PCT No. PCT/FR96/00413 Sec. 371 Date Sep. 4, 1997 Sec. 102(e) Date Sep. 4, 1997 PCT Filed Mar. 20, 1996 PCT Pub. No. WO96/29223 PCT Pub. Date Sep. 26, 1996A loading station of a detachable chair-lift comprises two spots 22, 29 for alternate pickup of skiers 21. To give the skiers easy access to the pickup spots, the distance between the chairs is increased by grouping them in pairs in the access zones. The station may comprise two tracks 16, 17, each having a pickup spot, onto which the chairs 11, uncoupled from the rope, are directed alternately. The two pickup spots can be on the same track, one after the other, the grouping of the chairs in pairs then being modified when running between the two pickup spots so that the rear chair of the pair at the first is pickup spot comes in front at the second pickup spot.

Description

L'invention est relative à un télésiège débrayable selon le préambule de la revendication 1.The invention relates to a detachable chairlift according to the preamble of claim 1.

L'invention est décrite par la suite dans son application préférentielle à un télésiège débrayable, et plus particulièrement à une station d'embarquement généralement située en aval, mais il est clair qu'elle est applicable à d'autres transporteurs, notamment à des télécabines.The invention is described below in its application preferable to a detachable chairlift, and more particularly at a boarding station usually located downstream, but it is clear that it is applicable to other carriers, including cable cars.

La capacité de transport est un facteur essentiel d'un télésiège et elle dépend du nombre de places de chaque siège et de la vitesse et de l'espacement en ligne des sièges. Le développement de télésièges débrayables a permis une augmentation de la vitesse en ligne et donc du débit, tout en disposant d'une facilité d'embarquement sur des sièges défilant à vitesse réduite. La vitesse des sièges dans les stations étant plus faible, ceux-ci sont plus rapprochés que sur la ligne, notamment dans la zone d'embarquement et à débit élevé le passage des skieurs entre les deux sièges rapprochés, pour accéder à l'emplacement d'embarquement, est d'autant plus difficile que la dimension des sièges, à deux, trois, quatre ou plus de places, est grande.Transport capacity is a key factor in chairlift and it depends on the number of seats in each seat and seat speed and line spacing. The development of detachable chairlifts has enabled increase in line speed and therefore speed, while with easy boarding on scrolling seats at reduced speed. The speed of seats in stations being weaker, these are closer together than on the line, especially in the boarding area and at high speed the passage of skiers between the two seats close together, to accessing the boarding location is all the more difficult as the size of the seats, two, three, four or more places, is great.

La présente invention a pour but de permettre la réalisation d'un télésiège à capacité de transport élevée et à embarquement en toute sécurité et ce but est atteint par la mise en oeuvre des caractéristiques de la revendication 1.The present invention aims to allow the realization a chairlift with high transport capacity and boarding safely and this goal is achieved by implementing of the features of claim 1.

Le document US-A-4,050,385 décrit un télésiège débrayable, dont la trajectoire de transfert des sièges est dédoublée en deux voies parallèles, ayant chacune un emplacement d'embarquement. Les sièges sont orientés alternativement sur l'une et sur l'autre voie, afin d'augmenter le débit de l'installation. Les deux voies se croisent et les emplacements d'embarquement sont disposés sur les sections externes des voies. Les skieurs sont assis perpendiculairement à la ligne et ils embarquent sur les sièges, à l'arrêt, par l'arrière, sans croiser la trajectoire des sièges ou l'une des voies. L'embarquement à l'arrêt réduit le débit du télésiège et, au croisement des deux voies, l'un des sièges est chargé et le moindre dérèglage peut provoquer un accident corporel.Document US-A-4,050,385 describes a detachable chairlift, of which the seat transfer path is split in two parallel lanes, each with a boarding location. The seats are oriented alternately on one and on the other way, in order to increase the flow of the installation. The two lanes intersect and the boarding locations are arranged on the outer sections of the tracks. Skiers are sit perpendicular to the line and they get on the seats, stationary, rear, without crossing path seats or one of the tracks. Boarding at a reduced stop the speed of the chairlift and, at the crossing of the two tracks, one seats are loaded and the slightest adjustment can cause body accident.

