Abstract
Description
La présente invention est relative à un dispositif d'évacuation rapide des fumées (dit encore "exutoire") et de la chaleur pour des bâtiments tels que, notamment, des locaux industriels ou recevant du public (locaux dits E.R.P. ), permettant, en cas d'incendie, de dégager totalement une trémie délimitant une ouverture dans le toit, soit par déverrouillage, soit par commande manuelle, électromécanique, pneumatique, ou autre. The present invention relates to a device for quickly evacuating smoke (also called "outlet") and heat for buildings such as, in particular, industrial premises or those receiving the public (so-called ERP premises), allowing, in the event fire, to completely free a hopper defining an opening in the roof, either by unlocking, or by manual, electromechanical, pneumatic, or other control.
De tels dispositifs, qui peuvent être également utilisés comme moyens d'aération, constituent des équipements de sécurité devant équiper des usines, ateliers, ou E.R.P. Ils sont en général conçus pour pouvoir intervenir soit automatiquement, soit manuellement, lorsqu'il se produit, par exemple en cas d'incendie, un dégagement de fumées et/ou une élévation anormale de la température ambiante, cette intervention consistant à ouvrir un organe d'obturation mobile recouvrant une ouverture prévue dans le toit du bâtiment, et par laquelle peuvent s'échapper la fumée et la chaleur. Cette intervention automatique permet d'éviter, en cas d'incendie, que tout le batiment ne se remplisse de fumée, afin de mener à bien les opérations d'extinction et d'évacuation du bâtiment. Such devices, which can also be used as aeration means, constitute safety equipment which must equip factories, workshops, or E.R.P. They are generally designed to be able to intervene either automatically or manually, when it occurs, for example in the event of a fire, a release of smoke and / or an abnormal rise in ambient temperature, this intervention consisting in opening an organ mobile shutter covering an opening provided in the roof of the building, and through which smoke and heat can escape. This automatic intervention makes it possible to prevent the entire building from filling up with smoke in the event of a fire, in order to carry out the building's extinguishing and evacuation operations.
I1 existe déjà un certain nombre de systèmes d'évacuation de fumées répondant aux objectifs ci-dessus. Ces systèmes connus consistent, en général, en une trémie délimitant, dans le toit, une ouverture généralement rectangulaire, recouverte par un moyen d'obturation mobile constitué, le plus souvent, par un châssis composé soit d'une plaque de tale ou de polyester, soit de vitres, soit d'une ou de plusieurs coupoles transparentes, soit encore de lames. Ce châssis est articulé sur des paumelles à la traverse haute, l'aération étant obtenue par action sur la traverse basse dudit châssis, à l'aidé de moyens classiques (crémaillère, tringles, bras, etc.). There are already a number of smoke evacuation systems meeting the above objectives. These known systems consist, in general, of a hopper delimiting, in the roof, a generally rectangular opening, covered by a movable closure means constituted, most often, by a frame composed either of a plate of sheet or of polyester , either of windows, or of one or more transparent domes, or even of blades. This chassis is articulated on hinges at the upper cross member, ventilation being obtained by action on the lower cross member of said chassis, using conventional means (rack, rods, arms, etc.).
Les systèmes actuels présentent notamment l'inconvénient d'être complexes et de nécessiter de grandes courses et de grands efforts, et, au moins pour certains d'entre eux, de ne pas dégager totalement l'ouverture de la trémie. Cette invention se propose, en conséquence, d'apporter un dispositif d'évacuation et d'aération qui ne présente pas ces inconvénients. Current systems have the particular disadvantage of being complex and of requiring large strokes and great efforts, and, at least for some of them, of not completely clearing the opening of the hopper. This invention therefore proposes to provide an evacuation and aeration device which does not have these drawbacks.
L'invention a pour objet un dispositif d'aération et d'évacuation des fumées du type décrit ci-dessus, comprenant une trémie sur laquelle repose un châssis mobile, caractérisé en ce que ledit châssis mobile est supporté par un ensemble de quatre bras formant parallélogrammes articulés : deux bras moteurs, et deux bras porteurs dont les longueurs, les angles de débattement et les positions des points de tourillonnement sont choisis de
manière que le châssis mobile bascule en dégageant totalement l'ouverture
de la trémie.The invention relates to a device for aeration and evacuation of fumes of the type described above, comprising a hopper on which a movable frame rests, characterized in that said movable frame is supported by a set of four arms forming articulated parallelograms: two motor arms, and two support arms whose lengths, angles of travel and positions of the pivot points are chosen from
so that the movable frame tilts while completely opening the opening
hopper.
