Description

Die vorliegende Erfindung betrifft eine Platte, insbesondere eine Bodenplatte als Kombi-Barfußdiele, die sich sowohl innerhalb als auch außerhalb eines Gebäudes verlegen lässt, gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a plate, in particular a base plate as a combination barefoot board, which can be installed both inside and outside a building, according to the preamble of claim 1.

Es gibt Bodenplatten, die aus einem Vollprofil aus Holz oder einem verpressten Holzwerkstoff hergestellt sind, wobei an der Oberseite Profilierungen zur Erhöhung der Rutschfestigkeit vorgesehen sein können. Zur Verriegelung dieser Platten weisen diese an ihren Längskanten jeweils eine Nut auf, in die ein Verbindungselement mit Federn eingefügt werden kann, dass dann an dem Boden festgelegt wird. Der Einsatz von Platten aus Holz besitzt den Nachteil, dass diese relativ schnell einem Alterungsprozess unterliegen und nach mehreren Jahren ausgewechselt werden müssen. Gerade für Terrassen oder Balkone müssen Platten aus Holz häufig imprägniert werden, um die Lebensdauer zu verlängern.There are floor panels, which are made of a solid profile of wood or a compressed wood material, which may be provided on the upper side profiles to increase the slip resistance. To lock these plates, these have at their longitudinal edges in each case a groove into which a connecting element can be inserted with springs, which is then fixed to the ground. The use of wood panels has the disadvantage that they are relatively quickly subject to aging and must be replaced after several years. Especially for terraces or balconies, wood panels often need to be impregnated to extend the life.

Ferner gibt es für den Innenbereich mit einer Laminatschicht versehene Platten, die eine beschichtete Trägerschicht aus verpresstem Leim und Späne aufweisen. Bei der Herstellung werden die Platten abgetrennt und an ihren Kanten durch Fräsen profiliert, um diese beim Verlegen verriegeln zu können. Die Herstellung solcher gefrästen Profile ist relativ aufwendig. Ferner sind diese Platten nur schlecht für den Außenbereich einsetzbar, da sie nicht witterungsbeständig sind.Further, there are laminated panels provided with a laminated layer for the interior, which have a coated carrier layer of pressed glue and chips. In the production of the plates are separated and profiled by milling at their edges to lock them during installation can. The production of such Milled profiles is relatively expensive. Furthermore, these plates are only bad for outdoor use because they are not weather resistant.

Aus US 2002/059766 A ist eine Platte der eingangs genannten Gattung bekannt.Out US 2002/059766 A a plate of the type mentioned is known.

Es ist Aufgabe der vorliegenden Erfindung eine Platte, insbesondere eine Bodenplatte, zu schaffen, die einfach zu verlegen ist eine hohe Witterungsbeständigkeit sowie eine hohe Rutschfestigkeit besitzt.It is an object of the present invention to provide a plate, in particular a bottom plate, which is easy to install has a high weather resistance and high slip resistance.

Diese Aufgabe wird mit einer Platte mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with a plate having the features of claim 1.

Die Platte besteht erfindungsgemäß aus einem im Extrusionsverfahren hergestellten Körper aus einer Mischung aus Naturstoffen, wie Holzfasern, Holzspäne, Stroh, Heu, Reisschalen oder dergleichen, und Kunststoff, wobei die Platte an gegenüberliegenden Längsseiten ein integral ausgebildetes Verriegelungssystem aus Nut und/oder Feder aufweist. Die Platte lässt sich somit in einem Herstellungsschritt durch Extrudieren fertigen und muss nicht in mehreren Schritten nachbearbeitet werden, um ein Verriegelungsprofil zu fräsen oder die Oberfläche dekorativ zu beschichten. Denn im Extrusionsverfahren kann die Platte in einem Arbeitsgang in der gewünschten Form hergestellt werden. Die Platte ist gleich verlegefertig ausgebildet und weist eine begehbare Oberfläche auf. Durch den Einsatz von einer Mischung aus Naturstoffen und Kunststoff ist die Platte extrem witterungsbeständig, da keine Feuchtigkeit in die Platte eindringen kann.The plate according to the invention consists of a body produced by extrusion of a mixture of natural materials such as wood fibers, wood chips, straw, hay, rice husks or the like, and plastic, wherein the plate has on opposite longitudinal sides an integrally formed locking system of groove and / or spring. The plate can thus be produced in one production step by extrusion and does not need to be post-processed in several steps in order to mill a locking profile or decorative coating the surface. Because in the extrusion process, the plate can be produced in one operation in the desired shape. The plate is designed ready for laying and has a walk-on surface. Through the use of a mixture of natural materials and plastic, the plate is extremely weather-resistant, since no moisture can penetrate into the plate.

