Definitions
- the invention relates to a roof sliding window with a plurality of window sashes detachably coupled together, with a motorized reduction drive displaced and in the decoupled state one above the other in a stacking box retractable.
- the first sash is decoupled from the second sash and sunk into the stacker so that the second sash slides over the first sash into the stacker box can be. Accordingly, the remaining window sashes remaining in the window opening are moved.
- the reduction drive by means of which even heavy window sash can be moved, however, means that, for example, in the event of a power failure, the sashes can not be displaced, or only extremely difficult, for closing or releasing the window opening.
- the reduction drive generates by its reduction a high, difficult to not surmountable counter-torque.
- an emergency for example, when it starts to rain and the roof sliding window is open, or when a fire breaks out and the closed roof sliding window closes the only possible exit, it is desirable to be able to manually move the sashes in a simple manner to release the window opening or to close.
- the invention is therefore an object of the invention to provide a roof sliding window that allows manual movement of the casement in an emergency, for example, due to a power failure without particularly high effort.
- the object underlying the invention is achieved in that an actuatable by means of a manually operated adjusting coupling between reduction drive and the / the sash (s) is provided.
- a manually operated adjustment which is manually operated by a user, so in a simple manner by hand.
- the adjusting device acts on a coupling in such a way that it controls the coupling between the reduction drive and the window wing (s). actuated.
- By operating the clutch it can be closed (coupled) or opened (decoupled). This means that by operating the clutch, the operative connection between the reduction drive and the / the window sash (s) can be interrupted.
- the adjusting device by means of which the clutch can be actuated, has an eccentric unit operatively connected to the clutch.
- the eccentric unit is generally understood to mean a device in which a rotational movement due to an eccentricity causes a translational movement.
- the clutch can be closed by simple manual operation without much effort even with high required coupling forces in a simple way or open or clutch or decouple.
- the adjusting device has at least one displaceable by the eccentric unit, the clutch actuated actuating rod.
- the rotational movement of the eccentric unit is thus transmitted via the actuating rod to the coupling.
- the actuating rod is positively connected to the eccentric unit.
- the eccentric unit has a circular eccentric disc, on which a driving means, such as a pin, is arranged eccentrically, which engages in an end-side receptacle of the actuating rod. Due to the eccentric arrangement of the pin on the circular eccentric disc, the connecting rod undergoes a translational movement.
- the circular eccentric disc of the eccentric unit is mounted eccentrically rotatable. This results in that the lateral surface of the circular eccentric disc not only rotates during rotation, but also in a plane perpendicular to the axis of rotation (translational) is displaced.
- the actuating rod has at its end associated with the eccentric on a circular bearing ring, in which engages the circular eccentric disc.
- the eccentric disc is expediently substantially form-fitting in the circular bearing ring, so that although the sideways movement of the eccentric disc, but not the rotational movement is transmitted to the bearing ring.
- a sliding bearing is suitably designed so that the lowest possible friction losses.
- the eccentric disk has a shoulder projecting beyond the bearing ring on one end face, which serves both for axial bearing of the bearing ring and for protection of the sliding bearing against contamination.
- the bearing ring is either moored as a separate component on the actuating rod or formed integrally therewith. In a separate Training the bearing ring, the actuating rod is advantageously secured by means of screwing and / or bonding to this, so that a power and motion transmission is permanently guaranteed.
- the adjusting device and / or the clutch at least one return spring, which biases the clutch in its coupled state.
- the return spring thus urging the clutch always in its coupled / closed state, so that unintentional opening or decoupling is prevented.
- the return spring may be part of the adjustment and / or the clutch itself. It is essential that they apply the clutch directly or indirectly, preferably pressurized.
- the return spring can be designed as a helical spring, spiral spring, coil spring, disc spring, disc spring or the like. Depending on where the return spring is to act on the clutch, it may be useful to provide several return springs, so that the force is evenly distributed to the clutch.
- the adjusting device and / or the eccentric unit are designed to be self-locking at least in the uncoupled state.
- This can be realized by choosing appropriate dimensions and / or friction, in particular between the eccentric and the bearing ring.
- the coupling is designed as a positive coupling, in particular as a tooth or dog clutch.
- the toothed coupling advantageously has an axially displaceable coupling sleeve, which is provided with at least one internal toothing, which can be brought into engagement with an external toothing of at least one toothed wheel by axial displacement for coupling.
- the coupling sleeve has a first internal toothing, which is always in engagement with a reduction gear belonging to the outer toothing of a first gear, and a second internal toothing, which can be brought by axial displacement with the outer toothing of the power transmission to the window sash second gear engaged or operatively engageable is.
- the coupling sleeve can of course always be in engagement with the second gear and be brought into or out of engagement by displacement with the first gear.
- the coupling sleeve has a single internal toothing, which extends over the entire length of the coupling sleeve, so that the first internal toothing merges into the second.
- at least one of the external gears or one of the gear wheels is crowned in order to be able to compensate for a manufacturing tolerance-related shaft misalignment.
- the coupling sleeve of the toothed coupling by means of the actuating rod is axially displaceable.
- the actuating rod is pivotally operatively connected to the coupling sleeve, so that the displacement of the bearing ring by the eccentric disc does not lead to a bending stress of the actuating rod.
- the operating rod must not be connected directly to the coupling sleeve, since the latter must be able to rotate.
- the actuating rod is therefore connected to at least one coupling sleeve at least axially supporting element.
- the coupling sleeve is rotatably held between two displaceable by the actuating rod coupling plates.
- the actuating rod thus cooperates with two displaceable coupling plates, between which the coupling sleeve is rotatably held.
- the coupling plates thus serve as the coupling sleeve axially and preferably also radially supporting elements.
- the adjusting device and / or the toothed coupling to an elastically deformable force-transmitting element which is an adjustment of the eccentric for engaging the internal teeth of the coupling sleeve with the second gear at any time, especially if the coupling sleeve is not on the second gear is pushed, allowed.
- the coupling sleeve can be brought into engagement with the toothed wheel only if the teeth of the internal toothing can engage in the interdental spaces of the second toothed wheel.
- a synchronization of the coupling sleeve with the gear to be engaged is necessary, otherwise the teeth of the internal teeth abut against the teeth of the gear end face and thus preventing a coupling.
- the advantageous elastically deformable force transmission element serves to ensure that the movement generated by the eccentric unit is not transmitted to the clutch via a rigid connection. Rather, the force transmission element converts the movement of the eccentric unit or the adjusting device into a force to be transmitted by being elastically deformable. Deformation allows any movement but does not transmit it directly. Rather, an additional force component is generated.
