Description

Base for bed, chair or sofa

This creation is related to furniture, especially a base for a bed, chair or sofa that provides the ability to sway or/and rotate in different directions.

Generally, the swingable bed or chair can only be swayed back and forth or left and right. Some types of chairs have a rotating function, but whether it is a one-way front or rear swing or a simple rotation, long-term use is easy. The user feels boring and can't achieve better relaxation. However, if you want to further develop a bed, chair or sofa that can swing and rotate at the same time, it will face many technical challenges. For example, many functions mean complicated structure and many components, which will lead to the volume of the base. The increase, especially the height, is likely to exceed the normal height of the general bed and chair, and the weight of the base will also increase, which is not conducive to transportation, and the manufacturing cost will also increase, which is unfavorable for market sales, and when the driving devices in all directions operate simultaneously, The noise generated by it is superimposed, and the user can't really relax.

One of the aims of the present invention is to provide a base for a bed, a chair or a sofa, which can provide the functions of swinging back and forth, swinging left and right, and rotating at the same time or separately, and the overall height is small, and the bed, chair or sofa is still installed after the base is installed. Meets the general use height.
