Then the top one The plate is lowered so that the layer system is pressed together becomes. The resins melt due to the over Plates supplied heat. Then the top one Plate raised. Grippers with suction cups are over brought the compressed layer system down and lowered. The suction cups are placed on the layer system and suck yourself tight. With the help of the sucked up Suction cups raise and lower the layer system transported out of the press. From this layer system panels with appropriate devices cut to size, usually around 1200 to 1300 mm long, five to twelve millimeters thick and about 200 mm are wide. Finally, grooves and tongues are considered milled panels are joined together using tongue and groove connected. They then form floor coverings or wall cladding.

Die verbundenen Paneele werden beispielsweise zu einem Fußbodenbelag zusammengesetzt, der unter der Bezeichnung Laminatfußboden bekannt ist.For example, the connected panels become one Flooring composed of the one under the label Laminate flooring is known.

Um eine Verleimung vermeiden zu können, ist aus der Druckschrift WO 96/27721 ein Steckprofil für ein Paneel bekannt, welches zunächst in bekannter Weise Nut und Federn umfasst. Darüber hinaus weist jede Feder auf einer Ober und/ oder Unterseite zumindest eine durchgehende Nase auf. Jede Nut ist mit Rillen so versehen, dass die Nase oder Nasen nach dem zusammenstecken zweier Paneele in die korrespondierende Rille gelangen. Es entsteht so eine formschlüssige Verbindung zwischen zwei Paneelen. Die Verwendung von Leim ist nicht erforderlich, um Paneele zu einem Fußboden oder einer Wandverkleidung zusammenzusetzen. In order to avoid gluing, is from the Publication WO 96/27721 a plug-in profile for a panel known, which first groove and in a known manner Includes feathers. In addition, each spring has one At least one continuous top and / or bottom Nose up. Each groove is provided with grooves that the nose or noses stick together after that two panels get into the corresponding groove. This creates a positive connection between two panels. The use of glue is not necessary around panels to a floor or wall covering reassemble.

Jedes Paneel weist an seinen beiden Längs- und an seinen beiden Querseiten eine Nut oder eine Feder auf.Each panel shows on its two longitudinal and on its a groove or a tongue on both transverse sides.

Wird ein Paneel mit seiner Längsseite versetzt mit einer Längsseite eines nächsten Paneels verbunden, so kann es erforderlich oder nützlich sein, dieses nach der formschlüssigen Verbindung seitlich verschieben zu können. Eine solche seitliche Verschiebung ist beispielsweise erwünscht, um so einen glatten seitlichen Rand zu erhalten. Auch ist es erwünscht, zwei Paneele, die mit ihren Querseiten aneinandergrenzen, nachträglich weiter zusammenzuschieben, um so eine geschlossene Oberfläche zu erhalten. If a panel is moved with its long side with one Long side of a next panel connected, see above it may be necessary or useful to do this after move the positive connection laterally can. Such a lateral shift is for example desirable to have such a smooth side Get edge. It is also desirable to have two panels, that adjoin one another with their transverse sides, retrospectively continue to push together to form a closed one To get surface.

DE-A-42 42 530 betrifft ein in Leichtbauweise hergestelltes Bauelement für Wände, Decken oder Dächer von Bauwerken, Die Bauelemente können durch ein entsprechendes federartiges Element mittels Verschwenken miteinander verbunden werden, wobei auf einer Seite der Feder Nasen vorgesehen sind, die in einer Ausnehmung des anderen Paneels einzurasten vermögen. Die Nasen erstrecken sich dabei über die gesamte Länge der Feder. Die derart hergestellte formschlüssige Verbindung der Bauelemente hat den Nachteil, dass die sich über die gesamte Länge der Feder erstreckenden Nasen unerwünschte Reibungskräfte verursachen, die ein Verschieben der Paneele entlang der Längsseiten erschweren.DE-A-42 42 530 relates to a lightweight component for Walls, ceilings or roofs of buildings, the building elements can be replaced by a corresponding spring-like element by pivoting with each other are connected, lugs are provided on one side of the spring, the can snap into a recess in the other panel. The noses extend over the entire length of the spring. The so produced positive connection of the components has the disadvantage that the over the entire length of the spring extending lugs undesirable frictional forces cause that make it difficult to move the panels along the long sides.

WO 00/28171 welches für die Frage der erfinderischen Tätigkeit nicht von Bedeutung ist offenbart eine Nut-/Federverbindung, die durch Verschwenken verriegelt werden können. Dabei sind ebenfalls auf der Unterseite der Feder über die gesamte Länge der Feder verlaufende Nasen vorgesehen, die in eine entsprechende Ausnehmung der unteren, starren Flanke der Nut des benachbarten Paneels eingreifen können.WO 00/28171 which is of no importance for the question of inventive step discloses a tongue and groove connection which can be locked by pivoting. Are also on the Underside of the spring noses running the entire length of the spring provided in a corresponding recess of the lower, rigid flank the groove of the adjacent panel can intervene.

Auch beim Stand der Technik, wie er aus den Druckschriften WO 96/27719 oder WO 96/27721 bekannt ist, erstreckt sich die Nase-Rille-Feder-Nut-Verbindung über die gesamte Längsseite zweier Paneele. Es sind starke Reibungskräfte zu überwinden, um nachträglich eine relative Verschiebung parallel zu einer Längsseite durchzuführen.Even with the state of the art, as it is from the publications WO 96/27719 or WO 96/27721 is known extends the nose-groove-tongue-and-groove connection over the entire Long side of two panels. There are strong frictional forces to overcome to a relative later To carry out displacement parallel to a long side.

