ABSTRACT:
An anti-panic lock assembly for a door and associated methods are provided. The lock assembly can be used to secure the door to a keeper structure mounted in a jamb of a door frame so that the assembly can be adjusted by first and second handles extending from the opposite sides of the door. The lock assembly generally includes a latch assembly with a latch member and a deadbolt assembly with a deadbolt member for engaging the keeper structure. The latch member is configured to be adjusted by a rotation of the handles between its extended and retracted positions. The deadbolt member is configured to be adjusted by a rotation of a deadbolt handle and a key lock mechanism between its extended and retracted positions. The assembly can be installed to provide an anti-panic feature from a select side of the door, by using a selective connection feature to selectively link one of the handles to the deadbolt assembly. In a first configuration, the first handle can be configured to adjust the deadbolt assembly to an unlocked configuration while the second handle is locked. In a second configuration, the second handle can be configured to adjust the deadbolt assembly to an unlocked configuration while the first handle is locked.
