Abstract:
A motorized shutter assembly comprising:(a) a frame having a pair of parallel spaced frame members; (b) a multiplicity of louver slats extending between said frame members and having shafts extending into and pivotably seated in said frame members; (c) coupling means engaged with said louver slats to produce concurrent pivotal movement of said louver slats in either direction; (d) an adapter on one of said frame members and having a drive portion engaged with the end of one of said louver slats, said adapter being rotatable to effect pivotal movement of said one of said louver slats and thereby said multiplicity of slats in either direction; (e) a reversible drive motor assembly engaged with said adapter to effect rotation of said adapter drive portion and thereby said slats in either direction, said drive motor assembly including a multiplicity of intermeshed gears including input and output gears to reduce the speed of rotation from that of the driven input gear and to increase the torque provided by said output gear, said adapter including a clutch to protect the gears of said gear assembly from injury in the event of an obstruction preventing, or manual action causing, rotation of said slats, said adapter also including a body member with a base wall, a side wall, a recess therein, and a transverse slot seating the end of said one of said louver slats, a shaft extending therethrough, a coil spring in said recess extending about said shaft, a washer bearing on the outer end of the spring, a clutch plate bearing upon the outer surface of said base wall, and interengaging means on said base wall and clutch plate; (f) power supply means for said drive motor assembly; and (g) control means for said power supply means.
