When spending a day at the beach, a family or group generally has many items that they wish to take with them to the beach. Such items may include towels, chairs, umbrellas, games, lotions and sun screen products, food and beverages, and the like.
It is often the situation that transporting the desired items to the beach is inconvenient and cumbersome. Indeed, it often requires many trips back and forth from a car or hotel room to a particular spot on the beach.
Various mobile devices are known that can aid in such transport. However, such known devices generally comprise either a wheeled cart for transporting non-perishable items, such as towels, chairs, etc., or a wheeled cooler for transporting perishable items, such as food and beverages. Such known devices do not generally include a mobile device that is capable of transporting both non-perishable items as well as perishable items, and such known devices generally do not include a sufficient capacity to transport all, or even most, of the items that a family or group will need for a day-long outing at the beach in a single trip. Rather, a person generally still has to make multiple trips from the originating location, e.g., car or hotel room, to the destination location, e.g., spot at the beach.
An additional drawback to known devices is that such devices generally require a large amount of storage space when not used. Such mobile devices are typically stored in a garage, storage shed or closet when not in use because of the bulk of the devices. Further, these mobile devices take up relatively large amounts of space whenever they are transported for use. This is particularly disadvantageous when the mobile devices are packed into the family car when going on the family vacation at the beach. Because they are so large and bulky, they tend to consume a large portion of the available space in the car, thereby limiting the other items that can be taken on the vacation. In addition to being disadvantageous for consumers, such devices also are less desirable to retailers, who have limited shelf space on which to display goods for sale.
One of the known devices is disclosed in U.S. Pat. No. 6,474,097 to Treppedi et al., which is hereby incorporated herein by reference. The mobile carrying device of Treppedi comprises a cooler that includes ski runners and wheels in combination to aid in mobility of the cooler. It also includes an extendable, pivoting handle that may be retracted and stored adjacent the cooler. Cargo nets are attached to the top and side of the cooler for storage of supplies such as towels, plates and cups. The mobile cooler also includes a retainer attached to a side of the cooler for holding an umbrella.
Another known device is disclosed in U.S. Pat. No. 6,176,499 to Conrado, which is hereby incorporated herein by reference. The mobile carrying device of Conrado is a mobile cooler that includes a cooler body with wheels and a pivoted towing handle having two grips for users of varying heights. The underside of the cooler lid has a recess with a cover panel for storing items separately from other items in the cooler. The cooler includes a table assembly operable independently of the cooler lid so that the table may be utilized whether the lid is open or closed. The cooler also includes retractable bungee cords for securing items to the cooler.
The devices of Treppedi and Conrado are exemplary of the shortcomings of the known devices previously discussed herein. Specifically, these devices do not provide sufficient capacity for transporting the number of items to be used for a family or group during a day at the beach. Furthermore, these devices do not have a storage configuration that is smaller in volume than their use configuration.
Collapsible insulated containers also are known which may be utilized for storage of perishable items and that have a storage configuration that is smaller in volume than their use configuration. Such known devices are disclosed, for example, by U.S. Pat. Nos. 3,347,060; 4,085,785; 4,091,852; and 4,612,781, each of which is hereby incorporated herein by reference. However, such known devices do not include design features that aid in mobility of the devices, let alone design features that aid in the transport of non perishable items such as towels, chairs, umbrellas, games, lotions and sun screen products.
Accordingly, a need exists for a mobile device that can be used to transport both non-perishable and perishable items and that has enough capacity to transport a sufficient amount of such items for a day at the beach. Moreover, a need exists for a mobile device that is capable of transporting a relatively large number of both perishable and non-perishable items and that has a storage configuration that is substantially smaller in dimensions than its use configuration.

Other aspects and features are set forth in the '225 application, which aspects and features are incorporated by reference herein.
In addition to the aforementioned aspects and features of the present invention, the present invention further includes the various possible combinations and permutations of such aspects and features.
Further aspects, features, embodiments, and advantages of the present invention will become apparent from the following detailed description with reference to the drawings, wherein:
As a preliminary matter, it will readily be understood by one having ordinary skill in the relevant art (“Ordinary Artisan”) that the present invention has broad utility and application. Furthermore, any embodiment discussed and identified as being “preferred” is considered to be part of a best mode contemplated for carrying out the present invention. Other embodiments also may be discussed for additional illustrative purposes in providing a full and enabling disclosure of the present invention and may or may not be a preferred embodiment. Moreover, many embodiments, such as adaptations, variations, modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments described herein and fall within the scope of the present invention.
