Description

【０００１】
【発明の属する技術分野】
本発明は、防水型誘導灯に関するものである。
【０００２】
【従来の技術】
一般に、誘導灯は、少なくとも一面側に開口した器具本体の内部に、ランプを装着するためのソケットや、蓄電池、停電検出回路や充電回路を含む誘導灯ブロック、及び点灯装置等の点灯用部品を収容させ、器具本体の開口側に透光性部材である樹脂製の表示板が取り付けられた枠体を、開口を塞ぐように装着させて構成されている。そして、平常時は、商用電源に接続されて蓄電池が充電回路を介して充電されると共に、ランプが商用電源により点灯されており、停電時には、停電検出回路が停電を検出して蓄電池によりランプを少なくとも所定時間点灯させるようにされ、ランプからの光が表示板を透過して器具本体の外側に放出されて、その表示板により避難口等を表示させるようにされている。
【０００３】
このような誘導灯は、浴室や、厨房などの湿気の多い場所や雨水が直接かかるところでも、一般屋内に比べて頻度は低いものの使用され、このような場合においては、従来から防水型誘導灯が使用されている。このような従来の防水型誘導灯は、器具本体に収容される点灯用部品であるソケットや、蓄電池、誘導灯ブロック、及び点灯装置等の点灯用部品を、それぞれが防水、防湿構造を有するように例えばパッキン等を用いて構成した防水型部品とし、それらの防水型部品を接続部の防水性を確保しながら器具本体内で電気的に接続させて、その状態で防水、防湿性能が確保されるようにされている。また、器具本体の開口側には、上述の場合と同様に、透光性部材である樹脂製の表示板が脱落しない程度に取り付けられた枠体が、例えば器具本体を外装するように係合して、器具本体に係脱自在とされている。
【０００４】
【発明が解決しようとする課題】
しかしながら、このように構成された従来の防水型誘導灯においては、枠体と表示板の間や、枠体と器具本体の間に隙間が存在し、器具本体内には雨水や湿気が浸入するため、全ての点灯用部品を防水型部品とする必要があり、一般屋内用の非防水の誘導灯の点灯用部品を流用できず、一般屋内用の点灯用部品に加えて、使用頻度の低い防水型の誘導灯の点灯用部品を別部品として製造する必要があって、部品管理も煩雑となりコストも高くなるという問題点があった。
【０００５】
本発明は、上記問題点に鑑みてなされもので、その目的とするところは、点灯用部品を防水型とすることなく、防水、防湿性能を確保した安価な防水型誘導灯を提供することにある。
【０００６】
【課題を解決するための手段】
本発明は上記の問題点を解決するため、請求項１記載の発明にあっては、内部に蓄電池１ａや誘導灯ブロック１ｂを含む点灯用部品１とランプ２が収容され少なくとも一面が開口すると共にこの開口３ａの周方向に連続した側壁３ｂを有してなる器具本体３と、この器具本体３の開口３ａ側に取り付けられて中央側に前記器具本体３の開口３ａの前面側に位置する透光開口４ａが設けられた枠体４と、この枠体４の透光開口４ａを塞ぐように前記器具本体３側から装着される透光部材製の表示板５とを備えてなる防水型誘導灯において、前記表示板５の周端部に、内周側に前記表示板５の周端部が嵌合される周溝６ａが形成された防水パッキン６を装着させ、この防水パッキン６を前記枠体４と前記器具本体３の開口周縁部３ｃの間で全周にわたって挟持させると共に、前記器具本体３の側壁３ｂを、略筒状の内壁部３ｅと、この内壁部３ｅと隙間３ｆを介して対向し隙間３ｆと器具本体３の外部とを連通させる水抜き孔３ｇが設けられた外壁部３ｈとを備えた二重壁に形成し、前記枠体４を、前記透光開口４ａが設けられた枠本体部４ｂと、この枠本体部４ｂの周端全周から前記器具本体３側に立設された周壁部４ｃとを備えて前記透光開口４ａの周端での断面が略Ｌ字状をなすように形成すると共に、前記枠体４の略Ｌ字状をなす内側角部に沿って前記防水パッキン６を配設し、この防水パッキン６を前記内壁部３ｅの先端と枠本体部４ｂの間で挟持させて前記器具本体３を密閉させ、前記外壁部３ｈの先端に前記枠体４の周壁部４ｃの先端を略対向させて配設したことを特徴とするものである。
【００１１】
【発明の実施の形態】
図１及び図２は、本発明の防水型誘導灯の第１の参考例を示すものであり、この防水型誘導灯は、蓄電池１ａや誘導灯ブロック１ｂを含む点灯用部品１と、器具本体３、枠体４、表示板５、及び防水パッキン６とを有して構成されており、ランプ２として冷陰極ランプが装着できるようにされている。
【００１２】
点灯用部品１は、蓄電池１ａと、商用電源に接続され充電回路を備えて平常時には蓄電池１ａを充電させると共に、停電時には停電を検出して蓄電池１ａによりランプ２を少なくとも所定時間点灯させるための誘導灯ブロック１ｂのほかに、図示はしないが、ランプ２を保持するための一対のソケットや、ランプ２を点灯させるための点灯装置等を備えている。
【００１３】
器具本体３は、例えば金属ダイカスト製で一面側が開口した有底の略箱状をなし、底部３ｋの周端から略角筒状をなす側壁３ｂを立設させ、その側壁３ｂの先端側が開口３ａとされており、その開口周縁部３ｃは、側壁３ｂの先端が開口３ａの中心側に向かって突出するように内鍔状の鍔部３ｄが形成されている。また、器具本体３開口３ａ側の角部近傍には、枠体４をねじ止めするためのねじ穴３ｍが、器具本体３の内部に貫通することがないように設けられている。なお、図示はしないが、器具本体には電源線の挿入孔も設けられており、その挿入孔はパッキン等により密閉されて防湿、防水性が確保されるようにされている。
