Abstract: 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.
