Definitions

  • the invention relates to a panel, in particular floor panel, comprising a hull with at least one layer of plastic, complementary locking means which are provided in pairs on opposite panel edges, so that several of these panels are locked together, at least one pair of locking means with hook profiles, namely a receiving hook and this opposite a locking hook, with the proviso that the receiving hitch rumpffern arranged a hook edge and fuselage arranged arranged a receiving recess, wherein the receiving recess is open to the top, that the locking hook is provided with a rumpfierr arranged and open to the bottom locking recess and has a fuselage arranged Arretierabsatz, which fits in the vertical joining direction in the receiving recess of the receiving hook that the locking hook a fuselage joint surface and also hull a vertically acting locking contour in that the receiving hook has closer to the joint surface and also closer to the fuselage a form-fitting contour which fits in a form-fitting manner with the locking-far locking contour of the locking hook so that a vertical locking
  • the hook profiles of the known panel are matched to the material from which the hull of the panel is formed. It can catch such panels that have a hull made of a flexible and elastic plastic material.
  • the locking contour which is provided below the joint surface of the locking hook, has areas which protrude with respect to the plane of the joint surface and other areas which are opposite to the plane of the joint surface.
  • the positive locking contour which is provided below the joint surface of the receiving hook, has regions which protrude with respect to the plane of the joint surface, and other regions which protrude from the plane of the joint surface.
  • the mentioned protruding and receding regions of the positive locking contour and the locking contour form undercuts which counteract a movement apart of the two hook profiles in a direction perpendicular to the panel plane (vertical).
  • the locking contour and the positive locking contour are pressed against each other and against each other. They must be elastically deformed.
  • the Arretierkontur and the positive locking contour are soft elastic and can be brought in this way in positive contact with each other. The maximum amount of undercut is limited due to the soft elastic nature of the plastic material. The effect of vertical locking is unsatisfactory.
  • the invention has for its object to improve the panel so that the variety of plastic materials that are used for the trunk increases, and the effect of vertical locking is improved as possible.
  • this object is achieved in that the hull-distant locking contour of the locking hooks protrudes behind the plane of the joint surface of the locking hook, that the hull nearer form-fitting contour of the receiving hook at least partially protrudes beyond the plane of the joint surface of the receiving hook, that locking shoulder and receiving opening are designed so that the paragraph end during a joining movement without elastic deformation of the hook profiles initially fits into the receiving opening so far that the horizontal locking surface of the locking hook with a part of its surface contact with the horizontal locking surface of the receiving hook receives, and that the receiving hook has a bending web which is formed so that by its elastic Biegberry the width of the receiving opening is increased, so that the Arretierabsatz is completely inserted into the receiving recess and also the Arretierkontur the locking hook into the Formschlu sskontur of the receiving hook inserts.
  • the form-fitting contour can, for example, have a latching element which protrudes further than in the prior art, and the arresting contour has a detent recess complementary to the latching element, which is deeper than in the prior art.
  • the Arretierkontur and form-fitting contour can be easily brought into engagement, because of the bend designed to bend elastically and this bend allows widening of the receiving opening. The locking contour and form-fitting contour can thus be moved past each other without strong own deformation until they are engaged.
  • the plastic layer of the hull or core may be formed of a soft and elastic plastic material, such as a thermoplastic polymer, for example polyolefin, polypropylene, polyurethane or polyamide.
  • a soft plastic material and so-called soft PVC comes into question.
  • This is a polyvinyl chloride containing plasticizer.
  • PVC is an amorphous elastomer that has a natural hardness and brittleness that can only be reduced by the plasticizers.
  • the panel is advantageously designed in such a way that it is also possible to produce the plastic layer of the core from a plastic material with natural hardness and brittleness, for example an amorphous elastomer, such as PVC, which contains no or only a small amount of plasticizer.
  • a plastic material with natural hardness and brittleness for example an amorphous elastomer, such as PVC, which contains no or only a small amount of plasticizer.
  • the thickness of the panels according to the invention is 3 to 10 mm, preferably 4 to 8 mm, particularly preferably 5 to 6 mm.
  • the basis weight of the panels is between 1 and 2.5 kg / m 2 , preferably between 1.6 and 1.8 kg / m 2 .
  • Rumpffern may be provided on the hook edge of the receiving hook, a resilient latching tab, wherein the locking recess hull close a recess has, which fits together with the resilient locking tab. In this way, a second point is created within the hook connection, which is to be inserted into each other by elastic deformation of a designated and prepared area, namely the resilient locking tab.
  • the resilient locking tab causes together with the locking recess also a locking of the two hook profiles in the vertical direction, that is perpendicular to the plane of the locked panels.
  • the elastic properties of the hull can be exploited if the resilient locking tab is formed integrally with the hull. If the hull is formed of a relatively hard plastic material, this favors inter alia the production of the resilient snap-in tab by machining production methods, such as milling.
  • the resilient locking tab is rooted on the fuselage side of the hook edge and the free end of the resilient locking tab is inclined from the hook edge, for example, obliquely downwards.
  • the resilient locking tab is always arranged so that a contact with the complementary hook profile produces a compression of the integral locking tab, which moves it closer to the trunk of her panel.
  • the resilient locking tab hulls on a sliding surface. This comes during a vertical joining movement in contact with the locking hook. By this contact, the resilient locking tab is moved closer to the hook edge of the receiving hook. It is stretched elastically in this way and releases the Fügeweg. The locking hook can then be inserted further into the receiving hook until both panels are in one plane.
  • a free space may be provided, in which the locking tab can resiliently spring.
  • the elastic bias allows the resilient latching tab, toward its neutral position spring back when there is room for it.
  • the latching recess expediently has a latching contact surface. This causes by contact with the resilient locking tab locking of connected panels in the vertical direction.
  • the latching contact surface is designed so that it forms a stop bevel for the free end of the resilient latching tab.
  • the stop bevel is designed so that the tensioned locking tab, when it springs back in the direction of its neutral position, abuts against this stop slope. It can be further arranged so that the latching tab abuts before it reaches its neutral position, so that there is always a residual tension in the latching tab, which serves to secure locking.
  • the locking paragraph has on its fuselage side as a sliding slope to be designated oblique sliding surface.
  • the sliding bevel is expediently designed so that it cooperates with that region of the form-fitting contour that protrudes. This projecting from the joint plane region of the positive locking contour, for example, forms a protruding locking element.
  • the protruding portion cooperates with the sliding slope of the Arretierabsatzes. As soon as the sliding bevel comes into contact with the protruding region, for example the detent element, it slides along the detent element. As a result, first the joint surfaces of receiving hook and locking hooks are moved apart.
  • the horizontal locking surface of the locking hook exerts a force which presses against the horizontal locking surface of the receiving hook.
  • This introduced into the horizontal locking surface of the receiving hook force is transmitted to the bending web of the receiving hook, which is thereby bent elastically.
  • the locking contour passes the form-fitting contour until both a Reached position in which they fit positively into one another.
  • the bending stress in the bending web via the horizontal locking surface of the receiving hook exerts a force which biases the joint surface of the locking hook again in the direction of the joint surface of the receiving hook. So a closed joint can be achieved.
  • the horizontal locking surfaces of the two hook profiles are then preferably folded against each other.
  • the degree of bending of the bending web can be influenced.
  • the generated bending stress can be adjusted so that the plastic material is not overloaded in the region of the bending web and takes no damage.
  • a pair of the complementary locking means is formed as pivoting profiles. It is namely a groove profile with undercut a groove wall and a spring profile provided with undercut a spring side.
  • the hook profile of the new panel can be locked with the hook profile of a panel in the same row of panels.
  • the locking hook of the new panel is lowered in a scissors-like motion essentially in a vertical plane and inserted into the receiving hook.
  • the scissor-like movement of the Arretierabsatz initially projects only at one end of the panel edge into the receiving opening.
  • the locking shoulder comes step by step into the receiving opening.
  • the resulting elastic deformation of the bending web is also increasing step by step.
  • the panels are finally in a plane, the locking contour and the form-fitting contour are exactly fitted, the joint surfaces touch and form a closed joint.
  • the bending stress of the bending web is eliminated again and the horizontal locking surfaces of the two hook profiles nestle flat against each other.
  • the area of use can be expanded if a decorative layer is provided on the top side of the panel.
  • a transparent cover layer is provided, through which the cover layer is visible.
  • the transparent cover layer serves to protect the decorative layer. It may be provided with means that reduce wear, such as corundum particles, glass particles, etc. Moreover, it may be useful if a Gegenzug Mrs is provided on the underside of the panel. This acts as a balance to the layers provided at the top to counteract a distortion of the panel.

