Definitions
- the invention is in the area of vehicle engineering and in particular rail vehicle engineering and relates to a rail vehicle having a ventilation duct which is incorporated in part into a luggage rack.
- the invention relates to the luggage rack module for constructing a luggage rack.
- Rail vehicles have ventilation devices in order to direct inlet air into the passenger compartment and to remove exhaust air out of the passenger compartment. Ventilation ducts which, however, have a certain space requirement as a result of the necessary cross section, are necessary for this purpose.
- US 6,241,186 B1 describes a luggage rack module for constructing a luggage rack from holding arms which are fastened to the ceiling of the rail vehicle extending vertically and profile plates which are held by the holding arms. The profile plates are also fastened on the interior panelling of the rail vehicle and a ventilation duct is defined between said profile plates and the interior panelling. Further luggage racks are described in EP 1 442 935 A1 and US 3 355 210 .
- US 2 383 423 A discloses an air purifying and conditioning system for passanger vehicles.
- EP 0 182 433 A1 describes a method for adjusting the temperature in a passanger room of a vehicle.
- EP 0 114 981 A2 discloses an apparatus for air conditioning of a vehicle using channels arranged in the ceilings of the vehicle.
- GB 1 316 429 A describes a ventilating system for passanger vehicles.
- WO 2005/052459 A2 and DE 20 2006 010 428 U1 describe air conditioning systems for a vehicles.
- a rail vehicle having at least one longitudinal ventilation duct which extends in the longitudinal direction of the rail vehicle is proposed.
- the ventilation duct when viewed in vertical cross section, extends from a region between interior panelling of the rail vehicle and a carbody shell of the rail vehicle above a luggage rack as far as into the region of the luggage rack, wherein the ventilation duct runs in part through base supports of the luggage rack which are spaced apart from one another in the longitudinal direction of the rail vehicle and are fastened on the carbody shell.
- a ventilation device which enables improved air conduction can be constructed as a result.
- the air speed inside the ventilation duct can be reduced with the air flow per unit time remaining constant, which leads to a reduction in noise development and to reduced pressure losses.
- the present idea consequently solves the inconsistency between the necessary cross section and the limited space available by lengthening the ventilation channel, which extends in the ceiling, or above ceiling panelling, in the side region of the rail vehicle by creating an additional volume for conducting the air in the region of the luggage rack or the luggage compartment.
- the base supports or base support elements are, for example, the side arms of the luggage rack, by way of which said luggage rack is fastened on the carbody shell.
- the luggage rack then has at least two, typically several base support modules which are arranged adjacent to one another in the longitudinal direction.
- the ventilation duct when viewed in vertical cross section, is constructed from one upwardly open first hollow chamber formed by individual hollow chamber segments, which extend between the base supports, or base support elements, of the luggage rack, and one downwardly open second hollow chamber above the luggage rack, wherein the base supports (base support elements) have through-openings for connection of the hollow chamber segments.
- the hollow chamber segments can be held by the base supports or the base support module.
- the construction of the ventilation duct from the two hollow chambers allows for simple assembly.
- the second hollow chamber can be realized as part of the interior panelling of the ceiling or can be mounted on the ceiling.
- the installation of the first hollow chamber is effected with the installation of the individual luggage rack modules which include the first hollow chamber which is supported by the base supports.
- the second hollow chamber is thus connected fixedly to the carbody shell, whilst the first hollow chamber is supported by the luggage rack and is mounted together with said luggage rack.
- the hollow chambers can be completely open on their sides facing one another, i.e. in the form of shells or half-shells. It is also possible for the hollow chambers, or even just one of the two hollow chambers, to have walls with large openings on their sides facing one another such that overall a ventilation duct with an effective cross section is formed.
- the hollow chambers can be produced from comparatively thin material since - in the case of the first hollow chamber - as part of the luggage rack they do not have to support loads. Said function is assumed by the base supports or the base support module. As a result, the weight of the hollow chambers can be comparatively light.
- two longitudinal ventilation ducts are arranged parallel to one another in the longitudinal direction of the rail vehicle, each of which is constructed from a first upwardly open hollow chamber and a second downwardly open hollow chamber, wherein the first hollow chambers each can comprise or can consist of individual hollow chamber segments which are connected together directly or by means of the base supports.
- the base supports of the luggage rack support, for example, a hollow profile with two chambers for the hot air and return air.
- the hollow chambers incorporated into the luggage racks can also be understood as part of a ventilation connection between the hollow chamber segments which extend in the ceiling regions and the interior of the passenger compartment.
- the hollow chambers incorporated into the luggage rack also allow for an air flow in the longitudinal direction of the rail vehicle through the base supports.
- the hollow chambers in the luggage rack consequently fulfil two functions. On the one hand, they enlarge the effective cross section of the ventilation ducts and, on the other hand, they provide the connection to the passenger compartment.
- the sealing between the hollow chambers which form a common ventilation duct can be effected by suitable sealing means, for example rubber seals based on EPDM (ethylene-propylene-diene-monomers).
- suitable sealing means for example rubber seals based on EPDM (ethylene-propylene-diene-monomers). This also simplifies the assembly of the luggage rack and the joining of the hollow chambers. Additional connecting pieces between the hollow chambers are not necessary, but can be provided where required.
- the hollow chamber segments can be comprised of or can consist of sheet metal, a plastics material or a composite material. Said materials are comparatively light and are easy to work.
- the hollow chamber segments are sealed on the base support.
- EPDM-based seals are suitable here too as are other sealing materials, such as silicon.
- the longitudinal ventilation duct or the longitudinal ventilation ducts or part or all of the hollow chamber segments have downwardly pointing openings which enable connection to vertically extending side wall ducts.
- the side wall ducts which can also be designated as branch ducts, conduct the air from one of the ventilation ducts for example to the floor region of the passenger compartment.
- the sealing between the side wall ducts and the ventilation ducts can be effected in this case too using suitable sealing means, it being possible to dispense with additional connecting pieces, for example intermediate ducts.
- suitable sealing means it being possible to dispense with additional connecting pieces, for example intermediate ducts.
- the use of EPDM-based seals or other sealing means simplifies assembly since there is no requirement for hose clips or the like.
- the vertically extending side wall ducts are realized between interior panelling of the rail vehicle and panelling which extends between the interior panelling of the rail vehicle and the carbody shell.
