Abstract

<P>PROBLEM TO BE SOLVED: To provide a self-luminous road tack, having favorable visibility to a road user. <P>SOLUTION: Light emitted from a self-luminous body 71 is made to enter from the base 62 of a cylindrical body 6, whereby the incident light is repeatedly reflected complicatedly on the inner wall surface 64 and the outer wall surface 63 of the cylindrical body 6, so that the light emitted from the inner wall surface 64 and the outer wall surface 63 and the light emitted from an upper inclined surface 61 cause the cylindrical body to shine on the whole in spite of a partial difference in luminance to perform planar light emission. The light is emitted in a planar manner from a top cover 2. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a self-luminous roadway installed at various places around a road, such as road outer lines, center lines, intersection centers, median strips, curbs, and sidewalks.

  Various inventions have been made on self-luminous road fences that are installed on the road and display the outer line at night and guide the line of sight. For example, Patent Document 1 includes a solar cell, a storage battery, and a light source inside. In a self-light-emitting road fence made by a road light emitting sign apparatus in which at least the front cover part of the case has translucency, the light source is arranged such that its optical axis is inclined with respect to the surface of the front cover part, Furthermore, by providing a flat portion on the back surface of the front cover portion that faces the light source and is substantially orthogonal to the optical axis of the light source, the surface of the self-luminous road fence is substantially coincident with the road surface. Even when installed on the road, the self-luminous road fence is designed to emit light from the light source at a low angle with respect to the road surface so that it can be easily recognized by road users such as vehicle drivers. Is disclosed.

Japanese Patent Laid-Open No. 7-259036

  However, in the self-luminous road fence described in Patent Document 1, since the road surface and the surface of the self-luminous road fence are almost flush with each other, light emitted from a point light source such as a light-emitting diode is reflected in the front cover. Since the amount of light emitted to the outside is small, a sufficient amount of light cannot be obtained, and the effect of guiding the line of sight to the vehicle driver cannot be exhibited sufficiently. Also, for pedestrians and bicycles with different viewpoints from the vehicle driver, the light emission from the light source is emitted at a low angle, so the light axis is misaligned and the light emission is dark and the visibility is low. There was a problem I said.

  The present invention has been made to solve the above-described problems, and is intended to provide a self-luminous roadway having good visibility for road users.

  In order to achieve the above object, the present invention is configured as follows. That is, the self-luminous road fence according to the present invention includes a main body case having a self-luminous body, an outer peripheral wall formed around the bottom and an open top, and a translucent upper surface that closes the opening of the main body case. In a self-luminous roadway which is composed of a cover and a hollow portion formed by the main body case and the upper surface cover, and is installed so that the upper surface of the upper surface cover is substantially flush with the road surface, the hollow portion is made transparent. A cylindrical body having an upper inclined surface that is cut out in an inclined manner toward the outside, and the light emitted from the self-luminous body is cylindrically formed from the bottom surface of the cylindrical body. The light is incident on the body, and the cylindrical body is caused to emit light in a planar shape by the light and is emitted in a planar shape from the upper surface cover.

  In the present invention, the self-light-emitting body may be a surface light-emitting body such as electroluminescence, but may be a point light-emitting body such as a light-emitting diode, and even a point light-emitting body is emitted from the self-light-emitting body according to the present invention. By making light incident from the bottom surface of the cylindrical body, the incident light repeats complex reflections on the inner wall surface and the outer wall surface of the cylindrical body, and the light emitted from the inner wall surface and the outer wall surface and the upper inclined surface Although there is a partial difference in illuminance due to the light emitted from, the entire cylindrical body shines and emits light in a planar shape. These lights are emitted in a planar shape from the upper surface cover. Furthermore, by providing an upper inclined surface that is cut out in an inclined manner outwardly at the upper portion of the cylindrical body, light incident from the self-luminous body can be reflected by the upper inclined surface to the inside of the cylindrical body Therefore, this light can also be used effectively as light to be emitted in a planar shape, and the visibility of the self-luminous roadway can be further improved.

  Further, if the cylindrical body is formed of a light diffusing resin, the light emitted from the self-luminous body can be diffused in the cylindrical body, so that the cylindrical body emits light almost uniformly in a planar shape. This is preferable because the visibility of the self-luminous roadway is further improved.

  Further, if the bottom surface of the cylindrical body is formed in a concave lens shape, the light from the self-luminous body can be diffused, and similarly, the cylindrical body can emit light more planarly, and visibility A good self-luminous road fence can be provided.

  Further, if a plurality of V grooves or prism cuts are formed in the side surface of the cylindrical body in the horizontal direction, light incident on the cylindrical body can be reflected toward the inside of the cylindrical body. The light emitted from the body can be efficiently used for the surface emission of the cylindrical body, and the visibility of the self-luminous roadway can be further improved.

