Description

Die Erfindung betrifft eine Fensteranordnung nach dem Oberbegriff des Anspruchs 1. Die Erfindung betrifft außerdem eine Beschattungsvorrichtung für eine derartige Fensteranordnung.The invention relates to a window assembly according to the preamble of claim 1. The invention also relates to a shading device for such a window assembly.

An moderne Fensteranordnungen werden verschiedenste Aufgaben gestellt. Zum einen sollen diese eine besonders gute Wärmeisolierung aufweisen, um den Energieverbrauch bei der Heizung der angrenzenden Wohn- bzw. Arbeitsräume möglichst weit zu reduzieren. Andererseits sollen derartige Fenster aber auch weitere Funktionen erfüllen, wie beispielsweise eine einfache Bedienung und schnelle Belüftung der Wohn- und Arbeitsräume ermöglichen. Vielfach sind an derartigen Fensteranordnungen zudem Beschattungsvorrichtungen vorgesehen, die eine variable Beschattung der Wohn- oder Arbeitsräume ermöglichen. Schlussendlich sollen die verschiedenen Komponenten der Fensteranordnung auch vor Witterungseinflüssen geschützt werden und einfach zu reinigen sein.At modern window arrangements a variety of tasks are provided. On the one hand, these should have a particularly good thermal insulation in order to reduce the energy consumption in the heating of the adjacent living or working spaces as far as possible. On the other hand, such windows but also fulfill other functions, such as allow easy operation and rapid ventilation of the living and working spaces. In many cases shading devices are also provided on such window arrangements, which allow variable shading of the living or working spaces. Finally, the various components of the window assembly should be protected from the weather and be easy to clean.

Aus dem Stand der Technik ist es bekannt, sogenannte Verbundfenster vorzusehen, die dem aus früheren Zeiten bekannten Kastenfenster nachempfunden sind. Bei diesen besteht der Flügelrahmen aus einem inneren Rahmenteil mit einer Innenverglasung und einem äußeren Rahmenteil mit einer Außenverglasung, also aus zwei getrennt voneinander verbauten Verglasungen. Der Flügelrahmen kann mittels einer Öffnungsvorrichtung und Scharnieren geöffnet werden, wodurch ein Zwischenraum zwischen den Verglasungen zugänglich wird. Um eine variable Beschattung der Wohn- und Arbeitsräume zu ermöglichen, wird in diesem Zwischenraum eine Beschattungsvorrichtung in Form einer Jalousie oder eines Rollos vorgesehen. Zur Betätigung dieser Beschattungsvorrichtung werden mechanische Antriebe wie Seilzüge, Kurbelantriebe oder elektrische Antriebseinheiten in Form von Elektromotoren verwendet, wobei die entsprechend konfigurierte Beschattungsvorrichtung an einem Rahmenprofil des inneren oder äußeren Rahmenteils des Flügelrahmens befestigt wird. Aufgrund der komplexen mechanischen und/oder elektrischen Anbindung einer derartigen Beschattungsvorrichtung an dem Flügelrahmen ist die Montage jedoch kompliziert, so dass ein Austausch einer Beschattungsvorrichtung aufwendig und kostenintensiv ist. Endverbraucher, die eine Beschattungsvorrichtung beispielsweise zur Reparatur, zur Anpassung an geänderte Beschattungsbedürfnisse oder aus ästhetischen Gründen tauschen wollen, haben vielfach das Problem, dass dies nicht ohne Weiteres durchführbar ist. Problematisch ist zudem, dass die bekannten variablen Beschattungsvorrichtungen aufgrund ihrer Baugröße im eingefahrenen Zustand einen Teil des durch die Fensteranordnung hindurchtretenden Lichts blockieren.From the prior art it is known to provide so-called composite windows, which are modeled on the known from earlier times box window. In these, the sash consists of an inner frame part with an inner glazing and an outer frame part with an outer glazing, so two separately installed glazing. The sash can be opened by means of an opening device and hinges, making a space between the glazings accessible. In order to allow variable shading of the living and working spaces, a shading device in the form of a blind or blinds is provided in this space. To operate this shading device mechanical drives such as cables, crank drives or electric drive units are used in the form of electric motors, the appropriately configured shading device is attached to a frame profile of the inner or outer frame part of the sash. Due to the complex mechanical and / or electrical connection of such a shading device on the casement, however, the assembly is complicated, so that replacement of a shading device is complicated and expensive. End user who a shading device, for example, for repair, to To change adaptation to changed shading needs or for aesthetic reasons, often have the problem that this is not easily feasible. The problem is also that the known variable shading devices block a part of the light passing through the window assembly due to their size in the retracted state.

