Abstract

Traditionally, after a game ended, all the pieces and other objects had to be removed from the game board, and either a new game had to be started, the pieces had to be rearranged, or the pieces had to be temporarily placed elsewhere. Also, even if magnets were used to hold the pieces in place, they were only resting there, and there was a risk that the pieces and other objects would move if the board was moved. [Solution] Two identical game boards are made, with pieces that can be attached and detached. One board is used for playing, and the other for storage. After each game, the playing board and the storage board are swapped. When starting the next game, the pieces are removed from the storage board (old playing board) and placed on the new playing board (old storage board). In Go and Othello, the pieces are placed while the game continues, and in Shogi, all the removed pieces are placed back to their initial positions before the next game can begin. After the last game, the pieces do not need to be removed from the playing board; they can be stored with the pieces still attached. Since the pieces are stuck to the playing board, they will not move or fall even if the board is moved or turned upside down.

Description

Technical Field

[0001] The present invention relates to a go board, a reversi board, and a shogi board with removable stones, using two game boards 1.

Background Art

[0002] Conventionally, go boards, reversi boards, and shogi boards (hereinafter referred to as game boards) place stones or pieces (hereinafter referred to as stones, etc.) on a single game board or adsorb them to the board with magnets. However, for these game boards, after the game ends, if all the stones, etc. 5 are not removed and the board is left empty, neither the next game nor the end of the game could be carried out. Also, except during a break, it is normal to play until the end of one game. Stopping the game during the game and leaving the stones, etc. 5 placed and having a replay the next day or later is almost impossible because it is difficult to store the state as it is. Therefore, when arranging the go or shogi scores in the newspaper that comes every day, leaving the stones on the board from the previous day and arranging the scores for the next day was practically difficult except by arranging and saving the scores on a personal computer.

[0007] [Patent Document 5] Publicly available practical edition, Showa 56-19299 [Overview of the project] [Problems that the invention aims to solve]

[0008] Until now, after a game ended, the stones used would remain on the game board and had to be removed before the next game could begin. Also, after all the games were finished, if the stones remained on the game board, it was impossible to put the game board away, so it was necessary to remove the stones and store them in a storage container, which was a troublesome process. Furthermore, in addition to the game board and the stones, a storage container for the removed stones was always required. Moreover, conventional game boards, except for those made of plastic or paper, were thick and heavy, and the stones were also thick and bulky, making them difficult to carry around. [Means for solving the problem]

[0009] This invention involves creating two game boards 1, one as the playing board 2 and the other as the storage board 3 for the stones 5, thus eliminating the need for a separate storage container for the stones 5. Both game boards 1 have the same playing board surface 4 printed on them, with letters and symbols around the edges. The dimensions of each game board 1 are rectangles approximately 100-500 mm in length and width, with a thickness of 0.1-10 mm. Additionally, storage spaces for the stones 5 are provided around the edges of each playing board surface 4. Note that the breakdown of "stones, etc." includes, in addition to stone 5, white stone number 13, black stone number 14, in-game marker 18, and progress marker 24.

[0010] The entire front surface of the game board 1 and the stones 5, etc., come in two types: a. or b. a. Detachable fabric type: The game board 1 uses a detachable fabric (e.g., toy cloth), and the stones 5 etc. use a detachable fabric (a fabric that can be attached to and detached from the aforementioned detachable fabric, e.g., hook-type Velcro®) to allow attachment and detachment to the detachable fabric. A flat board (wood, paper, plastic, or metal) is glued to the entire back surface of the detachable fabric of the game board 1. b. Plastic type: The game board 1 and pieces 5, etc., are made of plastic and are designed to be detachable. (Detachable processing includes detachable adhesive processing, interlocking grooves, etc.)

[0011] On the game board 2, a "game in progress" mark 18 (a small red disc, etc.) is attached to the "game in progress" display area 8 at the top left of the game board 1 to indicate that it is game board 2. Also, the storage board 3 for stones, etc. 5 is for storing stones, etc. 5 used in the game.

