EP3507161B1 - Device for sealing at least one door leaf for a rail vehicle, and rail vehicle - Google Patents

Description

The invention relates to a device for sealing at least one door leaf for a rail vehicle and a rail vehicle.

Sliding doors are preferred for rail vehicles. Due to their design, sliding doors run in an opening or closing direction along at least one guide rail. Abrasive seals can be used for sealing along this guide rail.

The EP 1 584 535 A1 discloses a pivoting sliding door for a rail vehicle with at least one door leaf displaceable in its longitudinal direction. In the immediate vicinity of the door frame, an angle lever for guiding and moving the door leaf in the transverse direction is rotatably mounted in a horizontal plane.

The DE 20 2008 004 518 U1 discloses a door system for a vehicle used in local and long-distance public transport with a door and a door portal, the door being moved essentially parallel to the outer wall of the vehicle when it is opened and closed.

The object of the invention is to provide an improved device for sealing at least one door leaf for a rail vehicle and an improved rail vehicle.

According to the invention, this object is achieved by a device for sealing at least one door leaf for a rail vehicle and a rail vehicle with the features of the main claims. Advantageous refinements and developments of the invention emerge from the following subclaims.

A device for sealing at least one door leaf for a rail vehicle is presented, the device having at least one displacement device which is designed to move the door leaf in the area of a closed position in a z-direction of the rail vehicle in order to counteract a sealing element of the door leaf To press counter-sealing element of a portal of the rail vehicle.

Grinding of seals in a sliding door or pivoting sliding door can be largely prevented if a door leaf of the sliding door does not come into contact with the seals during closing and only touches the seals as close as possible to a closed position. This can be achieved by moving the door leaf vertically. The door leaf can be moved in a closing direction using a guide system. In order to additionally achieve improved thermal insulation and additionally or alternatively improved sound insulation, a lifting device, also referred to as a lifting device, can be used, by means of which the door leaf can also be moved vertically so that the height movement can be carried out. The lifting device can be embodied as a component of the guide system or as an independent device, a device that can also be retrofitted according to one embodiment. Thus, according to different embodiments, the device for sealing can be understood to mean both an independent lifting device and a component of the guide system or the entire guide system.

The door leaf can be, for example, a door leaf of a sliding door or a pivoting sliding door. According to one embodiment, there is a modularity. Thus, according to one embodiment, the guide system for the door leaf can be equipped with the lifting device without changes or without significant changes. Thus, the lifting device can also be designed as a retrofittable unit. A customer can thus advantageously choose whether he wants a guide system "only" for opening and closing a door or also with improved sound or heat sealing by including the lifting device. This option can also advantageously be retrofitted at a later date. Thus, the device for sealing can comprise at least one retrofittable component which can be built into an existing door system in order to make the door system movable in the vertical and thereby enable improved sound insulation and / or thermal insulation.

The displacement device can be designed as an active component which is designed to move the door leaf in response to a movement signal.

The displacement device is designed to move the door leaf in an x-direction of the rail vehicle in order to move the door leaf between the closed position and an open position. The device for sealing can thus comprise further functions of the guide system or can itself represent the guide system.

The displacement device is designed as a passive component which is designed to move the door leaf in the z-direction using a movement of the door leaf in the x-direction.

The displacement device has at least one pivot lever which can be rotated about a pivot point and has a guide arm. The pivot point can preferably be coupled to a support roller unit which is linearly movable along a support rail that is straight at least in sections. The guide arm can, for example, be supported or can be supported on the guide path via a guide roller unit that is movable along a guide path. The pivot lever can have a fastening point for the door leaf.

According to the invention, the pivot lever has a first guide arm and a second guide arm. In this case, the first guide arm has a first fastening point at which a first support roller unit for guiding the first guide arm along a guide track is arranged. The second guide arm has a second fastening point, at which a second support roller unit for guiding the second guide arm along the guide track is arranged. The pivot point can be coupled to the door leaf and is arranged between the first fastening point and the second fastening point.

