Patent ID: 7334420

Claim:
In an air conditioning unit having an air exchange opening therein, and a surface having a slope and an air exchange opening therein, a method comprising steps of; providing an adjustable framework adapted to be positioned upon the surface, the framework having a platform, a first frame, and a second frame coupled to the first frame for movement between a first position toward the first frame and a second position away from the first frame; adjusting the adjustable framework by moving the second frame one of away from the first frame and toward the first frame to define a generally horizontal condition of the platform relative to the slope when the adjustable framework is positioned upon the surface; securing the adjustable framework to form an adjusted framework; positioning and securing the adjusted framework upon the sloping surface; placing the air conditioning unit upon the platform; and coupling the opening in the air conditioning unit to the opening in the sloping surface; wherein the step of positioning and securing the adjusted framework upon the sloping surface comprises: pivotally attaching a first foot, having a sole, to the first frame; pivotally attaching a second foot, having a sole, to the second frame; presenting the first foot and the second foot upon the surface; pivotally adjusting the first foot and the second foot so as to present the soles thereof against the surface; securing the first foot to the surface; and securing the second foot to the surface; wherein the step of coupling the opening in the air conditioning unit to the opening in the sloping surface comprises: providing a plenum assembly comprising a first rigid plenum element, having an attachment end, coupled to a second rigid plenum element, having an attachment end, for movement between a first position toward the second rigid plenum element defining a retracted condition of the plenum assembly and a second position away from the second rigid plenum element defining an expanded condition of the plenum assembly; adjusting the plenum assembly between its retracted and expanded conditions so as to place the plenum assembly in an adjusted condition; the adjusted condition comprising the attachment ends of the first and second rigid plenum elements positionable concurrently against the air conditioning unit and the surface so as to engulf the openings therein, respectively; rigidly securing the first rigid plenum element to the second rigid plenum element in the adjusted condition forming an adjusted plenum assembly; coupling the attachment end of the first rigid plenum element to the air conditioning unit so as to engulf the opening therein; and coupling the attachment end of the second rigid plenum element to the surface so as to engulf the opening therein; the plenum assembly providing concurrent communication with the opening in the air conditioning unit and the opening in the surface.
