Description

Drive device for a movable wing of a window or door as a sliding wing or a movable lifting sliding wing

Technical Field

The invention relates to a drive device for a movable wing of a window or door as a sliding wing or a movable lift-type sliding wing according to the preamble of claim 1.

Background

Movable wings for windows or doors as systems of push-pull wings or lift-type push-pull wings usually have a relatively high mass. When moving the wing, in particular from its upright position, a high force must be applied to open the wing. While closing must also exert a resistance against the weight of the wing. The known drive devices are visually fitted on windows or doors and are protected by means of an additional covering body, which impairs the appearance considerably. The visible components lying disturbingly likewise increase the risk of damage during assembly. Furthermore, the visible components provide more possibilities for manipulation from the outside. It has proven itself from the known prior art that the assembly of such a drive is likewise costly.

Furthermore, drive devices arranged flat on the cover are known, which, however, are associated with only high costs and can only be integrated into less suitable profile systems. It has proven to be particularly expensive to mill in the profile and can lead to high costs and to a weakening of the structure of the window or door element.

A sliding window or sliding door with a protective frame in which at least one sliding leaf is held displaceably is known from EP2063058B1, which sliding leaf is displaceable by means of a drive and can be connected to the protective frame by means of a closure device, wherein the sliding leaf has four frame profiles fixed to one another. The drive device comprises a driven drive roller around which a tensioning element fixed to the protective frame is wound, wherein the tensioning element is guided by two deflection rollers and enters the cavity of the frame profile.

Due to the vertical installation in the vertical beams of the wing, the current control devices can only be realized by steering to the guide rails, which complicates the installation at high costs and accordingly requires a lot of installation space in the wing. In addition, the components of the control device and the guide rail are distributed at a large distance from one another, which makes assembly difficult due to the individual component assemblies.

Further, EP1914372A2 is indicated. In this case, a passenger door of a motor vehicle for public transport of passengers, which is designed as a sliding door or a pivoting sliding door, is provided with at least one door leaf which is displaceable in its longitudinal direction and which is suspended in a supporting guide and is guided displaceably. For this purpose, the support guide has a linear guide with at least one guide rail, on which a guide carriage is guided and from which the door leaf is suspended by means of a support arm. The load guide cannot be installed in a window or door system covertly due to the design. Furthermore, this design is complicated to assemble and expensive to manufacture with numerous components.

Disclosure of Invention

The object of the present invention is therefore to eliminate the known disadvantages and to provide a drive for a movable wing, which is used as a push-pull or lift-type push-pull wing, which has a greater load-bearing capacity and is optimally guided for windows or doors, at low cost and in a small installation space, and which can be fitted, calibrated and removed in a simple, rapid, reliable and precise manner even afterwards.

This object is achieved by a drive device for a movable wing of a window or door as a sliding wing or a movable lifting sliding wing having the features of claim 1.

The drive is arranged such that it is suitable for a movable wing of a window or door as a push-pull wing or a movable lift-type push-pull wing. In order to extend parallel to the wing in one direction on the rail or to move along the rail, the movable wing has at least two work carriages each having a roller. For the automatic movable actuation of the wing, a control element with a switched control drive is preferably arranged on the vertical beam. By actuating the actuating element, the movable wing can be moved, for example, from a closed position into a position opposite a fixed protective frame and a fixed door region of a mounted wing. On the other hand, the wing can also be brought thereby into a reliable moved ventilation position or into the region of the through-opening. The wing is advantageously held movably on the protective frame by a working carriage on the underside on a rail.

It is likewise conceivable to actuate the drive via a remote control unit or a smart home system. For this purpose, the control unit can be arranged on a window or a door. The control unit can likewise be arranged in a wall of a building and be connected to the operating element and the drive via control lines.

In addition, the actuating element can control a drive arranged on the vertical beam in the closing direction toward the front, which likewise moves the locking device on the vertical beam into the closed position of the locking of the wing or into the open position of the unlocking. It is also conceivable to perform manual actuation by means of an actuating handle which transfers the actuating lever to the locking device.

