本発明は、分電盤や制御盤等を構成する箱体の内面で扉を開閉自在に軸支した盤用ボックスに関する。
【０００２】
【従来の技術】
この種の盤用ボックスとして図８に示すものが存在する。このものは、箱体１の各側板５，７の内面を内方奥側に折曲して凹所８を形成し、この凹所８内で扉２を開閉自在に軸支して扉２の外面２ａと箱体１の前面１ａとが略面一になるようにしたものである。つまり、箱体１の対向する２つの側板５（１つしか図示せず）に扉２を軸支する軸受孔３０を形成するとともに扉２に軸部３１を形成して、軸部３１を軸受孔３０で軸支することにより扉２を箱体１に開閉自在に軸支する。
【０００３】
扉２の回動範囲は、箱体１の開口を閉じた位置（図示せず）と、図８に示すように、扉２を開いて扉２の外面２ａが箱体１の一側板７に当接する位置との間で規制される。
【０００４】
【発明が解決しようとする課題】
上述した盤用ボックスにあっては、扉を開いたときに扉の外面が箱体の一側板に当接する構成となっているため、扉の外面や箱体の一側板の塗装が剥げて錆び易くなるという問題があった。
【０００５】
本発明は、かかる事由に鑑みて成されたものであり、その目的とするところは、扉や箱体の塗装が剥げにくく、もって錆びにくい盤用ボックスを提供することにある。
【０００６】
【課題を解決するための手段】
かかる課題を解決するために、請求項１記載の盤用ボックスは、底板及び四周側板により一面に開口を有する形状に形成され、前記四周側板のうちの対向する一対の側板の一方に軸受孔を形成するとともに前記一対の側板の他方に軸受部材を取着した箱体と、前記軸受孔及び前記軸受部材に軸支される一対の軸部を有して前記箱体の開口口縁に開閉自在に取着される扉と、を備えた盤用ボックスにおいて、前記軸部は、前記扉の内面に取着され長孔内で移動自在な調整螺子を移動させることにより前記軸受孔又は前記軸受部材に挿通される軸部材とし、該軸部材のうち前記軸受部材に軸支される軸部材には回動規制突起が形成され、前記軸受部材は、前記扉の最大限開位置でのみ前記回動規制突起が挿通可能な位置に形成された切欠と、この切欠に連通したものであって前記回動規制突起が臨んで前記扉の最大開位置を閉位置から９０度に規制して前記扉がそれ以上開いて前記箱体の一側板に当接しないように前記扉の最大限開位置を規制する回動規制溝とが形成されている。
【０００７】
【発明の実施の形態】
以下、本発明の一実施の形態を図１乃至図７に基づいて説明する。本発明の盤用ボックスは、図２に示すように、底板（図示せず）及び四周側板４，５，６，７により一面に開口を有する形状に形成された箱体１と、この箱体１の開口口縁で箱体１内面の対向する一対の側板４，５間に開閉自在に軸支されて箱体１の開口を塞ぐ外扉２（扉）と、この外扉２の内側で外扉２同様、箱体１の対向する一対の側板４，５間に開閉自在に軸支される内扉３とを備えている。
【０００８】
箱体１は、一枚の鉄板を折曲して四周側板４，５，６，７を形成するとともに、他の一枚の鉄板を四周側板４，５，６，７間に取着して底板を形成している。四周側板４，５，６，７は、それぞれ図２に示す如く、内面を内方奥側に折曲して凹所８を形成し、この凹所８内で外扉２を開閉自在に軸支している。また、四周側板４，５，６，７は、さらに内面を内方奥側に折曲して内扉３も軸支している。この箱体１内には、主幹開閉器９や分岐開閉器１０等の電気機器が配設される。
【０００９】
一対の側板４，５には、図１及び図３に示すように、後述する外扉２の軸部２２，２３を軸支する軸受孔１１，１２が形成されており、外扉２を開閉自在に軸支する。一方の軸受孔１１は、円状に形成されて円柱状の軸部２２が軸支される。他方の軸受孔１２は、略楕円状に形成されて軸部２３を軸支する軸受部材１３が装着される。軸受部材１３は、内部空洞で一部に切欠１４ａを有した軸部差込部１４、この軸部差込部１４に連設されて軸受孔１２内に差し込まれる回動規制部１５とを有し、後述する軸部２３の回動規制突起２４を切欠１４ａに合わせて軸部２３を回動規制部１５方向へ落とし込むことができるようになっている。回動規制部１５には、回動規制突起２４の回動範囲を略９０度に規制する回動規制溝１５ａが形成されており、外扉２の最大開位置を閉位置から略９０度として外扉２の外面２ａが箱体１の一側板７に当接しないように規制する。
【００１０】
外扉２は、箱体１の四周側板４，５，６，７同様、一枚の鉄板を折曲して形成され、図１に示すように、箱体１の開口口縁で箱体１内面の対向する一対の側板４，５間に開閉自在に軸支される。外扉２の側板７側の上下には上述した軸受孔１１又は軸受部材１３とで軸支点を構成する軸部２２，２３を有した軸部材１６，１７が取着されており、外扉２を箱体１内面で開閉自在に軸支する。外扉２の側板６側の略中央には箱体１の側板６に係合して外扉２を閉じた状態に施錠する鎖錠部材１８が取着されており、鎖錠部材１８を操作することにより外扉２を閉じた状態に保持したり外扉２を開いたりすることができるようになっている。
【００１１】
軸部材１６，１７は、図２に示すように、それぞれ外扉２の内面に螺子１９により取着され、長孔２０内で移動自在な調整螺子２１を移動させることにより軸部２２，２３が軸受孔１１又は軸受部材１３に挿通されて外扉２が箱体１内面で軸支されることとなる。この軸部材１６，１７の基本的構造は、特願平７─７０１８４号と同様であり、詳しい説明は省略する。軸部材１７の軸部２３には、上述したように、回動規制溝１５内で回動範囲を略９０度の範囲で規制する回動規制突起２４が形成されている。この軸部材１７と軸受孔１２内に装着される軸受部材１３とで、外扉２を最大限開いた位置を外扉２の外面２ａが箱体１の一側板７に当接しないように規制する規制手段を構成している。
【００１２】
