Description

The invention relates to a retrofit kit for a sliding door and a sliding door system.

From the DE 198 42 567 A1 is a manually operated double-leaf sliding door system known. The sliding door system is based on a belt drive. An endless belt is guided around two pulleys. The endless belt is operatively connected via a driver with one of the sliding doors. Furthermore, a drive unit is provided, which has an outwardly projecting output shaft. The output shaft and one of the pulleys are designed so that the output shaft when attaching the drive unit to this pulley with her in rotational engagement.

It is not clear how the drive unit is to be attached to the sliding door system. In addition, the drive unit is not in single-leaf sliding door systems and sliding door systems that do not have a pulley, usable.

From the DE 88 00 862 U1 a sliding door system is known in which a sliding door can be provided with a drive. The drive is based on a friction mechanism. The sliding door has a friction surface on an upper edge for this purpose. Alternatively, a drive rail is provided above the sliding door, which has a friction surface. The sliding door is connected to each other stationary with the drive rail. The sliding door or the drive rail with the friction surface is arranged below a ceiling rail. In the case of a drive rail, this is attached to the ceiling rail. Friction wheels are arranged pressing against the respective friction surface. The pressure effect can be achieved by means of preloaded springs. The drive motor for the friction wheels is also attached to the ceiling rail and drives the friction wheels pressing against the sliding door. The drive motor is arranged outside a suspension for the sliding door, ie in front of or behind the suspension, with respect to a walking direction.

This type of drives is not suitable for sliding door systems that are not mounted on a ceiling but on a building wall. In addition, the sliding doors are to be provided with a friction surface or to attach a drive rail to the respective sliding door.

The object of the invention is therefore to provide a universal drive, by means of which in particular manually operated sliding doors of almost any kind can be retrofitted cost and easily with a motor drive.

The object is solved by the subject matter of patent claim 1. Advantageous developments are specified in the subclaims.

According to the invention the object is achieved by means of a retrofit kit for at least one sliding door. When retrofitting the at least one sliding door of the retrofit kit is attached to a suspension of the sliding door. The sliding door is mounted rolling on a guide rail of this suspension by means of single rollers or carriages. Alternatively, the sliding door can also be suspended and guided by means of magnetic force. The retrofit kit also has a suspension. In this second suspension a drive for the sliding door is added. When retrofitting the drive is connected to a holder of a single role, with a carriage, with a driver or with the at least one sliding door itself. The holder, the carriage or the driver are each operatively connected to the at least one sliding door. By connecting the drive with one of the described parts of the drive is able to move the at least one sliding door

In multi-leaf sliding door systems, the sliding doors are typically operatively connected to one another via one or more traction means. The sliding doors are operatively connected by means of a driver with the one or more traction means. In this type of sliding door systems according to the invention alternatively provided to connect the drive with one of the drivers in the manner described.

The solutions described above offer the advantage that the drive can be mounted regardless of the way the sliding door is mounted. The coupling of the drive is done with existing parts of the suspension itself.

Alternatively, the invention provides for the drive to be effectively connected to the sliding door itself. This offers an even higher versatility, since also sliding door systems can be retrofitted, where there are no single rollers or carriages. This is the case, for example, with purely magnetically held sliding doors.

An inventive retrofit kit preferably has a profile which is adapted to receive the necessary parts for driving a sliding door. According to the invention, the profile can be fixedly attached to an already existing profile of a suspension of the sliding door to be automated. This ensures that in a sliding door system, where the each sliding door is attached, as many parts of the suspension continue to be used as possible, which helps to reduce the cost of retrofitting.

The attachment of the profile according to the invention is preferably carried out by means of a screw fastening.

Alternatively, it is provided to attach a mounting plate, for example by means of a screw to the existing profile of the sliding door system. The inventive profile including drive is then hung instead of the profile of the suspension of the sliding door in the mounting plate or inserted and locked to it. The locking can be done by means of turn a now accessible screw or by means of a locking mechanism 'preferably by means of Einklipsens. This has the advantage that the profile with inserted drive is possible even if the otherwise provided fastening screws for the profile are difficult to access.