Accordingly, while the present invention is described herein in detail in relation to one or more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the present invention, and is made merely for the purposes of providing a full and enabling disclosure of the present invention. The detailed disclosure herein of one or more embodiments is not intended, nor is to be construed, to limit the scope of patent protection afforded the present invention, which scope is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.
Thus, for example, any sequence(s) and/or temporal order of steps of various processes or methods that are described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal order, the steps of any such processes or methods are not limited to being carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and orders while still falling within the scope of the present invention. Accordingly, it is intended that the scope of patent protection afforded the present invention is to be defined by the appended claims rather than the description set forth herein.
Additionally, it is important to note that each term used herein refers to that which the Ordinary Artisan would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used herein—as understood by the Ordinary Artisan based on the contextual use of such term—differs in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the Ordinary Artisan should prevail.
Furthermore, it is important to note that, as used herein, “a” and “an” each generally denotes “at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. Thus, reference to “a picnic basket having an apple” describes “a picnic basket having at least one apple” as well as “a picnic basket having apples.” In contrast, reference to “a picnic basket having a single apple” describes “a picnic basket having only one apple.”
When used herein to join a list of items, “or” denotes “at least one of the items,” but does not exclude a plurality of items of the list. Thus, reference to “a picnic basket having cheese or crackers” describes “a picnic basket having cheese without crackers”, “a picnic basket having crackers without cheese”, and “a picnic basket having both cheese and crackers.” Finally, when used herein to join a list of items, “and” denotes “all of the items of the list.” Thus, reference to “a picnic basket having cheese and crackers” describes “a picnic basket having cheese, wherein the picnic basket further has crackers,” as well as describes “a picnic basket having crackers, wherein the picnic basket further has cheese.”
Referring now to the drawings, in which like numerals represent like components throughout the several views, preferred embodiments of the present invention are next described. The following description of preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
The base 20 includes a bottom 24, a first end 26, a second end 28, and a top surface 30. The base 20 includes a length defined by the distance between the first end 26 and the second end 28. The base 20 further includes a container receiving recess 32 and an extension portion 34.
The peripheral wall 38 has a front end 40, which is disposed at the first end 26 of the base 20. The front end 40 of the peripheral wall 38 defines a handle recess 42 for receiving and retaining the handle 16 at a first location. In the illustrated embodiment, the handle recess 42 is a pair of vertically-oriented tubular recesses that extend downward into the top of the front end 40 of the peripheral wall 38. The extension portion 34 of the wheeled platform base 20 extends below and beyond the insulated container 14 toward the second end 28 of the base 20 from the container receiving recess 32. The extension portion 34 extends between one-half and one-quarter of the length of the base 20. In the illustrated embodiment, the extension portion 34 is fixedly mounted to the container receiving recess 32. However, the Ordinary Artisan will understand that, alternatively, the extension portion 34 may be mounted for movement relative to the container receiving recess 32, including pivotable movement and/or linear sliding movement. Furthermore, the Ordinary Artisan will understand that the base 20 may not include the extension portion 34. In such embodiment, the second end 28 of the base 20 is disposed adjacent the container receiving recess 32. Additionally, in such embodiment, the cooler 10 does not include the retaining member 18.
The extension portion 34 extends from the container receiving recess 32 at an elevation proximate a bottom 60 of the insulated container 14. The extension portion 34 also extends downwardly at an incline to an elevation below the bottom 60 of the insulated container 14, which generally corresponds to a surface on which the cooler 10 rests when stationary. The extension portion 34 includes a surface upon which additional items may be supported for transport.
The extension portion 34 may be trapezoidal in form with a first side 44 in abutting arrangement with the container receiving recess 32 and a second side 46 disposed a fixed distance from and substantially parallel to the first side 44. Two additional sides 48 extend between the first side 44 and the second side 46 to form the trapezoidal shape of the extension portion 34. The second side 46 of the extension portion 34 has indentations formed therein defining a handgrip for receipt of the fingers of a user.
