Description

The invention relates to a large-capacity vehicle for passenger transport with a bridging plate for bridging a gap between an entry area of the large-capacity vehicle and a platform, the bridging plate being mounted on a car body of the large-capacity vehicle such that it can rotate about a first axis in the entry area.

The entrance to a rail vehicle should be as level as possible for passengers, especially for people with reduced mobility (PRM). A prerequisite for level access to a rail vehicle is that the height of the platform matches the height of the floor of the rail vehicle within the tolerances that occur. In order to make it easier for people in wheelchairs or passengers with prams to board, the gap between the edge of the rail vehicle's entrance and the edge of the platform must be as small as possible. In metros, the platform is usually on the straight track and is brought as close as possible to the track. The vehicle, in turn, is designed to allow only a small amount of lateral play. On high-speed trains, the lateral play cannot be set so small that the platform can be positioned close enough to the track, so that tools must be used to bridge the gap. For this purpose, vehicle-side sliding steps are generally used, which move out of the rail vehicle horizontally below the floor and reduce the gap to a platform at the same height as the vehicle floor.

For example, the WO 2015/150094 A1 such a sliding step which, in addition to compensating for different platform heights, has a pivotable part of the tread surface of the sliding step. Also the WO 2015/165677 A1 discloses a sliding step and a foldable step plate for bridging a vertical gap between the floor and the sliding step, which closes an opening in the outer skin for the sliding step when folded.

In existing vehicles, however, the integration of a sliding step can be very complex and therefore expensive or even technically impossible. For this purpose, manually inserted and locked ramps have become known, such as from EP 2 489 568 A2 or from the German patent application with the application file number not yet published at the time of this invention 10 2020 205 509.2 . Vehicle personnel remove such loose ramps from an accommodation location in the vehicle and place them over the gap, which in turn is very time-consuming and personnel-intensive. This makes it difficult for passengers to change quickly.

For a quick change of passengers, it is therefore useful if a footboard to bridge the gap is mounted directly in the entrance and can be moved by a suitable mechanism. the WO 2014/106581 A1 now teaches a fold-out running board which, when folded, closes a recess in the door leaf of an entrance door. However, retrofitting existing vehicles is also very expensive here, since the door is also affected along with the folding step and would have to be adjusted or replaced accordingly.

The invention is based on the object of specifying a device for bridging gaps for large-capacity vehicles which is technically easy to implement and economical to operate.

The object is achieved by the subject matter of independent patent claim 1. Further developments and refinements of the invention are reflected in the features of the dependent patent claims.

A folding step arrangement according to the invention for a spacious vehicle, in particular for a rail vehicle, comprises at least one bridge plate that can be mounted to rotate about a first axis, at least one handrail that can be mounted to rotate about a second axis, and at least one pendulum support that can be rotated about a third axis on the bridge plate and about a fourth Axis is rotatably mounted on the handrail and has a predetermined length between the third and fourth axis. The folding step arrangement is suitable for installation in an entry area of a car body of a large-capacity vehicle and is designed to be arranged in the large-capacity vehicle, in particular in a rail vehicle, in such a way that the bridge plate in an entry area of the vehicle can be rotated about the first axis on the car body of the large-capacity vehicle Vehicle is mounted, and that the handrail is rotatably mounted in the entry area about the second axis on the car body of the spacious vehicle.

The bridging plate serves as a fold-out step device for passengers to enter or exit the large-capacity vehicle and to bridge a gap between the boarding area of the vehicle and a stationary platform, such as a platform. It is suitably designed for people to enter.

A large-capacity vehicle according to the invention for passenger transport, in particular a rail vehicle, in particular a rail vehicle, in particular for public transport, comprises at least one folding step arrangement according to the invention, which is fastened to a car body of the large-capacity vehicle in an entry area of the large-capacity vehicle such that the bridge plate is in the entry area is rotatably mounted on the car body of the large-capacity vehicle about the first axis, and that the handrail is mounted rotatable about the second axis on the car body in the entrance area of the large-capacity vehicle, the second axis running at a predetermined distance in the vertical direction above the first axis.

The bridge plate and the handrail are each arranged on the car body of the large-capacity vehicle, for example on a shell structure of the car body of the large-capacity vehicle, and are connected to it in such a way that they can be rotated about the corresponding axes and thus folded in and out. The bridge plate could therefore also be referred to as a foldable step plate or as a folding step.

The second axis can advantageously run parallel to the first axis. The folding step arrangement is designed accordingly and is arranged on or in the vehicle. The folding step arrangement can also be designed and installed in the specified installation position on the vehicle in such a way that the third and fourth axes run parallel to one another and parallel to the first and/or second axis.

