Description

Technisches Gebiettechnical field

Die vorliegende Erfindung betrifft ein Schienenfahrzeug, welches mithilfe eines Räderwerks auf Schienen rollbar abgestützt ist. Beispielsweise kann es sich dabei um eine Lokomotive oder um einen Triebwagen handeln. Solche Schienenfahrzeuge sind mit einem Führerstand ausgestattet, in welchem Steuerungskonsolen für den Zug- oder Fahrzeugführer installiert sind. Oftmals verfügt ein solcher Führerstand über eine separate Einstiegs- und Ausstiegsmöglichkeit, wobei eine Fahrzeugwand des Fahrzeugkörpers mittels einer Tür durchschritten werden kann.The present invention relates to a rail vehicle which is supported on rails so that it can roll by means of a wheel train. For example, 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. Such 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.

Vorbekannter Stand der TechnikKnown prior art

Es zeigt sich, dass solche Einstiegstüren deutlich oberhalb des Schienenniveaus im Fahrzeugkörper angeordnet sind. Um es einem Fahrzeugführer zu ermöglichen, auch ohne einen vorhandenen Bahnsteig die Einstiegstür erreichen zu können, umfassen viele solcher Schienenfahrzeuge in der Außenwand des Fahrzeugkörpers eine Art Leitervorrichtung. Auf diesem Wege kann der Fahrzeugführer den Höhenunterschied zwischen dem Boden bzw. Schienenniveau und Einstiegstür überwinden und in den Führerstand gelangen.It turns out that such entrance doors are arranged well above the level of the rails in the vehicle body. In order to enable a vehicle driver to be able to reach the entrance door even without an existing platform, many such rail vehicles include a type of ladder device in the outer wall of the vehicle body. In this way, the vehicle driver can overcome the difference in height between the floor or rail level and the entrance door and get into the driver's cab.

Es ist im Allgemeinen bekannt, dass diese Leitervorrichtungen unter Umständen das sogenannte Lichtraumprofil des Schienenfahrzeugs überragen. Somit kann es notwendig sein, ein Einklappen oder Zurückziehen einer solchen Leitervorrichtung zu vorzusehen.It is generally known that these ladder devices may protrude beyond what is known as the structure gauge of the rail vehicle. Thus, it may be necessary to provide for folding or retraction of such a ladder device.

In der deutschen Offenlegungsschrift DE 10 2012 213 181 A1 wird in diesem Zusammenhang eine ausfahrbare Leiter und ein Fahrzeug mit einer ausfahrbaren Leiter offenbart. Diese weist einen einem Boden zugewandten Endabschnitt auf, welcher mindestens eine ausfahrbare Sprosse umfasst. Im ausgefahrenen Zustand ist diese ausfahrbare Sprosse in einer dem Boden zugewandten Position, sodass der Fahrzeugführer mittels dieser Sprosse in das Schienenfahrzeug einsteigen kann. Weiterhin ist in dieser Leitervorrichtung ein pneumatischer Druckzylinder und eine diesem entgegenwirkende Gasfeder verbaut, sodass die ausfahrbare Sprosse der Leitervorrichtung mithilfe von Druckluft ausgefahren werden kann, und ein Einfahren von der Rückstellkraft der Gasfeder gewährleistet wird. Dabei wird die ausfahrbare Leiter an das vorhandene Druckluftsystem des Fahrzeugs angeschlossen. In der DE 10 2012 104 987 A1 wird ein Außentritt mit einer Trittstufe für den Führerstand von Schienenfahrzeugen offenbart, mit welchem auch das Ein- und Aussteigen bei unter Bahnsteighöhe liegendem Terrain, zum Beispiel dem Gleisbett, bequem möglich ist. Durch das Eigengewicht der Trittstufe wird diese selbständig nach unten ausgefahren. Die Ausfahrbewegung wird dabei durch die Wirkung eines Zugdämpfers gedämpft. Zum Einfahren der Trittstufe vom Führerstand aus wird ein oberer Handgriff soweit nach oben gezogen, bis beide Handgriffe in eine Arretierausnehmung verschwenkt werden können. Soll das Einfahren der Trittstufe von außen erfolgen, was auch bei geschlossener Führerstandtür möglich ist, wird die Trittstufe manuell bis in ihre obere Endstellung angehoben.In the German Offenlegungsschrift DE 10 2012 213 181 A1 in this context, 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. In the extended state, this extendable rung is in a position facing the ground, so that the vehicle driver can climb into the rail vehicle using this rung. Furthermore, 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. In the DE 10 2012 104 987 A1 discloses an outside step with a step for the driver's cab of rail vehicles, with which boarding and alighting on terrain that is below platform height, for example the track bed, is easily possible. The step's own weight automatically extends it downwards. The extension movement is dampened by the action of a tension damper. To retract the step from the driver's cab, an upper handle is pulled up until both handles can be pivoted into a locking recess. If the step is to be retracted from the outside, which is also possible when the driver's cab door is closed, the step is raised manually to its upper end position.

Nachteile des Standes der TechnikDisadvantages of the Prior Art

Die bisher bekannten Konzepte solcher Schienenfahrzeuge mit entsprechenden Einstiegshilfen sind jedoch entweder sehr komplex aufgebaut, schlecht zu bedienen und/oder fehleranfällig.However, the previously known concepts of such rail vehicles with corresponding boarding aids either have a very complex structure, are difficult to operate and/or are prone to errors.

