wobei der Schwenkmechanismus

The invention relates to a pivoting sliding door for closing a passage opening in a vehicle wall

• at least one door leaf and
• at least one pivoting mechanism for moving the door leaf between a pivoted-in position and a pivoted-out position along a pivoting path,

where the pivot mechanism

• a support frame provided in a direction of passage for movable storage, which support frame has a support plate connected to the door leaf and a locking shaft, and
• comprises a support bracket permanently provided for connection to a vehicle wall.

STATE OF THE ART

Generic pivoting sliding doors for closing a passage opening in a vehicle wall, which pivoting sliding doors are pushed in front of a passage opening in the course of the closing movement in a first closing phase and are moved into the passage opening in a second closing phase, are basically known.

On the one hand, there are swivel-sliding doors in which a closing drive ensures a movement of the swivel-sliding door essentially parallel to a vehicle wall, with this parallel movement changing into a transverse movement, i.e. a movement in the direction of the vehicle wall, due to a deflected guide. By combining both movement phases in one movement sequence, the entire kinetic energy of a door leaf of the pivoting sliding door is transferred from the parallel movement to the transversal movement. This sometimes requires considerable contact pressure Swivel-sliding door in the passage opening and thus correspondingly strong pinching forces on a main closing edge of the swivel-sliding door, which results in an increased risk of injury for passengers.

In order to minimize this risk of injury, there are, on the other hand, swivel sliding doors in which a first guide device with a first closing drive is provided for the first closing phase and a second guide device with a second closing drive is provided for the second closing phase, the second guide device being a swivel mechanism. This means that both movement phases are kinematically decoupled. Such a pivoting sliding door is in AT 007065 U1 disclosed. Here, the parallel movement is conveyed by the first guide device and the first locking drive, which guide device and which locking drive can be coordinated with an optimal acceleration of the door leaf of the swivel-sliding door and which define the pinching forces on the main closing edge. The pivoting mechanism and the second closing drive move the door leaf into the passage opening, ie the pivoting mechanism and the second closing drive only mediate the subsequent transversal movement. The technical environment will continue to be discussed EP 2 899 091 A1 referred.

The disadvantage here is that the design of the swivel sliding door is expansive, which makes it correspondingly heavy, since two guide devices and two closing drives have to be provided due to the decoupling of the closing phases. In particular, the size of the swivel mechanism is sometimes problematic, as it narrows the opening and prevents passengers from getting in and out.

OBJECT OF THE INVENTION

It is therefore an object of the present invention to provide a pivoting sliding door which overcomes the disadvantages of the prior art. In particular, a pivoting mechanism of the pivoting sliding door should save space and be easily trained. Furthermore, the pivoting mechanism should be economical to produce and flexible in use.

This task is carried out in a pivoting sliding door for closing an opening in a vehicle wall

• at least one door leaf and
• at least one pivoting mechanism for moving the door leaf between a pivoted-in position and a pivoted-out position along a pivoting path,

where the pivot mechanism

• a support frame provided in a direction of passage for movable storage, which support frame has a support plate connected to the door leaf and a locking shaft, and
• a support bracket that is permanently intended to be connected to a vehicle wall

includes,

• solved according to the invention in that
• the support frame further has a lever arrangement, which lever arrangement can be brought into and out of an over-center position for locking the door leaf by means of the locking shaft,
• wherein an end section of the lever arrangement is guided on the support console,
• and a toothed ring which is firmly connected to the support frame, preferably the support plate, is provided and which meshes with a pinion arranged on the lever arrangement during the movement of the door leaf between the swung-in position and the swung-out position.

In summary, it can be stated that the swivel sliding door according to the invention has at least one swivel mechanism which includes the support frame and the support console, the support frame holding the door leaf indirectly, i.e. by arranging one or more elements between the support frame and the door leaf, or directly, i.e. without any further elements between Support frame and door leaf. While the support console is intended for a fixed connection to the vehicle wall, which can be a vehicle side wall and/or a vehicle ceiling and/or a vehicle floor, the support frame is intended for movable storage in the direction of passage along the pivot path in order to achieve this To move the door leaf from the swung-in position to the swung-out position and vice versa. Regardless of whether the support frame is connected directly or indirectly to the door leaf, the movement of the support frame is transmitted to the door leaf. When the door leaf is in the swung-in position, it closes the opening in the vehicle wall.

