Description

The invention relates to a sliding door system with at least one sliding door leaf, preferably an automatic sliding door system with a drive motor, with a profile housing, at least one roller carriage guided in the profile housing and a suspension device for the sliding door leaf connected to the roller carriage, wherein the suspension device is preferably designed as a suspension and adjustment device.

Known door systems, e.g. automatic sliding door systems, are made up of several components, such as an electric motor, electronic control unit, carrier with drive, locking device, etc. The individual components are usually arranged next to one another on a stationary horizontal carrier. The arrangement is essentially in a common vertical plane in the area of the carrier. This results in a relatively large construction height. Furthermore, the assembly effort is usually relatively high, since the individual components are each arranged individually on the carrier. They are usually attached separately to the carrier using their own fastening devices.

The drive usually consists of one or more sliding panels guided by roller carriages in a stationary guide rail. The sliding panels are attached to the roller carriages by means of support screws. There are usually two roller carriages for each sliding panel. The structure of such conventional roller carriages is described in DE-OS 36 02 440 or DE-GM 91 13 903, for example. The disadvantage of this is the size of the drive, which is determined by the roller carriage and the suspension of the sliding panel. On the one hand, the roller carriage must be guided safely, and on the other hand, there must also be enough space for adjusting the sliding panels.

Another very compact drive available on the market has a roller carriage with two horizontal axes and a total of four rollers, which is guided in a U-shaped profile housing. The external visual impression of this drive is, however, disadvantageous, as the suspension and adjustment device is clearly visible outside the profile housing.

The object of the invention is to develop a sliding door system with a small installation size.

The problem is solved with the subject matter of claims 1, 30 and 38. By using a profile housing which has a web on at least one vertical leg, preferably on both, the profile is divided into an upper area and a lower area and the sliding door leaf engages in the lower area. The roller carriage is guided in the upper area, with the web being designed as a guide device for this purpose. The suspension and/or adjustment device is preferably arranged in the lower area and connected to the roller carriage by a threaded screw. The leaf is suspended on the threaded screw via a bracket, with the transverse positioning taking place via lateral receiving slots either on the threaded screw or on the leaf-side fastening. In this way, a drive with a very compact construction and visually appealing design is achieved.

Further features of this embodiment are listed in the subclaims.

In another embodiment, the rollers have a vertical axis of rotation. The axes, which are housed in a vertical pressure bearing, support the sliding sash via a conventionally constructed suspension device with height adjustment.

Another example shows a roller carriage with a U-profile body that opens downwards. The rollers are mounted with their axes in the outer sides of the vertical legs. The wing that engages in the U-profile is supported by cross bolts that run between the legs, with the bearing of the cross bolts having an eccentric device for height adjustment.

Alternatively, the axes of rotation of the rollers can also be arranged at an angle to the horizontal, preferably offset from one another crosswise. In one embodiment, a vertical roller and a horizontal roller designed as a support roller are connected to an L-shaped roller carriage.

In a modified design, the drives can be equipped with running balls which are housed in a running groove of the rail housing and support a bearing plate. The bearing plate carries a U-shaped receiving body for suspending the wing.

In all versions, the sliding wing engages in the drive housing so that the upper edge of the sliding wing is concealed.

The invention is explained in more detail in the figures.

The following applies both to the embodiment shown in Figure 1 and to the modified embodiment shown in Figure 2 :

The sliding wing 10 is mounted so that it can move via a drive 1. The drive 1 is designed as a drive module. The drive motor and the control device are arranged in a motor and control module 2. A carrier module 3 and a display and/or communication module 4 are also provided. In the embodiment shown, all modules each have a profile housing. The modules extend in the sliding longitudinal direction of the drive, preferably across the entire width of the door. They are arranged parallel to one another in a common horizontal plane in the direction of view perpendicular to the door plane. They each lie against one another with their front sides facing one another. They each have the same height H, e.g. 60 mm or 70 mm. They are arranged with their top and bottom sides aligned so that they form a composite cuboid body of height H.

Regarding the fastening of the modules in the embodiment in Figure 1 , the following applies:
The modules 1, 2, 3, 4 are attached to each other by hanging them. For this purpose, undercut longitudinal grooves 61 are provided in the front sides facing each other.

and complementary, ζ. B. in cross-section hook-shaped projecting longitudinal edges 62 are provided, which engage with one another. Additionally or alternatively, screw connections can be provided in the front sides facing each other.

The following applies to the embodiment shown in Figure 2 as well as to the versions in Figures 13 and 14: To attach the drive module 1, an L-shaped support module 3 is attached to the post or the transom 81 of an existing post-transom construction 8 (see also Figure 8). The support module 3 extends over the entire height of the transom 81 and rests with the short leg 3a on the horizontal upper edge of the transom 81. The lower edge of the transom 81 and the support module 3 are at the same height. The support module 3 is screwed to the transom 81 and a reinforcement profile 81b accommodated inside the transom 81 using fastening screws 1e. To adapt the support module 3 to posts 82 resting above the transom 81 (Figure 8), the short leg 3a has a predetermined breaking point 32 at its base. The corresponding leg area can be notched out by simply sawing. To accommodate the drive module 1, the support module 3 has a hanging device 33 and a clamping device 34. The new fastening technology makes it possible to mount the drive module 1 and all other modules by simply hanging and clamping them on the front sides facing each other. Instead of the attached posts 82, the posts 86 can also be designed as continuous load-bearing posts.

The hanging device 33, which connects the carrier module 3 to the drive module 1, consists of a first dovetail half-profile 33a running horizontally near the upper edge of the vertical leg 3b. This engages in a dovetail counter-profile 13, which is formed at the same height in the profile rail 63 of the drive module 1. After hanging, the upper and lower edges of the carrier module 3 and the drive module 1 are each at the same height.

The clamping device 34 is used to fix the modules 1 and 3 together using the suspension device 33. It consists of several profile pieces.

ken 35, which are arranged in a horizontally running recess 34a, open towards the drive 1, near the lower edge of the vertical leg 3b. Each clamping piece 35 rests with a flat base surface 35a in the recess, leaving room for movement in the vertical direction. The front of the clamping piece 35 is formed by a second dovetail half-profile 35b, the profile of which runs complementarily to the first dovetail half-profile 33a. The opposite side of the clamping piece 35 ends with a wedge surface 35c. The second dovetail half-profile 35b engages in a second dovetail counter-profile 14, which is formed in the profile rail 63 of the drive module 1 at the same height. To enable the engagement, the clamping piece 35 is raised vertically in the recess and then lowered again. For this purpose, recesses 3c are provided on the undersides of the vertical leg 3b. After the engagement, the clamping piece 35 is fixed using a clamping screw 35d, which rests with its free end on a counter surface, e.g. a horizontal bar 35e of the carrier module 3, thus preventing the dovetail connection from coming loose.