Aus der WO 2010/015516 ist ein gattungsgemäßes Paneel für Fußböden bekannt. Die Hakenprofile des bekannten Paneels sind abgestimmt auf das Material, aus dem der Rumpf des Paneels ausgebildet ist. Es lassen sich solche Paneele verhaken, die einen Rumpf aus einem biegeweichen und elastischen Kunststoffmaterial aufweisen. Die Arretierkontur, die unterhalb der Fugenfläche des Arretierhakens vorgesehen ist, weist Bereiche auf, welche gegenüber der Ebene der Fugenfläche hervorstehen und andere Bereiche, die gegenüber der Ebene der Fugenfläche zurückstehen. Ebenso weist die Formschlusskontur, die unterhalb der Fugenfläche des Aufnahmehakens vorgesehen ist, Bereiche aufweist, welche gegenüber der Ebene der Fugenfläche hervorstehen, und andere Bereich, die gegenüber der Ebene der Fugenfläche zurückstehen. Die erwähnten hervorstehenden und zurückstehenden Bereiche der Formschlusskontur und der Arretierkontur bilden Hinterschneidungen, welche einem Auseinanderbewegen der beiden Hakenprofile in einer Richtung senkrecht zur Paneelebene (vertikal) entgegenwirken. Um die Hinterschneidungen ineinanderfügen zu können, werden die Arretierkontur und die Formschlusskontur gegeneinander und aneinander vorbei gedrückt. Sie müssen dabei elastisch verformt werden. Die Arretierkontur und die Formschlusskontur sind weichelastisch und können auf diese Weise in formschlüssigen Kontakt miteinander gebracht werden. Das maximale Maß an Hinterschneidung ist aufgrund der weichelastischen Eigenschaft des Kunststoffmaterials begrenzt. Die Wirkung der vertikalen Verriegelung ist unbefriedigend.From the WO 2010/015516 is a generic panel for flooring known. The hook profiles of the known panel are matched to the material from which the hull of the panel is formed. It can catch such panels that have a hull made of a flexible and elastic plastic material. The locking contour, which is provided below the joint surface of the locking hook, has areas which protrude with respect to the plane of the joint surface and other areas which are opposite to the plane of the joint surface. Likewise, the positive locking contour, which is provided below the joint surface of the receiving hook, has regions which protrude with respect to the plane of the joint surface, and other regions which protrude from the plane of the joint surface. The mentioned protruding and receding regions of the positive locking contour and the locking contour form undercuts which counteract a movement apart of the two hook profiles in a direction perpendicular to the panel plane (vertical). In order to be able to join the undercuts together, the locking contour and the positive locking contour are pressed against each other and against each other. They must be elastically deformed. The Arretierkontur and the positive locking contour are soft elastic and can be brought in this way in positive contact with each other. The maximum amount of undercut is limited due to the soft elastic nature of the plastic material. The effect of vertical locking is unsatisfactory.

Der Erfindung liegt die Aufgabe zugrunde, das Paneel so zu verbessern, dass die Vielfalt der Kunststoffmaterialien, die für den Rumpf verwendbar sind, erhöht und die Wirkung der vertikalen Verriegelung möglichst verbessert wird.The invention has for its object to improve the panel so that the variety of plastic materials that are used for the trunk increases, and the effect of vertical locking is improved as possible.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die rumpfferne Arretierkontur des Arretierhakens hinter die Ebene der Fugenfläche des Arretierhakens zurücksteht, dass die rumpfnähere Formschlusskontur des Aufnahmehakens zumindest teilweise über die Ebene der Fugenfläche des Aufnahmehakens hervorsteht, dass Arretierabsatz und Aufnahmeöffnung so gestaltet sind, dass das Absatzende während einer Fügebewegung ohne elastische Verformung der Hakenprofile zunächst soweit in die Aufnahmeöffnung hineinpasst, dass die Horizontalverriegelungsfläche des Arretierhakens mit einem Teil ihrer Fläche Kontakt mit der Horizontalverriegelungsfläche des Aufnahmehakens erhält, und dass der Aufnahmehaken einen Biegesteg aufweist, der so ausgebildet ist, dass durch seine elastische Biegbarkeit die Weite der Aufnahmeöffnung vergrößerbar ist, sodass der Arretierabsatz ganz in die Aufnahmeaussparung einfügbar ist und außerdem die Arretierkontur des Arretierhakens sich in die Formschlusskontur des Aufnahmehakens einfügt.According to the invention, this object is achieved in that the hull-distant locking contour of the locking hooks protrudes behind the plane of the joint surface of the locking hook, that the hull nearer form-fitting contour of the receiving hook at least partially protrudes beyond the plane of the joint surface of the receiving hook, that locking shoulder and receiving opening are designed so that the paragraph end during a joining movement without elastic deformation of the hook profiles initially fits into the receiving opening so far that the horizontal locking surface of the locking hook with a part of its surface contact with the horizontal locking surface of the receiving hook receives, and that the receiving hook has a bending web which is formed so that by its elastic Biegbarkeit the width of the receiving opening is increased, so that the Arretierabsatz is completely inserted into the receiving recess and also the Arretierkontur the locking hook into the Formschlu sskontur of the receiving hook inserts.

Diese Maßnahmen erlauben es, dass die Hakenprofile zu Beginn des Fügeweges in Eingriff kommen, ohne an der Engriffsstelle bereits elastisch verformt zu werden. Erst bei weiterem Fortschritt der Fügebewegung kommen die hinterschnittenen Bereiche von Arretierkontur und Formschlusskontur an der Eingriffsstelle so in Kontakt, dass eine elastische Verformung bewirkt wird, wobei zwecks elastischer Verformung eigens der Biegesteg vorgesehen ist. Zwar werden die Arretierkontur und die Formschlusskontur auch gedrückt und verformt, aber je härter und spröder das Kunststoffmaterial des Rumpfes ist, desto geringer ist die elastische Verformung von Arretierkontur und Formschlusskontur und umso höher ist der Anteil an elastischer Verformung des Biegestegs. Durch diese Gestaltung ist es nun möglich, selbst dann, wenn der Rumpf aus einem relativ harten und spröden Kunststoffmaterial gebildet ist, ein hohes Maß an Hinterschneidung für den Formschluss zwischen der Arretierkontur und Formschlusskontur vorzusehen. Die Formschlusskontur kann zum Beispiel ein Rastelement aufweisen, das weiter hervorsteht, als beim Stand der Technik, und die Arretierkontur eine zum Rastelement komplementäre Rastvertiefung aufweist, die tiefer ist, als beim Stand der Technik. Dennoch können die Arretierkontur und Formschlusskontur problemlos in Eingriff gebracht werden, weil der dazu hergerichtete Biegesteg elastisch biegt und diese Biegung eine Aufweitung der Aufnahmeöffnung ermöglicht. Die Arretierkontur und Formschlusskontur können so ohne starke eigene Verformung aneinander vorbei bewegt werden, bis sie in Eingriff sind.These measures make it possible for the hook profiles to engage at the beginning of the joining path without already being elastically deformed at the point of engagement. Only with further progress of the joining movement come the undercut areas of locking contour and form-fitting contour at the point of engagement in such a way that an elastic deformation is effected, wherein for the purpose of elastic deformation specifically the bending web is provided. Although the Arretierkontur and the positive locking contour are also pressed and deformed, but the harder and brittle the plastic material of the fuselage, the lower the elastic deformation of Arretierkontur and form-fitting contour and the higher the proportion of elastic deformation of the bending web. With this design, it is now possible, even if the hull is formed of a relatively hard and brittle plastic material, a high degree of undercut for the positive connection between the locking contour and positive locking contour provided. The form-fitting contour can, for example, have a latching element which protrudes further than in the prior art, and the arresting contour has a detent recess complementary to the latching element, which is deeper than in the prior art. Nevertheless, the Arretierkontur and form-fitting contour can be easily brought into engagement, because of the bend designed to bend elastically and this bend allows widening of the receiving opening. The locking contour and form-fitting contour can thus be moved past each other without strong own deformation until they are engaged.

