  The road marking ring 10 includes an embedded cylinder part 30 embedded in the annular groove part M1 and a bulging arc part 20 integrally formed on the upper end part of the embedded cylinder part 30. Further, the bulging arc portion 20 includes a linear reflecting member 40 and a linear light emitting member 50 which will be described later, and the bulging arc portion 20 excluding the linear reflecting member 40 and the linear light emitting member 50 is provided. The main body 21 and the embedded cylinder part 30 are integrally formed (see FIG. 8). A main body 11 of the road marking ring 10 which is an integrally molded product is a molded product of an elastomer (for example, a soft vinyl chloride resin) compounded with a photocatalyst (for example, titanium oxide), for example, white, orange, blue, It is colored in other vivid colors.

  The embedded cylinder portion 30 has a shape that matches the internal shape of the annular groove portion M1 described above. That is, the embedded cylinder portion 30 includes a cylindrical portion 31 that fits in the deep groove portion of the annular groove portion M1, and a flange portion 32 that protrudes laterally from the outer peripheral surface of the upper end of the cylindrical portion 31 and fits in the shallow groove portion of the annular groove portion M1. And have. Further, in order to facilitate the insertion operation into the annular groove M1, the lower end portion of the cylindrical portion 31 has a tapered conical shape. When the road marking ring 10 is fitted into the annular groove M1, the upper surface of the flange 32 and the pavement surface S1 are configured to be substantially flush with each other. In addition, it is difficult to remove the road marking ring 10 installed on the pavement surface S1 by installing the embedded cylindrical part 30 having a cylindrical shape in the annular groove M1. In addition, the deep groove portion and the shallow groove portion are provided in the annular groove portion M1, and the cylindrical portion 31 and the flange portion 32 are respectively fitted to the annular groove portion M1, thereby further preventing the road marking ring 10 from coming off.

  As shown in FIGS. 2 and 3, a plurality of wire holding grooves 33 are formed on the outer peripheral surface and the inner peripheral surface of the embedded cylinder part 30. The wire holding groove 33 has an arcuate cross-sectional shape that extends in the axial direction of the embedded cylinder portion 30 and opens downward. Further, the wire holding groove 33 is configured to gradually become shallower from the lower end portion of the embedded cylinder portion 30 toward the upper end portion.

  Specifically, the plurality of wire rod holding grooves 33 formed on the outer peripheral surface of the embedded tube portion 30 are arranged at equal intervals in the circumferential direction of the embedded tube portion 30, and the central axis thereof is the lower end of the embedded tube portion 30. It inclines so that it may leave | separate from the central axis of the embedded cylinder part 30 as it goes to an upper end part from a part.

  On the other hand, as shown in FIG. 2, the plurality of wire holding grooves 33 formed on the inner peripheral surface of the embedded cylinder portion 30 are arranged so as to be shifted in the circumferential direction with respect to the wire holding grooves 33 formed on the outer peripheral surface. The central axis is inclined so as to approach the central axis of the embedded cylinder part 30 as it goes from the lower end part to the upper end part of the embedded cylinder part 30.

  These wire rod holding grooves 33 have a dominant arc or circle in at least part of the axial direction, and hold the linear member L1 inserted from the lower end of the wire rod holding groove 33 (see FIGS. 3 and 4). It is possible to do. The linear member L1 has a circular cross section, and when the linear member L1 is mounted in the wire rod holding groove 33, a part of the outer peripheral surface of the linear member L1 protrudes from the wire rod holding groove 33 and the outer periphery of the embedded cylinder portion 30. It protrudes from the surface or inner peripheral surface. When the fitting between the annular groove part M1 and the buried cylinder part 30 is loose and the road marking ring 10 is rattled, the annular groove part M1 and the buried cylinder part 30 are fitted by attaching the linear member L1 to the buried cylinder part 30. The backlash of the road marking ring 10 can be eliminated. The linear member L1 is preferably an elastomer.

  Here, as described above, the wire holding groove 33 becomes shallower from the lower end portion toward the upper end portion. Therefore, when the embedded cylindrical portion 30 with the linear member L1 is inserted into the annular groove portion M1, the wire holding groove 33 is formed. It is possible to prevent the lower end portion of the shaped member L1 from being caught on the edge portion of the annular groove portion M1, and the fitting operation of the road marking ring 10 to the annular groove portion M1 can be performed smoothly.

