Description

Die Erfindung betrifft gemäß den Merkmalen im Oberbegriff von Patentanspruch 1 einen Fußbodenbelag, welcher aus einem Plattenverbund besteht, dessen Platten miteinander in Eingriff bringbar sind.The invention relates according to the features in the preamble of claim 1, a floor covering which consists of a plate composite whose plates are engageable with each other.

In der DE 10 2005 062 982 B3 wird ein Plattenverbund beschrieben, dessen benachbarte Platten durch ein nachträgliches Einschieben einer Kopffeder miteinander verriegelt werden. Hierzu werden die Platten zunächst in einer Montagelage miteinander in rastenden Eingriff gebracht. In einem Verriegelungskanal zwischen benachbarten Platten wird anschließend die Kopffeder eingeschoben, so dass die Platten nicht mehr gegeneinander bewegt werden können. Trotz der hierbei erzielbaren einfachen Verlegbarkeit der Platten ist beim manuellen Einsetzen einer Kopffeder ein zusätzlicher Arbeitsschritt notwendig.In the DE 10 2005 062 982 B3 a plate composite is described, the adjacent plates are locked together by a subsequent insertion of a head spring. For this purpose, the plates are first brought into locking engagement with each other in an assembly position. In a locking channel between adjacent plates, the head spring is then inserted, so that the plates can no longer be moved against each other. Despite the achievable here simple installation of the plates, an additional step is necessary for manual insertion of a head spring.

Zum Stand der Technik sind die EP 1 277 896 A1 , DE 10 2006 072 982 B3 , DE 101 592 84 A1 , DE 10 2006 024 184 A1 sowie die nachveröffentlichte US 2009/0193748 A1 zu nennen, die jeweils für sich betrachtet verschiedene Verriegelungsmethoden für Fußbodenbeläge aus einem Plattenverbund beschreiben. Die Verriegelung erfolgt teilweise nach dem Bajonettprinzip, bei welcher stirnseitig verzahnte Paneele miteinander in Eingriff gebracht werden. Die Verzahnungen sind in der Regel rechteckig konfiguriert.The state of the art is the EP 1 277 896 A1 . DE 10 2006 072 982 B3 . DE 101 592 84 A1 . DE 10 2006 024 184 A1 and the post-published US 2009/0193748 A1 to name, each of which describes different locking methods for floor coverings from a panel composite. The locking takes place partially according to the bayonet principle, in which frontally toothed panels are brought into engagement with each other. The gears are usually configured rectangular.

Der Erfindung liegt ausgehend vom Stand der Technik die Aufgabe zu Grunde, einen Fußbodenbelag aus im Verbund verlegten Platten aufzuzeigen, dessen Platten mittels eines einfachen und kostengünstig herzustellenden Verriegelungsmechanismusses miteinander verbindbar sind, ohne dass zur Verriegelung zusätzliche Verriegelungselemente montiert werden müssen.The invention is based on the prior art based on the object to show a floor covering made of composite panels whose plates are connected to each other by means of a simple and inexpensive to produce locking mechanism without additional locking elements must be mounted for locking.

Diese Aufgabe ist bei einem Fußbodenbelag mit den im Patentanspruch 1 angegebenen Merkmalen gelöst.This object is achieved in a floor covering with the features specified in claim 1.

Vorteilhafte Ausgestaltungen des Erfindungsgedankens sind Gegenstand der abhängigen Ansprüche 2 bis 13.Advantageous embodiments of the inventive concept are the subject of the dependent claims 2 to 13.

Der Fußbodenbelag besteht aus im Verbund verlegbaren Platten, wo sich benachbarte Platten über Verriegelungsleisten miteinander in rastendem Eingriff befinden. Im Folgenden wird auf die erfindungsgemäße Verbindung zweier benachbarter Platten eingegangen, wobei zur besseren Unterscheidung A als zu einer A-Platte gehörend und B als zu einer benachbarten B-Platte gehörend bedeutet. Insgesamt sind die Platten vorzugsweise identisch konfiguriert, wobei die zueinander weisenden Kopf- und Längsseiten zweier benachbarter Platten zueinander komplementär ausgebildet sind.The floor covering consists of composite laid panels, where adjacent panels are latchingly engaged with each other via locking strips. In the following, reference is made to the connection according to the invention of two adjacent plates, wherein for better distinction A belongs to an A-plate and B belongs to an adjacent B-plate. Overall, the plates are preferably configured identically, wherein the mutually facing head and long sides of two adjacent plates are complementary to each other.

