Description

本発明は、例えば鉄道等のドアの開閉表示灯として使用される表示標識灯に関する。 The present invention relates to an indicator lamp used as an open / close indicator lamp for a door of a railway or the like, for example.

近年、鉄道等の車両には、ドア近傍にドアの開閉予告等を行う開閉表示灯が取り付けられている。これにより、乗客や車掌にドアの開閉を知らせ、乗客の円滑な乗り降りを誘導することを可能としている。近年では、このような開閉表示灯として発光ダイオード（ＬＥＤ）を使用したものが普及しつつある（例えば、特許文献１）。 In recent years, vehicles such as railroads are equipped with an open / close indicator light near the door to give notice of opening / closing of the door. This makes it possible to notify passengers and conductors of the opening and closing of doors and guide passengers to get on and off smoothly. In recent years, those using a light emitting diode (LED) as such an open / close indicator lamp have become widespread (for example, Patent Document 1).

登録実用新案第３０４７４４８号公報Registered Utility Model No. 3047448

開閉表示灯を車両の内面に取り付ける方法としては、車体に長角穴を開け、取付け用のネジ座等を用いて固定する方法が知られている。しかしながら、このような方法では作業が大掛かりとなり、車体に対する加工負荷が大きくなる課題がある。 As a method of mounting the open / close indicator light on the inner surface of the vehicle, a method of making an elongated hole in the vehicle body and fixing it by using a screw seat for mounting or the like is known. However, such a method has a problem that the work becomes large and the processing load on the vehicle body becomes large.

以上のような事情に鑑み、本発明の目的は、車両の内面に取り付ける際に作業が大掛かりにならず、車体に対する加工負荷を軽減可能な表示標識灯を提供することにある。 In view of the above circumstances, an object of the present invention is to provide a display indicator lamp that does not require a large amount of work when mounted on the inner surface of a vehicle and can reduce the processing load on the vehicle body.

上記目的を達成するため、本発明の一形態に係る表示標識灯は、光出射部材と、光源と、保持部材と、を有する。
上記光出射部材は、光出射部と、柱状の導光部と、を有する。
上記光出射部は、支持体の第１の主面に取り付け可能に構成される。
上記導光部は、上記光出射部に接続された第１の端部と、上記第１の端部とは反対側の第２の端部と、を有し、上記支持体を貫通する。
上記光源は、前記第２の端部に対向する。
上記保持部材は、上記第１の主面とは反対側の第２の主面に取り付け可能に構成された本体部と、上記本体部に設けられ上記第２の端部に係止する第１の係止部と、上記光源を保持する保持部と、を有する。 In order to achieve the above object, the display indicator lamp according to one embodiment of the present invention includes a light emitting member, a light source, and a holding member.
The light emitting member has a light emitting portion and a columnar light guide portion.
The light emitting portion is configured to be attachable to the first main surface of the support.
The light guide portion has a first end portion connected to the light emitting portion and a second end portion opposite to the first end portion, and penetrates the support.
The light source faces the second end.
The holding member has a main body portion configured to be mountable on a second main surface opposite to the first main surface, and a first main body portion provided on the main body portion and locked to the second end portion. It has a locking portion and a holding portion for holding the light source.

この構成によれば、支持体に形成された取付け孔を介して保持部材が光出射部材を保持し、当該保持部材が光源も保持する。 According to this configuration, the holding member holds the light emitting member through the mounting hole formed in the support, and the holding member also holds the light source.

つまり、上記表示標識灯の光出射部材及び光源は、車両に取付け孔を形成する簡単な施工だけで車両に取り付けられる。換言すると、本発明では、表示標識灯を車両に取り付ける上で必要とされる施工が、車両に取付け孔を形成する加工に限定される。 That is, the light emitting member and the light source of the indicator lamp can be attached to the vehicle only by a simple construction for forming a mounting hole in the vehicle. In other words, in the present invention, the construction required for mounting the indicator light on the vehicle is limited to the processing for forming the mounting hole in the vehicle.

従って、本発明により、車両に取り付ける際に作業が大掛かりにならず、車体に対する加工負荷を軽減可能な表示標識灯を提供することができる。 Therefore, according to the present invention, it is possible to provide an indicator lamp that does not require a large amount of work when attached to a vehicle and can reduce the processing load on the vehicle body.

上記第２の端部は、上記導光部の短手方向に突出する凸部を有し、
上記第１の係止部は、上記凸部に係止可能に構成された第１の突起部を有してもよい。
これにより、凸部が第１の突起部に係止することで、光出射部材が保持部材に保持される。 The second end portion has a convex portion protruding in the lateral direction of the light guide portion.
The first locking portion may have a first protruding portion configured to be lockable on the convex portion.
As a result, the convex portion is locked to the first protrusion, so that the light emitting member is held by the holding member.

上記光源は、回路基板と、上記回路基板上に設けられた発光素子とを有し、
上記保持部は、上記回路基板を貫通し、上記回路基板に係止可能に構成された第２の係止部を有してもよい。
これにより、回路基板が第２の係止部に係止することで、光源が保持部材に保持される。 The light source has a circuit board and a light emitting element provided on the circuit board.
The holding portion may have a second locking portion that penetrates the circuit board and is configured to be lockable to the circuit board.
As a result, the circuit board is locked to the second locking portion, so that the light source is held by the holding member.

上記回路基板は、上記第２の係止部に挿通される貫通孔を有し、
上記第２の係止部は、上記貫通孔の径外方へ突出し、上記回路基板に係止する第２の突起部を有してもよい。
これにより、光源の導光部から離間する方向への移動が阻止され、光源をより強固に位置決めすることが可能となる。 The circuit board has a through hole to be inserted through the second locking portion.
The second locking portion may have a second protruding portion that protrudes outward from the diameter of the through hole and locks to the circuit board.
As a result, the movement of the light source in the direction away from the light guide portion is prevented, and the light source can be positioned more firmly.

