Description

Die Erfindung betrifft ein Fußbodenpaneel mit rechteckigem Format, mit einem Holzwerkstoffkern und einer Dekorschicht an einer Oberseite des Fußbodenpaneels, mit paarweise gegenüberliegenden Seitenkanten, wobei ein Paar Seitenkanten formschlüssig wirkende komplementäre Hakenprofile aufweist, nämlich einen Aufnahmehaken, der einer Unterseite des Fußbodenpaneels zugewandt ist, sowie an der gegenüberliegenden Seitenkante einen Arretierhaken, der der Oberseite des Fußbodenpaneels zugewandt ist, wobei sowohl der Aufnahmehaken als auch der Arretierhaken eine distale Seitenfläche mit wenigstens einem hervorstehenden Rastelement aufweist, welchem eine Aufnahmetasche in dem komplementären Aufnahmehaken zugeordnet ist, und der Arretierhaken durch eine Arretierbewegung senkrecht zur Ebene des Fußbodenpaneels mit dem Aufnahmehaken verriegelbar ist, wobei zwischen dem Rastelement des Arretierhakens und der Oberseite des Fußbodenpaneels, bezogen auf die Gesamtdicke des Fußbodenpaneels, wenigstens ein Abstand von einem Drittel der Gesamtdicke des Fußbodenpaneels vorgesehen ist, und wobei die distale Seitenfläche des Arretierhakens zwei Rastelemente aufweist.The invention relates to a floor panel with rectangular format, with a wood-based material core and a decorative layer on an upper side of the floor panel, with pairwise opposite side edges, with a pair of side edges having positively acting complementary hook profiles, namely a receiving hook, which faces a bottom of the floor panel, as well as to the opposite side edge of a locking hook, which faces the top of the floor panel, wherein both the receiving hook and the locking hook has a distal side surface with at least one protruding locking element, which is associated with a receiving pocket in the complementary receiving hook, and the locking hook by a locking movement perpendicular to Level of the floor panel with the receiving hook is lockable, wherein between the locking element of the locking hook and the top of the floor panel, based on the total thickness of the floor panel, at least a distance of one third of the total thickness of the floor panel is provided, and wherein the distal side surface of the locking hook has two locking elements.

Aus der WO 01/75247 A1 sind gattungsgemäße Fußbodenpaneele bekannt. Gemäß dem Ausführungsbeispiel der Fig. 5 sind bei diesem Stand der Technik an wenigstens zwei gegenüberliegenden Seitenkanten die erwähnten Hakenprofile vorgesehen. Die beiden Rastelemente vergrößern das Maß an Hinterschneidung und erhöhen die Haltekraft, die einem Auseinanderbewegen der Hakenprofile entgegenwirkt. Die beiden übrigen Seitenkanten können komplementäre Profile aufweisen, die auf einer Nut und einer Feder basieren. Diese Profile lassen sich durch schräges Ansetzen eines neuen Fußbodenpaneels mit seiner Seitenkante an eine Seitenkante eines liegenden Fußbodenpaneels und anschließendes Herabschwenken des neuen Fußbodenpaneels in die Ebene des liegenden Fußbodenpaneels miteinander verbinden. Letztere Profile sind formschlüssig ausgebildet. Profile dieser Kategorie dienen dazu, Fußbodenpaneele einer ersten Paneelreihe mit Fußbodenpaneelen einer folgenden Paneelreihe zu verbinden.From the WO 01/75247 A1 are generic floor panels known. According to the embodiment of FIG. 5, the mentioned hook profiles are provided in this prior art on at least two opposite side edges. The two locking elements increase the amount of undercut and increase the holding force, which counteracts a moving apart of the hook profiles. The two remaining side edges may have complementary profiles based on a groove and a spring. These profiles can be connected by obliquely applying a new floor panel with its side edge to a side edge of a horizontal floor panel and then pivoting down the new floor panel in the plane of the horizontal floor panel. The latter profiles are formed positively. Profiles of this category serve to connect floor panels of a first row of panels to floor panels of a following panel row.

