Description

La présente invention concerne un procédé pour la réalisation d'un profilé composite bois-métal, ainsi que le profilé composite obtenu par la mise en oeuvre du procédé.The present invention relates to a process for producing a wood-metal composite profile, as well as the composite profile obtained by implementing the process.

Quoique non exclusivement, le profilé complexe selon l'invention est particulièrement destiné au domaine de la menuiserie en général, notamment pour la réalisation des cadres de portes, fenêtres, et analogues.Although not exclusively, the complex profile according to the invention is particularly intended for the field of carpentry in general, in particular for the production of door frames, windows, and the like.

On connaît déjà, par exemple par les documents EP-A-­0 053 104 et EP-A-0 159 458, un procédé permettant d'obtenir des profilés composite bois-métal. Un tel procédé consiste essentiellement à maintenir écartés, parallèlement l'un à l'autre, un profilé de bois et un profilé de métal, par exemple en aluminium, et à injecter entre eux un liant adhésif durcissable. On obtient alors des profilés composites à partir desquels, après des opérations de découpe, on réalise, notamment par l'intermédiaire de systèmes d'assemblage, des cadres de fenêtres ou analogues.There is already known, for example from documents EP-A-0 053 104 and EP-A-0 159 458, a method for obtaining wood-metal composite profiles. Such a method essentially consists in keeping apart, in parallel to each other, a wooden profile and a metal profile, for example aluminum, and injecting between them a curable adhesive binder. Composite profiles are then obtained from which, after cutting operations, window frames or the like are produced, in particular by means of assembly systems.

En pratique, la mise en oeuvre d'un tel procédé soulève des difficultés.In practice, the implementation of such a method raises difficulties.

Tout d'abord, il faut prévoir des dispositifs mécaniques complexes pour maintenir les profilés de bois et de métal l'un relativement à l'autre et pour délimiter transversale­ment l'espace dans lequel est injecté ledit liant adhésif. Cette difficulté est augmentée du fait qu'aucune liaison mécanique - autre que ledit liant adhésif - ne doit subsister entre lesdits profilés après leur solidarisation, notamment afin d'éviter les ponts thermiques entre eux. Si une telle liaison demeurait, il se produirait des phénomènes de condensation sur le profilé métallique entraînant rapidement une dégradation du profilé en bois par l'apparition de moisissures.First of all, it is necessary to provide complex mechanical devices to hold the profiles of wood and metal relative to one another and to delimit transversely the space in which said adhesive binder is injected. This difficulty is increased by the fact that no mechanical connection - other than said adhesive binder - must remain between said profiles after they have been joined, in particular in order to avoid thermal bridges between them. If such a bond remained, condensation phenomena would occur on the metal profile, rapidly leading to degradation of the wooden profile by the appearance of mold.

Par ailleurs, d'autres difficultés sont dues à la différence de nature (bois et métal) des profilés à assembler. Ainsi, lors du durcissement du liant adhésif, les contraintes apparaissant aux niveaux des liaisons entre le liant et les deux profilés sont différentes, de sorte que le profilé composite obtenu présente des déformations géométriques et qu'il n'est pas rigoureusement rectiligne. Pour redresser le profilé composite, on est alors amené à désolidariser par coulissement longitudinal le profil métallique du liant, ce qui permet au profilé, grâce à ses caractéristiques d'élasticité, de revenir spontanément dans son état initial. Toutefois, une telle intervention diminue considérablement les caractéristiques mécaniques du profilé composite, puisque le profilé métallique est libre en coulissement par rapport au profilé en bois, grâce à des guides coopérant avec le liant. Ainsi, les profilés de bois et de métal, formant le profilé composite, ne sont maintenus en position, lors de l'assemblage à un autre profilé composite, que par leurs faces d'extrémité biseautées qui viennent en appui contre celles dudit autre profilé complexe.In addition, other difficulties are due to the difference in nature (wood and metal) of the profiles to be assembled. Thus, during hardening of the adhesive binder, the stresses appearing at the level of the connections between the binder and the two profiles are different, so that the composite profile obtained has geometric deformations and that it is not strictly rectilinear. To straighten the composite profile, it is then necessary to separate the metal profile of the binder by longitudinal sliding, which allows the profile, thanks to its elasticity characteristics, to return spontaneously to its initial state. However, such an intervention considerably reduces the mechanical characteristics of the composite profile, since the metal profile is free to slide relative to the wooden profile, thanks to guides cooperating with the binder. Thus, the wood and metal profiles, forming the composite profile, are held in position, when assembling to another composite profile, only by their bevelled end faces which come to bear against those of said other complex profile .

