Description

Die Erfindung bezieht sich auf eine
Nut-Feder-Verbindung zwischen zwei benachbarten Holzpa­neelen zur Verkleidung von Wänden, Decken oder dgl., wo­bei die Paneele jeweils eine Vorderfläche und eine Rück­fläche haben.The invention relates to a
Tongue and groove connection between two adjacent wooden panels for cladding walls, ceilings or the like, the panels each having a front surface and a rear surface.

Bekannte Nut-Feder-Verbindungen von Holzpaneelen sind üblicherweise derart, daß am Rand des einen Paneels eine Nut konstanter Weite, gemessen in Richtung der Dicke des Paneels eingearbeitet ist und daß am Rand des anderen Pa­neels eine Feder konstanter Dicke, gemessen in Richtung der Dicke des Paneels, vorragt. Die Weite der Nut und die Dicke der Feder entsprechen einander, so daß beim Ineinan­derschieben von Feder und Nut zur Verbindung der beiden Paneele eine gegenseitige Festlegung in beiden entgegen­gesetzten Richtungen senkrecht zur Rückfläche der Paneele erfolgt. Es wurde festgestellt, daß bei dieser Art von Nut-Feder-Verbindung das Einführen der Feder in die Nut zuweilen Schwierigkeiten macht und daß die enge Nut-Feder-­Passung ein freies Arbeiten der Paneele an der Verbindung, insbesondere beim Schwinden des Holzes unter Austrocknung, behindert. Außerdem gestaltet sich die Befestigung der Paneele am mit Nut versehenen Rand an einer die Paneele tragenden Unterkonstruktion relativ umständlich.Known tongue and groove connections of wood panels are usually such that a groove of constant width, measured in the direction of the thickness of the panel, is incorporated at the edge of one panel and that a tongue of constant thickness, measured in the direction of the thickness of the other panel, is incorporated Panels, protrudes. The width of the groove and the thickness of the tongue correspond to one another, so that when the tongue and groove are pushed together to connect the two panels, they are mutually fixed in both opposite directions perpendicular to the rear surface of the panels. It was found that with this type of tongue-and-groove connection, inserting the tongue into the groove sometimes makes it difficult and that the tight tongue-and-groove fit allows the panels to work freely on the connection, especially when the wood shrinks while drying out. with special needs. In addition, the attachment of the panels to the grooved edge on a substructure supporting the panels is relatively cumbersome.

Der Erfindung liegt die Aufgabe zugrunde, eine Nut-Feder-­Verbindung zwischen zwei benachbarten Holz-Verkleidungs­paneelen verfügbar zu machen, die zu einer wesentlichen Montageerleichterung der Paneele und zu einem verbesserten Relativbewegungsverhalten der angebrachten Paneele führt.The invention has for its object to make a tongue and groove connection between two adjacent wood cladding panels available, which leads to a significant ease of assembly of the panels and to an improved relative movement behavior of the attached panels.

Zur Lösung dieser Aufgabe ist die Nut-Feder-Verbindung erfindungsgemäß so gestaltet, wie im kennzeichnenden Teil des Anspruchs 1 angegeben.To achieve this object, the tongue and groove connection is designed according to the invention as in the characterizing part of claim 1 specified.