Die eingangs erwähnten Hakenprofile dienen hingegen dazu, Fußbodenpaneele miteinander zu verbinden, die in derselben Reihe angeordnet sind.The hook profiles mentioned above, however, serve to connect floor panels together, which are arranged in the same row.

Sowohl die Verriegelung eines neuen Fußbodenpaneels an einer vorderen Reihe als auch die Verhakung mit einem Fußbodenpaneel derselben Paneelreihe werden durch die Schwenkbewegung herbeigeführt.Both the locking of a new floor panel on a front row and the entanglement with a floor panel of the same panel row are brought about by the pivoting movement.

Die Verhakung erfolgt, indem der Arretierhaken in den Aufnahmehaken herabgeschwenkt wird. Der Arretierhaken bewegt sich dabei innerhalb einer Drehebene, die senkrecht zur Oberseite des Fußbodenpaneels ausgerichtet ist. Auf diese Weise geschieht die Verriegelung des Fußbodenpaneels an der Vorderreihe gleichzeitig mit der Verhakung mit einem Fußbodenpaneel derselben Paneelreihe. Die Rastelemente weisen eine Hinterschneidung auf, die einem Auseinanderbewegen zusammengefügter Hakenprofile entgegenwirkt.The hooking is done by the locking hook is pivoted down into the receiving hook. The locking hook moves within a plane of rotation, which is aligned perpendicular to the top of the floor panel. In this way, the locking of the floor panel at the front row is done simultaneously with the entanglement with a floor panel of the same row of panels. The latching elements have an undercut, which counteracts a disassembly of assembled hook profiles.

Aus der WO 01/02670 A1 ist ein allgemeiner Stand der Technik bekannt. Eine Ausführungsform mit formschlüssigen Hakenprofilen ist in Fig. 5.1 der WO 01/02670 A1 gezeigt. Die ausschnittsweise Darstellung zeigt die komplementären Hakenprofile im zusammengefügten Zustand. Beide Hakenprofile weisen an distalen Seitenflächen Rastelemente mit hervorstehender Krümmung auf. Die Rastelemente greifen jeweils in Aufnahmetaschen des Hakenprofils des benachbarten Fußbodenpaneels ein.From the WO 01/02670 A1 is well known in the art. An embodiment with positive hook profiles is shown in FIG. 5. 1 of the WO 01/02670 A1 shown. The fragmentary illustration shows the complementary hook profiles in the assembled state. Both hook profiles have locking elements with protruding curvature on distal side surfaces. The locking elements each engage in receiving pockets of the hook profile of the adjacent floor panel.

Es hat sich gezeigt, dass die Dekorschicht an der Oberseite des Fußbodenpaneels während und nach der Arretierung der Hakenelemente schadhaft wird. Die Dekorschicht löst sich ab und die Oberseite des Fußbodenpaneels schüsselt, dass heißt, an den Seitenkanten stellt sich an der Oberseite die Dekorschicht auf.It has been found that the decorative layer on the top of the floor panel during and after the locking of the hook elements is defective. The decorative layer separates and the top of the floor panel bowls, that is, at the side edges is on top of the decorative layer on.

Weitere Fußbodenpaneele mit Aufnahmehaken, Arretierhaken und daran vorgesehenen Rastelementen sind bekannt aus der DE 201 20 704 U1 , DE 200 02 744 U1 , EP 1 512 808 A1 , DE 202 03 311 U1 und EP 1 350 904 A1 .Other floor panels with receiving hooks, locking hooks and locking elements provided thereon are known from the DE 201 20 704 U1 . DE 200 02 744 U1 . EP 1 512 808 A1 . DE 202 03 311 U1 and EP 1 350 904 A1 ,

Der Erfindung liegt die Aufgabe zugrunde, ein vereinfacht gestaltetes Fußbodenpaneel zu schaffen, das gut handhabbar und gut verhakbar ist.The invention has for its object to provide a simplistic designed floor panel that is easy to handle and good hooked.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass ein erstes näher an der Oberseite des Fußbodenpaneels angeordnetes Rastelement des Arretierhakens weiter von der distalen Seitenfläche des Arretierhakens hervorsteht, als das zweite Rastelement.According to the invention the object is achieved in that a first arranged closer to the top of the floor panel locking element of the locking hook further protrudes from the distal side surface of the locking hook, as the second locking element.

