Abstract

The panel (1) is connected to a further panel (2) in positive engagement by connecting devices consisting of a lateral groove (3) formed by two rigid flanks, one of which (6) is longer than the other. The longer flank has a recess (7) and the other panel has a lateral tongue (4) with a lug formation (9) on the lower or upper side. The lug formation can secure in the recess. The side of the tongue with the lug formation has an incline (12), so that in the joined state of the two panels there is a space between the incline and the longer rigid flank. The lug formation in the second state reaches to the bottom of the recess.

Description

Die Erfindung betrifft ein Steckprofil für ein Paneel.The invention relates to a plug profile for a panel.

Ein Paneel, zum Beispiel bekannt aus der Druckschrift EP 090 6994 A1, ist eine dünne Platte, die im allgemeinen länglich ist und seitlich, also an den Längs- und Querseiten zum Beispiel über Nuten und Federn mit weiteren Paneelen verbunden werden kann. So miteinander verbundene Paneele werden insbesondere als Fußbodenbelag oder als Wandverkleidung eingesetzt. Die Fuge, die dann durch die beiden Paneele gebildet wird, wird nachfolgend Verbindungsfuge genannt.A panel, for example known from the publication EP 090 6994 A1, is a thin plate, generally is elongated and laterally, i.e. on the long and short sides for example via grooves and tongues with other panels can be connected. Panels connected in this way are used in particular as flooring or as wall cladding used. The fugue then through the two Panels is formed, is subsequently connecting joint called.

Ein Paneel wird gemäß dem Stand der Technik u. a. durch ein Kurztakt-Pressverfahren wie folgt hergestellt. Auf eine mit Harz getränkte folienartige Schicht, welche "Gegenzugpapier" genannt wird, wird eine Trägerplatte gelegt. Hierauf wird eine weitere mit Harz getränkte, folienartige, mit einem Dekor versehene Schicht gelegt. Eine solche Schicht ist unter der Bezeichnung "Dekorpapier" bekannt. Eine nächste korund- sowie harzhaltige folienartige Schicht wird auf die Dekorschicht gebracht. Diese Schicht ist unter der Bezeichnung "Overlay" bekannt. Durch das Overlay wird die gewünschte Härte der Oberfläche eines Paneels erzielt. Das vorgenannte Schichtsystem wird mit Greifmitteln am Rand zusammen gegriffen und in eine Presse transportiert. Die Presse besteht im wesentlichen aus zwei parallel zueinander angeordneten Platten, die auf ungefähr 200 °C erhitzt sind. Das Schichtsystem wird auf die untere der beiden Platten aufgelegt. Anschließend wird die obere Platte so abgesenkt, dass das Schichtsystem zusammengepresst wird. Die Harze schmelzen aufgrund der über die Platten zugeführten Wärme. A panel is u. a. through a Short-cycle pressing process produced as follows. On a with Resin-impregnated film-like layer, which "backing paper" a support plate is placed. This will another resin-soaked, foil-like, with a Decorated layer laid. Such a layer is known as "decorative paper". Another one Corundum and resin-containing film-like layer is on the Brought decorative layer. This layer is under the The term "overlay" is known. Through the overlay desired hardness of the surface of a panel is achieved. The The aforementioned layer system is combined with gripping means on the edge grabbed and transported to a press. The Press essentially consists of two parallel to each other arranged plates, which are heated to about 200 ° C. The layer system is on the lower of the two plates hung up. Then the top plate is lowered so that the layer system is pressed together. The resins melt due to the heat supplied through the plates.

Anschließend wird die obere Platte angehoben. Greifer mit Saugnäpfen werden über das zusammengepresste Schichtsystem gebracht und abgesenkt. Die Saugnäpfe werden auf dem Schichtsystem aufgesetzt und saugen sich fest. Mit Hilfe der festgesaugten Saugnäpfe wird das Schichtsystem angehoben und aus der Presse heraustransportiert. Aus diesem Schichtsystem werden mit entsprechenden Vorrichtungen Paneele zugeschnitten, die üblicherweise circa 1200 bis 1300 mm lang, fünf bis zwölf Millimeter dick und circa 200 mm breit sind. Abschließend werden Nuten und Federn als gefräst. Über Nut und Feder werden Paneele miteinander verbunden. Sie bilden dann Fußbodenbeläge oder Wandverschalungen.Then the top plate is raised. Gripper with Suction cups are made using the compressed layer system brought and lowered. The suction cups are on the Layer system put on and suck themselves firmly. With the help of sucked up suction cups the layer system is raised and transported out of the press. From this layer system panels are cut with appropriate devices, which are usually around 1200 to 1300 mm long, are five to twelve millimeters thick and about 200 mm wide. Finally, grooves and tongues are milled as. About Nut panels are connected to each other. they form then 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. Jedes Paneel weist an seinen beiden Längs- und an seinen beiden Querseiten eine Nut oder eine Feder auf.In order to avoid gluing, is from the Publication WO 96/27721 a plug-in profile for a panel known, which first tongue and groove in a known manner includes. In addition, each spring has an upper and / or Underside at least one continuous nose. each Groove is grooved so that the nose or noses after putting two panels together in the corresponding groove. This creates one positive connection between two panels. The Use of glue is not required to make panels a floor or wall covering. 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, so it can required or useful to do this after the to be able to move positive connection laterally. Such a lateral shift is for example desirable so as to obtain a smooth side edge. It is also desirable to have two panels with their Adjacent cross sides, continue afterwards to create a closed surface receive.

