LOCK DEVICE WITH EMERGENCY TIME UNLOCKING MECHANISM
PROBLEM TO BE SOLVED: To implement improvement of appearance of a door, easy fitting to the door, and excellent operability.SOLUTION: A lock device R comprises: a housing 1; a lock case 2 that is rotatably held inside the housing 1; a cylinder lock 3 that is held inside the lock case 2 so as to be incapable of rotating; and a solenoid 6 that is electrically connected to an earthquake sensor 8 and includes a plunger 61 arranged so as to be capable of advancing/retreating into/from a shaft insertion hole 12 of the housing 1 and a shaft insertion part 22 of the lock case 2. Normally, locking or unlocking of a door is performed by operation of a key at the cylinder lock 3. When an earthquake occurs, the solenoid 6 automatically releases a locked state of the lock case 2 inside the housing 1, allowing rotation operation at an operation knob part 21 to unlock the door.SELECTED DRAWING: Figure 1
【課題】扉の見栄えの向上、扉への簡易な取り付け、優れた操作性などを実現する。【解決手段】ロック装置Ｒは、ハウジング１、ハウジング１内に回転可能に保持される錠ケース２、錠ケース２内に回転不能に保持されるシリンダ錠３、地震感知装置８に電気的に接続され、プランジャ６１をハウジング１の軸挿通孔１２及び錠ケース２の軸挿通部２２に進退可能に配置されるソレノイド６を備え、通常はシリンダ錠３の鍵の操作により扉を施錠又は解錠し、地震の発生に際して、ソレノイド６によりハウジング１内で錠ケース２のロック状態が自動解除され、操作つまみ部２１の回転操作により扉を解錠する。【選択図】図１
