Gezogene oder stranggepreßte Hohlprofilschiene aus Kunststoff, Drawn or extruded hollow profile rails made of plastic ,
Die Erfindung betrifft eine gezogene oder stranggepreßte Hohlprofilschiene aus Kunststoff. Es ist bekannt, daß aus Kunststoff gefertigte Schienen die Tendenz haben, sich zu verziehen, wenn sie keine große Stärke oder keine entsprechend starken Versteifungsrippen oder -Stege aufweisen. Um relativ teueren Kunststoff einzusparen muß aber versucht werden, Kunststoff-Profilschienen mit möglichst dünner Wandstärke herzustellen.The invention relates to a drawn or extruded one Plastic hollow profile rail. It is known that rails made of plastic have a tendency to warped if they are not very strong or have no correspondingly strong stiffening ribs or webs. In order to save relatively expensive plastic, however, an attempt must be made to use plastic profile rails as far as possible produce thin wall thickness.

Um auch bei dünnwandigen Profilsehienen aus Kunststoff ein Verziehen zu verhindern, ist bereits bekannt, Kunststoffprofilschienen mit einer eingezogenen oder umgossenen Metallarmierung zu versehen. Außerdem ist beispielsweise bei Gardinenschienen aus Kunststoff bekannt geworden, die Kunststoffschiene zur Stabilisierung mit Holzkernen zu versehen.This also applies to thin-walled profile rails made of plastic To prevent warping is already known, plastic profile rails with a retracted or cast To provide metal reinforcement. In addition, it has become known, for example in curtain rails made of plastic, the plastic rail for stabilization with wooden cores to provide.
Die Armierung von Kunststoff-Profilschienen sowohl mit Metall als auch mit Holz ist relativ teuer. Der vorliegenden Erfindung lag nun die Aufgabe zugrunde, speziell gezogene oder stranggepreßte Hohlprofilschienen aus Kunststoff zu schaffen, die trotz geringer Wandstärke eine ausreichende Festigkeit gegen Verziehen aufweisen, so daß sie ohne weiteres beispielsweise als Gardinenschienen verwendet werden können.The reinforcement of plastic profile rails with both Metal as well as wood is relatively expensive. The present invention was now based on the object, specifically To create drawn or extruded hollow profile rails made of plastic, despite the low wall thickness have sufficient resistance to warping so that they can easily be used, for example, as curtain rails can be used.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die allseitig geschlossenen Hohlräume der Schiene mit erhärtetem Kunststoffschaum ausgefüllt werden.This object is achieved according to the invention in that the hollow spaces of the rail, which are closed on all sides, are filled with hardened plastic foam.
In der beiliegenden Zeichnung ist eine einstückig aus Kunststoff gezogene Gardinenschiene 1 im Schnitt dargestellt, die zwei durch jeweils einen Längsschlitz 3 hindurch zugängliche durchgehende Kammern 2 zur Aufnahme der an den Gardinen befestigten Gleitern aufweist. Im übrigen ist die Gardinenschiene 1 mit allseitig ge-In the accompanying drawing, one is made in one piece Drawn plastic curtain rail 1 shown in section, the two each through a longitudinal slot 3 has through accessible through chambers 2 for receiving the gliders attached to the curtains. in the the rest of the curtain rail 1 with all sides

schlossenen durchgehenden Hohlräumen 4 versehen, die alle mit erhärtetem Kunststoffschaum ausgefüllt sind. Diese Kunststoffschaumfüllung verleiht der Gardienenschiene 1 eine ausreichend© Festigkeit gegen Verziehen und ist wesentlich billiger und einfacher während des Ziehens der Hohlprofilschiene oder nachträglich einzubringen, als eine Metall- oder Holzarmierung, die maßgerecht vorgefertigt werden muß« Die Kunststoffschaumfüllung der Hohlräume 4 wird dagegen durch einfaches Aufschäumen erhalten. Als Schaumfüllung kommen Kunststoffe auf der Basis von Polyurethan oder Hart-Polyvin-/SyIchlorid in Frage. Die Kunststoffschaumfüllung hat außerdem den Vorteil, daß mit ihr Hohlprofilschienen mit beliebigen Querschnittsformen versteift werden können, was mit Yersteifungskernen aus Holz oder Metall nicht möglich ist.closed continuous cavities 4, which are all filled with hardened plastic foam. This plastic foam filling gives the curtain rail 1 has sufficient resistance to warping and is much cheaper and easier during the Pulling the hollow profile rail or adding it later, as a metal or wood reinforcement, which is true to size must be prefabricated «The plastic foam filling the cavities 4, however, are obtained by simple foaming. Plastics are used as the foam filling based on polyurethane or hard polyvinyl chloride in question. The plastic foam filling has also the advantage that it can be used to stiffen hollow profile rails with any cross-sectional shape, which is not possible with stiffening cores made of wood or metal.
