Definitions
- the present invention relates to a hard floor panel for floating installation with the formation of a floor panel composite, in particular a laminate floor.
- Floor panels with tongue and groove profiles on the side edges for laying to form panels, such as laminate floors, are widely used and conventionally known.
- the tongue and groove profiles make it easy to lay floor panels to floor coverings.
- Such floor coverings can consist of wood fiber panels or plastic panels, for example.
- the floor panels are provided with a decorative layer and an abrasion-resistant surface layer.
- the tongue and groove profiles conventionally used have the disadvantage that gaps of different sizes are formed between the panels lying against one another. Dirt as well as moisture can penetrate into these gaps and lead to expansion or swelling of the base plate of the floor panel, in particular if wood-based panels are used as base plates. The expansion or swelling of the wood-based panel causes the surface layer to rise, so that the surface layer is exposed to increased abrasion.
- a floor panel for realizing a floor covering is known, coupling parts in the form of a groove and a tongue being provided on the edges of two opposite sides of the panels. Tongue and groove are designed in such a way that when two or more floor panels are joined together, a tension force is exerted on one another, which the floor panels forces one another.
- the tensioning force is brought about by an elastically bendable lip in the groove which is at least partially bent in the assembled state and in this way provides the aforementioned tensioning force.
- WO 2016/113706 A1 describes a hard floor panel for floating installation with the formation of a floor panel composite, the opposite side edges each being provided with tongue and groove profiles and a tongue with a joining surface in the first side edge and a groove with an upper lip in the second side edge a joining surface is provided.
- a floor panel in particular with a core made of a wood-based panel, a wood-based plastic panel or a plastic panel, with an upper side and a lower side and with side edges along the panel sides (i.e. along the long sides and transverse sides) is used for floating installation with the formation of a floor panel composite provided, whereby at least two floor panels are put together or connected to one another, the opposite side edges are provided with tongue and groove profiles, wherein a tongue and a joining surface are provided in a first side edge and a groove and a joining surface are provided in a second opposite side edge, wherein the tongue of the first side edge has an upper side and a lower side; wherein a projection with a contact surface is provided on the lower side of the spring; wherein the joining surface of the first side edge runs from the top of the floor panel to the upper tongue side and the joining surface is beveled; wherein the joining surface of the first side edge is inclined from the top of the floor panel inwardly away from the perpendicular away from the tongue so that the
- tension and line pressure Due to the combination of tension and line pressure according to the invention, it is now possible to avoid the formation of gaps between adjacent floor panels, and thus to reduce the entry of moisture and dirt into the floor covering.
- the line pressure results from the profile geometry and the pressure to be applied.

- the protrusion on the lower side of the tongue extends along the lower lip of the groove and engages the recess of the lower lip of the groove when two panels are coupled.
- the contact surfaces of the projection of the spring and the recess lie against one another.
- the tongue is precisely positioned against the upper side and the lower side of the groove, a pressure P being exerted on the upper lip of the groove. This pressure is not only absorbed by the upper lip, but by the entire structure, since the pressure can be transmitted through the spring and the lower lip.
- the clamping force by which the panels are joined and held is produced by the pressing pressure P.
- bevel of the joining surfaces or joining edges is to be understood as a bevel or inclination of the joining surfaces or joining edges from the top of the panel inwardly away from the vertical away from the tongue or towards the groove.
- the top of the panel and the respective joining surface of the side edges usually form a right angle (90 °); i.e. the top of the panel and the joining surface are arranged at right angles to one another.

- the upper side of the tongue is flat or flat and horizontal in relation to the panel upper side.
- the upper side of the groove (or lower side of the upper lip of the groove) is also arranged flat and horizontally, so that the tongue and groove can engage or can be pushed into one another without resistance.

- This bevel can also be described as a chamfer with an angle between 45-55 °.
- the projection provided on the lower side of the tongue extends along the lower lip of the groove.
- the projection engages in the recess of the lower lip of the groove in the coupled state of two panels.

- an additional space can form between the projection of the lower tongue side and the recess in the lower lip of the groove, which e.g. functions as a dust chamber.
- the size of the dust chamber can, for example, vary between the profiles in the panel longitudinal sides (longitudinal profile) and panel transverse sides (transverse profile).

- the pretension caused by the interaction of tongue and groove is optimally transferred to the upper side of the floor panel, with the joining surfaces of the tongue and groove profiles being pressed against one another in the engagement direction so that there is a line pressure at the contact point of the joining surfaces Formation of an angle between the joining surfaces comes.
- the invention is explained for rectangular floor panels that can be connected to one another both on their long sides and on their transverse sides or else only on one side.
- the present floor panels have a rectangular shape with side edges 10, 20 which extend along the longitudinal sides and transverse sides of the panel and are suitable for floating installation to form a floor panel.
- the floor panels typically have a length of one to two meters.
- the thickness of the panels can also vary, but is in Figures 1A-C and 2A-C described embodiments 4.5 mm.
- Each floor panel has on the opposite edges 10, 20 the tongue-and-groove profiles described in detail below, which enable 2 adjacent floor panels to be joined together.
- a tongue 11 is provided in a first side edge 10 and a groove 21 is provided in the second opposite side edge 20.
- Figure 1A shows a first spring profile, which is provided for a transverse side of the floor panel.
- the tongue 11 of the tongue profile of the first side edge 10 has an upper side 12 and a lower side 13.
- the distance of the tongue top 12 from the panel top side or panel surface 2 and the distance between the tongue bottom 13 from the panel bottom 3 can vary depending on the panel thickness.
- the upper side 12 of the tongue 11 has a flat surface 19, which is arranged horizontally in relation to the panel top.
- the length of the top of the tongue can be determined in the cross profile ( Figure 1A ) and longitudinal profile ( Figure 2A ) be the same, while the length of the lower tongue side in the transverse profile is greater than the length of the lower tongue side in the longitudinal profile.
