Description

The invention relates to a driving means for a cable car system, wherein the driving means comprises a cable car chair with two or more passenger seats and a suspension and a clutch, wherein the driving means by means of the suspension via the coupling in the region of a deflection station with a hoisting rope is connectable. The invention further relates to a cable car system with such driving resources.

There are today a variety of configurations of the driving equipment for cableway systems. In contrast to closed cable car cabins, users of cable car chairs sit, as it were, free on a mobile passenger seat. In this case, the driving equipment is coupled in operation via a coupling to a hoisting rope. The hoisting rope is at the same time carrying rope, is designed endlessly, and is guided in end stations via drive and deflecting wheels, wherein a plurality of driving means are connected to the hoisting rope and are moved by the latter. Depending on the transport length, the carrying cable is guided over a corresponding number of intermediate supports. Because the user is not simply sitting on a garden bench and can support the feet on the ground, but partly hovers at considerable heights above the ground, the driving means on safety devices that prevent falling out of the user while driving. Instead of the feet of the garden bench known from the prior art cable car chair is placed on a bracket. The bracket is designed as a suspension upwards, which is connected via a coupling with the hoisting rope.

There are three aspects in particular, which must be optimized again and again: The passenger not only wants to drive from the start to the destination, but also wants to have the greatest possible enjoyment on the way. The passenger desires the greatest possible comfort, especially when boarding a cable car chair. The operator of the cableway system wishes to transport a maximum number of passengers per hour.

DE 69 813 308 shows a chairlift with improved entry and assumes that the entrance and the exit ramp are parallel and the Umlenkrampe has two curves, a entrance-side and exit-side curve, which are separated by a straight-line transfer ramp and at the skiers are pending in the extension line of the exit ramp. For this purpose it is proposed: <tb> 1. <SEP> that there is an entry point at the end of the exit side turn; <tb> 2. <SEP> that the angle a between the entrance ramp and the transfer ramp, which corresponds to the entrance-side curve, is an acute angle, <tb> 3. <SEP> and that the angle between the transfer ramps and the exit ramp corresponding to the exit side turn is an obtuse angle.

It is expected that the passenger transport for the passenger can be increased without disadvantages. It is also proposed that the new support station of a chairlift is formed with above-ground, continuously circulating cable, characterized in that the entrainment elements pivot each armchair about its own axis at the level of the transfer ramp prior to application; further, that the driver elements rotate the seat by the angle Φ, causing the front of the seat to approach the queue from the side, in a position that clearly demonstrates the sensation of being "swept along" in the curves decreases, which increases with the seat width.

DE-PS 551 780 shows as the oldest state of the art an observation trolley for passenger cable cars. It has been found that in known cable cars, the evil is the result that the passengers are bound to the once occupied places and thus to a specific and limited view. This results in some inconvenience before the start of the journey, because all passengers seek to obtain places that offer the best view while driving. During the journey, however, the enjoyment is greatly impaired or questioned for those passengers who are given a bad seat and rely throughout the ride on a less beautiful, perhaps unfriendly panorama. As a solution, it is proposed that the car is rotatable by hand or by power drive about its gravity axis. For this purpose, the observation car is hung up on the rope via a hanger. The observation car hangs down on the hanger and is mounted by means of a pair of wheels and can e.g. be offset by a fed in an accumulator battery electric motor in a rotary motion.

FR-PS 2 692 858 proposes to rotate by means of rotary motion a cable car nacelle via a rotary drive in the region of an end and deflection station in a respective desired position. At the same time, the gondola acceleration and deceleration is also carried out in the area of entry and exit of the persons.

The AT 002 469 proposes to store both closed gondolas as cable car chair rotatable about a vertical axis. Such a solution can mean an increase in driving pleasure in cabins that are closed on all sides. For many people, spinning around on a cable car chair can cause unpleasant sensations or even anxiety. With the pivot bearing the special effect is placed in the foreground, with each passenger can enjoy the most beautiful view with a full turn.

