The sections are maintained on the structural elements by fixing studs (7) distributed along the sections, spaced from one another. The studs comprise a polygonal base (71), a narrow central part (72) and a head with pins (73), the head being inserted between two ribs supporting the section by being engaged with the splines (406), and the base being set between these splines and the structural element to ensure a continuous spacing between the plastic section and the structural element. The invention is applicable to building woodwork, such as windows or the like.

Description

Système de protection d'éléments structurels de menuiserie de bâtiment Protection system for structural elements of building joinery
La présente invention concerne un système de protection d'éléments structurels de menuiserie de bâtiment, tels que notamment des châssis de fenêtre ou porte-fenêtre, ou tout autre élément de structure considéré classiquement comme faisant partie du domaine de la menuiserie de bâtiment, par exemple des éléments porteurs d'une véranda, et de manière générale tout élément ayant une forme allongée et profilée et participant à la rigidité de la dite structure. II est encore précisé que par menuiserie on entend en particulier la menuiserie bois mais également la menuiserie métallique, en particulier en alliage d'aluminium, et la menuiserie plastique.The present invention relates to a system for protecting structural elements of building carpentry, such as in particular window frames or French windows, or any other structural element conventionally considered to be part of the field of building carpentry, for example elements carrying a veranda, and generally any element having an elongated and profiled shape and participating in the rigidity of said structure. It is further specified that by carpentry is understood in particular wood carpentry but also metal carpentry, in particular aluminum alloy, and plastic carpentry.
Dans le domaine des menuiseries extérieures pour bâtiment, les châssis (cadres de dormants ou de vantaux) étaient traditionnellement réalisés en bois, ou en métal, jusqu'à ce qu'apparaissent les châssis en matière plastique ou composite, notamment en PVC, chacun de ces matériaux possédant ses avantages et inconvénients spécifiques biens connus.In the field of exterior joinery for buildings, the frames (frames of frames or leaves) were traditionally made of wood, or metal, until the frames appear in plastic or composite material, in particular PVC, each of these materials having its specific advantages and disadvantages well known.
Pour des raisons notamment esthétiques, il est connu de munir les structures métalliques, en alliage léger tel que l'aluminium, ou plastiques, d'un habillage en bois du côté intérieur. Un inconvénient des structures de ce type est que la réalisation des châssis est tributaire des fabricants de profilés, n'autorisant pas toute la souplesse que 1 ' on pourrait souhaiter pour les formes de l'habillage bois. Par ailleurs, d'autres problèmes propres aux réalisations en profilés aluminium ou de type PVC subsistent :For notably aesthetic reasons, it is known to provide metallic structures, in light alloy such as aluminum, or plastics, with a wooden covering on the inner side. A disadvantage of structures of this type is that the production of the frames is dependent on the manufacturers of profiles, not allowing all the flexibility that one could wish for the forms of the wooden covering. In addition, other problems specific to realizations in aluminum profiles or PVC type remain:
- difficulté des assemblages et de la fixation des quincailleries , détériorations, par exemple par rayures ou brûlures, des surfaces exposées de ces profilés, qui ne peuvent être réparées que par un remplacement coûteux de l'élément détérioré, sinon même de l'ensemble du châssis dans les cas où les profilés d'origines ne se trouvent plus disponibles sur le marché, ce qui est assez fréquent au bout de plusieurs années,- difficulty in assembling and fixing the hardware, damage, for example by scratches or burns, of the exposed surfaces of these profiles, which can only be repaired by an expensive replacement of the damaged element, or even of the entire chassis in cases where the original profiles are no longer available on the market , which is quite common after several years,
- usure ou marquage dans les zones soumises à des mouvements ou à des efforts lors des ouvertures et fermetures des vantaux, etc. On connaît aussi des châssis à structure en bois recevant un recouvrement en profilé aluminium avec de nombreuses variantes de fixation de ces profilés sur le bois. Mais ces revêtements sont classiquement fixés et solidaires du bois par des éléments qui pénètrent dans le bois et qui, par soucis d'esthétique, ne sont pas visibles ni accessibles une fois assemblés. Les profilés de recouvrement sont donc pratiquement indémontables sauf à détériorer le châssis en bois, ce qui rend pratiquement impossible toute réparation locale. De plus, de tels assemblages sont soumis à des problèmes de dilatations différentielles entre le revêtement aluminium et le bois, et à des problèmes de condensation et de conduite des eaux de ruissellement (drainage et ventilation de l'interface bois-aluminium), qui peuvent rapidement détériorer le bois soumis à une humidité persistante sous le revêtement. Egalement, la mise en oeuvre de tels revêtements nécessite des machines spéciales et demande des moyens complexes de protection, rendant la fabrication de tels châssis compliquée et coûteuse. Les problèmes de détériorations de surface irréparables, déjà évoqués ci-dessus pour les profilés métalliques, subsistent également dans ce type de réalisation.- wear or marking in areas subject to movement or stress when opening and closing the leaves, etc. Chassis with a wooden structure are also known which receive an aluminum profile covering with numerous variants for fixing these profiles to wood. But these coatings are conventionally fixed and secured to the wood by elements which penetrate into the wood and which, for aesthetic reasons, are not visible or accessible once assembled. The cover profiles are therefore practically removable without damaging the wooden frame, which makes local repair practically impossible. In addition, such assemblies are subject to problems of differential expansion between the aluminum coating and the wood, and to problems of condensation and conduct of runoff water (drainage and ventilation of the wood-aluminum interface), which can rapidly deteriorate wood subject to persistent moisture under the coating. Also, the implementation of such coatings requires special machines and requires complex means of protection, making the manufacture of such chassis complicated and expensive. The problems of irreparable surface deterioration, already mentioned above for metal profiles, also persist in this type of embodiment.
