Description

Die Erfindung betrifft ein Bauelement für Bettrahmen, Unterbetten oder dgl. aus wenigstens einem Holzbauteil und wenigstens einem damit fest verbundenen Kunststoffbauteil.The invention relates to a component for bed frames, lower beds or the like. From at least one wooden component and at least one firmly connected plastic component.

Bettrahmen, Unterbetten oder dgl. werden üblicherweise aus verschiedenen Bauteilen gebildet. So besteht der eigentliche Tragrahmen häufig aus Holzteilen, an denen Kunststoffteile, z.B. Lagerböcke, Federleistenkappen, Achsplatten, u.s.w. befestigt sind. Diese Kunststoffteile werden üblicherweise mittels Schrauben am jeweiligen Holzteil befestigt. Diese Art der Herstellung von Bettrahmen, Unterbetten oder dgl. ist zum einen relativ aufwendig, zum anderen sind solche Schraubverbindungen je nach Qualität der verwendeten Holzbauteile häufig, zumindest über einen längeren Zeitraum, nicht sehr zuverlässig, denn die Schrauben können ggf. leicht ausreißen, so daß dann die Kunststoffteile nicht mehr sicher am betreffenden Holzbauteil gehalten sind.Bed frames, under beds or the like are usually made different components. So there is the real one Support frame often made of wooden parts, on which plastic parts, e.g. Bearing blocks, female connector caps, axle plates, etc. are attached. These plastic parts are commonly attached to the respective wooden part by means of screws. This way of producing bed frames, under beds or the like is relatively complex on the one hand, on the other are such screw connections depending on the quality of the wooden components used frequently, at least over a longer period Period, not very reliable, because the screws can easily tear out, so that the plastic parts no longer held securely on the wooden component in question are.

Grundsätzlich ist es bekannt, im wesentlichen aus Kunststoff bestehende Verankerungsteile mit Bauteilen aus Holz auf einfache Weise zu verbinden, in dem eine ebene Kontaktfläche des Verankerungsteils gegen die Oberfläche des Holzbauteiles gedrückt wird und insbesondere durch Anwendung von Ultraschall das Verankerungsteil dort aufgeheizt wird. Dadurch wird entweder eine Lackschicht des Holzbauteiles verflüssigt und verbindet sich mit dem Verankerungsteil oder das letztere wird an der Kontaktfläche angeschmolzen und verschweißt unmittelbar mit der Oberfläche des Holzbauteiles, in dem etwas geschmolzener Kunststoff in Poren an der Oberfläche desselben eindringt. In beiden Fällen erhält man allerdings nur eine verhältnismäßig schwache Verbindung zwischen den beiden Teilen, die größerer mechanischer Belastung nicht standhält, die bei Bettrahmen, Unterbetten oder dgl. zwangsläufig auftritt.Basically it is known, essentially made of plastic existing anchoring parts with wooden components easy to connect in a flat contact area of the anchoring part against the surface of the wooden component is pressed and especially by application the anchoring part is heated there by ultrasound. This creates either a layer of varnish on the wooden component liquefies and connects to the anchoring part or the latter is melted onto the contact surface and welds directly to the surface of the wooden component, in the somewhat melted plastic in pores penetrates the surface of the same. In both cases but only a relatively weak connection between the two parts, the greater mechanical stress does not withstand those with bed frames, under beds or Like. Inevitably occurs.

Aufgabe der Erfindung ist es deshalb, eine Lösung zu schaffen, mit der derartige Bauelemente aus wenigstens einem Holzbauteil und wenigstens einem Kunststoffbauteil auf möglichst einfache Weise zuverlässig und sicher fest miteinander verbunden werden können.The object of the invention is therefore to create a solution with such components from at least one Wooden component and at least one plastic component as possible simple, reliable and secure tightly together can be connected.

Diese Aufgabe wird bei einem Bauelement der eingangs bezeichneten Art erfindungsgemäß dadurch gelöst, daß das Holzbauteil wenigstens eine Verbindungsbohrung und das Kunststoffbauteil wenigstens einen in die Verbindungsbohrung eingesteckten Verbindungszapfen aufweist, wobei das freie Ende des Verbindungszapfens zugänglich ist und mittels einer durch Ultraschallverformung hergestellten Durchmesservergrößerung im Bereich des Bohrungsendes am Holzbauteil gehalten ist.This task is described in a component of the beginning Art solved according to the invention in that the Wooden component at least one connection hole and that Plastic component at least one in the connecting hole has inserted connecting pin, the free end of the connecting pin is accessible and by means of a diameter enlargement produced by ultrasonic deformation in the area of the bore end on the wooden component is held.

