Description

本考案はピンホール眼鏡に関する。  The present invention relates to pinhole glasses.

従来、ピンホール効果により、一時的な視力の矯正を行うことのできるピンホール眼鏡が知られている。
また、ピンホール眼鏡に定規の機能を付けたものが提案されていた(特許文献1参照)。
2. Description of the Related Art Conventionally, pinhole glasses that can temporarily correct visual acuity by the pinhole effect are known.
Further, a pinhole spectacle having a ruler function has been proposed (see Patent Document 1).

特開2011−118321JP2011-118321A

これには次のような課題があった。
従来ピンホール眼鏡は眼鏡としての用途が主であり、通常の眼鏡と同様、眼鏡型の形状となっている。例に挙げた特許文献1においても「眼鏡の形」であることが明記されている。
This has the following problems.
Conventional pinhole eyeglasses are mainly used as eyeglasses, and have the shape of eyeglasses like ordinary eyeglasses. In Patent Document 1 cited as an example, it is specified that the shape is “glasses shape”.

しかし、眼鏡としての用途が主であると、常に意識して携帯していなくてはならず、例えば、黒板に書かれた文字の一部が小さく書かれていて見えないといった予期できぬ突発的な状況において、素早くピンホールメガネ使用することは困難である。  However, if it is mainly used as a spectacle, you must always carry it with consciousness. For example, some unexpected letters such as small letters written on the blackboard cannot be seen. In such a situation, it is difficult to use pinhole glasses quickly.

また、通常のレンズを用いた眼鏡を使用している者の場合、その上にピンホール眼鏡を重ねてかけて使用することは、眼鏡のフレーム同士が重なり合ってしまい困難である。  In addition, in the case of a person using spectacles using a normal lens, it is difficult to use pinhole spectacles on top of them because the frames of the spectacles overlap each other.

さらに、眼鏡型の場合、顔のサイズによってはきつかったり、ゆるかったりして使用できないといった課題があった。  Furthermore, in the case of the glasses type, there is a problem that it cannot be used because it is too tight or loose depending on the size of the face.

また、ピンホール効果は部屋の明暗によって見え方が左右され、一番よく見える最適径があるわけではない。基本的には孔の径が小さいと見えやすい傾向があるものの、部屋が暗い場合は見え方が暗くなりすぎてしまい、孔の径が大きいほうが見やすい場合もある。
本考案は以上のような課題を解決するために、なされたものである。
In addition, the pinhole effect is affected by the light and darkness of the room, and it does not have the optimum diameter that can be seen best. Basically, it tends to be visible when the diameter of the hole is small, but when the room is dark, the appearance becomes too dark, and there are cases where the larger diameter is easier to see.
The present invention has been made to solve the above problems.

本考案は定規にピンホール効果が生じる複数の光透過部を設けたものである。また、広範囲にわたる光透過部や、複数サイズの光透過部を有する。  The present invention provides a ruler with a plurality of light transmitting portions that produce a pinhole effect. Moreover, it has a light transmission part covering a wide range and a plurality of sizes of light transmission parts.

定規にピンホール効果が生じる光透過部があるので、普段は定規として使用でき、必要なときのみピンホール眼鏡として使用することができる。定規型のため筆記用具として携帯することができ、板書をする際は常に手元に置いておくことができる。
通常のピンホール眼鏡と違い、フレームがないので、眼鏡の上から使用することもできる。さらに定規の長さを活かし、広範囲にわたって複数の光透過部を設けることにより、顔のサイズに関係なく使用することが可能である。
また、定規の長さを活かし、複数サイズの光透過部を設けることも可能である。そうすることにより、部屋の明暗に応じて、一番よく見えるサイズの光透過部を選択して使用することができる。
Since the ruler has a light transmission part that produces a pinhole effect, it can be used as a ruler in general and can be used as pinhole glasses only when necessary. Because it is a ruler type, it can be carried as a writing instrument, and can always be kept at hand when writing on a board.
Unlike normal pinhole glasses, it has no frame and can be used from above the glasses. Furthermore, by utilizing the length of the ruler and providing a plurality of light transmitting portions over a wide range, it can be used regardless of the size of the face.
In addition, it is possible to provide a plurality of sizes of light transmitting portions by taking advantage of the length of the ruler. By doing so, it is possible to select and use the light transmitting portion having the size that can be best seen according to the brightness of the room.

図1は、本考案の第1実施形態の正面図である。FIG. 1 is a front view of a first embodiment of the present invention. 図2は、本考案の第2実施形態の正面図である。FIG. 2 is a front view of a second embodiment of the present invention.

