Abstract

Self-adjustable air intake port for the ventilation of premises, of the type comprising an obturator formed by a flexible blade (5), the central part of which is capable, through deformation, of regulating the flow rate of fresh air which traverses the tubular conduit provided in the body (1) of the device between an inlet orifice (3) and an outlet orifice (4) which are oriented in concurrent (cooperating) planes, characterised in that the body (1) incorporates, in line with the outlet orifice (4), a balanced valve (8) which under normal operating conditions is oriented so as to totally uncover the abovementioned orifice (4) but which is capable, as soon as a spurious transverse ventilation effect occurs, of tilting so as to close off the said orifice at least partially.

Description

On sait qu'en vue d'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 service (cuisine, salle de bain, toilettes), on a proposé de disposer dans les pièces d'habitation (pièces de séjour ou chambres) des bouches d'entrée autoréglables comprenant, logé à l'in- térieur d'un conduit tubulaire, un obturateur en forme de lame souple maintenue en son milieu et apte à modifier la section de passage de
L'orifice de sortie dudit conduit, par déformation sous L'effet de la pression différentielle 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, toilet), proposed to have self-adjusting entry vents in living rooms (living rooms or bedrooms) comprising, housed inside a tubular duct, a shutter in the form of a flexible blade held in its middle and suitable to modify the passage section of
The outlet orifice of said conduit, by deformation under the effect of the differential pressure prevailing at the two orifices thereof.

Le brevet français BARBARIN NO 74 18513/2.272.346 ainsi que la demande de brevet français BARBARIN ET BARBARIN NO 88 02434/2 627 575 illustrent particulièrement bien ce type d'entrée d'air. The French patent BARBARIN NO 74 18513 / 2.272.346 as well as the French patent application BARBARIN ET BARBARIN NO 88 02 434/2 627 575 illustrate this type of air intake particularly well.

On sait par ailleurs que lorsque de telles bouches auto-réglables sont disposées sur deux façades opposées faisant face à la direction des vents dominants, on se heurte à un effet de ventilation transversale parasite qui perturbe le fonctionnement des bouches considérées et de l'ensemble de l'installation de ventilation du Local, du fait que l'ob- turateur de chacune d'elles n'est plus en mesure de réguler le débit d'air admis. En pareil cas, on doit associer à chaque bouche envisagée un dispositif complémentaire de clapet anti-retour installé en amont de la bouche envisagée, lequel dispositif comprend un boîtier métallique dans lequel est placée une lamelle en matière plastique de faible épaisseur qui sous L'effet de la pression différentielle se soulève pour venir partiellement ou totalement obturer le passage dans le cas d'un flux d'air inversé. We also know that when such self-adjusting vents are arranged on two opposite façades facing the direction of the prevailing winds, we come up against a parasitic transverse ventilation effect which disturbs the operation of the vents considered and of the assembly of the ventilation system of the Room, because the shutter of each of them is no longer able to regulate the air flow admitted. In such a case, an additional non-return valve device installed upstream of the intended mouth must be associated with each envisaged mouth, which device comprises a metal housing in which is placed a thin plastic strip which under the effect differential pressure rises to partially or completely block the passage in the case of an inverted air flow.

Un tel dispositif est généralement monté en traversée du mur extérieur ou logé dans le doublage et l'on conçoit que son montage est ma laisé et aboutit à un ensemble disgraçieux, présentant un encombrement important correspondant en pratique au double de celui d'une bouche non équipée d'un clapet. Such a device is generally mounted crossing the outer wall or housed in the lining and it is understandable that its mounting is easy and results in an unsightly assembly, having a large size corresponding in practice to twice that of a non-mouth equipped with a valve.

C'est à cet inconvénient qu'entend remédier la présente invention, laquelle consiste essentiellement à faire directement comporter à la partie du corps de la bouche disposée au droit de L'orifice de sortie du conduit de celle-ci, un clapet équilibré qui dans Les conditions normales de fonctionnement est orienté vers le haut en découvrant L'orifice sus-mentionné mais qui est apte, dès qu'un effet de ventilation trans versa Le parasite survient, à basculer vers le bas en s'appliquant contre ledit orifice qui est ainsi obturé au moins de manière partielle, quelle que soit à cet instant La position affectée par L'obturateur de La bouche envisagée. It is to this drawback that the present invention intends to remedy, which consists essentially in making the part of the body of the mouth directly arranged in line with the outlet orifice of the conduit thereof have a balanced valve which in The normal operating conditions are directed upwards by uncovering the above-mentioned orifice but which is capable, as soon as a transverse ventilation effect the parasite occurs, of tilting downwards by applying against said orifice which is thus closed at least partially, whatever the position affected by the shutter of the intended mouth at this instant.