上記光源は、複数の発光素子を有し、
上記光出射部材は、上記複数の発光素子各々に対向する複数の導光部を有し、
上記保持部材は、上記複数の導光部各々に係止する複数の第１の係止部を有してもよい。
これにより、装置構成を複雑にせずに、所望とする光度を確保することが可能となる。 The light source has a plurality of light emitting elements and has a plurality of light emitting elements.
The light emitting member has a plurality of light guide portions facing each of the plurality of light emitting elements.
The holding member may have a plurality of first locking portions that are locked to each of the plurality of light guide portions.
This makes it possible to secure the desired luminous intensity without complicating the device configuration.

上記光出射部と上記保持部材との間に設けられたスペーサをさらに具備してもよい。
これにより、支持体の厚みや導光部の長手方向の寸法に依存せずに、支持体に対して光出射部材と保持部材とを位置決めすることが可能となる。 A spacer provided between the light emitting portion and the holding member may be further provided.
This makes it possible to position the light emitting member and the holding member with respect to the support without depending on the thickness of the support and the lengthwise dimension of the light guide portion.

上記保持部材は、カバー部をさらに有してもよい。上記カバー部は、上記本体部に接続され、上記第２の主面側から上記光源及び上記本体部を覆う。
これにより、回路基板に異物等が混入、付着することが抑制され、回路基板が剥き出しなることに伴う不具合が解消される。 The holding member may further have a cover portion. The cover portion is connected to the main body portion and covers the light source and the main body portion from the second main surface side.
As a result, foreign matter and the like are suppressed from being mixed and adhered to the circuit board, and the problems associated with the bare circuit board are eliminated.

以上のように、本発明によれば、車両の内面に取り付ける際に作業が大掛かりにならず、車体に対する加工負荷を軽減可能な表示標識灯を提供することができる。 As described above, according to the present invention, it is possible to provide a display indicator lamp that does not require a large amount of work when mounted on the inner surface of the vehicle and can reduce the processing load on the vehicle body.

In the following figure, the X-axis, Y-axis, and Z-axis directions are three-axis directions orthogonal to each other.

＜表示標識灯の構成＞
表示標識灯１００は、図１に示すように、例えば鉄道等の車両のドア近傍に設置される開閉表示灯（開閉予告灯）である。表示標識灯１００は、図２及び図３に示すように、光出射部材１１０と、光源１２０と、保持部材１３０と、を有する。 <Structure of display indicator light>
As shown in FIG. 1, the display indicator light 100 is an open / close indicator light (open / close warning light) installed near the door of a vehicle such as a railway. As shown in FIGS. 2 and 3, the display indicator lamp 100 includes a light emitting member 110, a light source 120, and a holding member 130.

［光出射部材］
光出射部材１１０は、光出射部１１１と導光部１１２とを有する。 [Light emitting member]
The light emitting member 110 has a light emitting unit 111 and a light guide unit 112.

（光出射部）
光出射部１１１は板状形状を有し、支持体Ｓの第１主面Ｓ１に対向する。光出射部１１１は、支持体Ｓに取り付け可能に構成される。 (Light emitting part)
The light emitting portion 111 has a plate-like shape and faces the first main surface S1 of the support S. The light emitting unit 111 is configured to be attachable to the support S.

ここで、本実施形態の支持体Ｓとは、図１に示すように、例えばドアエンジン等が収容されている筐体Ｂの一部であり、開閉ドア２の鉛直上方に設けられたキセ板である。 Here, as shown in FIG. 1, the support S of the present embodiment is a part of the housing B in which, for example, a door engine or the like is housed, and is a skein plate provided vertically above the opening / closing door 2. Is.

支持体Ｓには図２及び図３に示すように、第１主面Ｓ１と、第１主面Ｓ１とは反対側の第２主面Ｓ２とを連通させる取付け孔Ｈ１が、Ｙ軸方向に所定の間隔を空けて複数形成されている。取付け孔Ｈ１の形状や数は、特に限定されず、導光部１１２の形状や数に対応して適宜決定可能である。 As shown in FIGS. 2 and 3, the support S has a mounting hole H1 for communicating the first main surface S1 and the second main surface S2 on the opposite side of the first main surface S1 in the Y-axis direction. A plurality of them are formed at predetermined intervals. The shape and number of the mounting holes H1 are not particularly limited, and can be appropriately determined according to the shape and number of the light guide unit 112.

光出射部１１１は、第１主面Ｓ１に対向する対向面１１１ａとその反対側の光出射面１１１ｂとを有する。対向面１１１ａは第１主面Ｓ１に当接する平坦な面である（図１０参照）。 The light emitting unit 111 has a facing surface 111a facing the first main surface S1 and a light emitting surface 111b on the opposite side thereof. The facing surface 111a is a flat surface that abuts on the first main surface S1 (see FIG. 10).

図４は、光出射部１１１をＺ軸方向から見た平面図である。本実施形態において光出射部１１１の周縁部は、対向面１１１ａ側から光出射面１１１ｂに向かって、光出射部１１１のＹ軸方向の寸法Ｄ１を漸少させ、Ｙ軸方向に互いに対向するテーパー面Ｔ１を有する。また、光出射部１１１のＸ軸方向の寸法Ｄ２を漸少させ、Ｘ軸方向に互いに対向するテーパー面Ｔ２を有する。 FIG. 4 is a plan view of the light emitting unit 111 as viewed from the Z-axis direction. In the present embodiment, the peripheral edge portion of the light emitting portion 111 gradually reduces the dimension D1 of the light emitting portion 111 in the Y-axis direction from the facing surface 111a side toward the light emitting surface 111b, and is tapered so as to face each other in the Y-axis direction. It has a surface T1. Further, the dimension D2 in the X-axis direction of the light emitting unit 111 is gradually reduced to have tapered surfaces T2 facing each other in the X-axis direction.

