SWING SLIDING DOOR SYSTEM

Description

AREA OF INVENTION

[0001] The present invention relates to a pivot-sliding door system for a vehicle, in particular a rail vehicle, comprising a door leaf extending in a plane, which can be moved from a closed position to a release position and vice versa by means of a pivot mechanism, wherein the closed position and the release position are spaced apart from each other in a first direction which is normal to the plane of the door leaf and points from the closed position to the release position, wherein the door leaf in the release position is displaceable parallel to a second direction normal to the first direction, and wherein the pivot mechanism comprises a pivot column which extends along a third direction normal to the first direction and to the second direction and is rotatable about a first axis of rotation which is parallel to the third direction, wherein the pivot mechanism further comprises a pivot arm and a drive system for the pivot arm.wherein the swivel arm is rotatably mounted on the pivot column about it and is in operative contact with the door leaf via an end area, and wherein the drive system is provided for rotating the swivel arm about the pivot column in order to cause the movement of the door leaf from the closed position to the released position and vice versa. STATE OF THE ART

[0002] Swing-sliding door systems for vehicles, particularly rail vehicles, are known from the prior art, in which a door leaf can be moved back and forth between a closed position and a released position by means of a pivoting mechanism comprising a rotating column. The door leaf can also be referred to as a door wing and is the movable part of a door.

[0003] In the release position, each door leaf can be moved parallel to a sliding direction. The back-and-forth movement between the closed and release positions is also called the opening movement and occurs perpendicular to the sliding direction.

[0004] A disadvantage of the aforementioned solution, according to the state of the art, is that pressure surges on the door leaf are transmitted directly into the pivot column. Such pressure surges can arise, for example, from sudden air pressure differences between the interior and exterior of a car body, which can occur when entering or exiting tunnels, or from outward or inward impacts on the door leaf by people. To prevent mechanical damage to the pivot column, it must be dimensioned accordingly, which entails a high material and space requirement.

[0005] From EP 0312450 A1, a swing-sliding door with a fixed frame for trains is known, which has a door leaf that extends in a closing plane in a closed position and can be moved into an open position by means of a pivoting mechanism. Interlocking means are provided to secure the door leaf against lateral forces in the closed position. The pivoting mechanism comprises a shaft which couples rotatable elements together. A tube is rotatably arranged around the shaft, to which links are rigidly connected, which in turn are pivotally connected to slides to establish an operative connection with the door leaf.

[0006] From DE 202016101709 U1, a swing-sliding door with a pivot column to which a pivot lever is directly attached is known. A seal is provided at a lower edge of the swing-sliding door, which can be folded in by a folding device, the folding device being controlled by the rotational movement of the pivot column. TASK OF INVENTION

[0007] It is therefore an object of the present invention to provide a pivot-sliding door system that avoids the disadvantages described above. In particular, the pivot-sliding door system should be able to absorb pressure surges while simultaneously allowing for material- and space-saving dimensions of the pivot column. PRESENTATION OF THE INVENTION

[0008] To solve the described problem, a swing-sliding door system for a vehicle, in particular a rail vehicle, comprising a door leaf extending in a plane, which can be moved from a closed position to a released position and vice versa by means of a pivoting mechanism, wherein the closed position and the released position are spaced apart from each other in a first direction which is normal to the plane of the door leaf and points from the closed position to the released position, wherein the door leaf in the released position is displaceable parallel to a second direction normal to the first direction, and wherein the pivoting mechanism comprises a pivot column which extends along a third direction normal to the first direction and to the second direction and is rotatable about a first axis of rotation which is parallel to the third direction.wherein the pivoting mechanism further comprises a pivoting arm and a drive system for the pivoting arm, wherein the pivoting arm is rotatably mounted on the pivot column about it and is in operative connection with the door leaf via an end region, and wherein the drive system is provided for rotating the pivoting arm about the pivot column in order to cause the movement of the door leaf from the closed position to the released position and vice versa, according to the invention provided that the pivoting arm has a guide track and the drive system has a locking bolt guided in the guide track in order to be able to transmit drive movements from the drive system to the pivoting arm and pressure impulses from the door leaf to the drive system.

[0009] Of course, the swing-sliding door system can also include several, especially two, door leaves, or the swing-sliding door system can have one or more additional door leaves besides the door leaf.

