Description

Technical area

The invention relates to a cord guide of an automatic retractor for curtains, wherein the clamping plates of the automatic retractor at the openings for the cords next to the connecting pins each have a hinge hole and in the hinge holes the ends of the arcuate line guide elements are inserted, each forming a confining space when the arcuate line guide elements abut the connecting pins, wherein the cords are guided by the boundary spaces of the arcuate line guide elements, whereby the range of movement of the cords is limited, so that a blockage of the cords is avoided.

Object of the invention

• 1. da die bogenförmigen Schnurführungselemente an den Klemmplatten angelenkt sind, sind sie beweglich und können zu den Verbindungsstiften gedreht werden und bilden somit jeweils einen Begrenzungsraum, wobei die Schnüre durch die Begrenzungsräume geführt sind, wodurch wenn beim Anheben oder Absenken des Vorhangstoffs die Schnüre schnell eingerollt oder ausgerollt werden, der Bewegungsbereich der Schnüre durch die Begrenzungsräume begrenzt wird, so dass ein Eintritt der Schnüre in den Spalt der Zahnräder verhindert wird, weshalb eine Blockierung der Schnüre vermieden wird;
• 2. die Verbindungsstifte sind jeweils von einer Hülse umschlossen, damit der Kontakt der Schnüre und der Verbindungsstifte verbessert wird; die beiden Enden der bogenförmigen Schnurführungselemente sind an den beiden Klemmplatten angelenkt, wodurch die bogenförmigen Schnurführungselemente in den Raum zwischen den beiden Klemmplatten gedreht werden können, so dass eine Verklemmung der Schnüre vermieden wird.

The invention has for its object to provide a line guide of an automatic retractor for curtains, wherein the clamping plates of the automatic retractor have at the openings for the cords in addition to the connecting pins arcuate line guide elements which are hinged to the clamping plates and each form a boundary space with the connecting pins through which the cord is guided. Therefore, the invention has the following advantages:

• 1. Since the arcuate line guide elements are hinged to the clamping plates, they are movable and can be rotated to the connecting pins and thus each form a confining space, the cords are guided through the confining spaces, which when quickly rolled up when lifting or lowering the curtain fabric or are rolled out, the range of movement of the cords is limited by the boundary spaces, so that entry of the cords is prevented in the gap of the gears, and therefore blocking of the cords is avoided;
• 2. The connecting pins are each enclosed by a sleeve, so that the contact of the cords and the connecting pins is improved; the two ends of the arcuate line guide elements are hinged to the two clamping plates, whereby the arcuate line guide elements can be rotated in the space between the two clamping plates, so that a jamming of the cords is avoided.

embodiments

Further details, features and advantages of the invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings.

The invention relates to a cord guide of an automatic retractor for curtain, wherein the clamping plates 2 of the automatic retractor 10 at the openings for the cords 1 next to the connecting pins 21 one joint hole each 22 exhibit ( 1 ). In the joint holes 22 become the ends 31 the arcuate line guide elements 3 plugged, which have an Ω-shape.

As a result, the arcuate line guide elements 3 movable between the two clamping plates 2 attached, can to the connecting pins 21 are rotated and thus each form a bounding space 32 (the bounding space 32 is through the out of the connecting pin 21 Outstanding space defined when the arcuate line guide element 3 at the connecting pin 21 applied). The strings 1 be through the bounding spaces 32 led and are from the connecting pins 21 and the string guide elements 3 limited ( 2 ).

In use is the automatic reel-up 10 in the top rail 201 of the curtain 20 attached. The automatic reel-up 10 has two rewind wheels 101 on that through two gears 102 engage each other. On the top of the Aufrollräder 101 is an S-shaped coil spring 103 arranged. To the Aufrollräder 101 become the cords 1 wrapped in the opposite direction. The upper and lower clamping plate 2 attach the rolling wheels and are through the connecting pins 21 connected with each other. The strings 1 be through the bounding spaces 32 passing through the connecting pins 21 at the openings of the automatic retractor 10 and the arcuate line guide elements 3 are formed, guided and run through the curtain fabric 202 (or curtain disks) to pull the curtain ( 3 ). When lifting or lowering the curtain fabric 202 (or curtain discs) become the cords 1 quickly rolled up or rolled out, reducing the range of motion of the cords 1 through the bounding spaces 32 is limited, so that the vibration or fluctuation of the cords 1 is reduced ( 4 and 5 , where in 5 several Aufrollräder are provided). This can cause an entry of the strings 1 in the gap of the gears 102 be prevented, allowing a blockage of the cords 1 is avoided.

The connecting pins 21 can each be from a sleeve 211 be enclosed, thus the contact of the cords 1 and the connecting pins 21 is improved ( 6 ) to the guiding effect for the cords 1 to increase.

The two ends 31 the arcuate line guide elements 3 are on the two clamping plates 2 hinged, causing the arcuate line guide elements 3 in the space between the two clamping plates 2 can be rotated so that the range of movement of the cords 1 is reduced (if the space between the two clamping plates 2 for the Aufrollräder 101 is increased, the winding length of the cords 1 Although enlarged, the range of movement of the cords becomes 1 but also enlarged). Therefore, a jamming of the cords 1 effectively avoided.
