Description

Die Erfindung bezieht sich auf einen Fußbodenbelag mit einer Mehrzahl von Fußbodenpaneelen der im Oberbegriff von Anspruch 1 erläuterten Art.The invention relates to a floor covering with a plurality of floor panels of the type explained in the preamble of claim 1.

Ein derartiger Fußbodenbelag ist aus der JP-A-09088315 bekannt, die einen Fußbodenbelag aus einer Mehrzahl von Fußbodenpaneelen beschreibt, die über Verriegelungselemente unter Ausbildung einer Ausnehmung an der Unterseite miteinander verbunden sind. In die Unterseite sind zwischen den Verriegelungselementen weitere Ausnehmungen in Form von Schlitzen vorgesehen, die sich in das Kernmaterial hineinerstrecken.Such a floor covering is from the JP-A-09088315 known, which describes a floor covering of a plurality of floor panels, which are interconnected via locking elements to form a recess at the bottom. In the bottom, further recesses in the form of slots are provided between the locking elements, which extend into the core material.

Die US 2 088 238 beschreibt einen Fußbodenbelag aus einzelnen Fußbodenpaneelen, die an ihrer Unterseite mit einer oder mehreren Ausnehmungen versehen sind, wobei sich weitere Ausnehmungen beim Zusammenfügen der Fußbodenpaneele ergeben. Diese Ausnehmungen sind jedoch nicht für eine Trittschalldämmung ausgelegt, sondern werden beim Verlegen im Fußbodenbelag mit Kleber verfüllt, der eine gute Schallbrücke bildet.The US 2,088,238 describes a floor covering of individual floor panels, which are provided on its underside with one or more recesses, resulting in further recesses in the assembly of the floor panels. However, these recesses are not designed for a footfall sound insulation, but are filled when laying in the floor covering with adhesive, which forms a good sound bridge.

JP 2003-147950 beschreibt ein Fußbodenmaterial mit einem Kern (Matrix 2) aus einem weichen Kunststoffmaterial. Das Fußbodenmaterial soll schalldämmend wirken, was durch die Herstellung des Kerns mit einer Federhärte von sechzig Grad oder weniger bewirkt werden soll. Zur Schalldämmung sind weiterhin eine Vielzahl von Schlitzen vorgesehen, die sich von der Rückseite her in die Matrix erstrecken. JP 2003-147950 describes a floor material with a core (matrix 2) made of a soft plastic material. The floor material should have a soundproofing effect, which should be achieved by making the core with a spring rate of sixty degrees or less. For sound insulation, a plurality of slots are further provided which extend from the back into the matrix.

FR 2 278 876 beschreibt eine Verbindungseinrichtung zum Verbinden von Fliesen oder Platten aus Kautschuk oder Kunststoff für die verschiedensten Anwendungen. Die Platten sind an jeweils zwei gegenüberliegenden Seiten mit korrespondierenden, mechanischen Verriegelungselementen versehen, um benachbarte Platten verriegelnd an einander befestigen zu können. Die Verriegelungselemente sind so ausgebildet, dass sie ausnehmungsfrei in einander passen müssen, damit an der Trittfläche kein Spalt zwischen zwei benachbarten Platten auftritt. Eine Schalldämmung wird nicht angesprochen. FR 2 278 876 describes a connecting device for connecting tiles or sheets of rubber or plastic for a variety of applications. The plates are provided on each of two opposite sides with corresponding mechanical locking elements in order to be able to lock adjoining plates to one another. The locking elements are designed so that they must fit without recesses in each other, so that no gap between two adjacent plates occurs at the tread. A sound insulation is not addressed.

