Abstract

The invention relates to panels comprising coupling means which permit the panels to be interconnected by form fit. A first panel comprises a projecting edge positioned laterally on its underside as the coupling element. A second panel comprises a projecting edge positioned laterally on its upper side as the coupling element. One of the aforementioned edges has a first projecting locking element which engages in a corresponding first cavity or recess of the other edge when the two panels are joined together. The panels comprise additional coupling elements which lock the panels by form fit in a vertical direction, in relation to the surface of said panels. The coupling elements are configured in such a way that one panel can be connected to the other panel by form fit, by lowering the former in relation to the latter. Two panels of the aforementioned type can be interconnected without adhesive in a particularly rapid manner.

Description

Paneele mit Kupplungsmitteln Panels with coupling agents
Die Erfindung betrifft Paneele mit Kupplungsmitteln zur leimlosen Verbindung sowie ein Verfahren zum Verlegen der Paneele.The invention relates to panels with coupling means for glue-free connection and a method for laying the panels.
Ein Paneel, zum Beispiel bekannt aus der Druckschrift EP 090 6994' AI, ist eine im allgemeinen längliche, dünne. Platte, die 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 alsA panel, for example known from EP 090 6994 ' AI, is a generally elongated, thin. Panel that can be connected to other panels laterally, i.e. on the long and short sides, for example using grooves and tongues. Panels connected in this way are used in particular as
Fußbodenbelag oder als Wandverkleidung eingesetzt.Flooring or used as a wall covering.
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 „Dekorpa- pier" bekannt. Eine nächste korund- sowie harzhaltige folienartige Schicht wird auf die Dekorschicht gebracht. Diese Schicht ist unter der Bezeichnung „Over- lay" bekannt. Durch das Overlay wird die gewünschte Härte der Oberfläche eines Paneels erzielt. Das vorge- nannte 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. 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.According to the prior art, a panel is manufactured, inter alia, by a short-cycle pressing process as follows. A carrier plate is placed on a film-like layer impregnated with resin, which is called "backing paper". A further layer impregnated with resin, film-like and provided with a decor is placed thereon. Such a layer is known under the name "decorative paper" , A next layer of corundum and resin-containing film is applied to the decorative layer. This layer is known as "overlay". The desired hardness of the surface of a panel is achieved by the overlay. The above-mentioned layer system is gripped together at the edge with gripping means and transported to a press. The press essentially consists of two plates arranged parallel to each other, heated to approximately 200 ° C. The layer system is placed on the lower of the two plates, then the upper one The plate is lowered so that the layer system is pressed together. The resins melt due to the heat supplied through the plates. Then the top plate is raised. Grippers with suction cups are brought and lowered over the compressed layer system. The suction cups are placed on the layer system and suck themselves firmly. With the help of the suction cups that are sucked in, the layer system is raised and transported out of the press. From this layer system, panels are cut using appropriate devices, which are usually approximately 1200 to 1300 mm long, five to twelve millimeters thick and approximately 200 mm wide. Finally, the grooves and tongues are milled, and the tongue and groove are used to connect panels. They then form floor coverings or wall cladding.
Die verbundenen Paneele werden beispielsweise zu einem Fußbodenbelag zusammengesetzt, der unter der Bezeich- nung Laminatfußboden bekannt ist.The connected panels are, for example, put together to form a floor covering, which is known under the name laminate floor.
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. 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 gemäß den Druckschriften EP 0 698 162 Bl sowie EP 0 855 482 Bl erwünscht, zwei Paneele, die mit ihren Querseiten aneinandergrenzen und die mit ihren Längsseiten mit einem dritten Paneel verbunden sind, zusammenschieben zu können, um so eine geschlossene Oberfläche zu erhalten.In order to be able to avoid gluing, a plug-in profile for a panel is known from publication WO 96/27721, which initially comprises tongue and groove in a known manner. In addition, each spring has at least one continuous nose on an upper and / or lower side. Each groove is provided with grooves so that the nose or noses get into the corresponding groove after two panels have been put together. This creates a positive connection between two panels. The use of glue is not required to assemble panels into a floor or wall covering. If a panel is connected with its long side offset to a long side of a next panel, it may be necessary or useful to be able to move it laterally after the positive connection. Such a lateral shift is desirable, for example, so as to obtain a smooth lateral edge. According to the documents EP 0 698 162 B1 and EP 0 855 482 B1, it is also desirable to be able to push together two panels which adjoin one another with their transverse sides and which are connected with their longitudinal sides to a third panel, so as to obtain a closed surface ,
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 rela- tive Verschiebung parallel zu einer Längsseite durchzuführen.In the prior art, as is known from the publications WO 96/27719 or WO 96/27721, the nose-groove-tongue-and-groove connection extends over the entire long side of two panels. Strong frictional forces have to be overcome in order to subsequently carry out a relative displacement parallel to a long side.
Um solche Reibungskräfte zu vermeiden, wird gemäß der Druckschrift EP 0 698 162 Bl ein Spiel (Δ) zwischen einer Verriegelungsnut und einerIn order to avoid such frictional forces, according to EP 0 698 162 B1 there is a play (Δ) between a locking groove and a
Verriegelungsoberfläche an einem Verriegelungselement vorgesehen.Locking surface provided on a locking element.
Die DE 33 43 601 C2 offenbart leimlos miteinander verbundene Fußbodenbeläge, wobei mittels einer Zunge, die in eine Ausnehmung eingreift, zwei Verbindungskanten von Paneelen verriegelt werden. Ein Profilsteg in Gestalt eines flachen Profilansatzes weist an seinem offenen Ende ein Verriegelungselement auf. Das Verriegelungselement wird von einer Verriegelungsnut an der Unterseite eines benachbarten Paneels aufgenommen.DE 33 43 601 C2 discloses floor coverings bonded to one another without glue, two connecting edges of panels being locked by means of a tongue which engages in a recess. A profile web in the form of a flat profile approach has a locking element at its open end. The locking element is received by a locking groove on the underside of an adjacent panel.
