Description

Block type art implements

The present invention relates to block-type art tools, and more specifically, to block-type art tools that are easy to assemble and disassemble and enable various expressions.

Pixel art is one of the types of art for children's play, development, or as a hobby.

Pixel art is a method of expressing images by preparing means that act as one pixel in several colors and arranging the means of appropriate colors in appropriate positions. Means that act as pixels include, for example, thread, blocks, beads, etc.

This type of pixel art has the advantage of being easily accessible and enjoyable for anyone to use, as it can easily express images by arranging means that act as pixels.

However, because the shape of the means that serve as pixels is constant, there are bound to be limitations to expression. And if you reduce the size of the means that act as pixels to enable more detailed expression, there is a problem that it is not easy to modify the position of the block once it is fixed, especially if the means that act as pixels are made of blocks. .

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

Figure 1 shows a perspective view of the block-type art tool (1) according to the present invention, and Figure 2 shows a longitudinal cross-sectional view of the block-type art tool (1) according to the present invention.

The block art tool (1) according to the present invention basically includes a block frame (10) and a plurality of color blocks (20).

In the block art tool (1) according to the present invention, the color blocks (20) are made up of various colors, so it is possible to create an image by placing the color blocks (20) of each color at an appropriate position on the block frame (10).

The overall shape of the block frame 10 is plate-shaped. In Figure 1, the case where the block frame 10 is made of a square plate shape is shown, but it can also be made of a circular or hexagonal shape. A plurality of coupling protrusions 11 are provided on the upper surface of the block frame 10. The coupling protrusions 11 are arranged at regular intervals in the row and column directions and may be formed on one side of the block frame 10. The coupling protrusion 11 serves to fix the color block 20 to the block frame 10.

The color block 20 has an overall shape of a hexahedron. The cross-sectional size of the color block is formed to match the size of the space occupied by one coupling protrusion (11) in the block frame (10). A coupling groove 21 is provided on the lower surface of the color block 20 so that the coupling protrusion 11 of the block frame 10 can be inserted. The color block 20 can be fixed to the block frame 10 by inserting the coupling groove 21 of the color block 20 into the coupling protrusion 11 of the block frame 10.

At the center of each coupling protrusion 11, a through hole 11a is formed in the direction penetrating the block frame 10, that is, in the vertical direction.

In order to make the image created by the block art tool (1) according to the present invention more detailed, when the spacing between the coupling protrusions (11) and the size of the color blocks (20) are made small, the block frame (10) is combined. After inserting the color block 20 into the protrusion 11, it may be difficult to correct the position of the color block 20. In particular, it is not easy to remove the color block 20 surrounded by other color blocks 20 from the block frame 10.

The through hole 11a allows the color block 20 fixed to the block frame 10 to be easily removed and the position of the color block 20 to be easily modified. That is, the color block 20 can be easily removed from the block frame 10 by inserting a sharp object such as an awl or pin into the through hole 11a at the bottom of the block frame 10 and pushing out the color block 20. .

The color block 20 may have various sizes. That is, one color block 20 can be formed to have a various number of coupling grooves 21. In this case, the coupling groove 21 of one color block 20 is formed to be the same as the spacing between the coupling protrusions 11 of the block frame 10 and can be inserted into the block frame 10.

The coupling protrusion 11 has an overall shape of a square cross section, and may be provided with coupling auxiliary grooves 11b on each of the four sides. The coupling auxiliary groove (11b) has a long rectangular shape on the cross-section of the coupling protrusion (11) and is formed throughout the height direction (up and down direction) of the coupling protrusion (11).

When the coupling protrusion 11 is provided with a coupling auxiliary groove 11b, the block-type art tool 1 according to the present invention may further include a plurality of quarter color blocks 30. Figure 3a shows a perspective and cross-sectional view of the quarter color block 30.

The quarter color block 30 has a hexahedral shape whose cross section is one quarter the size of the color block 20. The height of the quarter color block (30) is the same as the height of the color block (20), but the cross section is formed to be one quarter of the size of the color block (20), so if four quarter color blocks (30) are placed, the color block (20) It occupies the same area as the other one.

The quarter color block 30 is provided with a second coupling groove 31 at one corner of the lower surface. One corner of the coupling protrusion 11 may be inserted into the second coupling groove 31. That is, the space occupied by one color block 20 can be filled by inserting the quarter color blocks 30 into each corner of the coupling protrusion 11.

By using these quarter color blocks (30), it is possible to express images created using the block-type art tool (1) of the present invention in more detail.

The second coupling groove 31 has a square cross-sectional overall shape, and a coupling auxiliary protrusion 31a is formed on the inner surface facing the coupling auxiliary groove 11b, and is provided with a coupling auxiliary groove 11b. It may engage with the coupling protrusion (11). The quarter color block 30 having this second coupling groove 31 is coupled to the coupling protrusion 11 in a shape that pinches the corners of the coupling protrusion 11, so it can be firmly fixed to the coupling protrusion 11. . The coupling auxiliary protrusion 31a may be formed only at the top of the second coupling groove 31 in the height direction as shown in (a) of FIG. 3, but as shown in (c) of FIG. 2 It is also possible to form the entire coupling groove 31 in the height direction.

