Abstract

A door or window frame formed using sections (2) made of a synthetic material has at least one upright (3) which subdivides the frame and is welded between the arms of the frame (1) by means of mitred joints (5) to form a corner. In order to avoid the arms of the frame (1) becoming excessively weakened as a result of the large notches cut into the mitred-joint area, these mitred joints (5) are truncated by means of a front face (7) which extends transversely across the tip of the two mitred surfaces (6) extending obliquely towards each other.

Description

Cadre de fenêtre ou de porte réalisé en profilés en matière
synthétique
L'invention est relative à un cadre de fenêtre ou de porte réalisé en profilés en matière synthétique, au moins un montant, subdivisant le cadre, étant soudé entre les branches de cadre, ainsi qu'un dispositif de soudage, pour effectuer le soudage d'assemblage en T de profilés en matière synthétique pour de tels cadres de fenêtre ou porte.Window or door frame made of material profiles
synthetic
The invention relates to a window or door frame made of plastic profiles, at least one upright, dividing the frame, being welded between the frame branches, as well as a welding device, for carrying out the welding of 'T-shaped assembly of plastic profiles for such window or door frames.

Les cadres en matière synthétique pour fenêtres ou portes ou analogues sont usuellement fabriqués par soudage d'assemblage de profilés en matière synthétique, des montants, subdivisant le cadre, servant de dormant, d'imposte, de poteau ou de meneau, étant soudés dans les branches de cadre, en formant également des joints à onglets. Ces joints à onglet ont jusqu'ici une forme en coin avec une pointe de coin d'un angle de 900 et, pour ce qui concerne le soudage, les montants sont appliqués, par leur face frontale en forme de coin, sur une encoche en V, correspondante, de la branche de cadre. Afin de faire s'adapter avec précision les contours des profilés de branches et de montants après soudage, les joints à onglet sont en général symétriques par rapport au milieu du montant, de sorte que ce joint à onglet fait, dans la direction longitudinale, la moitié de la largeur du profilé des montants, du fait des faces d'onglet, s'étendant à 450 par rapport à la direction longitudinale des montants. Du fait qu'également lencochage réalisé dans les branches du cadre doit présenter une taille adaptée aux dimensions du profilé du montant, on arrive de ce fait à une découpe d'encoche relativement profonde dans le profilé en matière synthétique de 'a branche du cadre, ce qui diminue la résistance de ce profilé et rend son maniement plus difficile dans le processus de soudage, qui est délicat. Si, pour augmenter la surface vitrée, on choisit un profilé de cadre vraiment étroit, d'une part, et que, pour des raisons esthétiques, on choisit, d'autre part, un profilé de montant large en comparaison, ces joints à onglet connus peuvent par conséquent conduire à des difficultés, du fait que les découpes d'encoche d'une profondeur correspondante ouvrent alors également sur une certaine distance les chambres principales des profilés et conduisent à un affaiblissement bien dangereux des profilés. Dans un cas extrême, on a même une séparation du profilé, ce qui par exemple se produit en cas de soudage croisé de deux montants soudés en des points d'application, mutuellement opposés du profilé de branche. En outre, du fait de la profondeur de l'encochage, il est souvent également nécessaire d'entailler les profilés de renforcement, insérés dans les chambres principales du profilé de branche, voire si l'on ne doit pas en plus les introduire, dans une phase opératoire propre, entre le chauffage des faces à souder et le pressage d'assemblage des points de joints à souder de ce profilé de renforcement, ce qui fait qu'il se produit surtout une diminution résiduelle de la résistance du cadre. Plastic frames for windows or doors or the like are usually produced by welding assembly of plastic profiles, uprights, dividing the frame, serving as a frame, transom, pole or mullion, being welded in frame branches, also forming miter joints. These miter joints have so far had a wedge shape with a corner tip with an angle of 900 and, as regards welding, the uprights are applied, by their wedge-shaped front face, to a notch in V, corresponding, of the frame branch. In order to precisely adapt the contours of the branch and upright profiles after welding, the miter joints are generally symmetrical with respect to the middle of the upright, so that this miter joint makes, in the longitudinal direction, the half the width of the profile of the uprights, due to the miter faces, extending to 450 relative to the longitudinal direction of the uprights. Because also the notching produced in the branches of the frame must have a size adapted to the dimensions of the profile of the upright, this leads to a relatively deep notch cut in the plastic profile of the branch of the frame, which decreases the resistance of this profile and makes its handling more difficult in the welding process, which is delicate. If, to increase the glass surface, we choose a really narrow frame profile, on the one hand, and if, for aesthetic reasons, we choose, on the other hand, a wide stud profile in comparison, these miter joints known can therefore lead to difficulties, because the notch cuts of a corresponding depth then also open over a certain distance the main chambers of the profiles and lead to a very dangerous weakening of the profiles. In an extreme case, there is even a separation of the profile, which for example occurs in the case of cross welding of two uprights welded at points of application, mutually opposite of the branch profile. In addition, due to the depth of the notching, it is often also necessary to cut the reinforcing profiles, inserted in the main chambers of the branch profile, or even if they should not be introduced in addition, in a clean operating phase, between the heating of the faces to be welded and the assembly pressing of the points of joints to be welded to this reinforcement profile, which means that there is above all a residual reduction in the resistance of the frame.

