Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft eine Schnurrolle, insbesondere zur Benutzung an Rollvorhängen, . die mittels Schnur ohne Ende bewegt werden. Diese Rolle besteht zwecks Billigkeit und Leichtigkeit aus einer Scheibe aus gestanztem Blech mit am Umfange abwechselnd nach beiden Seiten gedrückten Zähnen, die im mittleren Teile einen nach innen gerichteten Vorsprung haben.The invention relates to a cord roller, in particular for use on roll-up curtains, . which are moved by a cord without end. This role exists for the purpose of equity and Lightness from a disc of punched sheet metal with alternating around the circumference teeth pressed on both sides, which in the middle part have an inwardly directed protrusion to have.

ίο Die Zeichnung stellt zwei Ausführungsformen der Erfindung dar: ίο The drawing shows two embodiments of the invention:

Fig. ι ist ein Aufriß, Fig. 2 ein senkrechter Schnitt und Fig. 3 eine Teilansicht von oben. Fig. 4 bis 6 zeigen in gleichen Ansichten eine Abänderung.Fig. 1 is an elevation, Fig. 2 is a vertical section and Fig. 3 is a partial view from above. 4 to 6 show a modification in like views.

Die Rolle besteht aus einer starken Blechplatte, deren Umfang durch eine Reihe radialer Spalten in eine Anzahl Zähne 2 geteilt ist, die abwechselnd nach rechts und nach links gebogen werden, wie die Zeichnung zeigt. Jeder Zahn ist in der Mitte eingedrückt (Fig. 3), so daß sich mittlere, nach dem Innern der Schnurscheibe zu vorstehende Rippen bilden. Diese vorspringenden Rippen geben den Zähnen Starrheit, vermehren die Adhäsion der Schnur bei ihrer Betätigung und vermeiden ihre Abnutzung durch die radial stehenden Ränder der Zähne.The roll consists of a strong sheet metal plate, the circumference of which is marked by a number radial column is divided into a number of teeth 2, which alternate to the right and bent to the left as shown in the drawing. Each tooth is indented in the middle (Fig. 3), so that the middle, after the inside of the pulley to protruding Form ribs. These protruding ribs give the teeth rigidity, increase the Adhesion of the cord as it is operated and avoiding its wear by the radially standing edges of the teeth.
