Bionic desk and chair for correcting posture

Abstract

A bionic and posture-correcting desk and chair, including a desk and chair or stool, which are separate or combined. The bottoms of desk legs are connected with a footrest, and a chair back is connected between supports of the chair back. At the upper and lower parts of the desk and chair are disposed with a posture-correcting device and a mechanism for fixing the posture-correcting device. The posture-correcting device allows users to maintain the correct “forward sitting position” and “backward sitting position” or a sitting position therebetween all the time. The bionic and posture-correcting desk and chair ensures sitting positions which are comfortable and unlikely to cause fatigue and are easily adjusted.

AI Technical Summary

Benefits of technology

[0019]Advantages of the invention are summarized below: 1. According to the bionic principle, the lower end of the single-column lower adjustable pillar, similar to the desk backrest sternal plate, extends to the lower part of the abdomen and the bottom of the desk box (desk box baseplate) from the chest to the desk edge. The fixed connection between the lower end of the lower adjustable pillar and the desk edge is changed to the moveable connection. The upper adjustable plate between the desk backrest sternal plate and the ventral plate is inserted in a transversal gap of the adjustable plate cover or the adjustable cover of the mounting plate. The lower adjustable plate moveably connected with the lower end of the sternal/ventral plate is directly or indirectly moveably connected with the desktop lifting mechanism and the bookrack lifting mechanism to make the desk and chair as a whole. The desk or the chair is disposed with a footrest. A chair back support adjustment mechanism and a chair back adjustment mechanism are disposed on the chair including the layer covers, tracks, desk and chair seats and foot button. The problem that students study by bending over the desks is solved by using such structure. If the user places his feet hardly on the footrest, the sternal/ventral plate and the chair back are against the chest, abdomen, waist and back. The user is clamped in the middle. He can bend over or lean behind at will. The desktop can be flat or inclined. The bookrack can be lifted with the desktop and remains the optimal distance and angle with eyes, therefore a reasonable space will be formed between the head, eyes, neck, chest, abdomen, waist, back, buttocks, elbows, legs, feet and the desk and chair. Users will always be at the correct “forward sitting position” or “backward sitting position” or any position in between. In addition, the position can be changed at will and stud

Problems solved by technology

It is apparent that the forward sitting position is likely to cause fatigue while the backward sitting position is not.

If students do not care about their sitting positions for study or writing, they are more likely to suffer from fatigue, short-sight and hunchback.

After the desks and chairs are adjusted, they are not suitable for users with different height.

Furthermore, it is complicated to adjust the desks and chairs and they are less durable if they are adjusted too much; 2. The distance between the desks and chairs has to be adjusted by adjusting the adjustable tube underneath and afterwards the desks and chairs have to be fixed by screws.

After the desks and chairs are adjusted, they are not suitable for users with different weight.

It is not easy for users to change the correct forward and ba
