Description

Die Erfindung betrifft ein Paneel, insbesondere ein Fussbodenpaneel, das zumindest an einer seiner Seiten eine Feder und an der gegenüberliegenden Seite eine Nut aufweist, die so ausgebildet sind, dass mehrere Paneele durch Ineinanderstecken miteinander verbindbar sind, wobei die Feder-/Nut-Verbindung mit Verrastmitteln versehen ist, die ein Verschieben zweier Paneele entgegen der Verbindungsrichtung verhindern. The invention relates to a panel, in particular a floor panel, which has at least on one of its sides, a spring and on the opposite side a groove which are designed so that several panels can be connected together by plugging into one another, wherein the spring / groove connection with latching means is provided, which prevent a displacement of two panels opposite to the connection direction.

Derartige Paneele sind beispielsweise in der WO97/47834 und der JP 3-169967 offenbart. Such panels are, for example, in WO97 / 47834 and JP 3-169967 disclosed. Solche Paneele lassen sich miteinander verbinden, ohne dass sie zum Beispiel auf dem Untergrund verklebt oder miteinander durch zusätzliche Verbindungsglieder verbunden werden müssen. Such panels can be interconnected without having to be glued, or for example on the ground connected together by additional links. Die Verbindungskanten zweier Fussbodenpaneele können durch geradliniges Ineinanderschieben parallel zum Untergrund ineinandergesteckt werden, wobei durch Formschluss der Verrastmittel ein Verschieben der Paneele entgegen der Verbindungsrichtung ausgeschlossen wird. The connecting edges of two floor panels can be inserted into each other parallel to the ground by linear telescoping wherein is excluded counter to the direction of connection by positive fit to the latching means a displacement of the panels. Die entsprechende Ausbildung der Feder/Nut wird Klick-Profil genannt. The corresponding design of the spring / groove is called Click-profile. Damit der Formschluss zwischen den Verrastmitteln eintreten kann, verbiegt beim Ineinanderstecken zweier Paneele die Feder des ersten Paneels die Unterlippe der Nut des zweiten Paneels in Richtung der Unterseite. Thus, the fit between the latching means can occur, the spring of the first panel bends the lower lip of the groove of the second panel toward the bottom during plugging together of two panels. Kommen die Verrastmittel zueinander in Überdeckung, federt die Unterlippe elastisch zurück und stellt den Formschfuss her. The latching means coming to each other in covering, cushions the lower lip elastic and restores the Formschfuss forth.

Solche Paneele sind in aller Regel aus Holzwerkstoffen, insbesondere HDF oder MDF hergestellt. Such panels are made usually from wood materials, in particular HDF or MDF. Das Elastizitätsverhalten der Unterlippe ist deshalb nicht exakt einstellbar. The elastic behavior of the lower lip is therefore not exactly set. Insbesondere bei nicht fachgerechtem Ineinanderstecken zweier Paneele kann nicht ausgeschlossen werden, dass die Unterlippe zu weit verbogen wird und dabei bricht, was beim Verlegen nicht unbedingt erkannt wird, aber zu keiner oder einer schlechten Verrastung führt. Especially with inexpert fitting together of two panels can not be excluded that the lower lip is bent too far and it breaks, which is not necessarily detected during installation, but results in no or poor latching.

Aus der WO 94/01628 sind Verbindungselemente für Bodenpaneele bekannt, die auf der Unterseite mit den Paneelen verbunden werden und eine Schnappverbindung ermöglichen. From WO 94/01628 are known connecting elements for floor panels, which are connected on the underside with the panels and provide a snap connection. An dem einen Verbindungselement ist eine Nut und an dem anderen Verbindungselement eine Feder ausgebildet. At the one connecting element has a groove and at the other connecting element is a spring is formed. Die Feder des Verbindungselementes ist geschlitzt, so dass zwei zueinander elastische Lippen ausgebildet werden. The spring of the connecting element is slotted so that two mutually resilient lips are formed. Jede Lippe ist mit einem keilförmigen Absatz versehen. Each lip is provided with a wedge-shaped shoulder. Die Nut des anderen Verbindungselementes weist entsprechende Hinterschneidungen auf. The groove of the other connecting element has corresponding undercuts. Beim Ineinanderstecken der Verbindungselemente werden die beiden Lippen der Feder zusammengedrückt und federn wieder auseinander, wenn die Vorsprünge in die Hinterschneidungen eingreifen. During nesting of the connecting elements, the two lips of the spring are pressed together and spring apart again if the projections engage in the undercuts.

