Description

Die Erfindung betrifft einen Bodenbelag, ein Verfahren zur Herstellung eines Bodenbelags, und die Verwendung des Bodenbelags. Bodenbeläge, insbesondere Fallschutzbeläge, sind an sich bekannt. Für solche Beläge sind weiterhin Bodenbelagsplatten bzw. Belagsplatten bekannt, welche insbesondere eine Fallschutzfunktion aufweisen, d.h. dass der Belag gegenüber einer senkrecht auf die Oberfläche des Belags wirkenden Kraft energieabsorbierend wirkt, so dass eine fallende Person - etwa ein Kind auf einem öffentlichen oder privaten Kinderspielplatz - beim Auftreffen auf den Belag vergleichsweise geringe Beschleunigungskräfte erfährt. Die Verletzungsgefahr sinkt mit einer sinkenden Beschleunigungskraft.
Ferner sind Bodenbeläge bekannt, die mehrere Bodenbelagsplatten aufweisen, die an ihren aneinanderstoßenden Seiten derart miteinander - insbesondere über Verbindungselemente wie stiftartige Verbindungselemente oder dergleichen - verbunden sind, dass sich ein möglichst fugenloser Bodenbelag ergibt, der ein ansprechendes Äußeres hat, d.h. nicht mehr mit einer weiteren Abdeckschicht oder dergleichen versehen werden muss.
Bei solchen bekannten Bodenbelägen ist es häufig problematisch, dass zum einen bei der Verlegung der Bodenbelagsplatten Schwierigkeiten auftreten, wenn Verbindungselemente in zwei quer zueinander verlaufenden Richtungen eingesetzt werden sollen, insbesondere beim Verlegen der "letzten Platte". Andererseits ist es bei bekannten Bodenbelägen häufig problematisch, dass sich die entweder nur lose oder aber mit Hilfe von stiftartigen Verbindungselemente miteinander verbundenen Bodenbelagsplatten im Laufe der Zeit gegeneinander verschoben werden, so dass sich doch Fugen ergeben, die nachfolgend zu einem entweder weniger ästhetischen Erscheinungsbild des Bodenbelags oder aber sogar zu einer Funktionverminderung (insbesondere mit Blick auf die Fallschutzeigenschaften) führen können.The invention relates to a floor covering, a method for producing a floor covering, and the use of the floor covering. Floor coverings, in particular fall protection coverings, are known per se. For such coverings floor covering plates or covering plates are furthermore known, which in particular have a fall protection function, ie that the covering acts to absorb energy acting perpendicular to the surface of the covering energy absorbing, so that a falling person - such as a child on a public or private children's playground - experiences relatively low acceleration forces when hitting the surface. The risk of injury decreases with a decreasing acceleration force.
Furthermore, floor coverings are known which have a plurality of floor covering plates which are connected to one another at their abutting sides - in particular via connecting elements such as pin-like connecting elements or the like - resulting in a floor covering which is as jointless as possible, which has an appealing exterior, ie no longer with another one Covering layer or the like must be provided.
In such known floor coverings, it is often problematic that on the one hand when laying the flooring panels difficulties occur when connecting elements are to be used in two mutually transverse directions, especially when laying the "last plate". On the other hand, it is often problematic in the case of known floor coverings that the floor covering panels which are connected to each other only loosely or with the aid of pin-like connecting elements are shifted against each other over time, so that joints nevertheless result, which subsequently lead to an either less aesthetic appearance of the floor covering or even to a reduction in function (especially with regard to the fall protection properties).

Aus dem WO-A-2008/114124 sind Bodenbelagsplatte bekannt, die aus einer Fliese besteht, deren Oberfläche mit Rindsleder bedeckt ist. Diese Bodenbelagsplatten können mittels unterseitig angeordneter Verbindungselemente zu einem Bodenbelag zusammegesetzt werden.From the WO 2008/114124 Floors are known which consists of a tile whose surface is covered with cowhide. These flooring panels can be assembled by means of bottom-mounted fasteners to a floor covering.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Bodenbelag vorzuschlagen, der die Nachteile des Standes der Technik nicht aufweist und gleichzeitig kostengünstig herstellbar, sowie möglichst universell einsetzbar ist.The invention is therefore based on the object to propose a floor covering, which does not have the disadvantages of the prior art and at the same time inexpensive to produce, as well as universally applicable.

Zur Lösung dieser Aufgabe trägt eine Bodenbelagsplatte aus einem trittfesten, elastischen, vorzugsweise witterungsbeständigen Material bei, die eine als Sichtseite vorgesehene Oberseite und eine Unterseite aufweist, wobei die Bodenbelagsplatte zur Bildung eines Bodenbelags in Verbindung mit einem auf der Unterseite der Bodenbelagsplatte angeordneten Verbindungselement vorgesehen ist, wobei die Bodenbelagsplatte zur Erzielung einer Wirkverbindung mit dem Verbindungselement wenigstens eine erste Befestigungsausformung aufweist, so dass die Bodenbelagsplatte zur Herbeiführung eines zumindest teilweise fugenlosen Bodenbelags unterseitig mit dem Verbindungselement formschlüssig verbunden ist.To solve this problem, a floor covering plate contributes from an impact-resistant, elastic, preferably weather-resistant material, which has a top side provided as a visible side and a bottom, wherein the floor covering plate is provided for forming a floor covering in connection with a arranged on the underside of the floor covering plate connecting element wherein the floor covering plate to achieve an operative connection with the connecting element has at least one first Befestigungsausformung, so that the floor covering plate for bringing about an at least partially seamless floor covering is connected to the connecting element form-fitting bottom.

Bevorzugt ist vorgesehen, dass die Bodenbelagsplatte wasserdurchlässig ausgebildet ist. Dadurch ist es vorteilhaft möglich, dass Regenwasser durch die Bodenbelagsplatte in den Untergrund ablaufen kann und dass dadurch auf eine Fuge zum Wasserablauf verzichtet werden kann.It is preferably provided that the floor covering plate is formed permeable to water. Thus, it is advantageously possible that rainwater can drain through the floor covering plate into the ground and that this can be dispensed with a joint to the water outlet.

