Description

The present invention relates to a fence structure that is installed at roadsides and the like and has warning elements that are visible even at night for the purpose of evacuation guidance and accident prevention, and a method for manufacturing the same, and further relates to facilities such as roads and squares that are equipped with such a fence structure.

Conventionally, caps equipped with reflective material that are attached to the ends of fence structures such as protective fences installed at roadsides and the like are known. The purpose of these caps is to use the reflective material to reflect light from the headlights of vehicles passing at night, thereby making the driver aware of the position and alerting them to prevent falls, etc. For example, Patent Document 1 discloses a cap that is attached to the ends of posts such as protective fences, with reflective tape wrapped around the periphery to accommodate light from automobile headlights coming from multiple directions (see Patent Document 1). Patent Document 2 also discloses a cap with reflective material all around (see Patent Document 2).

Japanese Utility Model Application Publication No. 3-93816 Japanese Patent Application Laid-Open No. 11-343612

Conventional caps with reflective materials disclosed in Patent Documents 1 and 2 are only intended to alert pedestrians by reflecting incident light from light sources such as automobile headlights, and are unable to alert pedestrians who do not have a light source, for example pedestrians who are not carrying any light source such as a flashlight.

In addition, the conventional caps only have a reflector on the circumference of the side of the cylindrical cap. Therefore, even if light is incident from the horizontal direction, it is considered difficult to return the reflected light to the light source and call attention to it. Furthermore, it is not possible to reflect light toward the light source when light is incident from above or diagonally above. However, especially during disasters, there is a need to reflect light toward the light source when light is incident from above or diagonally above. For example, when there is a large amount of snowfall, most of the protective fence may be buried in the snow, and the cap may only appear a few centimeters above the snow surface. In this case, for example, a person walking on the snow surface at night will be in a position to look down on the cap from above or diagonally above, so even if the person is walking while shining a flashlight on the snow surface, the reflected light cannot be seen by passersby with the conventional cap, and therefore it is not possible to call the attention of passersby.

As such, conventional caps with reflective material have the problem that they are unable to alert pedestrians who do not have a light source at night, and even if a pedestrian has a light source, they are unable to alert pedestrians who are looking down on the cap from above or diagonally above.

The present invention has been made in consideration of these problems. In other words, the problem to be solved by the present invention is to effectively warn pedestrians who do not carry a light source at night by enabling them to recognize the position of the protective fence through light from a warning member attached to the protective fence, and to effectively warn pedestrians who are in a position where they can see the warning member from above or diagonally above.

As a means for solving the above problems, the fence structure with a warning part according to the present invention is characterized in that, first, the cap is provided with a phosphorescent material, so that even passersby who do not carry a light source at night can be warned by emitting light.

＜Overview＞
The invention of this embodiment is a fence structure having a plurality of pole bodies and an attention-attracting portion.
The most significant feature of the present invention is that the attention drawing portion has a dome shape and contains a phosphorescent material.

<Configuration>
(General)
An example of the appearance of a fence structure with warning parts according to this embodiment is shown in Fig. 1. As shown in the figure, a fence structure with warning parts 0100 according to this embodiment has a plurality of pole bodies 0110 and warning parts 0120 (only one of each is given a reference number to avoid complication).

Fence structures are often called protective fences, and are intended to be installed, for example, at the roadside of a sidewalk along a river or cliff (hereinafter referred to as a "rivers, etc.") to warn pedestrians not to fall into the river, etc., or at the boundary between the roadway and the sidewalk to warn drivers not to let their vehicles enter the sidewalk and to warn pedestrians not to enter the roadway. In Figure 1, too, it is assumed that a fence structure with a warning part is installed at the roadside 0101, and that a river, etc. is immediately on the other side of the fence structure.

In this invention, a fence refers to a structure made of metal, wood, bamboo, plastic, or other materials, consisting of multiple poles lined up on the ground. This includes structures that completely cover the space between the poles, structures with horizontal boards or bars between the poles with gaps between them (as in the example in Figure 1), and structures that simply consist of multiple poles lined up.

(Pole body)
The pole body is a columnar or other column-shaped member that constitutes the fence structure with a warning part. Its material is often metal, wood, bamboo, plastic, etc., but there is no particular limitation. A plurality of pole bodies are provided in the fence structure with a warning part, and the fence structure with a warning part is constituted by arranging these plurality of pole bodies upright on the ground at regular intervals, for example, at equal intervals of 2 meters.

A warning unit is attached to the upper end of each pole body. There are no particular limitations on the method of attachment, but one suitable method is to press the warning unit into the cavity at the upper end of the pole body (hereinafter sometimes referred to as a "hollow pole"), as described below. In this case, it is therefore desirable that at least the upper end of the pole body be cylindrical with a cavity.

There are no particular limitations on the dimensions of the pole body, but it is desirable that the length be such that the tip will not be buried and will be visible to passersby in the event of a disaster such as flooding or heavy snowfall, while still taking into consideration the scenery, etc. Specific dimensions will be appropriately designed based on disaster predictions for the installation location, etc. The one shown in Figure 1 is intended for a pole body with a diameter of about 10 to 15 centimeters and a height of about 1 to 1.5 meters above the road surface, but this is merely one example.

(Caution section: General)
The attention-calling part is a dome-shaped dome part provided at the top of the pole body, and at least a part of the dome part contains a phosphorescent material. The reason why the attention-calling part is a dome-shaped dome part is to make the light emission visible from above or from an obliquely upward direction. From this viewpoint, the dome shape is sufficient as long as it is a raised shape, and therefore, the dome shape in the present invention broadly includes not only a hemispherical shape or a semi-ellipsoidal shape, which is a literal dome shape (round roof shape), but also a conical shape, a shape in which a hemisphere is superimposed on a cylinder, and the like.

The attention drawing section may be one that "at least partially contains a phosphorescent material," and includes any that uses even a small amount of phosphorescent material to emit light (hereinafter referred to as a "phosphorescent body"). A typical example is one that uses a phosphorescent silicone body. A phosphorescent silicone body is a silicone body with phosphorescent material dispersed therein, and the entire surface emits light by phosphorescence. Therefore, by making it dome-shaped, it becomes possible to see the light emitted from above or diagonally above. Details of the configuration of the attention drawing section that includes a phosphorescent silicone body will be explained in Example 3.

(Caution unit: an example of a specific configuration)
An example of the appearance of the attention drawing unit of this embodiment is shown in Fig. 2. In the example shown in Fig. 2, the attention drawing unit 0220 is formed by placing a dome-shaped phosphorescent body 0222 on a cylindrical base substrate 0221. The attention drawing unit shown in Fig. 2 also includes an insertion attachment part 0223 for fitting the attention drawing unit into the tubular part at the upper end of the pole body. A specific configuration for attaching the attention drawing unit to the pole body will be described later.

Figure 3 is a cross-sectional view showing an example of the shape of the attention drawing part of this embodiment, taken along the line X-X in Figure 2. As shown in the figure, the attention drawing part 0320 has a base substrate 0321 (shown as a grid), a phosphorescent body 0322 (shown as a line slanting upwards to the right), and an insertion mounting part 0323 (shown as a line slanting upwards to the left). Note that, although the insertion mounting part is described as a component of the attention drawing part in this specification, it is acceptable to consider the insertion mounting part to be an independent member separate from the attention drawing part, and there is no difference in technical significance between the two.

(Base substrate)
The base substrate has a tray-shaped recess on the upper surface, and the phosphorescent body is placed in the recess. For this placement, for example, as shown in the figure, a screw 0322a may be attached to the bottom of the phosphorescent body and screwed into a screw hole 0321a provided in the base substrate. In addition, it is preferable that the base substrate has a skirt portion 0321b that protrudes downward in an annular shape on the peripheral edge of the base substrate. The purpose of providing the skirt portion is to prevent rainwater, dust, etc. from entering the hollow pole of the pole body and to make it difficult for the attention calling portion to fall off the pole body by making the outer wall of the pole body tightly inscribed on the inner wall of the skirt portion when the attention calling portion is attached to the pole body. Therefore, when a skirt portion that protrudes downward in an annular shape is provided on the peripheral edge of the base substrate, it is designed so that its inner diameter is approximately the same as the outer diameter of the pole body as described above (see FIG. 7(c) below).

The preferred materials for the base substrate are metals such as stainless steel, aluminum, titanium, and brass, but they can also be ceramics (fine ceramics, pottery, glass, etc.) or hard resins (acrylic resin, polycarbonate resin, etc.).

(Internal mounting part)
The inner mounting part is for mounting the attention-calling part to the pole body. This inner mounting part may be a separate member from the base plate and attached to the base plate by means of screws or the like, or may be molded integrally with the base plate as a constituent part of the base plate.

In the above-mentioned FIG. 3, an example is shown in which the insert mounting part is a separate member from the base substrate and has a screw hole at a position corresponding to the screw hole provided in the base substrate. In this case, in order to combine the phosphorescent material, the base substrate, and the insert mounting part into an integral body to form the attention-calling part, for example, the screw holes of the base substrate and the insert mounting part are aligned and fastened with a single screw, and a phosphorescent material with adhesive applied to the dome-shaped bottom surface is attached to the top surface of the base substrate. Note that, although different from the shape shown in FIG. 3, as another configuration for combining the phosphorescent material, the base substrate, and the insert mounting part into an integral body to form the attention-calling part, a configuration in which no screw holes are provided in either the base substrate or the insert mounting part, and the phosphorescent material, the base substrate, and the insert mounting part are all attached with adhesive can also be considered.

The purpose of the insertion mounting part is to attach the warning part to the pole body. Next, we will explain the configuration for attaching the warning part to the pole body using the insertion mounting part.

Figures 4 to 7 are diagrams for explaining an example of a configuration for attaching a warning part to a pole body using an insertion attachment part. In this example, a leaf spring is attached to the bottom surface of the insertion attachment part, and the warning part is inserted into the cylindrical upper part of the pole body, so that the biasing force of the leaf spring is used to lock the insertion attachment part into the cylindrical part of the pole body.

First, as shown in FIG. 4, a leaf spring 0430 having, for example, a cross-shaped protruding portion 0431 (only one portion is labeled to avoid complication; the same applies below) is prepared. This leaf spring is attached to the bottom surface of the inner mounting portion, for example, by a screw. For this purpose, a screw hole 0432 is provided in the center of the leaf spring.

