  However, even with a self-luminous delineator using a transparent pipe, there is a possibility that the snow may adhere to a part of the transparent pipe and the visibility may be deteriorated under a snowstorm where the snow is blown heavily. In particular, in the case of a vertically long cylindrical transparent pipe, as shown in FIG. 10, there is a tendency for a single row of snow to form at the front end position of the pipe with respect to the snow blowing direction, that is, at the center of the pipe outer periphery with respect to the snow blowing direction. In the self-luminous delineator disclosed in Patent Document 1, the light emitters arranged in a vertical line are hidden by snow and there is a concern that the visibility may be significantly reduced.

The present invention has been created in order to solve these problems in view of the above-described circumstances, and a plurality of the present invention is installed along the road to guide the line of sight to the driver of a passing vehicle. A light-emitting delineator comprising a vertically long cylindrical transparent pipe and a light-emitting part incorporated in the transparent pipe. The light-emitting part is arranged in the vertical direction in the center of the transparent pipe and emits light. A plurality of light emitters that emit light toward the left and right outer sides, and a pair of left and right reflectors that are disposed at both left and right ends of the transparent pipe and reflect the light emitted by the light emitters forward. Features. In this way, two vertical rows of light are emitted from the left and right ends of the transparent pipe toward the front, so that even if a single row of vertical snowfall occurs at the center of the left and right sides of the pipe periphery under circumstances such as snowstorms. Both vertical light emission are not hidden by snowfall. As a result, the visibility required for the self-luminous delineator can be ensured even in a snowy state, and the driver's line of sight can be guided. In addition, the two vertical rows of light are emitted through the reflectors arranged at the left and right ends of the transparent pipe, so that the two vertical rows of light are emitted compared to the case where the light emitters are arranged at the left and right ends of the transparent pipe. The light emission position can be as close as possible to the left and right ends of the transparent pipe. As a result, it is possible to widen the left and right intervals of the light emission in the two vertical rows as much as possible, and to further reduce the possibility that both the light emission in the two vertical rows are hidden by snowfall.
The reflector is configured integrally with a light emitter case that supports a plurality of light emitters. In this way, since the reflector and the light emitter case can be integrally incorporated in the transparent pipe, not only the assembling property of the self-luminous delineator is improved, but also the irradiation direction can be easily adjusted.
Further, the light emitter case includes a plurality of left direction light emitter support portions that support a left direction light emitter and a plurality of right direction light emitter support portions that support a right direction light emitter. In addition, the left-side illuminating light-emitting body support part and the right-side illuminating light-emitting body support part are formed by alternately shifting the positions in the vertical direction. In this way, the efficiency of arrangement of the light emitters in the light emitter case is improved, so that not only the light emitter case can be reduced in size, but also a necessary space (such as a wiring space) inside the light emitter case can be easily secured. be able to.
Further, the reflector is formed of a mirror-finished metal plate. If it does in this way, since the process of sticking a reflective film etc. becomes unnecessary, manufacturing cost can be reduced.
Moreover, the said reflector is comprised by sticking a reflective film on a base material, It is characterized by the above-mentioned. If it does in this way, a reflector can be constituted using a base material which consists of arbitrary materials.

  Next, embodiments of the present invention will be described with reference to the drawings. In FIG. 1 to FIG. 9, reference numeral 1 denotes a self-luminous delineator that is erected along a road and guides the line of sight of a driver of a passing vehicle. An upper cap 3, a lower cap 4, a light emitting unit 5 and a solar cell unit 6 are provided.

  The transparent pipe 2 is made of a vertically long cylindrical resin tube having an upper portion and a lower portion opened. For example, a polycarbonate cylindrical tube is used in a vertical direction. Such a vertically long cylindrical transparent pipe 2 can effectively prevent snow from adhering to the outer peripheral surface, and is therefore extremely advantageous when installed in an area where there is a large amount of snowfall. However, under circumstances such as snowstorms where snow blowing is intense, snow may adhere to a part of the outer periphery of the transparent pipe 2 as well, especially in the case of the vertically long cylindrical transparent pipe 2, the position of the pipe front end with respect to the direction of snow blowing, That is, there is a tendency that a single vertical snowfall occurs at the left and right central positions on the outer periphery of the pipe with respect to the snow blowing direction.

  The upper cap 3 and the lower cap 4 are cap members for covering the upper opening and the lower opening of the transparent pipe 2, and are formed of, for example, an aluminum casting or an opaque resin. The lower cap 4 not only functions as a cap member that covers the lower opening of the transparent pipe 2 but also serves as an attachment member that is fixed at the installation location. Specifically, the lower cap 4 of the present embodiment has a fitting recess 4a that is rotatably fitted to the upper end portion of the column 7 that is the installation location, and the self-luminous delineator 1 in the fitted state. After adjusting the installation direction, a plurality of screws (for example, hexagon socket bolts) 8 screwed from the outer peripheral side of the lower cap 4 are pressed against or bitten into the outer peripheral portion of the column 7 to Are fixed together.