- the lower side of the spring 11 has a bevel or bevel 17 at its edge at an angle between 45-55 °.

- the projection 14 has an inclination between 10 ° (transverse profile) and 44 ° (longitudinal profile) with respect to the flat, horizontal section of the underside 13 of the spring.
- the length and height of the projection 14 also vary depending on the design of the spring as a transverse profile or a longitudinal profile.
- the spring profile of the Figure 1A has a joining surface 16 on the side edge, which runs from the top 2 of the floor panel to the upper tongue side 12 and has a bevel or inclination from the upper side of the floor panel in the direction of the upper tongue side.
- the bevel of the joining surface 16 runs at an angle of 1 ° with respect to the perpendicular to the top of the floor panels.

- the groove 21 provided in the second side edge 20 of the floor panel 1 has a top side and a bottom side, the top side of the groove 21 being delimited by an upper lip 22 and the underside of the groove being delimited by a lower lip 23.
- the width or width of the groove formed by the upper lip 22 and the lower lip 23 corresponds to the thickness of the tongue 11, so that the tongue 11 can be inserted into the groove 21.
- the lower side of the upper lip 23 of the groove with surface 29, like the surface 19 of the upper side of the tongue, is arranged flat and horizontally so that the tongue and groove can engage or can be pushed into one another without resistance.
- Surface 19 of the upper side of the tongue and surface 29 of the lower side of the upper lip 23 form contact surfaces which are essentially parallel to the plane defined by the floor panel.
- the thickness of the upper lip 22 and the lower lip 23 differ, wherein the upper lip 22 can be thicker than the lower lip 23. Due to a smaller thickness of the lower lip 23, this serves as an elastically bendable projection.
- a recess 24 with a contact surface 25 is provided in the lower lip 23 of the groove, the recess 24 cooperating with the contact surface 25 complementarily to the tongue 11 with the contact surface 15.
- a saddle 27 is formed in the recess 24. The formation of the saddle 27 in the transverse profile ( Figure 1B ) and the saddle 47 longitudinal profile ( Figure 2B ) is differently pronounced, which is due to the technical profile geometry and the associated prestressing effect.
- the groove profiling of the Figure 1B has a joining surface 26 on the side edge which runs along the upper lip 22.
- the joining surface 26 is - like the joining surface 16 of the tongue - beveled, the beveling of the joining surface 26 here also running at an angle of 1 ° with respect to the perpendicular to the panel top.
- a ramp surface 28 is provided, which makes it easier for the short transverse sides to engage in one another.
- the corresponding ramp surface 48 in the longitudinal profile ( Figure 2B ), on the other hand, is less strongly developed and is rather intended as a rounding. This geometric difference is due to the different behavior of the transverse profile and the longitudinal profile when the profiles are angled in during laying.
- the ramp surface 28 enables easier placement of the transverse profiles. In addition, laying with hammer wood is guaranteed without damaging the profiles.
- this cavity or dust chamber between recess 44 and projection 34 is smaller.
- This is related to the selected spring mechanism of the groove profiles in the transverse profile and longitudinal profile, with the rebound in the transverse profile being greater than in the longitudinal profile.
- the transverse profile also has a higher profile spacing compared to the longitudinal profile (ie lower lip 23 of the transverse profile is longer than the lower lip 43 of the longitudinal profile. This allows the groove cheek of the transverse profile to rebound, which in combination with the ramp surface 28 and the cavity creates a lighter
- the slightly varying profile dimensions and geometry of the transverse profile and longitudinal profile are due in particular to the different behavior of the transverse profile and the longitudinal profile when the profiles are angled in during laying by different lever arms.
- the ones in the Figures 2A to 2C The ones in the Figures 2A to 2C
- the shown second embodiment of the tongue and groove profile is, as already mentioned, provided as a longitudinal profile in the longitudinal sides of the floor panel.
- the spring profiling of the Figure 2A essentially corresponds to the spring profiling of the Figure 1A , wherein the length of the lower spring side 13 in the transverse profile differs from the length of the lower spring side 33 in the longitudinal profile.
- the length of the lower spring side 13 in the transverse profile is longer than in the longitudinal profile of the Figure 2A .
- the geometry of the projection 14 in the transverse profile differs from the geometry of the projection 34 in the longitudinal profile.
- the projection 14 in the transverse profile is made weaker than the projection 34 in the longitudinal profile, ie the height of the projection 14 in the transverse profile is smaller than the height of the projection 34 in the longitudinal profile.
- This geometrical difference is also due to the different behavior of the transverse profile and the longitudinal profile when the profiles are angled in during laying by different lever arms.
- the groove profiling of the Figure 2B differs from the groove profiling of the Figure 1B especially in the angle of inclination of the beveled joining surface. So the joining surface 26 is the Figure 1B beveled by 1 °, while the joining surface 46 in the Figure 2B has a bevel of 2 °. The differences in the bevel of the joining surfaces of the groove profile in the transverse profile and in the longitudinal profile are due to the length of the transverse and longitudinal sides.
- the length of the lower lip 23 of the transverse profile also differs from the length of the lower lip 43 of the longitudinal profile, the lower lip 23 of the transverse profile being longer than the lower lip 43 of the longitudinal profile.
- the ones in the Figures 3A to 3B The third embodiment of the tongue and groove profile shown is provided in the transverse sides of a floor panel with a thickness of 12 mm as a transverse profile.
- the fourth embodiment of the tongue-and-groove profiling shown is in turn provided in the longitudinal sides of a floor panel with a thickness of 12 mm as a longitudinal profile.
- the tongue and groove profiles of the Figures 3A, 3B and 4A, 4B essentially correspond to the tongue and groove profiles of Figures 1A, 1B and 2A, 2B so that reference is made to the above statements.

Description
Die vorliegende Erfindung betrifft ein hartes Fußbodenpaneel zur schwimmenden Verlegung unter Ausbildung eines Fußbodenpaneelverbundes, insbesondere eines Laminatfußbodens.The present invention relates to a hard floor panel for floating installation with the formation of a floor panel composite, in particular a laminate floor.
