Eine derartige Bodendiele ist bekannt aus dem Patent EP 3 177 783 B1 . Die bekannte Bodendiele weist ein flaches Rechteckrohrhohlprofil auf, von dessen einander abgewandten niederen Seiten leistenförmige Stege auskragen, das heißt zur Seite abstehen. Die einander abgewandten niederen Seiten der Bodendiele bilden Dielenränder, die Dielenrändern benachbarter Bodendielen zugewandt sind. Zwei auskragende Stege an einem Dielenrand bilden eine Art Federklammer, die zwei auskragende Stege an einem zugewandten Dielenrand einer benachbarten Bodendiele oben und unten übergreifen, so dass die benachbarten Bodendielen vertikal in einer Höhe zueinander ausgerichtet sind. Ein oberer Steg an einem Dielenrand weist eine Wasserablaufrinne auf, die einen oberen Steg am zugewandten Dielenrand einer benachbarten Diele untergreift, um Regen und anderes auf die Bodendielen gelangendes Wasser in Längsrichtung der Bodendielen abzuleiten.Such a floorboard is known from the patent EP 3 177 783 B1 . The well-known floorboard has a flat, rectangular tubular hollow profile, from the lower sides of which, facing away from one another, strip-shaped webs cantilever, that is to say protrude to the side. The opposite lower sides of the floorboard form board edges that face board edges of adjacent floorboards. Two projecting webs on one floorboard edge form a kind of spring clip, which overlaps two projecting webs on a facing floorboard edge of an adjacent floorboard at the top and bottom, so that the adjacent floorboards are aligned vertically at the same height as one another. An upper web on one edge of the floorboard has a water drainage channel, which reaches under an upper web on the facing edge of the floorboard of an adjacent floorboard in order to drain off rain and other water that gets onto the floorboards in the longitudinal direction of the floorboards.

An einander abgewandten Dielenrändern weist die Bodendiele Verbindungsanordnungen zum Verbinden benachbarter, in einer gemeinsamen Ebene parallel nebeneinander angeordneter Bodendielen auf. Die einander abgewandten Dielenränder einer Bodendiele sind Dielenrändern benachbarter Bodendielen zugewandt. Eine erste Verbindungsanordnung an einem ersten Dielenrand der Bodendiele weist einen auskragenden ersten oberen Steg und einen auskragenden unteren Steg auf. "Oben" und "unten" beziehen sich auf eine vorgesehene Gebrauchslage der Bodendielen. "Auskragen" bedeutet, dass die Stege vom Hohlprofil zur Seite nach außen in Richtung einer benachbarten Bodendiele abstehen. Vorzugsweise befindet sich der obere Steg an einer Oberseite und der untere Steg an einer Unterseite der Bodendiele, insbesondere sind die Stege bündig mit der Oberseite und der Unterseite der Bodendiele.On the board edges facing away from one another, the floor board has connecting arrangements for connecting adjacent floor boards arranged parallel next to one another in a common plane. The plank edges of a floor plank facing away from each other face plank edges of adjacent floor planks. A first connection arrangement on a first plank edge of the floor plank has a cantilevered first upper web and a cantilevered lower web. "Top" and "bottom" refer to an intended usage position of the floorboards. "Protruding" means that the webs protrude from the hollow profile to the side outwards in the direction of an adjacent floorboard. The upper web is preferably located on an upper side and the lower web on an underside of the floorboard; in particular, the webs are flush with the upper side and the underside of the floorboard.

Eine zweite Verbindungsanordnung an einem dem ersten Dielenrand abgewandten zweiten Dielenrand der Bodendiele weist einen auskragenden zweiten oberen Steg und einen auskragenden mittleren Steg auf. Der obere Steg befindet sich vorzugsweise an der Oberseite der Bodendiele und der mittlere Steg in einer Höhe zwischen den oberen Stegen und dem unteren Steg, das heißt zwischen der Oberseite und der Unterseite der Bodendiele.A second connection arrangement on a second edge of the floorboard facing away from the first edge of the floorboard has a projecting second upper web and a projecting central web. The top ridge is preferably at the top of the floorboard and the middle ridge is at a level between the top ridges and the bottom ridge, ie between the top and bottom of the floorboard.

Die Stege sind insbesondere leistenförmig und erstrecken sich in gleicher Lage bezüglich des Hohlprofils und mit gleichem Querschnitt über die Länge der Bodendiele.The webs are in particular strip-shaped and extend in the same position with respect to the hollow profile and with the same cross-section over the length of the floorboard.

Der erste obere Steg weist eine Tropfleiste, beispielsweise einen nach unten abstehenden Wulst oder Rippe auf, die in eine Wasserablaufrinne am zweiten oberen Steg am zweiten Dielenrand einer benachbarten Bodendiele ragt, wenn die beiden Bodendiele in einer gemeinsamen Ebene angeordnet und miteinander verbunden sind. Der zweite Dielenrand der benachbarten Bodendiele ist dem ersten Dielenrand der verbundenen einen Bodendiele zugewandt. Auf die Bodendiele gelangendes Wasser, das quer zur Bodendiele über deren Oberseite abläuft, gelangt über die Tropfleiste in die Wasserablaufrinne, die das Wasser in Längsrichtung der Bodendiele ableitet. Die Wasserablaufrinne steht bezüglich des Hohlprofils nach außen von dem zweiten oberen Steg ab und ist gegenüber dem zweiten oberen Steg nach unten versetzt, so dass die Wasserablaufrinne bei verbundenen Bodendielen die Tropfleiste der einen Bodendiele untergreift. Beispielsweise ist die Wasserablaufrinne durch eine Z-förmige Kröpfung, also eine doppelte Abwinklung, am zweiten oberen Steg nach unten versetzt. Die Tropfleiste und die Wasserablaufrinne verlaufen in der Längsrichtung der Bodendiele.The first top web has a drip rail, such as a downwardly projecting bead or rib, which protrudes into a water drainage channel on the second top web at the second plank edge of an adjacent floorboard when the two floorboards are arranged in a common plane and joined together. The second plank edge of the adjacent floor plank faces the first plank edge of the connected one floor plank. Water that gets onto the floorboard, which runs off across the top of the floorboard, reaches the water drainage channel via the drip rail, which drains the water in the longitudinal direction of the floorboard. With respect to the hollow profile, the water drainage channel protrudes outwards from the second upper web and is offset downwards relative to the second upper web, so that the water drainage channel reaches under the drip strip of one floor board when the floor boards are connected. For example, the water drainage channel is offset downwards by a Z-shaped bend, i.e. a double bend, on the second upper web. The drip strip and the water drainage channel run in the longitudinal direction of the floorboard.