Also, FIG. 5 is a perspective view of the inner insertion mounting part as seen from diagonally below. As shown in the figure, a cross-shaped cutout portion (approximately the range indicated by the dashed ellipse 0523b; only one portion is marked to avoid complication) is formed on the bottom surface 0523a of the inner insertion mounting part 0523 to engage the protruding portion of the leaf spring. This cutout portion (approximately the range indicated by the dashed ellipse 0323b) is also shown in FIG. 3 above. The purpose of providing the cutout portion is to prevent the attached leaf spring from rotating in the horizontal direction. A screw hole 0523c is also provided in the center of the bottom surface of the inner insertion mounting part. This screw hole 0323c is also shown in FIG. 3 above. Using the above configuration, the leaf spring is screwed to the bottom surface of the inner insertion mounting part. As another configuration for preventing the attached leaf spring from rotating in the horizontal direction, a configuration in which the leaf spring is simply fixed to the bottom surface of the inner insertion mounting part by screwing it at multiple points without providing a cutout portion may be used.

Figure 6 shows the state in which the leaf spring is screwed to the bottom surface of the inner insertion mounting part, as viewed from the bottom surface of the inner insertion mounting part. As shown in the figure, the protruding part 0631 of the leaf spring protrudes outward beyond the outer periphery of the inner insertion mounting part 0623.

The protruding portion of the leaf spring (and the corresponding shape of the notch in the insert mounting portion) is not limited to a cross shape, but may be, for example, a hexagon or octagon. However, to make positioning easier, it is preferable that the vertices of the protruding portion form a regular polygon.

Next, as shown in Figure 7, the internal mounting portion in this state is inserted into the hollow pole, which is now the cylindrical portion at the top of the pole body, and the warning portion is attached to the pole body.

Of these, Figure 7(a) shows the state before insertion. As shown here, the inner diameter L1 of the hollow pole 0711 of the pole body 0710 is longer than the outer diameter L2 of the internal insertion mounting portion 0723, and shorter than the diameter L3 of the circumference inscribed by the protruding portion 0731 of the leaf spring. To avoid complication, the screw (screw head portion) for attaching the leaf spring to the bottom surface of the internal insertion mounting portion has been omitted from the illustration.

Figure 7(b) shows the state where the inner mounting portion 0723 is slightly inserted into the hollow pole 0711. At this time, due to the dimensional relationship described above, the protruding portion 0731 of the leaf spring comes into contact with the inner wall of the pole body (the wall of the hollow pole) 0710a, and is slightly bent upward. The figure shows the protruding portions protruding to the left and right and in the front direction bent upward, and although not shown in the figure, the protruding portion protruding toward the back is also bent upward (the same is true in Figure 7(c)).

Figure 7 (c) shows the state where the inner mounting part 0723 is fully inserted and mounting is complete. At this time, the protruding part 0731 of the leaf spring is bent upward significantly, and the biasing force presses against the wall 0710a of the hollow pole 0711, so that the warning part is firmly locked in place without coming off the pole body.

In the example shown in the figure, a skirt portion 0721b is provided on the peripheral edge of the base substrate of the attention drawing part, and its dimensions are designed so that when the attention drawing part is attached to the pole body, the skirt portion fits snugly against the outer wall of the pole body, as shown in Figure 7(c). This makes it possible to prevent the attention drawing part from rattling after attachment.

Furthermore, to make this installation more secure, the following configuration may be added:

Figure 8 shows an example of such a configuration, and shows an example in which a configuration for more secure attachment is applied in the range generally surrounded by the dashed circle B in Figure 7(c). Of these, Figure 8(a) shows an example in which a screw hole 0812 is provided in at least one place (preferably multiple places) on the side of the pole body 0810 and in the protruding part 0831 of the leaf spring or in addition to this at a corresponding position of the inner insertion attachment part 0823, and fastened with a screw 0850. Also, Figure 8(b) shows an example in which the tip of the protruding part 0831 of the leaf spring is abutted against a step 0813 provided on the inner wall of the hollow pole 0811. In addition, although not shown, before inserting the inner insertion attachment part into the hollow pole, adhesive may be applied to the outer surface of the lower surface (the surface that contacts the wall of the hollow pole) of the leaf spring attached to the inner insertion attachment part. Furthermore, these configurations may be appropriately combined. By attaching the attention-drawing part to the pole body more securely in this way, the attention-drawing part is less likely to fall off the pole body even during disasters, which helps to ensure proper attention. It also helps to prevent vandalism or theft, such as removing the attention-drawing part from the pole body and taking it away.

(Installation structure of warning unit: another example of specific configuration)
As another example of a suitable configuration for the structure for attaching the attention calling part to the pole body, there is a specific configuration in which the attention calling part, which is the dome part, is attached without modifying the pole body itself which is covered with a thin dome-shaped cap. With this configuration, the attention calling part can be easily attached by using the existing pole body as it is without processing it, which has the advantage that the fence structure with attention calling part according to the present invention can be provided in large quantities at low cost with simple construction.

28 is a diagram showing an example of the configuration of a fence structure with a warning part having such a configuration. Of these, (a) is a perspective view showing the upper end of the structure. In this figure, a clamping body 2860 is attached to the upper end of an existing pole body 2810. The specific configuration and attachment method of the clamping body will be described later. A fixing plate 2870 is placed on this clamping body, and a warning part 2820 is further placed on the fixing plate. The fixing plate is used to fix the clamping body and to join and place the warning part on it. Note that the clamping body may be configured as a component of the warning part, or may be a separate component from the warning part, as in the case of the internal insertion attachment part described above. In the following, the clamping body will be described as a separate component from the warning part.

Figure 28(b) is a front view of Figure 28(a). In the figure, the part indicated by the upward-left diagonal line is the clamping body 2870, and the part indicated by the upward-right diagonal line is the fixing plate 2870.

Figure 28(c) is a cross-sectional view of line A-A in Figure 28(b). As shown here, an existing pole body 2810 typically consists of a cylindrical post 2811 and a lid 2812 placed on the top end of the post, with the lid's outer diameter being slightly longer than that of the post. For example, the typical dimensions of a protective fence for a pedestrian/vehicle boundary are a post diameter of approximately 114 mm and a lid outer diameter of approximately 120 mm. The lid is typically attached to the post by welding or crimping.

As already mentioned, a clamp 2860 is placed on the top of the lid, and a fixing plate 2870 is placed on top of the clamp, and the clamp and the fixing plate are fixed by a screw 2880. Furthermore, a warning unit 2820 is placed on the top of the clamp.

Figure 29 shows an exploded perspective view of each component of such a fence structure with a warning unit. The specific configuration will be described in more detail below with reference to this figure.

(Clasping body)
As shown in Fig. 29, a clamping body 2960 is placed on the top of the lid 2912 of an existing pole body 2910, and this clamping body is composed of two divided parts 2961 and 2962, and the clamping body 2960 is attached by sandwiching and wrapping the lid with these two parts. Each part of the clamping body has a shape obtained by dividing a hollow cylinder lacking a bottom, and by connecting these parts together, a single hollow cylinder lacking a bottom is formed as a whole, which holds the lid by wrapping it. The number of divided parts of the clamping body is not limited to two, and may be three or more.

The clamp has a claw 2963 that protrudes slightly inward around the entire circumference on the bottom edge (not shown in FIG. 29, but the same is true for the divided part 2961 on the left side). The clamp is fixed to the pole body by sandwiching the lid from above and below between the claw and the top surfaces 2964 and 2965. The clamp also has screw holes (FIG. 29 shows an example in which four screw holes 2960a-d are provided, but the number of screw holes can be any number). This is for fixing the clamp itself to the fixing plate, which will be described below, by screwing. In this way, the clamp holds the lid while being fixed to the fixing plate, so there is no need to join the clamp and the lid using welding, screwing, or other joining means.

In order to properly hold the lid with the above-mentioned clamping body, it is desirable that the shape and dimensions of the clamping body are designed so that it covers the lid snugly, thereby preventing the clamping body from rattling when attached. A specific example of such dimensions will be described with reference to FIG. 35. As shown in the figure, in order for the clamping body to cover the lid snugly, the inner diameter N of the clamping body 3560 in the joined state should be approximately equal to the diameter M of the lid 3512, the dimension obtained by subtracting twice the length n of the claw portion 3563 from the inner diameter N of the clamping body should be approximately equal to the diameter m of the column portion 3511, and the height H from the lower end of the upper surface of the clamping body to the upper surface of the claw portion should be approximately equal to the height h of the lid. That is, the relationship between the inner diameter N of the clamping body when joined, the diameter M of the lid, the length n of the claw of the clamping body, the diameter m of the post, the height H from the lower end of the upper surface of the clamping body to the upper surface of the claw, and the height h of the lid should be N ≒ M, N-2n ≒ m, and H ≒ h. One example of such dimensions is when the clamping body is attached to a pole body of a pedestrian/vehicle boundary guardrail with an outer diameter N of the lid of about 120 mm, a height h of about 6 mm, and a post diameter M of about 114 mm, and the inner diameter N of the clamping body when joined is about 120 mm, the height H of about 6 mm, and the length n of the claw of about 3 mm.

The material of the clamping body is preferably hard and resistant to deformation, and suitable materials include, for example, metals (stainless steel, aluminum, titanium, brass, etc.), ceramics (fine ceramics, pottery, glass, etc.), and hard resins (acrylic resin, polycarbonate resin, etc.).

(Fixing plate, double-sided tape)
A fixing plate 2970 is fixed by screws to the upper surface of the clamping body attached in such a way that it clamps the upper end of the pole. For this reason, the fixing plate is also provided with screw holes 2970a-d at positions corresponding to the screw holes of the clamping body. As with the clamping body described above, the material of the fixing plate is preferably metal, ceramic, hard resin, or the like.

A warning section 2920 is attached to the upper surface of the fixing plate via double-sided tape 2990. The specific configuration of the warning section is the same as that already explained using FIG. 2 etc. (however, of course, the warning section in this embodiment does not have an internal mounting section).

The double-sided tape is used to tightly join the warning part on the top side to the fixed plate on the bottom side. If the base plate of the warning part and the fixed plate are both made of metal, for example, VHB (registered trademark) acrylic foam structural joining tape (product number Y-4914-015) manufactured by Sumitomo 3M Limited, which is a double-sided tape capable of joining metals, is used.

The shape of the fixing plate can be, for example, a flat plate with both flat top and bottom surfaces as shown in FIG. 29, but it may also be different and have a tray-shaped recess on the top surface of the fixing plate in which double-sided tape can be embedded and positioned.

Figure 30 shows another example of the shape of the fixing plate, in which a tray-shaped recess 3071 is provided on the upper surface of the fixing plate 3070, into which double-sided tape 3090 can be inserted and positioned.

Figure 31 shows a vertical cross-sectional view of an example of a configuration in which a warning unit is arranged on a fixed plate of such a shape. Of these, (a) shows a state in which double-sided tape 3190 is arranged in a recess 3171 of a fixed plate 3170. Next, (b) shows a state in which a base substrate 3121 of the warning unit is arranged on the upper surface of the fixed plate. With this configuration, unlike when double-sided tape and a base substrate (with a flat bottom surface) are arranged on a flat fixed plate, the sides of the fixed plate and the base substrate are adhered together without any gaps, and the sides of the double-sided tape are not exposed to the outside. This makes it possible to avoid the risk of damage, soiling, deterioration, etc. of the double-sided tape.

