Definitions
- the invention relates to a tennis floor, which is built up from a flat, web-shaped material and a grain mixture or granules.
- DE-OS 20 39 506 describes a sports floor covering or nonwoven for outdoor sports facilities, which has a surface made of fibers on its surface, which is additionally consolidated by rubber or plastic binders.
- the braking properties of such a fleece are in need of improvement for tennis.
- the player can slip too much or slow down too much.
- a possible disadvantage for the athlete is to be compensated for by choosing suitable sports shoes, and a rubber or plastic binder is used, which would lead to an extraordinary odor nuisance when used on indoor courts.
- DE-OS 26 52 557 describes a playing surface layer arrangement for athletic games such as tennis.
- This known arrangement has upward-facing knobs made of plastic, which are designed as single threads or as tufts and between which mineral grains are contained.
- This floor has the disadvantage that the mineral grains filled in soon destroy the knob elements, which is caused by the friction when the floor is covered so that they can no longer fulfill their task. With this structure, there is a strong sanding effect of the mineral grains among one another and to the fiber material, combined with a considerable amount of dust.
- DE-OS 28 26 206 describes a covering for sports fields, in particular tennis courts, in which a solid rubber granulate is applied to a solid floor surface, for example made of asphalt, concrete, wood or other materials, then through a layer of fine rubber particles is covered.
- a solid rubber granulate is applied to a solid floor surface, for example made of asphalt, concrete, wood or other materials, then through a layer of fine rubber particles is covered.
- the maintenance of such a floor is relatively complex because, when the upper surface is stressed, the rubber particles move in such a way that the desired sliding and braking effect in the relevant surface areas is no longer or not changed.
- the fleece has the disadvantage that the original surface is destroyed after a short period of use by the considerable thrust forces that are transferred to it during tennis play. Due to the loose top processing of the yarn, the fiber wears out quickly.
- the invention has for its object to provide a tennis flooring so that the use of the structure of the fiber is retained, the required braking and sliding effect occurs when the floor is used and the surface can be maintained cheap.
- a covering material with at least one structured top made of fibers in which a lot of granular material is sprinkled.
- the covering material is preferably a structured needle fleece made of synthetic fibers. Instead of a needle fleece, an appropriately structured tufting product can also be used with great success.
- the structuring should result in elevations and depressions in regular patterns that cover the surface of the covering material, for example in the form of ribs.
- the fleece receives a pattern. The result is fiber zones that are lower and those that are higher, giving the player a firm grip and thus a good start to the ball.
- the structuring allows a solid material, for example fleece, which pellets in particular in the wells, but also in higher lying zones.
- the pattern can be waffle-like or rib-like; the high and low areas are decisive.
- the cork granulate is a grain size of up to approximately 3 mm ⁇ , preferably a grain size of 0.5-2.5 mm.
- the recesses form quasi depots for the grain and also ensure a constant distribution of the granulate over the entire surface. Sliding and braking zones are balanced, i.e. the result is a tennis floor with a surface with homogeneous properties.
- the granulate is elastic in order to give the covering a corresponding vertical elasticity. It is resistant to prevent the granulate parts from being ground quickly.
- the granulate is also no harder than the fiber, so that it protects the fiber more than it wears out.
- Covering material other than needle-punched nonwovens is often also advantageous because needle-punched nonwovens can contain considerable winding tensions after the webs are rolled up and are therefore difficult to lay on adhesive tapes. It is also not suitable for self-adhesive back coatings that are necessary for renovation projects if you want to relocate to existing tennis surfaces.
- reference numeral 1 denotes the sheet-like covering material e.g. a needle fleece or a corresponding tufted fabric.
- the structure of the covering results from rib-like elevations 2 and depressions 3.
- the applied cork granulate 4 collects in the depressions 3, which act like deposits.
- Fine-grained granulate 5 is also located between the fibers of the elevations 2.
- the surface of the covering material is of course not film-smooth but fibrous rough.
- the depressions 3 and the elevations 2 lie relatively close together, so that the amount of granules to be applied does not become too large.
- the width of a depression 3 and an elevation 2 should not exceed 5-6 mm, and the depth of the depressions 3 should not exceed 5 mm.

