Abstract

A mechanism for opening, closing and locking doors with two leaves for cable cars, wherein the two leaves of a car door are controlled at the top and the bottom by a crank lever integral with a control piece movable horizontally in the vertical plane of symmetry of the two door leaves. Each crank lever acts on a horizontal toggle joint with dead point clearance whose links are pivotally secured respectively to levers rotating about fixed vertical axes forming the axes of rotation of the two door leaves, said levers being connected respectively to the radial arms of the door leaves by resilient connections providing locked closure of the leaves even if one of them is held slightly open.

Description

Les installations de transport de passagers par câble, de remontées mécaniques en particulier, évoluent dans le sens d'une forte augmentation du nombre de passagers dans un temps donné, c'est-à-dire d'une forte augmentation du débit des installations de transport.Passenger cable transport installations, in particular for ski lifts, are moving in the direction of a large increase in the number of passengers in a given time, that is to say a large increase in the throughput of transport.

Dans les installations qui utilisent des cabines, l'amélioration des débits nécessite des véhicules qui doivent permettre le chargement et le déchargement rapide du plus grand nombre de passagers possible dans un volume de cabine aussi réduit que possible compatible avec les possibilités de l'installation comportant les véhicules, ce qui conduit à l'utilisation de cabines à accès de grandes dimensions, en particulier à travers une porte à deux vantaux qui peuvent s'ouvrir le long de la carrosserie, soit à l'intérieur, soit à l'extérieur de cette carrosserie.In installations using cabins, the improvement in throughputs requires vehicles which must allow the rapid loading and unloading of the greatest possible number of passengers in a cabin volume as small as possible compatible with the possibilities of the installation comprising vehicles, which leads to the use of large access cabins, in particular through a door with two leaves which can open along the bodywork, either inside or outside this bodywork.

On a proposé, par le document FR-A-2 240 133 des mêmes déposants, un mécanisme d'actionnement des deux vantaux de porte coulissants, symétriques par rapport à un plan vertical, équipant une cabine de transport de passagers par câble. Ce mécanisme d'actionnement comporte une pièce de commande pivotante qui actionne une genouillère pratiquement horizontale à franchissement de point mort, laquelle est composée de deux biellettes symétriques actionnant chacune un levier relié à l'un des vantaux par un bras articulé. Chaque levier, à son extrémité opposée au bras articulé, peut présenter un déplacement limité dans une fente oblongue contre l'action d'un ressort de rappel. Un tel mécanisme assure l'irréversibilité du verrouillage des portes en position de fermeture, mais permet un certain entrebaîllement des vantaux sous l'effet d'un obstacle coincé entre un vantail et la paroi fixe.Document FR-A-2 240 133 from the same applicants has proposed a mechanism for actuating the two sliding door leaves, symmetrical with respect to a vertical plane, fitted to a cable passenger cabin. This actuating mechanism comprises a pivoting control part which actuates a practically horizontal toggle lever with crossing of neutral point, which is composed of two symmetrical rods each actuating a lever connected to one of the leaves by an articulated arm. Each lever, at its end opposite the articulated arm, can have a limited displacement in an oblong slot against the action of a return spring. Such a mechanism ensures the irreversibility of the locking of the doors in the closed position, but allows a certain cracking of the leaves under the effect of an obstacle wedged between a leaf and the fixed wall.

La présente invention concerne un mécanisme d'ouverture, de fermeture et de verrouillage assurant l'irréversibilité du verrouillage tout en tolérant un certain entrebaîllement des vantaux sous l'effet d'un obstacle coincé entre ces vantaux sans compromettre pour autant le verrouillage assuré par l'irréversibilité de la commande en position de fermeture qui s'opposé à la manoeuvre d'ouverture sous l'action d'une force parasite quelconque exercée sur les vantaux. Elle a pour but essentiel un tel mécanisme dont les éléments travaillent strictement dans un plan horizontal, malgré l'utilisation du système de commande habituel à levier actionné par des rampes inclinées et pivotant dans un plan vertical, en évitant les contraintes de torsion et qui peut être utilisé sans risques de coincement dans des cabines transportant des passagers debout (donc avec des vantaux très hauts) car il permet un actionnement simultané du haut et du bas de la porte.The present invention relates to an opening, closing and locking mechanism ensuring the irreversibility of the locking while tolerating a certain opening of the leaves under the effect of an obstacle wedged between these leaves without compromising the locking provided by the irreversibility of the control in the closed position which opposes the opening operation under the action of any parasitic force exerted on the leaves. Its essential purpose is such a mechanism, the elements of which work strictly in a horizontal plane, despite the use of the usual lever control system actuated by inclined ramps and pivoting in a vertical plane, avoiding torsional stresses and which can be used without risk of jamming in cabins carrying standing passengers (therefore with very high leaves) because it allows simultaneous actuation of the top and bottom of the door.

