Description

本発明は鉄道車両の車室内を照明するための灯具に関する。   The present invention relates to a lamp for illuminating a passenger compartment of a railway vehicle.

鉄道車両の客室には、一般に、その天井部に蛍光ランプを光源とする灯具が取り付けられ、その光源の蛍光ランプとしては直管が多用されており、蛍光ランプの両端を支持して給電する一対のランプソケット並びに安定器を備えた灯具本体が用いられる。また、この灯具本体に対して、照明光を和らげ、あるいは蛍光ランプの落下等を防止する目的で、蛍光ランプの下側を覆う灯具カバーを設ける場合がある。   In general, in a passenger room of a railway vehicle, a lamp having a fluorescent lamp as a light source is attached to a ceiling portion thereof, and a straight tube is frequently used as the fluorescent lamp of the light source, and a pair of power supplies is supported by supporting both ends of the fluorescent lamp. A lamp body having a lamp socket and a ballast is used. In addition, there is a case where a lamp cover that covers the lower side of the fluorescent lamp is provided on the lamp main body in order to soften the illumination light or prevent the fluorescent lamp from falling.

灯具カバーは、通常、蛍光ランプに沿った一方の側縁をヒンジを介して灯具本体に回動自在に支持するとともに、他方の側縁をラッチ機構を介して灯具本体に対して着脱自在に支持した構造のもとに灯具本体に装着され、ラッチ機構を外してヒンジを中心として回動させることによって灯具カバーを開き、蛍光ランプを交換できるようになっている。   The lamp cover normally supports one side edge along the fluorescent lamp rotatably on the lamp body via a hinge and the other side edge detachably supported on the lamp body via a latch mechanism. It is mounted on the lamp body under the structure described above, and the lamp cover can be opened by exchanging the latch mechanism and pivoting about the hinge so that the fluorescent lamp can be replaced.

また、このようなヒンジやラッチ機構を用いずに灯具カバーを開いて蛍光ランプの交換を可能とする灯具として、灯具カバーの両側縁にカバー支え具の基端を固着し、この各カバー支え具の先端にフック状の折り曲げ部を形成する一方、灯具本体の両側壁部にはカバー支え具の折り曲げ部を係合させる複数の開口部を形成したものが知られている（例えば特許文献１参照）。この構成により、各カバー支え具の折り曲げ部の灯具本体の開口部に対する係合を解くことにより、灯具カバーを灯具本体から取り外すことができ、蛍光ランプの交換作業を困難化することなく、ラッチ機構やヒンジを用いない分だけ低コスト化を達成している。
特開２００１−１８４９３１号公報 In addition, as a lamp that allows the fluorescent lamp to be replaced by opening the lamp cover without using such a hinge or a latch mechanism, the base ends of the cover support are fixed to both side edges of the lamp cover, and each cover support A hook-shaped bent portion is formed at the tip of the lamp, and a plurality of openings for engaging the bent portions of the cover support are formed on both side wall portions of the lamp body (see, for example, Patent Document 1). ). With this configuration, the lamp cover can be removed from the lamp body by releasing the engagement of the bent part of each cover support with the opening of the lamp body, and the latch mechanism can be performed without complicating the replacement work of the fluorescent lamp. The cost is reduced by not using a hinge or hinge.
JP 2001-184931 A

ところで、上記した特許文献１に記載の鉄道車両用灯具においては、灯具カバーの全体を灯具本体から取り外した後、その灯具カバーを一旦どこかに置いた状態で蛍光ランプを交換しなければならず、その作業が面倒であるという問題があり、また、ラッチ機構とヒンジを用いた通常の鉄道車両用灯具においては、灯具カバーの全体を取り外すことなく蛍光ランプの交換が可能であるものの、灯具カバー自体を交換したり、あるいは何らかの理由により灯具カバーの全体を取り外す必要のある場合には、ヒンジを取り付けているネジをドライバ等の工具を用いて外さなければならなず、その作業が煩雑であるという問題がある。   By the way, in the railcar lamp described in Patent Document 1 described above, after removing the entire lamp cover from the lamp body, the fluorescent lamp must be replaced with the lamp cover once placed somewhere. However, there is a problem that the work is troublesome, and in a normal railway vehicle lamp using a latch mechanism and a hinge, although it is possible to replace the fluorescent lamp without removing the entire lamp cover, the lamp cover When it is necessary to replace itself or to remove the entire lamp cover for some reason, the screw to which the hinge is attached must be removed using a tool such as a screwdriver, which is cumbersome. There is a problem.

