Description

Die Erfindung betrifft ein Paneel, umfassend eine Paneeloberseite und eine Paneelunterseite sowie wenigstens vier Paneelkanten, die sich paarweise gegenüberliegen, mit an den Paneelkanten paarweise vorgesehenen komplementären Halteprofilen, die derart zueinanderpassen, dass gleichartige Paneele aneinander befestigbar sind, wobei wenigstens eines der Halteprofilpaare mit Hakenprofilen versehen ist, nämlich an einer Paneelkante mit einem Aufnahmehaken und an der gegenüberliegenden Paneelkante mit einem Arretierhaken.The invention relates to a panel comprising a panel top and a panel underside as well as at least four panel edges, which lie opposite one another in pairs, with complementary retaining profiles provided in pairs on the panel edges, which match one another in such a way that similar panels can be fastened to one another, at least one of the retaining profile pairs being provided with hook profiles is, namely on a panel edge with a receiving hook and on the opposite panel edge with a locking hook.

Mit derlei Paneelen werden beispielsweise Fußbodenbeläge hergestellt, insbesondere eignen sich solche Paneele für schwimmend verlegte Fußbodenbeläge. Die Paneele weisen üblicherweise dekorative Oberflächen auf.Flooring of this type is used to produce floor coverings, for example, such panels are particularly suitable for floating floor coverings. The panels usually have decorative surfaces.

Das vorzuschlagende Paneel soll sich eignen für eine Verriegelung nach der "fold-down-Methode". Für diese Methode wird eine Paneelart benutzt, bei der eines der Halteprofilpaare mit einem modifizierten Nut- und Federprofil versehen ist, während das andere Halteprofilpaar mit den erfindungsgemäßen Hakenprofilen versehen ist. Für die fold-down-Methode wird ein neues Paneel angewinkelt und vorzugsweise mit seiner Federprofilkante an die Nutprofilkante eines liegenden Paneels beziehungsweise einer Paneelreihe herangebracht. Anschließend wird das neue Paneel in die Ebene der montierten Paneele herabgeschwenkt und dadurch das Federprofil formschlüssig mit dem Nutprofil verriegelt. Während der erwähnten Herabschwenkbewegung wird gleichzeitig auch eine formschlüssige Verriegelung der Hakenprofile erzeugt, weil sich eines der Hakenprofile scherenartig auf das andere Hakenprofil zu bewegt und formschlüssig mit diesem verhakt. Dabei findet eine Verriegelung statt.The panel to be proposed should be suitable for locking according to the "fold-down method". For this method, a type of panel is used in which one of the pairs of retaining profiles is provided with a modified tongue and groove profile, while the other pair of retaining profiles is provided with the hook profiles according to the invention. For the fold-down method, a new panel is angled and preferably brought with its tongue profile edge to the groove profile edge of a lying panel or a row of panels. The new panel is then swiveled down into the level of the assembled panels, thereby locking the tongue profile with the groove profile. During the mentioned swiveling-down movement, a positive locking of the hook profiles is also generated at the same time, because one of the hook profiles scissors-like on the other hook profile too moved and positively hooked with this. There is a lock.

Die vorgeschlagenen Hakenprofile eignen sich darüber hinaus aber auch für eine push-down-Verriegelung. Für eine push-down-Verriegelung müssen alle Halteprofilpaare eines Paneels durch eine vertikale Bewegung verbunden werden können, d.h. beispielsweise durch eine absenkende Bewegung eines Paneels, nämlich in einer zur Paneeloberseite senkrechten Richtung (vertikal). Die fold-down-Methode ist dann nicht anwendbar.The proposed hook profiles are also suitable for push-down locking. For a push-down locking, all pairs of holding profiles of a panel must be able to be connected by a vertical movement, i.e. for example by a lowering movement of a panel, namely in a direction perpendicular to the top of the panel (vertical). The fold-down method is then not applicable.

In der Praxis kommt es vor, dass ein Paneel an dem Ende einer Paneelreihe nicht verriegelt werden kann, weil eine Wand im Weg und das Paneel zu lang ist. Damit die Lücke im Boden geschlossen werden kann, ist es üblich, ein Paneel z.B. mit einer Säge zu durchtrennen, um es auf die benötigte Länge zu kürzen. Mit dem abgetrennten Reststück des Paneels kann in der Regel eine neue Paneelreihe begonnen werden. Grundsätzlich passen die komplementären Halteprofile eines durchtrennten Paneels stets ineinander. Im Prinzip können daher komplementäre Halteprofilkanten eines durchtrennten Paneels miteinander verriegelt werden.In practice, it happens that a panel cannot be locked at the end of a row of panels because a wall is in the way and the panel is too long. So that the gap in the floor can be closed, it is common to use a panel e.g. cut with a saw to shorten it to the required length. A new row of panels can usually be started with the separated remnant of the panel. The complementary holding profiles of a severed panel always fit together. In principle, therefore, complementary retaining profile edges of a severed panel can be locked together.

Die WO 01/02670 schlägt verschiedene Hakenprofilpaare vor. Die Hakenprofile sollen ein horizontales Auseinanderziehen der Paneele, d.h. in der Paneelebene und senkrecht zu den verriegelten Paneelkanten verhindern. Es zeigt sich jedoch bei einer Belastung in der genannten horizontalen Richtung, dass die Festigkeit der Hakenprofile unbefriedigend ist.The WO 01/02670 suggests different hook profile pairs. The hook profiles are intended to prevent the panels from being pulled apart horizontally, ie in the plane of the panel and perpendicular to the locked panel edges. With a load in the horizontal direction mentioned, however, it is found that the strength of the hook profiles is unsatisfactory.

DE102011086846 beschreibt ein Paneel umfassend eine Oberseite, eine Unterseite, einen Rumpf, komplementäre Verriegelungsmittel, die paarweise an sich gegenüberliegenden Paneelkanten vorgesehen sind, wenigstens ein Paar Verriegelungsmittel mit Hakenprofilen, nämlich einem Aufnahmehaken, und diesem gegenüberliegend einem Arretierhaken, mit der Maßgabe, dass der ufnahmehaken rumpffern angeordnet einen Hakenrand und rumpfnäher angeordnet eine Aufnahmeaussparung aufweist, wobei die Aufnahmeaussparung zur Oberseite offen ist, dass der Arretierhaken mit einer rumpfnäher angeordneten und zur Unterseite offenen Arretieraussparung versehen ist und einen rumpffern angeordneten Arretierabsatz aufweist, der in senkrechter Fügerichtung in die Aufnahmeaussparung des Aufnahmehakens passt DE102011086846 describes a panel comprising an upper side, a lower side, a body, complementary locking means which are provided in pairs on opposite panel edges, at least one pair of locking means with hook profiles, namely a receiving hook, and opposite this a locking hook, with the proviso that the receiving hook is distant from the body arranged a hook edge and closer to the body arranged has a receiving recess, the receiving recess being open at the top, that the locking hook is provided with a locking recess arranged closer to the body and open to the underside, and has a locking shoulder arranged away from the body, which fits in the vertical joining direction into the receiving recess of the receiving hook

EP 1108529 beschreibt eine thermoplastische Laminatplanke, wobei die thermoplastische Laminatplanke einen Kern, eine Druckschicht und gegebenenfalls eine Auflage umfasst. Der Kern umfasst mindestens ein thermoplastisches Material und hat eine obere Oberfläche und eine untere Oberfläche, wobei eine Druckschicht an der oberen Oberfläche des Kerns angebracht ist und eine Überzugsschicht an der oberen Oberfläche der Druckschicht angebracht ist. Weitere Paneele mit Hakenprofilpaaren sind aus der WO 2010/ 143962 A1 bekannt. Die verschiedenen Ausführungsbeispiele dieses Standes der Technik kranken daran, dass die Hakenprofilpaare, wenn sie in der Paneelebene und senkrecht zu den verriegelten Paneelkanten auseinandergezogen werden, bersten können. Dies geschieht insbesondere dann, wenn die Paneele aus künstlichem Holzwerkstoff bestehen, die aus Holzpartikeln oder -fasern bestehen, die mit einem Bindemittel zu einem Plattenmaterial gebunden sind. EP 1108529 describes a thermoplastic laminate plank, the thermoplastic laminate plank comprising a core, a printing layer and optionally a support. The core comprises at least one thermoplastic material and has an upper surface and a lower surface, a printing layer being attached to the upper surface of the core and an overcoating layer being attached to the upper surface of the printing layer. Other panels with hook profile pairs are from the WO 2010/143962 A1 known. The various exemplary embodiments of this prior art suffer from the fact that the pairs of hook profiles can burst if they are pulled apart in the plane of the panel and perpendicular to the locked panel edges. This happens in particular when the panels are made of artificial wood material, which consist of wood particles or fibers, which are bound with a binder to form a plate material.