  In addition, the upper cap 3 and the lower cap 4 are fixed to the transparent pipe 2 in the same manner as the support 7. A plurality of screws (for example, hexagon socket bolts) screwed from the outer peripheral side of the upper cap 3 and the lower cap 4 are fixed. ) 8 is carried out by pressing or biting into the outer peripheral part of the transparent pipe 2.

  The light emitting unit 5 is installed in the upper half of the transparent pipe 2 and has a vertically long light emitting body case 5a and a plurality of light emitting bodies 5b arranged on the light emitting body case 5a at predetermined intervals in the vertical direction. And a light emission control board 5c for controlling the light emission operation of the light emitter 5b, and a pair of left and right reflectors 5d to be described later. The light emitting unit 5 has directivity, and when installed, it is necessary to adjust the direction of the light emitting unit 5 so that the light emitted from the light emitter 5b is visible to the vehicle driver. In the present embodiment, the light emitter 5b is configured by using a trumpet-shaped holder and the light emitting diode LED housed in the holder, but the configuration of the light emitter 5b is not limited to the above.

  The solar cell unit 6 is installed in the lower half of the transparent pipe 2 and generates power by receiving light such as sunlight and a vertically long solar cell unit case 6a formed by bending an aluminum plate material. A solar battery panel 6b and a storage battery 6c that stores the power generated by the solar battery panel 6b are provided, and power is supplied from the storage battery 6c to the light emitting unit 5. The solar cell panel 6b is disposed on a limited partial surface (for example, the front surface) of the solar cell unit case 6a. That is, the solar cell unit 6 incorporated in the self-luminous delineator 1 of the present invention has directivity, and the solar cell panel 6b faces a predetermined direction (usually facing south) during installation. It is necessary to adjust the orientation of the solar cell unit 6.

  In adjusting the orientation of the light emitting unit 5 and the solar cell unit 6 at the time of installation, the self-luminous delineator 1 of the present embodiment is arranged from the transparent pipe 2 to the upper cap 3 even after the lower cap 4 is fixed to the installation location. And without removing the lower cap 4, the direction of the light emitting unit 5 can be changed. More specifically, the solar cell portion 6 is internally provided below the hollow portion of the transparent pipe 2, and a lower end portion (an L-shaped portion formed at the lower end portion of the solar cell portion case 6 a) with respect to the lower cap 4. Are fixed (for example, screwed). Therefore, in a state where the lower cap 4 is rotatably fitted to the support column 7, the direction of the solar cell unit 6 (the direction of the self-luminous delineator 1) can be freely adjusted, and the lower cap 4 is mounted on the support column. By fixing to 7, the orientation of the solar cell unit 6 is determined.

  On the other hand, the light emitting part 5 is rotatably mounted on the upper side of the hollow part of the transparent pipe 2 and is engaged with the upper cap 3. Specifically, an engagement recess 3a is formed in the lower surface portion of the upper cap 3, and an upper end protruding piece of the light emitter case 5a is engaged with the engagement recess 3a in a non-rotatable manner. The upper cap 3 is rotatably fitted to the upper end portion of the transparent pipe 2. For example, a circular fitting recess 3 b is formed in the lower surface portion of the upper cap 3, and the fitting recess 3 b is fitted to the upper end portion of the transparent pipe 2. In this manner, the light emitting unit 5 is connected to the upper cap 3 so as to be rotatable together with the upper cap 3, and the upper cap 3 is rotatable with respect to the transparent pipe 2. Therefore, the upper cap 3 is rotated from the outside. For example, it is possible to freely change the direction of the light emitting unit 5 incorporated in the transparent pipe 2, and the direction of the light emitting unit 5 is determined by fixing the upper cap 3 to the transparent pipe 2.

  In addition, the member shown with the code | symbol 9 in a figure is a reflective sheet stuck on the outer peripheral surface of the transparent pipe 2, Comprising: By sticking this reflective sheet 9, the exposure unnecessary part in the transparent pipe 2 is shown. Not only can it be concealed and appearance deterioration can be avoided, but also the visibility at night can be improved by the reflective action of the reflective sheet 9.

  Next, the configuration of the light emitting unit 5 that is the gist of the present invention will be described in detail with reference to FIGS. 5 and 9. As described above, the light emitting unit 5 of the self-luminous delineator 1 according to the embodiment of the present invention includes a plurality of light emitters 5b and a pair of left and right reflectors 5d. The plurality of light emitters 5b are arranged in the vertical direction at the center in the transparent pipe 2, irradiate the emitted light toward the left and right outer sides, and the pair of left and right reflectors 5d are disposed in the transparent pipe 2 It is arrange | positioned at both right-and-left both ends, and the light which the light-emitting body 5b irradiated is reflected toward the front.

