EinleitungIntroduction

Bälle sind ein beliebtes Spielzeug für Kinder und Erwachsene, da sie zur Bewegung animieren und die Geschicklichkeit trainieren.Balls are a popular toy for children and adults because they encourage movement and train dexterity.

Stand der Technik und KritikState of the art and criticism

Die bekannten Bälle .sind voll oder hohl und, haben einenThe well-known balls are solid or hollow and have a

.zentrischen Schwerpunkt. Dadurch haben sie eine relativ gut.centric center of gravity. This gives them a relatively good

vorausberechenbare Flugbahn und . ein ebenfalls recht gut vorausberechenbares Abprallverhalten.predictable flight path and a rebound behavior that is also quite predictable.

Da die Bewegung eines Balles mit zentrischem Schwerpunkt mit einiger Übung leicht vorausberechnet werden kann, fehlt beim Spiel das Überraschungsmoment.Since the movement of a ball with a central center of gravity can easily be predicted with some practice, the element of surprise is missing from the game.

Aufgabe der ErfindungObject of the invention

Aufgabe der Erfindung war es, einen Ball zu schaffen, dessen Flugbahn und Abprallwinkel nur schwer vorausberechnet werden können.The aim of the invention was to create a ball whose trajectory and rebound angle are difficult to predict.

Erfindungsgemäße LösungInventive solution

Diese Aufgabe wird erfindungsgemäß gelöst durch einen Ball (l), welcher in seinem Inneren einen exzentrischen, schweren Körper (2J hat, so daß der Schwerpunkt des Balles exzentrisch ist.This object is achieved according to the invention by a ball (l) which has an eccentric, heavy body (2J) inside it, so that the center of gravity of the ball is eccentric.

Vorteile der ErfindungAdvantages of the invention

Dieser Ball mit.exzentrischem Schwerpunkt hat eine Flugbahn und ein Apprallverhalten/ welches nur schwer vorausberechnet werden kann und deshalb interessante Überraschungen bietet.This ball with an eccentric center of gravity has a trajectory and an impact behavior that is difficult to predict and therefore offers interesting surprises.

BeschreibungDescription

Im folgenden wird ein bevorzugtes Ausführungsbeispiel des Ball/ mit exzentrischem Schwerpunkt anhand der Zeichnung Fig. 1 beschrieben.In the following, a preferred embodiment of the ball/ with eccentric center of gravity is described using the drawing Fig. 1.

Der Ball (1) hat einem schweren, exzentrischen Kern- (2). Deshalb liegt auch der Schwerpunkt des Balles exzentrisch. Dadurch macht der Ball beim Wurf eine Taumelbewegung und hat beim Aufprall auf eine feste Fläche je nach Auftreffwinkel und Drall einen nur schwer vorhersagbaren Abprallwinkel.The ball (1) has a heavy, eccentric core (2). Therefore, the ball's center of gravity is also eccentric. This causes the ball to wobble when thrown and, when it hits a solid surface, has a rebound angle that is difficult to predict depending on the angle of impact and spin.

Claims (3)

■Bat ant anspräche■Bat ant addresses 1.) Ball dadurch gekennzeichnet, daß der Schwerpunkt, exzentrisch ist.1.) Ball characterized by the fact that the center of gravity is eccentric. 2.) Ball nach Anspruch 1 dadurch gekennzeichnet, daß sich im Inneren des Balles außerhalb des Zentrums ein Körper befindet, welcher eine andere Dichte hat, als der restliche Ball.2.)
