Description

L'invention est relative à un dispositif d'embarquement d'un télésiège ayant un câble à défilement continu, des attaches fixes des 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 disposé sur l'aire d'embarquement et 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 et les prend en charge, ledit tapis roulant ayant deux tambours à axe horizontal disposés aux deux extrémités du tapis et une bande souple sans fin, tendue et entraînée par les deux tambours.The invention relates to a boarding device for a chairlift having a cable with continuous travel, fixed attachments of the 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 arranged on the boarding area and 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 and supports them, said conveyor belt having two drums with horizontal axis arranged at the two ends of the belt and an endless flexible band, stretched and driven by the two drums.

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 le quai d'embarquement. Les gares des télésièges sont en général ouvertes ou comportent un abri sommaire, qui ne protège pas l'installation des intempéries et du froid et le tapis roulant est une cause additionnelle d'incidents techniques.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 platform. Chairlift stations are generally open or have a basic shelter, which does not protect the installation from bad weather and cold, and the conveyor belt is an additional cause of technical incidents.

La présente invention a pour but de permettre la réalisation d'un dispositif simple d'embarquement à tapis roulant, dont le bon fonctionnement n'est pas affecté par la neige ou la glace.The present invention aims to allow the realization of a simple boarding device with conveyor belt, the proper functioning of which is not affected by snow or ice.

Le dispositif d'embarquement selon l'invention est caractérisé en ce que au moins l'un desdits tambours est faiblement bombé en forme de tonneau pour centrer la bande sur le tambour dans l'axe du câble et que la surface externe du tambour présente des alvéoles pour l'évacuation de la neige ou de la glace venant s'insérer entre le tambour et la bande.The loading device according to the invention is characterized in that at least one of said drums is slightly curved in the shape of a barrel to center the strip on the drum in the axis of the cable and that the external surface of the drum has cells for the evacuation of snow or ice coming to be inserted between the drum and the band.

L'autocentrage de la bande évite tout guidage latéral susceptible d'être bloqué par la neige ou la glace et cet autocentrage est conservé même si la neige ou la glace, déposée sur la face interne de la bande, est entraînée entre le tambour et la bande. Cette neige est poussée par la force d'appui de la bande dans les alvéoles du tambour et elle ne modifie donc pas la forme externe du tambour. Tout risque de déviation latérale de la bande, due à une accumulation de neige ou de glace sur le tambour bombé, est ainsi exclu.The self-centering of the strip avoids any lateral guidance liable to be blocked by snow or ice and this self-centering is retained even if the snow or ice, deposited on the internal face of the strip, is entrained between the drum and the bandaged. This snow is pushed by the force of support of the strip in the cells of the drum and it therefore does not modify the external shape of the drum. Any risk of lateral deviation of the strip, due to an accumulation of snow or ice on the curved drum, is thus excluded.

Le tambour est avantageusement creux et le fond des alvéoles communique avec l'espace interne du tambour pour faciliter l'évacuation de la neige. Les alvéoles peuvent être constitués par des palettes radiales réparties sur le pourtour du tambour et confinant des rainures longitudinales. D'autres formes de réalisation du tambour sont concevables, notamment un tambour cylindrique sur lequel est emmanché un douille bombée ayant des alvéoles ou un tambour en forme de cage d'écureuil constitué de barres longitudinales espacées. Un simple grillage ou une tôle en métal déployé perforé peut être enroulée en cylindre bombé pour former un tambour de centrage selon l'invention.The drum is advantageously hollow and the bottom of the cells communicates with the internal space of the drum to facilitate the evacuation of the snow. The cells can be constituted by radial pallets distributed around the periphery of the drum and confining longitudinal grooves. Other embodiments of the drum are conceivable, in particular a cylindrical drum on which is fitted a domed sleeve having cells or a drum in the form of a squirrel cage made up of spaced apart longitudinal bars. A simple mesh or a sheet of perforated expanded metal can be wound into a curved cylinder to form a centering drum according to the invention.

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 aux dessins annexés, dans lesquels;

  • la figure 1 est une vue schématique en plan d'un dispositif d'embarquement selon l'invention;
  • la figure 2 est une vue en perspective d'un tambour du dispositif selon la figure 1;
  • la figure 3 est une coupe axiale du tambour selon la figure 2;
  • les figures 4, 5 et 6 sont des vues en perspective de variantes de réalisation de tambours.
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 drawings, in which;
  • Figure 1 is a schematic plan view of a boarding device according to the invention;
  • Figure 2 is a perspective view of a drum of the device according to Figure 1;
  • Figure 3 is an axial section of the drum according to Figure 2;
  • Figures 4, 5 and 6 are perspective views of alternative embodiments of drums.

