The bottom frame 5 is fixed to the gantry 6 with bolts.

以下、箱体1の組み立て手順を説明する。最初に、箱体1の設置場所に架台6を配置し、この架台6に背板3及び底枠5を取り付ける。背板3は架台6上の所定位置にボルトにより固定され、その後底枠5が取り付けられる。底枠5は、図2〜図4に示すように、背板3に当接する所定位置に配置し、背板3及び架台6にボルト23,23,・・及びネジ25,25,・・により固定される。   Hereinafter, the assembly procedure of the box 1 will be described. First, the gantry 6 is disposed at the installation location of the box 1, and the back plate 3 and the bottom frame 5 are attached to the gantry 6. The back plate 3 is fixed to a predetermined position on the gantry 6 with bolts, and then the bottom frame 5 is attached. As shown in FIGS. 2 to 4, the bottom frame 5 is disposed at a predetermined position in contact with the back plate 3, and is attached to the back plate 3 and the mount 6 by bolts 23, 23,... And screws 25, 25,. Fixed.

次に、側板2を取り付ける。図5は左側側板2aの取り付け操作を示し、図5の矢印A2に示すように、架台6に載置して前方からスライドさせて所定位置に配置する。
架台6上の底枠5を取り付けた左右側部には、側板2を設置するための空間が設けられ、側板2をこの空間に載置し、底枠5の側部に当接させながら後方に平行移動させることで、側板2はスムーズに取り付け位置に移動する。このスライド操作は、把持手段12を持つことで、作業者が側板2の内側から操作でき、簡易な操作で取り付け位置まで移動させることができる。
Next, the side plate 2 is attached. FIG. 5 shows the mounting operation of the left side plate 2a. As shown by the arrow A2 in FIG. 5, the left side plate 2a is placed on the mount 6 and slid from the front to be placed at a predetermined position.
A space for installing the side plate 2 is provided on the left and right side portions where the bottom frame 5 is mounted on the gantry 6, and the side plate 2 is placed in this space and rearward while contacting the side portion of the bottom frame 5. The side plate 2 moves smoothly to the mounting position by being translated in parallel. This slide operation has the gripping means 12 so that the operator can operate from the inside of the side plate 2 and can move to the attachment position with a simple operation.

この操作で、側板2が背板3に当接する所定位置まで移動したら、図7の矢印A3に示すように、舌片12bが背板3のスリット3bに入り込んで係合する。この舌片12bとスリット3bの係合で、側板2は所定位置での起立状態が保持される。その後、側板2は図7,8に示すように、背板3及び底枠5にネジ25,25,・・により固定され、双方に連結される。
また、側板2の下部は、後部だけでなく前部も底枠5にネジ止め(図示せず)され、右側側板2bも同様の操作で取り付けられ、ボルト23、ネジ25により連結される。
By this operation, when the side plate 2 moves to a predetermined position where it abuts on the back plate 3, the tongue piece 12b enters the slit 3b of the back plate 3 and engages as shown by an arrow A3 in FIG. By the engagement of the tongue piece 12b and the slit 3b, the side plate 2 is maintained in an upright state at a predetermined position. After that, as shown in FIGS. 7 and 8, the side plate 2 is fixed to the back plate 3 and the bottom frame 5 with screws 25, 25,.
Further, the lower part of the side plate 2 is screwed (not shown) to the bottom frame 5 as well as the rear part, and the right side plate 2b is also attached by the same operation, and is connected by a bolt 23 and a screw 25.

