Description

Die Erfindung betrifft ein Fußbodenpaneel mit einer Einrichtung zur Verbindung mit wenigstens einem weiteren Fußbodenpaneel gleicher Art auf einem Untergrund, wobei

  • bei der in die Nut ein länglicher, wenigstens teilweise flexibler, separater Verbinder eingelassen ist, der im verlegten Zustand mit der Seitenfläche eines gegenüberliegenden Fußbodenpaneels zusammenwirkt,
  • wobei der Verbinder im unverformten Zustand etwa einen dachrinnenförmigen Querschnitt hat und eine gewölbte Wandung besitzt,
  • die Wandung mit einer teilzylindrischen Innenfläche an einer Kante dieser Innenfläche - in einem Querschnitt des Verbinders gesehen - in ein Kopfstück und andererseits in einen Fuß übergeht, der eine freie Seitenfläche und eine Standfläche aufweist,
  • das Kopfstück im in die Nut eingepassten Zustand des Verbinders wenigstens teilweise gegen eine erste Nutflanke der Nut drückt,
  • die Seitenfläche des Fußbodenpaneels eine beim Zusammenfügen von Fußbodenpaneelen in den von der Innenfläche des Verbinders aufgespannten Innenraum eingreifende Verriegelungswalze aufweist, die eine Zusammenwirkung mit dem Verbinder hervorruft.
The invention relates to a floor panel with a device for connection to at least one further floor panel of the same kind on a substrate, wherein
  • the floor panels each have a first and a second profiled side surface opposite to each of which an abutment surface is arranged which is perpendicular to a tread surface or a base surface of the floor panel,
  • the impact surface merges into a groove running parallel to the tread surface along the side surface, which groove is delimited towards the tread surface by a groove flank,
  • protrudes over the abutment surface a locking arm, which has a bottom and terminates in a directed to the tread surface, approximately trapezoidal lip, which in turn has an inner surface facing the groove
  • in which in the groove an elongate, at least partially flexible, separate connector is inserted, which cooperates in the installed state with the side surface of an opposite floor panel,
  • wherein the connector in the undeformed state has approximately a gutter-shaped cross-section and has a curved wall,
  • the wall having a part-cylindrical inner surface at an edge of this inner surface - seen in a cross-section of the connector - merges into a head piece and on the other hand into a foot having a free side surface and a footprint,
  • the head piece in the fitted state of the connector at least partially presses against a first groove flank of the groove in the groove,
  • the side surface of the floor panel has an interlocking roller engaging with the interior space of the connector when joining floor panels into the interior space of the connector, which causes cooperation with the connector.

In DE 102 37 397 A1 sind unterschiedliche Ausführungsformen eines elastischen, ein- oder zweiteiligen Verbinders mit Hohlkammern dargestellt, der einem Fensterdichtungsprofil ähnelt. Außerdem ist der Fig. 5 ein ankerartiger, aus zwei Teilen bestehender Verbinder zu entnehmen, bei dem ein über eine Seitenfläche des einen Paneels ragender Mittelsteg, Stempel genannt, in einen Inneraum eines in eine Nut eines zweiten Paneels hineingepressten C-Profils mit Kopfstück eingreift. Die profilierten Seitenflächen der beiden miteinander verbundenen Paneele verlaufen im Wesentlichen schräg zur Tritt- bzw. Bodenfläche der Paneele, wobei die gekoppelten Teile des Verbinders senkrecht auf die Seitenflächen gerichtet sind. Dabei sind beide Teile des Verbinders spiegelsymmetrisch zu seiner Längsachse aufgebaut. Nachteilig bei einer so ausgestalteten Paneelverbindung mit zweiteiligem Verbinder gemäß Fig. 5 ist, dass eine nachträgliche Trennung der miteinander verbundenen Fußbodenpaneele nicht realisierbar ist. Auch eine Verbindung der Fußbodenpaneele miteinander bzw. ihre Verlegung auf einen Untergrund scheint problematisch zu sein, weil eine Montage in Horizontalrichtung mit Hilfe des bekannten Schlagklotzes unmöglich und Montage mit Schwenkbewegung sehr erschwert ist.In DE 102 37 397 A1 different embodiments of an elastic, one- or two-part connector are shown with hollow chambers, which resembles a window sealing profile. In addition, the Fig. 5 an anchor-like, two-part connector can be seen in which a projecting over a side surface of a panel center web, called punch, engages in an interior space of a pressed into a groove of a second panel C-shaped profile with head. The profiled side surfaces of the two interconnected panels are substantially oblique to the tread or bottom surface of the panels, with the coupled portions of the connector directed perpendicularly to the side surfaces. Both parts of the connector are constructed mirror-symmetrically to its longitudinal axis. A disadvantage of a thus configured panel connection with two-piece connector according to Fig. 5 is that a subsequent separation of the interconnected floor panels is not feasible. Also, a connection of the floor panels together or their laying on a surface seems to be problematic, because a mounting in the horizontal direction impossible with the help of the known impact block and assembly with pivoting movement is very difficult.

Ferner ist aus WO 2008/004960 eine Einrichtung zur Verbindung von Fußbodenpaneelen miteinander bekannt, bei der in eine runde Nut eines bereits verlegten Fußbodenpaneels (gemäß Figuren 6a bis 6d der WO 2008/004960 ) ein bumerangartiger Verbinder eingesetzt ist, der durch ein Gegenpaneel unter Hebelwirkung bewegt wird, bis ein dickerer Rand des Verbinders - im Querschnitt der Paneelverbindung gesehen-in eine zu dem Rand kompatible Nut des Gegenpaneels einspringt. Der separate Verbinder hat die Aufgabe, die Verriegelung der Fußbodenpaneele im Wesentlichen senkrecht gegenüber der Trittfläche zu gewährleisten.Furthermore, it is off WO 2008/004960 a device for the connection of floor panels known to each other, in which in a round groove of an already laid floor panel (according to Figures 6a to 6d of WO 2008/004960 ) is inserted a boomerangartiger connector which is moved by a counter panel under leverage until a thicker edge of the connector - seen in cross-section of the panel connection - einspringt in a marginal compatible groove of the Gegenpaneels. The separate connector has the task to ensure the locking of the floor panels substantially perpendicular to the tread.

