Abstract

The invention relates to a panel (1, 2) of a floor system, particularly a laminate floor, comprising a first lateral edge (3) and a second lateral edge (4) which is arranged opposite the first lateral edge (3). Said lateral edges (3, 4) can be interlocked with corresponding lateral edges (4, 3) of additional panels (1, 2) and can be made to engage with each other essentially by performing a vertical movement. The aim of the invention is to interlock panels in a simpler and safer manner. Said aim is achieved by providing the first lateral edge (3) with a fitting spring (6) which extends from the upper surface (5) towards the bottom, a locking lip (7) that extends from the upper surface (5) towards the bottom, a locking groove (8) that is located between the fitting spring (6) and the locking lip (7), and an elasticity groove (9) that is disposed on the side of the locking lip (7), which lies opposite the locking groove (8), while providing the second lateral edge (4) with a locking spring (11) which extends from the lower surface (10) towards the top and a fitting groove (12) that is adjacent to the locking spring (11). The fitting spring (6) engages with the fitting groove (12) in the interlocked state, the distal end (13) of the fitting spring (6) resting against the bottom of the fitting groove (12), while the locking spring (11) engages with the locking groove (8) and the locking lip (7).

Description

Paneel eines Fußbodensystems, insbesondere eines Panel of a floor system, especially one
Laminatfußbodenslaminate flooring
Die Erfindung betrifft ein Paneel eines Fußbodensystems, das mechanisch mit anderen Paneelen verriegelt werden kann, mit einer ersten Seitenkante und mit einer zweiten Seitenkante, die der ersten Seitenkante gegenüberliegend angeordnet ist, wobei die Seitenkanten mit korrespondierenden Seitenkanten weiterer Paneelen verriegelbar sind.The invention relates to a panel of a floor system that can be mechanically locked with other panels, with a first side edge and with a second side edge that is arranged opposite the first side edge, the side edges being lockable with corresponding side edges of further panels.
Insbesondere betrifft die Erfindung ein Paneel eines Laminatfußbodensystems, bei dem die Paneelen aus einem Kern aus einer HDF- oder MDF-Platte oder aus einer Spanplatte bestehen, die mit einer oberen Laminatbeschichtung versehen sind.In particular, the invention relates to a panel of a laminate flooring system, in which the panels consist of a core made of an HDF or MDF board or a chipboard, which are provided with an upper laminate coating.
Aus dem Stand der Technik der WO 01/66876 sowie der WO 01/48331 sind Paneelen bekannt, bei denen die Nut-Feder- Verbindung und eine Verriegelungslippe und eine Verriegelungsfeder für die horizontale Verriegelung einstückig aus dem Material des Paneels hergestellt sind. Dazu ist die Verriegelungslippe an der Seitenkante mit der Feder der Nut-Feder-Verbindung und die Verriegelungsfeder an der Seitenkante der Nut der Nut-Feder-Verbindung ausgebildet. Somit stellt also die Verriegelungsfeder gleichzeitig auch die untere Lippe der Nut dar, weist also eine doppelte Funktion auf.Panels are known from the prior art of WO 01/66876 and WO 01/48331, in which the tongue and groove connection and a locking lip and a locking spring for horizontal locking are made in one piece from the material of the panel. For this purpose, the locking lip is formed on the side edge with the tongue of the tongue and groove connection and the locking spring on the side edge of the groove of the tongue and groove connection. Thus, the locking spring also represents the lower lip of the groove, and therefore has a double function.
Die zuvor erläuterten Paneelen weisen den Nachteil auf, dass das Verlegen einer Mehrzahl von Paneelen zu einem Fußboden erschwert ist und in der Regel nur unter Einsatz von Werkzeugen erfolgen kann.The previously explained panels have the disadvantage that the laying of a plurality of panels into one Floor is difficult and can usually only be done using tools.