Um solche Reibungskräfte zu vermeiden, wird gemäß der Druckschrift EP 0 698 162 B1 ein Spiel (Δ) zwischen einer Verriegelungsnut und einer Verriegelungsoberfläche an einem Verriegelungselement vorgesehen.In order to avoid such frictional forces, according to the Document EP 0 698 162 B1 a game (Δ) between one Locking groove and a locking surface provided on a locking element.

Gemäß der Patentanmeldung WO 97/47834 wird u. a. eine leimlose Verbindung zwischen zwei Paneelen vorgeschlagen, bei denen eine untere, hervorstehende Flanke einer seitlichen Nut elastisch ausgebildet ist. Die Geometrie, insbesondere in Bezug auf die Position des Vorsprungs auf der unteren Flanke ist derart ausgestaltet, dass das Verbinden von zwei Paneelen durch eine Bewegung, die im wesentlichen in einer Ebene stattfindet, ermöglicht wird.According to patent application WO 97/47834 u. a. a proposed glueless connection between two panels, where a lower, protruding flank of a lateral groove is elastic. The geometry particularly in relation to the position of the projection on the lower flank is designed such that connecting two panels by one movement, which essentially takes place in one level, is made possible.

WO 99/66152 offenbart Fußbodenpaneele mit Verbindungsmitfeln, Teile der Verbindungsmittel, nämlich die untere vorstehende Flanke bzw. Metallfeder muss zum Einrasten elastisch verformt werden.WO 99/66152 discloses floor panels with connecting means, parts of the Connection means, namely the lower projecting flank or metal spring must be elastically deformed to engage.

Auch Patentanmeldung GB 2 256 023 zeigt Paneele, bei denen die untere vorstehende Flanke einer Nut elastisch nachgeben muss, um ein Einrasten der Nut-Federverbindung zu ermöglichen. Patent application GB 2 256 023 also shows panels in which the lower the protruding flank of a groove must yield elastically in order to engage the To enable tongue and groove connection.

Nachteilhaft hat eine große Elastizität von Flanken zur Folge, dass die mechanische Verbindung in horizontaler Richtung wenig stabil ist.A disadvantage is the great elasticity of flanks Consequence that the mechanical connection in a horizontal Direction is not very stable.

Der Erfindung liegt die Aufgabe zugrunde, Paneele bereitzustellen, die miteinander leimlos und stabil verbunden werden können, und im Zusammengefügten Zustand seitlich verschoben werden können.The invention has for its object to provide panels, the glueless and stable bonded together can be, and in the assembled state can be moved laterally.

Die Aufgabe wird mit Hilfe eines Paneels mit den Merkmalen des ersten Anspruchs gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The task is carried out using a panel with the characteristics of the first claim. Advantageous configurations result from the subclaims.

Ein Paneel weist wenigstens eine seitlich eingefräste Nut auf, die durch zwei Flanken oder Schenkel gebildet wird. Die eine Flanke ragt über die andere hinaus, ist also länger als die andere. Beide Flanken sind starr, also im wesentlichen nicht elastisch. Eine Flanke ist starr im Sinne der Erfindung, wenn diese im Unterschied zur Lehre gemäß Druckschrift WO 97/47834 nicht elastisch so gebogen werden kann, dass ein Zusammenfügen durch Zusammenschieben zweier Paneele in einer Ebene möglich ist. In der längeren Flanke ist wenigstens eine Ausnehmung vorgesehen.A panel has at least one milled on the side Groove on, formed by two flanks or legs becomes. One flank protrudes beyond the other, is so longer than the other. Both sides are rigid essentially not elastic. Is a flank rigid in the sense of the invention if this differs for teaching according to publication WO 97/47834 not elastic can be bent so that an assembly by Two panels can be pushed together on one level is. There is at least one recess in the longer flank intended.

Ein zweites Paneel weist seitlich eine Feder auf, die in die vorgenannte Nut eingeführt wird, um zwei Paneele miteinander zu verbinden. Die Feder weist eine Mehrzahl von vorstehenden Nasen an ihrer Unter- oder Oberseite auf, die in die vorgenannte Ausnehmung der Flanke gelangen, wenn die zwei Paneele zusammengefügt werden. Jede Nase reicht dann vorzugsweise bis zum Boden der Ausnehmung.A second panel has a spring on the side that is inserted in the aforementioned groove to two panels connect with each other. The spring has one A plurality of protruding lugs on their top or bottom on, which get into the aforementioned recess of the flank, when the two panels are joined together. each The nose then preferably extends to the bottom of the recess.

Die Feder ist vorzugsweise so beschaffen, dass diese an der die Nasen aufweisenten Seite zumindest im Bereich ihres offenen Ende einen Abstand zur angrenzenden Flanke der Nut aufweist, wenn die Feder in die korrespondierende Nut gebracht worden ist. Es verbleibt also dann ein Zwischenraum zwischen der betroffenen Seite der Feder und der benachbarten Flanke. Dieser Zwischenraum reicht wenigstens bis zum offenen Ende der Feder, so dass das offene Ende die Flanke nicht berührt. Die Feder ist insbesondere abgeschrägt, so dass die Feder in diesem Bereich ähnlich wie bei einer Spitze zuläuft. Bei der betroffenen Seite handelt es sich um die Seite, die an die Flanke mit der Ausnehmung grenzt. Durch diese Schräge bzw. durch den bereitgestellten Freiraum wird es möglich, ohne großen Kraftaufwand durch eine Drehbewegung um die Verbindungsfuge zweier Paneele herum ein Paneel von einem weiteren Paneel zu lösen bzw. umgekehrt zwei Paneele durch die Drehbewegung miteinander zu verbinden. Die Feder wird also durch eine Drehbewegung in die korrespondierende Nut eines benachbarten Paneels hineinbewegt, ohne dass die Flanke mit der Ausnehmung stark gebogen werden müsste.The spring is preferably such that it is on the side with the lugs at least in the area of their open End a distance to the adjacent flank of the Has groove when the tongue in the corresponding Has been brought. So it remains Space between the affected Side of the spring and the adjacent flank. This The gap extends at least to the open end of the Spring so that the open end does not touch the flank. The spring is in particular beveled, so that the spring in this area similar to one Peak tapers. At the affected Side is the side that is on the flank borders with the recess. Through this slope or the space provided makes it possible with little effort by rotating around the Joint between two panels around one panel to solve another panel or vice versa two panels to connect with each other by the rotary motion. The spring is thus rotated into the corresponding one Moved in the groove of an adjacent panel, without the flank with the recess being strongly bent should be.

