KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft eine SchnurklemmeThe invention relates to a cord clamp
der bekannten Art, bei denen die Schnur oder der Gurt zwischen einer festen Wand und einer Rolle gleitet und durch einen Exzenterhebel festgeklemmt wird.of the known type in which the cord or strap is between a solid wall and a roller and is clamped by an eccentric lever.
Das Neue wird darin gesehen, daß der Exzenterhebel, die Rolle teilweise einhüllend, derart auf der Rollenachse gelagert ist, daß er beim Loslassen der Schnur o. dgl. durch ίο sein Eigengewicht in die Klemmstellung übergeht. What is new is seen in the fact that the eccentric lever, partially enveloping the roller, is mounted on the roller axis in such a way that when you let go of the cord or the like ίο its own weight passes into the clamping position.
Die Erfindung ist auf der Zeichnung dargestellt, und zwar bedeutetThe invention is shown in the drawing, namely means
Fig. ι eine Seitenansicht der Schnurklemme, Fig. Ι a side view of the cord clamp,
Fig. 2 eine Vorderansicht.Fig. 2 is a front view.
Die Schnurrolle c ist in einem Gehäuse a gelagert, das in bekannter Weise schwenkbar
an einer Wandplatte angeordnet ist.
Der mit einem Handgriff e versehene Klemmhebel d ist gleichachsig mit der Schnurrolle
c gelagert und hüllt, wie aus der Zeichnung ersichtlich, die Rolle c teilweise ein.
Sein äußerer Umfang ist gegen den Handgriff zu allmählich' verdickt, so daß er einen
Exzenterhebel darstellt. Durch diese ungleiche Massenverteilung wird im Verein mit
dem Gewicht des Handgriffes e erreicht, daß sich der Hebel stets in der Richtung des
Pfeiles der Fig. 1 zu senken sucht.The line roller c is mounted in a housing a which is pivotably arranged in a known manner on a wall plate.
The clamping lever d, which is provided with a handle e , is mounted coaxially with the cord roller c and, as can be seen from the drawing, partially envelops the roller c. Its outer circumference is too gradually 'thickened towards the handle, so that it represents an eccentric lever. This uneven distribution of mass, in conjunction with the weight of the handle e , ensures that the lever always seeks to lower itself in the direction of the arrow in FIG.
Die Wirkung ist folgende:The effect is as follows:
Wird an der Schnur o. dgl. gezogen, so wird durch die Reibung der Exzenterhebel entgegen der Pfeilrichtung in Fig. ι gedreht und dadurch der Umfang der Rolle c freigelegt, so daß die Schnur nunmehr der Rolle c anliegt und sie in Umdrehung versetzt.O is on the cord. Like. Withdrawn, the eccentric lever is rotated in the arrow direction in Fig. Ι by the friction and thereby the circumference of the roll c exposed so that the cord now abuts the roll c and set in rotation.
Hierdurch wird ein Scheuern der Schnur vermieden.This prevents the line from chafing.
Läßt man die Schnur los, so dreht sich der Hebel in seine frühere Lage und klemmt die Schnur zwischen Gehäusewand und seinem keilförmigen Umfang fest. Unter Umständen kann diese Klemmwirkung noch durch Druck auf den Handgriff e vergrößert werden.If you let go of the cord, the lever rotates into its previous position and clamps the cord between the housing wall and its wedge-shaped circumference. Under certain circumstances, this clamping effect can be increased by pressing the handle e .
Beim Niederlassen des Vorhanges o. dgl. ist es erforderlich, den Hebel von Hand so lange außer Eingriff zu bringen, bis der Vorhang die gewünschte Stellung erreicht hat.When lowering the curtain or the like, it is necessary to move the lever by hand long to disengage until the curtain has reached the desired position.
