嵌挿することによって 可動片１の自由端は固着片１０
の一端に枢着される。By fitting the shaft tubes 7 and 8 between the upper and lower horizontal pieces 11 and 12, and fitting the second pivot 15 into these shaft tubes and the shaft holes 13 and 14, the free end of the movable piece 1 becomes a fixed piece. 10
It is pivoted to one end of the .
可動片１の自由端には、前記軸筒７，８の間の部分を延
長することによって制止片１６が設けられ、コ字状可動
片１の連結板部分１ａと平行に突設された制止片１６は
、その基端部が第２枢軸１５を抱持するように若干量げ
られ、その背面１６ｂは第２枢軸１５に添接されている
。A restraining piece 16 is provided at the free end of the movable piece 1 by extending the portion between the shaft tubes 7 and 8, and a restraining piece 16 is provided that protrudes parallel to the connecting plate portion 1a of the U-shaped movable piece 1. The piece 16 is slightly weighted so that its proximal end part embraces the second pivot shaft 15, and its back surface 16b is attached to the second pivot shaft 15.
制止片１６は前記軸筒７．８よりも大きく突出し、その
先端部の正面１６ ａは固着片１０の背面１０ ｂに当
接自在である。The stopper piece 16 protrudes more than the shaft cylinder 7.8, and its front end 16a can freely come into contact with the back side 10b of the fixing piece 10.
第１枢軸６と第２枢軸１５は平行に配置され、第１枢軸
６には前記軸筒４，５の間の部分にコイルばね１７が嵌
装されている。The first pivot shaft 6 and the second pivot shaft 15 are arranged in parallel, and a coil spring 17 is fitted in the first pivot shaft 6 at a portion between the shaft tubes 4 and 5.
このばね１７は、箱本体１８から飛び出る方向に可動片
１を回転付勢している。This spring 17 rotationally urges the movable piece 1 in the direction of protruding from the box body 18.
この裏蝶番では、扉９を閉鎖した時には前記固着片１０
は制止片１６の正面１６ ａに当接し、コイルばね１７
は最大限に巻き締められている。With this back hinge, when the door 9 is closed, the fixed piece 10
is in contact with the front surface 16a of the stopper piece 16, and the coil spring 17
is wrapped as tightly as possible.
そのため、扉９の反対側に設けた掛金装置を外すと、扉
９は前記ばね１７の弾撥力によって開放駆動され、可動
片１は第１枢軸６を中心にして第３の矢印方向に回動す
る。Therefore, when the latch device provided on the opposite side of the door 9 is removed, the door 9 is driven open by the elastic force of the spring 17, and the movable piece 1 rotates in the direction of the third arrow about the first pivot 6. move.
第４図の位置まで扉９を開放操作１２から、第２枢軸１
５を中心にして矢印の方向に回動させると、扉９は第５
図に示したように１８０°開放され、箱本体１８の正面
と平行に配置される。From the opening operation 12 of the door 9 to the position shown in Fig. 4, the second pivot 1
When the door 9 is rotated in the direction of the arrow with 5 as the center, the 5th door
As shown in the figure, it is opened 180 degrees and is arranged parallel to the front of the box body 18.
以上のように本考案の裏蝶番は、第１枢軸６によって基
端が箱本体１８に枢着されるＵ字状の可動片１と、扉９
の背面に取付けられる固着片１０とから成り、第１枢軸
６と平行な第２枢軸１５によって可動片１の自由端を固
着片１の一端に枢着したものであるから、扉９は１８０
°まで完全に開放されるのである。As described above, the back hinge of the present invention includes the U-shaped movable piece 1 whose base end is pivoted to the box body 18 by the first pivot 6, and the door 9.
The free end of the movable piece 1 is pivoted to one end of the fixed piece 1 by a second pivot 15 parallel to the first pivot 6, so the door 9 has a length of 180 mm.
It is completely opened up to 50°.
更に、本考案では、可動片１の自由端の一部が延長され
て制止片１６となり、制止片１６の正面１６ ａには前
記固着片１０の背面１０ ｂが当接自在であるため、第
５図のように広く開放した扉９が何らかの原因で閉鎖方
向に第２枢軸１５を中心に回動したとしても、この回動
は、扉９に取付けた固着片１０が制止片１６に衝接した
段階で阻止され、扉の開放状態は的確に維持されるので
ある。Furthermore, in the present invention, a part of the free end of the movable piece 1 is extended to become the stopper piece 16, and the back face 10b of the fixed piece 10 can freely come into contact with the front face 16a of the stopper piece 16. Even if the widely opened door 9 rotates about the second pivot 15 in the closing direction for some reason as shown in FIG. This prevents the door from opening at this stage, and keeps the door open.
即ち、本考案の裏蝶番は、扉を開いて箱本体の内蔵機器
の点検調整等といった各種の作業を行なうことが多い、
配電盤収納用キャビネット等に用いるのに適した蝶番で
ある。In other words, the back hinge of the present invention is often used to open the door and perform various tasks such as inspecting and adjusting the built-in equipment of the box body.
This hinge is suitable for use in power distribution cabinets, etc.
また、制止片１６は可動片１の自由端部を延長して得ら
れたものであるがら、この裏蝶番は簡単なプレス加工に
よって容易かつ安価に製作される利点がある。Further, although the restraining piece 16 is obtained by extending the free end of the movable piece 1, this back hinge has the advantage that it can be manufactured easily and inexpensively by simple press working.
更に、制止片１６は、別体に製作したものを溶接やリベ
ット止め等によって可動片に連結したものでなく、上記
のように可動片１に一体に形成されたものであると共に
、その背面１６ ｂが第２枢軸１５に添接されているた
め、必要十分な機械的強度を備えており、繰り返し使用
によって脱落したりガタ付くことがなく、寿命の長い製
品が得られるのである。Further, the restraining piece 16 is not manufactured separately and connected to the movable piece by welding, riveting, etc., but is formed integrally with the movable piece 1 as described above. Since b is attached to the second pivot 15, it has sufficient mechanical strength and will not fall off or rattle after repeated use, resulting in a product with a long life.