Daher sucht die Anmelderin nach einem Paneel mit einem verbesserten Hakenprofilpaar.The applicant is therefore looking for a panel with an improved pair of hook profiles.

Die Erfindung schlägt zu diesem Zweck vor, ein Paneel gemäß Anspruch 1.For this purpose, the invention proposes a panel according to claim 1.

Der Normalvektor ist im Sinne der Erfindung jeweils von der entsprechenden Verriegelungsfläche senkrecht nach außen gerichtet (nicht ins Paneelmaterial gerichtet). Der Normalvektor schließt mit der jeweiligen Paneelseite, die er schneidet, jeweils einen Winkel ein, welcher gleich groß ist, wie das Winkelmaß, um das die Verriegelungsflächen gegenüber dem Lot auf der Paneeloberseite geneigt sind (Wechselwinkel).In the sense of the invention, the normal vector is directed vertically outwards from the corresponding locking surface (not directed into the panel material). The normal vector encloses an angle with the respective panel side that it cuts, which is the same size as the angle by which the locking surfaces are inclined relative to the solder on the top side of the panel (alternating angle).

Die Neigung der Verriegelungsflächen gegenüber dem Lot auf der Paneeloberseite kann in einem Winkelbereich α von 4° bis 50° liegen. Bevorzugt liegt der Winkel α in einem Bereich von 5° bis 30°undbesonders bevorzugt in einem Bereich von 5° bis 15°.The inclination of the locking surfaces with respect to the solder on the top of the panel can be in an angular range α of 4 ° to 50 °. The angle α is preferably in a range from 5 ° to 30 ° and particularly preferably in a range from 5 ° to 15 °.

Gemäß der Erfindung besteht der Rumpf des Paneels zumindest teilweise aus Polyvinylchlorid (PVC), wobei ein Weichmacher vorgesehen ist, der in einem Bereich von ≥0 Gew.-% bis ≤20 Gew.-%, insbesondere ≤10 Gew.-%, vorzugsweise ≤7 Gew.-%, beispielsweise in einem Bereich von ≥5 Gew.-% bis ≤10 Gew.-% vorliegt. Ein geeigneter Weichmacher umfasst etwa den unter der Handelsbezeichnung "Dinsch" von der Firma BASF vertriebenen Weichmacher. Ferner können als Ersatz für herkömmliche Weichmacher Copolymere, wie etwa Acrylate oder Methacrylate, vorgesehen sein.According to the invention, the fuselage of the panel consists at least partially of polyvinyl chloride (PVC), a plasticizer being provided, in particular in a range from 00% by weight to ≤20% by weight ≤10% by weight, preferably ≤7% by weight, for example in a range from ≥5% by weight to ≤10% by weight. A suitable plasticizer includes, for example, the plasticizer marketed by BASF under the trade name "Dinsch". Copolymers, such as acrylates or methacrylates, can also be provided as a replacement for conventional plasticizers.

Insbesondere thermoplastische Kunststoffe bieten auch den Vorteil, dass die aus ihnen hergestellten Produkte sehr leicht rezykliert werden können. Es können auch Recycling-Materialien aus anderen Quellen verwendet werden. Hierdurch ergibt sich eine weitere Möglichkeit zur Senkung der Herstellungskosten.Thermoplastic materials in particular also have the advantage that the products made from them can be recycled very easily. Recycled materials from other sources can also be used. This provides another way of reducing manufacturing costs.

Derartige Trägerplatten sind dabei sehr elastisch beziehungsweise federnd, was einen komfortablen Eindruck beim Begehen erlaubt und ferner die auftretenden Geräusche bei einem Begehen im Vergleich zu herkömmlichen Materialien reduzieren kann, somit eine verbesserter Trittschalldämmung realisierbar sein kann.Support plates of this type are very elastic or resilient, which allows a comfortable impression when walking on them and furthermore can reduce the noises occurring when walking on compared to conventional materials, so that improved impact sound insulation can be realized.

Darüber hinaus bieten die vorgenannten Trägerplatten den Vorteil einer guten Wasserfestigkeit, da sie eine Quellung von 1% oder weniger aufweisen. Dies gilt in überraschender Weise neben reinen Kunststoffträgern auch für WPC-Werkstoffe, wie diese nachfolgend im Detail erläutert sind. In besonders vorteilhafter Weise kann das Material der Trägerplatte Holz-Polymer-Werkstoffe (Wood Plastic Composite, WPC) aufweisen oder daraus bestehen. Hier kann beispielhaft ein Holz und ein Polymer geeignet sein, welches in einem Verhältnis von 40/60 bis 70/30, beispielsweise 50/50 vorliegen kann. Als polymere Bestandteile können etwa Polypropylen, Polyethylen oder ein Copolymer aus den beiden vorgenannten Materialien verwendet werden. Derartige Materialien bieten den Vorteil, dass diese bereits bei geringen Temperaturen, wie etwa in einem Bereich von ≥180°C bis ≤200°C in dem vorbeschriebenen Verfahren zu einer Trägerplatte geformt werden können, so dass eine besonders effektive Prozessführung, etwa mit beispielhaften Liniengeschwindigkeiten in einem Bereich von 6m/min, ermöglicht werden kann. Beispielsweise sind für ein WPC-Produkt mit einer 50/50 Verteilung der Holz- und Polymeranteile bei einer beispielhaften Produktstärke von 4,1 mm möglich, was einen besonders effektiven Herstellungsprozess ermöglichen kann.In addition, the above-mentioned carrier plates offer the advantage of good water resistance, since they have a swelling of 1% or less. In a surprising way, this applies not only to pure plastic supports but also to WPC materials, as explained in detail below. In a particularly advantageous manner, the material of the carrier plate can comprise or consist of wood-polymer materials (Wood Plastic Composite, WPC). For example, a wood and a polymer can be suitable here, which can be in a ratio of 40/60 to 70/30, for example 50/50. Polypropylene, polyethylene or a copolymer of the two aforementioned materials can be used as polymer components. Such materials offer the advantage that they can be formed into a carrier plate at low temperatures, such as in a range from ≥180 ° C to ≤200 ° C in the above-described process, so that particularly effective process control, for example with line speeds in one Range of 6m / min. For example, for a WPC product with a 50/50 distribution of the wood and polymer parts with an exemplary product thickness of 4.1 mm, this is possible, which can enable a particularly effective manufacturing process.

Ferner können so sehr stabile Paneele erzeugt werden, die weiterhin eine hohe Elastizität aufweisen, was insbesondere für eine effektive und kostengünstige Ausgestaltung von Verbindungselementen an dem Randbereich der Trägerplatte und ferner bezüglich einer Trittschalldämmung von Vorteil sein kann. Ferner kann auch die vorgenannte gute Wasserverträglichkeit mit einer Quellung von unter 1% bei derartigen WPC-Materialien ermöglicht werden. Dabei können WPC-Werkstoffe beispielsweise Stabilisatoren und/oder andere Additive aufweisen, welche bevorzugt im Kunststoffanteil vorliegen können.Furthermore, very stable panels can be produced that still have a high elasticity, which can be particularly advantageous for an effective and inexpensive design of connecting elements on the edge area of the carrier plate and also with regard to impact sound insulation. Furthermore, the aforementioned good water compatibility with a swelling of less than 1% can be made possible with such WPC materials. WPC materials can have, for example, stabilizers and / or other additives, which can preferably be present in the plastic portion.

Weiterhin kann es besonders vorteilhaft sein, dass die Trägerplatte ein PVC-basiertes Material umfasst oder daraus besteht. Auch derartige Materialien können in besonders vorteilhafter Weise für hochwertige Paneele dienen, welche etwa auch in Feuchträumen problemlos verwendbar sind. Ferner bieten sich auch PVC-basierte Materialien für die Trägerplatte für einen besonders effektiven Herstellungsprozess an, da hier etwa Liniengeschwindigkeiten von 8m/min bei einer beispielhaften Produktstärke von 4,1 mm möglich sein können, was einen besonders effektiven Herstellungsprozess ermöglichen kann. Ferner weisen auch derartige Trägerplatten eine vorteilhafte Elastizität und Wasserverträglichkeit auf, was zu den vorgenannten Vorteilen führen kann.Furthermore, it can be particularly advantageous that the carrier plate comprises or consists of a PVC-based material. Such materials can also be used in a particularly advantageous manner for high-quality panels, which can also be used without problems in damp rooms, for example. Furthermore, PVC-based materials are also suitable for the carrier plate for a particularly effective manufacturing process, since line speeds of 8 m / min with an exemplary product thickness of 4.1 mm can be possible here, which can enable a particularly effective manufacturing process. Furthermore, such carrier plates also have advantageous elasticity and water compatibility, which can lead to the aforementioned advantages.

