Description

The invention relates to a power-operated sliding door for at least one horizontally movable door leaf. As a drive for the door a linear actuator is proposed, which consists of a stationary stator and interacting with this movable rotor.

Of the DE 36 35 258 C1 For example, a magnetic force system for the smooth transport of loads can be associated with at least one magnet attached to the load, which has a ferromagnetic carrier body. It is essential that the magnets interact with at least one vertical pole wall and are arranged substantially parallel to this wall. The magnets are arranged in pairs in the longitudinal direction, which means that always two magnets are considered as a pair, which are shorted by a ferromagnetic plate on one side. The magnets are arranged in an iron U-rail. Directly connected to such magnets is the door to be supported and moved.

In the levitation principle of DE 36 35 258 C1 is in principle a downwardly open U-beam profile in which from below a system of several mutually arranged permanent magnets protrudes. The vertical distance between the magnetic composite and the carrier rail regulates itself without any electronic control. This means that with increasing loads and the magnetic attraction increases.

The advantage of permanently magnetic suspended doors is obvious, as they can be easily moved, which is also the case in the case of a power failure. As a result, a necessary emergency power supply can be omitted, for example, in automatic doors. The floating or hanging of the door can be done without wheels or rollers, wherein the supporting magnets simultaneously represent the rotor magnets of the linear motor.

The WO 94/13055 A1 shows a linear drive in which a stator is arranged with a winding within a wall, which cooperates with a wing of a door on the upper side magnets are arranged, which are used for the suspension and the driving movement of.

A sliding door with a magnetic drive system for a door reveals the DE 10 2004 050 326 B4 , For this purpose, there are at least one magnet row formed in the drive direction with gaps between the individual magnets which have an alternating polarity and a coil arrangement. The coils also have a certain distance from each other. Such a drive system with a magnet array and the associated individual coils has very large cogging torques that arise through the gaps between the magnets and the gaps of the coils. Furthermore, the efficiency of such constructed drive systems is greatly reduced.

In the US 2008/0224557 An electric motor with a Halbach array is described. In this arrangement, the permanent magnets and cooperating coils are arranged to consist of individual segments that produce a preselected magnetic field in a particular direction. By this alignment of the magnets and the coils cooperating therewith, a particular efficiency with respect to the above-described motor of the magnetic flux is achieved.

Thus, the Halbach principle is a special arrangement of permanent magnets, in which the magnetic field almost picks up on one side and on the other side but reinforced acts. This is achieved by the fact that the individual permanent magnets have a different magnetization direction. As a result of this different direction of magnetization, magnetic flux amplification occurs on one side and flux relaxation of the magnetic flux on the other side.

The object of the invention is to provide a power-operated sliding door or the like, which works in addition to a very small size for the drive maintenance-free, has a high efficiency and is inexpensive to produce and has no cogging or Polfühligkeit in a movement of the doors in the de-energized state , Furthermore, the power-operated sliding door should be applicable in a variety of installation situations.

The object of the invention is achieved by the features of claim 1. The dependent claims provide a further embodiment of the inventive concept again.

In order to provide a power-operated sliding door according to the object, which is characterized as having a high efficiency linear drive as a horizontally movable door, it is necessary that the sliding door is preferably moved within a track profile by means of at least one, preferably two roller carriage. Important in such an embodiment is that such a track profile can be used in a variety of applications.

The bifilar winding preferably consists of a multiple number of individual coils, which are used as air coils, ie without grooved iron, are formed. The control of the individual segments of the overall winding is done by a controller / regulation, which may be part of the stator. Such a bifilar winding is preferably wound with a scalar field splitting so that always two wires of the winding run parallel, so as to achieve a scalar vector tilting, which is characterized in particular by the fact that in certain areas there is an increase or weakening of the electrical Feldes within the bifilar winding comes. This scalar field splitting of the individual bifilar windings means that in a clever arrangement of the windings, the individual wires of which preferably consist of a strand, that it turns by the magnetic flux of the windings to a directional, stronger magnetic field for a runner to be described interacts with the stator comes. It is understood that such a stationary stator can extend over the entire length or over partial sections of the route to be traveled. The route can not only be a straight line but this can also be executed in the form of a curve. Such a winding is new in linear drives.

