Abstract

Described is a pile-fabric strip floor-covering for sports surfaces, in particular synthetic-grass surfaces. The floor-covering has a substrate which has apertures in it and is therefore permeable to water. Attached to the substrate are pile elements which form the pile, plus a thick elastic layer of plastic material on the underside of the substrate. To increase the water-retention capacity of the floor-covering, the plastic layer is made of open-cell cellular-plastic material, and there is a storage layer with water-retention properties on the underside of the cellular-plastic layer.

Description

Bodenbelagsbahn für Sportflächen, insbesondere Kunstrasen Floor covering for sports surfaces, especially artificial turf
Die Erfindung betrifft eine als Polware ausgebildete Bodenbe¬ lagsbahn für Sportflächen, insbesondere einen Kunstrasen, mit einer Öffnungen aufweisenden und deshalb wasserdurchlässigen Trägerbahn, mit an letzterer befestigten, den Pol bildenden Polelementen sowie einer an der Unterseite der Trägerbahn an¬ geordneten dickenelastischen KunststoffSchicht.The invention relates to a floor covering sheet for sports surfaces, in particular an artificial turf, designed as a pile fabric, with a support sheet which has openings and is therefore water-permeable, with pole elements attached to the latter, forming the pole, and with a thick-elastic plastic layer arranged on the underside of the support sheet.
Als Bodenbeläge für Sportflächen haben sich in erheblichem Umfang sogenannte Kunstrasen durchgesetzt, bei denen es sich um aus Kunststoffbändchen und/oder Kunststoffgarnen herge¬ stellte gestrickte, gewirkte, gewebte oder getuftete textile Erzeugnisse in Form einer sogenannten Polware handelt. Meist werden die die Grashalme simulierenden Polelemente aus Kunst¬ stoffbändchen hergestellt, welche die Trägerbahn durchsetzen und in dieser durch eine textile Einbindung und/oder ( letzte¬ res insbesondere bei einer sogenannten Tuftingware) durch eine partielle oder vollflächige Rückenbeschichtung der Trä¬ gerbahn mittels einer Kunststoffmasse fixiert sind.So-called artificial turf has become widely used as floor coverings for sports areas, which are knitted, knitted, woven, woven or tufted textile products in the form of a so-called pile fabric, made from plastic tapes and / or plastic yarns. The pole elements simulating the blades of grass are usually produced from plastic tapes which penetrate the carrier web and in it by means of a textile integration and / or (the latter, in particular in the case of a so-called tufting product) by a partial or full-area back coating of the carrier web by means of a plastic compound are fixed.
Da insbesondere an im Freien befindliche Sportflächen die Forderung gestellt wird, daß der Bodenbelag wasserdurchlässig ist, besitzt die Trägerbahn bekannter Kunstrasen Öffnungen, und bei einer partiellen Rückenbeschichtung beseitigt letzte¬ re die Wasserdurchlässigkeit des Bodenbelags nicht. Es sind aber auch Bodenbeläge der eingangs erwähnten Art mit einer vollflächigen Rückenbeschichtung in Form einer dickenela¬ stischen Kunststoffschicht bekannt, bei der es sich um eine Kunststoffschicht aus geschlossenzelligem Schaumkunststoff handeln kann; um in einem solchen Fall die Wasserdurchläs¬ sigkeit des Bodenbelags herbeizuführen, muß die Rückenbe¬ schichtung gelocht werden. Alle diese bekannten, vorstehend beschriebenen wasserdurch¬ lässigen Bodenbeläge haben den Nachteil, daß an der Oberflä¬ che des Bodenbelags anfällendes Wasser unkontrolliert und verhältnismäßig rasch durch den Bodenbelag hindurchtritt und letzterer dann verhältnismäßig schnell wieder abtrocknet. Es hat sich aber gezeigt, daß die Bespieleigenschaften eines Bodenbelags der in Rede stehenden Art, insbesondere also eines sogenannten Kunstrasens, ganz wesentlich davon abhän¬ gen, ob die Belagsoberfläche etwas feucht ist - letzteres führt zu sehr viel besseren Bespieleigenschaften.Since the requirement is placed in particular on outdoor sports surfaces that the floor covering is permeable to water, the carrier web of known artificial turf has openings, and with a partial back coating the latter does not remove the water permeability of the floor covering. However, floor coverings of the type mentioned at the outset with a full-surface back coating in the form of a thick plastic layer are known, which may be a plastic layer made of closed-cell foam plastic; In order to bring about the water permeability of the floor covering in such a case, the back coating must be perforated. All these known, above-described water-permeable floor coverings have the disadvantage that water susceptible to the surface of the floor covering passes through the floor covering in an uncontrolled and relatively rapid manner and then dries the latter again relatively quickly. It has been shown, however, that the example properties of a floor covering of the type in question, in particular a so-called artificial turf, depend very much on whether the surface of the surface is somewhat damp - the latter leads to much better example properties.