Le document EP-A- 0 306 771 décrit une voie de garage d'un télésiège débrayable, sur laquelle les sièges sont stockés à faible distance les uns des autres.The document EP-A- 0 306 771 describes a siding of a detachable chairlift, on which the seats are stored short distance from each other.

Le regroupement par paires des sièges, selon l'invention, augmente l'intervalle entre le siège arrière d'une paire et le siège avant de la paire suivante. Ce regroupement peut être piloté par un changeur de cadence, disposé à l'entrée de la station, pour modifier la vitesse de décélération des sièges après leur désaccouplement du câble. Le changeur de cadence peut également être disposé dans la station amont, de façon à regrouper les sièges par paires dès la sortie de cette station, la répartition inégale des sièges le long de la ligne n'étant pas gênante, puisque ces sièges sont vides.The grouping by pairs of seats, according to the invention, increases the interval between the rear seat of a pair and the front seat of the next pair. This grouping can be controlled by a cadence changer, located at the entrance to the station, to change the deceleration speed of the seats after uncoupling the cable. The Cadence Changer can also be placed in the upper station, so that group the seats in pairs as soon as you leave this station, the unequal distribution of seats along the line not being not embarrassing, since these seats are empty.

Selon un premier mode de mise en oeuvre de l'invention la trajectoire de transfert est dédoublée par une bifurcation en une voie intérieure et une voie extérieure, ayant chacune un emplacement d'embarquement avec une piste d'accès. Un dispositif d'aiguillage oriente alternativement les sièges sur l'une et sur l'autre voie et la fréquence de passage des sièges à un emplacement d'embarquement est ainsi divisée par deux, de façon à faciliter l'embarquement. Il est d'ailleurs concevable de prévoir trois ou un nombre supérieur de voies pour réduire encore cette fréquence. L'accès à l'emplacement d'embarquement de la voie extérieure ne pose aucune difficulté. La voie intérieure est par contre entourée par la voie extérieure et la piste d'accès à l'emplacement d'embarquement de la voie intérieure croise obligatoirement une voie. En regroupant par paires les sièges, selon l'invention, on augmente l'intervalle avec le siège suivant et on facilite le passage des skieurs entre les paires de sièges vers l'emplacement d'embarquement. Le risque de collision entre un siège et un skieur, avançant sur la piste d'accès, est ainsi notablement réduit et quasi équivalent à celui des télésièges conventionnels, puisque les deux sièges d'une paire traversent en même temps le croisement. La zone de croisement de la piste d'accès et des voies coincide avantageusement avec la zone de bifurcation des voies.According to a first embodiment of the invention the transfer trajectory is split by a bifurcation in an inner and an outer track, each having a boarding location with an access runway. A switching device alternately orients the seats on both lanes and the frequency of the seats at a boarding location is thus halved, by to facilitate boarding. It is also conceivable provide three or more channels to reduce again this frequency. Access to the boarding location from the outside way poses no difficulty. The way interior is however surrounded by the exterior route and the access track to the boarding location interior must cross a path. By grouping by pairs the seats according to the invention, the interval is increased with the next seat and it facilitates the passage of skiers between pairs of seats to the boarding location. The risk of collision between a seat and a skier, advancing on the access road, is thus significantly reduced and almost equivalent to that of chairlifts conventional, since the two seats of a pair cross at the same time crossing. The runway crossing area of access and tracks advantageously coincides with the area of bifurcation of the tracks.

Selon un développement de l'invention les emplacements d'embarquement sont disposés de façon que les pistes d'accès à ces emplacements sont tangentes à une courbe de la voie et la voie intérieure, en forme de demi-boucle, s'étend dans l'axe de la ligne, de la manière usuelle. L'emplacement d'embarquement de la voie intérieure est adjacent à la zone de croisement de la piste d'accès et des voies. Un portillon, disposé sur la piste d'accès, pilote avantageusement l'engagement des skieurs sur cette piste d'accès.According to a development of the invention the locations boarding lanes are arranged so that the access routes to these locations are tangent to a curve of the track and the inner track, in the form of a half-loop, extends in the axis of the line, in the usual way. The boarding location of the inner lane is adjacent to the crossing area of the access track and tracks. A gate, placed on the access track, advantageously controls the engagement of skiers on this access track.