An elongated movable rotor interacting with the stationary stator consists of permanent magnets composed of a multiple pole length of alternating polarity (north / south) with no gaps in between. A pole length consists of several magnetized and arranged according to a specific scheme permanent magnets. The permanent magnets are arranged so that they have a directional, amplified, magnetic flux within a pole length at a pole face directed towards the winding. This contributes to an increase in the efficiency of the linear drive.

To achieve such an amplified magnetic directed flux, the pole length is sized to be a length of two equally long magnets plus a shorter magnet. Preferably, the length of the shorter magnet is dimensioned as half the length of the aforementioned equal length magnets.

In order to intensify the targeted direction of the magnetic flux even more, is directed to the pole face of the two magnets of equal length, another magnet, but only a small, preferably substantially the quarter height of the aforementioned magnets, pole height has. Thus, there is a pole length of preferably four magnets whose magnetization directions have been chosen so that on the flat magnet and thus on its pole face an enhanced directional magnetic flux is present. Each pole length has a different alternating polarity, i. H. At each successive pole length, the North Pole and the South Pole alternate, the individual pole poles directly joining each other without gaps and intermediate poles of iron or the like.

On the opposite side (back to the pole face) of the individual magnets is a ferromagnetic shield, which must have only a small thickness, since in this area no large magnetic flux is present, because at this point a magnetic flux attenuation by the selected magnetic directions of Pole of each magnet is present.

In a preferred embodiment, the individual magnets of a pole length may consist of different magnetic materials, whereby the magnetic flux can be enhanced.

Such a runner consists, according to the length of the door to be moved, of several directly juxtaposed pole faces. These pole faces are modular and can be ranked according to the pole face by a multiple. So it is possible to produce different width doors in modular design in a simple manner. Also, a retrofitting of a manual door by such a rotor according to the invention is conceivable.

In a preferred embodiment, a track profile, which can be used both for holding a displaceable horizontal door leaf or equally also for a pivotable rotary wing, proposed. By such multiple use of such a support profile module enormous costs in terms of development and storage can be saved because for different types of doors always the same support profile module is used.

Such a support profile module according to the invention is characterized in particular by the fact that on the outside of an outer curved contour is present. The curvature is preferably arcuate, in particular partially circular arc or after a polygon. This circular arc section is preferably designed at least as a semicircle, wherein in a further preferred embodiment, the circular arc section describes a range substantially over 180 °. The ends of this circular arc section go directly or with certain fillets in end legs, which form an open area between them. This area between the end legs is intended for the exit of a sliding door leaf.

Within the limited by the arc section outer contour at least one mounting channel is included. Preferably, this is a mounting channel in the middle, ie opposite the opening area between the end legs of the profile. Starting from this middle fastening channel, in a further preferred embodiment, additional lateral fastening channels may also be present. These lateral attachment channels are located from the central attachment channel at an angle of 90 ° on each side. The mounting channels are used to attach the track profile (support profile module) to a ceiling, a wall or the like. Such a mounting channel preferably has an undercut, so that by inserting an additional profile or the like in complementary execution a secure attachment is given within the mounting channel. In a preferred embodiment, the attachment channel has a dovetail shape.

Within the rail profile corresponding running surfaces are available for the use of a roller carriage. The track profile may be in one piece or in several pieces, preferably consist of two sub-profiles. In the execution of a multi-part support profile module, the individual sub-profiles are preferably connected to one another via a connector or the like form-fitting manner. The outer lateral end of the support profile module form corresponding closure elements, which may consist of flat elements in the execution of the sliding door, for example.