Die Aufgabe der horizontalen Verriegelung übernimmt auf herkömmliche Weise der Verriegelungsarm mit seiner Lippe. Zwar verfügt der aus WO 2008/004960 bekannte Verbinder über eine zusätzliche, auf das Gegenpaneel gerichtete eigene Lippe. Diese sorgt allerdings lediglich für eine Verstärkung der vorhandenen horizontalen Verriegelung. Nachteilig bei der aus WO 2008/004960 bekannten Einrichtung ist, dass der Verbinder vor dem Zusammenfügen beider Fußbodenpaneele relativ leicht aus der Befestigung in der Nut herausfallen kann, insbesondere dann, wenn das Material des Verbinders federelastisch ist.The task of horizontal locking takes over in a conventional manner, the locking arm with his lip. Although has the off WO 2008/004960 known connector via an additional, directed to the Gegenpaneel own lip. However, this only provides for an increase in the existing horizontal locking. A disadvantage of the WO 2008/004960 known device is that the connector prior to joining the two floor panels can relatively easily fall out of the attachment in the groove, especially if the material of the connector is resilient.

Aufgabe der Erfindung ist, eine alternative, gattungsgemäße, jedoch in ihrer Funktion und Handhabung einfachere Einrichtung zur Verbindung von polygonalen, plattenförmigen, untereinander gleichen Fußbodenpaneelen miteinander mit Hilfe der separaten Verbinder zu entwickeln.The object of the invention is to develop an alternative, generic, but simpler in their function and handling device for connecting polygonal, plate-shaped, mutually identical floor panels together using the separate connector.

Diese Aufgabe ist durch eine Einrichtung der eingangs genannten Art gelöst, bei der

  • die Nut eine gegenüber der Stoßfläche zurückversetzte, ebene Nutrückwand aufweist,
  • wobei das Kopfstück an einem flexiblen Schenkel des Verbinders angeordnet ist, so dass beim Zusammenfügen von Fußbodenpaneelen das Kopfstück in Richtung Nutrückwand verschwenkt werden kann,
  • die Innenfläche der Lippe gegenüber dem Boden hinterschnitten ist, so dass der Fuß mit seiner Seitenfläche sowie mit seiner Standfläche im einmontierten Zustand des Verbinders die besagte Innenfläche und den Boden des Verriegelungsarms vor und nach dem Zusammenfügen der beiden Fußbodenpaneele kontaktiert.
This object is achieved by a device of the type mentioned, in which
  • the groove has a flat groove rear wall offset from the impact surface,
  • wherein the head piece is arranged on a flexible leg of the connector, so that when assembling floor panels, the head piece can be pivoted in the direction of the groove rear wall,
  • the inner surface of the lip is undercut with respect to the ground, so that the foot contacted with its side surface and with its base in the assembled state of the connector said inner surface and the bottom of the locking arm before and after the joining of the two floor panels.

Im Weiteren wird ein Fußbodenpaneel, das gegen das bereits verlegte herabgeschwenkt wird, als Gegenpaneel bezeichnet. Die Begriffe, wie "oben", "obere", "unten", "untere", "unterhalb", "oberhalb" etc. beziehen sich auf die auf einen Untergrund verlegten Fußbodenpaneele, wie dies auch in der Zeichnung dargestellt ist. Ferner wird der separate Verbinder als Profil bezeichnet. Die Basisfläche des Paneels ist dabei die, die den Auflage-Untergrund kontaktiert.In addition, a floor panel, which is pivoted down against the already laid, referred to as Gegenpaneel. The terms such as "top", "top", "bottom", "bottom", "below", "above", etc. refer to the laid on a substrate floor panels, as shown in the drawing. Furthermore, the separate connector is referred to as a profile. The base surface of the panel is the one that contacts the support surface.

Bei dem Fußbodenpaneel gemäß Erfindung ist eine sogenannte Hakenverbindung vorhanden, bei der normalerweise die die Hakenverbindung bildenden Teile, Lippe am Verriegelungsarm und die auf den Boden gerichtete Verriegelungswalze des Gegenpaneels, ff miteinander dicht verhakt sein sollen und die Stoßflächen der beiden Fußbodenpaneele in flächigen Kontakt miteinander gebracht werden sollen, um die Verriegelung der Fußbodenpaneele in horizontaler Richtung zu sichern. Für die bekannte Lösung gemäß WO 2008/004960 kann diese Voraussetzung auch dann erfüllt werden, wenn der Verbinder aus der Nut herausgenommen wird. Der separate Verbinder gemäß WO 2008/004960 liegt außerhalb der Flächen, die die eigentliche Hakenverbindung bilden.In the floor panel according to the invention, a so-called hook connection is present, in which normally the hook connection forming parts, lip on the locking arm and directed to the bottom locking roller of the Gegenpaneels, ff should be tightly hooked together and the abutting surfaces of the two floor panels brought into surface contact with each other should be in order to secure the locking of the floor panels in the horizontal direction. For the known solution according to WO 2008/004960 This condition can be met even if the connector is removed from the groove. The separate connector according to WO 2008/004960 lies outside the surfaces that form the actual hook connection.

