Abstract: |
A remote controlled self-propelled toy vehicle is disclosed which is capable of moving on a solid support surface and also on water. Two motors and a power source are mounted to the hull of the toy vehicle. Each motor drives, through a suitable transmission assembly, a drive wheel and a screw propeller. The drive wheels are disposed to come into contact with the solid support surface for operation as a land going vehicle, and the screw propellers are disposed for submersion in water when the toy vehicle is operated as a boat. Steering of the vehicle is accomplished on the solid surface and also on water by varying the power output of the motors so that uneven power output of the two motors causes the vehicle to turn. A suitable, preferably radio signal emitting remote control system and associated circuitry is provided to allow a player to steer the vehicle from a remote location.

First Claim:
Show all 12 claims |
What is claimed is:
1. A steerable self-propelling toy vehicle capable of moving on a solid support surface and on water, the vehicle comprising:
- a hull having sufficient buoyancy to keep the vehicle afloat on water, and having a general longitudinal axis;
- a first variable speed motor and a second variable speed motor incorporated in the hull;
- a first and second axle connected respectively to the first and second motor and extending at inclined angles to the longitudinal axis;
- a power source operatively connected to the first and second motors;
- a first and second wheel mounted to the hull for driving the vehicles on the solid support surface when the vehicle is operated as a land going vehicle, the first wheel being positioned offset to one side of the vehicle relative to the general longitudinal axis of the hull and being operatively connected to the first axle of the first motor to be driven thereby, the second wheel being positioned offset to the other side of the vehicle relative to the general longitudinal axis of the hull and being operatively connected to the second axle of the second motor to be driven thereby;
- a first screw propeller and a second screw propeller mounted to the hull for contact with water when the vehicle is operated on water, the first screw propeller being positioned offset to one side of the vehicle relative to the general longitudinal axis of the hull and operatively connected to the first axle of the first motor to be driven thereby, the second screw propeller being positioned offset to the other side of the vehicle relative to the general longitudinal axis of the hull, and operatively connected to the second axle of the second motor to be driven thereby, the first and second screw propellers are positioned to provide respective thrust force vectors which converge and substantially cross one another outside of the hull and behind the vehicle, and
- control means operatively connected to the power source and the first and second motors for continuously and differentially varying, at the option of an operator, the levels of power supplied from the power source respectively to the first and second motors to vary the relative rotation of respectively the first and second wheels and the first and second screw propellers whereby the operator steers the vehicle both on the solid surface and on water by manipulating the control means to drive a predetermined wheel or screw propeller at a greater relative rotational speed to effectuate steering.