Fußbodenpaneele mit Feder-Nut-Profilen an den Seitenkanten zur Verlegung zu Paneelverbunden, wie Laminatfußböden, sind weit verbreitet und herkömmlich bekannt. Die Feder-Nut-Profile ermöglichen eine einfache Verlegung von Fußbodenpaneelen zu Fußbodenbelägen. Solche Fußbodenbeläge können zum Beispiel aus Holzfaserplatten oder Kunststoffplatten bestehen. Meistens sind die Fußbodenpaneele mit einer Dekorschicht und einer abriebfesten Oberflächenschicht versehen.Floor panels with tongue and groove profiles on the side edges for laying to form panels, such as laminate floors, are widely used and conventionally known. The tongue and groove profiles make it easy to lay floor panels to floor coverings. Such floor coverings can consist of wood fiber panels or plastic panels, for example. Most of the time, the floor panels are provided with a decorative layer and an abrasion-resistant surface layer.
Die herkömmlich verwendeten Feder-Nut-Profile weisen jedoch den Nachteil auf, dass es zwischen den aneinander liegenden Paneelen zur Ausbildung von Spalten mit unterschiedlicher Größe kommt. Schmutz wie auch Feuchtigkeit können in diese Spalten eindringen und zu einer Expansion bzw. Quellung der Trägerplatte des Fußbodenpaneels, insbesondere im Falle der Verwendung von Holzwerkstoffplatten als Trägerplatten, führen. Die Expansion bzw. Quellung der Holzwerkstoffträgerplatte verursacht ein Anheben der Oberflächenschicht, so dass die Oberflächenschicht einem verstärkten Abrieb ausgesetzt ist.The tongue and groove profiles conventionally used, however, have the disadvantage that gaps of different sizes are formed between the panels lying against one another. Dirt as well as moisture can penetrate into these gaps and lead to expansion or swelling of the base plate of the floor panel, in particular if wood-based panels are used as base plates. The expansion or swelling of the wood-based panel causes the surface layer to rise, so that the surface layer is exposed to increased abrasion.
Unterschiedliche Vorrichtungen, um die Fußbodenpaneele während der Installation zusammenzufügen, können solche Spalten reduzieren bzw. verhindern. Die Verwendung von entsprechenden Vorrichtungen verkompliziert jedoch die Anwendung der Fußbodenpaneele und ist somit nicht von Vorteil.Different devices for joining the floor panels together during installation can reduce or prevent such gaps. However, the use of corresponding devices complicates the use of the floor panels and is therefore not advantageous.
Entsprechend wurden in der Vergangenheit verschiedene alternative Feder-Nut-Profile entwickelt, um die Spaltengröße zu verringern.Accordingly, various alternative tongue and groove profiles have been developed in the past to reduce the gap size.
So ist zum Beispiel aus der
Aber auch diese Ansätze bedingen einen Spalt auf der Oberseite der zusammengefügten Paneele, und hier insbesondere an den Kontaktpunkten der Fügeflächen der beiden sich gegenüberliegenden Seitenkanten von zwei zusammengefügten Fußbodenpaneelen, durch welchen Feuchtigkeit und Schmutz zwischen die Fußbodenpaneele eindringen kann.But these approaches also require a gap on the top of the assembled panels, and here in particular at the contact points of the joining surfaces of the two opposite side edges of two assembled floor panels, through which moisture and dirt can penetrate between the floor panels.
Es war demnach die Aufgabe der vorliegenden Erfindung, die aus dem Stand der Technik bekannten Feder-Nut-Profile derart weiter zu entwickeln, so dass eine Spaltbildung an den Fügeflächen der Fußbodenpaneele vermieden wird, umso das Eindringen von Feuchtigkeit und Schmutz und die damit einhergehenden Nachteile zu verhindern.It was therefore the object of the present invention to further develop the tongue and groove profiles known from the prior art in such a way that the formation of gaps on the joining surfaces of the floor panels is avoided, as is the penetration of moisture and dirt and the associated disadvantages to prevent.
Diese Aufgabe wird mit einem Fußbodenpaneel mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with a floor panel with the features of
Entsprechend wird ein Fußbodenpaneel, insbesondere mit einem Kern aus einer Holzwerkstoffplatte, einer Holzwerkstoff-Kunststoff-Platte oder einer Kunststoffplatte, mit einer Oberseite und einer Unterseite und mit Seitenkanten entlang der Paneelseiten (d.h. entlang der Längsseiten und Querseiten) zur schwimmenden Verlegung unter Ausbildung eines Fußbodenpaneelverbundes bereitgestellt,
wobei jeweils mindestens zwei Fußbodenpaneele zusammengefügt bzw. miteinander verbunden werden,
wobei die gegenüberliegenden Seitenkanten mit Feder-Nut-Profilierungen versehen sind,
wobei in einer ersten Seitenkante eine Feder und eine Fügefläche vorgesehen sind und in einer zweiten gegenüberliegenden Seitenkante eine Nut und eine Fügefläche vorgesehen sind,
wobei die Feder der ersten Seitenkante eine obere Seite und eine untere Seite aufweist;
wobei an der unteren Seite der Feder ein Vorsprung mit einer Kontaktfläche vorgesehen ist;
wobei die Fügefläche der ersten Seitenkante von der Oberseite des Fußbodenpaneels hin zur oberen Federseite verläuft und die Fügefläche abgeschrägt ausgebildet ist; wobei die Fügefläche der ersten Seitenkante von der Oberseite des Fußbodenpaneels nach innen weg von der Senkrechten weg von der Feder geneigt ist
so dass der Winkel zwischen Paneeloberseite und Fügefläche nicht länger rechtwinkling ist, sondern einen spitzen Winkel zwischen 85° und 89° bildet, wobei die Nut in der zweiten Seitenkante eine Oberseite und eine Unterseite aufweist,
wobei die Oberseite der Nut von einer oberen Lippe begrenzt wird und die Unterseite der Nut von einer unteren Lippe begrenzt wird;
wobei in der unteren Lippe der Nut eine Aussparung mit einer Kontaktfläche vorgesehen ist;
