Abstract:
A transmission mechanism of a window covering includes a first lifting cord set, a second lifting cord set, and a driving cord set. The driving cord set has a cone reel and a control cord, wherein the cone reel has a gradually decreasing dimension, and the control cord winds around the cone reel and has a section left out of the headrail. The first and the second lifting cord sets each has a reel and a lifting cord, wherein the reel is driven by the cone reel, and the lifting cord has opposite ends fastened to the reel and the bottom rail respectively. The cone reel changes a speed and torque of the power transferred to the bottom rail while the user pulls the control cord to lift the bottom cord and the slats of the window covering in an efficient way.
