DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to an airconditioning or heating facility, or both an airconditioning and heating facility, such as a reverse cycle facility, adapted specifically for providing airconditioned air or heated air, or selectively both, for vehicles such as trucks.
BACKGROUND ART
With trucks hauling loads over long distances it is common practice for drivers to stop for periods of rest or sleep at roadside parking areas, sometimes associated with restaurants or other facilities, whilst the truck has sleeping facilities for the driver. Such trucks are conventionally airconditioned and heated via their own vehicle mounted airconditioning or heating units which operate whilst the prime mover's engine is running and which is satisfactory when the truck is in motion. However, when the truck is stopped for the driver to have rest or sleep it is not practical for the engine to remain running for what may be many hours. As a result, during hot or cold days and nights the interior of the cabin of the truck becomes hot or cold which is not conducive for driver comfort whilst resting or sleeping.
It is therefore an object of the present invention to provide a road side airconditioning or heating facility, or facility for both airconditioning or heating, whereby airconditioned and/or heated air as required can be introduced into the cabin of the vehicle.
DISCLOSURE OF THE INVENTION
The invention therefore envisages a road side airconditioning and/or heating facility in, or adjacent, a parking bay for a vehicle, including and supporting, in use, an airconditioning unit and/or heating unit, or reverse cycle unit, relative to said vehicle and for temporary association with the vehicle, and having an outlet from the unit, and means, in use, to associate the outlet with the interior of the cabin of the vehicle, whereby conditioned and/or heated air may be supplied to the cabin of the vehicle.
Preferably the means to associate the outlet with the interior of the cabin of the vehicle is a supply duct connected to the outlet and supplying the cabin of the vehicle.
Preferably the supply duct is a flexible duct.
Preferably the operation of the facility is controlled by a coin, token or card operated control means controlling electrical power supply to the unit.
Preferably the outlet is associated with means adapted to be jammed between the top of the window frame of the door of the vehicle and an adjustable window panel within the door frame.
Preferably the unit further has at least one inlet with means to also, in use, associated the inlet with the interior of the cabin of the vehicle and return air to the unit.
Preferably the means to associate the inlet with interior of the cabin of the vehicle is a return duct, and preferably the return duct is a flexible duct.
Preferably the unit is supported by means allowing the height of the unit to be adjusted.
Preferably the means supporting the unit also allows from lateral adjustment of the unit into and out of the parking bay.
BRIEF DESCRIPTION OF THE DRAWING
One preferred embodiment of the invention will now be described with reference to the accompanying drawing, which is a schematic view of a road side airconditioning and/or heating facility.
BEST MODE FOR CARRYING OUT THE INVENTION
Referring to the drawing, there is shown schematically a supply unit 10 for conditioned air, or heated air, or both, such as by a reverse cycle unit. In the particular example of the invention the supply unit incorporates an airconditioning unit 11 which may be a domestic airconditioning unit of the type that conventionally may be permanently mounted through walls or window spaces of a dwelling. The airconditioning unit 11 supplies conditioned (cooled) air to a box shaped supply chamber 12.
A flexible supply hose 14a is provided and adapted to be plugged into an outlet from the chamber 12, or permanently attached to the outlet, and of a length sufficient to reach the window space of a door 16 through which access to the cabin of a vehicle is obtained. A flexible return
