Description

Novel ergonomic folding bed for noon break of students

Technical Field

The utility model relates to the field of folding beds, in particular to a novel ergonomic folding bed for noon break of students.

Background

As primary and secondary school students are in the growing period, the hand strength is weak, and the height difference is large, so that how to design a folding bed which is easy to open, appropriate in height and small in occupied area becomes the design key point in the field. At present, in order to save space, the folding bed is mostly hidden, the main hidden folding bed form is pull type, the pull handle is short in height and can be suitable for all primary and secondary school students, but the pull type generally needs to hold the pull handle by hands and lift the pull handle first and then pull the pull handle out, and the pull type is used for students with weak hand strength and needs to rely on the help of teachers or other students. Similarly, some retractable hidden folding beds exist at present, but the retractable hidden folding beds are too simple, students with small strength cannot put down and fold up the bed plate independently, and the students cannot exercise the hands-on ability of the students in middle and primary schools well while using the retractable hidden folding beds. Moreover, even when a plurality of students fold and unfold the folding bed together, the bed board has certain weight, so that the folding bed is dangerous for primary and middle school students, and the folding bed is easy to automatically unfold and fall after being folded and stored, thereby having high potential safety hazards. Therefore, a folding bed in a retractable manner needs to be designed, so that the occupied space of the folding bed is reduced while the use safety of primary and secondary school students is ensured to the greatest extent, the use experience is improved, and the independent operation capability of the primary and secondary school students is enhanced.
