ABSTRACT:
An apparatus for opening and closing window blinds converts rotary motion about a vertical axis of a vertical rod into rotary motion about a horizontal axis of a horizontal member. A lever is attached to one end of the horizontal member. A drive gear is attached to an opposite end of the horizontal member. A driven gear is attached to a first end of a vertical member. The driven gear is operatively engaged with the drive gear. The vertical member is perpendicular with respect to the horizontal member. An adapter housing is attached to an opposite end of the driven gear and is used to attach a bottom end of the vertical rod thereto. All component parts are supported by a base member that is attached to a wall. Turning the lever rotates the drive gear which rotates the vertical rod and, accordingly, opens or closes the blinds.