In order to carry out a cost-effective storage support, it is necessary that the rail profile should be kept for sliding doors or the like for different mounting options. The use of such a track profile depends on the structural conditions, which may be of different nature. For example, it is possible to mount such a track profile below a ceiling or the like, because the room height is low. At the same time, however, the same rail profile can be used where, for example, on a wall, a partition or the like, the rail profile must be attached laterally. This also applies to versions in which there is a partition or a wall of glass elements.

In order to accomplish an installation for all necessary mounting options for horizontal sliding doors in conjunction with one and the same rail profile, only two connection profiles are necessary according to the invention.

This is in a first preferred embodiment, a connection profile, which can be used on the one hand for the production of a wall or a partition or the like. The connecting profile is designed so that it has at its ends opposite incisions in which, for example, plate-shaped elements in the form of glass panes or metal plates or plastic plates or wood panels or the like can be used. This may for example be a fixed side part and a skylight of a glass door system or the like.

In order to connect the connection profile with the universal rail profile, the connection profile has a projection, which is preferably formed dovetail-shaped or the like. In the middle of the projection is a connecting channel, which serves for non-positive and positive connection with the track profile. The connection profile of the first preferred embodiment is inserted laterally within a mounting channel, which can be present in multiple numbers on the support profile module, and with accurate placement of the rail profile it is screwed via a corresponding connecting element with the connection profile.

In the region of the projection, a contact surface is present on the connection profile, which has a complementary shape to the rail profile. The track profile has in a preferred embodiment in the area where it is connected to the connection profile, a circular arc shape or a curvature. This arcuate course is complementary in the connection profile of the preferred type.

It should be noted that this arcuate course can have a curvature that corresponds to an arcuate shape, in particular a circular arc shape and / or the arc curve approximately as a polygon-shaped outer contour. This can be both a convex and a concave curved surface.

In a further preferred embodiment, of course, the outer contour of the track profile may be designed so that in the region of the connecting channel a straight or sloping surface is present, so that a corresponding complementary surface is used on the connecting profile.

In a second preferred embodiment there is a further connection profile which preferably serves to fix the same rail profile to a building ceiling or the like. As with this type of attachment no further integration of a wall or the like is necessary, this connection profile is made smaller. Also, this connection profile has in its central region on a projection which is also designed about dovetailed. This projection is connected for attachment to the ceiling or the like with a mounting channel within the track profile.

In order to use the rail profile universally, mounting channels are preferably included in multiple numbers in its outer contour. In a preferred embodiment, three mounting channels are included, which are all located, for example, in the circular arc-shaped portion of the outer contour. From the middle mounting channel, which is located in the middle of the rail profile, the two lateral mounting channels are each offset by 90 °. By this offset by 90 °, it is possible that such a track profile can be set both at a lateral attachment point and at an upper attachment point. The mounting channels, which are not needed in a fixture or the like, can be closed by removable covers.

To change the location of the door this is preferably equipped with at least two or more roller carriage.

It is proposed a roller carriage, which consists essentially of a base body having a receiving space. In the receiving space, which is open on one side, a holder can be used with an inserted plate-shaped element, so that by means of the holder in the installed state, the wing is infinitely height adjustable. For mobility of the roller carriage corresponding rollers are arranged on the base body, which are preferably placed above the adjustment of the holder.

The roller carriage can have a wide variety of configurations, wherein in particular in a first preferred embodiment, only rollers for carrying the door are present and in a second preferred embodiment additionally also support rollers can be there to ensure a defined distance between the stationary stator and the movable rotor. In addition to the support rollers and sliders or the like can be used, which maintain a defined distance between the stator and rotor and thus a precise air gap between the winding and the permanent magnet of the linear drive.

