以下、本発明の光センサ検査冶具の一実施形態について図面に基づき説明する。
図１は、本実施形態の光センサ検査冶具による検査の対象である照明設備１に設置された光センサを示す図である。同図に示すように、光センサ２は、地上から非常に高い位置に取り付けられている。照明装置１は、光センサ２により周囲の明るさが一定以上であると感知された場合には照明３を消灯し、周囲の明るさが一定以上ではないと感知された場合には照明３を点灯する。 Hereinafter, an embodiment of an optical sensor inspection jig according to the present invention will be described with reference to the drawings.
FIG. 1 is a diagram illustrating an optical sensor installed in a lighting facility 1 that is an object of inspection by the optical sensor inspection jig of the present embodiment. As shown in the figure, the optical sensor 2 is mounted at a very high position from the ground. The illumination device 1 turns off the illumination 3 when the light sensor 2 senses that the ambient brightness is above a certain level, and turns off the illumination 3 when it is sensed that the ambient brightness is not above a certain level. Light.

図２は、本実施形態の光センサ検査冶具１０の正面図であり、（Ａ）は収容部１１の入口部１４が閉じた状態を、（Ｂ）は入口部１４が開いた状態を示す。また、図３は、図２（Ａ）における収容部１１のIII−IIIにおける水平断面図である。図２及び図３に示すように光センサ検査冶具１０は、長尺棒１２と、長尺棒１２の先端に取り付けられた収容部１１とを備える。長尺棒１２は、軸方向に互いに接続され、先端にいくほど小径となる複数の筒状部材１３から構成されている。長尺棒１２は、図４に示すように、筒状部材１３が入れ子状に互いに収納されることにより、長さを調節することができる。また、筒状部材１３は絶縁体により形成されており、点検作業時の感電事故を防止することができる。 2A and 2B are front views of the optical sensor inspection jig 10 of the present embodiment, in which FIG. 2A shows a state in which the inlet portion 14 of the accommodating portion 11 is closed, and FIG. 2B shows a state in which the inlet portion 14 is opened. FIG. 3 is a horizontal sectional view taken along the line III-III of the accommodating portion 11 in FIG. As shown in FIGS. 2 and 3, the optical sensor inspection jig 10 includes a long bar 12 and a housing portion 11 attached to the tip of the long bar 12. The long bar 12 is composed of a plurality of cylindrical members 13 that are connected to each other in the axial direction and have a smaller diameter toward the tip. As shown in FIG. 4, the long bar 12 can be adjusted in length by accommodating the cylindrical members 13 in a nested manner. Moreover, the cylindrical member 13 is formed with the insulator, and can prevent the electric shock accident at the time of inspection work.

収容部１１は、布袋１５と一対の板材１６とで構成される。布袋１５は、遮光性を有する袋状の布からなり、入口部１４が設けられている。一対の板材１６はこの入口部１４の縁に取り付けられている。一対の板材１６は、ステンレス等の弾性変形可能な部材からなり、互いに密着した状態で両端部を接着剤により接合されている。このため、一対の板材１６に両端部が引き寄せられる方向に荷重が作用させると、図２（Ｂ）に示すように板材１６が外側方向に撓むことにより、収容部１１の入口部１４を開くことができる。また、この荷重を取り除くと、板材１６が元の形状に戻るため、入口部１４を閉じることができる。 The accommodating portion 11 is composed of a cloth bag 15 and a pair of plate members 16. The cloth bag 15 is made of a bag-shaped cloth having a light shielding property, and is provided with an inlet portion 14. The pair of plate members 16 are attached to the edge of the inlet portion 14. A pair of board | plate materials 16 consist of elastically deformable members, such as stainless steel, and both ends are joined by the adhesive agent in the state which mutually contact | adhered. For this reason, when a load is applied to the pair of plate members 16 in the direction in which both end portions are drawn, the plate member 16 bends outward as shown in FIG. 2B, thereby opening the inlet portion 14 of the housing portion 11. be able to. Further, when this load is removed, the plate member 16 returns to its original shape, so that the inlet portion 14 can be closed.

