Abstract

A bionic posture correcting frame for leaning on in study comprise a body composed of a frame body and an installing frame. When a user sits on a chair behind a desk, an adjusting mechanism is provided on the body which is located between the desk edge and the breast and the abdomen of the user, and between the chin and a position from the lower abdomen to the little over the thigh. The adjusting mechanism is a fist away from the desk edge to realize a right front-position, back-position and study posture between the two positions and can be converted optionally. The mechanism can match with general desks and chairs or bionic posture correcting desks and chairs, and can effectively ensure that a reasonable activity space is formed between the desk and the chair for parts of body such as the head, eyes, the neck and the breast and so on.

Description

A bionic posture learning stand

Technical field

The invention relates to a bionic posture learning learning frame, in particular to a bionic posture learning learning frame for a primary school child. Background technique

Today, adhering to the people-oriented, science and education strategy of rejuvenating the country, the phenomenon of myopia, hunchback and other phenomena in primary and secondary school students is on the rise, designing a scientific and applicable positive posture learning framework, which is the people of insight and teachers and students from all walks of life. And the wishes and requirements of the parents, but also a lot of heart disease.

The causes of this undesirable phenomenon are multifaceted and the consequences are serious. From the point of view of school hygiene, the posture in which the upper body weight falls on or in front of the ischial tuberosity is called the "pre-sitting position", at which time the balance of the back muscles and the thighs maintains the balance; After the ischial tuberosity is called the "post position", the back must have a leaning. Obviously, the "pre-position" on the table is prone to fatigue, and the "post-position" is not easy to fatigue. However, at present, students are more commonly taking the "front seat" posture and learning at the table. From a physiological point of view, when the line of sight is at a perpendicular angle to the object being viewed, the image on the retina is the clearest, called the physiological angle of view. Students can only bow when they are learning to pursue the clearest perspective. From a biological point of view, the bone is composed of hard and brittle inorganic matter and flexible organic matter. The physical properties of the bone are mainly manifested in two aspects of hardness and elasticity, and the content of different components in the bone and the physical properties of the bone. It is constantly changing as people age. For example, the bone characteristics of children and adolescents are small, flexible, and elastic. Although they are not prone to fractures, they are easily deformed. If you do not pay attention to learning and writing posture for a long time, it will cause symptoms such as hunchback, dorsiflexion and myopia. After many years of exploration, Liu Zhiming, the attending physician of Beijing Fourth Hospital, finally came to a conclusion: The long-term learning posture of adolescents is not correct, not only easy to fatigue, suffering from myopia, hunchback, but also a more serious consequence has not been valued, that is, these students Adults will be a high incidence of cervical spondylosis.

The depth of understanding this kind of bad phenomenon is still very limited. Because the students are not correct in their learning postures, especially in the "pre-sitting posture" posture, they are learning on the table. Some are trying to improve this posture. They have not realized the role of "post-sitting posture". Overcorrection, one-sided emphasis on the role of "post-sitting posture", has not yet felt that "pre-position" is indispensable, and can also be improved into a correct posture. In fact, there is no "pre-position", which is not conducive to the use of traditional Chinese brush. The "post-sitting position" is a kind of posture of "pre-position". At present, there is also the problem of studying on the table. And the correct front and rear sitting postures as the two basic postures of learning should also be interchangeable at will, and there are some alternate postures in the process of interchange, which should also exist, because people can not always Sitting in a pose. And these postures can be used to achieve the traditional "three one" learning posture requirements, namely: the chest is a punch along the table, the eye is one foot away from the book, and the finger is one inch away from the tip of the pen.

The measures to solve these problems are not very effective. People have also invented a variety of devices for preventing myopia and hunchback. Although they have played a certain positive role, there are still some problems, mainly because there is no web. The vertical fixation of the adjustment column cannot be moved back and forth, which is not conducive to leaning forward, backward. Relying on the adjustment column blocked the line of sight, and the adjustment spring could not hold the chin, etc. Conducive to the formation of the correct "front seat" and "post position" and the learning posture between them.

Summary of the invention

In view of the deficiencies of the prior art, the present invention aims to provide a bionic posture learning stand, which can ensure that the user is always in the correct "front seat" and "back position" and between the learning posture, and free Replacement, not easy to fatigue.
