Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a display panel which can be freely written and erased for posting, and in particular, a display panel where writing and erasing tools are not limited.

[0002]

2. Description of the Related Art For example, in a company, a hotel, a restaurant, a civil engineering work place, etc., when posting various kinds of information, an erasable display panel equipped with dedicated writing and erasing tools is sometimes used. As a concrete example, a meeting schedule by department,
Examples include a schedule for each person, cooking materials in the refrigerator, and a list of work schedules.

Conventionally, the display board is made of, for example, a slate plate, which is a base, coated with white paint so that the written characters are easy to see. In addition, characters and ruled lines may be printed on the surface of the display board to assist with writing. The display board is provided with a dedicated writing / erasing tool according to the paint applied to the surface thereof. Then, one or several places are fixed to the wall surface with a hook or the like and used.

[0004]

[Problems to be Solved] However, in the conventional display panel, the writing and erasing tools dedicated to the display panel cannot be used for writing on the display panel. This is inconvenient for the user. For example, when used by a plurality of people, the special writing and erasing tools may be lost. Also,
When substituting with writing and erasing tools in each person's hand, it is difficult to completely erase the letters, depending on the type of writing tool.

Further, when an organic solvent is used to remove the above-mentioned contamination, there is a possibility that the paint or the like on the surface of the display board may peel off. In view of such conventional problems, the present invention does not limit the type of writing instrument and the erasing means,
It aims to provide a display panel that can be easily filled and erased.

[0006]

The present invention is a display board comprising an inorganic transparent layer which can be written and erased on an inorganic board.

A colored base layer is preferably provided between the inorganic board and the inorganic transparent layer. As a result, it is possible to make a display panel in which the surface of the display panel has any color such as white, green, and blue. For example, white is a display panel for dates and green is a display for a list of items stored in the refrigerator. It can be used as a board or the like.

As the material of the inorganic board, it is preferable to use a metal plate such as an iron plate or an aluminum plate, or a ceramic plate. This improves the strength. Further, when the above-mentioned iron plate is used, it is easy to attach the magnet hook to the back surface of the display board. Also, the aluminum plate is lightweight and does not easily corrode. The ceramic plate may be a sintered plate of alumina, mullite, or the like. Further, it is preferable that these ceramic plates do not contain asbestos. This is to prevent asbestos pollution.

As a material for the inorganic transparent layer and the colored base layer, soda glass is preferably used. That is, first, when soda glass is used for the outermost inorganic transparent layer,
Pencils, ballpoint pens, magic ink, and whether they are oil-based or water-based can be easily written on the surface. Moreover, these entries can be erased very easily by using a tissue paper or a piece of cloth that is slightly moistened. When soda glass is used for the inorganic transparent layer and the colored base layer, the inorganic transparent layer can be firmly bonded to the inorganic board.

Further, soda glass has high transparency. Therefore, the color of the colored base layer does not change due to the inorganic transparent layer and directly comes into contact with the eyes, so that a display board having a variety of beautiful colors can be obtained. Further, the base inorganic board can be protected by the inorganic transparent layer and the colored base layer. In addition, soda glass has the advantages of low cost, low melting point, and easy processing. In addition, soda glass also exhibits high wear resistance against writing and erasing.

The colored base layer is preferably colored by dispersing a pigment in soda glass. It is preferable that the display board has a hook on its back surface for attaching to a mating member. The hooking device is provided, for example, on the back surface of the display panel in an annular shape that goes around its periphery. Magnets, double-sided tape, etc. are preferable as the material of the latch. This allows the display panel to be easily and surely attached to the side wall of a large refrigerator, the wall of an office, or the like.

Further, it is preferable that the display board has a rotary attachment such as a hinge for rotatably attaching to the mating material, and has a cushion material on the back surface. As the cushion material, sponge is preferable. It is preferable that the rotary attachment is attached to, for example, the upper portion of the display panel so that the user can pull up the surface of the display panel.

In this case, it is easy for the user to write characters on the display panel in the horizontal state. Further, even if the person who fills in the hand comes off the display panel after completing the entry, the cushion material on the back surface of the display panel can prevent strong contact between the display panel and the other material. Therefore, the display panel is not damaged.

[0014]

[Operations and Effects] The present invention is designed to fill in an inorganic board,
An erasable inorganic transparent layer is provided. The inorganic transparent layer side is the surface on which characters and the like are written. Therefore, it can be used regardless of the type of writing instruments such as pencils, ballpoint pens, and magic ink. Further, it can be easily erased by a tissue paper impregnated with a little water, a piece of cloth, etc., and any erasing tool and means may be used. Therefore, according to the present invention, it is possible to provide a display panel that allows easy writing and erasing without limiting the type of writing instrument and the erasing means.