The main body has a base or base plate, depart from the side of two sidewalls distanced. In these side cheeks already mentioned support rollers or support rollers are rotatably mounted. Depending on the load, this can be one or more rollers on each side. In continuation of the side cheeks have at their two ends towards each setting spaces in which the holder engages adjustable. The holder consists essentially of a U-shaped component, are formed on the laterally outwardly directed driver. The drivers engage in the Einstellräume and are guided and held there. The guide of the driver and thus the entire holder is done by appropriate dowel pins, which are located on each side in the Einstellräumen. Preferably, two dowel pins are present in each of the setting spaces, so as to prevent tilting of the holder. The U-shaped part of the holder engages between the side walls of the body. The holder extends over the entire width of the plate-shaped element, which may consist of glass or plastic or metal or wood or the like. Attached is such a plate-shaped element within the holder either by an adhesive bond or by positive engagement or by adhesion. However, the preferred embodiment is a gluing, because no holes must be introduced within the plate-shaped element in such a fastening. This would only increase the cost of such a door version with corresponding roller carriage modules and rail profiles.

As the above description shows, the bracket for the roller carriage is also present on the holder. For heavy door leaf designs, multiple rolls can be used. For a door leaf preferably two roller carriages are used, which are preferably mounted in the end regions of the door leaf.

The holder can be designed accordingly in its interior between its side walls so that here a wide variety of materials as well as different thicknesses of materials can be used.

In order to adjust the bracket within the roller carriage, located in at least one of the Einstellräume an adjusting screw for stepless height adjustment of the door leaf. However, it can also be present on each side of the Einstellräume each a set screw. By such a configuration, it is possible to adjust the plate-shaped element in the vertical orientation in its plane. The screws engage in the driver, which are formed on the holder and can thus be adjusted in the installed state of a roller carriage within a track profile or the like.

Due to the fact that the roller carriages are preferably located at the ends of the wide door leaves, it is possible to place a runner between the roller layers over the entire width of the door leaf. Preferably, this runner can be manufactured as a replaceable module and preferably have a support of light metal, to be placed on the roller holders or between the roller carriage, so that the adjustability of the plate-shaped element is maintained.

Even with a de-energized state of the winding is a safe carrying or holding the door in the position given because the arranged behind the winding flat formed without grooves ferromagnetic material with the permanent magnets, because the winding formed with their individual part windings very flat as an air coil is and is thus arranged at no great distance from the permanent magnets. A flat, bobbin-free winding is therefore also possible in particular because the winding is designed as a bifilar winding. The existing behind the winding magnetic inference of its dimensions is dimensioned so that a carrying the door leaf is given.

In a further preferred embodiment, it is possible that the linear drive is equipped with corresponding sensors, in particular for position determination. In addition, in a further preferred embodiment, the control and regulating electronics can also be located within the linear drive at the same time. Preferably, the control electronics is part of the stator. By means of such an embodiment, it is possible for each partial winding to be assigned a separate electronic control unit, wherein the individual partial electronic control units are managed by a superordinate logic. In such an overall administration appropriate programs for the use of the linear drive can be deposited. By a preferred arrangement for the power electronics, for example by a double or triple H-bridge, on the one hand, the power losses are kept very low, moreover, it is possible to achieve effective control of the individual sections of the bifilar winding. Such control and regulating electronics operate at a high clock frequency.

The invention will be explained in more detail with reference to embodiments schematically illustrated in the drawings.

The use of a track profile 10 connected to a connection profile 32 is attached, the shows 1 , Here is the connection profile 32 which has an incision at its upper end 27 and at its lower end an incision 33 has, preferably part of a wall or the like. Inside the cuts 27 and 33 are corresponding wall elements 25 and 26 used.

The track profile 10 is in this possible embodiment of the 1 designed so that it has an outer contour 19 having a curvature or a semicircular portion. It is understood that the outer contour may have any other shape. At the top of the outer contour 19 is a mounting channel 18 available. From the mounting channel 18 are in each case at an angle of 90 ° further lateral mounting channels 21 available. The fastening channels 18 and 21 are the same shape, so the track profile 10 can be attached in a variety of ways.