Problemstellungproblem

Eine Aufgabe der vorliegenden Erfindung ist es daher, ein verbessertes Schienenfahrzeug mit einer Einstiegsvorrichtung anzugeben, wobei die Einstiegsvorrichtung einen einfachen und robusten Aufbau aufweist und sich insbesondere im Einsatz durch hohe Zuverlässigkeit und positive Ergonomie auszeichnet.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.

Erfindungsgemäße LösungSolution according to the invention

Die obige Aufgabe wird durch ein Schienenfahrzeug nach Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The above object is achieved by a rail vehicle according to claim 1. Advantageous configurations of the invention result from the dependent claims.

Das Schienenfahrzeug ist unter anderem durch ein Fahrzeugkörper und ein Räderwerk gebildet, wodurch das Schienenfahrzeug rollbar auf Schienen gelagert ist. Weiterhin weist das Schienenfahrzeug bzw. der Fahrzeugkörper des Schienenfahrzeugs einen Einstiegsbereich und eine daran angeordnete Einstiegsvorrichtung auf, wodurch es ermöglicht wird, in einen Innenraum des Fahrzeugkörpers zu gelangen. Der Einstiegsbereich kann dabei zusammen mit einer Türvorrichtung gebildet sein. Denkbar ist jedoch auch, dass der Einstiegsbereich an einem plattformähnlichen Abschnitt des Schienenfahrzeugs angeordnet ist, wobei man von diesem plattformähnlichen Abschnitt, beispielsweise durch eine Türvorrichtung, in den Innenraum des Fahrzeugkörpers eintreten kann.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. However, it is also conceivable that 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.

Insbesondere handelt es sich hierbei um einen Zugang ausschließlich für einen Zugführer und/oder für Personal des Schienenfahrzeugs. D.h. die Einstiegsvorrichtung ist nicht dazu geeignet und/oder dazu vorgesehen, Fahrgäste, die das Schienenfahrzeug zum Personentransport benutzen, im gewöhnlichen Gebrauchsfall ein Einsteigen und Aussteigen zwischen einem Bahnsteig und dem Fahrgastraum des Schienenfahrzeugs zu ermöglichen.In particular, this is access exclusively for a train driver and/or for personnel on the rail vehicle. I.e. 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.

Die Einstiegsvorrichtung ist dabei in unmittelbarer Wirknähe an dem Einstiegsbereich angeordnet und weist eine untere Trittstufe, eine Führungsvorrichtung, ein Rückstellelement und ein Dämpfungselement auf. Insbesondere kann der Einstiegsbereich als Türschwelle und/oder untere Türkante einer Türvorrichtung ausgebildet sein. Die Einstiegsvorrichtung ist dabei derart in der Nähe der Türvorrichtung angeordnet, dass eine die Einstiegsvorrichtung benutzende Person unmittelbar die Türvorrichtung ergreifen und betätigen, und letztendlich sich durch die Türvorrichtung hindurch bewegen kann.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. In particular, 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.

Die untere Trittstufe der Einstiegsvorrichtung ist mittels der Führungsvorrichtung verschiebbar am Einstiegsbereich angeordnet, wobei die Translation der unteren Trittstufe in einer Vertikalrichtung zwischen einer oberen Position und einer unteren Position stattfinden kann.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.

Der Begriff "Vertikalrichtung" ist im Kontext der Erfindung und der Beschreibung der Ausführungsbeispiele immer im Zusammenhang der Einsatzposition des Schienenfahrzeugs zu verstehen. Insbesondere bedeutet dies, dass die untere Trittstufe in unterer Position näher am Boden und in oberer Position näher am Einstiegsbereich positioniert ist.In the context of the invention and the description of the exemplary embodiments, the term "vertical direction" is always to be understood in connection with the operating position of the rail vehicle. In particular, this means that the lower step is positioned closer to the ground when in the lower position and closer to the boarding area when in the upper position.

Erfindungsgemäß sind das Rückstellelement und das Dämpfungselement so zwischen der unteren Trittstufe und dem Einstiegsbereich angeordnet, dass die untere Trittstufe durch eine vom Rückstellelement bereitgestellte Rückstellkraft im Zuge einer Rückstellbewegung aus der unteren Position in die obere Position gebracht werden kann. Gleichzeitig wird mit Hilfe des Dämpfungselements eine Dämpfungskraft erzeugt, die der Rückstellkraft entgegenwirken kann.According to the invention, 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. At the same time, the damping element generates a damping force that can counteract the restoring force.

Auf diese Weise wird ermöglicht, dass zum Beispiel ein Fahrzeugführer in einfacher Art und Weise das Schienenfahrzeug besteigen kann, wenn die untere Trittstufe in unterer Position ist. Denn auf diese Weise ist es erstmalig möglich, einen übermäßigen Abstand zwischen Einstiegsbereich und Boden in einfacher Weise mithilfe der Einstiegsvorrichtung ohne externe Einstiegshilfen zu überwinden, zum Beispiel wenn das Schienenfahrzeug in einem Bereich ohne Bahnsteig oder weitere Einstiegshilfen abgestellt ist. Dadurch wird die Bedienbarkeit durch den Fahrzeugführer wesentlich verbessert.In this way it is made possible that, for example, a vehicle driver can easily climb onto the rail vehicle when the lower step is in the lower position. Because in this way it is possible for the first time to overcome an excessive distance between the boarding area and the ground in a simple manner using the boarding device without external boarding aids, for example if the rail vehicle is parked in an area without a platform or other boarding aids. This significantly improves the usability by the vehicle driver.