In order to be able to subsequently move the movable wing by means of the drive, in a system for a movable lift-type push-pull wing for windows or doors, the movable wing can be moved by means of the drive from a closed position by means of the actuating element, automatically or by means of a manual actuating handle, by means of a coupled connection of a control lever, onto the work carriage and into an elevated open position.

The two operating variants described above, which can be selected as required and are identical to the features of the hybrid system, can likewise be arranged in windows or doors. The additional drive means selected for the system are also connected to the control line and to the control unit.

In order to be able to realize the position of the wing relative to the fixed protective frame and relative to the fixedly mounted wing or the fixed door region, special fittings, so-called systems for push-pull wings or movable lift-type push-pull wings, are provided between the movable wing and the fixed protective frame.

The drive device for moving the wing advantageously comprises a drive motor arranged on the wing side, which has a threaded spindle driven on the drive motor. The threaded spindle is guided forcibly around a rack element arranged on the protective frame. The covering, lying arrangement of the drive device is achieved by the drive device in the installed position of the movable wing fitting almost completely in the recess or receptacle of the horizontal beam above the movable wing and in the guide rail provided on the protective frame. In order to optimally support the drive member of the drive, the drive motor and the threaded spindle are mounted as a single structural unit in a housing.

The rack element is almost completely surrounded by the guide rail. The slot in the guide rail forms an opening and thereby forms a possibility for a connection between the component on the wing side and the component on the protective frame side of the drive.

A feature which has proven to be cost-effective and which has advantages in terms of construction is that, for the rotational transmission of the movement, the drive motor and the threaded spindle are drivingly connected together in the longitudinal direction relative to the direction of movement of the wing by a positive connection of a flexible or cardan shaft.

The drive motor and the threaded spindle are arranged vertically and longitudinally to the housing and are arranged offset relative to the recess or receptacle of the movable wing, wherein the drive motor faces the floor of the housing and thereby the base of the recess or receptacle, and the threaded spindle is spaced apart from the base in the direction of the rack element. As a result of the displacement of the component of the drive motor and the threaded spindle over the interior height of the housing, the drive motor reaches as large a structural space as possible in the housing, wherein the threaded spindle, in order to interact with the rack element, obtains the necessary free space for the thread pitch to be unwound.

By arranging a latching section, which can be snapped into a recess of the housing in a force-fitting manner, below the drive motor on the side facing the base plate of the housing, a simple engagement and a simple assembly of the drive member in the housing is achieved. For this purpose, an elastic latching projection comprising a slide-in ramp is mounted on the outer side of the latching section, adapted to a groove on the housing. In the assembly, the latching projections engage with a slight spring force in the recesses of the housing and form a detachable connection with the housing. The drive motor and the threaded spindle with shaft and carriage can be positioned fixedly in the housing as a complete structural unit, preassembled, by means of the latching section. The housing allows a reliable accommodation and fixing of the drive motor and a satisfactory support and protection of the threaded spindle from contamination and damage. The complete structural unit can thereby be easily accessed at the same time and can also be replaced if required. In addition, the locking segment is mounted movably in a groove of the housing. The groove is configured as an elongated hole for this purpose. By means of the movable mounting of the drive means (including the drive motor, the threaded spindle with the shaft and the carriage) in the recess by means of the latching section, tolerances which can occur and the adjustment of the wing in height to the protective frame, in particular in the case of a lifting push-pull wing, can be compensated by the flexible shaft.

The movable wing comprises four beams which are constructed as hollow profiles, in particular as aluminum profiles or plastic profiles or as solid wood profiles. The beam comprises prefabricated recesses or receiving grooves for the covering assembly of fitting components, in particular for the drive device. In this way the drive means in the upper horizontal beam and directed towards the vertical beam fit into the groove or receiving groove. Preferably, the wing-side component of the drive is configured to fit in the height H and width B of the recess or receptacle groove of the horizontal beam above the wing. There is therefore no additional work step for mounting the drive on the wing.

In a preferred embodiment, the housing is designed with a U-shaped cross-sectional profile, wherein the individual side walls differ in height from the base over the length of the housing. The side walls of the strip-like structure differ in height by functional, supporting or protective features. The maximum height of the housing is reached at the bearing point of the threaded spindle.

