Description

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

The sliding sashes of sliding sash or lift-and-slide sash systems for windows or doors often have a relatively high mass. When the movable sash is moved, especially when pushed from a stationary position, a high force must be absorbed to open the system. Closing the system also requires resistance to the weight of the movable sash. Conventional drives are mounted visibly on the window or door and shielded by an additional cover, which severely impairs the appearance. Visible components also increase the risk of injury during installation. Furthermore, visible components offer more opportunities for external manipulation. Installing such a drive device is also complex, given the current state of the art.

Concealed drives are also known, but these can only be integrated with considerable effort and into only a few suitable profile systems. In particular, the milling effort required in the profile proves to be very high, which can lead to high costs and weaken the structure of the window or door elements.

From the EP 2 063 058 B1 A sliding window or sliding door with a frame has become known, in which at least one sliding sash is movably mounted, which can be moved via a drive and coupled to the frame via locking means. The sliding sash has four frame profiles fixed to one another. The drive comprises a driven drive roller around which a tensioning element fixed to the frame is wound. The tensioning element is guided over two deflection rollers and runs into a hollow chamber of the frame profile.

Due to its vertical installation in a vertical spar of the sash, this control device can only be accessed via a guide rail deflection, which complicates installation and requires a significant amount of space within the sash. Furthermore, the control device components are spaced widely apart from the guide rail, making assembly difficult due to the individual components.

Further reference is made to the EP 1 914 372 A2 . In this case, a passenger door designed as a sliding door or pivoting sliding door is provided for public transport vehicles with at least one door leaf that can be moved longitudinally and is suspended and guided in a support guide. For this purpose, the support guide has a linear guide with at least one guide rail, on which a guide carriage is guided and on which the door leaf is suspended via a support arm. Due to its structural design, the support guide cannot be installed concealed in a window or door system. Furthermore, the design is complex to assemble and, with a large number of components, expensive to manufacture.

Furthermore, the EP 3 775 460 B1 for a door or window. A sliding lift-and-slide sash is held in a frame so that it can be lifted and moved. A drive device has an electric drive arranged on the sash side with a threaded spindle driven by it and is mounted in a housing to move the sash. The drive device is arranged on the frame and is positively guided so that it can be adjusted horizontally about a rack element on the frame. When the sash is installed in the frame, the drive device is positioned almost completely concealed in a recess or receiving groove in an upper, horizontal stile of the sash and a guide rail arranged on the frame and allows vertical movement of the sash relative to the frame, with one side of the drive device facing the frame being connected to the components attached to the frame so that it can be moved horizontally. The drive mechanism connects to the movable sash in a fixed position, allowing horizontal movement of the movable sash along the frame's length while maintaining a constant vertical position relative to the frame. For adjustable adjustment, the rack element consists of individual toothed segments that are mounted and secured in the guide rail through an opening in the guide rail.

The object of the present invention is to eliminate the known deficiencies and, in contrast, to provide a drive device for a sliding sash as a sliding sash or lift-sliding sash for large load-bearing capacities and optimal guidance for a window or a door with low costs and space requirements, which can also be retrofitted and adjusted in a simple, fast, safe and precise manner. can be installed and dismantled, but in particular it further simplifies assembly.

This object is achieved by a drive device with a positioning device for a displaceable sash as a sliding sash or displaceable lift-slide sash of a window or door with the features of patent claim 1 and the method according to claim 10.

The drive device is arranged in such a way that it is suitable for a sliding sash or a sliding lift-and-slide sash for a window or door. The movable sash further comprises at least two carriages, each with rollers, for sliding on a guide rail in a direction parallel to the extension of a stationary sash or door panel or along a guide rail. For automatically sliding operation of the movable sash, an operating element with a switch is provided on a vertical beam, which controls the drive device. By operating the operating element, the movable sash can be moved, for example, from a closed position into an open position relative to a fixed frame and a stationary sash or door panel. On the other hand, the movable sash can also be brought into a secured, displaced ventilation position or into the area of a passage opening. The movable sash is held movable on the frame by means of carriages on the floor, supported on a guide rail.

It is also possible to operate the drive device via a remote control unit or a smart home system.

The operating element can also control a motorized drive located at the front of the vertical beam in the closing direction, which also moves the locking means located on the vertical beam into a locked closed position or into an unlocked open position of the movable sash. Manual operation using an operating handle with transmission of an operating rod to the locking means is also conceivable.