Within a connection profile 32 is a contact surface 28 present, the one corresponding complementary shape to the outer contour 19 having. Thus, over a large area a plant on positive locking of the rail profile 10 at the connection profile 32 reached. For a secure frictional and positive connection between the connection profile 32 and the track profile 10 ensure is inside the outer surface 28 a lead 31 molded, which also has a complementary shape to the mounting channel 21 having. Preferably, the shape of the projection 31 dovetailed. By means of a connecting channel 29 the inside of the tab 31 is molded, via a connecting element from the inside of the rail profile 10 a screw connection with the connection profile 32 executed in multiple numbers.

Inside the track profile 10 is a roller carriage 36 to see in a cross-sectional view. The roller carriage 36 has support rollers in this embodiment 39 on and support rollers 37 on. The carrying roles 39 lie on corresponding treads 9 of the track profile 10 on. So that the air gap 15 between a runner 3 and a stationary stator 2 is consistent over the entire route, is by the Stürzrollen 37 , which are attached to support surfaces 47 of the track profile 10 supported, taken care of. The runner 3 z. B. is on the carriage 36 or attached to the top edge of the door leaf. In contrast, the stationary stator 2 within the track profile 10 attached. The stator 2 consists essentially of a return plate 8th that with a winding 7 interacts.

The runner 3 consists essentially of permanent magnets 11 . 12 . 13 . 14 . 15 at the air gap 15 facing away from a shield 6 exhibit. Within a recording are the permanent magnets 11 . 12 . 13 . 14 . 15 permanently embedded and z. B. on the roller carriage 36 attached. Furthermore, about the roller carriage 36 indirectly a glass pane 4 of the door, not shown, has been attached. It is understood that the door can also be made of materials other than glass.

When considering the 2 it becomes clear that the stationary winding 7 , which is preferably designed as a bifilar winding with multiple sections, has been stretched long and flat wound, so that a scalar field splitting is achieved by corresponding parallelism of the individual winding wires. By dividing the total winding 7 in several sections or sections a multi-phase operation is possible. Furthermore, the individual sections or sections can be selectively controlled by a suitable control and regulating electronics. To get an effective yield of the winding 7 To achieve this is made of a multi-strand twisted strand. Although this increases the total resistance of the winding but also simultaneously reduces the unwanted eddy currents. The winding of the stator is driven by the control and regulating electronics with an increased frequency, resulting in the design of the control and regulating electronics that cheaper transistors can be used. The winding 7 is preferably made of copper wires, but can be replaced by aluminum wires, if the weight of the stator should play a role.

The permanent magnets 11 . 12 . 13 . 14 of the runner 3 have been grouped into so-called pole lengths P _L , which are still in the 3 will be received. However, it already shows from the 2 that the permanent magnets 11 . 12 . 13 . 14 have within a pole length P _L certain arrangement, the arrows used there within the magnets 11 . 12 . 13 . 14 of the 2 to reproduce the magnetic flux and thus also a certain polarity (North Pole or South Pole). By a targeted magnetic field adjustment a directed field correction is made by means of certain magnetic magnetization directions. In such a field correction, the magnetic material is in addition to a certain magnetic directional orientation even more so geometrically composed that, for example, to the air gap 15 towards a magnetic flux enhancement and, for example, to the shielding plate 6 it comes to a flux mitigation comes.

From the 3 can the arrangement of the permanent magnets 11 . 12 . 13 . 14 a first preferred embodiment. Such an arrangement of juxtaposed permanent magnets 11 . 12 and 14 is referred to as pole length P _L. This is shown by the permanent magnets 11 and 12 each have a length L ₁ and L ₂ . L ₁ is essentially equal to L _{2 in} terms of its dimensions. The permanent magnet 14 , next to the permanent magnet 12 in the embodiment of 3 is placed has a length L ₃ . The length L ₃ measures substantially half the length of L ₁ or L ₂ . Thus, the following statement results for the pole length P _L : P _L = L ₃ + L ₂ + L ₁ where L ₁ = L ₂
and L ₃ = ½L ₂
is.

