Abstract
Description
On sait que pour assurer un débit d'air frais sensiblement constant eu égard au débit d'air vicié qui traverse les bouches d'extraction pLacées dans Les pièces de services (cuisine, salle de bain, toiLettes), on a proposé de disposer dans Les pièces d'habitation (chambres ou pièces de séjour) des bouches d'entrée autoréglables comprenant, logé à l'interieur dtun conduit tubulaire, un obturateur en forme de Lame souple maintenue en son mi lieu et apte.à modifier La section de passage de l'orifice de sortie dudit conduit, sous l'effet de la pression différen-tielle régnant au niveau des deux orifices de celui-ci. It is known that in order to ensure a substantially constant flow of fresh air having regard to the flow of stale air which passes through the exhaust vents placed in the service rooms (kitchen, bathroom, tiles), it has been proposed to have in The living rooms (bedrooms or living rooms) with self-adjusting entry vents comprising, housed inside a tubular duct, a shutter in the shape of a flexible blade held in its place and suitable for modification. of the outlet orifice of said conduit, under the effect of the differential pressure prevailing at the two orifices thereof.
Le brevet français BARBARIN NO 74.18513/2.272.346 a pour objet une tel le bouche d'entrée d'air autoréglable, dans laquelle Les orifices d'admission et de sortie du conduit tubulaire sont situés dans deux plans concourants tandis que La lame soupLe constituant obturateur, orientée parallèlement au pLan de L'orifice de sortie, forme un angle compris entre 0 et 450 par rapport à la direction de La veine d'air entrant dans la bouche, et est associée à des moyens de maintien et de cintrage qui agissent au niveau de sa partie centra Le et de part et d'autre de cette dernière en étant agencés de façon a ce qu'en l'absence de pression différentielle, les extrémités de Ladite lame n'obturent pas ledit orifice de sortie. The French patent BARBARIN NO 74.18513 / 2.272.346 relates to such a self-adjusting air inlet mouth, in which the inlet and outlet orifices of the tubular duct are located in two concurrent planes while the flexible blade constituting shutter, oriented parallel to the outlet port plan, forms an angle between 0 and 450 with respect to the direction of the air stream entering the mouth, and is associated with holding and bending means which act at its central portion Le and on either side of the latter being arranged so that in the absence of differential pressure, the ends of said blade do not close said outlet orifice.
Une tel Le construction s'est révéLée particuLièrement avantageuse du fait qu'elle permet la réaLisation d'un dispositif peu encombrant tout en assurant un débit d'entrée d'air important, sans aucun phénomène de battement. De plus, la bouche est susceptible d'être indifféremment montée horizontalement ou verticaLement, ce qui facilite son implantation dans les huisseries. Such a construction has proved to be particularly advantageous in that it allows the realization of a space-saving device while ensuring a high air inlet flow rate, without any fluttering phenomenon. In addition, the mouth is likely to be indifferently mounted horizontally or vertically, which facilitates its implantation in frames.
Toutefois, on peut relever à son encontre Le caractère peu progressif de son fonctionnement. En effet, dès L'apparition d'une différence de pression et même dans Le cas ou cette différence est faible, la lame souple se déforme et vient obturer le passage de l'air à travers le conduit tubulaire, alors qu'il serait avantageux, pour la bonne ventilation du local, que ce passage soit maintenu à un certain débit. However, it can be noted against it The little progressive nature of its operation. Indeed, as soon as a pressure difference appears and even in the case where this difference is small, the flexible blade deforms and closes the passage of air through the tubular conduit, whereas it would be advantageous , for good ventilation of the room, that this passage is maintained at a certain flow rate.
C'est à-cet inconvénient qu'entend remédier la présente invention, laquelle consiste essentiellement à faire comporter aux moyens de maintien et de cintrage associés à la partie centrale de la lame souple d'obturation, une partie profilée à la manière d'une rampe apte à retenir le bord longitudinal correspondant de ladite lame et ainsi à freiner la déformation de celle-ci au niveau de la partie centrale précitée, en maintenant de la sorte une section Libre pour le passage d'un débit significatif d'air frais aussi Longtemps que La différence des pressions extérieure et intérieure n'a pas atteint un certain seuil. It is to this drawback that the present invention intends to remedy, which consists essentially in making the holding and bending means associated with the central part of the flexible shutter blade comprise, a part profiled in the manner of a ramp capable of retaining the corresponding longitudinal edge of said blade and thus slowing the deformation thereof at the aforementioned central part, thereby maintaining a Free section for the passage of a significant flow of fresh air also Long as the difference in external and internal pressures has not reached a certain threshold.
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
Fig. 1 est une vue en perspective illustrant l'agencement d'une bouche d'entrée autoréglable établie conformément à l'invention,
La lame souple d'obturation étant supposée à la position ouverte.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 likely to provide.
Fig. 1 is a perspective view illustrating the arrangement of a self-adjusting inlet mouth established in accordance with the invention,
The flexible shutter blade being assumed to be in the open position.
Fig. 2 est La coupe transversaLe correspondante. Fig. 2 is the corresponding transverse section.
Fig. 3 et 4 reproduisent'fig. 1, respectivement fig. 2, à La position fermée de La lame soupLe. Fig. 3 and 4 reproduce'fig. 1, respectively fig. 2, in the closed position of the flexible blade.
