Abstract

Between the pinion 13, fixed to the control lever 14, and the pinion 10 operating the door 1 is an air spring 12 attached at eccentric points to these two pinions. In the event of an object 25 being caught as the door 1 closes, the air spring 12 allows the door to be secured while applying to it a constant closing force however much it may be ajar. An interlocking bar 22, operated by a pivoting lever 21, is designed to interlock with a degree of play, the door 1 being in the closed position, with a pivoting rocker bar 6 connected to the door 1. The invention is of particular application to the doors of cable cars. <IMAGE>

Description

La présente invention concerne la commande d'ouverture et de fermeture des portes de véhicules, tels que des cabines de transports par câbles, et elle est plus particulièrement relative à un mécanisme d'ouverture et de fermeture de portes qui assure un verrouillage en position de fermeture tout en tolérant un certain entrebâillement.The present invention relates to the opening and closing control of the doors of vehicles, such as cable transport cabins, and it relates more particularly to a door opening and closing mechanism which ensures locking in the position of closing while tolerating a certain crack.

Les installations de transport de passagers par câbles, en particulier les installations de remontées mécaniques, évoluent dans le sens d'une augmentation des débits de passagers. Cela conduit au chargement des véhicules en marche et entraine de ce fait des conditions tout à fait particulières en ce qui concerne la sécurité de fermeture et d'ouverture des portes de ces véhicules. Ainsi, il arrive qu'au cours de la fermeture des portes de la cabine, après chargement, un objet quelconque se trouve coincé ce qui empêche le verrouillage des portes avec le risque que celles-ci s'ouvrent ensuite de façon inopinée sous l'action d'une force parasite quelconque.Passenger cable transport installations, in particular ski lift installations, are moving in the direction of an increase in passenger flows. This leads to the loading of vehicles in motion and therefore leads to very special conditions regarding the security of closing and opening of the doors of these vehicles. Thus, it happens that during the closing of the doors of the cabin, after loading, any object is stuck which prevents the locking of the doors with the risk that they will then open unexpectedly under the action of any parasitic force.

La présente invention a pour objet essentiel de proposer un mécanisme d'ouverture et de fermeture de portes, qui assure le verrouillage de celles-ci en position de fermeture tout en autorisant un entrebâillement des portes en position de fermeture sous l'effet par exemple du coincement d'un objet quelconque, avec effort constant et contrôlé du coincement, sans compromettre le verrouillage. Avantageusement, le mécanisme selon l'invention est complété par un dispositif de crabotage de sécurité qui détermine le seuil de sécurité admissible en ce qui concerne l'entrebâillement des portes.The main object of the present invention is to propose a mechanism for opening and closing doors, which ensures the locking of the latter in the closed position while allowing the doors to be ajar in the closed position under the effect for example of the jamming of any object, with constant and controlled effort of the jamming, without compromising the locking. Advantageously, the mechanism according to the invention is completed by a safety clutch device which determines the admissible safety threshold with regard to the ajar of the doors.

Selon l'invention le mécanisme d'ouverture et fermeture de portes comprend, associée à chaque porte, une bielle de liaison dont une extrémité est fixée en un point excentré d'un organe tournant de commande entraîné en rotation par un levier de commande d'ouverture et de fermeture et dont l'autre extrémité est fixée en un point excentré d'un organe mobile d'entraînement agissant sur la porte par l'intermédiaire de biellettes pivotantes, le verrouillage de la porte en position d'ouverture comme en position de fermeture étant assuré par un arc-boutement de la bielle de liaison de part et d'autre d'une position médiane d'équilibre. La bielle de liaison comprend un ressort pneumatique qui procure un effort constant sur les extrémités de la bielle fixées aux organes de commande et d'entraînement, quelle que soit la position linéaire de ces extrémités. Ainsi, en cas de coincement d'un objet quelconque entre les vantaux de porte lors de leur manoeuvre de fermeture, le verrouillage de ces vantaux n'est pas empêché et l'effort de coincement appliqué à la porte reste constant, quel que soit l'entrebâillement de celle-ci.According to the invention, the door opening and closing mechanism comprises, associated with each door, a connecting rod, one end of which is fixed at an eccentric point of a rotary control member driven in rotation by a control lever. opening and closing and the other end of which is fixed at an eccentric point of a movable drive member acting on the door by means of pivoting rods, the locking of the door in the open position as in the position closing being ensured by a bracing of the connecting rod on either side of a median position of equilibrium. The connecting rod comprises a pneumatic spring which provides a constant force on the ends of the rod fixed to the control and drive members, whatever the linear position of these ends. Thus, in the event of any object jamming between the door leaves during their closing operation, the locking of these leaves is not prevented and the jamming force applied to the door remains constant, whatever the 'ajar of it.

