A vertical slot (28) is formed in the lip, and increases elastic resilience of the lip. The slot is extended into a base layer of the former panel.

Description

Die Erfindung betrifft eine Verbindung für zwei Paneele gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a connection for two panels according to the preamble of patent claim 1.

Derartige Verbindungen für Paneele, Fußbodenelemente sind beispielsweise aus der EP 1 650 375 B1 oder der EP 1 415 056 B1 bekannt.Such compounds for panels, floor elements are for example from the EP 1 650 375 B1 or the EP 1 415 056 B1 known.

Dabei sind entlang der Längskanten der rechteckförmigen Paneele nut-/federartige Verbindungen ausgeführt, die durch Einschwenken eines zu verlegenden Paneels in ein bereits verlegtes Paneel verbunden werden, wobei die Schwenkachse in etwa entlang der Längsseite des bereits verlegten Paneels liegt. Diese längsseitige Verbindung ist mit Verriegelungsmitteln versehen, die eine Verriegelung in Horizontalund Vertikalrichtung bereitstellen. An den kürzeren Stirnseiten der Paneele sind bei den bekannten Lösungen jeweils Druckknopf- oder Hakenverbindungen ausgeführt, die beim Herabschwenken entlang der Längsseiten in Eingriff miteinander gelangen. Zur Vertikalverriegelung kann dabei in einem Stirnflächenabschnitt des einen Paneels ein in die Trennebene hineinragendes Federelement gelagert sein, das beim Herabschwenken des anderen Paneels federnd aus der Trennebene herausbewegt wird und dann im vollständig verschwenkten Zustand wieder zurückschnappt und eine Verriegelungsfläche hintergreift, sodass die beiden Paneele in Vertikalrichtung relativ zueinander lagepositioniert sind.Nut- / spring-like connections are along the longitudinal edges of the rectangular panels executed, which are connected by pivoting a panel to be laid in an already laid panel, the pivot axis is approximately along the longitudinal side of the already laid panel. This longitudinal connection is provided with locking means which provide locking in the horizontal and vertical directions. At the shorter end faces of the panels each push-button or hook connections are executed in the known solutions, which get along when pivoting along the longitudinal sides into engagement with each other. For vertical locking can thereby be stored in an end face portion of a panel projecting into the parting plane spring element which is moved outwardly when pivoting down the other panel from the parting plane and then snaps back in the fully pivoted state and engages behind a locking surface, so that the two panels in the vertical direction Positioned relative to each other.

Nachteil bei dieser Lösung ist, dass das Lösen, beispielsweise während des Verlegens des Bodens nur durch Verschieben der beiden Paneele entlang der Querseiten möglich ist.Disadvantage of this solution is that the release, for example, during the laying of the floor only by moving the two panels along the transverse sides is possible.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, eine Verbindung für Paneele zu schaffen, bei denen das Lösen der querseitigen Verbindung vereinfacht ist.In contrast, the invention has for its object to provide a connection for panels in which the release of the lateral connection is simplified.

Diese Aufgabe wird durch eine Verbindung für zwei Paneele mit den Merkmalen des Patentanspruchs gelöst.This object is achieved by a connection for two panels having the features of the claim.

Erfindungsgemäß ist die Verbindung zweier Paneele als Druckknopf- oder Hakenverbindung ausgeführt, wobei beide Paneele zueinander korrespondierende Hakenelemente aufweisen, bei denen entlang einer Seite des einen Paneels eine über eine Trennebene hinaus verlängerte Unterlippe ausgebildet ist, von der ein Verriegelungsvorsprung nach oben, zum anderen Paneel auskragt, der im verriegelten Zustand in eine Verriegelungsausnehmung am anderen Paneel eintaucht. An einem Paneel ist ein elastisch federndes Element angeordnet, das in Wirkeingriff mit einer Verriegelungsfläche am anderen Paneel bringbar ist. Dieses Element kann als gesondertes Federelement oder aber auch einstückig mit dem Paneel ausgeführt sein. Erfindungsgemäß ist an der verlängerten Unterlippe ein Schlitz ausgeführt, durch den eine Verbiegbarkeit der Unterlippe im Sinne einer vereinfachten Entriegelung der Paneele bewirkt wird.According to the invention the connection of two panels is designed as a push button or hook connection, wherein both panels have mutually corresponding hook elements, in which along one side of the one panel beyond a parting plane extended lower lip is formed, protrudes from a locking projection upwards to the other panel which immersed in the locked state in a locking recess on the other panel. On a panel, an elastically resilient element is arranged, which can be brought into operative engagement with a locking surface on the other panel. This element can be designed as a separate spring element or else in one piece with the panel. According to the invention, a slot is made on the extended lower lip, by which a bendability of the lower lip in terms of a simplified unlocking of the panels is effected.

