Abstract

A plurality of rolling pontoons with or without a plurality of protrusions (paddles) and their use on amphibious vehicles and watercraft. The application of tires, power, suspension, paddle designs, towing apparatus, pontoon geometry and/or a plurality pontoon arrangements that will allow said vehicle to be towed without a trailer, easily and quickly traverse a variety of environments, and/or maneuver a variety ways. The further addition of electric motors, solar panels, and batteries allow efficient electric amphibious vehicle/watercraft and provide battery backup and power for a residence. A method of manufacture is defined with the modular application of said electrical drivetrain to new or existing amphibious vehicles or watercraft.

Claims

1. A rolling pontoon comprising an axis of rotation that has a transverse orientation to the direction of travel.

2. The rolling pontoons of claim 1 wherein:

one or more pontoons on and measured along the same rotational axes;

are greater than the average diameter of said pontoons on said rotational axis.

3. The rolling pontoons of claim 2 wherein:

one or more pontoons on and measured along the same rotational axes;

are greater than ½

of the vehicle width as measured along said rotational axis.

4. The rolling pontoons of claim 3 further comprising:

of protrusions (paddles) as part of said rolling pontoons;

or as one or more attachments such as tires to said rolling pontoons.

5. The rolling pontoons of claim 4 further comprising of protrusions that are angled from the direction of travel (not parallel or perpendicular) where said protrusions are typically perpendicular to the direction such as a typical paddlewheel.

6. The rolling pontoons of claim 4 further comprising of one or more road tires mounted on same rotational axis as said pontoons.

7. The rolling pontoons of claim 4 wherein said pontoons further comprise of radial shapes such as cylinders or discs or cones or bells or eggs or stars or helixes that rotate about the center of said radial shape.

8. A amphibious vehicle or watercraft comprising of a chassis with transversely oriented rolling pontoons of claim 3 mounted to said chassis.

9. The amphibious vehicle or watercraft and rolling pontoons of claim 8 further comprising the application of rotational energy such as electric motors or internal combustion engines connected to said rolling pontoons.

10. The amphibious vehicle or watercraft of claim 9 further comprising of electrical energy storage devices such as batteries or fuel cells affixed to chassis and electrically connected to said motors and engines.

11. The amphibious vehicle or watercraft of claim 10 further comprising of a method of use where:

the rolling pontoons with angled protrusions (paddles) of claim 5;

while in contact with a surface; and

applying differential rotational speeds and/or directions to 1 or more said rolling pontoons with said angled protrusions;

whereby said vehicle will have a range of motion relative to said surface that is perpendicular to parallel of the axis of pontoon rotation.

12. The amphibious vehicle or watercraft of claim 10 further comprising of rolling pontoons attached with a solid connection to the chassis (no suspension).

13. The amphibious vehicle or watercraft of claim 10 further comprising of rolling pontoons attached to the chassis with a flexible connection such as a typical automobile suspension.

14. A method of use for the amphibious vehicle or watercraft with rolling pontoons of claim 10 further comprising:

said vehicle with said pontoons rolling across a surface which is in motion relative to the amphibious vehicle or watercraft; and

the rolling pontoons are connected to an electrical generator or motor; and

said motors or generators electrical output is connected to an electrical storage device such as a battery; and

whereby electrical energy from said motor is stored in said electrical storage device.

15. The amphibious vehicle or watercraft with rolling pontoons of claim 10 further comprising of 2 or more pontoons where locating and mounting said pontoons to said chassis along the direction of travel of said vehicle are closer to the center of said chassis than the front or rear of said chassis such as a typical trailer wheel arrangement.

16. The amphibious vehicle or watercraft of claim 10 wherein said rolling pontoons are mounted closer to the outside corners of said chassis than the center of said chassis such as a typical land vehicle wheel arrangement.

17. The amphibious vehicle or watercraft of claim 10 further comprising of a retractable, removable, or fixed towing apparatus attached to said chassis.

18. The amphibious vehicle or watercraft of claim 10 further comprising of 2 or more transversely oriented pontoons mounted to said chassis.

19. The amphibious vehicle or watercraft of claim 10 further comprising of solar panels mounted to said chassis with electrical connections to said motors and said batteries.

20. The amphibious vehicle or watercraft of claim 19 further comprising of a direct current (DC) to alternating current (AC) converter mounted to said chassis and electrically connected to said solar panels, batteries and motors.

21. The amphibious vehicle or watercraft of claim 10 further comprising of a method of use where:

two or more said rolling pontoons;

with the application of differential rotational speeds and/or directions;

when in contact with a surface;

whereby the vehicle can change the direction of travel or steer along said surface.

22. The amphibious vehicle or watercraft of claim 10 further comprising of pontoons whose ends extend outward from forward mounted pontoons.

23. The amphibious vehicle or watercraft of claim 10 further comprising of pontoon arrangements whose diameters increase from forward mounted pontoons.

24. The amphibious vehicle or watercraft of claim 10 further comprising of a single rolling pontoon, battery, electric motor, electric motor controller with connecting wiring all attached to a chassis module such that multiple said chassis modules can be connected together.

25. The amphibious vehicle or watercraft with rolling pontoons of claim 10 further comprising of said rolling pontoons mounted to a sub chassis with a moveable attachment to said vehicle chassis that allows said rolling pontoons on said sub chassis to move forwards and backwards along said vehicle chassis.
