Description

Mechanische Verbindung von Paneelen Mechanical connection of panels
Die Erfindung betrifft eine mechanische Verbindung von flächigen Paneelen, wie sie in typischer Weise für einen Bodenbelag, beispielsweise Parkett oder Laminatfußboden, oder für Decken- und Wandverkleidungen verwendet werden.The invention relates to a mechanical connection of flat panels, as are typically used for a floor covering, for example parquet or laminate flooring, or for ceiling and wall coverings.
In allen Fällen lassen sich die einzelnen Paneelen durch eine mechanische Verbindung, d. h. Verriegelung, zu einer flächigen Gesamtheit vereinen, so daß ein Verlegen der Paneelen ohne Klebstoffe oder zusätzliche mechanische Befestigungselemente, z. B. Schrauben oder Nägel, möglich ist. Insbesondere ergibt sich daraus der Vorteil, daß die Paneelen sich ohne ein Verleimen verlegen und somit wieder entfernen lassen können.In all cases, the individual panels can be mechanically connected, i.e. H. Lock, unite to a flat whole, so that a laying of the panels without adhesives or additional mechanical fasteners such. B. screws or nails, is possible. In particular, this results in the advantage that the panels can be laid without gluing and can thus be removed again.
Aus der JP 3-169967 A, von der die vorliegende Erfindung ausgeht, ist eine mechanische Verbindung von Fußbodenpaneelen bekannt. Die Paneelen weisen entlang einer Seitenkante eine darin ausgebildete Nut auf, die von einer oberen Lippe und einer unteren Lippe gebildet wird und sich parallel zur Seitenkante erstreckt. An der gegenüberliegenden Seitenkante der gleichen Paneele ist eine Feder ausgebildet, die sich parallel zu dieser Seitenkante erstreckt. In der Nut ist eine Vertiefung ausgebildet, die eine schräg zur Oberseite der Paneele verlaufende Verriegelungsoberfläche aufweist. An der Feder ist ein dazu korrespondierendes Verriegelungselement ausgebildet, die eine schräg zur Oberseite verlaufende Verriegelungsoberfläche aufweist. Des weiteren sind in der Nut und an der Feder im Bereich der jeweiligen Seitenkante parallel zur Oberseite verlaufende Paßflächen ausgebildet, die als Widerlager für die Verriegelungsoberflächen der Vertiefung der Nut und des Verriegelungselements der Feder dienen. Die Paßfläche der Nut überdeckt dabei in Richtung parallel zur Oberseite die Verriegelungsfläche, die gegenüberliegend in der Nut ausgebildet ist. Gleiches gilt für die Paßfläche und die Verriegelungsfläche der Feder, da die Profile der Nut und der Feder zumindest in diesen Abschnitten korrespondierend ausgebildet sind. Die Paßflächen und die Verriegelungsoberflächen liegen im verriegelten Zustand der Verbindung Paarweise aneinander an, um die" oberen Flächen der Seitenkanten 3 und 4 in Anlage aneinander zu halten. Somit wird durch das Zusammenwirken der Paßflächen und der Verriegelungsflächen erreicht, daß die aneinander anstoßenden Seitenkanten zweier Paneelen eng aneinander anliegen und eine nahezu spaltfreie Verbindung bilden.A mechanical connection of floor panels is known from JP 3-169967 A, from which the present invention is based. The panels have a groove formed therein along a side edge, which is formed by an upper lip and a lower lip and extends parallel to the side edge. A spring is formed on the opposite side edge of the same panels and extends parallel to this side edge. A recess is formed in the groove, which has a locking surface that extends obliquely to the top of the panels. A corresponding locking element is formed on the spring, which has a locking surface that runs obliquely to the upper side. Furthermore, in the groove and on the tongue in the area of the respective side edge parallel to Top fitting surfaces formed, which serve as an abutment for the locking surfaces of the recess of the groove and the locking element of the spring. The mating surface of the groove covers the locking surface in the direction parallel to the top, which is formed opposite in the groove. The same applies to the mating surface and the locking surface of the tongue, since the profiles of the groove and the tongue are correspondingly formed at least in these sections. The mating surfaces and the locking surfaces abut one another in pairs in the locked state of the connection in order to hold the "upper surfaces of the side edges 3 and 4 in contact with one another. Thus, by the interaction of the mating surfaces and the locking surfaces, it is achieved that the abutting side edges of two panels lie close together and form an almost gap-free connection.
