Description

Die vorliegende Erfindung betrifft ein Verbindungselement gemäss Oberbegriff von Anspruch 1 sowie Paneele zur Bildung eines Fussbodenbelages nach Anspruch 6.The present invention relates to a connecting element according to Preamble of claim 1 and panels to form a Floor covering according to claim 6.

Ein Fussbodenbelag kann beispielsweise durch flächiges Aneinanderfügen von im wesentlichen rechteckförmigen Paneelen gebildet werden. Derartige Paneelen können beispielsweise aus harten Fussbodenpaneelen wie beispielsweise Laminatpaneelen, Furnierparkett, Fertigparkett oder anderen ausgebildet sein.A floor covering can, for example, be joined together by a flat surface formed by essentially rectangular panels become. Such panels can for example be made of hard Floor panels such as laminate panels, veneer parquet, Ready parquet or other be formed.

Die einzelnen Paneele weisen herkömmlicherweise häufig an den Seiten Nuten resp. Federn auf, mit welchen sie untereinander formschlüssig verbunden werden können. Die kraftschlüssige Verbindung der Paneelen kann im wesentlichen auf zwei Arten erfolgen, nämlich indem die Paneelen jeweils mit dem Untergrund verleimt resp. sonstwie verbunden werden oder indem die Paneelen miteinander verleimt werden, vorzugsweise über die Nut-Feder-Verbindung, oder mittels formschlüssiger Verbindungselemente miteinander verbunden werden. Im zweiten Fall, wenn die Paneelen nur lose auf dem Untergrund aufliegen, wird auch häufig von schwimmendem oder schwebendem Parkett gesprochen.The individual panels traditionally point to the Side grooves respectively. Springs with which they are among themselves can be positively connected. The positive connection the panels can be done essentially in two ways, namely by gluing the panels to the substrate resp. otherwise be connected or by the panels are glued together, preferably via the tongue and groove connection, or by means of positive connection elements be connected to each other. In the second case, when the panels only lying loosely on the surface is also often caused by floating or floating parquet.

Der Vorteil des schwimmenden oder schwebenden Parketts liegt unter anderem darin, dass durch diese Fertigungsweise allfällige temperatur- und feuchtigkeitsbedingte Schrumpf- resp. Ausdehnungsbewegungen aufgefangen werden können und nicht zu Spannungen führen, wie dies bei verleimtem Parkett auftreten kann. The advantage of floating or floating parquet lies among other things in the fact that any possible temperature and humidity-related shrinkage resp. Expansion movements can be absorbed and not to tension lead, as can occur with glued parquet.

Bei der schwimmenden resp. schwebenden Verlegung der Paneelen besteht nun das Problem, dass sich die einzelnen Paneelen beim Schrumpfen resp. Ausdehnen untereinander verschieben, wodurch unerwünschte Fugen zwischen den Paneelen entstehen können. Dies kann auch beim Einsatz von Leim als Verbindungsmittel geschehen, indem die Leimstelle aufbricht, beispielsweise bei Feuchtigkeitseinfluss.With the floating resp. floating laying of the panels there is now the problem that the individual panels at Shrink or Extend among themselves, whereby unwanted joints between the panels can arise. This can also happen when using glue as a lanyard, by breaking up the glue point, for example when exposed to moisture.

Um dieser Gefahr zu begegnen sind nun Verbindungstechniken bekannt, bei welchen mittels speziellen Verbindungsmitteln die einzelnen Paneele untereinander zusammengehalten werden.In order to counter this danger, connection techniques are now known, where with special lanyards the individual panels are held together.

