Description

Double-decker rail vehicle

The present invention relates to a double-decker rail vehicle, with a top floor extending in the direction of travel of the rail vehicle, with a

Lower floor extending in the direction of travel of the rail vehicle, the lower floor extending in a plane below the Oberstock, and with a staircase that connects the upper floor with the lower floor, the staircase is a spiral staircase with a plurality of m arranged a winding Trαttstufen.

Usually, in double-decker ski vehicles, the stairs connecting the upper floor and the lower floor are arranged at one or both ends of the passenger compartment, since the

Stairs at this point disturb the construction of the passenger compartment s least and can also be used here for connection to a mezzanine, which forms the entry area for the passengers or the passage to an adjacent wagon. Due to the end-side arrangement, the stairs are usually designed and aligned so that the entry and exit in the direction of travel, that is in Fahrzeuglangsπchtung done.

So far, the said stairs either as a two-door counter-rotating U-stairs with intermediate platform or as einlaufig half-spiraled stairs, usually m shape of a spiral staircase, so a spiral staircase with a spindle in the stairwell, executed. The conventional U-stairs with intermediate platform is indeed in the transverse direction, ie in the direction transverse to the entrance and exit, relatively narrow, but relatively long in the longitudinal direction. Will you therefore achieve a gain in space in the longitudinal direction, then the conventional spiral staircase is used in this case, which has just in the longitudinal direction just a total extent in the size of a step width zuzuglich half the spindle diameter. The spiral staircase, however, is significantly wider in the transverse direction than the conventional U-stairs, which is due to the design and the specifications for the step width, the number of stages and the Auftrittsmaß in the middle stage, which must be met in rail vehicles. The above specifications lead to the fact that in the spiral staircase in the transverse direction, the width of the stair eye or the spindle is many times greater than the width of the stair eye in the case of the U-stairs. Usually takes a spiral staircase therefore taking into account the current requirements for step width, step height and

Appearance in step center almost the entire vehicle width.

In railcars, also called head car, the double-deck type, is often additional space, especially in the

Head of the rail vehicle to provide for the drive units, which is why in this part of the rail vehicle is particularly little space for the arrangement of a staircase between the upper floor and lower floor at your disposal. This problem is solved in the prior art, for example, by the arrangement of a single-flight staircase that leads straight from the lower floor in the vehicle longitudinal direction in the upper floor. By Although the single-flight design of the stairs is won in the transverse direction space, but valuable space for the arrangement of seats is lost in the upper floor.

From Offenlegungsschπft DE 197 31 120 Al is a

Double-decker head carriage known in which at the head of a einhalb half-spiraled spiral staircase between the upper floor and lower floor is arranged with an exit to the front intermediate floor. To reduce the staircase dimensions, the diameter of the stairs is chosen to be relatively small, with the

Width of the steps and the Auftrittsmaß have also been reduced accordingly. In addition, the narrow appearance to the stair spindle hm relatively strong, which increases the risk of falling at a thoughtless step considerably. Therefore, the known staircase collides with the current operator demands for compliance with the TSI PRM (Technical Specificity for Interoperability). Thereafter, the entrance dimension in the middle of a tread should be at least 270 mm. If you want to realize this requirement with a spiral staircase, the diameter of the inner spindle must be chosen significantly larger than in the prior art, which leads to the fact that the spiral staircase in the transverse direction as mentioned above usually occupies almost the entire vehicle width.

The problem is in a spiral staircase with the inevitably larger diameter in addition to the reduced space for drive units also that m double-decker with limiting profile, for example, after UTC 505, a

Standard of the International Union of Railways (UTC, Union Internationale des Chemms de fer) such a spiral staircase can hardly be accommodated, since the 1 ichte height would be too low in the area of the exit step to the upper floor because of the retracted roof of the rail vehicle, that is, the outer edge of the stair ceiling weα t had to protrude over the sloping roof contour of the car. Spindle stairs of the type described above thus indeed require a small space in Fahrzeuglangsrichtung, the space requirement in the transverse direction leads when using the current set of rules, however, that spiral staircases in double-decker cars nowadays at least as a continuous stairway between

Lower floor and upper floor can be used in the manner described.

