ABSTRACT:
A shutter assembly which is comprised of a support frame formed by opposed parallel hollow side frame members and a bottom and top block member interconnected between the ends of the side frame members. A plurality of equidistantly spaced slats are pivotally inter-connected to one another and disposed between the side frame members in a parallel relationship. The side frame members each have a removably securable inner side wall which is provided with equidistantly spaced holes to receive opposed pivot pins of each of the slats. A slat positioning mechanism is disposed in one of the side frame members and has a pair of vertically disposed slat interconnecting bars. Pivot pin connectors are secured to each of the pivot pins and each has a pair of connecting arms pivotally connected to respective one of the slat interconnecting bars. A control gear, of circular disc shape, has gear teeth on at least an outer peripheral portion thereof. A controllable gear engaging mechanism is provided for rotating the gear to a desired position to displace the slat interconnecting bars to tilt the slats in unison to a desired angle and to retain them at that desired angle. The gear is also pivotally connected to a respective one of the pair of slat interconnecting bars.
