Rubber magnet go stone, go board, and manufacturing method

Abstract

To solve the problem that portability is also not considered much in invention and an idea regarding a go stone.SOLUTION: Since a go stone and a go board are attracted mutually by using the go stone manufactured by a method for setting a sheet formed by using a polymer material, such as rubber and plastic for a magnetic powder, namely a rubber magnet sheet to a thickness of approximately 3 mm, and performing molding by blanking it to a circular shape with an appropriate size, and a go board made of a steel rubber sheet, a portable go set can be provided readily, thus greatly contributing to the spread of the game of go.SELECTED DRAWING: Figure 3

Description

[Technical field]

[0001] The present invention relates to a go stone and a go board specialized for portability, and a method for manufacturing the same. [Background technology]

[0002] Go stones are tools used in the game of Go and Rengo, and are disc-shaped and come in two colors, black and white. A set of black and white stones is placed in a container called a go bowl or go utensil. When playing Go, they are sometimes simply called "stones." A go board is one of the tools used in Go, and is the board on which the Go stones are placed. The top surface of the board has straight lines drawn vertically and horizontally, and these lines intersect at right angles.

[0003] Black go stones are made from black stones, with Nachi black stones being considered masterpieces. White go stones are generally made from cut and polished clam shells, but clam go stones are very expensive, and in the Meiji period, go stones made from ceramic or bamboo also existed. In the Taisho period, glass go stones were prototyped, but at the time they were ordinary glass rather than hardened glass, and were brittle and prone to breaking. Later, products made from plastic or hard glass became available, and cheaper equipment also appeared. Meanwhile, go boards are often made from wood from large trees that are hundreds of years old, such as kaya, katsura, ginkgo, cypress, Japanese cypress, agathis, and spruce.

[0004] In recent years, lightweight portable go stones and boards as well as magnetic go sets have appeared, making it possible to enjoy a casual game of go on the go, and have greatly contributed to the popularity of the game. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2016-67863 A [Patent Document 2] Utility model registration No. 3202785 Summary of the Invention [Problem to be solved by the invention]

[0006] However, as described in Patent Documents 1 and 2, inventions and ideas relating to Go stones do not take portability into consideration, such as stones that have steel sheets attached or stones that have iron powder mixed into the raw materials. [Means for solving the problem]

[0007] In order to solve the above problems, the invention of claim 1 is a go stone characterized in that magnetic powder is bonded and molded using a polymer material.

[0008] The invention of claim 3 is a go board in sheet form, 3 mm thick, 36.4 mm long and 34.0 mm wide, characterized in that magnetic powder is bonded and molded using a polymer material.

[0009] The invention of claim 4 is a method for manufacturing black go stones, characterized in that magnetic powder is formed into a sheet of 3 mm thickness using a polymer material, and then punched out into a circle with a diameter of 17.76 mm. Effect of the Invention

[0010] According to the present invention, it is possible to produce a lightweight Go set in which the stones do not shift even with slight vibrations due to the magnetic powder contained in the stones and the iron powder contained in the Go board. The Go set according to the present invention can be easily carried around, which will greatly contribute to the spread of Go. [Brief description of the drawings]

[Diagram 2] 1A is a plan view and FIG. 1B is a side view of a Go stone 2 according to an embodiment of the present invention. [Diagram 3] FIG. 2 is a flow chart of a manufacturing process of Go stones according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. The following embodiment is an example for explaining the present invention, and is not intended to limit the present invention to the embodiment. Furthermore, the present invention can be modified in various ways without departing from the gist of the invention. Furthermore, the same components in each drawing are denoted by the same reference numerals as much as possible, and duplicated explanations are omitted.

[0013] <Embodiment 1> First, we will explain the materials that make up the black go stone 1 of embodiment 1. The main component of the go stone 1 is a polymer material 21 that contains magnetic powder 11. Figure 1 shows a) a plan view and b) a side view of the go stone 1 according to the embodiment of the present invention.

[0014] The polymer material 21 is, for example, rubber or plastic, and in the first embodiment, a so-called rubber magnet sheet is formed by bonding magnetic powder with the polymer material and forming it into a sheet, which is then punched out into a circle. The thickness H1 of the rubber magnet sheet is not particularly specified, but considering the size of the hand used to play Go and portability, it is preferable that it is 3 mm. The diameter D1 of the Go stone 1 is also not particularly specified, but considering portability, it is preferable that it is 17.76 mm.

[0015] It is preferable that one Go set contains 301 black Go stones 1 of the first embodiment, plus two extra stones as spares.

[0016] <Embodiment 2> First, we will explain the materials that make up the white go stone 2 of embodiment 2. Like go stone 1, go stone 2 is mainly composed of a polymer material 22 that contains magnetic powder 11. Figure 2 shows a) a plan view and b) a side view of go stone 2 according to the embodiment of the present invention.

[0017] The polymer material 22 is, for example, rubber or plastic, and in the second embodiment, the magnetic powder is bonded with a white paint and a polymer material, and the so-called rubber magnet sheet is formed into a sheet shape, which is then punched out into a circle. The thickness H2 of the rubber magnet sheet is not particularly specified, but considering the size of the hand used to play Go and portability, it is preferable that it is 3 mm. The diameter D2 of the Go stones 2 is also not particularly specified, but considering portability, it is preferable that it is 17.52 mm, which is slightly smaller than the black Go stones in the first embodiment.

[0018] It is preferable that one Go set contains 300 white Go stones 2 in the second embodiment, plus two extra stones as spares.

[0019] <Embodiment 3> Next, a description will be given of the material that constitutes the Go board 3 of the third embodiment. The Go board 3 is mainly composed of a polymer material 23 that contains iron powder 12.

[0020] The polymer material 23 is, for example, rubber or plastic, and in the third embodiment, it is a so-called steel rubber sheet, in which iron powder is bonded with the polymer material and formed into a sheet. The thickness of the steel rubber sheet is not particularly specified, but considering portability, it is preferable that it is 3 mm. The diameter of the go stones 2 is also not particularly specified, but considering portability, it is preferable that the sheet is 3 mm thick, 36.4 mm long, and 34.0 mm wide.

[0021] Ruled lines are printed on the surface of the go board 3. There is no particular rule regarding the number of ruled lines, but it is preferable that the size be 19×19.

[0022] <Manufacturing method> Next, an example of a method for manufacturing Go stones will be shown below. Fig. 3 is a flow chart showing the manufacturing process of Go stones 1 and 2 according to the embodiment of the present invention.