[0012] When starting a new game, the game board 1, which was previously designated as storage board 3, is converted into new game board 2 by attaching the game mark 18 that was on game board 2 in the previous game. Game board 1, which was previously game board 2, is then used as new storage board 3. Game board 2 and storage board 3 are used alternately for each game. For games, the stones and other items 5 attached to new storage board 3 are removed for Go and Othello, and all items for Shogi are removed before being attached to new game board 2 for the game. [Effects of the Invention]

[0013] After a game, the stones and other items (5, etc.) on game board 2 do not need to be removed. They can be left attached and used as a new storage board 3 for the next game, or stored with the stones still attached. This eliminates the need for the previous methods of (a) removing all the stones and other items (5, etc.) from game board 2 before starting a new game, and (b) removing all the stones and other items (5, etc.) and placing them in a storage container when finishing a game.

[0014] Since stones 5 etc. are attached to the game board 1, even if the game board 1 is moved or turned upside down, stones 5 etc. do not move or fall. Also, there are two types of the game board 1 and stones 5 etc. a. Detachable cloth type: The game board 1 is a thin board with the back of the detachable cloth attached, and stones 5 etc. are made of detachable cloth that can be attached to and detached from the game board 1. b. Plastic type: The game board 1 and stones 5 etc. are made of plastic, and they are detachably processed so that both can be detached.

[0015] Since it can be stored with stones 5 etc. attached to the game board 1, there are serial go and serial shogi that take more than 10 days per game in the game column of newspapers etc. Every day, while copying stones 5 along the score sheet onto the battle board 2, one can enjoy the progress of the game.

Embodiments for Carrying Out the Invention

[0017] Hereinafter, the basic concept will be explained with reference to FIGS. 1 and 2, and FIGS. 3 to 8 will sequentially detail the embodiments thereof.

[0018] Figure 1 shows the game board 2 as an explanatory diagram, in the state just before the start of a game, with the stones 5 and other pieces not yet attached to the game board 1. The surface of the game board 1 has the game board surface 4 printed on it, the column number 6 above the game board surface 4, the row number 7 to the left of the game board surface 4, and a rectangle indicating the "in progress" display area 8 in the upper left corner of the game board 1. Positioning marks 17 for replacement stones, etc., are printed on the top and left sides of the game board 1, and a removable "in progress" mark 18 is attached to the "in progress" display area 8. Furthermore, the game board 1 is made of two types, a. or b., depending on the material. a. Detachable fabric type: The entire front surface of the game board 1 is covered with a detachable fabric (e.g., toy cloth), and the entire back surface of the fabric is glued to the board underneath. b. Plastic type: Game board 1 is a plastic board with a removable surface so that stones 5 and other pieces can be attached and detached.

[0019] Figure 2 shows the storage board 3 for stones 5 and other items as an explanatory diagram. The shape and markings of the game board 1 are exactly the same as those of the game board 2 in Figure 1. The storage board 3, like the game board 2, comes in two types, a. and b., depending on the material. The storage board 3 still has the stones 5 and other items from previous games stuck to the game board 4. The stones 5 and other items consist of white stones 20, black stones 21, and a game in progress mark 18 (attached to the game board 2 in Figure 1), and are made in two types, a. and b., so that they can be attached to and detached from the game board 1. a. Detachable fabric type: Stone 5, etc., is made of a detachable fabric (e.g., hook-type Velcro®) that can be attached to and detached from the aforementioned detachable fabric. b. Plastic type: The stones 5 and other pieces are made of plastic and are designed to be easily attached to and detached from the game board 1.

[0020] Examples 1 to 3 will be described sequentially below based on Figures 3 to 8. [Examples]

[0021] Go example: Figures 3 and 4 show the usage status of the playing board 2 and storage board 3 during a Go game.