Insbesondere bewirkt die die Anordnung des Rückstellelements der beschriebenen Einstiegsvorrichtung des Schienenfahrzeugs, dass die untere Trittstufe sich grundsätzlich in der oberen Position befindet. Will eine Person, zum Beispiel der Fahrzeugführer, in das Schienenfahrzeug einsteigen, so würde die Person die untere Trittstufe manuell aus der oberen Position in die untere Position bewegen. Insbesondere ist die Einstiegsvorrichtung so ausgebildet, dass die untere Trittstufe in untere Position derart nahe am Boden angeordnet ist, dass der Abstand zwischen Boden und untere Trittstufe durch einen normal großen, gesunden Menschen überwindet werden kann. Insbesondere werden sämtliche vertikal verschiebbaren Teile, zum Beispiel die untere Trittstufe, durch die Federvorspannung in der eingefahrenen Position gehalten, wobei ein Zurückschnellen aus der unteren Position in die obere Position durch das Dämpfungselement effektiv verhindert wird.In particular, 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. In particular, 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. In particular, 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.

Gemäß einer Ausgestaltung der Erfindung sind das Rückstellelement und das Dämpfungselement derart ausgebildet, dass die Rückstellbewegung der unteren Trittstufe derart langsam und/oder verzögert erfolgt, sodass ein Besteigen der unteren Trittstufe durch die Person unmittelbar nach dem Ausfahren bzw. Ausziehen ohne Weiteres möglich ist. Im Speziellen ist die Geschwindigkeit der Rückstellbewegung, insbesondere das Kräfteverhältnis von Dämpfungskraft und Rückstellkraft, so gewählt, dass es der Person ermöglicht wird, die Trittstufe mit einem Fuß zu betreten bevor sich diese im Zuge der Rückstellbewegung zu weit vom Boden entfernt. Ist die untere Trittstufe in der unteren Position und gleichzeitig durch einen Teil einer Gewichtskraft eines Fußes der Personen belastet, so verbleibt diese in der unteren Position. Insbesondere kann das Rückstellelement so ausgebildet sein, dass die notwendige Gewichtskraft zum Halten der unteren Trittstufe in untere Position maximal 50 N, bevorzugt maximal 40 N, insbesondere maximal 30 N beträgt.According to one embodiment of the invention, 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. In particular, 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. In particular, 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.

In Erweiterung dieses Grundprinzips wird erfindungsgemäß vorgeschlagen, das Rückstellelement derart zu dimensionieren, sodass es einem normal großen und gesunden Menschen möglich ist, die untere Trittstufe aus der oberen Position in die untere Position zu verbringen, indem die Rückstellkraft durch die Person manuell überwunden wird.In an extension of this basic principle, it is proposed according to the invention to dimension the return element in such a way that it can accommodate a normal-sized and It is possible for healthy people to move the lower step from the upper position to the lower position by manually overcoming the restoring force by the person.

Gemäß einer speziellen Ausführungsform beträgt die maximale Rückstellkraft zwischen 10 N und 100 N, bevorzugt 15 N und 75 N, besonders bevorzugt 20 N und 30 N. Insbesondere kann die Rückstellkraft hierbei auch die Gewichtskraft der unteren Trittvorrichtung gegebenenfalls damit fest verbundener Komponenten berücksichtigen. Dies ist insbesondere sinnvoll, wenn die Masse der unteren Trittvorrichtung entgegen der Rückstellkraft wirkt. Dies ist bei einer Verschiebungsrichtung der unteren Trittvorrichtung ausschließlich in vertikaler Richtung der Fall.According to a special embodiment, the maximum restoring force is between 10 N and 100 N, preferably 15 N and 75 N, particularly preferably 20 N and 30 N. In particular, 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.

Insbesondere ist das Dämpfungselement so ausgestaltet, dass dessen Dämpfungskonstante einen Wert zwischen 5 kg/s und 80 kg/s innehat, bevorzugt zwischen 10 kg/s und 50 kg/s, und besonders bevorzugt zwischen 15 kg/s und 20 kg/s beträgt.In particular, 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 .

Im Sinne einer Weiterentwicklung wird angeführt, dass die Einstiegsvorrichtung als eine teleskopierbare Leiteranordnung mit mindestens einem quer zur Vertikalrichtung verlaufenden Holm ausgestaltet ist. Die Leiteranordnung bzw. der Holm setzt sich unter anderem aus einem Festteil und aus einem daran verschiebbar angeordneten Ausziehteil zusammen und bilden somit die Führungsvorrichtung. Das Festteil ist dabei am Einstiegsbereich befestigt und diesbezüglich und verschiebbar angeordnet. Das Ausziehteil trägt die untere Trittstufe und/oder ist damit integral ausgebildet.In terms of a further development, it is stated that 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.

Gemäß einer Ausführungsform kann die Führungsvorrichtung teilweise, zum Beispiel der Festteil der Leiteranordnung oder des Holms, integriert im Fahrzeugkörper ausgebildet sein. Denkbar wäre dies, indem die untere Trittstufe direkt in einer im Fahrzeugkörper vorgesehenen Schiene in Vertikalrichtung geführt wäre. Die besagte Führungsvorrichtung würde in diesem Fall durch die Schiene und durch einen in die Schiene eingreifenden Teil der Trittstufe gebildet werden.According to one embodiment, 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.