So ist beispielsweise aus der DE 297 10 175 ein Fussbodenbelag bekannt, welcher aus harten Fussbodenpaneelen gebildet wird, welche als formschlüssig zusammenwirkende Kupplungsteile ausgebildete Federn und Nuten aufweisen. Diese sind in der Form derart ausgestaltet, dass sie jeweils gleichzeitig als integrierte Verriegelungsmittel dienen. Diese derart ausgebildeten Federn resp. Nuten in den Seitenkanten der Paneelen sind allerdings nur mit speziellen Werkzeugen zu formen und müssen einen hohen Genauigkeitsgrad aufweisen. Damit sind diese Bereiche sehr empfindlich auf Beschädigungen, was sowohl beim Transport und Lagerung wie auch beim Verlegen entsprechende Sorgfalt in der Handhabung verlangt. Die im genannten Dokument dargestellte Ausführung vermag zwar mittlere Kräfte senkrecht zur Verbindungsrichtung der einzelnen Paneelen aufnehmen, bei grösseren Kräften besteht allerdings die Gefahr, dass die Verbindung aufgebrochen werden kann. In Längsrichtung wird allerdings nur eine beschränkte Verschiebung der Paneelen untereinander ermöglicht, da die Verbindung über die gesamte Länge der Paneelen erfolgt und damit der Verschiebung in dieser Richtung Widerstand entgegensetzt. Dies kann zu Problemen bei der Verlegung der Paneelen führen, welche in Längsrichtung sehr genau ausgerichtet verlegt werden müssen, damit möglichst keine Längskorrektur der Ausrichtung erforderlich ist.For example, from DE 297 10 175 is a floor covering known, which is formed from hard floor panels, which designed as form-fitting interacting coupling parts Have tongues and grooves. These are in the form designed to be integrated at the same time Serve locking means. These springs designed in this way resp. There are grooves in the side edges of the panels to mold only with special tools and must have a high Show degree of accuracy. This makes these areas very sensitive for damage, both during transport and storage as with appropriate care in laying Handling requires. The presented in the mentioned document Execution is capable of medium forces perpendicular to the direction of connection of the individual panels, for larger ones Forces, however, run the risk of breaking the connection can be. In the longitudinal direction, however, only one limited displacement of the panels with each other enables because the connection runs the entire length of the panels takes place and thus the shift in this direction resistance opposed. This can cause problems when laying of the panels, which are very precisely aligned in the longitudinal direction must be installed so that there is no longitudinal correction if possible alignment is required.

Die Aufgabe der vorliegenden Erfindung bestand nun darin, ein Verbindungsmittel für derartige Paneelen zu finden, welches einfach herzustellen und anzuwenden ist, eine zuverlässige Verriegelung senkrecht zur Verbindungakante benachbarter Paneelen ermöglicht und gleichzeitig die Längsverschiebbarkeit benachbarter Paneelen nicht wesentlich einschränkt.The object of the present invention was now a To find connecting means for such panels, which easy to manufacture and use, reliable locking perpendicular to the connection edge of adjacent panels enables and at the same time the longitudinal displacement of neighboring Panels are not significantly restricted.

Diese Aufgabe wird erfindungsgemäss durch ein Verbindungselement mit den Merkmalen nach Anspruch 1 gelöst resp. von Fussbodenpaneelen nach Anspruch 6. Bevorzugte Ausführungsformen der Erfindung ergeben sich aus den abhängigen Ansprüchen 2 bis 5 resp. 7 bis 10.According to the invention, this object is achieved by a connecting element solved with the features of claim 1. of floor panels according to claim 6. Preferred embodiments of the Invention result from the dependent claims 2 to 5 resp. 7 to 10.

Die erfindungsgemäss ausgebildeten Verbindungselemente lassen sich einmal sehr einfach und kostengünstig herstellen. Danach lassen sich die Verbindungselemente vorzugsweise jeweils an einer Seite eines Paneels voneinander beabstandet vormontieren, indem jeweils die seitlichen Zungen einer Seite in die entsprechende Nut der Paneele eingeschoben wird und mit der mittleren Zunge des Verbindungselementes, welche mit dem Rand der Unterseite der Paneele in Verbindung gebracht wird. Die derart vorbereiteten Paneelen lassen sich am Boden ausrichten und anschliessend die benachbarte Paneele, welche an der gegenüberliegenden Seite ebenfalls vorteilhafterweise bereits mit Verbindungselementen ausgestattet worden ist, über die Nut-Kamm-Verbindung anfügen und die Zunge resp. Zungen des nun noch freien Endes des Verbindungselementes in die Nut dieser Paneele einklinken.Leave the connecting elements designed according to the invention produce yourself very easily and inexpensively. After that the connecting elements are preferably each on one Pre-assemble the side of a panel at a distance from each other, by moving the side tongues of one side into the corresponding one Groove of the panels is inserted and with the middle Tongue of the connecting element, which with the edge of the bottom the panels are associated. The so prepared Panels can be aligned on the floor and then the adjacent panels, which are on the opposite Side also advantageously already with connecting elements has been equipped via the groove-comb connection add and the tongue respectively. Tongues of the now free end of the connecting element in the groove of these panels latch.

Durch die vorzugsweise geneigte Ausführung der Zungen wird eine Feder- resp. Spannwirkung im Zusammenwirken mit den entsprechenden Nuten erreicht. Durch die vorteilhafte Ausbildung der Verbindungselemente mit mindestens einer mittleren Zunge wird nun vorteilhafterweise ein Verkanten des Verbindungselementes auch beim seitlichen Verschieben von benachbarten Paneelen wirkungsvoll verhindert. Damit ist es möglich, nach der Verlegung und Zusammenfügen von benachbarten Paneelen diese entlang ihrer Verbindungskante zu verschieben.Due to the preferably inclined design of the tongues Spring resp. Tension in interaction with the corresponding Grooves reached. Due to the advantageous training of Fasteners with at least one middle tongue now advantageously tilting the connecting element also effective when moving adjacent panels to the side prevented. It is possible after laying and joining adjacent panels along these To move the connecting edge.