In a system of a sliding lift-sliding sash of a window or door, the movable sash can be moved by the drive via the operating element automatically or via the manual operating handle from the closed position through a coupled connection of the operating rod to the carriages into a raised opening position in order to then be moved by the drive device.

Likewise, both of the above-described actuation variants can be installed in a window or door, which can be selected according to requirements and resemble the nature of a hybrid system. Additional drives selected within the system are also connected to the control and/or power lines and linked to the control unit.

In order to enable these positions of the movable sash relative to the fixed frame as well as to the fixed sash or the fixed door panel, a special fitting arrangement, namely a so-called system for sliding sashes or sliding lift-slide sashes, is provided between the movable sash and the fixed frame.

Advantageously, the drive device for moving the sliding sash comprises a drive arranged on the sash side with a motor and a threaded spindle driven by the motor. The threaded spindle is positively guided around a rack element arranged on the frame, which is positioned in a guide rail attached to the frame of the window or door.

To simplify assembly, all components of the drive device, known as drive elements, are mounted before installation in the guide rail and/or operatively coupled to the guide rail. The modular arrangement of individual, structurally identical tooth segments makes it easy to install a rack element in the guide rail. With short tooth segments, the tooth segments can be inserted individually and one after the other into a profile groove or channel in the guide rail through a widened recess in an opening in the guide rail, which has a T-shaped cross-section. To insert the tooth segments through the widened recess, which is located in the slot-like opening extending the entire length of the guide rail, the recess is specially designed to adapt in width and length to the tooth segment and the other drive elements of the drive device that can be mounted in the guide rail.

For this purpose, the profile groove in cross-section has a bottom wall, two side walls and the opening complementary to the bottom wall, the width of which is determined by side webs which is smaller than the distance between the side walls, so that in cross-section the profile groove has a This undercut cavity allows the drive elements to be advantageously moved along the side webs in the corresponding profile groove, which is formed with longitudinal side surfaces. Furthermore, the drive elements are securely held in the profile groove and cannot escape further through the opening.

For this purpose, the guide rail with the opening is mounted and fixed to the window or door on the upper horizontal beam of the frame on the side of the movable sash.

In order to be able to insert the drive elements of the drive device easily and cost-effectively into the profile groove of the guide rail and then securely fix them in a predetermined position, the drive device preferably has at least one positioning device according to the invention, which, like all other drive elements of the drive device, can be displaced upon insertion into the profile groove. Furthermore, the positioning device can be secured against further displacement within the profile groove of the guide rail using simple means. When the positioning device is in the fixed position, which represents the positioned end position for all drive elements of the drive device, the drive elements, when resting against the positioning device, form a connected link. The position can be fixed by the positioning device at both ends of the drive elements. In the present embodiment of the drive device, the positioning device according to the invention is preferably arranged at a second end of the guide rail and thus of the drive elements, wherein the first end of the guide rail and thus also of the drive elements is preferably secured against further displacement by a drive element itself.

The drive elements of the drive device are preferably arranged next to one another in a specific order in the guide rail for automatically moving the movable sash relative to the frame. The positioning device in the guide rail faces at least one free end of the guide rail. All other drive elements are arranged in a row on one side of the positioning device. One of two contact surfaces located in the longitudinal direction of the guide rail and in the longitudinal direction of the positioning device form a flush contact on the side with an end surface of another drive element, in this design variant. All other drive elements are connected in a process of adjacent linking with their respective end surfaces, resulting in a closed and binding structural unit of the drive device. The side of the positioning device forming the contact surface is arranged in a concealed position, facing away from the laterally open ends of the guide rail.

Structurally simple and cost-effective, the positioning device consists of at least one clamping element, whereby it has proven advantageous to arrange two or more clamping elements next to one another for securing it in the guide rail. The clamping elements, like all other drive elements, are inserted into the guide rail from the side of the opening through a recess in the provided profile groove and are then moved towards an end position in a hollow space, engaging behind them and secured against falling out. Two similarly shaped clamping elements are used for this purpose. When the clamping elements are in the fixed end position in the guide rail, the clamping elements rest against one another with contact surfaces, thus increasing the resistance to unintentional displacement of the drive elements in the longitudinal direction of the guide rail.

Both for a guiding position during a longitudinal displacement of the clamping elements within a hollow space of the profile groove of the guide rail, as well as for a positioned fixing of the clamping pieces in the profile groove, the clamping elements have corresponding side surfaces which are guided on side webs of the profile groove within the hollow space of the guide rail and are positioned by clamping pressed against each other to assume an immovable end position in the guide rail.

