Abstract
A mechanical latch assembly includes a supporting frame, a locking latch, an actuation arrangement and a safety lock arrangement. The locking latch is slidably mounted on the supporting frame in longitudinally movable manner. The actuation arrangement includes an actuation handle pivotally connected to the supporting frame to longitudinally drive the locking latch moving between a locked position an unlocked position. Moreover, the safety lock arrangement includes a locker member movably mounted on the supporting frame, wherein the locker member has a slider slot formed thereon to define a pusher surface and an opposed retracting surface, and a thermal activated arm substantially extended from the supporting frame to slidably pass through the slider slot of the locker member at a safety temperature, and adapted to deflect to push the locker member at the pusher surface at an elevated operation temperature.
