  • Anti-collision toy vehicle playset
    Patent number: 4993985
    Abstract: A children's toy car playset contains at least two toy cars, suitably containing low friction wheel and axle structures. Each of the cars contains an anti-collision device that in normal play prevents collisions between the cars, irrespective of the angle of approach at which one of the cars moves toward an other. Suitably the anti-collision device is formed by a permanent magnet with the magnetic fields oriented so that the field lines extend downwardly at least about the periphery of the car.
