Description

本発明は、装置筐体に関するものである。   The present invention relates to an apparatus housing.

保守用の開口部を扉体で開放可能に閉塞した電子装置筐体としては、例えば特許文献１に記載されたものが知られている。この従来例において、装置筐体のフレームには先端に球体が固定されたワイヤが連結され、扉体側にはガイド部材が固定される。   As an electronic device casing in which a maintenance opening is closed with a door so as to be openable, for example, one described in Patent Document 1 is known. In this conventional example, a wire having a sphere fixed at its tip is connected to the frame of the apparatus housing, and a guide member is fixed to the door body side.

ガイド部材には孔が形成され、該孔にワイヤの球体を係止させることにより扉体の開放角度を規制することができる。
特開２００３-１３８８２６号公報 A hole is formed in the guide member, and the opening angle of the door body can be regulated by locking the sphere of the wire in the hole.
JP 2003-138826 A

しかし、上述した従来例は扉の開放角度の規制がワイヤ長により一律に決定されてしまうために、通常の運用時に比して大きな開放角が必要な作業、例えば、筐体内の保守作業時の作業性が低下する等、運用の融通性が低いという問題がある。   However, in the above-described conventional example, the restriction on the opening angle of the door is uniformly determined by the wire length, so that work that requires a larger opening angle than during normal operation, for example, during maintenance work in the housing. There is a problem that the flexibility of operation is low, such as a decrease in workability.

上記問題を解決するために、ワイヤのガイド部材との係止を解除することも可能であるが、この場合、扉体の回転角規制が全く効かなくなるために、かえって作業性が悪化したり、あるいはワイヤの再連結忘れが生じる等の問題がある。   In order to solve the above problem, it is also possible to release the lock with the guide member of the wire, but in this case, since the rotation angle regulation of the door body is not effective at all, the workability deteriorates on the contrary, Or there is a problem such as forgetting to reconnect the wires.

本発明は、以上の欠点を解消すべくなされたものであって、運用の融通性の高い装置筐体の提供を目的とする。   The present invention has been made to solve the above-described drawbacks, and an object of the present invention is to provide an apparatus housing having high operational flexibility.

装置筐体はフレーム１の開口２を扉体３により開放操作可能に閉塞して形成され、いずれか一方に紐状体５が連結され、他方に係止部６が固定される。紐状体５は全体として屈曲自在であり、適宜間隔で配置される被係止部４のいずれか一を係止部６に係止させると、紐状体５の一端と係止部６への係止端との間の余裕長により扉体３の開放許容角度が規制される。   The device housing is formed by closing the opening 2 of the frame 1 by a door body 3 so that the opening operation is possible, and a string-like body 5 is connected to one of them and a locking portion 6 is fixed to the other. The string-like body 5 can be bent as a whole, and when any one of the locked parts 4 arranged at appropriate intervals is locked to the locking part 6, the string-like body 5 is connected to one end of the string-like body 5 and the locking part 6. The allowable opening angle of the door body 3 is regulated by a margin length between the first and second locking ends.

係止部６に係止して扉体３の開放許容角度を決定する被係止部４が複数設けられる本発明において、装置筐体への作業内容に応じて係止部６に対する被係止部４を選択するだけで開放許容角度を自由に調整することができる。また、調整後も扉体３の開放許容角度の規制が行われ、規制が完全に解除されるわけではないので、扉体３の拘束解除に基づく作業性の低下が生じない。   In the present invention in which a plurality of locked portions 4 that are locked to the locking portion 6 and determine the allowable opening angle of the door body 3 are provided, the locked portion 6 is locked according to the work content of the apparatus housing. The opening allowable angle can be freely adjusted by simply selecting the portion 4. Further, even after the adjustment, the allowable opening angle of the door body 3 is regulated, and the regulation is not completely released, so that the workability due to the release of the restraint of the door body 3 does not occur.

本発明によれば、作業内容によって扉体の開放許容角度を適宜に変更できるために、運用の融通性を高めることができる。   According to the present invention, the door opening allowance angle can be changed as appropriate according to the work contents, so that the flexibility of operation can be improved.