本発明はこのような実情に鑑みてなされたもので、蛍光ランプの交換時には灯具カバー全体を取り外すことなく開閉可能で、しかも灯具カバーの全体を取り外す際にも全く工具を必要とすることのない鉄道車両用灯具の提供をその課題としている。   The present invention has been made in view of such circumstances, and can be opened and closed without removing the entire lamp cover when replacing the fluorescent lamp, and no tool is required when removing the entire lamp cover. The challenge is to provide railcar lamps.

上記の課題を解決するため、本発明の鉄道車両用灯具は、鉄道車両の客室内の天井部に取り付けられる灯具であって、蛍光ランプの両端部を支持して給電するための一対のランプソケットと、これらの各ランプソケットが接続される安定器を備えた灯具本体と、その灯具本体に支持されて上記蛍光ランプの下方を覆う灯具カバーを備えるとともに、その灯具カバーは、蛍光ランプに沿った一方の側縁側がラッチ機構を介して上記灯具本体に着脱自在に支持され、他方の側縁側は、灯具カバー側に固定されたバネが灯具本体側に固定された軸に係合することにより当該軸に対して回動自在に、かつ、着脱自在に支持され、上記バネは板バネからなり、その断面形状が、上記軸を抱き込むＣ字形部と、そのＣ字形部の開口部両端からそれぞれ当該Ｃ字形部の外側に突出して対向する対向部とからなり、その対向部は、上記Ｃ字形部の開口部から先端側に向けて互いに接近した後に離隔し、先端における対向寸法が上記軸の直径よりも大きくなっていることによって特徴づけられる。   In order to solve the above-described problems, a railcar lamp according to the present invention is a lamp that is attached to a ceiling portion in a passenger compartment of a railcar, and is a pair of lamp sockets for supporting and supplying power to both ends of a fluorescent lamp. And a lamp body provided with a ballast to which each of these lamp sockets is connected, and a lamp cover that is supported by the lamp body and covers the lower side of the fluorescent lamp. The lamp cover extends along the fluorescent lamp. One side edge side is detachably supported by the lamp body through a latch mechanism, and the other side edge side is supported by a spring fixed to the lamp cover side engaging with a shaft fixed to the lamp body side. The spring is made of a leaf spring, and is rotatably supported with respect to the shaft. The cross-sectional shape of the spring is a C-shaped portion that embraces the shaft, and both ends of the opening of the C-shaped portion. Concerned The opposing part protrudes to the outside of the character-shaped part, and the opposing part is separated after approaching from the opening of the C-shaped part toward the tip side, and the opposing dimension at the tip is larger than the diameter of the shaft Is also characterized by its growing size.

本発明は、ヒンジ機能と係合機能を併せ持ったバネおよび軸からなる機構をそれぞれ灯具カバーおよび灯具本体に設けることによって、灯具本体に対する灯具カバーの回動と着脱の双方を可能とし、課題を解決しようとするものである。   The present invention provides a mechanism comprising a spring and a shaft having both a hinge function and an engaging function in the lamp cover and the lamp body, respectively, thereby enabling both the rotation and attachment / detachment of the lamp cover with respect to the lamp body. It is something to try.

