Description

Die vorliegende Erfindung betrifft einen Kunstrasenbelag mit einer speziellen Stützschicht, der sich insbesondere zur Verwendung für einen temporär angelegten Sport- oder Spielplatz eignet.The present invention relates to an artificial turf covering having a special supporting layer which is particularly suitable for use in a temporary sports or playground.

Kunstrasenbeläge werden insbesondere auf Sport- und Spielplätzen oft als Alternative für einen natürlichen Rasen verwendet. Gegenüber letzterem weisen Kunstrasenbeläge den Vorteil auf, dass sie über eine höhere Belastbarkeit verfügen und relativ pflegeleicht sind. Daher sind sie gerade für Fussball- oder Rugbyplätze besonders zweckmässig. Zudem sind sie im Vergleich zu einem natürlichen Rasen auch bei schlechter Witterung gut bespielbar.Artificial grass coverings are often used as an alternative to a natural lawn, especially on sports grounds and playgrounds. Compared to the latter, artificial grass coverings have the advantage that they have a higher load capacity and are relatively easy to care for. Therefore, they are especially useful for football or rugby courts. In addition, they are well playable compared to a natural lawn even in bad weather.

Solche Kunstrasenbeläge umfassen typischerweise einen Rasenflor, welcher von Florfäden aus Kunststoff gebildet wird, die auf einem Träger angebracht sind.Such artificial turf coverings typically comprise a turf formed by plastic pile threads mounted on a support.

Bei starker und/oder wiederholter mechanischer Beanspruchung können diese Florfäden gebogen oder beschädigt werden, so dass sie sich nicht mehr aufrichten. Dadurch verliert der Kunstrasenbelag seine rasenartigen Eigenschaften.Under strong and / or repeated mechanical stress these pile threads can be bent or damaged, so that they do not straighten up. As a result, the artificial turf surface loses its lawn-like properties.

Um eine mechanische Beschädigung der Florfäden zu verhindern, schlägt EP 1 696 077 vor, auf dem Träger eine Stützschicht anzubringen, welche die Florfäden im Anschluss an den Träger umschliesst. Wird ein Florfaden infolge einer Krafteinwirkung aus seiner ursprünglichen Position ausgelenkt, so verhindert diese Stützschicht, dass der Florfaden unmittelbar am Träger ausgelenkt wird. Ausserdem unterstützt die Stützschicht die Rückstellung der Florfäden.To prevent mechanical damage to the pile threads beats EP 1 696 077 on the support to provide a support layer which encloses the pile threads following the support. If a pile yarn is deflected from its original position as a result of a force, this backing layer prevents that the pile yarn is deflected directly on the carrier. In addition, the support layer supports the return of the pile threads.

Um ein "Abliegen" der Florfäden eines Kunstrasenbelags zu vermeiden, ist es zusätzlich von Vorteil, wenn die Florfäden an sich schon über ein hohes Rückstellvermögen verfügen. Gleichzeitig ist es aber auch wichtig, dass die Florfäden aus einem Material bestehen, welches nicht zu Hautverbrennungen führt, wenn ein Benutzer mit relativ hoher Geschwindigkeit über den Kunstrasen gleitet.In order to avoid a "lying" of the pile threads of an artificial turf, it is additionally advantageous if the pile threads already have a high resilience per se. At the same time it is also important that the pile threads are made of a material which does not cause skin burns when a user slides over the artificial turf at a relatively high speed.

In diesem Sinne offenbart EP 2 395 135 eine Kunststofffaser für einen Kunstrasenbelag, welche zwei verschiedene Kunststoffkomponenten umfasst. Dabei ist eine erste Kunststoffkomponente mit einem höheren Rückstellvermögen in eine zweite, besonders hautverträgliche Kunststoffkomponente eingebettet.Revealed in this sense EP 2 395 135 a plastic fiber for an artificial turf covering comprising two different plastic components. Here, a first plastic component is embedded with a higher resilience in a second, particularly skin-friendly plastic component.

Nebst dem ästhetischen Aspekt eines möglichst rasenartigen Aussehens und der Vermeidung von Hautverbrennungen bei der Nutzung ist es auch wichtig, dass der Kunstrasenbelag eine ausreichende Schockabsorption gewährleistet. Diesbezüglich fordert die DIN-Norm EN 15336 einen Kraftabbau von mindestens 50% und die FIFA 1* von mindestens 55% für Kunstrasenbeläge auf Fussballplätzen.In addition to the aesthetic aspect of a lawn-like appearance and the prevention of skin burns during use, it is also important that the artificial turf covering ensures sufficient shock absorption. In this respect, the DIN EN 15336 standard requires at least 50% reduction in force and at least 55% FIFA 1 * for artificial grass surfaces on football pitches.

