Description
Die Neuerung betrifft ein Betätigungsgetriebe für einen Rolladenpanzer mit zwischen dem Getriebeabtriebselement und der Wickeltrommel angeordneten Klinkengesperre zum Abkuppeln der Wickeltrommel vom Getriebeabtriebselement am Ende der Absenkbewegung.The innovation concerns an operating gear for a roller shutter curtain with ratchet locking mechanism arranged between the gear output element and the winding drum for uncoupling the winding drum from the gear output element at the end of the lowering movement.
Der Neuerung liegt die Aufgabe zugrunde, ein derartiges Betätigungsgetriebe möglichst kompakt und raumsparend auszubilden. The innovation is based on the task of such an actuating gear to be as compact and space-saving as possible.
Neuerungsgemäß wird diese Aufgabe dadurch gelöst, daß das Getriebeabtriebselement als wellenloses Sperrad ausgebildet ist, welches außer wenigstens einer Innenverzahnung sine Lagerbohrung für einen Klinkenträger enthält, der mit der Wickeltrommer drehfest verbunden ist.According to the innovation, this object is achieved in that the transmission output element is designed as a shaftless ratchet wheel is, which sine except at least one internal toothing Contains bearing bore for a pawl carrier, which is rotatably connected to the winding drum.
In vorteilhafter Ausgestaltung der Erfindung ist der Klinkenträger walzenförmig ausgebildet und mit wenigstens einer radial nach auswärts offenen ümfangsnut versehen, in welcher die Sperrklinken auf die Nutachseparallel durchsetzenden Stiften gelagert sind. Bei einer solchen Ausbildung ist es weiterhin von Vorteil, wenn der Klinkenträger eine zentrale Vierkantbohrung aufweist, in welche ein Vierkantzapfen am Stirnende der Wiekeltrommel eingesteckt ist.In an advantageous embodiment of the invention, the pawl carrier is cylindrical and has at least one radial provided to the outwardly open circumferential groove in which the pawls stored on the groove axis parallel penetrating pins are. With such a design, it is also advantageous if the pawl carrier has a central square bore, in which a square pin at the front end of the rocking drum is plugged in.
Ein Aüsführungsbeispiel d<ar Neuerung wird nachstehend in Verbindung mit der Zeichnung näher erläutert. Es zeigen!An exemplary embodiment of the innovation is linked below explained in more detail with the drawing. Show it!

Das in der Zeichnung gezeigte Betätigungsgetriebe ist ein Schneckengetriebe, dessen Abtriebsglied von einem wellen- losen Schneckenrad 2o gebildet ist, welches an seinen Stirnenden Erweiterungen 29 mit innenverzahnung^ 11o aufweist. The actuating gear shown in the drawing is a worm gear, the output member of which is formed by a shaftless worm wheel 2o which has extensions 29 with internal teeth 11o at its front ends.
Zwischen den Erweiterungen 29 ist das Schneckenrad mit einer Lagerbohrung versehen/ in welcher ein walzenförmiger Klinkenträger 22 gelagert ist« Der Klinkenträger hat eine zentrale Bohrung in der Querschnittsform eines Vielecks wie beispielsweise eines Vierkants, in die der zapfenförmige Wellenstumpf 21 am Ende einer Wickeltrommel 211, auf welcher der (nicht gezeigte) Kolladenpanzer aufgewickelt wird, eingesetzt ist.Between the extensions 29, the worm wheel is with a Provided bearing bore / in which a roller-shaped pawl carrier 22 is mounted «The pawl carrier has a central Bore in the cross-sectional shape of a polygon, such as a square, into which the peg-shaped stub shaft 21 at the end of a winding drum 211 on which the (not shown) collade armor is wound up, is used.
Der walzenförmige Klinkenträger 22 ist ferner mit zwei den Erweiterungen 29 das Schneckenrades 2o gegenüberliegenden Ringnuten 25 versehen, in denen an achsparallelen Stiften angelenkte Sperrkli.nken 24 (je drei in jeder Ringnut 25) gelagert sind. Die Stifte 23 bestimmen den Schwenkbereich der Sper'klinken 24.The cylindrical pawl carrier 22 is also with two of the extensions 29 of the worm wheel 2o opposite Provided annular grooves 25 in which locking pawls 24 (three in each annular groove 25) articulated on axially parallel pins are. The pins 23 determine the pivoting range of the locking pawls 24
Obwohl das dargestellt Ausführungsbeispiel an beiden Enden des Schneckenrades 2o je ein solches Klinkengesperre enthält, kann auch nur ein Klinkengesperre an einem Ende vorgesehen sein. Der walzenförmige Klinkenträger 22 befindet sich, wie ersichtlich, innerhalb des Getriebegehäuses 26, welche das Schneckengetriebe mit dem Schneckenrad 2o und der Schnecke 27 umschließt.Although the illustrated embodiment contains such a ratchet lock at both ends of the worm wheel 2o, can also only one ratchet lock can be provided at one end. The cylindrical pawl carrier 22 is, as can be seen, inside the gear housing 26, which encloses the worm gear with the worm wheel 2o and the worm 27.
Die Anzahl der Sperrklinken 24 und der Zähne 21o ist vorzugsweise verschieden, so daß jeweils nur eine Sperrklinke oder, bei entsprechender Anzahl von Sperrklinken, ein Klinkenpaar ausgeschwenkt und in Eingriff mit einem einzigen Zahn bzw. einem Zähnepaar gebracht werde kann.The number of pawls 24 and the teeth 21o is preferably different, so that only one pawl or, with a corresponding Number of pawls, a pair of pawls swung out and brought into engagement with a single tooth or a pair of teeth will can.
Das gezeigte Betätigungsgetriebe läßt sich sowohl für links~ wickelnde als auch für rechtswickelnde Rolläden verwenden,wo-The operating gear shown can be used for both left ~ Use winding as well as right-winding roller shutters, where-
zu es nur erforderlich ist, die Sperrklinken 24 im walzenförmigen lUinkenträger 22 umzusetzen. Das Betätigungsgetriebe läßt sich deshalb an belisbigen Enden der Wickeltrommel anbringen.to it is only necessary to implement the pawls 24 in the cylindrical link carrier 22. The operating gear can therefore attach to any ends of the winding drum.