Der untere Steg, der unter dem ersten oberen Steg am ersten Dielenrand vom Hohlprofil der Bodendiele auskragt, weist eine von außen in Richtung des Hohlprofils ansteigende ebene oder beispielsweise auch konkav oder konvex gewölbte Schrägfläche mit einer parallel zu dem Dielenrand, das heißt in Längsrichtung der Bodendiele verlaufenden Schnapprinne auf. Die Schnapprinne kann einen runden, V-förmigen, eckigen und grundsätzlich beliebigen Querschnitt aufweisen. Beim Verbinden zweier Bodendielen schnappt ein Schnappwulst am mittleren Steg am zweiten Dielenrand der benachbarten Bodendiele in die Schnapprinne in der Schrägfläche des unteren Stegs am zugewandten ersten Dielenrand der einen Bodendiele ein, so dass die beiden Bodendielen miteinander verbunden sind. Vorgesehen ist eine Lösbarkeit der Bodendielen durch Ausschnappen des Schnappwulstes aus der Schnapprinne. Der Schnappwulst verläuft wie die Schnapprinne in der Längsrichtung der Bodendiele und weist beispielsweise einen zylindrischen Querschnitt auf. Andere Querschnittsformen des Schnappwulstes sind möglich.The lower web, which protrudes from the hollow profile of the floorboard below the first upper web on the first edge of the floorboard, has a flat surface or, for example, a concave or convex curved surface that rises from the outside in the direction of the hollow profile, with a surface parallel to the edge of the floorboard, i.e. in the longitudinal direction of the floorboard running snap channel. The snap channel can have a round, V-shaped, angular and basically any cross-section. When connecting two floorboards, a snap bead on the middle web on the second board edge of the adjacent floorboard snaps into the snap channel in the inclined surface of the lower web on the facing first board edge of one floorboard, so that the two floorboards are connected to one another. Provision is made for the floorboards to be detachable by snapping the snap bead out of the snap channel. The snap bead runs like the snap channel in the Longitudinal direction of the floorboard and has, for example, a cylindrical cross section. Other cross-sectional shapes of the snap bead are possible.

Bei in der gemeinsamen Ebene angeordneten und miteinander verbundenen Bodendielen liegt die Wasserablaufrinne am zweiten oberen Steg am zweiten Dielenrand der einen Bodendiele unten am ersten oberen Steg am zugewandten ersten Dielenrand der benachbarten Bodendiele an. Vorzugsweise liegt die Wasserablaufrinne federnd beziehungsweise mit einer Vorspannung unten an dem ersten oberen Steg an. Dadurch sind die benachbarten Bodendielen in gleicher Höhe zueinander ausgerichtet. Außerdem hält die Anlage der Wasserablaufrinne der benachbarten Bodendiele unten am ersten oberen Steg der einen Bodendiele den Schnappwulst in der Schnapprinne.When floorboards are arranged and connected to one another in the common plane, the water drainage channel rests on the second upper web on the second floorboard edge of one floorboard below on the first upper web on the facing first floorboard edge of the adjacent floorboard. Preferably, the water drainage channel rests resiliently or with a prestress at the bottom on the first upper web. As a result, the adjacent floorboards are aligned at the same height. In addition, the installation of the water drainage channel of the adjacent floorboard keeps the snap bead in the snap channel at the bottom of the first upper web of one floorboard.

Zum Verbinden zweier Bodendielen werden die beiden Bodendielen in einem Winkel zueinander mit ihren einander zugewandten Dielenrändern so aneinander angesetzt, dass die Tropfleiste am ersten oberen Steg am ersten Dielenrand der benachbarten Bodendiele in die Wasserablaufrinne am zweiten oberen Steg am zugewandten zweiten Dielenrand der einen Bodendiele gelangt. Die in die Wasserablaufrinne der benachbarten Bodendiele greifende Tropfleiste der einen Bodendiele bildet zusammen mit der Wasserablaufrinne eine Art Scharnier, um das die beiden Bodendielen zum Verbinden aus der abgewinkelten Stellung in die gemeinsame Ebene schwenkbar sind.To connect two floorboards, the two floorboards are placed at an angle to one another with their facing board edges in such a way that the drip rail on the first upper web on the first board edge of the adjacent floorboard reaches the water drainage channel on the second upper web on the facing second board edge of one floorboard. The drip rail of one floor board, which reaches into the water drainage channel of the adjacent floor board, forms a kind of hinge together with the water drainage channel, around which the two floor boards can be pivoted from the angled position into the common plane for connection.