光出射面１１１ｂは、導光部１１２を介して伝送された光を外部へ照射する。光出射面１１ｂには図２に示すように、拡散部１１１ｃが設けられてもよい。これにより、光出射部１１１は、導光部１１２を介して入射した光源１２０（発光素子１２２）由来の照明光を、光出射面１１１ｂの面内において拡散させることが可能となる。 The light emitting surface 111b irradiates the light transmitted through the light guide unit 112 to the outside. As shown in FIG. 2, the light emitting surface 11b may be provided with a diffuser portion 111c. As a result, the light emitting unit 111 can diffuse the illumination light derived from the light source 120 (light emitting element 122) incident through the light guide unit 112 in the surface of the light emitting surface 111b.

拡散部１１１ｃは、例えばプリズム状に加工することにより形成された複数の凸部から構成される。なお、拡散部１１１ｃの加工形状はプリズム状に限定されず、球状又は格子状等その種類は問わない。また、拡散部１１１ｃはプリズム加工が施されたプリズムシート等であってもよい。 The diffusion portion 111c is composed of a plurality of convex portions formed by, for example, processing into a prism shape. The processed shape of the diffusion portion 111c is not limited to the prism shape, and the type thereof such as a spherical shape or a grid shape does not matter. Further, the diffusion portion 111c may be a prism sheet or the like that has been subjected to prism processing.

光出射部１１１の形状は典型的には矩形状であり、Ｘ軸方向の寸法Ｄ１が約７０ｍｍ、Ｙ軸方向の寸法Ｄ２が約２０ｍｍである。また、Ｚ軸方向の厚みＤ３は、約５ｍｍである。なお、光出射部１１１の形状は矩形状に限定されず、例えば三角や円形、あるいは楕円形状等その種類は問わない。 The shape of the light emitting portion 111 is typically rectangular, with the dimension D1 in the X-axis direction being about 70 mm and the dimension D2 in the Y-axis direction being about 20 mm. Further, the thickness D3 in the Z-axis direction is about 5 mm. The shape of the light emitting portion 111 is not limited to a rectangular shape, and any type such as a triangular shape, a circular shape, or an elliptical shape may be used.

光出射部１１１の材料としては、透明性あるいは透光性を有する材料、典型的にはメタクリル樹脂（ＰＭＭＡ）が採用されるが、これに限られず、例えば、トリアセチルセルロース（ＴＡＣ）、ポリエステル（ＴＰＥＥ）、ポリエチレンテレフタレート（ＰＥＴ）、ポリイミド（ＰＩ）、ポリアミド（ＰＡ）、アラミド、ポリエチレン（ＰＥ）、ポリアクリレート、ポリエーテルスルフォン、ポリスルフォン、ポリプロピレン（ＰＰ）、ジアセチルセルロース、ポリ塩化ビニル、ポリカーボネート（ＰＣ）、エポキシ樹脂、尿素樹脂、ウレタン樹脂、メラミン樹脂又はガラス材料等が採用されてもよい。 As the material of the light emitting portion 111, a transparent or translucent material, typically a methacrylic resin (PMMA) is adopted, but the material is not limited to this, and for example, triacetyl cellulose (TAC) and polyester ( TPEE), Polyethylene terephthalate (PET), Polyethylene (PI), Polyester (PA), Aramid, Polyethylene (PE), Polyacrylate, Polyether sulphon, Polysulphon, Polyester (PP), Diacetyl cellulose, Polyvinyl chloride, Polycarbonate (TPEE) PC), epoxy resin, urea resin, urethane resin, melamine resin, glass material and the like may be adopted.

（導光部）
導光部１１２は円柱状に構成され、第１端部１１２ａと第２端部１１２ｂとを有する。第１端部１１２ａは、光出射部１１１の対向面１１１ａに接続されている。第２端部１１２ｂはＺ軸方向（光源１２０が照明光を出射する方向）に光源１２０（発光素子１２２）に対向する。第２端部１１２ｂは、光源１２０からの出射光が入射する光入射部として機能する。 (Light guide section)
The light guide portion 112 is formed in a columnar shape and has a first end portion 112a and a second end portion 112b. The first end portion 112a is connected to the facing surface 111a of the light emitting portion 111. The second end portion 112b faces the light source 120 (light emitting element 122) in the Z-axis direction (direction in which the light source 120 emits illumination light). The second end portion 112b functions as a light incident portion to which the light emitted from the light source 120 is incident.

本実施形態では、第１端部１１２ａは光源１２０（発光素子１２２）と接触していてもよい。この場合、第１端部１１２ａは、例えば光透過性のある接着剤を介して光源１２０（発光素子１２２）に接合される。これにより、第１端部１１２ａと光源１２０との間に空気層が介在することを回避できるので、第１端部１１２ａから導光部１１２内部への光源光の入射効率が高められる。 In the present embodiment, the first end portion 112a may be in contact with the light source 120 (light emitting element 122). In this case, the first end portion 112a is joined to the light source 120 (light emitting element 122) via, for example, a light-transmitting adhesive. As a result, it is possible to prevent the air layer from interposing between the first end portion 112a and the light source 120, so that the incident efficiency of the light source light from the first end portion 112a to the inside of the light source portion 112 is enhanced.

また、導光部１１２は、光出射部１１１と一体的又は別体的に形成されてもよいが、生産性の観点から一体的に形成されていることが好ましい。光出射部１１１及び導光部１１２は、典型的には同一の透明プラスチック材料で一体成形された成形部品で構成される。 Further, the light guide unit 112 may be formed integrally or separately from the light emitting unit 111, but it is preferable that the light guide unit 112 is integrally formed from the viewpoint of productivity. The light emitting unit 111 and the light guide unit 112 are typically composed of molded parts integrally molded from the same transparent plastic material.

さらに、導光部１１２は図３に示すように、Ｙ軸方向に所定の間隔を空けて光出射部１１１に複数設けられる。ここで、導光部１１２は、取付け孔Ｈ１と光源１２０（発光素子１２２）とＺ軸方向に対向するように対向面１１１ａに設けられる。なお、導光部１１２の数は、発光素子１２２の数に応じて適宜決定され、本実施形態では２本である。 Further, as shown in FIG. 3, a plurality of light guide units 112 are provided in the light emitting unit 111 at predetermined intervals in the Y-axis direction. Here, the light guide unit 112 is provided on the facing surface 111a so as to face the mounting hole H1 and the light source 120 (light emitting element 122) in the Z-axis direction. The number of light guide units 112 is appropriately determined according to the number of light emitting elements 122, and is two in this embodiment.