Under points such as the pivot point or the attachment points, for example also a position or point on the pivot lever or, for example, a through opening for receiving an axis or shaft, or the center point of such a through opening can also be understood. The arrangement of the pivot point between the attachment points can mean that the pivot point in the x direction, that is, parallel to the longitudinal axis of the vehicle, between the attachment points can be arranged, with an offset in the z-direction, that is, parallel to a vertical axis of the vehicle, can exist.

The guide track can have a straight guide surface and a gate. The backdrop can be angled with respect to the guide surface. A gate can serve as a guide element for the guide roller unit, for example. The guide roller unit can be steered onto a path curve outside of a plane of the guide surface through the coulisse.

The guide track can be formed by the support rail or a straight section of the support rail. The backdrop can be fixedly connected to the mounting rail. For example, the backdrop can be screwed on. The backdrop can be easily positioned and secured by screwing it on. For example, the backdrop can be a wedge placed on the mounting rail.

The guide track can be formed by the support rail. The guide surface and / or the link can be designed as a recess in the support rail. For example, the guide track and / or the backdrop can be milled into the support rail. The swivel arm can be precisely positioned by milling.

A transition from the guide surface to the gate can be arranged less than 200mm, for example also less than 120mm or less than 80 millimeters, in front of a closed position of the door leaf. Due to the short distance, a small grinding path can be achieved between the seals.

The first support roller unit can have a first support roller with a guide groove for guiding the first support roller along the straight guide surface. The second support roller unit can have at least one second support roller with a guide groove for guiding the second support roller unit along the straight guide surface and a link surface for guiding the second support roller unit along the link. The trajectory can be single-track or double-track. In the case of a double-track design, the link can be arranged parallel to a section of the straight guide surface. The first idler has none Link surface, the first support roller can be continued next to the link on the section of the linear guide surface mentioned, while the second support roller is guided due to its link surface on the link.

The attachment point can have a stroke of less than 15 millimeters. A small stroke is enough to separate the seals.

A load arm of the pivot lever between the pivot point and the attachment point can be shorter than the guide arm. Due to the middle position of the fastening point, a force on the support roller unit and the guide roller unit can be reduced.

The pivot point can be arranged between the attachment point and the guide arm. Due to the fastening point at the free end, the support roller unit can be loaded in the opposite direction to that of the guide roller unit. The guide arm at least partially encloses the rail.

The support rail can have a convex support profile. The support roller unit can have at least one support roller with a concave rolling profile. The support profile can be at least partially enclosed by the roll profile. Profiled rollers and rails result in good lateral guidance for the door leaf. This means that there is no need for an additional lateral guide.

The guide system can have a door leaf support which is rotatably mounted in the fastening point. The door leaf support can be connected to the pivot lever via a bracket. The position of the door leaf can be adjusted using a door leaf support.

The door leaf support can be rotatably mounted in a further pivot lever. The door leaf can be prevented from swinging by means of two swivel levers.

Furthermore, a rail vehicle with a device according to the approach presented here is presented, the mounting rail being oriented in the x-direction and the door leaf of a sliding door of the rail vehicle being connected to the attachment point of the pivot lever, the device being designed to position the door leaf in the area raise or lower the closed position.

In the following description of advantageous exemplary embodiments of the present invention, identical or similar reference numerals are used for the elements shown in the various figures and having a similar effect, a repeated description of these elements being dispensed with.

Fig. 1 shows a representation of a rail vehicle 100 with a sliding door 102 according to an embodiment. The sliding door 102 has a device 104 according to the approach presented here. The sliding door 102 here has a single door leaf 106. The door leaf 106 is movable in a vehicle height direction, that is to say upwards or downwards, using the device 104 for sealing. The vehicle height direction can be referred to as the z-direction.

The device 104 has at least one displacement device 112. The displacement device is designed to move the door leaf 106 in the area of a closed position of the sliding door 102 in the z-direction. In this case, a sealing element of the door leaf 106 is pressed against a counter-sealing element of a portal 107 of the rail vehicle 100. The door wing 106 can be raised or lowered for sealing.

The displacement device 112 can be an active component, that is to say an actuator such as a pneumatic cylinder or an electric motor. The displacement device 112 is then direct according to an exemplary embodiment driven to move the door leaf 106 in the z-direction. The sliding device 112 can be installed in the sliding door 102 at a later date. For example, the sliding door 102 can already have receptacles for the displacement device 112.