図１に示すように、装置筐体Ａは正面に開口２を備えたフレーム１と、フレーム１の開口２を閉塞する扉体３から構成される。扉体３は、縦方向一側縁が図外のヒンジによりフレーム１に軸支され、水平回転することができる。   As shown in FIG. 1, the device casing A is composed of a frame 1 having an opening 2 on the front surface and a door body 3 that closes the opening 2 of the frame 1. The door body 3 is pivotally supported on the frame 1 by a hinge that is not shown in the vertical direction and can rotate horizontally.

９はストッパ装置であり、扉体３のヒンジ側辺縁に固定される係止部材８と、フレーム１側に固定される紐状体５とからなる。紐状体５は、細径部７と被係止部４とを交互に長手方向に配置してワイヤ状に形成される。この紐状体５は、図２（ａ）に示すように、一端に形成されたワッシャ状の固定リング５ａによりフレーム１に取り付けられる。   Reference numeral 9 denotes a stopper device, which includes a locking member 8 fixed to a hinge side edge of the door body 3 and a string-like body 5 fixed to the frame 1 side. The string-like body 5 is formed in a wire shape by alternately arranging the narrow diameter portions 7 and the locked portions 4 in the longitudinal direction. As shown in FIG. 2A, the string-like body 5 is attached to the frame 1 by a washer-like fixing ring 5a formed at one end.

この実施の形態において紐状体５は、自由に屈曲させることができる程度に細径のワイヤ上に適宜間隔で球状の太径部材４Ａを固定して形成され、ワイヤ露出部が細径部７に、太径部材４Ａ固定部が被係止部４となる。太径部材４Ａは、ワイヤ上に圧着、あるいは溶着して固定され、必要に応じて、例えばワイヤに結び目を作る等してずれ止めされる。   In this embodiment, the string-like body 5 is formed by fixing spherical large-diameter members 4A at appropriate intervals on a thin-diameter wire to such an extent that the string-like body 5 can be bent freely. In addition, the fixed portion of the large diameter member 4 </ b> A becomes the locked portion 4. The large-diameter member 4A is fixed by crimping or welding on the wire, and is prevented from being displaced, for example, by knotting the wire.

一方係止部材８は、図２（ｂ）に示すように、水平片８ａの一側端縁から上方に延設される係止片８ｂを有し、水平片８ａの他側縁から下方に延設される固定片８ｃにおいて扉体３裏面に固定される。   On the other hand, as shown in FIG. 2B, the locking member 8 has a locking piece 8b extending upward from one side edge of the horizontal piece 8a, and downward from the other side edge of the horizontal piece 8a. The fixed piece 8c that is extended is fixed to the back surface of the door body 3.

係止片８ｂには上縁に開放されるスリット状の係止部６が形成される。図２、３に示すように、係止部６はクランク形状を有し、上記ワイヤ（紐状体５の細径部７）が通過可能で、かつ太径部材４Ａが挿通不能な幅寸法（Ｗ）に形成される。   The locking piece 8b is formed with a slit-shaped locking portion 6 opened to the upper edge. As shown in FIGS. 2 and 3, the locking portion 6 has a crank shape, the width dimension (through which the wire (the small diameter portion 7 of the string-like body 5) can pass and the large diameter member 4 </ b> A cannot be inserted). W).

また、水平片８ａは、扉体３に固定した状態で係止片８ｂと扉体３裏面との間に上記被係止部４が挿通可能な隙間が確保される程度の奥行寸法（Ｌ）に形成される（図３（ｂ）参照）。   Further, the horizontal piece 8a has a depth dimension (L) such that a clearance is secured between the locking piece 8b and the back surface of the door 3 so that the locked portion 4 can be inserted in a state where the horizontal piece 8a is fixed to the door 3. (See FIG. 3B).

したがってこの実施の形態において、使用に際し、一端がフレーム１に固定された紐状体５の太径部材４Ａを係止部材８に係止させるようにして細径部７をスリット６に挿入する。この状態で紐状体５は、図３（ｃ）に示すように、係止部材８への係止部６とフレーム１への固定部が拘束されており、中間部は扉体３とフレーム１との隙間に収納される。これから、図１（ａ）に示すように、扉体３を回転させて適宜回転角に達すると、中間部の遊びがなくなり、扉体３の開放角度が規制される。   Therefore, in this embodiment, in use, the small-diameter portion 7 is inserted into the slit 6 so that the large-diameter member 4A of the string-like body 5 whose one end is fixed to the frame 1 is locked to the locking member 8. In this state, as shown in FIG. 3C, the string-like body 5 is restrained by the locking portion 6 to the locking member 8 and the fixing portion to the frame 1, and the middle portion is the door 3 and the frame. 1 is accommodated in a gap with 1. From this, as shown in FIG. 1A, when the door body 3 is rotated and the rotation angle is appropriately reached, there is no play in the intermediate portion, and the opening angle of the door body 3 is restricted.

