DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0016] FIG. 1 is a front view of a signpost 1 according to an embodiment of the present invention, and FIG. 2 is an exploded cross-sectional view showing the components of the signpost 1. As shown in FIGS. 1 and 2, the signpost 1 includes a base 10 and a columnar column portion 20 extending from the base 10. The column portion 20 has flexibility such that it can be deformed by an external force in a restorable manner. A mirror layer 30 is provided on at least a part of a surface 21 of the column portion 20. The light reflectance of the surface 31 of the mirror layer 30 is higher than the light reflectance of the surface 21 of the column portion 20. Note that in FIG. 2, the cross section of the inside of the column portion 20 is omitted, and the cross section of the surface 21 of the column portion 20 is shown. The configuration of the signpost 1 will be specifically described below.

[0017] As shown in Figs. 1 and 2, the column portion 20 extends in a columnar shape in the vertical direction, and has an upper end 22, which is the upper end, and a lower end 23, which is the lower end. The upper end 22 forms, for example, a surface facing the upper side, and the lower end 23 forms, for example, a surface facing the lower side. The column portion 20 is columnar, for example, as shown in Fig. 1, and has a cylindrical or approximately cylindrical side surface 24. The column portion 20 may be hollow or solid. The column portion 20 is supported by the base portion 10 at the lower end portion 20a, which is a portion near the lower end 23, and extends upward from the base portion 10. The shape of the column portion 20 is not limited to a columnar shape, but may be a prismatic column shape, and the cross-sectional shape of the column portion 20 is not limited to a circle, but may be a polygon such as a triangle or a rectangle, or may be another shape.

[0018] As described above, the column 20 has flexibility that allows it to be deformed by an external force in a restorable manner. Specifically, for example, it has flexibility that allows it to be deformed even when it is subjected to an impact of a person touching it. In addition, the column 20 has the restorability to return to its original shape or approximately its original shape when the external force is removed after it has been deformed by the external force. The column 20 is made of an elastic material having the above-mentioned flexibility, such as polyurethane. Note that the column 20 may be made of other elastic materials such as other resins and rubbers having the above-mentioned flexibility.

[0019] The upper end 22, the lower end 23, and the side surface 24 of the column part 20 are the surface 21 of the column part 20, and as described above, the mirror layer 30 is provided on at least a part of the surface 21. As shown in FIG. 2, the mirror layer 30 spreads in a layer or film shape and has an exposed surface 31. The mirror layer 30 is formed by spreading a substance such as paint. As shown in FIG. 2, in this example, the mirror layer 30 is formed on the entire or almost entire surface 21 of the column part 20. The mirror layer 30 is provided on at least a part of the surface 21 of the column part 20, and the range of the surface 21 of the column part 20 on which the mirror layer 30 is provided is not limited to a specific range. For example, the mirror layer 30 may be formed only on the upper end 22 and the side surface 24, may be formed only on the upper end 22, may be formed only on the side surface 24, may be formed only on a part of each of the upper end 22 and the side surface 24, or may be formed only on a part of the upper end 22 or the side surface 24. However, the mirror layer 30 is provided on the exposed portion of the sign post 1.

[0020] As described above, the light reflectance of the surface 31 of the mirror layer 30 is higher than the light reflectance of the surface 21 of the column section 20. In other words, the mirror layer 30 is a member on the surface 21 of the column section 20 that is formed so that the light reflectance of the surface 31 is higher than the light reflectance of the surface 21 of the column section 20. The mirror layer 30 is formed, for example, by mirror processing or mirror finishing of a member formed on the surface 21 of the column section 20. Also, the mirror layer 30 is formed, for example, by spreading a predetermined fluid on the surface 21 of the column section 20.

[0021] The light reflectance of the surface 31 of the mirror layer 30 is, for example, 50% or more. The light reflectance of the surface 31 of the mirror layer 31 is, for example, 70% or more. The light reflectance of the surface 31 of the mirror layer 30 is, for example, the reflectance of light having a wavelength of 400 nm or more and 800 nm or less, that is, visible light.