Typischerweise wird daher zwischen einem Kunstrasenbelag und dem Untergrund eine zusätzliche Dämpfungsschicht angeordnet. Diese soll eine ausreichende Schockabsorption durch den Boden gewährleisten. Üblicherweise besteht die Dämpfungsschicht aus einem elastischen Material, z.B. aus gebundenen Splittern aus Styrol-Butadien-Kautschuk (SBR) und/oder aus zelligen Schäumen aus Polyurethan (PU), Polyethylen (PE) oder expandiertem Polypropylen (EPP). Die Dämpfungsschicht wird meist als Rolle mit einer Dicke ab etwa 6 mm oder in Form von einzelnen Fliesen (auch als Paneelen bezeichnet) oder als Ganzes mit einer Dicke von bis zu 30 mm bereitgestellt und auf dem Untergrund angebracht. Dabei werden vorfabrizierte Rollen oder Fliesen typischerweise lose aufgelegt und mittels Klebband oder mit Puzzle- oder Nut-Kamm-Systemen oder ähnlichem miteinander verbunden. Alternativ können beispielsweise SBR-Splitter zusammen mit Klebstoff in pastöser Form als ganze Dämpfungsschicht auf dem Untergrund ausgetragen werden.Typically, therefore, an additional damping layer is placed between an artificial turf and the ground. This should ensure sufficient shock absorption through the floor. Usually, the damping layer consists of an elastic material, for example, bonded splinters of styrene-butadiene rubber (SBR) and / or cellular foams of polyurethane (PU), polyethylene (PE) or expanded polypropylene (EPP). The Damping layer is usually provided as a roll with a thickness from about 6 mm or in the form of individual tiles (also referred to as panels) or as a whole with a thickness of up to 30 mm and attached to the substrate. Prefabricated rolls or tiles are typically laid loosely and bonded together by means of adhesive tape or with puzzle or grooved comb systems or the like. Alternatively, for example, SBR splinters can be discharged together with adhesive in pasty form as a whole damping layer on the substrate.

EP 1 983 104 offenbart einen Kunstrasen mit einer Basisschicht und einer Vielzahl von Halmen, die an der Basisschicht fixiert sind. Auf der Basisschicht und zwischen den Halmen ist ein Dämpfungsmaterial angeordnet, welches aus Mehrkomponenten-Kunststofffasern besteht. Eine Verfüllung soll in diesem Fall nicht mehr nötig sein, um die gewünschten Dämpfungseigenschaften zu erzielen. EP 1 983 104 discloses an artificial turf having a base layer and a plurality of blades fixed to the base layer. On the base layer and between the blades, a damping material is arranged, which consists of multi-component plastic fibers. A backfilling should not be necessary in this case, in order to achieve the desired damping properties.

Zusätzlich oder alternativ dazu kann eine verbesserte Schockabsorption auch durch Aufbringen eines Kunststoffgranulats auf den Träger des Kunstrasenbelags, wie etwa in EP 2 331 56 offenbart, erreicht werden. Solche Kunstrasenbeläge werden auch als "verfüllt" bezeichnet.Additionally or alternatively, improved shock absorption can also be achieved by applying a plastic granulate to the support of the artificial turf covering, such as in FIG EP 2 331 56 disclosed to be achieved. Such artificial turf coverings are also referred to as "filled in".

Sowohl ein Kunststoffgranulat als auch eine zusätzliche Dämpfungsschicht führen jedoch dazu, dass die Installation des Kunstrasenbelags deutlich aufwändiger wird und das Gewicht des zu transportierenden bzw. zu verlegenden Materials signifikant erhöht wird.Both a plastic granulate and an additional damping layer, however, lead to the installation of artificial turf flooring is significantly more complex and the weight of the material to be transported or to be laid material is significantly increased.

Gerade für temporäre Anwendungen, wie beispielsweise die Nutzung einer Kunsteisbahn als Sport- oder Spielplatz im Sommer, wäre aber ein Kunstrasenbelag wünschenswert, der sehr einfach transportiert, verlegt und auch wieder entfernt werden kann.Especially for temporary applications, such as the use of an artificial ice rink as a sports or playground in the summer, but an artificial turf would be desirable, the very easy to transport, relocated and can be removed again.

Es ist daher eine Aufgabe der vorliegenden Erfindung, einen Kunstrasenbelag zur Verfügung zu stellen, der besonders einfach installiert und auch wieder entfernt werden kann und dabei gleichzeitig die Anforderungen bezüglich rasenartigem Aussehen, Hautfreundlichkeit und Schockabsorption erfüllt.It is therefore an object of the present invention to provide an artificial turf covering which is particularly easy to install and remove, while at the same time fulfilling the requirements of turf-like appearance, skin friendliness and shock absorption.

