In the 1 is the construction of a two-leaf sliding door, eg for a tram, shown. At one in the upper area of the car body 1 arranged base plate 2 The electrical and mechanical components for the drive and the locking and unlocking are attached. On the base plate 2 is the control unit 3 arranged. The swing door can be used as a prefabricated module 4 in the door frame / car body 1 used and mounted. The two door leaves 5a and 5b are on roller carriages 6a and 6b attached, and each in curved roller guides 7a . 7b guided ( 2 ). To realize the transverse and longitudinal displacement of the door leaves 5a . 5b At these, in the upper and lower area, racks 8a . 8b . 8c . 8d arranged ( 1 ), with the upper racks 8a . 8b With the upper swivel gearboxes 9a . 9b and the lower racks 8c . 8d with the lower swivel gearboxes 9c . 9d engage. The racks 8a . 8b . 8c . 8d have curved start sections leading towards the door leaf 5a . 5b demonstrate. The synchronously working swivel gearbox 9a . 9b . 9c . 9d are each arranged in a housing which is movable on the respective vertical connecting shafts 10a . 10b are stored.

Furthermore, there is a plate at a base in the upper part of the car body 2 mounted drive unit 12 consisting of a horizontally arranged DC motor 12a that by means of two sprocket gears 12b . 12c and a toothed belt transmission 12d an opposite movement of the not shown connecting shafts with the pulleys 12e . 12f generated. Through the toothed belt transmission 12d is the drive torque from the pulleys 12e . 12f the sprocket gear 12b . 12c each with tension rollers 13 on the synchronizing discs of the upper swivel gear 9a . 9b transfer. The tension rollers are located on a tensioning device, which is attached to the base plate 5 is attached. The two sprocket gears 12b . 12c are rigidly connected by a coupling. The transmission of torque from the DC motor 12a to the gear shaft is done by a feather key connection. The motor housing is thereby rotatable about its axis.

The swivel gearbox 9a . 9b . 9c . 9d are in the closed state of the door leaves in an approximately parallel to the vehicle longitudinal center axis starting position. In this is the support roller of the respective pivot gear in the radius of the curved initial section of the respective rack. By the rotation of the racks 8a . 8b . 8c . 8d engaged drive pinion of the rotary gear 9a . 9b . 9c . 9d The drive pinion moves along the curved start section and presses the respective door leaf 1a . 1b transverse to the axis of the opposite support roller from the side wall level out in the displacement position for the subsequent longitudinal displacement of the door leaf. The swivel gear is pivoted about the vertical axis by a rotation angle of about 90 ° to a stop. The rotational movement of the drive pinion is thus converted into a translational movement transversely and longitudinally to the vehicle longitudinal central axis and thereby the respective door leaf 1a . 1b out of the side wall level and at the same time slightly moved in the longitudinal direction. The longitudinal displacement of the door leaves 1a . 1b parallel to the vehicle outer wall, until the complete release of the door opening is, by the further rotational movement of the with the straight portion of the racks 8a . 8b . 8c . 8d engaged pinion of the swivel gear 4a . 4b . 4c . 4d reached. The above-explained manner of the transverse and longitudinal displacement of the door leaves is from the DE 101 16 580 A1 known. The following is the locking and unlocking for the two door leaves 5a . 5b as well as the emergency release and its decoupling.

The functional elements required for this purpose are on a below the base plate 5 arranged mounting plate 11 mounted by spacers 11a at the base plate 5 is attached ( 2 ). The mounting plate 11 is in the area of the center of the door and at the level of the roller guides 7a . 7b arranged.

