Description

Technical area

[0001] The present invention relates to a passenger transport vehicle, in particular a rail vehicle or a bus. Such passenger transport vehicles are known from local and long-distance transport and serve various train stations and stops. Typically, such stops or train stations are equipped with platforms from which passengers can board and disembark the passenger transport vehicle directly from an elevated position through door devices. Previously known state of the art

[0002] Also common are passenger transport vehicles with two decks, allowing passengers to be transported on two levels. For this purpose, the passenger transport vehicles usually feature steps that allow passengers to access the lower or upper decks from one entrance.

[0003] Typically, the entry areas of a passenger transport vehicle are located above the vehicle's axles, so that the height of the entry areas is raised relative to the lower floor.

[0004] Document DE 295 07 057 U1 shows a double-decker rail vehicle with low-floor entrances. The boarding area is accessible via entrance doors on both sides, while the lower level is accessible via floor transitions. The upper level can be accessed from the boarding area via stairs. Seats on the upper level are arranged longitudinally above the boarding area. Behind these seats are the floor and ceiling air ducts of the upper level, as well as all air ducts of the lower level. Disadvantages of the state of the art

[0005] Previously known solutions sometimes make access to the lower or upper levels difficult from the entry area. Furthermore, the passenger transport vehicle's full space is not utilized for seated passenger transport. Problem

[0006] An object of the present invention is therefore to provide an improved passenger transport vehicle for transporting passengers, wherein in particular easy accessibility is to be ensured while at the same time having a high passenger transport capacity. Inventive solution

[0007] The above object is achieved by a passenger transport vehicle according to claim 1 and by a rail vehicle according to claim 15. Further embodiments of the invention emerge from the dependent subclaims.

[0008] According to one embodiment, the passenger transport vehicle has a car body mounted on at least two axles. In particular, according to one refinement of the embodiment, the axles can be arranged in bogies, so that the passenger transport vehicle is designed as a rail vehicle. It is irrelevant whether the bogies, in the form of so-called Jacobs bogies, serve to additionally support another car body or exclusively the one car body of the one rail vehicle.

[0009] Furthermore, the car body is structured as follows: vertically, single-decker car sections are located essentially vertically above an area of the axles or above an area of the bogies, while longitudinally, between the single-decker car sections, a double-decker car section with a lower deck and an upper deck is provided. According to one embodiment, the car body is thus not entirely double-decker. Since the axles of the passenger transport vehicle can, for example, be provided longitudinally at the end areas of the car body, these end areas are preferably single-decker.

[0010] The lower level thus provided has two entry areas for side passenger entry, spaced apart from each other in the longitudinal direction of the passenger transport vehicle, with a first passenger area provided longitudinally between the entry areas. This ensures that access to the first passenger area is possible simultaneously via two entry areas, in particular from the same side of the vehicle, thereby accelerating the boarding and disembarking process. For this purpose, the entry areas each have at least one door device.

[0011] The term "passenger area" is to be understood as being suitable for accommodating passengers comfortably for extended periods of time. In particular, a passenger area has seating arrangements so that a passenger does not have to spend the entire journey in a reclining position. In contrast, the term "boarding area" means that a door arrangement is mandatory, with the primary purpose of an boarding area being to allow passengers to access a passenger area of the vehicle from outside the vehicle.

[0012] The upper floor comprises a second passenger area, a third passenger area, and a fourth passenger area. According to one embodiment, the entire upper floor is arranged substantially vertically directly above the boarding areas and the first passenger area. The second and third passenger areas of the upper floor are provided substantially directly above the boarding areas. The fourth passenger area lies longitudinally between the second and third passenger areas, with the fourth passenger area thus being arranged substantially above the first passenger area of the lower floor.

[0013] This arrangement means that not only the first passenger area on the lower level and the fourth passenger area on the upper level can be used to transport seated passengers, but also the third and fourth passenger areas above the boarding areas can be used for this purpose.

[0014] Furthermore, the boarding areas and door mechanisms are essentially at a similar height to the first passenger area on the lower level—however, a slight height difference is possible and may even be advisable—so that access to the first passenger area via the boarding area is facilitated. For clarification, if boarding areas were arranged in an area above the axles according to the state of the art, a relatively large height difference would have to be overcome to reach the passenger area from the boarding area.

[0015] According to one embodiment of the invention, the car body comprises a staircase device which is designed in such a way that access is ensured from an entry area to the upper floor and to the single-story car sections.