Gattungsgemäße Fensteranordnungen sind aus WO 02/084064 A1 und EP 2 733 296 A2 bekannt.Generic window arrangements are made WO 02/084064 A1 and EP 2 733 296 A2 known.

Aufgabe der Erfindung ist es deshalb, eine Fensteranordnung zu schaffen, die einen einfachen und schnellen Austausch der Beschattungsvorrichtung ermöglicht. Zudem soll eine Beschattungsvorrichtung mit möglichst geringem Platzbedarf geschaffen werden.The object of the invention is therefore to provide a window assembly that allows easy and quick replacement of the shading device. In addition, a shading device with the least possible footprint to be created.

Diese Aufgabe wird durch eine Fensteranordnung mit den Merkmalen des Anspruchs 1 und eine Beschattungsvorrichtung für eine derartige Fensteranordnung gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by a window assembly having the features of claim 1 and a shading device for such a window assembly. Advantageous embodiments of the invention are specified in the subclaims.

Bei der erfindungsgemäße Fensteranordnung ist die elektrische oder mechanische Antriebseinheit in einem Rahmenprofil des inneren Rahmenteils oder des äußeren Rahmenteils integriert ist. Dazu wird das Rahmenprofil so ausgebildet, dass die Antriebseinheit unsichtbar innerhalb des Rahmenprofils untergebracht werden kann. Durch die Trennung der Antriebseinheit von der Beschattungsvorrichtung wird einerseits erreicht, dass die mechanische und elektrische Anbindung der Antriebseinheit an dem Rahmenprofil bei einem Tausch der Beschattungsvorrichtung nicht gelöst werden muss, was den Austauschvorgang deutlich vereinfacht und damit auch für den Endverbraucher kostengünstig möglich ist. Damit kann auch der Endverbraucher die Beschattung den räumlichen Anforderungen anpassen, indem z.B. spezielle Rollos für Computerarbeitsplätze, Verdunklungsrollos, Sonnenschutzrollos oder Sonnenschutzjalousien selbst nachgerüstet oder getauscht werden. Andererseits kann durch die Integration der Antriebseinheit in das Rahmenprofil auch die Baugröße der Beschattungsvorrichtung reduziert werden, so dass bei eingefahrener Beschattungsvorrichtung mehr Licht durch die Fensteranordnung hindurch treten kann. Bei entsprechender Verbreiterung des Luftzwischenraums zwischen den Verglasungen können zudem auch zwei unterschiedliche Beschattungsvorrichtungen mit einem Antrieb eingesetzt werden, z.B. eine Außenjalousie für die Beschattung und ein Innenrollo für die optische Gestaltung. Erfindungsgemäß ist zudem die Beschattungsvorrichtung mittels einer lösbaren Befestigungsvorrichtung mit dem inneren Rahmenteil oder dem äußeren Rahmenteil verbunden. Eine derartige lösbare Befestigungsvorrichtung kann beispielsweise als Clips-Verbindung mit mindestens einem hakenförmigen elastischen Verbindungselement ausgebildet sein, es sind jedoch auch andere lösbare Verbindungsmittel, wie beispielsweise Magnete oder Klettverschluss, möglich. Hierdurch wird ein einfacher und schneller Austausch der Beschattungsvorrichtung ermöglicht und eine zeitaufwendige Demontage, wie sie beispielsweise bei Schraubverbindungen notwendig wäre, kann entfallen.In the window arrangement according to the invention, the electrical or mechanical drive unit is integrated in a frame profile of the inner frame part or of the outer frame part. For this purpose, the frame profile is formed so that the drive unit can be concealed within the frame profile. The separation of the drive unit from the shading device on the one hand ensures that the mechanical and electrical connection of the drive unit to the frame profile when replacing the shading device does not need to be solved, which significantly simplifies the exchange process and thus cost-effective for the end user. This allows the end user to adapt the shading to the spatial requirements, for example by retrofitting or replacing special roller blinds for computer workstations, blackout blinds, sunblinds or sunshades. On the other hand, by integrating the drive unit into the frame profile, the size of the shading device can also be reduced, so that more light can pass through the window arrangement when the shading device is retracted. With appropriate broadening of the air gap between the glazings also two different shading devices can be used with a drive, for example, an external blind for shading and a Interior roller blind for the optical design. According to the invention, the shading device is also connected to the inner frame part or the outer frame part by means of a detachable fastening device. Such a detachable fastening device may be formed, for example, as a clip connection with at least one hook-shaped elastic connecting element, but other releasable connecting means, such as magnets or Velcro, are also possible. As a result, a simple and quick replacement of the shading device is made possible and a time-consuming disassembly, as would be necessary for example in screw, can be omitted.