Erfindungsgemäß weisen die Platten an ihren Kopf- und/oder Längsseiten, A- und B-Verriegelungsleisten auf. Dabei weist eine Stirnseite einer B-Verriegelungsleiste mehrere in Längsrichtung der Stirnseite beabstandete B-Vorsprünge auf, welche zur benachbarten Platte weisend angeordnet sind. Die benachbarte Platte A weist zur B-Verriegelungsleiste weisende A-Vorsprünge auf, welche ebenfalls in Längsrichtung der B-Verriegelungsleiste beabstandet sind. Die B-Vorsprünge begrenzen eine B-Hinterschneidung, welche zur Aufnahme der A-Vorsprünge vorgesehen ist. Die A- und B-Vorsprünge können nach dem Einsetzen der A-Vorsprünge in die B-Hinterschneidung durch eine Relativbewegung in Längsrichtung der Verriegelungsleisten zumindest teilweise, vorzugsweise aber vollständig, miteinander in Überdeckung gebracht werden.According to the invention, the plates on their top and / or sides, A- and B-locking strips. In this case, an end face of a B-locking strip on a plurality of spaced apart in the longitudinal direction of the end face B-projections, which are arranged facing the adjacent plate. The adjacent plate A has B-locking bar facing A-projections, which are also spaced in the longitudinal direction of the B-locking bar. The B-protrusions define a B-undercut intended to receive the A-protrusions. The A and B projections can be at least partially, but preferably completely, brought into coincidence with each other after insertion of the A-projections in the B-undercut by a relative movement in the longitudinal direction of the locking strips.

Die B-Hinterschneidung kann in ihrem Querschnitt U-förmig konfiguriert sein, wobei die B-Vorsprünge einen Schenkel der B-Hinterschneidung bilden.The B-type undercut may be U-shaped in its cross-section, the B-type projections forming a leg of the B-type undercut.

Die A-Hinterschneidung kann in ihrem Querschnitt ebenfalls U-förmig konfiguriert sein, wobei die A-Vorsprünge einen Schenkel der A-Hinterschneidung bilden.The A-undercut may also be U-shaped in its cross-section, with the A-protrusions forming a leg of the A-undercut.

Die A- und B-Vorsprünge können in Längsrichtung der A- und B-Platten in gleich bleibendem Abstand zueinander angeordnet sein und zwar so, dass der Abstand der A-Vorsprünge zueinander gleich dem Abstand der B-Vorsprünge zueinander ist. Die Abstände zwischen mehreren B-Vorsprüngen können variieren. Wichtig ist, dass die Abstände der korrespondierenden A- und B-Vorsprünge von den jeweils benachbarten Vorsprüngen derselben Platte gleich sind. Dies ermöglicht zwischen den A- und B-Vorsprüngen einen verzahnenden Eingriff. Um diesen Eingriff zu erleichtern, können an den Kanten der A- und/oder B-Vorsprünge Fasen vorgesehen sein.The A and B projections may be arranged in the longitudinal direction of the A and B plates at a constant distance from each other in such a way that the distance of the A-projections to each other is equal to the distance of the B-projections to each other. The distances between several B-projections may vary. It is important that the distances of the corresponding A and B projections from the respective adjacent projections of the same plate are the same. This allows a meshing engagement between the A and B protrusions. To facilitate this engagement, bevels may be provided at the edges of the A and / or B projections.

Zusätzlich können die A- oder B-Verriegelungsleisten eine oder mehrere Markierungen aufweisen, welche ein Ausrichten der Platten zueinander vor dem In-Eingriff-Bringen erleichtern. Die Markierungen können beispielsweise in Form von farblichen Markierungen oder Kerben ausgeführt sein. Die Markierungen können auch einen Bereich begrenzen, in welchem die Vorsprünge aneinander vorbeigeführt werden können, bevor sie miteinander in Überdeckung gebracht werden. Je größer der markierte Bereich ist, desto leichter lassen sich die Vorsprünge aneinander vorbei führen, ohne dass die Platten sich verhaken. Der Nachteil sehr großer markierter Bereiche ist, dass der Bereich der gegenseitigen Überdeckung der Vorsprünge in der Verriegelungsstelle entsprechend kleiner wird. Vorzugsweise sind die von den Markierungen begrenzten Bereiche, in denen ein Zusammenfügen möglich ist, nicht größer als 10 mm.In addition, the A or B locking bars may include one or more markings which facilitate alignment of the plates with each other prior to engagement. The markings may be in the form of colored markings or notches, for example. The markers may also limit a range in which the projections can be passed past each other before being overlapped with each other. The larger the marked area, the easier it is for the projections to pass one another without the panels getting caught. The disadvantage of very large marked areas is that the area of mutual overlap of the projections in the locking point is correspondingly smaller. Preferably, the areas delimited by the marks, in which joining is possible, are not greater than 10 mm.

Die A- und B-Vorsprünge erstrecken sich in einer Ebene parallel zur Sichtseite des Fußbodenbelags und sind in Richtung dieser Ebene wellenförmig ausgestaltet. Vorzugsweise sind die A- und B-Vorsprünge sinusförmig ausgestaltet. Die A- und B-Vorsprünge sind dabei feststehend. Sie bestehen vorzugsweise aus dem gleichen Material wie die Verriegelungsleisten. Hierbei wird als Material vorzugsweise ein Holzwerkstoff eingesetzt. Häufig werden hochdichte oder mitteldichte Faserplatten als Basismaterial bei der Herstellung der Platten verwendet. Dabei ist es sowohl möglich, die Verriegelungsleisten und die Vorsprünge aus einem Stück zu fertigen, als auch die Vorsprünge nachträglich an den Verriegelungsleisten anzubringen. Dazu können die A- und/oder B-Verriegelungsleisten aus einem anderen Material als die Platten, beispielsweise einem Kunststoff, gefertigt sein und werden anschließend an den Kopf- und/oder Längsseiten der Platten angeordnet. Dabei können die A- und B-Verriegelungsleisten beispielsweise über eine Steck-, Klemm-, oder/und Klebeverbindung mit den Platten verbunden sein.The A and B projections extend in a plane parallel to the visible side of the floor covering and are wave-shaped in the direction of this plane. Preferably, the A and B projections are sinusoidal. The A and B projections are fixed. They are preferably made of the same material as the locking strips. Here, a wood material is preferably used as the material. Frequently, high density or medium density fiberboard is used as the base material in the manufacture of the panels. It is both possible to manufacture the locking strips and the projections in one piece, as well as the projections later to attach to the locking strips. For this purpose, the A and / or B-locking strips may be made of a different material than the plates, for example a plastic, and are then arranged on the top and / or sides of the plates. The A and B locking strips can be connected to the plates, for example via a plug-in, clamped, and / or glued connection.