Die Platten werden an ihren Längsseiten durch Drehen um die Längskante zusammengefügt. In einer Ausführungsform ist ferner vorgesehen, eine Verriegelung an den kurzen Querseiten vorzusehen, um so ein Auseinanderdriften der Platten bei Belastung zu vermeiden. Diese Verriegelung wirkt jedoch nur in einer Richtung parallel zur Fußbodenoberfläche sowie senkrecht zur kurzen Verbindungskante .The panels are joined on their long sides by turning them around the long edge. In one embodiment, provision is also made to provide a lock on the short transverse sides, in order to prevent the plates from drifting apart when loaded. However, this locking only works in one direction parallel to the floor surface and perpendicular to the short connecting edge.
Der Erfindung liegt die Aufgabe zugrunde, Paneele bereitzustellen, die leimlos miteinander stabil und schnell an sämtlichen Seiten verbunden werden können.The invention has for its object to provide panels that can be stably and quickly connected on all sides with no glue.
Die Aufgabe wird mit Hilfe eines Paneels mit den Merkmalen des ersten Anspruchs gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The object is achieved with the aid of a panel with the features of the first claim. Advantageous refinements result from the subclaims.
Ein Paneel weist mechanische Kupplungsmittel seitlich so auf, dass Paneele leimlos miteinander verbunden werden können. Ein anspruchsgemäßes Paneel umfasst solche Mittel an den Längs- oder Querseiten, dass zwei Paneele hierüber formschlüssig miteinander verbunden werden können. Die Fuge bzw. Kante, die dann durch die beiden Paneele gebildet wird, wird im folgenden Verbindungsfuge oder Verbindungskante genannt. 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 ohne Kraftaufwand verschoben werden können. Es ist jedoch noch möglich, ein Paneel zum Beispiel um die Verbindungsfuge zu drehen und so zwei Paneele voneinander z 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 has mechanical coupling means on the side so that panels can be connected to one another without glue. A panel according to the claim comprises such means on the longitudinal or transverse sides that two panels can be connected to one another in a form-fitting manner. The joint or edge, which is then formed by the two panels, is called the connecting joint or connecting edge in the following. A A positive connection within the meaning of the claim exists if two panels assembled to form a flat surface can only be moved parallel to the connecting joint, but not perpendicularly to them, without force, due to the positive locking within the plane. However, it is still possible to turn a panel around the connection joint, for example, and thus separate two panels from each other. During this movement, a panel leaves the aforementioned level. A shift that does not leave the plane does not take place with such a rotary movement.
Alternativ kann es möglich sein, ein erstes Paneel relativ zum zweiten anzuheben und unter Anwendung von Kraft voneinander zu lösen. Kraft muss im Sinne derAlternatively, it may be possible to lift a first panel relative to the second and release it from one another using force. Power must be in the sense of
Erfindung aufgewendet werden, wenn das zweite Paneel in seiner Position festgehalten werden muss, um ein Ausrasten von Kupplungselementen und damit das Lösen zu bewerkstelligen.Invention are used when the second panel has to be held in position in order to disengage coupling elements and thus to release them.
Wenigstens eine formschlüssige Verbindung ist bevorzugt wie folgt beschaffen. Ein Paneel weist an seiner Unterseite eine hervorstehende Lippe oder Flanke auf. Die Lippe oder Flanke umfasst eine erste Vertiefung zum Beispiel in Form einer Nut. Die erste Vertiefung ist offen zugänglich, wenn das Paneel mit seiner Unterseite auf einem Boden liegt oder an eine Wand gelehnt ist. Ein weiteres Paneel weist an seiner Oberseite eine hervorstehende Lippe oder Flanke auf. An der Unterseite dieser hervorstehenden Lippe oder Flanke steht ein erstes Verriegelungselement zum Beispiel in Form einer Nase oder Feder hervor. Die bisher in diesem Absatz genannten Kupplungsmittel (hervorstehende Flanken sowie erste Vertiefung und erstes Verriegelungselement) sind so aufeinander abgestimmt, dass das erste Verriegelungselement in die erste Vertiefung so gebracht werden kann, dass hierdurch eine mechanische Verbindung parallel zur Oberfläche der Paneele sowie senkrecht zur Verbindungskante bewirkt wird. Die bisher in diesem Absatz genannten Kupplungselemente (hervorstehende Flanken sowie erste Vertiefung und erstes Verriegelungselement) umfassen eine zweite Vertiefung und eine zweites vorstehendesAt least one positive connection is preferably as follows. A panel has a protruding lip or flank on its underside. The lip or flank comprises a first depression, for example in the form of a groove. The first recess is openly accessible if the underside of the panel lies on a floor or is leaning against a wall. Another panel has a protruding lip or flank on its top. On the underside of this protruding lip or flank, a first locking element protrudes, for example in the form of a nose or spring. The coupling means mentioned so far in this paragraph (protruding flanks and the first recess and the first locking element) are matched to one another such that the first locking element can be brought into the first recess in such a way that a mechanical connection is thereby effected parallel to the surface of the panels and perpendicular to the connecting edge. The coupling elements previously mentioned in this paragraph (protruding flanks and first recess and first locking element) comprise a second recess and a second protruding one
Verriegelungselement. Das zweite Verriegelungselement rastet in die zweite Vertiefung ein, wenn das erste Verriegelungselement in die erste Vertiefung gebracht ist. Die Kupplungselemente sind hinreichend elastisch ausgestaltet, um das Einrasten zu ermöglichen. Durch das Einrasten wird eine mechanische Verbindung der Paneele senkrecht zur Oberfläche der Paneele bewirkt. Nach dem Einrasten sind zwei Paneele im Sinne der Erfindung leimlos miteinander verbunden.Locking element. The second locking element snaps into the second recess when the first locking element is brought into the first recess. The coupling elements are designed to be sufficiently elastic to enable them to snap into place. A mechanical connection of the panels perpendicular to the surface of the panels is brought about by the engagement. After snapping in, two panels are glued together without glue in the sense of the invention.
