Description
Die vorliegende Erfindung bezieht sich auf ein Verfahren zum Befestigen eines vorzugsweise hülsenförmigen und/oder geschlitzten Einsatzkörpers in einer Leichtbauplatte, die eine obere und eine untere Deckschicht aufweist, zwischen denen Füllmaterial, beispielsweise eine Wabenstruktur, angeordnet ist.The The present invention relates to a method of fastening a preferably sleeve-shaped and / or slotted insert body in a lightweight board, which has an upper and a lower surface layer between which filling material, for example, a honeycomb structure is arranged.
Im Weiteren betrifft die Erfindung eine derartige Leichtbauplatte mit einem, vorzugsweise hülsenförmigen und/oder geschlitzten, Einsatzkörper sowie ein Möbelteil mit einer Leichtbauplatte der vorstehend genannten Art.in the Furthermore, the invention relates to such a lightweight board with one, preferably sleeve-shaped and / or slotted, insert body as well as a furniture part with a lightweight panel of the aforementioned type.
Im
modernen Möbelbau
werden traditionelle Werkstoffe wie beispielsweise Span- oder Massivholzplatten
zunehmend durch leichte Konstruktionswerkstoffe ersetzt, um damit
den gesteigerten Ansprüchen
hinsichtlich Design und/oder flexibler Einsetzbarkeit gerecht zu
werden. Zu diesen leichten Konstruktionswerkstoffen zählen auch
Leichtbauplatten, die zudem eine günstige Alternative zu den traditionellen
Werkstoffen darstellen. Zur Montage von Beschlägen, wie z.B. Scharnieren,
Ausziehführungsschienen
von Schubladen oder zur Montage von Halterungen von Frontblenden
sind daher auch innovative Befestigungstechniken bekannt geworden.
Das Problem mit Leichtbauplatten der eingangs erwähnten Art
besteht in der Gefahr, dass die mechanischen Komponenten der Möbelbeschläge leicht
aus der Leichtbauplatte ausgerissen werden können. Eine Möglichkeit,
dieses Problem zu lösen,
besteht in der Verwendung von Einsatzkörpern in Leichtbauplatten. Mechanische
Halterungen in Leichtbauplatten, die im Wesentlichen wie Spreizdübel funktionieren,
sind beispielsweise aus der
Aufgabe der gegenständlichen Erfindung ist es daher, das Verfahren der eingangs erwähnten Gattung dahingehend zu verbessern, dass ein Einsatzkörper verbessert gegen ein Verdrehen und gegen ein Ausreißen desselben in einer Leichtbauplatte der eingangs erwähnten Art gehindert werden kann.task the figurative Invention is therefore, the method of the type mentioned to improve that an insert body improves against twisting and against a runaway the same in a lightweight panel of the type mentioned can be prevented.
Gemäß der erfindungsgemäßen Aufgabenstellung wir dies in einer vorteilhaften Ausgestaltung durch folgende Schritte erreicht:
- – Vorsehen einer im Wesentlichen sacklochförmigen Ausnehmung in der oberen Deckschicht und dem Füllmaterial, wobei die untere Deckschicht undurchbrochen bleibt,
- – Einsetzen des Einsatzkörpers in die Ausnehmung,
- – Verbinden des Einsatzkörpers mit der Innenseite der oberen Deckschicht und der Innenseite der unteren Deckschicht.
- Providing a substantially blind-hole-shaped recess in the upper cover layer and the filling material, wherein the lower cover layer remains uninterrupted,
- Inserting the insert body into the recess,
- - Connecting the insert body with the inside of the upper cover layer and the inside of the lower cover layer.
