Description

La présente invention a pour objet un dispositif de fenêtre.The present invention relates to a window device.

Le châssis est, dans une fenêtre, le cadre rigide qui supporte le vitrage. La partie fixe d'une fenêtre est appelée dormant, tandis que la partie mobile est l'ouvrant.The sash is, in a window, the rigid frame that supports the glazing. The fixed part of a window is called the frame, while the moving part is the sash.

Les fenêtres traditionnelles sont classées par grandes familles liées aux matériaux des châssis. On distingue habituellement les châssis en bois, les châssis en PVC (polyvinyl chloride en langue anglaise), les châssis en aluminium, les châssis en acier, ou encore les châssis mixtes bois-aluminium.Traditional windows are classified by major families related to the materials of the frames. A distinction is usually made between wooden frames, PVC frames (polyvinyl chloride in English), aluminum frames, steel frames, or mixed wood-aluminum frames.

Les logements individuels ou collectifs utilisent principalement des châssis en bois, en PVC, et dans une moindre mesure des châssis en aluminium et des châssis mixte bois-aluminium pour des logements de moyenne et haut de gamme. Les bâtiments de bureaux utilisent principalement des châssis en aluminium. Les châssis en acier sont utilisés pour des applications spécifiques (contrainte pare-feu ou pare-balle par exemple) ou pour des projets au style industriel marqué.Individual or collective housing mainly uses wooden frames, PVC frames, and to a lesser extent aluminum frames and mixed wood-aluminum frames for medium and high-end housing. Office buildings mainly use aluminum frames. Steel frames are used for specific applications (fireproof or bulletproof constraints, for example) or for projects with a marked industrial style.

Les châssis en aluminium se classifient en plusieurs types en fonction de la « masse vue » visible au droit des ouvrants. On connaît ainsi les châssis en aluminium pour un ouvrant traditionnel (ou « ouvrant visible »), les châssis en aluminium du type « ouvrant caché » parclosé, ou encore les châssis en aluminium du type « ouvrant caché » collé VEC (pour vitrage extérieur collé).Aluminum frames are classified into several types depending on the "mass seen" visible to the right of the openings. We thus know the aluminum frames for a traditional opening (or “visible opening”), the aluminum frames of the parclosed “hidden opening” type, or the aluminum frames of the “hidden opening” type glued VEC (for glued exterior glazing).

Différents types d'ouvrant peuvent être utilisés.Different types of opening can be used.

Tel qu'illustré à la figure 1, un dispositif de fenêtre 1 comprend un dormant 2, qui est la partie de menuiserie fixe du dispositif 1, et un ouvrant 3, qui est la partie mobile du dispositif 1. Le dispositif de fenêtre 1 de la figure 1 est un ouvrant visible à la française, qui s'ouvre de manière verticale, vers l'intérieur du bâtiment, tel que représenté par les traits en pointillé. L'ouvrant 3 contient un cadre de menuiserie (un châssis) visible de l'extérieur. Des parties vitrées fixes peuvent aussi faire partie de la fenêtre.As illustrated at figure 1 , a window device 1 comprises a frame 2, which is the fixed carpentry part of the device 1, and an opening 3, which is the movable part of the device 1. The window device 1 of the figure 1 is a visible French opening, which opens vertically, towards the interior of the building, as represented by the dotted lines. The opening 3 contains a carpentry frame (a frame) visible from the outside. Fixed glazed parts can also be part of the window.

Le dispositif 1 de la figure 2 est un ouvrant caché à la française, dans lequel le cadre de menuiserie de l'ouvrant est caché depuis l'extérieur.Device 1 of the figure 2 is a concealed French sash, in which the sash joinery frame is hidden from the outside.

Un dispositif de fenêtre 1 du type ouvrant à l'italienne s'ouvre de manière horizontale, vers l'extérieur de l'habitation (figure 3). Aucune menuiserie n'est visible depuis l'extérieur, seul un joint creux de 2 cm environ sépare les vitrages. Vues depuis l'intérieur, les menuiseries sont plus larges.A window device 1 of the Italian opening type opens horizontally, towards the outside of the dwelling ( picture 3 ). No carpentry is visible from the outside, only a hollow joint of about 2 cm separates the glazing. Seen from the inside, the joinery is wider.

Dans un ouvrant de type « verre-verre » à la française, illustré à la figure 4, seul un joint creux, par exemple de 1 cm environ, sépare les vitrages depuis l'intérieur et l'extérieur.In a French-style “glass-glass” type sash, illustrated in figure 4 , only a hollow joint, for example of about 1 cm, separates the glazing from the inside and the outside.

La suite de la description est notamment consacrée à ce dispositif de fenêtre de type ouvrant « verre-verre ».The remainder of the description is particularly devoted to this window device of the “glass-glass” opening type.

Depuis l'émergence de contraintes d'isolation thermique sur les bâtiments dans les années 1990, les doubles et triples vitrages ainsi que les menuiseries (tout ce qui n'est pas vitrage) à rupture de pont thermique se sont démocratisés, modifiant ainsi durablement l'architecture contemporaine. Ces menuiseries se sont complexifiées en intégrant des contraintes d'isolation thermique, acoustique, d'étanchéité à l'air, à l'eau et de robustesse dans le temps ; par conséquence leur « masse vue », c'est-à-dire leur largeur visible depuis l'intérieur et l'extérieur, est aujourd'hui considérable. Cette « masse vue » importante et la visibilité même des menuiseries depuis l'intérieur et l'extérieur constituent un sujet esthétique majeur de l'architecture actuelle.Since the emergence of thermal insulation constraints on buildings in the 1990s, double and triple glazing as well as joinery (everything that is not glazed) with thermal break have been democratized, thus modifying contemporary architecture in the long term. These joineries have become more complex by integrating thermal and acoustic insulation constraints, airtightness, watertightness and robustness over time; consequently their "mass seen", that is to say their width visible from the inside and the outside, is today considerable. This significant “seen mass” and the very visibility of the woodwork from the inside and the outside constitute a major aesthetic subject of current architecture.