Beim Schwenken zum Verbinden der beiden Bodendielen gelangt der Schnappwulst am mittleren Steg am zweiten Dielenrand der einen Bodendiele auf die Schrägfläche des unteren Stegs am ersten Dielenrand der benachbarten Bodendiele und gleitet auf der Schrägfläche, bis er in die Schnapprinne in der Schrägfläche einschnappt, wenn die beiden Bodendielen in die gemeinsame Ebene gelangen.When swiveling to connect the two floorboards, the snap-in bead on the middle web on the second board edge of one floorboard reaches the inclined surface of the lower web on the first board edge of the adjacent floorboard and slides on the inclined surface until it snaps into the snap channel in the inclined surface when the two Floor boards get into the common plane.

Der mittlere Steg am zweiten Dielenrand ist als vertikal, das heißt bezüglich der Bodendiele nach oben und unten federnder Federsteg ausgebildet, der eine vertikale Federkraft auf die Schrägfläche des unteren Stegs am zugewandten zweiten Dielenrand der benachbarten Bodendiele ausübt und die Wasserablaufrinne am zweiten oberen Steg am zweiten Dielenrand der benachbarten Bodendiele federnd von unten gegen den ersten oberen Steg am ersten Dielenrand der einen Bodendiele drückt. Dadurch wird der Schnappwulst federnd in der Schnapprinne gehalten und die Bodendielen werden vertikal aneinander ausgerichtet, so dass die Oberseiten und die Unterseiten in einer Ebene parallel nebeneinander angeordneter und miteinander verbundener Bodendielen bündig sind.The central web on the second board edge is designed as a vertical spring bar, that is, with respect to the floor board, springs up and down and exerts a vertical spring force on the inclined surface of the lower web on the facing second Board edge of the adjacent floor board exerts and the water drainage channel on the second upper web on the second board edge of the adjacent floor board resiliently from below against the first upper web on the first board edge of a floor board presses. As a result, the snap bead is held resiliently in the snap channel and the floorboards are aligned vertically with one another, so that the tops and bottoms are flush in a plane of floorboards arranged parallel next to one another and connected to one another.

Ein Versatz der Wasserablaufrinne nach unten am zweiten oberen Steg am zweiten Dielenrand der einen Bodendiele bildet bei einer Ausgestaltung der Erfindung eineIn one embodiment of the invention, an offset of the water drainage channel downwards on the second upper web on the second plank edge of one floor plank forms a

Anlage für den ersten oberen Steg am zugewandten zweiten Dielenrand der benachbarten Bodendiele. Werden die beiden Bodendielen zum Verbinden in dem Winkel zueinander aneinander angesetzt, gelangt der erste obere Steg am ersten Dielenrand der benachbarten Bodendiele in Anlage an den die Anlage bildenden Versatz der Wasserablaufrinne nach unten am zweiten oberen Steg der einen Bodendiele. Dabei richten sich die Bodendielen zueinander aus. Wird der zweite obere Steg der einen Bodendiele beim Schwenken der beiden Bodendielen in die gemeinsame Ebene anliegend an der Anlage gehalten, gelangt der Schnappwulst wie vorgesehen auf die Schrägfläche und in die Schnapprinne. Der die Anlage bildenden Versatz der Wasserablaufrinne bildet eine Schwenkführung zum Verbinden der beiden Bodendielen.System for the first upper web on the facing second plank edge of the adjacent floor plank. If the two floorboards are attached to each other at the angle for connecting, the first upper web on the first floorboard edge of the adjacent floorboard comes into contact with the offset of the water drainage channel forming the system downwards on the second upper web of one floorboard. The floorboards align with each other. If the second upper web of one floorboard is held in contact with the system when the two floorboards are swiveled into the common plane, the snap-in bead reaches the inclined surface and into the snap-in channel as intended. The offset of the water drainage channel that forms the system forms a pivoting guide for connecting the two floor boards.

In bevorzugter Ausgestaltung der Erfindung ragt die Tropfleiste der benachbarten Bodendiele frei in die Wasserablaufrinne der einen Bodendiele, wenn die beiden Bodendielen in der gemeinsamen Ebene angeordnet und miteinander verbunden sind. Das heißt die Tropfleiste der benachbarten Bodendiele berührt weder den zweiten oberen Steg noch die Wasserablaufrinne der einen Bodendiele, wenn die beiden Bodendielen in der gemeinsamen Ebene angeordnet und miteinander verbunden sind. Beim Schwenken der beiden Bodendielen zum Verbinden bildet die in die Wasserablaufrinne der einen Bodendiele greifende Tropfleiste der benachbarten Bodendiele zusammen mit der Wasserablaufrinne wie gesagt eine Art Scharnier.In a preferred embodiment of the invention, the drip strip of the adjacent floorboard protrudes freely into the water drainage channel of one floorboard when the two floorboards are arranged in the same plane and connected to one another. This means that the drip rail of the adjacent floorboard touches neither the second upper web nor the water drainage channel of one floorboard when the two floorboards are arranged in the common plane and connected to one another. When pivoting the two floorboards for connection, the drip strip of the adjacent floorboard, which engages in the water drainage channel of one floorboard, forms a kind of hinge together with the water drainage channel, as mentioned.

Eine Ausgestaltung der Erfindung sieht vor, dass die Wasserablaufrinne konvex nach oben gewölbt ist und in Richtung des Hohlprofils der Bodendiele abfällt.An embodiment of the invention provides that the water drainage channel is curved convexly upwards and falls in the direction of the hollow profile of the floorboard.

