Description




FIELD OF THE INVENTION




This invention relates to portable coolers.




BACKGROUND OF THE INVENTION




Portable coolers are seeing an increase in popularity, particularly as their portability has been enhanced. They are, of course, used in various outings, including picnics, as well as at parties and the like to maintain food and beverages at a desired temperature, usually, but not always, below the temperature of the ambient. To enhance the versatility of such coolers, many are made with wheels and a handle for pulling the cooler on the wheels.




Typical wheeled coolers perform their intended function of providing portability, but in many instances, are aggravating to use. Because, for example, compactness is a desirable feature in such a cooler, the handles may be relatively short with a consequence that the user, grasping the handle to pull the cooler, may feel the cooler literally nipping at the user's heels because the cooler must be towed directly behind the user.




Moreover, conventional handle designs do not take into account the stature of users of a wheeled cooler. A long handle suitable for a person of tall stature may make it impossible for a person of short stature, such as a child, to tow a cooler by the handle without the cooler dragging on the underlying terrain, when the cooler is provided with only two wheels.




Still another difficulty arises where the towing handle is freely pivoted to the cooler. In such a case, if the person pulling the cooler stops relatively abruptly, the momentum of the cooler may cause it to continue to move forward. Because the handle is pivoted to the cooler and free to move, in a typical case, to or even past a purely vertical position, the cooler may coast into the legs of the user.




Many coolers have flat upper surfaces on their lids or covers which may be used as a table surface. However, when the lid or cover is being used as a table surface, it is impossible to achieve access to the interior of the cooler without first taking all objects off of the lid of the cooler. Furthermore, where coolers are taken on outings away from a residence, it is not uncommon that the user of the cooler will be bringing other objects as well. For example, if the user were going to the beach, lawn chairs and/or blankets and/or towels would typically be brought along. Handling these items in addition to the cooler makes transportation of the ingredients of the beach party a difficult chore.




A further problem with conventional coolers occurs when one is transporting items in the cooler that are intended to remain dry and/or are subject to crushing. As is well known, it is typical to fill the bottom of a cooler with beverage cans or bottles along with ice to maintain the items at a cold temperature. Eventually the ice melts and if other food items that are not intended to be wetted are in the cooler, the water from the ice may saturate the food items and make them unpalatable. Moreover, such food items as, for example, sandwiches, even if placed in sealed plastic bags or the like, are subject to crushing as heavy beverage cans or bottles shift within the cooler cavity.




The present invention is directed to providing a cooler that meets one or more of the above concerns.




SUMMARY OF THE INVENTION




It is the principal object of the invention to provide a new and improved portable cooler.




According to one facet of the invention, a cooler is provided that includes a cooler body of insulating material and which has an internal cavity having an upper access opening for receipt of items whose temperature is to be maintained at a predetermined level. A cover is provided for the access opening and a first hinge pivots the cover to the cooler body. A table element that includes edges and a lower table surface overlies the cover. A second hinge pivots one of the edges of the table element to one of the cover and the body. A leg is provided and overlies the cover. The leg has a length generally the same as the height of the body and a third hinge pivots the leg to the table element oppositely of the table surface and at a location spaced from the second hinge.




As a consequence, the table element resides compactly on top of the cover during transportation of the cooler and yet may be opened with the leg unfolded to provide a table surface adjacent to the cooler body. The use of the separate table surface enables one to use the table surface and yet achieve access to the interior of the cooler body by opening the cover without first clearing the table surface.




In a preferred embodiment, the first and second hinges respectively pivot the cover and the table about a common pivot axis.




In one embodiment, the table element includes a recess oppositely of the table surface and the leg nests in the recess.




A preferred embodiment of the invention includes a hook at an edge of the table element and in the table surface at a location spaced from the second hinge. The hook may be used to support a waste receptacle such as a plastic garbage bag.




A preferred embodiment includes stops on the table element for engaging the leg limit movement of the leg from a stored position nested within the recess to an extended position approximately 90° therefrom.