Gemäß der Erfindung ist an der Oberseite eine rutschhemmende Profilierung einextrudiert. Die rutschhemmende Profilierung kann beispielsweise aus mehreren beabstandet zueinander angeordneten Rillen bestehen, die einen verbesserten Halt beim Betreten geben und auch ein Abströmen von Regenwasser zur Seite hin ermöglichen. Zusätzlich oder alternativ kann die Oberfläche gebürstet werden. Bei einem Bürsten mittels einer Stahlbürste entstehen kleine Längsrillen, die eine besonders rutschhemmende Oberfläche ausbilden, obwohl eine Splitterbildung nicht erfolgt, wie dies bei einem reinen Holzwerkstoff der Fall wäre.According to the invention, an anti-slip profiling is extruded on the upper side. The slip-resistant profiling can for example consist of several spaced-apart grooves, which give an improved grip when entering and also allow rainwater to escape to the side. Additionally or alternatively, the surface may be brushed. When brushing by means of a steel brush small longitudinal grooves, which form a particularly slip-resistant surface, although a splintering does not occur, as would be the case with a pure wood material.

Gemäß der Erfindung ist an der Unterseite der Platte ebenfalls eine begehbare Oberfläche ausgebildet, die eine anders gestaltete Profilierung als die Oberseite aufweist. Dann kann die Platte wahlweise mit der Ober- oder Unterseite nach oben verlegt werden, je nach Geschmack des Verwenders, ohne dass zwei getrennt Platten hergestellt und gelagert werden müssen.According to the invention, a walk-on surface is also formed on the underside of the plate, which has a differently shaped profiling than the top. Then The plate can optionally be laid with the top or bottom up, depending on the taste of the user, without two separate plates must be made and stored.

Um das Gewicht der Platte gering zu halten und nur relativ wenig Material für eine Bodenplatte zu verwenden, sind an der Unterseite vorzugsweise mehrere leistenförmige Aussparungen vorgesehen. Dadurch wird bei vorgegebener Dicke einer Platte der Materialverbrauch gesenkt und zusätzlich lässt sich die Platte verschiebesicher auf einem Boden verlegen, da die abwechselnde Anordnung von Aussparungen und hervorstehenden Stegen einen erhöhten Halt geben. Die Aussparungen besitzen vorzugsweise eine Tiefe zwischen 20 und 60 %, insbesondere 30 bis 50 % der Dicke der Platte, sodass die Platte noch eine ausreichende Trittfestigkeit besitzt. Alternativ ist es möglich, die Platte als Hohlprofil mit mehreren Hohlkammern auszubilden, so dass bezogen auf die Festigkeit der Platte der Materialverbrauch und das Gewicht vergleichsweise gering sind.In order to keep the weight of the plate low and to use only a relatively small amount of material for a bottom plate, preferably several strip-shaped recesses are provided on the underside. As a result, the material consumption is reduced for a given thickness of a plate and in addition, the plate can move safely on a floor, as the alternating arrangement of recesses and protruding webs give increased support. The recesses preferably have a depth between 20 and 60%, in particular 30 to 50% of the thickness of the plate, so that the plate still has sufficient resistance to impact. Alternatively, it is possible to form the plate as a hollow profile with a plurality of hollow chambers, so that based on the strength of the plate, the material consumption and weight are relatively low.

