Description

Adjustable cord length skipping 【0001】

This creation is directed to providing a skipping cord that can adjust the length of the cord, which refers to a skipping rope configuration that is capable of adjusting the length of the cord.

【0002】

Skipping rope is a common and widely used sporting goods. Its structure is usually two grips and one rope body. The two ends of the rope body are respectively fixed on the two grips, so that the athlete can make a jumping sport type. When the athlete uses the skipping rope and is used up, the skipping rope must be stored for the next use. However, usually the rope body is designed to be long enough for people of all sizes, so the rope skipping rope will be irregular when stored. The shape of the curl and occupy a large space, making the storage of the skipping rope extremely inconvenient, and also visually feels quite messy, and it is easy to trip over the passing person; the traditional skipping rope mainly connects the ends of the rope body to the grip. And the front end of the grip is fixed to the rope body for the user to hold the grip and use the skipping rope. The length of the traditional skipping rope is fixed and the length of the used rope cannot be adjusted, so the petite person is not caught by the rope body in the skipping rope. The cord is usually wrapped around the wrist to shorten the length of the skipping rope. After the skipping rope is wound, the cord is easily curled, and the wrist is also easily injured.

[0003]

Refer to the Republic of China Patent Bulletin M465944 "Jumping rope with wire rope retracting device". This patent mainly solves the following problems: the conventional skipping rope, the rope system is fixed to the two grips, the length cannot be adjusted, and the user needs to be used for the user. The height or the type of activity to be performed is suitable for the length of the rope, so the same skipping rope is not necessarily suitable for users of various heights or different types of rope skipping activities. Moreover, due to the rope skipping, the rope body is constantly rotating and rotating. The process will be distorted, and how to store the rope is also a big problem.

[0004]

In order to solve the above problem, the patent mainly constructs a skipping rope with a cord retracting device, comprising: a holding body having a receiving groove therein and a rope hole and an adjusting hole on both sides, the rope The hole and the adjusting hole are connected to the receiving groove; an adjusting rod group, one end of which is disposed through the adjusting hole on one wall of the receiving groove, and the other end is exposed outside the holding body; and a rope body passing through The rope hole is connected to the adjustment rod group.

[0005]

Although the above patent is also for solving the problem that the conventional skipping rope cannot adjust the length, the main structure is that the adjusting rod body is rotated by externally rotating the adjusting rod body to roll the rope body, and the rope body is to be wound. When fully retracted, the adjustment rod body must be continuously rotated, which not only consumes physical strength, but also takes unnecessary time. In addition, after the rotation of the rope body is positioned by the adjustment rod group, if the rope body is subjected to a large external force, The rope body will also drive the adjustment rod body to rotate, so it is necessary to improve.
