Description

Cable car support with a step-over device

The invention relates to a cable car support of a cable car with an entry unit for people to enter. The invention also relates to a cable car with a number of cable car supports for guiding a hoisting rope of the cable car and with at least one cable car arranged on the hoisting rope, as well as a method for carrying out a climb from a cable car to the entry unit or vice versa.

Cable cars come in a wide variety of designs, mostly for transporting people and / or goods, for example as urban means of transport or for transporting people in ski areas. Funicular railways are known, in which mostly rail-bound vehicles are attached to a wire rope in order to be pulled by the wire rope. The

Movement takes place on the ground, with funiculars mostly used on mountain routes. In the case of cable cars, on the other hand, cable car cars such as Gondolas, cabins or armchairs carried by one or more (wire) ropes without fixed guides and moved while hanging in the air. So the cable car cars don't have one

Ground contact. Cable cars are usually used in rough terrain, mostly for mountain routes, for example in ski areas, to transport people from the valley to a mountain. As a rule, cable cars have two stations between which the cable car cars are moved.

A distinction must be made between orbits and aerial tramways. In the case of aerial tramways, one or two cable car cars, pulled by a pulling rope, shuttle back and forth on a haulage rope on a lane between two stations. The circulating cable car, on the other hand, has an endless, constantly revolving hoisting cable between the stations, on which a large number of cable car cars such as gondolas, cabins or armchairs are suspended. The cable car cars are moved from one station to the other on one side and back again on the opposite side. The movement of the cable car is therefore always essentially continuous in one direction, analogous to a continuous conveyor.

In order to be able to bridge larger distances, one or more cable car supports for guiding the (supporting / pulling) cable (s) are usually arranged between the two stations. Cable car supports can be designed as a steel framework, but also as a steel tube or sheet metal box construction. A number of rollers are usually arranged on a cable car support, for example in the form of a so-called roller battery to carry and guide the cable. To carry out maintenance and repairs on the cable car supports,

To be able to perform in particular on the rollers, access units are often provided on the cable car supports. Such entry units can for example be in the form of (maintenance) platforms and / or steps and can be from

Maintenance personnel are entered. In addition, security devices be provided to increase the safety for maintenance personnel, for example railings.

Depending on the intended use and the terrain, cable car supports can be between a few meters and more than 150 m in height. Until now, access to the access units for the cable car supports was only possible via ladders from the ground. However, due to the often impassable terrain and especially because of the sometimes great heights of cable car supports, such an approach is very difficult and time-consuming.

It is therefore an object of the invention to provide an easier approach to one

To enable entry unit of a cable car support of a cable car.

The object is achieved according to the invention in that on the cable car support a

Climbing device is provided for people to cross over from a cable car of the cable car to the entry unit or vice versa, the transfer device being movable relative to the entry unit by means of a fastening unit

Cable car support is arranged, the step-over device being displaceable relative to the stepping-over unit from a rest position in which the step-over device is stowed on the step-over unit into a readiness position which is provided for carrying out the step-over. This makes the boarding to the entry unit directly from one

Cable car made possible, which is much less strenuous and less time-consuming for maintenance personnel than via a ladder from the ground.

A locking unit for locking the climbing device in the rest position is preferably provided on the cable car support. This makes it possible to reduce the risk of the step-over device becoming detached in an undesirable manner, for example during operation of the cable car.

A mechanically, hydraulically or electrically operated locking unit enables flexible options for operating the locking unit.

An actuating unit for actuating the locking unit is advantageously provided on the cable car support in order to release the locking of the climbing device in the rest position in order to move the climbing device from the rest position into the

To move the readiness position, the actuating unit preferably having at least one first lever element to actuate the locking unit from a cable car, the actuating unit particularly preferably also having a second lever element to actuate the locking unit from the entry unit. According to a further advantageous embodiment, the actuation unit can also have an actuation means in the form of a cable pull or a flexible shaft. This creates flexible options for simple actuation of the locking unit. It is advantageous if the step-over device has a braking device in order to brake a movement of the step-over device from the rest position into the ready position caused by gravity, the braking device preferably being mechanical, hydraulic or pneumatic. This can increase safety and reduce the risk of injury to people.

