  Therefore, in the conventional curb blocks installed on the road so as to separate the roadway from the sidewalk, the boundary of the structure where the light emitting diode is housed in the block body and light is emitted to the sidewalk side from the transparent cover provided on a part of the side wall A block light-emitting device has been proposed in Patent Document 1 and the like.

  However, although this boundary block light emitting device can illuminate the sidewalk side by turning on the light emitting diode at night, it is difficult for pedestrians to recognize how high the curb block is installed. There was a problem. In particular, when a pedestrian crossing is connected to a roadway with a sidewalk where a curb block is installed, or when a pedestrian travels from the roadway side to the sidewalk side or from the sidewalk side to the roadway side, Since the light-emitting diode provided on the side only illuminates the sidewalk side, it is difficult for pedestrians to recognize the height of the curb block, and it is easy to trip over the curb block when straddling the edge of the curb block. There was a problem.

  Therefore, the inventors of the present application have proposed a curb block light emitting device that emits light well in a state that is easily recognized by a pedestrian in Patent Document 2 described above. Although this conventional curb block light emitting device can radiate colored light from the colored light radiating part well, alert the pedestrian, and illuminate the sidewalk well, leading the pedestrian to the sidewalk, There is a problem that the structure becomes complicated and the manufacturing cost increases.

  The present invention has been made in view of the above points, and at night, a pedestrian can be safely guided from a sidewalk to a pedestrian crossing or from a pedestrian crossing to a roadway, and the structure is simple and inexpensive to manufacture. The object is to provide a possible curb block device.

In order to achieve the above object, the curb block device of the present invention has a light emitter disposed in a block body of a curb block laid along the boundary between a roadway and a sidewalk, and emits light by light emission of the light emitter. In the curb block device, the block main body is formed into a predetermined shape using recycled plastic as a material, and a light emitting chamber and a power storage chamber are formed in the block main body by opening an upper portion, and a light emitter is arranged in the light emitting chamber. The light emitter is provided with a reflecting plate attached to the upper surface of the mounting substrate disposed in the light emitting chamber, and a plurality of LEDs that emit colored light are attached to both sides of the reflecting plate on the mounting substrate. A control board for controlling the light emission of the LED is provided on the lower surface of the mounting board, and a surface-emitting transparent plate is fixed to cover the upper surface of the light-emitting chamber. The entire A light diffusing surface or a light diffusing layer is formed, a non-slip uneven portion is formed on the upper surface of the surface light emitting transparent plate, a power storage unit is disposed in the power storage chamber, and covers the upper surface of the power storage chamber A solar cell panel is attached, and the colored light of the LED is emitted to the light diffusing surface or the light diffusing layer of the surface-emitting transparent plate, and the entire upper surface of the surface-emitting transparent plate is colored and emits light. To do.

Here, in the curb block device, as described in claim 2, an anchor pin can be provided in the lower portion of the block main body so as to protrude laterally.

  The curb block device having the above configuration can be manufactured at low cost and in consideration of the global environment because the block body is formed of recycled plastic. Further, since the structure is a simple structure in which a light emitter is attached to a light emitting chamber formed in the block main body and a transparent plate is attached so as to cover the upper surface, the apparatus can be manufactured at low cost.

  The curb block of this curb block device is formed, for example, with a block having a horizontal upper surface and a curb block having an inclined upper surface with gradually different heights, and these are laid side by side at the boundary between the sidewalk and the roadway. . When a pedestrian crossing is connected to the sidewalk, the curb blocks are laid with an inclined upper surface so that the height of the curb block gradually decreases as the pedestrian crossing is approached.

  At night, the light emitters in each curb block device are turned on (including blinking) by the electric power supplied from the power storage unit, and the light is emitted upward from the surface-emitting transparent plate on the upper surface of the light emitter. Since the light diffusing surface or the light diffusing layer is formed on substantially the entire inner surface or outer surface or inside of the surface emitting transparent plate, the entire upper surface of the light emitter emits light. Therefore, the pedestrian can easily recognize the curb block that emits the surface light easily from a distance without feeling dazzling. For this reason, even if the pedestrian is an elderly person with a weak eye or a handicapped person, the top surface of the curb block that emits light is easily recognized, and attention is drawn to the pedestrian. It can be safely guided.

