Abstract

The arrangement has a linearly movable slider perpendicular to the shutter track surface with a locking bolt and a toothed rod at the actuation end in which a motor-driven toothed wheel (14) engages. A worm wheel (15) mounted coaxially with the toothed wheel is engaged by a worm (16) seated on a drive shaft (17) of an electric motor (18) that crosses the toothed wheel axle perpendicularly. The number of teeth on the worm wheel is a number of times greater than the number of teeth on the toothed wheel.

Description

Die Erfindung betrifft eine Rolladensicherung mit einem senkrecht zur Fläche des Rolladenpanzers linear bewegbaren Schieber mit einem Riegelbolzen und mit einer Zahnstange am Betätigungsende. in die ein motorgetriebenes Zahnrad eingreift.The invention relates to a roller shutter security device with a perpendicular to the surface of the roller shutter curtain linearly movable slide with a locking bolt and with a rack at the actuation end. which engages a motor-driven gear.

Die DE 9401906 U1 beschreibt eine Rolladensicherung der gattungsgemäßen Art. Das Zahnrad sitzt auf der Antriebswelle eines Elektromotors. Die hohe Drehzahl eines kostengünstigen Elektromotors muß untersetzt werden, damit das Zahnrad ein ausreichendes Drehmoment zur Verschiebung der Zahnstange überträgt. Entsprechende Zahnradgetriebe sind sehr aufwendig und kostenträchtig.DE 9401906 U1 describes a roller shutter lock of the generic type. The gearwheel sits on the drive shaft of an electric motor. The high speed of an inexpensive electric motor must be reduced so that the gear has sufficient torque to move the rack transmits. Corresponding gear transmissions are very complex and costly.

Aufgabe der Erfindung ist eine preiswerte und anpassungsfähige Getriebeanordnung.The object of the invention is an inexpensive and adaptable gear arrangement.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß gleichachsig zu dem Zahnrad ein Schneckenrad angeordnet ist, in das eine auf der die Achse des Zahnrades senkrecht kreuzende Antriebswelle eines Elektromotors sitzende Schnecke eingreift.This object is achieved according to the invention in that coaxially with the gear Worm gear is arranged in the one on the perpendicularly crossing the axis of the gear drive shaft of an electric motor engages the worm seated.

Die Erfindung unterscheidet sich insofern vom Stand der Technik, als durch das Schneckenrad und das Zahnrad eine hohe Untersetzung der Motordrehzahl erzielt wird. Da die Antriebwelle des Elektromotors die Achse des Schneckenrades senkrecht kreuzt, kann die Antriebswelle in der dadurch bestimmten Radialebene zur Achse des Schneckenrades, also innerhalb der Ebene des Schneckenrades selbst, in beliebiger Ausrichtung innerhalb des Gehäuses angeordnet werden. Damit können räumliche Gegebenheiten optimal ausgenutzt werden. Das Schneckengetriebe hat selbsthemmende Eigenschaften, so daß die Rolladensicherung vonseiten des Riegelbolzens nicht entsichert werden kann.The invention differs from the prior art in that the worm wheel and the gear provides a high reduction in engine speed. Because the drive shaft of the electric motor the axis of the worm wheel crosses vertically, the drive shaft can in the determined Radial plane to the axis of the worm wheel, i.e. within the plane of the worm wheel itself, can be arranged in any orientation within the housing. This allows spatial Conditions are optimally exploited. The worm gear has self-locking properties, so that the roller shutter cannot be unlocked on the locking bolt side.

Eine hohe Untersetzung und damit Drehmomentanpassung wird dadurch erzielt, daß die Zähnezahl des Schneckenrades mehrfach größer als die Zähnezahl des Zahnrades ist.A high reduction and thus torque adjustment is achieved in that the number of teeth of the worm gear is several times larger than the number of teeth on the gear.

Eine optimale Anpassung der Untersetzung wird dadurch erzielt, daß das Schneckenrad etwa 100 Zähne und das Zahnrad etwa 10 Zähne aufweisen. An optimal adjustment of the reduction is achieved by the worm wheel being about 100 Teeth and the gear have about 10 teeth.

Ein kompakter Getriebaufbau durch ein Doppelzahnrad wird dadurch erzielt, daß das Zahnrad und das Schneckenrad als einstückiges Thermoplastformteil ausgebildet sind.A compact gear structure by a double gear is achieved in that the gear and the worm wheel are designed as a one-piece thermoplastic molded part.

Eine genaue Positionierung des Riegelbolzen wird dadurch sichergestellt. daß der Schieber mit Endschaltern zusammenwirkt.This ensures precise positioning of the locking bolt. that the slider with Limit switches cooperate.

Eine einfache Anpassung an die Einbauverhältnisse erzielt man dadurch, daß der Riegelbolzen in dem Schieber in Längsrichtung verstellbar und festspannbar aufgenommen ist.A simple adaptation to the installation conditions is achieved by the locking bolt in the slider is adjustable in the longitudinal direction and can be tightened.