Diese Aufgabe wird gelöst durch den Kunstrasenbelag gemäss Anspruch 1 sowie dessen Verwendung gemäss Anspruch 10. Bevorzugte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This object is achieved by the artificial turf covering according to claim 1 and its use according to claim 10. Preferred embodiments are the subject of the dependent claims.

Der erfindungsgemässe Kunstrasenbelag umfasst einen flächigen Träger mit einer Oberseite und einer Unterseite, einen Rasenflor, der aus Florfäden gebildet ist, welche mit dem Träger verbunden sind, und eine auf der Oberseite des Trägers angeordnete, von den Florfäden des Rasenflors durchdrungene Stützschicht, welche ausschliesslich aus Stützfilamenten besteht. Der erfindungsgemässe Kunstrasenbelag ist dadurch gekennzeichnet, dass die Stützschicht eine Höhe von mindestens 2 cm und eine Dichte von mindestens 0.095 g/cm3 aufweist und dass die Stützschicht aus Polyamid oder Polyurethan besteht.The artificial turf covering according to the invention comprises a flat carrier with a top side and a bottom side, a turf formed by pile threads which are connected to the carrier, and a support layer, which is arranged on the upper side of the carrier and penetrated by the tuft threads of the turf, which exclusively consists of Support filaments exists. The artificial turf covering according to the invention is characterized in that the supporting layer has a height of at least 2 cm and a density of at least 0.095 g / cm 3 and that the supporting layer consists of polyamide or polyurethane.

Beim erfindungsgemässen Kunstrasenbelag dient die Stützschicht nicht nur dazu, ausgelenkte Florfäden wieder aufzurichten, sondern sie verleiht dem Kunstrasenbelag gleichzeitig auch noch eine ausreichende Schockabsorption. Dadurch ist es nicht nötig, zusätzlich ein Granulat oder eine Dämpfungsschicht zu verwenden.In the artificial turf covering according to the invention, the supporting layer not only serves to erect deflected pile threads, but also gives the artificial turf covering sufficient shock absorption at the same time. As a result, it is not necessary to additionally use a granulate or a damping layer.

Der erfindungsgemässe Kunstrasenbelag liefert somit eine vollumfassende Lösung für einen Rasenbelag, der sehr einfach transportiert, installiert und auch wieder entfernt werden kann. Er eignet sich dadurch insbesondere für kurzzeitige Anwendungen, bei denen der Kunstrasenbelag nur vorübergehend verwendet werden soll. Insbesondere ist das Gewicht des Materials, das für den Kunstrasenbelag nötig ist, aufgrund des Wegfalls der Notwendigkeit einer Dämpfungsschicht bzw. eines Kunststoffgranulats im Vergleich zu früheren Lösungen signifikant verringert.The inventive artificial turf flooring thus provides a complete solution for a turf that can be very easily transported, installed and also removed again. It is therefore particularly suitable for short-term applications in which the artificial turf is to be used only temporarily. In particular, the weight of the material needed for the artificial turf flooring is significantly reduced due to the elimination of the need for a cushioning layer or plastic granulate compared to previous solutions.

Der erfindungsgemässe Kunstrasenbelag kann direkt auf einem Untergrund ausgelegt werden, ohne dass eine zusätzliche Dämpfungsschicht zur Schockabsorption nötig wäre. So beträgt der Kraftabbau des erfindungsgemässen Rasenbelags etwa 55-57%. Dieser Wert liegt oberhalb des gemäss der DIN-Norm EN 15336 geforderten Werts von 50% und demjenigen der FIFA 1* von 55%. Er ist daher bestens geeignet für Anwendungen im Sportbereich, insbesondere für Fussball oder Rugby.The artificial turf flooring according to the invention can be designed directly on a substrate without the need for an additional damping layer for shock absorption. Thus, the force reduction of the inventive turf is about 55-57%. This value is above the 50% required by DIN EN 15336 and 55% by FIFA 1 *. It is therefore ideal for sports applications, in particular for football or rugby.

Zudem hat sich gezeigt, dass die elastischen Eigenschaften des erfindungsgemässen Kunstrasenbelags, welche die Schockabsorption gewährleisten, durch mechanische Beanspruchung nicht abnehmen, so dass er über längere Zeit und/oder mehrfach eingesetzt werden kann.In addition, it has been shown that the elastic properties of the artificial turf covering according to the invention, which ensure shock absorption, do not decrease due to mechanical stress, so that it can be used over a longer period of time and / or multiple times.

