Description

Die Erfindung betrifft eine Einrichtung zum Verbinden von Bodenpaneelen mit einem Kern aus Holzwerkstoff, insbesondere MDF oder HDF, die an einer ersten Seitenkante ein erstes Profil und an der gegenüberliegenden zweiten Seitenkante eine Nut aufweisen, mit einem Verbindungselement, das an einer der ersten Seitenkante des zweiten Bodenpaneels zugewandten Seite ein zum ersten Profil korrespondierendes zweites Profil und an der gegenüberliegenden Seite eine Feder aufweist, die zu der Nut des ersten Bodenpaneels korrespondiert, wobei das Verbindungselement durch Ineingriffbringen des ersten Profils mit dem korrespondierenden zweiten Profil mit dem zweiten Bodenpaneel verbindbar ist.The invention relates to a device for connecting floor panels with a core of wood-based material, in particular MDF or HDF, which have a first profile on a first side edge and a groove on the opposite second side edge, with a connecting element which is on one of the first side edge of the second Floor panel facing side corresponding to the first profile second profile and on the opposite side has a spring corresponding to the groove of the first floor panel, wherein the connecting element by engaging the first profile with the corresponding second profile with the second floor panel is connectable.

Eine derartige Einrichtung zum Verbinden von Bodenpaneelen ist beispielsweise aus der DE 1 963 128 bekannt.Such a device for connecting floor panels is for example from the DE 1 963 128 known.

Eine nur einfach verriegelnde Einrichtung zum Verbinden von Bodenpaneelen ist beispielsweise aus der DE 101 62 275 C1 bekannt.A simple locking device for connecting floor panels is for example from DE 101 62 275 C1 known.

Fußböden aus miteinander verbundenen Bodenpaneelen, insbesondere Laminatfußböden, werden häufig mit dekorativen Elementen oder speziellen Strukturen in der Oberfläche versehen, um eine möglichst naturnahe Anmutung zu erzeugen. Oft soll durch diese Verfahrensweise auch ein bestehendes Produkt besser nachgestellt werden. Bei Booten beispielsweise werden Fugen zwischen Planken mit einem schwarzen teerartigen Material abgedichtet. Dieses erzeugt dann die sogenannte Schiffsbodenoptik. Zur Nachstellung dieser Optik werden beispielsweise Polypropylenleisten auf die Oberseite von Bodenpaneelen in eine vorgefräste Nut eingelegt oder eingeklebt. In der DE 101 62 275 C1 werden zwischen zu verbindendenFloors made of interconnected floor panels, in particular laminate flooring, are often provided with decorative elements or special structures in the surface in order to produce the most natural appearance possible. Often, this procedure should also better readjust an existing product. For example, in boats, joints between planks are sealed with a black tarry material. This then generates the so-called ship bottom optics. To adjust this look, for example, polypropylene strips are inserted or glued to the top of floor panels in a pre-milled groove. In the DE 101 62 275 C1 be connected between

Bodenpaneelen Verbindungselemente angeordnet. Diese sind auf einer Seite mit einer Nut und auf einer gegenüberliegenden Seite mit einer Feder ausgestattet, die zu entsprechenden Nut- und Federprofilen in den Seitenkanten der Bodenpaneele korrespondieren.Floor panels connecting elements arranged. These are equipped on one side with a groove and on an opposite side with a spring, which correspond to corresponding tongue and groove profiles in the side edges of the floor panels.

Dokument DE 101 62 275 C1 offenbart eine Einrichtung die alle Merkmale der Einrichtung gemäß dem Oberbegriff des Anspruchs 1 hat.document DE 101 62 275 C1 discloses a device having all the features of the device according to the preamble of claim 1.

Als Verriegelungselemente sind an den Federn kleine Vorsprünge vorgesehen, die in dafür vorgesehene korrespondierende Ausnehmungen in den Nuten eingreifen und so Bodenpaneel und Verbindungselement miteinander verriegeln. Die an den Federn vorgesehenen Vorsprünge dürfen jedoch eine bestimmte Größe nicht überschreiten, da ansonsten die Federn nicht mehr in die korrespondierenden Nuten eingeführt werden können. Die resultierende Verriegelung ist somit relativ schwach.As locking elements small projections are provided on the springs, which engage in corresponding recesses provided in the grooves and lock so Bodenpaneel and connecting element with each other. However, the projections provided on the springs must not exceed a certain size, since otherwise the springs can no longer be inserted into the corresponding grooves. The resulting lock is thus relatively weak.

