailler. Dans le cas d'une porte classique articulée sur des gonds, la pose des joints devra donc être faite comme représenté sur la figure 4, c'est à dire différemment selon que l'on est côté gonds ou côté serrure : ce n'est que dans ces conditions que les joints classiques peuvent assurer leur fonction durablement. Or il est fréquent que l'utilisateur ne prenne pas la précaution de respecter les indications de pose préconisées et que le joint soit posé de façon analogue tout autour de la porte. Il s'en suit généralement un cisaillement du joint posé sur le dormant portant les gonds, qui se traduit ensuite par un décollement du joint, un défaut d'étanchéité et finalement l'insatisfaction de l'utilisateur.These different joints must however always work in compression and do not support shear stress: it is therefore imperative, when installing the seal on the frame, to ensure that the seal is placed in such a way that the opening squeezes the seal during closing and not shearing it. In the case of a traditional hinged door on hinges, the installation of the joints must therefore be made as shown on the Figure 4, that is to say differently depending on whether one is hinge side or side lock: it is only under these conditions that conventional seals can ensure their long-term function. However, it is frequent that the user does not take not take the precaution of respecting the recommended installation instructions and that the joint be placed similarly around the door. It usually follows shear of the joint placed on the frame bearing the hinges, which then results by a detachment of the joint, a leakage and finally dissatisfaction of the user.

On connaít également des joints notamment utilisés dans l'étanchéité des portières d'automobiles, et décrits par exemple dans le document GB 2 036 840, lesdits joints présentant une partie cylindrique, susceptible de s'écraser entre la feuillure et la portière, reliée à une base profilée et pourvue sur l'une ou les deux faces planes de la base d'une couche de liaison adhésive ou magnétique : la pratique montre cependant que la fixation avec une seule face adhésivée procure dans certains cas une liaison insuffisante et que la mise en place du joint, lorsque les deux faces sont adhésivées, est extrêmement délicate. Par ailleurs, la fixation par les moyens magnétiques n'est pas possible sur des huisseries en bois ou en aluminium.We also know seals used in particular in sealing car doors, and described for example in the document GB 2,036,840, said seals having a cylindrical part, capable of crash between the rebate and the door, connected to a profiled base and provided on one or both flat faces of the base of an adhesive bonding layer or magnetic: practice shows, however, that fixing with only one side Adhesive provides in some cases an insufficient bond and that the implementation place of the joint, when the two faces are adhesive, is extremely delicate. Furthermore, fixing by magnetic means is not possible on wooden or aluminum frames.

Dans FR 1 151 433 il est décrit un joint dont l'une des faces planes est recouverte d'une couche de substance adhésive et d'un protecteur, pour être fixé sur l'une des parties planes de l'huisserie : il faut cependant prendre soin, au moment de la pose, de placer la face adhésive sur la face comprimée par le joint afin d'éviter un arrachement par cisaillement.In FR 1 151 433 a joint is described, one of the planar faces of which is covered with a layer of adhesive substance and a protector, to be fixed to one of the flat parts of the frame: care must be taken, when laying, place the adhesive side on the side compressed by the joint to prevent shearing.

BUT DE L'INVENTIONPURPOSE OF THE INVENTION

La présente invention vise à fournir un joint auto-adhésif pour feuillure, utile pour améliorer l'étanchéité des portes et ouvertures, et qui puisse être posé sans risque d'erreur tout autour du dormant de ladite ouverture.The present invention aims to provide a self-adhesive seal for rebate, useful for improving the tightness of doors and openings, and which can be installed without risk of error all around the frame of said opening.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Selon l'invention, on propose un joint auto-adhésif souple présentant les caractéristiques de la revendication 1 annexée, dont le préambule est formé sur le document GB 2 036 840. According to the invention, a flexible self-adhesive seal is proposed. having the features of claim 1 attached, the preamble of which is formed on the document GB 2,036,840.

Selon un autre aspect de l'invention, la lèvre souple peut être de simple épaisseur, ou présenter, sur au moins une partie, une section creuse.According to another aspect of the invention, the flexible lip can be single thickness, or have, on at least a part, a hollow section.

Selon un mode préféré, le joint auto-adhésif comprend également un protecteur temporaire anti-adhérent enlevable recouvrant le cordon auto-adhésif.According to a preferred embodiment, the self-adhesive seal also comprises a removable non-stick temporary protector covering the self-adhesive bead.

