Abstract

Device for locking together interconnected structural panels (1a, 2a), especially floor panels, comprises a core of wood material having on at least one edge a groove (4a) and on the opposite-lying edge a tongue (3a) corresponding to the groove. Two interconnected panels are locked together by the tongue and groove connection in a horizontal (H) or a vertical direction (V). The tongue and the groove are each provided with at least one recess (5). The recesses lie opposite each other when the plates are interconnected. An insert (7) engaging in the recesses has at least one elastic lip (7') which is used to lock the panel in the other, either vertical or horizontal, direction. Preferred Features: The insert is a plastic injection-molded part having two lips.

Description

Die Erfindung betrifft eine Einrichtung zum Verriegeln von miteinander verbundenen Bauplatten, insbesondere Bodenpaneelen, mit einem Kern aus Holzwerkstoff, die an mindestens einer Kante mit einer Nut und an der gegenüberliegenden Kante mit einer zu der Nut korrespondieren Feder versehen sind, wobei zwei miteinander verbunden Platten durch die Feder-Nut-Verbindung in einer horizontalen oder einer vertikalen Richtung verriegelt sind und wobei die Feder und die Nut mit mindestens einer Ausnehmung versehen sind, die sich bei miteinander verbundenen Platten im Wesentlichen gegenüber liegen.The invention relates to a device for locking interconnected Building boards, in particular floor panels, with a core made of wood-based material, on at least one edge with a groove and on the opposite edge are provided with a tongue corresponding to the groove, two with each other connected panels by the tongue and groove connection in a horizontal or locked in a vertical direction and wherein the tongue and groove are provided with at least one recess which are connected to one another Plates are essentially opposite.

Eine solche Einrichtung ist beispielsweise aus der DE 200 21 779 U1 bekannt. Zunächst wird die Feder der einen Platte in die Nut der anderen Platte eingeführt und dann wird der die Verriegelung bewirkende Einsatz stirnseitig in die sich gegenüberliegenden Ausnehmungen von Feder und Nut, die einen Kanal bilden, eingeschoben. Die Haltbarkeit der Verbindung ist hoch, das Verlegen jedoch recht mühsam und zeitaufwändig. Wenn der Einsatz nicht vollständig in den Kanal eingeschoben wird und heraussteht, lassen sich weitere Paneele an der Stirnseite nicht mehr exakt anlegen und es entsteht an der Oberfläche des verlegten Bodens eine Fuge, die ein unerwünschtes Erscheinungsbild ergibt. Außerdem besteht die Gefahr, dass Feuchtigkeit in die Fuge eindringt und der Kern der Platten aufquillt.Such a device is known for example from DE 200 21 779 U1. First the tongue of one plate is inserted into the groove of the other plate and then the insert causing the locking is inserted into the opposite side Recesses of tongue and groove, which form a channel, inserted. The durability of the connection is high, but the laying is quite tedious and time consuming. If the insert is not completely in the channel inserted and protruding, there are additional panels on the front no longer apply exactly and it is created on the surface of the installed Floor a joint that gives an undesirable appearance. There is also the risk of moisture entering the joint and the core of the panels swells.

Von dieser Problemstellung ausgehend, soll die eingangs erläuterte Einrichtung so verbessert werden, dass ihre Handhabung und das Verlegen der Platten einfacher wird.Proceeding from this problem, the device explained at the beginning should be like this be improved to make their handling and laying of the boards easier becomes.

Zur Problemlösung zeichnet sich eine gattungsgemäße Einrichtung durch einen in die Ausnehmungen eingreifenden Einsatz aus, der mindestens eine federnde Lippe aufweist und mit dem die Platten in der anderen, entweder vertikalen oder horizontalen Richtung verriegelbar sind.To solve the problem, a generic device is characterized by an in the recesses engaging insert, the at least one resilient lip and with which the panels in the other, either vertical or horizontal direction can be locked.

Der mit einer federnden Lippe versehene Einsatz bietet den Vorteil, dass er zunächst in eine der Ausnehmungen eingesetzt werden kann und die Platten dann ineinander geschnappt werden können, weil die federnde Lippe ausweichen kann bzw. zusammengedrückt wird und zurückfedert, wenn die korrespondiere Ausnehmung an der Feder bzw. der Nut zur Überdeckung gelangt. Wie ein Widerhaken greift die federnde Lippe in die Ausnehmung ein und verriegelt die Platten.The insert with a resilient lip offers the advantage that it initially can be inserted into one of the recesses and then the plates can be snapped together because the resilient lip can dodge or is compressed and springs back when the corresponding recess overlap on the tongue or groove. Like a barb engages the resilient lip in the recess and locks the plates.

