Electrically blinking hula-hoop
Abstract
An electrically blinking `Hula-Hoop` is comprised of; 1) eight
pieces of flexible tubes of transparent material, 2) eight pieces
of the tube connectors, 3) a blinking lightning circuit comprised
of one or two electric wires, plurality of LEDs connected to the
electric wire, and one blinking connector that is activated by a
liquid metal/metal ball positioned therein, 4) a power switch on a
circuit board, 5) two `AAA` size 1.5 Volt batteries. Any motion
including a rotational motion of the `Hula-Hoop` connects and
disconnects the blinking connectors and enables the LEDs blinking
constantly as the `Hula-Hoop` rotates. The blinking connector is
endurable to long and repeated rotational motion of the
`Hula-Hoop`.

Description
[0001] This invention relates to an electrically blinking
`Hula-Hoop`.
BACKGROUND OF THE INVENTION
[0002] Many people think about an electrically blinking jump rope
for fun. But it is difficult to supply an electric power to the
light sources in a desired blinking pattern. Especially, there has
been difficulty in providing electric power to light sources
according to the motions of rotation of the Hoop. Therefore, most
of the prior arts decorate the appearance of the Hoop itself or
change the structure collapsible.
[0003] 1. Field of the Invention
[0004] This invention relates to an electrically blinking
`Hula-Hoop`, especially responds to the rotational motion of the
Hoop by utilizing two electrical blinking connectors.
[0005] 2. Description of the Prior Arts
[0006] U.S. Pat. No. 6,440,047 to Huang illustrates an exercising
device for simulating hula-hoop rotations includes: a housing
having at least a track annularly formed in the housing, at least a
ball rolling or rotatably moving in the track upon a hula-hoop
rotation by a user who wears the housing of the exercising device,
and an audio and visual device provided on the housing to indicate
or display the whirling movements audio visually.
[0007] U.S. Pat. No. 5,997,449 to Lee illustrates a hula-hoop
includes a body having a hollow portion at an inner side thereof,
and a plurality of rollers equidistantly spaced apart and pivotally
mounted in the hollow portion of the hula-hoop body. U.S. D

442,234, U.S. D 442,233 to Seo illustrate hula-hoop having a
plurality of hemi-sphere balls anchored to the inner side of the
hula-hoop to press the waist of a user. U.S. D 442,094 to Seo
illustrates a hula-hoop equipped with an electronic counter.
[0008] U.S. Pat. No. 5,895,309 to Spector illustrates a hula-hoop
including an inflatable annular core formed of plastic film or
other flexible material enclosed within an annular fabric casing to
provide a hoop of high strength which when not in use can be
collapsed and folded to assume a compact state for storage and
shipment. U.S. Pat. No. 5,569,134 to Nordanger introduces a
collapsible hula-hoop formed of a plurality of extruded plastic
tube sections which can be bent from a straight shape into an
actuate shape. None of the prior art introduces a blinking
hula-hoop according to the motion of the player's waist.
SUMMARY OF THE INVENTION
[0009] It is the purpose of this invention to provide a hula-hoop
electrically blinking along with the rotating motion of a user's
waist. The radius of the hula-hoop is in the range of 30 to 60 cm.
The diameter of the tubes is in the range of 2 to 3 cm. The
electrically blinking jump rope is comprised of; 1) eight pieces of
flexible tube of transparent material, 2) a blinking lightning
circuit comprised of one or two electric wire, plurality of LEDs
connected to the electric wires, and a blinking connector, 3) a
power switch on the circuit board, 4) two `AAA` size 1.5 Volt
batteries. Power supply is activated by turn on the switch on one
of the circuit. The blinking connector is a liquid metal/metal ball
connected light bulb having two sets of (+), (-) leads at the end
of the bulb. The liquid metal/metal ball oscillates in the bulb as
along with a motion of the user, such as turning the hoop. The bulb
blinking connector endures for the long and repeated rotational
motion of the hula-hoop.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0014] FIG. 1 shows a perspective view of the hula-hoop (1) of this
invention. The radius of the hula-hoop is in the range of 30 to 60
cm. The diameter of the tubes is in the range of 2 to 3 cm. The
electrically blinking hula-hoop (1) is comprised of eight pieces of
flexible tubes (2) of transparent material, eight pieces of tube
connectors (2-1), a lightning circuit (3) comprised of electric
wires (4), plurality of LEDs (5) connected to the electric wire, a
blinking connector (6), circuit board (7), batteries (8) for
electric power source, and a power switch (9) projected out on one
of the flexible tube (2) and connected to the circuit board (7),
for electric connections.
[0015] FIG. 2 is an electrical circuit (3) for blinking hula-hoop.
The circuit is comprised of; 1) one wire (4), 2) plurality of LEDs
(5) connected to the wire (4), a blinking connector (6), circuit
board (7) for electric connections, and two batteries (8) connected
in series. One end of the electric line (4) is connected to a (-)
electrode (10) of on/off switch (9) and the other end of the
electric line (4) is connected to a (+) electrode (11) the other
side of the circuit board (7). This (+) electrode (11) is connected
to the blinking connector (6). When the on/off switch (9) is
connected, i.e., "ON", an electrical circuit is established, i.e.,
electron comes out from the batteries (8) pass through the on/off
switch (10), flows through the electric wire (4), pass through the
LEDs (5) and reach to the (+) electrode (11) on the circuit board
(7).
[0016] FIG. 3 is a schematic drawing of the blinking connector (6)
of the current application. The electrons pass through the blinking
connector (6), if the liquid metal/metal ball (12) in the connector
(6) connects one set of the two metal wire leads (13) and (14),
which are connected to another two metal tape leads of (15) and
(16), respectively. The two metal tape leads (15) and (16) are
located on opposite side of the blinking connector (6) on the
circuit board. The electrons go into the (+) electrode of the
battery (8). Then the LEDs (5) are turned on. If the liquid
metal/metal ball is not in position of connecting the two metal
wire leads, (13) and (14) or (13') and (14'), facing each other on
opposite direction, the LEDs (5) will be turned off.
[0017] FIG. 4 is another embodiment of the current application. It
shows another electrical circuit (3-1) for blinking hula-hoop (1),
wherein the batteries (8') and LEDs (5) are connected in parallel
via two electric wires (4') and (4"). One of the metal tape lead
(15') is connected to the other (-) electrode (18) of the batteries
(8'). If the on/off switch (10') is connected "On", the electrons
come out the battery (8'), pass through the on/off switch (10'),
flow through the electric wire (4'), reach the conjunction point
(17). The electron can go on flow to the LEDs (5) and to the other
electric wire (4") as far as the blinking connector (6) is in
connection mode. In this connection mode, the liquid metal/metal
ball (12) connects the metal wire leads of (13) and (14) or (13')
and (14'). If the liquid meta/metal ball (12) does not connect the
metal wire leads, the circuit (3-1) is disconnected and the LEDs
are off.
[0018] The oscillation movement of a player will make the liquid
metal move between the wire leads of (13), (14) and (13'), (14').
This movement of the liquid metal/metal ball (12) makes the LED's
(5) blinks along with the movement of the player's waist
movement.