DESCRIPTIONDESCRIPTION

Comme indiqué précédemment, l'invention a pour objet de fournir un joint souple auto-adhésif adapté et profilé pour être fixé dans l'angle d'une feuillure ou de l'huisserie fixe recevant la porte ou la fenêtre dont on souhaite améliorer l'étanchéité : un tel joint présente ainsi, après fixation, une lèvre souple orientée sensiblement selon la bissectrice de l'angle de la feuillure et peut assurer sa fonction correctement et de façon identique lorsque le battant de l'ouverture se présente tangentiellement à l'un ou l'autre des deux côtés de l'angle de feuillure de l'huisserie.As indicated above, the object of the invention is to provide a flexible self-adhesive seal adapted and profiled to be fixed in the corner of a rebate or fixed frame receiving the door or window of which one wishes improve sealing: such a seal thus has, after fixing, a lip flexible oriented substantially along the bisector of the rebate angle and can perform its function correctly and identically when the leaf the opening is presented tangentially to one or the other of the two sides of the frame rebate angle.

Other advantages and characteristics of the present invention will emerge more clearly on reading the description of several embodiments as well as the appended drawings in which:

Le joint auto-adhésif selon la présente invention est destiné à être disposé dans une feuillure pour assurer une fonction d'étanchéité, l'angle de la feuillure pouvant varier entre certaines limites. D'ordinaire, l'angle de la feuillure est droit.The self-adhesive seal according to the present invention is intended to be arranged in a rebate to ensure a sealing function, the angle of the rebate may vary between certain limits. Usually the angle of the rebate is straight.

Le joint auto-adhésif selon l'invention comprend une embase 1 dotée de deux ailes latérales 2 qui forment entre elles un angle sensiblement égal à celui de la feuillure sur laquelle ledit joint est déposé. Sur la figure 1 l'angle de la feuillure est de 90° et, en conséquence, les ailes latérales 2a, 2b sont perpendiculaires l'une à l'autre pour former également un angle de 90°. Un cordon adhésif 3 est disposé sur un côté 4 de l'embase 1 qui est solidaire par son autre côté 5 d'une lèvre souple 6 située sensiblement dans le plan de la bissectrice de l'angle formé par lesdites ailes latérales 2a, 2b. Dans les exemples des figures, la lèvre souple 6 est inclinée de 45° environ par rapport aux ailes latérales 2a, 2b, l'embase 1 étant, de préférence, perpendiculaire à la lèvre souple 6.The self-adhesive seal according to the invention comprises a base 1 provided of two lateral wings 2 which form an angle between them substantially equal to that of the rebate on which said seal is deposited. In Figure 1 the angle of the rabbet is 90 ° and, consequently, the lateral wings 2a, 2b are perpendicular to each other to also form an angle of 90 °. A adhesive bead 3 is arranged on one side 4 of the base 1 which is integral by its other side 5 of a flexible lip 6 located substantially in the plane of the bisector of the angle formed by said lateral wings 2a, 2b. In the examples of the figures, the flexible lip 6 is inclined by about 45 ° relative to the wings side 2a, 2b, the base 1 preferably being perpendicular to the lip flexible 6.

Le cordon adhésif 3 présente une forme cylindrique mais pourrait présenter tout autre forme telle que demi-cylindrique, comme cela est représenté sur la figure 2, et il est recouvert d'un protecteur 7 enlevable au moment de la mise en place du joint dans la feuillure de réception 8 (figure 3), le protecteur 7 étant, par exemple, constitué par un film anti-adhérent.The adhesive bead 3 has a cylindrical shape but could have any other shape such as semi-cylindrical, as shown in FIG. 2, and it is covered with a protector 7 which can be removed at the time of fitting of the seal in the receiving rabbet 8 (FIG. 3), the protector 7 being, for example, constituted by a non-stick film.

Dans le mode de réalisation représenté sur la figure 1, la lèvre souple 6 est pleine et constitue une partie intégrante de l'embase 1, alors que dans le mode de réalisation de la figure 2, la lèvre souple 6 comprend une ouverture 9 destinée à améliorer la déformation de la lèvre 6 au niveau de l'articulation avec l'embase 1.In the embodiment shown in Figure 1, the lip flexible 6 is full and constitutes an integral part of the base 1, while in the embodiment of Figure 2, the flexible lip 6 comprises a opening 9 intended to improve the deformation of the lip 6 at the level of the joint with the base 1.

Selon le mode de réalisation de la figure 3, la lèvre souple 6 est creuse sur toute sa longueur et se présente sous la forme d'une section tubulaire. Bien évidemment, on pourrait utiliser une lèvre souple qui serait creuse en partie et pleine sur le reste de sa longueur ou encore d'autres formes.According to the embodiment of Figure 3, the flexible lip 6 is hollow over its entire length and is in the form of a tubular section. Obviously, we could use a flexible lip which would be partially hollow and full over the rest of its length or other shapes.