Vorteilhaft ist vorgesehen, dass der Einsatzkörper zumindest teilweise aus thermoplastischem Kunststoff besteht, der durch Wärmezufuhr und partielles Verschmelzen desselben mit der oberen Deckschicht und/oder mit der Innenseite der unteren Deckschicht verbunden wird. Durch eine Aufschmelzung des thermoplastischen Materials des Einsatzkörpers kann insbesondere sowohl an den Berührungsstellen der oberen als auch mit der unteren Deckschicht der Leichtbauplatte eine feste und stabile Verbindung ermöglicht werden. Das thermoplastische Material kann dabei teilweise in die Leichbauplatte eindringen und bewirkt eine Verankerung des Einsatzkörpers mit der Leichtbauplatte. In diesem Zusammenhang kann es zweckmäßig sein, wenn der Einsatzkörper einen Boden aufweist, der im Wesentlichen vollständig mit der Innenseite der unteren Deckschicht verbunden wird.Advantageous is provided that the insert body at least partially Thermoplastic consists of, by heat and partially fusing it with the top cover layer and / or is connected to the inside of the lower cover layer. By melting the thermoplastic material of the insert body can especially both at the points of contact the upper and the lower cover layer of the lightweight board a solid and stable connection will be made possible. The thermoplastic Material can partially penetrate into the Leichbauplatte and causes anchoring of the insert body with the lightweight panel. In this context, it may be useful if the insert body a Having bottom that is substantially complete with the inside of the lower cover layer is connected.
Unter „Innenseite der oberen- bzw. unteren Deckschicht" sei im Zusammenhang mit der vorliegenden Erfindung jeweils diejenige Seite der jeweiligen Deckschicht verstanden, die dem innen liegenden Füllmaterial zugewandt ist.Under "inside the upper and lower cover layer "is in connection with the present Invention each understood that side of the respective cover layer, the internal filling material is facing.
Eine vorteilhafte Ausführungsform der Erfindung ergibt sich dadurch, dass durch die Wärmezufuhr am Einsatzkörper zumindest ein Vorsprung – vorzugsweise an vordefinierter Stelle – ausgebildet wird, der zumindest teilweise mit der Innenseite der oberen Deckschicht und/oder mit der Innenseite der unteren Deckschicht zusammenwirkt. Im Ausgangszustand ist der Vorsprung günstigerweise noch nicht ausgebildet, wodurch der Einsatzkörper ungehindert in die sacklochförmige Ausnehmung eingesetzt werden kann. Erst durch die partielle Aufschmelzung wird ein Vorsprung der vorstehend beschriebenen Art ausgebildet.A advantageous embodiment The invention results from the fact that by the heat on the insert body at least one projection - preferably at a predefined position - being trained at least partially with the inside of the top cover layer and / or cooperates with the inside of the lower cover layer. In the initial state, the projection is advantageously not yet formed, whereby the insert body unhindered in the blind-hole-shaped Recess can be used. Only through the partial melting is formed a projection of the type described above.
Vorteilhafterweise erfolgt die Wärmezufuhr per Ultraschall, vorzugsweise über eine Sonotrode. Diese Art der Ultraschallschweißung ist an sich bereits bekannt und zeichnet sich durch sehr kurze Schweißzeiten und durch eine geringe thermische Belastung der Fügeteile aus, wodurch sich der Verzug derselben in vertretbaren Grenzen hält. Es sind zudem keine Zusatz- oder Verbrauchsmaterialien (beispielsweise Lösemittel, Klebstoffe) notwendig, wodurch diese Form der Schweißung als umweltfreundlich und wartungsarm gilt. Die resultierende Verbindung ist in der Festigkeit ähnlich dem Ausgangsmaterial. Durch diese Einbettung des Einsatzkörpers in die sacklochförmige Ausnehmung lassen sich hohe Verdreh- und Ausreißfestigkeiten erreichen. Alternativ oder ergänzend zur Ultraschallverschweißung können die Einsatzkörper auch durch Einkleben, Einleimen, mittels Reibschweißung durch Drehung und/oder Laserschweißen befestigt werden.Advantageously, the heat is supplied by ultrasound, preferably via a sonotrode. This type of ultrasonic welding is already known per se and is characterized by very short welding times and by a low thermal load on the parts to be joined, whereby the delay keeps within reasonable limits. There are also no additional or consumables (for example, solvents, adhesives) is necessary, making this form of welding is environmentally friendly and low maintenance. The resulting compound is similar in strength to the starting material. This embedding of the insert body in the blind hole-shaped recess can achieve high torsional and Ausreißfestigkeiten. Alternatively or in addition to ultrasonic welding, the insert body can also by Gluing, gluing, by friction welding by rotation and / or laser welding are attached.
