Description

PORTE AUTOMATIQUE ANTI-DEFLAGRANTE A VANTAUX ACCORDEON
La présente invention se rapporte à une porte automatique anti-déflagrante à vantaux accordéon.
EXPLOSION-PROOF AUTOMATIC DOOR WITH ACCORDION LEAVES
The present invention relates to an explosion-proof automatic door with accordion leaves.

Les portes automatiques à vantaux accordéon qui doivent pouvoir fonctionner en milieu explosif sont équipées d ' un dispositif de commande d ' ouverture et de fermeture qui ne doit, bien entendu, pas être capable de générer d'étincelle susceptible de provoquer une explosion ou un incendie. Pour cette raison, les systèmes de commande électrique sont en pratique à proscrire, car si 1 'on devait utiliser de tels systèmes soumis aux normes d ' anti- déflagration, on aboutirait à des installations plutôt monstrueuses. Accordion leaf automatic doors which must be able to operate in an explosive environment are fitted with an opening and closing control device which, of course, must not be capable of generating a spark capable of causing an explosion or fire . For this reason, electrical control systems are in practice to be avoided, because if one were to use such systems subject to explosion protection standards, it would lead to rather monstrous installations.

Les dispositifs actuels utilisent donc généralement des vérins, pneumatiques ou hydrauliques, à tige, dont le corps est articulé sur la paroi latérale de support de la porte accordéon, et dont la tige a son extrémité libre articulée en un point choisi du premier vantail. Current devices therefore generally use cylinders, pneumatic or hydraulic, with rod, the body of which is articulated on the lateral wall supporting the accordion door, and the rod of which has its free end articulated at a chosen point of the first leaf.

Ces dispositifs connus présentent quelques inconvénients. These known devices have some drawbacks.

s'agissant de portes de relativement faible hauteur, le vérin de commande est nécessairement placé environ à hauteur d'homme, de sorte qu'il est accessible à l'usager qui n a qu'à lever la main pour le toucher, ce qui engendre un risque non négligeable d ' accident corporel pour les utilisateurs. En outre, ce vérin à tige entraîne un fonctionnement saccadé du système d'ouverture et de fermeture de la porte, ce qui n ' est pas très satisfaisant.in the case of doors of relatively low height, the control cylinder is necessarily placed approximately at breast height, so that it is accessible to the user who only has to raise his hand to touch it, which generates a significant risk of bodily injury for users. In addition, this rod cylinder causes jerky operation of the door opening and closing system, which is not very satisfactory.

L'invention vise à remédier à ces inconvénients. Elle se rapporte à cet effet à une porte automatique anti-déflagrante à au moins deux vantaux accordéon adjacents dont le dispositif d'ouverture et de fermeture automatique comporte au moins un vérin pneumatique linéaire plaçé au-dessus ou au dessous de la porte, parallèlement à son arête supérieure ou inférieure en position de fermeture de cette porte; et au moins une came fixée au curseur de ce vérin et possédant une lumière en arc de cercle qui reçoit un pion de guidage solidaire du dernier vantail, à extrémité libre, de cette porte, cette lumière étant conformée pour conférer, par sa coopération avec ce pion, à ce vantail d'extrémité le mouvement de pliure qui est celui qui correspond à celui qu'il doit adopter lors du fonctionnement de la porte. The invention aims to remedy these drawbacks. To this end, it relates to an explosion-proof automatic door with at least two adjacent accordion leaves, the automatic opening and closing device of which comprises at least one linear pneumatic cylinder placed above or below the door, parallel to its upper or lower edge in the closed position of this door; and at least one cam fixed to the slider of this jack and having a light in an arc of a circle which receives a guide pin secured to the last leaf, with a free end, of this door, this light being shaped to confer, by its cooperation with this pin, at this end leaf the folding movement which is that which corresponds to that which it must adopt during the operation of the door.