Preferably, the cable car support has at least one sensor element that is used for

Detection of a position of the climbing device is provided, in particular to detect whether the climbing device is in the rest position, the sensor element generating a sensor value which can be transmitted to a system control unit of the cable car. The sensor element can also be provided, a

Detect locking state of the locking unit, in particular whether the

Climbing device is locked in the rest position by means of the locking unit. This further increases safety, since reliable detection of the position and / or the locked state of the step-over device is made possible.

The step-over device preferably has at least one step and / or holding element for a person to step on and / or hold. This makes it easier for people to cross over and increases safety.

It is furthermore advantageous if a length of the crossing device can be changed by the length of the crossing device to a variable distance between the

To adapt the entry unit and the cable car, the step-over device being particularly preferably designed as a ladder, preferably as a telescopic ladder, the at least one step and / or holding element being a rung of the ladder.

Preferably, a railing is provided on the entry unit and the

Climbing device forms part of the railing in the rest position, which can increase safety.

The object is further achieved in that the step-over device is arranged on at least one cable car support of a cable car, preferably on several

Cable car supports each have a climbing device.

The cable car advantageously has a system control unit for controlling the cable car, the system control unit being provided to process the sensor value of the sensor element in order to switch off the cable car or to generate a warning signal and output it via a signal device when the sensor element is in a position deviating from the rest position Climbing device detects and / or when the sensor element is in an unlocked state of the climbing over device

Locking unit recognizes. Through the communication of the sensor of the

Climbing device with the system control unit makes it possible to switch the cable car into Switch off depending on the position and / or the locked state of the step-over device or at least emit a warning signal.

The object is also achieved with the method mentioned at the beginning, wherein the

Cable car is moved into a step-over position, the step-over device of the cable car support is moved from the cable car or from the entry unit from the rest position to the ready position, a person climbs over the cable car via the step-over device to the step-over unit or vice versa and the step-over device after the step is preferably from the Entrance unit from or from the cable car from the ready position BP is shifted back into the rest position.

The present invention is explained in more detail below with reference to FIGS. 1 to 5b, which are advantageous by way of example, schematically and not by way of limitation

Show embodiments of the invention. It shows

Embodiment of the invention,

1 shows a cable car support 1 of a cable car 2 with a roller set 3 and an entry unit 4. The structure of a cable car 2 is known in principle, which is why only the components essential for the invention are described here. The roller set 3 has a number of rollers 5 arranged one behind the other, on which a conveyor rope 6 of the cable car 2 is guided. The roller set 3 is on the

Cable car support 1 attached to support the load on the hoist rope 6 and in particular the cable car 7 arranged thereon via the cable car support 1 on the ground. A plurality of cable car 7 are usually suspended at a certain distance from one another on the hoisting rope 6. A cable car 7 can be fastened to the hoisting rope 6, for example, as shown by means of a releasable clamping mechanism 8, in order to be able to decouple the cable car from the hoisting cable 6 in a station. The decoupling can take place, for example, in order to reduce the speed while driving through the station in order to enable easier entry and exit of people. A decoupling can, for example, also after a closing time Cable car take place in order to park the cable car outside of the operating hours, e.g. in a suitable garage. Of course, a non-uncoupling connection of the cable car 7 to the hoisting cable 6 would also be possible. In the example shown, the cable car 7 is designed as a maintenance gondola. The maintenance gondola has a ladder 9 by means of which a person can climb from the maintenance gondola onto a platform 10 at the upper end of the maintenance gondola, for example in order to carry out certain maintenance activities.

The entry unit 4 of the cable car support 1 is designed here as a staircase that has a longitudinal beam 11 and several steps 12. The entry unit 4 can be attached to the roller set 3 and / or to the cable car support 1 itself. In the example shown, a railing 13 is additionally provided on the steps 12 in order to increase the safety for people when using the entry unit 4. Of course, this is only an example; the entry unit 4 could also be constructed in any other way and e.g. only have a platform with or without a railing 13. If the cable car support 1 is designed as a framework construction, the entry unit 4 could for example also be a direct part of the cable car support 1.

