Description

Flat-lying afternoon nap desk

Technical Field

The invention relates to a teaching apparatus, in particular to a student desk 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 back and forth 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 back, and are heavy in the humpback and bend over, 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 up to now, and although design schemes of dual-purpose desk and chair and folding desk and chair are recently developed, the desk and chair are transformed into a reclining chair, the structure is very complex, the manufacturing cost is high, although the afternoon nap of a lying desk is improved, the body of a person lying aslant cannot be unfolded, the effect of thorough relaxation cannot be achieved, and the development and the growth of the body of teenagers are still not facilitated. In order to enable students to lie flat for afternoon nap, few schools also think of a method for enabling one student to lie on two desks for afternoon nap, but half of the students are not sleeping on the desks lying down, and in addition, the students are unsafe to lie on the desks to sleep and are easy to fall and hurt. Therefore, a flat-lying afternoon nap desk has recently appeared, movable side plates are arranged on two sides of the desk, the side plates are laid flat during afternoon nap and supported by naturally drooping support legs or a set of complex linkage device, and the desk is complex in structure, inconvenient to operate, high in manufacturing cost, difficult to use and low in practical value. The afternoon nap desk for class and afternoon nap in a classroom, which is low in manufacturing cost and simple and convenient to use, is still an urgent need of the whole society.
