ABSTRACT:
A remotely-controlled toy vehicle having a steering mechanism and driven by a dc motor selectively connected to a battery by a multi-position switch in a polarity which causes forward or reverse movement. Remote control is effected by a handset having first and second master diaphragm chambers linked through a flexible pneumatic line to first and second slave diaphragm chambers in the vehicle, one slave being operatively coupled to the steering mechanism and the other to the motor control switch. The handset is provided with a torsion bar having a handle, the bar being both swingable from side to side and also being rotatable. The bar is so coupled to the diaphragms of the master chambers whereby when the player swings the bar toward the left or right, this movement is pneumatically transmitted to the steering mechanism of the vehicle to cause the vehicle to turn toward the left or right. When the player rotates the bar clockwise or counter clockwise, this movement is pneumatically transmitted to the switch to cause the vehicle to travel in the forward or reverse direction.
