Description

[0001] The invention relates to a linear motor device for a sliding door system and a sliding door system with such a linear motor device.

[0002] Sliding door systems comprise at least one sliding door, which is often suspended from two tracks guided in a running rail. The running rail is either permanently mounted to a ceiling or wall using mounting screws, or detachably mounted to a mounting rail using a fixing device, which in turn is permanently mounted to a ceiling or wall.

[0003] Devices for connecting a sliding door, for example a sliding door with a wooden or glass panel, to a track are known from US6438795, US6418588B1, US6052867A, and US9341011B2. A linear motor device for a sliding door system, comprising a sliding door that can be moved along a track by means of two tracks, is known from US20100139172A1. This linear motor device comprises a stator part held in the track and rotor parts, each connected to a track.

[0004] EP3702569A1 discloses a linear motor device with a control arrangement located between two stator parts.

[0005] The construction of linear motors, which in their design correspond to an unwound electric motor, is known, for example, from US20090256428A1. US20090195195A1 discloses that Hall sensors can be used to determine the position of the rotor parts of the linear motor device.

[0006] EP2476842A2 discloses a sliding door system with two sliding doors, each held slidably by one or more carriages, and each associated with a drive device comprising a stationary stator assembly and a rotor assembly connected to the associated carriage. If the linear motor device has multiple carriages for each of the sliding doors, these can be moved and flexibly adjusted to the width of the associated sliding door, which is selected according to the width of the door opening to be closed. If, however, only one carriage is provided for each of the sliding doors, this must be provided according to the width of the sliding door, provided that no restriction of the sliding door's travel is permissible.

[0007] The present invention is therefore based on the objective of providing an improved linear motor device for sliding door systems that have at least one sliding door.

[0008] The linear motor device should be integrable into sliding door systems with simple measures, which have one or more sliding doors with different dimensions.

[0009] Sliding doors, for example sliding doors with a wooden panel or a glass panel, should be easy to install regardless of the existing mounting devices.

[0010] The sliding doors should be easy to install even if the track runs into a door recess, such as a wall pocket, and there is little space available for installing the sliding door.

[0011] The linear motor device should have a simply designed operating device that takes up little space and is easy to operate.

[0012] This problem is solved with a linear motor device for a sliding door system according to claim 1 and a sliding door system according to claim 13. Advantageous embodiments of the invention are specified in further claims.

[0013] The linear motor device, which is intended for a sliding door arrangement with at least one sliding door, comprises at least one stator part arranged in a guide rail and at least one drive unit slidably held in the guide rail. which has running elements mounted in the running rail, which can be connected to the associated sliding door by means of mounting devices, and which comprises a running gear body and a runner part, which runner part carries a plurality of individual runner magnets facing the stator part.

[0014] According to the invention, it is provided that that the running gear is modular in design and its length can be adapted to the dimensions of the associated sliding door; that the running gear body is modular and has at least two running gear body modules, at least one of which is detachable from the running gear; that the runner part is modular and has at least two runner modules, at least one of which is detachable from the running gear; that the length of one or more of the detachable running gear body modules corresponds to the length of one or more of the detachable runner modules; and that connecting means are provided by means of which the at least one detachable running gear body module and the at least one detachable runner module can be connected to the running gear.

[0015] The modular drive unit can therefore be configured according to the length of the sliding door it is intended to support. For example, the modular drive unit is supplied according to the maximum width of a sliding door that a user might use. If the user wishes to install a narrower sliding door in the sliding door system, they can shorten the drive unit by removing one or more drive unit body modules and one or more runner modules. The removed drive unit body module(s) will each be the same length as the removed runner module(s).

[0016] The length of the at least one detachable drive body module and the length of the at least one detachable runner module are preferably equal, or preferably in an integer ratio to each other, or have a common multiple. The drive body modules and / or the runner modules can be provided with a uniform length or with different lengths.

[0017] Corresponding drive body modules and runner modules can be designed in any way, for example, connected to each other or separated from each other.

[0018] Preferably, the length of the one detachable drive body module or of all detachable drive body modules corresponds exactly to the length of the one detachable runner module or of all detachable runner modules.

[0019] In a first preferred embodiment, the at least one detachable drive body module and the at least one detachable runner module form a unit and thus a complete drive module with a drive body module and a runner module (see Fig. 8b ) and can be connected to or detached from the drive as a unit.

[0020] In further preferred embodiments, the at least one detachable drive body module and the at least one detachable runner module can be connected to or detached from the drive independently of one another. This embodiment has the advantage that the detachable drive body modules and the detachable runner modules can be selectively connected to one another and arranged in particularly advantageous positions. Furthermore, it offers the advantage that the drive body modules, on the one hand, and the runner modules, on the other, can each be connected to one another by particularly advantageous connecting means. The drive body modules can advantageously be connected to one another by screw connections, while the runner modules can advantageously be connected to one another by positive-locking connections with complementary form elements.