For locking is on the mounting plate 11 , on the side facing away from the door opening, a bearing block 14 fastened in which a spring-loaded locking bracket 15 swiveling, in a horizontal axis of rotation 14a , stored ( 3 and 4 ). The rotation axis 14a is at a defined distance to the mounting plate 11 arranged and is located approximately at the height of the upper edge of the trolley 6a . 6b , The longitudinal center axis of the locking bracket 15 is right in the middle of the door opening. At the to the axis of rotation 14a opposite end of the locking bracket 15 is located on this one bracket 15a , in the symmetrical two lying in a horizontal plane cam rollers 15b . 15c on parallel to the longitudinal center axis of the locking bracket 15 aligned bolt 15d . 15e are stored. The two cam rollers 15b . 15c act as locking means after closing the door leaves 5a . 5b - In this state, the two roller carriages are 6a . 6b in the area of the middle of the door opening, in the immediate vicinity - in on the roller carriage 6a . 6b arranged lateral recesses 6c . 6d intervention. In this state, the two roller carriage 6a . 6b do not move and the door leaves 5a . 5b are locked. The roller carriages 6a . 6b each on their inside, opposite to the recesses 6c . 6d , sloping contact surfaces 6e . 6f ( 4 ). During the synchronous counter-rotating closing movements of the door leaves 5a . 5b the roller carriages arrive 6a . 6b with their sloping contact surfaces 6e . 6f in contact with the cam rollers 15b . 15c of the locking bracket 15 , drive underneath and lift the locking bar 15 at. After reaching the end position of the two roller carriages 6a . 6b , in the closed state of the two door leaves 5a . 5b , are the cam rollers 15b . 15c immediately above the recesses 6c . 6d and are determined by the dead weight of the locking bar 15 and the spring force applied to this pressed into the recesses or snap into this. In the 3 and 4 is the locking bar 15 shown in the locked position.

For unlocking is on the mounting plate 11 is a horizontally swiveling release lever 16 arranged. On the release lever 16 is a log 17 attached, which at its towards the locking strap 15 facing side with a horizontally guided role 17a equipped, which is the top of the log 17 surmounted. In place of the role 17a can also be used a deep groove ball bearing. The locking bracket 15 owns at its towards the log 17 pointing longitudinal side of a chamfer, not shown. By an operation of the unlocking lever 16 about its axis of rotation, in a pivoting direction counterclockwise, the role passes 17a of the log 17 in touching contact with the chamfer on the locking bracket 15 and raises this due to the further movement while overcoming the applied spring force. This also the cam rollers 15b . 15c lifted and get into a position above the roller carriage 6a . 6b , The on the roller carriage 6a . 6b attached door leaves 5a . 5b can now be moved into a position releasing the door opening. In 3 is with 17 ' the location of the block indicated when this in one under the locking bracket 15 is in the pushed position.

To realize the unlocking by the operation of the unlocking lever, the reaction force of the DC motor is in the example shown 12a , whose housing is rotatable about motor axis, exploited ( 3 ). The rotational movement of the housing of the arranged in horizontal mounting position motor 12a is on a segment plate 18 transferred, which is connected to the motor housing. The segment plate 18 is in a lateral recess of the mounting plate 11 guided and surmounted the mounting plate 11 , The movement of the segmental flap 18 is by stops 20 limited. At the upwardly projecting portion of the segment plate 18 is a pull rod 19 pivotally attached, the rotational movement of the motor housing on the release lever 16 transfers.

The unlocking is initiated by the door opening command. The commissioning of the DC motor 12a generated drive energy is through the sprocket gear 12b . 12c , the toothed belt transmission and the swivel gearbox 9a . 9b . 9c . 9d on the door leaves 1a . 1b attached racks 8a . 8b . 8c . 8d transfer. The pivot gears, in conjunction with the outwardly bent portion of the racks, produce a counter-locking force, a blockage, due to the locked doors. As a result of this blockage, a reaction torque is generated on the DC motor, which causes the housing of the motor 12a turns around the drive axle. This rotational movement is via the segment plate 18 on the drawbar 19 transmitted to the release lever 16 hinged, which is moved in the counterclockwise direction and the release triggers. During the opening movement of the door leaves 5a . 5b remains the locking bracket 15 in the raised, unlocked position. During the closing movement of the door leaves in the reverse manner, as explained above, a blocking of the driving force, and the motor housing rotates in the opposite direction and transmits this movement to the pull rod 19 that the unlock lever 16 turns clockwise while the log 17 with the role 17a from the area of the locking bracket 15 moved out so that it moves by its own weight and the applied spring force down and the two cam rollers 15b . 15c on top of the roller guides 7a . 7b come to the edition. Thereafter, then again takes a lock in the manner already described.