Die vorgenannte leimlose Verbindung kann so beschaffen sein, dass ein kleines Spiel in der Größenordnung von einigen 1/100 oder einigen 1/10 Millimetern zwischen Kupplungselementen so verbleibt, dass zwei Paneele relativ lose miteinander mechanisch verbunden sind. Das Spiel wird sich dann bei der Verbindungsfuge bemerkbar machen. Bevorzugt sind die Kupplungselemente jedoch so aufeinander abgestimmt, dass die Paneele fest miteinander verbunden sind,- ohne dass dabei ein Spiel verbleibt.The aforementioned glue-free connection can be such that a small play of the order of a few 1/100 or a few 1/10 millimeters remains between coupling elements such that two panels are mechanically connected to one another relatively loosely. The game will then make itself felt in the connecting joint. However, the coupling elements are preferably matched to one another in such a way that the panels are firmly connected to one another, without any play remaining.
Um das Einfügen des ersten Verriegelungselementes in die erste Vertiefung zu vereinfachen, verjüngt sich das erste Verriegelungselement zu seinem offenen Ende hin und/ oder die Vertiefung weist einen trichterartigen Einlass auf.In order to simplify the insertion of the first locking element into the first recess, this tapers first locking element towards its open end and / or the recess has a funnel-like inlet.
In einer weiteren vorteilhaften Ausgestaltung derIn a further advantageous embodiment of the
Erfindung weist die hervorstehende Flanke oder Lippe, die an der Unterseite eines Paneels vorgesehen ist, eine Schräge auf, die einer Rampe ähnelt. Ergänzend oder alternativ ist unterhalb der Flanke oder Lippe, die an der Oberseite eines Paneels vorgesehen ist, eine Schräge vorgesehen, die mit der Unterseite der zugehörigen Flanke oder Lippe einen Winkel größer als 90° einschließt. Durch die vorgenannten Schrägen wird das Verbinden zweier Paneele weiter vereinfacht.Invention has the protruding flank or lip, which is provided on the underside of a panel, a slope that resembles a ramp. In addition or alternatively, a slope is provided below the flank or lip, which is provided on the top of a panel, which forms an angle greater than 90 ° with the underside of the associated flank or lip. The aforementioned bevels further simplify the connection of two panels.
Um die oben genannte Elastizität zu verwirklichen, weist das erste Verriegelungselement an seinem offenen Ende einen oder mehrere Einschnitte oder eingefräste Rillen auf. Das erste Verriegelungselement kann dann an seinem offenen Ende etwas zusammengedrückt werden, um so das zweite Verriegelungselement in die zweite Vertiefung bringen zu können.In order to achieve the above-mentioned elasticity, the first locking element has one or more incisions or milled grooves at its open end. The first locking element can then be slightly compressed at its open end so that the second locking element can be brought into the second recess.
Bevorzugt sind die vorgenannten Kupplungselemente so beschaffen, dass die Unterseite einer hervorstehenden Lippe oder Flanke eines Paneels an wenigstens einer Stelle auf der Oberseite einer hervorstehenden Lippe oder Flanke eines weiteren Paneels aufliegt, wenn die beiden Paneele miteinander verbunden sind. Unter anderem hierdurch wird eine feste leimlose Verbindung zwischen zwei Paneelen sichergestellt. Unterseite und Oberseite sind in diesem Zusammenhang weit auszulegen. Es genügt, wenn die Auflage mittels des ersten Verriegelungselementes und mittels der ersten Vertiefung bereitgestellt wird.The aforementioned coupling elements are preferably designed such that the underside of a protruding lip or flank of a panel rests at least at one point on the top of a protruding lip or flank of a further panel when the two panels are connected to one another. Among other things, this ensures a firm glue-free connection between two panels. The underside and top side are to be interpreted broadly in this context. It is sufficient if the edition by means of the first Locking element and is provided by means of the first recess.
In einer vorteilhaften Ausgestaltung der Erfindung verbleiben zwischen den Kupplungselementen von zwei miteinander verbunden Paneelen Zwischenräume an denIn an advantageous embodiment of the invention, spaces remain between the coupling elements of two interconnected panels
Stellen, die nicht der mechanischen Verbindung dienen.Places that are not used for mechanical connection.
Hierdurch wird das Verbinden weiter vereinfacht.This further simplifies the connection.
Ungenauigkeiten bei der Herstellung der Kupplungselemente können außerdem leichter kompensiert werden.Inaccuracies in the manufacture of the coupling elements can also be compensated for more easily.
In einer weiteren vorteilhaften Ausgestaltung der Erfindung weist das erste hervorstehende Verriegelungselement das zweite hervorstehendeIn a further advantageous embodiment of the invention, the first protruding locking element has the second protruding
Verriegelungselement an der Seite auf, die zusammen mit- dem zugehörigen Paneel eine Ausnehmung bildet.Locking element on the side that forms a recess together with the associated panel.