Durch diesen Schlitz können die Paneele entlang der besagten Kante durch Horizontalverschieben zueinander gelöst werden, ohne dass das elastische Element zurückgedrückt werden muss oder ohne dass es einer Verschiebung entlang der betreffenden Kante bedarf. Dieses Verschieben kann bei ungünstigen Verlegebedingungen, beispielsweise im Bereich einer Wand oder dergleichen sehr schwierig oder nahezu unmöglich sein.Through this slot, the panels along the said edge can be solved by horizontal displacement to each other, without the elastic element must be pushed back or without the need for a shift along the relevant edge. This shifting can be very difficult or almost impossible under unfavorable laying conditions, for example in the range of a wall or the like.

Bei einem Ausführungsbeispiel der Erfindung ist der Schlitz als Vertikalschlitz - bezogen auf die Verlegefläche - ausgeführt. Ein derartiger Vertikalschlitz lässt sich mit sehr geringem Aufwand beim Fräsen des Nutprofils fertigen.In one embodiment of the invention, the slot as a vertical slot - based on the laying surface - executed. Such a vertical slot can be finished with very little effort when milling the groove profile.

Vorteilhafter Weise wird der erfindungsgemäße Schlitz bei einem Mehrschichtparkett ausgeführt, wobei sich dann der Schlitz in einer Tragschicht zum Boden hin bis zu einer Unterzugschicht erstrecken kann.Advantageously, the slot according to the invention is carried out in a multi-layer parquet, wherein then the slot can extend in a supporting layer to the bottom up to a lower layer.

Der Schlitz ist vorzugsweise in dem Bereich angeordnet, in dem im verriegelten Zustand die Auflage des einen Paneels auf der Unterlippe des bereits verlegten Paneels endet, sodass der Schlitz gerade überdeckt ist.The slot is preferably arranged in the region in which, in the locked state, the support of the one panel ends on the lower lip of the already installed panel, so that the slot is just covered.

Die Erfindung wird anhand eines Parkettbodens erläutert, der aus einer Vielzahl von Parkettpaneelen 1, 2 zusammengesetzt ist, wobei entlang der Längsseiten der Paneele die eingangs beschriebenen nut-/federartigen Verbindungselemente mit Horizontal- und Vertikalverriegelung ausgeführt sind und entlang der Stirnseiten eine Druckknopfverbindung ausgeführt ist, deren Aufbau im Folgenden erläutert wird. Das Parkett ist als Mehrschichtparkett mit einer Deckschicht 4, einer mittleren Tragschicht 6 und einer Unterzugschicht 8 ausgeführt und wird über eine Hakenverbindung 10 verbunden, die durch Einschwenken des Paneels 2 entlang der nicht dargestellten Längsseite des bereits verlegten Paneels 1 in Wirkverbindung gebracht wird. Zur Horizontalverriegelung ist bei der gezeigten Verbindung ein Federelement 12 vorgesehen, das während des Absenkens des Paneels 2 hin zum verlegten Paneel 1 elastisch aus einer Trennebene 14 heraus bewegt wird und dann wieder zurückschnappt, um die Vertikalverriegelung durchzuführen.The invention will be explained with reference to a parquet floor, which is composed of a plurality of parquet panels 1, 2, along the longitudinal sides of the panels the groove / spring-like connecting elements described above are designed with horizontal and vertical locking and along the front sides a push-button connection is executed, the structure of which will be explained below. The parquet is designed as a multi-layer parquet with a cover layer 4, a middle support layer 6 and a Unterzugschicht 8 and is connected via a hook connection 10 which is brought by pivoting of the panel 2 along the longitudinal side of the already laid panel 1, not shown in operative connection. For horizontal locking a spring element 12 is provided in the connection shown, which is elastically moved during the lowering of the panel 2 towards the laid panel 1 out of a parting plane 14 and then snaps back to perform the vertical locking.

Einzelheiten der Verbindung werden anhand der Figuren 2 und 3 erläutert.Details of the connection will be based on the FIGS. 2 and 3 explained.

