The door opening closing double-leaf sliding door consists of two Door leaves 1a and 1b, the outer sides in the closed state with the vehicle outer wall forming a plane. The door leaves 1a, 1b are in the upper area Roller carriage attached, each in a curved roller guide 2a and 2b, are guided (Fig.1). For transverse and longitudinal displacement of the door leaves are on this, in the upper and lower area, racks 3a and 3b attached, those with curved Initial sections are formed and with pivot gears 4a and 4b in engagement stand. Furthermore, located at the top of the car body on a Base plate 5 mounted drive unit 6, consisting of a horizontal arranged DC motor 6a, by means of two bevel gear 6b, 6c and a toothed belt transmission 6d an opposite movement on the connecting shafts produced with the toothed belt pulleys 6e, 6f. Through the toothed belt transmission 6d is the drive torque from the timing pulleys 6e, 6f of the bevel gear 6b, 6c respectively via tension rollers 7 on the timing pulleys of the upper pivot gear 4a, 4b transferred. The tension rollers are located on a tensioning device, which is attached to the base plate 5. The two bevel gear 6b, 6c are over a clutch connected together. The transmission of torque from DC motor 6a to the transmission shaft is effected by a feather key connection. The Motor housing is thereby rotatable about its axis.

The synchronously working swivel gear, which is movable on the respective Vertical connecting shafts 8a, 8b are stored, each in a housing arranged. If necessary, the connection shafts 8a, 8b are articulated connections adapted to the outer wall contour of the vehicle.

The swivel gear 4a, 4b 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 pivot gear 4a, 4b in the radius of the curved beginning portion of the rack 3a, 3b at. Through the rotation of the with the rack 3a, 3b engaged drive pinion of the pivot gear 4a, 4b, the drive pinion moves along the curved start section and presses the respective door leaf 1a, 1b about the axis of the opposite Support roller transversely from the side wall level out in the displacement position for the subsequent longitudinal displacement of the door leaf. This will be a swivel gear 4a about the vertical axis in the clockwise direction by a rotation angle of approx. 90 ° pivoted to a stop and the other swivel gear 4b in opposite direction. The rotational movement of the drive pinion is thus in a translational movement transversely and longitudinally to the vehicle longitudinal center axis converted and thereby the respective door leaf 1a, 1b from the side wall level out and at the same time slightly moved in the longitudinal direction. The longitudinal displacement the door leaves 1a, 1b parallel to the vehicle outer wall, until fully released the door opening, is characterized by the further rotation of the with the straight Section of the rack 3a, 3b engaged pinion of the pivot gear 4a, 4b achieved. in known manner, the door leaves 1a, 1b on roller carriage fixed in the stationary mounted on the car body curved roller guides 2a, 2b are guided. The above-explained manner of transverse and longitudinal displacement the door leaves is known from DE 101 16 580 A1.

For locking and unlocking the door leaves 1a, 1b are the required Locking elements 10 on the outer vertical longitudinal sides of the relevant Closing edges, as shown in Figure 2 can be seen. The complete construction of the inside the door frame arranged locking is shown in Figure 3. On the inside the door leaves 1a, 1b is at least one vertically guided roller 9, which in a holder 9a, at a defined distance from the inside of the door leaf 1a, 1b is held. A corresponding door leaf cutout of a door 1 or door leaf 1a, 1b with a roller 9 is shown in Fig. 3. The actual locking element 10 is arranged opposite to the inside of the door frame and as a single part also shown in FIG. On the inside of the door frame is a holder 11th fixed, which has a rear recess 11 a, within which the vertical Connecting shaft 8a or 8b extends, which is not shown in Fig. 3. At the in Looking from the front left, protruding portion 11b of the bracket 11 is a spring-loaded rotary latch or a pawl 12 horizontally pivotable about the axis of rotation 12a stored. The pivoting movement of the rotary latch 12 to the outside is through delimited a stop 11c. The rotary latch 12 has a protruding or protruding Lock body or portion 12b and opposite to this a nose 12c defining a semicircular or claw-shaped recess 12d. The claw-shaped Recess 12d encloses the during the locking process the inner side of the door leaf 1a arranged roller 9. The locking portion 12b is much longer than the nose 12c. The not visible in Fig. 3 tension spring for Rotary latch 12 is mounted on the rear portion of the bracket 11 and ensures that pivoted in the unlocked state of the rotary latch 12 against the stop 11c is and in a ready for intervention for the subsequent locking process Position is. For the final locking of the respective door leaf in the closed position, is on the bracket 11 a locking bracket 13th arranged. This is with its curved portion 13a in a lateral Section 11d of the holder 11 by means of a horizontal bolt 13b pivotally stored. The upper leg 13c of the bracket 13 has at its front end a downwardly directed bend 13d, at the means of a bolt 13e a movable roller 13f is mounted, wherein the bolt 13e via a lever arm 13g pivotally connected to a vertically disposed locking bar 14.

On the lower leg 13h of the locking bracket 13 is a tension spring 13i mounted, which is connected to the bracket 11. For locking the door leaf in the closed position (in this is the locking portion 12b the rotary latch 12 in a position parallel to the door leaf), is by the spring force the tension spring 13i of the locking bracket 13 pivoted about its axis of rotation 13b, whereby the roller 13f immediately before the locking portion 12b of the rotary latch 12 is moved and locked this. This locking process can additionally by the triggered movement of the locking rod 14, in Direction down, to be supported.