Il apparaît ainsi souhaitable de disposer d'un dispositif de fenêtre qui présente une homogénéité d'aspect entre les parties ouvrantes et des dormantes des façades vitrées et qui permette de réduire la « masse vue » des menuiseries, tout en garantissant de bonnes performances techniques de l'ensemble menuisé équivalentes voire meilleures.It thus appears desirable to have a window device which presents a homogeneity of appearance between the opening parts and the fixed parts of the glazed facades and which makes it possible to reduce the “mass seen” of the joinery, while guaranteeing good technical performance of the joinery unit equivalent or even better.

EP2378044A2 divulgue un dispositif de fenêtre, comprenant une partie fixe appelée dormant et une partie mobile appelée ouvrant apte à se refermer sur le dormant, où le dormant comprend un triple vitrage et l'ouvrant comprend un triple vitrage. EP2378044A2 discloses a window device, comprising a fixed part called the frame and a movable part called the sash able to close on the frame, where the frame comprises triple glazing and the sash comprises triple glazing.

La présente invention vise à atteindre ces objectifs.The present invention aims to achieve these objectives.

L'invention a ainsi pour objet un dispositif de fenêtre selon la revendication 1.The invention thus relates to a window device according to claim 1.

En outre, il n'y a pas de châssis à l'extérieur du vitrage externe de l'ouvrant et il n'y a pas de châssis à l'intérieur du vitrage interne de l'ouvrant.In addition, there is no frame outside the outer glazing of the sash and there is no frame inside the inner glazing of the sash.

Le dispositif selon l'invention permet de constituer un ouvrant à la « masse vue » nulle depuis l'extérieure et depuis l'intérieure. La « frappe de l'ouvrant », c'est-à-dire le recouvrement de l'ouvrant sur le dormant, nécessaire pour une bonne étanchéité, est assurée par le décalage des bords des différents verres d'un triple vitrage isolant.The device according to the invention makes it possible to form an opening with zero “seen mass” from the outside and from the inside. The "strike of the opening", that is to say the covering of the opening on the frame, necessary for a good seal, is ensured by the offset of the edges of the different glasses of a triple insulating glazing.

Le vitrage fixe du dormant est à bords décalés entourant toute ou une partie de la périphérie de l'ouvrant.The fixed glazing of the frame has staggered edges surrounding all or part of the periphery of the opening.

Le dispositif est applicable à différents types d'ouvrants :

  • ouvrant à la française
  • ouvrant oscillo-battant
  • ouvrant à soufflet haut
  • ouvrant à l'anglaise
  • ouvrant à l'italienne
  • ouvrant à projection parallèle (ou « pantographe »)
  • ouvrant à l'australienne.
The device is applicable to different types of opening:
  • French opening
  • tilt and turn sash
  • high bellows sash
  • English opening
  • Italian opening
  • parallel projection sash (or "pantograph")
  • opening to the Australian.

L'intérêt d'un ouvrant à la masse menuisée nulle depuis l'extérieure et depuis l'intérieure est né des nombreuses contraintes entourant les ouvrants. Ces contraintes sont notamment :

  • l'intégration architecturale : afin de garantir une intégration réussie des ouvrants, les concepteurs des bâtiments cherchent à minimiser la « masse vue » des menuiseries depuis l'extérieur et depuis l'intérieur afin de maximiser l'apport de lumière naturelle et donner une écriture légère à la façade. De plus, on cherche esthétiquement à homogénéiser les matériaux visibles en façade pour en simplifier la lecture. Les différents types d'ouverture (ouverture à la française, à l'italienne, oscillo-battant, etc.), les différents matériaux (menuiseries aciers, bois, aluminium, VEC (vitrage extérieur collé)) présentent des avantages ou des inconvénients pour ces différents sujets ;
  • une contrainte réglementaire : L'arrêté du 24 décembre 2014 modifiant la Règlementation Thermique 2012 (RT 2012) impose une surface d'ouvrant de confort en façade d'au moins 30% de la surface des baies pour tout bâtiment de bureau ou de logement. Cet arrêté rend obligatoire la présence d'ouvrant et impose leur superficie ;
  • les contraintes de luminosité : Le « Facteur de Lumière de Jour » (FLJ) ou l'« autonomie lumineuse », liés aux certifications et aux labels visés par les projets et aux habitudes de conception contemporaines des bâtiments de bureau imposent des surfaces vitrées très importantes en façade (de 60 à 80 % de baie sur la surface extérieure de façade) ;
  • les contraintes de garde-corps : aucun ouvrant n'est toléré en dessous d'un mètre du sol, cette partie ne peut pas faire partie de l'ouvrant.
The interest of an opening with zero carpentry mass from the outside and from the inside was born from the many constraints surrounding the opening. These constraints include:
  • architectural integration: in order to guarantee successful integration of the openings, the building designers seek to minimize the “seen mass” of the woodwork from the outside and from the inside in order to maximize the contribution of natural light and give a light character to the facade. In addition, aesthetically we seek to homogenize the materials visible on the facade to simplify reading. The different types of opening (French opening, Italian opening, tilt and turn, etc.), the different materials (steel, wood, aluminum joinery, VEC (glued exterior glazing)) have advantages or disadvantages for these different subjects;
  • a regulatory constraint: The decree of December 24, 2014 amending the 2012 Thermal Regulations (RT 2012) imposes a comfort opening surface on the facade of at least 30% of the surface of the openings for any building of office or accommodation. This decree makes mandatory the presence of opening and imposes their surface;
  • luminosity constraints: The "Daylight Factor" (FLJ) or "light autonomy", linked to the certifications and labels targeted by the projects and to the contemporary design habits of office buildings, impose very large glazed surfaces on the facade (from 60 to 80% of windows on the exterior surface of the facade);
  • guardrail constraints: no opening is tolerated below one meter from the ground, this part cannot be part of the opening.

