Abstract

An inertia motor for use in toys, comprising a drive gear mounted on one of the axles of the vehicle and having a substantial diameter and rotating a pinion gear which is coaxially mounted with a substantially larger back gear, which in turn drives a pinion which is coaxial with a flywheel, the flywheel being mounted eccentrically with respect to the drive shaft. The flywheel is of such size and weight, and the gear ratios are such that the flywheel is rotated at least about twenty times with each rotation of the drive gear and, therefore, stores a substantial amount of energy which is slowly released from the flywheel to the drive gear to provide a slow, prolonged release of energy to drive the vehicle. In one embodiment of the invention, a pair of gear trains are provided, one on each side of the flywheel, in mirror image to each other, and the housing therefor, which may contain only two wheels, is in a substantially eliptical shape having a flattened bottom. In this latter form, the device may be used alone as an inertia motor-driven toy, capable of gyroscopic action when placed on one of its two wheels and capable of being inserted in a second toy having a suitable enclosure o…
