  • Blocking toy vehicle
    Patent number: 4223476
    Abstract: A toy vehicle having collectors thereon which are adapted to contact conductive strip's along a track is adapted to move at a substantially constant speed and provided with first and second guide means projecting laterally with respect to the vehicle body at spaced locations thereon. Each guide means terminates in a free end projecting downwardly for entry into a groove. Said guide means and groove cooperate to guide the vehicle around turns in the track. The guide means free ends and the grooves have a width differential which is less the width differential between each collector and its conductive strip. The guide means are mounted so that they may be mounted to project to one or to the other side of the vehicle.