A modified embodiment of the carrier module 3 is shown in Figure 22a. The carrier module 3 has a horizontally running dovetail groove 301 near its upper end, into which several short angle pieces 300 with a dovetail profile 302 matching the groove 301 are inserted. Each angle piece 300 carries a horizontal leg 303, which rests on the bar 81 analogously to the horizontal leg 3a in Figure 2 and enables the carrier module 3 to be easily assembled. Because the horizontal leg 303 is not arranged centrally on the angle piece 300, the construction allows easy adaptation to different bar heights by inserting the angle piece 300 rotated by 180 degrees into the dovetail groove 301. The horizontal leg 303 is then in the position shown in dashed lines. Further adaptation options to different transom constructions are possible by using differently shaped angle pieces 300, whereby the same carrier module 3 can still be used. Alternatively, a carrier module 3 with several dovetail profiles is also possible.

len in different vertical positions, whereby the angle piece 300 is inserted at the appropriate height.

On the top of the vertical leg 3b there is a longitudinal groove 310 with a semicircular cross-section. This serves as a cable guide if required, especially when laying cables from one side of the door to the other.

In order to simplify the fastening to the post 84, 86 or the bolt 81, the carrier module 3 shown in Figure 22a has a horizontally running continuous V-groove 320 on the side of the vertical leg 3b facing the drive module 1. This prevents the drill from going astray when drilling fastening holes. Alternatively or in addition to the V-groove 320, fastening holes in the form of elongated holes in a vertical and/or horizontal orientation in a grid arrangement for the fastening screws 1e (not shown) can already be present. These allow the height and transverse adjustment of the carrier module 3 on the bolt 81.

An L-shaped cover 360 is clipped onto the underside of the vertical leg 3a, the horizontal leg 361 of which covers the entire underside of the carrier module 3 and the vertical leg 362 of which encompasses the left-hand vertical leg 63a of the drive module 1. The two lugs 363, which are used to clip into the recess 3c, can be seen in Figure 22b. To adapt to different door widths, the cover 360 has several predetermined breaking points. In addition, the cover 360 has a receiving groove 65 on its underside for a sealing brush 66, which seals the carrier module 3 towards the wing 10 (not shown).

Figure 22b shows the detail XXII in Figure 22a in an enlarged view. In contrast to the description in Figure 2, the clamping device 34 has not only the drive module side, but also the carrier module side a dovetail groove 330, into which the clamping piece 35 engages with a dovetail profile 35b. This has the advantage that the clamping pieces 35 can be attached to the corresponding holes before assembly without the risk of falling out.

the position in the carrier module 3. This has no influence on the functionality of the fastening technology already described.

Another detailed solution is the dirt trapping grooves 340 that run lengthwise at the deepest point in the right dovetail profile 330. Any dirt can collect there without affecting the accuracy of the counterpart 35b in the dovetail profile 330. Instead of installing a dirt trapping groove 340 in the dovetail profile 330, the outer tip of the counterpart 35b can also be shortened to create a dirt trapping area 341, as shown as an example on the left side. Such dirt trapping devices 340, 341 can also be found on the upper suspension and clamping device 33 with dovetail profile 33a.

The motor and control module 2 is also attached to the drive module 1 by simply hanging it and clamping it on the front sides facing each other. For hanging, the drive module 1 has an undercut longitudinal groove 61 on its upper horizontal edge, into which the motor and control module 2 is hooked with a complementary longitudinal edge 62 that projects in a hook-like cross section. The clamping is carried out using a clamping device 34, which is identical to the device in the carrier module 3, but is arranged at an angle of approximately 30° to the horizontal. A horizontally running groove 15 in the middle of the vertical leg 63b serves to accommodate the wedge surface 35c on the clamping piece 34. The clamping piece 35 with the dovetail half profile 35b engages in a dovetail counter profile 27c, which is also inclined against the horizontal, on the vertical leg 27a of the motor and control module 2. The clamping device 34 is clamped in this position by a clamping screw 35d and the two modules 1, 2 are fixed to one another.

The drive can be attached to the vertical wall of the housing, e.g. by screw connection as shown in Figure 1 in the area of the vertical housing leg of the drive module 1. Alternatively, the carrier module 3

be installed in front of the drive module 1 and be attached to the vertical housing leg of the support module 3. Instead of being attached to a vertical wall, however, it can also be attached to the upper horizontal ceiling or to the lintel, preferably by means of a screw connection in the area of the horizontal cover wall of the guide rail module 1 or the support module 3.

For fastening to the wall, ceiling or lintel, separate fastening brackets can also be provided, which are fastened on the one hand to module 1 or 3 and on the other hand to the wall or ceiling. Such fastening elements can also be inserted into the housing of modules 1 or 3 or connected to the reinforcement profile or flat material incorporated in the module housing.

To illustrate the fastening options, Figure 8 shows a post-and-beam construction 8. The vertical posts 84 are attached to the ceiling and connected to one another via a horizontal beam 81. The support module 3 and/or the drive module 1 are attached to this beam 81. The two door leaves 10 are shown in the closed position. For this design, four variants are provided for supporting the beam 81 or the support module 3, which are described below:

In the first variant, the boundaries of the fixed field wings 12, e.g. vertical profiles, are designed as load-bearing boundary posts 86, which support the bar 81 in the interior area in addition to the side posts 84. Variant 2 provides for the bar 81 to be attached hanging from the floor ceiling 83 by posts 82. In variant 3, the bar 81 is suspended from the floor ceiling 83 using steel cables or rods 85a, 85b. These elements can be cut to length on site and adjusted in height. The cables or rods 85a, 85b can be arranged both freely visible 85b and invisibly 85a within the posts 82. The fourth variant provides for the fixed field wing itself to be designed as a supporting element and is described in Figures 10 and 11.

Figure 10 shows a variant in which the fixed panel wing 12, which can be designed as an all-glass, insulating glass or thermally insulated wing, is used to support

of the carrier module 3 and the latch 81. The fixed field sash 12 has a clamping device 12a on its upper horizontal edge and is initially positioned under the latch 81, whereby a gap initially remains between the clamping device 12a and the latch 81. For secure assembly, it is necessary that the carrier module 3 and the latch 81 are at the same height with their lower edges, or a device is required that bridges any existing height difference. The clamping device 12a consists of several hexagon screws 12b received in an anchor 12g in the upper edge of the sash. The hexagon screws 12b each have a pin 12c, which serves to receive a clamping strip 12d running parallel to the upper edge of the sash. The hexagon screws 12b are then loosened one after the other from their anchorage 12g until the clamping strip 12d rests against the support module 3 or the latch 81, thereby clamping the fixed panel sash 12 to the latch 81. Finally, cover panels 12e are attached to the clamping strip 12d via locking elements 12f in order to visually cover the gap between the upper edge of the sash and the clamping strip 12d.

