Abstract

An assembly for a wheeled platform includes a platform element adapted to be attachable to a platform and a housing adapted to receive the platform element, wherein a change in a contact point of the platform element relative to the housing results in a turning response of the wheeled platform.

Claims

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

creating an accumulated source of energy upon a first 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, and wherein the accumulated source of energy created to rotate the platform around its longitudinal axis is primarily stored and accumulated and not instantaneously transferred into driving at least one wheel of the wheeled platform, and wherein the accumulated source of energy does not directly drive the at least one wheel of the wheeled platform upon the first change in orientation of the platform around the longitudinal axis of the platform;

storing the accumulated source of energy;

distributing the accumulated source of energy upon sensing a second change in orientation of the platform around the longitudinal axis by converting the accumulated source of energy into a rotational force to drive at least one wheel of the wheeled platform; and

controlling a distribution of the accumulated source of energy to propel the wheeled platform in response to the change in orientation of the platform.

2. The method of claim 1, further comprising steps of sensing a rate of change in orientation of the platform and distributing energy from the accumulated source of energy to propel the wheeled platform as a function of the rate of change in orientation of the platform.

3. The method of claim 1, further comprising steps of sensing an amount of change in orientation of the platform and distributing energy from the accumulated source of energy to propel the wheeled platform as a function of the amount of change in orientation of the platform.

4. The method of claim 1, further comprising steps of sensing a duration of change in orientation of the platform and distributing energy from the accumulated source of energy to propel the wheeled platform as a function of the duration of change in orientation of the platform.

5. The method of claim 1, further comprising steps of sensing the first and second change in orientation of the platform around the longitudinal axis of the platform by sensing the movement of a pair of trucks relative to one another.

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

7. 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.

8. The method of claim 7, further comprising at least one sensor, which senses the change in orientation of the platform element.

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

10. The method of claim 1, further comprising steps of sensing the first and second change in orientation of the platform element with at least one sensor, and wherein a signal from the at least one sensor controls the distribution of the accumulated source of energy to propel the wheeled platform.

11. The method of claim 1, wherein the step of storing the accumulated source of energy is such that the accumulated source of energy generated is not directly converted into the propulsion of the wheeled platform upon the first change in orientation of the platform.

12. The method of claim 1, wherein the accumulated source of energy is generated upon the first 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.

13. A method of propelling a wheeled platform comprising steps of:

distributing energy from an accumulated 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;

sensing a change in orientation of the platform around the longitudinal axis of the platform;

controlling a distribution of the accumulated source of energy to propel the wheeled platform in response to the change in orientation of the platform; and

wherein the accumulated source of energy is released to an electric motor, and wherein the electric motor is configured to propel the wheeled platform.

14. The method of claim 13, further comprising steps of sensing a rate of change in orientation of the platform and distributing energy from the accumulated source of energy to propel the wheeled platform as a function of the rate of change in orientation of the platform.

15. The method of claim 13, further comprising steps of sensing an amount of change in orientation of the platform and distributing energy from the accumulated source of energy to propel the wheeled platform as a function of the amount of change in orientation of the platform.

16. The method of claim 13, further comprising steps of sensing a duration of change in orientation of the platform and distributing energy from the accumulated source of energy to propel the wheeled platform as a function of the duration of change in orientation of the platform.

17. The method of claim 13, further comprising steps of sensing the change in orientation of the platform around it longitudinal axis indirectly by sensing the movement of a pair of trucks relative to one another.

18. A method of propelling a wheeled platform comprising steps of:

distributing energy from an accumulated 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;

sensing a change in orientation of the platform around the longitudinal axis of the platform;

controlling a distribution of the accumulated source of energy to propel the wheeled platform in response to the change in orientation of the platform; and

wherein the accumulated source of energy is comprised of at least one of the following energy storage elements;

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

19. A method of propelling a wheeled platform comprising steps of:

distributing energy from an accumulated 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;

sensing a change in orientation of the platform around the longitudinal axis of the platform;

controlling a distribution of the accumulated source of energy to propel the wheeled platform in response to the change in orientation of the platform; and

releasing energy from the accumulated 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 movement of the platform relative to a truck assembly.

20. The method of claim 19, wherein the energy released from the accumulated source of energy is released to a hybrid mechanism, which may include hydraulic, pneumatic, electric, electronic, mechanical, internal combustion elements, and wherein the hybrid mechanism is configured to propel the wheeled platform.