DE 33 39 701 beschreibt eine schalldämmende und schalldämpfende Platte zur Bildung oder zur Verkleidung von Wänden und Decken. Die Platte besteht aus einem erhärteten Gemisch aus Fasern und Bindemittel und weist an ihrer der Schallquelle zugewandten Fläche eine Vielzahl von Löchern auf. Die Löcher verlaufen in einem spitzen Winkel zur Fläche der Platte. Derartige Platten, deren Löcher der Schallquelle, d. h. der Innenseite des Raums, in dem sie verwendet werden, zugewandt sind, sind einerseits für eine Raumschalldämmung ausgelegt und andererseits für Fußböden völlig unbrauchbar, da sich ihre Öffnungen sofort mit Schmutz zusetzen würden. Dies beeinträchtigt sowohl das Erscheinungsbild als auch ihre Wirkung als Schallleitungs-Unterbrecher. DE 33 39 701 describes a sound-absorbing and sound-absorbing panel for forming or covering walls and ceilings. The plate consists of a hardened Mixture of fibers and binder and has at its the sound source facing surface on a plurality of holes. The holes are at an acute angle to the surface of the plate. Such plates, whose holes of the sound source, ie the inside of the room in which they are used, are facing, on the one hand designed for a room sound insulation and on the other hand completely unsuitable for floors, since their openings would clog up immediately with dirt. This affects both the appearance and its effect as a sound conductor breaker.

US 5 879 781 beschreibt ein Fußbodenmaterial mit Schall reduzierenden Eigenschaften. Das Fußbodenpaneel, in Form eines Laminats, hat einen Kern aus Holzmaterial, in den von der Bodenseite her eine Vielzahl von Bohrungen eingebracht wurden, die über die gesamte Bodenfläche verteilt sind. Die Bohrungen werden durch eine rückwärtige Deckschicht abgedeckt und können gegebenenfalls mit Materialien mit hohen Schalldämpfungseigenschaften, wie beispielsweise Gummi, Kork, Schaum oder Filz, gefüllt sein. Das Bodenlaminat enthält Verriegelungseinrichtungen die wiederum so ausgebildet sind, dass sich an der Bodenseite kein Spalt bilden kann, wenn benachbarte Laminatpaneele korrekt mit einander verbunden sind. U.S. 5,879,781 describes a floor material with sound reducing properties. The floor panel, in the form of a laminate, has a core made of wood material into which a large number of holes have been made from the bottom side, which are distributed over the entire floor area. The holes are covered by a back cover layer and may optionally be filled with materials with high sound damping properties such as rubber, cork, foam or felt. The floor laminate includes locking means which in turn are designed so that no gap can form on the bottom side when adjacent laminate panels are correctly connected to each other.

Ein aus der EP 1 264 946 bekanntes Fußbodenpaneel enthält eine Schalldämmung in Form von wenigstens einer Schalldämmschicht, die an der der Trittseite zugewandten Seite des Kerns angeordnet ist. Die Schalldämmschicht besteht aus einem dünnen, weichen, federnd nachgiebigen Material, insbesondere aus Kunststoff und muss bei der Herstellung des Fußbodenpaneels in das Laminat eingearbeitet werden, was relativ aufwendig ist.One from the EP 1 264 946 Known floor panel contains a sound insulation in the form of at least one sound insulation layer, which is arranged on the side facing the side of the kick of the core. The sound insulation layer consists of a thin, soft, resilient material, in particular of plastic and must be incorporated in the manufacture of the floor panel in the laminate, which is relatively expensive.

Die WO 99/00242 zeigt ein Fußbodenpaneel in rechteckiger Form, das einen Kern aus Massivholz und zwei auf der Ober- und der Unterseite des Kerns angeordnete, dünnere Platten, ebenfalls aus Massivholz, enthält. Das Fußbodenpaneel ist schallgedämmt, wobei in einem ersten Ausführungsbeispiel Schalldämmschichten zwischen den Kern und die den Kern beidseitig bedeckenden Platten, mit den bereits beschriebenen Nachteilen, zwischengelegt sind.The WO 99/00242 shows a floor panel in rectangular shape, which contains a core of solid wood and two arranged on the top and bottom of the core, thinner plates, also made of solid wood. The floor panel is sound-insulated, wherein in a first embodiment, sound insulation layers between the core and the core on both sides covering plates, with the disadvantages already described, are interposed.

