Abstract

The smoke vent has a skylight frame (1) with a windbreak shutter (7) and receiving a pivoting door leaf (2). The leaf is controlled by a control unit (3) to occupy a close position of an evacuation channel until to its open position. The shutter cooperates with a hook to retain the shutter in a retracted position inside the frame when the leaf occupies an intermediate open position related to a partial closing of the channel under the unit`s effect. The shutter is released beyond the latter position to deploy it relative to articulation axles under the effect of a thrust of a control unit (9).

Description

L'invention concerne un exutoire de désenfumage notamment pour l'évacuation de fumées et l'aération des bâtiments.The invention relates to a smoke evacuation outlet in particular for the evacuation of fumes and aeration buildings.

D'une manière parfaitement connue pour un homme du métier, un exutoire comprend, pour l'essentiel, une costière fixe recevant, avec capacité d'articulation, au moins un vantail ou ouvrant. La costière, généralement de forme parallélépipédique, est fixée par tout moyen connu et approprié, dans une ouverture pratiquée le plus souvent au niveau de la toiture du bâtiment. Le ou les ouvrants sont munis de tout type d'organes de commande, notamment de vérins, afin d'occuper une position de fermeture de la costière correspondant à l'obturation du canal d'évacuation jusqu'à une position totale d'ouverture du canal d'évacuation, cette ouverture pouvant être de l'ordre de 160°. Des positions d'ouverture intermédiaires de l'ouvrant peuvent également être prévues pour réaliser notamment la fonction d'aération.In a manner that is well known to those skilled in the art, an outlet essentially comprises a fixed curb receiving, with articulation capacity, at least one leaf or leaf. The curb, generally of parallelepipedal shape, is fixed by any known and appropriate means, in an opening made most often at the level of the roof of the building. The opening or openings are provided with any type of control members, including cylinders, to occupy a closed position of the curb corresponding to the closure of the discharge channel to a total opening position of the discharge channel, this opening may be of the order of 160 °. Intermediate opening positions of the opening can also be provided to perform in particular the ventilation function.

Pour améliorer le coefficient de débit aéraulique, c'est-à-dire améliorer l'évacuation des fumées au niveau de l'exutoire, quelle que soit l'orientation du vent, on a proposé d'équiper la costière d'éléments faisant office de pare-vent.To improve the ventilation flow coefficient, that is to say improve the evacuation of fumes at the outlet, regardless of the orientation of the wind, it was proposed to equip the curb of elements making office Windbreak.

Une solution ressort par exemple de l'enseignement du brevet FR 2.839.736 . Selon l'enseignement de ce brevet, l'exutoire, en fonction active de désenfumage ou de ventilation, présente une dissymétrie entre la partie avant et la partie arrière de la costière. La partie avant est plus haute que la partie arrière considérée du côté de l'axe d'articulation de l'ouvrant, en vue de son basculement en position d'ouverture. Ce brevet prévoit également de monter, de manière articulée, le pare-vent à l'intérieur de la costière autour d'un axe parallèle à l'axe d'articulation de l'ouvrant, afin que ledit volet se positionne automatiquement en position active lors de l'ouverture du vantail.A solution emerges for example from the teaching of the patent FR 2.839.736 . According to the teaching of this patent, the outlet, in active smoke or ventilation function, has an asymmetry between the front part and the rear part of the curb. The front portion is higher than the rear portion considered on the side of the axis of articulation of the opening, for its tilting in the open position. This patent also provides for mounting, in an articulated manner, the windscreen inside the curb around an axis parallel to the axis of articulation of the opening, so that said flap is automatically positioned in the active position when opening the leaf.

Etant donné que le pare-vent se déploie, de manière simultanée à l'ouverture de l'ouvrant, cela peut poser certains problèmes lorsque ledit ouvrant doit être maintenu en position intermédiaire d'ouverture. En effet, le volet tend à obturer le canal d'évacuation étant donné que ce dernier n'est pas totalement dégagé suite à la position d'ouverture partielle de l'ouvrant généralement inférieure à 90°.Since the windshield deploys simultaneously with the opening of the opening, this can cause some problems when said opening must be maintained in the intermediate open position. Indeed, the flap tends to close the evacuation channel since the latter is not completely clear following the partial opening position of the opening generally less than 90 °.

