The engagement of the skiers on the conveyor belt 16 is controlled by the passage of the chair, which will take up these skiers, in front of a detector 22. Access to the conveyor belt 16 is controlled by a gate 20, managed by the detector 22, fastened to the entry pilon (pole, support) of the station. <IMAGE>

Description

L'invention est relative à un dispositif d'embarquement d'un télésiège ayant un câble à défilement continu, des attaches fixes de sièges au câble et une aire d'embarquement des passagers, qui s'étend dans la direction de défilement du câble, lequel dispositif comprend un tapis roulant entraîné à une vitesse inférieure à celle du câble pour déplacer les passagers, prêts à l'embarquement et debout sur le tapis, dans la direction de défilement du siège à une vitesse inférieure à celle du siège, lequel rattrape les passagers pour les prendre en charge et un cadenceur qui impose un engagement des passagers sur le tapis roulant en synchronisme avec le défilement des sièges pour assurer la prise en charge des passagers par le siège avant l'extrémité du tapis.The invention relates to a boarding device for a chairlift having a cable with continuous travel, fixed attachments of seats to the cable and a passenger loading area, which extends in the direction of travel of the cable, which device comprises a conveyor belt driven at a speed lower than that of the cable to move the passengers, ready for boarding and standing on the carpet, in the direction of travel of the seat at a speed lower than that of the seat, which catches up with the passengers to take care of them and a timer which imposes an engagement of the passengers on the treadmill in synchronism with the scrolling of the seats to ensure the care of the passengers by the seat before the end of the carpet.

L'embarquement sur les télésièges à attaches fixes est délicat et nécessite une certaine dextérité. Les sièges ne s'arrêtent pas dans les stations et ils cueillent en marche les passagers debout à l'emplacement d'embarquement. Le choc entre le siège et les passagers peut être brutal et en tous les cas gênant et cette difficulté d'embarquement limite la vitesse des télésièges et donc leur débit. Il a déjà été proposé de réduire la différence de vitesse entre le siège et les passagers, en déplaçant ces derniers dans la direction d'avancement des sièges, notamment par un tapis roulant disposé sur l'aire d'embarquement. A l'entrée du tapis est disposé un cadenceur, par exemple un portillon, qui synchronise la montée des passagers, en l'occurrence des skieurs sur le tapis, avec le déplacement des sièges afin d'éviter toute collision avec ceux-ci et la prise en charge des passagers avant la fin du tapis roulant. Le portillon s'ouvre, comme dans les télésièges classiques sans tapis roulant, automatiquement dès que le siège, destiné aux passagers précédents, est engagé sur l'aire d'embarquement devant le portillon, de façon à laisser aux passagers le temps d'atteindre l'emplacement d'embarquement. Un tel dispositif nécessite une équidistance des sièges, afin que la prise en charge des passagers par le siège intervienne toujours sensiblement au même emplacement. Cette équidistance est une contrainte lors du montage des attaches sur le câble et de leur décalage périodique et une variation accidentelle des distances n'est pas exclue. Dans un cas extrême les passagers arrivent au bout du tapis roulant avant d'avoir été rattrapés par le siège et l'accident est inévitable.Boarding on chairlifts with fixed fasteners is delicate and requires a certain dexterity. Seats do not stop at stations and pick up passengers standing at the boarding location on the move. The shock between the seat and the passengers can be brutal and in any case annoying and this difficulty in boarding limits the speed of the chairlifts and therefore their speed. It has already been proposed to reduce the speed difference between the seat and the passengers, by moving the latter in the direction of advancement of the seats, in particular by a conveyor belt arranged on the boarding area. At the entrance of the carpet is arranged a timer, for example a gate, which synchronizes the rise of the passengers, in this case skiers on the carpet, with the movement of the seats in order to avoid any collision with them and the care of passengers before the end of the treadmill. The gate opens, as in conventional chairlifts without a conveyor belt, automatically as soon as the seat, intended for the preceding passengers, is engaged on the boarding area in front of the gate, so as to leave the passengers time to reach the boarding location. Such a device requires an equidistance of the seats, so that the support of the passengers by the seat always intervenes substantially at the same location. This equidistance is a constraint during the mounting of the fasteners on the cable and their periodic offset and an accidental variation of the distances is not excluded. In an extreme case, the passengers reach the end of the treadmill before being caught by the seat and an accident is inevitable.