Avantageusement, un système de crabotage est associé au mécanisme de fermeture et d'ouverture des portes pour assurer une sécurité en position de fermeture verrouillée des portes, et déterminer l'entrebâillement toléré des portes. Le déverrouillage des portes, puis leur ouverture, n'étant possibles qu'après dégagement du système de crabotage par actionnement d'une commande appropriée.Advantageously, a dog clutch system is associated with the closing and opening mechanism of the doors to ensure safety in the locked closing position of the doors, and to determine the tolerated opening of the doors. The unlocking of the doors, then their opening, being possible only after disengaging the dog clutch system by actuation of an appropriate control.

Pour bien faire comprendre le dispositif selon l'invention on en décrira ci-après à , titre d'exemple sans caractère limitatif, une forme d'exécution préférée en référence au dessin schématique annexé dans lequel :

  • la figure 1 est une vue schématique légèrement en perspective, montrant le dispositif selon l'invention appliqué à l'ouverture et à la fermeture d'une porte à deux vantaux, la porte étant représentée en position verrouillée de fermeture ;
  • la figure 2 est une vue analogue à la figure 1 mais montrant les vantaux de porte qui, bien que verrouillés en position de fermeture et crabotés, sont entrebaîllés en raison du coincement entre eux d'un objet ; et
  • la figure 3 est une vue analogue aux figures 1 et 2 mais montrant les vantaux de porte, en position verrouillée de fermeture, qui présentent un entrebâillement trop important pour permettre un crabotage de sécurité.
To make the device clear according to the invention, a preferred embodiment will be described below, by way of example without limitation, with reference to the appended schematic drawing in which:
  • Figure 1 is a schematic view in slightly perspective, showing the device according to the invention applied to the opening and closing of a door with two leaves, the door being shown in the locked closed position;
  • Figure 2 is a view similar to Figure 1 but showing the door leaves which, although locked in the closed position and dogged together, are ajar due to the jamming between them of an object; and
  • FIG. 3 is a view similar to FIGS. 1 and 2 but showing the door leaves, in the locked closing position, which have too much cracking to allow safety interconnection.

En référence au dessin on a représenté en 1,1′ les deux vantaux de porte d'une cabine qui, dans la position complète de fermeture représentée à la figure 1, sont pratiquement jointifs. Chaque vantail 1 est relié, par un couple de biellettes parallèles 2,3, à un arbre vertical 4 monté pour tourner dans des paliers 5 du châssis de la cabine. Une biellette coudée 6 de guidage, articulée à une extrémité en 7 au vantail 1, est montée pivotante à son autre extrémité autour d'un axe 8.Referring to the drawing, there is shown at 1.1 ′ the two door leaves of a cabin which, in the complete closed position shown in FIG. 1, are practically contiguous. Each leaf 1 is connected, by a pair of parallel rods 2,3, to a vertical shaft 4 mounted to rotate in bearings 5 of the chassis of the cabin. A bent guide rod 6, articulated at one end at 7 to the leaf 1, is pivotally mounted at its other end around an axis 8.

L'arbre 4 est solidaire, à sa partie supérieure, d'un pignon denté 9 qui engrène avec un pignon de manoeuvre 10 monté en rotation libre autour d'un axe 11 du châssis de la cabine. Le pignon de manoeuvre 10 est relié par un ressort pneumatique 12 à un pignon de commande 13 solidaire d'un levier de commande 14. Le ressort pneumatique 12 comprend un cylindre 15, dont le fond est solidaire d'une tige 16 articulée en un point excentré 17 du pignon 10, à l'intérieur duquel peut se déplacer un piston dont la tige 18 est articulée en un point 19 excentré du pignon de commande 13. Le pignon 13 engrène avec un pignon 13′ qui, par une chaîne cinématique 12′, 11′, 9′, 4′, 3′, 2′ identique à la chaîne cinématique 12, 11, 9, 4, 3, 2, commande le mouvement du vantail 1′.The shaft 4 is integral, at its upper part, with a toothed pinion 9 which meshes with an operating pinion 10 mounted in free rotation around an axis 11 of the chassis of the cabin. The operating pinion 10 is connected by an air spring 12 to a control pinion 13 secured to a control lever 14. The pneumatic spring 12 comprises a cylinder 15, the bottom of which is secured to a rod 16 articulated at a point eccentric 17 of the pinion 10, inside which can move a piston whose rod 18 is articulated at a point 19 eccentric of the control pinion 13. The pinion 13 meshes with a pinion 13 ′ which, by a kinematic chain 12 ′, 11 ′, 9 ′, 4 ′, 3 ′, 2 ′ identical to the kinematic chain 12, 11, 9, 4, 3, 2, controls the movement of the leaf 1 ′.

