ABSTRACT:
A lock assembly of a door preparation includes at least one spring latch member which is spring biased within a door jamb bore between an extended position and a retracted position in which the spring latch member, when the door is being opened, engages a strike plate of the door jamb and is moved inwardly within the door preparation for allowing the door to be opened. A dead bolt, which operates independently from the spring latch member, is movable between a retracted position in which it is within the door preparation and an extended position in which it is extended within the door jamb bore for locking the door. A projecting pin is movable between a first position in which the projecting pin is disposed generally between the spring latch member and dead bolt and a second position in which the pin projects laterally outwardly from a peripheral edge of the spring latch member when the dead bolt is moved to its extended position to engage the strike plate. The projecting pin has a detent element which rides within a cam track formed in the dead bolt for moving the projecting pin between its first and second positions. The lock assembly further includes an actuating assembly for moving the dead bolt between its retracted and extended positions.