wobei die Fügefläche der zweiten Seitenkante von der Oberseite des Fußbodenpaneels entlang der oberen Lippe der Nut verläuft und die Fügefläche abgeschrägt ausgebildet ist; wobei die Fügefläche der zweiten Seitenkante von der Oberseite des Fußbodenpaneels nach innen weg von der Senkrechten hin zur Nut geneigt ist
so dass der Winkel zwischen Paneeloberseite und Fügefläche nicht länger rechtwinkling ist, sondern einen spitzen Winkel zwischen 85° und 89° bildet, wobei im zusammengefügten Zustand von mindestens zwei Fußbodenpaneelen der Vorsprung der Feder in die Aussparung der unteren Lippe der Nut eingreift, so dass die Kontaktflächen des Vorsprungs der Feder und der Aussparung der unteren Lippe der Nut eine Spannkraft aufeinander ausüben; und
wobei es bei Anlage der abgeschrägten Fügefläche der ersten Seitenkante der Feder-Profilierung und der abgeschrägten Fügefläche der zweiten Seitenkante der Nut-Profilierung im zusammengefügten Zustand von mindestens zwei Fußbodenpaneelen an den Kontaktpunkten zu einer Linienpressung entlang der abgeschrägten Fügeflächen der Seitenkanten der Feder-Profilierung und der Nut-Profilierung kommt.Accordingly, a floor panel, in particular with a core made of a wood-based panel, a wood-based plastic panel or a plastic panel, with an upper side and a lower side and with side edges along the panel sides (i.e. along the long sides and transverse sides) is used for floating installation with the formation of a floor panel composite provided,
whereby at least two floor panels are put together or connected to one another,
the opposite side edges are provided with tongue and groove profiles,
wherein a tongue and a joining surface are provided in a first side edge and a groove and a joining surface are provided in a second opposite side edge,
wherein the tongue of the first side edge has an upper side and a lower side;
wherein a projection with a contact surface is provided on the lower side of the spring;
wherein the joining surface of the first side edge runs from the top of the floor panel to the upper tongue side and the joining surface is beveled; wherein the joining surface of the first side edge is inclined from the top of the floor panel inwardly away from the perpendicular away from the tongue
so that the angle between the top of the panel and the joining surface is no longer right-angled, but forms an acute angle between 85 ° and 89 °, the groove in the second side edge having a top and a bottom,
wherein the top of the groove is bounded by an upper lip and the bottom of the groove is bounded by a lower lip;
wherein a recess with a contact surface is provided in the lower lip of the groove;
wherein the joining surface of the second side edge extends from the top of the floor panel along the upper lip of the groove and the joining surface is beveled; wherein the joining surface of the second side edge is inclined from the top of the floor panel inwardly away from the vertical towards the groove
so that the angle between the top of the panel and the joining surface is no longer right-angled, but forms an acute angle between 85 ° and 89 °, with the projection of the tongue engaging in the recess of the lower lip of the groove when at least two floor panels are joined together, so that the Contact surfaces of the projection of the tongue and the recess of the lower lip of the groove exert a tension force on one another; and
where, when the beveled joining surface of the first side edge of the tongue profile and the beveled joint surface of the second side edge of the groove profile are in contact with at least two floor panels at the contact points, there is a line pressure along the beveled joint surfaces of the side edges of the tongue profile and the Groove profiling is coming.
Durch die erfindungsgemäße Kombination von Spannkraft und Linienpressung ist es nunmehr möglich, die Bildung von Spalten zwischen anliegenden Fußbodenpaneelen zu vermeiden, und somit den Eintritt von Feuchtigkeit und Schmutz in den Fußbodenbelag zu reduzieren. Die Linienpressung ergibt sich dabei aus der Profilgeometrie und dem aufzubringenden Druck.Due to the combination of tension and line pressure according to the invention, it is now possible to avoid the formation of gaps between adjacent floor panels, and thus to reduce the entry of moisture and dirt into the floor covering. The line pressure results from the profile geometry and the pressure to be applied.
Feder und Nut weisen bevorzugt Formen auf, die zueinander komplementär sind. Der Vorsprung an der unteren Seite der Feder erstreckt sich entlang der unteren Lippe der Nut und greift in die Aussparung der unteren Lippe der Nut im gekoppelten Zustand von zwei Paneelen ein. Die Kontaktflächen des Vorsprungs der Feder und der Aussparung liegen aneinander an. Die Feder setzt im zusammengefügten Zustand der Fußbodenpaneele präzise gegen die obere Seite und die untere Seite der Nut an, wobei ein Druck P auf die obere Lippe der Nut ausgeübt wird. Dieser Druck wird nicht nur von der oberen Lippe aufgenommen, sondern von der kompletten Struktur, da der Druck durch die Feder und die untere Lippe übertragen werden kann. Durch den Pressdruck P wird die Spannkraft hervorgerufen, durch die die Paneele zusammengefügt und gehalten werden.The tongue and groove preferably have shapes that are complementary to one another. The protrusion on the lower side of the tongue extends along the lower lip of the groove and engages the recess of the lower lip of the groove when two panels are coupled. The contact surfaces of the projection of the spring and the recess lie against one another. In the assembled state of the floor panels, the tongue is precisely positioned against the upper side and the lower side of the groove, a pressure P being exerted on the upper lip of the groove. This pressure is not only absorbed by the upper lip, but by the entire structure, since the pressure can be transmitted through the spring and the lower lip. The clamping force by which the panels are joined and held is produced by the pressing pressure P.
