Abstract

A driving gear for a roller shutter (12), a Venetian blind or the like is illustrated and described, with a winding shaft for the roller shutter armour (12a) and with a gear which sets the shaft in rotation and which has, arranged on the front side of and connected in a rotationally fixed manner to the winding shaft, a gear wheel (26), with which a drive pinion (28), which is arranged on a drive shaft arrangement (33), meshes, the winding shaft, the gear wheel (26) and the drive pinion (28) moreover being arranged in a roller shutter casing (14) mounted in particular on the masonry, and the drive shaft (29; 39), which in projection runs at an angle on the transverse plane of the winding shaft, reaching outwards through the wall of the roller shutter casing (14) in a wall bearing (21). In order to achieve a compact gear construction as well as as extensive as possible a wing opening, the wall bearing (21) is arranged on a lateral end wall (18) of the roller shutter casing (14), the drive shaft arrangement (33) being designed as an angular gear having three shaft sections (20, 34, 29; 39, 40, 41), the inner shaft section of which forms the drive shaft (29; 39) bearing the drive pinion (28), the central shaft section (34) of which is supported in the wall bearing (21) and the outer shaft section (20) of which is designed for connection of a rotary handle such as a crank handle (22) or the like. As a result, with very compact construction of the whole gear arrangement, it is brought about that the drive parts are freely accessible from the side and do not stand in the way of more extensive wing opening. <IMAGE>

Description

Die Erfindung betrifft einen Antrieb für einen Rolladen, eine Jalousie od. dgl., mit einer Wickel­welle für den Rolladenpanzer und mit einem diese in Drehung versetzenden Getriebe, welches ein stirn­seits der Wickelwelle angeordnetes sowie drehfest mit dieser verbundenes Getrieberad aufweist, mit dem ein an einer Antriebswellen-Anordnung angeord­netes Antriebritzel kämmt, wobei ferner die Wickel­welle, das Getrieberad und das Antriebritzel in einem insbesondere auf das Mauerwerk aufgesetzten Rolladenkasten angeordnet sind und die in der Projektion auf die Querebene der Wickelwelle schräg verlaufende Antriebswelle die Wandung des Rolla­denkastens in einem Wandlager nach außen durch­greift.The invention relates to a drive for a roller shutter, a blind or the like., With a winding shaft for the roller shutter curtain and with a gear that sets this in rotation, which has a front end of the winding shaft and non-rotatably connected with this gearwheel, with which a Drive shaft arrangement arranged drive pinion combs, furthermore the winding shaft, the gear wheel and the drive pinion are arranged in a roller shutter box, in particular placed on the masonry, and the drive shaft which runs obliquely in the projection onto the transverse plane of the winding shaft extends through the wall of the roller shutter box to the outside in a wall bearing .

Ein derartiger Antrieb ist durch offenkundige, druckschriftlich nicht belegbare Vorbenutzung bekannt. Getrieberad und Antriebsritzel sind in einem auf der Innenseite der Rolladenkastenstirn­wand angebrachten Griebegehäuse gelagert, an dem auch eine Führung für die Antriebswelle vorgesehen ist. Die Antriebswelle liegt auf der Innenseite des rolladenwellenfesten Getrieberades. In der Projek­tion auf die Strinseite der Wickelwelle verläuft die Antriebswelle schrägen nach unten und führt in einem Wandlager aus der unteren Wand des Rolla­denkastens unmittelbar vor dem seitlichen Holm des Blendrahmens heraus. Konstruktionsbedingt ist die Antriebswelle bzw. die Antriebswellen-Andornung in einer zur Stirnwand des Rolladenkstens parallelen Ebene verlaufend vorgesehen. Die von außen für einen manuellen oder auch motorischen Antrieb zugängliche Antriebswelle bzw. deren Ende ist raumseits nahe dem Eckbereich des Roladenkastens und vor dem Eckbereich des Fenster- bzw. Türrahmens angeordnet. Der Vorteil dieser Anordnung besteht darin, daß die Betätigung des Rolladenantriebs dank der guten Erreichbarkeit der Antriebswelle einfach ist. Nachteilig ist aber einerseits, daß die aus dem Rolladenkasten ragenden Antriebsteile störend sichtbar bleiben. Vor allem jedoch verhindert die Anordnung eine über einen rechten Winkel hinaus­gehende Öffnung des Fenster- oder Türflügels, die bauseits dann möglich wäre, wenn - wie in südli­chen Ländern üblich - der Mauersturz nicht oder nicht wesenlich über die rauminnere Ebene des Blendrahmens hinausragt.Such a drive is known from obvious prior use, which cannot be documented in printed form. The gearwheel and drive pinion are mounted in a gullet housing on the inside of the roller shutter box end wall, on which a guide for the drive shaft is also provided. The drive shaft lies on the inside of the gear wheel fixed to the roller shutter shaft. In the projection onto the string side of the winding shaft, the drive shaft runs obliquely downwards and leads in a wall bearing out of the lower wall of the roller shutter box directly in front of the side rail of the frame. Due to the design, the drive shaft or the drive shaft mandrel is parallel to the front wall of the roller shutter Provided level. The drive shaft or its end, which is accessible from the outside for a manual or motorized drive, or its end is arranged on the room side near the corner area of the roller shutter box and in front of the corner area of the window or door frame. The advantage of this arrangement is that the operation of the shutter drive is easy thanks to the easy accessibility of the drive shaft. On the one hand, it is disadvantageous that the drive parts protruding from the roller shutter box remain disruptively visible. Above all, however, the arrangement prevents an opening of the window or door leaf that extends beyond a right angle, which would be possible on site if - as is customary in southern countries - the lintel does not protrude, or does not substantially protrude beyond the inner plane of the window frame.