Vorzugsweise kragt der untere Steg weiter aus als der erste obere Steg, das heißt von oben auf die Bodendiele gesehen steht der untere Steg seitlich unter dem oberen Steg vor. In einem nicht von dem ersten oberen Steg überdeckten Bereich weist der untere Steg bei einer Ausgestaltung der Erfindung eine Zentriersenkung zum Ansetzen einer Schraube und/oder einen nach oben stehenden Wasserrand auf. Die Zentriersenkung kann konisch sein, vorzugsweise ist sie eine in Längsrichtung der Bodendiele verlaufende, V-förmige Rinne zum Ansetzen eines Bohrers zum Bohren eines Schraubenlochs zur Befestigung der Bodendiele auf einem Untergrund. Der Wasserrand ist beispielsweise eine in der Längsrichtung der Bodendiele verlaufende Abwinklung oder Wölbung des unteren Stegs nach oben. Eventuell nicht von der Wasserrinne aufgefangenes Wasser wird bei dieser Ausgestaltung der Erfindung auf dem unteren Steg in der Längsrichtung der Bodendiele abgeleitet.The lower web preferably protrudes further than the first upper web, that is to say that, viewed from above onto the floorboard, the lower web projects laterally under the upper web. In one embodiment of the invention, in a region not covered by the first upper web, the lower web has a centering countersink for attaching a screw and/or an upwardly projecting water edge. The centering countersink can be conical, preferably it is a V-shaped groove running in the longitudinal direction of the floorboard for applying a drill bit Drilling a screw hole to attach the floorboard to a substructure. The water edge is, for example, an upward bend or curvature of the lower web running in the longitudinal direction of the floorboard. In this embodiment of the invention, any water that is not caught by the gully is drained off on the lower web in the longitudinal direction of the floorboard.

Eine Ausgestaltung der Erfindung sieht eine zweite Wasserablaufrinne am ersten Dielenrand der Bodendiele unter dem ersten oberen Steg vor, die tiefer an der Bodendiele, also näher an der Unterseite der Bodendiele angeordnet ist als die Wasserablaufrinne am zweiten oberen Steg am abgewandten zweiten Dielenrand der Bodendiele. Auch die zweite Wasserablaufrinne hat die Funktion, Wasser, das unter die Wasserablaufrinne am ersten oberen Steg gelangt, in Längsrichtung der Bodendiele abzuleiten.One embodiment of the invention provides a second water drainage channel on the first edge of the floorboard under the first upper web, which is arranged lower on the floorboard, i.e. closer to the underside of the floorboard, than the water drainage channel on the second upper web on the second edge of the floorboard facing away. The second water drainage channel also has the function of draining water that gets under the water drainage channel on the first upper web in the longitudinal direction of the floorboard.

Der mittlere Steg ist bei einer Ausgestaltung der Erfindung in einer Querrichtung der Bodendiele bogenförmig gewölbt.In one embodiment of the invention, the middle web is arched in a transverse direction of the floorboard.

Zum Befestigen beispielsweise einer Blende an einer Stirnseite der Bodendiele sieht eine Ausgestaltung der Erfindung einen in der Längsrichtung der Bodendiele verlaufenden Schraubkanal zum Einschrauben einer Schraube auf.For fastening, for example, a panel to an end face of the floorboard, one embodiment of the invention provides a screw channel running in the longitudinal direction of the floorboard for screwing in a screw.

Eine Ausgestaltung der Erfindung sieht eine Aussteifung für den zweiten oberen Steg vor, die von innen nach außen schräg nach oben vom Hohlprofil zum zweiten oberen Steg und/oder dessen Wasserablaufrinne verläuft. Durch die Aussteifung bildet die Wasserablaufrinne ein in vertikaler Richtung der Bodendiele stabiles Widerlager zur Anlage von unten an dem ersten oberen Steg am ersten Dielenrand der benachbarten Bodendiele.One embodiment of the invention provides a stiffening for the second upper web, which runs obliquely upwards from the inside to the outside from the hollow profile to the second upper web and/or its water drainage channel. Due to the stiffening, the water drainage channel forms an abutment that is stable in the vertical direction of the floorboard for bearing from below on the first upper web on the first floorboard edge of the adjacent floorboard.

Sämtliche in der Beschreibung genannte und/oder der Zeichnung dargestellte Merkmale können einzeln für sich oder in jeder beliebigen Kombination bei Ausführungen der Erfindung verwirklicht sein. Ausführungen der Erfindung, die nicht alle, sondern nur einen Teil der Merkmale eines Anspruchs, auch des unabhängigen Anspruchs, aufweisen, sind möglich.All of the features mentioned in the description and/or shown in the drawing can be realized individually or in any combination in embodiments of the invention. Embodiments of the invention which do not have all but only some of the features of a claim, including those of the independent claim, are possible.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigen:

  • Figur 1 einen Querschnitt einer Bodendiele gemäß der Erfindung; und
  • Figuren 2a-c ein Verbinden zweier erfindungsgemäßer Bodendielen.
The invention is explained in more detail below with reference to an embodiment shown in the drawing. Show it:
  • figure 1 a cross-section of a floorboard according to the invention; and
  • Figures 2a-c connecting two floorboards according to the invention.