A maintenance ladder 14 is schematically indicated on the cable car support 1, via which persons, in particular maintenance personnel, can ascend from the ground to the entry unit 4. Of course, such a maintenance ladder 14 can also have additional safety elements, for example a type of cage, in order to secure people from falling. Up to now, access to the entry unit 4 has essentially only taken place via such maintenance ladders 14. It is immediately apparent that the access via the maintenance ladder 14 is very strenuous and time-consuming, especially with very high cable car supports 1, which is of course disadvantageous. In addition, there is the additional difficulty that cableway supports 1 are often in impassable, e.g. are arranged steep, rocky terrain, whereby even reaching the cable car support 1 on the ground is very difficult. In addition, one is restricted when using a maintenance ladder 14 with regard to luggage such as tools.

In order to make it easier for people to board the entry unit 4, it is therefore provided according to the invention that a step-over device 15 is arranged on the cable car support 1 for a person to climb over from a cable car 7 of the cable car 2 onto the entry unit 4. The step-over device 15 is pivotably arranged on the entry unit 4 by means of a fastening unit 21 and is relative to the step-over unit 4 from a rest position RP, in which the step-over device 15 is stowed on the step-over unit 4, into a readiness position BP, which is provided for performing the step-over , relocatable. In FIG. 1, the step-over device 15 is shown in a first embodiment, the structure and mode of operation of which is explained in greater detail below with reference to FIGS. 2a, 2b and 3. The step-over device 15 is located in FIG. 1 in the ready position BP, in which step from the cable car 7, for example from the platform 10 of the maintenance gondola, to the access unit 4 is made possible. The step-over device 15 is here pivotably attached to the lowest step 12 of the entry unit 14 and can be moved, in particular pivoted, from the rest position RP (not shown) into the shown ready position BP for use by one person from the cable car 7. For this purpose, the cable car 7 is moved sufficiently close to the entry unit 4 in a step-over position and is stopped. Then a person can climb onto the platform 10 via the ladder 9 of the cable car 7 and the step-over device 15 can be folded from the rest position RP into the ready position BP from the platform 10 in order to get to the entry unit 4, here on the stairs. Of course, the crossing can also take place the other way round, in that a person (who is on the entry unit 4) moves the crossing device 15 from the rest position RP to the ready position BP from the entry unit 4 in order to get from the entry unit 4 to the cable car 7.

The step-over device 15 preferably has at least one step and / or holding element 16 which is suitable for being held or stepped on by a person in order to facilitate the step-over. The step-over device 15 can advantageously be embodied as a ladder, for example, as shown, the ladder having several rungs as step and / or holding elements 16. According to a further advantageous embodiment, a length of the step-over device 15 can be changed in order to be able to adapt the step-over device 15 to a variable distance between the entry unit 4 and the cable car 7. This also makes it easier for people of different sizes to cross over and the positioning of the cable car 7 in the crossover position can be less precise. If the step-over device 15 is designed as a ladder, the variable length can be implemented, for example, by a telescopic ladder, the structure and function of which are known.

2a and 2b show the step-over device 15 from FIG. 1 in detail in different perspectives in the rest position RP. For the sake of clarity, only part of the entry unit 4, for example the lowest step 12, and part of the railing 13 are shown. The step-over device 15 is connected in an articulated manner to the fastening unit 21 and the fastening unit 21 is firmly connected to the stepping-on unit 4, for example screwed, as shown. In the example shown, the fastening unit 21 has a left and right bracket 17, between which the step-over device 15 is pivotably fastened.

A locking unit 18 is preferably provided on the cable car support 1, in particular on the entry unit 4 or the fastening unit 21, in order to Climbing device 15 releasably lock in the rest position RP. The locking unit 18 can preferably be actuated mechanically, hydraulically or electrically. Safety can thereby be increased, since it is ensured that the step-over device 15 is not moved in an undesired manner from the rest position RP partly in the direction of or completely into the ready position BP. Preferably, the cable car support 1 also has an actuating unit 19 for actuating the locking unit 18 in order to release the locking of the step-over device 15 on the entry unit 4 or the fastening unit 21 in order to be able to move the step-over device 15 from the rest position RP to the ready position BP, such as is symbolized by the arrow in Fig.2a and Fig.2b.

