Abstract
A tilt-latch (10) is adapted for releasably securing a pivotable sash window (12) disposed within opposed guide rails (16) on a master frame (14) of a window sash assembly (11). The sash window (12) comprises a top sash rail (20), a base (22) and two stiles (24,26) connected together at their extremities. The tilt-latch (10) comprises 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 (47) adapted for engaging a respective one of the guide rails (16). The latch bolt (46) further has a post (88). The tilt-latch (10) also has a spring (50) for biasing the latch bolt (46) through the outward end opening (44). An actuator (48) is connected to the latch bolt (46). The actuator (48) has a notch (90) that receives the post (88) of the latch bolt (46). The position of the notch (90) can vary on the actuator (48). This allows the distance the latch bolt nose (47) extends out of the housing (42) through the outward end opening (44) to be varied.