A la partie supérieure du châssis de la cabine est articulé, autour d'un axe 20, un levier pivotant 21 qui est solidaire d'une barrette mobile de crabotage 22. Cette barrette 22 présente sa à partie centrale une encoche 23 destinée, dans une position abaissée de la barrette, à venir coiffer avec un certain jeu les biellettes coudées 6,6′ dans la position fermée des vantaux 1,1′ de la porte de cabine.At the upper part of the chassis of the cabin is articulated, around an axis 20, a pivoting lever 21 which is integral with a movable dog clutch bar 22. This bar 22 has at its central part a notch 23 intended, in a lowered position of the bar, to come to cap with a certain play the angled links 6,6 ′ in the closed position of the leaves 1,1 ′ of the cabin door.

Le fonctionnement du dispositif est alors le suivant. Les vantaux 1,1′ de la cabine étant initialement dans leur position ouverte, et le levier 21 dans une position relevée dégageant la barrette 22, l'actionnement du levier 14 dans le sens de la flèche A de la figure 1 provoque la rotation du pignon 13 dont il est solidaire et, par l'intermédiaire du ressort pneumatique 12, la rotation dans le même sens du pignon 10. Ce dernier entraîne en rotation l'arbre 4 pour amener le vantail 1 en position de fermeture. Simultanément le pignon 13 entraîne en rotation le pignon 13′ pour provoquer de façon symétrique la fermeture du vantail 1′ (position de la figure 1). Le verrouillage de chacun des deux vantaux est assuré automatiquement par l'organe de liaison correspondant constitué par le ressort pneumatique 12,12′, lorsque le point d'attache 19, 19′ au pignon 13, 13′, ayant passé le point d'équilibre désigné en 24, 24′ sur l'axe X,X′, présente un arc-boutement irréversible sous l'action d'une force F appliquée au vantail 1,1′ dans le sens de son ouverture. Le levier 21 est rabaissé pour coiffer les biellettes 6,6′ par l'encoche 23 de la barrette de crabotage 22, en agissant comme un dispositif de sécurité pour empêcher la rotation de ces biellettes dans le sens de l'ouverture des vantaux.The operation of the device is then as follows. The leaves 1.1 ′ of the cabin being initially in their open position, and the lever 21 in a raised position releasing the bar 22, the actuation of the lever 14 in the direction of the arrow A in FIG. 1 causes the rotation of the pinion 13 of which it is integral and, by means of the pneumatic spring 12, the rotation in the same direction of the pinion 10. The latter rotates the shaft 4 to bring the leaf 1 into the closed position. Simultaneously the pinion 13 rotates the pinion 13 ′ to cause the leaf 1 ′ to close symmetrically (position in FIG. 1). The locking of each of the two leaves is ensured automatically by the corresponding connecting member constituted by the pneumatic spring 12,12 ′, when the point of attachment 19, 19 ′ to the pinion 13, 13 ′, having passed the point of equilibrium designated at 24, 24 ′ on the X axis, X ′, has an irreversible bracing under the action of a force F applied to the leaf 1.1 ′ in the direction of its opening. The lever 21 is lowered to cover the links 6,6 ′ by the notch 23 of the dog clutch 22, acting as a safety device to prevent the rotation of these links in the direction of opening of the leaves.

