The cover 12a is fitted into the case 14a, and the frame 11a is fixed to the case 14a with frame mounting screws (21a-1) and (21a-2). At this time, an opening surface (a flat portion (11a-3), which will be described later) that is slightly smaller than the frame 11a presses the cover pressing metal fittings (13a-1) and (13a-2) (contact portion) attached to the cover 12a. The flat portion (11a-3) of the cover 12a is pushed into and tightly attached to the cover packing 15a, and moisture and waterproof properties are ensured.

図2、図3を参照して、組み立て過程をさらに詳しく説明する。図2は、組み立て後の図1(a)をX方向からみた側面図(断面図)に相当する図である。図3は、ケース端部の周縁部分(12a−1)がカバーパッキン15aを押し圧する状態を説明するための、図2に相当する、便宜的な図である。誘導灯200が灯具取付金具17aに取り付けられている状態でケース14aにカバー12aをはめ込む。図3を参照して説明する。
(1)カバーパッキンとカバー:
ケース端部の周縁部分(12a−1)とカバーパッキン15aとは仮り組み状態で接触するようになっている。「仮り組み状態」とは、枠取付用ネジ(21a−1),(21a−2)を締めこむ直前の状態を意味する。
(2)カバー押さえ金具と枠:
仮り組み状態では、枠11aのケース側の平坦部(11a−3)は上部のカバー押さえ金具(13a−1)、及び下部のカバー押さえ金具(13a−2)に当接している。
(3)枠とケース;
また、表示灯用防水ケース110は、仮り組み状態では、枠11aのケース側の平坦部(11a−3)と、平坦部(11a−3)に対向するケース14aの平坦部(14a−3)、(14a−4)との間に、枠取付用ネジ(21a−1),(21a−2)によって締め付けられる分の隙間Bが存在するように設計されている。
(4)枠取付用ネジ(21a−1),(21a−2)を締め込んでいくと、ケース14aの平坦部(14a−3)、(14a−4)に対して枠11aの平坦部(11a−3)が近づいて行くが、このとき平坦部(11a−3)はカバー押さえ金具(13a−1)、(13a−2)に当接しているので、カバー押さえ金具(13a−1)、(13a−2)は枠11aの平坦部(11a−3)に押される。このため、枠取付用ネジ(21a−1),(21a−2)を締め込んでいくと、その締め込み量の増加に共なって、枠11aがカバー押さえ金具(13a−1)、(13a−2)をケースの方向に押し圧することにより、カバー12aの周縁部分(12a−1)によるカバーパッキン15aを押し圧する圧力が増加する。したがって、表示灯用防水ケース110は、枠取付用ネジの締め込み量の増加にともなって、カバー14aの周縁部分(12a−1)によるカバーパッキン15aを押し圧する圧力が増加する。このように枠取付用ネジ(21a−1),(21a−2)を締め込んでいくと隙間Bが小さくなっていくが、枠11a、ケース14a等の部品には剛性がある。このため、枠取付用ネジ(21a−1),(21a−2)を締め込んでいくと、結果としてカバー12aの周縁部分(12a−1)がカバーパッキン15aを押し圧する圧力が増加する。
The assembly process will be described in more detail with reference to FIGS. FIG. 2 is a view corresponding to a side view (cross-sectional view) of FIG. 1A after assembly viewed from the X direction. FIG. 3 is a schematic diagram corresponding to FIG. 2 for explaining a state in which the peripheral edge portion (12a-1) of the case end presses the cover packing 15a. The cover 12a is fitted into the case 14a in a state where the guide light 200 is attached to the lamp fixture 17a. This will be described with reference to FIG.
(1) Cover packing and cover:
The peripheral edge portion (12a-1) of the case end and the cover packing 15a are in contact with each other in a temporarily assembled state. The “temporarily assembled state” means a state immediately before the frame mounting screws (21a-1) and (21a-2) are tightened.
(2) Cover holding bracket and frame:
In the temporarily assembled state, the flat part (11a-3) on the case side of the frame 11a is in contact with the upper cover pressing metal (13a-1) and the lower cover pressing metal (13a-2).
(3) Frame and case;
Moreover, the waterproof case 110 for indicator lamps is a flat part (11a-3) by the side of the case of the frame 11a, and the flat part (14a-3) of the case 14a facing the flat part (11a-3) in the temporarily assembled state. , (14a-4) is designed such that there is a gap B that is tightened by the frame mounting screws (21a-1) and (21a-2).
(4) When the frame mounting screws (21a-1) and (21a-2) are tightened, the flat portion of the frame 11a (with respect to the flat portions (14a-3) and (14a-4) of the case 14a) 11a-3) approaches, but at this time, the flat portion (11a-3) is in contact with the cover presser fittings (13a-1) and (13a-2), so the cover presser fitting (13a-1), (13a-2) is pushed by the flat part (11a-3) of the frame 11a. For this reason, when the frame mounting screws (21a-1) and (21a-2) are tightened, the frame 11a is attached to the cover press fittings (13a-1), (13a) with the increase of the tightening amount. -2) is pressed in the direction of the case to increase the pressure for pressing the cover packing 15a by the peripheral portion (12a-1) of the cover 12a. Therefore, in the waterproof case for indicator lamp 110, the pressure for pressing the cover packing 15a by the peripheral portion (12a-1) of the cover 14a increases as the amount of tightening of the frame mounting screw increases. As the frame mounting screws (21a-1) and (21a-2) are tightened in this way, the gap B decreases, but the parts such as the frame 11a and the case 14a are rigid. For this reason, when the frame mounting screws (21a-1) and (21a-2) are tightened, the pressure at which the peripheral portion (12a-1) of the cover 12a presses the cover packing 15a increases as a result.

