Description

Method for realizing afternoon nap function by desk and chair and afternoon nap desk and chair

Technical Field

The invention relates to a teaching apparatus, in particular to a student desk and chair for a classroom.

Background

Afternoon nap is essential for teenagers. However, due to the existing conditions, most middle and primary schools cannot provide a nap facility for students, students who are not far away from home can only go home for nap in the afternoon break, and the time for getting on and off the road is delayed for a lot. More difficult, students far away from home can only lie on a desk to sleep, and can have a rest a bit, but in the long run, the students are slightly sore in the waist and painful in the back, and when the students are heavy, bend in the back, the cervical vertebra is deformed, and the health of children is seriously affected. For a considerable period of time, the best solution has been to simply retrofit existing facilities to provide a nap function without increasing floor space. However, the difficulty in realizing the function is great, so that no feasible solution is available, and although design schemes of dual-purpose desks and chairs and foldable desks and chairs are recently developed, the single chair or the combination of the chair and the desk is transformed into the reclining chair, so that the structure is complex, the manufacturing cost is high, the change and adjustment time is long, the difficulty is large, the reclining chair is inconvenient for children to use, the size of the chair is small, the reclining chair is unsafe and uncomfortable, the design schemes are difficult to be accepted by teachers and parents, and the existing various unhealthy and unsafe afternoon nap modes can be taken as a measure of convenience in a long time.
