Date Jul. 27, 1995A floor covering, in particular for sport fields, based on elastic plastics, has a substantially flat top side on which one can walk and a bottom side spaced apart therefrom. The covering has an anisotropic elasticity in the desired running direction, so that it dampens more strongly the impact of a shoe of a runner running on the top side in the desired direction than the impact of the shoe of a runner running on the top side in the opposite direction.

Description

Die Erfindung betrifft einen Bodenbelag nach dem Oberbegriff des Anspruchs 1. Die Erfindung betrifft zudem ein Verfahren zu Herstellung dieses Bodenbelags.The invention relates to a floor covering according to the preamble of claim 1. The invention also relates to a method for producing this floor covering.

Für Sportanlagen sind solche Beläge als Granulatbeläge, Massivkunststoffbeläge oder sogenannte Sandwichbeläge bekannt. Solche Beläge enthalten elastische Kunstharzpartikel, die mit einem elastischen Kunstharzbindemittel gebunden sind. Insbesondere aus Kostengründen sind in der Regel Altgummipartikel oder dergleichen beigemischt.For sports facilities, such coverings are known as granulate coverings, solid plastic coverings or so-called sandwich coverings. Such coverings contain elastic synthetic resin particles which are bound with an elastic synthetic resin binder. For reasons of cost in particular, waste rubber particles or the like are generally added.

Die genannten Beläge eignen sich insbesondere für den Laufsport, da sie in Folge ihrer Elastizität beim Laufen dämpfend sind und Ueberbeanspruchungen insbesondere der Gelenke mindern. Die Oberfläche ist in Folge vorstehender Kunstharzpartikel uneben und erlaubt eine gut Haftung des Laufschuhs beim Abstossen. Auf diesen Belägen sind deshalb auf der Kurz- und Mitteldistanz hervorragende Laufzeiten erzielt worden.The above-mentioned rubbers are particularly suitable for running, since their elasticity makes them damp when running, and they put excessive strain on the joints in particular reduce. As a result of the above synthetic resin particles, the surface is uneven and allows the running shoe to adhere well when pushed off. Excellent running times have therefore been achieved on these coverings over short and medium distances.

Aus der DE-C-33 39 553 ist ein Bodenbelag für Tennisplätze bekannt geworden, dessen Oberseite so beschaffen ist, dass beim Starten zum Netz hin der Fuss des Tennisspielers eine sichere Abstützung erfährt. Beim Bremsen ergibt sich bei diesem Belag hingegen das gewünschte Rutschen in Richtung auf das Netz. Nahe unterseitig angeordneter Vertiefungen verläuft im Bodenbelag ein textiles Gewebe oder Netz, das als Verstärkungseinlage dienen soll. Für die Leichtathletik und insbesondere für den Laufsport eignet sich ein solcher Belag selbstverständlich nicht.From DE-C-33 39 553 a floor covering for tennis courts has become known, the top of which is such that the tennis player's foot experiences a secure support when starting towards the net. When braking, on the other hand, the desired slippage in the direction of the net results. A textile fabric or net runs in the floor covering near the underside and is intended to serve as a reinforcement insert. Such a surface is of course not suitable for athletics and especially for running.

Der Erfinder hat sich nun die Aufgabe gestellt, einen Bodenbelag der genannten Gattung zu schaffen, der noch kürzere Laufzeiten fördert und der trotzdem dauerhaft ist und kostengünstig hergestellt werden kann. Die Aufgabe ist gemäss Anspruch 1 gelöst.The inventor has now set himself the task of creating a floor covering of the type mentioned, which promotes even shorter running times and which is nevertheless durable and can be produced inexpensively. The object is achieved according to claim 1.

Durch die richtungsabhängigen Dämpfungseigenschaften ist es möglich, einen Sportplatzbelag so auszubilden, dass er für den Läufer beim Abstossen wesentlich härter ist als beim Abbremsen nach der Flugphase. Dies ermöglicht einen besseren Vortrieb bei gleichen Dämpfungswirkungen am Ende der Flugphase. Der erfindungsgemässe Bodenbelag eignet sich auch als Industriebodenbelag, beispielsweise für Rampen und Rolltreppen sowie Fahrwegen mit Steigung.The direction-dependent damping properties make it possible to design a sports field surface so that it is much harder for the runner when pushing off than when braking after the flight phase. This enables better propulsion with the same damping effects at the end of the flight phase. The floor covering according to the invention is also suitable as an industrial floor covering, for example for ramps and escalators and driving paths with a slope.