Es ist nicht zu übersehen, dass die Hakenverbindung bei der erfindungsgemäßen Lösung erst nach dem Zusammenfügen der beiden Fußbodenpaneele zustande kommt, wenn sich zwischen der Innenfläche der Lippe und der beim Zusammenfügen der Fußbodenpaneele in den Verbinder eingreifenden Verriegelungswalze der stegförmige Fuß befindet. Sollte der Verbinder herausgenommen werden, kann wegen entstandener Spalte nicht von einer Hakenverbindung die Rede sein. In dieser Lage wären die beiden Fußbodenpaneele gegeneinander vor dem Verschieben zueinander sowohl in horizontaler als auch in vertikaler Richtung nicht gesichert. Von großem Vorteil ist, dass das Profil gemäß vorliegender Erfindung eine Verriegelung zugleich in beiden Richtungen gewährleisten kann.It is not to be overlooked that the hook connection in the solution according to the invention comes about only after the joining of the two floor panels, when the web-shaped foot is located between the inner surface of the lip and the locking roller engaged in the connector when the floor panels are joined. Should the connector be removed, there can be no question of a hook connection because of the resulting gap. In this position, the two floor panels would not be secured against each other before moving each other both in the horizontal and in the vertical direction. Of great advantage is that the profile according to the present invention can ensure a lock at the same time in both directions.

Vorzugsweise ist der separate Verbinder gemäß Erfindung aus Kunststoff angefertigt. Als Kunststoffe für den Verbinder kommen Thermoplaste, wie Polyethylen (PE), Polypropylen (PP), Polystyrol (PS), Polyamide (PA), Polycarbonate (PC), Polyethylenterephthalat (PET) u. a., sowie sogenannte technische Kunststoffe, wie Styrol-Copolymerisate (ABS), Polyamide (PA), Polycarbonate (PC), Polyethylenterephthalat (PET), Polymethylmethacrylat (PMMA), Polyoxymethylen (POM), Fluorkunststoffe (Teflon), Polyurethane (PUR) in Frage. Auch an sich bekannte Elastomere sind einsetzbar.Preferably, the separate connector according to the invention is made of plastic. Plastics for the connector include thermoplastics, such as polyethylene (PE), polypropylene (PP), polystyrene (PS), polyamides (PA), polycarbonates (PC), Polyethylene terephthalate (PET) and others, as well as so-called engineering plastics, such as styrene copolymers (ABS), polyamides (PA), polycarbonates (PC), polyethylene terephthalate (PET), polymethyl methacrylate (PMMA), polyoxymethylene (POM), fluoroplastics (Teflon), polyurethanes (PUR) in question. Also known per se elastomers can be used.

Das Profil kann auch aus sogenannten Integral-Kunststoffen hergestellt sein. Ein solches Profil kann beispielsweise einen harten Fuß und einen relativ weichen, sich an das Kopfstück anschließenden Schenkel aufweisen. Dabei können das Kopfstück und der Fuß steifer als das rechtliche Material des Profils ausgeführt sein.The profile can also be made of so-called integral plastics. Such a profile may for example have a hard foot and a relatively soft, adjoining the head leg. In this case, the head piece and the foot can be made stiffer than the legal material of the profile.

Ferner kann das Profil aus Metall, Holzwerkstoff oder Verbundstoff gefertigt sein.Furthermore, the profile can be made of metal, wood material or composite.

Der separate Verbinder gemäß Erfindung ist als annähernd dachrinnenförmig bezeichnet, da er ähnlich wie eine übliche Dachrinne eine runde, teilzylindrische Innenfläche, ein wulstartiges Kopfstück und einen dem Kopfstück gegenüber liegenden, entlang des Profils verlaufenden Steg bzw. Fuß aufweist.The separate connector according to the invention is referred to as approximately gutter-shaped, since it has a round, part-cylindrical inner surface, a beaded head and a head piece opposite, extending along the profile web or foot similar to a conventional gutter.

Dabei kann der Fuß stegförmig und/oder massiv sein, wobei von entscheidender Bedeutung ist, dass dieser eine geneigte Seitenfläche aufweist, deren Neigungswinkel zu seiner Standfläche dem besagten scharfen Winkel an der Lippe entspricht. So kann der Fuß und der untere Teil des einmontierten Profils nahezu formschlüssig, und zwar vor und nach der Absenkung des Gegenpaneels, an dem Verriegelungsarm anliegen.In this case, the foot may be web-shaped and / or solid, wherein it is of crucial importance that this has a sloping side surface, the angle of inclination to its footprint corresponds to said sharp angle at the lip. Thus, the foot and the lower part of the einmontierten profile almost form-fitting, before and after the lowering of the Gegenpaneels, abut the locking arm.

Das Profil kann wenigstens in seinem Schenkelbereich elastisch verformbar sein. Die Elastizität des Profils kann durch entsprechende Verengungen oder sanfte Übergange des Schenkels zum Fuß unterstützt sein.The profile may be elastically deformable at least in its leg region. The elasticity of the profile may be assisted by corresponding constrictions or gentle transitions of the leg to the foot.

Das Kopfstück kann eine streifenförmige, ebene, im eingesetzten Zustand der ersten Nutflanke zugewandte, erste Gleitfläche aufweisen, die sich wiederum in eine zweite, nach unten zeigende, schräge Gleitfläche fortsetzt.The head piece may have a strip-shaped, planar, in the inserted state of the first groove flank facing, first sliding surface, which in turn continues in a second, downwardly facing, inclined sliding surface.

Vorzugsweise verläuft die erste, obere Nutflanke der Nut zur Aufnahme des separaten Verbinders parallel und eine zweite, untere Nutflanke schräg zur Tritt- bzw. Basisfläche des Fußbodenpaneels, wobei die untere Nutflanke in den Boden des Verriegelungsarms übergeht. Die beiden Nutflanken schließen sich an eine senkrecht zur Trittfläche angeordnete Nutrückwand besagten Nut an. Die so konfigurierte Nut bietet genügend Platz zum Verschwenken des Kopfstücks. Die ebene Gleitfläche des Kopfstücks verbleibt im nicht durch das herabsenkende Gegenpaneel hervorgerufenen, gespannten Zustand in flächigem Kontakt mit der oberen Nutflanke oder drückt gegen sie.Preferably, the first, upper groove flank of the groove for receiving the separate connector runs parallel and a second, lower groove flank extends obliquely to the base surface of the floor panel, wherein the lower groove flank merges into the bottom of the locking arm. The two groove sides adjoin a groove wall arranged perpendicular to the tread surface said groove. The groove configured in this way provides sufficient space for pivoting the head piece. The flat sliding surface of the head piece remains in the not by the lowering counter-panel caused, tensioned state in surface contact with the upper groove flank or presses against them.