For simple fixing, the drive in the movable wing is detachably fixed in the receiving groove. In this case, the end of the respective long side of the housing is connected to the limiting and fixing element fixed to the wing in a form-fitting and/or force-fitting manner. The housing forms a one-piece component together with a fan-side component of the drive device, which is guided from the open end of the upper horizontal beam of the movable fan into the recess or receptacle groove. One end of the housing is connected to a limiting element which is fixed in a force-fitting manner in the recess or the receiving groove by means of a fixing screw in a form-fitting manner in a horizontal and vertical fixed position. The other end of the housing is held in a horizontal and vertical movement position over the entire surface by a further fixing element, wherein the fixing element of the vertical beam pointing to the wing has a circular support body with a hole, which fits into a receptacle in a form-fitting manner, which is arranged on the upper horizontal beam below the recess or receptacle, and the support body is connected to the movable wing in a force-fitting manner by means of a fixing bolt.

For simplified assembly and cost-effective production, on the fixed part arranged at the free end of the upper horizontal beam, running wheels are provided which are mounted transversely in the direction of the guide rail and are separated by grooves or recesses of the movable wing, said running wheels being movably arranged in laterally arranged transverse guides of the guide rail. A further running wheel which is fixed to the wing in a form-fitting and/or force-fitting manner is preferably also provided at the other end of the upper horizontal beam. The running wheels fixed on the wing contribute to a reliable and movable support towards the upper horizontal area of the movable wing of the protective frame. Instead of ball-bearing running wheels, height-compensating sliders or other components can also be used for guiding the wing.

In order to reliably receive the carriage and the threaded spindle, two mutually remote struts of the housing extend from the base plate in the direction of the rack element to the maximum height of the housing up to almost the same height of the carriage.

The drive motor is connected to the driven rotatable shaft by a coupling, and the shaft is in turn connected to a threaded rod of the threaded spindle, which is rotatably mounted about the positionally fixed carriage, which has proven to be simple and cost-effective in design. In contrast, the rotationally fixed carriage in the housing can be displaced along the guide rail. For this purpose, the threaded spindle is connected in an effective rotational manner to the rack element by means of a thread. At each end of the extension of the central shaft, the threaded spindle is configured as a cylindrical round rod.

The carriage is preferably made of two mold halves which form a square or rectangle in cross section by means of a positive and/or non-positive connection. In order to achieve the largest possible installation space for the thread of the threaded spindle, the carriage has a window-shaped opening on each side, into which the thread of the threaded spindle projects. The diameter of the thread protrudes through the opening to the wall surface of the outer side of the housing. The opening may additionally function as a safety against unintentional movement of the threaded spindle.

For simple connection of the threaded spindle, the respective ends of the half-moulds of the carriage have semicircular cutouts which, by engagement, form circular cutouts for cylindrical round bars supporting the threaded spindle for the rotational movement of the thread.

In order to be connected in a sliding-guided manner to the protective frame in the longitudinal direction of the guide rail of the movable wing and thereby to connect the wing-side component of the drive device in a sliding-guided manner to the component of the rack element on the protective frame, a guide carriage is formed on the outer side of the carriage facing the rack element. By means of the arrangement of the guide carriages above the thread of the threaded spindle, the rack elements located between the guide carriages engage in through slots for cooperation with the threaded spindle.

To simplify the assembly, all component parts of the drive are assembled before being inserted into the housing and the guide rail. It is believed that the modular connection of the components of the structurally identical toothed segment to one another is a simple operation of fitting the rack element into the guide rail, the toothed segment being insertable into the profile groove or channel of the guide rail both from the open side and through the opening of the guide rail which is configured in a U-shape in cross section. In order to insert the tooth segment through a slot-like opening extending over the entire length of the guide rail, the tooth segment is configured separately in profile and length.

The tooth segments are preferably made of plastic or injection-molded by an injection molding process and are T-shaped in cross section. The T-shape is produced by shaping the profile groove of the guide rail. In the inserted state, the tooth segments in the interior of the profile recess rest in bearing contact with the shaped guide surface.

