The present invention relates to a leveling device for system furniture, and more particularly, it is possible to easily adjust the height of a vertical frame or post of the system furniture, and is stably fixed to the ceiling in a state in which the height is adjusted so that the system furniture can fall The present invention relates to a leveling device for system furniture that can prevent and improve workability by more easily adjusting the height and performing fixing work using a power tool or the like.

BACKGROUND ART In general, furniture is one of the important living tools that are indispensable in order to smoothly lead human life in a living space. In other words, furniture makes human life more prosperous and comfortable living space, and through furniture, they can realize the living image or lifestyle they drew.

Furthermore, reflecting the modern era of individualization and diversification, space is directed according to various styles or preferences, and furniture plays a decisive role in realizing such individual styles and preferences.

In such furniture, a wardrobe, hangers and shelves are needed to hang a blanket and various types of clothes or to store various small tools used indoors along with changes in human living life.

Until recently, each household had a wardrobe to store clothes and blankets so that clothes and blankets could be stored together. It has the disadvantage of not being able to change the arrangement of furniture indoors, and there are many restrictions due to moving, such as a wardrobe, etc.

Because chests and cabinets are made of wood and always occupy a certain amount of space, they are bulky and difficult to transport. .

Interior furniture has the advantage of being relatively simple to assemble and install by means of frames and shelves so that it has an open structure without a door by completely changing the concept of furniture with doors of the same weight as the existing wardrobe or chest of drawers. Since there are advantages such as disassembling the installed interior furniture and reassembling it where it is needed, the furniture is also changing to fit the sense of the new generation.

Such interior furniture is a fixed space in a building, for example, a vertical frame (or post), a horizontal frame, and a shelf on one side including the corner of the room are assembled with each other with fixing bolts to install clothes hangers or storage cabinets for hanging clothes. By fixing a storage shelf on which you can place small items or tools, you can directly adjust the arrangement position of the interior furniture according to the consumer's preference.

As a prior art for assembling such interior furniture, it is composed of a vertical frame, a horizontal frame, and a shelf, and a plurality of the vertical frames are fixedly installed between the indoor ceiling and the floor of a building with a fixing bracket, and between these vertical frames Interior furniture has been developed so that it can be used as a hanger, storage cabinet, or shelf by fixing a horizontal frame and shelf to the wall.

This type of interior furniture is significantly improved compared to the existing wooden wardrobes and storage cabinets, but it provides convenience and ease of use. There were several problems in the method of installing a vertical frame in the interior of a building.

That is, the indoor ceiling of a building is usually fixed with square wood in a grid shape on the slab surface, and finished with veneer or gypsum board on these square wood, so that the indoor ceiling maintains a constant space with the slab surface.

Therefore, in the conventional interior furniture, in order to fix the vertical frame to the indoor ceiling and floor of the building, the upper part of the vertical frame is fixed to the indoor ceiling veneer or gypsum board of the building. After a period of time, the function of the vertical frame will be lost.

To improve this, if you want to fix the vertical frame to the slab surface of the indoor ceiling of the building, you need to fix the vertical frame on the slab surface by drilling a veneer or gypsum board in the ceiling. However, the workability of disassembling and assembling is remarkably poor, and there are disadvantages such as blocking the perforated hole in the ceiling when changing or moving the installation location of the interior furniture. There is a problem in that it cannot be provided, and there is a limitation that it cannot be easily assembled and disassembled, especially for unskilled people.
