Abstract
Abstract Portable air conditioner apparatus designed primarily for use with recreational vehicles includes an air conditioner unit having wheels for portability and a head adaptor assembly which is vertically adjustable with respect to the unit for alignment with a window in the vehicle. The head adaptor unit consists of an insulated pan communicating with the air conditioner unit through flexible hoses. The pan is sufficiently deep to receive jalousie windows or the like when open, and has a peripheral gasket about its open end for sealing contact with the vehicle. Leveling mechanisms may be provided on both the front and back of the air conditioning unit properly to position such unit and assembly with respect to the vehicle for effectuation of a tight seal.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
123 words
A portable air conditioner apparatus for use with recreational vehicles or the like comprising an air conditioning unit having a cool air discharge port and a return port, a vertically adjustable head adaptor assembly having a pan shape housing, flexible air ducts connecting said cool air discharge port and return port to said housing, said head adaptor assembly being vertically adjustable relative to said air conditioning unit to position said pan shape housing sealingly against the side of a vehicle about an opening therein, whereby cool air may selectively be delivered to the vehicle through the air duct connected to said cool air discharge port and relatively warmer air removed from the same through the air duct connected to said air return port.
Claim 2
Dependent Claim
123 words
A portable air conditioner apparatus for use with recreational vehicles or the like comprising an air conditioning unit having a cool air discharge port and a return port, a vertically adjustable head adaptor assembly having a pan shape housing, flexible air ducts connecting said cool air discharge port and return port to said housing, said head adaptor assembly being vertically adjustable relative to said air conditioning unit to position said pan shape housing sealingly against the side of a vehicle about an opening therein, whereby cool air may selectively be delivered to the vehicle through the air duct connected to said cool air discharge port and relatively warmer air removed from the same through the air duct connected to said air return port.
Claim 3
Dependent Claim
29 words
The apparatus of claim 1 wherein said head adaptor assembly is mounted by jack support means to said air conditioning unit for controlled vertical adjustment relative to said unit.
Claim 4
Dependent Claim
73 words
The apparatus of claim 1 wherein said air conditioning unit Is mounted on front wheels, and leveling means are provided to position said unit and supported head adaptor assembly at an inclination similar to that of a vehicle, whereby said apparatus may readily be moved from one vehicle to another and positioned so that said head adaptor assembly may cooperatively mate with the similarly inclined vehicle side for effectuation of a tight seal.
Claim 5
Dependent Claim
67 words
The apparatus of claim 3 wherein said leveling means includes a leveling apparatus connected to the back of said unit, said leveling apparatus comprising a threaded rod threadably connected to said unit for selective vertical movement relative thereto and a base plate connected to the bottom of said rod to support the back of said unit at a position correlative to the relative position of said rod.
Claim 6
Dependent Claim
69 words
The apparatus of claim 4 wherein said leveling apparatus further comprises a tubular member for receipt of the upper end of said threaded rod, a longitudinal slot in the side of said tubular member, a pin extending laterally from the upper end of said threaded rod through said slot, and means for rotating said tubular member to cause axial movement of said threaded rod relative to said tubular member.
Claim 7
Dependent Claim
41 words
The apparatus of claim 5 wherein said means for rotating said tubular member comprises a second rod suspended from the top of said unit, and an exposed knob on the upper end of said second rod for rotating said second rod.
Claim 8
Dependent Claim
66 words
The apparatus of claim 4 wherein said front wheels are mounted to a pivotal axle and said leveling means further includes a second leveling apparatus connected to the front of said unit, said second leveling apparatus comprising a link of adjustable length with the bottom of said link being connected to said axle, whereby adjustment of the link length results in pivotal movement of said axle.
Claim 9
Dependent Claim
47 words
The apparatus of claim 1 wherein said pan-shaped housing has a gasket extending around the entire periphery of the open end thereof to effect a seal with the vehicle side, said housing being sufficiently deep to receive windows and the like that open outwardly from the vehicle.
Claim 10
Dependent Claim
48 words
The apparatus of claim 1 wherein said panshaped housing has inlet and outlet apertures in the base wall thereof with outwardly extending hose mounting stubs about said apertures, said pan-shaped housing and inlet mounting stub being insulated to minimize heat gain in the cool air from said unit.
Claim 11
Dependent Claim
46 words
The apparatus of claim 1 wherein said duct for cool air between said cool air discharge port and housing inlet aperture is insulated by placing a second concentric duct about the first duct, such concentric relationship being maintained by peripherally located spacer elements between said ducts.
Claim 12
Dependent Claim
26 words
The apparatus of claim 1 wherein said head adaptor assembly is mounted for pivotal movement between an upright operative position and a collapsed lower inoperative position.
Claim 13
Dependent Claim
60 words
The apparatus of claim 11 wherein said head adaptor assembly is mounted by jack support means to said air conditioning unit for controlled vertical adjustment relative to said unit, and means are provided for pivoting said jack support means and thus said head adaptor assembly to said unit for pivotal movement between such upright operative position and lower inoperative position.
Claim 14
Dependent Claim
26 words
The apparatus of claim 12 further comprising means for releasably locking said jack support means and thus said head adaptor assembly in such upright operative position.
Claim 15
Dependent Claim
45 words
The apparatus of claim 13 wherein said last-mentioned means comprises a fixed plate on said unit having an opening therein, and an axially movable lock element on said jack support means axially movable into and out of engagement with said opening in said fixed plate.
Claim 16
Dependent Claim
28 words
The apparatus of claim 14 further comprising means for preventing movement of said head adaptor assembly relative to said jack support means when in the lower inoperative position.
Claim 17
Dependent Claim
32 words
The apparatus of claim 1 wherein said air conditioning unit includes a blower motor encased in an insUlated split housing to facilitate assembly of said unit and field maintenance of said motor.
