ABSTRACT:
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.