Selon une variante de réalisation de l'invention, les deux voies sont, dans la zone de croisement, toutes deux incurvées en direction de l'emplacement d'embarquement et le siège en avant, vu dans le sens de déplacement, dans la paire de sièges est orienté dans la bifurcation sur la voie intérieure Cette incurvation des voies permet un dégagement rapide de la zone de croisement par les sièges. Le siège en avant suit la trajectoire la plus incurvée et il aborde donc un skieur en retard par l'arrière, sans grand risque d'accident.According to an alternative embodiment of the invention, the two tracks are, in the crossing zone, both curved towards the boarding location and the seat in front, seen in the direction of travel, in the pair of seats is oriented in the bifurcation on the inner track This curve of the tracks allows rapid clearance of the crossing by the seats. The forward seat follows the most curved trajectory and so he approaches a skier in delay from behind, without great risk of accident.

Selon une autre variante de réalisation, la voie intérieure et la voie extérieure, chacune en forme de demi-boucle, sont disposées dans l'axe de la ligne, en étant décalées le long de cet axe. Dans ce cas le siège en avant est de préférence orienté dans la bifurcation sur la voie extérieure. Ce siège en avant croise perpendiculairement la piste d'accès, tandis que le siège de derrière oblique sur la voie intérieure en dégageant rapidement la zone de croisement.According to another alternative embodiment, the internal route and the outer track, each in the form of a half-loop, are arranged in the axis of the line, being offset along this axis. In this case the front seat is preferably oriented in the bifurcation on the outside track. This seat in front crosses the access track perpendicularly, while the back seat oblique on the inside track in quickly clearing the crossing area.

L'agencement des deux voies et leur trajectoire peuvent être différents et être déterminés par le site ou la structure de la station, mais les deux voies ne se croisent jamais, pour éviter tout risque de collision entre les sièges et des dispositifs compliqués de synchronisation. Les longueurs des voies et les vitesses de déplacement des sièges sur ces voies sont telles que les sièges ont à la sortie des voies la même cadence qu'à l'entrée, avec éventuellement un décalage de l'ordre des sièges.The arrangement of the two tracks and their trajectory can be different and be determined by the site or the structure of the station, but the two ways never cross, to avoid any risk of collision between seats and devices complicated synchronization. Track lengths and seat travel speeds on these tracks are such that the seats have the same cadence as at the end of the tracks the entry, with a possible shift of the order of seats.

Il est à noter que la station d'embarquement peut facilement être agencée pour un débarquement de skieurs, en prévoyant sur chacune des voies, avant l'emplacement d'embarquement, un emplacement de débarquement.Note that the boarding station can easily be arranged for a landing of skiers, by planning on each lane, before the embarkation location, a landing location.

Selon un autre mode de mise en oeuvre de l'invention, les deux emplacements d'embarquement sont disposés l'un après l'autre sur une même voie. Les sièges sont regroupés par paires une première fois pour le passage du premier emplacement d'embarquement et une deuxième fois pour le passage du deuxième emplacement d'embarquement, avec une permutation des sièges regroupés, de façon que le siège, qui était en avant de la paire à l'entrée du premier emplacement d'embarquement et qui a embarqué des skieurs à ce premier emplacement, est à l'arrière de la paire à l'entrée du deuxième emplacement d'embarquement. Les emplacements d'embarquement sont disposés dans une courbe de la voie, de façon que les pistes d'accès à ces emplacements sont tangentes à la courbe et ces deux emplacements d'embarquement sont sensiblement à angle droit. Des portillons, synchronisés avec le défilement des sièges, commandent l'engagement des skieurs SUT les pistes d'accès.According to another embodiment of the invention, the two boarding spaces are arranged one after the other on the same track. The seats are grouped in pairs one first time for the passage from the first location boarding and a second time for the passage of the second boarding location, with seat swapping grouped together, so that the seat, which was in front of the pair at the entrance to the first boarding location and which has onboard skiers at this first location, is at the back of the pair at the entrance to the second boarding location. Boarding locations are arranged in a curve of the track, so that the access tracks to these locations are tangent to the curve and these two locations boarding passes are substantially at right angles. Gates, synchronized with the scrolling of the seats, control the commitment of the SUT skiers to the access tracks.