Zum Erreichen der gewünschten Optik ist es notwendig, immer zwischen zwei zu verbindenden Paneelen ein Verbindungselement vorzusehen. Es liegt daher nahe, an jeweils eine Seitenkante eines jeden Paneels bereits werkseitig ein Verbindungselement anzuordnen. Aufgrund der relativ schwachen Verriegelung durch die kleinen Verriegelungselemente kann es bei nachfolgenden Fertigungsschritten oder dem Transport der mit den Verbindungselementen versehenen Fußbodenpaneele dazu kommen, dass sich Verbindungselemente von den Paneelen lösen und verloren gehen. Die gewünschte Optik des Fußbodens ist dann nicht mehr zu erreichen.To achieve the desired appearance, it is necessary to always provide a connecting element between two panels to be joined. It therefore makes sense to already arrange a connecting element to one side edge of each panel at the factory. Due to the relatively weak locking by the small locking elements may occur in subsequent manufacturing steps or the transport of the floor panels provided with the connecting elements that detach fasteners from the panels and get lost. The desired appearance of the floor is then no longer achievable.

Aus der GB 2 117 813 A ist eine Einrichtung zum Verbinden von Bodenpaneelen bekannt, bei denen an die den beiden zu verbindenden Paneele jeweils ein Verbindungselement angeordnet wird, die dann miteinander verbindbar sind.From the GB 2 117 813 A a device for connecting floor panels is known in which a respective connecting element is arranged on the two panels to be connected, which are then connectable to each other.

Auch aus der NL 1 027 256 C1 ist eine Einrichtung zum Verbinden von Bodenpaneelen bekannt, bei der ein Verbindungselement zwischen zwei zu verbindenden Bodenpaneelen angeordnet wird.Also from the NL 1 027 256 C1 a device for connecting floor panels is known in which a connecting element between two floor panels to be joined is arranged.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Einrichtung zum Verbinden eines ersten Bodenpaneels mit einem zweiten Bodenpaneel dahingehend zu verbessern, dass die Verriegelung zwischen zweiten Bodenpaneel und Verbindungselement verstärkt wird.The invention is therefore based on the object to improve a device for connecting a first floor panel with a second floor panel to the effect that the lock between the second floor panel and connecting element is reinforced.

Die Erfindung löst die gestellte Aufgabe durch eine Einrichtung mit den Merkmalen des kennzeichnenden Teils des Anspruchs 1, wobei des Verbindungselement und das zweite Bodenpaneel in horizontalen Richtung doppelt verriegelbar sind, und wobei das Verbindungselement aus Aluminium oder Kupfer besteht. Dadurch werden weitere dekorative Ausgestaltungen eines fertig verlegten Fußbodens möglich.The invention achieves the stated object by a device having the features of the characterizing part of claim 1, wherein the connecting element and the second floor panel in the horizontal direction are double-locked, and wherein the connecting element made of aluminum or copper. As a result, further decorative designs of a finished floor are possible.

Durch diese Ausgestallung ist sichergestellt, dass sich das zweite Bodenpaneel und das Verbindungselement nicht versehentlich, beispielsweise bei nachfolgenden Produktions- oder Verpackungsschritten, im Werk des Herstellers voncinander lösen können. Dem Verbraucher werden somit nur Bodenpaneele verkauft, an deren einer Seitenkante sich bereits ein Verbindungselement befindet. Somit ist sichergestellt, dass die gewünschte Optik des Fussbodens einfach und schnell zu erreichen ist.This configuration ensures that the second floor panel and the connecting element can not be accidentally detached from one another, for example during subsequent production or packaging steps, at the manufacturer's factory. The consumer thus only floor panels are sold, at one side edge is already a connecting element. This ensures that the desired look of the floor can be achieved easily and quickly.

Besonders vorreilhafterweiser ist das Verbindungselement und das zweite Bodenpaneel auch in vertikaler Richtung verriegelbar. Damit ist gewährleistet, dass sich auch in einer Richtung senkrecht zur Verlegeebene der zu verbindenden Bodenpaneele das Verbindungselement nicht vom zweiten Bodenpaneel lösen kann.Particularly vorreilhaftweiser the connecting element and the second floor panel can be locked in the vertical direction. This ensures that even in a direction perpendicular to the laying plane of the floor panels to be joined, the connecting element can not be detached from the second floor panel.