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.In the prior art, as it is from the publications WO 96/27719 or WO 96/27721 is known, the extends Nose-groove-tongue-groove connection over the entire long side two panels. There are strong friction forces to be overcome to make a relative shift parallel to a Long side to perform.

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 on one Locking element provided.

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 the lower flank is designed such that the Joining two panels by one movement, which in the essentially takes place in one level.

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.The invention has for its object to provide panels, the glueless and stable bonded together can be.

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 groove milled on the side on, which is formed by two flanks or legs. The one flank protrudes over the other, so it is longer than the other. Both sides are rigid, so essentially not elastic. A flank is rigid in the sense of Invention if, in contrast to the teaching according to Document WO 97/47834 cannot be bent elastically in this way can do that by putting two together Panels in one level is possible. In the longer flank at least one recess is provided.

Ein zweites Paneel weist seitlich eine Feder auf, die in die vorgenannte Nut eingeführt wird, um zwei Paneele miteinander zu verbinden. Die Feder weist wenigstens eine vorstehende Nase an ihrer Unter- oder Oberseite auf, die in die vorgenannte Ausnehmung der Flanke gelangt, wenn die zwei Paneele zusammengefügt werden. Die Nase reicht dann bis zum Boden der Ausnehmung.A second panel has a spring on the side, which in the aforementioned groove is introduced to two panels together connect to. The spring has at least one protruding one Nose on its bottom or top that is in the aforementioned recess of the flank arrives when the two Panels are joined together. The nose then extends to Bottom of the recess.

Die Feder ist so beschaffen, dass diese an einer Seite (Unter- oder Oberseite) 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 Unter- oder Oberseite 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 Unter- oder Oberseite 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 designed so that it is on one side (Bottom or top) at least in the area of their open Has a distance from the adjacent flank of the groove, when the tongue has been brought into the corresponding groove is. So there is a gap between the affected top or bottom of the spring and the neighboring flank. This gap is at least enough to the open end of the spring so that the open end is the Flank not touched. The spring is special beveled so that the spring is similar in this area runs at a peak. At the affected sub or Top side is the side facing the flank borders with the recess. Through this slope or through the space provided becomes possible without much Exertion of force due to a rotary movement around the connecting joint two panels around one panel from another panel loosen or vice versa two panels by turning connect with each other. So the spring is replaced by a Rotational movement in the corresponding groove of an adjacent one Panels moved in without the flank with the Recess would have to be strongly bent.

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 EP 0855482 B1 known. However, it is not known from this one Gap by providing, for example, the above To provide an incline on a spring so as to bend to be able to avoid an adjacent elastic 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 Flanks of the lateral groove in a panel rigid embody. The positive connection between two Panels are then particularly stable.

Die Nase reicht 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. The nose extends to the bottom of the recess so as to compensate that the spring is not in the area of the slope borders on the flank more than in the prior art. It is namely such a contact surface is required so that one surface of one panel versus an adjacent one Panel surface not lowered due to stress can be.

Die Nase kontaktiert 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.The nose contacts another side with a side Wall of the recess when two panels are joined together. It is the side or wall through which one Locking (parallel to the surface of the panels) between two panels is effected. This contact is necessary so that the panels are firmly connected. So can ensure that the joint between the then there is no gap between the two panels.

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 Groove in front that is parallel to the adjacent joint runs between two panels. A recess can naturally also have other shapes. For example the recess could be an elongated hole, into which the corresponding nose of another panel 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 die 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. As a result, the joining of two panels continues facilitated. A gap can be provided because the nose Bottom of the recess contacted and the function of the usually provided contact between tongue and groove takes over. The gap or play between the spring and the Groove can extend to a few hundredths of a millimeter, so for Example on 3/100 mm as the preferred lower limit restrict.

Ein anspruchsgemäßes Paneel umfasst 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.A panel according to the claim therefore comprises such means the long and / or short sides that two panels over it can be positively connected. A positive connection within the meaning of the claim exists, if two panels assembled to form a flat surface due to positive locking within the level only parallel to the joint, but not perpendicular to it can be moved. However, it is still possible Panel to turn the joint and so two panels to separate from each other. With this move one leaves Panel the aforementioned level. A shift in which the Level is not left, takes place with such a rotary movement so not instead.