Ebenfalls erlaubt diese Verbindungsart die Längsverschiebung von Paneelen untereinander, welch durch Dehn- resp. Schrumpfvorgänge hervorgerufen werden, ohne dass damit die Verbindung durch übermässige Spannungen zerstört würde oder dass Spannungen in der Paneelen selbst aufgebaut würden.This type of connection also allows longitudinal displacement of panels with each other, which by expansion or. Shrinking processes are caused without the connection would be destroyed by excessive tension or that tension in which the panels themselves would be built.

Die erfindungsgemäss vorgestellte Verbindungslösung erlaubt somit vorteilhafterweise eine zuverlässige, haltbare, kostengünstige und einfach zu erstellende Verbindung von Paneelen zur Bildung eines Fusebodenbelages, insbesondere eines schwimmenden resp. schwebenden Fussbodenbelages.The connection solution presented according to the invention thus allows advantageously a reliable, durable, inexpensive and easy to connect panels to the Formation of a floor covering, in particular a floating one resp. floating flooring.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand von Zeichnungen noch näher erläutert. Es zeigen

  • Fig. 2 den Querschnitt durch die erfindungsgemässe Verbindung von zwei Paneelen zur Bildung eines Fussbodenbelages mit erfindungsgemässem Verbindungselement;
  • Fig. 3 die Aufsicht auf ein erfindungsgemässes Verbindungselement; und
  • Fig. 4 die Ansicht eines mit einem erfindungsgemässen Verbindungselement ausgerüsteten Paneels.
    • An embodiment of the invention is explained in more detail below with reference to drawings. Show it
  • 1 shows the view of two conventional panels for forming a floor covering.
  • 2 shows the cross section through the connection according to the invention of two panels to form a floor covering with the connection element according to the invention;
  • 3 shows the top view of a connecting element according to the invention; and
  • 4 shows the view of a panel equipped with a connecting element according to the invention.

    • Fussbodenbeläge können in bekannter Weise durch aneinanderfügen von Paneelen 1, welche mit Nut 2 und Feder 3 als Kupplungselemente versehen sind, gebildet werden, wie schematisch in Figur 1 dargestellt. Die Paneelen 1 können dabei entweder mit dem Untergrund verbunden wie beispielsweise verleimt werden. Häufig wird dabei auch die Nut-Feder-Verbindung durch eine Verleimung ergänzt.Floor coverings can be joined together in a known manner of panels 1, which with groove 2 and tongue 3 as coupling elements are provided, are formed, as schematically in Figure 1 shown. The panels 1 can either with the underground connected such as glued. Frequently the tongue and groove connection is also achieved by gluing added.

    Wenn der Fussbodenbelag als sogenannt schwimmender oder schwebender Belag ausgeführt werden soll, d.h. nur auf dem Untergrund aufliegt und nicht mit diesem verbunden ist, müssen die Paneelen untereinander kraftschlüssig verbunden werden. Dies kann beispielsweise allein durch die mit einer Verleimung versehenen Nut-Feder-Verbindung erfolgen. Dabei besteht allerdings die Gefahr, dass beim unterschiedlichen Ausdehnen resp. Schrumpfen der einzelnen Paneelen und der damit verbundenen Spannung in der Verbindung die Verleimung aufreisst und damit ein störender Spalt zwischen den betroffenen Paneelen entsteht.If the floor covering is so-called floating or floating To be executed, i.e. only on the ground rests and is not connected to it, the Panels are non-positively connected to each other. This can, for example, only be provided with a glue Tongue and groove connection. However, there is the risk that different expansion or. Shrinking of the individual panels and the associated ones Tension in the connection tears open the glue and with it a disruptive gap is created between the affected panels.

    Um dies zu verhindern und überdies eine sofort haltbare Verbindung auf einfache Weise zu realisieren, können anstelle der Verleimung mechanische Verbindungs- resp. Verriegelungshilfen eingesetzt werden. Erfindungsgemäss wird hierfür die Verwendung eines Verbindungselementes 4 vorgeschlagen, wie dies im Querschnitt in Figur 2 dargestellt ist.To prevent this and also an immediately durable connection can be easily realized instead of Gluing mechanical connection resp. Locking aids be used. According to the invention, this is used proposed a connecting element 4, as in cross section is shown in Figure 2.