Durch den rückflächenseitig von der Nut vorspringenden Rand des einen Paneels entsteht dort ein Überstand hinter der Nut, der zur bequemen Anbringung von Befestigungsmit­teln genutzt werden kann, insbesondere beim Annageln oder Anschrauben oder Anheften an die Unterkonstruktion. Die Verjüngung der Nut und/oder der Feder im Verein mit dem Spiel zwischen der Nut und der Feder sowohl zu Beginn des Einführens der Nut in die Feder als auch im gänzlich zu­sammengeschobenen Zustand führt dazu, daß sich das Nach­barpaneel mit seiner Feder besonders einfach in die Nut eines bereits angebrachten Paneels einführen läßt, wobei das auch im zusammengeschobenen Zustand vorhandene Spiel mindestens im Bereich der Federwurzel bzw. der Nutausmün­dung Raum zur Unterbringung des Endes einer entsprechenden Kralle zur Befestigung des Paneels an der Unterkonstruk­tion oder der Köpfe anderer Befestigungsmittel bietet. Bei genügend großem Übermaß der Nut im Vergleich zu der Feder ist sogar ein Einführen unter einem anfänglichen Winkel des gerade zu montierenden Paneels relativ zu dem entsprechenden Nachbarpaneel, woran sich ein Einkippen in die Anbringungslage anschließt, möglich. Die Feder gleitet spielend leicht in die entsprechende Nut. Dies alles gilt auch für Paneele, die - wie es in der Praxis häufiger vor­kommt - durch Verziehen nicht mehr ganz eben sind. Der ge­nannte Überstand hilft als untere Führungsfläche beim Ein­führen der Feder in die Nut. Ferner sind Bewegungen der Paneele relativ zueinander, beispielsweise durch Tempera­turschwankungen,oder das Arbeiten der Paneele insbesondere durch Feuchtigkeitsänderungen, erleichert. Schließlich werden die Feder und/oder die rückflächenseitige Nutwange stabiler, da sie gerade im kritischen Übergangsbereich zu dem restlichen Paneel eine größere Dicke haben. Die Paneele bestehen aus einem Holzwerkstoff, insbesondere aus Massiv­holz, das an der Sichtfläche bzw. Vorderfläche des Paneels gebürstet sein kann. Es handelt sich in der Regel um ins­gesamt rechteckige, häufig langgestreckte, Verkleidungs­paneele. Als Federwurzel wird derjenige Bereich der Feder bezeichnet, der bei montierten Paneelen in den Bereich der Nutausmündung des Nachbarpaneels kommt. Diese Federwurzel stellt in der Regel das hintere Federende am Übergang in das restliche Paneel normaler Dicke dar, kann aber auch, beispielsweise bei einer im Vergleich zur Nuttiefe größeren Federhöhe ein Stück von dem geschilderten Übergang ent­fernt liegen. Daß die Weite der Nut im wesentlichen durch­gehend größer als die Dicke der Feder an der entsprechenden Stelle ist, läuft darauf hinaus, daß die Nut im wesent­lichen über ihre gesamte Tiefe von der Nutausmündung zum Nutgrund eine größere Weite als die Dicke der Feder an der entsprechenden Stelle hat, wodurch sich das geschilderte Spiel praktisch über die gesamte Nuttiefe bzw. Federhöhe ergibt. Die durch die rückflächenparallelen Oberflächen von Nut und Feder gebildeten Anlageflächen behalten auch bei Relativverschiebungen benachbarter Paneele ihre Lage bezüglich der Paneelrückflächen bzw. der Unterkonstuktion bei. Aufgrund der rückflächenseitigen Anlage der Paneele an der Unterkonstruktion ist die Feder einseitig zumindest im wesentlichen in Anlagekontakt mit einer Nutwand, wodurch trotz des genannten Spiel eine saubere Festlegung der Re­lativlage benachbarter Paneele senkrecht zu deren Rück­fläche erfolgt. Wenn man bei der Befestigung der Holzpaneele an der Unterkonstruktion mit Krallen arbeitet, die die rück­fächenseitige Nutwange umgreifen, ergibt sich der weitere Vorteil, daß die Krallen an der sich nach außen verjüngenden bzw. nach innen dicker werdenden Nutwange infolge elasti­scher und exakt halten. Man kann auch die Krallen vor dem Positionieren des jeweiligen Holzpaneels schon an der Nut­wange anklemmen, ohne daß sie leicht abfallen würden, und dann das Holzpaneel mit seiner Feder in die Nut des Nach­barpaneels einführen und an der Unterkonstruktion positi­onieren und mittels der Krallen befestigen.Due to the edge of the one panel projecting from the rear of the groove, there is a protrusion behind the groove that can be used for the convenient attachment of fasteners, in particular when nailing or screwing or tacking onto the substructure. The tapering of the groove and / or the tongue in combination with the play between the groove and the tongue both at the beginning of the insertion of the groove into the tongue and in the completely pushed-together state leads to the neighboring panel with its tongue being particularly easy in the Groove of an already attached panel can be inserted, whereby the play, even when pushed together, offers space at least in the area of the spring root or the groove opening for accommodating the end of a corresponding claw for fastening the panel to the substructure or the heads of other fastening means. If the groove is sufficiently large compared to the tongue, it is even possible to insert it at an initial angle of the panel to be assembled relative to the corresponding neighboring panel, which is followed by tipping into the mounting position. The tongue slides easily into the corresponding groove. All of this also applies to panels that - as is more common in practice - are no longer completely level due to warping. The above projection helps as a lower guide surface when inserting the tongue into the groove. Furthermore, movements of the panels relative to one another, for example due to temperature fluctuations, or the working of the panels, in particular due to changes in moisture, are facilitated. Finally, the tongue and / or the groove cheek on the rear side become more stable, since they close in the critical transition area the rest of the panel is thicker. The panels consist of a wood material, in particular solid wood, which can be brushed on the visible or front surface of the panel. They are generally rectangular, often elongated, cladding panels. The area of the tongue that comes into the area of the groove opening of the neighboring panel when the panels are installed is referred to as the tongue root. This spring root usually represents the rear end of the spring at the transition to the rest of the panel of normal thickness, but it can also be a bit away from the transition described, for example if the spring height is greater than the groove depth. The fact that the width of the groove is essentially continuously greater than the thickness of the tongue at the corresponding point means that the groove has a greater width over its entire depth from the mouth of the groove to the groove base than the thickness of the tongue at the corresponding point has, which results in the game described practically over the entire groove depth or spring height. The contact surfaces formed by the tongue and groove surfaces parallel to the rear surface retain their position with respect to the rear panel surfaces or the substructure even in the event of relative displacements of adjacent panels. Due to the rear surface-side contact of the panels on the substructure, the tongue is at least essentially in contact with a groove wall on one side, so that despite the play mentioned, the relative position of adjacent panels is defined correctly perpendicular to their rear surface. If, when fastening the wooden panels to the substructure, you work with claws that encompass the groove cheek on the rear side, there is the further advantage that the claws hold on the groove cheek that tapers outwards or becomes thicker as a result of elasticity and precision. You can also use the claws in front of the Position the respective wooden panel on the groove cheek without it falling off easily, and then insert the wooden panel with its spring into the groove of the neighboring panel and position it on the substructure and fasten it with the claws.