Aus der WO 01/88306 AI und der WO 01/02670 sind weitere Ausgestaltungen eines Paneelprofils zu entnehmen, bei dem die Verbindungselemente mit einer senkrechten Bewegung miteinander in Verbindung gebracht werden. Dazu ist im wesentlichen eine Nut-Feder-Verbindung vorgesehen, die mit in vertikaler Richtung wirkenden Rastelementen versehen ist. Da jedoch bei diesen Ausführungsformen die horizontale und vertikale Verriegelungen mit denselben Bauelementen realisiert ist, kann es bei einer während des Verrastens auftretenden Beschädigung der vertikal wirkenden Rastelemente nachfolgend zu einer Schwächung auch der horizontalen Verriegelung kommen.WO 01/88306 AI and WO 01/02670 show further configurations of a panel profile in which the connecting elements are brought into connection with one another with a vertical movement. For this purpose, essentially a tongue and groove connection is provided, which is provided with latching elements acting in the vertical direction. However, since in these embodiments the horizontal and vertical interlocks are realized with the same components, if the vertically acting catch elements are damaged during the interlocking, the horizontal interlock may subsequently also be weakened.
Der Erfindung liegt daher das technische Problem zugrunde, ein Paneel anzugeben, das einfach und weitgehend ohne Einsatz von Werkzeugen mit anderen Paneelen verbunden werden kann und gleichzeitig eine große Stabilität der miteinander verbundenen Paneelen gewährleistet.The invention is therefore based on the technical problem of specifying a panel which can be easily and largely connected to other panels without the use of tools and at the same time ensures great stability of the interconnected panels.
Das zuvor aufgezeigte technische Problem wird erfindungsgemäß durch ein Paneel mit den Merkmalen des Anspruches 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angeführt.The technical problem indicated above is solved according to the invention by a panel with the features of claim 1. Further advantageous embodiments of the invention are set out in the subclaims.
Erfindungsgemäß ist erkannt worden, das eingangs erläuterte Paneel folgendermaßen auszugestalten. Die Seitenkanten können im wesentlichen durch eine senkrecht verlaufende Bewegung miteinander in Eingriff gebracht werden. Dazu sind die beiden Seitenkanten mit zueinander korrespondierenden Profilen versehen. Die erste Seitenkante weist von der Oberseite nach unten weg gerichtete Passfeder, eine von der Oberseite nach unten gerichteten Verriegelungslippe, eine zwischen der Passfeder und der Verriegelungslippe angeordnete Verriegelungsnut und eine auf der von der Verriegelungsnut abgewandten Seite der Verriegelungsfeder angeordneten Elastizitätsnut auf.According to the invention, it has been recognized that the panel explained at the outset is configured as follows. The side edges can be brought into engagement with one another essentially by a vertical movement. For this purpose, the two side edges are provided with corresponding profiles. The first side edge has a feather key directed downward from the top, a locking lip directed downward from the top, a locking groove arranged between the feather key and the locking lip and an elastic groove arranged on the side of the locking spring facing away from the locking groove.
Die zweite Seitenkante weist dagegen eine von der Unterseite nach oben gerichteten Verriegelungsfeder und eine an die Verriegelungsfeder angrenzende Passnut auf.The second side edge, on the other hand, has a locking spring directed upwards from the underside and a fitting groove adjoining the locking spring.
Im verriegelten Zustand, also nachdem die beiden Seitenkanten mit einer im wesentlichen vertikal verlaufenden Bewegung miteinander in Eingriff gebracht worden sind, steht die Passfeder mit der Passnut in Eingriff, wobei das distale Ende der Passfeder am Nutgrund der Passnut anliegt. Des weiteren steht die Verriegelungsfeder mit der Verriegelungsnut und der Verriegelungslippe in Eingriff.In the locked state, that is to say after the two side edges have been brought into engagement with one another with a substantially vertical movement, the feather key engages with the feathering groove, the distal end of the feather key resting against the groove base of the feathering groove. Furthermore, the locking spring is in engagement with the locking groove and the locking lip.
