Description

[0001] The invention relates to a transition door device for a public transport vehicle with a corridor canal and to a vehicle with a transition door device.

[0002] Large-capacity vehicles, such as passenger rail vehicles, can have a corridor canyon to allow level passage through the entire vehicle while still accommodating technical components such as chassis.

[0003] Transitional door devices have become popular for separating individual carriages or passenger areas within a carriage of a large-capacity vehicle. They are typically located in areas of the vehicle with a continuous floor level across the entire width.

[0004] The publication FR 2 397 299 A1 teaches a generic gangway door device for a public transport vehicle with a passageway. The gangway door device has an upper part with two opposingly movable door leaves and a lower part with door panels pivotally attached to each of the door leaves.

[0005] The published patent application DE 10 2023 200 487 A1, which was not yet accessible to the public at the priority date of this patent application, also discloses a generic transition door device with an upper and a lower part, wherein the upper part has two door leaves that can be moved in opposite directions and the lower part comprises covers that can be inserted into each of the door leaves.

[0006] The invention is based on the object of proposing a transition door device that can be flexibly arranged in the vehicle.

[0007] The problem is solved by the subject matter of the independent patent claims. Further developments and refinements of the invention are found in the features of the dependent patent claims.

[0008] A transition door device according to the invention for a vehicle, in particular for a large-capacity vehicle of public passenger transport, in particular for a rail vehicle, comprising at least one aisle channel comprises an upper part and a lower part, wherein the upper part has two door leaves which can be displaced in opposite directions and the lower part has two door leaves which can be pivoted in opposite directions.

[0009] A vehicle according to the invention, in particular a large-capacity vehicle for public passenger transport, in particular a rail vehicle for public passenger transport, has at least one car body with an aisle channel and at least one transition door device according to the invention, wherein the upper part of the transition door device, i.e. at least the two door leaves that can be moved in opposite directions, are arranged at least partially, in particular completely, above a seating level and the lower part, i.e. at least the two door leaves that can be pivoted in opposite directions, are arranged at least partially, in particular completely, in the aisle channel.

[0010] The two counter-sliding door leaves are arranged, in particular, above the seating level in the manner of a double-leaf sliding door, aligned with one another, and can be moved between a closed and an open state. The two door leaves can be moved in a common plane. They perform a counter-sliding translational movement. Likewise, the two counter-swivelling door leaves are arranged, in particular, in the manner of a double-leaf swing door, in the aisle canal, aligned with one another, and can be pivoted between a closed and an open state. A pivoting movement of a door leaf is understood here to mean a movement of the door leaf with a rotational movement component around an axis parallel to the plane of the door leaf.When closed, the two door leaves lie in a common plane, in particular when closed they lie in a common plane with the door wings, in particular a cross-sectional plane through the vehicle body which is essentially vertical when the transition door device is in the intended orientation. An aisle which is lower between the seating levels is referred to as an aisle. The seating levels are preferably located in a common plane which runs in particular horizontally, provided the vehicle is also aligned horizontally. The floor of the aisle preferably serves as a floor for passengers and is aligned in particular parallel to the seating levels; it could also be referred to as the aisle level. In this case, it is lower than the seating levels. The sides of the aisle are closed off at the top, in particular by the seating levels.The aisle is defined by the floor and the sides of the aisle, which can also be referred to as the opposing side walls of the aisle. When the transition door device is closed, the door leaves seal off the aisle, and when open, they allow passage. The space above the aisle above the seating level is opened by the door leaves for passage, and blocked when closed.

[0011] The transition door device thus closes at both aisle level and seat level. The upper part extends from the seat level to or below a vehicle ceiling. When open, the door leaves can be guided behind a bulkhead panel or behind end walls of an interior bulkhead arranged on either side of the transition door device. The lower part extends from the aisle level to the seat level. When open, the door leaves can be pivoted to the sides of the aisle channel. They perform a pivoting or a rotating-sliding movement between the closed and open states. Their movement therefore has at least a rotational component. Accordingly, the door leaves could also be referred to as door flaps.

[0012] In order to effect a mutually dependent opening and closing movement of the door leaves with the door wings, a first door leaf of the two oppositely pivoting door leaves is advantageously mechanically coupled to a first door leaf of the two oppositely displaceable door leaves and a second door leaf of the two oppositely pivoting door leaves is mechanically coupled to a second door leaf of the two oppositely displaceable door leaves, in particular such that a sliding movement of the first door leaf causes a pivoting movement of the first door leaf and a sliding movement of the second door leaf causes a pivoting movement of the second door leaf.

