Abstract

The known roller-blind hand-operated drives are actuated by means of belts or gear mechanisms which, on the one hand, are sluggish and, on the other hand, require a special retaining and winding-up device. Both in terms of appearance and from a technical and handling point of view, this is not the best solution since even the retaining and winding-up device has to be mounted on site. The roller-blind motor is an improved roller-blind hand-operated drive, characterised in that, when paying out the roller shutter, a helical spring, which is installed in the hollow profile of the roller-blind roll, stores force which is used for opening or for winding up the roller shutter. The retaining device of the roller shutter is achieved by mounting the roller-blind roll with an automatic return-movement locking means. The roller-blind hand-operated drive is actuated by a non-endless cord which, in contrast to a belt pulley, has two chambers, that is to say one for winding up the cord and one for paying out the cord. The advantage lies in a larger actuating area, with the result that windowsills can be concealed, for example, by flowers or furniture.

Description

Rolladen-MotorRoller shutter motor

Die Erfindung betrifft einen Rolladen-Motor mit automatischen Drehmomentausgleich und Halteeinrichtung gum Rolladenpanger.The invention relates to a roller shutter motor with automatic torque compensation and holding device gum roller shutter bracket.

Es sind Rolladenantriebe bekannt, wo über Qurt- oder Kettenr@den der Rolladenpanger auf - bgw. abgespult wird. Diese Antriebe haben den Nachteil, daß bei schweren $olladenpangern Übersetgungsantriebe benutgt werden, die auf der gesamten Auf- bgw. Abspulhöhe die gleiche Übersetgung haben. Zusätgliche Kosten entstehen durch die Notwendigkeit eines Gurtaufrollers mit Halteeinrichtung, der außerdem noch weitere Kosten durch bauseitige Montage verursacht.There are roller shutter drives known where the Qurt or Kettenr @ the Roller shutter hangers on - bgw. is unwound. These drives have the disadvantage that In the case of heavy roller shutter hangers, transmission drives are used that are on the entire Job bgw. Unwind height have the same gear ratio. Additional costs arise by the need for a belt retractor with a holding device, which also further costs caused by on-site assembly.

Weitere Nachteile bei Rolladen-Fertigbauelementen sind, daß die Getriebe mit Bedienungskurbel gum Auf- Abspulen des Rolladenpanger@ äußerlich ins Auge stechen und kostenaufwendig sind.Further disadvantages of prefabricated roller shutters are that the gears Outwardly catch the eye with the gum operating crank and are costly.

Der Erfindung lag die Aufgabe gugrunde, die aufgeführten Mängel gu beseitigen.The invention was based on the object, the listed shortcomings gu remove.

Die Rolladenwalge 1, die als Hohlprofil ausgebildet ist, hat auf einer Seite im Hohlraum eine Schraubenfeder 2, die feweils auf den rolladenpanger 3 abgestimmt ist. Diese Halteachse 4 wird mit Schlüsselfläche in der Halterung 5 gehalten. An der Schlüsselfläche der Halteachse 4 wird die Vorspannung der Schraubenfeder 2 bei aufgespultem Rolladenpanger 3 eingestellt.The roller shutter roller 1, which is designed as a hollow profile, has on one Side in the cavity a coil spring 2, which feweils matched to the roller shutter 3 is. This holding shaft 4 is held in the holder 5 with a wrench flat. At the preload of the helical spring 2 is applied to the wrench surface of the holding shaft 4 wound roller shutter 3 set.

Beim Abspulen des Rolladenpangers 3 wird in der Schraubenfeder 2 durch die Schwerkraft des Rolladenpangers 3 Energie gespeichert, die bei geschlossenem Rolladenpanger 3 vom Freilauf 6/7/8 gehalten wird.When unwinding the roller shutter 3 is in the coil spring 2 by the gravity of the roller shutter banger 3 energy is stored when it is closed Roller shutter 3 is held by the freewheel 6/7/8.

Beim Aufspulen des Rolladenpangers 3 steht die in der Schraubenfeder 2 gespeicherte Energie gur Vrfüg, so daß die notwendige Drehmomentkraft gum Aufspulen des Rolladenpangers 3 nur noch die Reibungskräfte, nicht aber das Gewicht des Rolladenpangers 3 berüchtigen muß.When winding up the roller shutter 3 is in the coil spring 2 stored energy gur available, so that the necessary torque force gum winding of the roller shutter banger 3 only the frictional forces, but not the weight of the roller shutter banger 3 must be infamous.

Durch diesen Vorteil ist es möglich, daß über eine eingige Gurtscheibe 9 mit Hilfe einer nicht endlosen Schnur 11 nach Fig. 2 der Rolladenpanger 3 auf- und abgespult werden kann.This advantage makes it possible to have a single belt pulley 9 with the help of a non-endless cord 11 according to FIG. 2 of the roller shutter 3 on- and can be unwound.

Die Betätigung kann sinngemäß auch durch Auswechseln der Gurtscheibe über ein Kettenrad mit Endloskette erfolgen. LeerseiteActuation can also be carried out by replacing the belt pulley via a sprocket with an endless chain. Blank page