  In this way, two vertical rows of light are emitted from the left and right ends of the transparent pipe 2 toward the front, so that even in situations such as snowstorms, a single vertical row of snow is generated at the left and right central positions on the outer periphery of the pipe. However, both vertical two rows of light emission are not hidden by snowfall. As a result, the visibility required for the self-luminous delineator 1 can be secured even in a snowy state, and the driver's line of sight can be guided. Moreover, the two vertical rows of light emission are performed through the reflectors 5d disposed at the left and right ends of the transparent pipe 2, so that the light emitters 5b are disposed at the left and right ends of the transparent pipe 2. The light emission positions in two vertical rows can be made as close as possible to the left and right ends of the transparent pipe 2. As a result, it is possible to widen the left and right intervals of the light emission in the two vertical rows as much as possible, and to further reduce the possibility that both the light emission in the two vertical rows are hidden by snowfall.

  More specifically, the light emitter case 5a of the light emitting unit 5 includes a rear case 5e in a plan view and a front case 5f in a plan view that fits from the front to the rear case 5e. The left and right side surfaces of the front case 5f are respectively provided with a plurality of left illuminating light emitter support portions (round holes) 5g that support the left illuminating light emitter 5b and a right illuminating light emitter 5b. A plurality of right-side illuminating light-emitting body support portions (round holes) 5h to be supported are formed. Thereby, the some light-emitting body 5b is arrange | positioned along with the up-down direction in the center part in the transparent pipe 2, and can radiate | emit the emitted light toward the left-right outer side.

The left and right sides of the reflector 5i are inclined forward by 45 °, and the front surface thereof functions as the reflector 5d. Thereby, the pair of left and right reflectors 5d are disposed at the left and right ends of the transparent pipe 2, and can reflect the light emitted from the light emitter 5b forward. And in this way, since the reflector 5d is configured integrally with the light emitter case 5a that supports the plurality of light emitters 5b, not only the assembly of the self light emitting delineator 1 is improved, Adjustment of the irradiation direction can also be easily performed.

  As described above, the light emitter case 5a includes a plurality of left-side irradiation light-emitting body supporting portions 5g that support the left-side irradiation light-emitting body 5b and a plurality of right-side irradiation light-emitting bodies that support the right-side irradiation light-emitting body 5b. In providing the body support portion 5h, it is preferable that the left-side irradiation light-emitting body support portion 5g and the right-direction irradiation light-emitting body support portion 5h are formed by alternately shifting the positions in the vertical direction. This improves the arrangement efficiency of the light emitter 5b in the light emitter case 5a, so that not only the light emitter case 5a can be reduced in size but also a necessary space (such as a wiring space) in the light emitter case 5a. It can be secured easily.

  The reflector 5d can be configured by attaching a reflective film to a mirror-finished metal plate or a base material. And, when the reflector 5d is constituted by a mirror-finished metal plate, there is an advantage that the process of sticking a reflective film or the like is not required, and thus there is an advantage that the manufacturing cost can be reduced. When the reflector 5d is configured by sticking, the reflector 5d can be configured using a base material made of an arbitrary material.

  According to the present embodiment configured as described, a self-luminous delineator 1 which is provided in a plurality along the road and guides the line of sight to the driver of a passing vehicle, which is a vertically long cylindrical transparent pipe 2. And a light emitting unit 5 incorporated in the transparent pipe 2, and the light emitting unit 5 is arranged in the vertical direction at the center of the transparent pipe 2 and radiates emitted light toward the left and right outer sides. A plurality of light emitters 5b, and a pair of left and right reflectors 5d that are disposed at both left and right end portions in the transparent pipe 2 and reflect the light emitted from the light emitter 5b forward. Two vertical rows of light are emitted from both left and right ends of the inside of the pipe, even if a single row of vertical snowfall occurs at the left and right center of the outer periphery of the pipe under conditions such as snowstorms. Both are not hidden by snow. As a result, the visibility required for the self-luminous delineator 1 can be secured even in a snowy state, and the driver's line of sight can be guided.

  Moreover, the two vertical rows of light emission are performed through the reflectors 5d disposed at the left and right ends of the transparent pipe 2, so that the light emitters 5b are disposed at the left and right ends of the transparent pipe 2. The light emission positions in two vertical rows can be made as close as possible to the left and right ends of the transparent pipe 2. As a result, it is possible to widen the left and right intervals of the light emission in the two vertical rows as much as possible, and to further reduce the possibility that both the light emission in the two vertical rows are hidden by snowfall.

  Further, since the reflector 5d is configured integrally with the light emitter case 5a that supports the plurality of light emitters 5b, the reflector 5d and the light emitter case 5a can be integrated into the transparent pipe 2 as a result. In addition to improving the assemblability of the self-luminous delineator 1, the irradiation direction can be easily adjusted.

  The illuminator case 5a also includes a plurality of left illuminating light emitter support portions 5g that support the left illuminating light emitter 5b and a plurality of right illuminating light emitter supports that support the right illuminating light emitter 5b. 5h, and the left-side irradiation light-emitting body support part 5g and the right-side irradiation light-emitting body support part 5h are formed by alternately shifting the positions in the vertical direction, so that the light-emitting body in the light-emitting body case 5a The arrangement efficiency of 5b is improved, and not only can the light emitter case 5a be reduced in size, but also a necessary space (such as a wiring space) can be easily secured inside the light emitter case 5a.