[0013] According to a further development of the invention, the first door leaf is mechanically coupled to the first door leaf in the region of a main closing edge of the first door leaf so as to be rotatable relative to the first door wing in the region of a main closing edge of the first door wing, and the second door leaf is mechanically coupled to the second door leaf in the region of a main closing edge of the second door leaf so as to be rotatable relative to the second door wing in the region of a main closing edge of the second door wing.

[0014] For this purpose, the first door leaf can be connected to the first door wing via a fixed bearing point, in particular a first pivot joint, for example a hinge joint. Similarly, the mechanical coupling between the second door leaf and the second door wing can be realized via a fixed bearing point, in particular a second pivot joint, for example a hinge joint.

[0015] In the closed state of the transition door device, i.e., in the closed state of the two counter-sliding door leaves and in the closed state of the two counter-pivoting door leaves, not only do the respective main closing edges of the two counter-sliding door leaves and the two counter-pivoting door leaves face each other, possibly forming a small gap, but the main closing edges of the first door leaf and the first door leaf are preferably substantially in line, and the main closing edges of the second door leaf and the second door leaf are also preferably substantially in line. The respective upper secondary closing edge of the two counter-pivoting door leaves and the respective lower secondary closing edge of the two counter-pivoting door leaves are also preferably in line with each other in the closed state of the transition door device, possibly forming a small gap.

[0016] As already explained above, the door leaves can be pivoted, in particular, toward the respective sides of the aisle when open. This is achieved, in particular, via a rotary-sliding movement, which is realized, for example, via a crank mechanism connected to the aisle and the respective door leaf. The crank mechanisms guide the door leaves on a curved guide track between an open and a closed state under the action of force. The door leaves are, in a sense, positively guided when the door leaves move.

[0017] The crank mechanism can be designed as a linkage, particularly a four-link linkage, such as a so-called push-link hinge. Other multi-joint hinges are also conceivable.

[0018] As already described above, the pivoting movement of the first and second door leaves can have not only rotational but also translational components and can therefore be referred to as a pivoting-sliding movement or a rotating-sliding movement. The respective pivoting or rotational axis around which the respective pivoting movement of the respective first and second door leaves is carried out between the closed and open state is not perpendicular to the plane of the respective door leaf, but rather lies parallel to the plane of the respective door leaf. In the intended orientation or installation position of the transition door device, the pivoting or rotational axes of the first and second door leaves can run parallel to one another in the vertical direction.

[0019] This offers several advantages over the prior art. Previous solutions lack stability, particularly against external impacts perpendicular to the door leaves of the lower section when closed. They are not vandal-proof. The impact of the door leaves during the opening movement leads to increased wear. Both of these effects can lead to a "wearing out" of the connection between the door leaves of the lower section and the door leaves of the upper section, thus requiring increased maintenance. Furthermore, the door leaves of the lower section are not tamper-proof and are therefore disadvantageous for fire safety reasons. These disadvantages are overcome by the invention. The door leaves of the lower section cannot be moved independently of the door leaves of the upper section when the transition door device is in operation, since the first door leaf is connected to the first door leaf, and the second door leaf is connected to the second door leaf.For maintenance purposes, these connections can be designed to be detachable so that in a maintenance condition the door leaves can be moved independently of the door wings.

[0020] According to a further development, the transition door device has at least one first gear element mounted on the first door leaf, in particular rotatably, for forming a first four-membered coupling mechanism, in particular a thrust rocker, which in particular acts horizontally or horizontally, with the first door leaf as a further gear element of the first four-membered coupling mechanism, and at least one second gear element mounted on the second door leaf, in particular rotatably, for forming a second four-membered coupling mechanism, in particular a thrust rocker, which in particular acts horizontally or horizontally, with the second door leaf as a further gear element of the second four-membered coupling mechanism.

[0021] In the properly installed state of the transition door device in the vehicle, the first door leaf is mounted via the first gear element and the second door leaf is mounted via the second gear element on opposite sides of the aisle channel.

[0022] According to a further development, the transition door device has a first pivot arm as the first gear element and a second pivot arm as the second gear element, wherein a first end of the first pivot arm is arranged on the first door leaf in order to form the first four-membered coupling mechanism, in particular a thrust rocker, in particular centrally, between the main closing edge and a rear secondary closing edge of the first door leaf opposite the main closing edge, so as to be rotatable relative to the first door leaf, wherein a second end of the first pivot arm, opposite the first end of the first pivot arm, is arranged on the corridor channel, in particular on a first side orSide wall of the aisle, and wherein a first end of the second pivot arm for forming the second four-membered coupling mechanism, in particular a thrust rocker, is arranged in particular centrally between the main closing edge and a rear secondary closing edge of the second door leaf opposite the main closing edge on the second door leaf so as to be rotatable relative to the second door leaf, wherein a second end of the second pivot arm opposite the first end of the second pivot arm is designed for rotatably mounting the second pivot arm on the aisle, in particular on a second side or side wall of the aisle.

