摘要： An inclined, flat, surfaced ramp to simplify and accelerate learning to juggle. One or more balls are rolled up and down the ramp rather than tossed freely in the air. Rolling makes the balls move more slowly and gives the user more control over their trajectory. The angle of the ramp is increased as the user's skill level improves, causing the balls to roll faster, until free-fall speed is achieved and the training aid is no longer needed. Inscribed or printed patterns on the Base Board [1] or Rolling Surface [2] show a recommended pattern for the ball's trajectory. Ramp may have Retaining Ledges [4] at top and/or bottom to keep balls from rolling off the ends of the board. Base Board may be fabricated in sections and optionally hinged in the middle to allow it to fold for easier carrying and storage.