Pour tenter de remédier à ces inconvénients, le brevet EP 1.380.707 propose une solution qui prévoit des moyens de commande de déploiement du volet pare-vent, de sorte que ledit volet reste escamoté dans une certaine position d'ouverture de l'ouvrant et déployé pour d'autres positions d'ouverture dudit ouvrant. Cependant, d'une manière importante, les moyens techniques susceptibles de réaliser cette fonction ne sont pas divulgués par l'enseignement de ce document.In an attempt to remedy these drawbacks, the patent EP 1.380.707 proposes a solution which provides deployment control means of the windshield, so that said flap remains retracted into a certain opening position of the opening and deployed for other opening positions of said opening. However, in an important way, the technical means likely to achieve this function are not disclosed by the teaching of this document.

A partir de cet état de la technique, le problème que se propose de résoudre l'invention, est de pouvoir, d'une manière concrète, déployer le volet pendant la position d'ouverture de l'ouvrant correspondant au dégagement du canal d'évacuation et d'interdire le déploiement de ce volet lors de l'ouverture intermédiaire dudit ouvrant généralement inférieur à 90° notamment pour réaliser uniquement une fonction d'aération.From this state of the art, the problem to be solved by the invention is to be able, in a concrete manner, to deploy the shutter during the open position of the opening corresponding to the release of the channel. evacuation and prohibit the deployment of the flap during the intermediate opening of said opening generally less than 90 ° in particular to perform only a ventilation function.

Pour résoudre un tel problème, il a été conçu et mis au point un exutoire de fumée comportant une costière recevant, à libre articulation, un ouvrant pivotant sous forme d'un dôme par exemple, assujetti à un organe de commande, ladite costière étant équipée d'un volet pare-vent monté avec capacité de pivotement en étant articulé par rapport à un axe monté à l'intérieur de la costière d'une manière sensiblement parallèle à l'axe d'articulation dudit ouvrant, pour être déployé simultanément à l'ouverture de l'ouvrant. Ledit volet coopère avec des moyens aptes à assurer son maintien en position escamotée à l'intérieur de la costière depuis une position fermée du dôme jusqu'à une position intermédiaire d'ouverture inférieure à 90° par rapport à une verticale passant par le plan de base défini par la costière et sa libération au-delà de ladite position intermédiaire d'ouverture pour permettre, d'une manière concomitante, son déploiement par rapport à son axe de pivotement, sous l'effet de la poussée d'un organe de commande.To solve such a problem, it was designed and developed a smoke outlet comprising a curb receiving, free articulation, a pivoting opening in the form of a dome for example, secured to a control member, said curb being equipped with a wind flap mounted with pivoting capacity being articulated relative to an axis mounted inside the curb in a manner substantially parallel to the axis of articulation of said opening, to be deployed simultaneously with the opening of the opening. Said flap cooperates with means capable of ensuring its holding in the retracted position inside the curb from a closed position of the dome to an intermediate position of opening less than 90 ° with respect to a vertical passing through the plane of base defined by the curb and its release beyond said intermediate opening position to allow, concomitantly, its deployment relative to its pivot axis, under the effect of the thrust of a control member .

Pour résoudre le problème posé de maintenir en position escamotée le volet pare-vent, les moyens sont constitués par un crochet monté avec capacité de déplacement sur une partie de la costière et apte à coopérer avec une ouverture dudit volet.To solve the problem of maintaining in the retracted position the wind-damper, the means consist of a hook mounted with displacement capability on a portion of the curb and adapted to cooperate with an opening of said flap.