Beim erfindungsgemässen Kunstrasenbelag wird ein flächiger Träger verwendet, wie er aus dem Stand der Technik (z.B. EP 2 333 156 ) bekannt ist. Dieser ist vorzugsweise dimensionsstabil und weist daher eine hohe Ortsfestigkeit auf. Als Material für den Träger kann beispielsweise Polypropylen, Polyester, Polyamid und/oder ein Glasfasern enthaltendes Material verwendet werden. Der Träger kann ein- oder mehrlagig sein und zusätzlich einen Glasfasern enthaltenden Hilfsträger umfassen.When artificial turf flooring according to the invention, a flat carrier is used, as of the prior art (eg EP 2 333 156 ) is known. This is preferably dimensionally stable and therefore has a high local strength. As the material for the support, for example, polypropylene, polyester, polyamide and / or a material containing glass fibers may be used. The carrier can be one or more layers and additionally comprise a glass substrate containing auxiliary carrier.

Die erfindungsgemässe Stützschicht besteht ausschliesslich aus Stützfilamenten, welche üblicherweise etwas kürzer sind als die Florfäden des Rasenflors und zwischen diesen Florfäden angeordnet sind. Sowohl Florfäden als auch Stützfilamente sind mit dem Träger verbunden, beispielsweise durch Tuften.The support layer according to the invention consists exclusively of support filaments, which are usually somewhat shorter than the pile threads of the turf and are arranged between these pile threads. Both pile threads and support filaments are connected to the carrier, for example by tufting.

Die Stützschicht besteht ausschliesslich aus Stützfilamenten. Dies erlaubt eine besonders einfache Herstellung des erfindungsgemässen Kunstrasenbelags. Insbesondere kann der erfindungsgemässe Kunstrasenbelag durch Tufting in einem einzigen Arbeitsschritt hergestellt werden, wobei sowohl die Florfäden als auch die Stützfilamente mit dem Träger verbunden werden.The supporting layer consists exclusively of supporting filaments. This allows a particularly simple production of the artificial turf flooring according to the invention. In particular, the artificial turf covering according to the invention can be produced by tufting in a single working step, wherein both the pile threads and the supporting filaments are connected to the carrier.

Alternativ ist es auch möglich, dass die Stützschicht zusätzlich zu den Stützfilamenten eine auf der Oberseite des flächigen Trägers angeordnete Filzauflage umfasst. Diese Filzauflage wird ebenfalls von den Florfäden und Stützfilamenten durchdrungen.Alternatively, it is also possible for the support layer to comprise, in addition to the support filaments, a felt support arranged on the upper side of the flat support. This felt pad is also penetrated by the pile threads and support filaments.

Erfindungsgemäss besteht die Stützschicht aus Polyamidoder Polyurethan. Diese Materialien eignen sich besonders gut für die Herstellung von Stützfilamenten und/oder einer Filzauflage. Besonders bevorzugt besteht die Stützschicht aus Polyamid.According to the invention, the support layer consists of polyamide or polyurethane. These materials are particularly suitable for the production of support filaments and / or a felt pad. Particularly preferably, the support layer consists of polyamide.

In einer bevorzugten Ausführungsform sind die Stützfilamente der Stützschicht gekräuselt oder texturiert. Eine solche gekräuselte oder texturierte Struktur wird nach allgemein bekannten Verfahren bei der Herstellung der Stützfilamente erzielt. Durch diese gekräuselte oder texturierte Ausgestaltung werden nicht nur das Stützvermögen und die Stossdämpfung der Stützschicht weiter verbessert, sondern auch die Griffigkeit des Kunstrasenbelags insgesamt.In a preferred embodiment, the support filaments of the support layer are crimped or textured. Such a crimped or textured structure is achieved by well known processes in the manufacture of the support filaments. Through this Curled or textured design not only the support and shock absorption of the support layer are further improved, but also the grip of the artificial turf surface as a whole.

In einer bevorzugten Ausführungsform bestehen die Florfäden des Rasenflors aus einer ersten Komponente aus Polyethylen und einer in die erste Komponente eingebetteten zweiten Komponente aus Polyamid. Solche Florfäden sind in der EP 2 395 135 offenbart, deren Offenbarung in Bezug auf die Rasenflorfasern hiermit durch Verweis vollumfänglich einbezogen wird. Diese Florfäden zeichnen sich durch ein besonders gutes Rückstellvermögen und eine sehr gute Hautverträglichkeit aus. Zusätzlich oder alternativ können die in EP 2 395 135 offenbarten Fasern auch für die Stützfilamente des erfindungsgemässen Kunstrasenbelags verwendet werden.In a preferred embodiment, the pile threads of the turf pile consist of a first component of polyethylene and a second component of polyamide embedded in the first component. Such pile threads are in the EP 2 395 135 , the disclosure of which is incorporated herein by reference in its entirety. These pile threads are characterized by a particularly good resilience and a very good skin compatibility. Additionally or alternatively, the in EP 2 395 135 disclosed fibers are also used for the supporting filaments of the inventive synthetic turf flooring.

