Description

A fold and unfold system for chest of drawers

The present invention relates to a chest of drawers made of synthetic resin, and more particularly, to a folding system for a prefabricated chest of drawers in which an outer case composed of a bottom plate and a column is folded so that the volume is minimized during storage and transportation, and sufficient durability is ensured during use will be.

In general, it is easy to manufacture and light in weight compared to wood or iron, so it can be used conveniently.

Due to the characteristics of the synthetic resin product, each part consisting of a bottom plate, a side plate, and a drawer is injection-molded, and each manufactured part is assembled to manufacture a completed chest of drawers.

That is, disassemble each part. Although it is a structure that can be assembled, since the assembly operation is difficult, the method of assembling the finished product in a production plant and then supplying the finished product to the consumer has been used. Therefore, there was a problem in that a lot of logistics costs were consumed for storing and distributing a chest of drawers with a large overall appearance.

Due to the above problem, in recent years, after the drawer, the bottom plate, and the side plate are delivered in a disassembled state, it is distributed as a method of assembling by the user as needed, but it is difficult to assemble the separate parts. In addition, many problems were exposed, such as complicated disassembly and reassembly when assembled incorrectly, and the need to use a separate tool.

There is a prefabricated chest of drawers disclosed in Korean Patent Publication No. 10-2017-0034035 published on March 28, 2017 in Korea, and these prior names are top plate; a lower plate having a shape corresponding to the upper plate and having a column coupled to the lower surface of the upper plate vertically coupled to the lower surface of the upper plate such that a plurality of them are continuously coupled to the lower part of the upper plate to partition the drawer accommodating space in upper and lower stages; and a first drawer inserted into and out of the drawer accommodating space in the front-rear direction; and a guide roller installed on both sides of the rear end of the lower surface of the drawer and in contact with the upper surface of the lower surface, and installed at the rear end of both sides of the drawer, respectively. The guide protrusion is integrally formed on both sides of the upper surface of the lower plate in the front-rear direction, and the guide protrusion is accommodated inside to prevent the guide protrusion from rotating integrally with the guide roller, and the upper surface of the guide protrusion and a guide means consisting of a guide member in contact with the outer end surface at the same time; further included, when the drawer is entered and exited from the drawer receiving space, the guide roller rotates and the guide protrusion and the guide member are in contact with each other to enter and exit without vertical and horizontal vibration will be.

However, this first name is that the column is vertically fixed to the lower plate, and there is no need to assemble the column separately, but the following problems are raised because the overall volume is large.

First, even if each part is disassembled, the overall volume is increased by the four pillars integrally formed on the lower plate. It occupies a lot of space in the city, resulting in a lot of loss in logistics costs.

Second, many accidents such as breakage occurred because the pillars formed in a protruding state from the lower plate were easily exposed to external shocks during transportation or handling.

Third, due to the characteristics of the product manufactured by injection molding, the size of the mold and the capacity of the injection machine are enlarged in order to manufacture the lower plate and the column integrally, which eventually causes an increase in the manufacturing cost.

The present invention has been researched and developed to solve the above-mentioned conventional problems, and in a chest of drawers consisting of a drawer body, a bottom member, and a side member, the side member is configured to be folded inward as needed so that it can be stored and transported. There is a problem to be solved in order to minimize the occupied space.

Another object of the present invention to be solved is to allow the user to easily assemble or disassemble as needed because the folding of the side member is simple.

The present invention relates to a known chest of drawers each comprising a drawer cylinder, a floor member formed in a plate shape, and side members respectively installed on the left and right sides of the floor member, wherein a coupling space is formed on the front and back sides of the bottom member, and the coupling space is Shaft holes are formed on the front and rear surfaces of the supports respectively formed on the left and right ends, the side members are integrally formed with the pillars and the side plates, and the central axis is formed inside the coupling portions protruding from the lower ends of the pillars. As the shaft is fitted into the shaft hole, the side member is configured to fold the central shaft to the point.

The present invention is configured so that the side member integrally formed with the side plate and the pillar is folded on the upper part of the bottom plate, so that when it is necessary to reduce the volume, such as storage or transportation, when the side member is folded inward, a plate shape is formed. Since the size of the overall external shape can be reduced, the occupied space is minimized.

In addition, since the bottom plate and the side member are integrally coupled, the drawer can be easily assembled by erecting the side member, so that users can easily assemble or disassemble it at home.

In addition, in the state where the assembly is completed, since the coupling of the side member and the bottom plate is strong, the overall durability of the drawer is guaranteed.

In addition, since the side member having a relatively small external shape is separately manufactured and then coupled to the bottom plate, it can be manufactured even if the capacity of the mold or injection machine is not large, thereby reducing the manufacturing cost.