De manière générale, on peut dire que les problèmes rencontrés dans des structures des types évoqués ci- dessus, ainsi que dans des structures similaires formant une interface, généralement mais non exclusivement vitrée et ouvrante, entre l'intérieur et l'extérieur d'un bâtiment, sont de deux ordres :In general, it can be said that the problems encountered in structures of the types mentioned above, as well as in similar structures forming an interface, generally but not exclusively glazed and opening, between the interior and exterior of a building, are of two types:
- d'une part, les problèmes liés au comportement différent des matériaux associés, par exemple bois et aluminium, lorsque le revêtement situé vers l'extérieur est soumis aux conditions climatiques et intempéries alors que la structure porteuse est soumises aux conditions ambiantes de l'intérieur du bâtiment, d'autre part, les problèmes dûs à la liaison entre les éléments de structure et le revêtement, cette liaison pouvant empêcher les déformations différentielles entre éléments porteurs et revêtement, et pouvant également empêcher une aération de 1 ' interface entre ceux-ci, ce qui peut à terme entraîner une détérioration du matériau des éléments porteurs, en particulier lorsqu'ils sont en bois.- on the one hand, the problems linked to the different behavior of the associated materials, for example wood and aluminum, when the coating situated towards the outside is subjected to climatic and weather conditions while the supporting structure is subjected to the ambient conditions of the interior of the building, on the other hand, the problems due to the connection between the structural elements and the coating, this connection being able to prevent differential deformations between load-bearing elements and coating, and also being able to prevent aeration of the interface between them ci, which can eventually lead to deterioration of the material of the load-bearing elements, especially when they are made of wood.
La présente invention a pour but de résoudre ces problèmes et vise particulièrement à fournir un système de protection extérieure de menuiseries de bâtiment qui : - assure une protection efficace en soustrayant les éléments de structure à l'agression directe des conditions climatiques extérieures, tout en préservant une indépendance du comportement des éléments de structure et du revêtement lors des variations des conditions climatiques ou ambiantes,The present invention aims to solve these problems and aims in particular to provide an exterior protection system for building joinery which: - provides effective protection by removing structural elements from direct attack from external climatic conditions, while preserving independence of the behavior of the structural elements and of the covering during variations in climatic or ambient conditions,
- supprime au maximum les ponts thermiques entre éléments de structure et revêtement, et évite les phénomène dûs à une hygrométrie mal contrôlée au niveau de leur interface, - permette une adaptation aisée du revêtement sur des menuiseries existantes,- eliminates as much as possible the thermal bridges between structural elements and covering, and avoids the phenomena due to a poorly controlled humidity at their interface, - allows an easy adaptation of the covering on existing joinery,
- permette un remplacement facile du revêtement ou d'une partie seulement de celui-ci, sans risque de détériorer les éléments de structure, - assure un aspect esthétique, en accord avec l'environnement de la menuiserie, lequel présente classiquement un aspect différent entre l'extérieur et 1 ' intérieur, l'ensemble de ces fonctions contribuant à la fiabilité et à la durabilité des menuiseries ainsi protégées .- allows easy replacement of the covering or only part of it, without risk of damaging the structural elements, - ensures an aesthetic appearance, in accordance with the environment of the carpentry, which has conventionally a different aspect between the exterior and the interior, all of these functions contributing to the reliability and durability of the joinery thus protected.
Avec ces objectifs en vue, l'invention a pour objet un système de protection d'éléments structurels de menuiserie de bâtiment, caractérisé en ce qu'il comporte des éléments de recouvrement constitués de profilés en matière plastique de type PVC recouvrant par l'extérieur les éléments de la structure, les dits profilés comportant une paroi frontale et au moins deux nervures s ' étendant sensiblement perpendiculairement à partir de la paroi frontale et définissant entre elles une rainure de guidage, les dites nervures étant pourvues sur leurs bords opposés à la paroi frontale de premières languettes s ' étendant l'une vers l'autre, les profilés étant maintenus sur les dits éléments de structure par des plots de fixation répartis sur la longueur des profilés, espacés l'un de l'autre, les dits plots comportant une embase polygonale, une partie centrale rétrécie et une tête à ergots, la tête s ' insérant entre deux nervures et maintenant le profilé par engagement des ergots avec les dites premières languettes, et l'embase étant interposée entre les premières languettes et l'élément de structure pour assurer un espacement continu entre le profilé plastique et l'élément de structure.With these objectives in view, the invention relates to a system for protecting structural elements of building carpentry, characterized in that it comprises covering elements made up of plastic profiles of PVC type covering on the outside. the elements of the structure, the said profiles comprising a front wall and at least two ribs extending substantially perpendicularly from the front wall and defining between them a guide groove, the said ribs being provided on their edges opposite to the wall front of first tongues extending towards each other, the profiles being held on said structural elements by fixing studs distributed over the length of the profiles, spaced from one another, said studs comprising a polygonal base, a narrowed central part and a lug head, the head being inserted between two ribs and maintaining the profile by e ngagement of the lugs with said first tabs, and the base being interposed between the first tabs and the structural element to ensure continuous spacing between the plastic profile and the structural element.
Comme on le comprendra mieux par la suite, le système selon l'invention permet d'atteindre tous les buts visés indiqués précédemment :As will be better understood hereinafter, the system according to the invention makes it possible to achieve all the aims mentioned above:
- l'utilisation de profilés de recouvrement en matière plastique, préférentiellement en PVC, assure une protection efficace et durable des éléments de structure, que ceux ci soient en bois, en métal (acier ou aluminium), ou même en matière plastique. Dans le cas d'une structure en bois en particulier, le recouvrement extérieur total de celui-ci par le profilé en matière plastique assure une parfaite protection du bois en le soustrayant totalement aux agressions climatiques directes (pluie, rayonnement solaire, etc) . - l'espacement garanti entre le profilé et la structure, assuré par les embases des plots de fixation, ainsi que le fait que ces plots laissent entre eux de larges espacements ouverts, permet d'assurer une parfaite ventilation de 1 ' interface entre la structure et le revêtement, y évitant toute accumulation durable d'humidité et évitant donc tout effet nocif à long terme d'une telle humidité sur la structure (pourrissement du bois, rouille dans le cas de structures métalliques en acier) . - les caractéristiques isolantes du matériau du profilé évitent en grande partie les problèmes de condensation sur la face intérieure du profilé de recouvrement qui existent classiquement pour des profilés de recouvrement en aluminium, cet avantage se combinant de manière particulièrement avantageuse avec la ventilation prémentionnée.- The use of plastic cover profiles, preferably PVC, provides effective and lasting protection of structural elements, whether these are made of wood, metal (steel or aluminum), or even plastic. In the case of a particular wooden structure, the covering total exterior of it by the plastic profile ensures perfect protection of the wood by completely removing it from direct climatic aggressions (rain, solar radiation, etc.). - the guaranteed spacing between the profile and the structure, ensured by the bases of the fixing studs, as well as the fact that these studs leave wide open spaces between them, ensures perfect ventilation of the interface between the structure and the coating, avoiding any lasting accumulation of humidity and thus avoiding any harmful long-term effect of such humidity on the structure (rotting of the wood, rust in the case of metallic steel structures). - The insulating characteristics of the profile material largely avoid the problems of condensation on the inside of the cover profile which conventionally exist for aluminum cover profiles, this advantage being combined in a particularly advantageous manner with the aforementioned ventilation.
