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

Bodenbelag, insbesondere Sportplatzbelag Floor covering, in particular sports field covering
Die Erfindung betrifft einen Bodenbelag auf der Grundlage eines elastischen Kunststoffs, mit einer im wesentlichen ebenen und begehbaren Oberseite und einer im Abstand zu dieser angeordneten Unterseite.The invention relates to a floor covering on the basis of an elastic plastic, with an essentially flat and walkable top and a bottom arranged at a distance from this.
Für Sportanlagen sind solche Beläge als Granulatbeläge, Massivkunststoffbeläge oder sogenannte Sandwichbeläge be¬ kannt. Solche Beläge enthalten elastische Kunstharzparti¬ kel, die mit einem elastischen Kunstharzbindemittel gebun¬ den 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 Lauf¬ sport, da sie in Folge ihrer Elastizität beim Laufen dämp¬ fend sind und Ueberbeanspruchungen insbesondere der Gelenke mindern. Die Oberfläche ist in Folge vorstehender Kunst¬ harzpartikel uneben und erlaubt eine gut Haftung des Lauf¬ schuhs beim Abstossen. Auf diesen Belägen sind deshalb auf der Kurz- und Mitteldistanz hervorragende Laufzeiten er¬ zielt worden.The above-mentioned pads 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 the short and medium distances.
Der Erfinder hat sich nun die Aufgabe gestellt, einen Bo¬ denbelag der genannten Gattung zu schaffen, der noch kürze¬ re Laufzeiten fördert und der trotzdem dauerhaft ist und kostengünstig hergestellt werden kann. Die Aufgabe ist bei einem gattungsgemässen Bodenbelag dadurch gelöst, dass er bezüglich seiner Elastizität in der vorgesehenen Laufrich¬ tung anisotrop ist, derart, dass er einen etwa in Laufrich¬ tung auf die Oberseite einwirkenden Laufschuh stärker dämpft als einen etwa in der Gegenrichtung auf die Obersei¬ te einwirkenden Laufschuh.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 in the case of a generic floor covering in that it is anisotropic with regard to its elasticity in the direction of travel provided, in such a way that it dampens a running shoe acting approximately in the direction of travel on the upper side more than one in the opposite direction on the upper side ¬ te acting running shoe.
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 besse¬ ren 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 rea¬ lisieren, wenn in den genannten elastischen Kunststoff ein Netz oder ein Gewebe oder dergleichen eingesetzt ist, das mindestens bereichsweise eine geringere Elastizität auf¬ weist 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 Längs¬ richtung gebogen und üben dadurch nur eine sehr geringe Ge¬ genkraft aus. Bei einer entsprechenden Krafteinwirkung in Gegenrichtung werden diese Nocken oder Zapfen in ihrer Längsrichtung beansprucht und bieten dadurch einen wesent¬ lich höheren entgegenwirkenden Widerstand gegen eine Defor¬ mation. In dieser Richtung erfährt entsprechend der Läufer einen höheren Widerstand und entsprechend eine geringere Dämpfung. Ein solches Gewebe ist vorzugsweise aus syntheti¬ schem oder natürlichem Kautschuk hergestellt. Der die Grundlage bildende elastische Kunststoff ist dann vorzugs¬ weise ein Elastomer, beispielsweise Polyurethan.The invention can be implemented particularly cost-effectively if a mesh or a fabric or the like is used in the elastic plastic mentioned, which at least in some areas has a lower elasticity than said elastic plastic and this net or fabric has cams, pins or the like inclined in the running direction mentioned. 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 low counterforce. With a corresponding action of force in the opposite direction, these cams or pins are stressed in their longitudinal direction and thereby 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 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, insbeson¬ dere auf einen Sportplatz, hergestellt werden. Das Netz oder das Gewebe kann dann auf der vorbereiteten ebenen Un¬ terlage beispielsweise mittels eines Klebers befestigt wer¬ den. Anschliessend wird beispielsweise Polyurethan aufge¬ gossen, 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 mesh or the 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 Darstellungsgrün¬ den in einem wesentlich kleineren Massstab dargestellt ist als der Belag 1. Der Belag 1 ruht auf einer an sich belie¬ bigen 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 direction of travel 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 webs or can 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 we¬ sentlichen aus einer KlebstoffSchicht 4, einer Schicht 2 aus einem elastischen Kunststoff, beispielsweise Polyuret¬ han 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 Ä gegenüber der Vertikalen ge¬ neigt sind. Dieser Winkel Ä beträgt beispielsweise 30°, je¬ doch sind wesentliche Abweichungen davon möglich. Die LängeThe 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 of an elastic plastic, for example polyurethane, and a mesh 3 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 multiplicity of cams or pins 3b which are inclined in the same direction at an angle A with respect to the vertical. This angle Ä is, for example, 30 °, but substantial deviations from this are possible. The length
I (Fig. 3) der Zapfen oder Nocken 3b beträgt beispielsweiseI (Fig. 3) of the pin or cam 3b is, for example
II mm. Sie können gemäss Fig. 11 oben vorstehend sein. Die Zapfen oder Nocken 3b sind durch Stege 3c miteinander ver¬ bunden. 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 Zap¬ fen 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 Zap¬ fen 3b steiler als im übrigen Bereich anzuordnen.II mm. 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 network 3 is thus fixed by the adhesive 4 and by the elastic plastic 2. Embodiments are also conceivable in which the pins or cams 3b are not directed upwards but, as shown in FIG. 10, downwards. 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 Untergrun¬ des 5 wird auf diesem eine gleichmässige Schicht 4 aus ei¬ nem 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 Unter¬ grund 5 fixiert wird. Anschliessend wird zur Bildung der Schicht 2 auf das fixierte Netz 3 ein geeigneter elasti¬ scher 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 fi¬ xiert und mit dieser verbunden. Die Herstellung kann ver¬ gleichsweise 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. 1. After the preparation of the base 5, a uniform layer 4 of a suitable adhesive is applied to it. 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 erfin- dungsgemässen 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 Bela¬ ges 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 bie- ten, 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 be¬ lastet. In dieser können die Zapfen oder Nocken 3b jedoch nur wenig nachgeben, so dass diese beim Abstoss gemäss Fig.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 base 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 ten, the rebound 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 region 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 when they are pushed off according to FIG.
8 hart sind und somit die Dämpfungseigenschaften des Bela¬ ges 1 in dieser Richtung wesentlich mindern. Der Abstoss kann somit gegen einen in dieser Richtung wesentlich weni¬ ger elastischen Belag erfolgen und ist entsprechend für die Fortbewegung wirksamer.8 are hard and thus significantly reduce the damping properties of the covering 1 in this direction. The push-off can thus take place against a covering which is substantially 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.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.

Das Gewebe 12 kann ein synthetisches Gewebe sein, beispielsweise ein Polyestergewebe. 9 an embodiment, * in which in a resilient plastic material 11 is an apertured web 12 is embedded, which, as shown here in the running direction 6 has a wavy course. The fabric 12 can be a synthetic fabric, for example a polyester fabric.
