Description

本考案は、反射材を利用した視線誘導標や、自動車の運転者に注意を促す目的で設置される反射器に関する。The present invention relates to a gaze guide using a reflective material and a reflector installed for the purpose of calling a driver of an automobile to pay attention.

従来この種の技術としては、無着色で表面が透明な再帰反射器や、黄色の再帰反射器、必要な場所に黄色の反射テープを貼るなどの方法が知られている。Conventionally, as this kind of technique, there are known a non-colored retroreflector having a transparent surface, a yellow retroreflector, and attaching a yellow reflective tape to a necessary place.

無着色で表面が透明な再反射器は自動車ヘッドライトの光を効率よく反射するため、夜間など周りが暗い条件のとき視認性がよく、自動車の進行方向左の路肩を示す視線誘導標などに多数使用されている。The uncolored and transparent surface of the re-reflector reflects the light of the car headlights efficiently, so it is highly visible in dark surroundings such as at night, and is used as a line-of-sight guide sign indicating the road shoulder on the left side of the car's traveling direction. Many are used.

しかし、無着色で表面が透明な再帰反射器は、昼間は視認されにくい。However, a retroreflector that is uncolored and has a transparent surface is hardly visible during the day.

したがって、自動車の運転者に特に注意を促したい場所においては、昼間の視認性をよくするために、無着色で表面が透明な再反射器とは別に黄色の再帰反射器が設置されている。Therefore, in a place where the driver of the automobile is required to pay particular attention, a yellow retroreflector is provided separately from the non-colored and transparent surface of the retroreflector in order to improve daytime visibility.

従来の無着色で表面が透明な再帰反射器とは別に黄色の再帰反射器を設置する方法は、煩雑であるだけでなく、駐車場の出入り口等設置場所に制限のある場合には設置しにくい欠点があった。The method of installing a yellow retroreflector separately from the conventional non-colored retroreflector with a transparent surface is not only complicated, but also difficult to install when there are restrictions on the installation location such as the entrance of a parking lot. There were drawbacks.

本考案は、自動車の運転手から見て昼夜を問わず視認しやすく、設置するのが容易な再帰反射器を安価に提供しようとするものである。The present invention seeks to provide an inexpensive retroreflector that is easy for a driver of a motor vehicle to view day and night and is easy to install.

本考案における視線誘導標等の再帰反射器は、同一方向から見て無着色で表面が透明な反射効率の高い再帰反射板と、黄色又は橙色に近い黄色に見える再帰反射板が同時に視認できるように配置されている。The retroreflector such as a gaze guide mark in the present invention allows a retroreflector that is uncolored and has a transparent surface and a high reflection efficiency when viewed from the same direction, and a retroreflector that looks yellow or yellow close to orange at the same time. Are located in

無着色で表面が透明な再帰反射板と、黄色又は橙色に近い黄色に見える再帰反射板の、形・大きさ・配列は、使用場所の条件や使用目的によって変えることができる。The shape, size, and arrangement of the non-colored retroreflective plate having a transparent surface and the retroreflective plate that looks yellow or orange can be changed according to the conditions of the place of use and the purpose of use.

自動車の運転者に、道路の曲がり具合などを知らせ注意を促す目的で進行方向左に設置される視線誘導標や、夜や暗い条件の場所で危険な箇所を運転者に注意させる目的で設置される再帰反射器には、無着色で表面が透明な物が多く使用されてきた。無着色で表面が透明な再帰反射器は反射効率が良く、夜間自動車の運転手から視認されやすい。しかし、自動車が道路の路肩からはみ出したりはみ出しそうになったことがきっかけで起きる事故は、夜だけでなく明るい時間帯にも発生している。注意散漫な状態で自動車を運転し、立木や道路外の構造物など、固定された物に接触する事故も同様に、夜だけでなく明るい時間帯にも発生している。It is installed for the purpose of informing the driver of the vehicle that the road is turning, etc., and for giving attention to it. Many non-colored and transparent surfaces have been used as retroreflectors. An uncolored and transparent surface of a retroreflector has good reflection efficiency and is easily visible to a driver of a car at night. However, accidents triggered by the fact that a car is protruding or about to protrude from the shoulder of the road have occurred not only at night but also during bright hours. Driving a car in a distracted state and coming into contact with fixed objects, such as trees and structures off the road, occur not only at night but also during bright hours.

