Description

FIELD OF THE INVENTION

The invention relates to a locking device for pivoting sliding doors of vehicles, the locking device comprising a lever arrangement which can be brought into an over-center position for locking the pivoting sliding door in the closed position. In particular, the invention can be used in vehicles for public passenger transport, where the vehicle comprises at least one door leaf which can be displaced in the longitudinal direction of the vehicle and a drive for moving the door leaf between a closed and an open position.

The locking device is usually only activated if the door system is faulty or defective or should not be opened.

STATE OF THE ART

Generic pivoting sliding doors for closing a passage opening in a vehicle wall, which pivoting sliding doors are pushed in the course of the closing movement in a first closing phase essentially parallel to the door leaf in front of a passage opening and in a second closing phase are placed in the passage opening essentially normal to the door leaf, are basically known.

A drive ensures a movement of the pivoting sliding door that is essentially parallel to a vehicle wall, with this parallel movement being transformed into a movement transverse thereto, that is to say a movement in the direction of the vehicle wall, due to a deflected guide. Locking the door in the closed position in an over-center position prevents the door from opening unintentionally if a passenger presses against the door leaf from the inside. At the same time, however, it should also be possible to open the door in an emergency where the drive for opening the pivoting sliding door is not available, for which purpose the over-center position must be overcome. For this purpose, various types of emergency release are known from the prior art.

the WO 2015/177148 A1 shows a locking device with an actuating element formed on a reversing lever for eliminating an over-center position between the reversing lever and a locking lever. This can be, for example, a bolt protruding from the reversing lever. The over-center position can be resolved by turning the reversing lever by means of this bolt. This actuating element can, for example, be actuated manually in an emergency using a Bowden cable, which means that the door can also be opened without actuating the drive. The bolt must be moved here along a curved path.

the EP 3421700 A1 relates to a door drive with an over-center lock as the main lock and with an emergency release comprising a mobile carrier and an emergency release cable. When the emergency release cord is pulled, the mobile carrier moves in one direction ( 4th ), whereby a drive nut can be moved along a drive shaft into the open position of the doors and actuates a complex and large-sized isolating lock mechanism via two arms.

OBJECT OF THE INVENTION

It is therefore an object of the present invention to provide a locking device with an emergency release which overcomes the disadvantages of the prior art. In particular, the locking device with emergency release should be designed to save space and be easy to operate.

DISCLOSURE OF THE INVENTION

This object is achieved by a locking device according to claim 1. The starting point is a locking device for pivoting sliding doors of vehicles, in particular of vehicles for public transport, wherein the vehicle comprises at least one door leaf that can be displaced in the longitudinal direction of the vehicle and a drive for moving the door leaf between a closed and an open position, and the locking device is a lever arrangement includes, which can be brought into an over-center position for locking the pivoting sliding door in the closed position.

• - dass der Mitnehmerhebel durch einen geradlinig verfahrbaren Mitnehmer betätigbar ist, um die Übertotpunktlage aufzulösen.

According to the invention it is provided

• - That the lever arrangement comprises a locking element, a deflecting element, an actuating lever and a driver lever, all of which can be moved parallel to the same plane,
• - that the locking element can be moved in a straight line,
• - That the deflecting element is rotatably connected to the locking element at one end about a first axis, which is not stationary, and is rotatably connected to one end of the actuating lever at an opposite end about a second axis, which is not stationary,
• - that the actuating lever is rotatably connected with its end opposite the second axis to a third axis which is stationary,
• - That the operating lever is firmly connected to a driver lever so that the operating lever can be rotated about the third axis by means of the driver lever,
• - That the deflection element and the actuating lever can be brought into a locked position by rotating the driver lever, in which the connecting line between the first axis and the second axis and the connecting line between the second axis and the third axis are in over-center position with respect to the connecting line between the first Axis and the third axis,
• - That this over-center position can be resolved in the sense of an emergency release by turning the driver lever in the opposite direction, and
• - That the driver lever can be actuated by a driver that can be moved in a straight line in order to resolve the over-center position.