The positioning device according to the invention proves to be cost-effective because the clamping elements are designed in the same way and can be locked in the same functional manner.

When designing the positioning device, it is necessary to provide not only a housing for the clamping element to guide the guide, but also a cost-effective and easy-to-use fastening means for clamping and locking the clamping element in the profile groove of the guide rail. For this purpose, the clamping element has a threaded pin with a tool engagement, which can be screwed into the housing using a turning tool and, when tightened, presses one end against the bottom wall of the profile groove. The other, free end of the threaded pin has the tool engagement, which is visibly positioned facing the opening of the guide rail for easy handling.

To ensure safe guidance and secure hold of the clamping elements in the guide rail, the clamping elements with the housing are T-shaped in cross-section and adapted to the shape of the cross-section of the profile groove, consisting of the cavity and the opening.

Advantageously, all of the drive elements arranged in the guide rail are tightened to ensure a firm, seamless fit by an additional fastening process of the clamping elements. The drive elements assigned to the remote first end of the positioning device are fixed on one side by means of the positioning device according to the invention or preferably by means of a drive element. The clamping elements are then shifted in position. For this measure, a chamfer or radius is provided on each side of the clamping elements, transverse to the opening of the guide rail, on the visible side of the opening. When the clamping elements are in abutting position in the profile groove, the chamfers lie against one another to form a V-shaped engagement for the application of a lever tool, preferably a screwdriver, wherein the drive elements are tightened by combined loosening and tightening of the clamping elements.

The clamping elements advantageously consist of a die-cast material produced by injection molding or of a plastic.

The invention further relates to a method for producing a fastening of a drive device with drive elements for a displaceable sash as a sliding sash or displaceable lift-slide sash of a window or a door, with a frame in which the sash is displaceably held, in particular according to a fastening of a drive device within the scope of this description. It is provided that the positioning device according to the invention is formed with two identical clamping elements and, with all components of the drive arrangement being arranged in the profile groove of the guide rail, both clamping elements are pushed towards the components to form a system. The second clamping element pointing towards the first free end of the guide rail is clamped in place by means of a turning tool in a tool engagement, the first clamping element is further clamped in place by means of a turning tool engaging between the clamping elements and, by rotation, the first clamping element is clamped in place by means of the turning tool in a tool engagement, the second clamping element is released again and moved towards the adjacent position towards the first clamping element, and, when the turning tool is actuated, exerts a clamped position which further secures the drive device in the guide rail against accidental displacement. The assembly process for fixing and tightening the drive elements of the drive device in the guide rail has a beneficial effect on the travel path of the movable sash relative to the frame. Furthermore, using simple means, it is possible to achieve a virtually resistance-free and noiseless movement of the sash 2 relative to the frame.

The advantages of this type of configuration of the drive device with the positioning device, or rather of this type of procedure, have already been pointed out. Reference is made to both the positioning device and the method for securing the drive elements of the drive device by the positioning device, which can be further developed as described in this description. Likewise, disassembly of the drive device is easily possible in the reverse order, starting with loosening the positioning device and further disassembling the drive elements. Furthermore, it is not necessary to separate the movable sash from the frame when replacing or disassembling the drive device.

The 1 shows a perspective view of a window or door 3, a frame 4 with a movable sash 2 and a fixed sash or door panel 60 adjacent thereto. To operate the movable sash 2, an operating element 61 with a switch is provided on a vertical beam 62, which controls a drive device 1. By operating the operating element 61, the movable sash 2 can be moved, for example, from the position shown in 1 The sliding sash 2 can be moved from its closed position to a position not shown in the direction of the arrow relative to the fixed frame 4 and the fixed sash or door panel 60, but can also be moved to a secured, displaced ventilation position or to a passage opening area. The sliding sash 2 is thereby connected to one or more hanging or 1 supported on a guide rail 64 on the floor side and held movable on the frame 4.

Operation of the drive device 1 via a remote control unit or a smart home system is also conceivable. A radio system is provided in the wall for this purpose, with the control units distributed across the drive components in the sliding sash 2. Likewise, a remote control can be installed on the window or door 3. 1 A power source 24 and, if necessary, a control unit 21 may be provided. The power source 24 and the control unit 21 can also be housed in a wall of a building 23 and are connected to the operating element 61 and the drive device 1 via control and/or power lines 22.

