Description
Bei der bisher bekannt gewordenen Vorrichtung zur Verhinderung" des Zusammenrollens der Verbindungsschnüre zwischen TeTephonapparaten, insbesondere Tischapparaten, und dem Hörer wurde eine Spiralfeder sozusagen als Rückgrat verwandt, an der die Rippen bzw. Greifer oder Schnurhalter befestigt waren.In the previously known device for preventing "rolling up." the connecting cords between telephone sets, especially desk phones, and a spiral spring was used as the backbone of the listener, so to speak, on which the Ribs or grippers or cord holders were attached.
Die Enden dieser Schnurhalterarme verlaufen von ihrem Anfang bis zu ihrem Ende in gleicher Bogenform und gestatten ebenso leicht das Einbringen als auch das Herausbringen der Schnur in das durch die Halter gebildete röhrenartige Gehäuse. Bei längerem Gebrauch oder durch Ungeschicklichkeit in der Handhabung wird ein Heraustreten der Schnur erfolgen, insbesondere wenn, wie dies häufiger vorkommen dürfte, einzelne Schnurhalterarme ab- oder zerbrechen, was dann leicht ein Heraustreten der Schnur ihrer Länge nach zur Folge hat.The ends of these cord holder arms extend from their beginning to their end in same arch shape and allow just as easily the introduction as well as the removal the cord into the tubular housing formed by the holders. With prolonged use or clumsiness in handling will result in the line coming out, especially if, like this should happen more often, individual cord holder arms break or break, what then easily causes the cord to protrude along its length.
Diesen Übelstand beseitigt die vorliegende Erfindung.The present invention overcomes this drawback.
Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, und zwar zeigt:In the drawing, an embodiment of the invention is shown, namely shows:
Fig. ι eine Stirnansicht mit durch Strichlinien angedeuteter Schnur.
Fig. 2 eine Seitenansicht.Fig. Ι a front view with a line indicated by dashed lines.
Fig. 2 is a side view.
Die Vorrichtung besteht aus einem Feder- 3« drahtgehäuse, das aus nur einem Draht α gewunden ist, derart, daß der an sich bekannte seitliche Einführungsschlitz l· der Telephonschnur c Begrenzungsteile α1 aufweist, die etwas nach innen umgebördelt sind, wie dies insbesondere in der Stirnansicht (Fig. 1) deutlich erkennbar ist.The device consists of a spring wire housing, which is wound from only one wire α , in such a way that the known lateral insertion slot l of the telephone cord c has delimiting parts α 1 which are slightly crimped inwards, as shown in particular in FIG the front view (Fig. 1) can be clearly seen.
Durch diese Anordnung wird ein bequemes Hineindrücken der Schnur c ermöglicht und . die hineingedrückte Schnur gegen unbeabsichtigtes selbsttätiges Heraustreten gesichert.This arrangement enables the cord c to be pushed in easily and. the pressed-in cord is secured against unintentional automatic stepping out.
Um die Schnur aus dem Gehäuse wieder herauszubekommen, muß der Schlitz durch seitliches Abdrängen des Federdrahtes erst genügend erweitert werden. _In order to get the cord out of the housing again, the slot has to go through lateral displacement of the spring wire can only be expanded sufficiently. _