[0010] The plane of the door leaf is spanned by the second and third directions.

[0011] According to the above, the positions of the door leaf in the closed position and the released position have a distance to each other that is measured in the first direction.

[0012] The aforementioned movement of the door leaf parallel to the second direction is to be understood as a back-and-forth movement and consequently also includes – in the mathematical sense – a movement antiparallel to the second direction. The second direction could also be referred to as the sliding direction or longitudinal direction, and the first direction as the transverse direction.

[0013] Because the pivot arm is mounted on the pivot column so that it can rotate around it, the pivot arm cannot be directly rotated by the pivot column. Instead, the drive system causes the pivot arm to rotate around the pivot column, thus moving the door leaf from the closed position to the open position and vice versa. Due to this decoupling of the pivot arm and pivot column, pressure surges on the door leaf, or reaction forces, are transmitted directly from the door leaf to the pivot arm—due to the direct connection between the door leaf and the pivot arm—but not directly from the pivot arm to the pivot column. Instead, the reaction forces act directly on the drive system, which can conveniently be designed to be as stable as necessary. A resulting reaction torque on the pivot column can therefore be kept comparatively small or even avoided altogether.The mechanical stress on the pivot column during pressure surges on the door leaf is drastically reduced compared to prior art solutions, particularly the prior art described above. Consequently, the pivot column can be designed to be very slim without increasing the risk of damage from pressure surges on the door leaf, thus saving material, space, and costs.

[0014] The relevant pressure pulses act outwards in the closed position, i.e., parallel or at least with a directional component parallel to the first direction, and in the released position inwards, i.e., antiparallel or at least with a directional component antiparallel to the first direction.

[0015] As mentioned, the swing-sliding door system according to the invention is designed so that the swing arm has a guide track and the drive system has a locking bolt guided in the guide track, in order to transmit drive movements from the drive system to the swing arm and pressure impulses from the door leaf to the drive system. The kinematics of the swing arm can therefore be adjusted very conveniently as desired by appropriately designing the guide track, whereby the movement of the swing arm is accompanied by the movement of the locking bolt, and the movement of the locking bolt, due to the guide track, results in the desired movement of the swing arm.

[0016] The locking bolt can slide along the guide track, and rolling would also be conceivable if the locking bolt were rotatably mounted, particularly around its longitudinal axis. Clearly, a certain amount of play in the locking bolt within the guide track is essential; otherwise, its movement would be blocked. Viewed from a third perspective, the guided movement of the locking bolt within the guide track therefore results in a contact point between the locking bolt and the guide track, with a contact line extending in this third direction due to the spatial extent.

[0017] In order to enable the locking bolt to be moved in a simple, mechanically stable and precise manner, a particularly preferred embodiment of the swing-sliding door system according to the invention provides that the drive system comprises a locking disc piece to which the locking bolt is attached projecting along the third direction, wherein the locking disc piece is rotatably mounted about a second axis of rotation running parallel to the first axis of rotation and engages with a rotary disc piece, wherein the rotary disc piece is non-rotatably connected to the pivot column.

[0018] As the term "piece" already implies, the locking disc piece and / or the rotating disc piece do not have to have a complete disc or cylinder shape and in particular do not have to be rotationally symmetrical, although such designs are of course not excluded.

[0019] When the pivot column rotates, the rotating disc is also rotated, and—due to the engagement of the locking disc with the rotating disc—this in turn rotates the locking disc. The rotation of the locking disc is accompanied by the movement of the locking bolt along a circular arc, which moves the pivot arm according to the guide track. Since the end of the pivot arm is in operative contact with the door leaf, the pivot arm, as it moves, moves the door leaf from the closed position to the unlocked position and vice versa.

[0020] The engagement of the locking disc element with the rotating disc element can be achieved in any desired manner, for example by frictional engagement. To guarantee a particularly precise and reliable transmission of motion between the locking disc element and the rotating disc element, a particularly preferred embodiment of the inventive swing-sliding door system provides that the rotating disc element and the locking disc element have toothed sections that engage with each other.

