TECHNICAL FIELD OF THE INVENTION
The present invention relates to a sign mainly used for a road sign or a signboard or an advertisement sign, and more particularly to a variable sign capable of changing the sign content in four ways.
[0002]
[Prior art]
Conventionally, as a variable sign of this type, a plurality of divided sign bodies having a cross-sectional shape of an isosceles triangle and two surfaces forming the equal side each being a sign surface forming a part of a predetermined sign are used. Then, a predetermined sign is made to appear by the collection of the sign faces of the divided sign bodies, and the divided sign bodies are simultaneously rotated so that one of the two sign faces of all the divided sign bodies faces forward. There is a so-called two-variable sign that allows two types of information to appear by having the sign. Also, the cross-sectional shape is a regular triangle, and each of the three surfaces is a sign surface that constitutes a part of a predetermined sign. There is a so-called three-variable sign that can use three or more divided sign bodies and make three kinds of signs appear.
[0003]
[Problems to be solved by the invention]
However, since the two-variable marker and the three-variable marker as described above each use a divided marker having a triangular cross-sectional shape, even if the interval between the divided markers is not increased, the respective marker surfaces are adjacent to each other. This structure can be rotated in a state where it is rotated, but this structure cannot be applied as it is to a so-called four-variable sign that uses a divided sign whose cross section is square. . That is, since the cross-sectional shape is a square, the length of the diagonal connecting the opposite corners is longer than the length of the sign surface, which is one side of the square. This is because the clubs cannot be rotated by hitting each other. Therefore, the structure of the conventional variable sign is generally limited to three variable types, and if it is four variable types, the work of changing the contents of the sign becomes complicated and the structure becomes complicated.
[0004]
Therefore, the present invention is to solve the above-mentioned problems, to provide a four-variable variable sign that can easily change the contents of the sign, and can show four signs with a simple structure. Is what you do.