In einer bevorzugten Ausführungsform weisen die Florfäden des Rasenflors von der Oberseite des Trägers aus gemessen eine Länge von 2.5 bis 4.0 cm auf. Diese Länge entspricht einer üblichen Rasenhöhe für Spiel- und Sportplätze.In a preferred embodiment, the pile threads of the turf pile measured from the top of the wearer have a length of 2.5 to 4.0 cm. This length corresponds to a standard lawn height for playing and sports fields.

In einer bevorzugten Ausführungsform ist ein erster Teil der Florfäden des Rasenflors, von der Oberfläche des Trägers an gemessen, länger als ein zweiter Teil der Florfäden des Rasenflors, insbesondere um 5 bis 10 mm länger. Durch diese unterschiedlich lange Ausgestaltung der Florfäden wird der ästhetische Aspekt des Kunstrasenbelags weiter verbessert, da auch bei einem natürlichen Rasen nicht alle Grashalme dieselbe Länge aufweisen. Besonders bevorzugt ist es, dass der erste Teil der Florfäden des Rasenflors zudem steifer ist als der zweite Teil der Florfäden des Rasenflors.In a preferred embodiment, a first part of the pile threads of the turf, measured from the surface of the wearer, is longer than a second part of the pile threads of the turf, in particular by 5 to 10 mm longer. By this different length design of the pile threads of the aesthetic aspect of the artificial turf is further improved, since not all grass blades have the same length even with a natural turf. It is particularly preferred that the first part of the pile threads of the turf is also stiffer than the second part of the pile threads of the turf.

Bei geeigneter Wahl der Länge der Florfäden bzw. des Unterschieds in der Länge des ersten Teils der Florfäden zum zweiten Teil der Florfäden erlaubt es diese Ausführungsform einerseits, ein im Vergleich zu einem Naturrasen täuschend ähnlich aussehendes Erscheinungsbild von hoher Authentizität zu erhalten. Diese kann dadurch noch erhöht werden, dass für die Florfäden des erstens Teils und die Florfäden des zweiten Teils unterschiedliche Grünabstufungen verwendet werden. Insbesondere wird für die Florfäden des zweiten Teils ein helleres Grün verwendet als für die Florfäden des ersten Teils.With a suitable choice of the length of the pile threads or the difference in the length of the first part of the pile threads to the second part of the pile threads, this embodiment allows on the one hand, to obtain a deceptively similar looking appearance of high authenticity compared to a natural turf. This can be further increased by the fact that different green shades are used for the pile threads of the first part and the pile threads of the second part. In particular, a lighter green is used for the pile threads of the second part than for the pile threads of the first part.

Andererseits erlaubt es die besagte Ausführungsform, das Ballrollverhalten und das Ballrückspringverhalten insbesondere hinsichtlich der Verwendung des Kunstrasenbelags für einen Fussballplatz zu optimieren.On the other hand, the said embodiment makes it possible to optimize the ball rolling behavior and the ball rebound behavior, in particular with regard to the use of the artificial turf covering for a soccer field.

Anstelle unterschiedlicher Florfadenlängen kann insbesondere hinsichtlich des optischen Erscheinungsbilds ein ähnlicher Effekt erzielt werden, wenn ein Teil der Florfäden texturiert wird.Instead of different pile thread lengths, a similar effect can be achieved, in particular with regard to the visual appearance, if a part of the pile threads is textured.

Der erfindungsgemässe Rasenflor wird vorzugsweise mittels eines Tuftingverfahrens hergestellt. Dies erlaubt eine sehr einfache Fertigung des Kunstrasenbelags und eine sichere Verbindung der Florfäden mit dem Träger. Der Rasenflor weist vorzugsweise eine Stichdichte im Bereich von 20'000 bis 30'000 pro Quadratmeter auf. Die Garnfeinheit der Florfäden liegt vorzugsweise in einem Bereich von 1'000 bis 2'000 dtex pro Florfaden.The turf according to the invention is preferably produced by means of a tufting process. This allows a very simple production of artificial turf flooring and a secure connection of the pile threads with the wearer. The turf preferably has a stitch density in the range of 20,000 to 30,000 per square meter. The yarn count of the pile yarns is preferably in a range of 1'000 to 2'000 dtex per pile yarn.

In einer bevorzugten Ausführungsform werden auch die Stützfilamente der Stützschicht mittels Tufting mit dem Träger verbunden.In a preferred embodiment, the supporting filaments of the support layer are also connected to the carrier by means of tufting.

