Das Auf- und Abrollen der Vorhänge vermittelst dieser in beiliegender Zeichnung dargestellten Vorrichtung geschieht folgendermafsen:The rolling up and unrolling of the curtains is shown in the accompanying drawing Device happens as follows:
Das Holzklötzchen a, Fig. 1 und 2, welches an der einen Seite das Lager b, an der anderen die Röllchen c c besitzt, wird an der Wand oder Fensterbekleidung befestigt und die Rollvorhangstange in der Weise an demselben angebracht, dafs ihre Achse d, Fig. 3, mit dem dreikantigen Theil e in dem Lager b liegt (Fig. 5).The wooden block a, Fig. 1 and 2, which has the bearing b on one side and the rollers cc on the other, is attached to the wall or window covering and the roller curtain rod is attached to it in such a way that its axis d, Fig 3, with the triangular part e in the bearing b (Fig. 5).
Das Lager besteht aus einem Stück Blech mit einem der Stärke der Achse entsprechenden Ausschnitt, welcher konisch zuläuft, infolge dessen sich die Achse festklemmt und die Drehung der Vorhangstange verhindert. Wird der Kopf der Rollvorhangstange aber etwa zweimal mit einer Schnur umwickelt, letztere über die Röllchen c c geführt und beide Enden derselben nach vorheriger Einfügung eines darin beweglichen Griffes vereinigt, so wird durch Ziehen an dem letzteren der dreikantige Theil der Achse aus seinem Lager gehoben, während der cylindrische Theil, welcher sich in einem gewissen Abstand unterhalb des Klötzchens befand, gegen das letztere gehoben wird (Fig. 5).The bearing consists of a piece of sheet metal with a cutout corresponding to the thickness of the axis, which is tapered, as a result of which the axis is clamped and prevents the rotation of the curtain rod. If the head of the roller blind rod but wrapped about twice with a cord, the latter out cc over the rolls and both ends thereof united by prior insertion of a movable therein handle, then by pulling on which the triangular portion of the latter, the axis of its bearing lifted while the cylindrical part, which was at a certain distance below the block, is raised against the latter (Fig. 5).
Zieht man jetzt, nachdem auf diese Weise die starke Reibung, welche der dreikantige Theil in seinem Lager erhielt, aufgehoben ist, an dem einen oder anderen Theil der Schnur, so wird dieselbe der Rollvorhangstange die entsprechende Drehung verleihen und damit ein Auf- und Abrollen des anhängenden Vorhanges bewirken.If one now pulls after the strong friction in this way, which is the triangular Part received in his camp, is kept on one or the other part of the cord, so it will give the roll-up curtain rod the appropriate rotation, and with it cause the hanging curtain to roll up and down.
Hört der Zug an dem Griff auf, so fällt der dreikantige Theil in sein Lager zurück und verhindert die weitere Drehung.If the pull on the handle stops, the triangular part falls back into its bearing and prevents further rotation.
