  • Patent number: 6227981
    Abstract: The present invention contemplates an improved ball ramp assembly that enables even the most severely handicapped bowler to guide and accelerate a bowling ball toward the intended bowling pins. The bowling ramp assembly includes a ramp having a ball guide defining a ball path along the ramp, a base coupled to a proximal end of the ramp for supporting the ramp, a ball release coupled to the ramp for selectively controlling travel of the ball along the ramp, and a positioning assembly coupled to the ramp for adjusting the orientation of the ramp. The ball release includes a ball stopping member that moves between a ball blocking position and a ball releasing position. The positioning assembly includes at least one motor coupled to the ramp and a wheel located at the distal end of the ramp. The ball release and positioning assembly are both controlled by switches which may be located remotely from the ramp.
