Figs. 1 to 4 illustrate a built-in non-vehicle easily Darge pivot sliding door as well as the device for its movement in a first embodiment. It is first of all based on FIG. 1, the basic structure of the pivoting sliding door, which also applies to the other embodiments, is explained. The door leaf 1 is verbun via a swivel arm 2 with a support member 4 designed as a slide, which is guided on a guide rail 3, which is configured as a rail and runs horizontally in the vehicle longitudinal direction. Furthermore, a control roller 33 is arranged on an auxiliary arm 34 connected to the swivel arm 2 , which engages in a guide rail 32 which is fixedly connected to the door frame 15 and which is curved inwards at one end. The driving device of the door has an electric motor 18, whose output member 18 a via a timing belt 18 b to the input member 19a of a reduction gear 19 is connected, the output of element 19 b a tes along the Führungselemen 3 guided circulating toothed belt 19 c drives the at the the Reduction gear 19 opposite the end runs over a guide roller 19 d. The support member 4 is connected via a connecting element c 4 a toothed belt with the nineteenth

For further guidance and for pivoting the door leaf 1 , a arranged on the door frame 15 , rotatably mounted, vertically standing door tree tube 5 is seen before, on which a first roller lever 9 is arranged in the upper region of the door leaf, which via a guide roller 9 a in a on the door leaf arranged horizontally extending guide rail 6 engages. In the lower area of the door panel 1, an analog roller lever 10 is arranged on the jamb tube 5, which via a guide roller 10 a in a corresponding leaf to the door 1 arranged guide rail 7 (see Fig. 4).

In the illustrated embodiments, the reduction gear 19 is designed and angeord net that the axis of its output element 19 b is tical. The housing of the reduction gear 19 is rotatably mounted in a manner not shown on the door frame about an axis of rotation which runs coaxially to the axis of the output element 19 b. Furthermore, a first gear 20 a is arranged on the housing of the reduction gear 19 coaxially to the axis of rotation, which engages in a second gear 20 b, to which a coupling rod 28 is fastened, which is connected in an articulated manner to a swivel arm 29 arranged fixedly on the door tree tube 5 ( Fig. 4).

On the door leaf 1 runs immediately below the obe ren guide rail 6 and parallel to this another guide rail 8 (see Fig. 4), in which a second guide roller 11 engages, which on the roller lever 9 at a horizontal distance from the guide roller 9 a at a bend of the roller lever 9 is arranged, as can be seen from FIGS. 2 and 3. The additional guide rail 8 has at its end facing the door tube 5 an inwardly guided Endab section 8 a, which is open at the front, so that, as can be seen from FIGS. 2 and 3, the guide roller 11 during the closing movement in this end section 8 a enters and exits.

The operation of the device for moving the pivoting sliding door presented with reference to FIGS . 1 to 4 is as follows:

In the closed state of the door leaf 1 shown in FIGS. 1 and 2, the roller lever 9 is guided inwards and the additional guide roller 11 emerges from the end section 8 a of the additional guide rail 8 . The coupling rod 28 is, as can be seen in FIG. 2, in a door position tube 5 and the door leaf 1 locking dead position. This means that the door leaf 1 cannot be easily moved in the transverse direction, for example by pressing from the inside. To initiate the opening movement, the electric motor 18 of the Antriebsvorrich device is switched on, whereby gear 19 via the reduction gear 19 and the toothed belt 19 c, the support member 4 is set in motion in the longitudinal direction. By occurring at the housing of the reduction gear 19 reac tion force in the drive movement is transmitted to the Ge housing a torque exerted by which the Ge housing at the beginning of the opening movement in the depicting lung according to Fig. Twisting 2 in the direction of arrow A1 in a clockwise direction. This rotary movement of the gear 20 a is transferred to the gear 20 b (arrow direction A2), the coupling rod 28 being carried along and being guided out of the dead center. The roller lever 9 is pivoted outwards and with it the front edge of the door leaf 1 . In the course of the onset of longitudinal movement, the additional guide roll 11 can enter the end section 8 a of the additional guide rail 8 , so that finally in the fully pivoted out state, as can be seen from FIG. 3, the rolls 9 a and 11 are at a horizontal distance Longitudinal direction in the upper guide rail 6 or the additional guide rail 8 are located, which has the consequence that the rotary movement of the door tube 5 is blocked. This ensures that with the pure longitudinal movement of the door leaf 1, the exact guidance in its movement level is maintained. This is done in the closed tung Rich until the end of the closing movement by the entry of the additional guide roller 11 in the curved end portion 8a of the guide rail 8, the blocking is released. Finally, due to the torque generated by the corresponding reaction force on the housing of the reduction gear 19 and the corresponding rotation of the gear wheels 20 a and 20 b, the coupling rod 28 and with it the door boom tube 5 and the roller lever 9 are returned to the position shown in FIG. 2 gets into wel cher the coupling rod 28 in the already explained dead center position and locks the door leaf 1 in the closed position.

