Description

La présente invention se rapporte à un dispositif d'obturation d'une ouverture d'un conduit aéraulique.The present invention relates to a device for closing an opening of a ventilation duct.

Une ouverture d'un conduit aéraulique est classiquement équipée d'un système d'obturation comprenant un dormant monté dans l'ouverture et un ouvrant, tel qu'un volet ou une trappe, monté mobile sur le dormant entre une position ouverte dans laquelle il libère un passage à travers le dormant, et une position fermée dans laquelle il obture ledit passage. L'ouvrant en position ouverte permet notamment la propagation d'un flux aéraulique vers le conduit, par exemple pour l'aération ou l'évacuation de fumées d'une zone d'un bâtiment, telle qu'un couloir d'évacuation de personnes, en cas de feu.An opening of an air duct is conventionally equipped with a shutter system comprising a frame mounted in the opening and an opening, such as a shutter or a hatch, mounted movably on the frame between an open position in which it releases a passage through the frame, and a closed position in which it closes said passage. The opening in the open position allows the propagation of a ventilation flow towards the duct, for example for aeration or evacuation of smoke from an area of a building, such as a corridor for the evacuation of persons. , in case of fire.

Un système d'obturation connu comporte des moyens motorisés de fermeture de l'ouvrant afin d'éviter une fermeture manuelle de celui-ci. En effet, une fermeture manuelle peut s'avérer rédhibitoire lorsque le bâtiment présente de nombreux ouvrants en position ouverte, par exemple à la suite de déclenchements volontaires pour des essais de sécurité.A known shutter system comprises motorized closing means of the opening to prevent manual closing thereof. Indeed, a manual closure can be prohibitive when the building has many openings in the open position, for example as a result of voluntary triggers for safety tests.

A cet égard, il est notamment connu du document GB 2 200 403 d'utiliser un système d'obturation comportant des moyens motorisés de fermeture de l'ouvrant, montés dans le dormant. Ces moyens motorisés coopèrent avec un câble de rappel reliant l'ouvrant et le dormant, de manière à déplacer l'ouvrant de la position ouverte vers la position fermée.In this respect, it is particularly known from the document GB 2 200 403 to use a shutter system comprising motorized closing means of the opening, mounted in the frame. These motorized means cooperate with a return cable connecting the opening and the frame, so as to move the opening from the open position to the closed position.

Or, ces moyens motorisés disposés dans le dormant obstruent partiellement l'ouverture du conduit lorsque l'ouvrant est en position ouverte, et par là-même conduisent à une perte de charge du flux aéraulique.However, these motorized means arranged in the frame partly obstruct the opening of the duct when the opening is in the open position, and thereby lead to a pressure drop of the air flow.

En outre, cette perte de charge est inversement proportionnelle à la surface de l'ouverture du conduit. Par conséquent, lorsque la surface de l'ouverture du conduit est faible, par exemple pour des conduits étroits, un tel système devient pénalisant.In addition, this pressure drop is inversely proportional to the area of the opening of the duct. Therefore, when the surface of the duct opening is small, for example for narrow ducts, such a system becomes penalizing.

Le document EP 2 031 319 décrit un dispositif d'obturation d'une ouverture d'un conduit aéraulique comportant :

  • un dormant destiné à être monté dans l'ouverture du conduit ;
  • au moins un ouvrant monté mobile sur le dormant, entre une position ouverte dans laquelle il libère un passage à travers le dormant, et une position fermée dans laquelle il obture ledit passage ;
  • des moyens de liaison entre l'ouvrant et le dormant ;
  • des moyens motorisés de fermeture de l'ouvrant, agencés pour coopérer avec les moyens de liaison, de manière à déplacer l'ouvrant de la position ouverte vers la position fermée ;
The document EP 2 031 319 discloses a device for closing an opening of a ventilation duct comprising:
  • a frame intended to be mounted in the opening of the conduit;
  • at least one opening movable on the frame, between an open position in which it releases a passage through the frame, and a closed position in which it closes said passage;
  • connection means between the opening and the frame;
  • motorized closing means of the opening, arranged to cooperate with the connecting means, so as to move the opening from the open position to the closed position;

L'invention vise un dispositif de ce type caractérisé en ce que :

  • les moyens motorisés sont montés sur l'ouvrant,
  • les moyens motorisés sont montés à distance de l'axe de pivotement de l'ouvrant,
  • et les moyens de liaison sont prévus entre les moyens motorisés et le dormant.
The invention relates to a device of this type characterized in that:
  • the motorized means are mounted on the opening,
  • the motorized means are mounted at a distance from the axis of pivoting of the opening,
  • and the connecting means are provided between the motorized means and the frame.