De toute façon, l'invention sera bien comprise, et ses avantages et autres caractéristiques ressortiront, lors de la description suivante d'une exemple non limitatif de réalisation d une porte automatique double à deux vantaux accordéon pour chaque moitié de cette double-porte, en référence au dessin schématique annexé dans lequel - Figure 1 est une vue d'ensemble de cette double-porte à vantaux accordéon; - Figure 2 est une vue en coupe selon Il-Il de Figure 1; et - Figures 3A,3B,et 3C montrent, en coupe selon III-III de Figure 2, trois positions successives de cette double-porte : fermeture totale, demi-ouverture, et ouverture totale. Anyway, the invention will be well understood, and its advantages and other characteristics will emerge during the following description of a nonlimiting example of embodiment of a double automatic door with two accordion leaves for each half of this double door, with reference to the appended schematic drawing in which - Figure 1 is an overall view of this double door with accordion leaves; - Figure 2 is a sectional view along Il-Il of Figure 1; and - Figures 3A, 3B, and 3C show, in section along III-III of Figure 2, three successive positions of this double door: total closure, half-opening, and total opening.

En se reportant aux figures 1 à 3, il s'agit d'une doubleporte à deux fois deux vantaux accordéon, respectivement 1,2 pour la première moitié de cette porte (moitié gauche sur la figure 1) et 3,4 pour sa seconde moitié. Referring to Figures 1 to 3, it is a double door with twice two accordion leaves, respectively 1.2 for the first half of this door (left half in Figure 1) and 3.4 for its second half.

Cette double-porte est portée par un bâti métallique 5 en forme de portique, et elle est fixée sur les deux montants verticaux 6,7 de ce dernier, les vantaux (1,2 et 3,4) de chaque moitié de porte étant pratiquement montés en porte-à-faux sur le montant 6,7 correspondant, si ce n est qu'ils sont peut-être légérement soutenus par un organe de guidage, respectivement 8 et 9, qui est dans cet exemple constitué par un galopin qui coulisse librement dans une glissière à billes 10 fixée par des attaches il à la traverse supérieure 12 du bâti 5 et joignant les montants 6 et 7. Chacun de ces organes de guidage 8,9 est fixé sur le bord supérieur du dernier vantail 2,4 (à l'extrémité libre 13,14) de la demi-porte accordéon correspondante, à proximité de ladite extrémité libre 13,14. This double door is carried by a metal frame 5 in the form of a gantry, and it is fixed on the two vertical uprights 6,7 of the latter, the leaves (1,2 and 3,4) of each door half being practically mounted cantilever on the corresponding amount 6.7, except that they are perhaps slightly supported by a guide member, respectively 8 and 9, which is in this example constituted by a cantilever which slides freely in a ball bearing 10 fixed by it attaches to the upper cross member 12 of the frame 5 and joining the uprights 6 and 7. Each of these guide members 8, 9 is fixed on the upper edge of the last leaf 2.4 ( at the free end 13,14) of the corresponding accordion half-door, near said free end 13,14.

Conformément à l'invention, chaque couple de vantaux, respectivement 1,2 et 3,4, est mû par un vérin pneumatique linéaire, respectivement 15 et 16, dont le curseur, respectivement 17 et 18, porte une came 19,20 qui est composée d'une plaque métallique maintenue horizontale et percée d ' une lumière 21,22 en arc de cercle. In accordance with the invention, each pair of leaves, respectively 1.2 and 3.4, is driven by a linear pneumatic cylinder, respectively 15 and 16, the cursor of which, respectively 17 and 18, carries a cam 19.20 which is composed of a metal plate kept horizontal and pierced with a light 21,22 in an arc.

Cette lumière 21,22 sert d'organe de guidage pour un pion, respectivement 23 et 24, qu'elle emprisonne et qui est fixé sur l'arête supérieure du vantail d'extrémité 2,4, un peu en retrait, par rapport au bord libre 13 , 14 de ce vantail, de l'organe de guidage correspondant précité 8,9. This light 21,22 serves as a guide member for a pin, respectively 23 and 24, which it traps and which is fixed on the upper edge of the end leaf 2,4, slightly behind, with respect to the free edge 13, 14 of this leaf, of the aforementioned corresponding guide member 8.9.