Die DE-A-72 07 395 offenbart ein Verbindungselement, mit dem zwei Paneele, die schwalbenschwanzförmige Nuten aufweisen, miteinander verbunden werden können. The DE-A-72 07 395 discloses a connecting element, with the two panels that have dovetail-shaped grooves can be connected together. Entsprechend der Schwalbenschwanzform der Nuten ist das Verbindungselement keilförmig ausgebildet und beidseitig mittig geschlitzt. According to the dovetail shape of the grooves the connecting element is wedge-shaped and centrally slotted on both sides. Durch den Schlitz kann das Verbindungselement zusammengepresst werden, so dass die zum Schwalbenschwanz der Nuten komplementäre Form aufgehoben wird und das Federstück seitlich in die Nut eingeschoben werden kann. Through the slot, the connecting element can be pressed together, so that the complementary to the dovetail grooves of the mold is released and the spring piece can be inserted into the groove laterally. Dort federn die Schenkel zurück und füllen die Nuten im Querschnitt aus. There, the legs spring back and fill the grooves of in cross section. Ähnliche Verbindungselemente offenbart die US-A-727, 862. Darüber hinaus offenbart diese Druckschrift auch Holzpaneele zur Ausbildung von Säulen, die auf einer Seite eine Nut und auf der gegenüberliegenden Seite eine Feder aufweisen. Similar connecting elements is disclosed in US-A-727, 862. Moreover, this document discloses also wooden panels to form columns, which have on one side a tongue and on the opposite side a spring. Der Nutgrund ist gerundet und weist einen Keil auf. The bottom of the groove is rounded and has a wedge. Die Feder ist mittig geschlitzt, wobei der Schlitz sich zum Kern hin verjüngt. The spring is centrally slit, said slot is tapered toward the core. Werden die Paneele ineinander gesteckt, greift der Keil in den Schlitz der Feder ein und spreizt diese auf, so dass sich die aufgeweitete Feder gegen die Innenfläche der Nut anlegt. If the panels fitted into one another, the wedge engages in the slot of the spring and spreads to this, so that the expanded spring to bear against the inner surface of the groove. Damit die Verbindung nicht gelöst werden kann, muss in der Verbindung eine Spannung aufrecht erhalten werden. So the connection can not be solved in the connection voltage must be maintained.

Die DE-A-195 03 948 offenbart ein Bauelement, das als Trägerelement zur Verkleidung von Nassräumen dient. DE-A-195 03 948 discloses a device that serves as a support element for covering wet rooms. Auf das Trägergrundelement können keramische Fliesen oder dergleichen aufgebracht sein. To the support base member ceramic tiles or the like may be applied. Die Feder ist an ihrer Spitze mit einer Aufnahme versehen und weist an ihrer Unterseite zwei Mulden und an ihrer Oberseite eine weitere Mulde auf, die gegenüber der Federspitze zurückversetzt angeordnet sind. The spring is provided at its tip with a receptacle and has on its underside two recesses and on its upper side a further depression, which are arranged set back relative to the pen tip. Diese Mulden sollen zusammen mit Erhöhungen in der Nut eine Rückschubsicherung der ansonsten lösbaren Verbindung bilden. These troughs are intended to form, together with increases in the groove a back thrust otherwise securing the releasable connection. Eine Verriegelung zweier miteinander verbundener Trägerelemente ist nicht vorgesehen und auch nicht erwünscht. A locking two mutually connected support elements is not intended and also not desired. Vielmehr ist die Profilierung von Feder und Nut so ausgebildet, dass ein Fügespiel in der Verbindungsstelle verbleibt, um die Stoßfuge einstellen zu können. Rather, the profiling of the tongue and groove is formed so that a joining play remains in the joint, in order to adjust the butt joint.

Von dieser Problemstellung ausgehend soll das eingangs beschriebene Paneel so fortgebildet werden, dass beim Zusammenfügen zweier Paneele möglichst geringe Kräfte in der Nut wirken und nach der Verriegelung die Verbindung spannungsfrei ist, damit eine von außen nicht sichtbare Zerstörung des Materials in der Verbindungsstelle verhindert wird. Starting from this problem, the panel initially described is intended to be trained so that at the joining of two panels lowest possible forces in the groove and after locking the connection is free of stress, so that a non-visible from the outside destruction of the material in the joint is prevented.

