Abstract:
A gyroscopically-responsive power assisted moment arm is disclosed for use in connection with vehicles such as load carrying devices. A moment arm extends to a pivot point such that when a longitudinal force is applied at the moment arm, a sensor senses such force and outputs an energizing signal to a motor to drive a wheel. If a rotational or vertical force is applied to the moment arm, the motor need not be driven. According to the invention, therefore, a power assist can be provided to a user to drive a wheel in a desired direction of transport while not causing drive during tipping or unloading of the load carrying portion of the vehicle. Such an apparatus can be advantageously applied to a power assisted wheelbarrow, as one exemplary application.

Claim (Index 34):
An apparatus for providing a power assist, comprising:\n a moment arm component disposed along a longitudinal axis, having a proximal end and a distal end; a pivot coupled to a distal end of the moment arm component, wherein at least a portion of the moment arm component rotates along a first rotational axis about the pivot; a wheel rotatably mounted about a second rotation axis, the wheel being coupled with the pivot, and extending at least partially below of the moment arm component; a motor to drive the wheel when energized; one or more sensors configured to sense a longitudinal force applied substantially along the longitudinal axis and configured to sense a rotational force applied about the pivot; and a control system configured to output an energize signal which controls whether power is being provided to energize the motor, wherein the control system deactivates the motor using the energize signal after sensing, by the one or more sensors, a rotational force applied to the moment arm component about the pivot, and wherein the control system activates the motor using the energize signal after sensing, by the sensor, a longitudinal force applied to the moment arm component and instructs the motor to accelerate or decelerate the wheel in accordance with the direction and magnitude of the longitudinal force applied to the moment arm component.