Le débarquement à l'arrivée est moins critique que l'embarquement et il peut souvent être réalisé, de la manière usuelle, avec une simple pente. Il est néanmoins possible d'utiliser un système à deux voies, ayant chacune un emplacement de débarquement, analogue au dispositif d'embarquement. Une version simplifiée, selon l'invention, comporte une trajectoire de transfert dédoublée en deux voies parallèles, dont chacune présente un emplacement de débarquement en forme de rampe. Un dispositif d'aiguillage oriente alternativement les sièges sur l'une et sur l'autre voie et les deux rampes sont en pente pour permettre le dégagement des skieurs en passant normalement sous les sièges et la voie. Tout risque de collision avec un siège est donc exclu.Disembarking on arrival is less critical than boarding and it can often be done, in the way usual, with a simple slope. It is nevertheless possible to use a two-way system, each having a landing location, similar to the device boarding. A simplified version, according to the invention, has a transfer path split into two lanes parallel, each of which has a location of landing in the form of a ramp. A referral device alternately orient the seats on one and on the other track and the two ramps are sloping to allow the clearance for skiers normally passing under the seats and the way. Any risk of collision with a seat is therefore excluded.

    • Sur les figures 1-6 une station d'embarquement d'un télésiège débrayable, comporte à l'entrée de la station une zone 10 de débrayage des sièges 11 d'un câble 12 et de décélération de ces sièges, lesquels roulent sur un rail 13 pour être transférés vers la sortie de la station où ils sont réaccélérés sur une zone d'accélération 14 avant d'être réaccouplés au brin opposé du câble 12. L'entraínement et la décélération des sièges 11 désaccouplés du câble 12 est réalisé par tout moyen approprié, par exemple par des chaínes à taquets ou des trains de roues a pneumatique 33. De tels télésièges débrayables, à embarquement à vitesse réduite, sont bien connus et il est inutile de les décrire plus en détail.In Figures 1-6 a chairlift boarding station disengageable, includes at the entrance of the station a zone 10 of declutching the seats 11 of a cable 12 and decelerating them seats, which roll on a rail 13 to be transferred towards the exit of the station where they are re-accelerated on a acceleration zone 14 before being re-coupled to the opposite strand of the cable 12. The driving and deceleration of the seats 11 uncoupled from the cable 12 is produced by any suitable means, for example by cleats or sets of wheels has pneumatic 33. Such detachable chairlifts, on board at low speed are well known and need not be describe in more detail.