Figure 11 shows a modified embodiment in which the fixed field wing 12 is only braced against the carrier module 3 without resting on the latch 81. A support is also possible in which the fixed field wing 12 is only braced against the latch without resting on the carrier module.

In Figure 9, the fastening options for the drive module 1 or the carrier module 3 to the bar 81 or another horizontal beam are shown again in summary. Figure 9a shows a direct screw connection 1e of the drive module 1 to the bar 81, as is also indicated in Figure 1. To increase the rigidity, a dark reinforcement profile 81b is accommodated in the bar 81. In Figure 9b, a rail 1f is arranged on the drive module 1 over the entire length of the latter, which rests on the bar 81 during assembly and is screwed to it. The embodiment in Figure 9c corresponds to that in Figure 2, in which an L-shaped carrier profile 3 is screwed to the bar 81 and the drive module 1 is suspended via the suspension rails.

Device 33 with dovetail profile 13 is suspended in the carrier module 3 and clamped with the clamping device 34.

In an alternative embodiment shown in Figure 9d, the drive module 1 takes on a stiffening or support function instead of the support profile 3. For this purpose, the drive module 1 is designed with two hollow chambers for the introduction of the dark flat material 81c in an L shape. These are preferably steel rails, which increase the rigidity of the drive module 1 in the self-supporting assembly required in the majority of applications. The hollow chambers with the flat material 81c are located in the two vertical legs and the middle part of the U-shaped drive module; in other embodiments, U-shaped reinforcing materials can also be introduced. These can either consist of one part or be composed of two or more parts. The advantage of this embodiment is that no additional profile has to be used to achieve a higher load-bearing capacity.

Several embodiments of the drive module 1 are described below. The following applies to the design of the drive shown in Figure 1 :
The drive module 1 has a sliding guide, which in the embodiment shown includes rollers 1a with a vertical axis of rotation. The rollers 1a run on stationary running surfaces 1b, which lie opposite one another in a common horizontal plane. They are formed on the opposite legs of the profile housing 1c of the drive module. The running surfaces 1b are convexly curved, but can also be concave or designed as inclined flat surfaces.

Preferably, several rollers are arranged one behind the other in the running direction, which roll on opposite running surfaces, i.e. that some rollers roll on one running surface, the other rollers on the other running surface.

The rollers 1a have a vertical thrust bearing 1d. The axles housed in these bearings support the sliding sash 10. For this purpose, a suspension device with height adjustment is provided, which can be constructed in the conventional manner with a screw and nut.

Instead of the running gear shown in Figure 1 with the rollers with a vertical axis, rollers with a horizontal axis can also be used, e.g. conventionally constructed roller carriages. The construction of such roller carriages is described, for example, in DE-OS 36 02 440. Roller carriages can also be used which - as shown in Figure 3 - have a U-profile body 21 open downwards towards the wing 10. The rollers (not shown) are arranged on the sides of the U-legs 22, 23 facing away from one another, with the bearing axes of the rollers being clamped into undercut longitudinal grooves 22a, 23a on the outside of the U-legs. Cross bolts 24 are provided for suspending the wings 10, which are arranged in opposite bearings in the U-legs. The bearings have an eccentric device so that the height of the wing 10 suspended on the cross bolt can be adjusted by rotating the cross bolt.

Instead of rollers with vertical or horizontal axes, rollers with axes of rotation arranged at an angle to the horizontal can also be used, preferably with rollers offset crosswise from one another and arranged one behind the other in the running direction. The different arrangement of the rollers makes it possible to design drive modules 1 with different cross-sectional dimensions.

Alternatively, drives with running balls can also be installed. In the ball drive shown in Figure 4a, the balls 36 run in a running groove 37 in the drive housing 1c and support a bearing plate 38 with corresponding running grooves 39. A suspension device for the sliding wing 10 with a U-shaped receiving body 31, which is constructed similarly to the body 21 in Figure 3, is suspended in the bearing plate 38. The bearing plate 38 can form the body of a carriage which has 3 running balls on each of the running sides. As with the drives described above, the sliding wing engages in the drive housing so that the upper edge of the sliding wing is concealed.

Another embodiment of a drive 1 with a vertically and a horizontally arranged roller 69v or 69h is shown in Figure 4b. The drive 1 with its essentially L-shaped housing 63 is attached to a post 84 via an intermediate support element 3. The housing 63 has a vertical leg 63a resting on the support element 3, an elongated horizontal leg 63d at the top, and a short second vertical leg 63b arranged approximately in the middle of the horizontal leg 63d.

A horizontal web 64a with a running surface is attached to the first vertical leg 63a in the lower third, on which the vertically standing roller 69v, i.e. with a horizontal axis of rotation 68, is guided. The axis 68 of this roller 69v is mounted in the vertical leg 6v of an L-shaped roller carriage 6. Above the roller carriage 6 and the vertical roller 69v, a second roller 69h is arranged horizontally, i.e. with a vertical axis of rotation. The axis 68 of this roller 69h is mounted in the horizontal leg 6h of the roller carriage 6. The roller 69h is guided with play between the two vertical legs 63a and 63b of the profile housing 63 immediately below the upper leg 63d. Each of the two vertical legs 63a and 63b has a running surface, whereby the roller 69h is supported on only one of the two running surfaces. This second roller 69h acts as a support roller and prevents the roller carriage 6 with the wing 10 attached to it from tipping over.

The roller carriage 6 in the form of an upside-down "L" now forms an additional receiving space below its vertical leg 6v for the height adjustment of the wing 10. The wing is connected to the horizontal leg 6h of the roller carriage 6 via a conventionally designed suspension and adjustment device 7. Alternatively, the wing 10 can also be attached to the vertical leg 6v of the roller carriage 6 via a suspension and adjustment device. The wing 10 is arranged flush under the horizontal leg 6h of the roller carriage 6 and can be adjusted depending on the setting and design of the

The upper edge of the suspension and adjustment device 7 can engage more or less far between the two L-shaped legs 6h and 6v of the roller carriage 6.

