ABSTRACT:
A portable cooler chest is disclosed having a collapsible storage bin for nonperishable items and wheels specially adapted for rolling on sand or soft soils. The collapsible storage bin includes foldable side panels and may be integrated with or separable from the lid of the chest. A cover is provided to cover the erected storage bin, or to enclose the collapsed storage bin between the cover and the lid. Pivotable rolling surface segments are hinged to the wheels such that the segments may be pivoted outwardly to augment the width of the rolling surfaces. The wheels are rotatably connected to the lower extent of the enclosure by pivoting spindles. The wheels may be pivoted under the bottom of the enclosure to prevent rolling of the chest and to place the wheels out of the way. Stowable retainer disks maintain the segments in the outwardly pivoted position. The wheels may be removed from the chest.
