ABSTRACT:
A door latch assembly for a pyrolytic self-cleaning oven which includes a locking plate and a bolt cooperating with a striker on the oven door. A slot adjacent the locking plate communicates with spaced-apart shallow and deep notches. A locking finger is shiftable in the slot and biased toward the notches, the finger having an actuator for drawing it into shiftable position in the slot clear of the notches. A first abutment is provided on the locking plate having a path of movement alined with the slot but clear of the notches so that when the actuator is de-energized and the finger occupies an idle position in the shallow notch, the locking plate and bolt are freely movable by an operating handle between free and bolting positions and so that, when the actuator is energized and the locking plate moves fully into bolting position, the first abutment moves the finger to a position opposite the deep notch. A second abutment is provided on the locking plate faced oppositely to the first abutment and having a path of movement alined with the root of the deep notch so that when the actuator is de-energized the finger drops into the deep notch, securely blocking the locking plate, and thus the bolt, in bolting position. A third abutment returns the finger to idle position following re-energization of the actuator.