The new invention has now been based on the object to look for concepts, which at the same time avoids the disadvantages of the solution of the prior art for cable car chair at least in part and optimizes the above-mentioned aspects.

The inventive solution is characterized in that the suspension has a trained as a pivot bearing pivot bearing with a vertical axis, for pivoting the cable car chair in the region of the deflection in the clockwise or counterclockwise direction in an angled to the direction of travel.

The new invention allows to solve all three optimization tasks simultaneously. The pivoting of the cable car chair gives the advantage that the entry is greatly reduced in space and that the entry can be accelerated without any disadvantage to the passenger. But this can also increase the transport performance of the cable car system.

Most preferably, the suspension has a hanger arm and a support arm, wherein the pivot bearing connects the hanger arm with the support arm. The new invention relates in particular to cable car chair and has three aspects in the foreground with the pivot bearing: the driving equipment is allowed only a limited twisting movement. The rotational movement is made as a particularly preferred solution in the area of the deflection stations. It should be avoided, in particular, that the passenger while driving only just look at the back of the previous cable car chair.

This can also be prevented, in particular, that the cable car chair while driving, for example, in addition to uncontrollable wind movements still performs rotational movements, which can only be harmful for people with this in this increased anxiety.

The new invention allows a whole number of very particularly advantageous embodiments.

Advantageously, the driving resources in the area of both deflection stations of the cable car system is associated with a pivoting mechanism, for pivoting the passenger seats in an angled to the direction of travel, and for pivoting back into an optimal position for getting in and out. The pivot angle is less than 180 °, preferably approximately in the range of 20 ° to 90 °, optimally about 45 °.

According to a particularly advantageous embodiment of the support arm is rigidly connected in the back region of the cable car chair with a carrier, in particular a horizontal beam of the cable car seat and extends as a support arm to over the range of a vertical axis of gravity of the cable car seat, which corresponds to the vertical axis of the pivot bearing.

Preferably, the pivot bearing is designed as a fork bearing and is designed for a free rotational movement of less than 180 °.

According to a further particularly advantageous embodiment of the hanger arm and the support arm are formed as curved or bent bending carrier. This can be optimized for the first suspension with respect to the cable car seat and above all, space in the head area are created for the adjustable guards such as hoods and a horizontal safety rails.

Advantageously, the pivoting or Rückschwenkung is carried out at the entrance or exit of both deflection stations, wherein the pivoting is set at the exit at each exit and the pivoting between the two deflection stations remains unchanged. The pivoting device can be designed so that it takes place via mechanical means. According to a further embodiment, the pivot bearing can be driven by a controllable electric motor, wherein the power supply in the region of the two deflection stations, e.g. via an inductive current decrease or via an eddy current principle can take place. As a power source, solar power can be used in the area of each person seat or power is supplied via a rechargeable storage.

Preferably, the acceleration and deceleration of the driving resources in the field of deflection stations of the cable car is feasible, the acceleration and deceleration of the driving resources can be done via a friction wheel.

According to a very particularly advantageous design ideas the friction wheels are assigned to a device for energy recovery and the device and power storage for the acceleration of the driving resources.

According to the second embodiment, the driving resources in the entry area of the deflection in the first 90 ° -Umlenksektor in the clockwise direction at an angle of about 45 ° and in the second 90 ° -Umlenksektor counterclockwise about 45 ° swung back.

Preferably, the entry ramp and the exit ramp are connected to a Umlenkrampe with a deflection angle of 180 °, wherein in straight continuation before the exit an entry for waiting skiers is arranged, are arranged on which controllable barriers.

Further, a control device is provided, by means of which only ever a driving resources in the area of the second Umlenksektors is located, so that can enter only with the exit of a occupied cable car chair of the next cable car chair in the second deflection sector.

The acceleration and deceleration of the driving resources is optimized only in the actual boarding area, which is intended for passengers.
