Description

Die Erfindung betrifft Paneele, die ohne Leim miteinander verbunden werden können. Die Paneele werden mit einem schnur- oder stabartigen Element - im folgenden Schnur genannt - umrandet. Die mit der Schnur umrandeten, verlegten Paneele bilden einen Belag für einen Fußboden, eine Wand oder eine Decke. Im verlegten Zustand der Paneele ist die Schnur auf der Oberfläche sichtbar. Solche Paneele sind aus der Druckschrift DE 202 05 774 U1 bekanntThe invention relates to panels that can be connected together without glue. The panels are bordered with a cord or rod-like element - called a cord below. The stringed, laid panels form a covering for a floor, wall or ceiling. In laid condition of panels the cord on a surface is visible. Such panels are from the document DE 202 05 774 U1 known

Aus der GB 812,671 ist ein Paneelsystem vorbekannt, bei dem ein Spalt zwischen zwei zusammengefügten Paneelen mittels eines Dichtstreifens abgedichtet ist. Der Dichtstreifen verbreitet sich im Querschnitt von oben nach unten, um einen sicheren Sitz zu gewährleisten.From the GB 812,671 a panel system is previously known in which a gap between two joined panels is sealed by means of a sealing strip. The sealing strip spreads in cross section from top to bottom to ensure a secure fit.

Aus Dokument WO 03/087497 A1 ist ein Paneelsystem nach dem Oberbegriff des Anspruchs 1 bekannt. Das bekannte Paneelsystem umfasst eine Paneelschnur, die einen Spalt zwischen zwei zusammengefügten Paneelen abdichtet. Die Paneelschnur weist ebenfalls einen sich von oben nach unten verbreitenden Querschnitt auf, hat jedoch den Nachteil, dass sie sich beim Verlegen aus ihrer Position lösen kann, sofern sie nicht durch andere Befestigungsmittel, wie zum Beispiel durch Verkleben, in ihrer Position gehalten ist.From document WO 03/087497 A1 a panel system according to the preamble of claim 1 is known. The known panel system comprises a panel cord which seals a gap between two joined panels. The panel cord also has a top-to-bottom spreading cross-section but has the disadvantage of being able to dislodge from its position during installation, unless it is held in place by other fastening means, such as by gluing.

Um die bekannten Paneele nebst Schnur zu verlegen, muss entweder ein zusätzliches Werkzeug verwendet werden oder aber die Schnur muss mit Kraft abschließend in einen verbleibenden Spalt zwischen zwei Paneele hinein gedrückt werden. Es hat sich in der Praxis gezeigt, dass das Verlegen solcher Paneele nebst Umrandung relativ umständlich ist.To lay the known panels together with string, either an additional tool must be used or the string must be pressed with force finally into a remaining gap between two panels. It has been shown in practice that the laying of such panels together with border is relatively cumbersome.

Demgegenüber ist es Aufgabe der Erfindung, Paneele mit einer Umrandung bereitzustellen, die vergleichsweise einfach verlegt werden können.In contrast, it is an object of the invention to provide panels with a border, which can be installed relatively easily.

Die Aufgabe der Erfindung wird durch ein Paneelsystem gelöst, das die Merkmale des ersten Anspruchs aufweist. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The object of the invention is achieved by a panel system having the features of the first claim. Advantageous embodiments emerge from the subclaims.

Die Paneele sind so beschaffen, dass diese ohne Lelm miteinander verbunden werden können. Dies bedeutet, dass die Paneele solche Kupplungselemente aufwelsen, dass zwei miteinander verbundene Paneele durch Formschluss senkrecht zur gemeinsamen Oberfläche sowie parallel zur gemeinsamen Oberfläche und zugleich senkrecht zur gemeinsamen Fuge gekoppelt sind. In diesem Zustand verbleibt an der Oberfläche ein Spalt für die Aufnahme einer Schnur. Die Kupplungselemente umfassen eine Feder, die bei einem Paneel seitlich hervor steht. Für das Verlegen wird die Schnur auf der Oberseite der Feder abgelegt. Anschließend werden die beiden Paneele miteinander gekoppelt. Nach der Kopplung befindet sich die Schnur in dem vorgenannten Spalt. Die Praxis hat gezeigt, dass auf diese Weise das Verlegen sehr viel einfacher und schneller möglich ist im Vergleich zum eingangs genannten Stand der Technik.The panels are designed so that they can be connected together without a helmet. This means that the panels such coupling elements aufelsen that two interconnected panels are coupled by positive engagement perpendicular to the common surface and parallel to the common surface and at the same time perpendicular to the common joint. In this state remains on the surface a gap for receiving a string. The coupling elements comprise a spring, which protrudes laterally at a panel. For laying the cord is placed on top of the spring. Subsequently, the two panels are coupled together. After the coupling, the cord is in the aforementioned gap. Practice has shown that laying in this way is much easier and faster possible compared to the aforementioned prior art.