Weitere mechanische Verbindungen von Paneelen sind aus dem Stand der Technik der WO 94/26999, WO 96/27721, WO 97/47834 und WO 98/58142 bekannt.Further mechanical connections of panels are known from the prior art of WO 94/26999, WO 96/27721, WO 97/47834 and WO 98/58142.
Den aus dem Stand der Technik bekannten mechanischen Verbindungen von Paneelen ist auf der einen Seite gemeinsam, daß sie zwar in Richtung parallel zur Oberseite der Paneelen gerichtet eine zuverlässige mechanische Verriegelung ermöglichen, daß sie jedoch nur eine geringe Stei- figkeit gegenüber einem Verdrehen der Paneele um die aneinander angrenzenden Seitenkanten aufweisen. Somit können relativ einfach die Paneele gegeneinander verschwenkt werden, so daß es zu einem Lösen der mechanischen Verbindung kommt. Dieses ist teilweise sogar im Stand der Technik für ein einfaches Verlegen der Paneelen gewünscht. Zum anderen weisen aus diesem Stand der Technik bekannte Paneelen zwar eine ausreichende Steifigkeit gegenüber dem zuvor erwähnten Verkanten und Verschwenken der Paneelen zueinander auf, jedoch besitzen diese Verbindungen keine ausreichende Festigkeit der Verriegelung der Paneele miteinander auf.On the one hand, the mechanical connections of panels known from the prior art have in common that, although they are directed in the direction parallel to the top of the panels, they enable reliable mechanical locking, but that they have only a slight rigidity against twisting of the panels which have adjacent side edges. The panels can thus be pivoted relative to one another relatively easily, so that the mechanical connection is released. This is sometimes even desirable in the prior art for easy installation of the panels. On the other hand, known from this prior art Although panels have sufficient rigidity with respect to the aforementioned tilting and pivoting of the panels relative to one another, these connections do not have sufficient strength for the interlocking of the panels with one another.
Der Erfindung liegt daher das technische Problem zugrunde, eine mechanische Verbindung von Paneelen mit verbesserten Verriegelungs- und Stabilitätseigenschaften anzugeben.The invention is therefore based on the technical problem of specifying a mechanical connection of panels with improved locking and stability properties.
Das" zuvor aufgezeigte technische Problem wird erfindungsgemäß durch eine Verbindung mit den Merkmalen des Oberbegriffes des Anspruches 1 dadurch gelöst, daß die Nut im Bereich des Nutgrundes parallel zur Oberseite verlaufende Paßflächen aufweist und daß die Feder im Bereich der Endflächen parallel zur Oberseite verlaufende Paßflächen aufweist, wobei die Paßflächen im verriegelten Zustand der Verbindung aneinander anliegen.The " previously indicated technical problem is solved according to the invention by a connection with the features of the preamble of claim 1 in that the groove in the area of the bottom of the groove has parallel fitting surfaces and that the tongue in the end surfaces has parallel fitting surfaces, the mating surfaces abutting one another in the locked state of the connection.
Erfindungsgemäß ist somit erkannt worden, daß zusätzlich zur Verriegelung der Feder innerhalb der Nut Paßflächen angeordnet werden, die eine Stabilisierung der Verbindung gegenüber einem Verkanten der Paneelen zueinander bewirken. Die Verriegelung wird somit durch das Paar von Verriegelungsoberflächen und dem als Widerlager dazu dienenden Paar von Paßflächen, die im Bereich der Seitenkanten angeordnet sind verwirklicht, realisiert. Ein Auseinanderbewegen der beiden Paneele in einer Ebene parallel zu den Oberseiten und senkrecht zu den Seitenkanten wird also durch die von den Verriegelungsoberflächen erzeugten Kraft wirkungsvoll verhindert. Die Stabilisierung der beiden Paneele im verriegelten Zustand gegenüber einem Verkanten oder Verschwenken entlang der Seitenkanten wird durch die zusätzlichen Paßflächen im Bereich des Nutgrundes bzw. der Endfläche der Feder erreicht. Somit werden die Verriegelung einerseits und die Stabilisierung der Ausrichtung der beiden Paneelen von unterschiedlichen Paßflächenpaaren gebildet.According to the invention, it has thus been recognized that, in addition to locking the tongue, fitting surfaces are arranged within the groove, which stabilize the connection against tilting of the panels relative to one another. The locking is thus realized by the pair of locking surfaces and the pair of mating surfaces serving as an abutment, which are arranged in the region of the side edges. Movement of the two panels apart in a plane parallel to the upper sides and perpendicular to the side edges is thus effectively prevented by the force generated by the locking surfaces. The stabilization of the two panels in the locked state against tilting or pivoting along the side edges is achieved by the additional mating surfaces in the area of the groove base or the end surface of the tongue. Thus, the locking on the one hand and the stabilization of the alignment of the two panels are formed by different pairs of mating surfaces.