Le dormant comprend un triple vitrage, dont une vitre externe, une vitre intermédiaire et une vitre interne.The frame includes triple glazing, including an external pane, an intermediate pane and an internal pane.

La vitre externe du dormant s'étend longitudinalement en direction de l'ouvrant au-delà des extrémités longitudinales verticales de la vitre intermédiaire et de la vitre interne du dormant situées du côté de l'ouvrant.The external pane of the fixed frame extends longitudinally in the direction of the opening beyond the vertical longitudinal ends of the intermediate pane and of the internal pane of the fixed frame located on the side of the opening.

La vitre externe du dormant peut être alignée avec la vitre externe de l'ouvrant, la vitre intermédiaire du dormant peut être alignée avec la vitre intermédiaire de l'ouvrant, et la vitre interne du dormant peut être alignée avec la vitre interne de l'ouvrant.The external frame pane can be aligned with the external pane of the sash, the intermediate pane of the frame can be aligned with the intermediate pane of the sash, and the internal pane of the frame can be aligned with the internal pane of the sash.

L'extrémité longitudinale verticale de la vitre intermédiaire du dormant située du côté de l'ouvrant est coplanaire avec l'extrémité longitudinale verticale de la vitre interne du dormant située du côté de l'ouvrant, et l'extrémité longitudinale verticale de la vitre intermédiaire de l'ouvrant située du côté du dormant est coplanaire avec l'extrémité longitudinale verticale de la vitre externe de l'ouvrant située du côté du dormant.The vertical longitudinal end of the intermediate pane of the frame located on the side of the frame is coplanar with the vertical longitudinal end of the internal pane of the frame located on the side of the frame, and the vertical longitudinal end of the intermediate pane of the frame located on the side of the frame is coplanar with the vertical longitudinal end of the external pane of the frame located on the side of the frame.

Un premier joint, appelé premier joint du dormant, est disposé verticalement contre l'extrémité longitudinale verticale de la vitre intermédiaire du dormant située du côté de l'ouvrant et contre l'extrémité longitudinale verticale de la vitre interne du dormant située du côté de l'ouvrant, et un premier joint, appelé premier joint de l'ouvrant, est disposé verticalement contre l'extrémité longitudinale verticale de la vitre intermédiaire de l'ouvrant située du côté du dormant et contre l'extrémité longitudinale verticale de la vitre externe de l'ouvrant située du côté du dormant.A first seal, called the first seal of the frame, is arranged vertically against the vertical longitudinal end of the intermediate pane of the frame located on the side of the frame and against the vertical longitudinal end of the internal pane of the frame located on the side of the frame, and a first seal, called the first seal of the frame, is placed vertically against the vertical longitudinal end of the intermediate pane of the frame located on the side of the frame and against the vertical longitudinal end of the external pane of the frame located on the side of the frame.

Chaque premier joint est un joint sapin.Each first joint is a tree joint.

Le dormant est muni d'un profilé, appelé profilé du dormant, et disposé verticalement, du côté de l'ouvrant, contre le premier joint du dormant, et l'ouvrant est muni d'un profilé, appelé profilé de l'ouvrant, et disposé verticalement, du côté du dormant, contre le premier joint de l'ouvrant, chaque profilé pouvant être muni d'une gorge d'intégration destinée à accueillir une partie du système de fermeture, ladite gorge étant située dans la zone de recouvrement.The frame is provided with a profile, called frame profile, and arranged vertically, on the side of the opening, against the first joint of the frame, and the opening is provided with a profile, called profile of the opening, and arranged vertically, on the side of the frame, against the first joint of the opening, each profile being able to be provided with an integration groove intended to accommodate part of the closing system, said groove being located in the overlap zone.

Le profilé du dormant peut être muni d'un joint d'étanchéité qui est en contact avec la vitre interne de l'ouvrant et le profilé de l'ouvrant peut être muni d'un joint d'étanchéité qui est contact avec la vitre externe du dormant.The profile of the frame can be provided with a seal which is in contact with the internal pane of the sash and the profile of the sash can be provided with a seal which is in contact with the external pane of the frame.

Le profilé du dormant peut être muni d'une mousse isolante qui est en contact avec le profilé du dormant et avec la vitre externe du dormant.The profile of the frame can be provided with an insulating foam which is in contact with the profile of the frame and with the outer pane of the frame.

Pour assurer une bonne isolation du dispositif, le profilé du dormant peut comprendre une surface transversale d'appui qui s'étend le long du premier joint du dormant, entre la vitre externe du dormant et la vitre interne du dormant, et qui s'étend le long de l'épaisseur de la vitre interne du dormant, et le profilé de l'ouvrant peut comprendre une surface transversale d'appui qui s'étend le long du premier joint de l'ouvrant, entre la vitre interne de l'ouvrant et la vitre externe de l'ouvrant, et qui s'étend le long de l'épaisseur de la vitre externe de l'ouvrantTo ensure good insulation of the device, the profile of the fixed frame may comprise a transverse bearing surface which extends along the first joint of the fixed frame, between the external pane of the fixed frame and the internal pane of the fixed frame, and which extends along the thickness of the internal pane of the fixed frame, and the profile of the sash may include a transverse bearing surface which extends along the first joint of the sash, between the internal pane of the sash and the external pane of the sash, and which extends along the thickness of the outer pane of the sash

Un deuxième joint, appelé deuxième joint du dormant ou joint de scellement, peut être disposé verticalement contre le premier joint du dormant et s'étend verticalement entre la vitre interne du dormant et la vitre intermédiaire du dormant, ainsi qu'entre la vitre intermédiaire du dormant et la vitre externe du dormant, et un deuxième joint, appelé deuxième joint de l'ouvrant, peut être disposé verticalement contre le premier joint de l'ouvrant et s'étendre verticalement entre la vitre interne de l'ouvrant et la vitre intermédiaire de l'ouvrant, ainsi qu'entre la vitre intermédiaire de l'ouvrant et la vitre externe de l'ouvrant.A second seal, called the second frame seal or seal, can be placed vertically against the first frame seal and extends vertically between the inner frame pane and the intermediate frame pane, as well as between the intermediate frame pane and the outer frame pane, and a second seal, called the second sash seal, can be placed vertically against the first sash seal and extend vertically between the inner sash pane and the intermediate sash pane, as well as between the intermediate pane of the sash and the outer pane of the sash.