BEST MODE FOR CARRYING OUT THE INVENTION The best embodiment according to the present invention will be specifically described below with reference to the drawings.
1A and 1B show an embodiment of a self-luminous road fence according to the present invention. FIG. 1A is a plan view and FIG.
Reference numeral 1 denotes a body case in which an outer peripheral wall 11 is formed around a bottom portion and an upper portion is opened. A hook-shaped attachment portion 12 projects from the upper portion of the outer peripheral wall 11, and the attachment portion 12 includes Six bolt holes are formed at equal intervals. The upper end of the outer peripheral wall 11 is provided above the upper end of the attachment portion 12. Reference numeral 2 denotes an upper surface cover 2 provided on the upper portion of the main body case 1, and a peripheral edge portion 21 of the upper surface cover 2 is placed on the upper end of the outer peripheral wall 11 so as to close the opening of the main body case 1. Further, the lower surface 23 of the upper surface cover 2 is provided with an inclined surface 24 inclined outward and downward over the entire circumference. Reference numeral 3 denotes an upper surface cover fixing member, which is composed of a ring body having a reverse L-shaped cross section including an upper pressing portion 31 and a peripheral mounting portion 32, and is externally fitted to the upper surface cover 2. A bolt hole corresponding to the bolt hole drilled in the attachment portion 12 is carved at the lower end of the attachment portion 32, and the main body case 1 is inserted and screwed into both bolt holes from below the main body case 1 to be screwed. The upper surface cover fixing member 3 is attached to the upper surface cover 2, and the peripheral portion 21 of the upper surface cover 2 is sandwiched and fixed between the pressing portion 31 of the upper surface cover fixing member 3 and the upper end of the outer peripheral wall 11 of the main body case 1. At this time, the outer peripheral side surface of the upper end of the outer peripheral wall 11 of the main body case 1 and the side surface 25 of the top cover 2 are brought into contact with the inner peripheral side surface of the top cover fixing member 3.

  The upper surface 22 of the upper surface cover 2 and the upper surface of the pressing portion 31 of the upper surface cover fixing member 3 are in a state where the peripheral edge portion 21 of the upper surface cover 2 is fixed between the upper surface cover fixing member 3 and the main body case 1. When being embedded in the road surface, the upper surface of the pressing portion 31 is embedded substantially flush with the road surface.

  Further, a groove is formed over the entire periphery of the upper end of the outer peripheral wall 11 of the main body case 1 and the peripheral edge 21 of the upper surface cover 2, and the first packing material 5A and the second packing material 5B are inserted into the groove. Yes.

  Reference numeral 6 denotes a light-transmitting cylindrical body, which is disposed above a self-luminous body 71 described later, and light from the self-luminous body 71 is incident from the bottom surface 62 of the cylindrical body 6 as shown in FIG. An upper inclined surface 61 is formed on the upper portion thereof so as to be inclined outwardly, and the upper inclined surface 61 is in contact with the upper inclined surface 24 provided on the lower surface 23 of the upper surface cover 2. Has been made. Further, a plurality of V grooves of approximately 90 ° are engraved on the outer wall surface 63 over the entire circumference. If the upper inclined surface 61 is formed on the cylindrical body 6, the light emitted from the self-luminous body 71 can be reflected to the inner wall surface 64 side of the cylindrical body 6. It is preferable that the light can be used effectively and the visibility of the self-luminous roadway 10 can be further improved. In addition, when the inclination angle of the upper inclined surface 61 was 40 to 50 °, the visibility of the self-luminous roadway 10 was good. Further, by engraving a plurality of substantially 90 ° V-grooves on the outer wall surface 63 over the entire circumference, the light of the self-luminous body 71 incident from the bottom surface 62 can be refracted toward the inner wall surface 64 side. The visibility of the self-luminous roadway 10 can be improved. In addition, if the bottom surface 62 is formed in a concave lens shape, the light of the self-luminous body 71 can be diffused inside the cylindrical body 6 and the visibility of the self-luminous roadway 10 can be improved. Furthermore, if a reflection sheet is provided on the entire circumference of the outer wall surface 63 of the cylindrical body 6, light from the self-luminous body 71 can be prevented from leaking from the outer wall surface 63 of the cylindrical body 6, and light from the self-luminous body 71 can be prevented. Therefore, the visibility of the self-luminous road fence 10 can be further improved.

  Reference numeral 7 denotes a light emitting unit, which is composed of a self-luminous body 71, a circuit board 72, a connection (not shown) connecting them, and the like, together with a power storage device 8 as a power source, a solar cell 9 that generates power by sunlight The main body case 1 and the upper surface cover 2 are accommodated in a hollow portion 101.

  In this embodiment, the self-luminous body 71 uses six chip-type light emitting diodes. Thereby, the visibility of the self-luminous roadway can be ensured from any direction of 360 °, but the number is not limited and may be changed depending on the installation location and the installation target. The light emitting method may be used as appropriate, such as blinking and lighting, but it emits light at high speed at a cycle that can be seen as always emitting light by suppressing the power consumption and using the afterimage effect, for example, 40 times / second. It is good to let them.

