BESCHREIBUNGDESCRIPTION Die vorliegende Erfindung bezieht sich auf einen Antrieb für die Aufzugswelle eines Stores oder Rolladens mit einem mittels eines Stranges antreibbaren, in einem ortsfesten anzuordnenden Gehäuse drehbar gelagerten Rad, das getrieblich mit einem drehfest auf der Aufzugswelle aufsetzbaren Mitnehmer verbunden ist, wobei eine an einer gehäusefesten Zylinderfläche reibende, koaxiale, den Mitnehmer umgebende Schraubenfederbremse ein Verdrehen des Mitnehmers relativ zum Rad verhindert und wobei weiter ein mit dem Rad drehendes Organ in den Mitnehmer eingreift und beim Drehen des Rades die Schraubenfederbremse löst.The present invention relates to a drive for the winding shaft of a blind or roller shutter with a wheel that can be driven by means of a strand and is rotatably mounted in a stationary housing to be arranged frictional, coaxial coil spring brake surrounding the carrier prevents rotation of the carrier relative to the wheel, and further wherein a member rotating with the wheel engages the carrier and releases the coil spring brake as the wheel rotates. Ein Antrieb dieser Art ist aus der DE-OS 3 211 506 bekannt. Er erlaubt eine äusserst schmale Bauweise, was bei der Montage von Rollos, Store, Rolladen und dgl. erwünscht ist. Er besitzt indessen den Nachteil, dass die mittels dem Strang aufzubringende Aufziehkraft bei den üblichen Durchmessern des Rades vergleichsweise gross ist. Der Durchmesser des Rades kann zur Erzielung eines günstigeren Übersetzungsverhältnisses nicht beliebig vergrössert werden, weshalb sich dieser Antrieb für schwere Sonnenschutzeinrichtungen, wie Store und Rolladen, nicht eignet.A drive of this type is known from DE-OS 3,211,506. It allows an extremely narrow construction, which is desirable when installing roller blinds, blinds, roller shutters and the like. However, it has the disadvantage that the winding force to be applied by means of the strand is comparatively large given the usual diameters of the wheel. The diameter of the wheel cannot be increased at will to achieve a more favorable transmission ratio, which is why this drive is not suitable for heavy sun protection devices such as blinds and roller shutters. Die Erfindung stellt sich daher die Aufgabe, einen Antrieb der erwähnten Art bei weitgehender Wahrung der raumsparenden Ausführung, derart zu verbessern, dass die Aufziehkraft geringer und der Antrieb daher für die Store und Rolladen verwendbar ist.The invention therefore sets itself the task of improving a drive of the type mentioned while largely maintaining the space-saving design in such a way that the opening force is lower and the drive can therefore be used for the blinds and roller shutters. Erfindungsgemäss wird diese Aufgabe gelöst durch die kennzeichnenden Merkmale des Anspruchs 1.According to the invention, this object is achieved by the characterizing features of claim 1. Anhand der beiliegenden schematischen Zeichnung wird die Erfindung beispielsweise erläutert. Es zeigen:The invention is explained by way of example on the basis of the attached schematic drawing. Show it: Fig. 1 einen Schnitt längs der Linie I-I in Fig. 2,Fig. 1 shows a section along the line I-I in Fig. 2, Fig. 2 einen Schnitt längs der Linie II-II in Fig. 1 undFig. 2 shows a section along the line II-II in Fig. 1 and Fig. 3 einen Schnitt längs der Linie III-III in Fig. 2.Fig. 3 shows a section along the line III-III in Fig. 2. Das Ende einer Aufzugswelle 1 eines Stores oder Rolladens ist drehbar in einem Antriebsgehäuse 2 gelagert. Das Gehäuse 2 weist einen Deckel 3 mit einem nach innen weisenden Lagerauge 4 auf, das mit einem Aussenzahnkranz 5 versehen ist.The end of an elevator shaft 1 of a blind or roller shutter is rotatably mounted in a drive housing 2 . The housing 2 has a cover 3 with a bearing eye 4 pointing inwards, which is provided with an outer ring gear 5 . Der Deckel 3 ist fest mit dem Gehäusekörper 6 verbunden. Im Gehäuse 2 ist ein Kugelkettenrad 7 drehbar gelagert, das als Ring mit einem Innenzahnkranz 8 ausgebildet ist. Innerhalb des Kugelkettenrades 7 ist axial zur Aufzugswelle 1 ein scheibenförmiges Organ 9 angeordnet, welches mindestens