Description

La présente invention se rapporte à un ouvrant pour fenêtre de type à ouvrant coulissant, ledit ouvrant comportant un cadre destiné à entourer un vitrage, ledit cadre étant muni de parois périphériques intérieure et extérieure entre une partie desquelles un élément saillant d'un dormant, de type rail, est destiné à pénétrer, ledit panneau coulissant sur un rail par l'intermédiaire d'au moins un chariot de roulement, lesdites parois périphériques délimitant entre elles, au moins sur une partie du pourtour du cadre, un espace libre interne et une ouverture périphérique du cadre, lesdites parois périphériques du cadre comportant à leurs extrémités respectives un joint de type joint brosse, destiné à entrer en contact avec ledit élément saillant du dormant de type rail,The present invention relates to an opening for sliding-type type window, said opening comprising a frame intended to surround a glazing unit, said frame being provided with inner and outer peripheral walls between a part of which a projecting element of a frame, of rail type, is intended to penetrate, said sliding panel on a rail via at least one carriage, said peripheral walls defining between them, at least on a part of the periphery of the frame, an internal free space and a peripheral opening of the frame, said peripheral walls of the frame having at their respective ends a seal of the brush seal type intended to come into contact with said projecting element of the rail type frame,

On connaît ce type d'ouvrant coulissant qui présente un inconvénient majeur de laisser traverser les ondes sonores plus particulièrement au niveau de la jonction entre l'ouvrant et le dormant, notamment entre le ou les rails du dormant et l'ouvrant.This type of sliding leaf is known which has a major disadvantage of allowing the sound waves to pass through more particularly at the junction between the opening and the frame, in particular between the frame rail (s) and the opening frame.

En effet, un ouvrant coulissant est normalement soutenu par un dormant sur un rail sur lequel l'ouvrant roule, ou plus rarement glisse, grâce à des chariots ou patins appropriés disposés dans le profilé inférieur du cadre de l'ouvrant. Afin de cacher ces chariots ou patins, le profilé inférieur dispose de parois tombantes destinées également à atténuer les ondes sonores pouvant traverser la fenêtre à cette jonction, et à participer à une isolation fluidique à cet endroit. Ces parois tombantes intérieure et extérieure portent à leurs extrémités basses respectivement un profilé brosse destiné à constituer une barrière fluidique entre les milieux extérieur et intérieur, et à remplir au moins la fonction de filtre anti-poussière, ces profilés brosse venant porter sur le rail du dormant et glissant contre celui-ci lorsque l'ouvrant se déplace. Cependant, l'atténuation de la transmission sonore à travers cette jonction inférieure, avec de tels dispositifs munis de profilés brosse, est très faible et le bruit provenant de l'extérieur se transmet très bien par la jonction inférieure ouvrant-dormant.Indeed, a sliding leaf is normally supported by a frame on a rail on which the opening rolls, or more rarely slides, thanks to appropriate carriages or pads arranged in the lower section of the frame of the opening. In order to hide these carriages or skids, the lower section has falling walls also intended to attenuate the sound waves that can pass through the window at this junction, and participate in fluid insulation at this location. These inner and outer falling walls carry at their lower ends respectively a brush section designed to constitute a fluid barrier between the outer and inner environments, and to fulfill at least the function of dust filter, these brush sections coming to bear on the rail of sleeping and sliding against it when the opening moves. However, the attenuation of the sound transmission through this lower junction, with such devices provided with brush profiles, is very low and the noise coming from the outside is transmitted very well by the lower opening-dormant junction.

On rencontre le même problème de nuisance sonore à la jonction supérieure de l'ouvrant coulissant avec le dormant, au niveau de laquelle l'ouvrant est généralement maintenu en position verticale et guidé par des patins et/ou des profilés brosse, sur un rail du dormant.The same problem of noise is encountered at the upper junction of the sliding leaf with the frame, at which the leaf is generally held in a vertical position and guided by pads and / or brush sections, on a rail of sleeping.

En outre, sur les côtés verticaux du cadre du dormant, le problème est identique, tout au moins sur le côté de l'ouvrant destiné à venir en contact avec la partie verticale du dormant. En effet, la jonction verticale ouvrant-dormant est généralement réalisée par un profilé de l'ouvrant doté de parois latérales intérieure et extérieure portant à leurs extrémités respectivement un profilé brosse destiné à constituer une barrière fluidique entre les milieux extérieur et intérieur, de part et d'autre d'un rail du dormant pénétrant plus ou moins profondément entre ces parois latérales, et entre les profilés brosse lorsque l'ouvrant est en position de fermeture sur la dormant.In addition, on the vertical sides of the frame of the frame, the problem is identical, at least on the side of the opening intended to come into contact with the vertical part of the frame. Indeed, the vertical opening-dormant junction is generally performed by a section of the opening having inner and outer side walls carrying at their ends respectively a brush section intended to constitute a fluid barrier between the outer and inner environments, on the one hand and else a rail of the frame penetrating more or less deeply between these side walls, and between the profiles brush when the opening is in the closed position on the frame.

Ainsi, le cadre d'un ouvrant coulissant de l'art antérieur est entouré de parois périphériques intérieure et extérieure, au moins sur trois de ses côtés, entre une partie desquelles un élément saillant d'un dormant, de type rail, est destiné à pénétrer.Thus, the frame of a sliding leaf of the prior art is surrounded by walls inner and outer peripheries, at least on three of its sides, between a part of which a projecting element of a frame, of type rail, is intended to penetrate.