Alternatively, it is provided to design the profile according to the invention such that it is simply exchanged for the profile of the suspension of the sliding door. Ie. the profile according to the invention is designed in a region for a suspension of the respective sliding door; it is shaped in the area as the existing profile of the sliding door system. In a region other than the area for the suspension of the sliding door, the profile for receiving a drive is formed. The advantage is that apart from the existing profile of the sliding door suspension, all other parts of the existing sliding door system continue to be used. Furthermore, the existing mounting options are used; new ones are not required. This facilitates retrofitting. There must be no holes with a prescribed accuracy drilled into the profile of the suspension and possibly threaded into it, which simplifies assembly.

The drive is coupled according to the invention with a driver part, which is the connection to the suspension of the sliding door, d. H. to a single roll holder, a carriage, a driver or the sliding door itself, manufactures. The driver part may be part of the drive or be formed separately.

According to the invention a cover is additionally providable, which is preferably clipped to the profile according to the invention and the profile down and forward and to the sides, d. H. away from the sliding door and thus visually obscured to the outside. In addition, a protection against contamination may be provided, as it is also used in conventional sliding door systems.

According to the invention, this protection is effected by means of a brush arrangement which is attached to the cover and is arranged in the direction of the sliding door.

Further features and advantages of the invention will become apparent from the following description of preferred embodiments.

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

The rollers 207 may be attached by means of a mounting stop or a holder on the sliding door 11. But you can also, as in FIG. 1 shown to be integrated in a carriage 206, which in turn is fixedly mounted on the sliding door 11. Furthermore, the Profile 202, a brush holder 209, are received in the brush 204. The free ends of the brushes 204, ie the ends of the brushes 204 facing away from the brush holder 209, point in the direction of the sliding door 11 and rest on it. This provides effective protection against pollution. In a bottom region 14, the sliding door 11 is received in a guide 15, whereby a tilting out of the sliding door 11 from the sliding door suspension 200 is prevented.

In order to provide the sliding door system 10 with a motor drive, a suspension 300 according to a first embodiment of the invention, as in FIG. 1B shown, provided.

The suspension 300 has a profile 301. When retrofitting the profile 202 according to Figure 1A replaced with the profile 301.

The profile 301 preferably has an intermediate wall section 318. The intermediate wall portion 318 divides the profile 301 into two areas.

The in FIG. 1B To the left of the intermediate wall portion 318 lying portion of the profile 301 is like that in Figure 1A formed profile 202 and thus configured to perform the same functions as the profile 202. For example, the profile 301 analogous to the profile 202 a roller portion or a guide rail 317, are mounted on the rollers 207 of sliding doors 11 rolling.

The in FIG. 1B To the right of the intermediate wall section 318 lying portion of the profile 301 serves to accommodate all parts of a drive 303, ie all parts that are required to move the sliding door 11. For this purpose is between the intermediate wall portion 318 and a parallel to him, in the z-coordinate direction in FIG. 1B arranged at a predetermined distance Sidewall portion 319 created a receiving portion 328 in the form of a cavity. The intermediate wall section 318, the side wall section 319 and optionally an upper wall section connecting the two wall sections are correspondingly shaped towards the cavity for receiving the parts of the drive 303. Ie. the parts of a drive 300 are held by means of inside wall sections of the receiving section 328.

According to FIG. 1B the drive 303 is 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 is stored guided by means of rotor rollers 322 guided in the profile 301. 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 11 to be moved and is arranged in the profile 301 above the rotor 320.

Thus, the sliding door 11 moves by means of the drive 303, d. H. can be moved, a driver part 304 is attached to a bottom of the rotor 320. Alternatively, the driver part 304 is part of the rotor 320 itself and is itself moved due to an alternating magnetic field generated in the stator.

The driver part 304 is arranged so that it is substantially horizontally from the rotor 320, ie in the -z coordinate direction in FIG. 1B extending to the sliding door 11. The driver member 304 thereby undermines the intermediate wall portion 318 of the profile 301. D. h. the driver part 304 extends below the intermediate wall section 318 and has at least in the region which is below the intermediate wall section 318 is in the y-coordinate direction to this a predetermined, preferably slight distance. The driver part 304 has at one end, which faces the sliding door 11, a driver portion 305. The driver portion 305 stands, as in FIG. 1B indicated, with a carriage 206 in operative connection. As a result, a movement of the driver part 304 in at least one travel direction ± x causes a movement of the sliding door 11 in the same direction.

