Abstract: A lock assembly for use with a door movably coupled to a door frame. The lock assembly includes a housing, a control member, a latchbolt, and a locking member. The control member is movably coupled to the housing from a locked position to an unlocked position to allow the door to move with respect to the door frame. The latchbolt moves with respect to the housing in a first direction and a second direction. The locking member is configured for engagement with the control member to move the locking member with respect to the housing into and out of an engaged position with respect to the latchbolt. The locking member includes a surface that contacts the latchbolt when the locking member is in the engaged position to substantially prevent movement of the latchbolt in the first and second directions.

Abstract: A latchbolt configured for use with a door lock assembly. The door lock assembly is configured for interaction with a strike coupled to a door frame, and operable to place the latchbolt in a locked configuration using the strike to generally prevent rotation of the door and an unlocked configuration to allow rotation of the door. The latchbolt includes a first member and a second member movably coupled to the first member. When the latchbolt is in the locked configuration the second member is movable relative to the first member from a first position to a second position in response to a predetermined force applied to the door.