De telles jonctions présentent l'inconvénient de laisser passer facilement les ondes sonores, et également de constituer des points faibles en matière d'isolation thermique et fluidique.Such junctions have the disadvantage of allowing the sound waves to pass easily, and also of constituting weak points in terms of thermal and fluidic insulation.

On connaît par exemple le document US 3,018,525 qui se rapporte à un élément de garniture d'encadrement à fonction de guidage, de calfeutrage, ou de bourrelet étanche, réalisé en matière plastique, qui peut être associé à un dormant ou un ouvrant de fenêtre, notamment fenêtre coulissante. L'élément de garniture se présente sous la forme d'un joint courant profilé de section transversale en forme de canal dont les extrémités se terminent par des lèvres élastiques qui viennent prendre appui sur le rail de guidage de l'ouvrant coulissant. L'élément de garniture est destiné à empêcher un contact entre le cadre de l'ouvrant et le dormant, et à empêcher une entrée d'air, d'humidité, et d'autres matières étrangères dans l'espace compris entre l'ouvrant et le rail. L'élément de garniture assume une fonction de guide de l'ouvrant coulissant sur le rail.For example, the document is known US 3,018,525 which relates to a framing member with guide function, caulking, or waterproof bead, made of plastic, which can be associated with a frame or a window sash, including sliding window. The packing element is in the form of a profiled streamlined joint of cross section in the form of a channel, the ends of which terminate in resilient lips which bear against the guide rail of the sliding leaf. The packing element is intended to prevent contact between the sash frame and the frame, and to prevent entry of air, moisture, and other foreign matter into the space between the sash and the rail. The packing element assumes a sliding guide function on the rail.

On connaît en outre le document US 2,747,240 qui se rapporte à un joint de guidage et calfeutrage pour coulissant qui adopte la forme d'un profilé en U dont l'intérieur est revêtu d'un matériau d'étanchéité et qui chevauche un rail du dormant. Le matériau d'étanchéité peut être du feutre. L'ouvrant se déplace sur le dormant au moyen de roulette dont le chemin de roulement présente une descente en position de fermeture de la fenêtre permettant au joint de guidage et calfeutrage de se placer au plus près de la surface supérieure du rail 21 du dormant. La fonction du joint de guidage et calfeutrage est d'assurer une meilleure étanchéité à l'eau et à l'air.In addition, the document is known US 2,747,240 which refers to a sliding guide and caulking gasket which is in the form of a U-shaped channel, the inside of which is coated with a sealing material and which overlaps a frame rail. The sealing material may be felt. The opening moves on the frame by means of a wheel whose rolling path has a descent in the closed position of the window allowing the guide and caulking seal to be placed closer to the upper surface of the rail 21 of the frame. The function of the guide and caulking joint is to ensure better water and air tightness.

On connaît en outre le document CH 390 511 qui se rapporte à une porte ou fenêtre coulissante destinée à rouler sur un rail présentant des épaulements latéraux coopérant chacun avec une baguette d'étanchéité du cadre de vantail, réalisée en matériau élastique de type caoutchouc.

Plus précisément, l'invention se rapporte à un ouvrant pour fenêtre de type à ouvrant coulissant, comportant un cadre destiné à entourer un panneau, de type panneau vitré ou analogue, ledit cadre étant muni de parois périphériques intérieure et extérieure entre une partie desquelles un élément saillant d'un dormant, de type rail, est destiné à pénétrer,

  • ledit panneau coulissant sur un rail par l'intermédiaire d'au moins un chariot de roulement,
  • lesdites parois périphériques délimitant entre elles, au moins sur une partie du pourtour du cadre, un espace libre interne et une ouverture périphérique du cadre,
  • lesdites parois périphériques du cadre comportant à leurs extrémités respectives un joint de type joint brosse, destiné à entrer en contact avec ledit élément saillant du dormant de type rail,
caractérisé en ce que ledit ouvrant comprend en outre :
  • des moyens de filtre acoustique pour réduire la transmission d'ondes sonores à travers la fenêtre au niveau de la jonction ouvrant-dormant,
  • lesdits moyens de filtre acoustique étant aptes à être disposés dans ledit espace libre interne,
  • lesdits moyens de filtre acoustique comportant un premier voile apte à obturer au moins en partie l'ouverture périphérique du cadre, ledit premier voile comportant deux ailes souples définissant une fente centrale destinée à coopérer avec ledit élément saillant du dormant en vue d'obturer l'ouverture périphérique du cadre.
More specifically, the invention relates to a sash-type opening window, comprising a frame intended to surround a panel, of glass-panel type or the like, said frame being provided with inner and outer peripheral walls between a part of which a protruding element of a frame, of rail type, is intended to penetrate,
  • said sliding panel on a rail via at least one carriage,
  • said peripheral walls defining between them, at least on part of the perimeter of the frame, an internal free space and a peripheral opening of the frame,
  • said peripheral walls of the frame having at their respective ends a seal of the brush seal type intended to come into contact with said projecting element of the rail type frame,
characterized in that said opening further comprises:
  • acoustic filter means for reducing the transmission of sound waves through the window at the sash-opening junction,
  • said acoustic filter means being able to be arranged in said internal free space,
  • said acoustic filter means comprising a first web capable of closing at least part of the circumferential opening of the frame, said first sail comprising two flexible wings defining a central slot intended to cooperate with said projecting element of the frame to close the frame; peripheral opening of the frame.

