Surfacing for tennis courts consisting of a web material which has projections on its upper side, characterized in that the web material is a prefabricated sheet-like material of resilient plastic, in that the projections are produced with the web material (8 ; 108 ; 208; 308 ; 308a), form at least approximately a regularly repeating pattern and are in each case inclined towards the net (2), and in that the longitudinal direction of the web extends in the longitudinal direction of the tennis court (1).

Description

Die Erfindung bezieht sich auf einen Bodenbelag für Tennisplätze aus Bahnmaterial, das an seiner Oberseite Vorsprünge trägt.The invention relates to a floor covering for tennis courts made of web material, which has projections on its top.

Bei einem bekannten Bodenbelag dieser Art (DE-A-25 20 550) werden auf einem Korngerüst eine erste Bahn aus Stoffen wie Polyäthylen und auf diese eine zweite Bahn aus Stoffen wie Polyvinylchlorid aufgelegt. Auf diese obere Bahn werden Berauhungselemente aus termoplastischen oder kalt aushärtenden Kunststoffen mittels eines Schweiß- oder Klebeprozesses aufgedrückt. Die Herstellung solcher Bodenbeläge ist sehr mühsam, da die die Vorsprünge bildenden Körperchen erst an Ort und Stelle aufgebracht werden können. Außerdem ist es schwierig, eine gleichmäßige Beschichtung des Bodens mit diesen Körnern zu erreichen. Die Oberflächeneigenschaften dieses Bodenbelages hängen daher in erheblichem Maße vom handwerklichen Können der Arbeiter ab, welche den Belag herstellen.In a known floor covering of this type (DE-A-25 20 550), a first web of materials such as polyethylene and a second web of materials such as polyvinyl chloride are placed on a grain structure. Roughing elements made of thermoplastic or cold-curing plastics are pressed onto this upper web by means of a welding or gluing process. The production of such floor coverings is very tedious, since the bodies forming the projections can only be applied on the spot. It is also difficult to achieve an even coating of the soil with these grains. The surface properties of this floor covering therefore depend to a considerable extent on the manual skills of the workers who manufacture the covering.

Es ist ferner ein Bodenbelag bekannt, bei dem eine Kunststoff-Basisschicht aus durch Polyurethan gebundenem Kautschukgranulat besteht, wobei das Granulat an der Oberseite Vorsprünge bildet. Auf diese Basisschicht werden als Verschleiß- und Gleitschicht lose Kautschukgranulatkörnchen aufgestreut, die von den Vorsprüngen gehalten werden, so daß sich, wie auf einem Sandplatz, die Möglichkeit ergibt, bremsend zu rutschen. Muskeln, Sehnen und Knochengerüst des Tennisspielers werden weniger beansprucht als auf einem Hartplatz oder auf einem Teppichboden. Hierfür gelten ähnliche Nachteile wie für den zuvor beschriebenen Bodenbelag.A floor covering is also known in which a plastic base layer consists of rubber granules bonded by polyurethane, the granules forming projections on the upper side. Loose rubber granules, which are held by the projections, are sprinkled onto this base layer as a wear and sliding layer, so that, like on a clay court, there is the possibility of slipping on the brakes. The tennis player's muscles, tendons and bones are less stressed than on a hard court or on a carpeted floor. Similar disadvantages apply to this as for the previously described floor covering.

Der Erfindung liegt die Aufgabe zugrunde, einen Bodenbelag der eingangs beschriebenen Art anzugeben, der über die gesamte Fläche gleichmäßig ausgebildet ist, auch von ungeübtem Personal verlegt werden kann und dem Tennisspieler beim Starten eine bessere Abstützung und beim Bremsen ein besseres Rutschen ermöglicht.The invention has for its object to provide a floor covering of the type described above, which is evenly formed over the entire surface, can also be installed by inexperienced personnel and allows the tennis player better support when starting and better braking when braking.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Bahnmaterial ein vorgefertigtes Flächenmaterial aus elastischem Kunststoff ist, daß die Vorsprünge mit dem Bahnmaterial gefertigt sind, zumindest annähernd ein regelmäßig wiederkehrendes Muster bilden und jeweils zum Netz hin geneigt sind, und daß die Bahnlängsrichtung in Längsrichtung des Tennisplatzes verläuft.This object is achieved in that the web material is a prefabricated sheet material made of elastic plastic, that the projections are made with the web material, at least approximately form a regularly recurring pattern and are inclined towards the net, and that the longitudinal direction of the web in the longitudinal direction of the tennis court runs.