Um Fehler während des Verlegens zu vermeiden, weist die Unterseite der Schnur sowie die Oberseite der Feder bevorzugt aneinander angepasste Flächen auf. Dies erleichtert das richtige Ablegen der Schnur auf der Oberseite der Feder. So weist beispielsweise die Feder besonders bevorzugt eine ebene, glatte Fläche auf, die parallel zur Oberfläche des Paneel verläuft. Die Unterseite der Schnur bildet dann ebenfalls eine ebene, glatte Fläche. Wird die Schnur nun mit der Unterseite auf der Oberfläche der Feder abgelegt, so wird so ein unerwünschtes Verdrehen der Schnur zuverlässig vermieden.To avoid mistakes during installation, the underside of the cord and the upper side of the spring preferably have mating surfaces. This facilitates the proper placement of the cord on top of the spring. For example, the spring particularly preferably has a flat, smooth surface which runs parallel to the surface of the panel. The underside of the cord then also forms a flat, smooth surface. If the cord is now placed on the underside of the surface of the spring, so an undesirable twisting the cord is reliably avoided.

Um die Schnur zuverlässig in der richtigen Lage auf der Oberseite der Feder abzulegen, verbreitert sich die Schnur nach unten zu ihrer Unterseite hin. Die Auflagefläche der Schnur auf der Oberfläche der Feder wird so vergrößert. Dies sichert eine stabile Lage der Schnur auf der Oberfläche der Feder während des Verlegens.In order to place the cord reliably in the correct position on the top of the spring, the cord widens down towards its bottom. The contact surface of the cord on the surface of the spring is thus increased. This ensures a stable position of the cord on the surface of the spring during laying.

Gemäß der Erfindung weist das Paneel mit der Feder oberhalb der Feder seltlich eine Nut auf. Die Schnur weist seitlich eine korrespondierende Lippe auf, die im verlegten Zustand in die vorgenannte Nut hinein reicht. Für das Verlegen wird die Lippe der Schnur in die Nut, die oberhalb der Feder angeordnet ist, gebracht. Auf diese Weise wird die Schnur weiter verbessert In der richtigen Lage gehalten, wenn ein erstes Paneel anschließend mit einem zweiten Paneel gekoppelt wird. Dies ist vor allem von Interesse, wenn die Paneele einen Belag für eine Decke oder eine Wand bilden. So kann vermieden werden, dass eine Schnur während des Verlegens auf den Boden fällt.According to the invention, the panel with the spring above the spring has a groove. The string has laterally a corresponding lip which extends in the laid state into the aforementioned groove. For laying the lip of the string is placed in the groove, which is located above the spring. In this way, the cord is further improved In the correct position held when a first panel is then coupled to a second panel. This is of particular interest when the panels form a covering for a ceiling or a wall. This will prevent a string from falling to the floor during laying.

Bevorzugt grenzt die Lippe an die Unterseite der Schnur an. Die Lippe bildet dann zugleich die Verbreiterung an der Unterseite der Schnur. So wird einerseits die richtige Lage der Schnur auf der Oberfläche der Feder gesichert. Andererseits kann die Schnur in der Nut, die oberhalb der Feder angeordnet ist, fest geklemmt werden. Dies ermöglicht ein besonders einfaches Verlegen.The lip preferably adjoins the underside of the cord. The lip then also forms the widening at the bottom of the string. So on the one hand the correct position of the cord is secured on the surface of the spring. On the other hand, the cord in the groove, which is located above the spring, be clamped firmly. This allows a particularly simple installation.

Bevorzugt ist die Nut oberhalb der Feder sowie die Lippe so dimensioniert, dass die Schnur durch Kraftschluss an dem Paneel gehalten wird, wenn die Lippe in die Nut gebracht ist. Dies ist insbesondere dann von Vorteil, wenn die Paneele einen Belag für eine Wand oder eine Decke bilden. Die Schnur fällt dann nämlich nicht unerwünscht während des Verlegens herunter.Preferably, the groove above the spring and the lip is dimensioned so that the cord is held by adhesion to the panel when the lip is brought into the groove. This is particularly advantageous if the panels form a covering for a wall or a ceiling. The cord then does not fall down undesirably during laying.

