SUMMARY OF THE INVENTION
The present invention seek to provide an improved toy vehicle which has an extremely high degree of flexibility and versatility.
There is thus provided in accordance with a preferred embodiment of the present invention a toy vehicle including at least one forward wheeled axle, at least one rearward wheeled axle and a resilient coupling connecting the at least one forward wheeled axle and the at least one reward wheeled axle with more than one degree of freedom therebetween.
Preferably, the resilient coupling includes an elongate springs.
In accordance with a preferred embodiment of the present invention, the resilient coupling includes a coil spring extending when in a rest orientation, generally perpendicular to the at least one forward wheeled axle and to the at least one rearward wheeled axle.
Preferably, the toy vehicle is operative for wheeled translation both in a first orientation and in a second orientation upside down of the first orientation.
In accordance with a preferred embodiment of the present invention, each of the at least one forward wheeled axle and the at least one rearward wheeled axle includes a pair of wheels, each wheel being independently controllable.
Preferably, each wheel is associated with a separate motor, thereby providing steering of the vehicle by individual speed control of the wheels.
In accordance with a preferred embodiment of the present invention, at least one of the at least one forward wheeled axle and at last one rearward wheeled axle is a non-rigid axle.
Preferably, the resilient coupling connecting the at least one forward wheeled axle and the at least one rearward wheeled axle has more than two degrees of freedom therebetween.
More preferably, the resilient coupling connecting the at least one forward wheeled axle and the at least one rearward wheeled axle has more than three degrees of freedom therebetween.
Even more preferably, the resilient coupling connecting the at least one forward wheeled axle and the at least one rearward wheeled axle has more than four degrees of freedom therebetween.
Yet more preferably, the resilient coupling connecting the at least one forward wheeled axle and the at least one rearward wheeled axle has more than five degrees of freedom therebetween.
Still more preferably, the resilient coupling connecting the at least one forward wheeled axle and the at least one rearward wheeled axle has more than six degrees of freedom therebetween.