The retaining member 18 comprises two leg members 72 arranged in parallel relation to one another, each having a first end and a second end. The leg members 72 are connected to one another at their first ends by a cross-beam 74 that extends orthogonally between the two members 72. The cross-beam 74 includes indentations in the surface thereof defining a handgrip for receipt of the fingers of a user. In the upright, protracted position shown in
As best seen in
The insulated container 14 may be used as a cooler when uncoupled from the wheeled platform 12 as shown in
In the transport configuration, the bladder 54 is in an inflated condition, wherein the enclosed space is substantially filled with air. Air is received into the enclosed space through a valve 70 disposed in the outer wall 64 of the bladder 54. In the illustrated embodiment, the valve 70 is disposed near the first end 26 of the base 20. As such, the valve 70 is near the handle 16 when the travel cooler 10 is in the transport configuration. When the enclosed space is filled with air, the air creates enough rigidity that the walls of the bladder 62, 64 are generally upstanding. Such air also serves to insulate the interior space of the container 14, thereby facilitating the container's use as a cooler. In the inflated condition, the insulated container 14 preferably sized to have a capacity to hold sixty-two quarts in the insulated, interior space of the container 14.
The rim 56 is disposed on the upper edge wall 66 of the bladder 54 and connected thereto as further described hereinbelow. The rim 56 may be generally oval shaped with an opening in the center allowing items to be placed inside the container 14, while the lid 58 is similarly shaped to correspond with the rim 56. The lid 58 is connected by hinge to the rim 56 such that the lid 58 may be opened and closed without fully detaching the lid 58 from the container 14. The rim 56 and lid 58 are comprised of a rigid, non-inflatable material and therefore do not collapse when air is evacuated from the enclosed space of the bladder 54. The lid 58, the rim 56 and the retaining member 18, which is described hereinabove, are preferably durable and rigid and are formed in one or more molding processes. The molding processes may include injection molding, rotational molding, and/or blow molding. Furthermore, the lid 58, rim 56 and retaining member 18 may be integrally formed or separately formed and thereafter connected together.
The handle 16 further comprises a pair of catch assemblies 84, one disposed within each of the extension portions of the handle 78. The catch assemblies 84 are identical in design and operation, and thus only one will be described herein. A catch assembly 84 comprises a rod 86, having a first end 88 and a second end 90, a catch 92 disposed at the first end 88 of the rod 86 and a ball 94 disposed at the second end 90 of the rod 86. The rod 86 is substantially enclosed within the extension portion of the handle 78. A portion of the catch 92 is disposed within the extension portion 78, and another portion of the catch 92 extends through the first opening 82. The second end 90 of the rod 86 extends through a second opening 96 disposed at the proximal end of the extension portion 78 and is connected to the ball 94, which is disposed outside the extension portion 78. When the ball 94 is pulled by a user, the rod 90 actuates the catch 92, thereby moving the catch 92 such that the portion of the catch 92 that extends through the first opening 82 is pulled inwardly into the extension portion 78. When the ball 94 is released, a portion of the catch 92 returns to being extended through the first opening 82. The catch 92 is spring-biased.
Specifically, when the travel cooler 10 is in its storage configuration, the insulated container 14 is collapsed, rather than inflated as it is in its transport configuration. More particularly, the bladder 54 of the insulated container 14 is collapsed. The enclosed space between the inner wall 62 and outer wall 64 is substantially evacuated of air, and thus the flexible walls 62, 64 of the insulated container 14 have no supporting force to hold them upright. When the bladder 54 is collapsed, the lid 58 and the rim 56 are received into the container receiving recess 32. The depth of the container receiving recess 32 is such that the lid 58 and rim 56 fit substantially within the recess 32.
Further, the retaining member 18 is folded inwardly toward the insulated container 14 in a retracted position such that it fits substantially adjacent the extension portion 34 of the base 20 with no portion thereof protracting from the base 20. When the retaining member 18 is in the retracted position, a user may extend his hand or fingers through the trapezoidal opening formed in the extension portion 34 and utilize the second side 46 as a handle for lifting or otherwise manipulating of the travel cooler 10, which feature may be particularly useful when the cooler 10 is not used and in its storage configuration.