- the side wall ducts can thus be constructed from two half-shells and can be defined simply by the "inner" form of the pieces of panelling facing one another.
- the longitudinal ventilation duct or part or all of the hollow chamber segments have downwardly pointing exhaust air openings which open out into the passenger compartment of the rail vehicle on the bottom side of the luggage rack.
- the hollow chamber segments provide a direct connection to the passenger compartment by means of the exhaust air openings which are realized on the bottom side of the luggage rack. Consequently, the hollow chamber segments form, so to speak, a connecting element between the passenger compartment and the ventilation duct which extends in the ceiling region as well as an extension of the effective cross section of the ventilation duct.
- two longitudinal ventilation ducts are arranged parallel to one another in the longitudinal direction of the rail vehicle, wherein the first ventilation duct is passed through by cross ducts in which the base supports, or a top arm of the same, extend.
- the second ventilation duct is constructed from a first upwardly open hollow chamber and a second downwardly open hollow chamber.
- the first hollow chambers can comprise or can consist of individual hollow chamber segments which are connected together directly or by means of the base supports.
- the first ventilation duct can be mounted, for example, completely in the ceiling region of the rail vehicle, it extending, however, in the vertical direction as far as into the region in which the luggage rack is mounted.
- the first ventilation duct extends as far as over fastening elements for fastening the luggage rack on the carbody shell and covers said fastening elements. So that the luggage rack is nevertheless able to be fastened on the carbody shell, the first ventilation duct has cross ducts, through which the base supports, or parts thereof, are able to be guided in order to be moved into engagement with the fastening elements.
- the first ventilation duct is fastened on the carbody shell, but not on the luggage rack.
- the second ventilation duct is supported at least in part by the luggage rack.
- the first or lower hollow chamber is formed in this case by the hollow chamber segments which are fixed on the base.
- a luggage rack module for constructing a luggage rack of a rail vehicle.
- the luggage rack module has two base supports, which are spaced apart from one another, with fastening elements for fastening on a carbody shell of the rail vehicle, wherein the base supports have in each case at least one opening.
- At least one hollow chamber segment which is open toward a top side of the luggage rack, extends between the spaced-apart base supports and is held in a sealed manner on its respective end face on the respective base support, wherein the hollow chamber segment, when viewed in the longitudinal direction, is open and surrounds the openings in the base support by way of its respective end face.
- the luggage rack module assumes several functions. On the one hand, it serves as supporting means for the luggage compartment, i.e. the base support, for example the side arms, absorb the loads occurring during normal use by the passengers and directs them into the carbody shell. Moreover, the luggage rack module enlarges the available cross section for the ventilation duct by a ceiling duct being extended by means of the hollow chamber segments as far as into the region of the luggage rack.
- the mounting of the luggage rack modules is effected, for example, along a modular dimension which is provided, for example, by the window dividers.
- the luggage rack modules can be pre-assembled and then fastened on site in the rail vehicle.
- the modular construction enables rapid assembly and, where applicable, removal and repair since it is possible to exchange individual modules.
- the hollow chamber segment has on its bottom side, at least one opening through which the air is able to flow into the hollow chamber segment or out of the hollow chamber segment.
- the hollow chamber segments consequently also assume the function of distributing air through the openings.
- the openings can open out, for example, directly into the passenger compartment.
- the openings provide exhaust air openings.
- the openings can also enable cross connection to further ducts, for example ducts along the side wall of the rail vehicle in order to conduct the air (inlet or exhaust) into or out of other regions of the passenger compartment.
- the hollow chamber segment has the function of conducting the air flow in the longitudinal direction of the rail vehicle, the air flow in this case flowing through the base supports or side arms, and distributing it in a cross direction thereto.
- the hollow chamber segment is defined on its top side by a wall with openings.
- the hollow chamber segment is connected by means of the openings to a top, downwardly-open hollow chamber of the ceiling duct. Together they form the ventilation duct.
- the hollow chamber segment can also be realized without a top wall.
- the luggage rack module has two hollow chamber segments which extend parallel to one another and are separated from one another. Consequently, it is possible to extend two ceiling ducts to construct ventilation ducts which are enlarged in cross section.
- one of the two hollow chamber segments is defined by a bottom wall which curves in part as far as below the other hollow chamber segment.
- the bottom wall allows one of the two ventilation ducts to be realized downwardly in the desired form, for example in order to be able to place outlet openings in a suitable manner. If the bottom wall defines, for example, an exhaust duct and if this is not arranged directly on the side wall of the rail vehicle, the curvature for example in the direction of the side wall makes it possible for the exhaust air to be able to be removed where possible from the direct vicinity of the side wall, for example above the window. This is desired for both reasons of ventilation and of convenience.
- the luggage rack module includes at least one holder for at least one of the following elements: indirect lighting, loudspeaker, seat notices.
- the luggage rack module consequently fulfils even more functions and can additionally also support cabling.
- the luggage rack module includes a base support module formed by the two base supports, which are spaced apart from one another and extend parallel to one another, in the form of side arms which are rigidly connected together by means of at least one longitudinal support. Consequently, a framework is constructed which supports the further components of the luggage rack module and can be fastened on the carbody shell.
- the base supports together with the hollow chamber segment or segments can be realized such that they assume the following functions.
- FIG 1 shows a cross section through a schematic representation of a ventilation device of a rail vehicle according to one embodiment.
- a base support 31 of a luggage rack 30 is fastened on a carbody shell 100 of the rail vehicle.
- the luggage rack 30 includes two base supports 31, which are spaced apart from one another, secured on the carbody shell 100 and can also be designated as side arms.
- the base supports 31 absorb the loads typically occurring and direct them into the carbody shell 100.
- the base supports can have suitable fastening elements such as, for example, flanges or hook elements, by way of which they are fastened either directly on the carbody shell 100 or on supporting means which are secured on the carbody shell 100. Concrete examples are shown in Figures 4 to 8 .
- the base supports 31 have two through-openings 32 on their ends pointing to the carbody shell 100.
- a first longitudinal ventilation duct which extends in the longitudinal direction of the rail vehicle, in the present exemplary embodiment this is a first and a second ventilation duct 10 and 20, is/are arranged above the luggage rack 30.
- the ventilation ducts 10, 20 extend in the vertical direction as far as into the region of the luggage rack 30.
- the two ventilation ducts 10, 20 extend up to approximately the bottom side of the base support 31 of the luggage rack.
