ジ軸の軸方向中間部には扉板板面に平行に直径方向のピ
ン６が突設されている。An upper hinge shaft 5 is provided perpendicularly to the upper edge of the door plate 2 at a position facing the lower hinge shaft 3, and an upper hinge shaft 5 is provided in the axially intermediate portion of the upper hinge shaft parallel to the surface of the door plate. A diametrical pin 6 is provided protrudingly.

筐体１の開口縁の上部−側、すなわち、筐体天板の下部
軸受４と対向する側には上部軸受７の固定板８が固着さ
れ、この固定板８の開口縁側の端縁には開口縁に平行な
回動軸９によって上部軸受の可動板１０が可回動に連結
されている。A fixing plate 8 of the upper bearing 7 is fixed to the upper side of the opening edge of the casing 1, that is, the side of the casing top plate facing the lower bearing 4, and the edge of the fixing plate 8 on the opening edge side is A movable plate 10 of the upper bearing is rotatably connected by a rotation shaft 9 parallel to the edge of the opening.

可動板１０には直径両端に位置し上部ヒンジ軸５のピン
６を通過させるに足る切欠１１をそなえた軸孔１．２が
設けられている。The movable plate 10 is provided with shaft holes 1.2 located at both diametrical ends and provided with notches 11 sufficient to allow the pin 6 of the upper hinge shaft 5 to pass through.

また、可動板１０には回動軸９に巻装されたばね１３に

。Further, a spring force is applied to the movable plate 10 in a direction approaching the upper edge of the door plate 2 by a spring 13 wound around the rotation shaft 9.

上記構成の本考案扉は次のように作動する。The door of the present invention having the above structure operates as follows.

まず、平常時は下部軸受４に下部ヒンジ軸３を、また上
部軸受７の可動板１０の軸孔１２に上部ヒンジ軸５をそ
れぞれ支持しており、可動板１０はばね１３によって扉
板２の上縁に圧接されている。First, under normal conditions, the lower hinge shaft 3 is supported by the lower bearing 4, and the upper hinge shaft 5 is supported by the shaft hole 12 of the movable plate 10 of the upper bearing 7, and the movable plate 10 is supported by the spring 13. It is pressed against the upper edge.

従って、扉板２は第２図、第３図に示すように通常の扉
におけると同様自由に開閉することができる１゜ 扉板２を取外す場合には、まず扉板２を第３図に示すよ
うに上部ヒンジ軸５のピン６が可動板１０゛の切欠１１
に整合するまで回動させる。Therefore, as shown in Figures 2 and 3, the door plate 2 can be opened and closed freely like a normal door.When removing the door plate 2, first remove the door plate 2 as shown in Fig. 3. As shown, the pin 6 of the upper hinge shaft 5 is inserted into the notch 11 of the movable plate 10.
Rotate until it aligns with the

この状態になるとミ可動板１０を矢印Ａ方向に動かすこ
とができるので、可動板１０をばね１３に抗して扉板２
の上縁からはなれる方向に回動させ、上部ヒンジ軸５か
ら離脱させる。In this state, the movable plate 10 can be moved in the direction of arrow A, so the movable plate 10 is moved against the spring 13 to move the door plate 2
The upper hinge shaft 5 is rotated in a direction away from the upper edge of the upper hinge shaft 5.

これにより上部ヒンジ軸５は上部軸受７からフリーとな
るので、扉板２を持ち上げて下部ヒンジ軸３を下部軸受
４から引抜き、扉板２を筐体１から取外すことができる
。As a result, the upper hinge shaft 5 becomes free from the upper bearing 7, so the door plate 2 can be lifted, the lower hinge shaft 3 can be pulled out from the lower bearing 4, and the door plate 2 can be removed from the housing 1.

なお、取外した扉板２を再び取付けるには、上部軸受７
の可動板１０を前記の如くばね１３に抗して開いておき
、扉板２の下部ヒンジ軸３を下部軸受４に挿入し、扉板
２の上縁−側を筐体１に近接させ、扉板２を上部ヒンジ
軸５のピン６が可動板１０の切欠１１の位置をとる角度
とし、ここで可動板１０を上部ヒンジ軸５に係合させれ
ばよい。In addition, in order to reinstall the removed door plate 2, the upper bearing 7
The movable plate 10 is opened against the spring 13 as described above, the lower hinge shaft 3 of the door plate 2 is inserted into the lower bearing 4, the upper edge side of the door plate 2 is brought close to the housing 1, The door plate 2 may be set at an angle such that the pin 6 of the upper hinge shaft 5 takes the position of the notch 11 of the movable plate 10, and the movable plate 10 may be engaged with the upper hinge shaft 5 at this point.

上記から明らかなように、本考案によれば上部ヒンジ軸
のピンと上部軸受の可動板１０の軸孔の切欠１１とが整
合しない限り、可動板１０は動くことができないので、
従来のこの種の扉における如く誤りによる意図しない扉
板の取外し、落下等を生じるおそれはない。As is clear from the above, according to the present invention, unless the pin of the upper hinge shaft and the notch 11 of the shaft hole of the movable plate 10 of the upper bearing are aligned, the movable plate 10 cannot move.
Unlike conventional doors of this type, there is no risk of unintentional removal or falling of the door plate due to mistake.

また、本考案は上記実施例のみに限定されない。Furthermore, the present invention is not limited to the above embodiments.

例えば、上部ヒンジ軸に設けるピンは必ずしも直径両端
の延長上にある必要はなく、半径方向の１箇のピンで置
換することができる。For example, the pin provided on the upper hinge shaft does not necessarily have to be on an extension of both diametrical ends, but can be replaced with a single pin in the radial direction.

さらに、ピン６の植立方向も扉板板面に平行に限定され
ない。Furthermore, the direction in which the pins 6 are planted is not limited to being parallel to the surface of the door plate.
