Definitions
- the present invention relates to a panel for cladding, in particular a floor panel for a floor covering.
- Such a panel therefore always has a lower coupling element and an upper coupling element.
- an upper coupling element becomes one
- the panel to be assembled is pressed onto a lower coupling element of a panel that has already been assembled and lying on the ground.
- a wedge-shaped projection of the upper coupling element is pressed onto a counter surface of the lower coupling element that runs obliquely to the ground.
- the lower coupling element is spread open in the area of the locking receptacle by the penetrating locking element of the upper coupling element.
- the upper coupling element is spread open in the area of the locking receptacle by the penetrating locking element of the lower coupling element.
- the spreading of the upper and lower coupling elements leads to high material loads during assembly and thus regularly to material failure, especially in thermoplastic panels containing styrene block copolymer.
- US 10,000,935 B2 relates to a vertical connection system for substrates.
- the system is formed with interconnections that engage by relative movement in a direction perpendicular to the major surfaces of the substrate.
- the joints are configured to allow relative rotation of up to 3 degrees, ie, clockwise or counterclockwise, while maintaining joint engagement.
- the joints are further configured to form two locking levels, one on each of the innermost and outermost sides of the joint. Engagement around the locking planes is provided by transversely outwardly extending surfaces.
- the surfaces tower over the surfaces. At least one surface in each pair of engagement surfaces is smoothly curved.
- the joints may further be arranged to provide a third locking plane parallel to and between the locking planes. The joints are released by a combination of downward rotation of one joint relative to the other and then application of a downward force.
- flooring with the joint system can be installed on substrates that have undulations larger than current world industry standards. Additionally, replacing damaged substrates is possible by vertically lifting damaged substrates without having to pull up excess flooring from the nearest wall to the damaged substrates.
- EP 3 543 427 A1 relates to a panel with a top, a bottom, and side areas that are formed as outer edge areas.
- Each of the edge regions has an end face with a first profile or a second profile in the thickness direction of the panel.
- the first profile is formed as a tongue-and-groove profile or double tongue-and-groove profile with at least one first horizontal locking projection with a first stop edge over the entire length of its edge region.
- the second profile is formed as a tongue-and-groove profile or double tongue-and-groove profile corresponding to the first profile, with at least one second horizontal locking projection with a second stop edge over the entire length of its edge region.
- the horizontal locking projection associated with its profile only begins at a predetermined distance from one of the corners that the outer edge region forms with an abutting outer edge region.
- EP 3 581 732 A1 relates to a panel comprising a panel top, a panel bottom, a panel core and complementary locking means which are provided in pairs on opposite panel edges, at least one pair of locking means being provided with complementary hook profiles, namely a receiving hook and, opposite this, a locking hook, with the proviso that the receiving hook has a hook edge arranged away from the fuselage and a receiving recess arranged closer to the fuselage, the receiving recess being open to the top of the panel and the locking hook being provided with a locking recess arranged closer to the fuselage and open to the underside of the panel and having a locking shoulder arranged away from the fuselage which is inserted in the vertical joining direction into the receiving recess of the

- DE 20 2019 101807 U1 relates to a panel with a panel core, a panel surface, a panel underside and with at least one pair of edges of opposing complementary panel edges, which are provided with complementary locking means, the complementary locking means being designed in such a way that when two of these panels are joined together, they are located below a visible joint by means of the assembled complementary locking means, a locking effect of the panel edges can be achieved both in a direction perpendicular to the panel surface, and a locking effect against moving the panels apart, namely within the panel plane away from one another, can be achieved in a direction perpendicular to the locked panel edges, with the proviso that the Panel edges provided with the complementary locking means have an upper part area and a lower part area based on the thickness of the panel, the complementary locking means being arranged and designed in the lower part area of the panel edges, the upper part area of the panel edges being used for the design of the upper joint area including the visible one Part of the joint is provided and for this purpose the upper portion on each panel edge of the pair of edges has
- a material thickness of the lower coupling element between the lower surface of the panel and the locking receptacle is less than 100 percent of a material thickness of the upper coupling element between the panel surface and the locking receptacle.
- One idea of the present invention is that when two panels are joined together, coupling elements are spread out in a less stressful manner than previously known panels by means of an adapted dimensioning and thus tend to material failure or breakage with a reduced risk. It has been found that the assembly loads on the lower coupling element can fundamentally be better balanced than the assembly loads on the upper coupling element. One reason for this is that the lower coupling element rests on a surface during assembly of the upper coupling element. The forces acting on the lower coupling element can therefore be directly and evenly counteracted by the ground and less damaging to individual components of the lower coupling element. In contrast, we have on the upper one Coupling element forces acting during the joining of two panels do not have such an opportunity for force distribution, so that the upper coupling element is generally more prone to material failure.
- the lower coupling element has the lowest material thickness between the bottom surface of the panel and the locking receptacle.
- the upper coupling element has the lowest material thickness between the panel surface and the locking receptacle.