La présente invention a pour objet de pallier ces inconvé­nients, et concerne un procédé de réalisation d'un profilé complexe grâce auquel les caractéristiques géométriques et mécaniques du profilé obtenu sont respectées, tout en délimitant latéralement, au moins en partie, l'espace dans lequel est introduit ledit liant adhésif durcissable.The object of the present invention is to overcome these drawbacks, and relates to a method for producing a complex profile by which the geometric and mechanical characteristics of the profile obtained are respected, while laterally delimiting, at least in part, the space in which said curable adhesive binder is introduced.

A cette fin, selon l'invention, le procédé pour la réalisa­tion d'un profilé composite bois-métal, selon lequel on dispose parallèlement l'un à l'autre un profilé de métal et un profilé de bois en les maintenant écartés et on remplit l'espace séparant lesdits profilés de métal et de bois d'un liant adhésif durcissable, est remarquable en ce que :
- dans l'un desdits profilés, on réalise un premier élément de relief longitudinal, tel qu'une rainure ou une nervure ;
- dans l'autre desdits profilés, on prévoit une aile longitudinale susceptible de recouvrir ledit espace ;
- ladite aile longitudinale compsorte à son bord libre un second élément de relief longitudinal, tel qu'une nervure ou une rainure, susceptible de coopérer avec ledit premier élément de relief longitudinal, de façon à réunir lesdits profilés de métal et de bois par emboîtement desdits premier et second éléments de relief ; et
- après durcissement dudit liant adhésif dans ledit espace, on élimine par usinage ladite aile reliant lesdits profilés.To this end, according to the invention, the method for producing a wood-metal composite profile, according to which a metal profile and a wood profile are arranged parallel to each other, keeping them apart and fills the space separating said metal and wood profiles with a curable adhesive binder, is remarkable in that:
- In one of said sections, a first longitudinal relief element is produced, such as a groove or a rib;
- In the other of said sections, there is provided a longitudinal wing capable of covering said space;
- Said longitudinal wing comprises at its free edge a second element of longitudinal relief, such as a rib or a groove, capable of cooperating with said first element of longitudinal relief, so as to join said metal and wood profiles by interlocking said first and second relief elements; and
- After hardening of said adhesive binder in said space, said wing that connects said profiles is removed by machining.

Ainsi, grâce au procédé de l'invention, on crée une liaison temporaire sur toute la longueur des profilés à assembler, qui ferme en partie ledit espace et qui est conservée jusqu'au durcissement total du liant introduit dans cet espace, de sorte que les deux profilés restent rigoureuse­ment rectilignes. Après quoi, on supprime la liaison temporaire réalisée au moyen de l'aile longitudinale pour obtenir alors un profilé composite sans pont thermique, dont les caractéristiques mécaniques et géométriques sont remarquables.Thus, thanks to the method of the invention, a temporary connection is created over the entire length of the profiles to be assembled, which partially closes said space and which is kept until the binder introduced in this space is completely hardened, so that the two profiles remain strictly straight. After which, we remove the temporary connection made by means of the longitudinal wing to then obtain a composite profile without thermal bridge, whose mechanical and geometric characteristics are remarkable.

On remarquera que le document DE-A-2 632 375 décrit un procédé de réalisation d'un profilé constitué par l'association de deux profilés métalliques liés par un liant adhésif durcissable, dans lequel lesdits profilés sont temporairement réunis par deux ailes arrachables, portées par l'un des profilés et encliquetables sur l'autre desdits profilés par un mouvement relatif transversal à ces derniers. Un tel procédé connu nécessite que les deux profilés soient durs et élastiques et ne pourraient être mis en oeuvre avec un profilé de bois, dont la matière constitutive, par nature, est tendre et inélastique.It will be noted that document DE-A-2 632 375 describes a process for producing a profile formed by the association of two metal profiles linked by a curable adhesive binder, in which said profiles are temporarily joined by two tear-away wings, carried by one of the profiles and snap onto the other of said profiles by a relative movement transverse to the latter. Such a known method requires that the two profiles be hard and elastic and could not be used with a wooden profile, the constituent material, by nature, is soft and inelastic.

