Description

A flat type automatic folding combined table and chair

technical field

The invention relates to a flat plate type automatic folding combination table and chair hidden on the ground, especially a flat type automatic folding combination table and chair which can be automatically lifted by a controller.

Background technique

In modern society, with the development of the economy, more and more people are pouring into the city, which makes the use of urban space resources more and more tense. How to fully improve the utilization of space has become an urgent problem to be solved. Although traditional tables and chairs emphasize structure It is solid and beautiful in shape, but such a structure will inevitably occupy a large space. Under such circumstances, a variety of utensils with ingenious structural design and applied indoors appear in large quantities. Under this background, multi-functional folding combination tables and chairs emerged as the times require.

Although traditional folding tables and folding chairs have achieved full use of space to a certain extent, they still take up a lot of space. At the same time, when traditional folding tables and chairs are used, people usually apply external force and use the special structural design of folding tables and chairs to fold them up. When not in use, people also manually fold them up to save space. However, this kind of folding table and chair usually needs people to use both hands and use a lot of strength to complete it, which is not only inconvenient to operate but also prone to pinching people's palms, so there is a certain potential safety hazard.