L'obturation de l'ouverture périphérique du cadre de l'ouvrant avec des moyens de filtre acoustique permet d'obtenir une bonne isolation acoustique dans cette zone jonction de la fenêtre, en gênant, voire en empêchant, grâce au voile, l'entrée des ondes sonores dans l'espace libre interne. L'ouverture périphérique du cadre est dite obturée au moins en partie en ce que la partie de l'ouverture qui ne serait pas obturée par les moyens de filtre est destinée à être obturée par l'élément saillant du dormant, de type rail, coopérant avec les moyens de filtre lorsque le cadre de l'ouvrant est en position de fermeture contre les profilés correspondant du dormant en vue de fermer totalement l'ouverture périphérique du cadre de l'ouvrant. Ainsi, lorsque l'ouvrant n'est pas en position de fermeture sur le dormant, le voile peut laisser apparaître une ouverture centrale donnant accès dans l'espace interne et qui est obturée lorsque l'ouvrant est placé en position de fermeture. Le joint brosse connu de manière classique vient renforcer la barrière établie dans la jonction ouvrant-dormant, et en outre protéger les moyens de filtre acoustique, notamment le premier voile qui est en principe le plus fin en raison de sa flexibilité nécessaire, et du faible coefficient de frottement que doit opposer l'ouvrant lors de son déplacement sur le dormant. La combinaison du joint brosse et des moyens de filtre acoustique tels que définis permet d'obtenir une excellente isolation acoustique dans cette zone de jonction de la fenêtre.Closing the peripheral opening of the frame of the opening with acoustic filter means provides good sound insulation in this area junction of the window, hindering or even preventing, through the veil, the entrance sound waves in the internal free space. The peripheral opening of the frame is said to be closed at least partly in that the portion of the opening which would not be closed by the filter means is intended to be closed off by the projecting element of the frame, of the type rail, cooperating with the filter means when the frame of the opening is in the closed position against the corresponding profiles of the frame in order to completely close the peripheral opening of the frame of the opening. Thus, when the leaf is not in the closed position on the frame, the veil can reveal a central opening giving access to the internal space and which is closed when the leaf is placed in the closed position. The conventionally known brush seal reinforces the barrier established in the sash-opening junction, and furthermore protects the acoustic filter means, especially the first veil which is in principle the thinnest because of its necessary flexibility, and the weak one. coefficient of friction that must oppose the opening during its movement on the frame. The combination of the brush seal and the acoustic filter means as defined makes it possible to obtain excellent acoustic insulation in this junction area of the window.

La fente centrale des moyens de filtre acoustique, combinée aux ailes souples du voile, permet la pénétration de l'élément saillant du dormant, généralement le rail, plus ou moins profondément à l'intérieur de celle-ci, tout en assurant le contact entre le voile et le rail en vue d'obturer l'ouverture périphérique.The central slot of the acoustic filter means, combined with the flexible wings of the veil, allows the penetration of the projecting element of the frame, generally the rail, more or less deeply inside thereof, while ensuring the contact between the sail and rail to close the peripheral opening.

Selon une caractéristique avantageuse, lesdits moyens de filtre acoustique comportent en outre au moins un deuxième voile apte à venir en contact avec lesdites parois périphériques, et lié au dit premier voile.According to an advantageous characteristic, said acoustic filter means further comprise at least one second web adapted to come into contact with said peripheral walls, and connected to said first web.

Cette caractéristique permet de couvrir les parois périphériques du cadre de l'ouvrant à l'intérieur de l'espace espace libre interne afin de gêner, voire d'empêcher, la répercussion des ondes sonores sur ces parois, et ainsi la transmission des ondes sonores à travers la jonction ouvrant-dormant via ledit espace libre interne.This characteristic makes it possible to cover the peripheral walls of the frame of the opening inside the internal free space space in order to hinder or even prevent the repercussion of the sound waves on these walls, and thus the transmission of the sound waves. through the opening-dormant junction via said internal free space.

Selon une caractéristique avantageuse, lesdits moyens de filtre acoustique comportent en outre un troisième voile apte à établir une continuité du deuxième voile entre lesdites parois périphériques.According to an advantageous characteristic, said acoustic filter means further comprise a third web adapted to establish a continuity of the second web between said peripheral walls.

Cette caractéristique contribue à gêner, voire à empêcher, la répercussion des ondes sonores sur les parois du cadre de l'ouvrant délimitant l'espace libre interne, et permet de simplifier la fabrication des moyens de filtre, par exemple sous la forme d'un profilé.This feature contributes to hindering, or even preventing, the repercussion of the sound waves on the walls of the frame of the opening defining the internal free space, and makes it possible to simplify the manufacture of the filter means, for example in the form of a profile.

Selon une caractéristique avantageuse, lesdits moyens de filtre acoustique adoptent une forme appropriée au dit espace libre interne, et comportent à cet effet une section transversale apte à s'emboîter dans le cadre en sorte de couvrir l'intérieur desdites parois périphériques.According to an advantageous characteristic, said acoustic filter means adopt a shape appropriate to said internal free space, and comprise for this purpose a cross section adapted to fit into the frame so as to cover the inside of said peripheral walls.

Cette caractéristique permet une optimisation de la couverture des parois délimitant l'espace libre interne, en vue de gêner, voire d'empêcher, la répercussion des ondes sonores sur toute paroi délimitant cet espace et d'améliorer ainsi l'isolation acoustique dans la zone de la jonction ouvrant-dormant, et permet de simplifier le montage des moyens de filtre acoustique, par exemple par un assemblage par simple emboîtement de ces derniers entre les parois périphériques du cadre de l'ouvrant.This characteristic makes it possible to optimize the coverage of the walls delimiting the internal free space, with a view to hindering, or even preventing, the repercussion of the sound waves on any wall delimiting this space and thus to improve the acoustic insulation in the zone. of the opening-dormant junction, and simplifies the mounting of the acoustic filter means, for example by a simple assembly interlocking these between the peripheral walls of the frame of the opening.

