Definitions

  • the invention relates to a railway wagon with heating or air conditioning, an air duct running below the lower edge of the compartment windows arranged in the wagon outer wall, from which supply ducts extend to outlet openings at the height of the lower window edges on the one hand and above the upper window edges on the other hand

  • Such an arrangement is known, for example, from AT-B 355618 and, due to the outflow of the heated or air-conditioned air at the lower window edge on the one hand and above the upper window edge on the other hand, enables very uniform and draft-free heating or air conditioning of the wagon compartment.
  • the disadvantage here is that the installation of the intermediate wall delimiting the supply ducts to the inside of the wagon is relatively complex, since for a sufficient seal against the inside of the outside of the wagon or against the window edges as well as for maintaining the required distance from this inside to ensure the necessary Cross sections for the air flow must be provided.
  • the object of the present invention is to achieve an improvement of the known arrangement, while maintaining the advantages of the known arrangement with regard to the distribution of the inflowing air into the compartment, in such a way that in particular the assembly of the entire arrangement is simplified and a low-noise, optically simple means attractive, closed construction is achieved in particular with regard to the air duct.
  • the intermediate wall is designed as a compartment-side boundary of a hollow frame which contains the supply channels and is connected to transfer openings of the air guide channel.

Description

Die Erfindung betrifft einen Eisenbahnwaggon mit Heiz- bzw. Klimaanlage, wobei unterhalb des unteren Randes der in der Waggonaussenwand angeordneten Fenster der Abteile ein Luftführungskanal verläuft, von dem ausgehend Zuleitungskanäle bis zu Ausströmöffnungen in der Höhe der unteren Fensterränder einerseits und oberhalb der oberen Fensterränder andererseits verlaufen, welche Zuleitungskanäle zur Waggoninnenseite hin von einer auch zur Abdeckung von Fensterrändern dienenden zumindest einen Teil des senkrechten Bereichs der Innenseite der Waggonaussenwand oberhalb des Luftführungskanals überdeckenden Zwischenwand begrenzt sind.The invention relates to a railway wagon with heating or air conditioning, an air duct running below the lower edge of the compartment windows arranged in the wagon outer wall, from which supply ducts extend to outlet openings at the height of the lower window edges on the one hand and above the upper window edges on the other hand Which supply ducts are delimited to the inside of the wagon by an intermediate wall which also covers at least part of the vertical region of the inside of the outside of the wagon above the air duct and also serves to cover window edges.

Eine derartige Anordnung ist beispielsweise aus der AT-B 355618 bekannt, und ermöglicht zufolge der Ausströmung der erwärmten bzw. klimatisierten Luft am unteren Fensterrand einerseits und oberhalb des oberen Fensterrandes andererseits eine sehr gleichmässige und zugfreie Beheizung bzw. Klimatisierung des Waggonabteils. Nachteilig ist dabei allenfalls, dass die Montage der die Zuleitungskanäle zur Waggoninnenseite hin begrenzenden Zwischenwand relativ aufwendig ist, da für eine ausreichende Abdichtung gegen die Innenseite der Waggonaussenwand bzw. gegen die Fensterränder sowie auch für die Einhaltung des erforderlichen Abstandes zu dieser Innenseite zur Sicherstellung der notwendigen Querschnitte für die Luftführung gesorgt werden muss.Such an arrangement is known, for example, from AT-B 355618 and, due to the outflow of the heated or air-conditioned air at the lower window edge on the one hand and above the upper window edge on the other hand, enables very uniform and draft-free heating or air conditioning of the wagon compartment. The disadvantage here is that the installation of the intermediate wall delimiting the supply ducts to the inside of the wagon is relatively complex, since for a sufficient seal against the inside of the outside of the wagon or against the window edges as well as for maintaining the required distance from this inside to ensure the necessary Cross sections for the air flow must be provided.