Im Zuge einer weiteren Ausführungsform wird offenbart, dass die Einstiegsvorrichtung eine obere Trittstufe aufweist. Besondere kann diese im Wesentlichen an dem Ort der oberen Position der unteren Trittstufe angeordnet sein. Folglich befinden sich die untere Trittstufe in oberer Position und die obere Trittstufe im Wesentlichen an derselben Position. Ist die untere Trittstufe in unterer Position, so ist sie gegenüber der oberen Trittstufe in vertikaler Verschieberichtung beabstandet, wobei die obere Trittstufe und die untere Trittstufe hinsichtlich ihrer Funktion zwei Sprossen der leiterartigen Einstiegsvorrichtung formen.In the course of a further embodiment it is disclosed that the entry device has an upper step. In particular, 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.

Gemäß einer besonderen Ausgestaltung kann die obere Trittstufe mit einer Aufnahme ausgestaltet sein, die eine mit der unteren Trittstufe korrespondierende Form aufweist. Insbesondere kann die untere Trittstufe in der Aufnahme der oberen Trittstufe im Wesentlichen vollständig aufgenommen werden. Dies hat zur Folge, dass die sich in oberer Position befindliche untere Trittstufe in der Aufnahme der oberen Trittstufe verschwindet, wodurch der Windwiderstand der einzelnen Komponenten und eine Verletzungsgefahr daran reduziert und eine erhöhte strukturell-visuelle Homogenität erzeugt wird.According to a particular embodiment, the upper step can be designed with a receptacle that has a shape that corresponds to the lower step. In particular, the lower step can be accommodated essentially completely in the receptacle of the upper step. As a result, the lower step, which is in the upper position, disappears into the seat of the upper step, reducing the wind resistance of the individual components and the risk of injury thereto and creating increased structural-visual homogeneity.

Denkbar ist zum Beispiel, dass die obere Trittstufe einen nach unten geöffnete, kastenförmige Aufnahme aufweist - beispielsweise ähnlich einem Deckel eines Schuhkartons -, und dass die untere Trittstufe eine ähnliche, kleinere kastenförmige Form zeig. Aufgrund der im Verhältnis zur oberen Trittstufe kleineren Form der unteren Trittstufe kann diese in deren Unterseite zumindest teilweise, bevorzugt vollständig, aufgenommen werden kann.It is conceivable, for example, that 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.

Weiterhin können das Dämpfungselement und das Rückstellelement innerhalb der Führungsvorrichtung, insbesondere des Holms, angeordnet sein. Dadurch wird eine kompakte Baugröße erzielt.Furthermore, the damping element and the restoring element can be arranged within the guide device, in particular the spar. This achieves a compact size.

Gemäß einer weiteren Ausführungsform sind Dämpfungselement und Rückstellelement hinsichtlich ihrer Längsachsen parallel oder koaxial zueinander an der Führungsvorrichtung, insbesondere am oder im Holm, vorgesehen.According to a further embodiment, 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.

Wenn die Leitervorrichtung mit zwei parallel angeordneten Holmen versehen ist, wobei die obere Trittstufe jeweils an den Festteilen der Holme, und die untere Trittstufe jeweils an dem Ausziehteil in den Holmen vorgesehen ist, so weist die Leitervorrichtung zwei Sprossen auf, wobei die eine Sprosse gegenüber der anderen Sprosse verschiebbar vorgesehen ist.If 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.

Insbesondere ist es denkbar, in dem ersten Holm das Rückstellelement und im zweiten Holm das Dämpfungselement vorzusehen, und/oder in jedem Holm jeweils ein Rückstellelement und ein Dämpfungselement parallel oder koaxial zueinander anzuordnen.In particular, it is conceivable to provide the restoring element in the first spar and the damping element in the second spar, and/or to arrange a restoring element and a damping element in each spar parallel or coaxially to one another.

Im Zuge einer Weiterentwicklung wird angeführt, dass die Einstiegsvorrichtung mindestens einen zusätzlichen Hilfstritt aufweist, welcher fest am Ausziehteil der Leitervorrichtung angeordnet ist. Somit wird beim Ausfahren und Einziehen der unteren Trittstufe auch der Hilfstritt in Vertikalrichtung mitverschoben. Insbesondere ist es vorteilhaft, den Hilfstritt in Vertikalrichtung über der unteren Trittstufe am Ausziehteil vorzusehen.In the course of a further development, it is stated that the boarding device has at least one additional auxiliary step, which is firmly arranged on the extension part of the ladder device. Thus, when the lower step is extended and retracted, the auxiliary step is also moved in the vertical direction. In particular, it is advantageous to provide the auxiliary step in the vertical direction above the lower step on the pull-out part.

Gemäß einer Weiterentwicklung der Erfindung kann die Einstiegsvorrichtung eine weitere feste Trittstufe umfassen, die in Vertikalrichtung über der oberen Trittstufe angeordnet ist. Insbesondere kann ein Abstand in Vertikalrichtung zwischen der sich in unterer Position befindlicher Trittstufe zur oberen Trittstufe im Wesentlichen gleich dem Abstand zwischen der oberen Trittstufe und der in Vertikalrichtung darüber liegenden festen weiteren Trittstufe sein. Auf diese Weise bildet die Einstiegsvorrichtung eine Leitervorrichtung mit im Wesentlichen drei gleich beabstandeten Sprossen aus.According to a further development of the invention, the entry device can comprise a further fixed step which is arranged in the vertical direction above the upper step. In particular, 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. In this way, the boarding device forms a ladder device with essentially three equally spaced rungs.