【００１４】
枠体４は、例えば金属ダイカスト製で器具本体３の開口３ａ側に取り付けられるものであって、器具本体３に当接する側の大きさが、器具本体３と略同じ大きさとされており、略平板状の中央側に透光開口４ａが設けられた枠本体部４ｂと、この枠本体部４ｂの周端全周に立設された周壁部４ｃとを備えて、透光開口４ａの周縁の断面が略Ｌ字状をなすように形成されている。また、枠本体部４ｂの角部近傍であって、器具本体３のねじ穴３ｍと対向する部位には、ねじ挿通孔４ｄが設けられている。
【００１５】
表示板５は、透光性部材である例えば合成樹脂製であって平板状に形成され、表面には表示模様５ａが描かれており、少なくとも枠体４の透光開口４ａよりも大きく枠本体部４ｂよりも小さい寸法を有し、枠体４の周壁部４ｃの先端側から枠体４に取り付けられる。
【００１６】
防水パッキン６は、弾性部材である例えばゴム製であって、枠体４の周壁部４ｃの内側に略当接するように配設される略四角形のループ状に形成されてなり、その内周側に表示板５の周端部が嵌合される周溝６ａが形成されて構成されている。また、その厚みは、一面側が枠本体部４ｂに当接した状態で、他面側が枠体４の周壁部４ｃよりも突出する寸法を有するようにされている。
【００１７】
このように構成された防水型誘導灯では、透光開口４ａを塞ぐように表示板５が防水パッキン６を介して装着された枠体４が、蓄電池１ａ、誘導灯ブロック１ｂ等の点灯用部品１やランプ２等を収容した器具本体３の開口３ａ側に、周壁部４ｃの先端が器具本体３の開口周縁部３ｃを形成する鍔部３ｄの基端側に対向して略当接するように、つまり、周壁部４ｃと器具本体３の側壁３ｂの外面が略面一となるように配設されて、ねじ挿通孔４ｄに挿入されたねじ７により締めつけられて取り付けられるようにされている。このとき、器具本体３の内部の空間は、防水パッキン６が器具本体３の開口周縁部３ｃである鍔部３ｄと枠体４の枠本体４ｂとの間で押圧されて弾性変形することにより密閉性を保つようにされて、防湿、防水性能を確保するようにされている。
【００１８】
このように構成されているため、本参考例における防水型誘導灯においては、表示板５の周端が周溝６ａに挿入された防水パッキン６が、器具本体３の開口周縁部３ｃと枠体４との間で押圧されて器具本体３の密閉性を保つため、一般屋内用の表示板５を流用でき、また、防水型でない一般屋内用の誘導灯に使用する蓄電池１ａや誘導灯ブロック１ｂ等の点灯用部品１を使用しても防湿、防水性能を確保することができる。このため、防水型の点灯用部品１を製造する必要がなくなって、コストダウンが図れる。また、防水パッキン６は、器具本体３側では、その開口周縁部３ｃに設けられた鍔部３ｄに略全面にわたって当接しているため、防水パッキン６と器具本体３の間の当接面積が大きくなって、より確実に密閉性を確保することができる。さらには、枠体４を、透光開口４ａが設けられる枠本体部４ｂと、この枠本体部４ｂの周端全周から器具本体３側に立設された周壁部４ｃとを備えて断面が略Ｌ字状をなすように形成し、枠体４の略Ｌ字状をなす内側角部に略沿って防水パッキン６を配設させたため、防水パッキン６の位置決めがし易く、誘導灯の製造がし易くなる。また、枠体４の周壁部４ｃの先端が器具本体３の開口周縁部３ｃを形成する鍔部３ｄである内鍔の基端側に略当接するように、つまり、周壁部４ｃが鍔部３ｄ上であって開口３ａ側と反対側の外側に当接して、周壁部４ｃと器具本体３の側壁３ｂの外面が略面一となるように配設されているため、器具本体３と枠体４が略当接する防水型誘導灯の外面にほとんど凹凸がなくなって、見栄えが良くなる。
【００１９】
なお、図２は、本参考例における防水型誘導灯の変形例を示すもので、器具本体３の開口周縁部３ｃに設けた鍔部３ｄを、図１に示す内鍔に代えて外鍔とした点であり、このように構成しても外形に凹凸が生ずるものの、図１に示す防水型誘導灯と略同様の効果を奏する。
【００２０】
図３は、本発明の防水型誘導灯の実施の形態の要部を示すものであり、前記参考例と異なる点は、器具本体３であり、他は前記参考例と同様に構成されている。
【００２１】
器具本体３は、例えば一面側が開口した有底の略箱状であって、底部３ｋの周端に略角筒状をなす側壁３ｂが立設されて、その側壁３ｂの先端側に開口するように形成されており、その側壁３ｂが、略筒状の内壁部３ｅと、この内壁部３ｅの外側に隙間３ｆを介して対向すると共に、隙間３ｆと器具本体３の外部とを連通させる複数の水抜き孔３ｇが設けられた外壁部３ｈとを備えた二重壁とされて構成されている。
【００２２】
そして、器具本体３の外壁部３ｈの先端には、枠体４の周壁部４ｃの先端が対向して略当接するように配設されて、防水型誘導灯の外面では器具本体３と枠体４の外面が面一となるようにされている。また、開口周縁部３ｃである内壁部３ｅの先端には、枠体４の略Ｌ字状をなす内側角部に配設された防水パッキン６が当接するようにされており、内壁部３ｅの先端と枠本体部４ｂの間で挟持された防水パッキン６により、密閉性が確保されるようにされている。また、枠体４の周壁部４ｃの先端と器具本体３の外壁部３ｈの先端の間から隙間３ｅ側に浸入した水は、水抜き孔３ｇから器具本体３の外部に流れ出るようにされている。
【００２３】