Somit wird mit voneinander getrennten Profilelementen die horizontale Verriegelung und die vertikale Verriegelung erreicht . Denn die Passfeder und die Verriegelungslippe stellen voneinander getrennte Bauelemente dar. Die Verriegelungslippe ist das Bauteil, das während des Verriegelungsschrittes für eine vertikale Verriegelung zumindest teilweise verbogen und somit einer mechanischen Belastung ausgesetzt wird. Die Passfeder wiederum wird ohne ein Verbiegen in die Passnut eingeführt und gewährleistet eine exakte horizontale Verriegelung.The horizontal locking and the vertical locking are thus achieved with separate profile elements. This is because the feather key and the locking lip are separate components. The locking lip is the component that is at least partially bent during the locking step for a vertical locking and is therefore exposed to a mechanical load. The feather key, in turn, is inserted into the feather groove without bending and ensures exact horizontal locking.
Das zuvor erläuterte Profil ermöglicht ein Verriegeln der beiden Seitenkanten miteinander durch eine im wesentlichen vertikale Bewegung. Dadurch kann jedes neu zu verlegendes Paneel mit bereits verlegten Paneelen in Eingriff gebracht werden, indem das neue Paneel mit den entsprechenden Seitenkanten oberhalb der Seitenkanten der bereits verlegten Paneelen angeordnet wird. Danach wird dieses durch einen von oben ausgeübten Druck yerriegelt .The profile explained above enables the two side edges to be locked together by an essentially vertical movement. This means that every new one can be relocated Panel can be brought into engagement with panels that have already been installed by arranging the new panel with the corresponding side edges above the side edges of the already installed panels. Then this is locked by a pressure exerted from above.
Für das Erreichen der zuvor genannten vertikalen und horizontalen Verriegelungen weist in bevorzugter Weise die Passfeder eine an die Oberseite angrenzende erste Passfläche, eine innenliegend angeordnete zweite Passfläche und eine untere dritte Passfläche auf. Die Verriegelungslippe weist eine schräg zur Oberseite verlaufende erste Verriegelungsfläche auf. Zusätzlich ist eine an die Oberseite angrenzende vierte Passfläche vorgesehen. Die Verriegelungsfeder wiederum weist eine schräg zur Unterseite verlaufende zweite Verriegelungsfläche und eine fünfte Passfläche auf . Schließlich bildet der Nutgrund der Passnut eine sechste Passfläche. Im verriegelten Zustand liegt die erste Passfläche an der vierten Passfläche, die zweite Passfläche an der fünften Passfläche, ' die dritte Passfläche an der sechsten Passfläche sowie die erste Verriegelungsfläche an der zweiten Verriegelungsfläche an. Aus dem Zusammenwirken der Passflächenpaare und des Verriegelungsflächenpaares ergibt sich eine stabile vertikale und horizontale Verriegelung. Dabei bewirken die Passflächenpaare aus erster und vierter sowie aus zweiter und fünfter Passfläche die horizontale Verriegelung und das Passflächenpaar aus der dritter und sechster Passfläche sowie die beiden Verriegelungsflächen bewirken die vertikale Verriegelung.To achieve the aforementioned vertical and horizontal locks, the feather key preferably has a first mating surface adjacent to the upper side, an internally arranged second mating surface and a lower third mating surface. The locking lip has a first locking surface that runs obliquely to the upper side. In addition, a fourth mating surface adjacent to the top is provided. The locking spring in turn has a second locking surface that runs obliquely to the underside and a fifth fitting surface. Finally, the groove base of the fitting groove forms a sixth fitting surface. In the locked state, the first fitting surface rests on the fourth fitting surface, the second mating surface on the fifth fitting surface, 'the third mating surface on the sixth fitting surface and the first locking surface on the second locking surface. The interaction of the mating surface pairs and the locking surface pair results in a stable vertical and horizontal locking. The pairs of mating surfaces from the first and fourth as well as from the second and fifth mating surfaces effect the horizontal locking and the pair of mating surfaces from the third and sixth mating surfaces as well as the two locking surfaces effect the vertical locking.
