In the illustrated embodiment, the drive an electric motor 25 and one operatively connected to it stationary gear 26 for driving wheels 18 of a carriage 12 of each wall element 10. As a result of the frictional Contact of the wheels 18 with the mounting rail 19 can Carriage 12 and the surface element 11 associated therewith Operation of the drive 24 can be moved.

The mounting rail 19 has a box-shaped profile. Your lower wall is divided approximately in the middle by one Longitudinal slot 27 extending in the longitudinal direction of the mounting rail 19. The longitudinal slot 27 is in a facing the surface element 11 Area of the mounting rail 19 arranged, namely in the lower horizontal wall. For lateral guidance of the carriage 12 and the surface element 11 is at least one Guide roller 28 is provided, for example, in the longitudinal slot 27 can pass on.

The supply of energy to the wall element 10 from an external Energy source can be done by means of the pantograph 29 that are assigned to each driven carriage 12 and in Active connection with a fixed conductor rail 30 in the ceiling area stand, namely glide along this.

In Fig. 3, a wall element 10 is shown, in which the Surface element 11 an upper sealing strip 31 and a lower one Sealing strip 32 has. By means of a drive 33, these can are moved relative to the surface element 11, namely in the direction of the floor 15 and / or extended towards the ceiling 16 and retracted. The drive 33 is via connecting lines from the pantographs 29 with electrical energy provided.

By means of the electric motor 36 with an upstream gear 37 can a spindle 38, on the one hand via a coupling with the Electric motor 36 or transmission 37 is connected, on the other hand is rotatably mounted in the counter bearing 39, preferably horizontally Alignment of the spindle.

A spindle nut 40 is arranged on the thread of the spindle 38, which when rotating the spindle 38 relative to the Spindle nut 40 is movable in the axial direction of the spindle 38. The spindle nut 40 is by two opposite levers 41 with two opposite on a common, upright Axle lying push rods 45, 46 connected. By horizontal Move movements of the spindle nut 40 on the spindle 38 which are articulated at their opposite ends on both the Spindle nut 40 and mounted on the push rod 45, 46 Lever 41 push rods 45, 46 simultaneously in opposite directions Senses either together or apart.

The push rods 45, 46 are mounted on their facing one another Ends can be moved in opposite directions the counter bearing 39 is arranged lying on an upright axis Slide bearing sleeves 42, 43. The lower push rod 46 is in this embodiment again formed variable in length. A lower area on the lower push rod 46 stored compression spring 48 holds this under tension in one maximum extended state. Through this training the lower Push rod 46 is achieved in spite of tolerance Irregularities in the actuation mechanics both the top Sealing strip 31 and the lower sealing strip 32 completely against the floor and ceiling of the room to be subdivided can be extended because, for example, when already the lower sealing strip 32 completely on the floor is present, both push rods 45, 46 moved further apart can be until the upper sealing strip 31 is completely on of the ceiling, namely by the lower push rod 46 pushes against the bias of the compression spring 48, so shortened.

Another embodiment for the design of the Drive for moving the sealing elements is shown in Fig. 4. Here is a surface element 11 with a frame 13 as well as a glass wall 14 surrounded by the same. in the An actuating mechanism 51 is arranged inside the frame 13. This has a pressure medium member 52, with which the position of the pressure cylinder 53 is changeable. The longitudinal axis of the pressure medium cylinder 53 is oriented vertically, namely in the direction of the longitudinal extension of the vertical Frame element 54. The pressure medium cylinder 53 is in its the end region facing the floor 15 with a push rod 55 connected, which passed through the frame in a bore 56 is. The one opposite the pressure cylinder 53 End region of the push rod 55 is also on the bearing point 57 a two-armed lever 58 connected. The one just trained here Lever 58 has two lever arms 59 of approximately the same length, 60. With one lying centrally between the lever arms 59, 60 horizontal axis of rotation 61, the two-armed lever 58 is pivotable hinged under the lower horizontal frame member 62. For this purpose, a lower horizontal frame element 62 is used vertically downward-pointing stud 63 connected on the freely movable one rotatable on the axis of rotation 61 of the two-armed Lever 58 arranged hinge piece 64 is attached.