Die gesamte Gleitfläche des Kopfstücks kann - im Querschnitt des Profils gesehen - wenigstens teilweise abgerundet sein.The entire sliding surface of the head piece can - as seen in cross-section of the profile - be at least partially rounded.

Der Boden des Verriegelungsarms verläuft vorzugsweise parallel zur Basisfläche und bildet dann eine Stützfläche für den Fuß und für den unteren Teil der Wandung des Verbinders. Zur Aufnahme eines massiven Fußes, dessen ebene Standfläche sich breiter als die des stegförmigen Fußes erstreckt, eignet sich insbesondere ein ebener oder abgestufter Boden.The bottom of the locking arm is preferably parallel to the base surface and then forms a support surface for the foot and for the lower part of the wall of the connector. To accommodate a massive foot whose flat footprint extends wider than that of the web-shaped foot, in particular a flat or stepped floor is suitable.

Am Boden des Verriegelungsarms kann wenigstens ein parallel zur Nut verlaufender, muldenförmiger Sitz eingearbeitet sein, der vorzugsweise etwa in der Mitte des Bodens, auf jeden Fall außerhalb der unteren geneigten Nutflanke liegt. An dem Sitz kann sich der untere Teil des eingelegten Profils anschmiegen oder abstützen. Für alle Ausführungsformen des einmontierten Profils gemäß Erfindung gilt also das Prinzip dreier Kontaktflächen des Profils mit dem unteren Fußbodenpaneel, nämlich mit der geneigten Innenfläche der Lippe, mit dem Boden des Verriegelungsarms und mit der oberen Nutflanke. Das so festgelegte Profil sitzt sicher an der Seitenfläche des unteren Fußbodenpaneels und hat kaum eine Chance, sich selbstständig zu lösen.At the bottom of the locking arm, at least one trough-shaped seat extending parallel to the groove can be incorporated, which is preferably located approximately in the middle of the floor, in any case outside the lower inclined groove flank. At the seat, the lower part of the inserted profile can nestle or support. For all embodiments of the einmontierten profile according to the invention thus applies the principle of three contact surfaces of the profile with the lower floor panel, namely with the inclined inner surface of the lip, with the bottom of the locking arm and with the upper groove flank. The defined profile sits securely on the side surface of the lower floor panel and has little chance to solve on its own.

Das Kopfstück kann beim Herabschwenken des Fußbodenpaneels in Richtung Boden des bereits verlegten Fußbodenpaneels eine Drehbewegung um den Sitz bzw. um eine Abstufung des Bodens ausüben. Dabei kann der Fuß des Verbinders in seiner Lage an der Innenfläche der Lippe unbeweglich verbleiben.When the floor panel is lowered in the direction of the floor of the already laid floor panel, the head piece can exert a rotary movement about the seat or a gradation of the floor. In this case, the foot of the connector can remain immovable in its position on the inner surface of the lip.

Die Profile können manuell oder mechanisch bzw. mit Hilfe eines Automaten werkseitig in die vorhandene Nut des Fußbodenpaneels eingedrückt sein. Die mit den Profilen versehenen Fußbodenpaneele können in dieser Form gelagert und vertrieben werden.The profiles can be pressed into the existing groove of the floor panel manually or mechanically or with the aid of a machine at the factory. The provided with the profiles floor panels can be stored and distributed in this form.

Wenn das Profil aus Kunststoff hergestellt wird, kann es preiswert als Massenartikel zur Verfügung gestellt werden.If the profile is made of plastic, it can be cheaply made available as a mass-produced article.

Die Profile gemäß Erfindung sind im Wesentlichen für die Schmalkanten der Fußbodenpaneele bestimmt. Allerdings können auch in den längeren Seitenflächen der Fußbodenpaneele integriert sein, wenn diese an den separaten Verbinder entsprechend angepasst werden.The profiles according to the invention are essentially intended for the narrow edges of the floor panels. However, you can also be integrated in the longer side surfaces of the floor panels, if they are adapted to the separate connector accordingly.

Vorteilhaft ist, wenn an der am Gegenpaneel befindlichen Verriegelungswalze eine schräg gegenüber der Trittfläche angeordnete Andrückfläche eingebracht ist, mit der auf die ebene, aber vor allem auf die abgeschrägte Gleitfläche des Kopfstücks ein Druck ausgeübt wird. Die schräge Andrückfläche der nach unten gerichteten Verriegelungswalze liegt unter einem Winkel = 45°, vorzugsweise 60° -± 10° gegenüber der Trittfläche. Dieser Winkel gewährleistet ein optimales Gleiten der Verriegelungswalze am Kopfstück, ohne dass das Kopfstück aus der Nut herausfallen kann.It is advantageous if a pressure surface arranged obliquely opposite the tread surface is introduced on the locking roller located on the counter panel, with which pressure is exerted on the flat, but especially on the bevelled sliding surface of the head piece. The oblique pressure surface of the downward locking roller is at an angle = 45 °, preferably 60 ° - ± 10 ° relative to the tread. This angle ensures optimum sliding of the locking roller on the head piece, without the head piece can fall out of the groove.

Die Verriegelungswalze kann in eine gegenüber der oberen Stoßfläche des Gegenpaneels zurückversetzte Schräge übergehen, derart, dass ein scharfer, etwa V-förmiger Übergang zur Aufnahme des Kopfstücks gebildet ist.The locking roller may transition into a recessed position opposite the upper abutment surface of the mating panel, such that a sharp, approximately V-shaped, transition to receive the header is formed.

