Description

3-way table support based on unexposed structure {APPARATUS FOR SUPPORTING TABLE WITH 3 DIRECTIONS BASED ON NON-EXPOSED STRUCTURE}

The present invention relates to a table support apparatus, and more specifically, is provided at the lower portion of the table to be supported, and assembled by configuring a plurality of frame bars and corner brackets are simultaneously connected in three directions without external exposure of the connection site. The present invention relates to an unexposed structure-based three-way table support device that can increase the efficiency of the process and more effectively implement the physical support of the table top.

The table typically consists of a table top plate and a support or support device for supporting the table top plate, and the support device for supporting the table top plate is made in various shapes and structures according to the use, quality, specification, size, etc. of the table.

If the support device is not implemented in one piece, a manner in which individual parts such as a plurality of structures, bars, plates, and the like are interconnected is essential.

In a method of connecting individual parts, joining grooves or protrusions having a corresponding shape are formed at the ends of the individual parts to be connected to each other, and they are fitted or physically close to each other between them. The method of joining connection members, such as a fitting and a bracket, is widely used.

However, in the case of fitting the ends of the individual parts themselves together, if a small damage or breakage occurs in the joining grooves or protrusions, the interfitting structure is deteriorated, and thus, the process of assembling or combining them may be difficult. Even when bonded to the bonding strength is weakened may cause problems in durability.

In addition, in the method of joining the connecting member, a process of preliminarily fixing the joining members is required for the coupling of the connecting member, and the process position may be deteriorated because the correct position must be aligned by a jig or the like.

Furthermore, when the individual parts are interconnected through the connecting member, the connection part or the joint part is exposed to the outside, so that the external aesthetics are not good and the user's clothes or body parts are more likely to be in unnecessary contact with the connection part. Problems can also occur.