In addition, in the storage configuration, the handle 16, which is completely detachable and removable from the base 20, is removed from the handle recess 42 and is placed in the handle receiving area 52 of the base 20. As perhaps best shown in
Returning to
The insulated container 14 is coupled to the base 20 by coupling components. When the insulated container 14 is coupled to the base 20, the coupling components are disposed in interlocking engagement with one another; thus, the insulated container 14 is securely coupled to the wheeled platform 12 for safe transportation on the wheeled platform 12, i.e., the insulated container 14 is protected from falling off of the base 20.
In the illustrated embodiment, the coupling components are snaps. More particularly, snap buttons 99 are disposed on the bottom wall 60 of the insulated container 14, that are received into corresponding snap sockets 100 in the base 20 to connect the insulated container 14 to the base 20. Such snap sockets 100 are disposed in the top surface 30 of the base 20. The snap buttons 99 may be evenly spaced from one another proximate a perimeter of the bottom wall 60 of the container 14.
In use, when the bottom portion 36 of the container 14 is placed in the container receiving recess 32 of the wheeled platform 12, the snap buttons 99 are received into the mating snap sockets 100 thereby coupling the container 14 and the base 20. If it is desired to uncouple and remove the container 14 from the base 20, a user may pull the container 14 upwardly thereby forcibly disengaging the snap buttons 99 from the snap sockets 100.
The upper edge wall 66 of the bladder 54 is also connected to the rim 56 with coupling components. In the illustrated embodiment, the coupling components are snaps. More particularly, snap sockets 104 are evenly spaced around the upper edge wall 66 of the bladder 54 and mating snap buttons are evenly spaced in corresponding arrangement around the underside of the rim 56 such that the snap sockets 104 and snap buttons mate to connect the rim 56 to the bladder 54. The ability to easily uncouple the bladder 54 from the rim 56 and the wheeled platform 12 is an advantage of the present invention. Such detachability makes it possible to separately replace the bladder 54, the rim 56 and the wheeled platform 12 in the event that one of these components is damaged, as well as to permit the various components to be washed more easily. While not illustrated herein, the Ordinary Artisan will understand that a handle or strap further may be provided on the insulated container 14 for transport of the container 14 when it is uncoupled from the wheeled platform 12.
The bottom wall 60 of the bladder 54 has a drain conduit 108 disposed therein for removal of water or other liquids from the insulated interior space of the insulated container 14. Such liquids may be drained from the insulated container 14 both when the insulated container 14 is coupled to the wheeled platform 12 and when the insulated container 14 is uncoupled from the wheeled platform 14.
The drain conduit 108 includes an interior portion 110 and an exterior portion 112. The interior portion 110 extends through the bottom wall 60 of the insulated container 14 and provides a passageway to drain liquid from the insulated container 14. The exterior portion 112 includes a plug to block the flow of liquid through the interior portion 110. The drain conduit 108 is disposed in the bottom wall 60 of the container 14 and thus remains attached to the container 14 when the container 14 is uncoupled from the wheeled platform 12.
A corresponding drain conduit opening 114 is formed in the container receiving recess 32 for receipt of the exterior portion 112 of the drain conduit 108 therein for removal of liquids from the container 14 when the container 14 is coupled to the wheeled platform 12. When the insulated container 14 is coupled to the wheeled platform 12, the exterior portion 112 of the drain conduit 108 extends through the wheeled platform base 20 via the drain conduit opening 114 for easy access by a user.
In order to remove liquids from the insulated interior of the insulated container 14, a user simply pulls the exterior portion 112 of the drain conduit 108, which opens the drain conduit 108 and allows liquids to flow there through. A user may close the drain conduit 108 when the desired amount of liquid has been drained from the insulated container 14.
As described previously, in order to inflate the bladder 54 of the insulated container 14, air is received into the bladder enclosed space. A hand pump 120 may be utilized to introduce such air into the enclosed space. The hand pump 120 is a conventional dual action hand pump with two mating cylinders 122 and a nozzle 124 disposed at one end. The nozzle 124 is sized to be coupled with the valve 70 such that air may be introduced into the bladder 54 utilizing the hand pump 120. Because the hand pump 120 is a dual action hand pump, air is introduced into the bladder 54 when the hand pump is both pulled and pushed. Accordingly, the bladder 54 can be inflated relatively quickly by hand.