According to a development, the first axis can be arranged in the region of a first end face of the bridge plate, in particular directly on the first end face of the bridge plate. For this purpose, the bridge plate can have a receptacle, for example a bore complementary to the first axle, for the first axle or a pin-shaped axle stub for storage in a complementary receptacle in the car body of the large-capacity vehicle. It is also possible for bearing shells, for example of a plain or roller bearing, to be arranged between the receptacle and the axle. Recording and axis are then designed accordingly.

Similarly, the handrail can also have a receptacle, for example a bore complementary to the second axle, for the second axle or a pin-shaped stub axle for storage in a complementary receptacle in the car body of the large-capacity vehicle. The axis can advantageously in turn be arranged in the area of one end, in particular directly at one end of the handrail.

Equally, the third and the fourth axis can be arranged on a respective second end face of the bridge plate opposite the first end face of the bridge plate or second end of the handrail opposite the first end of the handrail.

The first and the fourth axis run in particular on both sides of the bridge plate.

The handrail and pendulum support are also advantageously provided in duplicate, with the pendulum supports then being arranged on both sides of the bridge plate and mounted on the bridge plate. Accordingly, the handrails can also be arranged on both sides and frame, for example, a projection of the bridge plate perpendicularly onto the bridge plate. An arrangement on only one side of the bridge plate is also conceivable.

The length of the pendulum support between the third and the fourth axis advantageously corresponds to a normal height between a handrail and a tread, in particular between 800 mm and 1200 mm. According to one embodiment, the third and the fourth axis are each arranged in the region of the opposite ends of the pendulum support.

A large-capacity vehicle according to the invention for passenger transport, in particular a rail vehicle, thus comprises at least one bridge plate for bridging a gap between an entry area of the large-capacity vehicle and a platform, in particular a stationary platform, for example a platform, the bridge plate being rotatable about a first axis in the entry area is mounted on a car body of the large-capacity vehicle, the large-capacity vehicle comprising at least one handrail which is mounted on the car body of the large-capacity vehicle in the boarding area so that it can rotate about a second axis, the second axis being at a predetermined distance in the vertical direction above the first axis and in particular parallel to the first axis, and that the large-capacity vehicle comprises at least one pendulum support which is pivoted about a third axis on the bridge plate and pivots about a fourth axis on the handrail and which is between the third and fourth A axis has a predetermined length.

According to a further development of the invention, the first and second axles are arranged in the entry area of the spacious vehicle in such a way that the first and second axles are in an imaginary vertical plane, in particular parallel to a central longitudinal plane through the spacious vehicle or through a car body of the spacious vehicle. the parallels Axles span an imaginary plane which, in particular, runs parallel to a likewise imaginary vertical plane through the center of the large-capacity vehicle.

In a further development, the bridge plate and the handrail are designed in such a way that a distance between the first and the third axis is the same as a distance between the second and the fourth axis.

According to a further development, the specified length of the pendulum support between the third and fourth axis is the same as the specified distance between the first and second axis, so that the axes form the corners of an imaginary parallelogram. An idealized, imaginary parallelogram is created from the handrail, pendulum support and bridge plate, as well as an imaginary line between the first and second axis, in such a way that the handrail is always guided parallel to the bridge plate. The corners of the imaginary parallelogram, which in particular runs transversely to the vehicle's central longitudinal axis, are formed by the first, second, third and fourth axis in every position of the bridge plate, handrail and pendulum support.

A further development provides that the first, the second, the third and the fourth axis are arranged in the entry area of the spacious vehicle in such a way that the first, the second, the third and the fourth axis run parallel to one another. All of the axes can be arranged not only parallel to one another, but in particular also parallel to a longitudinal central axis of the car body of the large-capacity vehicle.

According to a further development, the first axis is arranged in the area of an outward-facing end face of a floor of the spacious vehicle in the entry area, so that the bridge plate extends the floor to bridge the gap between the entry area and the platform. According to one embodiment, the bridging plate is arranged abutting on the outward-facing end face of the floor of the large-capacity vehicle in the entry area. According to one embodiment such that the bridge plate extends the floor to bridge the gap, in particular without a gap and in a predetermined, folded-out position, in particular flush. In principle, a small step between the floor and bridge plate is also possible within the framework of the specifications according to TSI, but a flush and essentially gap-free abutment of the bridge plate in its unfolded position on the floor, so that it extends the floor through the door opening, is preferred.

The first end face of the bridge plate can be arranged in the predetermined installation position in the area of a floor in the interior of the vehicle in its entry area. Accordingly, the first axle is further developed inside the vehicle behind a door opening in the car body of the large-capacity vehicle.