Der Erfindung lag die Aufgabe zugrunde, einen als Polware ausgebildeten wasserdurchlässigen Bodenbelag für Sportflä¬ chen, insbesondere einen Kunstrasen, zu schaffen, der im wesentlichen die gleichen vorteilhaften Eigenschaften wie die bekannten Bodenbeläge der vorstehend geschilderten Art auf¬ weist, jedoch nach einer Befeuchtung, der Belagsoberfläche länger als die bekannten Bodenbeläge die erwünschten Bespiel- eigenschaften beibehält.The object of the invention was to create a water-permeable floor covering for sports surfaces, in particular an artificial turf, which is designed as a pile fabric and has essentially the same advantageous properties as the known floor coverings of the type described above, but after moistening, the Floor surface longer than the known floor coverings maintains the desired playing properties.
Ausgehend von einem Bodenbelag der eingangs erwähnten Art läßt sich diese Aufgabe erfindungsgemäß dadurch lösen, daß unterhalb der Trägerbahn ein Wasserspeicher und eine Schicht vorgesehen werden, welch letztere während der Nutzung des Bodenbelags den Rücktransport des Wassers vom Wasserspeicher in die oberen Regionen des Bodenbelags bewerkstelligt. Insbe¬ sondere wird zur Lösung der gestellten Aufgabe vorgeschlagen, bei einer Bodenbelagsbahn der eingangs erwähnten Art die Kunststoffschicht aus einem offenzelligen Schaumkunststoff (z.B. Latexschäume, Polyurethanschaum, Moosgummi oder ähnliches) zu bilden und an der Unterseite der Schaumkunst¬ stoffschicht eine Speicherschicht (z.B. Faservliese, Nadelfilze, Schwergewebe, offenzellige Schäume oder ähnliches) mit wasserspeichernden Eigenschaften vorzusehen. Bei Regen oder einer Befeuchtung des Bodenbelags auf dessen Oberseite anfallendes Wasser tritt durch die Öffnungen der Trägerbahn hindurch in die offenzellige Schaumkunst¬ stoffschicht ein und gelangt von dieser aufgrund der Schwer¬ kraft und/oder einer Kapillarwirkung in die Speicherschicht, welche das Wasser aufsaugt, bis ihr Speichervolumen erschöpft ist; nicht mehr speicherbares und an der Belagsoberfläche an¬ fallendes Wasser tritt durch die Speicherschicht hindurch nach unten aus dem Bodenbelag aus und wird in den Unterbau abgeleitet oder fließt auf der Oberfläche eines wasserun¬ durchlässigen Unterbaus seitlich ab. Nach Ende des Regens bzw. der Beregnung des Bodenbelags trocknet dessen Oberfläche z. B. durch Sonne und Wind relativ schnell ab, beim Bespielen des erfindungsgemäßen Bodenbelags wird jedoch durch Druck auf die Belagsoberfläche (z. B. durch den Fuß eines Spielers) der offenzellige Schaumkunststoff zusammengedrückt und dadurch die Belagsoberfläche wieder etwas angefeuchtet, so daß sich der erwünschte Gleiteffekt durch einen Wasserfilm wieder ein¬ stellt (Pump- and Play-System). Dieser Vorgang wiederholt sich so oft, bis die Speicherschicht den offenzelligen Schaumkunststoff nicht mehr mit Kapillarwasser füllen kann.Starting from a floor covering of the type mentioned at the outset, this object can be achieved according to the invention in that a water reservoir and a layer are provided below the carrier web, the latter accomplishing the return transport of the water from the water reservoir into the upper regions of the floor covering during use of the floor covering. In particular, in order to achieve the object, it is proposed to form the plastic layer of an open-cell foam plastic (for example latex foams, polyurethane foam, foam rubber or the like) in a floor covering web of the type mentioned at the beginning, and a storage layer (for example nonwoven fabrics, Needle felts, heavy fabrics, open-cell foams or the like) with water-storing