In one embodiment, the device 104 comprises a support rail 108 oriented in a longitudinal direction of the vehicle and a guide track 110 oriented essentially in the longitudinal direction of the vehicle. The displacement device 112 is designed as a pivot lever 112 and is movably supported on the support rail 108 and connected to the door leaf 106. The pivot lever 112 is supported on the guide track 110 at least near a closed position of the door leaf 106 in order to effect the vertical movement of the door leaf 106 via the pivot lever 112.

According to one exemplary embodiment, the support rail 108 is designed to be rectilinear overall. Alternatively, the support rail 108 can be designed to be straight in sections. According to one embodiment, the support rail 108 is designed to be straight, at least in a section that forms a guide track.

The device 104 can be referred to as a guide system 104 and is designed to lower the door leaf 106 during a closing movement of the sliding door 102 in the area of the closed position in order to bring sealing devices on an upper edge and a lower edge of the sliding door into contact. Conversely, when the door leaf 105 is opened in the area of the closed position, it is raised in order to separate the sealing devices.

According to the approach described here, sliding doors 102 can advantageously be very well sealable both in the upper and in the lower area. This does not require a sliding seal that is difficult to adjust. The sealing of the sliding doors 102 is required in order to improve the comfort for the passengers with regard to the sound insulation and the pressure tightness or also the thermal insulation for a low energy consumption.

In the approach presented here, the door leaf (TFL) 106 is raised or lowered. The raising or lowering can be referred to as a displacement in the z-direction. This function is basically independent of the drive system for the output of the door leaf 106 in the x-direction and for the locking of the door leaf 106.By raising or lowering, in addition to the rear edge and front edge or the finger protection rubber, a sealing surface is created in the upper and / or lower area of the door leaf 106 sealed. The top or bottom sealing is achieved by pressing a seal against a sealing surface or reducing the distance between two sealing surfaces. For example, the sealing surfaces can rest on one another, as a result of which the distance between the sealing surfaces is zero. In principle, the lifting of the door leaf 106 is carried out as close as possible to the closed position of the door leaf 106.

In one embodiment, the z-movement of the door leaf 106 is also carried out by active components such as servomotors, magnets or cylinders. In a further exemplary embodiment, the z movement of the door leaf 106 is achieved via the drive in the x direction that is already present for the sliding movement and suitable kinematics. Optimally, the lifting or lowering or the z-stroke of the sliding door only takes place when the closed position is reached, whereby a pure z-movement without additional x-movement and y-movement is achieved in order to minimize a sliding path of the seal at the top and bottom as far as possible. The lifting can take place, for example, by a lever system 112. The door leaf can be lowered accordingly as shown here.

In one embodiment, the rail vehicle 100 has a pivoting sliding door 102 which is raised or lowered in the z-direction by the device 104 in the closed position in order to seal the sealing elements.

Fig. 2 shows an illustration of a device 104 according to an embodiment. The device 104 corresponds essentially to the device in FIG Fig. 1 . In contrast to this, however, the device 104 is designed here to move the door leaf 106 when it is closed in the area of the closed position in the vehicle height direction, according to this exemplary embodiment to raise it. A pivot point 200 or a rotation axis 200 of the pivot lever 112 is rotatably mounted in a support roller unit 202. The support roller unit 202 here has a single support roller 204 which rolls on the support rail 108 during the opening movement and the closing movement in the longitudinal direction of the vehicle. The axis of rotation 200 corresponds to an axis of rotation of the support roller 204. The support roller unit 202 can also have several support rollers 204, the rotation axis 200 then running, for example, through a center of gravity of the support roller unit 202. The longitudinal direction of the vehicle can be referred to as the x-direction.

The pivot lever 112 has a guide arm 206 and a load arm 208. The door leaf 106 hangs from the load arm 208 via a bracket 210. In other words, the load arm 208 has a fastening point 212 for the door leaf 106. A guide roller unit 214 is arranged at one end of the guide arm 206. The guide arm 206 supports a torque resulting from the weight of the door leaf 106 on the guide track 110 via the guide roller unit 214. The guide roller unit 214 here has a single guide roller 216. The axis of rotation of the guide roller 216 is essentially parallel to the axis of rotation of the support roller 204. The guide roller unit 214 can also have a plurality of guide rollers 216.