To initiate and maintain the pivoting movement of the door leaf, the lever assembly is connected to the locking shaft. By rotating the locking shaft, a movement can be transmitted to the lever arrangement, which movement causes the pinion to roll on the ring gear and the end section of the lever arrangement guided on the support console is displaced. As a result, the support plate and, as a result, the door leaf are displaced in the direction of passage between the swung-in position and the swung-out position along the swivel path.

In addition, the lever arrangement can be brought into an over-center position by rotating the locking shaft. In the swiveled-in position of the swivel sliding door according to the invention, the lever arrangement is in the over-center position, which over-center position can be released by an opposite rotation of the locking shaft. In the over-center position, the door leaf cannot be opened by pressure, in particular against an inside of the door leaf, due to the locking of the lever arrangement - without articulation of the locking shaft -, which prevents unwanted swinging out.

By using the pinion and the ring gear, which pinion and which ring gear form a gear transmission, an individual translation can be achieved. This means that it is possible that just a slight rotation of the locking shaft is sufficient to achieve a large swivel path. The result of this is that - compared to the prior art - the design of the pivoting mechanism can be significantly reduced without shortening the pivoting path. This can save weight on the one hand and space on the other. Due to the smaller design and the lower weight, costs can also be saved in the production of the pivoting mechanism, i.e. the pivoting sliding door according to the invention can be produced more economically than the pivoting sliding doors known from the prior art.

Of course, it is also possible to achieve a specific pivoting path by adjusting the lever geometry.

By means of the gear ratio of the pinion and ring gear and/or by means of the lever geometry of the lever arrangement So the pivoting path of the pivoting sliding door according to the invention can be influenced.

• der erste dieser Hebel als Winkelhebel ausgebildet ist und mit seiner Drehachse drehbar an der Tragplatte gelagert ist sowie mit der Verriegelungswelle zur Übertragung einer Drehbewegung wirkverbunden ist und
• der zweite dieser Hebel mit dem Endabschnitt an der Tragkonsole geführt ist.

In an embodiment variant of the invention it is provided that the lever arrangement comprises two levers, which levers are each connected to one another at a first end by means of a joint, wherein

• the first of these levers is designed as an angle lever and is rotatably mounted on the support plate with its axis of rotation and is operatively connected to the locking shaft for transmitting a rotary movement and
• the second of these levers is guided with the end section on the support console.

A specific pivoting path can thus be achieved by adjusting the dimensions of the angle lever and the second lever. This means that the pivoting path can also be influenced by changing the length of the angle lever and the second lever.

In order to prevent unwanted opening (movement from the swung-in position in the direction of the swung-out position) of the swivel sliding door according to the invention, in a further embodiment variant of the invention it is provided that when the dead center is reached, a connecting line between the axis of rotation of the angle lever and the joint as well as a connecting line between the end section of the second lever and the joint lie on a common straight line. The angle lever and the second lever are thus brought into the over-center position to lock the door leaf, as a result of which movement of the lever arrangement is no longer possible without external influence.

A movement can be transmitted to the angle lever using the locking shaft. In order to ensure this is structurally simple and fail-safe, there is another Embodiment variant of the invention provides that the support frame comprises a connecting arm, which connecting arm is connected to the lever arrangement at a first end and is in engagement with the locking shaft at a second end.

It is conceivable that the connecting arm at the first end is connected in a rotationally fixed manner to the axis of rotation of the angle lever. Due to the rotation-proof connection between the connecting arm and the angle lever, the rotational movement of the locking shaft leads to the tilting of the angle lever already mentioned above.

