Description

Die Erfindung betrifft gemäß dem Oberbegriff des Anspruchs 9 eine Gebäudeöffnungsverschattungsvorrichtung, insbesondere einen Rollladen mit einem eine motorgetriebene Wickelwelle mit Nothandkurbelgetriebe drehbar abstützenden Wickelwellenkasten, sowie eine Lageranordnung zur dreh- und ortsfesten Lagerung eines motorseitigen Endes der Wickelwelle der Gebäudeöffnungsverschattungsvorrichtung an einer zugeordneten Seite des Wickelwellenkastens gemäß dem Oberbegriff des Anspruchs 1.The invention relates according to the preamble of claim 9, a building opening shading device, in particular a roller shutter with a motor-driven winding shaft with Nothandkurbelgetriebe rotatably supporting winding shaft box, and a bearing assembly for rotatably and stationary mounting of a motor-side end of the winding shaft of Gebäudeöffnungsschwattungsvorrichtung on an associated side of the winding shaft box according to the Preamble of claim 1.

Bei Rollläden mit motorgetriebenen Wickelwellen sind sogenannte Nothandkurbeln weit verbreitet. Dabei kann über ein Getriebe eine Handkurbel im Versagensfall des Motors angesetzt werden, um den Behang zu bewegen. Antriebe für Wickelwellen von Rollläden und dergleichen sind dabei üblicherweise als Rohrmotoren ausgeführt, und mit ihrem aus der jeweiligen Wickelwelle ragenden Ende dreh- und ortsfest an dem zugeordneten Kastenseitenteil abgestützt.In roller shutters with motor-driven winding shafts so-called emergency manual cranks are widely used. In this case, a hand crank in case of failure of the engine can be attached via a gearbox to move the curtain. Drives for winding shafts of shutters and the like are usually designed as tubular motors, and rotatably supported with their projecting from the respective winding shaft end fixed to the associated box side part.

Ein Beispiel für die Lagerung eines motorseitigen Endes einer Wickelwelle ist der deutschen Gebrauchsmusterschrift DE 20 2009 003 226 U1 zu entnehmen. Dabei erfolgt die Abstützung des motorseitigen Endes der Wickelwelle über zwei dem Wickelwellenende und dem Kastenseitenteil zwischen geordnete Lagerplatten, von denen die Grundplatte mit einer einzigen Schraube an dem Seitenteil befestigt ist.An example of the storage of a motor-side end of a winding shaft is the German utility model DE 20 2009 003 226 U1 refer to. In this case, the support of the motor-side end of the winding shaft via two the winding shaft end and the box side part between ordered bearing plates, of which the base plate is fastened with a single screw on the side part.

Bei Antriebseinheiten mit Nothandkurbelgetrieben, die am Ende der Wickelwelle nicht nur auskragen, sondern auch in axialer Richtung relativ viel Platz beanspruchen ist eine solche Lagerung jedoch ungeeignet.For drive units with manual override gearboxes at the end of the winding shaft not only protrude, but also claim relatively much space in the axial direction, however, such storage is unsuitable.

Beim Einsatz von Antrieben mit zusätzlicher Nothandkurbel wird vielmehr herkömmlich mittels formschlüssiger Sechskantmuttern auf der Antriebsinnenseite und zugeordneten Schrauben, die von außen durch entsprechende Bohrungen an der Blendkappe bzw. am Kastenseitenteil eingeschraubt sind, die motorendseitige Lagerung der Wickelwelle am Seitenteil hergestellt. Im Revisionsfall sind die Schrauben jedoch meistens nicht mehr von außen zugänglich, da die Blendkappen oft innerhalb der Laibung montiert oder überdämmt werden.When using drives with additional emergency hand crank, the motor end-side mounting of the winding shaft on the side part is rather conventionally by means of positive hex nuts on the drive inside and associated screws, which are screwed from the outside through corresponding holes in the visor or on the box side. In the case of revision, however, the screws are usually no longer accessible from the outside, since the caps are often mounted or obscured within the soffit.

