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 panel intended in particular for floor coverings has a load-bearing plate made of wood-based material, at least on one surface is provided with a coating, the plate at its edges Has grooves and tongues, which in or on corresponding grooves and tongues further same panels fit.

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 on floors, the top of the springs individual panels of glue are applied before the springs in the corresponding grooves of the Counter panels are inserted. The glue applied to the feathers is used in the Inserting into a groove of a counter panel displaces and not only gives way to the deeper than the height of the tongue formed groove, but also reaches the top of the assembled panels, so that gluing not only in the contact area between the surface of the tongue and the opposite wall of the groove, but also takes place at the joints between the assembled panels. To the Glue spilled from the top of the assembled panels is removed by wiping removed 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.Because of fluctuating manufacturing tolerances of the nested springs and Grooves and the panels to be plugged in grooves in the area between the Transition of the springs to the end faces or edges of the panels as well as a larger one Depth of the grooves than the protruding height of the springs to be inserted is necessary the one for an adhesive connection between the tongues and grooves and the butting ends or edges of the to be plugged together and panels to be connected to one another are relatively small.

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, errors or weak points often occur in the Laying of floors with coverings composed of such panels, the cause the adhesive zones between panels to at least partially tear and thus Cracks or other openings appear in the covering due to the air humidity and water used in particular for cleaning purposes can penetrate. Once upon a time Moisture in an abutting and gluing point between abutting panels penetrated, the material of the panels made of wood-based material begins to close work, which ultimately leads to a throw of the installed floor covering. On Floor that has become damaged can no longer be repaired. Rather, he has to be replaced completely.

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 consisting of tongue and groove connections Floors are created not only when improperly installed, but also when the panels are carefully laid on a carefully prepared surface and there are even the smallest bumps on the surface and after laying the floor covering, changes in the surface unevenness of the subsoil, 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 the connection between tongue and groove having panels to be laid side by side and in particular To improve floor panels in such a way that even if there are minor bumps in the Are present or arise after laying the floor covering, no damage can occur in the area of the joints of the panels that affect the Duration would result in the floor covering having to be replaced completely.

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 according to the invention with a panel which has the features of Claim 1. Advantageous embodiments of the invention are the subject of subclaims.

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 are created which are compared to conventional gluable tongue and groove connections enlarged contact areas at the connection points and thus allows larger gluing areas. This results in a better hold or one improved stability between the mated and glued together Panels if they are laid on a surface that is not quite level. Let too largely avoid misplacement by the invention.

In der Zeichnung ist ein Ausführungsbeispiel von erfindungsgemäß ausgebildeten Paneelen schematisch dargestellt, und zwar zeigt

Fig. 1
einen Querschnitt von zwei benachbarten durch Zusammenstecken miteinander zu verbindenden erfindungsgemäß ausgebildeten Paneelen vor dem Zusammenstecken und
Fig. 2

In the drawing, an embodiment of panels designed according to the invention is shown schematically, namely shows
Fig. 1
a cross section of two adjacent panels according to the invention to be connected by plugging together before plugging together and
Fig. 2
a cross section of the assembled panels of Fig. 1, wherein the gluing areas are displayed and thus can be seen.

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 one made of wood like HDF (High Density Fiber), MDF (Medium Density Fiber) or Span-Holzstoff existing load-bearing plate 2, which on the Top side with a surface, for example made of printed paper existing top layer 3 is provided. Over this top layer 3 is one 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 is each load-bearing plate 2 with a stabilizing one provided another cover layer 5, which is also arranged under a cover layer 6, which, however, need not be transparent, because the cover layer 5 is not like that Cover layer 3, forms 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 a continuous and itself on a longitudinal edge and a front edge slightly tapered deep groove 7 on the inside and an outwardly protruding 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, each panel 1 is one in the deep groove 7 of the same panel provided conical tongue 9 above the there is a wedge-shaped groove 10 into which the wedge-shaped nose 8 is the same Panels 1 fits. Fig. 2 shows how the conical tongue 9 in a groove 7 and the wedge-shaped Nose 8 fit into a wedge-shaped groove 10 belonging to 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 nose 8 is shorter than the depth of the associated groove 10 and each tongue 9 is shorter formed as the depth of the associated groove 7, so that in each groove 7 and 10 a free Room 11 or 12 remains when two panels 1, as shown in FIG. 2, are nested are.

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 in the Drawing shown type is applied to the top 13 of each spring 9 glue. In addition, however, this is not necessary in every case, on the underside 14 of the Spring 9 additional glue can be applied.

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.Two panels 1 are now moved from the position shown in FIG. 1 to that shown in FIG. 2 Put the position together, the top 13 of each spring 9 arrives with the top lying inside 15 of each groove 7 in contact, as well as the bottom 14 of the tongue 9 with the inner side 16 of the wedge-shaped or conical groove 7 in below Contact comes as Fig. 2 shows. The contact areas 17 and 18 are in FIG. 2 to recognize.

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 two panels 1 are plugged together, 13 and, if necessary, on the upper side the underside 14 of each conical spring 9 is glued and evenly distributed over the contact areas 17 and 18. Excess glue can get into the free Rooms 11 and 12 and one on the underside of adjacent panels evade further free space 19. Excess in the free space 12 Glue becomes when putting two panels together on the top 20 each wedge-shaped nose 8 and the inside 21 of each wedge-shaped groove 10 displaced so that an additional gluing in the contact area 22 between the top of the wedge-shaped nose 8 and the wedge-shaped groove 10 is formed.

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, assembled panels 1 also reach above them Lugs 8 and grooves 10 located vertical end faces 23 in contact with one another, see above that gluing also takes place in a contact area 24. excess Glue coming from the contact area 24 onto the surface of the assembled panels 1 emerges, is wiped by the installer after the panels have been plugged together 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.On the underside of the assembled panels 1 there remains an open gap 25, in and through which any excess glue can escape. Here is 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 special double shown in the drawing and described above The tongue and groove connection of the assembled panels 1 is with the aid of glue achieved firm connection between the panels more stable than with simple tongue and groove connections, so that a floor covering laid from the panels 1 also has the necessary stability if the surface is not absolutely flat. Accordingly, there is also no risk that laid from the panels 1 Floor coverings can tear in the area of connection points and thereby resulting cracks moisture can penetrate, resulting in a throw or throw up of the floor covering and thus lead to the destruction of the entire floor can.