Ainsi, la disposition des moyens motorisés sur un ouvrant permet de dégager l'ouverture du conduit lorsque l'ouvrant est en position ouverte, et donc de limiter la perte de charge du flux aéraulique.Thus, the arrangement of the motorized means on an opening makes it possible to clear the opening of the duct when the door is in the open position, and therefore to limit the pressure drop of the air flow.

Préférentiellement, les moyens motorisés sont montés sur la face interne de l'ouvrant, c'est-à-dire celle tournée du côté du dormant.Preferably, the motorized means are mounted on the inner face of the opening, that is to say that turned to the side of the frame.

Ainsi, la présence des moyens motorisés sur la face interne permet d'obtenir un débattement optimal de l'ouvrant à l'intérieur du conduit. De plus, cette disposition sur la face interne évite des risques de heurts des moyens motorisés contre les parois du conduit lorsque l'ouvrant est déplacé en position ouverte.Thus, the presence of motorized means on the inner face provides an optimal travel of the opening inside the conduit. In addition, this arrangement on the internal face avoids the risk of motorized means clashes against the walls of the duct when the door is moved to the open position.

De manière avantageuse, l'ouvrant présente un bord libre à proximité duquel sont montés les moyens motorisés.Advantageously, the opening has a free edge near which the motorized means are mounted.

Ainsi, en position d'ouverture de l'ouvrant, le dégagement de l'ouverture du conduit est optimal ; les perturbations et la perte de charge du flux aéraulique sont alors réduites.Thus, in the opening position of the opening, the clearance of the opening of the duct is optimal; the disturbances and the pressure drop of the airflow are then reduced.

Avantageusement, l'axe de pivotement est sensiblement vertical.Advantageously, the pivot axis is substantially vertical.

Ainsi, le poids de l'ouvrant s'exerçant sur le dormant est fortement réduit vis-à-vis d'un axe de pivotement horizontal par exemple.Thus, the weight of the opening acting on the frame is greatly reduced vis-à-vis a horizontal pivot axis for example.

Dans une forme d'exécution, les moyens de liaison comportent un câble de rappel présentant une extrémité reliée aux moyens motorisés et une extrémité opposée reliée au dormant.In one embodiment, the connecting means comprise a return cable having an end connected to the motorized means and an opposite end connected to the frame.

Dans une variante d'exécution, les moyens de liaison comportent au moins une biellette présentant une extrémité reliée aux moyens motorisés et une extrémité opposée reliée au dormant.In an alternative embodiment, the connecting means comprise at least one rod having one end connected to the motorized means and an opposite end connected to the frame.

Selon un mode de réalisation, le dispositif selon l'invention comprend :

  • un premier et un second ouvrants ;
  • des moyens de liaison des premier et second ouvrants avec le dormant ;- des moyens motorisés de fermeture montés sur le premier ouvrant ;
    lesdits moyens de liaison étant conçus pour que les moyens motorisés de fermeture déplacent de manière sensiblement concomitante les premier et second ouvrants de la position ouverte vers la position fermée.
According to one embodiment, the device according to the invention comprises:
  • a first and a second opening;
  • means for connecting the first and second openings with the frame; motorized closing means mounted on the first leaf;
    said connecting means being designed so that the motorized closure means substantially concomitantly move the first and second openings from the open position to the closed position.

Selon une première forme de réalisation, les moyens de liaison comportent un câble de rappel passant autour d'une poulie de renvoi disposée sur le dormant, le câble comportant une extrémité reliée aux moyens motorisés et une extrémité opposée reliée au second ouvrant.According to a first embodiment, the connecting means comprise a return cable passing around a return pulley disposed on the frame, the cable having one end connected to the motorized means and an opposite end connected to the second opening.

Selon une seconde forme de réalisation, les moyens de liaison comportent une pluralité de biellettes montées articulées entre elles sur le dormant, la pluralité de biellettes comprenant :

  • une première biellette présentant une extrémité reliée aux moyens motorisés ;
  • une seconde biellette présentant une extrémité reliée au second ouvrant.
According to a second embodiment, the connecting means comprise a plurality of rods mounted articulated to one another on the frame, the plurality of rods comprising:
  • a first rod having an end connected to the motorized means;
  • a second link having an end connected to the second opening.

Ainsi, les moyens de liaisons des première et seconde formes de réalisation permettent de s'affranchir de moyens motorisés de fermeture supplémentaires associés au second ouvrant.Thus, the connecting means of the first and second embodiments make it possible to dispense with additional motorized closing means associated with the second opening.