[0016] According to a further embodiment, the first and / or fourth passenger area can be constructed as so-called transverse seating areas, whereas the second and third passenger areas above the entry areas on the upper deck are designed as longitudinal seating areas. The differentiation as a transverse seating area or longitudinal seating area is based on the arrangement of a predominant proportion of the existing seating devices for passengers: in a transverse seating area, the seating direction of the passengers is predominantly oriented in or against the direction of travel or in the longitudinal direction, in particular the seating devices are designed as double seats with two seats next to each other. The longitudinal seating area, on the other hand, predominantly comprises seating devices whose seating direction is oriented essentially transversely to the direction of travel or in the transverse direction of the passenger transport vehicle.

[0017] In particular, the first passenger area may have, in addition to the seating, areas without seating - or with folding seats - which are specifically reserved for wheelchairs, for storing luggage or for bicycles.

[0018] According to a further embodiment, the seating devices of the second and third passenger areas, designed as longitudinal seats, are arranged laterally on the car body in the longitudinal direction. This allows access to the fourth passenger area, in particular designed as a transverse seating area, centrally between the seating devices of the second and third passenger areas.

[0019] In the sense of the above embodiments of the invention, the second and / or third passenger area each comprise seating devices for at least five, in particular for eight persons.

[0020] A basic idea is based on a passenger transport vehicle, whereby the car body - and possibly in conjunction with a position of the axles - is designed so that a floor clearance in the vertical direction between a lateral entry edge of the door device and the top edge of the rail is between 720 and 780 mm, particularly preferably 760 mm. In this way, for the first time, access to the entry area of the passenger transport vehicle can take place on the majority of platforms at essentially the same or a similar height. It has been found that - contrary to expert assumptions - with an advantageous design of the car body it can be more sensible to adapt the height of the entry area of a passenger transport vehicle to the height level of a platform, instead of providing steps or ramps to bridge the height difference.

[0021] According to the invention, the first passenger area comprises a first passenger floor, wherein the first passenger floor is lower in the vertical direction than an entry floor of the entry area. In order to get from the entry area to the first passenger area - or vice versa - a height difference must be overcome, even though both areas are located on the lower level. This different arrangement of the floors means that the space available in the cross-section of the car body can be used particularly efficiently; in particular, a larger vertical installation space is thus available for the first passenger area on the lower level and for the fourth passenger area on the upper level. At the same time, the arrangement of the entry area comprising an entry edge located at the advantageous above-mentioned height level is enabled.

[0022] According to the invention, a so-called first vertical distance between the entry floor and the first passenger floor in the vertical direction is between 100 and 250 mm, preferably between 100 and 170 mm, in particular 123 or 147 mm.

[0023] According to a further, additional, or alternative embodiment, the first passenger floor is arranged vertically lower than the entry edge of the door device. Thus, a height difference must be overcome to reach the level of the first passenger floor from the entry edge. Accordingly, the entry area can have a slope leading from the height of the entry edge to the height of the first passenger floor.

[0024] According to the invention, the second passenger area is provided with a second passenger floor, the third passenger area with a third passenger floor, and the fourth passenger area with a fourth passenger floor. The fourth passenger floor is arranged lower in the vertical direction than the second passenger floor and / or than the third passenger floor. The fourth passenger floor is therefore at a lower height than the second and / or third passenger floor. This measure also contributes to the particularly efficient use of the installation space of the car body in the cross-sectional direction. In particular, this makes it possible to provide a minimum height of 1950 mm for the fourth passenger area while simultaneously arranging supply facilities in an installation space in a central region of the ceiling above the fourth passenger area.Furthermore, the fourth passenger area is designed to have a central area with fourth minimum dimensions in the transverse direction. These fourth minimum dimensions comply with the TSI regulations (European Union Technical Specifications for Interoperability in Rail Transport).

[0025] According to the invention, a second vertical distance between the second passenger floor and the fourth passenger floor and / or a third vertical distance between the third passenger floor and the fourth passenger floor is between 50 and 200 mm, preferably between 80 and 150 mm, in particular 107 mm.

[0026] Expanding on this basic principle, the invention proposes a stepless transition between the entry floor and the first passenger floor. This makes it particularly easy to access the first passenger area from the entry area. This simplification benefits, for example, people with walking difficulties and / or allows heavy, rollable luggage to be transported particularly easily into the first passenger area.

[0027] According to one embodiment of the aforementioned extension, a ramp is provided between the entry floor and the first passenger floor, by means of which the difference in height between the entry floor and the passenger floor can be overcome without steps. For example, this ramp can be inclined at a first angle of less than 10°, in particular 8.5°, relative to a horizontal line.