[0021] In a particularly preferred embodiment of the swing-sliding door system according to the invention, the locking bolt is arranged in the closed position either in front of or behind the second axis of rotation when viewed in the first direction. This arrangement, whether in front of or behind the second axis of rotation, depends on the specific design of the guide track and the specific direction of rotation of the locking disc element – ​​and thus ultimately on the direction of rotation of the rotating disc element or the pivot column. This arrangement ensures that the reaction forces resulting from outward-directed pressure surges on the door leaf – i.e., those parallel to the first direction or with a directional component parallel to the first direction – are transferred to the second axis of rotation.The reaction forces are favored in the locking disc section in the region of the second axis of rotation, whereby the reaction forces – depending on the specific arrangement mentioned above – can be parallel to the first direction or only form a small angle with the first direction. Accordingly, a reaction moment on the first axis of rotation, or on the rotating disc section and thus on the rotating column, can be minimized or completely avoided.

[0022] To minimize these reaction forces, the locking bolt can be arranged in the closed position such that, viewed in the first direction, its longitudinal axis is positioned as close as possible to the second axis of rotation, even though the locking bolt and the second axis of rotation are spaced apart from each other in the first direction. Accordingly, in a particularly preferred embodiment of the inventive swing-sliding door system, the locking bolt overlaps the second axis of rotation in the closed position when viewed in the first direction. That is, viewed in the first direction, the second axis of rotation lies partially within the outline of the locking bolt. This makes it possible to transfer the entire reaction force, or almost the entire reaction force, to the drive system.to transfer to the locking disc piece in the area of ​​the second axis of rotation and to keep the reaction moment on the first axis of rotation or on the rotating disc piece (and thus on the rotating column) to a minimum or to avoid it entirely.

[0023] In order to completely transfer the reaction forces from outward pressure surges acting on the door leaf in the closed position into the second axis of rotation, and thus completely avoid a reaction torque on the first axis of rotation or on the pivot element (and thus on the pivot column), a particularly preferred embodiment of the inventive swing-sliding door system provides that, viewed in the first direction, the locking bolt is arranged in front of the second axis of rotation in the closed position, and that a longitudinal axis of the locking bolt overlaps with the second axis of rotation in the closed position. That is, the longitudinal axis of the locking bolt and the second axis of rotation are aligned one above the other when viewed in the first direction. Nevertheless, the longitudinal axis of the locking bolt and the second axis of rotation are spaced apart from each other in the first direction.

[0024] In principle, such an overlapping arrangement of the longitudinal axis of the locking bolt and the second pivot axis would also be conceivable if the locking bolt, when the door leaf is closed (viewed in the first direction), is located behind the second pivot axis. As already mentioned, this depends on the specific design of the guide track and the specific direction of rotation of the locking disc. The arrangement of the locking bolt (viewed in the first direction) in front of the second pivot axis can prove advantageous insofar as this arrangement is on the side of the second pivot axis facing away from the door leaf, which is comparatively less problematic with regard to the space available when the door leaf is closed.

[0025] The shape or geometry of the guide track can influence the force required to unlock or move the door from the closed position to the released position, or even ensure that such a movement is possible at all. Accordingly, in a particularly preferred embodiment of the inventive swing-sliding door system, a tangent to the contour of the guide track, viewed in the third direction, runs at an angle to the second direction at a point of contact with the locking bolt when the door is in the closed position. That is, this tangent does not run parallel to the second direction – the angle is clearly greater than zero – thus ensuring that unlocking or moving the door from the closed position to the released position is possible without difficulty.

[0026] By appropriate design, in particular by choosing a suitable angle, the force required can be sufficiently limited or it can be ensured that this force is not too great.

[0027] The contact point or contact line extending in the third direction is located where the locking bolt and the guide track make contact when unlocking or moving the door from the closed to the released position. This is typically on the contour of the guide track opposite the contact point or contact line that forms (without pressure surges or other outward-directed forces acting on the door leaf) when the door leaf has been moved from the released to the closed position. The above applies to both contact point / contact line positions.

[0028] Alternatively or additionally, to ensure the possibility of trouble-free unlocking or transitioning from the closed position to the release position in a particularly preferred embodiment of the swing-sliding door system according to the invention, in which the longitudinal axis of the locking bolt and the second axis of rotation do not overlap in the closed position, it is provided that, viewed in the first direction, the locking bolt is arranged in front of the second axis of rotation in the closed position, and viewed in the third direction, a first angle between the first direction and an imaginary connecting line between a longitudinal axis of the locking bolt and the second axis of rotation is between 0.1° and 5°.