- l'utilisation de plots de fixation, préférentiellement en matière plastique, limite au maximum tout effet de pont thermique entre le profilé de recouvrement et la structure, au contraire de tous les systèmes connus dans lesquels, même lorsque le profilé lui-même n'est pas en contact direct avec la structure, la liaison entre profilé de recouvrement et structure est assurée par des éléments de type à feuillure s 'étendant longitudinalement sur de longues distances, qui d'ailleurs empêche également une bonne ventilation de l'interface profilé-structure.- The use of fixing pads, preferably made of plastic, limits to the maximum any thermal bridge effect between the covering profile and the structure, unlike all known systems in which, even when the profile itself does not is not in direct contact with the structure, the connection between cover profile and structure is ensured by rebate type elements extending longitudinally over long distances, which moreover also prevents good ventilation of the profile interface. structure.
- le maintien du profilé sur la structure par les dits plots n'empêche pas un coulissement relatif du profilé sur les plots, autorisant donc une libre déformation de dilatation longitudinale des profilés par rapport à la structure.- the maintenance of the profile on the structure by the said studs does not prevent a relative sliding of the profile on the studs, thus allowing a free deformation of longitudinal expansion of the profiles by relation to the structure.
- les plots conforme à l'invention permettent, comme on le verra mieux par la suite, un montage aisé des profilés sur la structure, même sur des structures à rénover en place, et autorisent de même une dépose ultérieure du profilé sans détérioration de la structure.- the studs according to the invention allow, as will be seen more clearly below, easy mounting of the profiles on the structure, even on structures to be renovated in place, and also allow a subsequent removal of the profile without deterioration of the structure.
Un autre avantage du profilé de recouvrement en plastique réside dans la qualité d'isolation phonique qu'il procure. Un autre avantage encore du système selon l'invention dans le cas de l'utilisation du profilé plastique sur une structure bois, est qu'il permet de conserver l'aspect esthétique du bois du côté intérieur et tous les avantages des structures classiques en bois, notamment la possibilité d'intervenir en réparation ou en remplacement d'un élément quelconque de la structure bois, sans être tributaire, comme cela est le cas dans les structures métalliques ou PVC recevant un recouvrement intérieur en bois, d'une forme spécifique des éléments de structure en de tels matériaux.Another advantage of the plastic cover profile is the quality of sound insulation it provides. Yet another advantage of the system according to the invention in the case of the use of the plastic profile on a wooden structure, is that it allows the aesthetic appearance of the wood to be preserved on the interior side and all the advantages of conventional wooden structures. , in particular the possibility of intervening in repair or replacement of any element of the wooden structure, without being dependent, as is the case in metallic or PVC structures receiving an interior wooden covering, of a specific form of structural elements of such materials.
On notera aussi un avantage particulier du point de vue économique dans le cas de menuiseries neuves en bois : du fait de 1 ' étanchéité apportée par le profilé, on supprime le risque de pénétration d'humidité au niveau des assemblages bois sur bois dans les angles. En conséquence, il devient possible de simplifier fortement ces assemblages en remplaçant les assemblages à mortaises compliquées utilisés classiquement par de simples assemblages en onglet par exemple. Selon une disposition particulière de l'invention, le profilé peut être teinté dans la masse ou, préférentiellement , au moyen d'une couche de peinture ou matière plastique teintée déposée sur la surface visible et entrant en liaison chimique avec le plastique du profilé, donnant ainsi en plus d'un fini particulièrement esthétique, une grande résistance au rayonnement ultra- violet et à l'abrasion, sans risque d'ecaillage en cas de choc .We will also note a particular advantage from the economic point of view in the case of new wooden joinery: due to the tightness provided by the profile, the risk of moisture penetration at the level of the wood on wood assemblies in the corners is eliminated. . Consequently, it becomes possible to greatly simplify these assemblies by replacing the complicated mortise assemblies conventionally used by simple miter assemblies for example. According to a particular arrangement of the invention, the profile can be dyed in the mass or, preferably, by means of a layer of paint or tinted plastic material deposited on the visible surface and entering into chemical bond with the plastic of the profile, giving so in addition to a particularly aesthetic finish, great resistance to ultra- purple and abrasion, without risk of chipping in the event of impact.
Selon une autre disposition, les profilés sont assemblés pour former un cadre, l'assemblage d'angle entre deux profilés étant réalisé en onglet, et les deux dits profilés étant liés ensemble avec leurs parois frontales dans un même plan, au moyen de pièces d'assemblages insérées entre la face arrière de la paroi frontale et des secondes languettes qui s ' étendent à partir des nervures ou des ailes.According to another arrangement, the profiles are assembled to form a frame, the corner assembly between two profiles being produced in a miter, and the two said profiles being linked together with their front walls in the same plane, by means of parts d 'assemblies inserted between the rear face of the front wall and second tabs which extend from the ribs or wings.
D'autres caractéristiques et avantages apparaîtront dans la description qui va être faite à titre d'exemple d'une fenêtre conforme à l'invention.Other characteristics and advantages will appear in the description which will be given by way of example of a window according to the invention.

