Die vorliegende Erfindung betrifft ein Verbindungselement gemäß dem Oberbegriff des Anspruchs 1.
5The present invention relates to a connecting element according to the preamble of claim 1.
5
Derartige Verbindungselemente werden beispielsweise durch Federn gebildet, die in als Nuten gestaltete Aufnahmen der Platten eingesteckt und in diesen mit den zugeordneten Platten verleimt oder verklebt sind.Such connecting elements are formed, for example, by springs that are inserted into grooves in the panels and glued or bonded to the associated panels.
In diesem Sinne können die Verbindungselemente auch als Dübel ausgebildet sein, die in plattenseitige Löcher eingesteckt und ebenfalls durch Verleimen oder Verkleben festgelegt sind.In this sense, the connecting elements can also be designed as dowels, which are inserted into holes in the panel and are also fixed by gluing or adhesive.
Diese Federn oder Dübel bestehen bislang aus Holz oder einem Holzwerkstoff, beispiels weise aus einem Spanplattenwerkstoff.These springs or dowels are currently made of wood or a wood-based material, such as chipboard.

Da solche Verbindungselemente in großen Stückzahlen Verwendung finden, z. B. zum Verbinden von Küchen-Arbeitsplatten, wird eine notwendige Menge an Verbindungselementen lagermäßig gehalten.Since such fasteners are used in large quantities, e.g. for connecting kitchen worktops, a necessary quantity of fasteners is kept in stock.
Allerdings sind sie dabei den üblichen klimatischen Veränderungen innerhalb eines Raumes ausgesetzt, wie Feuchtigkeits- und/oder Temperaturschwankungen, die die maßliche Beschaffenheit der Verbindungselemente beeinflussen, so daß sie vielfach nicht mehr zu verwenden sind.However, they are exposed to the usual climatic changes within a room, such as humidity and/or temperature fluctuations, which affect the dimensional properties of the connecting elements, so that in many cases they can no longer be used.
So ist durch Aufnahme von Luftfeuchtigkeit ein Aufquellen der Verbindungselemente zu beklagen, was dazu führt, daß diese nicht mehr problemlos in die maßlich angepaßten Aufnahmen der Platten eingesetzt werden können, vielfach sogar völlig unbrauchbar sind. Die sich daraus naturgemäß ergebenden Kostennachteile sind vor allem deshalb bedeutsam, weil, wie erwähnt, solche Verbindungselemente in großen Stückzahlen hergestellt und eingesetzt werden.The absorption of air humidity causes the connecting elements to swell, which means that they can no longer be easily inserted into the dimensionally adapted slots in the panels and are often completely unusable. The cost disadvantages that naturally result from this are particularly significant because, as mentioned, such connecting elements are manufactured and used in large quantities.
Um diese Nachteile zu vermeiden, ist zwar schon versucht worden, Verbindungselemente aus Kunststoff herzustellen, jedoch ist ein solcher aufgrund der geringen Verbindungsfähigkeit mit Leim oder Kleber grundsätzlich wenig geeignet, eine Alternative zu den bekannten Verbindungselementen zu bilden.In order to avoid these disadvantages, attempts have already been made to produce connecting elements made of plastic, but due to the low bonding ability with glue or adhesive, such a material is fundamentally unsuitable as an alternative to the known connecting elements.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Verbindungselement der gattungsgemäßen Art so auszubilden, daß eine bessere Form- und Maßstabilität erreicht wird.
25The present invention is therefore based on the object of designing a connecting element of the generic type in such a way that better shape and dimensional stability is achieved.
25
Diese Aufgabe wird durch ein Verbindungselement gelöst, das die Merkmale des Anspruchs 1 aufweist.This object is achieved by a connecting element having the features of claim 1.
Ein solches Verbindungselement besitzt eine ganze Reihe von Vorteilen, die jeweils für sich, insbesondere aber in der Summe eine wesentliche Verbesserung gegenüber dem Stand der Technik darstellen.Such a connecting element has a whole series of advantages, each of which individually, but especially in total, represents a significant improvement over the state of the art.