Weiterhin können gemäß einer Ausgestaltung der Hilfstritt und die weitere feste Trittstufe an der Einstiegsvorrichtung derart ausgebildet und angeordnet sein, sodass sich der Hilfstritt in oberer Position in Vertikalrichtung im Wesentlichen auf demselben Höhenniveau wie die weitere feste Trittstufe befindet.Furthermore, according to one embodiment, 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.

Dies führte dazu, dass eine aus dem Schienenfahrzeug aussteigende Person mit einem Fuß auf die feste Trittstufe treten und mit dem anderen Fuß den Hilfstritt belasten kann. Auf diese Weise kann die untere Trittstufe durch teilweise Beaufschlagung des Hilfstritts mit Gewichtskraft entgegen der Rückstellbewegung in Ausfahrrichtung vertikal ausgefahren werden. Ist der Ausziehteil mit Hilfstritt und unterer Trittstufe vollständig ausgefahren, so kann der Hilfstritt und/oder die untere Trittstufe als weitere Abstützung für einen Fuß verwendet werden. Der Hilfstritt stellt sich somit, wie auch die untere Trittstufe, als eine verschiebbare Sprosse dar.This meant that a person getting out of the rail vehicle could step on the fixed step with one foot and put the other foot on the auxiliary step. In this way, the lower 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.

Weiterhin ist es auch denkbar, den Hilfstritt entweder vollständig oder teilweise als Trittstufe und/oder mit einem oder als Handgriff auszuführen, wobei eine einsteigewillige Person auf diese Weise die untere Trittstufe durch Ziehen am Handgriff des Hilfstritts aus der oberen Position in die untere Position ausziehen kann.Furthermore, it is also conceivable to perform the 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.

Gemäß einer weiteren Entwicklung der Erfindung umfasst das Schienenfahrzeug bzw. die Einstiegsvorrichtung eine Rastvorrichtung, womit die untere Trittstufe in der unteren und/oder in der oberen Position festgelegt werden kann. Diese Arretierungshilfe ermöglicht es, dass sich die untere Trittstufe permanent in unterer und/oberen Position befindet, und die untere Trittstufe beispielsweise bei mehrmaligem Ein- und Aussteigen nicht jedes Mal betätigt werden muss.According to a further development of the invention, 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.

Entsprechend dazu kann die Rastvorrichtung einen Lösemechanismus zum Lösen dieser Rastvorrichtung aufweisen. Insbesondere ist ein solcher Lösungsmechanismus mit einem Auslöser so auszubilden, dass die Einrastung durch einen menschlichen Fußtritt und/oder durch eine manuelle Betätigung des Auslöser geöffnet werden kann. Günstiger Weise könnte der Auslöser derart angeordnet sein, sodass dieser betätigbar ist, wenn die einsteigende Person auf der oberen Trittstufe und/oder auf der weiteren festen Trittstufe steht.Correspondingly, the latching device can have a release mechanism for releasing this latching device. In particular, such 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.

Weiterhin ist auch denkbar, dass die Rastvorrichtung gelöst werden kann, indem die untere Trittstufe im Zuge eines ,Antretens' oder ,Ankickens', kurz entlastet, belastet und wieder entlastet wird. D.h. während die einsteigende Person einen wesentlichen Teil ihres Körpergewichts mit einem Bein bereits auf der oberen Trittstufe oder gegebenenfalls auf der weiteren festen Trittstufe abstützt, so kann mit dem anderen Bein der Lösemechanismus der Rastvorrichtung durch ein nochmaliges Auftreten auf die untere Trittstufe oder gegebenenfalls auf den Hilfstritt betätigt werden. Somit wird die untere Trittstufe eingefahren, wenn die einsteigende Person den Einstiegsbereich des Schienenfahrzeugs bereits erreicht hat.Furthermore, it is also conceivable that 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.

Ein Einsteigen in das Schienenfahrzeug kann somit wie folgt vonstattengehen: die einsteigewillige Person tritt an das Schienenfahrzeug heran, wobei sich diese beispielsweise auf dem Gleisbett neben den Schienen oder auf einer niedrigen Zustiegsplattform befindet. Die untere Trittstufe der Einstiegsvorrichtung befindet sich dabei entweder in oberer Position oder ist bereits durch die Rastvorrichtung in unterer Position gehalten. In ersterem Fall greift die Person einen Bereich des verschiebbaren Anteils der Einstiegsvorrichtung, beispielsweise die untere Trittstufe, den Ausziehteil und/oder den Hilfstritt, und veranlasst ein Ausfahren der unteren Trittstufe durch ein entsprechendes Ziehen. Gegebenenfalls ist die Rastvorrichtung mit einem einschnappenden Mechanismus versehen, sodass die untere Trittstufe automatisch einrastet, sobald diese die untere Position erreicht hat. Nun betritt die Person die untere Trittstufe und steigt durch Benutzen der oberen Trittstufe und gegebenenfalls der weiteren festen Trittstufe auf das Schienenfahrzeug. Gegebenenfalls kann dann der Auslöser des Lösemechanismus' der Rastvorrichtung betätigt werden, sodass die untere Trittstufe aufgrund der Rückstellkraft aus der unteren Position in die obere Position eingefahren wird.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. In the first case, 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. Where applicable, the latching device is provided with a snapping mechanism so that the lower step automatically latches once it has reached the lower position. The person now steps onto the lower step and climbs onto the rail vehicle by using the upper step and, if necessary, the other fixed step. If necessary, the trigger of the release mechanism of the locking device can then be actuated, so that the lower step is retracted from the lower position to the upper position due to the restoring force.