- the vertical extension of the two ventilation ducts downward is approximately the same, however it can be different.
- the ventilation ducts 10 and 20, particularly the bottom region of the ventilation ducts 10 and 20, extends in the longitudinal direction through the luggage rack 30 such that the ventilation ducts 10, 20 extend in part through the base supports 31 of the luggage rack 30.
- the top region of the ventilation ducts 10, 20 extends in the longitudinal direction of the rail vehicle between interior panelling 105 of the rail vehicle interior and the carbody shell 100.
- the interior panelling 105 of the rail vehicle can define or delimit at least one of the two ventilation ducts 10, 20 directly with respect to the passenger compartment and form part of the walls of the ventilation ducts.
- the ventilation ducts 10, 20 in the embodiment shown here when viewed in cross section, are in each case constructed from one upwardly open first hollow chamber 11, 21 produced from individual hollow chamber segments 11a, 21a, which extend in each case between the base supports 31 of the luggage rack 30, and one downwardly open second hollow chamber 12, 22 above the luggage rack 30.
- the base supports 30 In order to enable an air flow in the longituidnal direction in the region of the luggage rack 30, the base supports 30 have the through-openings 32 for connection of the hollow chamber segements 11a, 21a.
- Figures 2 and 3 show longitudinal cross sections through the ventilation ducts.
- Figure 2 in this case, corresponds to a longitudinal section which extends approximately along the downwardly pointing arrow in Figure 1 .
- Figure 3 in contrast, corresponds to a longitudinal section which extends approximately along the upwardly pointing arrow in Figure 1 .
- the base supports 31 consequently support the first (bottom) hollow chambers 11, 21 of the ventilation ducts 10 and 20.
- the top part of the respective ventilation duct 10, 20 above the luggage rack 30 can be formed, for example, in part by ceiling panelling elements or shell elements. These can be formed integrally together with the ceiling panelling, which is part of the panelling of the rail vehicle 105, or can comprise or can consist of individual elements connected together. Together they form the second hollow chambers 12, 22, which are open on their bottom side and extend in the longitudinal direction of the rail vehicle. The bottom side does not have to be completely open. It is sufficient for it to have openings, for example large longitudnal openings, over wide regions.
- the bottom part of the respective ventilation ducts 10, 20 extends through the region of the luggage rack 30 which points to the carbody shell 100 and is formed there by the individual hollow chamber segments 11a, 21a which in each case extend between two adjacent base supports 31.
- the hollow chamber segments 11a, 21a together provide the first or bottom hollow chamber 11, 21.
- the hollow chamber segments 11a, 21a are connected together in the longitudinal direction by means of the base supports 31 of adjacent luggage rack modules. Sealing is effected, for example, between the base supports 31 of adjacent luggage rack modules such that continuous longitudinal hollow chambers are formed.
- An air flow into the first hollow chambers 11, 21 is made possible in the longitudinal direction (lengthwise direction) by the through-openings 32 in the base supports 31, in this case a large through-opening 32 being associated in each case with a first hollow chamber 11, 21. If the stability and carrying force of the base support 31 is to be increased, it is possible to adapt the cross section of the openings 32 in a corresponding manner or to provide several smaller openings.
- the overall cross section of the through-openings should ideally then be adapted in such a manner that a good longitudinal airflow is made possible.
- the first hollow chambers 11, 21 together with the second hollow chambers 12, 22 form the respective ventilation ducts 10 and 20.
- the first and second hollow chambers associated with one another are connected together in a sealed manner on longitudinal edges such that closed ventilation ducts are created.
- Each ventilation duct 10, 20 can comprise or can consist of one top and one bottom half shell, the term "half shell" not necessarily having to be understood in the mathematical sense.
- the cross section of the respective ventilation ducts 10, 20 is enlarged.
- the flow speed of the inlet and exhaust air can be reduced whilst the air flow volume per unit time remains the same, which has a favourable effect on the noise development and the maintaining of the pressure.
- the first ventilation duct 10 which is adjacent the carbody shell 100 in the embodiment shown in Figures 1 and 2 , provides a hot air duct.
- Said hot air duct is connected on its bottom side to side wall ducts 40 which extend laterally next to windows 110 and by means of which the hot inlet air can be directed into the bottom region of the passenger compartment, for example into the floor region.
- the first ventilation duct 10 or the hollow chamber segments 11a has/have downwardly open openings 14 which make connection to the vertically extending side wall ducts 40 possible. This is shown in a more precise manner in Figure 5 .
- Suitable sealing materials for example based on EPDM, can be used for sealing between the first ventilation duct 10 and the side wall ducts.
- the second ventilation duct 20 which is adjacent the passenger compartment in the embodiments shown in Figures 1 and 3 , provides an exhaust air duct which is connected to the interior of the passenger compartment by means of exhaust air openings 24.
- the exhaust air openings 24, in this case, can be arranged on the bottom side of the luggage rack 30.
- the individual hollow chamber segments 11a, 21a for forming the first hollow chambers 11, 21, as well as the second hollow chambers 12, 22, can be comprised of or can consist of sheet metal, a plastics material or a composite material. Examples are aluminium sheets and flat materials from Recore® or WARO®foam, a material produced from glass-fibre reinforced phenolic foam or melamine foam.
- the first hollow chambers 11, 21 are in direct contact with each of their associated second hollow chambers 12, 22 in. Additional pipe connections or the like are not necessary.
- the hollow chambers are connected together only on their edges which face one another and extend in the longitudinal direction. Suitable sealing materials, for example based on EPDM, can be also be used here for sealing.
- FIGS 4 and 5 show concrete embodiments of a ventilation duct.
- the base supports 31 are suspended in a support plate 113 and fastened on the same.

- the first ventilation duct 10 forms a hot air duct which is designated in Figure 4 by the reference WL.
- the first hollow chamber 11 of the hot air duct is defined by side walls 15, a top wall 17 and a bottom wall 16 which extend between the base supports 31.
- the second ventilation duct 20 forms a return air duct which is designated in Figure 4 by the reference RL.
- the first hollow chamber 21 of the second ventilation duct 20 is defined by side walls 25, a top wall 27 and a bottom wall 26.
- the side wall 15, 25 which extends between the two first hollow chambers 11, 21 can be formed by one common flat element or by two separate flat elements.
- the bottom wall 16 of the first hollow chamber 11 of the first ventilation duct 10 has openings 14 for connection to the side wall ducts 40.