In einem weiteren Ausführungsbeispiel sind diejenigen Seiten des Kerns, die den benachbarten, dünneren Platten zugewandt sind, mit Rillen versehen, durch die die Kontaktfläche von Holz zu Holz verringert wird, was eine Schalldämmung bewirken soll. Dadurch wird jedoch auch die kraftübertragende Fläche zwischen den Holzschichten verringert, was im Extremfall zum Abflachen der zwischen den Rillen liegenden Spitzen in Fußbodenbereichen führen kann, die besonders stark begangen werden, so dass sich dort der Fußboden leicht absenkt.In a further embodiment, those sides of the core which face the adjacent, thinner plates are provided with grooves, by means of which the contact surface of wood to wood is reduced, which is intended to effect sound insulation. As a result, however, the force-transmitting surface between the layers of wood is reduced, which can lead to flattening of lying between the grooves peaks in floor areas in extreme cases, which are committed particularly strong, so that there slightly lowers the floor.

Weiterhin sind im Kern längsverlaufende Nuten eingearbeitet, und zwar abwechselnd von der Ober- und der Unterseite, wobei sich die Nuten bis über die Hälfte der Dicke des Kerns in diesen Kern hineinerstrecken. Durch diese Nuten soll das Quellen und Schrumpfen des Holzes bei Änderungen der Feuchtigkeit ausgeglichen werden, so dass das sogenannte Arbeiten des Holzes nicht zu Verwerfungen im Fußbodenbelag führt. Diese Nuten erstrecken sich jedoch nicht bis zur Unterseite, sondern sind durch die dünneren Holzplatten abgedeckt, die als Schallbrücken wirken. Außerdem sind die beschriebenen Fußbodenpaneele aus Massivholz für eine Verleimung ausgelegt, wobei die sich zwischen den Paneelen ersteckenden Leimlagen ebenfalls schalldämmend wirken, so dass an eine zusätzliche Schalldämmung geringere Anforderungen zu stellen sind.Furthermore, longitudinally extending grooves are incorporated in the core, alternately from the top and the bottom, with the grooves extending into this core to over half the thickness of the core. Through these grooves, the swelling and shrinkage of the wood to be compensated for changes in humidity, so that the so-called working of the wood does not lead to dislocations in the floor covering. However, these grooves do not extend to the bottom, but are covered by the thinner wood panels, which act as sound bridges. In addition, the described solid wood floor panels are designed for gluing, wherein the glue layers which extend between the panels also have a sound-damping effect, so that lower requirements must be imposed on additional sound insulation.

Schließlich ist es gängige Praxis, schallabsorbierende Schichten aus (Nadel-)Filz, Kunststoff, Gummi oder dgl. beim Verlegen unter die Paneele einzubringen oder bei der Herstellung gegebenenfalls mit den Paneelen zu verkleben, was recht aufwändig ist.Finally, it is common practice to introduce sound-absorbing layers of (needle) felt, plastic, rubber or the like. When laying under the panels or in the manufacture optionally with the panels to glue, which is quite complex.

WO 03/087498 beschreibt einen Fußbodenbelag nach dem Oberbegriff der Ansprüche 1 und 2. WO 03/087498 describes a floor covering according to the preamble of claims 1 and 2.

Der Erfindung liegt somit die Aufgabe zugrunde, ein Fußbodenpaneel mit einer einfach herzustellenden und wirksamen Trittschalldämmung bereitzustellen.The invention is therefore an object of the invention to provide a floor panel with a simple to produce and effective impact sound insulation.

Die Aufgabe wird durch die in den Ansprüchen 1 und 2 angegebenen Merkmale gelöst.The object is solved by the features specified in claims 1 and 2.

Es hat sich herausgestellt, dass es überraschenderweise möglich ist, mit einer einzigen oder einer Reihe hintereinanderliegender, sich von der Unterseite bis in den Kern hineinreichenden Ausnehmungen in Verbindung mit einer durch die Verriegelung selbst gebildeten Ausnehmung eine wirksame Trittschalldämmung zu erreichen, und zwar für Fußbodenpaneele mit mechanischen Verriegelungssystemen, d.h. ohne Leimschicht zwischen den Paneelen. In praktischen Versuchen wurde eine signifikante Reduzierung des Trittschalls um beispielsweise 3dB festgestellt.It has been found that it is surprisingly possible, with a single or a series of successive, extending from the bottom to the core reaching recesses in conjunction with a recess formed by the locking itself effective footfall sound insulation, namely for floor panels with mechanical locking systems, ie without glue layer between the panels. In practical experiments, a significant reduction in impact sound was detected by, for example, 3dB.