Bevorzugte Ausgestaltungen der Erfindung sind in den An­sprüchen 2 und 3 angegeben.Preferred embodiments of the invention are specified in claims 2 and 3.

Die Erfindugn bezieht sich ferner auf die Holzpaneele an sich, die so ausgebildet sind, daß sie die Erstellung von Nut-Feder-Verbindungen vorstehend beschriebenen Art mit entsprechenden Nachbarpaneelen ermöglichen, vgl. Anspruch 4.The invention also relates to the wooden panels themselves, which are designed in such a way that they enable the tongue-and-groove connections described above to be created with corresponding neighboring panels, cf. Claim 4.

Die Erfindung und Weiterbildungen der Erfindung werden im folgenden anhand von Ausführungsbeispielen noch näher erläutert. Es zeigen:

  • Fig. 1 im Schnitt die Ränder von zwei Verkleidungs­paneelen im Zustand der Annäherung bei der Montage;
  • Fig. 2 im Schnitt die Ränder von zwei im einzelnen etwa anders gestalteten Verkleidungspaneelen im fertig montierten Zustand.
The invention and further developments of the invention are explained in more detail below on the basis of exemplary embodiments. Show it:
  • Figure 1 in section, the edges of two cladding panels in the state of approach during assembly.
  • Fig. 2 in section, the edges of two individually differently designed cladding panels in the fully assembled state.