Bei Kunststoff-basierten Paneelen wie auch bei WPC-basierten Paneelen können dabei mineralische Füllstoffe von Vorteil sein. Gemäß der Erfindung ist in dem Rumpf Kalziumcarbonat in einem Bereich von ≥30 Gew.-% bis ≤70 Gew.-% vorgesehen, wobei durch die Kreide insbesondere der Schlupf der Trägerplatte verbessert werden kann. Auch können sie in bekannter Weise eingefärbt sein. Insbesondere kann es vorgesehen sein, dass das Material der Trägerplatten ein Flammschutzmittel aufweist.Mineral fillers can be an advantage for plastic-based panels as well as for WPC-based panels. According to the invention, calcium carbonate is provided in the fuselage in a range from 30 30% by weight to 70 70% by weight, the chalk of the carrier plate in particular being able to be improved by the chalk. They can also be colored in a known manner. In particular, it can be provided that the material of the carrier plates has a flame retardant.

Gemäß einer nicht beanspruchten Ausgestaltung besteht das Material der Trägerplatte aus einer Mischung eines PE/PP Blockcopolymers mit Holz. Dabei kann der Anteil des PE/PP Blockcopolymers sowie der Anteil des Holzes zwischen ≥45 Gew.-% und ≤55 Gew.-% liegen. Des Weiteren kann das Material der Trägerplatte zwischen ≥0 Gew.-% und ≤10 Gew.-% weiterer Additive, wie beispielsweise Fließhilfsmittel, Thermostabilisatoren oder UV-Stabilisatoren, aufweisen. Die Partikelgröße des Holzes liegt dabei zwischen >0 µm und ≤600 µm mit einer bevorzugten Partikelgrößenverteilung D50 von ≥400 µm. Insbesondere kann das Material der Trägerplatte dabei Holz mit einer Partikelgrößenverteilung D10 von ≥400 µm aufweisen. Die Partikelgrößenverteilung ist dabei auf den volumetrischen Durchmesser bezogen und bezieht sich auf das Volumen der Partikel. Besonders bevorzugt wird dabei das Material der Trägerplatte als granulierte oder pelletierte vorextrudierte Mischung aus einem PE/PP Blockcopolymer mit Holzpartikeln der angegeben Partikelgrößenverteilung bereitgestellt. Das Granulat und/oder die Pellets können dabei bevorzugt etwa eine Korngröße in einem Bereich von ≥400 µm bis ≤10 mm, bevorzugt ≥600 µm bis ≤10 mm aufweisen, insbesondere ≥800 µm bis ≤10 mm.According to an embodiment not claimed, the material of the carrier plate consists of a mixture of a PE / PP block copolymer with wood. The proportion of the PE / PP block copolymer and the proportion of wood can be between ≥45% by weight and ≤55% by weight. Furthermore, the material of the carrier plate can have between 00% by weight and ≤10% by weight of further additives, such as flow aids, thermal stabilizers or UV stabilizers. The particle size of the wood is between> 0 µm and ≤600 µm with a preferred particle size distribution D50 of ≥400 µm. In particular, the material of the carrier plate can have wood with a particle size distribution D10 of ≥400 µm.

It can also be used to determine D50 or D10 values which are 50% or 10% of the measured particles smaller than the specified value.

Gemäß einer weiteren nicht beanspruchten Ausgestaltung weist das Material der Trägerplatte ein einen Kunststoff aufweisendes Matrixmaterial und ein Feststoffmaterial auf, wobei das Feststoffmaterial zu wenigstens 50 Gew.-%, insbesondere zu wenigstens 80 Gew.-%, besonders bevorzugt zu wenigstens 95 Gew.-%, bezogen auf das Feststoffmaterial, durch Talkum gebildet ist. Dabei liegt das Matrixmaterial in einer Menge, bezogen auf das Material der Träger, von ≥ 30 Gew.-% bis ≤ 70 Gew.-%, insbesondere von ≥ 40 Gew.-% bis ≤ 60 Gew.-%, vor und liegt das Feststoffmaterial, bezogen auf das Material der Träger, in einer Menge, bezogen auf das Material der Trägerplatte, von ≥ 30 Gew.-% bis ≤ 70 Gew.-%, insbesondere von ≥ 40 Gew.-% bis ≤ 60 Gew.-%, beispielsweise kleiner oder gleich 50 Gew.-% vor. Weiterhin ist es vorgesehen, dass das Material der Trägerplatte und das Feststoffmaterial gemeinsam, bezogen auf das Material der Trägerplatte in einer Menge von ≥ 95 Gew.-%, insbesondere ≥ 99 Gew.-%, vorliegen.According to a further embodiment which is not claimed, the material of the carrier plate has a matrix material comprising a plastic and a solid material, the solid material at least 50% by weight, in particular at least 80% by weight, particularly preferably at least 95% by weight , based on the solid material, is formed by talc. The matrix material is present in an amount, based on the material of the carrier, of 30 30% by weight to 70 70% by weight, in particular ≥ 40% by weight to 60 60% by weight, and that is Solid material, based on the material of the carrier, in an amount, based on the material of the carrier plate, of ≥ 30% by weight to ≤ 70% by weight, in particular from ≥ 40% by weight to ≤ 60% by weight, for example less than or equal to 50% by weight. Furthermore, it is provided that the material of the carrier plate and the solid material are present together, based on the material of the carrier plate, in an amount of 95 95% by weight, in particular ≥ 99% by weight.

Das Feststoffmaterial kann in einer solchen Ausgestaltung zu wenigstens 50 Gew.-%, insbesondere zu wenigstens 80 Gew.-%, beispielsweise zu 100%, bezogen auf das Feststoffmaterial, durch Talkum gebildet sein. Unter Talkum wird dabei in an sich bekannter Weise ein Magnesiumsilikathydrat verstanden, welches beispielsweise die chemische Summenformel Mg3[Si4010(OH)2] aufweisen kann. Somit ist der Feststoffanteil vorteilhafter Weise zumindest durch einen Großteil aus dem mineralischen Stoff Talkum gebildet, wobei dieser Stoff etwa als Pulverform eingesetzt werden kann beziehungsweise in dem Material der Trägerplatte in Form von Partikeln vorliegen kann. Grundsätzlich kann das Feststoffmaterial aus einem pulverförmigen Feststoff bestehen. Vorteilhaft kann es sein, wenn die spezifische Oberflächendichte nach BET, ISO 4652 der Talkum-Partikel in einem Bereich liegt von ≥ 4 m2/g bis ≤ 8 m2/g, etwa in einem Bereich von ≥ 5 m2/g bis ≤ 7 m2/g.In such an embodiment, at least 50% by weight, in particular at least 80% by weight, for example 100%, based on the solid material, of the solid material can be formed by talc. Talc is understood to mean, in a manner known per se, a magnesium silicate hydrate which, for example, can have the chemical formula Mg3 [Si4010 (OH) 2]. The solid fraction is thus advantageously formed at least by a large part from the mineral substance talc, this substance being able to be used, for example, in powder form or being present in the material of the carrier plate in the form of particles. In principle, the solid material can consist of a powdery solid. It may be advantageous if the specific surface density according to BET, ISO 4652 of the talc particles is in a range from ≥ 4 m2 / g to ≤ 8 m2 / g, for example in a range from ≥ 5 m2 / g to ≤ 7 m2 / G.

Weiterhin kann es vorteilhaft sein, wenn das Talkum bei einer Schüttdichte nach DIN 53468 vorliegt in einem Bereich von ≥ 0,15 g/cm3 bis ≤ 0,45 g/cm3, etwa in einem Bereich von ≥ 0,25 g/cm3 bis ≤ 0,35 g/cm3.It may also be advantageous if the talc is present at a bulk density in accordance with DIN 53468 in a range from 0,1 0.15 g / cm3 to 0,4 0.45 g / cm3, for example in a range from 0,2 0.25 g / cm3 to. 0.35 g / cm3.

Das Matrixmaterial in einer solchen Ausgestaltung dient insbesondere dazu, bei dem fertig hergestellten Träger das Feststoffmaterial aufzunehmen beziehungsweise einzubetten. Das Matrixmaterial weist dabei einen Kunststoff oder eine Kunststoffmischung auf. Insbesondere mit Bezug auf ein Herstellungsverfahren, kann es vorteilhaft sein, dass das Matrixmaterial einen thermoplastischen Kunststoff aufweist. Dadurch wird es ermöglicht, dass das Material der Trägerplatte beziehungsweise ein Bestandteil des Material der Trägerplattes einen Schmelzpunkt oder einen Erweichungspunkt aufweist, um das Material der Trägerplatte in einem weiteren Verfahrensschritt durch Hitzeeinwirkung zu formen. Das Matrixmaterial kann insbesondere aus einem Kunststoff beziehungsweise einem Kunststoffgemisch und gegebenenfalls einem Haftvermittler bestehen. Bevorzugt können diese Komponenten zumindest 90Gew.-%, besonders bevorzugt zumindest 95 Gew.-%, insbesondere wenigstens 99 Gew.-% des Matrixmaterials ausmachen.The matrix material in such a configuration serves in particular to absorb or embed the solid material in the finished carrier. The matrix material has a plastic or a plastic mixture. In particular with reference to a manufacturing process, it can be advantageous that the matrix material has a thermoplastic plastic. This makes it possible for the material of the carrier plate or a component of the material of the carrier plate to have a melting point or a softening point in order to form the material of the carrier plate in a further process step by the action of heat. The matrix material can in particular consist of a plastic or a plastic mixture and optionally an adhesion promoter. These components can preferably make up at least 90% by weight, particularly preferably at least 95% by weight, in particular at least 99% by weight of the matrix material.

