Description

[Detailed description of the device]

[0001]

[Industrial application] The present invention relates to a tool used in a game of Go and introductory instruction.

[0002]

[Prior art]

 Conventionally, there are dedicated go boards such as 19 road boards, 13 road boards, and 9 road boards. There is also known a board in which some of the lines on the board have been erased (see, for example, Japanese Utility Model Publication No. 57-32073).

[0003]

[Problems to be solved by the device]

 One of the challenges is that conventional Go tools are not considered for use in various sizes and shapes. Go usually uses a 19-road board with 19 vertical and horizontal lines, but if you can't spend a long time in the game or if you are instructing an introductory person, it is convenient to have a small board with a small number of lines. is there. Also, if the shape of the board changes, a new kind of fun will appear, which is different from the case of using a normal board in the game. In order to change the size of the board depending on the time and the case, prepare commercially available dedicated boards such as 13-road board, 9-road board, etc. in addition to the 19-road board, or use a thin paper line at the end of the large board. There is no choice but to hide and use it. In order to change the shape of the board, a special board has been devised with some lines erased, but the shape cannot be changed in various ways. Another problem is that it is difficult for beginners to understand the concept of the board edge. In the past, the edges of a board were represented by the stopping of lines. From this point onward, I used the expression of falling into a valley to explain the concept of the edge. Therefore, it seems that the conditions for surrounding the ground with stones and surrounding the other stone are different between the center and the edge of the board. Also, some beginners are confused about whether or not they can hit stones on the very end of the line, and make an illusion. The present invention was devised to solve these drawbacks, and the purpose thereof is to make one board in various sizes or shapes by changing the range of use of the board. In addition to making it available, it provides a go tool that helps beginners to understand by clarifying the edges of the board and prevents illusions and mistakes when the board is complicated.

[0004]

[Means for Solving the Problems]

 In order to achieve the above purpose, the Go tool according to the present invention is a square pole plate having a surface of the same size as one square of the board, and marking the center of each side of the board. is there. For the same purpose, a frame-shaped plate with square holes, the size of the holes is an odd multiple of the size of one square on the board, and the center of each side around the holes on the surface with holes is marked. It is also possible to use a square plate, a square column plate and a frame plate in combination, or a square board with a frame plate with the central mark removed. . Further, an adhesive substance or a magnet may be attached depending on the application.

[0005]

[Action]

 As shown in the upper left of FIG. 3, a plurality of square pole-shaped plates (1) are placed around or in the center of a normal board (4) to be used to form a boundary. At this time, as illustrated in FIG. 4, the mark (2) of the rectangular columnar plate (1) is placed so as to be aligned with the line of the normal board (4). It can be placed correctly by matching three of the four marks. The inside of this boundary is the range of use of the board. The frame-shaped plate (3) with square holes is placed on a normal board (4) as a boundary as illustrated in the lower right of FIG. 3 to serve as a boundary. At this time, as illustrated in FIG. 5, the mark (2) of the frame-shaped plate (3) is placed in line with the line of the normal board (4). You can put them correctly by combining three of the four marks. The inside of this boundary is the range of use of the board. Similarly, as shown in FIG. 8, the square columnar plate (1) is appropriately arranged inside the frame-shaped plate (3) placed on the normal board (4) to determine the range of use of the board. Fine-tune the size or change the shape of the range of use. The same applies to the case where a regular board and a frame-shaped board are used in combination with a board (5) having a frame-shaped board attached thereto and a rectangular column-shaped board (1) as shown in FIG. If necessary, an adhesive substance or a magnet is attached to the surfaces of the frame-shaped plate (3) and the quadrangular prism-shaped plate (1) in contact with the board to prevent slipping or falling.

[0006]

【Example】

 In FIG. 4, the lengths (A, B) of the sides of the rectangular columnar plate (1) are made equal to the vertical and horizontal lengths (a, b) of one square of an ordinary board. If this is not the case, the difference from the case where they are made equal shall be within 20% of the vertical and horizontal lengths of one square on a regular board. The mark (2) of the rectangular columnar plate (1) is attached to the center of the side of the rectangular columnar plate (1). The shape of this mark (2) may be a triple line, a triangle, an arrow, or a rhombus. Further, the shape of the mark (2) may be different in the vertical and horizontal directions. In FIG. 5, the lengths (C, D) of the square holes of the frame-shaped plate (3) are odd multiples of the lengths (a, b) of one square of a regular board. To be equal. If they are not equal, the difference from the case where they are equal is within 20% of the vertical and horizontal lengths of one square on a regular board. The mark (2) on the frame-shaped plate (3) is placed at the center of the vertical and horizontal sides of the square hole. The shape of this mark (2) may be a triple line, a triangle, an arrow, or a diamond. Further, the shape of the mark (2) may be different in the vertical and horizontal directions. The distance between the frame part of the board (5) with a frame and the end line on the board is equal to half the length (a, b) of one square of the board. If they are not equal, the difference shall be within 20% of the length and width of one square on the board.

[0007]

[Effect of device]

 The present invention has the following effects. In the Go tool according to claim 1, as shown in the upper left of FIG. 3, by arranging a plurality of square pole-shaped plates on a normal board, one board can be used as a board of various sizes and shapes. You can In the go tool according to the second aspect, as illustrated in the lower right of FIG. 3, the size of the board can be easily changed only by replacing the frame-shaped board. In the go tool according to claim 3, in addition to the effect of the go tool according to claim 2, the size can be finely adjusted, or the go board can be changed into a complicated shape as illustrated in FIG. In the go tool according to the fourth aspect, as shown in FIG. 9, the board can be changed into a complicated shape. In addition to the above effects, the go tool according to claim 5 or 6 can be used when the board is used vertically. When using a square column board, you can enjoy a game of Go on a complicated board that is not square, and you can also design a board in a completely new way. In addition, the concept of the edge of the board is easy to understand, which is common to all the above-mentioned Go tools. 6 and 7, the arrangement of black stones and white stones is the same. In FIG. 6, the upper left corner and the lower left corner similarly represent a state in which a black stone is surrounded by white stones. In the case of the upper left, you need to enclose all four sides of the black stone because it is the center of the board, but in the case of the lower left, you need not enclose all four sides of the black stone because it is the edge of the board. For beginners, the conditions for picking stones seem different. On the other hand, in Fig. 7, the black stone in the lower left is surrounded by white stone and a frame-shaped plate on all sides. Even though the frame-shaped plate can be used as a neutral wall to substitute for your own stone, it does not conflict with the rules of Go. In this case, the conditions for picking up stones are the same on the edge of the board and in the center. The same applies when surrounding the ground with your own stone. Furthermore, even if the shape of the board is complicated as shown in FIG. 8, there is a step at the end and the boundary is clear, so there is no illusion or mistake.
