Description

[0034] FIG. 1 shows schematically a vehicle according to the invention in cross section,

[0035] FIG. 2 shows the vehicle of FIG. 1 with the two door leaves in the closed position,

[0036] FIG. 3 shows the vehicle of FIG. 1 with the two door leaves in the open position,

[0037] FIG. 4 shows schematically the vehicle according to the invention in a horizontal longitudinal section.

[0038] In FIG. 1 the upper deck of a car body of a double-decker rail vehicle according to the invention of the public passenger transport system is shown with a door device according to the invention in cross section. The roof 14 of the car body of the rail vehicle can be seen, as well as a ceiling 13 defining the interior toward the top, in particular the passenger compartment, of the car body. The ceiling 13 can also form a lower edge of a door lintel. Moreover, a first door leaf 1, 1′ of a double-leaf inner sliding door of the door device is illustrated - here only the left-hand door leaf for the sake of clarity. The double-leaf sliding door serves for separating two interiors from one another. In a closed position of the double-leaf sliding door, the first door leaf 1 is illustrated by solid lines. In an open position in the schematic view, the first door leaf 1′ is sketched in dashed lines. This nomenclature also applies to further displaceable components. The first door leaf 1, 1′ is located in a vertical plane in which a vertical axis and a transverse axis of the car body run.

[0039] An upper first guide 3 of the first door leaf 1, 1′ is arranged in the ceiling region or roof region, i.e. between the ceiling 13 and the roof 14 of the car body. The upper first guide comprises a first guide rail along which a first running body 11, 11′, for example a guide roller carriage, is displaceably guided. The first door leaf 1, 1′ is connected in a suitable manner to the first running body 11, 11′ via a first arm 5, 5′. In this schematic cross section, the first running body 11, 11′ is arranged in the closing direction of the first door leaf 1, 1′ from an open position (1′) into a closed position (1) upstream of the first door leaf 1, 1′, i.e. offset with respect to the first door leaf 1, 1′ in the vehicle transverse direction. In the opening direction, the first running body is correspondingly arranged downstream.

[0040] The first arm 5, 5′ serves for bridging the spacing between the first running body 11, 11′ and the first door leaf 1, 1′ in the vehicle transverse direction.

[0041] Moreover, in this exemplary embodiment a closed drive belt, in this case a toothed belt 8, is provided in the roof region or ceiling region of the car body. The toothed belt is designed to circulate and to be wound around deflection rollers 9. As set forth in more detail below, the first door leaf 1, 1′ and thus also the first running body 11, 11′ are connected to the toothed belt 8 via driver elements on the toothed belt 8 which act on the first arm 5, 5′. During opening or closing movements of the first door leaf 1, 1′, the closed toothed belt 8 is moved in a circulating manner around the deflection rollers. Conversely, a force is applied by the toothed belt 8, which is moved in a circulating manner around the deflection rollers, onto the first door leaf 1, 1′ which is used in order to open and to close this first door leaf or the double-leaf sliding door. To this end, a door drive is provided, said door drive also being positioned in the roof region or ceiling region of the car body and being connected to the toothed belt 8 or the deflection rollers 9. This is omitted in the drawings for the sake of simplicity.

[0042] Naturally, these embodiments relative to the first door leaf 1, 1′ also apply equally to a second door leaf 2, 2′ of the double-leaf sliding door, as shown in FIG. 2 and FIG. 3. FIG. 2 illustrates the double-leaf sliding door in the closed position, FIG. 3 equally in the open position. The reference numerals 2, 6 and 12 in this case denote the second door leaf 2, a second arm 6 and a second running body 12 in the closed position, and the reference numerals 2′, 6′ and 12′ in this

[0043] case refer accordingly to the aforementioned positions in the open position.

[0044] In the closed position according to FIG. 2 it can be clearly identified that both respective running bodies 11 and 12 are offset in the direction of movement to the respective corresponding door leaves 1 and 2 in the vehicle transverse direction, such that they are located level with the respective other door leaf 1, 2 and are located parallel thereto.

[0045] While it is difficult to identify it in the cross sections, it is illustrated in FIG. 4, which shows the door device according to the invention, that the first upper guide 3 for the first door leaf 1, 1′ is spatially separated from a second upper guide 4 for the second door leaf 2, 2′. The upper guides 3, 4 are arranged offset to one another perpendicularly to the respective guide direction of the door leaves 1, 1′ and 2, 2′ on different sides of a plane of the door leaves 1, 1′ and 2, 2′ and thus arranged spaced apart from one another and spaced apart from the door leaf plane. Thus the door leaves 1, 1′ and 2, 2′ are not only offset in the vehicle transverse direction and thus in the direction of movement of the door leaves 1, 1′ and 2, 2′ but also offset to the respective running body 11, 11′ and 12, 12′ in the vehicle longitudinal direction and thus perpendicularly to the door leaf plane. The respective guide rails of the upper guides 3 and 4 run parallel to one another and parallel to the plane of the door leaves 1, 1′ and 2, 2′. In this case, the guide rails of the first upper guide 3 and the second upper guide 4 are arranged such that the plane of the first door leaf 1, 1′ and of the second door leaf 2, 2′ is arranged centrally therebetween, i.e. with the same spacing in each case. The respective spacings in the vehicle longitudinal direction between the door leaves 1, 1′ and 2, 2′ and their respective running bodies 11, 11′ and 12, 12′ are in turn bridged by the respective arms 5, 5′ and 6, 6′.

[0046] The traction drive 7 with the toothed belt 8 and the deflection rollers 9 is also arranged centrally between the upper guides 3, 4. The vertical plane of the door leaves 1, 1′ and 2, 2′ intersects the imaginary horizontal plane, in which both guides 3, 4 are located, centrally between the guides 3, 4.

[0047] The axes of the deflection rollers 9 are located in the plane of the door leaves 1, 1′ and 2, 2′.

[0048] The door leaves 1, 1′ and 2, 2′ are fastened via the arms 5, 5′ and 6, 6′ to driver elements 10, 10′ of the toothed belt 8. These driver elements are arranged between the deflection rollers 9 on the portions which move in opposing directions of the toothed belt 8 which is wound around the deflection rollers 9 so that the door leaves 1, 1′ and 2, 2′ are moved and thus the inner door opens or closes.

[0049] By separating the upper guides 3, 4 and the respective horizontal and vertical offset of the door leaves 1, 2 to the running bodies 11, 12 thereof, the guides 3, 4 can be of short design and thus take up less installation space in the vehicle transverse direction, which is advantageous, in particular, in the case of double-decker vehicles in the upper deck by the roof line sloping steeply to the side.