Die in der Zeichnung dargestellte, erfindungsgemäße Bodendiele 1 ist für einen Dielenboden aus in einer Ebene parallel nebeneinander angeordneten und miteinander verbundenen Bodendielen 1 vorgesehen. Die Bodendiele 1 ist durch Strangpressen aus Metall, beispielsweise aus einer Aluminiumlegierung hergestellt. Sie weist ein flaches Rechteckrohrhohlprofil 25 mit über eine Länge der Bodendiele 1 gleich bleibendem Querschnitt auf. Das Rechteckrohrhohlprofil 25 der Bodendiele 1 weist eine Oberseite 2, eine Unterseite 3 und zwei niedrige Seiten 4 auf, die ungefähr 1/5 so hoch sind wie das Rechteckrohrhohlprofil 25 breit ist. Im Innern des Rechteckrohrhohlprofils 25 sind die Oberseite 2 und die Unterseite 3 durch vertikalen Stützstege 5 einstückig verbunden.The floorboard 1 according to the invention shown in the drawing is intended for a floorboard made of floorboards 1 arranged parallel next to one another and connected to one another in one plane. The floorboard 1 is made of metal, for example an aluminum alloy, by extrusion. It has a flat rectangular tubular hollow profile 25 with a cross section that remains the same over a length of the floorboard 1 . The rectangular tubular hollow profile 25 of the floorboard 1 has a top 2, a bottom 3 and two low sides 4, which are approximately 1/5 as high as the rectangular tubular hollow profile 25 is wide. Inside the rectangular tubular hollow profile 25, the upper side 2 and the lower side 3 are connected in one piece by vertical supporting webs 5.

Raumrichtungen wie "oben", "unten" und "vertikal" beziehen sich auf eine vorgesehene Gebrauchslage und in Figur 1 gezeichnete Lage der Bodendiele 1, bei der sich die Unterseite unten und die Oberseite oben befinden.Spatial directions such as "above", "below" and "vertical" refer to an intended position of use and in figure 1 drawn position of the floorboard 1, in which the underside is down and the top is up.

Von den niedrigen Seiten 4 des Rechteckrohrhohlprofils 25 der Bodendiele 1 stehen Stege 6, 7, 8, 9 nach außen ab, was auch als Auskragen der Stege 6, 7, 8, 9 an in der Längsrichtung der Bodendiele 1 verlaufenden, einander abgewandten Dielenrändern 10, 11 der Bodendiele 1 aufgefasst werden kann. Die Stege 6, 7, 8, 9 bilden zwei Verbindungsanordnungen 12, 13 an den beiden Dielenrändern 10, 11 zum Verbinden benachbarter Bodendielen 1.Webs 6, 7, 8, 9 protrude outwards from the low sides 4 of the rectangular tubular hollow profile 25 of the floorboard 1, which can also be seen as a cantilever of the webs 6, 7, 8, 9 on opposite board edges 10 , 11 of the floorboard 1 can be understood. The webs 6, 7, 8, 9 form two connecting arrangements 12, 13 on the two board edges 10, 11 for connecting adjacent floorboards 1.

An einem ersten der beiden Dielenränder 10 kragt ein erster oberer Steg 6 und ein unterer Steg 7 aus. Der obere Steg 6 ist bündig mit der Oberseite 2 und der untere Steg 7 ist bündig mit der Unterseite 3 der Bodendiele 1. Der untere Steg 7 kragt weiter aus als der erste obere Steg 6, das heißt der untere Steg 7 steht weiter von der niedrigen Seite 4 des Rechteckrohrhohlprofils 25 der Bodendiele 1 ab als der erste obere Steg 6, so dass senkrecht auf die Oberseite 2 der Bodendiele 1 gesehen der erste obere Steg 6 den unteren Steg nur teilweise überdeckt. Die Stege 6, 7, 8, 9 sind streifenförmig mit über die Länge der Bodendiele 1 gleichbleibender Lage in Bezug zur Bodendiele 1 und gleichbleibendem Querschnitt.A first upper web 6 and a lower web 7 protrude from a first of the two board edges 10 . The upper web 6 is flush with the top 2 and the lower web 7 is flush with the underside 3 of the floorboard 1. The lower web 7 protrudes further than the first upper web 6, that is, the lower web 7 is further from the low Page 4 of the rectangular tubular hollow profile 25 of the floorboard 1 from as the first upper web 6, so that viewed perpendicularly to the top 2 of the floorboard 1, the first upper web 6 only partially covers the lower web. The webs 6, 7, 8, 9 are strip-shaped with a constant position over the length of the floorboard 1 in relation to the floorboard 1 and a constant cross section.

Der erste obere Steg 6 weist eine niedrige, in der Längsrichtung der Bodendiele 1 verlaufende Tropfleiste 14 an einem freien, das heißt dem Rechteckrohrhohlprofil 25 fernen Längsrand des oberen Stegs 6 auf, die nach unten, das heißt in Richtung des unteren Stegs 7 gerichtet ist.The first upper web 6 has a low drip rail 14 running in the longitudinal direction of the floorboard 1 on a free longitudinal edge of the upper web 6, i.e. remote from the rectangular tubular hollow profile 25, which is directed downwards, i.e. in the direction of the lower web 7.

Der untere Steg 7 weist eine Schrägfläche 15 an seiner dem ersten oberen Steg 6 zugewandten Oberseite auf, der von außen nach innen, das heißt in Richtung der niedrigen Seite 4 des Rechteckrohrhohlprofils 25 ansteigt, das heißt ihren Abstand vom ersten oberen Steg 6 verkleinert. Die Schrägfläche 15 weist eine in der Längsrichtung der Bodendiele 1 verlaufende Schnapprinne 16 mit im Ausführungsbeispiel runden Querschnitt auf.The lower web 7 has an inclined surface 15 on its upper side facing the first upper web 6, which increases from the outside inwards, i.e. in the direction of the low side 4 of the rectangular tubular hollow profile 25, i.e. reduces its distance from the first upper web 6. The sloping surface 15 has a snap channel 16 running in the longitudinal direction of the floorboard 1 and having a round cross-section in the exemplary embodiment.