Selon une caractéristique avantageuse, lesdits moyens de filtre acoustique comportent une section transversale en forme générale de U, ledit premier voile comportant deux ailes souples rattachées respectivement aux extrémités du U et dirigées l'une vers l'autre, en sorte de former une enceinte à l'intérieur des moyens de filtre acoustique, ladite enceinte étant apte à être close avec ou sans la coopération dudit élément saillant du dormant.According to an advantageous characteristic, said acoustic filter means comprise a generally U-shaped cross-section, said first veil comprising two flexible wings attached respectively to the ends of the U and directed toward each other, so as to form an enclosure for the interior of the acoustic filter means, said enclosure being able to be closed with or without the cooperation of said projecting element of the frame.

Une telle caractéristique confère aux moyens de filtre acoustique une forme parfaitement adaptée pour la fabrication en profilé creux, apte à un assemblage aisé dans le cadre de l'ouvrant par pression grâce à une déformation aisée des parois des moyens de filtre, tout en assurant une couverture des parois délimitant l'espace et une obturation de l'ouverture périphérique du cadre. L'enceinte close à l'intérieur des moyens de filtre permet le logement des chariots de roulement en ce qui concerne la partie inférieure du cadre de l'ouvrant, tout en isolant cette enceinte de l'extérieur.Such a characteristic confers on the acoustic filter means a form perfectly adapted for the manufacture of hollow profile, suitable for easy assembly in the frame of the opening by pressure thanks to easy deformation of the walls of the filter means, while ensuring a cover of the walls delimiting the space and a closure of the peripheral opening of the frame. The enclosure closed inside the filter means allows the housing of the trolleys with respect to the lower part of the frame of the opening, while isolating the enclosure from the outside.

Selon une caractéristique avantageuse, ledit premier voile comporte deux ailes flexibles dont la section longitudinale diminue d'épaisseur en s'étendant vers l'extrémité des ailes, respectivement.According to an advantageous characteristic, said first sail comprises two flexible wings whose longitudinal section decreases in thickness extending towards the end of the wings, respectively.

Une telle caractéristique permet d'améliorer la flexibilité des moyens de filtre dans une zone spécifique d'extrémité des ailes dans laquelle ces dernières sont destinées à entrer en contact avec le rail du dormant, et donc à se déformer en vue de laisser le passage dudit rail tout en restant en contact avec celui-ci au repos tout en permettant le frottement de l'extrémité des ailes sur le rail lors d'un coulissement de l'ouvrant sur le rail.Such a feature makes it possible to improve the flexibility of the filter means in a specific end zone of the wings in which the latter are intended to come into contact with the rail of the frame, and thus to deform in order to allow the passage of said rail while remaining in contact with it at rest while allowing the friction of the end of the wings on the rail during a sliding of the opening on the rail.

Selon une caractéristique avantageuse, ledit premier voile possède une épaisseur différente de celle desdits deuxième ou troisième voiles.According to an advantageous characteristic, said first sail has a thickness different from that of said second or third webs.

Une telle caractéristique permet d'optimiser l'espace libre interne, les deuxième et troisième voiles étant normalement destinés à être plus épais que le premier, car devant rester fixes une fois montés dans le cadre de l'ouvrant. L'épaisseur des deuxième et troisième voiles est avantageusement maximale avec des limites déterminées en fonction des dimensions nécessaires de l'enceinte à l'intérieur des moyens de filtres en vue du logement des chariots de roulement ou analogue.Such a characteristic makes it possible to optimize the internal free space, the second and third sails being normally intended to be thicker than the first, because they must remain fixed once mounted in the frame of the opening. The thickness of the second and third webs is advantageously maximum with limits determined according to the necessary dimensions of the chamber inside the filter means for housing rolling carriages or the like.

Selon une caractéristique avantageuse, lesdits premier, deuxième, ou troisième voiles sont des voiles continus, respectivement, sur la longueur d'au moins un côté du cadre.According to an advantageous characteristic, said first, second or third webs are continuous webs, respectively, along the length of at least one side of the frame.

Cette caractéristique permet une fabrication aisée des moyens de filtre acoustique, à la manière d'un joint de vitrage par exemple, par extrusion. En outre, la continuité des voiles permet une optimisation de l'isolation acoustique.This feature allows easy manufacture of acoustic filter means, in the manner of a glazing gasket for example, by extrusion. In addition, the continuity of the sails allows an optimization of the acoustic insulation.

Selon une caractéristique avantageuse, ledit cadre comporte des profilés à rupture de pont thermique, et lesdits moyens de filtre acoustique sont réalisés dans un matériau apte à assurer une rupture de pont thermique entre les parois périphériques intérieure et extérieure du cadre.According to an advantageous characteristic, said frame comprises thermal break profiles, and said acoustic filter means are made of a material capable of providing a thermal break between the inner and outer peripheral walls of the frame.

Selon une caractéristique avantageuse, lesdits moyens de filtre acoustique comprennent un matériau de type caoutchouc ou analogue.According to an advantageous characteristic, said acoustic filter means comprise a material of rubber type or the like.

D'autres caractéristiques et avantages apparaîtront à la lecture qui suit d'un exemple de mode de réalisation d'un ouvrant selon l'invention, accompagnée des dessins annexés, exemple donné à titre illustratif non limitatif.Other features and advantages will appear on reading the following of an exemplary embodiment of an opening according to the invention, accompanied by the accompanying drawings, an example given by way of nonlimiting illustration.