このように、表示灯用防水ケース120は、カバー押さえ部(11b−1)、(11b−2)が枠11bと一体となった構造である。枠11bの内側にカバー12b側面と平行に接する部分(前述のカバー押さえ部)を設ける。カバー12bと枠11bとは側面の接した部分でネジ(22b−1)〜(22b−4)により固定し、一体化する。枠11bをケース14bに枠取付用ネジ(21b−1),(21b−2)で固定することにより、カバー12bがケース14b側に押し込まれて周縁部分(12b−1)がカバーパッキン15bを押し圧して密閉構造を形成する。   Thus, the waterproof case 120 for display lamps has a structure in which the cover pressing portions (11b-1) and (11b-2) are integrated with the frame 11b. A portion (the above-described cover pressing portion) in contact with the side surface of the cover 12b is provided inside the frame 11b. The cover 12b and the frame 11b are fixed by screws (22b-1) to (22b-4) at a portion where the side surfaces are in contact, and are integrated. By fixing the frame 11b to the case 14b with frame mounting screws (21b-1) and (21b-2), the cover 12b is pushed into the case 14b and the peripheral portion (12b-1) pushes the cover packing 15b. To form a sealed structure.

図6に示すように、カバー押さえ部(11b−5),(11b−6)は、例えば、枠11bに残された平板部分を矢印の方向に折り曲げて形成する。このように、枠11bの小さい開口面側の少なくとも2辺に側壁であるカバー押さえ部(11b−5)、(11b−6)を設け、カバー押さえ部(11b−5)、(11b−6)にカバー12bをネジ(22b−1)〜(22b−4)にて固定する。これにより、カバー12bと枠11bとは、予め一体に組みつけられる。図7(B−B断面図)は、カバー12bと枠11bとのネジどめ状態を示している。   As shown in FIG. 6, the cover pressing portions (11b-5) and (11b-6) are formed, for example, by bending a flat plate portion left on the frame 11b in the direction of the arrow. As described above, the cover pressing portions (11b-5) and (11b-6) which are side walls are provided on at least two sides on the small opening surface side of the frame 11b, and the cover pressing portions (11b-5) and (11b-6) are provided. The cover 12b is fixed with screws (22b-1) to (22b-4). Thereby, the cover 12b and the frame 11b are assembled together in advance. FIG. 7 (BB sectional view) shows a screwed state of the cover 12b and the frame 11b.

(組み立て工程)
組み立て時、枠11bをケース14bに枠取付用ネジ(21a−1),(21a−2)で取り付ける過程で、カバー12bの周縁部分(12b−1)がカバーパッキン15bに押し込まれる。これにより、防湿、防水性を確保する構成となっている。
(Assembly process)
During assembly, in the process of attaching the frame 11b to the case 14b with frame attaching screws (21a-1) and (21a-2), the peripheral portion (12b-1) of the cover 12b is pushed into the cover packing 15b. Thereby, it is the structure which ensures moisture proof and waterproofness.