[0028] An alternative extension of this basic principle proposes providing a step at the transition between the entry floor and the first passenger floor. This allows the transition to be designed with essentially horizontal surfaces.

[0029] According to a further embodiment, a transition(s) between the second passenger floor and the fourth passenger floor and / or between the third passenger floor and the fourth passenger floor is / are equipped with a second and / or a third ramp, so that a height difference between these passenger floors can be overcome without steps. Preferably, the second and / or third ramp is / are inclined relative to the horizontal at a second angle of less than 10°, in particular less than 8.5°, preferably by 7°. The presence of the ramp(s) at the transition between the fourth passenger area and the second and / or third passenger area is particularly advantageous for the spatial design of the car body.This prevents a passenger from experiencing an abrupt change in height when crossing these transitions, which could potentially result in the passenger's head colliding with part of the ceiling on the upper level. The stepless transition on the upper level thus reduces the risk of injury for passengers.

[0030] According to a further embodiment, the entry floor of the entry area is arranged at a lower height than the entry edge. In particular, the entry floor is limited to a central floor section of the entry area. According to a special embodiment, a slope is provided between the entry edge and the lower entry floor to ensure a smooth transition from the entry edge on the door device to the entry floor.

[0031] The measures described above for creating step-free transitions or a step-free slope in the lower level ensure good barrier-free access to the lower level, so that wheelchairs, suitcases, bicycles, etc. can reach the first passenger area particularly easily.

[0032] According to a further embodiment, the second and / or third passenger area can be designed such that installation space for supply devices is provided in an area between a lateral wall of the car body and the seating devices. This means that this installation space is designed such that cables, air conditioning ducts, hoses, functional components, or other devices for operating the passenger transport vehicle can be arranged therein.

[0033] In addition to the above embodiment, according to a further embodiment, the car body and the interior fittings of the car body in the region of the second and / or third passenger area can be designed such that no relevant installation space for utility equipment, such as air conditioning ducts, is available in a central region of the ceiling of the second and / or third passenger area. Thus, the entire cross-section, in particular the height, of the car body is utilized for efficient passenger transport. This is particularly advantageous if the second passenger floor and / or the third passenger floor is / are located at a higher level than the fourth passenger floor. The central section of the second and / or third passenger area thus also complies with the TSI requirements.

[0034] Additionally or alternatively, the car body and interior design in the area of the fourth passenger area can be selected so that space is available for utility equipment in a central area of the ceiling of the fourth passenger area. In conjunction with the aforementioned design, utility equipment in the area of the second and third passenger areas can be provided laterally on a wall area of the car body, which are then transferred centrally to the ceiling at the transition to the fourth passenger area. This is particularly desirable if lateral luggage racks are provided in the ceiling area of the fourth passenger area.

[0035] According to one embodiment, the car body is constructed in the area of the entry area such that a lateral door area - i.e., a lateral section of the entry area in the immediate vicinity of the door device - is vertically higher than a central area of the entry area - i.e., a central section of the entry area above the central entry floor. This can be achieved, for example, by the third and / or fourth passenger floor having a support structure with a downwardly curved cross-section. This can reduce the risk of injury for taller passengers who may enter the passenger transport vehicle through the door device with a swing from a platform higher than the entry edge.

[0036] According to a further embodiment, the door devices and / or the entry areas for boarding and disembarking the passenger transport vehicle are not arranged above an axle and / or a bogie. In other words, the height of the entry edge and / or the entry floor is lower than the vertically upper edge of a wheel guided on the axle. It should be clarified that door devices may well be provided in an area above an axle or above a bogie, whereby these door devices are exclusively suitable for accessing another passenger transport vehicle adjoining the passenger transport vehicle.

[0037] By designing the passenger transport vehicle according to one or more of the described embodiments and / or configurations, it is ensured that the boarding areas have first minimum dimensions, and the second, third, and fourth passenger areas each have second minimum dimensions, third minimum dimensions, and fourth minimum dimensions, with all minimum dimensions complying with the provisions of the European Union's Technical Specifications for Interoperability (TSI) for rail transport. This ensures that an average-sized person is provided with sufficient space for movement in the boarding areas and the aisle areas of the second, third, and fourth passenger areas.

[0038] It is further disclosed that the entry area, in the effective proximity of the door mechanism, has a downward-leaning step and / or a sliding step. The sliding step can serve, on the one hand, to bridge any gap that may exist between the platform and the vehicle and / or, on the other hand, can be designed such that a wheelchair can be moved into the passenger transport vehicle from a platform edge essentially without external lifting.

