1. Field of the Invention
This invention relates generally to thermally insulated enclosures, and more particularly to systems for mounting thermally insulated enclosures.
2. Description of the Background Art
There has long been a high demand for portable insulated containers such as, for example, coolers, food and beverage containers, water coolers, lunch boxes, etc. Such containers are frequently transported in highly dynamic and, therefore, unstable environments such as, for example, on off-road vehicles, boats, construction trailers, heavy construction equipment, etc. When transporting containers in such environments, it is almost always necessary that they be secured down in order to prevent any problems associated with tipping and/or sliding. Doing so typically entails securing the enclosure to a stable structure via some suitable fastener (e.g., elastic cord, rope, strap, etc).
Although tipping and sliding problems can be prevented by fastening the enclosure to a stable structure via mechanical fasteners, there are disadvantages to doing so. For example, the enclosure can only be secured in locations where there are available structures (e.g., eye bolt) for the mechanical fasteners to engage. Another disadvantage to the current solution is the inconvenience associated with having to make sure the enclosure is accompanied by the fastener. Not only is it inconvenient to always keep a fastener on hand, but it is also inconvenient to have to remember to secure the enclosure. For example, forgetting to secure lunchboxes down on work trailers is a very common problem that often results in it falling off while the trailer is moving. As another example, the current solutions also impose challenges on heavy equipment operators because they typically have to remain on the equipment for long periods of time and, therefore, have to keep their coolers nearby. This is problematic in that there are typically not very many convenient structures to which an enclosure can be mounted via fasteners.
In efforts to alleviate the aforementioned problems, manufacturers have incorporated various types of slip preventative features into the design of many insulated enclosures. For example, friction promoting features (e.g., rubber, treads, etc) are often formed on the bottom surfaces of insulated containers.
Although friction promoting features can increase the amount of friction between the bottom surface of the container and the underlying surface, it is typically insignificant in such unstable environments.
What is needed, therefore, is an insulated enclosure that can be secured to a structure without additional fasteners. What is also needed is an insulated enclosure that can be secured to structures where no fastener structures are available. What is also needed is an insulated enclosure that is simpler to secure onto structures.
SUMMARYThe present invention overcomes the problems associated with the prior art by providing a thermally insulated enclosure having a magnet assembly that facilitates magnetic coupling of the insulated enclosure to a ferromagnetic structure. The invention facilitates, for example, securing ice chests, water coolers, and the like to vehicles and/or other equipment or structures.
In an example embodiment, a thermally insulated enclosure includes an insulated wall, an opening, and a magnet assembly. The insulated wall includes a first surface defining an interior of the enclosure and a second surface defining an exterior of the enclosure. The opening is closable and defines a passageway between the exterior of the enclosure and the interior of the enclosure. The magnet assembly is coupled to the insulated wall, and provides an attractive magnetic force sufficient to fixedly secure the thermally insulated enclosure to a ferromagnetic structure. Optionally, the attractive magnetic force of the magnet assembly is sufficient to fixedly secure the thermally insulated enclosure to a vertical surface of ferromagnetic structures. In some disclosed embodiments, the attractive magnetic force of the magnet assembly is sufficient to fixedly secure the thermally insulated enclosure to a vertical surface of a ferromagnetic structure when the thermally insulated enclosure is full of liquid.
In one example embodiment, the magnet assembly includes at least one magnet mounted to the second surface of the insulated wall (exterior of enclosure). In an alternate embodiment, the magnet assembly includes at least one magnet mounted to the first surface of the insulated wall (interior of enclosure), and the thermally insulated enclosure is an insulated bag. In another alternate embodiment, the magnet assembly includes at least one magnet mounted between the first surface of the insulated wall and the second surface of the insulated wall (within the insulated wall).
In an example embodiment, a portion of the insulated wall defines a bottom region of the thermally insulated enclosure, and the magnet assembly is disposed at the bottom region of the thermally insulated enclosure. In another example embodiment, a portion of the insulated wall defines a side region of the thermally insulated enclosure, and the magnet assembly is disposed at the side region of the thermally insulated enclosure. Optionally, the magnet assembly includes at least one magnet coupled to the side region of the thermally insulated enclosure and at least one magnet coupled to the bottom region of the thermally insulated enclosure.
In an example embodiment, the magnet assembly is removable from the thermally insulated enclosure. The magnet assembly includes a rigid support structure adapted to engage the exterior of the enclosure. At least one magnet is fixedly coupled to the rigid support structure, and a fastening device is coupled to the rigid support structure. The fastening device is operative to fixedly couple the insulated wall to the rigid support member. Optionally, the magnet assembly is adapted to universally mount objects to ferromagnetic structures.
In a particular embodiment, the rigid support structure is a plate having a top surface and an opposite bottom surface. The top surface is adapted to engage the exterior of the insulated wall, and the at least one magnet of the magnet assembly is fixedly attached to the bottom surface of the plate. In one example embodiment, the fastening device is a strap. In another embodiment, the rigid support structure is a molded structure formed around at least a portion of the at least one magnet.