La mise en place du joint auto-adhésif selon la présente invention est très schématiquement représentée sur la figure 5.The establishment of the self-adhesive seal according to the present invention is very schematically represented in FIG. 5.

Le joint de l'art antérieur représenté sur la figure 4 exige une pose différente selon qu'on se trouve sur le montant portant les paumelles ou sur le montant côté serrure. Si ces consignes de pose ne sont pas respectées le joint est soumis à des contraintes latérales qui conduisent à un décollement ou à un sectionnement. Au contraire, le joint selon la présente invention est déposé de façon identique quelle que soit la partie de l'huisserie recevant le joint, ce qui facilite la pose et élimine le risque d'erreur. Lorsque le joint est posé dans la feuillure du dormant 10 recevant l'extrémité 11 d'un battant 12, la lèvre souple 6 est pliée vers le bas, alors que du côté 13 des gonds 14, la lèvre souple 6 est pliée vers le haut. De ce fait, il ne se produit aucun cisaillement du joint et le risque de détérioration est donc éliminé.The seal of the prior art shown in Figure 4 requires installation different depending on whether you are on the amount carrying the hinges or on the amount on the lock side. If these installation instructions are not observed, the joint is subject to lateral stresses which lead to detachment or sectioning. On the contrary, the seal according to the present invention is removed from identically regardless of the part of the frame receiving the seal, which facilitates installation and eliminates the risk of error. When the gasket is installed in the rebate of the frame 10 receiving the end 11 of a leaf 12, the flexible lip 6 is folded down, while on the side 13 of the hinges 14, the flexible lip 6 is folded up. As a result, there is no shearing of the joint and the risk of deterioration is therefore eliminated.

Le profil particulier de l'embase du joint selon l'invention permet d'obtenir à la fois une mise en place facile du joint avec un effet autocentreur et une bonne orientation de la lèvre souple : selon la figure 1, les ailes 2a et 2b de l'embase, qui ne sont pas adhésivées, ont pour fonction de guider le joint jusque dans l'angle de l'huisserie puis de maintenir la lèvre souple 6 dans la position de la bissectrice de l'angle de la feuillure, c'est à dire, d'une façon générale, avec un angle de 45 ° par rapport à chacune des faces de la feuillure, dès lors que le cordon adhésif assure la liaison du joint avec la feuillure.The particular profile of the base of the seal according to the invention allows to obtain both an easy positioning of the seal with a self-centering effect and good orientation of the flexible lip: according to FIG. 1, the wings 2a and 2b of the base, which are not adhesive-coated, have the function of guiding the seal as far as in the angle of the frame and then maintain the flexible lip 6 in the position of the bisector of the angle of the rebate, that is to say, generally, with an angle of 45 ° with respect to each of the faces of the rebate, as soon as the adhesive bead ensures the connection of the joint with the rebate.

La réalisation pratique du joint fait appel à des techniques et matériaux connus ; le joint est obtenu de préférence par extrusion d'un matériau thermoplastique et/ou caoutchoutique tel que par exemple des caoutchoucs de synthèse à base d'EPDM éventuellement formulé avec du polypropylène, ou à base d'élastomères silicone ou encore à base de triblocs SIS, SBS ou SEBS. On peut utiliser tout type de matériau souple et élastique, compact ou alvéolaire.The practical realization of the joint calls upon techniques and known materials; the joint is preferably obtained by extruding a material thermoplastic and / or rubber such as for example rubbers synthesis based on EPDM possibly formulated with polypropylene, or based on silicone elastomers or based on SIS, SBS or SEBS triblocks. We can use any type of flexible and elastic material, compact or cellular.

Le cordon adhésif 3 peut être déposé directement sur l'embase du joint ou, en fonction de l'élastomère utilisé, après enduction d'un primaire qui améliore la liaison entre l'élastomère et la masse adhésive.The adhesive bead 3 can be placed directly on the base of the joint or, depending on the elastomer used, after coating with a primer which improves the bond between the elastomer and the adhesive mass.