Eine solche Drehbewegung ist zwar aus der Druckschrift EP 0855482 B1 bekannt. Hieraus ist jedoch nicht bekannt, einen Zwischenraum durch Vorsehen von zum Beispiels der genannten Schräge bei einer Feder vorzusehen, um so das Verbiegen einer benachbarten elastischen Flanke vermeiden zu können. Such a rotary movement is indeed from the publication EP 0855482 B1 known. However, it is not known from this a space by providing, for example to provide the said slope for a spring, so the bending of an adjacent elastic To avoid flank.

Durch die erfindungsgemäße Geometrie ist es möglich, die Flanken der seitlichen Nut in einem Paneel starr auszugestalten. Die formschlüssige Verbindung zwischen zwei Paneelen ist dann besonders stabil.The geometry according to the invention makes it possible to the flanks of the side groove are rigid in a panel embody. The positive connection between two panels is then particularly stable.

Jede Nase reicht vorzugsweise bis zum Boden der Ausnehmung, um so zu kompensieren, dass die Feder im Bereich der Schräge nicht mehr wie beim Stand der Technik an die Flanke grenzt. Es ist nämlich eine derartige Kontaktfläche erforderlich, damit die eine Oberfläche eines Paneels gegenüber einer benachbarten Paneeloberfläche nicht infolge einer Belastung abgesenkt werden kann.Each nose preferably extends to the bottom of the recess so as to compensate for the spring in the area of the slope no longer on the flank as in the prior art borders. This is because such a contact surface is required so that one surface of a panel is opposite not as a result of an adjacent panel surface a load can be reduced.

In einer Ausgestaltung der Erfindung kontaktiert jede Nase mit einer weiteren Seite eine seitliche Wand der Ausnehmung, wenn zwei Paneele zusammengefügt sind. Es handelt sich dabei um die Seite bzw. Wand, durch die eine Verriegelung (parallel zur Oberfläche der Paneele) zwischen zwei Paneelen bewirkt wird. Dieser Kontakt ist notwendig, damit die Paneele fest miteinander verbunden sind. So kann sichergestellt werden, dass die Verbindungsfuge zwischen den beiden Paneelen dann keinen Spalt aufweist.In one embodiment of the invention, each nose contacts one with a further side side wall of the recess when two panels are joined together are. It is the page or Wall through which a lock (parallel to the surface of the panels) between two panels becomes. This contact is necessary for the panels are firmly connected. This can ensure be that the joint between the two Panels then has no gap.

Die Ausnehmung in der Flanke der Nut liegt insbesondere als Rille vor, die parallel zur angrenzenden Verbindungsfuge zwischen zwei Paneelen verläuft. Eine Ausnehmung kann natürlich auch andere Formen aufweisen. Beispielsweise könnte es sich bei der Ausnehmung um ein Langloch handeln, in das die korrespondierende Nase eines weiteren Paneels einrasten kann. The recess in the flank of the groove lies in particular as a groove that runs parallel to the adjacent connecting joint runs between two panels. A recess can of course also have other shapes. For example the recess could be a Act oblong hole into which the corresponding nose of a other panels can snap into place.

In einer Ausgestaltung der Erfindung ist ein Spalt oder Spiel zwischen der Seite der Feder, die die Abschrägung aufweist, und der hervorstehenden Flanke vorgesehen. Hierdurch wird das zusammenfügen zweier Paneele weiter erleichtert. Ein Spalt kann vorgesehen sein, da jede Nase den Boden der Ausnehmung kontaktiert und die Funktion des üblicherweise vorgesehenen Kontaktes zwischen Feder und Nut übernimmt. Das Spalt oder Spiel zwischen der Feder und der Nut kann sich auf einige hunderstel Millimeter, so zum Beispiel auf 3/100 mm als bevorzugte Untergrenze beschränken.In one embodiment of the invention there is a gap or Play between the side of the spring that the bevel has, and the protruding edge provided. This will continue the joining of two panels facilitated. A gap can be provided since each Nose contacts the bottom of the recess and the function the usual contact between Tongue and groove takes over. The gap or game between the tongue and the groove can add up to a few hundredths Millimeters, for example to 3/100 mm as preferred Limit the lower limit.

