摘要：The prent invention contemplates an improved ball ramp asmbly that enables even the most verely handicapped bowler to guide and accelerate a bowling
ball toward the intended bowling pins. The bowling ramp asmbly includes a ramp having a ball guide defining a ball path along the ramp, a ba coupled to a proximal end of the ramp for supporting the ramp, a ball relea coupled to the ramp for lectively controlling travel of the ball along the ramp, and a positioning asmbly coupled to the ramp for adjusting the orientation of the ramp. The ball relea includes a ball stopping member that moves between a ball blocking position and a ball releasing position. The positioning asmbly includes at least one motor coupled to the ramp and a wheel located at the distal end of the ramp. The ball relea and positioning asmbly are both controlled by switches which may be located remotely from the ramp.
