Abstract

The invention relates to a panel connection, particularly for flooring panels, having a groove (34) that is embodied at a side edge (3); a spring (32) that is embodied at a side edge (4); a depression (35) that is embodied in the groove (34) and has an interlocking surface (16); an interlocking element (33) that is embodied at the spring (32) and has an interlocking surface (27); and fitting surfaces (12, 22), which are embodied in the groove (34) and at the spring (32) and serve as abutments for the interlocking surfaces (17, 27). The properties of interlocking and orientation stability are improved in that the groove (34) has fitting surfaces (14, 15), which extend parallel to the top side (5), in the region of the groove bottom (7), and the spring (32) has fitting surfaces (24, 25), which extend parallel to the top side (9), in the region of the end surface (8), with the fitting surfaces (14, 24; 15, 25) resting against one another in the interlocked state of the connection.

Description

Die Erfindung betrifft ein Paneel, insbesondere Fußbodenpaneel, mit den Merkmalen des Oberbegriffes des Anspruches 1, das mechanisch mit weiteren Paneelen mechanisch verbunden werden kann. Derartige Paneelen werden in typischer Weise für einen Bodenbelag, beispielsweise Parkett oder Laminatfußboden, oder für Decken- und Wandverkleidungen verwendet.The invention relates to a panel, in particular a floor panel, with the features of the preamble of the claim 1, the mechanical with additional panels mechanical can be connected. Such panels are becoming more typical Way for a floor covering, for example parquet or laminate flooring, or for ceiling and wall coverings used.

In allen Fällen lassen sich die einzelnen Paneelen durch eine mechanische Verbindung, d. h. Verriegelung, zu einer flächigen Gesamtheit vereinen, so daß ein Verlegen der Paneelen ohne Klebstoffe oder zusätzliche mechanische Befestigungselemente, z. B. Schrauben oder Nägel, möglich ist. Insbesondere ergibt sich daraus der Vorteil, daß die Paneelen sich ohne ein Verleimen verlegen und somit wieder entfernen lassen können.In all cases, the individual panels can be passed through a mechanical connection, d. H. Locking, to a unite flat area, so that a relocation of the Panels without adhesives or additional mechanical fasteners, z. B. screws or nails possible is. In particular, this has the advantage that the Panels move without gluing and thus again can be removed.

Aus der JP 3-169967 A ist eine mechanische Verbindung von Fußbodenpaneelen bekannt. Die Paneelen weisen entlang einer Seitenkante eine darin ausgebildete Nut auf, die von einer oberen Lippe und einer unteren Lippe gebildet wird und sich parallel zur Seitenkante erstreckt. An der gegenüberliegenden Seitenkante des gleichen Paneels ist eine Feder ausgebildet, die sich parallel zu dieser Seitenkante erstreckt. In der Nut ist eine Vertiefung ausgebildet, die eine schräg zur Oberseite des Paneels verlaufende Verriegelungsoberfläche aufweist. An der Feder ist ein dazu korrespondierendes Verriegelungselement ausgebildet, die eine schräg zur Oberseite verlaufende Verriegelungsoberfläche aufweist. Des weiteren sind in der Nut und an der Feder im Bereich der jeweiligen Seitenkante parallel zur Oberseite verlaufende Paßflächen ausgebildet, die als Widerlager für die Verriegelungsoberflächen der Vertiefung der Nut und des Verriegelungselements der Feder dienen. Die Paßfläche der Nut überdeckt dabei in Richtung parallel zur Oberseite die Verriegelungsfläche, die gegenüberliegend in der Nut ausgebildet ist. Gleiches gilt für die Paßfläche und die Verriegelungsfläche der Feder, da die Profile der Nut und der Feder zumindest in diesen Abschnitten korrespondierend ausgebildet sind. Die Paßflächen und die Verriegelungsoberflächen liegen im verriegelten Zustand der Verbindung Paarweise aneinander an, um die oberen Flächen der Seitenkanten in Anlage aneinander zu halten. Somit wird durch das Zusammenwirken der Paßflächen und der Verriegelungsflächen erreicht, daß die aneinander anstoßenden Seitenkanten zweier Paneelen eng aneinander anliegen und eine nahezu spaltfreie Verbindung bilden.From JP 3-169967 A is a mechanical connection of floor panels known. The panels face along one side edge a groove formed therein by an upper Lip and a lower lip is formed and itself extends parallel to the side edge. On the opposite Side edge of the same panel is a spring formed, which extends parallel to this side edge. A recess is formed in the groove a locking surface sloping to the top of the panel having. There is one on the spring Corresponding locking element formed, the a locking surface sloping to the top having. Furthermore, are in the groove and on the Spring in the area of the respective side edge parallel to the Top-fitting surfaces designed as abutments for the locking surfaces of the recess serve the groove and the locking element of the spring. The mating surface of the groove covers parallel in the direction to the top the locking surface, the opposite is formed in the groove. The same applies to the Fitting surface and the locking surface of the spring, since the Profiles of the tongue and groove at least in these sections are trained accordingly. The fitting surfaces and the locking surfaces are locked State of connection in pairs to each other the upper surfaces of the side edges abut each other to keep. Thus, through the interaction of the mating surfaces and the locking surfaces achieved that the abutting side edges of two panels closely abut each other and an almost gap-free connection form.

