Abstract:
A shutter assembly comprising a support frame formed by opposed parallel hollow side frame members and bottom and top block members each connected to said side frame members adjacent an associated pair of opposed ends of said side frame members; a plurality of equidistantly spaced slats are pivotally secured between said side frame members in pivotal parallel relationship and pivotally interconnected to one another in one of said hollow side frame members, said side frame members each having a removably securable inner side wall provided with equidistantly spaced holes each receiving an associated one of a pair of opposed pivot pins of each said slat, a slat positioning mechanism is disposed in said one of said side frame members, said positioning mechanism having a pair of vertically disposed slat interconnecting bars, pivot pin connectors secured to said pivot pins, each of said pivot pin connectors having a connecting bore secured to one of said pivot pins of said slats, each of said pivot pin connectors further having a pair of connecting arms each pivotally connected to a respective one of said pair of slat interconnecting bars, one of said connecting arms of each said pivot pin connector projects from a spacing base formation disposed above a base of said pivot pin connector which maintains said slat interconnecting bars in spaced parallel planes, a control gear having a circular disc shape is provided with gear teeth on at least an outer peripheral portion thereof, said gear having a pair of pivotal connections secured to a respective one of said pair of slat interconnecting bars, said pair of pivotal connections having a pivot axis extending parallel to an axis at a center of said gear, controllable gear engaging means for rotating said control gear to a desired position to displace said interconnecting bars to tilt said slats in unison to a desired angle and to hold said slats at said desired angle.