[0022] The game board 2 in Figure 3 is constructed as follows: a Go board surface 4 is in the center of the game board 1, vertical ruled lines with column numbers 6 are above the Go board surface 4, horizontal ruled lines with row numbers 7 are to the left of the Go board surface 4, and in the upper section of the game board 1, from left to right, there is a section 8 indicating that the game is in progress, a section 9 for stones captured by Black, and a section 13 for White stones. In the lower section of the game board 1, from left to right, there is a section 14 for Black stones, and to its right, a section 10 for stones captured by White. Furthermore, in the left section of the game board 1, there is a section 11 for replenishing White stones, and in the right section of the game board 1, there is a section 12 for replenishing Black stones. In Figure 3, a "game in progress" mark 18 is attached to the "game in progress" display section 8 to indicate that it is the game board 2.

[0023] On board 4 of the game board 2 in Figure 3, the white stones 20 and black stones 21 currently in play are attached. In addition, numbered stones are placed in the white stone number column 13 and the black stone number column 14 to indicate the following from newspaper or other game records: a. which day the game was unfinished, b. whether it was white stone 20 or black stone 21, and c. where the game ended (Example of use: In Figure 3, the black stone numbered 1 is placed at position 3-6).

[0024] The stone storage board 3 in Figure 4 is exactly the same shape as the game board 2 in Figure 3. The stones 5 from the previous game remain on the board surface 4 in the center of the board. These remaining stones 5 are being peeled off and used as stones 5 on the game board 2 in Figure 3.

[0025] The above game board 1 and stones 5, etc., have been processed as follows for each of the two types, a. and b.: a. Detachable fabric type: The entire surface of the game board 1 is covered with a detachable fabric, and the entire back surface of the fabric is attached to the board underneath with adhesive. The stones 5 and other pieces are made of detachable fabric and are designed to be attached to and detached from the game board 1. b. Plastic type: The game board 1 and stones 5 are made of plastic, and their surfaces are designed to be detachable, allowing them to be attached and removed from each other. [Examples]

[0026] Othello example: Figures 5 and 6 show the usage of the playing board 2 and the Othello stone storage board 3 during an Othello game.

[0027] Figure 5 shows the game board 2 used during a match. Column number 6 is located above the Othello board 4, row number 7 is on the left side of the Othello board 4, a "In Progress" indicator 8 is located at the left end of the upper section of the game board 1, with a white stone replenishment section 11 to its right, and a black stone replenishment section 12 in the left vertical section of the game board 1. An "In Progress" mark 18 is attached to the "In Progress" indicator 8. In the case of Othello, the stones 5 are white on one side and black on the other, and the backs of the white stones 20 and black stones 21 are glued together to form a single stone.

[0028] Figure 6 shows the Othello piece storage board 3, where piece 5 from the previous game remains in the same position on the board. The empty spaces are because piece 5 used in Figure 5 has been removed.

[0029] The game board 1 and stones 5 mentioned above have the following modifications applied to each of the two types, a. and b.. a. Detachable fabric type: The entire surface of the game board 1 is covered with a detachable fabric, and the entire back surface of the fabric is glued to the board underneath. The stones 5 and other pieces are made of detachable fabric, with the front side being white and the back side being black, and the backs of each are glued together so that they can be attached to and detached from the game board 1. b. Plastic type: The game board 1 and the stones 5, which are made of a white-sided, black-sided laminated plastic, are made of plastic, and the surface is designed to be detachable, allowing the game board 1 and stones 5 to be attached and detached. [Examples]

[0030] Shogi example: Figures 7 and 8 show the current state of the playing board 2 and the piece storage board 3 during a shogi match.

[0031] Figure 7 shows Shogi board 2, with the game board 4 in the center, column number 6 above game board 4, row number 7 to the right of game board 4, a "In Progress" display area 8 at the left end of the upper section of game board 1, a "Pieces Captured by Black" area 9 to its right (the left side of game board 1 can also be used as "Pieces Captured by Black" area 9), and a "Pieces Captured by White" area 10 at the bottom of game board 1 (the right side of the game board can also be used as "Pieces Captured by White" area 10). And since this is game board 2, a "In Progress" mark 18 is attached to the "In Progress" display area 8.