- material thickness means a minimum or maximum material thickness in this respective area. If the wording material thickness is used, this affects this definition or arrangement.
- the invention proposes that the material thickness of the upper coupling element is therefore greater than the material thickness of the lower coupling element.
- the information on the dimensioning of the panel is given with reference to a longitudinal section of the panel along its main axis of extension.
- each feature leads to a reduced risk of material failure of the lower and/or upper coupling element. It is essential that the material thickness of the upper coupling element is greater than the material thickness of the lower coupling element.
- the further dimensions of the subclaims are each advantageous, but not limiting or not absolutely necessary.
- the material thickness of the lower coupling element between the lower surface of the panel and the locking receptacle is at least 62 percent, preferably at least 67 percent and particularly preferably at least 72 percent, of the material thickness of the upper coupling element between the panel surface and the locking receptacle . It has been found that a lower coupling element dimensioned in this way increases the tendency for its material to fail is particularly advantageously reduced, with this improving with each stage, since there is increasing material in the lower coupling element for a force flow distribution that is gentle on components.
- the material thickness of the lower coupling element between the lower surface of the panel and the locking receptacle is at most 82 percent, at most 77 percent and particularly preferably at most 72 percent of the material thickness of the upper coupling element between the panel surface and the locking receptacle.
- the material thickness of the upper coupling element between the panel surface and the locking receptacle is at least 34 percent, preferably at least 39 percent, particularly preferably at least 44 percent, of the total thickness of the panel. It has been found that an upper coupling element dimensioned in this way reduces its tendency to material failure in a particularly advantageous manner, with this improving with each stage since there is increasing material in the upper coupling element for a force flow distribution that is gentle on components.
- the material thickness of the upper coupling element between the panel surface and the locking receptacle is at most 54 percent, preferably at most 49 percent, particularly preferably at most 44 percent, of the total thickness of the panel. This sets a preferred maximum rigidity of the upper coupling element, so that it is advantageously flexible or resilient for connecting two panels and no components break out of the lower coupling element.
- the material thickness of the lower coupling element between the bottom surface of the panel and the locking receptacle is at least 24 percent, preferably at least 29 percent, particularly preferably at least 34 percent, of the total thickness of the panel. These values have proven to be the preferred material thickness in order to further reduce the risk of undesirable material failure of the lower coupling element. This is made possible by an advantageous minimum force flow distribution volume.
- the material thickness of the lower coupling element between the bottom surface of the panel and the locking receptacle is at most 44 percent, preferably at most 39 percent, particularly preferably at most 34 percent, of the total thickness of the panel. It has been found that such a material thickness of the lower coupling element within these areas advantageously adjusts the rigidity of the lower coupling element in such a way that both the lower and the upper coupling element better withstand material failure.
- a radius of the arc shape of the locking element surface and/or a radius of the arc shape of the lock receiving surface is between 85 percent and 95 percent inclusive of the total thickness of the panel; and preferably approximately 90 percent of the total thickness of the panel. It has been found that within these values the most advantageous and even distribution of forces occurs. Due to the resulting flat arch shape, the coupling elements are advantageously protected against static friction and thus against the risk of breakage.
- a tangent to the center of the arcuate shape of the locking element surface and/or a tangent to the center of the arcuate shape of the locking receiving surface relative to the panel surface and the panel bottom surface has a respective arc angle of less than 45 degrees, preferably less than 35 degrees, particularly preferably less than 25 degrees includes or includes.
- the counter surface encloses a respective counter surface angle of less than 45 degrees, preferably less than 35 degrees, particularly preferably less than 25 degrees, relative to the panel surface and the bottom surface of the panel. This means that as many vertical forces as possible can be absorbed horizontally, evenly distributed, by the counter surface of the lower coupling element. At the same time there is sufficient inclination to form the first locking system. This protects components and protects the panel.
- an edge of the locking element facing a projection of the locking receptacle is designed as a curve. This reduces the risk of the locking element of the lower coupling element tilting with the locking element of the upper coupling element during the assembly of two panels.
- the locking element has a locking projection and the locking receptacle has a locking abutment, which form the second locking system in the coupled state of two panels.
- the locking element has a locking projection and the locking receptacle has a locking abutment, which form the third locking system in the coupled state of two panels.
- Such a configuration allows a reliable, form-fitting third locking system, whereby the interaction of the locking projection and the locking abutment means that the panel is not subjected to any load that could damage components.
- the panel has at least partially, preferably completely, thermoplastic styrene block copolymers, TPS, as the base material. It has been found that TPS-containing panels are particularly suitable for the stressed dimensions of the coupling elements. The same applies to materials that have similar properties to TPS or that only partially have TPS.
- Figure 1 shows a schematic longitudinal section view of two interconnected panels 10a, 10b according to the prior art.
- the representation is to be understood purely schematically and is not true to scale due to the arbitrary representation.
- a material thickness UM of the lower coupling element 18 between the panel lower surface 14 and the locking receptacle 26 is less than 100 percent of a material thickness OM of the upper coupling element 16 between the panel surface 12 and the locking receptacle 28.
