本実施の形態を、防災機器の一例として火災受信機を例に挙げて図１〜図４に基づいて説明する。
本実施の形態に係る火災受信機１は、図１に示すように、金属製の本体３と扉５を有し、扉５に設けた開口部７（図２参照）に液晶ディスプレイ９等を搭載した樹脂製のパネルユニット１１を着脱可能に取り付けられるようにしたものである。本実施の形態の説明においては、液晶ディスプレイ９をパネルユニット１１に搭載し、液晶ディスプレイ９を扉５に取り付けるための表示パネルユニット１１として説明するが、パネルユニット１１はスイッチ等の操作部またはプリンタを搭載しもよいし、それらの複数を搭載するようにしてもよい。
以下、各構成を詳細に説明する。 The present embodiment will be described based on FIGS. 1 to 4 by taking a fire receiver as an example of the disaster prevention device.
As shown in FIG. 1, the fire receiver 1 according to the present embodiment has a metal main body 3 and a door 5, and a liquid crystal display 9 etc. is provided in an opening 7 (see FIG. 2) provided in the door 5. The mounted resin panel unit 11 can be detachably attached. Although the liquid crystal display 9 is mounted on the panel unit 11 and the liquid crystal display 9 is described as the display panel unit 11 for attaching the door 5 in the description of the present embodiment, the panel unit 11 is an operation unit such as a switch or a printer May be mounted, or a plurality of them may be mounted.
Each configuration will be described in detail below.

＜扉＞
扉５は本体３に開閉可能に取り付けられており、矩形の開口部７を有している。扉５の内面側における開口部７の左右縁と下縁には、図２に示すように、表示パネルユニット１１に設けられた後述の係止片２３が係止可能な係止部としての係止孔１３が設けられた板状体からなる係止部材１５が設けられている。
また、扉５の内面側の開口部７の上縁及び下縁のそれぞれにネジ固定ボス１７がそれぞれ２本立設されている。 <Door>
The door 5 is attached to the main body 3 so as to be openable and closable, and has a rectangular opening 7. As shown in FIG. 2, on the left and right edges and the lower edge of the opening 7 on the inner surface side of the door 5, engaging portions as engaging portions capable of being engaged with engaging pieces 23 described later provided on the display panel unit 11 The locking member 15 which consists of a plate-shaped body in which the stop hole 13 was provided is provided.
Further, two screw fixing bosses 17 are respectively provided upright on the upper edge and the lower edge of the opening 7 on the inner surface side of the door 5.

＜表示パネルユニット＞
表示パネルユニット１１は、液晶ディスプレイ９が設置される窓部１９を有する矩形の樹脂製の枠部２１からなり、枠部２１には複数の係止片２３が設けられている。
本実施の形態では、枠部２１の左右辺のそれぞれに３個と、枠部２１の下辺に１個の係止片２３が設けられている。各係止片２３は、図２の拡大図に示すように、枠部２１と同じ面に、その両側と枠部２１との間にスリットを介して設けられた板状の片部からなり、下部（図中右側）を基端として撓むことができる。各係止片２３はその上部（図中左側）に係止爪２５を有している。
また、係止片２３の肉厚は、枠部２１の肉厚よりも薄く設定されている。これによって、係止片２３が撓みやすくなり、取り付けの際の装着を容易にできる。 <Display panel unit>
The display panel unit 11 is formed of a rectangular resin frame 21 having a window 19 on which the liquid crystal display 9 is installed, and the frame 21 is provided with a plurality of locking pieces 23.
In the present embodiment, three locking pieces 23 are provided on the left and right sides of the frame 21 and one locking piece 23 on the lower side of the frame 21. As shown in the enlarged view of FIG. 2, each locking piece 23 is formed of a plate-shaped piece provided on the same surface as the frame 21 with slits between the frame 21 and both sides thereof. The lower part (right side in the figure) can be bent as a base end. Each locking piece 23 has a locking claw 25 at its upper portion (left side in the drawing).
In addition, the thickness of the locking piece 23 is set to be thinner than the thickness of the frame portion 21. By this, the locking piece 23 becomes easy to bend, and the attachment at the time of attachment can be made easy.

