ABSTRACT:
A tilt latch for a sliding window sash comprising a unitary molded plastic article including a base portion mountable on the top of a window sash, a body portion having a projecting nose for insertion in a channel of a window frame, and a narrow thin portion hingedly connecting the body to the base for enabling movement of the body between a closed position overlying the base and an open position. Two such latches are respectively mounted on opposite sides of a window sash; when the latch bodies are in the closed position, their noses are respectively received in vertical channels of the window frame for retaining the sash in the frame, while movement of the latch bodies to open position permits the sash to be tilted out of the frame. Each latch is provided with a manually releasable lock, such as a pin projecting from the base and received with interference fit in an opening of the body, for retaining the body in the closed position.
