DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding auxiliary table on which a drawing board is placed.

[0002]

2. Description of the Related Art Conventionally, if a drawing board made of a flat plate is placed on a flat desk as it is, it is difficult to draw a drawing. Therefore, an appropriate shaped sleeper or the like is attached to the lower side of the rear part of the drawing board. Is inclined so as to be higher from the front to the rear, so that there are the following problems.

[0003] The inclination and height of the drawing board cannot be freely adjusted. In order to change the inclination and height of the drafting board, it is necessary to prepare multi-size sleepers and the like. In particular, in schools, etc., a space is taken for storage of the sleeper or the like when the drafting board is not used.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the problems described in the prior art.
It is an object of the present invention to provide a folding auxiliary table for a drafting board, which can be freely adjusted in height and inclination and can save storage space.

[0005]

According to the folding auxiliary board for a drawing board of the present invention, adjusters for height adjustment are attached to both lower corners of a front wall and a rear wall, and left and right ends of the front wall and the rear wall are provided. To
The left and right side walls that are foldable inward from the central portion are attached to the inside so as to be able to bend inside, and the crosspiece that is foldable upward from the central portion at the lower center of the front wall and the rear wall is positioned upward. It is characterized in that it is attached so that it can be bent.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 6, a front wall 1 made of wood, plastic, corrugated ball or the like is used. Adjusters-2 for height adjustment are attached to both lower corners. The height of the front wall 1 can be adjusted by adjusting the adjuster-2.

An adjuster 2 'for height adjustment is attached to both lower corners of the rear wall 3 made of wood, plastic, corrugated ball or the like. The height of the rear wall 3 can be adjusted by adjusting the adjuster-2 '. Usually, the height of the front wall 1 is made lower than the height of the rear wall 3.

As shown in FIG. 3, a left side wall 4 made of wood, plastic, a corrugated ball or the like connects two plate members 4a and 4b with a hinge 7 or the like so as to be folded inward from the center. It has become. When folded in the direction of the arrow in FIG. 3, as shown by the dotted line, the plate members 4 a and 4 b can be folded so as to be joined together.

As shown in FIG. 4, a left side wall 5 made of wood, plastic, a corrugated ball or the like connects two plate members 5a and 5b with a hinge 7 'or the like, and can be folded inward from the center. It has become. When folded in the direction of the arrow in FIG.
As shown by the dotted lines, the plates 5a and 5b
It can be folded.

As shown in FIG. 5, the cross member 6 is formed by connecting two plate members 6a and 6b with a hinge 7 "or the like so that the plate member 6 can be folded upward from the center. When folded in the direction, as shown by the dotted lines, the plate members 6a and 6b can be folded so as to be joined.

As shown in FIG. 2, the left side wall 4 is attached to the left end of the front wall 1 and the rear wall 2 by, for example, a hinge 8 so that the left side wall 4 can be bent inward.

As shown in FIG. 2, the right side wall 5 is attached to the right ends of the front wall 1 and the rear wall 2 by, for example, a hinge 8 'so that the right side wall 5 can be bent inward.

As shown in FIG. 2, for example, a hinge 8 ″ is provided on the lower part of the center of the front wall 1 and the rear wall 2 by a hinge 8 ″.
Are mounted so that they can be bent upward.

When the left side wall 4, the right side wall 5 and the crosspiece 6 are folded, as shown in FIG.
Easy to transport, saving storage space.

In practice, when the left and right side walls 4 and 5 are expanded outward and the crosspiece 6 is expanded downward from the thick plate state shown in FIG. 6, a rectangular frame A as shown in FIG. become,
A drafting board 9 is placed on this, and an adjuster for height adjustment is provided.
By adjusting 2, 2 ', the inclination and height of the drafting board 9 are adjusted to suit the user.

The crosspiece 6 has both a function of preventing the frame A from being deformed into a diamond shape and a function of reinforcing the frame A.

[0017]

Since the present invention is configured as described above, it has the following effects. When not in use, it can be folded and stored. Since it can be folded into a plate shape, it is easy to carry and the storage space can be reduced. The crosspiece member can prevent deformation and reinforce the frame. The height and inclination of the drafting board can be adjusted freely. Easy to handle. Since the structure is simple, mass production can be performed at low cost.