- the force-transmitting element between the actuating rod and the coupling sleeve is arranged.
- the force-transmitting element is arranged between the actuating rod and the coupling sleeve such that when the actuating rod is displaced by the eccentric unit and the toothed coupling is not synchronized, the force-transmitting member is deformed to accommodate the movement of the actuating rod.
- the coupling sleeve is pushed onto the gear due to the force stored in the elastically deformed force transmitting member and engaged therewith. In this way, it is ensured that the user can always operate the adjusting device and an automatic synchronization of the toothed coupling takes place.
- the force transmission element is designed as a spring element, in particular as a helical spring.
- the window sash each have a toothed rack, which can be brought into engagement with a drivable by the reduction drive via the clutch driving means.
- the clutch or gear coupling is arranged between the reduction drive and the power or movement on the sash transferring driving means.
- the entrainment means is a gear or a toothed gear and / or a chain drive.
- the advantage of the chain drive is that the rack of the corresponding sash can engage the chain over a wide range, so that high forces can be transmitted.
- a releasable by the eccentric signal generator for detecting the state of the adjusting device is provided, wherein preferably an actuating element of the signal generator by the free outer shell surface of the bearing ring and / or eccentric disc can be actuated or acted upon.
- the signal generator can serve, for example, to inform a control device whether the clutch is open or closed.
- the controller can then enable or disable functions of the roof sliding window.
- the control device interrupts the power supply to the reduction drive when detecting the open state of the clutch.
- FIGS. 1 and 2 show in a perspective view or in a perspective exploded view of a drive unit 1 of a roof sliding window 2, not shown here, which has a plurality of window sash, which are releasably coupled together, slidably and in the decoupled state one above the other in a stacking box retractable.

- the reduction drive essentially comprises an electric motor 4 and a reduction gear 5 driven by it.
- the reduction gear 5 is adjoined by a clutch 6. This is in operative connection with the reduction gear 5 or with an output shaft of the reduction gear 5, so that a rotational movement of the output shaft is transmitted to the clutch 6.
- the coupling 6 is operatively connected to a drive shaft 7 of a chain drive 8.
- the chain drive 8, whose chain is not shown here for reasons of clarity, furthermore comprises three deflection rollers 9, 10 and 11 serving to guide the chain.

- the chain of the chain drive 8 here represents a driving means 13, which cooperates with the window sash associated racks for moving the sash.
- the deflection roller 9 is displaceable in its position, as best of the FIG. 2 apparent, so they as Tensioning pulley for tensioning the chain drive.
- the roof sliding window can thus be opened or closed by moving the window sash through the reduction drive 3, via the coupling 6 and the chain drive 8.
- the chain runs around the pulleys 9, 10 and 11 and the chain driving the gear 12, the pulleys 10 and 11 are arranged in a line parallel to the racks of the window sash, so that the racks according to the length of the chain between the Deflection pulleys 10 and 11 are engageable with the chain.
- the clutch 6 On the training and function of the clutch 6 will be discussed later.

- the eccentric 18 engages in a circular bearing ring 20 a. Wherein eccentric and bearing ring 20 advantageously are formed so that only a small clearance between the two is present.
- the bearing ring 20 is thus rotatably mounted on the eccentric disc 18 in a form-fitting manner.
- the eccentric disc 18 further has a shoulder 21, with which it projects beyond the bearing ring 20.
- the shoulder 21 acts as a thrust bearing for the eccentric disk 18 on the bearing ring 20.
- the bearing ring 20 also has a receptacle 22 for the actuating rod 16.
- the receptacle 22 is formed as a threaded bore into which the actuating rod is screwed with a corresponding mating thread.

- a corresponding tool can act on the actuating element 24 or on the external hexagon 25. By rotating or operating the tool, the eccentric disk 18 can be eccentrically displaced / rotated about its axis of rotation 19.
- the bearing ring 20 By rotating the eccentric disk 18, the bearing ring 20 is displaced in its position, so that this substantially translational movement of the bearing ring 20 is transmitted to the actuating rod 16. This in turn transmits the movement to the carriage unit 17, which is operatively connected to the clutch 6 to actuate the latter.
- the clutch 6 By operating the adjusting device 14 by means of the eccentric 15 so here the clutch 6 is operated manually in a simple manner.
- the eccentric 15 acts on the operating rod 16 essentially like an actuation cam.

- the toothed coupling 26 has a second gear 37, which is non-rotatably connected to the drive shaft 7 of the chain drive 8, in this case also by means of a grub screw 38, is connected.
- Both gears 35 and 37 are in the illustrated embodiment in engagement with the internal teeth 28 of the coupling sleeve 27.
- the teeth or external teeth of the gears 35 and 37 are designed crowned, so in particular an angular offset between the output shaft of the reduction drive 3 and the drive shaft 7 of the chain drive 8 can be compensated or compensated.
- the clutch plates 29 and 30 are mounted by means of bearing pin 39 parallel to the axis of rotation of the coupling sleeve 27 slidably.
- the bearing pins 39 are in openings 42 of the coupling plates 29, 30 and have at one end a screw head 40 and at its other end a thread 41.
- the bearing pins 39 are first with their threaded end 41 having through each one of the openings 42 in the clutch plate 29, then by a spacer sleeve 43 which determines the distance between the two clutch plates 29 and 30, then through the corresponding opening 42nd the coupling plate 30 out.
- a further spacer sleeve 44 is pushed onto each of the bearing pin 39, which is supported on the front side of the coupling plate 30.
- the outer diameter of the spacer sleeves 44 is chosen such that it cooperates with holes 45 of a stationary retaining flange 46 as a plain bearing or axial guide.
- the diameter of the nuts 49 and / or the washers 48 is greater than that of the holes 45, they form a stop which limits the displacement of the coupling plates 29, 30 and the coupling sleeve 27.
- the structure of coupling plates 29 and 30 and coupling sleeve 27 is held together in each case by the nut 49, the spacer sleeves 43 and 44 and by the screw head 40.
- four return springs 50 which are designed as helical springs, are furthermore arranged. On the function of the return springs 50 will be discussed later in more detail.
- On the back of the retaining flange 46 of the reduction drive 3 is arranged and screwed to this.
- the holder flange 46 also has an open-edged recess 52, which serves to receive a rod-shaped profile element 53.
- the retaining flange 46 can be fastened or fastened on both sides to groove stones 55 held in lateral longitudinal grooves of the profile element 53.
