Abstract

The panel has a wooden support panel (2) with a covering layer (3,4;5,6) on an upper surface. The plate has edge faces with multiple tongue and groove formations to allow the panels to interlock. Each outer edge face has a groove (7,10) and a tongue (8) which interlock with corresponding formations on adjacent panels and are superimposed. Each lower groove (7) is larger than the respective upper tongue or groove (10). the grooves and tongues can have a tapered cross section or can be wedge shaped.

Description

Die Erfindung betrifft ein insbesondere für Fußbodenbeläge bestimmtes Paneel, das eine aus Holzwerkstoff bestehende tragende Platte aufweist, die zumindest auf einer Oberfläche mit einer Beschichtung versehen ist, wobei die Platte an ihren Kanten bzw. Rändern Nuten und Federn aufweist, die in bzw. auf entsprechende Nuten und Federn weiterer gleicher Paneele passen.The invention relates to a particular intended for floor coverings panel, which has a bearing material made of wood material supporting plate, which is provided at least on a surface with a coating, the plate having at its edges or edges grooves and springs, in or on corresponding Grooves and springs fit other identical panels.

Bei der Verlegung derartiger Paneele zu Fußböden wird auf die Oberseite der Federn der einzelnen Paneele Leim aufgetragen, bevor die Federn in die entsprechenden Nuten der Gegenpaneele eingesteckt werden. Der auf die Federn aufgetragene Leim wird beim Einstecken in eine Nut eines Gegenpaneels verdrängt und weicht nicht nur in die tiefer als die Höhe der Feder ausgebildete Nut aus, sondern gelangt auch zur Oberseite der zusammengesteckten Paneele, so daß eine Verleimung nicht nur im Kontaktbereich zwischen der Oberfläche der Feder und der gegenüberliegenden Wand der Nut, sondern auch an den Stoßstellen zwischen den zusammengesteckten Paneelen stattfindet. An die Oberseite der zusammengesteckten Paneele ausgetretener Leim wird durch Abwischen von der Oberfläche entfernt.When laying such panels to floors glue is applied to the top of the springs of the individual panels before the springs are inserted into the corresponding grooves of the Gegenpaneele. The applied to the feathers glue is displaced upon insertion into a groove of a Gegenpaneels and not only deviates into the deeper than the height of the spring formed groove, but also reaches the top of the assembled panels, so that a glue not only in the contact area between the Surface of the spring and the opposite wall of the groove, but also takes place at the joints between the mated panels. At the top of the assembled panels of leaked glue is removed by wiping from the surface.

Da wegen schwankender Fertigungstoleranzen der ineinanderzusteckenden Federn und Nuten sowie der zusammenzusteckenden Paneele Auskehlungen im Bereich zwischen dem Übergang der Federn zu den Stirnseiten bzw. Rändern der Paneele sowie eine größere Tiefe der Nuten als die vorstehende Höhe der einzusteckenden Federn notwendig sind, ist der für eine Klebeverbindung zwischen den Federn und Nuten und den aneinanderstoßenden Stirnenden bzw. Rändern der zusammenzusteckenden und miteinander zu verbindenden Paneele vorhandene Bereich verhältnismäßig gering.Since, due to fluctuating manufacturing tolerances of the springs and grooves to be nested and the panels to be assembled together, grooves in the area between the transition of the springs to the end faces or edges of the panels as well as a greater depth of the grooves than the projecting height of the springs to be inserted are necessary, this is for an adhesive bond between the springs and grooves and the abutting front ends or edges of the zusammenzusteckenden and interconnecting panels existing area relatively low.

Wegen dieser Problematik kommt es häufig zu Fehlern oder Schwachstellen bei der Verlegung von Fußböden mit aus derartigen Paneelen zusammengesetzten Belägen, die dazu führen, daß die Klebzonen zwischen Paneelen zumindest teilweise reißen und damit im Belag Risse oder sonstige Öffnungen entstehen, durch die Luftfeuchtigkeit und insbesondere für Reinigungszwecke verwendetes Wasser eindringen kann. Ist einmal Feuchtigkeit in eine Stoß- und Klebstelle zwischen aneinanderstoßenden Paneelen eingedrungem, beginnt das Material der aus Holzwerkstoff bestehenden Paneele zu arbeiten, was schließlich zu einem Werfen des verlegten Fußbodenbelages führt. Ein derart schadhaft gewordener Fußboden ist nicht mehr zu reparieren. Vielmehr muß er vollständig ausgewechselt werden.Because of this problem, it often leads to errors or weaknesses in the installation of floors with such panels composite coverings, which cause the adhesive zones between panels at least partially tear and thus cracks or other openings in the lining caused by the humidity and especially for Cleaning used water can penetrate. Once moisture has penetrated into a joint and joint between abutting panels, the material of the panels made of wood material begins to work, which eventually leads to a throwing of the laid floor covering. Such a damaged floor is beyond repair. Rather, it must be completely replaced.