Es ist auch denkbar, dass die Verbindung der Verriegelungsleisten mit den Platten selbst als Schiebeverbindung ausgelegt ist. Dadurch ist es möglich, Platten stirnseitig miteinander zu verbinden, ohne die ganzen Platten zu verschieben. Es reicht aus, wenn nur eine oder beide der Verriegelungsleisten verschoben werden, um die Platten mittels der Verriegelungsleisten miteinander zu verbinden, wobei die Platten bei der Verrastung nicht bewegt werden. Die Verbindung zwischen der Platte und der Verriegelungsleiste kann somit eine verschiebbare Steck- oder Klemmverbindung sein. Eine Klemmverbindung ermöglicht es, die Verriegelungsleiste in einer Verriegelungsposition zu fixieren, um eine unerwünschte Entriegelung zu verhindern. Es sind aber auch andere Fixierungsmöglichkeiten denkbar, die auf den Prinzipien des Kraftschlusses, Formschlusses oder sogar Stoffschlusses einschließlich einer Klebeverbindung beruhen. Die vorgenannten Verbindungsprinzipien sind miteinander kombinierbar, z. B. durch eine Schnappverbindung, bei der eine Verriegelungsleiste formschlüssig und zugleich kraftschlüssig gehalten ist. Eine Lagefixierung kann auch durch eine in einer Fixierstellung einen Klebstoff freisetzende oder eine Klebung bewirkende Anordnung erfolgen, z. B. indem zwei Klebstoffkomponenten zusammengeführt werden, die bei gegenseitigem Kontakt aushärten.It is also conceivable that the connection of the locking strips is designed with the plates themselves as a sliding connection. This makes it possible to connect plates frontally without moving the whole plates. It is sufficient if only one or both of the locking strips are moved to connect the plates by means of the locking strips together, the plates are not moved during the latching. The connection between the plate and the locking bar can thus be a displaceable plug or clamp connection. A clamping connection makes it possible to fix the locking bar in a locking position to prevent unwanted unlocking. But there are also other fixation possibilities conceivable based on the principles of adhesion, positive fit or even material bond including an adhesive bond. The aforementioned connection principles can be combined with each other, for. B. by a snap connection, in which a locking bar is held positively and at the same time non-positively. A position fixation can also be effected by an adhesive releasing in a fixing position or an adhesive effecting arrangement, for. B. by two adhesive components are brought together, which harden in mutual contact.

Beim Verbinden zweier benachbarter Platten werden ihre A- und B-Vorsprünge zunächst zueinander versetzt angeordnet, so dass jeweils ein A-Vorsprung neben einem B-Vorsprung angeordnet ist. Durch eine vertikale Verlagerung der A- und/oder B-Platte in Hochrichtung, dass heißt quer zur Verlegeebene, werden die jeweiligen Vorsprünge aneinander vorbei geführt, so dass die Vorsprünge der einen Platte in die zugehörige A- oder B-Hinterschneidung der jeweils anderen Platte gelangen. Dies geschieht für beide Vorsprünge beziehungsweise Hinterschneidungen gleichzeitig, da die einander zugewandten Plattenseiten diesbezüglich aufeinander abgestimmt sind. Durch ein anschließendes Verschieben der Platten in Längsrichtung ihrer einander benachbarten Seiten werden die A-Vorsprünge mit den B-Vorsprüngen zumindest teilweise, vorzugsweise aber vollständig, in Deckung miteinander gebracht. Dadurch wird die anfangs zum Verbinden durchgeführte vertikale Verlagerung der benachbarten Platten behindert. Ohne dass die Überdeckung zwischen den A- und B-Vorsprüngen aufgehoben wird, können die Platten sich nicht mehr in Vertikalrichtung, dass heißt senkrecht zur Montagelage verlagern. Die Platten sind miteinander verriegelt. Dabei können die A- und/oder B-Hinterschneidungen derart ausgestaltet sein, dass die Verbindung zwischen den A-Vorsprüngen und der A-Hinterschneidung mit den B-Vorsprüngen und/oder die Verbindung zwischen den B-Vorsprüngen und der B-Hinterschneidung mit den A-Vorsprüngen im Bereich der Überdeckung zumindest teilweise formschlüssig ist.When connecting two adjacent plates their A and B projections are initially arranged offset to each other, so that in each case an A-projection is arranged adjacent to a B-projection. By a vertical displacement of the A and / or B-plate in the vertical direction, that is transverse to the laying plane, the respective projections are guided past each other, so that the projections of a plate in the associated A or B undercut of the other plate reach. This happens simultaneously for both projections or undercuts, since the mutually facing plate sides are coordinated with each other in this regard. By subsequently moving the plates in In the longitudinal direction of their adjacent sides, the A-projections with the B-projections are at least partially, but preferably completely, brought into coincidence with each other. This obstructs the initial vertical displacement of the adjacent plates initially performed for bonding. Without canceling the overlap between the A and B protrusions, the plates can no longer shift in the vertical direction, ie perpendicular to the mounting position. The plates are locked together. In this case, the A and / or B undercuts can be designed such that the connection between the A-projections and the A-undercut with the B-projections and / or the connection between the B-projections and the B-undercut with the A-projections in the region of the overlap is at least partially positive fit.