Bevorzugt zieht das Verbindungselement aneinanderliegende Bodenbelagsplatten aufeinander zu. Dadurch ist zum Einen ein fugenloses Verlegen möglich und zum Anderen wird ein Verschieben der Bodenbelagsplatten gegeneinander verhindert. Insbesondere ist ungewünschtes "Knarzen", also Geräusche, die z.B. durch das Aneinanderreiben der Platten entstehen, vermeidbar.The connecting element preferably pulls adjacent floor covering panels towards one another. As a result, on the one hand a jointless laying is possible and on the other hand, a displacement of the flooring panels is prevented against each other. In particular, unwanted "creaking", that is, noise, e.g. caused by the rubbing together of the plates, avoidable.

Der Begriff Bodenbelagsplatte schließt erfindungsgemäß alle Formen plattenförmiger Körper ein, unabhängig von ihrer Umfangsgeometrie. Hierzu gehören Platten, die in der Aufsicht rechteckig, dreieckig, rhombisch, sechseckig, achteckig oder trapezförmig sind, unabhängig von ihrer Länge, Breite, Seiten- bzw. Kantenlänge bzw. Dicke. Eine beispielhafte Platte hat eine Oberfläche von 0,1 m2 bis 10 m2 und eine Dicke von 10 mm bis 500 mm. Der Begriff Bodenbelagsplatte erstreckt sich primär auf Bauelemente mit planer Oberseite, schließt erfindungsgemäß aber auch solche Bauteile ein, die auf mindestens einer ihrer Oberflächen beispielsweise eine leichte Riffelung, Noppen oder sonstige Strukturen aufweisen (einschließlich randseitiger Fasungen etc.), solange sich insgesamt eine im Wesentlichen plane Funktionsoberfläche ergibt, um den Zweck eines Belags zu erfüllen.The term floorboard according to the invention includes all forms of plate-shaped body, regardless of their circumferential geometry. These include slabs that are rectangular, triangular, rhombic, hexagonal, octagonal or trapezoidal in plan, regardless of their length, width, side or edge length or thickness. An exemplary plate has a surface area of 0.1 m 2 to 10 m 2 and a thickness of 10 mm to 500 mm. The term flooring panel extends primarily to components with a flat top, but according to the invention also includes such components, on at least one of its surfaces, for example, a have slight corrugation, knobs or other structures (including edge-side chamfers, etc.), as long as the overall results in a substantially planar functional surface to fulfill the purpose of a covering.

Die Materialdicke der Bodenbelagsplatte kann beispielsweise 30 mm oder 40 mm oder 50 mm betragen, wobei anderer Materialdicken in einem Bereich von etwa 10 mm bis etwa 100 mm möglich sind und je nach gewünschter Anwendung sinnvoll sein können.The material thickness of the floor covering plate may for example be 30 mm or 40 mm or 50 mm, wherein other material thicknesses in a range of about 10 mm to about 100 mm are possible and depending on the desired application may be useful.

Der Begriff "fugenlos" ist im technischen Sinne zu verstehen, d.h. zwischen korrespondierenden Abschnitten der Randzone benachbarter Bodenbelagsplatten soll maximal ein durch Herstellungs- oder Verlegetoleranzen bedingter Abstand bestehen.The term "seamless" is to be understood in a technical sense, i. between corresponding sections of the edge zone of adjacent floor tiles should be a maximum conditional by manufacturing or laying tolerances distance.

Soweit nachstehend von "oben", "unten", "Oberseite", "Unterseite", "vertikal", "horizontal" etc. gesprochen wird beziehen sich diese Ortsangaben auf die bestimmungsgemäße Verwendung bzw. Verlegung der Bodenbelagsplatten für einen Bodenbelag. Auf diesen Anwendungszweck bezieht sich die folgende Beschreibung, ohne die Erfindung diesbezüglich einzuschränken.As far as hereinafter referred to as "top", "bottom", "top", "bottom", "vertical", "horizontal", etc., these locations refer to the intended use or installation of floor tiles for a floor covering. The following description refers to this application without restricting the invention in this respect.

Die Bodenbelagsplatte umfasst somit in einer bevorzugten Ausgestaltung der Erfindung ein mit einem Bindemittel versetztes Kunststoffgranulat, vorzugsweise Gummigranulat. Vorzugsweise ist das Gummigranulat ein EPDM (Ethylen, Propylen, Dien-Monomer)-Gummigranulat. Dieses dem Fachmann bekannte EPDM-Gummigranulat besitzt zum einen ein im gesamten Korn durchgehende gleiche Färbung. Zum anderen verfärbt sich das EPDM-Granulat auch unter starker und lang anhaltender Sonneneinstrahlung nicht wesentlich, wodurch in ganz besonders bevorzugter Weise eine Bodenbelagsplatte herstellbar ist, welche eine dauerhaft gleichbleibende Färbung der erfindungsgemäßen Bodenbelagsplatte erlaubt. Ebenfalls bevorzugt ist, dass die Bodenbelagsplatte ein Polyurethan (PU)-gebundenes Gummigranulat umfasst oder auch ein zerkleinerter Kautschuk, vorzugsweise zerkleinertes Recycling-Altgummi, das beispielsweise durch die Zerkleinerung von Kraftfahrzeugreifen gewonnen wird. Als ein vorzugsweise elastisches Bindemittel eignet sich jedes dem Fachmann geläufige Bindemittel, mit dem die Granulatteilchen untereinander verbunden werden können. Vorzugsweise ist das Bindemittel Polyurethan (PU), mit dem die Granulatteilchen vorzugsweise vollständig ummantelt werden bzw. sind.Most preferably, a floor covering plate is provided, wherein the material of the floor covering plate is a polyurethane (PU) -bound rubber granules, preferably ethylene, propylene, diene, monomer (EPDM) gum granules, or a recycled rubber granules bound with a binder, preferably PU , The floor covering plate thus comprises in a preferred embodiment of the invention a mixed with a binder plastic granules, preferably rubber granules. Preferably, the rubber granules are EPDM (ethylene, propylene, diene monomer) gum granules. This known to the expert EPDM rubber granulate has on the one hand throughout the grain continuous same color. On the other hand, the EPDM granules are not discolored even under strong and prolonged solar radiation, which in a very particularly preferred manner, a floor covering plate can be produced, which allows a permanent uniform coloration of the floor covering plate according to the invention. It is likewise preferred that the floor covering plate is a polyurethane (PU) -bonded Rubber granulate comprises or a comminuted rubber, preferably crushed recycled waste rubber, which is obtained for example by the comminution of motor vehicle tires. As a preferably elastic binder is any known in the art binder, with which the granules can be interconnected. Preferably, the binder is polyurethane (PU), with which the granules are preferably completely coated or are.

