In general, prefabricated cabinets are manufactured using wood or steel for decoration or display. These cabinets are classified as furniture that requires sophistication and require expertise in production and assembly. In particular, they are priced at an unusually high price, such as difficulties in transporting them due to weight or volume, which is entirely borne by consumers. there is a situation.

For the above reasons, recently, the structure and assembly are extremely simplified so that even non-professionals can easily assemble it, and it is delivered in a disassembled state and sold in a way that consumers directly assemble. became

On the other hand, the prefabricated storage cabinet is composed of a support installed from a point spaced apart by an appropriate interval, and a shelf that can be loaded with goods or goods by dividing the support horizontally. It is generally assembled by combining them.

The support has a structure in which a plane is generally bent at a right angle, such as a 'L' or 'L' shape, and a corner portion is disposed to face outward, and a plurality of grooves are formed at regular intervals on the side thereof. The shelf is formed by bending a thin iron plate to form a 'C'-shaped groove inside the side end thereof, and by drilling a number of through holes in the molded side part, a bolt and a nut are mutually assembled at a point communicating with the hole of the support. is a structure that becomes

In this structure, the nut is inserted into the shelf with one hand and then the bolt is fastened with the other hand, but in general, the area where the bolt and the nut are combined is very narrow for using both hands, so it was difficult to assemble quickly and accurately. In addition, since the groove formed in the support has a reduced ability to respond to the load of the object placed on the shelf, deformation such as bending of the support may occur. was accompanied by the problem of

For example, Registration Utility Model Publication No. 20-0228609 "Assembly type angle shelf coupling structure" is published, and the technology is assembling in which the bow piece is integrally bent in all directions, protrudes to the center to form an inner space, and a slot is perforated to the upper surface. It consists of a sphere and a nut sphere of a quadrangular facet, which is installed to be movable at a predetermined interval in the inner space of the assembly sphere and has a bolt hole in the center, and the nut sphere is inserted into the internal space of the assembly sphere by a bolt having a polygonal head groove. Each bow piece formed is welded and fixed to the inner circumferential surface of the groove of the shelf, so that the bolt and nut section are fixedly coupled when assembling the shelf and the support.

However, since the above technology exposes the slot to which the shelf is to be assembled to the outside of the support, the above-mentioned problems are intact.

It is composed of different uses, such as a tray, and has a structure that can be assembled by selecting any one of them.

The above technique solves the above-mentioned problems because the assembling holes are not exposed to the outside while the shelf is assembled. I ran into another problem, such as not being able to.

As described above, the prefabricated cabinet has many advantages such as convenient transportability and low price, but problems such as being delivered without the components necessary for assembly such as bolts and nuts or being easily damaged due to the durability of the prefabricated cabinet occur. The number of consumers looking for it is gradually decreasing.

Accordingly, the present invention aims to provide a prefabricated cabinet that can be easily assembled while minimizing the use of bolts and nuts, and also provides a product with excellent bonding strength and durability even with simple assembly, thereby revitalizing the stagnant prefabricated furniture market.