Vorzugsweise weist der Einsatz mehrere federnde Lippen auf, die zueinander V-förmig oder X-förmig angeordnet sein können.The insert preferably has a plurality of resilient lips which are V-shaped with respect to one another or can be arranged in an X-shape.

Insbesondere vorteilhaft ist es, wenn die federnde Lippe an einem massiven Kern ausgebildet ist. Der massive Kern kann werkseitig in eine der Ausnehmungen eingesetzt und darin befestigt werden. Die Verbindung der Platten ist dann genauso einfach möglich, wie bei den sogenannten Klick- oder Schnappprofilen, bei denen die Verriegelungsmittel einteilig mit der Feder bzw. der Nut ausgebildet sind. It is particularly advantageous if the resilient lip on a solid core is trained. The solid core can be factory-fitted in one of the recesses used and fixed in it. The connection of the plates is then the same easily possible, as with the so-called click or snap profiles, at which the locking means are integrally formed with the tongue or groove are.

Der Einsatz ist vorzugsweise als Kunststoff-Spritzgussteil ausgebildet, so dass eine kostengünstige und einfache Herstellung möglich ist. Es kann auch extrudiert werden. Durch eine entsprechende Materialauswahl wird sichergestellt, dass Kräfte, wie sie auf die Platten bei normaler Nutzung einwirken, nicht zu einer Deformation der Federlippe und damit zum Lösen der Verbindung führen. The insert is preferably designed as a plastic injection molded part, so that an inexpensive and simple manufacture is possible. It can also be extruded become. Appropriate material selection ensures that that forces that act on the plates during normal use do not become one Deformation of the spring lip and thus lead to the loosening of the connection.

Figur 1 zeigt zwei miteinander verbundene Bodenpaneele 1, 2, die über die in der Nut 4 des einen Paneels 2 sitzende Feder 3 des anderen Paneels 1 in vertikaler Richtung V miteinander verriegelt sind. In der Oberlippe 8 der Nut 4 ist eine Ausnehmung 5 vorgesehen, die zu einer in der Feder 3 vorgesehenen Ausnehmung 6 korrespondiert. Die Verriegelung in horizontaler Richtung erfolgt durch den im Querschnitt X-förmigen Einsatz 7 mit 4 federnden Lippen 7 I, 7 II, 7 III, 7 IV. Der Einsatz 7 ist werkseitig in die Ausnehmung 6 oder die Ausnehmung 5 eingesetzt und darin vorzugsweise verklebt. Werden die Paneele 1, 2 in horizontaler Richtung H aufeinander zugeschoben, federn die Lippen 7 I, 7 II, oder 7 III, 7 IV aufeinander zu, biegen dann seitlich aus und wenn die entsprechende Ausnehmung in der Oberlippe 8 oder der Feder 3 zur Überdeckung mit den federnden Lippen 7 I, 7 II, 7 III, 7 IV kommt, federn diese wieder zurück.Figure 1 shows two interconnected floor panels 1, 2, which are locked in the vertical direction V via the spring 3 of the other panel 1 seated in the groove 4 of the one panel 2. A recess 5 is provided in the upper lip 8 of the groove 4, which corresponds to a recess 6 provided in the tongue 3. The locking in the horizontal direction takes place through the cross-sectionally X-shaped insert 7 with 4 resilient lips 7 I , 7 II , 7 III , 7 IV . The insert 7 is factory-fitted in the recess 6 or the recess 5 and is preferably glued therein. If the panels 1, 2 are pushed towards one another in the horizontal direction H, the lips 7 I , 7 II , or 7 III , 7 IV spring towards one another, then bend sideways and if the corresponding recess in the upper lip 8 or the spring 3 overlaps comes with the resilient lips 7 I , 7 II , 7 III , 7 IV , they spring back again.