Das Paneel 1 hat eine sich über die Trennebene 14 hinaus erstreckende bodenseitige Unterlippe 16, die in dem in Figur 2 unteren Bereich der Tragschicht 6 und den benachbarten Teil der Unterzugschicht 8 gebildet ist. An dem frei auskragenden Endabschnitt der Unterlippe 16 ist ein Verriegelungsvorsprung 18 ausgeführt, der mit einer schräg zur Horizontalen angestellten Horizontalverriegelungsfläche 20 ausgeführt ist. Eine Stirnkante 22 des Verriegelungsvorsprungs ist mehrfach angefast. Der Anstellwinkel der Horizontalverriegelungsfläche 20 ist beim dargestellten Ausführungsbeispiel kleiner als 45° mit Bezug zur Horizontalen.The panel 1 has a bottom-side lower lip 16 extending beyond the parting plane 14 and extending into the in-plane lower lip 16 FIG. 2 bottom portion of the support layer 6 and the adjacent part of the lower layer 8 is formed. At the freely projecting end portion of the lower lip 16, a locking projection 18 is carried out with an obliquely to horizontal horizontal locking surface 20 is executed. An end edge 22 of the locking projection is chamfered several times. The angle of attack of the horizontal locking surface 20 is less than 45 ° with respect to the horizontal in the illustrated embodiment.

Im Übergangsbereich der Unterlippe 16 zu einer in der Trennebene 14 liegenden Stirnfläche 24 verbreitert sich die Unterlippe 16 über eine Anschrägung 26 oder Verrundung. In diesem Übergangsbereich ist ein Schlitz 28 ausgebildet, der sich in Vertikalrichtung von einer Auflagefläche 30 der Unterlippe 16 bis hin zur Unterzugschicht 8 erstreckt. Die Bodenfläche dieses nutartigen Schlitzes 28 ist beim dargestellten Ausführungsbeispiel verrundet.In the transition region of the lower lip 16 to a lying in the parting plane 14 end face 24, the lower lip 16 widened via a chamfer 26 or rounding. In this transition region, a slot 28 is formed, which extends in the vertical direction from a support surface 30 of the lower lip 16 to the lower layer 8 layer. The bottom surface of this groove-like slot 28 is rounded in the illustrated embodiment.

In der Stirnfläche 24 ist eine zur Horizontalen schräg angestellte Führungsnut 32 für das oben genannte Federelement 12 ausgebildet. Dieses ist beim dargestellten Ausführungsbeispiel als etwa U-förmig gekrümmte Feder ausgeführt, die mit ihren kurzen U-Schenkeln 34 (nur einer sichtbar in Figur 1) am Boden der Führungsnut 32 anliegt. Eine Basis 37 (senkrecht zur Zeichenebene verlaufend) des Federelements 12 steht über die Trennebene 14 hinaus aus der Stirnfläche 24 heraus.In the end face 24 an inclined obliquely to the horizontal guide groove 32 is formed for the above spring element 12. This is performed in the illustrated embodiment as an approximately U-shaped curved spring, with their short U-legs 34 (only one visible in FIG. 1 ) abuts the bottom of the guide groove 32. A base 37 (perpendicular to the plane of the drawing) of the spring element 12 protrudes beyond the parting plane 14 out of the end face 24.

Das andere Paneel ist korrespondierend ausgeführt und hat dementsprechend an seiner Unterseite gemäß Figur 3 eine Verriegelungsausnehmung 36 mit einer Verriegelungsfläche 38 ausgeführt, die entsprechend der Horizontalverriegelungsfläche 20 ausgebildet ist, sodass im verlegten Zustand (Figur 1) die beiden Flächen 38, 20 flächig aneinander liegen und somit eine Auseinanderbewegung der beiden Paneele 1, 2 in Horizontalrichtung verhindern.The other panel is executed correspondingly and accordingly has on its underside according to FIG. 3 a locking recess 36 with a locking surface 38 executed, which is formed according to the horizontal locking surface 20 so that in the installed state ( FIG. 1 ), the two surfaces 38, 20 lie flat against each other and thus prevent a movement apart of the two panels 1, 2 in the horizontal direction.

