ABSTRACT:
A door latch mechanism, mountable in an oven for engagement with an oven door, includes a base, a latch plate carried on the base by a pair of flanged guide rollers carried on the base and cooperating with a pair of guide slots in the latch plate, and a yieldable over-center urging means pivotally engaged with the latch plate and reciprocably received by a support on the base, the latch plate being carried by the base for movement between an extended position and a retracted position corresponding to open and closed positions, respectively, of the oven door. The mechanism, in one embodiment, further includes a lock for securing the latch plate in its retracted position and a thermally responsive interlock for retaining the lock in a locked position when the oven is operative.