Par ailleurs, la présence des premier et second ouvrants s'avère particulièrement intéressante vis-à-vis d'un seul ouvrant lorsque l'ouverture du conduit présente une surface importante à obturer.Moreover, the presence of the first and second openings is particularly advantageous vis-à-vis a single opening when the opening of the duct has a large surface to be closed.

Dans un mode de réalisation, les moyens motorisés comportent :

  • un moteur électrique muni d'un arbre de sortie ;
  • un tambour d'enroulement mobile en rotation, et conformé pour recevoir le câble de rappel ;
  • des moyens d'embrayage conçus pour accoupler l'arbre de sortie au tambour ou le désaccoupler.
In one embodiment, the motorized means comprise:
  • an electric motor having an output shaft;
  • a winding drum movable in rotation, and shaped to receive the return cable;
  • clutch means adapted to couple the output shaft to the drum or disengage it.

Les moyens d'embrayage accouplent (respectivement désaccouplent) l'arbre de sortie au tambour au cours du passage de la position ouverte à la position fermée de l'ouvrant (respectivement de la position fermée à la position ouverte). De cette façon, l'effort pour dévider le câble du tambour au cours du passage de la position fermée à la position ouverte est minimisé.The clutch means couples (respectively disengage) the output shaft to the drum during the passage from the open position to the closed position of the opening (respectively from the closed position to the open position). In this way, the effort to unwind the drum cable during the transition from the closed position to the open position is minimized.

De manière avantageuse, le tambour d'enroulement comporte des moyens élastiques agencés d'une part pour mettre en tension le câble de rappel lorsque celui-ci est déroulé autour du tambour au cours du passage de la position fermée à la position ouverte de l'ouvrant, et d'autre part pour mettre en tension le câble de rappel lorsque celui-ci est enroulé autour du tambour au cours du passage de la position ouverte à la position fermée de l'ouvrant.Advantageously, the winding drum comprises elastic means arranged on the one hand to tension the return cable when it is unwound around the drum during the passage of the closed position to the open position of the opening, and secondly to tension the return cable when it is wound around the drum during the transition from the open position to the closed position of the opening .

Ainsi, la mise en tension du câble par les moyens élastiques confère un meilleur guidage du câble autour du tambour, et permet de réduire le risque de formation par le câble d'une boucle ou de noeuds par exemple.Thus, the tensioning of the cable by the elastic means provides better guidance of the cable around the drum, and reduces the risk of formation by the cable of a loop or nodes for example.

Selon une caractéristique, le dispositif selon l'invention comporte en outre des moyens d'ouverture de l'ouvrant conçus pour déplacer l'ouvrant de la position fermée vers la position ouverte.According to one characteristic, the device according to the invention further comprises opening means of the opening designed to move the opening from the closed position to the open position.

Pour les différentes formes d'exécution, les mêmes références pourront être utilisées pour des éléments identiques ou assurant la même fonction, par souci de simplification de la description.For the different embodiments, the same references may be used for identical elements or providing the same function, for the sake of simplification of the description.

Le premier dispositif représenté à la figure 1 comporte un dormant 1 monté dans une ouverture 2 d'un conduit 3 aéraulique. Le conduit 3 est représenté partiellement en traits pointillés. Le dormant 1 présente un cadre formé par deux bords verticaux 10 reliés entre eux par deux bords horizontaux 11.The first device represented in figure 1 comprises a frame 1 mounted in an opening 2 of a duct 3 aeraulic. The duct 3 is partially shown in dashed lines. The frame 1 has a frame formed by two vertical edges 10 interconnected by two horizontal edges 11.

Ce premier dispositif comporte en outre un ouvrant 4 monté pivotant sur les bords horizontaux 11 du dormant 1, autour d'un axe de pivotement X'-X sensiblement vertical, entre une position ouverte dans laquelle il libère un passage à travers le dormant 1, et une position fermée dans laquelle il obture ledit passage.This first device further comprises an opening 4 pivotally mounted on the horizontal edges 11 of the frame 1, about a substantially vertical pivot axis X'-X, between an open position in which it releases a passage through the frame 1, and a closed position in which it closes said passage.