In the example shown, the locking unit 18 and actuating unit 19 are arranged on a console 20, but of course they could also be arranged on the entry unit 4, for example on the railing 13. The console 20 is here connected to the consoles 17 via a cross strut (FIG. 2a) connected, resulting in a substantially one-piece fastening unit 21 for the pivotable fastening of the step-over device 15 on the entry unit 4, which at the same time has the locking unit 18 and the actuating unit 19. The one-piece design of the fastening unit 21 can improve the structural rigidity and the assembly of the step-over device 15 on the entry unit 4 can be made easier, since the entire step-over device 15 including the fastening unit 21 and the locking unit 18 and actuating unit 19 provided on it is designed as a module. In addition, the console 20 can for example also be attached to the entry unit 4, here on the railing 13, in order to further improve the structural rigidity. This is particularly advantageous in order to reduce vibrations during the step over, which increases the feeling of security for the person.

In FIG. 3, the crossing device 15 is shown in the ready position BP, in which the crossing from the cable car 7 can take place (see FIG. 1). The step-over device 15 is designed here as a ladder which is articulated to the brackets 17 of the fastening device 21 by means of lateral holders 22. In this way, for example, a conventional, commercially available ladder can be used as the step-over device 15, the ladder preferably being made of a light, weather-resistant material with sufficient strength, for example aluminum. Of course, the step-over device 15 could also be connected to the fastening unit 21 in an articulated manner directly, that is to say without brackets 22. The use of a ladder and holders 22, however, has the advantage that the ladder can be easily exchanged, for example in the event of damage and / or that ladders of different lengths can be used. The actuating unit 19 advantageously has at least one first lever element 24 a in order to actuate the locking unit 18 from the cable car 7. Particularly preferably, however, the actuation unit 19 also has a second lever element 24b in order to be able to actuate the locking unit 18 also from the entry unit 4 (FIG. 2b). In the example shown, the lever elements 24a, 24b are made in one piece with the actuating unit 19, the first lever element 24a extending in the direction of the ready position BP (here essentially vertically downwards) and the second lever element 24b in the direction of the rest position RP (here essentially vertically upwards). The actuating unit 19 is here rotatably fastened to the bracket 20 and can be displaced between a locking position and a release position. A biasing element 26, such as a suitable spring, is advantageously additionally provided in order to bias the actuating unit 19 into the locking position in which the step-over device 15 is locked on the entry unit 4. To release the lock, the actuating unit 19 is counter to a biasing force of the

Biasing element 26 displaceable into the release position, wherein the step-over device 15 can be pivoted in the release position from the rest position into the readiness position.

The locking unit 18 is designed in the example shown as an opening 25 in the actuating unit 19, which with a pin 27 (Figure 2b) of

Climbing device 15 interacts to lock the climbing-over device 15 in the rest position RP on the entry unit 4. In the example shown, the pin 27 is arranged on the outside of the left holder 22 of the ladder and in the rest position RP in engagement with the opening 25. If the step-over device 15 is made in one piece (without holder 22), then the pin 27 is preferably directly on the side provided on the climbing device 15. If the actuating unit 19 is actuated by one of the two lever elements 24a, 24b, i.e. pivoted from the locking position into the release position against the pretensioning force of the pretensioning element 26, the opening 25 releases the pin 27 and the step-over device 15 can move from the rest position RP into the ready position BP be shifted, in particular pivoted.

Of course, the actuation unit 19 can be designed in any other way, in order to lock and hold the step-over device 15 in the rest position RP and to release the step-over device 15 when it is actuated.

When the step-over device 15 is no longer required, for example after the maintenance work on the roller set 3 has been completed, the step-over device 15 is preferably relocated back to the rest position RP in order not to endanger the operation of the cable car 2. This can in turn be done from the cable car 7 by the Climbing device 15 is manually folded back from the ready position BP into the rest position RP. The step-over device 15 can also be moved from the entry unit 4 back to the rest position RP, for example if a person remains on the entry unit 4 to check or monitor certain functions of the roller set 3 during the operation of the cable car 2, for example. In order to facilitate the folding up of the step-over device 15 from the entry unit 4, a grip element 23 can be provided on the step-over device 15. In the example shown, the grip element 23 is designed as part of the right holder 22, but of course other variants would also be conceivable, for example a separate grip element 23.