Un espaceur peut être disposé verticalement contre chaque deuxième joint du dormant et contre chaque deuxième joint de l'ouvrant, chaque espaceur présentant une extrémité longitudinale située du côté du deuxième joint, ainsi qu'une extrémité longitudinale éloignée du deuxième joint, les extrémités longitudinales éloignées du deuxième joint et situées dans le dormant étant alignées, les extrémités longitudinales éloignées du deuxième joint et situées dans l'ouvrant étant alignées, la distance longitudinale entre les extrémités longitudinales éloignées du deuxième joint et situées dans le dormant et les extrémités longitudinales éloignées du deuxième joint et situées dans l'ouvrant étant avantageusement inférieure à 0,085 m, de manière à assurer à la fois une bonne isolation thermique et une bonne étanchéité du dispositif.A spacer can be arranged vertically against each second seal of the fixed frame and against each second seal of the sash, each spacer having a longitudinal end located on the side of the second seal, thus a longitudinal end remote from the second seal, the longitudinal ends remote from the second seal and located in the frame being aligned, the longitudinal ends remote from the second seal and located in the opening being aligned, the longitudinal distance between the longitudinal ends remote from the second seal and located in the frame and the longitudinal ends remote from the second seal and located in the opening being advantageously less than 0.085 m, so as to ensure both good thermal insulation and good sealing of the device.

DESCRIPTION DETAILLEEDETAILED DESCRIPTION

Tel qu'illustré aux figures 5 à 7, un dispositif de fenêtre 10 selon l'invention comprend une partie fixe 2, appelée dormant, et une partie mobile 3, appelée ouvrant. Le dormant 2 est la partie scellée au mur de manière étanche, tandis que l'ouvrant 3 est la partie mobile qui refermée doit assurer en façade l'étanchéité aux intempéries et au bruit. Le dormant 2 et l'ouvrant 3 sont constitués chacun d'un triple vitrage, tel que représenté, ou alternativement dans un mode de réalisation ne faisant pas partie de l'invention d'un triple vitrage pour l'ouvrant 3 et d'un double vitrage pour le dormant 2. Le dormant 2 et l'ouvrant 3 sont en outre intégrés chacun à un montant de façade 11.As illustrated in figures 5 to 7 , a window device 10 according to the invention comprises a fixed part 2, called the frame, and a movable part 3, called the opening. The frame 2 is the part sealed to the wall in a watertight manner, while the opening 3 is the movable part which, when closed, must ensure weather and noise tightness on the facade. The fixed frame 2 and the opening 3 each consist of triple glazing, as shown, or alternatively in an embodiment not forming part of the invention of triple glazing for the opening 3 and double glazing for the fixed frame 2. The fixed frame 2 and the opening 3 are also each integrated into a front upright 11.

Les vitrages du dormant 2 et de l'ouvrant 3 sont disposés verticalement en configuration opérationnelle du dispositif 10. On utilisé un repère orthonormé (X,Y,Z), l'axe Z désignant la verticale, le plan XY étant un plan horizontal, le plan XZ étant le plan vertical des vitrages. Les figures 6 et 7 sont ainsi des vues du dispositif 10 en coupe horizontale dans un plan XY. Les vitrages sont d'orientation longitudinale dans cette coupe horizontale du dispositif 10.The glazings of the frame 2 and of the opening 3 are arranged vertically in the operational configuration of the device 10. An orthonormal reference (X,Y,Z) is used, the Z axis designating the vertical, the XY plane being a horizontal plane, the XZ plane being the vertical plane of the glazing. THE figure 6 And 7 are thus views of the device 10 in horizontal section in an XY plane. The glazing is of longitudinal orientation in this horizontal section of the device 10.

Le dormant 2 comprend ainsi une vitre externe 2a, une vitre intermédiaire 2b et une vitre interne 2c. L'extérieur est défini comme étant le côté extérieur du bâtiment et l'intérieur comme étant le côté intérieur au bâtiment. Une poignée 12 permet d'actionner un système de fermeture de l'ouvrant 3 sur le dormant 2. Sur la figure 6, l'ouvrant 3 est illustré en position fermée, ainsi qu'en position ouverte 3'.The frame 2 thus comprises an outer pane 2a, an intermediate pane 2b and an inner pane 2c. The exterior is defined as the exterior side of the building and the interior as the interior side of the building. A handle 12 makes it possible to actuate a system for closing the opening 3 on the frame 2. On the figure 6 , the opening 3 is illustrated in the closed position, as well as in the open position 3'.

De la même façon, l'ouvrant 3 comprend une vitre externe 3a, une vitre intermédiaire 3b et une vitre interne 3c. La vitre externe 3a de l'ouvrant est alignée avec la vitre externe 2a du dormant, la vitre intermédiaire 3b de l'ouvrant 3 est alignée avec la vitre intermédiaire 2b du dormant 2 et la vitre interne 3c de l'ouvrant 3 est alignée avec la vitre interne 2c du dormant.Similarly, the opening 3 comprises an outer pane 3a, an intermediate pane 3b and an inner pane 3c. The outer pane 3a of the sash is aligned with the outer pane 2a of the frame, the intermediate pane 3b of the sash 3 is aligned with the intermediate pane 2b of the frame 2 and the inner pane 3c of the sash 3 is aligned with the inner pane 2c of the frame.