L'ouvrant 4, de forme sensiblement parallélépipédique, présente une face interne 40 tournée du côté du dormant 1. La face interne 40 de l'ouvrant 4 est pourvue de moyens motorisés 5 de fermeture de l'ouvrant 4. Ces moyens motorisés 5 sont centrés sur la face interne 40 suivant la direction de l'axe de pivotement X'-X, et disposés à proximité du bord libre 41 opposé au bord articulé suivant l'axe de pivotement X'-X.The opening 4, of substantially parallelepipedal shape, has an inner face 40 turned on the side of the frame 1. The inner face 40 of the opening 4 is provided with motorized means 5 for closing the opening 4. These motorized means 5 are centered on the inner face 40 in the direction of the pivot axis X'-X, and disposed near the free edge 41 opposite the hinged edge along the pivot axis X'-X.

De plus, ce premier dispositif comporte un câble 6 de rappel présentant une extrémité reliée aux moyens motorisés 5 et une extrémité opposée fixée au bord vertical 10 du dormant 1 opposé à celui équipé de l'axe de pivotement X'-X. Ainsi, le câble 6 forme des moyens de liaisons entre l'ouvrant 4 et le dormant 1.In addition, this first device comprises a return cable 6 having one end connected to the motorized means 5 and an opposite end fixed to the vertical edge 10 of the frame 1 opposite that equipped with the pivot axis X'-X. Thus, the cable 6 forms connecting means between the opening 4 and the frame 1.

Plus précisément, les moyens motorisés 5 illustrés à la figure 5 comportent un moteur 50 électrique muni d'un arbre de sortie 51. De plus, les moyens motorisés 5 comportent un tambour 52 d'enroulement mobile en rotation, et conformé pour recevoir le câble 6, ainsi que des moyens d'embrayage 53 conçus pour accoupler l'arbre de sortie 51 au tambour 52 ou le désaccoupler.More specifically, the motorized means 5 illustrated in FIG. figure 5 comprise an electric motor 50 provided with an output shaft 51. In addition, the motorized means 5 comprise a winding drum 52 movable in rotation, and shaped to receive the cable 6, as well as clutch means 53 designed to coupling the output shaft 51 to the drum 52 or uncoupling.

Les moyens motorisés 5 comportent également un ressort spiral 54 formant des moyens élastiques agissant sur le tambour 52 dans le sens d'enroulement du câble 6, et assurant le maintien en tension du câble 6 lors de son déroulement et lorsque celui-ci est enroulé (respectivement déroulé) autour du tambour 52 au cours du passage de la position ouverte à la position fermée (respectivement de la position fermée à la position ouverte) de l'ouvrant 4.The motorized means 5 also comprise a spiral spring 54 forming elastic means acting on the drum 52 in the winding direction of the cable 6, and ensuring the tensioning of the cable 6 during its unwinding and when it is wound ( respectively unwound) around the drum 52 during the transition from the open position to the closed position (respectively from the closed position to the open position) of the opening 4.

En outre, ce premier dispositif comporte des ressorts (non représentés) reliant l'ouvrant 4 au dormant 1. Ces ressorts forment des moyens d'ouverture pour déplacer l'ouvrant de la position fermée vers la position ouverte. Ces ressorts agissent sur l'ouvrant 4 lorsqu'un dispositif de verrouillage de celui-ci en position fermée est libéré.In addition, this first device comprises springs (not shown) connecting the opening 4 to the frame 1. These springs form opening means for moving the opening from the closed position to the open position. These springs act on the opening 4 when a locking device thereof in the closed position is released.

En ce qui concerne le fonctionnement du premier dispositif, lorsque l'ouvrant 4 est en position fermée, les ressorts sont comprimés et les moyens d'embrayage ont désaccouplé l'arbre de sortie du moteur 50 et le tambour.As regards the operation of the first device, when the opening 4 is in the closed position, the springs are compressed and the clutch means have uncoupled the output shaft of the motor 50 and the drum.

Lorsque l'ouvrant 4 doit être déplacé en position ouverte, par exemple en cas de désenfumage, après que le dispositif de verrouillage de l'ouvrant 4 a libéré celui-ci, les ressorts se détendent et provoquent l'ouverture de l'ouvrant 4. Au cours du passage de la position fermée à la position ouverte, le câble 6 est déroulé autour du tambour 52.When the opening 4 must be moved to the open position, for example in the event of smoke extraction, after the locking device of the opening 4 has released it, the springs relax and cause the opening 4. During the transition from the closed position to the open position, the cable 6 is unwound around the drum 52.

Lorsque l'ouvrant 4 doit être déplacé en position fermée, l'arbre de sortie 51 du moteur 50 est accouplé au tambour 52. Le moteur 50 entraîne alors en rotation le tambour 52. Le câble 6 s'enroule alors autour du tambour 52. Il en résulte un déplacement de l'ouvrant 4 vers la position fermée.When the opening 4 is to be moved to the closed position, the output shaft 51 of the motor 50 is coupled to the drum 52. The motor 50 then rotates the drum 52. The cable 6 then winds around the drum 52. This results in a movement of the opening 4 to the closed position.