The side wall portion 319 is outside, d. H. in the z-coordinate direction and / or in the -y coordinate direction, preferably designed so that a cover 302 can be attached. The side wall section 319 preferably has latch receptacles 323 or latching sections 324, preferably in the form of latching projections. The cover 302 has at the locations opposite the latching receptacles 323 or locking portions 324, latching portions 324 and latching receptacles 323, so that the cover 302 can be clipped onto the profile 301 and also easily removed again. The arrangement of locking receptacles 323 and latching portions 324 leads to a locking of the cover 302 in the clip-in state. The latching sections 323 and latching receptacles 324 can also be designed as holding projections.

The cover 302 is preferably designed to optically conceal not only the profile 301 in the z-coordinate direction but also the cam member 304 in the -y coordinate direction and preferably also towards the sides in the ± x coordinate direction. As a result, the parts of the suspension 300 are no longer visible from the outside.

The cover 302 extends as in FIG FIG. 1B shown in the attachment state preferably from an upper edge of the profile 301 along the side wall 319, "kinks" below the side wall portion 319 in the direction Sliding door 11 and then preferably extends to a sliding door 11 out that the sliding door 11 facing the end of the cover 302 to the sliding door 11 has a predetermined, preferably small distance.

To protect the interior of the suspension 300 from dirt, the cover 302 preferably has a brush arrangement similar to that in FIG Figure 1A shown suspension 200 is provided. As in particular in Figure 1C For this purpose, at one end of the cover 302, which faces the sliding door 11, a brush receptacle 325 extending in the x-coordinate direction is formed, which is open towards the sliding door 11. Brushes 326 are received in brush receptacle 325 so that they extend in the direction of sliding door 11. The free ends of the brushes 326 abut the sliding door 11, thus providing protection against contamination.

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

In FIGS. 2A to 2J Different versions of active connections between driver part 304 and carriage 206 are shown.

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

FIG. 2A further shows an operative connection between driver part 304 and carriage 206 according to a first embodiment of the invention. On an underside of the carriage 206 threaded holes 307 are formed extending in the y-coordinate direction. At the driver portion 305, the driver member 304 in the y-coordinate direction extending through holes 308, the number of which is equal to the number of threaded holes 307. The through holes are formed so as to be aligned with the tapped holes 307 in a state where the profile 301 including the driver 303 and the dog member 304 is mounted. From an underside of the driver section 305, fastening screws 306 are screwed through the through openings 308 into the threaded bores.

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

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

The stop part 329 has a fastening section 332 in a region facing the driver part 304. In the attachment section 332, threaded bores 307 are formed extending in the y-coordinate direction.

In the driver portion 305 of the driver 304 304 extending through openings 308 are formed in the y-coordinate direction. From a side facing away from the mounting portion 332 of the driver portion 305 forth fastening screws 306 are screwed through the through holes 308 passing into the threaded holes 307. The abutment part 329 strikes against the carriage 206 during a movement in the -x coordinate direction and takes it along. Ie. the stop member 329 comes to lie on actuation of the drive 303 on the side surface of the profile 211, which is remote from the drive direction of the drive 303. The stop member 329 thus pushes the carriage 206 in the drive direction, in FIG. 2B 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. By means of such a system, a force directed against a drive direction of the drive 303 is exerted on the carriage 206. As a result, the stop member 329 is always on the carriage 206. An impact and related shocks and possible damage are thus avoided.

If there is no such mechanical sliding door opening system or sliding door locking system, this embodiment can be used in particular in cases where the carriage 206 in the Area in which the stop member 329 strike, made of magnetizable material. The stop member 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.

If the magnetic force of the abutment part 329 is sufficient, the drive 301 can drive the sliding door or doors 11 in both directions of travel. In particular, when operating heavy sliding doors, the stop member 329 is 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 no machining is necessary on the carriage 206, which simplifies the retrofitting and eliminates possible sources of error during assembly.

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

The stop member 329 has a receiving space 331, which is preferably complementary to the shape of the part of the carriage 206, which is to be received by the stop member 329 and to be encompassed therewith.

Preferably, the receiving space 331 is formed by means of a profile which is substantially U-shaped in cross section in the z-coordinate direction. The U is designed to be open in the direction of carriage 206. The stop member 329 is pushed from below onto the carriage 206, wherein the two, in the y-coordinate direction extending side legs engage around the carriage 206. The legs preferably have a distance from each other which is substantially equal to a dimension of the carriage 206 in the x-coordinate direction. As a result, the legs to the carriage 206 in a gripping position no or only a very small distance, so that when changing a Verfahrrrichtung by the drive 303 no striking one of the legs on the carriage 206 takes place. Shocks and possible damage are thus avoided.

