Abstract:
1. Speed controller for toy vehicles on electrically conducting tracks of a toy car racetrack, comprising a controller for varying an electric driving voltage from an electric power supply for the tracks of the toy car racetrack, the controller for varying the electric driving voltage including an input manually movable along a predetermined operating path and being constructed for varying the driving voltage supplied by the electric power supply along the operating path from zero to a first predetermined maximal value below the voltage supplied by the electric power supply, an additional controller including an input for manually setting the driving voltage at the tracks of the toy car racetrack to a second predetermined value above the driving voltage maximally supplied by the controller for varying the electric driving voltage, the second predetermined value corresponding to a voltage higher than the voltage output of the electric power supply, and an energy accumulator for supplying, during the manual operation of the additional controller, power to the car racetrack in addition to the power supplied by the electric power supply.