Because the locking element, deflection element, actuating lever and driver lever can all be moved parallel to the same plane, the height of the locking device, measured normal to the plane (s) of movement, can be kept low. The locking device with emergency release can therefore easily be accommodated in the area of the pivoting sliding door, e.g. above or above the side of the pivoting sliding door in the vehicle. The locking device with emergency release is usually located in the area of the drive.

Because the driver lever can be actuated by a driver that can be moved in a straight line in order to resolve the over-center position, the driver can be operated simply by a straight movement in an emergency. The straight movement of the driver causes a rotation of the driver lever. The driver can be actuated electrically or mechanically.

The locking element, deflection element and actuating lever are part of the main locking mechanism that is actuated by the drive during normal operation. Driver lever and driver are part of the emergency release, with which the locking element, deflection element and operating lever can be operated in an emergency and with which the locking device can be brought into the open position without the drive provided for normal operation.

Deflection element and actuation lever can be designed as straight levers in a simple manner.

The locking element comprises a part which can effect a locking in a corresponding counterpart, for example a locking bolt.

Various designs are conceivable for the design of the driver lever and the driver. In one embodiment it is provided that the driver engages from the outside on a longitudinal side of the driver lever. In this case, the driver can only act on the driver lever from one side and resolve the over-center position. It is not possible to use the same driver to restore the over-center position, i.e. the closed position of the locking device. However, this is not absolutely necessary for an emergency release. In this embodiment, the driver lever can simply be designed as a straight lever.

In an alternative embodiment of the driver lever and driver it is provided that the driver is mounted in a recess of the driver lever, the shape of the recess causing the driver lever to rotate when the driver moves in a straight line. It is possible here to use the same driver to resolve the over-center position when the driver moves in one direction and to restore the over-center position when the driver moves in the opposite direction. For this purpose, the recess can have an approximately angled shape. Correspondingly, the driver lever can then also be designed as an angle lever.

It can be provided that the driver is attached to a cable of a cable, e.g. a Bowden cable, which can be pulled by a user in an emergency. The rope of the cable pull is guided in such a way that the driver moves in a straight line.

Alternatively, it can be provided that the driver is attached to a rod that can be moved by a user in an emergency. The rod is guided in such a way that the driver moves in a straight line. For example, the user could pull the rod directly or indirectly, for example via a handle connected to the rod or a rope attached to the rod.

In one embodiment it is provided that the locking element that can be moved in a straight line and the driver that can be moved in a straight line can be moved parallel to one another. That way you can Space normal to the direction of movement of the locking element and driver can be saved.

In one embodiment it is provided that the locking element, the deflecting element, the actuating lever and the driver lever are arranged on one side of a base plate and the deflector element, operating lever and driver lever are rotatably mounted in a plane parallel to the plane of the base plate. In this way, all elements of the lever arrangement are accessible from one side and take up the least possible space normal to the plane of the base plate. The base plate itself can of course also have openings for reasons of its own weight or accessibility to individual elements of the locking device. The first, second and third axes are essentially normal to the plane of the base plate.

With regard to the base plate, it can be provided that the lever arrangement, in particular the actuating lever, rests against a first stop on the base plate in a defined position in the locked position of the locking device. In this way, the locked position, i.e. the over-center position, can be clearly defined.

With regard to the base plate, it can alternatively or additionally be provided that the lever arrangement, in particular the actuating lever, rests in a defined position on a second stop on the base plate in the released position of the locking device. This allows the released position to be clearly defined.

The setting of the locked and the released position can be supported by a spring. For this purpose, it can be provided that the locking element can be pretensioned by a spring, so that the spring supports the movement of the locking element from the locked to the released position. For this purpose, the spring can be fastened on the one hand to the locking element and on the other hand, if necessary, to the base plate.