[0029] The specified angle range reliably ensures the possibility of unlocking or transitioning from the closed to the released position. Furthermore, the required force can be influenced by selecting the appropriate angle, with larger angles requiring less force. At the same time, it is ensured that the required force is not too low, thus preventing accidental unlocking or transition from the closed to the released position.

[0030] Here too, an analogous design would be conceivable in principle, in which the locking bolt is located behind the second axis of rotation, which, as already mentioned, depends on the specific design of the guide cam and the specific direction of rotation of the locking disc piece.

[0031] The shape or geometry of the guide track can be designed in different ways to ensure the functionality described above. To ensure a simple geometry of the guide track and thus simple manufacturing, a particularly preferred embodiment of the swing-sliding door system according to the invention provides that, in the closed position, the locking bolt is arranged at least partially in a first end region of the guide track, and that, viewed in the first direction, the first end region is located in front of the second axis of rotation and overlaps with it. Furthermore, in the released position, the locking bolt is arranged at least partially in a second end region of the guide track, and that, viewed in the first direction, the second end region is located between the first axis of rotation and the second axis of rotation, and that the first end region is located behind the second axis of rotation and overlaps with it.wherein the first end region of the guidance backdrop extends away from a first end of a course of the guidance backdrop and the second end region of the guidance backdrop extends away from a second end of the course of the guidance backdrop and the two end regions of the guidance backdrop each comprise at least 5%, preferably at least 10%, particularly preferably at least 20%, of the course of the guidance backdrop.

[0032] Alternatively or additionally, in order to ensure a simple geometry of the guide track and thus simple manufacturing, a particularly preferred embodiment of the inventive swing-sliding door system provides that in the release position the guide track has a concave curvature at least partially relative to the second axis of rotation, and preferably the curvature is only concave.

[0033] More generally, to ensure a simple geometry of the guide track exhibiting the desired functionality and thus simple manufacturing, it may be provided that the guide track has a profile that is curved at least in sections and / or has at least one kink.

[0034] In a particularly preferred embodiment of the swing-sliding door system according to the invention, it is provided that, viewed in the third direction, in the release position, a second angle between a normal to the contour of the guide track at a contact point with the locking bolt and an imaginary connecting line between the contact point and the second axis of rotation is greater than 0°, preferably greater than 30°. This prevents blockage in the release position, thereby enabling, in principle, the closing of the door leaf, particularly manually, or its transition from the release position to the closed position.

[0035] The contact point or contact line extending in the third direction is located where the locking bolt and the guide track make contact when the door is pulled closed, i.e., when the door leaf is pulled / moved inwards or against the first direction. This is usually on the contour of the guide track opposite the contact point or contact line that is established (without pressure surges or other inwards force acting on the door leaf) when the door leaf has been moved from the closed position to the unlocked position. The above applies to both contact point / contact line positions.

[0036] To achieve a simple, stable, and cost-effective connection between the end of the pivot arm and the door leaf, a preferred embodiment of the pivot-sliding door system according to the invention provides for a guide roller in the end of the pivot arm. This guide roller is rotatable about a third axis of rotation, which is parallel to the third direction. The guide roller engages with a longitudinal guide running parallel to the second direction and rigidly connected to the door leaf. The longitudinal guide can be integrated into the door leaf, particularly such that it does not protrude from the inside of the door leaf in the first direction.

[0037] Analogous to the above, the invention provides a system comprising a car body and at least one swing-sliding door system according to the invention, wherein the drive system, in particular a locking disc component of the drive system, is supported on the car body, preferably via a bracket. This support is particularly suitable for absorbing pressure surges acting on the door leaf. One or more swing-sliding door systems according to the invention can be provided on the car body.

[0040] Fig. 1 Figure 1 shows a pivot-sliding door system 1 according to the invention on a car body 34, such as rail vehicles may have, with the view pointing towards an inside of a vehicle wall 22 formed by the car body 34. The pivot-sliding door system 1 according to the invention and the car body 34 form a system according to the invention or at least a part of such a system.