As shown in Figure 3b, the block-type art tool (1) according to the present invention may further include a bipartite color block (35) formed in one-half the size of the color block (20). The bipartite color block 35, like the quarter color block 30, may be provided with a second coupling groove 31 and a coupling auxiliary protrusion (31a).

A block detachment groove 22 may be formed at the bottom of the side of the color block 20.

The color block 20 fixed to the block frame 10 can be easily removed by inserting a sharp object such as an awl or pin into the block detachment groove 22 and lifting the color block 20.

The block detachment groove 22 may be formed on only some of the four sides of the color block, or on all four sides.

It is natural that a block detachment groove can be formed at the bottom of the side of the quarter color block (30).

The block-type art tool (1) according to the present invention may further include an adapter block (40). Figure 4 shows an explanatory diagram of the adapter block 40.

The adapter block 40 serves to connect the coupling protrusion 11 of the block frame 10 and the color block 20. That is, the adapter block 40 can be fitted into the coupling protrusion 11 of the block frame 10, and the color block 20 can be fitted into the adapter block 40.

When the color block (20) is coupled to the block frame (10) using the adapter block (40), the color block (20) is attached to the block frame (10) compared to the case where the color block (20) is directly coupled to the block frame (10). ) becomes more protruding from the Accordingly, it is possible to form an image three-dimensionally using the block-type art tool (1) of the present invention, making it possible to further diversify the method of expressing the image.

More specifically, the adapter block 40 has a cross-section of the main body of the same shape as the cross-section of the engaging protrusion 11, and a fixing protrusion 41 is formed on the lower surface. The fixing protrusion 41 is shaped to engage with the engaging protrusion 11 so that it can be inserted into the through hole 11a of the engaging protrusion 11. The adapter block 40 can be fixed to the block frame 10 by inserting the fixing protrusion 41 into the through hole 11a of the coupling protrusion 11, and the color block 20 is attached to the adapter block 40. The color block 20 can be fixed to the adapter block 40 by fitting the coupling groove 21.

The block-type art tool (1) according to the present invention may further include an auxiliary adapter block (45). Figure 5 shows an explanatory diagram of the auxiliary adapter block 45.

The auxiliary adapter block 45 is formed in the shape of a short square tube with a length shorter than the coupling protrusion 11 of the block frame 10. At the center of the auxiliary adapter block 45, a coupling hole 46 is formed in a shape that engages the coupling protrusion 11. The coupling hole 46 is formed entirely in the longitudinal direction of the auxiliary adapter block 45.

This auxiliary adapter block 45 serves to adjust the height of the color block 20 when the adapter block 40 is used. That is, as shown in (c) of FIG. 5, the adapter block 40 and the auxiliary adapter block 45 are coupled to the coupling protrusion 11, and then the color block 20 is coupled to the adapter block 40. If so, the length at which the color block 20 is coupled to the adapter block 40 becomes shorter due to the height of the auxiliary adapter block 45, so compared to the case without the auxiliary adapter block 45, the block frame 10 is used as a reference. It can be combined at a higher position.

The block-type art tool (1) according to the present invention may further include a second adapter block (50). FIG. 6 shows an explanatory diagram of the second adapter block 50.

The second adapter block 50 serves to connect the coupling protrusion 11 and the adapter block 40. That is, the second adapter block 50, the adapter block 40, and the color block 20 are sequentially coupled to the coupling protrusion 11 of the block frame 10, so that the color block 20 is a second adapter block ( It can be connected to the block frame (10) through the 50) and adapter block (40).

The second adapter block 50 allows the image created by the block-type art tool 1 of the present invention to be formed in a more three-dimensional manner.

More specifically, the second adapter block 50 may be formed so that its lower end surrounds the coupling protrusion 11 and its upper end has a cross section identical to that of the coupling protrusion 11. Not only the adapter block 40 can be coupled to this second adapter block 50, but also the color block 20 can be coupled thereto. In addition, the second adapter blocks 50 can be combined, allowing the image created by the block-type art tool 1 of the present invention to be made more three-dimensional.

The second adapter block 50 can be used together with the auxiliary adapter block 45, as shown in (d) of FIG. 6. That is, the combined length of the color block 20 with respect to the second adapter block 50 can be adjusted by coupling the auxiliary adapter block 45 to the top of the second adapter block 50.

A second through hole 51 penetrating the second adapter block 50 in the vertical direction may be formed at the center of the cross section of the second adapter block 50. A pin, etc. passing through the through hole (11a) of the block frame (10) passes through the second through hole (51), so that the color block (20) or adapter can be easily separated from the second adapter block (50). .

A block detachment groove may also be formed at the bottom of the side of the second adapter block 50.

A plurality of frame coupling protrusions 12 may be formed on the lower surface of the block frame 10. Figure 7 shows a perspective view of the block frame 10 in an overturned state.

The frame coupling protrusions 12 are arranged at intervals in the row and column directions. The frame coupling protrusion 12 may be formed regardless of the position of the coupling protrusion 11. These frame coupling protrusions 12 can be used to connect different coupling frames.