- a flexible duct 41 can produce the connection to the side wall duct 40 and balances out possible tolerances. In addition, better vibration decoupling and sealing is achieved in this manner.
- Connecting openings 18 are provided in the top wall 17 of the first hollow chamber 11 of the first ventilation duct 10. Said connecting openings extend the first hollow chamber 11 upward into the second hollow chamber 12.
- the bottom wall 26 of the first hollow chamber 21 of the second ventilation duct 20 is formed by a profile element produced from thin material which extends in part below the base support 31. On its side pointing to the passenger compartment, the bottom wall 26 engages in a receiving means 25a of the side wall 25 pointing to the passenger compartment and is held there in sealed manner.
- the bottom wall 26 has exhaust air openings 24 in the form of slits. Their downwardly curved form in the direction of the side wall 100 of the rail vehicle makes it possible to realize the exhaust air openings in such a manner that they point away from the passenger compartment toward the side wall of the rail vehicle. As a result, the exhaust air openings 24 are not visible, which is preferred for aesthetic reasons. On the other hand, the return air is removed directly above the window such that a preferred return flow along the window is achieved.
- the second ventilation duct 20 extends in part below the first ventilation duct 10 as a result of the outwardly curved bottom wall 26.
- the bottom wall 26 can additionally receive lighting devices which enable indirect lighting.
- the bottom wall 26 can be formed in a part region such that it forms an indentation 26a which extends in the longitudinal direction.

- the bottom wall 26 can also provide the possibility for accommodating loudspeakers, sensors and cabling.
- the bottom wall 26 covers, in a visual and functional manner, the region of the luggage rack 30 pointing to the carbody shell 100 and serves as a profile above the window.
- the top wall 27 of the first hollow chamber 21 of the second ventilation duct 20 also has connecting openings in order to connect the hollow chambers 21, 22 to one another and to achieve an extension of the second ventilation duct 20.
- the top walls 17, 27, in this case, do not necessarily have to be provided, but are also able to be omitted where necessary.
- First hollow chamber segments 11a, 21a adjacent in the longitudinal direction are connected together by means of the through-openings 32 in the base supports 31.
- the side walls 15, 25, the top walls 17, 27 and the bottom walls 16, 26 are sealed at their respective end faces on the base supports 31 for this purpose.
- the luggage rack 30 can also have a luggage compartment 36 on its bottom side.
- the vertically extending side wall ducts 40 can be realized between interior panelling 121 of the rail vehicle and panelling 122 which extends between the interior panelling 121 of the rail vehicle and the carbody shell 100.
- the panelling 121, 122 in this case, can serve as the half shells of the side wall ducts 40 and are connected together in a suitable manner.
- the hot air or inlet air conducted through the side wall ducts 40 into the floor region passes, for example, into the passenger compartment at the openings 123 which are realized, for example, in the interior panelling 121 of the rail vehicle.
- the individual panelling 121, 122 can be fastened in a hinged manner on the carbody shell 100 or on support elements secured on said carbody shell for example by means of individual hinges or other means such that, in particular, the interior panelling 121 of the rail vehicle, or parts thereof, are able to be hinged up, for example, for the purpose of inspection.
- the second hollow chambers 12, 22 which extend above the luggage rack 30 can comprise or can consist of individual segments which are joined to one another in the longitudinal direction. If, for example, as shown in Figure 4 , further ventilation ducts are provided as well as the hot air duct WL (first ventilation duct) and the return air duct RL (second ventilation duct), the individual segments can have a structure for the construction of said ventilation ducts and at the same time form part of the interior panelling of the rail vehicle in the region of the ceiling.
- an exhaust air duct AL extends above the hot air duct WL and the return air duct RL.
- a ventilation duct CL which is provided for cooling can be realized laterally of and above the return air duct RL.
- each segment in the case of Figure 4 , has four cavities or hollows, the cavities being downwardly open for the return air duct RL and for the hot air duct WL and provide each of the second hollow chambers of said ventilation ducts.
- the two other ventilation ducts AL and CL in contrast, are closed when viewed in cross section. Adjacent ventilation ducts can be separated from one another by means of common intermediate walls.

Description
- The invention is in the area of vehicle engineering and in particular rail vehicle engineering and relates to a rail vehicle having a ventilation duct which is incorporated in part into a luggage rack. In addition, the invention relates to the luggage rack module for constructing a luggage rack.
- Rail vehicles have ventilation devices in order to direct inlet air into the passenger compartment and to remove exhaust air out of the passenger compartment. Ventilation ducts which, however, have a certain space requirement as a result of the necessary cross section, are necessary for this purpose.
- Arranging the ventilation ducts under the floor is known from
JP 2003-095093 A DE 29 911 688 U1 . -
US 6,241,186 B1 describes a luggage rack module for constructing a luggage rack from holding arms which are fastened to the ceiling of the rail vehicle extending vertically and profile plates which are held by the holding arms. The profile plates are also fastened on the interior panelling of the rail vehicle and a ventilation duct is defined between said profile plates and the interior panelling. Further luggage racks are described inEP 1 442 935 A1 andUS 3 355 210 . -
US 2 383 423 A discloses an air purifying and conditioning system for passanger vehicles. -
EP 0 182 433 A1 describes a method for adjusting the temperature in a passanger room of a vehicle. -
EP 0 114 981 A2 discloses an apparatus for air conditioning of a vehicle using channels arranged in the ceilings of the vehicle. -
GB 1 316 429 A -
WO 2005/052459 A2 andDE 20 2006 010 428 U1 describe air conditioning systems for a vehicles. - The previously known solutions, however, are only partly satisfactory as they demand a relatively large amount of space or require expensive assembly. In addition, there is the risk, as in the case of the solution of
US 6,241,186 B1 , that the ventilation ducts become damaged by the loads when the luggage rack is used or the anchoring thereof is affected detrimentally. - Against this background there is a need for accommodating and conducting the air ducts in a space-saving and reliable manner.
- Said object is achieved by a rail vehicle according to Claim 1. In addition, said object is achieved by a luggage rack module according to
Claim 10. Further embodiments, modifications and improvements are produced by way of the following description and according to the accompanying claims. - According to one embodiment, a rail vehicle having at least one longitudinal ventilation duct which extends in the longitudinal direction of the rail vehicle is proposed. The ventilation duct, when viewed in vertical cross section, extends from a region between interior panelling of the rail vehicle and a carbody shell of the rail vehicle above a luggage rack as far as into the region of the luggage rack, wherein the ventilation duct runs in part through base supports of the luggage rack which are spaced apart from one another in the longitudinal direction of the rail vehicle and are fastened on the carbody shell.
