(E) BACKGROUND OF THE INVENTION

(1) Field of the Invention.

The present invention is related to portable coolers. More specifically, this invention is a portable cooler that can be used in all terrains, arid that has advanced features.

(2) Background of Invention.

Portable cooler chests have beef) used for many years to transport food, liquids, ice, environmental samples* human tissues, or any items that need to remain heated or cooled during transportation. Some portable cooler chests are used on job sites for sample storage, in the medical industry for tissue transport, and in households for hauling food and beverages to picnics, beaches, and trips in a vehicle. Cooler chests are typically constructed with a lid. These chests are insulated on the walls, floor, and lid. Some traditional coolers were constructed with a metallic outer insulation shell, but the majority of coolers manufactured today are generally made from plastics. While portable cooler chests are known for their ability to maintain perishable items for long periods of time, their drawbacks include having only a single compartment; that can contain either solely hot or solely cold items. Also, any wet materials could leak or spill onto d ry materials in the single compartment. Drawbacks to a portable cooler are the combination of weight, hauling distance, and terrain Over which the cooler is to be towed. The larger the cooler's internal volume. the more Hems it can hold, and, therefore, the more difficult it witl be to transport. For example, a large cooler chest containing ice and canned or bottled beverages may require more than one person to carry the cooler. Furthermore, if the carriers have to traverse loose soil, sand, rocks, or uneven terrain, the risk of losing footing or dropping the cooler is significantly increased. Prior art devices to address problems of transporting coolers include adding one or two pairs of wheels and a towing handle to improve mobility. However, there are problems with prior wheeled coolers. One problem with four-wheeled coolers Is that the wheels do not rotate when the cooler is turned, requiring the user to trft the front wheels up with a handle to turn the cooler, as if the cooler only had two rear wheels. If a heavily loaded cooler is pulled across loose sand or gravel, the front wheels sink into the loose ground, creating even more resistance. Prior art wheeled coolers also provide little to no ground clearance. This can cause the bottom of the cooler chest surface to drag along the ground over uneven terrain. This could damage the shell and insulation, and possibly drag earthen matter and debris along with the cooler.

Prior aft wheeled coolers may require that the wheels be oriented to different positions for carrying or moving. The wheel configurations provide little to no ground clearance for the bottom of a four-wheeled cooler or for the back of a two-wheeled cooler. Other designs have permanently fixed wheels that extend outward from the cooler, but these designs impede hand carrying, create wasted external space if packing the cooler in a vehicle with other items, and still create difficulty in pulling over uneven or soft terrain. Some prior art wheeled cooler chests provide for retracting) pivoting, or changeable wheels and towing handles, however these designs suffer from similar drawbacks of low ground clearance and haying additional movable joints on the wheels or axles that can malfunction due to sand, dirt, and rust as well as requiring additional steps to open and retract the wheeibase. Users wanting ease of use and convenience in a towable cooler would find these features undesirable. The wheels are also not built with materials and dimensions to avoid the difficulty in pulling over uneven or soft terrain. One design in United States adds four expandable and retractable wheels to use over sand and soft surfaces. This design requires numerous manual steps to prepare when expanding or retracting and are prone to mechanical failure from dirt, weeds, and debris entering and clogging the expandable wheels, the retractable spindles, and recess areas for each wheel. Further this device has low ground clearance, as mentioned above.

An additional problem with prior wheeled cooler chests that are towed on two permanent wheels is that the storage area is inadequate and inefficient when wheels are attached. If larger wheels are used, the wheels extend out from the cooler wails making the footprint of the entire chest larger, and if wheels are recessed into the cooler's rectangular footprint they are made smaller, causing the problems stated above. Traditional wheeled cooler chest designs also fail to account for tipping upright or backwards if the towing handle is accidentally turned loose while a user is towing the chest. Another design feature not included in prior wheeled coolers is accounting for the height and arm length of a person puiiingthe cooler chest The lack of a handle design and wheel design that incorporates the height of a person and dimensions of the cooler in order to maximize the internal volume while minimizing the space taken by the wheels is a problem with the prior art wheeled cooler chests.

Another drawback of prior cooler chests is a lack of adequate compartmentaiization. A user of a cooler may want to haul hot and cold food and drinks in the same cooler and have a dry compartment and wet compartment to separate ice or liquids in containers that could spilt from dry food such as bread. A cooler in United States uses compartments of an ice cooler section for holding ice and iced food and drink and a separate thermos inside a cooler chest A compartment above the ice cooler section is designated as storage; however, this compartment is in contact with the ice cooler section and could easily be subject to contact with ice, liquids, or food in the main compartment. Furthermore, there is no hot food compartment moreover, one that is thermally separated from the ice cooler section, Prior portable chests provide no ability to stage food items in a thermally intelligent manner to maximize the length of time hot foods stay hot and cold foods stay cold.