Die vorgenannte Lippe der Schnur sowie die vorgenannte Nut oberhalb der Feder bewirken ferner, dass die Schnur im verlegten Zustand zuverlässig im Spalt gehalten wird.The aforementioned lip of the cord and the aforementioned groove above the spring also cause the cord is reliably held in the installed state in the gap.

Gemäß der Erfindung weist die Schnur seltlich eine andere Lippe auf. Ein Paneel weist als Kupplungselement eine Nut auf. Oberhalb der Nut befindet sich seitlich eine Ausnehmung. Die andere Lippe gelangt in diese Ausnehmung, wenn die Paneele mit der Umrandung endgüitig verlegt sind. Die Schnur ist so verbessert gegen ein Herausfallen oder Lösen aus dem Spalt gesichert, wenn die Paneele mit der Schnur bzw. der Umrandung verlegt sind.According to the invention, the cord has a different lip. A panel has a groove as a coupling element. Above the groove is laterally a recess. The other lip enters into this recess when the panels are laid with the border finalgüitig. The string is so improved against falling out or Release from the gap secured when the panels are laid with the cord or the border.

Die andere Lippe ist ebenfalls bevorzugt an der Unterseite der Schnur vorgesehen, um so eine Verbreiterung an der Unterseite zu bilden.The other lip is also preferably provided at the bottom of the string so as to form a widening at the bottom.

Gemäß der Erfindung steht die Lippe länger hervor, die in die Nut oberhalb der Feder hinein reicht, Im Vergleich zu der andere Lippe, die in eine Ausnehmung oberhalb der Nut gelangt. Die längere Lippe dient u. a. dem Halt der Schnur auf der Oberseite der Feder während des Verlegens. Die andere Lippe dient dagegen ausschließlich dem Halt der Schnur im vollständig verlegten Zustand des Belages. Die längere Lippe hat also eine Doppelfunktion. Um während des Verlegens genügend Halt zu bieten, steht diese Lippe vergleichsweise lang seitlich der Schnur hervor. Da die andere, relativ kurzer Lippe lediglich einen Halt während des verlegten Zustands bieten soll, ist es an dieser Seite nicht erforderlich, ebenfalls eine lang vorstehende Lippe vorzusehen. Daher kann diese andere Lippe vergleichsweise kurz sein. Hierdurch lassen sich Fertigungskosten einsparen.According to the invention, the lip projects longer, which extends into the groove above the spring, compared to the other lip, which enters a recess above the groove. The longer lip is used u. a. the hold of the cord on top of the spring during laying. The other lip, on the other hand, serves exclusively to hold the cord in the fully installed condition of the rubber. The longer lip has a double function. In order to provide sufficient support during installation, this lip protrudes comparatively long from the side of the string. Since the other, relatively short lip is only intended to provide a hold during the laid state, it is not necessary on this side to provide a long protruding lip. Therefore, this other lip can be comparatively short. This can save manufacturing costs.

Die Oberseite der Schnur wird bevorzugt durch eine glatte, ebene Fläche gebildet. Die Höhe der Schnur ist so dimensioniert, dass die glatte, ebene Fläche bündig mit den Oberflächen der Paneele abschließt. Der Belag, der durch die Paneele und die Schnüre gebildet wird, weist dann eine glatte, ebene Oberfläche auf. Diese Ist daher leicht zu reinigen. Die Schnüre, die die Paneele umranden, verleihen der Oberfläche ein optisch ansprechendes Aussehen.The top of the cord is preferably formed by a smooth, flat surface. The height of the cord is dimensioned so that the smooth, flat surface is flush with the surfaces of the panels. The covering formed by the panels and cords will then have a smooth, even surface. This is therefore easy to clean. The cords surrounding the panels give the surface a visually pleasing appearance.

Bevorzugt sitzt die Schnur im verlegten Zustand passgenau oder besonders bevorzugt leicht gepresst in dem Spalt. Auf diese Weise Ist der kritische Übergang zwischen zwei Paneelen besonders zuverlässig gegen eindringende Feuchtigkeit geschützt. Der Schutz ist insbesondere dann zuverlässig vorhanden, wenn die Schnüre in den Spalten leicht gepresst sitzen.Preferably, the cord sits in the installed state accurately fit or particularly preferably slightly pressed in the gap. In this way, the critical transition between two panels is special reliably protected against penetrating moisture. The protection is particularly reliable when the cords sit in the columns slightly pressed.

