a wheel - equipped carrying case can be carried by hand or rolled along the ground using an extensible u - shaped handle conveniently stored when not in use . the extensible handle slides through holes in substantially rigid end walls into a pair of storage tubes in the interior of the case . wheels are rotatively attached to ends of the storage tubes extending beyond one end wall . for added stiffness each end wall includes a flange around the periphery of the wall with a groove therein . the grooves accommodate the free ends of the side and bottom walls of the case during assembly . in an alternative embodiment , the extensible handle telescopes into tubes mounted on the bottom of the case and wheels are attached to the end wall opposite the end wall through which the extensible handle projects . one or more pivotally mounted support frames on the bottom of the case wheels allow the case to rest in a level position when it is not being carried or rolled . in another alternative embodiment the extensible handle is stored within a larger - diameter tube mounted on the bottom of the case with four metal or two plastic brackets , and is capable of being locked in extended position by spring - loaded buttons which pop up through holes in the handle tubing and storage tubing when the handle is fully extended .
