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.

A portable carrying case comprising in combination: first and second end walls, first and second side walls, a top wall, and a bottom wall defining an interior cavity, said bottom and end walls having first and second parallel spaced-apart storage tubes attached thereto, said case having mounting means for mounting said storage tubes, a pair of extensible members disposed in said spaced-apart storage tubes and having a first terminus and a second terminus, said first terminus being configured in a handle configuration and said first and second storage tubes having first and second spaced-apart wheels rotatably connected thereto, respectively, at an end opposite said first terminus, said extensible members being adapted to be received within said storage tubes; wherein each of said extensible members comprises first and second straight tube segments, said first segment telescopically receiving said second segment in operative relation thereto, wherein said first and second segments can be locked into extended positions by spring-loaded buttons transversely housed in said first and second tube segments, wherein said buttons are allowed to project through holes of corresponding diameter and circumferential position in said storage tubes and said second straight tube segments when said first and second straight tube segments are extended; wherein each of said end walls comprises a substantially planar sheet of rigid material with a transversely projecting rim portion and having an interiorly directed groove which receives a free edge of said side and bottom walls; and wherein said mounting means includes two pairs of brackets, one pair mounted on said case at said first end wall and one pair mounted on said case at said second end wall, each said bracket comprising a generally planar body portion with a central part cut on three sides and bent to a position 90 degrees away from said planar portion, said bent central part having a hole therein of sufficient diameter to allow passage of one of said storage tubes therethrough, said bracket further having an end portion closest to said bent central part and defining an inwardly facing channel, each said bracket having a plurality of mounting holes through said bracket for mounting said bracket to said case and said mounting means further comprising first and second means for securing said storage tubes in said mounting brackets.