- the upper coupling element 16 and the lower coupling element 18 are represented by two different panels 10a, 10b that are connected to one another.

In the embodiment of the invention according to Figure 2 As an example and independent of other features of this exemplary embodiment, this is 34 percent.
- a radius R of the arcuate shape of the locking element surface 32 and / or a radius of the arcuate shape of the locking receiving surface 34 is between 85 percent and 95 percent inclusive of the total thickness G of the panel 10a, 10b. In the embodiment of the invention according to Figure 2 By way of example and independently of other features of this exemplary embodiment, this is approximately 90 percent of the total thickness G of the panel 10a, 10b.

Description
Die vorliegende Erfindung betrifft ein Paneel für eine Verkleidung, insbesondere ein Fußbodenpaneel für einen Fußbodenbelag.The present invention relates to a panel for cladding, in particular a floor panel for a floor covering.
Bislang bekannt ist ein Paneel für eine Verkleidung, insbesondere ein Fußbodenpaneel für einen Fußbodenbelag, aufweisend
- eine Paneeloberfläche und eine hierzu parallele Paneelunterfläche, die mit einer Gesamtstärke voneinander beabstandet sind;
- ein oberes Koppelelement und ein unteres Koppelelement, wobei zwei solche Paneele mittels einer Abwärtsbewegung des oberen Koppelelements des ersten Paneels in Bezug auf das untere Koppelelement des zweiten Paneels aneinander koppelbar ausgebildet sind; wobei
- das obere Koppelelement an seinem distalen Ende einen keilförmigen Vorsprung und das untere Koppelelement eine Gegenfläche aufweisen, die im gekoppelten Zustand zweier Paneele ein erstes Verriegelungssystem bilden;
- das obere Koppelelement ein sich dem keilförmigen Vorsprung anschließendes Rastelement und das untere Koppelelement eine sich der Gegenfläche anschließende Rastaufnahme aufweisen, die im gekoppelten Zustand zweier Paneele ein zweites Verriegelungssystem bilden;
- das obere Koppelelement eine sich dem Rastelement anschließende Verriegelungsaufnahme und das untere Koppelelement an seinem distalen Ende ein sich der Rastaufnahme anschließendes Verriegelungselement aufweisen, die im gekoppelten Zustand zweier Paneele ein drittes Verriegelungssystem bilden.
- a panel surface and a panel bottom surface parallel thereto, which are spaced apart from one another by a total thickness;
- an upper coupling element and a lower coupling element, two such panels being designed to be coupled to one another by means of a downward movement of the upper coupling element of the first panel with respect to the lower coupling element of the second panel; where
- the upper coupling element has a wedge-shaped projection at its distal end and the lower coupling element has a counter surface, which form a first locking system when two panels are coupled;
- the upper coupling element has a latching element adjoining the wedge-shaped projection and the lower coupling element has a latching receptacle adjoining the counter surface, which form a second locking system in the coupled state of two panels;
- the upper coupling element has a locking receptacle adjoining the latching element and the lower coupling element has a locking element adjoining the latching receptacle at its distal end, which form a third locking system in the coupled state of two panels.
Ein solches Paneel hat somit stets ein unteres Koppelelement und ein oberes Koppelelement. Bei der Montage von Paneelen wird ein oberes Koppelement eines zu montierenden Paneels auf ein unteres Koppelelement eines bereits montierten und auf dem Untergrund liegenden Paneels aufgedrückt. Um das erste Verriegelungssystem zu bilden, wird ein keilförmiger Vorsprung des oberen Koppelelements auf eine zum Untergrund schräg verlaufende Gegenfläche des unteren Koppelelements gepresst. Um das zweite Verriegelungssystem zu bilden, wird das untere Koppelelement im Bereich der Rastaufnahme durch das eindringende Rastelement des oberen Koppelelements aufgespreizt. Um das dritte Verriegelungssystem zu bilden, wird das obere Koppelelement im Bereich der Verriegelungsaufnahme durch das eindringende Verriegelungselement des unteren Koppelelements aufgespreizt. Das Aufspreizen des oberen und des unteren Koppelelements führt zu hohen Materialbelastungen während der Montage und somit regelmäßig zu Materialversagen, insbesondere bei thermoplastischen Styrol-Blockcopolymer-aufweisenden Paneelen.Such a panel therefore always has a lower coupling element and an upper coupling element. When assembling panels, an upper coupling element becomes one The panel to be assembled is pressed onto a lower coupling element of a panel that has already been assembled and lying on the ground. In order to form the first locking system, a wedge-shaped projection of the upper coupling element is pressed onto a counter surface of the lower coupling element that runs obliquely to the ground. In order to form the second locking system, the lower coupling element is spread open in the area of the locking receptacle by the penetrating locking element of the upper coupling element. In order to form the third locking system, the upper coupling element is spread open in the area of the locking receptacle by the penetrating locking element of the lower coupling element. The spreading of the upper and lower coupling elements leads to high material loads during assembly and thus regularly to material failure, especially in thermoplastic panels containing styrene block copolymer.
