  • the extendable ladder is connected to the existing compressed air system of the vehicle.
  • An object of the present invention is therefore to provide an improved rail vehicle with a boarding device, wherein the boarding device has a simple and robust structure and is characterized in particular in use by high reliability and positive ergonomics.
  • the rail vehicle is formed inter alia by a vehicle body and a gear train, whereby the rail vehicle is mounted rollably on rails. Furthermore, the rail vehicle or the vehicle body of the rail vehicle has an access area and an entry device arranged thereon, which makes it possible to reach an interior of the vehicle body.
  • the entry area can be formed together with a door device. It is also conceivable, however, for the access area to be 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. In particular, this is an access exclusively for a driver and / or staff of the rail vehicle. That is, the boarding device is not suitable and / or intended to enable passengers who use the rail vehicle for passenger transport, in the ordinary use case, a boarding and alighting between a platform and the passenger compartment of the rail vehicle.
  • the boarding device is arranged in the immediate vicinity of the entry area and has a lower tread, a guide device, a return element and a damping element.
  • the entry area can be designed as a door sill and / or lower door edge of a door device.
  • the entry-level device is arranged in the vicinity of the door device in such a way that a person using the entry-level device can directly grasp and actuate the door device and ultimately move through the door device.

Abstract

La présente invention concerne un véhicule ferroviaire équipé d'un dispositif d'embarquement extensible. Il est évident que ces portes d'entrée sont agencées bien au-dessus du niveau du rail dans la carrosserie du véhicule. Afin de permettre au conducteur d'atteindre la porte d'entrée en l'absence de quai, de nombreux véhicules ferroviaires de ce type sont équipés d'une sorte d'échelle sur la paroi extérieure de la carrosserie du véhicule. Toutefois, les concepts de ces véhicules ferroviaires connus jusqu'à présent ainsi que les dispositifs d'embarquement correspondants sont très complexes et/ou sujets à des erreurs. La révélation concerne un véhicule ferroviaire qui est muni d'une zone d'embarquement et d'un dispositif d'embarquement. Le dispositif d'embarquement comprend une marche inférieure, un dispositif de guidage, un élément de rappel et un élément amortisseur. En particulier, la zone d'embarquement peut être conçue comme un seuil et/ou un bord inférieur d'un dispositif de porte. Le dispositif d'embarquement est positionné à proximité du dispositif de porte de telle sorte qu'une personne utilisant le dispositif d'embarquement puisse immédiatement saisir et actionner le dispositif de porte et se déplacer à travers le dispositif de porte.
