Description

Biegsames Elektroinstallationsrohr Die Erfindung betrifft ein biegsames Elektroinstallationsrohr, das am Verlegungsort in passende Längen unterteilt ist und eine Einlage zum Einziehen von Leitungsdrähten besitzt.Flexible electrical conduit The invention relates to a flexible conduit Electrical installation pipe that is divided into suitable lengths at the installation site and has an insert for pulling in lead wires.

Solche Rohre sind an sich bekannt und werden in größeren Längen, z. B. 25, 50 oder 100 m, auf Ringe aufgerollt geliefert. Ihr Vorteil besteht darin, daß sie sich leicht transportieren lassen, mühelos mit den Händen ohne Werkzeuge in jede gewünschte Form gebogen werden können und keine Muffen oder Bogenstücke erforderlich sind, wie dies bei starren Installationsrohren der Fall ist.Such pipes are known per se and are made in greater lengths, e.g. B. 25, 50 or 100 m, delivered rolled up on rings. Their advantage is that they are easy to transport, can easily be bent into any desired shape with the hands without tools and no sleeves or elbows are required, as is the case with rigid installation pipes.

Dabei ist es auch bekannt, innerhalb des Installationsrohres einen Draht oder einen Faden vorzusehen, der es erlaubt, die Leiter in das Innere des Rohres nachzuziehen.It is also known to have one inside the installation pipe Wire or thread to allow the ladder to be inserted into the interior of the Retighten the pipe.

Zur Erleichterung der Handhabung eines solchen Installationsrohres wird nun erfindungsgemäß vorgeschlagen, die Einlage innerhalb des Rohres wellen-, spiral-, zickzack- oder mäanderförmig bzw. in ähnlicher Weise anzuordnen, derart, daß sie nach Abschneiden einer Rohrlänge daraus hervorragt bzw. von beiden Seiten auf eine zum Befestigen der einzuziehenden Drähte bzw. der Zugvorrichtung notwendige Länge ausziehbar ist.To facilitate the handling of such an installation pipe is now proposed according to the invention, the insert within the tube wave, to be arranged in a spiral, zigzag or meander shape or in a similar manner, that it protrudes from it after cutting a length of pipe or from both sides on one necessary for fastening the wires to be drawn in or the pulling device Length is extendable.

Dabei ist es weiterhin zweckmäßig, wenn die Einlage lediglich als Zugorgan zum Nachziehen einer Installationsleitung ausgebildet ist und beispielsweise aus einem Stahldraht von etwa 1 mm Stärke besteht.It is also useful if the deposit is only as Pulling element is designed for tightening an installation line and, for example consists of a steel wire about 1 mm thick.

Es kann weiterhin das Zugorgan mit-einem Überzug zum Schutz gegen Rosten und gegebenenfalls auch mit einem Gleitmittel zwecks besseren Herausziehens versehen sein.The pulling element can still be provided with a cover to protect against Rust and possibly also with a lubricant for the purpose of better extraction be provided.

Dabei besteht der wesentliche Fortschritt in der Gewinnung freier Enden der Einlage durch einfaches Herausziehen der Einlage von beiden Seiten eines Rohrabschnittes her, um auf der einen Seite eine Befestigungsmöglichkeit für das Nachziehen der Installationsleitung und auf der anderen Seite ein genügendes Ende zum Anfassen des Zugorgans zu gewinnen.The main progress here is to obtain freer ones Ends of the liner by simply pulling the liner out from either side of one Pipe section in order to have a fastening option for the Tighten the installation cable and on the other side a sufficient end to get hold of the pulling organ.
