Abstract

At present, most students in middle and primary schools have poor habits of lying on desks to read and write, the normal development and the health of the body are influenced, and the occurrence of myopia and spinal column deformity is caused, so the normal development of the body and the school record can be influenced. The invention relates to an anti-fatigue myopia-prevention spinal-column-deformity-prevention multifunctional school desk and chair, which has the major advantages that a chair adopts design form that a chair back is backwards inclined, in addition, an arc-shaped head pillow, an arc-shaped neck pillow and an arc-shaped waist supporter capable of forwards, backwards, upwards and downwards moving are respectively arranged at the upper and lower sides of the inner side of the chair back, and the gravity load borne when the body is in a backing-free state is reduced. According to different backward inclination degrees of the body, the combination angle and the height among all components of the anti-fatigue myopia-prevention spinal-column-deformity-prevention multifunctional school desk and chair can be freely regulated, the body unbalance and the fatigue caused by upper body backing-free and supporting-free conditions can be thoroughly solved, so that the anti-fatigue myopia-prevention and spinal-column-deformity-prevention goals are achieved. The anti-fatigue myopia-prevention spinal-column-deformity-prevention multifunctional school desk and chair has the advantages that the operation is simple, the structure is reasonable, the use is convenient and flexible, the space of a classroom is also saved, and the wide popularization can be easily realized.

Description

Antifatigue, myopia prevention, anti-vertebra modification multifunctional desk and chair

Technical field

The present invention relates to a kind of antifatigue, myopia prevention, anti-vertebra modification multifunctional desk and chair.

Background technology: student uses at present desk and chair simplicity of design, style ossify, cannot solve student lies prone in the bad habit of desk learning, the inadaptable modern demand that comprehensively improves students ' quality education, affect the normal development of health, damage student's physical and mental health, cause myopia, the sick generation of the deformity of spinal column, thereby affected student's school grade.

The bad habit of lying prone on desk when the desk and chair that current student uses cannot solve student's reading and writing.The invention has the advantages that the sweptback design concept mode of Chair back that adopted, chair back inside front and below installed respectively movably arc neck pillow, arc headrest and curved waist holder additional, the stressed load that has born head, neck and waist, the chair back has a teeth groove shape head to be connected to come the angle that adjusting back tilts forward and back with chair.Another advantage of the present invention is the reasonable combination collocation form of desk and chair, and table leg and chair legs have all adopted grooved slideway moving up and down, and the connection between desktop and table leg, between seat and chair leg has all adopted teeth groove type carriage; Desktop and seat can regulate arbitrarily upset in the angle of 130 degree, desktop and seat can stand on table leg and chair leg outer side and inner side, fatigue when elbow is unsettled while writing in order to solve has designed movable teeth groove type elbow-supporting plate at the middle part of chair back inner side, has realized the comfortable object of myopia prevention and vertebra modification in advance again that is seated.

Summary of the invention

Can not solve the lie prone bad habit of on desk reading and writing of student in order to overcome existing desk and chair, the present invention has adopted the sweptback design of the chair back, saving studying space simple to operate, flexible and convenient to use, has realized and has not only been seated comfortable but also can reaches pre-myopia prevention and the object of preventing the deformity of spinal column.

It is to have adopted the chair back to the incline design form of reading and writing of layback according to the physilogical characteristics of Human physiology that the present invention solves technical scheme that its technical problem takes, according to the chair back angle of reclining backward, make on each stress point that touches chair that the position of each load-bearing of health loosens completely, allow health in a kind of zero load light state free of a burden completely, both hands are upwards mentioned past direction in one's arms by desktop and are pulled desktop, press the good desk of different adjustment of health height and height and the gradient of chair, just can reach antifatigue, myopia prevention, the anti-deformity of spinal column has realized light the destination of study.

The invention has the beneficial effects as follows and overcome the physical fatigue that the desk and chair of current use cann't be solved and a difficult problem on the desk reading and writing of lying prone, and realize thoroughly the object of antifatigue, myopia prevention, the anti-deformity of spinal column.

Below in conjunction with drawings and Examples, the present invention is further described.

Fig. 1 is left view of the present invention

Fig. 2 is the left view figure after table of the present invention, seat are turned up respectively

Fig. 3 is top view of the present invention and front view

In figure: 1 chair back, 2 holder elbow handrails, 3 seats, 4 teeth groove shape carriages, 5 chair leg flute profile inner slides, 6 put bookcase, 7 cross members, 8 cover pin, 9 seats, 10 tear flute profile carriage open, 11 table leg flute profile inner slides, 12 pin holders, 13 curved waist holders, 14 arc neck pillows, 15 arc elbow-supporting plates, 16 put pen container, 17 bar shaped book clamps, 18 bolt shaft, 19 bolt shaft, 20 table leg flute profile external slideway, 21 chair leg flute profile external slideway, 22 bolt shaft, 23 bolt shaft, 24 teeth groove type heads, 25 bolt shaft, 26 flute profile loose slots, 27 bar shaped loose slots, 28 arc headrests.

Detailed description of the invention