Le cordon adhésif 3 sensible à la pression peut être par exemple à base d'une formulation hot-melt comprenant des élastomères de type tribloc tels que les SIS, SBS ou SEBS, associés à des résines tackifiantes tels que des résines terpéniques ou des résines de colophane. On peut également utiliser d'autres formulations auto-adhésives par exemple à base de caoutchouc butyl, en choisissant de préférence des masses adhésives cohésives et conformables. Les cordons adhésifs sont généralement obtenus par extrusion de la masse malaxée à chaud et peuvent être extrudés de façon compacte ou de façon moussée à l'aide d'azote. Le cordon adhésif 3, déposé sur l'embase, peut présenter une section cylindrique (comme représenté sur la figure 1) ou une section en forme de demi-cylindre avec, dans ce cas, la face plane appuyée contre l'embase, comme représenté sur la figure 2.The pressure-sensitive adhesive bead 3 may for example be base of a hot-melt formulation comprising triblock type elastomers such as SIS, SBS or SEBS, associated with tackifying resins such as terpene resins or rosin resins. We can also use other self-adhesive formulations, for example based on butyl rubber, in preferably choosing cohesive and conformable adhesive masses. The adhesive cords are generally obtained by extruding the kneaded mass to hot and can be extruded compactly or foamed using nitrogen. The adhesive bead 3, deposited on the base, may have a section cylindrical (as shown in Figure 1) or a half-cylinder shaped section with, in this case, the flat face pressed against the base, as shown in figure 2.

Le film protecteur temporaire peut être un papier siliconé ou un film en polyester ou polyéthylène anti-adhérent.The temporary protective film can be a silicone paper or a film polyester or polyethylene non-stick.

Exemple de réalisationExample of realization

Un joint, dont la forme en section est représentée par la figure 3, est extrudé à chaud à partir d'une masse d'élastomères thermoplastiques à base d'EPDM et de polypropylène (commercialisé sous la marque SANTOPRENE) pour obtenir un joint continu dont la hauteur comprise entre la base et l'extrémité libre de la lèvre est d'environ 11 mm.A joint, the cross-sectional shape of which is shown in FIG. 3, is hot extruded from a mass of thermoplastic elastomers based EPDM and polypropylene (sold under the brand SANTOPRENE) to obtain a continuous joint whose height between the base and the free end of the lip is approximately 11 mm.

On dépose ensuite sur la face centrale de l'embase un cordon de masse adhésive à base de caoutchouc butyl (le diamètre du cordon est d'environ 2 mm) et on recouvre ce cordon adhésif au moyen d'un protecteur en papier siliconé de largeur environ 4 mm.A bead of wire is then placed on the central face of the base. butyl rubber-based adhesive (the bead diameter is approximately 2 mm) and cover this adhesive bead with a paper protector silicone about 4 mm wide.

Un tel joint convient bien pour assurer l'étanchéité de portes ou de fenêtres dont l'espace à combler entre le dormant et l'ouvrant peut varier de 2 à 8 mm : le joint doit être posé dans l'angle de la feuillure de l'huisserie, les deux ailes 2a et 2b de l'embase étant chacune en appui sur les faces de la feuillure. Cette forme spécifique de l'embase permet au cordon adhésif de s'insérer parfaitement dans l'angle de la feuillure et d'obtenir une position du joint parfaitement centrée. La figure 6 représente la flexion du joint lors de la fermeture de l'ouvrant, cette flexion se faisant de part ou d'autre du plan bissecteur selon que le joint se trouve d'un côté ou de l'autre du dormant.Such a seal is well suited for sealing doors or windows whose space to be filled between the frame and the sash can vary from 2 to 8 mm: the gasket must be placed in the corner of the door frame, both wings 2a and 2b of the base each bearing on the faces of the rebate. This specific shape of the base allows the adhesive bead to be inserted perfectly in the angle of the rebate and to obtain a position of the joint perfectly centered. Figure 6 shows the bending of the joint during the closing of the opening, this bending being made on either side of the plane bisector depending on whether the seal is on one side or the other of the frame.

Ainsi, bien qu'ayant été mis en place de la même façon sur tout le pourtour du dormant, le joint assure sa fonction correctement et durablement en adaptant sa déformation sur chacun des côtés de l'ouverture.So, although having been set up in the same way on all around the frame, the seal ensures its function correctly and durably by adapting its deformation on each side of the opening.

L'exemple décrit ci-dessus est particulièrement adapté aux travaux de rénovation de portes et fenêtres dans les bâtiments d'habitation. On peut également, sans sortir du domaine de l'invention, réaliser des joints auto-adhésifs adaptables pour des ouvertures de dimensions différentes ou appartenant à des secteurs d'activités autres que le bâtiment.The example described above is particularly suitable for work renovation of doors and windows in residential buildings. We can also, without departing from the scope of the invention, making self-adhesive seals adaptable for openings of different dimensions or belonging to sectors of activity other than construction.