In einer vorteilhaften Ausführungsform kann eine Antriebswelle der Antriebseinheit aus dem Rahmenprofil des inneren oder äußeren Rahmenteils in den Innenraum hervortreten. Hierdurch wird eine besonders einfache funktionelle Schnittstelle zu der Beschattungsvorrichtung geschaffen. Es ist jedoch auch möglich, dass eine entsprechende Antriebswelle aus der Beschattungsvorrichtung hervorsteht.In an advantageous embodiment, a drive shaft of the drive unit can emerge from the frame profile of the inner or outer frame part in the interior. This creates a particularly simple functional interface to the shading device. However, it is also possible that a corresponding drive shaft protrudes from the shading device.

Bevorzugt kann die Antriebswelle der Antriebseinheit steckbar mit einem zumeist als Umlenkmechanismus ausgebildeten Betätigungsmechanismus in der Beschattungsvorrichtung verbunden sein. Dies kann beispielsweise über eine Steckverbindung mit einem polygonalen Querschnitt erfolgen, mittels derer das Antriebsmoment von der Antriebseinheit auf den Betätigungsmechanismus übertragen wird. Als übliche Querschnittsformen der Steckverbindung kommen beispielsweise Sechskant-Konturen oder rechteckige Konturen in Betracht. Durch die Steckverbindung wird ein einfacher Wechsel der Beschattungsvorrichtung ermöglicht, da hierdurch die Beschattungsvorrichtung einfach von der Antriebswelle abgezogen oder auf diese aufgesteckt werden kann. Wird die Antriebswelle an der Beschattungsvorrichtung ausgebildet, so ist die entsprechende Steckverbindung zwischen dem Betätigungsmechanismus und der Antriebseinheit auszubilden.Preferably, the drive shaft of the drive unit can be connected in a pluggable manner to an actuating mechanism, usually designed as a deflection mechanism, in the shading device. This can be done for example via a plug connection with a polygonal cross section, by means of which the drive torque is transmitted from the drive unit to the actuating mechanism. As a conventional cross-sectional shapes of the connector are, for example, hexagonal contours or rectangular contours into consideration. By the connector a simple change of the shading device is made possible, as this the shading device can be easily removed from the drive shaft or attached to this. If the drive shaft is formed on the shading device, then the corresponding plug connection between the actuating mechanism and the drive unit is to be formed.

Die Fensteranordnung kann dabei besonders vorteilhaft in dem Rahmenprofil des inneren Rahmenteils oder des äußeren Rahmenteils einen Energiespeicher zur Energieversorgung der elektrischen Antriebseinheit aufweisen. Hierdurch können aufwändige Verkabelungen zur Energieversorgung der Antriebseinheit in dem Rahmenprofil entfallen. Dies ist besonders von Vorteil, wenn das betreffende Rahmenteil als beweglicher Flügelrahmen ausgebildet ist. Zur Aufladung des Energiespeichers können an dem inneren Rahmenteil oder dem äußeren Rahmenteil zudem photovoltaische Zellen vorgesehen sein, so dass die Beschattungsvorrichtung autark betrieben werden kann und eine externe Energieversorgung nicht notwendig ist.In this case, the window arrangement can particularly advantageously have an energy store for supplying energy to the electric drive unit in the frame profile of the inner frame part or of the outer frame part. As a result, expensive wiring for supplying power to the drive unit in the frame profile can be omitted. This is particularly advantageous if the relevant frame part is designed as a movable sash. To charge the energy storage can on the inner frame part or the outer Frame part also be provided photovoltaic cells, so that the shading device can be operated independently and an external power supply is not necessary.