Außerhalb der Überdeckung durch den ersten oberen Steg 6 weist der untere Steg 7 eine konstante Dicke auf. Ein freier, dem Rechteckrohrhohlprofil 25 ferner Rand des unteren Stegs 7 ist rechtwinklig nach oben abgewinkelt und bildet einen Wasserrand 17.Outside of the overlapping of the first upper web 6, the lower web 7 has a constant thickness. A free edge of the lower web 7 that is farther from the rectangular tubular hollow profile 25 is angled upwards at right angles and forms a water edge 17.

Zwischen dem Wasserrand 17 und der Schrägfläche 15 weist der untere Steg 7 eine in der Längsrichtung der Bodendiele 1 verlaufende V-förmige Rinne als Zentriersenkung 18 für nicht dargestellte Schrauben zur Befestigung der Bodendiele 1 auf einer Unterlage auf. An der Zentriersenkung 18 kann ein Bohrer zum Bohren von Schraubenlöchern für die Schrauben angesetzt oder es werden die Schrauben direkt an der Zentriersenkung 18 angesetzt.Between the water edge 17 and the inclined surface 15, the lower web 7 has a V-shaped groove running in the longitudinal direction of the floorboard 1 as a centering countersink 18 for screws, not shown, for fastening the floorboard 1 to a base. A drill for drilling screw holes for the screws can be attached to the centering counterbore 18 or the screws are attached directly to the centering counterbore 18 .

Der erste obere Steg 6 und der untere Steg 7 bilden eine erste Verbindungsanordnung 12 der beiden Verbindungsanordnungen 12, 13 oder einen Teil der ersten Verbindunganordnung 12 am ersten Dielenrand 10.The first upper web 6 and the lower web 7 form a first connection arrangement 12 of the two connection arrangements 12, 13 or a part of the first connection arrangement 12 on the first board edge 10.

An einem dem ersten Dielenrand 10 abgewandten zweiten Dielenrand 11 kragen ein zweiter oberer Steg 8 und ein mittlerer Steg 9 aus, das heißt die Stege 8, 9 stehen nach außen zur Seite von der niedrigen Seite 4 des Rechteckrohrhohlprofils 25 der Bodendiele 1 ab. Der zweite obere Steg 8 ist bündig mit der Oberseite 2 der Bodendiele 1. Er weist an seinem dem Rechteckrohrhohlprofil 25 fernen Rand eine in der Längsrichtung der Bodendiele 1 verlaufende Wasserablaufrinne 19 auf. Die Wasserablaufrinne 19 ist über eine - im Ausführungsbeispiel - Z-förmige Kröpfung einstückig mit dem zweiten oberen Steg 8 verbunden und gegenüber dem zweiten oberen Steg 8 nach unten versetzt. Die Z-förmige Kröpfung beziehungsweise der Versatz der Wasserablaufrinne 19 gegenüber dem zweiten oberen Steg 8 nach unten bildet eine Anlage 20 für den ersten oberen Steg 6 beim Verbinden zweier Bodendielen 1. Die Wasserablaufrinne 19 ist konvex nach oben gewölbt und fällt von außen in Richtung des zweiten oberen Stegs 8 ab.On a second floorboard edge 11 facing away from the first floorboard edge 10, a second upper web 8 and a middle web 9 protrude, i.e. the webs 8, 9 protrude outwards to the side from the low side 4 of the rectangular tubular hollow profile 25 of the floorboard 1. The second upper web 8 is flush with the upper side 2 of the floorboard 1. On its edge remote from the rectangular tubular hollow profile 25, it has a water drainage channel 19 running in the longitudinal direction of the floorboard 1. The water drainage channel 19 is connected in one piece to the second upper web 8 and offset from the second upper web 8 downwards—in the exemplary embodiment—Z-shaped bend. The Z-shaped bend or the offset of the water drainage channel 19 downwards in relation to the second upper web 8 forms a contact 20 for the first upper web 6 when connecting two floorboards 1. The water drainage channel 19 curves convexly upwards and falls from the outside in the direction of the second upper web 8 from.

Unter dem zweiten oberen Steg 8 kragt ein mittlerer Steg 9 am zweiten Dielenrand 11 aus, der im Ausführungsbeispiel konvex nach unten gewölbt ist und einen im Ausführungsbeispiel zylinderförmigen Schnappwulst 21 an seinem freien äußeren Ende aufweist, der in der Längsrichtung der Bodendiele 1 verläuft. Der mittlere Steg 9 befindet sich in einer Höhe zwischen der Oberseite 2 und der Unterseite 3 der Bodendiele 1. Der mittlere Steg 9 ist elastisch als vertikal federnder Federsteg ausgebildet.Under the second upper web 8, a central web 9 protrudes from the second board edge 11, which is convexly curved downwards in the exemplary embodiment and has a snap-on bead 21, which is cylindrical in the exemplary embodiment, on its free outer edge Has end which runs in the longitudinal direction of the floorboard 1. The central web 9 is located at a height between the top 2 and the underside 3 of the floorboard 1. The central web 9 is designed to be elastic as a vertically resilient spring bar.

Von einer Stelle nahe der niedrigen Seite 4 des Rechteckrohrhohlprofils 25 der Bodendiele 1 verläuft eine Aussteifung 22 zur Z-förmigen Kröpfung, die die Wasserablaufrinne 19 dem zweiten oberen Steg 8 verbindet und dadurch den auskragenden zweiten oberen Steg 8 aussteift, so dass er nicht federt.A stiffener 22 runs from a point near the low side 4 of the rectangular tubular hollow profile 25 of the floorboard 1 to the Z-shaped bend, which connects the water drainage channel 19 to the second upper web 8 and thereby stiffens the cantilevered second upper web 8 so that it does not spring.