Wie oben ausgeführt, kommt es bei Anlage der abgeschrägten Fügefläche der Feder-Profilkante und der abgeschrägten Fügefläche der oberen Lippe der Nut-Profilkante zu einer Linienpressung, wodurch ein Eindringen von Feuchtigkeit verhindert wird.As stated above, when the beveled joining surface of the tongue profile edge and the beveled joining surface of the upper lip of the groove profile edge come into contact with a line pressure, which prevents moisture penetration.
Unter Abschrägung der Fügeflächen bzw. Fügekanten ist im Sinne der vorliegenden Erfindung eine Anschrägung oder Neigung der Fügeflächen bzw. Fügekanten von der Oberseite des Paneels nach innen weg von der Senkrechten weg von der Feder bzw. hin zur Nut zu verstehen.In the context of the present invention, bevel of the joining surfaces or joining edges is to be understood as a bevel or inclination of the joining surfaces or joining edges from the top of the panel inwardly away from the vertical away from the tongue or towards the groove.
Üblicherweise bilden Paneeloberseite und die jeweilige Fügefläche der Seitenkanten einen rechten Winkel (90°) aus; d.h. Paneeloberseite und Fügefläche sind rechtwinklig zueinander angeordnet. Im vorliegenden Fall ist der Winkel zwischen Paneeloberseite und Fügefläche nicht länger rechtwinklig, sondern bildet einen (spitzen) Winkel zwischen 85° und 89°, bevorzugt zwischen 87° und 89°, besonders bevorzugt 88° und 89°.The top of the panel and the respective joining surface of the side edges usually form a right angle (90 °); i.e. the top of the panel and the joining surface are arranged at right angles to one another. In the present case, the angle between the top of the panel and the joining surface is no longer rectangular, but forms an (acute) angle between 85 ° and 89 °, preferably between 87 ° and 89 °, particularly preferably 88 ° and 89 °.
Mit anderen Worten, die Fügeflächen sind jeweils um einen Winkel zwischen 1 und 5°, bevorzugt zwischen 1 und 3°, besonders bevorzugt 2 und 3° weg von der Senkrechten (zur Paneeloberseite) geneigt.In other words, the joining surfaces are each inclined at an angle between 1 and 5 °, preferably between 1 and 3 °, particularly preferably 2 and 3 °, away from the vertical (to the top of the panel).
Entsprechend beträgt in einer Ausführungsform des vorliegenden Paneels die Abschrägung oder Neigung der Fügefläche der ersten Seitenkante der Feder-Profilierung von der Oberseite des Fußbodenpaneels weg von der oberen Federseite zwischen 1 und 5°, bevorzugt zwischen 1 und 3°, besonders bevorzugt zwischen 1 und 2°.Correspondingly, in one embodiment of the present panel, the bevel or inclination of the joining surface of the first side edge of the tongue profile from the top of the floor panel away from the upper tongue side is between 1 and 5 °, preferably between 1 and 3 °, particularly preferably between 1 and 2 °.
In einer anderen Ausführungsform des vorliegenden Paneels beträgt die Abschrägung bzw. Neigung der Fügefläche der zweiten Seitenkante der Nut-Profilierung von der Oberseite des Fußbodenpaneels entlang der oberen Lippe bis hin der Nut zwischen 1 und 5°, bevorzugt zwischen 1 und 3°, besonders bevorzugt zwischen 1 und 2°.In another embodiment of the present panel, the bevel or inclination of the joining surface of the second side edge of the groove profile from the top of the floor panel along the upper lip to the groove is between 1 and 5 °, preferably between 1 and 3 °, particularly preferred between 1 and 2 °.
In einer bevorzugten Ausführungsform weisen Abschrägung bzw. Neigung der Fügeflächen der Feder-Profilierung und der Nut-Profilierung jeweils die gleichen Winkel auf. So kann die Fügefläche der Feder-Profilierung um 1° abgeschrägt sein und die Fügefläche der Nut-Profilierung kann ebenfalls um 1° abgeschrägt sein.In a preferred embodiment, the bevel or inclination of the joining surfaces of the tongue profile and the groove profile each have the same angle. The joining surface of the tongue profile can be beveled by 1 ° and the joining surface of the groove profile can also be beveled by 1 °.
Es ist aber auch möglich, dass Abschrägung bzw. Neigung der Fügeflächen der Feder-Profilierung und der Nut-Profilierung jeweils unterschiedliche Winkel aufweisen. So kann die Fügefläche der Feder-Profilierung um 1° abgeschrägt sein und die Fügefläche der Nut-Profilierung kann um 2° abgeschrägt sein.However, it is also possible that the bevel or inclination of the joining surfaces of the tongue profile and the groove profile each have different angles. The joining surface of the tongue profile can be beveled by 1 ° and the joining surface of the groove profile can be beveled by 2 °.
Es ist auch möglich, dass in einer nicht zur beanspruchten Erfindung gehörenden Variante die Fügefläche der Feder-Profilierung keine Abschrägung bzw. Neigung aufweist (d.h. im rechten Winkel zur Oberseite des Fußbodenpaneels verlaufend) und zweite Fügefläche der Nut-Profilierung eine Abschrägung bzw. Neigung aufweist.It is also possible that, in a variant not belonging to the claimed invention, the joining surface of the tongue profile has no bevel or slope (ie running at right angles to the top of the floor panel) and the second joining surface of the groove profile has a bevel or slope .
Der umgekehrte Fall ist auch möglich, gehört jedoch ebenfalls nicht zur beanspruchten Erfindung. In solch einer Variante würde die erste Fügefläche der Feder-Profilierung eine Abschrägung aufweisen und die zweite Fügefläche der Nut-Profilierung keine Abschrägung (d.h. im rechten Winkel zur Oberseite des Fußbodenpaneels verlaufend) aufweisen.The reverse case is also possible, but also does not belong to the claimed invention. In such a variant, the first joining surface of the tongue profile would have a bevel and the second joint surface of the groove profile would have no bevel (i.e. running at right angles to the top of the floor panel).
