In order to enable a light construction of the moving frame (14), the inlet conduit (31), connected to an opening (30) on the outer face of the window, passes in the fixed frame (1) of the window. A regulation and obturation flap (40) is mounted on the fixed frame, as well as a puller (44) for the control of said flap. Preferably, the outlet conduit (36) passes also in the fixed frame. The invention may be used in buildings or windows providing for an aeration and a good phonic and thermal insulation.

Description

La présente invention concerne une fenêtre à aération automatique pour un bâtiment, comportant un châssis mobile sur un cadre fixe, trois vitres parallèles montées dans ce châssis, un premier intervalle entre la vitre intermédiaire et la vitre intérieure, un circuit d'aération à chicanes formé par au moins un conduit d'entrée disposé au bas de la fenêtre pour relier l'air extérieur au premier intervalle, par au moins un conduit intermédiaire ménagé dans la partie supérieure du châssis mobile pour relier le premier intervalle au second, et par au moins un conduit de sortie disposé au bas de la fenêtre pour relier le second intervalle à l'air intérieur du bâtiment, au moins un volet de réglage et d'obturation disposé dans ce circuit, et des moyens de commande de ce volet, munis d'un organe de commande sur la face intérieure de la fenêtre.The present invention relates to an automatic ventilation window for a building, comprising a movable frame on a fixed frame, three parallel windows mounted in this frame, a first gap between the intermediate window and the interior window, a baffle ventilation circuit formed. by at least one inlet duct arranged at the bottom of the window to connect the outside air to the first gap, by at least one intermediate duct formed in the upper part of the movable frame to connect the first gap to the second, and by at least an outlet duct arranged at the bottom of the window for connecting the second gap to the interior air of the building, at least one adjustment and obturation shutter disposed in this circuit, and means for controlling this shutter, provided with a control member on the inside of the window.

On connaît déjà par le brevet français n° 2 437 484 une fenêtre de ce genre, dans laquelle les conduits d'entrée et de sortie sont ménagés dans le châssis mobile de la fenêtre. Ce châssis est équipé de clapets agencés pour limiter ou arrêter la circulation d'air entre les vitres, ainsi que d'organes de commande manuelle de ces clapets. Cette fenêtre permet une aération du local dans lequel elle est montée, tout en asurant une excellente isolation phonique. Toutefois, elle présente divers inconvénients au point de vue de sa construction et de son utilisation. En particulier, la partie inférieure du châssis, renfermant les clapets et les organes de commande, est relativement volumineuse, ce qui réduit la surface libre des vitres. En outre, le poids du châssis mobile est plus élevé que celui d'un châssis traditionnel. D'autre part, il est très difficile de résoudre de manière satisfaisante les problèmes d'étanchéité au bas de la vitre extérieure, de sorte que le fonctionnement des clapets ou une bonne durabilité de la fenêtre ne sont pas assurés si l'on n'effectue pas un entretien régulier. Par ailleurs, avec son châssis relativement lourd et volumineux, ce dispositif est malcommode sur une fenêtre du type à guillotine.Already known from French Patent No. 2,437,484 a window of this kind, in which the inlet and outlet conduits are formed in the movable frame of the window. This chassis is fitted with valves arranged to limit or stop the circulation of air between the panes, as well as with manual control members for these valves. This window allows ventilation of the room in which it is mounted, while providing excellent sound insulation. However, it has various drawbacks from the point of view of its construction and use. In particular, the lower part of the frame, containing the valves and the control members, is relatively bulky, which reduces the free surface area of the panes. In addition, the weight of the mobile chassis is higher than that of a traditional chassis. On the other hand, it is very difficult to satisfactorily solve the sealing problems at the bottom of the outer pane, so that the operation of the valves or good durability of the window is not ensured if one does not not perform regular maintenance. Furthermore, with its relatively heavy and voluminous chassis, this device is awkward on a window of the sash type.

On connaît également le brevet français pubilé sous le n° 2 530 721 qui décrit un bloc-fenêtre à deux surfaces vitrées, équipé d'un store à lamelles monté entre les deux surfaces vitrées. Ce bloc-fenêtre comporte des ouvertures ménagées au bas et au haut des dormants intérieur et extérieur et pouvues de clapets permettant leur obturation de manière indépendante.We also know the French patent published under the number 2,530,721 which describes a window unit with two glass surfaces, equipped with a slat blind mounted between the two glass surfaces. This window unit has openings made at the bottom and at the top of the interior and exterior frames and provided with valves allowing them to be closed independently.

