Problems solved by technology

[0003]The various rotating swings and swings made by the public using the rotating swing principle, such as adult rocking chairs, baby cradles or cradles, children's rocking horses, etc. It can only swing in a single direction front and back, and the entertainment and interest embodied in the actual use of the existing rotary swing are not sufficient or perfect

[0004] Although the "Tumbler Fitness Rocking Chair" with the application number 200720157550.X provides the public with a rocking chair technology that can rock in multiple directions, this technology is easy to exist The defects are as follows: 1. The technical solution of the rocking chair requires a large counterweight, which makes the rocking chair relatively heavy, not only consumes a lot of materials, but also has high production costs, and is also not conducive to the movement and circulation of the rocking chair product

2. In this technical solution, because "the chair is located in the tumbler shell", it is not easy for people to sit directly on the "chair", or it is not easy for people who have been sitting on the "chair" to get off the rocking chair, that is, people are in the rocking chair. Sitting up and sitting up is inconvenient, making the rocking chair only "especially suitable for use by children"

Even if the rocking chair is used by children, the help of adults around the rocking chair is required, such as picking up the child on the "chair" or taking the child away from the "chair", that is, the child is not suitable or unable to move from the "chair" The rocking chair can go up and down by itself, otherwise, the rocking chair will be unbalanced and the child will fall and be injured. The use of the rocking chair is likely to have potential safety hazards

"The chair is located in the tumbler shell", which makes it more inconvenient for adults to sit up or sit down on the rocking chair, and is more likely to cause safety problems

3. This technical solution makes it difficult for the feet of the person sitting on the "chair" to contact the support surface of the rocking chair because "the chair is located in the tumbler shell", so that the person sitting on the rocking chair cannot drive the rocking chair by himself. The rocking chair rocks back and forth, meaning that the person sitting in the rocking chair needs help from those around the rocking chair to achieve the rocking

4. In order to keep the rocking chair from falling down, the rocking chair must be bulky as a whole, so that it is laborious to drive and the swing efficiency is low. It needs continuous external force support to maintain the swing, so that the swing of the rocking chair is mostly in a passive driving swing state, and the rocking chair It is difficult to obtain free reciprocating swing and lack the effect of leisure use in the free swing state, and it is difficult to meet the requirements of leisure use; and because the rocking chair is bulky as a whole, it is easy to generate a large impact on the ground or floor and easily cause vibration and noise. It is not conducive to the popularization and application of this technical solution

5. When an adult with a large mass uses the rocking chair, the overall center of gravity of the rocking chair and the human body tends to move upwards, which easily affects the normal or safe use of the rocking chair. Although the rocking chair is equipped with a safety belt, However, it is impossible to completely eliminate the potential safety hazards in its use.

6. When the rocking chair is rocking, it is not only easy to damage the supporting floor or ground where it is located, but also the overall position of the rocking chair is easily shifted and deflected, that is, the rocking chair cannot always keep swinging at the original supporting position, making it It is inconvenient to use it in a limited space and needs to be moved and corrected frequently
