Description

Die Erfindung geht aus von einem Bodenbelagsgitter, insbesondere zur Bildung eines Fallschutzbelages, nach den Oberbegriffen der AnsprĂĽche 1 und 8.The invention is based on a floor covering grid, in particular for the formation of a fall protection covering, according to the preambles of claims 1 and 8.

Bodenbeläge, insbesondere Fallschutzbeläge, sind an sich bekannt. Für solche Beläge sind weiterhin Belagselemente oder -platten bekannt, welche insbesondere eine Fallschutzfunktion aufweisen, d.h. dass der Belag gegenüber einer senkrecht auf die Oberfläche des Belags wirkenden Kraft energieabsorbierend wirkt, so dass eine fallende Person - etwa ein Kind auf einem öffentlichen oder privaten Kinderspielplatz - beim Auftreffen auf den Belag vergleichsweise geringe Beschleunigungskräfte erfährt. Die Verletzungsgefahr sinkt mit einer sinkenden Beschleunigungskraft. Nachteilig an den bekannten Belägen ist, dass diese die Installation eines kostenintensiven Unterbaus benötigen und/oder einen vegetativen, natürlichen Boden unter dem Belag nahezu vollständig verdecken. Ferner weisen bekannte Fallschutzbeläge biegsame Brückenteile auf, wobei durch ein Durchbiegen derselben die energieabsorbierende Wirkung im Falle einer Krafteinwirkung erzielt wird. Aufgrund dieser permanenten Biegebelastung der Brückenteile verringert sich die Lebensdauer des Belags erheblich.Floor coverings, in particular fall protection coverings, are known per se. For such coverings, there are also known covering elements or plates, which in particular have a fall protection function, i. in that the covering acts to absorb energy relative to a force acting perpendicularly on the surface of the covering, so that a falling person - such as a child on a public or private children's playground - experiences comparatively low acceleration forces when hitting the covering. The risk of injury decreases with a decreasing acceleration force. A disadvantage of the known coverings is that they require the installation of a costly substructure and / or cover a vegetative, natural soil under the covering almost completely. Furthermore, known fall arresting pads on flexible bridge parts, wherein by a bending of the same the energy absorbing effect is achieved in the event of a force. Due to this permanent bending load on the bridge parts, the service life of the lining is reduced considerably.

Aus dem DE 85 27 295 U1 ist ein Vegetationsgitterstein bekannt, welcher aus einer Mehrzahl von stegförmigen ersten und zweitenBodenbelagselementen zusammengesetzt werden kann. Die einzelnen Bodenbelagselemente weisen in Rasterabständen angeordnete Einsteckschlitze auf, die sich über die halbe Höhe des Bodenbelagselements erstrecken. Werden die ersten und zweiten Bodenbelagselemente senkrecht zueinander und sich kreuzend angeordnet, können sie mittels ihrer Einsteckschlitze vollständig ineinander eingreifen. Hierdurch können die ersten und zweiten Bodenbelagselemente zum Vegetationsgitterstein zusammengefügt werden. Der Vegetationsgitterstein der DE8527295U1 offenbart alle Merkmale der einleitenden Teile der Produktansprüche 1 und 8.From the DE 85 27 295 U1 For example, there is known a vegetation lattice which may be composed of a plurality of ridge-shaped first and second flooring elements. The individual floor covering elements have insertion slots arranged at grid intervals, which extend over half the height of the floor covering element. If the first and second floor covering elements are arranged perpendicular to one another and intersecting, they can completely engage in one another by means of their insertion slots. This allows the first and second flooring elements are joined together to form the vegetation grid stone. The vegetation lattice of the DE8527295U1 discloses all features of the introductory parts of the claims 1 and 8.

Der Erfindung liegt daher die Aufgabe zugrunde, ein insbesondere aus Bodenbelagselementen gebildetes Bodenbelagsgitters und eine Anordnung von Bodenbelagsgittern bereitzustellen, welches die Nachteile des Standes der Technik nicht aufweist und gleichzeitig kostengĂĽnstig herstellbar, sowie durch ein variables Stecksystem universell einsetzbar ist.The invention is therefore based on the object to provide a floor covering grid formed in particular from flooring elements and an array of floor covering grids, which does not have the disadvantages of the prior art and at the same time inexpensive to produce, and is universally applicable by a variable plug-in system.