Die Kunststoffschicht des Rumpfes beziehungsweise Kerns kann aus einem weichen und elastischen Kunststoffmaterial, wie einem thermoplastischen Polymer, ausgebildet sein, beispielsweise Polyolefin, Polypropylen, Polyurethan oder Polyamid. Als weiches Kunststoffmaterial kommt auch sogenanntes Weich-PVC in Frage. Hierbei handelt es sich um ein Polyvinylchlorid, das Weichmacher enthält. Grundsätzlich ist PVC jedoch ein amorphes Elastomer, das eine natürliche Härte und Sprödigkeit aufweist, die nur durch die Weichmacher vermindert werden kann.The plastic layer of the hull or core may be formed of a soft and elastic plastic material, such as a thermoplastic polymer, for example polyolefin, polypropylene, polyurethane or polyamide. As a soft plastic material and so-called soft PVC comes into question. This is a polyvinyl chloride containing plasticizer. Basically, however, PVC is an amorphous elastomer that has a natural hardness and brittleness that can only be reduced by the plasticizers.

Vorteilhaft ist das Paneel jedoch so gestaltet, dass es auch möglich ist, die Kunststoffschicht des Kerns aus einem Kunststoffmaterial mit natürlicher Härte und Sprödigkeit herzustellen, beispielsweise einem amorphen Elastomer, wie PVC, das gar keine oder nur eine geringe Menge Weichmacher enthält.However, the panel is advantageously designed in such a way that it is also possible to produce the plastic layer of the core from a plastic material with natural hardness and brittleness, for example an amorphous elastomer, such as PVC, which contains no or only a small amount of plasticizer.

Je nach Ausführungsform der Erfindung beträgt die Dicke der erfindungsgemäßen Paneele 3 bis 10 mm, vorzugsweise 4 bis 8 mm, besonders bevorzugt 5 bis 6 mm. Das Flächengewicht der Paneele liegt je nach Dicke und spezifischem Aufbau zwischen 1 bis 2,5 kg/m2, vorzugsweise zwischen 1,6 und 1,8 kg/m2.Depending on the embodiment of the invention, the thickness of the panels according to the invention is 3 to 10 mm, preferably 4 to 8 mm, particularly preferably 5 to 6 mm. Depending on the thickness and specific structure, the basis weight of the panels is between 1 and 2.5 kg / m 2 , preferably between 1.6 and 1.8 kg / m 2 .

Rumpffern kann an dem Hakenrand des Aufnahmehakens eine federnde Rastlasche vorgesehen sein, wobei die Arretieraussparung rumpfnah eine Rastausnehmung aufweist, die mit der federnden Rastlasche zusammenpasst. Auf diese Weise ist eine zweite Stelle innerhalb der Hakenverbindung geschaffen, die durch elastische Verformung eines dazu vorgesehenen und hergerichteten Bereiches, nämlich der federnden Rastlasche, ineinander zu fügen ist. Die federnde Rastlasche bewirkt zusammen mit der Arretieraussparung ebenfalls eine Verriegelung der beiden Hakenprofile in vertikaler Richtung, also senkrecht zur Ebene der verriegelten Paneele.Rumpffern may be provided on the hook edge of the receiving hook, a resilient latching tab, wherein the locking recess hull close a recess has, which fits together with the resilient locking tab. In this way, a second point is created within the hook connection, which is to be inserted into each other by elastic deformation of a designated and prepared area, namely the resilient locking tab. The resilient locking tab causes together with the locking recess also a locking of the two hook profiles in the vertical direction, that is perpendicular to the plane of the locked panels.

Die elastischen Eigenschaften des Rumpfes können ausgenutzt werden, wenn die federnde Rastlasche einstückig mit dem Rumpf ausgebildet ist. Ist der Rumpf aus einem relativ harten Kunststoffmaterial gebildet, begünstigt dies unter anderem die Herstellung der federnden Rastlasche durch spanende Fertigungsverfahren, wie Fräsen.The elastic properties of the hull can be exploited if the resilient locking tab is formed integrally with the hull. If the hull is formed of a relatively hard plastic material, this favors inter alia the production of the resilient snap-in tab by machining production methods, such as milling.

Die federnde Rastlasche wurzelt an der rumpffernen Seite des Hakenrands und das freie Ende der federnden Rastlasche steht von dem Hakenrand schräg ab, beispielsweise schräg nach unten. Die federnde Rastlasche ist stets so angeordnet, dass ein Kontakt mit dem komplementären Hakenprofil ein Einfedern der einstückigen Rastlasche erzeugt, welches diese näher an den Rumpf ihres Paneels heranbewegt.The resilient locking tab is rooted on the fuselage side of the hook edge and the free end of the resilient locking tab is inclined from the hook edge, for example, obliquely downwards. The resilient locking tab is always arranged so that a contact with the complementary hook profile produces a compression of the integral locking tab, which moves it closer to the trunk of her panel.

Zweckmäßig weist die federnde Rastlasche rumpffern eine Gleitfläche auf. Diese kommt während einer vertikalen Fügebewegung in Kontakt mit dem Arretierhaken. Durch diese Berührung wird die federnde Rastlasche näher an den Hakenrand des Aufnahmehakens heranbewegt. Sie wird auf diese Weise elastisch gespannt und gibt den Fügeweg frei. Der Arretierhaken kann dann weiter in den Aufnahmehaken eingefügt werden, bis sich beide Paneele in einer Ebene befinden.Suitably, the resilient locking tab hulls on a sliding surface. This comes during a vertical joining movement in contact with the locking hook. By this contact, the resilient locking tab is moved closer to the hook edge of the receiving hook. It is stretched elastically in this way and releases the Fügeweg. The locking hook can then be inserted further into the receiving hook until both panels are in one plane.

Zwischen der federnden Rastlasche und dem Hakenrand kann ein Freiraum vorgesehen sein, in den die Rastlasche elastisch einfedern kann. Die elastische Vorspannung ermöglicht es der federnden Rastlasche, in Richtung ihrer neutralen Position zurückzufedern, wenn sich Raum dafür bietet.Between the resilient locking tab and the hook edge, a free space may be provided, in which the locking tab can resiliently spring. The elastic bias allows the resilient latching tab, toward its neutral position spring back when there is room for it.

Zweckmäßig weist die Rastausnehmung eine Rastkontaktfläche auf. Diese bewirkt durch Kontakt mit der federnden Rastlasche eine Arretierung verbundener Paneele in vertikaler Richtung.The latching recess expediently has a latching contact surface. This causes by contact with the resilient locking tab locking of connected panels in the vertical direction.

Vorzugsweise ist die Rastkontaktfläche so gestaltet, dass sie eine Anschlagschräge für das freie Ende der federnden Rastlasche bildet. Die Anschlagschräge ist so gestaltet, dass die gespannte Rastlasche, wenn sie in Richtung ihrer neutralen Position zurückfedert, gegen diese Anschlagschräge stößt. Sie kann weiter so angeordnet sein, dass die Rastlasche anstößt, bevor sie ihre neutrale Position erreicht, sodass stets ein Rest Spannung in der Rastlasche erhalten bleibt, die einer sicheren Arretierung dient.Preferably, the latching contact surface is designed so that it forms a stop bevel for the free end of the resilient latching tab. The stop bevel is designed so that the tensioned locking tab, when it springs back in the direction of its neutral position, abuts against this stop slope. It can be further arranged so that the latching tab abuts before it reaches its neutral position, so that there is always a residual tension in the latching tab, which serves to secure locking.