Dies bewirkt, dass das kürzer vorstehende Rastelement die Rastposition für das weiter vorstehende Rastelement passieren kann, ohne eine Verrastung herbeizuführen. Anschließend verrasten beide Rastelemente nahezu gleichzeitig in dem Aufnahmehaken.This causes the shorter protruding locking element can pass the locking position for the further projecting locking element, without causing a catch. Then lock both locking elements almost simultaneously in the receiving hook.

Die Erfindung macht sich die besondere Eigenschaft des Holzwerkstoffkerns zunutze. Diese besondere Eigenschaft besteht in einer abnehmenden Dichte des Holzwerkstoffmaterials mit zunehmender Materialtiefe. Eine Holzwerkstoffplatte besteht aus Holzpartikeln, die mit Bindemitteln versehen und in einer Presse verdichtet worden sind. Die Dichte einer solchen Holzwerkstoffplatte ist nahe einer Oberfläche, wie der Oberseite beziehungsweise der Unterseite der Holzwerkstoffplatte hoch. Die Dichte nimmt mit zunehmendem Abstand zur Oberfläche ab. Sowohl von der Oberseite als auch von der Unterseite des Fußbodenpaneels nimmt die Dichte mit zunehmender Materialtiefe zunächst ab. Die Dichte erreicht in einer mittleren Ebene der Holzwerkstoffplatte ein Minimum.The invention makes use of the special property of the wood-based material core. This special feature consists in a decreasing density of the wood material with increasing material depth. A wood-based panel consists of wood particles that have been provided with binders and compacted in a press. The density of such a wood-based panel is high near a surface such as the top and bottom of the wood-based panel. The density decreases with increasing distance to the surface. Either From the top as well as from the bottom of the floor panel, the density initially decreases with increasing material depth. The density reaches a minimum in a middle level of the wood-based panel.

Bei dem bekannten Fußbodenpaneel wurde festgestellt, dass ein Rastelement an einer distalen Seitenfläche eines Hakenelements dann Beschädigungen an der Dekorschicht hervorruft, wenn es nahe der Oberseite des Fußbodenpaneels angeordnet ist. Nahe der Oberseite weist der Holzwerkstoffkern eine hohe Dichte auf. Wenn in diesem Bereich Druck durch ein Rastelement ausgeübt wird, treten Stauchungen im Material auf, die das Material spalten. Innere Risse wachsen. Schichten des Holzwerkstoffs schälen ab.In the known floor panel has been found that a locking element on a distal side surface of a hook element then causes damage to the decorative layer when it is located near the top of the floor panel. Near the top, the wood-based material core has a high density. When pressure is applied in this area by a detent element, compressions occur in the material which split the material. Inner cracks grow. Layers of wood-based material peel off.

Die Erfindung sieht vor, das Rastelement des Arretierhakens in größerer Materialtiefe anzuordnen, das heißt mit einem größeren Abstand von der Oberseite des Fußbodenpaneels.The invention provides to arrange the locking element of the locking hook in greater material depth, that is, with a greater distance from the top of the floor panel.

Das Rastelement hat einen vergrößerten Abstand zu der Oberseite des Fußbodenpaneels und liegt nunmehr in einem weichen Bereich des Holzwerkstoffs, der eine verhältnismäßig geringe Dichte im Vergleich zur Dichte nahe der Oberfläche aufweist. Eine Spaltung des Materials nahe der Dekorschicht tritt nicht auf, weil das weichere Material nachgiebiger ist. Zudem bewirkt der vergrößerte Abstand des Rastelements zur Oberseite des Fußbodenpaneels, dass Druck und Stauchungen nicht bis an die Dekorschicht heranreichen können.The locking element has an increased distance to the top of the floor panel and is now in a soft area of the wood material, which has a relatively low density compared to the density near the surface. Cleavage of the material near the decorative layer does not occur because the softer material is more compliant. In addition, the increased distance of the locking element to the top of the floor panel, that pressure and compression can not reach up to the decorative layer.