すなわち、表示灯用防水ケース120は、表示灯用防水ケース110に対して、カバー押さえ金具(13a−1)、(13a−2)をカバー押さえ部(11b−5)、(11b−6)とした構成が異なるのみであり、ケース14bはケース14aと同じ構成である。予め枠11bがネジどめされたカバー12bをケース14bに仮り組みすると、表示灯用防水ケース110の場合と同様に、枠11bとケース14bとの相対位置は、図3と同じ状態となるように設計されている。つまり、表示灯用防水ケース110と同様に、表示灯用防水ケース120は仮り組み状態において隙間Bが存在するように設計されており、枠取付用ネジ(21b−1),(21b−2)を締め込んでいくと隙間Bが小さくなっていくが、枠11b、ケース14b等の部品には剛性がある。このため、枠取付用ネジ(21b−1),(21b−2)を締め込んでいくと、結果としてカバー12bの周縁部分(12b−1)がカバーパッキン15bを押し圧する圧力が増加する。   That is, the waterproof case 120 for indicator lamps has the cover holders (13a-1) and (13a-2) as cover holders (11b-5) and (11b-6) with respect to the waterproof case 110 for indicator lights. However, the case 14b is the same as the case 14a. When the cover 12b, in which the frame 11b is screwed in advance, is temporarily assembled to the case 14b, the relative position between the frame 11b and the case 14b is the same as in FIG. Designed to. That is, similar to the waterproof case 110 for the indicator lamp, the waterproof case 120 for the indicator lamp is designed so that there is a gap B in the temporarily assembled state, and the frame mounting screws (21b-1) and (21b-2) The gap B becomes smaller as the screw is tightened, but the parts such as the frame 11b and the case 14b are rigid. For this reason, when the frame mounting screws (21b-1) and (21b-2) are tightened, the pressure at which the peripheral portion (12b-1) of the cover 12b presses the cover packing 15b increases as a result.

実施の形態3.
図8を参照して実施の形態3の表示灯用防水ケース130を説明する。表示灯用防水ケース130は、枠11とカバー12とが一体化された表示灯用防水ケースである。表示灯用防水ケース130は、カバー12cのみで密閉を形成するタイプである。カバー12cをカバー取付用ネジ(21c−1),(21c−2)により直接ケース14cのカバー取付金具(18c−1)、(18c−2)に固定する。カバー取付用ネジ(21c−1),(21c−2)を締めていくことにより、カバー12cの周縁部分(12c−1)がカバーパッキン15cを押し圧して密閉構造を形成する。また、カバー12cの形状を、中心部が高く、周辺部が低くなった段状に成形することで、カバー12cの剛性が強まり、カバー取付用ネジ(21c−1),(21c−2)をより強く締めることができる。このため、周縁部分(12c−1)とカバーパッキン15cとの密着性が増し、カバー12cとケース14cとの密閉度を高めることができる。
Embodiment 3 FIG.
With reference to FIG. 8, the waterproof case 130 for indicator lights of Embodiment 3 is demonstrated. The indicator lamp waterproof case 130 is an indicator lamp waterproof case in which the frame 11 and the cover 12 are integrated. The waterproof case for indicator lamp 130 is a type that forms a hermetic seal only with the cover 12c. The cover 12c is directly fixed to the cover mounting brackets (18c-1) and (18c-2) of the case 14c by the cover mounting screws (21c-1) and (21c-2). By tightening the cover mounting screws (21c-1) and (21c-2), the peripheral portion (12c-1) of the cover 12c presses the cover packing 15c to form a sealed structure. Further, by forming the cover 12c into a step shape having a high center part and a low peripheral part, the rigidity of the cover 12c is increased, and the cover mounting screws (21c-1) and (21c-2) are attached. It can be tightened more strongly. For this reason, the adhesiveness of a peripheral part (12c-1) and the cover packing 15c increases, and the sealing degree of the cover 12c and the case 14c can be improved.

カバー12cは枠11とカバー12とを一体化した形状である。ケース14cは、実施の形態1のケース14aに対して、平坦部(14a−3),(14a−4)に対応するカバー取付金具(18c−1)、(18c−2)を備える構成である。   The cover 12c has a shape in which the frame 11 and the cover 12 are integrated. The case 14c is configured to include cover mounting brackets (18c-1) and (18c-2) corresponding to the flat portions (14a-3) and (14a-4) with respect to the case 14a of the first embodiment. .