Vorteilhaft besteht die Schnur aus einem komprimierbaren Material wie Gummi oder Silicon. Einerseits wird so die Handhabung erleichtert. Andererseits lässt sich so ein gewünschter Presssitz verwirklichen.Advantageously, the cord is made of a compressible material such as rubber or silicone. On the one hand, the handling is easier. On the other hand, a desired interference fit can be realized in this way.

In einer vorteilhaften Ausgestaltung der Erfindung weist die Schnur im Innern einen Faden auf, der nicht dehnbar ist. Auf diese Weise wird vorteilhaft gewährleistet, dass die Schnur während des Verlegens sowie nach dem Verlegen ihre Länge bei behält. Insgesamt ist so gewährleistet, dass die Oberfläche des Belages frei von Spalten bleibt.In an advantageous embodiment of the invention, the cord has a thread on the inside, which is not stretchable. In this way it is advantageously ensured that the cord retains its length during installation and after installation. Overall, it is ensured that the surface of the covering remains free of gaps.

Bevorzugt sind die Kupplungselemente der Paneele so beschaffen, dass die Paneele im gekoppelten Zustand ein Spiel aufweisen, wenn sich keine Schnur zwischen den beiden Paneelen befindet. Dies erleichtert vor allem das Verschieben entlang der gemeinsamen Fuge, was während des Verlegens regelmäßig erforderlich ist, um Paneele in die endgültige Lage zu verschieben. Bestehen die Paneele ganz oder im wesentlichen aus einem Holzwerkstoff, so besteht das Problem, dass die Paneele sich mit ändernden Feuchtigkeiten ausdehnen oder schrumpfen. Beim Stand der Technik treten dann regelmäßig unerwünscht Spalte zwischen den Paneelen an der Oberfläche auf. Dieser Spaltenbildung wird durch Vorsehen eines Spiels entgegengewirkt.Preferably, the coupling elements of the panels are such that the panels in the coupled state have a game when there is no cord between the two panels. This facilitates above all the displacement along the common joint, which is regularly required during the laying to move panels in the final position. If the panels consist entirely or essentially of a wood-based material, then there is the problem that the panels expand or shrink with changing humidities. In the prior art then occur regularly undesirable gaps between the panels on the surface. This splitting is counteracted by providing a game.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung weist das eine Paneel eine Feder als Kupplungselement auf, die sich zum offenen Ende hin verjüngt. Dies erleichtert das Einfädeln der Feder in die Nut des anderen Paneels, wenn zwei Paneele miteinander gekoppelt werden.In a further advantageous embodiment of the invention, the one panel has a spring as a coupling element, which tapers towards the open end. This facilitates threading the spring into the groove of the other panel when two panels are coupled together.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung ist unterhalb der Feder des einen Paneels ein Verriegelungselement als Kupplungselement vorgesehen, welches nach unten hin hervor steht. Die Nut eines anderen Paneels weist als Kupplungselement an einer unteren Nutflanke am offenen Ende ebenfalls ein nach oben hin vorstehendes Verriegelungselement auf. Im gekoppelten Zustand der beiden Paneele greifen die beiden vorgenannten Verriegelungselemente so hintereinander, dass hierdurch eine Kopplung durch Formschluss parallel zur Oberfläche der beiden Paneele bewirkt wird. Im gekoppelten Zustand der beiden Paneele bewirken dann die Nut und Feder eine Kopplung durch Formschluss senkrecht zur gemeinsamen Oberfläche der beiden Paneele.In a further advantageous embodiment of the invention, a locking element is provided as a coupling element below the spring of the one panel, which protrudes downwards. The groove of another panel also has, as a coupling element on a lower groove flank at the open end, an upwardly projecting locking element. In the coupled state of the two panels, the two aforementioned locking elements engage one behind the other in such a way that a coupling is effected by positive locking parallel to the surface of the two panels. In the coupled state of the two panels then cause the tongue and groove coupling by positive locking perpendicular to the common surface of the two panels.

Die Nut des einen Paneels verjüngt sich bevorzugt zum Nutgrund hin. Dies erleichtert das Einfädeln der Feder des einen Paneels in die Nut des anderen Paneels.The groove of the one panel preferably tapers towards the bottom of the groove. This facilitates threading the spring of one panel into the groove of the other panel.