Vorzugsweise enthält die Platte einen eingefärbten Kunststoff, der witterungsbeständig ist und im wesentlichen die Farbe beibehält. Dadurch kann die Platte gerade für Terrassen oder Balkone eingesetzt werden und es lässt sich mit der Zugabe von geeigneten Farbstoffen eine dekorativ ansprechende Platte bereitstellen.Preferably, the plate contains a colored plastic which is weather resistant and substantially retains the color. As a result, the plate can be used straight for terraces or balconies and it can be provided with the addition of suitable dyes a decorative appealing plate.

Zur Festlegung der Platten können an zwei gegenüberliegenden Längskanten jeweils eine Nut zur Einfügung einer Feder eines Verbindungselementes vorgesehen sein. Die Nut kann dabei keilförmig und zu einer horizontalen Ebene symmetrisch ausgebildet sein, damit mit den gleichen Verbindungselementen die Platte mit der Oberseite oder Unterseite nach oben gerichtet montiert werden kann. Alternativ ist es möglich, an einer Längskante eine hinterschnittene Nut und an einer gegenüberliegenden Längskante ein in die Nut einfügbares Federprofil auszubilden, die dann ineinander geschwenkt werden können, um eine dauerhafte Verriegelung der Platten zu erreichen.To fix the plates, a groove for inserting a spring of a connecting element can be provided on two opposite longitudinal edges. The groove may be wedge-shaped and formed symmetrically to a horizontal plane, so that with the same connecting elements, the plate with the top or bottom can be mounted directed upwards. Alternatively, it is possible to form at one longitudinal edge an undercut groove and at an opposite longitudinal edge an insertable into the groove spring profile, which can then be pivoted into each other to achieve a permanent locking of the plates.

Eine Platte 1 umfasst einen Körper 2, der aus einer Mischung aus Naturstoffen, wie Holzfasern, Holzspäne, Stroh, Heu, Reisschalen oder dergleichen und Kunststoff, vorzugsweise Polypropylen im Extrusionsverfahren hergestellt ist. Diese Naturstoffe sind äußerst kostengünstig zu Beschaffen und können neben Polypropylen auch mit einem anderen Polymer verarbeitet werden. Die Mischung aus Kunststoff und Naturstoffen wird erhitzt und durch einen Extruder gedrückt, der der Platte 1 die entgültige Form gibt. Der Anteil an Polypropylen kann je nach Festigkeitsanforderungen zwischen 20 und 40 % liegen. Für eine stärkere Bindung kann die Mischung auch einen Anteil an Zement aufweisen.A plate 1 comprises a body 2 which is made of a mixture of natural materials such as wood fibers, wood chips, straw, hay, rice husks or the like and plastic, preferably polypropylene by extrusion. These natural products are extremely inexpensive to procure and can be processed in addition to polypropylene with another polymer. The mixture of plastic and natural materials is heated and forced through an extruder, which gives the disk 1 the final form. The proportion of polypropylene can be between 20 and 40%, depending on the strength requirements. For a stronger bond, the mixture may also have a proportion of cement.

Die Platte 1 ist in der Draufsicht rechteckig ausgebildet und weist eine wesentlich größere Länge als Breite auf. An der Oberfläche sind in Längsrichtung verlaufende Rillen 3 ausgespart, zwischen denen leistenförmige Vorsprünge 4 angeordnet sind. Durch die Rillen 3 wird die Rutschfestigkeit an der Oberfläche erhöht, wobei sich die Rillen 3 nur über einen geringfügigen Teil der Höhe der Platte 1 erstrecken. Ferner ist die Oberfläche mittels gebürstet und daher mit feinen Längsrillen versehen.The plate 1 is rectangular in plan view and has a much greater length than width. On the surface longitudinally extending grooves 3 are recessed, between which strip-shaped projections 4 are arranged. By the grooves 3, the slip resistance is increased at the surface, wherein the grooves 3 extend over only a small part of the height of the plate 1. Furthermore, the surface is brushed and therefore provided with fine longitudinal grooves.

