  • Gravity-powered toy vehicle with dynamic motion realism
    Patent number: 6602107
    Abstract: A gravity-powered toy vehicle, such as a model roller coaster, with an energy-storing flywheel coupled to the wheels to reduce the vehicle velocity s it approaches that which is proportionately realistic for the model scale. The initial potential energy of the vehicle is mostly conserved over the course of the track just as with a real roller coaster. At all points on the track the velocity of the model vehicle is reduced by a constant proportion compared to an unrestrained free-fall vehicle. Thus the dynamic velocity profile of the toy vehicle is the same as for a full size vehicle throughout its descending and ascending journey, but at a proportionately reduced speed.
