ABSTRACT:
A dual function lock, a tilt latch assembly, and tilt latch for use on a hung or double hung window are provided. The lock includes a base, a handle, and a tilt latch actuating mechanism. The tilt latch assembly includes a lock, left and right latches, and an extensible member. The tilt latch actuating mechanism is adapted to receive the extensible member and has a null zone between locked and unlocked positions of the handle. In the null zone, no substantial movement of the extensible member as the handle is rotated from the locked to unlocked positions. The tilt latch actuating mechanism causes the extensible member to move in a direction toward the lock as the handle is rotated from the unlocked position to a tilt position.