Weiterhin zeigen auch die deutsche Gebrauchsmusterschrift DE 20 2015 008 731 U1 und die europäische Patentanmeldung EP 1 106 773 A1 Lageranordnungen für die Lagerung eines motorseitigen Endes einer Wickelwelle, bei denen ein auskragender Abstützabschnitt am dem Kastenseitenteil zugewandten Ende der Wickelwelle mit einer am Seitenteil anzuschraubenden Lagerplattenanordnung in formschlüssigem Eingriff steht und dadurch drehfest am Seitenteil festgelegt ist. Im Revisionsfall müssen dabei jedoch Schraubverbindungen im Bereich oberhalb der Wickelwelle gelöst werden, die nur sehr schwer zugänglich sind.Furthermore, also show the German Utility Model DE 20 2015 008 731 U1 and the European patent application EP 1 106 773 A1 Bearing arrangements for the storage of a motor-side end of a winding shaft, in which a projecting support section on the box side part facing the end of the winding shaft is in a form-fitting engagement with a bearing plate assembly to be screwed on the side part and is thereby rotatably fixed to the side part. In case of revision, however, screw connections must be solved in the area above the winding shaft, which are very difficult to access.

Die deutsche Patentanmeldung DE 102 04 908 A1 zeigt in einer Ausführungsform einen Rollladen mit handgetriebener Wickelwelle, deren Getriebe mit einem Flansch eine Brücke hintergreift, die an der Kastenseitenwand unterseitig angeschraubt und oberseitig aufgesteckt ist. Auch dort ist die Verschraubung des auskragenden Getriebeflansches an der die Kastenseitenwand übergreifenden Brücke im Revisionsfall nicht oder nur sehr schwer lösbar.The German patent application DE 102 04 908 A1 shows in one embodiment a roller shutter with hand-driven winding shaft, the transmission with a flange engages behind a bridge, which is screwed to the side of the box side and attached on the top side. There, too, the screwing of the cantilever gear flange on the box side wall cross-bridge in the case of revision is not or only very difficult to solve.

Die deutsche Gebrauchsmusterschrift DE 202 07 441 U1 zeigt ebenfalls einen Rollladen mit handgetriebener Wickelwelle, bei dem sich das Kurbelgetriebe an der Kastenseitenwand abstützt und zwischen der Kastenseitenwand und einem Lagerflansch axialfest gehalten ist, wobei der Lagerflansch im Formschluss zweier Steckzapfen in das Getriebe eingreift und seinerseits an einer an der Kastenseitenwand angeschraubte Lagerplatte drehfest angebracht ist, so dass das Getriebe nicht nur axialfest, sondern auch drehfest gehaltert ist.The German Utility Model DE 202 07 441 U1 also shows a shutter with hand-driven winding shaft, in which the crank gear is supported on the box side wall and held axially fixed between the box side wall and a bearing flange, wherein the bearing flange engages in positive engagement of two spigot in the transmission and in turn to a on the Box side wall bolted bearing plate is rotatably mounted, so that the transmission is not only axially fixed, but also rotatably supported.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Gebäudeöffnungsverschattungsvorrichtung mit motorgetriebener Wickelwelle und Nothandkurbelgetriebe sowie eine Lageranordnung für das motorseitige Ende der Wickelwelle der Gebäudeöffnungsverschattungsvorrichtung zu schaffen, die einen einfachen Ausbau der Wickelwelle im Revisionsfall erlauben.Proceeding from this, the present invention seeks to provide a Gebäudeöffnungsverschattungsvorrichtung with motor-driven winding shaft and emergency manual crank gear and a bearing assembly for the motor end of the winding shaft of the building opening shading device, which allow easy removal of the winding shaft in case of revision.

Diese Aufgabe wird hinsichtlich der Gebäudeöffnungsverschattungsvorrichtung mit den Merkmalen des Anspruchs 9 gelöst, hinsichtlich der Lageranordnung mit den Merkmalen des Anspruchs 1.This object is achieved with respect to the building opening shading device with the features of claim 9, with regard to the bearing arrangement having the features of claim 1.