Der Formschluss wird im Unterschied zum Stand vorteilhaft 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 advantageous in contrast to the stand with the help of a plurality of noses. Every nose shows a distance to an adjacent nose. To this In this way, the friction that is overcome is reduced must be in order to move two panels parallel to the Connecting 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 einer Ausgestaltung 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 in the prior art a nose extends the entire length of a spring. Instead of providing such an elongated nose, at an embodiment of the invention a plurality of lugs provided that is only about comparatively small Stretch. On the one hand, through this Measure achieved over the entire length of a Joint the desired positive connection is ensured and that on the other hand undesirable frictional forces are 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 individual nose as well as the number of noses per connecting joint by a few Try to choose so that the aforementioned desired Effects are optimized.

In einer vorteilhaften Ausgestaltung der Erfindung weist ein 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. Ein 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, a Panel a groove or one on each long or short side Spring on. The tongue is in a groove of an adjacent one Panels inserted in order to close two panels together connect. A panel also includes on its longitudinal and Transverse sides at least one groove or a plurality of lugs. The groove or nose is substantially perpendicular to that Surface of the panel attached which the Forms floor surface or wall covering surface. The position of the lugs or grooves is chosen so that in the connected state of two panels at least the noses a groove, so that the desired positive connection is effected.

Die vorgenannte Ausführungsform stellt ein einfaches und zuverlässig wirkendes Beispiel für ein anspruchsgemäßes Paneel dar. Die Nase ist insbesondere 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 represents a simple and reliable-looking example of a sophisticated one Panel. The nose is particularly on the longitudinal or Transverse side of the panel provided on a spring is appropriate. The long or short side of the panel, the has a groove, then comprises at least one groove.

Diese Ausführungsform stellt jedoch lediglich ein Beispiel dar. Alternativ kann die Längs- oder Querseite des Paneels, die eine Nut aufweist, die Nasen umfassen. Dann ist die Rille an der oder den Längs- bzw. Querseiten vorgesehen, die die Federn aufweisen.However, this embodiment is only an example Alternatively, the long or short side of the panel, which has a groove that include lugs. Then it is Groove provided on the longitudinal or transverse sides, the which have feathers.

In einer Ausgestaltung der Erfindung weisen die Nasen entlang einer Längs- oder Querseite einen gleichmäßigen Abstand zueinander auf. Sie sind also entlang einer Längsoder Querseite regelmäßig angeordnet. Auf diese Weise wird sichergestellt, dass/Verbindungskräfte zwischen zwei Paneelen gleichmäßig verteilt entlang der gesamten Verbindungsfuge wirken. In one embodiment of the invention, the lugs have even along a long or short side Distance from each other. So you are along a longitudinal or Transverse side arranged regularly. That way ensures that / connecting forces between two Panels evenly distributed along the entire Connection joints work.

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 the distance between two lugs corresponds approximately to the length an upper edge of a nose along the longitudinal or Transverse side. It has been shown that with this expansion or dimensioning of the lugs and distances on the one hand reliable positive connection between two Panels is ensured and on the other hand undesirable Frictional forces can be significantly 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 turn the aforementioned to make a joint around so two (especially short) sides of two panels with each other connect. In order to still be able to connect, there is a tongue and groove connection provided, which is designed as follows. The groove has legs or flanks of the same length. At least one flank or leg is elastic. On Leg has a recess within the groove. The Feather covers one nose. The tongue of one panel is in the groove of the other panel is pushed, so the elastic legs bent so that they can be joined together is. Finally, the nose snaps into the recess. The two panels are then connected to one another in such a way that no gap or play in the associated 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 their longitudinal edges by rotating movement with the longitudinal edge connected to a third panel. Then the two former by moving on top of each other been postponed. Finally, the elastic leg of the a panel (down or up) appropriately bent away, see above that the adjacent tongue can get into the groove. Then the nose of the last-mentioned spring snaps in the recess of the elastic groove. The two first panels mentioned are then also over their short edges connected with each other.

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.For manufacturing reasons, the distance between two lips of the aforementioned groove towards the open end. It is then much better and faster possible, one Milling the 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 of the spring is then preferred to the aforementioned Adjust the shape of the groove to ensure a good grip. The spring tapers towards the open end out.

