Abstract

The invention relates to the mechanisms for opening vents for smoke or waste gases, which are placed on a roof enabling a vent cover to be opened by 180 DEG and to be closed easily. It comprises three connecting rods 5, 6 and 7 which are articulated to each other and connected to an arm 8 and to two jacks 2 and 3. In the closed position, the pin 12 and the arm 8 bear on the support 9, the connecting rod 5 compresses the jack 3 under the pressure of the jack 2 and the latter is compressed by the cover 4. The assembly is kept closed by the bolt 1. On opening, the arm is raised by the movement of the three connecting rods under the combined effect of the two jacks.

Description

t) c) d) e)
La présente invention concerne les "exutoires de fumée" qui permettent d'évacuer la fumée d'un bâtiment lors d'un incendie.t) c) d) e)
The present invention relates to "smoke vents" which allow smoke to be removed from a building during a fire.

Dans un local fermé, la fumée et la chaleur dégagée par un incedie montent sous la toîtture puis, envahissent l'ensemble du local. La présence d'ouvertures dans la toiture évacuant la fumée diminue la profondeur de la couche de fumée. L'intervention des moyens d'extinction en est facilitée, la déterioration du båtiment causée par la chaleur diminuée. In a closed room, the smoke and the heat released by a fire go up under the roof then, invade the whole room. The presence of openings in the smoke exhaust roof reduces the depth of the smoke layer. The intervention of the extinguishing means is facilitated, the deterioration of the building caused by the heat reduced.

Ces dispositifs, appellés exutoires de fumée, se composent d'une partie ouvrante formée, dans la présente invention, par un capot ou dôme translucide. L'ouverture du capot ou dôme est commandée à distance manuellement ou automatiquement par fusible thermique et détecteur de fumée. These devices, called smoke vents, consist of an opening part formed, in the present invention, by a translucent hood or dome. The opening of the hood or dome is remotely controlled manually or automatically by thermal fuse and smoke detector.

Un exutoire de fumée doit pouvoir assurer sa fonction quelque soit les conditions météorologiques. Lors de forts vent, la partie ouvrante de l'exutoire peut limiter le débit de celui-ci. dans un cas extrême, si son ouverture est insuffisante par un vent de direction identique au sens d l'ouverture, la fumée est refoulée à l'intérieur du bâtiment. A smoke outlet must be able to perform its function whatever the weather conditions. In strong winds, the opening part of the outlet can limit its flow. in an extreme case, if its opening is insufficient by a wind of direction identical to the direction of opening, the smoke is forced inside the building.

Le mécanisme selon l'invention a pour but d'assurer l'ouverture d'un exutoire par le pivotement sur I800, ou plus, d'un capot ou dôme translucide. The purpose of the mechanism according to the invention is to ensure the opening of an outlet by pivoting on I800, or more, a translucent hood or dome.

Le mécanisme selon l'invention est constitué de trois biellettes droites articulées entre elles, l'ensemble est relié à un bras pivotant autour d'un axe solidaire de la toiture par deux cornières formant support. L'ensemble des trois biellettes est relié par un axe au support. Deux vérins amortisseurs assurent le soulèvement du capot, puis, son basculement par le déploiement des biellettes et la levée du bras. Le capot est maintenu en position rabattue par les deux vérins amortisseurs. The mechanism according to the invention consists of three straight rods hinged together, the assembly is connected to an arm pivoting about an axis integral with the roof by two angles forming a support. All three links are connected by an axis to the support. Two shock absorbers lift the hood, then tilt it by deploying the links and lifting the arm. The cover is held in the folded position by the two damping cylinders.

flans le dessin annexé, le mécanisme selon l'invention est représenté en position repliée en traits continus, en traits discontinus lorsqu'il est déployé. In the accompanying drawing, the mechanism according to the invention is shown in the folded position in solid lines, in broken lines when it is deployed.

Le déploiement du mécanisme, objet de l'invention, a lieu quand le verrou I est ouvert. Le vérin 2 pousse et solève le capot 4, la biellette 5 est libérée de la pression du vériii2 . Sous l'effet combiné de l'inertie du vérin 2 et la poussée du vérin 3 entre les biellettes 5 et 7 , le bras 8 est soulevé. Le capot bascule autour de la charnière 10 par l'intermédiaire du vérin 2.  The deployment of the mechanism, object of the invention, takes place when the latch I is open. The jack 2 pushes and raises the cover 4, the link 5 is released from the pressure of the veriii2. Under the combined effect of the inertia of the actuator 2 and the thrust of the actuator 3 between the links 5 and 7, the arm 8 is raised. The cover swings around the hinge 10 via the jack 2.

)
La fermeture du capot par le repliement du mécanisme, objet de l'invention, peut être éxécutée à la main ou réalisée par le moyen dtune commande à distance agissant sur le capot. La fermeture complète est obtenue par 11 enclenchement du verrou I.)
Closing the cover by folding the mechanism, object of the invention, can be executed by hand or carried out by means of a remote control acting on the cover. Complete closure is obtained by engaging the latch 11.

En tirant par l'intermédiaire d'un cable fixé à un treuil sur le capot 4, le vérin 3 va se rétracter, le bras 8 va se baisser, les biellettes vont se replier, l'axe I2 va venir en appui sur le support 9 , le bras 8 ayant pivoté de 900; le vérin va se rétracter et sa poussée sur la biellette 5 pivotant autour de l'axe I2, va comprimer plus encore le vérin 3 et amener le bras 8 en butée sur le support 9, le verrou I est alors enclanché. By pulling via a cable fixed to a winch on the cover 4, the jack 3 will retract, the arm 8 will fall, the rods will fold, the axis I2 will come to bear on the support 9, the arm 8 having pivoted 900; the jack will retract and its push on the link 5 pivoting around the axis I2, will compress the jack 3 even more and bring the arm 8 into abutment on the support 9, the latch I is then engaged.

Lors des basculements, les contraintes sur le capot 4, la char niere 10 et la sortie de toiture II sont limtées par 11 effet d'amortis sement des vérins et par la répartition des efforts sur le bras 8, sur le support 9. De cette façon la charnière 10 est préservée.  During tilting, the stresses on the cover 4, the hinge 10 and the roof outlet II are limited by the damping effect of the jacks and by the distribution of the forces on the arm 8, on the support 9. From this way the hinge 10 is preserved.