Ferner kann es vorgesehen sein, dass das Matrixmaterial in einer Menge, bezogen auf das Material der Trägerplatte, von ≥ 30 Gew.-% bis ≤ 70 Gew.-%, insbesondere von ≥ 40 Gew.-% bis ≤ 60 Gew.-% vorliegt. Weiterhin ist es vorgesehen, dass das Feststoffmaterial, bezogen auf das Material der Trägerplatte, in einer Menge, bezogen auf das Material der Trägerplatte, von ≥ 30 Gew.-% bis ≤ 70 Gew.-%, insbesondere von ≥ 40 Gew.-% bis ≤ 60 Gew.-%, vorliegt.Furthermore, it can be provided that the matrix material in an amount, based on the material of the carrier plate, of ≥ 30% by weight to ≤ 70% by weight, in particular from ≥ 40% by weight to ≤ 60% by weight is present. Furthermore, it is provided that the solid material, based on the material of the carrier plate, in an amount, based on the material of the carrier plate, of ≥ 30% by weight to ≤ 70% by weight, in particular of ≥ 40% by weight up to ≤ 60% by weight.

Polypropylen ist als Matrixmaterial besonders geeignet, da es zum einen kostengünstig erhältlich ist und ferner als thermoplastischer Kunststoff gute Eigenschaften als Matrixmaterial zum Einbetten des Feststoffmaterials aufweist. Dabei kann insbesondere eine Mischung aus einem Homopolymer und einem Copolymer für das Matrixmaterial besonders vorteilhafte Eigenschaften ermöglichen. Derartige Materialien bieten ferner den Vorteil, dass diese bereits bei geringen Temperaturen, wie etwa in einem Bereich von ≥ 180°C bis ≤ 200°C in dem vorbeschriebenen Verfahren zu einem Träger geformt werden können, so dass eine besonders effektive Prozessführung, etwa mit beispielhaften Liniengeschwindigkeiten in einem Bereich von 6m/min, ermöglicht werden kann.Polypropylene is particularly suitable as a matrix material because, on the one hand, it is available inexpensively and, as a thermoplastic, it also has good properties as a matrix material for embedding the solid material. In particular, a mixture of a homopolymer and a copolymer can enable particularly advantageous properties for the matrix material. Such materials also offer the advantage that they can be formed into a carrier at low temperatures, for example in a range from 180 180 ° C. to 200 200 ° C., in the method described above, so that particularly effective process management, for example with Line speeds in a range of 6m / min can be made possible.

Weiterhin kann es vorteilhaft sein, wenn das Homopolymer eine Zugfestigkeit nach ISO 527-2 aufweist, die in einem Bereich liegt von ≥30 MPa bis ≤ 45 MPa, beispielsweise in einem Bereich von ≥35 MPa bis ≤ 40 MPa, um eine gute Stabilität zu erreichen.Furthermore, it can be advantageous if the homopolymer has a tensile strength according to ISO 527-2, which is in a range from 30 30 MPa to 45 45 MPa, for example in a range from 35 35 MPa to 40 40 MPa, in order to ensure good stability to reach.

Ferner kann insbesondere für eine gute Stabilität es von Vorteil sein, wenn das Homopolymer ein Biegemodul nach ISO 178 aufweist in einem Bereich von ≥ 1000 MPa bis ≤ 2200 MPa, beispielsweise in einem Bereich von ≥ 1300 MPa bis ≤ 1900 MPa, etwa in einem Bereich von ≥ 1500 MPa bis ≤ 1700 MPa.Furthermore, it may be advantageous in particular for good stability if the homopolymer has a flexural modulus according to ISO 178 in a range from 1000 1000 MPa to 22 2200 MPa, for example in a range from 13 1300 MPa to 1900 1900 MPa, for example in a range from ≥ 1500 MPa to ≤ 1700 MPa.

Bezüglich der Zugverformung des Homopolymers nach ISO 527-2 kann es ferner von Vorteil sein, wenn diese in einem Bereich liegt von ≥ 5% bis ≤ 13%, beispielsweise in einem Bereich von ≥ 8% MPa bis ≤ 10%.With regard to the tensile deformation of the homopolymer according to ISO 527-2, it can also be advantageous if this is in a range from 5 5% to 13 13%, for example in a range from 8 8% MPa to 10 10%.

Für eine besonders vorteilhafte Herstellbarkeit kann es vorgesehen sein, dass die Vicat-Erweichungstemperatur nach ISO 306/A für ein spritzgegossenes Bauteil, in einem Bereich liegt von ≥ 130°C MPa bis ≤ 170°C, beispielsweise in einem Bereich von ≥ 145°C bis ≤ 158°C.For a particularly advantageous producibility, it can be provided that the Vicat softening temperature according to ISO 306 / A for an injection molded component is in a range from ≥ 130 ° C MPa to ≤ 170 ° C, for example in a range from ≥ 145 ° C up to ≤ 158 ° C.

Es kann weiterhin vorteilhaft sein, dass das Feststoffmaterial neben Talkum wenigstens einen weiteren Feststoff aufweist. Diese Ausgestaltung kann es insbesondere ermöglichen, dass das Gewicht des Materials der Trägerplattes beziehungsweise eines mit dem Material der Trägerplatte ausgebildeten Paneels verglichen mit einem Material der Trägerplatte beziehungsweise Paneel, bei dem das Feststoffmaterial aus Talkum besteht, deutlich reduziert sein kann. Somit kann der dem Feststoffmaterial zugesetzte Feststoff insbesondere eine verglichen mit Talkum reduzierte Dichte aufweisen. Beispielsweise kann der zugesetzte Stoff eine Rohdichte aufweisen, die in einem Bereich liegt von ≤ 2000 kg/m3, insbesondere von ≤ 1500 kg/m3, beispielsweise von ≤ 1000 kg/m3, besondere bevorzugt von ≤ 500 kg/m3. In Abhängigkeit des zugesetzten Feststoffs kann dabei ferner eine weitere Adaptierbarkeit an die gewünschten insbesondere mechanischen Eigenschaften ermöglicht werden.It can furthermore be advantageous for the solid material to have at least one further solid in addition to talc. This configuration can in particular make it possible for the weight of the material of the carrier plate or of a panel formed with the material of the carrier plate to be significantly reduced compared to a material of the carrier plate or panel in which the solid material consists of talc. Thus, the solid added to the solid material can in particular have a reduced density compared to talc. For example, the added substance can have a bulk density that is in a range of 2000 2000 kg / m3, in particular of 1500 1500 kg / m3, for example of 1000 1000 kg / m3, particularly preferably of 500 500 kg / m3. Depending on the added Solid can further be adapted to the desired mechanical properties in particular.

Beispielhaft kann der weitere Feststoff ausgewählt sein aus der Gruppe bestehend aus Holz, etwa in Form von Holzmehl, Blähton, Vulkanasche, Bims, Porenbeton, insbesondere anorganischen Schäumen, Cellulose. Mit Bezug auf Porenbeton kann dies beispielsweise der von der Firma Xella unter dem Markennamen YTONG verwendete Feststoff sein, der im Wesentlichen aus Quarzsand, Kalk und Zement besteht, beziehungsweise kann der Porenbeton die vorgenannten Bestandteile aufweisen. Mit Bezug auf den zugesetzten Feststoff kann dieser Beispielsweise aus Partikeln aufgebaut sein, die die gleiche Partikelgröße beziehungsweise Partikelgrößenverteilung aufweisen, wie die vorstehend für Talkum vorbeschriebenen Partikelgrößen beziehungsweise Partikelgrößenverteilungen. Die weiteren Feststoffe können insbesondere in einem Anteil in dem Feststoffmaterial vorliegen, der in einem Bereich von < 50 Gew.-%, insbesondere < 20 Gew.-%, beispielsweise < 10 Gew.-%, weiter beispielsweise < 5 Gew.-%, liegt.By way of example, the further solid can be selected from the group consisting of wood, for example in the form of wood flour, expanded clay, volcanic ash, pumice, aerated concrete, in particular inorganic foams, cellulose. With regard to aerated concrete, this can be, for example, the solid used by the Xella company under the brand name YTONG, which essentially consists of quartz sand, lime and cement, or the aerated concrete can have the aforementioned components. With respect to the added solid, this can be built up, for example, from particles which have the same particle size or particle size distribution as the particle sizes or particle size distributions described above for talc. The further solids can in particular be present in the solid material in a proportion which is in a range from <50% by weight, in particular <20% by weight, for example <10% by weight, furthermore for example <5% by weight, lies.

