Title (EN) DYNAMICALLY BALANCED OVOID SPORTS BALL
(FR) BALLON DE SPORT OVOÏDE ÉQUILIBRÉ DYNAMIQUEMENT
Abstract:
(EN) A dynamically balanced inflatable ovoid sports ball (10) has a polar axis x, a first principal equatorial axis y and a second principal equatorial axis z. The axes x, y, z are mutually perpendicular and coincide at an origin o at the ball's centre of geometry. The ball (10) comprises an air inlet valve (11) to permit inflation thereof, and at least one additional mass element (12) adapted to counter-balance the mass of the valve (11). The air inlet valve (11) and each additional mass element (12) are arranged relative to one another such that the centre of mass of the ball (10) is substantially coincident with the origin o, and such that the difference between the average mass moment of inertia Iyy of the ball (10) when rotated about the first principal equatorial axis y, and the average mass moment of inertia Izz of the ball (10) when rotated about the second principal equatorial axis z, is less than 3.46% of the value of Iyy..
(FR) L'invention concerne un ballon de sport ovoïde gonflable équilibré dynamiquement (10) qui possède un axe polaire x, un premier axe équatorial principal y et un second axe équatorial principal z. Les axes x, y et z sont perpendiculaires entre eux et coïncident à une origine o, au centre géométrique du ballon. Le ballon (10) comporte une valve d'entrée d'air (11), pour permettre son gonflage, et au moins un élément de masse supplémentaire (12) conçu pour contrebalancer la masse de la valve (11). La valve d'entrée d'air (11) et chaque élément de masse supplémentaire (12) sont disposés de telle sorte que le centre de gravité du ballon (10) est sensiblement confondu avec l'origine o et que la différence entre le moment d'inertie de masse moyen Iyy du ballon (10) lorsqu'on le fait tourner autour du premier axe équatorial principal y et le moment d'inertie de masse moyen Izz du ballon (10) lorsqu'on le fait tourner autour du second axe équatorial principal z est inférieure à 3,46 % de la valeur de Iyy.