この外扉２を箱体１に軸支するには、外扉２を箱体１の前面１ａに対して略９０度ずらして軸部材１６の軸部２２を軸受孔１１に挿通するとともに、軸部２３の回動規制突起２４を切欠１４ａに合わせ（図６及び図７参照）て軸部２３を軸受孔１２に装着された軸受部材１３に挿通して行う。
【００１３】
内扉３は、図示しないが外扉２同様、側板７側で対向する一対の側板４，５間に開閉自在に軸支されるとともに側板６側で箱体１内部に収納される電気機器配設用フレーム（図示せず）に螺子２５により閉じた状態で螺子止めされる。この内扉３には主幹開閉器９や分岐開閉器１０のハンドル操作用の窓孔２６，２７が形成され、内扉３を閉じた状態で各ハンドルを操作することができるようになっている。また、各分岐開閉器１０に対応する位置にはネームプレート２８が取着されており、分岐開閉器１０による分岐回路が一目瞭然に分かるようになっている。
【００１４】
次に、本実施の形態における軸部材１７及び軸受部材１３による外扉２の最大開位置の規制方法を図４乃至図７に基づいて説明する。この実施の形態によれば、図４及び図５に示すように、外扉２を閉じた状態では従来例同様、外扉２の外面２ａと箱体１の前面１ａとが略面一になっている。このとき、軸部２３の回動規制突起２４は、図５に示すように、軸受部材１３の回動規制溝１５ａ内で横向きに位置している。外扉２を開くと、図７に示すように、軸部２３の回動規制突起２４が軸受部材１３の回動規制溝１５ａ内で移動して回動規制突起２４が回動規制溝１５ａの端面に当接する。従って、図６に示すように、外扉２がそれ以上開いて外扉２の外面２ａが箱体１の一側板７に当接しないように外扉２の最大限開位置を規制することとなり、外扉２の外面や箱体１の一側板７の塗装が剥がれにくいものとなった錆びにくいものとなるのである。
【００１５】
なお、内扉も外扉同様、内扉の最大限開いた位置を内扉の外面が箱体の一側板に当接しないように規制する等、箱体に開閉自在に軸支される扉であれば本実施の形態の軸部材と軸受部材とを使用できる。
【００１６】
また、本実施の形態によれば、外扉の最大限開いた位置を閉じた位置より略９０度として、外扉自身の重量が加わって外扉が箱体の一側板方向に橈んでも外扉の外面が箱体の一側板に当接しない位置までに規制できるよう余裕を持たせているのである。
【００１７】
【発明の効果】
請求項１記載の盤用ボックスによれば、底板及び四周側板により一面に開口を有する形状に形成され、前記四周側板のうちの対向する一対の側板の一方に軸受孔を形成するとともに前記一対の側板の他方に軸受部材を取着した箱体と、前記軸受孔及び前記軸受部材に軸支される一対の軸部を有して前記箱体の開口口縁に開閉自在に取着される扉と、を備えた盤用ボックスにおいて、前記軸部は、前記扉の内面に取着され長孔内で移動自在な調整螺子を移動させることにより前記軸受孔又は前記軸受部材に挿通される軸部材とし、該軸部材のうち前記軸受部材に軸支される軸部材には回動規制突起が形成され、前記軸受部材は、前記扉の最大限開位置でのみ前記回動規制突起が挿通可能な位置に形成された切欠と、この切欠に連通したものであって前記回動規制突起が臨んで前記扉の最大開位置を閉位置から９０度に規制して前記扉がそれ以上開いて前記箱体の一側板に当接しないように前記扉の最大限開位置を規制する回動規制溝とが形成されたので、扉を開いたときに扉の外面が箱体の一側板に当接しない構成となり、扉や箱体の塗装が剥げにくく、もって錆びにくいものとなるという効果を奏する。

BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 2, a box for a board according to the present invention has a box 1 formed by a bottom plate (not shown) and four peripheral side plates 4, 5, 6, 7 so as to have an opening on one surface, and An outer door 2 (door) which is openably and closably supported between a pair of opposing side plates 4 and 5 on the inner surface of the box 1 at the opening edge of the box 1 to close the opening of the box 1, and inside the outer door 2. Like the outer door 2, an inner door 3 is supported between the pair of opposed side plates 4 and 5 of the box 1 so as to be freely opened and closed.
[0008]
The box 1 is formed by bending one iron plate to form four circumferential side plates 4, 5, 6, and 7, and attaching another iron plate between the four circumferential side plates 4, 5, 6, and 7. A bottom plate is formed. As shown in FIG. 2, the four peripheral side plates 4, 5, 6, and 7 each have an inner surface bent inward to form a concave portion 8, and the outer door 2 is pivotally opened and closed in the concave portion 8. It supports. The inner peripheral surfaces of the four peripheral side plates 4, 5, 6, and 7 are further bent inward to the inner side, and the inner door 3 is also pivotally supported. In the box 1, electric devices such as a main switch 9 and a branch switch 10 are arranged.