The operating element 61 can also control a drive 66, schematically shown at the front of the vertical beam 62 in the closing direction, which also transfers locking means (not shown) on the vertical beam 62 into a locked closed position or into an unlocked open position of the movable leaf 2. Manual actuation by means of an actuating handle with transmission of an actuating rod to the locking means is also conceivable.

In a system of a sliding lift-sliding sash 2 of a window or a door 3, the movable sash 2 can be moved automatically by the schematically illustrated drive 66 via the operating element 61 or via the manual operating handle from the position shown in the 1 closed position by a coupled pelte connection of the actuating rod to the carriages 65 into a raised opening position in order to be able to be subsequently moved by the drive device 1.

Likewise, both of the above-described actuation variants can be arranged in a window or door 3, which can be selected according to requirements and resemble the character of a hybrid system. Additional drives selected for the system are also connected to the control and/or power lines 22 and linked to the power source 24 and the control unit 21.

In order to enable these positions of the movable sash 2 relative to the fixed frame 4 as well as to the fixed sash or the fixed door panel 60, a special fitting arrangement is provided between the movable sash 2 and the fixed frame 4, namely a so-called system for sliding sashes or sliding lift-slide sashes, of which 1 For the sake of simplicity, only the operating element 61 on the movable wing 2, a part of a lower guide rail 64 arranged on the lower horizontal beam 69 for the carriages 65 and an upper guide rail 5 can be seen.

After 3 The drive device 1 comprises a drive 12 with a threaded spindle 13 driven thereon. The threaded spindle 13 is 4 by a rack element 26 arranged on the frame 4, consisting of individual toothed segments 11. After 1 The drive mechanism 1 is arranged in the installed position of the movable sash 2 almost completely concealed in a recess or receiving groove 27 of an upper horizontal beam 67 of the movable sash 2 and a guide rail 5 arranged on the upper horizontal beam 19 of the frame 4. The drive 12 and the threaded spindle 13 are arranged according to 3 as a structural unit in a housing 28. The toothed segments 11 of the rack element 26 are 7 are almost completely encompassed by a so-called profile groove 7 of the guide rail 5 and rest in the profile groove 7 with side surfaces 9, 9' on side webs 10, 10', secured against falling out. A gap in the guide rail 5 forms in the installed position of the guide rail 5 on the frame 4 according to 5 and 7 an opening 6 pointing in the direction of the sliding sash 2 and thus the possibility of coupling between the components arranged on the movable sash 2 and the components of the drive device 1 mounted on the frame 4. The drive 12 with the threaded spindle 13 is 1 and 4 coupled in the longitudinal direction to the direction of displacement of the movable wing 2 for a rotational transmission of the movement by a tooth transmission.

The movable sliding wing 2 comprises 1 four beams, which are designed as hollow profiles, in particular as aluminum or plastic profiles or as solid profiles made of wood. The beams, such as the beams 62, 63, 67 and 68 described according to 1 , contain prefabricated recesses or grooves for the concealed installation of fitting components. Thus, in the upper horizontal beam 67 in the groove 27 1 the drive device 1 is provided, which is arranged facing the vertical spar 68. The wing-side components of the drive device 1, in particular the housing 28 of the drive 12, are 7 in height H and width B of the recess or receiving groove 27 according to 1 of the upper horizontal spar 67 of the movable wing 2.

To simplify assembly, all components of the drive device 1 are mounted in the housing 28 and in the guide rail 5 before installation. The drive device 1 continues after 5 from a rack element 26, which is composed of several toothed segments 11, further from a toothed segment 11 drivingly connected to a drive 12, a filler piece 25, a charging contact 14 and a positioning device 15 according to the invention. All drive elements 11, 14, 15, 25 are, in the joined and shifted into position, guided into the profile groove 7 of the guide rail 5 according to 9 by the positioning device 15 according to the invention, at least in a displaceable longitudinal direction of the profile groove 7, securing it against further displacement. Thus, all components of the drive device 1 are precisely adjusted in position to the window or door 3. For this purpose, the profile groove 7 has a cross-section 7 and 8 a bottom wall 17, two side walls 18, 18' and the opening 6 opposite the bottom wall 17, the width of which is determined by side webs 10, 10', which is smaller than the distance between the side walls 18, 18', so that in cross section the profile groove 7 forms an undercut cavity 20. In the joined state of the drive elements 11, 14, 15, 25 of the cavity 20 according to 9 , the drive elements 11, 14, 15, 25 are formed with longitudinal side surfaces 9, 9' and are moved in the longitudinal direction of the guide rail 5 on the side webs 10, 10' of the profile groove 7 to the desired position. In the joined position of the drive elements 11, 14, 15, 25 in the profile groove 7, the drive elements 11, 14, 15, 25 find a secure hold and can no longer escape through the opening 6. For a functional drive device 1, the guide rail 5 is 2 and 9 with the opening 6 in mounted and fixed position on the window or door 3 on the upper horizontal beam 19 of the frame 4 on the side of the movable sash 2.