Although not shown in the figure, the tray-shaped recess may be provided on the underside of the base substrate of the warning unit, rather than on the top surface of the fixing plate.

Furthermore, in the configuration in which the fixing plate has a tray-shaped recess as described above, the central portion 3222 of the lower surface of the base substrate 3221 may be slightly recessed as shown in FIG. 32. This allows the double-sided tape 3290 placed in the tray-shaped recess on the upper surface of the fixing plate 3270 to be placed in a state where it protrudes above the upper surface of the fixing plate, and the double-sided tape can be attached over a wider area. Furthermore, if the material of the double-sided tape is highly flexible like the acrylic foam described above, the double-sided tape can be deformed to match the shape of the recess on the lower surface of the base substrate, so that the double-sided tape and the base substrate can be more appropriately attached to each other. In addition, the relationship between the depth of the recess in the fixing plate and the thickness of the double-sided tape can be designed with more freedom, which can contribute to making the design and manufacturing of the attention-attracting portion including the fixing plate easier. The above also applies to the case in which the tray-shaped recess is provided on the lower surface of the base substrate of the attention-attracting portion.

(Screw hole)
Furthermore, in order to prevent rattling caused by the screws, it is desirable that the dimensions of the screw holes of the clamping body and the fixed plate combined are long enough to securely fasten the screws. Figure 34 is a conceptual diagram showing an example of such a configuration, and as shown in (a), in this example, the part of the clamping body that forms the screw hole is shaped to protrude toward the underside. (b) is a comparative example for reference, in which the dimensions of the screw holes are not long enough to securely fasten the screws.

Figure 33 is a diagram for further explaining a preferred example of the shape of the screw hole, and is an enlarged view of the portion roughly surrounded by circle B in Figure 28(c). As shown in the figure, in this example, the portion 3370a of the screw hole that receives the head is formed deep, and is formed so that the head of the screw does not protrude above the fixing plate. This makes it possible to fix the base substrate perfectly horizontally without any rattling, even if the bottom surface of the base substrate is flat.

You can also fill the space in the screw hole of the fixing plate that appears above the head of the screw with gel. This will prevent rainwater, dust, etc. from entering the inside of the clamp through the screw hole and deteriorating the fence structure with warning parts.

＜Effects＞
According to the invention of this embodiment, by using a phosphorescent material in the attention-attracting section, even pedestrians who do not carry a light source at night can recognize the position of the fence, making it possible to appropriately alert them to prevent falls, etc. In addition, by making the phosphorescent material dome-shaped, it is possible to effectively alert pedestrians who are in a position to see the cap from above or diagonally above.

＜Overview＞
The invention of this embodiment is a road, square, river or port facility equipped with the fence structure with an attention-attracting part described in the first embodiment.

<Configuration>
(Road equipped with a fence structure with warning devices)

As seen in Example 1, the fence structure with warning parts according to the present invention allows passersby who do not carry a light source at night to recognize the position of the fence, making it possible to properly warn people to prevent falls, etc. Therefore, by providing a fence structure with warning parts in facilities where there is a need for such warnings, it is possible to provide safe facilities that can prevent dangers such as falls.

For example, when the road edge borders a gutter, cliff, rice field, river, etc., a fence structure with a warning unit can be installed on the boundary to provide a road that can prevent falls even at night. In particular, during large-scale disasters such as heavy snowfall or flooding, most of the fence structure with a warning unit may be buried in snow or water, leaving the warning unit exposed at a height of several centimeters to several tens of centimeters above the snow or water. In such cases, the line of sight of pedestrians walking or boating on the snow or water will be in a position to look down on the warning unit from above or diagonally above. However, unlike conventional fence structures that only have a horizontal reflection function, the fence structure with a warning unit according to the present invention is equipped with a dome-shaped phosphorescent body, making it possible to effectively warn people in such cases.

In addition, for example, by making a fence installed at the boundary between a roadway and a sidewalk into a fence structure with such a warning part, it is possible to provide a road equipped with a fence structure that can achieve a similar effect.

(Open space equipped with a fence structure with warning devices)
With regard to plazas as well, for example, by installing a fence structure with a warning section at the boundary between the plaza and the surrounding road, it is possible to provide a plaza equipped with a fence structure that can achieve the same effect as described above.

(Rivers equipped with fence structures with warning devices)
With regard to rivers as well, for example, by installing a fence structure with a warning section at the boundary between the river and the riverbed, it is possible to provide a river equipped with a fence structure that can achieve the same effect as described above.

(Port facility equipped with fence structure with warning devices)
With regard to port facilities as well, for example, by installing a fence structure with a warning part at the boundary between a quay or pier and the port, it is possible to provide port facilities equipped with a fence structure that can achieve the same effect as described above.

(others)
The above are examples of main facilities, and in addition, by installing fence structures with warning parts around lakes and ponds, on the rooftops of buildings, etc., it is possible to provide facilities equipped with fence structures that can achieve the same effects as those described above. In short, if there is a facility that needs to prevent dangers such as falls at night, the effect of providing a safe facility can be achieved by installing a fence structure with warning parts according to the present invention, and all of these facilities equipped with such fence structures with warning parts fall within the technical scope of the present invention.

＜Effects＞
According to the invention of this embodiment, by providing a fence structure with a warning part having the configuration and effect described in embodiment 1, it is possible to provide a safe facility that can prevent risks such as falls.

＜Overview＞
In this embodiment, the warning portion of the fence structure with a warning portion described in Example 1 is made up of a base substrate, a reflective layer arranged on the base substrate, a gel adhesive layer arranged on the reflective layer, a phosphorescent silicone body which is a silicone body with dispersed phosphorescent material arranged on the gel adhesive layer, and a glass coating layer covering at least the phosphorescent silicone body.

<Configuration>
The configuration of the fence structure with an attention drawing part of this embodiment is basically the same as the configuration of the fence structure with an attention drawing part described in Example 1. However, the fence structure with an attention drawing part of this embodiment is characterized in that the attention drawing part comprises a base substrate, a reflective layer disposed on the base substrate, a gel adhesive layer disposed on the reflective layer, a phosphorescent silicone body which is a silicone body in which a phosphorescent material is dispersed and disposed on the gel adhesive layer, and a glass coating layer covering at least the phosphorescent silicone body.

Figure 9 is a cross-sectional view showing an example of the shape of the attention part of the fence structure with attention part of this embodiment. The attention part 0920 shown in the figure consists of a base substrate 0921, a phosphorescent silicone body 0922, a reflective layer 0926 arranged on the base substrate, a gel adhesive layer 0927 arranged on the reflective layer, and a glass coating layer 0928 coated on the phosphorescent silicone body. As an attention part having such a configuration, the configuration described in the specification of a patent application (Patent Application No. 2019-073816) relating to a phosphorescent silicone marker by the same applicant as the applicant of the present invention can be used. Below, an overview of the configuration will be described for each component. Note that the configuration of the base substrate is the same as that described above, so the description will be omitted. In addition, an internal insertion attachment part may be provided as a component of the attention part, but the configuration of the internal insertion attachment part in that case is the same as that described in Example 1, so the description will be omitted. Furthermore, the configuration for attaching the phosphorescent silicone body to the base substrate and the inner mounting portion, and the configuration for attaching the inner mounting portion to the pole body are similar to those described in Example 1, so their explanations are omitted and they are not shown in the figure.

(Luminous silicone body)
The light-storing silicone body is a silicone body in which a light-storing material is dispersed. For example, a strontium aluminate-based light-storing powder is used as the light-storing material. The strontium aluminate-based light-storing powder refers to a powder in which a small amount of europium (Eu), dysprosium (Dy), boron (B), etc. is added to a strontium aluminate salt as a mother crystal. It is desirable to use a liquid silicone to which the light-storing powder is mixed that is as transparent as possible. For example, a method of forming the light-storing silicone body is used in which a powdered light-storing material is mixed into a silicone liquid poured into a mold such as a bowl-shaped, fish cake-shaped, frying pan-shaped, or pot-shaped mold, and the powder is allowed to settle by leaving it still for a certain period of time, and then the silicone liquid is placed on a hot plate and heated at 120 degrees Celsius for about 10 minutes, and then the silicone liquid is hardened by heating it at 120 degrees Celsius for about 2 hours using a hot oven (with drying function), and the hardened light-storing silicone body is removed from the mold. It is also possible to process the mixture so that a pigment is mixed at the same time in addition to the phosphorescent material. The color of the pigment (multiple pigments may be mixed) determines the color during the daytime. The distribution state of the phosphorescent material in the silicone body can be adjusted in various ways by changing the standing time. For example, by curing before the phosphorescent powder has completely settled, it is possible to obtain a silicone body in which the phosphorescent powder and the pigments mixed at the same time (multiple pigments may be made to draw patterns independently in some cases) are distributed in a gradational manner. The mold may also be rotated or swung before curing. Such a specific example will be described later in another embodiment.

Alternatively, the light-storing silicone body may have a structure in which a plurality of light-storing materials made of materials with different luminous colors are layered. Various luminous colors are known for light-storing materials, such as red, yellow, green, blue-green, and blue. For example, JP 2011-189558 A discloses a light-storing material in which a small amount of copper is added as an activator to zinc sulfide crystals (the luminous color is yellow to red depending on the composition), a light-storing material in which a small amount of copper is added as an activator to zinc sulfide (the luminous color is green), and a light-storing material in which europium is added as an activator to aluminate or a rare earth element or transition metal is added as a co-activator (the luminous color is green or blue). Therefore, for example, it is conceivable to form a light-storing silicone body by repeatedly pouring and curing liquid light-storing materials of each color so that the luminous colors are red, yellow, and blue from the bottom up. In this case, by adding rocking or rotation during the curing process, a gradation may be applied within each layer or over the entire body. This configuration allows each color and its combination to have its own unique meaning, providing a fence structure with warning parts that displays a variety of content.

(Reflective Layer)
The reflective layer is a layered member including a reflective material arranged on a base substrate, and is intended to reflect light from the phosphorescent silicone body toward the phosphorescent silicone body to improve the luminance of the phosphorescent silicone body. White pigments such as titanium oxide and silica are suitable as the reflective material, and the reflective layer can be formed by applying these to the base substrate. Alternatively, a reflective film or reflective sheet containing a white pigment as in the above example can be used using polyvinyl chloride (PVC), acrylic resin (PMMA), PET, or the like as a base material, and for example, a reflective film manufactured by 3M (product name: Light Enhancement Film 3635-100 White) is used.

