Self-returning toy vehicle
摘要:
A toy vehicle which when propelled by a player from a starting point along a flat surface in the forward direction, acts to store energy, the vehicle at the end of its forward run being caused by the stored energy to reverse its orientation as it runs back toward the starting point. The vehicle includes a chassis having a front cowl section projecting therefrom below which is a front wheel carriage coupled to the cowl by a pivot pin, whereby the carriage orientation is reversible relative to the cowl. The carriage has a spring motor therein operatively coupled to the front wheel axle which when rotated during the forward run of the vehicle acts to wind the motor. The rear wheel axle is supported in bearings below the rear section of the chassis, one of which is slotted to permit angular displacement of the axle. At the end of the forward run, the energized motor then acts to drive the front wheel carriage in the reverse direction to cause angular displacement of the rear axle, as a result of which the chassis swings in an arc to assume a position behind the front wheel carriage as it returns toward the starting point.