La figure 1 représente une vue en coupe verticale partielle d'un exemple de mode de réalisation d'un ouvrant selon l'invention pour fenêtre de type à ouvrant coulissant.The figure 1 is a partial vertical sectional view of an exemplary embodiment of an opening according to the invention for sliding sash type window.

La figure 2 représente une vue en coupe horizontale partielle de l'exemple de mode de réalisation de l'ouvrant de la figure 1.The figure 2 is a partial horizontal sectional view of the exemplary embodiment of the opening of the figure 1 .

L'ouvrant 1 pour fenêtre de type à ouvrant coulissant, représenté sur la figure 1 comporte un cadre 2 destiné à entourer un panneau 3, de type panneau vitré ou analogue, dans l'exemple un double vitrage, le cadre 2 étant muni de parois périphériques intérieure 4 et extérieure 5 entre une partie desquelles un élément saillant 6 d'un dormant 7, de type rail, est destiné à pénétrer, les parois périphériques 4, 5 délimitant entre elles, au moins sur une partie du pourtour du cadre, c'est à dire sur trois côtés au moins du cadre 2 dans le cas d'espèce, un espace 8 libre interne et une ouverture 11 périphérique du cadre. Les parois périphériques 4, 5 du cadre 2 comportent à leurs extrémités respectives un joint 17 de type joint brosse, destiné à entrer en contact avec l'élément saillant 6 du dormant 7 de type rail.The opening 1 for sliding shutter type window, shown in the figure 1 comprises a frame 2 intended to surround a panel 3, of the glass-panel type or the like, in the example a double glazing, the frame 2 being provided with internal peripheral walls 4 and outer 5 between a part of which a projecting element 6 of a Sleeper 7, of rail type, is intended to penetrate, the peripheral walls 4, 5 defining between them, at least on a part of the periphery of the frame, that is to say on at least three sides of the frame 2 in the case of species, an internal free space 8 and a peripheral opening 11 of the frame. The peripheral walls 4, 5 of the frame 2 comprise at their respective ends a seal 17 of the brush seal type intended to come into contact with the projecting element 6 of the frame-type frame 7.

L'ouvrant 1 comprend en outre :

  • des moyens de filtre acoustique 9 pour réduire la transmission d'ondes sonores à travers la fenêtre au niveau de la jonction ouvrant-dormant,
  • lesdits moyens de filtre acoustique 9 étant aptes à être disposés dans ledit espace 8 libre interne,
  • lesdits moyens de filtre acoustique 9 comportant un premier voile 10 apte à obturer au moins en partie l'ouverture 11 périphérique du cadre.
The opening 1 further comprises:
  • acoustic filter means 9 for reducing the transmission of sound waves through the window at the opening-dormant junction,
  • said acoustic filter means 9 being able to be arranged in said internal free space 8,
  • said acoustic filter means 9 comprising a first web 10 adapted to close at least part of the peripheral opening 11 of the frame.

Le panneau 3 coulissant est apte à rouler sur le rail par l'intermédiaire de deux chariots de roulement (non représentés), dont le montage sera détaillé plus loin en relation avec les moyens de filtre acoustique 9. La présence d'au moins un chariot de roulement dans l'espace 8 libre interne impose la nécessité d'un espace 8 important afin de le ou les loger, notamment en hauteur, dans lequel les ondes sonores se propagent et se répercutent aisément.The sliding panel 3 is able to roll on the rail by means of two trolleys (not shown), whose assembly will be detailed later in connection with the acoustic filter means 9. The presence of at least one trolley rolling in the internal free space 8 imposes the need for a large space 8 in order to house them, especially in height, in which the sound waves propagate and reverberate easily.

Les figures 1 et 2 représentent un exemple d'ensemble ouvrant et dormant pour fenêtre coulissante, de type conventionnel, à l'exception des moyens de filtre acoustique selon l'invention. Sur la figure 1, les chariots de roulement qui pourront être tout chariot de type connu, n'ont pas été représentés afin de simplifier la figure et de mettre mieux en évidence les moyens de filtre acoustique 9. Leur montage sera expliqué plus loin. En ce qui concerne les structures générales de l'ouvrant et du dormant, celles-ci ne seront donc pas plus décrites ici, à l'exception des caractéristiques coopérant avec les moyens de filtration acoustique en vue d'une meilleure compréhension de l'invention.The figures 1 and 2 represent an example of an assembly and sliding frame for sliding window of conventional type, with the exception of the acoustic filter means according to the invention. On the figure 1 , trolleys that can be any trolley of known type, have not been shown to simplify the figure and to better highlight the acoustic filter means 9. Their assembly will be explained later. With regard to the general structures of the opening and the frame, they will therefore not be described here any more, with the exception of the characteristics cooperating with the acoustic filtration means for a better understanding of the invention.

On remarque toutefois que le cadre 2 de l'ouvrant comporte des profilés à rupture de pont thermique, et que l'espace 8 libre interne est de forme sensiblement rectangulaire dans le profilé horizontal 18 inférieur comme dans le profilé vertical 19 destiné à entrer en contact avec le dormant 7 en vue de la fermeture de la fenêtre.Note however that the frame 2 of the opening comprises thermal break profiles, and the internal free space 8 is of substantially rectangular shape in the lower horizontal section 18 as in the vertical section 19 intended to come into contact with the frame 7 to close the window.

