Description

[Detailed description of the invention] (Industrial application field) This invention relates to a writing board device, and its purpose is to create a writing board, a projection screen, etc. without constricting the indoor space.
To provide a writing board device in which two types of video screens can be arbitrarily selected and easily arranged in a juxtaposed combination state.

(Prior art and its problems) Conventionally, in lectures, etc. at schools, companies, kindergartens, etc., there are cases in which people write on a writing board such as a blackboard while simultaneously showing an image on a projection film or video film. Lectures are held using a projection screen and video screen placed in front of the board.

However, in such a situation, the projection screen and video screen must be placed on top of a lectern or the like in the room, reducing the indoor space.

Furthermore, once the projection screen and video screen are removed from the room when they are not in use, they must be brought back into the room when they are to be used again, making handling inconvenient.

(Issues to be solved by the invention) In view of the above-mentioned circumstances, the industry can easily select two types of writing boards, projection screens, and video screens and arrange them side-by-side in combination without constricting the indoor space. It was hoped that a method would be created.

(Means for solving the problem) In this invention, an indoor space in front of the wall and a storage space behind the wall are divided using the wall of the room as a boundary, and two openings are provided in parallel in this wall. A part of the storage space at a substantially horizontal position of this opening is made into a perspective space from inside the room, and the storage space other than this perspective space is made into a space behind the wall. A cover plate with a colored pattern is attached to each,
Two writing boards are arranged in parallel in the perspective space behind each of the cover plates, a projection screen is arranged in the perspective space behind one of the writing plates, and a projection screen is arranged in the perspective space behind one of the writing plates. A video screen is disposed at the rear in the perspective space, each of the cover plates is movable between each opening and the space behind the wall, and each writing board is movable between the perspective space and the space behind the wall. The above problem is solved by providing a writing board device which is made movable.

(Example) An example of this invention will be described based on the drawings.

1 to 3 are diagrams illustrating a writing board device according to an embodiment of this invention, and numeral 1 in the figures indicates the writing board device.

First, the configuration of the writing board device 1 will be explained.

2 is the wall of the room, and with this wall 2 as the boundary, wall 2
An indoor space 3 in the front and a storage space 4 behind the wall 2 are divided.

The storage space 4 may be located in an adjacent room or the like.

Two openings 5, 5 are arranged in parallel in this wall 2, and through these openings 5, 5, a part of the storage space 4 at a substantially horizontal position of these openings 5, 5 can be viewed from the room through a transparent space 6. The storage space 4 other than the transparent space 6 is defined as a wall rear space 7.

Cover plates 9, 9 having the same color pattern 8 as the surface of the wall 2 are attached to the two openings 5, 5, respectively, to close the openings 5, 5.

A transparent space 6 is located behind each of the lid plates 9, 9.
Two writing boards 10, 10 are arranged side by side inside.

As the writing boards 10, 10, a blackboard, a whiteboard, etc. can be suitably used.

A perspective space 6 located behind one writing board 10
A projection screen 11 is arranged inside.

In addition to the case where the projection screen 11 is fixed in an upright position, it may be made to be tiltable from an upright position to a tilted position as shown by the broken line in FIG. 2, and when it is tilted, it is used as an overhead projection screen. This is useful in some cases.

Further, a video screen 12 is arranged in the perspective space 6 behind the other writing board 10.

Each of the lid plates 9, 9 is movable between each opening 5, 5 and the wall rear space 7, and each lid plate 9, 9 is moved from each opening 5, 5 to the wall rear space 7. By doing so, it is possible to write on the writing boards 10, 10 from the indoor space 3 through the opened openings 5, 5.

As long as each cover plate 9, 9 is supported so that it can be moved into the wall rear space 7, it may be moved in any direction from the respective openings 5, 5, up, down, left or right, but in this embodiment, a guide rail 13 is provided, Once the cover plate 9 is moved backward from the opening 5 as shown by the arrow 14, and then slid downward as shown by the arrow 15 to open the opening 5 and close the opening 5. I decided to do the opposite.