Die Erfindung lässt sich dann besonders kostengünstig realisieren, wenn in den genannten elastischen Kunststoff ein Netz oder ein Gewebe oder dergleichen eingesetzt ist, das mindestens bereichsweise eine geringere Elastizität aufweist als der genannte elastische Kunststoff und dieses Netz oder Gewebe in der genannten Laufrichtung geneigte Nocken, Zapfen oder dergleichen aufweist. Bei einer etwa in Laufrichtung auf die Oberseite des Belages einwirkenden Kraft werden diese Nocken oder Zapfen quer zu ihrer Längsrichtung gebogen und üben dadurch nur eine sehr geringe Gegenkraft aus. Bei einer entsprechenden Krafteinwirkung in Gegenrichtung werden diese Nocken oder Zapfen in ihrer Längsrichtung beansprucht und bieten dadurch einen wesentlich höheren entgegenwirkenden Widerstand gegen eine Deformation. In dieser Richtung erfährt entsprechend der Läufer einen höheren Widerstand und entsprechend eine geringere Dämpfung. Ein solches Gewebe ist vorzugsweise aus synthetischem oder natürlichem Kautschuk hergestellt. Der die Grundlage bildende elastische Kunststoff ist dann vorzugsweise ein Elastomer, beispielsweise Polyurethan.The invention can be implemented particularly inexpensively if a mesh or a fabric or the like is used in the elastic plastic mentioned, which has at least in some areas a lower elasticity than the elastic plastic mentioned and this mesh or fabric inclined cams, pins in the direction of travel or the like. In the event of a force acting in the running direction on the upper side of the covering, these cams or pins are bent transversely to their longitudinal direction and therefore exert only a very slight counterforce. With a corresponding force in the opposite direction, these cams or pins are stressed in their longitudinal direction and thus offer a substantially higher counteracting resistance to deformation. In this direction, the rotor experiences a higher resistance and a correspondingly lower damping. Such a fabric is preferably made of synthetic or natural rubber. The the Elastic plastic forming the basis is then preferably an elastomer, for example polyurethane.

Der erfindungsgemässe Bodenbelag kann aus vorgefertigten Platten oder Bahnen oder direkt durch Aufgiessen, insbesondere auf einen Sportplatz, hergestellt werden. Das Netz oder das Gewebe kann dann auf der vorbereiteten ebenen Unterlage beispielsweise mittels eines Klebers befestigt werden. Anschliessend wird beispielsweise Polyurethan aufgegossen, bis die Nocken bzw. Zapfen überdeckt sind.The floor covering according to the invention can be produced from prefabricated panels or sheets or directly by pouring, in particular onto a sports field. The net or fabric can then be attached to the prepared flat base, for example by means of an adhesive. Then, for example, polyurethane is poured on until the cams or pins are covered.

Die Fig. 1 zeigt einen Belag 1 mit einer Oberseite 1a und einer dazu parallelen im wesentlichen ebenen Unterseite 1b. Die Laufrichtung ist durch den Pfeil 6 angegeben und durch einen Läufer 14 veranschaulicht, der aus Darstellungsgründen in einem wesentlich kleineren Massstab dargestellt ist als der Belag 1. Der Belag 1 ruht auf einer an sich beliebigen ebenen Unterlage 5. Der Belag 1 kann aus einzelnen Platten oder Bahnen bestehen oder in einem Guss hergestellt sein.1 shows a covering 1 with an upper side 1a and an essentially flat lower side 1b parallel thereto. The running direction is indicated by arrow 6 and illustrated by a rotor 14, which is shown on a much smaller scale for reasons of illustration as the covering 1. The covering 1 rests on a flat base 5 which is in itself arbitrary. The covering 1 can consist of individual plates or sheets or be produced in one casting.

