Patent ID: 7399222

Claim:
An auto-shutter operating apparatus for use in an air-conditioner having an external casing including a first side having an air exit opening therein, the auto-shutter operating apparatus comprising: a louver frame, having an exit opening therein, mounted in said casing with the exit opening of the casing and louver frame in alignment; an auto shutter movably mounted in said frame for movement between an opened position opening the exit opening of the louver frame and a closed position closing the exit opening of the louver frame; and shutter driving means for driving the auto-shutter between said open and closed positions, said shutter driving means comprises: a drive motor having a housing and means for rotatably mounting said housing to allow the motor to tilt forwardly and backwardly relative to said first side; a rotational rod having a screw thread formed along its outer surface and being coupled to said driving motor for rotation along its longitudinal axis by said motor; a bushing coupled with said rotational rod for reciprocal movement therealong in response to the rod being rotated by said motor in either a first or second rotational direction; a slider having a first end pivotally coupled with the auto-shutter and a second end coupled to said bushing; a rotational rod guider mounted in said frame which guides and supports rotation of the rotational rod; guide rails formed on opposed surfaces of said louver frame adjacent said exit opening therein; and means on said auto-shutter engaged with said guide rails for guiding movements of the auto-shutter, said guide rails having a predetermined shape defining a path of travel for the auto-shutter to cause said motor and rotational rod to tilt toward and away from said first side as said auto-shutter approaches and leaves said closed position thereof.