Gattungsgemäß weist die Lageranordnung neben den Kastenseitenteil eine Lagerplatte auf, über welche die Wickelwelle an dem an ihrem motorseitigen Ende auskragenden Getriebe an dem Seitenteil über lediglich auf ihrer im Einbauzustand nach unten gerichteten Seite vorgesehenen Schraubenaufnahmen an dem Seitenteil fixierbar ist. Weiterhin gattungsgemäß weist die Lagerplatte dabei einen im Einbauzustand das Getriebe umfangsseitig umgebenden Grundplattenabschnitt auf, an dem die Lagerplatte und das Seitenteil miteinander verschraubbar sind, sowie einen mit dem Grundplattenabschnitt verbundenen, das Getriebe im Einbauzustand auf seiner dem Seitenteil abgewandten Seite hintergreifenden Halteabschnitt. Der Grundplattenabschnitt und der Halteabschnitt sind dabei so ausgebildet, dass das Getriebe im Einbauzustand zwischen dem Seitenteil und Halteabschnitt axialfest aufgenommen ist bzw. von dem Seitenteil und dem Halteabschnitt axialfest gelagert ist. Weiterhin ist die Lagerplatte dabei so an das Getriebe angepasst, dass das Getriebe über die Lagerplatte und einen im Einbauzustand hergestellten Formschluss zwischen der mit dem Seitenteil verschraubten Lagerplatte und dem Getriebe drehfest am Seitenteil abgestützt ist.Generically, the bearing assembly in addition to the box side part on a bearing plate, via which the winding shaft is fixed to the protruding at its motor end gear on the side part on only on its in the installed state downwardly directed side screw receptacles on the side part. Furthermore generically, the bearing plate has a base portion which peripherally surrounds the gearbox in the installed state, on which the bearing plate and the side part can be screwed together, as well as a holding portion connected to the base plate portion, the gear being in the installed state on its side facing away from the side part. The base plate portion and the holding portion are formed so that the transmission is received axially fixed in the installed state between the side part and holding portion and is mounted axially fixed by the side part and the holding portion. Furthermore, the bearing plate is adapted to the gear so that the transmission is rotatably supported on the side part via the bearing plate and a positive engagement between the bearing plate bolted to the side part and the gearbox in the installed state.

Erfindungsgemäß weist der Halteabschnitt Haltelaschen auf, die von einer im Einbauzustand zur Wickelwellenachse normalen Ebene in einem das Getriebe umfangsseitig umgebenden Bereich axial von dem Seitenteil weg vorstehen und mit ihren Enden auf der dem Seitenteil abgewandten Seite des Getriebes das Getriebe hintergreifen und den Formschluss herstellen.According to the invention, the holding section has holding tabs which, from a plane normal to the axis of the winding shaft in the installed state, are in a gearbox Axially surrounding region circumferentially projecting away from the side part and engage behind with their ends on the side of the side facing away from the transmission and make the positive connection.

Die erfindungsgemäße Gebäudeöffnungsverschattungsvorrichtung, insbesondere ein Rollladen weist neben dem am motorseitigen Ende der Wickelwelle auskragenden Getriebe zum Anschluss einer Nothandkurbel an dem Motor am dortigen Wickelwellenende eine entsprechende Lageranordnung zur dreh- und ortsfesten Lagerung des motorseitigen Endes der Wickelwelle über das auskragende Nothandgetriebe auf.The building opening shading device according to the invention, in particular a roller shutter, in addition to the projecting at the motor end of the winding shaft gear for connecting a Nothandkurbel to the engine at the local winding shaft end a corresponding bearing assembly for rotatable and stationary mounting of the motor-side end of the winding shaft on the cantilever Nothandgetriebe.

Insgesamt ergibt sich somit eine besonders platzsparende Anordnung des mit einer gewissen Breite über die Wickelwelle auskragenden Nothandkurbelgetriebes insbesondere in axialer Hinsicht. Dadurch, dass sich das Getriebe direkt an der Kastenseitenwand abstützen kann und trotzdem über die das Getriebe umgebende Lagerplatte eine zuverlässige orts- und drehfeste Fixierung gegeben ist kann sichergestellt werden, dass der Behang der Gebäudeöffnungsverschattungsvorrichtung auch bei Einsatz von Nothandkurbelgetrieben bis ganz zum Rand der zu verschattenden Gebäudeöffnung geführt wird, also eine zuverlässige Verschattung bei hoher Windfestigkeit hergestellt wird, ohne dass die dortige Kastenseitenwand oberseitig über das Fenster überstehen muss, was oftmals baulich nicht möglich ist.Overall, this results in a particularly space-saving arrangement of the projecting with a certain width on the winding shaft emergency hand crank gear especially in the axial direction. The fact that the transmission can be supported directly on the box side wall and still a reliable location and rotationally fixed fixation is given over the gear surrounding the bearing can be ensured that the curtain of Gebäudeöffnungsverschattungsvorrichtung even with the use of emergency manual crank gears to the very edge of the shadowed Building opening is performed, so a reliable shade with high wind resistance is produced without the local box side wall must survive on the top side over the window, which is often structurally impossible.