Solche Schäden an aus über Nut- und Federverbindungen verlegten Paneelen bestehenden Fußböden entstehen nicht nur bei unsachgerechter Verlegung, sondern auch dann, wenn die Paneele sorgfältig auf einem sorgfältig vorbereiteten Untergrund fachgerecht verlegt werden und auch nur kleinste Unebenheiten auf dem Untergrund vorhanden sind und nach dem Verlegen des Fußbodenbelages Veränderungen des Untergrundes Unebenheiten des Untergrundes entstehen, beispielsweise durch Setzungen im Gebäude, in welchem der Fußboden verlegt ist.Such damage to panels installed over tongue and groove joints is not only due to improper installation, but also if the panels are carefully laid on a carefully prepared surface and even the smallest bumps on the surface are present and after laying of the floor covering Changes in the surface Unevenness of the surface occurs, for example due to subsidence in the building in which the floor is laid.

Der Erfindung liegt die Aufgabe zugrunde, die Verbindung zwischen Nut und Feder aufweisenden, nebeneinander zu verlegenden Paneelen und insbesondere Fußbodenpaneelen derart zu verbessern, daß auch dann, wenn kleinere Unebenheiten im Untergrund vorhanden sind oder sich nach dem Verlegen des Fußbodenbelages ergeben, sich keine Schäden im Bereich der Stoßstellen der Paneele einstellen können, die auf die Dauer dazu führen würden, daß der Fußbodenbelag ganz ausgewechselt werden muß.The invention has for its object to improve the connection between tongue and groove, side by side to be laid panels and in particular floor panels to improve such that even if minor bumps are present in the ground or arise after laying the floor covering, no damage in Adjust the range of joints of the panels, which would lead in the long run that the floor covering must be completely replaced.

Diese Aufgabe wird erfindungsgemäß mit einem Paneel gelöst, welches die Merkmale des Patentanspruches 1 aufweist. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved with a panel having the features of claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

Durch die Erfindung wird eine doppelte Nut-Feder-Verbindung für Paneele und insbesondere Fußbodenpaneele geschaffen, die gegenüber üblichen verleimbaren Nut-Feder-Verbindungen vergrößerte Kontaktflächen an den Verbindungsstellen und damit größere Verleimungsbereiche ermöglicht. Dadurch ergibt sich ein besserer Halt bzw. eine verbesserte Stabilität zwischen den zusammengesteckten und miteinander verleimten Paneelen, wenn diese auf einem nicht ganz ebenen Untergrund verlegt sind. Auch lassen sich durch die Erfindung Verlegungsfehler weitgehend vermeiden.The invention provides a double tongue-and-groove connection for panels and in particular floor panels, which compared to conventional glued tongue and groove connections allows enlarged contact surfaces at the connection points and thus larger gluing areas. This results in a better grip or improved stability between the assembled and glued together panels, if they are laid on a not quite flat surface. Also can be largely avoided by the invention misplacement errors.

In the drawing, an embodiment of inventively constructed panels is shown schematically, and that shows
Fig. 1
a cross-section of two adjacent to be joined by mating together inventively formed panels before mating and
Fig. 2
a cross section of the assembled panels of Fig. 1, wherein the gluing areas are displayed and thus to recognize.

Jedes Paneel 1 weist eine aus Holzstoff wie HDF (High Density Fibre) , MDF (Medium Density Fibre) oder Span-Holzstoff bestehende tragende Platte 2 auf, welche an der Oberseite mit einer als Oberfläche dienenden, beispielsweise aus bedrucktem Papier bestehenden Deckschicht 3 versehen ist. Über dieser Deckschicht 3 ist eine verschleißfeste, durchsichtige Abdeckschicht 4 angeordnet.Each panel 1 has a wooden plate such as HDF (High Density Fiber), MDF (Medium Density Fiber) or chip wood pulp existing supporting plate 2, which is provided at the top with serving as a surface, consisting for example of printed paper top layer 3 , Over this cover layer 3, a wear-resistant, transparent cover layer 4 is arranged.