It is therefore an object of the present invention to develop a double-decker rail vehicle of the type mentioned in such a way that the connection between the upper floor and lower floor of the rail vehicle is designed to save space.

The previously derived and indicated object is achieved in a double-decker rail vehicle of the type mentioned in that several treads are designed and arranged according to the evolute method or circular cutting method.

The treads designed and arranged according to the Evo Lutenverfahren or circular cutting method allow for compliance with the TSI PRM rules, in particular the consideration of a Auftrittsmaßes of at least 270 mm, a significant gain in the longitudinal direction compared to the transverse m direction already relatively narrow conventional U-stairs, but also one Space gain in the transverse direction opposite the narrow longitudinal single-entry spiral staircase anyway. In other words, the spiral staircase provided in the double-decker rail vehicle according to the invention takes up less space than all previously known solutions and thus makes room for, for example, larger drive units and / or further seats.

In the evolute or circular cutting method s Lnd the individual treads designed so that the front

Step edge runs angularly to the rear step edge, as is the case in principle with a conventional spiral staircase. However, in contrast to the conventional spiral staircase, the steps do not start from a circular stairwell or a circular stair spindle, but from an elongate stairwell which, like the conventional spiral staircase, may also have a curved section in the form of a circular section, but in contrast to connect conventional extensions to each other parallel extensions, so that the stairwell and thus the stairs is substantially U-shaped. The leading edge and the trailing edge of the steps according to the evolute or circular cutting method are also at an angle to each other, which abuts the straight part of the stair eye, ie the two parallel legs of the U. The steps on the straight part of the stair eye are not, as in the conventional U-stairs provided with mutually parallel front and rear edges, but the treads have in this area already tapering towards the stair eye shape. The treads are thus in the inventive case already in the entry and / or exit arranged obliquely with respect to the transverse direction, so that the winding already begins in this area and not only in the region of the arcuate part of the stair eye, which is associated with a significant space savings.

In this case, preferably designed according to the Evolutenverfahren or Krej sschnittverfahren and arranged treads are arranged successively in the spiraling, which allows a simple construction of the stairs by the said method. In principle, it is also conceivable, different sections of the spiral staircase πu t treads by the Evolutenverfahren or circular cross-section and formed therebetween by other methods steps, for example, have a mirror-symmetrical shape as in a conventional spiral staircase to arrange. The greatest gain in space can be achieved in the case that at least the three or four treads closest to the apex of the helix, preferably the seven or eight treads closest to the bow apex, are part of the treads formed and arranged by the evolute or circular cutting method.

It is conceivable that in the apex of the turn] ung only a single step goes or border two treads according to another alternative. In the first case, the center line of the staircase, defined as a straight line passing through the apex of the arch and the center of the stairwell or the staircase spindle, can also form the center line of the tread arranged in the apex of the arch. In the case that two treads adjoin one another in the apex of the bow, the leading edge of the top of the two levels lying on the center line of the stairs. Both alternative arrangements lead to a largely symmetrical spiral staircase, which further simplifies the construction of the same.

According to a further embodiment of the erfmdungsgemaßen double-decker rail vehicle runs the center line of the stairs m the direction of travel of the rail vehicle. In this way, the stairs can be arranged end in the rail vehicle, the entry m the stairs and the exit from the stairs substantially m Fahrzeuglangsrichtung, ie parallel to the tabteil leading by the passenger gas gear, can be done.

According to yet another embodiment, the

Entry step and / or exit step Part of the educated and arranged by the Evolutenverfahren or circular cutting tread. If the entry level, ie the lowest of the steps, and / or the exit step, ie the uppermost of all steps, is also arranged and designed in the space-saving manner described above, overall the footprint of the staircase can be further reduced.