Anmeldetext vom 23.11.2000 Seite 3Registration text dated 23.11.2000 Page 3
So ist zunächst einmal zu nennen, daß das neue Verbindungselement absolut formstabil, vor allem aber maßstabil ist, unabhängig von den klimatischen Veränderungen wie Luftfeuchtigkeitsschwankungen oder dergleichen, so daß auch eine längerfristige Lagerung keinen Einfluß auf die Verwendungsfähigkeit der Verbindungselemente hat.First of all, it should be mentioned that the new connecting element is absolutely dimensionally stable, but above all it is dimensionally stable, regardless of climatic changes such as fluctuations in humidity or the like, so that even long-term storage has no influence on the usability of the connecting elements.
Überdies besitzen Biopolymere sehr gute Haftungseigenschaften hinsichtlich eines aufgetragenen Klebers oder Leims, die denen von Holz oder Holzwerkstoffen nicht nachstehen.In addition, biopolymers have very good adhesion properties with regard to an applied adhesive or glue, which are not inferior to those of wood or wood-based materials.
Durch eine Aufrauhung der Oberfläche kann diese Haftungseigenschaft sogar noch verbessert werden, wobei diese Aufrauhung durch eingeprägte Vertiefungen oder dergleichen gebildet sein kann.
15This adhesion property can be further improved by roughening the surface, whereby this roughening can be formed by embossed depressions or the like.
15
Zweckmäßigerweise wird dem Biopolymer Verstärkungsmaterial zugefügt, z. B. in Form von Hanf, Stroh oder anderen, faserigen Materialien, so daß die Bruchfestigkeit der Verbindungselemente noch verbessert wird.It is advisable to add reinforcing material to the biopolymer, e.g. in the form of hemp, straw or other fibrous materials, so that the breaking strength of the connecting elements is further improved.
Grundsätzlich ist Biopolymer ebenso zu verarbeiten wie Kunststoff, d. h., die Verbindungselemente können im Spritzgußverfahren hergestellt werden. Hierbei kann das Biopolymer auf Ligninbasis vorliegen, wobei Lignin Reststoffe aus der Papierverarbeitung sind.Basically, biopolymer can be processed in the same way as plastic, i.e. the connecting elements can be manufactured using the injection molding process. The biopolymer can be lignin-based, with lignin being waste products from paper processing.
Da Biopolymer ein natürlicher Rohstoff ist und vielfach als „flüssiges Holz" bezeichnet wird, ist es biologisch abbaubar und von daher bei der bekannten Entsorgungsproblematik nicht zu beachten.Since biopolymer is a natural raw material and is often referred to as "liquid wood", it is biodegradable and therefore does not have to be considered in the known disposal problems.
Da, wie erwähnt, der Einsatz von Biopolymer die Möglichkeit bietet, Verbindungselemente im Spritzgußverfahren herzustellen, ist auch eine äußerst kostengünstige Fertigung möglich, so daß sich insgesamt, unter Beachtung der praktisch nicht mehrSince, as mentioned, the use of biopolymers offers the possibility of producing connecting elements using the injection molding process, extremely cost-effective production is also possible, so that overall, taking into account the practically no longer

vorkommenden maßlichen Veränderung und dem sich daraus ergebenden Ausschuß, eine erhebliche Kostenreduzierung ergibt.occurring dimensional changes and the resulting waste, results in a significant cost reduction.
Die Form der Verbindungselemente ist prinzipiell frei wählbar. Neben den genannten Federn und Dübeln, die wie die bekannten Holzdübel auch eine profilierte Oberfläche aufweisen können, sind auch andere Formen denkbar, je nach Erfordernis.In principle, the shape of the connecting elements can be freely chosen. In addition to the springs and dowels mentioned, which can also have a profiled surface like the well-known wooden dowels, other shapes are also conceivable, depending on requirements.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der beigefügten Zeichnung beschrieben.An embodiment of the invention is described below with reference to the accompanying drawings.
Die einzige Figur zeigt ein in Platten eingesetztes Verbindungselement in einer Explosivdarstellung. The only figure shows a connecting element inserted into plates in an exploded view.
In der Figur sind zwei Platten, beispielsweise aus einem Holzwerkstoff wie einer Spanplatte dargestellt, die auf den einander zugewandten Seiten jeweils mit zwei parallel und mit Abstand zueinander angeordneten Nuten 3 versehen sind, wobei die Nuten 3 jeder Platte 2 in ihren Abständen und Abmaßen gleich sind, so daß nach einem Zusammenfügen beider Platten 2 eine flächenbündige Oberfläche gebildet wird.The figure shows two panels, for example made of a wood material such as a chipboard, which are each provided with two grooves 3 arranged parallel and at a distance from one another on the sides facing one another, the grooves 3 of each panel 2 being the same in their distances and dimensions, so that after joining the two panels 2 together, a flush surface is formed.
Die Verbindung der beiden Platten 2 erfolgt durch Verbindungselemente 4, die im vorliegenden Ausfühningsbeispiel als im Grundriß ellipsenförmige Federn ausgebildet sind, von denen eine dargestellt ist.The two plates 2 are connected by connecting elements 4, which in the present embodiment are designed as elliptical springs in plan view, one of which is shown.
Dabei entspricht die Dicke dieses Verbindungselementes 1 der Breite der zugeordneten Nut 3, während die Länge dieser Nut 3 etwa der Länge des Verbindungselementes 1 angepaßt ist.The thickness of this connecting element 1 corresponds to the width of the associated groove 3, while the length of this groove 3 is approximately adapted to the length of the connecting element 1.

Das Verbindungselement 1 wird etwa zur Hälfte in die zugeordnete Nut 3 gesteckt, wobei eine Verbindung mit dem anliegenden Holzwerkstoff durch einen aufgetragenen Leim oder Kleber erfolgt.The connecting element 1 is inserted approximately halfway into the associated groove 3, whereby a connection to the adjacent wood material is made by means of an applied glue or adhesive.
Für eine bessere Haftung sind die beiden Grundflächen des Verbindungselementes mit einer Profilierung 4 versehen, im vorliegenden Ausführungsbeispiel in Form einer Rautierung.For better adhesion, the two base surfaces of the connecting element are provided with a profiling 4, in the present embodiment in the form of a diamond pattern.
Indem die zweite Platte 2 im Bereich ihrer Nut 3 auf das Verbindungselement 1 aufgeschoben wird und in der zuvor beschriebenen Art und Weise verleimt oder verklebt wird, wird eine feste Verbindung der beiden Platten 2 erreicht.By pushing the second plate 2 onto the connecting element 1 in the area of its groove 3 and gluing or bonding it in the manner described above, a firm connection between the two plates 2 is achieved.
