Length-adjustable all-weather jumping rope device
Abstract
This invention of a jumping rope device is comprised of Wire
Rope the core of which is made of twisted wire strands being
covered with plastic whereby the Wire Rope, as normal jump rope, is
linked with the handles respectively at the end of the Wire Rope;
both handles are identical each other in its structure wherein the
main body is of a elongated cylinder at one end of which is
externally threaded thus to receive internally threaded cap having
a central hole which is inwardly protruded with an annular wall to
function as bearing in connection with the Wire Rope holder by
means of screw bolt to adjust the length of the Wire Rope by height
of the jump rope user; the Wire Rope can be used for rope jumping
exercise in a worst weather such as with strong wind over 30 miles
per hour.

Claims
I claim:
1. The Length Adjustable All Weather Jumping Rope Device is
comprised of Wire Rope the core of which is fabricated with cables
of twisted wire strands and externally covered with plastic,
2. The Jumping Rope Device includes a pair of Handles which are
identical each other; having an elongated cylinder and cap, and the
elongated cylinder being with one end closed and the other end
flanged with threads to have Cap fixed thereon, and Cap has a hole
at the hemispherical center that is inwardly protruded to form Hoop
for slide bearing function along with the outer annular wall of the
Wire Rope Holder device;
3. The Wire Rope Holder is of a metal Hoop with one side that is
penetrated with a hole accommodating screw bolt thereon which, when
tightened, is to hold the Wire Rope; as such the length of the Wire
Rope can be adjustable with use of the Wire Rope Holder for an
individual user's height.
Description
BACKGROUND OF THE INVENTION
[0001] The inventor of the present invention has a long history in
his personal life in connection with Jump Rope which he started
from Jan. 1, 1960, from the starting point in 1,000 revolutions of
rope jumping every morning, with almost no skipping days ever
since, while renewed challenge with unvacillating intrepidity,
because the rope jumping exercise which takes less than ten minutes
has brought about tremendous advocate in his health maintenance,
year in year out, particularly related with active heart pulsation
and positive supply of fresh air soaked blood to brain through the
regular exercise early in the morning, and in the meantime he has
changed all kinds of jump ropes while evaluating which was the
best. Through his experiences of rope jumping history, what he was
frustrated most was windy days when he was unable to do rope
jumping in the wind that devastating the challenging rhythm of rope
jumping, and consequently he found the best one using the jumping
code with the Wire Rope which is made of cable of twisted wire
strands that is covered with thermoplastic, such that there is no
problem even before a strong wind of over 30 miles per hour. The
present inventor has been using the new jump rope material since
five years ago, while distributing the new ones more than 50 sets
to his friends who urged him to apply a U.S. patent. In this
regard, the present inventor has closely referred the following
U.S. patents:

SUMMARY OF THE INVENTION
[0002] The present invention of jumping rope apparatus is comprised
of a sufficient length of Wire Rope and a pair of thermosetting
plastic handles, which are identical each other in structure; the
Wire Rope is made of several cables each of which is of twisted
wire strands, and the cable core of the Wire Rope is coated with
plastic cover that is tightly immersed throughout the surface of
the cable core, and therefore in quality aspect the Wire Rope is of
high density yet with perfect flexibility, such that the Wire Rope
is longitudinally bent to extreme degree, though, it returns to
straight when it is released from bending. In the weight aspect, a
set of Wire Rope with measurement of 105 inches in length and
{fraction (3/32)} inch diameter weighs same as that of conventional
jump rope that is measured 105 inches long and 1/4 inch in
diameter. The handle made of thermosetting plastic is consisted of
two parts--one in an elongated cylinder with one open end having
flange and external threads thereon and another one as cap with
internal threads and having a hole at the hemispherical center
which is internally protruded with peripheral surface for the
function of sliding bearing in connection with the lower part of
the Code Holder having a screw bolt that is manipulated by means of
screw driver in order to adjust the length of the Jumping Rope
suited to a user's height for which the cylindrical space of the
elongated handle is enough retaining about five inches of the end
portion of the jumping rope whereby to adjust correct length of the
rope suitable to user's height. When the length of the Wire Rope is
correctly fixed by adjusting and tightening the screw bolt of the
Wire Rope Holder through which the jumping rope is passed and
safely held by the screw bolt thereof whereby the outer surface of
the Wire Rope Holder is sliding in touch with the peripheral hoop
of the internally protruded hole of the cap as such that when in
operation, both ends of the Wire Rope held within the cylindrical
spaces of the handles are just smoothly slipping with the
revolutions of the jumping rope. In this context, the peripheral
hoop of the thermosetting plastic cap is safe to resist to the
friction caused with the outer surface of the Wire Rope Holder
because the quality of the thermosetting plastic is safe enough up
to 500 degrees in Fahrenheit. As stated above, the present
invention is very simple to assemble and even with one set of Jump
Rope everyone of a family can enjoy by readjusting the length of
the jump rope by means of manipulating the screw bolts contained in
the handles with use of a screw driver, and in addition once it is
on marketing, the price may be the lowest compared with the
conventional jumping ropes in the market.
BRIEF DESCRIPTION OF THE DRAWINGS
[0003] FIG. 1 is longitudinally depicting cross sectional view of
the handle, such as Elongated Cylinder (1) containing the end part
of Wire Rope (3) which is passed through the handle Cap (2) fixed
to the Elongated Cylinder (1) by means of threads, and the Wire
Rope in the meantime is firmly held by the Wire Rope Holder
(4).
[0004] FIG. 2 depicts the exploded view of the Wire Rope with Core
(3-a) of the twisted cables and Plastic Cover (3-b). FIG.3 shows
Wire Rope Holder (4) which is adjustably holding Wire Rope by means
of Screw Bolt (4-a) with threads (4-b) thereon.
[0005] FIG. 4 is the perspective broken view of the Cap (2) showing
the inwardly protruded Hoop (2-a).
[0006] The FIG. 5 shows the jumping rope which is adjusted to the
maximum length, and
[0007] FIG. 6 is the shortened length of the Wire Rope for rope
jumping.
DESCRIPTION OF PREFERRED EMBODIMENT
[0008] The present invention of the Length Adjustable All Weather
Jumping Rope Device is closely related with the personal life of
the inventor whose daily motto is first to have rope jumping one
thousand revolutions every morning which nowadays need less than
400 seconds since Jan. 1, 1960, and ever since he has realized with
the remarkable health improvement and spiritual positiveness which
he regards most important of all in human daily life.
[0009] The jumping rope of the present invention is very easy to
assemble such as the plastic Handles, identical each other,
respectively have a internally threaded Cap (2) which is to be
fixed to Elongated Cylinder (1) the open end of which is also
threaded with annular flange right above the Cap (2) fringe.
[0010] For assembly, each end of the Wire Rope is put through the
inwardly protruded Hoop (2-a) and then pass the hole of the Wire
Rope Holder (4) whereupon the Wire Rope (3) is tightened with the
Screw Bolt (4-a) after adjustment of the length of the Wire Rope to
meet the height of a user. Since the Wire Rope is of the twisted
cable core covered with plastic, its quality is very stiff yet
significantly flexible for operation of rope jumping exercise, so
that there is no disturbance with a longer end of the Wire Rope
that extended inside the Handle Cylinder for the length
adjustment.