Bei Anlage der abgeschrägten Fügefläche der Feder-Profilierung und der abgeschrägten Fügefläche der Nut-Profilierung im zusammengefügten Zustand von zwei Fußbodenpaneelen kommt es an dem Kontaktpunkt der Fügeflächen zu einer Linienpressung. Aufgrund der Abschrägung der Fügeflächen bildet sich ausgehend von dem (oberen) Kontaktpunkt als Scheitelpunkt ein Winkel zwischen den gegenüberliegenden Fügeflächen aus, dessen Größe von den Winkelgrößen der abgeschrägten Fügeflächen abhängig ist und zwischen 2 und 10°, bevorzugt zwischen 2 und 6°, bevorzugt zwischen 2 und 3° liegt. So kann der Winkel zwischen den gegenüberliegenden Fügeflächen bei einer Abschrägung der Fügefläche der Feder-Profilierung von 1° und einer Abschrägung der Fügefläche der Nut-Profilierung von 1° insgesamt 2° betragen. Im Falle einer Abschrägung der Fügefläche der Feder-Profilierung von 1° und einer Abschrägung der Fügefläche der Nut-Profilierung von 2° beträgt der Winkel zwischen den gegenüberliegenden Fügeflächen insgesamt 3°.When the beveled joining surface of the tongue profile and the beveled joining surface of the groove profile are placed in the joined state of two floor panels, there is a line pressure at the contact point of the joining surfaces. Due to the bevel of the joining surfaces, starting from the (upper) contact point as the apex, an angle forms between the opposite joining surfaces, the size of which depends on the angular sizes of the beveled joining surfaces and between 2 and 10 °, preferably between 2 and 6 °, preferably between 2 and 3 °. Thus, the angle between the opposing joining surfaces with a bevel of the joining surface of the tongue profile of 1 ° and a bevel of the joining surface of the groove profile of 1 ° can total 2 °. In the case of a bevel of the joining surface of the spring profile of 1 ° and a bevel of the joining surface of the groove profile of 2 °, the angle between the opposing joining surfaces is a total of 3 °.
Im Folgenden werden die Konstruktion der Feder-Profilierung und der Nut-Profilierung näher beschrieben.The construction of the tongue profile and the groove profile are described in more detail below.
Die in dem vorliegenden Fußbodenpaneel vorgesehenen Profilierungen mit Feder und Nut als Kopplungsteile zwischen zwei Paneelen sind bevorzugt einstückig ausgebildet.The profilings with tongue and groove provided in the present floor panel as coupling parts between two panels are preferably designed in one piece.
Wie oben angeführt, ist in einer ersten Seitenkante eine Feder mit einer oberen Seite und unteren Seite vorgesehen. Der Abstand der Federoberseite von der Oberseite des Paneels und der Federunterseite von der Unterseite des Paneels kann in Abhängigkeit von der Paneeldicke variieren.As stated above, a spring with an upper side and a lower side is provided in a first side edge. The distance between the top of the tongue from the top of the panel and the underside of the tongue from the underside of the panel can vary depending on the panel thickness.
Die Dicke der Feder ist bevorzugt gleich der Weite der Nut, so dass die obere Lippe der Nut durch die Feder gestützt wird, und die Feder wiederum durch die untere Lippe der Nut gestützt wird.The thickness of the tongue is preferably equal to the width of the groove so that the upper lip of the groove is supported by the tongue and the tongue is in turn supported by the lower lip of the groove.
Die obere Seite der Feder ist flach bzw. eben und horizontal in Bezug auf die Paneeloberseite ausgebildet. Die obere Seite der Nut (bzw. untere Seite der oberen Lippe der Nut) ist ebenfalls eben und horizontal angeordnet, so dass Feder und Nut ohne Widerstand ineinandergreifen können bzw. ineinander schiebbar sind. Oberseite der Feder und der Unterseite der oberen Lippe bilden Kontaktflächen, die im Wesentlichen parallel zu der von dem Fußbodenpaneel definierten Ebene verlaufen.The upper side of the tongue is flat or flat and horizontal in relation to the panel upper side. The upper side of the groove (or lower side of the upper lip of the groove) is also arranged flat and horizontally, so that the tongue and groove can engage or can be pushed into one another without resistance. The top of the tongue and the underside of the upper lip form contact surfaces which are essentially parallel to the plane defined by the floor panel.
In einer weiteren Ausführungsform des vorliegenden Fußbodenpaneels ist zwischen der Fügefläche der Feder-Profilierung und der Oberseite der Feder eine Aussparung vorgesehen.In a further embodiment of the present floor panel, a recess is provided between the joining surface of the tongue profile and the top of the tongue.
Es ist auch vorgesehen, dass die untere Seite der Feder an ihrer Kante eine Schräge aufweist. Diese Abschrägung kann auch als eine Fase mit einem Winkel zwischen 45-55° beschrieben werden.It is also provided that the lower side of the spring has a bevel at its edge. This bevel can also be described as a chamfer with an angle between 45-55 °.
Wie oben bereits beschrieben, erstreckt sich der an der unteren Seite der Feder vorgesehene Vorsprung entlang der unteren Lippe der Nut. Der Vorsprung greift in die Aussparung der unteren Lippe der Nut im gekoppelten Zustand von zwei Paneelen ein. Der Winkel der Kontaktflächen des Vorsprungs der Feder und der Aussparung der unteren Lippe beträgt in Bezug auf die horizontale Ebene zwischen 30 und 70°. Dieser Winkel ist ideal, um ein optimales Zusammenpressen der Fußbodenpaneele zu erreichen und gleichzeitig ein einfaches Eingreifen und Zusammenbauen der Fußbodenpaneele zu ermöglichen.As already described above, the projection provided on the lower side of the tongue extends along the lower lip of the groove. The projection engages in the recess of the lower lip of the groove in the coupled state of two panels. The angle of the contact surfaces of the protrusion of the spring and the recess of the lower lip is in Relation to the horizontal plane between 30 and 70 °. This angle is ideal to achieve an optimal compression of the floor panels and at the same time to allow easy engagement and assembly of the floor panels.