Bevorzugt ragt die untere Flanke der Nut im Vergleich zur oberen Flanke der Nut weiter seitlich hervor. Das Verriegelungselement am offenen Ende der unteren Flanke kann so leichter gefertigt werden. Auch steht so mehr Platz zur Verfügung, um die erforderlichen Kupplungselemente bereitstellen zu können.Preferably, the lower edge of the groove protrudes laterally in comparison to the upper flank of the groove. The locking element at the open end of the lower edge can be made easier. Also, there is more space available to provide the necessary coupling elements.

Besonders bevorzugt besteht die untere Flanke der Nut gegenüber der oberen Flanke der Nut nur so weit hervor, dass das Verriegelungselement am offenen Ende der unteren Nut außerhalb des Bereichs befindet, der von der oberen Flanke der Nut überdeckt wird. Die untere Flanke der Nut steht also nur minimal hervor. So wird einerseits gewährleistet, dass die Fertigung einfach möglich ist und genügend Platz für die Bildung des Verriegelungselementes am offenen Ende der unteren Flanke zur Verfügung steht. Andererseits werden Materialverluste minimiert. Die Fertigung wird so besonders kostengünstig.Particularly preferably, the lower edge of the groove with respect to the upper edge of the groove protrudes only so far that the locking element is located at the open end of the lower groove outside of the area which is covered by the upper edge of the groove. The lower edge of the groove is therefore only slightly visible. This ensures, on the one hand, that production is easily possible and enough space is available for the formation of the locking element at the open end of the lower flank. On the other hand, material losses are minimized. The production becomes particularly cost-effective.

Besonders bevorzugt sind die Kupplungselementes so beschaffen, dass zwei Paneele durch Verschieben innerhalb einer Ebene miteinander verbunden werden können. Das Verlegen von Paneelen ist dann besonders unkompliziert und in einer Weise möglich, die dem Verbraucher vertraut ist. Zu diesem Zweck muss das Material der Paneele eine gewisse Elastizität aufweisen, damit die Kupplungselemente ineinander klicken können. Holzwerkstoffe wie HDF oder MDF sind für diesen Zweck geeignet.Particularly preferably, the coupling element are such that two panels can be connected by moving within a plane with each other. The laying of panels is then particularly uncomplicated and possible in a way that is familiar to the consumer. For this purpose, the material of the panels must have a certain elasticity, so that the coupling elements can click into each other. Wood materials such as HDF or MDF are suitable for this purpose.

Die vorgenannte Klickverbindung, die ein Verlegen durch Verschieben in einer Ebene ermöglicht, wird insbesondere dann vorgesehen, wenn die Paneele einen Belag für eine Wand oder eine Decke bilden. Eine Klickverbindung ermöglicht nämlich zwar ein leichtes Verlegen. Auf der anderen Seite weist eine Klickverbindung jedoch regelmäßig den Nachteil auf, dass Paneele auch leicht wieder auseinander gezogen werden können. Ein Fußbodenbelag ist sehr viel stärker mechanischen Belastungen ausgesetzt im Vergleich zu einem Belag für eine Wand oder einem Belag für eine Decke. Da die Anforderungen an die Stabilität einer Verbindung zwischen den Paneelen also bei einem Belag für eine Decke oder eine Wand vergleichsweise gering sind, kann eine Klickverbindung insbesondere bei einem Belag für eine Wand oder Decke vorteilhaft eingesetzt werden.The aforementioned click connection, which allows laying by moving in a plane, is provided in particular when the panels form a covering for a wall or a ceiling. Although a click connection allows for easy laying. On the other hand, however, a click connection regularly has the disadvantage that panels can also be easily pulled apart again. A floor covering is much more exposed to mechanical stress compared to a covering for a wall or covering for a ceiling. Since the requirements for the stability of a connection between the panels so in a covering for a ceiling or a wall are comparatively low, a click connection can be advantageously used in particular for a covering for a wall or ceiling.

Die Kupplungselemente sind bevorzugt an sämtlichen vier Selten der Paneele vorgesehen. Die Paneele weisen typischerweise eine rechteckige Oberfläche auf. Die Erfindung betrifft insbesondere Laminatpaneele oder Parkettpaneele.The coupling elements are preferably provided on all four of the rare panels. The panels typically have a rectangular surface. The invention particularly relates to laminate panels or parquet panels.

