Abstract
A window latch assembly for locking first and second windows together includes a cover member coupled to the first window, and a handle pivotably coupled to the cover member. A lock member is fixedly coupled to the handle and has a lock portion adapted to protrude beyond a planar extent of the cover into a locked position, wherein the lock portion engages a lock keeper coupled to the second window, and an unlocked position, wherein the lock keeper is retracted inside the cover member. A mechanical finger is movable between a first position allowing the lock portion to be moved from the unlocked position to the locked position, and a second position preventing the lock portion from being moved from the unlocked position to the locked position, thereby preventing damage of the first and second windows.