    Die miteinander zu verbindenden Paneelen 1 und 1' weisen wiederum ein Feder 3 resp. eine Nut 2' auf, welche eine formschlüssige, längsverschiebbare Verbindung der Paneelen bilden. Quer zur Verbindungekante der Paneelen 1 resp. 1' wird nun das mit Zungen 5,6,7 ausgestattete Verbindungselement 5 in entsprechend ausgebildete Nuten 8,9 resp. gebildeten Schlitz 10 in der Unterseite der Paneelen 1,1' eingesetzt.The panels 1 and 1 'to be connected to one another in turn point a spring 3 resp. a groove 2 'on which a form-fitting, form a longitudinally displaceable connection of the panels. Transversely to the connecting edge of the panels 1 and 1 'is now equipped with tongues 5,6,7 connecting element 5 in accordingly trained grooves 8.9 respectively. formed slot 10 in the Bottom of the panels 1,1 'inserted.

    Die beiden Zungen 5 und 6 greifen dabei in die Nut 8 des Paneels 1, resp. in den zwischen Paneel 1 und 1' gebildeten Schlitz 10 ein. Die Zunge 7 greift in die in Paneel 1' ausgebildeten Nut 9 ein und schafft damit eine quer zur Verbindungskante der beiden Paneelen 1 und 1' wirkende zuverlässige Verriegelung.The two tongues 5 and 6 engage in the groove 8 of the panel 1, resp. in the formed between panel 1 and 1 ' Slot 10 a. The tongue 7 engages in the panel 1 ' Groove 9 and creates a transverse to the connecting edge of the two panels 1 and 1 'acting reliable locking.

    Das Verbindungselement 4 ist in Figur 3 noch in der Aufsicht dargestellt, woraus die bevorzugte Gestaltung der Grundfläche 4' des Verbindungselementes 4 in Y-Form mit parallelen Seitenkanten klar ersichtlich ist. Die Zunge 5 ist dabei in zwei einzelne Zungen 5 resp. 5' aufgeteilt, ebenso die Zunge 6 in zwei in einer Linie angeordneten Zungen 6 resp. 6'. Diese Anordnung ergibt nun eine stabile Verbindung mit dem Paneel 1, welche auch bei einer Längsverschiebung der beiden Paneele 1 und 1' untereinander nicht verkanten kann. Damit bleiben die Zungen 5,5' resp. 6,6' resp. 7 jeweils immer parallel in den entsprechenden Nuten 8,9 resp. Spalt 10 der Paneelen 1 resp. 1' angeordnet und lassen eben diese Längsverschiebung unter Beibehaltung einer wirkungsvollen Verriegelung der beiden Paneelen 1 resp. 1' senkrecht zu ihren Verbindungskanten.The connecting element 4 is still in supervision in Figure 3 shown, from which the preferred design of the base area 4 'of the connecting element 4 in Y-shape with parallel side edges is clearly evident. The tongue 5 is divided into two Tongues 5 resp. 5 'divided, as well as the tongue 6 in two tongues arranged in a line 6 respectively. 6 '. This arrangement now results in a stable connection with the panel 1, which even with a longitudinal displacement of the two panels 1 and 1 ' cannot tilt with each other. That leaves the tongues 5.5 'resp. 6.6 'resp. 7 always in parallel in the corresponding Grooves 8.9 resp. Gap 10 of the panels 1 respectively. 1 'arranged and just keep this longitudinal shift effective locking of the two panels 1 resp. 1 'perpendicular to their connecting edges.

    Vorteilhafterweise ist das Verbindungselement 4 aus Federstahl hergestellt, was insbesondere zur guten Klemmeigenschaft des Verbindungselementes 4 beiträgt.The connecting element 4 is advantageously made of spring steel manufactured, which in particular to the good clamping property of Connecting element 4 contributes.

    In Figur 4 ist nun noch die Ansicht eines Paneels 1 mit eingesetztem Verbindungselement 4 dargestellt. Derart vorbereitet können nun die Paneele 1 resp. 1' einfach miteinander verbunden werden. Die Abstände der Verbindungselemente 4 können entsprechend dem Einsatzzweck des zu bildenden Fussbodens frei gewählt werden.In Figure 4 is still the view of a panel 1 with inserted Connection element 4 shown. So prepared can now panels 1 respectively. 1 'simply connected to each other become. The distances between the connecting elements 4 can be corresponding the purpose of the floor to be formed is chosen freely become.

    Selbstverständlich kann die Formgebung des Verbindungselementes 4 von der in der Zeichnung dargestellten Form abweichen, entscheidend ist der Einsatz von drei Zungen in drei parallel angeordneten Nuten resp. Schlitzen. So könnte der Schlitz 10 beispielsweise auch durch eine zusätzliche Nut im Paneel 1 gebildet sein, wodurch die Verbindungsnaht zwischen den zwei benachbarten Paneelen 1 resp. 1' geschlossen bliebe.Of course, the shape of the connecting element 4 differ from the shape shown in the drawing, crucial is the use of three tongues in three arranged in parallel Grooves respectively Slits. For example, slot 10 could also formed by an additional groove in panel 1 be, creating the joint between the two neighboring ones Panels 1 resp. 1 'would remain closed.