Aufgrund dieser Eigenschaften kann ein Bodenbelag mit dem Fugensystem auf Untergründen verlegt werden, die Wellen aufweisen, die größer sind als die derzeitigen Weltindustriestandards. Zusätzlich ist das Ersetzen beschädigter Substrate durch vertikales Anheben beschädigter Substrate möglich, ohne dass überschüssiger Bodenbelag von der nächsten Wand zu den beschädigten Substraten hochgezogen werden muss.Due to these properties, flooring with the joint system can be installed on substrates that have undulations larger than current world industry standards. Additionally, replacing damaged substrates is possible by vertically lifting damaged substrates without having to pull up excess flooring from the nearest wall to the damaged substrates.

Nachfolgend werden Aspekte des beanspruchten Erfindungsgegenstandes erläutert und bevorzugte modifizierte Ausführungsformen der Erfindung beschrieben. Erläuterungen, insbesondere zu Vorteilen und Definitionen von Merkmalen, sind dem Grunde nach beschreibende und bevorzugte, jedoch nicht limitierende Beispiele. Sofern eine Erläuterung limitierend ist, wird dies ausdrücklich erwähnt.Aspects of the claimed subject matter of the invention are explained below and preferred modified embodiments of the invention are described. Explanations, especially regarding advantages and definitions of features, are essentially descriptive and preferred, but not limiting, examples. If an explanation is limiting, this will be expressly mentioned.
Ein Gedanke der vorliegenden Erfindung ist es also, dass Koppelelemente beim Zusammenfügen zweier Paneele durch eine angepasste Dimensionierung gegenüber vorbekannten Paneelen weniger belastend aufgespreizt werden und somit mit reduziertem Risiko zum Materialversagen beziehungsweise Bruch neigen. Dabei hat sich herausgestellt, dass die Montagebelastungen des unteren Koppelelements grundsätzlich besser ausgeglichen werden können als die Montagebelastungen des oberen Koppelelements. Dies ist unter anderem damit zu begründen, dass das untere Koppelelement während der Montage des oberen Koppelelements auf einem Untergrund aufliegt. Die auf das untere Koppelelement wirkenden Kräfte können somit unmittelbar und gleichmäßig vom Untergrund widergelagert werden und weniger schädigend auf einzelne Komponenten des unteren Koppelelements. Demgegenüber haben auf das obere Koppelelement wirkende Kräfte während des Fügens zweier Paneele keine solche Möglichkeit zur Kraftverteilung, sodass das obere Koppelelement grundsätzlich eher zum Materialversagen neigt. Ein solches Materialversagen beziehungsweise ein Bruch geschieht üblicherweise in Bereichen mit hoher Belastung und möglichst geringer Materialstärke. Das untere Koppelelement weist die geringste Materialstärke zwischen der Paneelunterfläche und der Rastaufnahme auf. Das obere Koppelelement weist die geringste Materialstärke zwischen der Paneeloberfläche und der Verriegelungsaufnahme auf. Als Materialstärke ist im Folgenden eine Mindest- beziehungsweise Höchstmaterialstärke in diesem jeweiligen Bereich gemeint. Sofern die Formulierung Materialstärke verwendet wird, betrifft dies diese Definition beziehungsweise Anordnung.One idea of the present invention is that when two panels are joined together, coupling elements are spread out in a less stressful manner than previously known panels by means of an adapted dimensioning and thus tend to material failure or breakage with a reduced risk. It has been found that the assembly loads on the lower coupling element can fundamentally be better balanced than the assembly loads on the upper coupling element. One reason for this is that the lower coupling element rests on a surface during assembly of the upper coupling element. The forces acting on the lower coupling element can therefore be directly and evenly counteracted by the ground and less damaging to individual components of the lower coupling element. In contrast, we have on the upper one Coupling element forces acting during the joining of two panels do not have such an opportunity for force distribution, so that the upper coupling element is generally more prone to material failure. Such a material failure or fracture usually occurs in areas with high loads and the lowest possible material thickness. The lower coupling element has the lowest material thickness between the bottom surface of the panel and the locking receptacle. The upper coupling element has the lowest material thickness between the panel surface and the locking receptacle. In the following, material thickness means a minimum or maximum material thickness in this respective area. If the wording material thickness is used, this affects this definition or arrangement.
Die Erfindung schlägt als Verbesserung eines Paneels vor, dass die Materialstärke des oberen Koppelelements somit größer ist als die Materialstärke des unteren Koppelelements.As an improvement to a panel, the invention proposes that the material thickness of the upper coupling element is therefore greater than the material thickness of the lower coupling element.
Grundsätzlich werden die Angaben zur Dimensionierung des Paneels mit Bezug auf einen Längsschnitt des Paneels entlang seiner Haupterstreckungsachse gemacht.Basically, the information on the dimensioning of the panel is given with reference to a longitudinal section of the panel along its main axis of extension.