La fenêtre représentée est constituée d'un cadre dormant 1 en bois comportant une traverse supérieure 101, une traverse inférieure 102, et deux montants latéraux 103, et de deux vantaux 2 et 3 comportant également chacun une traverse supérieure 201, une traverse inférieure 202, un montant latéral 203 et un montant central 204. Tous ces éléments structurels sont profilés et assemblés de manière connue en soi, et comportent des joints de type courant pour assurer 1 ' étanchéité à l'air entre les vantaux et le dormant.The window shown consists of a wooden frame 1 comprising an upper cross member 101, a lower cross member 102, and two lateral uprights 103, and two leaves 2 and 3 each also comprising an upper cross member 201, a lower cross member 202, a lateral upright 203 and a central upright 204. All these structural elements are profiled and assembled in a manner known per se, and include seals of the standard type to ensure air tightness between the leaves and the frame.
Chaque élément est recouvert du côté extérieur par un profilé en PVC. Trois types de profilés sont utilisés, mais présentent tous des similitudes de profils comme on le voit aisément sur les divers dessins. Un premier profil 4 est utilisé pour le recouvrement des éléments de structure 101, 102, 103 du dormant ; un deuxième profil 5 est utilisé pour le recouvrement des éléments de structure 201, 202 ,203, 204 des vantaux ; et un troisième profil 6 est prévu pour le recouvrement de la jonction entre les deux vantaux (voir figure 2) . Le premier profil 4 comporte :Each element is covered on the outside with a PVC profile. Three types of profiles are used, but all have similarities in profiles as can easily be seen in the various drawings. A first profile 4 is used for covering the structural elements 101, 102, 103 of the frame; a second profile 5 is used for covering the structural elements 201, 202, 203, 204 of the leaves; and a third profile 6 is provided for covering the junction between the two leaves (see FIG. 2). The first profile 4 comprises:
- une paroi frontale 401,- a front wall 401,
- trois nervures 402, 403, 404 s ' étendant parallèlement entre elles à partir de la paroi frontale et sensiblement perpendiculairement à celle-ci, - une aile 405 qui s'étend obliquement à partir d'un bord de la paroi frontale,- three ribs 402, 403, 404 extending parallel to each other from the front wall and substantially perpendicular thereto, a wing 405 which extends obliquely from an edge of the front wall,
- des premières languettes 406 qui s'étendent l'une vers l'autre à partir des bords de nervures, - un premier sabot 407 qui s'étend sensiblement parallèlement à la paroi frontale à partir du bord de la nervure 42 la plus éloignée de l'aile,- first tongues 406 which extend towards one another from the edges of ribs, - a first shoe 407 which extends substantially parallel to the front wall from the edge of rib 42 furthest from the wing,
- un deuxième sabot 408 qui s'étend vers l'aile 405 à partir du bord de la nervure 402 la plus proche de l'aile,a second shoe 408 which extends towards the wing 405 from the edge of the rib 402 closest to the wing,
- des secondes languettes 91 s ' étendant à partir de chaque nervure, à proximité de la paroi frontale.- Second tabs 91 extending from each rib, near the front wall.
Le bord de l'aile 405 présente deux lèvres 410 disposées en triangle ménageant entr' elles une rainure longitudinale 411.The edge of the wing 405 has two lips 410 arranged in a triangle forming between them a longitudinal groove 411.
Les languettes 406, les sabots 407, 408, et les lèvres 410 de l'aile 405 sont situés sensiblement dans un même plan parallèle à la paroi frontale et formant la face arrière du profilé. Le deuxième profil 5 est similaire, se distinguant du premier seulement par le fait qu'il est moins large, ne comporte que deux nervures 502, 503, et que le premier sabot 507 est plus court et a une forme identique au deuxième sabot 508. Le troisième profil 6 est similaire au deuxième, mais comporte deux ailes 605 symétriques.The tongues 406, the shoes 407, 408, and the lips 410 of the wing 405 are situated substantially in the same plane parallel to the front wall and forming the rear face of the profile. The second profile 5 is similar, differing from the first only in that it is narrower, has only two ribs 502, 503, and that the first shoe 507 is shorter and has a shape identical to the second shoe 508. The third profile 6 is similar to the second, but has two symmetrical wings 605.