- By extending the ventilation duct as far as into the region of the luggage rack the available cross section of the ventilation duct is enlarged. A ventilation device which enables improved air conduction can be constructed as a result. In particular, the air speed inside the ventilation duct can be reduced with the air flow per unit time remaining constant, which leads to a reduction in noise development and to reduced pressure losses.
- The present idea consequently solves the inconsistency between the necessary cross section and the limited space available by lengthening the ventilation channel, which extends in the ceiling, or above ceiling panelling, in the side region of the rail vehicle by creating an additional volume for conducting the air in the region of the luggage rack or the luggage compartment.
- The base supports or base support elements are, for example, the side arms of the luggage rack, by way of which said luggage rack is fastened on the carbody shell. Two side arms together with optional longitudinal supports, which rigidly connect the two side arms which are parallel to one another and spaced apart from one another, form a base support module. The luggage rack then has at least two, typically several base support modules which are arranged adjacent to one another in the longitudinal direction.
- According to one embodiment, the ventilation duct, when viewed in vertical cross section, is constructed from one upwardly open first hollow chamber formed by individual hollow chamber segments, which extend between the base supports, or base support elements, of the luggage rack, and one downwardly open second hollow chamber above the luggage rack, wherein the base supports (base support elements) have through-openings for connection of the hollow chamber segments. The hollow chamber segments can be held by the base supports or the base support module.
- The construction of the ventilation duct from the two hollow chambers allows for simple assembly. Thus, for example, the second hollow chamber can be realized as part of the interior panelling of the ceiling or can be mounted on the ceiling. The installation of the first hollow chamber is effected with the installation of the individual luggage rack modules which include the first hollow chamber which is supported by the base supports. The second hollow chamber is thus connected fixedly to the carbody shell, whilst the first hollow chamber is supported by the luggage rack and is mounted together with said luggage rack.
- The hollow chambers can be completely open on their sides facing one another, i.e. in the form of shells or half-shells. It is also possible for the hollow chambers, or even just one of the two hollow chambers, to have walls with large openings on their sides facing one another such that overall a ventilation duct with an effective cross section is formed.
- The hollow chambers can be produced from comparatively thin material since - in the case of the first hollow chamber - as part of the luggage rack they do not have to support loads. Said function is assumed by the base supports or the base support module. As a result, the weight of the hollow chambers can be comparatively light.
- According to one embodiment, two longitudinal ventilation ducts are arranged parallel to one another in the longitudinal direction of the rail vehicle, each of which is constructed from a first upwardly open hollow chamber and a second downwardly open hollow chamber, wherein the first hollow chambers each can comprise or can consist of individual hollow chamber segments which are connected together directly or by means of the base supports.
- Two, where applicable even several, hollow chambers, which form an extension to the hollow chambers extending above the luggage rack, can be incorporated into the luggage racks in order, in this manner, to enlarge the cross section of the ventilation ducts which are formed by the upper and lower hollow chambers. It is suitable, for example, to extend an inlet air duct and an exhaust air duct as far as into the luggage rack and to incorporate them in part into the same. The base supports of the luggage rack support, for example, a hollow profile with two chambers for the hot air and return air.
- The hollow chambers incorporated into the luggage racks can also be understood as part of a ventilation connection between the hollow chamber segments which extend in the ceiling regions and the interior of the passenger compartment. In contrast to "normal" connections between the ventilation ducts and outlets or inlets from or to the passenger compartment, which essentially only enable a vertical air flow, the hollow chambers incorporated into the luggage rack also allow for an air flow in the longitudinal direction of the rail vehicle through the base supports. The hollow chambers in the luggage rack consequently fulfil two functions. On the one hand, they enlarge the effective cross section of the ventilation ducts and, on the other hand, they provide the connection to the passenger compartment.
- The sealing between the hollow chambers which form a common ventilation duct can be effected by suitable sealing means, for example rubber seals based on EPDM (ethylene-propylene-diene-monomers). This also simplifies the assembly of the luggage rack and the joining of the hollow chambers. Additional connecting pieces between the hollow chambers are not necessary, but can be provided where required.
- According to one embodiment, the hollow chamber segments can be comprised of or can consist of sheet metal, a plastics material or a composite material. Said materials are comparatively light and are easy to work.
- According to one embodiment, the hollow chamber segments are sealed on the base support. EPDM-based seals are suitable here too as are other sealing materials, such as silicon.
- According to one embodiment, the longitudinal ventilation duct or the longitudinal ventilation ducts or part or all of the hollow chamber segments have downwardly pointing openings which enable connection to vertically extending side wall ducts. The side wall ducts, which can also be designated as branch ducts, conduct the air from one of the ventilation ducts for example to the floor region of the passenger compartment. The sealing between the side wall ducts and the ventilation ducts can be effected in this case too using suitable sealing means, it being possible to dispense with additional connecting pieces, for example intermediate ducts. The use of EPDM-based seals or other sealing means simplifies assembly since there is no requirement for hose clips or the like.
- According to one embodiment, the vertically extending side wall ducts are realized between interior panelling of the rail vehicle and panelling which extends between the interior panelling of the rail vehicle and the carbody shell. The side wall ducts can thus be constructed from two half-shells and can be defined simply by the "inner" form of the pieces of panelling facing one another.
- According to one embodiment, the longitudinal ventilation duct or part or all of the hollow chamber segments have downwardly pointing exhaust air openings which open out into the passenger compartment of the rail vehicle on the bottom side of the luggage rack. In this case, the hollow chamber segments provide a direct connection to the passenger compartment by means of the exhaust air openings which are realized on the bottom side of the luggage rack. Consequently, the hollow chamber segments form, so to speak, a connecting element between the passenger compartment and the ventilation duct which extends in the ceiling region as well as an extension of the effective cross section of the ventilation duct.
- According to one embodiment, two longitudinal ventilation ducts are arranged parallel to one another in the longitudinal direction of the rail vehicle, wherein the first ventilation duct is passed through by cross ducts in which the base supports, or a top arm of the same, extend. The second ventilation duct is constructed from a first upwardly open hollow chamber and a second downwardly open hollow chamber. The first hollow chambers can comprise or can consist of individual hollow chamber segments which are connected together directly or by means of the base supports.