Avantageusement, on prévoit deux ailes longitudinales et espacées l'une de l'autre, délimitant latéralement l'espace dans lequel est introduit ledit liant adhésif durcissable, chaque aile comportant à son bord libre un second élément de relief longitudinal, susceptible de coopérer avec un tel premier élément. Ainsi, on obtient un meilleur maintien des profilés à assembler et, de plus, l'espace à remplir du liant adhésif durcissable est mieux délimité.Advantageously, two longitudinal wings are provided which are spaced from one another, laterally delimiting the space into which said curable adhesive binder is introduced, each wing having at its free edge a second element of longitudinal relief, capable of cooperating with a such first element. Thus, better retention of the profiles to be assembled is obtained and, moreover, the space to be filled with the curable adhesive binder is better defined.

Un premier et un second éléments de relief qui coopérent peuvent être disposés latéralement par rapport auxdits profilés. Ils peuvent également: être disposés dans l'épais­seur de ceux-ci. Lorsque deux ailes longitudinales sont prévues, il est avantageux qu'un couple d'éléments de relief coopérants soit disposé latéralement et que l'autre soit disposé dans l'épaisseur desdits profilés. Ainsi, il est possible d'assembler les profilés par simple emboîtement transversal, après un rapprochement également transversal.First and second relief elements which cooperate can be arranged laterally with respect to said sections. They can also: be arranged in the thickness of these. When two longitudinal wings are provided, it is advantageous that a pair of cooperating relief elements is arranged laterally and that the other is arranged in the thickness of said sections. Thus, it is possible to assemble the profiles by simple transverse interlocking, after also transverse approximation.

Selon une autre caractéristique, on prévoit des moyens d'ancrage du liant adhésif sur chacun desdits profilés. Dans un mode préféré de réalisation, lesdits moyens d'ancrage dudit profilé en bois peuvent être définis par des saignées longitudinales ménagées dans ledit profilé, et, lesdits moyens d'ancrage dudit profilé en métal peuvent être définis par des nervures longitudinales faisant saillie par rapport audit profilé.According to another characteristic, means are provided for anchoring the adhesive binder to each of said sections. In a preferred embodiment, said means for anchoring said wooden profile can be defined by longitudinal grooves formed in said profile, and, said means for anchoring said metal profile can be defined by longitudinal ribs projecting from profiled audit.

Par ailleurs, l'opération d'usinage de l'aile longitudinale, après durcissement du liant adhésif, peut être effectuée par fraisage. De la sorte, puisque la ou les liaisons temporai­res sont supprimées, on obtient un profilé complexe sans pont thermique.Furthermore, the machining operation of the longitudinal flange, after hardening of the adhesive binder, can be carried out by milling. In this way, since the temporary link or links are eliminated, a complex profile is obtained without thermal bridge.

On peut utiliser comme liant adhésif une résine synthétique polymérisable, notamment dans le cas où la liaison entre les profilés à assembler n'est réalisée que par une aile longitudinale. On introduit alors par gravité la résine par la face ouverte de la cavité, opposée à ladite aile. En revanche, dans le cas où la cavité est déterminée par les faces en regard des profilés et par les deux ailes longitu­dinales, on peut utiliser une matière synthétique expansible introduite par injection, ce qui permet de remplir les moindres interstices de la cavité.A polymerizable synthetic resin can be used as adhesive binder, in particular in the case where the connection between the profiles to be assembled is only carried out by a wing longitudinal. The resin is then introduced by gravity through the open face of the cavity, opposite to said wing. On the other hand, in the case where the cavity is determined by the opposite faces of the profiles and by the two longitudinal wings, it is possible to use an expandable synthetic material introduced by injection, which makes it possible to fill the smallest interstices of the cavity.

Sur ces figures, on a illustré la réalisation selon l'inven­tion d'un profilé composite constitué d'un profilé de bois 1 et d'un profilé de métal 2, par exemple en aluminium, soli­darisés par l'intermédiaire d'un liant adhésif durcissable 3.In these figures, the embodiment according to the invention has been illustrated of a composite section consisting of a wooden section 1 and a metal section 2, for example made of aluminum, joined together by means of an adhesive binder curable 3.

