Escape ramp for a passenger rail vehicle

Technical area

The invention relates to an escape ramp for a

Passenger rail vehicle.

State of the art

The passengers of rail vehicles usually leave the rail vehicle in emergencies via the entrances provided for normal operation. This is a feasible Evakuierungsweg at full railways, but often fails in local trains, especially in subways. is

There is no space at the side of the rail vehicle, for example in tunnels, so that the only evacuation route is a frontal exit from the rail vehicle. Here is the considerable difference in level between the

Passenger compartment floor and the track bed to note. This level difference can be overcome only by means of a ramp-like construction or a staircase or ladder, otherwise there is a very high risk of injury to the passengers. In particular, this emergency exit must also by frail persons, with limited

Lighting situation in a tunnel can be used quickly and safely. According to the prior art, ramp-like devices are unfolded on the front side by means of which the passengers can leave the rail vehicle. For example, DE 4433371 or DE 4108575 disclose such ramps. When evacuating passengers are two ways to distinguish. On the one hand, the passengers can be evacuated to the track (at track level) or the passengers can move on to another

The known ramps are not suitable for this purpose Furthermore, a particular disadvantage of the known ramps that they have a considerable space requirement and thereby the design of the front ends of a

Rail vehicle complicate.

DESCRIPTION OF THE INVENTION The invention is therefore based on the object, a

Escape ramp for a passenger rail vehicle indicate that both the evacuation of passengers on the

Track level as well as at the same level permits and only a small space requirement when retracted

having.

The task is done by an escape ramp for a

Passenger rail vehicle with the features of claim 1 solved. Advantageous embodiments are the subject

subordinate claims.

According to the basic idea of the invention, an escape ramp for a passenger rail vehicle, which is arranged in a rest position below the emergency exit of the passenger rail vehicle and enables the evacuation of persons from the passenger rail vehicle in a position of use, wherein the escape ramp comprises a frame of at least two

Subframe has and these subframes pushed together are arranged, and a tread is provided which forms a walk-in area in the position of use of the escape ramp.

In this case, the escape ramp is at rest in a space-saving position below the front end entry of the rail vehicle over which the people are to be evacuated. The escape ramp comprises a frame consisting of at least two (but generally several)

Subframe consists, which are slidably mounted in each other in the manner of the telescope.

In such a way, an escape ramp with the required length can be stowed together in a small footprint. The required length of the escape ramp is calculated from the height of the passenger compartment above the rail bed level and the

desired inclination angle of the escape ramp determined in the use position. At rest, the escape ramp is below the

Emergency exit arranged, typically in the subframe of the car body. With objective invention, the advantage can be achieved to equip a rail vehicle with an emergency exit door, which allows both the evacuation of the passengers on the track bed level and the evacuation in another rail vehicle.

These two evacuation types are made possible by different operation of the same emergency exit door.

The accessible area of the escape ramp, the tread surface, is made of flexible material (eg plastic fabric). As a result, the advantage can be achieved to be able to stow the tread as possible to save space in the rail vehicle. An embodiment of the invention provides to stow the tread rolled in rest position.

A further embodiment of the invention provides for stowing the tread folded in the rest position.

It is advantageous to provide the tread with reinforcements, which are provided normal to the extension direction of the escape ramp and which preferably fixed to the

Tread are connected. For example, the plastic fabric used as tread can have reinforcements made of aluminum profiles. Likewise, reinforcements made of correspondingly strong plastics can be used.

The tread is guided on its longitudinal sides on the frame of the escape ramp and attached to these sides sliding on the frame. Furthermore, the tread is on her

End face (the extension side edge) firmly connected to the frame of the escape ramp. In such a way, the tread is automatically driven along with an extension of the frame. It is beneficial to use the escape ramp with two

To provide use positions. A first use position is used to evacuate people to the level of the rail bed, the frame of the escape ramp is fully extended (to its maximum extension length) and then the side facing away from the rail vehicle is lowered onto the rail bed.

A second position of use serves the evacuation of

Persons into a substantially level-identical further rail vehicle ("train to train" evacuation) .The frame is only extended to the respectively required length which is required to bridge the intermediate space to the further rail vehicle leave this second position of use in a horizontal position.