An der Unterseite ist jede tragende Platte 2 mit einer der Stabilisierung dienenden weiteren Deckschicht 5 versehen, die ebenfalls unter einer Abdeckschicht 6 angeordnet ist, welche jedoch nicht durchsichtig sein muß, weil die Deckschicht 5 nicht wie die Deckschicht 3, ein Oberflächendekor bildet.At the bottom, each supporting plate 2 is provided with a further covering layer 5 serving for stabilization, which is likewise arranged under a covering layer 6, which, however, is not transparent must be because the top layer 5 does not form like the top layer 3, a surface decor.

Jedes Paneel weist an einer Längskante und einer Stirnkante eine durchgehende und sich nach innen leicht konisch verjüngende tiefe Nut 7 sowie eine nach außen vorstehende, keilförmige Nase 8 auf, die als eine Art Feder dient.Each panel has on a longitudinal edge and a front edge a continuous and inwardly slightly tapered conical deep groove 7 and an outwardly projecting wedge-shaped nose 8, which serves as a kind of spring.

An der zweiten Längskante und der zweiten Stirnkante ist jedes Paneel 1 mit einer in die tiefe Nut 7 eines gleichen Paneels passenden konischen Feder 9 versehen, oberhalb der sich eine keilförmige Nut 10 befindet, in welche die keilförmige Nase 8 eines gleichen Paneels 1 paßt. Fig. 2 zeigt, wie die konische Feder 9 in eine Nut 7 und die keilförmige Nase 8 in eine keilförmige Nut 10 zusammengehörenden Paneele 1 passen.At the second longitudinal edge and the second end edge of each panel 1 is provided with a matching in the deep groove 7 of a same panel conical spring 9, above which there is a wedge-shaped groove 10, in which the wedge-shaped nose 8 of a same panel 1 fits. Fig. 2 shows how the conical spring 9 in a groove 7 and the wedge-shaped nose 8 fit into a wedge-shaped groove 10 belonging panels 1.

Jede Nase 8 ist kürzer als die Tiefe der zugehörigen Nut 10 und jede Feder 9 ist kürzer als die Tiefe der zugehörigen Nut 7 ausgebildet, so daß in jeder Nut 7 und 10 ein freier Raum 11 bzw. 12 verbleibt, wenn zwei Paneele 1, wie Fig. 2 zeigt, ineinandergesteckt sind.Each lug 8 is shorter than the depth of the associated groove 10 and each spring 9 is formed shorter than the depth of the associated groove 7, so that in each groove 7 and 10, a free space 11 or 12 remains when two panels 1, as Fig. 2 shows, are inserted one inside the other.

Beim Verlegen eines Belages wie eines Fußbodenbelages mit Paneelen 1 der in der Zeichnung gezeigten Art wird auf die Oberseite 13 jeder Feder 9 Leim aufgetragen. Zusätzlich kann, jedoch ist dies nicht in jedem Falle notwendig, auf die Unterseite 14 der Feder 9 weiterer Leim aufgetragen werden.When laying a covering such as a floor covering with panels 1 of the type shown in the drawing 9 glue is applied to the top 13 of each spring. In addition, but this is not necessary in any case, be applied to the bottom 14 of the spring 9 more glue.

Werden nun zwei Paneele 1 aus der in Fig. 1 gezeigten Position in die in Fig. 2 gezeigte Position zusammengesteckt, so gelangt die Oberseite 13 jeder Feder 9 mit der oben liegenden Innenseite 15 jeder Nut 7 in Kontakt, ebenso wie die Unterseite 14 der Feder 9 mit der unten liegenden Innenseite 16 der keilförmig oder konisch ausgebildeten Nut 7 in Kontakt kommt, wie Fig. 2 zeigt. Die Kontaktbereiche 17 und 18 sind in Fig. 2 zu erkennen.If two panels 1 are now plugged together from the position shown in FIG. 1 into the position shown in FIG. 2, the upper side 13 of each spring 9 comes into contact with the upper inner side 15 of each groove 7, as does the underside 14 of the spring 9 comes with the underlying inner side 16 of the wedge-shaped or conical groove 7 in contact, as shown in FIG. 2. The contact areas 17 and 18 can be seen in FIG.