Les termes « intérieur », « interne », « extérieur » et « externe » sont définis relativement à l'axe Y. Ainsi, on trouve successivement, depuis l'intérieur vers l'extérieur, la poignée 12, la vitre interne 3c, la vitre intermédiaire 3b et la vitre externe 3a.The terms "interior", "internal", "exterior" and "external" are defined relative to the Y axis. Thus, we find successively, from the interior towards the outside, the handle 12, the inner pane 3c, the intermediate pane 3b and the outer pane 3a.

La « frappe » de l'ouvrant, c'est-à-dire le recouvrement de l'ouvrant 3 sur le dormant 2, nécessaire pour une bonne étanchéité, est assurée par un décalage des bords des différentes vitres de l'ouvrant 3 et du dormant 2. En particulier, l'extrémité longitudinale 2c1 de la vitre interne 2c du dormant 2 située du côté de l'ouvrant 3, qui forme une face verticale dans un plan transversal YZ, et l'extrémité longitudinale 2b1 de la vitre intermédiaire 2b du dormant 2 située du côté de l'ouvrant 3, qui forme une face verticale dans un plan transversal YZ, sont coplanaires, tandis que la vitre externe 2a s'étend, dans la direction horizontale longitudinale X et en direction de la vitre externe 3a de l'ouvrant 3, au-delà du plan de ces extrémités. Ainsi, l'extrémité longitudinale verticale 2a1 est plus proche de l'ouvrant 3 que les extrémités verticales longitudinales 2b1, 2c1.The "strike" of the sash, that is to say the covering of the sash 3 on the frame 2, necessary for good sealing, is ensured by a shift of the edges of the different panes of the sash 3 and of the frame 2. intermediate 2b of the frame 2 located on the side of the opening 3, which forms a vertical face in a transverse plane YZ, are coplanar, while the outer pane 2a extends, in the longitudinal horizontal direction X and in the direction of the outer pane 3a of the opening 3, beyond the plane of these ends. Thus, the vertical longitudinal end 2a1 is closer to the opening 3 than the longitudinal vertical ends 2b1, 2c1.

De la même façon, l'extrémité longitudinale 3a1 de la vitre externe 3a de l'ouvrant 3 située du côté du dormant 2, qui forme une face verticale dans un plan transversal YZ, et l'extrémité longitudinale 3b1 de la vitre intermédiaire 3b de l'ouvrant 3 située du côté du dormant 2, qui forme une face verticale dans un plan transversal YZ, sont alignées, tandis que la vitre interne 3c s'étend, dans la direction horizontale longitudinale X et en direction de la vitre interne 2c1 du dormant 2, au-delà du plan de ces extrémités. Ainsi, l'extrémité longitudinale verticale 3c1 est plus proche du dormant 2 que les extrémités verticales longitudinales 3a1, 3b1.In the same way, the longitudinal end 3a1 of the outer pane 3a of the sash 3 located on the side of the frame 2, which forms a vertical face in a transverse plane YZ, and the longitudinal end 3b1 of the intermediate pane 3b of the sash 3 located on the side of the frame 2, which forms a vertical face in a transverse plane YZ, are aligned, while the inner pane 3c extends, in the longitudinal horizontal direction X and in the direction of the pane internal 2c1 of the frame 2, beyond the plane of these ends. Thus, the vertical longitudinal end 3c1 is closer to the frame 2 than the longitudinal vertical ends 3a1, 3b1.

Ainsi, la vitre externe 2a du dormant 2 et la vitre interne 3c de l'ouvrant 3 présentent une zone de recouvrement longitudinal R.Thus, the outer pane 2a of the frame 2 and the inner pane 3c of the opening 3 have a longitudinal overlap zone R.

La figure 7 illustre plus en détail la structure et la menuiserie situées entre les triple vitrages du dormant 2 et de l'ouvrant 3.There figure 7 illustrates in more detail the structure and joinery located between the triple glazing of frame 2 and sash 3.

Du côté de l'extrémité longitudinale du dormant 2 située du côté de l'ouvrant 3, le dormant 2 comprend un espaceur transversal 4, qui s'étend verticalement et transversalement, dans un plan YZ, entre la vitre externe 2a et la vitre intermédiaire 2b, ainsi qu'entre la vitre intermédiaire 2b et la vitre interne 2c. Dans la direction longitudinale X, chaque espaceur transversal 4 comprend une extrémité 4a éloignée de la zone de recouvrement R.On the side of the longitudinal end of the frame 2 located on the side of the opening 3, the frame 2 comprises a transverse spacer 4, which extends vertically and transversely, in a YZ plane, between the outer pane 2a and the intermediate pane 2b, as well as between the intermediate pane 2b and the internal pane 2c. In the longitudinal direction X, each transverse spacer 4 comprises an end 4a remote from the overlap zone R.

L'espaceur 4 peut être en polyamide avec un dessicant pour éviter la condensation. Attenant à l'espaceur 4, un joint de scellement 5, typiquement en silicone, est disposé transversalement entre la vitre externe 2a et la vitre intermédiaire 2b, ainsi qu'entre la vitre intermédiaire 2b et la vitre interne 2c. L'extrémité longitudinale des joints 5 située du côté de l'ouvrant 3 est avantageusement alignée avec l'extrémité longitudinale 2b1 de la vitre intermédiaire 2b et l'extrémité longitudinale 2c1 de la vitre interne 2c.The spacer 4 can be made of polyamide with a desiccant to prevent condensation. Adjoining the spacer 4, a seal 5, typically made of silicone, is arranged transversely between the outer pane 2a and the intermediate pane 2b, as well as between the intermediate pane 2b and the inner pane 2c. The longitudinal end of the seals 5 located on the side of the opening 3 is advantageously aligned with the longitudinal end 2b1 of the intermediate pane 2b and the longitudinal end 2c1 of the internal pane 2c.