Vorteilhaft können das äußere Rahmenteil und/oder das innere Ralunenteil als Flügelrahmen ausgebildet sein. Dies ermöglicht ein einfaches Öffnen der Fensteranordnung und damit Belüften der Wohn- bzw. Arbeitsräume. Besonders günstig kann es sein, wenn die Fensteranordnung dabei als Verbundfenster ausgebildet ist, bei dem das als äußerer Flügelrahmen ausgebildete äußere Rahmenteil und das als innerer Flügelrahmen ausgebildete innere Rahmenteil beweglich, insbesondere gelenkig, miteinander verbunden sind. Zum Öffnen der Fensteranordnung kann dabei der Verbund aus äußerem und innerem Flügelrahmen gemeinsam geöffnet werden.Advantageously, the outer frame part and / or the inner Ralunenteil be designed as a sash. This allows easy opening of the window assembly and thus ventilate the living or working spaces. It may be particularly favorable if the window arrangement is designed as a composite window, in which the outer frame part formed as an outer sash and the inner frame part designed as an inner sash are movable, in particular articulated, connected to one another. To open the window assembly while the composite of outer and inner wing frame can be opened together.

Es wird außerdem eine Beschattungsvorrichtung für eine Fensteranordnung der beschriebenen Art beansprucht. Diese Beschattungsvorrichtung, die einen verstellbaren Beschattungsteil, ein Gehäuse und ein in dem Gehäuse angeordneten Betätigungsmechanismus für den verstellbaren Beschattungsteil aufweist, ist dadurch gekennzeichnet, dass dem Betätigungsmechanismus ein zur Steckverbindung ausgebildetes Verbindungselement für eine lösbare mechanische Kopplung des Betätigungsmechanismus mit der in dem Rahmenprofil des inneren Rahmenteils oder des äußeren Rahmenteils integrierten elektrischen oder mechanischen Antriebseinheit der Fensteranordnung zugeordnet ist. Hierdurch kann auf einfache Weise die Beschattungsvorrichtung durch Aufstecken auf das entsprechende Rahmenprofil der Fensteranordnung mit der dort angeordneten Antriebseinheit mechanisch antreibbar verbunden werden.It also claims a shading device for a window assembly of the type described. This shading device comprising an adjustable shading member, a housing and an adjustable shading member actuating mechanism disposed in the housing is characterized in that the actuating mechanism is a connector for releasably mechanically coupling the actuating mechanism to the frame profile of the inner frame member or the outer frame part is associated with integrated electrical or mechanical drive unit of the window assembly. In this way, the shading device can be mechanically driven in a simple manner by attaching to the corresponding frame profile of the window assembly with the drive unit arranged there.

In einer zweckmäßigen Ausführungsform kann das Verbindungselement als eine durch eine Durchgangsöffnung in dem Gehäuse hindurchragende Antriebswelle ausgebildet sein. In diesem Fall ist die Antriebswelle fest mit dem Betätigungsmechanismus verbunden und ein entsprechendes Adapterelement direkt an der Antriebseinheit im entsprechenden Rahmenprofil der Fensteranordnung ermöglicht die Steckverbindung mit der Antriebseinheit. Dies hat den Vorteil, dass bei demontierter Beschattungsvorrichtung keine Antriebswelle störend in den Zwischenraum der Fensteranordnung vorsteht und damit das Sichtfeld durch die Fensteranordnung nicht eingeschränkt wird, wodurch die Fensteranordnung problemlos auch ohne Beschattungsvorrichtung verwendet werden kann. Es ist jedoch auch möglich, das Verbindungselement als ein Adapterelement in dem Gehäuse des Betätigungsmechanismus zur Steckverbindung mit einer durch eine Durchgangsöffnung in dem Gehäuse hindurchragenden Antriebswelle einer Antriebseinheit auszubilden. In beiden Fällen wird auf einfache Weise die Beschattungsvorrichtung durch Aufstecken auf eine Antriebswelle bzw. ein Adapterelement einer Antriebseinheit mit dieser mechanisch antreibbar verbunden. Da die Antriebseinheit nicht in dem Gehäuse integriert, sondern von der Beschattungsvorrichtung getrennt ist, kann die Beschattungsvorrichtung besonders klein ausgebildet werden.In an expedient embodiment, the connecting element can be designed as a drive shaft projecting through a passage opening in the housing. In this case, the drive shaft is fixedly connected to the actuating mechanism and a corresponding adapter element directly to the drive unit in the corresponding frame profile of the window assembly allows the connector to the drive unit. This has the advantage that when disassembled shading device no drive shaft interfering projecting into the gap of the window assembly and thus the field of view is not limited by the window assembly, whereby the window assembly can be used without shading problem. However, it is also possible that Form connecting element as an adapter element in the housing of the actuating mechanism for plug-in connection with a through a through opening in the housing projecting drive shaft of a drive unit. In both cases, the shading device is connected by being plugged onto a drive shaft or an adapter element of a drive unit with this mechanically drivable in a simple manner. Since the drive unit is not integrated in the housing, but is separated from the shading device, the shading device can be made particularly small.