Aufgabe der vorliegenden Erfindung ist es, unter Beibehaltung der genannten Vorteile der bekannten Anordnung hinsichtlich der Verteilung der einströmenden Luft in das Abteil eine Verbesserung der genannten bekannten Anordnung dahingehend zu erreichen, dass insbesonders die Montage der gesamten Anordnung vereinfacht und mit einfachen Mitteln eine geräuscharme, optisch ansprechende, geschlossene Konstruktion insbesonders im Hinblick auf die Luftführungskanäle erreicht wird.The object of the present invention is to achieve an improvement of the known arrangement, while maintaining the advantages of the known arrangement with regard to the distribution of the inflowing air into the compartment, in such a way that in particular the assembly of the entire arrangement is simplified and a low-noise, optically simple means attractive, closed construction is achieved in particular with regard to the air duct.

Dies wird gemäss der Erfindung dadurch erreicht, dass die Zwischenwand als abteilseitige Begrenzung eines hohlen Rahmens ausgebildet ist, der die Zuleitungskanäle enthält und mit Überleitungsöffnungen des Luftführungskanals in Verbindung steht. Die Zuleitungskanäle zu den Ausströmöffnungen sind also unabhängig von der Innenseite der Waggonaussenwand in dem hohlen Rahmen ausgebildet, womit dieser bei der Montage des Eisenbahnwaggons nur mehr auf sehr einfache Weise an dieser Innenseite befestigt werden muss; dabei sind keinerlei Anforderungen hinsichtlich der Abdichtung bzw. der Einhaltung eines genauen Abstandes mehr zu erfüllen, was - bei gleichzeitiger Sicherstellung der optimalen Funktion - die Montagearbeit sehr vereinfacht.This is achieved according to the invention in that the intermediate wall is designed as a compartment-side boundary of a hollow frame which contains the supply channels and is connected to transfer openings of the air guide channel. The supply ducts to the outflow openings are thus formed in the hollow frame independently of the inside of the wagon outer wall, so that this only has to be attached to this inside in a very simple manner when the railway wagons are assembled; there are no more requirements with regard to sealing or maintaining a precise distance, which - while ensuring the optimal function - simplifies assembly work.

Gemäss einer Ausgestaltung der Erfindung sind im Inneren des hohlen Rahmens Luftführungseinrichtungen zur strömungsmässigen Separierung der Zuleitungskanäle angeordnet. Diese Luftführungseinrichtungen können also bereits vor der Montage des hohlen Rahmens im Eisenbahnwaggon in diesem Rahmen beispielsweise bereits im Zuge von dessen Herstellung vorgesehen werden, was die Montagearbeiten im Eisenbahnwaggon nicht weiter belastet.According to one embodiment of the invention, air guiding devices for the flow separation of the supply channels are arranged in the interior of the hollow frame. These air guiding devices can therefore already be provided in this frame, for example in the course of its manufacture, even before the hollow frame is installed in the railway wagon, which does not further burden the assembly work in the railway wagon.

Gemäss einer vorteilhaften Ausgestaltung kann in diesem Zusammenhang auch vorgesehen sein, dass die Luftführungseinrichtungen verstellbare, z.B. von der Regelung der Heiz- bzw. Klimaanlage beeinflussbare, Steuereinrichtungen, insbesondere Klappen aufweisen, die die freien Durchströmungsquerschnitte der Zuleitungskanäle im hohlen Rahmen kontrollieren. Diese Klappen können beispielsweise so ausgebildet sein, dass sie nach der Montage des Rahmens im Eisenbahnwaggon einmal im Hinblick auf optimale Ausströmbedingungen aus den verschiedenen Ausströmöffnungen eingestellt werden und im Betrieb der Heiz- bzw. Klimaanlage nicht mehr verstellt werden. Vorteilhaft wäre auch, eine Verstellung dieser Steuereinrichtungen durch die Regelung der Heiz- bzw. Klimaanlage vorzusehen. So könnten beispielsweise die am unteren Fensterrand angeordneten Ausströmöffnungen, die hauptsächlich im Heizbetrieb ein Beschlagen der Fenster verhindern sollen, durch Abschliessen der zugehörigen Zuleitungskanäle im Kühlbetrieb geschlossen werden.According to an advantageous embodiment, it can also be provided in this connection that the air guiding devices are adjustable, e.g. have control devices, in particular flaps, which can be influenced by the regulation of the heating or air conditioning system and which control the free flow cross sections of the supply channels in the hollow frame. These flaps can be designed, for example, so that once the frame has been installed in the railroad car, they are adjusted once with a view to optimal outflow conditions from the various outflow openings and are no longer adjusted during operation of the heating or air conditioning system. It would also be advantageous to provide an adjustment of these control devices by regulating the heating or air conditioning system. For example, the outflow openings arranged at the lower edge of the window, which are primarily intended to prevent the windows from fogging up in heating mode, could be closed by closing off the associated supply ducts in cooling mode.