According to another aspect of the invention, a cooler is provided which includes a cooler body and lid having an internal cavity for receiving items whose temperature is to be maintained at a desired level. A pulling handle is attached to the cooler body and lid and wheels are disposed on the cooler body and lid so that the cooler body and lid may be pulled over the underlying terrain. A pair of horizontally spaced openings are disposed in the cooler body and lid and an elongated bungee cord having opposed ends is provided. The ends of the bungee cord are received in and restrained in a respective one of the openings. As a consequence, other non-cooler items to be transported, such as chairs, blankets or the like, may be placed on the cover and lid and secured thereto through the use of the bungee cord, making it necessary only to pull the cooler rather than pull the cooler and carry the additional items.




In a preferred form of this facet of the invention, the cooler body and lid include an upwardly opening cooler body and a lid element pivoted thereto. The openings receiving the ends of the bungee cord are located in the lid element.




Preferably, the bungee cord is in tension and even more preferably, a groove extends between the openings so that the tension in the bungee cord normally causes the bungee cord to retract and nest in the groove to be out of the way except when being used to secure other items to the cooler and lid.




In a preferred embodiment, there are two pairs of the openings, one on each of the opposed sides of the cooler body and lid and two of the bungee cords, one for each of the two pairs of openings.




Preferably, one of the bungee cords includes a hook intermediate its ends so it can be hooked to the opposite bungee cord across items to be transported.




According to still another facet of the invention, there is provided a cooler that includes a cooler body of insulating material having an internal cavity and an upper access opening as before, together with a cover for the access opening. A hinge pivots the cover to the cooler body and a recess is located in the cover so as to face the cavity in the body. A flexible, fabric-like panel is secured to the cover about the recess to define an item-receiving pocket between the cover and the panel.




Preferably, the panel is formed of a mesh.




In a preferred embodiment, the recess in the panel are rectangular and the panel is secured to the cover about three sides of the recess. The panel further includes a free side defining an access opening to the pocket.




As a consequence of this construction, items that are to be placed in the cooler, but are to be remain dry or are subject to crushing, may be stored in the pocket on the underside of the cover to the free from contamination by water from melting ice and/or the possibility of crushing by moving beverage containers or the like.




According to still another facet of the invention, a cooler is provided that includes a cooler body of insulating material and which has a cavity with an upper access opening. A cover is pivoted to the body for movement between positions opening and closing the access opening and at least two wheels are rotatably mounted on the body for rotation about a wheel axis at the lowermost edge of the body. An elongated handle having an end pivotally mounted to the body for rotation about a pivot axis that is generally parallel to and spaced from the wheel axis is provided. The handle has an end opposed to the pivoted end and a first grip opening is located at the opposed end. A second grip opening is disposed between the ends and adjacent the first grip opening so that persons of tall stature may grip the handle through the first grip opening and persons of short stature may grip the handle through the second grip opening.




As a consequence, the cooler is well suited for easy transportation by persons of varying stature.




In a preferred embodiment, the handle includes opposed sides and the first grip opening is defined by first and second spaced webs extending between the sides. The first web is closest to the opposed end and is concave in the direction facing the pivotally mounted end.




As a consequence of this construction, a person pulling the cooler may grip the handle at one side or the other of the concave grip opening with the result that the cooler will track to one side of the person when being pulled so as to avoid interference with the legs or heels of the person using the same.




In a preferred embodiment, the second web is also concave in the direction facing the pivotally mounted end, providing the same function for persons of short stature.




According to another facet of the invention, a wheeled cooler generally as before, i.e., with a cooler body of insulating material and a cavity with an upper access opening, a cover pivoted to the body for movement between positions opening and closing the access opening, two wheels rotatably mounted on the body for rotation about a first axis, and an elongated handle having one end pivotally mounted to the body for rotation about a second pivot axis is provided. According to this facet of the invention, the cooler further includes a stop on the body and located to engage the handle and halt pivotal movement thereof at an angular position between the horizontal and the vertical to thereby rigidify the pivotal connection between the handle and the body to allow a person pulling the cooler by the handle to readily halt movement of the cooler. As a result of this feature of the invention, when a person pulling the cooler abruptly stops, as the cooler tends to move forward the handle encounters the stops rather than pivoting further towards a vertical position, which in turn halts movement of the cooler. Contact with the user's heels or legs is thereby avoided.