- the profile element 53 further has on its underside a longitudinal guide 56, which is also formed like a groove and having an undercut, such that the carriage unit 17 is longitudinally displaceable therein is held positively held.
- the carriage unit 17 has two carriages 57, 58, which have an outer profile that is complementary to the longitudinal guide 56.

- the movement is transmitted to the carriage 57. If the clutch 6 is synchronized, so the coupling sleeve 27 can be pushed onto the gear 37, because the teeth of the gear 37 with interdental spaces the coupling sleeve 27 are aligned, the coupling 6 is coupled.
- the clutch 6 is not synchronized, that is to say that the teeth of the gear 37 strike the teeth of the coupling sleeve 27, the movement of the carriage 57 is obstructed and the helical spring 62 is elastically deformed by the further movement of the carriage 58, so that the carriage 58 or eccentric unit 15 can be adjusted without the adjusting device 14 or the clutch 6 are damaged.
- the coupling sleeve 27 or the gear 37 is rotated so that the coupling 6 is synchronized, the energy stored in the helical spring 62 ensures that the slide 57 is displaced counter to the direction of the arrow 67 and thus the coupling sleeve 27 is pushed onto the gear 37 and coupled with it.
- the return springs 50 between the clutch plate 30 and the retaining flange 46 as compression springs ensure that the clutch 6 is always urged into the coupled state, so that an unintentional uncoupling of the drive unit 1 during operation is prevented.
- the clutch 6 By means of the manually operated adjusting device 14, by means of which the clutch 6 can be actuated, it is possible in a simple manner to separate a defect of the reduction drive 3 or, in the event of a power failure, the reduction drive 3 from the window sashes, so that they can easily be displaced by hand in the window opening are. This ensures that even in an emergency, the roof sliding window can be opened or closed by a user in a simple manner.
- the eccentric unit 15 is advantageously assigned a signal generator 68.
- This has an actuating element 69 which has a wheel at its free end, which runs on the outer shell surface of the bearing ring 20.
- the signal generator 68 thus serves to detect the rotational position of the eccentric unit 15 or the state of the adjusting device 14. For example, it can be provided that upon detection of the decoupled state of the adjusting device 14, the power supply to the reduction drive 3 is interrupted.
Abstract
Description
Die Erfindung betrifft ein Dachschiebefenster mit mehreren Fensterflügeln, die miteinander lösbar kuppelbar, mit einem motorischen Untersetzungsantrieb verschiebbar und im entkoppelten Zustand übereinander in einem Stapelkasten einfahrbar sind.The invention relates to a roof sliding window with a plurality of window sashes detachably coupled together, with a motorized reduction drive displaced and in the decoupled state one above the other in a stacking box retractable.
Dachschiebefenster der eingangs genannten Art sind dem Fachmann aus dem Stand der Technik bekannt. Bei derartigen Dachschiebefenstern handelt es sich in der Regel um Wohndachfenster, deren Fensterflügel zum Öffnen oder Verschließen einer Fensteröffnung seitlich verschiebbar sind. Im geschlossenen Zustand des Dachschiebefensters verschließen die Fensterflügel nebeneinander liegend die Fensteröffnung. Der einem neben der Fensteröffnung angeordneten Stapelkasten am nächsten liegende Fensterflügel steht dabei in Wirkverbindung mit einem motorischen Untersetzungsantrieb, der in und/oder an dem Stapelkasten angeordnet sein kann. Wird der Untersetzungsantrieb betätigt, so übt er eine Kraft auf den genannten Fensterflügel aus, um diesen in den Stapelkasten zu verschieben. Da die Fensterflügel im geschlossenen Zustand miteinander gekuppelt sind, überträgt sich die Bewegung des genannten (ersten) Fensterflügels auf die übrigen Fensterflügel. Sobald der folgende (zweite) Fensterflügel mit dem motorischen Untersetzungsantrieb in Wirkkontakt kommt, sodass dieser den Fensterflügel direkt verschieben kann, wird der erste Fensterflügel von dem zweiten Fensterflügel entkoppelt und in dem Stapelkasten versenkt, sodass der zweite Fensterflügel über den ersten Fensterflügel in den Stapelkasten geschoben werden kann. Entsprechend wird mit den übrigen, in der Fensteröffnung verbliebenen Fensterflügeln verfahren. Durch das Übereinanderstapeln der Fensterflügel im entkoppelten Zustand, wird eine besonders platzsparende Möglichkeit zur Aufbewahrung der Fensterflügel geboten, wobei eine große Fensteröffnung verschlossen beziehungsweise freigegeben werden kann. Der Untersetzungsantrieb, mittels dessen sich auch schwere Fensterflügel verschieben lassen, führt jedoch dazu, dass beispielsweise bei einem Stromausfall die Fensterflügel nicht oder nur äußerst schwer zum Verschließen oder Freigeben der Fensteröffnung verschoben werden können. Der Untersetzungsantrieb erzeugt durch seine Untersetzung ein hohes, nur schwer bis nicht überwindbares Gegenmoment. Im Notfall, beispielsweise wenn es anfängt zu regnen und das Dachschiebefenster geöffnet ist, oder wenn ein Feuer ausbricht und das geschlossene Dachschiebefenster den einzig möglichen Ausgang verschließt, ist es wünschenswert, die Fensterflügel manuell auf einfache Art und Weise verschieben zu können, um die Fensteröffnung freizugeben oder zu verschließen.Dachschiebefenster the aforementioned type are known in the art from the prior art. In such roof sliding windows are usually rooftop windows, the sash can be moved laterally to open or close a window opening. When the roof sliding window is closed, the window sashes close the window opening side by side. The window sash next to the window opening arranged stacking box is in operative connection with a motorized reduction drive, which can be arranged in and / or on the stacking box. If the reduction drive is actuated, it exerts a force on said window sash in order to move it into the stacking box. Since the casements are coupled together in the closed state, the movement of said (first) casement is transferred to the remaining casement windows. As soon as the following (second) window sash comes into operative contact with the motorized reduction drive, so that it can move the sash directly, the first sash is decoupled from the second sash and sunk into the stacker so that the second sash slides over the first sash into the stacker box can be. Accordingly, the remaining window sashes remaining in the window opening are moved. By the stacking of the window sash in the decoupled state, a particularly space-saving option for storing the window sash is offered, with a large window opening can be closed or released. However, the reduction drive, by means of which even heavy window sash can be moved, however, means that, for example, in the event of a power failure, the sashes can not be displaced, or only extremely difficult, for closing or releasing the window opening. The reduction drive generates by its reduction a high, difficult to not surmountable counter-torque. In an emergency, for example, when it starts to rain and the roof sliding window is open, or when a fire breaks out and the closed roof sliding window closes the only possible exit, it is desirable to be able to manually move the sashes in a simple manner to release the window opening or to close.
