Sash lock and tilt latch also functioning as a window vent stop, with automatic locking upon closure
A sash window fastener includes: a latch assembly; a sash lock assembly mounted upon the meeting rail; and a stop member mounted to the master window frame. The lock assembly includes a pivotable cam to engage a keeper on the master frame to lock the window, and a pivotable follower arm. The arm interconnects with the latch assembly within the meeting rail, so cam rotation that drives arm rotation also causes translation of the latch. The cam may occupy: an extended position to secure the cam to the keeper, with the latch engaging the master frame to prevent tilting, and being positioned below a protrusion on the stop member to redundantly lock the window; a first retracted cam position permitting sliding of the window; and a second retracted position permitting tilting of the sash window. Additional protrusions may be used on the stop member to serve as vent stop positions.
