【考案の詳細な説明】
本考案は、開口部が小さく奥行が長くて照射光の入りに
くいパイプ状物体の内部、あるいは小さな隙間等の暗部
を観察するに好適な観察孔付携帯照明器具に関する。[Detailed Description of the Invention] The present invention relates to a portable lighting device with an observation hole suitable for observing the inside of a pipe-shaped object having a small opening and a long depth, making it difficult for irradiation light to enter, or dark areas such as small gaps.
例えば、暗い細管内を観察するには、従来比較的細身の
懐中電灯を用いてその目的を果すことが多かった。For example, to observe the inside of a dark tube, a relatively slender flashlight has traditionally been used.
第1図は、かかる従来の観察方法を示す概略図である。FIG. 1 is a schematic diagram showing such a conventional observation method.
すなわち、細管A内の物体Bを観察する場合、光源と観
察者の目の間に隔たりXがあるため、光の照射方向Cと
観察者の視線りとを一致させることは非常に困難であり
、このことは細管Aの直径が小さくなるにつれて、より
顕著になる。In other words, when observing an object B inside a thin tube A, there is a gap X between the light source and the observer's eyes, so it is extremely difficult to match the light irradiation direction C with the observer's line of sight. , this becomes more noticeable as the diameter of the capillary A becomes smaller.
さらに、光の照射量が弱くて奥深い部分の観察ができな
い等の欠点を有していた。Furthermore, it has the disadvantage that the amount of light irradiated is weak, making it impossible to observe deep parts.
本考案は、上記欠点に鑑みてなされたもので、暗い細管
の内部あるいは小さな隙間などの暗部内の観察が容易な
携帯照明器具を提供することを目的とするものである。The present invention has been made in view of the above-mentioned drawbacks, and it is an object of the present invention to provide a portable lighting device that allows easy observation of the inside of a dark tube or a dark area such as a small gap.
本考案にかかる観察孔付携帯照明器具は、光源と光源を
囲んで背面に反射鏡を有してなる頭部と、前記光源に電

るものである。A portable lighting device with an observation hole according to the present invention is composed of a light source, a head that surrounds the light source and has a reflecting mirror on the back, and a power supply section for supplying current to the light source, and the head is provided near the light source. The device is characterized in that an observation hole passing through the head is provided.
次に、本考案実施例について図面を参照しつつ説明する
。Next, embodiments of the present invention will be described with reference to the drawings.
第2図は、本考案の観察孔付携帯照明器具Eによる観察
状況を示す図であり、これは光源と観察者の目の間に存

照射方向と観察者の視線をほぼ一致させて、細管A内の
物体Bを観察しようとするものである。FIG. 2 is a diagram showing an observation situation using the portable lighting device E with an observation hole according to the present invention, in which the gap X between the light source and the observer's eyes is made substantially zero, and as shown in the figure. The object B in the thin tube A is to be observed by making the direction of light irradiation substantially coincide with the line of sight of the observer.
第3図および第4図は、第2図で示した観察孔付携帯照
明器具Eの具体的な構成例を示す平面図ならびに要部の
破断断面図である。3 and 4 are a plan view and a cutaway cross-sectional view of essential parts, respectively, showing a specific example of the configuration of the portable lighting device E with an observation hole shown in FIG. 2. FIG.
この観察孔付携帯照明器具は光源を有する頭部1と、こ
れに直交して設けられ頭部1の電源となる乾電池8を内
蔵する筒体2との2部分構成となっている。This portable lighting device with an observation hole has a two-part structure: a head 1 having a light source, and a cylindrical body 2 installed orthogonally thereto and containing a dry cell battery 8 serving as a power source for the head 1.
さらに頭部1は、第4図で示すようにその中央近傍に位
置する光源3とその背面に形成された反射鏡4と、前面
に設けられた透光板5とよりなっており、その光源の近
傍に遮蔽板6により光源3と隔てられて、はば光の照射
方向と平行になるように観察孔7が設けられている。Furthermore, as shown in FIG. 4, the head 1 consists of a light source 3 located near the center, a reflecting mirror 4 formed on the back of the head, and a transparent plate 5 provided on the front. An observation hole 7 is provided near the light source 3 and separated from the light source 3 by a shielding plate 6 so as to be parallel to the irradiation direction of the light.
この観察孔7は、反射鏡4を貫通して外部に通じており
、この観察孔7を通して外側から光源による照射方向を
観察することができるようになっている。This observation hole 7 passes through the reflecting mirror 4 and communicates with the outside, so that the direction of irradiation by the light source can be observed from the outside through this observation hole 7.
また、筒体2の内部には乾電池8が設置されている。Further, a dry battery 8 is installed inside the cylinder 2.
かかる構造をとることにより、光の照射方向と視線の方
向を第2図のごとくほぼ一致させることができるため、
細管の中等の暗部を確実にしかも深部にいたるまで観察
することができる上、従来の細身の懐中電灯を用いた場
合に比べて光の照射量も多くなり細部の観察も可能にな
る。By adopting such a structure, the direction of light irradiation and the direction of the line of sight can be made almost the same as shown in Fig. 2.
Not only can it reliably observe dark areas such as tubules, but also go deep, the amount of light irradiated is greater than when using a conventional slender flashlight, making it possible to observe fine details.
また、第5図は本考案の他の実施例を示す図である。Moreover, FIG. 5 is a diagram showing another embodiment of the present invention.
第5図に示すように頭部1′と筒体2′を連結部9を介
して結合し、この部分で折曲げを可能なものとなすこと
によって互いの角度を自在に選定しうるようにすると通
常と懐中電灯としても用いることができる。As shown in FIG. 5, the head 1' and the cylindrical body 2' are connected via a connecting part 9, and this part can be bent, so that the mutual angle can be freely selected. It can then be used as a regular flashlight.
以上説明してきたように、本考案の観察孔付携帯照明器
具は、細管の内あるいは、小さな隙間の奥の方に到るま
で明るい光を照射し、かつ観察が容易にできるものであ
り、その利用価値はすこぶる高い。As explained above, the portable lighting device with an observation hole of the present invention can emit bright light deep into a thin tube or a small gap, and can facilitate observation. The utility value is extremely high.