Hier setzt die Erfindung ein. Ihr liegt im wesentlichen die Aufgabe zugrunde, einen Antrieb der im Oberbegriff des Anspruchs 1 näher umrissenen Art verfügbar zu machen, der unter Beibehaltung einfachster Bedienbarkeit des Antriebs eine weiter­gehende Flügelöffnung, insbesondere eine solche von etwa 180°, erlaubt. Die zur Lösung dieses seit langem bestehenden Problems heranzuziehenden Mittel sollen dabei einfacher und preiswerter Natur sein.This is where the invention comes in. It is based essentially on the task of making a drive available of the type outlined in the preamble of claim 1 which, while maintaining simple operation of the drive, permits a wider wing opening, in particular one of approximately 180 °. The means to be used to solve this long-standing problem should be simple and inexpensive in nature.

Die Erfindung löst diese Aufgabe in erster Linie und im wesentlichen dadurch, daß das Wand­lager an einer seitlichen Stirnwand des Rolla­denkastens angeordnet ist, daß die Antriebswellen-­Anordnung als drei Wellenabschnitte aufweisendes Winkelgetriebe ausgebildet ist, deren innerer Wellenabschnitt die das Antriebsritzel tragende An­triebswelle ausbildet, deren mittlerer Wellen­abschnitt in dem Wandlager abgestützt ist und deren äußerer Wellenabschnitt zum Anschluß einer Dreh­handhabe wie Handkurbel od. dgl. ausgebildet ist.The invention solves this problem primarily and essentially in that the wall bearing is arranged on a lateral end wall of the roller shutter box, that the drive shaft arrangement is designed as an angular gear having three shaft sections, the inner one Shaft section which forms the drive shaft carrying the drive pinion, the central shaft section of which is supported in the wall bearing and the outer shaft section of which is designed to connect a rotary handle such as a hand crank or the like.

Hierdurch wird bei sehr kompakter Bauweise der gesamten Getriebeanordnung erreicht, daß der An­trieb frei von der Seite her zugänglich wird. Antriebsteile stehen folglich einer weitergehenden Flügelöffnung nicht mehr im Wege. Die Antriebswelle kann mit erheblichem Vorteil in der Projektion auf die Ebene des herabgelassenen Rolladenpanzers schräg verlaufen, denn da die Antriebswelle somit nicht nur zu Seite verlagert ist, sondern dort aufgrund ihrer zweiten Schräglage in Richtung zur Rolladenkasten-Frontseite weist, bleibt der Antrieb frei und mühelos zugänglich. Ein nach der Erfindung gestalteter Antrieb läßt es auch ohne weiteres zu, die Handkurbel mit dem Antriebswellenende ständig verbunden zu lassen, zumal sämtliche Teile in ihrer neuen Anordnung hinter Vorhängen verborgen werden können. In weiter Ausgestaltung kann die Antriebs­wellen-Andornung als Doppel-Kardanwelle ausgebildet sein, deren mittlerer Kardanwellenabschnitt in dem Wandlager gelagert ist.In this way, with a very compact design of the entire gear arrangement, the drive is freely accessible from the side. Drive parts are therefore no longer in the way of further wing opening. The drive shaft can run with a significant advantage in the projection onto the level of the lowered roller shutter curtain, because since the drive shaft is not only shifted to the side, but points there due to its second inclined position towards the front of the roller shutter box, the drive remains free and effortless accessible. A drive designed according to the invention also allows the hand crank to be permanently connected to the drive shaft end, especially since all the parts in their new arrangement can be hidden behind curtains. In a further embodiment, the drive shaft assembly can be designed as a double cardan shaft, the central cardan shaft section of which is mounted in the wall bearing.