The first axis is thus offset inside the car body of the spacious vehicle in the entry area behind a door opening in the car body and thus also completely behind an entry door which closes the door opening in the entry area in the closed position. The entrance door is a further development of a pivoting sliding door.

If the bridge plate is folded in or folded up, it is located completely within the car body and thus inside the vehicle behind the door. Folded out or down, the bridge plate forms the folding step and bridges the gap between the floor in the boarding area and the platform. The bridge plate protrudes through the door opening when the entrance door is open.

The door opening runs in particular parallel to a longitudinal center plane of the spacious vehicle. If the second axis is in a vertical plane parallel to a longitudinal center plane of the spacious vehicle, the second axis is also behind the door opening. A longitudinal median plane runs vertically parallel to the longitudinal median axis of the car body and cuts the vehicle in two halves in longitudinal section.

According to a further development of the invention, the bridge plate is designed such that, in a folded position, it has an angle of less than 120°, in particular between 80° and 100°, to the floor of the spacious vehicle in the entry area. The angle is always greater than 0°. It is measured from the tread surface of the floor to the tread surface of the bridge plate. At 0°, the bridge plate would run parallel to the floor of the spacious vehicle in the entry area, with the respective treads facing each other. With a 360° that is practically impossible, the bridge plate and the floor again run parallel to each other, with the respective treads pointing in opposite directions. If the bridge plate runs flush with the floor of the spacious vehicle in the entry area in a folded-out position, the angle between the tread surface of the floor and the tread surface of the bridge plate is 180°.

An angle in the unfolded position of the bridge plate to the floor of the large-capacity vehicle in the entrance area is according to TSI between 180+10.2° and 180-10.2°. The inclination of the bridge plate is thus between +18% and -18% with respect to a horizontal plane.

Movement of the handrail is coupled to movement of the bridge plate. It runs in particular parallel to the bridge plate in every position of the bridge plate.

The entry door of the spacious vehicle is a further development of a pivoting sliding door.

According to a further developed solution, the large-capacity vehicle is designed in the entry area in such a way that it has a free space below the door opening, so that the bridge plate can be moved into an evacuation position at an angle greater than 220°, in particular between 240° and 280°, to the floor of the large-capacity vehicle in the Entry area can be folded down around the first axis. The floor in the entrance area and the body shell of the vehicle have a vertical distance to each other in the area of the door opening. Thus, a first axis adjacent to the end face of the floor in the boarding area also has this distance to the bodyshell structures of the large-capacity vehicle, which means that there is free space in the vertical direction below an imaginary extension of the floor or below the unfolded bridge plate, in which the bridge plate can be moved into the evacuation position is foldable. In the event of an evacuation, it can be almost completely hung down. The first axis can advantageously be arranged directly adjacent to the door opening, so that the folded-in bridge plate does not touch the closed entrance door, but runs closely along it, forming a small gap. In the folded position, however, the bridge plate is arranged completely behind the closed entrance door.

A ladder can then be positioned manually at the entrance for evacuation. The handrail and the pendulum support can then also be used for hand guidance in the evacuation position.

The bridge plate could also have at least one step that can be pulled out of the bridge plate, which could serve as an evacuation step and make an external ladder superfluous.

The bridge plate is further developed from a folded-in position into a folded-out position and vice versa from the folded-out position into the folded-in position by moving the handrail. The movement of the handrail is imposed on the bridge plate by the mutual coupling. The handrail itself can be operated manually. The movement as a whole is thus accomplished by the passenger or by the train crew, in particular by applying a force to the handrail, for example by hand. The folding step arrangement is designed accordingly for manually unfolding the bridge plate by moving the handrail from a folded position into an unfolded position. Additionally or alternatively, the movement is supported by a motor or is effected completely by a motor. An electric motor can be provided for this purpose.

A folding step arrangement according to the invention can be retrofitted to existing vehicles or integrated into existing structures with little effort. Only a small amount of installation space is required and no significant adjustments to the shell construction are required. A sliding step, for example, requires an installation space of approx. 120 mm to 140 mm in height within the floor structure and the shell. The bridge plate itself remains at the floor height of approx. 20 mm.

The invention permits numerous embodiments. It is explained in more detail with reference to the following figures, each of which shows an exemplary embodiment. Identical elements in the figures are provided with the same reference symbols.

• 2 shows the folding step arrangement 1 in a partially folded position,
• 3 shows the folding step arrangement 1 in a fully folded position,

In 1 is a car body of a large-capacity vehicle according to the invention, here a car body of a rail vehicle, shown schematically in cross-section through an entry area 2 of the large-capacity vehicle. It includes a folding step arrangement with a bridge plate 1, a handrail 7 and a pendulum support 9.