Les plots de fixation 7, préférentiellement en polyamide, comportent, axialement superposés, une embase polygonale 71, une partie centrale rétrëcie 72 et une tête 73. La dimension de l'embase est supérieure à la distance entre les languettes 406 du profilé, alors que le diamètre de la partie centrale 72 est inférieur à cette distance. La tête 73 à une forme rectangulaire ou oblongue, ayant une largeur inférieure à la distance entre les dites languettes, et une longueur supérieure à celle-ci mais inférieure à l'écartement entre deux nervures adjacentes, formant ainsi deux ergots 731 diamétralement opposés. La hauteur axiale de la partie centrale 72 est sensiblement égale à l'épaisseur des languettes 406. Chaque plot est fixé sur la structure bois par une vis, par exemple de diamètre 3,5 mm, passant dans un perçage axial 74 du plot, sans être fortement serrée, de manière à permettre une rotation du plot autour de la vis. Avant la mise en place du profilé, les plots sont orientés de manière que les ergots 731 de leurs têtes soient orientés selon la direction longitudinale du profilé. Ainsi le profilé peut être mis en position, les têtes 73 des plots s ' engageant sans contrainte entre les languettes des nervures, jusqu'à ce que les dites languettes viennent en appui sur les embases. Dans cette position, un écartement constant, déterminé par l'épaisseur de l'embase, (environ 3 mm par exemple) existe en tout point entre le profilé plastique et l'élément de structure, c'est à dire que nulle part le profilé n'est en contact avec le bois de la structure. On peut alors, au moyen d'une clé plate glissée dans cet espacement par le côté du profilé et engagée sur la forme polygonale de l'embase, faire tourner le plot de manière que les ergots viennent se placer sur les languettes, assurant ainsi le maintien du profilé. On notera que ce mode de fixation laisse au profilé la possibilité de coulisser longitudinalement , comme cela à déjà été indiqué, en cas de dilatation longitudinale. Une fois la fixation ainsi réalisée, différents joints peuvent être placés entre les sabots du profilé et le châssis, comme on le verra par la suite.The fixing pads 7, preferably made of polyamide, comprise, axially superimposed, a polygonal base 71, a narrowed central part 72 and a head 73. The dimension of the base is greater than the distance between the tongues 406 of the profile, while the diameter of the central part 72 is less than this distance. The head 73 has a rectangular or oblong shape, having a width less than the distance between said tabs, and a length greater than this but less than the spacing between two adjacent ribs, thus forming two diametrically opposed pins 731. The axial height of the central part 72 is substantially equal to the thickness of the tongues 406. Each stud is fixed to the wooden structure by a screw, for example of 3.5 mm diameter, passing through an axial bore 74 of the stud, without be strongly tightened, so as to allow rotation of the stud around the screw. Before the profile is put in place, the studs are oriented so that the lugs 731 of their heads are oriented in the longitudinal direction of the profile. Thus the profile can be placed in position, the heads 73 of the studs engaging without constraint between the tongues of the ribs, until the said tongues come to bear on the bases. In this position, a constant spacing, determined by the thickness of the base, (approximately 3 mm for example) exists at all points between the plastic profile and the structural element, that is to say that nowhere does the profile is not in contact with the wood of the structure. It is then possible, by means of a flat key slid in this spacing by the side of the profile and engaged on the polygonal shape of the base, to rotate the stud so that the pins are placed on the tongues, thus ensuring the maintaining the profile. It will be noted that this method of fixing leaves the profile with the possibility of sliding longitudinally, as has already been indicated, in the event of longitudinal expansion. Once the fixing has been achieved, different joints can be placed between the profile shoes and the chassis, as we will see later.
On va maintenant décrire, en relation avec les figures 1 à 4, une fenêtre conçue particulièrement en vue de l'utilisation du profilé conforme à l'invention.We will now describe, in relation to Figures 1 to 4, a window designed particularly for the use of the profile according to the invention.
On notera que dans ce cas, la vitre 8 à double vitrage est montée sur le cadre bois du dormant et y est maintenue par les profilés de recouvrement 5. Une cale d'espacement 801 est placée entre le chant de la vitre et le cadre formé par les traverses 201, 202 et les montants 203, 204. Le bord de la vitre s'appuie, via un joint 802, contre une baguette 210 en bois fixé sur le cadre de manière connue en soi ou réalisée d'une pièce avec les éléments du cadre par profilage. Du côté extérieur, le profilé 5 est fixé comme indiqué précédemment, et un joint d'appui et d'étanchéité 803 inséré dans la rainure formée par les lèvres 510 de l'aile 505 du profilé, s'applique contre la face extérieure de la vitre pour la maintenir. Dans le cas de grandes surfaces vitrées et/ou de vitres épaisses, pour renforcer le maintien de la vitre, il est préférentiellement prévu une baguette de renfort 804 insérée entre le chant de la vitre et la cale 801, et fixée sur le cadre avant mise en place de la vitre, par exemple par des vis (représentées uniquement par leur axe 805) . Un repli d'équerre 806 de cette baguette 804 s'engage sur le sabot 508 du profilé 5 pour conforter la fixation assurée par les plots 7 et garantir un parfait maintien de la vitre.Note that in this case, the double-glazed window 8 is mounted on the wooden frame of the frame and is held there by the cover profiles 5. A wedge 801 is placed between the edge of the glass and the frame formed by the crosspieces 201, 202 and the uprights 203, 204. The edge of the glass is supported, via a joint 802, against a strip 210 of fixed wood on the frame in a manner known per se or produced in one piece with the elements of the frame by profiling. On the outside, the section 5 is fixed as indicated above, and a support and sealing joint 803 inserted in the groove formed by the lips 510 of the wing 505 of the section, is applied against the outside face of the glass to maintain it. In the case of large glazed areas and / or thick panes, to reinforce the maintenance of the pane, there is preferably provided a reinforcement strip 804 inserted between the edge of the pane and the wedge 801, and fixed on the frame before placing in place of the glass, for example by screws (represented only by their axis 805). A square fold 806 of this rod 804 engages on the shoe 508 of the profile 5 to reinforce the fixing provided by the studs 7 and guarantee perfect maintenance of the window.
Des orifices 511 sont percés dans les nervures 502, 503, au moins pour les profilés de bas de vantail, pour permettre le drainage des éventuelles condensations. Un joint élastomère 512 est inséré entre le sabot 507 et le cadre pour les montants du vantail (voir figures 2 et 3) , afin de dissimuler à la vue les plots 7 lorsque les vantaux sont ouverts, et sert également à guider de bas en haut la lame d'air circulant entre le profilé et le châssis. On notera qu'il n'y a pas de tel joint utilisé pour les traverses de vantail, afin de ne pas perturber cette circulation d'air.Holes 511 are drilled in the ribs 502, 503, at least for the bottom leaf profiles, to allow drainage of any condensation. An elastomeric seal 512 is inserted between shoe 507 and the frame for the leaf uprights (see FIGS. 2 and 3), in order to conceal from view the studs 7 when the leaves are open, and also serves to guide from the bottom up. the air gap circulating between the profile and the frame. It will be noted that there is no such seal used for the leaf crosspieces, so as not to disturb this air circulation.
On notera que ce type de montage permet un remplacement facile de la vitre en cas de bris, puisqu'il suffit pour cela de déposer les profilés 5. Les profilés 4 recouvrant le dormant sont fixés de manière que leur aile 405 vienne couvrir le bord de la paroi 501 des profilés 5 des vantaux lorsque la fenêtre est fermée, en ménageant un jeu minimal entre le bord de l'aile 405 du profilé 4 du dormant et la surface de la paroi frontale du profilé 5 des vantaux. Un joint à trois lèvres 415 est placé sur le dormant :It will be noted that this type of mounting allows easy replacement of the glass in the event of breakage, since it suffices for this to deposit the sections 5. The sections 4 covering the frame are fixed so that their wing 405 comes to cover the edge of the wall 501 of the profiles 5 of the leaves when the window is closed, leaving minimal clearance between the edge of the wing 405 of the profile 4 of the frame and the surface of the front wall of the profile 5 of the leaves. A joint with three lips 415 is placed on the frame:
- une lèvre 416 est insérée dans une rainure du dormant et assure le maintien du joint.- A lip 416 is inserted into a groove of the frame and maintains the seal.
