前扉３は、正面視が本体２と略同じ横長矩形状で、周囲の四辺には、後方への折り返し部９が周設されて、下側の折り返し部９の内側で左右方向の中央には、係止片１０が突設されている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view of a residential distribution board 1 showing an example of a distribution board, FIG. 2 is a perspective view, and the front door 3 is in an open position.
The distribution board 1 includes a main body 2 that is horizontally long when viewed from the front, and a front door 3 that opens and closes the front surface of the main body 2. The main body 2 includes a front cover 4 and a rear cover 5, and accommodates a limiter 6, a main breaker 7, a plurality of branch breakers 8, 8,.
The front door 3 has a horizontally long rectangular shape that is substantially the same as the main body 2 as viewed from the front. Around the four sides of the front door 3 is a back turn-up portion 9 that is provided inside the lower turn-up portion 9 in the center in the left-right direction. The locking piece 10 is protrudingly provided.

本体２の前面で前カバー４の上部には、左右一対のヒンジ１１，１１が設けられて、このヒンジ１１，１１を介して前扉３が上端を中心に回転可能に連結されている。
このヒンジ１１は、前カバー４の前面に突設された本体側ヒンジ部１２と、前扉３の裏面から折り返し部９の裏面にかけて突設された扉側ヒンジ部１３とからなる。以下、ヒンジ１１の詳細を説明するが、左右対称であるため、左側のヒンジ１１で説明する。 A pair of left and right hinges 11, 11 are provided on the front surface of the main body 2 and on the upper portion of the front cover 4, and the front door 3 is connected to the hinges 11, 11 so as to be rotatable around the upper end.
The hinge 11 includes a main body side hinge portion 12 projecting from the front surface of the front cover 4 and a door side hinge portion 13 projecting from the back surface of the front door 3 to the back surface of the folded portion 9. Hereinafter, although the detail of the hinge 11 is demonstrated, since it is bilaterally symmetrical, it demonstrates with the hinge 11 on the left side.

まず、本体側ヒンジ部１２は、図３に示すように、左右方向に所定間隔をあけて前方へ突設されたブロック状の受台１４，１４を有し、各受台１４の上面には、扉側ヒンジ部１３の後述する頭付きピン２２を支持する軸受部１５がそれぞれ立設されている。
また、左右の受台１４，１４の間には、受台１４，１４の間に落ち込む下面と、左右の受台１４，１４の相対向する内側面と、奥側の背面とで囲まれて上面及び前面に開口する保持部１６が形成されている。このうち各受台１４の内側面には、上下に所定間隔をおいて形成されたスリット１７，１７により、後端が左右方向へ弾性変形可能な弾性片１８，１８が形成されて、各弾性片１８の相対向する面には、後方へ行くに従って徐々に高くなる係止突起１９がそれぞれ突設されている。この弾性片１８は、保持部１６の背面よりも手前に短く形成されて、図４，５に示すように、保持部１６の背面との間に、後述する板バネ３０の後板部３３が嵌合可能な隙間Ｓを形成している。 First, as shown in FIG. 3, the main body-side hinge portion 12 has block-shaped pedestals 14 and 14 protruding forward with a predetermined interval in the left-right direction. The bearing portions 15 for supporting the headed pins 22 to be described later of the door side hinge portion 13 are respectively provided upright.
In addition, the left and right cradles 14 and 14 are surrounded by a lower surface that falls between the cradles 14 and 14, inner surfaces opposite to each other and the rear surfaces on the far side. A holding portion 16 that opens to the upper surface and the front surface is formed. Among these, elastic pieces 18 and 18 whose rear ends are elastically deformable in the left-right direction are formed on the inner side surface of each cradle 14 by slits 17 and 17 formed at predetermined intervals in the vertical direction. On the opposing surfaces of the pieces 18, locking projections 19 that gradually increase toward the rear are provided. The elastic piece 18 is formed shorter than the back surface of the holding portion 16, and a rear plate portion 33, which will be described later, is disposed between the elastic piece 18 and the back surface of the holding portion 16 as shown in FIGS. A gap S that can be fitted is formed.

次に、扉側ヒンジ部１３は、本体側ヒンジ部１２の軸受部１５，１５の間に納まる左右一対の支持片２０，２０と、両支持片２０，２０の間に嵌合する係合ブロック２１と、支持片２０，２０と係合ブロック２１とを左右方向に貫通する頭付きピン２２とからなる。すなわち、支持片２０，２０を軸受部１５，１５の間に配置して、内側（図３の右側）から頭付きピン２２を、軸受部１５，１５ごと貫通させることで、扉側ヒンジ部１３は軸受部１５，１５へ回転可能に連結される。頭付きピン２２の差込側の受台１４上には、図６，７に示すように、貫通させた頭付きピン２２の抜け方向側に位置するストッパ片２３が突設されている。
係合ブロック２１は、下面から前面に亘る外周面を支持片２０，２０の外側に露出させて、当該外周面には、前扉３の開閉位置で後述する板バネ３０に係合する係合凸部２４が形成されている。 Next, the door-side hinge portion 13 includes a pair of left and right support pieces 20, 20 that fit between the bearing portions 15, 15 of the main body-side hinge portion 12, and an engagement block that fits between the support pieces 20, 20. 21 and a headed pin 22 that penetrates the support pieces 20 and 20 and the engagement block 21 in the left-right direction. That is, by arranging the support pieces 20 and 20 between the bearing portions 15 and 15 and penetrating the headed pin 22 together with the bearing portions 15 and 15 from the inside (the right side in FIG. 3), the door side hinge portion 13. Is rotatably connected to the bearing parts 15, 15. As shown in FIGS. 6 and 7, a stopper piece 23 is provided on the receiving base 14 on the insertion side of the headed pin 22 so as to be located on the side of the penetrating direction of the headed pin 22 penetrated.
The engagement block 21 has an outer peripheral surface extending from the lower surface to the front surface exposed to the outside of the support pieces 20, 20, and the outer peripheral surface engages with a leaf spring 30 described later at the opening / closing position of the front door 3. A convex portion 24 is formed.

