Here is the traction means 20 over the two roles 21 . 22 guided. The traction device 20 forms a kind of endless loop. The traction device 20 can be designed as a closed loop for this purpose. In the illustrated embodiment, however, it is such that in the traction means 20 the sled 15 is switched so that the traction means 20 only in the broader sense forms an infinite loop.

The axes of rotation of the two rollers 21 . 22 are usually aligned parallel to each other. The axes of rotation of the two rollers are 21 . 22 preferably oriented vertically or horizontally.

The arrangement is now made such that the traction means 20 substantially parallel to the direction of sliding movement of the door panel 1 , ie parallel to the longitudinal axis 8th of the drive housing 3 , runs. The movement of the traction device 20 This can easily be used to move the door leaf 1 be used. This is the means of traction 20 with both ends 23 on the sledge 15 set so that the carriage 15 by means of the drive motor 4 over the traction means 20 is displaceable. In principle, it can also be provided that the traction means 20 only with one end 23 on the sledge 15 is fixed. Then there are additional measures for the return of the door leaf 1 provided.

The traction device 20 is on the one, in 4 right side 24 of the sled 15 on the sledge 15 passed, with the carriage 15 for this purpose, a corresponding recess 25 having. Furthermore, it is preferably such that the traction means 20 on the opposite, in 4 left side 26 of the sled 15 with his ends 23 on the sledge 15 is fixed and that the carriage 15 for this also corresponding recesses 25 having ( 2 ).

The above-described equipment of the carriage 15 with recesses 25 allows a particularly space-saving arrangement. In fact, the traction means is running 20 in a sense, by the sled 15 through, without claiming additional lateral space.

For the realization of the feed gear 6 Other variants are conceivable. For example, the feed gear 6 be designed as a spindle-spindle nut transmission. The sled 15 would be designed in this case as a spindle nut. Furthermore, it is conceivable, one with the door leaf 1 to provide a running electric motor, with a in or on the drive housing 3 arranged rack engages.

It was explained above that the special orientation of the drive motor 4 , so here is the arrangement of the drive shaft 7 parallel to the longitudinal axis 8th of the drive housing 3 has particular advantages in terms of achievable compactness of the arrangement. To this special arrangement of the drive motor 4 to ensure, is the intermediate gear 5 designed in a corresponding manner.

In the simplest case, the control device ensures 30 the motorized movement of the door leaf 1 via a fixed button. The control device 30 but can also have a flow control with integrated timer, so that an automatic motorized moving the door panel 1 is possible. This is in blackout devices, for example in the design of the door panel 1 as a shutter, beneficial. Finally, the control device 30 also have a radio module, so that the motorized movement of the door panel 1 via a radio remote control is possible. Here is also a data transfer with infrared or ultrasound conceivable.

It may also be advantageous, the control device 30 equipped with a solar cell assembly to at least the energy needs for the controller 30 , possibly also the drive motor 4 cover up.

The control device 30 may be further coupled with sensors such as light sensors, temperature sensors or proximity sensors, which is a corresponding motorized movement of the door panel 1 trigger. Again, it is particularly compact when the sensors are in the drive housing 3 are integrated. This also applies to the solar cell arrangement described above. The drive housing 3 may then have corresponding openings or transparent sections.

For the control technology recognition of the end positions of the door leaf 1 Different variants are conceivable. For example, the traction means 20 be equipped at predetermined locations with magnets, which are queried via a corresponding sensor, in particular a Hall sensor. It is also conceivable optical or mechanical query.

It may be noted that the pulley 21 preferably with a clamping device 31 is coupled with the position of the pulley 21 relative to the drive roller 22 is changeable. As a result, can be easily the optimum tension of the traction device 20 to adjust. The for the tensioning of the traction device 20 required clamping force is here via the drive housing 3 directed. In this case, the clamping device is supported 31 at the in 5 shown end of the drive housing 3 from. At the other end of the drive housing 3 is one with the intermediate gear 5 or the drive motor 4 coupled pin 32 provided, which via a corresponding bore in the drive housing 3 in turn ensures a support and at the same time acts as a security against rotation ( 3a ), b)).

The proposed solution is not on an arrangement with only a single door leaf 1 limited. It can be provided that a further, not shown door leaf is provided and, preferably, that a further, not shown carriage is provided, which via a further, not shown driver assembly with the other Door leaf is coupled drive technology. The other slide is in turn drive technology with the traction means 20 coupled.

The arrangement with two door leaves 1 is now preferably made so that upon actuation of the drive motor 4 the two door leaves 1 be moved in opposite directions. This can be realized that the one door leaf in the respective direction of the traction device 20 Seen at a point in front of the pulley 21 with the traction means 20 is coupled and that the further door leaf in the respective direction of traction means 20 seen at a point behind the pulley 21 with the traction means 20 is coupled. At the in 3b ), this would mean that the one door leaf with the in 3b ) Lower Zugmittelabschnitt is coupled and that the further door leaf with the in 3b ) Upper Zugmittelabschnitt is coupled. Since these two Zugmittelabschnitte move in opposite directions, also results in a corresponding opposite sliding movement of the door leaves. The coupling of the door leaves with the traction means 20 is preferably provided over the two carriages.

The Both door leaves can be basically in be designed to be displaceable on the same plane. It can be provided that at least one of the door leaves one Has fold, which covers the other door leaf slightly closed.

It but can also be provided that the two door leaves in different levels are displaced and thus together can be moved over. This can be advantageous in certain applications.

Basically, the with two door leaves a lock arrangement be designed over the the two door leaves against each other are lockable. The castle arrangement let yourself preferably open electrically.