In addition, the reflective layer may not be provided near the center of the base substrate. For example, in a configuration in which the phosphorescent silicone body is placed on a base substrate screwed to the insert mounting portion at the center as shown in FIG. 3, the screw hole penetrates to the upper surface side of the base substrate. In this case, if the screw head is shaped to protrude above the base substrate, the reflective layer will not be formed in the screw hole portion. In this case, a recess is provided on the bottom surface of the phosphorescent silicone body, and if the thickness of the phosphorescent silicone body is thick, it is possible to provide an area where the gel adhesive layer and the reflective layer are not provided in the part that corresponds to the bottom surface of the part near the center of the phosphorescent body where the thickness is 1 centimeter or more. This configuration is based on the fact that if the thickness of the phosphorescent silicone body near the center is large (about 1 centimeter or more), the phosphorescent material near the part that contacts the center of the base substrate hardly emits light, so there is little point in providing a reflective material. On the other hand, even if the screw holes penetrate all the way to the top surface of the base substrate, it is possible that the screw heads do not protrude above the base substrate and are flush with it. In this case, a reflective layer can be provided on the entire surface of the base substrate and the screw heads. In this case, a reflective layer will also be provided near the center of the base substrate.

(Gel Adhesive Layer)
The gel adhesive layer is a member made of a transparent gel material arranged on the reflective layer. The purpose is to use the adhesiveness and flexibility of the gel to press the reflective layer and the phosphorescent silicone body without using adhesive. In addition, by pressing the reflective material and the phosphorescent silicone body without any gaps, air can be prevented from entering between the reflective layer and the phosphorescent silicone body, and the attenuation of light between them can be prevented. In addition, since there is no need to interpose a member made of a different material, namely an adhesive, the attenuation of light between the reflective layer and the phosphorescent silicone body can also be prevented from this point of view. In this specification, "transparent" includes both colorless transparent and colored transparent (the same applies to other components).

Transparent silicone gel and transparent acrylic gel are suitable as the transparent gel material. In view of the purpose of adhering the reflective layer and the phosphorescent silicone body without air getting in between, the shape of the gel adhesive layer should be approximately the same as the planar shape of the reflective layer and the bottom shape of the phosphorescent silicone body, and in view of its flexible characteristics, it is desirable that the thickness is not too thick. An example of the thickness before use is about 0.1 to 0.3 millimeters. The gel adhesive layer may be a double-sided tape. A specific example will be described later in another embodiment. When placing the gel adhesive layer on the reflective layer and then placing the phosphorescent silicone body, the gel adhesive layer is pressed by the phosphorescent silicone body, and work is performed so that no air bubbles remain between the two. The pressing force is about 400 grams/square centimeter to 1 kilogram/square centimeter on average per unit area of the gel adhesive layer. If too much force is applied to the phosphorescent silicone body, it may be damaged, so the risk of damage can be reduced by wrapping the upper part of the phosphorescent silicone body with a relatively soft member such as cloth and pressing it.

It is preferable that the material of the gel adhesive layer is one that is unlikely to undergo a chemical reaction with the phosphorescent silicone body. This is to prevent the composition of the adhesive portion of the phosphorescent silicone body with the gel adhesive layer from becoming the same as the composition of the other portions of the phosphorescent silicone body, which could result in a deterioration of the luminous performance.

In relation to the configuration of providing a protrusion with a screw head exposed on the upper side of the base substrate described in the description of the base substrate and the reflective layer, depending on the dimensions and shape of the screw head, a recess may also be provided near the center of the bottom surface of the phosphorescent silicone body. This configuration has the advantage of being able to save material near the bottom of the thicker part of the phosphorescent silicone body that does not contribute to light emission.

(Glass coating layer)
The glass coating layer is a layer-like member made of glass that covers all or part of the surface of the phosphorescent silicone structure to protect it from scratches, water damage, dust, etc. Since the phosphorescent silicone body is particularly vulnerable to such damage, and damage directly leads to the inhibition of light emission at high luminance, it is essential that the glass coating layer covers at least the phosphorescent silicone body.

The warning portion shown in FIG. 9 is formed so that the inner wall 0921a of the tray-shaped recess in the base substrate is angled outward, and the peripheral shape 0922a of the phosphorescent silicone body is angled inward. In the case of such a shape, even when only the phosphorescent silicone body is covered, it is desirable to prevent the end faces of the gel adhesive layer and the reflective layer from being directly exposed to the outside air. Therefore, an example of the configuration in such a case will be explained using the figures.

Figure 10 is a diagram for explaining an example of how to form a glass coating layer. The area shown in this figure corresponds to the area indicated by the dashed circle 0902 in Figure 9. As shown in this figure, the glass coating layer is provided so as to form a liquid pool in the valley formed by the inner wall of the tray-shaped depression and the inwardly sloping surface of the phosphorescent silicone layer. As a premise, in the example of this figure, a method of applying liquid glass with a certain degree of viscosity is used as the glass coating method (details of the glass coating method will be described later).

In the example of FIG. 10(a), the glass coating layer 1028 (shown in light ink) is arranged so as to completely fill the valleys all the way to the bottom. As a result, the glass coating layer not only completely covers the phosphorescent silicone body 1022, but also completely covers the end surface 1027a of the gel adhesive layer 1027 and the end surface 1026a of the reflective layer 1026. This protects the end surfaces of the gel adhesive layer and the reflective layer from scratches, water, and dust.

On the other hand, in the example of FIG. 10(b), the glass coating layer 1028 (shown in light ink) does not completely fill the valleys all the way to the bottom, and there is a space at the bottom of the valley where the glass coating layer is not placed. This is thought to occur when the viscosity of the liquid glass is high. In this case, the glass coating layer 1028 completely covers the phosphorescent silicone body 1022, but the end surface 1027a of the gel adhesive layer 1027 and the end surface 1026a of the reflective layer 1026 may not be covered (the example in the figure is such an example). However, even in this case, the end surfaces of the gel adhesive layer and the reflective layer are sealed under the glass coating layer, so to speak, and are not exposed to the outside air. Therefore, the end surfaces of the gel adhesive layer and the reflective layer are still protected from scratches, water, and dust.

In this way, in both cases of Figure 10 (a) and (b), the glass coating layer protects the end faces of the gel adhesive layer and the reflective layer from scratches, water damage, and dust. This is because the shape of the valley and the positional relationship between the end faces of the glass coating layer, the gel adhesive layer, and the reflective layer are configured as shown below.

That is, as shown in FIG. 10(a), if the top of the side wall of the base substrate is A, the top of the end face of the gel adhesive layer is B, the bottom of the end face of the gel adhesive layer (top of the end face of the reflective layer) is C, and the bottom of the end face of the reflective layer is D, the lowest position H of the valley of the glass coating layer is configured to be lower than A and higher than B, C, and D. In this manner, the liquid glass can fill the valley without flowing out of the side wall of the base substrate during the glass coating layer formation process, and if this filling is continued, a liquid pool can be formed that completely fills the valley from the bottom of the valley to position H higher than B with the glass coating layer. In the case of FIG. 10(b), a liquid pool that seals the valley at a position higher than B can be formed in the same manner.

On the other hand, if the gel adhesive layer or, in addition, the reflective layer is exposed on the base substrate, it is desirable that the glass coating layer be configured to cover the exposed gel adhesive layer and reflective layer. Specific examples of this will be described later in another embodiment.

For example, room temperature glass coating is used as a method of glass coating. Room temperature glass coating is a coating method that forms a glass film at room temperature (generally room temperature to 200°C) and does not require a high-temperature heat treatment step in the conventional glass manufacturing process. Specifically, for example, Cosmo Technology's room temperature glass coating system (product name: SL-600 series) can be used. Room temperature glass coating is excellent in weather resistance and stain resistance, as well as water resistance and abrasion resistance. Considering that phosphorescent materials are generally vulnerable to water and that fence structures with warning parts are installed on road surfaces and are easily stepped on by pedestrians, it is an extremely suitable method as a glass coating method according to the present invention.

Examples of materials for room temperature glass coating include alcohol-soluble organic silicon compounds and other metal compounds (organic and inorganic). More specifically, the silicon content (SiO ₂ ) in the components is 60% or more by weight, and pigments and aggregates are added as necessary. The components are liquid and solvent-free organopolysiloxane, functional side chain alkoxysilane, ionized metal compounds (organic and inorganic), and catalysts. The glass coating layer may be formed in multiple steps using a spray, or the viscosity of the liquid glass may be adjusted to increase the thickness that can be applied in one step, thereby reducing the number of applications. In order to increase the viscosity, it is possible to increase the silicon content. For example, if the weight percent is about 70% to 80%, a sufficiently thick glass layer can be formed even for a dome-shaped phosphorescent silicone body. If the weight percent is about 70%, the thickness can be about 0.3 to 0.7 millimeters. With this thickness, weather resistance can be sufficiently ensured, except when a large force is applied from above. In addition, since it is not too thick, it transmits ultraviolet light to a certain extent and does not interfere with the supply of energy to the phosphorescent material.

＜Overview＞
The fence structure with warning parts of this embodiment is basically the same as that of embodiment 3. However, this embodiment is characterized in that the phosphorescent silicone body is configured so that the density of the phosphorescent material on the outer surface side is greater than the density of the phosphorescent material on the central side.

<Configuration>
FIG. 11 is a diagram showing an example of the configuration of the phosphorescent silicone body in the fence structure with the attention-calling part of this embodiment, and is shown in a vertical cross-sectional view near the center. As shown in the figure, in this embodiment, the distribution density of the phosphorescent material (shown by dots) on the outer surface side of the phosphorescent silicone body 1122 is relatively dense, and the distribution density of the phosphorescent material on the center side is relatively sparse. That is, the density of the phosphorescent material on the outer surface side is greater than the density of the phosphorescent material on the center side. Note that the center of the phosphorescent silicone body refers to the part farthest from the surface of the phosphorescent silicone body, and in accordance with the example of FIG. 11, the central part of the lower surface of the phosphorescent silicone body (the part located directly below the top of the phosphorescent silicone body). The outer surface side refers to the part of the phosphorescent silicone body that is relatively closer to the outer surface than the center, and the center side refers to the part that is relatively closer to the center than the outer surface.

The configuration of this embodiment is based on the idea that, for the same amount of phosphorescent material, distributing more of the phosphorescent material closer to the outer surface can increase the luminance of the phosphorescent silicone body. The procedure for forming a phosphorescent silicone body with this configuration will be described later.

＜Effects＞
According to this embodiment, since the phosphorescent material can be distributed more toward the surface side of the phosphorescent silicone body, the luminescence brightness of the phosphorescent silicone body can be relatively increased.

＜Overview＞
The fence structure with warning parts of this embodiment is basically the same as that of embodiment 3 or 4. However, this embodiment is characterized in that the glass coating layer is configured to cover the boundary part exposed on the outer surface between the phosphorescent silicone body and the gel adhesive layer. This configuration is particularly significant when the upper surface of the base substrate is a flat surface without side walls.