Gemäß einer weiteren Ausführungsform umfasst die Einstiegsvorrichtung eine Haltevorrichtung, womit die untere Trittstufe in der oberen Position fixiert werden kann. Auf diese Weise kann redundant sichergestellt werden, dass sich die untere Trittstufe immer in oberer Position befindet. Insbesondere könnte dies für den Betrieb des Schienenfahrzeugs notwendig sein, wenn das Rückstellelement defekt wäre und keine Rückstellkraft zum Halten der unteren Trittstufe in oberer Position bereitstellen könnte, zum Beispiel im Falle eines Bruchs einer Rückstellfeder.According to a further embodiment, the entry device comprises a holding device, with which the lower step can be fixed in the upper position. In this way it can be redundantly ensured that the lower step is always in the upper position. In particular, this could be necessary for the operation of the rail vehicle if the restoring element were defective and could not provide any restoring force for holding the lower step in the upper position, for example in the event of a restoring spring breaking.

Gemäß einer Weiterentwicklung ist die Einstiegsvorrichtung mit einem Sensorelement zum Detektieren einer Stellung der unteren Trittstufe versehen. Auf diese Weise kann verhindert werden, dass sich die untere Trittstufe in unerwünschter Weise in der unteren Position befindet. Insbesondere kann ein Warnsignal ausgegeben werden, wenn das Schienenfahrzeug in Bewegung gesetzt wird, jedoch die untere Trittstufe noch nicht eingefahren ist. Beispielsweise kann hierfür eine Endlagenschalter, insbesondere mit einer integrierten mechanischen Verriegelung, geeignet vorgesehen sein,According to a further development, the entry device is provided with a sensor element for detecting a position of the lower step. In this way, the lower step can be prevented from being in the lower position in an undesired manner. In particular, a warning signal can be output when the rail vehicle is set in motion but the lower step has not yet been retracted. For example, a limit switch, in particular with an integrated mechanical lock, can be provided for this purpose,

Gemäß einer weiteren Ausführungsform kann das Schienenfahrzeug mit einer Beleuchtungsvorrichtung im Bereich der Einstiegsvorrichtung ausgestattet sein, sodass ein Benutzen auch bei schlechten Sichtverhältnissen gefahrlos möglich ist. Insbesondere kann dabei die Beleuchtungsvorrichtung mit einem Endlagenschalter gekoppelt sein, so dass der Einstiegsbereich bei ausgefahrener Einstiegsvorrichtung stets beleuchtet ist.According to a further embodiment, 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. In particular, the lighting device can be coupled to a limit switch, so that the boarding area is always illuminated when the boarding device is extended.

Die voranstehenden beschriebenen Ausführungsformen können beliebig, jedoch in sinnhafter Weise miteinander kombiniert und erweitert werden, besondere es ist denkbar, dass der verschiebbare Teil der Einstiegsvorrichtung zwei untere Trittstufen umfasst, wobei möglicherweise mehrere obere Trittstufen vorgesehen sind. Auf diese Weise ließen sich größere Höhenunterschiede bewältigen.The above-described embodiments can be combined with one another and extended as desired, but in a sensible manner; it is particularly conceivable that the displaceable part of the entry device has two lower steps includes, possibly several upper steps are provided. In this way, larger differences in altitude could be managed.

Ausführungsbeispieleexemplary embodiments

Zur Verdeutlichung des Gesamtzusammenhangs wird in Fig. 1 ein Teil eines beispielhaften Schienenfahrzeugs 1 dargestellt, wobei es sich hierbei um einen Steuerwagen eines Wendezuges oder Triebzuges handelt. Unabhängig von der speziellen Ausführungsform hat ein solches Schienenfahrzeug 1 einen Fahrzeugkörper 4, welcher auf einem Räderwerk 3 auf Schienen 2 rollbar gelagert ist. Entsprechend befindet sich das Schienenfahrzeug 1 in einer Vertikalrichtung 7 über den Schienen 2. Die Vertikalrichtung 7 orientiert sich somit an der Betriebsposition des Schienenfahrzeugs 1.To clarify the overall context, 1 a part of an exemplary rail vehicle 1 is shown, this being a control car of a push-pull train or multiple unit. Regardless of the specific embodiment, such 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. Correspondingly, 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.

Im vorderen Bereich oder im Endbereich des Fahrzeugkörpers 4 des Schienenfahrzeugs 1 befindet sich eine Steuerkabine 26, worin zur Zugsteuerung notwendige Steuervorrichtungen für den Zugführer vorgesehen sind. Um direkt von außen in einen Innenraum 5 der Steuerkabine 26 zu gelangen, ist in der Außenwand des Fahrzeugkörpers 4 eine Türvorrichtung 9 vorgesehen.In the front area or in the end area of the vehicle body 4 of the rail vehicle 1 there is a control cabin 26, in which the control devices necessary for the train control are provided for the train driver. To direct from To enter an interior space 5 of the control cabin 26 from the outside, a door device 9 is provided in the outer wall of the vehicle body 4 .