Infolge der Vorfertigung bereitet es keine Schwierigkeiten, die Vorsprünge so auszugestalten, daß sie an allen Stellen des fertigen Platzes die gleichen Gleiteigenschaften ergeben. Die Vorsprünge werden bei der Herstellung des Bahnmaterials beispielsweise mit Hilfe von Prägewalzen geformt. Da die Vorsprünge einstückig mit dem Bahnmaterial ausgebildet sind, sind sie sehr fest mit dem Bahnmaterial verbunden. Dies ergibt eine hohe Belastbarkeit und Lebensdauer. Auch die Elastizitätseigenschaften des Bodenbelags sind über den gesamten Tennisplatz gleich. Hinzu kommt, daß das Bahnmaterial ohne Schwierigkeiten von ungelernten Handwerkern verlegt werden kann. Das Bahnmaterial läßt sich in Rollen anliefern und großflächig verlegen, so daß die Verlegungszeit kurz ist. Insgesamt läßt sich ein solcher Bodenbelag preisgünstiger als bisher verlegen. Die einseitig gleichsinnige Neigung der Vorsprünge führt zu unterschiedlichen Eigenschaften in Abhängigkeit von der Belastungsrichtung. Da die Vorsprünge zum Netz hin geneigt sind, ergibt sich eine sichere Abstützung beim Starten zum Netz hin, gleichzeitig aber das gewünschte Rutschen in Richtung auf das Netz.As a result of the prefabrication, there is no difficulty in designing the projections in such a way that they give the same sliding properties at all points in the finished place. The protrusions are shaped, for example, with the aid of embossing rollers in the production of the web material. Since the projections are formed in one piece with the web material, they are very firmly connected to the web material. This results in high resilience and durability. The elasticity properties of the flooring are also the same across the entire tennis court. In addition, the sheet material can be laid by unskilled craftsmen without difficulty. The web material can be delivered in rolls and laid over a large area, so that the laying time is short. Overall, such a floor covering can be installed more cheaply than before. The inclination of the projections in the same direction leads to different properties depending on the direction of loading. Since the projections are inclined towards the net, there is secure support when starting towards the net, but at the same time the desired sliding in the direction of the net.

Insbesondere können die Bahnen eine Breite von 200 bis 210 cm haben. Ein normaler Tennisplatz läßt sich auf diese Weise mit einer kleinen Zahl von noch handhabbaren Rollen auslegen. Da die Bahnlängsrichtung in Längsrichtung des Tennisplatzes verläuft, reicht eine Bahnenlänge von etwa 19 m über den halben Platz.In particular, the webs can have a width of 200 to 210 cm. A normal tennis court can be laid out in this way with a small number of still manageable roles. Since the length of the lane runs in the longitudinal direction of the tennis court, a lane length of about 19 m extends over half the court.

Günstig ist es ferner, wenn benachbarte Bahnen längs ihren aneinandergrenzenden Rändern miteinander verschweißt sind. Dies kann insbesondere durch Kaltverschweißung mit einem dem Bahnmaterial angepaßten ZweiKomponenten-Kunststoff erfolgen.It is also favorable if adjacent webs are welded to one another along their adjoining edges. This can be done in particular by cold welding with a two-component plastic adapted to the web material.

Mit besonderem Vorteil ist das Bahnmaterial lose auf einem festen Untergrund verlegt. Gewicht und Material der Basisschicht machen es in der Praxis unnötig, eine zusätzliche Verklebung vorzunehmen.The web material is particularly loosely laid on a solid surface. In practice, the weight and material of the base layer make it unnecessary to carry out additional gluing.