Wie einem der nachfolgenden Ausführungsbeispiele zu entnehmen ist, können weiter Kupplungselemente in Form von hervorstehenden Verriegelungselementen vorgesehen sein, die in eine Vertiefung in einem weiteren Paneel einrastet, um so eine mechanische Verriegelung senkrecht zur Oberfläche der Paneele zu schaffen. Auf diese Weise kann die Verbindung weiter gefestigt werden.As can be seen from one of the following exemplary embodiments, coupling elements in the form of protruding locking elements can also be provided, which snap into a recess in a further panel in order to create a mechanical locking perpendicular to the surface of the panels. In this way, the connection can be further strengthened.
Mit Hilfe der anspruchsgemäßen Kupplungselemente können Paneele schneller verbunden werden im Vergleich zum Stand der Technik, der ein Verschieben von zwei bereits mit einem dritten Paneel verbundenen Paneelen erfordert. Zu diesem Zweck weisen Paneele entweder Kupplungselemente der anspruchsgemäßen Art an sämtlichen Seiten auf oder an einer Seite sind Kupplungselemente vorgesehen, die über eine Drehbewegung verbunden werden. Im ersten Fall genügt eine Absenkbewegung, um ein Paneel zeitgleich an zwei Seiten mit bereits verlegten Paneelen zu verbinden. Im zweiten Fall wird die Drehbewegung quasi mit der Absenkbewegung kombiniert. Zwei Paneele werden zum Beispiel an den Längsseiten über eine Drehbewegung um die gemeinsame Kante herum miteinander verbunden. Zugleich ist es möglich, ein drittes Paneel an derWith the help of the coupling elements according to the claims, panels can be connected more quickly compared to the prior art, which requires the displacement of two panels already connected to a third panel. For this purpose, panels either have coupling elements of the type claimed Coupling elements are provided on all sides on or on one side and are connected via a rotary movement. In the first case, a lowering movement is sufficient to simultaneously connect a panel on two sides with already installed panels. In the second case, the rotary movement is combined with the lowering movement. For example, two panels are connected to each other on the long sides by rotating around the common edge. It is also possible to have a third panel on the
Schmalseite bzw. Querseite mit dem Paneel zu verbinden, welches gedreht wird, da die Drehbewegung zugleich relativ zu diesem dritten Paneel eine Art Absenkbewegung darstellt. Ein Verschieben wie beim Stand der Technik entfällt. Hierdurch vereinfacht und beschleunigt sich der Vorgang des mechanischen Verbindens .To connect the narrow side or transverse side to the panel, which is rotated, since the rotational movement at the same time represents a kind of lowering movement relative to this third panel. There is no shifting as in the prior art. This simplifies and speeds up the process of mechanical connection.
Kupplungselemente, die über eine Drehbewegung miteinander verbunden werden, sind bevorzugt wie folgt beschaffen.Coupling elements which are connected to one another via a rotary movement are preferably designed as follows.
Ein Paneel weist zum Beispiel an den Längsseiten wenigstens eine seitlich eingefräste Nut auf, die durch zwei Flanken oder Schenkel gebildet wird. Die eineA panel has, for example, on the long sides at least one laterally milled groove, which is formed by two flanks or legs. The one
Flanke ragt über die andere hinaus, ist also länger als die andere. Beide Flanken sind vorzugsweise 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.Flank extends beyond the other, so it is longer than the other. Both flanks are preferably rigid, that is to say essentially not elastic. A flank is rigid in the sense of the invention if, in contrast to the teaching according to document WO 97/47834, it cannot be bent elastically in such a way that it is possible to join together by pushing two panels together in one plane is. At least one recess is provided in the longer flank.
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 tongue on the side which is inserted into the aforementioned groove in order to connect two panels to one another. The spring has at least one protruding nose on its lower or upper side, which comes into the aforementioned recess of the flank when the two panels are joined together. The nose then reaches the 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 Pa- neele durch die Drehbewegung miteinander zu verbinden. Die Feder wird also durch eine Drehbewegung in die korrespondierende Nut eines benachbarten Paneels hineinbe- wegt, ohne dass die Flanke mit der Ausnehmung stark gebogen werden müsste.The tongue is designed so that on one side (bottom or top), at least in the region of its open end, it is at a distance from the adjacent flank of the groove when the tongue has been brought into the corresponding groove. There is then a gap between the affected top or bottom of the spring and the adjacent flank. This 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 tapers in this area similarly to a tip. The affected bottom or top is the side that borders on the flank with the recess. This incline or the space provided makes it possible to detach a panel from another panel without much effort by rotating around the connecting joint of two panels, or vice versa to connect two panels to one another by means of the rotating movement. The tongue is thus rotated into the corresponding groove of an adjacent panel. moves without the flank with the recess having to be strongly bent.
Eine solche Drehbewegung ist zwar aus der Druckschrift EP 0855482 Bl 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 known from EP 0855482 B1. However, it is not known from this to provide a space by providing, for example, the above-mentioned bevel in a spring, in order to avoid bending 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 rigidly design the flanks of the lateral groove in a panel. The positive connection between two panels is 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 er- forderlich, 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 in order to compensate so that the spring in the area of the slope no longer borders on the flank as in the prior art. This is because such a contact surface is required so that one surface of a panel cannot be lowered compared to an adjacent panel surface as a result of a load.