Der Erfindung liegt somit die Aufgabe zugrunde, ein Dachschiebefenster zu schaffen, das ein manuelles Verschieben der Fensterflügel im Notfall, beispielsweise aufgrund eines Stromausfalls, ohne besonders hohen Kraftaufwand ermöglicht.The invention is therefore an object of the invention to provide a roof sliding window that allows manual movement of the casement in an emergency, for example, due to a power failure without particularly high effort.
Die der Erfindung zugrunde liegende Aufgabe wird dadurch gelöst, dass eine mittels einer manuell zu bedienenden Verstelleinrichtung betätigbare Kupplung zwischen Untersetzungsantrieb und dem/den Fensterflügel(n) vorgesehen ist. Es ist also eine manuell zu bedienende Verstelleinrichtung vorgesehen, die von einem Benutzer manuell, also auf einfache Art und Weise per Hand bedienbar ist. Die Verstelleinrichtung wirkt auf eine Kupplung derart, dass sie die Kupplung zwischen Untersetzungsantrieb und dem/den Fensterflügel(n) betätigt. Durch das Betätigen der Kupplung kann diese geschlossen (gekuppelt) oder geöffnet (entkuppelt) werden. Das bedeutet, dass durch das Betätigen der Kupplung die Wirkverbindung zwischen dem Untersetzungsantrieb und dem/den Fensterflügel(n) unterbrochen werden kann. Durch bedienen der Verstelleinrichtung kann somit ein Benutzer leicht die Kupplung und somit die Wirkverbindung zwischen Untersetzungsantrieb und Fensterflügel lösen, sodass sich letzterer leicht in der Fensteröffnung verschieben lässt, da nunmehr das Gegenmoment des Untersetzungsantriebs nicht mehr überwunden werden muss. Im Notfall kann also der Benutzer den/die Fensterflügel durch Betätigen der Kupplung mittels der Verstelleinrichtung von dem Untersetzungsantrieb lösen und sodann frei in der Fensteröffnung verschieben.The object underlying the invention is achieved in that an actuatable by means of a manually operated adjusting coupling between reduction drive and the / the sash (s) is provided. Thus, it is provided a manually operated adjustment, which is manually operated by a user, so in a simple manner by hand. The adjusting device acts on a coupling in such a way that it controls the coupling between the reduction drive and the window wing (s). actuated. By operating the clutch, it can be closed (coupled) or opened (decoupled). This means that by operating the clutch, the operative connection between the reduction drive and the / the window sash (s) can be interrupted. By operating the adjusting device thus a user can easily solve the coupling and thus the operative connection between reduction drive and window sash, so that the latter can be easily moved in the window opening, since now the counter-torque of the reduction drive no longer needs to be overcome. In an emergency, therefore, the user can solve the / the sash by pressing the clutch by means of the adjustment of the reduction drive and then move freely in the window opening.
Vorteilhafterweise weist die Verstelleinrichtung, mittels derer die Kupplung betätigbar ist, eine mit der Kupplung wirkverbundene Exzentereinheit auf. Unter der Exzentereinheit ist hierbei im Allgemeinen eine Einrichtung zu verstehen, bei der eine Drehbewegung aufgrund einer Exzentrizität eine Translationsbewegung bewirkt. Damit lässt sich die Kupplung durch einfache manuelle Betätigung ohne großen Kraftaufwand auch bei hohen erforderlichen Kupplungskräften auf einfache Art und Weise schließen oder öffnen beziehungsweise kuppeln oder entkuppeln.Advantageously, the adjusting device, by means of which the clutch can be actuated, has an eccentric unit operatively connected to the clutch. In this case, the eccentric unit is generally understood to mean a device in which a rotational movement due to an eccentricity causes a translational movement. Thus, the clutch can be closed by simple manual operation without much effort even with high required coupling forces in a simple way or open or clutch or decouple.
Weiterhin ist vorgesehen, dass die Verstelleinrichtung wenigstens eine durch die Exzentereinheit verlagerbare, die Kupplung betätigende Betätigungsstange aufweist. Die Drehbewegung der Exzentereinheit wird somit über die Betätigungsstange auf die Kupplung übertragen. Durch das Vorsehen der Betätigungsstange kann die räumliche Anordnung der Exzentereinheit zu der Kupplung relativ frei gewählt werden, sodass eine bauraumoptimierte Ausbildung der Verstelleinrichtung möglich ist. Vorteilhafterweise ist die Betätigungsstange formschlüssig mit der Exzentereinheit verbunden. Im einfachsten Fall weist die Exzentereinheit eine kreisförmige Exzenterscheibe auf, auf der ein Mitnahmemittel, wie beispielsweise ein Zapfen, exzentrisch angeordnet ist, der in eine endseitige Aufnahme der Betätigungsstange eingreift. Durch die exzentrische Anordnung des Zapfens auf der kreisförmigen Exzenterscheibe erfährt die Pleuelstange eine Translationsbewegung.Furthermore, it is provided that the adjusting device has at least one displaceable by the eccentric unit, the clutch actuated actuating rod. The rotational movement of the eccentric unit is thus transmitted via the actuating rod to the coupling. By providing the actuating rod, the spatial arrangement of the eccentric unit to the clutch relatively free be selected so that a space-optimized design of the adjustment is possible. Advantageously, the actuating rod is positively connected to the eccentric unit. In the simplest case, the eccentric unit has a circular eccentric disc, on which a driving means, such as a pin, is arranged eccentrically, which engages in an end-side receptacle of the actuating rod. Due to the eccentric arrangement of the pin on the circular eccentric disc, the connecting rod undergoes a translational movement.
Bevorzugt ist die kreisförmige Exzenterscheibe der Exzentereinheit jedoch exzentrisch verdrehbar gelagert. Das führt dazu, dass die Mantelfläche der kreisförmigen Exzenterscheibe beim Verdrehen nicht nur rotiert, sondern auch in einer Ebene senkrecht zur Drehachse (translatorisch) verlagert wird.Preferably, however, the circular eccentric disc of the eccentric unit is mounted eccentrically rotatable. This results in that the lateral surface of the circular eccentric disc not only rotates during rotation, but also in a plane perpendicular to the axis of rotation (translational) is displaced.