以下、本考案を実施するための形態について説明する。
本考案は第1実施形態(図1)のように、定規にピンホール効果の生じる複数の光透過部を設けた形態である。
ピンホール効果が生じる範囲であれば、本考案は効果を発揮するが、ピンホール効果は瞳孔の大きさより小さい径でないと十分な効果を発揮しないことから、光透過部の直径は4ミリメートル以下であることが望ましい。
なお、光透過部の形状は略円形状としているが、これには真円も含まれる。また、円形に近い多角形や、略円形状を主体とした形状も含まれるものとする。
なお、略円形状以外の形状の場合、その形状の内側に接するように円形を描いた場合における円形の直径が4ミリメートル以下となっていればよい。
また、本考案は長手方向において両端に位置する光透過部の距離が4センチメートル以上であることが望ましい。
このようにして光透過部を広範囲にわたって設けることにより、顔のサイズに関係なく使用できるといった効果が生じる。
Hereinafter, the form for implementing this invention is demonstrated.
As in the first embodiment (FIG. 1), the present invention is a form in which a ruler is provided with a plurality of light transmitting portions that produce a pinhole effect.
The present invention is effective within the range where the pinhole effect occurs. However, since the pinhole effect is not effective unless the diameter is smaller than the size of the pupil, the diameter of the light transmitting portion is 4 mm or less. It is desirable to be.
In addition, although the shape of the light transmission part is substantially circular, this includes a perfect circle. Further, a polygon that is close to a circle or a shape that is mainly circular is included.
In the case of a shape other than a substantially circular shape, the diameter of the circle in a case where a circle is drawn so as to be in contact with the inside of the shape only needs to be 4 mm or less.
In the present invention, it is preferable that the distance between the light transmitting portions located at both ends in the longitudinal direction is 4 centimeters or more.
By providing the light transmission part over a wide range in this way, there is an effect that it can be used regardless of the size of the face.

また、第2実施形態(図2)のようにサイズの異なる光透過部を有する構造であってもよい。このようにサイズの異なる複数の光透過部を設けることにより、部屋の明暗に応じて、一番よく見えるサイズの光透過部を選択して使用することができる。  Moreover, the structure which has the light transmissive part from which size differs like 2nd Embodiment (FIG. 2) may be sufficient. By providing a plurality of light transmitting portions having different sizes as described above, it is possible to select and use a light transmitting portion having a size that can be best seen according to the brightness of the room.

また。本考案にある光透過部は、請求項2にあるように物理的に孔をあけたものだけでなく、光が一部透過するようにして孔と同様の効果を持たせた透明部分を有する構造であってもよい。このように実際に孔をあけるのではなく、透明部分を設けて光が透過する疑似的な孔にすることにより、孔を複数あけた場合における定規の耐久性低下の防止や、物理的に孔をあける場合と比べて製造コストを下げることができる等のメリットがある。  Also. The light transmitting portion according to the present invention has not only a physically perforated hole as in claim 2 but also a transparent portion that has the same effect as the hole so that a part of the light is transmitted. It may be a structure. Instead of actually drilling holes in this way, by providing a transparent part and making it a pseudo hole through which light is transmitted, the durability of the ruler can be prevented from decreasing when multiple holes are drilled, There is an advantage that the manufacturing cost can be reduced as compared with the case of opening.

定規の材質は透明で光をよく通すもの以外なら使用可能である。また、透明で光をよく通す材質であっても、塗装やプリント加工や間に光を通さない材質のものを挟むなどして、光透過部の周りにおいて、光が透過しない構造(遮光部)となっていればよい。材質の例として、例えばプラスチック、金属、木、紙等が考えられる。
なお、遮光部は光を完全に遮断する必要はなく、光透過部との対比においてピンホール効果を生じさせる程度の光の透過は許容できるものとする。
The ruler can be used as long as it is transparent and does not transmit light well. In addition, even if it is a transparent material that allows light to pass through, a structure that does not transmit light around the light transmitting part (such as a light shielding part), such as by painting or printing, or by interposing a material that does not transmit light in between. It only has to be. Examples of materials include plastic, metal, wood, paper, and the like.
Note that the light-shielding portion does not need to completely block light, and light transmission to the extent that causes a pinhole effect in comparison with the light-transmitting portion is acceptable.

本考案を使用するときは、眼または眼鏡の上に本考案をあて、光透過部を覗いて使用する。
通常は定規を横にして両方の眼で覗き両眼で使用するが、縦にして片方の眼で覗くことにより単眼での使用も可能である。
When the present invention is used, the present invention is placed on the eye or the spectacles and used by looking through the light transmitting portion.
Usually, the ruler is placed sideways and used with both eyes, but it can also be used with a single eye by looking vertically with one eye.
