Table and chair for bionics correcting posture

Abstract

A bionic positive posture table and chair, including a table (1), a chair (2) or a stool, a footrest is connected to the lower part of the table leg (8); a chair back (17) is connected between the chair back pillars (18), There is a posture device and a mechanism for installing the posture device between the upper and lower parts of the table (1) and the chair (2) or between the table legs (8) and the chair legs (8). A table top lifting mechanism for adjusting the height and inclination of the table top (3) is arranged between the table top (3) and the table box. The table (1) or the chair (2) is easy to move back and forth, the height of the table and chair is easy to adjust, and the structure is simple.

Description

technical field [0001] The invention relates to a bionic upright posture desk and chair, in particular to a bionic upright posture desk and chair for primary and middle school students. Background technique [0002] In view of the increasing trend of myopia and hunchback among primary and middle school students today, designing a more reasonable and scientific desk and chair for them has become the strong desire and requirement of people of insight from all walks of life, as well as teachers, students and parents. It has become a heart disease for many caring people. [0003] There are many reasons for this undesirable phenomenon, and the consequences are serious. From the perspective of school hygiene, the posture in which the upper center of body weight falls on or in front of the ischial tuberosity is called "front sitting posture". At this time, the tension of the back muscles and the thighs are used to maintain balance; After the ischial tuberosity is called "posterio...

AI Technical Summary

Problems solved by technology

For example, Xinzhi Health Study Desk (application number 02354452), which is one of the more fashionable desks and chairs, can be fixed, and the rear table is inclined with elbow rests. The board can also be moved up and down to adjust the height, in order to achieve the purpose of "rear sitting posture" for correct learning posture. The disadvantage is that it is difficult to adjust the chair to an appropriate distance from the table, and it is difficult to change the position or get out after adjustment. If you use another The chair (application number 03330221) has wheels on the legs of the chair, which can easily adjust the distance between the table and the chair. distance, will also lie on the table to study, because the concave shape of the chest will not play much role

If used in the classroom, the height inconsistency between tables and chairs or between tables and chairs will affect the appearance

For example, a new type of desk for natural prevention and treatment of myopia and hunchback (application number 03238636.2), which is equipped with a desk support frame similar to the present invention, a beam connected to it by a chin pad, and an up and down adjustment of the pillar and the back of the desktop. Composed of live joints along the beam and the table edge, the upper and lower adjustment pillars of a single column are stacked front and back, and are fixed with bolts through the position adjustment holes on it, and the lower end of the lower adjustment pillar and the table edge is a live joint. Fixed connection, the width of the up and down adjustment pillar is about one-third of the width of the chest, and it is slightly inclined backward. From the lower end of the time to the edge of the table or slightly lower than the lower end of the chest, there is a reading board similar to a bookshelf on the front table. People can't get down, and they want to achieve the goal of correct "front sitting posture". The disadvantage is that people sit on the chair and front Leaning back, the table is easy to shake, and it is difficult to get in and out and change the sitting position, and the height of the table and chair cannot be adjusted. Naturally, it is difficult to achieve the purpose

For example, a reading and writing desk and chair for correcting sitting posture (application number 03275800), which can adjust the distance between the desk and chair according to the posture requirements and connect them together, aiming to achieve the goal of correct learning posture "front sitting posture". Do you have no support in front of your chest, or do you lie on the table to study, and the tables and chairs cannot be adjusted freely, and the height cannot be adjusted

[0006] These desks and chairs, in summary, the main problems are as follows: First, some desks and chairs have not solved the problem of height adjustment, and some have solved it, but it is difficult to popularize, and they are still placed in the classroom at the same height, because the height adjustment is high. , short and short, very unsightly, and the adjustment method is very complicated

The second is that some of the distance adjustment between tables and chairs has not solved this problem, and some have basically solved the problems that the tables and chairs cannot be freely connected together, and those that can be connected together are difficult to maintain.

The third is the role played by the table top, table and chair legs, elbow rest, table frame, bookshelf, chair back and other structures. The correct "front sitting posture" and "back sitting posture" and the transition posture between them have not yet been achieved Easy to exchange and the purpose of the eyes and the book board are always at the best distance and viewing angle

In addition, insufficient attention has been paid to the neat arrangement of desks and chairs, the sound of moving desks and chairs up and down, and the convenience of cleaning. Some grade desks and boxes have too little space for books, and children have not been considered much. It is not convenient to move