Ce type de fenêtre connu qui ne comporte pas trois surfaces vitrées parallèles entre elles, ne réalise pas deux couloirs d'aération définis respectivement par la vitre extérieure et la vitre centrale d'une part, et par la vitre centrale et la vitre intérieure d'autre part. De ce fait la circulation de l'air ne se fait pas selon deux circuits opposés à l'intérieur de la fenêtre, de sorte que l'on a avec cette fenêtre, tous les effets négatifs d'un point de vue thermique des fenêtres pivotantes à axe horizontal, ou des fenêtre doubles classiques.This type of known window which does not have three glazed surfaces parallel to each other, does not produce two ventilation corridors defined respectively by the outer pane and the central pane on the one hand, and by the central pane and the inner pane of somewhere else. Therefore the air circulation does not take place in two opposite circuits inside the window, so that we have with this window, all the negative effects from a thermal point of view of pivoting windows with horizontal axis, or classic double windows.

Par conséquent, la présente invention a pour but de remédier à ces inconvénients, en fournissant une fenêtre dotée d'un circuit d'air qui permet une aération quand la fenêtre est fermée, tout en garantissant une protection efficace contre le bruit. Elle est de construction simple et robuste, nécessite peu d'entretien, et comporte un châssis relativement léger, réalisé avec des matériaux traditionnels.Therefore, the present invention aims to remedy these drawbacks, by providing a window with an air circuit which allows ventilation when the window is closed, while ensuring effective protection against noise. It is simple and robust, requires little maintenance, and has a relatively light chassis, made with traditional materials.

Dans ce but, la fenêtre selon la présente invention est caractérisée en ce que le conduit d'entrée est ménagé au bas de la fenêtre dans le cadre fixe, en ce que le conduit de sortie est ménagée au bas de la fenêtre dans la cadre fixe et/ou dans le châssis mobile, et en ce qu'au moins le conduit d'entrée pourvu d'une ouverture d'entrée localisée à l'extérieur est équipé dudit volet de réglage" et d'obturation, monté sur le cadre fixe ainsi que ses moyens de commande disposés à l'intérieur.For this purpose, the window according to the present invention is characterized in that the inlet duct is provided at the bottom of the window in the fixed frame, in that the outlet duct is provided at the bottom of the window in the fixed frame and / or in the movable frame, and in that at least the inlet duct provided with an inlet opening located outside is equipped with said adjustment and shutter, mounted on the fixed frame as well as its control means arranged inside.

Selon un mode de réalisation préféré, le volet est pivotant autour d'un axe horizontal sur au moins un support solidaire du cadre fixe, et l'axe de pivotement du volet est situé plus haut que l'ouverture à obturer, le volet étant agencé de telle manière par rapport à son axe de pivotement qu'il tend à se refermer par son propre poids.According to a preferred embodiment, the flap is pivotable about a horizontal axis on at least one support integral with the fixed frame, and the pivot axis of the flap is located higher than the opening to be closed, the flap being arranged in such a way with respect to its pivot axis that it tends to close by its own weight.

Lesdits moyens de commande du volet comprennent avantageusement une tirette comportant une tige agencée pour coulisser dans le cadre fixe, une poignée fixée à l'extrémité de cette tirette du côté intérieur de la fenêtre, l'extrémité extérieur de la tige étant en contact avec le volet, et un mécanisme d'encliquetage à crans permettant un blocage de la tirette dans au moins deux positions axiales déterminées.Said shutter control means advantageously comprise a pull tab comprising a rod arranged to slide in the fixed frame, a handle fixed to the end of this pull tab on the inside of the window, the external end of the rod being in contact with the flap, and a detent snap mechanism for locking the zipper in at least two determined axial positions.

La seconde extrémité de la tige et le volet comportent de préférence des moyens de couplage pour entraîner le volet par la tirette dans uns ens et dans l'autre.The second end of the rod and the flap preferably comprise coupling means for driving the flap by the pull tab in one set and in the other.

La tige est de préférence reliée à la poignée par des moyens à ressorts.The rod is preferably connected to the handle by spring means.

Selon un mode de réalisation avantageux, un ventilateur électrique peut être raccordé au circuit d'aération.According to an advantageous embodiment, an electric fan can be connected to the ventilation circuit.

Ce ventilateur peut être monté dans le cadre fixe de la fenêtre.This fan can be mounted in the fixed window frame.

Il peut être disposé en parallèle avec ladite ouverture d'entrée, relié d'une part à une ouverture extérieure équipée d'un organe mobile d'obturation et, d'autre part, au conduit d'entrée, le cadre fixe de la fenêtre étant équipé de moyens de commande de ce ventilateur et de l'organe d'obturation.It can be arranged in parallel with said inlet opening, connected on the one hand to an external opening equipped with a movable shutter member and, on the other hand, to the inlet duct, the fixed frame of the window being equipped with means for controlling this fan and the shutter member.

Selon une variante de réalisation, le ventilateur peut faire partie d'un appareil de climatisation.According to an alternative embodiment, the fan can be part of an air conditioning unit.