Si, comme on l'a représenté à la figure 2, un objet schématisé en 25 se trouve coincé entre les vantaux 1,1′ lors de l'opération de fermeture de ceux-ci, on voit que les pignons 13,13′ atteignent cependant leur position de verrouillage de la porte. Il se produit alors une contraction des ressorts pneumatiques 12,12′, lesquels procurent un effort constant f sur leurs points d'attache 17,17′, 19,19′ quelle que soit la position linéaire de ces points d'attache. Il s'ensuit que l'effort de coincement g des vantaux sur l'objet 25 est constant quel que soit l'entrebâillement de ces vantaux, et que l'objet 25 peut donc être retiré sans compromettre la fermeture totale des vantaux de porte 1,1′ correctement verrouillés. Comme on le voit à la figure 2, la taille de l'objet 25 coincé provoque un entrebâillement des vantaux 1,1′ qui correspond à un écartement des biellettes 6,6′ n'excèdant pas la largeur e de l'encoche 23 de la barrette 22 de crabotage. Cet entrebâillement n'interdit donc pas la mise en place de la barrette 22.If, as shown in FIG. 2, an object shown diagrammatically at 25 is trapped between the leaves 1,1 ′ during the closing operation of these, we see that the pinions 13,13 ′ reach however their door lock position. There then occurs a contraction of the pneumatic springs 12,12 ′, which provide a constant force f on their attachment points 17,17 ′, 19,19 ′ regardless of the linear position of these attachment points. It follows that the clamping force g of the leaves on the object 25 is constant regardless of the cracking of these leaves, and that the object 25 can therefore be removed without compromising the total closure of the door leaves 1 , 1 ′ correctly locked. As can be seen in FIG. 2, the size of the jammed object 25 causes the leaves to open slightly 1.1 ′ which corresponds to a spacing of the links 6.6 ′ not exceeding the width e of the notch 23 of the interconnection bar 22. This half-opening therefore does not prevent the installation of the bar 22.

Si par contre, comme représenté à la figure 3, la taille de l'objet 25′ coincé entre les vantaux 1,1′ est telle que l'entrebâillement de ces vantaux correspond à un écartement des biellettes 6,6′ supérieur à la largeur e de l'encoche 23 de la barrette de crabotage 22, cette barrette ne peut plus venir coiffer les biellettes 6,6′ pour assurer leur verrouillage et le seuil de sécurité admissible à l'écartement de vantaux de porte est alors franchi.If on the other hand, as shown in FIG. 3, the size of the object 25 ′ wedged between the leaves 1,1 ′ is such that the opening of these leaves corresponds to a spacing of the links 6,6 ′ greater than the width e of the notch 23 of the dog clutch bar 22, this bar can no longer come over the connecting rods 6,6 ′ to ensure their locking and the safety threshold admissible for the spacing of door leaves is then crossed.

On comprend donc que c'est la largeur e de l'encoche 23 ménagée dans la barrette de crabotage 22 qui détermine l'entrebâillement admissible des vantaux de porte. On comprend également que, pour l'ouverture des portes, il est d'abord nécessaire de soulever la barrette de crabotage 22 au moyen du levier 21, avant d'actionner le levier de commande 14.It is therefore understood that it is the width e of the notch 23 formed in the dog clutch 22 which determines the admissible cracking of the door leaves. It is also understood that, to open the doors, it is first necessary to lift the dog clutch 22 by means of the lever 21, before actuating the control lever 14.

Au dessin on a représenté respectivement en 26 et 27 des butées portées par le châssis de la cabine et limitant les courses d'ouverture et de fermeture du pignon 13.In the drawing, there are shown respectively at 26 and 27 stops carried by the chassis of the cabin and limiting the opening and closing strokes of the pinion 13.

On notera encore que le dispositif selon l'invention est totalement symétrique par rapport à l'axe vertical Y-Y′ des figures 1 à 3. Cela permet donc le fonctionnement aussi bien d'une porte à vantail unique que d'une porte à deux vantaux. Dans ce dernier cas, les deux vantaux peuvent-être jointifs ou bien coopérer avec un élément intercalaire.It will also be noted that the device according to the invention is completely symmetrical with respect to the vertical axis YY ′ of FIGS. 1 to 3. This therefore allows the operation of a single leaf door as well as of a door with two leaves. In the latter case, the two leaves may be joined or else cooperate with an intermediate element.

On comprendra que la description ci-dessus a été donnée à simple titre d'exemple, sans caractère limitatif, et que des adjonctions ou des modifications constructives pourraient y être apportées sans sortir du cadre de l'invention définie par les revendications qui suivent. Ainsi, sans sortir du cadre de l'invention, les pignons 10, 10′ pourraient être remplacés par des crémaillères ou encore les pignons 13, 13′ pourraient être remplacés par un arbre vertical pivotant centré sur l'axe y-y′.It will be understood that the above description has been given by way of example, without limitation, and that additions or constructive modifications could be made without departing from the scope of the invention defined by the claims which follow. Thus, without departing from the scope of the invention, the pinions 10, 10 ′ could be replaced by racks or the pinions 13, 13 ′ could be replaced by a vertical pivoting shaft centered on the axis y-y ′.
