EP4126626B1 - Double-leaf door device for a vehicle - Google Patents

Description

The invention relates to a door device for the interior of a passenger vehicle and to a passenger vehicle with at least one door device, comprising a double-leaf sliding door with a first door leaf and a second door leaf in one plane.

Interior doors in rail vehicles are often used to divide passenger areas. Double-leaf sliding doors are also used for this purpose.

The WO 2010/130537 A1 relates to a generic door device for the interior of a passenger vehicle.

The EP 2 634 063 A1 reveals a solution for interior sliding doors for rail vehicles that requires only a small amount of installation space in the vehicle's longitudinal direction for the guide rails of the door leaves.

Particularly in double-decker vehicles, there is little space available for interior door drives in the upper deck due to the strongly curved bodyshell structure in the roof area, especially in a vertical axis of the vehicle on the sides of the vehicle.

The invention is based on the object of specifying a door arrangement which takes up only a small installation space in terms of width.

The problem is solved by the subject matter of independent patent claim 1. Further developments and embodiments of the invention can be found in the features of the dependent patent claims.

A door device according to the invention is designed to be suitable for an interior of a passenger transport vehicle and comprises a first door leaf and a further, second door leaf, which lie in a common plane and are displaceable in this plane. To open the closed door device, the door leaves are pushed apart from a closed position in opposite directions to one another into an open position. To close the opened door device, the door leaves are pushed from the open position in opposite directions to one another into the closed position. The front main closing edges of the door leaves, which point towards one another, lie flush against one another in the closed position.

Furthermore, according to the invention, the door device comprises an upper guide for the first door leaf and an upper guide for the second door leaf, which are arranged parallel to one another and in particular also parallel to the plane in which the door leaves lie. The plane in which the door leaves lie can also be referred to as the door leaf plane. At least one upper guide is arranged offset from the door leaf plane. It therefore has a distance, measured perpendicular to the door leaf plane, greater than zero. The upper guide for the first door leaf can also be referred to as the first guide and the upper guide for the second door leaf can be referred to as the second guide. In particular, both the first guide and the second guide are arranged offset from the door leaf plane.

The invention further relates to a passenger transport vehicle, in particular a track-bound vehicle, for example a rail vehicle, comprising at least one door device according to the invention. The door device is provided in particular in an interior of the public transport vehicle between two interior parts, for example to separate two passenger compartments. The door device then acts as an interior door. The door leaf plane, for example, runs vertically in the transverse direction of the vehicle. The Door leaves can then be moved in the transverse direction of the vehicle.

The upper guides can be designed identically or with the same construction. The upper guides can each be designed as a straight guide, in particular as a linear guide, and in a further development comprise at least one guide rail and at least one sliding or running body guided along the at least one guide rail. The guide rails can be designed as profile rails and the sliding or running bodies as bushings. The guide rails can also be designed as open hollow rails with internally mounted rollers as running bodies. A stable roller carriage is advantageously used as the running body.

In addition to the first upper guide of the first door leaf and the second upper guide of the second door leaf, the door leaves can also be guided displaceably along a, in particular common, in particular rectilinear, lower guide. For example, they are guided in a lower rail. The upper guides are arranged above the door leaves in a predetermined installation position of the door device. The lower guide is arranged accordingly in the specified installation position of the door device in the lower area of the door leaf.

The upper guides and the lower guide guide the door leaves in the specified installation position at least horizontally and in particular transversely to a longitudinal direction of the vehicle.

According to a further development of the invention, the upper guides, in particular the respective guide rails, are arranged on different sides of the door leaf level.

A further development provides that the upper guides, in particular the respective guide rails, have a horizontal plane and the plane of the door leaves intersects the horizontal plane spanned by the upper guides in the middle between the upper guides. The distances between the door leaves and the upper guides are then the same, measured perpendicular to the door leaf plane.

In a further development, the upper guides each have at least one guide rail and at least one sliding or running body guided along the at least one guide rail, wherein the door leaves are each connected to the corresponding sliding or running body of the respective upper guide guided along the guide rail. The door leaves are slidably mounted along the upper guides by means of the sliding or running bodies. The upper guides can be designed, for example, as roller guides, wherein the first door leaf is connected to first rollers guided along the first guide or to a first roller carriage and the second door leaf is connected to second rollers guided along the second guide or to a second roller carriage.

