Definitions
- the invention relates to a boarding device for chairlift with fixed clamps.
- the invention relates more particularly to a boarding device for cable chairlift and vehicles with fixed clamps.
- the chairlift with detachable vehicles is a chairlift with a high speed, therefore a high cable speed, but which requires at the embarkation or disembarkation station to disengage the vehicle on a secondary circuit so that skiers can be loaded and unloaded at speeds in line with their safety.
- Such devices provide good security and a high flow rate but require a substantial initial investment and significant maintenance due to the secondary declutching circuit and the fatigue caused by the disengageable clamps of vehicles undergoing a multitude of clutch / declutching cycles (four on one way / vehicle return).
- the second category of chair lifts is called a vehicle with fixed clamps.
- the vehicles are not detachable from the conveyor cable.
- the main limit on the speed of a chairlift with fixed clamps is due to the limit imposed by the relative speed of the vehicle in relation to the user.
- Such devices with vehicles with fixed grippers are of course much lower in cost than devices with detachable grippers.
- Manufacturers of fixed-grip chairlifts in order to increase the speed of their chairlifts have developed boarding devices that set the user (s) in motion. Therefore, for a constant vehicle / user relative speed, by giving an initial speed to the users, the speed of translation of the cable is increased by this initial speed and therefore the hourly speed of the chairlift with fixed clamps is increased.
- such boarding devices for chairlifts with fixed grippers comprise a conveyor belt moving at a continuous speed synchronized with the speed of the cable from the chairlift and upstream of which there is an inclined acceleration ramp for passing the user (s) from a substantially zero speed up to substantially the constant speed of said conveyor belt.
- Such devices have their limit insofar as the acceleration induced by the inclined acceleration ramp, and therefore the speed v1 of the conveyor belt is limited on the one hand by the safety of the user and on the other hand by the length of the inclined acceleration ramp.
- One of the aims of the present invention is to make it possible, for a given acceleration, to significantly reduce the distance of the acceleration band.
- another object of the present invention is to allow, for a given length of acceleration band, to obtain an output speed v1 greater than that known from the prior art.
- the invention relates to a boarding device for cable chairlift and vehicles with fixed clamps comprising at least one conveyor belt moving at a continuous speed synchronized with the speed of the cable of the chairlift, further comprising upstream of the conveyor belt at least one acceleration belt for passing at least one user wearing skis at a substantially zero speed up to substantially the constant speed of said conveyor belt, and upstream of the acceleration belt, a path access and queues.
- the acceleration belt is substantially raised relative to the conveyor belt so that the front part of the skis comes into contact with the conveyor belt only when the center of inertia of the user passes beyond from the downstream end of the acceleration band.
- the invention relates to a boarding device for chair lifts as described above, the acceleration band further comprising a plurality of lanes in particular in number equivalent to the number of seats on each vehicle, each lane being provided on either side of a mobile ramp (handrail) accelerated synchronously with the acceleration band.
- FIG. 1 is a schematic side view of a boarding device for chairlift according to the invention.
- FIG. 2 is a schematic top view of the representation of Figure 1.
- FIG. 3 is a view along arrow A of the representation of Figure 1.
- the invention relates to a boarding device for users of cable-driven chairlifts and vehicles with fixed clamps.
- the user boarding device comprises from upstream to downstream an acceleration system 1 making it possible to pass a user wearing skis at an initial speed substantially zero up to a speed vl; this acceleration system 1 is followed by a transport system 2 of the user or users wearing skis allowing transport at constant speed vl of the user or users over a certain distance.
- the transport system 2 also acts as a pier for the user (s) on the vehicles 4 with fixed clamps 7 of the chairlift 3 with cables 5. Said vehicles 4 being driven at a constant speed v2 greater than the constant speed v1 of the transport.
- the acceleration system 1 further comprises movable handrails 8 defining a certain number of lanes 9 in particular in a number equivalent to the number of seats 16 on each vehicle 4. These mobile handrails 8 are subjected to the same clocked movement as the strip d acceleration of the acceleration system 1. Therefore, the user or users undergoing acceleration have an additional point of support of the hand on the handrails 8. Thus the user or users do not risk to tilt backwards under the effect of acceleration on their own inertia.