Zur Lösung dieser Aufgabe kann ein Bodenbelagselement zur Bildung eines Bodenbelagsgitters genutzt werden, welches einen eine erste Seite bildenden ersten Teilbereich und einen eine zweite Seite bildenden zweiten Teilbereich aufweist, wobei das Bodenbelagselement eine zur ersten und zur zweiten Seite parallele Haupterstreckungsrichtung aufweist und wobei der erste Teilbereich
wenigstens eine den Verlauf der ersten Seite unterbrechende Aussparung aufweist und der zweite Teilbereich einen in einer zur Haupterstreckungsrichtung senkrechten Richtung die Aussparung überlappenden dritten Teilbereich aufweist. Hierdurch ist es vorteilhaft möglich durch Zusammenfügen einer Mehrzahl von derartigen Bodenbelagselementen in einfacher und kostengünstiger Weise ein Bodenbelagsgitter zu bilden, wobei je nach Anordnung eines Bodenbelagselements sowohl die erste, als auch die zweite Seite eines Bodenbelagselements die Sichtseite des Bodenbelagsgitters darstellt. Eine Variation der Höhe des Bodenbelagselements parallel zur senkrechten Richtung erlaubt eine Variation der Fallschutzfähigkeit des Bodenbelags, da die Menge bzw. Dicke des energieabsorbierenden Material bezüglich einer senkrechten Kraftwirkung auf den Belag variiert. Ferner sind die Fallschutzfähigkeit, die optische Wirkung und/oder die Wasserdurchlässigkeit des Bodenbelags durch eine Anpassung des Abstands zwischen den Aussparungen in der Haupterstreckungsrichtung einstellbar, wobei bevorzugt ein Bodenbelagselement mit einer Mehrzahl von Aussparungen, welche jeweils einen konstantem Abstand voneinander aufweisen, vorgesehen ist. Die Anzahl der Aussparungen eines Bodenbelagselements ist frei wählbar, beispielsweise sind wenigstens zwei, wenigstens 6 oder wenigstens 10 Aussparungen, vorzugsweise 13 oder 14 Aussparungen, in einem Bodenbelagselement vorgesehen.To achieve this object, a floor covering element can be used to form a floor covering grid, which has a first partial area forming a first side and a second partial area forming a second side, wherein the floor covering element has a main extension direction parallel to the first and second side and wherein the first partial area
has at least one the course of the first side interrupting recess and the second portion has a in a direction perpendicular to the main extension direction of the recess overlapping third portion. This makes it possible advantageously by joining a plurality of such flooring elements in a simple and cost-effective manner to form a floor covering grid, depending on the arrangement of a floor covering both the first, and the second side of a floor covering element represents the visible side of the floor covering grid. Variation of the height of the flooring element parallel to the vertical direction allows for variation of the fall protection capability of the flooring as the amount or thickness of the energy absorbing material varies with respect to a vertical force action on the flooring. Furthermore, the fall protection capability, the visual effect and / or the water permeability of the floor covering are adjustable by adjusting the distance between the recesses in the main direction of extension, wherein preferably a floor covering element is provided with a plurality of recesses, which each have a constant distance from each other. The Number of recesses of a floor covering element is arbitrary, for example, at least two, at least 6 or at least 10 recesses, preferably 13 or 14 recesses provided in a floor covering element.