Le circuit d'aération peut avantageusement comporter un filtre amovible disposé dans le cadre fixe.The ventilation circuit can advantageously include a removable filter placed in the fixed frame.

Les trois vitres ont de préférence les mêmes dimensions.The three panes preferably have the same dimensions.

Selon un mode de réalisation particulièrement avantageux, le châssis mobile comporte trois éléments qui sont articulés les uns par rapport aux autres, chacun de ces éléments servant de châssis à l'une des vitres.According to a particularly advantageous embodiment, the movable frame comprises three elements which are articulated with respect to each other, each of these elements serving as a frame for one of the panes.

La fenêtre représentée sur la fig. 1 comprend un cadre fixe 1 comportant des profilés métalliques 2 à 9 et des profils d'étanchéité 11, 12 et 13 en matière synthétique ou en caoutchouc, et un châssis mobile 14 monté sur le cadre fixe de manière articulée, par exemple par des gonds (non représentés), de manière à pouvoir pivoter pour l'ouverture de la fenêtre. Le châssis mobile 14 comprend en fait trois éléments de châssis 15, 16 et 17 qui entourent et supportent respectivement trois vitres parallèles, à savoir une vitre extérieure 18, une vitre intermédiaire 19 et une vitre intérieur 20. Les éléments de châssis 15, 16 et 17 sont fixés ensemble le long des côtés de la fenêtre d'une manière connue en soi, par exemple grâce à des gonds le long d'un des côtés, et des vis le long de l'autre pour permettre de les écarter en vue du nettoyage de l'intérieur de la fenêtre. Entre les vitres, on définit un premier intervalle 21 situé entre la vitre extérieure 18 et la vitre intermédiaire 19, et un second intervalle 22 situé entre la vitre intermédiaire 19 et la vitre intérieure 20.The window shown in fig. 1 comprises a fixed frame 1 comprising metal profiles 2 to 9 and sealing profiles 11, 12 and 13 made of synthetic material or rubber, and a movable frame 14 mounted on the fixed frame in an articulated manner, for example by hinges (not shown), so that you can pivot to open the window. The movable frame 14 in fact comprises three frame elements 15, 16 and 17 which respectively surround and support three parallel panes, namely an outer pane 18, an intermediate pane 19 and an inner pane 20. The frame elements 15, 16 and 17 are fixed together along the sides of the window in a manner known per se, for example by means of hinges along one of the sides, and screws along the other to allow them to be separated for the purpose of cleaning the inside of the window. Between the panes, a first interval 21 situated between the outer pane 18 and the intermediate pane 19 is defined, and a second gap 22 located between the intermediate pane 19 and the inner pane 20.

Au-dessus du premier intervalle 21, le châssis mobile comporte une ou plusieurs fentes 23 ménagées entre les éléments de châssis 15 et 16. De même, une ou plusieurs fentes 24 sont ménagées entre les éléments de châssis 16 et 17, au-dessus du second intervalle 22. Les fentes respectives 23 et 24 sont en communication, à l'intérieur du châssis mobile 14, par un conduit intermédiaire 25 situé au-dessus de la vitre intermédiaire 19 et de son élément de châssis 16. En variante, le conduit intermédiaire 25 pourrait aussi être constitué par des fentes traversant la partie supérieure de l'élément de châssis 16. Grâce au conduit intermédiaire 25, l'air renfermé dans le premier intervalle 21 est en communication avec l'air qui se trouve dans le second intervalle 22.Above the first gap 21, the movable chassis has one or more slots 23 formed between the chassis elements 15 and 16. Likewise, one or more slots 24 are formed between the chassis elements 16 and 17, above the second interval 22. The respective slots 23 and 24 are in communication, inside the movable frame 14, by an intermediate conduit 25 situated above the intermediate window 19 and its frame element 16. As a variant, the conduit intermediate 25 could also be constituted by slots passing through the upper part of the chassis element 16. Thanks to the intermediate duct 25, the air contained in the first interval 21 is in communication with the air which is in the second interval 22.

De manière analogue, la partie inférieure du châssis mobile 14 comporte une ou plusieurs fentes 26 ménagées entre les éléments de châssis 15 et 16 au-dessous du premier intervalle 21 et une ou plusieurs fentes 27 ménagées entre les éléments de châssis 16 et 17 au-dessous du second intervalle 22. Quand la fenêtre est fermée, comme le montre la fig. 1, les fentes 26 et 27 ne sont pas en communication en dessous de la vitre intermédiaire 19, car elles sont séparées par l'élément de châssis intermédiaire 16 s'appuyant contre un profil d'étanchéité 12 du cadre fixe.Similarly, the lower part of the movable chassis 14 has one or more slots 26 formed between the chassis elements 15 and 16 below the first gap 21 and one or more slots 27 formed between the chassis elements 16 and 17 below the second interval 22. When the window is closed, as shown in fig. 1, the slots 26 and 27 are not in communication below the intermediate window 19, because they are separated by the intermediate frame element 16 pressing against a sealing profile 12 of the fixed frame.