Chaque espaceur 4 comprend une extrémité longitudinale 4a située du côté du joint de scellement 5, l'extrémité longitudinale 4a formant une face verticale dans un plan transversal YZ, ainsi qu'une extrémité longitudinale 4b éloignée du joint de scellement 5, l'extrémité longitudinale 4b formant une face verticale dans un plan transversal YZ. Les extrémités longitudinales 4a des espaceurs 4 du dormant 2 sont avantageusement alignées, et les extrémités longitudinales 4b des espaceurs 4 du dormant 2 sont avantageusement alignées. De la même façon, les extrémités longitudinales 4a des espaceurs 4 de l'ouvrant 3 sont avantageusement alignées, et les extrémités longitudinales 4b des espaceurs 4 de l'ouvrant 3 sont avantageusement alignées.Each spacer 4 comprises a longitudinal end 4a located on the side of the seal 5, the longitudinal end 4a forming a vertical face in a transverse plane YZ, as well as a longitudinal end 4b remote from the seal 5, the longitudinal end 4b forming a vertical face in a transverse plane YZ. The longitudinal ends 4a of the spacers 4 of the frame 2 are advantageously aligned, and the longitudinal ends 4b of the spacers 4 of the frame 2 are advantageously aligned. Similarly, the longitudinal ends 4a of the spacers 4 of the opening 3 are advantageously aligned, and the longitudinal ends 4b of the spacers 4 of the opening 3 are advantageously aligned.

En appui contre l'extrémité longitudinale 2b1 de la vitre intermédiaire 2b et l'extrémité longitudinale 2c1 de la vitre interne 2c du dormant 2 est disposé un joint transversal 6, par exemple un joint sapin pour une meilleure ventilation. Le joint sapin 6 reprend les tolérances de fabrication des vitrages et permet d'assurer l'étanchéité entre la vitre interne 2c du dormant 2 et la vitre interne 3c de l'ouvrant 3.Resting against the longitudinal end 2b1 of the intermediate window 2b and the longitudinal end 2c1 of the inner window 2c of the frame 2 is placed a transverse joint 6, for example a fir tree joint for better ventilation. The fir tree seal 6 takes up the manufacturing tolerances of the glazing and makes it possible to ensure the seal between the internal pane 2c of the frame 2 and the internal pane 3c of the opening 3.

A la droite du joint sapin 6 du dormant 2, du côté de l'ouvrant 3, se situe un profilé 7a du dormant. Le profilé 7a du dormant, en matériau polyamide, en fibre de verre, en profilé pultrudé, en PVC, en aluminium, en acier carbone, ou encore en acier inoxydable, intègre un ou plusieurs joints d'étanchéité 8, une gorge 9 d'intégration de quincaillerie, et un système de solidarisation de l'ouvrant 3 au dormant 2. Le profilé 7a facilite l'évacuation des éventuelles eaux de ruissellement et des eaux de son condensation par sa forme, ses joints et d'éventuels orifices. Le profilé 7a du dormant 2 peut comprendre un joint d'étanchéité 8 qui est en contact avec la vitre interne 3c de l'ouvrant 3. Le profilé 7a du dormant peut être muni d'une mousse isolante 14, par exemple en mousse EPDM. Les caoutchoucs EPDM (sigle de éthylène-propylène-diène monomère) sont des élastomères spéciaux. Ces terpolymères amorphes peuvent être obtenus en copolymérisant dans des proportions variables l'éthylène (le terpolymère contient de 60 à 85 % de motifs éthylène) et le propylène, avec un faible taux de diène non conjugué. La mousse isolante 14 est en contact avec le profilé 7b de l'ouvrant 3 et avec la vitre externe 2a du dormant. La mousse 14 permet de limiter les échanges radiatifs au sein de la cavité de la zone de recouvrement R. De plus, la mousse 14 forme une frappe supplémentaire, ce qui améliore l'étanchéité du dispositif 10 à l'air et à l'eau.To the right of the tree joint 6 of the frame 2, on the side of the opening 3, is a section 7a of the frame. The profile 7a of the frame, made of polyamide material, fiberglass, pultruded profile, PVC, aluminum, carbon steel, or even stainless steel, incorporates one or more seals 8, a groove 9 for integrating hardware, and a system for securing the opening 3 to the frame 2. The profile 7a facilitates the evacuation of any runoff water and water from its condensation by its shape, its joints and any holes. The profile 7a of the frame 2 may include a seal 8 which is in contact with the inner pane 3c of the opening 3. The profile 7a of the frame may be provided with an insulating foam 14, for example made of EPDM foam. EPDM (abbreviation for ethylene-propylene-diene monomer) rubbers are special elastomers. These amorphous terpolymers can be obtained by copolymerizing in variable proportions ethylene (the terpolymer contains 60 to 85% of ethylene units) and propylene, with a low content of non-conjugated diene. The insulating foam 14 is in contact with the profile 7b of the opening 3 and with the outer pane 2a of the frame. The foam 14 makes it possible to limit the radiative exchanges within the cavity of the overlap zone R. In addition, the foam 14 forms an additional impact, which improves the tightness of the device 10 to air and to water.

Le profilé du dormant 7a comprend une surface transversale d'appui 7a1 qui s'étend le long du premier joint 6 du dormant 2, entre la vitre externe 2a du dormant 2 et la vitre interne 2c du dormant 2, et qui s'étend sur l'épaisseur de la vitre interne 2c du dormant 2.The profile of the frame 7a comprises a transverse bearing surface 7a1 which extends along the first joint 6 of the frame 2, between the external pane 2a of the frame 2 and the internal pane 2c of the frame 2, and which extends over the thickness of the internal pane 2c of the frame 2.

Ainsi, de gauche à droite du dormant 2, c'est-à-dire longitudinalement en direction de l'ouvrant 3, on trouve l'espaceur 4, le joint en silicone 5, le joint sapin 6 et le profilé 7a du dormant 2.Thus, from left to right of the frame 2, that is to say longitudinally in the direction of the opening 3, there is the spacer 4, the silicone seal 5, the fir tree seal 6 and the profile 7a of the frame 2.