Als weiterer Vorteil wird es angesehen, wenn der Arretierabsatz auf seiner rumpffernen Seite eine als Gleitschräge zu bezeichnende schräge Gleitfläche aufweist. Die Gleitschräge ist zweckmäßig so gestaltet, dass sie mit demjenigen Bereich der Formschlusskontur zusammenwirkt, der hervorsteht. Dieser von der Fugenebene hervorstehende Bereich der Formschlusskontur, bildet beispielsweise ein hervorstehendes Rastelement. Der hervorstehende Bereich wirkt mit der Gleitschräge des Arretierabsatzes zusammen. Sobald die Gleitschräge mit dem hervorstehenden Bereich, beispielsweise dem Rastelement, in Kontakt kommt, gleitet sie an dem Rastelement entlang. Dadurch werden zunächst die Fugenflächen von Aufnahmehaken und Arretierhaken auseinander bewegt. Gleichzeitig übt die Horizontalverriegelungsfläche des Arretierhakens eine Kraft aus, die gegen die Horizontalverriegelungsfläche des Aufnahmehakens drückt. Diese in die Horizontalverriegelungsfläche des Aufnahmehakens eingeleitete Kraft wird in den Biegesteg des Aufnahmehakens übertragen, der sich dadurch elastisch gebogen wird. Bei der weiteren Fügebewegung passiert die Arretierkontur die Formschlusskontur soweit, bis beide eine Position erreicht haben, in der sie formschlüssig ineinander passen. Dabei übt die Biegespannung in dem Biegesteg über die Horizontalverriegelungsfläche des Aufnahmehakens eine Kraft aus, welche die Fugenfläche des Arretierhakens wieder in Richtung der Fugenfläche des Aufnahmehakens vorspannt. So kann eine geschlossene Fuge erreicht werden. Die Horizontalverriegelungsflächen der beiden Hakenprofile sind dann vorzugsweise aneinandergeschmiegt.As a further advantage, it is considered that the locking paragraph has on its fuselage side as a sliding slope to be designated oblique sliding surface. The sliding bevel is expediently designed so that it cooperates with that region of the form-fitting contour that protrudes. This projecting from the joint plane region of the positive locking contour, for example, forms a protruding locking element. The protruding portion cooperates with the sliding slope of the Arretierabsatzes. As soon as the sliding bevel comes into contact with the protruding region, for example the detent element, it slides along the detent element. As a result, first the joint surfaces of receiving hook and locking hooks are moved apart. At the same time, the horizontal locking surface of the locking hook exerts a force which presses against the horizontal locking surface of the receiving hook. This introduced into the horizontal locking surface of the receiving hook force is transmitted to the bending web of the receiving hook, which is thereby bent elastically. During the further joining movement, the locking contour passes the form-fitting contour until both a Reached position in which they fit positively into one another. The bending stress in the bending web via the horizontal locking surface of the receiving hook exerts a force which biases the joint surface of the locking hook again in the direction of the joint surface of the receiving hook. So a closed joint can be achieved. The horizontal locking surfaces of the two hook profiles are then preferably folded against each other.

Durch die geometrische Form der Gleitschräge (linear oder kurvig) ist der Grad der Biegung des Biegestegs beeinflussbar. Durch Variation der Gleitschräge kann die erzeugte Biegespannung so abgestimmt werden, dass das Kunststoffmaterial im Bereich des Biegestegs nicht überlastet wird und keinen Schaden nimmt.Due to the geometric shape of the sliding bevel (linear or curved), the degree of bending of the bending web can be influenced. By varying the slip angle, the generated bending stress can be adjusted so that the plastic material is not overloaded in the region of the bending web and takes no damage.

Ein Paar der komplementären Verriegelungsmittel ist als Schwenkprofile ausgebildet. Es ist nämlich ein Nutprofil mit Hinterschneidung einer Nutwand und einem Federprofil mit Hinterschneidung einer Federseite vorgesehen.A pair of the complementary locking means is formed as pivoting profiles. It is namely a groove profile with undercut a groove wall and a spring profile provided with undercut a spring side.

Dies hat den Vorteil, dass Paneele sich zweckmäßigerweise so verlegen lassen, dass ein neues Paneel mit einem Schwenkprofil an das komplementäre Schwenkprofil eines schon in der Verlegeebene liegenden Paneels an angesetzt und herabgeschwenkt wird.This has the advantage that panels can expediently be laid so that a new panel with a pivoting profile is attached to the complementary pivot profile of a lying in the laying plane panel and lowered down.

Vorteilhaft kann dabei gleichzeitig das Hakenprofil des neuen Paneels mit dem Hakenprofil eines Paneels in derselben Paneelreihe verriegelt werden. Zu dem Zweck wird der Arretierhaken des neuen Paneels in einer scherenartigen Bewegung im Wesentlichen in einer vertikalen Ebene abgesenkt und in den Aufnahmehaken eingefügt. Während der scherenartigen Bewegung ragt der Arretierabsatz zunächst nur an einem Ende der Paneelkante in die Aufnahmeöffnung hinein. Beim Fortschreiten der scherenartigen Fügebewegung kommt der Arretierabsatz Schritt für Schritt in die Aufnahmeöffnung. Die dadurch eingeleitete elastische Verformung des Biegestegs nimmt ebenfalls Schritt für Schritt zu. Wenn die Paneele in sich schließlich in einer Ebene befinden sind die Arretierkontur und die Formschlusskontur exakt eingepasst, die Fugenflächen berühren sich und bilden eine geschlossene Fuge. Außerdem ist die Biegespannung des Biegestegs wieder eliminiert und die Horizontalverriegelungsflächen der beiden Hakenprofile schmiegen sich flächig aneinander.Advantageously, at the same time the hook profile of the new panel can be locked with the hook profile of a panel in the same row of panels. For this purpose, the locking hook of the new panel is lowered in a scissors-like motion essentially in a vertical plane and inserted into the receiving hook. During the scissor-like movement of the Arretierabsatz initially projects only at one end of the panel edge into the receiving opening. As the scissor-type joining movement proceeds, the locking shoulder comes step by step into the receiving opening. The resulting elastic deformation of the bending web is also increasing step by step. When the panels are finally in a plane, the locking contour and the form-fitting contour are exactly fitted, the joint surfaces touch and form a closed joint. In addition, the bending stress of the bending web is eliminated again and the horizontal locking surfaces of the two hook profiles nestle flat against each other.

Der Einsatzbereich lässt sich erweitern, wenn an der Oberseite des Paneels eine Dekorschicht vorgesehen ist. Ein weiterer Nutzen ergibt sich dadurch, dass eine transparente Deckschicht vorgesehen ist, durch welche die Deckschicht sichtbar ist. Die transparente Deckschicht dient zum Schutz der Dekorschicht. Sie kann mit Mitteln versehen sein, welche den Verschleiß mindern, beispielsweise Korundpartikel, Glaspartikel, etc. Darüber hinaus kann es nützlich sein, wenn an der Unterseite des Paneels eine Gegenzugschicht vorgesehen ist. Diese wirkt als Balance zu den an der Oberseite vorgesehenen Schichten, um einem Verzug des Paneels entgegenzuwirken.The area of use can be expanded if a decorative layer is provided on the top side of the panel. Another benefit is that a transparent cover layer is provided, through which the cover layer is visible. The transparent cover layer serves to protect the decorative layer. It may be provided with means that reduce wear, such as corundum particles, glass particles, etc. Moreover, it may be useful if a Gegenzugschicht is provided on the underside of the panel. This acts as a balance to the layers provided at the top to counteract a distortion of the panel.