Ein weiterer Vorteil der erfindungsgemäßen mechanischen Verbindung von Paneelen liegt darin, daß die beiden Funktionsgruppen der Verriegelung und Ausrichtungsstabilisierung entlang einer Feder bzw. einer Nut ausgebildet sind, so daß ein gerade im Bereich von Laminatfußböden gewünschte geringe Dicke der Paneele eingehalten werden kann.Another advantage of the mechanical connection of panels according to the invention is that the two functional groups of locking and alignment stabilization are formed along a tongue or a groove, so that a small thickness of the panels desired in the area of laminate floors can be maintained.
In einer bevorzugten Ausgestaltung ist der Abstand zwischen der Verriegelungsfläche und der Paßfläche im Bereich der Seitenkanten größer als der Abstand zwischen der Paßflächen im Bereich des Nutgrundes bzw. der Endfläche der Feder. Dadurch wird erreicht, daß das zu Beginn des Hersteilens der mechanischen Verbindung als erstes in die Nut eintretende Ende der Feder leicht von der Nut aufgenommen werden kann, da, sofern beide Paneelen auf dem gleichen Untergrund angeordnet sind, die Feder ohne mechanischen Widerstand ein vorgegebenes Stück in die Nut eindringen kann, so daß während des Zusammenfügens der Paneelen keine Schwierigkeiten auftreten, die im Stand der Technik beispielsweise durch ein Ansetzen und Verschwenken der Paneelen zueinander hervorgerufen werden. Zudem verjüngt sich die Nut von ihrer Öffnung hin bis. zum Nutgrund bzw. die Feder von dem der Paneele zugewandten Ende zur Endfläche hin, wodurch die Stabilität der Profile der Seitenkanten beider Paneelen verbessert wird. Dazu kann eine weitere Oberfläche in der Nut ausgebildet sein, die schräg zur Oberseite verläuft und die der Vertiefung gegenüberliegend angeordneten Paßflächen miteinander verbindet. Ebenso kann auf der anderen Seite der Nut eine schräg zur Oberseite verlaufende Oberfläche ausgebildet sein, die die Verriegelungsfläche mit der im Bereich des Nutgrundes angeordnete Paßfläche verbindet.In a preferred embodiment, the distance between the locking surface and the mating surface in the region of the side edges is greater than the distance between the mating surfaces in the region of the groove base or the end surface of the tongue. It is thereby achieved that the end of the tongue entering the groove at the beginning of the establishment of the mechanical connection can easily be picked up by the groove, since, provided that both panels are arranged on the same surface, the tongue is a predetermined piece without mechanical resistance can penetrate into the groove, so that no difficulties occur during the joining of the panels, which are caused in the prior art, for example, by attaching and pivoting the panels to one another. In addition, the groove tapers from its opening to. to the bottom of the groove or the tongue from the end facing the panels to the end face, which improves the stability of the profiles of the side edges of both panels. For this purpose, a further surface can be formed in the groove, which runs obliquely to the upper side and connects the mating surfaces arranged opposite the recess. Likewise, on the other side of the groove, a surface running obliquely to the upper side can be formed, which connects the locking surface with the mating surface arranged in the region of the groove base.
