In 1 is a manually operated sliding door system 10 shown. The sliding door system 10 essentially comprises a suspension 200 , at least one sliding door 11 is suspended. The suspension 200 preferably has a base profile 201 on, by means of a fastening screw 203 when in 1 shown example on a wall 12 is appropriate. At the base profile 201 is a profile 202 fixed in place. The profile 202 has a roller section or a guide rail 208 on, on or the rollers 207 roll. On the rollers 207 is a sliding door 11 attached.

The rollers 207 can by means of a mounting stop or a holder on the sliding door 11 to be appropriate. But you can also, as in 1 shown in a carriage 206 integrated, in turn, on the sliding door 11 is fixed in place. Furthermore, the profile has 202 a brush holder 209 on, in the brushes 204 are included. The free ends of the brushes 204 ie the brush holder 209 remote ends of the brushes 204 , point towards sliding door 11 and are attached to this. This provides effective protection against pollution. In a ground area 14 is the sliding door 11 in a guided tour 15 taken, causing a tipping out of the sliding door 11 out the sliding door suspension 200 is prevented.

To the sliding door system 10 to be provided with a motor drive, is a suspension 300 according to a first embodiment of the invention, as in 1B shown, provided.

The suspension 300 has a profile 301 on. When retrofitting, the profile 202 according to 1A against the profile 301 replaced.

The profile 301 preferably has an intermediate wall section 318 on. The partition wall section 318 shares the profile 301 in two areas.

The in 1B to the left of the intermediate wall section 318 lying area of the profile 301 is like that in 1A shown profile 202 shaped and thus set up to perform the same functions as the profile 202 , For example, the profile has 301 analogous to the profile 202 a roller section or a guide rail 317 on, on the rollers 207 from sliding doors 11 are stored rolling.

The in 1B right of the partition wall section 318 lying area of the profile 301 serves to accommodate all parts of a drive 303 ie all parts that are required, the sliding door 11 to move. This is between the intermediate wall section 318 and one parallel to it, in the z-coordinate direction in 1B at a predetermined distance arranged side wall portion 319 a receiving section 328 created in the form of a cavity. The partition wall section 318 , the side wall section 319 and possibly one connecting the two wall portions of the upper wall portion are towards the cavity for receiving the parts of the drive 303 shaped accordingly. Ie. the parts of a drive 300 are by means of inside wall sections of the receiving portion 328 held.

According to 1B is the drive 303 formed as a linear drive by means of a linear motor. The linear motor comprises a rotor 320 which preferably consists of a magnetizable or magnetic material and by means of rotor rollers 322 In profile 301 stored stored recorded. The linear motor further comprises a stator, not shown, which preferably consists of an arrangement of electric coils. The stator preferably extends over an entire travel length of the sliding door to be moved 11 and is in profile 301 above the runner 320 arranged.

So that the sliding door 11 by means of the drive 303 moved, ie can be moved, is at a bottom of the rotor 320 a driver part 304 appropriate. Alternatively, the driver part 304 Part of the runner 320 itself and is moved due to an alternating magnetic field generated in the stator itself.

The driver part 304 is arranged so that it is away from the runner 320 substantially horizontally, ie in -z coordinate direction in 1B , to the sliding door 11 extends. The driver part 304 undermines the partition wall section 318 of the profile 301 , Ie. the driver part 304 extends below the partition wall section 318 and at least in the area located below the partition wall section 318 is in the y-coordinate direction to this one predetermined, preferably slight distance. The driver part 304 points at one end to the sliding door 11 facing, a driver section 305 on. The driver section 305 stands, as in 1B indicated with a carriage 206 in active connection. This causes a movement of the driver part 304 in at least one direction of travel ± x a movement of the sliding door 11 in the same direction.