La présente invention a pour but de permettre la réalisation d'un dispositif d'embarquement à tapis roulant simple et parfaitement sûr.The present invention aims to allow the realization of a simple and perfectly safe conveyor belt boarding device.

Le dispositif d'embarquement selon l'invention est caractérisé en ce qu'il comporte un détecteur de passage d'un siège, disposé en un emplacement prédéterminé de la trajectoire des sièges bien avant le tapis roulant et commandant ledit cadenceur et que le passage d'un siège devant le détecteur commande le cadenceur pour un engagement sur le tapis roulant des passagers, devant prendre place sur ce siège, de façon que le siège prenne en charge ces passagers en un emplacement donné du tapis roulant.The boarding device according to the invention is characterized in that it comprises a detector for the passage of a seat, arranged in a predetermined location in the trajectory of the seats well before the treadmill and controlling said timer and that the passage of 'A seat in front of the detector controls the timer for engagement on the passenger treadmill, to take place on this seat, so that the seat supports these passengers at a given location on the treadmill.

La durée entre le passage du siège devant le détecteur et son arrivée à l'emplacement de prise en charge est parfaitement déterminée, ainsi que celle entre l'engagement des passagers sur le tapis roulant et leur arrivée à l'emplacement de prise en charge, laquelle prise en charge s'effectue donc toujours au même endroit du tapis. Ces durées sont indépendantes de l'espacement des sièges et il est donc inutile de prévoir une marge de sécurité additionnelle, en l'occurrence une plus grande longueur du tapis roulant. Elles dépendent par contre de la vitesse du câble et de la vitesse du tapis roulant, cette dernière étant avantageusement adaptée à celle du câble. A cet effet le dispositif d'embarquement est de préférence équipé d'une unité centrale, reliée au détecteur de passage, au cadenceur, au moteur du tapis roulant et à un capteur de vitesse du câble. L'unité centrale règle la vitesse du tapis roulant, par exemple entre un tiers et la moitié de celle du câble et elle comprend un temporisateur de réglage du décalage entre le détecteur et le cadenceur.The time between the passage of the seat in front of the detector and its arrival at the pick-up location is perfectly determined, as well as that between the engagement of passengers on the treadmill and their arrival at the pick-up location, which support is therefore always carried out in the same place on the mat. These times are independent of the seat spacing and it is therefore unnecessary to provide an additional safety margin, in this case a longer length of the treadmill. They depend on the other hand on the speed of the cable and the speed of the treadmill, the latter being advantageously adapted to that of the cable. For this purpose the boarding device is preferably equipped with a central unit, connected to the passage detector, to the timer, to the motor of the treadmill and to a sensor for cable speed. The central unit regulates the speed of the treadmill, for example between one third and half that of the cable and it includes a timer for adjusting the offset between the detector and the timer.

Selon un développement de l'invention le détecteur de passage est porté par le pylône d'entrée de la station, ce qui facilite sa fixation et sa connexion à l'unité centrale. Le décalage correspondant est bien entendu compensé par le temporisateur, lequel permet d'autres réglages manuels ou automatiques, notamment en fonction des variations de longueur et de la vitesse de défilement du câble.According to a development of the invention, the passage detector is carried by the entrance pylon of the station, which facilitates its fixing and its connection to the central unit. The corresponding offset is of course compensated for by the timer, which allows other manual or automatic adjustments, in particular as a function of variations in length and the speed of travel of the cable.

Le cadenceur est de préférence un portillon barrant l'accès au tapis roulant et dont l'ouverture est commandée par l'unité centrale. Le tapis roulant peut être précédé d'une courte piste fixe de lancement pour faciliter la montée des skieurs sur le tapis roulant, auquel cas le portillon est disposé à l'entrée de cette piste de lancement. La fermeture du portillon est commandée par un temporisateur empêchant tout engagement tardif sur le tapis roulant et/ou par un détecteur d'arrivée du siège qui constitue une sécurité additionnelle évitant toute collision entre les passagers et les sièges.The timer is preferably a gate blocking access to the treadmill and the opening of which is controlled by the central unit. The treadmill can be preceded by a short fixed launch track to facilitate the ascent of skiers on the treadmill, in which case the gate is located at the entrance to this launch track. The gate is closed by a timer preventing any late engagement on the treadmill and / or by a seat arrival detector which constitutes additional security avoiding any collision between the passengers and the seats.