[0021] When assembling the drive, the drive body modules are connected first, followed by the runner modules, or vice versa. The drive body modules and the runner modules can be connected alternately.

[0022] In preferred embodiments, the runner part is positively connected or positively connected and slidably connected to the running gear body. The runner part preferably comprises a modular coupling rail which is positively connected, slidably, and lockably held in an anchor profile of the running gear body. In this particularly advantageous embodiment, the modular running gear body, optionally with pre-separated running gear body modules, and the modular runner part, optionally with pre-separated runner modules, mutually support each other. This significantly simplifies the manipulation of the running gear body modules and the runner modules. Since the running gear body modules are held by the coupling rail, the screw connections between the running gear body modules can be easily loosened and tightened.

[0023] In preferred embodiments, the coupling rail has a double-T profile and the running gear body has an anchor profile in which the coupling rail is axially displaceable. If the runner modules can be positively connected to one another by a movement that is not parallel to the longitudinal axis of the running gear, the connected runner modules are held permanently apart within the anchor profile. Only after the runner modules have been pulled out of the anchor profile can they be separated perpendicular to the longitudinal axis of the running gear and from each other. The connection of the runner modules is preferably achieved by mutually complementary form elements that can be positively engaged either inclined or perpendicular to the longitudinal axis of the running gear.

[0024] Preferably, the coupling rail comprises a support plate, an intermediate plate with reduced width, and an anchor plate, forming a double-T profile which, due to the reduced width of the intermediate plate, has a retaining groove on both sides. The support plate, located outside the drive body, carries the runner magnets, and the anchor plate is slidably and lockably held within the anchor profile of the drive body. The anchor profile preferably encloses a T-profile-shaped opening suitable for the positive-locking reception of the anchor plate.

[0025] The carrier plate, the intermediate plate and the anchor plate can be joined together in one piece and only virtually separated from each other, and can, for example, be manufactured from a single workpiece.

[0026] Particularly advantageous is the support plate, which is preferably made of metal or plastic, the intermediate plate, which is preferably made of metal or plastic, and the anchor plate, which is preferably made of metal or plastic, provided as individual elements, for example each stamped from a sheet metal piece or produced by an extrusion process and joined together, for example, by means of a positive locking mechanism, screws or an adhesive.

[0027] In preferred embodiments, the coupling rail, preferably the anchor plate, has at least one tapered section at which the at least one detachable drive unit module can be decoupled from or coupled to the coupling rail. One or more tapered sections can be provided at any point along the coupling rail or along the anchor plate. If, for example, a tapered section is provided in the middle of the anchor plate, a drive unit module can therefore be decoupled from the anchor plate at this point. Subsequently, at least one of the drive unit modules adjacent to the resulting gap is moved against the other drive unit module to close the gap. As the remaining drive unit modules are pushed against each other, an end piece of the rotor section protrudes from the anchor profile on one side of the drive unit.Therefore, detachable runner modules are preferably provided at an end piece of the runner part or the coupling rail, so that they can be easily separated.

[0028] One or more detachable drive body modules are thus preferably arranged between two drive body modules that are not intended to be detached from the drive and can be connected, for example, to the associated sliding door by means of the mounting devices. The detachable drive body modules are therefore preferably not located at one or both ends of the drive body, but rather between two drive body modules that preferably remain permanently connected to the drive.

[0029] The drive body modules, which normally remain attached to the drive, are only replaced if different mounting devices are used and these necessitate the replacement.

[0030] To connect the individual drive unit modules, the modular drive unit has a mounting channel on the side facing away from the runner section, which preferably extends through all drive unit modules. The mounting channel is designed to accommodate the connecting elements by which the drive unit modules can be joined together. Furthermore, mounting elements, such as mounting plates, can be inserted into the mounting channel; these are used, for example, to connect the mounting devices by which the drive unit is connected to the associated sliding door.

[0031] The connecting means by which the drive body modules and / or the runner modules can be connected to each other can be designed as desired and preferably include complementary shaped elements and / or screw connections and / or locking elements.

[0032] Preferably, the drive body modules are connected to each other by screw connections, which, for example, have a tab that engages on both sides with adjacent drive body modules and can be fixed there by screws. The connecting means can also include snap-fit ​​elements that allow the drive body modules to be assembled particularly easily. For example, instead of a short tab that can engage with adjacent drive body modules (see Fig. 8a ), and is screwed in there, a longer tab should be provided that overlaps several or all detachable drive body modules and is connected to the overlapped drive body modules by screws and / or complementary grids, such as sawtooth shapes or triangular shapes that interlock with each other.

[0033] In further preferred embodiments, locking tongues are provided which are, for example, firmly connected to a drive body part and engage with the adjacent drive body part, locking automatically there. The drive body part can therefore be separated by releasing the locking tongue.