De préférence, les fentes 23, 24, 26 et 27 sont continues sur toute la largeur de la fenêtre. Toutefois, on peut les fractionner en prévoyant plusieurs fentes consécutivs, séparées par des entretoises qui assurent un appui de l'élément de châssis intermédiaire 16 contre les éléments de châssis 15 et 17 pour accroître la rigidité du châssis mobile.Preferably, the slots 23, 24, 26 and 27 are continuous over the entire width of the window. However, they can be split by providing several consecutive slots, separated by spacers which provide support for the intermediate chassis element 16 against the chassis elements 15 and 17 to increase the rigidity of the movable chassis.

Conformément à l'invention, le cadre fixe 1 comporte, sur sa face extérieure, une ouverture d'entrée 30 qui est reliée au premier intervalle 21 par un conduit d'entrée 31 s'étendant à la fois dans le cadre fixe et, par la fente 26, dans le châssis mobile. Dans l'exemple représente, le conduit d'entrée 31 passe par une ouverture horizontale 32 du cadre fixe, dans laquelle est disposé un filtre amovible 33 représenté schématiquement en traits interrompus et destiné à arrêter les poussières, les insectes, etc.According to the invention, the fixed frame 1 comprises, on its outer face, an inlet opening 30 which is connected to the first gap 21 by an inlet duct 31 extending both in the fixed frame and, by the slot 26 in the movable chassis. In the example shown, the inlet duct 31 passes through a horizontal opening 32 of the fixed frame, in which is disposed a removable filter 33 shown schematically in broken lines and intended to stop dust, insects, etc.

Les ouvertures 30 et 32 s'étendent de préférence sur la plus grande partie de la largeur de la fenêtre, mais elles peuvent aussi être constituées de plusieurs ouvertures juxtaposées.The openings 30 and 32 preferably extend over the greatest part of the width of the window, but they can also consist of several juxtaposed openings.

De manière analogue, la partie inférieure du cadre fixe 1 comporte, du côté intérieur de la fenêtre, une ouverture de sortie 34, une ouverture horizontale 35 et un conduit de sortie 36 qui relie le second intervalle 22 à l'ouverture de sortie 34 en passant par la fente 27. Ainsi, on dispose d'un circuit d'air allant de l'ouverture d'entrée 30 à l'ouverture de sortie 34 par le conduit d'entrée 31, le premier intervalle 21, le conduit intermédiaire 25, le second intervalle 22 et le conduit de sortie 36, circuit que l'air peut parcourir comme l'indique les flèches de la fig. 1, ou dans le sens contraire dans certains cas. Ce circuit comporte un grand nombre de chicanes, notamment par le fait que l'air introduit dans la partie inférieure de la fenêtre est détourné jusqu'à la partie supérieure, puis doit redescendre, ce qui assure une très forte atténuation des bruits extérieurs transmis par l'air vers l'intérieur du bâtiment.Similarly, the lower part of the fixed frame 1 has, on the inside of the window, an outlet opening 34, a horizontal opening 35 and an outlet conduit 36 which connects the second gap 22 to the outlet opening 34 in passing through the slot 27. Thus, there is an air circuit going from the inlet opening 30 to the outlet opening 34 through the inlet duct 31, the first interval 21, the intermediate duct 25 , the second interval 22 and the outlet duct 36, a circuit that air can travel as indicated by the arrows in FIG. 1, or in the opposite direction in some cases. This circuit includes a large number of baffles, in particular by the fact that the air introduced into the lower part of the window is diverted up to the upper part, then must go down again, which ensures a very strong attenuation of the external noises transmitted by the air towards the interior of the building.

Pour obturer partiellement ou totalement l'ouverture d'entrée 30, afin de permettre de régler ou d'interrompre la circulation de l'air, un volet 40 est monté sur la face extérieure du cadre fixe de al fenêtre. Ce volet 40 est constitué par un profilé métallique ou en matière synthétique qui s'étend sur la plus grande partie de la largeur de la fenêtre. Sa face arrière comporte une portion plane agencée pour recouvrir entièrement la ou les ouvertures d'entrée 30 s'étendant le long de la fenêtre. Le long de son bord supérieur, le volet 40 comporte un bourrelet cylindrique 41 qui définit un axe de pivotement horizontal. Ce bourrelet est introduit dans une gorge cylindrique d'un ou plusieurs supports 42 fixés au cadre de la fenêtre. D'autre part, la partie inférieure 43 du volet 40 présente une forme élargie, de telle manière que le centre de gravité du volet se trouve décalé vers l'extérieur par rapport au centre de pivotement, de sorte que le volet 40 tend à se refermer par son propre poids.To partially or completely close the inlet opening 30, in order to allow the air circulation to be regulated or interrupted, a shutter 40 is mounted on the outer face of the fixed frame of the window. This flap 40 is constituted by a metal or plastic profile which extends over the greater part of the width of the window. Its rear face has a flat portion arranged to completely cover the inlet opening or openings 30 extending along the window. Along its upper edge, the flap 40 comprises a cylindrical bead 41 which defines a horizontal pivot axis. This bead is introduced into a cylindrical groove of one or more supports 42 fixed to the window frame. On the other hand, the lower part 43 of the flap 40 has an enlarged shape, so that the center of gravity of the flap is offset towards the outside with respect to the pivot center, so that the flap 40 tends to close by its own weight.

