Abstract:
A blind control for a window covering having a narrow profile; and particularly relates to a control module for a window shade where the location of the drive mechanism is selected to minimize the gap between the end of the window shade and inside edge of a window opening; locating the drive mechanism in a shell disposed in a housing to rigidify a reduced thickness of the drive so as to minimize the gap; and use a single rod depending from the control module to activate the drive mechanism in a safe and secure manner.
The invention also includes a housing with an end wall adjacent one end of the shade; a clutch projecting from said end wall and rotatable about a clutch axis, a drive gear engageable at one end of the clutch for rotatably driving said clutch and shade, said drive gear disposed in said housing adjacent said end wall; and a wand for driving said drive gear.
The invention provides for a wand to raise and lower the window shade.