Besonders bevorzugt ist, dass die Länge der Aussparung parallel zur Haupterstreckungsrichtung im Wesentlichen gleich der Breite des dritten Teilbereichs senkrecht zur Haupterstreckungsrichtung und zur senkrechten Richtung vorgesehen ist, wobei besonders bevorzugt das gesamte Bodenbelagselement die konstante Breite des dritten Teilbereichs aufweist. In vorteilhafter Weise wird somit eine formschlüssige Verbindung zwischen einer Mehrzahl von Bodenbelagselementen bei der Bildung eines Bodenbelagsgitters realisiert und somit die Stabilität, insbesondere die Verwindungssteifigkeit, des Bodenbelagsgitters erheblich erhöht. Weiterhin erlaubt die Variation der Breite des Bodenbelagselements eine weitere Anpassung der Fallschutzfähigkeit, der optischen Wirkung und/oder der Wasserdurchlässigkeit des Bodenbelags. Bevorzugt wird ein elastisches Material verwendet, so dass eine Kraftwirkung auf das Bodenbelagselement eine reversible Deformation desselben bewirkt, bspw. beim Fallen eines Kindes auf den Bodenbelag oder beim Betreten des Bodenbelags durch eine Person. Diese reversible Deformation des Bodenbelagselements ist zur Reduzierung einer Beschleunigungsspannung bspw. beim Auftreffen des fallenden Kindes vorgesehen, so dass das Bodenbelagselement insbesondere als Element eines Fallschutzbelages einsetzbar ist. Gleichzeitig weist das Material eine derartige Trittfestigkeit auf, dass eine Beschädigung oder irreversible Deformation des Bodenbelagselements, bspw. durch Brechen oder Reißen des Materials, beim Betreten durch Personen oder einer Mehrzahl von Personen verhindert wird. Das Bodenbelagselement ist insbesondere aus einem witterungsbeständigen Material, so dass das Bodenbelagselement im Außenbereich, d.h. im Freien, einsetzbar ist und den üblichen Umwelteinflüssen wie Temperaturschwankungen, Feuchtigkeit und Sonneneinstrahlung ohne Reduzierung der Fallschutzfähigkeit beispielsweise wenigstens über eine Mehrzahl von Jahren standhält, d.h. dass das Bodenbelagselement im Freien bevorzugt wenigstens eine übliche mittlere Langlebigkeit von bekannten Außenböden, insbesondere Kunststoffaußenböden, aufweist.It is particularly preferred that the length of the recess is provided parallel to the main extension direction substantially equal to the width of the third portion perpendicular to the main extension direction and to the vertical direction, wherein particularly preferably the entire floor covering element has the constant width of the third portion. Advantageously, thus, a positive connection between a plurality of flooring elements is realized in the formation of a floor covering grid and thus the stability, in particular the torsional rigidity, of the floor covering grid significantly increased. Furthermore, the variation of the width of the floor covering element allows a further adaptation of the fall protection capability, the optical effect and / or the water permeability of the floor covering. Preferably, an elastic material is used, so that a force acting on the flooring element causes a reversible deformation of the same, for example. When a child falls on the floor covering or when entering the floor by a person. This reversible deformation of the flooring element is provided for reducing an acceleration voltage, for example, when hitting the falling child, so that the floor covering element can be used in particular as an element of a fall protection covering. At the same time, the material has such an impact resistance that damage or irreversible deformation of the flooring element, for example, by breaking or tearing of the material when entering by persons or a plurality of persons is prevented. The flooring element is in particular made of a weather-resistant material, so that the flooring element in the outdoor area, ie outdoors, is used and the usual environmental influences such as temperature fluctuations, moisture and sunlight without reducing the fall protection, for example, at least over a plurality of years withstand, ie that the flooring element outdoors preferably at least a usual average longevity of known outdoor floors, in particular plastic outer floors has.

Besonders bevorzugt ist weiterhin, dass das Bodenbelagselements parallel zur Haupterstreckungsrichtung eine Gesamtlänge von 0,1 bis 20 Meter, bevorzugt 0,2 bis 10 Meter und besonders bevorzugt 0,25 bis 3 Meter, aufweist. Derartige Längeneinheiten des Bodenbelagselements gewährleisten eine vergleichsweise einfache Handhabe und begünstigen somit den Montagevorgang der Bodenbelagselemente. Ferner lassen sich Bodenbelagselemente derartiger Längen in kostengünstiger Weise transportieren.It is furthermore particularly preferred that the floor covering element has an overall length of 0.1 to 20 meters, preferably 0.2 to 10 meters and particularly preferably 0.25 to 3 meters, parallel to the main extension direction. Such units of length of the flooring element ensure a comparatively simple handle and thus favor the assembly process of the floor covering elements. Furthermore, floor covering elements of such lengths can be transported in a cost-effective manner.

Die derartigen Möglichkeiten der Anpassung der Fallschutzfähigkeit ist für die Verwendung des Bodenbelags an öffentlichen Plätzen, insbesondere mit Zugang für Kinder und insbesondere an Spielplätzen, von erheblicher Bedeutung, da die dort verbauten Fallschutzbeläge gemäß der europäischen Norm EN1177 einen besonders guten Fallwert aufweisen. Die Energieabsorptionsfähigkeit eines aus den erfindungsgemäßen Bodenbelagselementen aufgebauten Bodenbelagsgitters oder einer Anordnung von Bodenbelagsgittern wird mittels eines sogenannten HIC-Wertes (Head Injury Creation) gemessen, der insbesondere mit der Beschleunigung eines fallenden Körpers beim Auftreffen korreliert. Maßgebend ist hierbei nach der genannten Norm, dass die Fallhöhe bei einem HIC-Wert von 1000 möglichst groß ist. Dies ist mit dem erfindungsgemäßen Bodenbelagselement bzw. dem Bodenbelagsgitter und der Anordnung von Bodenbelagsgittern in einfacher und kostengünstiger Weise erzielbar, wobei die genannten Möglichkeiten der Fallschutzfähigkeitsanpassung je nach Anforderung an den Bodenbelag die Einstellung eines optimales Verhältnis von Fallschutzfähigkeit, Herstellungskosten, Oberflächendesign und Stabilität erlauben.Such possibilities of adapting the fall protection capability is of considerable importance for the use of the floor covering in public places, in particular with access for children and in particular at playgrounds, since the fall protection coverings installed there according to the European standard EN1177 have a particularly good fall value. The energy absorption capacity of a floor covering grid built up from the floor covering elements according to the invention or an arrangement of floor covering lattices is measured by means of a so-called HIC value (Head Injury Creation), which in particular correlates with the acceleration of a falling body upon impact. Decisive here according to the cited standard is that the drop height is as large as possible at a HIC value of 1000. This can be achieved with the flooring element according to the invention or the floor covering grid and the arrangement of floor covering grids in a simple and cost-effective manner, the said possibilities of Fallschutzfähigkeitsanpassung depending on the requirements of the flooring allow the setting of an optimum ratio of fall protection capability, manufacturing cost, surface design and stability.