Weiterhin ist aus dem Stand der Technik der WO 96/27721, von der die vorliegende Erfindung ausgeht, eine an den beiden Seitenkanten eines Fußbodenpaneels ausgebildete Nut-Feder-Verbindung bekannt, die mit Verriegelungsoberflächen für eine sogenannte Klickverbindung versehen ist. Im verriegelten Zustand sind den Verriegelungsoberflächen erste Paßflächen zugeordnet, die als Widerlager dienen und die Verriegelungsoberflächen im verriegelten Zustand in Anlage aneinander halten. Des weiteren sind zweite und dritte Paßflächen sowohl an der Feder als auch an der Nut ausgebildet, um eine Stabilisierung der verriegelten Verbindung zu erreichen.Furthermore, from the prior art WO 96/27721, from which the present invention is based, one on the two side edges of a floor panel trained tongue and groove connection known with locking surfaces for a so-called click connection is provided. The locking surfaces are in the locked state assigned first mating surfaces, which act as abutments serve and the locking surfaces in the locked Keep the condition together in the system. Furthermore are second and third mating surfaces on both the spring as well as formed on the groove for stabilization to reach the locked connection.

Weitere mechanische Verbindungen von Paneelen sind aus dem Stand der Technik der WO 94/26999, WO 97/47834 und WO 98/58142 bekannt.Other mechanical connections of panels are off the prior art of WO 94/26999, WO 97/47834 and WO 98/58142 known.

Den aus dem Stand der Technik bekannten mechanischen Verbindungen von Paneelen ist auf der einen Seite gemeinsam, daß sie zwar in Richtung parallel zur Oberseite der Paneelen gerichtet eine zuverlässige mechanische Verriegelung ermöglichen, daß sie jedoch nur eine geringe Steifigkeit gegenüber einem Verdrehen des Paneels um die aneinander angrenzenden Seitenkanten aufweisen. Somit können relativ einfach die Paneelen gegeneinander verschwenkt werden, so daß es zu einem Lösen der mechanischen Verbindung kommt. Dieses ist teilweise sogar im Stand der Technik für ein einfaches Verlegen der Paneelen gewünscht. Zum anderen weisen aus diesem Stand der Technik bekannte Paneelen zwar eine ausreichende Steifigkeit gegenüber dem zuvor erwähnten Verkanten und Verschwenken der Paneelen zueinander auf, jedoch besitzen diese Verbindungen keine ausreichende Festigkeit der Verriegelung der Paneelen miteinander auf.The mechanical connections known from the prior art of panels is common on one side, that they are in the direction parallel to the top of the panels directed a reliable mechanical lock allow them to have little stiffness, however against twisting the panel around each other have adjacent side edges. So you can the panels are relatively easily pivoted against each other be so that there is a loosening of the mechanical Connection is coming. This is partly even in the State of the art for easy installation of the panels desired. On the other hand point from this prior art known panels have sufficient rigidity compared to the aforementioned tilting and pivoting of the panels to each other, but they have connections insufficient locking strength of the panels together.

Der Erfindung liegt daher das technische Problem zugrunde, eine mechanische Verbindung von Paneelen mit verbesserten Verriegelungs- und Stabilitätseigenschaften anzugeben.The invention is therefore based on the technical problem a mechanical connection of panels with improved Specify locking and stability properties.

Das zuvor aufgezeigte technische Problem wird erfindungsgemäß durch ein Paneel mit den Merkmalen des Anspruches 1 gelöst. The technical problem outlined above is according to the invention through a panel with the features of claim 1 solved.

