Abstract
An inertia motor especially--but not exclusively--for a toy vehicle. A rear wheel axle extends through the housing and has a drive gear mounted thereon to turn unitarily therewith. A flywheel is rotatably mounted on the housing for spinning to store or to payout energy. First and second gear trains extend between the drive gear and flywheel. A movable control lever carries first and second movable gears, one of the movable gears being an idler mounted on and movable with a shaft which passes through a pair of oppositely disposed arcuate slots, the other movable gears being mounted on a shaft journaled in the lever arm. The arcuate slots are located so that the idler gear meshes with one of the gear trains when the lever arm is in one of its two positions. The teeth on the meshing gears dynamically pull the shaft to one end of the arcuate slots and into the one gear train when the drive gear is driving and pushing the shaft to the other end of the arcuate slots to eject the idler from the one gear train when the flywheel is driving. The journals for the shaft of the other movable gear are located on the lever arm so that the other movable gear meshes with the other of the gear trains when the lever arm is in the other of its two positions. The arcuate slots are part of molded plastic parts which may be made with the precision of the mold, thereby improving performance and reducing wear from poor tolerances used heretofore.
