Abstract
Abstract A detent and detent release lever of a door lock are coaxially pivoted and provided with spaced opposed edge portions. A pin of an intermittent member supported on a locking lever is movable between the opposed edge portions to couple the levers or is movable out of engagement with one edge portion to uncouple the levers when the locking lever is respectively moved between unlocked and locked positions. The detent release lever is coupled to inside and outside operating means to release the detent when the levers are coupled. If the levers are uncoupled when the bolt is in unlatched position, they will remain uncoupled when the bolt is in unlatched position, they will remain uncoupled when the bolt moves to latched position to thereby provide a set and slam feature.