Selon une autre caractéristique de cette invention, la longueur, l'angle
de débattement et les positions des points de tourillonnement des bras du châs
sis mobile, sur les flans de costière et les flans de la trémie, sont choisis
de façon qu'en position d'ouverture, le châssis mobile soit incliné pour assurer
un écoulement des filets d'air optimal pour l'évacuation des fumées.According to another characteristic of this invention, the length, the angle
of deflection and the positions of the journaling points of the arms of the chassis
sis mobile, on the sides of the curb and the sides of the hopper, are chosen
so that in the open position, the movable frame is tilted to ensure
optimal air flow for the evacuation of smoke.
Selon une autre caractéristique de cette invention, les moyens agissant -sur les bras moteurs pour commander -l'ouverture dudit châssis mobile peuvent
être constitués par des ressorts, des vérins à gaz, à ressorts ou électriques,
ou tout dispositif équivalent.According to another characteristic of this invention, the means acting on the drive arms to control the opening of said movable chassis can
be made up of springs, gas, spring or electric cylinders,
or any equivalent device.
Selon une autre caractéristique de cette invention, ledit chassies mobile peut etre constitué soit par une coupole assurant l'éclairage et le désenfumage,
soit par une plaque de tôle, en assurant uniquement le désenfumage, soit en
core par un cadre en tôle comportant, sur l'un de ses versants, un chassis
vitré pouvant être éventuellement mobile.According to another characteristic of this invention, said mobile chases can be constituted either by a dome providing lighting and smoke extraction,
either by a sheet metal plate, ensuring only smoke extraction, or by
core by a sheet metal frame comprising, on one of its slopes, a frame
glazed which can be possibly mobile.
D'autres caractéristiques et avantages de cette invention ressortiront
de la description faite ci-après, en référence aux dessins annexés, qui en il
lustrent un mode de réalisation donné à titre d'exemple non limitatif. Sur les dessins
- la Figure 1 est une vue en élévation et coupe verticale d'un dispositif
selon l'invention, en position de fermeture ; et,
- la Figure 2 est une vue similaire à la Figure 1 représentant, en traits
mixtes, le châssis mobile en position d'ouverture.Other features and advantages of this invention will emerge
of the description given below, with reference to the accompanying drawings, which in it
polish an embodiment given by way of nonlimiting example. On the drawings
- Figure 1 is an elevational view in vertical section of a device
according to the invention, in the closed position; and,
- Figure 2 is a view similar to Figure 1 showing, in lines
mixed, the mobile chassis in the open position.
En se référant aux Figures 1 et 2, on voit que le dispositif selon l'in
vention comprend une trémie 12, de préférence rectangulaire, ménagée dans
la toiture 10 du bâtiment à aérer, à désenfumer, et, le cas échéant, à éclairer.Referring to Figures 1 and 2, it can be seen that the device according to the in
vention comprises a hopper 12, preferably rectangular, arranged in
the roof 10 of the building to be ventilated, to be smoked, and, if necessary, to be lit.
Sur cette trémie 12 est disposé, selon l'invention, un chassies mobile, ou cadre
ouvrant, désigné.dans son ensemble par la référence 14. Ce châssis mobile 14,
reposant sur la trémie, est supporté par quatre bras, formant parallélogrammes articulés
1 - deux bras dits moteurs 16, placés à l'intérieur de l'ensemble trémie
châssis mobile, et tourillonnant d'une part sur les flans de costière,
et d'autre part sur les flans du châssis mobile
2 - deux bras porteurs 18, placés à l'extérieur de l'ensemble trémie-châssis
mobile et tourillonnant, d'une part sur les flans du châssis mobile, et,
d'autre part, sur des plaques telles que 20, fixées sur les flans de costière.On this hopper 12 is arranged, according to the invention, a movable chases, or frame
opening, generally designated by the reference 14. This movable chassis 14,
resting on the hopper, is supported by four arms, forming articulated parallelograms
1 - two so-called motor arms 16, placed inside the hopper assembly
mobile chassis, and swiveling on the one hand on the sides of the curb,
and on the other hand on the blanks of the mobile chassis
2 - two carrying arms 18, placed outside the hopper-chassis assembly
mobile and swiveling, on the one hand on the blanks of the mobile chassis, and,
on the other hand, on plates such as 20, fixed on the curb blanks.
