Description

Multicolored chalks for black board {Multicolored chalks for black board}

The present invention relates to chalk used for blackboards in classrooms, such as schools, and more particularly, when one chalk is divided into at least two colors and dyed to write letters in various colors when writing. Chalk has been improved to increase convenience and education.

Conventional chalk is made of solid chalk of white, blue, red, yellow and blue, respectively. The main chalk used is white, and blue, red, yellow, and blue are used for emphasis.

Since each piece of chalk is a solid color, even though you take notes with white chalk, you have to replace it with other colored chalk, and it is easy to lose it. There is a problem that can fall.

In addition, since a lot of white chalk is used and other colors of chalk are used relatively little, half of the body of the chalk is often left, which can be said to be wasteful economically.

The present invention produces a multi-colored chalk by combining different colors to the half or the end of the white chalk body that is used most often to solve the above problems.

By using multi-colored chalk that combines different colors with the original white chalk to make more than two colors, it is easy to change the color of the chalk according to the situation, providing convenience of use and reducing the frequency of lost colored chalk. The decorative effect and the economic burden of separately buying colored chalk can be reduced.

1 is a perspective view of a first embodiment of the present invention.
2 is a perspective view of a second embodiment of the present invention.
3 is a perspective view of a third embodiment of the present invention.
4 is a perspective view of a fourth embodiment of the present invention.

Specific details for carrying out the present invention are as follows.

All the chalk of the above invention is based on the most commonly used white chalk and combines the rest with colored chalk.

All drawings are a perspective view of the chalk of the present invention, Figure 1 is divided into two vertically on the basis of the long axis of the chalk white (20) and colored (10) jelly in a 5: 5 color ratio.

Colored jelly can be combined with various colors of red, yellow, and blue instead of one color.

2 is divided into two horizontally based on the long axis of the chalk to combine the white (20) jelly and the colored (10) jelly in a color ratio of 5: 5. This may be combined with various colored paints as in FIG. 1.

Figure 3 is based on the long axis of the chalk to combine vertically divided by the ratio of 7 (chalk): 3 (colored ink).

Again, colored ink can be combined in several colors.

4 is a vertical division in the ratio of 7 (chalk): 3 (coloured ink) based on the long axis of chalk, and the colored ink is further divided into two colors and combined. have.

In this figure, for example, blue (22) and red (24) chalks are combined with colored ink.

In addition, various modifications are possible within the scope of the present invention.

10: colored chalk
20: white chalk
22: blue chalk
24: red chalk
