Abstract

Tennis ball serving systems are designed as ball serving systems in which two counter-rotating discs are adjusted so that the tennis ball, on covering the set distance, is given the necessary serving speed. Any desired direction of service can be obtained by pivoting or sliding the serving discs. The ball serving system invented by me and presented in the claims permits the simulation of all ball serving situations which are possible in tennis. This is because, by pivoting the serving discs from vertical to horizontal 0-90 DEG to right and left in accordance with the drawing in Figure 2, and the differing speed of rotation of the discs, the tennis ball is given axes of rotation which correspond to all ball trajectory possibilities. My ball serving system now makes it possible to serve all three types of service for right- and left-handers in a correct simulation of play. <IMAGE>

Iennisballwurfsystem mit Balldrehung Stand der Technik Tennisballwurfmaschinen bzw. Systeme sind bekannt als horizontale und vertikale WurSsysteme. Figur 1 + Figur 3 Beide Systeme haben gemeinsam, daß die Wurfrichtung durch Richtungsänderung, also Verschiebung der Ballwurfscheiben erfolgt.Tennis ball throwing system with ball spinning State of the art tennis ball throwing machines or systems are known as horizontal and vertical WurSsysteme. Figure 1 + figure 3 Both systems have in common that the throwing direction is changed by changing direction, i.e. The ball throwing discs are shifted.

Erfindungsbeschreibung Das von mir erfundene Tennisballwurfsystem ist von der horizontalen Wurfrichtung in die vertikale nach rechts und links schwenkbar. Figur 2 Es beruht darauf, daß die Ballwurfscheiben von der horizontalen in die vertikale Wurfrichtung, sowie nach rechts als auch nach links geschwenkt werden kann. Diese Schwenkung in die verschiedenen Winkelstellungen der Ballwurfscheiben von vertikal nach horizontal bewirkt, daß der Wurfball eine Achsendrehung erfährt und dadurch alle Ballwurfmöglichkeiten erzeugt werden können.Description of the invention The tennis ball throwing system I invented can be swiveled to the right and left from the horizontal throwing direction to the vertical. Figure 2 It is based on the fact that the ball throwing discs from the horizontal to the vertical Throw direction, as well as to the right and to the left can be swiveled. These Pivoting into the various angular positions of the ball throwing discs from vertical horizontally causes the throwing ball to experience an axis rotation and thereby all ball throwing possibilities can be generated.

Der Schwenkbereich von vertikal nach links wie auch von vertikal nach rechts erlaubt damit die gleiche Ballwurfsituation, sowohl für Linkshänder als auch für Rechtshänder.The swivel range from vertical to left as well as from vertical to right thus allows the same ball throwing situation, both for left-handers and for right-handers.

Diese Schwenkung von vertikal nach horizontal bzw. umgekehrt ergibt einen Wurfball, der beim Aufschlag seitlich abspringt.This pivoting from vertical to horizontal or vice versa results a throwing ball that bounces off to the side when it is served.

In das schwenkbare Ballwurfsystem ist die Verschiebung der Ballwurfscheiben, sowie eine differenzierte Drehzahl der Wurfscheiben integriert, um alle erdenklichen Drallmöglichkeiten zu erreichen.In the swiveling ball throwing system, the displacement of the ball throwing discs is as well as a differentiated speed of the clay targets integrated to all imaginable To achieve twist possibilities.

Durch eine Fernsteuerung in das Wurfsystem, ist dem Tennisspieler die Möglichkeit gegeben, von seinem Standort aus die Wurfbälle vorzuprogrammieren.Through a remote control in the throwing system, the tennis player is given the opportunity to pre-program the throwing balls from his location.

Ein integrierter Zufallsgenerator in meinem Ballwurfsy-stem bedeutet, daß der Tennisspieler, der einer Ballwurfmaschine gegenübersteht, mit allen Spielsituationen, ähnlich einem menschlichen Tennisspieler konfrontiert wird.An integrated random generator in my ball throwing system means that the tennis player facing a ball throwing machine with all game situations, similar to a human tennis player.
