Description
Die Erfindung betrifft ein schwalbenschwanzartiges Verbindungselement aus einem Grundkörper, welcher zueinander verjüngt ausgebildete Elemente aufweist.The invention relates to a dovetail Connecting element made of a base body which is tapered to one another Has elements.
Derartige schwalbenschwanzartige Verbindungselemente sind in vielfältiger Form und Ausführung bereits im Markt bekannt und dienen beispielsweise zum Verbinden zweier Profilelemente eines Fensterflügels, eines Fensterrahmens, eines Türrahmens od. dgl..Such dovetail-like Fasteners are already in various forms and designs known in the market and serve, for example, to connect two Profile elements of a window sash, one Window frame, a door frame or the like ..
Diese werden in Holz, Kunststoff oder Metall hergestellt. Nachteilig bei diesen Materialien ist, dass Holz häufig aufquillt oder einer schnelleren Verrottung unterliegt. Zudem wird das schwalbenschwanzartige Verbindungselement aus Holz zumeist in einer anderen Faserrichtung als die Profilelemente selbst eingebaut und sind daher schwer nachzubearbeiten bzw. auch nicht einfach überzulackieren, da diese Stellen sichtbar sind.These are made of wood, plastic or made of metal. The disadvantage of these materials is that wood often swells or is subject to faster rotting. In addition, the dovetail-like connecting element made of wood mostly in a different fiber direction than the profile elements themselves installed and are therefore difficult to rework or not easy to repaint, because these places are visible.
Die schwalbenschwanzartigen Verbindungselemente aus Kunststoff lassen sich zwar gut verarbeiten, jedoch sind gewisse Werkzeuge, insbesondere Schleifwerkzeuge hierdurch beeinträchtigt, wenn insbesondere die aus Kunststoff hergestellte Schwalbe in Holzprofile eingesetzt wird.The dovetail-like fasteners plastic can be processed well, but there are certain Tools, especially grinding tools, are affected by this, if in particular the swallow made of plastic in wooden profiles is used.
Auch ein Überlackieren des schwalbenschwanzartigen Verbindungselementes aus Kunststoff ist nicht immer ohne weiteres möglich, da die Farbe oftmals auf diesem Kunststoff nicht haftet. Ähnliches gilt bei der Ausführung des schwalbenschwanzartigen Verbindungselementes aus Metall, wobei insbesondere die Werkzeuge zum Bearbeiten der beispielsweise aus Holz ausgebildeten Profilelemente einem gewissen unerwünschten Verschleiss oder sogar Beschädigungen unterliegen.Also painting over the dovetail-like Connecting element made of plastic is not always easy possible, because the color often does not adhere to this plastic. something similar applies to the execution of the dovetail-like connecting element made of metal, wherein especially the tools for editing, for example Wood-trained profile elements a certain undesirable Wear or even damage subject.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein schwalbenschwanzartiges Verbindungselement der eingangs genannten Art zu schaffen, welches die genannten Nachteile beseitigt und mit welchem auf einfache und kostengünstige Weise ein Nachbearbeiten, insbesondere in eingesetztem Zustand möglich ist. Zudem soll das schwalbenschwanzartige Verbindungselement leicht zu recyclen und kostengünstig herzustellen sein. Ausserdem soll es hohe Zugkräfte aufnehmen können.The present invention lies hence the task of a dovetail-like connecting element to create the type mentioned, which has the disadvantages mentioned eliminated and with which in a simple and inexpensive way reworking is possible, especially when inserted. In addition, the dovetail-like connecting element should be light to recycle and inexpensive to be manufactured. In addition, it should be able to absorb high tensile forces.
Zur Lösung dieser Aufgabe führt, dass der Grundkörper aus zerkleinerten Holzfasern, insbesondere Holzmehl und einem Binder, insbesondere einem Harz zusammengesetzt ist.The solution to this task is that the basic body made from shredded wood fibers, especially wood flour and a binder, is composed in particular of a resin.
Bei der vorliegenden Erfindung hat sich als besonders vorteilhaft erwiesen, das schwalbenschwanzartige Verbindungselement, insbesondere dessen Grundkörper aus einem Gemisch aus Holzfasern, insbesondere Holzmehl mit Binder, insbesondere zumindest einem Harz herzustellen, wobei ggf. unter Temperatur und Druck das Gemisch dieser Materialien in einer Form zum schwalbenschwanzartigen Verbindungselement hergestellt werden kann. Dabei kann das Gemisch aus Holzfasern und Binder beispielsweise in flüssiger oder sogar fester granulierter Form vorliegen. Durch entsprechendes Erhitzen lässt sich das Granulat in entsprechende Formen zum Herstellen des Grundkörpers einspritzen oder extrudieren. Hierauf sei die vorliegende Erfindung nicht beschränkt.In the present invention proved to be particularly advantageous, the dovetail-like connecting element, especially its main body from a mixture of wood fibers, in particular wood flour with binder, in particular to produce at least one resin, optionally under Temperature and pressure the mixture of these materials in one mold be made to the dovetail-like connecting element can. The mixture of wood fibers and binder can for example in liquid or even solid granular form. By doing so Can be heated inject the granules into appropriate molds to manufacture the base body or extrude. The present invention is not limited to this.
Auch soll im Rahmen der vorliegenden Erfindung liegen, dass beispielsweise die Holzfasern in homogenen oder unterschiedlichen Korngrössen mit zumindest einem Binder, insbesondere einem Naturharz vermischt werden, um den Grundkörper des schwalbenschwanzartigen Verbindungselementes herzustellen. Hierauf sei die Erfindung nicht beschränkt. Hierdurch entsteht ein schwalbenschwanzartiges Verbindungselement aus einem Kompositwerkstoff, welcher viele Vorteile aufweist. Dieser lässt sich mittels herkömmlichen Werkzeugmaschinen auch in eingebauten Fensterprofilen oder Rahmenprofilen gut bearbeiten. Dieser Werkstoff bzw. das schwalbenschwanzartige Verbindungselement lässt sich leicht fräsen, sägen, lasern, schleifen und insbesondere auch gut lackieren. Dabei weist es eine äusserst hohe Zugfestigkeit auf und ist verrottbar, ohne dass eine Materialtrennung, beispielsweise eines Fensterprofiles vorgenommen werden muss.Also intended to be part of the present Invention lie that, for example, the wood fibers in homogeneous or different grain sizes mixed with at least one binder, especially a natural resin be the basic body to produce the dovetail-like connecting element. hereupon the invention is not restricted. This creates a dovetail-like connecting element made of a composite material, which has many advantages. This let yourself using conventional machine tools Also work well in built-in window profiles or frame profiles. This material or the dovetail-like connecting element let yourself easy milling, sawing, laser, sand and in particular also paint well. It points it is an extreme high tensile strength and is rotten without separating the material, for example, a window profile must be made.
