A door lock unit configured to block a latch when a bolt is extended

Abstract

The invention relates to a door lock unit (1) comprising - a latch (10) that is movable between an extended position and a retracted position, - a latch hub (20), - a latch interlock (15) that is movable between a latch block position (15B) in which the latch (10) is blocked in its extended position, and a latch release position (15R) in which the latch (10) is not blocked in its extended position, - a bolt (30) that is movable between an extended position and a retracted position, - a bolt hub (40), - a three-way link member (50) that is connected to the bolt hub (40), to the bolt (30) and is configured to be brought into contact with the latch interlock (15), the three-way link member (50) being movable between a lock position (50L) in which the bolt (30) is in its extended position and an unlock position (50U) in which the bolt (30) is in its retracted position. The door lock unit (1) is configured such that the three-way link member (50) in its lock position (50L) may block the latch interlock (15) in its latch block position (15B) to block the latch (10) in its extended position.