properties. In the event of rain or a moistening of the floor covering on its upper side, water enters the open-cell foam plastic layer through the openings in the carrier web and from there reaches the storage layer due to the force of gravity and / or a capillary action, which absorbs the water until their storage volume is exhausted; Water that can no longer be stored and accumulates on the surface of the covering emerges from the floor covering downwards through the storage layer and is drained into the substructure or flows laterally on the surface of a water-impermeable substructure. After the rain or the raining of the floor covering, the surface dries z. B. from sun and wind relatively quickly, but when playing the floor covering according to the invention, the open-cell foam plastic is compressed by pressure on the surface of the surface (z. B. by the foot of a player) and thereby the surface of the surface slightly moistened again, so that the desired The sliding effect is restored by a water film (pump and play system). This process is repeated until the storage layer can no longer fill the open-cell foam plastic with capillary water.
Versuche an einer mit dem erfindungsgemäßen Bodenbelag beleg¬ ten Sportfläche haben in den Sommermonaten bei mitteleuropä¬ ischem Klima gezeigt, daß der erfindungsgemäße Bodenbelag nach einmaligem Bewässern einen ganzen Tag bespielbar bleibt, d. h. die erwünschten Bespieleigenschaften beibehält. Im Ver¬ gleich zu herkömmlichen Bodenbelägen erfordert der erfin¬ dungsgemäße Bodenbelag nur ein Drittel bis ein Viertel des sonst erforderlichen Bewässerungswassers, um die gleichen spieltechnischen Eigenschaften wie bei den bekannten Bodenbe¬ lägen herbeizuführen. Bei der Speicherschicht kann es sich gleichfalls um eine offenzellige Schaumkunststoffschicht handeln, weshalb bei einer erfindungsgemäßen Bodenbelagsbahn die die Rückpumpwir¬ kung bewerkstelligende Schaumkunststoffschicht und die Spei¬ cherschicht von derselben Art sein und sogar eine einzige Schicht bilden können. Bei bevorzugten Ausführungs ormen des erfindungsgemäßen Bodenbelags wird die Speicherschicht jedoch von einem Faservlies gebildet, welches ein Mehrfaches seines eigenen Gewichts an Wasser adhäsiv speichern kann. Bevorzugt werden dabei Faservliese aus einem nicht-verrottendem Mate¬ rial, was im übrigen natürlich für alle Elemente des erfin¬ dungsgemäßen Bodenbelags gilt.Experiments on a sports area covered with the floor covering according to the invention have shown in the summer months in a central European climate that the floor covering according to the invention remains playable for a whole day after being watered once, ie maintains the desired playing properties. Compared to conventional floor coverings, the floor covering according to the invention requires only a third to a quarter of the irrigation water which is otherwise required in order to bring about the same technical playing properties as in the known floor coverings. The storage layer can likewise be an open-cell foam plastic layer, which is why, in the case of a floor covering web according to the invention, the foam plastic layer which brings about the pumping back effect and the storage layer can be of the same type and can even form a single layer. In preferred embodiments of the floor covering according to the invention, however, the storage layer is formed by a nonwoven fabric, which can adhesively store several times its own weight in water. Preference is given to nonwoven fabrics made from a non-rotting material, which of course also applies to all elements of the floor covering according to the invention.
