ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a skateboard, and more particularly to a self-generating light-producing skateboard including at least one induction coil assembly, at least one magnet-containing wheel mounted at an outer side of the induction coil assembly, at least one light-emitting element fixed to the an outer periphery of a deck of the skateboard and electrically connected to the induction coil assembly, and a light-transferring strip mounted around the outer periphery of the deck. The light-transferring strip is provided along an outer surface with spaced frosted, grooved, and ribbed portions to reflect and refract lights emitted from the light-emitting element. The induction coil assembly may also be connected to other electric-energy consuming optional attachments of the skateboard to omit batteries.
BACKGROUND OF THE INVENTION
Most conventional skateboards do not include current and light generating means. It is dangerous to play with skateboards without light-emitting warning means, particularly when playing with them in dark places.
It is therefore desirable to develop a self-generating light-producing skateboard to eliminate drawbacks existing in the conventional skateboards.
SUMMARY OF THE INVENTION
A primary object of the present invention is to provide a self-generating light-producing skateboard that does not need batteries but can automatically produce current to drive light-emitting elements on the skateboard for the same to emit light as a warning to other players.
Another object of the present invention is to provide a self-generating light-producing skateboard that uses a light-transferring strip mounted around an outer periphery of the skateboard to transfer light-emitting from light-emitting elements at separated points to the entire periphery of the skateboard. The light-transferring strip is provided with spaced frosted, grooved, and ribbed portions to reflect and refract light and therefore advantageously reduces the number of light-emitting elements.
A further object of the present invention is to provide a self-generating light-producing skateboard that may include electronic, electric-energy consuming optional attachments to be driven by current automatically generated by the induction coil assembly without using any battery.