Besonders vorteilhaft ist es, wenn der hohle Rahmen einteilig ausgeführt und an der Innenseite der Waggonaussenwand anbringbar ist, da damit die Montagearbeit lediglich auf Einrichten und Befestigen eines einzigen Bauteils an der Innenseite der Waggonaussenwand beschränkt ist.It is particularly advantageous if the hollow frame is made in one piece and can be attached to the inside of the wagon outer wall, since the assembly work is thus limited to setting up and fastening a single component on the inside of the wagon outer wall.

Der Rahmen kann gemäss einer Ausgestaltung der Erfindung als Kunststoffspritzteil ausgeführt sein, was einerseits eine kostengünstige Herstellung ermöglicht und andererseits auch Vorteile im Zusammenhang mit der Wärmeisolierung und Schalldämmung bringt.According to one embodiment of the invention, the frame can be designed as a plastic injection-molded part, which on the one hand enables cost-effective production and on the other hand also brings advantages in connection with thermal insulation and sound insulation.

Zur weiteren Vereinfachung der Montage des Eisenbahnwaggons ist vorgesehen, dass der hohle Rahmen mittels einer Dichtung gegenüber der Waggonaussenwand abgedichtet ist, die auch zur Halterung und Abdichtung des Fensters dient. Dabei muss lediglich der das vormontierte Fenster enthaltende Rahmen als vormontierter Bauteil bei der Endmontage des Waggons an entsprechender Stelle der Innenseite der Aussenwand angebracht, verbunden und abgedichtet werden.To further simplify the assembly of the railway wagon, it is provided that the hollow frame is sealed off from the outside of the wagon by means of a seal which also serves to hold and seal the window. All that needs to be done is to attach, connect and seal the frame containing the preassembled window as a preassembled component during the final assembly of the wagon at a corresponding point on the inside of the outer wall.

Gemäss einer anderen Ausgestaltung der Erfindung kann vorgesehen sein, dass der hohle Rahmen aus mehreren Teilen besteht, weiche je für sich einen separaten, zu einer Ausströmöffnung bzw. einer Gruppe von Ausströmöffnungen führenden Zuleitungskanal bilden. Auf diese Weise können beispielsweise für jede der vorgesehenen Ausströmöffnungen eigene jeweils aneinander anschliessende Rahmenteile vorgesehen sein, deren Herstellung gegenüber einem einzigen, die ganze Abteilwand bedeckenden Bauteil vereinfacht ist und die trotzdem vom Abteil aus gesehen eine einzige, praktisch durchgehende Zwischenwand zur Abteilinnenseite hin bilden.According to another embodiment of the invention, it can be provided that the hollow frame consists of several parts, each of which forms a separate feed channel leading to an outflow opening or a group of outflow openings. In this way it is possible, for example, for each of the outflow openings provided to have its own adjoining frame parts, the manufacture of which is simplified compared to a single component which covers the entire compartment wall, and which is nevertheless from the compartment seen form a single, practically continuous partition wall to the inside of the compartment.