Wie bei bekannten Bodenbelägen weisen auch bei bevorzugten Ausführungsformen des erfindungsgemäßen Bodenbelags die Pol¬ elemente auf der Trägerbahnunterseite angeordnete Veranke¬ rungsfüße auf, wobei es besonders vorteilhaft ist, wenn diese zwischen der Trägerbahn und der Schaumkunststoffschicht lie¬ gen; auf diese Weise dient die an die Rückseite der Träger¬ bahn insbesondere ankaschierte Schaumkunststoffschicht der Verbesserung der Fixierung der Polemente in der Trägerbahn, und die Verankerungsfüße der Polelemente werden durch die Schaumkunststoffschicht und die Speicherschicht abgedeckt, so daß sie beim Verlegen des Bodenbelags auf einem rauhen Unter¬ grund nicht der Gefahr unterliegen, infolge des Bespielens des Bodenbelags durchgescheuert zu werden.As with known floor coverings, in preferred embodiments of the floor covering according to the invention the pole elements have anchoring feet arranged on the underside of the carrier web, it being particularly advantageous if these lie between the carrier web and the foam plastic layer; In this way, the foam plastic layer, in particular laminated to the back of the support sheet, serves to improve the fixation of the pole elements in the support sheet, and the anchoring feet of the pole elements are covered by the foam plastic layer and the storage layer, so that when the floor covering is laid on a rough base ¬ not subject to the risk of being worn out due to the floor covering being used.
Als Kunststoff für die den Rückpumpeffekt bewerkstelligende Schaumkunststoffschicht wird insbesondere Butadienstyrol empfohlen; um einen einfach und vollständig recyclebaren Bodenbelag zu erhalten, bestehen bei anderen bevorzugten Aus¬ führungsformen des erfindungsgemäßen Bodenbelags jedoch Trä¬ gerbahn, Polelemente, Schaumkunststoffschicht und Speicher¬ schicht aus demselben Kunststoff. Wie bereits erwähnt, empfiehlt es sich, die den Rückpump¬ effekt bewerkstelligende offenzellige Schaumkunststoffschicht und die Speicherschicht an die Rückseite der Trägerbahn anzu- kaschieren, wobei durch die Art des Ankaschierens, insbeson¬ dere durch ein entsprechend gewähltes Muster einer Verbin¬ dungsschicht, jedoch gewährleistet werden muß, daß an der Be¬ lagsoberfläche anfallendes Wasser durch die Trägerbahn, die Schaumkunststoffschicht und die Speicherschicht hindurchtre¬ ten kann.In particular, butadiene styrene is recommended as the plastic for the foam pumping layer which brings about the return pump effect; In order to obtain a floor covering that is simple and completely recyclable, in other preferred embodiments of the floor covering according to the invention, however, the carrier sheet, pole elements, foam plastic layer and storage layer consist of the same plastic. As already mentioned, it is advisable to laminate the open-cell foam plastic layer which brings about the pump-back effect and the storage layer to the back of the carrier web, whereby, however, the type of lamination, in particular by a correspondingly chosen pattern of a connecting layer, ensures It must be ensured that water accumulating on the covering surface can pass through the carrier web, the foam plastic layer and the storage layer.
Weitere Merkmale, Vorteile und- Einzelheiten der Erfindung er¬ geben sich aus der beigefügten schematischen zeichnerischen Darstellung und der nachfolgenden Beschreibung einer beson¬ ders bevorzugten Ausführungsform eines erfindungsgemäßen Bodenbelags; die Zeichnung zeigt einen Schnitt durch den als Tuftingware ausgebildeten Bodenbelag.Further features, advantages and details of the invention emerge from the attached schematic drawing and the following description of a particularly preferred embodiment of a floor covering according to the invention; the drawing shows a section through the tufted floor covering.
