Description

  The present invention relates to a line-of-sight guidance sign column, and more particularly, to a phosphorescent line-of-sight guidance sign column that can improve the visibility due to light emission at night without using a battery.

  It is particularly important to ensure visibility at night, especially for gaze guidance sign columns that are installed on the road to mark sidewalks, outer lines, center lines, diversions, etc., and perform lane separation, gaze guidance, and the like.

  To ensure nighttime visibility, a retroreflective sheet with a light reflecting function is generally provided on the outer periphery of the pillar body. However, a roadway and sidewalk separation zone without street lights, a suburban lighting curve, etc. At night, a night-light-emitting gaze guidance sign column is used.

  Night-light-emitting line-of-sight sign pillars are equipped with LEDs as the light source, generate electricity with sunlight in the daytime, charge the built-in battery, and blink the LEDs at night to darken dark roads and curves without night street lights In the danger zone, etc., it alerts people and vehicles and is very useful from the viewpoint of preventing traffic accidents.

  Patent Document 1 discloses a line-of-sight guidance sign column in which an EL sheet is used as a light emission source, stored in an electric double layer capacitor by a solar cell in the daytime, and the EL sheet blinks at night.

  Further, Patent Document 2 includes a luminous material contained in the resin material of the cap portion and the pedestal portion, thereby improving visibility by a pedestrian at night, and in particular, avoiding the pedestrian from getting stuck. A sign post is disclosed.

  A line-of-sight guide sign column that blinks the light source at night is very effective especially in improving visibility at night. However, there was still room for improvement from the viewpoint of human and environmental friendliness and maintenance-free.

  In other words, since the light source is blinked, pedestrians and drivers complain that they are “irritated” and neighbors on the road are “bright and sleepless”.

  Also, lead is usually used for the built-in battery, but it is not environmentally friendly because it is an environmentally hazardous substance.

  In Patent Document 1, by using an EL sheet as a light emission source, there is an advantage that it is possible to slightly eliminate problems such as annoyance of pedestrians and the like and disturbance of sleep of neighboring residents that are seen when LEDs are blinked. Because of the built-in, there is still room for improvement in that a failure such as a disconnection is likely to occur due to a strong impact caused by a vehicle contact or the like, and the useful life of the solar cell is limited.

  On the other hand, Patent Document 2 is considered to be effective in that the light emission source does not blink and an electronic circuit becomes unnecessary. However, it is difficult to sufficiently secure the light emission luminance at night by simply including a phosphorescent material in the resin material, and it has been desired to further enhance the alerting effect particularly at night.

  Then, the subject of this invention makes it a subject to provide the luminous intensity | strength type | mold gaze guidance sign column which can raise the light emission brightness of the luminous material at night, and can further improve an alerting effect.

  Other problems of the present invention will become apparent from the following description.

The front view which shows an example of the gaze guidance sign pillar which concerns on this invention Explanatory drawing which shows the state which decomposed | disassembled the gaze guidance sign pillar shown in FIG. The front view which shows the other example of the gaze guidance sign pillar which concerns on this invention

  The line-of-sight guidance marker column according to the present invention is formed by covering the outer periphery of a white pipe body with a first outer pipe having transparency and containing a phosphorescent material.

  The pipe body can be made of a material that is generally used as a line-of-sight guide column, but is particularly flexible and preferably has returnability even when stepping on a vehicle or the like, such as elastically deformable polyurethane. Can be mentioned. The shape of the pipe body is generally a cylindrical shape, but may be a prismatic shape such as a triangular prism or a quadrangular prism. Moreover, the inside may be hollow or solid.

  The present invention is characterized in that the pipe body is white. The pipe body may be configured by adding a colorant or the like to make the material itself white. The pipe body is colored white or a white layer is laminated on the pipe body. You may comprise by doing.

  The pipe body is preferably white over its entire length, but at least the outer peripheral surface of the portion covered with the first outer pipe may be white.

  The first outer pipe is a cylindrical body whose inner diameter is 1 to 2 mm larger than the outer diameter of the pipe body, and by using a phosphorescent material, energy is stored by sunlight in the daytime and emits light at night, but has transparency. Therefore, by covering the outer periphery of the pipe body, the white color of the inner pipe body can be visually recognized from the outside due to its transparency.