Vorteilhafterweise weist die Nut des ersten Bodenpaneels wenigstens ein Verriegelungselement und die Feder des Verbindungselementes wenigstens ein zu diesem Verriegelungselement korrespondierendes Verriegelungselement auf. Zum Verbinden verschiedener Bodenpaneele wird die Feder des Verbindungselementes, das an einer Seitenkante eines der beiden Bodenpaneele angeordnet ist, in die Nut des anderen Bodenpaneels eingeführt. Dadurch, dass sowohl Feder als auch Nut über zueinander korrespondierende Verriegelungselemente verfügen, ist sichergestellt, dass auch die Verhindung der beiden Bodenpaneele über das Verbindungselement nicht einfach gelöst werden kann.Advantageously, the groove of the first floor panel has at least one locking element and the spring of the connecting element has at least one locking element corresponding to this locking element. For connecting various floor panels, the spring of the connecting element, which is arranged on a side edge of one of the two floor panels, is inserted into the groove of the other floor panel. The fact that both spring and groove have mutually corresponding locking elements, it is ensured that the Verhindung the two floor panels on the connecting element can not be easily solved.

Vorteilhafterweise ist das Verriegelungselement der Feder des Verbindungselementes als ein Hakenelement und das Verriegelungselement der Nut des ersten Bodenpaneels als eine korrespondierende Ausnehmung ausgeslaltet. Durch diese einfach herzustellende Ausgestaltung ist sichergestellt, dass verschiedene Bodenpaneele über das Verbindungselement einfach miteinander verbunden werden können.Advantageously, the locking element of the spring of the connecting element is exposed as a hook element and the locking element of the groove of the first floor panel as a corresponding recess. By this simple to manufacture design ensures that various floor panels can be easily connected to each other via the connecting element.

Wenn beide Bodenpaneele durch das Verbindungselement sowohl in vertikaler Richtung als auch in horizontaler Richtung verriegelbar sind, ist gewährleistet, dass sich über das Verbindungselement verbundene Bodenpaneele nicht einfach voneinander lösen können, wenn sie der großen Belastung eines Fußbodens durch Begehen ausgesetzt sind. Insbesondere bei auf unebenen Unterlagen verlegten Fußböden können hier enorme Belastungen auftreten.If both bottom panels are locked by the connecting element in both the vertical direction and in the horizontal direction, it is ensured that Floor panels connected by the connector can not easily disengage from each other when subjected to the heavy load of a floor by walking. Particularly in floors laid on uneven surfaces, enormous loads can occur here.

Das zweite Profil weist ein oberes Hakenelement und ein unteres Hakenelement auf, die in eine dafür vorgesehene obere Ausnehmung und eine untere Ausnehmung im ersten Profil eingreifen. Jedes Hakenelement sorgt dabei beim Eingreifen in die korrespondierende Ausnehmung dafür, dass eine horizontale Verriegelung zwischen Verbindungselement und zweitem Bodenpaneel entsteht.The second profile has an upper hook element and a lower hook element, which engage in a designated upper recess and a lower recess in the first profile. Each hook element ensures when engaging in the corresponding recess that a horizontal locking between the connecting element and the second floor panel is formed.

Die Oberseite des oberen Hakenelementes schließt mit der Oberseite der verbundenen Bodenpaneele plan ab. Dadurch ist gewährleistet, dass der dekorative Effekt des Verbindungselementes voll zur Geltung kommt, ohne dass Stufen oder Kanten im fertig verlegten Fußboden auftreten. Somit wird ein gefahrloses und bequemes Begehen des Fußbodens ermöglicht. Besonders vorteilhaft ist, dass dadurch weniger Fräsverluste an den dekorierten und beschichteten Holzwerkstoffplatten entstehen. Vorzugsweise weist das obere Hakenelement und/oder das untere Hakenelement eine Dicke zwischen 0,7 mm und 1,4 mm auf. Dadurch, dass Bodenpaneel und Verbindungselement doppelt verriegelbar sind und somit auch die beim Begehen auftretenden Belastungen auf zwei Verriegelungspunkte verteilt werden, sind deutlich geringere Materialstärken als bei herkömmlichen Verbindungselementen möglich.The top of the upper hook element is flush with the top of the connected floor panels. This ensures that the decorative effect of the connecting element is fully effective, without steps or edges occur in the finished floor. Thus, a safe and comfortable walking on the floor is possible. It is particularly advantageous that less milling losses occur on the decorated and coated wood-based panels. Preferably, the upper hook element and / or the lower hook element has a thickness between 0.7 mm and 1.4 mm. The fact that the floor panel and connecting element are double lockable and thus also the loads occurring when walking on two locking points are distributed, significantly lower material thicknesses than conventional fasteners are possible.