The travel cooler lid 58 defines a pump receiving recess 126 in the exterior thereof for retention of the hand pump 120 when it is not in use.
Together, the shape of the pump receiving recess 126 and the foam disk 128 secure the hand pump 120 in the lid 58 when the hand pump 120 is not in use. A user simply pulls the nozzle end of the hand pump 120 to remove the hand pump 120 from the pump receiving recess 126. To return the hand pump 120 to the recess 126, a user couples the mating end of the hand pump 120 with the foam disk 128 and then snaps the hand pump 120 into place in the recess 126. In the present embodiment, the hand pump 120 is retained in the lid 58; however, the Ordinary Artisan will understand that the hand pump 120 may be received and retained anywhere on the travel cooler 10 where sufficient space is available.
The spring-biased catches 92 secure the handle 16 in both the stored position and the upright position; therefore, in order to move the handle 16 from the stored position to the upright position, the catch assemblies 84 are actuated. To actuate such assemblies 84, a user pulls the balls 94 of the catch assemblies 84 thereby moving the catches 92 inwardly into the extension portions of the handle 78. When the catches 92 are disposed within the extension portions 78, the handle 16 may be removed from the handle receiving area 52 by sliding it out of the handle receiving area 52.
To place the handle 16 in the upright position, the user arranges the handle 16 such that the bent portion 80 is oriented toward the user. In this arrangement, the balls 94 of the catch assemblies 84 are easily accessed by the user. The user pulls the balls 94, which allows the extension portions 78 to be slid into the handle recess 42. Once the distal ends of the extension portions 78 have been inserted into the handle recess 42, the user may release the balls 94 and continue sliding the extension portions 78 through the handle recess 42. When the first openings 82 of the extension portions 78 have passed through the handle recess 42, a portion of the catches 92 extend outwardly through the first openings 82 thereby securing the handle 16 from sliding out of the handle recess 42. The handle 16 is secured in the upright position until a user actuates the catch assemblies 84 by pulling on the balls 94 of the catch assemblies 84 and removes the handle 16 from the handle recess 42. In the upright position, the handle 16 may be used to easily pivot and roll the travel cooler 10 from one location to another in similar fashion to how a hand truck may be pivoted and rolled.
As discussed previously herein, the bladder 54 collapses into the container receiving recess 32 when air is evacuated from the bladder enclosed space. Further, the rim 56 and lid 58 fit substantially within the container receiving recess 32 such that the height of the cooler 10 in the storage configuration is essentially the same as that of the peripheral wall 38 of the container receiving recess 32. As such, the cooler 10 occupies minimal space when it is in the storage configuration and thus lends itself to being stacked for storage or display.
Referring to the stacking configuration of
The stacking pairs 132 are further arranged one on top of the other, with the lid 58 of the top cooler 10 in the bottom stacking pair 132 being in adjacent contact with the lid 58 of the bottom cooler 10 in the top stacking pair 132. The stacking pairs 132 are also arranged in an alternating arrangement, with all of the bottom coolers 10 of the stacking pairs 132 being disposed in one direction and all of the top coolers 10 in the stacking pairs 132 being disposed in the opposite direction.
Alternatively, a stacking pair 132 may comprise a bottom cooler 10 and a top cooler 10 arranged such that the lid 58 of the bottom cooler 10 is in abutting engagement with the lid 58 of the top cooler 10. In this alternative stacking pair arrangement, the top cooler 10 has been turned up side down.
In operation, the travel cooler 10 of the present invention may be utilized to transport items from one location to another. When the travel cooler 10 is in the transport configuration, it is ideal for carrying such items. Perishable items may be placed in the insulated container 14 when the container 14 is in the inflated condition. In order to inflate the insulated container 14, air is hand pumped into the bladder enclosed space. Specifically, a user removes the hand pump 120 from the pump receiving recess 126 and couples the hand pump nozzle 124 to the valve 70. The user then operates the dual action hand pump 120 by moving the cylinders 122 in and out in conventional hand pumping action. Once the insulated container 14 has been inflated, the hand pump 120 is removed from the valve 70 and the valve 70 is closed to insure that no air escapes from the space. The hand pump 120 may then be replaced in the pump receiving recess 126.