Erfindungsgemäß ist somit erkannt worden, daß zusätzlich zur Verriegelung der Feder innerhalb der Nut Paßflächen angeordnet werden, die eine Stabilisierung der Verbindung gegenüber einem Verkanten der Paneelen zueinander bewirken. Die Verriegelung wird somit durch das Paar von Verriegelungsoberflächen und dem als Widerlager dazu dienenden Paar von Paßflächen, die im Bereich der Seitenkanten angeordnet sind verwirklicht, realisiert. Ein Auseinanderbewegen der beiden Paneelen in einer Ebene parallel zu den Oberseiten und senkrecht zu den Seitenkanten wird also durch die von den Verriegelungsoberflächen erzeugten Kraft wirkungsvoll verhindert. Die Stabilisierung der beiden Paneelen im verriegelten Zustand gegenüber einem Verkanten oder Verschwenken entlang der Seitenkanten wird durch die zusätzlichen Paßflächen im Bereich des Nutgrundes bzw. der Endfläche der Feder erreicht. Somit werden die Verriegelung einerseits und die Stabilisierung der Ausrichtung der beiden Paneelen von unterschiedlichen Paßflächenpaaren gebildet.According to the invention it has thus been recognized that in addition for locking the tongue within the groove are arranged, which stabilize the connection against tilting of the panels to one another. The locking is thus through the pair of locking surfaces and the one serving as an abutment Pair of mating surfaces in the area of the side edges arranged are realized, realized. Moving apart of the two panels in a plane parallel to the tops and perpendicular to the side edges by those generated by the locking surfaces Power effectively prevented. Stabilizing the two panels in the locked state against one Tilting or swiveling along the side edges due to the additional mating surfaces in the area of the groove base or the end face of the spring. So be the locking on the one hand and the stabilization of the Alignment of the two panels from different Fitting surface pairs formed.

Ein weiterer Vorteil der erfindungsgemäßen mechanischen Verbindung von Paneelen liegt darin, daß die beiden Funktionsgruppen der Verriegelung und Ausrichtungsstabilisierung entlang einer Feder bzw. einer Nut ausgebildet sind, so daß ein gerade im Bereich von Laminatfußböden gewünschte geringe Dicke des Paneels eingehalten werden kann.Another advantage of the mechanical according to the invention Connection of panels is that the two functional groups locking and alignment stabilization are formed along a tongue or a groove, so that a desired especially in the area of laminate floors small thickness of the panel are observed can.

Erfindungsgemäß ist der Abstand zwischen der Nutverriegelungsfläche und der ersten Nutpaßfläche im Bereich der Seitenkanten größer als der Abstand zwischen der Paßflächen im Bereich des Nutgrundes bzw. der Endfläche der Feder. Dadurch wird erreicht, daß das zu Beginn des Herstellens der mechanischen Verbindung als erstes in die Nut eintretende Ende der Feder leicht von der Nut aufgenommen werden kann, da, sofern beide Paneelen auf dem gleichen Untergrund angeordnet sind, die Feder ohne mechanischen Widerstand ein vorgegebenes Stück in die Nut eindringen kann, so daß während des Zusammenfügens der Paneelen keine Schwierigkeiten auftreten, die im Stand der Technik beispielsweise durch ein Ansetzen und Verschwenken der Paneelen zueinander hervorgerufen werden. Zudem verjüngt sich die Nut von ihrer Öffnung hin bis zum Nutgrund bzw. die Feder von dem dem Paneel zugewandten Ende zur Endfläche hin, wodurch die Stabilität der Profile der Seitenkanten beider Paneelen verbessert wird.According to the invention, the distance between the groove locking surface and the first groove fitting surface in the area the side edges larger than the distance between the mating surfaces in the area of the groove base or the end surface the feather. This ensures that at the beginning of establishing the mechanical connection first in the groove entering end of the tongue slightly from the groove can be included as long as both panels are on are arranged on the same surface, the spring without mechanical resistance a predetermined piece into the groove can penetrate so that during the assembly of the Panels do not encounter any difficulties when standing the technology, for example, by attaching and pivoting of the panels to each other. In addition, the groove tapers from its opening to the Groove bottom or the tongue of the one facing the panel End towards the end face, which increases the stability of the profiles the side edges of both panels is improved.