Das in Fig. 1 rechte Paneel 2 hat in seinem linken Rand eine Nut 4, die senkrecht zur Zeichenebene entlang des Randes des Paneels 2 verläuft. Die in Fig. 1 obere Wand bzw. Begrenzungsfläche 6 der Nut 4 ist parallel zur Rückfläche 8 und zur Vorderfläche 10 des Paneels. Der im Schnitt halbkreisförmige Nutgrund ist mit 12, und die nach links weisende Nutausmündung ist mit 14 bezeichnet. Die in Fig. 1 untere Wand bzw. Begrenzungsfläche 16 der Nut 4 verläuft unter einem Winkel im Bereich von 8 bis 15° derart geneigt zu der Rückfläche 8, daß sich die Weite w der Nut 4, gemessen senkrecht zur Rückfläche 8, von der Nutausmündung 14 kontinuierlich in Richtung auf den Nutgrund 12 zu verringert. In der Fig. 1 unterhalb der Nut 4, also rückflächenseitig von der Nut 4, ragt der Rand des Paneels 2 weiter nach links als oberhalb der Nut 4, also vorderflächenseitig von der Nut 4. Dadurch ist ein Überstand 18 gebildet. Oberhalb der Nut 4 verläuft der Rand des Paneels 2 für ein Stück der Paneelhöhe recht­winklig zur Rückfläche 8 und zur Vorderfläche 10. Dann folgt eine zunächst konkave und dann konvexe Krümmung zum optisch ansprechenden, glatten Übergang in die Vorder­fläche 10.The panel 2 on the right in FIG. 1 has a groove 4 in its left edge which runs perpendicular to the plane of the drawing along the edge of the panel 2. The upper wall or boundary surface 6 of the groove 4 in FIG. 1 is parallel to the rear surface 8 and to the front surface 10 of the panel. The groove base, which is semicircular in section, is denoted by 12 and the groove opening pointing to the left is denoted by 14. The lower wall or boundary surface 16 of the groove 4 in FIG. 1 is inclined at an angle in the range from 8 to 15 ° to the rear surface 8 such that the width w of the groove 4, measured perpendicular to the rear surface 8, extends from the groove mouth 14 continuously reduced in the direction of the groove base 12. In FIG. 1 below the groove 4, that is to say on the rear surface side of the groove 4, the edge of the panel 2 projects further to the left than above the groove 4, that is to say on the front surface side of the groove 4. As a result, a protrusion 18 is formed. Above the groove 4, the edge of the panel 2 runs at right angles to the rear surface 8 and the front surface 10 for a piece of the panel height. Then there is an initially concave and then convex curvature for a visually appealing, smooth transition into the front surface 10.

Das in Fig. 1 linke Paneel 2 hat an seinem in Fig. 1 rechten Rand eine Feder 20, deren obere Oberfläche bzw. Begrenzungsfläche 22 ebenfalls parallel zur Rückseite 8 und zur Vorderseite 10 dieses Paneels 2 ist. Die untere Oberfläche bzw. Begrenzungsfläche 24 verläuft im wesent­lichen unter dem gleichen Winkel wie die untere Be­grenzungsfläche 16 der Nut 4 relativ zur Rückfläche 8 des zugeordneten Paneels 2. Die Höhe der Feder 22, gemessen waagerecht in Fig. 1, von der Federwurzel 26 zum freien Federende 28 ist im wesentlichen gleich der in Fig. 1 waagerecht gemessenen Tiefe der Nut 4 vom Nutgrund 12 zur Nutausmündung 14. Die in Fig. 1 vertikal, also senkrecht zur Rückfläche 8 und zur Vorderfläche 10, gemessene Dicke d der Feder 20 ist allerdings geringer als die Weite w der Nut 4, wobei man bei dieser Ausdrucks­weise Stellen der Feder 20 und der Nut 4 miteinander vergleicht, die jeweils mit gleichem Abstand von Nutgrund 12 und vom freien Federende 28 bzw. von der Nutausmündung 14 und von der Federwurzel 26 haben. Die obere Begrenzungs­fläche 6 der Nut 4 hat den gleichen Abstand von der Rückfläche 8 des rechten Paneels 2 wie die obere Begrenzungs­fläche 22 der Feder 20 des linken Paneels 2. Oberhalb der Feder 20 ist das linke Paneel 2 spiegelbildlich zum rechten Paneel 2 gestaltet. Unterhalb der Feder 20 springt der Rand des linken Paneels 2 weiter zurück als oberhalb der Feder 20, entsprechend dem Überstand 18 am rechten Paneel 2.The panel 2 on the left in FIG. 1 has a spring 20 on its right edge in FIG. 1, the upper surface or boundary surface 22 of which is also parallel to the rear 8 and front 10 of this panel 2. The lower surface or boundary surface 24 extends essentially at the same angle as the lower boundary surface 16 of the groove 4 relative to the rear surface 8 of the associated panel 2. The height of the spring 22, measured horizontally in FIG. 1, from the spring root 26 to the free one Spring end 28 is substantially equal to the depth of groove 4 measured horizontally in FIG. 1 from groove base 12 to groove opening 14. Thickness d of spring 20, measured vertically in FIG. 1, that is to say perpendicular to rear surface 8 and front surface 10, is, however, less than the width w of the groove 4, with this expression comparing points of the tongue 20 and the groove 4 with each other, each having the same distance from the groove base 12 and from the free tongue end 28 or from the groove mouth 14 and from the spring root 26. The upper boundary surface 6 of the groove 4 is at the same distance from the rear surface 8 of the right panel 2 as the upper boundary surface 22 of the tongue 20 of the left panel 2. Above the tongue 20, the left panel 2 is mirrored to the right panel 2. Below the spring 20, the edge of the left panel 2 springs back further than above the spring 20, corresponding to the overhang 18 on the right panel 2.