Die anspruchsgemäßen Paneele umfassen also solche Mittel an den Längs- und/ oder Querseiten, dass zwei Paneele hierüber formschlüssig miteinander verbunden werden können. Eine formschlüssige Verbindung im Sinne des Anspruchs liegt vor, wenn zwei zu einer ebenen Fläche zusammengesetzte Paneele aufgrund von Formschluss innerhalb der Ebene nur noch parallel zur Verbindungsfuge, nicht aber senkrecht hierzu verschoben werden können. Es ist jedoch noch möglich, ein Paneel um die Verbindungsfuge zu drehen und so zwei Paneele voneinander zu lösen. Bei dieser Bewegung verlässt ein Paneel die vorgenannte Ebene. Eine Verschiebung, bei der die Ebene nicht verlassen wird, findet bei einer solchen Drehbewegung also nicht statt.The panels according to the claim thus comprise such means on the long and / or short sides that two panels be positively connected to one another can. A positive connection in the sense of the claim is when two are combined to form a flat surface Panels due to positive locking inside the level only parallel to the connecting joint, but cannot be moved perpendicular to it. However, it is still possible to have a panel around the connecting joint to rotate and so two panels from each other to solve. During this movement, a panel leaves the aforementioned Level. A shift at the level is not left, takes place with such a rotary motion so not instead.

Der Formschluss wird im Unterschied zum Stand mit Hilfe einer Mehrzahl von Nasen bewirkt. Jede Nase weist einen Abstand zu einer benachbarten Nase auf. Auf diese Weise wird die Reibung herabgesetzt, die überwunden werden muss, um eine Verschiebung zweier Paneele parallel zur Verbindungsfuge durchzuführen. The form fit is different from the stand with the help of a plurality of noses. each Nose is at a distance from an adjacent nose on. In this way, the friction is reduced must be overcome in order to move two panels to be carried out parallel to the joint.

Es ist eine der Leistungen der Erfinder, erkannt zu haben, dass es nachteilhaft ist, wenn sich wie beim Stand der Technik eine Nase über die gesamte Länge einer Feder erstreckt. Statt eine solche langgestreckte Nase vorzusehen, wird bei der Erfindung eine Mehrzahl von Nasen vorgesehen, die sich lediglich über vergleichsweise kleine Strecken erstrecken. Auf der einen Seite wird durch diese Maßnahme erreicht, dass über die gesamte Länge einer Verbindungsfuge die gewünschte formschlüssige Verbindung sichergestellt ist und dass auf der anderen Seite unerwünschte Reibungskräfte herabgesetzt werden.It is one of the achievements of the inventors to have recognized that it is disadvantageous if, as with the stand technology a nose over the entire length of a feather extends. Instead of such an elongated nose to provide, is in the invention a plurality of noses are provided, which are only extend over comparatively small distances. On on the one hand this measure is achieved that over the entire length of a joint desired positive connection is ensured and that on the other hand undesirable frictional forces be reduced.

Es kann dem Fachmann überlassen bleiben, den Abstand zwischen zwei Nasen, die Ausdehnung jeder einzelnen Nase sowie die Zahl der Nasen pro Verbindungsfuge durch wenige Versuche so zu wählen, dass die vorgenannten gewünschten Wirkungen optimiert werden.The distance can be left to the expert between two noses, the expansion of each one Nose as well as the number of noses per connecting joint few attempts to choose so that the aforementioned desired Effects are optimized.

In einer vorteilhaften Ausgestaltung der Erfindung weist jedes Paneel an jeder Längs- oder Querseite eine Nut oder eine Feder auf. Die Feder wird in eine Nut eines benachbarten Paneels hineingeführt, um so zwei Paneele miteinander zu verbinden. Das Paneel umfasst ferner an seinen Längs- und Querseiten zumindest eine Rille oder eine Mehrzahl an Nasen. Die Rille oder Nase ist im wesentlichen senkrecht zu der Oberfläche des Paneels angebracht, die die Fußbodenoberfläche oder Wandverkleidungsoberfläche bildet. Die Position der Nasen oder Rillen ist so gewählt, dass im verbundenen Zustand zweier Paneele die Nasen in wenigstens eine Rille gelangen, so dass hierdurch die gewünschte formschlüssige Verbindung bewirkt wird.In an advantageous embodiment of the invention each panel has one on each long or short side Groove or a spring. The tongue is in a groove of one inserted into adjacent panels to create two panels connect with each other. The panel also includes at least one on its long and short sides Groove or a plurality of noses. The groove or nose is essentially perpendicular to the surface of the panel attached to the floor surface or wall covering surface forms. The position of the noses or grooving is chosen so that when connected two panels the noses get into at least one groove, so that the desired positive Connection is effected.

Die vorgenannte Ausführungsform stellt ein einfaches und zuverlässig wirkendes Beispiel für anspruchsgemäße Paneele dar. Die Nasen sind an der Längs- oder Querseite des Paneels vorgesehen, an der eine Feder angebracht ist. Die Längs- oder Querseite des Paneels, die eine Nut aufweist, umfasst dann wenigstens eine Rille.The aforementioned embodiment is simple and reliable-looking example of sophisticated Panels. The noses are on the Longitudinal or transverse side of the panel provided on the a spring is attached. The long or short side of the panel, which has a groove, then comprises at least one groove.

In der Erfindung weisen die Nasen entlang einer Längs- oder Querseite einen gleichmäßigen Abstand zueinander auf. Sie sind also entlang einer Längs- oder Querseite regelmäßig angeordnet. Auf diese Weise wird sichergestellt, dass Verbindungskräfte zwischen zwei Paneelen gleichmäßig verteilt entlang der gesamten Verbindungsfuge wirken.In the invention, the noses point even along a long or short side Distance from each other. So you're along one Regularly arranged on the long or short side. To this This ensures that connecting forces between two panels evenly distributed along the entire joint.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung entspricht der Abstand zwischen zwei Nasen in etwa der Länge einer Oberkante einer Nase entlang der Längs- oder Querseite. Es hat sich gezeigt, dass bei dieser Ausdehnung bzw. Dimensionierung der Nasen und Abstände einerseits eine zuverlässige formschlüssige Verbindung zwischen zwei Paneelen sichergestellt ist und andererseits unerwünschte Reibungskräfte deutlich reduziert werden.In a further advantageous embodiment of the invention corresponds to the distance between two lugs in about the length of an upper edge of a nose along the Longitudinal or short side. It has been shown that at this expansion or dimensioning of the noses and Distances on the one hand a reliable positive Connection between two panels is ensured and on the other hand, undesirable frictional forces be reduced.