Dazu kann eine weitere Oberfläche in der Nut ausgebildet sein, die schräg zur Oberseite verläuft und die der Vertiefung gegenüberliegend angeordneten Paßflächen miteinander verbindet. Ebenso kann auf der anderen Seite der Nut eine schräg zur Oberseite verlaufende Oberfläche ausgebildet sein, die die Verriegelungsfläche mit der im Bereich des Nutgrundes angeordnete Paßfläche verbindet.For this purpose, a further surface can be formed in the groove be that runs obliquely to the top and that of the depression oppositely arranged mating surfaces with each other combines. Likewise, on the other side of the Groove is formed on a surface that runs obliquely to the top be the locking surface with that in the area of the groove base arranged fitting surface connects.

Des weiteren ist es bevorzugt, daß die Endfläche der oberen Lippe und die Endfläche der unter Lippe, die gemeinsam die Nut bilden, im wesentlichen einer Ebene angeordnet sind. Mit anderen Worten erstrecken sich die beiden Lippen im wesentlichen gleich weit entlang der Seitenkante, so daß bei einem Herstellen der mechanischen Verbindung der Paneelen die zum Verrasten erforderliche Kraft mittels eines Schlagklotzes ausgeübt werden, wobei der Schlagklotz sowohl an der oberen als auch an der unteren Lippe anliegt und eine möglichst große Angriffsfläche erhält. Dadurch werden wirkungsvoll Beschädigungen der Seitenkanten vermieden.Furthermore, it is preferred that the end face of the upper Lip and the end face of the under lip that together form the groove, arranged essentially in one plane are. In other words, the two extend Lips essentially equidistant along the side edge, so that when establishing the mechanical connection of the panels the force required for locking be exercised by means of a tapping block, the Tapping blocks on both the top and bottom Lips up and has the largest possible contact surface. This effectively damages the side edges avoided.

Darüber hinaus ist es bevorzugt, daß die obere Lippe und die untere Lippe einstückig mit dem Paneel ausgebildet sind. Dieses ist herstellungstechnisch durch ein Herausfräsen des Profils der Nut bzw. des Profils der Feder aus der Seitenkante des Paneels möglich, woraus sich herstellungstechnisch Vorteile ergeben. Daneben ist es selbstverständlich auch möglich, die Feder, die obere und/oder untere Lippe separat herzustellen und diese mit den Paneelen zu verbinden, um die gleichen Verriegelungs- und Ausrichtungsstabilisierungseigenschaften zu erlangen.In addition, it is preferred that the upper lip and the lower lip is made in one piece with the panel are. This is manufacturing technology by milling out the profile of the groove or the profile of the tongue the side edge of the panel possible, which results in manufacturing technology Advantages. In addition, it goes without saying also possible the spring, the top and / or to produce the lower lip separately and this with the panels to connect to the same locking and Get alignment stabilization properties.

Sämtliche der nachfolgend beschriebenen Oberflächen erstrecken sich ganz oder zumindest abschnittsweise entlang einer Längs- oder Querkante der Paneelen 1 und 2, die im folgenden allgemein als Seitenkanten bezeichnet werden.Extend all of the surfaces described below all the way or at least in sections a longitudinal or transverse edge of panels 1 and 2, which in are generally referred to as side edges.

Fig. 1 zeigt ein Paneel 1, in deren äußere Kante 3 eine Nut 34 eingearbeitet ist. Dazu weist die Kante 3 eine Vielzahl von unterschiedlich zur Oberfläche 5 geneigte Oberflächen auf, die im folgenden beschrieben werden.Fig. 1 shows a panel 1, in the outer edge 3 a Groove 34 is incorporated. For this purpose, the edge 3 has a Variety of different inclined to the surface 5 Surfaces that are described below.

