The present invention relates to a chair automatic folding structure for a table having a structure in which the chair is automatically folded up after using the chair.

Tables are used for various purposes, including work tables, meetings, tables for shared classes, and shared tables.

The table usually consists of a top plate and a frame for supporting it, and uses a separate chair separate from the table. However, since the chairs separated from the table move separately from the table, they are easily scattered around the table, difficult to organize and manage, and have a hassle to push the chair into the table after use.

Because of these problems, conventional tables and chairs are used by connecting the frame and the hinge structure to extend the frame and pull out the chair, and when not in use, the table is structured by folding the frame and pushing the chair under the table. Korean Utility Model Registration No. 0311562 further develops this by applying a hinge of an automatic folding structure to a table chair and presenting a table of a structure in which the chair is automatically folded when the user stands up from the chair.

The structure is configured to be foldable in the horizontal direction by at least one frame for supporting the top plate of the table, at least one horizontal frame for connecting and supporting the adjacent vertical frame, and a hinge fixed to the horizontal frame A table equipped with a chair comprising a chair; An auxiliary frame fixedly mounted to the horizontal frame in a vertical direction and having a hollow formed therein; A connection frame fixedly mounted in a vertical side direction of the mounting rod on which the chair is mounted and having a hollow formed therein; The projection frame is inserted into and fixed to the hollow of the auxiliary frame and the connection frame, respectively, and is made of a hinge that is configured to automatically fold in a predetermined direction by mounting a spring therein, so that the table is disposed more efficiently It has the benefit of being able to work and offers the advantage of automatically folding the chair without touching it.

However, the structure is composed of a structure in which the auxiliary frame is coupled to the horizontal frame, the chair mounting rods are coupled to the connecting frame coupled to the hinge of the end of the auxiliary frame so that the weight on the chair acts in the form of twisting back and forth and left and right There is a drawback that the hinge portion is easily damaged by being extended to the hinge portion by the moment force, and one mounting rod serving as a leg of the chair has a disadvantage of being unstable, such as shaking or twisting when weight is loaded.

In addition, the structure is a frame structure is complicated by installing a separate auxiliary frame in the horizontal frame, and when the floor cleaning, etc. hangs, the self-elevation of the chair by the elasticity of the auxiliary frame and the connection frame is used for a long time There is a disadvantage that the folding operation is not properly performed, and there is a limit that is applied only to a chair having a structure without a general backrest, which is inadequate when used for a long time such as a study table used mainly by students.

In addition, the structure is because the folding of the chair by the hinge having a limited folding angle can be moved only in a limited range of the user sitting on the chair has a disadvantage that is very inconvenient when using for a long time, the movement is limited.