The sidewall section 319 is on the outside, ie in the z-coordinate direction and / or in the -y coordinate direction, preferably designed so that a cover 302 attachable. Preferably, the side wall portion 319 Rastauf took 323 or resting sections 324 , preferably in the form of latching projections, on. The cover 302 points in the places that the locking shots 323 or rest sections 324 opposite, latching sections 324 or snap shots 323 on, so the cover 302 on the profile 301 can be clipped and also easily removed again. The arrangement of snap-shots 323 and resting sections 324 leads to a locking of the cover 302 in the Einklips state. The resting sections 323 and snap shots 324 can also be configured as retaining projections.

The cover 302 is preferably designed so that it not only the profile 301 in the z-coordinate direction but also the driver part 304 in -y coordinate direction and preferably also optically hidden towards the sides in the ± x coordinate direction. This causes the parts of the suspension 300 not visible from the outside.

The cover 302 extends as in 1B shown in the attachment state, preferably from an upper edge of the profile 301 along the side wall 319 , "Kinks" below the sidewall section 319 in the direction of the sliding door 11 then preferably extends to a sliding door 11 out there, that's the sliding door 11 facing the end of the cover 302 to the sliding door 11 has a predetermined, preferably small distance.

Around the interior of the suspension 300 Protecting against dirt is on the cover 302 preferably a brush arrangement similar to that in Figs 1A shown suspension 200 intended. As in particular in 1C To recognize this is at one end of the cover 302 , the sliding door 11 facing, extending in the x-coordinate direction brush holder 325 designed, leading to the sliding door 11 is open. In the brush holder 325 are brushes 326 so taken up that they are sliding towards the door 11 extend. The free ends of the brushes 326 lie on the sliding door 11 which creates protection against pollution.

Alternatively, other protection mechanisms may be provided. For example, instead of the brushes 326 find a foam insert use.

In 2A to 2J are different versions of active connections between driver part 304 and carriages 206 shown.

In 2A is a sliding door carriage 206 shown in perspective view. The carriage 206 preferably has a device for jamming with a sliding door 11 and a height adjustment. Furthermore, the carriage 206 castors 207 on the in 1B illustrated guide rail 317 of the profile 301 freely rotatable and guided are stored. In addition, the carriage 206 preferably a substantially C-shaped profile viewed in the x-coordinate direction 211 on.

2A further shows an operative connection between driver part 304 and carriages 206 according to a first embodiment of the invention. At the bottom of the carriage 206 are in the y-coordinate direction threaded taps 307 educated. At the driver section 305 has the driver part 304 in the y-coordinate direction extending through holes 308 whose number equals the number of tapped holes 307 is. The passage openings are formed so that they are in a state in which the profile 301 including drive 303 and driver part 304 is mounted, with the threaded holes 307 are arranged in alignment. From a bottom of the driver section 305 here are fixing screws 306 through the passage openings 308 going through screwed into the threaded holes.

Should the driver part 304 in the assembled state to the bottom of the profile 211 have a distance, as in right 2A are shown, are between driver part 304 and profile 211 Spacers preferably in the form of spacers 327 arranged, which bridge this distance. The spacers can with the driver part 304 be formed integrally.

2 B shows an operative connection between driver part 304 and carriages 206 according to a second embodiment of the invention. In this case, preferably one of the side surfaces of the carriage in the z-coordinate direction 206 used as a stop surface. The operative connection comprises a stop member 329 ,

The stop part 329 points in a driver part 304 facing area a mounting portion 332 on. In the attachment section 332 are in the y-coordinate direction threaded taps 307 educated.

In the driver section 305 of the driver part 304 are passage openings in the y-coordinate direction 308 educated. From one of the attachment section 332 opposite side of the driver section 305 here are fixing screws 306 through the passage openings 308 going through in the threaded holes 307 screwed. The stop part 329 beats at a movement in -x coordinate direction to the carriage 206 and take it with you. Ie. the stopper part 329 comes with an actuation of the on drive 303 on the side surface of the profile 211 for lying, the drive direction of the drive 303 turned away. The stop part 329 thus pushes the carriage 206 in the drive direction, in 2 B case shown in -x coordinate direction.