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. 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. Bei- spielsweise könnte es sich bei der Ausnehmung um einThe nose contacts another side of a side wall of the recess when two panels are joined together. It is the side or wall through which a locking (parallel to the surface of the panels) is brought about between two panels. This contact is necessary so that the panels are firmly connected. In this way it can be ensured that the connecting joint between the two panels then has no gap. The recess in the flank of the groove is in particular in the form of a groove which runs parallel to the adjacent connecting joint between two panels. A recess can of course also have other shapes. For example, the recess could be a
Langloch handeln, in das die korrespondierende Nase eines weiteren Paneels einrasten kann.Act an elongated hole into which the corresponding nose of another panel can snap.
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 Funk- tion 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, a gap or play is provided between the side of the spring that has the bevel and the protruding flank. This further facilitates the joining of two panels. A gap can be provided since the nose contacts the bottom of the recess and takes over the function of the contact between tongue and groove that is usually provided. The gap or play between the tongue and the groove can be limited to a few hundredths of a millimeter, for example 3/100 mm as the preferred lower limit.
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 An- spruchs 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 unter Anwendung von Kraft hochzuheben oder um eine Verbindungsfuge zu drehen und so Paneele voneinander zu lösen. Bei der Drehbewegung verlässt ein Paneel die vorgenannte Ebene und wird zugleich relativ zu einem seitlich angrenzenden, verlegten Paneel angehoben. Eine Verschiebung, bei der die Ebene nicht verlassen wird, findet bei einer solchen Drehbewegung also nicht statt.A panel according to the claim thus comprises means on the longitudinal and / or transverse sides such that two panels can be connected to one another in a form-fitting manner. A positive connection in the sense of the claim exists if two panels assembled to form a flat surface can only be moved parallel to the connecting joint, but not perpendicularly to it, due to the positive connection within the plane. However, it is still possible to lift a panel using force or to turn a connecting joint to separate panels. When rotating, a panel leaves the aforementioned level and at the same time becomes relative to one laterally adjacent, installed panel raised. A shift that does not leave the plane does not take place with such a rotary movement.
Die Erfindung wird anhand der nachfolgenden Figuren 1 bis 5 näher verdeutlicht.The invention is illustrated in more detail in the following FIGS. 1 to 5.
Paneele 1 und 2 weisen gemäß den Figuren 1 bis 5 mechanische Kupplungsmittel seitlich so auf, dassAccording to FIGS. 1 to 5, panels 1 and 2 have mechanical coupling means on the side in such a way that
Paneele 1, 2 und 3 leimlos miteinander verbunden werden können. Jedes Paneel 1, 2 und 3 umfasst solche Mittel an den Längs- oder Querseiten, dass Paneele hierüber formschlüssig miteinander verbunden werden können. Die Fuge bzw. Kante 3 bzw. 20, die dann durch zwei Paneele gebildet wird, ist die Verbindungsfuge oder Verbindungskante. Die zu einer ebenen Fläche zusammengesetzte Paneele 1 , 2 und 3 können aufgrund von Formschluss innerhalb der Ebene allenfalls noch parallel zur Verbindungsfuge 3 bzw. 20, nicht aber senkrecht hierzu ohne Kraftaufwand verschoben werden. Bei der Parallelverschiebung relativ zur Verbindungsfuge muss Kraft aufgewendet werden, wenn eine entsprechende Reibung überwunden werden muss. Dies ist bei den gezeigten Beispielen der Fall. Es ist möglich, ein Paneel 2 gegenüber dem Paneel 1 gemäß den Figuren 1 bis 4 anzuheben, um so dass Paneel 1 vom Paneel 2 unter Anwendung von Kraft zu lösen. Dabei wird die formschlüssige Verbindung gelöst. Bei den Kupplungselementen gemäß Figur 5 ist es erforderlich, ein Paneel um die Verbindungsfuge zu drehen, um so die z;wei Paneele 2 und 3 voneinander zu lösen. Eine Verschiebung, bei der die durch die Paneele 1, 2 und 3 gebildete Ebene nicht verlassen wird, findet bei der Hebe- oder Drehbewegung nicht statt.Panels 1, 2 and 3 can be connected without glue. Each panel 1, 2 and 3 comprises such means on the longitudinal or transverse sides that panels can be connected to one another in a positive manner. The joint or edge 3 or 20, which is then formed by two panels, is the connecting joint or connecting edge. The panels 1, 2 and 3 assembled to form a flat surface can at best still be displaced parallel to the connecting joint 3 or 20, but not perpendicularly to them, without any effort, due to positive locking within the plane. With the parallel displacement relative to the connection joint, force must be applied if a corresponding friction has to be overcome. This is the case with the examples shown. It is possible to raise a panel 2 relative to the panel 1 according to FIGS. 1 to 4, so that the panel 1 can be detached from the panel 2 using force. The positive connection is released. In the coupling elements according to FIG. 5, it is necessary to turn a panel around the connecting joint in order to detach the two panels 2 and 3 from one another. A shift where panels 1, 2 and 3 formed level is not exited, does not take place during the lifting or rotating movement.