The stop member 329 has horizontally, d. H. Parallel to an x-z plane seen on a bottom threaded holes 307 extending in the y-coordinate direction. The driver section 305 of the driver part 304 has correspondingly formed through openings 308. By means of fastening screws 306 driver part 304 and stop member 329 are fastened together.

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

According to a fourth embodiment of the invention is provided, the driver part 304 and the carriage 206, as in FIG. 2D shown with to provide a Velcro connection 309. On, seen horizontally, a bottom of the carriage 206 or at an upper side of the driving portion 305, a hook tape or a mushroom tape is preferably attached by gluing. Accordingly, a fleece band, a suede band or a mushroom band, for example, is likewise adhesively attached to the upper side of the driver portion 305 or to the underside of the carriage 206.

An in the first embodiment with respect to FIG. 2A described distance between the underside of the carriage 206 and driver portion 305 is preferably bridged by the fact that the driver portion 305 in the direction of the carriage 206 toward a larger extent has, that is made thicker.

The fourth embodiment is particularly suitable for sliding door systems 10, in which no great effort for driving the respective sliding door 11 is required. This is the case, for example, with lightweight sliding doors 11.

According to a fifth embodiment of the invention is a stop member 329, as in Figure 2E shown horizontally in the x-coordinate direction, preferably formed as a profile with the shape of an inverted U. The legs of the U-shaped profile extend with their free ends in the direction of the sliding door eleventh

The stop member 329 preferably has a length which is equal to the distance between two immediately adjacent carriages 206, on which one and the same sliding door 11 is suspended. The stop member 329 thus abuts the mutually facing side surfaces of these two carriages 206 and can safely take the sliding door 11.

Preferably, the distance between the free ends of the legs of the abutment part 329 is preferably a little smaller than a depth dimension of the sliding door 11 in this area, i. H. whose dimensions are horizontal, d. H. in an x-z plane, in the z-coordinate direction. When placing the stop member 329 on the sliding door 11, it jams on the sliding door 11 and is thus securely held or locked.

The clamping force of the stop member 329 may be so large that it alone is sufficient that the stop member 329 can take the sliding door. In that case, the length of the abutment part 329 may be less than the distance between the two immediately adjacent carriages 206 on which one and the same sliding door 11 is suspended.

In addition, a clamping device may be provided on the stop member 329, as they are used, for example, in suspension devices in which, for example, frameless glass sliding doors are hung without mounting holes.

On a side surface of the abutment part 329 facing the drive 303, the abutment part 329 has a preferably centrally arranged attachment section 332. The fastening section 332 preferably has an L-shaped cross-sectional shape, viewed horizontally in the x-coordinate direction, that is to say L points in the direction of the drive 303, ie in the z-coordinate direction. On an underside of the attachment portion 332 extending in the y-coordinate direction threaded holes 307 are formed. The driver portion 305 of the driver 304 has passage openings 308, which are formed analogously to the embodiments already described. Driver member 304 and mounting portion 332 are secured together by means of fastening screws 306.

If the sliding door 11 itself is workable, according to a sixth embodiment of the invention, the stopper member 329 is preferably formed as in FIG Figure 2F shown. The stop member 329 has two attachment portions 330, 332.

The attachment portion 330 is formed so that it preferably rests on the top of a sliding door 11 in an area where there is no carriage 206 and a roller 207, respectively. In the attachment portion 330, there are preferably provided two through holes 308 extending from an upper surface of the attachment portion 330 in -y coordinate direction Figure 2F extend toward the top of the sliding door 11. In the sliding door 11 threaded bores 307 are formed, which are arranged so that in each case a through hole 308 is aligned with a threaded bore 307. From the top of the mounting portion 330 in FIG Figure 2F Fastening screws 306 are screwed through the passage openings 308 into the threaded bores 307.

The fixing portion 332 is formed to be in accordance with Figure 2F preferably rests on the top of a driver portion 305 of the driver 304. In the attachment portion 332, two threaded bores 307 are preferably provided, which extend in the direction of the driver part 304. The driver portion 305 has through holes 308, which are arranged so that in each case a through hole 308 is aligned with a threaded bore 307. From the underside of the driver 305 in Figure 2F Fastening screws 306 are screwed through the passage openings 308 into the threaded bores 307.