[0009]
As shown in FIGS. 1 and 3, bearing holes 11, 12 that support shaft portions 22, 23 of the outer door 2, which will be described later, are formed in the pair of side plates 4, 5. Support freely. One bearing hole 11 is formed in a circular shape, and a columnar shaft portion 22 is pivotally supported. The other bearing hole 12 is formed with a substantially elliptical bearing member 13 for supporting the shaft portion 23. The bearing member 13 has a shaft insertion portion 14 having a cutout 14 a in an internal cavity, and a rotation restricting portion 15 connected to the shaft insertion portion 14 and inserted into the bearing hole 12. Then, the shaft 23 can be dropped in the direction of the rotation restricting portion 15 by aligning the rotation restricting projection 24 of the shaft 23 described later with the notch 14a. The rotation restricting portion 15 is formed with a rotation restricting groove 15a that restricts the rotation range of the rotation restricting projection 24 to approximately 90 degrees, and sets the maximum open position of the outer door 2 to approximately 90 degrees from the closed position. The outer surface 2a of the outer door 2 is restricted so as not to contact the one side plate 7 of the box 1.
[0010]
The outer door 2 is formed by bending a single iron plate, similarly to the four peripheral side plates 4, 5, 6, and 7 of the box 1, and as shown in FIG. An inner surface is pivotally supported between a pair of side plates 4 and 5 facing each other so as to be freely opened and closed. Shaft members 16 and 17 having shaft portions 22 and 23 which form a shaft fulcrum with the above-described bearing hole 11 or bearing member 13 are attached to the upper and lower sides of the side plate 7 side of the outer door 2. Are supported on the inner surface of the box 1 so as to be freely opened and closed. A locking member 18 that engages with the side plate 6 of the box body 1 and locks the outer door 2 in a closed state is attached to substantially the center of the outer door 2 on the side plate 6 side, and the locking member 18 is operated. By doing so, the outer door 2 can be kept closed or the outer door 2 can be opened.