In einer weiteren Ausgestaltung der Erfindung verläuft der Übergang von einer Oberkante einer Nase zu einer benachbarten Oberkante einer Nase kreisförmig. Dieser Übergang kann durch Fräsen besonders einfach und preiswert hergestellt werden.In a further embodiment of the invention the transition from an upper edge of a nose to one adjacent top edge of a nose circular. This Milling can be particularly easy and inexpensive by milling getting produced.

Sind zwei Paneele über ihre Längsseiten miteinander verbunden und wird ein drittes Paneel hinzugefügt, so entsteht regelmäßig der Bedarf, zwei Paneele an den (im allgemeinen kurzen) Querseiten miteinander zu verbinden. Es ist dann nicht mehr möglich, die vorgenannte Drehbewegung um eine Verbindungsfuge herum durchzuführen, um so zwei (insbesondere kurze) Seiten von zwei Paneelen miteinander zu verbinden. Um dennoch verbinden zu können, ist eine Nut-Feder-Verbindung vorgesehen, die wie folgt ausgestaltet ist. Die Nut weist gleich lange Schenkel bzw. Flanken auf. Wenigstens eine Flanke bzw. ein Schenkel ist elastisch. Ein Schenkel weist innerhalb der Nut eine Ausnehmung auf. Die Feder umfasst eine Nase. Wird die Feder des einen Paneels in die Nut des anderen Paneels geschoben, so wird zuvor der elastische Schenkel so gebogen, dass ein Zusammenfügen möglich ist. Schließlich rastet die Nase in der Ausnehmung ein. Die zwei Paneele sind dann miteinander so verbunden, dass kein Spalt oder Spiel bei der zugehörigen Verbindungsfuge verbleibt.Are two panels together along their long sides connected and a third panel is added, see above there is a regular need to attach two panels to the (in general short) cross pages to connect. It is then no longer possible to use the aforementioned Rotate around a joint, so two (especially short) sides of two To connect panels together. To connect anyway a tongue and groove connection is provided, which is designed as follows. The groove has the same long legs or flanks. At least one flank or one leg is elastic. One leg points inside the groove has a recess. The spring embraces a nose. The tongue of one panel is in the groove of the other panel, so the elastic is first Leg bent so that it can be joined together is. Finally, the nose snaps into the recess on. The two panels are then connected to each other that no gap or play in the associated Connection joint remains.

Zwei Paneele werden bei der vorgenannten Ausführungsform über ihre Längskanten per Drehbewegung mit der Längskante einer dritten Paneele verbunden. Anschließend werden die zwei erstgenannten durch Verschieben aufeinander zugeschoben. Schließlich wird der elastische Schenkel des einen Paneels (nach unten oder oben) geeignet weggebogen, so dass die benachbarte Feder in die Nut gelangen kann. Anschließend rastet die Nase der zuletzt genannten Feder in die Ausnehmung der elastischen Nut ein. Die beiden zuerst genannten Paneele sind dann auch über ihre kurzen Kanten miteinander verbunden.Two panels are used in the aforementioned embodiment over its longitudinal edges by rotating with the Long edge of a third panel connected. Subsequently the first two are moved pushed towards each other. Eventually the elastic Leg of one panel (down or up) suitably bent away so that the adjacent spring in the groove can get. Then the nose snaps last mentioned spring in the recess of the elastic Groove one. The first two panels are then also connected to each other via their short edges.

Aus fertigungstechnischen Gründen nimmt der Abstand zwischen zwei Lippen der vorgenannten Nut zum offenen Ende hin zu. Es ist dann sehr viel besser und schneller möglich, eine Ausnehmung im Inneren der Nut zu fräsen.The distance increases for manufacturing reasons between two lips of the aforementioned groove to open End towards. Then it is much better and faster possible to mill a recess inside the groove.

Die Form;der Feder ist dann bevorzugt an die vorgenannte Form der Nut anzupassen, um einen guten Halt sicherzustellen. Die Feder verjüngt sich also zum offenen Ende hin.The shape; the spring is then preferred to the aforementioned Adjust the shape of the groove to ensure a good grip. The spring tapers to the open End.

Um die vorgenannten drei Paneele schonend voneinander zu trennen, werden zunächst die zwei erstgenannten Paneele durch eine Drehbewegung mit umgekehrtem Drehsinn von der dritten Paneele gelöst. Um mögliche Beschädigungen zu vermeiden, wird nun nicht die elastische Flanke so gebogen, dass die zugehörige Feder aus der Nut herausgezogen werden kann. Statt dessen wird die Feder durch Verschieben entlang der Verbindungsfuge seitlich herausgezogen.To the above three panels gently from each other to separate, are the first two panels mentioned through a rotational movement with the opposite direction of rotation detached from the third panel. For possible damage to avoid is now not the elastic Flank bent so that the associated spring from the Groove can be pulled out. Instead, the Spring by sliding along the connection joint pulled out to the side.