Eine stabile und genaue Ausrichtung der Rolladensicherung wird dadurch erzielt, daß das Gehäuse der Rolladensicherung an eine Rahmenleiste eines Fensters anschraubbar ist.A stable and precise alignment of the roller shutter lock is achieved in that the housing the roller shutter lock can be screwed onto a frame of a window.

Die Führung des Riegelbolzens wird dadurch optimiert, daß der Riegelbolzen in einer Fuhrungshülse des Gehäuses geführt ist und daß die Führungshülse in einem Durchgang der Rahmenleiste sitzt.The guidance of the locking bolt is optimized in that the locking bolt in a guide sleeve of the housing is guided and that the guide sleeve sits in a passage of the frame bar.

    Ein in dem Gehäuse 1 in Richtung des Doppelpfeils 5 linear geführter Schieber 7 nimmt einen in die Führungshülse 4 und in den Durchgang hineinreichenden Riegelbolzen 6 auf, der mit einem Profilstab des nicht dargestellten Rolladenpanzers sperrend in Eingriff gebracht werden kann. Der Riegelbolzen 6 ist innerhalb des Schiebers 7 verstellbar und mittels einer Schraube 8 oder dergleichen festspannbar, damit eine Anpassung an die Dicke der Rahmenleiste und die Abmessungen der Rolladenführung möglich ist.A linearly guided in the housing 1 in the direction of the double arrow 5 slide 7 takes one in the guide sleeve 4 and locking bolt 6 extending into the passage, with a profile bar of the roller shutter curtain, not shown, can be brought into engagement. The latch bolt 6 is adjustable within the slide 7 and can be tightened by means of a screw 8 or the like, thus an adaptation to the thickness of the frame bar and the dimensions of the roller shutter guide is possible.

    An einem Ansatz 9 des Schiebers 7 ist eine Zahnstange 10 ausgebildet. Ein Profil 11 des Schiebers 7 wirkt mit Endschaltern 12 zusammen. Die Achse eines Doppelzahnrads 13 ist senkrecht zur Gehäuseebene und damit auch senkrecht zur Richtung des Doppelpfeils 5 ausgerichtet. Das Doppelzahnrad 13 hat ein Zahnrad 14 mit kleiner Zähnezahl , z.B. 10 Zähne, und ein Zahnrad 15 mit großer Zähnezahl, z.B. 100 Zähne. Das Zahnrad 15 ist als Schneckenrad mit einer Zylinderschnecke 16 in Eingriff. Die Zylinderschnecke 16 sitzt auf der Antriebswelle 17 eines Elektromotors 18. Die Antriebswelle 17 ist senkrecht zur Achse des Doppelzahnrads 13 in einer Radialebene senkrecht zur dieser Achse also in der Ebene des Schneckenrades 15 und damit auch in der Gehäuseebene ausgerichtet. Bei dem Ausführungsbeispiel der Fig. 1 liegt die Antriebswelle parallel zur Richtung des Doppelpfeils 5.A toothed rack 10 is formed on a shoulder 9 of the slide 7. A profile 11 of the slide 7 interacts with limit switches 12. The axis of a double gear 13 is perpendicular to the plane of the housing and thus also aligned perpendicular to the direction of the double arrow 5. The double gear 13 has a gear 14 with a small number of teeth, e.g. 10 teeth, and a gear 15 with a large number of teeth, e.g. 100 teeth. The gear 15 is in the form of a worm gear with a cylindrical worm 16. The cylindrical screw 16 sits on the drive shaft 17 of an electric motor 18. The drive shaft 17 is vertical to the axis of the double gear 13 in a radial plane perpendicular to this axis in the plane of Worm wheel 15 and thus aligned in the housing plane. In the embodiment of the 1, the drive shaft is parallel to the direction of the double arrow 5.

    Die Antriebswelle 17 kann jedoch eine beliebige Ausrichtung innerhalb der genannten Radialebene haben, vergleiche Fig. 2.However, the drive shaft 17 can have any orientation within the radial plane mentioned have, see Fig. 2nd

    Der Elektromotor 18 ist hochtourig und hat ein kleines Drehmoment. Ein solcher Elektromotor 18 ist recht preiswert verfügbar. Man benötigt kein Untersetzungsgetriebe. Das Schneckengetriebe ist selbsthemmend, so daß der Riegelbolzen in den Endstellungen, insbesondere in der Verriegelungsstellung, gesichert ist. Eine Verschiebung vonseiten des Riegelbolzens und damit eine Aufhebung der Verriegelung ist nicht möglich.The electric motor 18 is high-speed and has a low torque. Such an electric motor 18 is available quite cheaply. You don't need a reduction gear. The worm gear is self-locking, so that the locking bolt in the end positions, especially in the locking position, is secured.
