A latch assembly is provided where a latch bolt is moveable to open and close a door by unblocking pivotal movement of the latch bolt. Turning a door knob or door handle does not directly result in a corresponding retraction of the latch within a sleeve, but rather unblocks the bolt to freely pivot away from a latched position. In some embodiments, the latch assembly may include a sleeve that allows for a backset to be infinitely adjusted relative to an aperture of the sleeve. In some embodiments, the latch assembly may further include a dead latch to provide additional security against forced entry.

A door lock system comprising a first rotary configured to control extension and retraction of the deadbolt via a primary cam mechanism; a second rotary control configured to control extension and retraction of the latch; and a link configured to retract the deadbolt in response to operation of the second rotary control when the latch is retracted by the second rotary control. The link is configured to move along a linear path normal to the movement of the deadbolt and the door latch and to contact the primary cam mechanism upon the link movement to affect deadbolt retraction and extension. A lever may be used to retract the latch in response to rotation of the first rotary control in a first rotational direction when the deadbolt is retracted by the first rotary control.