Vorteilhafte Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.Advantageous developments of the invention can be found in the dependent claims.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen näher erläutert. Es zeigen:

Fig. 1 zeigt in perspektivischer Darstellung ein erstes Ausführungsbeispiel eines erfindungsgemäßen Fußbodenpaneels 1, das eine Trittseite 2 und eine in Fig. 1 verdeckte Unterseite 3, die als Auflagefläche auf einem Fußbodenuntergrund dient, sowie einen zwischen der Unterseite 3 und der Trittseite 2 angeordneten Kern 4 aufweist. Fig. 1 shows a perspective view of a first embodiment of a floor panel 1 according to the invention, which has a tread side 2 and a in Fig. 1 concealed bottom 3, which serves as a support surface on a floor surface, and arranged between the bottom 3 and the tread side 2 core 4.

Das dargestellte Fußbodenpaneel 1 ist Teil eines Laminatfußbodens, wobei die Trittfläche 2 durch eine Laminatschicht gebildet wird, die trittfest, beschädigungs- und verschmutzungsunempfindlich sowie dekorativ ist. Der Kern 4 besteht aus einem industriell hergestellten Holzfaserwerkstoff, nämlich einer MDF/HDF-Platte . Die Unterseite 3 ist die Unterseite des Kerns 4 aus dem Material des Kerns oder kann durch eine auf den Kern auflaminierte Schutz- oder Ausgleichsschicht (hier nicht gezeichnet) gebildet werden.The floor panel 1 shown is part of a laminate floor, wherein the tread surface 2 is formed by a laminate layer that is resistant to tread, damage and contamination insensitive and decorative. The core 4 consists of an industrially produced wood fiber material, namely an MDF / HDF board. The underside 3 is the underside of the core 4 made of the material of the core or may be formed by a protective or leveling layer (not shown here) laminated to the core.

Das hier gezeigte Fußbodenpaneel 1 hat eine rechteckige Form und ist relativ klein, wobei die Breite B zwischen 5 cm bis 15 cm, bevorzugt 8 cm, und die Länge L zwischen 20 cm und 80 cm, bevorzugt 60 cm, beträgt. Das Fußbodenpaneel hat somit zwei gegenüberliegende lange Seiten 5a und 5b sowie zwei gegenüberliegende kurze Seiten 6a bzw. 6b. An wenigstens den langen Seiten 5a, 5b befinden sich korrespondierende, mechanische Verriegelungselemente 7a bzw. 7b, mit denen benachbarte Fußbodenpaneele über eine Rastverbindung verriegelt werden können. Das Verriegelungselement 7a enthält zu diesem Zweck eine Leiste 8 mit einer vorstehenden Nase 8a, die über eine Rille 9 nach innen begrenzt ist. Das Verriegelungselement 7b enthält eine Vertiefung 10 zum Aufnehmen der Leiste 8 mit einer Hinterschneidung 10a zum Aufnehmen der Nase 8a, die nach außen hin durch eine Leiste 11 begrenzt wird, die in der Rille 9 aufgenommen werden kann. Auf diese Weise können benachbarte Fußbodenpaneele mit ihren langen Seiten über eine Schnapp- bzw. Rastverbindung miteinander verriegelt werden, wobei es lediglich erforderlich ist, die beiden Paneele mit ihren langen Seiten im Winkel so aneinander zu setzen, dass die Nase 8a in die Vertiefung 10 eintaucht, und anschließend die beiden Paneele fluchtend und eben miteinander auszurichten, wodurch sich die Nase 8a in die Hinterschneidung 10a bewegt. Dabei sind die Verriegelungselemente 7a, 7b in ihren Abmessungen, insbesondere ihrer Breite b, so aufeinander abgestimmt, dass sich die beiden Paneele parallel zu den kurzen Seiten 6a nicht gegeneinander verschieben können.The floor panel 1 shown here has a rectangular shape and is relatively small, wherein the width B between 5 cm to 15 cm, preferably 8 cm, and the length L between 20 cm and 80 cm, preferably 60 cm. The floor panel thus has two opposite long sides 5a and 5b and two opposite short sides 6a and 6b, respectively. At least the long sides 5a, 5b are corresponding, mechanical locking elements 7a and 7b, with which adjacent floor panels can be locked via a snap-in connection. The locking element 7a contains for this purpose a bar 8 with a protruding nose 8a, which is bounded by a groove 9 inwards. The locking member 7b includes a recess 10 for receiving the strip 8 with an undercut 10a for receiving the nose 8a, which is bounded outwardly by a bar 11 which can be received in the groove 9. In this way, adjacent floor panels with their long sides be locked together via a snap or locking connection, wherein it is only necessary to set the two panels with their long sides at an angle to each other so that the nose 8a dips into the recess 10, and then the two panels in alignment and just together to align, causing the nose 8a moves into the undercut 10a. In this case, the locking elements 7a, 7b in their dimensions, in particular their width b, so matched to one another that the two panels parallel to the short sides 6a can not move against each other.