By means of the object of holding the tooth segments in one piece and being produced cost-effectively, the tooth segments are inclined laterally by an angle for assembly by means of slot-like openings of the guide rail, which are connected in a modular manner to the respective tooth segments, and have diamond-shaped feet which are stepped at the respective ends. Since the angled flanks are matched to the length of the tooth segments, it is possible to fit the tooth segments through the openings into the longitudinally displaceable rear-acting position of the guide rail by means of their rotational position, which is slightly offset relative to the longitudinal direction of the guide rail and thus relative to the slot-shaped openings.

As soon as the other tooth segment reaches the longitudinally displaceable rear-acting position in the profile groove of the guide rail, the tooth segment can be connected to the structural unit of the rack element by means of the stepped end.

In this case, the stepped ends of the tooth segments are stepped and have undercuts at the transitions of the steps or steps, so that a positive interlocking connection results as the tooth segments are screwed in. In the effective connection of the inserted tooth segments, a reliable rear-acting position in the profile groove of the guide rail can be achieved.

As the longitudinally extending mounting position, i.e. the final assembled state of the rack element in the profile groove of the guide rail, is reached, the toothed segment is effectively connected to the carriage on the movable wing and to the threaded spindle of the drive. In this case, the tooth segment on the cover surface has a guide rail in the direction of the wing-side component of the drive, which guide rail is in positive-locking, slidably movable operative connection with the guide carriage of the carriage. Furthermore, a threaded-sided projection is provided on the cover surface, which projection fits into the width of a guide carriage of the carriage, converting a rotary movement into a translational movement in operative connection with the threaded spindle in order to move the wing in the longitudinal direction of the guide rail.

The connection of the wing-side component of the drive device by the carriage to the rack element of the drive device, which is arranged on the protective frame, by the guide rail also automatically ensures the final installation position of the drive device for the operational state of the accidental adjustment of the component and the automatic movement of the window or door in the horizontal direction. The drive device can only be removed after the carriage has been separated from the guide track of the rack element from the positive-locking connection.

Detailed Description

Fig. 1 shows a protective frame 4 with a movable leaf 2 and a fixedly mounted leaf or door area 60 adjacent to the movable leaf in a perspective view of a window or door 3. For actuating the movable wing 2, an actuating element 61 with a switch for actuating the drive 1 is arranged on the vertical beam 62. By actuating the actuating element 61, the movable wing 2 can be moved, for example, from the closed position in fig. 1 into a position not shown according to the arrow direction, opposite the fixed protective frame 4 and the door area 60 fitted in a fixed position, but on the other hand, can also be brought into a reliable moved ventilation position or into the area of the through-opening. The wing 2 is held in this case movably supported on the protective frame 4 on a rail 64 by one or more suspension or working carriages 65, which are located on the underside according to fig. 1.

It is likewise conceivable to actuate the drive 1 by means of a remote control unit or a smart home system. For this purpose, a control unit 67 can be arranged on the window or door 3 according to fig. 5. The control unit 67 can likewise be arranged in a wall of a building and connected to the control element 61 and the drive 1 via a control line 66.

In addition, the actuating element 61 can control a drive, not shown, which is located on the vertical beam 62 at the front in the closing direction and which likewise moves a locking device, not shown, located on the vertical beam 62 into a locked closed position or into an unlocked open position of the wing 2. It is also conceivable to perform manual actuation by means of an actuating handle which transfers the actuating lever to the locking device.

In order to be able to subsequently move the movable wing 2 by means of the drive 1, in the case of a system of a movable lift-type push-pull wing 2 of a window or door 3, the movable wing 2 can be moved by means of a drive, not shown, from the closed position in fig. 1 by means of the actuating element 61, automatically or by means of a manual actuating handle, by means of a lever-coupled connection, onto the carriage 65 and into an elevated open position.

The two operating variants described above, which can be selected as required and are very similar to the characteristics of the hybrid system, can also be arranged in the window or door 3. Additional drives selected for the system are likewise connected to the control line 66 and to the control unit 67.