Weiterhin ist für sämtliche folgende Dimensionierungen zu berücksichtigen, dass jedes Merkmal zu einem reduzierten Risiko eines Materialversagens des unteren und/oder oberen Koppelelements führt. Dabei ist wesentlich, dass das die Materialstärke des oberen Koppelelements größer ist als die Materialstärke des unteren Koppelelements. Die weiteren Dimensionierungen der Unteransprüche sind jeweils vorteilhaft, jedoch nicht limitierend beziehungsweise nicht unbedingt erforderlich.Furthermore, for all of the following dimensions, it must be taken into account that each feature leads to a reduced risk of material failure of the lower and/or upper coupling element. It is essential that the material thickness of the upper coupling element is greater than the material thickness of the lower coupling element. The further dimensions of the subclaims are each advantageous, but not limiting or not absolutely necessary.
Gemäß einer modifizierten Ausführungsform der Erfindung ist vorgesehen, dass die Materialstärke des unteren Koppelelements zwischen der Paneelunterfläche und der Rastaufnahme mindestens einschließlich 62 Prozent, bevorzugt mindestens einschließlich 67 Prozent und besonders bevorzugt mindestens einschließlich 72 Prozent der Materialstärke des oberen Koppelelements zwischen der Paneeloberfläche und der Verriegelungsaufnahme beträgt. Es hat sich herausgestellt, dass durch ein derart dimensioniertes unteres Koppelelement die Neigung zu dessen Materialversagen besonders vorteilhaft reduziert ist, wobei sich dies mit jeder Stufe verbessert, da im unteren Koppelelement zunehmend Material für eine komponentenschonende Kraftflussverteilung vorhanden ist.According to a modified embodiment of the invention, it is provided that the material thickness of the lower coupling element between the lower surface of the panel and the locking receptacle is at least 62 percent, preferably at least 67 percent and particularly preferably at least 72 percent, of the material thickness of the upper coupling element between the panel surface and the locking receptacle . It has been found that a lower coupling element dimensioned in this way increases the tendency for its material to fail is particularly advantageously reduced, with this improving with each stage, since there is increasing material in the lower coupling element for a force flow distribution that is gentle on components.
Gemäß einer modifizierten Ausführungsform der Erfindung ist vorgesehen, dass die Materialstärke des unteren Koppelelements zwischen der Paneelunterfläche und der Rastaufnahme höchstens einschließlich 82 Prozent, höchstens einschließlich 77 Prozent und besonders bevorzugt höchstens einschließlich 72 Prozent der Materialstärke des oberen Koppelelements zwischen der Paneeloberfläche und der Verriegelungsaufnahme beträgt. Hiermit wird eine bevorzugte Höchststeifigkeit des unteren Koppelelements eingestellt, sodass es für die Verbindung zweier Paneele vorteilig flexibel beziehungsweise nachgiebig ist und keine Komponenten aus dem oberen Koppelelement herausbricht.According to a modified embodiment of the invention, it is provided that the material thickness of the lower coupling element between the lower surface of the panel and the locking receptacle is at most 82 percent, at most 77 percent and particularly preferably at most 72 percent of the material thickness of the upper coupling element between the panel surface and the locking receptacle. This sets a preferred maximum rigidity of the lower coupling element, so that it is advantageously flexible or resilient for connecting two panels and no components break out of the upper coupling element.
Gemäß einer modifizierten Ausführungsform der Erfindung ist vorgesehen, dass die Materialstärke des oberen Koppelelements zwischen der Paneeloberfläche und der Verriegelungsaufnahme mindestens einschließlich 34 Prozent, bevorzugt mindestens einschließlich 39 Prozent, besonders bevorzugt mindestens einschließlich 44 Prozent der Gesamtstärke des Paneels beträgt. Es hat sich herausgestellt, dass durch ein derart dimensioniertes oberes Koppelelement seine Neigung zum Materialversagen besonders vorteilhaft reduziert ist, wobei sich dies mit jeder Stufe verbessert, da im oberen Koppelelement zunehmend Material für eine komponentenschonende Kraftflussverteilung vorhanden ist.According to a modified embodiment of the invention, it is provided that the material thickness of the upper coupling element between the panel surface and the locking receptacle is at least 34 percent, preferably at least 39 percent, particularly preferably at least 44 percent, of the total thickness of the panel. It has been found that an upper coupling element dimensioned in this way reduces its tendency to material failure in a particularly advantageous manner, with this improving with each stage since there is increasing material in the upper coupling element for a force flow distribution that is gentle on components.