Da ein Abstand zwischen einem Boden 27, zum Beispiel ein Schotterbett der Schienen 2, und der Türvorrichtung 9 je nach Ausführungsform in Vertikalrichtung 7 ganz erheblich ausfallen kann, ist das Schienenfahrzeug 1 mit einer Einstiegsvorrichtung 10 versehen, mittels derer der Abstand zwischen Boden 27 und einem Einstiegsbereich 6 der Türvorrichtung 9 von einer Person überwunden werden kann.Since the distance between a floor 27, for example a ballast bed of the rails 2, and the door device 9 can be quite considerable in the vertical direction 7, depending on the embodiment, the rail vehicle 1 is provided with an entry device 10, by means of which the distance between the floor 27 and a Entry area 6 of the door device 9 can be overcome by one person.

Die Einstiegsvorrichtung 10 ist dabei in unmittelbarer Nähe des Einstiegsbereichs 6 des Fahrzeugkörpers 4 des Schienenfahrzeugs 1 angeordnet. Im vorliegenden Fall befindet sich der Einstiegsbereich 6 unmittelbar an einer Türschwelle der Türvorrichtung 9. Rechts und links Querrichtung 8 neben der Türvorrichtung 9 können Handläufe 28 zum Unterstützen des Einsteigens vorgesehen sein.The boarding device 10 is arranged in the immediate vicinity of the boarding area 6 of the vehicle body 4 of the rail vehicle 1 . In the present case, 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.

Die eigentliche Einstiegsvorrichtung 10 wird den Fig. 2 bis Fig. 4 angeordnet am Einstiegsbereich 6 des Schienenfahrzeugs 1 detailliert wiedergegeben. Gemäß dieser nicht einschränkenden Ausführungsform setzt sich die Einstiegsvorrichtung 10 unter anderem aus zwei seitlichen, im Wesentlichen in Vertikalrichtung 7 verlaufenden Holmen 17 und 18, einer unteren Trittstufe 13, einer oberen Trittstufe 12 und einer darüber angeordneten, festen weiteren Trittstufe 22 zusammen.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. According to this non-limiting embodiment, 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.

Die Holme 17 und 18 werden dabei von einem Festteil 19 und einem dazu in Vertikalrichtung 7 am Festteil 19 verschiebbar angeordneten Ausziehteil 20 gebildet, und stellen eine Führungsvorrichtung 11 für die verschiebbare untere Trittstufe 13 dar. Die untere Trittstufe 13 steht dabei in fester Verbindung mit den Ausziehteilen 20, welche somit zusammen mit der unteren Trittstufe 13 gemeinsam eine U-förmige Gestalt aufweisen. Weiterhin ist an den Ausziehteilen 20 jeweils ein Hilfstritt 21 in Vertikalrichtung 7 über der unteren Trittstufe 13 vorgesehen. Die Holme 20, die untere Trittstufe 13 und die Hilfstritte 21 sind somit fest zueinander ausgebildet und formen eine starre Baueinheit.The rails 17 and 18 are formed by a fixed part 19 and an extending part 20 that is movably arranged on the fixed part 19 in the vertical direction 7 and represent a guide device 11 for the movable lower step 13. 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. Furthermore, 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.

Die Festteile 19 sind über die obere Trittstufe 12 und die weitere feste Trittstufe 22 fest miteinander verbunden und bilden eine weitere starre Baueinheit, welche am Einstiegsbereich 6 des Schienenfahrzeugs 1 befestigt ist.The fixed parts 19 are firmly connected to one another via the upper step 12 and the further fixed step 22 and form a further rigid structural unit which is fastened to the boarding area 6 of the rail vehicle 1 .

Die Ausziehteile 20 sind in Vertikalrichtung 7 verschiebbar in oder an den Festteilen 19 gelagert, wobei - gemäß dieser Ausführungsform - die Ausziehteile 20 zumindest teilweise von den Festteilen 19 aufgenommen werden können. Die Holme 17 und 18 werden somit durch die zueinander verschiebbaren Festteile 19 und Ausziehteile 20 gebildet und können als Führungsvorrichtung 11 verstanden werden.The pull-out parts 20 are slidably mounted in or on the fixed parts 19 in the vertical direction 7 , wherein—according to this embodiment—the pull-out parts 20 can be at least partially accommodated by the fixed parts 19 . The bars 17 and 18 are thus formed by the mutually displaceable fixed parts 19 and pull-out parts 20 and can be understood as a guide device 11 .

Anhand Fig. 2 wird die Einstiegsvorrichtung 10 in eingefahrener Stellung gezeigt, wobei sich die untere Trittstufe 13 in der oberen Position O befindet. Dabei ist die untere Trittstufe 13 in einer kastenförmigen Aufnahme 24 der oberen Trittstufe 12 vollständig aufgenommen. Weiterhin befinden sich die Holme 17 und 18 in einer eingezogenen Stellung, wobei die Ausziehteile 20 innerhalb der Körper der Festteil in 19 befindlich sind.Based 2 the entry device 10 is shown in the retracted position with the lower step 13 in the upper position O. The lower step 13 is completely accommodated in a box-shaped receptacle 24 of the upper step 12 . Furthermore, the beams 17 and 18 are in a retracted position with the extension parts 20 located within the bodies of the fixed part in 19 .

