Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die dargestellte Einrichtung Bezweckt, das Aufziehen von Rollläden wie auch das Herablassen zu erleichtern.The purpose of the device shown is the raising of roller shutters as well as lowering them to facilitate.
Es wurde nämlich ein Gegengewicht angeordnet und die Schnur desselben auf einer schneckenförmigen Rolle angebracht. Die Schnur wurde so befestigt, dafs sie sich abgewickelt hat, wenn der Rollladen noch nicht ganz aufgezogen ist; sie 'wickelt sich darum zum Theil in gleicher Richtung mit dem Rollladen auf und hilft somit anfänglich denselben herabziehen, damit es nicht nöthig ist, wie bisher, an den Rollläden ziehen zu müssen.This is because a counterweight was arranged and the cord of the same on one helical roller attached. The cord was fastened so that it would unwind if the roller shutter has not yet been fully opened; it wraps itself around it in part in the same direction as the roller shutter and thus initially helps to pull it down so that it is not necessary, as so far, having to pull on the shutters.
Wird der Rollladen ganz heruntergelassen, so windet sich die Schnur auf den schneckenförmigen Scheibenwindungen auf, so dafs sie, wenn der Rollladen ganz niedergelassen und das ganze Gewicht desselben zu heben ist, auf der gröfsten Schneckenwindung sich befindet und das angebrachte Gewicht g fast das ganze Gewicht des Rollladens, welches nunmehr zur Geltung kommt, ausbalancirt, während beim Wiederaufziehen des Vorhanges sich die Schnur auf der Schneckenscheibe mehr dem Ende der Welle nähert, so dafs, wie sich das Gewicht des herabhängenden Fadens verringert, auch der Zug verringert wird, den das Gegengewicht auf die Welle ausübt, bis der Faden in die in Fig. 3 gezeichnete Stellung kommt, wo dann die Schnur des Gegengewichtes, welches hier in die Endstellung gekommen ist, in entgegengesetzter Weise, wie schon erwähnt, mit dem Laden aufgewunden wird.When the shutter completely lowered, as the cord winds on to the helical wheel turns, so it that if the shutter settled completely and the entire weight thereof is to lift, is located on the greatest of the cochlea and the attached weight g almost the whole weight of the roller shutter, which now comes into its own, is balanced, while when the curtain is drawn up again the cord on the worm disk approaches the end of the shaft, so that, as the weight of the hanging thread is reduced, the tension exerted by the counterweight is also reduced exerts on the shaft until the thread comes into the position shown in Fig. 3, where then the cord of the counterweight, which has come to the end position here, is wound in the opposite way, as already mentioned, with the store.