Im dargestellten Ausführungsbeispiel sind auch die beiden kurzen Seiten 6a, 6b mit korrespondierenden Verriegelungselementen 12a, 12b versehen, wobei das Verriegelungselement 12a dem Verriegelungselement 7b entspricht und das Verriegelungselement 12b analog dem Verriegelungselement 7a entspricht, jedoch nicht die Nase aufweist, damit die Paneele mit ihren kurzen Seiten durch einfaches Niederdrücken miteinander verbunden werden können, was die Verlegung erleichtert.In the illustrated embodiment, the two short sides 6a, 6b are provided with corresponding locking elements 12a, 12b, wherein the locking element 12a corresponds to the locking element 7b and the locking element 12b analogous to the locking element 7a corresponds, but does not have the nose, so that the panels with their short Pages can be connected by simply pressing down, which facilitates the installation.

Die Verbindung über die Verriegelungselemente 7a, 7b und 12a, 12b erfordert keinen Leimauftrag.The connection via the locking elements 7a, 7b and 12a, 12b requires no glue application.

Das erfindungsgemäße Fußbodenpaneel 1 ist mit einer einfach herstellbaren und trotzdem wirksamen Schalldämmung, insbesondere gegen Trittschall, versehen, die in Form wenigstens einer Ausnehmung 13 vorgesehen ist, die sich von der Unterseite 3 in das Paneel hineinerstreckt, wobei die Unterseite 3 außerhalb der Ausnehmung 13 eben und flach ist. Die Schalldämmung wird im dargestellten Ausführungsbeispiel durch eine einzige Ausnehmung 13 bewirkt, die sich in Form einer Nut von einer kurzen Seite 6a durchgehend bis zur zweiten kurzen Seite 6b erstreckt. Die Ausnehmung 13 hat eine Tiefe t, die so bemessen ist, dass sich die Ausnehmung 13 von der Unterseite 3 bis über ein Drittel bis zur Hälfte der Dicke D des Kerns 4 in diesen hineinerstreckt. Die Ausnehmung 13 ist zur Unterseite 3 hin offen und sollte dies auch bleiben. Es ist allenfalls möglich, eine dünne, keine Schallbrücke bildende Schicht auf die Unterseite 3 so aufzubringen, dass die Ausnehmung 13 abgedeckt wird. Die Ausnehmung 13 sollte jedoch auf jeden Fall ihre Schallwellen unterbrechende Funktion nicht einbüßen.The floor panel 1 according to the invention is provided with an easily produced and yet effective sound insulation, especially against impact sound, which is provided in the form of at least one recess 13 which extends from the bottom 3 in the panel, the bottom 3 outside the recess 13 flat and is flat. The sound insulation is effected in the illustrated embodiment by a single recess 13 which extends in the form of a groove from a short side 6a continuously to the second short side 6b. The recess 13 has a depth t, which is dimensioned so that the recess 13 extends from the bottom 3 to over a third to half of the thickness D of the core 4 in this hineinerstreckt. The recess 13 is open to the bottom 3 and should remain so. At best, it is possible to apply a thin layer, which does not form a sound bridge, to the underside 3 in such a way that the recess 13 is covered. However, the recess 13 should definitely not lose its sound-wave interrupting function.

