Abstract

A rope control device of the jumping rope sporting device is provided, which enables a user to arbitrarily control the length of the jumping rope sporting device. A rope control device of the jumping rope sporting device is constituted as follows. A rope(7) is mounted on a handle(1) by using an elasticity screw part(5) and a joint nut(6). A groove(4) formed in the one-side end peripheral part of a male screw pipe(3) is rotatably inserted into a hole(2') bored on the cap(2) of the handle. A screw part of the male screw pipe is expansible by a cutout. A screw nut is formed of the inner slope(6').

Description

Rope regulation skipping

1 is a perspective view of a portion of the present invention cut away.

2 is a side view of a portion of a conventional skipping rope.

3 is an exploded perspective view of the device of the present invention.

The present invention relates to a jump rope exercise device, and more particularly, to a configuration improvement of a rope length device that can arbitrarily adjust the rope length of a jump rope exercise tool.

Conventional rope skipping can adjust the length of the rope is attached to the connecting ring 22 to the fastener 21 is coupled to the handle 20, as shown in Figure 2, the end of the rope 23 is fitted Using the metal ring 24 and the adjusting ring 26, it is possible to adjust the length of the rope 23 of the rope skipping exercise tool as if it is to adjust the support strap of the prop, which is complicated to adjust the length of the rope 23. In particular, the part where the end of the string 23 is folded is doubled in thickness, and consequently, the thickness is not uniform with respect to the length of the string 23 between the two handles 20, so that the weight balance is not good. Not only is it difficult to use when skipping ropes, but there are disadvantages in that the folded part rotates up to the back of the user's hand.

As shown in Figs. 1 and 3, the constitution of the present invention includes a groove 2 formed in the periphery of one end of the male pipe body 3 arbitrarily rotating in the hole 2 'bored in the cap 2 of the handle 1. The fastening nut 6 is screwed into the flexible threaded portion 5 formed in the other side of the male threaded tube 4, but is screwed into the central through hole 1 ′ of the handle 1 through the male threaded tube 3. The end of the string (7) is fitted to be fixed.

Reference numeral 8 denotes a space 6 'between the leading end face of the handle 1 and the inner surface of the cap 2, the inner inclined portion 3' of the nut 6, the male threaded body 3 and the hole of the cap 2 ( A fixing screw for fluidly fixing to 2 ').

The threaded portion 5 of the male threaded pipe body 3 of the present invention has a cutout portion 5 ', which is stretchable, and the nut 6, which is screwed thereto, is formed with an inner inclined portion 6', so that the nut 6 Tighten), and the threaded portion (5) of the male threaded tube (3) is compressed to tighten the string (7) and loosen the nut (6) loosen the threaded portion (5) of the male threaded tube (3) to loosen the string (7).

That is, the end portion of the string 7 which is inserted into the central through hole 1 ′ of the handle 1 through the male threaded pipe 3 is tightly snapped onto the threaded portion 5 of the male threaded pipe 3 by tightening the nut 6. The line 7 will not fall out.

When adjusting the length of this line (7) according to the user's height, loosen the nut (6) and loosen the line (7) that was tightly held by the threaded part (5). (7) The length can be adjusted. When the length of the string is properly adjusted, tighten the nut 6 again. Such a jump rope exercise device of the present invention, the male screw pipe (3) is violently shaken when jumping rope, the groove portion (4) formed at one end of the male screw pipe (3) can be arbitrarily rotated in the hole (2 ') of the cap (2) In addition, the fixing screw 3 'fitted to one end of the male threaded tube 3 is located in a relatively large space 6' formed between the tip of the handle 1 and the inner surface of the cap 2, There is no fear of twisting the line (7) when rope skipping.

The central through hole 1 ′ of the handle 1 into which the end of the string 7 is inserted here is wide enough to allow the end of the string 7 to flow.

The jump rope exercise device of the present invention is extremely simple in the configuration of the connection portion is not only easy to operate, but also does not need to adjust the length of the rope by folding the line as in the prior art, the feeling of use and good at the same time do not hurt the hand.

Claims

In the rope length adjusting device of the skipping rope, in which the rope 7 is attached to the handle 1 with the elastic screw part 5 and the tightening nut 6, a hole 2 'is drilled in the cap 2 of the handle 1; There is a groove length adjustment device of the rope skipping movement groove is formed in the groove portion (4) formed on the circumferential surface of the one end end of the male pipe body (3) arbitrarily rotatable.