[0034] In further preferred embodiments, the mounting devices each comprise at least one connecting element, such as a rod, plate, or threaded rod, which is provided for connecting the running gear to the sliding door, and at least one of the connecting elements is slidably or slidably and lockably held by the running gear body. The opening through which the connecting element is inserted into the running gear body module can therefore be round, square, or an elongated longitudinal perforation.

[0035] In a preferred embodiment, the guide rail comprises two side pieces connected by a head piece. These side pieces have opposing running webs at their ends furthest from the head piece and opposing retaining webs between the running webs and the head piece. The at least one running gear is held in a track with its running elements between the running webs and the retaining webs. The at least one stator section is held in a stator channel between the retaining webs and the head piece and comprises one or more groups of stator magnets facing the track channel and a control device with at least one control button and optionally at least one control indicator. The number of stator magnets or stator coils can be chosen arbitrarily. Preferably, two groups of stator magnets are provided, each comprising six stator magnets.

[0036] The walkways and support rails have running surfaces for the running elements, with the first running elements resting on the upper side of the walkways and the second running elements resting on the underside of the support rails. The length of the walkways and support rails is preferably selected according to the width of the running elements. A control channel is provided between the facing front surfaces of the walkways and support rails, into which the user can reach to operate the control buttons.

[0037] The control buttons are preferably arranged parallel to the central axis of the track so that they can be easily operated when the sliding mechanism is retracted. Alternatively, the control device can be operated by remote control, optionally via a mobile device. The sliding door assembly is preferably integrated into a smart home system, which allows the user to control various devices, such as the sliding door system, automatic roller shutters, lighting fixtures, electrical and electronic equipment, and the like.

[0038] In further preferred embodiments, several stator sections or several groups of stator magnets are arranged in the guide rail or within the stator channel, and these can be individually controlled. The drive unit can therefore be automatically moved along the guide rail over any desired length by arranging the stator sections in such a way that the drive unit enters the influence area of ​​a second stator section before leaving the influence area of ​​a first stator section. It is therefore not necessary to arrange the stator magnets in a continuous series. Instead, individual groups of stator magnets can be provided, separated from each other by significant distances. The gap between two stator sections is preferably somewhat smaller than the length of the drive unit.

[0039] The linear motor device according to the invention allows for the realization of any sliding door arrangement, comprising one or more sliding doors, each slidably mounted along a track. The at least one track can be directly connected to a building component, such as a wall or ceiling, or coupled to a mounting rail, which in turn is connected to a building component and, for example, has an L-profile or a U-profile. The track, optionally held by a mounting rail, can run along the front of a wall or into a door recess. If the sliding door can be retracted into a door recess, it is advantageous if the connecting element of at least one of the mounting devices is slidably mounted on the drive mechanism.During installation, the sliding door can be connected to a first mounting bracket on one side and partially inserted into the door frame. The sliding door is then connected to the track using the second, movable mounting bracket. The movable nature of the connecting element facilitates, and in some cases even enables, the installation process.

[0040] Sliding doors can have panels made of glass, wood, or other materials. Wooden sliding doors are often provided with a recess at the top into which a retaining rail is inserted. The retaining rail serves to hold a mounting bracket that secures the connecting element. The mounting bracket is preferably connected to the track using the connecting screw before the sliding door is installed. The sliding mechanism of the connecting screw allows the mounting bracket to be inserted into the retaining rail and the sliding door to be connected to the track on this side as well. As described in the aforementioned prior art, a mounting bracket can also be inserted into or placed on top of the sliding door panel.

[0041] Auxiliary elements such as locking devices, closing devices, stop devices and the like can also be arranged in the running rail.

[0042] Furthermore, sensors such as Hall effect sensors, optical sensors, or electromagnetic sensors can be used to monitor and control the opening and closing process of the sliding door. For example, the control device can use a sensor to detect the movement of people and automatically open or close the sliding door. Additionally, the current supplied to the stator modules can be measured and monitored to detect any influences on the sliding door. Stop devices can limit the travel of the sliding door. Locking or closing devices can fix the sliding door in specific positions. Support devices can fix and lock the sliding door in selected positions, for example, after opening or closing.

[0043] Preferably, the sliding door can be moved along its track in increments by means of the control device, and these increments can be recorded in the control device. During a learning cycle, the number of completed increments is preferably recorded for specific positions of the sliding door. For example, the number of increments taken when moving the sliding door from one end stop to the other is checked. Subsequently, the sliding door can be controlled according to the specifications of the sliding door system. To compensate for tolerances, it is preferably provided that the stored number of increments for specified positions can be corrected. Preferably, the stator section comprises two groups of stator magnets with, for example, six stator coils each, which are controlled accordingly.

