Technical Field

The invention belongs to the technical field of tables and chairs, and particularly relates to a lifting table, an integrated table and chair device and a group sitting posture intervention method.

Background

The table is a necessary product accompanying the small to large of us, especially in the student age and the working age of us. In order to meet different use requirements, design schemes of the table are various, lifting is the most common one, however, the existing lifting schemes mostly focus on lifting of the table top, and the table is almost certainly matched with a chair for use. In real life, the chair is often placed everywhere, especially when cleaning, in addition, for collective occasions such as classrooms, libraries, meeting rooms and the like, the normal walking of the chair is often influenced, and a large number of tables and chairs further cause that the cleaning cannot be smoothly carried out. In addition, for the current lifting table, the height of the table can be matched with different heights at different stages, but the regulation and control mode is inconvenient, and a user cannot be in a normal sitting posture state in the regulation process, generally, the table is found to be not ideal after regulation, and the table needs to be regulated repeatedly for several times. In addition, the existing liftable tables and even chairs can not promote students to form good sitting posture habits, and if the students are in the stages of long body, good mobility and poor self-control, the sitting postures of the students can not be scientifically guided, the consequences such as myopia, spinal deformation and the like can be caused.

step 2, obtaining comparison coordinates: on the measuring date, when the individual is in the sitting state, the control system controls the treading device 6, the upper table plate 1 and the seat plate 39 to be restored to the original state, then the height of the seat plate 39 is adjusted, the user keeps the legs close, the waist and the back are straight, the two arms naturally droop, in a rectangular coordinate system K, the distance meter 49 is used for measuring the top point of the knee, and a comparative coordinate D1 is obtained

Step 3, in the same rectangular coordinate system K, according to the comparison coordinate D₁Obtaining the current leg length data, and comparing the comparison ratio with the coordinate D₁And a reference coordinate D, obtaining the difference value Delta D of the two coordinates, thereby obtaining the data change of the legs of the individuals on two adjacent measurement dates.

For the group in the growth period, the height information is regularly collected and replaced, and the table and chair parameters are favorably readjusted, so that the state of the integrated table and chair device meets the growth requirement of the body of the group, and the group always keeps a scientific and reasonable sitting posture in the growth process. In addition, the leg length data of the individual sitting posture is collected regularly, the body growth condition can be monitored, and whether the desk and chair device in the current seat state is matched with the height data of the current individual can be detected, so that adjustment can be made in time before the next-stage data is collected. For the intervention party, the collected individual height data is used as basic data for adjusting the table and chair device, so that unified regulation and control of all the seats are realized, each individual can keep a scientific and reasonable sitting posture, blind regulation of the individual aiming at self comfort is avoided, errors in regulation are avoided, and continuation of wrong sitting postures is avoided. The method can perform unified intervention on the group, so that the time for correcting the sitting posture of the group can be effectively saved, the method is more scientific and reasonable, and the group can quickly establish a correct sitting posture idea and form a good sitting posture habit.
