Roller skate with generator design
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.

Claims
I claim:
1. 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.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to a roller skate and more particular
to a roller skate with generator design to activate sound and
lighting circuitry.
[0003] 2. Description of the Prior Art
[0004] A traditional roller skate currently on the market uses a
generator to produce lighting effect, which comprises a permanent
magnet and an inductive coil, and lighting elements on the skate
connect to the inductive coil of the generator, thus when the
inductive coil rotates with respect to the permanent magnet,
according to the principle of the electric inductive, it generates
electric power to activate the lighting system. However, this
design uses the inductive coil and the magnetic ring to counter
rotate to generate electricity, which limits the lighting elements
to be on the wheels.
[0005] In view of this, the inventor has invented the present
invention to improve the shortcomings
SUMMARY OF THE INVENTION
[0006] It is the primary object of the present invention to provide
a roller skate with generator design, which produces sound and
lighting effect that is more attractive to consumers.
[0007] It is another object of the present invention to provide a
roller skate with generator design, which is more secure and lasts
long.
[0008] It is a further object of the present invention to provide a
roller skate with generator design, which is easy to install and
inexpensive in manufacture.
BRIEF DESCRIPTION OF THE DRAWINGS
[0009] FIG. 1 is an exploded view of the present invention;
[0010] FIG. 2 is a side view of FIG. 1 with partial sectioned;
and
[0011] FIG. 3 is a sectional view of FIG. 1.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0012] FIG. 1 shows a roller skate incorporated with the present
invention, which includes a coil base 1, a generator 2 and the
roller skate 3. The generator 2 is secured in the roller skate 3
and connected with a sound and lighting circuit 31 which comprises
LED and or whistles electronic parts (wherein this description uses
lighting elements as an example) and is secured by fasteners
311.
[0013] The generator 2 comprises a magnet ring 21 and an inductive
coil 22, by rotating the magnet 21 and the inductive coil 22 in an
opposite way, the inductive coil 22 shall produce electricity and
activate the sound and lighting circuit 31.
[0014] The coil base 1 comprises a hole 11 at the center, a pair of
fins 12 with fixation holes 121 extending from respective sides,
and a cover 13 to cover the inductive coil 3 in the coil base 1.
The cover 13 has a hole 131 for the magnet ring 21 to extend there
through.
[0015] The roller skate 3 has a pair of side plates 34 at the
bottom end thereof to secure wheels 32 and 33 thereat. A notch 341
is formed on one of the side plates 341 adapted to receive the coil
base 1 therein. One side of the wheel 33 has a wheel cover 4 which
has a pipe 41 extending from the center portion for a shaft 5 to
insert there through. The wheel cover 4 also comprises a number of
holes 42 for fasteners 43 to insert and secure the wheel cover 4 to
the wheel 33.
[0016] To assemble the present invention, as shown in FIGS. 2 and
3, the wheel cover 4 is inserted into the wheel 33 with the pipe 41
facing outwardly and secured by the fasteners 43, then the magnet
ring 21 of the generator 2 is sleeved onto the pipe 41, thus
forming an entire wheel 33. The inductive coil 22 is placed into
the coil base 1 and covered with the cover 13, the coil base 1 is
put onto the notch 34 of the wheel 33 whereas the fins 12 facing
and engaging with the outer surface of the side plate 34. The
wheels 32 and 33 are pivoted to the side plates 34 by inserting the
shafts 5 through the fixation holes 121 of the fins 12 and the hole
11 of the coil base 1, and finally secured with a sleeve 51 and
nuts 52 at the other end. Whereas the magnet ring 21 is inserted
into the inductive coil 22, thus when rolling, the magnet ring 21
secured on the wheel 33 shall rotate with respect to the inductive
coil 22 secured on the side plate 34, and the power generated will
go through the inductive coil 22 to the sound and lighting circuit
31.