Selon l'invention, le mécanisme d'actionnement d'une porte à deux vantaux symétriques l'un de l'autre par rappport à un plan vertical et montés sur une cabine de transport de passagers par câble comprend, à l'une des extrémités de la hauteur des vantaux, une manette de commande pivotante actionnant une genouillère horizontale à franchissement de point mort composée de deux biellettes symétriques qui actionnent deux leviers reliés au moins à deux bras mobiles reliés chacun à l'un des deux vantaux, un montage élastique étant prévu entre chaque vantail et la biellette associée pour permettre, en position de fermeture, un déplacement limité de chaque vantail vers sa position d'ouverture et par conséquent l'entrebaîllement des vantaux en position de fermeture verrouillée par la position de la genouillère amenée au-delà de son point mort, et il se caractérisé en ce que la manette pivotante agit sur les biellettes par l'intermédiaire d'une pièce de commande qui présente un mouvement horizontal parallèlement au plan vertical de symétrie des deux vantaux, ladite pièce de commande étant solidaire d'un maneton qui actionne ladite genouillère.According to the invention, the mechanism for actuating a door with two leaves which are symmetrical to each other by reference to a vertical plane and mounted on a cable passenger cabin comprises, at one of the ends of the height of the leaves, a pivoting control lever actuating a horizontal knee lever with crossing neutral point composed of two symmetrical rods which actuate two levers connected at least to two movable arms each connected to one of the two leaves, an elastic mounting being provided between each leaf and the associated rod to allow, in the closed position, a limited movement of each leaf towards its open position and consequently the half-opening of the leaves in the closed position locked by the position of the toggle brought to- beyond its neutral point, and it is characterized in that the pivoting lever acts on the rods by means of a control part which has a horizontal movement l parallel to the vertical plane of symmetry of the two leaves, said control part being integral with a crank pin which actuates said toggle joint.

La commande définie ci-dessus peut être en haut ou en bas de la porte, mais on peut aussi prévoir deux commandes identiques prévues respectivement en haut et en bas et reliées entre elles par une transmission verticale. En outre, dans le cas d'une seule commande à liaison élastique, par exemple en haut d'une porte à deux vantaux de faible hauteur, la commande unique peut agir sur un moyen vertical de transmission capable d'actionner en bas de porte un verrouillage permettant un entrebâillement limité.The command defined above can be at the top or bottom of the door, but one can also provide two identical commands provided respectively at the top and bottom and connected together by a vertical transmission. In addition, in the case of a single control with elastic connection, for example at the top of a door with two leaves of low height, the single control can act on a vertical transmission means capable of actuating at the bottom of the door a locking allowing limited opening.

Le mouvement d'ouverture ou de fermeture de chaque vantail peut être un mouvement de pivotement en arc de cercle autour d'un axe vertical autour duquel pivote le levier d'actionnement du vantail. Cependant, selon une variante, chaque vantail peut être solidaire de deux bras de longueurs différentes pivotant dans un plan horizontal autour d'axes verticaux différents tandis que le levier de commande de ce vantail est alors relié par la liaison élastique à l'un de ces bras.The opening or closing movement of each leaf can be a pivoting movement in an arc around a vertical axis around which the leaf actuation lever pivots. However, according to a variant, each leaf can be secured to two arms of different lengths pivoting in a horizontal plane around different vertical axes while the control lever of this leaf is then connected by elastic connection to one of these arms.

On remarquera que l'invention peut s'appliquer, par le doublement des mécanismes d'actionnement, à deux portes opposées, chacune à deux vantaux. Les deux mécanismes d'actionnement peuvent alors être disposés symétriquement par rapport à un plan vertical de symétrie entre les deux portes. On dispose alors sur un même véhicule de deux passages d'accès et de sortie à travers la moitié des surfaces verticales de la carrosserie du véhicule.It will be noted that the invention can be applied, by doubling the actuation mechanisms, to two opposite doors, each with two leaves. The two actuation mechanisms can then be arranged symmetrically with respect to a vertical plane of symmetry between the two doors. There are then on the same vehicle two access and exit passages through half of the vertical surfaces of the vehicle body.