[0044] For example, the system determines the position at which the sliding door is flush with the side walls of the door frame. If there is a deviation, a correction menu can be accessed by pressing the control buttons on the control unit. This menu allows the number of steps to be adjusted for a programmed position. By pressing the control buttons again, the sliding door can be moved step by step to the exact position, after which the determined number of steps is saved. Therefore, stopping points can be defined along the travel path for any desired position.

The drawing shows: Fig. 1a a sliding door system 9 according to the invention with a schematically shown linear motor device 1, which comprises a stationary stator part 12 and a carriage 11 with a carriage body 111 and a runner part 112 and by means of which a sliding door 8 connected to the carriage 11 can be automatically moved into a door compartment 90 and extended again along a guide rail 2; Fig. 1b the sliding door system 9 of Fig. 1a after the partial opening of the sliding door 8; Fig. 1c the sliding door system 9 of Fig. 1b after the sliding door 8 is fully opened; Fig. 2a a part of the sliding door arrangement of Fig. 1c , with the sliding door 8, which is connected to the drive 11 of the linear motor device 1 by means of two mounting devices 7, which is slidably held in a running rail 2, which is coupled to a mounting rail 6; Fig. 2b the part of the sliding door arrangement of Fig. 2a without mounting rail 6 and with the guide rail 2, which is cut in such a way that the linear motor device 1 is exposed; Fig. 3 the mounting rail 6 of Fig. 2a with the guide rail 2 held therein; Fig. 3b the mounting rail 6 and the guide rail 2 separated from it of Fig. 3a with a stop device 25 taken from the running rail 2; Fig. 4 the running rail 2 of Fig. 3b with two side pieces 2B connected to each other by a head piece 2A, which have oppositely directed running boards 211 at the ends facing away from the head piece 2A and oppositely directed retaining boards 221 between the running boards 211 and the head piece 2A, and which laterally delimit the stator channel 22 and the running channel 21, and with an operating channel 28, which runs between the running boards 211 and the retaining boards 221 through the running channel 21 upwards into the stator channel 22; Fig. 4b the running rail 2 of Fig. 4a with attached coupling devices 5, with the stator part 12 inserted into the stator channel 22, and with the drive 11 inserted into the running channel 21, which has a drive body 111 that carries the rotor part 112 facing the stator channel 22 and which is connected to the sliding door 8 by a mounting device 7; Fig. 4c the running rail 2 equipped with the linear motor device 1 of Fig. 4b , which was coupled to the mounting rail 6 by means of the coupling devices 5; Fig. 5 the part of the sliding door arrangement of Fig. 2b (excluding the guide rail 2) with the running gear 11, which extends slightly beyond the entire width of the sliding door 8 and which comprises a modular runner section 112 and a modular running gear body 111; Fig. 6 shows the running gear 11 of Fig. 5 Exploded view from the front; Fig. 6 leg part of the drive 11 of Fig. 6a in spatial representation; Fig. 7 shows the modular runner part 112 of the drive 11 of Fig. 5 ; Fig. 7b the drive 11 of Fig. 5 during the removal of a drive body module 111B; Fig. 7c the drive 11 after removal of the drive body module 111B and subsequent sliding together of the remaining drive modules 111A, 111B, 111C, 111D and separation of a corresponding runner module 112B; Fig. 8a a part of the runner part 112 with two drive body modules 111B, one of which is shown in sectional view; Fig. 8 a drive module 11B, which has a drive body module 111B and a runner module 112B, which together form a unit that can be separated from a correspondingly designed drive 11; Fig. 9 the assembly device 7 of Fig. 4c ; Fig. 9 leg mounting device 7 for a sliding door 8 which includes a glass plate; Fig. 10 the underside of the stator part 12 of Fig. 5 with a housing 120 and covers 128A, 128B, between which two groups of six stator magnets 121A, 121B each are arranged, which are designed as electromagnets and comprise at least one coil; and Fig. 10b the stator part 12 of Fig. 10a after removing the covers 128A, 128B, looking at the power supply device 124 and the control device 122.

[0047] A door pocket, for example a wall pocket, is bounded on one or both sides by a wooden wall or masonry. Often the door pocket is bounded on one side by a wall and on the other by a wooden wall.

[0048] In this embodiment, the sliding door system 9 comprises only one sliding door 8, which can be moved between the front 9F and the rear 9R of the sliding door system 9 in order to close off a door opening 900 as required, which is limited on one side by a front element 93 and on the other side by the front sides of the door compartment walls 91, 92 of the door compartment 90.

[0049] Fig. 1b The sliding door system 9 of Fig. 1a after partially opening the sliding door 8. Fig. 1c The sliding door system 9 of Fig. 1b after the sliding door is fully opened 8.

