ABSTRACT:
A door lock includes a bracket fixed to a door. A linking rod is slideably mounted to the bracket and includes a slot. A draw member includes a first end pivotably connected to the bracket and a second end operably connected to a retractor. The draw member further includes a guide slot. A pin slideably extends through the slot and the guide slot such that the movement of the linking rod causes pivotal movement of the draw member, which in turn, urges the retractor to move a latch bolt from an extended position to a retracted position. A follower is coupled to the pin to move therewith. An adjusting member is in threading connection with the follower and rotatable to move the follower and the pin relative to the linking rod to adjust a position of the second end of the draw member relative to the retractor.