Alternativ kann es beispielsweise für Holz, insbesondere für Holzmehl vorgesehen sein, dass dessen Partikelgröße zwischen >0µm und ≤600µm mit einer bevorzugten Partikelgrößenverteilung D50 von ≥400µm liegt.Alternatively, it can be provided, for example for wood, in particular for wood flour, that its particle size is between> 0 μm and 600 600 μm with a preferred particle size distribution D50 of 400 400 μm.

Gemäß einer weiteren nicht beanspruchten Ausgestaltung kann das Material der Trägerplatte Mikrohohlkugeln aufweisen. Derartige Zusatzstoffe können insbesondere bewirken, dass die Dichte der Trägerplatte und damit des erzeugten Paneels signifikant reduziert werden kann, so dass ein besonders einfacher und kostengünstiger Transport und ferner ein besonders komfortables Verlegen gewährleistet werden kann. Dabei kann insbesondere durch das Einfügen von Mikrohohlkugeln eine Stabilität des erzeugten Paneels gewährleistet werden, welche im Vergleich zu einem Material ohne Mikrohohlkugeln nicht signifikant reduziert ist. Somit ist die Stabilität für einen Großteil der Anwendungen vollkommen ausreichend. Unter Mikrohohlkugeln können dabei insbesondere Gebilde verstanden werden, welche einen hohlen Grundkörper aufweisen und eine Größe beziehungsweise einen maximalen Durchmesser aufweisen, der im Mikrometerbereich liegt. Beispielsweise können verwendbare Hohlkugeln einen Durchmesser aufweisen, welcher im Bereich von ≥5 µm bis ≤100 µm, beispielsweise ≥20 µm bis ≤50 µm liegt. Als Material der Mikrohohlkugeln kommt grundsätzlich jegliches Material in Betracht, wie beispielsweise Glas oder Keramik. Ferner können aufgrund des Gewichts Kunststoffe, etwa die auch in dem Material der Trägerplatte verwendeten Kunststoffe, beispielsweise PVC, PE oder PP, vorteilhaft sein, wobei diese gegebenenfalls, etwa durch geeignete Zusatzstoffe, an einem Verformen während des Herstellungsverfahrens gehindert werden können.According to a further embodiment which is not claimed, the material of the carrier plate can have hollow microspheres. Additives of this type can in particular have the effect that the density of the carrier plate and thus of the panel produced can be significantly reduced, so that particularly simple and inexpensive transport and also particularly convenient laying can be ensured. In this case, in particular by inserting hollow microspheres, a stability of the panel produced can be ensured, which is not significant in comparison with a material without hollow microspheres is reduced. The stability is therefore completely sufficient for a large number of applications. Hollow microspheres can in particular be understood to mean structures which have a hollow base body and have a size or a maximum diameter which is in the micrometer range. For example, hollow spheres that can be used can have a diameter which is in the range from 5 5 μm to 100 100 μm, for example 20 20 μm to 50 50 μm. In principle, any material, such as glass or ceramic, can be considered as the material of the hollow microspheres. Furthermore, plastics, for example the plastics also used in the material of the carrier plate, for example PVC, PE or PP, can be advantageous on account of the weight, it being possible, where appropriate, for example by suitable additives, to prevent them from being deformed during the production process.

Die Härte des Materials der Trägerplatte kann Werte in einem Bereich von 30-90 N/mm2 (gemessen nach Brinell) aufweisen. Der E-Modul kann in einem Bereich von 3.000 bis 7.000 N/mm2 liegen.
Das Teilstück des Nutgrunds der Arretiernut und das Teilstück der Oberseite des Aufnahmerands können im verriegelten Zustand parallel zueinander ausgerichtet sein.The hardness of the material of the carrier plate can have values in a range of 30-90 N / mm 2 (measured according to Brinell). The modulus of elasticity can be in a range from 3,000 to 7,000 N / mm 2 .
The section of the groove base of the locking groove and the section of the top of the receiving edge can be aligned parallel to one another in the locked state.

Die Aufnahmenut des einen Hakenprofils ist so beschaffen, dass der Arretierrand des komplementären Hakenprofils in die Aufnahmenut hineinpasst und die Arretiernut des komplementären Hakenprofils ist so beschaffen, dass der Aufnahmerand des einen Hakenprofils in die Arretiernut hineinpasst.The receiving groove of the one hook profile is such that the locking edge of the complementary hook profile fits into the receiving groove and the locking groove of the complementary hook profile is such that the receiving edge of the one hook profile fits into the locking groove.

Eine Weiterbildung sieht vor, dass das erste Rastmittel der unteren Verrastung einen Rastvorsprung aufweist, und dass zweite Rastmittel der unteren Verrastung eine dazu passende Rastvertiefung aufweist.A further development provides that the first latching means of the lower latching has a latching projection and that the second latching means of the lower latching has a matching latching recess.

Alternativ kann das erste Rastmittel der unteren Verrastung eine Rastvertiefung und dass zweite Rastmittel der unteren Verrastung einen dazu passenden Rastvorsprung aufweisen.Alternatively, the first locking means of the lower locking a locking recess and that second locking means of the lower locking have a matching locking projection.

Nützlich kann es außerdem sein, wenn eine obere Verrastung vorgesehen ist, die an einer Außenseite des Arretierrands ein erstes Rastmittel aufweist, und an einer zurückversetzten Nutflanke der Aufnahmenut ein dazu korrespondierendes zweites Rastmittel vorgesehen ist.It can also be useful if an upper latching is provided, which has a first latching means on an outside of the locking edge, and a corresponding second latching means is provided on a recessed groove flank of the receiving groove.

Zweckmäßig weist das erste Rastmittel der oberen Verrastung einen Rastvorsprung und dass zweite Rastmittel der oberen Verrastung eine dazu passende Rastvertiefung auf.The first latching means of the upper latching expediently has a latching projection and that second latching means of the upper latching has a matching latching recess.

Alternativ kann das erste Rastmittel der oberen Verrastung eine Rastvertiefung und dass zweite Rastmittel der oberen Verrastung einen dazu passenden Rastvorsprung aufweisen.Alternatively, the first latching means of the upper latching can have a latching recess and that the second latching means of the upper latching can have a suitable latching projection.

Ein weiterer Nutzen ergibt sich, wenn wenigstens ein Freiraum zwischen der Unterseite des Arretierrands und dem Nutgrund der Aufnahmenut vorgesehen ist. Der Freiraum kann Schmutzpartikel oder andere lose Partikel aufnehmen. Bei Paneelen aus Holzwerkstoffen können sich beispielsweise Partikel von der Paneelkante ablösen, die sich nicht zwischen Fügeflächen der Hakenprofile festsetzen sollen. Sie könnten andernfalls eine positionsrichtige Verriegelung der Hakenprofile behindern.A further benefit is obtained if at least one free space is provided between the underside of the locking edge and the groove base of the receiving groove. The free space can accommodate dirt particles or other loose particles. In the case of panels made of wood-based materials, for example, particles can detach from the panel edge and should not get stuck between the joining surfaces of the hook profiles. Otherwise you could hinder the correct locking of the hook profiles.

Darüber hinaus ist es nützlich, wenn im verriegelten Zustand eine Lücke zwischen Außenseite des Aufnahmerands und Nutflanke der Arretiernut vorgesehen ist.In addition, it is useful if, in the locked state, there is a gap between the outside of the receiving edge and the groove flank of the locking groove.

Günstigerweise berührt eine Unterseite des Arretierrands im verriegelten Zustand zumindest bereichsweise den Nutgrund der Aufnahmenut. Wenn im Bereich des Arretierrands eine Last auf die Paneeloberseite drückt, kann der Arretierrand diese Last tragen, weil seine Unterseite auf dem Nutgrund der Aufnahmenut des Aufnahmehakens abgestützt ist.Conveniently, an underside of the locking edge in the locked state touches the groove base of the receiving groove at least in regions. If a load presses on the top of the panel in the area of the locking edge, the locking edge can bear this load because its underside is supported on the groove base of the receiving groove of the receiving hook.

Der Aufnahmerand weist zweckmäßig einen Übergang zur Innenseite der Aufnahmenut auf, wobei der Übergang mit einer Krümmung versehen ist. Die Krümmung bietet einen Kantenschutz. Sie kann außerdem dazu dienen, den Arretierrand zu führen, wenn dieser mit der Krümmung in Berührung kommt. So wird der Arretierrand entlang der Krümmung hinabbewegt in die Aufnahmenut.The receiving edge expediently has a transition to the inside the receiving groove, the transition being provided with a curvature. The curvature provides edge protection. It can also be used to guide the locking edge when it comes into contact with the curvature. The locking edge is moved down the curvature into the receiving groove.