このように構成されているため本実施の形態における防水型誘導灯においても、前記参考例と同様の効果を奏すると共に、器具本体３の開口周縁部３ｃに側壁３ｂと略垂直方向に突出する鍔部を設ける必要がないために、器具本体３が製造し易くなると共に、枠体４の周壁部４ｃの先端が、器具本体３の外壁部３ｈの先端に略当接するように対向して配設されて、枠体４の周壁部４ｃと器具本体３の側壁３ｂの外面が略面一となるように配設されているため、器具本体３と枠体４が略当接する防水型誘導灯の外面にほとんど凹凸がなくなって、見栄えを良くできる。
【００２４】
なお、以上、器具本体３を一面側に開口３ａを有するものとして説明を行ったが、本発明はこれに限らず、対向する両面に開口を備え、その両開口に表示板を有する枠体が装着されたような防水型誘導灯であっても良い。また、器具本体３、及び枠体４をそれぞれ金属製として説明を行ったが、本発明はこれに限らず、合成樹脂製であっても良いことは勿論である。
【００２５】
【発明の効果】
このように構成されているため本発明は、請求項１記載の発明にあっては、表示板の周端が周溝に挿入された防水パッキンが、器具本体の開口周縁部と枠体との間で押圧されて器具本体の密閉性を保つため、一般屋内用の表示板を流用でき、また、防水型でない一般屋内用の誘導灯に使用する蓄電池や誘導灯ブロック等の点灯用部品を使用して防湿、防水性能を確保することができる。このため、防水型の点灯用部品を製造する必要がなくなって、コストダウンが図れる。
【００２９】
さらに、器具本体の開口周縁部側に側壁と略垂直方向に突出する鍔部を設ける必要がないために、器具本体が製造し易くなると共に、枠体の周壁部の先端が、器具本体の外壁部の先端に略当接するように対向して配設されて、枠体の周壁部と器具本体の側壁である外壁部の外面が略面一となるように配設されているため、器具本体と枠体が略当接する防水型誘導灯の外面にほとんど凹凸がなくなって、見栄えを良くできる。

In the invention according to claim 1, the waterproof packing in which the peripheral edge of the display board is inserted into the peripheral groove is formed between the opening peripheral portion of the instrument body and the frame body. Because it is pressed between the two, the indoor indoor display panel can be diverted to maintain the sealing of the main body of the equipment, and lighting parts such as storage batteries and induction light blocks used for general indoor guide lights that are not waterproof are used. Thus, moisture resistance and waterproof performance can be secured. For this reason, it is not necessary to manufacture a waterproof lighting part, and the cost can be reduced.
[0029]
Furthermore, since it is not necessary to provide a flange that projects in a direction substantially perpendicular to the side wall on the peripheral edge side of the opening of the instrument body, the instrument body is easy to manufacture, and the distal end of the peripheral wall portion of the frame body is connected to the outer wall of the instrument body. The instrument main body is disposed so as to be substantially in contact with the tip of the part, and the outer surface of the outer wall part which is the side wall of the instrument body is substantially flush with the peripheral wall part of the frame body. The outer surface of the waterproof guide light with which the frame body substantially abuts is almost free of irregularities, so that the appearance can be improved.