Near the outer end of the horizontal leg 63d of the profile housing 63, there is a receiving groove 350 on the underside for attaching drive and control elements. The front of the profile housing 63 is closed by an L-shaped cover 5, which is hooked onto an upper longitudinal edge 62 on the upper horizontal front edge of the profile housing 63. The lower horizontal leg of the cover 5 extends directly to the sliding wing 10 and is at the same height as the support element 3 and the left vertical leg 63a of the profile housing 63. As with the drives described above, the sliding wing 10 also engages in the drive housing 63, so that the upper edge of the sliding wing is concealed. However, the special design of the roller carriage 6 and the arrangement of the rollers 69v, 69h result in additional scope for adjusting the height of the sash 10.

Another embodiment of a drive with horizontal axes is shown in Figure 6. The drive module 1 corresponds in structure to that in Figure 2 and consists of a U-profile 63 with an almost square cross-section. A horizontal central web 64a and 64b is provided on the two vertical legs 63a and 63b, which divides the profile into an upper area 6a and a lower area 7a. An opening remains in the middle for the passage of the suspension and adjustment device 7 for the sliding sash 10 (not shown). The central webs 64a, 64b are designed as running surfaces 1b, 1b' for the roller carriage 6, with one central web 64b having a running surface 1b' with a curved cross-section and the other central web 64a having a running surface 1b with a flattened cross-section. The webs 64a, 64b have receiving grooves 65 facing one another with sealing brushes 66 arranged throughout. The upper region 6a of the profile rail 63 with the roller carriage 6 contained therein is thereby hermetically sealed and the ingress of dirt or foreign bodies is prevented.

The roller carriage 6 shown in Figures 6 and 7 consists of an elongated base body 67 in which two continuous horizontal axes 68 arranged one behind the other are mounted. Each of the axes 68 carries two external, differently shaped rollers 69. The roller carriage 6 is guided with its rollers 69 in the upper area 6a of the profile rail 63 on the center webs 64a, 64b. According to the design of the running surfaces 1b, 1b', the rollers 69a arranged on the left-hand side relative to the running axis have a flattened running surface 1b and the rollers 69b arranged on the right-hand side have a spherical running surface 1b'. The running surface 1b is flattened to form a horizontal, flat running surface. The roller-side running surface of the roller 69a is designed as a loose bearing on the flattened running surface 1b in the axial direction. The flattening of the running surface 1b in conjunction with the roller shape thus serves to compensate for tolerances. To increase the guide reliability, a curved support profile 63c that complements the profile of the roller 69b is arranged on the top of the chamber 6a, opposite the likewise curved running surface 1b' of the center web 64b. The support profile 63c engages in the profile of the roller 69b, but does not touch the roller 69b. The roller carriage base body 67 is also guided only at a small distance from the profile 63, but without touching it. In this way, the roller carriage 6 is prevented from "lifting off" or even jumping out of the guide.

The rollers 69a with flattened running surface 1b each have a circumferential recess within the running surface 1b. This serves to accommodate an elastic band 2d, which opens the sliding sash in emergency operation. The elastic band 2d is connected to the sliding sash 10 at one end and is supported in a fixed position at the other end, but can also be pre-tensioned and moved along with the sash. It serves as an auxiliary drive for emergency opening of the sliding sash 10 if the motor 2a fails. In modified versions, the elastic band 2d can also be used for emergency closing.

To secure the drive module 1, there is a horizontal groove 13 near the upper edge of the leg 63a, with which the drive module 1 is suspended in the carrier module 3 as already described in Figure 2. A

second horizontal groove 14 near the lower edge of the leg 63a is used for tensioning by the clamping device 35 arranged in the carrier module 3. A further groove 15 in the middle of the opposite leg 63b is used for tensioning the motor and control module 2, which is previously hung in a horizontal groove 61 on the upper edge of the leg 63b.

The embodiment of the drive module 1 shown in Figures 13 and 14 has two additional receiving grooves 600 on the undersides of the center webs 64a and 64b. These are used to attach buffers 610 to the ends of the module 1, onto which the roller carriages 6 run in their respective end positions. The buffer 610 itself is shown in Figure 19. As can be seen in Figure 20, the drive module 1 has a recess 630 in the middle area of the longitudinal extension with shortened center webs 64a, 64b, which allows the roller carriages 6 to be inserted or replaced in the drive module 1. This recess 630 can either also be secured by buffers 610 or closed with a cover.

As can best be seen in Figure 7 , in this embodiment a driver 25 is attached to the underside of the roller carriage 67, which is preferably connected to the drive by a drive belt driven by the drive motor 2a. The driver 25 engages with its upwardly bent bracket end surface 25a in a recess 67a on the underside of the roller carriage 6. In this position it is fixed with two fastening screws 26 leading through from the top of the roller carriage. The bracket end 25 is approximately at the level of the two central webs 64a, 64b.

The suspension and adjustment device 7 shown in the side view in Figure 7a engages vertically with a hexagon screw 71 in a cross bolt 72a mounted in the roller carriage base body 67. The engagement takes place between the rollers 69 when viewed from the front (Fig. 6) and between the axles 68 when viewed from the side (Fig. 7). A bracket 74 connected to the sliding sash 10 is mounted on the screw head 71a and secured with a lock nut 73. The bracket 74 is attached to the two downwardly bent ends with

a base plate 75. This base plate 75 is mounted so that it can move axially in an undercut recess in the upper edge of the sash and is pushed in from the vertical edge of the sash. The bracket 74, shown again in plan view in Figure 7b, has a slot 74a in the middle that runs perpendicular to the plane of the sash for hanging the screw head 10, whereby the screw head 71a rests on the underside of the bracket 74 and a lock nut 73 is tightened on the top of the bracket 74 to fix the bracket on the screw head 71a. After loosening the lock nut 73, it is possible to remove the bracket 74 together with the sliding sash 10 from the suspension 7 by sliding it sideways. This allows the adjustment to be carried out without being hindered by the sash 10 and simplifies assembly.

To assemble the sash, the base plate 75 is first inserted into the sliding sash 10 and fixed in the desired position with clamping screws (not shown). The bracket 74 is then fixed to the base plate 75 using a screw connection 76. Only after the hexagon screw 71 has been set to the desired height is the sash 10 hung into the device 7 via the bracket 74 via the slot 74a and secured with the lock nut 73. This allows for simple and safe adjustment. Maintenance and repair work are also made much easier and faster by the ability to unhook the sash 10 again.