Da einander benachbarte bzw. sich überdeckende Vorsprünge eine Verlagerung nur in eine Richtung quer zur Montagelage verhindern, ist es wichtig, dass die Verlagerung in die andere Richtung durch die entsprechend orientierten Verriegelungsleisten verhindert wird. Zudem muss gewährleistet sein, dass die Platten sich nicht in der Montagelage gegeneinander verschieben können. Hierzu dient eine an der A-Verriegelungsleiste angeordnete A-Sperrnut zur Aufnahme einer B-Sperrleiste der benachbarten B- Verriegelungsleiste. Ebenso weist die B-Verriegelungsleiste eine B-Sperrnut für eine A-Sperrleiste einer benachbarten A-Verriegelungsleiste auf. Die A- und B-Sperrnuten sowie die A- und B-Sperrleisten erstrecken sich in Längsrichtung der benachbarten Plattenseiten. Parallel zum Verzahnen und Verlagern der Vorsprünge in die jeweiligen Verriegelungsnuten gelangen jeweils die A- und B-Sperrleiste mit der zugehörigen Spermut in Eingriff. Somit sind einander benachbarte Platten auch gegen ein seitliches Verschieben gesperrt.Since adjacent protrusions prevent displacement only in one direction transverse to the mounting position, it is important that the displacement in the other direction be prevented by the correspondingly oriented locking strips. In addition, it must be ensured that the plates can not move in the mounting position against each other. For this purpose, a arranged on the A-locking strip A-locking groove for receiving a B-locking bar of the adjacent B-locking bar. Likewise, the B-lock bar has a B-lock groove for an A-lock bar of an adjacent A-lock bar. The A and B locking grooves and the A and B locking strips extend in the longitudinal direction of the adjacent plate sides. Parallel to the gear teeth and displacing the projections into the respective locking grooves, the A and B locking strips engage with the associated locking nut. Thus, adjacent plates are also locked against lateral displacement.

Für eine spielfreie Verlegung entsprechen die Breite der A-Sperrleiste der Breite der B-Sperrnut sowie die Breite der B-Sperrleiste der Breite der A-Sperrnut. Dadurch wird ein formschlüssiges und spielfreies Ineinandergreifen der A- und B-Verriegelungsleisten gewährleistet. Die A- und B-Sperrleisten sowie die A- und B-Sperrnuten können verschiedene, beispielsweise rechteckige oder zumindest teilweise abgerundete, Querschnitte aufweisen. Wichtig ist hierbei der spielfreie Eingriff der A- und B-Sperrleiste in die dazugehörige A- und B-Spermut.For a clearance-free installation, the width of the A-locking bar corresponds to the width of the B-locking groove and the width of the B-blocking bar to the width of the A-locking groove. This ensures a positive and play-free engagement of the A and B locking strips. The A and B locking bars and the A and B locking grooves may have different, for example rectangular or at least partially rounded, cross-sections. Important here is the backlash-free engagement of the A and B locking bar in the associated A and B Spermut.

In alternativer Ausführungsform ist vorgesehen, dass die A-Hinterschneidung nicht nur als Hinterschneidung in Vertikalrichtung, d.h. senkrecht zur Verlegeebene, sondern auch als Hinterschneidung in der Verlegeebene dient. Mit anderen Worten können die in die A-Hinterschneidung eingreifenden B-Vorsprünge in der Verriegelungsposition weder in Horizontalrichtung, d.h. der Richtung der Verlegeebene, noch in Vertikalrichtung aus den A-Hinterschneidungen herausgezogen werden. Dies setzt voraus, dass die Mündung der A-Hinterschneidung schmaler ist als der tiefer liegende Bereich der A-Hinterschneidung, der entsprechend erweitert sein muss. Die Art und Weise, wie sich die A-Hinterschneidung von der Mündung in Richtung zum Tiefsten der A-Hinterschneidung vergrößert, ist hierbei beliebig. Vorteilhaft ist jedoch, wenn eine der sich gegenüberliegenden Seitenflächen der A-Hinterschneidung gegenüber der anderen Seitenfläche schräg gestellt ist, so dass sich ein trapezförmiger Querschnitt der A-Hinterschneidung ergibt. Hierbei ist es unerheblich, ob die obere oder die untere Seitenfläche oder auch beide Seitenflächen geneigt sind.In an alternative embodiment, it is provided that the A undercut is not limited to being an undercut in the vertical direction, i. perpendicular to the laying level, but also serves as an undercut in the laying plane. In other words, in the locking position, the B-projections engaging in the A-undercut can not be moved in the horizontal direction, i. the direction of the laying plane, are still pulled out of the A-undercuts in the vertical direction. This implies that the mouth of the A-undercut is narrower than the deeper region of the A-undercut, which must be extended accordingly. The way in which the A-undercut increases from the mouth toward the bottom of the A-undercut is arbitrary. It is advantageous, however, if one of the opposite side surfaces of the A-undercut is inclined relative to the other side surface, so that there is a trapezoidal cross-section of the A-undercut. It is irrelevant whether the upper or the lower side surface or both side surfaces are inclined.

