以下に本発明の好ましい実施形態を説明する。
図１は本発明の第１の実施形態に係る電気機器収納用箱の外観斜視図である。この実施形態の電気機器収納用箱は、支柱１と梁２と梁３とによって直方体状のフレームを構成し、その上面に天板４を取付け、前後左右の開口部は図１、図２に示すように、扉体５、側板６、背面板７などの外装パネルを取付けたものである。このように、本実施形態の電気機器収納用箱は、支柱１と梁２，３により筐体を形成し、それらによって形成される筐体の開口部を、外装パネルである扉体５、側板６、背面板７などにより覆った構造となっている。扉体５は図３に示されるように、蝶番５ａによって支柱１に取付けられている。 Hereinafter, preferred embodiments of the present invention will be described.
FIG. 1 is an external perspective view of an electric equipment storage box according to the first embodiment of the present invention. The electrical equipment storage box of this embodiment forms a rectangular parallelepiped frame by the column 1, the beam 2 and the beam 3, the top plate 4 is attached to the upper surface thereof, and the front, rear, left and right openings are shown in FIGS. As shown, exterior panels such as a door body 5, a side plate 6, and a back plate 7 are attached. Thus, the electrical equipment storage box of this embodiment forms a housing | casing by the support | pillar 1 and the beams 2 and 3, and the opening part of the housing | casing formed by them is the door body 5 which is an exterior panel, a side plate. 6. The structure is covered with a back plate 7 or the like. As shown in FIG. 3, the door body 5 is attached to the column 1 by a hinge 5a.

図３、図４に示すように、支柱１の開口部の外側には第１の排水部である水切り部１４が形成され、支柱１の開口部の内側には第２の排水部である防水片８が取付けられている。防水片８は水平断面がＬ字状であって、取付片８ａと垂直片８ｂとからなる。防水片８は支柱１の全高にわたる部材であり、その取付片８ａが支柱１に形成されている機器取付孔９にねじ１０によって取付けられている。このように防水片８を支柱１にねじ止めしたので、ねじ１０が外部に露出することがなく、防水性および外観に優れる。なお支柱１の機器取付孔９は２列に形成されていることが多く、外側の列の機器取付孔９を利用して防水片８をねじ止めすれば、内側の列の機器取付孔９を機器の取り付けに利用することができる。   As shown in FIGS. 3 and 4, a draining portion 14 that is a first drainage portion is formed outside the opening portion of the support column 1, and a waterproof that is a second drainage portion is formed inside the opening portion of the support column 1. A piece 8 is attached. The waterproof piece 8 has an L-shaped horizontal cross section and includes an attachment piece 8a and a vertical piece 8b. The waterproof piece 8 is a member extending over the entire height of the column 1, and the attachment piece 8 a is attached to the device attachment hole 9 formed in the column 1 with a screw 10. Thus, since the waterproof piece 8 is screwed to the support | pillar 1, the screw | thread 10 is not exposed outside and it is excellent in waterproofness and external appearance. The device mounting holes 9 of the support column 1 are often formed in two rows. If the waterproof strip 8 is screwed using the device mounting holes 9 in the outer row, the device mounting holes 9 in the inner row are formed. Can be used to install equipment.

防水片８の垂直片８ｂは、筐体の開口部の内側に突出するように取付けられている。図５と図６に下部の取付け状態を示し、図７に上部の取付け状態を示す。なお防水片８の取り付け方はねじ１０に限定されるものではなく、リベットやラッチによる取付けとしてもよい。なおこれらの図に示される１１は扉体５の内面に固定された機器取付用のフレーム部材である。また図３、図４に示される１２は、支柱１と外装パネルとの間に設けられたパッキンである。ただし本発明においては、パッキン１２を省略することもできる。   The vertical piece 8b of the waterproof piece 8 is attached so as to protrude inside the opening of the housing. 5 and 6 show the lower mounting state, and FIG. 7 shows the upper mounting state. The method of attaching the waterproof piece 8 is not limited to the screw 10 and may be attached by rivets or latches. In addition, 11 shown in these drawings is a frame member for equipment attachment fixed to the inner surface of the door body 5. 3 and 4 is a packing provided between the support column 1 and the exterior panel. However, in the present invention, the packing 12 can be omitted.

図３に示されるように、防水片８は支柱１と扉体５間の隙間と、支柱１よりも筐体内側に搭載される内部機器の間に位置している。この実施形態では、防水片８の垂直片８ｂは外装パネルと平行に延びており、外装パネルである扉体５に設けたフレーム部材１１との間に防水用の空間部１３を形成している。このため、パッキン１２が経年劣化して防水性が低下し、支柱１と扉体５間の隙間から水が浸入した場合にも、垂直片８ｂによって内部機器に水が掛かることを防止することができる。すなわち、支柱１と扉体５間の隙間から内部に浸入した水は防水片８に当たって流下する。このため底部には外部への排水構造を設けて置くことが望ましい。さらに、浸入する水が多量の場合であっても、空間部１３により多量の水を空間部１３内で流下させることができる。   As shown in FIG. 3, the waterproof piece 8 is positioned between the gap between the support column 1 and the door body 5 and the internal device mounted on the inner side of the casing with respect to the support column 1. In this embodiment, the vertical piece 8b of the waterproof piece 8 extends in parallel with the exterior panel, and forms a waterproof space 13 between the frame member 11 provided on the door body 5 which is the exterior panel. . For this reason, even when the packing 12 deteriorates over time and the waterproof property is lowered, and water enters from the gap between the support column 1 and the door body 5, it is possible to prevent the vertical piece 8b from splashing water on the internal device. it can. That is, the water that has entered inside through the gap between the support column 1 and the door body 5 hits the waterproof piece 8 and flows down. For this reason, it is desirable to provide an external drainage structure at the bottom. Furthermore, even when a large amount of water enters, the space portion 13 can cause a large amount of water to flow down in the space portion 13.