枠部２１における係止片２３が設けられた箇所には、係止片２３を内側に迂回して枠部２１と連続するように補強壁２７が設けられている。
補強壁２７を設けることで、枠部２１と同じ面にスリットを介して係止片２３を設けたとしても、枠部２１の剛性を確保できる構造になっている。
補強壁２７は、係止片２３の内側に係止片２３との間に隙間を介して設けられており、係止片２３が内側に撓むのを邪魔することはない。その一方で、係止片２３がある程度内側に撓むと、係止片２３が補強壁２７に当接するので、係止片２３が撓みすぎるのを防止する機能も有している。 At a portion of the frame portion 21 where the locking piece 23 is provided, a reinforcing wall 27 is provided so as to bypass the locking piece 23 inward and to be continuous with the frame portion 21.
By providing the reinforcing wall 27, even when the locking piece 23 is provided on the same surface as the frame 21 via the slit, the rigidity of the frame 21 can be secured.
The reinforcing wall 27 is provided on the inside of the locking piece 23 with a gap between the locking piece 23 and the locking piece 23, and does not disturb the locking piece 23 from being bent inward. On the other hand, when the locking piece 23 bends inward to a certain degree, the locking piece 23 abuts against the reinforcing wall 27, so it also has a function to prevent the locking piece 23 from being bent too much.

係止片２３の肉厚を薄く設定できたのは、補強壁２７を設けることで枠部２１の剛性を確保できているからであり、係止片２３の肉厚は枠部２１の剛性とは関係なく操作性のみに基づいて適宜設定することができる。   The reason why the thickness of the locking piece 23 can be set thin is that the rigidity of the frame portion 21 can be secured by providing the reinforcing wall 27, and the thickness of the locking piece 23 is the rigidity of the frame portion 21. Can be appropriately set based on operability alone.

表示パネルユニット１１の枠部２１の上辺及び下辺には、ブラケット２９が設けられ、ブラケット２９にはネジ固定ボス１７が遊貫できる孔部３１が設けられている。   A bracket 29 is provided on the upper side and the lower side of the frame portion 21 of the display panel unit 11, and the bracket 29 is provided with holes 31 through which the screw fixing bosses 17 can freely pass.

上記のように構成された表示パネルユニット１１を扉５に装着する際には、扉５の内面側から表示パネルユニット１１を扉５の開口部７に近づけて、各係止片２３と係止孔１３の位置合わせをした状態で、表示パネルユニット１１を前方に押し込むようにする。これによって、係止片２３が撓んで係止爪２５が係止孔１３に係止する（図３参照）。
このとき、ネジ固定ボス１７はブラケット２９の孔部３１に遊貫され図３及び図４に示すように、ネジ固定ボス１７と孔部３１との間には所定の隙間が形成された状態になる。この状態で、図４に示すように、ネジ固定ボス１７に固定ネジ３３を取り付けることで装着が完了する。 When the display panel unit 11 configured as described above is attached to the door 5, the display panel unit 11 is brought close to the opening 7 of the door 5 from the inner surface side of the door 5 and engaged with the locking pieces 23. With the holes 13 aligned, the display panel unit 11 is pushed forward. As a result, the locking piece 23 bends and the locking claw 25 locks in the locking hole 13 (see FIG. 3).
At this time, as shown in FIGS. 3 and 4, the screw fixing boss 17 is loosely inserted in the hole 31 of the bracket 29, and a predetermined gap is formed between the screw fixing boss 17 and the hole 31. Become. In this state, as shown in FIG. 4, the attachment is completed by attaching the fixing screw 33 to the screw fixing boss 17.

上記のように構成された本実施の形態の作用効果を説明する。
本実施の形態では、枠部２１の外形状が扉５の開口部７の形状とほぼ同形状として、扉５の内側から表示パネルユニット１１を装着できるようにしたので、開口部７に表示パネルユニット１１が丁度嵌りこむように設置することができ、表示パネルユニット１１と扉５の前面とを略面一にすることができ、意匠性に優れている。 The operation and effect of the present embodiment configured as described above will be described.
In the present embodiment, the outer shape of the frame portion 21 is substantially the same as the shape of the opening 7 of the door 5, and the display panel unit 11 can be attached from the inside of the door 5. The unit 11 can be installed so as to fit in exactly, the display panel unit 11 and the front surface of the door 5 can be made approximately flush, and the design is excellent.

