Description

[Detailed explanation of the idea] The present invention relates to a blackboard type display device.

In other words, a blackboard-style display is created by attaching characters, figures, symbols, etc. to the board using magnetic adsorption. They can be easily arranged in an orderly manner, can be easily installed and removed, are safe to touch and do not come off easily even if other objects come into contact with them, can be used for all kinds of purposes for display, and can be easily installed and removed. It is provided that the structure is easy to manufacture and can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a perspective view of the whole. An aluminum edge frame 1 is fitted around the 4 peripheries of a flat iron board A with four corners so as to be higher than the surface of the board A. A large number of horizontal ridges 2 are formed by press molding at regular intervals in the vertical direction, and each ridge 2 has a rounded cross section, and the entire surface of the board A is painted black.

B indicates a display body, and each display body can be made into a plate with characters, figures, symbols, etc. as shown in Figures 1 and 3, or with the letter 3 attached as shown in Figure 5. The magnetic surface 4 is integrally formed by applying butadiene and a synthetic rubber solution mixed with magnetic iron powder to the back side of the display body B, and the height of each display body B is equal to that of the board A.
It is formed so that it fits within the interval between the upper and lower raised stripes 2, 2, and the thickness is lower than the height of the raised strips 2, and each display body B has a color that is symmetrically different from the black color of board A. Construct by coloring.

In addition, when forming the display body B such as characters, it is also possible to form a large number of characters etc. by cutting out a wide plate whose back surface is the magnetic surface 4.

Therefore, as shown in FIG.
Just align the display B with the board A side between the magnetic surfaces 4 and 4.
The display members B can be attached one after another by moving them from side to side.

Therefore, the display bodies B can be combined and attached or detached to be used as a blackboard type display device.

In this state, even if your hand touches board A, it will be safe because the raised stripes 2 are rounded, and even if another object tries to touch the board A, it will come into contact with the raised strips 2, so the raised stripes will be safe. Display body B lower than 2 is prevented from being dropped.

Note that the display properties are clear because the board A is black and the display body B has different color retention.

In this way, the present invention forms a large number of raised stripes with rounded cross sections in the horizontal direction at regular intervals in the vertical direction on the surface of the iron plate board to which the edge frame is fitted around the periphery of the upper and lower raised strips. A magnetic surface that resists the adhesion of magnetic iron powder is integrally formed on the back side of the display body for letters, figures, symbols, etc., which has a height that falls within the interval of , and a thickness that is lower than the height of the raised stripes.
Since the display body is attached and configured to be attached to the board in a detachable manner, the display body can be attached to the board using magnetic adhesion, making it possible to create a blackboard-style display. The display can be easily arranged in an orderly manner according to the raised stripes, the display can be easily attached or removed by adsorption on the magnetic surface, and the raised stripes are rounded so it is safe to touch. Since the display body is lower than the raised stripes, the display body is prevented from coming into contact with the raised stripes even if other objects come into contact with it, and this display device can be used for all kinds of display purposes. , it has the advantage of having a simple structure, being easily manufactured, and being suitably implemented.

Claims (1)

[Scope of utility model registration request] 4. On the surface of the iron plate board with the edge frame fitted around it, there are a number of raised stripes with rounded cross-sections in the horizontal direction at regular intervals in the vertical direction, and the height falls within the interval between the upper and lower raised strips. A board with characters that has a thickness that is lower than the height of the raised stripes, a magnetic surface that is resistant to magnetic iron powder adhesion is integrally formed on the back of the display material such as letters, figures, symbols, etc., and the display material is attached to the board. A blackboard type display device characterized in that it is installed and configured so that it can be attached and detached.