Furthermore, a required for safety reasons manual emergency release is provided. The execution takes place either as an emergency release handle with square detent or as an emergency release button. It is also possible to integrate the external emergency release in the door leaf. A Bowden cable is attached to the emergency control device. The Bowden cables of which one is intended for the inside of the door and the other for the outside of the door, are up to the mounting plate 11 guided and in one on the mounting plate 11 attached bracket 22 held and on a spring-loaded pivot lever 23 by means of fastening nipples 21 attached and stretched by this. The functional elements for the emergency release are in 4 shown.

The axis of rotation of the pivot lever 23 is with 23a and the torsion spring with 23b characterized. Offset to the pivot axis 23a is on the pivot lever 23 is a bent tab 24 pivotal about the axis of rotation 24a held. Am to the axis of rotation 24a opposite end of the tab 44 is in this a vertically aligned bolt 25 rotatably arranged, in operative connection with another lever 26 stands. The lever 26 is on a shaft forming the vertical axis of rotation 26a rotatable on the mounting plate 11 attached. The lever 26 has one as a horizontal guide 26b serving recess. In the recess bounding the upper and lower portion of the lever 26 there are two congruent slots 26c in which the bolt 25 the tab 24 slidably guided. The two slots 26c thus form a vertical guide for the bolt 25 the tab 24 , The, as already explained, on the mounting plate 11 arranged and with the drawbar 19 in operative connection spring-loaded unlocking lever 16 , has at its to the point of articulation of the drawbar 19 opposite end of a semicircular or claw-shaped recess 16a that with the bolt 25 engaged, both during the locked and unlocked state of the lock. To ensure the Engagement of the bolt 25 in the recess 16a is on the lever 26 a spring hinged in the 4 not visible. In addition, a decoupling for the emergency release is provided, which from the 5 is apparent. In this figure, only the essential components for the decoupling are shown and identified by reference numerals. To decouple the emergency release is located on the downwardly extended shaft 26a of the lever 26 a spring-loaded rotary magnet 27 , A decoupling of the emergency release is effected by a signal triggered by the door control, by which the rotary magnet is supplied with voltage and the shaft 26a and with it the lever 26 rotates counterclockwise.

The The mode of operation of the emergency release and the decoupling is the following.

By operating the emergency handle is on the respective Bowden cable of the pivot lever 23 turned clockwise and thereby the tab 24 moved and in the slots 26c positively driven bolts 25 shifted in the direction indicated by an arrow A. As the bolt 25 with the release lever 16 is in engagement this is rotated about its pivot axis counterclockwise and thus the block 17 with his role 17a under the latch bracket 15 pushed, this raised, with the cam rollers 15b . 15c in a position above the roller carriage 6a . 6b reach.

To decouple the emergency release is the rotary magnet 27 energized and turns the shaft 26a and with it the lever 26 counterclockwise, causing the bolt 25 out of engagement with the claw-shaped recess 16a of the release lever 16 arrives. In this state, the emergency release is decoupled, upon actuation of the emergency release is the release lever 16 no longer moving and the locking state remains.

The decoupling is magnetized by an interruption of the voltage supply to the rotary 27 shut down. The wave 26a and the lever associated with it 26 are freely movable be moved back by the applied spring force to its original position. In this case, the bolt passes 25 again in engagement with the claw-shaped recess 16a of the release lever 21 and the emergency release can be re-activated if necessary.