Die Figuren 1 bis 3 verdeutlichen eine erst Ausführungsform von langen Seiten eines Paneels mit den starren Flanken. In der Figur 4 wird eine Ausführungsform von kurzen Querseiten mit elastischen Flanken gezeigt. Figur 5 zeigt eine besonders bevorzugte Ausführungsform mit Maßen in Millimetern. Figur 6 zeigt die Ausführungsform gemäß Figur 5 unter Auslassung der Maßangaben. Figur 7 zeigt ein besonders bevorzugtes Profil an den Querseiten eines Paneels.Figures 1 to 3 illustrate a first embodiment from long sides of a panel with the rigid Flanks. An embodiment is shown in FIG shown from short transverse sides with elastic flanks. Figure 5 shows a particularly preferred embodiment with dimensions in millimeters. Figure 6 shows the embodiment according to FIG. 5, omitting the dimensions. Figure 7 shows a particularly preferred profile the short sides of a panel.

Fig. 1 zeigt einen Schnitt durch zwei miteinander formschlüssig im Sinne der Erfindung verbundene Paneele 1 und 2. Paneel 1 weist an einer Längsseite eine Nut 3 auf. An einer Längsseite des Paneels 2 ist eine Feder 4 vorgesehen. Die Feder 4 ist in die Nut 3 hineingedreht worden und befindet sich also in der Nut 3. Die Verbindungsfuge 5 diente bei der Drehung als Drehachse. Bei der Verbindungsfuge 5 handelt es sich um die Fuge, die sich zwischen den beiden Paneelen 1 und 2 befindet. Die Längsseite mit der Rille 3 weist eine vorstehende untere Flanke 6 auf. Diese untere Flanke 6 ist an der langen Seite starr im Sinne der Erfindung, da es nicht möglich ist, diese hinreichend elastisch nach unten zu drücken, um so die Feder von Paneel 2 in die Nut 3 durch eine Bewegung in einer Ebene hineinschieben zu können. In die untere Flanke 6 ist als Ausnehmung eine Rille 7 im wesentlichen senkrecht von oben eingefräst worden. Die Rille 7 erstreckt sich über die gesamte Längsseite des Paneels 1. Paneel 2 weist unterhalb der Feder 4 eine weitere Ausnehmung 8 auf. An der Oberseite dieser weiteren Ausnehmung 8 sind Nasen 9 angebracht. In der Fig. 1 wird gezeigt, in welcher Weise eine Nase 9 in die Rille 7 hineinragt. Die Position der Nasen 9 ist so auf die Rille 7 abgestimmt, dass Paneel 1 mit dem Paneel 2 auf der Oberseite 10 der Paneelen dicht abschließt. Es verbleibt also kein Spalt an der Oberfläche bei der Verbindungsfuge. Soweit es für die Sicherstellung einer geschlossenen Oberfläche 10 nicht erforderlich ist, ist zwischen einer Nase 9 und einer Rille 7 ein Spalt 11 vorgesehen. Probleme aufgrund von Fertigungstoleranzen werden so vermieden. Ferner wird die Handhabung beim Verbinden zweier Paneele vereinfacht. Die Feder 4 weist an ihrer Unterseite eine Schräge 12 auf. An dieser Unterseite läuft die Feder 4 also spitz zu. Die Schräge 12 ist vorgesehen, um die Feder 4 in die Nut 3 durch eine Drehbewegung störungsfrei hineindrehen zu können, ohne den starren Schenkel 6 bzw. die untere starre Flanke merklich nach unten biegen zu müssen. Das Ende der Feder 4 ragt nicht vollständig in die Nut 3 hinein, so dass ein Spalt 13 verbleibt. Probleme, die sich aus Fertigungsungenauigkeiten ergeben können, werden durch Vorsehen dieses Spaltes vermieden. Die Oberseite der Nut 3 mündet nach außen in eine Schräge 14 ein. Hierdurch verbleibt an dieser Stelle ebenfalls ein Spalt zwischen den beiden Paneelen 1 und 2. Durch Vorsehen der Schräge 14 wird weiterer Raum bereitgestellt, der für das Hineindrehen der Feder 4 in die Nut 3 erforderlich ist. Die Nase 9 reicht bis zum Boden der Rille 7.Fig. 1 shows a section through two interlocking Panels connected in the sense of the invention 1 and 2. Panel 1 has a groove 3 on one long side on. A spring 4 is located on one long side of the panel 2 intended. The tongue 4 is screwed into the groove 3 and is therefore in groove 3. The connecting joint 5 served as the axis of rotation during rotation. at the connecting joint 5 is the joint that is between the two panels 1 and 2. The Long side with the groove 3 has a protruding lower one Edge 6 on. This lower edge 6 is on the long side rigid in the sense of the invention since it is not it is possible to make them sufficiently elastic downwards Press, so that the tongue of panel 2 is in the groove 3 by pushing in on a plane can. In the lower edge 6 is a recess Groove 7 milled substantially vertically from above Service. The groove 7 extends over the entire Long side of the panel 1. Panel 2 points below the Spring 4 a further recess 8. At the top this further recess 8 lugs 9 are attached. 1 shows the manner in which a nose 9 protrudes into the groove 7. The position of the lugs 9 is matched to groove 7 so that panel 1 with the panel 2 on the top 10 of the panels tight concludes. So there is no gap on the surface at the joint. So much for ensuring a closed surface 10 does not is required is between a nose 9 and one Groove 7 provided a gap 11. Problems due to Manufacturing tolerances are avoided. Furthermore, handling when connecting two panels is simplified. The spring 4 has a bottom Slant 12 on. The spring 4 runs on this underside so pointed. The slope 12 is provided to the Tongue 4 in the groove 3 by a rotational movement without interference to be able to screw in without the rigid leg 6 or the lower rigid flank noticeably downwards to have to bend. The end of the spring 4 does not protrude completely into the groove 3 so that a gap 13 remains. Problems arising from manufacturing inaccuracies can result by providing this gap avoided. The top of the groove 3 opens outwards in a slope 14. This leaves it Also place a gap between the two panels 1 and 2. By providing the bevel 14 is more Space provided for turning the Tongue 4 in the groove 3 is required. The nose 9 extends to the bottom of groove 7.