Die Fußbodenpaneele als solche können aus Kunststoff, Metall, Holzwerkstoff, darin Papier oder anderen nachwachsenden Rohstoffen, wie Kork, hergestellt sein. Die Fußbodenpaneele können in Massiv- oder Schichtbauweise, wie an sich bekannte HDF- oder MDF-Paneele, gefertigt sein und ein Holz- oder Fliesendekor aufweisen, das mit mindestens einer Schicht aus einem transparenten oder transluzenten Kunstharz abgedeckt ist. Die Fußbodenpaneele können mit antibakteriellen und/oder feuerhemmenden Mitteln ausgerüstet sein.As such, the floor panels can be made of plastic, metal, wood-based material, paper or other renewable raw materials, such as cork. The floor panels can be made in solid or layered construction, such as known HDF or MDF panels, and have a wood or tile decor, which is covered with at least one layer of a transparent or translucent synthetic resin. The floor panels may be equipped with antibacterial and / or fire retardants.

Die Figuren 1, 2 und 17 zeigen Details zweier gleicher Fußbodenpaneele 1.1, 1.2 vor und nach dem Herabschwenken des Fußbodenpaneels 1.2 (Gegenpaneel) in Richtung Untergrund 11, auf den das Fußbodenpaneel 1.1 bereits verlegt ist. Charakteristisch für die Figuren ist das Fehlen eines separaten Verbinders, der noch im Weiteren detailliert beschrieben werden wird.The FIGS. 1, 2 and 17 show details of two identical floor panels 1.1, 1.2 before and after the pivoting down of the floor panel 1.2 (counter panel) in the direction of the substrate 11, to which the floor panel 1.1 is already laid. Characteristic of the figures is the lack of a separate connector, which will be described in detail below.

Die beiden Fußbodenpaneele 1.1, 1.2 bestehen jeweils aus einer Nutzschicht 39, einer Bodenschicht 40 und einer dazwischen liegenden Kernschicht 38 aus Holzwerkstoff. Die Nutzschicht 39 ist mit einer Dekorschicht 41 versehen, deren Oberfläche eine Trittfläche 6 bildet. Die Bodenschicht 40 weist wiederum eine Basisfläche 26 auf, die den Untergrund 11 kontaktiert (vergleiche Figur 6).The two floor panels 1.1, 1.2 each consist of a wear layer 39, a bottom layer 40 and an intermediate core layer 38 of wood material. The wear layer 39 is provided with a decorative layer 41, the Surface forms a tread surface 6. The bottom layer 40 in turn has a base surface 26 which contacts the substrate 11 (see FIG FIG. 6 ).

Das Fußbodenpaneel 1.1 zeichnet sich durch eine profilierte, durch die Tritt- und Basisflächen 6, 26 begrenzte Seitenfläche 8.1 aus, aufweisend eine Stoßfläche 7.1, eine gegenüber der Stoßfläche zurückversetzte Nut 9 und einen über die Stoßfläche 7.1 hinausragenden Verriegelungsarm 14 mit einer nach oben abstehenden Lippe 15.The floor panel 1.1 is characterized by a profiled, by the tread and base surfaces 6, 26 limited side surface 8.1, comprising an abutment surface 7.1, a respect to the abutment surface recessed groove 9 and a projecting beyond the abutment surface 7.1 locking arm 14 with an upwardly projecting lip 15th

Die Nut 9 ist trapezförmig und weist eine gegenüber der Stoßfläche 7.1 zurückversetzte Nutrückwand 10 auf, die parallel zur Stoßfläche 7.1 angeordnet ist und in eine obere, parallel zur Trittfläche 6 verlaufende Nutflanke 13 und eine schräg gerichtete untere Nutflanke 23 ausläuft. Letztere geht wiederum in einen parallel zur Basisfläche 26 liegenden Boden 35 des Verriegelungsarms 14 über, wobei mittig zum Boden 35 ein muldenförmiger Sitz 36 ausgefräst ist.The groove 9 is trapezoidal and has a relation to the abutting surface 7.1 recessed Nutrückwand 10, which is arranged parallel to the impact surface 7.1 and terminates in an upper, parallel to the tread surface 6 groove flank 13 and an obliquely directed lower groove flank 23. The latter in turn goes into a lying parallel to the base surface 26 bottom 35 of the locking arm 14, wherein centered to the bottom 35 a trough-shaped seat 36 is milled.

Die Lippe 15 des Verriegelungsarms 14 ist trapezförmig und verjüngt sich in Richtung Bodenschicht 40 derart, dass an der Lippe eine unter einem scharfen Winkel α zum Boden 35 geneigte Innenfläche 17 gebildet ist. Der Winkel α liegt in vorliegendem Fall zwischen 80° und 85°.The lip 15 of the locking arm 14 is trapezoidal and tapers in the direction of the bottom layer 40 such that an inner surface 17 inclined at a sharp angle α to the bottom 35 is formed on the lip. The angle α is in the present case between 80 ° and 85 °.

Das Fußbodenpaneel 1.2 zeichnet sich durch eine profilierte, durch die Tritt- und Basisflächen 6, 26 begrenzte Seitenfläche 8.2 aus, aufweisend eine Stoßfläche 7.2, eine gegenüber der Stoßfläche 7.2 zurückversetzte Schräge 19 und eine nach unten gerichtete Verriegelungswalze 20. Die Schräge 19 bildet zusammen mit der Verriegelungswalze 20 einen tiefen, scharfen, V-förmigen Übergang 25.The floor panel 1.2 is characterized by a profiled, limited by the tread and base surfaces 6, 26 side surface 8.2, comprising an abutment surface 7.2, opposite the abutment surface 7.2 recessed slope 19 and a downward locking roller 20. The slope 19 forms together with the locking roller 20 a deep, sharp, V-shaped transition 25.