Also, a colored filter that reduces the light transmittance , such as using a LED that emits colored light as a light emitter, and emitting the colored light of the LED to the light diffusing surface or light diffusing layer of the surface emitting transparent plate to cause surface emission. the without, with and sufficient amount of light colored light such as arousal easily yellow attention across the transparent plate can be surface-emitting. Furthermore, by projecting the anchor pin at the lower part of the block body, when the curb block is laid, the anchor pin can be embedded inside the asphalt road surface and the curb block can be firmly fixed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a perspective view of a typical curb block 1 of a curb block device. The block main body 2 of the curb block 1 is molded into a trapezoidal block shape with the upper surface inclined by using recycled plastic as a synthetic resin material. As the recycled plastic, a material recycled plastic such as polyethylene and polystyrene can be used, and the molded block body 2 is lighter than concrete and has sufficient strength.

  As shown in FIG. 5, a light emitting chamber 3 and a power storage chamber 4 are formed in the block body 2. The light emitting chamber 3 and the power storage chamber 4 are formed with an upper surface opened, and a recess is formed at the bottom for removing the meat. In addition, two anchor pins 10 are fixed to the front and rear lower portions of the block main body 2 so as to protrude in the lateral direction, and are firmly fixed by an anchor action when embedded.

  A light emitter 5 is disposed in the light emitting chamber 3. As shown in FIG. 6, the light emitter 5 is configured by attaching a plurality of LEDs (light emitting diodes) 51 on both sides of a mounting substrate 53. A reflection plate 52 is attached to the upper surface of the attachment substrate 53, and a control substrate 54 on which a control circuit is mounted is attached to the lower surface. As the LED 51, an LED that emits colored light (for example, yellow light) is used.

  Although the illustration of the configuration of the control circuit mounted on the control board 54 is omitted, a charging circuit for charging the power storage unit 7 with power generated in the daytime by a solar cell panel 8 described later, and at night when power generation is stopped The control circuit is configured to include a lighting control circuit that switches to supply power to the LED 51 and drives it to light, and a day / night discrimination circuit that discriminates day / night based on the voltage of the solar battery panel 8. When the circuit determines night, the LED lighting circuit is turned on to operate the LED 51.

  The opened upper surface of the light emitting chamber 3 is closed so as to be covered by the surface light emitting transparent plate 6. The surface-emitting transparent plate 6 is transparent and is formed into a plate shape with a polycarbonate resin, and the inner surface of the surface-emitting transparent plate 6 has a light diffusing surface 61 for diffusing light by applying a finish or the like. Is formed.

  Here, the light diffusing surface 61 is formed on the inner side surface of the surface light emitting transparent plate 6. However, in the case where the entire surface is illuminated by irradiating light from below, a light diffusing layer is formed inside the transparent plate ( The transparent plate may be formed of a transparent synthetic resin material containing a light diffusing agent), or a light diffusing surface may be formed on the outer surface of the transparent plate to cause surface emission.

  Thereby, light is radiated | emitted upwards directly from some LED51 of the light emitter 5 attached in the light emission chamber 3, or through the reflecting plate 52, and light is a light-diffusion surface inside the surface emitting transparent plate 6 When it hits 61, the light enters the surface light emitting transparent plate 6 while diffusing to the whole. This diffused light is radiated outward (upward) from the surface light emitting transparent plate 6, and the surface light emitting transparent plate 6 performs surface light emission so that the whole surface light emitting transparent plate 6 emits yellow light, for example. Further, a non-slip uneven portion 62 is formed on the upper surface of the surface light emitting transparent plate 6 so that even if a pedestrian accidentally puts his or her foot on it, it is difficult to slip.

  On the other hand, a power storage unit 7 is accommodated in the power storage chamber 4 of the block body 2. For example, an electric double layer capacitor is used for the power storage unit 7, and the electric power generated by the solar cell panel 8 is stored in the electric double layer capacitor of the power storage unit 7. An electric double layer capacitor uses activated carbon as an electrode, dilute sulfuric acid as an electrolyte, and a spacer interposed between the electrodes of both electrodes. Its power density is one order of magnitude larger than that of a normal secondary battery, and it is rapidly A rapid discharge of a large current is possible with charging. Moreover, the number of times of charging / discharging can be almost unlimited, and maintenance is not required. Thus, the power storage unit used in the curb block has optimum performance.

  A solar cell panel 8 is attached to the upper opening of the electricity storage chamber 4 so as to cover and close the opening, and a protective transparent plate 9 made of a transparent polycarbonate resin is further provided on the upper surface of the solar cell panel 8. It is fixed so as to cover the panel 8. The solar battery panel 8 receives sunlight in the daytime to generate an electromotive force, supplies a charging current to the power storage unit 7 through the charging circuit, and stores the power in the power storage unit 7.