Dans la forme de mise en oeuvre de la figure 1, la face longitudinale 4 du profilé métallique 2, qui est disposée en regard de la face longitudinale 5 du profilé de bois 1, se prolonge par une aile latérale et longitudinale 6 s'étendant sur toute la longueur du profilé 2, perpendiculairement à ladite face 4. L'aile longitudinale 6 se termine par un rebord coudé 7 formant nervure, qui est engagé par emboîte­ment ou coulissement dans une rainure correspondante 8 ménagée dans le profilé en bois 1. On comprend donc que les deux profilés 1 et 2 sont maintenus en position sur toute leur longueur par la liaison nervure 7-rainure 8, en définissant, lorsqu'ils sont ainsi réunis, une cavité 9 délimitée par les faces longitudinales et opposées 4 et 5, respectivement du profilé métallique 2 et du profilé en bois 1, et par l'aile longitudinale 6. On introduit alors dans la cavité 9, le liant adhésif 3, tel que, dans ce mode de réalisation, une résine synthétique polymérisable, de fa on à réunir solidement les deux profilés 1 et 2. Avantageuse­ment, pour améliorer l'accrochage de la résine sur les faces 4 et 5 des profilés, on prévoit sur la face 4 du profilé métallique 2, d'autres nervures longitudinales 10, agencées en saillie et dont la section présente par exemple une forme de L, et, sur la face 5 du profilé en bois 1 des saignées longitudinales 11 inclinées. On pourrait envisager, bien entendu, une disposition inverse des saignées et des nervures. De plus, des happes de scellement 12 peuvent être également agencées à force dans les saignées 11, en faisant saillie hors de celles-ci. Une déformation des nervures longitudinales 10, par crantage par exemple, pourrait également être effectuée.In the embodiment of Figure 1, the longitudinal face 4 of the metal profile 2, which is arranged opposite the longitudinal face 5 of the wooden profile 1, is extended by a lateral and longitudinal wing 6 extending over the entire length of the profile 2, perpendicular to said face 4. The longitudinal flange 6 ends in a bent edge 7 forming a rib, which is engaged by fitting or sliding in a corresponding groove 8 formed in the wooden profile 1. We understand therefore that the two sections 1 and 2 are held in position over their entire length by the rib 7-groove 8 connection, defining, when they are thus joined together, a cavity 9 delimited by the longitudinal and opposite faces 4 and 5, respectively of the metal profile 2 and of the wooden profile 1, and through the longitudinal flange 6. The adhesive binder 3 is then introduced into the cavity 9, such that, in this embodiment, a polymeric synthetic resin isable, so as to securely join the two profiles 1 and 2. Advantageously, to improve the attachment of the resin on the faces 4 and 5 of the profiles, other longitudinal ribs are provided on the face 4 of the metal profile 2 10, arranged projecting and whose section has for example an L shape, and, on the face 5 of the wooden profile 1 of the inclined longitudinal grooves 11. One could of course envisage a reverse arrangement of the grooves and the ribs. In addition, sealing catches 12 can also be force-fitted into the grooves 11, by projecting therefrom. A deformation of the longitudinal ribs 10, for example by notching, could also be carried out.

Ainsi, après le durcissement de la résine 3, les deux profilés 1 et 2 sont fermement solidarisés l'un à l'autre, l'adhérence entre les deux profilés étant maximale.Thus, after the resin 3 has hardened, the two sections 1 and 2 are firmly joined to each other, the adhesion between the two sections being maximum.

Par ailleurs, grâce à la liaison nervure 7-rainure 8, les deux profilés 1 et 2, lors du durcissement de la résine, restent rigoureusement en position, en étant rectilignes et parallèles l'un par rapport à l'autre.Furthermore, thanks to the rib 7-groove 8 connection, the two sections 1 and 2, during the hardening of the resin, remain strictly in position, being rectilinear and parallel with respect to each other.

Puis, après polymérisation de la résine 3, on élimine l'aile longitudinale 6 par une fraise 14 partiellement représentée sur la figure 1, et qui vient supprimer la zone hachurée 15 de l'aile 6. On obtient ainsi, grâce au procédé de l'inven­tion, un profilé composite 16, représenté sur la figure 4, sans pont thermique, ce qui permet d'éviter les phénomènes de condensation et de procurer une bonne isolation thermique. Par ailleurs, les caractéristiques mécaniques, notamment de rigidité et de géométrie, notamment de linéarité, du profilé composite 16 sont respectées.Then, after polymerization of the resin 3, the longitudinal wing 6 is eliminated by a cutter 14 partially shown in FIG. 1, and which removes the hatched zone 15 from the wing 6. This is obtained, thanks to the process of the invention, a composite section 16, shown in Figure 4, without thermal bridge, which avoids the phenomena of condensation and provide good thermal insulation. Furthermore, the mechanical characteristics, in particular of rigidity and geometry, in particular of linearity, of the composite profile 16 are respected.