[0022] FIG. 3 is a diagram for specifically explaining the light reflectance of the surface 31 of the mirror layer 30. FIG. 3 shows a graph showing the relationship between the wavelength of light and the reflectance, and also shows the spectral reflectance curves of aluminum, silver, gold, iron, and copper. As shown in FIG. 3, the relationship between the wavelength of light and the reflectance of polyurethane is considered to have a relationship in the range shown in region R. Therefore, the surface 31 of the mirror layer 30 has a higher light reflectance than the region R for light having a wavelength of 400 nm or more and 800 nm or less. As a specific example, as described above, the reflectance of the surface 31 of the mirror layer 30 for light having a wavelength of 400 nm or more and 800 nm or less is 50% or more, as shown in region P1. As a specific example, as described above, the reflectance of the surface 31 of the mirror layer 30 for light having a wavelength of 400 nm or more and 800 nm or less is 70% or more, as shown in region P2. Such a surface 31 of the mirror layer 30 has a glossier surface than the surface of polyurethane.

[0023] Specifically, for example, the surface 31 of the mirror layer 30 is a mirror surface such as the surface of aluminum or silver. That is, the surface 31 of the mirror layer 30 has a uniformly high reflectance for all light having a wavelength of 400 nm or more and 800 nm or less, similar to the spectral reflectance curves of aluminum and silver. The surface 31 of the mirror layer 30 may be a glossy surface that emits a color. That is, the reflectance of the surface 31 of the mirror layer 30 for light having a wavelength in a specific region (color) may be increased, and the reflectance of the surface 31 of the mirror layer 30 for light having a wavelength in the other region (color) may be decreased, so that the surface 31 of the mirror layer 30 has a glossy surface that emits a specific color. Specifically, for example, the surface 31 of the mirror layer 30 has a glossy surface that emits a specific color such as blue, green, yellow, red, or purple. The above-mentioned form of the surface 31 of the mirror layer 30 is an example, and the form of the surface 31 of the mirror layer 30 is not limited to these.

[0024] As shown in Figs. 1 and 2, the base 10 is a portion that functions as a base for the sign pole 1, and spreads outward in the radial direction from the pole portion 20. The radial direction is a direction perpendicular to the up-down direction in which the sign pole 1 extends. The base 10 has, for example, a disk-like shape, and has a bottom surface 11 as a grounding surface and a support portion 12 formed at a position facing away from the bottom surface 11. The support portion 12 is a portion to which the lower end portion 20a of the pole portion 20 is attached and supports the pole portion 20. In addition, the support portion 12 is configured so that the pole portion 20 can be removed from the support portion 12. The support portion 12 has, for example, a recess 13 that accommodates the lower end portion 20a of the pole portion 20, as shown in Fig. 2. The recess 13 is recessed downward, and is shaped so that, for example, the lower end portion 20a of the pole portion 20 is press-fitted into it. Specifically, the recess 13 has, for example, a cylindrical side surface 13a and a bottom surface 13b. The side surface 13a is adapted to come into contact with a side surface 24 of the column portion 20 housed in the recess 13. The bottom surface 13b is adapted to come into contact with a lower end 23 of the column portion 20 housed in the recess 13. The shape of the base 10 is not limited to a disk shape, and may be another shape.

[0025] As shown in FIG. 2, the base 10 is provided with a weight 14. The base 10 is, for example, solid, and the weight 14 is embedded inside the base 10. The weight 14 may be exposed from the surface of the base 10. The base 10 may be provided with one weight 14 or with multiple weights 14. The base 10 is made of, for example, polyurethane. The material of the base 10 may be other materials. The weight 14 is made of, for example, metal. The material of the base 10 may be other materials.