Eine weitere Ausgestaltung der Erfindung sieht vor, dass der hohle Rahmen zusammen mit zumindest einem Teil des im Abteil verlaufenden Luftführungskanals eine vormontierbare Baueinheit bildet. Damit ist auf sehr einfache Weise die Montage der in jedem Abteil vorhandenen Teile der Luftführung erleichtert, da der eigentliche Luftführungskanal mit dem die Zuleitungskanäle enthaltenden hohlen Rahmen vormontierbar ist und somit bei der eigentlichen Montage im Abteil nur noch die Anschlüsse zu den sonstigen Teilen der Luftführung der Heiz- bzw. Klimaanlage hergestellt werden müssen.A further embodiment of the invention provides that the hollow frame forms a preassembled structural unit together with at least part of the air duct running in the compartment. This simplifies the assembly of the parts of the air duct in each compartment in a very simple manner, since the actual air duct can be preassembled with the hollow frame containing the inlet ducts and thus only the connections to the other parts of the air duct during the actual assembly in the compartment Heating or air conditioning must be manufactured.

In einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die Baueinheit im Bereich des Luftführungskanals an beiden Seiten Anschlussteile aufweist, die im eingebauten Zustand im Abteil gegen dort vorgesehene Anschlussöffnungen abdichten. Im Bereich der zusammenwirkenden Anschlussöffnungen bzw. -teile können bedarfsweise Dichtungen, Befestigungseinrichtungen (wie Schrauben, Befestigungswinkel od. dgl.) oder sonstige die Montage ermöglichende und eine sichere Abdichtung bewirkende Zusatzteile angebracht werden. Schliesslich ist gemäss einer besonders vorteilhaften Ausgestaltung der Erfindung vorgesehen, dass die Baueinheit als einstückiger Kunststoffspritzteil ausgebildet ist. Dadurch ist die Vormontage überflüssig und infolge der Leichtheit, sowie auch der wärmeisolierenden Eigenschaften von Kunststoff sind weitere Vorteile gegeben.In an advantageous embodiment of the invention, it is provided that the structural unit in the area of the air duct has connection parts on both sides which, in the installed state, seal in the compartment against connection openings provided there. In the area of the cooperating connection openings or parts, if necessary, seals, fastening devices (such as screws, fastening brackets or the like) or other additional parts which enable assembly and provide a secure seal can be attached. Finally, according to a particularly advantageous embodiment of the invention, it is provided that the structural unit is designed as a one-piece plastic injection-molded part. This eliminates the need for pre-assembly, and due to the lightness and the heat-insulating properties of plastic, there are further advantages.

Das in Fig. ersichtliche Abteil 1 eines nicht weiter dargestellten Eisenbahnwaggons ist über einen Luftführungskanal 2 mit einer ebenfalls nicht weiter dargestellten Heiz- bzw. Klimaanlage verbunden, welche üblicherweise beispielsweise unterhalb des Waggonbodens angeordnet ist und erwärmte bzw. klimatisierte Luft dem Abteil 1 zuführt.The compartment 1 shown in FIG. 1 of a railway wagon, not shown, is connected via an air duct 2 to a heating or air conditioning system, also not shown, which is usually arranged, for example, below the wagon floor and supplies heated or conditioned air to the compartment 1.

Der Luftführungskanal 2 ist dabei unterhalb des unteren Randes 3 eines in der Waggonaussenwand 4 eingelassenen Fenster 5 entlang der fensterseitigen Abteilwand durchgehend angeordnet, und ist überZuleitungskanäle 6, 7, 8 mit Ausströmöffnungen 9, 10 in der Höhe des unteren Fensterrandes 3 einerseits und oberhalb des oberen Fensterrandes 11 andererseits verbunden.The air duct 2 is arranged below the lower edge 3 of a window 5 embedded in the outer wall 4 of the wagon along the window-side compartment wall, and is via supply ducts 6, 7, 8 with outflow openings 9, 10 at the height of the lower window edge 3 on the one hand and above the upper one Window edge 11 connected on the other hand.