Pour commander la position du volet 40, la fenêtre selon l'invention comporte simplement une tirette 44 qui est montée dans la partie inférieure du cadre fixe 1. Dans l'exemple illustré sur la fig. 1, la tirette 44 comprend un support 45, une douille coulissante 46 munie d'une poignée en forme de bouton 47 du côté intérieur de la fenêtre, et une tige coulissant 48 dont l'extrémité extérieure est en appui contre le volet 40. L'autre extrémité de la tige 48 comporte une tête 49 qui est serrée dans la douille 46 entre deux ressorts 50 et 51 grâce à une vis de réglage 52, afin d'atténuer la transmission à la tirette 44 des chocs qui peuvent être produits par le volet 40 sur la tige 48.To control the position of the flap 40, the window according to the invention simply comprises a pull tab 44 which is mounted in the lower part of the fixed frame 1. In the example illustrated in FIG. 1, the pull tab 44 comprises a support 45, a sliding bush 46 provided with a button-shaped handle 47 on the inside of the window, and a sliding rod 48 whose outer end bears against the flap 40. L 'other end of the rod 48 has a head 49 which is clamped in the sleeve 46 between two springs 50 and 51 by means of an adjustment screw 52, in order to attenuate the transmission to the pull tab 44 of the shocks which can be produced by the flap 40 on the rod 48.

La tirette 44 comporte en outre un mécanisme d'encliquetage à crans permettant un blocage de la tirette dans plusieurs positions axiales déterminées, correspondant à plusieurs positions du volet 40. Ce mécanisme est illustré par les fig. 1 et 2. Le support 45 de la tirette comporte, dans un alésage latéral, un dispositif appelé "vis à bille" constitué de manière connue par une bille 54, un ressort hélicoïdal 55 et une vis 56 assurant une pression du ressort contre la bille. La douille 46, agencée pour coulisser axialement dans le support 45, comporte sur sa périphérie une série de rainures circulaires 57 dans lesquelles peut s'engager la bille 54 pour verrouiller la position axiale de la douille 46. Ainsi, chaque rainure 57 correspond à une position déterminée de la tirette 44 et du volet 40.The pull tab 44 further comprises a detent snap mechanism allowing the pull pull to be locked in several determined axial positions, corresponding to several positions of the flap 40. This mechanism is illustrated in FIGS. 1 and 2. The support 45 of the pull tab comprises, in a lateral bore, a device called "ball screw" constituted in a known manner by a ball 54, a helical spring 55 and a screw 56 ensuring a pressure of the spring against the ball . The sleeve 46, arranged to slide axially in the support 45, has on its periphery a series of circular grooves 57 in which the ball 54 can engage to lock the axial position of the sleeve 46. Thus, each groove 57 corresponds to a determined position of the pull tab 44 and of the flap 40.

Sur la fig. 1, la tirette 44 est représentée en position de fermeture du volet 40. Lorsqu'on déplace la tirette en amenant le bouton 47 dans la position 47a dessinée en traits interrompus, l'extrémité de la tige 48 pousse le volet 40 jusqu'à une position d'ouverture 40a dessinée en traits interrompus, puis elle le maintient dans cette position sous l'effet de la vis à bille engagée dans la rainure 57 correspondante. Le circuit d'air traversant la fenêtre est alors ouvert et l'aération se produit en fonction des conditions régnant à l'extérieur et à l'intérieur du bâtiment. La plupart du temps, l'air est plus chaud à l'intérieur du bâtiment et celui-ci comporte des gaines de ventilation qui favorisent le tirage, de sorte que l'air a tendance à entrer par la fenêtre selon l'invention et à circuler comme l'indiquent les flèches de la fig. 1. Dans une certaine mesure, l'utilisateur peut régler le débit de l'air au moyen du volet 40 en agissant sur la tirette 44.In fig. 1, the zipper 44 is shown in the closed position of the flap 40. When the zipper is moved by bringing the button 47 to the position 47a drawn in broken lines, the end of the rod 48 pushes the flap 40 to a open position 40a drawn in broken lines, then it maintains it in this position under the effect of the ball screw engaged in the corresponding groove 57. The air circuit passing through the window is then opened and ventilation occurs according to the conditions prevailing outside and inside the building. Most of the time, the air is warmer inside the building and the latter has ventilation ducts which promote draft, so that air tends to enter through the window according to the invention and to move as indicated by the arrows in fig. 1. To a certain extent, the user can adjust the air flow by means of the flap 40 by acting on the pull tab 44.