  The bulging arc portion 20 of the road marking ring 10 extends in the circumferential direction of the embedded cylinder portion 30 and has a notch portion 22 for draining water (see FIGS. 1 and 9) in a part of the circumferential direction C. It has a letter shape. Further, as shown in FIG. 3, the bulging arc portion 20 projects radially inward of the embedded cylinder portion 30, and in a state where the road marking ring 10 is fitted in the annular groove portion M1, as shown in FIG. The lower surface of the bulging arc portion 20 is superimposed on the pavement surface S1, and the entire bulging arc portion 20 bulges upward from the pavement surface S1. On the other hand, the upper surface of the notch 22 is substantially flush with the pavement surface S1, so that rainwater and dust entering the inside of the bulging arc portion 20 are smoothly discharged.

  As shown in FIG. 3, the cross section of the bulging arc portion 20 has a gentle mountain shape (saddle shape). A plurality of block-shaped protrusions 23 are formed at the summit portion of the bulging arc portion 20. Further, the outer peripheral surface of the bulging arc portion 20 has a retroreflective property on the outer peripheral surface inclined downward from the summit toward the outer side in the radial direction and the inner peripheral surface inclined downward from the summit in the radial direction. The linear reflection part 24 (refer FIG. 1) which has is provided. The linear reflecting portion 24 continuously extends over a range of about 270 degrees around the central axis of the road marking ring 10.

  The linear reflecting portion 24 is configured by fitting a linear reflecting member 40 (see FIG. 3), which is a separate part from the main body 11 of the road marking ring 10, into a reflecting member accommodation groove 26 formed in the bulging arc portion 20. Has been. The linear reflecting member 40 has a structure in which a reflective tape having a retroreflective property (corresponding to the “reflecting material” of the present invention) is wound around the outer peripheral surface of an elastomer wire having a circular cross section in a winding shape. . On the other hand, as shown in FIG. 6, the reflecting member accommodating groove 26 has a groove shape with an arcuate cross section, and extends in a curved manner along the outer peripheral surface and inner peripheral surface of the bulging arc portion 20 ( (See FIG. 7). The linear reflecting member 40 may be fixed with an adhesive. Further, the wire as the core of the linear reflecting member 40 and the linear member L1 used by being mounted on the embedded cylinder portion 30 may have the same diameter, and may be manufactured by separating them from common linear parts. .

  As shown in FIG. 1, a linear light emitting portion 25 having fluorescence or phosphorescence is provided on the outer peripheral surface and the inner peripheral surface of the bulging arc portion 20. The linear light emitting unit 25 extends in a concentric arc shape in parallel with the linear reflecting unit 24. Further, the linear light emitting portion 25 continuously extends over the same range as the linear reflecting portion 24 in the circumferential direction of the bulging arc portion 20, that is, about 270 degrees around the central axis of the road marking ring 10. ing.

  The linear light emitting portion 25 is formed by forming a linear light emitting member 50 (see FIG. 3) containing a fluorescent or phosphorescent light emitting agent and shaped in an arc shape on the bulging arc portion 20 (main body 21). The light emitting member accommodating portion 27 is fitted (see FIG. 5). The linear light emitting member 50 is made of, for example, an elastomer.

  As shown in FIG. 4, the linear light emitting member 50 protrudes above the reflecting member housing groove 26 and overlaps the linear reflecting member 40. More specifically, as shown in FIG. 6, the upper surface of the linear light emitting member 50 is an inclined surface 51 that constitutes the linear light emitting unit 25. An arc-shaped concave curved surface 52 corresponding to the cross-sectional shape of the linear reflective member 40 is formed on a portion of the lower surface of the linear light emitting member 50 that protrudes above the reflective member housing groove 26. An uneven portion 53 is formed adjacently. The inclined surface 51, the concave curved surface 52, and the uneven portion 53 are continuous over the entire length of the linear light emitting member 50.

  On the other hand, the light emitting member accommodating portion 27 is formed on the peak side of the bulging arc portion 20 with respect to the reflecting member accommodating groove 26 and extends in parallel with the reflecting member accommodating groove 26 (see FIG. 7). The light emitting member accommodating portion 27 has an uneven portion 28 extending over the entire length thereof, and the uneven portion 28 and the uneven portion 53 of the linear light emitting member 50 are engaged with each other (see FIG. 6). By causing the linear light emitting member 50 to overlap the linear reflective member 40 accommodated in the reflective member accommodating groove 26, the linear reflective member 40 can be prevented from coming off from the reflective member accommodating groove 26. Further, since the linear reflecting member 40 can be prevented from being stepped on directly by a vehicle or a pedestrian, the reflection performance of the linear reflecting member 40 can be maintained for a long period of time. The linear light emitting member 50 may be fixed by an adhesive or welded to the main body 21 of the bulging arc portion 20 (specifically, vibration welding).