Gemäß einer modifizierten Ausführungsform der Erfindung ist vorgesehen, dass die Materialstärke des oberen Koppelelements zwischen der Paneeloberfläche und der Verriegelungsaufnahme höchstens einschließlich 54 Prozent, bevorzugt höchstens einschließlich 49 Prozent, besonders bevorzugt höchstens einschließlich 44 Prozent der Gesamtstärke des Paneels beträgt. Hiermit wird eine bevorzugte Höchststeifigkeit des oberen Koppelelements eingestellt, sodass es für die Verbindung zweier Paneele vorteilig flexibel beziehungsweise nachgiebig ist und keine Komponenten aus dem unteren Koppelelement herausbricht.According to a modified embodiment of the invention, it is provided that the material thickness of the upper coupling element between the panel surface and the locking receptacle is at most 54 percent, preferably at most 49 percent, particularly preferably at most 44 percent, of the total thickness of the panel. This sets a preferred maximum rigidity of the upper coupling element, so that it is advantageously flexible or resilient for connecting two panels and no components break out of the lower coupling element.
Gemäß einer modifizierten Ausführungsform der Erfindung ist vorgesehen, dass die Materialstärke des unteren Koppelelements zwischen der Paneelunterfläche und der Rastaufnahme mindestens einschließlich 24 Prozent, bevorzugt mindestens einschließlich 29 Prozent, besonders bevorzugt mindestens einschließlich 34 Prozent der Gesamtstärke des Paneels beträgt. Diese Werte haben sich als bevorzugte Materialstärke erwiesen, um das Risiko eines unerwünschten Materialversagens des unteren Koppelelements weiter zu reduzieren. Dies wird durch ein vorteilhaftes Mindestkraftflussverteilungsvolumen ermöglicht.According to a modified embodiment of the invention, it is provided that the material thickness of the lower coupling element between the bottom surface of the panel and the locking receptacle is at least 24 percent, preferably at least 29 percent, particularly preferably at least 34 percent, of the total thickness of the panel. These values have proven to be the preferred material thickness in order to further reduce the risk of undesirable material failure of the lower coupling element. This is made possible by an advantageous minimum force flow distribution volume.
Gemäß einer modifizierten Ausführungsform der Erfindung ist vorgesehen, dass die Materialstärke des unteren Koppelelements zwischen der Paneelunterfläche und der Rastaufnahme höchstens einschließlich 44 Prozent, bevorzugt höchstens einschließlich 39 Prozent, besonders bevorzugt höchstens einschließlich 34 Prozent der Gesamtstärke des Paneels beträgt. Es hat sich herausgestellt, dass eine derartige Materialstärke des unteren Koppelelements innerhalb dieser Bereiche die Steifigkeit des unteren Koppelelements derart vorteilhaft einstellt, dass sowohl das untere als auch das obere Koppelelement einem Materialversagen besser standhalten.According to a modified embodiment of the invention, it is provided that the material thickness of the lower coupling element between the bottom surface of the panel and the locking receptacle is at most 44 percent, preferably at most 39 percent, particularly preferably at most 34 percent, of the total thickness of the panel. It has been found that such a material thickness of the lower coupling element within these areas advantageously adjusts the rigidity of the lower coupling element in such a way that both the lower and the upper coupling element better withstand material failure.
Erfindungsgemäß ist vorgesehen, dass
- eine zur Verriegelungsaufnahme weisende Verriegelungselementfläche des Verriegelungselements im Wesentlichen eine gleichmäßige Bogenform aufweist und/oder dass
- eine zum Verriegelungselement weisende Verriegelungsaufnahmefläche der Verriegelungsaufnahme eine im Wesentlichen gleichmäßige Bogenform aufweist, wobei die Verriegelungselementfläche und die Verriegelungsaufnahmefläche insbesondere zueinander im Wesentlichen konturgleich ausgebildet sind. Dabei gilt bei mehreren Bogenformen ein Haupterstreckungsbogen als maßgebliche Bogenform, unabhängig dieses Ausführungsbeispiels. Ein Haupterstreckungsbogen ist jener aus mehreren Bögen, dessen Parabelformanteil an der Verriegelungsaufnahme beziehungsweise an dem Verriegelungselement am größten ist. Anders formuliert nimmt der Haupterstreckungsbogen die längste Strecke der Verriegelungsaufnahme beziehungsweise des Verriegelungselements ein. Insbesondere wird das Maß von Haftreibung reduziert, die zu Materialversagen führen könnte. Als im Wesentlichen gleichmäßige Bogenform gelten Bogenformen, die eine gleichmäßige Auflagefläche und somit eine gleichmäßige Kraftverteilung bieten, wobei keine spitzen Winkel hierzu zählen. Dies reduziert das Risiko von Materialversagen am Paneel.
- a locking element surface of the locking element facing the locking receptacle has a substantially uniform arc shape and/or that
- a locking receiving surface of the locking receptacle facing the locking element has a substantially uniform arcuate shape, wherein the locking element surface and the locking receiving surface are designed in particular to have substantially the same contour as one another. In the case of several arch shapes, one main extension arch is considered the relevant arch shape, regardless of this exemplary embodiment. A main extension arc is that of several arcs whose parabolic shape portion on the locking receptacle or on the locking element is largest. In other words, the main extension arc takes up the longest distance of the locking receptacle or the locking element. In particular, the amount of static friction that could lead to material failure is reduced. Than essentially Uniform arch shape refers to arch shapes that offer an even contact surface and thus an even distribution of force, although this does not include acute angles. This reduces the risk of material failure on the panel.