Abstract
Description
Die Erfindung bezieht sich auf einen Tennisboden, der sich aus einem flächigen, bahnförmigen Material und einem Korngemisch oder einem Granulat aufbaut.The invention relates to a tennis floor, which is built up from a flat, web-shaped material and a grain mixture or granules.
In der DE-OS 20 39 506 wird eine Sportbodenbelagsbahn oder -vlies für Freiluftsportstätten beschrieben, die an ihrer Oberfläche eine aus Fasern gebildete Trittoberschicht aufweist, die zusätzlich durch Kautschuk- oder Kunststoffbinder verfestigt ist. Die Bremseigenschaften eines solchen Vlieses sind für den Tennissport verbesserungsbedürftig. Je nach Fasermaterial kann der Spieler zu stark rutschen oder zu stark abgebremst werden. Bei der bekannten Sportbelagsbahn soll ein möglicher Nachteil für den Sportler durch Wahl geeigneter Sportschuhe ausgeglichen werden, zudem wird ein Kautschuk- oder Kunststoffbinder verwandt, der bei Verwendung auf Hallenplätzen zu einer außerordentlichen Geruchsbelästigung führen würde.DE-OS 20 39 506 describes a sports floor covering or nonwoven for outdoor sports facilities, which has a surface made of fibers on its surface, which is additionally consolidated by rubber or plastic binders. The braking properties of such a fleece are in need of improvement for tennis. Depending on the fiber material, the player can slip too much or slow down too much. In the known sports surface track, a possible disadvantage for the athlete is to be compensated for by choosing suitable sports shoes, and a rubber or plastic binder is used, which would lead to an extraordinary odor nuisance when used on indoor courts.
In der DE-OS 26 52 557 wird eine Spielflächen-Schichtanordnung für athletische Spiele, wie Tennis, beschrieben. Diese bekannte Anordnung weist aufwärtsgerichtete Noppen aus Kunststoff auf, die als Einzelfäden oder als Büschel ausgebildet sind und zwischen denen Mineralkörner enthalten sind. Dieser Boden hat den Nachteil, daß die eingefüllten Mineralkörner die Noppenelemente bald zerstören, was durch die Reibung erfolgt, wenn der Boden bespielt wird, so daß sie ihre Aufgabe nicht mehr erfüllen können. Bei diesem Aufbau tritt ein starker Schmirgeleffekt der Mineralkörner untereinander und zu dem Fasermaterial ein, verbunden mit einer erheblichen Staubentwicklung.DE-OS 26 52 557 describes a playing surface layer arrangement for athletic games such as tennis. This known arrangement has upward-facing knobs made of plastic, which are designed as single threads or as tufts and between which mineral grains are contained. This floor has the disadvantage that the mineral grains filled in soon destroy the knob elements, which is caused by the friction when the floor is covered so that they can no longer fulfill their task. With this structure, there is a strong sanding effect of the mineral grains among one another and to the fiber material, combined with a considerable amount of dust.
In der DE-OS 28 26 206 wird ein Belag für Sportplätze, insbesondere Tennisplätze, beschrieben, bei dem auf eine feste, beispielsweise aus Asphalt, Beton, Holz oder anderen Werkstoffen bestehende Bodenfläche ein verfestigtes Kautschukgranulat aufgebracht wird, dann durch eine Schicht aus feinen Gummiteilchen abgedeckt wird. Die Instandhaltung eines solchen Bodens ist verhältnismäßig aufwendig, weil bei Beanspruchung der Oberseite sich die Gummiteilchen so verschieben, daß der angestrebte Gleit- und Bremseffekt in den betreffenden Flächenbereichen nicht mehr bzw. nicht verändert gegeben ist.DE-OS 28 26 206 describes a covering for sports fields, in particular tennis courts, in which a solid rubber granulate is applied to a solid floor surface, for example made of asphalt, concrete, wood or other materials, then through a layer of fine rubber particles is covered. The maintenance of such a floor is relatively complex because, when the upper surface is stressed, the rubber particles move in such a way that the desired sliding and braking effect in the relevant surface areas is no longer or not changed.
