める。D When unlocking from the indoor side: When the indoor side grip ball 14 is turned, the launcher 29 on the indoor side or the cam plate 22 of the case 28 is rotated (Fig. 2), and the operating piece 22-1 of the cam plate 22 is activated. Projection piece 19 of lunch interlocking plate 19
-1 is pressed to move the launch 18 back from the front surface 20.

このランチ連動板１９の後退にともない、連動板１９の
切欠１９−２に係止されている解錠板２５．２６の作動
片２５−１．２６−１も押される。As the launch interlocking plate 19 moves backward, the operating piece 25-1.26-1 of the unlocking plate 25.26, which is locked in the notch 19-2 of the interlocking plate 19, is also pushed.

この結果解錠板２５，２６がケース２８の中空軸２７を
中心として回動し、解錠板２５．２６に挿通された平板
状の解錠棒７が回転する。As a result, the unlocking plates 25 and 26 rotate about the hollow shaft 27 of the case 28, and the flat unlocking rod 7 inserted through the unlocking plates 25 and 26 rotates.

解錠棒７が回転すると、その先端のクラッチ８がクラッ
チ受１２と噛合しているので、回転筒４もばね１１に抗
し、回転させられる。When the unlocking rod 7 rotates, since the clutch 8 at the tip thereof is engaged with the clutch receiver 12, the rotary cylinder 4 is also rotated against the spring 11.

すると回転筒４の係止部４−２がクランプ突片１０−１
より外れ、クランプ１０は解錠棒７とともにばね１１の
伸長力により回転筒４内を後退する。Then, the locking portion 4-2 of the rotary cylinder 4 engages the clamp protrusion 10-1.
When the clamp 10 is released, the clamp 10 moves back inside the rotary cylinder 4 together with the unlocking rod 7 due to the tension of the spring 11.

しめる。a. When unlocking the door from outside in an emergency: 1. Place a coin or the like in the groove 6 of the unlocking piece 5 and turn the unlocking piece 5. By the same action as described above, the rotary cylinder 4 rotates, and its locking portion 4-2 is disengaged from the clamp protrusion 10-1, and the clamp 10 sliding together with the unlocking rod 7 is returned to the unlocking position.

第４図において５−１は解錠片５と回転筒４との連結筒
体である。In FIG. 4, reference numeral 5-1 is a connecting cylinder between the unlocking piece 5 and the rotary cylinder 4.

■ 開扉時誤って押ボタン１５を操作し、施錠状態の１
＼閉扉した場合：開扉時誤って押ボタン１５を押し、施錠状態のま＼閉扉
したとする。■ When opening the door, you accidentally operated the pushbutton 15 and the locked door opened.
When the door is closed: Suppose that when the door was opened, the pushbutton 15 was pressed by mistake, and the door was closed while it was still locked.

このように施錠状態の１＼閉扉すると、ランチ１８は一
旦受部材にぶつかりケース２８内に後退する。When the door is closed in the locked state as described above, the launch 18 once hits the receiving member and retreats into the case 28.

このときランチの連動板１９の切欠１９−２に解錠板２
５，２６０作動片２５−１．２６−１が係止されている
。At this time, the unlocking plate 2 is inserted into the notch 19-2 of the lunch interlocking plate 19.
5,260 actuating piece 25-1.26-1 is locked.

したがってランチ連動板１９の後退とともに、解錠板２
５，２６も回動し、解錠板２５．２６に挿通された解錠
枠７が回転する。Therefore, as the launch interlocking plate 19 retreats, the unlocking plate 2
5 and 26 also rotate, and the unlocking frame 7 inserted through the unlocking plates 25 and 26 rotates.

この結果、解錠枠７先端のクラッチ８が回転筒４を回転