従来例のように、表示パネルユニットの全周にフランジがある場合には、表示パネルユニットを装着した状態で、フランジが扉の開口縁に当接する。このため、表示パネルユニットの操作時に押圧荷重が作用してもフランジが反力受けとなって表示パネルユニットが撓むことがない。
この点、本実施の形態は、フランジを有しておらず、操作時の荷重を受けるのは枠部２１となるため、荷重によって枠部２１が撓み、係止片２３に荷重が集中することが考えられる。しかし、本実施の形態のように、補強壁２７を設けて枠部２１が全周に亘って連続する構造にしていることで、枠部２１の剛性が確保されて撓みにくくなっているので、係止片２３に荷重が集中することなく係止が外れることがない。
つまり、表示パネルユニット１１を扉５の内側から装着が可能な構造にしたことで、フランジを無くする必要があるが、フランジを無くしたことによる枠部２１の剛性の低下を、補強壁２７を設けることで補うようにしていると言える。 As in the conventional example, in the case where the display panel unit has a flange all around, the flange abuts on the opening edge of the door with the display panel unit attached. For this reason, even if a pressing load is applied when operating the display panel unit, the flange does not receive a reaction force and the display panel unit is not bent.
In this point, in the present embodiment, since the frame 21 is not provided with a flange and receives the load at the time of operation, the frame 21 is bent by the load and the load is concentrated on the locking piece 23. Is considered. However, as in the present embodiment, by providing the reinforcing wall 27 and making the frame 21 continuous over the entire circumference, the rigidity of the frame 21 is secured and it is difficult to bend, The load does not concentrate on the locking piece 23 and the locking is not released.
In other words, it is necessary to eliminate the flange by making the display panel unit 11 mountable from the inside of the door 5, but the reduction of the rigidity of the frame 21 due to the elimination of the flange It can be said that it makes it to compensate by providing.

また、補強壁２７を設けることで、係止片２３には自身による枠の剛性確保の必要がなくなったため、係止片２３の板厚を薄くすることができ、表示パネルユニット１１の装着の際の動作がスムーズになっている。   Further, by providing the reinforcing wall 27, the locking piece 23 is not required to secure the rigidity of the frame by itself, so that the thickness of the locking piece 23 can be reduced, and the display panel unit 11 can be mounted. The operation of is smooth.

さらに、ブラケット２９とネジ固定ボス１７によってネジ固定するようにしたことで、操作等で火災受信機１の正面に大きな力が作用したときに表示パネルユニット１１が外れることがない。
また、ブラケット２９の孔部３１とネジ固定ボス１７との間には隙間があるので、温度変化で金属製の扉５の変形（膨張や収縮）よりも、樹脂製の表示パネルユニット１１のほうが大きく変形したとしても、ネジ固定ボス１７と孔部３１は面内（扉５の開口部７を有する面と水平）での移動が可能になっているので、ネジ固定ボス１７を起点として変形することを防止できる。このため、例えば扉５側に係合している係止片２３が収縮により、ネジ固定ボス１７側に引き寄せられて外れてしまうことを防止することができる。
なお、図４に示すように、表示パネルユニット１１に段部３５を設け、表示パネルユニット１１が扉５の内側で扉５の開口部７よりも大きくすることで、温度変化により収縮変形したとしても、段部３５により開口部７との隙間が生じることなく、扉５の内側が見えるというおそれがない。 Further, since the screws are fixed by the bracket 29 and the screw fixing bosses 17, the display panel unit 11 is not detached when a large force is applied to the front of the fire receiver 1 by an operation or the like.
In addition, since there is a gap between the hole 31 of the bracket 29 and the screw fixing boss 17, the display panel unit 11 made of resin is better than the deformation (expansion or contraction) of the metal door 5 due to temperature change. Even if it is greatly deformed, the screw fixing boss 17 and the hole 31 can be moved in a plane (horizontal to the plane having the opening 7 of the door 5), so the screw fixing boss 17 is deformed as a starting point Can be prevented. For this reason, it is possible to prevent, for example, the locking piece 23 engaged on the door 5 side from being pulled close to the screw fixing boss 17 side due to contraction and coming off.
Note that, as shown in FIG. 4, the display panel unit 11 is provided with a step 35, and the display panel unit 11 is made larger than the opening 7 of the door 5 inside the door 5, thereby causing contraction and deformation due to temperature change. Also, there is no fear that the inside of the door 5 can be seen without a gap with the opening 7 being generated by the step 35.
