    • A locking mechanism selectively engages and isolates an external handle of a vault door from both a bolt and a pair of locks which control the condition of the door. The mechanism includes a slide vertically movable between first and second positions in response to the conditions of the locks. The slide incorporates a pin at its lower end. The handle is mounted on a shaft that extends through the door and terminates on the interior side in a hub. A housing mounted for rotation on the interior side of the door incorporates an inverter "T-shaped" guide slot which accepts the pin. When the pin is in the vertical leg of the "T-shaped" slot, rotation of the housing is inhibited. A probe is mounted for movement on the housing and is biased toward the hub. The probe is attached to a yoke which engages the pin such that when the pin is in the first position the probe is retracted from the hub. When the pin is in the second position the probe engages the hub, which causes the hub and housing to move together in response to rotation of the handle. The housing is connected to the bolt of the vault door which moves between the latched and unlatched conditions in response to movement of the housing.
    • 锁定机构选择性地将保险库门的外部手柄与锁定门锁的两个锁相配合并隔离。 该机构包括响应于锁的条件在第一位置和第二位置之间垂直移动的滑块。 滑块在其下端包含一个销。 手柄安装在延伸穿过门并且终止于轮毂内侧的轴上。 安装在门内侧旋转的外壳包括一个接收销钉的逆变器“T形”导槽。 当销在“T形”槽的垂直支腿中时,外壳的旋转被禁止。 安装探针以在壳体上移动并朝向轮毂偏置。 探针附接到与销接合的轭,使得当销处于第一位置时,探针从轮毂缩回。 当销处于第二位置时,探头接合轮毂,这导致轮毂和壳体响应于手柄的旋转而一起移动。 壳体连接到拱门的螺栓,其响应于壳体的移动而在锁定和解锁条件之间移动。
