An elevator escape arrangement includes a hinged window on a car; an escape rope passed by the window; a spring biased linking mechanism interconnected the window and a door; and a drive assembly including a first shaft, a detent block on the first shaft and between two brake bars, a cam-like member engaged with a drive sheave, a pulley on the first shaft with the escape rope run, a first gear on the first shaft, a second gear meshed with the first gear, and a second shaft passed through the second gear and the cam-like member. In case of emergency with the car stuck between two floors, the car and a counterweight balanced, and the brake activated, opening the window will cause the linking mechanism to lock the door, pulling the escape rope will unbalance and move the car, and closing the window will unlock the door for escape therethrough.