防水片８の取付け位置は必ずしも支柱１の扉体５側に限定されるものではなく、側板６、背面板７などの他の外装パネル側の支柱１に取付けてもよい。   The attachment position of the waterproof piece 8 is not necessarily limited to the door body 5 side of the support column 1, and may be attached to the support panel 1 on the other exterior panel side such as the side plate 6 and the back plate 7.

また図８に示すように、防水片８の垂直片８ｂが外装パネルに近い側に来るように取付けることもできる。このため、浸入した水をより手前である外装パネル付近で流下させることで、より確実に支柱１と扉体５間の隙間から内部に浸入した水が内部機器に掛かることを防止することができる。   Moreover, as shown in FIG. 8, it can also be attached so that the vertical piece 8b of the waterproof piece 8 may be on the side close to the exterior panel. For this reason, it is possible to more reliably prevent the water that has entered the interior from the gap between the support column 1 and the door body 5 from splashing on the internal device by allowing the infiltrated water to flow down near the exterior panel that is in front. .

さらに図９に示すように、防水片８の垂直片８ｂをクランク状に折り曲げた形状とすることもできる。このため、フレーム部材１１を用いない場合であっても、防水用の空間部１３を形成することができる。このように防水片８は支柱１と扉体５間の隙間から内部に浸入した水が内部機器に掛かることを防止できるものであればよく、その形状は特に限定されるものではない。   Further, as shown in FIG. 9, the vertical piece 8b of the waterproof piece 8 may be bent into a crank shape. For this reason, even when the frame member 11 is not used, the waterproof space 13 can be formed. Thus, the waterproof piece 8 should just be what can prevent that the water which permeated into the inside from the clearance gap between the support | pillar 1 and the door body 5 falls on an internal apparatus, and the shape is not specifically limited.

以上に説明した第１の実施形態は筐体がフレーム構造のものであったが、図１０に示す第２の実施形態では、筐体が支柱のないモノコック構造である。この第２の実施形態では、筐体は開口部の周囲に水切り部１４を一体に形成したものであり、開口部を覆う外装パネルである扉体５が設けられている。水切り部１４は側板６の端部を断面コ字状に屈曲させたもので、この水切り部１４の開口部内側の上下方向に沿って、防水片８が取付けられている。１２はパッキンである。   In the first embodiment described above, the housing has a frame structure, but in the second embodiment shown in FIG. 10, the housing has a monocoque structure without a support column. In the second embodiment, the casing is formed integrally with a draining portion 14 around the opening, and a door body 5 that is an exterior panel that covers the opening is provided. The draining portion 14 is obtained by bending the end of the side plate 6 into a U-shaped cross section, and a waterproof piece 8 is attached along the vertical direction inside the opening of the draining portion 14. 12 is a packing.

防水片８の構造及び取付け方法は第１の実施形態と同様であり、水切り部１４と外装パネルとの隙間から水が浸入しても、水が内部機器に掛かることを防水片８によって防止することができる。   The structure and attachment method of the waterproof piece 8 are the same as those of the first embodiment, and even if water enters from the gap between the draining portion 14 and the exterior panel, the waterproof piece 8 prevents the water from splashing on the internal device. be able to.

また、第１の実施形態と第２の実施形態のように、水切り部１４と防水片８を設けることで、水切り部１４から水が浸入しても、水が内部機器に掛かることを防水片８によって防止することで、内部機器に対して２重の防水対策を施すことが可能となる。   Further, as in the first embodiment and the second embodiment, by providing the draining portion 14 and the waterproof piece 8, even if water enters from the draining portion 14, the waterproof piece prevents water from splashing on the internal device. By preventing by 8, it becomes possible to take double waterproof measures for the internal device.

また、筐体内への水の浸入は許容しても内部機器へ水が掛かることは許容しないキュービクルなどの電気機器収納用箱には、パッキン１２を用いない場合もある。このような電気機器収納用箱であっても、第１の実施形態と第２の実施形態と同様に防水片８を設けることで、支柱１や水切部１４と外装パネルとの隙間から水が浸入しても、水が内部機器に掛かることを防水片８によって防止することができる。   Further, the packing 12 may not be used for a storage box for an electric device such as a cubicle that allows water to enter the housing but does not allow water to reach the internal device. Even in such an electric equipment storage box, by providing the waterproof piece 8 as in the first embodiment and the second embodiment, water can be supplied from the gap between the support column 1 and the draining portion 14 and the exterior panel. Even if it permeates, the waterproof piece 8 can prevent water from splashing the internal device.