Eine Neigung der unteren Seitenflächen gegenüber der Horizontalen bzw. gegenüber der Verlegeebene hat den Vorteil, dass die Seitenfläche zur Stirnseite einer A-Verriegelungsleiste fortgesetzt werden kann, so dass auf eine separat ausgebildete A-Sperrnut komplett verzichtet werden kann. Die Funktion der ineinander greifenden Sperrleisten, die eine Zugsicherung in der Verlegeebene gewährleisten sollen, wird hierbei durch die Schrägstellung der wenigstens einen Seitenfläche ermöglicht. Selbstverständlich ist im Rahmen der Erfindung nicht ausgeschlossen, dass zusätzlich zu der schräg gestellten Seitenfläche der Hinterschneidung weiterhin Sperrleisten und Sperrnuten beliebiger Konfiguration vorgesehen sind, um eine zusätzliche Zugsicherung in der Verlegeebene zu schaffen.An inclination of the lower side surfaces relative to the horizontal or relative to the laying plane has the advantage that the side surface can be continued to the end of an A-locking bar, so that can be completely dispensed with a separately formed A-locking groove. The function of the interlocking locking strips, which are to ensure a train protection in the laying plane, this is made possible by the inclination of the at least one side surface. Of course, in the context of the invention is not excluded that in addition to the inclined side surface of the undercut locking bars and locking grooves of any configuration are provided to provide additional train protection in the laying plane.

Die Verbindung zweier Platten kann durch ein nochmaliges, gewissermaßen umgekehrtes Verschieben der Vorsprünge wieder gelöst werden, indem die Vorsprünge um einen halben Vorsprungsabstand verschoben werden. Dadurch gelangen die B-Vorsprünge zwischen zwei benachbarte A-Vorsprünge und können durch eine vertikale Bewegung aus der A-Verriegelungsnut herausgehoben werden. Die A- und B-Platten sind wieder voneinander getrennt.The connection of two plates can be solved by a repeated, somewhat reverse displacement of the projections again by the projections are shifted by half a projection distance. As a result, the B-projections between two adjacent A-projections and can be lifted by a vertical movement of the A-locking groove. The A and B plates are separated again.

Die bajonettverschlussartige Verbindung zweier Platten ermöglicht mit wenigen, leichten Handgriffen eine verdreh- und verkippsichere Verbindung zwischen benachbarten Platten. Ein zusätzliches Bauteil oder Werkzeug ist zum Verbinden der Platten nicht erforderlich.The bayonet-type connection of two plates allows a twist-and tilt-proof connection between adjacent plates with a few, light handles. An additional component or tool is not required for connecting the plates.

Figur 1 zeigt eine Platte A eines Fußbodenbelags mit einer den Fußbodenbelag bildenden Sichtseite 1 ohne Berücksichtigung der Ausgestaltung der Kopfseiten 2A. An einer Längsseite der Platte A ist eine A-Verriegelungsleiste 3 vorgesehen. A-Vorsprünge 4 erstrecken sich in einer tiefer als die Sichtseite 1 liegenden und parallel zur dieser verlaufenden Ebene und sind in Richtung dieser Ebene wellenförmig ausgebildet. Die A-Vorsprünge 4 weisen zu einer benachbarten Platte B und sind in gleichen Abständen C1 zueinander angeordnet. Die A-Vorsprünge befinden sich oberhalb der A-Verriegelungsleiste 3. FIG. 1 shows a plate A of a floor covering with a floor covering forming the visible side 1 without consideration of the configuration of the head sides 2A. On one longitudinal side of the plate A, an A-locking bar 3 is provided. A-projections 4 extend in a deeper than the visible side 1 lying and parallel to this plane extending and are wave-shaped in the direction of this plane. The A-projections 4 face to an adjacent plate B and are arranged at equal intervals C1 to each other. The A-projections are located above the A-locking bar. 3

Die A-Vorsprünge 4 begrenzen eine zur benachbarten Platte B (Figur 2) weisende horizontal ausgerichtete A-Hinterschneidung 5 zur Sichtseite 1 des Fußbodenbelags. Die A-Hinterschneidung 5 ist im Querschnitt U-förmig ausgestaltet und weist eine gleich bleibende Tiefe auf. Die A-Hinterschneidung 5 wird nach unten von der A-Verriegelungsleiste 3 begrenzt.The A-projections 4 delimit one to the adjacent plate B (FIG. FIG. 2 ) facing horizontally oriented A-undercut 5 to the visible side 1 of the floor covering. The A-undercut 5 is designed in cross-section U-shaped and has a constant depth. The A-undercut 5 is bounded below by the A-locking bar 3.

