Abstract

La présente invention concerne un appareil d'enseignement du service au tennis qui comporte une plaque de base (1) supportant le montant principal et son système hydraulique (2). Celui-ci est complété par des renforts verticaux (3). L'appareil comporte également une pompe hydraulique (6) et un réservoir d'huile (7) ainsi qu'un logement de câble (24a) servant à ranger le surplus de câble d'alimentation (25) assurant l'alimentation électrique de la boîte de distribution (24) et du moteur électrique (9). La plate-forme de service (5) est montée sur les renforts verticaux (3), des barreaux horizontaux (4a) formant une échelle d'accès (4) à la plate-forme de service (5). Plusieurs organes sont fixés sur un plateau de montage installé au sommet d'un montant mobile à l'intérieur du montant principal et de son système hydraulique (2). Parmi ces organes, on compte le moteur électrique (9) ainsi que le rotor (10), le contrepoids (29), le bac à balles (11) et un bras de transfert (12) aboutissant à l'orifice d'alimentation en balles (13). L'indicateur de cible de balles (17) ainsi que le radar (16) sont disposés dans un volume libre de l'orifice d'alimentation en balles (13). Un dispositif de suspension de balle (15) retenant la balle (31) pend d'un câble (30) situé sous l'ouverture d'alimentation en balles (13). Une barre à déflecteurs (23) équipant le bras de transfert, comporte au-dessus de l'orifice d'alimentation en balles (13) des panneaux déflecteurs (22), une barre d'indicateurs (19) se présentant parallèlement sur le côté opposé. Celle-ci est équipée d'un indicateur mobile de lancer de balle (20) et d'un indicateur de toucher de balle (21). La barre d'indicateurs (19) est fixée à la face inférieure du plateau de support (18) du bras de transfert (12). Le système électronique d'évaluation et la commande informatisée sont montés entre les montants supports (3), constituant ainsi un ensemble à ordinateur (26), panneau de commande (27) et écran d'affichage (28).
