Definitions

  • the present invention relates to a rail vehicle which is supported on rails so that it can roll by means of a wheel train.
  • this can be a locomotive or a railcar.
  • Such rail vehicles are equipped with a driver's cab in which control consoles for the train or vehicle driver are installed.
  • a driver's cab often has a separate entry and exit option, with a vehicle wall of the vehicle body being able to be walked through by means of a door.
  • an extendable ladder and a vehicle with an extendable ladder are disclosed.
  • This has an end section facing a floor, which comprises at least one extendable rung.
  • this extendable rung is in a position facing the ground, so that the vehicle driver can climb into the rail vehicle using this rung.
  • a pneumatic pressure cylinder and a gas spring that counteracts this are installed in this ladder device, so that the extendable rung of the ladder device can be extended using compressed air, and retraction is ensured by the restoring force of the gas spring.
  • the extendable ladder is connected to the vehicle's existing compressed air system.
  • One object of the present invention is therefore to specify an improved rail vehicle with an boarding device, the boarding device having a simple and robust structure and being characterized in particular by high reliability and positive ergonomics in use.
  • the rail vehicle is formed, among other things, by a vehicle body and a wheel train, as a result of which the rail vehicle is mounted on rails so that it can roll. Furthermore, the rail vehicle or the vehicle body of the rail vehicle an entry area and an entry device arranged thereon, making it possible to get into an interior of the vehicle body.
  • the entry area can be formed together with a door device.
  • the boarding area is arranged on a platform-like section of the rail vehicle, it being possible to enter the interior of the vehicle body from this platform-like section, for example through a door device.
  • this is access exclusively for a train driver and/or for personnel on the rail vehicle.
  • the boarding device is not suitable and/or intended to allow passengers who use the rail vehicle for passenger transport to board and alight between a platform and the passenger compartment of the rail vehicle in normal use.
  • the entry device is arranged in the immediate vicinity of the entry area and has a lower step, a guide device, a restoring element and a damping element.
  • the entry area can be designed as a door sill and/or the lower door edge of a door device.
  • the entry device is arranged in the vicinity of the door device in such a way that a person using the entry device can directly grip and operate the door device and ultimately move through the door device.
  • the lower step of the boarding device is arranged displaceably on the boarding area by means of the guide device, wherein the translation of the lower step can take place in a vertical direction between an upper position and a lower position.
  • the term "vertical direction" is always to be understood in connection with the operating position of the rail vehicle.
  • the restoring element and the damping element are arranged between the lower step and the entry area such that the lower step can be brought from the lower position to the upper position by a restoring force provided by the restoring element during a restoring movement.
  • the damping element generates a damping force that can counteract the restoring force.
  • the arrangement of the restoring element of the described entry device of the rail vehicle has the effect that the lower step is basically in the upper position. If a person, for example the vehicle driver, wants to get into the rail vehicle, the person would manually move the lower step from the upper position to the lower position.
  • the entry device is designed in such a way that the lower step is arranged in the lower position so close to the ground that the distance between the ground and the lower step can be overcome by a normal-sized, healthy person.
  • all vertically displaceable parts, for example the lower step are held in the retracted position by the spring preload, with the damping element effectively preventing the damping element from springing back from the lower position to the upper position.
  • the restoring element and the damping element are designed in such a way that the restoring movement of the lower step is slow and/or delayed so that the person can easily climb onto the lower step immediately after it has been extended or pulled out.
  • the speed of the restoring movement in particular the force ratio of damping force and restoring force, is selected so that the person is able to step onto the step with one foot before it moves too far away from the ground during the course of the restoring movement. If the lower step is in the lower position and at the same time is subject to part of the weight of a person's foot, it remains in the lower position.
  • the restoring element can be designed in such a way that the weight force required to hold the lower step in the lower position is at most 50 N, preferably at most 40 N, in particular at most 30 N.
  • the maximum restoring force is between 10 N and 100 N, preferably 15 N and 75 N, particularly preferably 20 N and 30 N.
  • the restoring force can also take into account the weight of the lower tread device, if any components that are permanently connected to it. This is particularly useful when the mass of the lower treadle acts against the restoring force. This is the case with a displacement direction of the lower tread device exclusively in the vertical direction.
  • the damping element is designed such that its damping constant has a value between 5 kg/s and 80 kg/s, preferably between 10 kg/s and 50 kg/s, and particularly preferably between 15 kg/s and 20 kg/s .
  • the boarding device is designed as a telescoping ladder arrangement with at least one spar running transversely to the vertical direction.
  • the ladder arrangement or the stile is made up, among other things, of a fixed part and an extendable part that is slidably arranged thereon and thus form the guide device.
  • the fixed part is fastened to the entry area and is arranged such that it can be moved.
  • the pull-out part carries the lower step and/or is formed integrally with it.
  • the guide device can be partially integrated into the vehicle body, for example the fixed part of the ladder arrangement or the rail. This would be conceivable, in that the lower step would be guided in the vertical direction directly in a rail provided in the vehicle body. In this case, said guide device would be formed by the rail and by a part of the step that engages in the rail.
  • the entry device has an upper step.
  • this can be arranged essentially at the location of the upper position of the lower step. Consequently, the lower step is in the up position and the upper step is in substantially the same position. If the lower step is in the lower position, it is spaced apart from the upper step in the vertical displacement direction, with the upper step and the lower step forming two rungs of the ladder-like entry device in terms of their function.