Eine Oberfläche 11 ist im oberen Bereich der Kante 3 benachbart zur Oberseite 5 angeordnet. Eine Oberfläche 11a verläuft unter einem flachem Winkel zur Oberfläche 11 geneigt in Richtung des Nutgrundes 7. Eine Oberfläche 12 verläuft im wesentlichen parallel zur Oberseite 5 in Richtung des Nutgrundes 7 von der Oberfläche 11a aus betrachtet. An die Oberfläche 12 schließen sich Oberflächen 13 und 14 an, wobei die Oberfläche 13 unter einem flachen Winkel nach unten weisend die Oberflächen 12 und 14 miteinander verbindet. Dabei ist die Oberfläche 14 parallel zur Oberseite 5 des Paneels 1 ausgerichtet und endet am Nutgrund 7. Somit bilden die Oberflächen 12, 13 und 14 den oberen Rand der Nut 34 in dem Paneel 1.A surface 11 is adjacent in the upper region of the edge 3 arranged to the top 5. A surface 11a is inclined at a flat angle to the surface 11 towards the bottom of the groove 7. A surface 12 runs substantially parallel to the top 5 in Direction of the groove bottom 7 viewed from the surface 11a. Surfaces close to surface 12 13 and 14, the surface 13 under a flat The surfaces 12 and 14 point downward with one another combines. The surface 14 is parallel aligned to the top 5 of the panel 1 and ends on Groove base 7. The surfaces 12, 13 and 14 thus form the upper edge of the groove 34 in the panel 1.

Die untere Oberfläche der Nut 34 wird durch Oberflächen 15, 16, 17 und 18 gebildet, die wie folgt ausgerichtet sind. Die Oberfläche 15 verläuft parallel zur Oberfläche 14, sie ist somit auch im wesentlichen parallel zur Unterseite 6 ausgerichtet. Die Oberfläche 16 schließt sich an die Oberfläche 15 an und verläuft schräg nach unten unter einem flachen Winkel zur Oberfläche 15. Die sich anschließende Oberfläche 17 ist entgegengesetzt nach oben ausgerichtet, wobei der Anstiegswinkel der Oberfläche 17 betragsmäßig größer als der Winkel der Oberfläche 16 ist, den dieser mit der horizontal verlaufenden Oberfläche 15 bildet. An die Oberfläche 17 schließt sich die Oberfläche 18 an, die parallel zur Oberfläche 12 und somit zur Oberseite 5 bzw. Unterseite 6 des Paneels 1 ausgerichtet ist.The bottom surface of the groove 34 is covered by surfaces 15, 16, 17 and 18 are formed, aligned as follows are. The surface 15 runs parallel to the surface 14, it is thus also essentially parallel to the underside 6 aligned. The surface 16 closes to the surface 15 and runs obliquely downwards at a flat angle to the surface 15. The itself adjoining surface 17 is opposite upwards aligned, the slope angle of the surface 17th is larger than the angle of the surface 16, that with the horizontally extending surface 15 forms. The surface closes to the surface 17 18 on, which is parallel to the surface 12 and thus to the top 5 or bottom 6 of the panel 1 is aligned.

Die Oberfläche 19 bildet die untere Endfläche der Kante 3 und ist im wesentlichen parallel zur Oberfläche 11 ausgerichtet. Vorzugsweise liegen die Oberflächen 11 und 19 dabei in einer Ebene. Die Oberfläche 19a bildet den Übergang zwischen den Oberflächen 18 und 19 und ist schräg nach innen gerichtet geneigt angeordnet.The surface 19 forms the lower end surface of the edge 3 and is aligned substantially parallel to surface 11. The surfaces 11 and 19 are preferably located doing it on one level. The surface 19a forms the transition between surfaces 18 and 19 and is oblique arranged inclined inwards.

Die Nut 34 des Paneels 1 wird somit durch eine obere Lippe 30 und eine untere Lippe 31 gebildet. Dabei wird die obere Lippe 30 durch die Oberflächen 5, 11, 11a, 12, 13 und 14 umrandet, wobei die Oberfläche 11 die Endfläche der oberen Lippe 30 bildet. Die untere Lippe 31 wird von den Oberflächen 6, 15, 16, 17, 18, 19 und 19a umgrenzt, wobei die Oberfläche 19 die Endfläche der unteren Lippe 31 bildet.The groove 34 of the panel 1 is thus through an upper lip 30 and a lower lip 31 are formed. The upper lip 30 through surfaces 5, 11, 11a, 12, 13 and 14 edged with surface 11 the end face the upper lip 30 forms. The lower lip 31 is from bounded by surfaces 6, 15, 16, 17, 18, 19 and 19a, surface 19 being the end surface of the lower lip 31 forms.