Das Rastelement reicht vorzugsweise über die gesamte Länge der Seitenkante. Alternativ können mehrere in Reihe hintereinander liegende Rastelemente vorgesehen sein.The latching element preferably extends over the entire length of the side edge. Alternatively, a plurality of locking elements lying one behind the other in series can be provided.

Eine weitere Verbesserung ergibt sich dann, wenn die Seitenkanten der Hakenprofile ebene Berührflächen aufweisen, die der Oberseite des Fußbodenpaneels zugewandt sind und sich im gefügten Zustand zweier Fußbodenpaneele solche Berührflächen aneinanderschmiegen. Die Berührflächen haben im zusammengefügten Zustand zweier Fußbodenpaneele Kontakt. Von der Oberseite der Fußbodenpaneele betrachtet ergibt sich eine geschlossene Fuge. Eine geschlossene Fuge ist erwünscht. Sie kann durch die Form der Hakenprofile begünstigt werden. Dies beispielsweise, indem das Hakenprofil mit einer schiefen Ebene ausgestattet und durch die Verrastung eine elastische Verformung erhält, welche die Berührflächen zweier Fußbodenpaneele gegeneinander zwingt.A further improvement results when the side edges of the hook profiles have flat contact surfaces which face the upper side of the floor panel and, in the assembled state of two floor panels, nestle such contact surfaces. The contact surfaces are in the assembled state of two floor panels contact. Viewed from the top of the floor panels results in a closed joint. A closed joint is desired. It can be favored by the shape of the hook profiles. This, for example, by the hook profile equipped with an inclined plane and receives an elastic deformation by the latching, which forces the contact surfaces of two floor panels against each other.

Nützlich ist, wenn zumindest das zweite Rastelement während einer Arretierbewegung berührungslos an der Berührfläche des Aufnahmehakens vorbeibewegbar ist. Bevorzugt ragt das erste Rastelement nicht weiter von der distalen Seitenfläche hervor, als dessen Berührfläche. Es kann geduldet werden, wenn das erste Rastelement in leichtem Schleifkontakt an der Berührfläche vorbeibewegt wird, wobei der schleifende Kontakt keine Beeinträchtigung der Funktion des Rastelements hervorruft.It is useful if at least the second latching element during a locking movement without contact on the contact surface of the receiving hook is moved past. Preferably, the first latching element does not protrude farther from the distal side surface than the contact surface thereof. It can be tolerated if the first detent element is moved past the contact surface in slight sliding contact, wherein the abrading contact causes no impairment of the function of the detent element.

Günstigerweise weist der Aufnahmehaken wenigstens einen Rasthöcker auf, und der Rasthöcker ist in Arretierrichtung der Aufnahmetasche vorgelagert. Der Rasthöcker ragt weiter von der Seitenkante hervor als die Berührfläche des Aufnahmehakens. Durch elastische Verformung, sowohl des Rastelements als auch des Rasthöckers, kommen diese in hinterschnittenen Eingriff miteinander. Weil der Rasthöcker von der Seitenkante des Aufnahmehakens weiter hervorsteht als dessen Berührfläche, kann das Rastelement des Arretierhakens ungehindert an der Berührfläche des Aufnahmehakens vorbeibewegt werden, bis es gegen den Rasthöcker stößt und diesen durch beiderseitige elastische Verformung überwindet.Conveniently, the receiving hook has at least one latching bump, and the latching bump is preceded in the locking direction of the receiving pocket. The detent raises further from the side edge than the contact surface of the receiving hook. By elastic deformation, both of the locking element and the latching ram, these come in undercut engagement with each other. Because the pawl protrudes from the side edge of the receiving hook further than the contact surface, the locking element of the locking hook can be freely moved past the contact surface of the receiving hook until it abuts against the ratchet and this overcomes by mutual elastic deformation.

Bevorzugt sind zwei Rasthöcker und zwei Aufnahmetaschen vorgesehen. Diese wirken mit zwei Rastelementen des Arretierhakens zusammen und erhöhen die Haltekraft der Hakenprofile im verhakten Zustand.Preferably, two latching bumps and two receiving pockets are provided. These interact with two locking elements of the locking hook and increase the holding force of the hook profiles in the hooked state.