Zwischen einer zu einer benachbarten Platte weisenden Stirnseite 6 der A-Verriegelungsleiste 3 und der A-Hinterschneidung 5 ist eine zur Sichtseite 1 des Fußbodenbelags offene und in Längsrichtung L der A-Verriegelungsleiste 3 verlaufende A-Sperrnut 7 einer Breite D1 vorhanden. Die A-Sperrnut 7 wird durch eine vorgelagerte A-Sperrleiste 8 mit einer Breite D2 begrenzt. Figur 2 zeigt eine Platte B des Fußbodenbelags in Blickrichtung auf ihre zum Boden weisende Unterseite 9. An einer Längsseite der Platte B ist eine B-Verriegelungsleiste 10 vorgesehen, an deren Stirnseiten 11 B-Vorsprünge 12 angeordnet sind. Die B-Vorsprünge 12 erstrecken sich in einer Ebene parallel zur Unterseite 9 der Platte B und sind in dieser Ebene wellenförmig ausgebildet. Sie weisen zu einer A-Verriegelungsleiste 3 einer benachbarten Platte A und sind in Längsrichtung L der B-Verriegelungsleiste 10 in gleich bleibenden Abständen C2 angeordnet.Between a pointing to an adjacent plate end face 6 of the A-locking bar 3 and the A-undercut 5 is a visible side of the 1 Flooring open and extending in the longitudinal direction L of the A-locking bar 3 A-locking groove 7 a width D1 available. The A-locking groove 7 is limited by an upstream A-locking bar 8 with a width D2. FIG. 2 shows a plate B of the floor covering in the direction of its bottom-facing bottom 9. On one longitudinal side of the plate B, a B-locking strip 10 is provided at the end faces 11 B-projections 12 are arranged. The B-projections 12 extend in a plane parallel to the underside 9 of the plate B and are formed wave-shaped in this plane. They point to an A-locking strip 3 of an adjacent plate A and are arranged in the longitudinal direction L of the B-locking strip 10 at equal intervals C2.

Die B-Vorsprünge 12 bilden eine bodenseitige Begrenzung einer zur benachbarten Platte A weisenden und sich in Längsrichtung L der B-Verriegelungsleiste 10 erstreckenden B-Hinterschneidung 13. Die B-Hinterschneidung 13 ist im Querschnitt U-förmig ausgestaltet und verläuft durchgängig in Längsrichtung L der B-Verriegelungsleiste 10. Dabei ist die B-Hinterschneidung 13 zu den Kopfseiten 2B dieser Platte B hin offen ausgestaltet. Den B-Vorsprüngen 12 gegenüber liegend wird die B-Hinterschneidung 13 durch einen Steg 14 begrenzt, der sich bis zur Sichtseite 15 der Platte B erstreckt. Zur Unterseite 9 weisend ist eine B-Sperrnut 16 der Breite D3 an der Verriegelungsleiste 10 angeordnet. Diese erstreckt sich in Längsrichtung L der Platte B. Dabei begrenzt eine B-Sperrleiste 17 der Breite D4 die B-Sperrnut 16.The B-projections 12 form a bottom boundary of an adjacent plate A facing and extending in the longitudinal direction L of the B-locking bar 10 B-undercut 13. The B-undercut 13 is configured in cross-section U-shaped and runs continuously in the longitudinal direction L of B-locking bar 10. In this case, the B-undercut 13 is configured open to the head sides 2B of this plate B. The B-projections 12 opposite the B-undercut 13 is limited by a web 14 which extends to the visible side 15 of the plate B. Pointing to the underside 9, a B-locking groove 16 of width D3 is arranged on the locking strip 10. This extends in the longitudinal direction L of the plate B. In this case limits a B-locking bar 17 of the width D4, the B-locking groove 16th

Die Abstände C1 zwischen den A-Vorsprüngen 4 sind gleich den Abständen C2 zwischen den B-Vorsprüngen 12.The distances C1 between the A-projections 4 are equal to the distances C2 between the B-projections 12th

Für eine leichtere Verzahnung der A- und B-Vorsprünge 4, 12 sind die B-Vorsprünge mit Fasen 18 versehen.For a lighter toothing of the A and B projections 4, 12, the B-projections are provided with chamfers 18.

In einer weiteren Ausführungsform der A- und B-Verriegelungsleisten (Figur 4 kann eine Seitenfläche 19a der A-Hinterschneidung 5a um einen Winkel W gegenüber der Verlegeebene geneigt angeordnet sein. Dieser Winkel W liegt vorzugsweise zwischen 0 bis 15°. Durch eine hierzu komplementär ausgestaltete Ausführung der B-Verriegelungsleiste 10a wird neben einer Sicherung gegen eine Verlagerung senkrecht zur Montagelage auch eine Sicherung gegen eine Verlagerung in eine Richtung der Montagelage erzielt.In a further embodiment of the A and B locking strips ( FIG. 4 For example, a side surface 19a of the A undercut 5a may be inclined at an angle W with respect to the laying plane. This angle W is preferably between 0 to 15 °. By a complementarily designed this embodiment of the B-locking bar 10 a is in addition to a backup against a shift perpendicular to the mounting position also achieved a backup against a shift in one direction of the mounting position.