Das Paneel 1 weist gemäß den Figuren 1 bis 4 an seiner Querseite sowie an seiner Unterseite eine hervorstehende Lippe oder Flanke 4 auf. Die Lippe oder Flanke 4 umfasst eine erste Vertiefung in Form einer Nut 5. Die erste Vertiefung 5 ist offen zugänglich, wenn das Paneel 1 mit seiner Unterseite 6 auf einem Boden liegt oder an einer Wand befestigt ist. Das weitere Paneel 2 weist an seiner Oberseite eine hervorstehende Lippe oder Flanke 7 auf. An der Unterseite dieser hervorstehenden Lippe oder Flanke steht ein erstes Verriegelungselement 8 in Form einer Feder hervor. Die hervorstehende Flanken 4 und 7 sowie die erste Vertiefung 5 und das ersteAccording to FIGS. 1 to 4, the panel 1 has a protruding lip or flank 4 on its transverse side and on its underside. The lip or flank 4 comprises a first depression in the form of a groove 5. The first depression 5 is openly accessible when the underside 6 of the panel 1 lies on a floor or is attached to a wall. The further panel 2 has a protruding lip or flank 7 on its upper side. A first locking element 8 in the form of a spring protrudes from the underside of this protruding lip or flank. The protruding flanks 4 and 7 as well as the first depression 5 and the first
Verriegelungselement 8 sind so aufeinander abgestimmt, dass das erste Verriegelungselement 8 in die erste Vertiefung 5 so gebracht werden kann, dass hierdurch eine mechanische Verbindung parallel zur Oberfläche 9 der Paneele 1 und 2 sowie senkrecht zur Verbindungskante 3 bewirkt wird. Die hervorstehenden Flanken 4 und 7 sowie die erste Vertiefung 5 und das erstes Verriegelungselement 8 umfassen wenigstens eine zweite Vertiefung 10 und eine zweites vorstehendes Verriegelungselement 11. Das zweiteLocking elements 8 are coordinated with one another in such a way that the first locking element 8 can be brought into the first recess 5 such that a mechanical connection is thereby effected parallel to the surface 9 of the panels 1 and 2 and perpendicular to the connecting edge 3. The protruding flanks 4 and 7 as well as the first depression 5 and the first locking element 8 comprise at least a second depression 10 and a second protruding locking element 11. The second
Verriegelungselement 11 rastet in die zweite Vertiefung 10 ein, wenn das erste Verriegelungselement 8 in die erste Vertiefung 5 gebracht ist. Diese Kupplungselemente sind hinreichend elastisch ausgestaltet, um das Einbringen des ersten Verriegelungselementes 8 in die erste Vertiefung 5 sowie das Einrasten von dem zweiten Verriegelungselement 11 in die zweite Vertiefung 10 zu ermöglichen, ohne dass die Kupplungselemente geschädigt werden. Durch das Einrasten wird eine mechanische Verbindung der Paneele senkrecht zur Oberfläche 9 der Paneele 1 und 2 bewirkt. Nach dem Einrasten sind die zwei Paneele 1 und 2 im Sinne der Erfindung leimlos miteinander verbunden.Locking element 11 snaps into the second depression 10 when the first locking element 8 is brought into the first depression 5. These coupling elements are designed to be sufficiently elastic to insert the first locking element 8 into the first recess 5 and to engage the second one To enable locking element 11 in the second recess 10 without the coupling elements being damaged. A mechanical connection of the panels perpendicular to the surface 9 of the panels 1 and 2 is brought about by the engagement. After latching, the two panels 1 and 2 are glued together without glue in the sense of the invention.
Die in den Figuren 1 bis 4 gezeigten leimlosen Verbindung sind so beschaffen sein, dass kein Spiel zwischen den Kupplungselementen so verbleibt, dass die zwei Paneele 1 und 2 relativ lose miteinander mechanisch verbunden sind. Ein Spiel tritt bei der Verbindungsfuge 3 nicht auf. Die Kupplungselemente sind also so aufeinander abgestimmt, dass die Paneele 1 und 2 fest im Sinne der Erfindung miteinander verbunden sind.The glue-free connection shown in Figures 1 to 4 are such that there is no play between the coupling elements so that the two panels 1 and 2 are mechanically connected to each other relatively loosely. A game does not occur in the joint 3. The coupling elements are thus matched to one another in such a way that the panels 1 and 2 are firmly connected to one another in the sense of the invention.
Um das Einfügen des ersten Verriegelungselementes 8 in die erste Vertiefung 5 zu vereinfachen, verjüngt sich gemäß den Figuren 1 bis 4 das erste Verriegelungselement 8 zu seinem offenen Ende hin (läuft spitz zu) und die erste Vertiefung 5 weist insbesondere gemäß den Figuren 1 und 2 einen trichterartigen Einlass auf.In order to simplify the insertion of the first locking element 8 into the first recess 5, the first locking element 8 tapers towards its open end (tapers to a point) according to FIGS. 1 to 4 and the first recess 5 points in particular according to FIGS. 1 and 2 a funnel-like inlet.
Gemäß Fig. 3 weist die hervorstehende Flanke oder Lippe 4 , die an der Unterseite 6 des Paneels 1 vorgesehen ist, eine Schräge 12 auf, die einer Rampe ähnelt. Ergänzend oder alternativ ist gemäß den Figuren 1, 3 und 4 unterhalb der Flanke oder Lippe 7 , die an der Oberseite des Paneels 2 vorgesehen ist, eine Schräge 13 vorhanden, die mit der Unterseite der zugehörigen Flanke oder Lippe 7 einen Winkel größer als 90° einschließt. Durch die vorgenannten Schrägen 12 und 13 wird das Verbinden der zwei Paneele 1 und 2 weiter vereinfacht.According to FIG. 3, the protruding flank or lip 4, which is provided on the underside 6 of the panel 1, has a bevel 12 which is similar to a ramp. Additionally or alternatively, according to FIGS. 1, 3 and 4, below the flank or lip 7, which is provided on the top of the panel 2, there is a bevel 13 which is aligned with the bottom of the associated one Flank or lip 7 encloses an angle greater than 90 °. The aforementioned bevels 12 and 13 further simplify the connection of the two panels 1 and 2.