Vorteilhaft ist vorgesehen, dass die Wärmezufuhr während des Eindrückens des Einsatzkörpers in die Leichtbauplatte erfolgt. Während des Eindrückens wird der Einsatzkörper gleichzeitig positioniert und teilweise aufgeschmolzen, wodurch die Gefahr einer Dislokation weitgehend vermieden werden kann.Advantageous is provided that the heat supply while of impressions of the insert body in the lightweight board is done. While of impressions becomes the insert body simultaneously positioned and partially melted, thereby the risk of dislocation can be largely avoided.
Zweckmäßigerweise ist vorgesehen, dass am Einsatzkörper ein Beschlagteil eines Möbels befestigt wird, insbesondere ein Scharnier, eine Schubladenführung oder eine Frontblende einer Schublade. Der Einsatzkörper kann grundsätzlich so ausgebildet sein, dass er sich für die Aufnahme von Schrauben, Stiften, Muttern, Bolzen oder dgl. eignet.Conveniently, is provided that on the insert body a fitting part of a piece of furniture is attached, in particular a hinge, a drawer slide or a front panel of a drawer. The insert body can basically so be educated that he is for the inclusion of screws, pins, nuts, bolts or the like. Is suitable.
Die Einbringung bzw. die Eindrückung des Einsatzkörpers in die Leichtbauplatte kann auf verschiedene Art und Weise erfolgen. Dabei kann es von Vorteil sein, wenn ein Stempel zum Eindrücken des Einsatzkörpers in die Leichtbauplatte in den Einsatzkörper hineinreicht. Auch kann dabei vorgesehen werden, dass der Stempel auf den Boden des Einsatzkörpers drückt. Alternativ oder ergänzend kann es zweckmäßig sein, wenn der Stempel gegen die Seitenwand des Einsatzkörpers drückt. Eine vorteilhafte Ausführungsform der Erfindung ergibt sich dadurch, dass die Einrichtung zur Wärmezufuhr und der Stempel durch ein und dieselbe Einrichtung gebildet wird. Vorteilhaft ist vorgesehen, dass die Wärmezufuhr, vorzugsweise über Ultraschall, durch eine Einrichtung erfolgt, die von oben in den Einsatzkörper eintaucht, wobei es zweckmäßig sein kann, dass der Stempel von einer Einrichtung zur Wärmezufuhr, vorzugsweise von einer Ultraschallquelle, gebildet wird. Da die Sonotrode bzw. der Stempel dauerhaft (Ultraschall-) Schwingungen ausgesetzt ist, sind die Anforderungen an das Material sehr hoch. Günstigerweise kann für die Sonotrode karbidbeschichtetes Titan eingesetzt werden.The Introduction or indentation of the insert body in the lightweight panel can be done in different ways. It may be advantageous if a stamp for pressing the insert body extends into the lightweight panel in the insert body. Also can be provided that the punch presses on the bottom of the insert body. alternative or in addition it may be appropriate when the punch presses against the side wall of the insert body. A advantageous embodiment The invention results from the fact that the device for supplying heat and the stamp is formed by one and the same device. It is advantageously provided that the heat supply, preferably via ultrasound, by a device that dips into the insert body from above, where appropriate can that the stamp from a device for the supply of heat, preferably from an ultrasound source. Because the Sonotrode or the stamp permanently (ultrasonic) vibrations exposed, the demands on the material are very high. Conveniently for the Sonotrode carbide-coated titanium can be used.
Eine weitere vorteilhafte Ausführungsform der Erfindung ergibt sich dadurch, dass der Einsatzkörper nach dem Einsetzen in die Leichtbauplatte radial erweitert wird und damit dessen Oberkante zumindest teilweise unter der Innenseite der oberen Deckschicht der Leichbauplatte anliegt.