本考案による再帰反射器は、無着色で表面が透明な再帰反射板と黄色又は橙色に近い黄色に見える再帰反射板によって構成されるので、無着色で表面が透明な再帰反射板だけの物に比べて昼間の視認性がよく、明るい時間帯に自動車の運転者に注意を促すことができる。The retroreflector according to the present invention is composed of a non-colored retroreflective plate having a transparent surface and a retroreflective plate having a yellow or orange-appearing yellow color. In comparison, the visibility in the daytime is better, and the driver of the car can be alerted in a bright time zone.

無着色で表面が透明な再帰反射板と、黄色又は橙色に近い黄色に見える再帰反射板の大きさや配置は、容易に変えて製作できるので、設置場所の条件に対応しやすい。たとえば、自動車の運転者に昼間に特に注意を促したい場合は、黄色又は橙色に近い黄色に見える再帰反射板の割合を増やせばよい。Since the size and arrangement of the non-colored and transparent retroreflective plate and the retroreflective plate that looks yellow or orange can be easily changed, it is easy to respond to the conditions of the installation place. For example, if it is desired to alert the driver of the vehicle during the daytime, the ratio of the retroreflective plate that looks yellow or nearly yellow may be increased.

本考案による再帰反射器は、無着色で表面が透明な再帰反射板が自動車のヘッドライトの光を効率よく反射するだけでなく、黄色又は橙色に近い黄色に見える再帰反射板が、無着色の再帰反射板とは違う色でヘッドライトの光を反射するので、夜間自動車の運転者が視認しやすい。The retroreflector according to the present invention not only has an uncolored and transparent retroreflective plate efficiently reflect the light of the headlights of an automobile, but also has a non-colored retroreflector that looks yellow or orange. Since the light of the headlight is reflected in a color different from that of the retroreflective plate, the driver of the vehicle at night can easily see the light.

本考案による再帰反射器は昼も夜も視認しやすいので、従来のように無着色で表面が透明な再帰反射器とは別に黄色又は橙色に近い黄色に見える再帰反射器を取り付けるといった、複数個の再帰反射器を取り付ける方法に比べて、取り付ける場所や手間を減らすことができ、安価に設置することが可能となるばかりでなく、駐車場の出入り口等設置場所が狭いところでも設置しやすい。The retroreflector according to the present invention is easy to see both day and night. As compared with the method of attaching the retroreflector, the installation place and labor can be reduced, and not only can it be installed inexpensively, but also it is easy to install even where the installation place such as the entrance of a parking lot is narrow.

図１において、１は黄色又は橙色に近い黄色に見える再帰反射板である。再帰反射板は平面であり、自動車の運転者に正対するよう取り付けられる。設置場所の条件によっては、対向車の運転者から視認できるようこの再帰反射板の裏面に別の再帰反射板を取り付けたり、横から視認できるよう適当な角度で再帰反射板を取り付けるなど、複数枚取り付けても良い。In FIG. 1, reference numeral 1 denotes a retroreflective plate that looks yellow or orange. The retroreflector is flat and mounted to face the driver of the vehicle. Depending on the conditions of the installation location, multiple retroreflective plates may be attached to the back of this retroreflective plate so that the driver of the oncoming vehicle can see it, or a retroreflective plate may be attached at an appropriate angle so that it can be seen from the side May be attached.

図１の２は、無着色で表面が透明な再帰反射板である。上記同様に、設置場所の条件によっては、裏面や横にも複数枚取り付けても良い。Reference numeral 2 in FIG. 1 denotes a non-colored retroreflective plate having a transparent surface. Similarly to the above, depending on the conditions of the installation place, a plurality of sheets may be mounted on the back surface or side.

図１では地面にたてた形であるが、駐車場の壁面などに取り付けられるように板状に作っても良い。Although FIG. 1 shows a vertical shape, it may be formed in a plate shape so as to be attached to a wall surface of a parking lot or the like.

道路や駐車場の出入り口などに取り付け、自動車の運転者に危険な個所を知らせ注意を促すことができる。It can be attached to the entrance of roads and parking lots, etc., to alert the driver of a car to a dangerous place and to alert the driver.