Das obere Hakenelement und das untere Hakenelement sind insbesondere kürzer ausgebildet als die Feder des Verbindungselementes.The upper hook element and the lower hook element are in particular shorter than the spring of the connecting element.

Vorzugsweise sind das erste Profil und das zweite Profil symmetrisch zu einer Ebene ausgestaltet, die parallel zu einer Oberseite und einer Unterseite der Bodenpaneele verläuft. Diese Ausgestaltung hat mehrere Vorteile. Zum einen ist die Herstellung der Profile sehr einfach. Insbesondere das an einer Seitenkante des Bodenpaneels angeordnete Profil wird beispielsweise durch Fräsen aus dem Holzwerkstoffkern des Bodenpaneels herausgearbeitet.Preferably, the first profile and the second profile are configured symmetrically to a plane which runs parallel to an upper side and a lower side of the floor panels. This embodiment has several advantages. For one, the production of the Profiles very easy. In particular, the arranged on a side edge of the floor panel profile is worked out, for example, by milling from the wood material core of the floor panel.

Zum anderen führt die erfindungsgemäße Ausgestaltung des Profils dazu, dass beispielsweise das obere Hakenelement von oben in die dafür vorgesehene obere Ausnehmung des Profils eingreift, während das untere Hakenelement von unten in die dafür vorgesehene untere Ausnehmung im ersten Profil eingreift. Es kommt somit zu einer ohne Werkzeug unlösbaren Verbindung zwischen zweitem Bodenpaneel und Verbindungselement. Dadurch werden die Stärke der Verriegelung und die Verbindungssicherheit zwischen zweitem Bodenpaneel und Verbindungselement weiter erhöht.On the other hand, the inventive design of the profile causes, for example, the upper hook element engages from above into the designated upper recess of the profile, while the lower hook element engages from below into the designated lower recess in the first profile. There is thus a non-detachable connection between the second floor panel and connecting element. As a result, the strength of the lock and the connection security between the second floor panel and connecting element are further increased.

Vorteilhafterweise ist das Verbindungselement streifenförmig. Die sichtbare Breite des Verbindungselementes ist somit gegenüber seiner Länge, die sich über die gesamte Seitenkante der zu verbindenden Bodenpaneele erstreckt, gering, so dass die Sichtfuge gegenüber der Ausdehnung der Paneele schmal ist.Advantageously, the connecting element is strip-shaped. The visible width of the connecting element is thus small compared to its length, which extends over the entire side edge of the floor panels to be joined, so that the visual joint is narrow compared to the extent of the panels.

Die Oberseite des Verbindungselementes kann konturiert sein. Dadurch sind verschiedene Ausgestaltungen der Sichtfuge und somit verschiedene dekorative Effekte möglich. Die Kontur der Oberseite ist beispielsweise konkav oder konvex ausgeformt.The top of the connecting element can be contoured. As a result, various embodiments of the visual joint and thus various decorative effects are possible. The contour of the upper side is, for example, concave or convex.

Auch eine im Querschnitt im Wesentlichen V-förmige Kontur ist dabei denkbar.A cross-sectionally substantially V-shaped contour is also conceivable.

Insbesondere ist das Verbindungselement länger als die zu verbindenden Seitenkanten der Bodenpaneele. Damit können auch mehrere Bodenpaneele nebeneinander mit ein und demselben Verbindungselement verbunden werden. Dadurch wird die Verbindung nicht benachbarter Bodenpaneele untereinander gestärkt. Ein derart langes Verbindungselement hat folglich eine größere Stabilität des verlegten Fußbodens zur Folge.In particular, the connecting element is longer than the side edges of the floor panels to be joined. This also several floor panels can be connected side by side with one and the same connection element. As a result, the connection of non-adjacent floor panels is strengthened with each other. Such a long connecting element consequently results in greater stability of the laid floor.

Vorteilhafterweise weist die Feder des Verbindungselementes eine Dicke zwischen 0,7 mm und 1,4 mm auf. Auf diese Weise kann Material eingespart werden, ohne die Stabilität der Verbindung zu schwächen. Somit werden die Materialkosten und damit die Herstellungskosten gesenkt.Advantageously, the spring of the connecting element has a thickness of between 0.7 mm and 1.4 mm. In this way, material can be saved without weakening the stability of the connection. Thus, the material costs and thus the production costs are reduced.