すなわち、灯具本体側に軸を設ける一方、灯具カバー側には、断面形状がＣ字形部とその開口部両端から外側に突出する対向する対向部を備えたバネを設け、そのバネの対向部を、Ｃ形部から先端側に向けて一旦接近した後に離隔させてその先端が軸の直径よりも大きく開口したものとすることにより、Ｃ字形部が軸に被嵌されている状態では、Ｃ字形部が軸の回りに回動するとともに、軸が対向部の間を通り抜ける向きにバネを移動させると、バネの弾性力に抗して対向部が開き、軸からバネを取り外すことができる。このような機構を介して灯具カバーの一方の側縁部を灯具本体に係合させ、他方の側縁部をラッチ機構を介して灯具本体に係合させると、蛍光ランプの交換時等においては、ラッチ機構を外して軸の回りに灯具カバーを回動させて開き、灯具カバーの交換時のように灯具カバー全体を取り外す必要のある場合には、同じくラッチ機構を外した後、灯具カバーを軸から引き抜くように移動させるだけで、工具を用いることなく灯具カバー全体を灯具本体から取り外すことができる。   That is, while the shaft is provided on the lamp body side, the lamp cover side is provided with a spring having a C-shaped section and opposing facing portions projecting outward from both ends of the opening. In the state where the C-shaped part is fitted on the shaft, the C-shaped part is once approached from the C-shaped part toward the distal end side and then separated from the C-shaped part so that the distal end is opened larger than the diameter of the shaft. When the portion rotates around the shaft and the spring is moved in a direction in which the shaft passes between the facing portions, the facing portion opens against the elastic force of the spring, and the spring can be removed from the shaft. When one side edge of the lamp cover is engaged with the lamp body via such a mechanism and the other side edge is engaged with the lamp body via the latch mechanism, when replacing the fluorescent lamp, etc. Remove the latch mechanism, rotate the lamp cover around the axis and open it. The entire lamp cover can be removed from the lamp body without using a tool by simply moving it so as to be pulled out of the shaft.

本発明によれば、灯具カバー全体を取り外すことなく当該灯具カバーを開くことが可能で、しかも灯具カバーの全体を取り外す必要のある場合には、工具を用いることなく簡単に取り外すことができ、蛍光ランプの交換作業および灯具カバー自体の交換作業の双方を容易に行うことができる。   According to the present invention, it is possible to open the lamp cover without removing the entire lamp cover, and when it is necessary to remove the entire lamp cover, the lamp cover can be easily removed without using a tool. Both lamp replacement work and lamp cover cover replacement work can be easily performed.

以下、図面を参照しつつ本発明の実施の形態について説明する。
図１は本発明の実施の形態を鉄道車両の天井部に取り付けた状態を示す断面図であり、図２はその疑似ヒンジ部１４の近傍の拡大図である。また、図３には図２のＡ−Ａ拡大断面図を示し、図４（Ａ），（Ｂ）には図３のＢ−Ｂ，Ｃ−Ｃ断面図を示す。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view showing a state where an embodiment of the present invention is attached to a ceiling portion of a railway vehicle, and FIG. 2 is an enlarged view of the vicinity of the pseudo hinge portion 14. 3 shows an AA enlarged sectional view of FIG. 2, and FIGS. 4A and 4B show sectional views of BB and CC of FIG.

この例において、本発明に係る灯具１は、車両天井部の空調ダクト２の下側に取り付けられている。なお、図１において３は横流ファン、４は冷風吹き出しグリル、５は吊手棒受けである。   In this example, the lamp 1 according to the present invention is attached to the lower side of the air conditioning duct 2 in the vehicle ceiling. In FIG. 1, 3 is a cross-flow fan, 4 is a cold-air blowing grille, and 5 is a suspension bar holder.

灯具１は灯具本体１１と、その灯具本体１１に対して後述するように回動自在かつ着脱自在に装着される灯具カバー１２を主体としている。灯具本体１１は、安定器（図示略）を収容する筐体１１ａに蛍光ランプ１３の両端部を支持する一対のランプソケット１１ｂを固定した構造を有している。そして、筐体１１ａには、灯具カバー１２の一方の側縁部を回動自在かつ着脱自在に支持する疑似ヒンジ部１４の灯具本体１１側の構成要素である軸１４１が固定されている。また、蛍光ランプ１３を挟んで疑似ヒンジ部１４と反対側には、灯具カバー１２の他方の側縁部を着脱自在に支持するラッチ機構１５の灯具本体１１側の構成要素である突片１５ａが設けられている。   The lamp 1 mainly includes a lamp main body 11 and a lamp cover 12 that is rotatably and detachably attached to the lamp main body 11 as will be described later. The lamp body 11 has a structure in which a pair of lamp sockets 11b that support both ends of the fluorescent lamp 13 are fixed to a housing 11a that houses a ballast (not shown). And the axis | shaft 141 which is the component by the side of the lamp main body 11 of the pseudo | simulation hinge part 14 which supports one side edge part of the lamp cover 12 so that rotation and attachment is possible is fixed to the housing | casing 11a. Further, on the side opposite to the pseudo hinge portion 14 with the fluorescent lamp 13 interposed therebetween, a projecting piece 15a that is a component on the lamp body 11 side of the latch mechanism 15 that detachably supports the other side edge portion of the lamp cover 12 is provided. Is provided.