Zur Problemlösung zeichnet sich ein gattungsgemäßes Paneel dadurch aus, dass die Feder durch einen zur Oberseite des Paneels in Längsrichtung parallel verlaufenden Schlitz in zwei elastisch zueinander bewegbare Federteile geteilt wird, und dass die Nut im Nutgrund einen ersten, keilförmigen Vorsprung aufweist, der bei zusammengesteckten Paneelen in den Schlitz eingreift To solve the problem, a generic panel is characterized in that the spring is divided by a plane parallel to the upper side of the panel longitudinally slit into two elastically to each other movable spring members, and that the groove in the groove base has a first, wedge-shaped projection which in the assembled panels engages in the slot

Durch diese Ausgestaltung wird die Feder zweiteilig und elastisch. By this configuration, the spring is in two parts and elastic. Die beiden Federteile werden beim Einfügen in die Nut eines anderen Paneels zusammengedrückt. The two spring members are compressed into the groove of another panel upon insertion. Kommen die Verrastmittel zur Überdeckung, federn die beiden Teile auseinander und die formschlüssige Verbindung wird hergestellt. The latching means coming to overlap, the two parts spring apart and the form-locking connection is made.

Die Spitze des Vorsprungs liegt auf der Höhe des Schlitzes in der Feder und greift beim Zusammenstecken zweier Paneele in den Schlitz ein und zwingt die beiden Federteile nach außen, so dass eine sichere Verrastung gegeben ist. The tip of the projection is located at the height of the slot in the spring and engages the plugging together of two panels in the slot and forces the two spring members to the outside, so that a secure locking is provided. Gleichzeitig wird die Stabilität in der Feder-Nut-Verbindung erhöht, da die beiden Teile der Feder an ihren freien Enden abgestützt werden. At the same time the stability is increased in the tongue and groove connection, as the two parts of the spring are supported at their free ends.

Die Elastizität der beiden Federteile steigt mit der Tiefe des Schlitzes, so dass dieser vorzugsweise über die volle Breite der Feder reicht. The elasticity of the two spring parts increases with the depth of the slot so that it preferably extends across the full width of the spring.

Die Verrastmittel werden vorzugsweise gebildet durch einen an der Feder vorgesehenen, in Richtung der Unterseite des Paneels ragenden Vorsprung und einer in der Nut vorgesehenen Vertiefung. The latching means are preferably formed by a projection provided on the spring, in the direction of the underside of the panel projecting projection and a recess provided in the groove. Auch kann der Vorsprung an der Nut und die Vertiefung in der Feder ausgebildet sein. Also the protrusion on the tongue and the recess may be formed in the spring.

Vorteilhaft ist es, wenn der Vorsprung und die Vertiefung zueinander so angeordnet sind, dass zwei zusammengesteckte Paneele zumindest an der Verbindungsstelle der Oberseiten unter Vorspannung stehen. it when the projection and the recess are arranged to one another such that two plugged-together panels are provided, at least at the juncture of the upper sides under pretension is advantageous. Dadurch wird eine dichte Verbindung an der die Sichtfläche bildenden Oberseite geschaffen und das Eindringen von Feuchtigkeit verhindert, ohne dass eine weitere Abdichtung notwendig ist. Thus, a tight connection is at the visible surface forming top created and the ingress of moisture prevented without a further sealing is required.

Die Feder und die Nut können sowohl an den Längs- als auch an den Querseiten des Paneels ausgebildet sein, so dass insbesondere beim Verlegen eines Fussbodens an allen Seiten dieselbe Verbindungstechnik anwendbar ist, so dass das Verlegen erleichtert wird. The tongue and the groove may be formed both on the longitudinal and on the transverse sides of the panel, so that in particular is applicable on all sides of the same link technology when laying a foot bottom, so that the installation is facilitated.

Mit Hilfe einer Zeichnung soll ein Ausführungsbeispiel der Erfindung nachfolgend näher erläutert werden. With the aid of a drawing, an embodiment of the invention will be explained in more detail below. Es zeigt: It shows:

Figur 1 - Figure 1 -
den Schnitt durch ein Paneel; the section through a panel;
Figur 2 - Figure 2 -
den Schnitt an der Verbindungsstelle zweier ineinandergesteckter Paneele. the cut at the junction of two of stacked panels.