An der Verriegelungswalze 20 ist eine Andrückfläche 21 gefräst, die mit der Trittfläche 6 einen Winkel 60° bildet und annähernd parallel zur Schräge 19 angeordnet ist. Die Verriegelungswalze 20 schließt sich an eine nach unten offene Ausnehmung 37 zur Aufnahme der Lippe 15 des Fußbodenpaneels 1.1 an.On the locking roller 20, a pressing surface 21 is milled, which forms an angle 60 ° with the tread surface 6 and is arranged approximately parallel to the slope 19. The locking roller 20 connects to a downwardly open recess 37 for receiving the lip 15 of the floor panel 1.1.

In Fig. 17 ist eine relativ breite Spalte S zwischen der Verriegelungswalze 20 und der Lippe 15 zu sehen, wobei die beiden Stoßflächen 7.1, 7.2 miteinander kontaktieren. Die Fußbodenpaneele 1.1, 1.2 sind miteinander weder in horizontaler, noch in vertikalen Richtung verriegelt.In Fig. 17 is a relatively wide column S between the locking roller 20 and the lip 15 to see, with the two abutting surfaces 7.1, 7.2 contact each other. The floor panels 1.1, 1.2 are locked with each other neither in the horizontal, nor in the vertical direction.

Eine ähnliche Lage wie bei dem auf den Untergrund 11 verlegten Fußbodenpaneelen 1.1, 1.2 ist der Fig. 7 zu entnehmen. Allerdings ist hier ein separater Verbinder 2.1 (Profil) eingesetzt, derart, dass die Spalte S (vgl. Fig. 17) völlig von einem stegförmigen Fuß 12 des Profils ausgefüllt ist. Die Fußbodenpaneele 1.1, 1.2 bilden samt eingelegtem Profil 2.1 eine Einrichtung 100, bei der das Verbinder-Profil eine Verriegelung in beiden Richtungen (Pfeile X, Y) bewirkt.A similar situation as in the laid on the substrate 11 floor panels 1.1, 1.2 is the Fig. 7 refer to. However, here a separate connector 2.1 (profile) is used, such that the column S (see. Fig. 17 ) is completely filled by a web-shaped foot 12 of the profile. The floor panels 1.1, 1.2 together with the inserted profile 2.1 form a device 100 in which the connector profile brings about a locking in both directions (arrows X, Y).

Das etwa dachrinnenförmige Profil 2.1 (vgl. Figuren 8 und 9) weist einen Querschnitt Q1 auf, auf dem eine teilzylindrische Innenfläche 4, eine ebenso teilzylindrische Außenfläche 28, ein Kopfstück 5 und der Fuß 12 zu erkennen sind. Die Innen- und Außenflächen 4, 28 begrenzen eine rinnenförmige Wandung 3, die vom Kopfstück 5 bis zum Fuß 12 reicht. Das in Fig. 9 gezeigte Profile 2.1 sind relativ kurz und daher für die Schmalseiten der Fußbodenpaneele (vgl. Fig. 16) bestimmt. Seine Länge L entspricht im Wesentlichen dem Ausmaß der Schmalseite oder ist geringfügig kleiner. Ein in Fig. 16 schematisch angedeuteter Fußboden 34 setzt sich aus mehreren oben beschriebenen Fußbodenpaneele 1.1, 1.2 zusammen, die an ihren Schmalseiten über die separaten Verbinder und an Längsseiten über herkömmliche, nicht dargestellte Nut-FederVerbindungen verriegelt sind.The approximately gutter-shaped profile 2.1 (see. FIGS. 8 and 9 ) has a cross-section Q1 on which a part-cylindrical inner surface 4, an equally part-cylindrical outer surface 28, a head piece 5 and the foot 12 can be seen. The inner and outer surfaces 4, 28 define a channel-shaped wall 3, which extends from the head piece 5 to the foot 12. This in Fig. 9 Profiles 2.1 shown are relatively short and therefore for the narrow sides of the floor panels (see. Fig. 16 ) certainly. Its length L corresponds essentially to the extent of the narrow side or is slightly smaller. An in Fig. 16 schematically indicated floor 34 is composed of several above-described floor panels 1.1, 1.2 together, which are locked at their narrow sides on the separate connector and on the long sides over conventional tongue and groove connections, not shown.

Der Fuß 12 weist eine geneigte Seitenfläche 24 auf, deren Neigungswinkel dem Winkel α (vgl. Fig. 2) gleich ist. Ferner weist der Fuß 12 eine Standfläche 27 und einen der Standfläche 27 gegenüberliegenden, oberen Rand 16 auf, der sich an die besagte teilzylindrische Innenfläche 4 anschließt.The foot 12 has an inclined side surface 24, the angle of inclination of the angle α (see. Fig. 2 ) is equal to. Furthermore, the foot 12 has a base 27 and an upper edge 16 opposite the base 27, which adjoins the part-cylindrical inner surface 4.

Ein wesentliches Merkmal des Kopfstücks 5 ist seine obere Gleitfläche 18, die innenseitig von einer weiteren, schrägen Gleitfläche 22 begrenzt ist.An essential feature of the head piece 5 is its upper sliding surface 18, which is bounded on the inside by a further oblique sliding surface 22.

Das in das Fußbodenpaneel 1.1 eingepresste Profil 2.1 ist auch in Figuren 3 und 4 gezeigt. Das Kopfstück 5 steht in Kontakt mit der oberen Nutflanke 13 und ragt über die Stoßfläche 7.1 hinaus. Der Fuß 12 stützt sich mit seiner Standfläche 27 am Boden 35 und mit seiner Seitenfläche 24 an der Innenfläche 17 der Lippe 15 ab. Die Wandung 3 stützt sich wiederum mit ihrem bogenförmigen, unteren Abschnitt bzw. Segment 42 an dem Sitz 36 ab. Auf diese Weise ist das Profil 2.1 am Fußbodenpaneel 1.1 festgelegt und vor dem Herausfallen gesichert.The pressed into the floor panel 1.1 profile 2.1 is also in FIGS. 3 and 4 shown. The head piece 5 is in contact with the upper groove flank 13 and protrudes beyond the impact surface 7.1. The foot 12 is supported with its base 27 at the bottom 35 and with its side surface 24 on the inner surface 17 of the lip 15 from. The wall 3 in turn is supported with its arcuate, lower portion or segment 42 on the seat 36. In this way, the profile 2.1 is fixed to the floor panel 1.1 and secured against falling out.