[0026] The mirror layer 30 may also be provided on at least a part of the surface 15 of the base 10. The surface 15 of the base 10 is a surface that forms the outer shape of the base 15, and includes the bottom surface 11 and the recess 13. For example, as shown in FIG. 2, the mirror layer 30 is formed on the surface 15 of the base 10 except for the bottom surface 11 and the recess 13. The mirror layer 30 is provided on at least a part of the surface 15 of the base 10, and the area of ​​the surface 15 of the base 10 on which the mirror layer 30 is provided is not limited to a specific area. However, the mirror layer 30 is provided on the part exposed on the signpost 1.

[0027] The base 10 and the post 20 of the sign pole 1 are members similar to a road sign pole such as a Post Cone (registered trademark).

[0028] The sign pole 1 has the above-mentioned configuration, with the pole section 20 supported by the base section 10 and extending upward from the base section 10. The sign pole 1 is used by placing it on an installation surface such as the ground. When the sign pole 1 is in use, the bottom surface 11 of the base section 10 is in contact with the installation surface, and the pole section 20 stands on the installation surface. As the base section 10 is provided with a weight 14, the sign pole 1 can stand stably on the installation surface.

[0029] The sign pole 1 has a mirror layer 30 on the surface 21 of the pole portion 20 and the surface 15 of the base portion 10. The light reflectance of the surface 31 of the mirror layer 30 is higher than that of the surface 21 of the pole portion 20. Therefore, the mirror layer 30 gives a person who sees the sign pole 1 the impression that the portion on which the mirror layer 30 is formed is made of a hard material. This impression of a hard material can deter a person from intentionally striking a portion of the sign pole 1, such as the pole portion 20. In particular, when the light reflectance of the surface 31 of the mirror layer 30 is high, for example, when the light reflectance of the surface 31 of the mirror layer 30 is 50% or more or 70% or more, the mirror layer 30 gives a person who sees the sign pole 1 the impression that the portion on which the mirror layer 30 is formed is made of a harder material, such as metal, and has a great effect of deterring a person from intentionally striking the sign pole 1. Furthermore, when the mirror layer 30 is formed on the entire exposed portion of the surface 21 of the pillar portion 20, or when the mirror layer 30 is formed on the entire exposed portion of each of the surface 21 of the pillar portion 20 and the surface 15 of the base portion 10, the mirror layer 30 gives a person who sees the sign post 1 the impression that the entire pillar portion 20 or the entire sign post 1 is made of a harder material such as metal, which has a significant effect of deterring people from intentionally striking the sign post 1. This makes it possible to prevent people from sitting on the sign post 1 or striking it and intentionally damaging it.

[0030] In addition, since the base 10 and the pillar 20 are separable, the base 10 and the pillar 20 can be separated from each other and stored separately. In this way, the sign pole 1 can reduce the storage space.

[0031] As described above, the sign pole 1 according to the embodiment of the present invention can prevent intentional damage.

[0032] An engagement portion for engaging the base 10 and the column 20 with each other may be provided between the recess 13 of the base 10 and the lower end 20a of the column 20. The engagement portion is, for example, a protrusion or recess formed in the recess 13 of the base 10 and a recess or protrusion formed in the lower end 20a of the column 20. When the column 20 is housed in the recess 13 of the base 10, the engagement portion is engaged with the base 10 and the column 20, thereby making it possible to firmly fix the base 10 and the column 20 together.

[0033] The base 10 may also be formed with a screw portion extending downward from the bottom surface 11. The screw portion has a screw thread. In this case, the signpost 1 can be fixed to the installation surface by fastening the screw portion to a screw hole formed in the installation surface.

[0034] The pillar portion 20 may be fixed to the base portion 10. For example, the pillar portion 20 may be accommodated in the recess 13 of the base portion 10 and fixed to the base portion 10. The fixing is performed by, for example, a fixing member such as a bolt, an adhesive, or the like. The fixing method is not limited to this.