Der zweite obere Steg 8 und der mittlere Steg 9 bilden eine zweite Verbindungsanordnung 13 der beiden Verbindungsanordnungen 12, 13 oder Teil der zweiten Verbindungsanordnung 13 an dem dem ersten Dielenrand 10 mit der ersten Verbindungsanordnung 12 abgewandten zweiten Dielenrand 11 der Bodendiele 1.The second upper web 8 and the middle web 9 form a second connection arrangement 13 of the two connection arrangements 12, 13 or part of the second connection arrangement 13 on the second floorboard edge 11 of the floorboard 1 facing away from the first floorboard edge 10 with the first connection arrangement 12.

Zu einem Verbinden zweier benachbarter Bodendielen 1 werden die beiden Bodendielen 1 wie in Figur 2a zu sehen in einem Winkel zwischen ungefähr 90° und 45° zueinander so aneinander angesetzt, dass die Z-förmige Kröpfung, die die Wasserablaufrinne 19 einstückig und mit Versatz nach unten mit dem zweiten oberen Steg 8 am zweiten Dielenrand 11 einer Bodendiele 1 verbindet und die Anlage 20 bildet, gegen den freien Rand des ersten oberen Stegs 6 am ersten Dielenrand 10 einer benachbarten Bodendiele 1 stößt. Die in Figuren 2a bis c links gezeichnete Bodendiele 1 wird nachfolgend auch als die eine Bodendiele 1 und die rechts gezeichnete als benachbarte Bodendiele 1 bezeichnet werden. Die Anlage 20 und der freie Rand des zweiten oberen Stegs 8 bilden eine Art Scharnier, um das die eine Bodendiele 1 in Bezug auf die benachbarte Bodendiele 1 geschwenkt wird, um die beiden Bodendielen 1 miteinander zu verbinden. Beim Schwenken der Bodendielen 1 wird die Anlage 20 der einen Bodendiele 1 in Anlage am freien Rand des zweiten oberen Stegs 8 der benachbarten Bodendiele 1 gehalten.To connect two adjacent floorboards 1, the two floorboards 1 as in Figure 2a seen at an angle of between approximately 90° and 45° to one another in such a way that the Z-shaped bend that connects the water drainage channel 19 in one piece and offset downwards with the second upper web 8 on the second edge 11 of a floorboard 1 and the Plant 20 forms against the free edge of the first upper web 6 on the first board edge 10 of an adjacent floor board 1 abuts. In the Figures 2a to c The floorboard 1 drawn on the left will also be referred to below as one floorboard 1 and the one drawn on the right as the adjacent floorboard 1 . The system 20 and the free edge of the second upper web 8 form a kind of hinge about which one floorboard 1 is pivoted in relation to the adjacent floorboard 1 in order to connect the two floorboards 1 to one another. When the floorboards 1 are pivoted, the system 20 of one floorboard 1 is held in contact with the free edge of the second upper web 8 of the adjacent floorboard 1 .

Beim Anlegen der einen Bodendiele 1 mit ihrer Anlage 20 am freien Rand des zweiten oberen Stegs 8 der benachbarten Bodendiele 1 gelangt die Tropfleiste 14 am zweiten oberen Steg 8 der benachbarten Bodendiele 1 in die Wasserablaufrinne 19 der einen Bodendiele 1 und bildet mit dieser eine Art Scharnier, um die die eine Bodendiele 1 zum Verbinden mit der benachbarten Bodendiele 1 geschwenkt wird.When laying one floorboard 1 with its attachment 20 on the free edge of the second upper web 8 of the adjacent floorboard 1, the drip strip 14 on the second upper web 8 of the adjacent floorboard 1 reaches the water drainage channel 19 one floorboard 1 and forms with it a kind of hinge around which one floorboard 1 is pivoted for connection to the adjacent floorboard 1 .

Wie in Figur 2b zu sehen, gelangt beim Schwenken der einen Bodendiele 1 in Bezug zur benachbarten Bodendiele 1 der Schnappwulst 21 des mittleren Stegs 9 der einen Bodendiele 1 auf die Schrägfläche 15 an der Oberseite des unteren Stegs 7 der benachbarten Bodendiele 1 und gleitet auf der Schrägfläche 15 bis zur Schnapprinne 16 in der Schrägfläche 15, in die der Schnappwulst 21 einschnappt, wenn die beiden Bodendielen 1 wie in Figur 2c zu sehen in die gemeinsame Ebene geschwenkt werden. Die beiden Bodendielen 1 sind miteinander verbunden, die beiden Verbindungsanordnungen 12, 13 bilden die beschriebene Schnappverbindung.As in Figure 2b As can be seen, when one floorboard 1 is pivoted in relation to the adjacent floorboard 1, the snap-on bead 21 of the central web 9 of one floorboard 1 reaches the inclined surface 15 on the upper side of the lower web 7 of the adjacent floorboard 1 and slides on the inclined surface 15 up to the Snap channel 16 in the inclined surface 15, into which the snap bead 21 snaps when the two floorboards 1 as in Figure 2c can be seen panned into the common plane. The two floorboards 1 are connected to each other, the two connection arrangements 12, 13 form the snap connection described.

Befinden sich die beiden miteinander verbundenen Bodendielen 1 in der gemeinsamen Ebene, ragt die Tropfleiste 14 der benachbarten Bodendiele 1 frei in die Wasserablaufrinne 19 der einen Bodendiele 1, das heißt sie berührt - anders als während des Schwenkens der Bodendielen 1 - weder die Wasserablaufrinne 19 noch den ersten oberen Steg 6.If the two floorboards 1 connected to one another are in the same plane, the drip rail 14 of the adjacent floorboard 1 protrudes freely into the water drainage channel 19 of one floorboard 1, i.e. it touches - unlike when the floorboards 1 are pivoted - neither the water drainage channel 19 nor the first upper bar 6.