Die Beschattungsvorrichtung kann zweckmäßigerweise eine Befestigungsvorrichtung zur lösbaren Befestigung an dem inneren Rahmenteil oder dem äußeren Rahmenteil der beschriebenen Fensteranordnung aufweisen. Diese Befestigungsvorrichtung kann als Clips-Verbindung mit mindestens einem hakenförmigen elastischen Verbindungselement oder auch mit anderen lösbaren Verbindungsmitteln, wie beispielsweise Magneten oder Klettverschluss, ausgebildet sein. Bei einer Clips-Verbindung können anstelle der hakenförmigen Elemente die dazu korrespondierenden Hinterschneidungen an der Beschattungsvorrichtung angeordnet sein, wobei die hakenförmigen Elemente dann an dem inneren oder äußeren Rahmenteil angeordnet sind. Solche Beschattungsvorrichtungen können mit geringem Kraftaufwand und ohne Demontage weiterer Befestigungselemente einfach geradlinig abgezogen oder aufgesteckt werden, wobei gleichzeitig die Steckverbindung zwischen dem Betätigungsmechanismus und der Antriebseinheit gelöst bzw. verbunden wird.The shading device may expediently have a fastening device for releasable attachment to the inner frame part or the outer frame part of the described window arrangement. This fastening device may be formed as a clip connection with at least one hook-shaped elastic connecting element or with other releasable connecting means, such as magnets or Velcro. In a clip connection, the corresponding undercuts can be arranged on the shading device instead of the hook-shaped elements, wherein the hook-shaped elements are then arranged on the inner or outer frame part. Such shading devices can be simply removed or plugged straightforward with little effort and without disassembly of other fasteners, at the same time the connector between the actuating mechanism and the drive unit is released or connected.

Zweckmäßigerweise kann die Durchgangsöffnung zudem an einer Seite des Gehäuses angeordnet sein, die zur Anlage an einer Befestigungsfläche, beispielsweise dem Rahmenprofil einer beschriebenen Fensteranordnung, ausgebildet ist und gegebenenfalls der Antriebseinheit gegenüberliegt. Hierdurch ist die Durchgangsöffnung im montierten Zustand der Beschattungsvorrichtung nicht sichtbar, was für den ästhetischen Eindruck und zudem die Verschmutzungsempfindlichkeit günstig ist. Besonders vorteilhaft ist die Durchgangsöffnung und die Befestigungsvorrichtung an derselben Seite des Gehäuses, beispielsweise der Oberseite, angeordnet.Conveniently, the passage opening can also be arranged on one side of the housing, which is designed to bear on a mounting surface, for example, the frame profile of a described window assembly, and optionally opposite to the drive unit. As a result, the passage opening in the assembled state of the shading device is not visible, which is favorable for the aesthetic impression and also the sensitivity to contamination. Particularly advantageously, the passage opening and the fastening device on the same side of the housing, for example, the top disposed.

Weitere Besonderheiten und Vorzüge der Erfindung ergeben sich aus der folgenden Beschreibung eines bevorzugten Ausführungsbeispiels anhand der Zeichnung. Es zeigt:

einen Querschnitt durch den oberen horizontalen Abschnitt einer erfindungsgemäßen Fensteranordnung.
Other features and advantages of the invention will become apparent from the following description of a preferred embodiment with reference to the drawings. It shows:
Fig. 1
a cross section through the upper horizontal portion of a window assembly according to the invention.