Vorteilhaft weist die Schnur an Ihrer Unterseite eine Rille auf, die entlang der Schnur verläuft. Diese Rille ermöglicht eine gewisse Zirkulation von Luft. Unterschiede in Bezug auf Feuchtigkeit können sich so verbessert innerhalb der Kupplungselemente ausgleichen.Advantageously, the cord has a groove on its underside, which runs along the string. This groove allows a certain circulation of air. Differences in humidity can thus be better compensated within the coupling elements.

Einem Verziehen des Holzwerkstoffs wird so vorteilhaft entgegengewirkt.Warping of the wood material is counteracted so advantageous.

Die Flächen der Paneele, die seitlich an die gemeinsame Oberfläche der Paneele angrenzen, sind bevorzugt senkrecht zur Oberfläche angeordnet. Beschädigungen an den Kanten werden so besonders gut vermieden, die an die Oberfläche der Paneele angrenzen. Die an dieser Flächen angrenzenden Flächen der Schnur verlaufen bevorzugt parallel, um einen guten Anschluss zwischen den Elenden und der Schnur an der sichtbaren Oberfläche zu gewährleisten.The surfaces of the panels, which laterally adjoin the common surface of the panels, are preferably arranged perpendicular to the surface. Damage to the edges is thus avoided particularly well, which adjoin the surface of the panels. The areas of the cord adjacent to these surfaces preferably extend in parallel to ensure a good connection between the miseries and the cord on the visible surface.

Die Figur zeigt ein bevorzugtes Ausführungsbeispiel der Erfindung.The figure shows a preferred embodiment of the invention.

Ein Paneel 1 ist mit einem Paneel 2 durch Formschluss gekoppelt. Es verbleibt zwischen den Paneelen an der Oberseite 16 ein Spalt, in dem sich eine Schnur 3 befindet. Senkrecht zur Oberfläche 16 sind die Paneele durch Formschluss durch eine Nut 4 und eine Feder 5 miteinander gekoppelt. Das Paneel 1 mit der Nut 4 weist eine untere vorstehende Flanke 6 auf, die seitlich länger hervor steht im Vergleich zur oberen Flanke 7. Am offenen Ende der unteren Flanke 6 steht ein Verriegelungselement 8 nach oben hervor. Die untere Flanke 6 steht im Vergleich zur oberen Flanke 7 nur so weit hervor, wie erforderlich ist, um das Verriegelungselement 8 fräsen zu können, ohne mit einem Fräser weit in die Nut 4 hineinreichen zu müssen. Unterhalb der Feder 5 ist ein nach unten hin vorstehendes Verriegelungselement 9 vorgesehen. Wie in der Figur gezeigt wird, greifen im gekoppelten Zustand von zwei Paneelen die Verriegelungselement 8 und 9 hintereinander. Die beiden Paneele 1 und 2 werden so formschlüssig parallel zur Oberfläche 16 sowie senkrecht zur gemeinsamen Fuge miteinander gekoppelt.A panel 1 is coupled to a panel 2 by positive engagement. It remains between the panels on the top 16 a gap in which a cord 3 is located. Perpendicular to the surface 16, the panels are coupled by positive engagement by a groove 4 and a spring 5. The panel 1 with the groove 4 has a lower protruding edge 6, which laterally protrudes longer in comparison to the upper edge 7. At the open end of the lower edge 6, a locking element 8 protrudes upwards. The lower edge 6 is compared to the upper edge 7 only so far out, as required, to mill the locking element 8, without having to extend far into the groove 4 with a cutter. Below the spring 5, a downwardly projecting locking element 9 is provided. As shown in the figure, engage in the coupled state of two panels, the locking element 8 and 9 in a row. The two panels 1 and 2 are so positively coupled parallel to the surface 16 and perpendicular to the common joint with each other.

Die untere vorstehende Flanke 6 des Paneel 1 mit der Nut 4 ist hinreichend elastisch, um das Paneel 2 mit dem Paneel 1 durch Verschieben in einer Ebene verbinden zu können.The lower protruding edge 6 of the panel 1 with the groove 4 is sufficiently elastic to connect the panel 2 with the panel 1 by moving in a plane can.