An operative connection according to a seventh embodiment of the invention differs from the described sixth embodiment in the design and attachment of the abutment member 329 to a sliding door 11. As in FIG FIG. 2G illustrated, the stop member 329 has a mounting portion 332, which is formed as in the operative connection according to the sixth embodiment of the invention. Further, the stopper member 329 has a fixing portion 330 which is formed so that the stopper member 329 in -z coordinate direction can be fastened to a sliding door 11. Preferably, at least two threaded holes 307 are formed in the sliding door 11, which in z coordinate direction in FIG. 2G extend. In the same direction extending passage openings 308 are formed in the attachment portion 330. From the front of the attachment portion 333 in FIG. 2G Fastening screws 306 are screwed through the passage openings 308 into the threaded bores 307.

In the embodiments described above, the stop member 329 and the driver member 304 may also be integrally formed. In that case, the respective threaded holes 307, through holes 308 and fixing screws 306 are omitted.

At an in FIG. 2H shown active connection according to an eighth embodiment of the invention, the driver portion 305 of the driver 304 has an insertion, which preferably by means of a in FIG. 2H hatched represented, elastically deformable insert is provided. Further, a second driver part 304 'is provided which is fixedly attached to a respective carriage 206, for example by means of screwing. For this purpose, the driver part 304 'at one end facing the carriage 206 on a projecting towards the carriage 206 threaded portion. For screwing in the driver part 304 'at a portion between the threaded portion and driver portion 305' a non-circular outer contour, preferably in the form of an external hexagon. As a result, the driver part 304 'can be screwed into the carriage 206 by means of a wrench.

During assembly, the second driver part 304 'is first screwed into the carriage 206. The driver member 304 is fitted with the driver portion 305 on a driver portion 305 'of the driver 304', whereby both driver parts 304, 304 'engage with 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 304' can be damped to some extent so that they do not affect the driver member 304 and thus the rotor 320 at least to the same extent , The driver portion 305 has an insertion opening, which is preferably formed continuously. As a result, a screwing or unscrewing of the driver part 304 "from possible when the driver part 304 is attached.

According to a in Figure 2I illustrated ninth embodiment of the invention, a slot-shaped insertion opening is provided in the driver part 304 instead of a substantially circular insertion opening, which preferably transverse to a direction of movement of the carriage 206, ie in the ± z-coordinate direction in Figure 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. As a result, the driver part 304 'in the driver part 304 can move freely in the region of the oblong hole. Movements of the operatively connected carriage 206 or the associated driver part 304 'at least in the ± z-coordinate direction can thus be compensated or at least dampened.

In Figure 2J an operative connection according to a tenth embodiment of the invention is shown.

On a side facing away from the rollers 207 in the z-coordinate direction of the base profile 201, a cover 205 is arranged on this.

As in FIG. 5B shown, the suspension 300 is designed in this case so that a profile 301 is formed from an intermediate wall portion 318 in the direction of sliding door 11 again as the profile 202 to be replaced. On the opposite side of the intermediate wall portion 318, that is, in the z-coordinate direction side in FIG. 5B , the profile 301 is formed as in the first embodiment. The suspension 300 can thus be provided with all embodiments of active connections described above.

FIG. 6A shows the sliding door system 10 of FIG. 5A , wherein in addition a side part 16 is present. The side part 16 is received at the top in a suspension 200. Below the side part 16 is held or stored in a side member receptacle 17. Unlike the in FIG. 5A Sliding door system 10 shown between profile 202 and base profile 201 instead of a cover 205, an intermediate piece 210 is arranged. The intermediate piece 210 separates a sliding door suspension portion of the suspension 200 from a side member receiving portion of the suspension 200. On the profile 202, on a side facing away from the sliding door 11, a cover portion is formed which optically conceals the upper portion of the side member 16 outwardly.

As in FIG. 6B In this case, the suspension 300 is in turn designed such that a profile 301 is formed from an intermediate wall section 318 in the direction of the sliding door 11 as the profile 202 to be replaced. On the opposite side of the intermediate wall portion 318, the profile 301 is formed as in the first embodiment.

In a suspension 300 for a sliding door 11 according to a fourth embodiment of the invention is therefore, as in FIG. 7C shown, additionally provided a mounting plate 336. The mounting plate 336 is configured to be fixedly attached to the profile 202 of an existing suspension 200. Preferably, the mounting plate 336 has a through hole 308 like the profile 301 according to the third embodiment described above. Thus, the mounting plate 336 can be fastened by means of fastening screws 306 on the profile 202.

