Description

medicine ball structure

The present invention relates to a fitness ball structure, especially a fitness ball that uses centrifugal rotation to achieve fitness effects, and can transmit fitness and other related information data to an external portable electronic device from a bluetooth transmission device.

First of all, as shown in the new patent certificate number M611203 of the Republic of China, it is the structure of the rotating body previously applied by the inventor, wherein, the rotating system is provided with a spindle inside a rotating body, and two ends of the spindle are respectively pivoted. Bearings, and the center of the mandrel extends vertically with a rotating part, which rotates radially and centrifugally with the mandrel as the axis, and the rotating part can be further provided with at least one counterweight, and the rotating part The length of the combined counterweight is smaller than the radius of the rotating body; with the above structure, the user can operate the rotating body at any time, and perform hand, wrist, or foot training, and when applying force to the rotating body When the body is rotated, the rotating member, or even combined with the counterweight, will rotate silently inside the rotating body. However, there are the following disadvantages:

(1) Each of the single bearings is embedded in the corresponding single slot, and the design structure of the slot is too weak. Therefore, when the rotating body is shaken for a period of time, the slot will break or break.

(2) The rotating system is composed of two shells. The structure at the periphery of the two shells is not rigid enough, and some soft deformation will occur. Especially when the rotating body is not dropped, the rotating body is easy to Break from the periphery where the two shells join.

(3) When a force is applied to the rotating body, the rotating member or even the combined counterweight will rotate silently inside the rotating body. Therefore, the user is allowed to repeat the swinging action all the time, and does not know The length of time used, the energy consumed by the body and other values are boring.

In view of this, the inventor has been engaged in the manufacture, development and design of related products for many years. After careful design and careful evaluation for the above-mentioned goals, he finally obtained a practical invention.