Beim Zusammenstecken zweier Paneele 1 wird auf der Oberseite 13 und gegebenenfalls der Unterseite 14 jeder konischen Feder 9 befindlicher Leim abgestrichen und gleichmäßig über die Kontaktbereiche 17 und 18 verteilt. Überschüssiger Leim kann in die freien Räume 11 und 12 sowie einen an der Unterseite benachbarter Paneele befindlichen weiteren freien Raum 19 ausweichen. In den freien Raum 12 gelangender überschüssiger Leim wird beim Zusammenstecken von zwei Paneelen auf die Oberseite 20 jeder keilförmigen Nase 8 und die Innenseite 21 jeder keilförmigen Nut 10 verdrängt, so daß eine zusätzliche Verleimung im Kontaktbereich 22 zwischen der Oberseite der keilförmigen Nase 8 und der keilförmigen Nut 10 entsteht.When mating two panels 1 is on the top 13 and optionally the bottom 14 of each conical spring 9 befindlicher glue stripped and evenly distributed over the contact areas 17 and 18. Excess glue can escape into the free spaces 11 and 12 and a further free space 19 located on the underside of adjacent panels. In the free space 12 reaching excess glue is displaced upon mating of two panels on the top 20 each wedge-shaped nose 8 and the inner side 21 of each wedge-shaped groove 10, so that an additional glue in the contact area 22 between the top of the wedge-shaped nose 8 and the wedge-shaped Groove 10 is created.

Schließlich gelangen zusammengesteckte Paneele 1 auch im Bereich ihrer oberhalb der Nasen 8 und Nuten 10 befindlichen senkrechten Stirnseiten 23 in Kontakt miteinander, so daß auch hier in einem Kontaktbereich 24 eine Verleimung stattfindet. Überschüssiger Leim, der aus dem Kontaktbereich 24 auf die Oberfläche der zusammengesteckten Paneele 1 austritt, wird nach dem Zusammenstecken der Paneele vom Verleger abgewischt, bevor er aushärtet.Finally, mated panels 1 also come into contact with each other in the region of their vertical end faces 23 situated above the lugs 8 and grooves 10, so that gluing also takes place here in a contact region 24. Excess glue, which exits the contact area 24 on the surface of the assembled panels 1, is wiped from the publisher after the mating of the panels before it hardens.

An der Unterseite der zusammengesteckten Paneele 1 verbleibt ein offener Spalt 25, in und durch den gegebenenfalls weiterer überschüssiger Leim entweichen kann. Hier ist ein Kontakt zwischen den zusammengesteckten Paneelen 1 nicht notwendig.At the bottom of the assembled panels 1 remains an open gap 25, in and through which optionally further excess glue can escape. Here a contact between the assembled panels 1 is not necessary.

Wegen der in der Zeichnung gezeigten und vorstehend beschriebenen speziellen doppelten Nut-Feder-Verbindung der zusammengesteckten Paneele 1 ist die mit Hilfe von Leim erzielte feste Verbindung zwischen den Paneelen stabiler als bei einfachen Nut-Feder-Verbindungen, so daß ein aus den Paneelen 1 verlegter Fußbodenbelag auch dann die notwendige Stabilität aufweist, wenn der Untergrund nicht absolut eben ist. Dementsprechend besteht auch nicht die Gefahr, daß aus den Paneelen 1 verlegte Fußbodenbeläge im Bereich von Verbindungsstellen reißen können und in dadurch entstehende Risse Feuchtigkeit eindringen kann, was zu einem Werfen bzw. Aufwerfen des Fußbodenbelages und damit zu einer Zerstörung des gesamten Fußbodens führen kann.Because of the shown in the drawing and described above special double tongue and groove joint of the assembled panels 1, the achieved with the help of glue solid connection between the panels is more stable than in simple tongue and groove joints, so that a verlegter from the panels 1 Floor covering also has the necessary stability, if the surface is not absolutely flat. Accordingly, there is also no risk that can be torn from the panels 1 laid floor coverings in the region of joints and moisture can penetrate into resulting cracks, which can lead to a throwing or raising the floor covering and thus to the destruction of the entire floor.