Sur ce dessin, La référence 1 désigne L'huisserie destinée à recevoir la bouche d'entrée suivant L'invention, fixée à L'intérieur du Local au niveau de l'ouverture la pratiquée dans Ladite huisserie 1 pour
Le passage de L'air frais. La structure généraLe du corps 2 de La bouche est sembLable à celLe décrite en détaiL dans Le brevet français BARBARIN NO 74.18513/2.272.346, en ce sens qu'on trouve un conduit tubuLaire dont
L'orifice d'entrée 3 et L'orifice de sortie 4 sont orientés suivant des pLans concourants, l'angle étant ici de 300. A L'intérieur de ce corps 2 est Logé un obturateur formé par une Lame 5 à profiL pLat, susceptibLe de se déformer éLastiquement.In this drawing, the reference 1 designates the frame intended to receive the inlet mouth according to the invention, fixed inside the premises at the opening made in said frame 1 for
The passage of fresh air. The general structure of body 2 of the mouth is similar to that described in detail in French patent BARBARIN NO 74.18513 / 2.272.346, in the sense that there is a tubular conduit whose
The inlet 3 and the outlet 4 are oriented according to concurrent plans, the angle here being 300. Inside this body 2 is housed a shutter formed by a blade 5 with a flat profile, likely to deform elastically.
Comme dans Le cas du brevet précité, Les extrémités (non représen tées) de cette Lame 5 sont simplement guidées dans le corps 2 de manière à pouvoir se dépLacer Librement dans Le sens LongitudinaL. Entre ces deux extrémités, La Lame 5 coopère avec des moyens de maintien et de cintrage anaLogues à ceux décrits dans Le Brevet français précité,
Lesdits moyens prenant La forme de traverses intermédiaires 6 et d'une traverse centraLe 7 soLidaire d'une surface d'appui 7a orientée verticalement.As in the case of the aforementioned patent, the ends (not shown) of this blade 5 are simply guided in the body 2 so as to be able to move freely in the longitudinal direction. Between these two ends, La Lame 5 cooperates with holding and bending means analogous to those described in the aforementioned French patent,
Said means taking the form of intermediate crosspieces 6 and a central cross-member 7 with a support surface 7a oriented vertically.
Conformément à la présente invention, la base 7b de cette surface d'appui 7a est profilée à la manière d'une rampe, en vue de coopérer avec ceLui des bords longitudinaux de la Lame 5 qui est Le plus éloigné des orifices 3 et 4 (bord inférieur sur le dessin annexé). In accordance with the present invention, the base 7b of this bearing surface 7a is profiled in the manner of a ramp, with a view to cooperating with that of the longitudinal edges of the blade 5 which is furthest from the orifices 3 and 4 ( lower edge on the attached drawing).
En fig. 1 et 2, la lame souple 5 a été représentée alors que La pression régnant à L'intérieur du LocaL (côté de L'orifice 4) est substantiellement égale à celle extérieure (c8té orifice 3). En cet état, la rampe 7b assure la retenue du bord longitudinal correspondant de la lame 5. Celle-ci reste bien entendu libre de se déformer de part et d'autre de la traverse centrale 7-7a dès que la pression extérieure commence à se révéler plus élevée que la pression intérieure, en assurant de ce fait la diminution progressive du débit d'entrée d'air à travers la bouche par fermeture progressive de la section libre de passage de orifice de sortie 4. In fig. 1 and 2, the flexible blade 5 has been shown while the pressure prevailing inside the LocaL (side of the orifice 4) is substantially equal to that outside (c8té orifice 3). In this state, the ramp 7b ensures the retention of the corresponding longitudinal edge of the blade 5. The latter naturally remains free to deform on either side of the central cross-member 7-7a as soon as the external pressure begins to reveal higher than the internal pressure, thereby ensuring the gradual reduction of the air inlet flow rate through the mouth by gradual closing of the free passage section of the outlet orifice 4.
Ce n'est que lorsque la pression différentielle dépasse un certain seuil que le bord de la lame 5 va se déplacer le long de la rampe 7b (voir fig. 3 et 4), en autorisant la déformation prononcée de Ladite lame dans sa partie centrale, déformation qui va assurer, au fur et à mesure que la différence des pressions intérieure et extérieure croît, la fermeture pratiquement totale de L'orifice de sortie 4. It is only when the differential pressure exceeds a certain threshold that the edge of the blade 5 will move along the ramp 7b (see fig. 3 and 4), allowing the pronounced deformation of said blade in its central part. , deformation which will ensure, as the difference in internal and external pressures increases, the almost complete closure of the outlet orifice 4.
Il va de soi que le phénomène se produit en sens inverse lorsque la différence des pressions va en diminuant, en opérant ainsi l'ouverture progressive de l'orifice et La modification correspondante du débit d'air à travers La bouche d'entrée. Dans un sens comme dans L'autre, la régulation automatique assurée par la bouche d'entrée d'air suivant l'invention présente bien le caractère progressif recherché. It goes without saying that the phenomenon occurs in the opposite direction when the pressure difference decreases, thereby operating the gradual opening of the orifice and the corresponding modification of the air flow through the inlet mouth. In one direction as in the other, the automatic regulation provided by the air inlet mouth according to the invention does indeed have the desired progressive character.
On comprend qu'en certains cas, la traverse centrale 7 peut comporter deux surfaces parallèles d'appui 7a plus ou moins espacées l'une de l'autre, chacune desdites surfaces 7a étant alors pourvue à sa base d'une partie profilée ou rampe 7b. It is understood that in certain cases, the central cross-member 7 may comprise two parallel bearing surfaces 7a more or less spaced from one another, each of said surfaces 7a then being provided at its base with a profiled part or ramp 7b.
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.