<Configuration>
FIG. 12 is a cross-sectional view showing an example of the shape of the attention drawing part of the fence structure with the attention drawing part of this embodiment. The upper surface of the base substrate 1221 shown in the figure has a planar shape without side walls, unlike the example shown in FIG. 9 and the like. And, as shown in the figure, in this embodiment, unlike the one shown in FIG. 9 for Example 3, the glass coating layer 1228 covers not only the light-storing silicone body 1222 but also the gel adhesive layer 1227 and the reflective layer 1226, which are other components of the light-storing silicone structure. If the base substrate as shown in FIG. 9 has a shape with a side wall on the upper surface, the gel adhesive layer and the reflective layer can be covered by the method of forming a liquid pool in the glass coating layer described using FIG. 10. However, if the upper surface of the base substrate has a planar shape without a side wall as in the example of the figure, the method of forming a liquid pool cannot be used. Therefore, this embodiment provides a configuration that enables the glass coating layer to cover the boundary part exposed on the outer surface between the light-storing silicone body and the gel adhesive layer even if the base substrate is flat.

A specific configuration for realizing such a configuration, that is, a configuration for forming a glass coating layer at the interface of the gel adhesive layer and the reflective layer without liquid pooling, is to allow liquid glass to remain in the minute step (annular depression) that occurs at the interface between the gel adhesive layer and the reflective layer by capillary action and then dry. In addition, instead of simply leaving the dome with its top facing up and drying it, it is also possible to rotate the dome around its axis with the axis parallel to the ground and dry it. This is because the liquid glass is less likely to flow out from the annular depression. By configuring it in this way, the end faces of the gel adhesive layer and the reflective layer that appear on the surface of the phosphorescent silicone structure can also be covered, and the weather resistance and dirt resistance of the phosphorescent silicone structure can be increased. In particular, such a covering is extremely effective because dust is easily attached to the end face of the gel adhesive layer due to the adhesive force of the gel.

＜Effects＞
According to the invention of this embodiment, weather resistance and stain resistance can be further improved.

＜Overview＞
The fence structure with a warning part of this embodiment is basically the same as any one of the embodiments 3 to 5. However, this embodiment is characterized in that a gel covering part is further provided under the glass covering layer at the boundary part exposed on the outer surface between the phosphorescent silicone body and the gel adhesive layer.

<Configuration>
Fig. 13 is a diagram showing an example of the configuration of the attention drawing part in the fence structure with an attention drawing part of this embodiment, and shows an enlarged view of a part roughly corresponding to the part indicated by the dashed circle 0902 in Fig. 9. However, unlike the part shown in Fig. 9, in this figure, a gel covering part 1329 is further provided under the glass covering layer 1328 at the boundary part exposed on the outer surface between the light-storing silicone body 1322 and the gel adhesive layer 1327.

The purpose of this configuration is to prevent dust from accumulating in the corners and gaps of the joint between the phosphorescent silicone structure and the base substrate, and to prevent water from seeping in through these. It is placed under the glass coating layer to prevent dust from adhering to the adhesive gel coating. However, if there is too much moisture on the gel surface at the contact interface between the gel coating and the glass, the hardening of the liquid glass at that area may be delayed, so it is possible to dry the surface of that interface before applying or spraying the liquid glass. Drying is done by blowing dry air at about 70 to 120 degrees Celsius using a dryer or similar device. If the dome radius is a few centimeters, drying can be done in an instant, so the time is about 1 to 2 seconds, and even if the gel layer is thick, about 3 seconds is sufficient.

＜Effects＞
The invention of this embodiment makes it possible to prevent dust from accumulating in the corners and gaps of the joint between the phosphorescent silicone body and the base substrate, and to prevent water from entering through these corners and gaps.

＜Overview＞
The fence structure with a warning portion of this embodiment is basically the same as any one of the embodiments 3 to 6. However, this embodiment is characterized in that the gel adhesive layer is made of double-sided tape.

<Configuration>
FIG. 14 is a cross-sectional view showing an example of the configuration of the gel adhesive layer in the attention-attracting portion of the fence structure with an attention-attracting portion of this embodiment. As shown in the figure, the gel adhesive layer 1427 of this embodiment is a double-sided tape and has a double structure. More specifically, a transparent silicone rubber 1401 is arranged in the center, and a transparent silicone adhesive 1402 is arranged in the upper and lower layers that directly contact it. The upper and lower layers are peelable films 1403. Since the transparent silicone adhesive and the transparent silicone rubber have a high affinity, by using such a double-sided tape, the reflective material and the phosphorescent silicone body can be more reliably pressed together, and the pressing can be performed with a simple operation.

The transparent silicone adhesive material of the double-sided tape is preferably a silicone gel material with excellent heat resistance, durability and cushioning properties, and the transparent silicone rubber material placed in the center is also preferably one with similarly excellent cushioning properties. As a double-sided tape using such a material, for example, double-sided tape manufactured by Sliontec Co., Ltd. (product name: No. 5710) can be used. The configuration shown in Figure 14 is also an example of such a product.

＜Effects＞
According to the invention of this embodiment, the reflective material and the phosphorescent silicone body can be more reliably bonded together by pressure, and the bonding can be performed by a simple operation.

＜Overview＞
The fence structure with a warning part of this embodiment is basically the same as any one of the embodiments 3 to 7. However, this embodiment is characterized in that the surface of the phosphorescent silicone body is painted with characters, figures, symbols, colors, or combinations thereof that can be recognized by human vision (hereinafter referred to as "characters, etc."). The first purpose is to display the contents of the warning more clearly and specifically by painting characters, etc. on the surface of the phosphorescent silicone body of the warning part. For example, characters such as "Watch out for falls" can be displayed on the warning part of a fence structure installed on the roadside along a cliff.

A second object of this embodiment is to enable the fence structure with warning parts to be used as a guide sign in the event of a disaster. In other words, it is desirable for the guide sign to be able to reliably guide disaster victims to evacuation shelters etc. in the event of a disaster, and since the multiple pole bodies that make up the fence structure are often installed at relatively short intervals, for example every two meters, by making the warning part provided at the top of the pole body a guide sign using letters etc., it is possible to provide a fence structure equipped with a guide sign that is easy to see in the event of a disaster and can reliably guide disaster victims to evacuation shelters etc.

<Configuration>
FIG. 15 is a diagram showing an example of the configuration of the attention calling part in the fence structure with the attention calling part of this embodiment, and shows a state in which characters 0941 are drawn on the surface of the phosphorescent silicone body 0940. Among these, the one shown in FIG. 15(a) is assumed to be a warning part for preventing falls, and the one shown in FIG. 15(b) is assumed to be a guidance part for indicating an evacuation site in the event of a disaster. As shown in these examples, it may be drawn using only one type of character, figure, symbol, color, etc. (example (a)), or it may be drawn using a combination of characters, figures, symbols, colors, etc. (example (b)). In short, it is sufficient that something that can be recognized by human vision is drawn. To draw these characters, etc., a method of applying an opaque paint to the surface of the phosphorescent silicone body or attaching an opaque sheet may be used. In this case, the glass coating layer is formed so as to coat these paints, sheets, etc. (the parts where these are not placed are directly coated with the phosphorescent silicone body).

The first objective of this embodiment is to make it possible to specifically convey the contents of a warning, etc., not only through the presence of the attention-calling unit with a phosphorescent display function, but also through the meaning of the characters drawn thereon, as described above. For example, when a fence structure with an attention-calling unit is installed at the edge of a cliff or river, or at the boundary between a gutter and a road shoulder to warn of the risk of falling, the presence of the attention-calling unit with a phosphorescent display function alone can notify the location of the edge of the road, etc., and thus serves as a sufficient warning display, but in order to more specifically detect the danger, it is conceivable to add characters such as "Stop" or "Watch out for falling". For this reason, when drawing figures, symbols, or colors, it is desirable to draw those that have a meaning assigned to them in advance. For example, it is conceivable to draw a square, an "!" symbol, or red color with the meaning of "Stop" assigned to them in advance.

The second purpose of using them as signs for evacuation guidance is to make it possible to specifically convey the content of the guidance through the meaning of the letters etc. drawn on them. For example, by displaying the letters "Large-area Evacuation Site Ko Park" on the attention-calling section of a fence structure installed along the road leading to a large-area evacuation site, together with an arrow showing the direction to the site and the distance to the site, disaster victims can be reliably guided to the large-area evacuation site. In this case too, when drawing shapes, symbols or colors, it is desirable to draw ones that have a meaning attached to them in advance, just as in the case of using them for the first purpose of calling attention.

As a configuration for drawing letters, etc., it is possible to, for example, place reflective material such as reflective tape or reflective sheeting on the surface of the phosphorescent silicone body to draw the shape of letters, etc., or to place non-transparent tape, sheeting, etc.

＜Effects＞
According to the invention of this embodiment, in addition to the presence of the attention-calling unit with a phosphorescent display function, it is possible to specifically convey the contents of the warning, etc., by the meaning of the characters, etc., drawn thereon. It can also be used for evacuation guidance in the event of a disaster, and the contents of the guidance can be specifically conveyed by the meaning of the characters, etc., drawn thereon.

＜Overview＞
In the above, an example of a configuration in which the attention drawing portion constituting the fence structure has a base substrate, a reflective layer, a gel adhesive layer, a dome-shaped phosphorescent silicone body, and a glass coating layer has been described. As mentioned at the beginning, the attention drawing portion broadly includes those containing phosphorescent material in at least a part of the dome portion, so other configurations are also possible. This embodiment is one such example, in which the attention drawing portion is a transparent dome-shaped plano-convex lens arranged on the upper surface of a flat plate-shaped phosphorescent sheet.

<Configuration>
(General)
FIG. 16A is a diagram showing an example of the configuration of the attention calling part of the fence structure with attention calling part of this embodiment, and is shown in a perspective view with the components separated. As shown in the figure, the attention calling part 1600 in this example has a base 1601, a reflector 1602, a silicone gel film 1603, and a plano-convex lens 1604. As an attention calling part having such a configuration, the configuration described in the specification of a patent application (Patent Application No. 2019-177092) related to a sign by the same applicant as the applicant of the present invention can be used. Below, an overview of the configuration will be described for each component. Although not shown in the figure, an insert attachment part having a configuration similar to that described in Example 1 is attached to the underside of the base. The fact that this insert attachment part may be a component of the attention calling part or a component separate from the attention calling part is the same as that described in Example 1. The specific configuration of the insertion mounting part is the same as that described in Example 1, and the configuration relating to the mounting between the base and the hollow pole is also the same as that described in Example 1 for the configuration relating to the mounting between the base board and the hollow pole. Therefore, the description of these will be omitted.