Die Zuleitungskanäle 6, 7, 8 sind zur Waggoninnenseite hin von einer auch zur Abdeckung der Fensterränder 3, 11, 12, 13 dienenden, zumindest einen Teil des senkrechten Bereiches der Innenseite der Waggonaussenwand 4 oberhalb des Luftführungskanals 2 überdeckenden Zwischenwand 14 begrenzt, welche als abteilseitige Begrenzung eines hohlen Rahmens 15 ausgebildet ist, der die Zuleitungskanäle 6, 7, 8 aufnimmt und mit Überleitungsöffnungen 16 (Fig.2) des Luftführungskanals 2 in Verbindung steht. Dieser hohle Rahmen weist Luftführungseinrichtungen 17 zur strömungsmässigen Separierung der Zuleitungskanäle 6, 7, 8 auf, wobei über verstellbare Klappen 18 oder ähnliche Steuereinrichtungen die freien Durchströmquerschnitte kontrolliert und beispielsweise in Abhängigkeit von der Regelung der Heiz- bzw. Klimaanlage verstellt werden können.The supply ducts 6, 7, 8 are delimited to the inside of the wagon by an intermediate wall 14 which also serves to cover the window edges 3, 11, 12, 13 and covers at least part of the vertical area of the inside of the wagon outer wall 4 above the air duct 2, which serves as a compartment Boundary of a hollow frame 15 is formed, which receives the supply channels 6, 7, 8 and is connected to transfer openings 16 (Fig.2) of the air duct 2. This hollow frame has air guiding devices 17 for the flow separation of the supply ducts 6, 7, 8, the free flow cross sections being able to be controlled via adjustable flaps 18 or similar control devices and being adjusted, for example, depending on the regulation of the heating or air conditioning system.

Bei einer anderen Ausführungsform, dargestellt in Fig. 1a, bei der für gleiche Teile gleiche Bezugszeichen Verwendung finden, sind die Zuleitungskanäle 6', 7', 8' ebenfalls zur Waggoninnenseite hin von einer auch zur Abdeckung der Fensterränder dienenden, zumindest einen Teil des senkrechten Bereiches der Innenseite der Waggonaussenwand 4 oberhalb des Luftführungskanals 2 überdeckenden Zwischenwand 14 begrenzt, welche als abteilseitige Begrenzung eines hohlen Rahmens 15 ausgebildet ist, der mit dem Luftführungskanal eine vormontierbare Baueinheit 32 bildet. Der hohle Rahmen 15 kann auch Luftführungseinrichtungen 17' zur strömungsmässigen Separierung der Zuleitungskanäle 6', 7', 8' aufweisen, wobei auch verstellbare Klappen 18' oder ähnliche Steuereinrichtungen vorgesehen sind. Gemäss der in Fig. la dargestellten Ausführungsform ist die Baueinheit 32 einstückig, beispielsweise als Kunststoffspritzteil ausgeführt und weist auch unmittelbar die Ausströmöffnungen 9 an der Fensterunterkante und hier nicht dargestellt, jene an der Fensteroberkante und den seitlichen Fensterrändern auf.In another embodiment, shown in Fig. 1a, in which the same reference numerals are used for the same parts, the feed channels 6 ', 7', 8 'are also towards the inside of the wagon from at least part of the vertical also serving to cover the window edges Limited area of the inside of the outer wall 4 of the wagon above the intermediate wall 14 covering the air duct 2, which is designed as a compartment-side boundary of a hollow frame 15 which forms a preassembled unit 32 with the air duct. The hollow frame 15 can also have air guiding devices 17 'for the flow separation of the supply ducts 6 ' , 7 ', 8 ' , adjustable flaps 18 'or similar control devices also being provided. According to the embodiment shown in FIG. 1 a, the structural unit 32 is in one piece, for example as a plastic injection-molded part, and also has the outflow openings 9 on the lower window edge and not shown here, those on the upper window edge and the lateral window edges.

Bei einer Teilung der Baueinheit 32 in hohlen Rahmen 15 und Luftführungskanal 2, ist es auch möglich, die einzelnen Bestandteile aus jeweils geeigneten Materialien anzufertigen, beispielsweise Blech einerseits und Kunststoff andererseits.If the structural unit 32 is divided into a hollow frame 15 and air duct 2, it is also possible to manufacture the individual components from suitable materials, for example sheet metal on the one hand and plastic on the other hand.