If a railing 13 is provided on the entry unit 4, the step-over device 15 advantageously forms part of the railing 13 of the entry unit 4 in the rest position RP.

The step-over device 15 can preferably be displaced from the rest position RP into the ready position BP by means of gravity as soon as the locking of the locking unit 18 is released by means of the actuating element 19. However, it can be advantageous if the step-over device 15 has a braking device (not shown) in order to brake a movement of the step-over device 15 caused by gravity from the rest position RP to the ready position BP. This can increase safety, since the step-over device 15 cannot move downward in an uncontrolled manner and possibly injure a person. The braking device can also be advantageous in order to avoid damage to the step-over device 15. For example, an inadmissibly high load on the articulated connection (here between bracket 22 and brackets 17) can be prevented and / or damage or deformation of the step-over device 15, e.g. of the (aluminum) conductors shown. The braking device is preferably designed mechanically, hydraulically or pneumatically, for example as a gas pressure spring. The braking device could, however, be implemented, for example, by specifically increasing the friction in the joints.

Furthermore, it is advantageous if at least one limiting element 28 is provided which limits a movement of the climbing device 15 beyond the rest position RP. In the example shown, a limiting element 28 is arranged on the left and right, which essentially serves as an end stop for the climbing device 15. The

Boundary elements 28 are here attached to console 20 (left) and console 17 (right) of the one-piece fastening device 21. Of course, another arrangement would also be conceivable, for example on the entry unit 4, for example on the railing 13. If the delimitation elements 28, as shown, each have an elastic damping element, such as a rubber element, the step-over device 15 can strike are damped on the limiting element / s 28 in the rest position RP. As a result, an abrupt impact of the pin 27 in the opening 25 on the actuating unit 19 can be avoided, whereby damage can be avoided. In addition, the damping elements can be used for prestressing in order to prestress the pin 27 in the rest position RP against a delimitation of the opening 25. This can prevent the step-over device 15 from moving within an existing play between the pin 27 and the opening 25, which under certain circumstances could lead to vibrations and rattling noises, for example caused by wind.

Furthermore, it can be advantageous if the entry unit 15 has at least one

Has sensor element 29, which is provided to detect a position of the step-over device 15, in particular to detect whether the step-over device 15 is in the rest position RP. The sensor element 29 generates a sensor value which can be transmitted to a system control unit (not shown) of the cable car 2. The sensor element 29 is particularly preferably provided to detect whether the step-over device 15 is locked in the rest position RP by means of the locking unit 18 on the entry unit 4. In the example shown, the sensor element 29 is so-called

Executed limit switch, which is actuated by the climbing device 15 when the climbing device 15 is in the rest position RP and generates a corresponding sensor value. The system control unit of the cable car 2 can process the sensor value and switch off the cable car or output an alarm signal if it is recognized by the sensor 29 that the climbing device 15 is in one of the

Rest position RP is different position. If a suitable sensor 29 is provided for detecting the locked state of the locking unit 18, the system control unit can switch off the cable car when the sensor detects an unlocked state of the climbing device 15 in the locking unit 18.

FIG. 4 shows a further exemplary embodiment of a cable car support 1 with a roller set 3 and a hoisting rope 6 on which a cable car 7 is suspended. Analogously to FIG. 1, the cable car support 1 has an entry unit 4. The section of the roller set 3 to the left of the cable car support 1 is cut away in FIG. 4 for better visibility of the entry unit 4. The entry unit 4 has a longitudinal beam 11 and several steps 12. The steps are each arranged on a cross member 30, here in the form of a tube, the cross members 30 being firmly connected to the longitudinal member 11. The step-over device 15 is also designed here as a ladder and is arranged pivotably on the step-on unit 4 by means of a fastening unit 21.