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 gently separate the aforementioned three panels from each other separate, the first two panels are first by a rotational movement with the opposite direction of rotation from the third panels detached. To avoid possible damage the elastic flank is not bent so that the associated tongue is pulled out of the groove can. Instead, the spring is moved along the joint is 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. In 4 shows an embodiment of short transverse sides shown with elastic flanks. Figure 5 shows one particularly preferred embodiment with dimensions in Millimeters. FIG. 6 shows the embodiment according to FIG. 5 omitting the dimensions. Figure 7 shows one particular preferred profile on 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 1 and 2 connected in the sense of the invention. Panel 1 has a groove 3 on one long side. At a A spring 4 is provided on the long side of the panel 2. The Spring 4 has been screwed into the groove 3 and is located itself in the groove 3. The joint 5 served in the Rotation as an axis of rotation. The connecting joint 5 is around the joint between the two panels 1 and 2 is located. The long side with the groove 3 has one protruding lower edge 6. This lower edge 6 is rigid on the long side in the sense of the invention since it it is not possible to make them sufficiently elastic downwards Press so that the tongue of panel 2 passes through groove 3 to be able to push in a movement in one plane. In the lower flank 6 is a groove 7 in the recess have been milled essentially vertically from above. The groove 7 extends over the entire long side of the panel 1. Panel 2 has a further recess below the spring 4 8 on. At the top of this further recess 8 are Noses 9 attached. 1 shows which A nose 9 protrudes into the groove 7. The position the lugs 9 are matched to the groove 7 in such a way 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 connecting joint. So much for ensuring a closed surface 10 is not required there is a gap 11 between a nose 9 and a groove 7 intended. Problems due to manufacturing tolerances are avoided. Furthermore, the handling of Connecting two panels simplified. The spring 4 instructs a slope 12 on its underside. On this bottom So the spring 4 is pointed. The slope is 12 provided to the spring 4 in the groove 3 by a To be able to turn in the rotation without interference, without the rigid leg 6 or the lower rigid flank noticeably to have to bend down. 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 be obtained by providing this gap avoided. The top of the groove 3 opens out into one Bevel 14. This leaves it at this point also a gap between the two panels 1 and 2. By providing the bevel 14 there is more space provided that for screwing the spring 4 into the Groove 3 is required. The nose 9 extends to the bottom of the 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 of the Long side of the panel 2 with the spring 4 and the lugs 9. The transition from a top edge of a nose 9 runs to an adjacent top edge of the nose in the form of a circular arc as defined by circular line 15 is indicated. The provision of such a transition enables a particularly simple manufacture of each other separate lugs 9. The lugs 9 are evenly along the Distributed along the long side. The distance between two lugs 9 corresponds approximately to the length of a nose 9 along the Long side, as can be seen from FIG. 2, illustration a.

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 of the Indicated 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 friction forces between the lugs 9 and the groove 7 kept low. In addition, there are along the entire Longitudinal forces caused by positive locking between two panels. On the one hand, it is the most reliable desired connection ensured. On the other hand, one In many cases, displacement along the connecting joint 5 possible without great effort.

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 FIG. 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 intended. If the surface 10, for example, on the Position 16 loaded in the direction of the arrow, so in essentially the contact between the nose 9 and the groove 7 responsible for ensuring that the joint 5 is Leverage does not disadvantageously open and a crack arises in which contaminants can get. The Contact thus stabilizes the desired one Connection, although a gap 17 at the groove Bottom of the spring is provided. The gap 17 makes joining two panels much easier.

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 that is elastic in the sense of the invention. The elasticity is, on the one hand, by a leg 6 been achieved, which is longer than the leg 6 in the previous figures. Furthermore, nose 9 is enough not to the bottom of the recess 7. The leg 6 must so less pressed down to the spring 4 to be able to slide into the groove 3 without one Rotation or tilting movement would be required.

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 can also be achieved by choosing suitable materials. It is also possible to have a sufficient thickness of the leg decrease to the desired elastic properties provide.

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 is provided, which in the recess the upper edge and can snap into it. The upper flank of the groove 3 is then also elastic in the Designed sense of the invention. In this way, the Locking can be improved.

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 with elastic, equally long flanks can be designed 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 1 shown in FIG and 2 are released, 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, in the paper plane of Figure 4 inside moved. Groove 7 then acts as a rail. This The nose 9 then slides along the rail until the connection between the two panels.

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. At the bottom of the Panels is a layer 18 of an impact sound absorbing Material attached and firmly attached to the panels to to effect such a particularly good and 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 by one Support, as explained above. Alternatively or In addition, the highlight 19 at the open end of the lip 6 to the end of the recess 20 through the nose 9 is formed. So it becomes a comparable one Support causes.

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 are practical Force must be applied to two panels using one Join the rotary motion around the connecting edge. In particular, it is not necessary to add the lip 6 bend down to join two 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 a top Slight slope towards the top of the groove 3 is adjusted accordingly. So the nose tapers to open end, since both on its top and on corresponding slopes are provided on its underside. The Slant at the top preferably extends over a longer distance compared to the bottom, so one Inserting the nose into the groove to make it particularly easy as 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, the Groove 3 towards the open end around the recesses 7 to be able to mill quickly and reliably.
