本考案は前照灯に関するものであり、詳細にはＶＨＡＤ（ビークル・ヘッドラ ンプ・エーミング・デバイス）と称され外部から照準装置を使用することなしに 照準が行えるように前照灯自身に照準装置が組込まれた前照灯の照準装置を読取 るために設けられる覗窓に係るものである。 The present invention relates to a headlight, and more specifically, it is referred to as a VHAD (Vehicle Headlamp Aiming Device), and an aiming device is provided to the headlight itself so that aiming can be performed without using an aiming device from the outside. The present invention relates to a viewing window provided for reading a sighting device of a headlight having a built-in.

従来のこの種の覗窓９０の構成を示すものが図３、図４であり、ハウジング８ ０には外側に突出する枠部９１ａを設けた例えば円形の開口部９１を形成してお くと同時に適宜個所例えば３箇所にボス９２を設けておき、前記開口部９１には 例えば透明樹脂で形成された窓ガラス９３を前記ボス９２を利用して螺着するも のとされ、このときに前記開口部９１と窓ガラス９３との気密性を確保するため に前記窓ガラス９３のハウジング８０側となる周縁の位置にはガスケット溝９３ ａが設けられて、例えばゴム部材など柔軟な部材で形成されたシールガスケット ９４が嵌着され、前記した螺子９５による螺着により前記枠部９１ａと窓ガラス ９３とで前記シールガスケット９４を圧縮して挟持し気密構造とするものとされ ている。 FIGS. 3 and 4 show the structure of a conventional viewing window 90 of this type. For example, a circular opening 91 provided with a frame portion 91a protruding outward is formed in the housing 80. At the same time, it is said that bosses 92 are provided at appropriate places, for example, three places, and a window glass 93 formed of, for example, a transparent resin is screwed into the opening 91 by using the bosses 92. In order to ensure the airtightness between the opening 91 and the window glass 93, a gasket groove 93a is provided at a peripheral edge of the window glass 93 on the side of the housing 80, and is formed of a flexible member such as a rubber member. The sealing gasket 94 is fitted and the sealing gasket 94 is compressed and sandwiched between the frame portion 91a and the window glass 93 by the screwing with the screw 95 to form an airtight structure.

しかしながら、前記した従来の構成の覗窓９０においては、その取付作業時に 例えば３個所の螺子９５の螺着と云う大変に手間の係る作業を必要とするものと 成る。 However, the viewing window 90 having the above-described conventional structure requires a very troublesome work such as screwing the three screws 95 at the time of its mounting work.
【０００４】 また、もしも前照灯の出荷検査などで内蔵された照準装置が所定値を表示しな いときには前記覗窓９０の窓ガラス９３を取り外して照準装置の再調整を行う必 要があり、この場合に前記した構成の覗窓９０では取付け、取外しの作業が一層 に手間の係るものとなり、前照灯製造ラインにおける作業効率を阻害すると云う 問題点を生じ、この点の解決が課題とされるものとなっていた。Further, if the built-in sighting device does not display a predetermined value at the time of shipping inspection of the headlight, it is necessary to remove the window glass 93 of the peep window 90 and readjust the sighting device. In this case, in the sight glass 90 having the above-described configuration, the work of mounting and dismounting becomes more troublesome, and there arises a problem that the work efficiency in the headlamp manufacturing line is hindered, and the solution of this point becomes a problem. It was supposed to be done.

本考案は前記した従来の課題を解決するための具体的手段として、灯具内に内 蔵される照準装置の目盛を読み取るためにハウジングに設けられる開口部に透明 部材で形成された窓ガラスがシールガスケットを挟持して気密構造として取付け られて成る灯具内蔵型照準装置の覗窓において、前記開口部の縁部に突出されて 設けられる枠部の側面には係着溝が形成され、前記窓ガラスの外縁の適宜位置に は前記係着溝に係着するフック部が設けられ前記シールガスケットをこのフック 部の弾性により前記枠部と前記窓ガラスとで挟持し気密構造としたことを特徴と する灯具内蔵型照準装置の覗窓を提供することで、取付作業を容易なものとして 課題を解決するものである。 As a concrete means for solving the above-mentioned conventional problems, the present invention seals a window glass formed of a transparent member in an opening provided in a housing for reading a scale of an aiming device housed in a lamp. In a viewing window of a sighting device with a built-in lamp, which is sandwiched with a gasket and is attached as an airtight structure, an engaging groove is formed on a side surface of a frame portion projecting from an edge portion of the opening, and the window glass is provided. A hook portion that engages with the engagement groove is provided at an appropriate position on the outer edge of the seal gasket, and the seal gasket is sandwiched between the frame portion and the window glass by the elasticity of the hook portion to form an airtight structure. By providing a sight glass of a sighting device with a built-in lamp, the problem is solved by making the mounting work easy.