Le second dispositif représenté à la figure 2 diffère du premier dispositif en ce qu'il comporte un premier ouvrant 4a et un second ouvrant 4b montés pivotant sur un dormant 1.The second device shown in figure 2 differs from the first device in that it comprises a first opening 4a and a second opening 4b pivotally mounted on a frame 1.

La face interne du premier ouvrant 4a est pourvue de moyens motorisés 5 de fermeture analogues à ceux du premier dispositif.The inner face of the first opening 4a is provided with motorized closing means 5 similar to those of the first device.

Ce dispositif comporte en outre un câble 6 de rappel passant autour d'une poulie 7 de renvoi disposée sur le dormant 1. Le câble 6 présente une extrémité reliée aux moyens motorisés 5, et une extrémité opposée reliée au second ouvrant 4b à proximité du bord vertical de cet ouvrant opposé au bord d'articulation. Ainsi, le câble 6 forme des moyens de liaisons entre les ouvrants 4a, 4b et le dormant 1.This device further comprises a return cable 6 passing around a return pulley 7 disposed on the frame 1. The cable 6 has one end connected to the motorized means 5, and an opposite end connected to the second opening 4b close to the edge vertical opening of this opening opposite the hinge edge. Thus, the cable 6 forms connecting means between the openings 4a, 4b and the frame 1.

Lorsque les ouvrants 4a, 4b doivent être déplacés en position fermée, l'arbre de sortie du moteur 50 est accouplé au tambour 52 afin que le moteur 50 entraîne en rotation le tambour 52. Le câble 6 s'enroule alors autour du tambour 52. Le mouvement du câble 6 s'enroulant autour du tambour est transmis au second ouvrant 4b par l'intermédiaire de la poulie 7. Il en résulte un déplacement du premier ouvrant 4a et du second ouvrant 4b vers la position fermée.When the openings 4a, 4b must be moved to the closed position, the output shaft of the motor 50 is coupled to the drum 52 so that the motor 50 rotates the drum 52. The cable 6 then winds around the drum 52. The movement of the cable 6 wrapping around the drum is transmitted to the second opening 4b through the pulley 7. This results in a displacement of the first opening 4a and the second opening 4b to the closed position.

Le troisième dispositif représenté aux figures 3 et 4 diffère du second dispositif en ce que les moyens de liaison entre les ouvrants 4a, 4b et le dormant 1 sont assurés par une pluralité de biellettes 80, 81, 82, 83, 84.The third device represented in Figures 3 and 4 differs from the second device in that the connection means between the openings 4a, 4b and the frame 1 are provided by a plurality of rods 80, 81, 82, 83, 84.

Le troisième dispositif comporte deux premières biellettes 81, 83, chacune d'elles présentant une première extrémité montée pivotante sur le dormant 1. Ces deux premières biellettes 81, 83 sont rendues solidaires en rotation par une biellette centrale 82 dont les extrémités sont fixées aux tiges des deux premières biellettes 81, 83.The third device comprises two first links 81, 83, each of them having a first end pivotally mounted on the frame 1. These two first links 81, 83 are made integral in rotation by a central rod 82 whose ends are fixed to the rods first two links 81, 83.

Le troisième dispositif comporte en outre deux secondes biellettes 80, 84. La biellette 80 (respectivement biellette 84) présente une première extrémité montée articulée sur la seconde extrémité de la biellette 81 (respectivement biellette 83). La biellette 80 présente une seconde extrémité calée sur l'arbre de sortie 51 du moteur 50 tandis que la biellette 84 présente une seconde extrémité montée pivotante sur l'ouvrant 4b.The third device further comprises two second links 80, 84. The rod 80 (rod 84 respectively) has a first end mounted articulated on the second end of the rod 81 (rod 83 respectively). The link 80 has a second end fitted on the output shaft 51 of the motor 50 while the rod 84 has a second end pivotally mounted on the opening 4b.

Lorsque les ouvrants 4a, 4b doivent être déplacés en position fermée, le moteur 50 entraîne en rotation la biellette 80. Il en résulte une mise en rotation successive des biellettes 81, 83, 84 conduisant au déplacement des ouvrants 4a, 4b vers la position fermée.When the openings 4a, 4b must be moved in the closed position, the motor 50 rotates the rod 80. This results in a successive rotation of the rods 81, 83, 84 leading to the displacement of the openings 4a, 4b to the closed position .