[0032] The game board 1 and the 25 pieces come in two types: a. and b. Game board 1 is designed to be detachable from the pieces 25 as follows: a. Detachable fabric type: A board with the detachable fabric facing outwards and the entire back surface attached. b. Plastic type: A plastic sheet with a removable surface facing outwards.

[0033] Piece 25 is designed to be detachable from the game board 1 as follows: a. Detachable fabric type: A piece made by gluing the backs of two detachable fabrics together. b. Plastic type: Two plastic pieces bonded together with their backs facing each other, with a detachable front and back. In this way, the pieces 25 can be attached to and detached from the game board 1 using either the front or back side. The front side of the pieces 25 has the black characters of a shogi piece printed on it, and the back side of the pieces 25 has the red characters of a shogi piece printed on it.

[0034] Two donut-shaped discs of progress marker 24 are required. Each progress marker 24 is made by gluing the backs of two discs together so that the side that attaches to the game board 1 and piece 25 faces outwards. There are two types of progress marker 24: a. and b. a. Detachable fabric type: The front of the game board 1 and the pieces 25 are made of detachable fabric, while the back is made of non-detachable fabric, allowing them to be attached and detached. b. Plastic type: The front and back surfaces of the progress markers 24 are processed to be detachable, allowing them to be attached and detached to the game board 1 and the pieces 25.

[0035] Progress marker 24 has two intended uses: A. and B. a. To check the progress the next day, place the piece on top of the piece that was played that day in the newspaper's game record. I. To indicate which day's newspaper the game record is from, the Arabic numerals for days up to the 9th day are placed above the Arabic numerals in the upper column of Shogi board 4, and for days 10 and beyond, they are placed above the Chinese numerals in the right column of Shogi board 4. (For example, placing it above "three" would represent the 13th day by adding 10. However, placing it above "ten" would simply represent the 10th day.) In Figure 7, the game on the third day ended with the move 1-6 pawn being left unplayed.

[0036] The shape of piece 25 should be such that its orientation is clearly visible; the front of piece 25 should be rounded or pointed, while the back of piece 25 should be flat and straight. (The straight part of piece 25 should be facing the player.)

[0037] The shogi piece storage board 3 in Figure 8 has the same shape as in Figure 7, and the lines, symbols, and letters are exactly the same. The only difference is that storage board 3 does not have the "in-progress" mark 18. Currently, a game is in progress, so all shogi pieces 25, the "in-progress" mark 18, and the progress mark 24 have been moved to the shogi game board 2, and therefore nothing is marked on storage board 3. [Industrial applicability]

[0038] The newly designed game board 1 is wider than existing game boards, yet thin, lightweight, and portable. It also allows for the attachment and removal of pieces (such as stones 5) to the game board 1, and even storage with the pieces still attached. Because the pieces are stuck, they remain in place even when the game board 1 is moved or turned upside down, allowing for play even on a moving train. Furthermore, players can follow the game records published daily in newspapers by using their fingers to place the pieces on the game board 2, enjoying the game's progress. Additionally, the thin design of game board 1 allows for easy storage in narrow spaces between furniture, making it convenient to retrieve and store. It is expected that many people will use this advantageous game board 1, opening up a new customer base and significantly contributing to the industry. It also has a wide range of potential applications, including Western chess and diamond games. [Explanation of Symbols]

Claims

1. This invention involves creating two game boards, one for playing and the other for storing stones, thus eliminating the need for a separate storage container for stones. The two game boards have identical text and symbols printed on the playing surface and its surrounding area. One game board is used as the playing surface and the other as the storage surface for stones. When playing again after a match, the old storage board is used as the new playing surface and the old playing surface is used as the new storage surface, eliminating the need to remove the stones after a match and store them in a storage container. Furthermore, storage spaces for attaching stones are provided around the periphery of each board, eliminating the need for a separate storage container. The stones and game boards are processed to be detachable from each other, and either type a. or b. is used for the entire surface of the game board and the stones. a. Detachable fabric type: A game board is used in which the entire back surface of the detachable fabric is attached, and stones, etc., are made of detachable fabric, making them possible to attach to and detach from the game board. b. Plastic type: The game board and pieces, etc., are made of plastic, and the surface is treated to allow for easy attachment and detachment of both.