側板2を取り付けたら、次に天板4を取り付ける。天板4は図9の矢印A4に示すように、後部を左右側板2a,2bに載置したら、スライドさせて所定の位置に移動する。具体的に、係合片4bの後部を側板2の上端に係合させたら、側板2の平坦な上面に案内されてスムーズに後方に移動し、天板4の後端部が背板3に当接する。
こうして、スライド操作が完了したら、図10、図11に示すように、天板4は背板3に連結片17を介してボルト23,23により固定され、側板2にネジ25により固定される。また、後部だけでなく前部も同様に連結片17を介して側板2にネジ止めされる(図示せず)。
After the side plate 2 is attached, the top plate 4 is then attached. When the top plate 4 is placed on the left and right side plates 2a and 2b as shown by an arrow A4 in FIG. 9, the top plate 4 is slid to move to a predetermined position. Specifically, when the rear portion of the engagement piece 4 b is engaged with the upper end of the side plate 2, it is guided smoothly by the flat upper surface of the side plate 2, and the rear end portion of the top plate 4 is moved to the back plate 3. Abut.
When the sliding operation is completed in this way, the top plate 4 is fixed to the back plate 3 with the bolts 23 and 23 via the connecting piece 17 and fixed to the side plate 2 with screws 25 as shown in FIGS. Further, not only the rear portion but also the front portion is similarly screwed to the side plate 2 via the connecting piece 17 (not shown).

その後、図12に示すように、側板2、天板3、底枠5で形成される開口枠に対して前面枠22がネジ止め等で取り付けられ、更に図示しない扉が開閉可能に前面枠22に蝶着される。この前面枠22と背板3に形成された枠体15により、箱体1は収納される機器に対して十分な強度を発揮する。   Then, as shown in FIG. 12, the front frame 22 is attached to the opening frame formed by the side plate 2, the top plate 3, and the bottom frame 5 by screwing or the like, and the door (not shown) can be opened and closed. Butterfly. By the frame 15 formed on the front frame 22 and the back plate 3, the box 1 exhibits sufficient strength against the equipment to be stored.

このように、側板2は前方からのスライド操作により組み付けでき背板3と係合させることができるので、箱体1設置部の側方に空間が無くても、側板2を組み付けることかできる。また、その際、作業者は側板2の内側面に設けた把持手段12を把持して操作できるので、箱体1が比較的大きい場合でも側板2を容易に操作できる。そして、ボルトやネジによる連結操作も、全て箱体1内部で行うため、箱体1の外側に作業のためのスペースを必要としない。
また、背板3を枠体15により補強することで、側板2の強度を背板に比べて下げて、軽量化することができるし、スリット3bに舌片12bを挿入する簡易な構成で側板2を位置決めして保持できる。
更に、側板2を前方からスライドさせる際、底枠5にガイドさせて側板2をスライドさせれば良く、側板2の位置決めが容易である。
また、把持手段12により側板を補強するので、把持手段12を設けるために別途補強部材を必要としないし、堅牢に形成した把持手段12を介して側板2を背板3に連結するため、連結を堅牢なものにできる。
Thus, since the side plate 2 can be assembled by sliding operation from the front and can be engaged with the back plate 3, the side plate 2 can be assembled even if there is no space on the side of the box 1 installation portion. At that time, the operator can operate by gripping the gripping means 12 provided on the inner surface of the side plate 2, so that the side plate 2 can be easily operated even when the box 1 is relatively large. And since all the connection operation by a volt | bolt and a screw is also performed inside the box 1, the space for work is not required outside the box 1.
Further, by reinforcing the back plate 3 with the frame 15, the strength of the side plate 2 can be reduced as compared with the back plate, and the weight can be reduced, and the side plate can be simply configured by inserting the tongue piece 12 b into the slit 3 b. 2 can be positioned and held.
Furthermore, when the side plate 2 is slid from the front, the side plate 2 may be slid by being guided by the bottom frame 5, and the side plate 2 can be easily positioned.
Further, since the side plate is reinforced by the gripping means 12, a separate reinforcing member is not required to provide the gripping means 12, and the side plate 2 is connected to the back plate 3 via the firmly formed gripping means 12. Can be made robust.

尚、箱体1を架台6上に設置した構成を示しているが、架台6は無くても良い。この場合、架台6に取り付けられているアジャスタ7は底枠5に取り付けられる。
また、把持手段12は側板の中央に1つ設けているが、箱体1の大きさや要求される強度に応じて上下2箇所或いはそれ以上設けても良い。
In addition, although the structure which installed the box 1 on the mount frame 6 is shown, the mount frame 6 does not need to be provided. In this case, the adjuster 7 attached to the gantry 6 is attached to the bottom frame 5.
Further, although one gripping means 12 is provided at the center of the side plate, two or more upper and lower positions may be provided depending on the size of the box 1 and the required strength.