Die Ausnehmung 13 hat eine Breite s zwischen 1 und 10 mm und erstreckt sich etwa in der Mitte zwischen den langen Seiten 5a, 5b, parallel zu diesen und bis in den Bereich der Verriegelungselemente 12a, 12b der kurzen Seiten 6a, 6b. Dabei kann von der äußeren Leiste des Verriegelungselementes 12a ein kleiner Verbindungssteg 14 stehen bleiben, der den Zusammenhalt verbessert.The recess 13 has a width s between 1 and 10 mm and extends approximately in the middle between the long sides 5a, 5b, parallel to them and into the region of the locking elements 12a, 12b of the short sides 6a, 6b. In this case, from the outer strip of the locking element 12a a small connecting web 14 remain standing, which improves the cohesion.

Fig. 4 zeigt einen Teil eines Fußbodenbelags 15, der aus einer Mehrzahl von Fußbodenpaneelen 1 gemäß den Fig. 1 bis 3 hergestellt wurde. Fig. 4 zeigt die Unterseite des Fußbodenbelags 15 und eine parallele und jeweils um die Hälfte versetzte Anordnung der Fußbodenpaneele 1, in Form eines regelmäßigen Schiffsboden-Verbandes. Wie Fig. 4 zu entnehmen ist, sind die Verriegelungselemente 7a, 7b sowie 12a, 12b benachbarter Fußbodenpaneele so ausgebildet, dass sich auf der Unterseite des Fußbodenbelags zwischen benachbarten Paneelen Nuten 16 zwischen den langen Seiten und Nuten 17 zwischen den kurzen Seiten bilden, während die Trittseiten 2 benachbarter Paneele fast fugenlos aneinander anstoßen. Auf diese Weise werden, bei einer Breite B der Fußbodenpaneele 1 von 8 cm aller 4 cm in Längsrichtung durchlaufende Nuten 13, 16 gebildet, die eine wirksame Trittschalldämmung bieten. Zusätzlich dienen auch die Nuten 17 zwischen benachbarten kurzen Seiten der Trittschalldämmung. Fig. 4 shows a part of a floor covering 15, which consists of a plurality of floor panels 1 according to the Fig. 1 to 3 was produced. Fig. 4 shows the bottom of the floor covering 15 and a parallel and offset by half each arrangement of the floor panels 1, in the form of a regular ship's floor bandage. As Fig. 4 it can be seen, the locking elements 7a, 7b and 12a, 12b adjacent floor panels are formed so that form on the bottom of the floor covering between adjacent panels grooves 16 between the long sides and grooves 17 between the short sides, while the tread sides 2 adjacent panels almost seamlessly abut each other. In this way, at a width B of the floor panels 1 of 8 cm of all 4 cm longitudinally continuous grooves 13, 16 are formed, which provide an effective impact sound insulation. In addition, the grooves 17 serve between adjacent short sides of the impact sound insulation.

Fig. 5 zeigt ein weiteres Ausführungsbeispiel eines Fußbodenbelags 18 aus einem weiteren Ausführungsbeispiel von erfindungsgemäß ausgebildeten Fußbodenpaneelen 1' im Fischgrätverbund, wiederum mit Blick auf die Unterseiten 3. Fig. 5 shows a further embodiment of a floor covering 18 from a further embodiment of inventively embodied floor panels 1 'in herringbone composite, again with a view of the lower sides. 3