In order to be able to realize the position of the wing 2 relative to the fixed protective frame 4 and relative to the fixedly mounted wing or the fixed door region 60, special fittings, so-called systems for sliding or lifting sliding wings, are provided between the movable wing 2 and the fixed protective frame 4, wherein for the sake of simplicity only the actuating element 61 on the wing 2 in fig. 1, a part of the running rail 64 for the lower side of the carriage 65 and the upper running rail 10 according to fig. 2 are shown in hidden form.

According to fig. 8, the drive device 1 comprises a drive motor 5 arranged on the wing side, which has a threaded spindle 6 driven thereon. According to fig. 5 and 7, the threaded spindle 6 is guided forcibly around a rack element 7 arranged on the protective frame 4. According to fig. 3, the drive 1 in the installed position of the wing 2 is arranged lying almost completely in a groove or receptacle 8 of an upper horizontal beam 9 of the movable wing 2 and in a covering manner in a guide rail 10 provided on the protective frame 4. The drive motor 5 and the threaded spindle 6 are built into the housing 11 as a single structural unit. The rack element 7 is almost completely surrounded by the guide cross section of the guide rail 10, which forms the cushion. The slot in the guide rail 10 forms an opening and thereby makes it possible to connect components arranged on the wing 2 to components of the drive 1 which are mounted on the protective frame 4.

As is apparent from fig. 8 and 9, the drive motor 5 and the threaded spindle 6 are drivingly connected together in the longitudinal direction relative to the direction of movement of the wing 2 by a positive-locking connection with a flexible shaft 12 or cardan shaft for transmitting the movement in rotation.

In fig. 8, the drive motor 5 and the threaded spindle 6 are arranged axially offset perpendicular to the housing 11 and thus relative to the recess or receiving groove 8 of the wing 2, wherein the drive motor 5 faces the base plate 13 of the housing 11 and thereby the base 14 of the recess or receiving groove 8 according to fig. 3, the threaded spindle 6 being spaced apart by the base 14 in the direction of the rack element 7. With the displacement of the components of the drive motor 5 and the threaded spindle 6 in height, the drive motor 5 reaches as large a construction space as possible in the housing 11, wherein the threaded spindle 6, in order to interact with the rack element 7, obtains the necessary free space for the unwinding thread pitch.

According to fig. 9, a latching section 15 which can be snapped into a recess 17 of the housing 11 in a force-fitting manner is arranged below the drive motor 5 on the side facing the base plate 13 of the housing 11. For this purpose, an elastic latching projection comprising a slide-in ramp is mounted on the outer side of the latching section 15, adapted to the groove 16. In the assembly, the latching projections snap with a low spring force into the recesses 16 of the housing 11 and form a detachable connection with the housing 11. As shown in fig. 9, the drive motor 5 and the threaded spindle 6 with the shaft 12 and the carriage 30 can be positioned in a preassembled manner as a complete structural unit in the housing 11 by means of the locking segments 15. The housing 11 allows a secure accommodation and fixing of the drive motor 5 and a satisfactory support and protection of the threaded spindle 6 against contamination and damage. The complete structural unit can thereby be easily accessed at the same time and can also be replaced if required. By virtue of the fact that the groove 16 in the housing 11 is configured as a slot, the latching section 15 can be moved in the latching position. The movable mounting of the latching segments 15 by means of the transmission via the flexible shaft 12 to the drive motor 5 and to the threaded spindle 6 with the carriage 30 allows compensation of tolerances and adaptation of the lifting push-pull wing 2 to the protective frame 4 in the lifting and lowering movement.

The movable leaf 2 comprises four

beams

9, 22, 62, 63 which are designed as hollow profiles, in particular as aluminum profiles or plastic profiles, or as solid wood profiles. The beams contain preformed grooves or receiving slots for coveringly mounting the fitting components. In this way, the drive means 1 directed towards the vertical beam 22 is arranged in the upper horizontal beam 9. Preferably, the fan-side components of the drive device 1, in particular the housing 11, are configured to fit in the height H and width B of the recess or receptacle groove 8 of the horizontal beam 9 above the fan 2. There is therefore no additional work step for mounting the drive 1 on the wing 2.