[0039] Furthermore, locating a restroom on the lower level is advantageous, especially if it is designed for people with disabilities. This ensures that—unlike locating a restroom on the upper level—every passenger can reach the restroom regardless of their physical abilities.

[0040] It is particularly advantageous to design one or more embodiments of the described passenger transport vehicle as a rail vehicle, in particular as a wagon and / or railcar.

[0041] The embodiments described above can be combined with each other in any way that makes sense. Short description of the characters

[0042] The accompanying drawings illustrate embodiments and, together with the description, serve to explain the principles of the invention. The elements of the drawings are relative to one another and are not necessarily to scale.

[0043] The same reference numerals indicate similar parts. Fig. 1 shows a side view of a rail vehicle, Fig. 2 a horizontal section through the lower deck of the rail vehicle according to Fig. 1 , Fig. 3a horizontal section through the upper deck of the rail vehicle according to Fig. 1 , Fig. 4 a section in side view with openings on the door device of the rail vehicle according to Fig. 1 , Fig. 5 a cross-section through the rail vehicle according to Fig. 1 according to AA, and Fig. 6 a cross-section through the rail vehicle according to Fig. 1 according to BB. Examples of implementation

[0044] The Fig. 1 The passenger transport vehicle shown is designed according to one embodiment as a rail vehicle 1 and is shown in a side view.

[0045] The Figures 2 to 6 provide further views of the embodiment of the passenger transport vehicle. Figures 1 to 3 the basic division of rail vehicle 1 is illustrated.

[0046] As in Fig. 1As shown, the rail vehicle 1 consists, among other things, of two bogies 68 and a car body 3 mounted thereon, wherein the bogies 68 each have two axles 2. The axles 2 in turn comprise two wheels, over which the rail vehicle 1 is guided on rails 65.

[0047] With regard to the rail vehicle 1, a transverse direction 60, a longitudinal direction 59 and a vertical direction 62 are defined, whereby the information used below, such as "vertical", "transverse", "lateral", "higher" and "lower", are to be interpreted with reference to these directional information.

[0048] The car body 3 of the rail vehicle 1 can be divided into two single-decker car sections 4 and one double-decker car section 5, with the bogies 68 located below the single-decker car sections 4. The double-decker car section 5 projects downwards beyond the upper edge of the wheels of the bogie 68 in the vertical direction 62.

[0049] The double-decker carriage section 5 has a lower level 6 and an upper level 7, with the lower level 6 being divided into two boarding areas 50 and a first passenger area 10 located in the longitudinal direction 59 between the boarding areas 50 (see also Fig. 2 ), and the upper floor 7 is divided into a second passenger area 20, a third passenger area 30 and a fourth passenger area 40. As in Fig. 3 As can be seen, the fourth passenger area 40 is located in the longitudinal direction 59 between the second passenger area 20 and the third passenger area 30.

[0050] The single-level carriage sections 4 each have a passage 63 through which a passenger can transfer from one rail vehicle 1 to another, adjacent rail vehicle. Lateral exit from the rail vehicle—for example, onto a platform—is not possible via the passage 63. Furthermore, a staircase 15 is provided, which provides access from the boarding area 50 to the single-level carriage sections 4 and to the upper deck 7.

[0051] The entry area 50 comprises a door device 54, preferably designed as a sliding door, which enables entry and exit into the rail vehicle 1. Fig. 5the detailed design of the entry area 50 becomes clear. The entry area 50 further has an entry edge 55 in a lateral door area 56, wherein the car body 3 and the entry area 50 are designed such that the height level in the vertical direction 62 of the entry edge 55 approximately corresponds to the height level of a platform 62. For this purpose, the car body - if necessary in interaction with a position of the axles 2 and the wheels - is designed such that a floor clearance 53 in the vertical direction 62 between a lateral entry edge 55 of the door device 54 and a rail top edge 65 is between 720 and 780 mm, particularly preferably 760 mm.

[0052] An entry floor 51 of the entry area 50 has a lower height level than the entry edge 55, with a slope 52 being arranged between the entry floor 51 and the entry edge 55.

[0053] Furthermore, an extendable sliding step 58 can be provided under the floor of the entry area 50 to bridge a gap between the rail vehicle 1 and the platform edge 62.