Die Figuren 1a bis 1d zeigen jeweils ausschnittsweise zwei Paneele 1 beziehungsweise 2. Die Paneele 1 und 2 sind identisch. Jedes einzelne Paneel weist an gegenüberliegenden Paneelkanten eines Kantenpaares komplementäre Profile 3 beziehungsweise 4 auf. Bei dem Paneel 1 weist daher die nicht dargestellte Kante identisch das Profil 4 des Paneels 2 auf und bei dem Paneel 2 weist die nicht dargestellte Kante identisch das Profil 3 des Paneels 1 auf.The FIGS. 1a to 1d each show a detail of two panels 1 and 2, respectively. The panels 1 and 2 are identical. Each individual panel has complementary profiles 3 and 4, respectively, on opposite panel edges of an edge pair. In the panel 1, therefore, the edge, not shown, identical to the profile 4 of the panel 2 and in the panel 2, the edge, not shown, identical to the profile 3 of the panel 1 on.

Bei einem Paneel mit vier Kanten, kann das zweite Kantenpaar mit komplementären Profilen ausgebildet sein, die mit den Profilen des ersten Kantenpaares identisch sind.In a panel with four edges, the second edge pair may be formed with complementary profiles that are identical to the profiles of the first edge pair.

Die Serie der Figuren 1a bis 1d verdeutlicht in mehreren Schritten den prinzipiellen Ablauf der Fügebewegung zwecks Verbindung und Verriegelung der Paneele 1 und 2.The series of FIGS. 1a to 1d illustrates in several steps the basic sequence of the joining movement for the purpose of connection and locking of the panels 1 and 2.

Die komplementären Profile 3 und 4 eines jeden Paneels 1 beziehungsweise 2 bilden komplementäre Verriegelungsmittel V in Form von Hakenprofilen H. Das Hakenprofil des Profils 1 bildet einen Aufnahmehaken 5 und das Hakenprofil des Profils 2 einen Arretierhaken 6, der in den Aufnahmehaken 5 passt, wobei die beiden Hakenprofile so gestaltet sind, dass eine Arretierung erfolgt. Die Arretierung wirkt einer Umkehrung der Fügebewegung entgegen. Die Paneele 1 und 2 können so nach erfolgter Verriegelung nicht in einer Rückwärtsbewegung wieder voneinander gelöst werden.The complementary profiles 3 and 4 of each panel 1 and 2 form complementary locking means V in the form of hook profiles H. The hook profile of the profile 1 forms a receiving hook 5 and the hook profile of the profile 2 a locking hook 6, which fits into the receiving hooks 5, wherein the Both hook profiles are designed so that a lock takes place. The locking counteracts a reversal of the joining movement. The panels 1 and 2 can not be released from each other in a backward movement so after locking.

Jedes Paneel 1 beziehungsweise 2 umfasst einen Rumpf 1' beziehungsweise 2' mit einer Kunststoffschicht, an der die erwähnten komplementären Verriegelungsmittel V angeordnet sind. Eine Oberseite 7 des Paneels bildet eine Nutzoberfläche.Each panel 1 or 2 comprises a hull 1 'or 2' with a plastic layer on which the mentioned complementary locking means V are arranged. An upper side 7 of the panel forms a useful surface.

An dem Aufnahmehaken 5 ist rumpffern ein Hakenrand 8 und rumpfnäher eine Aufnahmeaussparung 9 vorgesehen. Die Aufnahmeaussparung 9 ist zur Oberseite 7 offen.At the receiving hook 5 is a hull ram a hook edge 8 and fuddle closer a receiving recess 9 is provided. The receiving recess 9 is open to the top 7.

Der Arretierhaken 6 ist mit einer rumpfnäher angeordneten und zur Unterseite 10 offenen Arretieraussparung 11 versehen und weist rumpffern einen Arretierabsatz 12 auf. Der Arretierabsatz passt in vertikaler Fügerichtung T in die Aufnahmeaussparung 9 des Aufnahmehakens 5. Weiterhin weist der Arretierhaken 6 eine rumpfferne Fugenfläche 13 und gleichfalls rumpffern eine vertikal verriegelnd wirkende Arretierkontur 14 auf. Der Aufnahmehaken 5 weist rumpfnah eine Fugenfläche und gleichfalls rumpfnah eine Formschlusskontur 16 auf, die formschlüssig mit der Arretierkontur 14 des Arretierhakens 6 zusammenpasst. Auf diese Weise ist eine vertikale Verriegelung bewirkbar.The locking hook 6 is provided with a rumpfnäher arranged and open to the bottom 10 locking recess 11 and has fuselage a locking shoulder 12. The locking shoulder fits in the vertical joining direction T in the receiving recess 9 of the receiving hook 5. Furthermore, the locking hook 6 has a fuselage joint surface 13 and also hull a vertically locking locking detent 14 acting on. The receiving hook 5 has a joint surface close to the fuselage and, likewise close to the fuselage, a form-fitting contour 16, which mates with the locking contour 14 of the locking hook 6 in a form-fitting manner. In this way, a vertical lock can be effected.

Außerdem weist der Arretierhaken 6 rumpfnah angeordnet eine Horizontalverriegelungsfläche 17 auf, die an seinem Arretierabsatz 12 angeordnet ist. Passend dazu weist der Aufnahmehaken 5, rumpffern in der Aufnahmeaussparung 9 angeordnet, eine Horizontalverriegelungsfläche 18 auf, die mit der Horizontalverriegelungsfläche 17 des Arretierhakens 6 zusammenwirkt.In addition, the locking hook 6 has arranged close to the hull a horizontal locking surface 17, which is arranged at its Arretierabsatz 12. Fits thereto, the receiving hooks 5, arranged hull-distant in the receiving recess 9, a horizontal locking surface 18 which cooperates with the horizontal locking surface 17 of the locking hook 6.

Der Aufnahmehaken 5 ist an seiner Aufnahmeaussparung 9 mit einer verengten Aufnahmeöffnung 19 versehen. Der Arretierabsatz 12 ist im Wesentlichen in vertikaler Fügerichtung T in die Aufnahmeaussparung 9 einfügbar, dass heißt in einer Ebene senkrecht zur Ebene der verriegelten Paneele.The receiving hook 5 is provided at its receiving recess 9 with a narrowed receiving opening 19. The Arretierabsatz 12 is inserted substantially in the vertical joining direction T in the receiving recess 9, that is, in a plane perpendicular to the plane of the locked panels.

Gemäß den Figuren 1a bis 1d ist das Paneel 1 mit dem Aufnahmehaken 5 auf einem festen Untergrund (nicht dargestellt) angeordnet. Der Arretierabsatz 12 des Paneels 2 wird senkrecht zur Paneelebene (vertikal) abgesenkt. Die rumpfferne Arretierkontur 14 des Arretierhakens 5 weist eine Rastvertiefung 14a auf, die hinter die Ebene der Fugenfläche 13 des Arretierhakens 6 zurücksteht. Die rumpfnahe Formschlusskontur 16 des Aufnahmehakens 5 ist so gestaltet, dass sie ein Rastelement 16a aufweist, das über die Ebene der Fugenfläche 15 des Aufnahmehakens 5 hervorsteht und im verriegelten Zustand in die Rastvertiefung 14a des Arretierhakens 6 hineingreift/hintergreift. Im Übrigen sind Arretierabsatz 12 und Aufnahmeöffnung 19 so gestaltet, dass das freie Absatzende des Arretierabsatzes 12 während des Beginns der Fügebewegung zunächst ohne nennenswerte elastische Verformung der Hakenprofile in die Aufnahmeöffnung 19 hineinpasst. Dabei kommt die Horizontalverriegelungsfläche 17 des Arretierhakens 6 mit einem Teil ihrer Fläche in Kontakt mit der Horizontalverriegelungsfläche 18 des Aufnahmehakens 5.According to the FIGS. 1a to 1d the panel 1 is arranged with the receiving hook 5 on a solid surface (not shown). The Arretierabsatz 12 of the panel 2 is lowered perpendicular to the panel plane (vertical). The hull-distant locking contour 14 of the locking hook 5 has a latching recess 14a, which projects behind the plane of the joint surface 13 of the locking hook 6. The close-fitting form-fitting contour 16 of the receiving hook 5 is designed so that it has a locking element 16a which projects beyond the plane of the joint surface 15 of the receiving hook 5 and engages in the locked state in the locking recess 14a of the locking hook 6 / engages behind. Incidentally, locking shoulder 12 and receiving opening 19 are designed so that the free paragraph end of Arretierabsatzes 12 fits during the beginning of the joining movement initially without significant elastic deformation of the hook profiles in the receiving opening 19. In this case, the horizontal locking surface 17 of the locking hook 6 comes with a part of its surface in contact with the horizontal locking surface 18 of the receiving hook. 5