Gemäß einer modifizierten Ausführungsform der Erfindung ist vorgesehen, dass ein Radius der Bogenform der Verriegelungselementfläche und/oder ein Radius der Bogenform der Verriegelungsaufnahmefläche zwischen einschließlich 85 Prozent bis einschließlich 95 Prozent der Gesamtstärke des Paneels beträgt; und bevorzugt in etwa 90 Prozent der Gesamtstärke des Paneels beträgt. Es hat sich herausgestellt, dass innerhalb dieser Werte eine möglichst vorteilhafte und gleichmäßige Kräfteverteilung erfolgt. Durch die jeweils daraus resultierende flache Bogenform sind die Koppelelemente vorteilig vor Haftreibung und somit vor einem Bruchrisiko geschützt.According to a modified embodiment of the invention, it is provided that a radius of the arc shape of the locking element surface and/or a radius of the arc shape of the lock receiving surface is between 85 percent and 95 percent inclusive of the total thickness of the panel; and preferably approximately 90 percent of the total thickness of the panel. It has been found that within these values the most advantageous and even distribution of forces occurs. Due to the resulting flat arch shape, the coupling elements are advantageously protected against static friction and thus against the risk of breakage.
Erfindungsgemäß ist vorgesehen, dass eine Tangente zur Mitte der Bogenform der Verriegelungselementfläche und/oder eine Tangente zur Mitte der Bogenform der Verriegelungsaufnahmefläche gegenüber der Paneeloberfläche und der Paneelunterfläche einen jeweiligen Bogenwinkel kleiner einschließlich 45 Grad, bevorzugt kleiner einschließlich 35 Grad, besonders bevorzugt kleiner einschließlich 25 Grad einschließt oder einschließen. Somit können möglichst viele Vertikalkräfte horizontal gleichmäßig verteilt vom Verriegelungselement des unteren Koppelelements aufgenommen werden. Gleichzeitig ist eine hinreichende Neigung vorhanden, um das dritte Verriegelungssystem zu bilden. Dies wirkt komponentenschonend und paneelsichernd.According to the invention, it is provided that a tangent to the center of the arcuate shape of the locking element surface and/or a tangent to the center of the arcuate shape of the locking receiving surface relative to the panel surface and the panel bottom surface has a respective arc angle of less than 45 degrees, preferably less than 35 degrees, particularly preferably less than 25 degrees includes or includes. This means that as many vertical forces as possible can be absorbed by the locking element of the lower coupling element, evenly distributed horizontally. At the same time there is sufficient inclination to form the third locking system. This protects components and protects the panel.
Erfindungsgemäß ist vorgesehen, dass die Gegenfläche gegenüber der Paneeloberfläche und der Paneelunterfläche einen jeweiligen Gegenflächenwinkel kleiner einschließlich 45 Grad, bevorzugt kleiner einschließlich 35 Grad, besonders bevorzugt kleiner einschließlich 25 Grad einschließt. Somit können möglichst viele Vertikalkräfte horizontal gleichmäßig verteilt von der Gegenfläche des unteren Koppelelements aufgenommen werden. Gleichzeitig ist eine hinreichende Neigung vorhanden, um das erste Verriegelungssystem zu bilden. Dies wirkt komponentenschonend und paneelsichernd.According to the invention, it is provided that the counter surface encloses a respective counter surface angle of less than 45 degrees, preferably less than 35 degrees, particularly preferably less than 25 degrees, relative to the panel surface and the bottom surface of the panel. This means that as many vertical forces as possible can be absorbed horizontally, evenly distributed, by the counter surface of the lower coupling element. At the same time there is sufficient inclination to form the first locking system. This protects components and protects the panel.
Erfindungsgemäß ist vorgesehen, dass der Bogenwinkel und der Gegenflächenwinkel kleiner einschließlich 20 Grad, bevorzugt kleiner einschließlich 15 Grad, besonders bevorzugt kleiner einschließlich 10 Grad voneinander abweichen. Es hat sich herausgestellt, dass es vorteilig ist, den Bogenwinkel und den Gegenflächenwinkel möglichst ähnlich auszubilden, sodass eine gleichmäßige Kraftverteilung erfolgen kann. Insbesondere bei der Montage werden Kräfte gleichmäßig aufgenommen, sodass keine aufeinanderfolgenden Belastungsmaxima entstehen. Besonders bevorzugt entsprechen sich der Bogenwinkel und der Gegenflächenwinkel. Gemäß einer modifizierten Ausführungsform der Erfindung ist vorgesehen, dass
- das Verriegelungselement eine zu der Paneelunterfläche führende Verriegelungsaußenfläche aufweist, die gegenüber einer Vertikalebene einen Verriegelungswinkel kleiner einschließlich 35 Grad, bevorzugt kleiner einschließlich 30 Grad, besonders bevorzugt kleiner einschließlich 25 Grad einschließt. Es hat sich herausgestellt, dass hierdurch vertikal wirkende Kräfte gut in den Untergrund geleitet werden können, wobei das Verriegelungselement möglichst wenig aufgespreizt wird. Gemäß einer modifizierten Ausführungsform der Erfindung ist vorgesehen, dass
- ein Ansatz der Verriegelungsaufnahme übergehend zum Rastelement als Rundung ausgebildet ist. Insbesondere wenn das obere Koppelelement auf das untere Koppelelement aufgesteckt wird, spreizt sich das obere Koppelelement zwischen der Verriegelungsaufnahme und dem Rastelement auf. Durch die Rundung werden Spannungspitzen und somit das Risiko reduziert, dass im Übergang der Verriegelungsaufnahme zum Rastelement ein Materialversagen auftritt.
