Description

FRAME ASSEMBLY SYSTEM FOR FURNITURE

The present invention relates to a frame combining system for furniture. More specifically, the present invention relates to a system for combining furniture frames constituting furniture such as a desk or table or dining table.

For example, one method for mutually joining a furniture frame constituting a desk or a table or a dining table is to weld the frame. However, this frame joining method is a specialized technique requiring a welding machine and an experienced welder, and it is difficult for an unskilled person to access.

Another method is to fasten the frames to each other using bolts and nuts, which are conventional fastening means. However, such a coupling method has a problem that the furniture frame is easily separated even with a small impact due to a weak coupling force.

In order to improve this, the joining structure of the furniture frame according to the prior art is to form a protrusion on one frame and to form a hole through which the protrusion is fastened to the other frame, thereby mutually coupling, through which a prefabricated metal support leg is provided. The table is organized.

In addition, it is known that the joining structure of the furniture frame according to the prior art can use a connector, which is a kind of medium, through which a table with a prefabricated metal support leg can be easily constructed.

However, the coupling structure of the furniture frame according to the prior art is a structure in which the connector and the bracket must be coupled to each frame, which may have a weak coupling force in terms of structural rigidity.