The fastening unit 21 here has two eyes, which are arranged on the cross member 30 of the lowermost step 12, so that the cross member 30 or the pipe extends through the eyes. As a result, the cross member 30 is essentially used as an axis of rotation pivot the climbing device 15 used. Of course, it would in principle also be sufficient if the fastening unit 21 only has one eyelet, but two or more eyelets are advantageous in order to ensure greater stability of the connection

Generate transition device 15. In particular, lateral tilting or wobbling of the crossing device 15 during the crossing is reduced, thereby increasing the feeling of security. The at least one eyelet can be made rigid, for example, from a suitable metallic material or from a flexible material of suitable strength, e.g. Plastic or a textile fabric.

In the rest position RP, the climbing device 15 is below the

Entrance unit 4 and extends essentially parallel to the longitudinal beam 11, as can be seen in Figure 4. The locking unit 18 is arranged here on the entry unit 4 and has a locking element 18a which is rotatably mounted on the entry unit 4, for example on the longitudinal beam 11. The axis of rotation in the locking element 18a runs essentially parallel to the transverse beams 30 or pipes which the steps 12 are arranged. In the rest position RP, the locking element 18a is in engagement with the transfer device 15 in order to lock the transfer device 15. In the example shown, the locking element 18a has an opening which, in the rest position RP, engages with a rung of the ladder in order to fix the ladder in the rest position.

The actuation unit 19 for actuating the locking unit 18 has a first lever element 24a in order to be able to actuate the locking unit 18 from a cable car 7 when the cable car 7 is in a suitable (not

shown) step-over position. The first lever element 24a can for example by means of a cable pull or a flexible shaft of a corresponding length with the

Locking unit 18 can be connected to release the lock, for example to pivot the locking element 18a in the example shown. After releasing the lock, the step-over device 15 can move from the rest position RP to the

Relocation position BP shifted, here in particular pivoted about the axis of rotation of the lowermost cross member 30.

If the locking unit 18 can be actuated electrically, the actuating unit 19 could, for example, also be an electrical switch which is connected to the locking unit 18 via an electrical line (this of course also applies to other embodiments of the invention). Wireless actuation of the electrically actuatable locking unit 18 would also be conceivable, for example. In this case, the actuation unit 19 could e.g. be a radio switch, for example stationary at a suitable point of the

Cable car support 1 can be arranged, for example on the entry unit 4. However, it would also be conceivable for several radio switches to be provided in order to prevent the locking unit 18 operated from different positions. Of course, it could also be a portable one

Radio switches are used, for example, to enable activation or unlocking of the climbing device 15 from the cable car 7.

In the ready position BP, the step-over device 15 or ladder extends essentially vertically downward from the entry unit 4, as indicated by dashed lines in FIG. The shift is preferably carried out simply by gravity, it being particularly advantageous in this embodiment if a braking device (not shown) is provided to brake the movement of the step-over device 15 from the rest position RP to the ready position BP. As already mentioned with reference to the first embodiment, the braking device can, for example, as

Be formed gas pressure spring. But e.g. also that a mechanical spring is provided, which the movement of the step-over device 15, which in the

Essentially corresponds to a free fall, to counteract. For example, a torsion spring could be provided on the lowermost cross member 30, which serves as a pivot axis for the step-over device 15. Of course, this is only to be understood as an example and the person skilled in the art could also provide other suitable braking devices.

Optionally, a second lever element 24b could of course also be provided in order to actuate the locking unit 18 from the entry unit 4. For example, the second lever element 24b, as indicated in FIG. 4, could be arranged directly on the locking element 18a and extend laterally or between two steps 12 upwards.

Furthermore, one or more stop elements (not shown) could be provided on the step-over device 15 or on the entry unit 4 in order to

To limit the movement of the climbing device 15 beyond the ready position BP (here from the vertical to the left). This can cause the

Climbing device 15 can be reduced in the ready position BP, whereby the crossing can be made easier and safety can be increased. For example, one or more stop elements in the form of rubber buffers could be provided on the step-over device 15 or here the ladder (at the upper end in the ready position BP), which in the ready position BP with the lower end of the longitudinal member 11 or with the lowermost cross member 30 in Contact are. Of course, the stop elements could alternatively or additionally also be provided on the longitudinal beam 11 or on the lowermost cross beam 30 in order to limit the movement of the ladder.