[0023] The first pivot arm is arranged, in particular, via a further pivot joint in the region of its first end on the first door leaf, wherein at its second end it has a part of a further pivot joint for rotatably supporting it on the aisle channel. Similarly, the second pivot arm is arranged, in particular, via a further pivot joint in the region of its first end on the second door leaf, wherein at its second end it has a part of a further pivot joint for rotatably supporting it on the aisle channel.

[0024] In the properly assembled state of the transition door device in the vehicle, the first door leaf is then hinged via the first pivot arm to a first side or a first side wall of the aisle channel, wherein the second door leaf is hinged via the second pivot arm to a second side or a second side wall of the aisle channel opposite the first side or a first side wall.

[0025] Alternatively, the first and second pivot arms are each rotatably mounted at the floor of the aisle in the area of ​​the respective side of the aisle. They are then designed accordingly for rotatable mounting at the floor of the aisle.

[0026] Alternatively, the four-membered coupling mechanism can also be designed as follows: The transition door device has, in a further development, a first guide rail for guiding a first push block as the first gear element and a second guide rail for guiding a second push block as the second gear element, wherein the first and the second guide rail are designed for arrangement on the corridor channel and wherein the first push block is arranged on the first door leaf in order to form a four-membered coupling mechanism in the region of a secondary closing edge of the first door leaf opposite the main closing edge and is guided in the first guide rail, and wherein the second push block is arranged on the first door leaf in order to form a four-membered coupling mechanism in the region of a secondary closing edge of the first door leaf opposite the main closing edge

[0027] Secondary closing edge of the second door leaf is arranged on the second door leaf and guided in the second guide rail.

[0028] In the properly assembled state of the transition door device in the vehicle, the first guide rail can then be arranged on a first side or a first side wall of the aisle channel, wherein the second guide rail can be arranged on a second side or a second side wall of the aisle channel opposite the first side or a first side wall.

[0029] Alternatively, the guide rails can also be arranged on or in the floor of the aisle in the area of ​​the respective side of the aisle.

[0030] The sliding blocks, or slot blocks if the guide rails are designed with a hollow chamber or groove profile, can be guided so that they can move along the respective guide rail. They can also be mounted so that they can rotate in the respective guide rails. In this case, they are not necessarily connected to the corresponding door leaves in a way that they can rotate relative to the latter. If, on the other hand, they are guided so that they can move exclusively along the respective guide rail, they are mounted on them so that they can rotate relative to the door leaves. In a further development, the first sliding block is arranged on the first door leaf so that it can rotate relative to the first door leaf, and the second sliding block is arranged on the second door leaf so that it can rotate relative to the second door leaf.

[0031] The previously outlined design of the four-link coupling gear with swivel arms has the advantage that it is free of guide rails on the floor and also on the side walls of the aisle.

[0032] Advantageously, the vehicle is free of guide rails on a floor of the aisle and / or on the seating levels for guiding the two door wings and / or the two door leaves. In a further development, the transition door device is arranged in the vehicle such that, when the transition door device is open, the first and second door wings are pushed apart approximately transversely to the aisle, and the first door leaf is pivoted toward the first side of the aisle, and the second door leaf is pivoted toward the second side of the aisle opposite the first side, so that the aisle is clear for passage.

[0033] A sufficiently large passage width should be achieved. Accordingly, the components of the transition door device are advantageously dimensioned relative to one another such that the lower part of the transition door device, when fully opened, in particular the first door leaf essentially rests against the first side of the corridor and the second door leaf essentially rests against the second side of the corridor, naturally forming a gap therebetween, in particular with the first or second pivot arm between the side of the corridor and the door leaf. In the open position, the door leaves are at an angle of greater than 75°, in particular greater than 80°, in particular greater than 85°, in particular almost 90° to the door wings. They are therefore at an angle of less than 15°, in particular less than 10°, in particular less than 10° to the corresponding sides of the corridor, in particular they run approximately parallel to the sides of the corridor.The main closing edges of the first door leaf and the first door panel can be approximately aligned even when open, but then offset by up to 90°. The same logically applies to the main closing edges of the second door leaf and the second door panel when open.