Pour résoudre le problème posé de pouvoir libérer le volet pare-vent, en vue de son déploiement, sous l'effet de l'ouverture de l'ouvrant, en position de dégagement total d'évacuation, le crochet est monté avec capacité de déplacement en translation en étant assujetti à un organe élastique de rappel, ledit crochet étant accouplé à un moyen de traction actionnable sous l'effet de pivotement de l'ouvrant, au-delà de la position intermédiaire d'ouverture inférieure à 90°.To solve the problem posed to be able to release the windshield, for deployment, under the effect of the opening of the opening, in total evacuation clearance position, the hook is mounted with displacement capacity in translation being subjected to an elastic return member, said hook being coupled to a traction means operable under the effect of pivoting of the opening, beyond the intermediate opening position of less than 90 °.

Selon une forme de réalisation, le moyen de traction est un câble relié à l'une des extrémités du crochet et à une partie de l'ouvrant.According to one embodiment, the traction means is a cable connected to one end of the hook and to a part of the opening.

Selon une autre forme de réalisation, le moyen de traction est une tringle reliée à l'une des extrémités du crochet et à une partie de l'ouvrant.According to another embodiment, the traction means is a rod connected to one end of the hook and to a part of the opening.

Pour résoudre le problème posé d'actionner le crochet, d'une manière simultanée à l'ouverture de l'ouvrant, et notamment en position d'ouverture totale du canal d'évacuation, la partie de la costière recevant le crochet, est constituée par un profilé monté sensiblement dans la partie médiane de la costière et recevant, à libre articulation, un support où est monté l'organe de commande de l'ouvrant, ledit support présentant des agencements d'accouplement du moyen de traction.To solve the problem of operating the hook, simultaneously with the opening of the opening, and in particular in the fully open position of the discharge channel, the portion of the curb receiving the hook, is constituted by a profile mounted substantially in the middle part of the curb and receiving, free articulation, a support which is mounted on the control member of the opening, said support having arrangements for coupling the traction means.

Pour résoudre le problème posé de permettre le pivotement automatique du volet lorsque le crochet est actionné, le moyen de commande pour le pivotement du volet et constitué par un vérin dont la tige (ou le fût) est solidaire de l'un des bords de la costière et dont le fût (ou la tige) est solidaire d'une partie dudit volet.To solve the problem of allowing the automatic pivoting of the flap when the hook is actuated, the control means for the pivoting of the flap and constituted by a jack whose rod (or the barrel) is integral with one of the edges of the curb and whose shaft (or rod) is secured to a portion of said flap.

Selon une forme de réalisation avantageuse, le volet pare-vent comprend deux côtés parallèles articulés à l'intérieur de la costière au niveau de ses parois latérales, lesdits volets étant reliés, à l'opposé de leur articulation, par un côté transversal disposé au niveau de la paroi transversale avant de la costière considérée à l'opposé de l'articulation de l'ouvrant. Les côtés latéraux parallèles du pare-vent sont profilés pour créer, en position déployée, une dissymétrie entre les parties avant et arrière de la costière.According to an advantageous embodiment, the wind flap comprises two parallel sides articulated inside the curb at its side walls, said flaps being connected, opposite their articulation, by a transverse side disposed at level of the transverse front wall of the curb considered opposite to the hinge of the opening. The parallel lateral sides of the windshield are profiled to create, in the deployed position, an asymmetry between the front and rear parts of the curb.

Comme illustré aux figures des dessins, à titre d'exemple indicatif nullement limitatif, l'exutoire de désenfumage comprend, d'une manière parfaitement connue pour un homme du métier, une costière (1) recevant à libre articulation un ouvrant ou vantail (2) assujetti à un organe de commande (3) pour occuper une position de fermeture du canal d'évacuation délimité par la costière (1) jusqu'à une position totale d'ouverture, de manière à ne créer aucun obstacle au niveau du canal d'évacuation. Entre ces deux positions extrêmes de fermeture, correspondant à l'obturation du canal d'évacuation, et d'ouverture totale, le vantail ou ouvrant (2), sous l'effet de l'organe (3), peut occuper une position intermédiaire correspondant à une obturation partielle du canal d'évacuation afin de réaliser notamment la fonction d'aération.As illustrated in the figures of the drawings, by way of indicative example that is in no way limitative, the smoke extraction outlet comprises, in a manner perfectly known to a person skilled in the art, a curb (1) receiving at free articulation an opening or leaf (2 ) subject to a control member (3) to occupy a closed position of the evacuation channel defined by the curb (1) to a total position opening, so as to create no obstacles at the level of the evacuation channel. Between these two extreme closure positions, corresponding to the closure of the discharge channel, and of total opening, the leaf or opening (2), under the effect of the member (3), can occupy an intermediate position corresponding to a partial closure of the evacuation channel to perform in particular the aeration function.