An alternative suspension and adjustment device 7, which has additional scope for adjusting the height of the wing 10, is shown in Figures 7c and 7d. Instead of a receiving slot 74a, the bracket 74 has a receiving hole 74b, via which it is suspended on the head 71a of the hexagon screw 71. Once the bracket 74 has been mounted, it can no longer be detached from the screw 71. Instead, the bracket 74 can be suspended at its ends connected to the wing 10. For this purpose, lateral receiving slots 74c are formed on these two ends of the bracket 74 for introducing the screws 76 engaging in the upper edge of the wing (of which only the one on the right is shown in Figure 7d), which are shaped similarly to the original receiving slot 74a. The two receiving slots

74c also allow the sash 10 to be positioned transversely or unhooked. The height adjustment is carried out in the same way as in Figures 7a and 7b. However, the fact that a lock nut 73 for securing the bracket 74 on the hexagon screw 71 can be dispensed with advantageously results in additional height flexibility.

The following applies to the motor and control module 2 shown in Figure 1:
The motor and control module 2 has a motor 2a and a control unit (not shown). The motor 2a is designed as a relatively narrow, essentially rod-shaped motor. The output pinion 2c is coupled in motion to the wing 10. For this purpose, a transmission device (not shown in detail) is provided between the output pinion 2c and the wing 10. For example, a conventionally constructed drive belt device with revolving drive belts guided over deflection rollers 2b can be provided, with one deflection roller 2b being driven by the motor 2a and one strand of the drive belt being connected to the wing 10 via a driver.

Deviating from the embodiment shown in the figure, the motor output shaft of the motor can also pass through the profile housing walls that separate the motor and control module from the drive module 1. The transmission device, e.g. the drive belt device, can be arranged in the drive module 1. It can itself be designed as a module that can be plugged into the drive module 1.

In the embodiment shown in Figure 1, the motor and control module also contains an elastic band 2d, which is attached at one end to the wing 10 and at the other end to the profile housing of the module 2. The elastic band is tightened when the wing is closed by motor. In the event of a power failure, the elastic band ensures that the door opens automatically. In contrast to the embodiment shown, the elastic band 2d can also be arranged in the drive module 1, preferably supported in a similar way. In Figures 2 and 6, it is provided that the elastic band 2d is installed in a space-saving recess within the running surface of the

r\A * * m u«f «4

Rollers 69a are guided. The motor and control module 2 also has a hollow profile chamber in which the electrical cables 2e are guided.

The following applies to the motor and control module 2 shown in Figure 2 : The motor and control module 2 has a profile housing 27, which in terms of dimensions is the same height as the drive module 1 in the case shown and can be connected. In the profile housing 27, which is open at the bottom, a toothed belt 28b is guided over two deflection rollers 28, each of which is mounted in a pivot bearing 28c on vertically aligned pivot axes 28a. One of the two deflection rollers 28 is driven by a rod-shaped motor 2a. Both the deflection rollers 28 and the drive motor 2a can be inserted into the housing 27 and fixed in the desired position with clamping screws. For this purpose, the profile housing 27 has a sliding guide 27c running in the longitudinal direction of the profile on its upper horizontal leg 27b. The advantage of this is that the position of the deflection rollers 28 can be optimally adjusted on site to the opening width of the door.

The driver bracket 25 fixed to the roller carriage 6 engages in the motor and control module 2. In order to enable access inside the housing 5, both the vertical leg 63b of the drive module 1 and the vertical leg 27a of the motor and control module 2 are shortened. The essentially horizontal driver bracket 25 is attached to the toothed belt 28b in the conventional manner via clamp connections 29. The driver 25 of the first sliding wing 10 engages under the toothed belt 28b and the deflection rollers 28 and is connected on the opposite side with its vertically bent end 25b to one strand of the toothed belt 28b. A second wing 10 moving in the opposite direction is connected in the same way to the other strand of the toothed belt 28b, but without reaching under the deflection roller 28. The profile housing 27 is provided with a cover hood 5, which is described below. The fastening options on the drive module 1 were already described at the beginning.

The following applies to the carrier module 3 shown in Figure 1 : The carrier module 3 has a profile housing in the same way as the modules 1 and 2 described above. Two hollow profile chambers are formed in it. Flat material can be accommodated in both chambers for the supporting function. The dimensioning of the flat material depends on the stability requirements. In one of the chambers, a display and/or communication device can also be introduced instead of the flat material. The chamber is also particularly suitable for accommodating sensors for controlling the drive. The carrier module 3 can also be arranged adjacent to the drive module 1, deviating from the illustration in the figure. In addition to or as an alternative to the carrier module 3, the module 1 can also be screwed to a stationary carrier or to the wall, as indicated in the figure. The support and fastening can be carried out in accordance with Figures 6 to 11.

A separate display and communication module 4 can be arranged on the outer front of the entire unit as shown in Figure 1 .

The entire unit can be covered by a cover hood 5 (Fig. 1) that is U-shaped in cross section. Predetermined breaking points 5a or markings are provided in the U-legs of the hood 5 in order to be able to easily adapt the dimensions of the hood 5 to the overall arrangement.

An alternative design of the cover 5 is shown in Figure 2. The cover 5 has a vertical leg 5b and a horizontal leg 5c and is attached to the front of the motor and control module 2. For this purpose, the module 2 has a horizontal groove 51 near its upper edge, which accommodates partially sleeve-shaped plastic elements 52 at regular intervals. A horizontal web 53 with a spherical free end 54 is attached to the vertical leg 5b of the cover 5 near its upper edge. This spherical end 54 is clipped into the groove 51 under pressure and fixed by the tension of the plastic elements 52. At the free end of the horizontal leg 5c of the cover 5, a fastening option 65 for sealing brushes 66 can be provided as shown.

Using the same modules, drives can be created for different door types, e.g. for single-leaf and double-leaf sliding doors. Telescopic sliding door drives can also be created, e.g. by using two drive modules 1 parallel to each other (Figure 12). Sliding doors in escape and rescue routes can also be built using the modules. So-called break-out sliding leaves can also be used here using a suitably modified drive module or a separate break-out module. Folding door drives can also be built using a special or supplemented drive module.

In the embodiment in Figure 5, a U-profile housing 41 is provided which is open at the bottom. The drive module 1, the motor and control module 2 and the carrier module 3 are arranged in the U-housing. Instead of these modules 1, 2, 3, which are complementarily adapted to the interior dimensions of the U-housing 41, conventional units of a sliding door drive can also be attached and arranged in it. In comparison to conventional drives, which generally have an L-shaped carrier, the U-housing provides more attachment surfaces and a concealed receiving chamber, so that a separate cover panel can be omitted, especially if the sliding leaf 10, as shown in Figure 4, engages with an upper horizontal edge in the interior of the U-housing 41.

