    • A lock mechanism for releasably locking a security bar (14) over an opening (12) through a wall (10) includes a housing (30, 32, 60) for mounting to the wall adjacent the opening. An engagement mechanism (28) is coupled to the security bar (14). A keeper member (26) in the housing is movable to selectively engage a lock surface (102) on the engagement mechanism to restrain the engagement mechanism from movement relative to the housing; the engagement mechanism being allowed to move unrestrained relative to the housing when the keeper member does not engage the lock surface. A manually-operable latch mechanism (24) in the housing moves the keeper member out of engagement with the lock surface. A receiver tube (70) forms a passage between the housing and the outside surface of the wall, with the engagement mechanism (28) extending through the receiver tube without engaging the receiver tube so that the engagement mechanism and security bar are laterally moveable due to settling of the structure of which the wall is a part. An optional slide mechanism (22) is operable by an external operator (120), such as a thermal sensor, smoke detector or wireless receiver, to operate the latch mechanism (24).
    • 用于通过壁(10)可释放地将安全杆(14)锁定在开口(12)上方的锁定机构包括用于安装到邻近开口的壁的壳体(30,32,60)。 接合机构(28)联接到安全杆(14)。 壳体中的保持构件(26)可移动以选择性地接合接合机构上的锁定表面(102),以限制接合机构相对于壳体的移动; 当保持器构件不接合锁定表面时,允许接合机构相对于壳体无限制地移动。 壳体中的可手动操作的闩锁机构(24)使保持器构件脱离与锁定表面的接合。 接收管(70)在壳体和壁的外表面之间形成通道,其中接合机构(28)延伸穿过接收管而不与接收管接合,使得接合机构和安全杆由于 安置墙的一部分的结构。 可选的滑动机构(22)可由诸如热传感器,烟雾探测器或无线接收器的外部操作器(120)操作,以操作闩锁机构(24)。