Man sieht, daß das linke Paneel 2 mit seiner Feder 20 in die Nut 4 des rechten Paneels 2 eingeführt werden kann, wobei im zusammengeschobenen Zustand zwischen den unteren Begrenzungsflächen 16 und 22 Spiel verbleibt. Man kann sich ferner unmittelbar vorstellen,daß dieses Einführen aufgrund des Spiels, unterstützt noch durch die im Schnitt halbkreisförmige Abrundung des freien Federendes 28 und den als Auflagefläche dienenden Überstand 18, außerordentlich leicht von statten geht, wobei anfänglich sogar ein Einführen der Feder 20 schräg von oben hinein in die Nut 4 möglich ist. Erforderlichenfalls kann man den rechten Rand des linken Paneels 2 zusätzlich am Übergang in die Rück­fläche leicht abrunden oder abschrägen.It can be seen that the left panel 2 can be inserted with its spring 20 into the groove 4 of the right panel 2, with play remaining between the lower boundary surfaces 16 and 22 when pushed together. One can also immediately imagine that this insertion is extremely easy due to the play, supported by the semi-circular rounding of the free spring end 28 and the overhang 18 serving as a support surface. initially even inserting the tongue 20 into the groove 4 obliquely from above. If necessary, you can also slightly round off or chamfer the right edge of the left panel 2 at the transition to the rear surface.

Die in Fig. 2 gezeigten Paneele 2 sind genau wie die Paneele 2 von Fig. 1 gestaltet, wobei lediglich statt der konkav-konvexen Abrundung am Übergang vom Rand in die Vorderfläche 10 von unten nach oben zunächst eine Abschrägung und dann nur eine konvexe Abrundung vor­genommen worden ist. Fig. 2 zeigt den zusammengeschobenen Zustand der beiden Paneele 2. Zwischen den Rändern der beiden Paneele 2 ist eine Befestigungskralle 26 zu sehen, die im Schnitt der Fig. 2 die Form eines liegenden, nach rechts offenen U mit einem unteren, waagerechten Verlängerungsschenkel nach links hat. Das U der Kralle 26 umgreift den Überstand 18 von oben, links und unten. Das linke Paneel 2 ruht auf dem nach links verlängerten, unteren Schenkel der Kralle 26. Die Kralle 26 ist von links her auf den Überstand 18 aufgeschoben und vor An­bringung des linken Paneels 2 durch den linken Ver­längerungsschenkel hindurch mit einem Nagel 28 an der tragenden Unterkonstruktion angenagelt. Alternativ ist es möglich, statt mit der Kralle 26 eine Befestigung des rechten Paneels 2 an der Unterkonstruktion dadurch vorzunehmen, daß man von oben her vor Anbringung des linken Paneels 2 durch den Überstand 18 mit einem Nagel schräg hindurchnagelt. Da der Rand des rechten Paneels weiter vorsteht, ist diese Nagelung sehr einfach möglich. Der obere, nahezu waagerechte Schenkel der Kralle 26 findet im Freiraum zwischen der Feder 20 und der unteren Begrenzungsfläche 16 der Nut 4 Platz.The panels 2 shown in FIG. 2 are designed in exactly the same way as the panels 2 from FIG. 1, except that instead of the concave-convex rounding at the transition from the edge to the front surface 10 from bottom to top, first a bevel and then only a convex rounding is carried out has been. FIG. 2 shows the pushed-together state of the two panels 2. Between the edges of the two panels 2, a fastening claw 26 can be seen, which in the section of FIG. 2 has the shape of a lying U that is open to the right with a lower, horizontal extension leg to the left Has. The U of the claw 26 engages around the overhang 18 from above, left and below. The left panel 2 rests on the lower leg of the claw 26, which is elongated to the left. The claw 26 is pushed onto the overhang 18 from the left and nailed to the supporting substructure with a nail 28 through the left extension leg before attachment of the left panel 2 . Alternatively, it is possible, instead of using the claw 26, to fix the right panel 2 to the substructure by nailing at an angle from above before attaching the left panel 2 through the overhang 18 with a nail. Since the edge of the right panel protrudes further, this nailing is very easy. The upper, almost horizontal leg of the claw 26 takes place in the space between the spring 20 and the lower boundary surface 16 of the groove 4.

