Abstract

See full text

The structures described herein use an actuating system that can selectively switch between a lower and a raise mode of operation by rotating a rod assembly in two different directions, and use a downward displacement of a pull member to lower and raise the window shade depending on its switching state. The actuating systems are simple to operate, allow convenient adjustment of the window shade, and are safe as the pull member has a limited length of extension.