  The curb block 1 having the above structure is manufactured as shown in FIG. 7 with a plurality of curb blocks 1a to 1c having different heights and inclination angles on the upper surface, and these curb blocks 1a to 1c are as shown in FIG. For example, it is laid side by side at the boundary between the sidewalk and the roadway. It is also possible to produce concrete curb blocks with the upper surface horizontal and to install them side by side so as to connect the curb blocks made of concrete following the sloping curb block 1a.

  The curb blocks 1a to 1c are installed by burying the bottom of the block main body 2 in a paved portion such as asphalt. At this time, the anchor pin 10 protruding horizontally from the block main body 2 is also embedded together. The curb block is installed with sufficient fixing strength.

  In the daytime, the solar battery panels 8 of the curb blocks 1a to 1c receive sunlight to generate electromotive force, and charge the power storage unit 7 through the charging circuit. At night, when the day / night discrimination circuit outputs a night judgment signal, the lighting circuit drives the LED 51 of the light emitter 5 to light by the operation of the control circuit, and the LED 51 is lit.

  The yellow light emitted from the LED 51 of the light emitter 5 in the curb blocks 1a to 1c is reflected directly or by the reflecting plate 52 or the like, and is reflected on the light diffusion surface 61 on the inner side surface of the surface emitting transparent plate 6 on the upper surface. The diffused light diffused by the light diffusing surface 61 passes through the surface emitting transparent plate 6 and is emitted upward. For this reason, the surface emitting transparent plate 6 shines so that substantially the entire surface emits light, and yellow light is emitted to the entire upper surface of the surface emitting transparent plate 6.

  In general, when a point light source or the like is directly viewed in the dark state at night, the surroundings cannot be seen well, but the surface light-emitting transparency 61 is transparent by the light diffusion surface 61 on the inner surface of the surface light-emitting transparent plate 6. In the curb block where the board 6 emits light, even if the pedestrian is an elderly person with a weak eye or a handicapped person, he / she sees it without feeling glare and recognizes that there is a curb block. The state can be easily visually confirmed. Therefore, a pedestrian such as an elderly person recognizes that the curb blocks 1a to 1c are laid at the position, and is alerted when straddling the curb block. For this reason, even if a pedestrian is an elderly person with a weak eye or a handicapped person, the boundary part of a sidewalk and a roadway can be easily recognized at night, and the place can be walked safely.

  When the pedestrian crosses the curb blocks 1a to 1c, for example, from the side of the pedestrian to the side of the pedestrian or from the side of the pedestrian to the side of the road, the pedestrian is provided on the upper surface of the curb blocks 1a to 1c. Since yellow light is emitted in a planar shape from the surface-emitting transparent plate 6, the height of the curb block is easily recognized by the pedestrian, and attention is drawn to the pedestrian so that the pedestrian has weak eyes and obstacles. Even a person can safely guide the curb blocks 1a to 1c without tripping.

  In addition, the curb block device of the present invention is not limited to the above embodiment, and can also be implemented in the following modes.

  1) In the above embodiment, the yellow light LED is continuously lit, but a blinking circuit can be provided to cause the LED to blink, and an LED that emits light in chromatic colors such as red, blue, and orange should be used. You can also. Moreover, when blinking LED, it can also be blinked synchronously with LED of the other curb blocks 1a-1c, or relay blink operation | movement with these curb blocks 1a-1c can also be carried out.

  2) In the above embodiment, the LED was turned on based on the night discrimination signal from the day / night discrimination circuit, but the human body detector was installed in or near the curb block 1 and the night discrimination signal was output at night. In the state, when the human body detector detects the approach of a person, the LED can be turned on or blinked.

  3) Furthermore, when the human body detector detects the approach of a person, a sound generator that generates a sound to call attention along with the lighting / flashing of the LED can be provided in or near the curb block.

  As described above, according to the curb block device of the present invention, since the block body is formed of recycled plastic, it can be manufactured at low cost and in consideration of the global environment. Further, since the structure is a simple structure in which a light emitter is attached to a light emitting chamber formed in the block main body and a transparent plate is attached so as to cover the upper surface, the apparatus can be manufactured at low cost. Further, a surface emitting transparent plate is provided on the upper surface of the light emitter, and the substantially transparent plate as a whole is surface-emitted by a light diffusing surface or light diffusing layer provided on the inner side surface or the outer side surface of the surface emitting transparent plate or substantially the whole inside. Therefore, even if the pedestrian is an elderly person with a weak eye or a handicapped person, the upper surface of the curb block that emits light can be seen without feeling dazzling, and the surrounding conditions can be easily recognized. And can safely guide the pedestrian without tripping over the curb block.