    Selon l'invention un aiguillage 15, disposé après la zone de décélération 10, permet d'orienter sélectivement les sièges 11 sur une voie intérieure 16 ou sur une voie extérieure 17. Les deux voies 16,17 sont raccordées par un aiguillage 18 à la zone d'accélération 14 et la voie extérieure 17 entoure la voie intérieure 16. La trajectoire de transfert des sièges 11, d'un brin du câble 12 vers le brin opposé, est ainsi dédoublée par les deux voies 16,17, qui comportent chacune un rail 13 et des moyens de propulsion associés. La voie intérieure 16 est en forme de demi-boucle, disposée dans l'axe de la ligne de la manière usuelle. Elle comporte une partie courbe 20 sur laquelle est prévu un emplacement d'embarquement 22, avec une piste d'accès 23, dont l'axe est sensiblement tangent à la courbe 20. Les sièges 11 sont à six places, mais ce nombre peut être différent et la piste d'accès 23, à six portillons 24, permet un déplacement de front de six skieurs 21, représentés sur les figures par des triangles, vers l'emplacement d'embarquement 22. La voie extérieure 17 est une demi-boucle déformée avec un décalage latéral, de façon à suivre au début la courbure de la voie intérieure 16 et présenter une première partie 19 incurvée dans la même direction que la voie intérieure 16 en direction de l'emplacement d'embarquement 22. A cette première partie 19 succède une partie courbe 27 ayant, sensiblement au milieu, un emplacement d'embarquement 29, avec une piste d'accès 30, dont l'axe est tangent à la courbe 27. La piste d'accès 30, à six portillons 24, permet un déplacement de six skieurs 21 de front vers l'emplacement d'embarquement 29. Les deux pistes d'accès 23 et 30 sont parallèles et côte à côte, la piste 30 de la voie extérieure 17 accédant directement à l'emplacement d'embarquement, de la manière usuelle par l'arrière, tandis que la piste 23 de la voie intérieure 16 croise la voie extérieure 17, la zone de croisement 25 coïncidant avec la zone de bifurcation à aiguillage 15. L'emplacement d'embarquement 22 de la voie intérieure 16 est adjacent à la zone de croisement 25 et les portillons 24 sont disposés juste avant cette zone de croisement 25. On limite ainsi au maximum la distance à franchir par les skieurs 21 entre les portillons 24 et l'emplacement d'embarquement 22. Les mêmes portillons 24 commandent le franchissement du croisement 25 et l'accès à l'emplacement d'embarquement 22. Les portillons 24 sont disposés en oblique sur la piste pour épouser à peu près la courbure des voies 16,17 et leur ouverture peut être progressive, au fur et à mesure du passage du siège 11.According to the invention a switch 15, disposed after the area of deceleration 10, allows to selectively orient the seats 11 on an inner track 16 or on an outer track 17. The two channels 16,17 are connected by a switch 18 to the area acceleration 14 and the outer track 17 surrounds the track interior 16. The transfer trajectory of the seats 11, from a strand of cable 12 to the opposite strand, is thus split by the two tracks 16,17, which each have a rail 13 and associated means of propulsion. Inner track 16 is in shape of half-loop, arranged in the axis of the line of the usual way. It has a curved part 20 on which is provided with a boarding location 22, with a access track 23, the axis of which is substantially tangent to the curve 20. Seats 11 have six seats, but this number can be different and the access track 23, with six gates 24, allows a front displacement of six skiers 21, represented in the figures by triangles, towards the location boarding area 22. The external route 17 is a half-loop distorted with a lateral offset, so as to follow at the start the curvature of the interior track 16 and present a first part 19 curved in the same direction as the track interior 16 towards boarding location 22. This first part 19 is followed by a curved part 27 having, substantially in the middle, a boarding location 29, with an access track 30, the axis of which is tangent to the curve 27. The access track 30, with six gates 24, allows movement of six skiers 21 from the front to boarding location 29. The two access tracks 23 and 30 are parallel and side by side coast, runway 30 of external route 17 directly accessing at the loading location, in the usual way by rear, while runway 23 of interior track 16 crosses the outer lane 17, the crossing zone 25 coinciding with the switch point bifurcation zone 15. The boarding location 22 of the inner lane 16 is adjacent to the crossing zone 25 and the gates 24 are arranged just before this crossing zone 25. We limit thus the maximum distance to be crossed by skiers 21 between the gates 24 and the boarding location 22. The same gates 24 command crossing the crossing 25 and access to the boarding location 22. The gates 24 are arranged obliquely on the track to marry near the curvature of the tracks 16,17 and their opening can be progressive, as the seat passes 11.

    Selon un premier mode de mise en oeuvre de l'invention, le dispositif de décélération 33 des sièges 11 est agencé pour décadencer les sièges 11 et les rapprocher deux par deux, pour constituer des paires de sièges rapprochés, qui franchissent ensemble la zone de croisement 25. Le rapprochement peut être réalisé soit par l'arrêt d'un siège 11 à l'entrée de la zone de croisement 25 pour attendre le siège suivant, soit de préférence par modulation des décélérations, de façon que les deux sièges 11 se présentent ensemble à l'entrée de la zone de croisement 25 et franchissent celle-ci en même temps. Il est clair que l'écartement entre les paires de sièges 11 est augmenté et que les skieurs peuvent passer plus facilement entre les paires de sièges pour accéder à l'emplacement d'embarquement 22. Selon une variante de réalisation, le décadencement est réalisé dans la station amont, les sièges vides étant déjà regroupés par paires sur la ligne, de manière à simplifier la station aval d'embarquement.According to a first embodiment of the invention, the deceleration device 33 for seats 11 is arranged for decadent the seats 11 and bring them together two by two, to form pairs of close seats, which cross together the crossing zone 25. The approximation can be achieved either by stopping a seat 11 at the entrance to the crossing 25 to wait for the next seat, either preferably by modulating the decelerations, so that the two seats 11 are presented together at the entrance to the crossing 25 and cross it at the same time. It is clear that the spacing between the pairs of seats 11 is increased and that skiers can pass more easily between the pairs of seats to access the site boarding 22. According to an alternative embodiment, the decentering is carried out in the upstream station, the seats voids are already grouped in pairs on the line, so to simplify the downstream boarding station.