Gemäss einer besonders bevorzugten Ausführungsform ist der erfindungsgemässe Kunstrasenbelag unverfüllt, das heisst, dass er nicht mit einem Granulat oder einem ähnlichen Material, z. B. Sand, versehen ist. Durch diese Ausgestaltung wird einerseits das Gewicht des Kunstrasenbelags signifikant verringert und andererseits auch das Installieren des Belags deutlich vereinfacht.According to a particularly preferred embodiment, the artificial turf covering according to the invention is unfilled, that is to say that it is not filled with granules or a similar material, e.g. B. sand, is provided. On account of this embodiment, on the one hand, the weight of the synthetic turf covering is significantly reduced and, on the other hand, the installation of the covering is also considerably simplified.

In einem weiteren Aspekt betrifft die vorliegende Erfindung die Verwendung des erfindungsgemässen Kunstrasenbelags für einen Sportplatz oder Spielplatz, insbesondere für einen Fussballplatz oder einen Rugbyplatz. Dabei wird der Kunstrasenbelag auf einem festen Untergrund angeordnet. Vorzugsweise wird dabei zwischen dem Kunstrasenbelag und dem Untergrund keine Dämpfungsschicht angeordnet. Eine besonders hohe Ortsfestigkeit wird dann erzielt, wenn der Kunstrasenbelag am Randbereich des Sport- oder Spielplatzes mit dem Untergrund verschraubt oder verklebt wird.In a further aspect, the present invention relates to the use of the artificial turf flooring according to the invention for a sports field or playground, in particular for a football field or a rugby court. Here, the artificial turf is arranged on a solid surface. Preferably, no damping layer is arranged between the artificial turf covering and the substrate. A particularly high local strength is achieved when the artificial turf covering is screwed or glued to the substrate at the edge of the sports or playground.

Der erfindungsgemässe Kunstrasenbelag lässt sich problemlos und rasch am gewünschten Ort auslegen und kann sehr leicht dorthin transportiert werden. Er ist daher besonders geeignet für eine Anwendung im Bereich von Kleinspielfeldern oder für die sommerliche Nutzung von Kunsteisplätzen sowie für Indoor- oder Outdoor-Events, bei denen der Kunstrasenbelag nur während einer relativ kurzen Zeit verwendet werden soll.The artificial turf flooring according to the invention can be easily and quickly laid out at the desired location and can be transported there very easily. It is therefore particularly suitable for use in the field of small playgrounds or for the summer use of artificial ice rinks as well as for indoor or outdoor events in which the artificial turf is to be used only for a relatively short time.

In den meisten Fällen ist dabei keine spezielle Befestigung zum Untergrund nötig. Der erfindungsgemässe Kunstrasenbelag wird typischerweise in Form von Bahnen hergestellt, welche nebeneinander ausgelegt werden und durch stumpfes Aneinanderstossen oder durch Kletten miteinander verbunden werden.In most cases, no special attachment to the ground is necessary. The artificial turf flooring according to the invention is typically produced in the form of webs which are designed side by side and be joined by blunt abutment or by burdock.

Alternativ kann der erfindungsgemässe Kunstrasenbelag auch in Form von Fliesen (auch als Paneelen bezeichnet) zur Verfügung gestellt werden. Diese lassen sich besonders leicht transportieren und auslegen, da sie aufgrund ihrer Grösse relativ handlich sind. Solche Fliesen werden vorzugsweise mithilfe eines Klettsystems, beispielsweise mit einem Haken/Flausch Verschluss, wie ihn die Linie Klettostar® der Firma Gottlieb Binder GmbH & Co KG (Holzgerlingen, Deutschland) aufweist, auf dem Untergrund befestigt. Dabei wird auf der Unterseite der Fliesen der eine Teil des Klettsystems (im Folgenden als "Fliesenteil" bezeichnet) und auf dem Boden der andere Teil des Klettsystems (im Folgenden als "Bodenteil" bezeichnet) befestigt, vorzugsweise bei den Fliesen jeweils im Bereich der vier Ecken und auf dem Untergrund so, dass jeder Bodenteil des Klettsystems jeweils mit vier Fliesenteilen von vier verschiedenen Fliesen zusammenwirken kann. Beispielsweise kann auf den Fliesen in jeder Ecke ein etwa 10 x 10 cm grosses Stück Klettostar® Haft und auf dem Untergrund ein etwa 21 x 21 cm grosses Stück Klettostar® Flausch angebracht sein, so dass im ausgelegten Zustand die vier Ecken der Fliesen in der Mitte des Klettostar® Flausch Stückes zusammentreffen.Alternatively, the artificial turf flooring according to the invention can also be provided in the form of tiles (also referred to as panels). These are particularly easy to transport and lay out because they are relatively handy because of their size. Such tiles are preferably fastened to the substrate with the aid of a Velcro system, for example with a hook / loop closure, such as the Klettostar® line from Gottlieb Binder GmbH & Co. KG (Holzgerlingen, Germany). In this case, on the underside of the tiles one part of the Velcro system (hereinafter referred to as "tile part") and on the bottom of the other part of the Velcro system (hereinafter referred to as "bottom part") attached, preferably in the tiles in each case in the four Corners and on the ground so that each bottom part of the Velcro system can each interact with four tile parts of four different tiles. For example, a piece of Klettostar® adhesive about 10 x 10 cm in size can be placed on the tiles in each corner, and a piece of Klettostar® Velcro about 21 x 21 cm in size on the surface so that the four corners of the tile in the center are in the laid out condition of the Klettostar® Velcro Piece.