Dans la variante de mise en oeuvre illustrée sur la figure 2, la face 4 du profilé métallique 2 se prolonge vers le profilé 1 par deux ailes latérales identiques et parallèles 6A et 6B, portées par ses deux bords longitudinaux. Dans chacune de ces ailes est ménagée une rainure longitudinale 6C délimitée par un épaulement longitudinal 6D et par un rebord d'extrémité incliné 6E. Ainsi, dans ces rainures 6C peuvent se loger, par coulissement longitudinal, des nervures correspondantes 17, taillées dans le profilé en bois 1. On réalise, dans cette variante, deux liaisons temporaires sur toute la longueur des profilés accentuant le maintien en position des deux profilés. Par ailleurs, la cavité 9 est alors délimitée par les faces 4 et 5 des profilés respectivement 2 et 1 et par les deux ailes longitudinales 6A et 6B.In the variant implementation illustrated in FIG. 2, the face 4 of the metal profile 2 extends towards the profile 1 by two identical and parallel lateral wings 6A and 6B, carried by its two longitudinal edges. In each of these wings is formed a longitudinal groove 6C delimited by a longitudinal shoulder 6D and by an inclined end flange 6E. Thus, in these grooves 6C can be accommodated, by longitudinal sliding, corresponding ribs 17, cut in the wooden profile 1. In this variant, two temporary connections are made over the entire length of the profiles accentuating the holding in position of the two profiles. Furthermore, the cavity 9 is then delimited by the faces 4 and 5 of the sections 2 and 1 respectively and by the two longitudinal wings 6A and 6B.

Puisque la cavité est fermée, on peut alors utiliser, comme liant adhésif, une matière synthétique expansible 3 qui est injectée dans la cavité. La matière 3, lors de son expan­sion, tend à presser les nervures longitudinales 17 du profilé en bois 1 contre les rebords inclinés 6E du profilé métallique 2, ce qui procure, avec les moyens d'accrochage 10, 11 et 12 analogues à ceux de la figure 1, une immobili­sation totale des profilés 1 et 2 par la matière 3. Là encore, durant l'expansion de la matière synthétique, les deux profilés restent rectilignes par les liaisons précitées. Puis, par l'intermédiaire de la fraise 14, on élimine les zones hachurées 15 des ailes longitudinales 6A et 6B pour obtenir le profilé composite 16 montré sur la figure 4.Since the cavity is closed, an expandable synthetic material 3 can then be used as an adhesive binder which is injected into the cavity. The material 3, during its expansion, tends to press the longitudinal ribs 17 of the wooden profile 1 against the inclined edges 6E of the metal profile 2, which provides, with the fastening means 10, 11 and 12 similar to those of Figure 1, a total immobilization of the profiles 1 and 2 by the material 3. Again, during the expansion of the synthetic material, the two profiles remain rectilinear by the aforementioned connections. Then, by means of the cutter 14, the hatched zones 15 of the longitudinal wings 6A and 6B are eliminated in order to obtain the composite section 16 shown in FIG. 4.

Dans une autre variante de mise en oeuvre, illustrée sur la figure 3, les ailes longitudinales 6A et 6B prolongent la face 5 du profilé en bois 1 et s'étendent sur toute sa longueur, perpendiculairement à la face 5.In another variant of implementation, illustrated in FIG. 3, the longitudinal wings 6A and 6B extend the face 5 of the wooden profile 1 and extend over its entire length, perpendicular to the face 5.

