Abstract
Description
[Technical Field]
[0001] This invention relates to a gadget called a dice (hereinafter, these three will be collectively referred to as dice), which is used primarily for tabletop games and gambling. [Background technology]
[0002] When a conventional dice (which can be cubic, polyhedral, or other shapes) is thrown, one side touches the floor, and the other side facing the ceiling. The numbers, letters, or symbols written on the side facing the ceiling are called the result, and dice are used in a variety of tabletop games and gambling.
[0003] Traditional dice shapes include a cube or polyhedron, a regular tetrahedron, a regular hexahedron, a regular octahedron, a regular dodecahedron, a regular icosahedron, and a regular twisted heptagonal pyramid with 14 sides, which is not a square, and a regular prism like a pencil. All of these have an even number of sides, and when thrown, the character written on the side facing the ceiling is applied as the result.
[0004] The number and shape of the dice vary, but the characters written on the side that can face up after being thrown are called "eyes." On the other hand, the characters written on the side that actually faces up after being thrown are called "outlines."
[0005] The size and shape of the face that is treated as the result varies depending on the die, but after the die is rolled, the face that faces the ceiling and is opposite the face that touches the floor is roughly parallel to the face of the die that is touching the floor.
[0006] After throwing the dice, if the letters written on the upturned side are too small for the person looking at them to recognize, or if the upturned part is not a face but an edge or a point, In such cases, it is impossible for observers to determine what the top part of the dice means after throwing. Such faces, edges, and vertices are insufficient to be treated as the result of throwing the dice, and these parts are not treated as the result in the conventional way.
[0007] For this reason, even if a polygonal prism-shaped die was made using conventional dice, it was not possible to make a die with an odd number of digits. This is because when a die with an odd number of digits is rolled, the part that faces directly upward is always an edge or a vertex, and the die always has multiple digits when viewed from directly above. This means that after rolling the die, it is not possible to identify the digit that appears when viewed from above. Therefore, using conventional methods, it was not possible to make a die with an odd number of digits.
[0008] The only exception to the conventional method of rolling a dice is a regular tetrahedron die. A regular tetrahedron die has numbers, letters, symbols, etc. on each base, and after rolling a regular tetrahedron die, the numbers, letters, symbols, etc. written on the base are the same no matter which side you look at it from, so the numbers, letters, symbols, etc. written near the base are treated as the roll. Overview of the invention Problem to be solved by the invention
[0009] With traditional dice, the part facing the ceiling must have one number to produce a unique result.
[0010] To provide a method for showing only one result even if a part that could not be used as a number in the past, such as an edge, a vertex, or a face that is too small to normally write a result, faces up, and a die that can show only one result.
[0011] The purpose of this invention is to develop a tetrahedral die that allows you to see the result from above after throwing. The present invention provides a method for rolling a die with an odd number of digits, a die with a result that can be seen from above, and a method for identifying a unique result when a die with an odd number of digits is rolled, and a die with an odd number of digits.
[0012] The method according to the present invention is characterized in that after throwing the dice, the result of the throw can be determined using a part other than the conventional number roll.
[0013] The dice according to the present invention are characterized by using the method described in the above invention.
[0014] By adding a guide that points to a specific part on the face of the dice of the above invention, even if a part other than the number on the dice faces the ceiling after being thrown, the letters, symbols, numbers, etc. written on the side with the guide pointing to the part facing the ceiling can be used as if they were the number on the dice.
[0015]
[0013] The dice of the invention described above are characterized in that by forming faces on the sides, numbers, letters, symbols, etc. written on the faces can be used as if they were the results when viewed from above after the dice are thrown.
[0016]
[0013] By processing or writing around the edges of the dice of the described invention, it is possible to identify the result as one even if the dice have multiple faces or edges when viewed from above after being thrown.
[0017]
[0013] By turning the letters, numbers, symbols, etc. on the dice of the invention in a certain direction, even if the part of the dice other than the number on the dice faces the ceiling after being thrown, the letters, numbers, symbols, etc. that face the ceiling and are closest to the ceiling when viewed from above will be the upside. The invention is characterized by the fact that the written faces can be used as if they were the results of a roll.
[0018] By using the method of the present invention, it is possible to produce dice that can identify a single result after throwing an odd-numbered die, and processed regular tetrahedral dice that allow the result to be seen even when viewed from above.
[0019] Therefore, it is possible to provide dice with odd numbers and tetrahedral dice whose results can be seen from above. [Brief explanation of the drawings]
[0020] Figures 1 to 14 : 11 is a perspective view of the embodiment of the present invention, and FIG. DETAILED DESCRIPTION OF THE INVENTION
[0021] The following are examples of ways in which the present invention can be practiced:
[0022] Figure 1 shows an example of an embodiment of the present invention using a regular triangular prism. As shown in Figure 2, the sides of a regular triangular prism are formed into flat surfaces along the dotted lines to form Figure 1. Figure 3 also shows an example of an embodiment in which a regular pentagonal prism is processed in the same way.
[0023] In this way, each side edge of a regular polygonal prism with an odd number of sides is processed to create two types of faces: faces with large areas and faces with small areas.
[0024] When the above regular polygonal prism processed in this way is thrown, the face with the larger area will always face the floor and the face with the smaller area will face upwards.