灯具カバー１２は、フレーム１２ａに、蛍光ランプに直交する複数のフィン状の板材１２ｂを所定の間隔を開けて配置した構造を有し、フレーム１２ａの一方の側縁部に疑似ヒンジ部１４の灯具カバー１２側の構成要素であるバネ１４２が固着されている。また、フレーム１２ａの他方の側縁部には、ラッチ機構１５の灯具カバー１２側の構成要素である突部１５ｂが形成されている。   The lamp cover 12 has a structure in which a plurality of fin-shaped plate members 12b orthogonal to the fluorescent lamp are arranged at predetermined intervals on a frame 12a, and the lamp of the pseudo hinge part 14 is provided on one side edge of the frame 12a. A spring 142 as a component on the cover 12 side is fixed. Further, a protrusion 15b, which is a component on the lamp cover 12 side of the latch mechanism 15, is formed on the other side edge of the frame 12a.

さて、疑似ヒンジ部１４の軸１４１は、ブラケット１４１ａを介して灯具本体１１に固定されている。また、疑似ヒンジ部１４のバネ１４２は、板バネを屈曲させたものであって、その板厚に直交する断面形状が、図４（Ａ）に示すように、軸１４１を抱き込む形状・寸法の断面Ｃ字形部１４２ａと、その断面Ｃ字形部１４２ａの開口部両端から外側に突出して互いに対向する対向部１４２ｂを有し、対向部１４２ｂは、Ｃ字形部１４２ａの開口部から先端に向けて一旦接近した後に離隔し、最先端部での対向寸法は軸１４１の直径よりも大きくなっている。また、このバネ１４２の対向部１４２ｂの軸方向中央部分は、図３に示すように、軸１４１を支持するブラケット１４１ａとの干渉を避けるために切り欠かれている。   Now, the shaft 141 of the pseudo hinge portion 14 is fixed to the lamp body 11 via the bracket 141a. In addition, the spring 142 of the pseudo-hinge portion 14 is obtained by bending a leaf spring, and the cross-sectional shape perpendicular to the plate thickness is a shape / dimension for embedding the shaft 141 as shown in FIG. The cross-sectional C-shaped portion 142a and the opposing portion 142b projecting outward from both ends of the opening of the cross-sectional C-shaped portion 142a and facing each other, and the opposing portion 142b is directed from the opening of the C-shaped portion 142a toward the tip. Once approached, they are separated and the opposite dimension at the most distal part is larger than the diameter of the shaft 141. Further, the axially central portion of the facing portion 142b of the spring 142 is cut out in order to avoid interference with the bracket 141a that supports the shaft 141, as shown in FIG.

そして、このバネ１４２は、灯具カバー１２のフレーム１２ａに設けられた一対のリブ１２ｃに、その両端部が固定されている。すなわち、図２に示すように、各リブ１２ｃに半円状の孔１２ｄを形成するとともに、バネ１４２の両端部を、この半円形の孔１２ｄに嵌まり込む部分を残して他を切除し、その部分を半円形の孔に嵌め込んで固定している（図３参照）。   Then, both ends of the spring 142 are fixed to a pair of ribs 12 c provided on the frame 12 a of the lamp cover 12. That is, as shown in FIG. 2, each rib 12c is formed with a semicircular hole 12d, and both ends of the spring 142 are cut out while leaving the portions fitted into the semicircular hole 12d. The portion is fitted and fixed in a semicircular hole (see FIG. 3).

また、フレーム１２ａは、疑似ヒンジ機構１４の周囲で断面略Ｕ字形に屈曲しているのであるが、このフレーム１２ａには、後述する灯具カバー１２の取り外し時に軸１４１が通過できるように切欠き部１２ｅが形成されている。   Further, the frame 12a is bent in a substantially U-shaped cross section around the pseudo hinge mechanism 14, but the frame 12a has a notch portion so that the shaft 141 can pass when the lamp cover 12 described later is removed. 12e is formed.