  The configuration of the present embodiment is as described above. When the road marking ring 10 is installed on the pavement surface S1, first, an annular groove M1 is formed on the pavement surface S1 with a rotary excavation tool. Next, the excavation waste in the annular groove M1 is removed, and the road marking ring 10 is fitted into the annular groove M1 by trial. At this time, when the road surface marking ring 10 rattles in the annular groove portion M1, the linear member L1 is attached to the embedded tube portion 30 to fit the embedded tube portion 30 and the annular groove portion M1. Further, when the shallow groove portion of the annular groove portion M1 is too deep and the bulging arc portion 20 is buried in the shallow groove portion, a plate-like spacer (not shown) is sandwiched between the shallow groove portion and the flange portion 32. Thus, the height is adjusted so that the bulging arc portion 20 bulges above the pavement surface S1.

  Next, the road marking ring 10 is once removed, and a filler for filling the gaps between the road marking ring 10 and the annular groove M1 and the pavement surface S1 is injected into the annular groove M1. Finally, the road marking ring 10 is fitted into the annular groove M1. At this time, it arrange | positions so that the notch part 22 may become the lower side of the gradient of pavement surface S1. For example, the road marking ring 10 is arranged so that the cutout portion 22 is on the downhill side on the pavement surface S1 of the slope. Further, since a general paved road is provided with a cross slope for drainage, the road marking ring 10 is arranged so that the notch 22 is below the cross slope. This completes the installation of the road marking ring 10.

  When the road marking ring 10 is embedded and installed in the annular groove portion M1, the bulging arc portion 20 protrudes above the pavement surface S1. The bulging arc portion S1 has a C-shape in plan view, and the central portion surrounded by the bulging arc portion S1 is a recess (see FIG. 9). However, it can be used to prevent slipping. Further, since the road marking ring 10 is installed by embedding the cylindrical buried cylinder 30 in the annular groove M1 formed on the pavement surface S1, it is difficult to remove the road marking ring 10 installed on the pavement surface S1. can do. Moreover, since the main body 11, the linear reflecting member 40, and the linear light emitting member 50 of the road marking ring 10 are made of elastomer, they are not easily damaged even if they are repeatedly stepped on. It will not be a hindrance.

  When light is applied to the road marking ring 10 (the bulging arc portion 20) at night or in a dark place (such as a tunnel or an underground parking lot), the light is retroreflected by the linear reflection portion 24. For example, when the vehicle headlight is irradiated on the linear reflector 24, the vehicle driver can visually recognize the reflected light, and the visibility of the road marking ring 10 can be ensured even at night or in a dark place. . Moreover, since the linear reflection part 24 is provided in both the outer peripheral surface and inner peripheral surface of the bulging circular arc part 20, and is extended in circular arc shape along the circumferential direction, the side of the bulging circular arc part 20 is provided. It is possible to retroreflect light from all directions such as upward and obliquely upward. For example, even when light is irradiated from the outer peripheral surface of the bulging arc portion 20 from the side of the cutout portion 22 (below the paper surface in FIG. 1), it is provided along the inner peripheral surface of the bulging arc portion 20. Since the light can be retroreflected by the linear reflecting portion 24, the light from all directions around the bulging arc portion 20 can be retroreflected. As a result, the road marking ring 10 can be visually recognized from all directions around the road marking ring 10 and, at the time of installation on the pavement surface S1, it is possible to save time and effort for fine angle adjustment in consideration of the incident direction of light.

  If the linear light emitting part 25 provided in the road marking ring 10 has fluorescence, the linear light emitting part 25 can be caused to emit fluorescent light by the light (ultraviolet rays) irradiated to the linear light emitting part 25, in particular. It is possible to improve the visibility in a dim time zone at dawn or evening, or in a dim place. Moreover, if the linear light emission part 25 has a luminous property, the energy of the light (ultraviolet light) of sunlight and a lighting fixture (for example, a fluorescent lamp, a black light) is stored in the linear light emission part 25, and it makes it light-emit. The visibility of the road marking ring 10 can be ensured even in the dark at night or during a sudden power failure. And since the linear light emission part 25 is extended in parallel with the linear reflection part 24 on both the outer peripheral surface and internal peripheral surface of the bulging circular arc part 20, similarly to the linear reflective part 24, the bulging circular arc part The light emission of the linear light emitting unit 25 can be visually recognized from all directions around 20. Thereby, the visibility of the road marking ring 10 at night or in a dark place is further improved.