そして、本体側ヒンジ部１２の保持部１６には、板バネ３０が設けられている。この板バネ３０は、上板部３１と、下板部３２と、上板部３１と下板部３２との後端間を繋ぐ後板部３３とからなる側面視コ字状で、上板部３１の前端には、係合ブロック２１の係合凸部２４に係合する山形状の係合部３４が形成されている。
この板バネ３０は、左右方向は、受台１４，１４の内側面間に略納まる寸法で形成され、係合部３４を除く上下方向は、保持部１６の底面から上側のスリット１７の上端までの長さよりも大きい寸法で形成されている。 A leaf spring 30 is provided on the holding portion 16 of the main body side hinge portion 12. The leaf spring 30 has a U-shape in a side view including an upper plate portion 31, a lower plate portion 32, and a rear plate portion 33 connecting the rear ends of the upper plate portion 31 and the lower plate portion 32. At the front end of the portion 31, a mountain-shaped engagement portion 34 that engages with the engagement convex portion 24 of the engagement block 21 is formed.
The leaf spring 30 is formed in a dimension that fits substantially between the inner side surfaces of the pedestals 14, 14 in the left-right direction, and from the bottom surface of the holding portion 16 to the upper end of the upper slit 17 in the vertical direction excluding the engaging portion 34. It is formed with a dimension larger than the length of.

以上の如く構成された分電盤１において、本体２に前扉３を取り付ける際には、板バネ３０を取り付けない状態で、本体側ヒンジ部１２の軸受部１５，１５の間に、扉側ヒンジ部１３を挿入して、前述のように頭付きピン２２で連結する。これにより前扉３は本体２の上部へ回転可能に連結される。
次に、前扉３を前方へ跳ね上げた開放位置として、板バネ３０を、係合部３４を手前上側にした後ろ向き姿勢で、後板部３３から受台１４，１４の間へ差し込んで保持部１６に押し込む。すると、後板部３３が左右の係止突起１９，９と干渉して弾性片１８，１８を左右に押し広げながら後退し、隙間Ｓに到達すると、図５及び図８，９に示すように、後板部３３を相対的に越えた弾性片１８，１８が内側に弾性復帰して係止突起１９，１９を後板部３３の両端縁内側に係合させる。よって、板バネ３０は、係止突起１９，１９に抜け止めされた状態で保持部１６に嵌合保持される。 In the distribution board 1 configured as described above, when the front door 3 is attached to the main body 2, the door side is interposed between the bearing portions 15, 15 of the main body side hinge portion 12 without the leaf spring 30 being attached. The hinge portion 13 is inserted and connected with the headed pin 22 as described above. Thereby, the front door 3 is rotatably connected to the upper part of the main body 2.
Next, as the open position where the front door 3 is flipped forward, the leaf spring 30 is inserted and held between the rear plate portion 33 and the cradles 14 and 14 in a rearward posture with the engaging portion 34 facing upward. Push into part 16. Then, the rear plate portion 33 interferes with the left and right locking projections 19 and 9 and moves backward while pushing the elastic pieces 18 and 18 left and right, and when reaching the gap S, as shown in FIGS. Then, the elastic pieces 18 and 18 relatively beyond the rear plate portion 33 are elastically restored inward to engage the locking projections 19 and 19 with the inner sides of both ends of the rear plate portion 33. Therefore, the leaf spring 30 is fitted and held by the holding portion 16 in a state in which the leaf spring 30 is prevented from coming off by the locking protrusions 19 and 19.

