Description

  The present invention relates to a study backless for correcting posture based on ergonomics, and more particularly to a study backrest for correcting posture based on ergonomics for elementary school students.

  Japan is now human-oriented, and it maintains its strategy of promoting motherland through science and education, while phenomena such as myopia of elementary school students and junior high school students and the back of a child continue to increase. In order to design a study backrest with posture correction, it has become a strong desire of various experts and many teachers and many children and family heads.

  The reason why it becomes bad from various viewpoints is that the subsequent results are terrible. Speaking of school public health, it is said that the center of mass of the upper body is placed on the sciatic nodule, or the front posture is “sitting on the chair's head”. To maintain. After placing the center of mass of the upper body on the sciatic tuberosity, it is said to be “sitting down after the chair”, and the back is always reliable. It is clear that it is easy to get tired and become “sitting down after the chair” by putting the face close to the desk with a stupid face and making it difficult to get tired. . In the past, students generally take a "sitting posture on a chair" and study with their backs close to their desks. From a physiological point of view, when the line of sight is perpendicular to the object of interest from the eye, the image formation is clearly changed on the retina, which is called the physiological viewing angle. Students studying only bow their heads to find a wide viewing angle. From a physiological point of view, bones are composed of hard and brittle inorganic components and flexible organic components. Bone physical properties mainly represent hardness and elasticity, and for different bone composition content and bone physical properties. It changes with age. For example, the bone quality characteristics of children and adolescents are low in hardness and flexible, so they are highly elastic, hard to break but easy to deform, pay attention to postures for long-term learning and writing. If not, writing posture may cause symptoms such as stoop, scoliosis and myopia. Mr. Liu Shi Ming, the doctor of Beijing No. 4 Hospital, has been searching for many years. Finally, if the youth's long-term learning attitude is not correct, people are not easy to get tired, myopia, become stooped, and the result is not focused on people. Students conclude that after adulthood, they are a high incidence of cervical spondylosis.

  Understanding the depth of this failure phenomenon is still limited. Traditionally, students are not learning correctly, so they generally take a “sitting posture on a chair” and study with their faces close to their desks. Improving posture and still not understanding the effect of “sitting posture after chair”, while correction is overwhelming, but still improperly highlighting the action of “sitting posture after chair” I do not feel that it is indispensable for "the posture that sits on the front of the chair", and I can improve it to the correct posture. In fact, if you don't have a stance to sit on a chair, don't use Chinese traditional brushes. Instead, use a stance to sit on a chair instead of sitting on a chair. However, there is also a problem of studying with the face close to the desk in the past. In addition, there are two basic postures for learning, the posture of sitting on the right and left of the correct chair, which should be freely interchangeable, and there are still several alternate postures in the exchange process It is because a person cannot sit in one kind of posture all the time. People can't keep one kind of posture for a long time. What's more, these postures can reach the traditional "31" learning posture requirement, that is, one fist from the chest to the edge of the table but one inch from the eye to the text, and the finger of the hand is pen There is a benefit in being one inch away.

  It is not useful at all as a means to solve the problem. People have also invented a variety of devices for myopia and stump prevention treatment. Although it can play an effective role, some problems have been pointed out, but mainly because there is no abdominal plate, the adjustment column is fixed vertically but cannot move back and forth, so it does not help by applying force before It ’s the back of the adjustment pillar that blocks the line of sight, and the adjustment spring does n’t leave you as long as the jaw, but it ’s all about the right “sitting in front of the chair” and “after the chair. It does not help in forming a sitting posture "and a learning posture in between.

  The present invention is in a much more appropriate "sitting in front of the chair" and "sitting in the back of the chair" and learning position between them, and is free to "sit" against the disadvantages of the prior art. The purpose of this study is to provide a study backrest that can change posture and correct fatigue based on ergonomics.

  Employing and technical means to solve the above problems, including a frame with mounting table with a table back, sit in a chair at the back of the table with the correct learning posture, and the chest abdomen is on the edge of the table and under the abdomen from the chin A proper "sitting posture before the chair" and "sitting posture after the chair" and learning posture between them, with the body between the table edge and one fist between the cut and thighs and slightly facing but to reach, also it is an adjustment device freely "sitting posture change".