The guide track 110 is formed here by a guide surface 218 of the support rail 108 and a link 220 screwed onto the support rail 108. The gate 220 forms a rolling surface for the guide roller 216 that is oriented obliquely to the guide surface 218. When the guide roller 216 rolls onto the link 220, the pivot lever 112 is rotated about its axis of rotation 200 and the door leaf 106 is raised.

In one embodiment, the guide track 110 is formed by the guide surface 218 and a recess in the support rail 108. The guide roller 216 then rolls from the guide surface 218 into the recess and the pivot lever 112 rotates in the opposite direction about the axis of rotation 200, the door leaf 106 being lowered.

The load arm 208 is aligned essentially horizontally here when the guide roller 216 rests on the guide surface 218. The guide arm 206 is angled with respect to the load arm 208 and points obliquely downwards. The load arm 208 is approximately half as long as the guide arm 206. This results in a lever ratio in which the guide roller 216 is pressed against the guide track 110 with approximately half the weight of the door leaf 106 bearing on the load arm 208. About one and a half times the weight is applied to the support roller 204.

In other words shows Fig. 2 a device 104 for lifting the sliding door 106. The device 104 is used, for example, in a sliding door entry system.

Fig. 3 shows a representation of a device 104 with a further pivot lever 112 according to an embodiment. The device 104 corresponds essentially to the device in FIG Fig. 2 . In addition, the device 104 has a further swivel lever 112, which is identical to the swivel lever 112 and rolls over a further support roller 204 approximately one door width of the door leaf 106 at a distance from the swivel lever 112 on the support rail 108. Here, the tab 210 extends essentially over the width of the door and is coupled to both pivot levers 112. The door wing 106 is screwed to the bracket 210. The further pivot lever 112 is pivoted in the area of the closed position via a further link 220 arranged on the support rail 108.

In other words shows Fig. 3 a mechanism 104 for lifting. With this concept, lowering in the closed position can also be implemented in principle.

For the optimization with regard to the lowest possible displacement force or drive force with the highest possible sealing stroke, that is to say the stroke of the door leaf 106 in the z-direction, parameters can be considered. At least a small amount of clearance is necessary in order to prevent the seal from grinding over the entire travel path or door stroke, that is to say the movement in the x direction. For example, the lever ratios can be taken into account based on the coordinate positions of the pivot point 200, the fastening point 212 and the guide point become. The weight of the door leaf 106 can also be taken into account. Furthermore, the sealing forces (N / mm) above and below and the sealing forces due to the seal on the rear edge and on the rubber finger protection can be taken into account. A parameter is also a maximum possible drive force and a minimum necessary stroke in the z-direction. An inclination of the gate 220 can also be taken into account. Another parameter is a sliding path of the transverse seals at the top and / or bottom. This should be minimal in order to minimize seal wear. A desired travel path in the x-direction shortly before the closed position can also be taken into account with a gate inclination of zero degrees. In this way it can be achieved that in the closed and locked position of the entry system no force is generated in the opening direction which would act against the lock. If the role in the gate 220 is at an angle greater than zero degrees, there is an automatic force component in the x-direction as a function of the weight of the door leaf 106 and the gate angle.

Raising the door leaf 106 also has the advantage that, in the event of an emergency actuation of the system 104, the door leaf 106 is pressed in the opening direction via the gate 220 with the help of the weight of the door leaf 106, and thus a certain gap can arise between the rubber finger guards.

Fig. 4 shows a sectional illustration of a device 104 according to an embodiment. The device 104 corresponds essentially to one of those in FIG Figures 1 to 3 devices shown. The support rail 108 and the guide track 110 are formed in one piece by a sheet metal profile. The support rail 108 here has a convex support profile, while the support roller 204 has a concave roll profile. As a result of the combination of the concave and convex profiles, the support roller 204 is guided in a vehicle lateral direction or a y-direction. The guide roller 216 and the guide track 110 have a flat profile.