Die Unterseite 10 der Schnur 3 verläuft parallel zur Oberfläche 16. Die Oberseite 1 1 der Feder 5 verläuft ebenfalls parallel zur Oberfläche 16. Dieser parallele Verlauf der beiden vorgenannten Flächen ermöglicht es, während des Verlegens die Schnur 3 mit ihrer Unterseite 10 auf der Oberseite 11 der Feder 5 abzulegen. Die Schnur 3 weist seitlich eine Lippe 1 2 auf, die relativ lang hervor steht und sich bei der Unterseite befindet. Hierdurch verbreitert sich die Schnur nach unten zu Unterseite 10 hin. Oberhalb der Feder 5 ist eine Nut 13 vorgesehen. In diese Nut 13 reicht die Lippe 1 2 der Schnur 3 hinein. Die Lippe 1 2 ist so dimensioniert, dass die Schnur 3 durch Reibschluss beziehungsweise Kraftschluss auf der Oberseite 11 der Feder 5 gehalten wird, wenn die Lippe 1 2 in die Nut 13 geschoben worden ist. Oberhalb der Nut 4 ist eine Ausnehmung 14 vorgesehen. In diese Ausnehmung 14 reicht im verlegten Zustand eine andere Lippe 15 der Schnur 3 hinein, die der Lippe 1 2 gegenüber liegt. Da die Lippe 15 lediglich dem Halt der Schnur innerhalb des Spalts während des verlegten Zustands dient, steht diese seitlich an der Unterseite der Schnur 3 weniger weit hervor im Vergleich zur Lippe 12. Beide Lippen 12 und 15 verbreitern die Schnur 3 nach unten zur Unterseite 10 hln. Dadurch liegt die Schnur 3 sicher auf der Oberfläche 11 der Feder 5 auf.The underside 10 of the cord 3 is parallel to the surface 16. The top 1 1 of the spring 5 is also parallel to the surface 16. This parallel course of the two aforementioned surfaces makes it possible, while laying the cord 3 with its bottom 10 on the top 11th the spring 5 store. The cord 3 has laterally on a lip 1 2, which protrudes relatively long and is located at the bottom. As a result, the cord widens down to bottom 10 out. Above the spring 5, a groove 13 is provided. In this groove 13, the lip 1 2 of the cord 3 extends into it. The lip 1 2 is dimensioned so that the cord 3 is held by frictional engagement or adhesion on the upper side 11 of the spring 5 when the lip 1 2 has been pushed into the groove 13. Above the groove 4, a recess 14 is provided. In this recess 14 extends in the installed state another lip 15 of the cord 3, which is the lip 1 2 opposite. Since the lip 15 only serves to maintain the cord within the gap during the laid state, it protrudes laterally on the underside of the cord 3 less far in comparison to the lip 12. Both lips 12 and 15 widen the cord 3 down to the bottom 10th hln. As a result, the cord 3 lies securely on the surface 11 of the spring 5.

Die Lippen (12,15) der Schnur verjüngen sich bevorzugt zum offenen Ende nach außen hin. Bevorzugt verjüngt sich die Nut 13 zum Nutgrund hin. Sind zwei Paneele miteinander gekoppelt, so gilt entsprechendes für die Ausnehmung 14, die dann mit der Oberseite der Feder zusammen ebenfalls eine Nut bildet, die sich zum Nutgrund hin verjüngt. Hierdurch wird das Verlegen weiter vereinfacht.The lips (12, 15) of the cord preferably taper towards the open end toward the outside. Preferably, the groove 13 tapers towards the bottom of the groove. If two panels are coupled together, the same applies to the recess 14, which then together with the top of the spring also forms a groove which tapers towards the bottom of the groove. This further simplifies laying.

Werden die beiden Paneele 1 und 2 miteinander verbunden, ohne dass sich eine Schnur 3 im verbleibenden Spalt an der Oberfläche befindet, so verbleibt ein Spiel zwischen den Paneelen und zwar parallel zur Oberfläche 16.Das vorsehen dieses Spiels trägt vor allem dazu bei, dass Dehnungserscheinungen und Schrumpfungserscheinungen kompensiert werden können. Dehnungserscheinungen und Schrumpfungserscheinungen ferner durch Vorsehen der Schnur kompensiert, die aus kompressiblen Material ganz oder überwiegend besteht.If the two panels 1 and 2 connected to each other without a string 3 is in the remaining gap on the surface, so there remains a game between the panels and parallel to the surface 16.The provision of this game contributes mainly to the fact that elongation phenomena and shrinkage phenomena can be compensated. Strain phenomena and shrinkage phenomena are further compensated by providing the cord which consists entirely or predominantly of compressible material.

