For assembling this foldable desk, the leg plates 2 are first expanded, and, then, the front plate 3 is collapsed. Also, the engagement members 5 are turned, and then, the shelf plate 4 is turned. Thereafter, the right and left lower peripheral projections of the shelf plate 4 are coupled to the engagement members 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding desk on which a large personal computer, a large printer or the like can be placed and which can be assembled and folded in an extremely short time of about 10 seconds.

[0002]

2. Description of the Related Art Conventional folding desks are generally small in size and weak in strength because they support the total weight with four pole-shaped open / close legs, making it difficult to mount a large computer or large printer. there were. Further, when the open / close legs are folded inward, they may overlap each other, which is inconvenient (see FIG. 7 (1)). On the other hand, a fixed desk having a front plate is widely used because of its simple structure and high strength. A folding desk with a front plate is also conceivable, but it has not been put to practical use because the structure is complicated and the strength is not satisfactory. In addition, the former fixed desk has a problem that it is inconvenient for storage and transportation due to its occupied space and it is costly. Further, there is a problem that the strength is reduced when the shelf is attached to the conventional small folding desk.

[0003]

The problem to be solved by the present invention is to solve these problems in the prior art,
Provides a folding desk that can be firmly assembled in about 10 seconds without using screws, etc., and can be stored and transported in a compact shape that can be folded without overlapping the open / close legs. To do. Another object of the present invention is to provide a foldable desk which has a high strength and can carry a heavy object and has a shelf plate below the desk.

[0004]

Means for Solving the Problems The constitution of the present invention which has solved the above problems is as follows: 1) Leg plates for supporting the total weight are provided on the right and left sides of the top plate so that they can be folded inward, and the front plate is provided on the lower front side of the top plate. A plate is foldably provided on the back surface of the top plate, a shelf plate extending below the top plate is rotatably attached to the center of the back surface of the front plate, and the left and right lower peripheral projections of the shelf plate are provided inside the leg plates. An engaging member that engages with is rotatably attached to the inside of the leg plate so that the leg plate is opened vertically to the top plate, and the front plate is vertically attached to the top plate. Tilt, the engaging member is rotated so as to project inward, the shelf plate is rotated so as to extend horizontally below the top plate, and the left and right lower peripheral edge projecting portions of the shelf plate are engaged with the engaging member. Foldable desk characterized by being assembled by engaging with 2) The left and right peripheral edges of the shelf plate are projected downward. The frame member is formed of a box-shaped frame frame having a cross section, and the frame frame is a left and right lower peripheral edge projecting portion of the shelf plate, and the engaging member is a member having a U-shaped cross section with an upper surface opened in a state of projecting inward. 1) The foldable desk according to the above 1), which is pivotable by attaching a hinge to the middle of the inside of the leg plate 3) Even if the leg plates that support the total weight on the left and right of the top plate are folded inward Provided in a position where it can be stored without being folded, the front plate is provided on the lower front surface of the top plate so that it can be folded on the back surface of the top plate, and the shelf plate extending below the top plate in the center of the back surface of the front plate Is rotatably attached, and a connecting member is provided between the opened leg plate and the shelf plate to connect them to each other. The leg plate is opened vertically to the top plate, and the front plate is attached to the top plate. Tilt it vertically and extend the shelf horizontally below the top. Foldable desk characterized by being assembled by connecting the leg plate and the shelf plate with the connecting member 4) A protrusion is attached to the lower side of the leg plate, and a hole is formed in the side end surface of the front plate. The folding desk according to the above 1), 2) or 3), wherein a connecting member is provided between the leg plate that has been opened and opened and the front plate that is tilted vertically to the top plate.

[0005]

To assemble the folding desk of the present invention, the leg plates provided on the left and right of the top plate are opened vertically to the top plate, and the front plate provided on the lower front surface of the top plate is attached to the top plate. Push it down vertically. After that, the left and right engaging members attached to the inside of the leg plate are rotated so as to project inward, and the shelf plate attached to the center of the back surface of the front plate is rotated so as to extend below the top plate, The left and right lower peripheral projections are engaged with the engagement member. In a folding desk that forms a connection between the leg plate and the front plate, open the leg plate, fold the front plate vertically with respect to the top plate, fit the protrusion of the leg plate into the hole in the front plate, and place the front plate in front. Lock the pull connection. To fold the folding desk, rotate the shelf to the center of the back of the front plate and tilt it down, then rotate the left and right engaging members attached to the inside of the leg plate to the inside of the leg plate to avoid it. Fold it in the back of the board,
Fold the left and right leg plates inward. In a folding desk that forms a connection between the leg plate and the front plate, push the front plate forward of the folding desk, remove the projection of the leg plate that is fitted into the hole in the front plate,
Fold the front plate into the back of the top plate and the left and right leg plates inward.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The left and right lower peripheral edge projecting portions of the shelf of the folding desk according to the present invention can be used not only as a frame but also as another member. Above all, an integrated type in which the left and right lower peripheral projections of the shelf plate can also serve as a frame is preferable because of its simple structure. The engaging member of the folding desk according to the present invention can be appropriately adopted in a U-shape, a C-shape, a U-shape, or the like. The connecting member for connecting between the open leg plate and the shelf plate of the folding desk according to the present invention includes, in addition to the member for connecting the open leg plate and the shelf plate extending below the top plate, the open leg. There is a member that connects between the leg plate and the shelf plate that is stored in the center of the back surface of the front plate. The folding desk according to the present invention is made of a steel plate, an acrylic plate, a decorative plywood, or the like.