On prévoit alors dans chacune des ailes une rainure longitu­dinale 6F. Ainsi, les bords longitudinaux 4A, formant nervure, de la face 4 dudit profilé 2 s'engagent, par coulissement, dans les rainures 6F des ailes. Par consé­quent, les deux profilés sont maintenus convenablement l'un à l'autre. On injecte alors dans la cavité 9, délimitée par les faces 4 et 5 des profilés et par les ailes longitudina­les 6A et 6B, la matière synthétique 3, après quoi, on procède à l'élimination des ailes 6A et 6B au moyen de la fraise 14.A longitudinal groove 6F is then provided in each of the wings. Thus, the longitudinal edges 4A, forming a rib, of the face 4 of said profile 2 engage, by sliding, in the grooves 6F of the wings. Therefore, the two profiles are properly held together. Then injected into the cavity 9, delimited by the faces 4 and 5 of the profiles and by the longitudinal wings 6A and 6B, the synthetic material 3, after which, we proceed to the elimination of the wings 6A and 6B by means of the cutter 14.

On obtient là encore un profilé composite 16 rigoureusement rectiligne sans pont thermique.Here again, a strictly straight composite profile 16 is obtained without thermal bridge.

Dans les réalisations des figures 2 et 3, les rainures et nervures coopérantes des deux profilés 1 et 2 sont toutes latérales, de sorte que lesdits profilés ne peuvent être assemblés l'un à l'autre que par coulissement longitudinal. En revanche, sur la figure 5, on a représenté un mode de réalisation dans lequel un couple de nervure et rainure coopérantes est latéral, tandis que l'autre couple se trouve dans l'épaisseur desdits profilés. Ainsi, il est possible d'assembler lesdits profilés par rapprochement transversal, puis emboîtement. Comme on peut le voir, le couple coopérant latéral est voisin de celui portant les références 17,6C sur la figure 2.In the embodiments of FIGS. 2 and 3, the cooperating grooves and ribs of the two sections 1 and 2 are all lateral, so that said sections can only be joined to one another by longitudinal sliding. On the other hand, in FIG. 5, an embodiment is shown in which a pair of cooperating rib and groove is lateral, while the other pair is located in the thickness of said sections. Thus, it is possible to assemble said sections by transverse approximation, then interlocking. As can be seen, the lateral cooperating torque is close to that bearing the references 17.6C in FIG. 2.

Dans la réalisation de la figure 5, on a prévu un évidement 30 dans la face 5 du profilé 1 ; cet évidement comporte une paroi latérale formant une saillie 31, en direction de la nervure 17. De plus, une aile 6 comporte un repliement 6G à 90°, prolongé par une aile 6H, telle qu'une rainure 32 soit formée entre les ailes 6G et 6H, rainure dont le profilé correspond à celui de la saillie 31. Ainsi, après avoir été rapprochés l'un de l'autre transversalement, lesdits profilés 1 et 2 peuvent être assemblés par un mouvement relatif de la droite vers la gauche de la figure 5.In the embodiment of Figure 5, there is provided a recess 30 in the face 5 of the profile 1; this recess has a side wall forming a projection 31, in the direction of the rib 17. In addition, a wing 6 has a folding 6G at 90 °, extended by a wing 6H, such that a groove 32 is formed between the wings 6G and 6H, groove the profile of which corresponds to that of the projection 31. Thus, after having been brought together from one another transversely, said profiles 1 and 2 can be assembled by a relative movement from the right to the left of the figure 5.

Une application préférentielle des profilés composites 16, obtenus à partir du procédé de l'invention, au domaine de la menuiserie, est illustrée sur la figure 6. Pour cela, on a représenté partiellement en coupe transversale une fenêtre 20, dont la partie fixe ou dormant 21 et la partie mobile ou ouvrant 22 sont réalisées à partir des profilés composites.A preferred application of the composite sections 16, obtained from the process of the invention, in the field of carpentry, is illustrated in FIG. 6. For this, a window 20 has been shown partially in cross section, the fixed part or frame 21 and the movable or opening part 22 are made from composite profiles.

Le profilé composite 16A de l'ouvrant 22 supporte le vitrage isolant 23 et son profilé en bois 1A est relié par une articulation 24 au profilé en bois 1B du profilé composite 16B constituant le dormant 21 de la fenêtre 20. On notera de plus la parfaite adhérence entre les profilés en bois et en métal de chaque profilé 16A et 16B au moyen du liant isolant 3.The composite profile 16A of the opening 22 supports the insulating glazing 23 and its wooden profile 1A is connected by a hinge 24 to the wooden profile 1B of the composite profile 16B constituting the frame 21 of the window 20. The perfect is also noted adhesion between the wooden and metal profiles of each profile 16A and 16B by means of the insulating binder 3.
