Title
(EN) BALL BLOCK ASSEMBLY FOR A PINBALL MACHINE
(FR) ENSEMBLE DE BLOCAGE DE BILLES POUR BILLARD ELECTRIQUE
Abstract
(EN)
A ball block assembly for maintaining control over rolling balls of the pinball machine during maintenance and servicing. Specifically, the pinball machine includes a playfield (23) mounted to a cabinet (22) and capable of supporting the rolling balls thereon. A ball trough (166) beneath the playfield is positioned to receive rolling balls exiting the playfield via a drain and to deliver the rolling balls back to the playfield via an aperture (170). When the playfield is tipped upwardly out of the cabinet for maintenance and servicing, rolling balls stored in the ball trough are maintained in the ball trough by the block assembly. That is, the ball block assembly prevents the rolling balls from falling out of the ball trough and into the cabinet. The ball block assembly preferably comprises a door (172) movable between an open position allowing the rolling balls to pass through the aperture and a closed position blocking the aperture to maintain the rolling balls in the ball trough. The door is disposed in the open position when the pinball machine is operational, while the door is disposed in the closed position when the playfield is tipped upwardly out of the cabinet for maintenance and servicing.
(FR)
La présente invention concerne un ensemble de blocage de billes conçu pour commander les billes roulantes du billard électrique lors des opérations d'entretien et de maintenance. Plus spécifiquement, ce billard électrique comprend une surface de jeu (23) montée sur un caisson (22), pouvant contenir les billes roulantes. Un distributeur de billes (166) placé sous la surface de jeu est conçu pour recevoir les billes roulantes en provenance de la surface de jeu par une distribution, et de les retourner à la surface de jeu par une ouverture (170). Lorsque la surface de jeu est soulevée en inclinaison par rapport au caisson pour des besoins de maintenance et d'entretien, les billes roulantes contenues dans le distributeur de billes demeurent là où elles sont grâce à l'ensemble de blocage. En effet, cet ensemble de blocage de billes empêche les billes roulantes de tomber du distributeur dans le caisson. De préférence, l'ensemble de blocage de billes comprend une porte (172) mobile entre une position ouverte qui permet aux billes roulantes de traverser l'ouverture, et une position fermée qui bloque l'ouverture afin de maintenir les billes dans le distributeur. Cette porte est en position ouverte lorsque le billard électrique est opérationnel, alors qu'elle est en position fermée lorsque la surface de jeu est soulevée en inclinaison par rapport au caisson, pour des besoins d'entretien et de maintenance.