(組み立て工程)
カバー12cには開口面と対面側に少なくとも2ヶ所のカバー取付用ネジの貫通する貫通穴(11c−1)、(11c−2)を設けている。カバー12cをケース14cにはめ込み、仮り組みする。この仮り組みの状態において、表示灯用防水ケース130は、図3のように、ケース端部の周縁部分(12c−1)とカバーパッキン15cとが接触するようになっている。また、この仮り組み状態では、カバー12cのケース14c側の平坦部(11c−3)(鍔部12c−4の一部である)と、この平坦部(11c−3)に対向するカバー取付金具(18c−1)、(18c−2)の平坦部(14c−3)、(14c−4)との間に、カバー取付用ネジ(21c−1),(21c−2)によって締め付けられる分の隙間Bが存在するように設計されている。カバー取付用ネジ(21c−1),(21c−2)を締め込んでいくと平坦部(14c−3)、(14c−4)に対してカバー12cの平坦部(11c−3)が近づいて行くが、カバー12c、カバー取付金具18c等の部品には剛性がある。このため、カバー取付用ネジ(21c−1),(21c−2)を締め込んでいくと、結果として、カバー12cの周縁部分(12c−1)がカバーパッキン15cを押し圧する圧力が増加する。
(Assembly process)
The cover 12c is provided with through holes (11c-1) and (11c-2) through which at least two cover mounting screws pass on the side facing the opening. The cover 12c is fitted into the case 14c and temporarily assembled. In this temporarily assembled state, the waterproof case for indicator lamp 130 is configured such that the peripheral edge portion (12c-1) of the case end and the cover packing 15c are in contact with each other as shown in FIG. In this temporarily assembled state, the flat part (11c-3) (which is a part of the flange part 12c-4) on the case 14c side of the cover 12c and the cover mounting bracket facing the flat part (11c-3) Between the flat parts (14c-3) and (14c-4) of (18c-1) and (18c-2), the parts to be tightened by the cover mounting screws (21c-1) and (21c-2) The gap B is designed to exist. When the cover mounting screws (21c-1) and (21c-2) are tightened, the flat portion (11c-3) of the cover 12c approaches the flat portions (14c-3) and (14c-4). However, parts such as the cover 12c and the cover mounting bracket 18c are rigid. Therefore, when the cover mounting screws (21c-1) and (21c-2) are tightened, as a result, the pressure with which the peripheral portion (12c-1) of the cover 12c presses the cover packing 15c increases.

カバー12cは図8のように、開口面と対面側が2段となっている。図8(b)に示すように、カバー12cは、開口を有する略箱状の箱形状部(12c−6)と、箱形状部(12c−6)の開口の周縁に形成された鍔形状の鍔部(12c−4)と、鍔部(12c−4)から箱形状部(12c−6)の4つの側面(12c−3)の起立する方向にそれぞれ対応して起立した4つの側面からなる側面部(12c−5)と有している。そして、仮り組み状態において側面部(12c−5)の端部(周縁部分12c−1)は、カバーパッキン15cと接触する。このように、カバー12cの曲部が増えることにより、カバー12cの剛性が高まり、カバー取付用ネジ(21c−1),(21c−2)で固定した場合、カバー12cの変形をより抑えられるとともに、このネジで締めていく際、カバー12cをカバーパッキン15cにより強く押し込むことができるので防湿、防水性がより高まる。   As shown in FIG. 8, the cover 12c has two steps on the opening surface and the facing side. As shown in FIG. 8 (b), the cover 12c has a substantially box-shaped box-shaped part (12c-6) having an opening and a bowl-shaped part formed on the periphery of the opening of the box-shaped part (12c-6). It consists of a collar part (12c-4) and four side surfaces that stand up corresponding to the direction in which the four side surfaces (12c-3) of the box-shaped part (12c-6) stand up from the collar part (12c-4). It has a side part (12c-5). In the temporarily assembled state, the end portion (peripheral portion 12c-1) of the side surface portion (12c-5) is in contact with the cover packing 15c. Thus, the increase in the number of curved portions of the cover 12c increases the rigidity of the cover 12c. When the cover 12c is fixed with the cover mounting screws (21c-1) and (21c-2), deformation of the cover 12c can be further suppressed. When tightening with this screw, the cover 12c can be pushed in more strongly by the cover packing 15c, so that moisture resistance and waterproofness are further improved.
