ABSTRACT:
A one-piece adjustable air discharge register is of a generally clamshell-type of construction having a number of air-directing vanes formed integrally therein with the discharge register being adapted for pivotal mounting in an air discharge opening for adjustment of the flow of discharge air in a first adjustment direction. The discharge register also has a number of pivotally movable air-directing louvers formed integrally therein for adjustment of discharge airflow in a second adjustment direction transverse to, and independent of, the first adjustment direction. The one-piece discharge register includes an integral frame portion for supporting the movable louvers, with a number of sets of living hinges being integrally formed with the frame portion, the fixed vanes, and the movable louvers, in order to allow the register to be molded as a single, one-piece device and assembled in a simple one-step operation.