Optionally, the thermally insulated enclosure is collapsible. For example, in one particular embodiment, the insulated enclosure is a bag. In another example embodiment, the insulated enclosure is a collapsible chest. The collapsible chest includes a removable insert that has an inner surface defining at least a portion of the interior of the thermally insulated enclosure. The thermally insulated enclosure includes a collapsible outer shell, which has an outer surface defining at least a portion of the exterior of the thermally insulated enclosure, and the collapsible outer shell is adapted to receive the removable insert. The removable insert and the collapsible outer shell form components of the insulated wall, and the magnet assembly is coupled to a portion the collapsible outer shell. Optionally, the portion of the collapsible outer shell coupled to the magnet assembly is formed by molding material directly around at least a portion of the magnet assembly.
In another example embodiment, the thermally insulated enclosure is rigid. The insulated wall includes a first rigid layer, a second rigid layer, and an insulation layer. The first rigid layer has an outer surface and an opposite inner surface. The outer surface of the first rigid layer defines the exterior of the thermally insulated enclosure. The second rigid layer has an outer surface and an opposite inner surface. The inner surface of the second rigid layer defines the interior of the thermally insulated enclosure. The insulation layer is sandwiched between the inner surface of the first rigid layer and the outer surface of the second rigid layer. The magnet assembly includes at least one magnet fixedly coupled to the outer surface of the first rigid layer. Alternatively, the magnet assembly includes at least one magnet disposed between the inner surface of the first rigid layer and the insulation layer. As another alternative, a portion of the first rigid layer is molded directly on at least a portion of the magnet assembly.
In yet another example embodiment, the thermally insulated enclosure is a container adapted to dispense potable liquids (e.g., a water cooler). A portion of the insulated wall defines a bottom region of the water cooler, and the magnet assembly is removably coupled to the bottom region of the water cooler. The magnet assembly is operative to fixedly mount the water cooler on horizontal surfaces of ferromagnetic structures. Alternatively, a portion of the insulated wall defines a side region of the water cooler, the magnet assembly is removably coupled to the side region of the water cooler, so that the magnet assembly is operative to fixedly mount the water cooler to a vertical surface of a ferromagnetic structure.
The insulated wall of the water cooler includes a first rigid layer, a second rigid layer, and an insulation layer. The first rigid layer has an outer surface and an opposite inner surface. The outer surface of the first rigid layer defines the exterior of the thermally insulated enclosure. The second rigid layer has an outer surface and an opposite inner surface. The inner surface of the second rigid layer defines the interior of the thermally insulated enclosure. The insulation layer is sandwiched between the inner surface of the first rigid layer and the outer surface of the second rigid layer.

The present invention overcomes the problems associated with the prior art, by providing a thermally insulated enclosure including a magnet assembly for mounting the enclosure to ferromagnetic structures. In the following description, numerous specific details are set forth (e.g., type of ferromagnetic structure, magnet geometry, fasteners, etc.) in order to provide a thorough understanding of the invention. Those skilled in the art will recognize, however, that the invention may be practiced apart from these specific details.

Cooler 100 includes an insulated wall 110, an insulated lid 112, and a magnet assembly 114 (visible in
Those skilled in the art will recognize that cooler 100 provides several advantages over prior art insulated enclosures. For example, cooler 100 can be secured to ferromagnetic structures without the need for mechanical fasteners. This is beneficial in that it not only eliminates the need always have mechanical fasteners on hand, but also enables cooler 100 to be mounted to structures (i.e. flat walls) that do not have physical features for mechanical fasteners to engage. Furthermore, cooler 100 is self mounting thus eliminating the process of manually fastening it to a suitable structure. This is not only convenient, but also ensures that cooler 100 remains secure in situations such as, for example, when left on the tailgate of a truck, toolbox, trailer, etc. As another example, cooler 100 can be very useful for heavy equipment operators because it can be placed at almost any location on the equipment without the risk of falling off during operation.
Insulated wall 110 further includes a first rigid layer 202, an insulation layer 204, and a second rigid layer 206. First rigid layer 202 defines the exterior surfaces of insulated wall 110. More specifically, first rigid layer 202 defines a bottom exterior surface 208 of bottom wall 116 and four side exterior surfaces 210 of side walls 118. Insulation layer 204 is disposed between first rigid layer 202 and second rigid layer 206 so as to impede heat transfer through wall 110. Second rigid layer 206 defines the interior surfaces of insulated wall 110 including a bottom interior surface 212 of bottom wall 116 and four side interior surfaces 214 of side walls 118. Furthermore, second rigid layer 206 is coupled to first rigid layer 202 near the top of sidewalls 118 such that insulation layer 204 is enclosed therebetween.
Insulated lid 112 further includes a first rigid layer 216 and an insulation layer 218. First rigid layer 216 defines an exterior surface 220 of lid 112 and, therefore, the contour of handle 122. Accordingly, first rigid layer 216 of lid 112 and first rigid layer 202 of insulated wall 110, together, define the exterior surface of cooler 100. Insulation 218 is coupled to the interior surface of first rigid layer 216 so as to impede heat transfer through lid 112. When lid 112 is closed, insulation layer 218 covers and insulates opening 200 such that the interior of cooler 100 is completely enclosed with insulation on all six sides.
Magnet assembly 114 includes a plurality of magnets 222 coupled to bottom wall 116 of insulated wall 110. In this particular embodiment, magnets 222 are imbedded directly into first rigid layer 202 by some suitable means. For example example, first rigid layer 202 could be a plastic structure that is formed by molding plastic material directly over magnets 222.
