Special effects drive mechanism for self-propelled toy vehicles

摘要: A unique drive mechanism for a toy vehicle is disclosed which can be selectively enabled to cause the come an abrupt halt after powered run, and realistically imitate "spin out" of full scale vehicle. The train includes first gear directly rotated by coiled spring, second coupled in driving engagement with vehicle's wheels, third shiftable between engaged position coupling gears, cleared wherein rotate independently gear. locked its pivotal, gravity biased locking mechanism. selective, first, gears causes coil spring has fully unwound at completion run.