A somewhat different embodiment of the device for moving the pivoting sliding door is explained below with reference to FIGS. 5 to 7. Here, in FIGS. 5 to 7 only the pivot sliding door is in the region of Darge Türbaumroh res exploiting Dende portion having changes with respect to the execution form of FIG. 2 to 4. Components of the Implementing approximate shape according to FIGS. 5 through 7, which correspond precisely to the components of the embodiment of FIG. 2 to 4, characterized by a '. The connection of the door panel 1 through the pivoting arm 2 to the displaceable on the guide member 3 supporting member 4 and the guide of the support member 4 on the guide rail 32 are formed as shown in FIG. 1. Similarly, the drive of the door movement the elec tromotor 18, the reduction gear 19 and the tooth belt 19 c analogous to FIG. 1 formed. The transmission of the reaction force of the drive from the housing of the reduction gear 19 is in turn carried out via a gear transmission 20 a 'and 20 b', with a gear 30 being arranged on the gear 20 b 'with which the pivot arm 29 ' on the door boom tube 5 'An acting coupling rod 28 ' is connected. The leadership of the door leaf 1 'in the region of the door tube 5 ' it follows the upper roller lever 9 ', the Füh approximately roller 9 a' in the door leaf 1 'arranged upper guide rail 6 ' engages. In an analogous manner, the door leaf 1 'is supported in the lower area via the lower roller lever, not shown.

In this embodiment, the additional Liche guide rail does not extend over the entire length of the upper guide rail 6 ', but is designed as a short rail piece 16 , which is arranged at the front end in the opening direction of the upper guide rail 6 ' directly after this and guided inwards is. The blocking of the rotation of the door boom tube is carried out in this embodiment via a two-armed lever 12 a- 12 b, the fulcrum at the outer end of the upper roller lever 9 ', wherein one arm 12 a of the lever, a guide roller 17 and the other lever arm 12 b Guide roller 31 carries. As can be seen in FIG. 5, the arrangement is such that in the pivoted-in state of the door tree tube 5 'and door leaf 1 ', the guide roller 17 is retracted into the rail piece 16 , while the guide roller 31 is within an opening 6 a '( FIG. 5 and 7) the upper guide rail 6 '. The guide roller 31 supporting arm 12 b of the two-armed pivot lever bil det, as can be seen from FIGS. 5 and 6, together with the upper roller lever 9 ', a one-armed pivot lever 13 arranged on the door boom tube and one connecting the two pivot levers 12 b and 13 Coupling rod 14 , a quadrilateral joint. The arrangement is such that the two pivot levers 12 b and 13 thereby form a pair of parallelogram links. At the end of the rocking lever 13 there is an extension with a guide roller 13 a, which is on the cam disc 30 at.

The operation of the illustrated in FIGS . 5 to 7 Darge embodiment of the device for moving the pivoting sliding door is as follows:

In the closed illustrated in Fig. 5 to stand the door panel 1 'is in turn the coupling rod 28' in a dead center position, so that the door leaf is locked in this position 1 and can not be moved by pushing to the outside. When the drive is switched on, the gear 20 b 'moves in the direction of the arrow A2' as a result of the reaction force, whereby the coupling rod 28 'is taken along and the roller lever 9 ' is pivoted outwards. Here, the four-bar linkage is taken along and in this first movement step a small longitudinal movement of the door leaf 1 'is already effected.

With the gear 20 b ', the cam plate 30 a rotates until the disposed on the extension of the pivot lever 13 guide roller 13 a finally in a groove 30 on the cam 30 engages and the parallelogram b out 12 and 13 inward. In this position, the roller lever 9 'is fully pivoted and the door tube 5 ' is in the end position of its rotation. By engaging in the groove 30 a control roller 13 a, the four-bar linkage is blocked (see Fig. 6) and thus the door tree tube 5 'locked against rotation. The control roller 17 runs from the rail section 16 into the guide rail 6 ', which has the result that, as can be seen from Fig. 6, the guide roller 31 emerges from the opening 6 a' and on the outside of the upper guide rail 6 'along runs, whereby the guide roller 13 a is fixed in the groove 30 a. By guiding the two-armed lever 12 a- 12 b with the guide rollers 17 and 31 , the door leaf 1 'is precisely guided at this point in its plane of movement, while it is moved in the longitudinal direction to the full opening width.

In the closing movement of the Füh is approximately role by entering 17 in the rail section 16 and entspre and fair pivoting of the pivot lever 12 b and 13 the lock is released and by the onset of the end of the closing movement reaction force via the gear train 20 A '20 b', the coupling rod 28 ' 5 leads back into the locked position shown in FIG .

Since in the course of the opening movement of the door leaf 1 or 1 ', the distance between the door arm 1 leading in the region of the trailing edge pivot arm 2 and the coupled with the door tube 5 guide devices becomes smaller, it may be appropriate to provide additional guidance of the door leaf 1 to provide, which is effective in the fully pivoted state during the longitudinal movement. Such an additional guide is shown below with reference to FIGS . 8 and 9, in which the pivoting sliding door in the area of the trailing edge of the door leaf 1 is shown in the closed state and in the pivoted-out state at the start of the longitudinal movement.

This additional guide device has a Ge quadrilateral, the extended from its pivot point on the support member 4 beyond the pivot arm 2 , a portion of the door panel 1 in the longitudinal direction, a link connected to the pivot arm extension 2 a 24 and a link 24 connecting the handlebar with the door leaf 1 Coupling member 26 is constructed. The Ge steering points are designated by reference numerals 21 , 22 , 25 and 23 . At the articulation point 25 is a Ver lock-out element 25 in a form of an elongated Bol zen and the support member 4 an end piece is arranged with a groove 27 a 27th In the first phase of the opening movement when swinging out is pivoted about the engaging into the guide rail 32 guide roller 33 at the end connected to the pivot arm 2 guide arm 34 of the pivot arm 2, and as shown in FIGS. Refer 8 and 9, the arrangement of the Ge is directing quadrangle made so that in the final phase of the pivoting movement, the locking element 25 a runs into the guide groove 27 a.

As a result, the four-bar linkage is fixed in its position and the door leaf 1 is supported against rotation via the four-bar linkage at the pivot points 21 and 23 .