So that the connecting arm transmits the rotational movement of the locking shaft to the lever arrangement in the most fail-safe and structurally simple manner and ensures the pivoting movement of the swivel sliding door according to the invention, it is provided in a further embodiment variant of the invention that the locking shaft comprises a pinion and the second end of the connecting arm is designed as a ring gear , whereby the pinion and ring gear mesh with each other. This means that the pinion is connected to the locking shaft in a rotationally fixed manner and is in engagement with the second end of the connecting arm, which is designed as a ring gear. Here too, the pinion and ring gear are characterized by their simple design, their robustness and their high efficiency.

The transmission ratio between the pinion, which is non-rotatably connected to the locking shaft, and the second end of the connecting arm, which is designed as a ring gear, serves for regulation and influences the performance of a locking drive.

From a control technology point of view, a large transmission ratio between pinion and ring gear is advantageous, as this means that a control unit receives many displacement sensor pulses per swivel path.

In order to ensure that the pinion and the ring gear can be easily manufactured, a further embodiment variant of the invention provides that the pinion is designed as an externally toothed spur gear and the ring gear is designed as an internally toothed spur ring. The advantages here are the simple design and the robustness of both the externally toothed spur gear and the internally toothed spur gear as well as the high efficiency of this gear transmission.

In order to additionally counteract an unwanted movement of the door leaf into the swung-out position - after the lever arrangement has exceeded the dead center and is therefore in the over-center position - it is provided in a further embodiment variant of the invention that the support frame comprises a compression spring connected to the lever arrangement, which Compression spring is designed to counteract a movement of the door leaf into the swung-out position after a dead center of the lever arrangement has been exceeded.

It is conceivable that the compression spring is connected with its first end to the second end of the angle lever and is attached or tied to the support console with its second end.

In the swung-in position, the compression spring is in a tensioned state, whereby the compression spring counteracts the door leaf from swiveling out by pushing the lever arrangement further into the over-center position. If the dead center of the lever arrangement is overcome by means of the locking shaft when the lever arrangement is moved from the swung-in position to the swiveled-out position, the compression spring relaxes. Ie when exceeding the Dead center of the lever arrangement, the compression spring supports the movement of the lever arrangement into the swung out position.

The compression spring therefore represents a dead center spring, also called an over-center spring.

• die Tragkonsole eine Führung umfasst,

wobei das Führungselement verschiebbar in der Führung geführt ist. Das Führungselement wirkt somit mit der Führung, welche mit der Tragkonsole fest verbunden ist, d.h. bezüglich der Tragkonsole ortsfest ist, zusammen. Diese Anordnung stellt eine einfache und kostengünstige Fertigung sicher, da insbesondere die Führung eine leicht herstellbare Geometrie aufweisen kann.In a further embodiment variant of the invention it is provided that

• the end section has a rotatable guide element and
• the support console includes a guide,

wherein the guide element is slidably guided in the guide. The guide element thus interacts with the guide, which is firmly connected to the support console, ie is stationary with respect to the support console. This arrangement ensures simple and cost-effective production, since the guide in particular can have an easy-to-produce geometry.

It is conceivable that the guide element is designed as a roller. For example, the roller is made of stainless steel, which makes it durable.

In a further embodiment variant of the invention it is provided that the pivoting sliding door has a closing drive for driving the locking shaft. Actuation of the closing drive means that the support frame and the door leaf connected to it can be moved in the direction of passage.

In order to ensure that the support frame can be moved on the support console as smoothly as possible, a further embodiment variant of the invention provides that the support console has a guide wheel on which the support frame is movably mounted.

For example, the support frame can be movably mounted on the guide wheel by means of a linear ball guide.

It is conceivable that the support frame includes a carriage, which carriage is slidably mounted on the guide wheel. The carriage is preferably connected to the support plate; The carriage and the support plate are particularly preferably made in one piece.

WAYS OF CARRYING OUT THE INVENTION

Fig. 1 shows an axonometric view of an embodiment of the swivel sliding door 21 according to the invention in a swung-in position 3 - ie with the passage opening 31 in a vehicle wall 27 closed, while Fig. 2 an axonometric view of the swivel sliding doors 21 according to the invention in a swung out 4 and pushed open position 25 - ie with the passage opening 31 completely open.

