  • Magnetic toy vehicle and track
    Patent number: 5931714
    Abstract: A track comprises a base and two sidewalls. At least one toy vehicle comprises an underside and two sides. Magnets attached to the track and to the vehicle repel the underside of the vehicle from the base of the track, and repel the sides of the vehicle from the sidewalls of the track; thus, the vehicle floats above the base and between the sidewalls of the track. The vehicle moves along the track due to gravitational force applied to the vehicle, and alternatively due to motive force applied to the vehicle by a pair of rotating drums.