C'est pourquoi l'invention a pour but d'éliminer ce défaut et de créer un cadre de fenêtre ou de porte du type évoqué au début, pouvant être assemblé par soudage à partir de profilés les plus différents, ceci parfaitement et sans difficulté, de manière particulièrement simple et appropriée. This is why the invention aims to eliminate this defect and create a window or door frame of the type mentioned at the start, which can be assembled by welding from the most different profiles, this perfectly and without difficulty, in a particularly simple and appropriate way.

En outre, il doit être indiqué un dispositif de soudage pour effectuer une fabrication rationnelle de tels cadres de fe nêtre ou de porte. A laide de cette configuration en onglet on doit, par rapport au joint à onglet classique et pratiquement sans court supplémentaire, diminuer la profondeur du joint à onglet et la réduire à la valeur souhaitée, sans mettre en danger alors l'adaptation précise mutuelle des profilés soudés ensemble, ni nuire à la résistance de la liaison soudée elle même. Du fait du troncage du joint à onglet, on évite d'avoir une trop grande profondeur d'encoche du point d'application dans le profilé de branche, de sorte qu'on n'a pas non plus à craindre de plus grandes pertes de stabilité de ces profilés de branche et que, concernant le maniement des profilés pendant le processus de soudage, il n'est pas nécessaire de prendre spécialement en considération une telle perte de résistance des profilés. L'utilisation faite de joints à onglet tronqués rend en outre inutile, en cas de liaisons croisées, d'opérer une séparation complète du profilé de branche qui est continu et lencochage peut être de dimensions telles que des profilés de renforcement des profilés de branche restent intouchés ou, tout au plus, évidés d'une façon insignifiante dans la zone des points d'application. Enfin, mais pas à moindre titre, il est possible, sans problème, d'épargner, lors de l'application, un encochage aux montants des planches d'appui éventuellement intégrées dans la branche de cadre, ou d'autres éléments en saillie.In addition, a welding device must be indicated in order to carry out rational production of such window or door frames. With the help of this miter configuration, the depth of the miter joint must be reduced and reduced to the desired value, compared to the conventional miter joint and practically without additional short, without jeopardizing the mutual mutual adaptation of the profiles. welded together, nor adversely affect the strength of the welded joint itself. Due to the truncation of the miter joint, one avoids having too great a notch depth of the point of application in the branch profile, so that one does not have to fear greater losses of stability of these branch profiles and that, with regard to the handling of the profiles during the welding process, it is not necessary to take special account of such a loss of strength of the profiles. The use made of truncated miter joints also makes it unnecessary, in the case of cross links, to carry out a complete separation of the branch profile which is continuous and the notching can be of dimensions such that reinforcing profiles of the branch profiles remain untouched or, at most, hollowed out insignificantly in the area of the application points. Finally, but not to a lesser extent, it is possible, without problem, to save, during application, a notching in the uprights of the support boards possibly integrated in the frame branch, or other projecting elements.

