Abstract

A rope skipping handle capable of adjusting a rope length is disclosed, in which the length of a rope can be easily adjusted within a certain length range so that both children and adults can easily use the same. The rope is wound or unwound from a rotary shaft of a handle by operating a rotary shaft handle installed at an end of a rope skipping handle, so that the length of a rope can be easily adjusted. It is possible to easily adjust the length of a rope based on a user physical condition. With larger length adjusting ranges, both children and adults can easily use the skipping rope irrespective of the heights of the users. The adjusted rope is hidden in the handle, so that the outer look is good. It is easy to use.

Description

ROPE SKIPPING HANDLE WHICH IS USEFUL FOR REGULATION ROPE LENGTH

Technical Field The present invention relates to a rope skipping handle capable of

adjusting a rope length, and in particular to a rope skipping handle capable of

adjusting a rope length in which a rope length of a rope skipping apparatus can

be easily adjusted by winding or unwinding a rope from a rotary shaft installed in

a handle based in an operation of a rotary shaft handle installed at each end of

a rope skipping handle.

Background Art

In a conventional apparatus for adjusting a rope length, a rope is folded

at a ring connection part of a handle, and two ropes are inserted into the holes

of an. engaging part in parallel, and two ropes are folded at a rope skipping

apparatus. In another method, a rope length is adjusted using an edging

principle in a rope skipping handle.

In the later case, a rope is extended from a rear hole of a handle for

thereby adjusting the length of a rope for thereby causing many inconveniences.

A coupled state of a rope engaging part may be loosened by repeated vibrations, so that the rope may be automatically unwound. In particular, there is a problem that it is impossible to adjust the length of a rope beyond a rope

skipping rope within its rope length adjusting range. Therefore, there are many

problems in using by both children and adults.

Disclosure of Invention

Accordingly, it is an object of the present invention to overcome the

above-described problems encountered in the conventional art.

It is another object of the present invention to provide a rope skipping

handle capable of adjusting a rope length in which the length of a rope can be

easily adjusted within a certain length range so that both children and adults

can easily use the same.

To achieve the above objects, a rope 22 is wound or unwound from a

rotary shaft 13 of a handle 10 by operating a rotary shaft handle 11 installed at

an end of a rope skipping handle 10, so that the length of a rope can be easily

adjusted. It is possible to easily adjust the length of a rope based on a user physical condition. With larger length adjusting ranges, both children and adults can easily use the skipping rope irrespective of the heights of the users. The adjusted rope 22 is hidden in the handle 10, so that the outer look is good. It is easy to use. A light and flexible rubber ball 21 is inserted into the skipping rope 22, so that the user can skip beyond the height of the ball 22 when exercising using the rope of the present invention for thereby enhancing exercising effects. The spring 20 is inserted at both ends of the rope, so that the tope 22 maintains an

elastic force for thereby preventing the rope 22 from being tangled or twisted.

With the above features, in the present invention, it is possible to freely

adjust the length of a rope. Exercising effects may be maximized using a rope

twisting and tangling function and a flexible rubber ball.

Brief Description of Drawings

The present invention will become better understood with reference to

the accompanying drawings which are given only by way of illustration and thus

are not limitative of the present invention, wherein;

Figure 1 is a perspective view illustrating a rope skipping handle capable

of adjusting a rope length according to the present invention; and

Figure 2 is a cross sectional view of a structure of the present invention.

Best Mode for Carrying Out the Invention

Figure 1 is a perspective view illustrating a state that a rope skipping handle according to the present invention is engaged to a skipping rope; and Figure 2 is a cross sectional view illustrating a state that a pair of rope skipping handles are engaged to a skipping rope according to the present invention. The preferred embodiments of the present invention will be described with reference to the accompanying drawings.

In the present invention, there are provided a pair of handles 10, a rotary shaft 13 engaged with a rotary shaft handle 11 , a conical part engaging

step 11 for preventing an escape of the rotary shaft, and a connection rope 22

for integrally connecting a flexible rubber ball 21 together with a spring 20 at a

lower side of the handle 10 engaged with a rope fixing hole 12 that fixes the

rope at the rotary shaft.

The operation of the present invention will be described. First, when a user wants to decrease the length of a rope based on his

physical condition, the user holes the handle 10 with one handle and rotates the

rotary shaft handle 11 with the other hand in the right direction, so that the rope

22 is wound onto the rotary shaft 13 for thereby decreasing the length of the

rope. On the contrary, when the user wants to extend the length of the rope, the

user rotates the rotary shaft handle 11 in the left direction, so that the rope 22 is

unwound from the rotary shaft 13 for thereby increasing the length of the rope.

Therefore, the user can use the skipping rope based on his physical condition.

The rope 22 unwound from the rotary shaft 13 is naturally extended to the

outside of the rope skipping handle 10 based on an elastic force of the spring 20 engaged to the rope 22. In addition, the rope 22 is not twisted or does not get tangled when plating the skipping rope. The rope 22 can always maintain an adjusted state.

Industrial Applicability

As described above, in the present invention, since the rope 22 is wound or unwound from the rotary shaft 13 of the handle 10, so that both children and

adults can easily use the skipping rope irrespective of their heights with large

length adjusting ranges. Since the wound rope 22 is wound in the interior of the

handle 10, the outer look is good, and it is easy to use. In particular, the skipping height may be increased based on the

diameter of the flexible rubber ball 21. Weight is generated based on the

centrifugal force. Exercising effect is increased as compared to the conventional

rope skipping, so that it is possible to achieve a desired diet effect for shorter

time period. As the present invention may be embodied in several forms without

departing from the spirit or essential characteristics thereof, it should also be

understood that the above-described examples are not limited by any of the

details of the foregoing description, unless otherwise specified, but rather

should be construed broadly within its spirit and scope as defined in the

appended claims, and therefore all changes and modifications that fall within

the meets and bounds of the claims, or equivalences of such meets and bounds

are therefore intended to be embraced by the appended claims.

Claims

Claims:

1. A rope skipping handle structure capable of adjusting a rope length,

comprising: a rotary shaft handle 11 provided at a pair of handles 10 for adjusting