Bei dem in Figur 2 dargestellten Ausführungsbeispiel sind in die Oberlippe 8 und die Feder 3 Ausnehmungen 5, 6 eingefräst, die bei miteinander verbundenen Paneelen 1, 2 einen im Querschnitt dreieckigen Kanal ausbilden. Der Einsatz 7 ist im Querschnitt V-förmig mit zwei federnden Lippen 7 ', 7 " ausgebildet. Der Einsatz 7 wird werkseitig in die Ausnehmung 6 in der Feder 3 eingesetzt und hierin verklebt. Werden die Paneele 1, 2 horizontal ineinander geschoben, biegen die federnden Lippen 7 ', 7 " so weit aus, bis sie in die Nut 5 der Oberlippe 8 eintauchen können.In the embodiment shown in Figure 2 are in the upper lip 8 and the spring 3 recesses 5, 6 milled in the case of interconnected panels 1, 2 form a channel with a triangular cross section. The insert is 7 V-shaped in cross section with two resilient lips 7 ', 7 ". The insert 7 is inserted in the recess 6 in the spring 3 at the factory and therein bonded. If the panels 1, 2 are pushed horizontally into each other, they bend resilient lips 7 ', 7 "until they dip into the groove 5 of the upper lip 8 can.

Bei dem in Figur 5 dargestellten Ausführungsbeispiel sind die Paneele 1a, 2a mit vertikaler Nut 4a und Feder 3a versehen. Eine solche Profilausgestaltung wird vielfach als Legeprofil bezeichnet, weil die Paneele 1a, 2a nicht durch horizontales Verschieben, sondern durch vertikales Einlegen miteinander verbunden werden. Bei dieser Profilart werden die Paneele 1a, 2a über die Feder-Nut-Verbindung in horizontaler Richtung H verriegelt. In der Feder 3a ist an der Stirnseite über die volle Länge eine im Querschnitt rechteckige Nut eingefräst. In der Stirnwand der Nut 4a ist gegenüberliegend hierzu eine Ausnehmung 5 über die volle Länge des Paneels 1a eingefräst. Der Einsatz 7 ist mit einem im Querschnitt rechteckigen Kern 7a versehen, der in die Nut in der Feder 3 werkseitig eingesetzt ist. An den Kern schließt sich eine V-förmige Lippe an, die in einer federnden Lippe 7 I endet. Werden die beiden Paneele 1a, 2a ineinander gelegt, wird die federnde Lippe 1a an den Kern 7a des Einsatzes 7 angelegt und federt in horizontaler Richtung H zurück, wenn die Feder 3a so weit in die Nut 4a eingetaucht ist, dass die Ausnehmung 5 zur Überdeckung mit dem Satz 7 gelangt. In vertikaler Richtung V sind die Paneele 1a, 2a dann verriegelt.In the embodiment shown in Figure 5, the panels 1a, 2a are provided with a vertical groove 4a and tongue 3a. Such a profile design is often referred to as a laying profile because the panels 1a, 2a are not connected to one another by horizontal displacement, but rather by vertical insertion. In this type of profile, the panels 1a, 2a are locked in the horizontal direction H via the tongue and groove connection. In the spring 3a, a groove with a rectangular cross section is milled on the front side over the full length. In the end wall of the groove 4a, opposite this, a recess 5 is milled over the full length of the panel 1a. The insert 7 is provided with a core 7a with a rectangular cross section, which is factory-fitted in the groove in the spring 3. A V-shaped lip adjoins the core and ends in a resilient lip 7 I. If the two panels 1a, 2a are placed one inside the other, the resilient lip 1a is placed against the core 7a of the insert 7 and springs back in the horizontal direction H when the tongue 3a is immersed so far in the groove 4a that the recess 5 overlaps arrives with the sentence 7. The panels 1a, 2a are then locked in the vertical direction V.

Durch die L-förmige Ausbildung der Kanten der Paneele 1a, 2a kann an dem unteren Schenkel 10a des Paneels 1a eine weitere im Querschnitt rechteckige Nut eingefräst sein, in die ein zweiter Einsatz 7 eingelegt werden kann. Durch eine entsprechende Ausnehmung 9 in der Stirnseite des vertikalen Schenkels 11a des Paneels 2a kann eine weitere Verriegelungsmöglichkeit für die federnde Lippe 7a des zweiten Einsatzes 7 geschaffen werden, wodurch die notwendigen Auszugskräfte in vertikaler Richtung V in der Verbindung erhöht werden. Due to the L-shaped design of the edges of the panels 1a, 2a can be on the lower Leg 10a of the panel 1a another groove with a rectangular cross section be milled into which a second insert 7 can be inserted. By a corresponding recess 9 in the end face of the vertical leg 11a of the Panels 2a can be a further locking option for the resilient lip 7a of the second insert 7 are created, whereby the necessary pull-out forces can be increased in the vertical direction V in the connection.