Pour souder des profilés en matière synthétique, il existe des dispositifs de soudure les pus différents, à une ou plusieurs têtes, dispositifs dans lesquels on peut souder ensemble deux profilés par tête. A cette fin, les profilés sont bloqués par serrage dans des ensembles de serrage de profilé et sont pressés, au moyen d'un déplacement correspondant de ces ensembles de serrage, avec les faces de soudage, sur un miroir de soudage, inséré entre ceux-ci, jusqu'à fusion et ensuite, après enlèvement du miroir de soudage, on comprime les faces de soudage ayant été plastifiées. Dans le cas d'un tel dispositif de soudage, pour pouvoir souder correctement des profilés en matière synthétique servant de branches et de montants de cadre, le miroir de soudage présente une section transversale en forme d'auge, la face frontale d'un premier profilé en matière synthétique ayant une forme en coin, tronquée, correspondant au contour intérieur de cette section transversale, et le point d'application de l'autre profilé en matière synthétique présentant une forme en auge, correspondant au point d'application de l'autre profilé en matière synthétique. Un tel miroir de soudage peut être mis en oeuvre sans grands travaux de conversion, pratiquement pour tout dispositif de soudage approprié, de sorte qu'on peut également fabriquer des joints à onglet selon l'invention avec de tels dispositifs de soudage usuels. To weld plastic profiles, there are different welding devices, with one or more heads, devices in which two profiles can be welded together. To this end, the profiles are locked by clamping in profile clamping assemblies and are pressed, by means of a corresponding displacement of these clamping assemblies, with the welding faces, on a welding mirror, inserted between them ci, until fusion and then, after removal of the welding mirror, the welding faces which have been plasticized are compressed. In the case of such a welding device, in order to be able to correctly weld plastic profiles serving as branches and frame uprights, the welding mirror has a trough-shaped cross section, the front face of a first plastic profile having a truncated wedge shape, corresponding to the internal contour of this cross section, and the point of application of the other plastic profile having a trough shape, corresponding to the point of application of the other plastic profile. Such a welding mirror can be implemented without major conversion work, practically for any suitable welding device, so that one can also manufacture miter seals according to the invention with such usual welding devices.

D'autres caractéristiques et avantages de l'objet de l'invention ressortiront de la description qui va suivre en regard des dessins annexés qui représentent, schématique ment et simplement à titre d'exemple, un mode de réalisation préféré. Other characteristics and advantages of the subject of the invention will emerge from the description which follows with reference to the appended drawings which show, schematically and simply by way of example, a preferred embodiment.

Sur ces dessins
Les figures 1 et 2, respectivement 3 et 4, représentent deux
exemples de réalisation de joints à onglet d'un
cadre de fenêtre selon l'invention, chaque fois
en vue de dessus et en vue latérale, et la figure 5 illustre le principe de fonctionnement d'un
dispositif de soudage selon l'invention, pour
souder en vue d'assemblage, en T, des profilés en
matière synthétique.On these drawings
Figures 1 and 2, respectively 3 and 4, represent two
examples of miter joints
window frame according to the invention, each time
in top view and in side view, and Figure 5 illustrates the principle of operation of a
welding device according to the invention, for
weld for assembly, in T, of the profiles in
synthetic material.

Un cadre de fenêtre, représenté seulement par une partie d'une branche de cadre 1, est composé de profilés en matière synthétique 2 individuels, assemblés par soudage, et est subdivisé au moyen d'un montant 3, servant de dormant, d'imposte ou de meneau, également composé d'un profilé en matière synthétique 4. Ce montant i est soudé dans la branche de cadre 1, par l'intermédiaire d'un joint à onglet 5, présentant deux faces d'onglet 6, orientées obliquement en direction lune de l'autre, et une face frontale 7, s'étendant transversalement dans la zone de pointe entre ces faces don- glet i et donnant une forme en coin tronquée. A window frame, represented only by part of a frame branch 1, is made up of individual plastic profiles 2, assembled by welding, and is subdivided by means of an upright 3, serving as a frame, a transom or mullion, also composed of a plastic profile 4. This amount i is welded in the frame branch 1, by means of a miter joint 5, having two miter faces 6, oriented obliquely in direction of the moon on the other, and a front face 7, extending transversely in the point zone between these face dice i and giving a truncated corner shape.