Dadurch, dass die Bodenbelagsplatte erfindungsgemäß elastisch vorgesehen ist, bzw. aus einem elastischen Material wie z.B. Gummimaterial oder Gummigranulatmaterial gefertigt ist, ist eine besonders einfache Montage des Bodenbelags möglich. Denn durch die Elastizität sind aneinanderliegende Bodenbelagsplatten stauchbar, sodass Fertigungstoleranzen bezüglich der Ausmaße der Bodenbelagsplatten und/oder des Verbindungselements auf einfache Weise ausgeglichen werden können. Erfindungsgemäß ist zudem vorgesehen, dass die Bodenbelagsplatte mit mindestens einer ersten Schicht, vorzugsweise aus durch geschäumten Kunststoff verbundenem Gummigranulat gebildet, und einer zweiten Schicht ausgebildet ist, wobei die zweite Schicht bevorzugt ebenfalls aus Gummigranulat besteht. Die erste Schicht ist an der Oberseite der Bodenbelagsplatte angeordnet. Die erste Schicht dient dabei insbesondere dem Fallschutz. Bevorzugt ist die zweite Schicht unter der ersten Schicht angeordnet, d.h. die zweite Schicht ist im montierten Zustand zwischen der ersten Schicht und dem Untergrund angeordnet. Bevorzugt ist die zweite Schicht zum Ausgleich von Bodenunebenheiten vorgesehen und ist härter bzw. nicht so elastisch wie die erste Schicht vorgesehen. Erfindungsgemäß weist die zweite Schicht eine höhere Gummigranulatdichte auf als die erste Schicht. Die zweite Schicht dient insbesondere zur Stabilisierung der Bodenbelagsplatte auf dem Untergrund. Bevorzugt ist vorgesehen, dass zwischen Gummigranulatteilchen der ersten Schicht durchgehende Zwischenräume vorgesehen sind. Dadurch ist vorteilhaft ein verbesserter Wasserablauf erreichbar. Weiterhin ist bevorzugt vorgesehen, dass die zweite Schicht Öffnungen aufweist, wobei die Öffnungen im Wesentlichen senkrecht zur Haupterstreckungsebene der zweiten Schicht angeordnet sind. Weiter bevorzugt sind im Grenzbereich zwischen der ersten Schicht und der zweiten Schicht parallel zur zweiten Schicht verlaufende Kanäle angeordnet, sodass ein verbesserter Ablauf von Regenwasser möglich ist. Die durch das Verbindungselement erzeugte Stauchung erfolgt dabei bevorzugt in der ersten Schicht. Bevorzugt steht die erste Schicht zumindest teilweise über die zweite Schicht über. Das Verbindungselement ist mit der zweiten Schicht verbunden, sodass das Verbindungselement Zug- bzw. Druckkräfte auf die zweite Schicht überträgt. Dadurch, dass die zweite Schicht aus einem unelastischeren Material als die erste Schicht besteht, ist eine vergleichsweise stabile Verbindung zwischen aneinanderliegenden Bodenbelagsplatten über das Verbindungselement möglich. Besonders bevorzugt ist das Material des Verbindungselement unelastischer als die erste Schicht und elastischer als die zweite Schicht vorgesehen, sodass die zweite Schicht formstabil auf dem Untergrund angeordnet ist und zugleich ein fugenloses Verlegen der Bodenbelagsplatten möglich ist.
Ein Problembereich bekannter Plattenböden ist der Fugenbereich zwischen benachbarten Platten, im Hinblick auf Verschleiß, Frost-/Taubeständigkeit, Veränderungen des Untergrunds. Es werden daher wenigstens zwei Bodenbelagsplatten vorgeschlagen, die zusammen mit einem Verbindungselement zur Bildung eines erfindungsgemäßen Bodenbelags verwendet werden. Für die Herstellung eines erfindungsgemäßen Bodenbelags werden in der Regel eine Vielzahl von Bodenbelagsplatten verwendet. Das Verbindungselement verbindet nun jeweils mindestens zwei Bodenbelagsplatten miteinander. Für den Fall von quadratischen oder rechteckigen Bodenbelagsplatten, die derart verlegt werden, dass jeweils eine Ecke von vier Bodenbelagsplatten aufeinanderstoßen, ist es vorgesehen, dass das Verbindungselement diese vier Bodenbelagsplatten miteinander verbindet. Für den Fall von quadratischen oder rechteckigen Bodenbelagsplatten, die derart verlegt werden, dass jeweils eine Ecke von zwei Bodenbelagsplatten auf eine Kante bzw. Längsseite einer anderen Bodenbelagsplatte stoßen, ist es vorgesehen, dass das Verbindungselement diese drei Bodenbelagsplatten miteinander verbindet. Für den Fall von quadratischen oder rechteckigen oder anders geformten Bodenbelagsplatten, die derart verlegt werden, dass sich im Randbereich des Bodenbelags jeweils eine Ecke von zwei Bodenbelagsplatten aufeinanderstoßen oder aber eine Ecke einer Bodenbelagsplatte auf eine Kante bzw. Längsseite einer anderen Bodenbelagsplatte stoßen, ist es vorgesehen, dass das Verbindungselement diese zwei Bodenbelagsplatten miteinander verbindet.
Es ist erfindungsgemäß besonders vorteilhaft, dass durch die Verwendung des Verbindungselements in einfacher Weise nicht nur eine dauerhaft stabile Verbindung der Bodenbelagsplatten miteinander (d.h. wenigsten zweier benachbarter Bodenbelagsplatten) realisierbar ist, sondern auch eine einfache Montierbarkeit gewährleistet ist. Dies deshalb, weil es erfindungsgemäß vorgesehen ist, dass die ersten Befestigungsausformungen (auf der Unterseite der Bodenbelagsplatten) und die dritten Befestigungsausformungen (des Verbindungselements) miteinander durch eine Bewegung senkrecht zur Haupterstreckungsebene der Bodenbelagsplatten (d.h. in der Montagesituation durch eine im Wesentlichen senkrechte Bewegung) miteinander verbunden werden können bzw. verbindbar sind. Es ergibt sich durch die Formgebung der ersten und dritten Befestigungsausformungen die Möglichkeit, dass bezüglich einer Relativbewegung der Bodenbelagsplatte relativ zum Verbindungselement (und damit auch zur benachbarten Bodenbelagsplatte) ein Formschluss erreicht wird zwischen der Bodenbelagsplatte und dem Verbindungselement. Es ist also erfindungsgemäß insbesondere nicht erforderlich, dass der Montagevorgang in einem ersten Schritt eine vertikale Bewegung einer zu montierenden Bodenbelagsplatte (relativ zu einer bereits montierten Bodenbelagsplatte bzw. einem bereits montierten Bodenbelagsplattenvebund bzw. Bodenbelag) und in einem zweiten Schritt eine horizontale Bewegung der zu montierenden Bodenbelagsplatte erforderlich ist (wie die im Fall von im Wesentlichen horizontal verlaufenden stiftartigen Befestigungselementen zwischen benachbarten Bodenbelagsplatten der Fall wäre). Im Gegenteil