Abstract

Under the deformable closer 10 associated with the exhaust opening 9 of the box 6, 7 a horizontal skin 11 is provided which holds a sound insulation unit 12 which therefore faces the intake opening 8 and ensures effective reduction of external noise without obstructing the passage of air or the functioning of the above-mentioned closer 10.

Description

La présente invention a trait aux bouches d'entrée d'air prévues-au niveau des ouvertures (portes ou fenêtres) d'un local en vue d'assurer
La ventilation de celui-ci.The present invention relates to air intake vents provided at the openings (doors or windows) of a room in order to ensure
The breakdown of it.

On sait qu'on a déjà proposé de faire comporter à de telles bouches d'entrée un obturateur mobile propre à assurer un débit d'air sensiblement constant quelle que soit la différence de pression de part et d'autre de la paroi dans Laquelle est ménagée L'ouverture correspondant à La bouche envisagée. Le Brevet français NO 74 18513/2-272 346 déposé le 22 Mai 1974 au nom de BARBARIN montre une forme de réalisation particulièrement avantageuse d'une telle bouche autoréglabLe. We know that it has already been proposed to make such inlet openings have a movable shutter capable of ensuring a substantially constant air flow whatever the difference in pressure on either side of the wall in which The opening corresponding to the intended mouth. French Patent NO 74 18513 / 2-272 346 filed on May 22, 1974 in the name of BARBARIN shows a particularly advantageous embodiment of such an self-adjusting mouth.

On sait également que les bouches d'entrée d'air à passage direct ou du type autoréglable constituent un pont phonique entre l'extérieur et l'intérieur d'un local. Aussi, en vue de limiter la gêne occasionnée aux occupants du local considéré, on a associé à ces bouches un élément d'isolation acoustique apte à réduire la transmission du bruit. Cet élément est le plus souvent disposé à l'intérieur d'un boîtier d'isolation indépendant, rapporté sur la bouche d'entrée d'air ou sur L'auvent extérieur de protection qui est généralement fixé contre la face de la paroi murale qui est opposée à celle qui porte ladite bouche. It is also known that the air inlet vents with direct passage or of the self-adjusting type constitute a sound bridge between the outside and the inside of a room. Also, in order to limit the discomfort caused to the occupants of the room in question, these mouths have been associated with an acoustic insulation element capable of reducing the transmission of noise. This element is most often placed inside an independent insulation box, attached to the air inlet mouth or to the external protective canopy which is generally fixed against the face of the wall which is opposite to that which carries said mouth.

On conçoit que l'adjonction de ce boîtier d'isolation acoustique à
L'auvent de guidage ou à la bouche elle-même est disgracieuse et encombrante ; de plus elle perturbe fréquemment la circulation de l'air à travers la bouche.It is understood that the addition of this sound insulation box to
The guide or mouth awning itself is unsightly and bulky; moreover it frequently disrupts the circulation of air through the mouth.

C'est à cet inconvénient qu'entend principalement remédier la présente invention, et ce à l'aide d'une bouche d'entrée autoréglable qui incorpore directement un élement d'isolation acoustique sans modifier sensiblement L'encombrement ni L'aspect extérieur de la bouche et sans susciter aucune perturbation dans Le fonctionnement de celle-ci, tout en assurant un affaiblissement acoustique efficace de la transmission du bruit. It is to this drawback that the present invention mainly intends to remedy, and this by means of a self-adjusting inlet mouth which directly incorporates an element of acoustic insulation without appreciably modifying the size or the external appearance of the mouth and without causing any disturbance in the functioning thereof, while ensuring an effective acoustic weakening of the transmission of noise.

La bouche d'entrée d'air suivant l'invention, du genre dans lequel
L'obturateur mobile est Logé à L'intérieur d'un boîtier pourvu d'un orifice d'admission et d'un orifice d'échappement substantiellement orientés à angle droit l'un par rapport à l'autre, en étant disposé parallèlement au plan dudit orifice d'échappement, est caractérisé en ce que l'élément d'isolation acoustique est placé parallèlement au plan précité de l'orifice d'échappement, son bord libre étant situé à une distance telle dudit orifice qu'il se trouve disposé substantiellement au niveau du bord de L'orifice d'admission qui est tourné en direction dudit orifice d'échappement.The air inlet mouth according to the invention, of the kind in which
The mobile shutter is housed inside a housing provided with an inlet and an exhaust orifice substantially oriented at right angles to one another, being arranged parallel to the plane of said exhaust port, is characterized in that the sound-insulating element is placed parallel to the aforementioned plane of the exhaust port, its free edge being located at a distance such that said port is located substantially at the edge of the intake port which faces towards said exhaust port.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer
La figure unique de ce dessin montre en coupe transversale la partie supérieure d'une fenêtre équipée d'une bouche d'entrée d'air autoréglable à isolation acoustique établie conformément à l'invention.The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing.
The single figure of this drawing shows in cross section the upper part of a window equipped with a self-adjusting air inlet mouth with acoustic insulation established in accordance with the invention.