[0025] A regular polygonal prism with an odd number of sides has never been used as a dice because the side that faces the ceiling after being thrown is always the side. However, if you write letters, numbers, symbols, etc. on the smaller side of a regular polygonal prism with flattened sides, the side that faces the ceiling after being thrown will be the smaller side with the letters, numbers, symbols, etc. written on it. By using the side with letters, numbers, symbols, etc. as if it were the result, a regular polygonal prism with an odd number of sides can be used as a dice.
[0026] Even if the sides are modified as shown in Figures 2 and 3, the number of faces that can be used as numbers will be the same as the number of original faces excluding the base. If the original dice is a regular triangular prism, the number of faces that can be used as numbers for the dice modified according to the invention will remain three. This is because the larger face always faces the floor after being thrown, and therefore cannot be used as a number or a result.
[0027] This also applies to decorative forms that do not affect the result when used as dice, such as forms that have been modified to add high points to each base.
[0028] This makes it possible to provide dice with an odd number of sides, which was previously impossible.
[0029] FIG. 4 shows an example of an embodiment of the present invention using a regular triangular prism as an example.
[0030] Fig. 4 shows an example of an embodiment in which a part of the side of a regular triangular prism is formed as a surface as shown by the dotted line, and Fig. 5 shows an example of an embodiment in which a part of the side of a regular pentagonal prism is formed as a surface as shown by the dotted line.
[0031] In this way, by forming a part of the side of a regular polygonal prism with an odd number of sides into a surface, even if the side of a conventional regular polygonal prism would face the ceiling after being thrown, the formed surface faces the ceiling, and the letters, numbers, symbols, etc. written on the formed surface can be known as the only result. To make it recognizable, a part of the side of a regular polygonal prism with an odd number of sides can be formed into a surface like a dotted line and used as the result.
[0032] This makes it possible to provide dice with an odd number of sides, which was previously impossible.
[0033] Fig. 6 shows an example of an embodiment of the present invention using a regular tetrahedron as an example. Fig. 6 shows a configuration in which the vertices of a regular tetrahedron are cut off as shown by the dotted lines in Fig. 7.
[0034] If you write letters, numbers, symbols, etc. on the smaller side of each face, when you roll this type of dice, what would normally be the vertex becomes a face, and the letters, numbers, symbols, etc. written on the formed face become the only known and recognizable result, so you can use this place as if it were the number rolled.
[0035] This makes it possible to provide a regular tetrahedral die that has the unique property of revealing a unique result when viewed from above, something that was previously impossible.
[0036] FIG. 8 shows an example of an embodiment of the present invention using a regular triangular prism as an example.
[0037] As shown in Figure 8, there is a method of writing various shapes of pictures on the faces of a regular polygonal prism with an odd number of sides, by surrounding or overlapping written numbers, letters, symbols, etc., to point out specific edges or vertices.
[0038] This means that after throwing a regular polygonal prism with an odd number of sides, even if the only place where an edge or vertex, rather than a face, faces the ceiling, the letters, numbers, symbols, etc. written on the side with a picture, etc., pointing to the specific edge or vertex will be known and recognizable as the only result, and this place can be used as if it were the result.
[0039] This makes it possible to provide dice with an odd number of sides, which was previously impossible.
[0040] Fig. 9 shows an example of an embodiment of the present invention using a regular pentagonal prism as an example. Fig. 10 shows an example of an embodiment of the present invention using a regular tetrahedron as an example. Fig. 11 shows Fig. 10 as seen from the back.
[0041] As shown in Figures 9, 10, and 11, guides such as arrows pointing to specific edges or vertices are added to the faces of polyhedrons that have numbers, letters, symbols, etc. written on them.
[0042] As a result, even if, after throwing the polyhedron, an edge or vertex, rather than a face, is the only place facing the ceiling, the content written on the side with the guide pointing to the specific edge or vertex will be known and recognizable as the only result, so even if the face does not face the ceiling, that location can be used as if it were the result.
[0043] FIG. 12 shows an example of an embodiment of the present invention using a regular triangular prism.
[0044] As shown in Figure 12, numbers, letters, symbols, etc. written on the faces of a regular polygonal prism with an odd number of sides are directed toward a specific face or vertex.
[0045] This means that even if the dice are not the face after being thrown but the only place where an edge or vertex faces the ceiling, the side with letters, numbers, symbols, etc. facing the ceiling will be known and recognized as the only result, and the content written on that side can be used as if it were the result.
[0046] FIG. 13 shows an example of an embodiment of the present invention using a regular triangular prism.
[0047] As shown in Figure 13, letters, numbers, symbols, etc. are written across the edges of a polygonal prism. This makes it possible to use the letters, numbers, symbols, etc. written across the vertices or edges facing the ceiling as if they were the dice roll, even if the only point facing the ceiling is an edge or vertex, rather than a face, after the dice are rolled.
[0048] FIG. 14 shows an example of an embodiment of the present invention using a regular pentagonal prism.
[0049] As shown in Figure 14, one method is to set a boundary on the surface that is in contact with the edge of the polygonal prism, and then write letters, numbers, and symbols within the boundary.
[0050] This means that even if, after throwing the dice, an edge or vertex, rather than a face, is the only place facing the ceiling, the contents of the letters, numbers, symbols, etc. written within the boundary set on the face adjacent to the edge facing the ceiling can be used as if it were the result.