Das Fußbodenpaneel 1' unterscheidet sich vom Fußbodenpaneel 1 lediglich durch eine abweichende Art der Ausnehmung, wobei hier eine Vielzahl einzelner, schlitzförmiger Ausnehmungen 19 in Reihenanordnung hintereinander vorgesehen sind. Ansonsten entspricht die Ausgestaltung des Fußbodenpaneels 1' dem Fußbodenpaneel 1, wobei insbesondere die Reihenanordnung der Ausnehmungen 19 ebenfalls mittig und parallel zwischen den langen Seiten 5a und 5b angeordnet ist und von einer kurzen Seite 6a zur gegenüberliegenden kurzen Seite 6b reicht. Auch bei der Fischgrätanordnung des Bodenbelags 18 bilden sich Nuten 20 zur Trittschalldämmung zwischen den langen und kurzen Seiten.The floor panel 1 'differs from the floor panel 1 only by a different type of recess, in which case a plurality of individual, slot-shaped recesses 19 are provided in series one behind the other. Otherwise, the embodiment of the floor panel 1 'corresponds to the floor panel 1, wherein in particular the row arrangement of the recesses 19 is also arranged centrally and parallel between the long sides 5a and 5b and extends from a short side 6a to the opposite short side 6b. Even with the herringbone arrangement of the floor covering 18, grooves 20 form the impact sound insulation between the long and short sides.

Die Erfindung ist durch die Ansprüche bestimmt. Hiernach werden Ausführungsformen beschrieben, welche nicht in dem Schutzbereich der Ansprüche fallen.The invention is defined by the claims. Hereinafter, embodiments will be described which do not fall within the scope of the claims.

In Abwandlung der beschriebenen und gezeichneten Ausführungsbeispiele können die Ausnehmungen in ihrer Form, Größe (Tiefe, Breite, Länge), Anordnung und Anzahl variiert werden. So können beispielsweise für größere Fußbodenpaneele zwei oder mehr durchlaufende Ausnehmungen vorgesehen sein, oder eine Vielzahl von Ausnehmungen in Reihen, in einer Diamantform oder in einer anderen Anordnung über die Unterseiten verteilt werden. Die Ausnehmungen müssen nicht unbedingt parallel zu den langen Seiten, sondern können auch entlang der kurzen Seiten oder regellos angeordnet sein. Die Ausnehmungen müssen nicht unbedingt als Nuten, sondern können beispielsweise als Kerben, Sacklöcher, Einschnitte oder dgl. ausgebildet sein. Die Fußbodenpaneele müssen nicht unbedingt an allen vier Seiten mit Verriegelungselementen versehen sein, insbesondere bei einer Schiffsboden-Verlegung kann es beispielsweise ausreichen, nur die langen Seiten mit diesen Verriegelungselementen zu versehen. Die Form und Wirkungsweise der Verriegelungselemente kann ebenfalls verändert werden. So kann die Erfindung bei Fußbodenpaneelen mit allen gängigen Verriegelungssystemen oder zu verleimende Fußbodenpaneele eingesetzt werden. Die Erfindung ist weiterhin auf Fußbodenpaneele anderer Formen und Abmessungen anwendbar, einschließlich normal- oder standardgroßer Paneele von 120 x 20 cm oder Paneele mit Gehrungsschnittanschluss, quadratisch oder sechseckig oder dgl.. Auch die Materialauswahl für das Fußbodenpaneel kann an veränderte Einsatzzwecke angepasst werden. Schließlich sind alle Ausführungsbeispiele der Fußbodenpaneele für alle gängigen Verlegungsmuster geeignet. In a modification of the described and illustrated embodiments, the recesses in their shape, size (depth, width, length), arrangement and number can be varied. For example, for larger floor panels, two or more continuous recesses may be provided, or a plurality of recesses may be distributed in rows, in a diamond shape, or in another arrangement over the undersides. The recesses do not necessarily have to be parallel to the long sides, but can also be arranged along the short sides or randomly. The recesses do not necessarily have to be in the form of grooves, but can be designed, for example, as notches, blind holes, cuts or the like. The floor panels need not necessarily be provided on all four sides with locking elements, especially in a ship floor laying, for example, it may be sufficient to provide only the long sides with these locking elements. The shape and operation of the locking elements can also be changed. Thus, the invention can be used in floor panels with all common locking systems or to be glued floor panels. The invention is also applicable to floor panels of other shapes and dimensions, including standard or standard 120 x 20 cm panels or mitered panels, square or hexagonal or the like. Also, the material selection for the floor panel can be adapted to changing uses. Finally, all embodiments of the floor panels are suitable for all common installation patterns.