Dans la forme de réalisation décrite ci-dessus, le volet est simplement en appui contre l'extrémité de la tige 48 de la tirette ou contre la face extérieure du cadre, de sorte qu'il peut être soulevé dans certains cas, par exemple par une violente rafale de vent. Un tel mouvement peut provoquer des bruits désagréables ou des courants d'air dans le bâtiment. La fig. 3 illustre une disposition permettant de remédier à cet inconvénient en fraisant, dans la partie postérieure du volet 40, une rainure 60 orientée perpendiculairement à l'axe de pivotement du volet et présentant une section sensiblement cylindrique, plus étroite à la surface du volet qu'en profondeur. A son extrémité inférieure, la rainure 60 comporte un orifice d'introduction 61 dont le diamètre est égal à celui du cylindre s'inscrivant dans la rainure 60. La tige 48 utilisée ce cas est pourvue, à son extrémité, d'un bouton sphérique 62 que l'on introduit par l'orifice d'introduction 61 et qui reste . ensuite prisonnier dans le reste de la rainure 60, si bien que le volet 40 ne peut pivoter ni dans un sens, ni dans l'autre. L'orifice 61 est disposé suffisamment bas pour qu'il ne soit jamais atteint par le bouton sphérique 62, sauf l'on tire la tige 48 vers l'extérieur en comprimant fortement le ressort 51 (fig. 1).In the embodiment described above, the flap is simply in abutment against the end of the rod 48 of the pull tab or against the external face of the frame, so that it can be lifted in certain cases, for example by a violent gust of wind. Such movement can cause unpleasant noises or drafts in the building. Fig. 3 illustrates an arrangement making it possible to remedy this drawback by milling, in the rear part of the flap 40, a groove 60 oriented perpendicular to the pivot axis of the flap and having a substantially cylindrical section, narrower at the surface of the flap than in depth. At its lower end, the groove 60 has an insertion orifice 61 whose diameter is equal to that of the cylinder inscribed in the groove 60. The rod 48 used in this case is provided, at its end, with a spherical button 62 which is introduced through the introduction orifice 61 and which remains. then trapped in the rest of the groove 60, so that the flap 40 can not rotate either in one direction or the other. The orifice 61 is placed low enough that it is never reached by the spherical button 62, except the rod 48 is pulled outwards by strongly compressing the spring 51 (fig. 1).

Par rapport à l'art antérieur mentionné plus haut, la fenêtre représentée sur la fig. 1 présente des avantages notables. Les dimensions et le poids du châssis mobile 14 sont semblables à ceux d'une fenêtre à triple vitre sans circuit d'aération. En outre, son dispositif d'étanchéité est également le même que celui des fenêtres habituelles, donc il ne présente pas de problème particulier. Enfin, les éléments de châssis peuvent être réalisés avec les profilés métalliques habituels, dans lesquels il n'est pas nécessaire d'aménager des conduits transversaux ou de loger des mécanismes.Compared to the prior art mentioned above, the window shown in FIG. 1 has notable advantages. The dimensions and the weight of the movable frame 14 are similar to those of a triple-pane window without a ventilation circuit. In addition, its sealing device is also the same as that of usual windows, so it does not present any particular problem. Finally, the chassis elements can be produced with the usual metal profiles, in which it is not necessary to arrange transverse conduits or to house mechanisms.

Un autre avantage important de la présente invention est le fait de permettre un raccordement facile d'un ventilateur électrique au circuit d'aération, puisque celui-ci traverse nécessairement des parties fixes de la fenêtre. Par example, ce ventilateur peut être disposé dans le bâtiment et être raccordé au conduit de sortie 36 soit par l'ouverture de sortie 34, soit par une autre ouverture disposée à proximité d'un angle de la fenêtre. Un tel ventilateur peut, par exemple, être un élément d'un appareil de climatisation.Another important advantage of the present invention is the fact of allowing easy connection of an electric fan to the ventilation circuit, since the latter necessarily passes through fixed parts of the window. For example, this fan can be placed in the building and be connected to the outlet duct 36 either by the outlet opening 34, or by another opening arranged near a corner of the window. Such a fan can, for example, be an element of an air conditioning unit.