Zudem verfügt der erfindungsgemässe Kunstrasenbelag über eine hohe Belastbarkeit, so dass er sich besonders gut für Anwendungen mit einer starken Beanspruchung eignet, z.B. für Rugby oder Fussball.In addition, the synthetic turf covering according to the invention has a high load-bearing capacity, so that it is particularly well suited for applications with a high load, e.g. for rugby or football.

In einem weiteren Aspekt betrifft die vorliegende Erfindung auch ein Kunstrasen-System, umfassend den erfindungsgemässen Kunstrasenbelag. Dieses Kunstrasen-System kann direkt auf einem festen Untergrund ausgelegt werden und erfordert keine zusätzliche Dämpfungsschicht oder Verfüllung (z.B. Kunststoffgranulat oder Sand). Das Kunstrasen-System besteht also im Wesentlichen aus dem erfindungsgemässen Kunstrasenbelag.In a further aspect, the present invention also relates to an artificial turf system comprising the artificial turf flooring according to the invention. This artificial turf system can be designed directly on a solid surface and does not require any additional damping layer or backfilling (eg plastic granulate or sand). The artificial turf system thus consists essentially of the artificial turf flooring according to the invention.

Dieses Kunstrasen-System enthält den erfindungsgemässen Kunstrasenbelag vorzugsweise in Form von Bahnen oder Fliesen. Dadurch lässt er sich besonders leicht zum Ort der Verwendung transportieren, auslegen und später auch wieder entfernen. Typischerweise weist eine solche Bahn eine Breite von etwa 2 m auf und, sofern es das Gewicht erlaubt, eine Länge, die der kürzeren Seite des mit dem Kunstrasenbelag zu versehenden Untergrunds entspricht. Fliesen sind grundsätzlich in beliebiger Grösse möglich, wobei Grössen von 0.25 bis 4 m2 bevorzugt sind.This artificial turf system preferably contains the artificial turf covering according to the invention in the form of webs or tiles. This makes it particularly easy to transport to the place of use, interpret and later remove it. Typically, such a web has a width of about 2 meters and, if weight permits, a length corresponding to the shorter side of the surface to be turfed. Tiles are basically possible in any size, with sizes of 0.25 to 4 m 2 are preferred.

Das erfindungsgemässe Kunstrasen-System kann zusätzlich auch noch Mittel zur Verbindung des Kunstrasenbelags umfassen, beispielsweise ein Klettsystem, oder in Form eines bekannten "Puzzle-Systems" bereitgestellt werden.The artificial turf system according to the invention may additionally also comprise means for connecting the artificial turf covering, for example a Velcro system, or provided in the form of a known "puzzle system".

Besonders bevorzugt umfasst das erfindungsgemässe Kunstrasen-System zusätzlich ein Klettsystem mit einem Haken/Flausch-Verschluss, insbesondere entsprechende Elemente aus der Linie Klettostar® der Firma Gottlieb Binder GmbH & Co KG (Holzgerlingen, Deutschland).Particularly preferably, the artificial turf system according to the invention additionally comprises a hook-and-loop fastener system, in particular corresponding elements from the Klettostar® line of Gottlieb Binder GmbH & Co. KG (Holzgerlingen, Germany).

So kann das erfindungsgemässe Kunstrasen-System zum Beispiel eine einzelne Fliese des erfindungsgemässen Kunstrasenbelags aufweisen, auf deren Unterseite jeweils in den Ecken ein etwa 10 x 10 cm grosses Stück Klettostar® Haft als Fliesenteil befestigt ist, und zusätzlich zwei etwa 21 x 21 cm grosse Stücke Klettostar® Flausch, die vom Anwender auf dem Untergrund als Bodenteil angebracht werden sollen. Alternativ können Klettostar® Haft und Klettostar® Flausch natürlich auch vertauscht werden oder in anderen Dimensionen vorliegen.For example, the artificial turf system according to the invention can have, for example, a single tile of the artificial turf covering according to the invention, on the underside of which an approximately 10 x 10 cm piece of Klettostar® adhesive is attached as a tile part, and additionally two pieces about 21 x 21 cm in size Klettostar® Velcro made by Users should be mounted on the ground as the bottom part. Alternatively, Klettostar® Haft and Klettostar® Flausch can of course also be exchanged or be available in other dimensions.