Dies gilt auch deshalb, weil wegen der Gleitschicht keine übermäßig großen Kräfte in Richtung des Bodenbelages auftreten.This also applies because no excessive forces occur in the direction of the floor covering due to the sliding layer.

Allerdings empfiehlt es sich in manchen Fällen, daß das Flächenmaterial durch in den Untergrund geschossene Nägel oder Klammern oder durch Schrauben, die in in den Untergrund eingesetzte Dübel greifen, in seiner Lage gesichert ist. Auf diese Weise wird das Bahnmaterial immer glatt oder sogar gespannt gehalten.However, it is recommended in some cases that the surface material is secured in its position by nails or staples shot into the ground or by screws that reach into dowels inserted into the ground. In this way, the web material is always kept smooth or even tensioned.

Mit besonderem Vorteil weist das Bahnmaterial eine textile Verstärkungseinlage auf. Da die Elastizität zum Teil durch die Profilierungen an der Unterseite beeinflußt werden kann, erlaubt es die Verstärkungseinlage, die Basisschicht noch dünner und daher materialsparender auszuführen.The web material has a textile reinforcement insert with particular advantage. Since the elasticity can be influenced in part by the profiles on the underside, the reinforcement insert allows the base layer to be made even thinner and therefore less material.

Insbesondere ist die textile Verstärkungseinlage ein Gewebe aus Polyäthylen-Spinnfaserzwirn. Es genügt ein verhältnismäßig grobmaschiges Netz.In particular, the textile reinforcement insert is a woven fabric made of polyethylene spun yarn. A relatively coarse-meshed network is sufficient.

Hierbei sollte sich die textile Verstärkungseinlage in der unteren Hälfte des Bahnmaterials befinden, damit die elastische Verformung der oberen Vorsprünge nicht beeinträchtigt wird.The textile reinforcement insert should be located in the lower half of the web material so that the elastic deformation of the upper projections is not impaired.

Das Bahnmaterial kann im wesentlichen aus einem Polyester bestehen, insbesondere wenn eine Verstärkungseinlage benutzt wird. Man kann es aber auch im wesentlichen aus geschäumtem Polyvinylchlorid bestehen lassen. Es kommen noch weitere Kunststoffe in Betracht, z. B. Polyurethan.The web material can consist essentially of a polyester, in particular if a reinforcing insert is used. One can but also let it consist essentially of foamed polyvinyl chloride. There are other plastics, z. B. polyurethane.

Mit besonderem Vorteil hat das Bahnmaterial eine Härte von 60 bis 65 Shore. Die Vorfertigung des Bahnmaterials macht es möglich, eine solche Härte gleichzeitig mit der gewünschten Elastizität vorzusehen. Die größere Härte wiederum erlaubt es, den Vorsprüngen eine höhere Lebensdauer zu geben.The web material has a particular hardness of 60 to 65 Shore. The prefabrication of the web material makes it possible to provide such hardness at the same time as the desired elasticity. The greater hardness in turn allows the projections to have a longer service life.

Das Bahnmaterial hat vorzugsweise eine Gesamtdicke von weniger als 12 mm, vorzugsweise 8 bis 10 mm. Entsprechend gering ist der Materialaufwand. Trotzdem läßt sich infolge der Vorfertigung eine ausreichende Festigkeit und Elastizität vorsehen.The web material preferably has an overall thickness of less than 12 mm, preferably 8 to 10 mm. The cost of materials is correspondingly low. Nevertheless, sufficient strength and elasticity can be provided as a result of the prefabrication.

Die Vorsprünge an der Oberseite haben zweckmäßigerweise eine Höhe von 2 bis 3 mm.The projections on the top advantageously have a height of 2 to 3 mm.

Mit besonderem Vorteil stehen die Vorsprünge ringsum frei. Insbesondere können sie Abstände von 3 bis 4 mm voneinander haben, damit Teilchen einer Gleitschicht in ausreichendem Maß zwischen die Vorsprünge greifen können.The projections are particularly free all around. In particular, they can have distances of 3 to 4 mm from one another so that particles of a sliding layer can reach between the projections to a sufficient extent.