An dem Aufnahmehaken 5 ist ein besonderer Biegesteg 20 ausgebildet, der am Besten in den Figuren 1b und 1c zu erkennen ist. Der Biegesteg 20 ist so gestaltet, dass durch seine elastische Biegbarkeit die Weite der Aufnahmeöffnung 19 vergrößerbar ist, sodass der Arretierabsatz 12 problemlos in die Aufnahmeaussparung 9 einfügbar ist. Außerdem ist wegen der Biegbarkeit des Biegestegs 20 die Arretierkontur 14 des Arretierhakens 6 sehr einfach in die Formschlusskontur 16 des Aufnahmehakens 5 einfügbar.On the receiving hook 5, a special bending web 20 is formed, the best in the Figures 1b and 1c can be seen. The bending web 20 is designed so that the width of the receiving opening 19 can be increased by its elastic bendability, so that the locking shoulder 12 can be easily inserted into the receiving recess 9. In addition, because of the flexibility of the bending web 20, the locking contour 14 of the locking hook 6 can be inserted very easily into the positive locking contour 16 of the receiving hook 5.

Die Hakenprofile sind zu Beginn des Fügeweges in Eingriff zu bringen, ohne an der Engriffsstelle bereits elastisch verformt zu werden. Erst bei weiterem Fortschritt der Fügebewegung kommen die hinterschnittenen Bereiche von Arretierkontur 14 und Formschlusskontur 16 an der Eingriffsstelle in Kontakt. Dieser Kontakt bewirkt jedoch eine elastische Verformung, die im Wesentlichen an einer anderen Stelle stattfindet, nämlich an dem dafür vorgesehenen Biegesteg 20. Zwar werden die Arretierkontur 14 und die Formschlusskontur 16 auch gedrückt und verformt, aber je härter und spröder das Kunststoffmaterial des Rumpfes ist, desto geringer ist die elastische Verformung von Arretierkontur 14 und Formschlusskontur 16 und umso höher ist der Anteil der elastischen Verformung des Biegestegs 20.The hook profiles are to be brought into engagement at the beginning of the joining path, without being already elastically deformed at the Engriffsstelle. Only with further progress of the joining movement, the undercut areas of Arretierkontur 14 and Formschlusskontur 16 come into contact at the intervention site. However, this contact causes an elastic deformation, which takes place substantially at a different location, namely at the designated bending web 20. Although the locking contour 14 and the positive locking contour 16 are also pressed and deformed, but the harder and brittle the plastic material of the fuselage, the smaller the elastic deformation of the locking contour 14 and the positive locking contour 16, and the higher the proportion of the elastic deformation of the bending web 20.

Die Rastvertiefung 14a des Arretierhakens 6 ist tiefer gestaltet, als beim Stand der Technik. Ebenso steht das Rastelement 16a des Aufnahmehakens 5 weiter von der Fugenfläche 15 des Aufnahmehakens 5 hervor, als beim Stand der Technik. Dadurch ergibt sich in der vertikalen Fügerichtung ein höheres Maß an Hinterschneidung als beim Stand der Technik. Trotzdem können die Arretierkontur 14 und Formschlusskontur 16 problemlos in Eingriff gebracht werden. Dies, weil der Biegesteg 20 so elastisch biegbar ist, dass diese Biegung eine Aufweitung der Aufnahmeöffnung 19 ermöglicht. Die Arretierkontur 14 und Formschlusskontur 16 können so ohne starke eigene Verformung aneinander vorbei bewegt werden, bis sie sich in formschlüssigem Eingriff befinden und ihre vertikale Verriegelungswirkung entfalten.The locking recess 14a of the locking hook 6 is designed deeper than in the prior art. Likewise, the locking element 16a of the receiving hook 5 protrudes further from the joint surface 15 of the receiving hook 5, as in the prior art. This results in the vertical joining direction, a higher degree of undercut than in the prior art. Nevertheless, the locking contour 14 and form-fitting contour 16 can be easily brought into engagement. This is because the bending web 20 is elastically bendable so that this bend allows widening of the receiving opening 19. The Arretierkontur 14 and positive locking contour 16 can be moved past each other without strong own deformation until they are in positive engagement and unfold their vertical locking action.

In Fig. 1b ist dargestellt, dass eine schräge Fläche rumpffern an dem Arretierabsatz 12 vorgesehen ist, die eine Gleitschräge 12a bildet. Die Gleitschräge berührt das hervorstehende Rastelement 16a der Formschlusskontur 16 des Aufnahmehakens. Während der vertikalen Fügebewegung des Arretierhakens 6 wird dadurch eine horizontale Bewegung überlagert, welche die Paneele auseinander bewegt, sodass sich zwischen den Fugenflächen 13, 15 ein Abstand bildet. Gleichzeitig übt die Horizontalverriegelungsfläche 17 des Arretierhakens 6 eine Kraft aus, die gegen die Horizontalverriegelungsfläche 18 des Aufnahmehakens 5 drückt. Die Kraft, die auf die Horizontalverriegelungsfläche 18 des Aufnahmehakens 5 wirkt, wird in den Biegesteg 20 des Aufnahmehakens 5 übertragen, der dadurch elastisch gebogen wird.In Fig. 1b It is shown that a sloping surface is provided on the locking shoulder 12, which forms a sliding bevel 12a. The sliding bevel contacts the protruding latching element 16a of the positive locking contour 16 of the receiving hook. During the vertical joining movement of the locking hook 6, a horizontal movement is superimposed thereby, which moves the panels apart so that a gap is formed between the joint surfaces 13, 15. At the same time, the horizontal locking surface 17 of the locking hook 6 exerts a force which presses against the horizontal locking surface 18 of the receiving hook 5. The force acting on the horizontal locking surface 18 of the receiving hook 5 is transmitted to the bending web 20 of the receiving hook 5, which is thereby elastically bent.

Bei der weiteren Fügebewegung gemäß Fig. 1c passiert die weiteste Stelle des Arretierabsatzes 12 die aufgeweitete Aufnahmeöffnung 19 der Aufnahmeaussparung 9. Anschließend nimmt die Biegung des Biegestegs 20 ab, und die Aufnahmeöffnung 19 verengt sich wieder. Die im Abstand k befindlichen Fugenflächen 13, 15 der Paneele werden durch die Biegespannung des Biegestegs 20 aufeinander zu gedrückt.In the further joining movement according to Fig. 1c the widest point of Arretierabsatzes 12 passes the widened receiving opening 19 of the receiving recess 9. Then the bending of the bending web 20 decreases, and the receiving opening 19 narrows again. The joint surfaces located at a distance k 13, 15 of the panels are pressed by the bending stress of the bending web 20 toward each other.