Fig. 5 shows an illustration of a device 104 according to an embodiment. The device 104 corresponds essentially to the device in FIG Fig. 4 . Here the load arm 208 is aligned in line with the weight force. The load arm 208 thus hangs vertically downwards. The guide arm 206 is angled here and partially in the load arm 208 integrated. The lever arm of the guide arm 206 is approximately the same size as the load arm 208.

The guide surface 218 is designed here as a recess from the support rail 108. The inclined rolling surface is designed as the outlet of the recess. When the guide roller 216 is arranged in the region of the guide surface 218, it is essentially unloaded and can lose contact with the guide surface. When the guide roller 216 is arranged in the area of the inclined rolling surface, the load arm 208 with the door leaf 106 is deflected laterally upwards.

Fig. 6 shows an illustration of a lifting movement of a sliding door 102 according to an embodiment. The sliding door 102 is guided using a guide system according to the approach presented here. As a result of the guide system, the door leaf 106 of the sliding door 102 executes an essentially vertical movement in the area of the closed position. As a result of the movement, a sealing surface 600 is pressed against a sealing element 602 and a gap 604 between the door leaf 106 and a frame 606 of the sliding door 102 is sealed.

Here the sealing surface 600 is movable with the door leaf 106 and the sealing element 602 is arranged on the frame 606.

The door leaf 106 is guided here in the y-direction by a sliding strip 606. The sliding strip 606 is arranged in a pocket and is also movable in the z-direction in the pocket. A step strip profile 608 is arranged on an outside of the sliding door 102. The door leaf 106 runs in a slot between the tread profile 608 and a floor of the rail vehicle 100.

The sealing surface 600 is formed by a lower transverse profile 610 of the door leaf 106. A molded part 612 is also arranged as a sealing profile on a rear edge of the door leaf.

In other words shows Fig. 6 an example of a sealing of the door leaf 106 below. The door leaf 106 is once in the open position and once in shown in the closed position for the concept of lifting the door leaf 106. The bottom seal 602 is on the portal side, that is, not on the door leaf 106. Conversely, the seal 602 can also be arranged on the door leaf 106. The sealing surface 600 is located on the door leaf 106. The lower guide 606 is of conventional design here, with sufficient overlap of the guide system 606 still being present despite the stroke in the z-direction.

Fig. 7 shows a representation of a sealing element 700 for a sliding door 102 according to an embodiment. The sealing element 700 is arranged on a rear edge of the door leaf 106 and is movable with the door leaf 106 in the x direction. The sealing element 700 seals against a sealing surface 702 which is arranged on a portal 107 of the sliding door 102. The sealing surface 702 is formed by a sealing angle. The sealing element 700 is designed as a deformable lip.

In other words shows Fig. 7 an example of sealing a rear edge of a door leaf. The seal 700 can again be attached on the portal side or on the door leaf side. Appropriate molded parts can be used for the transitions to the transverse seals above and below in order to minimize the leakage area in the transition.

Fig. 8 shows a detailed representation of a rail vehicle 100 with a device 104 according to an embodiment. The device 104 corresponds essentially to one of the devices in FIG Figures 1 to 5 . The device 104 is integrated into a portal 107 of the rail vehicle 100. The support rail 108 is firmly connected to the portal 107. The pivot lever 112 is guided on the support rail 108 and connected to the door leaf 106. An upper sealing surface 800 is arranged on the door leaf 106, while an upper sealing element 802 is arranged on the portal 107. As a result of the vertical movement of the door leaf 106 in the area of the closed position, the sealing surface 800 is pressed against the sealing element 802 and seals the gap between the door leaf 106 and the portal 107.

The upper sealing surface 800 is part of an upper transverse profile of the door leaf 106 here.

In other words shows Fig. 8 an example of a seal on the door wing 106 at the top. The open position is shown. The seal 802 is designed on the portal side and the sealing surface 800 is located on the door leaf 106.

The seal 802 itself can be attached to the portal 107 of the vehicle 100 as a complete circumferential sealing frame. This results in a very good transition between longitudinal and transverse seals and at the transition between door leaves. The door wing 106 is the sealing surface 800 and does not require a seat for seals except for the finger protection rubbers.