[0011]
As shown in FIG. 2, the shaft members 16 and 17 are attached to the inner surface of the outer door 2 by screws 19, respectively, and the shaft portions 22 and 23 are moved by moving a movable adjusting screw 21 in the elongated hole 20. The outer door 2 is inserted through the bearing hole 11 or the bearing member 13 to be supported on the inner surface of the box 1. The basic structure of the shaft members 16, 17 is the same as that of Japanese Patent Application No. 7-70184, and a detailed description is omitted. As described above, the shaft portion 23 of the shaft member 17 is formed with the rotation restricting protrusion 24 for restricting the rotation range within the rotation restricting groove 15 within a range of approximately 90 degrees. The shaft member 17 and the bearing member 13 mounted in the bearing hole 12 regulate the position where the outer door 2 is maximally opened so that the outer surface 2 a of the outer door 2 does not contact the one side plate 7 of the box 1. This constitutes a restricting means.
[0012]
In order to pivot the outer door 2 on the box 1, the outer door 2 is shifted by approximately 90 degrees with respect to the front surface 1 a of the box 1, and the shaft portion 22 of the shaft member 16 is inserted into the bearing hole 11. The rotation control protrusion 24 of the portion 23 is aligned with the notch 14 a (see FIGS. 6 and 7), and the shaft portion 23 is inserted through the bearing member 13 mounted in the bearing hole 12.
[0013]
Although not shown, the inner door 3 is, like the outer door 2, electrically connected to a pair of opposed side plates 4, 5 on the side plate 7 side so as to be openable and closable and housed inside the box 1 on the side plate 6 side. It is screwed to a setting frame (not shown) with the screw 25 closed. The inner door 3 is provided with window holes 26 and 27 for operating handles of the main switch 9 and the branch switch 10, so that each handle can be operated with the inner door 3 closed. . In addition, a name plate 28 is attached to a position corresponding to each branch switch 10, so that the branch circuit formed by the branch switch 10 can be easily understood.
[0014]
Next, a method of restricting the maximum opening position of the outer door 2 by the shaft member 17 and the bearing member 13 in the present embodiment will be described with reference to FIGS. According to this embodiment, as shown in FIGS. 4 and 5, when the outer door 2 is closed, the outer surface 2a of the outer door 2 and the front surface 1a of the box 1 are substantially flush as in the conventional example. ing. At this time, the rotation restricting projection 24 of the shaft portion 23 is located laterally within the rotation restricting groove 15a of the bearing member 13, as shown in FIG. When the outer door 2 is opened, as shown in FIG. 7, the rotation restricting projection 24 of the shaft 23 moves within the rotation restricting groove 15a of the bearing member 13, and the rotation restricting projection 24 Contact the end face. Therefore, as shown in FIG. 6, the maximum opening position of the outer door 2 is regulated so that the outer door 2 is further opened and the outer surface 2a of the outer door 2 does not contact the one side plate 7 of the box 1. In addition, the coating on the outer surface of the outer door 2 and the one side plate 7 of the box 1 becomes less rusting because the coating is less likely to come off.
[0015]
The inner door, like the outer door, is a door that is openably and closably supported by the box, such as restricting the maximum open position of the inner door so that the outer surface of the inner door does not contact the one side plate of the box. If so, the shaft member and the bearing member of the present embodiment can be used.
[0016]
Further, according to the present embodiment, the maximum open position of the outer door is set to approximately 90 degrees from the closed position, and the weight of the outer door itself is added, so that the outer door is outwardly bent even in the direction of one side plate of the box. A margin is provided so that the outer surface of the door can be restricted to a position where it does not come into contact with one side plate of the box.
[0017]
【The invention's effect】
According to the panel box according to claim 1, the bottom plate and the four peripheral side plates are formed in a shape having an opening on one surface, and a bearing hole is formed in one of a pair of opposed side plates of the four peripheral side plates, and the pair of the peripheral plates are formed. A door having a bearing member attached to the other of the side plates, and a door having the bearing hole and a pair of shafts pivotally supported by the bearing member, the door being openably and closably attached to an opening edge of the box body. And a shaft member inserted into the bearing hole or the bearing member by moving an adjusting screw attached to the inner surface of the door and movable in an elongated hole. A rotation restricting projection is formed on a shaft member of the shaft member that is supported by the bearing member, and the bearing member allows the rotation restricting protrusion to be inserted only at the maximum open position of the door. The notch formed at the position and the one communicating with this notch The rotation restricting projection is facing in maximum opening maximum open position the not to abut against the side plate of the box body said door is regulated to 90 degrees from the closed position opens more doors of the door Te Since the rotation restricting groove that regulates the position is formed, when the door is opened, the outer surface of the door does not come into contact with one side plate of the box, and the paint on the door and the box is hard to peel off and it is hard to rust It has the effect of becoming something.