ist es erfindungsgemäß so, dass die Verbindung zwischen dem Verbindungselement und einer Bodenbelagsplatte durch eine einfache, im Wesentlichen vertikal verlaufende Relativbewegung (bezogen auf die Einbau- bzw. Montagesituation) erfolgt.Characterized in that the floor covering plate is provided according to the invention elastically, or is made of an elastic material such as rubber or rubber granulate material, a particularly simple installation of the floor covering is possible. Because of the elasticity adjoining floor covering plates are compressible, so that manufacturing tolerances can be compensated in terms of the dimensions of the floor covering plates and / or the connecting element in a simple manner. According to the invention, it is further provided that the floor covering plate is formed with at least one first layer, preferably made of rubber granules connected by foamed plastic, and a second layer, wherein the second layer preferably also consists of rubber granules. The first layer is disposed on the top of the floor covering plate. The first layer serves in particular the fall protection. Preferably, the second layer is arranged under the first layer, ie the second layer is arranged in the assembled state between the first layer and the substrate. Preferably, the second layer is provided to compensate for uneven floors and is harder or not as elastic as the first layer is provided. According to the invention, the second layer has a higher rubber granule density than the first layer. The second layer is used in particular for stabilizing the floor covering plate on the ground. It is preferably provided that continuous spaces are provided between rubber granulate particles of the first layer. As a result, an improved water drain is advantageously achievable. Furthermore, it is preferably provided that the second layer has openings, wherein the openings are arranged substantially perpendicular to the main extension plane of the second layer. More preferably, in the boundary region between the first layer and the second layer parallel to the second layer extending channels are arranged so that an improved drainage of rainwater is possible. The generated by the connecting element Compression is preferably carried out in the first layer. Preferably, the first layer is at least partially over the second layer. The connecting element is connected to the second layer, so that the connecting element transmits tensile or compressive forces to the second layer. The fact that the second layer consists of a more inelastic material than the first layer, a comparatively stable connection between adjacent flooring plates is possible via the connecting element. Particularly preferably, the material of the connecting element is inelastic than the first layer and provided as elastic as the second layer, so that the second layer is dimensionally stable on the ground and at the same time a jointless laying of the floor covering plates is possible.
A problem area of known slatted floors is the joint area between adjacent slabs, in terms of wear, frost / dew resistance, changes in the subsurface. There are therefore proposed at least two floor tiles, which are used together with a connecting element to form a floor covering according to the invention. For the production of a floor covering according to the invention, a multiplicity of floor covering boards are generally used. The connecting element now connects in each case at least two floor tiles with each other. In the case of square or rectangular floorboards laid in such a way that each corner of four floorboards meet, it is contemplated that the connector will join these four floorboards together. In the case of square or rectangular floor tiles laid in such a way that one corner of two floor tiles each encounter one edge of another floor tile, it is contemplated that the connector will join these three flooring tiles together. In the case of square or rectangular or other shaped flooring panels laid in such a way that one corner of two floorboards collide in the edge region of the floor covering or one corner of a floorboard encounters an edge or longitudinal side of another floorboard, it is provided that the connecting element connects these two floor tiles together.
It is particularly advantageous according to the invention that by the use of the connecting element in a simple manner not only a permanently stable connection of the floor covering plates with each other (ie least two adjacent flooring plates) can be realized, but also a simple assembly is guaranteed. This is because it is provided according to the invention that the first Befestigungsausformungen (on the underside of the floor panels) and the third Befestigungsausformungen (the connecting element) with each other by a movement perpendicular to the main extension plane of the floor panels (ie in the mounting situation by a substantially vertical movement) with each other can be connected or are connectable. It results from the shape of the first and third Befestigungsausformungen the possibility that with respect to a relative movement of the floor covering plate relative to the connecting element (and thus also to the adjacent floor covering plate) a positive connection is achieved between the floor covering plate and the connecting element. Thus, according to the invention, in particular, it is not necessary for the assembly process in a first step to be a vertical movement of a floor covering panel to be mounted (relative to an already installed floor covering panel or an already installed floor covering panel or floor covering) and in a second step a horizontal movement of the to be mounted Flooring plate is required (as would be the case in the case of substantially horizontally extending pin-like fasteners between adjacent floor tiles). On the contrary, it is according to the invention so that the connection between the connecting element and a floor covering plate by a simple, substantially vertically extending relative movement (based on the installation or mounting situation) takes place.