また、光センサ検査冶具１０は、その一端が板材１６の上端の接合部に接続され、長尺棒１２の内部を通り、その他端は握り手部１８まで延びる紐１７を備える。この紐１７を引張ることにより、板材１６に両端部が引き寄せられる方向に荷重が作用するため、紐１７を操作することにより収容部１１の入口部１４を開閉させることができる。なお、紐１７と板材１６との接続は、例えば、板材１６の上端の接合部にリング状の金具を取り付け、このリング状の金具に紐１７を結びつけることにより行ってもよい。 The optical sensor inspection jig 10 includes a string 17 having one end connected to the joint at the upper end of the plate member 16, passing through the inside of the long bar 12, and the other end extending to the grip portion 18. By pulling the string 17, a load acts in a direction in which both end portions are drawn toward the plate material 16, so that the entrance part 14 of the housing part 11 can be opened and closed by operating the string 17. The string 17 and the plate material 16 may be connected by, for example, attaching a ring-shaped metal fitting to the joint at the upper end of the plate material 16 and tying the string 17 to the ring-shaped metal fitting.

次に、光センサ検査冶具１０を用いた光センサ２の検査方法について説明する。
まず、周囲が明るい状態で、照明３が点灯していないことを確認した後に、紐１７を引張ることにより入口部１４を開きながら、入口部１４より光センサ２が収容部１１内に入るように光センサ検査冶具１０を動かす。この際、光センサ２の設置されている高さに合わせて、長尺棒１２の長さを伸縮させることができる。光センサ２が収容部１１内に収容できたら入口部１４を閉じる。入口部１４を閉じることにより収容部１１内への光の入射が遮断されるため、収容部１１内が暗い状態になる。この時、照明３が消えれば光センサ２が正常であり、消えなければ光センサ２が故障していると判断できる。 Next, an inspection method for the optical sensor 2 using the optical sensor inspection jig 10 will be described.
First, after confirming that the illumination 3 is not turned on in a bright state, the optical sensor 2 enters the accommodating portion 11 from the inlet portion 14 while opening the inlet portion 14 by pulling the string 17. The optical sensor inspection jig 10 is moved. At this time, the length of the long bar 12 can be expanded and contracted according to the height at which the optical sensor 2 is installed. When the optical sensor 2 can be accommodated in the accommodating part 11, the inlet part 14 is closed. Since the entrance of the entrance portion 14 blocks the incidence of light into the housing portion 11, the interior of the housing portion 11 becomes dark. At this time, it can be determined that the light sensor 2 is normal if the illumination 3 is turned off, and that the light sensor 2 is broken if the light 3 is not turned off.

本実施形態の光センサ検査冶具１０によれば、以下の効果が得られる。
収容部１１を布袋１５と板材１６だけからなる単純な構成としたため、低コストで製作することができる。また、各部材が軽量であるため、点検作業や持ち運びが容易になる。
また、長尺棒１２が伸縮自在に構成されており、光センサ２の高さに合わせて長尺棒１２の長さを調整したり、長尺棒１２を縮めてコンパクトな状態で持ち運んだりすることができ、作業性を向上できる。また、長尺棒１２が絶縁体で形成されているため、感電事故を防止することができる。 According to the optical sensor inspection jig 10 of the present embodiment, the following effects can be obtained.
Since the accommodating portion 11 has a simple configuration including only the cloth bag 15 and the plate material 16, it can be manufactured at low cost. Moreover, since each member is lightweight, inspection work and carrying are easy.
Further, the long bar 12 is configured to be extendable and retractable, and the length of the long bar 12 is adjusted according to the height of the optical sensor 2, or the long bar 12 is contracted and carried in a compact state. And workability can be improved. Moreover, since the long bar 12 is formed of an insulator, an electric shock accident can be prevented.

また、本実施形態では、一対の板材を紐で引くことにより入口部の開閉を行う構成としたが、これに限らず、例えば、入口部に暖簾状に垂れ下がる布を設けることにより、光を遮断する構成としてもよい。かかる構成でも、光センサを内部に収容した状態で内部に入射する光を遮断することができるため、光センサの点検を容易に行うことができる。 The optical sensor inspection jig of the present invention is not limited to the above embodiment.
In the present embodiment, as a means for opening and closing the entrance portion, a string connected to the upper end of the plate material and extending to the grip portion is provided, but not limited to this, a striated body such as a wire or a fishing line may be used. .
In this embodiment, the entrance portion is opened and closed by pulling a pair of plate members with a string. However, the present invention is not limited to this. For example, by providing a cloth that hangs in a warm manner at the entrance portion, light is blocked. It is good also as composition to do. Even in such a configuration, it is possible to block the light incident on the optical sensor in a state in which the optical sensor is accommodated therein, so that the optical sensor can be easily inspected.