[0050] The Figuren 1a, 1b und 1c The figures show that the stator part 12, which is short compared to the drive 11 and is symbolically represented by a black double arrow, is held stationary when the sliding door 8 is moved and always partially overlaps a part of the drive 11, which is symbolically represented by a white double arrow. A rectangle inserted into the white double arrow symbolizes that the rotor part 112 with a series of individual magnets is arranged on a drive body 111.

[0051] The drive unit 11, and thus the drive unit body 111 and the runner part 112, are modular in design, allowing the length of the drive unit 11 to be adapted to the width of the sliding door 8. The modularity of the drive unit 11, the drive unit body 111, and the runner part 112 can be implemented in various ways, as described in detail below.

[0052] The sliding door system 9 can be configured and dimensioned as desired. Shown is a sliding door system 9 with only one sliding door 8. However, the sliding door system 9 can also be equipped with multiple sliding doors. Furthermore, different tracks and mounting hardware for the tracks can be used. The track can be directly connected to a building component or coupled to a mounting rail, as described below.

[0053] Fig. 2a shows part of the sliding door arrangement of Fig. 1c The sliding door 8 is connected to the drive 11 of the linear motor device 1 by means of two mounting devices 7. The drive 11 is slidably held in a guide rail 2 (shown schematically by a dashed line). The linear motor device 1 is held within the guide rail 2 and is therefore not visible. The guide rail 2 is coupled to a mounting rail 6, which is connected to a building component by mounting screws 99. During the assembly of the sliding door system 9, the mounting rail 6 is pre-assembled so that the guide rail 2 can subsequently be coupled to the mounting rail 6 by means of coupling devices 5 and, if necessary, also decoupled again.

[0054] Fig. 2b shows part of the sliding door arrangement of Fig. 2a without the mounting rail 6 and with the guide rail 2, which is cut in such a way that the linear motor device 1 is exposed.

[0055] Fig. 3a The mounting rail 6 shows Fig. 2a with the guide rail 2 held therein. The mounting rail 6 comprises two side plates 62, which are connected to each other by a head plate 61. Spacer strips 63 are provided adjacent to the side plates 62, which maintain a clearance 630 between the building ceiling and the head plate 61. The head plate 61 has keyhole-shaped coupling openings 60 in which coupling devices 5 can be anchored. The coupling devices 5 comprise a coupling body 50, which is connected to the end piece 2A of the guide rail 2, and a coupling head 51, which is inserted into and held in the corresponding coupling opening 60.

[0056] Fig. 3b shows the mounting rail 6 and the separate running rail 2 of Fig. 3a , which has mounting openings 29 that serve for mounting the coupling devices 5. A dashed line shows that when the guide rail 2 is lifted, the coupling head 51 of the coupling device 5 is inserted into a larger opening part 601 of the coupling opening 60 and moved parallel to the longitudinal axis of the guide rail 2 and anchored in a smaller opening part 602 of the coupling opening 60.

[0057] Also shown is a stop device 25 taken from the guide rail 2, which comprises a mounting body 252 that can be fixed in a stator channel 22 of the guide rail 2 by means of a fixing screw 253 and which holds an end stop 251 that projects into a running channel 21 of the guide rail 2 and forms an end stop for the running gear 11 there.

[0058] Fig. 4a shows the running rail 2 of Fig. 3b with two side pieces 2B connected to each other by a head piece 2A, which have opposing walkways 211 at their ends facing away from the head piece 2A and opposing retaining webs 221 between the walkways 211 and the head piece 2A, and which laterally delimit the stator channel 22 and the running channel 21. Furthermore, an operating channel 28 is provided, which runs between the walkways 211 and the retaining webs 221 through the running channel 21 upwards into the stator channel 22.

[0059] Fig. 4b shows the running rail 2 of Fig. 4a with attached coupling devices 5, with the stator part 12 inserted into the stator channel 22, and with the drive unit 11 inserted into the running channel 21. The drive unit 11 has a drive body 111 which carries the rotor part 112 facing the stator channel 22 and which is connected to the sliding door 8 by a mounting device 7. Also shown is the hand of the user, who engages the operating channel 28 with the index finger to actuate the control device 122 of the stator part 12, in particular the control buttons 1221 (see Fig. 10a ).

[0060] Unless a remote control is provided, the linear motor device 1 can therefore be operated manually. The operating elements 1221 and display elements 1222 of the control device 122 are preferably arranged in a row (see Fig. 10a ), so that they are visible and easily accessible through the operating channel 28. Alternatively, the linear motor device can also be controlled contactlessly using sensors, for example motion sensors.

[0061] First running elements 1151 of the drive 11 rest on the running boards 211 of the guide rail 2 and bear the load of the sliding door 8. Second running elements 1152 of the drive 11 are shifted vertically upwards and lie against the underside of the retaining webs 221 if the drive 11 is lifted by magnetic interaction between the stator part 12 and the rotor part 112.