In Fig. 1 ist die erfindungsgemäße Fensteranordnung 1 in einem Querschnitt gezeigt. Diese umfasst einen Blendrahmen 2 sowie ein in dem Blendrahmen 2 angeordnetes äußeres Rahmenteil 3 mit einer als Einfachglasscheibe ausgebildeten Außenverglasung 4 und ein inneres Rahmenteil 5 mit einer als Isolierglasscheibe ausgebildeten Innenverglasung 6. In einem Zwischenraum 7 zwischen dem äußeren Rahmenteil 3 und dem inneren Rahmenteil 5 ist eine Beschattungsvorrichtung 8 in Form einer Jalousie angeordnet, die einen in einem Gehäuse 9 untergebrachten Betätigungsmechanismus 10 und verstellbare Lamellen 11 als verstellbaren Beschattungsteil umfasst.In Fig. 1 the window assembly 1 according to the invention is shown in a cross section. This comprises a frame 2 as well as an outer frame part 3 arranged in the frame 2 with an outer glazing 4 formed as a single glass pane and an inner frame part 5 with an inner glazing 6 formed as an insulating glass pane. In an intermediate space 7 between the outer frame part 3 and the inner frame part 5 a shading device 8 is arranged in the form of a blind, which comprises an accommodated in a housing 9 actuating mechanism 10 and adjustable slats 11 as adjustable shading part.

Die Bezeichnungen "außen" und "innen" beziehen sich auf die Anordnung der Elemente in Bezug auf den Wohn- bzw. Arbeitsraum, der unter anderem durch die Fensteranordnung begrenzt wird. Dieser Wohn- bzw. Arbeitsraum liegt in der Darstellung von Figur 1 rechts neben der Fensteranordnung 1. Näher an diesem Wohn- bzw. Arbeitsraum liegende Elemente werden mit der Bezeichnung "innen" versehen, weiter weg liegende mit der Bezeichnung "außen".The terms "outside" and "inside" refer to the arrangement of the elements with respect to the living or working space, which is limited inter alia by the window arrangement. This living or working room is in the representation of FIG. 1 right next to the window arrangement 1. Closer to this living or working space lying elements are labeled "inside", further away with the label "outside".

Zur Betätigung der Beschattungsvorrichtung 8 ist eine elektrische Antriebseinheit 12 vorgesehen, die beispielsweise als Elektromotor ausgebildet sein kann. Diese elektrische Antriebseinheit 12 ist in einem Rahmenprofil 13 des inneren Rahmenteils 5 integriert. Zur Übertragung der Antriebsleistung von der Antriebseinheit 12 auf den Betätigungsmechanismus 10 der Beschattungsvorrichtung 8 ist ein Verbindungselement in Form einer Antriebswelle 14 vorgesehen. Das freie Ende der Antriebswelle 14 steht aus dem Rahmenprofil 13 in den Zwischenraum 7 hervor.For actuating the shading device 8, an electric drive unit 12 is provided, which may be formed, for example, as an electric motor. This electric drive unit 12 is integrated in a frame profile 13 of the inner frame part 5. For transmitting the drive power from the drive unit 12 to the actuating mechanism 10 of the shading device 8, a connecting element in the form of a drive shaft 14 is provided. The free end of the drive shaft 14 projects from the frame profile 13 into the intermediate space 7.

Zur kraft- und/oder formschlüssigen Befestigung der Beschattungsvorrichtung 8 an dem Rahmenprofil 13 des inneren Rahmenteils 5 ist eine als Clips-Verbindung ausgebildete lösbare Befestigungsvorrichtung 15 vorgesehen, die zwei gegenüberliegende hakenförmige und elastische Verbindungselemente 16 aufweist. Damit kann die Beschattungsvorrichtung 8 einfach und schnell von unten in die Befestigungsvorrichtung 15 eingeclipst bzw. nach unten ausgeclipst werden.For non-positive and / or positive fastening of the shading device 8 to the frame profile 13 of the inner frame part 5 designed as a clip-connection releasable fastening device 15 is provided which has two opposite hook-shaped and elastic connecting elements 16. Thus, the shading device 8 can be easily and quickly clipped from below into the fastening device 15 or clipped down.

Die Antriebswelle 14 der Antriebseinheit 12 ist mittels einer Steckverbindung mit dem Betätigungsmechanismus 10 der Beschattungsvorrichtung 8 verbunden. Damit wird bei dem Einclipsen der Beschattungsvorrichtung 8 in die Befestigungsvorrichtung 15 automatisch eine zuverlässige mechanische Verbindung zwischen der Antriebseinheit 12 und dem Betätigungsmechanismus 10 erreicht. Diese Steckverbindung ist in dem gezeigten Ausführungsbeispiel durch eine im Querschnitt sechskantförmige Antriebswelle 14 ausgebildet, die in ein als entsprechende Stecknuss ausgebildetes Adapterelement des Betätigungsmechanismus 10 eingesteckt wird.The drive shaft 14 of the drive unit 12 is connected by means of a plug connection with the actuating mechanism 10 of the shading device 8. Thus, when clipping the shading device 8 into the fastening device 15, a reliable mechanical connection between the drive unit 12 and the actuating mechanism 10 is automatically achieved. This connector is formed in the embodiment shown by a hexagonal drive in cross section drive shaft 14 which is inserted into a designed as a corresponding socket adapter element of the actuating mechanism 10.