In the fixed position of the positioning device 15 according to the invention, which represents the positioned end position for all drive elements 11, 14, 25 of the drive device 1, the drive elements 11, 14, 25 form a continuous contact with the positioning device 15 according to 2 and 9 an adjacent chain connection. According to an embodiment not shown, positioning of the positioning device 15 at both ends 29, 30 of the guide rail 5 on the drive elements 11, 14, 15 is possible. In the present embodiment, however, a positioning device is omitted, so that the positioning device 15 according to the invention of the drive device 1 is arranged at a second end 30 of the guide rail 5 and on one side 31 of the drive elements 11, 14, 15, wherein the drive elements 11, 14, 15 pointing towards the first end 29 of the guide rail 5 are prevented from further displacement by a drive element itself.

For a functional interaction of the drive elements 11, 14, 25, 15, in particular the functionality of the drive device 1 for automatically moving the movable sash 2 to the frame 4, the drive elements 11, 14, 25, 15 are arranged in a specific order according to 2 and 9 arranged in the guide rail 5. The positioning device 15 faces the second end 30 of the guide rail 5. When the positioning device 15 is secured against further displacement, all further drive elements 11, 14, 25 lean against a flat side 31 of the positioning device 15 in a row. The rack element 26 with the respective toothed segments 11 forms the beginning. Corresponding filler pieces 25 follow the toothed segments 11. Furthermore, a charging contact 14 coming into contact with the filler piece 25 completes the arrangement of the drive device 1 in the guide rail 5 and simultaneously forms the final end of an integral structural unit of the drive device 1 in the guide rail 5. For this purpose, at least one of two longitudinally arranged contact surfaces 35, 36 of the positioning device 15 on side 31 faces an end surface of a further drive element 11 and mutually form a contact surface. All other drive elements 11, 14, 25 follow the process with their respective end faces as mentioned above, so that after 2 and 9 a closed and binding structural unit of the drive device 1. The side 31 of the positioning device 15 forming the contact surfaces 35 is 9 facing away from the second end 30 of the guide rail 5 and thus positioned in a concealed manner.

After 3 and 5 The positioning device 15 has one or more clamping elements 32, 32' for displacement in the profile groove 7 of the guide rail 5 with subsequent locking for an end position. A secure hold is ensured by two similarly shaped clamping elements 32, 32' according to 3 and 4 In the fixed end position of the clamping elements 32, 32' in the guide rail 5 according 9 the clamping elements 32, 32' lie against each other with contact surfaces 35, 36 facing 4 so that the resistance against unintentional displacement of the drive elements 11, 14, 25 in the longitudinal direction of the guide rail 5 increases.

With formed side surfaces 9, 9', the clamping pieces 32, 32' are guided displaceably within the cavity 20 on side webs 10, 10' of the profile groove 7, as well as all other drive elements 11, 14, 25, until the drive elements 11, 14, 15, 25 1 and 2 have taken up their position in the guide rail 5 for operation of the drive device 1. By taking up the position according 9 the clamping elements 32, 32' are rotated by means of a turning tool 40 10 by mutual clamping of the side surfaces 9, 9' on the side webs 10, 10' they are fixed against further displacement and thus assume an immobile position.

The clamping elements 32, 32' are designed for easy handling according to 4 similarly designed. For fixing according to 10 The turning tool 40 is used. The same design also simplifies the assembly of the clamping elements 32, 32' by inserting and moving them. The symmetrical design of the clamping elements 32, 32' according to 4 further simplifies insertion into the profile groove 7. Regardless of the shape of the clamping elements 32, 32', the contact surface 35, 36 is mounted on the left or right side in the longitudinal direction in the profile groove 7 of the guide rail 5.

For fastening the positioning device 15 having clamping elements 32, 32', a fastening means is arranged on the housing 39 of the clamping element 32, 32' forming the guide, which clamps and locks the clamping element 32, 32' in the profile groove 7 of the guide rail 5. For this purpose, the clamping element 32, 32' has 4 a threaded pin 33 with a tool engagement 34, which is in the housing 39 by means of a turning tool 40 10 can be screwed in and when tightened, one end 41 is pressed against the bottom wall 17 of the profile groove 7 7 and 8 The free other end 42 of the threaded pin 33 points 4 the tool intervention 34, which after 10 is visibly arranged pointing towards the opening 6 of the guide rail 5.