つぎに、本考案を図に示す一実施例に基づいて詳細に説明する。図１及び図２ に符号１で示すものは本考案に係る覗窓であり、この覗窓１はハウジング１０に 設けられた開口部２に窓ガラス３をシールガスケット４を挟持するように取付け 、これにより気密構造としている点は従来例のものと同様であるが、本考案によ り前記窓ガラス３は従来例のもののように螺着されることはなく、窓ガラス３自 身に係着構造が設けられるものとされ、これにより取付工程の簡素化が可能なも のとされている。 Next, the present invention will be described in detail based on an embodiment shown in the drawings. Reference numeral 1 in FIGS. 1 and 2 is a peep window according to the present invention. The peep window 1 has a window glass 3 attached to an opening 2 provided in a housing 10 so as to sandwich a seal gasket 4. The airtight structure is similar to that of the conventional example, but according to the present invention, the window glass 3 is not screwed like the conventional example, but is attached to the window glass 3 itself. It is supposed that a structure will be provided, which will simplify the mounting process.
【０００７】 以下に本考案の構成を更に詳細に説明すれば、先ず、前記ハウジング１０に設 けられる開口部２は例えば四角形など適宜な形状に形成され、その枠部２ａの外 側の側面、好ましくは全周に巡るように前記窓ガラス３と平行する係着溝２ｂが 設けられるものとされている。The structure of the present invention will be described in more detail below. First, the opening 2 provided in the housing 10 is formed in an appropriate shape such as a quadrangle, and the frame 2a has an outer side surface, Preferably, an engaging groove 2b is provided so as to extend around the entire circumference and parallel to the window glass 3.
【０００８】 また、前記窓ガラス３は前記開口部２に対応する形状とされ、そのハウジング １０側と成る周縁にはガスケット溝３ａが形成され、ゴム部材などで形成された シールガスケット４が嵌着されるものとされている点は従来例と同様であるが、 従来例で行われていた螺着用の孔などは設けられない。Further, the window glass 3 has a shape corresponding to the opening 2, a gasket groove 3 a is formed on a peripheral edge thereof on the housing 10 side, and a seal gasket 4 formed of a rubber member or the like is fitted therein. However, the holes for screwing, which are performed in the conventional example, are not provided.
【０００９】 従来の螺着に換えて本考案が採用するものが前記窓ガラス３に設けたフック部 ３ｂであり、このフック部３ｂは前記窓ガラス３の周縁が例えば各辺に１箇所な ど適宜位置で前記開口部２の枠部２ａと平行となり且つ先端に前記係着溝２ｂと 係着するフック３ｃが形成されて成るものとされている。What is adopted by the present invention in place of the conventional screwing is a hook portion 3b provided on the window glass 3, and the hook portion 3b has, for example, one edge on each side of the window glass 3. A hook 3c which is parallel to the frame portion 2a of the opening portion 2 at an appropriate position and which engages with the engaging groove 2b is formed at the tip.
【００１０】 このように構成された本考案の覗窓１は、前記開口部２の枠部２ａ上の所定位 置に、シールガスケット４をガスケット溝３ａに嵌着した窓ガラス３を載置し、 この後に前記窓ガラス３を更に押圧することで前記シールガスケット４はその弾 性により圧縮され、フック部３ｂが係着溝２ｂに係着し、窓ガラス３の固定が行 われるものとなる。In the sight glass 1 of the present invention having the above-described structure, the window glass 3 having the seal gasket 4 fitted in the gasket groove 3a is placed at a predetermined position on the frame portion 2a of the opening 2. After that, by further pressing the window glass 3, the seal gasket 4 is compressed by its elasticity, the hook portion 3b is engaged with the engagement groove 2b, and the window glass 3 is fixed.
【００１１】 尚、このときに前記窓ガラス３を例えばポリカーボネート樹脂など高弾性で且 つ容易に切損を生じない部材で形成しておくことが好ましい。また、前記係着溝 ２ｂとフック部３ｂとの係着の解除を専用工具を使用しないかぎり困難と成るよ うにフック部３ｂの配置などを工夫しておけば、市場において不用意に窓ガラス ３が外され、前記した照準器が狂わされるなどの事故の防止が図れるものとなり 、性能の保証の面から好ましいものとなる。At this time, it is preferable that the window glass 3 is formed of a member such as a polycarbonate resin having high elasticity and not easily cut. Moreover, if the hook portion 3b is arranged so that it is difficult to release the engagement between the engagement groove 2b and the hook portion 3b unless a special tool is used, the window glass 3 will be carelessly placed on the market. It is possible to prevent accidents such as the sighting device being out of order, which is preferable in terms of performance guarantee.
【００１２】[0012]
以上に説明したように本考案により、開口部の縁部に突出されて設けられる枠 部の側面には係着溝が形成され、窓ガラスの外縁の適宜位置には前記係着溝に係 着するフック部が設けられ、シールガスケットをこのフック部の弾性により前記 枠部と前記窓ガラスとで圧縮挟持した構成の灯具内蔵型照準装置の覗窓としたこ とで、窓ガラスの押圧と言う極めて単純な工程で取付を可能なものとすると共に 部品点数も少なくし、生産性の向上とコストダウンとに極めて優れた効果を奏す るものである。 As described above, according to the present invention, the engaging groove is formed on the side surface of the frame portion protruding from the edge of the opening, and the engaging groove is attached to the outer edge of the window glass at an appropriate position. A window part of a sighting device with a built-in lamp that is provided with a hook portion that is compressed and sandwiched between the frame portion and the window glass by the elasticity of the hook portion is referred to as pressing of the window glass. This makes it possible to install in an extremely simple process and reduces the number of parts, resulting in an extremely excellent effect on productivity improvement and cost reduction.