An der gegenüberliegenden Unterseite ist ebenfalls eine begehbare Fläche mit Einschnitten 6 und Rippen 5 ausgebildet, es ist also eine zu der Oberseite abgewandelte Profilierung ausgebildet, die im Extrusionsverfahren ohne Nachbehandlung herstellbar ist. Dadurch kann der Verwender frei entscheiden, welche der beiden profilierten Flächen sichtbar sein soll. Die Platte 1 ist mit beiden Seiten nach oben verlegbar und aufgrund des Materials splitterfrei, so dass sie sich als Kombi-Barfußdiele einsetzen lässt.On the opposite bottom is also a walk-surface with cuts 6 and ribs 5 is formed, so it is a modified to the top Profiling formed that can be produced in the extrusion process without aftertreatment. This allows the user to freely decide which of the two profiled surfaces should be visible. The plate 1 can be laid with both sides upwards and, due to the material, shatterproof, so that it can be used as a combi barefoot board.

Die Platte 1 ist als Hohlprofil ausgebildet und umfasst mehrere im Querschnitt rechteckförmige Hohlkammern 8 die über Stege 7 voneinander beabstandet sind. Die Stege 7 verbinden die Oberseite mit der Unterseite und sorgen für eine ausreichende Trittfestigkeit der Platte 1.The plate 1 is formed as a hollow profile and comprises a plurality of rectangular cross-section hollow chambers 8 which are spaced apart by webs 7. The webs 7 connect the top with the bottom and ensure sufficient resistance to impact of the plate. 1

An gegenüberliegenden Längskanten der Platte 1 ist jeweils eine zur Höhe der Platte 1 etwa mittige Nut 9 vorgesehen, die keilförmig verlaufende Wände 10 aufweist und zu einer horizontalen Ebene symmetrisch ist.At opposite longitudinal edges of the plate 1 is provided in each case one to the height of the plate 1 approximately central groove 9, which has wedge-shaped walls 10 and is symmetrical to a horizontal plane.

In Figuren 2a) und 2b) ist die Platte 1 über ein Verriegelungssystem jeweils im montierten Zustand gezeigt, wobei in Figur 2a) die Rillen 3 nach oben angeordnet sind und in Figur 2) die Rippen 5 und Einschnitte 6 nach oben angeordnet sind. In die Nut 9 der Platte 1 ist eine keilförmige Feder 13 mit entsprechenden schrägen Wänden 12 eines Verbindungselementes 11 eingefügt. Das Verbindungselement 11 weist an gegenüberliegenden Seiten Federn 13 auf, die dann in die Nuten 9 zweier benachbarter Platten 1 eingefügt sind.In FIGS. 2a) and 2b ), the plate 1 is shown via a locking system respectively in the assembled state, wherein in FIG. 2a ) the grooves 3 are arranged upwards and in FIG. 2 ) the ribs 5 and 6 cuts are arranged upwards. In the groove 9 of the plate 1, a wedge-shaped spring 13 is inserted with corresponding oblique walls 12 of a connecting element 11. The connecting element 11 has on opposite sides springs 13, which are then inserted into the grooves 9 of two adjacent plates 1.

Das Verbindungselement 11 ist an der Unterseite mit einem leistenförmigen Vorsprung 14 ausgebildet, der sich etwa bis zu dem Boden erstreckt. Das Verbindungselement 11 kann von oben durch bekannte Befestigungsmittel, wie Schrauben, Klammern oder andere Befestigungsmittel mit einem unter den Platten 1 angeordneten Bodengerüst verbunden werden, wobei durch die keilförmige Ausgestaltung der Nuten 9 und der Federn 13 ein Festklemmen der Platten 1 erreicht wird. Das Verbindungselement 11 kann dabei wie die Platten 1 aus dem oben genannten extrudierten Material oder einem anderen Material hergestellt sein.The connecting element 11 is formed on the underside with a strip-shaped projection 14 which extends approximately to the bottom. The connecting element 11 can be connected from above by known fastening means, such as screws, clamps or other fastening means with a arranged under the plates 1 floor scaffold, with the wedge-shaped configuration of the grooves 9 and the springs 13, a clamping of the plates 1 is achieved.

