Abstract

1. Rebound wall for tennis training using an inflatable air chamber, characterized in that the air chamber forming the rebound element consists of a one-piece, low-damping rectangular sheet (3) of a spaced fabric coated with rubber and filled with air at an over-pressure of 0.5-1.5 bar, the two external fabric lengths (5, 6) of which are held at constant separation by pile threads (7) extending perpendicular thereto and are joined air-tight to one another at the peripheral edge (8).

Description

Die Erfindung betrifft eine Prallwand für das Tennis-Training. Derartige Ubungswände, die im Freien stehen oder durch eine Hallenwand gebildet sind, bestehen üblicherweise aus unverkleidetem Beton, gegen die der Spieler die Bälle schlägt. Derartige Betonwände haben aber nur einen mäßigen Rückpralleffekt für die auftreffenden Bälle. Dadurch springt der Ball mit stark verminderter Geschwindigkeit auf den Spieler zurück, so daß dadurch die Situation erheblich von der beim reellen Spiel auf dem Spielfeld abweicht.Hier kommen nämlich die Bälle mit erheblich größerer Geschwindigkeit vom Gegenspieler zurück.The invention relates to a baffle for tennis training. Such exercise walls, which stand outdoors or are formed by a hall wall, usually consist of unclad concrete, against which the player hits the balls. However, such concrete walls only have a moderate rebound effect for the impacting balls. As a result, the ball bounces back at the player at a greatly reduced speed, which means that the situation differs considerably from that in real play on the field, because here the balls come back from the opponent at a considerably higher speed.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Prallwand zu schaffen, die eine erheblich größere Rückprallelastizität aufweist und damit den Verhältnissen bei einem echten Spiel auf dem Feld mit Gegner näher kommt.The invention is therefore based on the object of creating an impact wall which has a considerably greater resilience and thus comes closer to the conditions in a real game on the field with opponents.

Zur Lösung dieser Aufgabe ist erfindungsgemäß eine einteilige, rechteckige Platte aus einem mit Luft unter Überdruck gefüllten, gummibeschichteten Abstandsgewebe vorgesehen, dessen beide außenliegenden Gewebebahnen durch senkrecht verlaufende Polfäden auf konstanten Abstand gehalten und am umlaufenden Rand luftdicht miteinander verbunden sind.To achieve this object, a one-piece, rectangular plate is provided according to the invention from a rubber-coated spacer fabric filled with air under excess pressure, the two outer fabric webs of which are kept at a constant distance by perpendicular pile threads and are connected airtightly to one another at the peripheral edge.

Derartiges gummibeschichtetes Abstandsgewebe ist zwar grundsätzlich aus der DE-AS 21 48 401 nach seiner Herstellung und Verwendung für schwimmfähige Körper bekannt, ohne daß der wesentlichen Eigenschaft einer innewohnenden Rückprallelastizität besondere Beachtung geschenkt wurde.Such a rubber-coated spacer fabric is true basically known from DE-AS 21 48 401 after its manufacture and use for buoyant bodies, without special attention being paid to the essential property of an inherent rebound resilience.

Die erfindungsgemäße Abstandsgewebe-Platte kann über ein Ventil mittels einer Luftpumpe mit Luft von einem Betriebsdruck von etwa 0,5 - 1,5 bar gefüllt werden. Durch die jetzt vorhandenen Gasfederung ergibt sich ein erheblich höherer Rückpralleffekt beim Auftreffen des Balles. Dabei kann der Innendruck beliebig variiert werden, so daß sich eine stufenlos einstellbare Federcharakteristik ergibt.The spacer fabric plate according to the invention can be filled with air at an operating pressure of approximately 0.5-1.5 bar via a valve by means of an air pump. The gas suspension now available results in a significantly higher rebound effect when hitting the ball. The internal pressure can be varied as desired, so that there is a continuously adjustable spring characteristic.

Weitere zweckmäßige Ausgestaltungen sind in den Unteransprüchen genannt.Further expedient configurations are mentioned in the subclaims.

Anhand einer schematischen Zeichnung sind Aufbau und Wirkungsweise eines Ausführungsbeispiels nach der Erfindung näher erläutert. Dabei zeigen

  • Fig. 1 eine perspektivische Ansicht einer Gesamtanordnung einer Tennis-Ubungswand und
  • Fig. 2 einen Querschnitt durch eine Prallwand mit einer möglichen Aufhängung und Befestigung.
The structure and mode of operation of an exemplary embodiment according to the invention are explained in more detail with reference to a schematic drawing. Show
  • Fig. 1 is a perspective view of an overall arrangement of a tennis exercise wall and
  • Fig. 2 shows a cross section through a baffle with a possible suspension and attachment.