Fig. 2, Darstellung a, zeigt eine frontale Sicht auf die Längsseite des Paneels 2 mit der Feder 4 und den Nasen 9. Der Übergang von einer Nasenoberkante einer Nase 9 verläuft zu einer benachbarten Nasenoberkante in Form eines kreisförmigen Bogens, wie er durch die kreisförmige Linie 15 angedeutet wird. Das Vorsehen eines solchen Überganges ermöglicht eine besonders einfache Fertigung der voneinander getrennten Nasen 9. Die Nasen 9 sind gleichmäßig entlang der Längsseite verteilt. Der Abstand zwischen zwei Nasen 9 entspricht in etwa der Länge einer Nase 9 entlang der Längsseite, wie aus Fig. 2, Darstellung a, ersichtlich ist.Fig. 2, representation a, shows a frontal view the long side of the panel 2 with the spring 4 and the Noses 9. The transition from the top edge of a nose Nose 9 runs to an adjacent top edge of the nose in Shape of a circular arch, as seen through the circular line 15 is indicated. The provision of one such a transition enables a particularly simple one Production of the separate noses 9. Die Noses 9 are evenly distributed along the long side. The distance between two lugs 9 corresponds to about the length of a nose 9 along the long side, such as 2, illustration a, can be seen.

Fig. 2, Darstellung b, zeigt das Paneel 2 von der Unterseite. Durch schraffierte Flächen wird die Position der Nasen angedeutet.Fig. 2, representation b, shows the panel 2 from the bottom. The position is indicated by hatched areas hinted at the noses.

Durch das Vorsehen von Zwischenräumen zwischen den Nasen werden Reibungskräfte zwischen den Nasen 9 und der Rille 7 gering gehalten. Darüber hinaus gibt es entlang der gesamten Längsseite durch Formschluß bewirkte Verbindungskräfte zwischen zwei Paneelen. Einerseits ist so die zuverlässige gewünschte Verbindung sichergestellt. Andererseits ist eine Verschiebung entlang der Verbindungsfuge 5 vielfach noch ohne großen Kraftaufwand möglich.By providing gaps between the noses are frictional forces between the lugs 9 and Groove 7 kept low. In addition there is along connecting forces caused by positive locking of the entire long side between two panels. On the one hand is this ensures the reliable desired connection. On the other hand, there is a shift along the Joint 5 often without great effort possible.

Gemäß Figur 3 reicht die Nase 9 bis zum Boden der Rille 7 und berührt diesen, wenn die Feder 4 in die Nut 3 hineingesteckt ist. Ferner ist ein Spalt 17 zwischen der Unterseite der Feder 4 und dem benachbarten Schenkel 6 vorgesehen. Wird die Oberfläche 10 beispielsweise an der Position 16 in Pfeilrichtung belastet, so ist im wesentlichen der Kontakt zwischen der Nase 9 und der Rille 7 dafür verantwortlich, dass die Fuge 5 sich durch auftretende Hebelkräfte nicht nachteilhaft öffnet und ein Spalt entsteht, in den Verunreinigungen gelangen können. Der Kontakt sorgt also für eine Stabilisierung der gewünschten Verbindung, obwohl bei der Nut ein Spalt 17 an der Unterseite der Feder vorgesehen ist. Der Spalt 17 erleichtert das Zusammenfügen von zwei Paneelen wesentlich. According to Figure 3, the nose 9 extends to the bottom of the groove 7 and touches it when the tongue 4 in the groove 3rd is inserted. There is also a gap 17 between the underside of the spring 4 and the adjacent leg 6 provided. For example, the surface 10 loaded at position 16 in the direction of the arrow, see above is essentially the contact between the nose 9 and the groove 7 is responsible for ensuring that the joint 5 does not open disadvantageously due to leverage and a gap is created in which contaminants enter can. The contact therefore ensures stabilization the desired connection, even though the groove Gap 17 is provided on the underside of the spring. The gap 17 facilitates the joining of two panels essential.

Figur 4 bezieht sich auf eine kurze Seite, die einen Schenkel 6 zeigt, der elastisch im Sinne der Erfindung ist. Die Elastizität ist einerseits durch einen Schenkel 6 erreicht worden, der länger als der Schenkel 6 in den vorhergehenden Figuren ist. Des weiteren reicht die Nase 9 nicht bis zum Boden der Ausnehmung 7. Der Schenkel 6 muss also weniger stark nach unten gedrückt werden, um die Feder 4 in die Nut 3 hineinschieben zu können, ohne dass eine Dreh- oder Kippbewegung erforderlich wäre.Figure 4 refers to a short page, the one Leg 6 shows the elastic in the sense of the invention is. The elasticity is due to one leg 6 has been reached, which is longer than the leg 6 in the previous figures. Furthermore, that is enough Nose 9 not to the bottom of the recess 7. The leg 6 needs to be pushed down less, in order to be able to slide the tongue 4 into the groove 3, without the need for turning or tilting would.