  For this reason, the inner white pipe body can function as a white reflective layer. When the phosphorescent material emits light at night, the first outer layer at night is obtained by the light emitting function of the phosphorescent material itself and the white reflecting function of the pipe body. The pipe can be made to emit light with high light emission brightness, and the alerting effect by light emission can be improved. Also, during the daytime, the first outer pipe receives sunlight, and high visibility can be given to pedestrians and drivers by the reflection of the inner white pipe body.

  Since the first outer pipe emits light from the phosphorescent material, there is no worry about failure, and while it has high light emission brightness, it is a pedestrian's frustration such as when blinking a light source such as an LED, or a sleep of a nearby resident There are no problems such as obstruction.

  It is preferable for the luminous material to have a night emission color of green with an emission peak of 520 nm because nighttime visibility can be improved without causing discomfort to pedestrians and the like.

Such a phosphorescent material is preferably an aluminate-based phosphorescent material. The aluminate-based phosphorescent material is mainly composed of SrAl ₂ O ₄ : Eu, Dy (strontium aluminate: europium, desprosium), and is a non-toxic and environmentally friendly substance. In this invention, it is preferable that the aluminate type phosphorescent material with a particle size of 100-1000 micrometers is kneaded in the material of the 1st outer pipe with the kneading amount of 2000 g / m < ² > or more.

  In the present invention, a large amount of aluminate-based phosphorescent material is kneaded in a large amount into the first outer pipe as described above, so that the light can be emitted with high luminance at night, and the white pipe body inside A synergistic effect with the white reflection function of the can provide a higher alerting effect.

According to the inventors' experiment, when an aluminate-based phosphorescent material having a particle size of 100 to 1000 μm is kneaded into the material of the first outer pipe at a kneading amount of 2000 g / m ² or more, sunset 12 The emission luminance after the time was 20 mcd / m ² or more, and an extremely high emission luminance could be exhibited. Even if the same first outer pipe is caused to emit light, if no white pipe body is provided on the inside thereof, a 30% reduction in luminance is recognized, and the first outer pipe and the white pipe body on the inside in the present invention are recognized. The effect of exhibiting high light emission luminance was recognized by the synergistic effect.

  In addition, the first outer pipe containing the aluminate-based phosphorescent material is yellowish, so even during the daytime, the light transmitted through the first outer pipe and reflected by the inner white pipe body, In order to improve the visibility of the yellow first outer pipe, it is possible to improve the alerting effect in the daytime.

  Such a 1st outer pipe can be shape | molded in a pipe shape, for example by mixing a phosphorescent material in transparent non-yellowing urethane material, and casting.

  The first outer pipe is not particularly limited as long as it has transparency and can contain a phosphorescent material in its material, but is preferably made of a transparent non-yellowing urethane rubber material. Since the transparent non-yellowing urethane rubber does not discolor or hydrolyze due to use, when it contains a phosphorescent material, the light emission reduction rate is within 10% in a weathering test equivalent to 10 years. It is possible to maintain a high alerting function by high luminance light emission.

  The first outer pipe does not need to extend over the entire length of the line-of-sight guidance sign column, and may be at least part of the total length.

  In the present invention, in addition to the first outer pipe, a second outer pipe having a retroreflective sheet on the surface can be provided, and a visibility improving function by the retroreflective sheet can be added.

  That is, in the present invention, the second outer pipe having the retroreflective sheet on the outer peripheral surface can be coated on the outer periphery of the pipe body so that the first outer pipe and the second outer pipe are stacked in the height direction. .

  The retroreflective sheet provided on the outer peripheral surface of the second outer pipe can be a plurality of types, and when the white high-intensity reflective sheet and the orange high-intensity reflective sheet are respectively spirally wound, High visibility can be given by the reflection of spiral white and orange when irradiated with light and the contrast of white and orange appearing spirally in the daytime.

  A plurality of first outer pipes and second outer pipes may be stacked and covered in the height direction of the outer periphery of the pipe body.

  Hereinafter, specific examples of the present invention will be described with reference to the drawings.

  FIG. 1 is a front view showing an example of a line-of-sight guidance sign column according to the present invention, and FIG. 2 is an explanatory view showing an exploded state.

  In these drawings, 1 is a pipe body, 2 is a first outer pipe, 3 is a second outer pipe, 4 is a pedestal portion, 5 is a cap, and 6 is a fixing pin.