In a further development, the sliding or running body of the upper first guide, to which the first door leaf is connected, is arranged at least partially in front of the first door leaf in the direction of a closing movement of the first door leaf from an open position to a closed position. In a similar development, the sliding or running body of the upper second guide, to which the second door leaf is connected, is also arranged at least partially in front of the second door leaf in the direction of a closing movement of the second door leaf from an open position to a closed position. The sliding or running bodies, for example the roller carriages, are arranged at least partially, in particular completely, in front of the main closing edges of the respective door leaves in the horizontal direction and in particular parallel to the guide rails.

According to one embodiment of the invention, the sliding or running bodies are like this in the direction of movement of the door leaves arranged offset so that they are arranged in a closed position of the door device at the level of the other door leaf.

To bridge gaps between the door leaves and the respective upper guides, arms can be provided between the door leaves and the respective upper guides, in particular the respective sliding or running bodies. The respective arms therefore serve to connect the sliding or running bodies to the respective door leaves and thus to bridge the gaps in the horizontal direction, in particular in the longitudinal direction of the vehicle, but also in the transverse direction of the vehicle.

In a further development, the first upper guide, in particular the first guide rail, and the second upper guide, in particular the first guide rail, are designed to be the same length. They are advantageously only as long as the door leaves can be moved between an open and a closed position. Due to the parallel arrangement, they can be designed to be relatively short.

According to a further development, the door leaves are connected to one another via a gear mechanism in such a way that they move in opposite directions between the closed and open positions. The coupling via the gear mechanism causes the door leaves to move in opposite directions. The movement of one door leaf between the closed and open positions leads to the other door leaf moving in the opposite direction.

The transmission can be further developed as a traction drive with a, in particular closed, belt or a chain, wherein the belt or the chain comprises driver elements via which the door leaves can be or are connected to the belt or the chain at least indirectly, for example via the arms. The driver elements engage, for example, on the arms, so that the respective Door leaves are indirectly connected to the driver elements via the respective arms. The traction drive is advantageously designed as a belt drive with a drive belt, in particular a toothed belt.

The belt or chain can rotate between, above or below the upper guides, in particular the guide rails, via deflection rollers arranged laterally next to the end faces of the guides to deflect the belt or chain. The closed belt or chain wraps around the deflection rollers.

Advantageously, the traction drive is arranged at least partially, in particular centrally, for example completely, between the upper guides.

If the traction drive is arranged centrally, the pulleys for the belt or chain around which the belt or chain rotates are aligned with the upper guides in such a way that their central axes, around which the pulleys rotate, lie in the plane of the door leaf. In a given installation position in the vehicle, the central axes run parallel to a vertical axis of the vehicle.

The deflection rollers are advantageously arranged on both sides offset from the upper guides, so that a deflection roller is provided in the area of each end face of the upper guides.

The door device preferably comprises a door drive for power-operated displacement of the door leaves. The door drive comprises in particular an electric motor. The door leaves are displaced by the electric motor.

It is advantageous if the traction mechanism is powered by the door drive. It is connected to the door drive in a suitable manner. In particular, the door drive is free of a linear drive.

The door drive can also be arranged between the upper guides.

The vehicle according to the invention is further developed as a double-decker rail vehicle, wherein the door device is arranged in an upper floor of the double-decker rail vehicle.

The door device can be bordered laterally by partitions which run parallel to the door leaves.

A further development of the vehicle according to the invention provides that the upper guide for the first door leaf and the upper guide for the second door leaf are arranged between a ceiling of the vehicle and a roof of the vehicle.

The upper guides for the first and second door leaves are spatially separated from each other. They are offset horizontally and perpendicular to the respective guide direction to the door leaves, on different sides of the door leaf level and thus spaced apart from each other and spaced from the door leaf level. This makes it possible to make the upper guides very short. The door drive can thus be positioned very high in the area of a rounded roof of the vehicle in order to achieve the greatest possible clearance height in the interior of the vehicle. The opening and closing movements of the door leaves are synchronized, for example, via a centrally arranged toothed belt. The drive can also take place via the toothed belt. The arrangement of a motor-gear unit of the door drive can be arbitrary.

In Fig.1 the upper floor of a car body of a double-decker rail vehicle for public transport according to the invention with a door device according to the invention is shown in cross section. The roof 14 of the car body of the rail vehicle and a ceiling 13 that delimits the interior, in particular the passenger compartment, of the car body at the top can be seen. The ceiling 13 can also form a lower edge of a door lintel. In addition, a first door leaf 1, 1' - here only the left one for the sake of clarity - of a double-leaf interior sliding door of the door device is shown. The double-leaf sliding door serves to separate two interior spaces from one another. In a closed position of the double-leaf sliding door, the first door leaf 1 is drawn with solid lines. In an open position in the schematic representation, the first door leaf 1' is sketched in dashed lines. This nomenclature also applies to other movable components. The first door leaf 1, 1` lies in a vertical plane in which a vertical axis and a transverse axis of the car body run.

