Electric generator for bicycles
First Claim
1. An electric generator assembly for supplying power to electrical devices on a bicycle, the bicycle having a frame and a wheel, the wheel having a hub axis, the generator assembly comprising:
- a gearwheel fixedly securable to the bicycle wheel along the hub axis of the bicycle wheel;
a rotor disposed at a distance from the hub axis of the bicycle wheel;
gear means for transmitting power between the rotor and the wheel so that the rotor is rotatable at a speed faster than that of the wheel, the gear means including an input pinion configured to mesh with the gearwheel; and
a gearbox for housing the gear means, the gearbox including means for pivotably connecting the gearbox to the rotor such that the input pinion is selectively engaged with and disengaged from the gearwheel by pivoting the gearbox relative to the rotor.

Abstract
An electric generator assembly for supplying power to electrical devices on a bicycle. The electrical generator assembly includes a gearwheel fixedly secured and rotatively coupled to a bicycle wheel proximate a hub axis of the bicycle wheel, a rotor housing, an annular stator disposed within the rotor housing, and a rotor disposed concentrically within the annular stator. The electric generator assembly further includes an arm extending from the rotor housing and configured for detachable attachment with a portion of the bicycle frame proximate the hub axis of the bicycle wheel. The rotor is driven by a rotor-driving gear disposed outside the rotor housing. The rotor-driving gear is configured to mesh with an output gear of a gear train for transmitting power from the bicycle wheel. An input pinion, configured to mesh with the gearwheel, is rotatively coupled to the input gear of the gear train. A gearbox, dimensioned to house at least the gear train and the rotor-driving gear, includes a pivot bearing for hingedly connecting the gearbox to the rotor housing, so that the input pinion can be selectively engaged with the gearwheel mounted to the bicycle wheel by selectively pivoting the gearbox relative to the rotor housing.