Vorteilhafterweise weist die Betätigungsstange an ihrem der Exzentereinheit zugeordneten Ende einen kreisförmigen Lagerring auf, in welchen die kreisförmige Exzenterscheibe eingreift. Die Exzenterscheibe liegt zweckmäßigerweise im Wesentlichen formschlüssig in dem kreisförmigen Lagerring ein, sodass zwar die Seitwärtsbewegung der Exzenterscheibe, nicht jedoch die Drehbewegung auf den Lagerring übertragen wird. Zwischen Lagerring und Exzenterscheibe ist zweckmäßigerweise ein Gleitlager ausgebildet, sodass möglichst geringe Reibverluste entstehen. Vorteilhafterweise weist die Exzenterscheibe eine den Lagerring an einer Stirnseite überragenden Schulter auf, die sowohl zur Axiallagerung des Lagerrings als auch zum Schutz des Gleitlagers vor Verschmutzung dient. Der Lagerring ist dabei entweder als separates Bauteil an der Betätigungsstange festgemacht oder einstückig mit dieser ausgebildet. Bei einer separaten Ausbildung des Lagerrings ist die Betätigungsstange vorteilhafterweise mittels Verschraubung und/oder Verklebung an diesem befestigt, sodass eine Kraft- und Bewegungsübertragung dauerhaft gewährleistet ist.Advantageously, the actuating rod has at its end associated with the eccentric on a circular bearing ring, in which engages the circular eccentric disc. The eccentric disc is expediently substantially form-fitting in the circular bearing ring, so that although the sideways movement of the eccentric disc, but not the rotational movement is transmitted to the bearing ring. Between bearing ring and eccentric a sliding bearing is suitably designed so that the lowest possible friction losses. Advantageously, the eccentric disk has a shoulder projecting beyond the bearing ring on one end face, which serves both for axial bearing of the bearing ring and for protection of the sliding bearing against contamination. The bearing ring is either moored as a separate component on the actuating rod or formed integrally therewith. In a separate Training the bearing ring, the actuating rod is advantageously secured by means of screwing and / or bonding to this, so that a power and motion transmission is permanently guaranteed.
Nach einer Weiterbildung der Erfindung weisen die Verstelleinrichtung und/oder die Kupplung mindestens eine Rückstellfeder auf, die die Kupplung in ihrem gekuppelten Zustand vorspannt. Die Rückstellfeder drängt also die Kupplung stets in ihren gekuppelten/geschlossenen Zustand, sodass ein ungewolltes Öffnen beziehungsweise Entkuppeln verhindert wird. Die Rückstellfeder kann dabei Bestandteil der Verstelleinrichtung und/oder der Kupplung selbst sein. Wesentlich dabei ist, dass sie die Kupplung direkt oder indirekt, vorzugsweise druck-beaufschlagt. Die Rückstellfeder kann dabei als Schraubenfeder, Biegefeder, Spiralfeder, Scheibenfeder, Tellerfeder oder Ähnliches ausgebildet sein. Je nach dem, an welcher Stelle die Rückstellfeder die Kupplung beaufschlagen soll, kann es sinnvoll sein, mehrere Rückstellfedern vorzusehen, sodass die Kraft gleichmäßig auf die Kupplung verteilt wird.According to a development of the invention, the adjusting device and / or the clutch at least one return spring, which biases the clutch in its coupled state. The return spring thus urging the clutch always in its coupled / closed state, so that unintentional opening or decoupling is prevented. The return spring may be part of the adjustment and / or the clutch itself. It is essential that they apply the clutch directly or indirectly, preferably pressurized. The return spring can be designed as a helical spring, spiral spring, coil spring, disc spring, disc spring or the like. Depending on where the return spring is to act on the clutch, it may be useful to provide several return springs, so that the force is evenly distributed to the clutch.
Vorteilhafterweise sind die Verstelleinrichtung und/oder die Exzentereinheit zumindest im entkuppelten Zustand selbsthemmend ausgebildet. Dies kann durch die Wahl entsprechender Dimensionen und/oder Reibwirkungen, insbesondere zwischen der Exzenterscheibe und dem Lagerring realisiert werden. Selbsthemmung hat zur Folge, dass sich die Verstelleinrichtung im entkuppelten Zustand nicht von selbst, insbesondere nicht aufgrund der oben beschriebenen Rückstellfedern verstellen kann, was zu einem ungewollten Schließen der Kupplung führen würde. Durch die vorteilhafte Selbsthemmung wird gewährleistet, dass der Benutzer nach Bedienen der Verstelleinrichtung sich ganz auf die Fensterflügel konzentrieren kann und insbesondere die Verstelleinrichtung nicht in ihrer Entkupplungseinstellung halten muss, während er den oder die Fensterflügel verschiebt.Advantageously, the adjusting device and / or the eccentric unit are designed to be self-locking at least in the uncoupled state. This can be realized by choosing appropriate dimensions and / or friction, in particular between the eccentric and the bearing ring. Self-locking has the consequence that the adjusting device in the uncoupled state can not adjust by itself, in particular not due to the above-described return springs, which would lead to an unwanted closing of the clutch. Due to the advantageous self-locking ensures that the user after operating the Adjustment can concentrate entirely on the casement and in particular must not hold the adjustment in their Entkupplungseinstellung while he moves the or the casement.
Ferner ist vorgesehen, dass die Kupplung als formschlüssige Kupplung, insbesondere als Zahn- oder Klauenkupplung ausgebildet ist. Die Zahnkupplung weist vorteilhafterweise eine axial verschiebbare Kupplungshülse auf, die mit zumindest einer Innenverzahnung versehen ist, welche mit einer Außenverzahnung zumindest eines Zahnrads durch axiales Verschieben zum Kuppeln in Eingriff bringbar ist. Bevorzugt weist die Kupplungshülse eine erste Innenverzahnung auf, die stets mit einer dem Untersetzungsantrieb zugehörigen Außenverzahnung eines ersten Zahnrads in Eingriff steht, sowie eine zweite Innenverzahnung, die durch axiales Verschieben mit der Außenverzahnung eines der Kraftübertragung auf die Fensterflügel dienenden zweiten Zahnrads in Eingriff bringbar beziehungsweise wirkverbindbar ist. Alternativ kann die Kupplungshülse natürlich auch stets mit dem zweiten Zahnrad in Eingriff stehen und durch Verschieben mit dem ersten Zahnrad in oder außer Eingriff bringbar sein. Bevorzugt weist die Kupplungshülse eine einzige Innenverzahnung auf, die sich über die gesamte Länge der Kupplungshülse erstreckt, sodass die erste Innenverzahnung in die zweite übergeht. Vorteilhafterweise ist zumindest eine der Außenverzahnungen beziehungsweise eines der Zahnräder ballig ausgebildet, um einen fertigungstoleranzbedingten Wellenversatz ausgleichen zu können.It is further provided that the coupling is designed as a positive coupling, in particular as a tooth or dog clutch. The toothed coupling advantageously has an axially displaceable coupling sleeve, which is provided with at least one internal toothing, which can be brought into engagement with an external toothing of at least one toothed wheel by axial displacement for coupling. Preferably, the coupling sleeve has a first internal toothing, which is always in engagement with a reduction gear belonging to the outer toothing of a first gear, and a second internal toothing, which can be brought by axial displacement with the outer toothing of the power transmission to the window sash second gear engaged or operatively engageable is. Alternatively, the coupling sleeve can of course always be in engagement with the second gear and be brought into or out of engagement by displacement with the first gear. Preferably, the coupling sleeve has a single internal toothing, which extends over the entire length of the coupling sleeve, so that the first internal toothing merges into the second. Advantageously, at least one of the external gears or one of the gear wheels is crowned in order to be able to compensate for a manufacturing tolerance-related shaft misalignment.
