Motion responding electrically blinking jump rope (II)
Abstract
An electrically blinking jump rope is comprised of; 1) a
flexible tube of partially transparent material, 2) two handles,
containing batteries for electric power source, connected to the
flexible wrinkled tube at each end, 3) a power switch on one of the
handles, 5) a blinking lightning circuit comprised of two electric
wires, plurality of LEDs connected to the two electric wires, and a
blinking connector. The flexible wrinkled tube connecting the
handle and tube of the rope enables a steady power supply even at
high-speed rotation and severe motion of the jump rope. Two
blinking connector is endurable to long and repeated rotational
motion of the jump rope.

Description
BACKGROUND OF THE INVENTION
[0001] Many attempts to provide an electrically blinking jump rope
for fun has been difficulty in supplying 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 swinging and impact of the jump rope to
the ground. In addition, the prior art devices have not
satisfactorily solved the problem of preventing wind-up of the jump
rope between the handles while continuously supplying electric
power from a handle to light sources in the rope.
[0002] 1. Field of the Invention
[0003] This invention relates to an electrically blinking jump
rope, especially responds to the jumping motion of a user by
utilizing two electrical blinking connectors and two flexible
wrinkled tubes.
[0004] 2. Description of the Prior Arts
[0005] U.S. Pat. No. 5,087,034 to Solis illustrates a jump rope
which is made of a hollow translucent, flexible plastic tube and a
plurality of light sticks (CYALUME) inserted in the tube which
glows when the light sticks are activated as the rope turns. The
light sticks may be readily removed and replaced when they are
expended. U.S. Pat. No. 5,389,056 to Ricker illustrates a jump rope
assembly with illuminated components comprising, a pair of handles,
each handle having an inboard end and an outboard end, one of the
handles being hollow and having therein electrical components
including a battery, electrical contacts and an on/off switch. U.S.
Pat. No. 4,776,585 to Maleyko, et al. to illustrates an
electrically lighted jump rope with a flexible tube of light
transmitting material and handles rotationally mounted thereon at
each end. U.S. Pat. No. 4,529,193 to Kuhnsman discloses a lighted
jump rope wherein a set of optical fibers of varying length extends
into the rope from each of the handles. A lamp in the handle, which
is energized from a battery, and switch arrangement in the handle
light each set of fibers at the handle. U.S. Pat. No. 1,820,681 to
Schmalbach discloses a jump rope, which is provided with a
plurality of spaced lamps which are disposed exteriorly of the rope
and which are surrounded by balloons. Batteries in the handles
energize the lamps. The jump ropes do not blink but turn on and off
a light.
[0006] French Pat. No. 2,276,069 discloses an illuminated jump rope
comprising a transparent or translucent tube with a pair of handles
rotationally mounted at opposite ends. A lighting circuit includes
a plurality of colored lamps disposed in the tube.
[0007] None of prior arts disclose electrically blinking jump rope,
which responses to jumping motion of a user shown as this
invention.
SUMMARY OF THE INVENTION
[0008] It is the purpose of this invention to provide a jump rope
electrically blinking along with the rotation and jumping motion of
a user. The electrically blinking jump rope is comprised of; 1) a
flexible tube of partially transparent material, 2) two handles,
containing batteries for electric power source, connected to the
flexible wrinkled tube at each end, 3) a power switch on one of the
handles, 5) a blinking lightning circuit comprised of two electric
wires, plurality of LEDs connected to the two electric wires, and a
blinking connector. The flexible wrinkled connector enables a
steady power supply even at high-speed rotation and severe motion
of the jump rope. Power supplies is activated by turn on the switch
on one of the handle. 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 in the
bulb oscillates along with a motion of the user, such as jumping.
The rotational electric connector and bulb blinking connector
endures for the long and repeated rotational motion of the jump
rope.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0013] FIG. 1 shows a perspective view of the jump rope (1) of this
invention. The electrically blinking jump rope (1) is comprised of
a flexible tube of transparent material (2), handles (3) containing
batteries (4) for electric power source and two flexible wrinkled
tube connector (5) with plastic head (6), a power switch (7) in one
of the plastic head (6), lightning circuit comprised of two
electric wires (8), (9), plurality of LEDs (10) connected to the
two electric wires in parallel, a blinking connector (11) on a
circuit board (12) for electric connections in the same handle
(3).
[0014] FIG. 2 is an exploded view of the handle (3) of the jump
rope (1) and the flexible wrinkled connector (13) with a solid
plastic head (6). The handle (3) has void (15) for receiving
batteries (4). A spring (16) contacting (-) of the battery (4) is
connected to a thin copper ribbon (17). The copper ribbon (17) is
extended to the upper end of the handle and connected with the
electric wire of (8). The (+) electrode of the battery (4) on upper
side of the handle (3) is connected to another electric wire (9)
after meet the blinking connector (11) on a circuit board (12),
which is inserted in the plastic head (6) of the flexible wrinkled
connector (13). The ends of the electric wire (9) is extended down
to the inner surface of the handle cover (19) after pass through
the blinking connector (11) to meet the (+) electrode. The end of
the electric wire (8), after pass the metal plate (18) of the
on/off switch (7), is connected to a the copper ribbon (17)
extended from the (-) electrode of the battery (4). One end of the
flexible wrinkled connector (13) is connected to the solid plastic
handle cover (19) and the other end is connected to a solid plastic
head (6). The flexible transparent tube (2) is inserted to the
plastic head (6) and the end (20) of the tube (2) is enlarged by
heat treatment to form a knot. The electric wires (8) and (9) are
inserted to the plastic head (6) and connected to the LEDs and the
blinking connector (11).
[0015] FIG. 3 is an electrical circuit for blinking jump rope of
the current application. Pluralities of LEDs (10) are connected to
the electric wires (8) and (9) in parallel. One end of this
electric circuit is connected to the (+) and the (-) electrodes of
the batteries (4). The on/off switch (7) is provided for main power
connection. When a user turn on the on/off switch (7), the
electrons from the (-) electrode of the batteries (4) flow through
the on/off switch (7) and reach the junction point (21). The
electrons flow into both of the two direction (21-a) and (21-b) if
the liquid metal/metal ball (22) connects a pair of lead wires
(23), (23') and (24), (24'). Then the LEDs (10) are on. If the
liquid metal/metal ball (22) does not connect a pair of the lead
wires, the LEDs are off.
[0016] FIG. 4 is a schematic drawing of the blinking connector (11)
of the current application. It is comprised of two set of two pairs
of filament leads (23), (23') and (24), (24'), which locate at the
opposite side of the small-vacuumed glass ball, a liquid metal
drop/metal ball (22) connects and disconnects the two pairs of
filament leads, connect (23) and (23') or (24) and (24'), along
with the motion of a jump rope user. The liquid metal drop/metal
ball (22) and the filament leads (23), (23'), (24), and (24') are
embedded in a small-vacuumed glass ball (25). When the liquid metal
drop/metal ball (22) is apart from both of the filament leads' set,
the electrical circuit established above is disconnected and the
LEDs (10) will turn off. When the liquid metal drop (22) is
contacted with any pair of the filament leads' set, the LEDs will
turn on. The motion of a user of the jump rope (1) will let the
liquid metal drop/metal ball (22) oscillate in the vacuumed glass
ball (25) and let the LEDs blink.