Weiterhin weist die Verriegelungsnut in bevorzugter Weise an der der Passfeder gegenüberliegenden Seite eine erste Anlagefläche auf, während die Verriegelungsfeder an der der Passnut abgewandten Seite eine zweite Anlagefläche aufweist. Im verriegelten Zustand liegt die erste Anlagefläche an der zweiten Anlagefläche an und bewirkt eine zusätzliche Stabilisierung der Verbindung.Furthermore, the locking groove preferably has a first contact surface on the side opposite the feather key, while the locking spring on the Passnut facing away from the side has a second contact surface. In the locked state, the first contact surface lies against the second contact surface and brings about an additional stabilization of the connection.
Die Elastizitätsnut dient dazu, der Verriegelungslippe eine ausreichende Elastizität zu verleihen, da die Verriegelungslippe im wesentlichen das einzige Element ist, das während des Verriegeins verbogen wird. Die Länge der Elastizitätsnut ist dabei ein einfaches Mittel zum Einstellen der Elastizität.The elastic groove serves to give the locking lip sufficient elasticity, since the locking lip is essentially the only element which is bent during the locking. The length of the elastic groove is a simple means of adjusting the elasticity.
Die Dicke der Elastizitätsnut definiert dagegen die maximale Auslenkung der Verriegelungslippe. Somit kann ein ungewolltes Auseinandergehen der Verbindung bis zu einem gewissen Ausmaß verhindert werden.The thickness of the elastic groove, however, defines the maximum deflection of the locking lip. Thus, an unwanted divergence of the connection can be prevented to a certain extent.
In weiter bevorzugter Weise weist die Elastizitätsnut zumindest teilweise ein elastisches Mittel auf. Mit diesem Mittel, das insbesondere ein PVC-Kleber sein kann, kann eine zusätzliche Kraft erzeugt werden, die das Verbiegen erschwert. Des weiteren dient dieses Mittel dazu, das Eindringen von Feutchtigkeit in den Kern des Paneels zu verhindern. Denn in einigen Fällen kann die Nut einen großen Teil der Dicke des Paneels einnehmen.In a further preferred manner, the elastic groove at least partially has an elastic means. With this agent, which can in particular be a PVC adhesive, an additional force can be generated which makes bending more difficult. Furthermore, this agent serves to prevent the penetration of hypnotism into the core of the panel. Because in some cases the groove can take up a large part of the thickness of the panel.

The side edges 3 and 4 can be brought into engagement with one another essentially by a vertical movement.
Wie die Fig. 1 und 2 zeigen, weist die erste Seitenkante 3 eine von der Oberseite 5 nach unten weg gerichtete Passfeder 6, eine von der Oberseite 5 nach unten gerichtete Verriegelungslippe 7, eine zwischen der Passfeder 6 und der Verriegelungslippe 7 angeordnete Verriegelungsnut 8 und eine auf der von der Verriegelungsnut 8 abgewandten Seite der Verriegelungslippe angeordnete ,Elastizitätsnut 9 auf.1 and 2 show, the first side edge 3 has a feather key 6 directed downwards from the top 5, a locking lip 7 directed downwards from the top 5, a locking groove 8 and arranged between the feather key 6 and the locking lip 7 an elastic groove 9 arranged on the side of the locking lip facing away from the locking groove 8.

In the locked state, the feather key 6 engages with the feather groove 12, the distal end 13 of the feather key 6 abutting the groove base 14 of the feather groove 12.