Bei der Herstellung werden die Verbindungszapfen des jeweiligen Kunststoffteils einfach in die Verbindungsbohrung eingesteckt, anschließend wird das aus der Verbindungsbohrung hinausstehende freie Ende des Verbindungszapfens mit Hilfe von Ultraschall und einer geeigneten Sonode in eine in die Sonode vorgegebene Form, z.B. Linsenkopf, gestaucht. Durch dieses Stauchen des plastifizierten Verbindungszapfens kommt es zu einem Hinterschnitt oder dgl., der das Kunststoffbauteil unlösbar am Holzbauteil hält. Die Herstellung wird also ersichtlich wesentlich vereinfacht, das ein aufwendiges Einbringen von Schrauben oder dgl. vollständig entfällt, außerdem ist ein Lösen der Verbindung der Bauteile nahezu ausgeschlossen.During manufacture, the connecting pins of each Plastic part simply in the connecting hole plugged in, then the connection hole protruding free end of the connecting pin with Using ultrasound and a suitable sonode in one form given in the sonode, e.g. Lenticular head, compressed. This upsetting of the plasticized connecting pin there is an undercut or the like Plastic component holds onto the wooden component. The production is obviously significantly simplified that a complicated insertion of screws or the like completely not applicable, moreover, loosening the connection Components almost impossible.

Bei der einfachsten Ausführungsform ist die Verbindungsbohrung des Holzbauteiles, wenn dieses beispielsweise als Bettholm ausgebildet ist, durchgehend ausgebildet. Der Verbindungszapfen ist dann länger als die Bohrungstiefe und kann auf einfache Weise befestigt werden.In the simplest embodiment, the connection hole of the wooden component, if this, for example, as Bed spar is formed, continuously formed. The connecting pin is then longer than the hole depth and can be easily attached.

Alternativ kann auch vorgesehen sein, daß die Verbindungsbohrung des Holzbauteiles als Sackbohrung ausgebildet ist, deren innenseitiges Ende in eine von außen zugängliche Queröffnung im Holzbauteil mündet. Die Queröffnung muß dann selbstverständlich so groß dimensioniert sein, daß man die Ultraschallsonode problemlos einführen kann, um die Durchmesservergrößerung des freien Endes des Verbindungszapfens des Kunststoffbauteiles herstellen zu können. Alternatively, it can also be provided that the connecting bore the wooden component is designed as a blind hole, the inside end of which is accessible from the outside Cross opening in the wooden component opens. The transverse opening must then of course, be dimensioned so large that the Ultrasound probe can easily insert to increase the diameter the free end of the connecting pin to be able to manufacture the plastic component.

Die Durchmesservergrößerung des Verbindungszapfens des Kunststoffbauteiles kann unterschiedliche Formen aufweisen. So kann die Durchmesservergrößerung beispielsweise konisch ausgebildet sein oder als Hinterschneidung ausgebildet werden, z.B. nach Art eines Linsenkopfes.The diameter increase of the connecting pin of the Plastic component can have different shapes. For example, the diameter increase can be conical be formed or be formed as an undercut, e.g. in the manner of a lens head.

Ferner kann vorteilhaft vorgesehen sein, daß das freie Ende des Verbindungszapfens mit einer zusätzlichen Abdeckkappe versehen ist, die ebenfalls aus Kunststoff besteht und während der Ultraschallverformung gleichzeitig am Verbindungszapfen befestigt wird.It can also be advantageously provided that the free end of the connecting pin with an additional cover cap is provided, which is also made of plastic and during the ultrasonic deformation at the same time on the connecting pin is attached.

Das erfindungsgemäße Bauelement kann aus verschiedenen Kunststoff- und Holzmaterialien gebildet werden.The component according to the invention can consist of different Plastic and wood materials are formed.

These plastic components 3 each have a connecting pin 4 on, which is dimensioned so that it in the respective connecting hole 2a, 2b, 2c of the wooden component 1 fits into it and with its free end 5 freely accessible from the respective Connection hole 2a, 2b, 2c protrudes.