De la même façon, par symétrie, du côté de l'extrémité longitudinale de l'ouvrant 3 située du côté du dormant 2, l'ouvrant 3 comprend un espaceur transversal 4, situé entre la vitre externe 3a et la vitre intermédiaire 3b, ainsi qu'entre la vitre intermédiaire 3b et la vitre interne 3c. Attenant à l'espaceur 4, un joint 5, typiquement en silicone, est disposé transversalement entre la vitre externe 3a et la vitre intermédiaire 3b, ainsi qu'entre la vitre intermédiaire 3b et la vitre interne 3c. L'extrémité longitudinale du joint 5 située du côté du dormant 2 est avantageusement alignée (coplanaire) avec l'extrémité longitudinale 3b1 de la vitre intermédiaire 3b et l'extrémité longitudinale 3a1 de la vitre externe 3a.In the same way, by symmetry, on the side of the longitudinal end of the opening 3 located on the side of the frame 2, the opening 3 comprises a transverse spacer 4, located between the outer pane 3a and the intermediate pane 3b, as well as between the intermediate pane 3b and the internal pane 3c. Adjoining the spacer 4, a seal 5, typically made of silicone, is arranged transversely between the outer pane 3a and the intermediate pane 3b, as well as between the intermediate pane 3b and the inner pane 3c. The longitudinal end of seal 5 located on the side of frame 2 is advantageously aligned (coplanar) with longitudinal end 3b1 of intermediate pane 3b and longitudinal end 3a1 of outer pane 3a.

En appui contre l'extrémité longitudinale de la vitre intermédiaire 3b et de la vitre externe 3a de l'ouvrant 3 est disposé un joint transversal 6, par exemple un joint sapin pour une meilleure ventilation. Le joint sapin 6 reprend les tolérances de fabrication des vitrages et permet d'assurer l'étanchéité entre la vitre externe 2a du dormant 2 et la vitre externe 3a de l'ouvrant 3.Resting against the longitudinal end of the intermediate pane 3b and of the outer pane 3a of the opening 3 is arranged a transverse seal 6, for example a fir seal for better ventilation. The fir 6 seal takes up the tolerances manufacture of the glazings and makes it possible to ensure the seal between the outer pane 2a of the frame 2 and the outer pane 3a of the opening 3.

A la gauche du joint sapin 6 de l'ouvrant 3 se situe un profilé 7b de l'ouvrant 3. Le profilé 7, en matériau polyamide, en fibre de verre, en profilé pultrudé, en PVC, en aluminium, en acier carbone, ou encore en acier inoxydable, intègre un ou plusieurs joints d'étanchéité 8, une gorge 9 d'intégration de quincaillerie, et un système de solidarisation au dormant 2. Le profilé 7b facilite l'évacuation des éventuelles eaux de ruissellement et des eaux de son condensation par sa forme, ses joints et d'éventuels orifices. Le profilé 7b de l'ouvrant 3 peut comprendre un joint d'étanchéité 8 qui est en contact avec la vitre externe 2c du dormant 2.To the left of the fir tree seal 6 of the sash 3 is a profile 7b of the sash 3. The profile 7, made of polyamide material, fiberglass, pultruded profile, PVC, aluminum, carbon steel, or even stainless steel, incorporates one or more seals 8, a groove 9 for integrating hardware, and a system for securing to the frame 2. The profile 7b facilitates the evacuation of any runoff water ment and water from its condensation by its shape, its joints and any orifices. The profile 7b of the opening 3 may include a seal 8 which is in contact with the outer pane 2c of the frame 2.

Le profilé 7b de l'ouvrant 3 comprend une surface transversale d'appui 7b1 qui s'étend le long du premier joint 6 de l'ouvrant 3, entre la vitre interne 3c de l'ouvrant 3 et la vitre externe de l'ouvrant 3, et qui s'étend sur l'épaisseur de la vitre externe 3a de l'ouvrant.The profile 7b of the sash 3 comprises a transverse bearing surface 7b1 which extends along the first seal 6 of the sash 3, between the inner pane 3c of the sash 3 and the outer pane of the sash 3, and which extends over the thickness of the outer pane 3a of the sash.

Ainsi, de droite à gauche de l'ouvrant 3, c'est-à-dire en direction du dormant 2, on trouve l'espaceur 4, le joint en silicone 5, le joint sapin 6, et le profilé 7b de l'ouvrant 3.Thus, from right to left of the sash 3, that is to say in the direction of the frame 2, there is the spacer 4, the silicone seal 5, the fir tree seal 6, and the profile 7b of the sash 3.

La quincaillerie est logée dans les gorges 9 des profilés 7. La quincaillerie, qui fait partie de la menuiserie, est un mécanisme constitué de pièces (compas en X, compas en Y, tringles, goujon, mortaise, crémone, renvoi d'angle, paumelle, paumelle d'angle, etc.) en aluminium, en acier inoxydable, en polyamide, en PVC ou en fibre de verre.The hardware is housed in the grooves 9 of the profiles 7. The hardware, which is part of the carpentry, is a mechanism made up of parts (X compass, Y compass, rods, dowel, mortise, cremone bolt, bevel gear, hinge, corner hinge, etc.) made of aluminium, stainless steel, polyamide, PVC or fiberglass.

La quincaillerie comprend un système 13a de fermeture de l'ouvrant 3 sur le dormant 2, au niveau de la zone de recouvrement 2, ainsi qu'un système 13b permettant à l'ouvrant 3 de se déplacer par rapport au dormant 2, par exemple par rotation de l'ouvrant par rapport au montant de façade 11.The hardware comprises a system 13a for closing the sash 3 on the frame 2, at the level of the overlap zone 2, as well as a system 13b allowing the sash 3 to move relative to the frame 2, for example by rotation of the sash relative to the front upright 11.