La forme en arc de cercle de cette lumière 21,22 est choisie pour imposer, par sa coopération avec le pion de guidage correspondant 23,24, à ce vantail d ' extrémité 2,4 et donc également à son vantail adjacent 1,3, le mouvement de pliure qu'il doit adopter lors de l'ouverture ou de la fermeture de la porte. The arc shape of this light 21, 22 is chosen to impose, by its cooperation with the corresponding guide pin 23, 24, on this end leaf 2.4 and therefore also on its adjacent leaf 1.3, the folding movement it must adopt when opening or closing the door.

Ce mode de fonctionnement est bien apparent sur les figures 3A,3B et 3C auxquelles on se reportera maintenant plus particulièrement.  This operating mode is very apparent in FIGS. 3A, 3B and 3C to which reference will now be made more particularly.

La figure 3A montre la double-porte en position de fermeture totale, avec ses quatre vantaux 1 à 4 rigoureusement alignés. Figure 3A shows the double door in the fully closed position, with its four leaves 1 to 4 rigorously aligned.

Dans une telle position, il n' est normalement pas possible d 'ouvrir cette porte-accordéon en exerçant en un ou plusieurs points de celle-ci, par exemple par les vérins linéraires 15 et 16, une force d'ouverture dirigée selon l'axe 26 d'alignement de ces quatres vantaux : en l'absence de composante orthogonale à cet axe 26, il n' est normalement pas possible d' amorcer le mouvement de pliure des vantaux 1 à 4. In such a position, it is normally not possible to open this accordion holder by exerting at one or more points thereof, for example by the linear jacks 15 and 16, an opening force directed according to the axis 26 of alignment of these four leaves: in the absence of a component orthogonal to this axis 26, it is normally not possible to initiate the folding movement of leaves 1 to 4.

Ce mouvement de pliure est, selon un aspect de l'invention, amorçé par la coopération de la lumière en arc de cercle, respectivement 21 et 22, et du pion de guidage qu'elle emprisonne, respectivement 23 et 24. This folding movement is, according to one aspect of the invention, initiated by the cooperation of the light in an arc of a circle, respectively 21 and 22, and of the guide pin which it traps, respectively 23 and 24.

Par suite, lorsque les vérins linéaires 15 et 16 sont alimentés en air comprimé de façon à forcer leurs curseurs 17 et 18 à se déplacer respectivement vers la gauche et vers la droite, les pions 23 et 24 se déplacent dans leurs lumières de guidage 21 et 22 et les vantaux peuvent se plier (figure 3B) jusqu' à ouverture totale de la double-porte (figure 3C). Consequently, when the linear jacks 15 and 16 are supplied with compressed air so as to force their sliders 17 and 18 to move respectively to the left and to the right, the pins 23 and 24 move in their guide lights 21 and 22 and the leaves can fold (Figure 3B) until the double door is fully opened (Figure 3C).

Comme il va de soi, l'invention n'est pas limitée à l'exemple de réalisation qui vient d'être décrit et, par exemple, les organes de guidage 21,23 et/ou 22,24 et les vérins linéaires correspondants 15 et 16 pourraient être plaçés sous la porte. Elle s ' applique aussi bien à des portes accordéon dont le battant unique, ou les deux battants, est ou sont constitués chacun de plus de deux vantaux. Il suffit dans un tel cas de prévoir un couple pion-came semblables à ceux décrits ci-dessus une fois tous les deux vantaux, et de conférer à cette autre came, ou à ces autres cames s ' il y en a plusieurs, un mouvement de translation longitudinale qui dépend de celui de la came d'extrémité de façon à permettre à la porte accordéon d' effectuer normalement ses mouvements d'ouverture et de fermeture.  It goes without saying that the invention is not limited to the embodiment which has just been described and, for example, the guide members 21, 23 and / or 22, 24 and the corresponding linear jacks 15 and 16 could be placed under the door. It also applies to accordion doors whose single leaf, or both leaves, is or are each made up of more than two leaves. In such a case, it suffices to provide a pin-cam couple similar to those described above once every two leaves, and to give this other cam, or these other cams if there are several, a movement. longitudinal translation which depends on that of the end cam so as to allow the accordion door to perform its opening and closing movements normally.
