ABSTRACT:
A tilt latch (10) for a sash window (12) has a bolt stop. The sash window (12) is disposed within opposed guide rails (16) on a master frame (14). The sash window (12) is comprised of a top sash rail (20), a base (22) and two stiles (24,26) connected together at their extremities. The tilt-latch (10) is adapted for releasably securing the sash window (12) to the master frame (14). The tilt-latch (10) is comprised of a housing (42) adapted to be supported by the top rail (20). The housing (42) has an outward end opening (44). A latch bolt (46) is disposed within the housing (42) and has a nose adapted for engaging a respective one of the guide rails (16). A protrusion (80) is located either on the latch bolt (46) or the housing (42) and a lock wall (86) is located either on the housing (42) or the latch bolt (46). The protrusion (80) has a stop surface (84) and is moveable between a first position defining a prevent position (94) wherein the stop surface (84) is adapted to abut the lock wall (86) to prevent retraction of the latch bolt (46) into the housing (42), and a second position defining a deflected position (96) wherein the stop surface (84) does not abut the lock wall (86) to allow retraction of the latch bolt (46) into the housing (42). The protrusion (80) is biased to the prevent position.