- The first ventilation duct can be mounted, for example, completely in the ceiling region of the rail vehicle, it extending, however, in the vertical direction as far as into the region in which the luggage rack is mounted. For example, coming from above, the first ventilation duct extends as far as over fastening elements for fastening the luggage rack on the carbody shell and covers said fastening elements. So that the luggage rack is nevertheless able to be fastened on the carbody shell, the first ventilation duct has cross ducts, through which the base supports, or parts thereof, are able to be guided in order to be moved into engagement with the fastening elements.
- The first ventilation duct is fastened on the carbody shell, but not on the luggage rack. In contrast, the second ventilation duct is supported at least in part by the luggage rack. In particular, as already described further above, the first or lower hollow chamber is formed in this case by the hollow chamber segments which are fixed on the base.
- According to one embodiment, a luggage rack module for constructing a luggage rack of a rail vehicle is provided. The luggage rack module has two base supports, which are spaced apart from one another, with fastening elements for fastening on a carbody shell of the rail vehicle, wherein the base supports have in each case at least one opening. At least one hollow chamber segment, which is open toward a top side of the luggage rack, extends between the spaced-apart base supports and is held in a sealed manner on its respective end face on the respective base support, wherein the hollow chamber segment, when viewed in the longitudinal direction, is open and surrounds the openings in the base support by way of its respective end face.
- The luggage rack module assumes several functions. On the one hand, it serves as supporting means for the luggage compartment, i.e. the base support, for example the side arms, absorb the loads occurring during normal use by the passengers and directs them into the carbody shell. Moreover, the luggage rack module enlarges the available cross section for the ventilation duct by a ceiling duct being extended by means of the hollow chamber segments as far as into the region of the luggage rack.
- The mounting of the luggage rack modules is effected, for example, along a modular dimension which is provided, for example, by the window dividers. The luggage rack modules can be pre-assembled and then fastened on site in the rail vehicle. The modular construction enables rapid assembly and, where applicable, removal and repair since it is possible to exchange individual modules.
- As an alternative to this, it is possible to assemble the individual components of the luggage rack one after the other, i.e. for example first the base supports on which the hollow chamber segments are then fastened.
- According to one embodiment, the hollow chamber segment has on its bottom side, at least one opening through which the air is able to flow into the hollow chamber segment or out of the hollow chamber segment. Along with their function of extending the cross section of the ventilation duct, the hollow chamber segments consequently also assume the function of distributing air through the openings. The openings can open out, for example, directly into the passenger compartment. In a preferred manner in this case, the openings provide exhaust air openings. As an alternative to this or in addition to it, the openings can also enable cross connection to further ducts, for example ducts along the side wall of the rail vehicle in order to conduct the air (inlet or exhaust) into or out of other regions of the passenger compartment.
- The hollow chamber segment has the function of conducting the air flow in the longitudinal direction of the rail vehicle, the air flow in this case flowing through the base supports or side arms, and distributing it in a cross direction thereto.
- According to one embodiment, the hollow chamber segment is defined on its top side by a wall with openings. The hollow chamber segment is connected by means of the openings to a top, downwardly-open hollow chamber of the ceiling duct. Together they form the ventilation duct. As an alternative to this, the hollow chamber segment can also be realized without a top wall.
- According to one embodiment, the luggage rack module has two hollow chamber segments which extend parallel to one another and are separated from one another. Consequently, it is possible to extend two ceiling ducts to construct ventilation ducts which are enlarged in cross section.
- According to one embodiment, one of the two hollow chamber segments is defined by a bottom wall which curves in part as far as below the other hollow chamber segment. The bottom wall allows one of the two ventilation ducts to be realized downwardly in the desired form, for example in order to be able to place outlet openings in a suitable manner. If the bottom wall defines, for example, an exhaust duct and if this is not arranged directly on the side wall of the rail vehicle, the curvature for example in the direction of the side wall makes it possible for the exhaust air to be able to be removed where possible from the direct vicinity of the side wall, for example above the window. This is desired for both reasons of ventilation and of convenience.
- According to one embodiment, the luggage rack module includes at least one holder for at least one of the following elements: indirect lighting, loudspeaker, seat notices. The luggage rack module consequently fulfils even more functions and can additionally also support cabling.
- According to one embodiment, the luggage rack module includes a base support module formed by the two base supports, which are spaced apart from one another and extend parallel to one another, in the form of side arms which are rigidly connected together by means of at least one longitudinal support. Consequently, a framework is constructed which supports the further components of the luggage rack module and can be fastened on the carbody shell.
- In all, the base supports together with the hollow chamber segment or segments can be realized such that they assume the following functions.
- Air conduction for hot air from the ceiling duct to the side ducts;
- Air inlet and air conduction for return air from the passenger compartment to the ceiling duct;
- Holder for luggage compartment;
- Holder for indirect lighting device;
- Holder for cover profile;
- Holder for loudspeaker;
- Holder for seat notices.
- The afore-described embodiments can be combined together in any arbitrary manner.
- The accompanying drawings illustrate embodiments and serve together with the description to explain the principles of the invention. The elements of the drawings are relative to one another and are not necessarily true to scale. Identical references designate identical parts.

Abase support 31 of aluggage rack 30 is fastened on acarbody shell 100 of the rail vehicle. Typically, theluggage rack 30 includes two base supports 31, which are spaced apart from one another, secured on thecarbody shell 100 and can also be designated as side arms. The base supports 31 absorb the loads typically occurring and direct them into thecarbody shell 100. For fastening on thecarbody shell 100 the base supports can have suitable fastening elements such as, for example, flanges or hook elements, by way of which they are fastened either directly on thecarbody shell 100 or on supporting means which are secured on thecarbody shell 100. Concrete examples are shown inFigures 4 to 8 . - In the present embodiment, the base supports 31 have two through-
openings 32 on their ends pointing to thecarbody shell 100.