If such a solution is not possible, the seals 802 can be attached to the door leaf 106, the sealing surfaces 800 then being attached to the portal 107. By lifting the door seals 802, the seals or molded parts at the transitions between longitudinal and transverse seals can be designed in such a way that there is no leakage area in the closed position.

Fig. 9 shows a representation of a sealing element 602 for a sliding door 102 according to an embodiment. The sealing element 602 can, for example, instead of the sealing element in FIG Fig. 6 be used. Here the sealing element 602 is attached to the door leaf 106. The sealing surface 600 is fixed to the vehicle. The sealing element 602 is as in FIG Fig. 7 designed as a deformable lip. When the door leaf is raised via the guide system, the sealing element 602 touches the sealing surface 600 and seals the slot in the floor.

Fig. 10 shows an illustration of a device 104 according to an embodiment. The device 104 corresponds essentially to the device in FIG Figures 2 and 3 . In contrast to this, the pivot lever 112 has an upwardly directed extension 1000 which has the pivot point 200. The pivot point 200 here coincides with a pivot point of the support roller 204. A center of gravity of the pivot lever 112 is arranged below the pivot point 200, whereby the pivot lever 112 a has high inherent stability. The fastening point 212 is arranged here essentially at the same level as the guide roller 216.

The gate 220 is fixedly connected to the support rail 108. For example, the gate 220 is welded or glued to the mounting rail 108. The gate 220 has the incline 1002 aligned obliquely to the guide surface 218 and a latching surface 1004 aligned parallel to the guide surface 218. The guide roller 216 is arranged on the latching surface 1004 in the closed position. From the beginning of the slope 1002 up to the closed position, the gate 220 has a length of less than 80 millimeters.

During a closing movement, the guide roller 216 rolls down over the slope 1002. This raises the attachment point 212 on the opposite side of the pivot point 200. The attachment point 212 is raised less than 15 millimeters.

Fig. 11 shows an illustration of a coupled device 104 according to an embodiment. The device 104 corresponds essentially to the device in FIG Fig. 10 . In contrast to this, the pivot point 200 lies essentially on a connecting line between the fastening point 212 and the guide roller 216. The pivot point 200 is rotatably mounted in a coupling member 1100. The coupling member 1100 couples the fulcrum 200 to the support roller unit 202. By means of the coupling member 1100, a trajectory of the fastening point 212 is oriented essentially transversely to the support rail 108.

Fig. 12 shows a flowchart of a method 1200 for sealing a door leaf for a rail vehicle, wherein the door leaf is moved in a step 1204 of moving in the area of a closed position of the door leaf using a displacement device in a z-direction of the rail vehicle to a sealing element of the door leaf against a To press counter-sealing element of a portal of the rail vehicle. According to one exemplary embodiment, step 1204 is carried out independently of a further closing movement of the door leaf.

According to a further exemplary embodiment, step 1204 is carried out together or in combination with a further closing movement of the door leaf. For this purpose, the method 1200 also has, for example, a step 1202 of guiding, in which the door leaf of the sliding door is guided from an open position in a closing direction into a region of a closed position using a guiding system according to the approach presented here.

Fig. 13 shows a representation of a device 104 for sealing at least one door leaf 106 for a vehicle according to an embodiment. This can be, for example, a vehicle, as it is based on Fig. 1 is described. The device 104 comprises a pivot lever 1350 with a first guide arm 1351 and a second guide arm 1352. The pivot lever 1350 is, for example, U-shaped or V-shaped. The guide arms 1351, 1352 form legs of the pivot lever 1350. In a connection area of the guide arms 1351, 1352, the pivot lever 1350 has a pivot point 200, via which the pivot lever 1350 can be pivotably connected to a door leaf 106 and in which FIG Fig. 13 illustration shown is connected. According to this exemplary embodiment, the pivot lever 1350 points in the area of the pivot point 200 a round opening. For example, an axis or shaft coupled to the door leaf 106 can be guided through the through opening.