Non-perishable items, e.g., folded beach chairs, towels, and the like, may be placed in a cargo receiving area 130 bounded by the retaining member 18, the extension portion 34, and the insulated container 14. In addition, because the lid 58 is substantially planar, items may also be placed on top of the lid 58 for transport. Bungee cords may strapped to the cooler 10 and utilized to stabilize such items for transport.
A loaded travel cooler 10 may be easily moved from one location to the next. A user simply grasps the handle 16, tilts the cooler 10 back toward the user using the wheels 22 as pivot members, and begins either pushing or pulling the cooler 10 to the desired location. The extension portion of the cooler 34 is lifted off the ground in a tilted position such that the extension portion 34 does not hinder movement of the cooler 10. During transport, items contained within the cargo receiving area 130 are securely maintained therein by the cooler configuration. When a user arrives at his destination, he simply tilts the cooler 10 back to rest stably on the ground.
Once a user has arrived at the desired location and removed items from the cargo receiving area 130, the retaining member 18 may be folded down or the handle 16 may be placed in the stored position. In addition, the insulated container 14 may be removed from the wheeled platform 12 if so desired.
When a user desires to store the travel cooler 10, liquid may be removed from the container 14 by opening the drain conduit 108 and air may be removed from the bladder space by utilizing the valve 70. More particularly, a user squeezes the valve 70 to open the valve and evacuate air from the enclosed space within the bladder 54. The walls of the container 62, 64 collapse when air has been evacuated from the enclosed space there between. Once the bladder 54 is collapsed, the container lid 58 and rim 56 fit within the container receiving recess 32. The retaining member 18 may be folded to the stored position and the handle 16 moved to the stored position. In this storage configuration, the travel cooler 10 may be easily stored or may be stacked for retail display.
The travel cooler 10 of the present invention is advantageous over known wheeled coolers because the present invention provides a travel cooler 10 that may easily transport both perishable and non-perishable items from one location to another and may be easily stored because the dimensions of the travel cooler 10 may be significantly reduced for storage thereof. A further advantage of the travel cooler 10 is that the insulated container 14 may be uncoupled from the wheeled platform 12 thereof for separate use or for replacement in the event of damage. It is a further advantage of the travel cooler 10 that the cooler 10 is designed to have a minimum amount of failure points. For example, the handle 16 is not connected to the wheeled platform 12 with a hinge that could fail but rather is removably attached to the wheeled platform 12 to provide a more sturdy, reliable attachment point. For components that may be more susceptible to damage, such as the bladder 54, the design makes it possible to replace such components, if damaged. In addition, the length and positioning of the handle 16 provide an advantage for a user when the cooler 10 is being transported by allowing the user to comfortably roll the cooler 10 on its wheeled platform 12 without having to bend over to grab and pull the handle 16 while transporting the cooler 10.
A second embodiment of the present invention is shown in
A telescoping handle of the cooler 1100 has a piston portion 1110 and a cylinder portion 1112 that together are utilized in inflating the container 1108. The telescoping handle pivots about a hinge point 1114 toward the rigid lid 1116 of the container 1108 for minimizing the overall outer dimensions of the cooler 1100 when the storage configuration is obtained (
A cargo receiving area 1118 is defined between the container 1108, the platform 1102, and a retaining member 1120. The cargo receiving area 1118 is useful for receiving an item for ease in transport such as, for example, a folding chair, a shade umbrella, a beach blanket and towels, fishing equipment, and/or other gear. This is especially convenient for transporting items from a car to a sunny spot on the beach. The retaining member 1120 pivots toward the lid 1116 for minimizing the overall outer dimensions of the cooler 1100 when the storage configuration is obtained (
A third embodiment of the present invention is shown in
A telescoping handle 1212 serves as a guide handle in directing, pushing and pulling the cooler about in its travels. A cargo receiving area 1218 is defined between the container 1208, the platform 1202, and a retaining member 1220. The retaining member 1220 pivots toward the lid 1216 for minimizing the overall outer dimensions of the cooler 1200 when the storage configuration is obtained (