In order to further restrict vibrations of the step-over device 15 in the ready position BP, a separate locking device (not shown) can also be provided which fixes the step-over device 15 in the ready position BP. As a result, the movement of the step-over device 15 can be minimized, for example, left and right out of the vertical in FIG. 4, which further increases safety when stepping over can be increased. The locking device can, for example, be designed similarly to the locking unit 18. An advantage of the second embodiment (FIG. 4) of the step-over device 15 over the first embodiment (FIGS. 1-3b) is, for example, that due to the arrangement of the step-over device 15 along the side member 11 in the rest position RP a longer step-over device 15 can be used, whereby the step-over from / to the cable car 7 can be facilitated.

In Figure 5a, the step-over device 15 and the locking unit 18 from Figure 3 are shown in detail. The step-over device 15 is designed in the form of a ladder and has the fastening unit 21 at one end for pivotable fastening to the

Entry unit 4 on. The fastening unit 21 here comprises a plate 21a which is firmly connected to the ladder, e.g. screwed, welded, riveted, etc. On the upper surface of the plate 21a facing away from the ladder, two eyelets 21b are arranged, which are provided for pivoting attachment to the cross member 30 of the lowest step 12, which is designed as a tube, as already shown in FIG was explained. The eyelets 21b can be attached, for example, by inserting the ends of the eyelets 21b through suitable openings in the plate 21a and attaching them to the lower surface of the plate 21a facing the ladder, e.g. be screwed. This provides a simple way of assembling the climbing device 15 by first arranging the eyelets 21b on the cross member 30 and then passing the ends of the eyelets through the openings in the plate 21a and screwing them to them. Of course, this specific embodiment of the fastening unit 21 is only to be understood as an example and other fastening options would also be conceivable, for example one

Fastening unit 21 in the form of a console, similar to that shown in the first embodiment. The fastening unit 21 could for example also have only two bolts or screws on the side of the step-over device 15, via which the

Climbing device 15 is articulated to the entry unit 4.

On the lower surface of the plate 21a (opposite the eyelets 21b) is part of the

Actuating unit 19 a first lever element 24a is provided. The first lever element 24a acts via an actuating means 31 such as e.g. a cable pull or a flexible shaft together with the locking unit 18 in order to actuate the locking unit 18 to release the locking of the climbing device 15. The locking unit 18 is arranged on the entry unit 4 (see Figure 3) and has a locking element 18a which can be pivoted relative to the entry unit 4 in order to lock the

Climbing device 15 to solve. The locking element 18a can be directly articulated to the entry unit 4 or a part thereof (for example a cross member 30) or, as shown, to a suitable support element 32, which in turn is firmly connected to the entry unit 4. The locking element 18a has an opening 33, which in the rest position RP is in engagement with the step-over device 15 in order to lock the step-over device 15 on the entry unit 4. In the case of a ladder, for example, a rung 16 of the ladder can be brought into engagement with the opening 33.

To release the lock, the locking unit 18 can be actuated from the cable car 7 via the first lever element 24a. As a result, the locking element 18a is pivoted by means of the actuating means 31 from a locking position VP into a release position LP, whereby the step-over device 15 is released and from the

Rest position RP can be shifted to the ready position BP. The axis of rotation of the locking element 18a here runs in the transverse direction, essentially parallel to the cross members 30. The displacement is preferably carried out automatically by gravity, with the movement optionally being able to be braked by an optional braking device.

The locking unit 18 preferably has at least one suitable (not

shown) biasing element 26 to the locking element 18a in the

Preload locking position VP. A suitable mechanical spring is preferably used as the biasing element 26. For example, a torsion spring can be provided in the axis of rotation of the locking element 18a. In addition, in the example shown, it can be advantageous if the first lever element 24a also has a suitable prestressing element 26 in order to enable the first lever element 24a, including the actuating means 31, to be returned to the starting position. The resetting of the first lever element 24a and the actuating means 31 can be carried out with a sufficiently large

Biasing force for example also take place only through the biasing element 26, in particular the spring on the locking element 18a. In the case of an electrically actuatable locking unit 18, instead of the lever element 24a, for example, a switch could be provided or the switch could be actuated by means of the lever element 24a. The switch could then e.g. be connected to the locking unit 18 via an electrical line.