WAYS OF CARRYING OUT THE INVENTION

1 shows an axonometric view of a pivoting sliding door in a pivoted position in a vehicle wall of a vehicle 1 , ie with the passage opening closed. In this embodiment, the sliding door is with two door leaves 2 shown, the invention also being used for pivoting sliding doors with only a single door leaf 2 finds. The drive 3 as well as the locking device 4th are shown here as a common block with dashed lines, because they are not visible from the outside. The drive 3 can comprise several drive units, such as swivel drives and locking drives, for example per door leaf 2 a drive unit for pivoting the door leaves and a drive unit for moving the door leaves 2 along the vehicle wall of the vehicle 1 . However, the type and number of drive units are not essential to the present invention. In addition to the drive unit or units are in the drive 3 for the pivoting sliding doors, and also outside the drive 3 , usually guides and support devices for the door leaves 2 intended.

The door leaves 2 are located in 1 in the closed position. When the sliding door is opened, the door leaves 2 first swiveled out of the passage opening essentially normal to the vehicle wall in a first step and shifted away from the passage opening parallel to the vehicle wall in a second step. When closing it is the other way around, as the door leaves are 2 shifted from the pushed-on position in a first step again parallel to the vehicle wall into the pivoted position and in a second step pivoted back into the passage opening essentially normal to the vehicle wall. In this swiveled-in state, as shown in 1 is shown, the door leaves 2 by means of the Locking device 4th secured by the locking device 4th so in the drive 3 intervenes so that it cannot move. The lever assembly of the locking device 4th is in the locked position, the over-center position.

A first actuating device is located on the outside of the vehicle wall 13th intended for the emergency unlocking of the pivoting sliding doors. With this first actuator 13th the over-center position can be resolved mechanically or electrically, so that the door leaves 2 can be unlocked and without assistance from the drive 3 can be opened manually.

2 shows the same arrangement as in 1 from inside the vehicle 1 seen. The locking device according to the invention 4th as well as much of the drive 3 are located on the inside above the passage opening or the closed door leaves 2 and are covered by a cladding. The first actuator 13th the emergency release is visible here, but can only be operated from the outside. However, further actuation devices for the emergency release can be provided inside.

3 shows the locking device according to the invention 4th as well as part of the drive 3 according to 2 when the panel is removed. The dotted areas are intended to roughly indicate where the locking device is 4th and where parts of the drive are 3 are located.

The lever assembly of the locking device 4th comprises a locking element 5 , a deflection element 6th in the form of a straight lever, a straight operating lever 7th and a straight drive lever 8th all parallel to the same plane, here the plane of the baseplate 19th , are movable. The locking device 4th also includes a locking bolt 12th , the part of the locking element 5 and firmly connected to it and in a guided tour 20th (please refer 4-7 ) is performed. The locking element 5 can be moved in a straight line and actuates its locking bolt 12th , so pushes it out of the guide with its free end 20th addition to an interlock with a counterpart 21 of the drive 3 to effect, or pulls the free end in the other direction back into the guide 20th to unlock. The feather 14th showing the movement of the locking element 5 supported by the locked position in the released position is not in the locking element here 5 hooked. The counterpart 21 but can also be implemented in other ways, but must in any case directly or indirectly with the drive 3 be connected, so that this is prevented from moving in the locked position of the locking device. When the locking bolt 12th is extended, components of the drive 3 electronically and / or mechanically prevented from moving.

A pulley with a rope 15th on which a driver 11 is attached, is used on the longitudinal side of the driver lever 8th attack and turn it counterclockwise. This removes the over-center position of the lever arrangement and releases the lock, the locking bolt 12th so pulled to the left.

The functioning of the lever assembly is described in 4-7 recognizable. The deflection element 6th is at one end about a first axis A. , which is not stationary, rotatable with the locking element 5 connected and at an opposite end about a second axis B. which is not stationary, rotatable with one end of the operating lever 7th tied together. The operating lever 7th is with his the second axis B. opposite end with a third axis C. rotatably connected, which is stationary. The operating lever 7th is firmly connected to a driver lever 8, 9 so that the actuating lever 7th by means of the driver lever 8.9 around the third axis C. is rotatable. The deflection element 6th and the operating lever 7th are brought into a locked position by rotating the driver lever 8.9, in which the connecting line between the first axis A. and the second axis B. as well as the connecting line between the second axis B. with the third axis C. are in over-center position with respect to the connecting line between the first axis A. and the third axis C. . This over-center position can be eliminated by moving the driver lever 8.9 11 is set in rotation from left to right, so that the operating lever 7th around the third axis C. rotates upwards, whereby the second axis also rotates B. and the left end of the deflector 6th move up. The second axis B. exceeds dead center, i.e. the connecting line between the first axis A. and third axis C. , and the locking element 5 , and thus the locking bolt 12th are dragged to the left.