Damit die Verhakung beider Rastelemente des Arretierhakens mit den beiden Rasthöckern des Aufnahmehakens erleichtert wird, weist der erste Rasthöcker einen geringeren Abstand zur Oberseite des Fußbodenpaneels auf und steht um ein geringeres Maß von der distalen Seitenfläche des Aufnahmehakens hervor als der zweite Rasthöcker.Thus, the entanglement of the two latching elements of the locking hook is facilitated with the two latching hooks of the receiving hook, the first latching cusp is closer to the top of the floor panel and projects to a lesser extent from the distal side surface of the receiving hook than the second latching bump.

Nach der Zeichnung weist das Fußbodenpaneel 1 einen rechteckigen, tafelförmigen Holzwerkstoffkern 2 auf. Es ist an einer Oberseite 3 mit einer Dekorschicht 4 versehen und weist zwei parallele lange Seitenkanten 5 und 6 sowie zwei parallele kurze Seitenkanten 7 und 8 auf. Die Seitenkanten sind zur Verbindung mehrerer gleichartiger Fußbodenpaneele 1 vorgesehen. Die langen Seitenkanten 5 und 6 weisen zu diesem Zweck formschlüssig wirkende Verriegelungsprofile auf, nämlich eine hinterschnittene Feder 5a an der Seitenkante 5 und eine hinterschnittene Nut 6a an der gegenüberliegenden Seitenkante 6.After the drawing, the floor panel 1 a rectangular, tabular wood-based material core 2. It is provided on a top 3 with a decorative layer 4 and has two parallel long side edges 5 and 6 and two parallel short side edges 7 and 8. The side edges are provided for connecting a plurality of similar floor panels 1. The long side edges 5 and 6 have for this purpose positively acting locking profiles, namely an undercut spring 5a on the side edge 5 and an undercut groove 6a on the opposite side edge 6.

Mehrere Fußbodenpaneele 1 werden reihenweise verlegt. Die Verriegelungsprofile der langen Seitenkanten 5 und 6 dienen der Verbindung der einzelnen Reihen der Fußbodenpaneele 1. Ein neues Fußbodenpaneel 1 wird zuerst mit einer langen Seitenkante 5 an ein komplementäres Verriegelungsprofil einer vorherige Paneelreihe angesetzt. Das Ansetzen des neuen Fußbodenpaneels 1 erfolgt winklig. Damit ist gemeint, das neue Fußbodenpaneel 1 zu Beginn des Fügevorgangs in einer Ebene gehalten wird, die schräg zu der Ebene angeordnet ist, welche die Fußbodenpaneele 1 in ihrer Gebrauchslage einnehmen. Die Gebrauchslage der Fußbodenpaneele 1 soll im Sinne der Erfindung auch als Gebrauchsebene der Fußbodenpaneele 1 bezeichnet werden.Several floor panels 1 are laid in rows. The locking profiles of the long side edges 5 and 6 serve to connect the individual rows of the floor panels 1. A new floor panel 1 is first attached with a long side edge 5 to a complementary locking profile of a previous row of panels. The attachment of the new floor panel 1 is angled. This means that the new floor panel 1 is held at the beginning of the joining process in a plane which is arranged obliquely to the plane which occupy the floor panels 1 in their position of use. The position of use of the floor panels 1 should be referred to in the context of the invention as a plane of use of the floor panels 1.

Durch Herabschwenken des neuen Fußbodenpaneels 1 in die Gebrauchsebene verbinden sich die Verrieglungsprofile der langen Seitenkanten 5 und 6 formschlüssig. Der Formschluss verhindert ein Auseinanderbewegen der beiden Fußbodenpaneele 1 in der Gebrauchsebene quer zu den langen Seitenkanten 5 und 6. Außerdem verhindert der Formschluss senkrecht zur Gebrauchsebene einen Höhenversatz zwischen den verriegelten langen Seitenkanten 5 und 6.By pivoting down the new floor panel 1 in the plane of use connect the Verrieglungsprofile the long side edges 5 and 6 positively. The positive locking prevents the two floor panels 1 from moving apart in the plane of use transversely to the long side edges 5 and 6. In addition, the positive connection perpendicular to the plane of use prevents a height offset between the locked long side edges 5 and 6.

