Abstract
Kicker apparatus for a pinball machine having an inclined playing surface, comprises a kicker and mechanism for triggering the kicker to strike a ball and drive the ball up the inclined playing surface. The kicker is disposed in a triangular aperture in the playing surface, two of whose sides converge in the direction in which the ball is projected by the kicker, thereby to direct the ball without the need for upstanding guide members. The triangular aperture is closed from beneath by a plate that is mounted for downward movement under the weight of the ball as the ball rolls down into the triangular aperture by gravity, the plate actuating the triggering mechanism for the kicker.
Claims5
In kicker apparatus for pinball machines, comprising an inclined playing surface, a kicker for being contacted by a ball which rolls down said playing surface under the influence of gravity, a plate which is depressed by the weight of a ball approaching said kicker, and actuating means to actuate said kicker to impel the ball backward upon said plate being depressed;
- the improvement comprising an aperture in the playing surface, the aperture having opposite side edges on which the ball rolls in its movement toward and away from the kicker, said edges diverging from each other in the direction of movement of the ball toward the kicker and converging toward each other in the direction of movement of the ball away from the kicker, said plate being located in said aperture, and spring means interconnecting said kicker and plate to urge said kicker backward and said plate upward.
In a surface ball rolling apparatus including a playing surface and kicker apparatus for striking a ball which rolls down said playing surface under the influence of gravity;
- the improvement comprising an aperture in the playing surface having a V-shape with opposite side edges which diverge from each other downwardly towards said kicker, an L-shaped kicker pivotally mounted by the corner thereof and having a vertical portion projecting above said playing surface through said aperture and a horizontal portion below the aperture, actuating means being connected with a part of said horizontal portion to move said kicker forward to strike the ball upon actuation thereof, a plate located in said aperture and adapted to be depressed by the weight of said ball rolling down toward said kicker, switching means for detecting said depression of plate to actuate said actuating means, spring means interconnecting said plate and kicker to urge said plate upward and said kicker backward, and a bracket supporting said kicker and plate swingably and said actuating means rigidly.