(base)
The base is made of a truncated cone-shaped metal material. Since it is installed on roads, etc., it must be a strong material that is not easily deformed by pedestrians' footsteps, and must also be resistant to seasonal and daytime temperature differences and corrosion caused by acidic substances contained in rainwater and exhaust gas. In addition, since it is familiar to people (children) and pets such as dogs and cats, it is required to be non-toxic. In addition, taking into consideration characteristics such as cost, ease of maintenance, workability, decorativeness, specific strength, and electromagnetic wave and heat reflection, for example, stainless steel, aluminum, aluminum alloy, copper, copper alloy, etc. are suitable.

The top surface of the base (indicated by reference numeral 1605 in FIG. 16A) is a horizontal, flat surface, since it is the surface that serves as the base for the plano-convex lens. In addition, since the plano-convex lens is adhered to it using a silicone gel film, the surface must be smooth and free of roughness.

In addition, because the frustum shape is wider as it approaches the bottom, stable installation can be expected, and for example, it is expected that the incident light from the headlights of a car will be incident from a slightly diagonal upward direction of the sign, and the incident angle of the incident light will be close to a right angle to the side of the base, which has the effect of increasing the brightness of the reflected light due to retroreflection by the reflective material described below that enters the driver's field of vision. In addition, since there is no bias in a specific direction on the side, there are no restrictions on the direction of installation of the base. In addition, as described below, a reflective material is provided on the side of the base, and since the side of this base is in a truncated cone shape, light incident from a diagonal upward direction is easily reflected in that direction, which is suitable for the purpose of the present invention, which is to easily alert those who view the attention-attracting portion from above or diagonally upward.
In addition, although different from this embodiment, the shape of the base may be cylindrical instead of a truncated cone. In this case, the reflecting material described below is arranged on the vertical side of the cylinder, so the effect of the reflection itself is the same as that of the reflecting material provided on the conventional cap. However, the feature of the attention-attracting part in the fence structure with the attention-attracting part of this embodiment is that it is possible to effectively attract the attention of passersby who do not have a nighttime light source and are looking down on the attention-attracting part from above or diagonally above, due to the effect of the planar phosphorescent member described below and the plano-convex lens arranged on it. The attention-attracting effect of the reflected light from the reflecting material, combined with the effect of the phosphorescent attention-attracting effect, makes it possible to attract attention over a wide range regardless of the presence or absence of a light source as a whole, so the configuration in which the reflecting material is arranged on the side of the cylindrical base is also sufficiently significant.
Figure 16B is a diagram showing an example of the configuration of the warning portion of a fence structure with a warning portion of this embodiment, and is an example in which the base shape is cylindrical (the rest of the configuration is the same as that shown in Figure 16A).

(Reflective material)
The reflection by the reflective material arranged on the side of the truncated cone of the base must be a retroreflection that reflects light emitted from the headlights of a car or bicycle, which is a light source at night, in a direction parallel to and opposite to the light source. In other words, even from an obliquely upward direction, a car or bicycle driver or a pedestrian carrying a flashlight can capture the reflected light of the light they emitted by returning it to themselves without waste. Retroreflection can be achieved by uniformly mixing and arranging a large number of very small (e.g., several tens to 100 μm in diameter) high-refractive index glass beads in a resin or paint, and surrounding the vicinity of the lower side with a reflective layer (e.g., an aluminum vapor deposition layer, etc.). In other words, a focal layer is formed in which the incident light is focused near the lower half of the transparent glass beads by the lens effect of the high-refractive index glass beads. Here, the incident light is reflected by the reflective layer surrounding the focal layer, and the reflected light passes through the focal layer again, re-enters the glass beads and refracts, and finally travels toward the light source in a direction almost parallel to and opposite to the incident light from the light source. Such glass bead type reflectors include exposed lens types in which the spherical lens is exposed, encapsulated lens types in which the upper part of the spherical lens is covered with resin, and capsule lens types in which an air layer is provided between the spherical lens and the resin film. Normally, the incident light is white light such as that from a car headlight, but by disposing a coloring agent in the film that covers the surface of the glass bead ball or in the focal layer, the reflected light becomes colored light according to the spectral transmittance characteristics of that coloring agent.

There are also prism lens type retroreflective materials (soft or hard) that use prisms in the shape of right-angled triangular pyramids and have high reflective performance even when light is incident from various angles. The currently mainstream is the capsule prism type reflective material, which has excellent properties of high brightness and high durability. This is a reflective material that uses full cube corner reflective elements and arranges only the parts that contribute to reflection, and is preferably used as a reflective material for signs. For example, the glass bead type high brightness reflective sheet manufactured by 3M has about twice the reflective brightness of the conventional capsule lens type reflective sheet, has significantly increased surface strength and is scratch resistant, and has excellent wide-angle characteristics, so it can be clearly seen even from an oblique direction, and is said to have durability that maintains the initial reflective performance for a long period of time. In addition, glass does not deteriorate due to ultraviolet rays, so it is suitable as a material for the retroreflective sheet adopted in the present invention. Alternatively, a retroreflective sheet using a transparent epoxy material with good weather resistance may be used.

The JIS standard (JIS Z9117:2011) for the durability of such retroreflective materials requires that they maintain 80% of their initial brightness and that their hue falls within a specified chromaticity coordinate frame even after 10 years of exposure outdoors facing south.

(Silicone gel film)
Silicone gel film has the weather resistance, heat resistance, cold resistance, corrosion resistance, electrical insulation, transparency, and other properties unique to silicone, and as it becomes a gel after curing, it has excellent adhesion and adhesion. The silicone gel film is placed and attached between the bottom of a plano-convex lens made of silicone material and the top surface of the truncated cone of the base. Since the plano-convex lens and the silicone gel film are made of the same material, they have a high affinity, and the silicone gel film flexibly follows the thermal expansion and contraction of the plano-convex lens, preventing the attached part from peeling off.

(Plano-convex lens)
A "plano-convex lens" is a convex lens with a flat bottom surface. If the bottom surface is flat, it becomes easier to stably hold the plano-convex lens by making the top surface of the truncated cone-shaped base flat. It is possible to hold a convex lens with a shape other than flat, but this is difficult to design and manufacture, so it is most efficient to use a flat surface to hold the plano-convex lens.

FIG. 17A is a conceptual diagram for explaining an example of a specific configuration of a plano-convex lens. As shown in the figure, a plano-convex lens 1702 may be configured so that the bottom of the convex lens is flat and the peripheral portion has a circumferential surface portion 1704 parallel to the optical axis 1701 of the plano-convex lens. It is preferable to configure the edge 1703 forming the circumferential surface portion of the plano-convex lens to be arranged along the inner wall 1706 of the circumferential wall portion of the top surface of the truncated cone of the base on the silicone gel film 1707 arranged on the top surface of the truncated cone of the base. For example, when a light-emitting member or a phosphorescent member is arranged over the entire surface (excluding the wall surface portion) of the top surface of the truncated cone, it is preferable that the light emitted from the entire surface is evenly accommodated in the plano-convex lens. In that case, if the structure does not have this edge, only a small amount of light from the outermost periphery of the light-emitting member or phosphorescent member is accommodated in the plano-convex lens, and the efficiency is not very good. Therefore, the part is configured to have a thickness by providing an edge, and the amount of light lost at the outermost periphery of the plano-convex lens is reduced. Furthermore, if the plano-convex lens is made of a flexible material such as silicone rubber, it is advantageous to have a certain thickness, since if the outermost periphery becomes too thin, the strength will be weakened and it will be easily damaged by external forces. Furthermore, if the outermost periphery edge of the plano-convex lens is protected by a wall surface provided on the outermost periphery of the upper surface of the base, the protective effect is further increased, which is preferable.
FIG. 17B is also a diagram showing an example of a specific configuration of a plano-convex lens, but shows an example in which the shape of the base on which the plano-convex lens is arranged is cylindrical rather than truncated cone.

In addition, by using silicone as the material for the plano-convex lens, in addition to providing the excellent lens properties unique to silicone, such as weather resistance, heat resistance, cold resistance, corrosion resistance, electrical insulation, and transparency, it also has excellent durability with little deterioration such as clouding caused by ultraviolet rays, etc.

18A is a conceptual diagram for explaining that the incident light becomes a wide angle by the plano-convex lens. As shown in the figure, when a plano-convex lens 1803 is used, the incident angle _S1 1802 of the incident light 1801 from the outside becomes a wider angle than the incident angle _S2 1805 of the incident light 1804 from the outside when a plano-convex lens is not used, which is advantageous for storing the incident light described later.

Furthermore, as shown in FIG. 19A , when plano-convex lens 1903 is used, the reflection angle T ₁ 1902 of reflected light 1901 to the outside is wider than the reflection angle T ₂ 1905 of reflected light 1904 from the outside when no plano-convex lens is used, so the angle of illumination of light to the outside becomes wider, which is effective in reducing the blind spot range required for the attention alert section.
In addition, in Figures 18B and 19B, the truncated cone-shaped base in Figures 18A and 19A above is replaced with a cylindrical base, but it is clear that this difference in shape does not result in any difference in the irradiation effect of the plano-convex lens described above using Figures 18A and 19A.

(An example of a circular silicone gel film with its outermost edge positioned near the outermost edge of the top surface of a truncated cone in the base.)
The silicone gel film in the fence structure with warning portion of this embodiment may be a circular film whose outermost edge is positioned near the outermost circumference of the truncated cone top surface of the base.

Originally, the silicone gel film was intended to adhere a base and a plano-convex lens made of silicone material, and to serve that purpose, it would be sufficient to arrange it in one or more sections on a portion of the truncated cone top surface of the base. However, by making the silicone gel film circular and arranging its outermost edge near the outermost periphery of the truncated cone top surface of the base, the silicone gel film comes into uniform contact with the base of the plano-convex lens. This eliminates any intervening areas of air or moisture between the base of the plano-convex lens and the truncated cone top surface of the base, which not only enhances the reflection effect but also prevents deterioration of the truncated cone top surface of the base and the base of the plano-convex lens. This configuration therefore makes it possible to provide a fence structure with a warning section that is durable and prevents deterioration.

(A configuration in which a flat reflective material, a flat light-storing material, or a flat light-emitting material is provided under the silicone gel film)
In addition to the above-mentioned configuration, the fence structure with warning portion of this embodiment may further comprise one or more of a planar reflective material, a planar phosphorescent material, and a planar self-illuminating material under the silicone gel film that forms the base of the warning portion.

As shown in FIG. 20, the lower layer 2002 of the base silicone gel film 2001 in the warning portion of this embodiment is provided with one or more of a planar reflective material, a planar phosphorescent material, and a planar self-illuminating material.