A release of the lock, so unlocking, is only then reached again, if by an operation of the locking bar 14 in opposite Direction, upwards, the locking bracket 13 in the clockwise direction in the Starting position is pivoted and the rotary latch 12 by a pivoting movement outward (clockwise) easily from the area of the locking bracket 14 can be moved out.

At the front end of the lower leg 13h of the locking bracket 13 are located there are two lying on a common axis holes 13j, which are for recording a bolt for fixing a rod for transmitting the vertical movement for locking and unlocking on another locking element.

The operation of the lock is the following.

During the closing movement of the door or the door leaves the arrives at the Located inside the door, vertically guided roller 9 in engagement with the semicircular or claw-shaped recess 12d of the rotary latch 12. Due to the leadership Pressing movement of the door in the direction of the closing edge of the rotary latch 12 continues counterclockwise or toward the middle of the door opening, pivoted. In this case, the roller 13f of the locking bracket 13 is in touching contact with the upper surface of the locking portion 12b and rolls on this. Of the Locking portion 12 b is pivoted to the opening of the bracket 13. To Reaching a position parallel to the door or door leaf of the locking bracket 13th pivoted by the applied spring force about its axis of rotation 13b down and the roller 13f passes immediately in front of the locking portion 12b. In this Condition is reached the final locking position.

On the rotary column or the vertical connecting shaft 8, 8a, 8b is equal to the rotary latch 12 additionally arranged a not visible in the drawing pen, the moves when opening the door or door leaves with the rotary column and in the open position of the door or door leaves the rotary latch locked so that this manually can not be moved back to its locking position.

The required actuators for locking and unlocking including a manually releasable emergency release and a decoupling of the emergency release are on a below the base plate 5 arranged mounting plate 17th mounted, which is fastened via spacers, not shown, to the base plate 5 (Figures 1, 2 and 4).

To trigger the required movements for unlocking immediately before the opening movement of the door leaves or the support for the lock During the closing movement of the door leaves 1a, 1b, the reaction force of Drive motor 6a, whose motor housing is rotatable about its axis, exploited become.

The rotational movement of the housing arranged in the horizontal mounting position Motors 6a is transferred to a segment plate 18, which is connected to the motor housing connected is. The segment plate 18 is in a lateral recess of the mounting plate 17 out and extends beyond the mounting plate 17. The rotational movement of the segment plate 18 is limited by two mounted on the mounting plate 17 stops 19 (Fig. 4). At the upwardly projecting portion of the segment plate 18 is a Tension rod 20 pivotally mounted, the rotational movement of the motor housing on a horizontal lever 21 transmits, the pivotally mounted on the mounting plate 17th is attached. This pivot lever 21 is in its axis of rotation with a rigid, vertically downwardly directed shaft 22 connected by means of a torsion spring 28th is curious. At the lower end of the shaft 22, a lever 23 is centrally mounted on the movement of the drawbar 20 via the pivot lever 21 and the shaft 22nd is transmitted. At the two ends of the lever 23 are arranged horizontally Coupling rods 24 and 25 articulated, on the rotational movements of the lever 23 in linear movements are transformed. The staggered to each other Coupling rods 24 and 25 extend, as shown in FIGS. 1 and 2, into the region of outer closing edges of the door frame, are bent at their ends downwards and at the top of the car body rotatably mounted, triangular Swivel plates 26, 27 coupled. At the third pivot point of the pivot plates 26 or 27, the respective locking bars 14 are hinged, over which the Movement of the locking bracket 13 is triggered.

In the closed state of the door leaves 1a, 1b, these are also at the two outer closing edges locked. The rotary latch 12 are in engagement with the arranged on the inside of the door leaves rollers 9 and the locking bracket 13th are due to the force acting on this spring force of the tension springs 13i down pulled, the rollers 13f are located immediately in front of the locking portion 12b of the rotary latch 12. The mounted on the mounting plate 17 pivot lever 21 is held by the torsion spring 28 in the locked position.

The unlocking is initiated by the door opening command. The with commissioning The drive motor energy generated by the DC motor 6a is through the bevel gear 6b, 6c, the toothed belt transmission and the pivot gears 4a, 4b on the the racks 1a, 1b attached racks 3a, 3b transferred. The swivel gearbox 4a, 4b produce in conjunction with the outwardly bent portion of the Racks 3a, 3b a counter to the locking force, a blocking, due to the locked door leaves. Due to this blocking is on the DC motor generates a reaction torque, whereby the housing of the motor 6 a to the drive shaft turns. This rotational movement is on the segment plate 18 on the Pull rod 20 and the pivot lever 21 counterclockwise rotated, overcoming the applied spring force. The rotational movement of the Swing lever 21 is transmitted via the vertical shaft 22 to the lever 23, through its rotational movement in the counterclockwise direction hinged to this Coupling rods 24 and 25 perform a linear pulling movement and thereby on the Swing plates 26 and 27, the respective vertical locking bars fourteenth be raised and the locking bracket 13 about its axis of rotation 13b upwards pivot and release the rotary latch 12 or its locking portion 12b. With the now released blockage for the movement of the door leaves 1a, 1b is about the combination swivel gear / rack and the drive energy of the Motors completed the transverse and subsequent longitudinal displacement of the door leaves. The rollers 9 are on the inside of the door disengaged from the clockwise direction, by the applied spring force to the stop 11c rotating Turnstile 12.

When closing the locking is done in reverse order, the locking movement primarily by the on the locking bracket thirteenth applied spring force is achieved.