Since in certain types of double-decker rail vehicles, such as a double-decker with boundary profile to UIC 505, a retracted roof is provided in the upper floor and therefore the clear height of the vehicle center to the side wall decreases, it is advantageous if the upper part of the stairs so formed is and proceeds so that the exit step is arranged as far as possible to Fahrzeugmα te hm. In order to achieve such an arrangement, it is conceivable that the runlime, that is the connecting line between the center of the leading edge and the center of the trailing edge of the respective tread, at least the upper tread, in particular the upper two treads, preferably the top three treads, extending at an angle to the center line of the stairs. In this way, it is achieved that the running line approaches in the upper part of the stairs of the center line of the stairs and thus possibly also the center of the vehicle, so on the center line of the stairs or vehicle center tapers. In this case, the angle between the running lime of the respective tread and the center line of the stairs according to an embodiment between 10 and 30 °, which on the one hand the smallest possible dimensions of the spiral staircase can be achieved and yet an exit in the top floor is possible, as far as possible from the side wall and so that the retracted roof is removed.

With regard to the smallest possible Dαmensiomerung the spiral staircase at the same time the greatest possible comfort for the passenger, it is preferred according to yet another embodiment of the inventive double-decker rail vehicle, if the angle between the front step edge and the rear step edge of the treads formed by the Evolutenverfahren or circular cutting process and are arranged between 15 and 30 °, in particular between 18 and 25 °. In this way, a particularly high space gain can be achieved in the transverse direction and in the longitudinal direction, without thereby the treads get too small Auftrittsmaß in the middle of the stage.

The staircase described above is according to a particular embodiment of the double-decker rail vehicle a single-entry semi-spiral staircase, so that the passenger between the entry into the staircase and the outlet a turn of about 180 ° durchfuhrt.

As already mentioned, according to a further embodiment of the erf indungsgemungsgemaßen double-decker rail vehicle, the stair well, which may also be similar to a spindle provided with a vertical pillar, which runs in the middle of the staircase from the lower floor in the upper floor, U-shaped. This means that the stairwell, from which the treads radiate outwards, has two parallel sides which are interconnected to the apex of the helix. The connection between the two parallel sides can be realized in any conceivable form, in particular arcuate.

Finally, the rail vehicle according to yet another embodiment is a railcar, the stairs being arranged in particular in the head end of the rail vehicle. In a railcar is due to the drive units to be housed, especially at the head of the rail vehicle, little room for a staircase between the upper floor and lower floor, which is why the spiral staircase described above is particularly useful here.

There are now a variety of ways to design and develop the inventive double-decker rail vehicle. For this purpose, on the one hand, reference is made to the claims subordinate to claim 1, on the other hand to the description of exemplary embodiments in conjunction with the drawing. In the drawing shows: Fig. 1 is a first Ausfuhrungsbei spie 1 a

Spiral staircase for a double-decker rail vehicle according to the present invention, and

Fig. 2a) to c) different views of a part emes

Double floor rail vehicle with a second exemplary embodiment of such a spiral staircase.

Fig. 1 shows a plan view of an exemplary embodiment of a spiral staircase 4 for a Doppe] stock rail vehicle 1, as will be described in more detail with reference to the figures 2a) to c).

The spiral staircase 4 has a plurality of m einet: Wende] arranged treads 5a, 5b, ..., 5i, of which several, namely the treads 5a, 5b, ..., 5h formed and arranged by the Evolutenverfahren.

After the evolute method, the treads 5a, 5b, 5g and 5h, which adjoin the two parallel sides of the stair eye 9, formed trapezoidal and arranged so that the treads tapered to the stair eye 9 hm. The steps 5c, 5d, 5e and 5f, which run towards the middle of the staircase hm on a kreisbogenformigen portion of the stair eye 9, which connects the two parallel sections of the stair eye 9 are formed and arranged by the Evolutenverfahren. The steps 5c, 5d, 5e and 5f are trapezoidal and taper towards the stair eye 9 hm. In contrast to a conventional spiral staircase 4, the stair eye 9 is elongate, here U-shaped, formed, wherein the base of the U is formed by a semicircle. Equally, however, it would also be conceivable to design the base of the U, which connects the parallel sides of the stair eye 9, to which the steps 5a, 5b, 5g, 5h run, in another form, for example, as in FIG. 2b) and c ) instead of a circular arc with a straight line that runs perpendicular to the two parallel sides of the stair eye 9.