On the side facing the profile 301, the mounting plate 336 preferably has latching receptacles 337 and / or latching sections 338 at the top and bottom, similar to the latching receptacles 337 and latching projections 338 in the profile 301 with respect to the in FIG. 7A illustrated suspension part 339. On the side facing the mounting plate 336, the profile 301 has correspondingly above and below detent recesses 337 and latching sections 338. This makes it possible to mount or insert and profile the profile 301 into the mounting plate 336 and furthermore preferably to lock it by means of latching.

The through-holes 308 described herein are preferably countersunk on the side from which a fastening screw 306 is inserted, so countersunk screws can be used and screwed flush.

Instead of the described threaded bores 212, 307, passage openings 213, 308 are also possible, as space permits, as shown below, for example FIG. 7B shown. In this case, the respective fastening screw 306 is arranged to pass through the passage openings 213, 308 and at the other end to be screwed to a nut 214.

Instead of a screw fastening all other known non-positive and / or positive fastenings such as welding or gluing are possible, insofar as the stability criteria are met.

Although the embodiments have been described with a particular type of carriage 206, they are of course applicable to any other type of carriage, as far as the operating principle of the respective embodiment is possible.

In addition, the described embodiments are also suitable for sliding doors 11, which are mounted instead of carriage 206 by means of individual rollers 207. Each single roll 207 is typically operatively connected to the respective sliding door 11 via a downwardly facing support. The seen in the direction of travel front and rear surfaces of the holder can be used in each case as a stop surface.

With a retrofit kit according to one of the embodiments described above, a sliding door with any type of drives can be retrofitted; Retrofitting is independent of the type of suspension of the respective sliding door (s).

For sliding doors in which the guide rail is mounted directly on a wall, it is provided that the profile of the retrofit kit according to the embodiments described above is designed so that it can be fixed to a wall or ceiling. This can be done by the retrofit kit also has a wall or ceiling mounting stop for the profile. This makes it possible to continue to use the existing guide rail.

The embodiments have been described with respect to a respective sliding door. The embodiments are each directly operatively connected to a carriage, a single roller holder, a driver or a sliding door.

Thus, they can also be used in multi-leaf sliding door systems.

In the case of multi-leaf sliding door systems whose sliding doors are moved independently of each other, it is provided that each individual sliding door can be retrofitted with its own retrofit kit. In the case of a plurality of retrofit sets arranged next to one another in the direction of access, provision can be made for the covers 302 to be connected to one another or to be replaced by a single cover 302 covering all profiles 301.

In a linear drive by means of a linear motor, a separate rotor can alternatively be provided for each sliding door. The coils of the stator, which are responsible for a runner at a given moment, must be appropriately controlled in order to move the sliding doors as desired.

In the case of a traction mechanism drive, as with manually operated, multi-leaf sliding door systems, several traction parts can be provided on the traction means. This makes it possible with a retrofit kit, for example to operate two sliding doors in opposite traversing directions or in the same traversing direction.

In a spindle drive several spindles can be provided. For example, if two sliding doors are to be moved in the same direction, only two spindles with drivers are to be attached to the spindle drive and each operatively connected to a sliding door. If, in this example, the two sliding doors are to be moved in opposite directions, a pitch of the threaded spindle in the respective direction of travel is formed on the spindle for each travel of the respective sliding door. Ie. the gradients for the two sliding doors point in opposite directions.

Sliding door systems in which several sliding doors are operatively connected to each other, for example, multi-leaf sliding door systems and telescopic sliding door systems. These sliding door systems have in common that the sliding doors are usually operatively connected to each other via a cable system and / or a transmission gear, so that the movement of a sliding door causes a predetermined movement of the other sliding door (s). The sliding doors are typically each operatively connected by means of a driver with the traction means of the cable system, such as a rope or pull strap, or with the transmission gear. Instead of a carriage or a single roll holder, the retrofit kit can be operatively connected to one of the drivers.

Although the retrofitting of a manually operated sliding door system has been described, it is of course possible to retrofit already automated, ie provided with a motor drive sliding door systems. Such a case can occur when the power of the previously used drive is no longer sufficient, since for example the sliding doors to be moved with higher speed and / or acceleration.

If the resulting two drives are to continue to be used, a corresponding synchronization and / or switching control circuit must be provided, by means of which the operation of both drives is coordinated.
