Description

Ergonomic desk and chair {TABLE AND CHAIR FOR BIONICS CORRECTING POSTURE}

The present invention relates to an ergonomic desk and chair, and more particularly to an ergonomic desk and chair for a kind of elementary and middle school students.

Recently, phenomena such as drop in sight and humpback of middle school and elementary school students are constantly increasing. Designing rational and ergonomic desks and chairs in response to these situations is already a strong demand and expectation of parents and school teachers .

The occurrence of such negative phenomena has various causes and has serious consequences. From the viewpoint of school hygiene, the posture of putting the center of the body in the upper part of the sciatic joint or the front side is called "dislocation posture". In the above posture, the back part muscles and the thighs are balanced. Placing the center of the upper body on the back of the sciatic joint is called "posture posture". In this case, the back part is required for the back part. Therefore, in the case of the "dislocation posture" in which the posture on the desk is taken, the user often feels fatigue. On the other hand, when the "posture posture" However, recently, most of the students have been studying on the desk with the "avant-garde posture". From the physiological point of view, when the gaze and the object are at a vertical angle of 90 degrees, the image appearing on the retina is the clearest, do. Students have to bow their heads in order to obtain the clearest view when studying. In terms of biological aspects, bones are composed of brittle inorganic matter and flexible organic matter. Physical properties of bones are mainly reflected in two aspects such as hardness and elasticity. In addition, the content and physical characteristics of bones change with age. The characteristics of the bones indicate that they are low in hardness, are flexible, have high elasticity, and are less likely to fracture, while the bones are more likely to deform. If you do not pay attention to your learning and writing posture, you will have symptoms such as humpbacks, curvature of the spine and decreased vision. The doctors of Beijing 4th Hospital have been able to draw these conclusions through years of research and research. In other words, if the learning attitude is wrong over the long term in adolescence, the probability of fatigue, loss of sight and humpback is high, and the probability of developing vertebral disease after adulthood is high.

Recognition and understanding of these negative phenomena are very limited. In recent years, there have been many cases in which students' learning attitudes are wrong, especially when they take a "vanguard posture" and study on their desk. However, they often do not recognize the role of "posture posture". In addition, many emphasize the role of the "posture posture" too much, and feel that the "posture of posture" is also essential. In fact, the "avant - garde posture" helps to write Chinese traditional calligraphy, whereas the "posture posture" is a posture that takes a while from a relatively "avant - garde posture". The precise potential and posture posture are the two most basic postures in learning, which can be arbitrarily switched, and some alternative postures exist in the conversion process. Of course, you can not always maintain one position. These postures can also satisfy the existing learning attitude requirements, that is, the chest maintains a distance of one fist to the edge of the desk, the eye is at a proper distance from the book, and the fingers maintain a proper distance from the tip of the pen.

There are also measures to solve these problems, and people have devised various desks and chairs. For example, one of the recently popular desk and chairs, Shinji Health Study Desk (China Patent Application No. 02354452), the desk can be fixed, the back of the desk is sloped, the brackets are mounted separately, The height of the footrest can be adjusted up / down as well as the pedestal height of the desk leg can be adjusted, and the correct posture - "posture posture" is secured. If the drawback is that the height of the chair can not be adjusted to maintain proper distance from the desk, (Chinese Patent Application No. 03330221), it is convenient to adjust the distance between the desk and the chair when the wheel is mounted on the leg of the chair, The wheel on / off operation is inconvenient, and the distance between the desk and the chair is appropriately adjusted Even if there is to be studied down to the desk, chest concave-shaped chest guard is preventing the proper role. If used in a classroom, if the height between the desk and chair or between the desk and desk does not match, the appearance may be adversely affected. If a new type of student desk (Chinese Patent Application No. 03238636.2) is designed to prevent a kind of drop in sight and humpback, the desk support rack of the present invention is mounted and supported by a chin pedestal and beam, a support for upper / lower adjustment, A single single beam between the beam and the edge of the desk. It supports the upper and lower support. The upper and lower supports are bolted to the positioning hole. The lower control beam is connected by the hinge between the lower edge of the desk and the edge of the desk. About 1/3 of the height of the lower part of the lower part of the chest, and when the upper adjustment beam is tilted backward, the lower part of the chest and the edge of the desk (Chinese patent application No. 03275800) From the edge of the desk or below the chest, and on the front desk with a reading board It intended to maintain the correct "posture potential", because there is no downside if you rest or support the breast unit must also be studied down to the desk and the desk and chair can not be adjusted or moved randomly not also adjust the height.

The above-mentioned desk mainly has the following problems: First, it does not solve the problem in adjusting the height of the desk and the chair, and some existing problems are difficult to supply. When the desk height does not match, The shape of the outer surface is negatively influenced, and the control method is also complicated. Second, there are some problems that can not be solved in adjusting the distance between the desk and the chair. Some existing examples show that there is a problem that the desk and the chair can not be connected with each other but can not be maintained even if they can be connected integrally. Third, the role of the structure such as desk, desk and chair leg, pedestal, desk base rack, reading board, chair back, etc. is difficult to achieve accurate "posture posture" and "posture posture" It is difficult to maintain distance and sight. In addition, there are problems such as a clean arrangement of a desk and a chair, noise generated when moving a desk and a chair, and convenience in cleaning. Some of the grade-based desk drawers lack space for storing books and lack consideration for students.