Im zusammengefügten bzw. gekoppelten Zustand von Feder und Nut kann sich zwischen Vorsprung der unteren Federseite und Aussparung in der unteren Lippe der Nut ein zusätzlicher Raum ausbilden, der z.B. als Staubkammer fungiert. Die Größe der Staubkammer kann z.B. zwischen den Profilen in den Paneellängsseiten (Längsprofil) und Paneelquerseiten (Querprofil) variieren.When the tongue and groove are joined or coupled, an additional space can form between the projection of the lower tongue side and the recess in the lower lip of the groove, which e.g. functions as a dust chamber. The size of the dust chamber can, for example, vary between the profiles in the panel longitudinal sides (longitudinal profile) and panel transverse sides (transverse profile).
Es ist auch vorgesehen, dass sich die untere Lippe der Nut über die obere Lippe der Nut hinaus erstreckt. In diesem Fall befindet sich die Aussparung in der unteren Lippe der Nut in dem Abschnitt der unteren Lippe, der sich über die obere Lippe der Nut hinaus erstreckt.It is also contemplated that the lower lip of the groove extends beyond the upper lip of the groove. In this case, the recess in the lower lip of the groove is in the portion of the lower lip that extends beyond the upper lip of the groove.
In einer Ausführungsform des vorliegenden Fußbodenpaneels ist in der Aussparung der unteren Lippe der Nut mindestens ein Sattel vorgesehen. Dieser Sattel kann im Querprofil und Längsprofil unterschiedlich stark ausgeprägt sein.In one embodiment of the present floor panel, at least one saddle is provided in the recess of the lower lip of the groove. This saddle can be differently pronounced in the transverse profile and longitudinal profile.
Die Dicke der oberen Lippe der Nut kann größer oder gleich sein als die Dicke der unteren Lippe. Im Falle von unterschiedlichen Dicken von oberer und unterer Lippe ist die Zentrallinie durch die Feder und die Nut unterhalb der Mittellinie des Paneels angeordnet. In dieser Anordnung wird die untere Lippe der Nut beim Zusammenfügen von zwei Fußbodenpaneelen gebogen, so dass die Oberseite des Fußbodenpaneels keinen Veränderungen oder Umformungen ausgesetzt ist.The thickness of the upper lip of the groove can be greater than or equal to the thickness of the lower lip. In the case of different thicknesses of the upper and lower lip, the central line through the tongue and the groove is arranged below the center line of the panel. In this arrangement, the lower lip of the groove is bent when joining two floor panels so that the top of the floor panel is not subject to any changes or deformations.
Auch weisen obere und untere Lippen abgerundete Kanten auf, wodurch das Zusammenfügen der Paneele vereinfacht wird. So kann die Fügefläche der oberen Lippe eine abgerundete Kante oder Fase aufweisen. Die Fase ist am Kontaktpunkt von obere Lippe der Nut mit der Oberseite der Feder vorgesehen und ermöglicht ein einfaches Zusammenfügen der Fußbodenpaneele.The upper and lower lips also have rounded edges, which simplifies the assembly of the panels. For example, the joining surface of the upper lip can have a rounded edge or bevel. The bevel is provided at the point of contact between the upper lip of the groove and the top of the tongue and enables the floor panels to be easily assembled.
In einer anderen Ausführungsform ist am freien Ende der unteren Lippe der Nut ebenfalls eine Neigungsfläche bzw. Fase (oder auch Rampenfläche) vorgesehen, wodurch ein einfaches Schieben der Feder-Nut-Profile ineinander ermöglicht wird.In another embodiment, an inclined surface or bevel (or ramp surface) is also provided at the free end of the lower lip of the groove, which enables the tongue-and-groove profiles to be easily pushed into one another.
Am Übergang von Feder- und Nut-Profilierung zur Unterseite des Paneels ist eine Fase bzw. Abschrägung über eine Länge von 0,6 mm mit einem Winkel zwischen 20 und 30°, bevorzugt 25° vorgesehen. Die Fase ist insbesondere in einem auf der Paneelunterseite angeordneten Gegenzug vorgesehen und ermöglicht ein besseres Verlegen ohne Splitterbildung.At the transition from tongue and groove profiling to the underside of the panel, a bevel or bevel is provided over a length of 0.6 mm at an angle between 20 and 30 °, preferably 25 °. The bevel is in particular provided in a counter-pull arranged on the underside of the panel and enables better laying without splinters.
In weiteren Ausführungsformen des vorliegenden Fußbodenpaneels ist vorgesehen, dass die Feder-Nut-Profilierungen eine der folgenden Eigenschaften oder einer Kombination davon aufweisen: Rundungen an den Ecken (bzw. Kanten) der Feder-Nut-Profilierungen; Staubkammern zwischen allen Seiten der ineinandergefügten Fußbodenpaneele; insbesondere die oben erwähnte Staubkammer zwischen Aussparung der unteren Lippe der Nut und dem Vorsprung der Feder;In further embodiments of the present floor panel it is provided that the tongue and groove profiles have one of the following properties or a combination thereof: roundings at the corners (or edges) of the tongue and groove profiles; Dust chambers between all sides of the nested floor panels; in particular the above-mentioned dust chamber between the recess of the lower lip of the groove and the projection of the tongue;
Die Feder-Nut-Profilierungen ermöglichen ein Eingreifen von zwei Fußbodenpaneelen ineinander unter Aufbringen einer Drehbewegung bzw. Schwenkbewegung ("Angle-Angle"). Hierbei wird zunächst ein erstes Fußbodenpaneel schräg an einem horizontal angeordneten zweiten Fußbodenpaneel angesetzt gefolgt von einem Schwenken des ersten Fußbodenpaneels in Richtung der Verlegeebene, so dass die zusammengefügten Fußbodenpaneele in der Verlegeebene liegen. Damit die zwei Fußbodenpaneele ineinander mit einer Drehbewegung eingreifen können sind die Kanten bzw. Krümmungen bevorzugt abgerundet bzw. kreisförmig.The tongue and groove profiles enable two floor panels to intervene by applying a rotary movement or a pivoting movement ("Angle-Angle"). Here, a first floor panel is first placed at an angle on a horizontally arranged second floor panel, followed by pivoting the first floor panel in the direction of the laying plane, so that the assembled floor panels are in the laying plane. So that the two floor panels can engage one another with a rotary movement, the edges or curvatures are preferably rounded or circular.
