Abstract
An air conditioner includes an outlet for discharging cool air into a room. The outlet can be closed by a vertically movable shutter. The shutter carries two vertical racks which are selectively engageable by a horizontally shiftable, motor-driven pinion. The pinion, which is rotated in only one direction, displaces the shutter into an outlet closing position when the pinion engages one of the racks, and displaces the shutter in an opposite direction when the pinion engages the other rack. Horizontal shifting of the pinion can be performed by tripping jaws which are formed on the racks and are engageable with the pinion, or by a separate device such as a fluid-actuated cylinder.