Zweckmäßigerweise ist die Kupplungshülse der Zahnkupplung mittels der Betätigungsstange axial verschiebbar. Vorteilhafterweise ist dabei die Betätigungsstange gelenkig mit der Kupplungshülse wirkverbunden, sodass die Verlagerung des Lagerrings durch die Exzenterscheibe nicht zu einer Biegebeanspruchung der Betätigungsstange führt. Natürlich darf die Betätigungsstange nicht direkt mit der Kupplungshülse verbunden sein, da Letztere rotieren können muss. Zweckmäßigerweise ist die Betätigungsstange daher mit mindestens einem die Kupplungshülse zumindest axial lagernden Element verbunden.Conveniently, the coupling sleeve of the toothed coupling by means of the actuating rod is axially displaceable. Advantageously, while the actuating rod is pivotally operatively connected to the coupling sleeve, so that the displacement of the bearing ring by the eccentric disc does not lead to a bending stress of the actuating rod. Of course, the operating rod must not be connected directly to the coupling sleeve, since the latter must be able to rotate. Conveniently, the actuating rod is therefore connected to at least one coupling sleeve at least axially supporting element.
Weiterhin ist vorgesehen, dass die Kupplungshülse zwischen zwei durch die Betätigungsstange verschiebbare Kupplungsplatten verdrehbar gehalten ist. Die Betätigungsstange wirkt also mit zwei verschiebbaren Kupplungsplatten zusammen, zwischen denen die Kupplungshülse verdrehbar gehalten ist. Die Kupplungsplatten dienen also als die Kupplungshülse axial und bevorzugt auch radial lagernde Elemente. Durch Verschieben der Kupplungsplatten kann dadurch auf einfach Art und Weise die Kupplungshülse zum Kuppeln oder Entkuppeln verschoben werden.It is further provided that the coupling sleeve is rotatably held between two displaceable by the actuating rod coupling plates. The actuating rod thus cooperates with two displaceable coupling plates, between which the coupling sleeve is rotatably held. The coupling plates thus serve as the coupling sleeve axially and preferably also radially supporting elements. By moving the clutch plates can thus be easily moved the coupling sleeve for coupling or decoupling in a simple manner.
Nach einer vorteilhaften Weiterbildung der Erfindung weisen die Verstelleinrichtung und/oder die Zahnkupplung ein elastisch verformbares Kraft-Übertragungselement auf, das ein Verstellen der Exzentereinheit zum In-Eingriff-Bringen der Innenverzahnung der Kupplungshülse mit dem zweiten Zahnrad jederzeit, insbesondere wenn die Kupplungshülse nicht auf das zweite Zahnrad aufschiebbar ist, erlaubt. Die Kupplungshülse kann nur dann mit dem Zahnrad in Eingriff gebracht werden, wenn die Zähne der Innenverzahnung in die Zahnzwischenräume des zweiten Zahnrads eingreifen können. Somit ist eine Synchronisation der Kupplungshülse mit dem in Eingriff zu bringenden Zahnrad notwendig, da sonst die Zähne der Innenverzahnung gegen die Zähne des Zahnrads stirnseitig stoßen und somit ein Kuppeln verhindern würden. Das vorteilhafte elastisch verformbare Kraft-Übertragungselement dient dazu, dass die durch die Exzentereinheit erzeugte Bewegung nicht über eine starre Verbindung auf die Kupplung übertragen wird. Vielmehr wandelt das Kraft-Übertragungselement die Bewegung der Exzentereinheit beziehungsweise der Verstelleinrichtung in eine zu übertragende Kraft um, indem es sich elastisch verformen lässt. Durch das Verformen wird jede Bewegung erlaubt, jedoch nicht direkt übertragen. Vielmehr wird eine zusätzliche Kraftkomponente erzeugt. Vorteilhafterweise ist das Kraft-Übertragungselement zwischen der Betätigungsstange und der Kupplungshülse angeordnet. Vorteilhafterweise ist das Kraft-Übertragungselement zwischen der Betätigungsstange und der Kupplungshülse derart angeordnet, dass, wenn die Betätigungsstange durch die Exzentereinheit verlagert wird, und die Zahnkupplung nicht synchronisiert ist, das Kraft-Übertragungselement verformt wird, um die Bewegung der Betätigungsstange aufzunehmen. Sobald die Zahnkupplung jedoch synchronisiert ist, wird die Kupplungshülse aufgrund der in dem elastisch verformten Kraft-Übertragungselement gespeicherten Kraft auf das Zahnrad geschoben und mit diesem in Eingriff gebracht. Auf diese Art und Weise wird gewährleistet, dass der Benutzer die Verstelleinrichtung stets betätigen kann und eine automatische Synchronisation der Zahnkupplung erfolgt. Vorteilhafterweise ist das Kraft-Übertragungselement als Federelement, insbesondere als Schraubenfeder, ausgebildet.According to an advantageous embodiment of the invention, the adjusting device and / or the toothed coupling to an elastically deformable force-transmitting element, which is an adjustment of the eccentric for engaging the internal teeth of the coupling sleeve with the second gear at any time, especially if the coupling sleeve is not on the second gear is pushed, allowed. The coupling sleeve can be brought into engagement with the toothed wheel only if the teeth of the internal toothing can engage in the interdental spaces of the second toothed wheel. Thus, a synchronization of the coupling sleeve with the gear to be engaged is necessary, otherwise the teeth of the internal teeth abut against the teeth of the gear end face and thus preventing a coupling. The advantageous elastically deformable force transmission element serves to ensure that the movement generated by the eccentric unit is not transmitted to the clutch via a rigid connection. Rather, the force transmission element converts the movement of the eccentric unit or the adjusting device into a force to be transmitted by being elastically deformable. Deformation allows any movement but does not transmit it directly. Rather, an additional force component is generated. Advantageously, the force-transmitting element between the actuating rod and the coupling sleeve is arranged. Advantageously, the force-transmitting element is arranged between the actuating rod and the coupling sleeve such that when the actuating rod is displaced by the eccentric unit and the toothed coupling is not synchronized, the force-transmitting member is deformed to accommodate the movement of the actuating rod. However, once the gear coupling is synchronized, the coupling sleeve is pushed onto the gear due to the force stored in the elastically deformed force transmitting member and engaged therewith. In this way, it is ensured that the user can always operate the adjusting device and an automatic synchronization of the toothed coupling takes place. Advantageously, the force transmission element is designed as a spring element, in particular as a helical spring.
