Description

Folding table with improved folding function {Metal folding type table}

The present invention relates to a foldable bed with improved folding function, and more particularly, to a folding bed with improved folding function of a new configuration that can be folded with a simple configuration to ensure convenient portability and stability during use.

In general, most tables are released and used as one table in a state in which the top plate and the legs are attached and fixed to each other. These tables are bulky and take up a considerable volume during transportation and handling, which increases transportation costs, There is a problem that transportation and handling become cumbersome.

In addition, in the case of a table having a foldable top plate, the structure of the legs supporting the top plate is unstable or difficult to adjust, so that the actual support load is often limited.
