Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei Zug-Jalousien, welche mit runden Aufzugschnüren α α versehen werden, hat man die stets senkrecht bleibende Lage dieser Schnüre in bekannter Weise dadurch erreicht, dafs man die Walze b in einem Gewindezapfen b1 lagert und dadurch bei jeder Umdrehung eine axiale Verschiebung gleich einer Schnurdicke erzeugt.In the case of roller blinds, which are provided with round elevator cords α α , the position of these cords, which always remains vertical, has been achieved in a known manner by mounting the roller b in a threaded pin b 1 and thereby an axial displacement equal to one with each revolution Line thickness generated.

Soll für den Antrieb solcher Walzen ein flacher Gurt c Verwendung finden, was da wünschenswerth ist, wo der Aufzug vom Innern eines Zimmers bewirkt werden soll, dann steht der geregelten Aufwickelung derselben die axiale Walzenverschiebung schädlich entgegen.If a flat belt c is to be used to drive such rollers, which is desirable where the elevator is to be effected from inside a room, then the controlled winding of the same is detrimentally opposed to the axial displacement of the rollers.

Die aus der Zeichnung ersichtliche Neuerung ermöglicht für diesen Fall die Aufwickelung des in ein und derselben Ebene zugeführten Gurtes c auf die axial fortschreitende Walze b. The innovation shown in the drawing enables the winding of the belt c fed in one and the same plane onto the axially advancing roller b in this case.

Die Walze ist zu diesem Zwecke mit dem konischen Anlauf i»2 versehen, dessen Steigung dem Verhältnifs der Gurtdicke zur Schraubenganghöhe entspricht.For this purpose, the roller is provided with the conical run-up i » 2 , the pitch of which corresponds to the ratio of the belt thickness to the screw pitch.

Der Gurt schliefst sich dann in spiralschraubenförmigen Windungen diesem Anlauf b2 an und findet dadurch sichere Auflage.The belt then joins this run-up b 2 in helical-helical turns and thus finds a secure support.