[0062] Fig. 4c shows the running rail 2 equipped with the linear motor device 1 of Fig. 4b , which was coupled to the mounting rail 6 by means of the coupling devices 5, the mounting rail 6 having previously been mounted to a building component G by means of mounting screws 99. The spacer strips 63 of the mounting rail 6 rest against the building component G, which is why a clearance 630 remains free between the building component G and the end plate 61 of the mounting rail 6. During the installation of the guide rail 2, the coupling head 51 was inserted through the coupling opening 60 in the end plate 61 of the mounting rail 6 (see Fig. 3b ) is inserted into the space 630 and then anchored in the coupling opening 60. After integration into the guide rail, the linear motor device 1 according to the invention can thus be mounted and dismounted from a ceiling particularly easily.

[0063] The drive unit 11 is connected to a sliding door 8, which comprises a wooden panel, by a connecting device 7, which includes a mounting body 71 and a connecting screw 72. A recess is provided in the top of the wooden panel, in which a retaining rail 70 is provided. The mounting body 71 is slidably and lockably held in the retaining rail 70. The connecting screw or threaded rod 72 is inserted into the drive unit 111 and held there in a thread of a mounting plate 114.

[0064] Fig. 5 shows part of the sliding door arrangement of Fig. 2b (without the guide rail 2) with the drive unit 11, which comprises the modular runner section 112 and the modular drive unit body 111. Runner magnets 1122 are seamlessly arranged one after the other on the runner section 112. In this preferred embodiment, the runner magnets 1122 are cuboid in shape. However, the runner magnets 1122 could also have a different shape, for example, a cylindrical shape. To adapt the drive unit 11 to a sliding door 8, modules of the drive unit 11 are selectively removed or added.

[0065] The drive body 111 comprises three detachable drive body modules 111B, 111C, which are held between two drive body modules 111A, 111D that are connected to the sliding door 8 by the connecting devices 7. Preferably, therefore, it is not the specially designed drive body modules 111A, 111D at the two ends of the drive 11 that are removed as needed, but rather one or more of the intermediate drive body modules 111B, 111C, which have no additional function.

[0066] The drive body modules 111A, 111B, 111C, and 111D are each assigned corresponding runner modules 112A, 112B, 112C, and 112D. Therefore, when changing the length of drive 11, one of the drive body modules 111A, 111B, 111C, or 111D and one corresponding runner module 112A, 112B, 112C, or 112D must be removed or added. In a first embodiment of the invention, the corresponding drive body modules 111A, 111B, 111C, 111D and runner modules 112A, 112B, 112C, 112D can be directly assigned to one another and form a corresponding drive module 11A, 11B, 11C, 11D, as shown in Fig. 5 This is illustrated. In a further preferred embodiment of the invention, the drive body modules 111A, 111B, 111C, 111D and the runner modules 112A, 112B, 112C, 112D are not directly spatially associated with each other. The detachable runner modules 112B, 112C are preferably arranged at one of the ends of the runner part 112, where they can be removed or added relatively easily.

[0067] It is evident that the drive mechanism 11 extends across the entire width of the sliding door 8 and projects approximately 5% to 10% of its length to the rear. The door compartment 90 should therefore preferably be dimensioned according to the length of the drive mechanism 11. This ensures that the rotor part 112 always remains in contact with the stator part 12 when the sliding door 8 is fully extended. In the illustrated embodiment, after the sliding door 8 has been fully extended, the drive mechanism part that projects beyond the sliding door 8 to the rear will be located below the stator magnets 121A, 121B of the stator part 12.

[0068] On the front side, the drive 11 is provided with a ring-shaped locking part 113, which, after reaching the end stop, is engaged and held by a locking device or closing device.

[0069] Fig. 6a Drive 11 shows Fig. 5 Exploded view from the front. The rotor section 112 was separated from the modular drive body 111 and divided into the cuboid rotor magnets 1122 and a modular coupling rail 1121. The coupling rail 1121 has a double-T profile and comprises a support plate 11211, an intermediate plate 11212 with reduced width, and an anchor plate 11213, which are preferably connected to each other by means of a screw 11219. In the area of ​​the intermediate plate 11212, the coupling rail 1121 has a retaining groove 11210 on both sides.

[0070] The drive body 111, of which the drive body module 111D is visible at the front, has a U-profile that includes two drive side pieces 111S, which are connected to each other by a drive center piece 111M. Between the drive side pieces 111S, the drive body 111 has a mounting profile 1111 adjacent to the drive center piece 111M and an anchor profile 1112 on the opposite side from the drive center piece 111M.

[0071] The anchor profile 1112 is designed to receive the anchor plate 11213 of the rotor section 112. The rotor modules 112A, 112B, 112C, 112D are thus held in the anchor profile 1112 and can be moved along it and locked, for example, by means of a fixing screw or clamping screw.

