摘要：A vent register for controlling the flow of air from a heating and cooling duct system. The register includes a rack and pinion operating mechanism for controlling the movement of the damper louvers. The louvers are molded with an integral pinion gear and rotatably mounted within a rectangular housing. A slidably movable lever having a
lineal rack of teeth is disposed within the housing. A portion of the lever protrudes above the face of the register for manipulation by the user and the rack of teeth engage the pinion gears of the louvers. The linear adjustment of the lever within the housing is translated to rotational adjustment of the louvers by the rack and pinion operating mechanism.