Ein weiterer Gegenstand betrifft ein Verbindungselement, insbesondere aus einem Kunststoffmaterial, zur Bildung eines Bodenbelags in Verbindung mit einer Bodenbelagsplatte, wobei das Verbindungselement zur Erzielung einer Wirkverbindung mit der Bodenbelagsplatte wenigstens zwei dritte Befestigungsausformungen aufweist, so dass mindestens zwei Bodenbelagsplatten zur Herbeiführung eines zumindest teilweise fugenlosen Bodenbelags auf ihren jeweiligen Unterseiten mit den wenigstens zwei dritten Befestigungsausformungen des Verbindungselements formschlüssig verbunden sind.Another object relates to a connecting element, in particular made of a plastic material, for forming a floor covering in conjunction with a floor covering plate, wherein the connecting element for achieving an operative connection with the floor covering plate has at least two third Befestigungsausformungen, so that at least two floor tiles for bringing about an at least partially jointless floor covering on their respective undersides with the at least two third Befestigungsausformungen of the connecting element are positively connected.

Erfindungsgemäß kommt es insbesondere auf die Wechselwirkung zwischen dem Verbindungselement und der Bodenbelagsplatte an, nämlich für den Fall, dass ein Verbindungselement mit mindestens zwei Bodebelagsplatten verbunden wird, nämlich wenigstens einer ersten Bodenbelagsplatte und einer zweiten Bodenbelagsplatte. Es ist dann die erste Verbindungsausformung der ersten Bodenbelagsplatte mit der einen der mindestens zwei dritten Verbindungsausformungen des Verbindungselements verbunden und es ist ferner die erste Verbindungsausformung der zweiten Bodenbelagsplatte mit der anderen der mindestens zwei dritten Verbindungsausformungen des Verbindungselements verbunden. Bevorzugt weist jedoch das Verbindungselement drei dritte Befestigungsausformungen auf bzw. es weist das Verbindungselement vier dritte Befestigungsausformungen auf.According to the invention, in particular, the interaction between the connecting element and the floor covering plate, namely in the case that a connecting element is connected to at least two Bodebelagsplatten, namely at least a first floor covering plate and a second floor covering plate. Then, the first connection formation of the first floor covering plate is connected to the one of the at least two third connection formations of the connection element, and further the first connection formation of the second floor covering plate is connected to the other of the at least two third connection formations of the connection element. Preferably, however, the connecting element has three third Befestigungsausformungen or it has the connecting element four third Befestigungsausformungen.

Erfindungsgemäß ist es besonders bevorzugt, wenn die erste Befestigungsausformung der Bodenbelagsplatte eine Ausnehmung auf der Unterseite der Bodenbelagsplatte ist, insbesondere eine im wesentlichen runde Ausnehmung, bzw. wenn die dritten Befestigungsausformungen des Verbindungselements noppenartig ausgebildet ist, und insbesondere eine Verraststruktur aufweisen.. Hierdurch kann in einfacher Weise ein gute Befestigung zwischen der Unterseite der Bodenbelagsplatte und einem der dritten Befestigungsausformungen des Verbindungselements realisiert werden. Die Verraststruktur kann erfindungsgemäß beispielsweise derart vorgesehen sein, dass die dritten Befestigungsausformungen an ihrer (beispielsweise zylindrisch geformten äußeren) Oberfläche, welche an der entsprechend ausgeformten (inneren) Oberfläche der ersten Befestigungsausformungen anliegt bzw. diese berührt, mit einer Riffelung bzw. einer widerhakenartigen Riffelung (beispielsweise einer sägezahnförmigen Riffelung) derart versehen ist, dass eine solche Riffelung in der Einbausituation waagerecht verläuft, so dass bei einmal ineinandergeschobener ersten und dritten Befestigungsausformung ein guter Halt realisiert wird, d.h. das Verbindungselement kann nicht oder nur schwer von der Bodenbelagsplatte gelöst werden, wodurch im Einbauzustand ein guter Halt realisiert wird. Erfindungsgemäß ist es beispielsweise vorgesehen, eine, zwei, drei, vier, fünf oder sechs Rillen im wesentlichen waagerecht verlaufend auf der Oberfläche der dritten Befestigungsausformung vorzusehen. Hierbei kann es erfindungsgemäß vorgesehen sein, dass der Nenndurchmesser der dritten Befestigungsausformung größer ist als die lichte Weite (der Nenndurchmesser) der ersten Befestigungsausnehmung, so dass eine Verbindung des Verbindungselements mit der Bodenbelagsplatte nur unter (geringfügiger) Verformung der Materialien der beiden Befestigungsausnehmungen erfolgen kann und durch die Materialspannung ein fester Sitz ermöglicht wird. Erfindungsgemäß ist es insbesondere vorgesehen, dass das eines der Materialien der ersten bzw. dritten Befestigungsausformung eine geringere Härte aufweist (bzw. weicher ist) als das jeweilige andere Material (zumindest im Oberflächenbereich der sich gegenüberliegenden (im Wesentlichen vertikal verlaufenden) Oberflächen). Besonders bevorzugt ist das Material des Verbindungselements (und damit bei einer bevorzugten einstückigen Ausführung des Verbindungselements auch das Material der Oberfläche der dritten Befestigungsausformung) härter vorgesehen als das Material der ersten Verbindungsausformung (d.h. bei einer bevorzugten einstückigen Ausgestaltung der Bodenbelagsplatte auch das Material der Bodenbelagsplatte).According to the invention it is particularly preferred if the first Befestigungsausformung the floor covering plate is a recess on the underside of the floor covering plate, in particular a substantially circular recess, or if the third Befestigungsausformungen of the connecting element is knob-like, and in particular have a latching structure a simple way of a good attachment between the bottom of the floor covering plate and one of the third Befestigungsausformungen the connecting element can be realized. The latching structure according to the invention may be provided, for example, such that the third Befestigungsausformungen on its (for example, cylindrically shaped outer) surface, which rests against the correspondingly shaped (inner) surface of the first Befestigungsausformungen or touches, with a corrugation or a barb-like corrugation ( For example, a saw-toothed corrugation) is provided such that such a corrugation runs horizontally in the installation situation, so that when once nested first and third Befestigungsausformung a good fit is realized, ie the connecting element can not or only with difficulty from the floor covering plate be, which is realized in the installed state, a good grip. According to the invention, it is for example provided to provide one, two, three, four, five or six grooves substantially horizontally extending on the surface of the third Befestigungsausformung. It may be provided according to the invention that the nominal diameter of the third Befestigungsausformung is greater than the clear width (the nominal diameter) of the first mounting recess, so that a connection of the connecting element with the floor covering plate can be made only under (minor) deformation of the materials of the two Befestigungsausnehmungen and a tight fit is made possible by the material tension. According to the invention, it is provided, in particular, that one of the materials of the first or third attachment formation has (or is softer) less hardness than the respective other material (at least in the surface area of the opposing (substantially vertical) surfaces). Particularly preferably, the material of the connecting element (and thus in a preferred integral embodiment of the connecting element and the material of the surface of the third Befestigungsausformung) provided harder than the material of the first Verbindungsausformung (ie in a preferred one-piece embodiment of the floor covering also the material of the floor covering plate).