    La longueur de la voie extérieure 17 est plus grande que celle de la voie intérieure 16 et si les voies 16,17 sont parcourues à la même vitesse par les sièges 11, la différence de longueur doit être déterminée de façon à retrouver à la sortie la cadence régulière, avec un décalage de l'ordre des sièges, le siège de la voie intérieure 16 courte passant devant un ou deux sièges de la voie extérieure 17 longue. La cadence peut également être rétablie par des vitesses différentes des sièges 11 sur les voies 16,17 ou dans la zone 14 d'accélération .The length of the outer track 17 is greater than that of the inner track 16 and if the tracks 16,17 are crossed at the same speed by the seats 11, the difference in length must be determined so as to find at the exit the regular cadence, with a shift in the order of the seats, the interior track seat 16 short passing one or two seats on the outer track 17 long. Cadence can also be restored by different seat speeds 11 on tracks 16,17 or in acceleration zone 14.

    Le fonctionnement de l'installation ressort des figures 2 à 5. A l'instant représenté sur la figure 2, une paire de sièges 11,4 et 11.5, ont été ralentis et rapprochés sur la zone 10 de décélération, de façon à franchir à vitesse lente et ensemble la zone 25 de croisement et de bifurcation. Le premier siège 11.4 vient de franchir l'aiguillage 15, qui l'a orienté sur la voie intérieure 16 en direction de l'emplacement d'embarquement 22. Le deuxième siège 11.5 de la paire entre dans la zone de croisement 25 et va être orienté sur la voie extérieure 17. La piste d'accès 23 est fermée par les portillons 24, qui empêchent les skieurs 21 de s'engager sur la zone de croisement 25 et d'accéder à l'emplacement d'embarquement 22 de la voie intérieure 16. Le siège précédent 11.3 est sur la partie courbe 20 de la voie extérieure 17, à l'emplacement d'embarquement 29, tandis que le siège précédent 11.2, qui a suivi la voie intérieure 16 courte, est engagé sur la zone d'accélération 14 et a dépassé le premier siège 11.1, qui a parcouru la voie longue 17. On voit que le siège 11.6, qui suit la paire de sièges 11.4,11.5, est notablement espacé de cette paire.The operation of the installation is shown in Figures 2 to 5. At the instant shown in FIG. 2, a pair of seats 11.4 and 11.5, were slowed down and brought closer to zone 10 of deceleration, so as to cross at slow speed and together the crossing and bifurcation zone 25. The first seat 11.4 has just crossed the switch 15, which oriented it on the interior route 16 towards the boarding location 22. The second seat 11.5 of the pair enters the area of crossing 25 and will be oriented on the outside track 17. The access track 23 is closed by the gates 24, which prevent skiers 21 from entering the crossing zone 25 and access boarding location 22 of the lane interior 16. The previous seat 11.3 is on the curved part 20 of the outer lane 17, at embarkation location 29, while the previous seat 11.2, which followed the path inner 16 short, is engaged on the acceleration zone 14 and passed the first seat 11.1, which traveled the way long 17. We see that seat 11.6, which follows the pair of seats 11.4,11.5, is notably spaced from this pair.

    A l'instant représenté à la figure 3 le siège 11.4 est à l'emplacement d'embarquement 22 et le siège 11.5 s'engage sur la voie extérieure 17. Les figures suivantes 4 et 5 illustrent la progression des différents sièges 11, qui sont orientés alternativement sur la voie intérieure 16 et la voie extérieure 17 par l'aiguillage 15, ainsi que l'ouverture des portillons 24. Il est inutile de décrire plus en détail ce fonctionnement.At the instant shown in FIG. 3, the seat 11.4 is at boarding location 22 and seat 11.5 commits to the outer track 17. The following figures 4 and 5 illustrate the progression of the various seats 11, which are oriented alternately on the inner track 16 and the outer track 17 by switch 15, as well as the opening of the gates 24. There is no need to describe this operation in more detail.