The bridge plate 1 is used in the illustrated unfolded position with the door open to bridge a gap 12 between the entry area 2 of the spacious vehicle and a platform 5. It is rotatably mounted on the car body about a first axis 6. The first axis 6 is located on an end face of the bridge facing the boarding area 2 ckenblechs 1 and in the area of a door opening 3 facing front side of a floor 4 in the entry area. In the form outlined here, the bridge plate 1 abuts the floor 4 in the unfolded position in order to extend this essentially without a gap, in particular up to the platform 5 . Floor 4 and bridge plate 1 are aligned in a common plane. In this position, the bridge plate 1 has an angle to the floor 4 of the spacious vehicle in the entry area, which is within the scope of the specifications of the TSI.

The handrail 7 is also rotatably mounted on the car body about a second axis 8 . The first and the second axis 8 are parallel and lie in an imaginary, vertical plane.

At one end of the handrail 7 opposite the second axis 8 , the pendulum support 9 is mounted on the handrail 7 such that it can rotate about a fourth axis 11 . Likewise, the pendulum support 9 is rotatably mounted on the bridge plate 1 about a third axis 10 . A distance between the first axis 6 and the third axis 10 is the same as a distance between the second axis 8 and the fourth axis 11. The length of the pendulum support 9 between the third axis 10 and the fourth axis 11 is also the same as the distance between the first axis 6 and the second axis 8, so that the axes form the corners of a parallelogram such that the handrail 9 is always guided parallel to the bridge plate 1. All axes 6, 8, 10 and 11 run parallel to each other.

Handrail 7 and pendulum support 9 are part of a mechanism for folding the bridge plate 1 in and out. The handrail 7 therefore also serves as an operating lever for manually moving the bridge plate 1. To simplify the operating process, the mechanism can be motor-driven, so that central operation or local operation can also be carried out by passengers, for example. A suitable decoupling of the drive from the mechanism is provided for emergencies in order to enable actuation even without a power supply.

Here the bridge plate 1 has a short overhang between the third axis 10 and a front face of the bridge plate 1 facing away from the vehicle. This is comparatively short here, so that the third axle 10 is considered to be attached in the area of the face of the bridge plate 1 facing away from the vehicle. Equally, the handrail 7 could also have an overhang, in particular of the same length, between its front end facing away from the second axis 8 and the fourth axis 11 . The length of the handrail 7 would then be slightly greater than the distance between the second and fourth axis 8 and 11.

In 2 the folding step arrangement is shown in a partially folded or unfolded position. The articulated components described above can again be seen and how they form a parallelogram, so that the handrail 7 is guided parallel to the bridge plate 1 .

3 now shows the folding step arrangement brought into a folded position. Here the mechanism for actuating the bridge plate 1 with the handrail 7 and the pendulum support 9 is arranged in a stowed position inside the vehicle in front of the closed door. The folded position could also be referred to as the basic position. The bridge plate 1 stands vertically in front of the door, and the pendulum support 9 and the handrail 7 are also in a vertical position, with the handrail 7 being oriented upwards from its second joint 8 on the vehicle side. If the mechanism is actuated from the basic position, after opening the door the handrail 7 is moved from the vertical position to the in 1 shown horizontal position moves. The pendulum support 9 moves the coupled bridge plate 1 parallel to the handrail 7 . The end point of this movement is reached when the bridge plate 1 comes to rest on the platform 5.

If there is no platform 5 or a very low platform 5, the bridge plate 1 can be pivoted further down beyond the unfolded horizontal position until it hangs almost vertically on the vehicle, as described below in FIGS 4 and 5 is illustrated. In the event of an emergency, it is thus possible to carry out a necessary evacuation using ladders without the bridge plate getting in the way.

5 shows the folding step arrangement in the evacuation position and 4 shows - analogous to 2 - A folding step arrangement that has not yet been fully deployed in the evacuation position.

As in the unfolded position to bridge the gap 1 the bridge plate 1 also protrudes through the door opening 3 in the evacuation position when the entrance door is open, but in contrast to this does not rest on a stationary platform. It therefore does not form an extension of the floor 4 of the spacious vehicle. Rather, it is folded down until it rests against a stop on the car body. In the illustrated evacuation position, the bridge plate 1 has an angle of almost 270° to the floor of the spacious vehicle in the entry area. The angles are measured from the stepping surface of the floor 4 to the stepping surface surface of the bridge plate 1. In order to realize this, a free space below the door opening 3 is provided. The vehicle contour is slightly curved, so that the outer skin of the vehicle below the door opening 3 is slightly inclined to a central longitudinal axis of the vehicle. The floor 4 extends almost to the first axis 6, but not the shell underneath.
