Abstract

A roller skate with generator design comprises a coil base and a generator, in general, wherein the roller skate has a sound and lighting circuit connected to the generator, a pair of side plates pivoted with wheels underneath the roller skate, the principle of generating electric power is to counter rotate a magnetic ring and an inductive coil, wherein the coil base comprises a cover and a pair of fins extending from respective sides, and a wheel has a wheel cover extending a pipe at its center for a shaft to insert there through and is adapted to secure the magnetic ring thereon, by securing the two fins onto the side plates of the roller skate with shafts, the coil base is also secured thereon, whereas the pipe will be inserted into the coil base with the magnetic ring inserted into the inductive coil, so that when rolling the roller skate, the magnetic ring rotates with respect to the inductive coil and generates electric power.

Dependent claims

A roller skate with generator design comprising a coil base and a generator, wherein said roller skate providing a sound and lighting circuit connected to said generator, and a pair of side plates pivoted with wheels underneath of said roller skate, by rotating a magnet ring with respect to an inductive coil to generate electric power and supply to said sound and lighting circuit, and being characterized in that

said coil base comprising a cover and having extended a pair of fins from respective sides, said cover comprising a hole for said magnet ring to insert there through,
one of said side plates of said roller skate comprising a notch, and a wheel with respect to said notch having a wheel cover, said wheel cover having extending a pipe therefrom, adapted for a shaft to insert there through, and being secured with said magnet ring thereon, and whereas
by placing said inductive coil into said coil base and sealed with said cover, and insert into said notch of said side plate, secure said fins onto said side plate, and insert said pipe into said inductive coil, whereas said magnet ring being located in said inductive coil, thus when rolling said roller skate, said magnet ring rotates with respect to said inductive coil to generate electric power.