本実施形態の導光部１１２は、光源１２０（発光素子１２２）が光出射部１１１側に出射した照明光を、内部で全反射させながら光出射部１１１へ誘導する機能を有する。これにより、光出射部１１１に向けて必要光度の照明光を効率良く導くことができ、光源１２０の光の利用効率を向上させることが可能となる。 The light guide unit 112 of the present embodiment has a function of guiding the illumination light emitted by the light source 120 (light emitting element 122) to the light emitting unit 111 side to the light emitting unit 111 while totally reflecting the illumination light inside. As a result, it is possible to efficiently guide the illumination light having the required luminous intensity toward the light emitting unit 111, and it is possible to improve the utilization efficiency of the light of the light source 120.

図５は、導光部１１２の拡大図である。導光部１１２は図５に示すように、凸部１１２ｃが一体的に形成されている。凸部１１２ｃは、導光部１１２の第２端部１１２ｂにおける周面に連続的に形成され、当該周面から導光部１１２の径外方へ突出している。 FIG. 5 is an enlarged view of the light guide unit 112. As shown in FIG. 5, the light guide portion 112 is integrally formed with a convex portion 112c. The convex portion 112c is continuously formed on the peripheral surface of the second end portion 112b of the light guide portion 112, and protrudes outward from the peripheral surface of the light guide portion 112.

凸部１１２ｃは、導光部１１２のＺ軸方向上端から対向面１１１ａに向かって直径を漸増させるテーパー面Ｆ１と、テーパー面Ｆ１に接続され、Ｚ軸方向に平行な平面Ｆ３と、平面Ｆ３に接続され、導光部１１２の直径をＺ軸方向上端側から対向面１１１ａに向かって漸少させるテーパー面Ｆ２とを有する。 The convex portion 112c is connected to a tapered surface F1 that gradually increases in diameter from the upper end of the light guide portion 112 in the Z-axis direction toward the facing surface 111a, and a flat surface F3 parallel to the Z-axis direction and a flat surface F3. It has a tapered surface F2 which is connected and gradually reduces the diameter of the light guide portion 112 from the upper end side in the Z-axis direction toward the facing surface 111a.

図６は、導光部１１２の拡大図であり、凸部１１２ｃが採り得る他の形態を示す図である。本実施形態の凸部１１２ｃは、同図に示すように、曲面から構成されてもよい。 FIG. 6 is an enlarged view of the light guide portion 112, and is a diagram showing other forms that the convex portion 112c can take. As shown in the figure, the convex portion 112c of the present embodiment may be composed of a curved surface.

この場合、凸部１１２ｃはその断面形状において、導光部１１２の第２端部１１２ｂから外周面に向かって連続する曲面から構成される。この曲面は、曲率半径Ｒ１を有する円の一部を構成する円弧とすることができる。曲率半径Ｒ１は特に限定されず、例えば０．５ｍｍ程度である。 In this case, the convex portion 112c is composed of a curved surface continuous from the second end portion 112b of the light guide portion 112 toward the outer peripheral surface in its cross-sectional shape. This curved surface can be an arc forming a part of a circle having a radius of curvature R1. The radius of curvature R1 is not particularly limited, and is, for example, about 0.5 mm.

なお、上記曲面は、一定の曲率で構成される場合に限られず、曲率半径の異なる複数の円弧を含んでもよい。この場合、曲面の曲率半径Ｒ１は、例えば０．５～１．５ｍｍの範囲内に設定される。 The curved surface is not limited to the case where it is composed of a constant curvature, and may include a plurality of arcs having different radii of curvature. In this case, the radius of curvature R1 of the curved surface is set within the range of, for example, 0.5 to 1.5 mm.

導光部１１２の直径Ｄ４は７～８ｍｍ程度である。また、導光部１１２の凸部１１２ｃを含む最大径Ｄ５は、後述する第１係止部１３３の最小内径Ｄ１１（図９参照）より大きければ特に限定されず、本例では８～９ｍｍ程度である。 The diameter D4 of the light guide unit 112 is about 7 to 8 mm. Further, the maximum diameter D5 including the convex portion 112c of the light guide portion 112 is not particularly limited as long as it is larger than the minimum inner diameter D11 (see FIG. 9) of the first locking portion 133 described later, and in this example, it is about 8 to 9 mm. be.

導光部１１２は、典型的にはアクリル樹脂（ＰＭＭＡ）から構成されるが、これに限られず、上記で列挙した材料から構成されてもよい。また、導光部１１２は光出射部１１１と同一の材料から構成されてもよく、異なる材料から構成されてもよい。 The light guide unit 112 is typically made of acrylic resin (PMMA), but is not limited to this, and may be made of the materials listed above. Further, the light guide unit 112 may be made of the same material as the light emitting unit 111, or may be made of a different material.

導光部１１２は、典型的には円柱形状であるが、これに限られず、例えば三角柱や矩形柱等その種類は問わない。 The light guide unit 112 is typically in the shape of a cylinder, but is not limited to this, and the type thereof is not limited, for example, a triangular prism or a rectangular prism.

（回路基板）
回路基板１２１はＹ軸方向の両端において、表裏面を連通させる複数の貫通孔Ｈ２を有する。貫通孔Ｈ２の数は、後述する保持部１３４の数に応じて適宜決定され、本実施形態では２つである。また。回路基板１２１は、主面Ｓ４に設けられたコネクタＣを介して配線Ｌに接続される（図１０参照）。 (Circuit board)
The circuit board 121 has a plurality of through holes H2 that allow the front and back surfaces to communicate with each other at both ends in the Y-axis direction. The number of through holes H2 is appropriately determined according to the number of holding portions 134 described later, and is two in the present embodiment. Also. The circuit board 121 is connected to the wiring L via the connector C provided on the main surface S4 (see FIG. 10).

