Description

【0001】
【発明の属する技術分野】
本発明は、色覚障害者が自動車を運転する際に使用するフィルタに関する。
【0002】
【従来の技術】
例えば特許第3246604号によって色覚障害者用の補正眼鏡が提案されている。この眼鏡を着用することにより、色覚障害者でも赤、緑、黄色の交通信号を判別することが出来る。
【0003】
【発明が解決しようとする課題】
しかしながら、上述の補正眼鏡は濃い着色剤を使用したり、また特殊な反射膜を用いるために、一見して特殊な眼鏡であるということが容易に判別でき、色覚障害者にとっては使用をためらうものである。
【0004】
【課題を解決するための手段】
本発明は上述の課題を解決するために、自動車の運転席上方に位置し、直射日光を遮るサンバイザに移動可能に取付けられ、色覚障害者の色覚異常を矯正する所定の色覚矯正スペクトルを有する色覚障害者用自動車運転用フィルタを備える。
【0005】
【発明の実施の形態】
以下、本発明の実施例を説明する。図1は自動車の車内を示す図である。運転手が着座する運転席の頭上には、日光が直接運転手の目に入るのを防止するために回動可能なサンバイザ1が設けられている。このサンバイザは自動車の進行方向と直交する方向に設けられた回動軸2に沿って回動可能とされ、図2はこのサンバイザ1を開いた状態を示す。
【0006】
通常、開いた状態のサンバイザ1の運転手側には鏡がついているが、本実施例においては色覚障害者用の色覚補正用フィルタ(以下、フィルタという)3が回動軸5によってサンバイザ1を回動させたときの運転手側に回動可能に取り付けられている。
【0007】
このフィルタ3はプラスチックを着色し、特定の波長の光線を吸収させて透過率を弱めるフィルタ効果によって色覚矯正スペクトル特性を有する。一方、ミラーコートと呼ばれる方法でフィルタ3を構成することも可能である。その場合、真空蒸着法やスパッタリングによって部分反射膜を形成し、この部分反射膜によって特定の波長の光を目に到達させないようにして色覚矯正スペクトル曲線を得る。
【0008】
図3はこのフィルタをサンバイザ3から開いた状態を示す。通常、図2に示すサンバイザ1を開いた状態において、サンバイザ1は運転手が正面を見たときの視線の斜め上方に位置し、上からの日光を遮る位置にある。従って、図2に示す位置にあるサンバイザ1から更にフィルタ3を開くと、フィルタ3は運転手の目線とほぼ同じ高さに位置する。従って、交通信号や道路標識等、正確な色認識を必要とする視覚情報は全てこのフィルタ3を通して見ることになる。
【0009】
一方、自動車の計器4はこのフィルタ3を介して見ることはできないが、何れも色情報を瞬時に判別しなければならないものではなく、フィルタ3を通して見る必要はない。
【0010】
なお、上述の実施例において、フィルタ3を別途個別に販売し、使用者がフィルタ3をサンバイザ1に自身で取付けることが出来るようにしてもよい。
【0011】
また、フィルタ3はサンバイザ1に回動可能に取付けるのではなく、スライド可能に取付けることにより、運転者の視線の高さに応じて調整可能に構成しても良い。
【0012】
【発明の効果】
以上のごとく、本発明によれば、適切な視認範囲内にフィルタが位置するため、特殊な眼鏡を使用することなく交通信号や道路標識を識別することができるものである。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a filter used when a color blind person drives a car.
[0002]
[Prior art]
For example, Japanese Patent No. 3246604 proposes correction glasses for a color vision impaired person. By wearing these glasses, even a person with color vision impairment can distinguish red, green, and yellow traffic signals.
[0003]
[Problems to be solved by the invention]
However, because the above-mentioned correction glasses use a dark colorant or use a special reflective film, it can be easily determined that they are special glasses at first glance, and those who are color blind people hesitate to use them. It is.
[0004]
[Means for Solving the Problems]
SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a color vision system having a predetermined color vision correction spectrum which is movably attached to a sun visor which is located above a driver's seat of a car and blocks direct sunlight and corrects color vision abnormality of a color blind person. A filter for driving a vehicle for the disabled is provided.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, examples of the present invention will be described. FIG. 1 is a diagram showing the inside of an automobile. A rotatable sun visor 1 is provided above the driver's seat where the driver sits to prevent sunlight from directly entering the driver's eyes. The sun visor is rotatable along a rotation shaft 2 provided in a direction perpendicular to the traveling direction of the vehicle. FIG. 2 shows a state where the sun visor 1 is opened.
[0006]
Normally, a mirror is attached to the driver side of the sun visor 1 in an open state, but in this embodiment, a color vision correction filter (hereinafter, referred to as a filter) 3 for a color vision impaired person is connected to the sun visor 1 by a rotation shaft 5. It is rotatably attached to the driver side when turned.
[0007]
The filter 3 has a color vision correcting spectrum characteristic by coloring a plastic and absorbing light having a specific wavelength to reduce the transmittance. On the other hand, the filter 3 can be configured by a method called a mirror coat. In this case, a partial reflection film is formed by a vacuum evaporation method or sputtering, and a color vision correction spectrum curve is obtained by using this partial reflection film to prevent light of a specific wavelength from reaching the eyes.
[0008]
FIG. 3 shows this filter opened from the sun visor 3. Normally, when the sun visor 1 shown in FIG. 2 is opened, the sun visor 1 is located diagonally above the line of sight when the driver looks at the front, and is in a position that blocks sunlight from above. Therefore, when the filter 3 is further opened from the sun visor 1 at the position shown in FIG. 2, the filter 3 is located at substantially the same height as the driver's eyes. Accordingly, all visual information that requires accurate color recognition, such as traffic signals and road signs, is viewed through the filter 3.
[0009]
On the other hand, the instrument 4 of the vehicle cannot be seen through the filter 3, but it is not necessary to determine the color information instantaneously, and it is not necessary to look through the filter 3.
[0010]
In the above-described embodiment, the filter 3 may be separately sold separately so that the user can attach the filter 3 to the sun visor 1 by himself.
[0011]
The filter 3 may not be rotatably attached to the sun visor 1 but may be slidably attached to the sun visor 1 so as to be adjustable according to the height of the driver's line of sight.
[0012]
【The invention's effect】
As described above, according to the present invention, since a filter is located within an appropriate viewing range, a traffic signal or a road sign can be identified without using special glasses.
[Brief description of the drawings]
FIG. 1 is a diagram showing the interior of an automobile in which a sun visor 1 is stored.
FIG. 2 is a diagram showing the interior of an automobile with a sun visor 1 opened.
FIG. 3 is a diagram showing the interior of an automobile in a state where a filter 3 is rotated from an opened sun visor 1;
