A door construction for hingedly mounting a room air conditioner control area access door on the front cover panel. The door includes an L-shaped angle extension formed integrally with the door rearwardly pivoted vertical edge. The construction defines a recessed shoulder positioned in an offset manner from the door outer face so as to underlie a free edge of the panel when the door and panel are in co-planar relation to limit inward flexing of the panel. The angle is further adapted, upon opening of the door, to be movable into engagement with a portion of the control area housing to positively limit the pivotal location of the door to obviate contact of the door outer decorative face with the panel free edge.

Mounting for room air conditioner access door

A self-alignment clip for use in assembling a shaft switch flat surface into the cylindrical axial bore of a hub. The U-shaped clip is readily fastened on the hub so as to straddle a portion of the hub end such that the clip inner arm is located in the hub axial bore and its outer arm has means for snap-on engagement with a set screw bore. The inner arm permits the flat of the shaft to be readily aligned in telescoping relation with the inner arm such that the shaft set screw or the like is aligned in normal fashion with the flat of the shaft.

A door operating mechanism for an air conditioning unit including a bellcrank actuator and pressure plate assembly having an offset pivot point. The outer end of the actuator arm is connected to the door by a resilient linear push-pull rod. The door is releasably retained in a plurality of intermediate open positions by rotation of the actuator between its closed or fully open position and with the push-pull rod having a predetermined length with respect to the door and the actuator in its closed position whereby upon the actuator being retained in its door closed position, the push-pull rod is resiliently bowed to provide a biasing force on the door to retain the same in a substantially air-sealed arrangement with the door opening.

An electrical grounding clip for grounding the outer casing of a room air conditioner to the base pan of the chassis in a manner to assure positive grounding contact upon the chassis being slidably inserted within the casing. The clip includes a U-shaped body portion forming two leaf portions normally oriented at an outwardly diverging angle, the casing engaging leaf being formed with a pair of spring legs and a cooperating lanced portion for engaging a pair of cooperating openings in the lower wall of the casing. The chassis engaging leaf portion includes an upwardly extending central cone having a sawtooth-like edge for resilient biased grounding connection with the chassis base pan.

A room air conditioner wall sleeve and subbase assembly for a 277 voltage range permanently wired installation located in a room wall opening. The subbase casing has a pair of side-by-side removable covered openings providing access to separate enclosures, one of which encases an electrical outlet receptacle for the power cord plug of the air conditioner chassis while the other enclosure encases the permanent field or 'hard' wiring connection for the installation. The access cover for the power cord receptacle enclosure has a self-contained outwardly formed shield, including an upwardly extending portion that defines, with the sleeve front flange and sleeve front assembly, a convenient code approved electrical duct passage for encasing the power cord.