Des weiteren ist es bevorzugt, daß die Endfläche der oberen Lippe und die Endfläche der unter Lippe, die gemeinsam die Nut bilden, im wesentlichen einer Ebene angeordnet" sind. Mit anderen Worten erstrecken sich die beiden Lippen im wesentlichen gleich weit entlang der Seitenkante, so daß bei einem Herstellen der mechanischen Verbindung der Paneelen die zum Verrasten erforderliche Kraft mittels eines Schlagklotzes ausgeübt werden, wobei der Schlagklotz sowohl an der oberen als auch an der unteren ~ Lippe anliegt und eine möglichst große Angriffsfläche erhält. Dadurch werden wirkungsvoll Beschädigungen der Seitenkanten vermieden.Furthermore, it is preferred that the end face of the upper lip and the end surface are the "positioned below lip that together form the groove is substantially a plane. In other words, the two lips extend essentially the same distance along the side edge, so that in a production of the mechanical connection of the panels required for latching force can be applied by means of a tapping block, with the tapping block is present both on the upper and on the lower ~ lip and obtains the largest possible contact surface. This damage can be effectively avoided the side edges.
Darüber hinaus ist es bevorzugt, daß die obere Lippe und die untere Lippe einstückig mit der Paneele ausgebildet sind. Dieses ist herstellungstechnisch durch ein Herausfräsen des Profils der Nut bzw. des Profils der Feder aus der Seitenkante der Paneele möglich, woraus sich herstellungstechnisch Vorteile ergeben. Daneben ist es selbstverständlich auch möglich, die Feder, die obere und/oder untere Lippe separat herzustellen und diese mit den Paneelen zu verbinden, um die gleichen Verriegelungs- und Ausrichtungsstabilisierungseigenschaften zu erlangen.In addition, it is preferred that the upper lip and the lower lip are integrally formed with the panels. This is possible in terms of production technology by milling out the profile of the groove or the profile of the tongue from the side edge of the panels, which results in advantages in terms of production technology. In addition, it is of course also possible to manufacture the spring, the upper and / or lower lip separately and to connect them to the panels in order to achieve the same locking and alignment stabilizing properties.

Sämtliche der nachfolgend beschriebenen Oberflächen erstrecken sich ganz oder zumindest abschnittsweise entlang einer Längs- oder Querkante der Paneelen 1 und 2, die im folgenden allgemein als Seitenkanten bezeichnet werden.All of the surfaces described below extend entirely or at least in sections along a longitudinal or transverse edge of the panels 1 and 2, which are generally referred to below as side edges.
Fig. 1 zeigt eine Paneele 1, in deren äußere Kante 3 eine Nut 34 eingearbeitet ist. Dazu weist die Kante 3 eine Vielzahl von unterschiedlich zur Oberfläche 5 geneigte Oberflächen auf, die im folgenden beschrieben werden.Fig. 1 shows a panel 1, in the outer edge 3, a groove 34 is incorporated. For this purpose, the edge 3 has a multiplicity of surfaces which are inclined differently from the surface 5 and which are described below.
Eine Oberfläche 11 ist im oberen Bereich der Kante 3 benachbart zur Oberseite 5 angeordnet. Eine Oberfläche 11a verläuft unter einem flachem Winkel zur Oberfläche 11 geneigt in Richtung des Nutgrundes 7. Eine Oberfläche 12 verläuft im wesentlichen parallel zur Oberseite 5 in Richtung des Nutgrundes 7 von der Oberfläche 11a aus betrachtet. An die Oberfläche 12 schließen sich Oberflächen 13 und 14 an, wobei die Oberfläche 13 unter einem flachen Winkel nach unten weisend die Oberflächen 12 und 14 mit- einander verbindet. Dabei ist die Oberfläche 14 parallel zur Oberseite 5 der Paneel 1 ausgerichtet und endet am Nutgrund 7. Somit bilden die Oberflächen 12, 13 und 14 den oberen Rand der Nut 34 in der Paneele 1.A surface 11 is arranged in the upper region of the edge 3 adjacent to the upper side 5. A surface 11a is inclined at a flat angle to the surface 11 in the direction of the groove base 7. A surface 12 extends essentially parallel to the upper side 5 in the direction of the groove base 7 when viewed from the surface 11a. Surfaces 13 and 14 adjoin surface 12, surface 13 facing surfaces 12 and 14 at a flat angle downwards. connects each other. The surface 14 is aligned parallel to the top 5 of the panel 1 and ends at the groove base 7. Thus, the surfaces 12, 13 and 14 form the upper edge of the groove 34 in the panel 1.