Innerhalb einer Reihe werden Fußbodenpaneele 1 an ihren kurzen Seitenkanten 7 und 8 miteinander verbunden, die auch Stirnkanten 7 und 8 genannt werden.Within a row floor panels 1 are connected to each other at their short side edges 7 and 8, which are also called end edges 7 and 8.

An den Stirnkanten 7 und 8 des gezeigten Fußbodenpaneels 1 sind Hakenprofile vorgesehen. In Bezug auf eine horizontale Gebrauchslage des Fußbodenpaneels 1 werden komplementäre Hakenprofile durch eine vertikale Fügebewegung miteinander verbunden.Hook profiles are provided on the end edges 7 and 8 of the floor panel 1 shown. With respect to a horizontal position of use of the floor panel 1 complementary hook profiles are connected by a vertical joining movement.

Im Bildvordergrund von Fig. 1 ist ein Hakenprofil einer Stirnkante 7 des Fußbodenpaneels 1 zu sehen. Das Hakenprofil ragt von der Stirnkante 7 hervor und ist nahe der Unterseite des Fußbodenpaneels 1 angeordnet. Es ist zur Oberseite 3 des Fußbodenpaneels 1 hin offen und wird im Sinne der Erfindung als Aufnahmehaken 9 bezeichnet. Die gegenüberliegende Stirnkante 8 weist ein komplementäres Hakenprofil auf, dessen Querschnittsform vergrößert in Fig. 2 dargestellt ist. Dieses Hakenprofil wird im Sinne der Erfindung als Arretierhaken 10 bezeichnet. Fig. 3 zeigt vergrößert eine Querschnittsform des Aufnahmehakens 9 aus Fig. 1.In the foreground of Fig. 1 is a hook profile of a front edge 7 of the floor panel 1 can be seen. The hook profile protrudes from the front edge 7 and is located near the bottom of the floor panel 1. It is open to the top 3 of the floor panel 1 and is referred to as a receiving hook 9 in the context of the invention. The opposite end edge 8 has a complementary hook profile whose cross-sectional shape increases in Fig. 2 is shown. This hook profile is referred to in the context of the invention as a locking hook 10. Fig. 3 shows enlarged a cross-sectional shape of the receiving hook 9 from Fig. 1 ,

Sowohl in Fig. 2 als auch in Fig. 3 ist die Dichte des Holzwerkstoffs des Holzwerkstoffkerns 2 durch eine Punktierung des Querschnitts symbolisch dargestellt. Der Holzwerkstoffkern 2 weist nahe der Oberseite 3 und nahe der Unterseite eine hohe Dichte auf. Von der Oberseite 3 nimmt die Dichte mit zunehmender Materialtiefe ab und erreicht etwa in einer mittleren Ebene oder einer mittleren Schicht des Holzwerkstoffkerns 2 ein Minimum.As well in Fig. 2 as well as in Fig. 3 the density of the wood material of the wood material core 2 is shown symbolically by a puncture of the cross section. The wood-based core 2 has near the top 3 and near the bottom to a high density. From the upper side 3, the density decreases with increasing material depth and reaches a minimum approximately in a middle plane or a middle layer of the wood material core 2.

Der Arretierhaken 10 weist gemäß Fig. 2 eine distale Seitenfläche 11 auf, die mit einer zur Oberseite gewandten Berührfläche 12 und mit zwei hervorstehenden Rastelementen 13 und 14 versehen ist. Der Abstand von der Oberseite 3 bis zu dem ersten Rastelement 13 beträgt mehr als ein Drittel der Gesamtdicke des Fußbodenpaneels 1. Das zweite Rastelement 14 ist hinter dem ersten Rastelement 13 in größerem Abstand von der Oberseite 3 des Fußbodenpaneels 1 angeordnet. Beide Rastelemente 13 und 14 befinden sich in Materialbereichen des Holzwerkstoffs, die eine verhältnismäßig geringe Dichte aufweisen verglichen mit der Dichte nah an der Oberseite 3 des Fußbodenpaneels 1.The locking hook 10 has according to Fig. 2 a distal side surface 11 which is provided with an upper surface facing the contact surface 12 and with two protruding locking elements 13 and 14. The distance from the upper side 3 to the first locking element 13 is more than one third of the total thickness of the floor panel 1. The second locking element 14 is disposed behind the first locking element 13 at a greater distance from the top 3 of the floor panel 1. Both locking elements 13 and 14 are in material areas of the wood material, which have a relatively low density compared to the density close to the top 3 of the floor panel. 1