  The self-luminous body 71 is not particularly limited as long as it emits light. In addition to a bullet-type light emitting diode, a halogen lamp, a metal halide lamp, a cathode tube, electroluminescence, a xenon lamp, or the like is appropriately used. . In addition, as a power source, when a battery such as a lithium battery is used for the power storage device 8, it is not necessary to use another power source device, but when a charging device such as a lead storage battery or an electric double layer capacitor is used for the power storage device 8, As a power source for charging this, a commercial power source, a normally used solar cell 9 or the like is used. When using the solar cell 9, the solar cell 9 is disposed below the translucent upper surface cover 2, and the power of the solar cell 9 generated by the sunlight transmitted through the upper surface cover 2 is charged in the power storage device 8. However, the solar cell 9 may be installed separately from the main roadway.

  The body case 1 may be a die-cast product or cast product of a metal material such as an aluminum alloy or zinc, but the upper part of the body case 1 is processed flat for a die-cast product or cast product of a metal material. Since the cost for post-processing is high, it is preferable to form a synthetic resin material such as a polycarbonate resin, a modified polyphenylene ether resin, a polyacetal resin, a polybutylene terephthalate resin, or a nylon resin by injection molding. By such formation, the cost for flat processing can be eliminated. Furthermore, strength may be improved by mixing glass fiber with the synthetic resin material. Among them, it is preferable to mix and mold glass fibers with a modified polyphenylene ether resin that has lower water absorption than polycarbonate resin and has substantially the same linear expansion coefficient. By using such a material, not only can the water absorption of the main body case itself be reduced, but when the upper surface cover 2 is formed of polycarbonate resin, the linear expansion coefficients of the main body case 1 and the upper surface cover 2 become substantially equal. When the main body case 1 and the upper surface cover 2 expand and contract due to the change of the length, both of them expand and contract by almost the same length, so that the gap between the main body case 1 and the upper surface cover 2 can be almost eliminated and water intrusion is prevented. The airtightness of the hollow portion 101 can be maintained.

  The top cover 2 is not particularly limited as long as it has translucency. However, since it is installed in a place where it can be ridden on a vehicle or the like, a polycarbonate resin resistant to impact is preferably used. Etc. can also be used.

  Since the upper surface cover fixing member 3 is configured such that the peripheral edge portion 21 of the upper surface cover 2 is clamped between the upper surface cover fixing member 3 and the main body case 1 by bolts 4 screwed into bolt holes provided at equal intervals. It is preferable to use a metal material such as an aluminum alloy or zinc by die casting or casting.

  The cylindrical body 6 may be formed using a synthetic resin material, glass, or the like as long as it is transparent so as to transmit light emitted from the self-luminous body 71, and the material is not particularly limited. An acrylic resin that has high light transmittance and is easy to be molded is most preferably used.

  When providing a reflection sheet used for the entire outer side surface 63 of the cylindrical body 6, the reflection sheet is a reflection sheet in which glass beads or prism reflectors are arranged on the surface, a synthetic resin sheet in which glass beads are embedded, and the like. It can be used as appropriate.

  The first packing material 5 </ b> A and the second packing material 5 </ b> B are formed by screwing bolts 4, so that the upper end of the outer peripheral wall 11 of the main body case 1, the lower end of the peripheral edge 21 of the top cover 2, and the lower end of the pressing member 31 of the fixing member 3. It is possible to reliably prevent intrusion of water such as rain water and dust into the hollow portion 101. In addition, since it is not necessary to perform sealing processing using a sealing agent or the like to prevent intrusion of water, dust, or the like, time and cost for the sealing processing can be eliminated.

  Further, since the upper end of the outer peripheral wall 11 is provided above the upper end of the attachment portion 12, even if water enters from above the buried road fence 10, it is at a position lower than the upper end of the outer peripheral wall 11. Since it flows toward the upper end of the attachment part 12, waterproofing to the hollow part 101 can be made relatively easily.

  The first packing material 5 </ b> A and the second packing material 5 </ b> B are not particularly limited as long as they have high resistance to water, but an elastic body that generates deformation and repulsive force by tightening the bolt 4 is used. If used, the fine gaps between the main body case 1, the upper surface cover 2, and the fixing member 3 can be closed, so that it is possible to protect the light emitting unit 7, the power storage device 8 and the like over a long period of time. . Thus, for example, natural rubber, butadiene styrene rubber, neoprene, butadiene acrylonitrile rubber, chloroprene polymer, butyl rubber, ethylene propylene terpolymer, urethane resin, polyisobutylene resin, polyethylene resin, ethylene vinyl acetate copolymer, silicone resin, soft and Elastic materials made of various synthetic rubbers such as hard vinyl chloride resins and elastomers, synthetic resins, and the like, or foamed materials thereof may be used.

It is the top view and sectional drawing which show the 1st Example of the self-light-emitting road fence concerning this invention. It is a notch perspective view of a cylindrical body.