Die untere Oberfläche der Nut 34 wird durch Oberflächen 15, 16, 17 und 18 gebildet, die wie folgt ausgerichtet sind. Die Oberfläche 15 verläuft parallel zur Oberfläche 14, sie ist somit auch im wesentlichen parallel zur Unterseite 6 ausgerichtet. Die Oberfläche 16 schließt sich an die Oberfläche 15 an und verläuft schräg nach unten unter einem flachen Winkel zur Oberfläche 15. Die sich anschließende Oberfläche 17 ist entgegengesetzt nach oben ausgerichtet, wobei der Anstiegswinkel der Oberfläche 17 betragsmäßig größer als der Winkel der Oberfläche 16 ist, den dieser mit der horizontal verlaufenden Oberfläche 15 bildet. An die Oberfläche 17 schließt sich die Oberfläche 18 an, die parallel zur Oberfläche 12 und somit zur Oberseite 5 bzw. Unterseite 6 der Paneele 1 ausgerichtet ist.The lower surface of the groove 34 is formed by surfaces 15, 16, 17 and 18 which are oriented as follows. The surface 15 runs parallel to the surface 14, it is thus also aligned essentially parallel to the underside 6. The surface 16 adjoins the surface 15 and runs obliquely downward at a flat angle to the surface 15. The adjoining surface 17 is oriented in the opposite upward direction, the angle of rise of the surface 17 being greater in magnitude than the angle of the surface 16, which it forms with the horizontally extending surface 15. The surface 17 adjoins the surface 18, which is aligned parallel to the surface 12 and thus to the top 5 or bottom 6 of the panels 1.
Die Oberfläche 19 bildet die untere Endfläche der Kante 3 und ist im wesentlichen parallel zur Oberfläche 11 ausgerichtet. Vorzugsweise liegen die Oberflächen 11 und 19 dabei in einer Ebene. Die Oberfläche 19a bildet den Übergang zwischen den Oberflächen 18 und 19 und ist schräg nach innen gerichtet geneigt angeordnet.The surface 19 forms the lower end surface of the edge 3 and is aligned essentially parallel to the surface 11. The surfaces 11 and 19 preferably lie in one plane. The surface 19a forms the transition between the surfaces 18 and 19 and is arranged inclined obliquely inwards.
Die Nut 34 der Paneele 1 wird somit durch eine obere Lippe 30 und. eine untere Lippe 31 gebildet. Dabei wird die obere Lippe 30 durch die Oberflächen 5, 11, 11a, 12, 13 und 14 umrandet, wobei die Oberfläche 11 die Endfläche der oberen Lippe 30 bildet. Die untere Lippe 31 wird von den Oberflächen 6, 15, 16, 17, 18, 19 und 19a umgrenzt, wobei die Oberfläche 19 die Endfläche der unteren Lippe 31 bildet.The groove 34 of the panels 1 is thus through an upper lip 30 and. a lower lip 31 is formed. The upper lip 30 is surrounded by the surfaces 5, 11, 11a, 12, 13 and 14, the surface 11 forming the end face of the upper lip 30. The lower lip 31 is delimited by the surfaces 6, 15, 16, 17, 18, 19 and 19a, surface 19 forming the end surface of lower lip 31.
Fig. 2 zeigt eine Paneele 2, die an einer Kante 4 eine Feder 32 aufweist, die vorzugsweise integral mit der Paneele 2 ausgebildet ist. Die Kante 4 weist eine obere Fläche 21 auf, die sich an die Oberseite 9 der Paneele 2 anschließt.. Dabei verläuft die Oberfläche 21 im wesentlichen vertikal nach unten. Die Feder 32 wird von Oberflächen 22, 23, 24, 8, 25, 26, 27 und 28 umschlossen. Die Oberfläche 22 verläuft im wesentlichen horizontal und somit" parallel zur Oberfläche 9 der Paneele 2. Die Oberfläche 23 ist unter einem flachen Winkel nach unten geneigt ausgerichtet und verbindet die beiden Oberflächen 22 und 24 miteinander. Die Oberfläche 24 ist wiederum parallel zur Oberseite 9 der Paneele 2 ausgerichtet und erstreckt sich somit im wesentlichen horizontal. Die Oberfläche 24 endet an der Endfläche 8 der Feder 32.FIG. 2 shows a panel 2 which has a spring 32 on an edge 4, which is preferably formed integrally with the panel 2. The edge 4 has an upper surface 21 which adjoins the upper side 9 of the panels 2. , The surface 21 extends essentially vertically downwards. The spring 32 is enclosed by surfaces 22, 23, 24, 8, 25, 26, 27 and 28. The surface 22 runs essentially horizontally and thus "parallel to the surface 9 of the panels 2. The surface 23 is oriented inclined downwards at a flat angle and connects the two surfaces 22 and 24 to one another. The surface 24 is in turn parallel to the upper side 9 of the panel Panels 2 are aligned and thus extend substantially horizontally, and surface 24 ends at end surface 8 of spring 32.