Das vorliegende Fußbodenpaneel weist bevorzugt eine rechteckige Form auf, wobei an den längsverlaufenden Seitenkanten und an den querverlaufenden Seitenkanten jeweils die Feder-Nut-Profilierungen vorgesehen sind.The present floor panel preferably has a rectangular shape, the tongue and groove profiles being provided on the longitudinal side edges and on the transverse side edges.
Das für Verbindung der Paneele entlang der längsverlaufenden Seitenkanten verwendete Längsprofil kann die gleiche oder eine unterschiedliche Feder-Nut-Profilierung als das für die Verbindung der Paneele entlang der querverlaufenden Seitenkanten verwendete Querprofil aufweisen.The longitudinal profile used for connecting the panels along the longitudinal side edges can have the same or a different tongue and groove profile than the transverse profile used for connecting the panels along the transverse side edges.
Wesentliche Unterschiede zwischen Längsprofil und Querprofil betreffen die Ausbildung eines Sattels in der Aussparung der unteren Lippe, wodurch auch ein größerer Raum bzw. Kammer zwischen Federvorsprung und Nutaussparung im zusammengefügten Zustand der Fußbodenpaneele beding ist. Auch weist im Falle des Querprofils die untere Lippe der Nut am Nutende eine Rampenfläche auf, die im Längsprofil nicht vorgesehen ist.Significant differences between the longitudinal profile and the transverse profile relate to the formation of a saddle in the recess of the lower lip, which also requires a larger space or chamber between the spring projection and the groove recess when the floor panels are assembled. In the case of the transverse profile, the lower lip of the groove at the end of the groove also has a ramp surface which is not provided in the longitudinal profile.
Wie oben angeführt weisen die vorliegende Paneele einen Kern aus einer Holzwerkstoffplatte, bevorzugt einer HDF- oder MDF-Platte, aus einem Holzwerkstoff-Kunststoff-Platte, bevorzugt einer WPC-Platte, oder aus einer Kunststoffträgerplatte, bevorzugt PVC-Trägerplatte, auf. Im Falle der Verwendung von Kunststoff kann der der Kern wenigstens einen Füllstoff in einer Menge von bis zu 70% des Gesamtgewichts des Kerns der Trägerplatte aufweisen, wobei bevorzugt Calciumkarbonat oder Materialien mit vergleichbaren Eigenschaften verwendet werden.As stated above, the present panels have a core made of a wood-based board, preferably an HDF or MDF board, a wood-based plastic board, preferably a WPC board, or a plastic carrier board, preferably a PVC carrier board. If plastic is used, the core can have at least one filler in an amount of up to 70% of the total weight of the core of the carrier plate, calcium carbonate or materials with comparable properties being preferably used.
Die Dicke der Paneele kann zwischen 4 und 16 mm, bevorzugt zwischen 4,5 und 12 mm. Bevorzugte Paneeldicken sind 4,5 mm und 12 mm.The thickness of the panels can be between 4 and 16 mm, preferably between 4.5 and 12 mm. Preferred panel thicknesses are 4.5 mm and 12 mm.
Wie oben angeführt, werden die vorliegenden Fußbodenpaneele zum schwimmenden Verlegen von Fußbodenpaneelen verwendet. Ein entsprechendes Verlegeverfahren umfasst dabei die folgenden Schritte:
- Verlegen eines ersten Fußbodenpaneels, und
- Anfügen eines zweiten Fußbodenpaneels an das erste Fußbodenpaneel, wobei die Feder des zweiten Fußbodenpaneels in die Nut des ersten Fußbodenpaneels eingefügt wird, wobei die untere Lippe der Nut-Profilierung in dem zusammengefügten Zustand nach außen gebogen ist, so das die untere Lippe eine Kraft bereitstellt durch welche die Paneele permanent zueinander gezwungen werden.
- Laying a first floor panel, and
- Attaching a second floor panel to the first floor panel, the tongue of the second floor panel being inserted into the groove of the first floor panel, the lower lip of the groove profile being bent outwards in the assembled state, so that the lower lip provides a force through which the panels are permanently forced to one another.
Die durch das Zusammenwirken von Feder und Nut hervorgerufene Vorspannung wird optimal auf die obere Seite des Fußbodenpaneels übertragen, wobei in der Eingriffsrichtung die Fügeflächen der Nut- und Feder-Profilierungen derart aneinander gepresst werden, so dass es an dem Kontaktpunkt der Fügeflächen zu einer Linienpressung unter Ausbildung eines Winkels zwischen den Fügeflächen kommt.The pretension caused by the interaction of tongue and groove is optimally transferred to the upper side of the floor panel, with the joining surfaces of the tongue and groove profiles being pressed against one another in the engagement direction so that there is a line pressure at the contact point of the joining surfaces Formation of an angle between the joining surfaces comes.

Zudem unterscheidet sich die Geometrie des Vorsprungs 14 im Querprofil von der Geometrie des Vorsprungs 34 im Längsprofil. So ist der Vorsprung 14 im Querprofil schwächer ausgebildet als der Vorsprung 34 im Längsprofil, d.h. die Höhe des Vorsprungs 14 Querprofil ist kleiner als die Höhe des Vorsprungs 34 im Längsprofil. Auch dieser geometrische Unterschied ist durch das unterschiedliche Verhalten von Querprofil und Längsprofil beim Einwinkeln der Profile während des Verlegens durch unterschiedliche Hebelarme bedingt.In addition, the geometry of the
