[0003]

However, among the above-mentioned grips, in the structure in which the cap is screwed to the grip and the rope body is rotatably locked to the cap, the rope skipping is performed. There was a problem that the cap rotates due to the influence of the rotation of the rope body side while the rope body is rotating, which causes the cap to loosen or come off from the grip. Therefore, in view of the above situation, the present invention has an object to prevent the cap from rotating in the detaching direction with respect to the grip head, even if it is affected by the rotation of the rope body, with respect to the structure for attaching the cap to the grip, The purpose is to prevent the cap from loosening or coming off.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above problems, and a grip for a rope for rope skipping is provided with a cap on the head side of the grip for rotatably locking the rope body. In the structure, the cap includes a threaded cylinder screwed to the head of the grip, and a rotary crown having a through hole for rotatably locking the rope body, and the rotary crown is rotated on the threaded cylinder. (EN) Provided is a grip structure for a rope for skipping rope, which is capable of being engaged and fixed, thereby solving the above-mentioned problems.

[0005]

In the present invention, the cap is separated into the screw-on cylinder on the grip head side and the rotary crown on which the rope main body is locked, and the rotation of the rope main body acts on the rotary crown to rotate it. Also, since the threaded cylinder and the rotary crown are rotatably connected, the rotation of the rotary crown is prevented from being transmitted to the threaded cylinder. For example, in the conventional structure, the rotation of the rope body causes 10
When a rotational force of Kg is applied, the grip itself is held and fixed by a person. Therefore, if the rotational force acts on the cap in the removing direction, the cap rotates in the removing direction. Like However, in the structure of the present invention, even if a rotational force of 10 kg is applied to the cap side (2 parts) due to the rotation of the rope body, the rotational force directly acts on the rotary crown. The rotating crown does not rotate and the rotational force is not transmitted to the threaded cylinder side.
