BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lecture desk, and more particularly, to a lecture-integrated desk stool in which a desk and a stool are integrally folded.

Conventionally, desks and stools used for lecture rooms of schools and companies are separately separated, and thus there is inconvenience in that they are not easy to handle. Thus, a lecture desk stool integrated with a desk and a stool has been disclosed.

Thus, as an example of a lecture desk that integrates a desk and a stool, Utility Model Model No. 20-0293607, as shown in Figure 1, the leg portion 100; A seating part 110 formed in a rectangular plate shape and installed on an upper surface of the leg part 100; A backrest part 120 formed on the rear surface of the seating part 110 and supporting the back of the human body; A support part 130 formed to protrude upward on an upper surface of the seating part 110; It is formed in a plate shape and one side is coupled to the backrest portion 120, the bottom surface is coupled to the upper surface of the support portion 130, provided with a support portion 141 and the connection portion 142, one side portion is open shape Plate member 140 formed as; It is formed by connecting the support portion 130 and the plate member 140, the configuration having a coupling member 150 is reinforced by the coupling bar 151 to provide a support force to the plate member 140 It is.

By the way, the conventional integrated integrated book holder for the lecture is configured to install the plate member 140 on the upper side of the one side of the seating portion 110, so the size of the structural plate member 140 can not be limited in terms of writing simply Although it can be used as a lecture, there is a problem that it is not suitable for lectures that require a lot of books to be spread on the desk.

In addition, there is a problem in that the plate member 140 is frequently damaged because there is a limit in the supporting force for supporting the plate member 140.

In addition, since the plate member is attached to one side, there was a problem in that it is inconvenient to load the product.

Accordingly, the present invention has been made to solve the above problems, and to provide a lecture-integrated desk stool that can not only widen the width of the desk plate but also increase the bearing capacity and facilitate the transportation of the product and can be loaded and stored in a minimum space. .

The integrated bookcase for lectures according to the present invention includes a desk frame having a desk leg coupled to an upper side and a lower side reaching a ground, and a chair frame having a chair leg coupled to an upper side and a lower side reaching the ground. The lower side of the chair leg is hinged to the lower side to the desk leg is characterized in that the entire chair is accommodated folded into the lower space of the desk plate.

The back plate is hinged to an upper side of the chair leg so as to be folded toward the seat plate side.

The desk frame includes a desk support portion supporting the desk plate and a desk leg portion extending horizontally from the front end portion of the desk support portion to the ground and then horizontally extending toward the chair side. The chair supporting part supporting the seat plate, and the chair front leg extending downward from the front end of the chair supporting portion to the ground, and the chair rear leg extending downward from the rear end of the chair supporting portion to reach the ground, The lower end is hinged to the horizontal end of the desk leg.

The chair leg is provided with a latch so as to be caught by the desk leg when the chair is folded and accommodated under the desk plate.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2, in the present invention, the desk plate 20 is coupled to the upper side of the desk frame 10, the seat plate 40 is coupled to the upper side of the chair frame 30 in the horizontal direction, and the chair frame 30 is connected to the desk frame 10. The back plate 50 of the rear upper side of the stand is coupled, the chair frame 30 is hinged to the desk frame 10 by the first hinge portion 60 so that the entire chair is a lower space of the desk plate 20 It can be folded and accommodated, the back plate 50 is a structure that is hinged to the chair frame 30 by the second hinge portion 70 can be folded to the seat plate side.

The desk frame 10 extends downward from both sides of the front end portion of the desk support portion 12 and the front support portion 12, and then reaches the ground and then horizontally toward the chair side. It consists of a pair of desk legs (14, 14 ') extending to, the erected portion of the desk legs (14, 14') is coupled to the reinforcing member (16) connecting the desk legs on both sides. Foot 16 made of bedding may be coupled to the horizontal portions of the desk legs 14 and 14 '.

The chair frame 30 may include a chair support part 32 supporting the seat plate 40 and a pair of chair front legs 34 extending from both sides of the front end of the chair support part 32 to the bottom to reach the ground. 34 ') and a pair of chair rear legs 36 and 36' extending downward from both rear ends of the chair support to reach the ground, and the chair front legs 34 and 34 'and the chair rear legs ( 36, 36 ') is a structure in which the reinforcing member is coupled as necessary.

The latch 38 is coupled to an upper side of the rear legs 36 and 36 'of the chair so as to be caught by the desk legs 14 and 14' when the chair is folded and accommodated below the desk plate 20. have. The locking hole 38 is a curved plate that is concave to be in close contact with the outer circumferential surfaces of the desk legs 14 and 14 ', and preferably has a predetermined elasticity.

Both ends of the back plate 50 are hinged to the upper ends of the chair rear legs 36 and 36 'by the second hinge parts 70. At both ends of the lower plate 50, cylindrical portions 52 which are extrapolated and fixed to the rotating member described later in the second hinge portion are formed.

The first hinge portion 60 is a portion that hinges the end portions of the horizontal portions of the desk legs 14 and 14 'and the ends of the front legs 34 and 34' of the chair. The front legs 34 and 34 'are connected to the desk legs 14 and 14' so as to be folded. At this time, the front legs 34 and 34 'of the chair are coupled to the inside of the desk legs 14 and 14'. Therefore, the space between the front legs 34 and 34 'of the chair is smaller than the space between the desk legs 14 and 14'.                     

 The second hinge portion 70 has a pivoting member 72 hinged to the upper end of the rear legs 36, 36 'of the chair with a pin 74, the cylindrical portion on the upper end of the pivoting member 72 52 is extrapolated so that the back plate 50 is fixed by a fixing member such as a pin. The rotating member 72 is constrained by a restraining member (not shown) so as not to be inclined to the rear side by a predetermined angle or more, and the rotating member 72 is able to be folded only to the seat plate 40 side.

When carrying or stacking and storing the integrated monolithic bench seat for teaching according to the present invention configured as described above, as shown in FIG. 3, the back plate 50 is folded with the second hinge portion 70 as the center of rotation. 4, the front legs 34, 34 'of the chair are folded toward the desk legs 14, 14' with the first hinge 60 as the pivot center, as shown in FIG. The lower space of 20) reduces the space occupied by the chair, making it easier to store and transport on a bookcase.

When the front legs 34 and 34 'of the chair are folded and accommodated toward the desk legs 14 and 14', the engaging portion 38 is elastically deformed and the desk legs 14 and 14 ' Since it is caught on the outer circumference of the erected part, the folded chair will not move.

In addition, the present invention has a wide area of the desk plate 40, so that many lecture materials can be easily spread and the lecture can be heard, and the support force of the desk plate 20 by the desk support 12 and the desk legs 14 and 14 can be heard. Can also increase.

According to the present invention, the integrated bookshelf for lectures has the effect of not only widening the width of the desk plate, but also increasing the bearing capacity and facilitating the transportation of the product and loading and storing it in a minimum space.