Erfindungsgemäß ist es weiterhin bevorzugt vorgesehen, dass die Bodenbelagsplatte eine zweite Befestigungsausformung zur Realisierung einer Schwenklagenstabilisierung der Bodenbelagsplatte relativ zum Verbindungselement aufweist bzw. dass das Verbindungselement ferner wenigstens zwei vierte Befestigungsausformungen zur Realisierung einer Schwenklagenstabilisierung der wenigstens zwei Bodenbelagsplatten relativ zum Verbindungselement aufweist. Es ist hierdurch erfindungsgemäß vorteilhaft möglich, dass nicht nur ein Formschluss gegenüber einer Zugkraftbeaufschlagung zwischen zwei benachbarten Bodebelagsplatten von dem Verbindungselement bzw. von den jeweiligen Befestigungsausformungen aufgenommen werden kann, sondern dass auch eine Stabilisierung des Verbindungselements und einer Bodenbelagsplatte gegenüber einer Relativdrehung (bzw. Schwenkung) des Verbindungselements relativ zur Bodenbelagsplatte erzielt werden kann. Hierzu ist beispielsweise vorgesehen, dass die zweite Befestigungsausformung (auf der Unterseite der Bodenbelagsplatte) kanalartig derart vorgesehen ist, dass sie einen Ausleger des Verbindungselements formschlüssig umgreift. Hierdurch kann erreicht werden, dass auch diese Formschlussverbindung einer Verschiebung der Bodebelagsplatten relativ zueinander entgegenwirkt.According to the invention it is further preferably provided that the floor covering plate has a second Befestigungsausformung for realizing a Schwenklagen stabilization of the floor covering plate relative to the connecting element or that the connecting element further comprises at least two fourth Befestigungsausformungen for realizing a Schwenklagenstabilisierung the at least two flooring plates relative to the connecting element. It is thus advantageous according to the invention possible that not only a positive engagement with a Zugkraftbeaufschlagung between two adjacent Bodebelag plates can be absorbed by the connecting element or by the respective Befestigungsausformungen, but also that a stabilization of the connecting element and a floor covering against relative rotation (or pivoting) of the connecting element can be achieved relative to the floor covering plate. For this purpose, it is provided, for example, that the second Befestigungsausformung (on the underside of the floor covering plate) is channel-like provided such that it is a cantilever of the connecting element engages positively. In this way it can be achieved that also this positive connection counteracts a displacement of the Bodebelagsplatten relative to each other.