[0034] According to a further development, a distance between the mechanical coupling of the first door leaf to the first door wing and the first end of the first pivot arm, as well as a distance between the first and second ends of the first pivot arm, i.e. the length of the first pivot arm, are coordinated with one another such that the first door leaf, in an open position, is at an angle of less than 15°, in particular less than 10°, in particular less than 5°, to the first side of the aisle. Likewise, a distance between the mechanical coupling of the second door leaf to the second door wing and the first end of the second pivot arm, and the length of the second pivot arm between the first and second ends of the second pivot arm are coordinated with one another such that the second door leaf, in an open position, is at an angle of less than 15°, in particular less than 10°, in particular less than 5°, to the second side of the aisle.In the open position, the door leaves are pivoted toward the respective sides of the corridor, thus clearing the corridor for passage. Advantageously, the first door leaf is approximately parallel to the first side of the corridor in the open position. Similarly, the second door leaf is essentially parallel to the second side of the corridor in the open position.

[0035] In a further development, the transition door device comprises at least one door drive connected to the first and second door leaves and configured to move the first and second door leaves in opposite directions between a closed and an open position. This drive is, for example, an electric motor drive.

[0036] The lower part of the transition door device, however, is further developed and is free of its own direct drive, in addition to the drive of the door leaves, for carrying out the movement, in particular the pivoting or turning-sliding movement, of the door leaves. The door leaves are moved along with the door leaves by the mechanical couplings acting as drivers. The drive for the door leaves thus also causes an opening and closing movement of the door leaves. The transverse movement of the door leaves in the upper part of the transition door device is converted into the respective pivoting or turning-sliding movement of the door leaves in the lower part of the transition door device by means of the mechanical couplings with the door leaves and the respective bearings of the door leaves or their design as four-link coupling gears.

[0037] The inventive transition door device and the vehicle according to the invention have several advantages. It enables an almost complete opening of the aisle without retractable door panels in the side walls of the aisle, and thus without cutouts in the side walls of the aisle. The installation space in the aisle is very limited. Separate door drives are also not required; a single drive for opening and closing the transition door device, which is divided into a lower and an upper section, is sufficient. Without rails in the floor or on the seating levels, it is well protected against dirt and therefore offers high availability.

[0038] The invention permits numerous embodiments. It is explained in more detail with reference to the following figures, each of which illustrates an exemplary embodiment. Identical elements in the figures are provided with the same reference numerals. Fig. 1 shows a schematic cross section through the aisle area of ​​a vehicle with an aisle canyon, Fig. 2 shows a schematic view of a transition door device according to the invention in the intended installation position in the closed state, Fig. 3 shows a schematic view of the transition door device from Fig. 2 in partial section, Fig. 4 shows schematically the transition door device according to the invention in the intended installation position in a partially opened state, Fig. 5 shows schematically the transition door device from Fig. 4 in partial section, Fig. 6 shows schematically the transition door device according to the invention in the intended installation position in the open state, Fig. 7 shows schematically the transition door device from Fig. 6 in partial section,

[0039] In Fig. 1is a schematic cross-sectional view of an interior of a vehicle, in particular a passenger compartment of a rail vehicle for public transport. The interior has an aisle 2. The aisle 2 is bounded at the bottom by a floor 21, here a floor as part of an aisle for passengers of the vehicle, and laterally by a first side 22 and by a second side 23 opposite the first side 22. The sides 22 and 23 can be parts of platforms in which devices or components of the vehicle are housed, for example, wheels of a chassis of the vehicle run in the platforms, and on which platforms seats can be arranged. Therefore, the floor of the vehicle above the platforms is also referred to as the seating level 10. The seating levels 10 are raised compared to the floor 21 of the aisle.

[0040] The Figures 2 to 7now illustrate a transition door device 1 according to the invention, which is at least partially arranged in the region of the corridor canal 2. The transition door device 1 comprises an upper part 11 and a lower part 12, wherein the upper part 11 has two door leaves 3, 5 which can be moved in opposite directions between a closed state and an open state, a first movable door leaf 3 and a second door leaf 5 which can be moved in opposite directions to the first door leaf 3, and the lower part 12 has two door leaves 4, 6 which can be pivoted in opposite directions between a closed state and an open state, a first pivotable door leaf 4 and a second door leaf 6 which can be pivoted in opposite directions to the first door leaf 4.

[0041] In this case, each door leaf 4, 6 is mechanically coupled to a respective door leaf 3, 5, the first door leaf 4 is mechanically coupled to the first door leaf 3 and the second door leaf 6 is mechanically coupled to the second door leaf 5. This results in a mutually dependent opening and closing movement of the door leaves 4, 6 with the door leaves 3, 5, as shown in the Figures 2 to 7 can be seen. A sliding movement of the first door leaf 3 is converted into a pivoting movement of the first door leaf 5, and a sliding movement of the second door leaf 4 is converted into a pivoting movement of the second door leaf 6.