Über die Haltelaschen kann das Getriebe dabei einerseits gegen die Kastenseitenwand gedrückt werden, um es axial festzulegen, andererseits kann der zur Drehsicherung nötige Formschluss hergestellt werden.On the one hand, the gear can be pressed against the box side wall via the retaining tabs, in order to fix it axially, on the other hand, the necessary form-fit can be made for rotational security.

Vorteilhaft lässt sich die Lagerplatte dabei nicht nur beim Einbau einfach vom dem Motor abgewandten Ende der Wickelwelle her auf die Wickelwelle aufsetzen und dann nach Anbringen der Wickelwelle im Wickelwellenkasten an der unterseitigen Verschraubung eben dort fixieren, sondern vor allem im Revisionsfall, also etwa bei einem Versagen des Wickelwellenmotors auch einfach wieder demontieren.Advantageously, the bearing plate can not just put it on installation of the motor facing away from the end of the winding shaft forth on the winding shaft and then fix it after attaching the winding shaft in the winding shaft box on the bottom screw just there, but especially in case of revision, so about a failure The winding shaft motor also easy to disassemble again.

Denn zum einen reicht es zum Lösen der Lagerplatte vom Kastenseitenteil aus, die unterseitige und damit von unten her durch die üblicherweise an Wickelwellenkästen vorgesehene Revisionsklappe zugängliche Verschraubung zu lösen. Zum Anderen kann dadurch, dass zwischen dem Getriebe und der Lagerplatte lediglich Formschluss besteht, also keine weitere Verschraubung oder dergleichen nötig ist, die Lagerplatte einfach nach hinten weg vom Getriebe abgezogen werden.For one thing, it is sufficient to release the bearing plate from the box side part, the bottom and thus accessible from below by the usually provided on winding shaft boxes inspection flap accessible screw. On the other hand, the fact that between the transmission and the bearing plate only form-fitting, so no more screwing or the like is necessary, the bearing plate are simply pulled back away from the gearbox.

Besonders einfach lässt sich die Wickelwelle dann aus ihrer Position im Wickelwellenkasten entnehmen, wenn am dem Motor gegenüberliegenden Ende der Wickelwelle eine sogenannte federnde Achskappe, d. h. ein in Axialrichtung verschiebbar an der Wickelwelle angebrachter Lagerbolzen vorgesehen ist, wie beispielsweise der deutschen Patentanmeldung DE 10 2013 000 278 A1 oder der europäischen Patentschrift EP 1 476 244 B1 zu entnehmen ist, die hier diesbezüglich mit einbezogen werden.The winding shaft can then be removed from its position in the winding shaft case particularly simply if a so-called resilient axle cap, ie a bearing bolt mounted so as to be displaceable on the winding shaft in the axial direction, is provided on the end of the winding shaft, for example the German patent application DE 10 2013 000 278 A1 or the European patent specification EP 1 476 244 B1 which are included in this regard.

Gemäß einer weiteren vorteilhaften Weiterbildung besteht die Lagerplatte aus zwei Teilen, nämlich einer den Grundplattenabschnitt ausbildenden Grundplatte und einer den Halteabschnitt ausbildenden Halteplatte, die miteinander fest verbunden sind. Denn es hat sich gezeigt, dass häufig die gleichen Wickelwellen mit den gleichen Antrieben in unterschiedlichen Kästen eingesetzt werden, auch abhängig von der Art und Länge des Behangs. Dabei kann durch die zweiteilige Ausbildung der Lagerplatte eine höhere Gleichteiligkeit erreicht werden, weil die Halteplatte für alle Kästen gleich sein kann, wohingegen lediglich die Grundplatte an den jeweiligen Kasten angepasst sein muss. Das Gleiche gilt selbstverständlich auch im umgekehrten Fall, wenn unterschiedliche Getriebe in den selben Wickelwellenkasten eingebaut werden sollen, wobei dann die Grundplatte immer die selbe sein kann und lediglich die Halteplatte ausgetauscht werden muss.According to a further advantageous embodiment, the bearing plate consists of two parts, namely a base plate forming the base plate and a holding portion forming the holding plate, which are fixedly connected to each other. Because it has been shown that often the same winding shafts are used with the same drives in different boxes, also depending on the type and length of the curtain. It can be achieved by the two-part design of the bearing plate a higher common parts, because the retaining plate for all boxes can be the same, whereas only the base plate must be adapted to the respective box. The same applies, of course, in the opposite case, if different gear in the same winding shaft box to be installed, in which case the base plate can always be the same and only the plate must be replaced.