Theventilation ducts luggage rack 30. In the present embodiment, the twoventilation ducts base support 31 of the luggage rack. In this embodiment, the vertical extension of the two ventilation ducts downward is approximately the same, however it can be different. - The
ventilation ducts ventilation ducts luggage rack 30 such that theventilation ducts luggage rack 30. The top region of theventilation ducts interior panelling 105 of the rail vehicle interior and thecarbody shell 100. Theinterior panelling 105 of the rail vehicle can define or delimit at least one of the twoventilation ducts - The
ventilation ducts hollow chamber hollow chamber segments luggage rack 30, and one downwardly open secondhollow chamber luggage rack 30. In order to enable an air flow in the longituidnal direction in the region of theluggage rack 30, the base supports 30 have the through-openings 32 for connection of thehollow chamber segements Figures 2 and3 which show longitudinal cross sections through the ventilation ducts.Figure 2 , in this case, corresponds to a longitudinal section which extends approximately along the downwardly pointing arrow inFigure 1 .Figure 3 , in contrast, corresponds to a longitudinal section which extends approximately along the upwardly pointing arrow inFigure 1 . - Two base supports 31, together with the
hollow chamber segments hollow chambers ventilation ducts - The top part of the
respective ventilation duct luggage rack 30 can be formed, for example, in part by ceiling panelling elements or shell elements. These can be formed integrally together with the ceiling panelling, which is part of the panelling of therail vehicle 105, or can comprise or can consist of individual elements connected together. Together they form the secondhollow chambers - In contrast, the bottom part of the
respective ventilation ducts luggage rack 30 which points to thecarbody shell 100 and is formed there by the individualhollow chamber segments hollow chamber segments hollow chamber hollow chamber segments - An air flow into the first
hollow chambers openings 32 in the base supports 31, in this case a large through-opening 32 being associated in each case with a firsthollow chamber base support 31 is to be increased, it is possible to adapt the cross section of theopenings 32 in a corresponding manner or to provide several smaller openings. The overall cross section of the through-openings, however, should ideally then be adapted in such a manner that a good longitudinal airflow is made possible. - The first
hollow chambers hollow chambers respective ventilation ducts ventilation duct - By extending the
ventilation ducts luggage rack 30, the cross section of therespective ventilation ducts - In this case, the
first ventilation duct 10, which is adjacent thecarbody shell 100 in the embodiment shown inFigures 1 and 2 , provides a hot air duct. Said hot air duct is connected on its bottom side toside wall ducts 40 which extend laterally next towindows 110 and by means of which the hot inlet air can be directed into the bottom region of the passenger compartment, for example into the floor region. To this end, thefirst ventilation duct 10 or thehollow chamber segments 11a has/have downwardlyopen openings 14 which make connection to the vertically extendingside wall ducts 40 possible. This is shown in a more precise manner inFigure 5 . Suitable sealing materials, for example based on EPDM, can be used for sealing between thefirst ventilation duct 10 and the side wall ducts. - Compared to this, the
second ventilation duct 20, which is adjacent the passenger compartment in the embodiments shown inFigures 1 and3 , provides an exhaust air duct which is connected to the interior of the passenger compartment by means ofexhaust air openings 24. Theexhaust air openings 24, in this case, can be arranged on the bottom side of theluggage rack 30. - The individual
hollow chamber segments hollow chambers hollow chambers - According to the embodiment presented here, the first
hollow chambers hollow chambers -
Figures 4 and5 show concrete embodiments of a ventilation duct. The base supports 31 are suspended in asupport plate 113 and fastened on the same. Thesupport plate 113 is fastened on two C-rails 111, which are realized for example integrally with thecarbody shell 100, with dampingelements 112. - The
first ventilation duct 10 forms a hot air duct which is designated inFigure 4 by the reference WL. The firsthollow chamber 11 of the hot air duct is defined byside walls 15, atop wall 17 and abottom wall 16 which extend between the base supports 31. Thesecond ventilation duct 20 forms a return air duct which is designated inFigure 4 by the reference RL. The firsthollow chamber 21 of thesecond ventilation duct 20 is defined byside walls 25, atop wall 27 and abottom wall 26. Theside wall hollow chambers - The
bottom wall 16 of the firsthollow chamber 11 of thefirst ventilation duct 10 hasopenings 14 for connection to theside wall ducts 40. As shown inFigure 4 , aflexible duct 41 can produce the connection to theside wall duct 40 and balances out possible tolerances. In addition, better vibration decoupling and sealing is achieved in this manner. - Connecting
openings 18 are provided in thetop wall 17 of the firsthollow chamber 11 of thefirst ventilation duct 10. Said connecting openings extend the firsthollow chamber 11 upward into the secondhollow chamber 12. - The
bottom wall 26 of the firsthollow chamber 21 of thesecond ventilation duct 20 is formed by a profile element produced from thin material which extends in part below thebase support 31. On its side pointing to the passenger compartment, thebottom wall 26 engages in a receiving means 25a of theside wall 25 pointing to the passenger compartment and is held there in sealed manner. Thebottom wall 26 hasexhaust air openings 24 in the form of slits. Their downwardly curved form in the direction of theside wall 100 of the rail vehicle makes it possible to realize the exhaust air openings in such a manner that they point away from the passenger compartment toward the side wall of the rail vehicle. As a result, theexhaust air openings 24 are not visible, which is preferred for aesthetic reasons. On the other hand, the return air is removed directly above the window such that a preferred return flow along the window is achieved. - As can be seen in particular in
Figure 5 , thesecond ventilation duct 20 extends in part below thefirst ventilation duct 10 as a result of the outwardly curvedbottom wall 26. Thebottom wall 26 can additionally receive lighting devices which enable indirect lighting. To this end, thebottom wall 26 can be formed in a part region such that it forms anindentation 26a which extends in the longitudinal direction. A, for example,transparent cover 45 closes theindentation 26a in which lighting means (not shown here) are able to be accommodated. - Moreover, by means of corresponding forming, the
bottom wall 26 can also provide the possibility for accommodating loudspeakers, sensors and cabling. In all, thebottom wall 26 covers, in a visual and functional manner, the region of theluggage rack 30 pointing to thecarbody shell 100 and serves as a profile above the window. - The
top wall 27 of the firsthollow chamber 21 of thesecond ventilation duct 20 also has connecting openings in order to connect thehollow chambers second ventilation duct 20. Thetop walls - First
hollow chamber segments openings 32 in the base supports 31. Theside walls top walls bottom walls - The
luggage rack 30 can also have aluggage compartment 36 on its bottom side. - As can be seen from
Figure 9 , the vertically extendingside wall ducts 40 can be realized betweeninterior panelling 121 of the rail vehicle andpanelling 122 which extends between theinterior panelling 121 of the rail vehicle and thecarbody shell 100. Thepanelling side wall ducts 40 and are connected together in a suitable manner. The hot air or inlet air conducted through theside wall ducts 40 into the floor region passes, for example, into the passenger compartment at theopenings 123 which are realized, for example, in theinterior panelling 121 of the rail vehicle. - The
individual panelling carbody shell 100 or on support elements secured on said carbody shell for example by means of individual hinges or other means such that, in particular, theinterior panelling 121 of the rail vehicle, or parts thereof, are able to be hinged up, for example, for the purpose of inspection. - The second
hollow chambers luggage rack 30 can comprise or can consist of individual segments which are joined to one another in the longitudinal direction. If, for example, as shown inFigure 4 , further ventilation ducts are provided as well as the hot air duct WL (first ventilation duct) and the return air duct RL (second ventilation duct), the individual segments can have a structure for the construction of said ventilation ducts and at the same time form part of the interior panelling of the rail vehicle in the region of the ceiling. InFigure 4 , an exhaust air duct AL extends above the hot air duct WL and the return air duct RL. A ventilation duct CL which is provided for cooling can be realized laterally of and above the return air duct RL. The individual segments can be pre-assembled in a suitable manner for this purpose i.e. each segment, in the case ofFigure 4 , has four cavities or hollows, the cavities being downwardly open for the return air duct RL and for the hot air duct WL and provide each of the second hollow chambers of said ventilation ducts. The two other ventilation ducts AL and CL, in contrast, are closed when viewed in cross section. Adjacent ventilation ducts can be separated from one another by means of common intermediate walls. - The individual segments can have, as an integral unit, the outside and partition walls necessary for construction of the ventilation ducts. As an alternative to this, it is possible to construct the individual segments from individual flat elements or from a combination of part-formed flat elements.