Pour bien faire comprendre l'invention, on en décrira ci-après à titre d'exemple une forme d'exécution préférée et quelques variantes en référence au dessin schématique annexé dans lequel: il

  • la figure 1 est une vue en coupe par un plan vertical entre les deux vantaux d'une porte de cabine avec manette de commande en haut de la porte et mécanismes d'actionnement en haut et en bas de cette porte représentée en position de fermeture;
  • la figure 2 est une coupe par un plan vertical perpendiculaire au plan de coupe de la figure 1 ;
  • la figure 3 est une coupe horizontale en position de fermeture;
  • la figure 4 est une vue de détail en plan à plus grande échelle montrant la liaison élastique entre un levier d'actionnement et un bras solidaire d'un vantail de la porte;
  • la figure 5 est une coupe analogue à celle de la figure 1 avec une commande de porte prévue seulement en haut de la porte mais transmettant son mouvement en fin de fermeture à un moyen de verrouillage en bas de porte au moyen d'une tige verticale de transmission;
  • la figure 6 est une coupe analogue à celle de la figure 2 mais correspondant à la figure 5;
  • la figure 7 est une coupe schématique horizontale; et
  • la figure 8 montre schématiquement en plan une variante selon laquelle chaque vantail, au lieu de pivoter d'un mouvement en arc de cercle autour d'un seul axe vertical, est solidaire de deux bras de longueurs différentes reliés aux bords verticaux opposés du vantail et pivotant autour d'axes verticaux différents.
To clearly understand the invention, a preferred embodiment and some variants will be described below by way of example with reference to the appended schematic drawing in which:
  • Figure 1 is a sectional view through a vertical plane between the two leaves of a cabin door with control lever at the top of the door and actuation mechanisms at the top and bottom of this door shown in the closed position;
  • Figure 2 is a section through a vertical plane perpendicular to the section plane of Figure 1;

  • Figure 4 is a detailed plan view on a larger scale showing the elastic connection between an actuating lever and an arm secured to a leaf of the door;
  • Figure 5 is a section similar to that of Figure 1 with a door control provided only at the top of the door but transmitting its movement at the end of closing to a locking means at the bottom of the door by means of a vertical rod transmission;
  • Figure 6 is a section similar to that of Figure 2 but corresponding to Figure 5;
  • Figure 7 is a schematic horizontal section; and
  • FIG. 8 schematically shows in plan a variant according to which each leaf, instead of pivoting in a circular arc movement around a single vertical axis, is secured to two arms of different lengths connected to the opposite vertical edges of the leaf and pivoting around different vertical axes.

Dans l'exemple d'exécution représenté aux figures 1 à 4, on a indiqué en 1 le châssis du véhicule muni d'une porte à deux vantaux 2 - 3. Une manette de commande 4 solidaire d'un levier 5 pivotant sur l'axe horizontal fixe 6 est muni, dans l'exemple représenté, d'un secteur denté 7 engrenant avec une crémaillère 8 portée par une pièce de commande 9 à déplacement horizontal rectiligne parallèlement au plan vertical de symétrie passant entre les deux vantaux. Cette pièce de commande porte une autre crémaillère 10 à dents verticales engrenant avec les dents d'un pignon horizontal 11 porté par l'extrémité supérieure d'un arbre de transmission vertical 12 qui porte à sa base un pignon horizontal 13 identique au pignon 11 et engrenant avec la crémaillère 14 d'une pièce de commande inférieure 15 identique à la pièce de commande supérieure 9 et entraînée d'un mouvement parallèle dans le même sens.In the embodiment shown in Figures 1 to 4, there is indicated at 1 the vehicle chassis with a door with two leaves 2 - 3. A control lever 4 secured to a lever 5 pivoting on the fixed horizontal axis 6 is provided, in the example shown, with a toothed sector 7 meshing with a rack 8 carried by a control piece 9 with rectilinear horizontal movement parallel to the vertical plane of symmetry passing between the two leaves. This control part carries another rack 10 with vertical teeth meshing with the teeth of a horizontal pinion 11 carried by the upper end of a vertical transmission shaft 12 which carries at its base a horizontal pinion 13 identical to the pinion 11 and meshing with the rack 14 of a lower control piece 15 identical to the upper control piece 9 and driven in a parallel movement in the same direction.