Außer der distalen Seitenfläche 11 weist der Arretierhaken 10 eine Hinterschneidungsfläche 15 auf, die im verbundenen Zustand mit dem Aufnahmehaken 9 zusammenwirkt. Zur Unterseite gewandt ist an dem Arretierhaken 10 eine Vertiefung 16 vorgesehen.In addition to the distal side surface 11, the locking hook 10 has an undercut surface 15, which cooperates with the receiving hook 9 in the connected state. Turned to the bottom is on the locking hook 10, a recess 16 is provided.

Der in Fig. 3 dargestellte Aufnahmehaken 9 weist an einer distalen Seitenfläche 17 ein einzelnes Rastelement 18 auf. Die distale Seitenfläche 17 des Aufnahmehakens 9 hat eine geringere Höhe als die distale Seitenfläche 11 des Arretierhakens 10. Der Aufnahmehaken 9 ist mit einer Hinterschneidungsfläche 19 versehen, die im verhakten Zustand zweier Fußbodenpaneele 1 mit der Hinterschneidungsfläche 15 des Arretierhakens 10 zusammenwirkt. Die Hinterschneidungsfläche 19 des Aufnahmehakens 9 ist in einem Abstand hinter der distalen Seitenfläche 17 angeordnet.The in Fig. 3 shown receiving hooks 9 has on a distal side surface 17 on a single locking element 18. The distal side surface 17 of the receiving hook 9 has a lower height than the distal side surface 11 of the locking hook 10. The receiving hook 9 is provided with an undercut surface 19 which cooperates in the hooked state of two floor panels 1 with the undercut surface 15 of the locking hook 10. The undercut surface 19 of the receiving hook 9 is arranged at a distance behind the distal side surface 17.

Die Hinterschneidungsflächen 15 und 19 verhakter Fußbodenpaneele 1 verhindern ein Auseinanderbewegen der Fußbodenpaneele 1 in ihrer Gebrauchsebene und senkrecht zu den Stirnkanten 7 und 8.The undercut surfaces 15 and 19 entangled floor panels 1 prevent moving apart of the floor panels 1 in their plane of use and perpendicular to the end edges 7 and 8.

Etwa in demselben Abstand hinter der Hinterschneidungsfläche 19 des Aufnahmehakens 9 ist eine Aufnahmefläche 20 mit Aufnahmetaschen 21 und 22 für die beiden Rastelemente 13 und 14 des Arretierhakens 10 vorgesehen. Zur Oberseite 3 des Fußbodenpaneels 1 hin geht die Aufnahmefläche 20 in eine Berührfläche 23 über. Die Berührflächen 12 und 23 von Arretierhaken und Aufnahmehaken bilden im zusammengefügten Zustand der Fußbodenpaneele 1 eine von der Oberseite 3 sichtbare Fuge 24.About the same distance behind the undercut surface 19 of the receiving hook 9, a receiving surface 20 is provided with receiving pockets 21 and 22 for the two locking elements 13 and 14 of the locking hook 10. Towards the top 3 of the floor panel 1, the receiving surface 20 merges into a contact surface 23. The contact surfaces 12 and 23 of locking hook and receiving hooks form in the assembled state of the floor panels 1 a visible from the top 3 joint 24th

