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 22):
An apparatus for providing a gyroscopically-responsive power assist to a user for carrying a load, comprising:\n a frame support; an elongated wheel support member coupled transversely across the frame support along a horizontal axis that is perpendicular to a longitudinal axis of the frame support, wherein the frame support rotates about the horizontal axis at a pivot point of the elongated wheel support member; a first and a second wheel rotatably mounted substantially perpendicular to the horizontal axis, the first and second wheels being coupled to the elongated wheel support member, and extending at least partially below the frame support; a motor to drive at least the first wheel when energized; a sensor; and a gyroscopic fore-and-aft balance control system configured to output an energized signal which controls whether power is being provided to energize the motor, wherein the balance control system deactivates the motor using the energize signal after sensing, by the sensor, a rotational force applied to the frame support about the pivot point, and wherein the balance control system activates the motor using the energize signal after sensing, by the sensor, a longitudinal force applied to the frame support and instructs the motor to accelerate or decelerate at least the first wheel in accordance with the direction and magnitude of the longitudinal force applied to the frame support.