The transition between the swung-in position 3 and the swiveled-out position 4 thus represents a first opening phase, during
the transition between the swung-out position 4 and the pushed-on position 25 represents a second opening phase. When closing it is the other way around. The transition between the pushed-out position 25 and the swung-out position 4 represents a first closing phase and the transition between the swung-out position 4 and the Position 3 is the second closing phase.

In this exemplary embodiment, the pivoting sliding door 21 is shown with two door leaves 1, with the invention also being used for pivoting sliding doors 21 with only a single door leaf 1.

Two pivoting mechanisms 2, in particular a support bracket 7 each, are firmly connected to a vehicle ceiling (not shown), which is an extension of the vehicle wall 27, each at the outer edge of the passage opening 31. A further guide round 29 is fastened between the pivoting mechanisms 2 and extends in a direction essentially parallel to the passage opening 31, this is in Fig. 3 - Fig. 5 clearly visible, with all three figures showing a top view of the swivel sliding door 21 according to the invention. In Fig. 3 the swivel sliding door 21 according to the invention is in the swung-in position 3, while in Fig. 4 and Fig. 5 the swivel-sliding door 21 according to the invention is shown in the swung-out position 4, the swivel-sliding door according to the invention being in Fig. 5 is also in the pushed-on position 25. In all three Figures 3 - 5 the door leaves 1 are not shown in order to make the structural design of the swivel sliding door 21 according to the invention more visible. In an operating state, the pivoting sliding doors 21 are arranged on the outside of the door leaf supports 28.

On the further guide wheel 29, two carriages with door leaf carriers 28 are movably mounted, the direction of movement of which thus extends in the direction essentially parallel to the passage opening 31, with a door leaf 1 being attached to each door leaf carrier 28 (see Fig. 1 and 2 ).

That is, in this exemplary embodiment, the door leaves 1 are indirectly connected to the pivoting mechanisms 2, in particular to the support plate 9.

A closing drive 26 is also arranged on both sides of the passage opening 31, with one of the two closing drives 26 being responsible for the parallel movement of the door leaves 1 to the vehicle wall 27 or to the passage opening 31 - i.e. the movement from the swung-out position 4 into the pushed-on position 25 and vice versa - and the other of the two locking drives 26 ensures the subsequent transverse movement of the door leaves 1 - i.e. the pivoting between the swung-in position 3 and the swung-out position 4 and vice versa.

In Fig. 6 a side view of the swivel sliding door 21 according to the invention including the swivel mechanism 2 can be seen in the swung-in position 3, while Fig. 7 shows a side view of the swivel sliding door 21 according to the invention including the swivel mechanism 2 in the swung out position 4.

In these two figures it can be seen particularly clearly that the door leaf 1 can be moved by means of the pivoting mechanism 2 between the pivoted-in position 3 and the pivoted-out position 4 along a pivoting path x. In this context, it should be mentioned that the pivoting path x and a passage direction 5 are essentially parallel in this exemplary embodiment.

Fig. 8 shows a side view of the pivoting mechanism 2 in the pivoted position 3 in detail, while Fig. 9 a side view of the swivel mechanism 2 in the swung out position 4 shows in detail. The pivoting mechanism 2 has a support frame 6 provided for movable storage in the direction of passage 5 and a fixed connection the extended vehicle wall 27 provided support bracket 7.

Part of the support console 7 is a guide round 19, which is aligned essentially parallel to the direction of passage 5 or to the pivoting path x and on which the support frame 6 is movably mounted. The support frame 6 in turn comprises a support plate 9 connected to the door leaf 1 - by means of the further guide round 29 and by means of the carriage, which has the door leaf supports 28, a locking shaft 11 and a lever arrangement 8, which has two levers 12, 13, the both levers 12, 13 are each connected to one another at a first end 12a, 13a by means of a joint 22. The first 12 of the two levers 12, 13 is designed as an angle lever 12 and has an axis of rotation 20 with which it is rotatably mounted on the support plate 9. The second 13 of these levers 12, 13 is guided with an end section 13b on the support bracket 7, the end section 13b having a rotatable guide element 23, namely in this exemplary embodiment a roller made of stainless steel, for example, and the support bracket 7 comprising a guide 24, in which guide 24 the guide element 23 is slidably guided.