According to still another facet of the invention, there is provided a wheeled cooler generally as before. According to this facet of the invention, the body has opposed sides and the handle is pivoted to one of the opposed sides. Lifting grips are located on each of the opposed sides and an access opening extends through the handle and is positioned to allow access to the lifting grip on the other side through the handle. As a consequence, when the cooler is not being towed, it is readily lifted by the lifting grips without moving the handle.




Other objects and advantages will become apparent from the following specification taken in connection with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT




An exemplary embodiment of a portable cooler made according to the invention is illustrated in the drawings as a single exemplary embodiment of the invention. However, it is to be understood that while, ideally, all of the many features of the invention will be employed in a single structure, many of the features may be used independently of one another or in combination with just one or a few of the other features. No limitation to the use of all of the features of the invention in a single structure is intended except insofar as expressed in the claims.




Referring to

FIG. 1

, the exemplary embodiment of the portable cooler includes four principal components including a cooler body, generally designated


10


, a rectangular lid or cover, generally designated


12


, which is pivoted to the body


10


by means to be seen, a table, generally designated


14


, which is also pivoted to the body


10


, and a handle, generally designated


16


, which is pivoted to the body


10


.




Addressing the body


10


, the same includes a forward wall


18


, opposed side walls


20


,


22


, and a rearwall


24


. The same is generally rectangular in configuration and includes an upper edge


26


which surrounds an interior cavity


28


(FIG.


3


). The body


10


is made up of insulating material


30


as is well known Conventionally, the same will include an inner shell (not shown), an outer shell, and foam forming the insulating material


30


.




Also as seen in

FIG. 3

, the body


10


has a lower or bottom wall


32


and just above the junction of the bottom wall


32


and the rear wall


24


, axles


34


(only one of which is shown) respectively mount a pair of wheels


36


for rotation about a generally horizontal axis. Desirably, and as seen in

FIG. 1

, the wheels


36


are located in recesses


38


in the side walls


20


,


22


and extend just below the bottom wall


32


as seen in FIG.


3


.




On the end walls


18


,


24


, the body


10


includes integral handles defined by generally downwardly opening notches


38


. The user of the cooler may insert their fingers into the notches


38


to lift the cooler as, for example, when loading or unloading the same from the trunk of a vehicle. Desirably, the body


10


also includes, adjacent the wheels


36


, a removable drain plug


40


.




Turning now to the lid


12


, as seen in

FIG. 2

, the same includes a flat upper surface


42


and as seen in

FIG. 3

, a recess


44


in its lower surface and surrounded by a peripheral lip


46


. If desired, a seal and groove combination


48


may be disposed about the exterior of the lid


46


for sealing engagement with the upper edge


26


of the body


10


. At the end of the lid


12


corresponding to the rear wall


24


of the body


10


, a small hand grip recess


50


may be located to allow the user to easily grasp the lid


12


by its edge for opening purposes.




At its forward wall


18


, the body


10


includes an upstanding post


52


which extends upwardly of the upper edge


26


and which mounts a horizontally disposed pivot pin


54


which is parallel to the axles


34


. As seen in

FIGS. 1 and 2

, the corresponding edge of the lid


12


includes upstanding lugs


56


which are impaled on the pivot pin


54


so as to enable the lid


12


to be pivoted between opened and closed positions permitting or denying access to the interior cavity


28


.




As seen in

FIGS. 3 and 5

, the peripheral edge


46


of the undersurface of the lid


12


mounts a fabric-like panel


58


. In a preferred embodiment, the panel


58


is a somewhat resilient mesh and is rectangular in form, as is the recess


44


. Three edges


60


,


62


and


64


of the panel


58


are secured by a conventional fastener


66


to the lip


46


. The panel


58


also has a free edge


70


and with the recess


44


, defines a pocket


72


which is ideally suited for receipt of goods that are to be kept away from melting ice within the cavity


28


or which are subject to crushing. That is to say, the panel


58


and the recess


44


define a pocket


72


with the free edge


70


defining an access opening whereby items of the foregoing category may be located within the pocket


72


and suspended therein when the lid


12


is closed in an elevated position above melting ice and/or beverage containers such as cans or bottles. Thus, such items may be cooled along with others, but are thus protected from wetting and/or crushing.