In Fig. 1d haben die Arretierkontur 14 und die Formschlusskontur 16 eine Position erreicht, in der sie formschlüssig ineinander passen. Die Hakenprofile H können so ausgelegt sein, dass ein Rest Biegespannung des Biegestegs 20 erhalten bleibt und über die Horizontalverriegelungsfläche 18 des Aufnahmehakens 5 eine elastische Kraft (Federkraft) ausgeübt wird, welche die Fugenfläche 13 des Arretierhakens 6 permanent in Richtung der Fugenfläche 15 des Aufnahmehakens 5 vorspannt. So kann dauerhaft eine geschlossene Fuge erreicht werden. In Fig. 1d sind die Horizontalverriegelungsflächen 17, 18 der beiden Hakenprofile H aneinandergeschmiegt und üben keine permanente Vorspannung aus.In Fig. 1d the locking contour 14 and the positive locking contour 16 have reached a position in which they fit one another in a form-fitting manner. The hook profiles H can be designed so that a residual bending stress of the bending web 20 is maintained and on the horizontal locking surface 18 of the receiving hook 5, an elastic force (spring force) is exerted, which the joint surface 13 of the locking hook 6 permanently in the direction of the joint surface 15 of the receiving hook. 5 biases. This way, a closed joint can be permanently achieved. In Fig. 1d the horizontal locking surfaces 17, 18 of the two hook profiles H are folded against each other and do not exert a permanent bias.

Die Figuren 2a bis 2d zeigen jeweils ausschnittsweise zwei Paneele 1 beziehungsweise 2. Diese sind wiederum identisch. Jedes einzelne Paneel weist an gegenüberliegenden Paneelkanten eines Kantenpaares die dargestellten komplementären Profile auf. Bei einem Paneel mit vier Kanten kann das zweite Kantenpaar mit komplementären Profilen ausgebildet sein, die mit den Paneelkanten des ersten Kantenpaares identisch sind.The FIGS. 2a to 2d each show a fragmentary two panels 1 and 2. These are in turn identical. Each individual panel has on opposing panel edges of an edge pair the complementary profiles shown. In a panel with four edges, the second edge pair may be formed with complementary profiles that are identical to the panel edges of the first edge pair.

Die Serie der Figuren verdeutlicht wiederum in mehreren Schritten 2a bis 2d den prinzipiellen Ablauf der Fügebewegung zur Verbindung und Verriegelung der Paneele.The series of figures again illustrates in several steps 2a to 2d the basic sequence of the joining movement for connecting and locking the panels.

Das Ausführungsbeispiel des Paneels 1 beziehungsweise 2 gemäß den Figuren 2a bis 2d entspricht weitgehend dem Ausführungsbeispiel gemäß den Figuren 1a bis 1d. Insofern werden für identische Merkmale die gleichen Bezugszeichen verwendet, wie in den Figuren 1a bis 1d. Gemäß den Figuren 2a bis 2d ist eine zweite formschlüssige Verriegelung vorgesehen. Zu diesem Zweck ist eine federnde Rastlasche vorgesehen, die an dem Hakenrand 8 des Aufnahmehakens 5 wurzelt. Die Arretieraussparung 11 weist rumpfnah eine Rastausnehmung 22 auf, die mit der federnden Rastlasche 21 zusammenpasst. Auf diese Weise ist eine zweite Stelle innerhalb einer Hakenverbindung geschaffen, die durch elastische Verformung eines dazu vorgesehenen und hergerichteten Bereiches, nämlich der federnden Rastlasche 21, problemlos ineinander zu fügen ist. Die federnde Rastlasche 21 bewirkt zusammen mit der Arretieraussparung 9 ebenfalls eine Verriegelung der beiden Hakenprofile H in vertikaler Richtung, also senkrecht zur Ebene der verriegelten Paneele.The embodiment of the panel 1 or 2 according to the FIGS. 2a to 2d largely corresponds to the embodiment according to the FIGS. 1a to 1d , In this respect, the same reference numerals are used for identical features as in the FIGS. 1a to 1d , According to the FIGS. 2a to 2d a second positive locking is provided. For this purpose, a resilient locking tab is provided, which is rooted on the hook edge 8 of the receiving hook 5. The locking recess 11 has a recess near the fuselage 22, which mates with the resilient locking tab 21. In this way, a second location is created within a hook connection provided by elastic deformation of a designated and prepared area, namely the resilient latching tab 21, is easy to fit into each other. The resilient latching tab 21 causes together with the locking recess 9 also a locking of the two hook profiles H in the vertical direction, ie perpendicular to the plane of the locked panels.

Die federnde Rastlasche 21 ist einstückig mit dem Rumpf ausgebildet. Insofern werden die elastischen Eigenschaften des Rumpfes ausgenutzt. Es ist günstig für den verriegelnden Effekt der federnden Rastlasche 21, wenn das Kunststoffmaterial des Rumpfes relativ hart und biegesteif ist. Ein härteres Kunststoffmaterial wirkt daher besser als ein weiches Kunststoffmaterial, das leicht nachgibt.The resilient locking tab 21 is formed integrally with the hull. In this respect, the elastic properties of the hull are exploited. It is beneficial for the locking effect of the resilient locking tab 21 when the plastic material of the hull is relatively hard and rigid. A harder plastic material therefore works better than a soft plastic material that easily yields.

Die federnde Rastlasche 21 steht von dem Hakenrand 8 schräg nach unten ab. Wenn das Paneel 1 mit seiner Unterseite 10 auf einem Untergrund (nicht dargestellt) liegt, zeigt das freie Ende der federnden Rastlasche 21 in Richtung des Untergrunds. Die federnde Rastlasche 21 weist rumpffern eine Gleitfläche 23 auf, die während der Fügebewegung mit dem Arretierhaken 6 in Kontakt kommt und so ein Einfedern der Rastlasche 21 erzeugt. Durch das Einfedern wird die Rastlasche 21 näher an den Hakenrand 8 beziehungsweise näher zum Rumpf des Paneels 1 heranbewegt. Dabei wird die federnde Rastlasche 21 elastisch gespannt und gibt den vertikalen Fügeweg frei, damit der Arretierhaken 6 weiter abgesenkt werden kann. Der Arretierhaken 6 kann dann weiter in den Aufnahmehaken 5 eingefügt werden, bis sich beide Paneele 1 und 2 in einer Ebene befinden. Zwischen der federnden Rastlasche 21 und dem Hakenrand 8 ist ein Freiraum 24 vorgesehen, in den die Rastlasche 21 elastisch einfedern kann. Die elastische Vorspannung der Rastlasche 21 ermöglicht es der Rastlasche, in Richtung ihrer neutralen Position zurückzufedern, wenn sich Platz dafür bietet. Platz bietet sich dann, wenn die Rastlasche 21 während der Fügebewegung in den Bereich der Rastausnehmung 22 des Arretierhakens 6 gelangt.The resilient latching tab 21 projects obliquely downwards from the hook edge 8. If the panel 1 lies with its underside 10 on a substrate (not shown), the free end of the resilient locking tab 21 points in the direction of the ground. The resilient latching lug 21 has a sliding surface 23, which comes into contact with the locking hook 6 during the joining movement and thus produces a compression of the latching lug 21. By the compression, the locking tab 21 is moved closer to the hook edge 8 or closer to the hull of the panel 1. In this case, the resilient latching tab 21 is stretched elastically and releases the vertical Fügeweg so that the locking hook 6 can be further lowered. The locking hook 6 can then be inserted further into the receiving hook 5 until both panels 1 and 2 are in one plane. Between the resilient latching tab 21 and the hook edge 8, a free space 24 is provided, in which the latching tab 21 can deflect elastically. The elastic bias of the latching tab 21 allows the latching tab to spring back toward its neutral position when there is room for it. Space offers itself when the locking tab 21 passes during the joining movement in the region of the recess 22 of the locking hook 6.

Die Rastausnehmung 22 weist eine Rastkontaktfläche 25 auf, welche durch Kontakt mit der federnden Rastlasche 21 eine vertikal Arretierung verbundener Paneele bewirkt, dass heißt senkrecht zur Paneelebene.The latching recess 22 has a latching contact surface 25, which causes a vertical locking connected panels by contact with the resilient latching tab 21, that is perpendicular to the panel plane.