Weitere Ausführungsformen der A- und B-Verriegelungsleisten 3b, 3c, 10b, 10c sind in den Figuren 5 und 6 dargestellt. Hierbei entfallen quasi die A- und B-Sperrnuten und -leisten und die A-Hinterschneidung 5b wird beispielsweise durch eine gegenüber der Verlegeebene geneigte Seitenfläche 19b begrenzt. Diese Seitenfläche erstreckt sich bis zur Stirnseite 6b und steigt in Richtung der Stirnseite 6b an. Die B-Verriegelungsleiste 10b ist hierzu komplementär ausgestaltet. Werden die B-Vorsprünge 12d in der A-Hinterschneidung 5b eingesteckt (Figur 5), entsteht durch die Neigung der Seitenfläche 19b eine Hinterschneidung zwischen der A- und B-Verriegelungsleiste 3b, 10b und zwar derart, dass die Platten A, B auch gegenüber einer horizontalen Verschiebung gesichert sind.Further embodiments of the A and B locking strips 3b, 3c, 10b, 10c are in the FIGS. 5 and 6 shown. This eliminates virtually the A and B locking grooves and strips and the A-undercut 5b is limited for example by a relative to the laying plane inclined side surface 19b. This side surface extends to the end face 6b and rises in the direction of the end face 6b. The B-locking strip 10b is designed to be complementary. Are the B-projections 12d inserted in the A-undercut 5b ( FIG. 5 ), caused by the inclination of the side surface 19b, an undercut between the A and B-locking bar 3b, 10b in such a way that the plates A, B are also secured against a horizontal displacement.

In Figur 6 ist die Seitenfläche 19c wellenförmig ausgestaltet und erstreckt sich bis zur Stirnseite 6c der A-Verriegelungsleiste 3c. Die komplementär hierzu ausgestaltete B-Verriegelungsleiste 10c ist ebenfalls wellenförmig ausgestaltet, so dass beim Ineinandergreifen der B-Vorsprünge 12e in die A-Hinterschneidung 5c zwischen den A- und B-Verriegelungsleisten 3c, 10c durch die Wellenform einen Hinterschneidung entsteht, welche beide Platten A, B gegen eine Verschiebung in der Verlegeebene sichert.In FIG. 6 is the side surface 19c wave-shaped and extends to the end face 6c of the A-locking bar 3c. The complementarily configured B-locking bar 10c is also wave-shaped, so that when engaging the B-projections 12e in the A-undercut 5c between the A and B locking strips 3c, 10c by the waveform creates an undercut, which both plates A , B secures against displacement in the laying plane.

Bei den Ausführungsformen der Figuren 5 und 6 entfällt eine Sperrnut, wie sie zum Beispiel in Figur 4 vorgesehen ist. Dadurch können die miteinander zu verriegelnden Platten durch eine Montagebewegung in Überdeckung gebracht werden, die im Wesentlichen der korrespondierenden Seitenfläche der Hinterschneidungen entspricht. Am Besten ist dies in Figur 5 zu erkennen, bei welcher die Verriegelungsleiste 3b gewissermaßen rampenförmig konfiguriert ist. Die Neigung dieser Rampe bestimmt die mögliche Richtung der Montagebewegung. Die Montagebewegung kann somit bei den Ausführungsformen der Figuren 5 und 6 etwas anders ausgeführt werden, als bei den vorher beschriebenen Varianten, bei denen ein ausschließlich in Vertikalrichtung orientiertes Absenken einer Platte notwendig ist.In the embodiments of the FIGS. 5 and 6 eliminates a locking groove, as for example in FIG. 4 is provided. As a result, the plates to be locked together can be brought into coincidence by an assembly movement, which substantially corresponds to the corresponding side surface of the undercuts. This is best in FIG. 5 can be seen, in which the locking bar 3b is configured in a sense ramp-shaped. The inclination of this ramp determines the possible direction of the assembly movement. The assembly movement can thus in the embodiments of FIGS. 5 and 6 be carried out somewhat differently than in the previously described variants in which an exclusively vertically oriented lowering of a plate is necessary.

Um die Platte A und die benachbarte Platte B zu verbinden, wird die A-Verriegelungsleiste 3 mit der B-Verriegelungsleiste 10 in rastenden Eingriff gebracht (Figur 7).To connect the plate A and the adjacent plate B, the A-locking bar 3 is brought into latching engagement with the B-locking bar 10 ( FIG. 7 ).