Diese Konstruktion hat durch die Einstreuung von Gummiteilchen zudem den Nachteil, daß eine starke Belästigung durch den typischen Gummigeruch auftritt. Weiterhin sind die Gummiteilchen einem schnellen Verschleiß unterworfen. Auch die Auswirkungen, die durch das Einatmen der Staubteilchen entstehen können, sind ebenfalls nicht außer Acht zu lassen. Durch den schnellen Verschleiß der Gummiteilchen muß auch ständig neues Granulat nachgeführt werden, um eine ausreichende Roll- und Gleitschicht zu haben, was wiederum sehr pflegeintensiv und kostenträchtig ist. Schließlich wird in der P 31 29 837.0-25 ein Tennisbodenbelag beschrieben, der aus einer Nadelvliesbahn besteht, die offenfädig ausgebildet ist und in die im oberen Bereich ein Gummigranulat eingestreut ist.Due to the scattering of rubber particles, this construction also has the disadvantage that there is a strong nuisance due to the typical rubber smell. Furthermore, the rubber particles are subject to rapid wear. The effects of inhaling the dust particles should not be ignored either. Due to the rapid wear of the rubber particles, new granules also have to be constantly added in order to have a sufficient rolling and sliding layer, which in turn is very maintenance-intensive and costly. Finally, P 31 29 837.0-25 describes a tennis floor covering which consists of a needle-punched non-woven web which is open-thread and into which a rubber granulate is sprinkled in the upper area.
Neben den o.g. nachteiligen Eigenschaften des Gummigranulats, hat das Vlies durch die offenfädige Ausbildung den Nachteil, das nach kurzer Gebrauchszeit die ursprüngliche Oberfläche durch die erheblichen Schubkräfte, die beim Tennisspiel darauf übertragen werden, zerstört wird. Es tritt durch die lose obere Verarbeitung des Garnes ein schneller Verschleiß der Faser auf.In addition to the above disadvantageous properties of the rubber granulate, the fleece has the disadvantage that the original surface is destroyed after a short period of use by the considerable thrust forces that are transferred to it during tennis play. Due to the loose top processing of the yarn, the fiber wears out quickly.
Der Erfindung liegt die Aufgabe zugrunde, einen Tennisbodenbelag so auszubilden, daß durch den Gebrauch, die Struktur der Faser erhalten bleibt, der erforderliche Brems- und Gleiteffekt eintritt wenn der Boden bespielt wird und der Belag sich günstig pflegen läßt.The invention has for its object to provide a tennis flooring so that the use of the structure of the fiber is retained, the required braking and sliding effect occurs when the floor is used and the surface can be maintained cheap.
Das wird erreicht, durch ein Belagmaterial mit wenigstens einer strukturierten Oberseite aus Fasern, in die eine Menge eines Korngranulats eingestreut ist.This is achieved by a covering material with at least one structured top made of fibers, in which a lot of granular material is sprinkled.
Das Belagmaterial ist vorzugsweise ein strukturiertes Nadelvlies aüs synthetischen Fasern. Statt eines Nadelvlieses kann auch mit gutem Erfolg eine entsprechend strukturierte Tuftingware eingesetzt werden. Die Strukturierung soll möglichst in regelmäßigen Mustern Erhebungen und Vertiefungen ergeben, die die Oberfläche des Belagmaterials z.B. in Form von Rippen bedecken. Das Vlies erhält also eine Musterung. Es ergeben sich Faserzonen, die niedriger liegen und solche die höher liegen und dem Spieler einen festen Halt und damit einen guten Start zum Ball geben. Die Strukturierung erlaubt ein in sich festes Material z.B. Vlies, das insbesondere in den Vertiefungen,aber auch in höher liegenden Zonen Granulatkörner aufnimmt. Die Musterung kann waffelartig oder rippenartig sein, entscheidend sind die hoch- und tiefliegenden Bereiche.The covering material is preferably a structured needle fleece made of synthetic fibers. Instead of a needle fleece, an appropriately structured tufting product can also be used with great success. The structuring should result in elevations and depressions in regular patterns that cover the surface of the covering material, for example in the form of ribs. The fleece receives a pattern. The result is fiber zones that are lower and those that are higher, giving the player a firm grip and thus a good start to the ball. The structuring allows a solid material, for example fleece, which pellets in particular in the wells, but also in higher lying zones. The pattern can be waffle-like or rib-like; the high and low areas are decisive.