In the case shown in Fig. 1, the treads with the exception of the exit stage 5i, ie the uppermost stage, formed and arranged by the Evolutenverfahren. Alternatively, for a space-saving training as possible

Spiral staircase 4 also conceivable to form a plurality of steps according to the circular cross-section method, in which the treads, which adjoin the straight edge of the stair eye, were also formed trapezoidal. These steps are also offset obliquely by two methods compared to a conventional U-stairs, so rotated by a certain degree relative to the transverse direction of the stairs. In other words, in steps of this kind, the step center line, that is, an imaginary straight line, passes through the respective centers of the right and left

Step side runs, at an angle to the transverse direction of the staircase. In treads according to the evolute method, the step is set in relation to the circular cutting process stronger in relation to the staircase transverse direction, ie angled. Also, the treads tapered according to the Evolutenverfahren to the stair well 9 towards stronger than treads after the circular cross-section process. In the embodiment shown in FIG. 1, the eight treads 5a, 5b,..., 5h closest to the apex 6 of the helix are formed and arranged according to the evolutive method, whereas the exit step 5i is formed and arranged separately, namely such that the passenger is directed in the direction of the center of the stairs and thus in the direction of the center of the passenger compartment, as otherwise the clear height in the area of the exit step would not be sufficiently large in the upper floor with a retracted roof.

The trained and arranged by the Evolutenverfahren treads 5a, 5b, ..., 5h have as said a trapezoidal shape, wherein the steps taper towards the stair well 9. Here is the angle between the respective

Step leading edge 7a, 7b, ..., 7h and the respective step trailing edge 8a, 8b, ..., 8h in a range between 19 ° and 24 °.

Another special feature in the illustrated

Embodiment is the course of the line L, which is arranged at the entrance step 5a parallel to the center line M, defined as a straight line passing through the apex of the bow 6 and the center of the stair eye 9. In the treads 5d and 5e, which adjoin one another in the apex of the helix, the line L runs almost perpendicular to the center line M. In the exit step 5i, the line L runs at an angle of about 30 ° to the center line M, whereby the staircase in Direction center line M and thus preferably in the direction of the vehicle center is performed. As an alternative to the arrangement shown, in which the treads 5d and 5e adjoin one another in the apex of the vertex 6, it is also conceivable to arrange only a single tread in the vertex 6, from which the respective steps running up and down were constructed.

An installation example for a spiral staircase 4, as described above by way of example with reference to FIG. 1, is shown in FIGS. 2a) to c). The staircase 4 shown here corresponds essentially to the previously described staircase 4, but the outer boundary of the staircase 4 and da e inner boundary of the staircase 4, so the stairwell, not in a curved line, but is formed by individual straight sections. It should be emphasized that also in the case shown in Figures 2b) and c) the stair eye 9 U-forrru g is formed, in which case, however, the base of the U is a straight line perpendicular to the two parallel m vehicle direction extending sections the stair eye goes.

The staircase 4 is located at the head end 10 of a double-decker rail vehicle 1 and connects an upper floor 2 with a lower floor 3, which runs in a plane below the upper floor 2, the upper floor 2 and the lower floor 3 m travel direction of the rail vehicle 1.

Fig. 2c) shows the lower Tei] the staircase 4, the treads ebenfa] Is formed and arranged according to the Evolutenverfahren. In this case, the leading edge of the entrance step is arranged perpendicular to the center line of the staircase 4. As can be seen from FIG. 2b), the upper part is arranged the staircase so that the exit step to the vehicle center points out where the largest clear height of the upper floor 2 is present.

The third step from below is, as shown in Fig. 2c), at the height of the front intermediate floor 11, which includes the Fuhrerstand arranged, and can from the staircase 4 through a door 1? to be entered.