In der Darstellung nach Fig. 1a ist auch zu erkennen, dass die Baueinheit 32 im Bereich des Luftführungskanals 2 an beiden Seiten Anschlussteile 33 aufweist, die in eingebautem Zustand der Baueinheit im Abteil 1 gegen dort - beispielsweise in Form von Stutzen od. dgl. - vorgesehene Anschlussöffnungen 34 abdichten. Bei der Montage allenfalls vorzusehende Dichtungen, Befestigungsteile, usw. sind nicht dargestellt.In the illustration according to FIG. 1a it can also be seen that the assembly 32 in the area of the air duct 2 has connection parts 33 on both sides, which in the installed state of the assembly in compartment 1 against it - for example in the form of connecting pieces or the like. Seal the intended connection openings 34. Any seals, fasteners, etc. to be provided during assembly are not shown.

Der hohle Rahmen 15 bzw. die Baueinheit 32 sind einstückig, beispielsweise als Kunststoffspritzteile ausgeführt, und weisen auch unmittelbar die Ausströmöffnungen 9 (Fensterunterkante) und 10 (Fensteroberkante) auf. Es ist auch möglich, den Rahmen als Blechpressteil auszubilden und zumindest an der Abteilinnenseite mit einer vorzugsweise geräusch- bzw. wärmedämmenden Beschichtung zu versehen. Zusätzlich dazu könnten in beiden Fällen auch im Bereich der seitlichen Fensterränder 12, 13 Ausströmöffnungen vorgesehen sein, die jeweils zum gegenüberliegenden Fensterrand ausgerichtet wären, da infolge des zur Verfügung stehenden relativ grossen Querschnittes der Zuleitungskanäle nur geringe Strömungsgeschwindigkeiten vorgesehen werden müssen und somit keine Belästigung der jeweils am Fensterplatz gegenüber sitzenden Reisenden zu befürchten ist. Für diese Ausströmöffnungen könnten auch gegebenenfalls zusätzliche Luftführungseinrichtungen bzw. Steuereinrichtungen vorgesehen sein.The hollow frame 15 or the structural unit 32 are made in one piece, for example as injection-molded plastic parts, and also have the outflow openings 9 (lower window edge) and 10 (upper window edge). It is also possible to design the frame as a pressed sheet metal part and to provide it with a preferably noise or heat-insulating coating at least on the inside of the compartment. In addition to this, in both cases, outflow openings could also be provided in the area of the lateral window edges 12, 13, each of which would be aligned with the opposite window edge, since, owing to the relatively large cross-section of the supply ducts available, only low flow velocities have to be provided and therefore no annoyance to the respective ones at the window seat opposite to seated travelers is to be feared. Additional air guidance devices or control devices could also be provided for these outflow openings, if necessary.

Wie insbesonders aus Fig.2 ersichtlich ist, kann der hohle Rahmen 15 im Bereich des Zuleitungskanals 7 zur Ausströmöffnung 9 an der Fensterunterkante 3 eine Einlassöffnung 19 zur Zufuhr von Abteilumluft aufweisen. Durch die Anordnung dieser Einlassöffnungen 19 wird die Ausbildung des hohlen Rahmens 15 nicht wesentlich komplizierter und kann auch die im Abteil vorhandene Warmluft zur Beschlagfreihaltung des Fensters 5 herangezogen werden. Dabei kann es von Vorteil sein, wenn im Bereich der Einlassöffnung 19 ein zusätzlicher Heizkörper im Rahmen angeordnet ist, der zur Aufwärmung der dem Fenster 5 zuzuführenden Mischluft dient.As can be seen in particular from FIG. 2, the hollow frame 15 can have an inlet opening 19 for the supply of compartment air in the area of the supply duct 7 to the outflow opening 9 at the lower window edge 3. The arrangement of these inlet openings 19 does not make the formation of the hollow frame 15 much more complicated and the warm air present in the compartment can also be used to keep the window 5 free of fogging. It can be advantageous if an additional heating element is arranged in the frame in the area of the inlet opening 19 and is used to heat the mixed air to be supplied to the window 5.

