Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to auxiliary power and air handling systems and more particularly to an auxiliary vehicle rest station for providing auxiliary power and air handling capabilities to trucks, particularly over-the-road or long haul vehicles whose drivers are required to observe mandatory periods of rest and down-time.

2. Background

The prior art includes a variety of auxiliary air conditioning and heating systems to be used by trucks or other vehicles, see for example U.S. Pat. No. 7,259,469 to Brummett, et al., U.S. Pat. No. 5,333,678 to Mellum, et al., and U.S. Pat. No. 4,762,170 to Nijjar, et al., all which teach auxiliary units that include a separate truck mounted auxiliary engine. Additionally, the prior art includes a variety of auxiliary air conditioning and heating systems that employs a fuel cell, see for example, U.S. Pat. No. 7,543,454 to Harris, U.S. Pat. No. 7,216,812 to Eberspach, et al., U.S. Pat. No. 7,090,043 to Liu, et al., and U.S. Pat. No. 6,454,180 to Matsunaga, et al.

While these devices may provided the advantage of serving to reduce emissions by allowing a vehicle operator to shut down the vehicles engine during rest stops, switching over to a smaller more efficient auxiliary power source, the disadvantage with each is found in the fact that the owner or operator of the vehicle would have to undertake the additional investment required to purchase and install the unit, find the space on the vehicle to accommodate the auxiliary unit and undertake the maintenance of the unit in addition to the cost and time dedicated to maintenance of the vehicle itself.

IdleAire Systems of Knoxville, Tenn. manufactured and installed a number of its IdleAire Service Delivery Modules which include a gantry mounted auxiliary heating, cooling and ventilation unit positioned above a parking space for the vehicle. A vehicle is positioned below the gantry and the gantry mounted module is connected to the vehicle by a flexible hose which also houses delivery mechanisms for a communications and entertainment packages including a computer that allows sending and receiving email, web browsing, digital telephone service, television and movies on demand. Billing for use of the module is accomplished electronically.

One disadvantage of the IdleAire System is seen primarily in its cost of implementation, due to the need to erect a gantry for positioning the modules and the requirement that real estate be dedicated solely for use of vehicles employing the system. Another disadvantage of the IdleAire System is seen in the fact that the modules are mounted at a substantial height above ground level. When repairs or maintenance are required, these must be performed either from a scaffold, a man-lift or other device that can raise and position maintenance personnel safely above ground-level.

What is needed is a system that serves to reduce emissions while an over-the-road vehicle is parked during an operator's rest or down time and which does not require additional capital expense by the vehicle owner. Benefit may also be found in providing an auxiliary heating, cooling and ventilation unit that does not require the erection of a superstructure for positioning the system above the vehicle. Additional advantage may also be found in providing an auxiliary heating, cooling and ventilation unit that does not require the dedication of parking spaces solely for users of the system only but rather offers the flexibility of allowing users as well as non-users of the system to park in any selected parking spot while having the system locatable at any parking spot. In addition advantage may be found in elimination of a superstructure or gantry and the adoption of a mobile modular auxiliary heating, cooling and ventilation unit that permits easy removal of the auxiliary system to a shop or other maintenance location wherein repair or maintenance personnel may work at ground level without interruption of the maneuvers of vehicles in the parking area, and without the need for a scaffold, man-lift or other device that can raise and position maintenance personnel safely above ground-level.

Therefore an object of the present invention is to provide an alternative system for reducing emissions when the over-the-road vehicle is parked during an operator's rest or down time and which does not require additional capital expense by the vehicle owner. Another object of the present invention is to provide an auxiliary heating, cooling and ventilation unit that does not require the erection of a superstructure for positioning the system above the vehicle. Yet another object of the present invention is to provide an auxiliary heating, cooling and ventilation unit that does not require the dedication of parking spaces solely for users of the system but rather offers the flexibility of allowing users as well as non-users of the system to park in any selected parking spot while having the system locatable at any parking spot. An additional object of the present invention is to eliminate the need for a superstructure or gantry for an auxiliary heating, cooling and ventilation unit that allows repair or maintenance at ground level.

SUMMARY OF THE INVENTION

The present invention is directed to an auxiliary vehicle rest station that is configured so that at least a portion of the device is positionable beneath the vehicle during use providing auxiliary heating, ventilation and air conditioning services for use by over-the-road trucks or other vehicles. The auxiliary vehicle rest station may also include access to a power supply capable of powering the various sub-systems of the station including an auxiliary air conditioning system. As used herein the term “air conditioning system” refers to heating, ventilation or air conditioning or cooling systems, as well as any combinations thereof. The auxiliary vehicle rest station may also include one or more data links for communication and entertainment systems. These may include links for internet, telephone services, video rental and streaming video.

In a preferred embodiment, the auxiliary vehicle rest station is configured so that at least a portion of the device is positionable beneath the vehicle, thereby reducing the footprint of the device that lies outside a footprint of the vehicle when the device is in use. In the preferred embodiment, the auxiliary vehicle rest station is configured for wheeled transport such that the device is positioned against the vehicle once the vehicle is parked. Preferably one or more of the wheels are lockable so that the auxiliary vehicle rest station may be held in position so as to remain substantially stationary during use. Additionally, the auxiliary vehicle rest station may include drive means adapted for advancing the device to and from a location proximate to the vehicle that will utilize the device.

The auxiliary vehicle rest station also includes a boom that extends or projects from the caddy to a height of a vehicle window. As such, the auxiliary vehicle rest station may also include a boom lift adapted for raising or projecting the boom. The boom is adapted so that an upper segment of the boom is substantially sealable with a window located on a body surface of the vehicle to accommodate an efficient introduction of conditioned air to the cab of the truck.

In one embodiment of the invention the auxiliary vehicle rest station is positioned with respect to the vehicle such that a compressible boot surrounding the boom outlet forms a substantially air flow free seal about a window, and site power is connected to the auxiliary vehicle rest station to power the heating, ventilation, air conditioning systems of the auxiliary vehicle rest station to be used by the vehicle.

In another embodiment of the present invention a power supply may include one or more power storage devices, for example lithium ion batteries. The power storage devices may be charged at a separate charging station or may alternately be charged by an onboard power generation means. The onboard power generation means may include a hydrogen fuel cell. Alternately, the onboard power generation means may include a small form factor internal combustion engine with attached generation device.