Gegenstand der vorliegenden Erfindung ist demnach ein Bodenbelag gemäß Anspruch 1. Ein solcher Bodenbelag ist vorteilhafterweise besonders formstabil über eine große Lebensdauer, wobei auch bestimmte Änderungen im Untergrund, etwa Unterspülungen oder dergleichen, in gewissen Grenzen von dem Bodenbelag derart aufgenommen werden können, dass durch die verbundartige Verbindung der den Bodenbelag bildenden Bodenbelagesplatten untereinander (vermittelt über die jeweiligen Verbindungselemente) eine verbesserte Dauerstabilität des Bodenbelags resultiert und der Bodenbelag trotzdem kostengünstig realisierbar ist und mit vergleichsweise geringem Montageaufwand verlegbar ist.
Das Verbindungselement bzw. die Mehrzahl von zur Bildung des Bodenbelags benutzten Verbindungselemente sind jeweils etwa kreuzförmig ausgebildet sind, d.h. ausgehend von einem Zentrum des Verbindungselements ragen jeweils eine Mehrzahl von armförmigen Bereichen des Verbindungselements ab. Hierbei kann es sich beispielsweise um zwei armförmige Bereiche oder um drei armförmige Bereiche oder um vier armförmige Bereiche handeln, je nach der gewünschten Geometrie des Verbindungselements, der betrachteten Einbausituation (etwa im Randbereich des Bodenbelags könnte es sinnvoll sein, lediglich zwei armförmige Bereiche vorzusehen) bzw. der Formgebung der für die Bildung des Bodenbelags verwendeten Bodenbelagsplatten. (d.h. bei rechtwinkligen Bodenbelagsplatten kommen bevorzugt Verbindungselemente in Frage die kreuzförmig mit vier armförmigen Bereichen ausgebildet sind, während bei nichtrechtwinkligen Bodenbelagsplatten (beispielsweise sechseckförmigen Bodenbelagsplatten) auch kreuzförmige Verbindungselemente mit einer anderen Anzahl von armförmigen Bereichen (etwa drei armförmigen Bereichen oder auch sechs armförmigen Bereichen) in Frage kommen.
Erfindungsgemäß weist eine Bodenbelagsplatte bevorzugt eine Mehrzahl von ersten (und gegebenenfalls zusätzlich zweiten) Befestigungsausformungen auf. Es kann dabei vorteilhaft vorgesehen sein, dass eine rechteckige Bodenbelagsplatte beispielsweise an allen vier Ecken jeweils eine erste Befestigungsausformung aufweist. Alternativ oder zusätzlich kann eine solche rechteckige Bodenbelagsplatte auch jeweils eine erste Befestigungsausformung (oder auch zwei erste Befestigungsausnehmungen) im Bereich der Mitte einer Kante bzw. Seite der Bodenbelagsplatte aufweisen. Ferner kann für eine Benutzung im Randbereich des Bodenbelags auch zwei erste Befestigungsausnehmungen im Bereich einer oder mehrerer der Ecken (insbesondere aller Ecken) einer rechteckigen Bodenbelagsplatte vorgesehen sein. Gleiches gilt für die Übertragung auf anders geformte Bodenbelagsplatten, etwa sechseckförmige Bodenbelagsplatten.
Ein weiterer Gegenstand der vorliegenden Erfindung bezieht sich auf ein Verfahren zur Herstellung eines Bodenbelags gemäß Anspruch 11. Hierdurch ist es erfindungsgemäß mit einfachen Mitteln möglich, sowohl einen sehr stabilen bzw. lebensdauerstabilen Bodenbelag herzustellen und dennoch eine leichte und einfache Montagemöglichkeit anzugeben, so dass die Montage kostengünstig durchgeführt werden kann.The subject matter of the present invention is accordingly a floor covering according to claim 1. Such a floor covering is advantageously particularly dimensionally stable over a long service life, whereby certain changes in the subsurface, such as sub-rinses or the like, can be accommodated within certain limits of the floor covering such that through the composite-like connection of the floor covering forming floor covering plates with each other (mediated by the respective connecting elements) results in an improved durability of the floor covering and the floor covering is nevertheless inexpensive to realize and can be laid with relatively little installation effort.
The connecting element or the plurality of connecting elements used for the formation of the floor covering are each formed approximately cross-shaped, ie, starting from a center of the connecting element in each case protrude from a plurality of arm-shaped areas of the connecting element. This can be, for example, two arm-shaped areas or three arm-shaped areas or four arm-shaped areas, depending on the desired geometry of the connecting element, the considered installation situation (for example in the edge area of the floor covering it might be sensible to provide only two arm-shaped areas) or the shape of the flooring for the formation of the flooring used flooring panels. (ie in rectangular floor panels are preferably connecting elements in question which are formed cross-shaped with four arm-shaped areas, while non-rectangular flooring plates (for example, hexagonal flooring panels) also cross-shaped connecting elements with a different number of arm-shaped areas (about three arm-shaped areas or six arm-shaped areas) in Question come.
According to the invention, a floor covering plate preferably has a plurality of first (and optionally additionally second) fastening formations. It can be advantageously provided that a rectangular floor covering plate, for example, at all four corners each having a first Befestigungsausformung. Alternatively or additionally, such a rectangular floor covering plate also each have a first Befestigungsausformung (or two first mounting recesses) in the region of the center of an edge or side of the floor covering plate. Furthermore, for use in the edge region of the floor covering, two first fastening recesses may also be provided in the region of one or more of the corners (in particular of all corners) of a rectangular floor covering plate. The same applies to the transfer to differently shaped flooring panels, such as hexagonal flooring panels.
Another object of the present invention relates to a method for producing a floor covering according to claim 11. Thus, it is possible according to the invention by simple means to produce both a very stable or life-stable flooring and yet provide a simple and easy installation option, so that the installation can be carried out inexpensively.

Am Beispiel eines Verbindungselements 20 zur Verbindung zweier aneinanderstoßender Bodenbelagsplatten 10 ist dieser Zusammenhang in den Figuren 4 (in einer Seitenansicht) und 5 (in einer Draufsicht) in vergrößerter Darstellung dargestellt. Die armförmigen Bereiche 20" des Verbindungselements 20 tragen jeweils an ihrem dem Zentrum 20' des Verbindungselements 20 abgewandten Ende eine Befestigungsausformung, bevorzugt in Form einer noppenartigen (nach oben hin orientierten) Befestigungsausformung zum Eingriff in eine korrespondierende Befestigungsausnehmung in der Unterseite der jeweiligen Bodenbelagsplatte 10. Die Befestigungsausformung der Bodenbelagsplatte 10 bzw. der Mehrzahl von Bodenbelagsplatten 10 wird nachfolgend als erste Befestigungsausformung 15 bezeichnet. Die Befestigungsausformung des Verbindungselements 20 wird nachfolgend als dritte Befestigungsausformung 25 bezeichnet.The example of a connecting element 20 for connecting two adjoining floor covering panels 10, this relationship is in the FIGS. 4 (in a side view) and 5 (in a plan view) shown in an enlarged view. The arm-shaped regions 20 "of the connecting element 20 each carry at their end facing away from the center 20 'of the connecting element 20 a Befestigungsausformung, preferably in the form of a knob-like (upward oriented) Befestigungsausformung for engagement in a corresponding mounting recess in the bottom of the respective floor covering plate 10th The attachment formation of the floor covering plate 10 or of the plurality of floor covering plates 10 is referred to below as the first fastening formation 15. The fastening formation of the connecting element 20 is referred to below as the third attachment formation 25.

