An automatic safety latch assembly for use in combination with a striker on a door of a self-cleaning kitchen range has a bolt which is mounted for rotational movement and subsequent longitudinal movement to a latched position. An over-center biasing arrangement is provided to bias the latching mechanism into both the latched and unlatched positions of the latch bolt. A door sensing element is cooperatively engaged with the latch bolt to prevent accidental tripping of the latching mechanism until the oven door is properly positioned. The latching mechanism includes a thermally responsive blocking mechanism to lock the latch bolt in the latched position and prevent the opening of the oven door during the high temeprature self-cleaning cycle of the kitchen range.

An automatic safety latch for use in combination with an oven door in a self-cleaning kitchen range having a striker on the door to be engaged therewith, said latch comprising: a. a base plate; b. a latch bolt projecting beyond said base plate and having a slot extending inwardly from one side margin of said projecting portion adapted to receive and engage the associated striker; c. means mounting said latch bolt on said base plate for initial rotational movement from an unlatched position to an intermediate position in which the associated striker is aligned in said slot and for subsequent generally rectilinear movement to a latched position to fully seat the associated striker within said slot; d. biasing means biasing said latch bolt into each of said unlatched, intermediate and latched positions and permitting said rotational and rectilinear movement of said latch bolt, said biasing means including a latch member, means pivotably mounting said latch member to said latch bolt and for movement between a first position and a second position in which said bolt is latched, and spring means biasing said latch member and thereby said latch bolt into each of said unlatched, intermediate and latched positions thereof; e. door sensing means operable upon closing of the associated door to permit movement of the latch bolt into the latched position; f. locking means movable on said base plate from a first position to a second position operatively engageable with said biasing means in the latched position of said latch bolt to prevent movement of said biasing means and thereby said latch bolt from the latched position to the unlatched position, said locking means being movable from a first position to a second position and being engageable with said latch member to prevent its movement from its second position to its first position and thereby to lock the latch bolt in its latched position; and g. actuating means for moving said locking means to said second position and operable upon movement of the associated oven door to the fully closed position.
