Abstract
A magnetic transmission system for an adjustable curtain installed inside a double pane window. Under full insulation condition of the double pane window, by use of two magnetic pieces separated by the glass, the rotation of the magnetic pieces will drive a pull cord, which will then effectively control and adjust the status of the curtain which is installed inside the window. The invention provides large transmission power in a small space. In addition to the typical thermal and acoustic insulation functions, the invention adds additional function of easy and flexible light adjustment. The invention can be widely used in different applications, such as standard home doors and windows, movable windows and large-scale windows, door and glass walls, skylights, etc.