Neben den ersten und dritten Befestigungsausformungen 15, 25 kann es erfindungsgemäß vorgesehen sein, dass zweite und vierte Befestigungsausnehmungen 16, 26 dafür sorgen, dass es bei an eine Bodenbelagsplatte 10 montiertem Verbindungselement 20 nicht nur zu einem Formschluss gegenüber einer Zugkraft in Richtung zum Zentrum 20' des Verbindungselements 20 kommt, sondern auch zu einem Formschluss gegenüber einer Relativdrehung (bzw. Schwenkung) des Verbindungselements 20 (etwa um eine gedachte Drehachse, die sich im Bereich des Zentrums der ersten Verbindungsausformung 15 befinden würde). Hierzu ist beispielsweise die zweite Befestigungsausnehmung 16 kanalartig auf der Unterseite 12 einer Bodenbelagsplatte 10 derart vorgesehen, dass einer der armförmigen Bereiche 20" nur in einer Drehlage mit der Bodenbelagsplatte 10 verbunden werden kann, entsprechend ist der armförmige Bereich des Verbindungselements 20 als vierte Befestigungsausnehmung anzusehen. Die Oberseite 11 der Bodenbelagsplatte 10 ist bevorzugt plan bzw. glatt ausgebildet, kann jedoch auch strukturiert sein.In addition to the first and third fastening formations 15, 25, it can be provided according to the invention that second and fourth fastening recesses 16, 26 ensure that, in the case of a connecting element 20 mounted on a floor covering plate 10, not only a positive connection with respect to a tensile force in the direction of the center 20 '. of the connecting element 20 comes, but also to a positive connection a relative rotation (or pivoting) of the connecting element 20 (about an imaginary axis of rotation, which would be in the region of the center of the first Verbindungsausformung 15). For this purpose, for example, the second mounting recess 16 channel-like on the bottom 12 of a floor covering plate 10 is provided such that one of the arm-shaped portions 20 "can be connected only in a rotational position with the floor covering plate 10, accordingly, the arm-shaped portion of the connecting element 20 is to be regarded as a fourth mounting recess. The upper side 11 of the floor covering plate 10 is preferably flat or smooth, but may also be structured.

In Figur 4 ist spezifisch das Montageverfahren bzw. das Herstellungsverfahren zur Bildung des Bodenbelags schematisch dargestellt. Von zwei Bodenbelagsplatten 10 wird hierzu eine erste Bodenbelagsplatte mit dem Bezugszeichen 10' und eine zweite Bodenbelagsplatte mit dem Bezugszeichen 10" bezeichnet. Beide Bodenbelagsplatten 10 (bzw. 10', 10") weisen jeweils mindestens eine erste Befestigungsausformung 15. Bevorzugt weisen die Bodenbelagsplatten 10 (bzw. 10', 10") jeweils sowohl mindestens eine erste Befestigungsausformung 15 als auch mindestens eine zweite Befestigungsausformung 16 auf. Das Verbindungselement 20 wird mit seiner dritten Befestigungsausformung 25 mit den jeweiligen ersten Befestigungsausformungen 15 der Bodenbelagsplatten 10', 10" verbunden. Im Falle von zusätzlich vorhandenen zweiten Befestigungsausformungen 16 in den Bodenbelagsplatten 10', 10" wird bei diesem Verbindungsvorgang bzw. Steckvorgang (vgl. die Pfeilldarstellung zwischen dem Verbindungselement 20 und den Bodenbelagsplatten 10', 10") auch die jeweilige vierte Befestigungsausformung 26 mit den jeweiligen zweiten Befestigungsausformungen 16 der Bodenbelagsplatten 10', 10" verbunden. Hierbei ist es erfindungsgemäß besonders vorteilhaft, wenn die Verbindung zwischen der ersten Befestigungsausformung 15 (bevorzugt als Befestigungsausnehmung) und der zweiten Befestigungsausformung 16 (bevorzugt als noppenartige, insbesondere zylinderförmige, nach oben ragende Ausformung) einen gewissen Schutz gegenüber einem Lösen der Verbindung (d.h. einer Relativbewegung zwischen Bodenbelagsplatte 10 und Verbindungselement 20 in vertikaler Richtung) bietet, etwa durch eine Riffelung der Oberfläche der ersten und oder dritten Verbindungsausformung 15, 16 und/oder durch eine derartige Dimensionierung, dass ein dauerhafter Spannungszustand in den beteiligten Materialien realisiert ist. Eine entsprechende Lösehemmung kann auch zwischen der zweiten Verbindungsausformung 16 und der vierten Verbindungsausformung 26 vorgesehen sein.
Fig. 6 zeigt schematisch eine weitere beispielhafte Ausführungsform der vorliegenden Erfindung. Die Bodenbelagsplatten 10', 10" weisen im Vergleich zur nicht erfindungsgemäßen Ausführungsform aus Fig. 4 jeweils eine elastische erste Schicht 60 bzw. 60' auf sowie eine unelastischere zweite Schicht 62 bzw. 62' auf. Die gestrichelte Linie 61 deutet einen Übergangsbereich zwischen den ersten Schichten 60, 60' und den zweiten Schichten 62, 62' an. Die Befestigungsausformungen 15, 16 sind in den zweiten Schichten 62, 62' angeordnet, sodass eine vergleichsweise stabile Verbindung der Bodenbelagsplatten 10, 10' über das Verbindungselement 20 erreicht werden kann. Die erste Schicht 60, 60' besteht bevorzugt aus einem Gummigranulat. Die zweite Schicht 62, 62' besteht bevorzugt aus einem unelastischeren Material als die erste Schicht, wie z.B. aus einem Gummigranulat mit höherer Dichte als die erste Schicht.
