An air conditioning unit discharge opening includes an inlet and outlet side and a pair of spaced walls. Each of the walls has a mounting pin formed thereon, which extends in a direction toward the other wall such that the mounting pins together define a longitudinal axis extending therebetween. An air discharge nozzle has an inlet side and an outlet side and a pair of spaced substantially planar walls. The nozzle is configured to be received within the air discharge opening with the planar walls of the nozzle in closely adjacent relationship with the planar walls of the discharge opening. Pin receiving conformations are formed on each of the planar walls of the nozzle. Each of the conformations includes an open ended slot extending into the wall from the inlet side and an arcuately shaped pin receiving socket formed at the inner end of the slot. The sockets are configured to receive the mounting pins therein in a snap-fit relationship and to allow pivotal movement of the air discharge nozzle about the longitudinal axis. In a preferred embodiment, one of the side walls defining the air discharge opening includes an outwardly extending tooth-like protuberance adjacent the mounting pin. The wall of the discharge nozzle adjacent the wall carrying the pin is provided with an arcuate tooth engaging conformation, which is adapted to releasably engage the tooth to allow movement of the air discharge nozzle upon imparting an external rotational force thereupon and yet holding the air discharge nozzle at a desired position upon release of the external force. |