Dans l'exemple de réalisation représenté, le châssis mobile est du type "redent" opaque en tôle. En variante, il pourrait comporter un second châssis
vitré, monté par exemple sur le grand versant 22, ce second châssis pouvant
entre fixe ou ouvrant à l'aide de moyens de commande électrique, pneumatique,
ou autre. Ce second châssis peut, par ailleurs, être plan, classique, avec
petits bois, traverses, vitrage, ou en forme de coupole en matière plastique,
articulée au faîtage.In the embodiment shown, the movable chassis is of the "redent" opaque sheet metal type. Alternatively, it could include a second chassis
glazed, mounted for example on the large slope 22, this second chassis can
between fixed or opening using electrical, pneumatic control means,
Or other. This second chassis can, moreover, be flat, conventional, with
small woods, sleepers, glazing, or in the form of a plastic dome,
articulated to the ridge.
Suivant un autre exemple de réalisation, le châssis mobile 14 peut être
réalisé sous la forme d'une coupole en matière plastique assurant simultané
ment l'éclairage zénithal et le désenfumage.According to another exemplary embodiment, the mobile chassis 14 can be
produced in the form of a plastic dome ensuring simultaneous
the overhead lighting and the smoke extraction.
Suivant encore un autre mode d'exécution, ce cadre mobile peut entre
constitué par un châssis opaque tôlé, en acier ou en alliage léger, servant uni
quement au désenfumage.According to yet another embodiment, this mobile frame can between
constituted by an opaque sheet steel frame, made of steel or light alloy, serving as a plain
only smoke extraction.
Selon l'invention, la longueur, l'angle de débattement et les positions
des points de tourillonnement des bras 16, 18 sont choisis tels qu'à l'ouverture,
le châssis mobile 14 vienne en dehors de la trémie (position 14', Figure 2) et
en position inclinée, pour obenir un écoulement des filets d'air optimal pour
l'évacuation des fumées.According to the invention, the length, the angle of movement and the positions
pivot points of the arms 16, 18 are chosen such that at the opening,
the movable frame 14 comes outside the hopper (position 14 ', Figure 2) and
in an inclined position, to obtain an optimal flow of air streams for
smoke evacuation.
L'ouverture du châssis mobile par basculement autour des points d'ar
ticulation des bras 16, 18, sous la commande des bras moteurs 16, peut être
obtenue par tous moyens classiques, par exemple par déverrouillage, par com
mande mécanique, électromécanique, pneumatique, etc. Dans l'exemple de
réalisation représenté à la Figure 2, la commande est réalisée par déverrouil
lage (automatiquement, comme connu, par exemple à l'aide d'un fusible placé
dans la trémie) et détente de ressorts, tels que 24, ayant une extrémité fixée
sur la trémie, et l'autre extrémité sur une patte soudée respectivement aux
bras 16.The opening of the mobile chassis by tilting around the rear points
ticulation of the arms 16, 18, under the control of the motor arms 16, can be
obtained by any conventional means, for example by unlocking, by com
mechanical, electromechanical, pneumatic control, etc. In the example of
embodiment shown in Figure 2, the control is performed by unlocking
lage (automatically, as known, for example using a fuse placed
in the hopper) and expansion of springs, such as 24, having one end fixed
on the hopper, and the other end on a leg welded respectively to
arm 16.
De la description qui précède, on notera que l'invention apporte un dis
positif permettant d'assurer simultanément l'aération et le désenfumage des
locaux, et éventuellement leur éclairement, lorsqu'on utilise un châssis mobile
vitré, ou en forme de coupole en matière plastique. En outre, grâce aux arti
culations, en forme de parallélogrammes articulés, du châssis mobile 14 sur la trémie 12, on peut mettre enjeu des efforts réduits, en obtenant un rendement élevé pour le désenfumage, ce qui n'est pas possible en général, avec les dispositifs connus.From the above description, it will be noted that the invention provides a dis
positive to simultaneously ensure ventilation and smoke extraction
premises, and possibly their lighting, when using a mobile chassis
glazed, or in the form of a plastic dome. In addition, thanks to the arti
culations, in the form of articulated parallelograms, of the movable chassis 14 on the hopper 12, it is possible to bring into play reduced efforts, obtaining a high efficiency for smoke extraction, which is not generally possible with known devices.
I1 demeure bien entendu que cette invention n'est pas limitée aux exemples de réalisation décrits ou représentés, mais qu'elle en englobe toutes les variantes. I1 remains of course that this invention is not limited to the embodiments described or shown, but that it encompasses all variants.
