LOCK HAVING MAID LOCK-OUT AND DEADBOLT PROTECTOR

This lock, which may be coded-keycard operated, has a set-table device on the inside of the door by which the maid, for instance, can be locked out. The lockout setting device is preferably in the form of a pushbutton or deadbolt turnpiece which manipulates a switch in the code-receiving circuitry. The lock-out setting is automatically cancelled when the latch is retracted. When the setting device comprises a deadbolt turnpiece, the deadbolt is biased toward retracted position and the setting device holds the deadbolt extended. When the latch is retracted in the latter version, the retraction cancels the lockout setting and permits the deadbolt to retract under the power of the dead-bolt biasing spring. The invention also includes a non-code-operated embodiment in which a deadbolt is spring driven to retracted position as the latch is retracted in latching to protect the deadbolt, lock and door frame.