  • the upper step can be designed with a receptacle that has a shape that corresponds to the lower step.
  • the lower step can be accommodated essentially completely in the receptacle of the upper step.
  • the upper step has a box-shaped receptacle which opens downwards - for example similar to the lid of a shoebox - and that the lower step shows a similar, smaller box-shaped form. Due to the smaller shape of the lower step in relation to the upper step, it can be accommodated at least partially, preferably completely, in its underside.
  • damping element and the restoring element can be arranged within the guide device, in particular the spar. This achieves a compact size.
  • the damping element and restoring element are provided parallel or coaxially to one another with respect to their longitudinal axes on the guide device, in particular on or in the spar.
  • the ladder device is provided with two bars arranged in parallel, with the upper step being provided on the fixed parts of the bars and the lower step on the extendable part in the bars, the ladder device has two rungs, one rung opposite the other rung is slidably provided.
  • the boarding device has at least one additional auxiliary step, which is firmly arranged on the extension part of the ladder device.
  • the auxiliary step is also moved in the vertical direction.
  • the entry device can comprise a further fixed step which is arranged in the vertical direction above the upper step.
  • a distance in the vertical direction between the step located in the lower position and the upper step can be essentially equal to the distance between the upper step and the fixed further step lying above it in the vertical direction.
  • the boarding device forms a ladder device with essentially three equally spaced rungs.
  • the auxiliary step and the further fixed step can be designed and arranged on the entry device such that the auxiliary step is in the upper position in the vertical direction essentially at the same level as the further fixed step.
  • the auxiliary step can be extended vertically against the restoring movement in the extension direction by partially applying weight to the auxiliary step. If the pull-out part with the auxiliary step and lower step is fully extended, the auxiliary step and/or the lower step can be used as additional support for one foot.
  • the auxiliary step like the lower step, is a movable rung.
  • auxiliary step either completely or partially as a step and / or with a handle or as a In this way, a person who wants to get on can pull out the lower step from the upper position to the lower position by pulling the handle of the auxiliary step.
  • the rail vehicle or the boarding device comprises a latching device, with which the lower step can be fixed in the lower and/or in the upper position.
  • This locking aid makes it possible for the lower step to be permanently in the lower and/or upper position, so that the lower step does not have to be actuated every time, for example when getting in and out of the vehicle several times.
  • the latching device can have a release mechanism for releasing this latching device.
  • a release mechanism with a trigger is to be designed in such a way that the latch can be opened by a human footstep and/or by manual actuation of the trigger.
  • the trigger could be advantageously arranged in such a way that it can be actuated when the person boarding is standing on the upper step and/or on the other fixed step.
  • the locking device can be released in that the lower step is briefly relieved, loaded and then relieved again in the course of 'stepping' or 'kicking'. This means that while the person boarding is already supporting a significant part of their body weight with one leg on the upper step or possibly on the further fixed step, the release mechanism of the locking device can be released with the other leg by stepping on the lower step again or possibly on the auxiliary step be actuated. The lower step is thus retracted when the person boarding has already reached the boarding area of the rail vehicle.
  • Boarding the rail vehicle can thus take place as follows: the person wishing to board approaches the rail vehicle, for example being on the track bed next to the rails or on a low boarding platform.
  • the lower step of the entry device is either in the upper position or is already held in the lower position by the locking device.
  • the person grips an area of the displaceable part of the entry device, for example the lower step, the pull-out part and/or the auxiliary step, and causes the lower step to extend by pulling accordingly.
  • the latching device is provided with a snapping mechanism so that the lower step automatically latches once it has reached the lower position.
  • the entry device comprises a holding device, with which the lower step can be fixed in the upper position.
  • the lower step can be fixed in the upper position.
  • the entry device is provided with a sensor element for detecting a position of the lower step.
  • the lower step can be prevented from being in the lower position in an undesired manner.
  • a warning signal can be output when the rail vehicle is set in motion but the lower step has not yet been retracted.
  • a limit switch in particular with an integrated mechanical lock, can be provided for this purpose,
  • the rail vehicle can be equipped with a lighting device in the area of the boarding device, so that it can be safely used even when visibility is poor.
  • the lighting device can be coupled to a limit switch, so that the boarding area is always illuminated when the boarding device is extended.
  • a part of an exemplary rail vehicle 1 is shown, this being a control car of a push-pull train or multiple unit.
  • a rail vehicle 1 has a vehicle body 4 which is mounted on a wheel train 3 on rails 2 such that it can roll.
  • the rail vehicle 1 is in a vertical direction 7 above the rails 2. The vertical direction 7 is thus based on the operating position of the rail vehicle 1.

  • the boarding area 6 is located directly on a door sill of the door device 9.
  • Handrails 28 can be provided to the right and left in the transverse direction 8 next to the door device 9 to support boarding.
  • the actual entry device 10 is the Figures 2 to 4 arranged at the boarding area 6 of the rail vehicle 1 reproduced in detail.
  • the boarding device 10 is composed, among other things, of two lateral bars 17 and 18 running substantially in the vertical direction 7, a lower step 13, an upper step 12 and another fixed step 22 arranged above it.

  • the lower step 13 is firmly connected to the Pull-out parts 20, which thus together with the lower step 13 together have a U-shape.
  • an auxiliary step 21 is provided on the pull-out parts 20 in the vertical direction 7 above the lower step 13 .
  • the spars 20, the lower step 13 and the auxiliary steps 21 are thus formed fixed to each other and form a rigid unit.