Halte- und Grundplatte könnten dabei theoretisch miteinander verschraubt sein, da diese Verschraubung im Revisionsfall nicht unbedingt gelöst werden muss. Vorteilhaft ist es jedoch, wenn die Halte- und die Grundplatte miteinander vernietet sind. Denn dadurch erhält man eine kostengünstige und platzsparende Verbindung der beiden Teile. Auch eine Schweiß- und Lötverbindung wäre theoretisch denkbar.Holding and base plate could theoretically be screwed together, since this screw connection does not necessarily have to be solved in the case of revision. It is advantageous, however, if the holding and the base plate riveted together are. Because this gives you a cost-effective and space-saving connection of the two parts. A welding and soldering connection would be theoretically conceivable.

Dazu könnten die Haltelaschen so ausgebildet sein, dass sie mit ihren Enden formschlüssig in Ausnehmungen an der dem Seitenteil abgewandten Rückseite des Getriebes der Gebäudeöffnungsverschattungsvorrichtung eingreifen. Alternativ und ergänzend wäre es auch denkbar, die Mehrzahl von Haltelaschen so über den Umfang des Getriebes zu verteilen, dass sich der Formschluss an der Umfangsseite des Getriebes ergibt.For this purpose, the retaining tabs could be formed so that they engage positively with their ends in recesses on the rear side facing away from the side part of the transmission of the building opening shading device. Alternatively and additionally, it would also be conceivable to distribute the plurality of retaining tabs over the circumference of the gearbox such that the positive locking results on the peripheral side of the gearbox.

Besonders zuverlässig ist die Lagerung der Wickelwelle an ihrem motorseitigen Ende, wenn die Lagerplatte das Getriebe ringförmig umgibt, also vollständig einschließt und nicht nur auf einer Seite überbrückt.Particularly reliable is the storage of the winding shaft at its motor end, when the bearing plate surrounds the gear ring, so completely encloses and not only bridged on one side.

Zum Einbau wird die Wickelwelle 3 mit ihrem verschiebbar aufgenommenen Lagerbolzen 6 an einem zugeordneten Kastenseitenteil des Wickelwellenkastens angesetzt, der Lagerbolzen eingedrückt und dann die Wickelwelle 3 mit ihrem motorseitigem Ende nach oben eingeschwenkt. Anschließend muss die Wickelwelle 3 an ihrem motorseitigen Ende an einem in Figur 1 dargestellten, zugeordneten Kastenseitenteil 1 axial- und drehfest angebracht werden. Dazu ist eine aus einer Grundplatte 4 und einer Halteplatte 5 bestehende Lagerplatte 4, 5 vorgesehen, wobei die Lagerplatte 4, 5 anders als in der Darstellung in einem Stück, d. h. bei miteinander vernieteter Grundplatte 4 und Halteplatte 5 vor dem Ansetzen des Lagerbolzens 6 von hinten auf die Wickelwelle 3 aufgeschoben wird.First, reference is made to the FIG. 1 , which shows a motor-driven winding shaft 3 of a shutter, which has an axially projecting and radially projecting Nothandkurbelgetriebe 2 at its motorseitigem end, and at its other end remote from the engine slidably received against spring force bearing pin 6. For installation is the Winding shaft 3 with its slidably received bearing pin 6 attached to an associated box side part of the winding shaft box, the bearing pin pressed and then the winding shaft 3 with its motorseitigem end pivoted upwards. Subsequently, the winding shaft 3 at its motor end at an in FIG. 1 shown, associated box side member 1 are mounted axially and rotationally fixed. For this purpose, a consisting of a base plate 4 and a support plate 5 bearing plate 4, 5 is provided, wherein the bearing plate 4, 5 differently than in the illustration in one piece, ie riveted together with base plate 4 and retaining plate 5 before attaching the bearing pin 6 from the rear is pushed onto the winding shaft 3.

Die Halteplatte 5 ist der Figur 2 im Einzelnen zu entnehmen, die Grundplatte 4 der Figur 3. Die beiden Platten 4, 5 werden dabei zusammengenietet, allerdings in um 180 Grad gedreht der Stellung der Grundplatte 4. Dafür sind an einem ringförmigen Bodenabschnitt der Grundplatte 4 und an einem ebenfalls umlaufenden Bodenabschnitt der Halteplatte 5 entsprechende Bohrungen vorgesehen, die Markierungen tragen, um das Vernieten zu erleichtern.The holding plate 5 is the FIG. 2 to see in detail, the base plate 4 of FIG. 3 , The two plates 4, 5 are riveted together, but rotated in 180 degrees to the position of the base plate 4. For corresponding holes are provided on an annular bottom portion of the base plate 4 and on a likewise circumferential bottom portion of the support plate 5, carry the markings to the To facilitate riveting.