Um die gewünschte genannte Elastizität bei den Kupplungselementen zu verwirklichen, weist das erste Verriegelungselement 8 gemäß den Figuren 2 und 4 an seinem offenen Ende einen Einschnitt 14 auf. Das erste Verriegelungselement 8 kann dann an seinem offenen Ende etwas zusammengedrückt werden, um so das zweite Verriegelungselement 11 in die zweite Vertiefung 10 zu bringen.In order to achieve the desired elasticity in the coupling elements, the first locking element 8 according to FIGS. 2 and 4 has an incision 14 at its open end. The first locking element 8 can then be slightly compressed at its open end so as to bring the second locking element 11 into the second recess 10.
Die Kupplungselemente gemäß den Figuren 1 bis 4 sind so beschaffen, dass die Unterseite der hervorstehenden Lippe oder Flanke 7 des Paneels 2 an wenigstens einer Stelle auf der Oberseite der hervorstehenden Lippe oder Flanke 4 des Paneels 1 aufliegt, wenn die beiden Paneele miteinander verbunden sind. Unter anderem hierdurch wird die feste leimlose Verbindung zwischen den zwei Paneelen sichergestellt. Es genügt, wenn die Auflage - wie in Figur 3 gezeigt - ausschließlich mittels des ersten Verriegelungselementes 8 und mittels der ersten Vertiefung 8 bewirkt wird.The coupling elements according to FIGS. 1 to 4 are designed such that the underside of the protruding lip or flank 7 of the panel 2 rests at least at one point on the top of the protruding lip or flank 4 of the panel 1 when the two panels are connected to one another. This ensures, among other things, the firm glueless connection between the two panels. It is sufficient if the support - as shown in FIG. 3 - is effected exclusively by means of the first locking element 8 and by means of the first recess 8.
Zwischen den Kupplungselementen der zwei miteinander verbunden Paneele 1 und 2 verbleiben gemäß den Figuren 1 bis 4 Zwischenräume an den Stellen, die nicht der mechanischen formschlüssigen Verbindung dienen. Hierdurch wird das Verbinden vereinfacht. Ungenauigkeiten bei der Herstellung der Kupplungselemente können leicht kompensiert werden. Gemäß den Figuren 1 bis 4 weist das erste hervorstehende Verriegelungselement 8 das zweite hervorstehende Verriegelungselement 11 an der Seite auf, die zusammen mit dem zugehörigen Paneel 2 eine Ausnehmung 15 bildet.According to FIGS. 1 to 4, spaces remain between the coupling elements of the two panels 1 and 2 which are connected to one another at those points which are not used for the mechanical positive connection. This simplifies the connection. Inaccuracies in the manufacture of the coupling elements can easily be compensated for. According to FIGS. 1 to 4, the first protruding locking element 8 has the second protruding locking element 11 on the side which, together with the associated panel 2, forms a recess 15.
Zusätzliche Kupplungselemente in Form von einem hervorstehenden Verriegelungselement 16, das in eine nächste Vertiefung 17 in dem Paneel 1 einrastet, um so eine mechanische Verriegelung senkrecht zur Oberfläche der Paneele zu schaffen, werden in der Figur 4 gezeigt. Auf diese Weise kann die formschlüssige Verbindung weiter gefestigt werden.Additional coupling elements in the form of a protruding locking element 16, which snaps into a next recess 17 in the panel 1, so as to create a mechanical locking perpendicular to the surface of the panels, are shown in FIG. In this way, the positive connection can be further strengthened.
Mit Hilfe der in den Figuren 1 bis 4 gezeigten Kupplungselemente können Paneele schneller verbunden werden im Vergleich zum Stand der Technik, der ein Verschieben von zwei bereits mit einem dritten Paneel verbundenen Paneelen erfordert. Zu diesem Zweck weisen Paneele entweder Kupplungselemente der in den Figuren 1 bis 4 gezeigten Art an sämtlichen Seiten auf oder an einer Seite (insbesondere an der Längsseite) sind Kupplungselemente - wie in Figur 5 gezeigt - vorgesehen, die über eine Drehbewegung verbunden werden. Im ersten Fall genügt eine Absenkbewegung, um ein Paneel 2 zeitgleich an zwei Seiten mit bereits verlegten Paneelen zu verbinden. Im zweiten Fall wird die Drehbewegung zwischen zwei Paneelen 2 und 3 quasi mit der Absenkbewegung zwischen zwei Paneelen 1 und 2 kombiniert. Zwei Paneele 2 und 3 werden zum Beispiel an den Längsseiten gemäß Figur 5 über eine Drehbewegung um die gemeinsame Kante 20 herum miteinander verbunden. Zugleich ist es möglich, ein das Paneel 1 an der Schmalseite bzw. Querseite mit dem Paneel 2 zu verbinden, da die Drehbewegung zugleich relativ zu dem Paneel 1 eine Art Absenkbewegung darstellt. Ein Verschieben wie beim Stand der Technik entfällt.With the aid of the coupling elements shown in FIGS. 1 to 4, panels can be connected more quickly compared to the prior art, which requires the displacement of two panels already connected to a third panel. For this purpose, panels either have coupling elements of the type shown in FIGS. 1 to 4 on all sides or on one side (in particular on the long side) coupling elements are provided, as shown in FIG. 5, which are connected by means of a rotary movement. In the first case, a lowering movement is sufficient to simultaneously connect a panel 2 on two sides to panels that have already been laid. In the second case, the rotary movement between two panels 2 and 3 is quasi combined with the lowering movement between two panels 1 and 2. For example, two panels 2 and 3 are connected to one another on the long sides according to FIG. 5 by means of a rotary movement around the common edge 20. At the same time, it is possible to connect the panel 1 to the panel 2 on the narrow side or transverse side, since the rotary movement at the same time represents a kind of lowering movement relative to the panel 1. There is no shifting as in the prior art.