Wie die Fig. 4 zeigt, ist ein bis zum Segment 42 reichender Schenkel 43 der Wandung 3 flexibel. Da der Schenkel 43 das Kopfstück 5 trägt, ist das letztere auch gegenüber dem Segment 42 verschwenkbar bzw. drehbar angeordnet.As the Fig. 4 shows, reaching up to the segment 42 leg 43 of the wall 3 is flexible. Since the leg 43 carries the head piece 5, the latter is also opposite the segment 42 pivotally mounted or rotatably arranged.

In Figuren 5, 6 und 16 ist das Herabschwenken des Gegenpaneels 1.2 auf den Untergrund 11 gezeigt. Das Gegenpaneel wird um die Schwenkachse A (vgl. Fig. 16) gedreht. In der in Fig. 5 dargestellten Lage fährt die Verriegelungswalze 20 nach unten und gleitet nahezu über die Stoßfläche 7.1 des bereits verlegten Fußbodenpaneels 1.1 bis sie mit ihrer schrägen Andrückfläche 21 gegen das Kopfstück 5 stößt (vgl. Fig. 5). Danach gleitet die Verriegelungswalze 20 mit ihrer Andrückfläche 21 über die in Fig. 8 gezeigten Gleitflächen 22, 18 des Kopfstücks, bis dieses in Richtung Nutrückwand 10 verschwenkt wird und gelangt in die in Fig. 7 gezeigte Verriegelungsstellung, bei der das Kopfstück 5 in den V-förmigen Übergang 25 der Schräge 19 zur Verriegelungswalze 20 einspringt.In FIGS. 5, 6 and 16 is shown the pivoting down of the Gegenpaneels 1.2 on the substrate 11. The Gegenpaneel is about the pivot axis A (see. Fig. 16 ) turned. In the in Fig. 5 shown position, the locking roller 20 moves down and slides almost over the abutment surface 7.1 of the already laid floor panel 1.1 until it abuts with its oblique pressing surface 21 against the head piece 5 (see. Fig. 5 ). Thereafter, the locking roller 20 slides with its Andrückfläche 21 over in Fig. 8 shown sliding surfaces 22, 18 of the head piece, until it is pivoted in the direction Nutrückwand 10 and enters the in Fig. 7 shown locking position in which the head piece 5 in the V-shaped transition 25 of the slope 19 to the locking roller 20.

Dabei unterliegt das Profil 2.1 beim Herabschwenken des Gegenpaneels 1.2 in Richtung Boden 35 des bereits verlegten Fußbodenpaneels 1.1 einer Torsion, bei der das Kopfstück 5 nach und nach derart gedreht wird, dass zuerst ein der Schwenkachse A des Fußbodenpaneels zugewandtes Ende 31 und anschließend ein zweites Ende 32 des Profils komplett unter die obere Nutflanke 13 gelangt. Unter Torsion soll in vorliegendem Fall die Verwindung nur eines Teils des Profils, nämlich des Schenkels 43 und des Kopfstücks 5 verstanden werden, während der Fuß 12 in seiner Lage unbeweglich verbleibt.In this case, the profile is 2.1 when swinging down the Gegenpaneels 1.2 in the direction of the floor 35 of the already laid floor panel 1.1 torsion, in which the head piece 5 is gradually rotated so that first one of the pivot axis A of the floor panel facing end 31 and then a second end 32 of the profile completely passes under the upper groove flank 13. Under torsion in the present case, the twisting of only a part of the profile, namely the leg 43 and the head piece 5 should be understood while the foot 12 remains immobile in its position.

Die Fig. 10 zeigt einen Verbinder 2.2, der ähnlich, wie der Verbinder 2.1 aufgebaut ist mit dem Unterschied, dass anstelle eines stegförmigen ein massiver Fuß 30 vorgesehen ist. Dies zeigt ein Querschnitt Q2 des Profils, bei dem die Standfläche 27 des massiven Fußes 30 bis zum Segment 42 reicht. Das Profil 2.2 kann anstelle des Profils 2.1 eingesetzt sein (nicht dargestellt).The Fig. 10 shows a connector 2.2, which is similar to the connector 2.1 is constructed with the difference that instead of a web-shaped a solid foot 30 is provided is. This shows a cross section Q2 of the profile, in which the footprint 27 of the solid foot 30 extends to the segment 42. The profile 2.2 can be used instead of the profile 2.1 (not shown).

Eine andere ähnliche Ausführungsform (Bezugszahl 2.3) zeigt ein Querschnitt Q3 des Profils in Fig. 11. Die Wandung 3 weist an ihrem mittigen Segment 42 eine ebene untere Fläche 29 auf. Ein nicht dargestellter Boden des Verriegelungsarms 14 verfügt über einen angepassten Sitz für das Profil 2.3 (nicht dargestellt).Another similar embodiment (reference number 2.3) shows a cross section Q3 of the profile in FIG Fig. 11 , The wall 3 has at its central segment 42 a flat lower surface 29. An unillustrated bottom of the locking arm 14 has an adapted seat for the profile 2.3 (not shown).