In fig. 8, the housing 11 is formed with a U-shaped cross-sectional contour, wherein the individual side walls 17 differ in height from the base plate 13 over the length L of the housing 11. The side walls 17 of the strip-like structure differ in height because of their functional, supporting or protective properties. The maximum height of the housing 11 is reached in the bearing position of the threaded spindle 6.

In order to be able to fasten the drive 1 in the movable wing 2 detachably in the receiving groove 8 in a simple manner according to fig. 1 and 3, the respective long-side ends 18, 19 of the housing 11, according to fig. 7 and 8, form a positive and/or non-positive connection with the limiting and

fastening elements

20, 21 fastened to the wing 2. The housing 11 together with the wing-side component of the drive 1 forms a one-piece component, which is guided from the open end of the horizontal beam 9 above the wing 2 into the recess or receptacle 8, wherein the one end 18 of the housing 11 forms a form-fitting connection with a horizontal and vertical fixed position with a limiting part which is fixed in the recess or receptacle 8 by means of a fixing screw in a force-fitting manner. As can also be seen from fig. 8, the fastening part 21, which is located on the other end 19 and which is arranged facing the vertical beam 22 of the movable wing 2 according to fig. 5, has a circular support body 23 with a bore 24, the support body 23 fitting in a form-fitting manner into a receiving portion which is arranged on the upper horizontal beam 9 below the recess or receiving groove 8 and the support body 23 forming a force-fitting connection with the movable wing 2 by means of a fastening bolt.

According to fig. 1 and 7, at one end of the vertical beam 22 of the movable wing 2, which is directed toward the upper horizontal beam 9, a running wheel 25 is arranged in the receiving groove 8 on the fixing part 21, which running wheel 25 is mounted transversely in the direction of the guide rail 10 and is separated by the groove or receiving groove 8 of the wing 2, said running wheel 25 being movably accommodated in laterally arranged transverse guides 26, 27 of the guide rail 10. Not shown is that at the other end of the upper horizontal beam 9 the wing 2 is equipped with another running wheel which is likewise fixed to the wing 2 in a form-fitting and/or force-fitting manner. The running wheels, which are fastened laterally to the wing 2, contribute to a secure and movable support of the upper horizontal area of the movable wing 2.

According to fig. 7 and 8, two

struts

28, 29 which are remote from one another extend to the maximum height of the housing 11 and end from the base plate 13 in the direction of the rack element 7 at approximately the same height of the carriage 30. The housing 11 forms a receptacle for a carriage 30, in which the threaded spindle 6 is mounted so as to be rotatable in the carriage 30.

The drive motor 5 is connected by a coupling to the driven rotatable shaft 12, the shaft 12 in turn being connected, according to fig. 8 and 9, to a threaded rod of the threaded spindle 6 which is rotatably mounted about the positionally fixed carriage 30. Instead, the rotationally fixed carriage 30 in the housing 11 can be displaced along the guide rail 10. For this purpose, the threaded spindle 6 is connected in an effective manner in terms of rotation to the rack element 7 by means of a thread 34 and is formed as a

cylindrical round rod

31, 32 at each end in the extension of the central shaft.

According to fig. 9 and 10, the carriage 30 is made of two

mold halves

35, 36, the mold halves 35, 36 forming a square or rectangle in cross section by means of a positive and/or non-positive connection. In order to achieve the largest possible installation space for the thread 34 of the threaded spindle 6, the carriage 30 has window-shaped

openings

39, 40 on the respective side faces 37, 38, into which

openings

39, 40 the thread 34 of the threaded spindle 6 projects. The

openings

39, 40 may additionally function as a safety against unintentional movement of the threaded spindle 6.

For simple attachment of the threaded spindle 6, according to fig. 9 and 10, the respective ends of the half-

moulds

35, 36 have

semicircular cutouts

41, 42; 43. 44, the cut-

outs

41, 42; 43. 44 form, by engagement, for the rotational movement of the threaded spindle 6, a circular cutout for supporting the

cylindrical round rod

31, 32.