Für die Verwirklichung der horizontalen und vertikalen Verriegelung weisen bei dem dargestellten Ausführungsbeispiel die zuvor erläuterten Profilelemente die folgenden Pass- und Verriegelungsflächen auf. Diese sind insbesondere in Fig. 2 mit Bezugszeichen gekennzeichnet, während in Fig. 1 diese aus Gründen der Übersichtlichkeit nicht eingezeichnet sind.For the realization of the horizontal and vertical locking, the profile elements explained above have the following fitting and locking surfaces in the illustrated embodiment. These are identified in particular in FIG. 2 by reference numerals, while in FIG. 1 they are not shown for reasons of clarity.
Die Passfeder 6 weist eine an der Oberseite 5 angrenzende erste Passfläche 15, eine innenliegend angeordnete zweite Passfläche 16 und eine untere dritte Passfläche 13, das zuvor erwähnte distale Ende der Passfeder 6 auf.The feather key 6 has a first fitting surface 15 adjoining the upper side 5, an internally arranged second fitting surface 16 and a lower third fitting surface 13, the aforementioned distal end of the feather key 6.
Die Verriegelungslippe 7 ist versehen mit einer schräg zur Oberseite 5 verlaufende erste Verriegelungsfläche 17. Des weiteren ist an der zweiten Seitenkante 4 eine an die Oberseite 5 angrenzende vierte Passfläche 18 vorgesehen. Die Verriegelungsfeder 11 weist wiederum eine schräg zur Unterseite 10 verlaufende zweite Verriegelungsfläche 19 und eine fünfte Passfläche 20 auf. Der Nutgrund 14 der Passnut 12 bildet eine sechste Passfläche.The locking lip 7 is provided with a first locking surface 17 which runs obliquely to the upper side 5. Furthermore, a fourth fitting surface 18 adjoining the upper side 5 is provided on the second side edge 4. The locking spring 11 in turn has a second locking surface 19 which extends obliquely to the underside 10 and a fifth fitting surface 20. The groove base 14 of the fitting groove 12 forms a sixth fitting surface.
Im verriegelten Zustand liegt die erste Passfläche 15 an der vierten Passfläche 18, die zweite Passfläche 16 an der fünften Passfläche 20, die dritte Passfläche 13 an der sechsten Passfläche 14 und die erste Verriegelungsfläche 17 an der zweiten Verriegelungsfläche 19 an. Mit anderen Worten bilden das Passflächenpaar 15 und 18 und das Passflächenpaar 16 und 20 die horizontale Verriegelung, diese Passflächen im wesentlichen vertikal verlaufen. Das Passflächenpaar 13 und 14 sowie dasIn the locked state, the first mating surface 15 bears on the fourth mating surface 18, the second mating surface 16 on the fifth mating surface 20, the third mating surface 13 on the sixth mating surface 14 and the first locking surface 17 on the second locking surface 19. In other words, the pair of mating surfaces 15 and 18 and the pair of mating surfaces 16 and 20 form the horizontal locking, these mating surfaces run essentially vertically. The pair of fitting surfaces 13 and 14 and the
Verriegelungsflächenpaar 17 und 19 bilden dagegen die vertikale Verriegelung. Da die Verriegelungsflächen 17 und 19 schräg verlaufen, haben diese sogar eine Wirkung sowohl bezüglich der horizontalen als der vertikalen Verriegelung.Locking surface pair 17 and 19, however, form the vertical locking. Since the locking surfaces 17 and 19 run obliquely, they even have an effect with respect to both the horizontal and the vertical locking.