(Flat reflective material)
The planar reflector is located under the silicone gel film, and is arranged in a planar shape on the top surface of the truncated cone of the base, for example, by spraying titanium oxide or attaching a titanium oxide film. The planar reflector itself, like the reflector arranged on the side surface of the truncated cone of the base, has the property of reflecting light irradiated from the headlights of a car or bicycle, which is a light source at night, in a direction parallel to and opposite to the light source direction, but in this embodiment, the light is diffused at a wide angle and irradiated to the outside by the plano-convex lens arranged on the upper layer of the planar reflector. As a result, the reflected light of the light irradiated from the headlights of a car or bicycle brings its brightness to the peripheral area, which has the effect of reducing the blind spot range required for the attention-attracting part. In addition, the color of the planar reflector is preferably white due to its high reflection efficiency.

(Planar luminous member)
The planar phosphorescent member is located under the silicone gel film and is arranged in a planar shape on the top surface of the truncated cone of the base. The phosphorescent member stores light energy irradiated from the outside and radiates a certain amount of that energy to the outside as light emission. The difference in energy is stored in the phosphorescent member and has the physical property of emitting light even when the light irradiation from the outside is stopped. Generally, phosphorescent members have issues with their brightness and afterglow time, but the plano-convex lens attached on the silicone gel film focuses light at a wide angle, which is advantageous for the phosphorescent function. Conversely, the plano-convex lens irradiates light at a wide angle, which brings the brightness to the peripheral area, thereby having the effect of widely informing the presence of the sign.

(Planar self-illuminating component)
The planar self-illuminating member is located under the silicone gel film and is disposed in a planar manner on the top surface of the truncated cone of the base in a unit-embedded manner. There are single-sided light-emitting members that emit light only from one side and double-sided light-emitting members that emit light from both sides, and the brightness of the light-emitting surface of the single-sided light-emitting member is higher than that of the double-sided light-emitting member. The planar self-illuminating member is, for example, an LED or an organic EL that is automatically turned on at night, and although it requires power from an external source, the required power is small and it is also durable, so it is used in signs that require long-term brightness. The plano-convex lens attached on the silicone gel film diffuses the light at a wide angle and irradiates it to the outside. As a result, the reflected light of the light irradiated from the headlight of a car or bicycle not only returns parallel and in the opposite direction to the light source, but also brings part of the brightness to the peripheral area, which has the effect of reducing the blind spot range required for the phosphorescent body.

(Combination of planar self-illuminating material, planar phosphorescent material, and planar reflective material)
Various effects can be obtained by combining two or more of the above-mentioned planar reflective material, translucent planar light-storing material, opaque planar light-storing material, transparent planar self-illuminating material, and translucent self-illuminating material. Here, the planar reflective material can be used only in the bottom layer, and the planar light-storing material and/or the planar self-illuminating material in the upper layer have the property of light transmission (transparent, translucent). In addition, in the combination of two or more of the above-mentioned planar reflective material-containing materials, the materials are attached to each other via a silicone gel film or silicone gel between them to prevent peeling of the attached parts and to push out air that causes brightness deterioration and prevent its inclusion.

(The upper layer is a transparent double-sided self-illuminating material, the lower layer is an opaque phosphorescent material, and underneath that is a flat reflective material.)
During the day, the upper layer is a transparent double-sided self-illuminating material that transmits sunlight, and the sunlight is efficiently absorbed by the opaque phosphorescent material underneath, emitting light due to phosphorescence at night. When the transparent double-sided self-illuminating material emits light at night, the light from the upper surface of this layer is irradiated onto the road or the like through a plano-convex lens, and the light from the lower surface of this layer is absorbed by the opaque phosphorescent material. Even if the emission of the transparent double-sided self-illuminating material in the upper layer is interrupted, light is emitted due to the phosphorescence accumulated by the emission of the transparent double-sided self-illuminating material before that. Therefore, even if the transparent double-sided self-illuminating material does not emit light during the night, it can be used as a road sign that is bright all night long by only emitting light intermittently.

(The upper layer is a transparent double-sided self-illuminating material, the lower layer is a semi-transparent double-sided phosphorescent material, and the lower layer is a flat reflective material.)
The light emitted from the upper layer transparent double-sided self-illuminating component toward the top is released to the outside through the plano-convex lens, and part of the light directed downward is stored in the phosphorescent component, while the other part passes through the phosphorescent component and is reflected by the planar reflector to again contribute to the phosphorescence of the phosphorescent component, or passes through the phosphorescent component and then through the transparent planar self-illuminating component to be released from the plano-convex lens. In other words, there is relatively little waste of light energy, and as in the previous example, there is no need to supply electricity to the transparent double-sided self-illuminating component all night, so energy consumption can be reduced.

(The upper layer is a translucent flat phosphorescent material, the lower layer is a transparent double-sided flat self-illuminating material, and the lower layer is a reflective material.)
Since the upper layer is a translucent flat luminous material, it can efficiently receive solar energy during the day, particularly solar energy from the plano-convex lens, and at night, it stores light by being irradiated with light from the transparent double-sided flat self-luminous material in the lower layer, and part of the self-luminescence can be radiated to the outside from the plano-convex lens via the translucent luminous layer, thereby improving the brightness compared to when light is simply irradiated from the luminous material at night.

(The upper layer is a translucent flat phosphorescent material, the lower layer is a transparent double-sided flat self-illuminating material, and the lower layer is an opaque single-sided light-emitting phosphorescent material.)
This is the above example, but with a one-sided light-emitting phosphorescent material instead of the lower layer reflective material. The reflective material in the above example may be the bottommost layer. The difference from the above example is that a one-sided light-emitting phosphorescent material is placed where the reflective material is. Instead of simply reflecting, light energy is stored in the phosphorescent material. In addition to the energy storage efficiency of the translucent phosphorescent material in the top layer, energy is also stored in the lower layer, so the energy storage efficiency can be increased compared to when energy is stored in a single layer.

(The planar light-storing member is made of a light-storing material having a silicone resin or an elastic silicone rubber as a base material.)
In addition to the above configuration, the warning part in this embodiment may further include a planar phosphorescent member made of a phosphorescent material with silicone resin or elastic silicone rubber as a base material under the silicone gel film as a base material. This makes it possible to avoid peeling of the attached part at the boundary surface due to thermal expansion or thermal contraction, since the silicone gel film and the planar phosphorescent member are made of a common material.

Luminous materials with silicone resin or elastic silicone rubber as the base material are made by mixing granular luminous material into transparent silicone resin or elastic silicone rubber, and deterioration can be prevented due to the excellent weather resistance of silicone. In addition, because it is made of the same silicone material as silicone gel film, peeling of the adhesive part at the interface due to thermal expansion or thermal contraction can be avoided. Examples of luminous materials include aluminates.

The rest of the structure is the same as that of the silicone gel film with a planar phosphorescent member underneath.

(A reflective layer is provided under the planar light-accumulating member to reflect light that has passed through the planar light-accumulating member)
In addition to the above configuration, the attention drawing section in this embodiment may further have a reflective layer below the planar light-accumulating member, and may be configured to reflect light transmitted through the planar light-accumulating member. This configuration makes it possible to improve the light-accumulating function.

As shown in FIG. 21, the warning portion in this embodiment has a planar phosphorescent material in the lower layer 2102 of the base silicone gel film 2101, and a reflective layer in the lower layer 2103 of that.

The reflective layer improves the phosphorescence function by reflecting the light (electromagnetic waves) that has passed through the planar phosphorescent member and emitting the reflected light back to the planar phosphorescent member, so this configuration can improve the phosphorescence function of the planar phosphorescent member.

(Configuration with silicone resin coating layer when a flat reflective material is provided under the silicone gel film)
In addition to the above configuration, the attention-drawing portion in this embodiment may further have a silicone resin coating layer when a flat reflective material is provided under the base silicone gel film.

The silicone resin coating layer can be formed as a thin and uniform silicone layer that conforms to the shape of the planar reflective material. This improves adhesion between the planar reflective material having the silicone resin coating layer and the silicone gel film.

(At least the entire plano-convex lens and the boundary between the plano-convex lens and its underlying structure are covered with a glass coating layer.)
In addition to the above-mentioned configuration, the warning portion that constitutes the fence structure with warning portion of this embodiment may further be configured so that at least the entire plano-convex lens and the boundary between the plano-convex lens and its underlying structural portion (synonymous with base; the same applies below) are covered with a glass coating layer.

Figure 22 is a perspective view showing that the entire plano-convex lens 2201 in the warning portion of the fence structure with warning portion of this embodiment, and the boundary between the plano-convex lens and its underlying structure portion 2202, are covered with a glass coating layer 2203 made of a glass material.

The glass coating layer has the effect of improving weather resistance and dirt resistance by protecting the surface it covers. Due to the affinity between glass and silicone, the effect lasts for a long time. The glass coating is configured to cover all or part of the surface of the plano-convex lens with a layered member made of glass to protect the entire plano-convex lens and the boundary between the plano-convex lens and its underlying structure from scratches, water, and dust. This configuration can suppress the deterioration of the phosphorescent body of the attention-attracting part for a long period of time.
Although not shown, the truncated cone-shaped base 2202 in FIG. 22 may be cylindrical, as described with reference to FIG. 16A etc.

(Configuration in which silicone gel film is a double-sided gel film)
In the fence structure with warning parts of this embodiment as well, the silicone gel film may be a double-sided gel film.

As mentioned above, the silicone gel film is a double-sided silicone film with silicone gel on both sides. In addition to the properties of silicone such as weather resistance, heat resistance, cold resistance, corrosion resistance, electrical insulation, and transparency, the silicone gel has excellent adhesiveness and adhesion properties. First, the silicone gel film is attached to the bottom of a plano-convex lens made of silicone material by peeling off the separator on one side to expose the silicone gel, and the air is removed thoroughly. Next, the separator on the other side is peeled off to expose the silicone gel, and the silicone gel is placed on the top surface of the truncated cone of the base and attached, preventing air from entering. Since the plano-convex lens and the silicone gel film are made of the same material, they have a high affinity, and the silicone gel film flexibly follows the thermal expansion and thermal contraction of the plano-convex lens, preventing the attached part from peeling off.

The specific configuration of the double-sided gel film used in this embodiment may be the same as that described in Example 3.

(The top surface of the base has a circumferential wall on its periphery, and the edge of the plano-convex lens is disposed along the inner wall side of the circumferential wall.)
Furthermore, in addition to the above configuration, the warning portion in the fence structure with warning portion of this embodiment may be configured so that the top surface of the base has a circumferential wall portion on its periphery, and the plano-convex lens has its edge positioned along the inner wall side of the circumferential wall portion.

As shown in FIG. 23, a top surface 2302 of a base 2301 has a circumferential wall portion 2304 around its peripheral edge 2303, and an edge 2306 of a plano-convex lens 2305 is disposed along the inner wall side of the circumferential wall portion.
Although not shown, the truncated cone-shaped base 2301 in FIG. 23 may be cylindrical, as described with reference to FIG. 16A etc.