Fig. 1 zeigt eine perspektivische fold-down-Methode zur Verriegelung von Paneelen gemäß dem Stand der Technik. Dabei wird ein neues Paneel 1 schräg angewinkelt mit einer Federprofilkante 2 voran an eine Nutprofilkante 3 eines liegenden Paneels 4 einer vorherigen Paneelreihe herangebracht. Anschließend wird das neue Paneel 1 in die Ebene der montierten Paneele herabgeschwenkt, wobei in derselben Paneelreihe bereits ein identisches Paneel 5 liegt. Durch die schwenkende Fügebewegung verriegeln Nut- und Federprofilkante miteinander. Das neue Paneel 1 hat außerdem ein Paar Hakenprofile, nämlich einen Aufnahmehaken (nicht dargestellt) sowie einen Arretierhaken 6. Während der herabschwenkenden Fügebewegung wird der Arretierhaken 6 des neuen Paneels 1 scherenartig in Richtung des komplementären Aufnahmehakens 7 des identischen Paneels 5 zu bewegt. Dabei verhakt der Arretierhaken 6 mit dem Aufnahmehaken 7 und gleichzeitig mit der Verriegelung von Nut- und Federprofilkante geht eine formschlüssige Verriegelung der Hakenprofile vonstatten. Fig. 1 shows a perspective fold-down method for locking panels according to the prior art. A new panel 1 is angled at an angle with a tongue profile edge 2 leading to a slot profile edge 3 of a lying panel 4 of a previous row of panels. The new panel 1 is then pivoted down into the plane of the assembled panels, an identical panel 5 already lying in the same row of panels. The swiveling joining movement locks the tongue and groove profile edges together. The new panel 1 also has a pair of hook profiles, namely a receiving hook (not shown) and a locking hook 6. During the swiveling joining movement, the locking hook 6 of the new panel 1 is scissor-like in the direction of the complementary receiving hook 7 of the identical panel 5. The locking hook 6 hooks with the receiving hook 7 and at the same time with the locking of the tongue and groove profile edge, a positive locking of the hook profiles takes place.

Gemäß Fig. 1 ist der Aufbau einer Fußbodenfläche angedeutet. Bei diesem Beispiel wird ein neues Paneel stets fortlaufend nach links angelegt.According to Fig. 1 the construction of a floor surface is indicated. In this example, a new panel is always created to the left.

Fig. 2 zeigt ein zweites Beispiel für eine im Stand der Technik bekannte fold-down-Methode zur Verriegelung von Paneelen. Sie unterscheidet sich von der Methode der Fig. 1 nur dadurch, dass ein neues Paneel fortlaufend nach rechts angelegt werden muss, d.h. die Paneelkanten, die den Aufnahmehaken beziehungsweise den Arretierhaken aufweisen, sind gegenüber dem Beispiel von Fig. 1 vertauscht worden. Fig. 2 shows a second example of one in the prior art Technology known fold-down method for locking panels. It differs from the method of Fig. 1 only because a new panel has to be continuously laid to the right, ie the panel edges that have the receiving hook or the locking hook are compared to the example of Fig. 1 been exchanged.

Nut- und Federprofile, die sich für eine formschlüssige Verriegeln mittels der fold-down-Methode eignen, sind im Stand der Technik hinlänglich bekannt, zum Beispiel aus der WO 97/ 47834 A1 oder aus WO 00/63510 .Tongue and groove profiles that are suitable for positive locking using the fold-down method are well known in the prior art, for example from WO 97/47834 A1 or off WO 00/63510 .

Fig. 3 stellt ein erstes Ausführungsbeispiel eines erfindungsgemäßen Paneels 1 mit einer Paneeloberseite 1a und einer Paneelunterseite 1b dar, wobei vereinfacht nur ein Halteprofilpaar des Paneels dargestellt ist. Das hier gezeigte Halteprofilpaar weist komplementäre Hakenprofile auf, nämlich einen Arretierhaken 6 (oben) und einen Aufnahmehaken 7 (unten). Um die Funktionsweise zu erläutern kann man sich das Paneel 1 in zwei Teile durchtrennt vorstellten, so dass die beiden Hakenprofile (6 und 7) des Paneels miteinander verhakt werden können. Hakenprofile identischer Paneele werden selbstverständlich auf die gleiche Weise verriegelt. Fig. 3 represents a first embodiment of a panel 1 according to the invention with a panel top 1a and a panel underside 1b, with only one pair of retaining profiles of the panel being shown in simplified form. The pair of holding profiles shown here has complementary hook profiles, namely a locking hook 6 (above) and a receiving hook 7 (below). In order to explain the mode of operation, the panel 1 can be thought of as being cut into two parts so that the two hook profiles (6 and 7) of the panel can be hooked together. Hook profiles of identical panels are of course locked in the same way.

Der Aufnahmehaken 6 hat einen zur Paneeloberseite 1a gerichteten Aufnahmerand 8 und eine zur Paneeloberseite offene Aufnahmenut 9. Der Arretierhaken 7 ist mit einem zur Paneelunterseite 1b gerichteten Arretierrand 10 und mit einer zur Paneelunterseite 1b offenen Arretiernut 11 versehen.The receiving hook 6 has a receiving edge 8 directed towards the top of the panel 1a and a receiving groove 9 open towards the top of the panel. The locking hook 7 is provided with a locking edge 10 directed towards the underside of the panel 1b and with a locking groove 11 open towards the underside of the panel 1b.

Eine Innenseite des Aufnahmerands 8 ist der Aufnahmenut 9 zugewandt und diese Innenseite dient als untere Verriegelungsfläche 12. Dazu passend bildet der Arretierhaken 7 an einer der Arretiernut 11 zugewandten Innenseite seines Arretierrands 10 eine obere Verriegelungsfläche 13, welche mit der unteren Verriegelungsfläche 12 des Aufnahmerands 8 zusammenwirkt.An inside of the receiving edge 8 faces the receiving groove 9 and this inside serves as a lower locking surface 12. To this end, the locking hook 7 forms an upper locking surface 13 on an inside of its locking edge 10 facing the locking groove 11, which cooperates with the lower locking surface 12 of the receiving edge 8 .

Es ist sowohl die untere Verriegelungsfläche 12 als auch die obere Verriegelungsfläche 13 jeweils gegenüber dem Lot L auf der Paneeloberseite um einen Winkel α geneigt. Die Neigungen sind aneinander angeglichen, so dass die korrespondierenden Verriegelungsflächen 12 und 13 im verriegelten Zustand parallel zueinander ausgerichtet sind und sich berühren können.Both the lower locking surface 12 and the upper locking surface 13 are each inclined by an angle α with respect to the solder L on the upper side of the panel. The inclinations are aligned with one another, so that the corresponding locking surfaces 12 and 13 are aligned parallel to one another in the locked state and can touch.

Hinzu kommt, dass die Neigung der unteren Verriegelungsfläche 12 so gewählt ist, dass der Normalvektor N12, der von der unteren Verriegelungsfläche 12 senkrecht nach außen gerichtet ist, die Paneeloberseite 1a schneidet. Entsprechend umgekehrt ist der Normalvektor N13 auf der oberen Verriegelungsfläche 13 senkrecht nach außen gerichtet, so dass dieser Normalvektor N13 die gegenüberliegende Paneelunterseite 1b schneidet. Allgemein gilt, dass die Paneeloberseite 1a und der Normalvektor N12 einen Winkel einschließen, der ebenso groß ist, wie der oben erwähnte Winkel α (Wechselwinkel). Das gleiche gilt für die Paneelunterseite, die mit dem Normalvektor N13 einen gleich großen Winkel (Wechselwinkel) einschließt.In addition, the inclination of the lower locking surface 12 is selected such that the normal vector N 12 , which is directed vertically outwards from the lower locking surface 12, intersects the top side 1 a of the panel. Conversely, the normal vector N 13 on the upper locking surface 13 is directed vertically outwards, so that this normal vector N 13 intersects the opposite underside of the panel 1b. In general, the top of the panel 1a and the normal vector N 12 enclose an angle that is as large as the above-mentioned angle α (change angle). The same applies to the underside of the panel, which includes an equally large angle (change angle) with the normal vector N 13 .

Mit einer Unterseite 10a des Arretierrands 10 sitzt der Arretierhaken 7 fest auf einem Nutgrund 9a der Aufnahmenut 9 des Aufnahmehakens 6. Wenn im Bereich des Arretierrands 10 eine Last auf die Paneeloberseite 1a drückt, kann der Arretierrand 10 diese Last tragen, weil seine Unterseite 10a auf dem Nutgrund 9a der Aufnahmenut 9 abgestützt ist.With an underside 10a of the locking edge 10, the locking hook 7 is seated firmly on a groove base 9a of the receiving groove 9 of the receiving hook 6. If a load presses on the top side 1a of the panel in the area of the locking edge 10, the locking edge 10 can bear this load because its underside 10a the groove base 9a of the receiving groove 9 is supported.