The first guide arm 1351 has a first fastening point 1355 at its free end and the second guide arm 1352 has a second fastening point 1356 at its free end. According to this exemplary embodiment, the guide arms 1351, 1352 each have a through opening in the area of the fastening points 1355, 1356, for example for receiving a shaft or axle. According to the embodiment shown, a first support roller 1360 of a first support roller unit 1361 is attached to the first guide arm 1351 at the first attachment point 1355 and at least one second support roller 1363 of a second support roller unit 1364 is attached to the second guide arm 1352 at the second attachment point 1356. In addition to the support rollers 1360, 1363, the support roller units 1361, 1364 can, for example, also include axes for fastening the support rollers 1360, 1363 to the fastening points 1355, 1356.

According to one embodiment, the pivot lever 1350 is designed as a flat plate extending in the xz plane. Alternatively, the pivot lever 1350 can also have at least one kink. The fastening points 1355, 1356 are arranged offset from one another in the x direction. The pivot point 200 is arranged between the fastening points 1355, 1356 with respect to the x-direction. If the guide arms 1351, 1352 - deviating from the one in Fig. 13 embodiment shown - run parallel to one another, the pivot point 200 can be arranged on a connecting line connecting the fastening points 1355, 1356. When the guide arms 1351, 1352, as in Fig. 13 are angled to one another, the pivot point can be arranged offset in the z direction, here for example in the direction of a lower edge of the door leaf 106, relative to the fastening points 1355, 1356.

From the vehicle or a door portal of the vehicle, in Fig. 13 a support rail 108 with a guide surface 218 and a gate 220 is shown. The guide surface 218 represents a path running in the x direction. The support rollers 1360, 1363 are shaped so that they can roll along the guide surface 218. The backdrop is 220 In accordance with this exemplary embodiment, it is formed as a plate-shaped element which is fastened to the support rail 108. An edge of the gate 220 is formed as a slope 1002 aligned obliquely to the guide surface 218 and a latching surface 1004 adjoining the slope 1002 and aligned parallel to the guide surface 218. The slope 1002 begins at the level of the guide surface 218. According to this exemplary embodiment, the second support roller unit 1364 has a single second support roller 1363, which is shaped so as not to continue on the guide surface 218 at the level of the gate 220 but on the slope 1002 and the latching surface 1004 to roll. Thus, the guide surface 218, together with the bevel 1002 and the latching surface 1004, forms a guide track for guiding the support rollers 1360, 1363 during a closing movement and an opening movement of the door leaf 106 Section of the guideway.

According to one embodiment, a distance in the x direction between the first fastening point 1355 and the pivot point 200 is the value a and a distance in the x direction between the second fastening point 1356 and the pivot point 200 is the value b. The value a is, for example, greater, for example at least twice as large as the value b. In the position of the device 104 shown, a force F1 acts at the first fastening point 1355, a force F2 acts at the second fastening point 1356, and a force F3 acts downwards at the pivot point 200.

The door leaf weight F3, at the connection point to the door leaf 106, is located between the first support roller 1360 (force F1) and the second support roller 1363. The second support roller 1363 moves in the closed position of the door leaf 106 onto a gate 220 shaped as a wedge. According to this exemplary embodiment, the first support roller 1360 moves exclusively on the guide surface 218, which is shaped as a running surface. The second support roller 1363 basically also rolls on the guide surface 218, but just before the closed position it hits the slope 1002 of the gate 220 and thereby controls the height movement of the door leaf 106.

The pair of rollers, consisting of the support rollers 1360, 1363, is designed for each door leaf 106 at least on the front edge and the rear edge of the door leaf 106. Thus, according to an exemplary embodiment, the device 104 has a further pivot lever with further support rollers and a further link. In order to integrate this arrangement as space-saving as possible, based on the space requirement in the longitudinal direction (x-direction) with regard to the required rail length of the support rail 108, a certain overlap is possible. Such an overlap enables the second support roller on the front edge to move as far as the link 220 of the second support roller 1363 on the rear edge of the door leaf 106, as shown in FIG Fig. 14 can be seen.

The advantage of in the Figures 13 and 14th The illustrated embodiments consists in the fact that the force F3, that is to say the weight force of the door leaf 106, is divided between the two support rollers 1360, 1363, also referred to as running rollers. In this way it can be avoided that the load on the first support roller 1360 is higher than the load which is caused by the door leaf 106 and corresponds to the force F3 acting on the pivot point 200.