Eine Alternative sieht vor, daß die Antriebs­wellen-Anordnung als dreiteiliges Kegelrad-Win­kelgetriebe ausgebildet ist, dessen Antriebswelle in der Projektion auf die Ebene des herabgelassenen Rolladenpanzers im wesentlichen lotrecht verläuft.An alternative provides that the drive shaft arrangement is designed as a three-part bevel gear angular gear, the drive shaft of which runs essentially perpendicular in the projection onto the level of the lowered roller shutter curtain.

Für beide Ausführungsvarianten ist es vorteil­haft, wenn die Zwischenwelle die Stirnwand des Rolladenkastens durchgreift und außerhalb derselben mittels einer Hutze gekapselt ist.For both variants, it is advantageous if the intermediate shaft extends through the end wall of the roller shutter box and is encapsulated outside by means of a scraper.

Zur weiteren Förderung der platzsparenden Bauweise kann entsprechend einem weiteren Erfin­dungsmerkmal die seitliche Wand des Rolladenkastens zur Aufnahme von bzw. zur Bildung von Getriebe-­Lagerteilen kammerartig profiliert ausgebildet sein, wobei schräg verlaufende Kammern gebildet sind, die teils innerhalb, teils außerhalb der Hauptwandebene verlaufen. Entsprechend können die Getriebeteile im engen Bereich vor und hinter der Hauptwandebene auf axial dichtem Raum untergebracht werden.To further promote the space-saving design, according to a further feature of the invention, the side wall of the roller shutter box for receiving or forming gearbox bearing parts can be profiled in a chamber-like manner, oblique chambers being formed, some of which run inside, some outside of the main wall plane. Accordingly, the gear parts can be accommodated in the narrow area in front of and behind the main wall level in an axially tight space.

Im übrigen versetht sich die Erfindung am besten anhand der nachfolgenden Beschreibung zweier in den Zeichnungen dargestellter Ausführungsbei­spiele. In den Zeichnungen zeigen am Beispiel eines Fensters:

  • Fig. 1 einen Eckausschnit eines Fensters mit darüber befindlichem Rolladenkasten als Übersicht,
  • Fig. 2 eine Seitenansicht in Richtung der Ansichtspfeiles II der Fig.1,
  • Fig. 3 einen fensterebenen-parallelen Längs­schnitt durch den Antrieb, wobei zwei Anordnungen einer ersten Ausführungsvariante gemeinsam darge­stellt sind,
  • Fig. 4 eine schematische Stirnansicht in Richtung des Ansichtspfelies IV der Fig. 3,
  • Fig. 5 eine der Fig. 3 entsprechende Dartsel­lung einer Antriebsalternative, und
  • Fig. 6 eine Stirnsansicht in Richtung des Ansichtspfeiles VI der Fig. 5.
For the rest, the invention is best understood based on the following description of two exemplary embodiments shown in the drawings. The drawings use the example of a window to show:
  • 1 shows a corner section of a window with a roller shutter box above it as an overview,
  • 2 is a side view in the direction of the arrow II of FIG. 1,
  • 3 shows a longitudinal section through the drive parallel to the window plane, two arrangements of a first embodiment being shown together,
  • 4 shows a schematic end view in the direction of the viewing apple IV of FIG. 3,
  • Fig. 5 is a Fig. 3 corresponding representation of a drive alternative, and
  • 6 is an end view in the direction of the arrow VI of FIG. 5.

In Fig. 1 ist mit 10 ein Flügel eines Fensters mit Scheibe 11 bezeichnet. 12a beziffert den Rol­ladenpanzer eines in teilweise herabgelassenem Zustand außen vor dem Flügel 10 befindlichen Rol­ladens 12, der innerhalb eines im Raum oberhalb des Fensterdurchbruchs 13 angebrachten Rolladenkastens 14 auf eine nicht dargestellte Wickelwelle aufge­wickelt wird.In Fig. 1, 10 denotes a wing of a window with a pane 11. 12a quantifies the roller shutter curtain of a roller shutter 12 located in front of the wing 10 in a partially lowered state, which is wound onto a winding shaft (not shown) within a roller shutter box 14 attached in the space above the window opening 13.