Diese Verriegelungsfläche 38 ist an der Rückseite eines gegenüber der Verlegefläche nach oben (Ansicht nach Figur 3) versetzten Vorsprungs 40 ausgebildet, der eine Horizontalfläche 42 hat, die im verriegelten Zustand auf der Auflagefläche 30 aufliegt. Stirnseitig ist der Vorsprung 40 mit einer Fase 44 ausgeführt, an die sich eine Vertikalverriegelungsnut 46 anschließt. Diese ist nach unten hin durch eine zur Horizontalen schräg angestellte Vertikalverriegelungsfläche 48 begrenzt, an der im verriegelten Zustand (Figur 1) der auskragende, angeschrägte Bereich der Basis 37 anliegt, um die Paneele 1, 2 entlang der Querseiten in Vertikalrichtung zu verriegeln. Dabei steht die Fase 44 und der Übergangsbereich zur Vertikalverriegelungsnut 46 im Abstand zur Anschrägung 26 des anderen Paneels 1. Die Stirnflächenbereiche oberhalb der Verriegelungsausnehmung 48 liegen im verriegelten Zustand bündig aneinander an, sodass kein Spalt entsteht. Wie in Figur 1 sichtbar, ist die Stirnfläche 52 des Paneels 2 im Bereich der Tragschicht 6 gegenüber dem Stirnflächenbereich der Deckschicht 4 leicht zurückgesetzt, sodass im verriegelten Zustand ein kleiner Spalt s im Bereich der Tragschicht 6 entsteht.This locking surface 38 is at the back of a relative to the laying surface upwards (view FIG. 3 ) offset projection 40 is formed, which has a horizontal surface 42 which rests on the support surface 30 in the locked state. The front side of the projection 40 is designed with a chamfer 44, which is followed by a Vertikalverriegelungsnut 46. This is limited at the bottom by an obliquely inclined to the horizontal vertical locking surface 48, at the locked state ( FIG. 1 ), the projecting, tapered portion of the base 37 is applied to lock the panels 1, 2 along the transverse sides in the vertical direction. In this case, the chamfer 44 and the transition region to the Vertikalverriegelungsnut 46 is at a distance from the chamfer 26 of the other panel 1. The end surface areas above the locking recess 48 are in the locked state flush with each other, so that no gap is formed. As in FIG. 1 Visible, the end face 52 of the panel 2 is slightly set back in the region of the support layer 6 with respect to the end face region of the cover layer 4, so that in the locked state, a small gap s is formed in the region of the support layer 6.

Bei herkömmlichen Verbindungen sind ähnliche Horizontal- und Vertikalverriegelungselemente vorgesehen. Diese lassen sich nur durch Relativverschieben der beiden Paneele 1, 2 senkrecht zur Zeichenebene lösen. Bei der erfindungsgemäßen Lösung können die beiden Paneele 1, 2 in derVerlegeebene in Horizontalrichtung (senkrecht zur Stirnseite) auseinander gezogen werden, wobei dann die Unterlippe 16 aufgrund der Schwächung durch den Schlitz 28 in Pfeilrichtung gemäß Figur 1 nach unten ausgelenkt wird und die beiden Flächenabschnitte 20, 38 aneinander abgleiten. Beim weiteren Auseinanderschieben gleitet die obere Fläche 50 des Verriegelungsvorsprungs 18 an der Horizontalfläche 42 ab, bis der Verriegelungseingriff gelöst ist.In conventional connections similar horizontal and vertical locking elements are provided. These can be solved only by relative displacement of the two panels 1, 2 perpendicular to the plane. In the solution according to the invention, the two panels 1, 2 in the laying plane in the horizontal direction (perpendicular to the front side) are pulled apart, in which case the lower lip 16 due to the weakening through the slot 28 in the arrow direction FIG. 1 is deflected down and slide the two surface portions 20, 38 to each other. Upon further sliding apart, the upper surface 50 of the locking projection 18 slides on the horizontal surface 42 until the locking engagement is released.

Selbstverständlich kann die Erfindung mit dem Schlitz 28 auch bei einem Zweischichtparkett oder einem Laminatboden verwendet werden.Of course, the invention can be used with the slot 28 in a two-layer parquet or a laminate floor.

Offenbart ist eine Verbindung für zwei Paneele, die durch Absenken eines Paneels auf ein anderes, bereits verlegtes Paneel verbindbar sind, wobei beide Paneele in dem zu verbindenden Bereich mit korrespondierenden hakenförmigen Elementen ausgeführt sind und in Vertikalrichtung mittels eines Federelementes verriegelt sind. Die Verbindung ist so ausgestaltet, dass sie sich durch Auseinanderbewegen der Paneele in Horizontalrichtung lösen lässt.Disclosed is a connection for two panels, which are connectable by lowering a panel to another, already laid panel, both panels are executed in the region to be connected with corresponding hook-shaped elements and are locked in the vertical direction by means of a spring element. The connection is designed so that it can be solved by moving the panels apart in the horizontal direction.