Der Abstand h zwischen der Oberseite 1a und der Unterseite 1b liegt vorzugsweise in einem Bereich von 0,5 bis 3 cm und beträgt vorzugsweise etwa 1 cm. Der Belag 1 besteht im wesentlichen aus einer Klebstoffschicht 4, einer Schicht 2 aus einem elastischen Kunststoff, beispielsweise Polyurethan sowie einem in die Schicht 2 eingebetteten Netz 3 aus synthetischem oder natürlichem Kautschuk. Die Elastizität der Schicht 2 ist grösser, vorzugsweise wesentlich grösser als diejenige des Netzes 3. In den Figuren 2 und 3 ist das Netz 3 näher dargestellt. Wie ersichtlich, weist es eine Vielzahl von Nocken oder Zapfen 3b auf, die in gleicher Richtung mit einem Winkel  gegenüber der Vertikalen geneigt sind. Dieser Winkel  beträgt beispielsweise 30°, jedoch sind wesentliche Abweichungen davon möglich. Die Länge l (Fig. 3) der Zapfen oder Nocken 3b beträgt beispielsweise 11 mm. Sie können gemäss Fig. 11 oben vorstehend sein. Die Zapfen oder Nocken 3b sind durch Stege 3c miteinander verbunden. Zwischen den Stegen 3c weist das Netz 3 Durchbrüche auf, die vom Kleber 4 ausgefüllt sind. Das Netz 3 ist somit durch den Kleber 4 sowie durch den elastischen Kunststoff 2 fixiert. Denkbar sind auch Ausführungen, bei denen die Zapfen oder Nocken 3b nicht nach oben, sondern gemäss Fig. 10 nach unten gerichtet sind. Die Neigungen der Nocken oder Zapfen 3b können bei einem Bodenbelag in Anpassung an die jeweiligen Anforderungen unterschiedlich sein. Bei einem Bodenbelag für eine Hochsprunganlage ist es beispielsweise zweckmässig, im Bereich des Absprungs die Nocken oder Zapfen 3b steiler als im übrigen Bereich anzuordnen.The distance h between the top 1a and the bottom 1b is preferably in a range from 0.5 to 3 cm and is preferably about 1 cm. The covering 1 essentially consists of an adhesive layer 4, a layer 2 made of an elastic plastic, for example polyurethane, and a mesh 3 made of synthetic or natural rubber embedded in the layer 2. The elasticity of layer 2 is greater, preferably significantly greater than that of network 3. Network 3 is shown in more detail in FIGS. 2 and 3. As can be seen, it has a plurality of cams or pins 3b which are inclined in the same direction at an angle einem with respect to the vertical. This angle  is, for example, 30 °, but significant deviations from this are possible. The length l (FIG. 3) of the pins or cams 3b is 11 mm, for example. You can be above according to FIG. 11 above. The pins or cams 3b are connected to one another by webs 3c. Between the webs 3c, the network 3 has openings which are filled with the adhesive 4. The net 3 is thus fixed by the adhesive 4 and by the elastic plastic 2. Designs are also conceivable in which the pins or cams 3b are not directed upwards, but rather downwards according to FIG. The inclinations of the cams or pins 3b can be adapted to the floor covering different requirements. In the case of a floor covering for a high jump system, it is expedient, for example, to arrange the cams or pins 3b in the area of the jump more steeply than in the rest of the area.

Die Figuren 4 bis 6 zeigen schematisch die Herstellung des Belages gemäss Fig. 1. Nach der Vorbereitung des Untergrundes 5 wird auf diesem eine gleichmässige Schicht 4 aus einem geeigneten Klebstoff aufgebracht. Auf die Schicht 4 wird das Netz 3 gelegt, so dass der Kleber der Schicht 4 in die Durchbrüche 3b einfliesst und das Netz 3 auf dem Untergrund 5 fixiert wird. Anschliessend wird zur Bildung der Schicht 2 auf das fixierte Netz 3 ein geeigneter elastischer Kunststoff, vorzugsweise Polyurethan aufgegossen und verteilt. Nach dem Aushärten der Schicht 2 sind die Zapfen oder Nocken 3b wie in Fig. 6 gezeigt in der Schicht 2 fixiert und mit dieser verbunden. Die Herstellung kann vergleichsweise einfach direkt auf der Sportanlage erfolgen oder es können einzelne Platten oder teppichartige Beläge vorgefertigt werden.FIGS. 4 to 6 show schematically the production of the covering according to FIG. The mesh 3 is placed on the layer 4, so that the adhesive of the layer 4 flows into the openings 3b and the mesh 3 is fixed on the substrate 5. A suitable elastic plastic, preferably polyurethane, is then poured on and distributed to form the layer 2 on the fixed net 3. After the layer 2 has hardened, the pins or cams 3b are fixed in the layer 2 as shown in FIG. 6 and connected to the latter. The production can be carried out comparatively simply directly on the sports facility or individual plates or carpet-like coverings can be prefabricated.