第１係止部１３３は、典型的には台座部１３１ａを構成する材料と同一の材料から構成されるが、これに限られず、異なる種類の材料から構成されてもよい。 The first locking portion 133 is typically made of the same material as the material constituting the pedestal portion 131a, but is not limited to this, and may be made of a different kind of material.

保持部１３４は、回路基板１２１の貫通孔Ｈ２とＺ軸方向に対向する位置において複数設けられ、台座部１３１ａと一体的に形成される。保持部１３４の数は特に限定されず、貫通孔Ｈ２の数に応じて適宜決定可能であり、本実施形態では２つである。 A plurality of holding portions 134 are provided at positions facing the through holes H2 of the circuit board 121 in the Z-axis direction, and are integrally formed with the pedestal portion 131a.

本実施形態の第２係止部１３４ｂは、図８に示すように、第２突起部１３４ｃを有する。第２突起部１３４ｃは、第２係止部１３４ｂのＺ軸方向上端部近傍において、第２係止部１３４ｂを構成する板状部と一体的に形成されている。 The second locking portion 134b of the present embodiment has a second protrusion 134c as shown in FIG. The second protrusion 134c is formed integrally with the plate-shaped portion constituting the second locking portion 134b in the vicinity of the upper end portion in the Z-axis direction of the second locking portion 134b.

第２突起部１３４ｃは、貫通孔Ｈ２の径外方へ突出している。ここで、Ｙ軸方向における第２突起部１３４ｃ間の距離Ｄ１０（第２係止部１３４ｂのＹ軸方向の最大寸法）は、回路基板１２１の貫通孔Ｈ２の内径Ｈ６よりも大きい。 The second protrusion 134c projects outward from the diameter of the through hole H2. Here, the distance D10 between the second protrusions 134c in the Y-axis direction (the maximum dimension of the second locking portion 134b in the Y-axis direction) is larger than the inner diameter H6 of the through hole H2 of the circuit board 121.

第２係止部１３４ｂを構成する板状部の数は、図８に示す数に限定されず、適宜決定可能であり、２つ以上であってもよい。また、保持部１３４は、典型的には台座部１３１ａを構成する材料と同一の材料から構成されるが、これに限られず、異なる材料から構成されてもよい。 The number of plate-shaped portions constituting the second locking portion 134b is not limited to the number shown in FIG. 8, and can be appropriately determined, and may be two or more. Further, the holding portion 134 is typically made of the same material as the material constituting the pedestal portion 131a, but is not limited to this, and may be made of a different material.

（カバー部）
カバー部１３２は、光源１２０よりＺ軸方向上方に配置され、支持体Ｓの第２主面Ｓ２に対向する。カバー部１３２は、光源１２０側に向かって開口する収容空間１３２ｄを有する筐体として構成される。 (Cover part)
The cover portion 132 is arranged above the light source 120 in the Z-axis direction and faces the second main surface S2 of the support S. The cover portion 132 is configured as a housing having a storage space 132d that opens toward the light source 120 side.

カバー部１３２は、本体部１３１に形成された切欠き１３１ｂとＺ軸方向に対向する位置において、Ｙ軸方向側面に切欠き１３２ｂを有する。この切欠き１３２ｂは、図２に示すように、上記Ｙ軸方向側面の下端部から上端部に向かって形成されている。 The cover portion 132 has a notch 132b on the side surface in the Y-axis direction at a position facing the notch 131b formed in the main body portion 131 in the Z-axis direction. As shown in FIG. 2, the notch 132b is formed from the lower end portion of the side surface in the Y-axis direction toward the upper end portion.

本実施形態のカバー部１３２は、ヒンジＨを介して本体部１３１に接続されている。ここで、ヒンジＨの一端はカバー部１３２と一体的に接続され、他端が本体部１３１に挿入されている。カバー部１３２及びヒンジＨは、典型的には同一の材料で一体成形された成形部品で構成される。 The cover portion 132 of the present embodiment is connected to the main body portion 131 via the hinge H. Here, one end of the hinge H is integrally connected to the cover portion 132, and the other end is inserted into the main body portion 131. The cover portion 132 and the hinge H are typically composed of molded parts integrally molded from the same material.

カバー部１３２は、第２主面Ｓ２側から光源１２０及び本体部１３１を覆うことができる（図１０参照）。これにより、カバー部１３２は、収容空間１３２ａと、本体部１３１の収容空間１３１ｄとで光源１２０を収容する空間を区画することが可能となる。 The cover portion 132 can cover the light source 120 and the main body portion 131 from the second main surface S2 side (see FIG. 10). As a result, the cover portion 132 can partition the space for accommodating the light source 120 between the accommodating space 132a and the accommodating space 131d of the main body portion 131.

従って、回路基板１２１に異物等が混入、付着することが抑制され、回路基板１２１が剥き出しになることに伴う不具合が解消される。 Therefore, it is possible to prevent foreign matter and the like from being mixed and adhered to the circuit board 121, and the problems associated with the exposed circuit board 121 are eliminated.

カバー部１３２は典型的には、台座部１３１ａを構成する材料と同一の材料から構成されるが、これに限られず、異なる材料から構成されてもよい。 The cover portion 132 is typically made of the same material as the material constituting the pedestal portion 131a, but is not limited to this, and may be made of a different material.

＜取り付け方法＞
次に、表示標識灯１００を支持体Ｓに取り付ける方法について説明する。図１０は、表示標識灯１００の断面図であり、表示標識灯１００を支持体Ｓに取り付けた状態を示す図である。なお、表示標識灯１００を支持体Ｓに取り付ける方法は、以下で説明する方法に限定されるものではない。 <How to install>
Next, a method of attaching the indicator lamp 100 to the support S will be described. FIG. 10 is a cross-sectional view of the display indicator light 100, and is a diagram showing a state in which the display indicator light 100 is attached to the support S. The method of attaching the indicator lamp 100 to the support S is not limited to the method described below.

