(FR) APPAREILLAGE POUR LA PRATIQUE DU VOLLEY-BALL
Abstract: front page image
(EN)A device for the automatic projection of a plurality of volley balls (136). A tiltable magazine (146) feeds the volley balls (136) to the projecting device (96). The device is motor operated and overcomes the prior art problem by not being slow and not having to rely on manual operation, by the use of a rotating cam (72) that acts a spring biased ball impacting arm (78). The device also overcomes the prior art problem of not being adapted to vary the velocity of the ball to be projected and the trajectory of the ball being projected. This lastly mentioned problem is overcome by the use of a pivoted locking member (30) that permits the pivoting of the projecting device and the locking of the device in a desired position.
(FR)Dispositif pour la projection automatique d"une pluralite de balles de volley (136). Un magasin inclinable (146) alimente le dispositif de projection (96) en balles de volley (136). Le dispositif est mis en action par un moteur et resoud les problemes de la technique anterieure par sa rapidite et par l"utilisation d"une came rotative (72), qui supprime la necessite d"un fonctionnement manuel (72) qui agit qui agit sur un bras, rappele par un ressort, d"impulsion de la balle (78).