The entire drive unit can be integrated into a conventional transom of the mullion-transom facade, e.g. pushed in there. Alternatively, the entire drive unit can be attached to the mullion or the transom, as shown in Figures 1 and 2, for example. The drive unit can also replace the conventional transom, whereby the connection of the facade cladding or glazing can be made via conventional connection elements that are attached to the drive unit replacing the transom.

The embodiment shown in Figures 13 and 14 is a modification of the embodiment in Figure 2. The corresponding

In the appropriately constructed drive module 1, the motor and control units, e.g. drive motor 2a, control 2f, as well as other elements shown in the following figures such as the radar, the deflection pulley, a socket, the transformer and the locking mechanism are fastened in a receiving groove 350 arranged on the front of the box-shaped drive housing 63 via clamping blocks 351 with clamping screws 352. The additional suspension device 33 on the upper edge of the drive housing, as in the embodiment in Figure 2, is omitted. The receiving groove 350 is essentially T- or C-shaped. It lies horizontally in the middle area of the front of the drive housing 63 on its vertical leg 63b. The drive units and all other components can be inserted one behind the other in the receiving groove 350 and are each individually fastened via a clamp fastening 352. Alternatively, several horizontally running receiving grooves can be arranged in the front. Likewise, the receiving groove 350 in the middle area of the drive housing 63 can have several recesses that allow clamping blocks 351 to be inserted at these points. This is particularly advantageous if additional components are to be added or replaced later. Furthermore, the clamping blocks 351 can be designed in such a way that they can be inserted into the receiving groove 350 at any point and only engage behind the ends of the groove 350 when rotated by 90 degrees.

The drive and control units clamped in the receiving groove 352 are covered by a U-shaped cover 5, which forms an essentially cuboid-shaped receiving space 55 for the drive units. The toothed belt 28b is guided in the receiving space 55 in a lower horizontal plane with the deflection roller 28 (Figure 15) and drive wheel 2c (Figure 19). Above this plane, the motor 2a, the control unit 2f, a battery pack 2g, a cable duct/cable holder 2h, a transformer pack 220 (consisting of two transformers 240 connected in series or parallel) and the locking mechanism 9 are arranged in the receiving space 55.

In the sectional view of Figure 13, of all the drive and control units mounted in the front receiving groove 350, only the control unit is shown.

&Zgr;.&Oacgr; »» * ·&bgr;

control unit 2f can be seen. It has an elongated box-shaped design and is arranged directly above the drive belt level. The control unit 2f consists of an upper housing part 270, which accommodates the control boards (not shown) and is clamped in the front groove 350, as well as an L-shaped cover 271 which is plugged onto the upper part 270 from below. The control boards are inserted from the side into two corresponding horizontal insertion grooves 272 within the upper part 270. This allows for subsequent retrofitting of additional boards in a simple manner. When the cover 271 is removed, all electronic components are directly accessible. The side surfaces of the control unit 2f remain uncovered.

Below the left insertion groove 272, a heat sink 273 with several cooling fins is integrated in the upper part of the housing 272 in order to be able to dissipate the heat generated by the control boards more quickly.

The drive belt 28b is shown below the control unit 2f, as well as the drive bracket 25 connected to the first door leaf 10. Because the right leg 63b of the drive profile 63 ends at the level of the central web 64b, the drive bracket 25 can be guided horizontally from the upper edge of the leaf to the drive belt 28b. The upper edge of the leaf is in the drive belt plane. The drive bracket 25 runs just above the lower leg of the cover 5. On the leaf side, it is screwed to the base plate 75 (Fig. 7) pushed into the upper edge of the leaf, to which the suspension and adjustment device 7 is attached. On the drive belt side, the driver bracket 25 has an upwardly bent end 25b, which is screwed to a counterpart 28c, whereby the drive belt 28b, which is split at this point, is clamped between the bracket end 25b and the counterpart 25c. The drive belt 28b is split twice at the fastening point of the driver bracket. This allows the height to be reduced, since the screw connection of the bracket end 25b and counterpart 25c is no longer above the drive belt, but is located directly in the drive belt plane.

Figure 14 shows the driver bracket 25 of the second wing 10 and the deflection roller 28 behind it. The driver bracket 25 is guided horizontally from the upper edge of the wing under the front drive belt 28b and engages with a U-shaped end in the drive belt plane. The middle part of the U-shaped end has an adjusting device 25d, by means of which the bracket length can be adjusted. The bracket end 25b is also screwed to a counterpart 25c and clamps the toothed belt 28b which is split at this point.

In an alternative embodiment, the carrier bracket 25 can also be guided above the drive belt 28b. This makes it possible to lower the drive belt level overall. This creates additional installation space in the areas of the receiving space 55 in which the bracket is not guided.

Above the drive belt level in Figure 14, the cable duct 2h is arranged, which is also clamped into the front groove 350 of the drive module 1. It has an overall rectangular shape and is functionally divided into two parts. The left half 250 is enclosed on all sides except for an insertion opening 251 on the vertical front side and is used to guide loose cables. The right half 252 is open at the bottom and has insertion grooves 253 running lengthways on the top for accommodating functional components. For example, a battery pack 2h is shown, which is attached via a screw connection 261 to a bracket 260 that has been inserted horizontally into the insertion grooves 253 of the cable duct 2g.

At other points in the cable duct 2g, connector strips for connecting external control components can be accommodated in the insertion grooves 253. It is also possible to arrange a busbar instead of wiring.

The following generally applies to the embodiments shown in Figures 13 to 20 : The cuboid-shaped receiving space 55 formed by the U-shaped cap 5 adjoins the box-shaped drive profile 63 of the drive module 1, with the upper horizontal edge of the receiving space or cap 5 being flush with the

upper horizontal edge of the drive module 1 and the lower horizontal edge of the receiving space or the cap 5 is also aligned with the lower edge of the vertical leg 63a of the drive module 1 and the lower edge of the vertical leg 3b of the carrier module 3. The cross section of the receiving space 55 is rectangular and arranged so that the horizontal edge is longer than the vertical edge, preferably 1.5 - 2 times as long.

The cross-section of the running gear 63, in which the roller carriages including the suspension and adjustment device 7 for the wing 10 are arranged, is essentially square, with the vertically extended leg 63a being approximately the same length as the horizontal edge of the running gear cross-section.

A recess 7a is formed between the vertical leg 63a and the box-shaped housing part that accommodates the carriages 6, in which the suspension and adjustment device 7 and the upper edge of the wing 10 are arranged so as to engage. The recess 7a is open towards the receiving space 55 due to the shortened leg 63b on the right in the figure, so that the driver 25 can reach through.