Durch diese Ausbildung der Zuleitungskanäle zu den Ausströmöffnungen der Heiz- bzw. Klimaanlage in dem gleichzeitig grosse Teile der Innenseite der Waggonaussenwand bedeckenden hohlen Rahmen bzw. der Baueinheit 32, ist insbesonders eine grosse Erleichterung der Montage gegeben, da einerseits die aufwendige Abdichtung der Zuleitungskanäle und andererseits die Justierung eines definierten Abstandes der Zwischenwand 14 zur Innenseite der Waggonaussenwand wegfällt und nur noch ein kompletter Teil an der Innenseite der Fensterwand montiert zu werden braucht. In diesem Zusammenhang wäre es zur Erleichterung der Herstellung bzw. Montage aber auch möglich, den hohlen Rahmen beispielsweise entlang der Luftführungseinrichtungen 17' und des dann bis zu den oberen Ausströmöffnungen anschliessenden Fensterrandes zu teilen, wobei nach der Montage aber nach wie vor eine zumindest weitgehend geschlossene einheitliche Abteilinnenwand gegeben wäre.This design of the supply ducts to the outflow openings of the heating or air conditioning system in the hollow frame or the structural unit 32, which at the same time covers large parts of the inside of the wagon outer wall, makes assembly much easier, since on the one hand the complex sealing of the supply ducts and on the other hand the adjustment of a defined distance of the intermediate wall 14 to the inside of the outside of the wagon is eliminated and only a complete part needs to be installed on the inside of the window wall. In this context, it would also be possible to facilitate the manufacture or assembly, for example, to divide the hollow frame along the air guiding devices 17 ' and the window edge which then adjoins up to the upper outflow openings, but after the assembly still an at least largely closed one uniform compartment inner wall would be given.

Der Vollständigkeit halber ist noch darauf hinzuweisen, dass in Fig.1 bzw. Fig. 1a mit 20 eine Deckenleuchte, mit 21 die Gepäckträger, mit 22 die Sitze, mit 23 die Abstelltischchen, mit 24 ein Abfallbehälter und mit 25 und 26 die Abteilseitenwände bezeichnet sind.For the sake of completeness, it should also be pointed out that in FIG. 1 and FIG. 1a, 20 denotes a ceiling light, 21 the luggage rack, 22 the seats, 23 the storage tables, 24 a waste container and 25 and 26 the compartment side walls are.

In der Schnittdarstellung der Fig. 4 ist ersichtlich, dass der Querschnitt des hohlen Rahmens und damit des Zuleitungskanals 6 relativ gross gewählt werden kann, so dass sich niedere Durchströmgeschwindigkeiten ergeben, was sich insbesonders auch in einer sehr niederen Geräuschentwicklung bemerkbar macht. Soferne in diesem Bereich - wie erwähnt - seitliche Ausströmöffnungen vorgesehen werden, ist eine Belästigung von am Fensterplatz gegenübersitzenden Reisenden durch direkte Zugwirkung ausgeschlossen.4 shows that the cross section of the hollow frame and thus of the feed channel 6 can be chosen to be relatively large, so that low flow rates result, which is particularly noticeable in a very low noise level. If, as mentioned, lateral outflow openings are provided in this area, annoyance to passengers sitting opposite at the window seat by direct train action is excluded.

Im Detail der Fig.5 ist schliesslich noch eine Möglichkeit dargestellt, die Zuleitungskanäle 6 bzw. 8 im Bereich der Oberkante 27 des hohlen Rahmens 15 in eine Überströmöffnung 28 münden zu lassen, welche die zugeführte Luft hinter die Innenhaut 29 des gewölbten Waggondaches 30 führt, von wo sie über Ausströmöffnungen 31 austreten kann. Auf diese Weise kann unter Umständen eine weitere Verbesserung der Verteilung der geheizten bzw. klimatisierten Luft im Abteil erreicht werden.Finally, in detail in FIG. 5 a possibility is shown of having the supply channels 6 and 8 open into an overflow opening 28 in the region of the upper edge 27 of the hollow frame 15, which leads the supplied air behind the inner skin 29 of the curved wagon roof 30, from where it can exit through outflow openings 31. In this way, a further improvement in the distribution of the heated or conditioned air in the compartment can be achieved under certain circumstances.