Die Rastkontaktfläche 25 ist so gestaltet, dass sie eine Anschlagschräge für das freie Ende der federnden Rastlasche 21 bildet. Die Anschlagschräge 26 ist so gestaltet, dass die gespannte federnde Rastlasche 21, wenn sie in Richtung ihrer neutralen Position zurückfedert, gegen diese Anschlagschräge 26 stößt, bevor sie ihre neutrale Position erreicht. So bleibt stets ein Rest Vorspannung in der Rastlasche 21 erhalten, wodurch eine sichere Arretierung gewährleistet ist.The latching contact surface 25 is designed so that it forms a stop bevel for the free end of the resilient latching tab 21. The stop bevel 26 is designed so that the tensioned resilient locking tab 21, when springing back in the direction of its neutral position, abuts against this stop bevel 26 before it reaches its neutral position. Thus, a residual bias in the locking tab 21 is always obtained, whereby a secure locking is ensured.

Ein bevorzugtes Ausführungsbeispiel eines viereckigen Paneels ist in Fig. 3 zu sehen, welche ausschnittsweise die Herstellung eines Fußbodenbelags aus erfindungsgemäßen Paneelen darstellt. Bei den verwendeten Paneelen handelt es sich um ein Ausführungsbeispiel mit einem ersten Kantenpaar, das komplementäre Hakenprofile H aufweist, sowie mit einem zweiten Kantenpaar, welches mit komplementären formschlüssigen Schwenkprofilen S versehen ist. Die Schwenkprofile S dienen dazu, Paneele unterschiedlicher Paneelreihen miteinander zu verbinden. Die Hakenprofile H dienen bei diesem Ausführungsbeispiel dazu, Paneele derselben Paneelreihe miteinander zu verbinden. Die Hakenprofile H des ersten Kantenpaares können so ausgebildet sein, wie in dem Ausführungsbeispiel der Figuren 1a bis 1d. Alternativ können die Hakenprofile H des ersten Kantenpaares dem Ausführungsbeispiel gemäß den Figuren 2a bis 2d entsprechen.A preferred embodiment of a quadrangular panel is in Fig. 3 to see which fragmentary represents the production of a floor covering of panels according to the invention. In the panels used is an embodiment with a first edge pair having complementary hook profiles H, and with a second edge pair, which is provided with complementary form-fitting pivoting profiles S. The swivel profiles S are used to connect panels of different panel rows together. The hook profiles H serve in this embodiment to connect panels of the same row of panels together. The hook profiles H of the first edge pair may be formed as in the embodiment of FIGS. 1a to 1d , Alternatively, the hook profiles H of the first edge pair of the embodiment according to the FIGS. 2a to 2d correspond.

Fig. 3 zeigt in der vordersten Paneelreihe III ein neues Paneel 27, das sowohl mit der vorherigen Paneelreihe II als auch mit dem benachbarten Paneel 28 derselben Paneelreihe III verriegelt werden soll. Das neue Paneel 27 ist schräg in Bezug auf die Ebene der verlegten Paneele angesetzt und mit einem seiner Schwenkprofile S an die vordere Paneelreihe II angesetzt. Es wird anschließend durch Herabschwenken in die Ebene der verlegten Paneele mit der vorherigen Paneelreihe Fig. 3 shows in the front row of panels III a new panel 27 to be locked with both the previous panel row II and with the adjacent panel 28 of the same panel row III. The new panel 27 is attached obliquely with respect to the plane of the laid panels and with one of its pivoting profiles S to the front row of panels II stated. It is then lowered into the plane of the laid panels with the previous row of panels

II verriegelt. Gleichzeitig verriegelt dabei auch das Hakenprofil (Arretierhaken 6) des neuen Paneels 27 mit dem Hakenprofil (Aufnahmehaken 5) des Paneels 28 derselben Paneelreihe III. Der Arretierhaken 6 wird, während das neue Paneel 27 in die Ebene der verlegten Paneele herabschwenkt, gleichzeitig in einer scherenartigen Fügebewegung mit dem Aufnahmehaken 5 in Eingriff gebracht. Der Aufnahmehaken 5 weist einen Biegestegs auf, dessen elastische Biegung Schritt für Schritt vollzogen wird, je weiter der Arretierhaken 6 in Richtung des Aufnahmehakens 5 bewegt wird, beziehungsweise je weiter der Arretierabsatz des Arretierhaken 6 in die Aufnahmeaussparung des Aufnahmehakens 5 eingefügt wird.II locked. At the same time, the hook profile (locking hook 6) of the new panel 27 locks with the hook profile (receiving hook 5) of the panel 28 of the same panel row III. The locking hook 6, while the new panel 27 pivots down into the plane of the laid panels, simultaneously brought in a scissor-like joining movement with the receiving hooks 5 in engagement. The receiving hook 5 has a bending web whose elastic bending is completed step by step, the further the locking hook 6 is moved in the direction of the receiving hook 5, or the further the locking shoulder of the locking hook 6 is inserted into the receiving recess of the receiving hook 5.

Für das zweite Kantenpaar kommen als komplementäre Schwenkprofile S alle bekannten formschlüssigen Profile in Frage, die sich durch schräges Ansetzen eines neuen Paneels an eine vorherige Paneelreihe und anschließendes Herabschwenken des neuen Paneels in die Ebene der verlegten Paneele formschlüssig verbinden lassen. Ein Ausführungsbeispiel für ein derartiges Schwenkprofil S ist in Fig. 4 gezeigt.For the second pair of edges come as a complementary pivoting profiles S all known form-fitting profiles in question, which can be positively connect by oblique attachment of a new panel to a previous row of panels and then pivoting down the new panel in the plane of the laid panels. An embodiment of such a pivot profile S is in Fig. 4 shown.

Die komplementären Schwenkprofile S gemäß Fig. 4 umfassen ein Nutprofil 29 und ein Federprofil 30. Das Nutprofil 29 weist eine obere Nutwand 29a auf, die kürzer ist als die untere Nutwand 29b. Die untere Nutwand 29b ist außerdem mit einer hinterschnittenen Ausnehmung 29c für das Federprofil 30 versehen. Die Ausnehmung 29c weist außerdem eine Horizontalverriegelungsfläche 29d auf. Das Federprofil 30 ist mit einer Federoberseite 30a versehen, die im Wesentlichen parallel zur Oberseite 7 des neuen Paneels 27 angeordnet ist. Die Federunterseite 30b weist einen Hinterschnitt 30c auf und eine Horizontalverriegelungsfläche 30d, die mit der Horizontalverriegelungsfläche 29d der unteren Nutwand 29b zusammenwirkt. Die Schrägstellung des neuen Paneels 27 gemäß Fig. 3 ist in Fig. 4 kenntlich gemacht durch die gestrichelt dargestellte Position des Federprofil 30'. Die Federunterseite 30b wird auf die längere unter Nutwand 29b aufgelegt. Das neue Paneel 27 wird mit die Federspitze voran in das Nutprofil bewegt und das neue Paneel 27 anschließend in die Ebene des/der liegenden Paneele herabgeschwenkt.The complementary pivoting profiles S according to Fig. 4 include a groove profile 29 and a spring profile 30. The groove profile 29 has an upper groove wall 29a, which is shorter than the lower groove wall 29b. The lower groove wall 29 b is also provided with an undercut recess 29 c for the spring profile 30. The recess 29c also has a horizontal locking surface 29d. The spring profile 30 is provided with a spring upper side 30a, which is arranged substantially parallel to the upper side 7 of the new panel 27. The spring lower side 30b has an undercut 30c and a horizontal locking surface 30d which cooperates with the horizontal locking surface 29d of the lower groove wall 29b. The inclination of the new panel 27 according to Fig. 3 is in Fig. 4 indicated by the dashed lines shown position of the spring profile 30 '. The lower spring side 30b is placed on the longer under groove wall 29b. The new panel 27 is moved forward with the nib in the groove profile, and the new panel 27 is then pivoted down into the plane of the underlying panel (s).