Zur Bildung eines erfindungsgemäßen Bauelementes 6 ist der jeweilige Verbindungszapfen 4 des jeweiligen Kunststoffbauteiles 3 mittels einer durch Ultraschallverformung hergestellten Durchmesservergrößerung im Bereich des Bohrungsendes am Holzbauteil 1 gehalten. Die Durchmesservergrößerung erfolgt dabei jeweils in Anpassung an die Art der Ausbildung der Verbindungsbohrung. So ist sie in Anpassung an die konische Verbindungsbohrung 2a ebenfalls konisch ausgebildet, dies ist mit dem Bezugszeichen 5a angedeutet. In Anpassung an die Verbindungsbohrung 2b ist der Verbindungszapfen dieses Kunststoffbauteiles 3 im Endbereich konisch ausgebildet, dieses ist mit dem Bezugszeichen 5b angedeutet und in Anpassung an die zylindrische Verbindungsbohrung 2b ist die Durchmesservergrößerung als linsenförmige Hinterschneidung 5c ausgebildet.To form a component 6 according to the invention respective connecting pin 4 of the respective plastic component 3 by means of an ultrasonic deformation Enlargement of diameter in the area of the bore end held on wooden component 1. The increase in diameter takes place in each case in adaptation to the type of training the connecting hole. So she is adapting to the conical connecting bore 2a is also conical, this is indicated by reference number 5a. In The connection pin is adapted to the connection bore 2b this plastic component 3 conical in the end region formed, this is indicated by the reference numeral 5b and in adaptation to the cylindrical connecting bore 2b is the increase in diameter as a lenticular undercut 5c trained.

Um diese Befestigung der Kunststoffbauteile 3 am Holzbauteil 1 zu erreichen, wird nach dem Einsetzen der Kunststoffbauteile 3 (Fig. 2) eine geeignet gestaltete Ultraschallsonode auf das jeweilige freie Ende 5 der Verbindungszapfen 4 aufgesetzt, es erfolgt dann eine Plastifizierung der Verbindungszapfen 4 und eine anschließende Umformung (Stauchung) entsprechend der gewählten Sonodenform.Around this attachment of the plastic components 3 on the wooden component 1 is achieved after inserting the plastic components 3 (Fig. 2) a suitably designed ultrasound probe on the respective free end 5 of the connecting pin 4 put on, there is then a plasticization the connecting pin 4 and a subsequent forming (Compression) according to the selected sonode shape.

Zusätzlich kann das freie Ende des jeweiligen Verbindungszapfens 4 auch noch mit einer Abdeckkappe 7 aus Kunststoff versehen werden, die bei der Ultraschallbefestigung mitbefestigt wird.In addition, the free end of the respective connecting pin 4 also with a cover cap 7 made of plastic be provided, which are also attached to the ultrasound attachment becomes.

Anders als beim dargestellten Ausführungsbeispiel kann die Verbindungsbohrung im Holzbauteil 1 auch als Sackbohrung ausgebildet sein, diese Sackbohrung mündet dann in eine von außen zugängliche Queröffnung, vorzugsweise Querbohrung des Holzbauteiles 1, in welche eine Sonode zur entsprechenden Befestigung des in diesem Bereich hineinragenden freien Endes des Verbindungszapfens eingeführt werden kann. Das Kunststoffbauteil ist dann in gleicher Weise am Holzbauteil 1 gehalten.Unlike the illustrated embodiment, the Connecting hole in wooden component 1 also as a blind hole be formed, this blind bore then opens into one of externally accessible transverse opening, preferably transverse bore of the Wooden component 1, in which a sonode for the corresponding Attachment of the free protruding in this area End of the connecting pin can be inserted. The Plastic component is then in the same way on the wooden component 1 held.

Natürlich ist die Erfindung nicht auf das dargestellte Ausführungsbeispiel beschränkt. Weitere Ausgestaltungen sind möglich, ohne den Grundgedanken zu verlassen. So können die Holzbauteile 1 aus beliebigen Hölzern oder ähnlichen Stoffen bestehen, die Kunststoffbauteile 3 können ebenfalls aus beliebigen Kunststoffmaterialien bestehen, sofern sie die jeweils erforderliche Festigkeit aufweisen.Of course, the invention is not based on the illustrated embodiment limited. Other configurations are possible without leaving the basic idea. So they can Wooden components 1 made of any kind of wood or similar materials exist, the plastic components 3 can also be made any plastic materials, provided they are each have the required strength.