このとき係合部３４は、係合ブロック２１の係合凸部２４の後側で外周面を下方から押圧することになるため、前扉３は板バネ３０によって開放位置で保持される。ここから前扉３を閉じると、そのまま係合ブロック２１が板バネ３０の上板部３１を押し下げて弾性変形させ、係合凸部２４を乗り越えさせるため、本体２の前面を覆う閉塞位置まで回転させることができる。閉塞位置では、弾性復帰した上板部３１の係合部３４が係合凸部２４の下側に係合して閉塞位置を保持することになる。本体２の下部には、閉塞位置で前扉３の係止片１０を受け入れて係止させる被係止部２５が設けられている。
なお、板バネ３０を取り外す必要が生じた際には、左右の本体側ヒンジ部１２の保持部１６において、左右の弾性片１８，１８を外側へ押し広げて後板部３３への係止突起１９，１９の係合を解除させれば、そのまま板バネ３０を前方へ引き抜くことができる。 At this time, since the engaging portion 34 presses the outer peripheral surface from below on the rear side of the engaging convex portion 24 of the engaging block 21, the front door 3 is held in the open position by the leaf spring 30. When the front door 3 is closed from here, the engagement block 21 pushes down the upper plate portion 31 of the leaf spring 30 to be elastically deformed and rides over the engagement convex portion 24, so that it rotates to the closed position covering the front surface of the main body 2. Can be made. In the closed position, the engaging portion 34 of the upper plate portion 31 that has been elastically restored engages with the lower side of the engaging convex portion 24 to hold the closed position. A locked portion 25 that receives and locks the locking piece 10 of the front door 3 at the closed position is provided at the lower portion of the main body 2.
When it is necessary to remove the leaf spring 30, the left and right elastic pieces 18, 18 are pushed outward in the holding portion 16 of the left and right body-side hinge portions 12 to lock the rear plate portion 33. If the engagement of 19 and 19 is released, the leaf spring 30 can be pulled out as it is.

このように、上記形態の分電盤１によれば、板バネ３０を、本体側ヒンジ部１２に形成された保持部１６に嵌合して固定しているので、ネジを用いることなくヒンジ１１への板バネ３０の取り付けが可能となる。よって、板バネ３０の取付が簡単となって工程数の削減を図ることができる。
特にここでは、保持部１６には、板バネ３０に弾性係止して保持部１６から抜け止めする弾性片１８が設けられているので、ネジレスであっても板バネ３０を脱落のおそれなく確実に固定することができる。 Thus, according to the distribution board 1 of the said form, since the leaf | plate spring 30 is fitted and fixed to the holding | maintenance part 16 formed in the main body side hinge part 12, it is hinge 11 without using a screw | thread. The leaf spring 30 can be attached to the head. Therefore, the attachment of the leaf spring 30 is simplified, and the number of processes can be reduced.
In particular, here, the holding portion 16 is provided with an elastic piece 18 that is elastically locked to the leaf spring 30 to prevent it from coming off from the holding portion 16, so that even if it is screwless, the leaf spring 30 can be securely removed without fear of dropping off. Can be fixed to.

なお、板バネの形状や弾性片の形状、本体側ヒンジ部や扉側ヒンジ部の形状は上記形態に限らず、例えば板バネをコ字状でなくＣ字状等としたり、弾性片の幅や厚みを変更したり、扉側ヒンジ部に頭付きピンに代わる軸部を一体に設けたり等適宜設計変更可能である。また、ヒンジ部間で軸受部と頭付きピン又は軸部との関係を逆にしても差し支えない。
さらに、上記形態では、本体側ヒンジ部に弾性片を設けて板バネに係止させているが、板バネに弾性片を設けて本体側ヒンジ部に設けた凹部等に弾性係止させることで抜け止めを図ってもよい。
但し、弾性片は必須ではなく、保持部の入口に板バネを抜け止めするストッパを設けたり、保持部の入口を狭くしたりすることで板バネの嵌合保持を図ることは可能である。 The shape of the leaf spring, the shape of the elastic piece, and the shape of the main body side hinge part and the door side hinge part are not limited to the above-mentioned forms. For example, the leaf spring is not C-shaped but C-shaped, or the width of the elastic piece. The design can be changed as appropriate, for example, by changing the thickness or changing the thickness of the door-side hinge or integrally providing a shaft portion instead of the headed pin. Further, the relationship between the bearing portion and the headed pin or shaft portion may be reversed between the hinge portions.
Furthermore, in the above embodiment, an elastic piece is provided on the body-side hinge portion and locked to the leaf spring, but an elastic piece is provided on the leaf spring and elastically locked to a recess provided on the body-side hinge portion. You may try to prevent it from coming off.
However, the elastic piece is not indispensable, and it is possible to fit and hold the leaf spring by providing a stopper for preventing the leaf spring from coming off at the inlet of the holding portion or by narrowing the inlet of the holding portion.

そして、上記形態では、本体側ヒンジ部に板バネを設けて扉側ヒンジ部に係合させているが、これと逆に、扉側ヒンジ部に板バネを設けて本体側ヒンジ部に係合させてもよい。すなわち、扉側ヒンジ部において板バネを嵌合固定させることは可能である。
その他、ヒンジの数も増減可能であるし、ヒンジの位置も、本体の上部に限らず、下部や側部等であっても本発明の適用は妨げない。 And in the said form, although the leaf | plate spring was provided in the main body side hinge part and engaged with the door side hinge part, conversely, the leaf | plate spring was provided in the door side hinge part and engaged with the main body side hinge part. You may let them. That is, it is possible to fit and fix the leaf spring at the door side hinge.
In addition, the number of hinges can be increased and decreased, and the position of the hinge is not limited to the upper part of the main body, and application of the present invention is not hindered even at the lower part or the side part.