Bei einer bevorzugten Ausführungsform sind 7 bis 10 Vorsprünge pro cm2 vorgesehen.In a preferred embodiment, 7 to 10 projections per cm 2 are provided.

Vorzugsweise verjüngen sich die Vorsprünge nach oben, wodurch sich die Gleiteigenschaften verbessern.The projections preferably taper upwards, which improves the sliding properties.

In manchen Fällen ist es empfehlenswert, wenn Vorsprünge unterschiedlicher Größe nebeneinander angeordnet sind. Auf diese Weise läßt sich jede gewünschte Oberflächeneigenschaft des Bodenbelages erzielen.In some cases it is recommended that protrusions of different sizes are arranged side by side. In this way, any desired surface property of the floor covering can be achieved.

Die Profilierungen an der Unterseite sollten zweckmäßigerweise eine Höhe von etwa 1,5 mm haben. Dies führt zu einer ausreichend hohen Elastizität.The profiles on the underside should expediently have a height of approximately 1.5 mm. This leads to a sufficiently high elasticity.

Insbesondere können die Profilierungen zur Bildung von Luftkissen nach dem Verlegen Vertiefungen mit ringsum geschlossenen Rändern aufweisen. Diese Luftkissen führen zu einer besonders hohen Maß an Elastizität.In particular, the profiles for forming air cushions can have depressions with all-round closed edges after laying. These air cushions lead to a particularly high degree of elasticity.

Des weiteren kann dafür gesorgt sein, daß das Bahnmaterial perforiert ist und die Perforierungen in zwischen den Profilierungen verbleibenden untereinander verbindenen Vertiefungen münden. Das Bahnmaterial läßt sich dann auch auf Außenplätzen oder in Hallen mit Schiebedach anwenden. Wasser fließt durch die Perforierungen rasch in eine entsprechende Drainage ab.Furthermore, it can be ensured that the web material is perforated and the perforations open into interconnecting depressions remaining between the profiles. The sheet material can then also be used on outdoor spaces or in halls with a sliding roof. Water quickly flows through the perforations into an appropriate drainage.

Die Gleitschicht braucht nicht aus Kautschukgranulat bestehen. Statt dessen kann auch das auf Freiplätzen übliche Ziegelmehl oder geflammter Quarzsand benutzt werden. Besonders empfehlenswert ist eine Gleitschicht aus einem silikonhaltigen, flüssig aufgetragenem Material, das beispielsweise aufgesprüht wird. Hiermit enfällt das häufige Glätten (Abziehen) einer aufgestreuten Gleitschicht.The sliding layer need not consist of rubber granulate. Instead, the usual brick flour or flamed quartz sand can be used. A sliding layer made of a silicone-containing, liquid-applied material that is sprayed on, for example, is particularly recommended. This eliminates the frequent smoothing (peeling) of a sprinkled sliding layer.

Die Erfindung wird nachstehend anhand in der Zeichnung dargestellter, bevorzugter Ausführungsbeispiele näher erläutert. Es zeigen:

The invention is explained in more detail below with reference to preferred exemplary embodiments illustrated in the drawing. Show it:
  • 1 schematically shows the top view of a tennis court,
  • 2 shows a longitudinal section through the floor of the square at the height of the network,

In Fig. 1 ist ein Tennisplatz 1 mit seinem Netz 2 veranschaulicht. Der Bodenbelag dieses Platzes besteht aus acht Bahnen 3, 4, 5 und 6 sowie 3a, 4a, 5a und 6a, die je eine Breite b = 2,10 m und eine Länge 1 = 19 m aufweisen. Die Bahnen werden jeweils in Rollen angeliefert und auf einem vorbereiten festen Boden 7 verlegt. Ein Verkleben dieser Bahnen auf dem Boden 7 ist in der Regel nicht erforderlich.1 shows a tennis court 1 with its net 2. The floor covering of this course consists of eight tracks 3, 4, 5 and 6 as well as 3a, 4a, 5a and 6a, each with a width b = 2.10 m and a length 1 = 19 m. The sheets are delivered in rolls and laid on a prepared solid floor 7. It is generally not necessary to glue these sheets to the floor 7.