Wie man aus Fig. 1 ersieht, ist vor einer starren Wand 1, wie sie üblicherweise als Ubungswand verwendet wird und die meist aus Beton ist, oberhalb des Tennisnetzes 2 die erfindungsgemäße Platte 3 aus gummibeschichtetem Abstandsgewebe aufgehängt.As can be seen from Fig. 1, in front of a rigid wall 1, as is usually used as a practice wall and which is usually made of concrete, the plate 3 according to the invention made of rubber-coated spacer fabric is suspended above the tennis net 2.

Wie dazu in Fig. 2 im einzelnen dargestellt ist, besteht nach dem Teilquerschnitt durch die Platte 3 das Abstandsgewebe aus den beiden Gewebebahnen 5 und 6, die über senkrecht dazu verlaufende sog. Polfäden 7 miteinander verbunden und auf konstanten Abstand gehalten sind. Die Gewebebahnen 5 und 6 sind auf ihrer Außenseite mit einer luftdichten Gummibeschichtung versehen und am umlaufenden Rand 8 abdichtend verklebt bzw. zusammenvulkanisiert. In einer Ecke der Platte 3 befindet sich ein Füllventil 9, über das die Platte 3 mittels einer Luftpumpe mit Luft gefüllt werden kann. Der dabei zweckmäßigerweise zu wählende Druck betragt zweckmäßigerweise 0,5 bis 1,5 bar, wobei durch unterschiedlichen Innendruck stufenlos die gewünschte Federcharakteristik der Platte 3 eingestellt werden kann.As shown in detail in FIG. 2, there is the distance after the partial cross section through the plate 3 Fabric from the two fabric webs 5 and 6, which are connected to each other via so-called pile threads 7 and are kept at a constant distance. The fabric webs 5 and 6 are provided on their outside with an airtight rubber coating and glued or vulcanized together at the peripheral edge 8. In a corner of the plate 3 there is a filling valve 9, via which the plate 3 can be filled with air by means of an air pump. The pressure which is expediently to be selected is expediently 0.5 to 1.5 bar, the desired spring characteristic of the plate 3 being able to be set continuously by means of different internal pressures.

Die Abstandsgewebe-Platte 3 ist jetzt zweckmäßigerweise zunächst auf eine starre Rückwand 10, beispielsweise eine Sperrholz- oder Spanplatte, vollflächig aufgeklebt. Diese Rückwand 10 ist dann über an ihrer oberen Kante befestigte Bügel 11 über die stationäre Wand 1 gehängt und kann somit jederzeit leicht wieder abgenommen werden.Zweckmäßigerweise ist darüberhinaus noch der freie Spalt zwischen der Oberkante der Platte 3 und der Oberkante der starren Wand 1 mit einer Abdeckung 12 versehen, um zu verhindern, daß Bälle in diesen Zwischenraum fallen.The spacer fabric plate 3 is now expediently glued over the entire surface to a rigid rear wall 10, for example a plywood or chipboard. This rear wall 10 is then hung via brackets 11 attached to its upper edge over the stationary wall 1 and can therefore be easily removed at any time Cover 12 to prevent balls from falling into this space.

Gegen die so montierte Platte 3, die in etwa eine Größe von 1,5 mal 5 m aufweist und die mit einem entsprechenden Luftdruck beaufschlagt ist, können dann in herkömmlicher Weise Übungsbälle 15 geschlagen werden. Die luftgefüllte Abstandsgewebe-Platte 3 weist dabei eine erheblich höhere Rückprallelastizität als eine herkömmliche Ubungswand aus starrem Material auf und kommt in ihren Eigenschaften den Verhältnissen auf dem Spielfeld mit einem echten Gegner sehr nahe. Damit werden die gewünschten Trainingsmöglichkeiten erheblich verbessert. Da die Platte 3 darüberhinaus sehr wetterfest ist, kann sie auch bei Regen im Freien belassen werden und braucht praktisch nur nach Ende der Freiluftsaison abgenommen zu werden.Practice balls 15 can then be hit in a conventional manner against the plate 3 thus assembled, which has a size of approximately 1.5 by 5 m and which is subjected to a corresponding air pressure. The air-filled spacer fabric plate 3 has a considerably higher resilience than a conventional exercise wall made of rigid material and its properties come very close to the conditions on the field with a real opponent. This significantly improves the desired training options. Since the plate 3 above is very weatherproof, it can also be left outdoors when it rains and practically only needs to be removed after the end of the outdoor season.