[0054] In Fig. 5 Furthermore, the third passenger area 30 with a third passenger floor 31 is shown in cross-section, wherein the third passenger floor 31 has a cranked support structure 32 in cross-section. As a result, the effective height in the lateral door area 56 of the entry area 50 is greater than the effective height in a central area 57 of the entry area 50. The central area 57 is designed with first minimum dimensions 67, ensuring sufficient height for the majority of passengers and meeting the TSI requirements.

[0055] The second passenger area 20, not shown, essentially corresponds to the one in Fig. 5 shown third passenger area 30. From Fig. 5It can be seen that the seating devices 25 are designed as longitudinal seats, so that a passenger would sit thereon transversely to the longitudinal direction 59. Behind the seating devices 25 - between a backrest and a wall 28 of the car body 3 - in the second and / or third passenger area 20 / 30, an installation space 26 extending in the longitudinal direction 59 is provided for accommodating vehicle components, for example, air conditioning ducts, cable harnesses, etc. In addition, a drive 66 for the automatic operation of the door device 54 is provided below the installation space 26.

[0056] Furthermore, Fig. 5 the special and efficient use of the cross-section of the two-story carriage section 5 of the carriage body 3 can be seen (section AA from Fig. 1). By eliminating any space-consuming cross-sections in a central region of the ceiling of the car body 3, a central region of the second and / or third passenger area 20 / 30 in the transverse direction has second / third, TSI-compliant minimum dimensions 27 / 37 in cross-section. This means that a central region of the ceiling of the car body 3 in the transverse direction 60 is designed to be as thin as possible, for example, it only has load-bearing structures for supporting the vehicle loads, insulation and cladding elements, possibly lighting elements, and possibly thin cables. Furthermore, installation space 29 can be provided essentially directly vertically above the seating devices 25.

[0057] Fig. 6 describes the structure of the double-decker car section 5 of the car body 3 according to the section line BB from Fig. 1. In the lower level 6, the first passenger area 10 is located, comprising a first passenger floor 11 with seating devices arranged thereon, designed as transverse seats 16. The first passenger floor 11 is lower than the entry floor 31, with a first vertical distance 13 in the vertical direction 62 being present between the two floors, which is, for example, 123 or 147 mm (see Fig. 5 and Fig. 6 ). This first vertical distance 13 can be overcome, for example, by a ramp 12 (see Fig. 4 ), wherein the ramp 12 is inclined at a first angle 14 relative to a horizontal 61, and the first angle 14 is in particular less than 10°, in particular less than 8.5°.

[0058] Devices 18 for storing luggage can be arranged in the area of a ceiling of the first passenger area 10.

[0059] Furthermore, a fourth passenger floor 41 of the fourth passenger area 40 is spaced apart in the vertical direction 62 by a second vertical distance 23 from a third passenger floor 31 of the third passenger area 30, wherein this second vertical distance 23 can be in particular 107 mm (see Fig. 5 and Fig. 6 ). The fourth passenger floor 41 is at a lower height than the second passenger floor 21 of the second passenger area 20 and / or the third passenger floor 31 of the third passenger area 30.

[0060] Ramps 22 are therefore provided between these passenger areas so that the described height difference can be overcome without steps. Preferably, the second and / or third ramp 22 is / are inclined relative to the horizontal 61 at a second angle 24 of less than 10°, preferably less than 7°.

[0061] In contextual reference to the above - but without necessarily adopting the details of the described embodiments - it is noted that the entry floor 51 and the second and third passenger floors 20 and 30 are each located in the vertical direction 62 above the first passenger floor 11 and the fourth passenger floor 41.

[0062] In particular, Fig. 1 It can be seen that the entirety of the floors in the longitudinal direction 59, ie the entry floors 51 with the first passenger floor 11, and further the third and fourth passenger floors 21 and 31 with the fourth passenger floor 41, have a slightly pronounced U- or V-shape, and the first passenger area 10 and the fourth passenger area 40 are lowered compared to the entry floors 51 and the second and third passenger floors 21 and 31.

[0063] Furthermore, Fig. 6 and Fig. 3It can be seen that the fourth passenger area 40 has transverse seats 43, and that a space 44 for supply lines, air conditioning ducts, or other components is provided on the underside of the ceiling of the car body 3. Due to the arrangement of the space 44, luggage racks 48 can be arranged above the transverse seats 43 in the fourth passenger area 40.

[0064] Furthermore, the fourth passenger area 40 and the fourth passenger floor 41 are designed such that an aisle area between the transverse seats 43 has fourth, TSI-corresponding minimum dimensions 47.

[0065] Although specific embodiments have been illustrated and described herein, it is within the scope of the present invention to appropriately modify the illustrated embodiments without departing from the scope of the present invention.