Die Durchführung der Antriebswelle 14 durch das Gehäuse 9 der Beschattungsvorrichtung 8 erfolgt mittels einer Durchgangsöffnung 17, die an der Seite des Gehäuses 9 angeordnet ist, die zur Anlage an dem Rahmenprofil 13 des inneren Rahmenteils 5 ausgebildet ist und der Antriebseinheit 12 gegenüberliegt. Da die Beschattungsvorrichtung 8 in vertikaler Richtung in der Befestigungsvorrichtung 15 des Rahmenprofils 13 nach oben eingeclipst wird, ist die Durchgangsöffnung 17 an einer Oberseite des Gehäuses 9 angeordnet.The implementation of the drive shaft 14 through the housing 9 of the shading device 8 by means of a through hole 17 which is arranged on the side of the housing 9, which is designed to bear against the frame profile 13 of the inner frame member 5 and the drive unit 12 is opposite. Since the shading device 8 is clipped in the vertical direction in the fastening device 15 of the frame profile 13 upwards, the passage opening 17 is arranged on an upper side of the housing 9.

Die Energieversorgung der elektrischen Antriebseinheit 12 wird mittels eines Energiespeichers in Form eines Akkumulators bereitgestellt. Dieser Energiespeicher ist ebenfalls in dem Rahmenprofil 13 des inneren Rahmenteils 5 angeordnet und wird in der Darstellung in Figur 1 von der elektrischen Antriebseinheit 12 verdeckt. Zur Aufladung des Energiespeichers sind nicht dargestellte photovoltaische Zellen an der nach außen gewandten Seite des inneren Rahmenteils 5 angeordnet und elektrisch mit dem Energiespeicher verbunden. Zur Aufladung des Energiespeichers ist jedoch auch eine externe elektrische Energieversorgung denkbar, beispielsweise durch einen Kanals 18 in dem Rahmenprofil 13. In dem Kanal 18 kann jedoch auch eine zusätzliche Antriebswelle geführt sein, mit Hilfe derer bei einer zu geringen Energieversorgung durch den Energiespeicher die Antriebseinheit 12 von dem Wohn- bzw. Arbeitsraum aus manuell angetrieben werden kann.The power supply of the electric drive unit 12 is provided by means of an energy store in the form of a rechargeable battery. This energy store is likewise arranged in the frame profile 13 of the inner frame part 5 and is shown in FIG FIG. 1 obscured by the electric drive unit 12. To charge the energy storage photovoltaic cells, not shown, are arranged on the side facing the outward side of the inner frame part 5 and electrically connected to the energy storage. For charging the energy storage, however, an external electrical power supply is conceivable, for example by a channel 18 in the frame profile 13. In the channel 18, however, an additional drive shaft can be performed, with the help of which at too low a power supply through the energy storage, the drive unit 12th can be driven manually from the living or working space.

