  • Patent number: 6814333
    Abstract: The invention provides a portable cooler stand having a collapsed or folded configuration for transportation and an unfolded configuration for supporting cooler off the ground within easy reach of users. The stand has four support legs. The legs are positionable roughly at the corners of a rectangle, with each support leg is linked to two adjacent support legs by a pair of folding positioning members. Two parallel load bars are pivotally connected to two adjacent support legs and may be extended to attach temporarily to the remaining two support legs to fix the length of the support cooler in its unfolded condition. One or more flexible belts are connected between the load bars to support a cooler or similar bulky object between the load bars. Under the weight of the cooler the load bars move toward one another until they contact the cooler, which fixes the width of the stand and completes the structure's rigidity.