Hierdurch vereinfacht und beschleunigt sich der Vorgang des mechanischen Verbindens.This simplifies and speeds up the process of mechanical connection.
Fig. 5 zeigt einen Schnitt durch zwei miteinander form- schlüssig im Sinne der Erfindung verbundene Paneele 2 und 3. Paneel 3 weist an einer Längsseite eine Nut 18 auf. An einer Längsseite des Paneels 2 ist eine Feder 19 vorgesehen. Die Feder 19 ist in die Nut 18 hineingedreht worden und befindet sich also in der Nut 18. Die Verbindungsfuge 20 diente bei der Drehung als Drehachse. Bei der Verbindungsfuge 20 handelt es sich um die Fuge, die sich zwischen den beiden Paneelen 2 und 3 befindet. Die Längsseite des Paneels 3 weist eine vorstehende untere Flanke 21 auf. Diese untere Flanke 21 ist an der langen Seite starr im Sinne der5 shows a section through two panels 2 and 3 which are connected to one another in a form-fitting manner in the sense of the invention. Panel 3 has a groove 18 on one long side. A spring 19 is provided on one long side of the panel 2. The spring 19 has been screwed into the groove 18 and is therefore located in the groove 18. The connecting joint 20 served as the axis of rotation during the rotation. The connecting joint 20 is the joint that is located between the two panels 2 and 3. The long side of the panel 3 has a projecting lower flank 21. This lower flank 21 is rigid on the long side in the sense of
Erfindung, da es nicht möglich ist, diese hinreichend elastisch nach unten zu drücken, um so die Feder 19 von Paneel 2 in die Nut 18 durch eine Bewegung in einer Ebene hineinschieben zu können. In die untere Flanke 21 ist als Ausnehmung eine Rille 22 im wesentlichen senkrecht von oben eingefräst worden. Die Rille 22 erstreckt sich über die gesamte Längsseite des Paneels 3. Paneel 2 weist unterhalb der Feder 19 eine Nase bzw. ein hervorstehendes Verriegelungselement 23 auf. In der Fig. 5 wird gezeigt, in welcher Weise eine Nase 23 in die Rille 22 hineinragt. Die Position der Nase 23 ist so auf die Rille 22 abgestimmt, dass das Paneel 3 mit dem Paneel 2 auf der Oberseite 9 der Paneelen dicht abschließt. Es verbleibt also kein Spalt an der Oberfläche bei der Verbindungsfuge 20. Soweit es für die Sicherstellung einer geschlossenen Oberfläche 9 nicht erforderlich ist, ist zwischen der Nase 23 und der Rille 22 ein Spalt 24 vorgesehen. Probleme aufgrund von Fertigungstoleranzen werden so vermieden. Ferner wird die Handhabung beim Verbinden zweier Paneele vereinfacht. Die Feder 19 weist an ihrer Unterseite eine Schräge 25 auf. An dieser Unterseite läuft die Feder 19 also spitz zu. Die Schräge 25 ist vorgesehen, um die Feder 19 in die Nut 18 durch eine Drehbewegung störungsfrei hineindrehen zu können, ohne den starren Schenkel 21 bzw. die untere starre Flanke 21 merklich nach unten biegen zu müssen. Das Ende der Feder 19 ragt nicht vollständig in die Nut 18 hinein, so dass ein Spalt verbleibt. Probleme, die sich aus Fertigungsungenauigkeiten ergeben können, werden durch Vorsehen dieses Spaltes vermieden. Die Oberseite der Nut 18 mündet nach außen in eine Schräge 26 ein. Hierdurch verbleibt an dieser Stelle ebenfalls ein Spalt zwischen den beiden Paneelen 2 und 3. Durch Vorsehen der Schräge 26 wird weiterer Raum bereitgestellt, der für das Hineindrehen der Feder 19 in die Nut 18 erforderlich ist.Invention, since it is not possible to press them down sufficiently elastically so that the tongue 19 of panel 2 can be pushed into the groove 18 by movement in one plane. In the lower flank 21, a groove 22 has been milled substantially vertically from above as a recess. The groove 22 extends over the entire longitudinal side of the panel 3. Panel 2 has a nose or a protruding locking element 23 below the spring 19. 5 shows the manner in which a nose 23 projects into the groove 22. The position of the nose 23 is matched to the groove 22 such that the panel 3 is sealed with the panel 2 on the top 9 of the panels concludes. There is therefore no gap on the surface at the connecting joint 20. As far as it is not necessary to ensure a closed surface 9, a gap 24 is provided between the nose 23 and the groove 22. This avoids problems due to manufacturing tolerances. Furthermore, the handling when connecting two panels is simplified. The spring 19 has a bevel 25 on its underside. The spring 19 thus tapers on this underside. The bevel 25 is provided in order to be able to rotate the tongue 19 into the groove 18 without disturbance by a rotary movement without having to bend the rigid leg 21 or the lower rigid flank 21 appreciably downwards. The end of the tongue 19 does not protrude completely into the groove 18, so that a gap remains. Problems that can arise from manufacturing inaccuracies are avoided by providing this gap. The top of the groove 18 opens out into a slope 26. As a result, a gap between the two panels 2 and 3 also remains at this point. By providing the bevel 26, additional space is provided which is required for the tongue 19 to be screwed into the groove 18.
Die Nase 23 reicht bis zum Boden der Rille 22 und dient als Auflage . Insbesondere deshalb kann ein Spalt 27 zwischen der Unterseite der Feder 19 und der darunter befindlichen Wand der Nut 18 verbleiben. The nose 23 extends to the bottom of the groove 22 and serves as a support. In particular, therefore, a gap 27 may remain between the underside of the spring 19 and the wall of the groove 18 located underneath.