- une deuxième lèvre 417 vient se prendre sur le sabot 408 du profilé. Elle dissimule à la vue les plots 7 lorsque la fenêtre est ouverte et participe au guidage de la lame d'air circulant entre le profilé et le bois.- A second lip 417 is caught on the shoe 408 of the profile. It conceals from view the studs 7 when the window is open and participates in guiding the air gap circulating between the profile and the wood.
- et la troisième lèvre 418 s'appuie sur le bord du cadre du vantail lorsque la fenêtre est fermée, assurant ainsi une étanchéité à l'air supplémentaire entre vantail et dormant lorsque la fenêtre est fermée.- And the third lip 418 rests on the edge of the leaf frame when the window is closed, thus ensuring an additional air tightness between the leaf and the frame when the window is closed.
Ainsi qu'on le voit figure 3, dans le cas d'un montage de la fenêtre en applique sur feuillure, un joint en mousse compressible 45 peut être placé entre le profilé de recouvrement 4 et la paroi du mur, la finition pouvant être assurée par un joint en mastic silicone 46.As seen in Figure 3, in the case of mounting the window on the rebate, a compressible foam seal 45 can be placed between the cover profile 4 and the wall of the wall, the finish can be provided by a silicone sealant seal 46.
Comme les profilés 4 comportent trois nervures, des plots de fixation 7 peuvent être placés entre les nervures 402 et 403 et aussi entre les nervures 403 et 404. L'accès à l'embase des plots est possible par le bord intérieur du dormant avant que le joint à trois lèvres 415 soit mis en place ( ou après retrait de ce joint en cas de démontage) .As the profiles 4 have three ribs, fixing studs 7 can be placed between the ribs 402 and 403 and also between the ribs 403 and 404. Access to the base of the studs is possible by the inner edge of the frame before the three-lip seal 415 is in place (or after removal of this seal in the event of disassembly).
Des orifices 411 sont percés dans les profilés horizontaux en haut et en bas du dormant, pour permettre la circulation d'air et l'évacuation des condensations ou infiltrations d'eau éventuelles.Holes 411 are drilled in the horizontal profiles at the top and bottom of the frame, to allow the circulation of air and the evacuation of any condensation or water infiltration.
Lors du montage, des équerres plates 9, en polyamide par exemple, sont insérées, dans les angles formés par les profilés horizontaux et verticaux (voir figure 4) , tant pour les profilés 5 de recouvrement des vantaux que pour les profilés 4 de recouvrement du dormant, entre la paroi frontale 401, 501 des profilés et les languettes complémentaires 91 formées sur les nervures. Ces équerres assurent une bonne liaison des profilés dans les angles et garantissent une planéité continue entre profilés. Ces équerres peuvent être crantées pour assurer un auto-blocage après avoir été insérées à force dans les profilés, la liaison pouvant être complétée par une colle, par exemple de type cyano- acrylate . Le profilé 6 est fixé, de la même manière qu'indiqué précédemment, sur le montant central d'un des vantaux, une de ses ailes 605 couvrant le profilé 5 de ce vantail, comme on le voit figure 2, et l'autre aile 605' venant couvrir le profilé 5 fixé sur le montant central de l'autre vantail lorsque la fenêtre est fermée.During assembly, flat brackets 9, made of polyamide for example, are inserted, in the angles formed by the horizontal and vertical profiles (see FIG. 4), both for the profiles 5 for covering the leaves and for the profiles 4 for covering the standing between the front wall 401, 501 of the profiles and the complementary tongues 91 formed on the ribs. These brackets ensure a good connection of the profiles in the corners and guarantee a continuous flatness between profiles. These brackets can be notched to ensure self-locking after having been forcibly inserted into the profiles, the connection being able to be completed with an adhesive, for example of cyanoacrylate type. The profile 6 is fixed, in the same manner as indicated above, on the central upright of one of the leaves, one of its wings 605 covering the profile 5 of this leaf, as seen in FIG. 2, and the other wing 605 'coming to cover the section 5 fixed on the central upright of the other leaf when the window is closed.
La variante de réalisation du vantail représentée figure 6 ne diffère du mode de réalisation précédemment décrit que par le remplacement de la cale 801 et de la7 baguette 806 par une seule pièce formée d'un profilé particulier 810, par exemple en matière plastique.The variant embodiment of the leaf shown in FIG. 6 differs from the embodiment previously described only by replacing the wedge 801 and the rod 806 with a single piece formed from a particular profile 810, for example made of plastic.
La figure 7 illustre l'utilisation du système selon l'invention pour la rénovation de fenêtres existantes. Dans un tel cas, la vitre 8 étant maintenue de manière classique sur le châssis bois contre un epaulement extérieur 220, le profilé de recouvrement 5 n'a pas de fonction de maintien de la dite vitre. Le joint d'appui 803 mentionné précédemment est alors remplacé par un profilé 813 qui sert uniquement à recouvrir 1 ' epaulement 220 et assurer 1 ' étanchéité en étant posé en contact avec la vitre, l' étanchéité entre ce profilé et la vitre pouvant être complétée par un joint de mastic silicone.FIG. 7 illustrates the use of the system according to the invention for the renovation of existing windows. In such a case, the window 8 being held in a conventional manner on the wooden frame against an external shoulder 220, the covering profile 5 has no function of maintaining said window. The support joint 803 mentioned above is then replaced by a profile 813 which only serves to cover the shoulder 220 and ensure the seal by being placed in contact with the glass, the seal between this profile and the glass can be completed. by a silicone sealant joint.