Fig. 2 zeigt einen Längsschnitt durch die Bahnen 3 und 4. Diese haben eine Gesamthöhe h = 10 mm, weisen an der Oberseite 2 bis 3 mm hohe ringsum freie Vorsprünge 8 auf und besitzen an der Unterseite 1,5 mm tiefe Profilierungen 9, durch welche sich ringsum Beschlossene Vertiefungen 10 ergeben. Diese Vertiefungen stellen im verlegten Zustand Luftkissen dar, welche die Elastizität erhöhen. Nahe den Vertiefungen verläuft in den Bahnen ein textiles Gewebe oder Netz, das als Verstärkungseinlage 11 dient. Das Bahnmaterial besteht aus Polyester oder geschäumtem Polyvinylchlorid. Die Vorsprünge B und Profilierungen 9 sind während der Herstellung der Kunststoffbahnen durch Prägewalzen erzeugt worden. Sie können auch nachträglich durch Prägewalzen angebracht worden sein. Das Bahnenmaterial weist auch eine gewisse Eigenelastizität auf.Fig. 2 shows a longitudinal section through the webs 3 and 4. These have a total height h = 10 mm, have 2 to 3 mm high free projections 8 on the top and have 1.5 mm deep profiles 9, on the underside which result in closed recesses 10. When installed, these depressions represent air cushions that increase the elasticity. A textile fabric or net, which serves as a reinforcing insert 11, runs in the webs near the depressions. The sheet material is made of polyester or foamed polyvinyl chloride. The projections B and profilings 9 were produced by embossing rolls during the production of the plastic sheets. They can also be retrofitted using embossing rollers. The sheet material also has a certain inherent elasticity.

Zwischen den Rändern benachbarter Bahnen ist eine Naht 13 vorgesehen, die die beiden Bahnen zusammenhält. Diese kann nach dem Verlegen mittels eines pistolenartigen Werkzeugs, das zwei Kunststoff-Komponenten in den Spalt zwischen den Rändern einführt, erzeugt werden. Zur Lagesicherung sind Nägel 14 mittels eines Nagelschußapparates durch den Bodenbelag 1 in den Untergrund eingebracht. Dies geschieht vorzugsweise an den Rändern des Spielfelds. Als Gleitschicht 17 dient ein silikonhaltiges Material, das im flüssigen Zustand aufgetragen, insbesondere aufgesprüht worden ist und nun der Oberfläche der Vorsprünge 8 eine bessere Gleitfähigkeit verleiht.A seam 13 is provided between the edges of adjacent webs, which holds the two webs together. After laying, this can be created using a pistol-like tool that introduces two plastic components into the gap between the edges. To secure the position, nails 14 are inserted into the ground through the floor covering 1 by means of a nail gun. This is preferably done at the edges of the field. A silicone-containing material is used as the sliding layer 17, which has been applied in the liquid state, in particular sprayed on, and now gives the surface of the projections 8 better sliding properties.

Fig. 3 zeigt, daß die ringsum freien Vorsprünge 8 die gleiche Größe haben und regelmäßig über die Oberfläche der Bahn verteilt sind. Der gegenzeitige Abstand liegt zwischen 3 und 4 mm, so daß pro cm2 acht Vorsprünge mit einem Durchmesser von etwa 1,5 mm vorhanden sind.Fig. 3 shows that the all around free projections 8 have the same size and are regularly distributed over the surface of the web. The current distance is between 3 and 4 mm, so that there are eight projections with a diameter of about 1.5 mm per cm 2 .

Die in Fig. 4 veranschaulichte Unterseite der Bahnen der Fig. 2 läßt erkennen, daß die Vertiefungen 10 zwischen den Profilierungen 9 ringsum Beschlossen sind. Die Vertiefungen sind quadratisch, können aber auch beliebige andere Umrisse haben.The underside of the tracks of FIG. 2 illustrated in FIG. 4 shows that the depressions 10 between the profiles 9 are closed all around. The depressions are square, but can also have any other outlines.