Die Zeichnung zeigt eine Trägerbahn 10, bei der es sich um eine Tuftinggrundware handelt, insbesondere um ein Gewebe aus Kunststoffbändchen. In dieser sind Polelemente 12 verankert, welche durch Tuften in die Trägerbahn 10 eingebracht wurden und von Kunststoffbändchen gebildet werden. Sie sind in der Seitenansicht ungefähr U-förmig ausgebildet und bilden an der Unterseite der Trägerbahn jeweils einen Verankerungsfuß 12a.The drawing shows a carrier web 10, which is a basic tufting product, in particular a fabric made of plastic tapes. Pole elements 12 are anchored in this, which were introduced into the carrier web 10 by tufts and are formed by plastic tapes. In side view, they are approximately U-shaped and each form an anchoring foot 12a on the underside of the carrier web.
An die Unterseite der Tuftingware 10, 12 ist eine Schaum¬ kunststoffschicht 14 ankaschiert, die aus einem offenzelligem Schaumkunststoff besteht und erfindungsgemäß dickenelastisch ist. Schließlich ist an die Unterseite der Schaumkunst¬ stoffschicht 14 eine Faservliesschicht 16 ankaschiert, welche die erfindungsgemäße Wasserspeicherschicht bildet. Durch die Dicke, Dichte, Struktur und die Art des Fasermaterials der Faservliesschicht 16 läßt sich die erwünschte Speicherkapazi¬ tät erreichen und einstellen. Die Poren der Schaumkunststoffschicht 14 ermöglichen einen durch die Schwerkraft bewirkten Wassertransport durch die Schaumkunststoffschicht 14 hindurch in die Faservlies- schicht 16 und infolge der Kapillarwirkung bzw. der beim Be¬ spielen des Bodenbelags auftretenden Pumpwirkung aus der Faservliesschicht 16 zurück in die eigentliche Kunstrasen¬ schicht 10, 12 und insbesondere durch deren wasserdurchläs¬ sige Trägerbahn 10 hindurch an die Oberfläche der Kunstrasen¬ schicht. Zur Wasserdurchlässigkeit der Trägerbahn 10 ist noch zu bemerken, daß diese in vielfältiger Weise gewährleistet und eingestellt werden kann, so z. B. durch verhältnismäßig dicke Nadeln beim'Tuften, durch die Art und Dichte des für die Herstellung der Trägerbahn 10 verwendeten textilen Mate¬ rials, z. B. also durch die Breite der für die Herstellung eines Gewebes verwendeten Kunststoffbändchen und die Abstände zwischen den von den Bändchen gebildeten Kett- und Schußfäden voneinander sowie durch die Art einer eventuell eingesetzten Ausrüstung des Trägerbahnmaterials; hierbei handelt es sich jedoch um bekannte Maßnahmen, so daß es einer detaillierten Erläuterung derselben nicht bedarf. A foam plastic layer 14 is laminated onto the underside of the tufted goods 10, 12, which layer consists of an open-cell foam plastic and is, according to the invention, elastic in thickness. Finally, a fiber fleece layer 16 is laminated to the underside of the foam plastic layer 14, which layer forms the water storage layer according to the invention. The desired storage capacity can be achieved and set by the thickness, density, structure and type of fiber material of the nonwoven layer 16. The pores of the foam plastic layer 14 enable water to be transported by gravity through the foam plastic layer 14 into the fiber fleece layer 16 and as a result of the capillary action or the pumping action from the fiber fleece layer 16 occurring when the floor covering is used, back into the actual artificial turf layer 10 , 12 and in particular through their water-permeable carrier web 10 to the surface of the artificial turf layer. Regarding the water permeability of the carrier web 10, it should also be noted that this can be ensured and adjusted in a variety of ways, for. B. by relatively thick needles in tufting, by the type and density of the textile material used for the production of the carrier web 10, e.g. B. thus by the width of the plastic ribbons used for the production of a fabric and the distances between the warp and weft threads formed by the ribbons from each other and by the type of equipment used for the carrier web material; however, these are known measures, so that a detailed explanation of them is not required.