Die Fig. 12 zeigt einen Querschnitt Q4 eines weiteren Profils 2.4, bei dem der massive Fuß 30 über einen unteren Basisteil 44 des Profils sich an den bogenförmigen, verschwenkbaren Schenkel 43 anschließt, derart, dass die untere, ebene Standfläche 27 bis zum besagten Schenkel 43 reicht. Gemäß Fig. 13 ist das Profil 2.4 mit seiner Standfläche 27 auf den ebenso flachen Boden 35 des Verriegelungsarms 14 gelegt. Die Breite des Bodens 35 ist der der Standfläche 27 gleich. So ist der Schenkel 43 um einen Übergangsbereich 45 des Profils, der dem Übergang des Bodens 35 in die schräge Nutflanke 23 entspricht, verschwenkbar.The Fig. 12 shows a cross section Q4 of another profile 2.4, in which the solid foot 30 connects via a lower base portion 44 of the profile to the arcuate, pivotable leg 43, such that the lower, flat base 27 extends to the said leg 43. According to Fig. 13 the profile 2.4 is placed with its base 27 on the flat bottom 35 of the locking arm 14. The width of the bottom 35 is equal to the base 27. Thus, the leg 43 is pivotable about a transition region 45 of the profile, which corresponds to the transition of the bottom 35 in the inclined groove flank 23.

Schließlich zeigt die Fig. 14 einen Querschnitt Q5 eines anderen Profils 2.5, welches dem Profil 2.4 nahezu identisch ist. Der Übergangsbereich 45 des Profils ist derart abgestuft, dass sein unterer Basisteil 44 zum ebenen Boden 35 kompatibel ist (vgl. Fig. 15). Der Boden 35 geht über eine Abstufung 33 in die untere, schräge Nutflanke 23 über.Finally, the shows Fig. 14 a cross section Q5 of another profile 2.5, which is almost identical to the profile 2.4. The transition region 45 of the profile is stepped such that its lower base part 44 is compatible with the flat bottom 35 (cf. Fig. 15 ). The bottom 35 goes over a gradation 33 in the lower, sloping groove edge 23 over.

Claims (7)

  1. Floor panel (1.1) having an arrangement (100) for connection to at least one further floor panel (1.2) of the same type on a substrate (11), wherein
    - the floor panels (1.1, 1.2) have a first and a second profiled side surface (8.1; 8.2) respectively, located oppositely, on which a respective abutment surface (7.1; 7.2) is disposed which lies perpendicular to a walking surface (6) or a base surface (26) of the floor panel;
    - the abutment surface (7.1) of the first side surface (8.1) merges into a groove (9) extending in parallel with the walking surface (6) along the side surface, which groove is defined towards the walking surface (6) by a groove flank (13);
    - a locking arm (14) protrudes beyond the abutment surface (7.1) of the first side surface (8.1) and has a base (35) and runs out into an approximately trapezoidal lip (15) directed towards the walking surface (6), which lip in turn has an inner surface (17) facing the groove (9);
    - in which an elongate, at least partially flexible, separate connector (2.1; 2.2; 2.3; 2.4; 2.5) is let into the groove (9) and, in the laid condition, cooperates with the second side surface (8.2) of an opposing floor panel,
    - wherein the connector (2.1; 2.2; 2.3; 2.4; 2.5) in the undeformed condition has a cross-section approaching a gutter shape and has a curved wall (3);
    - the wall (3) - when seen in a cross-section (Q1; Q2; Q3; Q4) of the connector - merges with a part-cylindrical inner surface (4) at an edge of this inner surface into a head piece (5) and on the other hand into a foot (12; 30) which has a free side surface (24) and a standing surface (27);
    - in the condition where the connector (2.1; 2.2; 2.3; 2.4; 2.5) is fitted into the groove, the head piece (5) at least partially presses against a first groove flank (13) of the groove (9);
    - the second side surface (8.2) of the floor panel (1.1, 1.2) has a locking roll (20) engaging into the inner chamber, clamped by the inner surface of the connector (2.1; 2.2; 2.3; 2.4; 2.5), when the floor panels (1.1, 1.2) are being fitted together, which locking roll causes cooperation with the connector (2.1; 2.2; 2.3; 2.4; 2.5);
    characterised in that
    - the groove (9) has a planar groove rear wall (10) set back with respect to the abutment surface (7.1) of the first side surface,
    - wherein the head piece (5) is disposed on a flexible limb (43) of the connector (2.1; 2.2; 2.3; 2.4; 2.5) so that, when floor panels (1.1, 1.2) are being fitting together the head piece (5) can be pivoted in the direction of the groove rear wall (10);
    - the inner surface (17) of the lip (15) is undercut with respect to the base (35) so that, with its side surface (24) and with its standing surface (27) when the connector is in the mounted condition, the foot (12; 30) contacts the said inner surface (17) and the base (35) of the locking arm (14) before and after the two floor panels (1.1, 1.2) are fitted together.
  2. Floor panel as claimed in claim 1, characterised in that when the floor panel (1.2) is pivoted downwards in the direction of the base (35) of the already-laid floor panel (1.1) the foot (12; 30) of the connector remains immoveable.
  3. Floor panel as claimed in claim 1, characterised in that the base (35) is adjoined by a second groove flank (23) extending in an inclined manner and emerging from the groove rear wall (10).
  4. Floor panel as claimed in claim 1, characterised in that, centrally with respect to the base (35), at least one depression-like seat (36) extending in parallel with the groove (9) is incorporated, a part of the inserted connector (2.1; 2.2; 2.3) nestling against this seat.
  5. Floor panel as claimed in claim 1, characterised in that
    - the abutment surface (7.2) of the second side surface (8.2) of the floor panel (1.2) cooperating with the connector (2.1; 2.2; 2.3; 2.4; 2.5) merges into the locking roll (20) via an incline (19) set back with respect to the said abutment surface (7.2),
    - and that the incline (19) forms a set-back transition (25) with the locking roll (20), which transition serves to support the head piece (5) after insertion of the locking roll (20) into the connector.
  6. Floor panel as claimed in claim 1, characterised in that the foot (12) is in the form of a bar.