Die unteren Oberflächen der Feder 32 haben folgende Ausrichtungen. Die Oberfläche 25 grenzt an die Endfläche 8 an und verläuft parallel zur Oberfläche 24 bzw. im wesentlichen parallel zur Unterseite 10 der Paneele 2. Die Oberfläche 26 verläuft von der Endfläche 8 der Feder 32 wegweisend nach unten, während die Oberfläche 27 wieder schräg nach oben verlaufend ausgerichtet ist. Dabei ist der Steigungswinkel der Oberfläche 27 größer als der Winkel der Oberfläche 26, den diese mit der horizontalen einschließt. Die Oberfläche 28 schließt sich an die Oberfläche 27 an und geht in die Oberfläche 29 der Kante 4 über. Die Oberfläche 29 verläuft dabei im wesentlichen vertikal, also senkrecht zur Unterseite 10 der Paneele 2. Die Oberflächen 21 und 29 sind somit im wesentlichen parallel zueinander ausgerichtet, liegen jedoch nicht in ei- ner Ebene, sondern die Oberfläche 29 ist geringfügig in Richtung des Körpers der Paneele 2 gegenüber der Oberfläche 21 zurück versetzt.The lower surfaces of the spring 32 have the following orientations. The surface 25 adjoins the end surface 8 and runs parallel to the surface 24 or essentially parallel to the underside 10 of the panels 2. The surface 26 runs downward from the end surface 8 of the spring 32, while the surface 27 again slopes upwards is aligned. The angle of inclination of the surface 27 is greater than the angle of the surface 26 which it includes with the horizontal. The surface 28 adjoins the surface 27 and merges into the surface 29 of the edge 4. The surface 29 extends essentially vertically, that is to say perpendicularly to the underside 10 of the panels 2. The surfaces 21 and 29 are thus aligned essentially parallel to one another, but do not lie in a ner level, but the surface 29 is slightly offset in the direction of the body of the panels 2 relative to the surface 21.
Fig. 3 zeigt die beiden Paneele 1 und 2, die mechanisch miteinander verbunden sind. Dazu steht die Feder 32 der Paneele 2 mit der oberen Lippe 30 und der unteren Lippe 31 der Nut 34 der Paneele 1 in Eingriff.Fig. 3 shows the two panels 1 and 2, which are mechanically connected to each other. For this purpose, the tongue 32 of the panels 2 is in engagement with the upper lip 30 and the lower lip 31 of the groove 34 of the panels 1.
Im verrasteten, bzw. verriegelten Zustand liegen die zuvor beschriebenen Oberflächen der Nut 34 einerseits und der -Feder andererseits zumindest teilweise paarweise flächig aneinander an. Daraus ergeben sich zumindest die mit den offenen Dreiecken und den Großbuchstaben A, B, C und D gekennzeichneten Paare von Paßflächen 12,22; 14,24; 15,25 und 17, 27.In the locked or locked state, the previously described surfaces of the groove 34, on the one hand, and the tongue, on the other hand, lie flat against one another at least partially in pairs. This results in at least the pairs of fitting surfaces 12, 22 marked with the open triangles and the capital letters A, B, C and D; 14.24; 15, 25 and 17, 27.