Fig. 2 zeigt ein Paneel 2, die an einer Kante 4 eine Feder 32 aufweist, die vorzugsweise integral mit dem Paneel 2 ausgebildet ist. Die Kante 4 weist eine obere Fläche 21 auf, die sich an die Oberseite 9 des Paneels 2 anschließt. Dabei verläuft die Oberfläche 21 im wesentlichen vertikal nach unten. Die Feder 32 wird von Oberflächen 22, 23, 24, 8, 25, 26, 27 und 28 umschlossen. Die Oberfläche 22 verläuft im wesentlichen horizontal und somit parallel zur Oberfläche 9 des Paneels 2. Die Oberfläche 23 ist unter einem flachen Winkel nach unten geneigt ausgerichtet und verbindet die beiden Oberflächen 22 und 24 miteinander. Die Oberfläche 24 ist wiederum parallel zur Oberseite 9 des Paneels 2 ausgerichtet und erstreckt sich somit im wesentlichen horizontal. Die Oberfläche 24 endet an der Endfläche 8 der Feder 32.Fig. 2 shows a panel 2, the edge 4 a spring 32, which is preferably integral with the panel 2 is formed. The edge 4 has an upper surface 21 on, which connects to the top 9 of the panel 2. The surface 21 runs essentially vertically down. The spring 32 is of surfaces 22, 23, 24, 8, 25, 26, 27 and 28 enclosed. The Surface 22 is essentially horizontal and thus parallel to surface 9 of panel 2. The surface 23 is inclined downward at a flat angle aligned and connects the two surfaces 22 and 24 with each other. The surface 24 is again parallel aligned to the top 9 of the panel 2 and extends thus essentially horizontal. The surface 24 ends at the end face 8 of the spring 32.

Die unteren Oberflächen der Feder 32 haben folgende Ausrichtungen. Die Oberfläche 25 grenzt an die Endfläche 8 an und verläuft parallel zur Oberfläche 24 bzw. im wesentlichen parallel zur Unterseite 10 des Paneels 2. Die Oberfläche 26 verläuft von der Endfläche 8 der Feder 32 wegweisend nach unten, während die Oberfläche 27 wieder schräg nach oben verlaufend ausgerichtet ist. Dabei ist der Steigungswinkel der Oberfläche 27 größer als der Winkel der Oberfläche 26, den diese mit der horizontalen einschließt. Die Oberfläche 28 schließt sich an die Oberfläche 27 an und geht in die Oberfläche 29 der Kante 4 über. Die Oberfläche 29 verläuft dabei im wesentlichen vertikal, also senkrecht zur Unterseite 10 des Paneels 2. Die Oberflächen 21 und 29 sind somit im wesentlichen parallel zueinander ausgerichtet, liegen jedoch nicht in einer Ebene, sondern die Oberfläche 29 ist geringfügig in Richtung des Körpers des Paneels 2 gegenüber der Oberfläche 21 zurück versetzt.The lower surfaces of the spring 32 have the following orientations. The surface 25 borders on the end surface 8 on and runs parallel to the surface 24 or substantially parallel to the bottom 10 of the panel 2. Die Surface 26 extends from end surface 8 of spring 32 groundbreaking down while the surface 27 again is aligned obliquely upwards. It is the slope angle of surface 27 is greater than the angle the surface 26 that this with the horizontal includes. The surface 28 adjoins the surface 27 and goes into the surface 29 of the edge 4 about. The surface 29 runs essentially vertical, i.e. perpendicular to the underside 10 of the panel 2. The surfaces 21 and 29 are thus essentially parallel aligned with each other, but are not in one Level, but the surface 29 is slightly in Direction of the body of the panel 2 with respect to the surface 21 moved back.

Fig. 3 zeigt die beiden Paneelen 1 und 2, die mechanisch miteinander verbunden sind. Dazu steht die Feder 32 des Paneels 2 mit der oberen Lippe 30 und der unteren Lippe 31 der Nut 34 des Paneels 1 in Eingriff.Fig. 3 shows the two panels 1 and 2, the mechanical are interconnected. This is the spring 32 of the Panels 2 with the upper lip 30 and the lower lip 31 of the groove 34 of the panel 1 in engagement.

Im verrasteten, bzw. verriegelten Zustand liegen die zuvor beschriebenen Oberflächen der Nut 34 einerseits und der Feder andererseits zumindest teilweise paarweise flächig aneinander an. Daraus ergeben sich zumindest die mit den offenen Dreiecken und den Großbuchstaben A, B, C und D gekennzeichneten Paare von Paßflächen 12,22; 14,24; 15,25 und 17, 27.They are in the locked or locked state described surfaces of the groove 34 on the one hand and the spring on the other hand at least partially in pairs to each other. This at least results in those with the open triangles and the capital letters A, B, C and D marked pairs of mating surfaces 12, 22; 14.24; 15, 25 and 17, 27.