Ein Gegenstand der Erfindung ist ein Bodenbelagsgitter gemäß Anspruch 1 mit einer Vielzahl der zuvor beschriebenen Bodenbelagselemente, wobei eine Mehrzahl von ersten Bodenbelagselementen in einer ersten Richtung nebeneinander und parallel zueinander angeordnet sind und eine Mehrzahl von zweiten Bodenbelagselementen in einer zur ersten Richtung senkrechten zweiten Richtung derart nebeneinander und parallel zueinander angeordnet sind, dass die dritten Teilbereiche der ersten Bodenbelagselemente in die Aussparungen der zweiten Bodenbelagselemente eingreifen. Diese Gitteranordnung, wobei die erste oder zweite Seite der ersten Bodenbelagselemente und die zweite oder erste Seite der zweiten Bodenbelagselemente die Sichtseite des Bodenbelagsgitters bilden, hat gegenüber dem Stand der Technik den Vorteil, dass eine ästhetische und natürliche Wirkung des Bodenbelags durch Auffüllen der Gitterfreiräume mit einem Füllmaterial und/oder durch Durch- bzw. Überwachsen des Gitters, bspw. mit Gras, Wiese und/oder Pflanzen, erzielt wird, ohne die Fallschutzfähigkeit einzuschränken. Als Füllmaterialen sind insbesondere Sand und/oder Erde vorgesehen, wobei somit gleichzeitig eine Fixierung des Bodenbelagsgitters gegenüber horizontalen Kraftwirkungen auf das Bodenbelagsgitter erzielt wird. Ein derartig natürlich
anmutender Bodenbelag, welcher gleichzeitig ein Höchstmaß an Fallschutzfähigkeit aufweist, ist insbesondere im Hinblick auf die Verwendung auf Kinderspielplätzen, öffentlichen Plätzen, Parks und/oder in Gärten von großer Bedeutung. Ein vegetatives Überwachsen des Bodenbelagsgitters wird ferner durch die vergleichsweise gute Wasserdurchlässigkeit des Bodenbelagsgitters begünstigt. Weiterhin ist von Vorteil, dass im Gegensatz zum Stand der Technik kein kostenintensiver Unterbau des Bodens nötig ist, insbesondere da die Gefahr des Unterspülens bei der Verwendung einer Gitterstruktur erheblich reduziert wird. Ein weiterer Vorteil ist, dass die Fallschutzwirkung durch eine Deformation der Bodenbelagselemente selbst erzielt wird, so dass keine unterhöhlten Strukturen benötigt werden, welche durch die permanente Biegebelastung deutlich kurzlebiger sind.An object of the invention is a floor covering grid according to claim 1 having a plurality of previously described flooring elements, wherein a plurality of first flooring elements are arranged side by side and parallel to each other in a first direction and a plurality of second flooring elements in a direction perpendicular to the first direction second direction are arranged side by side and parallel to each other that the third portions of the first floor covering elements in the Recesses of the second flooring elements intervene.

In particular, sand and / or earth are provided as filling materials, thus at the same time achieving fixing of the floor covering grid to horizontal force effects on the floor covering grid. Such a natural
attractive flooring, which at the same time has the highest level of fall protection capability, is of particular importance with regard to its use on children's playgrounds, public squares, parks and / or in gardens. A vegetative overgrowth of the floor covering grid is further promoted by the comparatively good water permeability of the floor covering grid. Furthermore, it is advantageous that, in contrast to the prior art, no cost-intensive foundation of the soil is necessary, in particular because the risk of under-washing when using a grid structure is significantly reduced. Another advantage is that the fall protection effect is achieved by a deformation of the flooring elements themselves, so that no undercut structures are needed, which are significantly shorter-lived by the permanent bending load.
