A slider incorporated so as to move up and down via an appropriate transmission mechanism, a vertically long opening provided in at least the opening direction side corner of the indoor surface of the outer lock box and the outdoor door, and both end portions vertically positioned in this opening are vertically moved. A lock rod that is slidably inserted into the slider and has both ends rotatably attached to the slider, and a spring that provides the lock rod with return rotatability overlapping the inner surface of the outer lock box. In addition to the outdoor lock composed of the internal lock box, the inner lock box that is attached to the combination part of the indoor door, and the inner lock box that is rotatably incorporated through a vertical support shaft, the outdoor lock has a return rotatability in the opening direction. Of the given rotating body and the above Outdoor surface of the box A window provided so that the locking rod is fitted from the opening side corner of the outdoor door to the closing direction side corner, and the tip of the locking rod inside the inner lock box immediately before the closing of the outdoor door. A magnet for attraction provided to be fitted into the window, a notch provided so that the tip of the locking rod fitted to the window is fitted inward from the outer peripheral surface of the rotating body, and the inside of the inner lock box. An automatic locking device provided to prevent rotation of the rotary body that has been rotated by the engagement of the notch and the lock rod in the return direction, and a locking of the automatic locking device on the indoor side of the inner lock box. The lock is composed of an operating device provided to release the lock and an indoor lock made up of an interlocking device provided to release the locking of the automatic locking device when the slider slides.

【０００７】[0007]

【作用】屋外戸の開放時には、バネによる復帰力により
外錠箱の屋内壁表面に錠杆が重なり合っている。When the outdoor door is opened, the lock rod overlaps the surface of the inner wall of the outer lock box due to the restoring force of the spring.

【０００８】閉鎖方向に屋外戸をスライドすると、閉鎖
終了前に磁石により錠杆の先を磁吸するので、屋内戸の
方向に先が突出するよう復帰力に抗して錠杆が回動す
る。When the outdoor door is slid in the closing direction, the tip of the locking rod is magnetically attracted by the magnet before the closing is completed. Therefore, the locking rod is rotated against the restoring force so that the leading end projects toward the indoor door. .

【０００９】上記回動した錠杆の先は、窓から内錠箱に
嵌入すると共に、切欠きの開口に合致するため、屋外戸
の閉鎖方向のスライドにより切欠きに錠杆の先が嵌入す
る。Since the tip of the pivoted locking rod is fitted into the inner lock box through the window and coincides with the opening of the notch, the tip of the locking rod is fitted into the notch by sliding in the closing direction of the outdoor door. .

【００１０】切欠きに錠杆の先が嵌入すると、錠杆を介
し復帰力に抗して回転体を回転させる。When the tip of the lock rod is fitted into the notch, the rotating body is rotated against the restoring force through the lock rod.

【００１１】このとき、操作装置を操作して自動係止装
置による回転体の復帰方向の回動阻止を解除しておく
と、回転体の復帰方向の回転阻止がないため、閉鎖後の
屋外戸を開放方向にスライドさせることができる。At this time, if the operation device is operated to release the rotation blocking of the rotating body in the returning direction by the automatic locking device, the rotation of the rotating body in the returning direction is not blocked, so that the outdoor door after closing is closed. Can be slid in the opening direction.