- the upstream end of the acceleration system 1 comprises transition means 11 between the waiting wire path 10 and the acceleration system 1.
- the purpose of these transition means 11 is to position the front part of the skis a few centimeters above the acceleration band la so that users in waiting are not driven by the acceleration band la while users are already present.
- transition means 11 Another object of these transition means 11 is to limit the frictional forces of the rear part of the skis of a user driven by the acceleration band 1a of the acceleration system 1.
- these transition means are free roller means 11. These roller means 11 have an axis of rotation perpendicular to the direction of acceleration of the acceleration system 1.
- the roller means 11 are arranged or have a diameter such that it creates a negative drop 15 with the acceleration system 1 so that the user (s) on standby have the front part of their skis positioned a few centimeters above the strip of acceleration of the acceleration system 1.
- roller means 11 can be either a single roller 11 for all of the corridors 9 or several rollers 11 of the same axis 17, each intended for a corridor 9 and being free to rotate independently of the others.
- the downstream end of the acceleration system 1 is extended by the transport system 2.
- the transport system 2 according to the embodiment shown in the figures comprises a rotating conveyor belt 2a driven by a motor (not shown) at a speed constant vl and whose upper face is horizontal and moves from upstream to downstream.
- the upper face of the conveyor belt 2a is slightly elevated 14 relative to the acceleration belt 1a of the acceleration system 1.
- the front part of the skis of the accelerated user (s) does not come into contact with the belt conveyor 2a only when the center of inertia of the user (s) passes beyond the downstream end of the acceleration band la.
- the transport system 2 also constitutes the loading system for the user (s) on the vehicles 4 of the chairlift 3.
- the process for boarding the user (s) on the vehicle 4 of the chairlift 3 is equivalent to that existing when the user (s) statically await the arrival of the vehicle.
- the only difference comes from the fact that in the present invention the user (s) have an initial speed vl, and the vehicle 4 of the chairlift 3 has a speed v2 representing the sum of the speed vl with a boarding speed conventionally used in the devices boarding of static users.
- a negative drop 14 is made on the order of 1 to 2 meters to prevent the latter from being struck by the vehicle 4 in the event of a fall by one or more users. was intended to charge them.
- the boarding device further comprises, upstream of the acceleration system 1, clocking means 12 movable between two extreme clocked positions, namely:
- timing means 12 comprise timing gates 12, each blocking or releasing access from an associated corridor 9.
- the operation of the device will now be described by following the successive stages undergone by an on-board user.
- the user presents himself in front of one of the lanes 9, the front part of the skis being raised relative to the acceleration band 1a of the acceleration system 1 thanks to the free rollers 11.
- the clocked gate is in the closed position.
- the acceleration band 1a is stopped, the clocked gate passes to the open position, the user advances with the help of the handrail 8 which is also stopped. At this stage, at least the front part of the user's skis is in contact with the acceleration band 1a, the user having also taken support on the handrail 8.
- the acceleration strip 1a and the handrail 8 as well as the user are subjected to the acceleration cycle of the acceleration system.
- the clocked gate passes to the closed position.
- the front part of the user's skis is raised a few centimeters above the transport system so that the user / skis assembly can still be accelerated without it there is a distortion between the constant speed of the transport system and the accelerated movement of the acceleration system 1.
- the center of gravity of the user passes the downstream end of the acceleration system 1, the user switches to the conveyor belt of the transport system 2, its speed being then substantially equal to the speed v1 of the transport system 2.
- the above steps are synchronized with the vehicle 4 of the chairlift 3 so that once the user on the transport system 2, said vehicle considered to have a speed v2 greater than vl comes to pick up the user before l downstream end of the transport system 2.
- the new user arrives on the transport system 2 after the passage of the vehicle 4 of the chairlift 3 intended for the first user.
- the device according to the invention it is possible to obtain at much lower costs ski flows equivalent to those of chairlifts with detachable grippers. It will thus be possible to obtain speeds v2 of vehicles with fixed pliers of the order of 3.5 to 4 meters / second compared to the conventional speeds known on chair lifts with vehicles with fixed pliers and with static boarding which are of the order of 2.30 to 2.5 meters / second.
