Description
Affiliated technical field
The utility model relates to the desk stool mechanical assistance educational aid of a kind of energy lifting, it just can carry out lift adjustment table stool height by knowing height, help the student along with growth needs, remain a suitable seat table stool difference of height, to satisfy student's study and physiological requirements.
Background technology
At present, known desk stool is not provided with lowering or hoisting gear, just can not reach the purpose of regulating seat table stool difference of height along with growing tall of student yet, have to make the desk stool of different size standard to university from the kindergarten top class in a kindergarten.But the student can not grow equally high stature along with the increase at age, and always having height has shortly, and does not have " extremely " desk stool of lowering or hoisting gear, extremely difficult satisfy is the student of various heights, the needs of a suitable seat table stool difference of height are provided.The expert has sent the cry of " it is long-range that the tables and chairs that fall behind are left a legacy of trouble to " after the old desk stool old-fashioned to these carries out the science assessment---
" be responsible for the exercise supervision section chief of school hygiene section of Hubei Province Disease Control and Prevention Center of management of school hygiene is opened along pointing out straight from the shoulder in the lane; the height size of some primary school's tables and chairs is constant all the year round now; can not satisfy growing fast of pupil; be unfavorable for student's physical and mental health; constant all the year round desk and chair is compared with ever-increasing height, has fallen behind.Open along the lane section chief and represent, the short partially problem of desk and chair has been a universal phenomenon in the city, has many teachers also to reflect this type of problem ".
" the children's health care head of the department doctor Wang Feng of maternity ﹠ child care center, Hubei Province thinks that then desk and chair not " length " will certainly bring out student's incorrect sitting-pose.Correct sitting posture is shank and thigh, and thigh becomes 90 degree respectively with height.The teenager is in the critical period of body development, and abnormal sitting posture really can cause diseases such as myopia and spinal curvature, and deformity of spinal column can influence the cardiopulmonary blood circulation again, breathes and digestive function, and lung capacity is reduced.”
" in addition; owing to sit uncomfortablely; can often adjust sitting posture, greatly take sb's mind off sth, some teachers can be considered as disrespecting oneself to this " touching " especially; berate greatly; if things go on like this will greatly influence students'interest in learning, and cast a shadow psychologically at it, these harm must cause concern " (draws from Xinhua News Agency Wuhan, reporter Li Peng Xiang, Hou Fangfeng).
We once carried out a stool difference of height test to a sophomoric class of primary school: this class student 30 people, 15 on desk, 15 on stool, through measuring and calculating, the bench that meets student's seat difference of height only is two 4 numbers, accounts for 13% of qualification rate, does not meet student's seat difference of height, what need increase 5-10 centimetre of bench is 13, and disqualification rate is up to 87%.
The seat discrepancy in elevation that the people is short, stool is short, table high two short is high makes classmates once taking lower jaw be shelved on the table, because of drawing back the sighting distance with books, will cause naturally and climb volt on books, is the job state of writing of " eating " word.
The seat discrepancy in elevation that the short two-supremes of people's height, stool height, table one is short is climbed volt and is not write the operation shape because of having suitable mechanical obstacles restriction, making classmates cause " Laolong eats word " to bend over again.
Make " extremely " table stool can be by lifting " work ", know that height just can be by regulating the tables and chairs height, provide one and be fit to that each student conforms to height, its amplitude of accommodation can be from the kindergarten top class in a kindergarten to university, the large span seat difference between table top and chair top that can both adapt to from childhood to old age is a research emphasis of the present utility model.What this problem U.S. did is the automatic lifting tables and chairs, and China has also carried out the research of this respect, but because cost is too high, complex structure is made not according to the standard of desk and chair, is not promoted widely yet so far.
The simple and clear health and epidemic prevention handbook 145-146 page or leaf that Yunnan health and epidemic prevention station writes has proposed following hygienic requirements to desk and chair, has quoted the height standard scale of desk and chair simultaneously, now quotes as follows:
(1), meaning
Desk and chair is an educational aid, and not only the needs that should be fit to impart knowledge to students are fit to write, read a book, have a rest, are fit to human figure, physilogical characteristics, the crowd who is particularly growing---student, and firm, solid, attractive in appearance, guarantee safety, cheap, do not hinder the cleaning requirement.If the desk and chair height is improper, on hygiene, easily produce postural defect, easily, influence physiological function, such as breathing, blood circulation to eyesight influence generation myopia ... influence the students' work ability.
(2), the hygienic requirements of desk and chair
1. table is high, guarantees eye book distance; Table is wide, and guarantee has enough areas when the student writes; Table is dark, makes the student accommodate books and writing case.Generally should equal high half as much again of books or forearm adds pushing.
2. the seat height is suitable for the shank height, and the chair height can not be greater than the shank height, otherwise thigh just is under pressure.Chair is dark, equals 2/3 or 3/4 of thigh length, guarantees that stern knee long about 70% is on seat; Chair is wide to adapt with body wide (shoulder breadth, basin wide).
3. difference between table top and chair top, the high difference with the chair height of the nearly edge of table is a difference between table top and chair top.After the chair height was determined, it was then high for table to add difference between table top and chair top again.Difference between table top and chair top is most important factor in desk and chair, and it has the greatest impact to the posture of taking one's seat.
The height standard of desk and chair draw from December, 1979 People's Health Publisher publish 144 pages in " hygiene of children and adolescents " teaching material of the chief editor of Harbin Medical University, see Table 1.Table 2 is for to have increased tables and chairs height section code according to table 1, and the height pitch-row has been done to delete to 100 centimetres of following heights simultaneously.