Le dormant 3 comporte sur les quatre côtés, de manière conventionnelle un élément saillant 6 de type rail, qui est destiné à pénétrer plus ou moins profondément entre les parois périphériques intérieure 4 et extérieure 5 de trois des quatre côtés du cadre 2 de l'ouvrant 1, à savoir le côté inférieur (figure 1), supérieur (non représenté), et vertical côté dormant (figure 2).The frame 3 comprises on all four sides, in a conventional manner a projecting element 6 of the rail type, which is intended to penetrate more or less deeply between the inner peripheral walls 4 and outer 5 of three of the four sides of the frame 2 of the opening 1, namely the lower side ( figure 1 ), upper (not shown), and vertical standing side ( figure 2 ).

L'espace interne 8 délimité par les parois périphériques intérieure 4 et extérieure 5 est obturé vers le centre du cadre, par opposition à la périphérie de celui-ci, par un fond 20 du profilé 18 ou 19, dans l'exemple représenté constitué par des nervures des profilés intérieur et extérieur et une barre 21 de liaison à rupture de pont thermique. Il est à noter que les éléments fonctionnellement équivalents portent la même référence numérique sur les côtés horizontaux et verticaux représentés de l'ouvrant, sauf exceptions identifiées. L'espace interne 8 libre est de dimension différente sur les côtés vertical et horizontal, comme représenté sur les figures, essentiellement en raison du fait que l'espace du côté inférieur du cadre doit permettre le logement des chariots de roulement : il est donc plus grand, plus particulièrement plus profond, que l'espace du côté vertical représenté du cadre qui lui ne doit permettre que la pénétration plus ou moins profonde de la saillie du dormant en vue d'établir sur ce côté vertical, une liaison mécanique de l'ouvrant avec le dormant visant notamment à rigidifier la fenêtre et à établir une barrière isolant le milieu extérieur de l'intérieur.The internal space 8 delimited by the inner peripheral walls 4 and outer 5 is closed towards the center of the frame, as opposed to the periphery thereof, by a bottom 20 of the profile 18 or 19, in the example represented by ribs of the inner and outer sections and a connecting bar 21 with a thermal break. It should be noted that the functionally equivalent elements carry the same numerical reference on the horizontal and vertical sides represented of the opening, except for identified exceptions. The internal space 8 free is of different size on the vertical and horizontal sides, as shown in the figures, essentially because the space on the underside of the frame must allow the housing of the trolleys: it is therefore more large, more particularly deeper, than the space of the vertical side of the frame which must allow only the penetration more or less deep the projection of the frame to establish on this vertical side, a mechanical connection of the opening with the frame aimed in particular to stiffen the window and to establish an insulating barrier the outside environment of the interior.

Le premier voile 10 des moyens d'isolation acoustique 9 comporte avantageusement deux ailes 15, 16 souples définissant une fente centrale destinée à coopérer avec l'élément saillant 6 du dormant 7 en vue d'obturer l'ouverture 11 périphérique du cadre.The first web 10 acoustic insulation means 9 advantageously comprises two flexible wings 15, 16 defining a central slot intended to cooperate with the projecting element 6 of the frame 7 in order to close the peripheral opening 11 of the frame.

Les moyens de filtre acoustique 9 comportent en outre avantageusement au moins un deuxième voile 12 apte à venir en contact avec les parois périphériques 4, 5, et lié au premier voile 10, et un troisième voile 13 apte à établir une continuité du deuxième voile 12 entre les parois périphériques 4, 5, comme cela sera expliqué plus loin. De manière avantageuse, les moyens de filtre acoustique 9 adoptent une forme appropriée à l'espace 8 libre interne, et comportent à cet effet une section transversale apte à s'emboîter dans le cadre 2 en sorte de couvrir l'intérieur des parois périphériques 4,5.The acoustic filter means 9 further advantageously comprise at least one second web 12 adapted to come into contact with the peripheral walls 4, 5, and connected to the first web 10, and a third web 13 capable of establishing a continuity of the second web 12 between the peripheral walls 4, 5, as will be explained later. Advantageously, the acoustic filter means 9 adopt a shape appropriate to the internal free space 8, and comprise for this purpose a cross section adapted to fit into the frame 2 so as to cover the inside of the peripheral walls 4 5.

Plus particulièrement, les moyens de filtre acoustique 9 comportent une section transversale en forme générale de U, les deux ailes 15, 16 souples du premier voile 10 étant rattachées respectivement aux extrémités du U et dirigées l'une vers l'autre, en sorte de former une enceinte 14 à l'intérieur des moyens de filtre acoustique 9, l'enceinte 14 étant apte à être close avec ou sans la coopération de l'élément saillant 6 du dormant 7. Ainsi, le deuxième voile 12 est constitué des deux parties verticales du U et le troisième voile de la partie horizontale inférieure du U, comme représenté sur les figures, le U adoptant dans l'exemple représenté des angles droits à la jonction des parties verticales et horizontale inférieure afin d'épouser avantageusement au mieux les parois internes du cadre 2 délimitant l'espace interne 8. Dans un souci de simplification de fabrication des moyens d'isolation acoustique 9, et également dans un souci de standardisation de ces derniers, les deuxième 12 et troisième 13 voiles peuvent être respectivement constitué d'une paroi plane en sorte que celle-ci ne suive pas parfaitement la forme des parois internes du cadre délimitant l'espace interne 8 libre, comme cela est le cas pour le fond 20 tel que représenté sur les figures.More particularly, the acoustic filter means 9 comprise a generally U-shaped cross-section, the two flexible wings 15, 16 of the first web 10 being respectively attached to the ends of the U and directed toward each other, so as to forming an enclosure 14 inside the acoustic filter means 9, the enclosure 14 being able to be closed with or without the cooperation of the projecting element 6 of the frame 7. Thus, the second web 12 consists of the two vertical parts of the U and the third web of the lower horizontal part of the U, as shown in the figures, the U adopting in the example shown at right angles to the junction vertical portions and lower horizontal to advantageously marry better the internal walls of the frame 2 defining the internal space 8. For the sake of simplification of manufacturing of sound insulation means 9, and also for the sake of standardization of these last, the second 12 and third 13 sails may respectively consist of a flat wall so that it does not follow perfectly the shape of the inner walls of the frame defining the free internal space 8, as is the case for the bottom 20 as shown in the figures.