Die beiden oberen Paßflächenpaare 12, 22 und 14, 24 wirken einem Höhenversatz der beiden gekuppelten Teile, also Feder 32 einerseits und Nut 34 aus Lippen 30 und 31 andererseits entgegen. Dadurch wird verhindert, daß dasPaneel 2 gegenüber dem Paneel 1 verkanten kann, insbesondere während des Zusammenfügens.The two upper mating surface pairs 12, 22 and 14, 24 act a height offset of the two coupled parts, so Spring 32 on the one hand and groove 34 from lips 30 and 31 on the other opposite. This prevents the panel 2 can tilt relative to the panel 1, in particular during assembly.

Beide Paare von Oberflächen 12, 22 und 14, 24 weisen gegenüberliegend angeordnete Paare von Oberflächen 15,25 und 17,27 als Widerlager auf. Durch diesen Paßsitz wird die Feder 32 sowohl am vorderen, der Endfläche 8 zugewandten Ende, als auch am hinteren, der Kante 4 zugewandten Ende in ihrer Position festgelegt. Dabei sind die Oberflächenpaare 14,24 und 15, 25 beabstandet zu den Oberflächenpaaren 12,22 und 17,27 angeordnet, wobei der Abstand möglichst groß gewählt ist. Dadurch wird eine hohe Stabilität und insbesondere Biegesteifigkeit gegenüber einer durch eine senkrecht auf die Oberflächen 5 und 9 der gekoppelten Paneelen 1 und 2 wirkenden Belastung erreicht.Both pairs of surfaces 12, 22 and 14, 24 face each other arranged pairs of surfaces 15.25 and 17.27 as an abutment. Through this fit the spring 32 both on the front, the end surface 8 facing End, as well as at the rear, the edge 4 facing End set in their position. Here are the Surface pairs 14, 24 and 15, 25 spaced from the Surface pairs 12,22 and 17,27 arranged, the Distance is chosen as large as possible. This makes a high one Stability and especially bending stiffness one by a perpendicular to the surfaces 5 and 9 the coupled panels 1 and 2 acting load reached.

Darüber hinaus können die zuvor beschriebenen Wirkungen auch dadurch verstärkt und verbessert werden, daß auch die Oberflächenpaare 13,23 und 16,26 paßgenau aneinander anliegen und somit die Biegesteifigkeit verbessern.In addition, the effects described above can also be strengthened and improved in that the surface pairs 13, 23 and 16, 26 fit together perfectly fit and thus improve the bending stiffness.

Bisher wurde das Zusammenwirken der Oberflächen in Bezug auf die Biegesteifigkeit beschrieben. Die Oberflächen 17 und 27 bewirken, daß die Feder 32 in der von den Lippen 30 und 31 gebildeten Nut 34 festgehalten wird. Denn durch die Oberflächen 26 und 27 wird ein nach unten vorstehendes Verriegelungselement 33 der Feder 32 gebildet, die in die von den Oberflächen 16 und 17 in der Nut 34 an der unteren Lippe 31 ausgebildete Vertiefung 35 eingreift. Wie mit dem Dreieck B gekennzeichnet ist, sind die Oberflächen 17 und 27 so geneigt, daß ein Herausrutschen der Feder 32 aus der Nut 34 wirkungsvoll verhindert wird.So far, the interaction of the surfaces has been related described on the bending stiffness. The surfaces 17 and 27 cause the spring 32 in the of the lips 30 and 31 formed groove 34 is held. Because by surfaces 26 and 27 become one protruding downward Locking element 33 of the spring 32 formed in that of the surfaces 16 and 17 in the groove 34 on the engages lower lip 31 formed recess 35. As marked with the triangle B, the surfaces are 17 and 27 inclined so that slipping out Spring 32 is effectively prevented from the groove 34.

Darüber hinaus sind die Nut 34 und die Feder 32 so genau aufeinander ausgerichtet, daß bei paßgenauem Sitz der Feder 32 in der Nut 34 die Oberflächen 11 und 21 der Kanten 3 und 4 der Paneelen 1 und 2 eng aneinander anliegen. Somit liegen die Oberflächen 9 und 5 ohne Spalt aneinander an und bilden eine durchgängige Oberfläche.In addition, the groove 34 and the tongue 32 are so accurate aligned with each other that with a snug fit of the spring 32 in the groove 34, the surfaces 11 and 21 of the edges 3 and 4 of panels 1 and 2 fit closely together. Consequently the surfaces 9 and 5 lie against each other without a gap and form a continuous surface.