[0041] The pivot-sliding door system 1 comprises a unit that moves in one plane, which is in Fig. 1 door leaf 2, which coincides with the drawing plane, can be moved from one side to the other by means of a pivoting mechanism. Fig. 1 The closed position 3 shown changes to a release position 4 - see below. Fig. 4 , Fig. 6 and Fig. 10 - and vice versa. The closed position 3 and the release position 4 are spaced apart from each other in a first direction 5, which is normal to the plane of the door leaf 2 and points from the closed position 3 to the release position 4, wherein the door leaf 2 in the release position 4 can be moved parallel to a second direction 6 normal to the first direction 5 in order to release a door opening in the first direction 5, so that persons can enter and exit the car body 34 through the door opening.

[0042] The pivoting mechanism comprises a rotating column 8 which runs along a third direction 7 perpendicular to the first direction 5 and to the second direction 6 and is rotatable about a first axis of rotation 9 which is parallel to the third direction 7.

[0043] The pivoting mechanism further comprises a pivoting arm 10 and a drive system 25 for the pivoting arm 10, wherein, in the illustrated embodiment, the drive system 25 is supported on a bracket 30 of the car body 34 or via the bracket 30 on the car body 34. The pivoting arm 10 is rotatably mounted on the pivot column 8 and is operatively connected to the door leaf 2 via an end section 29. The drive system 25 is designed to rotate the pivoting arm 10 about the pivot column 8 in order to initiate or accomplish the movement of the door leaf 2 from the closed position 3 to the open position 4 and vice versa.

[0044] In the illustrated embodiment, the pivot arm 10 has a guide track 15, and the drive system 25 has a locking bolt 14 guided in the guide track 15, in order to transmit drive movements from the drive system 25 to the pivot arm 10 and pressure surges associated with an acting force 23 from the door leaf 2 to the drive system 25. The locking bolt 14 is necessarily guided with a certain amount of play in the guide track 15; otherwise, movement of the locking bolt 14 in the guide track 15 would be blocked.

[0045] The swivel arm 10 with the guide track 15 and the locking bolt 14 are, for example, in Fig. 2, Fig. 3 und Fig. 4 recognizable, whereby the door leaf 2 is in Fig. 2 in closed position 3, in Fig. 5 in release position 4 and in Fig. 4 in an intermediate position 32 - of which there are mathematically infinitely many - which is occupied by the door leaf 2 on the way between the closed position 3 and the release position 4 (and vice versa).

[0046] In the illustrated embodiment, the drive system 25 further comprises a locking disc piece 11, to which the locking bolt 14 is attached projecting along the third direction 7, the locking disc piece 11 being rotatably mounted about a second axis of rotation 12 running parallel to the first axis of rotation 9 and engaging with a rotary disc piece 13, the rotary disc piece 13 being non-rotatably connected to the rotating column 8. In the illustrated embodiment, the rotary disc piece 13 and the locking disc piece 11 engage with each other via toothed sections, as shown in the schematic diagrams of Fig. 7 , Fig. 9 and Fig. 10 is clearly visible.

[0047] The aforementioned functional connection between the pivot arm 10 and the door leaf 2 is realized in the illustrated embodiment such that a guide roller 16 is arranged in the end region 29 of the pivot arm 10, which is rotatable about a third axis of rotation 17, wherein the third axis of rotation 17 is parallel to the third direction 7, wherein the guide roller 16 is in engagement with a longitudinal guide 18 running parallel to the second direction 6 and fixedly connected to the door leaf 2, cf. in particular Fig. 5 and Fig. 6 In addition to moving the door leaf 2 from the closed position 3 to the release position 4 and vice versa, the longitudinal guide 18 extending parallel to the second direction 6, in conjunction with the guide roller 16, also enables the door leaf 2 in the release position 4 to be moved back and forth antiparallel and parallel to the second direction 6.

[0048] In order to introduce, as completely as possible, a reaction force 24, which is caused by a pressure impulse on the door leaf 2 with the force 23 directed outwards or parallel to the first direction 5 or at least has a directional component parallel to the first direction 5, into the second axis of rotation 12 or into the locking disc piece 11 in the region of the second axis of rotation 12, in the illustrated embodiment, the locking bolt 14 is arranged in front of the second axis of rotation 12 when viewed in the first direction 5, with the locking bolt 14 overlapping the second axis of rotation 12 in the closed position 3. A reaction moment 33 (cf. Fig. 9 and Fig. 10 ) onto the turntable piece 13 and thus onto the rotating column 8 can therefore be largely ruled out and is therefore in Fig. 7 not available either.