Die Figuren 7 und 8 verdeutlichen die Wirkung des erfindungsgemässen Sportbelages. Die Fig. 7 zeigt einen Fuss 8 des Läufers 14, der am Ende einer Flugphase mit dem Absatz 8a in Richtung des Pfeiles 7 auf die Oberseite 1a des Belages 1 auftritt. Durch die auf den Belag 1 einwirkende Kraft wird dieser wie gezeigt deformiert, wobei die Zapfen oder Nocken 3b mehr oder weniger gebogen werden. Da hier die Zapfen oder Nocken 3b keinen wesentlichen Widerstand bieten, wird der Aufstoss der Fusses 8 gedämpft, der Belag 1 ist somit in Richtung des Pfeiles 7 elastisch. Beim Abstoss und somit zu Beginn einer neuen Flugphase übt der Fuss 8 im Zehenbereich 8b eine nach rückwärts gerichtete Kraft aus, wie dies in Fig. 1 gezeigt ist. Durch die Abstosskraft werden die Zapfen oder Nocken 3b in ihrer Längsrichtung belastet. In dieser können die Zapfen oder Nocken 3b jedoch nur wenig nachgeben, so dass diese beim Abstoss gemäss Fig. 8 hart sind und somit die Dämpfungseigenschaften des Belages 1 in dieser Richtung wesentlich mindern. Der Abstoss kann somit gegen einen in dieser Richtung wesentlich weniger elastischen Belag erfolgen und ist entsprechend für die Fortbewegung wirksamer.Figures 7 and 8 illustrate the effect of the sports surface according to the invention. FIG. 7 shows a foot 8 of the runner 14, which occurs at the end of a flight phase with the step 8a in the direction of the arrow 7 on the upper side 1a of the covering 1. As a result of the force acting on the covering 1, the covering 1 is deformed, the pins or cams 3b being more or less bent. Since the pins or cams 3b do not offer any significant resistance here, the impact of the foot 8 is damped, the covering 1 is thus elastic in the direction of arrow 7. When pushing off and thus at the beginning of a new flight phase, the foot 8 exerts a rearward force in the toe area 8b, as shown in FIG. 1. The pins or cams 3b are loaded in their longitudinal direction by the repulsive force. In this, however, the pins or cams 3b can yield only slightly, so that they are hard when repelled according to FIG. 8 and thus significantly reduce the damping properties of the covering 1 in this direction. The push-off can thus take place against a covering that is significantly less elastic in this direction and is accordingly more effective for locomotion.

Für den Fachmann ist es klar, dass die für die Erfindung wesentliche Anisotropie des Belages 1 auf unterschiedliche Weise realisiert werden kann. Beispielsweise zeigt die Fig. 9 eine Ausführung, bei der in einem elastischen Kunststoff 11 ein appretiertes Gewebe 12 eingebettet ist, das wie hier gezeigt in der Laufrichtung 6 einen wellenförmigen Verlauf aufweist. Das Gewebe 12 kann ein synthetisches Gewebe sein, beispielsweise ein Polyestergewebe.It is clear to the person skilled in the art that the anisotropy of the covering 1 which is essential for the invention can be realized in different ways. For example, FIG. 9 shows an embodiment in which a finished fabric 12 is embedded in an elastic plastic 11 and, as shown here, has a wavy course in the running direction 6. The fabric 12 can be a synthetic fabric, for example a polyester fabric.