Der Flügel 10 ist mittel üblicher Scharnierbe­schläge 15 am Blendrahmen 16 angeschlagen. Damit der Flügel 10 um mehr als 90°, vorzugsweise um 180° öffenbar ist, befinden sich die aus dem Rolladen­kasten 14 austretenden Antriebsteile 17 an bzw. vor der seitlichen, zur Mauernische 13 weisenden Stirn­seite 18 des Rolladenkastens 14, der mehr oder weniger weit gegenüber der Wandebene 19 vorsteht. Von den Antriebsteilen 17 zeigen Fig. 1 und 2 sche­matisch ein Antriebswellende 20, welches in einem Wandlager 21 abgefangen ist, sowie eine mit dem Wellenende 20 zu kuppelnde oder fest mit ihm ver­bundene Handkurbel 22.The wing 10 is attached to the frame 16 by means of conventional hinge fittings 15. So that the wing 10 can be opened by more than 90 °, preferably by 180 °, the drive parts 17 emerging from the roller shutter box 14 are located on or in front of the lateral end face 18 of the roller shutter box 14 which faces the wall recess 13 and which is more or less far opposite the wall level 19 protrudes. 1 and 2 schematically show a drive shaft end 20, which is intercepted in a wall bearing 21, and a crank handle 22 to be coupled to the shaft end 20 or fixedly connected to it.

Je nach Tiefe des Fenstersturzes 23 ist das Wandlager 21 mehr oder weniger weit zur Frontwand 24 des Rolladenkastens 14 hin in den Raum hinein angeordnet. In Fig. 2 veranschaulicht der Zeich­nungsteil mit durchgezogenen Linien eine Anordnung bei einem weniger tiefen, mit strichpunktierten Linien bei einem tieferen Mauersturz. Wie die Erfindung diesen unterschiedlichen Erfordernissen Rechnung trägt, wird noch anhand der weiteren Figuren erläutert, die entsprechende schematische Stirnansichten zeigen.Depending on the depth of the lintel 23, the wall bearing 21 is more or less far from the front wall 24 of the roller shutter box 14 arranged in the room. In Fig. 2 the drawing part with solid lines illustrates an arrangement with a less deep, with dash-dotted lines with a deeper fall of the wall. How the invention takes these different requirements into account will be explained with reference to the other figures, which show corresponding schematic end views.

Die gometrische Drehachse der Rolladen-Wickel­welle ist mit 25 bezeichnet, zu der das als Kegel­rad mit nach außen weisender Verzahnung 27 ausge­führte Getrieberad 26 konzentrisch angeordnet ist. Um nun die kraftschlüssige Verbindung vom Gebtrie­berad 28 über die Antriebswelle 29 zum Anschluß-­Wellenende 20 herzustellen, ist die Antriebswelle 29 beim Ausführungsbeispiel nach den Fig. 3 und 4 'doppelt geneigt'.The geometric axis of rotation of the roller shutter winding shaft is denoted by 25, to which the gear wheel 26, designed as a bevel gear with outwardly facing toothing 27, is arranged concentrically. In order to now establish the non-positive connection from the control gear 28 via the drive shaft 29 to the connecting shaft end 20, the drive shaft 29 in the embodiment according to FIGS. 3 and 4 is 'double inclined'.

Denn wie aus Fig 3 ersichtlich ist, steht die Drehachse 30 der Antriebswelle 29 in einer zum herabgelassenen Rolladen 12 bzw. zum geschlossenen Flügel 10 parallelen Ebene schief. Man erreicht dies außer durch Wahl passender Kegelwinkel der miteinander bei 31 kämmenden Kegelräder vor allem durch unkonventionell schief angebrachte Getrie­begehäuseteile 32, die im übrigen derart in die seitliche Wand 18 des Rolladenkastens eingearbeitet sind, daß sie teils innerhalb, teils außerhalb der Wandebene E und somit besonders platzsparend ge­schachtelt untergebracht sind.Because, as can be seen from FIG. 3, the axis of rotation 30 of the drive shaft 29 is inclined in a plane parallel to the lowered roller shutter 12 or to the closed wing 10. This is achieved in addition to the choice of suitable cone angles of the bevel gears meshing with each other at 31, in particular through unconventionally crooked gear housing parts 32, which are otherwise incorporated into the side wall 18 of the roller shutter box in such a way that they are partly inside, partly outside the wall plane E and thus particularly are nested to save space.