Weiterhin ist vorgesehen, dass die Fensterflügel jeweils eine Zahnstange aufweisen, die mit einem durch den Untersetzungsantrieb über die Kupplung antreibbaren Mitnahmemittel in Eingriff bringbar sind. Das bedeutet, dass die Kupplung beziehungsweise Zahnkupplung zwischen dem Untersetzungsantrieb und dem die Kraft beziehungsweise Bewegung auf die Fensterflügel übertragende Mitnahmemittel angeordnet ist. Vorteilhafterweise ist das Mitnahmemittel ein Zahnrad beziehungsweise ein Zahngetriebe und/oder ein Kettentrieb. Der Vorteil des Kettentriebs liegt darin, dass die Zahnstange des entsprechenden Fensterflügels mit der Kette über einen weiten Bereich in Eingriff stehen kann, sodass hohe Kräfte übertragbar sind.Furthermore, it is provided that the window sash each have a toothed rack, which can be brought into engagement with a drivable by the reduction drive via the clutch driving means. This means that the clutch or gear coupling is arranged between the reduction drive and the power or movement on the sash transferring driving means. Advantageously, the entrainment means is a gear or a toothed gear and / or a chain drive. The advantage of the chain drive is that the rack of the corresponding sash can engage the chain over a wide range, so that high forces can be transmitted.
Schließlich ist ein durch die Exzentereinheit auslösbarer Signalgeber zum Erfassen des Zustandes der Verstelleinrichtung vorgesehen, wobei bevorzugt ein Betätigungselement des Signalgebers durch die freie Mantelaußenfläche des Lagerrings und/oder Exzenterscheibe betätigbar beziehungsweise beaufschlagbar ist. Der Signalgeber kann beispielsweise dazu dienen, einer Steuereinrichtung mitzuteilen, ob die Kupplung geöffnet oder geschlossen ist. Die Steuereinrichtung kann daraufhin Funktionen des Dachschiebefensters freigeben oder sperren. Beispielsweise ist es denkbar, dass die Steuereinrichtung bei Erfassen des geöffneten Zustands der Kupplung die Stromzufuhr zu dem Untersetzungsantrieb unterbricht.Finally, a releasable by the eccentric signal generator for detecting the state of the adjusting device is provided, wherein preferably an actuating element of the signal generator by the free outer shell surface of the bearing ring and / or eccentric disc can be actuated or acted upon. The signal generator can serve, for example, to inform a control device whether the clutch is open or closed. The controller can then enable or disable functions of the roof sliding window. For example, it is conceivable that the control device interrupts the power supply to the reduction drive when detecting the open state of the clutch.

Weiterhin weist die Antriebseinheit 1 eine Verstelleinrichtung 14 auf, die manuell bedienbar ist und zum Betätigen der Kupplung 6 dient. Die Verstelleinrichtung 14 umfasst im Wesentlichen eine Exzentereinheit 15, eine mit der Exzentereinheit 15 wirkverbundene Betätigungsstange 16 sowie eine in einer Längsführung verschiebbar gelagerte Schlitteneinheit 17, die mit der Betätigungsstange 16 wirkverbunden ist, auf.Furthermore, the drive unit 1 an
Die Exzentereinheit 15 weist eine kreisförmige Exzenterscheibe 18 auf, die exzentrisch verdrehbar gelagert ist. Die
Der Lagerring 20 weist weiterhin eine Aufnahme 22 für die Betätigungsstange 16 auf. Im vorliegenden Ausführungsbeispiel ist die Aufnahme 22 als Gewindebohrung ausgebildet, in die die Betätigungsstange mit einem entsprechenden Gegengewinde eingeschraubt ist. Zweckmäßigerweise ist die Betätigungsstange 16 mittels einer Sicherungsmutter 23 auf dem Gegengewinde an dem Lagerring 20 gehalten. Weiterhin ist an der freien Stirnseite der Exzenterscheibe 18 ein Betätigungselement 24, vorliegend in Form eines Außen-Sechskants 25, angeordnet. An dem Betätigungselement 24 beziehungsweise an dem Außen-Sechskant 25 kann ein entsprechendes Werkzeug angreifen. Durch Verdrehen beziehungsweise Bedienen des Werkzeugs kann die Exzenterscheibe 18 um ihre Drehachse 19 exzentrisch verlagert/verdreht werden. Durch das Verdrehen der Exzenterscheibe 18 wird der Lagerring 20 in seiner Position verschoben, sodass diese im Wesentlichen translatorische Bewegung des Lagerrings 20 auf die Betätigungsstange 16 übertragen wird. Diese wiederum überträgt die Bewegung auf die Schlitteneinheit 17, welche mit der Kupplung 6 wirkverbunden ist, um Letztere zu betätigen.The bearing
Durch Bedienen der Verstelleinrichtung 14 mittels der Exzentereinheit 15 wird hier also die Kupplung 6 auf einfache Art und Weise manuell betätigt. Die Exzentereinheit 15 wirkt dabei auf die Betätigungsstange 16 im Wesentlichen wie ein Betätigungsnocken. Die Schulter 21 wirkt dabei gleichzeitig als Schutzvorrichtung, die ein Eindringen von Schmutz in das zwischen dem Lagerring 20 und der kreisförmigen Exzenterscheibe 18 gebildeten Gleitlager verhindert.By operating the adjusting

Weiterhin weisen die Kupplungsplatten 29, 30 koaxial zu den Vertiefungen 31 beziehungsweise 32 kreisförmige (Durch-)Bohrungen 33, 34 auf, deren Radius kleiner als der Radius der Vertiefungen 31, 32 ist.Furthermore, the