  The pipe body 1 is a hollow cylindrical resin pipe having a white surface over its entire length, and is erected on a pedestal portion 4 fixed to a road surface.

Here, the first outer pipe 2 is a transparent non-yellowing urethane rubber material in which an aluminate-based phosphorescent material having a particle size of 100 to 1000 μm is kneaded into the pipe material at a kneading amount of 2000 g / m ² or more. It has a length of about 1/3 of the total length of the pipe body 1 and has a cylindrical shape whose inner diameter is larger than the outer diameter of the pipe body 1.

  The second outer pipe 3 is a pipe made of synthetic resin such as cylindrical polypropylene or polyethylene having a length of about 2/3 of the total length of the pipe body 1, and has an inner diameter larger than the outer diameter of the pipe body 1. It is large and has the same outer diameter as the first outer pipe.

  On the outer peripheral surface of the second outer pipe 3, there are a first retroreflective sheet 3a made of a white high-intensity reflective sheet and a second retroreflective sheet 3b made of an orange high-intensity reflective sheet, each formed in a tape shape. These are wound spirally so as to alternate in the height direction at intervals.

  The first outer pipe 2 and the second outer pipe 3 are arranged such that the second outer pipe 3 and the first outer pipe 3 are arranged on the outer periphery from above the pipe body 1 so that the first outer pipe 2 is higher. The pipes 2 are inserted and covered in this order, and are stacked in two upper and lower stages.

  The upper portion of the first outer pipe 2 is covered with a cap 5, and the fixing pin 6 is fixed to the bush 1 b formed on the head portion 1 a of the pipe body 1 from above, thereby the first outer pipe 2. The pipe 2 and the second outer pipe 3 are fixed between the cap 5 and the pedestal 4 so as to be coaxial with the pipe body 1.

  Reference numeral 4 a denotes a retroreflective sheet made of a white high-intensity reflective sheet provided on the outer periphery of the pedestal portion 4.

  According to this gaze guidance sign column, the white pipe body 1 inside can be visually recognized through the transparent first outer pipe 2, so that at night, the light emitted from the phosphorescent material is converted into the white pipe body 1 inside. The first outer pipe 2 emits light with a high light emission brightness due to the light emission function of the phosphorescent material itself and the white reflection function of the pipe body 1, and more than the light emission brightness of a simple phosphorescent material alone. High light emission luminance can be obtained, and visibility can be improved as compared with the prior art, and the alerting effect can be further improved.

  Also, during the daytime, sunlight passes through the first outer pipe 2 and is reflected by the white pipe body 1 so that a large amount of aluminate-based phosphorescent material is kneaded in a large amount so that the yellowish color is obtained. The first outer pipe 2 which is tinged can be visually recognized as shining yellow, and a high alerting effect due to high visibility can be exhibited.

  Moreover, the first retroreflective sheet 3a and the second retroreflective sheet 3b that are spirally wound around the outer peripheral surface of the second outer pipe 3 are exposed to vehicle lights at night, and have a special spiral shape. In addition to giving high visibility as the reflective layer, high visibility can also be given due to the clear contrast of the spiral shape of white and orange in the daytime, and a further alerting effect can be exhibited.

  In addition, since the entire length of the pipe body 1 is white, the pipe color of the second outer pipe 3 is more effective. That is, when the pipe body 1 is dark, there is a problem that the color of the second outer pipe 3 is also dull. However, since the pipe body 1 is also white inside the second outer pipe 3, The pipe color of the outer pipe looks better and the product value can be increased.

  In this case, the color of the second outer pipe 3 can be used without restriction, and for example, a fluorescent color having high visibility and commercial value is used as the pipe color of the second outer pipe 3. You can also do that.

  When the second outer pipe 3 is provided in addition to the first outer pipe 2, a plurality of first outer pipes 2 and a plurality of second outer pipes 3 can be used as shown in FIG. Here, the case where two each is used is shown, and a pipe having a white surface over the entire length so that the first outer pipe 2 and the third outer pipe 3 are alternately arranged in order from the top. The outer periphery of the main body 1 is covered and stacked, and is fixed to the pipe main body 1 by a cap 5 and a fixing pin 6.

  In this case, the light emission by the first outer pipe 2 and the reflection of the second outer pipe 3 are alternately formed in the height direction, so that the visibility can be further improved and a further alerting effect can be exhibited.