The table


14


includes a flat table surface


72


which, when the table


14


is stowed, is in abutment with the upper surface


42


of the lid


12


. At one end, the table


14


includes upstanding lugs


74


which are located inwardly of the lugs


56


and outwardly of the post


52


and also impaled on the pivot pin


54


(

FIG. 3

) whereby the table


14


is pivotally mounted on the assemblage.




The table


14


includes a leg structure


78


which is pivoted by a pivot pin


80


to the side of the table


14


opposite the table surface


72


for movement between a stowed position such as shown in

FIG. 1

, for example, to a deployed position, such as shown in

FIGS. 2 and 3

. As best seen in

FIG. 2

, the leg structure


78


is generally U-shaped and includes a pair of legs


82


which are spaced from one another and interconnected by a bight


84


. The ends of the legs


82


are impaled on the pivot pin


80


. As seen in

FIG. 1

, immediately adjacent the point of attachment of the legs


82


to the pivot


80


. The surface


84


opposite from the table surface


72


includes a pair of upstanding projections


86


provided with flat stop surfaces


88


which face the legs


82


. The stop surfaces


88


limit movement of the leg


78


to approximately 90° between the stowed position illustrated in FIG.


1


and the deployed position illustrated in

FIGS. 2 and 3

.




Desirably, the surface


84


of the table


14


includes a recess


90


of the same configuration as the leg


78


to substantially fully receive the leg


78


in the retracted or stowed position as illustrated in FIG.


1


. If desired, suitable detents (not shown) may be employed to releasably retain the leg


78


within the recess


90


.




It is to be particularly noted that the vertical length of the leg


78


is substantially the same as the vertical distance between the bottom wall


32


of the body


10


and the upper edge


26


so that when the leg


78


is deployed, the table surface


72


will be horizontal.




Desirably, the side of the table


14


remote from the pivot


54


includes a small recess


94


which may receive the fingers of the user to assist in pivoting the table


14


away from the cover or lid


12


. In this recess, a projection


96


acts as a hook. The same is adapted to impale a container, such as a plastic garbage bag, and suspend the same from the edge of the table


14


. Additionally, the table surface


72


may have a plurality of glass holding recesses


98


at any desired location.




The table surface


72


is surrounded on three edges by a peripheral, relatively short wall


100


. The wall


100


helps to retain items on the table surface


72


when the table is in use. Similar restraint on the fourth side is provided by the post


52


and the lugs


56


,


74


.




Returning to

FIG. 1

, the sides


102


,


104


of the lid


12


overlying the walls


20


,


22


of the body


10


, include elongated, horizontal grooves


104


(only one of which is shown) which terminate in spaced openings


106


in the lid


12


. As seen in

FIG. 2

, conventional bungee cords


108


are located in the grooves


104


and have opposed ends extending through the openings


106


at the ends of each groove


104


. As seen in

FIG. 4

, within the cover or lid


12


, the ends of the bungee cords


108


terminate in knots


110


which hold the bungee cords


108


assembled to the lid


12


. The arrangement is such that each bungee cord


108


will be somewhat stretched when located in the groove, that is, in tension.




Generally centrally of one of the bungee cords


108


, a metallic hook


112


is located.




As a consequence of this construction, and with the assistance of a small recess


114


underlying the central part of each bungee cord


108


, the bungee cords may be pulled from grooves


104


and coupled together as illustrated in

FIG. 6

to overlie other items (not shown) to be transported with the cooler on the exterior thereof. In some instances, it may be desirable to add a third bungee cord


116


to extend between the two bungee cords


108


.




This arrangement provides for easy attachment of other items such as lawn chairs, towels, blankets, another cooler or the like to the upper surface of the cooler for transportation purposes. At the same time, because the bungee cords


108


are under tension, when they are not being used, they will withdraw into the grooves


104


to be out of the way and to remain therein until their use is required.