Wie die Fig. 1 und 2 weiterhin zeigen, kann die Verriegelungsnut 8 an der der Passfeder 6 gegenüberliegenden Seite eine erste Anlagefläche 21 aufweisen und kann die Verriegelungsfeder 7 an der der Passnut 12 abgewandten Seite eine zweite Anlagefläche 22 aufweisen, so dass im verriegelten Zustand der beiden Seitenkanten 3 und 4 die erste Anlagefläche 21 und zweite Anlagefläche 22 aneinander anliegen. Dieses ist an sich nicht für die Verriegelung der Profile erforderlich, führt aber zu einer Stabilisierung des gesamten Profils.1 and 2 also show, the locking groove 8 can have a first contact surface 21 on the side opposite the key 6 and the locking spring 7 can have a second contact surface 22 on the side facing away from the key groove 12, so that in the locked state the two contact edges 3 and 4 the first contact surface 21 and the second contact surface 22 abut one another. This is not in itself necessary for locking the profiles, but leads to a stabilization of the entire profile.
Fig. 3 zeigt ein weiteres Ausführungsbeispiel der vorliegenden Erfindung, wobei gleiche Bezugszeichen gleiche Bauteile und Flächen kennzeichnen. Das gezeigte Profil ist ähnlich dem in Fig. 1 dargestellten Profil, jedoch weist das in Fig. 3 gezeigte Profil weitere Merkmale auf, die allein oder in Kombination die vorliegende Erfindung weiterbilden.3 shows a further exemplary embodiment of the present invention, the same reference symbols denoting the same components and surfaces. The profile shown is similar to the profile shown in FIG. 1, however the profile shown in FIG. 3 has further features which, alone or in combination, further develop the present invention.
Im Unterschied zu den Fig. 1 und 2 sind die Anlageflächen 21 und 22 nicht vorhanden, so dass die Verriegelungsfeder nur entlang der Verriegelungsflächen 17 und 19 aneinander anliegen. Die Länge der Elastizitätsnut 9 bestimmt die Elastizität der Verriegelungslippe 7. Daher kann die Elastizität der Verriegelungslippe 7 durch die Veränderung der Position des Grundes der Elastizitätsnut 9 verändert werden. Dieses ist in Fig. durch gestrichelte Linien 23 für zwei alternative Längen dargestellt.In contrast to FIGS. 1 and 2, the contact surfaces 21 and 22 are not present, so that the locking spring only abuts against one another along the locking surfaces 17 and 19. The length of the elastic groove 9 determines the elasticity of the locking lip 7. Therefore, the elasticity of the locking lip 7 can be changed by changing the position of the base of the elastic groove 9. This is shown in FIG. 2 by broken lines 23 for two alternative lengths.
Darüber hinaus bestimmt die Dicke der Elastizitätsnut 9 die maximale Auslenkung der Verriegelungslippe 7. Denn dann, wenn die in Fig. 3 linke Seite der Verriegelungslippe 7 an der gegenüberliegenden Seite der Elastizitätsnut 9 anliegt, ist ein weiteres Verbiegen der Verriegelungslippe 7 nicht mehr möglich.In addition, the thickness of the elastic groove 9 determines the maximum deflection of the locking lip 7. Because if the left side of the locking lip 7 in FIG. 3 bears against the opposite side of the elastic groove 9, a further bending of the locking lip 7 is no longer possible.
Die Elastizitätsnut 9 kann darüber hinaus auch mit einem elastischen Mittel zumindest teilweise ausgefüllt sein. Dieses ist durch ein schwarze Füllung der Fläche der dargestellten Elastizitätsnut 9 in Fig. 3 gekennzeichnet. Gezeigt ist eine vollständige Füllung der Elastizitätsnut 9, eine abschnittsweise Füllung ist ebenso möglich.The elasticity groove 9 can also be at least partially filled with an elastic means. This is characterized by a black filling of the surface of the elastic groove 9 shown in FIG. 3. A complete filling of the elastic groove 9 is shown, a filling in sections is also possible.
In bevorzugter Weise ist das elastische Mittel ein PVC- Kleber. Es sind aber auch andere elastische natürliche oder künstliche Stoffe zum Einsatz geeignet. The elastic means is preferably a PVC adhesive. However, other elastic natural or artificial substances are also suitable for use.