La conception de base de l'exutoire n'est pas décrite en détail car parfaitement connue par l'homme du métier, et susceptible de présenter différentes formes de réalisation. Il en est de même en ce qui concerne le montage de l'ensemble de l'exutoire de manière étanche dans une partie d'une toiture ou d'ouverture de bâtiment dans un plan horizontal ou incliné. A titre d'exemple, la costière (1) délimite un cadre généralement de forme parallélépipédique, notamment rectangulaire, présentant deux côtés latéraux (1a) et (1b) et deux côtés transversaux (1c) et (1d). L'ouvrant (2), d'une conception parfaitement connue, est destiné à coiffer la costière (1) et est articulé au niveau par exemple du côté (1c) de la costière en étant assujetti à l'organe de commande (3), sous forme d'un vérin. Par exemple, le fût du vérin (3) est articulé sur un support (4) lui-même monté avec capacité d'articulation entre deux fers plats (5) et (6) montés dans la partie médiane de la costière (1), d'une manière parallèle aux côtés latéraux (1a) et (1b). Ces dispositions permettent notamment une ouverture à sensiblement 180° de l'ouvrant (2). La tige du vérin (3) est montée d'une manière articulée avec capacité de déplacement sur une partie de l'ouvrant (2).The basic design of the outlet is not described in detail because it is well known to those skilled in the art and may have different embodiments. It is the same with respect to the assembly of the entire outlet in a sealed manner in a part of a roof or building opening in a horizontal or inclined plane. For example, the curb (1) delimits a generally rectangular parallelepiped-shaped frame, having two lateral sides (1a) and (1b) and two transverse sides (1c) and (1d). The opening (2), of a perfectly known design, is intended to cap the curb (1) and is hinged at the level for example side (1c) of the curb being subject to the control member (3) , in the form of a jack. For example, the barrel of the jack (3) is hinged on a support (4) itself mounted with the ability of articulation between two flat bars (5) and (6) mounted in the middle part of the curb (1), parallel to the lateral sides (1a) and (1b). These arrangements allow in particular an opening substantially 180 ° of the opening (2). The cylinder rod (3) is mounted in an articulated manner with displacement capacity on a part of the opening (2).

Le volet pare-vent désigné dans son ensemble par (7) est par exemple du type de celui décrit dans le brevet FR 2.839.736 . Ainsi, ce volet présente deux côtés latéraux parallèles (7a) et (7b) réunis par un côté transversal (7c). L'ensemble du volet (7) est articulé à l'intérieur de la costière (1). Par exemple, les côtés latéraux (7a) et (7b) sont articulés à leur extrémité libre au moyen d'un axe (8) sur les côtés latéraux (1a) et (1b) à la costière (1). Les axes d'articulation (8) sont disposés sensiblement au niveau de l'axe d'articulation de l'ouvrant (2).The windshield generally designated by (7) is for example of the type described in the patent FR 2.839.736 . Thus, this flap has two parallel lateral sides (7a) and (7b) joined by a transverse side (7c). The entire flap (7) is hinged inside the curb (1). For example, the lateral sides (7a) and (7b) are articulated at their free end by means of an axis (8) on the lateral sides (1a) and (1b) to the curb (1). The hinge pins (8) are arranged substantially at the axis of articulation of the opening (2).