Eine weitere Funktion der Hakenprofile ist jene, einem Höhenversatz der verriegelten Paneelkanten entgegenzuwirken. Zu diesem Zweck ist eine untere Verrastung 14 vorgesehen. Diese umfasst am Aufnahmehaken 7 ein erstes Rastmittel in Form eines hervorstehenden Rastvorsprungs 15. Der Rastvorsprung 15 ist an einer Außenseite 8a des Aufnahmerands 8 angeordnet. Dazu korrespondierend ist am Arretierhaken 7 ein zweites Rastmittel in Form einer Rastvertiefung 16 vorgesehen. Die Rastvertiefung 16 ist an einer zurückversetzten Nutflanke 11a der Arretiernut 11 angeordnet.Another function of the hook profiles is to counteract a height offset of the locked panel edges. For this purpose, a lower catch 14 is provided. This includes a first latching means in the form of a protruding latching projection 15 on the receiving hook 7. The latching projection 15 is arranged on an outer side 8a of the receiving edge 8. Corresponding to this, a second locking means in the form of a locking recess 16 is provided on the locking hook 7. The locking recess 16 is arranged on a recessed groove flank 11a of the locking groove 11.

Am Aufnahmehaken 6 hat ein Teilstück 8b der Oberseite des Aufnahmerands 8 eine Neigung abwärts, nämlich in Richtung der Außenseite 8a des Aufnahmerands fallend. Dazu passend ist am Arretierhaken 7 ein Teilstück 11b des Nutgrunds der Arretiernut 11 in komplementärer Weise angepasst an die Neigung des Teilstücks 8b der Oberseite des Aufnahmerands 8. Im verriegelten Zustand sind die geneigten Teilstücke 8b und 11b von Aufnahmerandoberseite und von Arretiernutgrund zueinander parallel ausgerichtet.On the receiving hook 6, a section 8b of the upper side of the receiving edge 8 has a downward slope, namely falling in the direction of the outside 8a of the receiving edge. A section 11b of the groove base of the locking groove 11 is matched to the locking hook 7 in a complementary manner to the inclination of the section 8b of the upper side of the receiving edge 8. In the locked state, the inclined sections 8b and 11b are aligned parallel to one another from the upper side of the receiving edge and from the locking groove base.

Außerdem ist am Aufnahmehaken 6 ein Übergang von der Oberseite 8b des Aufnahmerands 8 zur unteren Verriegelungsfläche 12 vorgesehen. Der Übergang ist als Krümmung 17 ausgebildet. Die Krümmung 17 ist im vorliegenden Beispiel ein Radius. Ebenfalls ist am Arretierhaken 7 ein Übergang mit einer Krümmung 18 zwischen dem Teilstück 11b des Nutgrunds der Arretiernut 11 und der oberen Verriegelungsfläche 13 vorgesehen. Die Krümmung 17 am Aufnahmerand bietet einen Kantenschutz sowie eine Führungsfläche. Der Kantenschutz ist stärker als die schützende Wirkung eine Phase welche die gleichen Breite und Höhe aufweist, wie die Krümmung 17. Die Krümmung 18 bildet eine Kehle. Sie hat im vorliegenden Beispiel einen Radius und dient der Stabilität im Übergangsbereich von der oberen Verriegelungsfläche 13 zum Nutgrund der Arretiernut 11.In addition, a transition from the upper side 8b of the receiving edge 8 to the lower locking surface 12 is provided on the receiving hook 6. The transition is designed as a curve 17. The curvature 17 is a radius in the present example. Also provided on the locking hook 7 is a transition with a curvature 18 between the section 11b of the groove base of the locking groove 11 and the upper locking surface 13. The curvature 17 at the receiving edge offers edge protection and a guide surface. The edge protection is stronger than the protective effect of a phase which has the same width and height as the curvature 17. The curvature 18 forms a throat. In the present example, it has a radius and serves for stability in the transition region from the upper locking surface 13 to the groove base of the locking groove 11.

Gemäß Fig. 4 sind die Hakenprofile aus Fig. 3 im verriegelten Zustand gezeigt. Der Rastvorsprung 15 des Aufnahmehakens 6, der an der Außenseite 8a des Aufnahmerands 8 angeordnet ist, greift formschlüssig in die Rastvertiefung 16, die an der zurückversetzten Nutflanke 11a der Arretiernut 11 angeordnet ist. Die untere Verrastung 14 wirkt einem Höhenversatz der beiden Paneeloberseiten 1a entgegen, d.h. einem Auseinanderbewegen der Paneelkanten senkrecht zur Paneeloberfläche wird entgegengewirkt. An der Paneeloberfläche 1a bildet sich auch in horizontaler Richtung eine geschlossene Fuge F. An dieser Fuge ist eine Außenseite 10b des Arretierrands 10 in Berührung mit einer zurückversetzten Nutflanke 9b der Aufnahmenut 9.According to Fig. 4 are the hook profiles Fig. 3 shown in the locked state. The locking projection 15 of the receiving hook 6, which is arranged on the outside 8a of the receiving edge 8, engages positively in the locking recess 16 which is arranged on the recessed groove flank 11a of the locking groove 11. The lower catch 14 counteracts a height offset of the two top surfaces 1a of the panel, ie a moving apart of the panel edges perpendicular to the panel surface is counteracted. A closed joint F is also formed on the panel surface 1a in the horizontal direction. At this joint, an outer side 10b of the locking edge 10 is in contact with a recessed groove flank 9b of the receiving groove 9.

Zwischen dem geneigtem Teilstück 11b des Nutgrund der Arretiernut und dem geneigten Teilstück 8b der Oberseite des Aufnahmerands 8 ist ein Spalt 19 vorhanden. Dieser begünstigt es, an der Fuge F der Paneeloberseite 1a einen Höhenversatz zu vermeiden. Außerdem gewährt der Spalt 19 eine gewisse Nachgiebigkeit des Arretierhakens 7. Er hat eine Stelle mit seiner geringsten Dicke, die sich dort befindet, wo die Arretiernut 11 am tiefsten ist. Die hierdurch gewonnene Nachgiebigkeit kann genutzt werden, weil der Spalt 19 Platz schafft, in den hinein eine Verformung stattfinden kann.There is a gap 19 between the inclined section 11b of the groove base of the locking groove and the inclined section 8b of the upper side of the receiving edge 8. This favors avoiding a height offset at the joint F on the top of the panel 1a. In addition, the gap 19 allows a certain flexibility of the locking hook 7. It has a point with its smallest thickness, which is located where the locking groove 11 is the deepest. The flexibility obtained in this way can be used because the gap 19 creates space into which deformation can take place.

Fig. 4a zeigt ein Detail, welches einen Ausschnitt vergrö-ßert, der in Fig. 4 mit IVa vermerkt ist. In Fig. 4a ist der Rastvorsprung 15 am Aufnahmehaken 6 vorgesehen, nämlich an der Außenseite 8a des Aufnahmerands 8. Die Rastvertiefung ist am Arretierhaken 7 vorgesehen und dort an einer zurückversetzten Nutflanke 11a der Arretiernut 11. Fig. 4a shows a detail, which enlarges a section, which in Fig. 4 is noted with IVa. In Fig. 4a the locking projection 15 is provided on the receiving hook 6, namely on the outside 8a of the receiving edge 8. The locking recess is provided on the locking hook 7 and there on a recessed groove flank 11a of the locking groove 11.

Bei einer Alternative, welche im Ausschnitt gemäß Fig. 4b gezeigt ist, sind die Positionen von Rastvertiefung und Rastvorsprung vertauscht. Hier ist eine Rastvertiefung 15a am Aufnahmehaken 6 angeordnet und zwar an der Außenseite 8a des Aufnahmerands 8. Ein Rastvorsprung 16a ist dann am Arretierhaken 7 vorgesehen, nämlich an dessen zurückversetzter Nutflanke 11a der Arretiernut 11 vorgesehen.In an alternative, which in the cutout according Fig. 4b is shown, the positions of the locking recess and locking projection are interchanged. Here, a locking recess 15a is arranged on the receiving hook 6, specifically on the outside 8a of the receiving edge 8. A locking projection 16a is then provided on the locking hook 7, namely on the recessed groove flank 11a of the locking groove 11.

Ein weiteres Ausführungsbeispiel für ein Paneel mit besonderen Hakenprofilen schlägt Fig. 5 vor. Dieses geht vom Ausführungsbeispiel der Figuren 3 und 4 aus. Von diesem unterscheidet es sich durch eine zusätzliche obere Verrastung 20.Another embodiment for a panel with special hook profiles suggests Fig. 5 in front. This goes from the embodiment of Figures 3 and 4 out. It differs from this by an additional upper catch 20.