Die gewünschte Elastizität kann natürlich alternativ oder ergänzend durch Wahl geeigneter Materialien bewirkt werden. Weiter ist es möglich, die Dicke des Schenkels hinreichend zu verringern, um die gewünschten elastischen Eigenschaften bereitzustellen.The desired elasticity can, of course, alternatively or additionally by choosing suitable materials become. It is also possible to change the thickness of the Thighs sufficiently to reduce the desired to provide elastic properties.

Bevorzugt weist auch der andere Schenkel der Nut 3 eine Ausnehmung auf. Dann sind eine oder mehrere Nasen auf der Oberfläche der Feder 4 vorgesehen, die in die Ausnehmung an der oberen Flanke gelangen und in dieser einrasten können. Die obere Flanke der Nut 3 ist dann ebenfalls elastisch im Sinne der Erfindung ausgestaltet. Auf diese Weise kann die Verriegelung verbessert werden.The other leg of the groove 3 preferably also has one Recess on. Then one or more noses are on the surface of the spring 4 provided in the recess get on the top flank and in this can snap into place. The upper flank of the groove 3 is then also designed elastically in the sense of the invention. In this way the locking can be improved become.

Weitere Beispiele, auf welche Weise eine kurze Seite mit elastischen, gleich langen Flanken ausgestaltet werden kann und die andere Seite mit hierzu korrespondierenden Kupplungselementen, finden sich in der österreichischen Patentschrift Nr. 405560. More examples of how a short page designed with elastic, equally long flanks and the other side with the corresponding one Coupling elements can be found in the Austrian Patent No. 405560.

Sollen die in der Figur 4 gezeigten Seiten von Paneelen 1 und 2 gelöst werden, so wird bevorzugt auf ein Auseinanderbiegen der Schenkel der Nut 3 verzichtet, da hierdurch leicht Schäden auftreten könnten. Statt dessen wird Paneel 2 zum Beispiel in die Papierebene von Figur 4 hineinverschoben. Rille 7 fungiert dann als Schiene. Dieser Schiene entlang gleitet dann die Nase 9, bis die Verbindung zwischen den beiden Paneelen gelöst ist.Should the sides of panels shown in Figure 4 1 and 2 are solved, it is preferred to bend apart the leg of the groove 3 is omitted because this could easily cause damage. Instead panel 2, for example, is in the paper plane of Figure 4 moved into it. Groove 7 then acts as Rail. The nose then slides along this rail 9 until the connection between the two panels is released is.

Figuren 5 und 6 zeigen die gleiche Ausführungsform. Figur 5 zeigt die genauen Maße in Millimetern. Figur 6 zeigt die Ausführungsform mit Bezugzeichen. An der Unterseite der Paneele ist eine Schicht 18 aus einem trittschalldämpfenden Material angebracht und fest mit den Paneelen verbunden, um so eine besonders gute und sichere Dämpfung zu bewirken.Figures 5 and 6 show the same embodiment. figure 5 shows the exact dimensions in millimeters. Figure 6 shows the embodiment with reference numerals. On the bottom the panel is a layer 18 of one impact sound absorbing material attached and firmly with connected to the panels in order to create a particularly good and to effect safe damping.

Die Nase 9 reicht bis zum Boden der Ausnehmung 7, um eine Abstützung, wie oben erläutert, zu bewirken. Alternativ oder ergänzend kann die Hervorhebung 19 am offenen Ende der Lippe 6 bis an das Ende der Ausnehmung 20, die durch die Nase 9 gebildet wird, heranreichen. So wird ein vergleichbare Abstützung bewirkt.The nose 9 extends to the bottom of the recess 7 to cause a support, as explained above. alternative or in addition, the highlight 19 on the open End of the lip 6 to the end of the recess 20, which is formed by the nose 9, reach. A comparable support is achieved in this way.

Die Maße gemäß Figur 5 sind so gewählt, dass keine praktisch Kraft aufgewendet werden muss, um zwei Paneele mittels einer Drehbewegung um die Verbindungskante herum zusammenzufügen. Es ist insbesondere nicht erforderlich, die Lippe 6 nach unten zu biegen, um zwei Paneele zusammenzufügen. The dimensions according to FIG. 5 are chosen so that none practically force must be applied to two panels by means of a rotary movement around the connecting edge to put together. In particular, it is not required to bend lip 6 down by two Join panels.

Gemäß Figur 5 weist die Nase auch an ihrer Oberseite eine leichte Schräge auf, an die die Oberseite der Nut 3 entsprechend angepasst ist. Die Nase verjüngt sich also zum offenen Ende hin, da sowohl an ihrer Oberseite, als auch an ihrer Unterseite entsprechende Schrägen vorgesehen sind. Die Schräge an der Oberseite erstreckt sich bevorzugt über eine längere Distanz im Vergleich zur Unterseite, um so ein Einführen der Nase in die Nut besonders einfach zu machen, wie Versuche gezeigt haben.According to Figure 5, the nose also has on its top a slight slope to the top of the groove 3 is adjusted accordingly. The nose tapers So towards the open end, because both on its top, as well as corresponding on their underside Slants are provided. The slope at the top preferably extends over a longer distance in the Compared to the bottom, so an insertion of the nose easy to make in the groove, like experiments have shown.

Figur 7 zeigt eine besonders bevorzugte Ausführungsform einer Querseite im Schnitt. Im wesentlichen weitet sich die Nut 3 zum offenen Ende hin aus, um die Ausnehmungen 7 schnell und zuverlässig fräsen zu können.Figure 7 shows a particularly preferred embodiment a transverse side in section. Essentially, it widens the groove 3 towards the open end around the recesses 7 to be able to mill quickly and reliably.