En position escamotée des volets (7) à l'intérieur de la costière (1), le côté transversal (7c) est disposé sensiblement contre la face interne du bord transversal avant de la costière (1). En position déployée du volet (7), les différents bords (7a), (7b), (7c) prolongent vers le haut le canal d'évacuation délimité par la costière (1).In the retracted position of the flaps (7) inside the curb (1), the transverse side (7c) is disposed substantially against the inner face of the front transverse edge of the curb (1). In the deployed position of the flap (7), the various edges (7a), (7b), (7c) extend upwardly the evacuation channel defined by the curb (1).

Selon une caractéristique à la base de l'invention, le volet (7) coopère avec des moyens aptes à assurer son maintien en position escamotée à l'intérieur de la costière depuis une position fermée de l'ouvrant (2) correspondant à l'obturation totale du canal d'évacuation, jusqu'à une position d'ouverture dudit ouvrant (2) inférieure à 90° par rapport à un axe vertical, ou plus généralement, considéré perpendiculairement au plan défini par la costière.According to a characteristic underlying the invention, the flap (7) cooperates with means able to ensure its retention in the retracted position inside the curb from a closed position of the opening (2) corresponding to the total closure of the discharge channel, to an opening position of said opening (2) less than 90 ° with respect to a vertical axis, or more generally, considered perpendicular to the plane defined by the curb.

Soit (α) cette position d'ouverture intermédiaire de l'ouvrant (2) correspondant à une obturation partielle du canal d'évacuation et selon laquelle le volet (7) demeure escamoté à l'intérieur de ladite costière (1) afin de permettre la fonction d'aération. Au-delà de cette position d'ouverture (α), le volet (7) est automatiquement déployé par rapport aux axes d'articulation (8), sous l'effet de la poussée d'un organe de commande (9). Par exemple, cet organe de commande (9) est constitué par un vérin à gaz constituée dont une partie (9), le fut ou la tige, est articulé au bord (7a) et/ou (7b) du volet (7) et dont l'autre partie (9b), la tige ou le fut, est articulée sur le ou les bords latéraux (1a) et/ou (1b) de la costière (1).Let (α) this intermediate opening position of the opening (2) corresponding to a partial closure of the evacuation channel and according to which the flap (7) remains retracted inside said curb (1) in order to allow the ventilation function. Beyond this opening position (α), the flap (7) is automatically deployed relative to the hinge pins (8), under the effect of the thrust of a control member (9). For example, this control member (9) is constituted by a gas cylinder constituted of which part (9), the was or the rod, is articulated to the edge (7a) and / or (7b) of the flap (7) and whose other part (9b), the rod or the is, is hinged to the or the side edges (1a) and / or (1b) of the curb (1).

Les moyens aptes à assurer le maintien en position escamotée du volet (7), sont constitués par un crochet (10) monté avec capacité de déplacement sur une partie de la costière. Plus particulièrement, le crochet (10) est monté avec capacité de déplacement en translation en étant assujetti à un organe élastique de rappel (11). Par exemple, le crochet (10) est monté dans un support (12) solidaire des fers (5) ou (6). En position escamotée, sous l'effet de la détente du ressort (11), le crochet (10) coopère avec une ouverture (7d) que présente le volet (7) au niveau de son bord transversal (7c). Le crochet (10) est accouplé à un moyen de traction (13) actionnable sous l'effet de pivotement de l'ouvrant (2) au-delà de la position d'ouverture (α).The means capable of ensuring the holding in the retracted position of the flap (7), are constituted by a hook (10) mounted with ability to move on a portion of the curb. More particularly, the hook (10) is mounted with translational displacement capacity being secured to an elastic return member (11). For example, the hook (10) is mounted in a support (12) integral with irons (5) or (6). In retracted position, under the effect of the relaxation of the spring (11), the hook (10) cooperates with an opening (7d) that has the flap (7) at its transverse edge (7c). The hook (10) is coupled to a traction means (13) operable under the effect of pivoting the leaf (2) beyond the open position (α).