24 is a plan view of the base and the plano-convex lens. As shown in the figure, the top surface 2402 of the base 2401 has a circumferential wall portion 2404 on its peripheral edge 2403, and an edge 2406 of the plano-convex lens 2405 can be disposed along the inner wall side of the circumferential wall portion.
Although not shown, the truncated cone-shaped base 2401 in FIG. 24 may be cylindrical, as described with reference to FIG. 16A etc.

The plano-convex lens is attached to the top surface of the base with a silicone gel film, but a circumferential wall is formed around the periphery of the top surface of the base, and the edge of the plano-convex lens is positioned along the inner wall side of the circumferential wall. This means that even if a strong lateral force is applied to the marking device, the circumferential wall around the periphery of the top surface of the base supports the edge of the plano-convex lens, preventing the plano-convex lens from peeling off from the truncated cone top surface of the base.

(The edge of the plano-convex lens has a circumferential surface portion parallel to the optical axis of the plano-convex lens, and the height of the circumferential surface portion is equal to or less than the height of the inner wall of the circumferential wall.)
In addition to the above-mentioned configuration, the warning portion in the fence structure with warning portion of this embodiment may be further configured so that the edge of the plano-convex lens has a circumferential surface portion parallel to the optical axis of the plano-convex lens, and the height of the circumferential surface portion is less than or equal to the inner wall height of the circumferential wall.

17A, the height of the inner wall 1706 of the circumferential wall portion at the periphery 1708 of the top surface 1707 of the base 1705 is _h2 , and the edge 1703 of the plano-convex lens 1702 has a circumferential surface portion 1704 parallel to the optical axis 1701 of the plano-convex lens, and the height of the circumferential surface portion is _h1 . Here, _h1 is configured to be equal to or smaller than _h2 .

The optical axis of a plano-convex lens is a straight line that is perpendicular to the convex portion of the plano-convex lens and passes through its center, and coincides with the axis of rotational symmetry of the convex portion of the plano-convex lens. As a result, the circumferential surface portions parallel to the optical axis have the same height.

＜Overview＞
This embodiment relates to a method for manufacturing the fence structure with a warning part described in the third embodiment and the like.

<Processing flow>
FIG. 25 is a diagram showing an example of a process flow relating to the manufacturing method of the fence structure with a warning part of this embodiment.

That is, as shown in the figure, in the manufacturing method of the warning unit of this embodiment, first, in base substrate preparation step S2501, a base substrate is prepared.

Next, in the reflective layer placement step S2502, a reflective layer is placed on the base substrate.

Next, in gel adhesive layer placement step S2503, a gel adhesive layer is placed on the reflective layer. Although not shown, it is desirable to have a step between this step S02503 and step S2505 described below of rubbing the surface of the placed gel adhesive layer with, for example, the side of a cylindrical rod. This removes any air bubbles between the reflective layer and the gel adhesive layer and completely adheres the two layers together, creating a so-called vacuum adhesion state, which allows for strong fixation without the use of adhesive. It can also be said that this step makes the surface of the gel adhesive layer smoother, making it easier to place the phosphorescent silicone body described below.

Next, in step S2504 for preparing a phosphorescent silicone body, a phosphorescent silicone body is prepared by dispersing phosphorescent material in silicone. Note that the order of this step S2504 and steps S2501 to S2503 may be reversed.

Next, in step S2505 of placing the phosphorescent silicone body, the prepared phosphorescent silicone body is placed on the gel adhesive layer. Although not shown, it is desirable to have a step between this step S2505 and the next step S2506 of rubbing the surface of the dome-shaped phosphorescent silicone body that has been placed, for example by wrapping it in a cloth. The purpose of this step is the same as the purpose of the step of rubbing the surface of the gel adhesive layer described above.

Next, in the glass coating layer coating step S2506, at least the phosphorescent silicone body is coated with a glass coating layer.

The above-mentioned phosphorescent silicone body preparation step S2504 may further include the following sub-steps as shown in FIG. 26. First, in sub-step S2601 of inserting uncured phosphorescent silicone into a mold, phosphorescent silicone, which is silicone with uncured phosphorescent material dispersed therein, is poured into a mold. The shape of the mold can vary depending on the shape of the phosphorescent silicone body. For example, if the phosphorescent silicone body is dome-shaped, a mold with a dome-shaped hollowed-out portion is used. Next, in sub-step S2602 of curing, the phosphorescent silicone poured into the mold is cured. Furthermore, in sub-step S2603 of removing from mold, the cured phosphorescent silicone is removed from the mold. Note that the processing in these phosphorescent silicone body preparation steps may be performed before the base substrate preparation step, rather than after the gel adhesive layer arrangement step.

In addition, although not shown in the figures, the phosphorescent silicone body preparation step may further include a leaving sub-step prior to the curing sub-step in which the poured pre-cured phosphorescent silicone is left to allow the phosphorescent material dispersed in the pre-cured silicone to naturally settle, causing the dispersion density of the phosphorescent material to vary within the silicone.

Furthermore, although not shown in the figures, there may be a further step prior to the curing sub-step in which the poured pre-cured phosphorescent silicone is left to stand, allowing the phosphorescent material dispersed in the pre-cured silicone to naturally settle, resulting in a different dispersion density within the silicone.

＜Effects＞
According to the invention of this embodiment, it is possible to provide a fence structure with a warning portion that has excellent weather resistance and stain resistance.

＜Overview＞
This embodiment is basically the same as the manufacturing method of a fence structure with a warning part explained in embodiment 10, but in the leaving sub-step, the mold into which the uncured phosphorescent silicone has been poured is rotated and/or rocked. This provides a manufacturing method for a fence structure with a warning part having a phosphorescent silicone body in which the density of the phosphorescent material on the outer surface side is greater than the density of the phosphorescent material on the central side explained in embodiment 4.

<Processing flow>
As described above, in order to form a phosphorescent silicone body, in the leaving sub-step of the phosphorescent silicone body preparation step, the phosphorescent silicone, which is silicone in which the phosphorescent material before hardening is dispersed, is poured into a mold and left to harden. In this case, in order to make the density of the phosphorescent material on the outer surface side greater than the density of the phosphorescent material on the central portion side, in the leaving sub-step, the mold into which the phosphorescent silicone before hardening is poured may be rotated around the central axis of the mold as the axis of rotation. This rotation allows the phosphorescent material to be distributed more on the left and right surface sides of the phosphorescent silicone body by centrifugal force. In addition, by leaving the phosphorescent silicone body with the top side facing down, the phosphorescent material can be distributed more on the top surface side. Furthermore, the distribution can be changed by adjusting the rotation speed, rotation time, and leaving time. In addition, the distribution of the phosphorescent material in the phosphorescent silicone body can be adjusted by applying appropriate rocking.

＜Effects＞
According to this embodiment, since the phosphorescent material can be distributed more toward the surface side of the phosphorescent silicone body, the luminescence brightness of the phosphorescent silicone body can be relatively increased.

＜Overview＞
This embodiment is basically the same as the manufacturing method for a fence structure with a warning part described in Example 10 etc., but further includes a joining step and a pressure welding assembly step as steps for attaching the warning part to the pole body.

<Processing flow>
FIG. 27 is a diagram showing an example of a process flow relating to the manufacturing method of the fence structure with a warning part of this embodiment.

As shown in the figure, the manufacturing method of this embodiment includes steps similar to steps S2501 to S2506 shown in FIG. 25 (steps S2701 to S2706 in the figure), as well as a joining step S2707 and a pressure welding assembly step S2708.

The joining step is a step of joining the attention calling part (if the insertion mounting part is included as a component, the part excluding the insertion mounting part) to the insertion mounting part for inserting it into the hollow pole. One example of the joining method is the same as that described in Example 1, in which a screw hole penetrating from top to bottom is provided in the base substrate of the attention calling part, and a screw hole is also provided in the corresponding position of the insertion mounting part, and the phosphorescent body is screwed integrally to the base substrate and the insertion mounting part using a screw attached to the bottom surface of the phosphorescent body.

Next, in the pressure fitting step, the insertion mounting portion of the warning part with insertion mounting portion, which was provided in the joining step, is pressure fitted into the cavity of the pole. One example of pressure fitting, as also described in Example 1, is to attach a leaf spring with a protruding portion to the bottom surface of the insertion mounting portion, and then insert this into the tubular portion (hollow pole) at the top of the pole body. This causes the leaf spring to press against the inner wall of the hollow pole due to the biasing force of the protruding portion of the leaf spring, thereby locking the insertion mounting portion into the hollow pole.

In order to make this locking more reliable, an adhesive application step may be included before the pressure fitting step, in which adhesive is applied to the outer surface of the inner insertion attachment part. Also, instead of or in addition to the adhesive application step, a screw hole installation step may be included before the pressure fitting step, in which screw holes are provided at the side surface of the pole body and the leaf spring or the corresponding positions of the inner insertion attachment part, and a screw fastening step may be included after the pressure fitting step. Alternatively, instead of or in addition to the adhesive application step and/or the screw hole installation step/screw fastening step, a step installation step may be included before the pressure fitting step, in which a step is provided on the inner wall of the hollow pole, and the pressure fitting step may include a step abutment sub-step in which the tip of the protruding part of the leaf spring is abutted against the step.

(others)
In this embodiment, it is essential that the attention drawing unit includes a base substrate, a phosphorescent silicone body, a reflective layer, and a gel adhesive layer as described in embodiment 3. On the other hand, as a difference from this embodiment, the attention drawing unit is not limited to that described in embodiment 3, and may include steps similar to the above-mentioned steps S2707 and S2708 as a process for attaching the attention drawing unit to the pole body, under the premise that it is sufficient that the attention drawing unit uses a phosphorescent material in a part of the dome part as described in embodiment 1.

An example of the overall process in such a case is the steps of (1) forming a warning part containing a phosphorescent material in at least a part of a dome-shaped dome (Step 01), (2) joining the warning part formed in Step 01 to an insertion mounting part for inserting into a hollow pole (Step 02), and (3) crimping and fitting the insertion mounting part of the warning part with insertion mounting part provided in Step 02 into the hollow of the pole (Step 03).

As sub-steps of step 01, the following may be included as described in Example 9: (1) forming a warning portion having a configuration including a plano-convex lens, for example, preparing a base made of a metal material in the shape of a truncated cone (step 011); (2) arranging a reflective material on the side of the truncated cone of the base prepared in step 011 (step 012); (3) arranging a silicone gel film on the top surface of the truncated cone of the base prepared in step 011 (step 013); and (4) arranging a plano-convex lens made of a silicone material on the silicone gel film arranged on the top surface of the truncated cone of the base in step 013, with its edge aligned with the edge of the top surface of the truncated cone of the base (step 014).

＜Effects＞
According to the present embodiment, the attention-calling part is securely attached to the pole body, making it difficult for the attention-calling part to fall off the pole body even during a disaster, etc., which contributes to proper attention-calling. It also contributes to preventing theft, such as removing the attention-calling part from the pole body and taking it away.