Die beiden oberen Paßflächenpaare 12, 22 und 14, 24 wirken einem Höhenversatz der beiden gekuppelten Teile, also Feder 32 einerseits und Nut 34 aus Lippen 30 und 31 andererseits entgegen. Dadurch wird verhindert, daß die Paneele 2 gegenüber der Paneele 1 verkanten kann, insbesondere während des Zusammenfügens .The two upper pairs of fitting surfaces 12, 22 and 14, 24 counteract a height offset of the two coupled parts, that is to say spring 32 on the one hand and groove 34 made of lips 30 and 31 on the other hand. This prevents the panels 2 from tilting relative to the panels 1, especially during assembly.
Beide Paare von Oberflächen 12, 22 und 14, 24 weisen gegenüberliegend angeordnete Paare von Oberflächen 15,25 und 17,27 als Widerlager auf. Durch diesen Paßsitz wird die Feder 32 sowohl am vorderen, der Endfläche 8 zugewandten Ende, als auch am hinteren, der Kante 4 zugewandten Ende in ihrer Position festgelegt. Dabei sind die Oberflächenpaare 14,24 und 15, 25 beabstandet zu den Oberflächenpaaren 12,22 und 17,27 angeordnet, wobei der Abstand möglichst groß gewählt ist. Dadurch wird eine hohe Stabilität und insbesondere Biegesteifigkeit gegenüber einer durch eine senkrecht auf die Oberflächen 5 und 9 der gekoppelten Paneelen 1 und 2 wirkenden Belastung erreicht.Both pairs of surfaces 12, 22 and 14, 24 have oppositely arranged pairs of surfaces 15, 25 and 17.27 as abutments. By this fit, the spring 32 is fixed in position both at the front end facing the end face 8 and at the rear end facing the edge 4. The surface pairs 14, 24 and 15, 25 are spaced apart from the surface pairs 12, 22 and 17.27, the distance being chosen to be as large as possible. This provides a high level of stability and, in particular, bending rigidity reached by a load acting perpendicular to the surfaces 5 and 9 of the coupled panels 1 and 2.
Darüber hinaus können die zuvor beschriebenen Wirkungen auch dadurch verstärkt und verbessert werden, daß auch die Oberflächenpaare 13,23 und 16,26 paßgenau aneinander anliegen und somit die Biegesteifigkeit verbessern.In addition, the effects described above can also be strengthened and improved by the fact that the surface pairs 13, 23 and 16, 26 also abut one another with a precise fit and thus improve the bending stiffness.
Bisher wurde das Zusammenwirken der Oberflächen in Bezug auf die Biegesteifigkeit beschrieben. Die Oberflächen 17 und- 27 bewirken, daß die Feder 32 in der von den Lippen 30 und 31 gebildeten Nut 34 festgehalten wird. Denn durch die Oberflächen 26 und 27 wird ein nach unten vorstehendes Verriegelungselement 33 der Feder 32 gebildet, die in die von den Oberflächen 16 und 17 in der Nut 34 an der unteren Lippe 31 ausgebildete Vertiefung 35 eingreift. Wie mit dem Dreieck B gekennzeichnet ist, sind die Oberflächen 17 und 27 so geneigt, daß ein Herausrutschen der Feder 32 aus der Nut 34 wirkungsvoll verhindert wird.The interaction of the surfaces with respect to the bending stiffness has been described so far. The surfaces 17 and 27 cause the spring 32 to be held in the groove 34 formed by the lips 30 and 31. Because the surfaces 26 and 27 form a downwardly projecting locking element 33 of the spring 32, which engages in the recess 35 formed by the surfaces 16 and 17 in the groove 34 on the lower lip 31. As indicated by the triangle B, the surfaces 17 and 27 are inclined so that the tongue 32 does not slip out of the groove 34 effectively.
Darüber hinaus sind die Nut 34 und die Feder 32 so genau aufeinander ausgerichtet, daß bei paßgenauem Sitz der Feder 32 in der Nut 34 die Oberflächen 11 und 21 der Kanten 3 und 4 der Paneelen 1 und 2 eng aneinander anliegen. Somit liegen die Oberflächen 9 und 5 ohne Spalt aneinander an und bilden eine durchgängige Oberfläche.In addition, the groove 34 and the tongue 32 are aligned with one another so precisely that when the tongue 32 is seated precisely in the groove 34, the surfaces 11 and 21 of the edges 3 and 4 of the panels 1 and 2 lie closely against one another. Thus, the surfaces 9 and 5 lie against one another without a gap and form a continuous surface.