Les moyens de traction (13) peuvent être constitués par un câble (figures des dessins) ou une tringle. Les moyens de traction (13) peuvent être accouplés à une partie du support d'articulation (4) recevant l'organe de commande (3) de l'ouvrant (2).The traction means (13) may be constituted by a cable (figures of the drawings) or a rod. The traction means (13) can be coupled to a part of the articulation support (4) receiving the control member (3) of the opening (2).

Avantageusement, les côtés latéraux parallèles (7a) et (7b) du pare-vent sont profilés pour créer, en position déployée, une dissymétrie entre les parties avant et arrière de la costière. Cette conception ressort de l'enseignement du brevet précité FR 2.839.736 .Advantageously, the parallel lateral sides (7a) and (7b) of the windscreen are profiled to create, in the deployed position, an asymmetry between the front and rear parts of the curb. This conception is apparent from the teaching of the aforementioned patent FR 2.839.736 .

Compte tenu des caractéristiques à la base de l'invention et des différentes figures des dessins annexées, le fonctionnement de l'exutoire est le suivant :

  • En position fermée de l'ouvrant (2), c'est-à-dire en position d'obturation totale du canal d'évacuation délimitée par la costière (1), le volet pare-vent (7) est maintenu verrouillé en position escamotée à l'intérieur de la costière (1), le crochet (10) étant engagé dans l'ouverture (7d) du volet (figures 1, 4).
  • La commande du vérin (3) pour l'ouverture de l'ouvrant (2), dans la position d'ouverture intermédiaire (α) correspondant à une obturation partielle du canal d'évacuation, ne permet pas le déploiement du pare-vent (7) qui est toujours maintenu verrouillé par le crochet (10) ; dans cette position intermédiaire d'ouverture, l'organe de traction (13) n'est pas sollicité (figures 2, 5, 7).
  • Au-delà de la position d'ouverture intermédiaire (α), sous l'effet du pivotement, notamment du support d'articulation (4), le moyen (13) est soumis à un effort de traction qui provoque, d'une manière concomitante, le déplacement du crochet (10) à l'encontre de l'organe élastique (11) afin de le dégager, d'une manière correspondante, de l'ouverture (1d) du volet (7). D'une manière simultanée, sous l'effet de la poussée exercée par le ou les vérins (9), le volet pare-vent (7) est automatiquement déployé en pivotant par rapport aux axes d'articulation (8) (figures 3, 6, 8).
Given the characteristics underlying the invention and the various figures of the accompanying drawings, the operation of the outlet is as follows:
  • In the closed position of the opening (2), that is to say in the closed position of the exhaust channel delimited by the curb (1), the wind flap (7) is kept locked in the retracted position inside the curb (1), the hook (10) being engaged in the opening (7d) of the flap (FIGS. 1, 4 ).
  • The control of the cylinder (3) for the opening of the opening (2), in the intermediate open position (α) corresponding to a partial closure of the evacuation channel, does not allow the deployment of the windshield ( 7) which is always kept locked by the hook (10); in this intermediate opening position, the traction member (13) is not stressed (Figures 2, 5, 7).
  • Beyond the intermediate opening position (α), under the effect of the pivoting, in particular of the articulation support (4), the means (13) is subjected to a tensile force which causes, in a manner concomitantly, the displacement of the hook (10) against the elastic member (11) in order to disengage it, correspondingly, from the opening (1d) of the flap (7). In a simultaneous manner, under the effect of the thrust exerted by the cylinder (s) (9), the wind-shutter (7) is automatically deployed by pivoting with respect to the hinge pins (8) (FIG. 6, 8).

Les avantages ressortent bien de la description, en particulier on souligne et on rappelle la commande automatique du volet pare-vent au-delà d'un certain angle d'ouverture de l'ouvrant (2) afin de ne pas altérer la fonction aération en position d'ouverture intermédiaire dudit ouvrant.The advantages are apparent from the description, in particular it is emphasized and recalled the automatic control of the windshield beyond a certain opening angle of the opening (2) in order not to alter the aeration function in intermediate opening position of said opening.