La figure 8 illustre l'utilisation du système selon l'invention pour un vantail de remplacement, adapté en lieu et place du vantail d'origine sur le cadre dormant en PVC profilé 104. Le vantail est tout à fait similaire à celui représenté sur les figures 1, 2 et 3. On notera que dans un tel cas, le profilé selon l'invention n'est pas utilisé pour le cadre dormant, et c'est donc le profilé d'origine qui est réutilisé, sans modifications, évitant ainsi les importants travaux qui auraient été requis s'il avait fallu remplacer l'ensemble de la fenêtre. Tout au plus, il pourra être nécessaire d'adapter les joints 105 entre dormant et ouvrant. Une telle possibilité de rénovation de menuiseries plastiques est particulièrement intéressante, puisque c'est classiquement les parties mobiles de la fenêtre qui sont détériorées alors que le dormant est encore en bon état .FIG. 8 illustrates the use of the system according to the invention for a replacement leaf, adapted in place of the original leaf on the frame in profiled PVC 104. The leaf is quite similar to that shown on the Figures 1, 2 and 3. Note that in such a case, the profile according to the invention is not used for the sleeping frame, and it is therefore the original profile which is reused, without modifications, thus avoiding the important work which would have been required the entire window had to be replaced. At most, it may be necessary to adapt the joints 105 between the frame and the opening. Such a possibility of renovating plastic joinery is particularly interesting, since it is conventionally the moving parts of the window which are deteriorated while the frame is still in good condition.
La figure 10 illustre la rénovation d'une ancienne fenêtre bois munie d'un simple vitrage, montrée figure 9. On notera dans ce cas l'utilisation particulière du profilé fixé sur le vantail, où, pour ne pas réduire la surface vitrée, on n'utilise que le bord du profilé, les plots de fixation étant alors placés entre l'aile 505 et la nervure 502 au lieu d'être placés entre les deux nervures comme dans les exemples précédents . On notera aussi que dans cet exemple, la mise en place du joint 415 a nécessité la réalisation d'une rainure 106 dans le châssis bois d'origine. Pour simplifier la rénovation, on pourra avantageusement remplacer la réalisation de cette rainure par la mise en place d'un profilé adapté 107 rapporté et fixé simplement, par exemple par agrafage, comme représenté figure 11. La figure 11 représente une autre variante de rénovation de fenêtre d'un type légèrement différent de celle représentée figures 9 et 10. Ces différents exemples illustrent la grande souplesse d'adaptation du système selon l'invention pour la rénovation de très nombreux types de fenêtres anciennes. On notera aussi que dans ces exemples, le simple vitrage d'origine est remplacé par un double vitrage isolant dont la mise en place et le maintien sont assurés efficacement et très simplement grâce au système de profilés et de plots conformes à l'invention. Un avantage important de l'invention réside dans le fait qu'il suffit de deux profilés de base pour réaliser tous les différents profilés de recouvrement qui ont été montrés précédemment. Les figures 13 et 14 représentent les formes des sections droites de ces deux profilés.FIG. 10 illustrates the renovation of an old wooden window fitted with simple glazing, shown in FIG. 9. In this case, note the particular use of the profile fixed on the leaf, where, in order not to reduce the glazed surface, we only uses the edge of the profile, the fixing studs then being placed between the wing 505 and the rib 502 instead of being placed between the two ribs as in the previous examples. It will also be noted that in this example, the installation of the seal 415 required the production of a groove 106 in the original wooden frame. To simplify the renovation, it is advantageous to replace the production of this groove by the installation of a suitable profile 107 attached and simply fixed, for example by stapling, as shown in Figure 11. Figure 11 shows another variant of renovation of window of a slightly different type from that shown in FIGS. 9 and 10. These different examples illustrate the great flexibility of adaptation of the system according to the invention for the renovation of very many types of old windows. It will also be noted that in these examples, the original single glazing is replaced by an insulating double glazing, the installation and maintenance of which are ensured efficiently and very simply by means of the system of sections and studs in accordance with the invention. An important advantage of the invention resides in the fact that it suffices for two base sections to produce all the different cover sections which have been shown previously. Figures 13 and 14 show the shapes of the cross sections of these two sections.
Le profilé de la figure 13 comporte notamment :The profile of FIG. 13 comprises in particular:
- une paroi frontale 601,- a front wall 601,
- deux nervures 602, 603 s' étendant à partir de la paroi frontale et portant sur leur bord d'une part des languettes 606 s ' étendant l'une vers l'autre, et d'autre part des sabots 607,two ribs 602, 603 extending from the front wall and carrying on their edge on the one hand tongues 606 extending towards one another, and on the other hand shoes 607,
- deux ailes 605 s ' étendant obliquement à partir des bords de la paroi frontale et portant des lèvres 610 disposées en triangle et ménageant entr' elles une rainure longitudinale 611,two wings 605 extending obliquely from the edges of the front wall and carrying lips 610 arranged in a triangle and forming between them a longitudinal groove 611,
- des secondes languettes 91 s ' étendant à partir des nervures 602 et des ailes 605.- Second tongues 91 extending from the ribs 602 and the wings 605.
Le profilé plus large de la figure 14 comporte notamment : - une paroi frontale 401,The wider profile of FIG. 14 includes in particular: a front wall 401,
- deux ailes 405 s ' étendant obliquement à partir des bords de la paroi frontale et portant des lèvres 410 disposées en triangle et ménageant entr 'elles une rainure longitudinale 411, - trois nervures 402, 403, 404 s ' étendant à partir de la paroi frontale, entre les ailes 405, de manière que la distance entre l'une des nervures 404 et l'aile située du même côté soit supérieure à la distance entre la nervure 402 et l'autre aile, la nervure centrale 403 portant sur son bord deux languettes 406 et les deux autres nervures 403,404 portant sur leurs bords d'une part des languettes 406 et d'autre part des sabots 407, 408, les languettes 406 s ' étendant respectivement l'une vers l'autre, le sabot 407 s ' étendant à partir de la nervure 404 étant plus long que le sabot 408 s ' étendant à partir de la nervure 402, - des secondes languettes 91 s ' étendant à partir des nervures 402, 403, 404, et des ailes 405.- two wings 405 extending obliquely from the edges of the front wall and carrying lips 410 arranged in a triangle and forming between them a longitudinal groove 411, - three ribs 402, 403, 404 extending from the wall frontal, between the wings 405, so that the distance between one of the ribs 404 and the wing situated on the same side is greater than the distance between the rib 402 and the other wing, the central rib 403 bearing on its edge two tongues 406 and the other two ribs 403,404 carrying on their edges on the one hand tongues 406 and on the other hand shoes 407, 408, the tongues 406 extending respectively towards each other, the shoe 407 s 'extending from the rib 404 being longer than the shoe 408 extending from the rib 402, - Second tabs 91 extending from the ribs 402, 403, 404, and the wings 405.