Turning now to

FIGS. 1

,


3


and


4


, the handle


16


will be described in greater detail. As seen in

FIG. 1

, the handle


16


includes spaced, opposed sides


120


,


122


whose ends


124


,


126


are captured on a pivot pin


130


(

FIG. 3

) located below the pivot pin


54


and just below the upper edge


26


of the body


10


. Extending diagonally just above the ends


124


,


126


are a pair of stop surfaces


128


,


130


against which the opposed sides


120


,


122


abut to limit movement of the handle


16


between the solid line and fragmentary dotted line positions illustrated in FIG.


4


. The purpose of this construction is to prevent the handle


116


from pivoting beyond the position shown


116


more toward or even past the vertical as, for example, when the user of the cooler stops walking. In such a case, the momentum of the cooler will tend to cause the same to continue to roll in the direction it is being pulled and into the heels or legs of the user. However, before that can occur, the leg sides


120


,


122


will abut the respective stops


128


,


130


to rigidify the connection between the handle


16


and the cooler body


10


. Assuming the user does not release the handle


116


at this time, this will immediately haltfurther rolling movement of the cooler before it comes into contact with the user's heels or legs.




Returning to

FIG. 1

, the handle


16


is seen to include two grip openings


134


and


136


. The opening


134


is at the end


138


of the handle


16


remote from the pivot


130


(

FIG. 3

) while the opening


136


is located between the ends of the handle


116


but closely adjacent the opening


134


. As can be seen from

FIG. 3

, this results in the presence of two gripping webs


140


,


142


extending between the sides


120


,


122


. It is to be particularly observed that the gripping web


140


is concave in the direction of the pivot pin


130


. It is also to be observed that the end


138


is enlarged in a direction transverse to the direction of elongation of the handle


16


and is bulbous in shape. As a consequence of this, the web


138


may be grasped on one or the other of its sides allowing the user to grasp the same at a location offset from the centerline of the cooler. As a consequence, when pulling the cooler, the cooler will track to one side of the user rather than directly behind the user where it might encounter the heels or legs of the user.




The web


142


is likewise concave in the direction of the pivot pin


130


for the same purpose.




The provision of two gripping webs


140


,


142


enables easy use of the cooler by persons of tall stature as well as short stature. A tall person may grip the web


140


while a person of short stature, such as a child, may grip the web


142


. In either case, the front wall


18


of the body


10


will be elevated above the underlying terrain sufficiently that it will not drag thereon and the cooler may be towed on the wheels


36


.




A further opening


150


defined by a web


152


located between the opening


150


and the opening


136


provides a means for access to the grip recess


38


on the front wall


18


of the body


10


so that the user need not be required to move the handle


16


to achieve such access. Additionally, the presence of the webs


140


,


142


and


152


provide great rigidity and structurally strength to the handle


16


as well.




From the foregoing, it will be appreciated that a portable cooler made according to the invention overcomes the many difficulties associated with the use of conventional portable coolers. For one, the table


14


may be deployed and used with the cover


12


in a closed position. Further, the cover


12


may be opened to achieve access to the contents, of the cavity


28


without having to remove objects from the table


14


.




The pocket


72


provides a means for storage of dry items or items that are subject to crushing at a location out of the way of melting ice and/or relatively heavy beverage containers within the cavity


28


which could crush such items.




The unique handle configuration provides several advantages. For one, the use of two grips in the form of the webs


140


,


142


allow the cooler to be pulled readily by persons of both short and tall stature. The presence of the stops


128


,


130


, prevent a pulled cooler from coasting into the heels or legs of the user when the user stops. Similarly, the curved configuration of the gripping webs


140


,


142


, allow the pulling force to be applied to one side of the centerline of the cooler, again to avoid contact between the cooler and the heels or legs of the user.




The unique arrangement of the bungee cords


108


and the hook


12


allow the cooler to not only be pulled to transport its contents, but to allow it to serve as a trailer for the support of other items such as lawn chairs, blankets, towels, etc., eliminating the need to both carry such items and pull the cooler as well. At the same time, the grooves


104


allow full retraction of the bungee cords so that they are out of the way when not being used. Similarly, the recess in which the leg


78


for the table


14


is received allows ready stowage of the table.