In Fig. 3 und Fig. 4 befindet sich die Trittstufe 13, und damit auch die Ausziehteile 20 und die Hilfstritte 21, ausgefahren in unterer Position U. Dabei ist erkennbar, dass die untere Trittstufe 13 derart an einem unteren Ende der Ausziehteile 20 und die Hilfstritte 21 so an einem oberen Ende der Ausziehteile 20 befestigt sind, dass die Hilfstritte 21 in der oberen Position O in Vertikalrichtung 7 im Wesentlichen dieselbe vertikale Position wie die weitere feste Trittstufe 22 einnehmen. Im Gegensatz dazu befinden sich die Hilfstritte 21 in unterer Position U der unteren Trittstufe 13 bezüglich der Vertikalrichtung 7 am Ort der oberen Trittvorrichtung 12.In 3 and 4 is the step 13, and thus also the extension parts 20 and the auxiliary steps 21, extended in the lower position U. It can be seen that the lower step 13 is positioned at a lower end of the extension parts 20 and the auxiliary steps 21 are positioned at an upper end of the Pull-out parts 20 are attached so that the auxiliary steps 21 in the upper position O in the vertical direction 7 are essentially the same vertical position as the further fixed step 22 . In contrast, the auxiliary steps 21 are in the lower position U of the lower step 13 with respect to the vertical direction 7 at the location of the upper step device 12.

Weiterhin sind in den Holmen 17 und 18 jeweils mindestens ein Rückstellelement 14 und ein Dämpfungselement 15 wirksam zwischen dem Festteil 19 und dem Ausziehteil 20 verbaut. Das Rückstellelement 14 stellt dabei eine Rückstellkraft R bereit, wodurch die Ausziehteile 20 zusammen mit der unteren Trittstufe 13 und den Hilfstritten 21 immer bestrebt sind, die obere Position O einzunehmen. Insbesondere können dabei die Rückstellelement 14 als Druck- oder Zugfederelemente ausgebildet sein. Gemäß dem Ausführungsbeispiel in Fig. 4 sind in den Holmen 17 und 18 weiterhin Dämpfungselement 15 koaxial zu den Rückstellelementen 14 vorgesehen. Mithilfe dieser geeignet ausgelegten Dämpfungselemente 15 kann eine der Rückstellkraft R entgegenwirkende Dämpfungskraft erzeugt werden, sodass ein Zurückschnellen der verschiebbaren Bauteile Ausziehteile 20, untere Trittstufe 13 und Hilfstritte 21 in Vertikalrichtung 7 effektiv verhindert wird.Furthermore, at least one restoring element 14 and one damping element 15 are installed in each of the bars 17 and 18 in an effective manner between the fixed part 19 and the pull-out part 20 . The restoring element 14 provides a restoring force R, as a result of which the pull-out parts 20 together with the lower step 13 and the auxiliary steps 21 always strive to assume the upper position O. In particular, the restoring element 14 can be designed as a compression or tension spring element. According to the embodiment in 4 damping element 15 are also provided in the bars 17 and 18 coaxially with the restoring elements 14 . These suitably designed damping elements 15 can be used to generate a damping force that counteracts the restoring force R, so that the sliding components, pull-out parts 20, lower step 13 and auxiliary steps 21, are effectively prevented from snapping back in the vertical direction 7.

Gemäß Fig. 2 befindet sich die Einstiegsvorrichtung 10 in der oberen Position O, sodass das Schienenfahrzeug 1 ein minimales Lichtprofil aufweist. Im Gegensatz dazu wird das Lichtprofil des Schienenfahrzeugs 1 vergrößert, wenn sich die Einstiegsvorrichtung 10 gemäß Fig. 3 und Fig. 4 in der unteren Position U befindet.According to 2 is the boarding device 10 in the upper position O, so that the rail vehicle 1 has a minimal light profile. In contrast, the light profile of the rail vehicle 1 is increased when the boarding device 10 according to 3 and 4 is in the lower position U.

Weiterhin kann zum Beispiel innerhalb der Holme 17 und 18 ein Sensorelement 25 derart vorgesehen sein, sodass sich damit die vorliegende Position O oder U der unteren Trittstufe 13 detektieren lässt. Insbesondere kann das Sensorelement 25 mit einer Steuerung des Schienenfahrzeugs 1 derart verbunden sein, dass ein Losfahren des Schienenfahrzeugs 1 bei einer sich in unterer Position U befindlichen unteren Trittstufe 13 unmöglich ist, oder eine entsprechende Warnung vorher ausgegeben wird.Furthermore, for example, a sensor element 25 can be provided within the bars 17 and 18 in such a way that the present position O or U of the lower step 13 can be detected. In particular, the sensor element 25 can be connected to a controller of the rail vehicle 1 in such a way that it is impossible for the rail vehicle 1 to move off when the lower step 13 is in the lower position U, or a corresponding warning is issued in advance.

Wenngleich hierin spezifische Ausführungsformen dargestellt und beschrieben worden sind, liegt es im Rahmen der vorliegenden Erfindung, die gezeigten Ausführungsformen geeignet zu modifizieren, ohne vom Schutzbereich der vorliegenden Erfindung wie sie in den angehängten Ansprüchen definiert ist, abzuweichen. Insbesondere kann die Einstiegsvorrichtung dazu mehrere untere Trittstufen und/oder mehrere obere Trittstufen aufweisen. Auch ist denkbar dass die Führungsvorrichtung der Einstiegsvorrichtung nur einen Holm aufweist, welcher die untere Trittstufe und/oder die obere Trittstufe T-förmig bzw. F-förmig trägt.While specific embodiments have been illustrated and described herein, it is within the scope of the present invention to appropriately modify the shown embodiments without departing from the scope of the present invention as defined in the appended claims. In particular, the entry device can have a number of lower steps and/or a number of upper steps for this purpose. It is also conceivable that the guide device of the entry device has only one bar, which carries the lower step and/or the upper step in a T-shape or F-shape.
