Description

[Detailed description of the invention] This invention provides a ski lift having non-detachable seats arranged at regular intervals on an aerial cable that is continuously let out along a closed track, in which the cable is attached to a ski lift at a departure station. A ski lift passing through a landing and comprising an access path to this landing, and means arranged at the entrance of the access path for effecting the entry of skiers into this access path in a rhythm corresponding to the seating rows. It is.

Known ski lifts of the type mentioned have an acceleration path in the form of a belt conveyor, the entry into which is controlled by rhythm means.

This device is complex and has never been implemented.

On conventional ski lifts, sideways walking is slow and inconvenient, and the previous skier blocks the next skier's progress.

The idea was based on the observation that the carrying capacity of a ski lift is actually limited by the speed with which skiers approach and board the ski lift at its starting point; The aim is to create a ski lift that allows users to board the ski lift easily and quickly.

In the ski lift of this invention, the approach path is a fixed approach path that makes an acute angle with the stool row track and concentrates on the landing area, and the skier who is moving forward in the same direction as the stools to depart will enter the gap between the adjacent stools. It has been made possible to do so.

Since the skier generally moves forward on the approach path, boarding time is significantly reduced.

Especially in the case of a three-seater ski lift, the boarding time is reduced.

By giving the approach path leading to the platform a slight slope of, for example, around 5%, and by making the slide as regular as possible, especially with a plastic carpet, the advance of the skier about to set off is facilitated.

The angle with the axis of the ski lift is 20 to limit the length of the approach path without significantly impeding the skier's progress.
It is preferable to set it around .

The landing can also be arranged below the terminal pulley.

The opening of the door or the departure signal given by the rhythm means is given by the passing of a seat preceding the seat of the skier waiting in front of the door at a predetermined position on the track, generally close to the door, where it The skier who enters chases this stool, but does not catch up with it and arrives at the landing immediately after this stool.

In this way, the skier has time to prepare to mount the stool in progress, which actually corresponds to the spacing of the stools.

Closing of the door can be accomplished in other ways, for example with timing that does not impede the path of departing skiers.

In the case of ski knots with multiple speeds, it is desirable to adjust the timing depending on the speed, but this of course reduces the simplicity of the device.

Timing also cannot take into account the irregular spacing of the seats along the cable, so door closing, as well as door opening, cannot be controlled by detecting the next seat passing a predetermined position. is desirable.

Such a control system can take into account different speeds and spacings of the seats and requires only simple initial adjustments.

This invention will be explained in detail below with reference to embodiments shown in the drawings.

In the figure, a ski lift type aerial cable transport device has seats 12, 14 at regular intervals along a cable 10, these seats being connected to the cable by means of non-removable attachment members. .

In the starting position shown, the cable 10 is connected to the terminal pulley 16
passing over the

This pulley is in particular a motive pulley that is continuously driven in rotation in the direction of the arrow.

The ascending and descending runs of the cable 10 also pass in front of a disembarking point 18 and a disembarking point 20, respectively, at which skiers step onto and off continuously moving stools, in a manner well known in the art.

The trajectory of the seat 12.14 corresponds to the trajectory of the cable 10,
Each stool has a limited area 22 indicated by the dashed line in the figure.
run.

The landing area 20 is a landing area 24 that coincides with the movement area 22.
, on which skiers who are about to depart (e.g. two skiers, indicated by two sets of skis in the figure) sit on a stool.

The approach path to the landing area 24 includes a portion 28 of a waiting skier's walking path 30.

The sides of the walking path 30 are limited by fences 31 or handrails, and this walking path 30 can pass around the pulleys 16 or, depending on the shape of the ground, take other trajectories, for example as shown by dotted lines in the figure. .

A ticket gate 35 is provided at the entrance of the walking path 30 at a distance sufficient to block traffic from the nearby path 28.

The walking path 30 is preferably approximately horizontal and free of sharp curves, so that skiers can walk normally in two lines.

The end of the walking path 30 is arranged substantially parallel to the seat movement area 22 and is connected to the adjacent path 28 .
8 reaches the landing 24 at an acute angle of about 20° with the cable 10 and with a small slope of, for example, 5%.

A plastic carpet (not shown) is used to improve sliding on this approach path 28.

Also, the walking path 30 and the approach path 28 can coincide with the trajectory of the seat immediately after the exit of the pulley 16.

At the entrance to the approach channel 28 there is a door 32 consisting of two pivoting half-doors 34, 36, which, when closed, prevents entry into the approach channel.

Each half door 34 , 36 is controlled by an electromagnetic device 38 , 40 which is opened and closed by an electric signal sent from a control center 42 . Door 3 after receiving the signal
The door 32 is commanded to open, and the door 32 is commanded to be closed in response to a signal from the seat passageway detector 46.

A detector 44 is located near the door 320 and is of the pivoting lever type that cooperates with the suspension system to actuate electrical contacts as the stool passes.

Upstream of this detector 44, at a distance less than the spacing between adjacent seats 12 and 14, a detector 46 of the same type is arranged;
It is thus activated after the detector 44 by a time corresponding to the spacing of the seats and their speed of advancement.

The control unit 42 includes a manual stop device, an automatic control device, and an emergency control device.

The aforementioned ski lift operates as follows.

In the position shown in the figure, two skiers 26 who are about to depart are waiting at a landing 24 for a stool 12 in order to board it.

The other skiers are lined up in two lines on the walking path 30, of which two skiers 50 are waiting for the door to be opened in order to enter the approach path 28.

When the seat 12 reaches the level of the passage detector 44, it activates this detector and initiates the opening of the door 32 via the control 42 and the electromagnet 38,40.

Detector 44 is positioned to open door 32 only when seat 12 is advanced out of reach of skier 50.

If the adjustment is made accurately, the skier 50 will arrive at the platform 24 immediately after the seat 12 on which the previous skier 26 was riding departs.

Because the approach path 28 is sloped, the skier 50 can move rapidly by skiing at a speed equal to or faster than the seat speed.

That is, this is because the approach path 28 has a slight downward slope.

Closing of the door 32 after two skiers 50 have passed through it is initiated by the seats 14 of these skiers 50 activating the detector 46 .

The door must be closed early enough to allow skiers coming through the door late to arrive at the landing 24 without colliding with the stool 14.

Or conversely, it's a good idea to keep the door open as long as possible, especially when there's no queue of skiers waiting.

It is also clear that when the stool 14 reaches the level of the detector 44, the cycle repeats and that the rhythm means from the detectors 44, 46 and the door 32 produce a rhythm of movement of the skier that corresponds to a rhythm of movement of the stool. Will.

The operation of this rhythm means is directly controlled by the seats 12, 14 and automatically accommodates variations in the speed and spacing of these seats, eliminating any malfunctions.

Of course, the detectors 44, 46 could be of another type, for example phototubes, and instead of the door 32,
Alternatively, lighting or acoustic signals can additionally be used.

The detectors 44, 46 may be configured not to detect the passage of packets.

In the embodiment shown, the control of the rhythm means is electromagnetic, but mechanical or hydraulic control can be provided.

According to another embodiment of the invention, the closing of the door 32 can be effected by a simple timing action, in which case the detector 46 is not required.

However, such a simplified device cannot take into account variations in the operating speed of the ski lift as well as the spacing of the seats, and the use of timing effects is only a compromise.

However, this method is also sufficient if the maximum transport amount is not desired.