[0049] To ensure that unlocking or transition from the closed position 3 to the release position 4 is possible, the guide track 15 is designed accordingly in the illustrated embodiment. Specifically, it is provided that, viewed in the third direction 7, in the closed position 3, a tangent t to the contour of the guide track 15 runs at a contact point 31 with the locking bolt 14 at an angle to the second direction 6, cf. Fig. 7 This angle is greater than zero. The contact point 31, or a contact line extending in the third direction 7, is located where the locking bolt 14 and the guide track 15 make contact when unlocking is performed. This is on the contour of the guide track 15 opposite the contact point or contact line that is established (without pressure surges or other outward-directed force acting on the door leaf 2) when the door leaf 2 has been moved from the release position 4 to the closed position 3. The above applies in any case, i.e., to both contact point / contact line positions.

[0050] Furthermore, in the illustrated embodiment, the guide track 15 is designed such that, viewed in the first direction 5, the locking bolt 14 is arranged in the closed position 3 in front of the second axis of rotation 12, and viewed in the third direction 7, a first angle α between the first direction 5 and an imaginary connecting line between a longitudinal axis 19 of the locking bolt 14 and the second axis of rotation 12 is between 0.1° and 5°, cf. the dashed lines in Fig. 7 The specified angular range reliably ensures the possibility of unlocking. Furthermore, the force required for unlocking can be influenced by selecting the first angle α, with larger angle values ​​corresponding to less force being required. At the same time, it is ensured that the required force is not too low, thus preventing accidental unlocking.

[0051] To ensure a simple geometry of the guide track and thus simple manufacturing, in the illustrated embodiment, the locking bolt 14 is arranged at least partially in a first end region 20 of the guide track 15 in the closed position 3, and the first end region 20 is arranged in front of the second axis of rotation 12 when viewed in the first direction 5 and overlaps with it, cf. Fig. 8 iVm Fig. 7 Furthermore, in the release position 4, the locking bolt 14 is at least partially arranged in a second end region 21 of the guide track 15, and viewed in the first direction 5, the second end region 21 is arranged between the first axis of rotation 9 and the second axis of rotation 12, wherein the first end region 20 is arranged behind the second axis of rotation 12 and overlaps with it, cf. Fig. 8 iVm Fig. 10 The first end area 20 of the guidance backdrop 15 extends away from a first end 27 of a course 26 of the guidance backdrop 15, and the second end area 21 of the guidance backdrop 15 extends away from a second end 28 of the course 26 of the guidance backdrop 15, wherein the two end areas 20, 21 of the guidance backdrop 15 each comprise at least 5%, preferably at least 10%, particularly preferably at least 20%, of the course 26 of the guidance backdrop 15, cf. Fig. 8 .

[0052] As from Fig. 10 As can be seen, the course 26 of the guide cam 15 in the release position 4 relative to the second axis of rotation 12 exhibits a concave curvature at least in sections.

[0053] To prevent a blockage in the release position 4 and to allow the door leaf 2 to be closed, particularly manually, the illustrated embodiment provides that, viewed in the third direction 7 in the release position 4, a second angle β between a normal to the contour of the guide track 15 at the contact point 31 with the locking bolt 14 and an imaginary connecting line between the contact point 31 and the second axis of rotation 12 is >0°, preferably >30°, cf. Fig. 10 .

[0054] The contact point or contact line extending in the third direction is located where the locking bolt and the guide track make contact when the door is pulled closed, i.e., when the door leaf 2 is pulled / moved inwards or against the first direction 5. This is typically on the contour of the guide track 15 opposite the contact point or contact line that is established (without pressure surges or other inwards acting on the door leaf 2) when the door leaf has been moved from the closed position to the released position. The above applies to both contact point / contact line positions.

[0055] Accordingly, an inwardly directed force 23 acting on the door leaf 2 results in a reaction force 24 acting at the contact point 31, which in turn causes a non-zero – albeit not particularly large – reaction torque 33 on the turntable piece 13 or the rotating column 8. This is the case both in the release position 4, cf. Fig. 10 , as well as in the intermediate position 32, cf. Fig. 9 . BEZUGSZEICHENLISTE