L'ouvrant 3 peut avoir différents types de mouvements :

  • par rotation ou translation rotative dite « à la française », à un ou deux vantaux,
  • par rotation ou translation rotative dite « à l'anglaise », à un ou deux vantaux,
  • à projection dite « à l'italienne », intérieure ou extérieure,
  • à projection dite « à soufflet », intérieure ou extérieure,
  • à projection parallèle ou dite « pantographique », intérieure ou extérieure,
  • à l'australienne.
The sash 3 can have different types of movement:
  • by rotation or rotary translation called “French style”, with one or two leaves,
  • by rotation or rotary translation called "English style", with one or two leaves,
  • with so-called "Italian" projection, indoor or outdoor,
  • with so-called "bellows" projection, interior or exterior,
  • with parallel or so-called "pantographic" projection, interior or exterior,
  • Australian style.

Le mécanisme de quincaillerie du dispositif de fenêtre 10 permet la mise en pression des joints des profilés 7a, 7b du dormant 2 et de l'ouvrant 3 afin de permettre une bonne étanchéité à l'eau et à l'air de l'ouvrant en position fermée. Les gorges 9 des profilés 7 du dormant 2 et de l'ouvrant 3 sont des formes ouvertes dans les profils permettant la fixation de la quincaillerie (par vissage, par clameaux, par collage, etc.), ces gorges 9 peuvent être des gorges européennes ou des gorges de gammiste de menuiserie par exemple.The hardware mechanism of the window device 10 allows the pressurization of the joints of the profiles 7a, 7b of the frame 2 and of the opening 3 in order to allow a good water and airtightness of the opening in the closed position. The grooves 9 of the profiles 7 of the frame 2 and of the opening 3 are open shapes in the profiles allowing the fixing of the hardware (by screwing, by clamps, by gluing, etc.), these grooves 9 can be European grooves or carpentry lineman grooves for example.

En outre, il n'y a pas de châssis à l'extérieur du vitrage externe 3a de l'ouvrant 3 et il n'y a pas de châssis à l'intérieur du vitrage interne 3c de l'ouvrant 3.In addition, there is no frame outside the external glazing 3a of the sash 3 and there is no frame inside the internal glazing 3c of the sash 3.

Les figures 8 à 10 illustrent différents modes de fixation des profilés 7 aux vitrages du dormant 2 et de l'ouvrant 3.THE figures 8 to 10 illustrate different methods of fixing the profiles 7 to the glazing of the frame 2 and the opening 3.

Dans un premier mode de réalisation, tel qu'illustré à la figure 8, les profilés 7a, 7b sont collés aux vitrages.In a first embodiment, as illustrated in figure 8 , the profiles 7a, 7b are glued to the glazing.

Dans un deuxième mode de réalisation, chaque profilé 7 est pris en feuillure entre les différentes vitres à bord décalé (figure 9).In a second embodiment, each profile 7 is rebated between the different panes with offset edges ( figure 9 ).

Dans un troisième mode de réalisation, les profilés 7 intègrent des clames 15 venant se loger dans des profils intégrés aux joints 5, 6 (figure 10).In a third embodiment, the profiles 7 integrate clamps 15 which are housed in profiles integrated into the joints 5, 6 ( figure 10 ).

Dans un mode de réalisation ne faisant pas partie de l'invention et illustré à la figure 11, sur laquelle les éléments identiques à ceux des figures 1 à 10 portent les mêmes références, le dormant 2 comprend un double vitrage. Dans cette variante, on peut utiliser les mêmes composants, les mêmes matériaux et les mêmes distances E1 et E2 que dans le cas décrit ci-dessus où le dormant 2 comprend un triple vitrage.In an embodiment not forming part of the invention and illustrated in figure 11 , on which the elements identical to those of the figures 1 to 10 have the same references, frame 2 includes double glazing. In this variant, the same components, the same materials and the same distances E1 and E2 can be used as in the case described above where the frame 2 comprises triple glazing.

Les avantages du dispositif 10 selon l'invention sont :

  • une réduction de la masse menuisée de l'ouvrant,
  • une augmentation de la lumière pénétrant au travers la façade,
  • une liberté de forme : les vitrages ne sont pas uniquement rectangulaires, le dormant peut être en L, en C ou en O,
  • une facilité de nettoyage des vitres qui sont plus recoupées par des menuiseries (les nus intérieurs des vitrages ouvrants et dormants sont alignés),
  • moins d'aluminium, de bois, de PVC ou d'acier sont nécessaires à la réalisation de l'ouvrant (la frappe de l'ouvrant est réalisée directement par le vitrage du dormant),
  • on utilise un nombre réduit de joints dans les systèmes de menuiserie : les joints entre le cadre de l'ouvrant et le vitrage sont supprimés, cela peut permettre une meilleure étanchéité des façades en supprimant un point de fragilité,
  • une bonne isolation thermique car la largeur de menuiserie présentant des déperditions plus importantes que le vitrage est réduite par rapport aux ouvrants classiques, et la menuiserie ne présente pas de relief et limite donc la surface d'échange thermique avec l'intérieur et l'extérieur, autrement dit elle limite l'effet d'ailette thermique des menuiseries.
The advantages of the device 10 according to the invention are:
  • a reduction in the carpentry mass of the sash,
  • an increase in light penetrating through the facade,
  • freedom of shape: the glazing is not only rectangular, the frame can be L, C or O,
  • an ease of cleaning of the windows which are more intersected by joinery (the bare interiors of the opening and fixed glazing are aligned),
  • less aluminium, wood, PVC or steel are needed to make the sash (the sash is struck directly by the frame glazing),
  • a reduced number of seals are used in carpentry systems: the seals between the frame of the opening and the glazing are eliminated, this can allow better sealing of the facades by eliminating a point of fragility,
  • good thermal insulation because the width of the carpentry with greater losses than the glazing is reduced compared to conventional openings, and the carpentry has no relief and therefore limits the heat exchange surface with the interior and the exterior, in other words it limits the thermal fin effect of the carpentry.

La suite de la description est consacrée à un exemple comparatif montrant la bonne isolation thermique du dispositif de fenêtre selon l'invention.The rest of the description is devoted to a comparative example showing the good thermal insulation of the window device according to the invention.