Die Antriebswellen-Anordnung 33 des in den Fig. 3 und 4 veranschaulichten Ausführungsbeispiels umfaßt die drei Wellenabschnitte 29, 34 und 20, die jeweils mittels eines Kardangelenks 35 und 36 drehgelenkig miteinander gekoppel sind. Das Zwi­schenstück 34 der Antriebswellen-Anordnung 33 ist mittels einer Kugel 37 in dem eine angepaßte Kugel­pfanne 38 aufweisenden Wandlager 21 toleranzaus­gleichend raumbeweglich gelagert.The drive shaft arrangement 33 of the exemplary embodiment illustrated in FIGS. 3 and 4 comprises the three shaft sections 29, 34 and 20, which are each pivotally coupled to one another by means of a cardan joint 35 and 36. The intermediate piece 34 of the drive shaft arrangement 33 is mounted by means of a ball 37 in the wall bearing 21, which has an adapted ball socket 38, so that it can move in space to compensate for tolerances.

Je nach dem, wie weit der Rolladenkasten 14 gegenüber der jeweiligen Wandfläche 19 (Fig. 2) vorsteht, ist die Antriebswelle 29 auch in der queren Ebene - ggf. beträchtlich - schief gestellt. Fig. 4 veranschaulicht dies mit zwei Alternativen qualitativ anhand der unterschiedlichen Winkel W1 und W2.Depending on how far the roller shutter box 14 protrudes from the respective wall surface 19 (FIG. 2), the drive shaft 29 is also crooked, possibly considerably, in the transverse plane. 4 illustrates this qualitatively with two alternatives based on the different angles W1 and W2.

Der in Fig. 3 eingezeichnte Schnitt A-C veran­schaulicht die hier gegenüber A-B benötigte größere Länge der Antriebswelle 29. Sie kann, um den Be­dürfnissen universell sowie auf einfachste Weise gerecht werden zu können, als Teleskopwelle ausge­führt sein.The section A-C shown in FIG. 3 illustrates the greater length of the drive shaft 29 required here compared to A-B. In order to meet the requirements universally and in the simplest way, it can be designed as a telescopic shaft.

Für einen dichten und optisch ansprechenden Abschluß nach außen sorgt eine Hutze 44, in die das Wandlager 21 eingearbeitet oder der es vorgestzt ist.A scoop 44 into which the wall bearing 21 is incorporated or in which it is provided provides a tight and visually appealing closure to the outside.

Das in Fig. 5 und 6 dargestellte Ausführungs­beispiel verwendet statt einer dreiteiligen Kardan­gelenkwellenanordnung ein dreiteiliges Kegelrad-­Winkelgetriebe mit Antriebswelle 39, Zwischenwelle 40 und Endwelle 41, von denen die Zwischenwelle im Wandlager 21 läuft. Von der 'Schiefstellung' ist hier vor allem die Antriebswelle 39 betroffen, deren bedarfsweise unterschiedliche Neigung (Winkel W1, W2) Fig. 6 schematisch wiedergibt.The exemplary embodiment shown in FIGS. 5 and 6 uses a three-part bevel gear angular gear with drive shaft 39, intermediate shaft instead of a three-part universal joint shaft arrangement 40 and end shaft 41, of which the intermediate shaft runs in the wall bearing 21. The "misalignment" affects above all the drive shaft 39, whose different inclination (angle W1, W2) is shown schematically in FIG. 6.

Das Wellenendstück 41 ist in einem kleinen Lagerbock 42 hinter der Hutze 44 außerhalb der Rolladenkasten-Stirnwand 18 gelagert. Gegenüber der in den Fig. 3 und 4 dargestellten Ausführung be­steht hier noch der Vorteil, daß die Antriebswelle 39 sehr kurz gehalten werden kann.The shaft end piece 41 is mounted in a small bearing block 42 behind the scoop 44 outside the roller shutter box end wall 18. Compared to the embodiment shown in FIGS. 3 and 4, there is also the advantage that the drive shaft 39 can be kept very short.

Der Vollständigkeit halber sei noch erwähnt, daß die nicht dargestellte Rolladen-Wickelwelle mit dem mit 43 bezifferten Anschlußstück drehfest gekuppelt wird, welches vom Getrieberad 26 dreh­antreibbar ist.For the sake of completeness, it should also be mentioned that the roller shutter winding shaft, not shown, is rotatably coupled to the connector numbered 43, which can be driven by the gearwheel 26.
