Abstract

A power generation device includes a body, an electric generator, a hub, and an arm. The body extends from a first end to a second end and a longitudinal axis extends from the first end to the second end. The electric generator is housed within the body and includes a rotor. The hub is coupled to the body at the first end and is rotatable with respect to the body about the longitudinal axis. The arm extends from the hub such that the arm is rotatable with the huh about the longitudinal axis. The arm is pivotably coupled to the hub such that arm is pivotable with respect to the hub about a pivot axis that is non-collinear with the longitudinal axis. Rotation of the hub and the arm about the longitudinal axis causes rotation of the rotor of the generator to generate electrical power.

Dependent claims

A portable power generation device, comprising:

a body extending from a first end to a second end, the body configured to be held in a hand of a user, wherein a longitudinal axis extends from the first end to the second end;
an electric generator housed within the body, the generator including a rotor;
a hub coupled to the body at the first end and rotatable with respect to the body about the longitudinal axis;
an arm extending from the hub such that the arm is rotatable with the hub about the longitudinal axis, wherein the arm is pivotably coupled to the hub such that the arm is pivotable with respect to the hub about a pivot axis that is non-collinear with the longitudinal axis;
and
a knob coupled to the arm at an end of the arm opposite the hub, wherein the knob is rotatable with respect to the arm about an arm longitudinal axis that extends from a first end of the arm to a second end of the arm;
and
wherein rotation of the hub and the arm about the longitudinal axis causes rotation of the rotor of the generator to generate electrical power.
