Abstract
A plurality of recesses are formed in the bottom of a suitcase in spaced relation with each other. A plurality of mounting devices are provided, each movably mounted in a corresponding one of the recesses. Each of a plurality of wheels is rotatably mounted on a corresponding one of the mounting devices. A control system in the suitcase selectively controls the movement of the mounting devices in the recesses in a manner whereby the wheels are spaced from the bottom of the suitcase for supporting the suitcase in one position and are retracted into the recesses in another position.