Les deux pièces de commande 9 et 15 entraînent les deux vantaux 2 - 3 respectivement en haut et en bas par des moyens identiques qu'on ne décrira ci-après que pour la commande des vantaux par le haut. Un maneton 16, solidaire de la pièce de commande 9 agit sur deux biellettes identiques 17 - 18 articulées à deux leviers symétriques 19 - 20 en rotation autour d'axes fixes verticaux 21 - 22 solidaires du châssis 1 et constituant les axes de rotation des deux vantaux 2 - 3. Le levier 19 est relié aux bras radiaux 23 - 24 solidaires du vantail 2 par une liaison élastique représentée à plus grande échelle sur la figure 4 et le levier 20 est relié de façon analogue aux bras radiaux 25 - 26 solidaires du vantail 3. Les bras 23 à 26 peuvent prendre appui, à leurs extrémités opposées aux axes fixes de pivotement 21 - 22, par l'intermédiaire de roulements 27 - 28 sur un chemin de roulement 29 solidaire du châssis et supportant ainsi le poids des deux vantaux 2 - 3. L'accouplement élastique représenté sur la figure 4 entre un levier 19 et les bras 23 - 24 est constitué d'une tige 30 solidaire du levier 19 et traversant le bras 23 dans un perçage avec jeu important pour permettre une certaine oscillation du bras 23 par rapport à cette tige 30. L'oscillation est limitée, dans l'exemple représenté, par un écrou 31 et contrôlée en sens inverse par la pression d'un ressort 32. Ce dispositif permet, d'une part, le réglage du positionnement des extrémités des bras 23 à 26 mais également une pression de contact entre les deux vantaux en position de fermeture. Ce dispositif élastique permet en outre de tolérer un certain entrebâillement des vantaux 2 - 3 sous l'effet d'un obstacle coincé entre ces vantaux sans nuire pour autant au verrouillage expliqué ci-après. On remarquera que l'écrou 31 pourrait être remplacé par un ressort permettant une oscillation des bras 23 à 26 dans les deux sens en position de fermeture verrouillée.The two control parts 9 and 15 drive the two leaves 2 - 3 respectively at the top and at the bottom by identical means which will only be described below for controlling the leaves from above. A crank pin 16, integral with the control piece 9 acts on two identical rods 17 - 18 articulated with two symmetrical levers 19 - 20 in rotation around fixed vertical axes 21 - 22 integral with the chassis 1 and constituting the axes of rotation of the two leaves 2 - 3. The lever 19 is connected to the radial arms 23 - 24 secured to the leaf 2 by an elastic connection shown on a larger scale in FIG. 4 and the lever 20 is similarly connected to the radial arms 25 - 26 secured to the leaf 3. The arms 23 to 26 can bear, at their ends opposite to the fixed pivot axes 21 - 22, by means of bearings 27 - 28 on a raceway 29 secured to the chassis and thus supporting the weight of the two leaves 2 - 3. The elastic coupling shown in FIG. 4 between a lever 19 and the arms 23 - 24 consists of a rod 30 secured to the lever 19 and passing through the arm 23 in a hole with large clearance to allow a certain o scillation of the arm 23 relative to this rod 30. The oscillation is limited, in the example shown, by a nut 31 and controlled in the opposite direction by the pressure of a spring 32. This device allows, on the one hand, adjusting the positioning of the ends of the arms 23 to 26 but also a contact pressure between the two leaves in the closed position. This elastic device also makes it possible to tolerate a certain cracking of the leaves 2 - 3 under the effect of an obstacle wedged between these leaves without detracting from the locking explained below. It will be noted that the nut 31 could be replaced by a spring allowing the arms 23 to 26 to oscillate in both directions in the locked closed position.

L'obtention du verrouillage résulte de la position des biellettes 17 - 18 qui forment une genouillère franchissant au voisinage de la fermeture une position de point mort correspondant à l'alignement des biellettes de telle sorte que, dans la position de fermeture l'application de forces parasites F exercées sur les vantaux dans le sens de l'ouverture se transmettent aux biellettes en tendant à les coincer davantage en position de verouillage. Malgré cet effet de verrouillage, les liaisons élastiques entre les leviers 19 - 20 et les bras 23 à 26 tolèrent un certain entrebâillement des vantaux.Obtaining the locking results from the position of the links 17 - 18 which form a toggle crossing in the vicinity of the closure a neutral position corresponding to the alignment of the links so that, in the closed position, the application of parasitic forces F exerted on the leaves in the opening direction are transmitted to the rods, tending to wedge them more in the locking position. Despite this locking effect, the elastic connections between the levers 19 - 20 and the arms 23 to 26 tolerate a certain cracking of the leaves.