Hierzu werden die A-Vorsprünge 4 mit den B-Vorsprüngen 12 zweier gegenüber liegender A- und B-Verriegelungsleisten 3, 10 miteinander verzahnt, indem die A- und B-Verriegelungsleisten 3, 10 um einen Vorsprung versetzt zueinander angeordnet werden (Pfeil I). Dabei wird aus Blickrichtung von oben jeweils ein A-Vorsprung 4 zwischen zwei B-Vorsprüngen 12 angeordnet. In dieser Position ist die Platte B allerdings noch in horizontaler und vertikaler Richtung zur Platte A versetzt. Eine auf der A-Sperrleiste 8 oder zur benachbarten B-Verriegelungsleiste 10 weisend angeordnete Markierung M erleichtert das Ausrichten der Platten A und B zueinander.For this purpose, the A-projections 4 are interlocked with the B-projections 12 of two opposite A and B locking strips 3, 10 by the A and B locking strips 3, 10 are offset by a projection to each other (arrow I) , In this case, an A-projection 4 between two B-projections 12 is arranged from above as viewed from above. In this position, however, the plate B is still offset in the horizontal and vertical direction to the plate A. A marked on the A-locking bar 8 or the adjacent B-locking bar 10 marking M facilitates the alignment of the plates A and B to each other.

Bei einem vertikalen Verlagern bzw. Absenken (Pfeil II) der B-Platte zum Boden hin, gelangen die B-Vorsprünge 12 und die A-Vorsprünge 4 zunächst in verzahnenden Eingriff und werden dann aneinander vorbei bewegt. Gleichzeitig gelangen die B-Vorsprünge 12 in die A-Hinterschneidung 5 und die A-Vorsprünge 4 in die B-Hinterschneidung 13. Ebenfalls gleichzeitig hierzu gelangen die A-Sperrleiste 8 mit der B-Sperrnut 16 und die B-Sperrleiste 17 mit der A-Sperrnut 7 in Eingriff. Durch diesen gegenseitigen Eingriff sind die Platten A, B ineinander in ihrer Längsrichtung L geführt. Die Platte B ist jetzt nur noch in Längsrichtung L, nicht aber mehr in Hochrichtung zur Platte A versetzt angeordnet.In the case of a vertical displacement or lowering (arrow II) of the B-plate towards the bottom, the B-projections 12 and the A-projections 4 first engage in a meshing manner and are then moved past each other. At the same time reach the B-projections 12 in the A-undercut 5 and the A-projections 4 in the B-undercut 13. Also at the same time get the A-locking bar 8 with the B-locking groove 16 and the B-locking bar 17 with the A. -Sperrnut 7 engaged. By this mutual engagement, the plates A, B are guided into each other in their longitudinal direction L. The plate B is now only offset in the longitudinal direction L, but not offset in the vertical direction to the plate A.

Eine Verschiebung (Pfeil III) in Längsrichtung L der B-Verriegelungsleiste 10 relativ zur A-Verriegelungsleiste 3 bringt die A-Vorsprünge 4 mit den B-Vorsprüngen 12 übereinander in Deckung. Dadurch kommen die A- und B-Verriegelungsleisten 3, 10 miteinander in Eingriff und ein Anheben der Platte B gegenüber der Platte A ist nicht mehr möglich, ebenso wenig ein seitliches Verschieben der Platten A, B gegeneinander. In dieser Verriegelungsposition sind die senkrecht zu den verriegelten Seiten der Platten aneinander ausgerichtet.A displacement (arrow III) in the longitudinal direction L of the B-locking bar 10 relative to the A-locking bar 3 brings the A-projections 4 with the B-projections 12 one above the other in coincidence. As a result, the A and B locking strips 3, 10 engage each other and lifting the plate B relative to the plate A is no longer possible, nor a lateral displacement of the plates A, B against each other. In this locking position, the perpendicular to the locked sides of the plates are aligned with each other.

Die Breite D2 der A-Sperrleiste 8 entspricht der Breite D3 der B-Sperrnut 16, so wie die Breite D4 der B-Sperrleiste 17 der Breite D1 der A-Sperrnut 7 entspricht. Dadurch wird ein formschlüssiges Ineinandergreifen der A- und B-Verriegelungsleisten 3, 10 gewährleistet.The width D2 of the A-locking bar 8 corresponds to the width D3 of the B-locking groove 16, as the width D4 of the B-locking bar 17 corresponds to the width D1 of the A-locking groove 7. Thereby a positive engagement of the A and B locking strips 3, 10 is ensured.

Die Platten A, B sind formschlüssig miteinander verbunden. Vorteilhaft hierbei ist, dass die Verbindung zwischen den Platten A, B durch nur drei einfache Relativbewegungen möglich ist: dem Verzahnen I der A- und B-Vorsprünge, dem vertikalen, zur Platte A justierten Absenken II der Platte B und dem relativen Verschieben III der Platte B zur Platte A in Längsrichtung L.The plates A, B are positively connected with each other. The advantage here is that the connection between the plates A, B by only three simple relative movements is possible: the teeth I of the A and B projections, the vertical, adjusted to the plate A lowering II of the plate B and the relative displacement III of Plate B to plate A in the longitudinal direction L.

Ein weiterer Vorteil ist, dass die Verbindung zwischen den Platten A, B zerstörungsfrei reversibel ist. Auch werden keine weiteren Bauteile benötigt, um die Verbindung zu realisieren.Another advantage is that the connection between the plates A, B is non-destructive reversible. Also, no other components are needed to realize the connection.