Bei der in Fig. 5 veranschaulichten Variante einer Materialbahn 103 sind die ringsum freien Vorsprünge 108 gleichsinnig schräggestellt. Ihre Mittelachsen weisen daher auf das Netz 2. Die entsprechenden Vorsprünge bei einer auf der anderen Seite des Netzes liegenden Bahn sind entgegengesetzt geneigt. Die einzelnen Vorsprünge 108 verjüngen sich nach oben, so daß sie fest mit der übrigen Materialbahn verbunden sind. Der Raum 115 zwischen den Vorsprungen 108 ist mit Teilchen 116 gefüllt, welche eine Gleitschicht 117 bilden. Diese Teilchen können ebenfalls aus dem Granulat eines elastischen Kunststoffs bestehen.In the variant of a material web 103 illustrated in FIG. 5, the projections 108 which are free all around are inclined in the same direction. Their central axes therefore point to the network 2. The corresponding projections on a path lying on the other side of the network are inclined in opposite directions. The individual projections 108 taper upwards so that they are firmly connected to the rest of the material web. The space 115 between the projections 108 is filled with particles 116, which form a sliding layer 117. These particles can also consist of the granulate of an elastic plastic.

Wenn der Tennisspieler sich zum Start auf der Gleitschicht 117 abstützt, findet sein Schuh einen festen Halt an den Vorsprüngen 108. Wenn dagegen mit dem Schuh in Richtung auf das Netz 2 gebremst wird, rutschen Teilchen 116 über die Vorsprünge 108 hinweg, so daß sich ein sanftes Abbremsen ergibt.When the tennis player is supported on the sliding layer 117 at the start, his shoe finds a firm hold on the protrusions 108. On the other hand, when the shoe is braked in the direction of the net 2, particles 116 slip over the protrusions 108 so that they stick gentle braking results.

Außerdem ist die Bahn 103 mit Perforierungen 118 versehen, durch die Wasser nach unten ablaufen und durch eine Drainage abgeführt werden kann.In addition, the web 103 is provided with perforations 118 through which water can flow downwards and be drained off through a drainage.

Bei der Ausführungsform nach Fig. 6 ist die Oberseite einer Bahn 203 mit rippenförmigen Vorsprüngen 208 versehen. Die rippenförmigen Vorsprünge kreuzen sich, so daß geschlossene Zwischenräume 215 verbleiben, welche die Teilchen der Gleitschicht aufnehmen.In the embodiment according to FIG. 6, the top of a web 203 is provided with rib-shaped projections 208. The rib-shaped projections intersect so that closed gaps 215 remain which receive the particles of the sliding layer.

Fig. 7 zeigt die Draufsicht auf eine weitere Materialbahn 303. Bei ihr wechseln kleinere Vorsprünge 308 mit größeren Vorsprüngen 308a ab.FIG. 7 shows the top view of a further material web 303. With it, smaller projections 308 alternate with larger projections 308a.

Fig. 8 zeigt die Unterseite einer Materialbahn 103, bei der die Profilierungen 109 einzelne Vorsprünge bilden, also die Vertiefungen 110 untereinander verbunden sind. Die Perforierungen 118 münden in diese Vertiefungen 110, so daß das Wasser zu einem Abfluß hin ablaufen kann.8 shows the underside of a material web 103 in which the profiles 109 form individual projections, that is to say the depressions 110 are connected to one another. The perforations 118 open into these depressions 110 so that the water can run off to a drain.

Die Farbe der Bahnen ist vorzugsweise grün oder ziegelrot. Zur Einfärbung der weißen Feldlinien sollte eine molekulare Farbstoffbindung möglich sein.The color of the sheets is preferably green or brick red. Molecular dye binding should be possible to color the white field lines.

Der Bodenbelag eignet sich nicht nur für Tennisplätze sondern auch für Squash-Plätze und ähnliche Sportstätten.The flooring is not only suitable for tennis courts but also for squash courts and similar sports facilities.