Bei dem Korkgranulat handelt es sich um eine Körnung bis etwa 3 mm φ, vorzugsweise um eine Körnung von 0,5 - 2,5 mm. Die Vertiefungen bilden quasi Depots für die Körnung und bewirken außerdem eine gleichbleibende Verteilung des Granulates auf der gesamten Oberfläche. Gleit- und Bremszonen sind ausgeglichen, d.h. es ergibt sich ein Tennisboden mit einer Oberfläche mit homogenen Eigenschaften. Das Granulat ist elastisch, um dem Belag eine entsprechende vertikale Elastizität zu geben. Es ist widerstandsfähig, um ein schnelles Zermahlen der Granulatteile zu verhindern. Das Granulat ist auch nicht härter als die Faser, so daß es die Faser mehr schont als verschleißt.The cork granulate is a grain size of up to approximately 3 mm φ, preferably a grain size of 0.5-2.5 mm. The recesses form quasi depots for the grain and also ensure a constant distribution of the granulate over the entire surface. Sliding and braking zones are balanced, i.e. the result is a tennis floor with a surface with homogeneous properties. The granulate is elastic in order to give the covering a corresponding vertical elasticity. It is resistant to prevent the granulate parts from being ground quickly. The granulate is also no harder than the fiber, so that it protects the fiber more than it wears out.
Anderes Belagmaterial als Nadelvliese ist auch deshalb oft vorteilhaft, weil Nadelvliese nach dem Aufrollen der Bahnen erhebliche Wicklungsspannungen enthalten können und sich des- halb nur schwer auf Klebebändern verlegen lassen. Es eignet sich auch nicht für selbstklebende Rückenbeschichtungen, die für Renovierungsprojekte erforderlich sind, wenn man auf bestehende Tennisbeläge neu verlegen will.Covering material other than needle-punched nonwovens is often also advantageous because needle-punched nonwovens can contain considerable winding tensions after the webs are rolled up and are therefore difficult to lay on adhesive tapes. It is also not suitable for self-adhesive back coatings that are necessary for renovation projects if you want to relocate to existing tennis surfaces.
Die Erfindung wird nun an einem Ausführungsbeispiel, welches in der einzigen Figur der Zeichnung als Schnitt dargestellt ist, näher beschrieben.The invention will now be described in more detail using an exemplary embodiment which is shown as a section in the single figure of the drawing.
In der Figur der Zeichnung bezeichnet das Bezugszeichen 1 das bahnförmige Belagsmaterial z.B. ein Nadelvlies oder eine entsprechende Tuftingware. Die Struktur des Belages ergibt sich durch rippenartige Erhebungen 2 und Vertiefungen 3. Das aufgebrachte Korkgranulat 4 sammelt sich in den Vertiefungen 3, die wie Depots wirken. Feinkörniges Granulat 5 befindet sich auch zwischen den Fasern der Erhebungen 2. Die Oberfläche des Belagmaterials ist natürlich nicht folienglatt sondern faserig rauh.In the figure of the drawing, reference numeral 1 denotes the sheet-like covering material e.g. a needle fleece or a corresponding tufted fabric. The structure of the covering results from rib-
Insgesamt gesehen, ergibt sich ein Belag mit dicht beieinander liegenden Gleit- und Bremsflächen, wobei die Bremsflächen, die Oberseiten der Erhebungen 2 sind, deren Bremswirkung durch Korngrößenbemessung und Dosierung beeinflußbar, d.h. in gewissen Grenzen steuerbar ist.Seen overall, there is a covering with sliding and braking surfaces lying close together, the braking surfaces being the upper sides of the
Die Vertiefungen 3 und die Erhebungen 2 liegen relativ dicht beieinander, so daß die aufzubringende Granulatmenge nicht zu groß wird. So sollte die Breite einer Vertiefung 3 und einer Erhöhung 2 5-6 mm möglichst nicht überschreiten und die Tiefe der Vertiefungen 3 höchstens 5 mm betragen.The depressions 3 and the