Comme représenté sur les figures 1 et 2, les premier 10, deuxième 12, et troisième 13 voiles sont avantageusement des voiles continus, respectivement, sur la longueur d'au moins un côté du cadre 2, permettant d'envisager leur fabrication sous la forme d'un profilé unique, par exemple extrudé en matériau de type caoutchouc ou analogue, éventuellement en bimatériau, afin que les moyens de filtre acoustique 9 soient aptes à assurer une rupture de pont thermique entre les parois périphériques intérieure 4 et extérieure 5 du cadre 2. Les moyens de filtre acoustique 9 peuvent être de dimensions différentes pour le côté vertical et les côtés horizontaux inférieur et supérieur du cadre 2 de l'ouvrant 1, en fonction des besoins, c'est à dire des dimensions des profilés des ouvrants, tout en adoptant avantageusement la même forme simple de section transversale, comme représenté sur les figures.As shown on figures 1 and 2 , the first 10, second 12, and third 13 webs are preferably continuous webs, respectively, along the length of at least one side of the frame 2, to consider their manufacture in the form of a single profile, for example extruded in rubber-like material or the like, possibly in bimaterial, so that the acoustic filter means 9 are able to provide a thermal break between the inner peripheral walls 4 and outer 5 of the frame 2. The acoustic filter means 9 can be of different dimensions for the vertical side and the lower and upper horizontal sides of the frame 2 of the opening 1, as needed, ie the dimensions of the profiles of the opening, while advantageously adopting the same simple form of cross-section, as shown in the figures.

De manière avantageuse, le premier voile 10 comporte deux ailes 15, 16 flexibles dont les sections longitudinales respectives diminuent d'épaisseur en s'étendant vers l'extrémité de l'aile, dans le but de constituer une barrière flexible dont la flexibilité est de plus en plus grande lorsqu'on se rapproche de l'extrémité des ailes, cette partie d'extrémité des ailes étant destinée à se déformer sous l'effet de la pénétration de l'élément saillant 6 du dormant 7, en vue d'assurer le contact avec celui-ci. Il est à noter que sur les figures, les ailes 15 et 16 ont été représentées non déformées et superposées à l'élément saillant 6, dans l'exemple adoptant la forme d'un rail dont la partie supérieure est arrondie, alors que l'ouvrant 1 est en position de fermeture sur le dormant 7, afin de visualiser un exemple d'interception de ces deux éléments. Ainsi, lorsque l'ouvrant est en position appropriée sur le dormant, l'extrémité des ailes 15 et 16 se déforme pour épouser sensiblement et avantageusement la forme arrondie de la partie supérieure du rail. Sur l'exemple représenté, les extrémités des deux ailes 15 et 16 en vis à vis se touchent au repos, c'est à dire lorsque l'ouvrant 1 n'est pas en place sur le dormant 7, déterminant ainsi une enceinte 14 close à l'intérieur des moyens d'isolation acoustique 9 lorsque la partie saillante 6 de l'ouvrant 1 ne coopère pas avec ces derniers. Un intérêt de cette configuration est d'assurer une surface de contact entre la partie saillante 6 du dormant et les ailes 15 et 16 plus grande en sorte d'améliorer l'isolation acoustique à cette jonction. Un autre intérêt est d'absorber ainsi des tolérances larges de fabrication ou des variantes différentes de forme et d'épaisseur de parties saillantes du dormant, un même profil de moyen d'isolation acoustique pouvant être utilisé dans une pluralité de types de fenêtres à ouvrants coulissant. Cependant, la détermination de l'épaisseur du premier voile 10 devra tenir compte de la force de frottement engendrée par cette surface de contact, qui doit être compatible avec l'effort capable d'être exercé par un opérateur manoeuvrant l'ouvrant.Advantageously, the first web 10 comprises two flexible wings 15, 16 whose respective longitudinal sections decrease in thickness extending towards the end of the wing, in order to constitute a flexible barrier whose flexibility is more and more large when approaching the end of the wings, this end portion of the wings being intended to deform under the effect of the penetration of the projecting element 6 of the frame 7, to ensure contact with it. It should be noted that in the figures, the wings 15 and 16 have been shown undeformed and superimposed on the projecting element 6, in the example adopting the shape of a rail whose upper part is rounded, whereas the opening 1 is in the closed position on the frame 7, to view an example of interception of these two elements. Thus, when the opening is in the appropriate position on the frame, the end of the wings 15 and 16 deforms to substantially and advantageously marry the rounded shape of the upper part of the rail. In the example shown, the ends of the two wings 15 and 16 facing each other touch at rest, that is to say when the opening 1 is not in place on the frame 7, thus determining a closed enclosure 14 inside the sound insulation means 9 when the projecting portion 6 of the opening 1 does not cooperate with these. An advantage of this configuration is to ensure a contact surface between the projecting portion 6 of the frame and the wings 15 and 16 larger so as to improve the sound insulation at this junction. Another advantage is to absorb wide manufacturing tolerances or different variants of shape and thickness of projecting parts of the frame, the same sound insulation means profile can be used in a plurality of types of windows with sliding doors. However, the determination of the thickness of the first web 10 must take into account the friction force generated by this contact surface, which must be compatible with the force that can be exerted by an operator operating the opening.

