Description
[0001] This invention is related to an electrically blinking jump
rope.
BACKGROUND OF THE INVENTION
[0002] In order to create a desired blinking pattern in the light
sources for a fun electric jump rope, many attempts have been made
to supply the electric power to these light sources. It has taken
great difficulty to provide electric power to the light sources in
compliance to the fluctuations of using a jump rope, from being
swung in the air to the impact of the ground. In addition, the
prior art devices have not satisfactorily solved the problem to
prevent the wind-up of the jump rope between the handles while it
continuously supplies electric power to the light sources.
[0003] 1. Field of the Invention
[0004] This invention relates to an electrically blinking jump
rope, which responds to the jumping motion of a user by utilizing
two electrical blinking connectors and two electrical rotating
connectors.
[0005] 2. Description of the Prior Arts
[0006] U.S. Pat. No. 5,087,034 to Solis illustrates a jump rope
which is made of a hollow, translucent, and flexible plastic tube
with a plurality of light sticks (CYALUME) inserted into the tube.
These light sticks glow when they are activated as the rope turns.
The light sticks may readily be removed and replaced when they are
expended. U.S. Pat. No. 5,389,056 to Ricker illustrates a jump rope
assembly with illuminated components comprised of a pair of
handles, where each handle has an inboard end and an outboard end.
One of the handles is hollow and contains electrical components,
such as a battery, electrical contacts and an on/off switch. U.S.
Pat. No. 4,776,585 to Maleyko, et al. illustrates an electrically
lighted jump rope with a flexible tube that transmits light through
each end of the rotationally mounted handles. U.S. Pat. No.
4,529,193 to Kuhnsman discloses a lighted jump rope, where a set of
optical fibers of varying lengths extends into the rope from each
of the handles. Energized by a battery, a switch arrangement
connected to a lamp in the handle lights each set of fibers. U.S.
Pat. No. 1,820,681 to Schmalbach discloses a jump rope, which is
provided with a plurality of spaced lamps that are placed
exteriorly on the rope and are then surrounded by balloons.
Batteries in the handles energize the lamps. The jump ropes do not
blink, but a continuous light emits from the lamps when turned on.
French Pat. No. 2,276,069 discloses an illuminated jump rope
comprised of a transparent or translucent tube with a pair of
handles rotationally mounted at opposite ends. The lighting circuit
includes a plurality of colored lamps disposed in the tube.
[0007] None of prior models disclose electrically blinking jump
ropes that automatically respond to the jumping motion of a user as
shown in 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) handles
rotationally connected to the flexible tube at each end, 3) two
rotational electrical connector, 4) a power switch on one of the
handles, 5) lightning circuit comprised of three electric wires,
plurality of LEDs connected to two of the three electric wires, and
a blinking connector. The rotational electric connectors enable a
constant power supply even at high-speed rotations and through
severe motions of the jump rope. The power supply is activated by a
turn of the switch on one of the handles. The blinking connector is
a liquid metal/metal ball connecting a light bulb that has two sets
of (+), (-) leads at the end of the bulb. The liquid metal/metal
ball oscillates in the bulb along with the motion of the user, such
as jumping. The rotational electric connector and the bulb blinking
connector are endurable for the long and repeated rotational
motions of the jump rope.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0014] FIG. 1 shows a perspective view of the jump rope model (1).
The electrically blinking jump rope (1) is comprised of: a flexible
tube that is made of partially transparent materials (2); handles
(3) containing batteries (4) for the electric power source that are
rotationally connected at each end; two rotational electrical
connectors (5); a power switch (6) on one of the rotational
electric connectors (5); lightning circuits comprised of three
electric wires (7, 8, 9) with a plurality of LEDs (10) connected to
two of the three electric wires; a blinking connection (11); and
circuit boards (12) for electric connections.
[0015] FIG. 1-1 is an enlarged view of the handle (3) of the jump
rope (1). The handle (2) has an empty space (13) for receiving
batteries (4). A spring (13) connects (-) the battery (4) to a thin
copper ribbon (5), which is extended to the upper end (14) of the
handle and forms a ring (15) along the edge of the upper end (14).
This (-) copper ribbon is connected to a (-) copper ring (16),
which is formed at the upper surface (17) of the handle cap (18).
(+) Electrodes (19) of the battery are directly connected to a bolt
(20) penetrating the center of the handle cap (18). This bolt is
engaged to a rotating nut (21) in FIG. 1-2. FIG. 1-2 is an enlarged
view of the rotating electric connector (5) of the jump rope (1).
The rotating electric connector is comprised of a lower part (22),
an upper part (23), and a pin (24). The pin (24) pivotally connects
the two parts through holes (25), (26), and (27) to connect the
arms onto the upper part (23). A pin (28) for connecting (-) is
inserted into a hole (29) developed trough the lower part (22) to
connect the (-) copper ring (16) and (-) copper arm (30) to the
upper part (23). The rotating nut (21) is connected to the (+)
copper terminal (31) inserted into the upper part (23). The (+)
copper arm and the (-) copper arms are connected to the (+)
connecting point (31) and the (-) connecting point (32),
respectively on the connection board (12) in the upper part (23) as
shown in FIG. 2.
[0016] FIG. 2 is an electrical circuit (33) for the blinking jump
rope. The circuit is comprised of: (1) three wires (7), (8), (9);
(2) plurality of LEDs (10) connecting two of the three electric
wires (7), (8), (9); a blinking connector (11); and circuit boards
(12) for electric connections. One line (7) is connected to a (+)
electrode with an on/off switch (34) and a (-) electrode (35) to
the other handle.
[0017] When the on/off switch is connected, i.e. turned "ON", an
electric circuit circulates from the (+) electrode of (31) the
switch (34), to the (-) electrode of (35) in order to pass through
the batteries (4) of FIG. 1-1, which are connected to the screw
electrode (20) of FIG. 1-1, which is then again connected to (+)
copper terminal (36). The electric blinking connectors (11), which
are connected to the electric line (9), pass through the LED (10),
connected to the other electric line (8) that is connected to a (-)
copper terminal (32), and then is established.
[0018] Once an electrical circuit is established, the blinking
connector (11) works as a temporary on/off switch. FIG. 3 is a
schematic drawing of the blinking connector (11) of this invention.
It is comprised of two sets each of two filament leads (37), which
is located at the opposite side of the small-vacuumed glass ball, a
liquid metal drop/metal ball (38) connects and disconnects the two
filament leads (37) by the motion of a jump rope user. The liquid
metal drop/metal ball (38) and the two filament leads (37) are
embedded in a small-vacuumed glass ball (39). When the liquid metal
drop/metal ball (38) is apart from both sets of the filament leads
(37), the electrical circuit is established above the disconnection
and the LEDs (10) will turn off. When the liquid metal drop (38) is
contacted with any set of the filament leads (37), the LEDs will
then turn on. The motion of the jump rope user (1) will let the
liquid metal drop/metal ball (38) oscillate in the vacuumed glass
ball (39) and let the LEDs blink. In FIG. 2, the leads (37) of the
electric blinking connector (11) are serially connected to the
diodes (40). This serial connection renders more frequent blinking
of LEDs (10).