A pinion 14 rotatably connected to the joint 22, which in this exemplary embodiment is designed as an externally toothed spur gear, and a ring gear 15 which is firmly connected to the support plate 9 and which in turn is designed as an internally toothed spur gear, mesh with one another.

By means of the transmission ratio of pinion 14 and ring gear 15 on the one hand and/or by means of a lever geometry of the lever arrangement 8 on the other hand, the pivoting path x of the pivoting sliding door according to the invention can be influenced.

In order to initiate and maintain the pivoting movement of the door leaf 1, the angle lever 12 is operatively connected to the locking shaft 11, which has a non-rotatably connected pinion 17 and is driven by one of the two locking drives 26. For this purpose, the support frame 6 comprises a connecting arm 16, which is connected at a first end 16a in a rotationally fixed manner to the axis of rotation 20 of the angle lever 12 and whose second end 16b is designed as a ring gear 18, the pinion 17 and the ring gear 18 being used to transmit the rotational movement of the locking shaft 11 on the lever arrangement 8 comb together. This causes the angle lever 12 to tilt, the pinion 14, which is rotatably connected to the joint 22, to roll on the ring gear 15 and the guide element 23 of the second lever 13 in the guide 24 to be displaced accordingly. As a result, the support frame 6 moves along the guide circle 19 of the support bracket 7. In detail, the support plate 9 and, along with it, the door leaf 1 are moved in the direction of passage 5 between the pivoted-in position 3 (see Fig. 6 and 8th ) and the swung out position 4 (see Fig. 7 and 9 ) shifted along the swivel path x.

The lever arrangement 8 is for locking the door leaf 1 in the swung-in position 3 in an over-center position (see Fig. 8 ) can be brought, which prevents the swivel sliding door according to the invention from opening unintentionally. As soon as the lever arrangement 8 reaches the dead center, a connecting line AC between the axis of rotation 20 and the joint 22 and a connecting line BC between the end section 13b of the second lever 13 and the joint 22 lie on a common straight line. In the over-center position, the door leaf 1 cannot be opened by pressure, in particular against an inside of the door leaf 1, due to the locking of the lever arrangement 8 - without articulation of the locking shaft 11 -, thereby preventing unwanted swinging out.

In order to additionally counteract an unwanted movement of the door leaf 1 into the swung-out position 4 - after the lever arrangement 8 has exceeded the dead center and is therefore in the over-center position - the support frame 6 comprises a compression spring 10. The compression spring 10 is with its first end 10a the second end 12b of the angle lever 12 is connected and the compression spring 10 is attached to the support bracket 7 with its second end 10b. In the swung-in position 3, the compression spring 10 is in a tensioned state (see Fig. 8 ), whereby the compression spring 10 counteracts the swinging out of the door leaf 1 by pushing the lever arrangement 8 further into the over-center position. If the dead center of the lever arrangement 8 is overcome when the lever arrangement 8 is moved from the swung-in position 3 to the swiveled-out position 4 by means of articulation of the locking shaft 11, the compression spring 10 relaxes. That is, when the dead center of the lever arrangement 8 is exceeded, the compression spring 10 supports the movement of the lever arrangement 8 into the swung out position 4. When the swung out position 4 is reached (see Fig. 9 ), the compression spring 10 is then again in a tensioned state.

By using the pinion 14 connected to the joint 22 and the ring gear 15, which form a gear transmission, an individual translation can be achieved. Ie it is possible that only a slight rotation of the locking shaft 11 is sufficient to realize a specific pivoting path x. The result of this is that - compared to the prior art - a significantly smaller design of the pivoting mechanism 2 can be achieved without shortening the pivoting path x. This can save weight on the one hand and space on the other.

Additionally/alternatively, it is also possible to influence the swivel path x by adjusting the lever geometry.