先ず、回路基板１２１の貫通孔Ｈ２に主面Ｓ３側から第２係止部１３４ｂを挿通させ、回路基板１２１を第２係止部１３４ｂに係止させる。 First, the second locking portion 134b is inserted into the through hole H2 of the circuit board 121 from the main surface S3 side, and the circuit board 121 is locked to the second locking portion 134b.

ここで、本実施形態の第２係止部１３４ｂは弾性変形可能に構成されている。これにより、第２係止部１３４ｂは、貫通孔Ｈ２の径内方に変形可能となる。従って、貫通孔Ｈ２に第２係止部１３４ｂを挿通させる際に、第２係止部１３４ｂに加えられる応力が貫通孔Ｈ２の径内方へ逃げやすくなる。 Here, the second locking portion 134b of the present embodiment is configured to be elastically deformable. As a result, the second locking portion 134b can be deformed inward in the diameter of the through hole H2. Therefore, when the second locking portion 134b is inserted through the through hole H2, the stress applied to the second locking portion 134b tends to escape inward in the diameter of the through hole H2.

特に、第２係止部１３４ｂはテーパー面Ｆ７を有するため、貫通孔Ｈ２の周縁がテーパー面Ｆ７に当接する。これにより、テーパー面Ｆ７が貫通孔Ｈ２に第２係止部１３４ｂを挿通する際の逃げ面として機能し、上記効果がより顕著となる。 In particular, since the second locking portion 134b has the tapered surface F7, the peripheral edge of the through hole H2 comes into contact with the tapered surface F7. As a result, the tapered surface F7 functions as a flank when the second locking portion 134b is inserted into the through hole H2, and the above effect becomes more remarkable.

即ち、本実施形態では、第２係止部１３４ｂが弾性変形可能であり、且つ、テーパー面Ｆ７を有することにより、貫通孔Ｈ２に第２係止部１３４ｂを挿通させやすくなる。ゆえに、表示標識灯１００の組立性が向上する。 That is, in the present embodiment, the second locking portion 134b is elastically deformable and has the tapered surface F7, so that the second locking portion 134b can be easily inserted into the through hole H2. Therefore, the assemblability of the indicator lamp 100 is improved.

また、第２係止部１３４ｂが回路基板１２１に係止している状態においては、第２突起部１３４ｃが回路基板１２１の主面Ｓ４に当接し、貫通孔Ｈ２の内周面が第２係止部１３４ｂを構成する板状部によりＹ軸方向に押圧される。 Further, in a state where the second locking portion 134b is locked to the circuit board 121, the second protrusion 134c abuts on the main surface S4 of the circuit board 121, and the inner peripheral surface of the through hole H2 is in second contact. It is pressed in the Y-axis direction by the plate-shaped portion constituting the stop portion 134b.

これにより、第２突起部１３４ｃが貫通孔Ｈ２の周縁に引っ掛かるだけではなく、第２係止部１３４ｂが貫通孔Ｈ２の内周面を径外方へ常に付勢するものとなる（図１２参照）。従って、光源１２０の導光部１１２から離間する方向への移動が阻止され、保持部１３４に光源１２０がより強固に位置決めされるものとなる。 As a result, not only the second protrusion 134c is caught on the peripheral edge of the through hole H2, but also the second locking portion 134b always urges the inner peripheral surface of the through hole H2 outward in diameter (see FIG. 12). ). Therefore, the movement of the light source 120 in the direction away from the light guide portion 112 is prevented, and the light source 120 is positioned more firmly on the holding portion 134.

次に、第２係止部１３４ｂに回路基板１２１が係止している保持部材１３０を、発光素子１２２が支持体Ｓの取付け孔Ｈ１とＺ軸方向に対向するように、支持体Ｓの第２主面Ｓ２に載置する。次いで、対向面１１１ａが第１主面Ｓ１に当接するまで、第１係止部１３３に導光部１１２を挿通させ、凸部１１２ｃを第１係止部１３３に係止させる。 Next, the holding member 130 in which the circuit board 121 is locked to the second locking portion 134b is placed on the support S so that the light emitting element 122 faces the mounting hole H1 of the support S in the Z-axis direction. 2 Placed on the main surface S2. Next, the light guide portion 112 is inserted through the first locking portion 133, and the convex portion 112c is locked to the first locking portion 133 until the facing surface 111a abuts on the first main surface S1.

本実施形態では、光出射部１１１の対向面１１１ａが支持体Ｓの第１主面Ｓ１に当接し、本体部１３１の主面Ｓ５が支持体Ｓの第２主面Ｓ２に当接する位置において、第１突起部１３３ｂと凸部１１２ｃとが係合するように設計されている。 In the present embodiment, at a position where the facing surface 111a of the light emitting portion 111 abuts on the first main surface S1 of the support S and the main surface S5 of the main body 131 abuts on the second main surface S2 of the support S. The first protrusion 133b and the protrusion 112c are designed to engage with each other.

これにより、支持体Ｓに保持部材１３０と光出射部材１１０が当接している状態が維持され、支持体Ｓに対して保持部材１３０と光出射部材１１０がガタツキなく保持されるものとなる。また、支持体Ｓの第１主面Ｓ１と光出射部１１１の対向面１１１ａとの間の隙間がなくなるため、当該隙間に異物等が混入することが防止される。 As a result, the state in which the holding member 130 and the light emitting member 110 are in contact with the support S is maintained, and the holding member 130 and the light emitting member 110 are held without rattling against the support S. Further, since there is no gap between the first main surface S1 of the support S and the facing surface 111a of the light emitting portion 111, it is possible to prevent foreign matter and the like from being mixed in the gap.

本実施形態の複数の壁部１３３ａは、弾性変形可能に構成されている。これにより、複数の壁部１３３ａは、互いに離間する方向に放射状に変形可能となる。従って、第１係止部１３３に導光部１１２を挿通させる際に、第１係止部１３３に加えられる応力が第１係止部１３３の径外方へ逃げやすくなる。従って、第１係止部１３３に導光部１１２を挿通させやすくなり、表示標識灯１００の組立性が向上する。 The plurality of wall portions 133a of the present embodiment are configured to be elastically deformable. As a result, the plurality of wall portions 133a can be deformed radially in a direction in which they are separated from each other. Therefore, when the light guide portion 112 is inserted through the first locking portion 133, the stress applied to the first locking portion 133 tends to escape to the outside of the diameter of the first locking portion 133. Therefore, the light guide portion 112 can be easily inserted into the first locking portion 133, and the assemblability of the indicator lamp 100 is improved.