L'invention est décrite par la suite dans son application préférentielle à un tapis roulant à défilement continu constant, mais il est clair que ce tapis peut être du type à vitesse variable pour une accélération des passagers. Le tapis roulant peut également être remplacé par d'autres systèmes de déplacement des passagers, par exemple des poussoirs ou des rouleaux rotatifs.The invention is described below in its preferred application to a treadmill with constant continuous movement, but it is clear that this treadmill can be of the variable speed type for acceleration of the passengers. The treadmill can also be replaced by other passenger movement systems, for example pushers or rotating rollers.

D'autres avantages et caractéristiques ressortiront plus clairement de la description qui va suivre d'un mode de mise en oeuvre de l'invention donné à titre d'exemple non limitatif et représenté au dessin annexé, dans lequel la figure unique est une vue schématique en plan d'un dispositif d'embarquement selon l'invention.Other advantages and characteristics will emerge more clearly from the description which follows of an embodiment of the invention given by way of nonlimiting example and represented in the appended drawing, in which the single figure is a schematic view. in plan of a boarding device according to the invention.

Sur la figure un câble 10, à défilement continu, s'étend entre deux stations, dont seule la station d'embarquement est représentée, en passant dans chaque station sur une poulie de renvoi 25, dont l'une est motrice. Des sièges 11, notamment à quatre places, sont fixés par des attaches fixes 12 au câble 10 à espacement régulier et dans la station d'embarquement ils défilent, à la sortie de la poulie, sur une aire d'embarquement 13 où ils cueillent au passage et en marche des passagers, en l'occurrence des skieurs 14. L'embarquement s'effectue sous la poulie, d'une manière bien connue des spécialistes, les skieurs 14 s'avançant droit dans l'axe du câble 10 de sortie vers l'emplacement d'embarquement 15. De tels télésièges sont bien connus et il est inutile de les décrire plus en détail.In the figure a cable 10, with continuous travel, extends between two stations, of which only the boarding station is shown, passing through each station on a return pulley 25, one of which is powered. Seats 11, in particular four seats, are fixed by fixed fasteners 12 to the cable 10 with regular spacing and in the boarding station they pass, at the exit of the pulley, on a boarding area 13 where they pick at passage and movement of passengers, in this case skiers 14. Boarding takes place under the pulley, in a manner well known to specialists, skiers 14 advancing straight along the axis of the output cable 10 to the boarding location 15. Such chairlifts are well known and need not be described in more detail.

L'aire d'embarquement 13 est équipée d'un tapis roulant 16, constitué d'une bande souple tendue entre deux tambours d'extrémité 17 à axes horizontaux parallèles portés par des paliers 18. L'un des tambours est entraîné en rotation par un moteur 19 et la largeur du tapis roulant 16 est adaptée à celle des sièges 11. A l'entrée du tapis roulant 16 et à l'extérieur du gabarit de passage des sièges, est disposé un cadenceur, par exemple un portillon 20 ou un feu de signalisation, dont l'ouverture permet à un groupe de skieurs 14.2, en attente d'embarquement, de s'engager sur le tapis roulant 16, qui les déplace vers l'emplacement d'embarquement 15, à une vitesse prédéterminée inférieure à celle du câble 10. Le portillon 20 est actionné par un moteur 26 et la surface du tapis roulant 16 est légèrement glissante pour amortir le choc, lors de l'engagement des skieurs 14.2 sur le tapis 16. Ce choc peut également être amorti par une courte piste de lancement en pente, avant le tapis roulant 16, permettant aux skieurs 14.2 d'atteindre à l'extrémité de la piste une vitesse voisine de celle du tapis 16. Dans ce cas le portillon 20 est placé à l'entrée de la piste de lancement.The boarding area 13 is equipped with a conveyor belt 16, consisting of a flexible band stretched between two end drums 17 with parallel horizontal axes carried by bearings 18. One of the drums is rotated by a motor 19 and the width of the treadmill 16 is adapted to that of the seats 11. At the entrance to the treadmill 16 and outside the seat passage template, is arranged a timer, for example a gate 20 or a signaling light, the opening of which allows a group of skiers 14.2, awaiting boarding, to engage on the conveyor belt 16, which moves them to the boarding location 15, at a predetermined speed less than that of the cable 10. The gate 20 is actuated by a motor 26 and the surface of the treadmill 16 is slightly slippery to absorb the shock, when the skiers 14.2 engage on the carpet 16. This shock can also be absorbed by a short launch pad in p ente, before the treadmill 16, allowing the skiers 14.2 to reach at the end of the track a speed close to that of the mat 16. In this case the gate 20 is placed at the entrance to the launch track.

