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.
Claims4
A toy comprising:
- a. a track comprising a first magnet means attached thereto;
- b. at least one vehicle comprising a second magnet means attached thereto;
- c. the first magnet means configured to repel the second magnet means such that the vehicle floats above the track;
- d. the first magnet means comprising at least two series of first magnets, each of the series of first magnets disposed longitudinally along the track, the at least two series of first magnets disposed in generally parallel relationship to each other;
- and
- e. the second magnet means comprising:
- i. a first pair of second magnets disposed on an underside of the vehicle near a front end of the vehicle and arrange such that a geometric line passing through centers of each of the second magnets of the first pair of second magnets is perpendicular to a longitudinal axis of the vehicle;
- ii. a second pair of second disposed on the underside of the vehicle near a rear end of the vehicle and arrange such that a geometric line passing through centers of each of the second magnets of the second pair of second magnets is perpendicular to the longitudinal axis of the vehicle;
- iii. the underside of the vehicle being devoid of magnets between the first and second pairs of second magnets;
- and
- iv. the first pair of second magnets and the second pair of second magnets configured such that each of the second pair of second magnets aligns directly over a gap between the first magnets when each of the first pair of second magnets aligns directly over one of the first magnets.