[0072] The mounting profile 1111, on the other hand, serves to accommodate connecting elements, such as those in Fig. 8a shown connecting tabs 1116 or other mounting elements, such as the mounting plate 114, which is screwed to the locking part 113 and to a connecting screw 72 of a mounting device 7 (see Fig. 9a ). On the front side of the drive mechanism center section 111M, a recess 1113 is also provided, which serves to receive the locking part 113.

[0073] Furthermore, running elements 1151, 1152 are shown, which are vertically displaced relative to each other. The running elements 1151, 1152 are designed as rollers and equipped with bearing shafts or wheel axles 11511, 11521.

[0074] Fig. 6b shows part of drive 11 of Fig. 6a in spatial representation. The running elements 1151, 1152 are vertically displaced relative to each other and are inserted into the bearing openings 11510, 11520 with the bearing shafts.

[0075] The rotor magnets 1122 are detached from the modular coupling rail 1121. Four short rotor modules 112B are connected to a long rotor module 112A. The rotor modules 112A and 112B are positively connected to each other by connecting elements 1126 and 1127. The connecting elements 1126 are armature-shaped, and the connecting elements 1127 are complementary to them. The rotor modules 112A and 112B are joined together serially, like puzzle pieces, and in their assembled state form the coupling rail 1121. Each individual rotor module 112B is connected to each other by two screws 11219.

[0076] Fig. 7a shows the modular runner part 112 of the drive 11 of Fig. 5 or Fig. 6b Four identical runner modules 112B were detached from a first runner module 112A and separated. The length of the runner modules 112B corresponds to the length of the identical drive body modules 111B. The length of two runner modules 112B corresponds to the length of the drive body module 111C. The length of all four runner modules 112B therefore corresponds to the length of the three drive body modules 111B, 111C, 111B, which have different lengths but are in an integer ratio to each other.

[0077] All runner modules 112A, 112B have the same features, with the runner module 112A and the runner modules 112B differing only in length and a special feature of the armature plate 11213.

[0078] The anchor plate 11213 of the long runner module 112A, which is not normally detached from the drive 11, preferably has at least one tapered section 112130 in the area of ​​one of the drive body modules 111A, 111D such that the anchor plate 11213 does not engage, or does not fully engage, in the anchor profile 1112 of the drive body 111 at this point. The length of the tapered section 112130 is dimensioned such that a detachable drive body module 112B, 112C can be moved up to this tapered section and detached from the anchor plate 11213. To shorten the drive body 111, the end-side drive body module 111A is detached from the coupling rail 1121 and moved to expose the taper 112130, after which the superfluous drive body module 111B is moved to the exposed taper 112130 and removed from the coupling rail 1121.

[0079] Fig. 7b Drive 11 shows Fig. 5 During the removal of one of the drive body modules 111B, the corresponding runner module 112B has not yet been removed. Therefore, the runner part 112 still contains all four runner modules 112B and must be shortened accordingly. A tab 1116 was removed along with the drive body module 111B. One of the tabs 1116 remains in the drive body 111 and serves to connect the now adjacent drive body parts 111A and 111C, which are to be slid against each other. When the remaining drive body modules 111A, 111C, 111B, and 111D are slid together, part of the runner part 112, i.e., the first runner module 112B, is pushed out of the anchor profile 1112 of the drive body 111 and is then detached from the adjacent runner module 111B.

[0080] The connecting elements 72 of the mounting devices 7 (see) are attached to the end-side drive body modules 111A, 111D. Fig. 9a ). It is shown by way of example that the connecting elements 72 are guided through elongated transfer openings 1110 (one transfer opening 1110 shown with a dashed line) of the drive body modules 111A, 111D and are each held in a mounting plate 114 (see Fig. 6b The connecting elements 72 and, if applicable, the associated mounting body 71 can therefore be displaced relative to the drive 11 and connected to the sliding door 8. It is normally sufficient to make only one of the connecting elements 72 displaceable to facilitate the installation of the sliding door 8. One of the transfer openings 1110 is therefore preferably provided as a longitudinal perforation, while the other transfer opening 1110 can be a circular hole. Depending on the design of the sliding door assembly 9, for example, when installing a glass door according to Fig. 9b The adjustability of the connecting elements 72 can also be completely dispensed with. In this case, both transfer openings 1110 are implemented as round perforations.

[0081] Fig. 7c Figure 11 shows drive 11 after the removal of drive body module 111B and the subsequent sliding of the remaining drive body modules 111A, 111B, 111C, and 111D together, and the separation of a corresponding runner module 112B. The now adjacent drive body modules 111A and 111C are connected by one of the tabs 1116 and two screws 1117. The removed drive body module 111B and the removed runner module 112B, which correspond to each other, are shown separately. The newly configured drive 111 now again has two connection levels. On the underside, the drive body modules 111A, 111C, 111B, and 111D are connected by the tabs 1116 and screws 1117. On the top side, the drive body modules 111A, 111C, 111B, 111D are connected to each other by the coupling rail 1121 with the anchor plate 11213, which is held in anchor profile 1112.This results in high stability of drive 111 in every possible configuration.