Selon la variante schématisée aux figures 5 à 7, la commande des vantaux ne s'effectue que par leur extrémité supérieure sous l'action de la pièce de commande 9 sans utilisation d'une pièce de commande à la partie inférieure. On remarquera qu'on pourrait aussi n'utiliser qu'une commande des vantaux par le bas sans commande par le haut.According to the variant shown diagrammatically in FIGS. 5 to 7, the control of the leaves is only carried out by their upper end under the action of the control piece 9 without the use of a control piece at the bottom. It will be noted that one could also use only a control of the leaves from the bottom without control from the top.

Dans le cas d'une commande des vantaux par une seule des extrémités de leur hauteur, on peut prévoir à l'autre extrémité, à la place de la commande d'ouverture et de fermeture, un dispositif de verrouillage en position de fermeture. A cet effet, selon l'exemple d'exécution des figures 5 à 7, une came 33 fixée sur la pièce de commande 9 abaisse en position de fermeture la tige verticale 34 rappelée vers le haut par un ressort inférieur 35 agissant sur un levier de verrouillage 36 qui s'articule par l'une de ses extrémités à la base de la tige 34. Ce levier 36 pivote entre ses extrémités en 37 sur un axe fixe horizontal solidaire du châssis tandis que son extrémité opposée à la tige 34 présente la forme d'un T dont la traverse se termine par deux crochets destinés, en position d'abaissement de la tige 34, à retenir en position de verrouillage des butées des deux vantaux en laissant à ces vantaux la possibilité d'un entrebâillement limité.In the case of a control of the leaves by only one of the ends of their height, one can provide at the other end, in place of the opening and closing control, a locking device in the closed position. To this end, according to the exemplary embodiment of FIGS. 5 to 7, a cam 33 fixed to the control part 9 lowers in the closed position the vertical rod 34 biased upwards by a lower spring 35 acting on a lever. lock 36 which is articulated by one of its ends at the base of the rod 34. This lever 36 pivots between its ends at 37 on a horizontal fixed axis secured to the chassis while its end opposite the rod 34 has the form a T whose crosspiece ends with two hooks intended, in the lowering position of the rod 34, to retain in the locking position of the stops of the two leaves, leaving these leaves the possibility of limited opening.

Selon les deux exemples d'exécution représentés aux figures 1 à 4 et 5 à 7, chacun des deux vantaux d'une porte de cabine pivote autour d'un axe vertical en un mouvement en arc de cercle dans un plan horizontal. Il serait cependant possible, notamment dans le cas de portes de hauteur réduite, d'utiliser selon la figure 8 deux vantaux symétriques 39 - 40 dont les bords latéraux 41 - 42 et 43 - 44 pivotent autour d'axes verticaux différents sur lesquels s'articulent des bras de rotation de longueurs différentes. Un exemple de tels vantaux est représenté schématiquement par la vue en plan de la figure 8 sur laquelle on a indiqué en 41 - 42 les bords latéraux des deux vantaux 39 - 40 situés l'un contre l'autre en position de fermeture et en 43 - 44 les bords opposés. Les bras de rotation aboutissant aux bords 41 à 44 sont indiqués de 45 à 48 respectivement et les axes de rotation de 49 à 52. On a indiqué en trait interrompu les traces horizontales des extrémités des bras et en 41' à 44' les positions des bords des vantaux quand ces vantaux ont été amenés en position d'ouverture, tandis que la figure 8 les représente schématiquement en position de fermeture.According to the two embodiments shown in Figures 1 to 4 and 5 to 7, each of the two leaves of a cabin door pivots around a vertical axis in a circular arc movement in a horizontal plane. However, it would be possible, in particular in the case of doors of reduced height, to use, according to FIG. 8, two symmetrical leaves 39 - 40 whose lateral edges 41 - 42 and 43 - 44 pivot around different vertical axes on which s articulate rotation arms of different lengths. An example of such leaves is shown diagrammatically by the plan view of FIG. 8 in which the lateral edges of the two leaves 39 - 40 located one against the other in the closed position are indicated at 41 - 42 and at 43 - 44 opposite edges. The rotation arms leading to the edges 41 to 44 are indicated from 45 to 48 respectively and the axes of rotation from 49 to 52. The horizontal traces of the ends of the arms are shown in broken lines and in 41 'to 44' the positions of the edges of the leaves when these leaves have been brought into the open position, while FIG. 8 schematically shows them in the closed position.

On comprendra que les exemples d'exécution décrits ci-dessus n'ont aucun caractère limitatif et qu'on pourrait envisager diverses variantes sans s'écarter du cadre de l'invention définie par les revendications annexées.It will be understood that the embodiments described above have no limiting character and that various variants could be envisaged without departing from the scope of the invention defined by the appended claims.
