Description
Die Erfindung betrifft Rohrverbinder gemäß dem Oberbegriff des Anspruches 1.The invention relates to pipe connectors according to the preamble of
Rohrverbinder sind aus der Möbelindustrie in verschiedensten Ausführungsformen bekannt. Zum Einen gibt es kugelförmige Eckverbinder, die orthogonal zueinander angeordnete Bohrungen aufweisen. In den daran angeschlossenen Rohren befindet sich dann ein Gewinde. Durch diese Eckverbinder werden dann Schrauben hindurch geführt und in die Gewinde in den Rohren eingeschraubt, so dass dann eine starre Rohrverbindung entsteht. Da die Schrauben sehr fest angezogen sein müssen und daher auch eine hohe Eigen-Festigkeit benötigen, ist diese Art der Verbindung eine aufwendige und auch teure Lösung.Pipe connectors are known from the furniture industry in various embodiments. On the one hand there are spherical corner connectors, which have orthogonal to each other arranged holes. There is a thread in the connected pipes. Through this corner connectors then screws are passed through and screwed into the threads in the pipes, so that then creates a rigid pipe connection. Since the screws must be very tight and therefore require a high intrinsic strength, this type of connection is a complex and expensive solution.
Eine andere Ausgestaltung vom Stand der Technik ist in der Schrift
In der Schrift
Es ist deshalb Aufgabe der Erfindung, einen Rohrverbinder zu finden, der die Nachteile aus dem Stand der Technik zumindest minimiert.It is therefore an object of the invention to find a pipe connector which minimizes the disadvantages of the prior art at least.
Die Aufgabe wird durch den kennzeichnenden Teil des Anspruches gelöst. Der Erfinder hat erkannt, dass ein Rohrverbinder aus Druckguss zum Einen eine starre Verbindung ermöglicht und zum Anderen auch kostengünstig hergestellt werden kann. Hierbei ist besonders der Werkstoff G-ZnAl4Cu1 vorteilhaft. Aber auch Werkstoffe mit einer einem Aluminiumgehalt von 3 bis 5 Prozent und einem Kupfergehalt von 0,5 bis 2 Prozent sind geeignet.The object is solved by the characterizing part of the claim. The inventor has recognized that a pipe connector made of diecasting on the one hand allows a rigid connection and on the other hand can be produced inexpensively. In this case, the material G-ZnAl4Cu1 is particularly advantageous. But also materials with an aluminum content of 3 to 5 percent and a copper content of 0.5 to 2 percent are suitable.
In einer ersten Ausgestaltung der Rohrverbinder mit den Rohren greifen Anschlussstellen des Rohrverbinders von außen auf das Rohr. Um ein Herausrutschen der Rohre aus dem Rohrverbinder zu verhindern, können Stifte oder Schrauben angeordnet sein, die eine axiale Sicherung vornehmen.In a first embodiment of the pipe connector with the pipes grab connection points of the pipe connector from the outside to the pipe. To prevent slipping out of the pipes from the pipe connector, pins or screws can be arranged, which make an axial securing.
In einer besonders vorteilhaften Ausgestaltung der Erfindung sind die Anschlussstellen des Rohrverbinders als Zapfen ausgebildet. Diese greifen in das Innere des Rohres hinein.In a particularly advantageous embodiment of the invention, the connection points of the pipe connector are designed as pins. These reach into the interior of the pipe.
Damit die Fügekräfte zwischen Rohrverbinder und Rohr nicht zu groß werden, weist dieser Zapfen nicht zwangsläufig die gleiche Kontur wie die Rohrinnenseite auf. Um die Fügekräfte gering zu halten müssten die Fertigungstoleranzen sehr genau aufeinander abgestimmt sein. Deshalb ist es vorteilhaft, wenn der Zapfen an seiner Oberfläche ein Vielkantprofil aufweist. Bei einem runden Rohr kann dieses Vielkantprofil in der Weise geschaffen werden, indem der – bei diesem Beispiel runde – Zapfen mit Abflachungen versehen ist. Werden aber nur zwei, sich gegenüberliegende, Abflachungen angebracht, so sind die Fügekräfte immer noch relativ hoch. Besser ist es daher, wenn mindestens drei oder sogar vier Abflachungen am Zapfen angeordnet sind.So that the joining forces between pipe connector and pipe are not too large, this pin does not necessarily have the same contour as the inside of the pipe. In order to keep the joining forces low, the manufacturing tolerances would have to be coordinated very precisely with one another. Therefore, it is advantageous if the pin has a polygonal profile on its surface. In a round tube of this polygonal profile can be created in such a way by the - in this example round - pin is provided with flats. But if only two, opposing, flattening appropriate, the joining forces are still relatively high. It is therefore better if at least three or even four flats are arranged on the pin.