In addition, the clamping elements 32, 32' correspond to 7 and the further drive elements 11, 14, 25 in cross section with its housing 39, the T-shaped shape of the profile groove 7 formed in the cross section of the guide rail 5, which is composed of the cavity 20 and the opening 6.

By fixing the positioning device 15 according to the invention by rotatably tightening with clamping of the clamping elements 32, 32' vertically to the longitudinal direction of the guide rail 5, all drive elements 11, 14, 25 located in the guide rail 5 receive by an additional fastening process of the clamping elements 32, 32' according to 10 a firm, seamless fit to each other. The drive elements 11, 14, 25 assigned to the remote first end 29 of the positioning device 15 are moved by means of the positioning device 15 or preferably by means of a drive element 14 facing the end 29 9 fixed on one side. The fixing of the drive element 14 is not further described or shown in the figures. A form-fitting and/or force-fitting fastening method is possible. The clamping elements 32, 32' are then shifted in their position until all drive elements 11, 14, 25, including the positioning device 15, are lined up in the guide rail 5 and rest against the charging contact 14 on one side. In the fixed position of the drive elements 14, 25, 11 in the guide rail 5, the clamping elements 32, 32' are actuated according to a further fastening method, resulting in a play-free and immovable linking of all drive elements 14, 15, 25, 15 in both directions of the guide rail 5. For this measure, 10 A chamfer 37, 38 or a radius is provided on each contact surface 35, 36 of the clamping elements 32, 32', transverse to the opening 6 of the guide rail 5 on the visible side of the opening 6. When the clamping elements 32, 32' are in abutting position in the profile groove 7, the chamfers 37, 38, lying against one another, form a V-shaped engagement 43 for the application of a lever tool, preferably a screwdriver 44, whereby the combined loosening and tightening of the clamping elements 32, 32' causes the drive elements 11, 14, 25, 15 to be tightened.

The 10a until 10d show a schematic representation of assembly steps for tightening and securing the positioning device 15 according to the invention and thus all components of the drive device 1 for a displaceable sash 2 as a sliding sash or displaceable lift-and-slide sash of a window or door 3, with a frame 4 in which the sash 2 is displaceably held. Of the four representations 10a, 10b, 10c, and 10d, the first representation 10a illustrates a first assembly step, the second representation 10b a second assembly step, the third representation 10c a third assembly step, and a fourth representation 10d a fourth assembly step. The first illustration 10a shows the positioning device 15 according to the invention, consisting of two identical clamping elements 32, 32' in abutting arrangement of all components of the drive assembly 1 in the profile groove 7 of the guide rail 5. In the first assembly step, the second clamping element 32' pointing towards the second free end 30 of the guide rail 5 is clamped in a tool engagement 34 by means of a turning tool 40. The second assembly step is shown in illustration 10b, wherein a turning tool 44 engages between the clamping elements 32, 32' in a V-shaped engagement 43 and is intended to cause rotation of the first clamping element 32. In illustration 10c, the turning tool 44 is rotated in the engagement 43 between the clamping elements 32, 32' and generates a contact pressure on the movable clamping element 32 and the other attached drive elements 11, 14, 25. After adjusting the clamping element 32 and forming a gap between the clamping elements 32, 32', the movable and attached clamping element 32 is now clamped in place via the turning tool 40 in a tool engagement 34. The fourth and final illustration 10d refers to the last step for the final and secure fixing of all drive elements 11, 14, 15, 25 of the drive device 1 in the guide rail 5, wherein the second clamping element 32' is again released and displaced toward the adjacent position relative to the first clamping element 32 and, upon actuation of the turning tool 40, is clamped in place, providing further security against unintentional displacement of the drive device 1 in the guide rail 5.

Overall, the described positioning device 15 enables reliable and adjustable fastening of the drive device 1 in the guide rail 5 on the frame 4. Furthermore, a high level of comfort for the window or door 3 is ensured, in particular because undesirable noise generation is prevented. The simple and reproducible manufacture of the positioning device 15 also ensures rapid installation in the guide rail 5 without having to first adjust the position of the threaded pin 33 in the housing 39 of the clamping element 32, 32'.
