Description

Prefabricated desk and chair {SECTIONAL TABLE AND CHAIR}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembled desk and a chair, and more particularly, to a prefabricated desk and chair capable of minimizing the number of parts constituting a desk and a chair, allowing a user to easily assemble them, .

In general, desks and chairs are furniture used in schools, academies or homes, and they are firmly connected to the metal frame by means of fastening means such as screws and are delivered according to the order of the consumer.

However, the desk and the chair have a disadvantage in that a large amount of labor is required for assembling the furniture, and a large amount of the desk and chairs are loaded on the cargo truck as the assembly is completed.

Recently, a lot of furniture such as a desk or a chair has been put on the market where a user assembles a part constituting a desk or a chair directly on the spot.

Open No. 10-2012-0040332 has been proposed as an example of such a prefabricated furniture. This relates to a rest chair for a golf driving range, and is advantageous in that it can be assembled on the spot and can be easily replaced even if it is partially broken.

However, since the chair of Reference 1 has to be fastened with a large number of fixing bolts in combination with the hangers and the billboards, the table boards, the table supports, the cup supports, etc., assembly work is troublesome and takes a lot of time, There is a problem that it is not suitable for directly assembling the chair.

On the other hand, as an example of another prefabricated furniture, Registration No. 20-0427977 has been proposed. The present invention relates to a prefabricated chair, and a prefabricated chair is proposed in which an entire original plate is partitioned and each boundary portion of the partitioned portion is folded and assembled to form a seat portion and a back portion so as to sit comfortably in various events or outdoor activities .

The seat 100 includes a seat plate 110 and a backrest 120. The seat plate 110 and the backrest 120 are integrally formed by folding and assembling a single plate of paper or synthetic resin, It is possible to use it for use activity but it is structurally unstable and it is difficult to use for a long period of time in a state where it is assembled in a home or office.
