Window air conditioner unit mounting system

A window air conditioning unit mounting system comprising, in combination:

• a base subassembly having generally I-shaped configuration;
• a shackle being coupled to the base subassembly;
• a strut having a generally T-shaped configuration with a proximal portion and a distal portion, the strut being coupled to the shackle and to the base subassembly;
• an upper cross member comprising a pair of generally C-shaped components, being a larger component having a larger component interior and a smaller component having a smaller component interior, the larger component being sized to slidably receive the smaller component within the interior of the larger component, the larger component having an inner surface and an outer surface, the outer surface of the larger component having at least one protrusion, the upper cross member being coupled to an upper surface of an existing window air conditioning unit;
• the base subassembly having an inner end cross member and an outer end cross member, the base assembly inner end cross member having a first length with the base subassembly outer end cross member having a second length;
• the shackle having a generally C-shaped configuration, with a proximal end and a distal end, with a length there between;
• the proximal portion of the strut having a generally C-shaped configuration with an outer surface and two parallel side surfaces and an attachment end and a free end, with an intermediate length therebetween;
• the base subassembly inner end cross member having an inner portion and an outer portion, the inner portion having a generally C-shaped configuration with an upper surface and two parallel side surfaces, being an inner side and an outer side, the C-shaped configuration forming a recess therein, the outer portion of the inner end cross member having a generally rectilinear configuration with an upper surface and a lower surface and a peripheral edge there between, the base subassembly having an intermediate member having a generally C-shaped configuration with an upper surface and a lower surface and a pair of parallel side surfaces, each of the parallel side surfaces having a plurality of adjustment holes therein;
• the C-shaped configuration of the proximal portion of the strut forming an inwardly disposed recess, with each of the side surfaces of the proximal portion of the strut having a plurality of holes there through, the holes of the side surfaces of the proximal portion being sized to receive a strut adjustment pin;
• and
• the larger component and the smaller component of the upper cross member each having a plurality of locking holes there through, the locking holes being located so as to allow at least two of the locking holes through the larger component and the smaller component to be aligned.
