図１において、１は電気電子機器収納キャビネットのキャビネット本体、２は該キャビネット本体１の前面開口１１を開閉する扉である。この扉２は側方部すなわち両側方部に換気口３を形成している。４は前記換気口３を形成した側方部の裏面に設けた扉補強枠板であり、該扉補強枠板４には前記換気口３に臨む通気孔５を設けて、キャビネット本体１内と換気口３との間において空気が流出入できるものとしている。 Next, a preferred embodiment of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a cabinet body of an electric / electronic equipment storage cabinet, and 2 denotes a door that opens and closes a front opening 11 of the cabinet body 1. This door 2 forms a ventilation port 3 in a side portion, that is, both side portions. Reference numeral 4 denotes a door reinforcing frame plate provided on the back surface of the side portion where the ventilation port 3 is formed. The door reinforcing frame plate 4 is provided with a vent hole 5 facing the ventilation port 3, It is assumed that air can flow into and out of the vent 3.

また、扉２の側方部すなわち両側方部に形成した換気口３は多数のスリット３１よりなるものとしている。そして、この多数のスリット３１よりなる換気口３の複数を扉２の側方部に一列に配置している。すなわち、蝶番によりキャビネット本体１に連結する側方部には上下に５つの換気口３を、扉２の開閉用のハンドル６を取り付ける側方部には中央をハンドル取付部６１に形成してその上下に２つずつ計４つの換気口３を配置してある。換気口３を多数のスリットよりなるものとするとキャビネット本体１内に他物が入ったり悪戯される虞の無いものである。なお、換気口３を丸孔、四角孔等の小さな孔を打ち抜いた網状に形成しても、やや大きな孔に網板を嵌め込んだものであってもよい。   The ventilation port 3 formed on the side part of the door 2, that is, on both side parts, is formed of a large number of slits 31. A plurality of ventilation openings 3 made up of a large number of slits 31 are arranged in a row on the side portion of the door 2. That is, five vents 3 are formed in the upper and lower sides on the side portion connected to the cabinet body 1 by a hinge, and the center is formed in the handle attachment portion 61 on the side portion to which the handle 6 for opening and closing the door 2 is attached. A total of four ventilation openings 3 are arranged two above and below. If the ventilation port 3 is made up of a large number of slits, there is no risk of other things entering or mischief in the cabinet body 1. Note that the ventilation port 3 may be formed in a net shape in which small holes such as a round hole and a square hole are punched out, or a net plate may be fitted into a slightly larger hole.

また、前記扉補強枠板４には一列に配置した各換気口３との間に形成した間隔に相当する幅の桟４ａを設けて換気口３に臨む通気孔５を形成している。このように扉補強枠板４に桟４ａを設けて通気孔５を形成すれば、扉補強枠板４は通気孔５を設けているのに拘わらず桟４ａにより充分な強度を持って扉２を補強するものである。また、通気孔５は換気口３が臨まない桟４ａの幅分だけ閉塞されているに過ぎないので、多数のスリット３１よりなる換気口３より開口面積が広いものとなり換気口３の空気の流出入量を阻害することのないものである。   Further, the door reinforcing frame plate 4 is provided with a crosspiece 4a having a width corresponding to the interval formed between the ventilation openings 3 arranged in a row, and the ventilation holes 5 facing the ventilation openings 3 are formed. Thus, if the crosspiece 4a is provided in the door reinforcement frame plate 4 and the vent hole 5 is formed, the door reinforcement frame plate 4 has sufficient strength by the crosspiece 4a regardless of the provision of the vent hole 5. Is to reinforce. Further, since the vent hole 5 is only blocked by the width of the crosspiece 4a where the ventilation port 3 does not face, the vent hole 5 has a larger opening area than the ventilation port 3 composed of a large number of slits 31, and the outflow of air from the ventilation port 3 The amount does not hinder the amount.

また、図２−図６に示す扉補強枠板４は、通気孔５を形成した補強枠板本体４０の一方の辺の前方に扉２の側枠部２１の内面に添装する補強片部４１を折曲形成するとともに他方の辺の前方に内側補強片部４２を折曲形成したうえ該内側補強片部４２の先端に扉２の裏面に添装して取り付ける取付片部４３を折曲形成してなるものとしている。   Further, the door reinforcing frame plate 4 shown in FIGS. 2 to 6 is a reinforcing piece portion attached to the inner surface of the side frame portion 21 of the door 2 in front of one side of the reinforcing frame plate main body 40 in which the air holes 5 are formed. 41 is bent and an inner reinforcing piece 42 is bent in front of the other side, and a mounting piece 43 is attached to the tip of the inner reinforcing piece 42 and attached to the back surface of the door 2. It is supposed to be formed.

