PROBLEM TO BE SOLVED: To provide a door-locking mechanism of a simple structure, good in both locking and unlocking operability.SOLUTION: The door-locking mechanism works as follows: when the door-locking mechanism 1 is in a locked condition, the finger or the like of a relevant user is hooked on a hook 42a followed by pulling in the direction of arrow A (forward), thereby the hook 42a is turned to a turning position shown in Fig.8 (and not shown here) around a rotating axis 39 in the direction of the arrow A thereby, a locking part 42b is located out of a housing space 102, enabling the frame material 110 of a front grid frame 14 to be moved from the housing space 102 into the outside simultaneously, in the condition shown in Fig.8 (and not shown here), a locking part 42c is located out of a housing space 112, enabling the frame material 110 of a front grid frame 14 to be moved from a housing space 112 into the outside that is, the locking parts 42b and 42c are unlocked.COPYRIGHT: (C)2011,JPO&INPIT【課題】 旋錠および解錠の操作性がよく、簡単な構造のの扉施錠装置を提供する。【解決手段】 扉施錠装置1が旋錠状態であるときに、ユーザは、指等を手掛け部42aに引っ掛けて矢印Aの向き(手前)に引っ張ることで、手掛け部42aが回転軸39を中心に矢印Aの向きに図8に示す回転位置まで回転する。これにより、ロック部42bが収容領域102の外に位置し、正面格子枠14の枠材110が収容領域102から外に移動可能になる。同時に、図8の状態において、ロック部42cが収容領域112の外に位置し、正面格子枠14の枠材110が収容領域112から外に移動可能になる。すなわちロック部42b,42cのロック状態が解除される。【選択図】 図2
