Abstract

See full text

A manually powered hand held electrical device such as a flashlight is provided. The device has an elongate housing, a power-requiring functional element, a hinge element at the back of the housing, and a crank arm having an end rotatably attached to the hinge. The hinge allows the crank arm to rotate within an arc of 270 degrees between a resting position and an operating position. The arc is within a plane that includes the longitudinal axis of the housing. In the resting position, the crank arm is parallel to the housing; in the operating position, it is orthogonal thereto. The hinge is rotatable about the longitudinal axis of the housing, and consequently so too is crank arm. The hinge is connectable to a generator; rotation of the hinge element powers the generator, and the generator provides power to the power-requiring functional element such as a light-emitting element.