The transfer of the step-over device 15 from the ready position BP (Fig. 4) to the rest position RP is preferably carried out manually, using suitable aids such as e.g. a cable, one or more straps, handles, etc. can be provided. In order to enable the transfer device 15 to be easily moved back and locked in the rest position RP, the locking element 18a in the example shown has a wedge-shaped section to form an inclined surface 34. If the

Climbing device 15 is moved back from the ready position BP to the rest position RP, the climbing-over device 15, here the last rung 16 of the ladder, comes into contact with the inclined surface 34 of the locking element 18a (located in the locking position VP). Due to the well-known wedge effect, the

Locking element 18a of the rung 16 partially in the direction of the release position LP pivoted until the rung 16 engages with the opening 33. By the

Biasing element 26 (such as a torsion spring in the axis of rotation of the locking element 18a), the locking element 18a is moved back into the locking position VP, whereby the step-over device 15 is locked.

As already shown on the basis of the first embodiment, one or more limiting elements 28 (not shown) can be provided on the step-over device 15 and / or the entry unit 4 in order to limit a movement of the step-over device 15 beyond the rest position RP. In addition, a given play between rung 16 and opening 33 can thereby be minimized in order to reduce any rattling noises due to the movement of the step-over device 15 within the opening 33.

Of course, a sensor element 29 can also be provided in the second exemplary embodiment in order to detect the position of the step-over device 15. The function is analogous to that of the first exemplary embodiment, which is why it will not be discussed in more detail at this point.

Fig. 5b shows an alternative embodiment of a locking unit 18. Die

The locking unit has a carrier element 32 which is fastened to the entry unit 4 (not shown). Two locking units 18a are provided on the carrier element 32, which are configured essentially analogously to FIG. 5a. In contrast to the embodiment according to FIG. 5a, the two locking elements 18a in FIG. 5b are each pivotable about an axis of rotation, which extend essentially parallel to the longitudinal support 11 of the entry unit 4 and not in the transverse direction as in FIG. 5a. The

Locking elements 18a each have an opening 33, which with the

The step-over device 15 can be brought into engagement in order to lock the step-over device 15 in the rest position RP on the entry unit 4. However, the openings 33 act here with the longitudinal members 15a of the conductors

Climbing device 15 together and not as before with a rung 16 of the ladder. The function with regard to the actuation by means of an actuating element 19 (not shown) does not, however, differ from the variant according to FIG. 5a, which is why it will no longer be discussed in detail. The double locking means the stability of the

Climbing device 15 can be improved in the rest position RP.

According to a further embodiment (not shown), the step-over device 15, preferably in the form of a ladder, is arranged laterally on the outside of the railing 13 in the rest position RP, that is to say on the side of the railing 13 that faces away from the steps 12. The fastening unit 21 is, for example, a bracket that is pivotably fastened to the entry unit 4, the pivot axis running in the transverse direction, for example parallel to the cross members 30. The step-over device 15 is displaceable relative to the fastening unit 21, for example within a suitable one Recess in the fastening unit 21. The step-over device 15 can thus be moved to and fro within the recess of the fastening unit 21 between two positions in which the two axial ends of the step-over device 15 rest against the fastening unit 21. Advantageously, a guide unit is additionally provided on the railing 1 in order to hold the device 15 securely on the railing 13 in the rest position.

To move into the ready position BP, the step-over device 15, starting from the rest position RP, can first be moved, in particular displaced, relative to the railing 13 and essentially parallel to the railing 13. The

The step-over device 15 is also displaced relative to the fastening unit 21, for example within the recess. The shift is carried out until the first axial end facing away from the fastening unit 21 in the rest position RP

Climbing device 15 which has reached the fastening unit 21 and preferably rests against it. Thereafter, the fastening unit 21 is pivoted, whereby the

Staging position BP is reached.

Finally, it should be noted again that the embodiments described are only to be understood as examples and not restrictive. Besides the ones shown

Embodiments would of course also be conceivable, which are at the discretion of the person skilled in the art. For example, a person skilled in the art can adapt the invention to the specific circumstances of a cable car, such as to different forms of access units.