P _H sets the pole height. The pole height P _H is approximately ½P _L in the preferred embodiment. P _H = ½P _L

Again 3 it can also be seen is another permanent magnet 13 present, over the lengths L ₁ + L _{2 of} the permanent magnets 11 and 12 extends. This permanent magnet 13 has a height H ₁ which measures approximately ¼ of the pole height P _H. H ₁ = ¼P _H

The height of the permanent magnets 11 and 12 plus the height H ₁ gives the P _H. The magnet 14 extends over the entire pole height P _H.

Thus, it turns out that a pole length P _L with a directed magnetic flux at the pole face 16 from the permanent magnets 11 . 12 . 13 and 14 in a first preferred embodiment of the 3 can exist. In order to achieve the directional magnetic flux, have the permanent magnets 11 . 12 . 13 . 14 a certain magnetization direction. This is indicated by the arrows within the 3 the individual permanent magnets 11 . 12 . 13 . 14 been presented. For example, the arrowhead with the south pole and the arrow end with the north pole has been designated. By such vector displacement of the magnetization in the individual strands of the targeted magnetic flux and thus a correction to a normal magnetization of the pole face 16 reached outgoing magnetic flux. There is almost an addition or targeted amplification or alignment of the individual magnetic fluxes. For example, the permanent magnet 14 has been magnetized in the direction of the pole length P _L. This magnetic flux is added to the approximately 45 ° extending magnetization directions of the permanent magnets 11 and 12 , By using the permanent magnet 13 is next to the magnetic field alignment of the magnets 11 . 12 . 13 . 14 at the same time an assembly aid in the assembly of the pole length P _L achieved.

The permanent magnets 11 . 12 . 13 . 14 can consist of a wide variety of permanent magnetic materials. The preferred material is the rare earth type with cobalt alloys, ceramic ferrite alloys and rare earth iron alloys besides neodymium-iron-boron alloys. So it turns out that the individual permanent magnets 11 . 12 . 13 . 14 not all of the same magnetic material, so in addition to a cost reduction and a better targeted magnetic flux at the pole face 16 to effect.

In a second preferred embodiment of the 4 is another embodiment of an arrangement of permanent magnets 11 . 12 . 13 . 14 . 17 represented, in which the individual pole lengths P _L according to the 3 overlapping by another magnet 17 achieved, for example, on the magnets 11 and 12 but extends across the next pole length P _L. By such an arrangement of the permanent magnet 17 becomes a further orientation of the magnetic flux towards the pole face 16 causes.

In addition to the user-friendliness, the design of such a linear drive for the simple design of a sliding door in single-leaf design is also suitable. With a corresponding control, only a door leaf can be opened even with a double-leaf sliding door. It is understood that such an intelligent control, within the linear actuator 1 can be integrated, in addition to a continuous speed control and a current limit and thus has a force limit.

The modularity of the linear drive according to the invention results, in particular, from the pole lengths P _L present in the grid dimension, which can each be strung together many times. Furthermore, by the flat ironless Luftwicklung, which preferably consist of single windings or sections for different phases or the like and have no carriers or bobbins.

Such a pre-described linear drive is not only inexpensive to produce for all door leaf widths, but he also has low geometric dimensions, which are below those that are known from linear actuators of the prior art.

Furthermore, the 5 a damping device 41 are removed, preferably within a channel 24 of the track profile 10 is used. Such a damping device 41 would when moving the plate-shaped element 4 in the end positions a gentle shrinkage of this plate-shaped element 4 cause. To such a cooperation between the damping device 41 and the plate-shaped element 4 to be able to effect, is on the roller carriage module a projection 42 present, for example, with a release lever 43 the damping device 41 interacts.