Dadurch ist das Verbindungselement 20 mit dem zweiten Paneel 10 verbunden und sowohl in horizontaler Richtung als auch in vertikaler Richtung verriegelt. Wie die Figuren erkennen lassen, umgreift das zweite Profil 24 nahezu vollständig das erste Profil 14 und die Hakenelemente 26, 28 stützen sich in den Ausnehmungen 16, 18 in horizontaler Richtung beidseitig ab.The upper hook element 26 engages in the upper recess 16 of the first profile 14 and the lower hook element 28 in the lower recess 18 a. Thereby, the connecting member 20 is connected to the second panel 10 and locked in both the horizontal direction and in the vertical direction. As the figures show, the second profile 24 almost completely surrounds the first profile 14 and the hook elements 26, 28 are supported in the recesses 16, 18 in the horizontal direction on both sides.

Die Feder 22 des Verbindungselementes 20 wird in die dafür vorgesehene Nut 4 in der zweiten Seitenkante 2 des ersten Bodenpaneels 1 eingeführt. Die Feder 22 weist an ihrem äußersten Ende ein nach oben gerichtetes Hakenelement 30 auf. In Figur 1 a ist der erste Teil des Verbindens zweier Bodenpaneele 1, 10 über das Verbindungselement gezeigt. Das zweite Bodenpaneel 10 wird dabei leicht schräg an das erste Bodenpaneel 1 herangeführt, und die Feder 22 des Verbindungselementes 20 in die dafür vorgesehene Nut 4 im ersten Bodenpaneel 1 eingeführt.The spring 22 of the connecting element 20 is inserted into the groove 4 provided in the second side edge 2 of the first floor panel 1. The spring 22 has an upwardly directed hook element 30 at its outermost end. In FIG. 1 a is the first part of connecting two floor panels 1, 10 shown over the connecting element. The second floor panel 10 is thereby introduced slightly obliquely to the first floor panel 1, and the spring 22 of the connecting element 20 is inserted into the groove 4 provided in the first floor panel 1.

In Figur 1b ist es bereits zum Kontakt zwischen dem Verbindungselement 20 und dem ersten Bodenpaneel 1 gekommen. Zum Verbinden der beiden Bodenpaneele 1, 10 miteinander wird im Anschluss an die in Figur 1b gezeigte Situation das zweite Paneel 10 abwärts geschwenkt. Dabei greift das Hakenelement 30 in der Feder 22 des Verbindungselementes 20 in die Ausnehmung 8 am Grund der Nut 4 ein. Es kommt dadurch auch zu einer Verriegelung des ersten Bodenpaneels 1 mit dem Verbindungselement 20 sowohl in vertikaler Richtung als auch in horizontaler Richtung.In FIG. 1b it has already come to the contact between the connecting element 20 and the first floor panel 1. To connect the two floor panels 1, 10 together after the in FIG. 1b shown situation, the second panel 10 is pivoted downward. In this case, the hook element 30 engages in the spring 22 of the connecting element 20 in the recess 8 at the bottom of the groove 4 a. It also comes to a locking of the first floor panel 1 with the connecting element 20 both in the vertical direction and in horizontal Direction.

Diese Situation ist in Figur 1c gezeigt. Die beiden Paneele 1, 10 sind über das Verbindungselement 20 miteinander verbunden. Sowohl das erste Bodenpaneel 1 als auch das zweite Bodenpaneel 2 sind mit dem Verbindungselement 20 sowohl in vertikaler Richtung als auch in horizontaler Richtung verriegelt. Die Dicke des oberen Hakenelementes 26 und/oder des unteren Hakenelementes 28 senkrecht zu der Vertegechene der Bodenpaneele 1, 10 beträgt zwischen 0,7 mm und 1.4 mm. Auch die Dicke der Feder 22 des Verbindungselementes 20 senkrecht zu der Verlegeebene der Bodenpaneele beträgt zwischen 0,7 mm und 1,4 mm.This situation is in Figure 1c shown. The two panels 1, 10 are connected to each other via the connecting element 20. Both the first floor panel 1 and the second floor panel 2 are locked to the connecting member 20 in both the vertical direction and the horizontal direction. The thickness of the upper hook element 26 and / or the lower hook element 28 perpendicular to the vertices of the floor panels 1, 10 is between 0.7 mm and 1.4 mm. The thickness of the spring 22 of the connecting element 20 perpendicular to the laying plane of the floor panels is between 0.7 mm and 1.4 mm.