    La figure 6 illustre une autre disposition des voies 16,17, dans laquelle la voie extérieure 17 est une demi-boucle, disposée également dans l'axe et dans le prolongement de la ligne, en étant décalée par rapport à la demi-boucle de la voie intérieure 16. La piste d'accès 23 de la voie intérieure 16 est alors sensiblement perpendiculaire à la voie extérieure 17. Dans cette variante le siège 11.5, qui sera orienté sur la voie extérieure 17, est à l'avant dans la paire de sièges 11.5,11.6 et le siège 11.6 à l'arrière dégage rapidement la zone de croisement en bifurquant vers le côté sur la voie intérieure 16. Le fonctionnement est bien entendu identique à celui décrit ci-dessus en référence aux figures 2 à 5.FIG. 6 illustrates another arrangement of the channels 16, 17, in which the outer track 17 is a half-loop, also arranged in the axis and in the extension of the line, being offset from the track half-loop interior 16. Access track 23 of interior route 16 is then substantially perpendicular to the external track 17. In this variant the seat 11.5, which will be oriented on the track exterior 17, is at the front in the pair of seats 11.5,11.6 and the rear seat 11.6 quickly clears the area of crossing by forking to the side on the inner track 16. The operation is of course identical to that described above with reference to Figures 2 to 5.

    Il est clair que les pistes d'accès 23,30 et les emplacements d'embarquement 22,29 associés peuvent être disposés en toute autre partie des courbes 20,27, en fonction de la place disponible et de la structure de la station. Il est concevable de prévoir une troisième voie de dérivation pour augmenter l'espacement des sièges 11. Chaque voie 16,17 peut comporter un emplacement de débarquement, disposé avant l'emplacement d'embarquement 22,29, ces emplacements n'étant pas obligatoirement dans les courbes 20,27. It is clear that the access tracks 23.30 and the locations boarding 22.29 associates can be arranged in any other part of the curves 20.27, depending on the place available and station structure. It is conceivable to provide a third diversion route to increase seat spacing 11. Each channel 16,17 can include a landing location, arranged before the location boarding 22,29, these spaces not being obligatorily in the curves 20.27.

    La station d'arrivée peut être sensiblement identique à la station de départ avec des voies dédoublées. Selon le débit et la structure de l'installation une station standard à une seule voie peut être suffisante, puisque le débarquement est plus facile que l'embarquement. La figure 7 illustre une station de débarquement simplifiée, dans laquelle les sièges sont alternativement aiguillés sur deux voies adjacentes parallèles 32,34, ayant chacune une rampe de débarquement en pente 35,36, qui fait passer les skieurs sous les sièges 11 et les voies 32,34, de la manière indiquée par des flèches sur la figure, sans risque de collision.The arrival station can be substantially identical to the departure station with split tracks. Depending on the flow and the structure of the installation a standard station with a single way may be sufficient, since the landing is more easy than boarding. Figure 7 illustrates a simplified disembarkation, in which the seats are alternately steered on two adjacent parallel tracks 32.34, each having a sloping landing ramp 35.36, which puts skiers under seats 11 and lanes 32,34, as indicated by arrows in the figure, without risk of collision.

