Folding desk {DESK HAVING HINGE}

The present invention relates to a folding desk, and more specifically, can be used to expand both sides or rear space of the top plate as needed, as well as to prevent concentration of both sides and rear of the top plate to increase concentration in study or office work It relates to a folding desk having a.

In general, a desk refers to an image used when sitting, reading a book, writing or watching office work. A desk with a bookcase at one side, a desk with a bookshelf at the front, and both sides and the front except for the front are blocked. The desk is known.

The desk most widely used in the prior art is composed of a reinforcement thickening plate which reinforces both sides by interconnecting the rear side of both support side plates and both support side plates serving as legs standing vertically on the lower sides of the upper plate and the upper plate.

Therefore, the desk composed of the upper plate, both the support side plate and the reinforcement thick plate as described above is most widely used for home or office use as it has sufficient durability.

However, a conventional desk composed of a top plate, both supporting side plates, and a reinforcement thick plate as described above is easy to study or work with books or documents on top of the top plate, but it is not possible to increase the space of the top plate as necessary. Had a problem.

In addition, the front and both sides of the top plate was open, there was a problem that the concentration is reduced when studying or office work.

In addition, as the front and rear width of the desk is usually narrow, when the large monitor is placed on the desk, the distance between the monitor and the user is short and there is a problem in that the eyes are severely tired.

Accordingly, the present invention has been made to solve the above problems,

An object of the present invention is to provide a folding desk that can be used to expand the space on both sides of the top plate as needed, as well as to prevent both sides and the rear of the top plate to increase concentration in study or office work.

Another object of the present invention is to provide a folding desk for extending the rear of the top plate so that a large monitor constituting a computer can be installed at a distance from a user.

The present invention for achieving the above object, the main body consisting of a reinforcing thick plate that interconnects both the support side plate and both support side plate vertically erected on both sides of the upper plate and the lower plate, so as to protrude both sides and rear of the upper plate Formed extension protrusions, both side plates connected to both sides of the extension protrusions so as to be rotated vertically or horizontally through side hinge connectors, and rear plates connected to the rear extension protrusions so as to be able to rotate vertically or horizontally through rear hinge connectors; Connecting means for interconnecting and fixing both side plates and the rear plate in a state in which both side plates and the rear plate are erected vertically on both sides of the upper surface and the rear of the upper plate, and optionally when the side plates maintain the horizontal state, The supporting leg and the rear plate selectively in a horizontal state when maintaining the horizontal state A rear leg portion supporting the rear plate, and the connecting means includes at least one tab groove formed at both ends of the rear plate, and at least one assembly hole formed at a rear side of the side plates corresponding to the tab groove in the horizontal direction, and the assembling. It characterized in that it comprises a plurality of fixing bolts that are penetrated by the hole to the tab groove.