Ein Kunstrasen-System mit einem Klettsystem bietet eine erhöhte Flexibilität bei der Verlegung, da die Grösse des zu verlegenden Kunstrasens individuell an die Bedürfnisse des Nutzers angepasst werden können. Zudem erlaubt es eine besonders rasche und einfache Verlegung und kann auch problemlos wieder entfernt werden. Dabei eignen sich die besonders stabilen Fliesen des erfindungsgemässen Kunstrasenbelags besonders gut für eine Verwendung mit einem Klettsystem.An artificial turf system with a Velcro system offers increased flexibility in laying, as the size of the artificial turf to be laid can be individually adapted to the needs of the user. In addition, it allows a particularly quick and easy installation and can also be easily removed. The particularly stable tiles of the artificial turf flooring according to the invention are particularly well suited for use with a Velcro system.

Die Nutzschicht 34 weist ebenfalls einen Träger 40, eine Stützschicht 42 und einen rasenartigen, aus Florfäden 44 gebildeten Flor 46 auf. Die in Figur 2 gezeigte Stützschicht 42 ist jedoch durch ein kontinuierliches Flächengebilde 48, beispielsweise ein Vlies, gebildet. Die Florfäden 44 sind mit dem Träger 40 durch Tuften verbunden und durchdringen das kontinuierliche Flächengebilde 48, welches auf dem Träger 40 aufliegt. Auch beim Kunstrasenbelag 30 gemäss EP 1 696 077 dient die Stützschicht 42 dazu, ausgelenkte Florfäden 44 wieder aufzurichten.The wear layer 34 likewise has a carrier 40, a support layer 42 and a turf-like pile 46 formed from pile threads 44. In the FIG. 2 However, shown support layer 42 is formed by a continuous sheet 48, for example, a nonwoven. The pile threads 44 are connected to the carrier 40 by tufts and penetrate the continuous sheet 48, which rests on the carrier 40. Also with the artificial turf 30 according to EP 1 696 077 serves the support layer 42 to erect deflected pile threads 44 again.

Figur 3 zeigt einen Querschnitt durch einen Kunstrasenbelag 50 gemäss EP 2 333 156 . Dieser weist einen Unterteil 52 und einen darüber angeordneten Nutzteil 54 auf. Der Unterteil 52 umfasst eine Elastikschicht 56 und mindestens eine zusätzliche Trägerschicht 58, welche eine ausreichende Stossdämpfung und eine zuverlässige Abführung von versickertem Wasser garantieren sollen. FIG. 3 shows a cross section through an artificial turf 50 according to EP 2 333 156 , This has a lower part 52 and a utility part 54 arranged above it. The lower part 52 comprises an elastic layer 56 and at least one additional carrier layer 58, which are to guarantee sufficient shock absorption and reliable drainage of seepage water.

Der Nutzteil 54 weist einen Träger 60 und einen rasenartigen Flor 62 auf, wobei letzterer aus ersten, längeren Florfäden 64 und zweiten, kürzeren Florfäden 66 gebildet ist. Die Florfäden 64, 66 sind wiederum durch Tuften mit dem Träger 60 verbunden. Unmittelbar auf der Oberfläche des Trägers 60 ist eine Kunststoffgranulatschicht 68 angeordnet. Diese bewirkt eine zusätzliche Stossdämpfung.The useful part 54 has a carrier 60 and a lawn-like pile 62, the latter being formed by first, longer pile threads 64 and second, shorter pile threads 66. The pile threads 64, 66 are again by Tuften connected to the carrier 60. Immediately on the surface of the carrier 60, a plastic granule layer 68 is arranged. This causes additional shock absorption.

Figur 4 zeigt einen Querschnitt durch einen erfindungsgemässen Kunstrasenbelag 70 gemäss einer ersten bevorzugten Ausführungsform. Dieser Kunstrasenbelag 70 ist direkt - d.h. ohne eine zusätzliche Dämpfungsschicht - auf einem Untergrund 72 angeordnet. FIG. 4 shows a cross section through an inventive Kunstrasenbelag 70 according to a first preferred embodiment. This artificial turf covering 70 is arranged directly - ie without an additional damping layer - on a substrate 72.
