Abstract
Abstract A cabinet for a vertical room air conditioning unit includes an upper section and a separate lower section having substantially similar cross-sectional dimensions to permit mating of adjacent ends when the upper section is stacked upon the lower section in a use position. Securing means, including tabs and screws hold the sections together in the use position, and the upper section acts as a plenum or air duct for the unit. For shipment or storage, the upper section telescopes down onto the lower section, and after having been rotated 90 degrees in the preferred embodiment, to form a compact space saving package.