eines, vorzugsweise drei Planetenritzel 10 trägt, die daran drehbar gelagert sind. Die Planetenritzel 10 kämmen einerseits mit dem Aussenzahnkranz 5 und anderseits mit dem Innenzahnkranz 8. Wird das Kugelkettenrad 7 gedreht,The cover 3 is firmly connected to the housing body 6 . A ball chain wheel 7 , which is designed as a ring with an internal ring gear 8 , is rotatably mounted in the housing 2 . Inside the ball chain wheel 7, a disc-shaped member 9 is arranged axially to the elevator shaft 1, which carries at least one, preferably three planet pinions 10, which are rotatably mounted thereon. The planet pinions 10 mesh with the outer ring gear 5 on the one hand and with the inner ring gear 8 on the other. If the ball chain wheel 7 is rotated, laufen die Planetenritzel 10 auf dem Aussenzahnkranz 5 ab und drehen das Organ 9 mit kleinerer Umfangsgeschwindigkeit als das Kugelkettenrad 7 mit. Das Untersetzungsver-hältnis beträgt in etwa 1:1.8. In das Gehäuse 9 ist weiter eine Bremsbüchse 11 fest eingesetzt, die eine zylindrische Innenfläche bildet. In die Bremsbüchse 11 axial eingesetzt ist eine Schraubenbremsfeder 12, deren Enden 13 nach innen abgewinkelt sind. Axial in die Schraubenfeder 12 ist weiter ein Mitnehmer 14 eingesetzt, der eine nach innen vorspringende Rippe 15 aufweist, die in eine Längsnut 16 der Aufzugswelle 1 eingreift. Der Mitnehmer 14 ist daher mit der Aufzugswelle 1 drehfest verbunden. Die Enden 13 der Schraubenfeder 12 liegen zwischen den Enden des im Querschnitt ringsegment-förmigen Mitnehmers 14. Zwischen die beiden Enden 13 greift ein Arm 17 des scheibenförmigen Organs 9 und liegt im Drehweg des Mitnehmers 14.the planetary pinion 10 runs on the external ring gear 5 and rotates the organ 9 with a lower peripheral speed than the ball chain wheel 7 . The reduction ratio is approximately 1:1.8. In the housing 9, a brake sleeve 11 is also firmly inserted, which forms a cylindrical inner surface. Inserted axially into the brake sleeve 11 is a helical brake spring 12 whose ends 13 are angled inwards. A driver 14 is also inserted axially into the helical spring 12 and has an inwardly projecting rib 15 which engages in a longitudinal groove 16 of the winding stem 1 . The driver 14 is therefore non-rotatably connected to the elevator shaft 1 . The ends 13 of the helical spring 12 lie between the ends of the driver 14, which has the shape of a ring segment in cross-section. An arm 17 of the disc-shaped element 9 grips between the two ends 13 and lies in the rotational path of the driver 14. Bei stillstehendem Kugelkettenrad 7 erzeugt ein auf die Auszugswelle 1 wirkender Lamellenpanzer ein Drehmoment, das die Aufzugswelle 1 und den Mitnehmer 14 drehen will. Dadurch kommt der Mitnehmer 14 mit einem der Federenden 13 in Anschlag und weitet die Schraubenfeder 12 derart aus, dass diese gegen die Bremsbüchse 11 drückt und die Aufzugswelle 1 bremst. Wird das Kugelkettenrad 7 gedreht, dreht sich das Organ 9 mit und der Arm 17 kommt mit einem der Federenden 13 in Anschlag, lockert die Bremse und trifft dann auf den Mitnehmer 14 und dreht nun die Aufzugswelle 1 mit. Sobald das Drehen des Kugelkettenrades 7 unterbrochen wird, drückt der Mitnehmer wieder auf eines der Federenden 13 und verhindert eine Drehung der Aufzugswelle 1 relativ zum Gehäuse 2.When the ball chain wheel 7 is stationary, a lamella armor acting on the pull-out shaft 1 generates a torque that intends to rotate the winding shaft 1 and the driver 14 . As a result, the driver 14 comes into contact with one of the spring ends 13 and expands the helical spring 12 in such a way that it presses against the brake sleeve 11 and brakes the winding stem 1 . If the ball chain wheel 7 is rotated, the organ 9 rotates with it and the arm 17 comes into contact with one of the spring ends 13, loosens the brake and then hits the driver 14 and the winding shaft 1 now rotates with it. As soon as the rotation of the ball chain wheel 7 is interrupted, the driver presses on one of the spring ends 13 again and prevents the winding stem 1 from rotating relative to the housing 2. 22 ss 1010 1515 2020 2525 3030 3535 4040 4545 5050 66 1 Blatt Zeichnungen1 sheet of drawings