Further, each writing board 10, 10 is also movable between the transparent space 6 and the wall rear space 7, and by moving each writing board 10, 10 from the transparent space 6 to the wall rear space 7, each opening can be moved. The projection screen 11 or the video screen 12 can be seen through the parts 5, 5.

The writing boards 10, 10 may be moved from the perspective space 6 in any direction, up, down, left or right, as long as they are supported so that they can be moved in the wall rear space 7, but in this embodiment, a guide rail (not shown) is provided to move the writing boards 10,10
slide downward as shown by arrow 16 to display projection screen 11 or video screen 12.
When using the writing boards 10, 10, the opposite operation is performed.

In the figure, reference numeral 17 is a light projection opening, which projects light 18 from an overhead projector (not shown) or a slide projector, which enters through the light projection opening 17, onto the projection screen 11 or video screen 12. When not in use, it is closed with a slidable lid 19 having the same color pattern 8 as the surface of the wall 2.

FIG. 4 shows another example of this invention. In this example, tilted reflecting mirrors 21, 21 are arranged behind the see-through screen 20.
The lights 24, 24 from the overhead projector 22 or the slide projector 23 are projected onto the see-through screen 20 through the reflection of the projector 21.
4 so that the angle of incidence on the see-through screen 20 is not acute.

In addition, in this example, when using the writing board 10, the inner part of the wall 2 from the opening 5 (behind the writing board 10)
After retreating the cover plate 9, the writing plate 10 stored in the lower part of the waist below the opening 5 is raised and exposed for use.

Note that the cover plate 9 and writing plate 10 are electrically operated at hand using operation buttons 27 on an operation panel 26 provided on the lecturer table 25.

Furthermore, the operation panel 26 may also be freely accessible from the lecturer table 25.

Next, a method of using the writing board device 1 according to the above embodiment will be explained.

When only the writing plates 10, 10 are used, the cover plates 9, 9 are moved from the openings 5, 5 into the wall rear space 7, the writing plates 10, 10 are positioned in the transparent space 6, and the interior space 3 Writing is performed on the writing boards 10, 10 through the openings 5, 5.

Also, at the same time as the writing board 10, the projection screen 11
Alternatively, when using the video screen 12, one writing board 10 is moved from inside the perspective space 6 to the wall rear space 7, and the projection screen 11 or video screen 12 to be used is positioned within the perspective space 6.

Furthermore, when using the projection screen 11 and the video screen 12 at the same time, both writing boards 1
0 and 10 are moved from the perspective space 6 to the wall rear space 7, and the projection screen 11 and video screen 12 are positioned within the perspective space 6.

In addition, when neither is used, the cover plates 9, 9
The openings 5, 5 are closed with.

(Effect of the invention) This invention divides the interior space in front of the wall and the storage space behind the wall using the wall of the room as a boundary.
Through these openings, a part of the storage space at the approximately horizontal position of this opening is used as a see-through space from inside the room, and the storage space other than this see-through space is used as a space behind the wall. A cover plate having the same color pattern as the wall surface is attached to each of the two openings, and two writing plates are arranged in parallel in the transparent space behind each cover plate, one of which has a writing plate. A projection screen is arranged in the perspective space behind the board, a video screen is arranged in the perspective space behind the other writing board, and each cover plate is connected to each opening and the space behind the wall. Since the writing board device is configured such that each of the writing boards is movable between the perspective space and the wall rear space, the following effects are achieved.

In other words, a writing board and a projection screen can alternately appear in the perspective space at one opening, and a writing board and a video screen can alternately appear in the perspective space at the other opening, and these are also part of the storage space. Therefore, two of the writing board, projection screen, and video screen can be arbitrarily selected and easily arranged in a side-by-side combination without constricting the indoor space.