Conformément à un mode de mise en oeuvre préféré de la disposition qui précède, le clapet équilibré est constitué par une pièce monobloc réalisée en une matière synthétique rigide ou semi-rigide, laquelle pièce comprend un voLet Longitudinal plan qui se raccorde, par un renflement pourvu de pivots métalliques à ses extrémités, à un talon surépaissi propre à jouer le rôle de contrepoids d'équilibrage. In accordance with a preferred embodiment of the above arrangement, the balanced valve consists of a single piece made of a rigid or semi-rigid synthetic material, which piece comprises a plane longitudinal plane which is connected, by a bulge provided of metal pivots at its ends, with a thickened heel capable of playing the role of balancing counterweight.

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 illustre en coupe l'agencement d'une bouche d'entrée autoréglable établie suivant La présente invention, le clapet antiretour intégré étant représenté à la position haute 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 capable of providing.
Fig. 1 illustrates in section the arrangement of a self-adjusting inlet mouth established according to the present invention, the integrated non-return valve being shown in the high open position.

Fig. 2 est une coupe transversale à plus grande échelle, le clapet intégré étant ici représenté à la position basse de fermeture. Fig. 2 is a cross section on a larger scale, the integrated valve here being shown in the low closed position.

La structure générale de la bouche suivant fig. 1 et 2 est semblable à celle décrite et illustrée dans la demande de brevet français NO 88 02434/2 627 575 susvisée, en ce sens qu'on trouve un corps creux 1 destiné à être fixé à l'intérieur d'un local au niveau d'une ouverture 2a pratiquée dans la partie supérieure d'une huisserie 2 pour le passage de L'air frais.L'orifice d'admission 3 et L'orifice de sortie 4 du conduit tubulaire délimité à l'intérieur du corps 1 sont orientés suivant des plans concourants, la régulation du débit d'air qui traverse Ledit conduit étant opérée à L'aide d'un obturateur formé par une lame élastiquement déformable 5 à profil plat ; les extrémités de cette lame ou obturateur 5 sont guidées dans le corps 1 de façon à être susceptibles de se déplacer longitudinalement en permettant la libre déformation de la partie centrale Entre ses deux extrémités, la lame 5 coopère avec des moyens de maintien et de cintrage formés par des traverses intermédiaires 6 et deux traverses centrales 7, ces dernières étant convenablement profilées pour permettre le fonctionnement de L'obturateur
Conformément à la présente invention, on a directement intégré à la partie supérieure du corps 1 deux clapets anti-retour 8, prévus entre chacune des deux traverses centrales 7 et le bord d'extrémité correspondant de L'orifice de sortie 4. The general structure of the mouth according to fig. 1 and 2 is similar to that described and illustrated in the French patent application NO 88 02 434/2 627 575 above, in that there is a hollow body 1 intended to be fixed inside a room at the level an opening 2a made in the upper part of a frame 2 for the passage of fresh air. The inlet orifice 3 and the outlet orifice 4 of the tubular conduit delimited inside the body 1 are oriented along concurrent planes, the regulation of the air flow which passes through said duct being effected using a shutter formed by an elastically deformable blade 5 with a flat profile; the ends of this blade or shutter 5 are guided in the body 1 so as to be able to move longitudinally allowing the free deformation of the central part Between its two ends, the blade 5 cooperates with holding and bending means formed by intermediate crosspieces 6 and two central crosspieces 7, the latter being suitably profiled to allow the operation of the shutter
According to the present invention, two non-return valves 8, provided between each of the two central crosspieces 7 and the corresponding end edge of the outlet orifice 4, have been directly integrated into the upper part of the body 1.