Im Inneren der Schnur 3 verläuft ein Faden 1 7. Der Faden 1 7 besteht aus einem nicht dehnbaren Material. Der Faden 1 7 wird im übrigen von einem kompressiblen Material wie Gummi umhüllt. An der Unterseite 17 der Schnur 3 befindet sich eine Rille 18. Die Rille 18 verläuft entlang der Schnur 3. Diese ermöglicht einen Feuchtigkeitstransport und damit einen Ausgleich der Feuchtigkeit innerhalb des Holzmaterials, aus dem die Paneele im wesentlichen bestehen.Inside the cord 3 runs a thread 1 7. The thread 1 7 consists of a non-stretchable material. The thread 1 7 is wrapped by the rest of a compressible material such as rubber. At the bottom 17 of the cord 3 is a groove 18. The groove 18 extends along the cord 3. This allows a moisture transport and thus a balance of moisture within the wood material from which the panels consist essentially.

Derzeit wird HDF als Holzmaterial bevorzugt. Hieraus besteht die Basisplatte, die als Träger dient. Ein Dekor oberhalb der Basisplatte wird entweder durch ein Dekorpapier nebst abriebfester Schicht gebildet oder aber durch eine Schicht, die im wesentlichen aus Holz gebildet wird. Unterhalb der Basisplatte ist in der Regel ein Gegenzug zum Beispiel in Form eines Papieres vorgesehen. Unterhalb des Gegenzugs kann eine Trittschall dämmende Schicht angebracht sein.Currently, HDF is preferred as wood material. This consists of the base plate, which serves as a carrier. A decor above the base plate is formed either by a decor paper together with abrasion-resistant layer or by a layer that is formed essentially of wood. Below the base plate is usually provided a return, for example in the form of a paper. Below the counter-train a footfall sound insulating layer may be appropriate.

Derzeit ist ein solches Paneel typischerweise 5 bis 15 Millimeter dick. Die Oberseite der Schnur ist typischerweise ein Millimeter bis 10 Millimeter breit.Currently, such a panel is typically 5 to 15 millimeters thick. The top of the string is typically one millimeter to 10 millimeters wide.

Oberhalb der Ausnehmung 14 des Paneels 1 sowie oberhalb der Lippe 15 der Schnur 3 kann sich eine weitere Ausnehmung bei der Schnur 3 sowie eine vorstehende Lippe des Paneels 1 befinden, die ergänzend dem Halt der Schnur innerhalb des Spalts dienen.Above the recess 14 of the panel 1 and above the lip 15 of the cord 3, a further recess in the String 3 and a protruding lip of the panel 1, which serve in addition to the maintenance of the cord within the gap.

Die beiden Paneele 1 und 2 können auch durch Verschwenken miteinander verbunden werden. Zu diesen Zweck wird das Paneel zwei während des Verlegens schräg gehalten, so dass die Feder 5 schräg in die Nut 4 hineinreicht. Die Schnur 3 befindet sich dabei auf der Oberfläche der Feder 5. Die Lippe 12 befindet sich in der Nut 13 oberhalb der Feder. Das Paneel 2 wird nun nach unten verschwenkt und somit dem Paneel 1 verbunden.The two panels 1 and 2 can also be connected to each other by pivoting. For this purpose, the panel two is held obliquely during installation, so that the spring 5 extends obliquely into the groove 4. The cord 3 is located on the surface of the spring 5. The lip 12 is located in the groove 13 above the spring. The panel 2 is now pivoted downwards and thus connected to the panel 1.

Einfacher ist es jedoch, die Schnur 3 zunächst auf der Oberseite der Feder 5 abzusetzen und die Lippe 1 2 in die Nut 13 hinein zu schieben. Anschließend wird das Paneel zwei innerhalb einer Ebene in Richtung auf das Paneel 1 geschoben, bis die Feder 5 in die Nut 4 gelangt ist und die Verriegelungselement 8 und 9 hintereinander greifen.However, it is simpler to first set down the cord 3 on the upper side of the spring 5 and to push the lip 1 2 into the groove 13. Subsequently, the panel is pushed two within a plane in the direction of the panel 1 until the spring 5 has entered the groove 4 and the locking element 8 and 9 engage in succession.

Die in der Figur gezeigte Ausführungsform dient insbesondere als Belag für eine Wand oder eine Decke.The embodiment shown in the figure serves in particular as a covering for a wall or a ceiling.
