A leaning tool for studying to correct posture based on ergonomics

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

  Designing posture-correcting tools for studying to correct the tendency of myopia and stoops in elementary and junior high school students to continue the increasing trend of myopia and stunning in the future. Doing this has become a strong aspiration for many experts, many teachers, children and parents, and at the same time, it is also a problem for those who have a heart.

  There are a variety of causes for these unhealthy phenomena and the consequences are significant. From the viewpoint of school hygiene, a posture in which the center of gravity of the upper body is placed on or in front of the sciatic tuberosity is referred to as a “front sitting position (a posture where a person sits on the end of a chair)”. At this time, maintain balance with the muscles and thighs of the back muscles. The posture in which the center of gravity of the upper body is placed behind the sciatic tuberosity is said to be “rear sitting (the posture of sitting on a chair)”. Your back will always rest on the backrest. It is clear that the “front sitting position” in which the face is brought close to the desk with a stupid tendency tends to get tired, and the “rear sitting position” is hard to get tired. Currently, however, students are generally studying with the “front sitting” position, with their faces close to their desks. From a physiological point of view, the image on the retina is most clear when the angle between the line of sight and the object to be viewed is vertical, and this angle is called the physiological viewing angle. While students are studying, they have to bow their heads to find the most clearly visible angle. From a biological point of view, bones are composed of hard and brittle inorganic components and flexible organic components, and the physical properties of bones are mainly expressed in terms of both hardness and elasticity. The physical properties of the material change constantly with age. For example, the bone quality characteristics of children and adolescents are low in hardness, flexible, large in elasticity, and difficult to break, but on the other hand, it is easy to deform, so it can be used for learning and writing. Long-term carelessness can cause symptoms such as stoop, scoliosis and myopia. Liu Zhi-Ming, the doctor of Beijing Fourth Hospital, after many years of hunting, when the youth continued to learn incorrectly for a long time, not only is it easy to get tired, myopia, become stooped, but still not focused on people Concludes that causes more serious consequences. These students become adults with a high incidence of cervical spondylosis after adulthood.

  However, this unhealthy phenomenon is not yet fully understood. Traditionally, students' learning attitudes are not correct, and in general, they are generally taking a “front sitting position” and studying with their backs close to their desks. While there are those who have tried to improve this posture through various thoughts but still do not understand the action of `` rear sitting '', correction is overwhelming, emphasizing only the action of `` rear sitting '', `` Some do not understand that "front sitting" is essential and can be improved to the correct posture. In fact, without the “front sitting position”, it is disadvantageous to the use of Chinese traditional brushstrokes. The “rear sitting position” still has a problem of studying with the face close to the desk in a stupid manner compared to the “front sitting position”. Moreover, there are two basic postures of learning correct “front sitting” and “back sitting”, and they must be able to change freely with each other, and there are several alternative postures in the process of changing Should. Because a person cannot sit in one kind of posture. Moreover, all of these postures require the traditional “Sanichi” learning posture: one fist from the chest to the edge of the desk, one from the eye to text, and one finger from the pen tip. It is possible to leave or is advantageous for this requirement.

  There are measures taken as a means to solve the problem, but the results are not so good. A variety of devices for myopia and stump prevention treatment have been invented, but there are some problems, although they are effective. The main problems are that there is no abdominal plate, the adjustment column is fixed vertically and cannot move back and forth, it is disadvantageous to lean forward, applying force, the adjustment column blocks the line of sight when leaning back, There were problems such as not being able to hold the jaw firmly with the adjustment spring, and all did not help in forming the appropriate “front sitting” and “back sitting” and learning posture in between.

  In view of the shortcomings of the prior art, the object of the present invention is to ensure that the user always has a proper "front sitting position", "rear sitting position" and a learning posture between them, and a free "change sitting position" to the user, and is less tiring. An object of the present invention is to provide a study leaning tool for correcting posture based on the above.