Il suffit d'effectuer des découpes longitudinales, judicieusement situées, de ces profilés en PVC, pour obtenir tous les profilés requis décrits précédemment. Par exemple, pour le profilé de la figure 13 :It suffices to make longitudinal cuts, judiciously located, of these PVC profiles, to obtain all the required profiles described above. For example, for the profile in Figure 13:
- tel quel, il correspond au profilé recouvrant le montant central de la figure 2,- as is, it corresponds to the profile covering the central upright of Figure 2,
- coupé selon les lignes AA ou BB, on obtient les profilés 5 recouvrant les vantaux des figures 1 à 3, 6,- cut along lines AA or BB, the sections 5 covering the leaves of FIGS. 1 to 3, 6 are obtained,
7, 8,7, 8,
- coupé selon la ligne CC, on obtient le profilé des vantaux des figures 10 et 11.- cut along line CC, the profile of the leaves of Figures 10 and 11 is obtained.
Pour le profilé large de la figure 14, des coupes selon les lignes DD ou EE permettent d'obtenir les profilés recouvrant les dormants, la position de ces coupes, selon quelles conservent une plus ou moins grande partie du talon 407, permettant notamment d'adapter le profilé à la largeur exposée des éléments du cadre dormant d'origine, dans les cas de rénovations. La présence du talon 407 de plus grande largeur permet par exemple, par une découpe appropriée du profilé, d'insérer entre la paroi frontale et ce talon le bord, préalablement usiné de manière adéquate, d'une plaque de PVC destiné à recouvrir une paroi plus large que le cadre normal, telle que par exemple le soubassement d'une porte- fenêtre .For the wide section of FIG. 14, sections along the lines DD or EE make it possible to obtain the sections covering the frames, the position of these sections, depending on which retain a greater or lesser part of the heel 407, making it possible in particular to adapt the profile to the exposed width of the elements of the original frame, in the case of renovations. The presence of the heel 407 of greater width allows for example, by an appropriate cutting of the profile, to insert between the front wall and this heel the edge, previously machined adequately, of a PVC plate intended to cover a wall wider than the normal frame, such as for example the base of a French window.
La figure 12 illustre une variante préférée d'assemblage de profilés. Au lieu de 1 ' équerre 9 représentée figure 4, on utilise, ici, une ou des rondelles 92' en matière plastique, également insérées entres les nervures, ou entre une nervure et une aile du profilé, dans les gorges formées entre la face arrière de la paroi frontale et les secondes languettes 91. La découpe 93', correspondant au trou 93 de la rondelle, venant se loger sur l'angle vif formé par l'assemblage à l'onglet des profilés. Outre que ces demi-rondelles garantissent la co-planéité des parois frontales des profilés assemblés, elles présentent aussi l'avantage de permettre des assemblages avec des angles quelconques . Les demi-rondelles peuvent être collées, mais préférentiellement elles sont soudées par ultrasons, sur la face arrière des parois frontales comme représenté par les points de soudure 94. Un tel mode de fixation est particulièrement avantageux, car très rapide, sans risque de traces de colle, et sans marques sur la face visible des profilés.Figure 12 illustrates a preferred variant of profile assembly. Instead of the square 9 shown in FIG. 4, one or more washers 92 'of plastic material are used here, also inserted between the ribs, or between a rib and a wing of the profile, in the grooves formed between the rear face. of the front wall and the second tabs 91. The cutout 93 ′, corresponding to the hole 93 in the washer, which is housed on the sharp angle formed by the assembly at the profiles tab. Besides that these half-washers guarantee the co-flatness of the front walls of the assembled profiles, they also have the advantage of allowing assemblies with any angles. The half-washers can be glued, but preferably they are welded by ultrasound, on the rear face of the front walls as shown by the welding points 94. Such a method of fixing is particularly advantageous, because very fast, without risk of traces of glue, and without marks on the visible side of the profiles.
Comme on le voit figure 12, l'assemblage peut encore être consolidé par des rondelles entières 92, fixées également par soudure par ultrasons, sur les languettes 406, 506. Les rondelles débordent à l'arrière du profilé, ceci n'étant cependant pas gênant dans la mesure où l'épaisseur des rondelles 92 est inférieure à l'espacement entre les profilés et le bois, c'est-à-dire à l'épaisseur de la partie polygonale 71 des plots 7. L'invention n'est pas limitée aux exemples décrits précédemment. Elle pourra notamment être appliquée pour le revêtement d'autres types de menuiseries, qu'elles soient à structure en bois, métal ou plastique. Les profilés du type selon 1 ' invention pourront également être utilisés pour le revêtement d'autres éléments de structure dans la menuiserie de bâtiment, en particulier pour des vérandas . As can be seen in FIG. 12, the assembly can also be consolidated by whole washers 92, also fixed by ultrasonic welding, on the tongues 406, 506. The washers project beyond the rear of the profile, this however not bothersome insofar as the thickness of the washers 92 is less than the spacing between the profiles and the wood, that is to say the thickness of the polygonal part 71 of the studs 7. The invention is not limited to the examples described above. It can in particular be applied for the coating of other types of joinery, whether they are of wood, metal or plastic structure. Profiles of the type according to the invention can also be used for coating other structural elements in building joinery, in particular for verandas.