In Figur 3 ist eine modifizierte Ausführungsform einer erfindungsgemäßen Platte 1' gezeigt. An der Oberseite ist die Platte 1 wieder mit Rillen 3' und Vorsprüngen 4' versehen. Diese Platte 1' ist jedoch nicht als Hohlprofil ausgebildet sondern weist an der Unterseite leistenförmige Aussparungen 6' vorgesehen, die von stützenden Fußleisten 5' umgeben sind. Die Dicke der Platte 1 ergibt sich aus der Strecke zwischen den Fußleisten 5' und der Oberseite der Vorsprünge 4. Durch die Aussparungen 6' wird bezogen auf die Dicke der Platte 1 der Materialverbrauch und das Gewicht verringert, wobei die Dicke der Platte 1 in dem Bereich des Aussparungen 6' immer noch eine ausreichende Trittfestigkeit gewährleistet. Die Aussparungen 6' erstrecken sich über etwa 40 % der Dicke der Platte 1.In FIG. 3 a modified embodiment of a plate 1 'according to the invention is shown. At the top, the plate 1 is again with grooves 3 'and projections 4 'provided. However, this plate 1 'is not formed as a hollow profile but has at the bottom strip-shaped recesses 6' are provided, which are surrounded by supporting baseboards 5 '. The thickness of the plate 1 results from the distance between the skirting 5 'and the top of the projections 4. By the recesses 6' is based on the thickness of the plate 1, the material consumption and weight reduced, the thickness of the plate 1 in the Area of the recesses 6 'still ensures sufficient resistance to impact. The recesses 6 'extend over approximately 40% of the thickness of the plate first

In Figur 4 ist die Platte 1 mittels einer Befestigungsklammer 20 am Boden festgelegt. Die metallische Befestigungsklammer 20 weist nach oben herausragende Vorsprünge 21 und 22 auf, die jeweils zu einer Seite hin abgewinkelt sind. Der winklige Teil liegt dabei an einer schrägen unteren Wand 10 der Nut 9 einer Platte 1 an, so dass zwei benachbarte Platten 1 klemmend am Boden festlegbar sind. Dabei wird die Befestigungsklammer 20 mit einem ebenen Bodenabschnitt 23 an einer unterer Auflage festgeschraubt, so dass die Platten 1 dann in die entsprechenden Vorsprünge 21 und 22 mit ihren Nuten 9 eingeschoben werden können.In FIG. 4 the plate 1 is fixed by means of a mounting bracket 20 at the bottom. The metallic mounting bracket 20 has upwardly projecting projections 21 and 22 which are each angled toward one side. The angled part rests against an oblique lower wall 10 of the groove 9 of a plate 1, so that two adjacent plates 1 can be clamped to the ground. In this case, the mounting bracket 20 is screwed with a flat bottom portion 23 to a lower support, so that the plates 1 can then be inserted into the corresponding projections 21 and 22 with their grooves 9.

In Figur 5 ist die Befestigungsklammer 20 aus Edelstahl im Detail gezeigt. Die Vorsprünge 21 und 22 sind in eine Richtung längs zu der Nut 9 der Platten 1 versetzt angeordnet und weisen mit ihrem winkligen Abschnitt in entgegengesetzte Richtungen. Die Vorsprünge lassen sich beispielsweise durch Stanzen und Biegen herstellen. Hierdurch sind in dem Bodenabschnitt 23 Aussparungen 24 und 25 ausgebildet. Benachbart zu den Vorsprüngen 21 und 22 sind Öffnungen 26 für Schrauben vorgesehen.In FIG. 5 the mounting bracket 20 is shown in detail from stainless steel. The projections 21 and 22 are offset in a direction along the groove 9 of the plates 1 and have with their angled portion in opposite directions. The projections can be produced for example by punching and bending. As a result, recesses 24 and 25 are formed in the bottom portion 23. Adjacent to the projections 21 and 22 openings 26 are provided for screws.

Die dargestellte Erfindung ist nicht auf die gezeigten Ausführungsbeispiele beschränkt. Statt des gezeigten Verriegelungssystems können auch andere Verriegelungssysteme eingesetzt werden, wobei die Platten aus extrudiertem Material jeweils einen Bestandteil des Verriegelungssystems aufweisen, nämlich eine Nut oder eine Feder .The illustrated invention is not limited to the embodiments shown. Instead of the locking system shown, other locking systems can be used, wherein the plates of extruded material each have a part of the locking system, namely a groove or a spring.