なお、扉補強枠板４は前記したものに限らず、図７に示すように通気孔５を形成した補強枠板本体４０を扉２の側枠部２１の先端から折曲形成して該補強枠板本体４０の先端に前方に向け内側補強片部４２を折曲形成したうえ該内側補強片部４２の先端に扉２の裏面に添装して取り付ける取付片部４３を折曲形成してなるものとしてもよい。   The door reinforcing frame plate 4 is not limited to the one described above, and the reinforcing frame plate main body 40 in which the air holes 5 are formed is bent from the tip of the side frame portion 21 of the door 2 as shown in FIG. An inner reinforcing piece 42 is bent forward at the front end of the frame plate main body 40, and a mounting piece 43 attached to the front end of the inner reinforcing piece 42 and attached to the back surface of the door 2 is bent. It may be.

７は扉２の中央に設けたるキャビネット本体１内を確認する四角形状の窓孔であり、該窓孔７には扉２の裏面からアクリル板よりなる透明板８が取り付けられている。透明板８は周縁を窓孔７の周縁裏面に添装したうえ前記扉補強枠板４の内側補強片部４２に透設したクリップ保持孔４２ａに着脱自在に取り付けるクリップ４２ｂにより保持して窓孔７に着脱自在に取り付けている。   A rectangular window hole 7 for confirming the inside of the cabinet body 1 provided in the center of the door 2 is attached with a transparent plate 8 made of an acrylic plate from the back surface of the door 2. The transparent plate 8 has a peripheral edge attached to the rear surface of the peripheral edge of the window hole 7 and is held by a clip 42b that is detachably attached to a clip holding hole 42a that is pierced through the inner reinforcing piece 42 of the door reinforcing frame plate 4. 7 is detachably attached.

このように構成された電気電子機器収納用キャビネットの扉構造は、扉補強枠板４を換気口３を形成した扉２の裏面に設けてあるから、扉２は中央にキャビネット本体１内を確認する四角形状の窓孔７を設けてあっても充分な強度を持つものである。また、前記扉補強枠板４は扉２の面において換気口３と併設していない構成であるから扉２の中央に設けるキャビネット本体１内を確認する窓孔７を大きく取ることができる。なお、本実施形態では扉に窓孔を設けたものを説明しているが、窓孔７を設けない場合では、扉２の機器取付スペースを大きく取ることができるという効果が得られる。   Since the door structure of the electrical / electronic equipment storage cabinet thus configured is provided with the door reinforcing frame plate 4 on the back surface of the door 2 in which the ventilation port 3 is formed, the door 2 confirms the inside of the cabinet body 1 in the center. Even if the rectangular window hole 7 is provided, it has sufficient strength. Further, since the door reinforcing frame plate 4 is not provided with the ventilation port 3 on the surface of the door 2, a large window hole 7 for confirming the inside of the cabinet body 1 provided in the center of the door 2 can be taken. In addition, although what provided the window hole in the door is demonstrated in this embodiment, when the window hole 7 is not provided, the effect that the apparatus attachment space of the door 2 can be taken large is acquired.

そして、該扉補強枠板４には前記換気口３に臨む通気孔５を設けてあるので換気口３を介して流出入する空気は通気孔５を通ってキャビネット本体内に流出入して充分な換気を行うことができるものである。なお、本実施形態では換気口３を扉２の側方部に一列に配置しているが、図８に示すように、換気口３を扉２の上下部に設けてもよい。また、換気口３は二列及びそれ以上に設けてもよいものである。   The door reinforcing frame plate 4 is provided with a vent hole 5 facing the vent 3 so that air flowing in and out through the vent 3 flows into and out of the cabinet body through the vent 5. It is possible to perform proper ventilation. In the present embodiment, the ventilation ports 3 are arranged in a row in the side portion of the door 2, but the ventilation ports 3 may be provided at the upper and lower portions of the door 2 as shown in FIG. 8. Further, the ventilation ports 3 may be provided in two rows or more.