Bei dem gezeigten Ausführungsbeispiel sind das äußere Rahmenteil 3 und das innere Rahmenteil 5 als Flügelrahmen eines aus Aluminium, Kunststoff oder Holz bestehenden Verbundfensters ausgebildet. Dazu sind das äußere Rahmenteil 3 und das innere Rahmenteil 5 lösbar miteinander verbunden, was hier über eine Öffnungsvorrichtung und Scharniere erreicht wird. Der Verbund aus dem äußeren Rahmenteil 3 und dem inneren Rahmenteil 5 ist zusätzlich wie ein gewöhnliches Fenster mittels eines Drehgelenks schwenkbar bzw. kippbar mit dem Blendrahmen 2 verbunden und kann entsprechend geöffnet oder geschlossen werden. Durch diesen Verbund aus äußerem Rahmenteil 3 und innerem Rahmenteil 5 wird ein Flügelrahmen mit besonders guter Wärmeisolation gebildet. Zur Abdichtung dieses Verbunds gegenüber dem Blendrahmen sind eine äußere Dichtung 19, eine mittlere Dichtung 20 und eine innere Dichtung 21 vorgesehen. Zur Abdichtung des Zwischenraums 7 sind zudem weitere Zwischendichtungen 22 zwischen dem äußeren Rahmenteil 3 und dem inneren Rahmenteil 5 vorgesehen, wodurch die Wärmeisolation weiter verbessert wird.In the embodiment shown, the outer frame part 3 and the inner frame part 5 are formed as a sash frame of an existing aluminum, plastic or wood composite window. For this purpose, the outer frame part 3 and the inner frame part 5 are releasably connected to each other, which is achieved here via an opening device and hinges. The composite of the outer frame part 3 and the inner frame part 5 is additionally pivotable or tiltable like a normal window by means of a pivot joint connected to the frame 2 and can be opened or closed accordingly. Through this composite of outer frame part 3 and inner frame part 5 a sash is formed with particularly good thermal insulation. To seal this composite with respect to the frame, an outer seal 19, a middle seal 20 and an inner seal 21 are provided. For sealing the gap 7 further intermediate seals 22 are also provided between the outer frame part 3 and the inner frame part 5, whereby the heat insulation is further improved.

Soll beispielsweise die Beschattungsvorrichtung 8 bei der gezeigten Fensteranordnung 1 getauscht werden, können mittels der Öffnungsvorrichtung das innere Rahmenteil 5 und das äußere Rahmenteil 3 voneinander gelöst und um die Schwenkachse der Scharniere zueinander verschwenkt werden, wodurch der Zwischenraum 7 zugänglich wird. Mit geringem Kraftaufwand kann anschließend die alte Beschattungsvorrichtung nach unten ausgeclipst und die neue Beschattungsvorrichtung wieder eingeclipst werden.If, for example, the shading device 8 is to be exchanged in the window arrangement 1 shown, the inner frame part 5 and the outer frame part 3 can be detached from one another and pivoted relative to each other about the pivot axis of the hinges by means of the opening device, whereby the intermediate space 7 becomes accessible. With little effort then the old shading device can be clipped down and clipped the new shading device again.

In der gezeigten Ausführungsform ist die Beschattungsvorrichtung 8 über die Befestigungsvorrichtung 15 an dem Rahmenprofil 13 des inneren Rahmenteils 5 befestigt. Es ist jedoch auch möglich, die Beschattungsvorrichtung 8 in dem Zwischenraum 7 an dem äußeren Rahmenteil 3 zu befestigen. In diesem Fall ist dann die Antriebseinheit 12 entsprechend in einem Rahmenprofil des äußeren Rahmenteils 3 zu integrieren.In the embodiment shown, the shading device 8 is fastened to the frame profile 13 of the inner frame part 5 via the fastening device 15. However, it is also possible to fasten the shading device 8 in the intermediate space 7 on the outer frame part 3. In this case, then the drive unit 12 is to be integrated accordingly in a frame profile of the outer frame part 3.

Anstelle der Antriebswelle 14, die von der elektrischen Antriebseinheit 12 in den Zwischenraum 7 hineinragt, kann auch eine Antriebswelle vorgesehen sein, die von dem Betätigungsmechanismus 10 der Beschattungsvorrichtung 8 aus dem Gehäuse 9 hervorragt. In diesem Fall ist dann einen entsprechende Durchgangsöffnung in dem Rahmenprofil 13 und ein an der elektrischen Antriebseinheit 12 angeordnetes Adapterelement zur Aufnahme dieser Antriebswelle vorzusehen. Der Vorteil dieser Ausführungsform besteht darin, dass damit bei der erfindungsgemäßen Fensteranordnung keine Antriebswelle sichtbar in den Zwischenraum 7 hervorsteht, wenn keine Beschattungsvorrichtung installiert ist, und die Fensteranordnung folglich problemlos auch ohne Beschattungsvorrichtung verwendet werden kann.Instead of the drive shaft 14, which projects from the electric drive unit 12 in the intermediate space 7, and a drive shaft may be provided, which projects from the housing 9 of the actuating mechanism 10 of the shading device 8. In this case, a corresponding passage opening in the frame profile 13 and an arranged on the electric drive unit 12 adapter element for receiving this drive shaft is then provided. The advantage of this embodiment is that in the window assembly according to the invention no drive shaft visible in the gap 7 protrudes when no shading device is installed, and thus the window assembly can be used easily without shading device.