De manière avantageuse, le premier 10 voile possède une épaisseur différente de celle des deuxièmes 12 ou troisième 13 voiles. En effet, comme représenté sur les figures, les deuxièmes 12 et troisième 13 voiles sont d'une épaisseur similaire, plus grande que celle du premier voile 10, car une fois en place dans l'ouverture interne 8, ces deuxièmes et troisième voiles ne sont plus destinés à se déformer sous l'effet de la mise en place ou du fonctionnement de l'ouvrant, comme c'est la cas du premier voile. Les deuxième et troisième voiles seront de préférence d'une épaisseur maximale afin d'occuper le plus possible l'espace interne 8 en vue de limiter la répercussion des ondes sonores et d'éviter d'entrer en vibration, tout en laissant un espace libre suffisant pour la pénétration de l'élément saillant 6 du dormant 7 et des chariots de roulement (non représentés) pour le côté inférieur du cadre.Advantageously, the first sail has a thickness different from that of the second 12 or third sail 13. Indeed, as shown in the figures, the second 12 and third 13 sails are of a similar thickness, greater than that of the first sail 10, because once in place in the inner opening 8, these second and third sails do not are more likely to deform under the effect of the establishment or operation of the opening, as is the case of the first veil. The second and third webs will preferably be of maximum thickness in order to occupy as much as possible the internal space 8 in order to limit the repercussion of the sound waves and to avoid vibrating while leaving a free space sufficient for the penetration of the projecting element 6 of the frame 7 and the trolleys (not shown) for the lower side of the frame.

Il est à noter que pour permettre la fixation ou l'assise des chariots de roulement, les moyens de filtre acoustique 9 pourront adopter le cas échéant tout aménagement approprié pour que ces chariots puissent prendre appui directement sur le profilé du cadre, par exemple en retirant une partie des voiles aux endroits désirés selon les besoins. Il y a lieu de noter que les chariots pourront le cas échéant être placés en appui sur le troisième voile, pourvoyant ainsi avantageusement à une suspension de l'ouvrant.It should be noted that to enable the fixing or the seat of the trolleys, the acoustic filter means 9 can adopt if necessary any suitable arrangement for these trolleys can bear directly on the profile of the frame, for example by removing some of the sails to the desired locations as needed. It should be noted that the carriages may optionally be placed in abutment on the third sail, thus advantageously providing a suspension of the opening.

Les parois périphériques 4, 5 du cadre 2 comportent à leurs extrémités respectives un joint 17 de type joint brosse, destiné à entrer en contact avec ledit élément saillant 6 du dormant 7 de type rail. Dans l'exemple représenté, le joint brosse 17 est placé dans une rainure interne de chaque paroi périphérique du cadre 2 à la toute extrémité de la paroi, à l'extérieur du périmètre des moyens de filtre acoustique 9. Ainsi, le joint brosse porte sur les flans de l'élément saillant 6 du dormant 7, alors que le premier voile 10 des moyens de filtre acoustique porte sur la partie supérieure de cet élément saillant. Le premier voile 10 conjointement aux brosses confère une excellente isolation acoustique dans cette jonction ouvrant-dormant très sensible à la transmission des ondes sonores. En outre, cette combinaison voile et brosse améliore considérablement l'isolation thermique dans cette zone de jonction, ainsi que l'isolation anti-poussière.The peripheral walls 4, 5 of the frame 2 comprise at their respective ends a seal 17 of the brush seal type intended to come into contact with said projecting element 6 of the frame type frame 7. In the example shown, the brush seal 17 is placed in an internal groove of each peripheral wall of the frame 2 at the end of the wall, outside the perimeter of the acoustic filter means 9. Thus, the door brush seal on the blanks of the projecting element 6 of the frame 7, while the first web 10 of acoustic filter means bears on the upper part of this projecting element. The first web 10 together with the brushes provides excellent acoustic insulation in this opening-dormant junction very sensitive to the transmission of sound waves. In addition, this sail and brush combination significantly improves the thermal insulation in this junction area, as well as the dust insulation.

Comme représenté sur les figures 1 et 2, le profilé 9 moyen de filtre acoustique réalisé avantageusement en caoutchouc ou analogue, peut être inséré aisément en force dans le cadre 2 de l'ouvrant 1 et maintenu en place entre les parois périphériques intérieure 4 et extérieure 5 d'une part, et entre le fond 20 de l'espace interne 8 et des retours 22 pouvant servir de rainures aux profilés brosses le cas échéant.As shown on figures 1 and 2 , the acoustic filter means 9 advantageously made of rubber or the like, can be easily inserted into force in the frame 2 of the opening 1 and held in place between the inner peripheral walls 4 and outer 5 on the one hand, and between the bottom 20 of the internal space 8 and returns 22 can be used as grooves to the brush profiles if necessary.

Il est à noter que dans ce qui précède, ce qui a été dit concernant les moyens de filtre acoustique 9 est applicable aux côtés de l'ouvrant, horizontaux inférieur et supérieur, et vertical en vis à vis du dormant. En général, le côté vertical de l'ouvrant qui n'est pas en vis à vis du dormant, n'a pas lieu d'être équipé des moyens de filtre acoustique décrits plus haut, puisque ce côté de l'ouvrant ne comporte pas d'ouverture périphérique.It should be noted that in what precedes, what has been said about the means of acoustic filter 9 is applicable to the sides of the sash, horizontal lower and upper, and vertical opposite the frame. In general, the vertical side of the opening which is not facing the frame, does not need to be equipped with the acoustic filter means described above, since this side of the opening does not include opening device.