特に、第１突起部１３３ｂはテーパー面Ｆ６を有するため、主面Ｓ５側から第１係止部１３３に導光部１１２を挿通させる際に、凸部１１２ｃのテーパー面Ｆ１がテーパー面Ｆ６に当接する。これにより、テーパー面Ｆ６が第１係止部１３３に導光部１１２を挿通する際の逃げ面として機能するため、上記効果がより顕著となる。 In particular, since the first protrusion 133b has a tapered surface F6, the tapered surface F1 of the convex portion 112c hits the tapered surface F6 when the light guide portion 112 is inserted from the main surface S5 side to the first locking portion 133. Contact. As a result, the tapered surface F6 functions as a flank when the light guide portion 112 is inserted into the first locking portion 133, so that the above effect becomes more remarkable.

また、凸部１１２ｃが第１係止部１３３に係止している状態においては、凸部１１２ｃのテーパー面Ｆ２と第１突起部１３３ｂのテーパー面Ｆ４とが当接し、第１突起部１３３ｂの平面Ｆ５が凸部１１２ｃ近傍の導光部１１２の外周面を挟圧している（図１２参照）。 Further, in a state where the convex portion 112c is locked to the first locking portion 133, the tapered surface F2 of the convex portion 112c and the tapered surface F4 of the first protruding portion 133b come into contact with each other, and the first protruding portion 133b The plane F5 sandwiches the outer peripheral surface of the light guide portion 112 in the vicinity of the convex portion 112c (see FIG. 12).

これにより、凸部１１２ｃが第１突起部１３３ｂに引っ掛かるだけではなく、導光部１１２が第１係止部１３３にＹ軸方向に挟圧される。従って、導光部１１２の光源１２０から離間する方向への移動が阻止され、より強固に光出射部材１１０が保持部材１３０に保持される。よって、保持部材１３０から光出射部材１１０が抜け落ちることが防止される。 As a result, not only the convex portion 112c is caught on the first projection portion 133b, but also the light guide portion 112 is pinched by the first locking portion 133 in the Y-axis direction. Therefore, the movement of the light guide unit 112 in the direction away from the light source 120 is prevented, and the light emitting member 110 is more firmly held by the holding member 130. Therefore, it is possible to prevent the light emitting member 110 from falling out of the holding member 130.

＜表示標識灯の他の構成＞
図１１は、表示標識灯１００の他の構成を示す断面図であり、表示標識灯１００を支持体Ｓに取り付けた状態を示す図である。図１２は、図１１の第１及び第２係止部１３３，１３４ｂ周辺の拡大断面図である。 <Other configurations of display indicator lights>
FIG. 11 is a cross-sectional view showing another configuration of the display indicator light 100, and is a diagram showing a state in which the display indicator light 100 is attached to the support S. FIG. 12 is an enlarged cross-sectional view of the periphery of the first and second locking portions 133 and 134b of FIG.

支持体Ｓに取り付けられた状態の表示標識灯１００では、導光部１１２が第１係止部１３３を挿通し、導光部１１２の凸部１１２ｃが第１係止部１３３に係止している。これにより、第１係止部１３３に導光部１１２が支持される。つまり、保持部材１３０が光出射部材１１０を支持するものとなる。 In the indicator lamp 100 in a state of being attached to the support S, the light guide portion 112 inserts the first locking portion 133, and the convex portion 112c of the light guide portion 112 is locked to the first locking portion 133. There is. As a result, the light guide portion 112 is supported by the first locking portion 133. That is, the holding member 130 supports the light emitting member 110.

また、第２係止部１３４ｂにおいては、回路基板１２１の貫通孔Ｈ２を挿通し、回路基板１２１が第２係止部１３４ｂに係止している。これにより、回路基板１２１が本体部１３１よりＺ軸方向上方において第２係止部１３４ｂに保持される。つまり、保持部１３４が光源１２０を保持するものとなる。 Further, in the second locking portion 134b, the through hole H2 of the circuit board 121 is inserted, and the circuit board 121 is locked to the second locking portion 134b. As a result, the circuit board 121 is held by the second locking portion 134b above the main body portion 131 in the Z-axis direction. That is, the holding portion 134 holds the light source 120.

ここで、本実施形態の本体部１３１は、台座部１３１ａと、第１係止部１３３と、保持部１３４との一体物として構成される。即ち、光出射部材１１０と光源１２０とが同一部品（本体部１３１）に保持される。これにより、光出射部材１１０と、光源１２０と、保持部材１３０のみで表示標識灯１００の装置構成を完結させることができ、部品点数の削減が可能となる。 Here, the main body portion 131 of the present embodiment is configured as an integral body of the pedestal portion 131a, the first locking portion 133, and the holding portion 134. That is, the light emitting member 110 and the light source 120 are held in the same component (main body 131). As a result, the device configuration of the display indicator lamp 100 can be completed with only the light emitting member 110, the light source 120, and the holding member 130, and the number of parts can be reduced.

また、本実施形態の表示標識灯１００は、典型的には支持体Ｓと保持部材１３０との間に設けられたスペーサ１４０を有する。これにより、凸部１１２ｃと第１突起部１３３ｂとの係止点と対向面１１１ａとの間の距離を、当該係止点と第１主面Ｓ１との間の距離と同一にすることができる。 Further, the indicator lamp 100 of the present embodiment typically has a spacer 140 provided between the support S and the holding member 130. Thereby, the distance between the locking point between the convex portion 112c and the first protrusion 133b and the facing surface 111a can be made the same as the distance between the locking point and the first main surface S1. ..