The entire drive, consisting of carrier module 3, drive module 1 and drive units, is thus rectangular in shape, with the long edge arranged horizontally and the short edge arranged vertically. The upper edge of the wing 10 engages in this rectangular drive box, so that the upper edge of the wing 10 is covered at the front by the front of the drive or the cover 5.

In modified versions, the drive module 1 can be designed in such a way that the rollers 69 and/or the carriages 6 are arranged laterally offset from the wing 10 and the lower edge of the rollers 69 is arranged below the upper edge of the wing 10, preferably the axis of rotation of the rollers is arranged below the upper edge of the wing. The rollers 69 can be mounted separately or directly in the wing 10 or in separate roller carriages 6 that are connected to the wing 10, in the area where the rollers 69 or roller carriages 6 are arranged, the wing thickness can be reduced. In this version

In the example shown, the rollers 69 preferably run in an open, e.g. L-shaped, guide rail, but versions with a closed box-shaped guide rail are also possible, e.g. enclosing the upper edge of the sash 10 on both sides.

Figure 15 shows a sectional view of the receiving space 55 delimited by the cover 5 in the plane of the deflection roller 28. A downward-pointing, almost L-shaped holding arm 28d supporting the deflection roller 28 is clamped with its vertical leg by means of clamping screws 352 in the front groove 350 on the drive module 1. The horizontal leg of the holding arm carries the vertical axis of rotation 28a of the horizontally positioned deflection roller 28. The deflection roller 28 is mounted on its axis of rotation 28a via a pivot bearing 28c. The toothed belt 28b guided on the deflection roller 28 is also shown.

The horizontally running T-shaped groove 350 is arranged approximately centrally on the front side of the vertical leg 63b of the drive housing 63, whereby it extends over the entire length of the professional housing 63. On both sides of the groove 350, a narrow projection 354 is formed on the vertical leg 63b. The clamping block 351, which is also T-shaped and is accommodated in the groove 350, has a threaded hole 353 and protrudes from the T-groove 350. The holding arm 28d, which carries the deflection roller 28, rests flat on the projection 354, whereby the end of the clamping block 351 protruding from the groove 350 is accommodated in a recess in the holding arm 28d. A clamping screw 352 is guided through the holding arm 28d and engages in the threaded hole 353 of the clamping block 351 and rests with its screw head 352a on the holding arm 28d.

The clamping screw 352 pulls the clamping block 351 with its T-shaped end from the rear to the projection 354, which closes off the groove 350 at the front, while at the same time the holding arm 28d is pressed against the projection 354 from the front. The clamping block 351 and the holding arm 28d are thus firmly connected to one another and secured against further displacement. All other drive and control elements are clamped in the groove 350 in the same way.

The sectional view of Figure 16 shows the radar 220 for controlling the door. The housing 222 of the radar 220 is attached to the underside of the vertical leg of an upwardly pointing, almost L-shaped support arm.

221 is secured by a screw connection 224. The holding arm 221 is also clamped in the front groove 350 on the drive module 1. On the housing

222 is arranged the sensor 223, which can be pivoted about a horizontal axis and engages in the drive belt plane between the two toothed belts 28b. In order to allow the sensor 223 a clear view of the door vestibule, the cover 5 has a recess 500 below the radar 220.

In Figure 17, the left outer end of the door drive is shown in three different perspectives. Figure 17a shows a view from below, Figure 17b a front view and Figure 17c a section along line XVU-XVII in Figure 17a. In addition to the drive module 1, the carrier module 3, the cover 5 and the side part 510, Figures 17a to 17c show the left-hand buffer 610 for the roller carriage 6, a socket 230 for connecting the power supply and one of the clamping pieces 35 for connecting the carrier module 3 and the drive module 1.

In Figure 17a, the side part 510 is attached to the side of the running module 1 via a first screw 511 and to the carrier module 3 via a second screw 512. The side part 510 has a rectangular basic shape and has a recess 515 below the running module 1, which extends to the level of the center webs 64a, 64b and allows the roller carriage 6 to be moved to the end of the rail without the wing 10 striking the side part 510 (Figure 17c). The carrier module 3 and the side part 510 are flush with each other at their vertical edge, as are the side part 510 and the cover 5. The height of the side part 510 is identical to the height of the drive module 1, the carrier module 3 and the cover 5. The side part 510 also serves as a seat for the cover 5. For this purpose, the side part 510 has locking points 516 in the middle area of the horizontal edges, onto which the cover 5 is attached from the front.

A retaining button 513 attached to the inside of the side part 510 serves to fasten a retaining strap connected to the cover 5, which is clamped into a slot 513a within the retaining button 513 for this purpose. On the other side, the retaining strap is screwed to the cover 5 or fastened with a clamping piece in a horizontal groove within the cover 5. The horizontal groove can also be a dovetail profile. If the cover 5 is removed from the side parts 510, for example when servicing the system, it hangs on the two retaining buttons 513 of the side parts 510 via a left-hand and a right-hand retaining strap. When the cover 5 is closed, a pin 514 near the front vertical edge of the side part 510 supports the winding up of the retaining strap.

The right-hand side part 510 shown in Figure 19 is identical to the left-hand side part 510 shown here. Figure 20 also shows a retaining bracket 520, which additionally supports the cover hood 5 in the middle. In addition to the support provided by the side parts 510 and the retaining bracket 520, the cover hood 5 rests with its upper horizontal edge on a narrow shoulder 630 on the upper front edge of the drive module 1.

The socket 230 for connecting the power supply is screwed to a base plate 232 arranged vertically in front of the drive module 1 using two screw connections 231 (Figure 17c). The base plate is in turn fastened to the receiving groove 350 arranged on the front of the drive module 1 using clamping blocks 351 and a clamping screw 352. Figure 17a also shows the power plug 233 plugged into the socket 230 with the on/off switch 234 on the front.

Figure 18 shows the two transformers 240 in a view from below, in a front view and in a sectional view along line XVIII-XVlll in Figure 18b. The two transformers 240 are arranged next to each other in front of the drive module 1 and are enclosed by the cover 5, whereby only a small clearance remains between the transformer 240 and the cover 5. By using two transformers 240 instead of a single

The height can be reduced individually. The two transformers 240 can be connected in series or in parallel. This results in greater flexibility for supplying drive motors of different dimensions. These are preferably toroidal core transformers.

In the front view in Figure 18b, the right of the two transformers 240 is shown cut open. The screw connection 241 can be seen, with which the transformer 240 is screwed and secured onto the horizontal leg 242a of an L-shaped base plate 242. The vertical leg 242b is, as shown in Figure 18c, fastened in the receiving groove 350 arranged on the front of the drive module 1 via clamping blocks 351 with clamping screws 352.