Die Halteplatte 5 weist dabei zwei von ihren Bodenabschnitt abgekröpfte Haltelaschen 8 auf, die, wie Figur 4 zeigt, im Einbauzustand das Getriebe 2 formschlüssig hintergreifen. Die Grundplatte 4 weist ebenfalls zwei abgekröpfte Laschen 9, 10 auf, die im zusammengenieteten Zustand der Lagerplatte 4, 5 in die gleiche Richtung, nämlich vom Seitenteil 1 weg vom Bodenabschnitt abstehen und zur drehfesten Anbindung an das Seitenteil 1 dienen.The holding plate 5 has two bent from their bottom portion retaining tabs 8, which, as FIG. 4 shows, in the installed state, the gear 2 engage behind a positive fit. The base plate 4 also has two bent tabs 9, 10 which protrude in the riveted state of the bearing plate 4, 5 in the same direction, namely from the side part 1 away from the bottom portion and serve for rotationally fixed connection to the side part 1.

Zum einen ist ein vom Bodenabschnitt der Grundplatte 4 ins Kasteninnere abgekröpfter Verschraubungssteg 9 vorgesehen, welcher eine Randkerbe zur Aufnahme einer Schraube trägt, dem am Seitenteil 1 eine im unteren Bereich des Seitenteils 1 angeformte, sich zum Kasteninneren hin öffnende Verschraubungbuchse zugeordnet ist. Zum anderen ist gegenüber des Verschraubungsstegs 9 ein vom Bodenabschnitt der Grundplatte 4 ins Kasteninnere abgekröpfter Formschlusssteg 10 vorgesehen, welcher eine Randkerbe zur Aufnahme einer entsprechenden Formschlussfeder aufweist, welche im oberen Bereich des Seitenteils 1 angeformt ist und dort zum Kasteninneren hin vorspringt. Zum Befestigen und/ oder Lösen der Lagerplatte 4, 5 am bzw. vom Seitenteil 1 ist vom Monteur also lediglich eine einzige Schraube zu betätigen, die zudem im unteren Bereich des Kastenseitenteils 1 bei Öffnen der Revisionsklappe des Wickelwellenkastens einfach zugänglich ist.On the one hand, a cranked web 9 is provided, which has an edge notch for receiving a screw and which is formed on the side part 1 in the lower region of the side part 1, which opens towards the inside of the box and which is screwed from the bottom part of the base plate 4 into the box. On the other hand, in comparison with the screwed web 9, a form-fitting web 10 bent from the bottom section of the base plate 4 into the interior of the box is provided, which has a Having edge notch for receiving a corresponding positive-locking spring, which is formed in the upper region of the side part 1 and projects there to the box interior. To attach and / or release the bearing plate 4, 5 on or from the side part 1 is therefore only a single screw to actuate the installer, which is also easily accessible in the lower part of the box side part 1 when opening the access door of the winding shaft box.

Dadurch, dass die Lagerplatte 4, 5 das Getriebe ringförmig umgibt und das Getriebe sich mit seiner Stirnseite an der Innenwand des Kastenseitenteils 1 abstützen kann, wobei die Drehfixierung über den rückseitigen Formschluss am Getriebe 2 und die beiden Stege 9, 10 am Seitenteil 1 erfolgt, wird die bei herkömmlicher Verschraubung nötige Wandstärke der Motorlagerplatte eingespart, wodurch entsprechend mehr Platz für den Behang ist, der entsprechend breiter und damit windstabiler ausgeführt werden kann.Characterized in that the bearing plate 4, 5 surrounds the gear ring and the transmission can be supported with its front side on the inner wall of the box side part 1, wherein the rotational fixation on the rear form fit on the gear 2 and the two webs 9, 10 takes place on the side part 1, the necessary wall thickness of the motor bearing plate is saved in conventional screw, which is correspondingly more space for the curtain, which can be made correspondingly wider and thus more stable to wind.

Abwandlungen und Modifikationen der gezeigten Ausführungsform sind möglich, ohne den Rahmen der Erfindung zu verlassen.Modifications and modifications of the illustrated embodiment are possible without departing from the scope of the invention.
