Abstract

A method of propelling a wheeled platform, which includes creating a source of energy upon a first change in orientation of the platform relative to an axle housing of the wheeled platform by rotating the platform around an axis approximately parallel to a longitudinal axis of the platform. The source of energy is stored and released to propel the wheeled platform.

Claims

1. A method of propelling a wheeled platform comprising the steps of:

creating a source of energy upon a change in orientation of the platform around an axis approximately parallel to a longitudinal axis of the platform and wherein the platform rotates around the axis;

storing the source of energy; and

releasing the source of energy to propel the wheeled platform by converting the source of energy into a rotational force to drive at least one wheel of the wheeled platform.

2. The method of claim 1, wherein creating the source of energy is created as a result of a first movement of a pair of trucks relative to one another, and releasing the source of energy by a second movement of the trucks relative to one another.

3. The method of claim 1, wherein the source of energy is released to a hydraulic motor, wherein the hydraulic motor is configured to propel the wheeled platform.

4. The method of claim 1, further comprising step of storing the source of energy in one or more energy storage elements, and wherein the energy storage elements include at least one of the following:

a spring, a compressed or pressurized gas, an elastic material, a battery, or a hybrid combination of one or more of the energy storage elements.

5. The method of claim 1, further comprising step of releasing the source of energy from one or more energy storage elements, wherein the one or more energy storage elements comprises a ratchet system which engages the storing of energy when the platform is rotated in one direction and which disengages the storage of energy from the movement of the platform when the platform rotates in the opposite direction, and which releases the energy to one or more mechanisms to propel the wheeled platform.

6. The method of claim 1, further comprising step of releasing the source of energy from one or more energy storage elements, wherein the one or more energy storage elements comprises a mechanical or electronic toggle system, which engages the storing of energy when the platform is rotated in one direction and which disengages the storage of energy from the movement of the platform when the platform rotates in the opposite direction, and which releases the energy to one or more mechanisms to propel the wheeled platform.

7. The method of claim 1, further comprising step of releasing the source of energy from one or more energy storage elements, wherein the one or more energy storage elements comprises an electronic sensor and switching system which releases the energy to one or more mechanisms to propel the wheeled platform when the platform rotates around its rotational axis in a programmed response to some movement of the platform relative to a truck assembly.

8. The method of claim 1, further comprising step of releasing the source of energy from one or more energy storage elements, wherein the one or more energy storage elements comprises a pneumatic or hydraulic control valve system which engages the storing of energy when the platform is rotated in one direction and which disengages the storage of energy from the movement of the platform when the platform rotates in an opposite direction, and which releases the energy to one or more mechanisms to propel the wheeled platform.

9. The method of claim 1, wherein the source of energy is released to a pneumatic motor, wherein the pneumatic motor is configured to propel the wheeled platform.

10. The method of claim 1, wherein the source of energy is released to a electric motor, wherein the electric motor is configured to propel the wheeled platform.

11. The method of claim 1, wherein the source of energy is released to a mechanical drive train, wherein the mechanical drive train is configured to propel the wheeled platform.

12. The method of claim 1, wherein the source of energy is released to a hybrid mechanism which may include hydraulic, pneumatic, electric, electronic, mechanical, internal combustion elements, wherein the hybrid mechanism is configured to propel the wheeled platform.

13. The method of claim 1, wherein the wheeled platform comprises:

a platform;

a pair of trucks, each truck being adapted to be attachable to the platform and comprising at least one axle configured to receive a wheel; and

at least one wheel attached to the at least one axle of each truck.

14. The method of claim 1, wherein the change in orientation of the platform relative to the axle housing of the wheeled platform results in a turning response of the wheeled platform.

15. A method of propelling a wheeled platform comprising the steps of:

creating a source of energy upon a change in orientation of the platform around an axis approximately parallel to a direction of rolling motion of the platform and wherein the platform rotates around the axis;

storing the source of energy; and

releasing the source of energy to propel the wheeled platform by converting the source of energy into a rotational force to drive at least one wheel of the wheeled platform.

16. The method of claim 15, wherein the change in orientation of the platform relative to the axle housing of the wheeled platform results in a turning response of the wheeled platform.