The escape ramp is with a rail vehicle side

arranged joint, which allows both the lowering (angling) of the ramp for the first use position and the maintenance of the substantially horizontal position of the frame in the second position of use. Furthermore, it is advantageous to the escape ramp with a

To provide Ausfahrbegrenzung, which interrupts the extension movement when the outgoing ramp meets an obstacle (for example, another rail vehicle). For this purpose, corresponding sensors are at the front edge of the frame

Provide (limit switch).

The drive of the escape ramp is preferably carried out by means of a pneumatic drive. This is particularly beneficial because of pneumatic energy in many rail vehicles

is provided. Due to the extension length of the escape ramp, which is typically a few meters, the actuation by means of a single actuator (pneumatic cylinder) is not advantageous. It is significantly more advantageous to provide an actuator between adjacent subframes, since in this way the conventional actuators can be used without the need for special and very expensive special actuators.

It is likewise advantageous to connect a plurality of actuators directly to one another (series connection) and thereby to achieve the required extension length, wherein each individual actuator is a standard component. Furthermore, it is advantageous to provide an emergency operation, which allows a manual extension even in case of failure of the main drive energy for the escape ramp.

Embodiment of the invention

Fig.l shows an example and schematically a

Passenger rail vehicle with an escape ramp in rest position. It is a longitudinal section through a passenger rail vehicle 2 shown in a frontal part, which with a

Escape ramp 1 is equipped. The passenger rail vehicle 2 has an emergency exit door, which is arranged on the front side, for example in the vehicle driver's cab. Below this emergency exit door the escape ramp 1 is arranged.

2 shows an example and schematically a

Passenger rail vehicle with an escape ramp in

Operating position. It is the passenger rail vehicle 2 with an escape ramp 1 in a first position of use

shown. In this first position of use, the escape ramp 1 extends substantially from the level of

Passenger compartment floor up to the level of the rail bed. In a second position of use (not shown in FIG. 2) the escape ramp 1 is arranged in a substantially horizontal position and can be extended by a shorter distance, so that the gap is bridged to another rail vehicle and the passengers in this further

Rail vehicle can be evacuated. The escape ramp 1 can, starting from the rest position in each of the two

Operating positions are moved, the type of operation determines the respective position of use.

3 shows an example and schematically a rolled

Tread. A tread 3 is in a rolled

Position shown in which the tread surface 3 is arranged in rest position. Reinforcements 4 are in certain,

preferably uniform intervals provided on the tread surface 3, whereby the tread surface 3 receives a much higher rigidity in the transverse direction and is thus suitable for the load by the weight of the evacuating passengers. As a result, a light, flexible and rollable material can be used as a tread surface 3.

4 shows an example and schematically a folded

Tread. In addition to the rolled shown in Fig.3 Storage, the tread surface 3 may be stored in segmented folded nature in rest position. In this case, stiffer material for the tread surface 3 can be used. The reinforcements 4 can be used as joints (hinges)

be executed to a particularly tight, space-saving

To allow folding of the tread 3.

Figure 5 shows an example and schematically escape ramp supervision - extended. It is shown a plan view of an escape ramp 1 in a position of use. The escape ramp 1 comprises a frame 5 which consists of a plurality of sub-frame 6, which are interconnected with the respective adjacent sub-frame 6 slidably. This arrangement on the type of telescope allows a space-saving storage of the escape ramp 1 at the same time the greatest possible range. The sliding connection of the sub-frame 6 takes place

preferably via known Teleskopschiebebeschläge.

6 shows an example and schematically an escape ramp in a top view - rest position. It is a frame 5 one

Escape ramp 1 shown in pushed together rest position. A tread surface 3 (not shown in Figure 6) in attached to the end of the extending end of the frame 5, so that upon extension of the escape ramp 1, the tread surface. 3

is automatically pulled out with.

7 shows an example and schematically a pneumatic drive - series connection. It is a drive for one

Escape ramp 1 shown, which a plurality

having pneumatic actuators 7, which are connected to each other in series. This is a big one Extendable reachable without a single pneumatic drive 7 must be able to operate the entire extension.

8 shows an example and schematically a pneumatic drive - single drive. It is a drive for one

Escape ramp 1 shown, each individual sub-frame 6 has its own pneumatic drive 7 and is such a way individually operable. As a result, for example, in a second position of use (evacuation train to train) explicitly the vehicle-side, wider sub-frame can be extended and the narrower sub-frame 6 remain for use in a first position of use (evacuation train - rail level).