Figure 19a shows a view from below of the right-hand end of the drive module 1 with the motor 2a, the gear 2i and the drive pulley 2c for the toothed belt 28b, which is directly coupled to the gear 2i of the motor 2a. Because the drive wheel 2c is mounted directly on the output shaft of the gear 2i, a separate bearing block is saved. The right side part 510 shown, which covers the drive module 1 and the carrier module 3 at the sides, is designed identically to the left side part 510 already described in Figure 17.

The motor 2a is essentially rod-shaped and arranged in the longitudinal direction of the drive. Including the drive disk 2c, the motor 2a takes up the entire installation space between the drive module 1 and the cover 5, as can be seen in the sectional view of Figure 19c along line IXX in Figure 19a. The drive disk 2c is aligned horizontally and arranged below the motor 2a.

The drive unit with motor 2a and drive pulley 2c is attached to a tensioning device 370, which enables tensioning of the toothed belt 28b by moving the complete drive unit on the tensioning device 370 in the longitudinal direction of the drive. The tensioning device 370 consists of a stationary abutment 371 and a slide 372 that can be moved in the longitudinal direction of the drive. The abutment 371 is fixed in the

clamped to the front groove 350 on the drive module 1. The carriage 372 is simply placed on the front groove 350 with an angled arm (Figure 19c) and guided in it. The carriage 372 is held in the groove 350 by a clamping claw 376, which rests on the angled arm of the carriage 372 guided in the groove 350. In front of and behind the carriage 372, a conventional clamping block 351 is connected in the groove. The complete drive unit with motor 2a, gear 2i and drive disk 2c is mounted on the carriage 372. The clamping claw 376 is attached to the two clamping blocks 351 by two clamping screws 352, with its downwardly bent ends gripping the clamping blocks 351. When the clamping screws 352 are loosened, the entire unit consisting of clamping blocks 351, clamping claw 376 and slide 372 can be moved along the groove 350. The clamping claw 376 then rests on a threaded pin 373 protruding longitudinally from the abutment 371 under the tensioning effect of the drive belt 28b.

To tension the drive belt 28b, first the two clamping blocks 351 are inserted at the corresponding point in the front groove 350. The carriage 372 with the drive unit is placed on the groove 350 between the clamping blocks 351 and then the clamping claw 376 is screwed onto the clamping blocks 351, but without tightening the screw connection. The clamping claw prevents the carriage 372 with the drive unit attached to it from jumping out of the groove 350, but the entire arrangement including the drive unit can still be moved in the longitudinal direction of the drive. The drive belt 28b can now be roughly pre-tensioned by moving the entire unit. Then, next to the left of the two clamping blocks 351, the abutment 351 is mounted in the front groove 350, whereby the clamping claw 376 is supported on the threaded pin 373 protruding from the abutment 371. For fine adjustment, the threaded pin 373 is then simply screwed further out of the abutment 371, whereby the threaded pin 373 pushes the clamping claw 376 together with the chute 372 and the clamping blocks 351 in the groove 350 in front of it and further tensions the drive belt 28b. In order to enable the threaded pin 373 to be turned, the threaded hole 375, which accommodates the threaded pin 373 in the abutment 371, is on the plain bearing 372

facing away from the outside. The threaded pin 373 can be fixed in place using another clamping screw 374 after the optimal position has been reached. If the drive belt 28b has sufficient tension, the clamping bracket 376 is clamped with the clamping blocks 351 in the front groove 350 by tightening the clamping screws 352, whereby the slide 372 guided in the groove 350 below the clamping bracket 376 is fixed together with the drive unit. The abutment 371 is then no longer required for further support.

Alternatively, the stand-alone deflection roller 28 on the other side of the drive 1 can also be adjusted with the help of the abutment 371 in order to tension the drive belt 28b.

In the drive module 1, the buffer 610 is shown in dashed lines, which prevents the roller carriage from running into the side part 510. The buffer 610 is accommodated in receiving grooves 612 on the undersides of the center webs 64a, 64b (Figure 19c). The square base body 613 fastened in the receiving grooves 612 has an arm 614 that projects vertically into the upper chamber 6a of the drive profile 6 and is secured against displacement relative to the top of the drive 63 by a clamping screw 611. Facing the roller carriage (not shown), an elastic damper 615 is attached to this vertical arm 614, which dampens the roller carriage from running into the side part 510.

In addition to the locking device 9, Figure 20a also shows the radar 220, one of the two drivers 25, the retaining bracket 350 and the roller carriage 6 together with the wing 10 attached to it. The figure shows a view from below in the middle area of the drive module 1.

The driver 25 coupled to the outer strand of the drive belt 28b is shown without the adjustment option 25d. Its outer end is connected to the counterpart 25c by a screw connection 25e and clamps the two ends of the drive belt 28b split at this point. The wing-side end of the driver 25a is connected to the base inserted in the upper side of the wing.

In addition to the fastening of the driver 25, the screw fastening 76 of the bracket 74 can be seen on the base plate 75. The wing 10 and the roller carriage 6 are indicated by dashed lines in the figure.

Also clearly visible in this figure is the recess 620 in the drive profile 63, which is used to insert the roller carriage 6. The recess 620 is secured on both sides by buffers 610 during operation.

The radar 220 already described in Figure 16 will not be explained in more detail here. In addition to the radar 220, the retaining bracket 520, which supports the cover 5 in addition to the side parts 510, is clamped in the front groove 350 by means of clamping screws 352.

The locking device 9 is clamped in the front groove 350 by means of a holding arm 91 offset to the side and angled, also by means of clamping screws 352.

Figure 21 shows an overall overview of the components shown in Figures 13 to 20 in order to give an impression of their arrangement on the drive module 1. From left to right, the following elements are shown: side part 510, socket 230, transformer 240, deflection roller 28, cable holder 2h with battery pack 2g, locking mechanism 9, radar 220, retaining bracket 520, control unit 2f, tensioning device 370, drive pulley 2c, motor 2a and second side part 510. In the drive module 1 itself, which is attached to the carrier module 3, four buffers 610 and the central recess 620 can be seen.

Finally, Figure 23 shows a cover panel 530, which covers the drive module 1 if no drive and control elements are mounted, as is the case with non-automatic sliding doors, for example. The cover panel 530 has a convexly curved front side and is fastened in the front groove 350 of the drive module 1 by means of clamping blocks 351 and clamping screws 352. The upper horizontal edge of the

Cover panel 530 is flush with the front upper horizontal edge of the drive module and the lower horizontal edge of the cover panel 530 is level with the lower edge of the vertical leg 63a of the drive module 1. The width of the cover panel 530 corresponds to the width of the drive module 1.