Comme plus particulièrement illustré en fig. 2, chaque clapet 8, constitué par une pièce monobloc obtenue par moulage d'une matière synthétique rigide ou semi-rigide, présente un volet 8a à profil plat dont le bord longitudinal supérieur se raccorde à un renflement 8b éta bli à une section circulaire ; ce renflement 8b, simplement engagé entre les bords longitudinaux opposés d'une fente horizontale la pratiquée dans la partie supérieure du corps 1, comporte à ses extrémités des tiges métalliques qui pivotent librement dans des logements latéraux cor respondants prévus dans le corps 1 en permettant le basculement du clapet 8.Ce renflement 8b se raccorde lui-meme à un talon massif 8c, présentant en section un profil rectangulaire ou carré apte à s'intégrer à l'intérieur d'un logement interne lb qui est prévu dans la partie supérieure du corps 1 et dont les parois horizontales opposées limitent l'amplitude de basculement du clapet. As more particularly illustrated in fig. 2, each valve 8, consisting of a single piece obtained by molding a rigid or semi-rigid synthetic material, has a flap 8a with a flat profile, the upper longitudinal edge of which is connected to a bulge 8b established in a circular section; this bulge 8b, simply engaged between the opposite longitudinal edges of a horizontal slot made in the upper part of the body 1, comprises at its ends metal rods which pivot freely in corresponding lateral housings provided in the body 1 allowing the tilting of the valve 8.This bulge 8b connects itself to a solid heel 8c, having in section a rectangular or square profile able to be integrated inside an internal housing lb which is provided in the upper part of the body 1 and whose opposite horizontal walls limit the amplitude of tilting of the valve.

On conçoit que Le talon 8c peut être établi de manière à former contrepoids, équilibrant le clapet 8 de façon telle qu'à la position normale de fonctionnement de la bouche autoréglable, c'est-à-dire en
L'absence de tout effet de ventilation transversaLe parasite, ledit clapet soit orienté à la manière illustrée en trait plein en fig. 1 et en trait interrompu (8') en fig. 2, le volet 8a étant alors tourné vers le haut en découvrant totalement L'orifice de sortie 4. Par contre, dès qu'apparaît une circulation parasite sous L'effet d'une ventilation transversale due à un courant d'air qui s'établit entre les bouches d'air disposées sur Les deux façades opposées du local, l'équilibre du clapet 5 est rompu et Ledit cLapet bascule vers Le bas en obturant au moins partiellement L'orifice de sortie 4 ; L'effet parasite cesse immédiatement.It is understood that the heel 8c can be established so as to form a counterweight, balancing the valve 8 so that in the normal operating position of the self-adjusting mouth, that is to say in
The absence of any transverse ventilation effect. The parasite, said valve is oriented as shown in solid lines in FIG. 1 and in broken lines (8 ') in fig. 2, the flap 8a then being turned upwards, completely revealing the outlet orifice 4. On the other hand, as soon as parasitic circulation appears under the effect of transverse ventilation due to an air current which establishes between the air vents arranged on the two opposite facades of the room, the balance of the valve 5 is broken and said valve flips downward at least partially closing the outlet orifice 4; The parasitic effect immediately ceases.

Il convient d'observer qu'on peut obtenir un fonctionnement très sensible du clapet anti-retour 8 moyennant un calcul précis des dimensions du talon 8c ; des essais sur un prototype ont démontré que le basculement du clapet peut intervenir sous L'effet de pressions de L'ordre de deux à trois pascals. On notera sur ce point qu'en vue d'améliorer la sensibilité, on peut faire comporter aux bords longitudinaux de la fente la un rebord présentant en section un profil concave apte à tenir lieu de palier pour le renflement 8b. It should be noted that very sensitive operation of the non-return valve 8 can be obtained by precise calculation of the dimensions of the heel 8c; tests on a prototype have shown that the tilting of the valve can occur under the effect of pressures of the order of two to three pascals. It will be noted on this point that in order to improve the sensitivity, the longitudinal edges of the slot 1 may be made to have a rim having in section a concave profile capable of serving as a bearing for the bulge 8b.

L'encombrement général d'une bouche à clapet intégré suivant l'in- vention est pratiquement identique à celui d'une bouche non équipée d'un clapet, tandis que l'aspect d'ensemble n'est pas modifié par L'intégra- tion de celui-ci. On notera que la bouche d'entrée peut indifféremment fonctionner surU;ny#paroi horizontale ou suruneparoi verticale,
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. On comprend en particulier que le nombre de cLapets montés dans La bouche dépend de la longueur de celle-ci et peut en conséquence varier dans une mesure considérable. The overall dimensions of an integrated valve mouth according to the invention is practically identical to that of a mouth without a valve, while the overall appearance is not modified by The integrated - tion of it. It will be noted that the inlet mouth can equally function on U; ny # horizontal wall or on a vertical wall,
It should moreover be understood that the above 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 execution details described by all other equivalents. It is understood in particular that the number of valves mounted in the mouth depends on the length thereof and can therefore vary to a considerable extent.