Da die Rückflächen 8 der Paneele 2 an der Unterkonstruktion fixiert sind und die oberen Begrenzungsflächen 6 und 22 einen gleichen Abstand von den Rückflächen 8 haben, ist trotz des unteren Spiels zwischen der Feder 20 und der unteren Nutbegrenzungsfläche eine Festlegung der Relativ­lage der beiden Paneele 2 in Richtung senkrecht zu den Rückflächen 8 gegeben. Die Feder 20 und die Nut 4 sind aus dem Material der Paneele 2 herausgefräst. Bei der gezeichneten Gestaltung ist eine Schrägeinführung des linken Paneels unter einem Winkel von 45° möglich.Since the rear surfaces 8 of the panels 2 are fixed to the substructure and the upper boundary surfaces 6 and 22 are equidistant from the rear surfaces 8, the relative position of the two panels 2 is fixed in spite of the lower play between the tongue 20 and the lower groove boundary surface Given direction perpendicular to the rear surfaces 8. The tongue 20 and the groove 4 are milled out of the material of the panels 2. In the drawn design, an inclined insertion of the left panel is possible at an angle of 45 °.

Der beschriebene Überstand 18 hat den weiteren Vorteil, daß überall bei der mit den Paneelen 2 erstellten Verkleidung Durchblicköffnungen durch die Stoßfugen zwischen benachbarten Paneelen 2 verhindert sind, auch dort wo dieser Überstand 18 an der Paneelecke wegen des Übergangs in einen mit Feder 20 versehenen Rand weggefräst ist, weil entweder eine Feder 20 oder ein Überstand 18 überall die Stoßfugen zwischen benach­barten Paneelen 2 überdecken, und zwar auch bei Schwindungen des Holzes der Paneele 2 und dadurch größer werdenden Stoßfugen. Zu derartigen Situationen kommt es bei Paneelen, die an zwei aneinander anschließenden Rän­dern jeweils mit Nut und an den anderen zwei aneinander an­schließenden Rändern jeweils mit Feder ausqebildet sind.The protrusion 18 described has the further advantage that viewing openings through the butt joints between adjacent panels 2 are prevented everywhere in the lining created with the panels 2, even where this protrusion 18 is milled away at the corner of the panel because of the transition into an edge provided with spring 20 is because either a spring 20 or a projection 18 cover the butt joints between adjacent panels 2 everywhere, even when the wood of the panels 2 shrinks and the butt joints become larger as a result. Such situations occur with panels which are each formed with a groove on two adjoining edges and with a tongue on the other two adjoining edges.

Die Zeichnungsfiguren sind maßstäblich im Maßstab 2:1 für 19 mm starke Paneele. Wegen der Abmessungen an den Rändern der Paneele und der Abmessungen der Nut 4 und der Feder 20 wird ausdrücklich auf die Zeichnungs­figuren hingewiesen.The drawing figures are to scale 2: 1 for 19 mm thick panels. Because of the dimensions at the edges of the panels and the dimensions of the groove 4 and the tongue 20, reference is expressly made to the drawing figures.

Die Federn und die Nuten bei dem erfindungsgemäßen Paneel können prägnant als keilförmig, ggf. am Ende abgerundet, bezeichnet werden.The tongues and the grooves in the panel according to the invention can be succinctly described as wedge-shaped, possibly rounded at the end.

Die gezeichneten Ausführungsbeispiele können so abge­wandelt sein, daß bei keilförmiger Feder 4 die Nut 20 die Fläche 16 parallel zur Fläche 6 im Abstand der Nutausmündung 14 hat oder daß bei keilförmiger Nut 20 die Feder 4 die Fläche 24 parallel zur Fläche 22 hat.The illustrated exemplary embodiments can be modified such that, in the case of a wedge-shaped tongue 4, the groove 20 has the surface 16 parallel to the surface 6 at a distance from the groove opening 14, or that, in the case of a wedge-shaped groove 20, the tongue 4 has the surface 24 parallel to the surface 22.