Die Aufnahmefläche 20 weist zwei hervorstehende Rasthöcker 25 und 26 auf. Jeder Aufnahmetasche 21 und 22 ist einer der Rasthöcker 25 beziehungsweise 26 vorgeschaltet. In der Richtung, in welcher der Arretierhaken 10 zwecks Verrastung bewegt wird, befindet sich vor jeder Aufnahmetasche 21 beziehungsweise 22 ein Rasthöcker 25 beziehungsweise 26. Die Rastelemente 13 und 14 des Arretierhakens 10 müssen unter elastischer Verformung des Holzwerkstoffs hinter die Rasthöcker 25 und 26 bewegt werden, mit denen sie auf diese Weise eine Hinterschneidung bilden. Die so hinterschnittenen Hakenprofile sichern die Fußbodenpaneele gegen Auseinanderbewegen in einer Richtung senkrecht zur Gebrauchsebene der Fußbodenpaneele 1.The receiving surface 20 has two projecting detent bumps 25 and 26. Each receiving pocket 21 and 22 is connected to one of the detent bumps 25 and 26, respectively. In the direction in which the locking hook 10 is moved for locking, located in front of each receiving pocket 21 and 22, a detent 25 or 26. The locking elements 13 and 14 of the locking hook 10 must be moved under elastic deformation of the wood material behind the detent bumps 25 and 26 with which they form an undercut in this way. The thus undercut hook profiles secure the floor panels against movement apart in a direction perpendicular to the plane of use of the floor panels. 1

Der erste Rasthöcker 25 ragt weiter von der Seitenkante 7 hervor als die Berührfläche 23 des Aufnahmehakens 9. Weil der erste Rasthöcker 25 von der Seitenkante 7 des Aufnahmehakens 9 weiter hervorsteht als dessen Berührfläche 23, ist das Rastelement 13 des Arretierhakens 10 so ausgelegt, dass es ungehindert an der Berührfläche 23 des Aufnahmehakens 9 vorbeibewegt werden kann, bis es gegen den Rasthöcker 25 stößt und diesen durch beiderseitige elastische Verformung überwindet. Das zweite Rastelement 14 des Arretierhakens 10 ragt kürzer von der distalen Seitenfläche 11 hervor. Es kann dadurch an dem ersten Rasthöcker 25 des Aufnahmehakens 9 vorbeibewegt werden. Sobald das zweite Rastelement 14 des Arretierhakens 10 den zweiten Rasthöcker 26 erreicht, kommt ein Kontakt zustande, weil der zweite Rasthöcker 26 weiter hervorragt als der erste Rasthöcker 25.Because the first detent bump 25 protrudes further from the side edge 7 of the receiving hook 9 than the contact surface 23 thereof, the detent element 13 of the detent hook 10 is designed such that it protrudes from the side edge 7 unhindered can be moved past the contact surface 23 of the receiving hook 9 until it abuts against the latching bump 25 and this overcomes by mutual elastic deformation. The second latching element 14 of the locking hook 10 protrudes shorter from the distal side surface 11. It can thereby be moved past the first detent bump 25 of the receiving hook 9. As soon as the second latching element 14 of the locking hook 10 reaches the second latching bump 26, contact is established because the second latching bump 26 protrudes further than the first latching bump 25.

Um das zweite Rastelement 14 in die Aufnahmetasche 22 hinter dem zweiten Rasthöcker 26 zu bewegen, muss der Holzwerkstoff elastisch verformt werden.In order to move the second latching element 14 into the receiving pocket 22 behind the second latching bump 26, the wood-based material must be elastically deformed.

Die Verrastung der beiden Rastelemente 13 und 14 vorbei an den Rasthöckern 25 und 26 erfolgt bei der vorliegenden Konstruktion nahezu simultan.The locking of the two locking elements 13 and 14 past the latching ridges 25 and 26 takes place almost simultaneously in the present construction.

Die elastische Verformung und Materialstauchung erfolgt in einem großen Abstand von der Oberseite 3 der Fußbodenpaneele 1. In diesem Bereich ist die Dichte des Holzwerkstoffkerns 2 gering. Auf diese Weise werden Spaltbildungen nahe der Dekorschicht 4 der Fußbodenpaneele 1 vermieden.The elastic deformation and material compression takes place at a large distance from the top 3 of the floor panels 1. In this area, the density of the wood material core 2 is low. In this way, formation of gaps near the decorative layer 4 of the floor panels 1 are avoided.
