ABSTRACT:
A locking mechanism for security doors such as safes. A mounting plate is provided for attachment to the inner surface of the door. A cylindrical activating member is mounted on a pin for rotation about an axis normal to the inner surface of the door. The activating member contains a plurality of activating fingers and mounting posts for connecting to locking pin actuating mechanisms directly or through linkages. A groove is provided in the periphery of the activating member. A pair of sliding members are mounted to the plate. One sliding member is positioned to slide into the groove to prevent rotation of the activating member. The second sliding member is adapted to slide into abutment with the first member to prevent sliding thereof. Standard lock mechanisms of the combination or pin tumbler type for use with a key are mounted to the plate and connected to the two sliding members to control their movement.