以上の構成において、上記した各図に示すように灯具カバー１２が灯具本体１１に取り付けられている状態において、ラッチ機構１５の突部１５ｂを突片１５ａから外すことにより、灯具カバー１２は疑似ヒンジ機構１４によってのみ灯具本体１１に対して支持されている状態となり、この状態では、バネ１４２が軸１４１を抱き込んだ状態となっているので、灯具カバー１２はバネ１４２を介して軸１４１の回りに回動自在となり、灯具カバー１２を取り外すことなく蛍光ランプ１３の交換等が可能である。この状態では、バネ１４２の対向部１４２ｂがＣ字形部１４２ａから外側で一旦接近しているので、バネ１４２ｂが、従って灯具カバー１２が軸１４１から外れることなく当該軸１４１の回りを揺動する。   In the above configuration, when the lamp cover 12 is attached to the lamp body 11 as shown in each of the above-described drawings, the lamp cover 12 is made to be a pseudo hinge by removing the protrusion 15b of the latch mechanism 15 from the protrusion 15a. Only the mechanism 14 is in a state of being supported with respect to the lamp body 11. In this state, the spring 142 is in a state of holding the shaft 141, so the lamp cover 12 is rotated around the shaft 141 via the spring 142. The fluorescent lamp 13 can be replaced without removing the lamp cover 12. In this state, since the facing portion 142b of the spring 142 is once approaching from the C-shaped portion 142a, the spring 142b swings around the shaft 141 without the lamp cover 12 being detached from the shaft 141.

また、灯具カバー１２自体を交換する場合等において、この灯具カバー１２を取り外すには、図５に示すように、灯具カバー１２を軸１４１の回りに回動させて略鉛直に沿った姿勢にし、その状態から、図６に示すように、図示する矢印のように右下に灯具カバー１２を引くことにより、バネ１４２のＣ字形部１４２ａが軸１４１から外れ、対向部１４２ｂの間を通じて軸１４１に対してバネ１４２を引き抜くことができる。このとき、フレーム１２ａに形成している切欠き部１２ｅにより軸１４１とフレーム１２ａとが干渉することなく、灯具カバー１２を灯具本体１１から完全に取り外すことができる。   In order to remove the lamp cover 12 when the lamp cover 12 is replaced, as shown in FIG. From this state, as shown in FIG. 6, by pulling the lamp cover 12 to the lower right as shown in the figure, the C-shaped portion 142a of the spring 142 is detached from the shaft 141, and the shaft 141 passes through the space between the opposing portions 142b. On the other hand, the spring 142 can be pulled out. At this time, the lamp cover 12 can be completely removed from the lamp body 11 without the shaft 141 and the frame 12a interfering with each other by the notch 12e formed in the frame 12a.

灯具カバー１２を灯具本体１１に装着する場合には、図６の矢印と反対に、バネ１４２をその対向部１４２ｂを通じて軸１４１に嵌め込んでいき、軸１４１がＣ字形部１４２ａに抱き込まれるようにすればよい。このとき、対向部１４２ｂの先端の対向寸法が軸１４１の直径よりも大きくなっているため、装着作業は容易である。また、対向部１４２ｂはＣ字形部１４２ａに至るまでに一旦接近しているため、この接近部分を軸１４１が通過した後は、バネ１４２の弾性力により軸１４１がＣ字形部１４２ａ内に簡単に収まる。   When the lamp cover 12 is attached to the lamp body 11, the spring 142 is fitted into the shaft 141 through the opposed portion 142b, opposite to the arrow in FIG. 6, so that the shaft 141 is held in the C-shaped portion 142a. You can do it. At this time, since the facing dimension of the tip of the facing portion 142b is larger than the diameter of the shaft 141, the mounting operation is easy. Further, since the facing portion 142b is once approached until reaching the C-shaped portion 142a, after the shaft 141 passes through this approaching portion, the shaft 141 is easily put into the C-shaped portion 142a by the elastic force of the spring 142. It will fit.

従って以上の本発明の実施の形態によれば、蛍光ランプ１３の交換時等においては、ラッチ機構１５を外して灯具カバー１２を回動させることにより当該灯具カバー１２を開くことができ、しかも、灯具カバー１２の交換時等においては、ドライバをはじめとする工具を一切使用することなく、灯具本体１１に対して灯具カバー１２を取り外し、あるいは取り付けることができる。   Therefore, according to the above-described embodiment of the present invention, when replacing the fluorescent lamp 13, the lamp cover 12 can be opened by removing the latch mechanism 15 and rotating the lamp cover 12, and When the lamp cover 12 is replaced, the lamp cover 12 can be removed from or attached to the lamp body 11 without using any tool such as a screwdriver.