Die Kupplungsplatten 29 und 30 werden - wie später beschrieben - gegeneinander verspannt, sodass die Kupplungshülse 27 durch Verschieben der Kupplungsplatten 29 und 30 auf einfache Art und Weise betätigt werden kann. Die Zahnkupplung 26 weist weiterhin ein erstes Zahnrad 35 auf, das mit der in der
Weiterhin weist die Zahnkupplung 26 ein zweites Zahnrad 37 auf, das drehfest mit der Antriebswelle 7 des Kettentriebs 8, vorliegend ebenfalls mittels einer Madenschraube 38, verbunden ist. Beide Zahnräder 35 und 37 stehen in dem dargestellten Ausführungsbeispiel in Eingriff mit der Innenverzahnung 28 der Kupplungshülse 27. Die Zähne beziehungsweise Außenverzahnungen der Zahnräder 35 und 37 sind dabei ballig ausgeführt, sodass insbesondere ein Winkelversatz zwischen der Abtriebswelle des Untersetzungsantriebs 3 und der Antriebswelle 7 des Kettentriebs 8 ausgeglichen beziehungsweise kompensiert werden kann.Furthermore, the toothed coupling 26 has a

Das Profilelement 53 weist weiterhin an seiner Unterseite eine Längsführung 56 auf, die ebenfalls nutartig ausgebildet ist und einen Hinterschnitt aufweist, derart, dass die Schlitteneinheit 17 darin längsverschieblich formschlüssig gehalten gehalten ist. Die Schlitteneinheit 17 weist zwei Schlitten 57, 58 auf, die ein zu der Längsführung 56 komplementäres Außenprofil aufweisen. An dem Schlitten 58 ist ein Drehgelenk 59 fest angeordnet, an welchem die Betätigungsstange 16 gehalten ist. Die beiden Schlitten 57 und 58 sind über einen Schraubenbolzen 60 miteinander verbunden, der durch eine Bohrung des Schlittens 57 hindurchgreift, sodass der Schlitten 57 entlang des Schraubenbolzens 60 (axial) verschiebbar ist, und in eine Gewindebohrung des Schlittens 58 eingeschraubt ist. Zwischen den Schlitten 57 und 58 ist ein elastisch verformbares Kraft-Übertragungselement 61 angeordnet. In dem vorliegenden Fall ist dieses als Schraubenfeder 62 ausgebildet, durch welche der Schraubenbolzen 60 hindurchgeführt ist. Die Schraubenfeder 62 beaufschlagt die Schlitten 57 und 58 derart, dass sie auseinandergeschoben werden, sodass im entspannten Zustand der Schlitten 57 am Schraubenkopf 63 des Schraubenbolzens 60 anliegen würde.The

Das Profilelement 53 ist weiterhin stirnseitig an einem die Umlenkrollen 9, 10, 11 sowie das Zahnrad 12 lagernden (ortsfesten) Flanschelement 70 befestigt. An den dem Flanschelement 70 gegenüberliegenden Ende ist die Exzentereinheit 15 mittels einer Halteplatte 64 an dem Profilelement 53 gehalten.The
Im Folgenden soll die Funktionsweise des Dachschiebefensters 2 beziehungsweise der Verstelleinrichtung 14, im Wesentlichen bestehend aus der Exzentereinheit 15, der Betätigungsstange 16, der Schlitteneinheit 17, sowie den Kupplungsplatten 29 und 30, erläutert werden: Die
Zum Kuppeln muss die Verstelleinrichtung 14 entgegengesetzt bedient werden. Dazu wird die Exzentereinheit 15 entgegen des Pfeils 65 mittels des oben beschriebenen Werkzeugs verdreht, wodurch der Lagerring 20 sowie die Betätigungsstange 16 ebenfalls entgegen der Richtung des Pfeils 66 verlagert werden. Dadurch wird der Schlitten 58 der Schlitteneinheit 17 entgegen des Richtungpfeils 67 in der Längsführung 56 verschoben. Über die Schraubenfeder 62 wird die Bewegung auf den Schlitten 57 übertragen. Ist die Kupplung 6 synchronisiert, kann also die Kupplungshülse 27 auf das Zahnrad 37 aufgeschoben werden, weil die Zähne des Zahnrads 37 mit Zahnzwischenräumen der Kupplungshülse 27 fluchten, wird die Kupplung 6 gekuppelt. Ist die Kupplung 6 jedoch nicht synchronisiert, treffen also stirnseitig die Zähne des Zahnrads 37 auf die Zähne der Kupplungshülse 27, so wird die Bewegung des Schlittens 57 behindert und durch die Weiterbewegung des Schlittens 58 die Schraubenfeder 62 elastisch verformt, sodass der Schlitten 58 beziehungsweise Exzentereinheit 15 verstellt werden kann, ohne dass die Verstelleinrichtung 14 oder die Kupplung 6 beschädigt werden. Wird die Kupplungshülse 27 oder das Zahnrad 37 verdreht, sodass die Kupplung 6 synchronisiert ist, so sorgt die in der Schraubenfeder 62 gespeicherte Energie dafür, dass der Schlitten 57 entgegen der Richtung des Pfeils 67 verschoben und somit die Kupplungshülse 27 auf das Zahnrad 37 aufgeschoben und damit gekuppelt wird. Die Rückstellfedern 50 zwischen der Kupplungsplatte 30 und dem Halteflansch 46 sorgen als Druckfedern dafür, dass die Kupplung 6 stets in den gekuppelten Zustand gedrängt wird, sodass ein ungewolltes Entkuppeln der Antriebseinheit 1 während des Betriebs verhindert wird.For coupling the adjusting
Durch die manuell zu bedienende Verstelleinrichtung 14, mittels der die Kupplung 6 betätigbar ist, ist es auf einfache Art möglich, einen Defekt des Untersetzungsantriebs 3 beziehungsweise bei einem Stromausfall den Untersetzungsantrieb 3 von den Fensterflügeln zu trennen, sodass diese leicht per Hand in der Fensteröffnung verschiebbar sind. Damit wird gewährleistet, dass auch im Notfall das Dachschiebefenster von einem Benutzer auf einfache Art und Weise geöffnet oder geschlossen werden kann.By means of the manually operated adjusting