La fig. 4 illustre une disposition avantageuse d'un ventilateur 64 installé dans le cadre fixe de la fenêtre. Cette figure montre schématiquement en coupe horizontale le conduit d'entrée 31 du circuit d'air, l'ouverture d'entrée 30 étant obturée par le volet 40. Le ventilateur 64 est monté dans un compartiment séparé, près d'un angle de le fenêtre, et il est actionné par un moteur électrique 65 qui est également logé à l'intérieur du cadre 1. Du côté de l'aspiration, le ventilateur 64 est raccordé à une ouverture d'aspiration 66 ménagée sur la face extérieure du cadre 1 et équipée d'un volet d'obturation 67 qui peut être de construction similaire à celle du volet 40. Le ventilateur 64 comporte une tubulure de refoulement 68 qui est raccordée directement au conduit d'entrée 31. Enfin, une tirette 69 à deux positions est reliée au volet 67, ainsi qu'à un levier 70 commandant le fonctionnement du moteur 65, de manière à actionner simultanément l'ouverture du volet 67 et la mise en marche du ventilateur 64.Fig. 4 illustrates an advantageous arrangement of a fan 64 installed in the fixed frame of the window. This figure shows schematically in horizontal section the inlet duct 31 of the air circuit, the inlet opening 30 being closed by the flap 40. The fan 64 is mounted in a separate compartment, near an angle of the window, and it is actuated by an electric motor 65 which is also housed inside the frame 1. On the suction side, the fan 64 is connected to a suction opening 66 formed on the outside of the frame 1 and equipped with a shutter 67 which can be of similar construction to that of the shutter 40. The fan 64 comprises a discharge tube 68 which is directly connected to the inlet duct 31. Finally, a pull tab 69 with two positions is connected to the shutter 67, as well as to a lever 70 controlling the operation of the motor 65, so as to simultaneously actuate the opening of the shutter 67 and the starting of the fan 64.

Le dispositif représenté sur la fig. 4 peut fonctionner sans l'aide du ventilateur, comme décrit plus haut. Il suffit pour cela d'ouvrir le volet 40. Si l'on désire produire une aération forcée, on ferme le volet 40 au moyen de la tirette 44 et l'on ouvre le volet 67 au moyen de la tirette 69, ce qui provoque la mise en marche du ventilateur 64. Celui-ci aspire l'air extérieur par l'orifice 66 et il le refoule vers l'intérieur du bâtiment par le circuit d'air traversant la fenêtre. Comme ce cricuit est relativement long et présente plusieurs chicanes, le bruit produit par le ventilateur est étouffé. Les fig. 5 et 6 illustrent deux autres formes de réalisations d'une fenêtre selon l'invention, dans lesquelles le cadre fixe et le châssis mobile sont réalisés en bois.The device shown in fig. 4 can operate without the help of the fan, as described upper. It suffices to open the flap 40. If one wishes to produce forced ventilation, the flap 40 is closed by means of the pull tab 44 and the flap 67 is opened by means of the pull tab 69, which causes the start-up of the fan 64. The latter sucks in the outside air through the orifice 66 and it discharges it towards the inside of the building by the air circuit passing through the window. As this cricuit is relatively long and has several baffles, the noise produced by the fan is muffled. Figs. 5 and 6 illustrate two other embodiments of a window according to the invention, in which the fixed frame and the movable frame are made of wood.

La fenêtre illustrée par la fig. 5 comporte un cadre fixe 71 et un châssis mobile 72 qui porte les trois vitres 18, 19 et 20 disposées comme précédemment. Le châssis 72 est réalisé en deux éléments 73 et 74 qui sont articulés l'un sur l'autre de manière traditionnelle à l'aide de gonds. La vitre intermédiaire 19 est montée entre les deux éléments de châssis 73 et 74 à l'aide d'un cadre auxiliaire 75.The window illustrated in fig. 5 comprises a fixed frame 71 and a movable frame 72 which carries the three panes 18, 19 and 20 arranged as before. The frame 72 is made of two elements 73 and 74 which are hinged to one another in the traditional way using hinges. The intermediate window 19 is mounted between the two frame elements 73 and 74 using an auxiliary frame 75.

Dans son principe, le circuit d'aération traversant cette fenêtre est identique à celui de la fenêtre de la fig. 1. Il comporte notamment un conduit d'entrée 76 et un conduit de sortie 77 qui traversent à la fois le cadre fixe et le châssis mobile dans la partie inférieure de la fenêtre. Le conduit d'entrée 76 est muni d'un filtre amovible 78 et d'un volet de réglage et d'obturation 80 commandé par une tirette 81. Dans la partie supérieure du châssis 72, un conduit intermédiaire 82 relie entre eux les deux intervalles 21 et 22 situés entre les vitres.In principle, the ventilation circuit passing through this window is identical to that of the window in FIG. 1. It comprises in particular an inlet conduit 76 and an outlet conduit 77 which pass through both the fixed frame and the movable frame in the lower part of the window. The inlet duct 76 is provided with a removable filter 78 and an adjustment and shutter 80 controlled by a pull tab 81. In the upper part of the frame 72, an intermediate duct 82 connects the two intervals 21 and 22 located between the panes.