Sur ce dessin, on a supposé que la bouche 1 était fixée contre la face intérieure de l'ouvrant 2 d'une fenêtre à vitrage isolant 3, montée à pivotement à l'intérieur d'un dormant 4. L'ouvrant 2 est découpé d'un conduit de ventilation 2a à profil rectangulaire allongé horizontalement, le débouché de ce conduit 2a étant protégé à l'oppose de la bouche 1 par un auvent classique 5 rapporté contre la face extérieure dudit ouvrant, immédiatement au-dessus du conduit 2a précité. In this drawing, it has been assumed that the mouth 1 was fixed against the inner face of the sash 2 of an insulating glass window 3, pivotally mounted inside a frame 4. The sash 2 is cut out of a ventilation duct 2a with a rectangular profile elongated horizontally, the outlet of this duct 2a being protected opposite the mouth 1 by a conventional canopy 5 fitted against the outside face of said opening, immediately above the aforementioned duct 2a .

Le boîtier de la bouche 1 est formé par l'assemblage de deux pièces démontables, à savoir une embase 6 fixée de manière étanche contre la face intérieure de l'ouvrant 2, et un couvercle amovible 7 à section en
C propre à s'emboîter sur les bords en saillie de l'embase précitée et à être retenu en place par friction. La paroi de L'embase 6 qui est orientée verticalement est découpée d'un orifice d'admission 8 qui concile avec le débouché du conduit 2a, tandis que la paroi horizontale supérieure comporte un orifice d'échappement 9 raidi par des entretoises appropriées.The housing of the mouth 1 is formed by the assembly of two removable parts, namely a base 6 fixed in leaktight manner against the inner face of the opening 2, and a removable cover 7 with a section in
C suitable for fitting onto the projecting edges of the aforementioned base and for being retained in place by friction. The wall of the base 6 which is oriented vertically is cut out from an inlet orifice 8 which conciliates with the outlet of the duct 2a, while the upper horizontal wall has an exhaust orifice 9 stiffened by suitable spacers.

A la manière décrite dans le Brevet français cité au début des prrésentes, le bottier 6-7 ainsi constitué renferme un obturateur mobile d'autoréglage, réalisé sous la forme d'une lame déformable 10 orientée parallèlement à C'orifice d'échappement 9 et dont les extrémités sont maintenues contre La paroi interne du couvercle 7 de façon à venir découvrir ou obturer l'orifice 9 précité, en fonction de la pression d'air régnant de part et d'autre de la porte 2-3 envisagée. In the manner described in the French patent cited at the beginning of the present, the bootmaker 6-7 thus constituted contains a mobile self-adjusting shutter, produced in the form of a deformable blade 10 oriented parallel to the exhaust port 9 and the ends of which are held against the internal wall of the cover 7 so as to uncover or close off the abovementioned orifice 9, as a function of the air pressure prevailing on either side of the door 2-3 envisaged.

Au-dessous de cet orifice d'échappement 9 et à la même hauteur que le bord horizontal supérieur de L'orifice d'admission 8, la paroi verticale du couvercle 7 est solidaire d'une cloison horizontale 11 orientée parallèlement au plan dudit orifice d'échappement, étant observé que la largeur de cette cloison 11 est substantiellement égale à celle de l'orifice 9 précité. Dans le logement horizontal inférieur délimité par la cloison 11, par la paroi antérieure du couvercle 7 et par la paroi horizontale inférieure de ce dernier, est Logé un élément d'insonorisation acoustique 12 réalisé en fibres de verre, en mousse synthétique ou en un autre matériau absorbant d'isolation acoustique. Below this exhaust orifice 9 and at the same height as the upper horizontal edge of the intake orifice 8, the vertical wall of the cover 7 is secured to a horizontal partition 11 oriented parallel to the plane of said orifice d exhaust, it being observed that the width of this partition 11 is substantially equal to that of the abovementioned orifice 9. In the lower horizontal housing delimited by the partition 11, by the front wall of the cover 7 and by the lower horizontal wall of the latter, is housed an acoustic soundproofing element 12 made of glass fibers, synthetic foam or another absorbent sound insulation material.

On conçoit que par suite de sa position à l'intérieur du couvercle 7, cet élément 12 ne perturbe en rien le passage de l'air à travers le boîtier 6-7, ni le fonctionnement de l'obturateur 10 de la bouche d'entrée autoréglable. Néanmoins, sa position face à l'orifice d'admission 8 assure L'amortissement efficace des bruits extérieurs, sans affecter
L'aspect ni l'encombrement de la bouche 1.It is understood that due to its position inside the cover 7, this element 12 in no way disturbs the passage of air through the housing 6-7, nor the operation of the shutter 10 of the mouth of self-adjusting entry. However, its position in front of the inlet 8 ensures effective damping of outside noise, without affecting
The appearance and size of the mouth 1.

Il convient d'observer que la réalisation du boîtier en deux pièces démontables 6 et 7 permet le nettoyage aisé de L'intérieur du dispositif. It should be noted that the realization of the housing in two removable parts 6 and 7 allows easy cleaning of the interior of the device.

Il doit d'ailleurs être entendu que la description qui précède n'a été donnée -qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents.  It should moreover be understood that the foregoing description has been given - only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the details of execution described by all other equivalents.