A l'entrée de la station est disposé un pylône 21 de guidage et de maintien du câble 10 et ce pylône 21 porte en regard du brin descendant du câble 10, à l'opposé de l'aire d'embarquement 13, un détecteur 22, qui émet un signal à chaque passage d'un siège 11. Le détecteur 22 est relié à une unité centrale 23, qui pilote le fonctionnement du télésiège ou tout au moins du dispositif d'embarquement à tapis roulant 16. L'unité centrale 23 reçoit de plus un signal de vitesse du câble 10, fourni par un capteur 24 coopérant avec la poulie de renvoi 25 ou tout autre élément moteur du câble 10. Le moteur 19 d'entraînement du tapis roulant 16 et le moteur 26 du portillon 20 sont commandés par l'unité centrale 23.At the entrance to the station is a pylon 21 for guiding and holding the cable 10 and this pylon 21 carries opposite the strand down from the cable 10, opposite the boarding area 13, a detector 22, which emits a signal each time a seat 11 passes. The detector 22 is connected to a central unit 23, which controls the operation from the chairlift or at least from the conveyor belt boarding device 16. The central unit 23 also receives a speed signal from the cable 10, supplied by a sensor 24 cooperating with the return pulley 25 or any other driving element of the cable 10. The motor 19 for driving the conveyor belt 16 and the motor 26 for the gate 20 are controlled by the central unit 23.

La structure du dispositif d'embarquement ressortira plus clairement de la description suivante de son fonctionnement:The structure of the boarding device will emerge more clearly from the following description of its operation:

A l'instant représenté sur la figure un groupe de skieurs 14.1, debout sur le tapis roulant 16, atteint l'emplacement d'embarquement 15 où il est rattrapé et pris en charge par un siège 11.1, qui est déplacé par le câble 10 à une vitesse supérieure à celle du tapis roulant 16 déplaçant les skieurs 14.1. La vitesse du tapis roulant 16 est commandée par l'unité centrale 23 de façon à varier avec celle du câble 10 et elle est par exemple toujours le tiers de celle du câble 10. Ce rapport peut également varier en fonction de la vitesse du câble 10. La différence de vitesse entre les skieurs 14.1 et le siège 11.1 est relativement faible et le choc de prise en charge est ainsi notablement réduit.At the instant shown in the figure a group of skiers 14.1, standing on the conveyor belt 16, reaches the boarding location 15 where it is caught up and supported by a seat 11.1, which is moved by the cable 10 to a speed higher than that of the treadmill 16 moving the skiers 14.1. The speed of the treadmill 16 is controlled by the central unit 23 so as to vary with that of the cable 10 and it is for example always one third of that of the cable 10. This ratio can also vary as a function of the speed of the cable 10 The speed difference between the skiers 14.1 and the seat 11.1 is relatively small and the impact shock is thus considerably reduced.