In order to guide the movable leaf 2 in the longitudinal direction of the window or door 3 within the protective frame 4, a guide carriage 46 is formed on the outer side 45 of the carriage 30 facing the rack element 7. Since the guide carriages 46 are arranged above the threaded spindles 6, the rack elements 7 located between the guide carriages 46 are engaged by the grooves for cooperation with the threaded spindles 6.

All component assemblies of the drive 1 are installed in the housing 11 according to fig. 8 and in the guide rail 10 according to fig. 6 before assembly. In order to facilitate the assembly and installation of the toothed rack element 7 into the guide rail 10 and the protective frame 4 and to connect them in combination with the components of the wing 2 of the drive 1, the toothed rack element 7 is formed according to fig. 7 and 12 by toothed segments 47, which toothed segments 47 can be connected to one another in a modular manner and form a complete structural unit.

According to fig. 12, the tooth segment 47 is preferably produced by injection molding or injection molding, and is T-shaped in cross section according to fig. 14. The T-shape is produced by the shaping of the profile groove 54 and the opening 53 of the guide rail 10. In the inserted state of the tooth segments 47 in the profile recess 54, the tooth segments 47 in the interior of the profile recess 54 lie in bearing contact with guide surfaces 68, 69 formed in each case in the vicinity of the opening 53.

The tooth segment 47 is inclined at an angle W on the side faces 48, 49 for insertion into the guide rail 10 according to fig. 15 and has diamond-shaped feet 50 which are stepped at the respective ends 51, 52. According to fig. 3, the toothed segment 47 is introduced through an opening 53, formed in the protective frame 4 of the window or door 3, of a fixable, C-shaped undercut profile groove 54 of the guide rail 10, through which opening 53 the toothed segment 47 is operatively connected to the carriage 30 on the movable wing 2 and to the threaded spindle 6 of the drive 1. By means of the

flanks

48, 49 of the toothed segment 47, which are inclined at the angle W, according to fig. 12 and 15, it is possible to achieve a position of rotation of the toothed segment 47, which is slightly offset with respect to the longitudinal direction of the guide rail 10, by means of which the toothed segment 47 is mounted in a longitudinally displaceable, rear-acting position of the guide rail 10 via the opening 53.

As soon as the further tooth segment 47 reaches the longitudinally displaceable rear-acting position according to fig. 3 and 6 in the guide rail 10, the tooth segment 47 can be connected by means of the stepped ends 51, 52 to the structural unit according to fig. 7, in which the guide rail 10 is not shown, and to the rack element 7.

In this case, the stepped ends 51, 52 of the tooth segment 47 are stepped according to fig. 15 and have undercuts at the transitions of the steps or steps, so that a positive-locking connection with one another is produced as the tooth segment 47 is screwed in. In the effective connection of the mutually engaging tooth segments 47, a reliable rear-acting position in the profile groove 54 of the guide rail 10 is achieved.

As the longitudinally extending installation position, i.e. the final assembly state of the rack element 7 in the profile groove 54 of the guide rail 10, is reached, the toothed segment 47 is effectively connected to the carriage 30 on the wing 2 and to the threaded spindle 6 of the drive device 1. In this connection, according to fig. 3 and 14, the tooth segment 47 on the cover surface 55 has a guide rail 56 in the direction of the fan-side component of the drive device 1, which guide rail 56 is in a form-fitting, movable operative connection with the guide carriage 46 of the carriage 30. Furthermore, a projection of a threaded flank 57 is provided on the cover surface 55, which in operative connection with the threaded spindle 6 converts a rotational movement into a translational movement in order to move the wing 2 in the longitudinal direction of the guide rail 10.

The connection of the components of the drive device 1 on the wing side by the carriage 30 to the rack elements 7 of the drive device 1, which are arranged on the protective frame 4, by the guide rails 56 also automatically ensures the final assembly position of the drive device 1 in order to cope with the operational state of an accidental change in position of the components and an automatic movement of the window or door 3 in the horizontal direction. The removal of the drive device 1 can only take place after the separation of the carriage 30 from the positive connection from the guide rail 56 of the rack element 7.
