Description

Multifuntion jointed desk/chair for preventing hunchback and myopia

The utility model proposes a kind of increased Collapsible multifunctional disjunctor table stool that can prevent hunchback and control myopia.Be particularly suitable for as the children's that are in the growth developmental stage a study table stool.

The custom-designed study of the promising children of a there be limited evidence currently of table stool.Especially children learn and when doing the homework at home, normal utilize the adult with desk, dining table or to be sitting on the small stool with common square stool serve as to see written word, this is not only inconvenient, and often causing adverse consequences: (1). table stool height does not meet children's organization of human body requirement, if desktop is too high relatively, it is painstaking to write, and also can't ensure the reasonable visible sensation distance of eye and desktop, very easily causes children's pseudo-myopia.If the stool face is too high relatively, children need bend down body and write, and make backbone be in case of bending, will cause hunchback for a long time.(2). the split of table stool, table stool level interval is indefinite, influences children and sits the gesture attitude, impairs the straight and upright vigorous and graceful bodily form of back back of growing up.(3) though. have some to be the table stool that children design, the stool face is generally level, and femur is the level of state substantially during use, it is sagging that shin bone and fibula are nature, and backbone directly bears body weight, the lumbar vertebrae cantle, thoracic vertebrae and cervical vertebra lean forward, and present curved position, as Fig. 2.This result causes physical fatigue on the one hand, makes learning efficiency low.On the other hand, also be one of origin cause of formation of causing bow-backed and pseudo-myopia.For this reason, be necessary the novel table stool that children grow up and grow that meets of the science of developing.

Chinese patent ZL85201572 proposes backrest, chair and the adjustable desktop of high low dip that seat is adjustable, but complex structure can not fold, and it is bigger to take up room, and inconvenience is placed in the family.The piece desk and chair that CN87211052u proposed, though collapsible, structure is also very complicated, it is bigger to adjust difficulty.In addition, make the robust structure part, be difficult for to realize stepless heightening, adjust the back in case stressed with belt, the table High variation, and, use the belt can be easily broken and dangerous for a long time because of fatigue.

It is bow-backed near-sighted with control that the purpose of this utility model provides a kind of energy prevention, multi-functional disjunctor table stool simple in structure.Not only make the user can keep the best gesture position of sitting, prevention is bow-backed and near-sighted, makes the people take health and unfolds, and feels comfortable, helps to concentrate one's energy, and improves learning efficiency, and can be suitable for the variation of different users's health, goes back safety and firmness simultaneously, and saving takes up room.

In order to achieve the above object, the utility model is broken existing table stool design general layout, adopt ingenious and simple and direct mechanism, on research children's development characteristics and a series of data basis, propose a kind of practical design scheme of science economy: table stool one; Table stool relative spacing and relative altitude are adjustable; Desktop can be moved the angle of inclination; The stool face tilt, and have to the knee device; Integral body is accordion structure.Desktop and foreleg are "T"-shaped structure, and the table bottom is provided with supports the knee device, and it is D score shape structure with table portion.Stool portion is " * " shape structure, is connected with table portion by hinge.Table stool main frame be "

" the shape structure.In addition, on the table also with collapsible music easel, the fixing card of spring clip and electronic organ.(seeing Fig. 1, Fig. 4, Fig. 5)

The utility model is compared with existing table stool has following function and good effect:

1. the utility model, be equipped with to the knee device foreleg bottom, and the inclination stool face angled with level is housed on the cant beam.Support the combination of knee device and inclination stool face, the stressed decomposition of user's backbone (as Fig. 3), gravity center of human body's reach.For keeping one's balance, backbone is straight and upright state naturally.This seat gesture attitude can be prevented hunchback for children, keeps the vigorous and graceful bodily form, as long-time use, the effect of the pseudo-myopia of preventing and treating is arranged, and can also make the people take health simultaneously and unfold, help the student to concentrate one's energy, and improves results of learning.

2. the utility model, table stool disjunctor by the guiding mechanism between the guiding mechanism between desktop and foreleg and stool face and cant beam, can be adjusted the relative spacing and the height of desktop stool face, thereby avoid children to cause irrational seat gesture and sighting distance.Like this, be not only applicable to the use in school-ager's all ages and classes stage, needn't change a stool, and be applicable to different users's the height variation and the specific demand of special type because of age growth.

3. in the utility model design, desktop and foreleg are hinged, can adjust angle, should be used as writing desk.Simultaneously, with music easel and electronic organ fixture, spring clip is housed also on the music easel on the desktop, therefore, can be used as qin table, fine arts frame and engineers and technicians again and chart with table.Easy to use.

4. the utility model design depends on the calculating of science, and is rational in infrastructure.Desktop, stool face, support the knee device and main body frame is folded form.Move facility during use, safety and firmness.Folding whole small and exquisite, be convenient to deposit.Be suitable for family and use, and cheap.