[0082] Fig. 8a Figure 1 shows a portion of the runner section 112 with two running gear modules 111B, one of which is shown in sectional view. The length of the running gear module 111B detached from the coupling rail 1121, i.e., from the anchor plate 11213, corresponds to the length of the taper 112130 in the anchor plate 11213. The sectional view shows that grooves are provided on both sides of the side plates 111S of the running gear section 111B, forming the mounting profile 1111 and the anchor profile 1112.

[0083] Fig. 8b Figure 11B shows a drive module comprising a drive body module 111B and a runner module 112B, which together form a unit that can be detached from the drive 11. The embodiments of Fig. 8a und Fig. 8b They can also be combined. For example, drive module 11B can be attached to one of the end pieces of drive 11. Fig. 7c to be attached.

[0084] Fig. 9a The mounting device 7 shows Fig. 4c , by means of which a sliding door 8, which has a wooden panel, is connected to a drive mechanism 111 according to the invention, for example according to Fig. 5 is connectable. How in relation to Fig. 4c As explained, the mounting body 71 is slidable in a retaining rail 70 and can be locked in place by means of a clamping screw 75. The retaining rail 70 is held in a recess 80 on the top side of the wooden panel of the sliding door 8.

[0085] The drive 11 was moved to an end stop and locked there by means of a locking device or locking mechanism 23. The locking device 23 comprises a mounting body 232, which is fixed in the stator channel 22 of the guide rail 2 by means of a fixing screw 233. The mounting body 232 holds an actuator 231, which has a retractable locking element or locking element 2311 that has been retracted into the locking part 113. The actuator 231 is preferably controlled by means of the control device 122 (see Fig. 10b ) or controllable via a remote control.

[0086] Fig. 9b Figure 1 shows a mounting device 7 for a sliding door 8, which includes a glass panel. Circular recesses 80 are provided on the top of the glass panel, into which plastic rings 78 are inserted. Furthermore, a mounting body 71 is provided with two mounting plates, which are connected to each other by transverse screws 77 that pass through the plastic rings 78. The connecting element 72 is located between the connected mounting plates and is connected to a drive 11 by a connecting screw 72. Fig. 5 is connected. The head of the connecting screw 72 can be grasped and turned through a window.

[0087] Fig. 10a shows the underside of the stator part 12 of Fig. 5 with a housing 120 and covers 128A, 128B, between which two groups of six stator magnets or electromagnets 121A, 121B are arranged. The stator part 12 has a connection device 126A, 126B on each side, which can be connected to power supply lines, control lines or measuring lines. A main switch 125 is provided on the right side, as in Fig. 4b As shown, it can be actuated through the guide rail 2 and by means of which the stator part 12 is activated. On the right side, a control device 122 is provided, which has control buttons 1221 and indicator elements 1222, which are accessible through an access opening 1280 in the cover 128A.

[0088] The number of stator magnets or stator coils 121A, 121B is kept as small as possible, but can be selected as needed. Typically, fewer stator magnets 121A, 121B are used for lighter sliding doors and / or lower accelerations, and more stator magnets 121A, 121B are used for heavier sliding doors and / or higher accelerations. Increasing the number of stator magnets 121A, 121B also increases the effective range or length of the stator section 12.

[0089] The main switch 125 and the control buttons 1221 are arranged in a row at the height of the central axis of the stator part 12 and thus also of the central axis of the guide rail 2 and are therefore accessible to the user via the operating channel 28, as shown. Fig. 4b shows.

[0090] Fig. 10b shows the stator part 12 of Fig. 10a After removing the covers 128A, 128B, a power supply device 124 and the control device 122 are visible. The control device 122 comprises at least one processor and power electronics 129, by means of which the stator magnets or electromagnets 121A, 121B are supplied with current, preferably in three phases with a desired phase angle. Sensors, typically Hall sensors, are provided between the two groups of stator magnets 121A, 121B. These sensors are connected to the control device 122 and can be used to measure the magnetic fields that occur.

[0091] By generating alternating magnetic fields through the stator magnets 121A, 121B, which act on the rotor magnets 1122 of the drive 11, for example according to Fig. 5By applying pressure, it is possible to drive the drive 11 in one direction or the other. In this configuration, two control buttons 1221 are provided, by means of which a control menu, preferably with several menu items, can be accessed. As described in the introduction, breakpoints can be programmed by counting the steps from an end stop to a specific breakpoint, setting the breakpoint by pressing the control buttons 1221, and saving the step count.