La figure 1 correspond à la figure unique de la demande de brevet de la demanderesse, déposée conjointement et le lecteur se reportera avantageusement à cette demande pour de plus amples détails. Sur la figure 1 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.Figure 1 corresponds to the single figure of the applicant's patent application, filed jointly and the reader will advantageously refer to this application for further details. In Figure 1 a cable 10, continuously scrolled, 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, 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 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, 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 slope, before the treadmill 16, allowing skiers 14 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. Un temporisateur 27 est intercalé entre le détecteur 22 et le cadenceur 20.At the entrance to the station is a pylon 21 for guiding and holding the cable 10 and this pylon 21 carries, opposite the downward strand of 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 of the chairlift or at least of 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 motor element of the cable 10. The motor 19 for driving the treadmill 16 and the motor 26 for the gate 20 are controlled by the central unit 23. A timer 27 is inserted between the detector 22 and the timer 20.

En se référant plus particulièrement aux figures 2 et 3 on voit que le tambour cylindrique 17 ou éventuellement les deux tambours du tapis roulant 16, comporte une forme externe en tonneau faiblement bombée, qui assure le centrage du tapis roulant 16. Le pourtour externe du tambour 17 présente des alvéoles constitués par des rainures 28 qui s'étendent suivant les génératrices du tambour 17 sur toute la longueur de celui-ci. Les rainures 28 sont confinées par des palettes 29, réparties sur le pourtour du tambour 17 dans des plans diamétraux et dont les tranches externes bombées 30 constituent les faces d'appui du tapis 16. Les tranches internes des palettes 29 sont soudées à un corps cylindrique creux 31, dont les deux fonds 32 ajourés portent des tourillons 33, qui sont montés dans les paliers 18. Le pourtour du corps 31 peut également être ajouré pour permettre une évacuation de la neige vers l'intérieur du corps cylindrique 31. On comprend que la structure, selon l'invention, du tambour 17 empêche toute accumulation de neige sur le pourtour externe et que les palettes 29 peuvent être solidarisées par d'autres moyens, notamment par les deux fonds 32 et/ou des disques (non représentés) échelonnés le long de l'axe du cylindre.Referring more particularly to FIGS. 2 and 3, it can be seen that the cylindrical drum 17 or possibly the two drums of the conveyor belt 16, has an external shape in a slightly convex barrel, which ensures the centering of the conveyor belt 16. The external periphery of the drum 17 has cells formed by grooves 28 which extend along the generatrices of the drum 17 over the entire length of the latter. The grooves 28 are confined by pallets 29, distributed around the periphery of the drum 17 in diametrical planes and whose curved external edges 30 constitute the bearing faces of the mat 16. The internal edges of the pallets 29 are welded to a cylindrical body hollow 31, of which the two perforated bottoms 32 carry pins 33, which are mounted in the bearings 18. The periphery of the body 31 can also be perforated to allow evacuation of the snow towards the interior of the cylindrical body 31. It is understood that the structure, according to the invention, of the drum 17 prevents any accumulation of snow on the outer periphery and that the pallets 29 can be secured by other means, in particular by the two bottoms 32 and / or discs (not shown) staggered along the axis of the cylinder.

La figure 4 illustre une variante de réalisation du tambour 17, constitué de barres 34 disposées suivant les génératrices du tambour pour former une cage d'écureuil, dont les deux fonds (non représentés) portent les tourillons du tambour, de la manière décrite ci-dessus.FIG. 4 illustrates an alternative embodiment of the drum 17, consisting of bars 34 arranged along the generatrices of the drum to form a squirrel cage, the two bottoms of which (not shown) carry the trunnions of the drum, as described below. above.

Les figures 5 et 6 montrent deux autres variantes, comprenant l'une un grillage 35 et l'autre un métal déployé perforé 36 enroulé en cylindre bombé pour constituer le tambour 17. Les tourillons ou l'axe du cylindre sont fixés par tout moyen approprié. Il est également possible de réaliser le tambour en deux parties , l'une en forme de douille externe alvéolée et l'autre en forme de noyau sur lequel la douille est emmanchée.Figures 5 and 6 show two other variants, one comprising a mesh 35 and the other a perforated expanded metal 36 wound in a curved cylinder to form the drum 17. The pins or the axis of the cylinder are fixed by any suitable means . It is also possible to produce the drum in two parts, one in the form of an alveolate external sleeve and the other in the form of a core on which the sleeve is fitted.

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 revendications qui suivent.The invention is of course in no way limited to the mode of implementation more particularly described with reference to the drawings and it extends to any variant remaining within the scope of the claims which follow.
