Abstract
A drive mechanism for a toy vehicle. The drive mechanism connects a drive shaft of the vehicle to a driven wheel having an axis of rotation. It includes a first arm affixed to the vehicle drive shaft for rotation therewith. A second arm is affixed to the wheel axle for rotation with the axle. The first and second arms are pivotally connected together at a position offset from the drive shaft and the wheel axis. A spring biases the arms into an overlapping relationship in which, during normal rolling movement of the vehicle, the drive shaft is aligned with the driven wheel so that the wheel rotates about the axis of the drive shaft. A first stop is provided to engage the arms to limit rotation of the arms about their pivotal connection relative to each other in the direction of rotation of the wheel axle. A second stop engages the arms to limit rotation of the arms away from each other towards a fully extended position.