In the ceiling or roof area, i.e. between the ceiling 13 and the roof 14 of the car body, an upper first guide 3 of the first door leaf 1, 1' is arranged. It comprises a first guide rail along which a first running body 11, 11', for example a roller carriage, is guided in a displaceable manner. The first door leaf 1, 1' is connected to the first running body 11, 11' via a first arm 5, 5' in a suitable manner. In this schematic cross section, the first The running body 11, 11' is arranged in the closing direction of the first door leaf 1, 1' from an open position (1') to a closed position (1) in front of the first door leaf 1, 1', i.e. offset in the transverse direction of the vehicle from the first door leaf 1, 1'. In the opening direction, it trails accordingly. The first arm 5, 5' serves to bridge the distance between the first running body 11, 11' and the first door leaf 1, 1' in the transverse direction of the vehicle.

In addition, in this exemplary embodiment, a closed drive belt, here a toothed belt 8, is provided in the roof or ceiling area of the car body. It is designed to run around and wrap around deflection rollers 9. As explained 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 engage the first arm 5, 5'. When the first door leaf 1, 1` opens or closes, the closed toothed belt 8 is moved around the deflection rollers. Conversely, a force is exerted by the toothed belt 8 moving around the deflection rollers on the first door leaf 1, 1', which is used to open and close this or the double-leaf sliding door. A door drive is provided for this purpose, which is also placed in the roof or ceiling area of the car body and is connected to the toothed belt 8 or the deflection rollers 9. For the sake of simplicity, this is omitted from the drawings.

Of course, these statements regarding the first door leaf 1, 1` also apply analogously to a second door leaf 2, 2' of the double-leaf sliding door, as in the Fig. 2 and Fig. 3 shown. Fig. 2 illustrates the double-leaf sliding door in the closed position, the Fig. 3 equally in the open position. The reference numerals 2, 6 and 12 identify the second door leaf 2, a second arm 6 and a second running body 12 in the closed position, 2', 6' and 12' refer accordingly to the above-mentioned positions in the open position.

In the closed position according to Fig. 2 It can be clearly seen that both respective running bodies 11 and 12 are offset in the direction of movement to the corresponding door leaves 1 and 2 in the transverse direction of the vehicle in such a way that they are at the level of the other door leaf 1, 2 and lie parallel to it.

Difficult to see in cross sections, but in Fig.4 , which shows the door device according to the invention, it is clear 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 offset from one another perpendicular to the respective guide direction for the door leaves 1, 1' and 2, 2`, on different sides of a plane of the door leaves 1, 1' and 2, 2` and are thus spaced apart from one another and spaced from the door leaf plane. The door leaves 1, 1' and 2, 2` are thus offset from the respective running body 11, 11` and 12, 12' not only in the transverse direction of the vehicle and thus in the direction of movement of the door leaves 1, 1' and 2, 2', but also in the longitudinal direction of the vehicle and thus perpendicular to the door leaf plane. The respective guide rails of the upper guides 3 and 4 run parallel to each other and parallel to the plane of the door leaves 1, 1' and 2, 2'. Here, 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 the second door leaf 2, 2' is arranged centrally, i.e. with the same distance between them. The respective distances in the longitudinal direction of the vehicle 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'.

The traction drive with the toothed belt 8 and the pulleys 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. The axes of the deflection rollers 9 are in the plane of door leaves 1, 1' and 2, 2'.

The door leaves 1, 1' and 2, 2' are attached to driver elements 10, 10' of the toothed belt 8 via the arms 5, 5' and 6, 6'. These are arranged on the oppositely moving sections of the toothed belt 8 which wraps around the deflection rollers 9 between the deflection rollers 9, so that the door leaves 1, 1 'and 2, 2' move and thus the inner door opens or closes.

Due to the separation of the upper guides 3, 4 and the respective horizontal and vertical offset of the door leaves 1, 2 to their running bodies 11, 12, the guides 3, 4 can be designed to be short and therefore take up little installation space in the transverse direction of the vehicle, which is particularly advantageous in the upper deck of double-deck vehicles due to the roof line that slopes sharply to the side.