Für ein Zusammenfügen werden beide Paneele 1 und 2 horizontal, also im wesentlichen parallel zu den Unterseiten 6 und 10 aufeinander zu bewegt worden. Durch einen entsprechend ausgeübten mechanischen Druck drückt die Feder 32 die untere Lippe 31 nach unten, bis die Feder 32 soweit in die Nut 34 eingeschoben worden ist, bis die unte- re Lippe 31 mit der Feder 32 verrastet. Den verrasteten Zustand zeigt Fig. 3. Dabei ist hervorzuheben, daß nur die vertikal zu den Oberseiten 5 und 9 verlaufenden Oberflächen 11 und 21 aneinander anliegen und somit die relative Position der beiden Paneele 1 und 2 definieren. Die weiteren vertikalen Oberflächenpaare 7 und 8 sowie 19 und 29 haben dagegen keine direkten mechanischen Kontakt miteinander.For assembly, both panels 1 and 2 are moved towards one another horizontally, that is to say essentially parallel to the undersides 6 and 10. By means of a correspondingly exerted mechanical pressure, the spring 32 presses the lower lip 31 down until the spring 32 has been pushed into the groove 34 until the lower right lip 31 locked with the spring 32. The latched state is shown in FIG. 3. It should be emphasized that only the surfaces 11 and 21 which run vertically to the tops 5 and 9 abut one another and thus define the relative position of the two panels 1 and 2. The other vertical surface pairs 7 and 8 and 19 and 29, however, have no direct mechanical contact with each other.
Fig. 3 zeigt weiterhin, daß die beiden Profile im verriegelten Zustand im Bereich der Oberflächen 11 und 21 sowie 7 und 8 Hohlräume bilden. Dieses dient einer Aufnahme von ggf. vorhandenen Verunreinigungen, damit die Passung zwischen den Paßflächen nicht beeinträchtigt wird. Die Hohlräume können auch Leim aufnehmen, sofern dieses für eine Fixierung der eingenommenen Position erwünscht ist. Es wird jedoch hervorgehoben, daß für das mechanische Verriegeln kein Leim erforderlich ist.Fig. 3 also shows that the two profiles in the locked state in the area of the surfaces 11 and 21 and 7 and 8 form cavities. This serves to absorb any contamination that may be present so that the fit between the mating surfaces is not impaired. The cavities can also receive glue if this is desired for fixing the position assumed. However, it is emphasized that no glue is required for mechanical locking.
Sowohl die Paneele 1 als auch die Paneele 2 können umsei- tig entweder mit dem in Fig. 1 dargestellten Profil oder mit dem in Fig. 2 dargestellten Profil versehen sein, so daß eine Mehrzahl von Paneelen 1 und 2 zu einer flächigen Anordnung miteinander verbunden werden können. Dazu weisen die Paneelen jeweils eine Längs- und eine Querseite ein Profil gemäß Fig. 1 und an den anderen Seiten gemäß Fig. 2 auf.Both the panels 1 and the panels 2 can be provided on either side with either the profile shown in FIG. 1 or with the profile shown in FIG. 2, so that a plurality of panels 1 and 2 are connected to one another in a planar arrangement can. For this purpose, the panels each have a longitudinal and a transverse side a profile according to FIG. 1 and on the other sides according to FIG. 2.
Das in den Fig. 1 bis 3 dargestellte Ausführungsbeispiel zeigt jeweils einstückige Ausführungen der Nut 34 in der Paneele 1 einerseits und der Feder 32 in bzw. an der Paneele 2. Selbstverständlich ist es auch möglich, die Feder 32 und/oder die untere Lippe 31 mehrstückig auszuführen, also bspw. Kunststoffprofile zu verwenden, die in Kombination mit den Holzwerkstoffen der Paneele eingesetzt werden. Die Erfindung ist daher nicht auf einer ein-stückige Ausführung beschränkt. The exemplary embodiment shown in FIGS. 1 to 3 each shows one-piece designs of the groove 34 in the panels 1 on the one hand and the tongue 32 in or on the panels 2. Of course, it is also possible for the tongue 32 and / or the lower lip 31 to run in several pieces, e.g. to use plastic profiles that are in Can be used in combination with the wood materials of the panels. The invention is therefore not limited to a one-piece design.