    Selon un autre mode de mise en oeuvre de l'invention, illustré par les figures 8 et 9, la station d'embarquement comporte une voie unique 13, en forme de demi-boucle prolongeant la ligne de la manière usuelle. Deux emplacements d'embarquement 37,39, avec leurs pistes d'accès 38,40, sont disposés dans la courbe de la voie, respectivement au milieu et à la sortie de la courbe, de façon que l'ensemble des sièges 11 passent successivement aux deux emplacements d'embarquement 37,39. Les deux emplacements 37,39 sont sensiblement perpendiculaires l'un par rapport à l'autre et les pistes d'accès 38,40, tangentes à la courbe, sont équipées de portillons 24, dont l'ouverture est synchronisée avec le défilement des sièges 11. De la manière décrite ci-dessus, les sièges 11 se présentent, à l'entrée de la courbe, regroupés par paires et ils sont déplacés ensemble vers le premier emplacement d'embarquement 37, où le siège en avant de la paire cueille les skieurs 21. On comprend qu'entre les deux emplacements d'embarquement 37,39 le regroupement des sièges 11 par paires doit être modifié pour que le siège en arrière de la paire au premier emplacement d'embarquement 37 se présente en avant au deuxième emplacement 39 pour embarquer les skieurs. Cette permutation est obtenue par ralentissement et/ou accélération des sièges successifs de façon à regrouper le siège encore vide avec le siège, qui le suit et à le séparer du siège qui le précédait. On comprend que les skieurs 21 disposent de plus de temps pour avancer sur les pistes d'accès 38,40 et se placer aux emplacements d'embarquement 37,39. Le fonctionnement ressort clairement des figures 8 et 9 qui représentent la position des sièges 11 à deux moments successifs. Sur la figure 8 une paire de sièges 11.4,11.5 arrivent à l'entrée de la courbe, prêts à croiser la piste d'accès 38 et à embarquer sur le siège avant 11.4 les skieurs en attente au premier emplacement d'embarquement 37. Le siège 11.3, qui était groupé au siège précédent 11.2 pour franchir le premier emplacement 37, s'est séparé de ce dernier siège 11.2, et il attend le siège suivant 11.4 pour croiser ensemble la piste d'accès 40 du deuxième emplacement 39, où il embarquera les skieurs, qui avancent vers ce deuxième emplacement 39. La figure 9 représente ce moment où la paire de sièges 11.4,11.5 ont franchi le premier emplacement 37 et rattrapé le siège précédent 11.3, lequel avance, regroupé avec le siège 11.4, vers le deuxième emplacement 39 en croisant la piste d'accès 40. Le siège 11.5, à l'arrière de la paire de sièges 11.4,11.5, a ralenti pour se séparer du siège 11.4 et attendre le siège suivant 11.6 de la paire suivante 11.6,11.7. Les sièges 11.1,11.2 qui sortent de la courbe ont embarqué l'un 11.1 des skieurs au deuxième emplacement 39 et l'autre 11.2 des skieurs au premier emplacement 37. Il est à noter que l'écartement entre les paires de sièges 11.4,11.5 et 11.6,11.7 est plus grand que l'écartement entre des sièges, qui seraient régulièrement espacés et que le passage des skieurs entre les paires de sièges est ainsi plus facile. Il est inutile de décrire plus en détail le fonctionnement, qui ressort clairement de l'examen des figures 8 et 9.According to another embodiment of the invention, illustrated in Figures 8 and 9, the boarding station has a single track 13, in the form of a half-loop extending the line of the usual way. Two boarding spaces 37.39, with their access tracks 38.40, are arranged in the curve of the track, respectively in the middle and at the exit of the curved, so that all of the seats 11 pass successively at the two boarding locations 37.39. The two locations 37.39 are substantially perpendicular one relative to each other and the access roads 38.40, tangent to the curve, are fitted with gates 24, the opening of which is synchronized with the scrolling of seats 11. In the way described above, the seats 11 are presented at the entrance to the curve, grouped in pairs and they are moved together towards the first boarding location 37, where the seat in before the pair picks the skiers 21. We understand that between the two boarding locations 37.39 the grouping of 11 seats in pairs must be changed so that the seat in rear of pair at first boarding location 37 present forward at the second location 39 to embark the skiers. This permutation is obtained by slowing down and / or acceleration of successive seats so as to regroup the seat still empty with the seat, which follows it and separate it from the seat which preceded it. We understand that skiers 21 have more time to advance on the access tracks 38.40 and stand at boarding locations 37.39. The operation is clear from Figures 8 and 9 which represent the position of seats 11 at two times successive. In figure 8 a pair of seats 11.4,11.5 arrive at the entrance to the curve, ready to cross the track access 38 and board the front seat 11.4 skiers waiting at the first boarding location 37. The seat 11.3, which was grouped at the previous seat 11.2 to cross the first location 37, separated from the latter seat 11.2, and he waits for the next seat 11.4 to cross the access track 40 of the second location 39, where it will embark skiers, who advance to this second location 39. The figure 9 represents this moment when the pair of seats 11.4,11.5 crossed the first location 37 and caught the seat previous 11.3, which advances, grouped with seat 11.4, to the second location 39 by crossing the access track 40. Seat 11.5, at the rear of the pair of seats 11.4,11.5, slowed down to separate from seat 11.4 and wait for seat according to 11.6 of the following pair 11.6,11.7. The seats 11.1,11.2 leaving the curve have boarded one 11.1 skiers in second location 39 and the other 11.2 skiers at the first location 37. It should be noted that the spacing between the pairs of seats 11.4,11.5 and 11.6,11.7 is more big as the spacing between seats, which would regularly spaced and that the passage of skiers between pairs of seats is thus easier. There is no point in describe in more detail how it works clearly from the examination of Figures 8 and 9.