この状態から、太径部材４Ａの係止部材８への係止位置を変更すると、図１（ｂ）に示すように、中間部の長さが変わるために、扉体３の開放許容角度が変更される。   If the locking position of the large-diameter member 4A to the locking member 8 is changed from this state, as shown in FIG. Be changed.

図４に紐状体５の変形例を示す。この変形例において紐状体５は、杆部１０ａの両端に球状膨隆部１０ｂが形成された亜鈴状部材１０と、亜鈴状部材１０間を連結する連結部材４Ｂとからなる。連結部材４Ｂは亜鈴状部材１０の球状膨隆部１０ｂが収容可能な両端が閉塞された筒体で、中央部には球状膨隆部１０ｂが挿通可能な膨隆部挿入開口４ａが開設される。   FIG. 4 shows a modification of the string-like body 5. In this modification, the string-like body 5 includes a dumbbell-shaped member 10 in which spherical bulging portions 10b are formed at both ends of the flange portion 10a, and a connecting member 4B that couples the dumbbell-shaped members 10 to each other. The connecting member 4B is a cylindrical body whose both ends that can accommodate the spherical bulging portion 10b of the dumbbell-shaped member 10 are closed, and a bulging portion insertion opening 4a into which the spherical bulging portion 10b can be inserted is opened at the center.

上記膨隆部挿入開口４ａには、連結部材４Ｂの長手方向に向かってスリット状開口４ｂが開設される。スリット状開口４ｂは、上記亜鈴状部材１０の杆部１０ａが挿通可能な幅寸法を有しており、図４（ｂ）の左側に示すように、亜鈴状部材１０の杆部１０ａが水平姿勢を取ることができる位置まで延設される。   A slit-like opening 4b is opened in the bulging portion insertion opening 4a in the longitudinal direction of the connecting member 4B. The slit-shaped opening 4b has a width dimension through which the flange 10a of the dumbbell-shaped member 10 can be inserted. As shown on the left side of FIG. 4B, the flange 10a of the dumbbell-shaped member 10 is in a horizontal posture. It extends to the position where it can be taken.

紐状体５は、先ず、亜鈴状部材１０の球状膨隆部１０ｂを連結部材４Ｂの膨隆部挿入開口４ａから挿入した後、連結部材４Ｂの終端側に引いて球状膨隆部１０ｂをスリット状開口４ｂに対応させる。球状膨隆部１０ｂのスリット状開口４ｂへの挿通は不能であるために、この状態で亜鈴状部材１０は連結部材４Ｂに脱離不能に連結される。   First, the string-like body 5 is inserted into the bulging portion 10b of the dumbbell-shaped member 10 from the bulging portion insertion opening 4a of the connecting member 4B, and then pulled toward the terminal end side of the connecting member 4B so that the spherical bulging portion 10b is formed into the slit-shaped opening 4b. To correspond to. Since the spherical bulging portion 10b cannot be inserted into the slit-shaped opening 4b, the dumbbell-shaped member 10 is detachably connected to the connecting member 4B in this state.

また同時に、杆部１０ａが挿通自在なスリット状開口４ｂは、図４（ｂ）の右側に示すように、亜鈴状部材１０と連結部材４Ｂとの相対回転のためのスペースを提供する。   At the same time, the slit-shaped opening 4b through which the flange portion 10a can be inserted provides a space for relative rotation between the dumbbell-shaped member 10 and the connecting member 4B, as shown on the right side of FIG.

このようにして連結部材４Ｂを介して亜鈴状部材１０を順次連結すると、連結部において屈曲可能な紐状体５が構成され、連結部材４Ｂが太径の被係止部４に、亜鈴状部材１０の杆部１０ａが細径部７となる。   When the dumbbell-shaped members 10 are sequentially coupled through the coupling member 4B in this way, the string-like body 5 that can be bent at the coupling portion is formed, and the coupling member 4B is formed into the large-diameter locked portion 4 and the dumbbell-shaped member. Ten flange portions 10 a become the small diameter portion 7.
