Abstract
An apparatus for opening and closing window shutter slats or louvers converts rotary motion by a knob or electric motor into rotary motion of one of the slats. The apparatus is attached to a frame structure that is included with the window shutter and which surrounds the slats. A connecting rod that is pivotally attached to all of the slats pivots all of the slats an amount that is nearly equal to that of the one slat. The knob includes a first shaft that is attached to a drive gear in an enclosure which turns a driven gear. The driven gear is attached to a second shaft which is adapted to turn a pin end of the one slat. The motor is adapted to rotate one of the slats directly. Retrofit use and use in newly manufactured shutters is described. The apparatus can also be used to pivot open the shutter with respect to a pair of hinges that pivotally attach the shutter to a surrounding support structure.
