Description

Foldable table and chair dual-purpose device for pressing and fixing the buttocks

technical field

The invention relates to a foldable dual-purpose device for tables and chairs, in particular to a foldable dual-purpose device for tables and chairs which can be folded by pressing and fixing the buttocks.

technical background

In modern work and life, it is often encountered that there is no desk for temporary writing and office work, and there is no seat back for resting. Usually, people place books and computers on their thighs and bend down to do so. Writing operations or bending over for a rest, bending over and pressing the legs for such a long time will cause serious discomfort and pose a threat to people's health.

At present, there are already many patents on folding tables and portable tables, and these patents play the role of reducing the floor area of the table and making it easy to carry by storing the table legs. For example, Chinese Patent No. "201410577973.1" discloses a "portable folding table", which realizes the opening and folding of the table board by retracting the outriggers, and realizes the folding and portable function of the table. Another example is Chinese Patent No. "201910364174.9", which discloses a "multifunctional folding table and chair", which can fold the table and seat through the connection of the movable part, so as to realize the folding of the table and chair and the function between the table and the chair. convert. However, these patents often have the disadvantages of large volume, heavy weight, inconvenient carrying, cumbersome storage, and need to be used in conjunction with stools.

Therefore, it is very necessary to design a lightweight, portable and comfortable dual-purpose device for desk and chair to meet people's temporary writing, office and rest needs.

Contents of the invention
