<Configuration>
As shown in FIG. 1A, the light reflection marker 0100 of this embodiment includes a metal base 0110 having a three-dimensional outer shape having upper, lower and side peripheral surfaces, and a peripheral surface positioned on the side peripheral surface of the metal base 0110. It has a reflecting portion 0150 and a top-side reflecting portion 0160 located on the top surface of the metal substrate 0110 .

In this embodiment, as shown in half in FIG. 1B, the metal substrate 0110 has a truncated cone shape with an upper annular wall 0112 extending upwardly and radially from the periphery of the upper surface 0111. there is Similarly, the metal base 0110 has a lower annular wall 0114 extending downwardly and radially from the periphery of the lower surface 0113 .

Then, as shown in FIG. 1C, a strip-shaped light reflecting sheet 0120 is wrapped around and attached to the side peripheral surface 0115 that is continuous in the circumferential direction between the upper annular wall 0112 and the lower annular wall 0114, thereby forming the peripheral surface side reflecting portion 0150. to form This light reflecting sheet 0120 is fixed to the side peripheral surface 0115 of the metal substrate 0110 by the adhesive surface if it has an adhesive surface, or via an adhesive if it does not have an adhesive surface. be done.

At this time, the strip-shaped light reflecting sheet 0120 is placed on the side peripheral surface 0115 between the upper annular wall 0112 and the lower annular wall 0114 without gaps or overlaps, and is flush with the height of both annular walls 0112 and 0114. I'm trying to fit it in. That is, the light reflecting sheet 0120 is cut so that the width and length of the light reflecting sheet 0120 are substantially the same as the width and length of the side peripheral surface 0115 of the metal substrate 0110, and the thickness of the light reflecting sheet 0120 and the height of the two annular walls 0112 and 0114 are cut. By making the thicknesses substantially the same, the light reflection sheet 0120 is made difficult to peel off, and the positioning of the light reflection sheet 0120 is facilitated when the light reflection sheet 0120 is wound and fixed.

On the other hand, a disk-shaped light reflecting sheet 0122 is stacked on the upper surface 0111 surrounded by the upper annular wall 0112 with spacers 0121 interposed therebetween, thereby forming the upper surface side reflecting portion 0160 . This disk-shaped light reflecting sheet 0122 is also attached to the upper surface 0111 of the metal substrate 0110 by the adhesive surface if it has an adhesive surface, or via an adhesive if it does not have an adhesive surface. Fixed.

Also in this upper surface side reflection part 0160, a disk-shaped light reflection sheet 0122 is fitted on the upper surface 0111 surrounded by the upper annular wall 0112 without gaps or overlaps and flush with the height of the upper annular wall 0112. I'm trying to get in. That is, the light reflecting sheet 0122 is cut so that the radius of the upper surface 0111 of the metal substrate 0110 is substantially the same, and the thickness of the light reflecting sheet 0122 (including the thickness of the spacer 0121) and the height of the upper annular wall 0112 are equal to each other. are made substantially the same, the light reflecting sheet 0122 is made difficult to peel off, and positioning when fixing the light reflecting sheet 0122 is facilitated.

The light reflecting sheets 0120 and 0122 disposed on the entire surface other than the lower surface 0113, which is the mounting surface of the metal substrate 0110 having the shape of a truncated cone, are used to prevent the light from flashlights carried by pedestrians and headlights of bicycles and automobiles. It is desirable to use a retroreflective sheet for the light reflecting sheet that reflects the light of .

When this retroreflective sheet is used for the light reflective sheets 0120 and 0122, light from flashlights and bicycle/car headlights is reflected straight toward pedestrians and bicycle/car drivers. and the driver can clearly see the reflected light in a bright state. Suitable retroreflective sheets include, for example, prism-type high-brightness reflective sheets manufactured by 3M (trade names: 3930 White, 3931 Yellow, 3932 Red, 3935 Blue, etc.).

As the material used for the metal substrate 0110, metals such as aluminum, stainless steel, and nickel alloys can be used. The material is not particularly limited as long as it has the weather resistance and impact resistance required for the marker.

In this embodiment, the metal substrate 0110 is formed by cutting aluminum into a solid truncated cone shape. A light reflective marker 0100 can be provided. Here, in the metal substrate 0110 of this embodiment, as described above, the lower annular wall 0114 is provided on the lower surface 0113 side, that is, the lower surface 0113 is recessed. Even if there is, for example, even if there is some unevenness on the upper surface of the curb B between the sidewalk and the roadway, it is possible to install it substantially flat.

Further, a large-diameter screw receiving hole 0116 and a small-diameter screw hole 0117 are continuously provided on the axial center of the metal base 0110 having a solid structure. By screwing the male screw portion 0131 on the side, the screw 0130 is integrated with the metal base 0110 while the screw head 0132 is accommodated in the large-diameter screw accommodation hole 0116 .

In this case, the screw 0130 has a stopper 0133 for retaining at its tip, and the screw 0130 integrated with the metal base 0110 is embedded in the curb B between the sidewalk and the roadway, for example, a marker receiver 0140. The metal substrate 0110 is fixed to the curb B by inserting it into the fixing hole 0141 and locking the stopper 0133 . For the marker receiver 0140 to be embedded in the curb B, it is desirable to use a synthetic resin or hard rubber having some degree of elasticity.
In place of the stopper 0133, the screw 0130 has a coarse external threaded portion at its tip, and this externally threaded portion is screwed into the fixing hole 0141 of the marker receiver 0140 in the same manner as a wood screw. It may be fixed.

Furthermore, when the metal substrate 0110 of the light reflection marker 0100 has a solid structure as in this embodiment, the recessed lower surface 0113 of the metal substrate 0110 and the upper surface of the curb B are attached with double-sided tape.

Reflected light can be visually recognized even in the installed state.

In addition, since the light reflection marker 0100 of this embodiment has a truncated cone shape, the peripheral surface side reflection portion 0150 located on the side peripheral surface of the metal substrate 0110 forms an inclined surface, which can be used for flashlights, bicycles, etc. Since the light from the automobile headlight is reflected obliquely upward, pedestrians and drivers can clearly see the reflected light in a bright state.

Furthermore, since the surface of the light reflection marker 0100 of this embodiment is protected by a transparent glass coating, the light reflection sheets 0120 and 0122 of the peripheral surface side reflection portion 0150 and the upper surface side reflection portion 0160 are protected from scratches and water damage. and protected from dust.

In this embodiment, the case where the light reflection marker 0100 has a truncated cone shape is shown, but the present invention is not limited to this. The overall shape of the light-reflecting marker may be any shape as long as it can warn pedestrians and car drivers with reflected light regardless of which direction they are approaching. , a cylindrical shape, a truncated pyramid shape, a prismatic shape, or the like.

In this embodiment, the light reflecting sheet 0122 in the upper reflecting portion 0160 of the light reflecting marker 0100 having a truncated cone shape has a flat surface. For this reason, it is desirable to slightly bulge or sharpen the center portion of the top-side reflecting portion 0160 .

Furthermore, in this embodiment, aluminum is cut to form the solid truncated cone-shaped metal substrate 0110, but a metal plate is pressed to form the hollow truncated cone-shaped metal substrate. You may make it