Le plus souvent, le joint à onglet a est, comme indiqué dans l'exemple de réalisation des figures 1 et 2, symétrique par rapport au plan médian longitudinal du profilé en matière synthétique 4 des montants 3, avec des faces d'onglet orientés à 450 obliquement, et une face frontale 7 s'étendant perpendiculairement par rapport au plan médian longitudinal, cependant, le joint à onglet a, comme représenté dans l'exemple de réalisation des figures 3 et 4, dans le cas d'un appendice de montant X ayant une allure biaise, peut être également de réalisation asymétrique sur la branche de cadre 1., les faces d'onglet a s'étendant alors de manière correspondante symétriquement par rapport aux angles intérieurs ou extérieurs, entre la branche de cadre et le montant et la face frontale 7a s'étendant parallèlement à l'axe de la branche de cadre. Most often, the miter joint a is, as indicated in the embodiment of Figures 1 and 2, symmetrical with respect to the longitudinal median plane of the plastic profile 4 of the uprights 3, with miter faces oriented at 450 obliquely, and a front face 7 extending perpendicularly to the longitudinal median plane, however, the miter joint a, as shown in the embodiment of Figures 3 and 4, in the case of a stud appendage X having a biased appearance, can also be asymmetrical on the frame branch 1., the miter faces a then extending correspondingly symmetrically with respect to the interior or exterior angles, between the frame branch and the upright and the front face 7a extending parallel to the axis of the frame branch.

Comme représenté sur la figure 5, lors du soudage d'assemblage en T de deux profilés 2, 4 en matière synthétique, dont l'un sert de branche de cadre et l'autre de montant, on insère un dispositif de soudage, non représenté en détail, équipé d'un miroir de soudage i, à section transversale en forme d'auge, susceptible d'être introduit entre les faces à souder devant être soudées ensemble des profilés 2, 4 en matière synthétique. Le premier profil 4 en matière synthétique, constituant le montant, présente alors une face frontale 4a avec une forme en coin adaptée au contour intérieur du miroir de soudage 8, et l'autre profilé 2 en matière synthétique, servant de branche de cadre, présente une forme en auge, adapté au contour extérieur du miroir de soudage 8, de sorte que le premier profilé 4 en matière synthétique, le miroir de soudage 8 et l'autre profilé 2 en matière synthétique sont comprimés les uns sur les autres, de façon ajustée, pour le chauffage des faces à souder, et qu'ensuite, une fois le miroir de soudage 8 enlevé, les faces frontales 4a, respectivement les points d'application 2a plastifiés des profilés 4, 2 en matière synthétique peuvent être comprimés ensemble, de façon ajustée, pour le soudage. As shown in FIG. 5, when welding the T-shaped connection of two sections 2, 4 of synthetic material, one of which serves as a frame branch and the other of the upright, a welding device is inserted, not shown in detail, equipped with a welding mirror i, with a cross section in the shape of a trough, capable of being introduced between the faces to be welded which must be welded together with profiles 2, 4 of synthetic material. The first profile 4 made of synthetic material, constituting the upright, then has a front face 4a with a wedge shape adapted to the interior contour of the welding mirror 8, and the other profile 2 made of synthetic material, serving as a frame branch, has a trough shape, adapted to the external contour of the welding mirror 8, so that the first profile 4 of synthetic material, the welding mirror 8 and the other profile 2 of synthetic material are compressed one on top of the other, so adjusted, for heating the faces to be welded, and then, once the welding mirror 8 has been removed, the front faces 4a, respectively the plasticized application points 2a of the profiles 4, 2 made of synthetic material can be compressed together, adjusted, for welding.

Le joint à onglet X, a tronqué apparu assure un soudage correct de montants 3 subdivisant des cadres, également lorsque les profilés en matière synthétique sont de dimensions différentes pour les montants et les branches de cadre, sans devoir craindre un affaiblissement indésirable des profilés en matière synthétique, du fait que les encochages sont trop grands.  The miter joint X, truncated appeared ensures correct welding of uprights 3 dividing frames, also when the plastic profiles are of different dimensions for the uprights and the branches of frame, without having to fear an undesirable weakening of the material profiles synthetic, because the notches are too large.