- the locking element has a locking outer surface leading to the underside of the panel, which, relative to a vertical plane, includes a locking angle of less than 35 degrees, preferably less than 30 degrees, particularly preferably less than 25 degrees. It has been found that this allows vertically acting forces to be well directed into the subsurface, with the locking element being spread as little as possible. According to a modified embodiment of the invention it is provided that
- an approach of the locking receptacle is designed as a curve transitioning to the locking element. In particular, when the upper coupling element is plugged onto the lower coupling element, the upper coupling element spreads between the locking receptacle and the latching element. The rounding reduces stress peaks and thus the risk of material failure occurring in the transition from the locking receptacle to the locking element.
Gemäß einer modifizierten Ausführungsform der Erfindung ist vorgesehen, dass eine zu einem Ansatz der Verriegelungsaufnahme weisende Kante des Verriegelungselements als Rundung ausgebildet ist. Hierdurch wird während der Montage zweier Paneele ein Risiko eines Verkantens des Verriegelungselements des unteren Koppelelements mit dem Rastelement des oberen Koppelelements reduziert. Gemäß einer modifizierten Ausführungsform der Erfindung ist vorgesehen, dass das Rastelement einen Rastvorsprung und die Rastaufnahme ein Rastwiderlager aufweisen, die im gekoppelten Zustand zweier Paneele das zweite Verriegelungssystem bilden. Eine solche Ausgestaltung erlaubt ein zuverlässiges, formschlüssiges zweites Verriegelungssystem, wobei durch das Zusammenspiel von Rastvorsprung und Rastwiderlager das Paneel mit keiner komponentenschädigenden Belastung beaufschlagt wird.According to a modified embodiment of the invention, it is provided that an edge of the locking element facing a projection of the locking receptacle is designed as a curve. This reduces the risk of the locking element of the lower coupling element tilting with the locking element of the upper coupling element during the assembly of two panels. According to a modified embodiment of the invention it is provided that the locking element has a locking projection and the locking receptacle has a locking abutment, which form the second locking system in the coupled state of two panels. Such a configuration allows a reliable, form-fitting second locking system, whereby the interaction of the locking projection and locking abutment means that the panel is not subjected to any load that could damage components.
Gemäß einer modifizierten Ausführungsform der Erfindung ist vorgesehen, dass das Verriegelungselement einen Verriegelungsvorsprung und die Verriegelungsaufnahme ein Verriegelungswiderlager aufweisen, die im gekoppelten Zustand zweier Paneele das dritte Verriegelungssystem bilden. Eine solche Ausgestaltung erlaubt ein zuverlässiges, formschlüssiges drittes Verriegelungssystem, wobei durch das Zusammenspiel von Verriegelungsvorsprung und Verriegelungswiderlager das Paneel mit keiner komponentenschädigenden Belastung beaufschlagt wird.According to a modified embodiment of the invention, it is provided that the locking element has a locking projection and the locking receptacle has a locking abutment, which form the third locking system in the coupled state of two panels. Such a configuration allows a reliable, form-fitting third locking system, whereby the interaction of the locking projection and the locking abutment means that the panel is not subjected to any load that could damage components.
Gemäß einer modifizierten Ausführungsform der Erfindung ist vorgesehen, dass das Paneel zumindest teilweise, bevorzugt vollständig, thermoplastische Styrol-Blockcopolymere, TPS, als Grundwerkstoff aufweist. Es hat sich herausgestellt, dass TPS-haltige Paneele besonders für die beanspruchte Dimensionierung der Koppelelemente geeignet sind. Gleichbedeutend sind hierbei auch Werkstoffe, die ähnliche Eigenschaften wie TPS aufweisen oder die nur teilweise TPS aufweisen.According to a modified embodiment of the invention, it is provided that the panel has at least partially, preferably completely, thermoplastic styrene block copolymers, TPS, as the base material. It has been found that TPS-containing panels are particularly suitable for the stressed dimensions of the coupling elements. The same applies to materials that have similar properties to TPS or that only partially have TPS.