Das Paneel 1, 2 besteht aus einem Holzwerkstoff, beispielsweise MDF und weist eine Oberseite 9, auf der eine Dekorschicht 10 aufgebracht ist, und eine Unterseite 11 auf. The panel 1, 2 is made of a wood material, such as MDF and has an upper surface 9 on which a decorative layer 10 is applied, and a bottom 11. An sich gegenüberliegenden Seiten ist jedes Paneel 1, 2 mit einer Feder 4 und einer Nut 3 versehen. On opposite sides of each panel 1, 2 is provided a groove 3 with a spring 4 and. Über die volle Länge (hier nicht sichtbar) ist die Feder 4 mittig mit einem Schlitz 5 versehen, dessen Tiefe über die volle Breite B der Feder 4 reicht. Over the full length (not visible here), the spring 4 is provided centrally with a slot 5, the depth of which extends over the full width B of the spring. 4 Der Schlitz teilt die Feder 4 in einen unteren Teil 4a und einen oberen Teil 4b, die elastisch zueinander bewegbar sind. The slot divides the spring 4 in a lower portion 4a and an upper part 4b, which are elastically movable towards one another. Die Nut 3 ist am Nutgrund mit einem nach aussen weisenden, keilförmigen Vorsprung 8 versehen. The groove 3 is provided at the groove base with an outwardly directed, wedge-shaped projection. 8 Die Spitze des Keils liegt in etwa in der Nutmitte und korrespondiert zu der Höhe des Schlitzes 5. Die Tiefe der Nut 3 ist größer als die Breite B der Feder. The tip of the wedge is located approximately in the center of the groove and corresponding to the height of the slot 5. The depth of the groove 3 is greater than the width B of the spring.

Die Unterlippe 3a der Nut 3 ist mit einer Vertiefung 7 versehen. The lower lip 3a of the groove 3 is provided with a recess. 7 Der untere Teil 4a der Feder 4 weist einen Vorsprung 6 auf, der in seiner Kontur zur Vertiefung 7 korrespondiert. The lower part 4a of the spring 4 has a projection 6, which corresponds in its contour to the recess. 7 Wie Figur 2 zeigt, greift bei zwei ineinandergesteckten Paneelen 1, 2 der Vorsprung 8 der Nut 3 in den Schlitz 5 der Feder 4 ein und drückt die beiden Federteile 4a, 4b auseinander, wobei der Vorsprung 6 in die Vertiefung 7 gezwungen wird. As Figure 2 shows, engages with two nested panels 1, 2 of the projection 8 of the groove 3 in the slot 5 of the spring 4, and pushes the two spring members 4a, 4b apart, the projection 6 is forced into the recess. 7 Dadurch verrasten die Paneele 1, 2 ineinander und ein Verschieben entgegen der Verbindungsrichtung 12 ist wirksam ausgeschlossen. Thus, the panels 1, 2 engage each other and a displacement against the direction of connection 12 is effectively excluded.

Die Anordnung des Vorsprungs 6 und der Vertiefung 7 zueinander ist so gewählt, dass die Paneele 1, 2 zumindest an der Verbindungsstelle 14 der Oberseite 9 unter Vorspannung stehen, so dass eine dichte Verbindung hergestellt wird. The arrangement of the projection 6 and the recess 7 from one another is chosen such that the panels 1, 2 are biased at least at the junction 14 of the top 9, so that a tight connection is made. Um die Spannung nicht zu groß werden zu lassen, was beim Verlegen (Ineinanderstecken) der Paneele 1, 2 zu einem erhöhten Kraftaufwand führen würde, ist die Oberlippe 3b der Nut 3 an der Stirnseite leicht abgeschrägt und das Paneel 1, 2 an der gegenüberliegenden Seite ausgenommen, so dass sich zwischen den verbundenen Paneelen 1, 2 ein Freiraum 13 ausbildet. In order not to become too large, the voltage, which during the laying (nesting) of the panels 1, 2 would lead to an increased effort, the upper lip 3b of the groove 3 slightly bevelled on the front side and the panel 1, 2 on the opposite side except, so that between the connected panels 1, 2, a free space 13 is formed.