  Moreover, since the main body 11 of the road marking ring 10 is colored in white, orange, blue, and other clear colors, the visibility of the road marking ring 10 in the daytime is improved and the decorativeness is improved. Moreover, since the main body 11 of the road marking ring 10 is made of an elastomer compounded with a photocatalyst, the dirt attached to the surface of the bulging arc portion 20 is decomposed or suppressed by the antifouling action of the photocatalyst. Can do. Further, even if the surface of the bulging arc portion 20 is worn away by friction with the tire or the like, a new photocatalyst is exposed from the inside, so that the antifouling action can be maintained for a long time. Furthermore, since the main body 11 of the road marking ring 10 has appropriate toughness, it has an excellent anti-slip effect on the tire and can reduce the impact when stepped on.

  If the road marking ring 10 of the present embodiment is provided on, for example, a road center line, an outer line, a pedestrian crossing, a stop line, or a parking lot demarcation line, the presence thereof is clearly shown to the driver at night or in a dark place. can do. Moreover, since the unevenness | corrugation by the bulging circular arc part 20 can be formed in pavement surface S1, not only a slip prevention effect but alerting to the driver by vibration can be performed.

For example, it may be an ellipse, an ellipse, or a C-shape (horse-shoe shape) in which a part of the oval is cut out in the circumferential direction.

  (11) The road marking ring 10 according to the present embodiment is installed not only on an outdoor concrete or asphalt pavement surface S1, but also on an indoor floor (for example, a warehouse or factory floor) or an external floor (for example, an entrance approach). May be.

  (12) As in the present embodiment, the photocatalyst is compounded in the main body 11 of the road marking ring 10 and the linear light emitting portion 25 (line) is formed on one or both of the outer peripheral surface and the inner peripheral surface of the bulging arc portion 20. If the road marking ring 10 provided with a light-emitting member 50) is used by irradiating it with black light at night, the linear light-emitting part 25 can emit light in the dark, and even at night, in the daytime. The antifouling action of the photocatalyst can be exhibited.

  (13) In the above-described embodiment, the linear light emitting member 50, which is a separate part from the main body 11 of the road marking ring 10, is configured to be fitted into the main body 11, but the road surface is made of an elastomer compounded with a fluorescent pigment or a phosphorescent pigment. The main body 11 of the marking ring 10 may be formed. If it does in this way, the whole surface of the bulging circular arc part 20 can be made to shine, and the visibility at night will improve more.

[Reference example]
10 and 11 show a road marking ring 100 as a reference example that is not included in the technical scope of the present invention but has the same effect as the present invention. This road marking ring 100 is obtained by removing the linear reflecting portion 24 (linear reflecting member 40) and the linear light emitting portion 25 (linear light emitting member 50) from the road marking ring 10 of the above embodiment. Is the same as the road marking ring 10 of the above embodiment. When the road marking ring 100 is installed by being fitted into the annular groove M1 of the pavement surface S1, the C-shaped bulge arc portion 20 in plan view protrudes above the pavement surface S1, and the bulge arc portion 20 Since the central part surrounded by is a recess, it does not slide like a conventional road-shaped road fence, but rather can be used for slip prevention. By the way, if the road marking ring 100 of the present reference example is colored in a clear color such as white, orange, and blue with a pigment, the visibility in the daytime is improved, but there is a problem that dirt is easily noticeable. On the other hand, when the road marking ring 100 is molded with an elastomer compounded with a photocatalyst, it is possible to prevent the occurrence of dirt and slime compared to the case where no photocatalyst is added, and the road marking ring is used over a long period of time. 100 can be kept clean. Specifically, the road marking ring 100 formed by compounding 2-5% by weight of titanium oxide with soft vinyl chloride resin is more soiled than the road marking ring 100 containing no titanium oxide. It was difficult, and field tests confirmed that the antifouling action increased with the increase in titanium oxide. Moreover, if the road marking ring 100 is formed with an elastomer compounded with a fluorescent pigment or a phosphorescent pigment, the entire surface of the bulging arc portion 20 can be illuminated, and visibility at night is further improved.