[0042] Here, the first door leaf 4 is mechanically coupled to the first door leaf 3 in the area of ​​the main closing edge 31 of the first door leaf 3 via a first pivot joint 42 in the area of ​​the main closing edge 41 of the first door leaf 4. Similarly, the second door leaf 6 is mechanically coupled to the second door leaf 5 in the area of ​​the main closing edge 51 of the second door leaf 5 via a second pivot joint 62 in the area of ​​the main closing edge 61 of the second door leaf 6.

[0043] In addition, a first pivot arm 45 and a second pivot arm 65 are provided. The pivot arms 45, 65 are each arranged centrally between the main closing edges 41, 61 of the door leaves 4, 6 and the rear secondary closing edges 46, 66 of the door leaves 4, 6, which are opposite the main closing edges 41, 61 of the door leaves 4, 6, and are rotatably mounted on the respective door leaf 4, 6.

[0044] The pivot arms 45, 65 are designed for rotatable mounting on the aisle channel 2 and are attached to the sides 22, 23 of the aisle channel 2. A first end of the pivot arms 45, 65 is connected to the door leaves 4, 6 via a pivot joint 43, 63, and a second end of the pivot arms 45, 65 is connected to the sides of the aisle channel via another pivot joint 44, 64.

[0045] Thus, in each case a four-link coupling mechanism is designed, here in the form of a sliding rocker, with the pivot arms 45, 65 as so-called sliding cranks and the respective sections of the door leaves 4, 6 between the articulated connections of the respective pivot arms 43, 63 and the rotary joints 42, 62 as mechanical couplings with the door leaves 3, 5 as further gear members.

[0046] In the closed state of the transition door device 1, according to Fig. 2 and Fig. 3, the door leaves 3, 5 and the door panels 4, 6 are each in a closed position and the first and second door leaves 3, 5 and the first and second door panels 4, 6 are in a common plane and the respective main closing edges 31, 41, 51, 61 as well as the upper secondary closing edges 48, 68 of the door leaves 4, 6 and the lower secondary closing edges 37, 57 of the door leaves 3, 5 run flush with one another and lie against one another, forming a small gap. The upper secondary closing edges 38, 58 of the door leaves 3, 5, on the other hand, point towards the ceiling. The lower secondary closing edges 47, 67 of the door leaves 4, 6 are opposite the floor 21 of the corridor 2.

[0047] The two door leaves 3, 5 can be moved in opposite directions, essentially transverse to the corridor channel. The mechanical coupling via the pivot joints 42, 63 ensures that the door leaves 4, 6 are driven along. The main closing edges 41, 61 of the door leaves 4, 6 move along a path that is essentially parallel to the direction of movement of the door leaves 3, 5 or even coincides with it. By linking the door leaves 4, 6 via the pivot arms 45, 65 on the sides 22, 23 of the corridor channel, they are moved in a rotating-sliding motion on a curved guide track.

[0048] In the partially opened state according to Fig. 4 and 5 The door leaves 3, 5 partially protrude into the corridor, which is extended upwards by the sides 22, 23 of the corridor canyon 2. Viewed from above, the door leaves 4, 6 are positioned diagonally in the corridor canyon and still partially block the corridor.

[0049] In the open state of the transition door device 1 according to Fig. 6 and 7 In contrast, the door leaves 3, 5 are approximately shifted out of the corridor, opening the corridor for passage through the transition door device 1. A small overlap can be accepted here, which is due to the mechanical coupling with the door leaves 4, 6. The door leaves 4, 6 are pivoted toward the sides 22, 23 of the corridor channel 2, so that a sufficiently large passage width is achieved—the corridor is open for passage through the transition door device 1.

[0050] The door leaves 4, 6 are aligned essentially parallel to the sides 22, 23 of the corridor 2 and are thus offset at an angle of approximately 90° to the door leaves.

[0051] In the area of ​​the transition door device 1, the vehicle may have an interior bulkhead (not shown here) with end walls on both sides, into which the door leaves 3, 5 are at least partially displaced or displaceable in the open position. The rear secondary closing edges 36, 56 of the door leaves 3, 5, opposite the respective main closing edges 31, 51 of the door leaves 3, 5, are then covered by the end walls at least on one side.

[0052] Regardless of the grammatical gender of a particular term, persons with male, female or other gender identities are included.