Vor dem Ansetzen der einen Bodendiele 1 an der benachbarten Bodendiele 1 zum Verbinden der beiden Bodendielen 1 wird die benachbarte Bodendiele 1 mit an der Zentriersenkung 18 angesetzten Schrauben durch den unteren Steg 7 auf einem Untergrund festgeschraubt (nicht dargestellt).Before attaching the one floorboard 1 to the adjacent floorboard 1 to connect the two floorboards 1, the adjacent floorboard 1 is screwed to the centering recess 18 with screws through the lower web 7 on a substrate (not shown).

Die Wasserablaufrinne 19 der einen Bodendiele 1 untergreift den ersten oberen Steg 6 der benachbarten Bodendiele 1, wenn die beiden Bodendielen 1 verbunden sind, so dass Regen oder anderes Wasser, das auf die Oberseite 2 der Bodendielen 1 gelangt und quer über die Bodendielen 1 fließt, an der Tropfleiste 14 in die Wasserablaufrinne 19 gelangt und in dieser in Längsrichtung der Bodendielen 1 abgeführt wird.The water drainage channel 19 of one floorboard 1 reaches under the first upper web 6 of the adjacent floorboard 1 when the two floorboards 1 are connected, so that rain or other water that reaches the upper side 2 of the floorboards 1 and flows across the floorboards 1 arrives at the drip rail 14 in the water drainage channel 19 and is discharged in this in the longitudinal direction of the floorboards 1.

Unter dem ersten oberen Steg 6 und über der Schrägfläche 15 kragt eine zweite Wasserablaufrinne 23 am ersten Dielenrand 10 vom Rechteckrohrhohlprofil 25 der Bodendiele 1 aus. Eventuell aus der Wasserablaufrinne 19 übertretendes Wasser gelangt in die darunter befindliche zweite Wasserablaufrinne 23 und wird in dieser in der Längsrichtung der Bodendielen 1 abgeführt.Under the first upper web 6 and above the inclined surface 15 cantilevers a second water drainage channel 23 on the first board edge 10 from the rectangular tubular hollow profile 25 of the Floor board 1 off. Any water overflowing from the water drainage channel 19 reaches the second water drainage channel 23 located underneath and is discharged in this in the longitudinal direction of the floorboards 1 .

Durch seinen Wasserrand 17 bildet der untere Steg 7 eine dritte Wasserablaufrinne für den Fall, dass auch aus der zweiten Wasserablaufrinne 23 Wasser austreten sollte.With its water edge 17, the lower web 7 forms a third water drainage channel in the event that water should also emerge from the second water drainage channel 23.

Der als vertikal federnde Federsteg ausgebildete mittlere Steg 9 drückt den Schnappwulst 21 federnd in die Schnapprinne 16, wodurch zum einen der Schnappwulst 21 in der Schnapprinne 16 eingeschnappt und die beiden Bodendielen 1 verbunden gehalten werden. Zum anderen drückt der als Federsteg ausgebildete mittlere Steg 9 die eine Bodendiele 1 an der Schrägfläche 15 der benachbarten Bodendiele 1 elastisch nach oben und die Wasserablaufrinne 19 der einen Bodendiele 1 gegen eine Unterseite des ersten oberen Stegs 6 der benachbarten Bodendiele 1. Dadurch werden die beiden verbundenen Bodendielen 1 vertikal aneinander ausgerichtet, so dass ihre Oberseiten 2 bündig sind.The central web 9 designed as a vertically resilient spring web presses the snap bead 21 resiliently into the snap channel 16, as a result of which the snap bead 21 is snapped into the snap channel 16 and the two floorboards 1 are kept connected. On the other hand, the central web 9 designed as a spring bar presses one floorboard 1 elastically upwards on the inclined surface 15 of the adjacent floorboard 1 and the water drainage channel 19 of one floorboard 1 against an underside of the first upper web 6 of the adjacent floorboard 1. This causes the two connected floorboards 1 aligned vertically with each other so that their tops 2 are flush.

An einem Innern des Rechteckrohrhohlprofils 25 zugewandten Innenseiten weisen die niedrigen Seiten 4 des Rechteckrohrhohlprofils 25 zylinderrohrförmige Schraubkanäle 24 auf, die in der Längsrichtung der Bodendiele 1 verlaufen. Im Ausführungsbeispiel weisen die Schraubkanäle 24 einen durchgehenden Längsschlitz auf. Sie sind zum Einschrauben nicht dargestellter, selbstschneidender Schrauben zur Befestigung beispielsweise einer ebenfalls nicht dargestellten Blende am Stirnende der Bodendiele 1 beziehungsweise am Stirnende des Dielenbodens auf, der aus den in einer Ebene parallel nebeneinander angeordneten und miteinander verbundenen Bodendielen 1 besteht.On inner sides facing the interior of the rectangular tubular hollow profile 25 , the low sides 4 of the rectangular tubular hollow profile 25 have screw channels 24 in the form of cylindrical tubes, which run in the longitudinal direction of the floorboard 1 . In the exemplary embodiment, the screw channels 24 have a continuous longitudinal slot. They are for screwing in self-tapping screws, not shown, for fastening, for example, a panel, also not shown, on the front end of the floorboard 1 or on the front end of the floorboard, which consists of the floorboards 1 arranged parallel to one another and connected to one another in one plane.