Le siège suivant 11.2 vient de passer devant le détecteur 22, qui a envoyé un signal à l'unité central 23, déclenchant l'ouverture du portillon 20. Les skieurs 14.2, en attente devant le portillon 20, s'engagent sur le tapis roulant 16, qui les déplace vers l'emplacement d'embarquement 15 où ils sont rattrapés par le siège 11.2 qui a donné le signal d'engagement sur le tapis roulant 16 à ces skieurs 14.2. Le tapis roulant 16 est sensiblement horizontal et les skieurs 14 restent immobiles sur le tapis 16. La durée entre le moment où les skieurs 14.2 montent sur le tapis roulant 16 et le moment où ils sont pris en charge par le siège 11.2 est uniquement fonction de la vitesse du tapis roulant 16 et de la distance entre l'emplacement d'embarquement 15 et l'entrée du tapis roulant 16. Cette durée est parfaitement définie et elle doit correspondre à celle mise par le siège 11.2 pour franchir la distance entre le détecteur de passage 22 et l'emplacement d'embarquement 15. Cette correspondance peut être réalisée par un positionnement approprié du détecteur 22, mais en pratique il est plus simple de prévoir un temporisateur 27, qui transmet à l'unité centrale 23 le signal de passage avec un retard réglable. Le temporisateur 27 est de préférence inclus à l'unité centrale 23 et il permet une fixation du détecteur 22 sur une partie fixe du télésiège, en l'occurrence sur un pylône 21. Il est à noter qu'un allongement du câble 10 nécessite un réglage de la temporisation pour conserver le synchronisme d'arrivée des skieurs 14 et du siège 11 à l'emplacement d'embarquement 15 et ce réglage peut être manuel ou de préférence réalisé automatiquement par l'unité centrale 23. De même lors d'un changement de vitesse du câble 10, la temporisation doit être adaptée par l'unité centrale 23 à cette nouvelle vitesse, afin de tenir compte du temps de réaction des passagers et/ou si le rapport des vitesses du câble 10 et du tapis roulant 16 n'est pas parfaitement constant .The next seat 11.2 has just passed in front of the detector 22, which has sent a signal to the central unit 23, triggering the opening of the gate 20. The skiers 14.2, waiting in front of the gate 20, engage on the treadmill 16, which moves them to the boarding location 15 where they are caught by the seat 11.2 which has given the signal for engagement on the treadmill 16 to these skiers 14.2. The treadmill 16 is substantially horizontal and the skiers 14 remain stationary on the treadmill 16. The time between the moment when the skiers 14.2 get on the treadmill 16 and the moment when they are supported by the seat 11.2 is solely a function of the speed of the treadmill 16 and the distance between the loading location 15 and the entrance to the treadmill 16. This duration is perfectly defined and must correspond to that taken by the seat 11.2 to cross the distance between the passage 22 and the boarding location 15. This correspondence can be achieved by appropriate positioning of the detector 22, but in practice it is simpler to provide a timer 27, which transmits to the central unit 23 the passage signal with an adjustable delay. The timer 27 is preferably included in the central unit 23 and it allows the detector 22 to be fixed on a fixed part of the chairlift, in this case on a pylon 21. It should be noted that an extension of the cable 10 requires a adjustment of the time delay to keep the synchronism of arrival of the skiers 14 and of the seat 11 at the boarding location 15 and this adjustment can be manual or preferably carried out automatically by the central unit 23. Similarly during a cable 10 speed change, the time delay must be adapted by the central unit 23 to this new speed, in order to take into account the reaction time of the passengers and / or if the speed ratio of the cable 10 and the treadmill 16 n is not perfectly constant.

On voit que le cycle d'embarquement des skieurs 14 sur un siège 11 est déclenché par ce siège, lors du passage devant le détecteur 22 et que ce cycle est indépendant de l'espacement des sièges successifs. Seul un écartement minimal, permettant aux skieurs 14 d'accéder à l'emplacement d'embarquement 15 sans entrer en collision avec le siège précédent, doit être respecté et ce contrôle est réalisé par l'unité centrale 23 qui déclenche une alarme ou un arrêt de l'installation lors d'un risque de collision.We see that the boarding cycle of skiers 14 on a seat 11 is triggered by this seat, when passing in front of the detector 22 and that this cycle is independent of the spacing of the successive seats. Only a minimum spacing, allowing skiers 14 to access the boarding location 15 without colliding with the previous seat, must be respected and this control is carried out by the central unit 23 which triggers an alarm or a stop installation during a risk of collision.

L'engagement des skieurs 14 sur le tapis roulant 16 peut être facilité en prévoyant avant le tapis roulant 16 une piste descendante sur laquelle les skieurs glissent et prennent de la vitesse. Le portillon 20 est alors disposé à l'entrée de la piste et comme la vitesse de glissement des skieurs sur la piste n'est pas parfaitement définie, la position de l'emplacement d'embarquement 15 peut légèrement varier. La longueur du tapis roulant 16 doit alors tenir compte de ces variations. Le télésiège est équipé des sécurités usuelles évitant toute fausse manoeuvre, notamment au démarrage et à l'arrêt de l'installation.The engagement of skiers 14 on the treadmill 16 can be facilitated by providing before the treadmill 16 a descending track on which the skiers slide and gain speed. The gate 20 is then placed at the entrance to the track and, like the sliding speed of the skiers on the runway is not perfectly defined, the position of boarding location 15 may vary slightly. The length of the treadmill 16 must then take account of these variations. The chairlift is fitted with the usual safety devices to prevent any false maneuver, in particular when starting and stopping the installation.

L' invention est bien entendu nullement limitée au mode de mise en oeuvre plus particulièrement décrit en référence aux dessins et elle s' étend à toute variante restant dans le cadre des équivalences.The invention is of course in no way limited to the embodiment more particularly described with reference to the drawings and it extends to any variant remaining within the framework of equivalences.