Les conduits 76, 77 et 82 présentent des formes simples et ils peuvent être réalisés facilement par fraisage de fentes longitudinales rectangulaires dans le bois. Selon la largeur du châssis, ces fentes peuvent être continues ou se présenter sous la forme d'une succession de plusieurs fentes, entre lesquelles subsistent des entretoises procurant une rigidité suffisante à la fenêtre. Il convient de remarquer que la construction illus- tree ici est extrêmement simple. De plus, elle permet d'utiliser trois vitres présentant les mêmes dimensions, ce qui est particulièrement intéressant au point de vue du stock chez le fabricant.The conduits 76, 77 and 82 have simple shapes and can be easily made by milling rectangular longitudinal slots in the wood. Depending on the width of the frame, these slots may be continuous or be in the form of a succession of several slots, between which remain spacers providing sufficient rigidity to the window. It should be noted that the illustration construction here is extremely simple. In addition, it allows the use of three panes having the same dimensions, which is particularly advantageous from the point of view of stock at the manufacturer.

Les exemples décrits en référence aux fig. 1 à 5 illustrent également un autre avantage important de la présente invention. Grâce à la disposition verticale des conduits d'entrée et de sortie dans la partie inférieur du châssis mobile et grâce à l'absence d'organes de commande dans ce châssis, ces constructions se prêtent tout à fait à la réalisation d'un circuit d'aération dans une fenêtre du type à guillotine, c'est-à-dire dont le châssis est mobile verticalement par rapport au cadre. Bien entendu, ce dispositif d'aération est aussi utilisable pour une fenêtre dont le châssis coulisse dans le sens horizontal.The examples described with reference to figs. 1 to 5 also illustrate another important advantage of the present invention. Thanks to the vertical arrangement of the inlet and outlet conduits in the lower part of the mobile chassis and thanks to the absence of control members in this chassis, these constructions lend themselves perfectly to the realization of a circuit of ventilation in a sash type window, that is to say one whose frame is movable vertically relative to the frame. Of course, this ventilation device can also be used for a window whose frame slides in the horizontal direction.

La fenêtre représentée sur la fig. 6 comporte un cadre fixe 91 et un châssis mobile 92 qui sont réalisés de manière très semblable aux éléments correspondants de la fenêtre de la fig. 5. La partie supérieure de ces deux fenêtres est identique. Par contre, dans le cas de la fig. 6, la fenêtre comporte un conduit de sortie 93 qui s'étend uniquement dans le châssis mobile 92, tandis que le conduit d'entrée 76 est identique à celui qui a été décrit en référence à la fig. 5. Dans certains cas, cette disposition permet de diminuer la hauteur de la partie inférieure de la fenêtre en profitant du fait que la plus grande épaisseur du châssis mobile 92 se trouve toujours du côté intérieur de la fenêtre, tandis que la plus grande épaisseur du cadre 91 se trouve du côté extérieur.The window shown in fig. 6 comprises a fixed frame 91 and a movable frame 92 which are produced very similar to the corresponding elements of the window in FIG. 5. The upper part of these two windows is identical. On the other hand, in the case of FIG. 6, the window comprises an outlet conduit 93 which extends only in the movable frame 92, while the inlet conduit 76 is identical to that which has been described with reference to FIG. 5. In certain cases, this arrangement makes it possible to reduce the height of the lower part of the window by taking advantage of the fact that the greater thickness of the movable frame 92 is always located on the interior side of the window, while the greater thickness of the frame 91 is on the outside.

La présente invention n'est pas limitée aux formes de réalisations décrites, mais elle s'étend à toute modification ou variante évidente pour l'homme de l'art. En particulier, la forme et la disposition des volets de réglage et d'obturation, ainsi que de leurs organes de commande, peuvent faire l'objet de multiples variantes. Ces volets ne sont pas nécessairement placés sur la face extérieure de la fenêtre; ils peuvent aussi être disposés sur l'autre face ou dans l'un des conduits d'entrée ou de sortie, à l'intérieur du cadre fixe.The present invention is not limited to the embodiments described, but it extends to any modification or variant obvious to those skilled in the art. In particular, the shape and arrangement of the adjustment and shutter flaps, as well as their control members, can be the subject of multiple variants. These shutters are not necessarily placed on the outside of the window; they can also be arranged on the other face or in one of the inlet or outlet conduits, inside the fixed frame.