This embodiment is particularly suitable for sliding door systems that already have a mechanical, mostly spring-based sliding door opening system or sliding door locking system. Through such a system is on the carriage 206 one against a drive direction of the drive 303 directed force exercised. This is the stop part 329 always on the carriage 206 at. An impact and related shocks and possible damage are thus avoided.

If no such mechanical sliding door opening system or sliding door locking system is present, this embodiment can be used in particular in the cases in which the carriage 206 in the area where the stopper part 329 strikes, made of magnetizable material. The stop part 329 is made in the case of magnetic material, so it is constantly on the carriage 206 at. As a result, striking and related shocks and possible damage are avoided.

The magnetic force of the stopper is sufficient 329 out, the drive can 301 the sliding door (s) 11 drive in both directions of travel. In particular, when operating heavy sliding doors is the stopper 329 preferably formed by means of a high-performance magnet, preferably rare earth high-performance magnet. The rare earth high performance magnet is preferably made of neodymium-iron-boron (NeFeB) or samarium-cobalt (Sm ₂ Co) or plastic-bonded magnet materials.

An advantage of the second embodiment over the first embodiment is that the carriage 206 No processing is necessary, which simplifies retrofitting and eliminates possible sources of errors during assembly.

If magnetic material can not be used, according to an in 2C shown third embodiment of the invention instead of a unilaterally acting stop member 329 one on the carriage 206 attacking stop on both sides 329 intended.

The stop part 329 has a recording room 331 preferably complementary to the shape of the part of the carriage 206 is formed, the part of the stop 329 should be included and thus be embraced.

The receiving space is preferred 331 by means of a profile which is substantially U-shaped in cross-section in the z-coordinate direction 310 educated. The U is in the direction of the carriage 206 open.

The stop part 329 is from below on the carriage 206 pushed, wherein the two, extending in the y-coordinate side legs of the carriage 206 embrace. The legs preferably have a distance to each other, which is substantially a dimension of the carriage 206 in the x-coordinate direction. As a result, the legs to the carriage 206 in a Umgreif-position no or only a very small distance, so that when changing a Verfahrrrichtung by the drive 303 no striking of one of the legs on the carriage 206 he follows. Shocks and possible damage are thus avoided.

The stop part 329 has horizontal, ie seen parallel to an xz plane at a bottom threaded holes 307 which extend in the y-coordinate direction. The driver section 305 of the driver part 304 has appropriately trained passage openings 308 on. By means of fastening screws 306 be driver part 304 and stopper part 329 attached to each other.

This embodiment may be modified such that the U does not move upwards in the y-coordinate direction but in -z-coordinate direction in the direction of the sliding door 11 is open. Ie. In this case, the stopper part is pushed from the drive view from the front. This is especially for an operative connection with a driver of a multi-leaf sliding door system 10 suitable.

The driver part 304 is with the driver section 305 on a driver section 305 ' of the driver part 304 ' plugged, whereby both driver parts 304 . 304 ' engage each other. The elastically deformable insert allows a particularly good fixation of the driver part 304 ' in the driver part 304 , Furthermore, certain movements of the driver part 304 ' be damped to some extent, so that they at least not to the same extent on the driver part 304 and thus on the runner 320 impact. The driver section 305 has an insertion opening, which is preferably formed continuously. This is a screwing or unscrewing of the driver 304 '' out possible if the driver part 304 is plugged.

According to a in 2I illustrated ninth embodiment of the invention is in the driver part 304 instead of a substantially circular insertion opening, a slot-shaped insertion opening is provided, which is preferably transverse to a direction of movement of the carriage 206 , ie in the ± z coordinate direction in 2I is formed extending. Instead of an elastic insert a sliding bearing can be provided. Advantageously, the slide bearing is formed by means of an insert made of slip-resistant material, preferably plastic. This may cause the driver part 304 ' in the driver part 304 move freely in the area of the slot. Movements of the operatively connected trolley 206 or the associated driver part 304 ' at least in the ± z coordinate direction can thus be compensated or at least attenuated.