The preferred embodiment of 5 shows an attachment of the rail profile 10 on a blanket 34 or similar. With this type of attachment becomes a connection profile 35 used, in this embodiment, the upper mounting channel 18 with the lead 31 in operative connection. About appropriate fasteners 40 , becomes a fixture on the ceiling 34 executed.

On the left side of the 5 is in this embodiment also the connection profile 32 been used, which here leads to the connection profile 32 with limiting legs also on the ceiling 34 or the like is present. In the nick 27 In this case, no plate-shaped element has been inserted, whereas, however, in the incision 33 the plate-shaped element 26 is placed. This embodiment may, for example, as a fixed side part 26 without skylight with a horizontally movable door leaf 4 be executed. Attached is the connection profile 32 in the form already described about the projection 31 inside the mounting channel 21 with the track profile 10 ,

The 6 shows the execution of a sliding door with a wing 4 in which the track profile 10 on a wall 44 via the connection profile 35 is fixed. The connection between the connection profile 35 and the track profile 10 will also be over the lead 31 in connection with the mounting channel 21 and appropriate screwing carried out.

A preferred embodiment of the roller carriage 36 give the 7 again. There is the roller carriage 36 essentially from a basic body. The base for the base body forms a base plate or base plate 48 from the side sidewalls 50 distanced by the base plate 48 depart. At the end of the side cheeks 50 There are parking spaces on each side 32 present, essentially by one of the side cheeks 50 outgoing bend 51 with adjoining spacer legs 53 and adjoining angled base legs 55 form. By this offset of the bend 51 and the return over the base leg 55 becomes the setting room 32 educated. It is understood that on each of the side cheeks 27 a setting room 32 can be present.

Within the setting room 32 are on the one hand dowel pins 45 , preferably in duplicate in each setting room 32 available. Between the dowel pins 45 is located at least in one of the setting rooms 32 a set screw 46 ,

By at the ends of the side cheeks 50 existing bulges for the Einstellräume 32 from the side cheeks 50 Show away, forms above the Einstellräume 32 Space for carrying roles 39 and the support rollers 37 ,

On the base plate 40 is the lead 42 for a limit switch or end position damping 41 ,

In the 7 is a possible embodiment of a roller carriage 36 reproduced in a side view, here, within a distanced by side cheeks 50 Essentially educated recording room 59 , a holder 5 is used. The holder 5 holds over spacers or bonds 56 the plate-shaped element 4 ,

The holder 5 consists essentially of a soil 48 , starting from the side cheeks 49 are present at which driver 54 are formed. The drivers 54 stand by the side cheeks 49 and protrude into the lateral Einstellräume 32 into it. Here are the drivers 54 designed so that in them corresponding holes for the dowel pins 45 can intervene. Through the dowel pins 45 becomes a more accurate straight seat of the bracket 5 reached. On the other hand, it is also true that over the dowel pins 45 virtually the entire roller carriage 36 with the bracket 5 and thus with the plate-shaped element therein 44 is connected.

It is also located in the carriers 54 a corresponding thread for receiving the screws 46 on at least one side of the Einstellräume 32 is available.

A use of two roller carriages 36 in connection with the plate-shaped element 44 show the 8th , This embodiment may, for example, be a horizontally displaceable wing of a door. The roller carriages 36 are positively and positively with the holder 5 connected. In the holder 5 is previously the plate-shaped element 44 been used. In this type of execution of 8th Such a prefabricated component can be supplied for further use. This can, for example, insertion into a track profile 10 be to create a horizontally movable door. Due to the high prefabrication can therefore be such plate-shaped elements 44 with roller carriage modules 36 just equip. Between the roller carriages 36 is by attachment to this example, the runner 3 positive and positive fit with the plate-shaped element 4 connected. Through this representation it is also clear that a replacement of the rotor 3 can be realized very quickly in case of a defect.