Für ein Zusammenfügen werden beide Paneelen 1 und 2 horizontal, also im wesentlichen parallel zu den Unterseiten 6 und 10 aufeinander zu bewegt worden. Durch einen entsprechend ausgeübten mechanischen Druck drückt die Feder 32 die untere Lippe 31 nach unten, bis die Feder 32 soweit in die Nut 34 eingeschoben worden ist, bis die untere Lippe 31 mit der Feder 32 verrastet. Den verrasteten Zustand zeigt Fig. 3. Dabei ist hervorzuheben, daß nur die vertikal zu den Oberseiten 5 und 9 verlaufenden Oberflächen 11 und 21 aneinander anliegen und somit die relative Position der beiden Paneelen 1 und 2 definieren. Die weiteren vertikalen Oberflächenpaare 7 und 8 sowie 19 und 29 haben dagegen keine direkten mechanischen Kontakt miteinander.For joining, both panels 1 and 2 are horizontal, essentially parallel to the undersides 6 and 10 have been moved towards each other. By one accordingly Mechanical pressure exerts pressure on the spring 32 the lower lip 31 down until the spring 32 as far has been inserted into the groove 34 until the lower Lip 31 locked with the spring 32. The locked one Condition shows Fig. 3. It should be emphasized that only the surfaces running vertically to the tops 5 and 9 11 and 21 abut each other and thus the relative Define the position of the two panels 1 and 2. The further vertical surface pairs 7 and 8 and 19 and 29 have no direct mechanical contact with each other.

Fig. 3 zeigt weiterhin, daß die beiden Profile im verriegelten Zustand im Bereich der Oberflächen 11 und 21 sowie 7 und 8 Hohlräume bilden. Dieses dient einer Aufnahme von ggf. vorhandenen Verunreinigungen, damit die Passung zwischen den Paßflächen nicht beeinträchtigt wird. Die Hohlräume können auch Leim aufnehmen, sofern dieses für eine Fixierung der eingenommenen Position erwünscht ist. Es wird jedoch hervorgehoben, daß für das mechanische Verriegeln kein Leim erforderlich ist.Fig. 3 also shows that the two profiles in the locked Condition in the area of surfaces 11 and 21 as well 7 and 8 form cavities. This serves to record any contamination, so that the fit between the mating surfaces are not affected. The cavities can also absorb glue if this is for a Fixation of the position taken is desired. It however, it is emphasized that for mechanical locking no glue is required.

Sowohl das Paneel 1 als auch das Paneel 2 können umseitig entweder mit dem in Fig. 1 dargestellten Profil oder mit dem in Fig. 2 dargestellten Profil versehen sein, so daß eine Mehrzahl von Paneelen 1 und 2 zu einer flächigen Anordnung miteinander verbunden werden können. Dazu weisen die Paneelen jeweils eine Längs- und eine Querseite ein Profil gemäß Fig. 1 und an den anderen Seiten gemäß Fig. 2 auf.Both panel 1 and panel 2 can be overleaf either with the profile shown in Fig. 1 or with the profile shown in Fig. 2, so that a plurality of panels 1 and 2 to form a flat arrangement can be connected to each other. Point to this the panels each have a long and a short side 1 and on the other sides according to FIG. 2 on.

Das in den Fig. 1 bis 3 dargestellte Ausführungsbeispiel zeigt jeweils einstückige Ausführungen der Nut 34 in dem Paneel 1 einerseits und der Feder 32 in bzw. an dem Paneel 2. Selbstverständlich ist es auch möglich, die Feder 32 und/oder die untere Lippe 31 mehrstückig auszuführen, also bspw. Kunststoffprofile zu verwenden, die in Kombination mit den Holzwerkstoffen des Paneels eingesetzt werden. Die Erfindung ist daher nicht auf einer einstükkige Ausführung beschränkt.The embodiment shown in FIGS. 1 to 3 each shows one-piece versions of the groove 34 in the Panel 1 on the one hand and the spring 32 in or on the panel 2. Of course it is also possible to use the spring 32 and / or to execute the lower lip 31 in several pieces, So to use plastic profiles, for example, in combination used with the wood materials of the panel become. The invention is therefore not based on one piece Limited execution.
