1. An air conditioner comprising:
- a housing forming a cool air outlet;
an outlet closing mechanism mounted to the housing and including;
a shutter movable vertically between outlet-pen and outlet-closed positions;
a motor having a drive axle rotatable in only one direction of rotation;
a pinion fixed to the axle to be rotated thereby in the one direction of rotation; and
a vertical rack structure connected to the shutter the rack structure being engageable with the pinion and driven by the pinion to at least one of the outlet-open and outlet-closed positions, wherein the rack structure comprises horizontally spaced first and second vertical racks, the pinion being shiftable into mesh with only the first rack for moving the shutter in one vertical direction into the outlet-open position in response to rotation of the pinion in the one direction of rotation, the pinion being shiftable out of mesh with the first rack and into mesh with the second rack for moving the shutter in another vertical direction opposite the first vertical direction into the outlet-closed position in response to rotation of the pinion in the one direction of rotation.

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.