The emergency release is thus carried out by the driver lever 8, 9 and the driver 11 realized and thus forms a secondary system to the system of the main locking, which is the locking element 5 , including locking bolts 12th and its leadership 20th , the deflection element 6th and the operating lever 7th contains. The main lock is in normal operation by the drive 3 actuated. In an emergency where the drive 3 the unlocking cannot be effected by a user on the rope 15th of the cable pull and thereby the one on the cable 15th attached driver 11 against the driver lever 8, Press 9 so that its rotation unlocks.

The locking element that can be moved in a straight line 5 and the straight-line movable driver 11 can be moved along straight lines running parallel to one another. Of course, instead of a cable pull, other variants of guiding the driver are also possible 11 conceivable. For example, the driver could 11 be attached to a rod that can be moved by a user in an emergency.

The locking element 5 , including locking bolts 12th and its leadership 20th , the deflection element 6th , the operating lever 7th and the driver lever 8,9 are on the front side of a base plate 19th arranged. Deflection element 6th , Operating lever 7th and driver levers 8,9 are in a plane parallel to the plane of the base plate 19th rotatably mounted. The third axis C. is in the base plate 19th stored, so is the leadership 20th for the locking bolt 12th on the base plate 19th attached.

On the baseplate 19th is a first attack 16 attached to which the operating lever 7th in the locked position of the locking device 4th is present, see 4th and 6th . On the baseplate 19th is also a second stop 17th attached to which the operating lever 7th in the released position of the locking device 4th is present, see 5 and 7th .

The locking element 5 is in the locked position by a spring 14th opposite the base plate 19th preloaded so that the spring 14th the movement of the locking element 5 of the locked position, see 4th and 6th , in the released position, see 5 and 7th , supports. The spring is in the released position 14th relaxed. The feather 14th can, as here, on a bevelled part of the base plate 19th be anchored.

On the baseplate 19th is also a sensor 18th provided, which measures whether the locking element 5 is in the locked or released position. To this end, the locking element 5 an extension that is in the locked position outside of the guide 20th comes to rest and a swivel arm of the sensor 18th mechanically deflects, the sensor 18th above the guide 20th is arranged.

4th shows a plan view of the locking device according to the invention 4th the end 3 in the locked position, 5 a plan view of the same locking device 4th in the solved position. The arrow in 4th below gives the direction of movement of the driver 11 to move from the locked position to the released position of the locking device 4th get.

the 6th and 7th show a locking device in which, in contrast to that from the 3-5 instead of a straight drive lever 8th a driver lever 9 with a recess 10 is provided. The driver 11 is in this case designed so that it, in addition to its attachment to the rope 15th , in the recess 10 is led. When the driver moves in a straight line 11 is due to the angular shape of the recess 10 the rotation of the drive lever 9 causes. The carrier lever 9 is according to the shape of the recess 10 designed as an angle lever.

6th shows a plan view of the locking device 4th in the locked position, 7th the top view of the same locking device 4th in the solved position.

8th FIG. 13 shows a rear view of a locking device from FIG 3-5 in the locked position. 8th thus shows the rear view of 4th . The driver 11 would therefore have to be shifted from right to left, see straight arrow, around the driver lever 8th to rotate and the locking device 4th to bring from the locked position shown in the released position. To the locking device 4th To bring the released position back into the locked position shown, the driver lever 8th be moved manually from left to right, according to the drawn curved arrow around the third axis C. .