2. As a tool for playing Go, two game boards are made, one used as the playing board and the other as a Go stone storage board. The roles are switched after each game, and when the next game is played, the Go stones are removed from the old playing board and placed on the new playing board. The surface of each game board is printed with the game board and other elements (letters, symbols, lines), and each game board also has a Go stone storage space, eliminating the need for a Go stone container. To clearly indicate that it is a playing board, a "in-progress" mark is attached to the "in-progress" display area. The Go stones and the surfaces of the two game boards are of one of two types, a. or b., that allow the Go stones to be attached and detached. a. Detachable fabric type: This type uses a game board with a detachable fabric attached to the entire back surface, and the white and black stones are made of detachable fabric that can be attached to the aforementioned fabric, allowing them to be attached to and detached from the game board. b. Plastic type: The game board and go stones are made of plastic, and the surfaces of the game board and go stones are designed to be detachable. Additionally, by preparing white and black stones numbered from 1 to 10, it is possible to indicate: a. which day the game was played, b. where the game was played, and c. whether the stone is white or black.

3. The Othello game uses two game boards: one for playing and the other for storing the Othello pieces. The roles are switched after each game, and for the next game, the pieces are removed from the old game board and placed on the new game board. The surface of each game board has the game board and other elements (letters, symbols, lines) printed on it, and there is a space for storing spare pieces, eliminating the need for a separate storage container. To clearly indicate that it is a game board, a "in-progress" mark is attached to the "in-progress" display area, and the surfaces of the two game boards use either type a. or b. to allow for the attachment and detachment of pieces and other elements. a. Detachable fabric type: For the game board, a board with a removable fabric attached to the entire back surface is used, and for the stones, a removable fabric that can be attached to the game board is used, and the white stones and black stones are glued together with the backs facing outwards. b. Plastic type: The game board and stones are made of plastic, and the front surface of the game board and the outer surface of the stones (where the backs of the white and black stones are bonded together) are processed to allow for easy attachment and detachment of the two.

4. As a tool for playing shogi, two game boards are used: one as the playing board and the other as the piece storage board. The roles are switched for each game. When a game is played, the pieces are removed from the old playing board (which was used in the previous game) and all the pieces are placed on the new playing board to start the game. This eliminates the need to remove, move, and rearrange the pieces as was done in the past. It also eliminates the need to remove and store the pieces after all the games are finished, as the pieces can be stored while still attached to the board. The surface of each game board is printed with the playing board and other elements (letters, symbols, lines). Each game board has a space for storing captured pieces, eliminating the need for a piece stand or other storage device. The front of the pieces is printed in black, and the back is printed in red with the characters from King to Pawn. The playing board has a "in progress" mark in the display area to indicate that a game is in progress. The game board surface uses either type a. or b. to allow for the attachment and detachment of pieces. a. Detachable fabric type: The game board uses a board with the entire back surface of the detachable fabric attached to it, and the pieces are made by attaching the backs of two detachable fabrics together so that they can be attached to the game board using either the front or back side. b. Plastic type: The game board and pieces are made of plastic, and each has a detachable design that allows them to be easily attached and detached. Additionally, two perforated circular progress markers are needed that can be attached to and detached from the game board and pieces, and these markers serve two purposes. I. Place it on the number on or to the right of the board, indicating which day the game was unfinished according to the newspaper's game record. b. Where did the piece that was about to be played end up being placed on top of the piece that was about to be played?