この構成により、支持体Ｓがスペーサ１４０と光出射部１１１により挟圧され、第１係止部１３３が凸部１１２ｃとスペーサ１４０により挟圧される。よって、支持体ＳのＺ軸方向の厚みや、導光部１１２のＺ軸方向の寸法に依存せずに、支持体Ｓに対して光出射部材１１０と保持部材１３０とを位置決めすることが可能となる。 With this configuration, the support S is sandwiched between the spacer 140 and the light emitting portion 111, and the first locking portion 133 is sandwiched between the convex portion 112c and the spacer 140. Therefore, it is possible to position the light emitting member 110 and the holding member 130 with respect to the support S without depending on the thickness of the support S in the Z-axis direction and the dimensions of the light guide unit 112 in the Z-axis direction. It becomes.

スペーサ１４０は支持体Ｓと保持部材１３０との間の隙間を充填可能であれば、その種類は特に限定されず、例えば合成樹脂や金属材料からなるものであってもよい。 The type of the spacer 140 is not particularly limited as long as it can fill the gap between the support S and the holding member 130, and may be made of, for example, a synthetic resin or a metal material.

なお、本実施形態のスペーサ１４０は、典型的には弾性材料からなるゴムシートである。この場合、当該ゴムシートとして、例えばポリブタンジエン系、ニトリル又はクロロプレン系材料からなるゴムシートが採用される。 The spacer 140 of the present embodiment is typically a rubber sheet made of an elastic material. In this case, as the rubber sheet, for example, a rubber sheet made of a polybutanediene-based, nitrile or chloroprene-based material is adopted.

＜作用＞
従来、鉄道等の車両において、開閉ドア近傍に取り付けられる表示標識灯（開閉予告灯）を取り付ける方法として、車体に孔を開け、取付け用のネジ座を用いて固定する方法が知られている。 <Action>
Conventionally, in a vehicle such as a railroad, as a method of attaching a display indicator light (opening / closing warning light) to be attached near an opening / closing door, a method of making a hole in a vehicle body and fixing it using a screw seat for attachment is known.

しかしながら、このような方法では、作業が大掛かりとなり、手間がかかる。また、車体に表示標識灯を取り付けるにはドリルを用いた施工だけではなく、更なる追加工が必要となるため、車体に対する加工負荷が大きくなってしまう課題がある。 However, such a method requires a large amount of work and is troublesome. Further, in order to attach the indicator light to the vehicle body, not only the construction using a drill but also further additional work is required, so that there is a problem that the processing load on the vehicle body becomes large.

これに対し、本実施形態の表示標識灯１００は、図１０に示すように、支持体Ｓに形成された取付け孔Ｈ１を介して光出射部材１１０が保持部材１３０に保持され、この保持部材１３０が光源１２０を保持する構成となっている。 On the other hand, in the display indicator lamp 100 of the present embodiment, as shown in FIG. 10, the light source member 110 is held by the holding member 130 through the mounting hole H1 formed in the support S, and the holding member 130 is held. Is configured to hold the light source 120.

つまり、本実施形態の表示標識灯１００の光出射部材１１０及び光源１２０は、車両１（支持体Ｓ）に取付け孔Ｈ１を形成する簡単な施工だけで、車両１（支持体Ｓ）に取り付けられる。 That is, the light emitting member 110 and the light source 120 of the display indicator lamp 100 of the present embodiment can be attached to the vehicle 1 (support body S) only by a simple construction for forming the attachment hole H1 in the vehicle 1 (support body S). ..

換言すると、本実施形態では、表示標識灯１００を車両１に取り付ける上で必要とされる施工が、車両１に取付け孔Ｈ１を形成する加工に限定される。従って、従来のようにネジ座を用意する必要がなくなり、車両１に取り付けられる際の手間を軽減することができる。また、車両１に対する加工が取付け孔Ｈ２の形成に限定されるため、車体に与える加工負荷が最小限に抑えられる。 In other words, in the present embodiment, the construction required for attaching the indicator light 100 to the vehicle 1 is limited to the processing of forming the attachment hole H1 in the vehicle 1. Therefore, it is not necessary to prepare a screw seat as in the conventional case, and it is possible to reduce the time and effort required to attach the screw seat to the vehicle 1. Further, since the processing for the vehicle 1 is limited to the formation of the mounting hole H2, the processing load applied to the vehicle body can be minimized.

以上のことから、車両１に取り付ける際に作業が大掛かりにならず、車体に対する加工負荷を軽減可能な表示標識灯１００を提供することができる。 From the above, it is possible to provide the display indicator light 100 that does not require a large amount of work when attached to the vehicle 1 and can reduce the processing load on the vehicle body.

例えば、上記実施形態の表示標識灯１００は、導光部１１２に形成された凸部１１２ｃが第１係止部１３３に係止する構成であるがこれに限られず、導光部１１２に形成された凹部が第１係止部１３３に係止する構成であってもよい。 For example, the display indicator lamp 100 of the above embodiment has a configuration in which the convex portion 112c formed on the light guide portion 112 is locked to the first locking portion 133, but the present invention is not limited to this, and is formed on the light guide portion 112. The concave portion may be configured to be locked to the first locking portion 133.

また、上記実施形態では、スペーサ１４０が保持部材１３０と支持体Ｓとの間に設けられるがこれに限られず、支持体Ｓと光出射部１１１との間に設けられてもよい。 Further, in the above embodiment, the spacer 140 is provided between the holding member 130 and the support S, but the present invention is not limited to this, and the spacer 140 may be provided between the support S and the light emitting portion 111.

さらに、以上の実施形態では、表示標識灯として、開閉表示灯（開閉予告灯）を例に挙げて説明したが、これに限られず、屋内外に設置される各種照明器具等にも本発明は適用可能である。また、上記表示標識灯は、室内の壁や天井に設置された照明器具として使用されてもよい。 Further, in the above embodiment, the opening / closing indicator lamp (opening / closing warning lamp) has been described as an example as the indicator lamp, but the present invention is not limited to this, and the present invention is not limited to this, and the present invention is also applied to various lighting fixtures installed indoors and outdoors.