Die obere Verrastung 20 weist am Arretierhaken 7 ein erstes Rastmittel in Form eines Rastvorsprungs 21 auf, welches an der Außenseite 10b des Arretierrands 10 angeordnet ist. Es wirkt zusammen mit einem dazu korrespondierenden zweiten Rastmittel am Aufnahmehaken 6, das an der zurückversetzten Nutflanke 9b der Aufnahmenut 9 vorgesehen ist. Das zweite Rastmittel bildet eine Rastvertiefung 22, wie am besten in dem Ausschnitt gemäß Fig. 5a zu erkennen ist. Fig. 5a vergrößert das Detail, das in Fig. 5 mit Va bezeichnet ist.The upper catch 20 on the locking hook 7 has a first locking means in the form of a locking projection 21, which is arranged on the outside 10b of the locking edge 10. It acts together with a corresponding second latching means on the receiving hook 6, which is provided on the recessed groove flank 9b of the receiving groove 9. The second latching means forms a latching recess 22, as best shown in the cutout Fig. 5a can be seen. Fig. 5a magnifies the detail that in Fig. 5 is denoted by Va.

Bei einer Alternative, die im Ausschnitt gemäß Fig. 5b gezeigt ist, sind die Positionen von Rastvertiefung und Rastvorsprung vertauscht. Hier ist eine Rastvertiefung 21a am Arretierhaken, nämlich an der Außenseite des Arretierrands 10 angeordnet. Ein Rastvorsprung 22a ist am Aufnahmehaken vorgesehen und zwar an der zurückversetzten Nutflanke 9b der Aufnahmenut 9.In an alternative, the cutout according to Fig. 5b is shown, the positions of the locking recess and locking projection are interchanged. Here, a locking recess 21a is arranged on the locking hook, namely on the outside of the locking edge 10. A locking projection 22a is provided on the receiving hook, specifically on the recessed groove flank 9b of the receiving groove 9.

Das Ausführungsbeispiel der Fig. 6 zeigt Hakenprofile, die ausgehend von den Figuren 3 und 4 eine Änderung aufweisen und zwar ist im gezeigten verriegelten Zustand der Hakenprofile ein Freiraum 23 gebildet, der sich zwischen dem Nutgrund 9a der Aufnahmenut 9 des Aufnahmehakens 6 und einer Unterseite 10a des Arretierrands 10 des Arretierhakens 7 erstreckt. Der Freiraum 23 reicht bis an die Außenseite 10b des Arretierrands 10 heran beziehungsweise bis an die zurückversetzte Nutflanke 9b der Aufnahmenut 9 heran. Der Freiraum 23 kann Schmutzpartikel oder andere lose Partikel aufnehmen. Bei Paneelen aus Holzwerkstoffen können sich beispielsweise Partikel von der Paneelkante ablösen. Abgelöste sollen nicht zwischen die Fügeflächen der Hakenprofile gelangen und sich dort festsetzen, weil sie andernfalls eine positionsrichtige Verriegelung der Hakenprofile behindern. Zwischen der Unterseite 10a des Arretierrands 10 und dem Nutgrund 9a der Aufnahmenut 9 ist der in Fig. 6 vorgeschlagene Freiraum 23 spaltförmig ausgebildet. Der spaltförmige Freiraum 23 wird zum Nutgrund 9a hin weiter und schafft auf diese Weise den gewünschten Platz zur Aufnahme unerwünschter Partikel.The embodiment of the Fig. 6 shows hook profiles based on the Figures 3 and 4 have a change, namely in the locked state of the hook profiles shown, a free space 23 is formed, which extends between the groove bottom 9a of the receiving groove 9 of the receiving hook 6 and an underside 10a of the locking edge 10 of the locking hook 7. The free space 23 extends up to the outside 10b of the locking edge 10 or up to the recessed groove flank 9b of the receiving groove 9. The free space 23 can accommodate dirt particles or other loose particles. In the case of panels made of wood-based materials, for example, particles can detach from the edge of the panel. Detached should not get between the joining surfaces of the hook profiles and get stuck there, because otherwise they prevent a correct locking of the hook profiles. Between the bottom 10a of the locking edge 10 and the groove base 9a of the receiving groove 9 is in Fig. 6 proposed free space 23 formed in a gap. The slit-shaped Free space 23 continues towards groove base 9a and in this way creates the desired space for receiving undesired particles.

Das Ausführungsbeispiel der Fig. 7 zeigt Hakenprofile, die ebenfalls ausgehend von den Figuren 3 und 4 eine Änderung aufweisen und zwar so, dass wiederum im verriegelten Zustand der Hakenprofile ein Freiraum 24 ausgebildet ist, der sich zwischen dem Nutgrund 9a der Aufnahmenut 9 des Aufnahmehakens 6 und einer Unterseite 10a des Arretierrands 10 des Arretierhakens 7 erstreckt. Der Freiraum 24 reicht bis an die untere Verriegelungsfläche 12 des Aufnahmehakens 6 beziehungsweise bis an die obere Verriegelungsfläche 13 des Arretierhakens 7 heran. Um den Freiraum 24 zu schaffen, ist die Unterseite 10a des Arretierrands 10 mit einem flachen Absatz 24a versehen, der von der Unterseite 10a des Arretierrands 10 zurücksteht. Der Freiraum 24 kann gleichfalls Schmutzpartikel oder andere lose Partikel aufnehmen und bei Paneelen aus Holzwerkstoffen etwaige abgelöste Holzpartikel aufnehmen, die sonst zwischen den Fügeflächen der Hakenprofile festsetzen und eine positionsrichtige Verriegelung der Hakenprofile behindern würden. Der verbleibende Bereich der Unterseite 10a ist im verriegelten Zustand mit dem Nutgrund 9a der Aufnahmenut 9 in Kontakt und dadurch abgestützt.The embodiment of the Fig. 7 shows hook profiles, which are also based on the Figures 3 and 4 have a change in such a way that again in the locked state of the hook profiles a free space 24 is formed which extends between the groove base 9a of the receiving groove 9 of the receiving hook 6 and an underside 10a of the locking edge 10 of the locking hook 7. The free space 24 extends to the lower locking surface 12 of the receiving hook 6 or to the upper locking surface 13 of the locking hook 7. In order to create the free space 24, the underside 10a of the locking edge 10 is provided with a flat shoulder 24a which protrudes from the underside 10a of the locking edge 10. The free space 24 can also take up dirt particles or other loose particles and, in the case of panels made of wood-based materials, can take up any detached wood particles which would otherwise stick between the joining surfaces of the hook profiles and would hinder a correct locking of the hook profiles. The remaining area of the underside 10a is in the locked state in contact with the groove base 9a of the receiving groove 9 and is thereby supported.

Das Ausführungsbeispiel der Fig. 8 zeigt ebenfalls Hakenprofile, die von den Figuren 3 und 4 ausgehen. Gegenüber diesen Figuren ist nur die untere Verrastung 14 modifiziert worden. Gemäß Fig. 8 steht der Rastvorsprung 15 des Aufnahmehakens6 weiter von der Außenseite 8a des Aufnahmerands 8 hervor als in Fig. 4. Die Tiefe der Rastvertiefung 16 ist gegenüber Fig. 4 unverändert. Dadurch entsteht eine Lücke 25 zwischen der Außenseite 8a und der zurückversetzten Nutflanke 11a der Arretiernut 11 des Arretierhakens 7. Die Lücke 25 verbessert die Einrastbarkeit der unteren Verrastung 14.The embodiment of the Fig. 8 also shows hook profiles by the Figures 3 and 4 going out. Compared to these figures, only the lower catch 14 has been modified. According to Fig. 8 the locking projection 15 of the receiving hook 6 projects further from the outside 8a of the receiving edge 8 than in FIG Fig. 4 . The depth of the recess 16 is opposite Fig. 4 unchanged. This creates a gap 25 between the outside 8a and the recessed groove flank 11a of the locking groove 11 of the locking hook 7. The gap 25 improves the snap-in capability of the lower catch 14.

In Fig. 8a ist die untere Verrastung 14 als Ausschnitt vergrößert. Eine Alternative zu Fig. 8a zeigt der Ausschnitt gemäß Fig. 8b. Danach ist die Position von Rastvertiefung und Rastvorsprung vertauscht. Eine Rastvertiefung 15a ist nun am Aufnahmehaken 6 und zwar an der Außenseite 8a des Aufnahmerands 8 angeordnet. Ein Rastvorsprung 16a ist dafür am Arretierhaken 7 an dessen zurückversetzter Nutflanke 11a der Arretiernut 11 vorgesehen.In Fig. 8a the lower catch 14 is enlarged as a cutout. An alternative to Fig. 8a shows the section according to Fig. 8b . Then the position of the locking recess and locking projection is reversed. A latching recess 15a is now arranged on the receiving hook 6 on the outside 8a of the receiving edge 8. A locking projection 16a is provided on the locking hook 7 on its recessed groove flank 11a of the locking groove 11.
