ABSTRACT:
An air conditioner has a discharge outlet for discharging air, and a plurality of adjustable blades arranged across the outlet for controlling the direction of air discharged through the outlet. The blades are rotatable about parallel axes and are arranged in groups of blades. Each group is connected to a reciprocable connecting rod, whereby the blades rotate when their respective connecting rod is reciprocated. The connecting rods are interconnected in end-to-end relationship by slip joints. A motor connected to one of the connecting rods can reciprocate all of the connecting rods together for simultaneously adjusting all blades. When the motor is off, the blade groups can be manually rotated relative to one another, as permitted by slippage in the slip joints.