-
Figures 6 to 8 show a further embodiment of the ventilation ducts by lengthening the same into the region of the luggage rack. Thefirst ventilation duct 210, which serves once again in this case as a hot air duct, is realized in the embodiment shown as a continuous unit when viewed in cross section, i.e. a hollow chamber formed by hollow chamber segments is not present. In contrast, thesecond ventilation duct 220 is constructed substantially as inFigures 4 and5 . - Part of the
first ventilation duct 210 extends "behind" the firsthollow chamber 221 of thesecond ventilation duct 220, i.e. into the region between the firsthollow chamber 221 and thecarbody shell 100.Cross ducts 250 pas through thefirst ventilation duct 210 in this region. Thecross ducts 250 are provided at the places at which thebase support 231 crosses thefirst ventilation duct 210 such that said base support passes through thecross ducts 250 and engages in thecarbody shell 100 and asupport plate 213. Thecross ducts 250 are sealed in relation to thefirst ventilation duct 210. - The base supports 231 are modified slightly for this purpose in comparison to
Figures 4 and5 . The base supports 231 have two free arms on their ends pointing to thecarbody shell 100. Specifically, they have onetop arm 233 with hooks and onebottom arm 234 with a flange for support on thesupport plate 213. Thetop arm 233, and consequently thebase support 231, is suspended from thesupport plate 213 by means of the hook. - This is clearly shown in
Figures 7 and8 , which show cross sections through theluggage rack 230 and the ventilation device,Figure 7 showing a cross section between two base supports 231 of a luggage rack module andFigure 8 showing a cross section along abase support 231, which is realized in this case in the form of a side arm. - Moreover, two base supports 231 of a luggage rack module are connected together rigidly by means of
longitudinal supports 236 in order to form a base support module from base supports 231 andlongitudinal supports 236. As a result, the stability of theluggage rack 230 is improved. Such a solution withlongitudinal supports 236 is also possible in the case of the other embodiments described here and is preferred in particular wherever sufficient stability is desired. In addition, it is easier to assemble a luggage rack module with such a base support module as it is more torsionally rigid. - The luggage rack module in
Figures 6 to 8 consequently includes abase support module hollow chamber segment 221a for construction of the firsthollow chamber 221 of thesecond ventilation duct 220. During assembly, thefirst ventilation duct 210 is mounted first of all in the region of the ceiling. In this case, care must be taken to ensure that thecross ducts 250 are aligned with thesupport plates 213. In addition, as already explained in conjunction with the other embodiments, the second or top hollow chamber (not shown inFigure 6 to 8 ) is mounted on the ceiling. - A luggage rack module is then fastened by the two
top arms 233 of the luggage rack module being moved throughrespective cross ducts 250 and engaging behind thesupport plate 213 by way of their hooks. The luggage rack module is supported against thesupport plate 213 by means of the flanges of the bottom arms and can also be fastened there, for example by means of screws. - By mounting several luggage rack modules, the first
hollow chamber 221 of the second ventilation duct is achieved by joining thehollow chamber segments 221a in the longitudinal direction by means of adjoining base supports 231 of adjacent luggage rack modules. The first or bottomhollow chamber 221 of the second ventilation duct then forms thesecond ventilation duct 220 with the second or tophollow chamber 222, the twohollow chambers openings 228 in thetop wall 227 of the firsthollow chamber 221 and connectingopenings 228a in the bottom wall of the secondhollow chamber 222. - In contrast to the embodiment in
Figures 4 and5 , the firsthollow chamber 221 has aninner wall 229 withopenings 229a. This is optional and serves to stabilize the firsthollow chamber 221. Abottom wall 226 of thesecond ventilation duct 220, as already described further above, is formed by a cover to the passenger compartment which hasexhaust air openings 224. - The
hollow chamber segments 221a of the firsthollow chamber 221 additionally have a receiving means 260 for ceiling panels which at the same can seal the second ventilation duct against the interior of the passenger compartment. Other seals between the first and secondhollow chamber first ventilation duct 210 is realized in an integral manner. -
Figure 8 does not show thehollow chamber segments 221 a as they do not extend through the base supports 231, but end by way of their end faces at said base supports and can be suitably sealed. The longitudinal connection between thehollow chamber segments 221a for construction of the first hollow chamber is effected by means of the through-openings 232. - The above-described embodiments can be combined in an arbitrary manner, provided they fall under the scope of the appended claims.
- Although specific embodiments have been shown and described herein, it is within the framework of the present invention to modify the embodiments shown in a suitable manner without deviating from the scope of protection of the present invention. as described in the appended claims.
