Abstract
A toy vehicle includes a generally rectangular hollow supporting chassis and a replica vehicle body pivotally secured to the chassis at the front portion. A return spring resiliently biases the rear portion of the truck body in a generally horizontal position. A battery power unit and electric motor are supported within the vehicle chassis and coupled to the vehicle wheels by a gear coupling mechanism. The gear coupling mechanism is engageable and disengageable by a shift lever extending upwardly from within the vehicle chassis to beyond the vehicle body. A sound unit includes a sound drum and a flexible reed supported closely thereto. A plurality of extending tabs within the drive gear system are operative upon motor rotation to flex and release the spring reed against the drum head sound unit to produce engine sounds. A heavy flywheel is coupled to the motor drive system and produces gradual slowdown when the motor is disengaged. An electric switch is interposed between the battery power unit and the motor and is operable by either pivotal motion of the truck body when the user presses downwardly upon or by the positioning of the shift lever in the engaged position.
